Fig. 3 is a flowchart illustrating a hand-drying operation execution method according to an exemplary embodiment, and the hand-drying operation execution method is applied to a hand-drying machine, which may be the hand-drying machine illustrated in fig. 1, as illustrated in fig. 3. The method may include the following steps.

In step 301, user characteristic information of a current user is acquired through sensor data acquired by a sensor component on the hand dryer; the sensor assembly comprises at least one of a first image capturing assembly facing the front of the hand dryer, and a sensor unit facing the hand drying area of the hand dryer.

In an embodiment of the present disclosure, the hand dryer includes a sensor assembly, which may be a first image capturing assembly facing the front of the hand dryer and a sensor unit facing the hand drying area of the hand dryer, or any one of them. The hand dryer can acquire user characteristic information of the current user through data acquired by the sensor assembly.

Optionally, when the sensor component includes the first image capturing component and the sensor data includes a front image of the user in front of the hand dryer, the front image of the user in front of the hand dryer is subjected to image recognition to obtain user attribute information of the current user.

The image acquisition component can be a component mainly composed of a camera, when a user is in a certain distance in front of the hand dryer, the hand dryer takes pictures of the user through the camera, the acquired user image is analyzed through a biological image recognition function, and user attribute information can be obtained through analyzing the characteristics of the user in the image.

Wherein the user attribute information includes at least one of age, gender and height.

For example, when a user arrives 2m in front of the hand dryer, the hand dryer takes a picture of the user through the camera of the first image acquisition component, the obtained user image can be obtained according to an algorithm that the height of the user is 1.7m and the user is a young male, and the obtained user attribute information is added into the algorithm for judging the working mode for subsequent calculation.

The main body of the hand dryer can determine the position of the main body of the hand dryer on the supporting rod through the height information of the user in the attribute information of the user.

Optionally, the hand dryer may determine a target position of the hand dryer body on the support bar according to the user attribute information.

The position of the hand dryer main body on the supporting rod can be determined through the obtained height information of the user, and the horizontal position of the height of the user with the corresponding proportion is obtained and used as the target position of the hand dryer main body on the supporting rod.

For example, when the camera assembly in the first image acquisition assembly acquires a user image, and the actual height of the user is 1.7m by calculating and analyzing the user image, the position of the hand dryer main body, which is 1m away from the ground, can be obtained by a fixed algorithm according to the proportion of the height to the approximate position of the hand, and the position of the hand dryer main body, which is 1m away from the ground, can be determined as the target position of the hand dryer main body on the support rod.

Optionally, after the target position is determined, the hand dryer body can be controlled by the servo assembly to slide in the vertical direction, so as to be adjusted to the target position on the supporting rod.

The hand dryer comprises a hand dryer body, a servo assembly and a supporting rod; the hand dryer main body is connected with the supporting rod through the servo assembly.

The mode that the hand dryer main body moves can be that the hand dryer main body moves on the supporting rod by utilizing the servo assembly.

For example, please refer to fig. 4, which shows a schematic structural diagram of a hand dryer according to an embodiment of the present disclosure. As shown in fig. 4, the servo assembly of the hand dryer may be composed of a pulley 402 and a motor 404, and the rod-shaped structure of the sliding groove 401 is a support rod, which may be fixed on the wall. The hand dryer body 403 is movable up and down in the chute 401 by means of a pulley 402. The motor 404 operates to rotate the pulley 402 on one side in the same direction and the pulley 402 on the other side in the opposite direction. When the left pulley 402 rotates clockwise and the right pulley 402 rotates counterclockwise, the hand dryer main body 403 moves upward along the chute 401; when the right pulley 402 rotates clockwise and the left pulley 402 rotates counterclockwise, the hand dryer main body 403 moves downward along the chute 401.

Wherein, the hand dryer can judge the moving direction of the hand dryer body along the chute 401 according to the actual situation requirement.

For example, referring to fig. 5, which shows a schematic diagram of position adjustment of a hand dryer main body according to an embodiment of the present disclosure, when an initial position of the hand dryer main body is 0.5m away from the ground, and when it is detected that a height of a hand of a user may be 1m away from the ground, the motor 404 operates to drive the left pulley 402 to rotate clockwise, and the right pulley 402 rotates counterclockwise, so that the hand dryer main body 403 moves upward along the chute 401 by 0.5m to reach a target position.

