Description

Heating non-combustion smoking device and heating control method and heating control system thereof

Technical field

The invention relates to the field of electric control, and in particular to a heating and non-combustion smoking appliance and a heating control method and heating control system thereof.

Background technique

Heat-not-burn cigarettes are different from traditional cigarettes. The “low-temperature cigarettes” designed with the idea of “heat-not-burn” can heat the tobacco leaves just enough to give off the flavor without igniting the tobacco leaves. Under normal circumstances, ordinary cigarettes will produce many harmful substances when they are smoked at a high temperature of 350°C to 600°C, while low-temperature cigarettes are below 300°C and harmful substances will be reduced. Specifically, taking emissions as an example, heat-not-burn tobacco products are only about 5% of traditional tobacco. From the perspective of cytotoxicity, heat-not-burn tobacco products account for about 14% of traditional cigarettes.

In addition, heat-not-burn products are closer to traditional cigarettes in terms of taste and smoking experience, allowing smokers to feel the real tobacco taste and being easier to accept.

As mentioned above, heat-not-burn tobacco products use an external heat source to heat the tobacco instead of igniting the tobacco to produce tobacco flavor gas. There are charcoal heating, electric heating and other methods. Critically, heat-not-burn tobacco products need to be equipped with special smoking utensils, and the heating temperature and time can be controlled more accurately, so that "heat-not-burn" can be realized. Obviously, special heat-not-burn smoking utensils need to be equipped with more complicated heating Modules, energy modules and control modules, so the specific product of cigarettes is much larger than that of traditional cigarette products. Intuitively described, traditional cigarette products are in accordance with regulations, from dozens to dozens of cigarettes are placed in cigarette boxes, and some cigarette boxes also have a friction ignition configuration, which is very convenient for carrying and storing. However, for the current heating non-combustion products on the market, the cigarettes are placed in a cigarette case. Due to the heating principle, the cigarette case needs to be processed for humidity maintenance. In addition, smoking utensils that heat the cigarettes during smoking are also required. Specially equipped with charging box.

In the prior art, a heating switch is provided on the smoking device. When the user uses the smoking device to smoke, he needs to turn on the heating switch, and the smoke is heated by the heating element built in the smoking device to a temperature that can be smoked before smoking. However, the aforementioned prior art still has the following shortcomings: the user needs to manually turn on the heating switch before heating the smoke in the smoking set, which is very inconvenient. Moreover, if the user does not turn off the heating switch in time after turning on the heating switch, the heating element in the smoking set will continue to heat the smoke during the user’s smoking interval, resulting in a waste of energy and reducing the amount of smoke that can make the user smoke after each charging of the smoking set. count. If you want to increase the number of cigarettes by increasing the battery capacity, you need to increase the volume and weight of the smoking device itself, which is not convenient for the user to carry. Therefore, technicians in the industry are very concerned about how to increase the efficiency of battery power usage while keeping the size of the smoking appliance unchanged.

Detailed ways

In order to make the purpose, technical solutions, and advantages of the present application clearer, the technical solutions of the present application will be described clearly and completely in conjunction with specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of this application.

The technical solutions provided by the embodiments of the present application will be described in detail below with reference to the accompanying drawings.

In order to increase the number of cigarettes that the user can smoke after each charging of the smoking device, an enabling switch can be set on the smoking device. When the user turns on the enable switch, the smoking appliance can detect whether the user is smoking. If it is detected that the user has started smoking, that is, when the user has placed the cigarette in his mouth and has performed the action of inhaling, the heating element is controlled to heat the cigarette to a preset temperature so that the user can smoke. Among them, the preset temperature refers to a preset temperature that heats the smoke to a temperature at which the user can smoke normally. Of course, the smoke is heated because it is detected that the user starts smoking. This leads to a period of heating before the smoke can be heated to a smoking temperature. During this period of time, the user began to inhale, but did not feel smoking, which resulted in a very poor user experience during this period.

Therefore, after the user turns on the enable switch, the power supply in the smoking set can heat the heating element to a lower temperature through a lower power. For ease of description, this temperature is referred to as the first temperature. Wherein, the first temperature is lower than the temperature when the user can smoke. By heating the heating element to the first temperature to preheat the smoke, the user's experience during the above period of time can be effectively improved.

