[0029] The above drawings illustrate specific embodiments of the present application, which will be described in more detail below. These drawings and the textual description are not intended to limit the scope of the present application in any way, but rather to illustrate the concepts of the present application to those skilled in the art by reference to specific embodiments. DETAILED DESCRIPTION

[0030] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0031] Currently, atomizers typically heat the atomized matrix by controlling the heating element. Once the heating element reaches a target temperature, the atomized matrix on the heating element begins to atomize and produce smoke for the user to inhale. However, this method is prone to producing a burnt smell due to the prolonged heating of the atomized matrix, resulting in unsatisfactory puffing quality. Furthermore, in real life, atomizers typically only activate the heating element and heat the atomized matrix when they detect a user taking a puff. The long heating and baking time required to heat the atomized matrix from ambient temperature to the atomization temperature results in a slow smoke generation rate, affecting the user's puffing experience.

[0032] In response to the above problems, the embodiments of the present application provide a heating control method, device, and atomizer. By controlling the atomized matrix to move a first target length and a second target length during each puff, and the first target length and the second target length are both approximately equal to the length of the heating area of ​​the heating component, it is possible to avoid baking the atomized matrix in the same area for a long time, avoid the occurrence of burnt smell, and improve the puffing effect. At the same time, by strategically controlling the temperature of the heating component at different stages, it is possible to reduce the volume of the heating component, improve the heating efficiency of the heating component, and reduce the heating and baking time without affecting the heating effect of the atomized matrix, thereby achieving the characteristic of fast smoke generation speed.

[0033] The technical solution of the present application is described in detail below through specific embodiments. It should be noted that the following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0034] Figure 1A A schematic diagram of the structure of the atomizer provided in the embodiment of the present application is shown in FIG. Figure 1AAs shown, the atomizer includes two turntables (a first turntable 101 and a second turntable 102), and there is a long strip of transmission belt 1021 between the two turntables. The conveyor belt 1021 can be provided with an atomizing matrix (the atomizing matrix can be divided into a number of long strips of particle shapes and arranged in sequence on the conveyor belt 1021. The length of each particle-shaped atomizing matrix can be approximately equal to the length of the area to be heated or greater than the length of the area to be heated). Among them, a heating component can be set in a position area close to the conveyor belt 1021 (for example, a heating component is fixedly set below the conveyor belt 1021, so that a heating area can be formed above the heating component). When the second turntable 102 rotates, it drives the atomizing matrix on the conveyor belt 1021 to move toward the area to be heated, so that part of the atomizing matrix will enter the area to be heated. When the heating component heats the area to be heated and the temperature reaches the atomization temperature, the atomizing matrix in the area to be heated will be atomized to form smoke for the user to inhale. At the same time, while the second turntable 102 rotates, the first turntable 101 can also rotate at the same speed to release unheated atomized matrix, that is, the atomized matrix on the conveyor belt rolled into the first turntable 101 is not heated, while the atomized matrix on the conveyor belt rolled into the second turntable 102 is heated and inhaled by the user.

[0035] Figure 1B A schematic diagram of a heating scenario for an atomized substrate provided in an embodiment of the present application is shown in FIG. Figure 1B As shown, the atomizing matrix includes at least a heat-conducting layer 11 and a smoke-releasing layer 12. By controlling the heating element to heat up, the temperature of the atomizing matrix can be raised to the atomization temperature, thereby generating smoke. The length Wh of the heating element can be configured according to actual conditions. The smaller the heating element, the higher its heating efficiency, which can reduce the heating time of the atomizing matrix. Furthermore, during the heating process, the atomizing matrix can be moved in a certain direction, thereby preventing a certain portion of the atomizing matrix from being heated for a long time and preventing the occurrence of a burnt smell.

