[0035] The present application proposes an electronic cigarette, which may include a shell and a valve device. An oil storage chamber and an oil supply chamber are formed inside the shell. The valve device includes a valve assembly and a push assembly that are connected to each other. The valve assembly is arranged in the shell, and the valve assembly is connected to the oil storage chamber and the oil supply chamber. A first channel and a second channel are formed in the valve assembly; the push assembly is passed through the shell; and the valve device can move along the axial direction of the valve assembly. The valve device has a first position and a second position. In the first position, the oil supply chamber, the first channel and the oil storage chamber are connected in sequence, and the oil storage chamber, the second channel and the oil supply chamber are connected in sequence. In the second position, the first channel and the second channel are not connected to the oil storage chamber, or the first channel and the second channel are not connected to the oil supply chamber.

[0036] In the electronic cigarette of the present application, the valve device can move between a first position and a second position along the axial direction of the valve assembly. In the first position, the oil supply chamber, the first channel and the oil storage chamber are connected in sequence, and the oil storage chamber, the second channel and the oil supply chamber are connected in sequence; thus, the smoke oil in the oil supply chamber can flow into the oil storage chamber via the first channel, and the gas in the oil storage chamber can be discharged into the oil supply chamber via the second channel. The air pressure of the oil supply chamber and the oil storage chamber is balanced, so that the oil supply chamber can quickly fill the oil storage chamber with oil, and the effect of filling the oil is relatively good. In the second position, the first channel and the second channel are not connected to the oil storage chamber, or the first channel and the second channel are not connected to the oil supply chamber; thus, the sealing between the oil storage chamber and the oil supply chamber is good, and the smoke oil and gas will not flow freely between the oil supply chamber and the oil storage chamber, and the electronic cigarette is not prone to oil leakage. In summary, through the above-mentioned settings, the electronic cigarette of the present application has a good oil filling effect and is not prone to oil leakage.

[0037] The following will mainly describe the specific structure of the electronic cigarette.

[0038] See also Figure 1 and Figure 2The electronic cigarette 10 of the present application includes a housing 100. An oil storage chamber 110 and an oil supply chamber 120 are formed inside the housing 100. A large amount of smoke oil is stored inside the oil supply chamber 120, and the oil supply chamber 120 is connected to the oil storage chamber 110, and the oil supply chamber 120 can fill the oil storage chamber 110 with oil.

[0039] The electronic cigarette 10 of the present application includes an atomizer assembly (not shown), which is disposed in the oil storage chamber 110. The atomizer assembly can absorb the oil in the oil storage chamber 110 and atomize the absorbed oil into aerosol, which is then inhaled by the user through a mouthpiece (not shown).

[0040] See also Figure 1 and Figure 2 The housing 100 may include a first sub-shell 130, a second sub-shell 140 and a third sub-shell 150 connected in sequence, the oil storage chamber 110 is formed in the first sub-shell 130, and the oil supply chamber 120 is formed in the third sub-shell 150. In other words, the oil supply chamber 120 and the oil storage chamber 110 are arranged at intervals. Of course, the oil supply chamber 120 and the oil storage chamber 110 can also be arranged adjacent to each other.

[0041] See also Figure 1 and Figure 2 The electronic cigarette 10 of the present application includes a first sealing member 400. The first sealing member 400 is disposed in the housing 100 (specifically, the first sub-shell 130), and the first sealing member 400 is provided with an oil inlet channel 410 connected to the oil storage chamber 110. Specifically, a first opening is provided at one end of the first sub-shell 130 connected to the second sub-shell 140, and the first sealing member 400 covers the first opening, and the first sub-shell 130 and the first sealing member 400 together form the oil storage chamber 110.

[0042] See also Figure 1 and Figure 2 The electronic cigarette 10 of the present application includes a second sealing member 500. The second sealing member 500 is disposed in the housing 100 (specifically, the third sub-shell 150), and the second sealing member 500 is provided with an oil supply channel 510 connected to the oil supply chamber 120. Specifically, a second opening is provided at one end of the third sub-shell 150 connected to the second sub-shell 140, and the second sealing member 500 covers the second opening, and the third sub-shell 150 and the second sealing member 500 jointly form the oil supply chamber 120.

[0043] See also Figures 1 to 4 The electronic cigarette 10 of the present application includes a valve device 200. The valve device 200 includes a valve component 210 and a push component 220 connected to each other. The valve component 210 and the push component 220 can be clamped, bonded or screwed.

