[0045] Atomization device 10 includes shell assembly 11, atomization assembly 15 and activation member 13, wherein shell assembly 11 is provided with atomization pipeline 114 and liquid storage space 120, and liquid storage space 120 includes first liquid storage cavity 121 and second liquid storage cavity 122, and first liquid storage cavity 121 and second liquid storage cavity 122 are communicated by liquid supply hole 123.First liquid storage cavity 121 and second liquid storage cavity 122 can be integrated structure, or can be split structure.

[0047] In an embodiment, the housing 111 and the liquid tank 113 can be an integrated structure to reduce the assembly of parts and ensure the integrity of the atomization device 10. In an embodiment, the housing 111 and the liquid tank 113 can be a split structure, and the liquid tank 113 is detachably fixedly connected with the housing 111, so as to facilitate replacement of the liquid tank 113 filled with atomized substrates of different flavors to meet the needs of users for different flavors.

[0048] The housing 111 is formed with a suction nozzle 117, which can be used for a user to inhale, and the suction nozzle 117 is in communication with the atomization pipeline 114. The atomization pipeline 114 can be formed by segmentally connecting a plurality of components or integrally formed, and at least part of the structure of the atomization pipeline 114 is located in the second liquid storage cavity 122. In an embodiment, the atomization pipeline 114 adopts a segmented structure, and the atomization pipeline 114 includes a first atomization segment 1141, a second atomization segment 1142, and a third atomization segment 1143. The housing 111 is provided with an airway tube 115 and a first sealing member 116, and the atomization support 112, the first sealing member 116, and the airway tube 115 are sequentially connected in the air outlet direction. The airway tube 115 is formed with the first atomization segment 1141 of the atomization pipeline 114, the first sealing member 116 is formed with the second atomization segment 1142 of the atomization pipeline 114, and the atomization support 112 is formed with the third atomization segment 1143 of the atomization pipeline 114. The first sealing member 116, the atomization support 112, and the housing 111 enclose the second liquid storage cavity 122, the third atomization segment 1143 formed by the atomization support 112 is located in the second liquid storage cavity 122, the first atomization segment 1141 and the second atomization segment 1142 formed by the airway tube 115 and the first sealing member 116 are located outside the second liquid storage cavity 122, the airway tube 115 is integrally formed with the housing 111 and the suction nozzle 117, and the first sealing member 116 seals and connects the airway tube 115 and the atomization support 112 to avoid leakage of the atomized substrate from the airway tube 115. In other embodiments, the atomization pipeline 114 can be integrally formed, the housing 111 and the atomization support 112 directly enclose the second liquid storage cavity 122, the atomization pipeline 114 is entirely placed in the second liquid storage cavity 122, and the atomization pipeline 114 can be integrally formed with the suction nozzle 117 and the housing 111. In this way, the assembly of parts can be reduced and the integrity of the atomization device 10 can be ensured.

[0049] The atomization assembly 15 is configured to heat the atomization substrate and generate aerosol, and includes a liquid guide 151 and a heating element 152 arranged in the atomization channel 114. The liquid guide 151 is a porous medium, such as fibrous cotton, and can absorb the atomization substrate to transfer the atomization substrate to the heating element 152. The heating element 152 is connected with an electrode, and the heating element 152 can be electrically connected with the battery 23 in the power supply device 20 through the electrode to provide working power for the heating element 152. The atomization channel 114 is provided with a liquid inlet hole 124 for connecting the atomization assembly 15 and the second liquid storage cavity 122. When the user inhales, the atomization substrate in the liquid tank 113 can enter the liquid storage cavity through the liquid supply hole 123, then pass through the liquid inlet hole 124 to the atomization channel 114, and then be heated by the heating element 152 of the atomization assembly 15 to form aerosol, and then reach the position of the suction nozzle 117 along the atomization channel 114 for the user to inhale.

[0050] Referring to FIG. 5 and FIG. 6, FIG. 5 is a cross-sectional view of the activation member 13 of the atomization device in the embodiment of FIG. 1 in the second cooperation position, and FIG. 6 is a cross-sectional view of the activation member 13 of the atomization device in the embodiment of FIG. 1 in the first cooperation position.

