Description

Technical Field

[0001] This application relates to the technical field of atomization devices, and particularly to an atomizer and an atomization device. Background Art

[0002] An atomizer includes an atomization core. An atomization matrix is stored in the atomizer, and the atomization core can heat the atomization matrix to generate an aerosol. When external environmental conditions change (such as temperature or air pressure changes), the atomization matrix in the atomizer is prone to leakage. In related technologies, to reduce the risk of leakage of the atomization matrix, the atomizer adopts an oil-core separation structure. There is no atomization matrix in the atomization core before the atomizer is used. However, in this solution, the atomization core requires a long wetting waiting time when the atomizer is in use, which affects the user experience. Summary of the Invention

[0004] To solve the above technical problem, on the one hand, this application provides an atomizer. The atomizer includes a liquid storage component and an atomization component. The liquid storage component is detachably connected to the atomization component. The liquid storage component includes a first liquid storage chamber.

The support assembly and the first liquid storage housing enclose a first liquid storage cavity for storing the atomization matrix. The support assembly has a first position and a second position relative to the first liquid storage housing. The atomization component includes a second liquid storage chamber and an atomization core. The second liquid storage chamber is provided with a second liquid storage cavity. The atomization core is installed in the second liquid storage cavity. The atomization core is used to heat the atomization matrix to generate an aerosol. The atomizer has a first state in which the first liquid storage chamber is isolated from the second liquid storage chamber and a second state in which the first liquid storage chamber is in communication with the second liquid storage chamber. During the process of the atomizer converting from the first state to the second state, the atomization component can push the support assembly to move from the first position to the second position, so as to compress the internal space of the first liquid storage cavity and cause the atomization matrix in the first liquid storage cavity to be pressed into the second liquid storage cavity.

[0009] In one embodiment, the atomizer includes a mouthpiece portion, and the mouthpiece portion is connected to the first liquid storage housing; the bracket assembly includes a frame body and a connecting pipe.

The connecting pipe is fixedly connected to the frame body, and the connecting pipe is provided with a first communication port; the closing member includes a first closing portion, and the first closing portion is arranged at one end of the first clamping portion close to the mouthpiece portion. The first closing portion is movably received in the connecting pipe, and the first closing portion is configured to release the sealing of the first communication port when the atomizer is converted from the first state to the second state, so that the first liquid storage cavity communicates with the second liquid storage cavity through the first communication port; and the first closing portion is further configured to seal the first communication port again when the atomizer is converted from the second state to the first state.

[0010] In one embodiment, in the second state, at least a part of the first communication port is exposed at one end of the first closing portion away from the mouthpiece portion to release the sealing of the first communication port; and in the first state, the first closing portion seals the first communication port by blocking one end of the connecting pipe away from the mouthpiece portion.

[0029] Next, with reference to the accompanying drawings and embodiments, the present application will be further described in detail. It should be specifically noted that the following embodiments are only used to illustrate the present application, but do not limit the scope of the present application. Similarly, the following embodiments are only partial embodiments of the present application rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present application.

[0030] In the description of this application, the meaning of "a plurality of" is at least two, such as two, three, etc., unless otherwise specifically defined.

Thus, features defined with "first", "second", and "third" may explicitly or implicitly include at least one of such features. All directional indications (such as up, down, left, right, front, back...) in the embodiments of this application are only used to explain the relative positional relationship and movement conditions between components in a specific posture (as shown in the drawings). If the specific posture changes, the directional indication will also change accordingly.

[0031] Reference to "embodiment" herein means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of this application. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0032] This application provides an atomizing device. Please refer to Figure 1 , the atomizing device 500 may include an atomizer 100 and an atomizing main unit 400. The atomizing main unit 400 is electrically connected to the atomizer 100, and the atomizing main unit 400 is used to control the operation of the atomizer 100. Exemplarily, the atomizer 100 and the atomizing main unit 400 can be electrically connected through electrodes. The atomizing main unit 400 may include a battery (not shown in the figure), a circuit board (not shown in the figure), and an air flow sensor (not shown in the figure). The circuit board and the air flow sensor are both electrically connected to the battery. The air flow sensor can generate a control signal based on the user's sucking action, and the circuit board can control the conduction state between the atomizer 100 and the battery according to the control signal, so as to control the atomizer 100 to heat and atomize the atomizing matrix to generate an aerosol or stop heating. The connection between the atomizer 100 and the atomizing main unit 400 can be a fixed connection or a detachable connection such as snap connection, screw connection, adhesive connection, or magnetic attraction connection. When the connection between the atomizer 100 and the atomizing main unit 400 is a detachable connection, the atomizing main unit 400 can be used multiple times after replacing the atomizer 100, which is beneficial to reducing the user's usage cost.