[0044] See also Figure 1 and Figure 2The valve assembly 210 is disposed in the housing 100, and the valve assembly 210 communicates with the oil storage chamber 110 and the oil supply chamber 120. Figure 1 and Figure 2 The two ends of the valve assembly 210 are arranged in the oil inlet channel 410 and the oil supply channel 510, so that the valve assembly 210 can communicate with the oil storage chamber 110 and the oil supply chamber 120. A first channel and a second channel are formed in the valve assembly 210. The first channel can be mainly used for guiding oil, and the second channel can be mainly used for guiding gas.

[0045] See also Figure 1 and Figure 2 The pushing component 220 is disposed through the housing 100. The pushing component 220 and the housing 100 can be slidably connected.

[0046] See also Figure 1 and Figure 2 , the valve device 200 can move along the axial direction of the valve assembly 210. Specifically, under the drive of external force (which can be manual), the push assembly 220 can slide along the axial direction of the valve assembly 210 on the housing 100, and the push assembly 220 drives the valve assembly 210 to move.

[0047] See also Figure 1 and Figure 2 , the valve device 200 has a first position and a second position. Figure 1 , the valve device 200 is in the first position, the oil supply chamber 120, the first channel and the oil storage chamber 110 are connected in sequence, and the oil storage chamber 110, the second channel and the oil supply chamber 120 are connected in sequence. As a result, the smoke oil in the oil supply chamber 120 can flow into the oil storage chamber 110 through the first channel, and the gas in the oil storage chamber 110 can be discharged into the oil supply chamber 120 through the second channel. The gas pressure of the oil supply chamber 120 and the oil storage chamber 110 is balanced, so that the oil supply chamber 120 can quickly inject oil into the oil storage chamber 110, and the injection effect is relatively good. Please refer to Figure 2 , the valve device 200 is in the second position, the first channel and the second channel are not connected to the oil storage chamber 110, or the first channel and the second channel are not connected to the oil supply chamber 120. Therefore, the sealing between the oil storage chamber 110 and the oil supply chamber 120 is good, the smoke oil and gas will not flow freely between the oil supply chamber 120 and the oil storage chamber 110, and the electronic cigarette 10 is not prone to oil leakage.

[0048] See also Figures 1 to 4 The valve assembly 210 includes a first conduit 211, a second conduit 212 and a blocking member 213. One end of the first conduit 211 is disposed in the oil supply channel 510, and the other end of the first conduit 211 is disposed in the oil inlet channel 410. Thus, the first conduit 211 can guide the oil, that is, the smoke oil in the oil supply chamber 120 can flow into the oil storage chamber 110 through the first conduit 211.

[0049] See also Figure 1 and Figure 2 The other end of the first conduit 211 is inserted into one end of the oil inlet passage 410 and connected to the plugging member 213. The plugging member 213 is at least partially located in the oil storage chamber 110. The plugging member 213 can be used to open or seal the oil inlet passage 410.

[0050] See also Figure 1 and Figure 2 , the second conduit 212 is sleeved in the first conduit 211 at intervals, and one end of the second conduit 212 close to the oil supply channel 510 extends to the bottom of the oil supply chamber 120. Therefore, in the process of the oil supply chamber 120 supplying oil to the oil storage chamber 110, the flow of the smoke oil causes the air pressure of the oil storage chamber 110 to increase and the air pressure of the oil supply chamber 120 to decrease, and the gas in the oil storage chamber 110 flows toward the oil supply chamber 120 spontaneously through the second conduit 212, and one end of the second conduit 212 extending into the oil supply chamber 120 leaks out from the smoke oil and contacts with the gas in the oil supply chamber 120, so that the gas in the air guide tube can be quickly discharged into the oil supply chamber 120, thereby the air pressure of the oil storage chamber 110 and the air pressure of the oil supply chamber 120 are relatively balanced, and the smoke oil in the oil supply chamber 120 can maintain a relatively fast speed to flow to the oil storage chamber 110.

[0051] See also Figure 1 In the first position, the blocking member 213 is spaced from the oil inlet channel 410, and the first conduit 211 and the second conduit 212 are both connected to the oil inlet channel 410. Thus, the oil supply chamber 120 can guide oil to the oil storage chamber 110, and the oil storage chamber 110 can exhaust air to the oil supply chamber 120. Figure 2 In the second position, the blocking member 213 is sealed with the oil inlet channel 410, and the first conduit 211 and the second conduit 212 are not connected with the oil storage chamber 110. Therefore, the sealing between the oil supply chamber 120 and the oil storage chamber 110 is relatively good, and the electronic cigarette 10 is not easy to leak oil.

