Description

Atomizers and atomizing devices Technical Field

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

[0002] An atomizing device is a device that heats and atomizes the atomizing matrix stored in the oil reservoir through an atomizing component, allowing the user to inhale the atomized matrix. To prevent leakage during manufacturing, transportation, and sales, some atomizing devices typically employ an oil-core separation design, meaning the atomizing core does not contact the atomizing matrix before use, thus reducing the risk of leakage. However, such atomizing devices have the following drawbacks: (1) The initial activation of the atomizing core requires a longer lubrication time, resulting in a poor user experience. (2) The oil-core separation design usually uses silicone or other sealing materials to achieve a seal before the atomizing core is activated. Because silicone or other sealing materials are relatively soft, the atomizing matrix can easily seep into the atomizing core through the gap between the sealing material and the atomizing component, posing a risk of seal failure. Summary of the Invention

[0005] In some embodiments, the atomizing assembly includes an atomizing sleeve and an atomizing core disposed within the atomizing sleeve, the liquid inlet being disposed on the atomizing sleeve and facing the atomizing core, the atomizing core being fitted against the inner wall of the atomizing sleeve, and the sealing member wrapping around the outer periphery of the atomizing sleeve.

[0007] In some embodiments, the seal further includes a first end face that contacts the second inner surface; a drainage portion is formed at the connection between the first end face and the second inner surface, the drainage portion including an arc surface and / or a slope facing the atomizing sleeve.

[0008] In some embodiments, the second inner surface includes at least one first inclined portion, the first inclined portion including an arc surface and / or a slope disposed toward the atomizing sleeve; and / or, the sleeve has a second inclined portion on the outer periphery of the end where the first flange is located, the second inclined portion including an arc surface and / or a slope disposed toward the seal.

[0009] In some embodiments, the inner wall of the sleeve is further provided with at least one second flange, the second flange and the first flange are located at the same end of the sleeve, the second flange is located on the side of the sleeve facing the atomizing sleeve, and the second flange abuts against the atomizing sleeve.

[0010] In some embodiments, the inner wall of the sleeve is further provided with at least one third flange, the third flange being located above the second flange, and the liquid inlet being located between the second flange and the third flange.

[0011] In some embodiments, the housing includes a main body and a suction nozzle inner tube connected to each other; the sleeve is sealed around the outer periphery of the suction nozzle inner tube, and the suction nozzle inner tube defines an air outlet channel; the main body is disposed around the outer periphery of the seal; the main body, the seal, the sleeve, and the suction nozzle inner tube together define the liquid storage chamber; the operating part includes a pull rod, the sleeve is connected around the outer periphery of the pull rod, the pull rod passes through the air outlet channel and is partially located outside the housing, and the pull rod can be physically separated from the sleeve and removed under the action of external force.

Therefore, the various orders in the specification and drawings are only for the clear description of a particular embodiment and do not imply a necessary order, unless otherwise stated that a particular order must be followed.

[0036] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the objects being described and have no sequential or technical meaning. Unless otherwise specified, the terms "connection" and "linkage" used in this application include both direct and indirect connections (linkages).

[0037] Referring to Figures 1 to 4, in some embodiments, an atomizing device is provided, comprising an atomizer 1, a power supply unit 2, and a control unit 3. The power supply unit 2 provides power to the atomizer 1 and the control unit 3. The atomizer 1 contains an atomizing matrix, which can be liquid or solid. Liquid atomizing matrices include e-liquid, medicinal liquids, etc. When powered on, the atomizer 1 heats the atomizing matrix to generate an aerosol for the user to inhale. The control unit 3 is connected to both the power supply unit 2 and the atomizer 1. The control unit 3 receives power from the power supply unit 2 and can also control the power supply to the atomizer 1, thereby controlling the atomization switch of the atomizer 1, i.e., controlling the atomizer 1 to be in a heating state and a heating state.

[0038] Referring to Figures 1 to 4, in some embodiments, the power supply unit 2 includes a first housing 21 and a battery 22. The first housing 21 defines a first receiving cavity 210, in which the battery 22 is housed. The atomizer 1 and the control unit 3 are connected as a single unit. The atomizer 1 and the first housing 21 are detachably connected. During assembly, the atomizer 1 is inserted into the first receiving cavity 210 from the open end of the first housing 21, connecting the atomizer 1 to the battery 22. By connecting the atomizer 1 and the control unit 3 as a single unit, no additional positioning structure is required for the control unit 3, saving parts and facilitating assembly. Alternatively, in other embodiments, the connection between the atomizer 1 and the first housing 21 may be non-detachable. The control unit 3 may be mounted at the bottom of the atomizer 1. When the atomizer 1 is inserted into the first receiving cavity 210 from the open end of the first housing 21, the control unit 3 is connected to the battery 22. In some embodiments, the control unit 3 may include components such as a circuit board.