[0051] The activation member 13 is at least partially arranged in the second liquid storage cavity 122, and the activation member 13 has a first cooperation position and a second cooperation position, and the activation member 13 can reciprocate between the first cooperation position and the second cooperation position. When the activation member 13 is in the first cooperation position, the activation member 13 blocks the liquid inlet hole 124, and the first liquid storage cavity 121 and the second liquid storage cavity 122 are in a connected state, i.e., an isolated state of the atomization assembly 15 and the second liquid storage cavity 122; when the activation member 13 is in the second cooperation position, the activation member 13 blocks the liquid supply hole 123, and the second liquid storage cavity 122 and the atomization assembly 15 are in a connected state.

[0052] In the isolated state of the atomization assembly 15 and the second liquid storage cavity 122, the atomization substrate in the first liquid storage cavity 121 of the liquid tank 113 can enter the second liquid storage cavity 122 through the liquid supply hole 123, and the atomization substrate in the second liquid storage cavity 122 cannot enter the atomization channel 114 because the liquid inlet hole 124 is blocked by the activation member 13 at this time. When the second liquid storage cavity 122 is filled with the atomization substrate, the first liquid storage cavity 121 stops delivering the atomization substrate to the second liquid storage cavity 122, and the liquid volume of the first liquid storage cavity 121 in the liquid tank 113 is the capacity of the second liquid storage cavity 122; in the connected state of the atomization assembly 15 and the second liquid storage cavity 122, the atomization substrate in the second liquid storage cavity 122 can enter the atomization channel 114 to be consumed, and the first liquid storage cavity 121 cannot deliver the atomization substrate to the second liquid storage cavity 122 because the liquid supply hole 123 is blocked by the activation member 13 at this time. Therefore, the consumable amount of the atomization substrate after each activation is the capacity of the second liquid storage cavity 122, i.e., the liquid volume of the first liquid storage cavity 121 in the liquid tank 113.

[0053] With the above scheme, the atomization device 10 can make the atomization assembly 15 and the second liquid storage cavity 122 have an isolated state and a connected state by configuring the activation piece 13 to repeatedly move between the first matching position and the second matching position. In the isolated state of the atomization assembly 15 and the second liquid storage cavity 122, the activation piece 13 blocks the liquid inlet hole 124, which can improve the leakage-proof performance of the atomization assembly 15 and avoid long-time contact between the atomized substrate and the atomization assembly 15, thereby ensuring the quality and taste of the atomized substrate. In the connected state of the atomization assembly 15 and the second liquid storage cavity 122, the activation piece 13 blocks the liquid supply hole 123, which can improve the leakage-proof performance of the liquid tank 113 and control the amount of liquid in the liquid tank 113, thereby controlling the amount of atomized substrate consumed each time and the amount of smoking by the user, and avoiding excessive smoking by the user.

[0054] Referring to FIGS. 7 and 8, FIG. 7 is a schematic diagram of the connection relationship between the activation piece 13 and the atomization support in the embodiment of FIG. 1, and FIG. 8 is a schematic diagram of the structure of the activation piece 13 in the embodiment of FIG. 1. The activation piece 13 includes a first sealing portion 131, a second sealing portion 132, and an operation portion 133. The first sealing portion 131 is arranged in the second liquid storage cavity 122 and is used to block the liquid supply hole 123. The second sealing portion 132 is arranged in the second liquid storage cavity 122 and is used to block the liquid inlet hole 124. The operation portion 133 is fixedly connected with the first sealing portion 131 and the second sealing portion 132. The operation portion 133 is at least partially exposed from the second liquid storage cavity 122, so that the user can apply an external force to the operation portion 133 and drive the first sealing portion 131 and the second sealing portion 132 to move, thereby making the activation piece 13 move between the first matching position and the second matching position, and further switching the isolated state and the connected state of the atomization assembly 15 and the second liquid storage cavity 122.

[0055] In an embodiment, as shown in FIG. 6, the axial direction of the liquid supply hole 123 is parallel to the length direction of the atomization device 10, and the liquid supply hole 123 is arranged at the top of the housing 111 to reduce the leakage of the atomized substrate. The axial direction of the liquid inlet hole 124 is perpendicular to the length direction of the atomization device 10, and the liquid inlet hole 124 is located below the liquid supply hole 123 to facilitate the atomized substrate to enter the atomization pipeline 114 from the second liquid storage cavity 122. The activation piece 13 moves along the length direction of the atomization device 10 between the first matching position and the second matching position. The distance from the first matching position to the liquid supply hole 123 is greater than the distance from the second matching position to the liquid supply hole 123.