[0033] Please refer to Figures 1 - 9, the atomizer 100 includes a liquid storage assembly 10 and an atomization assembly 20. The liquid storage assembly 10 is detachably connected to the atomization assembly 20. By setting the detachable connection between the liquid storage assembly 10 and the atomization assembly 20, when the atomization matrix in the liquid storage assembly 10 is less than a preset amount, the liquid storage assembly 10 can be separated from the atomization assembly 20, and the atomization assembly 20 can be used multiple times after replacing the liquid storage assembly 10, which is beneficial to reducing the user's usage cost. The liquid storage assembly 10 includes a first liquid storage chamber 12. The first liquid storage chamber 12 includes a first liquid storage housing 121 and a bracket assembly 18. The bracket assembly 18 is movably connected to one end of the first liquid storage housing 121. The bracket assembly 18 is movable relative to the first liquid storage housing 121. The bracket assembly 18 has a first position and a second position relative to the first liquid storage housing 121. Exemplarily, the bracket assembly 18 is slidably connected to the first liquid storage housing 121, and the relative position between the bracket assembly 18 and the first liquid storage housing 121 can be changed by applying a force to the bracket assembly 18. The bracket assembly 18 and the first liquid storage housing 121 enclose a first liquid storage cavity 123 for storing the atomization matrix. Storing the atomization matrix in the relatively independent first liquid storage chamber 12 can reduce the risk of atomization matrix leakage.

[0034] Please refer to Figures 2 - 4 , the atomization assembly 20 includes a second liquid storage chamber 21 and an atomization core 23. The second liquid storage chamber 21 is provided with a second liquid storage cavity 214, and the atomization core 23 is installed in the second liquid storage cavity 214. The second liquid storage cavity 214 can supply the atomization matrix to the atomization core 23. The atomization core 23 is used to heat and atomize the atomization matrix to generate an aerosol. The atomizer 100 has a first state in which the first liquid storage chamber 12 is isolated from the second liquid storage chamber 21 and a second state in which the first liquid storage chamber 12 is in communication with the second liquid storage chamber 21. The second state can be the state during the use of the atomizer 100. The first state can be the state before the atomizer 100 is enabled or the state during the period of inactivity after being enabled. During the process of the atomizer 100 transitioning from the first state to the second state, the atomization assembly 20 can push the bracket assembly 18 to move from the first position to the second position to compress the internal space of the first liquid storage cavity 123, and cause the atomization matrix in the first liquid storage cavity 123 to be pressed into the second liquid storage cavity 214 under pressure. By setting that the atomization assembly 20 can communicate the first liquid storage chamber 12 with the second liquid storage chamber 21 during the connection with the liquid storage assembly 10 and push the bracket assembly 18 to move to compress the internal space of the first liquid storage cavity 123, the bracket assembly 18 can press the atomization matrix in the first liquid storage cavity 123 into the second liquid storage cavity 214, thereby increasing the flow rate of the atomization matrix when the atomization assembly 20 is connected to the liquid storage assembly 10, and reducing the wetting waiting time of the atomization core 23.

[0035] The liquid storage assembly 10 can be a one-time activation type liquid storage assembly. In one embodiment, a sealing film (not shown in the figure) can be provided on the bracket assembly 18, and the sealing film seals the first liquid storage cavity 123; correspondingly, the second liquid storage bin 21 can be provided with a spike portion (not shown in the figure). During the connection process of the atomization assembly 20 and the liquid storage assembly 10, the spike portion pierces the sealing film to release the seal on the first liquid storage cavity 123, the first liquid storage cavity 123 communicates with the second liquid storage cavity 214, and the spike portion (or the second liquid storage bin 21) can push the bracket assembly 18 to move to compress the internal space of the first liquid storage cavity 123, so that the bracket assembly 18 can press the atomization matrix in the first liquid storage cavity 123 into the second liquid storage cavity 214, thereby increasing the flow rate of the atomization matrix when the liquid storage assembly 10 is activated, and the wetting waiting time of the atomization core 23 can be reduced. When the atomization matrix in the first liquid storage cavity 123 is less than a preset amount, the liquid storage assembly 10 can be separated from the atomization assembly 20, and the atomization assembly 20 can be used multiple times after replacing the liquid storage assembly 10, which is beneficial to reducing the user's usage cost.