[0039] As shown in Figures 4 and 5, in some embodiments, the atomizer 1 includes an atomizing component 11, a seal 12, an isolation component 13, and a second housing 15.

[0040] When energized, the atomizing component 11 heats the atomizing matrix to generate an aerosol for the user to inhale. The atomizing component 11 has a first end 11A, a second end 11B, and a liquid inlet 110 located between the first end 11A and the second end 11B. The liquid inlet 110 is used to input the atomizing matrix into the atomizing component 11. Specifically, the atomizing component 11 includes a hollow atomizing sleeve 111 that extends through both ends, and an atomizing core disposed inside the atomizing sleeve 111. That is, the atomizing sleeve 111 provides an atomizing space for generating the aerosol, and the atomizing core is disposed within this atomizing space. Simultaneously, the atomizing sleeve 111 also serves as a mounting support for the atomizing core, providing a foundation for its installation.

[0041] A liquid inlet 110 is located on the atomizing sleeve 111 and faces the atomizing core. The atomizing core is fitted against the inner wall of the atomizing sleeve 111, and a sealing member 12 wraps around the outer periphery of the atomizing sleeve 111. The atomizing core includes a liquid guide 112 and a heating element 113 attached to the liquid guide 112. The liquid guide 112 is fitted against the inner wall of the atomizing sleeve 111. In some embodiments, the liquid guide 112 can be an annular liquid guide 112, and the heating element 113 is attached to the inner circumferential surface of the annular liquid guide 112. The heating element 113 can be cylindrical, mesh-like, or a combination of cylindrical and mesh-like. The cylindrical heating element 113 can be vertically arranged on the liquid guide 112 as shown in Figure 11 (that is, the two open ends of the cylindrical heating element 113 correspond to the two open ends of the annular liquid guide 112), or it can be horizontally wound around a horizontally arranged liquid guide. In other embodiments, the heating element 113 can also be a planar heating pattern formed on the liquid guiding component by processes such as printing. The atomizing sleeve 111 has a liquid inlet hole 110 on its side wall. The liquid guiding component 112 fits against the inner wall of the atomizing sleeve 111 and covers the liquid inlet hole 110. The atomizing matrix can enter the interior of the atomizing sleeve 111 through the liquid inlet hole 110 and contact the heating element 113 via the liquid guiding component 112. When energized, the heating element 113 generates heat and transfers it to the atomizing matrix, which is then heated and atomized to produce an aerosol. The first end 11A and the second end 11B of the atomizing sleeve 111 serve as the first end 11A and the second end 11B of the atomizing assembly 11.

[0042] The isolation assembly 13 includes a sleeve 131 and an operating part 132. The atomizing core 11, the seal 12, and the sleeve 131 are disposed within the second housing 15. The operating part 132 is at least partially exposed outside the second housing 15; that is, the operating part 132 may be partially or completely exposed outside the second housing 15. The second housing 15, the seal 12, and the sleeve 131 together define a liquid reservoir 14. The liquid reservoir 14 is used to store the atomizing matrix. The isolation assembly 13 is used to control the communication between the atomizing assembly 11 and the liquid reservoir 14, thereby controlling the transition of the atomizing assembly 11 from an inactive state to an active state.

[0043] The seal 12 can be an elastic element made of materials such as silicone or rubber. The seal 12 may also include an elastic element and a reinforcing member embedded in the elastic element. The reinforcing member can be made of metal, such as a steel sheet. The combination of the elastic element and the reinforcing member can increase the overall rigidity of the seal 12 and prevent the sealing element 12 from deforming during the upward movement of the isolation component 13, which could lead to leakage of the atomized matrix.

[0044] As shown in Figure 5, in some embodiments, the atomizer further includes a receiving seat 16 defining a second receiving cavity. After the atomizing sleeve 111 is fitted onto the outer periphery of the liquid guide 112 and the sealing member 12 is fitted onto the outer periphery of the atomizing sleeve 111, the entire assembly formed by the atomizing component 11, the sealing member 12, and the atomizing sleeve 111 can be received within the second receiving cavity. A control component can be mounted at the bottom of the receiving seat 16.

