[0034] The present application will be described in detail below in combination with the drawings and specific embodiments.

[0035] Please refer to Figures 1 to 11The utility model provides a kind of electronic cigarette, it includes cartridge 1, preparatory oil cup 2 and battery assembly 3, cartridge 1 and preparatory oil cup 2 are arranged side by side and contact each other, and the end face of cartridge 1 towards battery assembly 3 is provided with first docking groove 101 and second docking groove 102, first docking groove 101 and second docking groove 102 are all along the longitudinal extension of electronic cigarette setting, i.e.

[0036] Specifically, cartridge 1 includes first oil storage component 11, first check valve 12 and atomizing core 13, first oil storage component 11 includes oil storage tube 111, air tube 112, sealing seat 113 and connecting cover 114, first oil storage cavity 1111 is formed in oil storage tube 111, and first oil storage cavity 1111 is used to store first tobacco tar. First tobacco tar can include propylene glycol, glycerol and flavoring materials. It can be understood that as long as it can be atomized to form smoke, the chemical composition of first tobacco tar is not specifically limited here.

[0037] Oil injection hole 1112, air vent hole 1113 and first oil guide hole 1114 are provided at the cavity wall of first oil storage cavity 1111. Air tube 112 is located in oil storage tube 111, the first end of air tube 112 is connected with oil storage tube 111, the second end of air tube 112 is connected with sealing seat 113, and the side wall of air tube 112 is provided with oil outlet hole 1121 communicated with first oil storage cavity 1111.

[0038] Sealing seat 113 is inserted into one end of oil storage tube 111 and extends into connecting cover 114 to prevent first tobacco tar from leaking, and sealing seat 113 can be made of silica gel or rubber. The end face of sealing seat 113 facing battery assembly 3 is provided with first fixing groove 1131 and second fixing groove 1132. Connecting cover 114 is covered on the end face of one end of oil storage tube 111 and connected with oil storage tube 111, and connecting cover 114 is provided with first docking hole 1141 and second docking hole 1142, first docking hole 1141 corresponds to the position of second fixing groove 1132, and first docking hole 1141 and first fixing groove 1131 constitute first docking groove 101. Second docking hole 1142 corresponds to the position of second fixing groove 1132, and second docking hole 1142 and second fixing groove 1132 constitute second docking groove 102.

[0039] The first oil storage component 11 further comprises an elastic sealing sheet 15 and a third fixing ring 16. The elastic sealing sheet 15 is located in the first oil storage cavity 1111 and covers the hole opening of the oil injection hole 1112 facing the first oil storage cavity 1111. The elastic sealing sheet 15 is provided with a relief cut for the insertion of an oil injection device into the first oil storage cavity 1111 during oil injection. The third fixing ring 16 is fixed in the first oil storage cavity 1111 and abuts against the elastic sealing sheet 15 to prevent the elastic sealing sheet 15 from falling off.

[0040] During production, the first tobacco tar can be injected into the first oil storage cavity 1111 through the oil injection hole 1112 and the relief cut of the elastic sealing sheet 15. After the oil injection is completed, the first tobacco tar is blocked by the elastic sealing sheet 15, thus avoiding leakage. By providing the exhaust hole 1113, the air pressure in the first oil storage cavity 1111 during oil injection is avoided from being too high, thus reducing the probability of leakage of the first tobacco tar from the air passage 112. Preferably, the cross-sectional area of the exhaust hole 1113 is smaller than that of the oil injection hole 1112, thus reducing the probability of leakage during use.

[0041] The first oil storage component 11 further comprises an elastic sealing plug 17 and a suction nozzle 18. The elastic sealing plug 17 is located in the suction nozzle 18 and covers the hole opening of the oil injection hole 1112 away from the first oil storage cavity 1111 and the hole opening of the exhaust hole 1113 away from the first oil storage cavity 1111, thus better sealing the oil storage tube 111. The suction nozzle 18 is connected to the oil storage tube 111 and communicates with the air passage 112, and a user smokes tobacco tar through the suction nozzle 18. The first one-way valve 12 is installed at the first oil guide hole 1114 and is used to guide the second tobacco tar of the standby oil cup 2 into the first oil storage cavity 1111 and prevent the first tobacco tar from flowing towards the standby oil cup 2.

