Technical Field

The invention relates to the technical field of low-temperature smoking sets, in particular to a control method of a low-temperature smoking set.

Background

The traditional cigarette needs to be ignited and combusted by open fire to generate tobacco smoke, thousands of mixed substances harmful to human bodies are released by tobacco in the high-temperature and cracking processes, the mixed substances consist of volatile substances existing in gas and semi-volatile substances and non-volatile substances existing in particles, such as carbon monoxide, phenols, aldehydes, nicotine (nicotine), tar and the like, and the low-temperature baked tobacco product can greatly reduce the generation of harmful substances and is healthier.

The low-temperature baking type tobacco products on the market at present basically use the surrounding heating and central heating technology, the smoking material of the low-temperature baking type tobacco products is positioned in the cigarette, and the heating body is positioned in the appliance and is powered by a battery. During the use, the user packs into the cigarette and props up low temperature smoking set, open the switch on the smoking set, PCB control panel control battery makes it generate heat to the heat-generating body power supply, when heating to preset temperature, the supply current of PCB control panel control battery, make the heat-generating body keep at preset constant temperature, the user has taken out a cigarette back, or insert new cigarette again and aspirate, thereby or directly close the switch and close the power, all need manual operation, if the user forgets to close the switch, the heat-generating body can only close the power with the help of the outage protection after working for a long time, cause very big energy waste easily, it is very inconvenient to use.

Disclosure of Invention

In order to solve the problems in the prior art, the invention provides a control method of a low-temperature smoking set, which is characterized in that the smoking times of a user are counted by detecting the temperature change of a smoke outlet or an air inlet of the low-temperature smoking set, and then whether the cigarette is completely combusted is judged, so that when the user finishes smoking one cigarette, the low-temperature smoking set is controlled to be closed in time, the energy waste is avoided, and the safety of the user is ensured.

The invention provides a control method of a low-temperature smoking set, which comprises the following steps:

step S1: initializing a smoking count value N to 0 when the low-temperature smoking set is started;

step S2: detecting the temperature T1 of the preset position of the low-temperature smoking set;

step S3: detecting the temperature T2 of the preset position of the low-temperature smoking set after a preset time interval T;

step S4: calculating the absolute value T of the temperature difference between the temperature T1 and the temperature T2;

step S5: when the absolute value of the temperature difference T is less than a preset temperature T0, returning to step S2, and when the absolute value of the temperature difference T is greater than or equal to a preset temperature T0, adding one to the suction count value N to obtain a new suction count value N;

step S6: when the new suction count value N is less than the preset suction number N0, returning to step S2; when the new smoking count value N is larger than or equal to the preset smoking times N0, cutting off the power supply of the low-temperature smoking set and closing the low-temperature smoking set;

wherein, the low temperature smoking set preset position is a low temperature smoking set outlet or a low temperature smoking set inlet.

In the scheme of the invention, when a user uses the low-temperature smoking set, firstly, a starting button is pressed to start the low-temperature smoking set, at the moment, the low-temperature smoking set automatically initializes a smoking count value N to zero, then, the temperature of a smoke outlet (or an air inlet) is detected at regular time according to a preset time interval T, then, the absolute value T of the temperature difference between the temperature T1 of the smoke outlet (or the air inlet) and the temperature T2 of the smoke outlet (or the air inlet) collected at adjacent time points is calculated, and when the absolute value T of the temperature difference is smaller than the preset temperature T0, the user does not finish the action of smoking a cigarette in the current time interval T, so the step S2 is returned, and the temperature of the smoke outlet (or the air; when the absolute value T of the temperature difference is greater than or equal to the preset temperature T0, it indicates that the user has finished smoking a cigarette during the time interval T, so the value of the puff count value N for recording the number of the user smoking mouths needs to be increased by one to record the current smoking action of the user. Because the number of the cigarette outlets of each cigarette is determined, the number of the corresponding cigarette outlets is determined according to the cigarette variety, and the number of the cigarette outlets is used as the preset number, when the smoking count value N is greater than or equal to the preset smoking number N0, the user is very likely to have smoked one cigarette, so that the circuit of the low-temperature smoking set is automatically cut off, and the low-temperature smoking set is closed.

The scheme of the invention is to use the temperature change of the smoke outlet (or the air inlet) of the low-temperature smoking set to judge whether a user finishes one smoking action.

When a cigarette is inserted into the low-temperature smoking set and started to heat the smoking set, the heating body of the smoking set begins to heat up, the smoking set also begins to slowly heat up, the temperature of the cigarette outlet of the smoking set is slowly raised, in the state, the temperature raising process is gentle, and the difference value of the temperature measured at fixed interval time is small. When a user starts to suck, smoke heated by the cigarette flows out from the smoke outlet under the action of suction force of the user, and because the temperature of the smoke flowing out of the smoke outlet is obviously higher than that of the smoke outlet when the user does not suck the cigarette (the temperature is 10-50 degrees higher under normal conditions), whether the user has suction action or not can be judged by detecting the temperature difference change of the smoke outlet. (when the predetermined temperature sensing location is the air inlet of the low temperature smoking set, the temperature of the air inlet will increase as the smoking set heats up after the user initiates heating

When the user is judged to have one smoking action, the smoking count value N is accumulated (the smoking count value is recorded), and whether N is larger than a preset value N0 is judged, namely, whether the user takes a few cigarettes or not is judged, and whether the upper limit of the smoking times of each cigarette is reached or not is judged, when N is larger than or equal to N0, the number of the cigarettes smoked by the user is equal to or exceeds the number of the cigarette outlets of one cigarette, at the moment, the power supply can be controlled to be cut off, the power supply is ensured not to supply power to the heating body any more, and. If the user needs continuous second cigarette suction, when the third cigarette suction, insert the cigarette into the smoking set, only need press the on-off key once more and start the heating function and can carry out next suction circulation.