[0045] In some embodiments, both the sleeve 131 and the operating part 132 can be elastic components, such as those made of silicone or rubber, enabling them to provide a sealing function. One end of the sleeve 131 has a first flange 133. When the sleeve 131 contacts other components, it can maintain a tight fit with them through elastic force, thereby achieving a sealing effect. Because the sleeve 131 can be an elastic component, the end of an elastic component may lack sufficient rigidity, potentially leading to sealing failure at the end of the sleeve 131. Therefore, the first flange 133 is provided to enhance the sealing performance at the end of the sleeve 131.

[0046] Referring to Figures 4 and 5, the first end 11A of the atomizing component 11 (atomizing sleeve 111) is its upper end, and the second end 11B of the atomizing component 11 (atomizing sleeve 111) is its lower end. The sealing element 12 and the sleeve 131 are respectively fitted around the outer periphery of the atomizing component 11. Specifically, the sealing element 12 is located between the liquid inlet 110 and the second end 11B; the sleeve 131 is located above the sealing element 12, that is, the sleeve 131 is closer to the first end 11A of the atomizing component 11 (atomizing sleeve 111) than the sealing element 12.

[0047] The sealing element 12 is fitted onto the outer periphery of the second end 11B, and a buffer gap 40 is defined between it and the atomizing component 11. This buffer gap 40 is used to provide buffer space for the atomizing substrate, thereby shortening the wicking time. The wicking time refers to the preset time required for the atomizing component 11 to penetrate into the atomizing substrate during its first contact with the atomizing substrate.

[0048] As shown in Figure 6, in the initial state (i.e., when the isolation component 13 has not been moved, for example, when the atomizer 1 is manufactured), the sleeve 131 is fitted around the outer periphery of the first end 11A and covers the liquid inlet 110. One end of the sleeve 131 with a first flange 133 extends into the buffer gap 40, and the first flange 133 abuts against the inner wall of the seal 12.

[0049] The isolating component 13 is movable away from the seal 12. That is, the isolating component 13 is movable in a direction away from the seal 12. During the movement of the isolating component 13, the atomizer 1 includes at least two states: a first state and a second state.

[0050] As shown in Figure 7, in the first state, the first flange 133 releases its contact with the inner wall of the seal 12, and the sleeve 131 covers the liquid inlet hole 110. As shown in Figure 8, in the second state, the sleeve 131 releases its cover over the liquid inlet hole 110, allowing the liquid storage chamber 14 to connect with the liquid inlet hole 110.

[0051] Specifically, please refer to Figures 6 to 8 together. The initial state, the first state, and the second state can be arranged in chronological order:

[0052] As shown in Figure 6, in the initial state, the first flange 133 on the sleeve 131 abuts against the seal 12, and the sleeve 131 covers the liquid inlet 110, preventing the liquid storage chamber 14 from communicating with the liquid inlet 110. Because the liquid storage chamber 14 is not connected to the liquid inlet 110, the atomizing core cannot contact the atomizing matrix in the liquid storage chamber 14. Therefore, the initial state is also considered the unactivated state of the atomizing core of the atomizing assembly 11. At this time, the first flange 133 of the sleeve 131 is located in the buffer gap 40. The abutment between the first flange 133 and the seal 12 improves the sealing performance of the end of the sleeve 131, preventing the seal between the liquid storage chamber 14 and the liquid inlet 110 from failing before the atomizing core is activated due to insufficient rigidity at the end of the sleeve 131.

[0053] As shown in Figure 7, in the first state, the first flange 133 separates from the seal 12, connecting the buffer space with the liquid storage chamber 14. That is, the atomizing matrix in the liquid storage chamber 14 can begin to enter the buffer space. The sleeve 131 still covers the liquid inlet 110, preventing communication between the liquid storage chamber 14 and the liquid inlet 110. The buffer space is also not connected to the liquid inlet 110. Because the liquid storage chamber 14 and the liquid inlet 110 are still not connected, the atomizing component 11 cannot contact the atomizing matrix in the liquid storage chamber 14, so the second state is also considered an inactive state for the atomizing component 11. The arrows in the figure indicate the approximate flow direction of the atomizing matrix.

