Description

Technical Field

[0001] This application relates to the field of atomization technology, and more particularly to an aerosol generating device. Background Technology

[0002] An aerosol generating device is a product that can turn a liquid aerosol generating matrix into an aerosol through heating or other means.

[0003] In related technologies, aerosol generating devices are constructed with a storage chamber for storing the aerosol generating matrix. An atomizing component is disposed within the storage chamber, and both the external space of the aerosol generating device and the storage chamber are connected to the atomizing component. As the user inhales, the atomizing component heats the aerosol generating matrix entering the atomizing component to generate aerosol. Airflow flows from the external space of the aerosol generating device into the atomizing component, carrying the generated aerosol out of the aerosol generating device. During transportation, the aerosol generating device, once filled with the aerosol generating matrix, may experience increased internal pressure in the storage chamber due to vibration, or increased internal pressure due to the operation of the atomizing component. This pressure difference can cause the aerosol generating matrix in the storage chamber to be squeezed into the atomizing component, resulting in leakage of the aerosol generating matrix from the atomizing component.

[0024] An aerosol generating device is a product that can turn a liquid aerosol generating matrix into an aerosol through heating or other means.

[0025] In related technologies, aerosol generating devices are constructed with a storage chamber for storing the aerosol generating matrix. An atomizing component is disposed within the storage chamber, and both the external space of the aerosol generating device and the storage chamber are connected to the atomizing component. As the user inhales, the atomizing component heats the aerosol generating matrix entering the atomizing component to generate aerosol. Airflow flows from the external space of the aerosol generating device into the atomizing component, carrying the generated aerosol out of the aerosol generating device. During transportation, the aerosol generating device, once filled with the aerosol generating matrix, may experience increased internal pressure in the storage chamber due to vibration, or increased internal pressure due to the operation of the atomizing component. This pressure difference can cause the aerosol generating matrix in the storage chamber to be squeezed into the atomizing component, resulting in leakage of the aerosol generating matrix from the atomizing component.

[0026] In view of the above problems, this application provides an aerosol generating device to solve the technical problem of easy leakage of aerosol generating matrix.

[0027] To illustrate the technical solution of this application, the following description is provided in conjunction with specific accompanying drawings and embodiments.

[0028] Please refer to Figure 1 and Figure 2 This application provides an aerosol generating apparatus for heating an aerosol generating matrix to generate aerosols, including a housing 100 and a nozzle 200.

[0029] The housing 100 has a liquid storage chamber 110 and an atomizing gas channel 410 penetrating the liquid storage chamber 110. The liquid storage chamber 110 is used to store the aerosol generation matrix, and the atomizing gas channel 410 is connected to the liquid storage chamber 110. A suction nozzle 200 is connected to one end of the housing 100, and the suction nozzle 200 and the housing 100 form a transition cavity 300. The suction nozzle 200 has a suction channel 210, which is connected to the atomizing gas channel 410 through the transition cavity 300. The housing 100 has a first pressure relief hole 132 connecting the liquid storage chamber 110 and the transition cavity 300.

[0030] Understandably, the housing 100 houses the atomizing component 400, and the aerosol generating matrix in the liquid storage chamber 110 can enter the atomizing component 400. An atomizing air passage 410 is constructed within the atomizing component 400, and the atomizing component 400 atomizes the aerosol generating matrix entering the atomizing component 400 to generate aerosol within the atomizing air passage 410. When the aerosol generating device is suctioned, the airflow direction is: external space → atomizing air passage 410 → transition chamber 300 → suction channel 210, allowing the aerosol to flow out of the aerosol generating device.

[0031] The suction nozzle 200 is connected to one end of the housing 100. That is, the suction nozzle 200 and the housing 100 can be connected by detachable connection methods such as snap-fit ​​connection, magnetic connection, threaded connection, plug-in connection, or the suction nozzle 200 and the housing 100 can be connected by fixed connection methods such as welding, connection with adhesive (glue, tape, etc.), or connection with fasteners (rivets, screws, etc.).

[0032] Please refer to Figure 2 and Figure 3 The nozzle 200 and the housing 100 are arranged to form a transition cavity 300. That is, the housing 100 is constructed with a transition groove 120 with the opening facing the nozzle 200. The nozzle 200 covers the opening of the transition groove 120, so that the surface of the nozzle 200 facing the housing 100 and the inner wall of the transition groove 120 enclose the transition cavity 300.