[0036] Figure 2 This is a flow chart of a heating control method provided in an embodiment of the present application. This method can be applied to an atomizer to control the heating of a heating component in the atomizer. The atomizer also includes a movable atomizing matrix. For example, refer to the above Figure 1A and Figure 1B The atomized substrate can be in the shape of a long strip, and part of the atomized substrate will be located in the area to be heated during the movement. The atomized substrate in the area to be heated can be heated by controlling the heating component to heat up. Figure 1B , the length of the area to be heated can be the length Wh of the heating assembly, and the total length of the atomized substrate is greater than the length Wh. Figure 2 As shown, the method includes the following steps:

[0037] In step S201 , in response to a puff trigger signal, the heating component is controlled to heat up to a target temperature range, and the atomized substrate is controlled to move a first target length toward the area to be heated, so that the atomized substrate in the area to be heated is atomized in the target temperature range and forms smoke.

[0038] In this embodiment, the puff trigger signal indicates that the user is ready to start puffing. In order to ensure the puffing effect, the heating component needs to heat the atomizing matrix and atomize it to form smoke. The atomizing matrix can be long and narrow, and the heating component can be set close to the atomizing matrix (for example, it can be set below the atomizing matrix. Smoke usually rises upwards, and setting it below can avoid obstructing the smoke generated after the atomizing matrix is ​​atomized). For example, continue to refer to the above Figure 1B The heating element can be placed under the long strip of atomizing substrate, while a heating area is formed above the heating element. The length of the heating area can be consistent with the length of the heating element. When the heating element heats up to the target temperature range, the atomizing substrate in the heating area will also be heated and atomized, forming smoke.

[0039] The movement of the atomized substrate can be controlled by configuring a conveyor belt. Specifically, the conveyor belt can be provided with an array of atomized substrates, which can be used for one or more puffs by the user. When the user puffs, the atomizer controls the movement of the atomized substrate on the conveyor belt by driving the conveyor belt.

[0040] In this embodiment, the first target length can be configured according to actual conditions. For example, referring to FIG1 above, the first target length can be configured according to the size length Wh of the heating component. Exemplarily, the first target length can be the size length Wh of the heating component, so as to ensure that the atomized matrix is ​​fully utilized. It can also be smaller than the size length Wh of the heating component, so that the amount of smoke generated by the atomized matrix during the heating process will be less. It can be specifically adjusted according to the user's smoking needs.

[0041] In step S202, after the preset conditions are met, the heating component is controlled to cool to below the target temperature range, and the atomized substrate is controlled to continue to move toward the area to be heated by a second target length, where the first target length and the second target length are both approximately equal to the length of the area to be heated. Of course, depending on different scenarios, the first target length and the second target length can also be longer than the pre-taken length to be heated or shorter than the length of the area to be heated.

[0042] In this embodiment, after the puff trigger signal triggers a response, the user typically begins to puff. Preset conditions can be configured. If the preset conditions are met during a puff, the heating component is no longer heated, allowing it to cool to below the target temperature range. Exemplary preset conditions may include puff duration, an end-of-puff trigger signal, an atomizer shutdown signal, and the like.

[0043] Among them, the target temperature range can be divided into two temperature ranges according to actual conditions, such as the insulation temperature range and the ambient temperature range. Among them, when the heating component is cooled to the insulation temperature range, the atomized matrix in the heating area can be kept warm. In this way, the next time the user continues to inhale, since the atomized matrix is ​​in an insulation state (that is, higher than the ambient temperature, but lower than the atomization temperature), the heating component takes less time to heat the atomized matrix to the target temperature range, which can increase the smoke-generating speed and ensure the smoking effect.

[0044] In addition, if the heating component cools down to the ambient temperature range (for example, because the atomizer shutdown signal triggers the heating component to cool down to the ambient temperature range), the atomized matrix in the heating area will no longer be heated. This situation is mainly suitable for situations where the user will not continue to inhale in a short period of time, so as to avoid the heating component being in the heating and heat preservation state for a long time and reduce energy consumption.

