DETAILED DESCRIPTION

[0030] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0031] At present, when the atomizer heats the atomized matrix, it usually controls the heating component to heat up. When the temperature of the heating component rises to a certain target temperature, the atomized matrix on the heating component is heated and begins to atomize to produce smoke for the user to inhale. However, due to the long-term heating of the atomized matrix, this method is prone to burnt smell and the suction effect is not ideal. In addition, in real life, the atomizer usually starts working when the user detects the user's inhalation. The heating component starts to work and heats the atomized matrix. It takes a long time to heat the atomized matrix from the ambient temperature to the atomization temperature, resulting in a slow smoke-generating speed of the atomized matrix, which affects the user's smoking experience.

[0032] In response to the above problems, the embodiments of the present application provide a heating control method, device and atomizer, which control the atomized matrix to move a first target length and a second target length each time the atomized matrix is ​​puffed, and the first target length and the second target length are approximately equal to the length of the heating area of ​​the heating component, thereby avoiding long-term baking of the atomized matrix in the same area, avoiding the occurrence of burnt smell, and improving the puffing effect. At the same time, by strategically controlling the temperature of the heating component at different stages, the volume of the heating component can be reduced without affecting the heating effect of the atomized matrix, the heating efficiency of the heating component can be improved, the heating baking time can be reduced, and the characteristic of fast smoke generation speed can be achieved.

[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 atomized matrix (the atomized 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 atomized 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 atomized matrix on the conveyor belt 1021 to move toward the area to be heated, so that part of the atomized 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 atomized matrix in the area to be heated will be atomized to form smoke for the user to inhale. At the same time, when 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 of an atomized substrate provided in an embodiment of the present application, such as Figure 1B As shown, the atomizing matrix at least includes a heat-conducting layer 11 and a smoke-releasing layer 12. By controlling the heating component to heat up, the temperature of the atomizing matrix can be raised to the atomizing temperature to generate smoke. Among them, the length Wh of the heating component can be configured according to actual conditions. The smaller the size of the heating component, the higher its heating efficiency, which can reduce the heating and baking time of the atomizing matrix. At the same time, during the heating process of the atomizing matrix, it can move in a certain direction, so as to avoid a certain piece of the atomizing matrix from being heated and baked for a long time and avoid the appearance of a burnt smell.

[0036] Figure 2 The schematic diagram of the heating control method provided in the embodiment of the present application is a flow chart. The method can be applied to an atomizer to control the heating of the heating component in the atomizer. The atomizer also includes a movable atomizing substrate. For example, refer to the above Figure 1A and Figure 1B The atomized substrate may be in the shape of a long strip, and part of the atomized substrate may be located in the area to be heated during the movement, and the atomized substrate located in the area to be heated may 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 comprises the following steps:

[0037] Step S201, in response to the suction trigger signal, controls the heating component to heat up to a target temperature range, and controls the atomized substrate to move a 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 to form smoke.

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

[0039] The movement of the atomized substrate can be controlled by configuring a conveyor belt. Specifically, an array of atomized substrates can be provided on the conveyor belt, 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 FIG. 1 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] Step S202, after the preset conditions are met, the heating component is controlled to cool down to below the target temperature range, and the atomized substrate is controlled to continue to move to the area to be heated by a second target length, and the first target length and the second target length are both approximately equal to the length of the area to be heated. Of course, 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 according to different scenarios.

[0042] In this embodiment, after the puff trigger signal triggers the response, the user usually starts to puff, and a preset condition can be configured. If the preset condition is met during the puff, the heating component is no longer heated to cool it down to below the target temperature range. Exemplarily, the preset condition can be the puff duration, the puff end trigger signal, the atomizer shutdown signal, etc.

[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 a heat preservation 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, thereby increasing the smoke-generating speed and ensuring the smoking effect.

[0044] In addition, if the heating component is cooled down to the ambient temperature range (for example, 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 a heating and heat preservation state for a long time and reduce energy consumption.

