Furthermore, when the movable member moves from the first position to the second position, the movable member applies a compressive force to the elastic member, causing the elastic member to elastically deform. When the compressive force applied by the movable member to the elastic member is released, the elastic member recovers its elastic deformation and generates an elastic restoring force. Under the action of this elastic restoring force, the movable member returns from the second position to the first position, thereby resealing the liquid outlet. This prevents leakage of the liquid matrix stored in the liquid reservoir during replacement of the liquid reservoir.

Throughout the description of this application, "plurality" means at least two, such as two, three, etc., unless otherwise specifically defined.

[0043] An embodiment of the present application provides an electronic atomization device 100, such as Figures 1-3 As shown, the electronic atomization device 100 includes a liquid reservoir 10 and an atomizer 20, which are detachably connected. A first liquid storage chamber 11 and a liquid outlet 12 are provided in the liquid reservoir 10. The first liquid storage chamber 11 stores an atomizable liquid matrix, and the liquid outlet 12 is used to allow the liquid matrix in the first liquid storage chamber 11 to flow out of the liquid reservoir 10.

[0044] The nebulizer 20 includes a second liquid storage chamber 21, which is also used to store a liquid matrix that can be atomized. The nebulizer 20 also includes an atomizing assembly 22, which is used to atomize the liquid matrix from the second liquid storage chamber 21 to generate an aerosol. Furthermore, the nebulizer 20 also includes a longitudinally extending air outlet portion 24, which defines an air outlet hole 241 for allowing the aerosol to escape from the nebulizer 20. The air outlet hole 241 is in fluid communication with the atomizing assembly 22, so that the aerosol formed after atomization by the atomizing assembly 22 can flow into the air outlet hole 241, and the user can inhale the aerosol by drawing on the air outlet hole 241.

[0045] The atomization assembly 22 includes a liquid guide 221 and a heating element 222 coupled to the liquid guide 221. A liquid storage component 212 is provided in the liquid storage chamber 21. The liquid guide 221 and the liquid storage component 212 are in contact with each other, so that the liquid storage component 212 can further transfer the stored liquid matrix to the liquid guide 221. The heating element 222 on 221 can heat and atomize the liquid matrix to generate an aerosol.

[0046] Both the liquid storage member 212 and the liquid guide member 221 are made of a porous material, which can be any of cotton fibers, non-woven fabrics, fiberglass ropes, porous glass, or porous ceramics. Thus, the liquid storage member 212 and the liquid guide member 221 can absorb or conduct liquid substrates through their internal microporous structures or voids. Accordingly, the heating element 222 can be incorporated into the liquid guide member 221 through printing, deposition, sintering, or physical assembly, or can be wound around the liquid guide member 221.

[0047] The atomizer 20 also includes a battery cell 25 and a main board 26. The main board 26 is provided with a controller of the electronic atomization device 100. The battery cell 25 and the heating element 222 are electrically connected to the controller, so that the controller can control the battery cell 25 to provide the heating element 222 with the electrical energy required for heating and atomization.

[0048] In other embodiments, the atomizing component may further include an ultrasonic atomizing component, which is capable of generating ultrasonic waves and utilizing ultrasonic waves to form a liquid matrix into an aerosol. The atomizing component may also be other components capable of forming a liquid matrix into an aerosol, and the present application does not impose specific restrictions on the type of atomizing component. The liquid reservoir 10 also includes a movable part 13, which is disposed adjacent to the liquid storage hole 12, and the movable part 13 can be driven to move between a first position and a second position. Before the liquid reservoir 10 and the atomizer 20 are connected, the movable part 13 is in the first position, at which time the movable part 13 seals the liquid outlet 12, and the liquid matrix in the first liquid storage chamber 11 cannot flow out through the liquid outlet 12, as shown in FIG. Figure 4 and Figure 5 shown.

[0049] When the liquid reservoir 10 and the atomizer 20 are connected, the movable member 13 is pushed from the first position to the second position by the pushing portion 211 of the atomizer 20. At this time, the movable member 13 is separated from the liquid outlet 12, and the movable member 13 releases the seal of the liquid outlet 12. The liquid matrix in the first liquid storage chamber 11 can flow out of the liquid reservoir 10 through the liquid outlet 12 and further flow into the second liquid storage chamber 21 to replenish the liquid matrix in the second liquid storage chamber 21. Figure 3 and Figure 6 shown.

[0050] In a specific embodiment, Figure 3 and Figure 4As shown, the atomizer 20 includes a first end portion 210 and a second end portion 220 arranged opposite to each other along its length. The first end portion 210 is used to connect to the liquid reservoir 10. The pushing portion 211 extends longitudinally from the end surface of the first end portion 210. The pushing portion 211 is hollow so as to define a liquid channel 2111 for transferring the liquid matrix in the first liquid storage chamber 11 to the second liquid storage chamber 21. When the atomizer 20 and the liquid reservoir 10 are connected, the pushing portion 211 is inserted into the liquid outlet 12 and pushes the movable member 13 from the first position to the second position, so that the movable member 13 releases the seal on the liquid outlet 12. The liquid matrix in the first liquid storage chamber 11 can then flow into the liquid outlet 12 and flow into the second liquid storage chamber 21 through the liquid channel 2111 in the pushing portion 211. Figure 3 The liquid matrix flow path R is shown in FIG.

