Description

Technical Field

[0001] The present application relates to the field of atomization equipment, and in particular to an aerosol generating device. Background Art

[0002] The aerosol generating device (i.e., electronic atomization device) includes an atomizer and a power supply device. The air inlet of the device is usually arranged at the bottom or the gap between the power supply device and the atomizer housing is used as the air inlet. The air outlet of the device is arranged at the suction nozzle of the atomizer. The air inlet and air outlet of the device are directly connected to the outside world. Since the air inlet and air outlet of the device are connected to the outside world, there is a pressure difference between the internal air pressure of the device and the external atmospheric pressure. During the transportation of the device, especially in the case of air transportation, there is a large pressure difference between the internal air pressure of the device and the external atmospheric pressure. At this time, since the device is affected by the internal and external pressure difference, the aerosol-forming substrate stored in the atomizer is easy to leak out from the liquid outlet of the atomizer, causing the aerosol-forming substrate to flow to the air inlet, air outlet, etc., resulting in leakage of the aerosol-forming substrate.

[0047] The present application is further described in detail below through specific implementation methods in conjunction with the accompanying drawings.

[0048] The present application provides an aerosol generating device. In a first embodiment of the present application, Figure 1a to Figure 1d As shown, the aerosol generating device includes a main body 100 and a shell 200, wherein the shell 200 has a accommodating space (not shown in the figure), and the main body 100 is installed in the accommodating space. When the main body 100 or the shell 200 is subjected to external force, the main body 100 and the shell 200 can move relative to each other.

[0049] The main body 100 is used to atomize the aerosol-forming substrate to generate an aerosol. The main body 100 has an airflow channel (not shown) inside, and the airflow channel is used to circulate air and / or aerosol. In actual applications, the main body 100 stores an aerosol-forming substrate inside. When the main body 100 enters a normal working state, the main body 100 atomizes the aerosol-forming substrate to generate an aerosol, and the generated aerosol is released to the outside through the airflow channel, or external air enters the airflow channel to bring the generated aerosol out to the outside, so that the user can use the aerosol.

[0050] The main body 100 includes a proximal end 101, a distal end (not shown) and a surface (not shown), the distal end is arranged opposite to the proximal end 101, the surface is located between the proximal end 101 and the distal end, and when the aerosol generating device is in a closed state, the surface of the main body 100 is covered by the shell 200 and is not visible. It should be understood by those skilled in the art that the proximal end 101 and the distal end of the main body 100 in the present application are only used to represent the two ends of the main body 100, which are only relative, and do not limit the specific meanings of "proximal end" and "distal end".

[0051] The housing 200 includes a first housing 201 and a second housing 202 . The first housing 201 and / or the second housing 202 can move relative to the main body 100 under the action of external force.

[0052] When the first shell 201 and / or the second shell 202 moves relative to the main body 100, a first relative displacement is generated between the first shell 201 and the second shell 202 to form a first area 301, so that the airflow channel is connected to the outside. The first shell 201 and / or the second shell 202 moves relative to the main body 100 under the action of an external force, so that the airflow channel is opened, forming convection with the outside and connecting to the outside.

[0053] Specifically, the first shell 201 and / or the second shell 202 moves relative to the main body 100 under the action of external force, which may include the following situations:

[0054] In the case where the first shell 201 is moved relative to the main body 100 by an external force alone, the first shell 201 is movably connected to the main body 100, and the second shell 202 may be fixedly connected to the main body 100 and cannot move relative to the main body 100, or the second shell 202 may be movably connected to the main body 100 and can move relative to the main body 100. Similarly, in the case where the second shell 202 is moved relative to the main body 100 by an external force alone, the second shell 202 is movably connected to the main body 100, and the first shell 201 may be fixedly connected to the main body 100 and cannot move relative to the main body 100; or the first shell 201 may be movably connected to the main body 100 and can move relative to the main body 100. In the case where both the first shell 201 and the second shell 202 are moved relative to the main body 100 by an external force, the first shell 201 and the second shell 202 are both movably connected to the main body 100.

[0055] When the first shell 201 is moved relative to the main body 100 by an external force, the first shell 201 is displaced in the longitudinal direction of the main body 100 toward the proximal end 101 of the main body 100, and at this time, the first shell 201 and the second shell 202 are relatively displaced; when the second shell 202 is moved relative to the main body 100 by an external force, the second shell 202 is displaced toward the distal end of the main body 100, and at this time, the first shell 201 and the second shell 202 are also relatively displaced. In the case where the first shell 201 and the second shell 202 are both moved relative to the main body 100 by an external force, they can be moved relative to the main body 100 at the same time, or they can be moved relative to the main body 100 in sequence, and at this time, the first shell 201 and the second shell 202 are also relatively displaced.

[0056] It can be seen from this that when only the first shell 201 or the second shell 202 moves relative to the main body 100 due to external force, or when both the first shell 201 and the second shell 202 move relative to the main body 100 due to external force, a first relative displacement is generated between the first shell 201 and the second shell 202 to form the first area 301.

[0057] In this embodiment, preferably, the first shell 201 is movably connected to the main body 100, and the second shell 202 is fixedly connected to the main body 100. When the first shell 201 is subjected to external force, the first shell 201 is displaced in the longitudinal direction of the main body 100 toward the proximal end 101 of the main body 100. At this time, the first shell 201 and the second shell 202 generate a first relative displacement to form a first area 301, so that the airflow channel is connected to the outside.

[0058] Here, for the case where the second shell 202 is fixedly connected to the main body 100, only the case where the first shell 201 can move relative to the main body 100 under the action of external force is taken as an example. Of course, not only can the first shell 201 move relative to the main body 100 under the action of external force, but the main body 100 can also move relative to the first shell 201 under the action of external force, so that the first shell 201 and the second shell 202 produce a first relative displacement to form a first area 301.