[0045] In this embodiment, the purpose of controlling the atomized substrate to move to the area to be heated by the second target length is twofold: on the one hand, the residual heat existing when the heating component is cooled down can be used to continue heating the atomized substrate in the area to be heated, and it is also convenient to keep the atomized substrate in the area to be heated warm. On the other hand, the atomized substrate originally in the area to be heated can be updated and replaced, avoiding long-term heating of the atomized substrate originally in the area to be heated, generating a burnt smell, 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 moves only 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 heats by moving the atomized substrate, which can ensure that the heated atomized substrate is fresh each time you draw, and there is no problem of long-term heating of the atomized substrate in the same area, which may cause a burnt smell. At the same time, by moving the atomized substrate, the atomized substrate newly moved to the area to be heated can be kept warm by the residual heat of the heating component, which can reduce the temperature rise time during the next draw, achieve rapid smoke generation, and improve the draw effect. In addition, by using a mobile heating atomized substrate, the heating component can be miniaturized, making the heating component smaller in size, less self-absorbed heat, and faster in heating. At the same time, it can expand the baking and heating area of ​​the atomized substrate during each draw, thereby increasing the amount of aerosol released.

[0048] In some embodiments, Figure 3 A schematic diagram of a heating control method according to another embodiment of the present application is shown in FIG. Figure 3 As shown, the above method may also include the following steps: Step S301, heating the heating component, controlling the temperature of the heating component to be in the insulation temperature interval, and the lower limit of the temperature of the insulation temperature interval is at least higher than the ambient temperature. Step S302, obtaining the insulation time of the heating component in the insulation temperature interval, 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, stop heating the heating component. Step S201, in response to the suction trigger signal, control the heating component to heat up to the target temperature interval, and control the atomized substrate to move the first target length to the area to be heated, and the atomized substrate in the area to be heated is atomized in the target temperature interval and forms smoke. Step S202, after detecting that the preset conditions are met, control the heating component to cool down to below the target temperature interval, and control the atomized substrate to continue to move the second target length to the area to be heated, 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 the puff trigger signal), the heating component can be controlled to heat up to the insulation temperature range. After the heating component is heated to the insulation temperature range, the atomized substrate in the area to be heated can also start to slowly heat up, and finally reach the same temperature as the heating component. In this way, when the corresponding puff trigger signal is issued, 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, the atomized substrate can be quickly atomized, and the smoke generation amount during puffing can be increased.

[0050] The insulation temperature interval is a temperature range including a lower limit and an upper limit. It is understood that the lower limit of the insulation 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, the atomized substrate in the heating area is preheated and kept warm, and the user is ready to start inhaling. If the user does not inhale within the insulation threshold time, it is necessary to exit from the previous preparation state, stop the heating component from heating, and no longer keep the atomized substrate in the heating area warm. This can avoid the heating component being in the insulation temperature range for a long time, thereby increasing the service life and reducing energy consumption.

[0052] Among them, after exiting from the previous preparation 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 cold started, 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 one in 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 the first puff, part of the atomized substrate needs to be transferred to the area to be heated, that is, by moving the atomized substrate toward the area to be heated, it is ensured that there is atomized substrate that can be heated in the area to be heated, so as to avoid dry burning of the heating component. Exemplarily, the length of the area to be heated is the length of the heating component Wh, and the length of the atomized substrate movement needs to be 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 then the moving length of the atomized substrate can be controlled by the driving duration.

[0057] In this embodiment, before inhalation, in addition to the preheating of 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 preheating 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 step S202 can be specifically implemented by the following steps: when the puffing is finished 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 a head 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 changes, thereby indicating the end of puffing. For example, when the upper limit of the 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 according to the duration of each puff of the user. For example, if the duration of three puffs of the user is 2.5 seconds, 3 seconds, and 3.5 seconds respectively, the average puff duration is 3 seconds. Based on the average puff duration, each puff process of the user can be divided into a head stage and a tail stage. For example, the head stage is from the start of the puff to 1.5 seconds of timing, and the tail stage is from 1.5 seconds to 3 seconds of timing.

[0061] Among them, when the atomizer detects that the puffing is over or is at the end stage of the puffing process, if the user does not take the next puff in a short time, the heating component can stop heating, so that it can start to cool down slowly, and after a period of time, its temperature will drop below the target temperature range.

[0062] Furthermore, when the atomizer detects that the puffing is finished or is at the end of the puffing process, the heating power of the heating component can be reduced to allow it to continue to heat, but the temperature of the heating component is no longer higher than the target temperature range, for example, the temperature of the heating component is kept in the insulation temperature range. When the temperature of the heating component is in the insulation temperature range, the atomized substrate in the heated area can be kept warm, and if the user continues to puff in a short time, quick smoking can be guaranteed.

