The terms "first", "second", etc. in the specification and claims of this application or the above drawings are used to distinguish different objects and not to describe a specific order.

[0038] References herein to "embodiments" mean that the particular features, structures, or characteristics described in connection with the embodiments can be included in at least one embodiment of the present application. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0039] Referring to Figures 1 to 5 , an embodiment of the present application provides an electronic cigarette that prevents e-liquid leakage, including a housing 100, a valve body 200, and a rotary drive member 300; an e-liquid chamber 110 and an atomization chamber 120 are provided in the housing 100; the valve body 200 is disposed in the atomization chamber 120 and is provided with a liquid inlet 210, an inner cavity 220, and a liquid outlet 230 that are sequentially communicated; the e-liquid chamber 110 is communicated with the liquid inlet 210; the rotary drive member 300 is disposed in the housing 100 and is connected to the valve body 200; the rotary drive member 300 is configured to drive the valve body 200 to rotate between a first rotation position and a second rotation position; when the valve body 200 is located at the first rotation position, the liquid outlet 230 is communicated with the atomization chamber 120; when the valve body 200 is located at the second rotation position, the liquid outlet 230 is in sealed abutment with the inner wall of the atomization chamber 120.

[0040] In practical applications, when using the electronic cigarette, the valve body 200 can be driven by the rotary drive member 300 to rotate to the first rotation position. At this time, the liquid outlet 230 is communicated with the atomization chamber 120, and the e-liquid in the e-liquid chamber 110 can enter the atomization chamber 120 through the liquid inlet 210 - inner cavity 220 - liquid outlet 230 for atomization to generate smoke for the user to inhale; when the electronic cigarette is not in use, the valve body 200 can be driven by the rotary drive member 300 to rotate to the second rotation position. At this time, the liquid outlet 230 is in sealed abutment with a part of the inner wall of the atomization chamber 120 to close the liquid outlet 230, thereby preventing the e-liquid in the e-liquid chamber 110 from leaking into the atomization chamber 120. On the one hand, it ensures the taste after e-liquid atomization, and on the other hand, it can prevent the phenomenon of e-liquid leakage outside the electronic cigarette.

[0041] Furthermore, the larger the diameter of the liquid outlet 230, the more e-liquid enters the atomization chamber 120 per unit time from the liquid outlet 230 when the valve body 200 is located at the second rotation position; correspondingly, when the valve body 200 is located at the first rotation position, the larger the sealed abutment area between the liquid outlet 230 and the inner wall of the atomization chamber 120 to ensure that the liquid outlet 230 can be completely sealed.

[0042] In some embodiments, when the valve body 200 is located at the first rotation position, the opening direction of the liquid outlet 230 faces the atomization area of the atomization chamber 120.

[0043] Understandably, the atomization area in the atomization chamber 120 is used for atomizing e-liquid; in this embodiment, by setting the opening direction of the liquid outlet 230 towards the atomization area of the atomization chamber 120, on the one hand, the flow time of the e-liquid flowing from the liquid outlet 230 to the atomization area is reduced, thereby improving the atomization efficiency of the e-liquid, and further improving the taste of the atomized smoke; on the other hand, the residue of the e-liquid in other spaces of the atomization chamber 120 can be reduced, and the utilization rate of the e-liquid is improved.

[0044] In some embodiments, the opening direction of the liquid inlet 210 intersects with the opening direction of the liquid outlet 230. In this way, on the one hand, when the valve body 200 rotates to the first rotation position, after the e-liquid enters the inner cavity 220 from the liquid inlet 210, it will turn in the inner cavity 220 and flow out from the liquid outlet 230, forming a guiding control of the flow direction of the e-liquid, so as to slow down the flow speed of the e-liquid, enabling the e-liquid to spread more fully in the atomization chamber 120, improving the distribution uniformity of the e-liquid in the atomization chamber 120, and further improving the atomization effect of the e-liquid; on the other hand, when the valve body 200 rotates to the second rotation position, since the e-liquid needs to experience a change in flow direction when flowing from the liquid inlet 210 to the liquid outlet 230, the e-liquid is restricted by the flow directionality during the process of flowing from the liquid inlet 210 to the liquid outlet 230, and further improves the sealing effect on the e-liquid.