[0052] See also Figure 3 and Figure 4 A first notch 214 is provided at one end of the first conduit 211 connected to the blocking member 213, and a second notch 215 is provided at one end of the second conduit 212 close to the oil inlet channel 410. Thus, the first conduit 211 and the second conduit 212 can both be connected to the oil inlet channel 410. The number of the first notch 214 and the second notch 215 can both be multiple, thereby achieving a better connection effect. Multiple first notches 214 can be arranged along the circumference of the first conduit 211, and multiple second notches 215 can be arranged along the circumference of the second conduit 212. The provision of the first notch 214 and the second notch 215 allows the smoke oil and air to flow through the first conduit 211 and the second conduit 212 more smoothly.

[0053] See also Figure 1In one embodiment, both ends of the second conduit 212 can be free ends. As a result, the second conduit 212 can move freely in the first conduit 211 to adapt to the flow of the e-liquid and / or the position change of the electronic cigarette 10 (the second conduit 212 is limited by the wall of the oil supply chamber 120 and the first conduit 211 and will not leave the first conduit 211). In another embodiment, the end of the second conduit 212 close to the oil inlet channel 410 is connected to the blocking member 213. As a result, the connection effect of the second conduit 212 is better.

[0054] See also Figures 1 to 4 The sealing member 213 has a sealing portion 216 protruding toward the oil supply channel 510 on one side thereof facing the oil inlet channel 410, and a matching portion 411 is formed on the wall of the oil supply channel 510 corresponding to the sealing portion 216. As a result, the contact area between the sealing member 213 and the wall of the oil supply channel 510 is relatively large, and the sealing member 213 has a relatively good sealing connection effect on the oil supply channel 510.

[0055] See also Figures 1 to 4 The push assembly 220 includes a sleeve 221, a connector 222 and a push plate 223 connected in sequence. The sleeve 221 is sleeved with the valve assembly 210, the connector 222 is inserted into the housing 100, and the push plate 223 is slidably connected with the outer wall of the housing 100. The sleeve 221 and the connector 222 can be integrally formed, or they can be detachably connected (clamped, bonded or screwed). The connector 222 and the push plate 223 can be integrally formed, or they can be detachably connected (clamped, bonded or screwed). The sleeve 221 and the valve assembly 210 can be abutted, clamped, bonded or screwed.

[0056] See also Figures 1 to 3 , the sleeve 221 can be sleeved outside the first conduit 211. Thus, the effect of the push component 220 driving the valve component 210 to move is better.

[0057] See also Figures 1 to 4 The connecting member 222 includes an insert sleeve member 224 and a socket member 225. The sleeve 221, the insert sleeve member 224, the socket member 225 and the push plate 223 are connected in sequence. The socket member 225 forms a ring-shaped slot 226 corresponding to the insert sleeve member 224. Thus, the insert sleeve member 224 and the socket member 225 are plugged together, and the connection effect of the two is better, and then the connection effect of the push assembly 220 and the valve assembly 210 is better.

[0058] The plug-in sub-component 224 and the socket sub-component 225 can be further connected by snapping (such as Figure 4 as shown), bonding or screwing.

[0059] See also Figure 4The slot wall of the slot 226 is provided with a strip-shaped notch 227, which is provided at the notch of the slot 226 and extends toward the slot bottom of the slot 226. The provision of the strip-shaped notch 227 enables the slot wall of the slot 226 to be deformed when being squeezed by the insert sleeve sub-component 224, thereby reducing the difficulty of plugging the insert sleeve sub-component 224 with the socket sub-component 225. There can be a plurality of strip-shaped notches 227, and the plurality of strip-shaped notches 227 can be arranged along the circumference of the socket sub-component 225.

[0060] See also Figure 3 and Figure 4 The side of the push plate 223 facing away from the connecting member 222 may be provided with an anti-slip structure, thereby increasing friction, and the external force has a better driving effect on the movement of the valve device 200.

[0061] The outer wall of the housing 100 (specifically, the second sub-housing 140) may be formed with a slide groove corresponding to the push plate 223. The slide groove guides and limits the sliding of the push plate 223, and the sliding effect of the push plate 223 is better, and the overall structure of the electronic cigarette 10 is more compact.