[0056] Referring to FIG. 7, in an embodiment, the first sealing portion 131 comprises an embedded protrusion 1312, which is at least partially embedded in the liquid supply hole 123 to seal the liquid supply hole 123 when the activation member 13 is in the second matching position. In an embodiment, the first sealing portion 131 further comprises a sealing plate 1311, which has an area greater than that of the liquid supply hole 123, and can abut against and tightly fit the end surface of the liquid supply hole 123 to seal the liquid supply hole 123 when the activation member 13 is in the second matching position. In an embodiment, the first sealing portion 131 comprises both the embedded protrusion 1312 and the sealing plate 1311, and the embedded protrusion 1312 is embedded in the liquid supply hole 123, and the sealing plate 1311 can abut against the end surface of the liquid supply hole 123 when the activation member 13 is in the second matching position. In an embodiment, the first sealing portion 131 further comprises a slot (not shown in the figure), and at least part of the hole wall of the liquid supply hole 123 is embedded in the slot and tightly fits the inner wall of the slot when the activation member 13 is in the second matching position.

[0057] Continuing to refer to FIG. 7, the second sealing portion 132 is shaped to match the end surface of the liquid inlet hole 124 away from the atomization assembly 15, and the matching area of the second sealing portion 132 and the atomization duct 114 is greater than that of the liquid inlet hole 124. In an embodiment, the liquid inlet hole 124 penetrates through the inner and outer side walls of the third atomization section 1143 of the atomization duct 114, and the second sealing portion 132 tightly fits the outer side wall of the third atomization section 1143. The second sealing portion 132 can move along the length direction of the atomization device 10 with the operation portion 133, i.e., the second sealing portion 132 can slide and tightly fit the outer side wall of the third atomization section 1143. In an embodiment, the outer side wall of the third atomization section 1143 is a circular arc surface, and the fitting surface of the second sealing portion 132 and the outer side wall of the third atomization section 1143 is also a circular arc surface. In an embodiment, the outer side wall of the third atomization section 1143 is a flat surface, and the fitting surface of the second sealing portion 132 and the outer side wall of the third atomization section 1143 is also a flat surface.

[0058] In an embodiment, the part of the operation portion 133 outside the shell 111 can be used to drive the first sealing portion 131 and the second sealing portion 132 to move along the length direction of the atomization device 10, and the position relationship between the first sealing portion 131 and the liquid supply hole 123 and the position relationship between the second sealing portion 132 and the liquid inlet hole 124 can be simultaneously controlled by moving the operation portion 133, so as to switch the isolation state and the communication state of the atomization assembly 15 and the second liquid storage cavity 122. In the isolation state and the communication state of the atomization assembly 15 and the second liquid storage cavity 122, one of the liquid inlet hole 124 and the liquid supply hole 123 is opened, and the other is sealed, so as to effectively control the liquid amount in the liquid tank 113.

[0059] The activation member 13 can be a one-piece structure or a split structure. In an embodiment, the activation member 13 is a one-piece structure, which is simple in structure and easy to form and assemble. In an embodiment, the activation member 13 can be a split structure, so that the first sealing portion 131, the second sealing portion 132 and the operation portion 133 can be made of different materials. For example, the first sealing portion 131 and the second sealing portion 132 can be made of silicone or rubber, which has good compressibility, so as to seal the liquid supply hole 123 and the liquid inlet hole 124; and the operation portion 133 can be made of a material with relatively high hardness, so as to reduce the deformation of the operation portion 133 when an external force is applied to the first sealing portion 131 and the second sealing portion 132 through the operation portion 133, thereby facilitating the activation operation.

