Description

Technical Field

[0001] The utility model relates to the technical field of atomization, and in particular to an atomizer and an atomization device. Background Art

[0002] An atomization device is a device that heats and atomizes an atomization matrix stored in an oil storage member through an atomization component so that a user can inhale the atomized matrix. In order to prevent oil leakage during the ex-factory transportation and sales of some related atomization devices, an oil core separation design is usually adopted, that is, the atomization core does not contact the atomization matrix before use, thereby reducing the risk of oil leakage. However, the defects of such atomization devices include: (1) When the atomization core is activated for the first time, the wicking time is relatively long and the user experience is poor. (2) The oil core separation design usually uses seals such as silica gel to achieve the seal before the atomization core is activated. Since the texture of seals such as silica gel is relatively soft, the atomization matrix easily penetrates into the atomization core through the gap between the seal and the atomization component, and there is a risk of seal failure. Summary of the Utility Model

[0003] The technical problem to be solved by this application is to provide an improved atomizer and atomization device, which can shorten the wicking time and reduce the risk of seal failure before the atomization core is activated.

[0005] The atomization component has a first end, a second end and a liquid inlet hole located between the first end and the second end;

[0006] The isolation component includes a sleeve and an operation part connected to each other. The atomization component, the seal and the sleeve are arranged in the housing, and the operation part is at least partially exposed outside the housing. The housing, the seal and the sleeve together define a liquid storage cavity, and a first flange is provided on the outer periphery of one end of the sleeve;

[0007] The seal is sleeved on the outer periphery of the second end and defines a buffer gap between the seal and the atomization component;

[0008] The sleeve is sleeved on the outer periphery of the first end and covers the liquid inlet hole. One end of the sleeve provided with the first flange extends into the buffer gap, and the first flange abuts against the inner wall of the seal;

[0009] The isolation component can move away from the seal. During the movement of the isolation component, the atomizer includes at least two states:

[0010] In the first state, the first flange releases the abutment against the inner wall of the seal, and the sleeve covers the liquid inlet hole;

[0011] In the second state, the sleeve releases the covering of the liquid inlet hole, so that the liquid storage cavity communicates with the liquid inlet hole.

[0012] In some embodiments, the atomization assembly includes an atomization sleeve and an atomization core disposed in the atomization sleeve. The liquid inlet hole is disposed on the atomization sleeve and faces the atomization core. The atomization core is attached to the inner wall of the atomization sleeve, and the seal wraps the outer periphery of the atomization sleeve.

[0013] In some embodiments, the seal includes a first inner surface and a second inner surface facing the atomization sleeve. The first inner surface contacts the outer periphery of the atomization sleeve, and a buffer gap is defined between the second inner surface and the atomization sleeve; the first flange abuts against the second inner surface; in the first state, the first flange releases the abutment with the second inner surface.

[0014] In some embodiments, the seal further includes a first end surface connected to the second inner surface; a drainage portion is formed at the connection of the first end surface and the second inner surface, and the drainage portion includes an arc surface and / or an inclined surface facing the atomization sleeve.

[0015] In some embodiments, the second inner surface includes at least one first inclined portion, and the first inclined portion includes an arc surface and / or an inclined surface facing the atomization sleeve;

[0016] And / or, the outer periphery of the end of the sleeve where the first flange is located is provided with a second inclined portion, and the second inclined portion includes an arc surface and / or an inclined surface facing the seal.

[0017] In some embodiments, at least one circle of second flanges is further provided on the inner wall of the sleeve. The second flanges and the first flanges are located at the same end of the sleeve. The second flanges are located on the side of the sleeve facing the atomization sleeve, and the second flanges abut against the atomization sleeve.

[0018] In some embodiments, at least one circle of third flanges is further provided on the inner wall of the sleeve. The third flanges are located above the second flanges, and the liquid inlet hole is located between the second flanges and the third flanges.