[0059] Specifically, the first area 301 forms an air inlet, which is connected to the entrance of the air flow channel. At this time, external air can enter the air flow channel from the air inlet formed by the first area 301; or, the first area 301 forms an air outlet, which is connected to the outlet of the air flow channel. At this time, the air flowing into the air flow channel from the outside and / or the aerosol generated by the aerosol generating device are released from the air flow channel from the air outlet formed by the first area 301.

[0060] In a specific embodiment, the first housing 201 includes a top end 210 and a first joint end 211, and the top end 210 of the first housing 201 is arranged opposite to the first joint end 211; the second housing 202 includes a bottom end 220 and a second joint end 221, and the bottom end 220 of the second housing 202 is arranged opposite to the second joint end 221, and the second joint end 221 is connected to the first joint end 211. The top end 210 of the first housing 201 and the bottom end 220 of the second housing 202 are arranged opposite to each other, and are the top end and the bottom end of the housing 200, respectively. Similarly, it should be understood by those skilled in the art that the top end and the bottom end of the present application are only used to indicate the two ends of the housing 200, and are only relative, and do not limit the specific meaning of "top end" and "bottom end". Specifically, a first relative displacement is generated between the first joint end 211 of the first housing 201 and the second joint end 221 of the second housing 202 to form the first region 301.

[0061] In a specific embodiment, the top end 210 of the first shell 201 has a first opening 212 . The first opening 212 does not cover the proximal end 101 of the main body 100 , and an edge of the first opening 212 is engaged with the proximal end 101 of the main body 100 .

[0062] When the first shell 201 moves relative to the main body 100, in addition to the above-mentioned first area 301 formed between the first shell 201 and the second shell 202, that is, the above-mentioned first area 301 is formed between the first joining end 211 of the first shell 201 and the second joining end 221 of the second shell 202, a second relative displacement is also generated between the first opening 212 of the first shell 201 and the proximal end 101 of the main body 100 to form a second area 302.

[0063] Of course, when the second shell 202 moves relative to the main body 100, a third relative displacement is also generated between the bottom end 220 of the second shell 202 and the distal end of the main body 100 to form a third area (not shown in the figure), which is not specifically limited in this application.

[0064] Specifically, when the first area 301 forms an air inlet, the second area 302 forms an air outlet, which is connected to the outlet of the air flow channel. At this time, the air flowing into the air flow channel from the outside, and / or the aerosol generated by the aerosol generating device is released from the air flow channel from the air outlet formed by the first area 301; or, when the first area 301 forms an air outlet, the second area 302 forms an air inlet, which is connected to the inlet of the air flow channel, and at this time, the external air can enter the air flow channel from the air inlet formed by the first area 301.

[0065] Specifically, the first region 301 is an opening region formed by the separation of the first joint end 211 of the first shell 201 and the second joint end 221 of the second shell 202, and the opening region includes the gap between the first joint end 211 of the first shell 201, the second joint end 221 of the second shell 202 and the surface of the main body 100, thereby forming an air inlet or an air outlet. The second region 302 is a hollow region formed by the difference between the first opening 212 of the first shell 201 and the proximal end 101 of the main body 100, thereby forming an air outlet or an air inlet.

[0066] In this embodiment, preferably, the first area 301 forms an air inlet, and the second area 302 forms an air outlet, and the air inlet and the air outlet are respectively connected to the inlet and the outlet of the air flow channel, so that the air flow channel is connected to the external atmosphere.

[0067] Since the first shell 201 and / or the second shell 202 are not subjected to external force to produce relative displacement with respect to the main body to form an air inlet and an air outlet, the air flow channel is not connected to the outside world, so that when the aerosol generating device is in a closed state (not in use), that is, in a static state or in the process of transportation or carrying, it will not form convection with the outside world, and will not be affected by the internal and external air pressure difference, effectively avoiding the leakage of the aerosol forming substrate of the aerosol generating device due to the influence of the internal and external air pressure difference.

[0068] In this embodiment, the surface of the main body 100 includes a first portion 301 .

[0069] In a specific embodiment, the first joint end 211 of the first shell 201 and the second joint end 221 of the second shell 202 are two edges of matching shapes and sizes, and the first joint end 211 of the first shell 201 abuts against the second joint end 221 of the second shell 202. The first joint end 211 of the first shell 201 and the second joint end 221 of the second shell 202 may have end surface edges that are flush with each other and directly abut, or one end surface edge of the first joint end 211 of the first shell 201 and the second joint end 221 of the second shell 202 may be a concave edge, and the other end surface is flush with each other and inserted into the concave edge for abutment.

[0070] When the first shell 201 and / or the second shell 202 moves relative to the main body 100 under the action of external force to form the above-mentioned first area 301, the above-mentioned first area 301 does not cover the first part 103 on the surface of the main body 100. The first area 301 is an opening area surrounded by the first part 103 on the surface of the main body 100 and the end faces of the first joint end 211 and the second joint end 221.

[0071] In another specific embodiment, the first joining end 211 and the second joining end 221 are two matching joining ends, and the first joining end 211 and the second joining end 221 are mutually socketed. When the first area 301 is formed between the first shell 201 and the second shell 202, the first area 301 includes at least a portion of the first joining end 211, or the first area 301 includes at least a portion of the second joining end 221, that is, when the first area 301 is formed between the first shell 201 and the second shell 202, the above-mentioned first area 301 formed can be the first part 103 covering the surface of the main body 100, or can be the first part 103 not covering the surface of the main body 100.

[0072] Specifically, when the first joint end 211 is sleeved on the second joint end 221, the first area 301 can be the area enclosed between the outer surface of the second joint end 221 and the end surface of the first joint end 211 when the first shell 201 and / or the second shell 202 are moved relative to the main body 100 by external force, and the first area 301 covers the first part 103 of the surface of the main body 100; or, when the second joint end 221 is sleeved on the first joint end 211, the first area 301 can be the area enclosed between the outer surface of the first joint end 211 and the end surface of the second joint end 221 when the first shell 201 and / or the second shell 202 are moved relative to the main body 100 by external force, and the first area 301 also covers the first part 103 of the surface of the main body 100. When the first shell 201 and / or the second shell 202 moves relative to the main body 100 under the action of external force until the first joint end 211 is separated from the second joint end 221 and the first part 103 of the surface of the main body 100 is exposed, the first area 301 does not cover the first part 103 of the surface of the main body 100.

