[0002] High-capacity electronic cigarettes typically include a detachable e-liquid bottle that stores a large amount of e-liquid and supplies it to the atomizing device. The atomizing device, controlled and powered by an electronic control unit, vaporizes the e-liquid, and the atomized vapor flows out through a mouthpiece connected to the atomizing chamber for the user to inhale.

[0003] The atomizing device has an oil tank inside. In existing electronic atomizers, the plugs on the oil tank and the oil bottle need to be removed separately before the oil tank and the oil bottle can be reassembled. After the oil tank and the oil bottle are separated, the plugs need to be put back into the oil tank and the oil bottle, which is a cumbersome operation. Utility Model Content

In the assembled state, the oil tank, the first valve assembly, the second valve assembly, and the oil bottle are connected in sequence, and the first movable part and the second movable part are connected. Compared with the detached state, the position of the first movable part is closer to the inside of the oil tank, and the position of the second movable part is closer to the inside of the oil bottle.

[0012] Optionally, the first fixed cylinder has a first oil passage hole, the first movable part is cylindrical and has a second oil passage hole, and the port of the first fixed cylinder and / or the first movable part near the inside of the oil tank is closed.

[0013] In the disassembled state, the second oil passage is staggered with the first oil passage, and the second oil passage is closer to the mounting cylinder than the first oil passage. In the assembled state, the oil tank, the first oil passage, and the second oil passage are connected in sequence.

[0014] Optionally, the electronic atomizer includes:

[0015] A movable ball is disposed within the first movable component. The movable ball is capable of moving within the first movable component. The movable ball is used to close the end of the first movable component away from the interior of the oil tank. The connecting force between the first fixed cylinder and the first movable component is greater than the weight of the movable ball.

[0016] Optionally, the first valve assembly includes a first elastic element for preventing the first movable element from moving toward the interior of the oil tank.

[0017] Optionally, the port at the end of the first fixed cylinder near the interior of the oil tank is open, and the port at the end of the first movable member near the interior of the oil tank is closed. The electronic atomizer includes:

[0018] The mounting base is sleeved on the outside of the first valve assembly. The mounting base has an oil passage relative to the first oil passage. The two ends of the first elastic member are respectively connected to the end of the first movable member near the inside of the oil tank and the mounting base.

[0019] Optionally, the electronic atomizer includes:

[0020] A movable ball is disposed within the first movable component. The movable ball is capable of moving within the first movable component. The movable ball is used to close the end of the first movable component away from the interior of the oil tank. The elastic force of the first elastic component is greater than the weight of the movable ball.

[0021] Optionally, the second fixed cylinder is sleeved inside the mouth of the oil bottle, the second movable part is cylindrical, and a third oil passage is opened at one end of the second movable part near the inside of the oil bottle and the port is closed.

[0025] Optionally, the electronic atomizer includes:

[0026] A movable ball, connected to the first valve assembly and movable relative to the first valve assembly, in the assembled state, is used to close the end of the second movable member away from the inside of the oil bottle.

[0027] In the electronic atomizer of this application, when the electronic atomizer is detached, the first valve assembly seals the connection between the oil tank and the outside, and the second valve assembly seals the connection between the oil bottle and the outside. Therefore, when the oil tank and oil bottle are not assembled, the atomizing matrix inside will not leak. When the electronic atomizer is assembled, the first movable part of the first valve assembly connects to the second movable part of the second valve assembly, thus connecting the first and second valve assemblies. During the connection process, the first movable part pushes the second movable part towards the inside of the oil bottle, connecting the oil bottle to the second valve assembly; simultaneously, the second movable part pushes the first movable part towards the inside of the oil tank, connecting the oil tank to the first valve assembly. Thus, the oil tank, the first valve assembly, the second valve assembly, and the oil bottle can be sequentially connected, making the assembly of the oil tank and oil bottle of the electronic atomizer of this application convenient.

[0028] In the electronic atomizer of this application, a movable ball is provided inside the first movable component. When the electronic atomizer is upright, the movable ball moves to the end of the first movable component away from the inside of the oil tank under the influence of gravity. The movable ball closes the connection between the first valve assembly and the second valve assembly, preventing the atomizing matrix and gas from flowing between the oil tank and the oil bottle. The atomizing matrix is ​​not easily leaked, and the content of the atomizing matrix in the oil tank can be controlled. When the electronic atomizer is inverted, the movable ball moves away from the end of the first movable component away from the inside of the oil tank under the influence of gravity. The first valve assembly and the second valve assembly are connected, and the atomizing matrix in the oil bottle flows into the oil tank, realizing oil filling. Attached Figure Description