[0033] The housing 100 is provided with a first pressure relief hole 132 that connects the liquid storage chamber 110 and the transition chamber 300. That is, the opening of the first pressure relief hole 132 penetrates the bottom of the transition groove 120, so that the first pressure relief hole 132 is connected to the transition chamber 300.

[0034] In the aerosol generating device provided in this application, since the nozzle 200 and the housing 100 form a transition cavity 300, the nozzle 200 is provided with a suction channel 210, which is connected to the atomizing gas channel 410 through the transition cavity 300. The housing 100 is provided with a first pressure relief hole 132 that connects the liquid storage cavity 110 and the transition cavity 300. Therefore, the liquid storage cavity 110 can be connected to the external space through the first pressure relief hole 132, the transition cavity 300 and the suction channel 210, so that the gas in the liquid storage cavity 110 can exchange with the external space through the pressure relief hole, the transition cavity 300 and the suction channel 210, so that the pressure in the liquid storage cavity 110 can be kept stable, so as to prevent the aerosol generating matrix in the liquid storage component 500 from being squeezed into the atomizing component 400 due to the increase of the internal pressure of the liquid storage cavity 110, thereby preventing the aerosol generating matrix from leaking from the atomizing component 400.

[0035] It is understandable that the first pressure relief hole 132 can also be used as an injection hole, that is, the suction nozzle 200 is detachably connected to the housing 100. The process of replenishing the aerosol generation matrix into the liquid storage chamber 110 is as follows: remove the suction nozzle 200 from the housing 100 so that the first pressure relief hole 132 is directly connected to the external space. The liquid outlet of the injection tool such as the syringe or injection needle enters the liquid storage chamber 110 through the first pressure relief hole 132. The injection tool replenishes the aerosol generation matrix into the liquid storage chamber 110. After replenishment, the suction nozzle 200 is reconnected to the housing 100.

[0036] Please refer to Figure 2 and Figure 4 In some embodiments, the housing 100 includes a top plate 130, a first side plate 140, and a seal 150. The top plate 130 is provided with an air outlet 131 and a first pressure relief hole 132, the air outlet 131 connecting the atomizing air passage 410 and the transition chamber 300. The first side plate 140 extends from the top plate 130 in a direction away from the nozzle 200. The seal 150 is connected to the first side plate 140, and the seal 150, the top plate 130, and the first side plate 140 surround to form a liquid storage chamber 110.

[0037] In the above embodiment, the first side plate 140 has a cylindrical structure, and the sealing member 150 is housed within the first side plate 140, with the sealing member 150 abutting against the inner wall of the first side plate 140, so that the sealing member 150, the top plate 130, and the first side plate 140 surround and form a liquid storage cavity 110. Optionally, the sealing member 150 is made of elastic materials such as rubber or silicone to improve the airtightness of the liquid storage cavity 110.

[0038] In the above embodiment, when the aerosol generating device is drawn in, the airflow direction is: external space → atomizing airway 410 → air outlet 131 → transition chamber 300 → suction channel 210, so that the aerosol can flow out of the aerosol generating device.

[0039] Please refer to Figure 2 In some embodiments, the air outlet 131 is connected to the atomizing air passage 410 in such a way that a portion of the atomizing component 400 is housed within the air outlet 131, allowing the atomizing air passage 410 to communicate with the air outlet 131.

[0040] In other embodiments, the housing 100 also includes a connecting portion 133 extending from the top plate 130 toward the seal 150, with an air outlet 131 passing through the connecting portion 133. A portion of the connecting portion 133 is housed within the atomizing air passage 410, allowing the atomizing air passage 410 to communicate with the air outlet 131.

[0041] Please refer to Figures 2 to 4 In some embodiments, the housing 100 further includes a second side plate 160, which extends from the top plate 130 in a direction away from the first side plate 140. The second side plate 160 and the top plate 130 form a buffer groove. A suction nozzle 200 is connected to the second side plate 160, and the suction nozzle 200 covers the opening of the transition groove 120, such that the surface of the suction nozzle 200 facing the top plate 130 and the inner wall of the transition groove 120 form a transition cavity 300. An air outlet 131 penetrates the bottom of the transition groove 120, so that the air outlet 131 can communicate with the transition cavity 300.

