The oxygen making device is provided with the oxygen outlet, and the display device includes the gas collection component that is linked together with the oxygen outlet, and when the oxygen making device was opened, the high concentration oxygen that its produced just can enter into in the gas collection component like this. The gas collecting component is provided with an opening, and the gas collecting component is provided with a cavity, and gas in the cavity can be discharged through the opening. A combustible element having an oxygen index greater than 21% may be disposed within the chamber of the gas collection member. The oxygen index is the minimum oxygen concentration required for the material to undergo flaming combustion in a nitrogen-oxygen mixture gas stream under specified conditions. In natural air, the volume percentage of oxygen is slightly less than 21%, and combustible components made of materials with oxygen index of more than 21% can not perform flame combustion in natural air, but can only perform flameless combustion. And the chamber, after being fed with the high-concentration oxygen generated by the oxygen generating device, has an oxygen concentration of more than 21%, and the combustible element made of the material with the oxygen index of more than 21% can be subjected to flame combustion in the environment. Through such a setting mode, when the oxygenerator was opened, the oxygen concentration that the high concentration oxygen that the oxygenerator produced made in the cavity after entering into the cavity was greater than 21%, under this oxygen concentration, in putting into the cavity with the combustible piece that is in flameless combustion state, combustible piece just can become flameless combustion by flameless combustion state to just also can prove that the oxygenerator can produce the oxygen of high concentration really, improve the oxygen concentration in the cavity.

When the air conditioner with the oxygen enrichment function is sold, a salesperson usually faces a problem that the oxygen enrichment function of the air conditioner cannot be intuitively displayed to a consumer, which may cause low credibility of the oxygen enrichment function and is not beneficial to the sale of products. Therefore, the invention provides a function display method of an air conditioner, which is characterized in that whether a human body enters a preset range of the air conditioner is detected through a human body detection module, if the human body enters the preset range, the human body is shown to be possibly interested in the air conditioner, and at the moment, a reminding module is controlled to send out a prompt of starting oxygen enrichment function display to remind that the oxygen enrichment function display can be carried out. After the prompt is heard, the display device can be used for displaying the oxygen enrichment function of the air conditioner for the user.

In this embodiment, the air conditioner is provided with the oxygenerator and can demonstrate the display device of the oxygen boosting function of air conditioner, and wherein, the oxygenerator is used for coming out the oxygen separation in the air, obtains the oxygen of high concentration. The oxygen generator is provided with an oxygen outlet, and an oxygen tube is usually provided at the oxygen outlet to send out oxygen generated by the oxygen generator. The display device comprises a gas collecting component, an oxygen outlet of the oxygen generating device is communicated with the gas collecting component through an oxygen conveying pipe, and thus, when the oxygen generating device is opened, high-concentration oxygen generated by the oxygen generating device can enter the gas collecting component through the oxygen conveying pipe.

The gas collecting component is provided with a cavity, and a combustible piece can be placed in the cavity, wherein the oxygen index of the combustible piece is more than 21%, such as natural incense, wood stick polyamide products, polycarbonate products and the like. The oxygen index is the minimum oxygen concentration required for the material to undergo flaming combustion in a nitrogen-oxygen mixture gas stream under specified conditions. In natural air, the volume percentage of oxygen is slightly less than 21%, and combustible components made of materials with oxygen index of more than 21% can not perform flame combustion in natural air, but can only perform flameless combustion. And the chamber, after being fed with the high-concentration oxygen generated by the oxygen generating device, has an oxygen concentration of more than 21%, and the combustible element made of the material with the oxygen index of more than 21% can be subjected to flame combustion in the environment.

step S10: detecting whether a human body enters a preset range of the air conditioner or not through a human body detection module;

in this embodiment, the air conditioner is configured with a human body detection module.

In step S10, the human body detection module, which may be an infrared detection module, is used to detect whether a user enters a preset range, and the infrared detection module can accurately detect whether the user enters the preset range. It should be noted that the technical means for detecting whether there is a user in the preset range by using the infrared detection module belongs to the conventional technical means in the field, and is not described herein again.

Of course, the human body detection module of the present invention may also be a radar detection module, and any specific detection method should not limit the present invention no matter what way is adopted to detect whether a user enters a preset range.