[0045] Exemplarily, the positional relationship between the above-mentioned atomization chamber 120 and the oil chamber 110 is set in a "7" shape; correspondingly, the above-mentioned liquid inlet 210 is disposed opposite to the oil outlet of the oil chamber 110, the opening direction of the above-mentioned liquid outlet 230 is set towards the atomization area of the atomization chamber 120, and the positional relationship between the opening direction of the liquid inlet 210 and the opening direction of the liquid outlet 230 is set in a "7" shape. In this way, the electronic cigarette with this structure simultaneously has the above-mentioned technical effects of "when the valve body 200 is in the first rotation position, the opening direction of the liquid outlet 230 faces the atomization area of the atomization chamber 120" and "the opening direction of the liquid inlet 210 intersects with the opening direction of the liquid outlet 230", effectively improving the use experience of the electronic cigarette.

[0046] In some embodiments, the electronic cigarette further includes a first seal 400; the first seal 400 is installed on the side of the valve body 200 close to the liquid outlet 230, and the first seal 400 is arranged along the circumference of the liquid outlet 230. In this way, when the valve body 200 rotates to the second rotation position, while the liquid outlet 230 is in sealing contact with a part of the inner wall of the atomization chamber 120, the connection between the outer circumference of the liquid outlet 230 and a part of the inner wall of the atomization chamber 120 is sealed by the first seal 400, thereby further improving the sealing effect on the liquid outlet 230.

[0047] Further, the first seal 400 includes, but is not limited to, a silicone rubber seal ring, a rubber seal ring, etc.

[0048] In some embodiments, the electronic cigarette further includes a reset member 500; both ends of the reset member 500 are respectively connected to the housing 100 and the rotation driving member 300, and are used to drive the valve body 200 to reset from the first rotation position to the second rotation position through the rotation driving member 300. In this way, on the one hand, the reset member 500 is used to realize the automatic reset of the valve body 200, so as to ensure that the liquid outlet 230 is in a sealed state when the electronic cigarette is not in use, thereby effectively preventing the e-liquid in the oil chamber 110 from leaking and being polluted by air.

[0049] Further, the reset member 500 is an elastic member. Understandably, when an external force is applied to make the rotation driving member drive the valve body 200 to rotate to the first rotation position, the elastic member is compressed to form energy storage; when no external force is applied to the rotation driving member 300 anymore, the energy storage of the elastic member is used to drive the valve body 200 to reset through the rotation driving member 300, so as to realize the automatic reset of the valve body 200 when the electronic cigarette is not in use.

[0050] Furthermore, the elastic member includes, but is not limited to, a spring, a torsion spring, etc.

[0051] In some embodiments, a receiving cavity 310 is formed by enclosing the outer wall of the housing 100 on one side of the rotation driving member 300 close to the housing 100; the reset member 500 is disposed in the receiving cavity 310. In this way, the reset member 500 is protected by the receiving cavity 310 to avoid wear and damage to the reset member 500, thereby improving the use stability of the reset function of the reset member 500 for the rotation driving member 300.

[0052] In some embodiments, the housing 100 is provided with a first limiting portion 130, and the first limiting portion 130 is used to limit the position of the valve body 200 when it rotates to the first rotation position. In this way, the accuracy of the valve body 200 when it rotates to the first rotation position is ensured through the first limiting portion 130, so as to ensure that the liquid outlet 230 can be completely opened and communicated with the atomization cavity 120, and further ensure the flow efficiency and atomization efficiency of the e-liquid.

[0053] In some embodiments, the housing 100 is provided with a second limiting portion 140, and the second limiting portion 140 is used to limit the position of the valve body 200 when it rotates to the second rotation position. In this way, the accuracy of the valve body 200 when it rotates to the second rotation position is ensured through the first limiting portion 130, so as to ensure that the liquid outlet 230 can form a sealed abutment with the inner wall of the atomization cavity 120, and further ensure the sealing performance of the liquid outlet 230.