[0073] The outer surface of the first joining end 211 may be a partial area of ​​the first joining end 211 or the entire area of ​​the first joining end 211 ; similarly, the outer surface of the second joining end 221 may be a partial area of ​​the second joining end 221 or the entire area of ​​the second joining end 221 .

[0074] In a specific embodiment, the first joint end 211 of the first shell 201 and the second joint end 221 of the second shell 202 may also be uneven end surfaces of various shapes. When the first shell 201 and / or the second shell 202 are moved relative to the main body 100 by an external force so that the first part 103 of the surface of the main body 100 is exposed, the first joint end 211 of the first shell 201 and the second joint end 221 of the second shell 202 may surround areas of different shapes. For example, when the shell 200 is a circular tube shell and the end surfaces of the first joint end 211 and the second joint end 221 are mutually offset inclined surfaces, the first joint end 211 and the second joint end 221 surround an elliptical area, that is, the exposed first part 103 of the surface of the main body 100 is an elliptical surface, such as Figure 1c and Figure 1d shown.

[0075] In another specific embodiment, the first joining end 211 of the first shell 201 and the second joining end 221 of the second shell 202 can be transverse annular end faces. When the first shell 201 and / or the second shell 202 are moved relative to the main body 100 by an external force so that the first part 103 of the surface of the main body 100 is exposed, the first joining end 211 of the first shell 201 and the second joining end 221 of the second shell 202 form an annular area, that is, the exposed first part 103 of the surface of the main body 100 is an annular surface.

[0076] In a specific embodiment, the aerosol generating device is provided with an information display area, which is used to display one or more of identification information, aerosol forming substrate remaining information, environmental information, working status information, power information, self-parameter information and the like, wherein the aerosol forming substrate remaining information can be displayed transparently or as data; the environmental information includes external environmental information and / or internal environmental information, the external environmental information includes external environmental temperature, humidity, etc., the internal environmental information includes internal temperature of the device, component temperature, etc., and the self-parameter information includes the pressure difference between the inside and outside of the device, component resistance, etc.

[0077] Information is displayed in the information display area so that the user can learn about the current status information when using the aerosol generating device, which helps the user to predict the usage status. For example, when the remaining amount of aerosol forming substrate is too little, the user can predict that an aerosol forming substrate can be added, or the container storing the aerosol forming substrate can be replaced, or the device can be stopped. When the air pressure difference between the inside and outside of the device is too large, it may lead to a poor experience, so the user can choose to stop using it.

[0078] Specifically, the information display area can be set in the first part 103 of the surface of the main body 100. When the first shell 201 and / or the second shell 202 moves relative to the main body 100 under the action of external force so that the first part 103 of the surface of the main body 100 is exposed, information can be displayed through the information display area of ​​the first part 103 of the surface of the main body 100.

[0079] Of course, the information display area may also be set on the housing 200 , and the information display area may be a partial area of ​​the housing 200 or the entire area of ​​the housing 200 .

[0080] In a specific embodiment, when the first area 301 is formed between the first shell 201 and the second shell 202 , the aerosol generating device is activated.

[0081] Specifically, the aerosol generating device can be started only by powering on the aerosol generating device, that is, the main body 100 is powered on and enters a standby state. The aerosol generating device enters a normal working state only when it is triggered by a normal working signal in the standby state. At this time, the main body 100 works normally and atomizes the aerosol-forming substrate to generate an aerosol.

[0082] For example, when the user operates the aerosol generating device so that the first shell 201 moves relative to the main body and forms the above-mentioned first area 301 between the first shell 201 and the second shell 202, the aerosol generating device is powered on. After the aerosol generating device is powered on, when the user performs other operations on the aerosol generating device (such as suction, blowing, etc.), the aerosol generating device enters a normal working state and atomizes the aerosol-forming substrate to generate an aerosol.

[0083] Alternatively, the aerosol generating device is started by triggering the aerosol generating device to be powered on, and the aerosol generating device enters a normal working state.

[0084] For example, when the user operates the aerosol generating device so that the first shell 201 moves relative to the main body and forms the above-mentioned first area 301 between the first shell 201 and the second shell 202, the aerosol generating device is powered on. When the aerosol generating device is powered on, the user does not need to perform other operations on the aerosol generating device. The aerosol generating device atomizes the aerosol-forming substrate to generate an aerosol. In other words, the aerosol generating device can generate aerosol after being powered on.

[0085] In the present application, the relative movement of the first shell 201 and / or the second shell 202 and the main body 100 under the action of external force can trigger the self-start of the aerosol generating device, so that the aerosol generating device can be provided with a mechanical power switch or not. In the case where the aerosol generating device is not provided with a mechanical power switch, the start can be triggered by the relative movement of the shell and the main body; in the case where the aerosol generating device is provided with a mechanical power switch, the device can be triggered to start by pressing the power switch or the relative movement of the shell and the main body, thereby realizing the diversification of the device function implementation methods and improving the user experience. Moreover, in the case where the aerosol generating device is not provided with a mechanical power switch, it can also not affect the consistency of the appearance of the device, and simplify the device structure, which is conducive to reducing the size of the device and realizing the miniaturization of the device.

[0086] In this embodiment, preferably, the aerosol generating device does not have a mechanical switch on the shell, but an electronic switch element is provided inside the aerosol generating device, such as a MOS tube, a triode or a relay. Of course, a mechanical switch can also be provided inside the aerosol generating device.