It should be noted that the human body detection module may perform real-time detection or detect according to a preset time interval, where the preset time interval may be 15 seconds, 30 seconds, 1min, 3min, and the like. Of course, these preset time intervals are only described by way of example, and are not limited thereto, and those skilled in the art can flexibly select the preset time intervals in practical applications, and in any case, the preset time intervals are adjusted and set, as long as whether a user enters the preset range can be accurately detected.

It should be noted that the preset range may be a detection range of the human body detection module during normal operation, or may be a range preset by a person skilled in the art according to experiments or experience. The preset range may be a range having a certain linear distance from the air conditioner, such as 0.8m, 1.2m, or 1.5m, and the preset range may be flexibly adjusted and set by a person skilled in the art.

Obviously, the human body detection module may be disposed on the air conditioner, or may be disposed on the display device, or on a remote controller, a mobile phone, a tablet computer, and other mobile terminals communicating with the air conditioner.

Step S20: if the human body enters the preset range, the reminding module is controlled to send out a prompt of starting oxygen enrichment function display.

In step S20, based on the detection result in step S10, if it is detected that a human body enters the preset range, indicating that a person comes in front of the air conditioner and is interested in the air conditioner, at this time, the reminding module is controlled to send out a prompt of "turning on the oxygen enrichment function display". The reminding module can be a voice reminding module, after detecting that a human body enters a preset range, the reminding module sends out a reminding sound of 'opening the oxygen enrichment function display', after hearing a prompt, a user is determined to stand in front of the air conditioner, and therefore the user can be displayed in time, and the oxygen enrichment function of the air conditioner is displayed through the display device. Of course, after the reminding module gives out the prompt, the air conditioner automatic control display device can be used for displaying.

Of course, the reminding module can also be a text reminding module, namely, the salesperson and the user are reminded by sending a text reminding mode, or the voice and text reminding module is reminded of the salesperson and the user by a voice and text mode.

It should be noted that the reminding module may be disposed on the air conditioner, or disposed on the display device, or on a remote controller, a mobile phone, a tablet computer, or other mobile terminal in communication with the air conditioner.

In a possible embodiment, in the state in which the combustible element is in flameless combustion, the following operations are carried out: controlling the oxygen generation device to start for a first preset time, and controlling the reminding module to send a prompt of 'starting oxygen enrichment'; and controlling the oxygen generation device to close the second preset time and controlling the reminding module to send a prompt of closing the oxygen enrichment. The part of the combustible element in the flameless combustion state is positioned in the chamber at the same time, before or after the oxygen generating device is controlled to be opened. When the oxygen enrichment function is displayed, the reliability of the oxygen enrichment function can be proved through the change of the part of the combustible element in the flameless combustion state. Through the control mode, when the oxygen enrichment function is displayed, the oxygen generation device can be controlled to be started for a first preset time and then be closed for a second preset time, if the first preset time is 1min, the second preset time is 2min, the reminding module is controlled to respectively send prompts of 'starting oxygen enrichment' and 'closing oxygen enrichment', the oxygen generation device can also be controlled to be stopped for the second preset time and then be started for the first preset time, if the second preset time is 1min, the first preset time is 1min, and the reminding module is controlled to respectively send prompts of 'closing oxygen enrichment' and 'opening oxygen enrichment'. When the oxygen generating device is started, the combustible piece is ignited, the combustible piece is in a flameless combustion state in the air, then half or two thirds of the ignited combustible piece is inserted into the chamber, and the part in the flameless combustion state is positioned in the chamber, or the whole combustible piece is placed into the chamber. This also allows at least the part of the combustible element that is in the flameless combustion state to be located in the chamber, the oxygen concentration in the chamber being different when the oxygen-generating device is turned on and off, the combustion state of the combustible element being changed between flaming combustion and flameless combustion. Through the change of the combustion state of the combustible element, the oxygen generator really generates high-concentration oxygen and introduces the oxygen into the chamber, so that the oxygen concentration in the chamber is improved, a user can intuitively know the oxygen enrichment function of the air conditioner, and the reliability of the oxygen enrichment function of the air conditioner is improved.