[0062] See also Figure 3 and Figure 4 The push assembly 220 further includes a stopper 228, one end of which is connected to the sleeve 221, and the other end of which is slidably connected to the inner wall of the housing 100. The stopper 228 may be columnar. The stopper 228 can limit and guide the movement of the valve assembly 210, thereby making the movement of the valve assembly 210 more stable.

[0063] See also Figure 1 and Figure 2 The electronic cigarette 10 of the present application further includes a limiting assembly 300. The limiting assembly 300 is disposed in the housing 100, and includes a limiting cylinder 310 and a guide column 320. One end of the limiting cylinder 310 is connected to the housing 100, and the other end of the limiting cylinder 310 faces the valve assembly 210. One end of the guide column 320 is connected to the valve assembly 210, and the other end of the guide column 320 is sleeved in the limiting cylinder 310 and slidably connected to the limiting cylinder 310. The limiting assembly 300 can limit and guide the movement of the valve assembly 210, so that the movement effect of the valve assembly 210 is better.

[0064] The limiting cylinder 310 and the housing 100 may be integrally formed or detachably connected (by snapping, bonding or screwing). Figure 1 and Figure 2 The inner wall of the housing 100 is provided with a connecting cylinder 170, and the limiting cylinder 310 is sleeved in the connecting cylinder 170. As a result, the connection of the limiting cylinder 310 in the housing 100 is more stable, so that the limiting assembly 300 has a better limiting and guiding effect on the valve assembly 210.

[0065] See also Figure 1 and Figure 2 The limiting assembly 300 further includes a stopper 330, one end of which is connected to the end of the limiting cylinder 310 away from the housing 100, and the other end of the stopper 330 faces the inside of the limiting cylinder 310. The longitudinal section of the guide column 320 is in a T-shape, a Y-shape, or an inverted L-shape, and the stopper 330 is used to prevent the guide column 320 from leaving the limiting cylinder 310. Therefore, the guide column 320 will not leave the limiting cylinder 310, so that the limiting assembly 300 can achieve the effect of limiting and guiding the movement of the valve assembly 210.

[0066] See also Figure 1 and Figure 2 The limit assembly 300 further includes an elastic member 340, which is sleeved between the limit cylinder 310 and the guide column 320. One end of the elastic member 340 extends out of the limit cylinder 310 and is connected to the valve assembly 210 (specifically, the blocking member 213), and the elastic member 340 is in a compressed state. Thus, the elastic member 340 can assist the blocking member 213 in sealing the oil inlet channel 410, and prevent the blocking member 213 from unexpectedly moving and opening the oil inlet channel 410. The elastic member 340 and the valve assembly 210 can be welded, bonded, or clamped.

[0067] See also Figures 1 to 4 The valve assembly 210 (specifically, the blocking member 213) is formed with a first connection groove 217 and a second connection groove 218 on one side facing the limiting assembly 300. The first connection groove 217 is annular and sleeved outside the second connection groove 218. One end of the elastic member 340 is inserted into the first connection groove 217, and one end of the guide column 320 is inserted into the second connection groove 218. Therefore, the connection effect between the elastic member 340 and the valve assembly 210 is relatively good, and the connection effect between the guide column 320 and the valve assembly 210 is relatively good, so that the limiting assembly 300 has a relatively good effect of limiting and guiding the valve assembly 210.

[0068] See also Figure 1 and Figure 2 The electronic cigarette 10 further includes an electric control device 160. The electric control device 160 is disposed in the second sub-shell 140, and the electric control device 160 (specifically, a battery of the electric control device 160) is slidably connected to the side of the valve assembly 210 away from the push assembly 220. Thus, the electric control device 160 can guide and limit the movement of the valve assembly 210, the movement of the valve assembly 210 is better, and the overall structure of the electronic cigarette 10 is more compact.

[0069] In the electronic cigarette 10 of the present application, by arranging the electric control device 160 between the oil storage chamber 110 and the oil supply chamber 120, sufficient installation space can be provided for the valve device 200 to facilitate its function, and the overall structure of the electronic cigarette 10 is also more compact.

[0070] See also Figure 1 In the electronic cigarette 10 of the present application, when the valve device 200 is pushed to the first position, the oil storage chamber 110 can be filled with oil by inverting the electronic cigarette 10. Figure 2 When the valve device 200 moves from the first position to the second position, the oil storage chamber 110 stops filling with oil.

[0071] The above description is only a preferred embodiment of the present application, and does not limit the patent scope of the present application. All equivalent structural changes made by using the contents of the present application specification and drawings under the inventive concept of the present application, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present application.