[0087] In a specific embodiment, the aerosol generating device of the present application further includes a start indicator light (not shown). When the aerosol generating device is started, the start indicator light emits light, and the light emitted by the start indicator light is transmitted to the outside. The start indicator light can be set on the main body 100 or the shell 200 according to actual conditions.

[0088] Specifically, the start indicator light can be set inside the main body 100. When the first shell 201 moves along the main body 100 to form the above-mentioned second area 302, the light emitted by the start indicator light passes through the airflow channel and the second area 302 in sequence, or passes through the gap between the main body 100 and the shell 200 and the second area 302 in sequence and is scattered to the outside from the first opening 212 of the first shell 201, or is directly scattered to the outside through the gap between the main body 100 and the shell 200; or a light-transmitting area is set in the corresponding area of ​​the shell 200, and the start indicator light scatters the light source through the light-transmitting area.

[0089] Alternatively, the start indicator light can also be set at the proximal end 101 of the main body 100, the surface of the main body 100 or the inner surface of the shell 200. When the first shell 201 moves along the main body 100 to form the above-mentioned second area 302, the light emitted by the start indicator light passes through the second area 302, or passes through the gap between the main body 100 and the shell 200 and the second area 302 in turn and is scattered outward from the first opening 212 of the first shell 201, or is directly scattered to the outside through the gap between the main body 100 and the shell 200; or a light-transmitting area is set in the corresponding area of ​​the shell 200, and the start indicator light scatters the light source through the light-transmitting area.

[0090] Alternatively, the start indicator light may also be provided on the housing 200, and the light of the start indicator light is directly emitted to the outside; the start indicator light may also be a partial area or the entire area of ​​the housing 200, and the housing 200 directly emits light for indication.

[0091] By emitting a light indication on the start indicator light when the aerosol generating device is started, the user is prompted that the device has been started. At the same time, by emitting light from the inside to the outside, or by the shell 200 itself emitting light, the device can display dynamic colors and have a cool feeling, thereby enhancing the customer experience.

[0092] In a specific embodiment, if Figure 3 As shown, the aerosol generating device of the present application further includes a position detection module 401 .

[0093] When the main body 100 or the housing 200 moves, the position detection module 401 detects the position information of the main body 100 or the housing 200, and obtains the current position information of the main body 100 or the housing 200. The position detection module 401 can detect the position information of the main body 100 or the housing 200 in real time, or can detect the position information when the main body 100 or the housing 200 starts to move and stops moving. The position detection module 401 stores the current position information obtained.

[0094] After acquiring the current position information of the main body 100 or the shell 200, the position detection module 401 compares the current position information of the main body 100 or the shell 200 with the preset start-up position information. If the current position information of the main body 100 or the shell 200 does not match the preset start-up position information, it is determined that the movement of the main body 100 or the shell 200 has not passed through the preset start-up position, and an abnormal signal is fed back to prevent the aerosol generating device from starting.

[0095] Specifically, when the main body 100 and the shell 200 move relative to each other, for example, the first shell 200 moves relative to the main body 100 so that a first area 301 is formed between the first shell 201 and the second shell 202, if the current position information of the first shell 201 moving along the main body 100 does not match the preset start-up position information, that is, the movement of the first shell 201 has not passed through the preset start-up position, at this time, the first area 301 formed by the relative movement of the first shell 201 and the main body 100 is not the area formed after the first shell 201 moves through the preset start-up position, then the aerosol generating device does not start.

[0096] Thus, when the first shell 201 moves relative to the main body 100 without user behavior, but when the first shell 201 stops moving, the first shell 201 has not passed the preset starting position, the aerosol generating device determines that it is an erroneous operation that causes the first shell 201 to move relative to the main body 100 without starting. Therefore, it is possible to avoid the aerosol generating device from self-starting due to erroneous operation without user behavior, and avoid the problem of self-starting of the equipment due to erroneous operation, resulting in waste of resources, potential safety hazards, and other problems.

[0097] On the other hand, in this embodiment, when the position detection module 401 detects that the position information of the main body 100 or the shell 200 during the movement matches the preset initial position information and the preset start position information, it determines that the main body 100 or the shell 200 moves through the preset initial position and the preset start position in sequence, and feeds back a start signal to start the aerosol generating device. That is, during the movement of the main body 100 or the shell 200, after the position detection module 401 detects that the position information of the main body 100 or the shell 200 matches the preset initial position information, when the main body 100 or the shell 200 continues to move and a certain position information matches the preset initial position information, it determines that the main body 100 or the shell 200 moves through the preset initial position and the preset start position in sequence, and then determines that the main body 100 or the shell 200 moves under the action of normal user behavior, thereby feeding back a start signal to start the aerosol generating device.

[0098] Specifically, taking the case where the first shell 201 moves relative to the main body 100 under the action of an external force as an example, the position detection module 401 obtains the position information of the first shell 201 during the movement of the first shell 201, and compares the current position information of the first shell 201 with the preset initial position information and the preset start position information respectively. If the current position information of the first shell 201 matches the preset initial position information, it is determined that the first shell 201 has passed through the preset initial position at this time; if the current position information of the first shell 201 matches the preset start position information, it is determined that the first shell 201 has passed through the preset start position at this time. Therefore, if during the movement of the first shell 201, the position detection module 401 first detects that the position information of the first shell 201 matches the preset initial position information, and then detects that the position information of the first shell 201 matches the preset start position information, it is determined that the first shell 201 has successively passed through the preset initial position and the preset start position during the movement, and at this time, the position detection module 401 feeds back a start signal, thereby triggering the aerosol generating device to start.

[0099] The above description is based only on the case where the first shell 201 moves relative to the main body 100. Similarly, when the second shell 202 moves relative to the main body 100, if the second shell 202 stops moving without passing through the preset start position, the aerosol generating device cannot be triggered to start automatically. The aerosol generating device starts automatically only when the second shell 202 stops moving and passes through the preset start position. Here, the preset start position referenced by the movement of the second shell 202 and the preset start position referenced by the movement of the first shell 201 are two different preset start positions.