Obviously, before or after the oxygen generator is controlled to be started, the part of the combustible piece in the flameless combustion state can be positioned in the chamber or the whole combustible piece can be placed in the chamber, and a person skilled in the art can flexibly select a specific time when at least the part of the combustible piece in the flameless combustion state is positioned in the chamber, as long as the combustion state of the combustible piece can be changed from the flameless combustion to the flame combustion after the oxygen generator is started, and then the oxygen generator can be proved to be capable of generating oxygen with high concentration.

It should be noted that, the specific values of the first preset time period and the second preset time period are only an exemplary description, and obviously, the first preset time period and the second preset time period may also be other values such as 20 seconds, 45 seconds, 90 seconds, 150 seconds, 3min, etc., and the specific values of the first preset time period and the second preset time period may be the same or different, and those skilled in the art may flexibly select the specific values of the first preset time period and the second preset time period according to the volume of the chamber, the specific type of the combustible component, the oxygen generation speed of the oxygen generation device, etc., as long as the oxygen enrichment function of the air conditioner can be exhibited.

It should be noted that, the two operations of above-mentioned execution under combustible element is in flameless combustion state are not in proper order, can control earlier that oxygenerator opens first predetermineeing time length, and control and remind the module to send the suggestion of "opening the oxygen boosting", it predetermines time length to control oxygenerator to close the second again, and control and remind the module to send the suggestion of "closing the oxygen boosting", also can control earlier that oxygenerator closes the second and predetermineeing time length, and control and remind the module to send the suggestion of "closing the oxygen boosting", it is long when first predetermineeing to control oxygenerator to open again, and control and remind the module to send the suggestion of "opening the oxygen boosting". Those skilled in the art can flexibly select the application according to specific application scenarios.

In the following, a possible implementation manner of the function displaying method of the invention is described with reference to fig. 3 to 6 by taking an example of controlling the oxygen generating device to be opened for a first preset time period and then controlling the oxygen generating device to be closed for a second preset time period. Fig. 3 is a flowchart of detecting whether a human body enters a preset range through a human body detection module according to an embodiment of the present invention, fig. 4 is a flowchart of comparing brightness in two situations after an oxygen generator is turned on and turned off for a second preset time period according to an embodiment of the present invention, fig. 5 is a flowchart of comparing brightness in two situations after the oxygen generator is turned off for the second preset time period, turned on for a first preset time period and then turned off for a fourth preset time period according to an embodiment of the present invention, and fig. 6 is a flowchart of comparing images in three situations after the oxygen generator is turned on and turned off for the second preset time period, turned on for the first preset time period and then turned off for a fifth preset time period according to an embodiment of the present invention.

As shown in fig. 3, in a possible embodiment, the step S10 of detecting whether a human body is within a preset range of the air conditioner by the human body detection module further includes:

step S101: acquiring the stay time of a human body in a preset range;

step S102: and if the stay time is more than or equal to a third preset time, judging that someone enters a preset range.

In step S101, the human body detection modules such as the infrared detection module and the radar detection module are used to obtain the staying time of the human body in the preset range of the air conditioner. Taking the human body detection module as an infrared detection module as an example, the duration of shielding infrared rays emitted by the infrared detection module is counted, and then the stay duration of the human body in the preset range is determined.

In step S102, based on the staying time of the human body detected in step S101 within the preset range, the staying time is compared with a third preset time. If the stay time is more than or equal to a third preset time, if the stay time is 40 seconds, the third preset time is 20 seconds, and the fact that the human body stays in front of the air conditioner for a long enough time is indicated, it can be judged that the human body enters a preset range of the air conditioner, and the human body is interested in the air conditioner, so that the reminding module can be controlled to send a prompt of starting oxygen enrichment function display, and a salesman can timely display the oxygen enrichment function for a user under the prompt, so that the user can better know the oxygen enrichment function of the air conditioner.

If the staying time is less than a third preset time, if the staying time is 10 seconds and the third preset time is 20 seconds, it indicates that the human body may only pass through the air conditioner and is not interested in the air conditioner, and at this time, no action is performed.

It should be noted that the specific value of the third preset time period is only an exemplary description, and obviously, the third preset time period may also be other values such as 15 seconds, 25 seconds, 30 seconds, and the like, and those skilled in the art may flexibly select the third preset time period according to a specific application scenario.