[0042] Please refer to Figure 2 In some embodiments, the second side plate 160 is provided with a first connecting structure 161, and the suction nozzle 200 is provided with a second connecting structure 220. The first connecting structure 161 and the second connecting structure 220 cooperate to make the suction nozzle 200 detachably connected to the housing 100.

[0043] Optionally, the first connecting structure 161 and the second connecting structure 220 cooperate to make the nozzle 200 and the housing 100 detachably connected, meaning that one of the first connecting structure 161 and the second connecting structure 220 is an internal thread and the other of the first connecting structure 161 and the second connecting structure 220 is an external thread, and the internal thread and the external thread mesh to make the nozzle 200 and the housing 100 detachably connected.

[0044] Optionally, the first connecting structure 161 and the second connecting structure 220 cooperate to make the nozzle 200 and the housing 100 detachably connected, meaning that one of the first connecting structure 161 and the second connecting structure 220 is a slot, and the other of the first connecting structure 161 and the second connecting structure 220 is a plate, and the plate is engaged in the slot, so that the nozzle 200 and the housing 100 are detachably connected.

[0045] Optionally, the first connecting structure 161 and the second connecting structure 220 cooperate to make the nozzle 200 and the housing 100 detachably connected, meaning that one of the first connecting structure 161 and the second connecting structure 220 is a magnet, and the other of the first connecting structure 161 and the second connecting structure 220 is a magnet or a ferromagnetic structural component, and the first connecting structure 161 and the second connecting structure 220 are magnetically attracted, so that the nozzle 200 and the housing 100 are detachably connected.

[0046] Please refer to Figure 2 In some embodiments, the aerosol generating device further includes a liquid storage component 500, which is housed in a liquid storage chamber 110 and is used to lock the aerosol generating matrix in the liquid storage chamber 110. The atomizing gas channel 410 passes through the liquid storage component 500.

[0047] In the above embodiment, the aerosol generating matrix is ​​locked inside the liquid storage unit 500, and is only released quantitatively when the atomizing component 400 is working. This prevents the aerosol generating matrix from flowing freely in the liquid storage chamber 110, thus preventing it from blocking the first pressure relief hole 132. This ensures that the first pressure relief hole 132 is always connected to the liquid storage chamber 110, so as not to affect the gas exchange between the liquid storage chamber 110 and the external space of the aerosol generating device through the first pressure relief hole 132. Furthermore, it also prevents the aerosol generating matrix inside the liquid storage unit 500 from leaking through the first pressure relief hole 132.

[0048] Please refer to Figure 2 In some embodiments, the top plate 130 is provided with a plurality of first support portions 134 in the direction of the seal 150, and one end of the first support portion 134 away from the top plate 130 abuts against the liquid storage member 500 so that the liquid storage member 500 and the first pressure relief hole 132 on the top plate 130 are spaced apart.

[0049] It is understandable that when the aerosol generating device is inverted (with the nozzle 200 located below the seal 150), the liquid storage unit 500 will move downwards under its own weight. In the above embodiment, by providing a first support part 134, and having one end of the first support part 134 away from the top plate 130 abut against the liquid storage unit 500, a gap is created between the liquid storage unit 500 and the first pressure relief hole 132 on the top plate 130. This prevents the liquid storage unit 500 from covering the first pressure relief hole 132, ensuring that the first pressure relief hole 132 remains connected to the liquid storage chamber 110, so as not to affect the gas exchange between the liquid storage chamber 110 and the external space of the aerosol generating device through the first pressure relief hole 132; moreover, it also prevents the aerosol generating matrix inside the liquid storage unit 500 from leaking through the first pressure relief hole 132.

[0050] In some embodiments, the end of the first support portion 134 away from the top plate 130 protrudes from the opening of the first pressure relief hole 132 that connects to the liquid storage chamber 110, thereby allowing the liquid storage component 500 to be spaced apart from the first pressure relief hole 132 on the top plate 130.