[0100] Therefore, in the case where both the first shell 201 and the second shell 202 move relative to the main body 100, when the first shell 201 and the second shell 202 stop moving and one of them has not passed through the corresponding preset starting position, the aerosol generating device cannot be triggered to self-start. The aerosol generating device can only be triggered to self-start when both the first shell 201 and the second shell 202 stop moving and both pass through the corresponding preset starting positions.

[0101] Specifically, Figure 3 As shown, the position detection module 401 includes a sensor component 411 and a first microcontroller 412 electrically connected to the sensor component 411 .

[0102] The sensor assembly 411 is used to detect the position information of the main body 100 or the shell 200 when the main body 100 or the shell 200 moves, and obtain the current position information of the main body 100 or the shell 200. The first microcontroller 412 is used to feedback a start signal or an abnormal signal according to the position information of the main body 100 or the shell 200, so as to start or not start the aerosol generating device.

[0103] The sensor assembly 411 may be one or more sensors for detecting whether the first shell 201 and / or the second shell 202 have passed through a preset position during the relative movement with the main body 100. The present application does not limit the type of sensor having this function. For example, the sensor assembly 411 may be a sensor for detecting the movement trajectory of the first shell 201 and / or the second shell 202 on the main body 100, such as an acceleration sensor, and the sensor assembly 411 includes at least one sensor. The first microcontroller 412 is disposed inside the main body 100, and the sensor assembly 411 may be disposed inside the main body 100, or on the surface of the main body 100, or inside the shell 200. When the sensor assembly 411 includes multiple sensors, they may also be disposed in these three positions.

[0104] Specifically, taking the example of the first shell 201 moving relative to the main body 100 under the action of external force, when the first shell 201 moves along the first direction of the main body 100, for example, in the counterclockwise direction along the circumference of the main body 100, when the sensor component 411 does not detect that the current position information of the first shell 201 matches the preset start position information, that is, the first shell 201 is not detected to have moved through the preset start position, the first microcontroller 412 determines that the first shell 201 has not moved through the preset start position, and thus feeds back an abnormal signal so that the aerosol generating device does not start.

[0105] The movement of the first shell 201 without passing through the preset starting position may be a situation where it passes through the preset initial position during the movement but does not pass through the preset starting position, or it may be a situation where it starts to move from any position between the preset initial position and the preset starting position but does not pass through the preset starting position.

[0106] When the sensor component 411 detects that the current position information of the first shell 201 matches the preset starting position information, and a previous position information of the first shell 201 also matches the preset initial position information, the first microcontroller 412 determines that the movement of the first shell 201 sequentially passes through the preset initial position and the preset starting position, thereby feeding back a starting signal to trigger the start of the aerosol generating device.

[0107] After the aerosol generating device is started, when the sensor component 411 detects that the first shell 201 moves in a second direction along the main body 100, which is opposite to the first direction, for example, the first shell 201 passes through a preset starting position in a clockwise direction along the circumference of the main body 100, that is, leaves the preset starting position, or passes through the preset starting position and the preset initial position in sequence, that is, reaches the preset initial position from the preset starting position, the first microcontroller 412 feeds back a shutdown signal or a standby signal to trigger the aerosol generating device to switch from the startup state to the shutdown state or enter the standby state.

[0108] Alternatively, the sensor component 411 can be a sensor that detects when the first shell 201 passes through a certain position point on the main body 100, such as a photoelectric sensor. The sensor component 411 includes at least a first sensor and a second sensor that are spaced apart on the main body 100 and / or the shell 200. The first sensor and the second sensor respectively detect whether the movement of the first shell 201 passes through a preset initial position and a preset start position.

[0109] Specifically, taking the first sensor and the second sensor as photoelectric sensors as an example, when the first sensor detects that the position information of the first shell 201 moving relative to the main body 100 matches the preset initial position information, and the second sensor does not detect that the position information of the first shell 201 moving relative to the main body 100 matches the preset start position information, it means that the sensor component 411 detects that the first shell 201 moves on the main body 100 without passing through the preset start position. At this time, the first microcontroller 412 feeds back an abnormal signal to trigger the aerosol generating device not to start.

[0110] When the first sensor detects that the position information of the first shell 201 moving relative to the main body 100 matches the preset initial position information, and when the second sensor detects that the position information of the first shell 201 moving relative to the main body 100 matches the preset starting position information, it means that the sensor component 411 detects that the first shell 201 moves on the main body 100 and passes through the preset initial position and the preset starting position in sequence. At this time, the first microcontroller 412 feeds back a start signal to trigger the start of the aerosol generating device.

[0111] When the second sensor detects that the first shell 201 moves in the opposite direction relative to the main body 100 and passes through the preset initial position again, that is, leaves the preset initial position, the first microcontroller 412 feeds back a shutdown signal or a standby signal to trigger the aerosol generating device to switch from the startup state to the shutdown state or the standby state. Alternatively, after the second sensor detects that the first shell 201 moves in the opposite direction relative to the main body 100 and passes through the preset startup position again, the first sensor also detects that the first shell 201 moves in the opposite direction relative to the main body 100 and passes through the preset initial position again, that is, when the first shell 201 moves from the preset startup position to the preset initial position, the first microcontroller 412 feeds back a shutdown signal or a standby signal to trigger the aerosol generating device to switch from the startup state to the shutdown state or the standby state.

[0112] Further, in a specific embodiment, if Figure 3 As shown, the aerosol generating device further includes a time detection module 402 .

[0113] The time detection module 402 is used to detect the movement time required for the main body 100 or the shell 200 to successively go through a preset initial position and a preset starting position; and when it is detected that the movement time exceeds a preset starting time (such as 1s), an abnormal signal is fed back to prevent the aerosol generating device from starting; when it is detected that the movement time is less than the preset starting time, a start signal is fed back to start the aerosol generating device.

