Description

Technical Field

[0001] The present invention relates to the field of aerosol generating device control methods, and in particular to a heating and cleaning control method for an aerosol generating device, a heating and cleaning control device for an aerosol generating device, an electronic device and a computer-readable storage medium. Background Art

[0002] As people pay more and more attention to health, they realize that traditional cigarettes are harmful to health. Therefore, new tobacco products have emerged, such as heat-not-burn cigarettes. Compared with traditional cigarettes, heat-not-burn cigarettes reduce harmful substances such as tar and carbon monoxide brought by traditional cigarettes while meeting the physiological needs of users. Heat-not-burn cigarettes heat the tobacco in the aerosol generating matrix to release aerosols, so that users can get a smoking experience. The tobacco is not burned, so no complex chemical reactions are produced, allowing users to get the experience while reducing the inhalation of harmful substances. Heat-not-burn cigarettes can usually be heated by heating the inner core to generate aerosols for users to smoke.

[0003] However, during the use of the inner core heating non-combustion appliance, the surface of the heating element is in contact with tobacco or herbal substances. Under long-term high-temperature working conditions, tobacco or herbal substances are easily sintered on the surface of the heating element, causing a burnt smell. Sintered materials remain on the surface of the heating element, and the sintered materials will gradually increase with repeated uses, causing abnormal temperature detection problems. At the same time, the accumulated residue will absorb a large amount of condensation, causing liquid to invade the circuit space and corrode circuit components.

[0004] In the prior art, in order to remove the above-mentioned residual sintered materials, a high temperature higher than the normal heating temperature of the cigarette is usually used for cleaning. The continuous high temperature requires the battery to discharge at a high rate for a long time. At the same time, the components installed on the heating needles also need to withstand high temperatures. Under repeated thermal shocks, there is a risk of deformation and cracking. Continuous high temperatures will cause damage to the heating needles and related components. Summary of the invention

[0049] The following specific embodiments illustrate the implementation of the present invention, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. Although the description of the present invention will be introduced in conjunction with the preferred embodiment, this does not mean that the features of this invention are limited to this implementation. On the contrary, the purpose of introducing the invention in conjunction with the implementation is to cover other options or modifications that may extend based on the claims of the present invention. In order to provide a deep understanding of the present invention, the following description will include many specific details. The present invention can also be implemented without using these details. In addition, in order to avoid confusion or blurring the focus of the present invention, some specific details will be omitted in the description. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0050] It should be noted that in this specification, similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined and explained in the subsequent drawings.

[0051] The terms “first”, “second”, etc. are only used for distinguishing descriptions and should not be understood as indicating or implying relative importance.

[0052] The term "aerosol generating article" includes an aerosol generating substrate, which is a material that can provide volatile components when heated. The aerosol generating substrate can be solid or liquid. For example, a liquid aerosol generating substrate can contain water, solvents, ethanol, plant extracts and natural or artificial flavorings. The aerosol generating substrate can also be a pasty material, a porous material pouch comprising an aerosol generating substrate or, for example, loose tobacco mixed with a gelling agent or adhesive, which can contain common atomizers such as glycerol. Alternatively, the aerosol generating substrate can include tobacco-containing materials or non-tobacco materials, or it can contain tobacco materials and non-tobacco materials. Non-tobacco materials, for example, spices that can be volatilized by heating or non-heating, can contain or may not contain nicotine. Tobacco materials, for example, can include one or more of tobacco, tobacco derivatives, expanded tobacco, reconstituted tobacco or tobacco substitutes. Atomizers, such as glycerine or propylene glycol, are also included in the aerosol generating substrate. The aerosol generating substrate can also include additionally added ingredients, such as nicotine or spice extracts. For the solid aerosol generating substrate, it can be formed into a cigarette cartridge or a cigarette stick structure contained in a smoking device, and further made into a heated cigarette, which also includes a tobacco substrate part and a filter part.