[0019] In some embodiments, the housing includes an adjoining main body portion and an inner nozzle tube; the sleeve is sealingly sleeved on the outer periphery of the inner nozzle tube, and the inner nozzle tube defines an air outlet channel; the main body portion is disposed on the outer periphery of the seal; the main body portion, the seal, the sleeve, and the inner nozzle tube together define the liquid storage cavity; the operation portion includes a pull rod, the sleeve is connected to the outer periphery of the pull rod, the pull rod passes through the air outlet channel, and part of the pull rod is located outside the housing, and the pull rod can be physically separated from the sleeve under the action of an external force and removed.

[0020] In some embodiments, the sleeve is connected to the outer periphery of the pull rod through a connecting portion; a groove is further formed between the outer peripheries of the sleeve and the inner nozzle tube, and the groove penetrates from one end of the sleeve away from the seal to the connecting portion; one end of the inner nozzle tube away from the main body portion is embedded in the groove; during the upward movement of the pull rod, the lower end portion of the inner nozzle tube can abut against the connecting portion, and the connecting portion can be broken under the action of the lower end portion of the inner nozzle tube, so that the sleeve and the pull rod are separated.

[0021] The present application further provides an atomizing device, which includes a power supply unit, a control unit, and the atomizer according to any one of the above, the power supply unit provides power for the atomizer, and the control unit is used to control the atomizer.

[0022] According to the atomizing device of the above embodiment, since a certain amount of atomizing matrix is pre-cached in the buffer space, when the sleeve is separated from the liquid inlet hole, the atomizing matrix can quickly enter the inside of the atomizing component, thereby shortening the wicking time; since a first flange is provided at one end of the sleeve to abut against the seal, in the state where the atomizing core is not activated, the abutment between the first flange and the seal improves the sealing performance of the end of the sleeve, and avoids the sealing failure between the liquid storage cavity and the liquid inlet hole before the atomizing core is activated due to insufficient rigidity at the end of the sleeve.

[0043] In addition, the features, operations, or characteristics described in the specification can be combined in any appropriate manner to form various implementation modes.

And the "connection" and "coupling" mentioned in the present application, unless otherwise specified, both include direct and indirect connection (coupling).

[0045] Please refer to Figures 1 to 4 , in some embodiments, an atomizing device is provided. The atomizing device includes an atomizer 1, a power supply unit 2, and a control unit 3. The power supply unit 2 is used to provide power for the atomizer 1 and the control unit 3. The atomizer 1 is used to accommodate an atomizing matrix, and the atomizing matrix can be a liquid or solid atomizing matrix. The liquid atomizing matrix includes e-liquid, medicinal liquid, etc. The atomizer 1 can heat the atomizing matrix when powered on to generate an aerosol for the user to inhale. The control unit 3 is respectively connected to the power supply unit 2 and the atomizer 1. On the one hand, the control unit 3 accesses power from the power supply unit 2, and on the other hand, it can be used to control the power on and off of the atomizer 1, thereby controlling the atomizing switch of the atomizer 1, that is, controlling the atomizer 1 to turn on the heating state and stop the heating state.

[0046] Please refer 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, and the battery 22 is received in the first receiving cavity 210. The atomizer 1 and the control unit 3 are connected as a whole. 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 so that the atomizer 1 is connected to the battery 22. Connecting the atomizer 1 and the control unit 3 as a whole eliminates the need to design an additional positioning structure for the control unit 3, saving components and facilitating assembly. Alternatively, in other embodiments, the connection between the atomizer 1 and the first housing 21 can also be non-detachable. The control unit 3 can be installed 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. The control unit 3 may include circuit boards and other components in some embodiments.

[0047] As Figure 4 and Figure 5 shown, in some embodiments, the atomizer 1 includes an atomization assembly 11, a seal 12, an isolation assembly 13, and a second housing 15.

