Description

TECHNICAL FIELD

[0002] A large-capacity electronic cigarette generally comprises an oil supply cavity capable of storing a large amount of tobacco tar, thereby being capable of continuously supplying oil to the oil storage cavity. The atomization assembly adsorbs the tobacco tar in the oil storage cavity and atomizes the tobacco tar through the energy supply of the power supply assembly. The aerosol flows out through the suction nozzle communicating with the atomization cavity for the user to smoke. However, the design of the existing electronic cigarette is not reasonable. In the process of oil injection from the oil supply cavity to the oil storage cavity, the gas in the oil storage cavity pressed by the tobacco tar is difficult to be discharged in time, resulting in slow oil injection speed and even stopping of oil injection.

In summary, through the above settings, the electronic cigarette of the present application has good oil injection effect and is not prone to oil leakage.

[0036] The specific structure of the electronic cigarette will be mainly described below.

[0037] Please refer to Figure 1 and Figure 2The electronic cigarette 10 comprises a housing 100. The housing 100 is internally formed with an oil storage cavity 110 and an oil supply cavity 120. The oil supply cavity 120 internally stores a large amount of tobacco tar, and the oil supply cavity 120 is communicated with the oil storage cavity 110, so that the oil supply cavity 120 can inject oil into the oil storage cavity 110. The electronic cigarette 10 comprises an atomization assembly (not shown), which is arranged in the oil storage cavity 110 and can adsorb the tobacco tar in the oil storage cavity 110 and atomize the adsorbed tobacco tar into aerosol, which is further inhaled by a user through a cigarette holder (not shown).

[0038] Referring to Figure 1 and Figure 2 , the housing 100 can comprise a first sub-housing 130, a second sub-housing 140 and a third sub-housing 150 connected in sequence, the oil storage cavity 110 is formed in the first sub-housing 130, and the oil supply cavity 120 is formed in the third sub-housing 150. In other words, the oil supply cavity 120 and the oil storage cavity 110 are arranged in a spaced manner. Of course, the oil supply cavity 120 and the oil storage cavity 110 can also be arranged adjacent to each other.

[0039] Referring to Figure 1 and Figure 2 , the electronic cigarette 10 comprises a first sealing member 400. The first sealing member 400 is arranged in the housing 100 (specifically, the first sub-housing 130), and the first sealing member 400 is provided with an oil inlet channel 410 communicated with the oil storage cavity 110. Specifically, one end of the first sub-housing 130 connected with the second sub-housing 140 is provided with a first opening, the first sealing member 400 covers the first opening, and the first sub-housing 130 and the first sealing member 400 jointly form the oil storage cavity 110.

[0040] Referring to Figure 1 and Figure 2 , the electronic cigarette 10 comprises a second sealing member 500. The second sealing member 500 is arranged in the housing 100 (specifically, the third sub-housing 150), and the second sealing member 500 is provided with an oil supply channel 510 communicated with the oil supply cavity 120. Specifically, one end of the third sub-housing 150 connected with the second sub-housing 140 is provided with a second opening, the second sealing member 500 covers the second opening, and the third sub-housing 150 and the second sealing member 500 jointly form the oil supply cavity 120.

[0041] Referring to Figures 1 to 4 , the electronic cigarette 10 comprises a valve device 200. The valve device 200 comprises a valve assembly 210 and a pushing assembly 220 connected with each other. The valve assembly 210 and the pushing assembly 220 can be connected by clamping, bonding or screwing.

[0042] Referring to Figure 1 and Figure 2 , the valve assembly 210 is arranged in the housing 100, and the valve assembly 210 is communicated with the oil storage cavity 110 and the oil supply cavity 120. Specifically, referring toFigure 1 and Figure 2 Two ends of the valve assembly 210 are arranged in the oil inlet passage 410 and the oil supply passage 510, so that the valve assembly 210 can connect the oil storage cavity 110 and the oil supply cavity 120. The valve assembly 210 is formed with a first passage and a second passage. The first passage can be mainly used for oil guiding, and the second passage can be mainly used for gas guiding.

[0043] Referring to Figure 1 and Figure 2 The pushing assembly 220 is arranged in the shell 100. The pushing assembly 220 can be slidably connected with the shell 100.

[0044] Referring to Figure 1 and Figure 2 The valve device 200 can move along the axial direction of the valve assembly 210. Specifically, under the driving of an external force (which can be manual), the pushing assembly 220 can slide on the shell 100 along the axial direction of the valve assembly 210, and the pushing assembly 220 drives the valve assembly 210 to move.