[0053] In order to make the objectives, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0054] The inventors have discovered that during daily use of the inner core heating cigarette device, the surface of the heating element will come into contact with the aerosol generating substrate, and the highest operating temperature range when the heating element heats the aerosol generating substrate can usually reach 350-420°C, and this temperature range is usually maintained for 15-20s. At this temperature, the aerosol generating substrate can quickly generate volatile aerosols. However, under this temperature state, there will be residual substances on the surface of the heating element, adhering to the surface in a charred state. On the one hand, the above-mentioned residual substances affect the taste, and on the other hand, they are prone to health risks under repeated heating. Since the heating area is generally concentrated in the length direction of the heating element, relative to the distal area of ​​the lead solder pin, refer to Fig. 9 For example, the heating element is arranged on the flange seat D, and the heating area of ​​the heating element includes the sub-high temperature zone A, the high temperature zone B and the relatively low temperature zone C. Therefore, the main carbon deposit residues on the heating element are also concentrated in the high temperature zone B and the sub-high temperature zone A.

[0055] The inventors have carefully studied the prior art and found that in order to remove the above-mentioned residues on the surface of the heating element, the prior art usually discharges the battery at a high rate, causing the temperature of the heating element to rise to about 500°C, and then removes and volatilizes the residual substances at high temperature for about 30-60 seconds. In this process, the flange seat D of the heating element will transfer heat to the heating element, and the temperature of the flange seat D will rise to about 280°C. The fixed base connected to the flange seat D will be subjected to great heat resistance pressure, and the PEEK material currently used in the fixed base of the heating element has a conventional temperature resistance of about 260°C. Long-term high-temperature operation and large temperature difference thermal shock are prone to deformation, accelerated aging, and shortened service life. In addition, heating and cleaning require battery power. The heating devices in the prior art all use batteries with rate discharge capabilities. Normally, the heating and cleaning in the prior art requires the battery to be able to release a current of about 5A-7A to raise the heating element to about 500°C and maintain it for 30-60s. This has very high discharge requirements on the battery, and the battery will experience long-term high-rate discharge, which has a negative impact on the battery life and safety of use, causing loss of battery life and posing risks to the safety of battery use.

[0056] First, reference Figure 1 The embodiment of the present invention discloses a heating cleaning control method of an aerosol generating device, wherein the aerosol generating device includes a heating component, and the heating component is used to heat the aerosol generating product. The heating cleaning control method includes:

[0057] S1: Self-cleaning heating: After heating the aerosol-generating product, the heating component is controlled to be heated to a heating and cleaning temperature, and maintained for a predetermined heating and cleaning time to clean the heating component.

[0058] The aerosol generating device heats the aerosol generating article by heating the heating component to the maximum operating temperature and maintaining the temperature for a specific heating time. The maximum operating temperature is the highest temperature during the heating process of the heating component, wherein the heating process refers to the process of heating the aerosol generating article to generate an aerosol. The specific heating time is the time during which the heating component is maintained at the maximum operating temperature, the heating cleaning temperature is the maximum operating temperature, and the predetermined heating cleaning time is longer than the specific heating time.

[0059] By adopting the method in the above embodiment, the heating cleaning control method of the present invention controls the temperature of the heating component during heating cleaning so that the heating cleaning temperature is the same as the maximum temperature of the heating component when heating the aerosol generating product, thereby avoiding the use of excessively high temperatures during the heating cleaning process, thereby reducing the negative impact of long-term high temperature on the heating component and the battery that controls the heating cleaning.

[0060] For example, reference Fig.10 and Fig.11 , Fig.10 For heating components after long-term use, Fig.11 For the heating parts that have been heated and cleaned for 3 minutes, Fig.11 The carbon deposit residue on the heating component is significantly reduced, which shows the effectiveness of the heating cleaning control method of the present invention.

[0061] Since the highest temperature of the heating component during the heating process is usually 250-450° C., the heating cleaning temperature is set to 250-450° C. The predetermined heating cleaning time may be 10-300 seconds.

[0062] Furthermore, the specific heating time for heating the aerosol generating article during the heating process of the heating component is usually 5-20 seconds. In the present invention, the lower limit of the predetermined heating and cleaning time can be 25-30 seconds, and the upper limit can be 10 minutes. A longer time is conducive to more thorough heating and cleaning.

[0063] Preferably, the predetermined heating and cleaning time is within the range of 40-120 seconds, which can ensure effective heating and cleaning of the heating component while being short in time, thus avoiding the user having to wait too long.

[0064] Controlling the heating component to heat up to the heating and cleaning temperature in step S1 may be a stepwise heating, specifically including:

[0065] The heating component is controlled to increase the temperature to the heating and cleaning temperature through at least one step-by-step temperature increase stage.