[0045] In this embodiment, controlling the movement of the atomized substrate by the second target length toward the heating area serves two purposes. First, residual heat remaining from the cooling of the heating assembly can be utilized to continue heating the atomized substrate in the heating area, thereby facilitating heat preservation of the atomized substrate in the heating area. Second, the atomized substrate previously in the heating area can be replaced, thereby avoiding prolonged heating of the atomized substrate in the heating area, which could produce a burning odor, and improving the suction effect.

[0046] In this embodiment, the atomized matrix can be divided into several units and then arranged in an array on a conveyor belt. This makes it more convenient to control the movement of the conveyor belt. When the conveyor belt transports the atomized matrix, the atomized matrix only moves one unit at a time. For example, the length of each unit can be the size length Wh of the heating component, that is, the first target length is one unit length, and the second target length is also one unit length.

[0047] The embodiment of the present application adopts a mobile atomizing matrix method for heating, which can ensure that the heated atomizing matrix is ​​fresh during each puff, and there is no problem of long-term heating of the atomizing matrix in the same area, which may cause a burnt smell. At the same time, by moving the atomizing matrix, the atomizing matrix newly moved to the area to be heated can be kept warm by utilizing the residual heat of the heating component, which can reduce the temperature rise time during the next puff, achieve rapid smoke generation, and improve the puffing effect. In addition, the use of a mobile heating atomizing matrix can miniaturize the heating component, making the heating component smaller, less self-absorbed heat, and faster heating. At the same time, it can expand the baking and heating area of ​​the atomizing matrix during each puff, thereby increasing the amount of aerosol released.

[0048] In some embodiments, Figure 3 A flow chart of a heating control method provided in another embodiment of the present application is shown as follows: Figure 3 As shown, the above method may further include the following steps: Step S301, heating the heating component, controlling the temperature of the heating component to be within the insulation temperature range, and the lower limit of the temperature of the insulation temperature range is at least higher than the ambient temperature. Step S302, obtaining the insulation time of the heating component in the insulation temperature range, and comparing the insulation time with the preset insulation threshold time. Step S303, if the insulation time is greater than or equal to the insulation threshold time, stopping heating the heating component. Step S201, in response to the suction trigger signal, controlling the heating component to heat up to the target temperature range, and controlling the atomized substrate to move to the first target length toward the area to be heated, and the atomized substrate in the area to be heated is atomized in the target temperature range and forms smoke. Step S202, after detecting that the preset conditions are met, controlling the heating component to cool down to below the target temperature range, and controlling the atomized substrate to continue to move to the area to be heated for a second target length, and the sum of the first target length and the second target length is greater than the length of the area to be heated.

[0049] In this embodiment, before the start of puffing (i.e., in response to a puff trigger signal), the heating component can be controlled to heat up to a holding temperature range. After the heating component heats up to the holding temperature range, the atomized substrate in the area to be heated can also begin to slowly heat up, eventually reaching the same temperature as the heating component. In this way, when the puff trigger signal is responded to, after the heating component continues to heat up to the target temperature range, the temperature rise time of the atomized substrate in the area to be heated can be reduced, thereby achieving rapid atomization of the atomized substrate and increasing the smoke production during puffing.

[0050] The heat preservation temperature interval is a temperature range including a lower limit and an upper limit. It is understood that the lower limit of the heat preservation temperature interval will be higher than the ambient temperature, and the upper limit will be lower than the lower limit of the target temperature interval, so as to achieve the purpose of heat preservation of the atomized substrate.

[0051] Furthermore, in one embodiment, the above-mentioned step S302 and step S303 may also be included. When the heating component is heated to the insulation temperature range and the atomized substrate in the heating area is preheated and kept warm, the user is ready to start puffing. If the user does not puff within the insulation threshold time, it is necessary to exit from the previous preparation state, stop heating the heating component, and no longer keep the atomized substrate in the heating area warm. This can prevent the heating component from being in the insulation temperature range for a long time, thereby increasing service life and reducing energy consumption.