[0054] Further, the first limiting portion 130 and / or the second limiting portion 140 may be disposed within the accommodation cavity 310. On the one hand, it can prevent the first limiting portion 130 and / or the second limiting portion 140 from being worn and damaged by the outside world. On the other hand, it can improve the space utilization rate within the accommodation cavity 310, making the overall structure of the electronic cigarette more compact.

[0055] Furthermore, a resisting portion (not shown in the figure) is provided on the side of the rotary driving member 300 close to the housing 100; when the housing 100 is provided with the first limiting portion 130, the resisting portion (not shown in the figure) is used to cooperate and abut against the first limiting portion 130 when the valve body 200 rotates to the first rotation position, thereby restricting the position of the valve body 200 when it rotates to the first rotation position; when the housing 100 is provided with the second limiting portion 140, the resisting portion (not shown in the figure) is used to cooperate and abut against the second limiting portion 140 when the valve body 200 rotates to the second rotation position, thereby restricting the position of the valve body 200 when it rotates to the second rotation position.

[0056] In some embodiments, the rotary driving member 300 is rotatably disposed on the housing 100, and a rotary shaft 320 is formed at one end of the rotary driving member 300 close to the housing 100; the rotary shaft 320 passes through the housing 100 along the direction of the rotary driving member 300 close to the housing 100 and extends into the atomization cavity 120 to be fixedly connected to the valve body 200. [[ID=,7]]

[0057] In this embodiment, by disposing the rotary driving member 300 on the housing 100, it is convenient for the user to operate the rotary driving member 300 to control the rotation of the valve body 200 between the first rotation position and the second rotation position.

[0058] Secondly, on the one hand, the rotary shaft 320 serves as the rotation center of the rotary driving member 300 for the rotary driving member 300 to rotate around the rotary shaft 320; on the other hand, the rotary shaft 320 serves as a component for connecting and transmitting with the valve body 200, so that when the rotary driving member 300 is subjected to an external force, the valve body 200 rotates together with the rotary driving member 300. In this way, the utilization rate of the rotary shaft 320 is effectively improved, and the compactness of the overall structure of the electronic cigarette is further improved.

[0059] In some embodiments, the electronic cigarette further includes a second sealing member 600; the second sealing member 600 is sleeved on the rotary shaft 320 and is located between the rotary shaft 320 and the housing 100. In this way, the connection between the rotary shaft 320 and the housing 100 is sealed by the second sealing member 600, thereby preventing the e-liquid from leaking from the connection between the rotary shaft 320 and the housing 100, and further improving the sealing effect on the liquid outlet 230.

[0060] Further, the second seal 600 includes, but is not limited to, a silica gel sealing ring, a rubber sealing ring, etc.

[0061] In some embodiments, a screwing portion 330 protrudes from a side of the rotary driving member 300 away from the housing 100. In this way, the screwing portion 330 provides a force application point for the user to improve the screwing accuracy and convenience when the user screws the rotary driving member 300.

[0062] In some embodiments, the electronic cigarette further includes a liquid storage container 700 detachably installed in the housing 100, and the oil cavity 110 is formed in the liquid storage container 700. In this way, it is possible to replace the liquid storage container 700 after it is used up, improving the convenience of using the electronic cigarette.

[0063] Further, the detachable connection between the liquid storage container 700 and the housing 100 includes, but is not limited to, threaded connection, snap connection, plug connection, mortise and tenon connection, etc.

[0064] Further, the liquid storage container 700 is an oil storage bottle.

[0065] In some embodiments, the electronic cigarette further includes an atomizer 800 disposed in the housing 100, and the atomization cavity 120 is formed in the atomizer 800.

[0066] Understandably, the atomizer 800 includes an atomization core, so that when the electronic cigarette is used, the e-liquid in the atomization area in the atomization cavity 120 is atomized by the atomization core.