[0066] In the at least one step-wise temperature increase stage, the heating component is controlled to gradually increase the temperature from the first temperature to the second temperature, and maintain the second temperature for a predetermined duration.

[0067] The process of gradually increasing the temperature from the first temperature to the second temperature is a slow temperature increase process, not a sudden change from the first temperature to the second temperature.

[0068] Specifically, in the step-by-step heating process, for example, the heating component first rises from room temperature to T1, and is maintained at T1 for a period of time t1 (i.e., in the first step-by-step heating stage, the first temperature is room temperature, the second temperature is T1, and the predetermined duration is the duration t1 during which the heating component is maintained at the second temperature T1). Subsequently, in the next step-by-step heating stage, the temperature of the heating component gradually rises from T1 to T2, and is maintained at T2 for a period of time t2 (i.e., in the second step-by-step heating stage, the first temperature is T1, the second temperature is T2, and the predetermined duration is t2), and so on, until it rises to the heating and cleaning temperature.

[0069] After the heating component maintains the predetermined heating and cleaning time at the heating and cleaning temperature, the heating component gradually cools down, and the entire heating curve shows a trend of first rising and then falling. The highest operating temperature is the highest second temperature. Preferably, the heating and cleaning temperature occurs in the first half of the heating process of the entire heating curve. That is, in the step-by-step heating process of controlling the heating component to heat up to the heating and cleaning temperature in step S1, the specific control heating component is heated to the heating and cleaning temperature through no more than three of the above-mentioned step-by-step heating stages. More specifically, the heating component can be heated to the heating and cleaning temperature through only one step-by-step heating stage. In another embodiment, the heating component can be heated to the heating and cleaning temperature through two step-by-step heating stages. In yet another embodiment, the heating component can be heated to the heating and cleaning temperature through three step-by-step heating stages. By controlling the heating component to rise to the heating and cleaning temperature in the first half of the entire heating curve, especially the heating and cleaning temperature can be reached after only three steps at most, it is helpful to quickly start the heating and cleaning of the heating component, prevent the user from waiting too long, and improve the user experience.

[0070] Further, refer to Figure 2 , the heating cleaning control method may include the following steps:

[0071] S0: Detection: When it is detected that the aerosol generating device is connected to an external power source, the self-cleaning heating is turned on, and the self-cleaning heating is performed by the external power source, wherein the external power source is used to charge the aerosol generating device.

[0072] In the prior art, the self-cleaning heating of the heating component is usually performed by the battery in the aerosol generating device, and whether to turn on the self-cleaning heating is implemented by the user. The frequency of self-cleaning heating is difficult to limit, and the battery inside the device is greatly damaged.

[0073] In this embodiment, an external power source is used to perform self-cleaning heating on the heating component. At this time, the current required for the heat generated by the self-cleaning heating of the heating component comes from the external power source (that is, the external power source directly powers the heating component). The battery in the aerosol generating device does not discharge during the heating and cleaning process. Therefore, the battery in the aerosol generating device will not produce life loss and safety risks due to long-term high-rate discharge, which helps to protect the battery in the aerosol generating device and extend its service life.

[0074] In other embodiments, the external power supply can charge the battery in the aerosol generating device while heating and cleaning the heating component of the aerosol generating device. In this way, heating and cleaning can be performed while charging is performed, thereby improving the efficiency of self-cleaning heating and charging. Insulating materials, detection units, alarm units and other safety-related components can also be additionally provided to improve the safety of simultaneous self-cleaning heating and charging.

[0075] Preferably, during the self-cleaning heating of the heating component of the aerosol generating device, the battery in the aerosol generating device is neither charged nor discharged. During the self-cleaning heating process, the temperature of the heating component is relatively high. During the charging process, the battery in the aerosol generating device may also heat up. The high-temperature heating component and the heated battery may affect each other, posing a safety risk. In addition, since the self-cleaning heating and charging of the battery in the aerosol generating device are performed at the same time, the external power supply may consume a large amount of power and may also generate heat, damaging the external power supply and reducing the service life of the external power supply, which also poses a safety risk. By separating the self-cleaning heating process from the charging process, it helps to improve the safety of use without setting up other additional components.