For example, referring to fig. 6, which shows a schematic diagram of another position adjustment of the hand dryer main body according to an embodiment of the present disclosure, when the initial position of the hand dryer main body is 1.2m away from the ground, and when it is detected that the height of the hand of the user is 1m away from the ground, the motor 404 operates to drive the right pulley 402 to rotate clockwise, and the left pulley 402 rotates counterclockwise, so that the hand dryer main body 403 moves downward 0.2m along the chute 401 to reach the target position.

Optionally, when the sensor assembly includes the sensor unit, the hand feature information of the current user is acquired through the sensor data acquired by the sensor unit.

Wherein, the sensor unit includes at least one in temperature and humidity sensor and the second image acquisition subassembly.

Optionally, when the sensor unit includes the second image capturing component, the sensor data includes a hand image of the current user; the hand feature information includes the amount of water present on the surface of the user's hand.

For example, in the case where the sensor unit includes only the second image capturing element, when the user puts the hand in a recognizable area of the second image capturing element, the second image capturing element may capture image information of the current hand of the user. The water volume information of the current user's hand surface may be obtained by analyzing the current hand image.

For example, under the condition that the sensor unit comprises the temperature and humidity sensor and the second image acquisition assembly, when a user places a hand in an inductible area of the temperature and humidity sensor and a recognizable area of the second image acquisition assembly, the temperature and humidity sensor can acquire temperature and humidity data of the hand of the current user, meanwhile, the second image acquisition assembly can acquire image information of the hand of the current user, and water volume information of the surface of the hand of the current user is obtained by analyzing an image of the current hand.

In step 302, a target operation mode is determined according to the user characteristic information.

In the embodiment of the disclosure, the hand dryer comprehensively judges and determines the target working mode through all or part of the user attribute information acquired by the first image acquisition assembly, the hand temperature and humidity data acquired by the temperature and humidity sensor and the water amount information of the hand surface of the current user acquired by the second image acquisition assembly.

The working mode can comprise setting of the wind speed, the wind temperature and the predicted wind outlet time.

Optionally, the wind speed can be divided into a low gear, a medium gear and a high gear; the wind temperature can be divided into low grade, medium grade and high grade; the predicted air outlet time can be judged according to temperature and humidity data and water quantity information of the surface of the hand of the current user or any one of the temperature and humidity data and the water quantity information, and can also be divided into low grade, medium grade and high grade.

The higher the wind speed, the better the hand drying effect of the hand dryer; the higher the air temperature, the better the hand drying effect of the hand dryer.

Optionally, when the hand dryer includes the first image acquisition component and the sensor unit, the user characteristic information may be obtained comprehensively through the first image acquisition component and the sensor unit.

The hand dryer can determine part of working modes through the user attribute information acquired by the first image acquisition assembly.

For example, the hand dryer can obtain the age and gender of the target user through the user attribute information acquired by the first image acquisition component. When the target user is detected to be a child, the wind speed can be set to be a low gear, and the wind temperature can be set to be a medium gear; when the target user is detected to be female, the wind speed can be set to be middle, and the wind temperature can be set to be middle.

The hand dryer can determine part of working modes through all or part of hand temperature and humidity data acquired by the temperature and humidity sensor and water quantity information of the surface of the hand of the user acquired by the second image acquisition assembly.

For example, referring to fig. 7, which shows a schematic diagram of determining an operation mode according to an embodiment of the present disclosure, as shown in fig. 7, when the acquired hand humidity data is high or the acquired water amount on the hand surface of the user is high, the wind speed may be set to a high range.

For example, referring to fig. 8, which shows a schematic diagram of another determination operation mode related to the embodiment of the present disclosure, as shown in fig. 8, when the acquired hand humidity data is low or the acquired water amount on the hand surface of the current user is low, the wind speed may be set to a low gear.