[0054] As shown in Figure 8, in the second state, the first flange 133 separates from the seal 12, and the sleeve 131 separates from the inlet port 110, connecting the buffer space, the storage chamber 14, and the inlet port 110. At this time, the atomizing matrix buffered in the buffer space and the atomizing matrix in the storage chamber 14 both flow into the inlet port 110. Because a certain amount of atomizing matrix is ​​pre-buried in the buffer space, when the sleeve 131 separates from the inlet port 110, the atomizing matrix can quickly enter the atomizing sleeve 111 of the atomizing assembly 11, thereby shortening the wicking time. The arrows in the figure indicate the approximate flow direction of the atomizing matrix.

[0055] Referring to Figures 4 and 5, in some embodiments, the atomizer 1 further includes a second housing 15, which includes a main body 151 and a mouthpiece inner tube 152 connected to each other. The main body 151 serves as the outer housing, enclosing the atomizing assembly 11, the seal 12, and the sleeve 131. The mouthpiece inner tube 152 is disposed inside the main body 151 and connected to the sleeve 131. The mouthpiece inner tube 152 defines an air outlet channel 153 (see Figures 12 and 13). The end of the air outlet channel 153 is also the air outlet end of the atomizing device. The aerosol generated at the atomizing assembly 11 is output from the air outlet end to the outside of the device through the air outlet channel 153 for the user to inhale.

[0056] The main body 151 is fitted around the outer periphery of the seal 12. The main body 151, the seal 12, the sleeve 131, and the inner tube 152 of the suction nozzle together define the liquid storage chamber 14. The sleeve 131 is fitted around the outer periphery of the operating part 132, which is detachably disposed within the air outlet channel 153.

[0057] As shown in Figures 9 and 10, referring to the top and bottom positions shown, in some embodiments, the operating part 132 includes a pull rod. A sleeve 131 is connected to the outer periphery of the pull rod. The pull rod passes through the air outlet channel 153 and is partially located outside the second housing 15. The pull rod can be physically separated from the sleeve 131 and removed under external force. Specifically, the sleeve 131 and the outer periphery of the pull rod are connected by a connecting part 41. A groove 42 is also formed between the outer periphery of the sleeve 131 and the inner tube 152 of the suction nozzle. The groove 42 extends downward from the end of the sleeve 131 away from the seal 12 (i.e., the upper end of the sleeve 131) to the upper surface of the connecting part 41. The end of the inner tube 152 of the suction nozzle away from the main body 151 is embedded in the groove 42. As the lever moves upward relative to the atomizing assembly 11, the lower end of the nozzle inner tube 152 (that is, the end of the nozzle inner tube 152 away from the main body 151) gradually approaches the connecting part 41 and eventually comes into contact with the connecting part 41. The connecting part 41 has a small thickness, so that it can break under the force of the lower end of the nozzle inner tube 152, causing the sleeve 131 and the lever to separate.

[0058] In other embodiments, the operating part 132 may also include a push rod disposed below the sleeve 131 (e.g., at the bottom of the second housing 15) or a push block exposed on the side of the second housing 15, as long as the operating part 132 is connected to the sleeve 131 and can drive the sleeve 131 to move.

[0059] Please refer to Figures 4, 6 through 8, and 11 through 13. Figures 4 and 6 show the initial state of the atomizer, Figure 7 shows the first state of the atomizer, Figure 8 shows the second state of the atomizer, Figure 11 shows the third state of the atomizer, Figure 12 shows the fourth state of the atomizer, and Figure 13 shows the fifth state of the atomizer. The initial state to the fifth state can be arranged in chronological order; that is, the six position states of the operating unit 132 during its upward movement are illustrated from the initial state to the fifth state.

[0060] Figures 4 and 6 show the initial state, i.e., the atomizing component 11 is not activated. At this time, the liquid storage chamber 14 and the liquid inlet 110 are not connected. If the operating part 132 is pulled upwards, the sleeve 131 and the operating part 132 move upwards together until the third state shown in Figure 11 is reached. In this state, the liquid inlet 110 and the liquid storage chamber 14 are connected, and the atomizing component 11 is activated. Furthermore, the lower end of the mouthpiece inner tube 152, which is fitted into the groove 42, just abuts against the connecting part 41. If the operating part 132 is pulled upwards again, the connecting part 41 breaks due to the downward force provided by the mouthpiece inner tube 152, as shown in Figure 12. In the fourth state, the sleeve 131 and the operating part 132 are separated. As shown in Figure 13, if the operating part 132 is pulled upwards again, the atomizer is in the fifth state. The operating part 132 is separated from the air outlet channel 153, while the sleeve 131 continues to be fitted onto the outer circumferential surface of the mouthpiece inner tube 152.