[0052] Among them, after exiting from the previous standby state, the atomizer can be controlled to shut down. After the atomizer is shut down, it enters a state where it cannot be heated, and there are obvious prompts compared to the original power-on state (including but not limited to motor vibration, display changes, etc.).

[0053] The embodiment of the present application controls the heating component to be in the insulation temperature range, thereby increasing the starting temperature of the atomizer matrix and the heating component when the atomizer is started cold, so that the atomizer can quickly enter the working state after cold start, quickly heat up and generate smoke, and improve the smoking effect.

[0054] Based on the above embodiments, in some embodiments, Figure 4 A flow chart of a heating control method provided in another embodiment of the present application is shown as follows: Figure 4 As shown, this method is similar to the above embodiment. Figure 3 The difference is that it also includes step S401, controlling the atomized substrate to move a third target length toward the area to be heated, and the third target length is greater than or equal to the length of the area to be heated.

[0055] In this embodiment, before the atomizer draws its first puff, it is necessary to transfer a portion of the atomized substrate to the area to be heated. This ensures that the area is filled with atomized substrate that can be heated, thereby preventing the heating element from drying out. For example, if the length of the area to be heated is Wh, the length of the heating element to be moved is controlled to be W0 (W0 is greater than or equal to Wh).

[0056] Among them, the atomized substrate can be placed on a conveyor belt, and the atomized substrate can be driven to move by driving the conveyor belt. In addition, the conveying speed of the conveyor belt can be fixed, and the moving length of the atomized substrate can be controlled by the driving duration.

[0057] In this embodiment, before inhalation, in addition to the need to preheat the heating component, the atomized matrix also needs to be preheated. By transmitting part of the atomized matrix into the area to be heated, the atomized matrix can also enter the preheated state. During inhalation, the heating time can be reduced, the atomized matrix can be quickly atomized and smoked, and the inhalation effect can be improved.

[0058] In some embodiments, the above-mentioned step S202 can be specifically implemented by the following steps: when the puffing is completed or it is determined to be in the final stage of the puffing process, the heating component is controlled to cool down to below the target temperature range, and the puffing process is divided into at least an initial stage and a final stage according to the duration of the puffing.

[0059] In this embodiment, there is a corresponding trigger signal for the end of puffing. For example, when the user stops puffing, the air pressure will change, thereby indicating the end of puffing. For example, when the upper limit of puffing time is reached, the end of puffing is triggered, so that the atomizer detects the end of puffing.

[0060] In this embodiment, a standard average puff duration can be determined based on the duration of each puff taken by the user. For example, if the duration of three puffs taken by the user is 2.5 seconds, 3 seconds, and 3.5 seconds respectively, the average puff duration is 3 seconds. Based on this average puff duration, each puff process of the user can be divided into a beginning stage and a ending stage. For example, the beginning stage is from the start of the puff to 1.5 seconds, and the ending stage is from 1.5 seconds to 3 seconds.

[0061] Among them, when the atomizer detects that the puff has ended or is at the end of the puff process, if the user does not take the next puff in a short time, the heating component can stop heating, thereby allowing it to start cooling down slowly. After a period of time, its temperature will drop below the target temperature range.

[0062] Furthermore, when the atomizer detects that a puff has ended or is at the end of the puff process, it can reduce the heating power of the heating element, allowing it to continue heating, but keeping the temperature of the heating element no higher than the target temperature range, for example, keeping the temperature of the heating element in the insulation temperature range. When the temperature of the heating element is in the insulation temperature range, the atomized substrate in the heated area can be kept warm, ensuring a quick start if the user takes the next puff within a short period of time.

[0063] Furthermore, in some embodiments, the duration of the puff may be obtained and compared with a preset duration threshold; if the puff duration is greater than the preset duration threshold, it is determined that the puff process is currently at the end stage.