As shown in fig. 4, in a possible implementation, the function display method of the present invention further includes:

step S31: after the oxygen generation device is controlled to be started, detecting first brightness in the cavity through a brightness detection module;

step S32: after the oxygen generation device is controlled to be closed for a second preset time, detecting second brightness in the cavity through the brightness detection module;

step S33: comparing the first brightness with the second brightness to obtain a first comparison result;

step S34: transmitting the first brightness, the second brightness and the first comparison result to a display module;

step S35: and displaying the first brightness, the second brightness and the first comparison result through the display module.

In this embodiment, the display device includes a brightness detection module, and this brightness detection module sets up in the cavity of gas collection component, can detect the indoor luminance of cavity in real time through this brightness detection module.

It should be noted that the brightness detection module may be a brightness detector, which is based on the photoelectric conversion principle and uses a high-precision silicon photocell as a sensing element, and an optical signal reaches the sensing element through an optical filter and is converted into an electrical signal, and then the electrical signal is processed by an integrated circuit to output a continuous linear proportional signal, i.e., a brightness value.

Obviously, the brightness detection module may also be a photodiode, and when no light is emitted, the resistance is infinite, and when light is emitted, the resistance may be as small as several hundred ohms, so that the current brightness can be determined according to the resistance value of the photodiode. Of course, the brightness detection module may be arranged in other manners as long as the brightness in the chamber can be detected in real time.

In step S31, the part of the combustible element in the flameless combustion is located in the chamber, and after the oxygen generator is controlled to be turned on, oxygen generated by the combustible element is sent into the chamber, so that the oxygen concentration in the chamber is rapidly increased, the combustion state of the combustible element is changed from the flameless combustion to the flame combustion, and at this time, the brightness in the chamber at this time is detected to be the first brightness by the brightness detection module such as the brightness detector.

In step S32, since the chamber is communicated with the outside through the opening, after the oxygen generator is controlled to be turned off for a second preset time period, if the second preset time period is 2min, the oxygen concentration in the chamber is slowly reduced to about 21%, at this time, the combustion state of the combustible element is flameless combustion, and the second brightness in the chamber is detected through the brightness detection module.

In step S33, the first luminance and the second luminance obtained in steps S31 and S32 are compared, e.g., the first luminance is 350cd/m²And the second luminance is 50cd/m². Wherein, cd/m²(candela/square meter) is a unit of luminance, i.e., a light emission luminance per unit projected area. Based on this, a first comparison result in which the first luminance is larger than the second luminance can be obtained.

In this embodiment, the display device further includes a display module, and the display module may be a display screen, a tablet computer, or other terminals communicating with the display device, or may be a display screen disposed on the display device. The display device includes an image acquisition module, which may be but is not limited to a camera, etc., and those skilled in the art can flexibly select.

In step S34, the first brightness, the second brightness and the first comparison result obtained in step S31, step S32 and step S33 are transmitted to a display module such as a mobile terminal or a display screen.

In step S35, the display module displays the first brightness, the second brightness and the first comparison result after receiving the first brightness, the second brightness and the first comparison result uploaded in step S34.

Therefore, a user can more intuitively know that after the oxygen generation device is started, the first brightness generated by the combustion of the combustible piece is larger than the second brightness generated by the combustion of the combustible piece after the oxygen generation device is closed for a second preset time, which means that after the oxygen generation device is started, the oxygen concentration in the cavity can be improved through the oxygen generated by the oxygen generation device, so that the combustible piece is in a flame combustion state, after the oxygen generation device is closed for the second preset time, the oxygen concentration in the cavity is reduced to about 21%, and the combustion state of the combustible piece is returned to a flameless combustion state, so that the situation that when the oxygen generation device is started, high-purity oxygen is really introduced into the cavity can be effectively proved, the oxygen concentration in the cavity is improved, the reliability of the oxygen enrichment function of the air conditioner is improved, and the product sale is facilitated.

As shown in fig. 5, in a possible implementation, the function display method of the present invention further includes:

step S32: after the oxygen generation device is controlled to be closed for a second preset time, detecting second brightness in the cavity through the brightness detection module;

step S41: detecting third brightness in the chamber through a brightness detection module within a first preset time period after controlling the oxygen generation device to be started and then to be closed for a fourth preset time period;

step S42: comparing the second brightness with the third brightness to obtain a second comparison result;

step S43: transmitting the third brightness and the second comparison result to the display module;

step S44: and displaying the second brightness, the third brightness and the second comparison result through the display module.