[0048] The atomization assembly 11 can heat the atomization matrix to generate an aerosol for the user to inhale when powered on. The atomization assembly 11 has a first end 11a, a second end 11b, and a liquid inlet hole 110 located between the first end 11a and the second end 11b. The liquid inlet hole 110 is used to input the atomization matrix into the atomization assembly 11. Specifically, the atomization assembly 11 includes an atomization sleeve 111 that is hollow and has through holes at both ends, and an atomization core disposed inside the atomization sleeve 111. That is, the atomization sleeve 111 can provide an atomization space for generating the aerosol, and the atomization core is disposed in this atomization space. At the same time, the atomization sleeve 111 also serves as a mounting carrier for the atomization core, providing a basis for the installation of the atomization core.

[0049] The liquid inlet hole 110 is provided on the atomization sleeve 111 and is aligned with the atomization core. The atomization core is in contact with the inner wall of the atomization sleeve 111, and the seal 12 wraps around the outer periphery of the atomization sleeve 111. The atomization core includes a liquid guiding member 112 and a heating element 113 attached to the liquid guiding member 112. The liquid guiding member 112 is in contact with the inner wall of the atomization sleeve 111. The liquid guiding member 112 can be an annular liquid guiding member 112 in some embodiments, and the heating element 113 is attached to the inner peripheral surface of the annular liquid guiding member 112. The heating element 113 can be in a cylindrical shape, a mesh shape, or a combination of a cylindrical shape and a mesh shape as a whole. The cylindrical heating element 113 can be as Figure 11vertically disposed on the liquid guide member 112 (i.e., the two open ends of the cylindrical heating element 113 correspond to the two open ends of the annular liquid guide member 112), or can be horizontally wound around a horizontally disposed liquid guide member. In some other embodiments, the heating element 113 can also be a planar heating pattern formed on the liquid guide member by processes such as printing. The side wall of the atomization sleeve 111 is provided with a liquid inlet hole 110. The liquid guide member 112 is attached to the inner wall of the atomization sleeve 111 and covers the liquid inlet hole 110. The atomization matrix can enter the interior of the atomization sleeve 111 from the liquid inlet hole 110, contact the heating element 113 via the liquid guide member 112. The heating element 113 can generate heat in the energized state and transfer the heat to the atomization matrix, heating and atomizing the atomization matrix to generate an aerosol. The first end 11a and the second end 11b of the atomization sleeve 111 serve as the first end 11a and the second end 11b of the atomization assembly 11.

[0050] The isolation assembly 13 includes a sleeve 131 and an operation part 132 that are connected. The atomization core 11, the seal 12, and the sleeve 131 are disposed in the second housing 15. The operation part 132 is at least partially exposed outside the second housing 15, that is, the operation part 132 can be partially exposed outside the second housing 15 or can be completely exposed outside the second housing 15. The second housing 15, the seal 12, and the sleeve 131 together define a liquid storage cavity 14. The liquid storage cavity 14 is used to store the atomization matrix. The isolation assembly 13 is used to control the communication between the atomization assembly 11 and the liquid storage cavity 14, so as to control the conversion of the atomization assembly 11 from the non-activated state to the activated state.

[0051] The seal 12 can be an elastic member made of materials such as silica gel and rubber. The seal 12 can also include an elastic member and a reinforcement member embedded in the elastic member. The reinforcement member can be made of a metal material, for example, it can be a steel sheet. The combination of the elastic member and the reinforcement member can increase the overall stiffness of the seal 12, and avoid the deformation of the seal 12 caused by the upward movement of the isolation assembly 13 leading to the leakage of the atomization matrix.

[0052] As Figure 5 shown, in some embodiments, the atomizer further includes a receiving seat 16, and the receiving seat 16 defines a second receiving cavity. When the atomization sleeve 111 is sleeved on the outer periphery of the liquid guide member 112 and the seal 12 is sleeved on the outer periphery of the atomization sleeve 111, the whole formed by the atomization assembly 11, the seal 12, and the atomization sleeve 111 can be received in the second receiving cavity. The control assembly can be installed at the bottom of the receiving seat 16.