[0042] The first one-way valve 12 comprises a first fixing ring 121 and a first elastic valve body 122. The first fixing ring 121 is installed at the first oil guide hole 1114 and is a metal ring, thus being firmly fixed. The first elastic valve body 122 is installed in the first fixing ring 121 and is provided with a first valve for preventing the first tobacco tar from flowing out. The first elastic valve body 122 can be a silica gel valve body or a rubber valve body, etc. Through the cooperation of the first fixing ring 121 and the first elastic valve body 122, not only is the connection firm, but also oil leakage is better avoided.

[0043] The atomizing core 13 is located in the first oil storage cavity 1111 and is used for atomizing the first tobacco tar. The atomizing core 13 comprises a porous elastic foam oil blocking pipe 131, a fixed pipe 132, a porous oil guiding sheet 133 and an electric heating element 134. The porous elastic foam oil blocking pipe 131 is located in the air pipe 112 and is sleeved outside the fixed pipe 132. The porous elastic foam oil blocking pipe 131 can be a polyurethane foam pipe and the like, and the material thereof is not limited as long as it is made of a porous material with elasticity, which can better seal the oil outlet hole 1121. The outer wall of the porous elastic foam oil blocking pipe 131 covers the oil outlet hole 1121 to block the first tobacco tar at the oil outlet hole 1121 from excessively flowing into the fixed pipe 132. The bottom end of the fixed pipe 132 is connected with the sealing seat 13, and the side wall of the fixed pipe 132 is provided with a flow guiding hole 1321.

[0044] The porous oil guiding sheet 133 is at least partially located in the fixed pipe 132 and is used for adsorbing the first tobacco tar at the flow guiding hole 1321. The porous oil guiding sheet 133 is spaced apart from the porous elastic foam oil blocking pipe 131. The electric heating element 134 is in contact with the porous oil guiding sheet 133 and is used for atomizing the first tobacco tar at the porous oil guiding sheet 133. The porous oil guiding sheet 133 can be made of a fiber material and the like and can be wound into a tubular structure. The electric heating element 134 can be an electric heating wire or an electric heating net and the like.

[0045] Since the porous elastic foam oil blocking pipe 131 is sleeved outside the fixed pipe 132, the outer wall of the porous elastic foam oil blocking pipe 131 covers the oil outlet hole 1121 to block the first tobacco tar at the oil outlet hole 1121 from excessively flowing into the fixed pipe 132, and the porous oil guiding sheet 133 is spaced apart from the porous elastic foam oil blocking pipe 131, the porous elastic foam oil blocking pipe 131 itself can play a certain buffering role on the flow of the first tobacco tar, thereby reducing the flowability of the first tobacco tar and slowing down the speed of the first tobacco tar flowing into the porous oil guiding sheet 133.

[0046] Secondly, the porous elastic foam oil blocking pipe 131 itself is distributed with a plurality of micropore structures. When the first tobacco tar passes through the micropore structures, an oil film is formed at the micropore structures. The surface tension of the oil film can further reduce the flowability of the first tobacco tar, thereby further slowing down the speed of the first tobacco tar flowing into the porous oil guiding sheet 133, so that the problem of “flying oil” of the atomizing core 13 caused by the first tobacco tar flowing too fast can be effectively reduced during the user's smoking process. It can be understood that as long as the first tobacco tar can be atomized, the structure of the atomizing core 13 is not limited.

[0047] The third butt joint groove 201 is arranged at one end face of the oil cup 2 and extends in the transverse direction of the electronic cigarette, and the first buckling protrusion 202 is arranged in the third butt joint groove 201.