[0051] Please refer to Figure 4 In some embodiments, the first support portion 134 is annular and surrounds the first pressure relief hole 132. The first support portion 134 forms a first connecting hole 135 around the first support portion 134. One end of the first connecting hole 135 is connected to the first pressure relief hole 132, and the other end of the first connecting hole 135 away from the first connecting hole 135 is connected to the liquid storage chamber 110. A second connecting hole 136 is provided on the first support portion 134, and the second connecting hole 136 connects the first connecting hole 135 and the liquid storage chamber 110.

[0052] With the above configuration, the first pressure relief hole 132 is always connected to the liquid storage chamber 110, so as not to affect the gas exchange between the liquid storage chamber 110 and the external space of the aerosol generating device through the first pressure relief hole 132; and it can also prevent the aerosol generating matrix in the liquid storage component 500 from leaking through the first pressure relief hole 132.

[0053] Please refer to Figure 4 and Figure 5 In some embodiments, the seal 150 is provided with an air inlet 151 and a second pressure relief hole 152. The air inlet 151 is connected to the end of the atomizing air passage 410 away from the air outlet 131. The second pressure relief hole 152 is connected to the outside and the liquid storage chamber 110.

[0054] In the above embodiment, the liquid storage chamber 110 can exchange gases with the external space of the aerosol generating device through the second pressure relief hole 152. By adding the second pressure relief hole 152, the first pressure relief hole 132 and the second pressure relief hole 152 cooperate to facilitate the exchange of gas in the liquid storage chamber 110 with the gas in the external space of the aerosol generating device, so that the gas pressure in the liquid storage chamber 110 can be kept balanced, and the gas pressure in the liquid storage chamber 110 is not easy to increase, thereby preventing the aerosol generating matrix in the liquid storage chamber 110 from leaking through the atomizing gas channel 410.

[0055] In the above embodiment, when the aerosol generating device is drawn in, the airflow direction is: external space → air inlet 151 → atomizing airway 410 → air outlet 131 → transition chamber 300 → suction channel 210, so that the aerosol can flow out of the aerosol generating device.

[0056] Please refer to Figure 2 In some embodiments, an venting channel 510 is provided on the liquid storage component 500, and the venting channel 510 penetrates the liquid storage component 500 in the distribution direction of the top plate 130 and the sealing component 150.

[0057] In the above embodiment, the gas can flow in the gas passage 510, so that the gas in the space above the liquid storage component 500 and the gas in the space below the liquid storage component 500 can exchange gases, which is beneficial to the gas flow in the liquid storage chamber 110 and to balance the gas pressure in the liquid storage chamber 110.

[0058] Please refer to Figure 4 and Figure 5 In some embodiments, the sealing member 150 includes a substrate 153 and a second support portion 154. A second pressure relief hole 152 is provided on the substrate 153. The second support portion 154 is provided on the surface of the substrate 153 facing the top plate 130. An air inlet 151 passes through the second support portion 154 and the substrate 153. The end of the second support portion 154 away from the substrate 153 abuts against the surface of the liquid reservoir 500 opposite to the top plate 130, so that the liquid reservoir 500 and the second pressure relief hole 152 on the substrate 153 are spaced apart.

[0059] It is understandable that when the aerosol generating device is placed upright (with the seal 150 located below the nozzle 200), the liquid storage unit 500 will move downwards under its own weight. In the above embodiment, by providing a second support portion 154, and having one end of the second support portion 154 away from the substrate 153 abut against the surface of the liquid storage unit 500 away from the top plate 130, the liquid storage unit 500 and the second pressure relief hole 152 on the substrate 153 are spaced apart to prevent the liquid storage unit 500 from covering the second pressure relief hole 152. This ensures that the second pressure relief hole 152 is always connected to the liquid storage chamber 110, so as not to affect the gas exchange between the liquid storage chamber 110 and the external space of the aerosol generating device through the second pressure relief hole 152; moreover, it can also prevent the aerosol generating matrix in the liquid storage unit 500 from leaking through the second pressure relief hole 152.

[0060] Please refer to Figure 2 In some embodiments, the aerosol generating device further includes a liquid blocking member 600, which is mounted on the second support portion 154 and located between the second support portion 154 and the liquid storage member 500, and the liquid blocking member 600 protrudes from the outer side wall of the liquid storage member 500.