[0053] In some embodiments, both the sleeve 131 and the operating portion 132 can be elastic components, for example, made of materials such as silica gel and rubber, so that the sleeve 131 and the operating portion 132 have a sealing function. One end of the sleeve 131 is provided with a first flange 133. When the sleeve 131 contacts other components, it can maintain a tightly fitting state with other components by means of elastic force, so as to achieve a sealing effect. Since the sleeve 131 can be an elastic component and the rigidity of the end of the elastic component is relatively insufficient, there may be a risk of sealing failure at the end of the sleeve 131. Therefore, the first flange 133 is provided to increase the sealing performance of the end of the sleeve 131.

[0054] Please refer to Figure 4 and Figure 5 the orientation shown. The first end 11a of the atomization assembly 11 (atomization sleeve 111), which is also the upper end thereof, and the second end 11b of the atomization assembly 11 (atomization sleeve 111), which is also the lower end thereof. The seal 12 and the sleeve 131 are respectively sleeved on the outer periphery of the atomization assembly 11. Among them, the seal 12 is located between the liquid inlet hole 110 and the second end 11b; the sleeve 131 is located above the seal 12, that is, the sleeve 131 is closer to the first end 11a of the atomization assembly 11 (atomization sleeve 111) relative to the seal 12.

[0055] The seal 12 is sleeved on the outer periphery of the second end 11b, and a buffer gap 40 is defined between the seal 12 and the atomization assembly 11. The buffer gap 40 is used to provide a buffer space for the atomization matrix, thereby shortening the wicking time. The wicking time refers to the preset time that the atomization assembly 11 needs to wait for the atomization matrix to penetrate into the atomization assembly 11 during the first contact with the atomization matrix.

[0056] As Figure 6 shown, in the initial state (that is, when the isolation assembly 13 has not moved, such as the state when the atomizer 1 leaves the factory), the sleeve 131 is sleeved on the outer periphery of the first end 11a and covers the liquid inlet hole 110. One end of the sleeve 131 with the first flange 133 extends into the buffer gap 40, and the first flange 133 abuts against the inner wall of the seal 12.

[0057] The isolation assembly 13 can move away from the seal 12. That is, the isolation assembly 13 can move along the direction away from the seal 12. During the movement of the isolation assembly 13, the atomizer 1 includes at least two states: the first state and the second state.

[0058] As Figure 7 shown, in the first state, the first flange 133 releases the abutment against the inner wall of the seal 12, and the sleeve 131 covers the liquid inlet hole 110. As Figure 8 shown, in the second state, the sleeve 131 releases the coverage of the liquid inlet hole 110, so that the liquid storage cavity 14 communicates with the liquid inlet hole 110.

[0059] Specifically, please refer to Figures 6 to 8 together. The initial state, the first state, and the second state may be arranged in chronological order:

[0060] As Figure 6 shown, 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 hole 110, so that the liquid storage cavity 14 is not communicated with the liquid inlet hole 110. Since the liquid storage cavity 14 is not communicated with the liquid inlet hole 110, the atomization core cannot contact the atomization matrix in the liquid storage cavity 14 for the time being. Therefore, the initial state also belongs to the state where the atomization core of the atomization assembly 11 is not activated. At this time, the first flange 133 of the sleeve 131 is located in the buffer gap 40, and the abutment between the first flange 133 and the seal 12 improves the sealing performance of the end of the sleeve 131, avoiding the sealing failure between the liquid storage cavity 14 and the liquid inlet hole 110 before the atomization core is activated due to insufficient rigidity at the end of the sleeve 131.

[0061] As Figure 7 shown, in the first state, the first flange 133 is separated from the seal 12, so that the buffer space is communicated with the liquid storage cavity 14. That is, the atomization matrix in the liquid storage cavity 14 can start to enter the buffer space. The sleeve 131 still covers the liquid inlet hole 110, so that the liquid storage cavity 14 is not communicated with the liquid inlet hole 110. The buffer space is also not communicated with the liquid inlet hole 110. Since the liquid storage cavity 14 is still not communicated with the liquid inlet hole 110, the atomization assembly 11 still cannot contact the atomization matrix in the liquid storage cavity 14. Therefore, the second state also belongs to the state where the atomization assembly 11 is not activated. The arrows in the figure indicate the approximate flow direction of the atomization matrix.