[0048] Specifically, the second oil storage component 21 comprises a containing shell 211, a first sealing cover 212 and a second sealing cover 213. The containing shell 211 is provided with the second oil storage cavity 203 and the oil guide cavity 204. The second oil storage cavity 203 is in communication with the first end face of the containing shell 211, and the oil guide cavity 204 is in communication with the second end face of the containing shell 211. The first end face of the containing shell 211 is arranged opposite to the second end face of the containing shell 211. The first sealing cover 212 is arranged at the cavity opening of the second oil storage cavity 203, and the third butt joint groove 201 is arranged at the end face of the first sealing cover 212. The second sealing cover 213 is arranged at the cavity opening of the oil guide cavity 204 and is used for sealing the oil guide cavity to prevent the second tobacco tar from leaking from the cavity opening of the oil guide cavity 204.

[0049] The cavity wall of the oil guide cavity 204 is provided with a second oil guide hole 2041, a third oil guide hole 2042, a limiting step 2043 and a second connecting groove 2044. The second oil guide hole 2041 is in position correspondence with the first oil guide hole 1114 and is in communication with the oil guide cavity 204. The third oil guide hole 2042 is in communication with the oil guide cavity 204 and the second oil storage cavity 203. The second connecting groove 2044 is located at the bottom of the oil guide cavity 204.

[0050] The oil supply switch 22 is arranged in the oil guide cavity 204. The electronic cigarette of the utility model comprises a normal state and an inverted state. In the normal state, the oil supply switch 22 covers the hole opening of the second oil guide hole 2041. The height of the position where the third oil guide hole 2042 is located is higher than the height of the position where the second oil guide hole 2041 is located. Therefore, in the normal state, the second tobacco tar in the second oil storage cavity 203 is prevented from flowing into the first oil storage cavity 1111. In the inverted state, the oil supply switch 22 is removed from covering the hole opening of the second oil guide hole 2041 due to the action of gravity. The second tobacco tar in the second oil storage cavity 203 can flow into the first oil storage cavity 1111 through the third oil guide hole 2042, the second oil guide hole 2041 and the first oil guide hole 1114. Therefore, the user does not need to perform the pushing and pulling or pressing operation, and the user is facilitated to use.

[0051] Preferably, the oil guiding cavity 204 is located in the second oil storage cavity 203 or arranged side by side with the second oil storage cavity 203, so that the second tobacco tar can flow into the oil guiding cavity 204 by gravity as much as possible, and then flow into the first oil storage cavity 1111 quickly.

[0052] The oil supply switch 22 comprises a piston 221 and a driving member 222. The piston 221 is movably arranged in the oil guiding cavity 204 and can move along the oil guiding cavity 204. An end surface of the piston 221 is provided with a first connecting groove 2211. In the upright state, the limiting step 2043 abuts against the piston 221, and at this time, the piston 221 corresponds to the position of the second oil guiding hole 2041, and the side surface of the piston 221 covers the hole of the second oil guiding hole 2041. By arranging the limiting step 2043 to abut against the piston 221, the second oil guiding hole 2041 can be prevented from being opened due to vibration.

[0053] During the conversion of the piston 221 from the inverted state to the upright state, the piston 221 moves towards the second sealing cover 213 due to the gravity. That is, in the inverted state, the piston 221 removes the covering of the hole of the second oil guiding hole 2041 due to the gravity, and at this time, the tobacco tar in the oil guiding cavity 204 can flow into the first oil storage cavity 1111 through the second oil guiding hole 2041 and the first oil guiding hole 1114.

[0054] The driving member 222 is used to drive the piston 221 to reset during the conversion of the piston 221 from the inverted state to the upright state, so as to avoid the problem that the piston 221 cannot be reset due to the friction or the floating force or the viscous force of the tobacco tar. In the embodiment, the driving member 222 is a spring. A first end of the spring is inserted into the first connecting groove 2211 to be connected with the piston 221. A second end of the spring is inserted into the second connecting groove 2044 to be connected with the oil guiding cavity 204. The connection mode of the spring facilitates assembly and improves production efficiency. In another embodiment, the driving member 222 comprises a first magnet and a second magnet. The first magnet is arranged at the second sealing cover, and the second magnet is arranged at the piston 221. The first magnet and the second magnet repel each other. In the inverted state, the gravity of the second magnet and the piston 221 is greater than the repulsive force between the first magnet and the second magnet.