In step S41, after the oxygen generator is controlled to be turned on for a first preset time period, if the first preset time period is 1min, the oxygen concentration in the chamber is greater than 21%, then the oxygen generator is controlled to be turned off for a fourth preset time period, where the fourth preset time period is less than the second preset time period, and if the second preset time period is 1min and the fourth preset time period is 20 seconds, at this time, the oxygen concentration in the chamber is gradually decreased but is still slightly higher than 21%, at this time, the combustion state of the combustible element should still be flamed combustion, and a third brightness in the chamber is detected by the brightness detection module.

In step S42, the second luminance detected in step S32 is compared with the third luminance detected in step S41, such as the third luminance is 150cd/m²And the second luminance is 50cd/m². Based on this, the first comparison result in which the third luminance is larger than the second luminance can be obtained.

In step S43, the second brightness, the third brightness and the second comparison result obtained in step S32, step S41 and step S42 are transmitted to a display module such as a mobile terminal or a display screen.

In step S44, the display module displays the second brightness, the third brightness and the second comparison result after receiving the second brightness, the third brightness and the second comparison result in step S43.

Therefore, a user can clearly see that the combustible element is in a flameless combustion state within the fourth preset time period after the oxygen generation device is closed and is in a combustion state after the second preset time period according to the second brightness, the third brightness and the second comparison result, the combustible element is in the flameless combustion state within the fourth preset time period after the oxygen generation device is closed, and the combustible element is in the flameless combustion state after the oxygen generation device is closed and is in the second preset time period.

As an alternative embodiment, as shown in fig. 6, the function display method of the present invention further includes:

step S51: after the oxygen generation device is controlled to be started, a first image of the combustible piece is obtained through the image acquisition module;

step S52: after the oxygen generation device is controlled to be closed for a second preset time, a second image of the combustible piece is obtained through the image acquisition module;

step S53: the method comprises the steps that a third image of the combustible piece is obtained through an image acquisition module within the first preset time period after the oxygen generation device is controlled to be started and then is closed for a fifth preset time period; wherein the preset falling time is less than a second preset time;

step S54: transmitting the first image, the second image and the third image to a display module;

step S55: and displaying the first image, the second image and the third image through the display module.

In this embodiment, the display device includes an image acquisition module, and the image acquisition module is arranged in the cavity of the display device, and can acquire the image of the combustible element through the image acquisition module.

It should be noted that the image capturing module can be, but is not limited to, a camera, a still camera, etc., and those skilled in the art can flexibly select the image capturing module according to a specific application scenario.

In step S51, after the oxygen generator is controlled to be turned on, the oxygen concentration in the chamber is increased to more than 21%, and a first image of the combustible material is acquired by using an image acquisition module such as a camera, etc., wherein the combustible material can be clearly shown to be in a flaming combustion state in the first image.

In step S52, after the oxygen generator is controlled to be turned off for a second preset time, if the second preset time is 1min, the oxygen concentration in the chamber is reduced to about 21%, and a second image of the combustible element is obtained by using image acquisition modules such as a camera and a camera, where the second image clearly shows that the combustible element is in a flameless combustion state.

In step S53, after the oxygen generator is controlled to be turned on for a first preset time period and then turned off for a fifth preset time period, if the first preset time period is 1min and the fifth preset time period is 20 seconds, the oxygen concentration in the chamber begins to decrease but slightly higher than 21%, a third image of the combustible piece is obtained by using image acquisition modules such as a camera and a camera, and in the third image, it can be clearly shown that the combustible piece is in a flame combustion state, but the flame length generated by the flame combustion is shorter than that in the first image and the flame brightness is weaker than that in the first image.

It should be noted that when the image of the combustible element is acquired by the image acquisition module, the image can be continuously captured, or the images can be intermittently captured at preset time intervals, for example, one image can be captured every 2 seconds. A person skilled in the art can flexibly select a shooting mode of the image of the combustible component according to a specific application scene as long as the image reflecting the combustion state of the combustible component can be accurately acquired.

In this embodiment, the display device further includes a display module, and the display module may be a display screen, a tablet computer, or other terminals communicating with the display device, or may be a display screen disposed on the display device. The display device includes an image acquisition module, which may be but is not limited to a camera, etc., and those skilled in the art can flexibly select.