[0062] As Figure 8 shown, in the second state, the first flange 133 is separated from the seal 12, and the sleeve 131 is separated from the liquid inlet hole 110, so that the buffer space, the liquid storage cavity 14, and the liquid inlet hole 110 are communicated. At this time, the atomization matrix cached in the buffer space and the atomization matrix in the liquid storage cavity 14 both flow into the liquid inlet hole 110 together. Because a certain amount of atomization matrix is cached in the buffer space in advance, when the sleeve 131 is separated from the liquid inlet hole 110, the atomization matrix can quickly enter the atomization sleeve 111 of the atomization assembly 11, thereby shortening the wicking time. The arrows in the figure indicate the approximate flow direction of the atomization matrix.

[0063] Please continue to refer to Figure 4 and Figure 5, in some embodiments, the atomizer 1 further includes a second housing 15, which includes a connected main body portion 151 and a nozzle inner tube 152. The main body portion 151, as the outer housing, encloses the atomization assembly 11, the seal 12, and the sleeve 131 therein. The nozzle inner tube 152 is disposed inside the main body portion 151 and is connected to the sleeve 131. The nozzle inner tube 152 defines an air outlet channel 153 (please refer to Figure 12 and Figure 13 ). The end of the air outlet channel 153 is the air outlet end of the atomization device. The aerosol generated at the atomization 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.

[0064] The main body portion 151 is sleeved on the outer periphery of the seal 12. The main body portion 151, the seal 12, the sleeve 131, and the nozzle inner tube 152 together define a liquid storage cavity 14. The sleeve 131 is sleeved on the outer periphery of the operation portion 132, and the operation portion 132 is detachably disposed in the air outlet channel 153.

[0065] As shown in Figure 9 and Figure 10 , referring to the up and down directions shown in the figures, in some embodiments, the operation portion 132 includes a pull rod. The sleeve 131 is connected to the outer periphery of the pull rod. The pull rod passes through the air outlet channel 153 and part of it is located outside the second housing 15. The pull rod can be physically separated from the sleeve 131 and removed under the action of an external force. Specifically, the sleeve 131 and the outer periphery of the pull rod are connected by a connecting portion 41. A groove 42 is also formed between the outer peripheries of the sleeve 131 and the nozzle inner tube 152. The groove 42 penetrates 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 portion 41. One end of the nozzle inner tube 152 away from the main body portion 151 is embedded in the groove 42. During the process of the pull rod moving upward relative to the atomization assembly 11, the lower end portion of the nozzle inner tube 152 (i.e., the end of the nozzle inner tube 152 away from the main body portion 151) gradually approaches the connecting portion 41 and can finally abut against the connecting portion 41. The connecting portion 41 has a relatively small thickness so that it can be broken under the action of the lower end portion of the nozzle inner tube 152, separating the sleeve 131 and the pull rod.

[0066] In other embodiments, the operation portion 132 may also include a push rod disposed below the sleeve 131 (such as the bottom of the second housing 15), or a push block exposed on the side of the second housing 15, etc., as long as the operation portion 132 is connected to the sleeve 131 and can drive the sleeve 131 to move.

[0067] Please refer to Figure 4 , Figures 6 to 8 , Figures 11 to 13 . Figure 4 and Figure 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, Figure 13 shows the fifth state of the atomizer. The initial state to the fifth state can be arranged in chronological order, that is, six position states during the upward movement of the operation part 132 are shown from the initial state to the fifth state.