[0036] The liquid storage assembly 10 can also be a multi-time activation type liquid storage assembly. Please refer to Figure 2 , Figure 3 , Figure 10, in one embodiment, the liquid storage assembly 10 includes a closure member 13. The closure member 13 is movably connected to the bracket assembly 18, and the closure member 13 has a sealed position and an open position relative to the bracket assembly 18. The closure member 13 can seal the first liquid storage chamber 123 to prevent the atomization matrix in the first liquid storage chamber 123 from leaking. Exemplarily, the closure member 13 is slidably connected to the bracket assembly 18, so that the closure member 13 can move between the sealed position and the open position relative to the bracket assembly 18 to change the liquid path communication state between the liquid storage assembly 10 and the atomization assembly 20. The atomization assembly 20 includes a connecting member 22. The connecting member 22 is disposed in the second liquid storage bin 21. The connecting member 22 can be connected to the second liquid storage bin 21 as an integral part or can be assembled and connected to the second liquid storage bin 21. During the process of the atomizer 100 transitioning from the first state to the second state, the connecting member 22 can push the closure member 13 from the sealed position to the open position, so that the closure member 13 releases the seal on the first liquid storage chamber 123, and the first liquid storage chamber 123 can communicate with the second liquid storage chamber 214 through the connecting member 22, and the first liquid storage chamber 123 can supply the atomization matrix to the second liquid storage chamber 214. During the activation process of the liquid storage assembly 10, it can be the second liquid storage bin 21 that pushes the bracket assembly 18 to move. Alternatively, the connecting member 22 can push the bracket assembly 18 to move. By setting the connecting member 22 to push the bracket assembly 18 to move, on the one hand, pushing the bracket assembly 18 to move through the connecting member 22 can compress the internal space of the first liquid storage chamber 123, and the bracket assembly 18 presses the atomization matrix in the first liquid storage chamber 123 into the second liquid storage chamber 214, thereby increasing the flow rate of the atomization matrix when the atomization assembly 20 is connected to the liquid storage assembly 10, and the wetting waiting time of the atomization core 23 can be reduced; on the other hand, compared with the second liquid storage bin 21 pushing the bracket assembly 18 to move, the second liquid storage bin 21 does not need to abut against the bracket assembly 18, and the second liquid storage bin 21 does not need to be inserted into the first liquid storage housing 121, so that the volume of the second liquid storage bin 21 is not limited by the first liquid storage housing 121, and the component arrangement inside the second liquid storage bin 21 is more flexible. During the process of the atomizer 100 transitioning from the second state to the first state, the connecting member 22 is coupled to the closure member 13 and pulls the closure member 13 from the open position to the sealed position, so that the closure member 13 seals the first liquid storage chamber 123 again, and the closure member 13 seals the atomization matrix in the first liquid storage chamber 123. By setting the connecting member 22 to drive the closure member 13 to move, the closure member 13 can release the seal on the first liquid storage chamber 123 when the atomization assembly 20 is connected to the liquid storage assembly 10, and seal the atomization matrix in the first liquid storage chamber 123 again when the atomization assembly 20 is separated from the liquid storage assembly 10, so that the liquid storage assembly 10 can be activated multiple times, and the atomization assembly 20 does not need to be in long-term communication with the liquid storage assembly during the period of inactivity after the atomizer 100 is enabled, thereby preventing the atomization matrix from leaking from the atomization assembly 20.

[0037] Please refer to Figure 2 , Figure 3, in one embodiment, the atomization core 23 includes a heating element 231, a liquid guiding element 232, and an atomization tube 233. The liquid guiding element 232 is used to transfer the atomization matrix to the heating element 231, and the heating element 231 is used to generate heat when powered on. The heating element 231 heats the atomization matrix to atomize it. Exemplarily, the liquid guiding element 232 is a fiber cotton, the liquid guiding element 232 is wrapped around the outer periphery of the heating element 231, and the liquid guiding element 232 is at least partially accommodated in the atomization tube 233, so that the heating element 231, the liquid guiding element 232, and the atomization tube 233 form a relatively independent module, and then are assembled into the second liquid storage cavity 214 through the atomization tube 233, realizing the modular assembly of the atomization core 23, which can improve production efficiency.

[0038] In one embodiment, during each process of the atomizer 100 transitioning from the first state to the second state, the connecting member 22 can push the closing member 13 from the sealed position to the open position, so that the closing member 13 releases the seal on the first liquid storage cavity 123. At the same time, the connecting member 22 can also push the bracket assembly 18 from the first position to the second position. During the separation process of the atomization assembly 20 and the liquid storage assembly 10, the closing member 13 is configured to be coupled with the bracket assembly 18 and drive the bracket assembly 18 to return from the second position to the first position under the action of the connecting member 22. With such a setting, when the atomizer 100 is restarted after being paused, the connecting member 22 can push the bracket assembly 18 to move during the process of the atomization assembly 20 and the liquid storage assembly 10 being connected again, thereby increasing the flow rate of the atomization matrix when the atomization assembly 20 and the liquid storage assembly 10 are connected, and reducing the wetting waiting time of the atomization core 23.

[0039] Please refer to Figures 2 - 4 , the bracket assembly 18 includes a bracket 16 and a first seal 122. The first seal 122 seals between the first liquid storage housing 121 and the bracket 16. The first seal 122, the first liquid storage housing 121, and the bracket 16 enclose to form a first liquid storage cavity 123. The materials of the first liquid storage housing 121 and the bracket 16 can be plastic, so that the first liquid storage chamber 12 has higher strength. The first seal 122 can be made of a material with certain elastic deformation ability such as silica gel or rubber. When the first seal 122 is assembled into the liquid storage assembly 10 with an interference fit, the first seal 122 undergoes elastic deformation, so that the first seal 122 can seal the gap between the first liquid storage housing 121 and the bracket 16, thereby enhancing the tightness of the first liquid storage cavity 123 and further preventing the leakage of the atomization matrix.