[0114] Specifically, taking the case where the first shell 201 moves relative to the main body 100 under the action of external force as an example, when the position detection module 401 detects that the first shell 201 moves through a preset initial position, the time detection module 402 starts timing, or records the current time point, and when the position detection module 401 detects that the first shell 201 moves through a preset starting position, the time detection module 402 stops timing and obtains the recorded duration, or the time detection module 402 records the current time point and obtains the time interval between the two time points. At this time, if the time detection module 402 detects that the recorded duration or time interval exceeds the preset starting time, it is determined to be an abnormal phenomenon, and an abnormal signal is fed back to prevent the aerosol generating device from starting; the aerosol generating device will only start automatically when the time detection module 402 detects that the recorded duration or time interval is less than the preset starting time.

[0115] Those skilled in the art should understand that, in actual applications, when normal user behavior causes the first shell 201 to move relative to the main body 100, the continuity of the user's action causes the first shell 201 to move from a preset initial position to a preset start position. At this time, the movement time of the first shell 201 must be less than the preset start time, and the relative movement of the first shell 201 and the main body 100 triggers the aerosol generating device to self-start. In the case of non-user behavior, that is, in the case of misoperation, when the first shell 201 is moved relative to the main body 100 by an external force not caused by the user behavior, after the first shell 201 starts to move from the starting position, the first shell 201 will stop moving without passing through the preset starting position due to insufficient force. After stopping for a period of time, it will move again due to the external force not caused by the user behavior before passing through the preset starting position. At this time, the position detection module 401 detects that the first shell 201 has moved through the preset starting position and determines it as a condition that can trigger the start of the aerosol generating device. However, since the first shell 201 has moved for many times due to the misoperation not caused by the user behavior, during this process, the movement time required for the first shell 201 to reach the preset starting position from the preset initial position, that is, in the process of the first shell 201 reaching the preset starting position from the preset initial position, the total time of each movement of the first shell 201 and the time of stopping the movement in the middle must exceed the preset start time. Therefore, the time detection module 402 feeds back an abnormal signal, so that the aerosol generating device does not start.

[0116] It can be seen from this that in the case of an erroneous operation, although the first shell 201 moves relative to the main body 100 and sequentially passes through the preset initial position and the preset starting position, when the time required for the first shell 201 to reach the preset starting position from the preset initial position exceeds the preset starting time, the aerosol generating device does not start, thereby being able to further detect the erroneous operation. Through the dual erroneous operation detection of the position detection module 401 and the time detection module 402, the aerosol generating device can be effectively prevented from self-starting due to erroneous operation, resulting in waste of resources and safety hazards.

[0117] Further, after the aerosol generating device is started, the time detection module 402 detects the working time of the aerosol generating device. When it is detected that the current working time of the aerosol generating device exceeds the preset working time (such as 10s), the time detection module 402 feeds back a shutdown signal or a standby signal to shut down the aerosol generating device or enter a standby state.

[0118] Therefore, when the user uses the device for too long, the device itself can provide protection, which can also prevent the user from overusing the functions provided by the device to the detriment of health. It can also prevent the aerosol generating device from starting up for too long due to misoperation, thereby causing waste of resources, safety hazards, and other problems.

[0119] In addition, when the aerosol generating device is in the standby state, the time detection module 402 detects the standby time of the aerosol generating device. When it is detected that the current standby time of the aerosol generating device exceeds the preset standby time (such as 2 minutes), the time detection module 402 feeds back a shutdown signal to shut down the aerosol generating device.

[0120] Therefore, when the device is in standby mode for a long time and no user activates the device, the device will automatically enter the shutdown state. It can also automatically shut down when the user forgets to shut down or causes the device to be in standby mode for a long time due to erroneous operation, thus saving resources and avoiding safety hazards.

[0121] Specifically, Figure 3As shown, the time detection module 402 includes a timer 413 and a second microcontroller 414 electrically connected to the timer 413. The timer 413 is used to record the movement time required for the main body 100 or the shell 200 to successively go through the preset initial position and the preset starting position, and the second microcontroller 414 feeds back a start signal or an abnormal signal according to the movement time, so that the aerosol generating device is started or not started. Moreover, after the aerosol generating device is started, the working time of the aerosol generating device recorded by the timer 413, and the second microcontroller 414 controls the aerosol generating device to maintain a normal working state according to the working time, or controls the aerosol generating device to shut down or enter a standby state. After the aerosol generating device is in the standby state, the standby time of the aerosol generating device recorded by the timer 413, and the second microcontroller 414 controls the aerosol generating device to maintain a standby state or switch to a shutdown state according to the standby time.

[0122] In this embodiment, the movement of the first shell 201 relative to the main body 100 under the action of external force is taken as an example. When the timer 413 records that the movement time required for the first shell 201 to successively go through the preset initial position and the preset starting position exceeds the preset starting time, the second microcontroller 414 feeds back an abnormal signal to prevent the aerosol generating device from starting; when the movement time recorded by the timer 413 is less than the preset starting time, the second microcontroller 414 feeds back a start signal to start the aerosol generating device.

[0123] After the aerosol generating device is started, the timer 413 records the working time of the aerosol generating device. When the second microcontroller 414 detects that the working time recorded by the timer 413 exceeds the preset working time, it feeds back a shutdown signal or a standby signal, so that the aerosol generating device switches from a normal working state to a shutdown or standby state; and when the working time recorded by the timer 413 is less than the preset working time, the second microcontroller 414 still feeds back a start signal, so that the aerosol generating device maintains a normal working state.

[0124] When the aerosol generating device is in the standby state, the timer 413 records the standby time of the aerosol generating device. When the second microcontroller 414 detects that the standby time recorded by the timer 413 exceeds the preset standby time, it feeds back a shutdown signal to switch the aerosol generating device from the standby state to the shutdown state. When the current standby time of the aerosol generating device is less than the preset standby time, the aerosol generating device is still in the standby state. When the aerosol generating device is in the standby state, if the aerosol generating device receives a start trigger, it starts from the standby state.