[0068] Figure 4 and Figure 6 is the initial state, that is, the state where the atomization assembly 11 is not activated. At this time, the liquid storage cavity 14 and the liquid inlet hole 110 are not connected. Continuing to pull the operation part 132 upward at this time, the sleeve 131 and the operation part 132 move upward together until reaching Figure 11 the third state, the liquid inlet hole 110 is connected to the liquid storage cavity 14, and the atomization assembly 11 is in an activated state; and, the lower end of the inner tube 152 of the nozzle fitted in the groove 42 just abuts against the connecting part 41. Continuing to pull the operation part 132 upward at this time, the connecting part 41 is broken by the downward force provided by the inner tube 152 of the nozzle, as Figure 12 shown, in the fourth state of the atomizer, the sleeve 131 and the operation part 132 are separated. As Figure 13 shown, continuing to pull the operation part 132 upward, in the fifth state of the atomizer, the operation part 132 is separated from the air outlet channel 153, while the sleeve 131 continues to be sleeved on the outer peripheral surface of the inner tube 152 of the nozzle.

[0069] Thus, when the atomization assembly 11 is not activated, for example, during transportation, the air outlet channel 153 can be blocked by the operation part 132 to prevent external pollutants from entering the air outlet channel 153, acting as a dust plug. When it is necessary to activate the atomizer 1, the user only needs to pull the operation part 132 upward until the atomization assembly 11 enters the activated state, and then take out the operation part 132. The process of activating the atomization assembly 11 is simple and reliable.

[0070] As Figure 9 and Figure 10As shown, in some embodiments, the seal 12 includes a first inner surface 121 and a second inner surface 122 facing the atomization sleeve 111. The first inner surface 121 contacts the outer periphery of the atomization sleeve 111 and is used to fix the relative position between the seal 12 and the atomization sleeve 111. The second inner surface 122 is used to define a buffer gap 40 with the atomization sleeve 111. The seal 12 is annular, and the cross-sectional dimension of the cavity surrounded by the second inner surface 122 is larger than the cross-sectional dimension of the cavity surrounded by the first inner surface 121. In the initial state, the first flange 133 abuts against the second inner surface 122; in the first state, the first flange 133 is separated from the second inner surface 122.

[0071] As Figures 6 to 10 shown, in some embodiments, the seal 12 further includes a first end face 123 and a second end face 124. Taking the orientation in Figure 9 and Figure 10 as a reference, 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 connected to 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 connection between the first end face 123 and the second inner surface 122, and the drainage portion 51 includes an arc surface and / or an inclined surface facing the atomization sleeve 111. That is, the drainage portion 51 may include one of the arc surface and the inclined surface, or a combination of both. Both the arc surface and the inclined surface face the atomization sleeve 111. That is, the inclined surface is inclined towards the atomization sleeve 111. For example Figures 6 to 8 in the shown embodiment, there is an inclined surface at the connection between the first end face 123 and the second inner surface 122, and this inclined surface serves as the drainage portion 51. When the liquid storage cavity 14 is communicated with the buffer gap 40, the atomization matrix can be guided to the buffer gap 40 through this inclined surface, which is beneficial to accelerating the flow rate of the atomization matrix among the liquid storage cavity 14, the buffer gap 40, and the liquid inlet hole 110, and is beneficial to achieving the effect of rapid wicking. In some other embodiments, the arc surface can also play a similar role as the inclined surface, which will not be elaborated here.

[0072] As Figures 6 to 10 shown, in some embodiments, the second inner surface 122 includes at least one first inclined portion 52, and the first inclined portion 52 also includes an arc surface and / or an inclined surface facing the atomization sleeve 111. That is, the first inclined portion 52 may include one of the arc surface and the inclined surface, or a combination of both. The number of the first inclined portions 52 may be one or more than one, and the present application does not limit this.

[0073] As Figures 6 to 10As shown, in some embodiments, the sleeve 131 is provided with a second inclined portion 53 on the outer periphery of the end of the end where the first flange 133 is located. The second inclined portion 53 also includes an arc surface and / or an inclined surface facing the seal 12. That is, the second inclined portion 53 may include one of an arc surface and an inclined surface, or a combination of both. Taking Figure 10 the orientation in Figure 6 as a reference, the second inclined portion 53 is located below the first flange 133. As Figure 7 shown, in the initial state, the second inclined portion 53 may be in contact with 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 kept matching. For example, both include an inclined surface, or both include an arc surface, and the two inclined surfaces or the two arc surfaces are in the same shape and are adapted to each other. Thus, the end of the sleeve 131 can be closely attached to the first inclined portion 52 of the seal 12 through the second inclined portion 53, and the two can maintain a good sealing and fitting effect, further strengthening the sealing effect between the liquid storage cavity 14 and the liquid inlet hole 110 in the initial state. As Figure 7 shown, in the first state, the first inclined portion 52 guides the atomization matrix to quickly flow from the liquid storage cavity 14 to and fill the buffer gap 40 along the flow direction of the atomization matrix. And, as