In step S54, the first image, the second image, and the third image obtained in steps S51, S52, and S53 are transmitted to a display module such as a mobile terminal or a display screen.

In step S55, the presentation module presents the first image, the second image, and the third image after receiving the first image, the second image, and the third image uploaded in step S54.

Therefore, a user can visually see from the first image, the second image and the third image through the display module, the combustion states of the combustible pieces in the three stages are different, the combustible pieces in the first image are obviously in a flame combustion state, the combustible pieces in the second image are obviously in a flameless combustion state, and the combustible pieces in the third image are in a flame combustion state, so that the oxygen generating device really introduces high-purity oxygen into the chamber when being opened, the oxygen concentration in the chamber is improved, and the oxygen concentration in the chamber is gradually reduced after the oxygen generating device is closed, so that the reliability of the oxygen enrichment function of the air conditioner is improved.

After detecting that a human body enters the preset range, the reminding module can send a prompt of 'starting oxygen enrichment function display', and at the moment, oxygen enrichment function display can be started. Before the oxygen enrichment function is displayed, if the combustible element is in an extinguishing state, the combustible element needs to be ignited so as to give an intuitive feeling to a user. A possible implementation of igniting the combustible element is explained below in connection with fig. 7. FIG. 7 is a flow chart of igniting the combustible element after determining that a human body has entered the predetermined range, in accordance with an embodiment of the invention.

As shown in fig. 7, in a possible implementation, the function display method of the present invention further includes:

step S100: moving the ignition device to the combustible element by the first mechanical arm;

step S200: the combustible element is ignited by the ignition device.

In this embodiment, the display device further includes an ignition device and a first mechanical arm, and the ignition device is used for igniting the combustible element, for example, the ignition device is an electronic ignition gun, an electronic igniter, and the like. When the oxygen-enriched function is displayed, firstly, an ignition signal is generated by the signal generator, the ignition controller controls the on-off of a primary circuit of the ignition coil according to the signal sent by the signal generator, high voltage is generated in a secondary circuit, and the high voltage is sent to each spark plug through a voltage divider to realize ignition and ignite a combustible component.

The ignition device is clamped on a first mechanical arm, and the first mechanical arm is used for moving the ignition device to the position of the combustible element. For example, the first robot arm includes a first motor and a first rack-and-pinion, a first clamping portion is provided on a rack of the first rack-and-pinion, and the ignition device is clamped in the first clamping portion. Obviously, the first mechanical arm may also be composed of a first motor and a first push rod, the first push rod is provided with a first clamping portion, and the ignition device is clamped by the first clamping portion on the first push rod. Of course, the first mechanical arm may be arranged in other ways, and those skilled in the art may flexibly select the first mechanical arm according to a specific application scenario as long as the ignition device can be moved to the combustible element.

It should be noted that, the ignition device and the first mechanical arm may both be disposed outside the housing, and after detecting that a human body enters the preset range, the ignition device is driven by the first mechanical arm to move and pass through the opening to reach the combustible element. Obviously, the ignition device and the first mechanical arm can also be arranged in the chamber, and after the fact that a human body enters a preset range is detected, the first mechanical arm is controlled to move to drive the ignition device to the position of the combustible element. Of course, the ignition device and the first mechanical arm may be arranged in other manners as long as the ignition device can be moved to the position of the combustible element by the first mechanical arm when the combustible element needs to be ignited, and then the combustible element is ignited by the ignition device without affecting the oxygen-enriched display function of the display device.

In step S100, after detecting that a human body enters a preset range, if the combustible element is in an extinguished state, the ignition device is moved to the combustible element by the control of the first mechanical arm to prepare for igniting the combustible element.

It should be noted that whether the combustible element is in the extinguished state may be determined by the image of the combustible element collected by the image collecting device, or may be determined by the brightness in the chamber detected by the brightness detecting device when the combustible element is located in the chamber. Of course, it is also possible to make all or a part of the chamber from glass or a transparent plastic such as polystyrene, acrylonitrile-butadiene-styrene copolymer, or other possible transparent materials, such as a conical flask, and observe whether the combustible element is in the extinguished state directly through the part made from the transparent material. Those skilled in the art can flexibly select the extinguishing device as long as the extinguishing device can accurately determine whether the combustible element is in the extinguishing state.