[0125] Those skilled in the art should understand that the above-mentioned preset initial position and preset start position are two different positions in succession when the aerosol generating device starts to move from a closed state, and when the aerosol generating device starts to move from an open state, the preset start position and the preset initial position are two different positions in succession. The above-mentioned preset initial position and the preset start position can be the starting position and the end position of the movement of the main body 100 or the shell 200, or can be two different positions in succession between the starting position and the end position of the movement of the main body 100 or the shell 200. The above-mentioned preset initial position can be started from the preset initial position, or can be passed through the preset initial position during the movement, or can be reached when the movement stops; similarly, the above-mentioned preset start position can be started from the preset start position, or can be passed through the preset start position during the movement, or can be reached when the movement stops.

[0126] In a specific embodiment, the main body has a charging interface 105 , and the first shell or the second shell has a second opening, the second opening does not cover the charging interface 105 , and an edge of the second opening is engaged with the charging interface.

[0127] like Figure 1b As shown, the bottom end 220 of the second shell 202 has a second opening 222 , the distal end of the main body 100 has a charging interface 105 , the second opening 222 does not cover the charging interface 105 , and the edge of the second opening 222 engages with the charging interface 105 .

[0128] Alternatively, in another specific embodiment, the first shell 201 or the second shell 202 has a charging interface 105 . Preferably, the charging interface 105 can be disposed at the bottom end 220 of the second shell 202 .

[0129] The charging interface 105 is used to connect an external power source to charge the aerosol generating device. The charging interface 105 is a wireless charging interface or a wired charging interface. The wireless charging interface may be, for example, a contact magnetic charging interface or a wireless induction charging interface. The wired charging interface may be, for example, a micro USB charging interface or a Type-C charging interface.

[0130] In a specific embodiment, in order to facilitate the use and placement of the aerosol generating device, the aerosol generating device is provided with at least one of a frosted layer, an anti-slip portion, a polygonal corner, a flat top, and a flat bottom. For example, the outer surface of the shell 200 is provided with a frosted layer, the outer surface of the shell 200 is provided with anti-slip portions such as convex strips and convex points, and the shell 200 is provided in a polygonal corner shape, so that the aerosol generating device has an anti-slip effect during use, and has an anti-rolling effect when parked, and also makes the device beautiful in appearance and tactile. Furthermore, if the aerosol generating device is provided with a flat top and / or bottom, the aerosol generating device can not only be parked horizontally, but also can be parked vertically without falling.

[0131] In a specific embodiment, the shell 200 is provided with a soft cover to protect the device. For example, it can reduce the impact force when the device falls. In addition, it can also increase the touch and improve the user experience.

[0132] In a specific embodiment, a temperature-sensing layer is provided on the outside of the shell 200, or the shell 200 is a temperature-sensing shell. When the device is in normal working state, when the internal structure of the device changes, the shell 200 displays different colors as the temperature changes, or each section is displayed in different colors or gradient colors.

[0133] In a specific embodiment, a light-sensitive layer is disposed on the outside of the housing 200, or the housing 200 is a light-sensitive shell, and the housing 200 emits light by itself in a relatively low light environment.

[0134] According to the actual shape of the aerosol generating device, the external force acting on the first shell 201 and the second shell 202 may be in the form of rotation, pulling, pushing or pressing, for example, Figure 1a to Figure 1d As shown, the aerosol generating device is cylindrical or quasi-cylindrical, so that the first shell 201 and the second shell 202 can be rotated, pulled, pushed or pressed by an external force to move relative to the main body 100; for example, Figure 2a to Figure 2b As shown, the aerosol generating device is arranged in a prism or quasi-prism shape, so that the first shell 201 and the second shell 202 can move relative to the main body 100 by being pulled, pushed or pressed by an external force.

[0135] Specifically, in the case where the first shell 201 moves independently relative to the main body 100 under the action of an external force:

[0136] When the first shell 201 is rotated by an external force at a certain angle, such as 90° or 180°, the first shell 201 rotates along the circumference of the main body 100. At this time, in the longitudinal direction of the main body 100, a first relative displacement is generated between the first joint end 211 of the first shell 201 and the second joint end 221 of the second shell 202 to form a first area 301, and a second relative displacement is generated between the first opening 212 of the first shell 201 and the proximal end 101 of the main body 100 to form a second area 302.

[0137] Alternatively, when the first shell 201 is pulled or pushed a certain distance, such as 1 cm or 2 cm, toward the proximal end 101 of the main body 100 by an external force, the first shell 201 moves longitudinally along the main body 100. At this time, in the longitudinal direction of the main body 100, a first relative displacement is generated between the first joint end 211 of the first shell 201 and the second joint end 221 of the second shell 202 to form a first area 301, and a second relative displacement is generated between the first opening 212 of the first shell 201 and the proximal end 101 of the main body 100 to form a second area 302.

[0138] Alternatively, when the first shell 201 is pressed by an external force, the pressing may be a touch-type pressing or a pressing time of a certain length, such as 3s or 5s. At this time, the first shell 201 moves along the longitudinal direction of the main body 100, or the first shell 201 rotates along the circumferential direction of the main body 100. In the longitudinal direction of the main body 100, a first relative displacement is generated between the first joint end 211 of the first shell 201 and the second joint end 221 of the second shell 202 to form a first area 301, and a second relative displacement is generated between the first opening 212 of the first shell 201 and the proximal end 101 of the main body 100 to form a second area 302.

[0139] For the case where the first shell 201 and the second shell 202 are both moved relative to the main body 100 by external force:

[0140] When the first shell 201 and the second shell 202 are rotated in opposite directions by a certain angle, such as 90° or 180°, due to external force, the first shell 201 and the second shell 202 both rotate along the circumference of the main body 100. At this time, in the longitudinal direction of the main body 100, a first relative displacement is generated between the first joint end 211 of the first shell 201 and the second joint end 221 of the second shell 202 to form a first area 301, and a second relative displacement is generated between the first opening 212 of the first shell 201 and the proximal end 101 of the main body 100 to form a second area 302.