[0074] shown in Figures 6 to 10 , in some embodiments, the sleeve 131 is further provided with a third inclined portion 54 facing the atomization sleeve 111 at the end of the end where the first flange 133 is located. The third inclined portion 54 also includes an arc surface and / or an inclined surface facing the atomization sleeve 111. That is, the third inclined portion 54 may include one of an arc surface and an inclined surface, 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 atomization sleeve 111), and the third inclined portion 54 is located on the side of the sleeve 131 facing the atomization sleeve 111 (that is, the side facing away from the seal 12).

[0075] 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 component 13. Moreover, 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 enhance the sealing effect between the sleeve 131 and the seal 12.

[0076] As Figures 6 to 10 shown, in some embodiments, at least one circle of second flanges 134 is further provided on the inner wall of the sleeve 131. That is, one circle of second flanges 134 can be provided on the inner wall of the sleeve 131, or multiple circles (two circles or more than two circles) of second flanges 134 can be provided. The second flanges 134 and the first flanges 133 are located at the same end of the sleeve 131 (that is, the lower end in the figure), the second flanges 134 are located on the side of the sleeve 131 facing the atomizing sleeve 111, and the first flanges 133 are located on the side of the sleeve 131 facing away from the atomizing sleeve 111. Both the first flanges 133 and the second flanges 134 can be structures protruding transversely. The transverse direction can refer to the direction perpendicular to the axial direction, and this axial direction can refer to Figures 10 to 13 the up-and-down direction shown, 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.

[0077] At least in the initial state and the first state, the second flanges 134 are in contact with the atomizing sleeve 111. That is, as Figure 6 and Figure 7 shown, in the initial state and the first state, on one side of the atomizing sleeve 111, by the contact between the second flanges 134 and the atomizing sleeve 111, the liquid inlet hole 110 is not communicated with the buffer gap 40 and the liquid inlet hole 110 is not communicated with the liquid storage cavity 14, thereby maintaining the unactivated state of the atomizing component 11. As Figure 6 shown, in the initial state, the first flanges 133 are in contact with the second inner surface 122 of the seal 12, and the second flanges 134 are in contact with the atomizing sleeve 111. Through the contact forces on both sides, the sealing performance of the lower end portion of the sleeve 131 is significantly enhanced. When the first flanges 133 and the second flanges 134 are provided simultaneously, the first flanges 133 and the second flanges 134 jointly improve the sealing performance of the lower end portion of the sleeve 131, avoiding the sealing failure between the liquid storage cavity 14 and the liquid inlet hole 110 before the atomizing core is activated due to insufficient rigidity of the lower end portion of the sleeve 131.

[0078] As Figure 10 shown, in some embodiments, at least one circle of third flanges 135 is further provided on the inner wall of the sleeve 131. That is, one circle of third flanges 135 can be provided on the inner wall of the sleeve 131, or multiple circles (two circles or more than two circles) of third flanges 135 can be provided. Refer to Figure 10For the azimuth indication, the third flange 135 is located above the second flange 134, and the liquid inlet hole 110 is located between the second flange 134 and the third flange 135. Thus, in the initial state, good sealing can be ensured on both the upper and lower sides of the liquid inlet hole 110, effectively preventing the sealing failure before the atomization core is activated.

[0079] The above uses specific examples to elaborate on the present utility model, which is only used to help understand the present utility model and is not intended to limit the present utility model. For those skilled in the technical field to which the present utility model belongs, several simple deductions, deformations or substitutions can also be made according to the idea of the present utility model.