[0040] In one embodiment, during the first process of the atomizer 100 transitioning from the first state to the second state, the connecting member 22 can push the bracket assembly 18 from the first position to the second position. Please refer to Figure 6, the first liquid storage chamber 12 includes a first limiting portion 173, and the first limiting portion 173 is connected to the first liquid storage housing 121. The first limiting portion 173 may be directly connected to the first liquid storage housing 121, or may be indirectly connected to the first liquid storage housing 121 through other components. In the second state, the first limiting portion 173 abuts against the bracket assembly 18, and the first limiting portion 173 can limit the bracket assembly 18 from moving from the second position to the first position. With such a setting, during the process of the atomizer 100 converting from the second state to the first state, the closing member 13 will not drive the bracket assembly 18 to return from the second position to the first position. Since the bracket assembly 18 will not move back and forth between the first position and the second position multiple times, it is possible to prevent wear and damage of the first sealing member 122 located between the bracket 16 and the first liquid storage housing 121, thereby reducing the risk of atomization matrix leakage.

[0041] In one embodiment, one of the closing member 13 and the connecting member 22 includes a magnetic member (such as a permanent magnet), and the other includes a mating member (such as a permanent magnet or a magnetizable metal member). The magnetic member forms a magnetic attraction fit with the mating member during the process of the atomizer 100 converting from the first state to the second state, so that the connecting member 22 is coupled to the closing member 13 during the process of the atomizer 100 converting from the second state to the first state, and pulls the closing member 13 to move synchronously, thereby sealing the atomization matrix in the first liquid storage cavity 123 again, so that the atomization assembly 20 can be not in long-term communication with the liquid storage assembly 10 when the atomizer 100 is not in use, thereby preventing the atomization matrix from leaking from the atomization assembly 20.

[0042] In one embodiment, as Figure 5 , Figure 10 shown, the closing member 13 includes a first clamping portion 131, and the connecting member 22 includes a second clamping portion 221. The second clamping portion 221 is configured to form a clamping fit with the first clamping portion 131 during the process of the atomizer 100 converting from the first state to the second state, so that the connecting member 22 is coupled to the closing member 13 during the process of the atomizer 100 converting from the second state to the first state, and pulls the closing member 13 to move synchronously, thereby sealing the atomization matrix in the first liquid storage cavity 123, so that the atomization assembly 20 can be not in long-term communication with the liquid storage assembly 10 when the atomizer 100 is not in use, and can prevent the atomization matrix from leaking from the atomization assembly 20. By setting the second clamping portion 221 and the first clamping portion 131 to be clamped and connected, since at least part of the clamping portions can be integrally formed on the closing member 13 and the connecting member 22 respectively, it is beneficial to simplify the structures of the closing member 13 and the connecting member 22, thereby reducing the cost.

[0043] One of the first engaging portion 131 and the second engaging portion 221 may include a spring pin, and the other is provided with a card slot. The spring pin can be elastically deformed during the connection or separation of the atomization component 20 and the liquid storage component 10, so that the spring pin is engaged with the card slot or separated from the card slot, thereby facilitating the formation of a snap-fit or separation between the second engaging portion 221 and the first engaging portion 131.

[0044] Please refer to Figure 10 , Figure 11 , in an embodiment, one of the first engaging portion 131 and the second engaging portion 221 includes a first elastic portion 225 and a first abutting portion 226, and the other is provided with a snap position 135. For example, the first engaging portion 131 includes a first elastic portion 225 and a first abutting portion 226, and the second engaging portion 221 is provided with a snap position 135; or, the second engaging portion 221 includes a first elastic portion 225 and a first abutting portion 226, and the first engaging portion 131 is provided with a snap position 135. In the figure, the case where the first engaging portion 131 is provided with a snap position 135 is taken as an example for illustration. The first elastic portion 225 extends along the moving direction of the closing member 13, and the first abutting portion 226 protrudes from one side of the first elastic portion 225 perpendicular to the moving direction. The first abutting portion 226 may protrude from the outside or the inside of the first elastic portion 225 perpendicular to the moving direction. The angle between the first elastic portion 225 and the moving direction of the closing member 13 and the angle between the first abutting portion 226 and the first elastic portion 225 can be adjusted within a certain range (for example, 5°-10°) as needed. The snap position 135 may be a snap hole or a snap groove. The first elastic portion 225 is configured to be elastically deformed during the conversion between the first state and the second state, so that the first abutting portion 226 is engaged with the snap position 135 or separated from the snap position 135, thereby facilitating the formation of a snap-fit or separation between the second engaging portion 221 and the first engaging portion 131. Since the first elastic portion 225 and the first abutting portion 226 can be integrally formed on the closing member 13 or the connecting member 22, it is beneficial to simplify the structure of the closing member 13 or the connecting member 22, thereby reducing costs.