[0060] Referring to FIGS. 6-8, in some embodiments, the activation member 13 further comprises a reset member 134 for driving the activation member 13 to move from the second engagement position to the first engagement position. Under the action of an external force, the activation member 13 moves from the first engagement position to the second engagement position, so that the atomization device 10 is in an activated state, i.e., the communication state of the atomization assembly 15 and the second liquid storage cavity 122. After the external force is removed, the activation member 13 can move from the second engagement position to the first engagement position under the action of the reset member 134, so that the atomization assembly 15 and the second liquid storage cavity 122 in the atomization device 10 remain in an isolated state. The reset member 134 can be a spring, a spring sheet or the like. In the present embodiment, only the spring is taken as an example for description. In an embodiment, the inner wall of the liquid supply hole 123 is provided with a positioning groove 1231, the reset member 134 is sleeved on the outer periphery of the embedded protrusion 1312 of the first sealing portion 131, and the two ends of the reset member 134 abut against the positioning groove 1231 and the sealing plate 1311, respectively. The first sealing portion 131 can move close to the liquid supply hole 123 under the action of an external force to overcome the elastic force of the reset member 134, so that the reset member 134 is compressed, the embedded protrusion 1312 of the first sealing portion 131 is inserted into the liquid supply hole 123 and tightly abuts against the hole wall of the liquid supply hole 123, thereby achieving the plugging of the liquid supply hole 123. After the external force is removed, the reset member 134 releases the elastic force to drive the first sealing portion 131 to move away from the liquid supply hole 123 to open the liquid supply hole 123. During the movement of the first sealing portion 131, the second sealing portion 132 and the operation portion 133 move synchronously.

[0061] Referring to FIG. 2, in an embodiment, the atomization device 10 is provided with a first magnet 24, and the power supply device 20 is provided with a second magnet 21, the first magnet 24 and the second magnet 21 jointly constitute a magnetic attraction member for fixedly connecting the atomization device 10 and the power supply device 20, the first magnet 24 and the second magnet 21 attract each other, and the magnetic force when the first magnet 24 and the second magnet 21 attract each other is greater than the elastic force of the reset member 134 when the reset member 134 is compressed. When the power supply device 20 and the atomization device 10 are assembled together, the first magnet 24 and the second magnet 21 attract each other, the power supply device 20 holds the operating part 133 of the activation member 13 that leaks outside the second liquid storage cavity 122, and the activation member 13 moves from the first matching position to the second matching position to block the liquid supply hole 123 by the first sealing part 131 and open the liquid inlet hole 124 by the second sealing part 132, at this time the reset member 134 is compressed, and because the magnetic force between the first magnet 24 and the second magnet 21 is greater than the elastic force of the reset member 134, the atomization device 10 and the power supply device 20 can be fixedly connected, that is, the atomization assembly 15 and the second liquid storage cavity 122 can be kept in a communication state. When the user pulls out the power supply device 20, the operating part 133 loses the holding pressure of the power supply device 20, and with the release of the elastic force of the reset member 134, the activation member 13 moves from the second matching position to the first matching position to open the liquid supply hole 123 by the first sealing part 131 and block the liquid inlet hole 124 by the second sealing part 132, and the atomization device 10 can keep the atomization assembly 15 and the second liquid storage cavity 122 in an isolated state by the elastic force of the reset member 134.

[0062] Of course, the connection and assembly of the atomization device 10 and the power supply device 20 can also adopt other forms, such as buckle connection, bolt connection, etc., as long as the atomization device 10 and the power supply device 20 can be detachably assembled and fixedly connected.

[0063] In this application, the atomization device 10 and the power supply device 20 are pressed during assembly to switch the atomization assembly 15 and the second liquid storage cavity 122 in the atomization device 10 from an isolated state to a communication state, and the reset member 134 is arranged to switch the atomization assembly 15 and the second liquid storage cavity 122 in the atomization device 10 from a communication state to an isolated state after the atomization device 10 and the power supply device 20 are separated, which is simple to operate, improves the ease of use of the atomization device 10, and enhances the user experience. The linkage of the operating part 133 and the power supply device 20 automatically switches the atomization assembly 15 and the second liquid storage cavity 122 from an isolated state to a communication state, avoiding the user forgetting to open the liquid inlet hole 124 during smoking, which causes the atomization assembly 15 to be caked. The linkage of the operating part 133 and the reset member 134 automatically switches the atomization assembly 15 and the second liquid storage cavity 122 from a communication state to an isolated state, avoiding the user forgetting to block the liquid inlet hole 124 after smoking, which causes the atomization substrate to deteriorate by being in contact with the atomization assembly 15 for a long time.