[0061] Therefore, when the atomizing component 11 is not activated, such as during transportation, the operating part 132 can be used to block the air outlet channel 153, preventing external contaminants from entering the air outlet channel 153, thus acting as a dust plug. When it is necessary to activate the atomizer 1, the user only needs to pull the operating part 132 upwards until the atomizing component 11 enters the activated state, and then remove the operating part 132. This process of activating the atomizing component 11 is simple and reliable.

[0062] As shown in Figures 9 and 10, in some embodiments, the seal 12 includes a first inner surface 121 and a second inner surface 122 disposed toward the atomizing sleeve 111. The first inner surface 121 contacts the outer periphery of the atomizing sleeve 111 to fix the relative position between the seal 12 and the atomizing sleeve 111. The second inner surface 122 defines a buffer gap 40 between itself and the atomizing sleeve 111. The seal 12 is annular, and the cross-sectional dimension of the cavity enclosed by the second inner surface 122 is larger than the cross-sectional dimension of the cavity enclosed by the first inner surface 121. In an initial state, a first flange 133 abuts against the second inner surface 122; in a first state, the first flange 133 is separated from the second inner surface 122.

[0063] As shown in Figures 6 to 10, in some embodiments, the seal 12 further includes a first end face 123 and a second end face 124. Referring to the orientation in Figures 9 and 10, the first end face 123 is the upper end face of the seal 12, and the second end face 124 is the lower end face of the seal 12. The first end face 123 faces the liquid storage cavity 14 and is in contact with the first inner surface 121. The second end face 124 faces away from the liquid storage cavity 14. A drainage portion 51 is formed at the junction of the first end face 123 and the second inner surface 122. This drainage portion 51 includes an arc surface and / or an inclined surface facing the atomizing sleeve 111. That is, the drainage portion 51 may include one of an arc surface and an inclined surface, or a combination of both. Both the arc surface and the inclined surface are facing the atomizing sleeve 111. That is, the inclined surface is inclined towards the atomizing sleeve 111. For example, in the embodiments shown in Figures 6 to 8, a slope is provided at the connection between the first end face 123 and the second inner surface 122. This slope serves as a flow guide 51. When the liquid storage chamber 14 is connected to the buffer gap 40, the slope guides the atomizing matrix to flow into the buffer gap 40, thereby accelerating the flow rate of the atomizing matrix between the liquid storage chamber 14, the buffer gap 40, and the liquid inlet 110, which is beneficial for achieving a rapid core lubrication effect. In some other embodiments, an arc surface can also play a similar role to the slope, which will not be described in detail here.

[0064] As shown in Figures 6 to 10, in some embodiments, the second inner surface 122 includes at least one first inclined portion 52, which also includes an arc surface and / or a slope facing the atomizing sleeve 111. That is, the first inclined portion 52 may include one of an arc surface and a slope, or a combination of both. The number of first inclined portions 52 may be one or more, and this application does not limit this.

[0065] As shown in Figures 6 to 10, in some embodiments, the sleeve 131 has a second inclined portion 53 on the outer periphery of the end where the first flange 133 is located. This second inclined portion 53 also includes an arcuate surface and / or a slope facing the seal 12. That is, the second inclined portion 53 may include one of an arcuate surface and a slope, or a combination of both. Referring to the orientation in Figure 10, the second inclined portion 53 is located below the first flange 133. As shown in Figure 6, in the initial state, the second inclined portion 53 can contact the second inner surface 122 of the seal 12. When the second inner surface 122 of the seal 12 is provided with a first inclined portion 52, and the sleeve 131 is also provided with a second inclined portion 53 at the end where the first flange 133 is located, the shapes of the first inclined portion 52 and the second inclined portion 53 can be matched. For example, both include a slope, or both include an arc surface. The shapes of the two slopes or the two arc surfaces are consistent and compatible. Thus, the end of the sleeve 131 can be pressed against the first inclined portion 52 of the seal 12 through the second inclined portion 53, and the two can maintain a good sealing fit effect, further enhancing the sealing effect between the liquid storage cavity 14 and the liquid inlet 110 in the initial state. As shown in Figure 7, in the first state, the first inclined portion 52 guides the atomizing matrix to flow quickly from the liquid storage cavity 14 to fill the buffer gap 40 along the flow direction of the atomizing matrix. Furthermore, as shown in Figure 7, when the first flange 133 just separates from the seal 12, the atomizing matrix can already pass through the gap between the first flange 133 and the seal 12 and enter the buffer gap 40. The design of the first inclined part 52 can increase the size of the gap between the first flange 133 and the seal 12 when the first flange 133 just separates from the seal 12, thereby making more space available for the atomizing matrix to flow from the liquid storage chamber 14 to the buffer gap 40. This helps to accelerate the flow speed of the atomizing matrix between the liquid storage chamber 14, the buffer gap 40 and the liquid inlet 110, which is beneficial to achieving the effect of rapid lubrication of the core.