[0064] As mentioned above, a total puff duration average can be determined based on the total duration of each puff from the start to the end of the user's puff. In this embodiment, a timer can be started after the puff trigger signal is responded to, and the timed duration can be used as the puff duration. A preset duration threshold can then be set to determine whether the puff is currently at the end of the puff process.

[0065] For example, taking the average total puff duration as 3 seconds, the preset duration threshold can be configured as 1.5 seconds. When the puff trigger signal is responded to, the timing starts. If the timing duration (i.e., the puff duration mentioned in this embodiment) exceeds 1.5 seconds, it means that the current stage is at the end of the puff process.

[0066] The embodiment of the present application controls the heating component to cool down to below the target temperature range at the end of puffing or the end of the puffing process, and at the same time controls the atomized matrix to continue to move to the second target length toward the area to be heated. In this way, it can be ensured that the atomized matrix puffed in subsequent puffs is fresh and not heated, thereby improving the puffing effect.

[0067] In other embodiments, the above method may further include the following step: controlling the heating component to heat and keep the atomized substrate moved to the area to be heated warm.

[0068] In this embodiment, after the atomized substrate continues to move toward the heated area by the second target length, if the user still needs to continue smoking within a short period of time, the temperature of the heating component does not need to drop to the ambient temperature, that is, it continues to heat so that the atomized substrate can be kept warm within the insulation temperature range. In this way, the temperature rise time can be reduced during the next puff, thereby achieving rapid smoking.

[0069] On the basis of the above embodiment, the heating component may be controlled to stop heating and the atomizer may be controlled to shut down in response to a shutdown trigger signal.

[0070] In this embodiment, the atomizer can respond to a shutdown trigger signal at different time points and enter a shutdown state. The shutdown trigger signal may include but is not limited to a key press, a sliding cover, and other actions. When the atomizer enters a non-heating state after shutdown, there will be a clear indication relative to the original state (including but not limited to motor vibration, display change, etc.).

[0071] For example, Figure 5 The heating control timing diagram provided in the embodiment of the present application is as follows: Figure 5 As shown in the figure, during the operation of the atomizer, the heating component has a total of four different heating stages, namely A preheating, B insulation, C puff heating, and D cooling. The heating component's heating temperature varies in different stages. For example, in the insulation stage B, the heating component's temperature is maintained in the insulation temperature range, while in the puff heating stage C, the heating component's temperature is maintained in the target temperature range.

[0072] Among them, when the heating component is in different heating stages, the atomized matrix also has a corresponding movement sequence. Taking the length R1 as the size length of the heating component as an example, the length R2_1, length R2_2, and length R2_3 are all greater than the length R1.

[0073] The atomizer also includes two actions: power on and power off. Typically, the heating phase of the heating component occurs between these two actions. For example, a complete puffing process for a user might be power on, A preheating, B insulation, C puffing and heating, D cooling, and then power off. If a user requires multiple puffs, the order of the phases might be power on → A → B → C → D → B → C → D → B → C → D → B → ………………power off.

[0074] In this embodiment, powering on means that the atomizer detects a trigger signal (including but not limited to pressing a button, sliding the cover, etc.) in the off state and then powers on. After the atomizer is powered on, there are obvious prompts relative to the off state (including but not limited to motor vibration, display changes, etc.).

[0075] Among them, in a complete puffing process of the user, the A preheating stage is an optional configuration and is not a required stage, but the atomized matrix movement "R1" in this stage is required; if there is a significant temperature surge before "B insulation", it is considered that the "A preheating" stage exists.

[0076] "B Insulation" means that after the device is turned on, the heating element is maintained at a temperature significantly higher than the ambient temperature, but not high enough to cause significant aerosol formation in the smoke release layer. "B Insulation" acts as a pre-heating step for "C Puff Heating," reducing the temperature rise time during "C Puff Heating."