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

[0064] It is mentioned above that a total puff duration average can be determined based on the total puff duration from the start of each puff to the end of the puff. In this embodiment, the timing can be started after the puff trigger signal is responded to, the timing duration is used as the puff duration, and then a preset duration threshold is set to determine whether the current stage is at the end of the puff process.

[0065] For example, taking the total average duration of puffing 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 puffing 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 in the final stage of the puffing process, and at the same time controls the atomized matrix to continue to move to the heating area by a second target length. This ensures that during subsequent puffing, the atomized matrix puffed is fresh and has not been 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 to the heated area by the second target length, if the user still needs to continue inhaling 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 inhalation, thereby achieving rapid smoke generation.

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

[0070] In this embodiment, the atomizer can respond to the shutdown trigger signal at each different time point and enter the shutdown state. The shutdown trigger signal may include but is not limited to actions such as pressing a button and sliding a cover. When the atomizer enters a non-heatable state after shutdown, there is an obvious prompt relative to the original state (including but not limited to motor vibration, display change, etc.).

[0071] For example, Figure 5 A schematic diagram of the heating control timing provided in the embodiment of the present application is shown in FIG. Figure 5 As shown, during the operation of the atomizer, the heating component includes 4 different heating stages, namely A preheating, B heat preservation, C suction heating, and D cooling. The heating temperature of the heating component is different in different stages. For example, in the B heat preservation stage, the temperature of the heating component is maintained in the heat preservation temperature range, and in the C suction heating stage, the temperature of the heating component 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, the length R2_2, and the length R2_3 are all greater than the length R1.

[0073] Among them, the atomizer also includes two actions: power on and power off. Usually, the heating stage of the heating component is between the two actions of power on and power off. Exemplarily, a complete puffing process of a user can be power on, A preheating, B insulation, C puffing and heating, D cooling, and power off. When the user needs to puff multiple times, the order of each stage can be power on → A → B → C → D → B → C → D → B → C → D → B →…… ...

[0074] In this embodiment, powering on means that the atomizer is turned on after detecting a trigger signal (including but not limited to pressing a button, sliding the cover, etc.) in the off state. After powering on, the atomizer has 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 necessary stage, but the movement of the atomized matrix "R1" in this stage is necessary; if there is an obvious temperature rise process before "B insulation", it is considered that the "A preheating" stage exists.

[0076] Among them, "B insulation" means that after the machine is turned on, the heating component is maintained in a temperature range that is significantly higher than the ambient temperature, but the temperature is not high enough to cause the smoke release layer to produce obvious aerosol. "B insulation" is used as a preheating for "C puff heating" to reduce the temperature rise time of "C puff heating".

[0077] Among them, "D cooling" refers to the control of cooling or natural cooling after the end of puffing (including but not limited to the recovery of air pressure signal and the arrival of the upper limit of puffing time), or in the latter part of puffing. If the cooling process has been done in the "C puffing and heating" stage, "D cooling" may not be a necessary stage in a complete puffing process of the user.

[0078] Among them, after "shutdown", the atomizer enters a state where it cannot be heated, 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 heating by suction, D cooling”, a forced shutdown signal is generated (including but not limited to key presses, sliding the cover, etc.).

[0080] (2) During the "B insulation" stage, the "C suction heating" stage is not triggered and the duration reaches the set upper limit (e.g. 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 each time it is puffed is: the total distance moved by 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, so that the heating area of ​​the atomized matrix per puff can be greater than the area of ​​the heating component, so as to increase the aerosol release per puff.

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

[0083] 1. After the user turns on the machine, the heating component starts to heat up and the atomized matrix starts 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 starts to inhale, in the first half of an inhalation, 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 the inhalation, 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 that the user takes 3 seconds to puff once, the device moves 5mm during the first 1.5 seconds of heating and 5mm during the last 1.5 seconds of heating, i.e., puffing once and moving twice. The temperature of the heating component during the first 1.5 seconds of movement is higher than that 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 atomization matrix, and the temperature of the heating component during the last 1.5 seconds of movement should be lower than the atomization temperature of the atomization matrix, i.e., the insulation temperature. In the last 1.5 seconds of movement, the residual temperature of the first 1.5 seconds is used to preheat the atomization matrix for the next puff, so that the next puff can start smoking faster.

[0085] The embodiment of the present application can improve 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 smoke initiation. 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 aerosol release amount, 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 machine start-up state, so that after the cold machine is turned on, it can enter a state where it can quickly heat up and smoke. And 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, causing aerosol loss.