[0064] Referring to FIG. 4 and FIG. 5, in some embodiments, the atomization support 112 is provided with a guide hole 1121, the operation part 133 is arranged in the guide hole 1121 and moves along the axial direction of the guide hole 1121, the axial direction of the guide hole 1121 is parallel to the length direction of the atomization device 10, and a sealing ring 135 is arranged between the hole wall of the guide hole 1121 and the operation part 133. The operation part 133 is in a cylindrical shape, and the outer wall of the operation part 133 is provided with a groove 1331, the sealing ring 135 is clamped in the groove 1331 and tightly abuts against the hole wall of the guide hole 1121, and the atomization substrate can be prevented from leaking from the guide hole 1121 by arranging the sealing ring 135. The guide hole 1121 plays a guiding role in the movement of the activation part 13, the operation part 133 passes through the guide hole 1121 and extends to the outside of the second liquid storage cavity 122, so that the operation part 133 can be in abutting connection with the power supply device 20, or the user can hold the operation part 133 to drive the first sealing part 131 and the second sealing part 132 to move.

[0065] Referring to FIG. 9, FIG. 9 is a schematic view of the connection relationship between the liquid tank and the shell in the embodiment of FIG. 1.

When the protruding structure 1112 presses the leakage prevention part 1132, the plurality of dynamic sealing parts 1133 are folded towards the inside of the liquid outlet 1131 and are pressed into the gap between the protruding structure 1112 and the mounting port 1111, and the leakage prevention part 1132 is wrapped on the outer side wall of the protruding structure 1112, so that the liquid tank 113 and the shell 111 are sealingly connected.

[0066] Referring to FIG. 5 and FIG. 10, FIG. 10 is a structural schematic diagram of the base in the embodiment of FIG. 1. In some embodiments, the atomization device 10 further comprises a base 14, which is inserted into the shell 111 and is clamped and fixed with the shell 111. The base 14 is provided with an air inlet pipe 142, which extends from the side of the base 14 close to the atomization pipe 114 towards the atomization pipe 114. One end of the air inlet pipe 142 is in communication with the atomization pipe 114, and the other end is in communication with the external air. When the user inhales through the suction nozzle 117, the external air can enter the atomization pipe 114 through the air inlet pipe 142, balance the air pressure in the atomization pipe 114, and enable the aerosol to smoothly pass through the atomization pipe 114 to the position of the suction nozzle 117 to meet the air supply demand.

[0067] In an embodiment, the side of the base 14 close to the atomization pipe 114 is provided with a liquid collection cavity 141, and the orthographic projection of the atomization pipe 114 on a first plane is located within the orthographic projection of the liquid collection cavity 141 on the first plane. The first plane is a reference plane perpendicular to the axial direction of the atomization pipe 114. The liquid collection cavity 141 can collect the leaked or condensed atomization substrate in the atomization pipe 114, thereby avoiding the leakage of the atomization substrate to the outside of the shell 111 and reducing the user experience. The liquid collection cavity 141 is provided with a liquid absorbing member 145 made of a porous medium material such as fiber cotton. The liquid absorbing member 145 can absorb the leaked or condensed atomization substrate, thereby improving the leakage prevention effect.

[0068] In combination with the embodiment in which the atomization device 10 is provided with the first magnet 24, the first magnet 24 can be arranged on the side of the base 14 away from the atomization pipe 114. The base 14 is provided with an electrode hole 144 through which the electrode of the atomization assembly 15 passes to facilitate the establishment of electrical connection between the electrode and the power supply device 20. After passing through the base 14, the electrode hole 144 needs to be sealed to avoid leakage of the atomization substrate from the gap between the electrode hole 144 and the electrode. The base 14 is further provided with a connection channel 143 through which the operation part 133 of the activation member 13 passes to facilitate the abutting connection with the power supply device 20. The connection channel 143 can also extend a certain distance from the base 14 towards the atomization pipe 114, i.e., the top of the connection channel 143 is higher than the bottom wall of the liquid collection cavity 141, thereby reducing the leakage of the atomization substrate.

[0069] Referring to FIG. 5, in an embodiment, the atomization support 112 is provided with a second sealing member 146 at an end away from the atomization duct 114, the second sealing member 146 being fixedly attached to the inner wall of the outer shell 111 to seal the gap between the atomization support 112 and the base 14 and the outer shell 111. The second sealing member 146 has a ring structure, a portion of the second sealing member 146 being wrapped around the outer sidewall of the atomization support 112 and another portion being wrapped around the outer sidewall of the base 14, the second sealing member 146 being tightly attached to the inner sidewall of the outer shell 111. In this way, leakage of the atomization substrate from the gap between the atomization support 112 and the outer shell 111 or from the gap between the base 14 and the outer shell 111 can be avoided.