[0077] "D Cooling" refers to cooling or natural cooling after the puff is complete (including but not limited to when the air pressure signal returns or the puff limit time is reached), or in the latter stages of the puff. If cooling has already been performed during the "Puff Heating" stage, "D Cooling" may not be a required step in the user's complete puff process.

[0078] After "shutdown", the atomizer enters a non-heating state, and there are obvious prompts compared to the original state (including but not limited to motor vibration, display changes, etc.); "shutdown" is triggered when one of the following two situations occurs:

[0079] (1) During any of the stages “A Preheating, B Keeping Warm, C Pumping Heating, D Cooling”, a forced shutdown signal occurs (including but not limited to key presses, sliding the cover, etc.).

[0080] (2) In the "B insulation" stage, the "C suction heating" stage is not triggered and the duration reaches the set upper limit (for example, 60 seconds).

[0081] Among them, the movement of the atomized matrix "R1" usually occurs in the "A preheating" stage. Optionally, it can also start after the "shutdown" trigger, but in either case, it must be completed before the first "B insulation" stage after "starting up". In addition, the total distance moved by the atomized matrix during each puff is: the total distance moved during each puff is R2_1, R2_2, R2_3, ..., and each value of R2_1, R2_2, and R2_3 must be greater than Wh. In this way, the heating area of ​​the atomized matrix per puff can be greater than the area of ​​the heating component, thereby increasing the aerosol release per puff.

[0082] For example, assuming the length of the heating element is 5 mm, the atomized matrix moves 5 mm each time the user takes a puff, and the atomized matrix is ​​always in the baking state of the heating element during the movement. Specifically, the following two steps may be involved:

[0083] 1. After the user turns on the device, the heating component begins to heat and the atomized matrix begins to move. At this time, the heating temperature of the heating component is lower than the atomization temperature of the atomized matrix, and the distance the atomized matrix moves is roughly equal to the size of the heating component in the direction of movement of the atomized matrix (hereinafter referred to as one unit). When it is detected that the user has started to puff, in the first half of a puff, the temperature of the heating component is raised to the temperature at which the atomized matrix is ​​atomized, and the atomized matrix moves one unit. In the second half of a puff, the temperature of the heating component drops below the atomization temperature of the atomized matrix, and the atomized matrix moves one unit.

[0084] 2. During the puffing process, assuming a user takes 3 seconds to puff, the heating component moves 5mm during the first 1.5 seconds of heating and 5mm during the last 1.5 seconds of heating, meaning one puff results in two movements. The temperature of the heating component during the first 1.5 seconds of movement is higher than during the last 1.5 seconds of movement. The temperature of the heating component during the first 1.5 seconds of movement should be sufficient to atomize the atomizing matrix. During the last 1.5 seconds of movement, the temperature of the heating component should be lower than the atomization temperature of the atomizing matrix, i.e., the insulation temperature. During the last 1.5 seconds of movement, the residual temperature from the first 1.5 seconds of movement is used to preheat the atomizing matrix for the next puff, resulting in faster initiation of smoke on the next puff.

[0085] The embodiment of the present application can increase the starting temperature of the "puff heating C" stage through the "B insulation" stage, reduce the time from temperature rise to aerosol release, and achieve rapid smoking. In addition, the use of mobile heating can expand the baking area of ​​the atomized matrix per unit number of puffs while miniaturizing the design of the heating component (less self-absorption of heat, fast heating), increase the amount of aerosol released, and avoid the burnt smell caused by long-term heating in the same area. At the same time, the "A preheating" stage can increase the initial temperature of the atomized matrix and the heating element in the cold start state, so that after the cold machine is started, it can enter a state where it can quickly heat up and smoke. The "atomized matrix movement R1" can ensure that the atomized matrix of each puff is fresh and has not been heated. Finally, "D cooling" can ensure that when the atomized matrix moves to the next puff, the atomized matrix of the next puff will not be baked at high temperature in advance, resulting in aerosol loss.