[0076] The external power supply can be a dedicated adapter device, or a power bank or similar energy storage device with current release capability. The discharge current of the adapter or energy storage device shall not be less than 0.5A and shall not exceed 16A. The voltage shall not be less than 2V and shall not exceed 36V. The current and voltage of the external power supply are controllable and can be output stably. Usually, when performing self-cleaning heating, the voltage of the external power supply can be 5V and the current can be 2A.

[0077] S1: Self-cleaning heating: After heating the aerosol-generating product, the heating component is controlled to be heated to a heating and cleaning temperature, and maintained for a predetermined heating and cleaning time to clean the heating component.

[0078] Among them, after the self-cleaning heating is completed, the aerosol generating device can be charged by an external power supply.

[0079] In the above embodiments, reference Figure 3 , step S0 may include the following steps:

[0080] S01: When it is detected that the aerosol generating device is connected to an external power source, the self-cleaning heating is automatically turned on.

[0081] Automatically controlling self-cleaning heating can reduce user operations and help improve user experience.

[0082] In another embodiment, reference Figure 4 , step S0 may include the following steps:

[0083] S02: When it is detected that the aerosol generating device is connected to an external power source, a heating and cleaning prompt is issued.

[0084] Specifically, when the aerosol generating device is connected to an external power source, the control unit in the aerosol generating device can recognize that there is current input from the external power source, and by controlling the electronic switch, a heating and cleaning prompt can be given before the circuit is connected.

[0085] S021: Determine whether the heating and cleaning prompt is responded to.

[0086] S022: If the heating and cleaning prompt is responded to, the external power supply performs self-cleaning heating on the heating component.

[0087] Specifically, the connection between the external power supply and the aerosol generating device is a manual operation, and the generated heating and cleaning prompt can be easily recognized by the user. If the user decides to clean the heating component, the operation confirmation can be performed, that is, the heating and cleaning prompt is responded to, and the self-cleaning heating is turned on. The specific cleaning process refers to the aforementioned step S1.

[0088] S023: If the heating and cleaning prompt is not responded to, the external power supply does not perform self-cleaning heating on the heating component, and the external power supply charges the aerosol generating device.

[0089] The user may also choose not to clean the heating component, in which case the aerosol generating device may be charged directly via an external power source.

[0090] In the above embodiment, the heating and cleaning prompt includes at least one of the following: light prompt, vibration prompt, screen display prompt. Specifically, after the external power supply is plugged in, the prompt method can be light, screen information, vibration, etc., so that the user can perceive the heating and cleaning prompt.

[0091] Furthermore, the heating and cleaning prompt can be canceled in one of the following ways: canceled by screen input, canceled by password input, canceled by key action, and canceled by external power access action. Cancellation by screen input may include, for example, screen clicks and slides; cancellation by password input may include, for example, symbol passwords, sliding pattern passwords, etc.; cancellation by key action may include, for example, one or more key actions within the prompt time. In the cancellation by external power access action, the specific cancellation method may be, for example: displaying a heating and cleaning prompt when the external power supply is connected to the aerosol generating device, when the heating and cleaning prompt appears, the user removes the external power supply, disconnects the external power supply from the aerosol generating device, and then reconnects the external power supply to the aerosol generating device within a preset time, at which time the self-cleaning heating process is skipped, and the external power supply directly charges the aerosol generating device (the preset time may be, for example, 5 seconds, that is, when the external power supply is connected and the heating and cleaning prompt appears, the user removes the external power supply, and reconnects the aerosol generating device to the external power supply within 5 seconds after removal, and the external power supply directly starts charging, and no heating and cleaning prompt is issued, and no self-cleaning heating is performed on the heating component).

[0092] In another embodiment, reference Figure 5 , the aerosol generating device can communicate with the terminal device, and step S0 may include the following steps:

[0093] S03: When it is detected that the aerosol generating device is connected to an external power source, the aerosol generating device sends a connection signal to the terminal device, and the aerosol generating device receives a heating and cleaning instruction from the terminal device and starts self-cleaning heating.

[0094] Specifically, the aerosol generating device can be associated with the terminal device through wired or wireless means to connect and communicate. The wireless means can be, for example, Bluetooth, so that the user can use the terminal device to operate whether to perform self-cleaning heating on the heating component of the aerosol generating device, which helps to improve the user experience.