[0045] The first engaging portion 131 and the second engaging portion 221 may be provided with a guiding surface, and the guiding surface may be an inclined surface provided obliquely. The guiding surface is used to guide the first abutting portion 226 to be engaged with the snap position 135 or to guide the first abutting portion 226 to be separated from the snap position 135, so that it is more labor-saving to form a snap-fit or separation between the second engaging portion 221 and the first engaging portion 131, which is beneficial to improving the user experience.

[0046] Please refer to Figure 2 , Figure 3, in one embodiment, the atomizer 100 includes a mouthpiece portion 11, and the mouthpiece portion 11 is connected to the first liquid storage housing 121. The mouthpiece portion 11 is used for the user to perform a suction action. The mouthpiece portion 11 can be integrally connected to the first liquid storage housing 121 or assembled and connected to the first liquid storage housing 121. The bracket 16 may be provided with a hole for accommodating the closure member 13 and allowing the connecting member 22 to pass through. At this time, the dimension of the bracket 16 in the moving direction of the closure member 13 is greater than the moving stroke of the closure member 13. Or, as Figure 3 , Figure 5 , Figure 8 , Figure 9 shown, the bracket 16 includes a frame body 161 and a connecting pipe 162. The frame body 161 is movably connected to one end of the first liquid storage housing 121 away from the mouthpiece portion 11. The first liquid storage cavity 123 is located between the first liquid storage housing 121 and the frame body 161. The connecting pipe 162 is fixedly connected to the frame body 161. The closure member 13 is movably accommodated in the connecting pipe 162. By providing the connecting pipe 162 for accommodating the closure member 13, it is only necessary that the dimension of the connecting pipe 162 in the moving direction of the closure member 13 is greater than the moving stroke of the closure member 13, and there is no need to increase the overall dimension of the bracket 16, which is beneficial to reducing the volume of the liquid storage assembly 10. The number of the connecting pipes 162 can be one or more, and the number of the connecting members 22 is the same as the number of the connecting pipes 162. Each connecting member 22 is provided corresponding to one connecting pipe 162. The connecting pipe 162 can be integrally connected to the frame body 161 or assembled and connected to the frame body 161.

[0047] Please refer to Figure 5 , Figure 7 , Figure 9 , the connecting pipe 162 is provided with a first communication port 166. The first communication port 166 can be a through hole or a notch. The number of the first communication ports 166 can be one or more. The closure member 13 includes a first closure portion 132. The first closure portion 132 is disposed at one end of the first clamping portion 131 close to the mouthpiece portion 11. The first closure portion 132 is movably accommodated in the connecting pipe 162. By accommodating the first closure portion 132 in the connecting pipe 162, the connecting pipe 162 can limit the lateral displacement of the first closure portion 132, so that the first closure portion 132 can move more stably. The first closure portion 132 is configured to release the sealing of the first communication port 166 when the atomizer 100 is converted from the first state to the second state, so that the first liquid storage cavity 123 communicates with the second liquid storage cavity 214 through the first communication port 166; and the first closure portion 132 is further configured to seal the first communication port 166 again when the atomizer 100 is converted from the second state to the first state. A third sealing member 138 may be sleeved on the outer wall of the first closure portion 132 to seal the gap between the first closure portion 132 and the connecting pipe 162.

[0048] Please refer to Figure 3 ,Figure 4 In one embodiment, the liquid storage assembly 10 includes a first air duct 15. The first air duct 15 is received in the first liquid storage housing 121. One end of the first air duct 15 is inserted into the first seal 122, and the other end is communicated with the mouthpiece 11, so that the aerosol can be transmitted to the mouthpiece 11 through the first air duct 15. The first air duct 15 can be integrally connected to the first liquid storage housing 121 or assembled and connected to the first liquid storage housing 121.

[0049] In one embodiment, as Figures 2 - 4 shown, the second liquid storage chamber 21 includes a second liquid storage housing 211, a second bottom cover 212 and a second seal 213. The second liquid storage housing 211 and the second bottom cover 212 enclose a second liquid storage cavity 214. The second seal 213 is sealed between the second liquid storage housing 211 and the second bottom cover 212 to enhance the tightness of the second liquid storage cavity 214. The atomization assembly 20 further includes a second air duct 24, a liquid storage member 25, a second liquid absorbing member 26 and an electrode 27. The second air duct 24 is connected to the second liquid storage housing 211. The second air duct 24 can be integrally connected to the second liquid storage housing 211 or assembled and connected to the second liquid storage housing 211. When the atomization assembly 20 is connected to the liquid storage assembly 10, the second air duct 24 communicates the atomization core 23 with the first air duct 15, so that the aerosol can be transmitted to the mouthpiece 11 through the second air duct 24 and the first air duct 15. The liquid storage member 25 is installed in the second liquid storage cavity 214. A corresponding through hole for the second air duct 24 to pass through may be provided on the bracket 16. After the second air duct 24 passes through the bracket 16, it can be butt-connected and communicated with the first air duct 15. The liquid storage member 25 is a porous medium, such as fiber cotton. The liquid storage member 25 can adsorb the atomization matrix, so that the atomization matrix in the second liquid storage cavity 214 is not easily leaked. The liquid storage member 25 contacts the atomization core 23, and the liquid storage member 25 is used to supply the atomization matrix to the atomization core 23. The second liquid absorbing member 26 is disposed between the second seal 213 and the second bottom cover 212. The second liquid absorbing member 26 is used to adsorb the atomization matrix oozing from the atomization core 23 to prevent the atomization matrix from leaking. The electrode 27 is installed on the second bottom cover 212. The electrode 27 is electrically connected to the atomization core 23, so that the atomization core 23 can be electrically connected to the atomization main body 400 through the electrode 27.