[0045] Referring to Figure 1 and Figure 2 The valve device 200 has a first position and a second position. Referring to Figure 1 When the valve device 200 is in the first position, the oil supply cavity 120, the first passage and the oil storage cavity 110 are sequentially connected, and the oil storage cavity 110, the second passage and the oil supply cavity 120 are sequentially connected. Thus, the e-liquid in the oil supply cavity 120 can flow into the oil storage cavity 110 through the first passage, the gas in the oil storage cavity 110 can be discharged into the oil supply cavity 120 through the second passage, and the gas pressures of the oil supply cavity 120 and the oil storage cavity 110 are balanced, so that the oil injection from the oil supply cavity 120 to the oil storage cavity 110 is rapid and the effect of the oil injection is good. Referring to Figure 2 When the valve device 200 is in the second position, the first passage and the second passage are not connected with the oil storage cavity 110, or the first passage and the second passage are not connected with the oil supply cavity 120. Thus, the sealing between the oil storage cavity 110 and the oil supply cavity 120 is good, and the e-liquid and the gas cannot flow between the oil supply cavity 120 and the oil storage cavity 110 at will, and the electronic cigarette 10 is not prone to oil leakage.

[0046] Referring to 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 arranged in the oil supply passage 510, and the other end of the first conduit 211 is arranged in the oil inlet passage 410. Thus, the first conduit 211 can guide the e-liquid, that is, the e-liquid in the oil supply cavity 120 can flow into the oil storage cavity 110 through the first conduit 211.

[0047] Referring to Figure 1 and Figure 2The other end of the first conduit 211 is connected to a blocking member 213 arranged at one end of the oil inlet channel 410, and the blocking member 213 is at least partially arranged in the oil storage cavity 110. The blocking member 213 can be used to open or seal the oil inlet channel 410.

[0048] Referring to Figure 1 and Figure 2 The second conduit 212 is arranged in the first conduit 211 in a sleeved manner, and the second conduit 212 extends to the bottom of the oil supply cavity 120 near one end of the oil supply channel 510. Thus, during the process of supplying oil from the oil supply cavity 120 to the oil storage cavity 110, the flow of the tobacco tar causes the air pressure in the oil storage cavity 110 to rise and the air pressure in the oil supply cavity 120 to decrease, and the gas in the oil storage cavity 110 spontaneously flows toward the oil supply cavity 120 through the second conduit 212, and the end of the second conduit 212 extending into the oil supply cavity 120 leaks out of the tobacco tar and contacts the gas in the oil supply cavity 120, so that the gas in the gas guide conduit can be quickly discharged into the oil supply cavity 120, thereby balancing the air pressure in the oil storage cavity 110 and the air pressure in the oil supply cavity 120, and the tobacco tar in the oil supply cavity 120 can flow to the oil storage cavity 110 at a relatively fast speed.

[0049] Referring to 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 in communication with the oil inlet channel 410. Thus, oil can be supplied from the oil supply cavity 120 to the oil storage cavity 110, and air can be discharged from the oil storage cavity 110 to the oil supply cavity 120. Referring to Figure 2 In the second position, the blocking member 213 seals the oil inlet channel 410, and the first conduit 211 and the second conduit 212 are both not in communication with the oil storage cavity 110. Thus, the oil supply cavity 120 and the oil storage cavity 110 have relatively good sealing, and the electronic cigarette 10 is less likely to leak oil.

[0050] Referring to Figure 3 and Figure 4 One end of the first conduit 211 connected to the blocking member 213 is provided with a first notch 214, and one end of the second conduit 212 near the oil inlet channel 410 is provided with a second notch 215. Thus, the first conduit 211 and the second conduit 212 can both be in communication with the oil inlet channel 410. The number of the first notch 214 and the second notch 215 can both be multiple, thereby having a better communication effect. The multiple first notches 214 can be arranged along the circumference of the first conduit 211, and the multiple second notches 215 can be arranged along the circumference of the second conduit 212. The arrangement of the first notch 214 and the second notch 215 makes the flow of the tobacco tar and air through the first conduit 211 and the second conduit 212 relatively smooth.

[0051] Referring to Figure 1In an embodiment, both ends of the second conduit 212 can be free ends. In this way, the second conduit 212 can move freely in the first conduit 211 (the second conduit 212 is limited by the wall of the oil supply cavity 120 and the first conduit 211 and cannot leave the first conduit 211) in accordance with the flow of the tobacco tar and / or the position change of the electronic cigarette 10. In another embodiment, the second conduit 212 is connected to the stopper 213 at an end close to the oil inlet channel 410. In this way, the connection of the second conduit 212 is better.

[0052] Referring to Figures 1 to 4 , the side of the stopper 213 facing the oil inlet channel 410 is formed with a sealing portion 216 protruding towards the oil supply channel 510, and the wall of the oil supply channel 510 is formed with a matching portion 411 corresponding to the sealing portion 216. In this way, the contact area of the stopper 213 and the wall of the oil supply channel 510 is large, and the stopper 213 has a better sealing and connecting effect on the oil supply channel 510.