[0095] Furthermore, the aerosol generating device and / or terminal device may allow the developer mode to be enabled. After unlocking the internal control software, the user can independently choose to perform self-cleaning and heating in manual or automatic mode. The developer mode may include, for example, obtaining the corresponding self-cleaning and heating permissions after the user authenticates himself; unlocking and personalizing the aerosol generating device and / or terminal device using dedicated equipment at the point of sale; and remotely enabling the aerosol generating device and / or terminal device through the APP software.

[0096] In other embodiments, reference Figure 6 , the heating cleaning control method may include the following steps:

[0097] S0: Detection: When it is detected that the aerosol generating device is connected to an external power source, the self-cleaning heating is turned on, and the self-cleaning heating is performed by the external power source, wherein the external power source is used to charge the aerosol generating device.

[0098] S1: Self-cleaning heating: After heating the aerosol-generating product, the heating component is controlled to be heated to a heating and cleaning temperature, and maintained for a predetermined heating and cleaning time to clean the heating component.

[0099] S2: Charging: After the self-cleaning heating of the heating component is completed, the external power supply charges the aerosol generating device.

[0100] The number of aerosol generating products that can be inhaled by the aerosol generating device after one charge and before the next charge is limited, and there will be a certain amount of carbon deposit residue on the heating component. In the above manner, since the external power supply is used to charge the aerosol generating device, by binding the charging with the self-cleaning heating, each time charging is performed, a self-cleaning heating is performed first, and then charging is performed automatically after completion. Since charging is a high-frequency action, the heating component can be forced to perform self-cleaning heating on a regular basis at a high frequency, so that the amount of carbon deposit residue on the heating component each time can be controlled, and it will not be difficult to clean due to increasing accumulation, which helps to protect the heating component, reduce damage to the heating component, and extend the service life of the heating component. After the heating and cleaning is completed, it can automatically switch to charging until the charging is completed.

[0101] Among them, in each of the above embodiments, an electronic switch may be provided. When an external power source is connected to the aerosol generating device, the heating circuit and the charging and discharging circuit are not connected first. When it is confirmed that the self-cleaning heating is turned on, the electronic switch controls the current input by the external power source to directly enter the heating component through the heating circuit inside the aerosol generating device. At this time, the battery and the charging and discharging circuit of the aerosol generating device are in a disconnected state, and the temperature control and detection circuit and the temperature protection circuit of the heating component are in a working state, which plays a role in monitoring and protecting the temperature of the heating component. The temperature control and detection circuit and the temperature protection circuit of the battery of the aerosol generating device can be disconnected or turned on. When turned on, the internal battery can be monitored to avoid accidents and improve the reliability of the entire device.

[0102] When the self-cleaning heating is completed, the heating circuit of the heating component is disconnected, and the battery and the charging and discharging circuit of the aerosol generating device are switched to working state and charging begins. During the charging process, the temperature control and detection circuit and the temperature protection circuit of the battery of the aerosol generating device remain in working state to monitor and protect the temperature of the internal battery. When charging, the heating component is cooled down simultaneously. Since the heating circuit has been disconnected before charging begins, the heating component will cool down immediately, and the temperature is no longer hundreds of degrees high. Therefore, there will not be a large amount of heat, and charging will not be affected. The temperature control and detection circuit and the temperature protection circuit of the heating component can be disconnected or remain in working state. If they remain in working state, the temperature of the heating component can continue to be monitored and protected to avoid accidents. After the heating circuit is disconnected, the cooling rate of the heating component depends on the ambient temperature.

[0110] By adopting the above technical solution, the electronic device controls the temperature of the heating component during heating and cleaning so that the heating and cleaning temperature is the same as the maximum temperature of the heating component when heating the aerosol generating product, thereby avoiding the use of excessively high temperatures during the heating and cleaning process, thereby reducing the negative impact of long-term high temperature on the heating component and the battery that controls the heating and cleaning.

[0111] In a fourth aspect, an embodiment of the present invention discloses a computer-readable storage medium, in which at least one instruction is stored. When the at least one instruction is executed, the heating and cleaning control method in any of the aforementioned embodiments is implemented.

[0112] By adopting the above technical solution, the computer-readable storage medium controls the temperature of the heating component during heating and cleaning so that the heating and cleaning temperature is the same as the maximum temperature of the heating component when heating the aerosol generating product, thereby avoiding the use of excessively high temperatures during the heating and cleaning process, thereby reducing the negative impact of long-term high temperature on the heating component and the battery that controls the heating and cleaning.