[0061] Under normal circumstances, when the liquid storage rate of the liquid storage component 500 is high, or when the aerosol generating device is shaken, some aerosol generating matrix can easily seep out of the liquid storage component 500. The seeped aerosol generating matrix will accumulate on the sealing component 150. When too much aerosol generating matrix accumulates on the sealing component 150, the aerosol generating matrix can easily leak through the second pressure relief hole 152. In the above embodiment, since the liquid blocking component 600 is located between the second support portion 154 and the liquid storage component 500, the aerosol generating matrix seeping out of the liquid storage component 500 will first accumulate on the liquid blocking component 600, thereby reducing the amount of aerosol generating matrix accumulating on the sealing component 150.

[0062] Please refer to Figure 2 In some embodiments, the liquid-blocking component 600 is spaced apart from the inner wall of the liquid storage cavity 110 to facilitate the flow of air in the liquid storage cavity 110. Therefore, the aerosol matrix that seeps out from the liquid storage component 500 will first accumulate on the liquid-blocking component 600 and then drip onto the sealing component 150.

[0063] Since the liquid-blocking component 600 protrudes from the outer wall of the liquid storage component 500, the aerosol generating matrix seeping from the liquid storage component 500 will drip from the periphery of the liquid storage component 500 onto the sealing component 150. This effectively prevents the aerosol generating matrix from directly entering the second pressure relief hole 152 from the liquid storage component 500, thus avoiding the aerosol generating matrix from blocking the second pressure relief hole 152. This ensures that the second pressure relief hole 152 remains connected to the liquid storage chamber 110, so as not to affect the gas exchange between the liquid storage chamber 110 and the external space of the aerosol generating device through the second pressure relief hole 152. Furthermore, it also prevents the aerosol generating matrix from leaking through the second pressure relief hole 152.

[0064] Please refer to Figure 2 In some embodiments, the liquid baffle 600 is provided with a communication structure 610 that corresponds to and communicates with the air passage 510.

[0065] By constructing a connecting structure 610 on the liquid baffle 600 that corresponds to and connects with the gas passage 510, the liquid baffle 600 will not affect the gas flow in the liquid storage chamber 110.

[0066] Optionally, the connecting structure 610 can be a virtual structure such as a hole or groove formed on the liquid-blocking component 600.

[0067] Please refer to Figure 4 and Figure 5 In some embodiments, the seal 150 further includes a third support portion 155, which is disposed on the surface of the substrate 153 facing the top plate 130. The second pressure relief hole 152 penetrates the third support portion 155 and the substrate 153. The end of the third support portion 155 near the top plate 130 is at a certain distance from the substrate 153, such that the opening of the second pressure relief hole 152 connecting the liquid storage chamber 110 is at a certain distance from the substrate 153. Therefore, when the aerosol generating matrix accumulates on the seal 150, the aerosol generating matrix is ​​not likely to block the second pressure relief hole 152, so that the second pressure relief hole 152 is always connected to the liquid storage chamber 110, so as not to affect the gas exchange between the liquid storage chamber 110 and the external space of the aerosol generating device through the second pressure relief hole 152; moreover, the aerosol generating matrix is ​​not likely to leak through the second pressure relief hole 152.

[0068] In the above embodiment, the second support portion 154 protrudes from the third support portion 155 in the direction toward the top plate 130. This prevents the liquid storage component 500 from covering the opening of the second pressure relief hole 152 that connects to the liquid storage chamber 110, ensuring that the second pressure relief hole 152 remains connected to the liquid storage chamber 110, so as not to affect the gas exchange between the liquid storage chamber 110 and the external space of the aerosol generating device through the second pressure relief hole 152; it also prevents the aerosol generating matrix in the liquid storage component 500 from leaking through the second pressure relief hole 152.

[0069] Please refer to Figure 4 and Figure 5 In some embodiments, the surface of the substrate 153 facing the top plate 130 is provided with a leak-proof portion 156, which is annular and surrounds the second pressure relief hole 152. The liquid storage member 500 is spaced apart from the surface of the substrate 153 facing the leak-proof portion 156.