[0040] This application discloses an electronic atomizer, comprising a housing, a mounting tube, an oil bottle, a first valve assembly, and a second valve assembly. An oil tank is formed inside the housing. The mounting tube passes through the housing and communicates with the oil tank. The oil bottle is detachably connected to the end of the mounting tube near the outside of the housing. The first valve assembly includes a first fixed tube and a first movable member. One end of the first fixed tube is fixedly connected to the end of the mounting tube near the inside of the housing, and the first movable member is disposed within the first fixed tube and is axially movable along the first fixed tube. The second valve assembly includes a second fixed tube and a second movable member. The second fixed tube is fixedly connected to the mouth of the oil bottle, and the second movable member is disposed within the second fixed tube and is axially movable along the second fixed tube. The electronic atomizer has a detached state and an assembled state. In the detached state, the first valve assembly closes the communication between the oil tank and the outside, and the second valve assembly closes the communication between the oil bottle and the outside. In the assembled state, the oil tank, the first valve assembly, the second valve assembly, and the oil bottle are sequentially connected, and the first and second movable members are connected. Compared to the detached state, the first movable member is positioned closer to the inside of the oil tank, and the second movable member is positioned closer to the inside of the oil bottle.

[0041] In the electronic atomizer of this application, when the electronic atomizer is detached, the first valve assembly seals the connection between the oil tank and the outside, and the second valve assembly seals the connection between the oil bottle and the outside. Therefore, when the oil tank and oil bottle are not assembled, the atomizing matrix inside will not leak. When the electronic atomizer is assembled, the first movable part of the first valve assembly connects to the second movable part of the second valve assembly, thus connecting the first and second valve assemblies. During the connection process, the first movable part pushes the second movable part towards the inside of the oil bottle, connecting the oil bottle to the second valve assembly; simultaneously, the second movable part pushes the first movable part towards the inside of the oil tank, connecting the oil tank to the first valve assembly. Thus, the oil tank, the first valve assembly, the second valve assembly, and the oil bottle can be sequentially connected, making the assembly of the oil tank and oil bottle of the electronic atomizer of this application convenient.

[0042] The following will mainly describe the specific structure of the electronic atomizer.

[0043] Please see Figures 1 to 4 The electronic atomizer 100 of this application includes a housing 110, and an oil reservoir 111 is formed inside the housing 110. The housing 110 includes an upper shell 113 and a lower shell 114, and the oil reservoir 111 is formed by the upper shell 113 and the lower shell 114. The electronic atomizer 100 of this application may include an atomizing component 170, which is disposed within the oil reservoir 111.

[0044] Please see Figures 1 to 4 The electronic atomizer 100 of this application includes a mounting tube 120. The mounting tube 120 passes through the outer shell 110 and communicates with the oil tank 111. The mounting tube 120 and the outer shell 110 can be integrally formed or detachably connected (adhesive, screw, or snap-fit). One end of the mounting tube 120 near the outside of the outer shell 110 can extend out of the outer shell 110, be flush with the outer shell 110, or be located inside the outer shell 110.

[0045] Please see Figures 1 to 4 The electronic atomizer 100 of this application includes an oil bottle 130. The oil bottle 130 includes a bottle opening through which the atomizing matrix inside the oil bottle 130 can flow out. The bottle opening is connected to the end of the mounting tube 120 near the outside of the outer casing 110. The bottle opening and the mounting tube 120 can be detachably sleeved, or further, can be glued, screwed, or snap-fitted.

[0046] Please see Figures 1 to 4 The electronic atomizer 100 of this application includes a first valve assembly 140 and a second valve assembly 150. The first valve assembly 140 includes a first fixed cylinder 141 and a first movable member 142. One end of the first fixed cylinder 141 is fixedly connected to the end of the mounting cylinder 120 near the interior of the outer casing 110. The first movable member 142 is disposed within the first fixed cylinder 141 and is movable along the axial direction of the first fixed cylinder 141. The second valve assembly 150 includes a second fixed cylinder 151 and a second movable member 152. The second fixed cylinder 151 is fixedly connected to the mouth of the oil bottle 130. The second movable member 152 is disposed within the second fixed cylinder 151 and is movable along the axial direction of the second fixed cylinder 151.

[0047] The electronic atomizer 100 has both a detached and an assembled state. Please refer to [link / reference]. Figure 2 In the disassembled state, the first valve assembly 140 seals the connection between the oil tank 111 and the outside, and the second valve assembly 150 seals the connection between the oil bottle 130 and the outside. Therefore, when the oil tank 111 and oil bottle 130 are not assembled, the atomizing matrix inside them will not leak.