In step S200, the combustible element is ignited by the ignition device, so that the oxygen enrichment function can be performed.

Obviously, the display device may also include only an ignition device, not including the first mechanical arm, the ignition device being aligned with the combustible element, and the ignition device being controlled to ignite after detecting that a human body has entered the predetermined range.

Of course, the display device may not include the ignition device and the first mechanical arm, and after the human body is detected to enter the preset range, the salesperson may manually ignite the combustible element and then place the combustible element into the chamber.

In one possible embodiment, the display device further comprises a second robotic arm, the combustible element being held by the second robotic arm. It should be noted that, the specific arrangement mode of the second mechanical arm may include a second motor and a second rack-and-pinion, the combustible element is clamped at a second clamping portion of a rack of the second rack-and-pinion, and may also include a second motor and a second push rod, and the combustible element is clamped at a second clamping portion of the second push rod. The structure of the second mechanical arm can be the same as or different from that of the first mechanical arm, and a person skilled in the art can flexibly select the second mechanical arm according to a specific application scene.

The ignition device, the first mechanical arm and the second mechanical arm are all arranged outside the cavity, after the fact that a human body enters a preset range is detected, the ignition device is moved to the position of the combustible piece through the first mechanical arm, the combustible piece is ignited through the ignition device, and at the moment, the ignited part of the combustible piece is in a flameless combustion state. The portion of the combustible element in the flameless combustion state is then inserted into the chamber by a second robotic arm. If the oxygen generator is opened and the oxygen concentration in the chamber is higher than 21%, the part of the combustible element in the flameless combustion state can be quickly converted into the flame combustion state. If the oxygen-generating device has been closed for at least a second predetermined period of time and the oxygen concentration in the chamber is about 21%, the portion of the combustible element that is in the flameless combustion state remains in the flameless combustion state. If the oxygen making device is opened for the first preset time and closed for the fourth preset time at the moment, and the oxygen concentration in the cavity is slightly higher than 21%, the part of the combustible part in the flameless combustion state can be converted into the flameless combustion state. Therefore, the oxygen generator can be well proved to be capable of introducing oxygen into the chamber, improving the oxygen concentration in the chamber and improving the reliability of the oxygen enrichment function of the air conditioner.

Of course, the display device may not include the second mechanical arm, and the combustible element may be manually inserted into the first chamber and the second chamber by a salesperson after the combustible element is ignited when performing the oxygen enrichment display.

In summary, in the preferred technical solution of the present invention, when it is detected that a human body enters the preset range of the air conditioner, the reminding module is controlled to send a prompt of "starting oxygen enrichment function display", so as to remind that the oxygen enrichment function display can be performed. By the control mode, the display can be displayed for the user in time, and the oxygen enrichment function of the air conditioner is displayed through the display device. When the oxygen enrichment function is displayed, the oxygen generation device can be controlled to open the first preset time and then close the second preset time, the reminding module is controlled to respectively send the prompts of opening the oxygen enrichment and closing the oxygen enrichment, the oxygen generation device can also be controlled to close the second preset time and then open the first preset time, the reminding module is controlled to respectively send the prompts of closing the oxygen enrichment and opening the oxygen enrichment, when the oxygen generation device is closed and opened, the combustion state of the combustible piece can be changed, the flame combustion and flameless combustion are changed, through the change of the combustion state of the combustible piece, the situation that the oxygen generation device really generates high-concentration oxygen and introduces the oxygen into the chamber is explained, the oxygen concentration in the chamber is improved, a user can visually know the oxygen enrichment function of the air conditioner, and the reliability of the oxygen enrichment function of the air conditioner is improved. After the oxygen generation device is controlled to be started, the second preset time is closed, the fourth preset time is closed after the first preset time is started, the first brightness, the second brightness and the third brightness in the cavity are respectively obtained through the brightness detection module, the first brightness, the second brightness and the third brightness are uploaded to the display module, the brightness values are displayed through the display module, the oxygen generation device can be more visually seen to be started, the second preset time is closed, the fourth preset time is closed after the first preset time is started, the combustion state of the combustible piece changes, and therefore when the oxygen generation device is started, oxygen is really introduced into the cavity, the oxygen concentration in the cavity is improved, the reliability of the oxygen enrichment function of the air conditioner is improved, and the product sale is facilitated.