[0053] Referring to Figures 1 to 4 , the pushing assembly 220 includes a sleeve 221, a connecting piece 222, and a push plate 223 connected in sequence, the sleeve 221 is sleeved with the valve assembly 210, the connecting piece 222 is arranged in the shell 100, and the push plate 223 is slidingly connected with the outer wall of the shell 100. The sleeve 221 and the connecting piece 222 can be integrally formed or detachably connected (clamped, bonded, or screwed). The connecting piece 222 and the push plate 223 can be integrally formed or detachably connected (clamped, bonded, or screwed). The sleeve 221 and the valve assembly 210 can be abutted, clamped, bonded, or screwed.

[0054] Referring to Figures 1 to 3 , the sleeve 221 can be sleeved outside the first conduit 211. In this way, the pushing assembly 220 has a better effect of moving the valve assembly 210.

[0055] Referring to Figures 1 to 4 , the connecting piece 222 includes a plug-in sleeve sub-piece 224 and a plug-in socket sub-piece 225, and the sleeve 221, the plug-in sleeve sub-piece 224, the plug-in socket sub-piece 225, and the push plate 223 are connected in sequence. The plug-in socket sub-piece 225 is formed with a ring-shaped plug-in slot 226 corresponding to the plug-in sleeve sub-piece 224. In this way, the plug-in sleeve sub-piece 224 and the plug-in socket sub-piece 225 are plugged in, and the connection of the two is better, and thus the connection of the pushing assembly 220 and the valve assembly 210 is better.

[0056] The plug-in sleeve sub-piece 224 and the plug-in socket sub-piece 225 can be further clamped (as shown in Figure 4 ), bonded, or screwed.

[0057] Referring to Figure 4The slot wall of the slot 226 is provided with a strip-shaped gap 227, which is arranged at the slot opening of the slot 226 and extends towards the slot bottom. The arrangement of the strip-shaped gap 227 enables the slot wall of the slot 226 to deform when being pressed by the plug-in subassembly 224, thereby reducing the difficulty of plugging the plug-in subassembly 224 and the socket subassembly 225. The number of the strip-shaped gaps 227 can be multiple, and the multiple strip-shaped gaps 227 can be arranged along the circumference of the socket subassembly 225.

[0058] Please refer to Figure 3 and Figure 4 The side of the push plate 223 away from the connecting member 222 can be provided with an anti-skid structure, thereby increasing the friction and having a better driving effect of the external force on the movement of the valve device 200.

[0059] The outer wall of the shell 100 (specifically, the second sub-shell 140) can be formed with a sliding groove corresponding to the push plate 223. The sliding groove plays a guiding and limiting role for the sliding of the push plate 223, the sliding effect of the push plate 223 is better, and the overall structure of the electronic cigarette 10 is also more compact.

[0060] Please refer to Figure 3 and Figure 4 The push assembly 220 further includes a limiting member 228, one end of the limiting member 228 is connected to the sleeve 221, and the other end of the limiting member 228 is in sliding connection with the inner wall of the shell 100. The limiting member 228 can be in a columnar shape. The limiting member 228 can limit and guide the movement of the valve assembly 210, thereby making the movement of the valve assembly 210 more stable.

[0061] Please refer to Figure 1 and Figure 2 The electronic cigarette 10 of the present application further includes a limiting assembly 300. The limiting assembly 300 is arranged in the shell 100, and includes a limiting cylinder 310 and a guide column 320. One end of the limiting cylinder 310 is connected to the shell 100, and the other end of the limiting cylinder 310 is directed towards 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 in sliding connection with the limiting cylinder 310. The limiting assembly 300 can limit and guide the movement of the valve assembly 210, thereby making the movement of the valve assembly 210 better.

[0062] The limiting cylinder 310 and the shell 100 can be integrally formed or detachably connected (clamped, bonded or screwed). Please refer to Figure 1 and Figure 2 The inner wall of the shell 100 is provided with a connecting cylinder 170, and the limiting cylinder 310 is sleeved in the connecting cylinder 170. In this way, the connection of the limiting cylinder 310 in the shell 100 is more stable, thereby making the limiting and guiding effects of the limiting assembly 300 on the valve assembly 210 better.

[0063] Please refer to Figure 1 and Figure 2 The limiting assembly 300 further comprises a stopper 330, one end of the stopper 330 is connected to the end of the limiting cylinder 310 away from the shell 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 the shape of T, Y or inverted L, and the stopper 330 is used to prevent the guide column 320 from leaving the limiting cylinder 310. In this way, the guide column 320 cannot 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.

[0064] Please refer to Figure 1 and Figure 2 The limiting assembly 300 further comprises a spring 340, which is sleeved between the limiting cylinder 310 and the guide column 320. One end of the spring 340 extends out of the limiting cylinder 310 and is connected to the valve assembly 210 (specifically, the sealing member 213), and the spring 340 is in a compressed state.