[0048] Please see Figure 3 and Figure 4In the assembled state, the oil tank 111, the first valve assembly 140, the second valve assembly 150, and the oil bottle 130 are sequentially connected, and the first movable part 142 and the second movable part 152 are connected. Compared to the disassembled state, the first movable part 142 is closer to the interior of the oil tank 111, and the second movable part 152 is closer to the interior of the oil bottle 130. When the electronic atomizer 100 is assembled, the first movable part 142 of the first valve assembly 140 connects to the second movable part 152 of the second valve assembly 150, connecting the first valve assembly 140 and the second valve assembly 150. During the connection process, the first movable part 142 pushes the second movable part 152 toward the interior of the oil bottle 130, connecting the oil bottle 130 and the second valve assembly 150. Simultaneously, the second movable part 152 pushes the first movable part 142 toward the interior of the oil tank 111, connecting the oil tank 111 and the first valve assembly 140. Therefore, the assembly of the oil tank 111 and oil bottle 130 of the electronic atomizer 100 of this application is convenient.

[0049] Please see Figures 2 to 4 The first fixed cylinder 141 is sleeved inside the end of the mounting cylinder 120 near the interior of the oil tank 111. The first fixed cylinder 141 and the mounting cylinder 120 can be connected by interference fit, adhesive, snap-fit, or screw. The first fixed cylinder 141 has a first oil passage hole 411. The first movable member 142 is cylindrical and has a second oil passage hole 421. The end of the first movable member 142 near the interior of the oil tank 111 is closed. There can be multiple second oil passage holes 421, and the shape of the second oil passage holes 421 can be strip-shaped. In the disassembled state, the second oil passage holes 421 and the first oil passage holes 411 are staggered, and the second oil passage holes 421 are closer to the mounting cylinder 120 than the first oil passage holes 411. In the assembled state, the oil tank 111, the first oil passage hole 411, and the second oil passage hole 421 are connected in sequence.

[0050] Please see Figures 1 to 4 The first valve assembly 140 includes a first elastic element 144, one end of which is connected to a first movable element 142. The first elastic element 144 is used to prevent the first movable element 142 from moving toward the interior of the oil reservoir 111. The first elastic element 144 may be a spring.

[0051] In one embodiment, the port of the first fixed cylinder 141 near the interior of the oil tank 111 is also closed, and the two ends of the first elastic member 144 are respectively connected to the end of the first fixed cylinder 141 near the interior of the oil tank 111 and the end of the first movable member 142 near the interior of the oil tank 111, so that the first elastic member 144 can prevent the first movable member 142 from moving toward the interior of the oil tank 111.

[0052] Please see Figures 1 to 4In another embodiment, the port of the first fixed cylinder 141 near the interior of the oil tank 111 is open. The electronic atomizer 100 includes a mounting base 160 connected to the inner wall of the oil tank 111. The bottom end of the atomizing assembly 170 is inserted into the mounting base 160. The mounting base 160 is sleeved on the outside of the first valve assembly 140. The mounting base 160 has an oil passage relative to the first oil passage 411. The two ends of the first elastic member 144 are respectively connected to the end of the first movable member 142 near the interior of the oil tank 111 and the mounting base 160, so that the first elastic member 144 can prevent the first movable member 142 from moving towards the interior of the oil tank 111. The oil passage can guide the flow of the atomizing matrix, so that the atomizing matrix can flow from the first oil passage 411 to the atomizing assembly 170 in a better manner.

[0053] Please see Figures 1 to 4 In the above embodiment, the end face of the first movable member 142 facing the mounting base 160 is recessed in a direction away from the mounting base 160 to form a connecting groove 423, and the end of the first elastic member 144 away from the mounting base 160 is connected to the bottom of the connecting groove 423. The connecting groove 423 can limit and guide the deformation of the first elastic member 144, so that the first elastic member 144 effectively prevents the first movable member 142 from moving into the oil tank 111.

[0054] Please see Figures 1 to 4 The electronic atomizer 100 includes a movable ball 143, which is disposed within a first movable member 142. The movable ball 143 is movable within the first movable member 142 and serves to close one end of the first movable member 142 away from the interior of the oil tank 111. See also... Figure 3 When the electronic atomizer 100 is upright, the movable ball 143 moves to the end of the first movable part 142 away from the inside of the oil tank 111 under the influence of gravity. The movable ball 143 closes the connection between the first valve assembly 140 and the second valve assembly 150. The atomizing matrix and gas will not flow between the oil tank 111 and the oil bottle 130. The atomizing matrix is ​​not easy to leak and the content of the atomizing matrix in the oil tank 111 can be controlled.