[0141] Alternatively, when the first shell 201 is pulled or pushed a certain distance toward the proximal end 101 of the main body 100 by an external force, and the second shell 202 is pulled or pushed a certain distance toward the distal end of the main body 100 by an external force, for example, 1 cm or 2 cm, the first shell 201 and the second shell 202 move in opposite directions along the longitudinal direction of the main body 100. At this time, in the longitudinal direction of the main body 100, a first relative displacement is generated between the first joining end 211 of the first shell 201 and the second joining end 221 of the second shell 202 to form a first area 301, and a second relative displacement is generated between the first opening 212 of the first shell 201 and the proximal end 101 of the main body 100 to form a second area 302.

[0142] Alternatively, when the first shell 201 or the second shell 202 is pressed by an external force, or the first shell 201 and the second shell 202 are both pressed by an external force, the pressing can be a touch-type pressing, or it can be pressing for a certain length of time, such as 3s or 5s. At this time, the first shell 201 moves along the longitudinal direction of the main body 100, or the first shell 201 rotates along the circumferential direction of the main body 100. In the longitudinal direction of the main body 100, a first relative displacement is generated between the first joint end 211 of the first shell 201 and the second joint end 221 of the second shell 202 to form a first area 301, and a second relative displacement is generated between the first opening 212 of the first shell 201 and the proximal end 101 of the main body 100 to form a second area 302.

[0143] For the case where the second housing 202 moves independently relative to the main body 100 under the action of external force:

[0144] When the second shell 202 is rotated by an external force at a certain angle, such as 90° or 180°, the second shell 202 rotates along the circumference of the main body 100. At this time, in the longitudinal direction of the second shell 202, a first relative displacement is generated between the first joining end 211 of the first shell 201 and the second joining end 221 of the second shell 202 to form a first area 301.

[0145] Alternatively, when the second shell 202 is pulled or pushed a certain distance, such as 1 cm or 2 cm, toward the proximal end 101 of the main body 100 by an external force, the second shell 202 moves longitudinally along the main body 100. At this time, in the longitudinal direction of the main body 100, a first relative displacement is generated between the first joining end 211 of the first shell 201 and the second joining end 221 of the second shell 202 to form a first area 301.

[0146] Alternatively, when the second shell 202 is pressed by an external force, the pressing may be a touch-type pressing or a pressing time of a certain length, such as 3s or 5s. At this time, the second shell 202 moves along the longitudinal direction of the main body 100, or the second shell 202 rotates along the circumferential direction of the main body 100. In the longitudinal direction of the main body 100, a first relative displacement is generated between the first joint end 211 of the first shell 201 and the second joint end 221 of the second shell 202 to form a first area 301.

[0147] Of course, when the second shell 202 moves relative to the main body 100, in addition to the first relative displacement between the first joint end 211 of the first shell 201 and the second joint end 221 of the second shell 202 to form the first area 301, a third area can also be formed between the bottom end of the second shell 202 and the far end of the main body. This third area can also cooperate with the first area 301 or the second area 201 to form an air inlet or an air outlet, which is connected to the air flow channel.

[0148] Those skilled in the art should understand that, in the present application, the above-mentioned first area 301, second area 302, and first part 103 on the surface of the main body 100 are merely definitions, and for the two situations that only the first shell 201 is subjected to external force, or both the first shell 201 and the second shell 202 are subjected to external force and move relative to the main body 100, the area sizes of the first area 301 in the two situations may be equal or unequal, and the shapes may be the same or different; similarly, the area sizes of the second area 302 in the two situations may be equal or unequal, and the shapes may be the same or different; similarly, in the two situations, the area sizes of the first part 103 on the surface of the main body 100 may be equal or unequal, and the shapes may be the same or different, and there is no limitation here.

[0149] Different from the above-mentioned first embodiment, in the second embodiment of the present application, as Figure 2a and Figure 2b As shown, Figure 1a to Figure 1d The aerosol generating devices shown differ in shape. Figure 2a and Figure 2b The aerosol generating device shown is prismatic, and the end faces of the first joining end 211 of the first shell 201 and the second joining end 221 of the second shell 202 are transverse square annular end faces. When the first shell 201 is moved relative to the main body 100 by an external force, or the first shell 201 and the second shell 202 are both moved relative to the main body 100 by an external force so that the first part 103 of the surface of the main body 100 is exposed, the first joining end 211 of the first shell 201 and the second joining end 221 of the second shell 202 form an annular area, that is, the exposed first part 103 of the surface of the main body 100 is a square annular surface.

[0150] Reference Figure 1a to Figure 1d ,as well as Figure 2a to Figure 2b , Figure 1a to Figure 1d is a schematic diagram of a structure of an aerosol generating device of the present application, Figure 2a to Figure 2b The aerosol generating device structure shown is Figure 1a to Figure 1d Another structure of the aerosol generating device structure shown, in some cases, except that the shell 200 cannot rotate relative to the main body 100, the above embodiments are applicable to other situations. For example, when the shell 200 and the main body 100 are both prismatic, the shell 200 cannot rotate relative to the main body 100, while when the shell 200 is prismatic and the main body 100 is cylindrical, the shell 200 can rotate relative to the main body 100.

[0151] It should be noted that the aerosol generating device structure of the present application includes Figure 1a to Figure 1d ,as well as Figure 2a and Figure 2b Two structures, but not limited to these two structures.

[0152] The above specific examples are used to illustrate the present application, which is only used to help understand the present application and is not intended to limit the present application. For technicians in the technical field to which the present application belongs, they can also make some simple deductions, deformations or substitutions based on the ideas of the present application.