Among them, the smoking appliance may be provided with an enable switch, and perform corresponding functions after the user turns on the enable switch. It is also not necessary to set the enable switch, and by default, the smoking device can perform the corresponding function when the power supply is available.

Of course, although the above solution proposed in this application can solve the problems mentioned in the background art, there are still some shortcomings: after the user turns on the enable switch, even if the user does not perform the action of smoking, the smoking appliance will continue to The heating element is heated to maintain the first temperature. This still causes a waste of energy.

To solve this problem, the embodiment of the present application also provides a heating control method for heating and not burning smoking set. When the user is not smoking or not preparing to smoke, the heating element is not heated, or the heating element is maintained at the second temperature with extremely low power. Wherein, the second temperature is less than the first temperature. Then, when the user is about to smoke, the heating element is preheated to heat the heating element to the first temperature or about the first temperature. Then, when it is detected that the user is smoking, the heating element is heated to a preset temperature. It should be noted that in the above embodiment, when the heating element is preheated, not only can it be heated to the first temperature or about the first temperature, but it can also be preheated to other temperatures lower than the preset temperature. . In the embodiments of the present application, for the convenience of description, a case where it is preheated to the first temperature or about the first temperature is taken as an example for explanation. However, those skilled in the art should understand that as long as the heating element is preheated to a temperature lower than the preset temperature, it is within the scope of the embodiments provided in this application. Of course, it is also possible to directly heat the heating element to a preset temperature through preheating when it is detected that the user is preparing to smoke, which is not limited here.

As shown in Figure 1, the heating control method of the above heating non-combustion smoking set specifically includes the following steps:

S101. Detect the motion parameters of the smoking set. In order to be able to determine whether the user is going to smoke, it is necessary to obtain the movement parameters of the smoking device itself, and process and analyze the movement parameters.

Specifically, the smoking device can continuously or periodically detect its own motion parameters. Among them, as long as the smoking device is connected to an external power source or provided with a built-in power source, it can detect its own motion parameters. It is not limited to detect the motion parameters after the user turns on the enable switch. Of course, in addition to the enable switch provided on the surface of the smoking device, enabling the detection function of the smoking device through the remote control device also belongs to the protection scope of the embodiments of the present application. The smoke can be pre-heated when the user smokes for the first time after the smoking set is charged, without the user turning on the enable switch of the smoking set. Of course, the detection can also be started after the user turns on the enable switch, which is not limited here.

Among them, the motion parameters are related to the actions that the user performs when preparing to smoke. For the convenience of description, the actions of the user when preparing to smoke are called target actions. For example, when the user is not ready to smoke, he usually puts the smoking utensil on the table or holds it in his hand. When preparing to smoke, move the smoking device to the vicinity of the mouth by hand. At this time, the smoking device will move a certain distance in the air at a corresponding speed while being held in hand. When the smoking set is picked up and placed near the mouth, it will also produce corresponding motion acceleration. In addition, when the smoking device is displaced in the air, it often does not move horizontally. Especially when the user hangs his arm and holds the smoking device, and moves the smoking device near the mouth, the smoking device will rotate in the air to generate an angular velocity. Therefore, the target action can be the action when the user holds the smoking device near the mouth, and the motion parameter can be the angular velocity when the smoking device rotates, and/or the acceleration in the motion state, and/or the smoking device in a short time Real-time displacement. In order to detect the angular velocity of the smoking device when it is rotating, a gyroscope can be preset in the smoking device, which can detect the angular velocity of the smoking device when it is rotating at any time, and send the detected angular velocity to the control unit. In order to detect its own acceleration, an acceleration sensor can be pre-installed in the smoking article, and the collected acceleration can be sent to the control unit at any time. In order to detect the real-time displacement distance of the smoking device, a displacement sensor can be set in advance, which can detect the real-time displacement distance of the smoking device at any time, and send the real-time displacement to the control unit. Among them, the control unit may be a processor with corresponding functions.

S102: Determine whether the current action is a target action according to the exercise parameter. After the processor receives each motion parameter, it can determine whether the user's current action is the target action through the acquired motion parameter. That is, it is determined whether the action currently performed by the user is an action performed to move the smoking article to the vicinity of the mouth for smoking.