Further, the temperature T1 and the temperature T2 are collected by a thermistor arranged at a preset position of the low-temperature smoking set.

Through set up thermistor at low temperature smoking set outlet (or air inlet), can be when accurate acquisition temperature value, effective control manufacturing cost is fit for commercial popularization.

Further, the preset time interval t ranges from 0.5 second to 10 seconds.

According to the statistical investigation, when a user smokes, the time interval of each smoking action is generally between 0.5 second and 10 seconds, so the value range of the temperature sampling time interval of the scheme of the invention is also set to be between 0.5 second and 10 seconds, and the temperature of the smoke outlet can be conveniently and accurately acquired.

Further, the preset temperature T0 ranges from 10 ℃ to 50 ℃.

According to statistical investigation, each time of the smoking action of the user normally causes the temperature of the smoke outlet (or the air inlet) to change between 10 ℃ and 50 ℃, so the value range of the preset temperature T0 is set to be 10 ℃ to 50 ℃ in the scheme of the invention, which is convenient for accurately judging whether the user performs the smoking action.

Further, the preset suction times N0 are determined according to the cigarette varieties.

Because the smoking times of cigarettes of different cigarettes are determined, the preset smoking times are determined according to the cigarette varieties, and therefore whether a user has smoked a cigarette is judged more accurately.

The low-temperature smoking set sold in the market needs to be matched with fixed cigarettes, and no smoking set which can be matched with various cigarettes exists at present, so that the smoking set can be controlled to be closed and heated by setting the number of suction openings. The temperature change during pumping is very obvious, and the inaccurate judgment caused by different temperature difference changes caused by the pumping amount can not occur.

After the air is sucked to a certain number of openings, the heating is stopped, and the air conditioner is also a protective measure, so that the heating device is prevented from working for a long time under an unnecessary condition, and the energy consumption is avoided.

Detailed Description

In order to further facilitate the understanding of the contents of the present invention, the following embodiments are further described.

Fig. 1 shows that the embodiment of the invention provides a control method of a low-temperature smoking set, which comprises the following steps: step S1: initializing a smoking count value N to 0 when the low-temperature smoking set is started; step S2: detecting the temperature T1 of the preset position of the low-temperature smoking set; step S3: detecting the temperature T2 of the preset position of the low-temperature smoking set after a preset time interval T; step S4: calculating the absolute value T of the temperature difference between the temperature T1 and the temperature T2; step S5: when the absolute value of the temperature difference T is less than a preset temperature T0, returning to step S2, and when the absolute value of the temperature difference T is greater than or equal to a preset temperature T0, adding one to the suction count value N to obtain a new suction count value N; step S6: when the new suction count value N is less than the preset suction number N0, returning to step S2; and when the new smoking count value N is greater than or equal to the preset smoking times N0, cutting off the power supply of the low-temperature smoking set and closing the low-temperature smoking set.

In this embodiment, the predetermined position of the low temperature smoking set is a low temperature smoking set outlet. When a user uses the low-temperature smoking set, firstly, a starting button is pressed to start the low-temperature smoking set, the low-temperature smoking set automatically initializes a smoking count value N to zero, then, the temperature of a smoke outlet is detected at regular time according to a preset time interval T, then, the absolute value T of the temperature difference between the smoke outlet temperature T1 and the smoke outlet temperature T2 collected at adjacent time points is calculated, when the absolute value T of the temperature difference is smaller than the preset temperature T0, the user does not finish the action of smoking a cigarette between the time interval T, so that the step S2 is returned, and the temperature of the smoke outlet of the low-temperature smoking set is continuously detected; when the absolute value T of the temperature difference is greater than or equal to the preset temperature T0, it indicates that the user has finished smoking a cigarette during the time interval T, so the value of the puff count value N for recording the number of the user smoking mouths needs to be increased by one to record the current smoking action of the user. Because the suction frequency of each cigarette is determined, the corresponding suction frequency is determined according to the cigarette variety, and the suction frequency is taken as the preset suction frequency when the suction count value N is greater than or equal to the preset suction frequency N0, the user is very likely to finish smoking one cigarette, so that the circuit of the low-temperature smoking set is automatically cut off, and the low-temperature smoking set is closed.

In summary, the embodiment of the present invention discloses a method for controlling a low temperature smoking set, which utilizes the temperature change of the smoke outlet of the low temperature smoking set to determine whether a user has completed a smoking action. When the times of the smoking actions of the user reach the number of the cigarette outlets of the cigarettes, the power supply of the low-temperature smoking set is automatically cut off, the low-temperature smoking set is closed, the energy is saved, and the safety of the user is ensured. When the user needs to smoke the second cigarette, the user only needs to press the switch key again to start the low-temperature smoking set. The scheme of the invention has small transformation difficulty and accurate and effective control flow, and is suitable for commercial popularization.