[0066] As shown in Figures 6 to 10, in some embodiments, the sleeve 131 is further provided with a third inclined portion 54 facing the atomizing sleeve 111 at the end where the first flange 133 is located. The third inclined portion 54 also includes an arc surface and / or a slope facing the atomizing sleeve 111. That is, the third inclined portion 54 may include one of an arc surface and a slope, or a combination of both. The second inclined portion 53 and the third inclined portion 54 are symmetrically arranged on opposite sides of the inner wall of the sleeve 131. Specifically, the second inclined portion 53 is located on the side of the sleeve 131 facing the seal 12 (that is, the side facing away from the atomizing sleeve 111), and the third inclined portion 54 is located on the side of the sleeve 131 facing the atomizing sleeve 111 (that is, the side facing away from the seal 12).

[0067] The first inclined portion 52, the second inclined portion 53, and the third inclined portion 54 can be used to guide the installation of the isolation assembly 13. Furthermore, similar to the function of the first flange 133, the first inclined portion 52, the second inclined portion 53, and the third inclined portion 54 can also improve the sealing effect between the sleeve 131 and the seal 12.

[0068] As shown in Figures 6 to 10, in some embodiments, the inner wall of the sleeve 131 is further provided with at least one second flange 134. That is, the inner wall of the sleeve 131 can be provided with one second flange 134, or multiple flanges (two or more) of the second flange 134. The second flange 134 and the first flange 133 are located at the same end of the sleeve 131 (i.e., the lower end in the figure). The second flange 134 is located on the side of the sleeve 131 facing the atomizing sleeve 111, and the first flange 133 is located on the side of the sleeve 131 facing away from the atomizing sleeve 111. Both the first flange 133 and the second flange 134 can be structures that protrude laterally. The lateral direction can refer to a direction perpendicular to the axial direction, which can refer to the up-down direction shown in Figures 10 to 13. This axial direction can also refer to the length direction of the atomizing device, and this axial direction can also refer to the air outlet direction of the atomizing device.

[0069] At least in the initial and first states, the second flange 134 abuts against the atomizing sleeve 111. That is, as shown in Figures 6 and 7, in the initial and first states, on one side of the atomizing sleeve 111, the second flange 134 abuts against the atomizing sleeve 111, preventing the liquid inlet 110 from communicating with the buffer gap 40 and the liquid inlet 110 from communicating with the liquid storage chamber 14, thereby maintaining the inactive state of the atomizing assembly 11. As shown in Figure 6, in the initial state, the first flange 133 abuts against the second inner surface 122 of the seal 12, and the second flange 134 abuts against the atomizing sleeve 111. Through the abutting force on both sides, the sealing performance of the lower end of the sleeve 131 is significantly enhanced. With the first flange 133 and the second flange 134 provided simultaneously, the first flange 133 and the second flange 134 together improve the sealing performance of the lower end of the sleeve 131, and avoid the sealing failure between the liquid storage chamber 14 and the liquid inlet 110 before the atomizing core is activated due to insufficient rigidity of the lower end of the sleeve 131.

[0070] As shown in Figure 10, in some embodiments, the inner wall of the sleeve 131 is further provided with at least one third flange 135. That is, the inner wall of the sleeve 131 can be provided with one third flange 135, or multiple flanges (two or more) of the third flange 135. Referring to the orientation indication in Figure 10, the third flange 135 is located above the second flange 134, and the liquid inlet 110 is located between the second flange 134 and the third flange 135. Thus, in the initial state, it can be ensured that both the upper and lower sides of the liquid inlet 110 have good sealing performance, effectively preventing sealing failure before the atomizing core is activated.