[0051] And, in some embodiments, as Figure 4 As shown, the end of the pushing portion 211 that contacts the movable member 13 is provided with a plurality of notches 2112. When the movable member 13 moves from the first position to the second position, the liquid matrix stored in the first liquid storage chamber 11 flows through the notches 2112 into the liquid channel 2111 of the pushing portion 211. Preferably, the width of the notches 2112 is smaller than the inner diameter of the liquid channel 2111 to control the transfer speed of the liquid matrix and prevent the liquid matrix from being transferred too quickly.

[0052] The liquid reservoir 10 also includes an elastic member 143, which is arranged on the side of the liquid outlet 12 facing the first liquid storage chamber 11. Before the liquid reservoir 10 and the atomizer 20 are connected, the elastic member 143 abuts against the movable member 1 to maintain the movable member 13 in the first position, so that the movable member 13 seals the liquid outlet 12 to prevent the liquid matrix in the first liquid storage chamber 11 from leaking out of the liquid reservoir 10 through the liquid outlet 12.

[0053] When the liquid reservoir 10 and the atomizer 20 are connected, the push portion of the atomizer 20 pushes the movable member 13 from the first position to the second position. At this time, the movable member 13 squeezes the elastic member to cause the elastic member to elastically deform. When the liquid reservoir 10 needs to be replaced, the liquid reservoir 10 is removed from the electronic atomization device 100. At this time, the squeezing force on the elastic member is released, and the elastic member recovers its elastic deformation. Under the action of the elastic recovery force, the movable member 13 is pushed back from the second position to the first position, and then the movable member 13 is maintained in the first position, so that the movable member 13 re-seals the liquid outlet 12. This can prevent the remaining liquid matrix in the liquid reservoir 10 from leaking out through the liquid outlet 12 when the liquid reservoir 10 is replaced, thereby improving the user experience.

[0054] In some embodiments, as Figure 5 and Figure 7As shown, the liquid reservoir 10 also includes a sealing member 14 for sealing the first liquid storage chamber 11. The sealing member 14 can be any one of soft rubber members such as silicone, rubber or latex. The sealing member 14 has a first surface 141 and a second surface 142 arranged opposite to each other. The first surface 141 faces the first liquid storage chamber 11. A portion of the liquid outlet 12 is defined by the sealing member 14. The elastic member 143 includes a protrusion formed on the first surface 141, that is, the elastic member is a part of the sealing member 14. The protrusion 143 is hollow, and the movable member 13 is located in the hollow area of ​​the protrusion 143 so as to elastically abut against the top wall 1431 of the protrusion 143.

[0055] Furthermore, before the liquid reservoir 10 and the atomizer 20 are connected, the movable member 13 can be maintained in the first position under the elastic force of the top wall 1431. When the liquid reservoir 10 and the atomizer 20 are connected, the pushing portion of the atomizer 20 pushes the movable member 13 from the first position to the second position, and the movable member 13 applies a squeezing force to the top wall 1431, and the top wall 1431 further elastically deforms under the action of the squeezing force. When the liquid reservoir 10 is removed from the electronic atomization device 100, the squeezing force applied by the movable member 13 to the top wall 1431 is released, and the top wall 1431 recovers its elastic deformation and, under the action of the elastic restoring force, pushes the movable member 13 from the second position back to the first position, thereby maintaining the movable member 13 in the first position and allowing the movable member 13 to re-seal the liquid outlet 12.

[0056] In some embodiments, as Figure 7 As shown, the protrusion 143 includes a plurality of connecting arms 1432 connected between the first surface 141 and the top wall 1431. The plurality of connecting arms 1432 surround the movable member 13 and are arranged in sequence at intervals. By providing a plurality of spaced-apart connecting arms 1432, on the one hand, the connection strength of the top wall 1431 can be reduced, thereby making it easier for the top wall 1432 to deform; on the other hand, a gap can be created between any two adjacent connecting arms 1432, and the liquid matrix in the first liquid storage chamber 11 can flow into the liquid outlet 12 through the gap.

[0057] And, in some embodiments, as Figure 7 As shown, multiple connecting arms 1432 are evenly surrounded by the movable part 13, so that when the movable part 13 moves between the first position and the second position, the elastic force generated or released by each connecting arm 1432 is basically the same, so that the movable part 13 will not produce lateral deviation during the movement. The movable part 13 only moves between the first position and the second position in the longitudinal direction, which can improve the sealing effect of the movable part 13 in resealing the liquid outlet 12.

[0058] It should be noted that the elastic member may not be part of the sealing member 14. In some embodiments, an independent elastic member may be used to enable the movable member 13 to reseal the liquid outlet 12. For example, an independent spring, shrapnel, or any one of elastic silicone, rubber, etc. may be used.