[0050] The connecting pipe 162 can be connected to the frame body 161 at one end and extend into the interior of the first liquid storage chamber 123 at the other end. The first communication port 166 can be provided on the side wall of the connecting pipe 162, and the first communication port 166 communicates with the first liquid storage chamber 123. The first closing portion 132 is tubular, and through holes are provided in a partial area of the side wall of the first closing portion 132. When the through hole on the side wall of the first closing portion 132 moves to correspond to the first communication port 166, the first closing portion 132 releases the sealing of the first communication port 166; when the through hole on the side wall of the first closing portion 132 moves to be misaligned with the first communication port 166, the area of the first closing portion 132 other than the area where the through hole is provided can seal the first communication port 166.

[0051] In one embodiment, as Figure 7 、 Figure 9 shown, in the second state, that is, when the closing member 13 moves from the sealing position to the opening position, the first communication port 166 is at least partially exposed at the end of the first closing portion 132 away from the suction nozzle portion 11 to release the sealing of the first communication port 166; and in the first state, that is, when the closing member 13 moves from the opening position to the sealing position, the first closing portion 132 seals the first communication port 166 by blocking the end of the connecting pipe 162 away from the suction nozzle portion 11. When the closing member 13 is in the sealing position, the first closing portion 132 is provided to block the connecting pipe 162 to seal the first communication port 166. Since the side wall of the first closing portion 132 can be not provided with holes, it is beneficial to reduce the size of the first closing portion 132, thereby reducing the volume of the liquid storage assembly 10.

[0052] As described above, through holes can be provided in a partial area of the side wall of the first closing portion 132. When the through hole on the side wall of the first closing portion 132 moves to correspond to the first communication port 166, the first closing portion 132 releases the sealing of the first communication port 166. The area of the first closing portion 132 other than the area where the through hole is provided (for example, the end of the first closing portion 132 away from the suction nozzle portion 11) can block the end of the connecting pipe 162 away from the suction nozzle portion 11 to prevent the atomization matrix from leaking from the connecting pipe 162. Or, please refer to Figure 5 、 Figure 7 、 Figure 11, in one embodiment, the connecting member 22 includes a second closing portion 222. The second closing portion 222 is disposed at an end of the second engaging portion 221 away from the nozzle portion 11. The second closing portion 222 is provided in the second liquid storage chamber 21 and communicates with the second liquid storage cavity 214. The second closing portion 222 can be connected to the second liquid storage chamber 21 as an integral part, or can be assembled and connected to the second liquid storage chamber 21. The second engaging portion 221 is provided with a second communication port 224. The second communication port 224 can be a through hole or a notch. The number of the second communication ports 224 can be one or more. By providing the second communication port 224 in the second engaging portion 221, the lateral stiffness of the second engaging portion 221 can be reduced, so as to facilitate the second engaging portion 221 to form a clamping fit with the first engaging portion 131 when subjected to an external action. In the second state, that is, when the closing member 13 moves from the sealing position to the opening position, the first liquid storage cavity 123 communicates with the second liquid storage cavity 214 through the first communication port 166 and the second communication port 224, and the second closing portion 222 plugs one end of the connecting pipe 162 away from the nozzle portion 11. A fourth sealing member 227 can be sleeved on the outer wall of the second closing portion 222 to seal the gap between the second closing portion 222 and the connecting pipe 162. When the closing member 13 is in the opening position, by providing the second closing portion 222 to plug the connecting pipe 162 to seal the connecting pipe 162, compared with plugging one end of the connecting pipe 162 away from the nozzle portion 11 in an area other than opening a through hole in the first closing portion 132, since the side wall of the first closing portion 132 can be not provided with holes, it is beneficial to reduce the size of the first closing portion 132, thereby reducing the volume of the liquid storage assembly 10.

[0053] In one embodiment, as Figure 5 , Figure 11 shown, the connecting member 22 further includes a liquid guiding pipe 223. One end of the liquid guiding pipe 223 is connected to the second closing portion 222, and the other end extends into the second liquid storage chamber 21. The second closing portion 222 communicates with the second liquid storage cavity 214 through the liquid guiding pipe 223. By providing the second closing portion 222 to communicate with the second liquid storage cavity 214 through the liquid guiding pipe 223 and the liquid guiding pipe 223 extends into the second liquid storage chamber 21, the atomization matrix in the first liquid storage cavity 123 can be transmitted to the vicinity of the atomization core 23 through the liquid guiding pipe 223, which is beneficial to timely supplement the atomization matrix to the atomization core 23.