Specifically, due to differences in the body structure and smoking habits of each person, the motion parameters corresponding to each person's actions when preparing to smoke are also different. Or when the user performs other actions while holding the smoking device, the smoking device will also generate corresponding motion parameters. To this end, the recognition model can be pre-trained, and the current movement of the smoking device can be confirmed through the recognition model and the collected movement parameters of the smoking device as a target action, that is, whether the current movement of the user is an action of preparing to smoke.

Among them, when training the recognition model, pre-selected the motion parameters corresponding to the smoking device when multiple users are preparing to smoke when the target actions are made, and when multiple users make actions such as raising their hands when they are not preparing to smoke, the smoking device The corresponding motion parameters are used as training samples. When collecting training samples of the target action, users of different genders, age groups, and smoking habits can be selected, and the sports parameters corresponding to the smoking devices when they are smoking are collected as training samples. Then the recognition model is trained through the training samples collected above. During training, exercise parameters are used as independent variables, and whether the user’s current action is the target action is the dependent variable. Among them, the algorithm in the recognition model can adopt, but is not limited to, decision trees, deep neural networks (Deep Neural Network, DNN), and Convolutional Neural Networks (Convolutional Neural Network, CNN), which will not be repeated here.

It should be noted that the above identification process can be performed locally by the processor of the smoking device itself, or after the processor transmits the collected motion parameters to the server through the wireless transmission module, the server feeds back the identification result to the processor.

S103: If the current action is the target action, trigger a pre-heating instruction and control the heating of the heating element of the smoking article based on the pre-heating instruction. After passing the judgment, if the user's current action is the target action, the pre-heating instruction is triggered to pre-heat the heating element of the smoking article.

Specifically, when the heating element is preheated, the heating element can be directly preheated to a preset temperature without reheating, so that the user can smoke. That is, when the smoking appliance detects that the user's current action is the target action, the heating element is directly heated to the preset temperature. However, since the judgment process cannot be 100% accurate, the user may make actions similar to smoking while holding the smoking device, which may easily lead to wrong judgments. For example, a user raises his hand while holding a smoking device, but he does not smoke, and he reaches out to take something, or raises his hand to touch his face or head. If the heating element is heated to the preset temperature at this time, it will easily cause harm to the user. Therefore, when preheating the heating element, the heating element can be preheated to the first temperature, or to about the first temperature, and then heated to the preset temperature when the smoking article detects the smoking action. Among them, the puffing action refers to the action when the user has placed the cigarette in the smoking set in the mouth and inhales. The detection of the user's smoking action can be determined by an airflow sensor arranged in the smoking device. When the airflow sensor detects airflow, it transmits the data to the processor. If the processor determines that the airflow is caused by the suction action, it heats the heating element to a preset temperature.

After the user completes a single smoking action, that is, after taking a puff, the heating of the heating element can be stopped under the control of the processor, and the temperature of the heating element will slowly return to the temperature when it was not heated. Or with extremely low power, the temperature of the heating element is maintained at the second temperature. And when the user prepares to smoke again, pre-heating is performed again to increase the temperature of the heating element to the first temperature or about the first temperature. Of course, the heat preservation instruction can also be triggered after the user completes a single smoking action, and the power is reduced based on the heat preservation instruction, so that the heating element is maintained at the first temperature or about the first temperature, and there is no need to check the user’s status again before the cigarette is finished. Whether the action is the target action, but after detecting the user's suction action, the heating element is heated to a preset temperature.

It should be noted that, in some of the above embodiments, the interpretation of the target action is that the action of moving the smoking device to the vicinity of the mouth by hand when the user is preparing to smoke, the main body is the action corresponding to the user. This action can also be understood as the action of the smoking device being moved to the vicinity of the mouth while the smoking device is in the hand when the user is preparing to smoke, the main body is the action corresponding to the smoking device. But in essence, whether the subject is the user or the smoking device, the meaning of the two is the same. Therefore, the target action can be understood as the action corresponding to the user, and can also be understood as the action corresponding to the smoking device, which is not limited here.