[0059] In some embodiments, as Figure 6 As shown, the movable member 13 is a sphere, and the wall of the liquid outlet 12 is formed with a curved surface 121. When the movable member 13 is in the first position, the sphere and the curved surface 121 are tightly fitted together under the force of the elastic member, thereby sealing the liquid outlet 12. When the movable member 13 moves from the first position to the second position, the sphere and the curved surface 121 separate, thereby releasing the seal of the liquid outlet 12.

[0060] In some embodiments, as Figure 1 and Figure 2 As shown, the liquid reservoir 10 has a third end 110 and a fourth end 120 arranged opposite to each other along its length direction, and a through hole 130 connecting the third end 110 and the fourth end 120. The air outlet portion 24 of the atomizer 20 extends out of the first end 210. When the liquid reservoir 10 and the atomizer 20 are connected, the air outlet portion 24 passes through the through hole 130, so that the end of the air outlet hole 241 is exposed outside the through hole 130 to serve as a nozzle for the user to inhale.

[0061] Further in some embodiments, Figure 2 As shown, the cross-sectional shape of the through hole 130 is non-circular, and thus the air outlet portion 24 of the atomizer 20 can only pass through the through hole 130 in a specific direction along the shape of the through hole 130, that is, the liquid reservoir 10 and the atomizer 20 are connected in a specific direction, so that when the liquid reservoir 10 and the atomizer 20 are connected, the pushing portion on the atomizer 20 can be aligned with the liquid outlet hole 12 and thus push the movable part 13 to move from the first position to the second position, that is, the air outlet portion 24 can only be inserted into the through hole 130 along the direction in which the pushing portion is aligned with the liquid outlet hole 12.

[0062] Alternatively, in some embodiments, a guide groove (not shown) or a guide rib (not shown) is provided on the inner wall of the through hole 130, and the liquid reservoir 10 and the atomizer 20 are connected in a specific direction through the guide groove or the guide rib.

[0063] Furthermore, in some embodiments, Figure 1 and Figure 2 As shown, the through hole 130 is located in the central area of ​​the liquid reservoir 10, so that when the liquid reservoir 10 and the atomizer 20 are connected, the air outlet portion 24 passes through the central area of ​​the liquid reservoir 10, thereby making the air outlet 241 in the central area of ​​the electronic atomization device 100, so as to facilitate the user to inhale.

[0064] And, in some embodiments, as Figure 5 As shown, the first liquid storage chamber 11 is arranged around the through hole 130, thereby increasing the volume of the first liquid storage chamber 11. In some embodiments, as Figure 6 As shown, the inner wall of the liquid outlet hole 12 is provided with a plurality of annular ridges 122, and the plurality of ridges 122 are arranged in sequence along the extension direction of the liquid outlet hole 12. When the liquid reservoir 10 and the atomizer 20 are connected, the pushing portion of the atomizer 20 extends into the liquid outlet hole 12, and the pushing portion and the ridges 122 are interference fit to seal the gap between the inner wall of the liquid outlet hole 12 and the pushing portion, thereby preventing the liquid matrix in the first liquid storage chamber 11 from flowing into the liquid outlet hole 12 and leaking through the gap between the inner wall of the liquid outlet hole 12 and the pushing portion.

[0065] In some embodiments, as Figure 4 As shown, the atomizer 20 further includes a liquid conduit 23 extending toward the second liquid storage chamber 21. The liquid conduit 23 communicates with the liquid channel 2111 of the driving portion 211 to receive the liquid matrix from the liquid channel 2111. The liquid conduit 23 has a liquid outlet (not shown), through which the liquid matrix flowing out of the liquid outlet enters the second liquid storage chamber 21. The liquid reservoir 212 in the second liquid storage chamber 21 blocks the liquid outlet of the liquid conduit 23. When the liquid reservoir 212 is saturated with the liquid matrix, it forms a liquid film at the liquid outlet of the liquid conduit 23. This liquid film prevents air from the second liquid storage chamber 21 from entering the first liquid storage chamber 11, thereby slowing or preventing the liquid matrix in the first liquid storage chamber 11 from continuing to flow into the second liquid storage chamber 21. When the liquid matrix stored in the liquid reservoir 212 is consumed, the liquid film disappears, allowing the liquid matrix in the first liquid storage chamber 11 to continue to flow into the second liquid storage chamber 21.

[0066] In some embodiments, a first magnetic member (not shown) is provided on the liquid reservoir 10, and a second magnetic member (not shown) is provided on the atomizer 20, and the liquid reservoir 10 and the atomizer 20 can be connected to each other by magnetic attraction. Alternatively, in some embodiments, a receiving compartment (shown in the figure) is provided at one end where the atomizer 20 and the liquid reservoir 10 are connected, and the receiving compartment is used to at least partially accommodate the liquid reservoir 10, and a card slot or buckle is provided on the inner wall of the receiving compartment, and a corresponding buckle or card slot is provided on the shell of the liquid reservoir 10, so that the liquid reservoir 10 and the atomizer 20 can be connected by a buckle connection.

[0067] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Based on the concept of the present application, the technical features in the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations in different aspects of the present application as described above. For the sake of simplicity, they are not provided in detail. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present application.