[0070] In the above embodiment, the surface of the leak-proof part 156 facing away from the third support part 155 (second pressure relief hole 152), the substrate 153, and the inner surface of the first side plate 140 can be enclosed to form a first gathering groove 157. The surface of the leak-proof part 156 facing the third support part 155 (second pressure relief hole 152) and the substrate 153 can be enclosed to form a second gathering groove 158. The third support part 155 (second pressure relief hole 152) is located in the second gathering groove 158. The liquid blocking member 600 is located above the first gathering groove 157. After the aerosol seeping from the liquid storage member 500 generates a matrix that gathers in the liquid blocking member 600, it drips from the periphery of the liquid blocking member 600 into the first gathering groove 157. When the height of the aerosol generating matrix accumulated in the first gathering tank 157 is higher than the height of the leak-proof part 156, the aerosol generating matrix will overflow from the first gathering tank 157 and flow into the second gathering tank 158. When the height of the aerosol generating device accumulated in the second gathering tank 158 is higher than the height of the third support part 155, the aerosol generating device will flow out of the liquid storage chamber 110 through the second pressure relief hole 152. By setting the leak-proof part 156, the aerosol generating matrix can be effectively blocked from flowing to the second pressure relief hole 152, thus achieving a layer of leak prevention.

[0071] Please refer to Figure 4 and Figure 5 In some embodiments, the surface of the substrate 153 facing the top plate 130 is also provided with a dividing part 159. The dividing part 159 is disposed between the leak-proof part 156 and the third support part 155 (second pressure relief hole 152). The dividing part 159 is used to divide the second gathering groove 158 into multiple independent and nested buffer grooves. The third support part 155 (second pressure relief hole 152) is located in the innermost buffer groove 158-1.

[0072] Understandably, in the direction from the first side plate 140 to the third support portion 155 (second pressure relief hole 152), the innermost buffer groove 158-1 is furthest from the first side plate 140 (first gathering groove 157), while the outermost buffer groove 158-2 is closest to the first side plate 140 (first gathering groove 157). When the height of the aerosol generating matrix accumulated in the first gathering groove 157 is higher than the leak-proof portion 156, the aerosol generating matrix will overflow from the first gathering groove 157 and flow into the outermost buffer groove 158-2. Only when the height of the aerosol generating matrix accumulated in the outermost buffer groove 158-2 is higher than the height of the dividing portion 159 will the aerosol generating matrix flow into the buffer groove located inside the outermost buffer groove 158-2. This process continues until multiple buffer grooves are filled before the aerosol generating matrix flows to the second pressure relief hole 152, thus achieving multiple leak prevention.

[0073] For example, the dividing section 159 divides the second gathering tank 158 into two nested buffer tanks, namely the outermost buffer tank and the innermost buffer tank. When the height of the aerosol generating matrix gathered in the first gathering tank 157 is higher than the leak-proof section 156, the aerosol generating matrix will overflow from the first gathering tank 157 and flow into the outermost buffer tank 158-2. Only when the height of the aerosol generating matrix gathered in the outermost buffer tank 158-2 is higher than the height of the dividing section 159 will the aerosol generating matrix flow into the innermost buffer tank 158-1. This achieves double leak prevention.

[0074] For example, the dividing section 159 divides the second gathering tank 158 into three nested buffer tanks: the outermost buffer tank, the transition buffer tank, and the innermost buffer tank. When the height of the aerosol generating matrix gathered in the first gathering tank 157 is higher than the leak-proof section 156, the aerosol generating matrix will overflow from the first gathering tank 157 and flow into the outermost buffer tank 158-2. Only when the height of the aerosol generating matrix gathered in the outermost buffer tank 158-2 is higher than the height of the dividing section 159 will the aerosol generating matrix flow into the transition buffer tank. Only when the height of the aerosol generating matrix gathered in the transition buffer tank is higher than the height of the dividing section 159 will the aerosol generating matrix flow into the innermost buffer tank 158-1. This achieves triple leak prevention.

[0075] Please refer to Figure 5In some embodiments, the two ends of the dividing portion 159 are respectively connected to the leak-proof portion 156. Two dividing portions 159 are provided, located on opposite sides of the second pressure relief hole 152. The dividing portions 159 facing the sidewall of the third support portion 155 (second pressure relief hole 152), the substrate 153, and the leak-proof portion 156 facing the sidewall of the third support portion 155 (second pressure relief hole 152) form the innermost buffer groove 158-1. The dividing portions 159 facing away from the sidewall of the second pressure relief hole 152, the substrate 153, and the leak-proof portion 156 facing the sidewall of the second pressure relief hole 152 form the outermost buffer groove 158-2, thereby achieving double leak prevention. Optionally, the number of buffer grooves can be increased by increasing the number of dividing portions 159 to achieve multi-layer leak prevention, such as three-layer or four-layer leak prevention.