[0054] Please refer to Figure 7 、 Figure 9, in one embodiment, the first liquid storage chamber 12 includes a second limiting portion 163, and the second limiting portion 163 is connected to one end of the connecting pipe 162 close to the nozzle portion 11. The closing member 13 includes a mating portion 133, and the mating portion 133 is connected to one end of the first closing portion 132 close to the nozzle portion 11. In the first state, that is, when the atomization assembly 20 is separated from the liquid storage assembly 10, the second limiting portion 163 can abut against the mating portion 133, so that the first closing portion 132 seals one end of the connecting pipe 162 away from the nozzle portion 11. Setting the second limiting portion 163 to limit the displacement of the mating portion 133 when the atomization assembly 20 is separated from the liquid storage assembly 10 can prevent the first closing portion 132 from being pulled out of the connecting pipe 162 when the second engaging portion 221 is separated from the first engaging portion 131, so that the first closing portion 132 seals one end of the connecting pipe 162 away from the nozzle portion 11, thereby preventing the atomization matrix from leaking from the connecting pipe 162.

[0055] One end of the connecting pipe 162 away from the nozzle portion 11 can be connected to the frame body 161. At this time, one end of the connecting pipe 162 close to the nozzle portion 11 extends into the first liquid storage cavity 123. The first communication port 166 can be arranged on the side wall of the connecting pipe 162, and the first communication port 166 communicates with the first liquid storage cavity 123. Or, in one embodiment, as Figure 7 , Figure 9 shown, the second limiting portion 163 is connected between one end of the connecting pipe 162 close to the nozzle portion 11 and the frame body 161, and the first communication port 166 is arranged at one end of the connecting pipe 162 connected to the frame body 161. The frame body 161 is provided with a third communication port 167, and the third communication port 167 communicates the first communication port 166 with the first liquid storage cavity 123. Setting the first communication port 166 to communicate with the first liquid storage cavity 123 through the third communication port 167 on the frame body 161, since the size of the frame body 161 is larger, the opening method of the third communication port 167 is more flexible. For example, the third communication port 167 can be arranged along the outer periphery of the frame body 161, which is beneficial to increasing the opening size of the third communication port 167, so that the atomization matrix in the first liquid storage cavity 123 can flow more smoothly to the second liquid storage cavity 214 when being pressed by the bracket assembly 18, thereby increasing the flow rate of the atomization matrix when the atomization assembly 20 is connected to the liquid storage assembly 10, and reducing the wetting waiting time of the atomization core 23.

[0056] Holes or grooves can be formed on the second limiting portion 163, and the hole wall or groove wall can abut against the mating portion 133 to prevent the first closing portion 132 from being pulled out of the connecting pipe 162 when the second engaging portion 221 is separated from the first engaging portion 131. Or, the second limiting portion 163 protrudes from the inner wall of the connecting pipe 162, and the mating portion 133 can include a spring needle, and the spring needle can generate elastic deformation during the process of the mating portion 133 being inserted into the connecting pipe 162, so that the spring needle moves from one side of the second limiting portion 163 to the other side, thereby facilitating the assembly of the closing member 13.

[0057] In one embodiment, as Figure 7 , Figure 10 shown, the mating portion 133 includes a second elastic portion 136 and a second abutting portion 137. The second elastic portion 136 is connected to one end of the first closing portion 132 close to the nozzle portion 11, and the second abutting portion 137 protrudes from the outer wall of the second elastic portion 136. The second elastic portion 136 is configured to be elastically deformed during the process of passing through the connecting pipe 162, so that the second abutting portion 137 can be received in the third communication port 167 through the connecting pipe 162, thereby facilitating the assembly of the closure 13. In addition, since the second elastic portion 136 and the second abutting portion 137 can be integrally formed on the connecting pipe 162, it is beneficial to simplify the structure of the closure 13, thereby reducing costs.

[0058] Please refer to Figure 5 , Figures 7 - 10 , in one embodiment, the bracket 16 includes a third limiting portion 164. One end of the third limiting portion 164 can be connected to the inner wall of the third communication port 167, that is, the third limiting portion 164 can be a protrusion or flange protruding from the inner wall of the third communication port 167. When the closure 13 moves from the sealed position to the open position, the first closing portion 132 abuts against the third limiting portion 164, so that the connecting member 22 can push the bracket assembly 18 to move through the closure 13 during the initial connection of the atomization assembly 20 and the liquid storage assembly 10. Or, as Figure 8 , Figure 9 shown, both opposite ends of the third limiting portion 164 are connected to the inner wall of the third communication port 167. The third limiting portion 164 is provided across the third communication port 167, so that the frame body 161 can provide support for both ends of the third limiting portion 164. Compared with single-sided support, the risk of the third limiting portion 164 being damaged by force can be reduced. The closure 13 includes a third abutting portion 134. One end of the third abutting portion 134 is connected to the first closing portion 132, and the extending dimension of the other end of the third abutting portion 134 in the direction of the nozzle portion 11 is greater than the extending dimension of the second elastic portion 136 in the direction of the nozzle portion 11, as Figure 7 , Figure 10 shown. When the closure 13 moves from the sealed position to the open position, the third abutting portion 134 abuts against the third limiting portion 164, so that the connecting member 22 can push the bracket assembly 18 to move through the closure 13 during the initial connection of the atomization assembly 20 and the liquid storage assembly 10. The extending dimension of the third abutting portion 134 in the direction of the nozzle portion 11 is set to be greater than the extending dimension of the second elastic portion 136 in the direction of the nozzle portion 11, so that the second elastic portion 136 does not contact the third limiting portion 164 during the process of the closure 13 pushing the bracket assembly 18 to move, thereby reducing the risk of the second elastic portion 136 being damaged by pressure.