And setting the predicted air outlet time according to the hand humidity data or the current water quantity on the surface of the hand of the user. When the hand humidity data is low or the obtained water amount on the surface of the hand of the user is low, the air outlet time is predicted to be low; when the acquired hand humidity data is high or the acquired water amount on the surface of the hand of the current user is large, the predicted air outlet time is high; and when the acquired hand humidity data or the acquired water amount on the surface of the hand of the user is in a fixed range, the predicted air outlet time is the middle gear.

In this embodiment of the application, the target operation mode is comprehensively determined by the hand dryer through all the user attribute information acquired by the first image acquisition component, the hand temperature and humidity data acquired by the temperature and humidity sensor, and the water amount information of the current hand surface of the user acquired by the second image acquisition component.

Optionally, the hand dryer may also determine the target operating mode through partial information therein, for example, the hand dryer may also determine the target operating mode through any one of user attribute information and hand characteristic information of the current user (including hand temperature and humidity data or water amount information on a hand surface); alternatively, the hand dryer may determine the target operation mode by using any one or two of the user attribute information, the hand temperature and humidity data, or the water amount information on the hand surface.

In step 303, the hand dryer is controlled to perform a hand drying operation according to the target operation mode.

In the embodiment of the disclosure, the temperature and humidity sensor acquires hand temperature and humidity data every fixed time, the second image acquisition assembly acquires water volume information of the surface of the hand of the current user every fixed time, and the wind speed and the wind temperature are adjusted according to the hand temperature data and the water volume of the surface of the hand of the current user every time.

For example, the hand dryer can determine that the wind speed is high, the wind temperature is medium, the predicted wind-out time is medium, and the medium of the predicted wind-out time of the hand dryer can be set to 1 minute according to the characteristic information of the user initial state. After the hand dryer performs hand drying operation for 30s, hand humidity data and the water amount on the surface of the hand of the user are determined through the second image acquisition assembly or the temperature and humidity sensor, and it can be judged that the current wind speed can be adjusted to be in a medium range, and the current wind temperature can be adjusted to be in a low range.

In step 304, operation prompt information is determined according to the hand image, and the operation prompt information is used for instructing the current user to perform user operation related to hand drying.

Optionally, it is determined from the hand image whether a hand-drying effect has been achieved.

If the hand drying effect is achieved, determining first operation prompt information, wherein the first operation prompt information is used for prompting that the hand drying of the current user is finished; and if the hand drying effect is not achieved, determining second operation prompt information, wherein the second operation prompt information is used for prompting the current user to keep the hand in the hand drying area continuously.

For example, when the predicted air-out time is reached, the hand dryer prompts the user not to stop hand drying operation temporarily through voice prompt by acquiring current hand temperature and humidity data and water amount information of the surface of the hand of the current user if the hand of the current user is still moist, and meanwhile, the hand dryer continues to perform hand drying operation until the current hand temperature and humidity data and the water amount information of the surface of the hand of the current user are displayed to achieve a hand drying effect and stop the hand drying operation; if the current hand of the user is determined to achieve the hand drying effect in the hand drying process, the user is informed of the completion of the hand drying operation through voice prompt, and the hand drying process is finished.

Optionally, a target hand pose is determined from the hand image.

And determining third operation prompt information according to the target hand gesture, wherein the third operation prompt information is used for prompting the current user to adjust the hand gesture to the target hand gesture.

For example, when the second image acquisition component acquires that the hand posture of the current user is a fist shape, the hand dryer can inform the user that the palm is spread by voice prompt.

In step 305, the prompt is presented.

In the embodiment of the present disclosure, the first operation prompt message, the second operation prompt message, and the third operation prompt message are sent through the voice system of the hand dryer according to the actual situation.

To sum up, according to the scheme shown in the embodiment of the present disclosure, the user characteristic information of the current user is obtained through the sensor data acquired by the sensor component on the hand dryer, the sensor component includes at least one of the first image acquisition component facing the front of the hand dryer and the sensor unit facing the hand drying area of the hand dryer, the target working mode is determined according to the user characteristic information, the target working mode is one of at least two working modes of the hand dryer, the hand dryer is controlled to execute the hand drying operation according to the target working mode, and in the process, the hand dryer can automatically select a proper working mode from the multiple working modes through the sensor data, so that the effect of the hand drying operation of the hand dryer is improved.