[0076] In other embodiments, the dividing portion 159 is an annular plate. The dividing portion 159 is provided and surrounds the periphery of the third support portion 155 (second pressure relief hole 152). The dividing portion 159 is located between the leak-proof portion 156 and the third support portion 155 (second pressure relief hole 152). The dividing portion 159, facing away from the sidewall of the third support portion 155 (second pressure relief hole 152), the substrate 153, and the leak-proof portion 156 facing the sidewall of the third support portion 155 (second pressure relief hole 152) form the outermost buffer groove 158-2. The dividing portion 159, facing the sidewall of the third support portion 155 (second pressure relief hole 152), and the substrate 153 form the innermost buffer groove 158-1, thus achieving double leak prevention. Optionally, the number of buffer grooves can be increased by increasing the number of dividing portions 159 to achieve multi-layer leak prevention, such as three-layer or four-layer leak prevention.

[0077] Please refer to Figure 2 In some embodiments, the aerosol generating device further includes a liquid suction member 700, which is housed in the transition cavity 300. The liquid suction member 700 is provided with an air passage 710, one end of which is connected to the atomizing air channel 410, and the other end of which is connected to the suction channel 210 away from the atomizing air channel 410.

[0078] It is understandable that when the aerosol flows into the suction channel 210 on the nozzle 200, some of the aerosol will condense into liquid droplets due to the decrease in temperature. The liquid droplets have a large gravity, so they will flow along the suction channel 210 and the atomizing air channel 410, and may leak directly out of the aerosol generating device along the atomizing air channel 410.

[0079] In the above embodiment, the liquid suction member 700 is housed in the transition cavity 300. The liquid suction member 700 can adsorb liquid droplets flowing from the suction channel 210 to the atomizing air channel 410 to prevent liquid droplets from leaking out of the aerosol generating device along the atomizing air channel 410.

[0080] Furthermore, in the above embodiment, the liquid suction member 700 can also absorb the aerosol generating matrix leaking through the first pressure relief hole 132 to prevent the aerosol generating matrix from leaking out of the atomizing air passage 410 from the aerosol generating device.

[0081] In the above embodiment, when the aerosol generating device is drawn in, the airflow direction is: external space → air inlet 151 → atomizing air channel 410 → air outlet 131 → transition chamber 300 → air passage 710 → suction channel 210, so that the aerosol can flow out of the aerosol generating device.

[0082] Please refer to Figure 2 and Figure 3 In some embodiments, a pressure relief groove 137 is constructed on the housing 100 (top plate 130). One end of the pressure relief groove 137 is connected to the first pressure relief hole 132, and the end of the pressure relief groove 137 away from the first pressure relief hole 132 is connected to the vent hole 131. The liquid suction member 700 covers the opening of the pressure relief groove 137.

[0083] Understandably, the liquid suction component 700 will adhere to the upper surface of the top plate 130 under its own weight, thereby covering the opening of the first pressure relief hole 132. In the above embodiment, one end of the pressure relief groove 137 is connected to the first pressure relief hole 132, and the end of the pressure relief groove 137 away from the first pressure relief hole 132 is connected to the vent hole 131. The liquid suction component 700 covers the opening of the pressure relief groove 137, so that the first pressure relief hole 132 can be connected to the vent hole 131 through the pressure relief groove 137. Thus, the first pressure relief hole 132 is connected to the external space of the aerosol generating device through the pressure relief groove 137, the vent hole 131, the vent 710, and the suction channel 210. The pressure relief path of the aerosol generating device is: liquid storage chamber 110 → first pressure relief hole 132 → pressure relief groove 137 → vent hole 131 → vent 710 → suction channel 210 → external space.

[0084] In the above embodiment, the pressure relief groove 137 is a through groove. One end of the pressure relief groove 137 penetrates the side wall of the first pressure relief hole 132, and the pressure relief groove 137 penetrates the side wall of the air outlet 131, so that one end of the pressure relief groove 137 is connected to the first pressure relief hole 132, and the end of the pressure relief groove 137 away from the first pressure relief hole 132 is connected to the air outlet 131.