[0055] Please see Figure 4 When the electronic atomizer 100 is inverted, the movable ball 143 is moved away from the end of the first movable part 142 away from the inside of the oil tank 111 by gravity. The length of the second oil passage 421 in the axial direction of the first movable part 142 is greater than the diameter of the movable ball 143. That is, the second oil passage 421 is not completely closed by the movable ball 143, and the first oil passage 411 is also not completely closed by the movable ball 143. The first valve assembly 140 is connected to the second valve assembly 150, and the atomizing matrix in the oil bottle 130 flows into the oil tank 111 to realize oil filling.

[0056] In one embodiment, the first valve assembly 140 does not include the first elastic element 144, and the connecting force between the first fixed cylinder 141 and the first movable element 142 is greater than the weight of the movable ball 143. The first fixed cylinder 141 and the first movable element 142 can be interference-fitted, snap-fitted, or adhesively bonded. In another embodiment, the first valve assembly 140 includes the first elastic element 144, and the elastic force of the first elastic element 144 is greater than the weight of the movable ball 143. Therefore, when the electronic atomizer 100 is in the detached state, even if the electronic atomizer 100 is inverted, the movable ball 143 will not push the first movable element 142 toward the interior of the oil tank 111, thus the first valve assembly 140 can remain closed, and the atomizing matrix inside the oil tank 111 will not leak.

[0057] Please see Figures 2 to 4 The end face of the first movable part 142, away from the interior of the oil tank 111, has a first opening 422. Please refer to [link / reference]. Figure 2 and Figure 3 The movable ball 143 can close the first opening 422. Understandably, the area of ​​the first opening 422 should be smaller than the maximum cross-sectional area of ​​the movable ball 143 so that it can be closed by the movable ball 143.

[0058] Please see Figures 2 to 4 The second fixing cylinder 151 is fitted inside the mouth of the oil bottle 130. The second fixing cylinder 151 and the oil bottle 130 can be connected by interference fit, adhesive, or snap-fit. The second movable part 152 is cylindrical, and a third oil passage 521 is opened at one end of the second movable part 152 near the inside of the oil bottle 130, and the end is closed. Please refer to [link / reference]. Figure 2 In the detached state, the second fixing cylinder 151 seals the third oil passage 521. Please refer to [link / reference]. Figure 3 and Figure 4 In the assembled state, the end of the second movable part 152 near the inside of the oil bottle 130 extends out of the end of the second fixed cylinder 151 near the inside of the oil bottle 130, and the third oil passage 521 is at least partially located outside the second fixed cylinder 151 and communicates with the oil bottle 130.

[0059] Please see Figure 3 In the assembled state, the movable ball 143 can close the end of the second movable part 152 away from the interior of the oil bottle 130. For details, please refer to... Figures 2 to 4 The second movable component 152 has a second opening 523 on its end face away from the interior of the oil tank 111, and the movable ball 143 can close the second opening 523. The second opening 523 can be an open port. Thus, in the assembled state, when the electronic atomizer 100 is upright, the movable ball 143 can simultaneously close the connection between the first valve assembly 140 and the outside world and the connection between the second valve assembly 150 and the outside world, making the atomizing matrix less prone to leakage.

[0060] Please see Figures 1 to 4 The second valve assembly 150 includes a second elastic member 153, which prevents the second movable member 152 from moving toward the interior of the oil bottle 130. This prevents leakage of the atomizing matrix from the oil bottle 130. See also... Figures 2 to 4 The inner wall of the second fixed cylinder 151, near the interior of the oil bottle 130, protrudes towards the second movable member 152, forming a first abutment platform 511. The outer wall of the second movable member 152, away from the interior of the oil bottle 130, protrudes towards the second fixed cylinder 151, forming a second abutment platform 522. The second elastic member 153 is sleeved between the second fixed cylinder 151 and the second movable member 152, with its two ends connected to the first abutment platform 511 and the second abutment platform 522, respectively. Thus, the second elastic member 153 can achieve the technical effect of preventing the second movable member 152 from moving towards the interior of the oil bottle 130. The second elastic member 153 can be a spring. The first abutment platform 511 and the second abutment platform 522 can be annular, thus providing a good limiting effect on the second elastic member 153.

[0061] Please see Figures 1 to 4 The second valve assembly 150 includes a limiting member 154 for preventing the second movable member 152 from disengaging from the end of the second fixed cylinder 151 away from the interior of the oil bottle 130. The limiting member 154 is located at the end of the second movable member 152 near the interior of the oil bottle 130 and outside the end of the second fixed cylinder 151 near the interior of the oil bottle 130. The limiting member 154 may be annular and may be sleeved onto the end of the second movable member 152 near the interior of the oil bottle 130.

[0062] The above description is merely a preferred embodiment of this application and does not limit the patent scope of this application. Any equivalent structural transformations made based on the inventive concept of this application and the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this application.