[0059] In one embodiment, asFigure 2 , Figure 6 , Figure 12 As shown in Figure 2 , Figure 6 , and Figure 12 , the first liquid storage chamber 12 includes a first bottom cover 17. The first bottom cover 17 is connected to one end of the first liquid storage housing 121 away from the nozzle portion 11. The first bottom cover 17 and the first liquid storage housing 121 define a moving space for the bracket assembly 18. The first bottom cover 17 can limit the maximum stroke of the bracket assembly 18 being pulled out by the connecting member 22, preventing it from disengaging from the first liquid storage housing 121. The first bottom cover 17 has corresponding through holes for the connecting member 22 and the second air duct 24 to pass through. Exemplarily, the first bottom cover 17 can be snap-connected to the first liquid storage housing 121. As mentioned above, the first limiting portion 173 can be directly connected to the first liquid storage housing 121 or indirectly connected to the first liquid storage housing 121 through other components. For example, the first limiting portion 173 can be indirectly connected to the first liquid storage housing 121 through the first bottom cover 17. The first bottom cover 17 includes a cover body 171 and a third elastic portion 172. The cover body 171 is connected to one end of the first liquid storage housing 121 away from the nozzle portion 11. One end of the third elastic portion 172 is connected to the cover body 171, and the other end is a free end extending towards the nozzle portion 11. The first limiting portion 173 is provided on one side of the third elastic portion 172. The bracket 16 includes a fourth abutting portion 165, and the fourth abutting portion 165 is connected to one end of the frame body 161 away from the nozzle portion 11. During the connection process of the atomization assembly 20 and the liquid storage assembly 10, the fourth abutting portion 165 moves from the side of the first limiting portion 173 away from the nozzle portion 11 to the side of the first limiting portion 173 close to the nozzle portion 11. During the separation process of the atomization assembly 20 and the liquid storage assembly 10, the fourth abutting portion 165 abuts against the first limiting portion 173 to limit the movement of the bracket 16. By arranging the first limiting portion 173 on the third elastic portion 172, since one end of the third elastic portion 172 is a free end, during the process of the fourth abutting portion 165 moving from the side of the first limiting portion 173 away from the nozzle portion 11 to the side of the first limiting portion 173 close to the nozzle portion 11, the third elastic portion 172 can undergo elastic deformation, thereby reducing the resistance received by the bracket assembly 18 during the connection process of the atomization assembly 20 and the liquid storage assembly 10, making the movement of the bracket assembly 18 more labor-saving and improving the user experience.

[0060] Please refer to Figure 6 , Figure 8 , Figure 12, in one embodiment, the frame body 161 is provided with ventilation holes 168. When the atomization assembly 20 is connected to the liquid storage assembly 10, the first liquid storage cavity 123 can communicate with the external space of the atomizer 100 through the ventilation holes 168. With such a setting, the air pressure in the first liquid storage cavity 123 can be kept balanced with the external air pressure, thereby reducing the risk of leakage of the atomization matrix in the first liquid storage cavity 123. The first bottom cover 17 includes a clamping portion 174. One end of the clamping portion 174 is connected to the cover body 171, and the other end is a free end extending towards the mouthpiece portion 11. The liquid storage assembly 10 includes a first liquid absorbing member 14, and the first liquid absorbing member 14 is clamped between the third elastic portion 172 and the clamping portion 174. Since one ends of both the third elastic portion 172 and the clamping portion 174 are free ends, the third elastic portion 172 and the clamping portion 174 can undergo elastic deformation when subjected to an external force, making it more convenient to assemble the first liquid absorbing member 14 between the third elastic portion 172 and the clamping portion 174. The first liquid absorbing member 14 is arranged corresponding to the ventilation holes 168. The first liquid absorbing member 14 can adsorb the atomization matrix oozing out from the ventilation holes 168, thereby further reducing the risk of leakage of the atomization matrix.

[0061] The above are only some embodiments of the present application, and thus do not limit the protection scope of the present application. Any equivalent device or equivalent process transformation made by using the specification and drawings of the present application, or directly or indirectly applied in other related technical fields, shall equally be included in the patent protection scope of the present application.