[0055] The second one-way valve 23 is inserted into one end of the second oil guide hole 2041, and includes a second fixed ring 231 and a second elastic valve body 232. The second elastic valve body 232 is installed at the second oil guide hole 2041, the second fixed ring 231 is a metal ring, and the second elastic valve body 232 is mostly inserted into the first fixed ring 121. One end of the second elastic valve body 232 is in elastic abutment with one end of the first fixed ring 121, and the second elastic valve body 232 is provided with a second valve for preventing the first tobacco tar from flowing into the reserve oil cup 2. Specifically, the longitudinal section of the second elastic valve body 232 is T-shaped, and the outer circumferential surface of the second elastic valve body 232 is provided with an annular limiting groove 2321, and the first fixed ring 121 is located in the limiting groove 2321. Thus, the connection is reliable and the assembly is facilitated.

[0056] In use, when the first tobacco tar is consumed, the electronic cigarette is inverted, the piston 221 moves towards the second sealing cover 213 due to gravity, and the second oil guide hole 2041 is opened. Thus, the second tobacco tar in the second oil storage cavity 203 flows into the oil guide cavity 204 through the third oil guide hole 2042, and flows into the first oil storage cavity 1111 through the second one-way valve 23 in the second oil guide hole 2041 and the first one-way valve 12 in the first oil guide hole 1114, thereby achieving the replenishment of tobacco tar.

[0057] The battery assembly 3 includes a mounting shell 31, a bracket 32, a battery 33, a controller 34, a first electrode 35, and a second electrode 36. The side wall of the mounting shell 31 is provided with an air inlet hole 311, and the bracket 32 is connected to the mounting shell 31 in a plug-in manner. The bracket 32 is provided with a butt joint rib 321 extending into the third butt joint groove 201. The butt joint rib 321 extends along the transverse direction of the electronic cigarette. The butt joint rib 321 is provided with a second buckling protrusion 322, which is buckled and connected to the first buckling protrusion 202. Thus, the connection is stable, and during assembly, the butt joint rib 321 is aligned with the third butt joint groove 201, and then the two are spliced together, thereby facilitating assembly. The battery 33 is located in the mounting shell 31 and is electrically connected to the controller 34. The controller 34 is located in the mounting shell 31 and is electrically connected to the first electrode 35 and the second electrode 36.

[0058] The controller 34 is configured to control the battery 33 to supply power to the atomizing core 13, so that the atomizing core 13 atomizes the first tobacco tar to form smoke for a user to smoke. The first electrode 35 is connected to the support 32 and extends into the first abutting groove 101 through the first abutting hole 1141, and the second electrode 36 is connected to the support 32 and extends into the second abutting groove 102 through the second abutting hole 1142. The first electrode 35 and the second electrode 36 are both electrically connected to the atomizing core 13 and are configured to transmit electric energy. The first electrode 35 is electrically connected to the first end of the electric heating element 134, and the second electrode 36 is electrically connected to the second end of the electric heating element 134. Since the first electrode 35 and the second electrode 36 are configured to not only achieve the function of electrical connection but also achieve the function of mechanical connection, the connection structure is simplified, the production process is reduced, and the production efficiency is improved.

[0059] The battery assembly 3 further comprises a sealing block 37 provided with a gas passing hole 38 in communication with the cartridge 1. The surface of the support 32 facing the cartridge 1 is provided with a first gas guiding groove 323 in communication with the gas passing hole 38 and the outer surface of the electronic cigarette. The sealing block 37 is arranged at the opening of the first gas guiding groove 323. This structure is not only convenient to manufacture and reduces the production process, but also effectively avoids air leakage.

[0060] The battery assembly 3 further comprises a gas adjusting member 38. The side surface of the support 32 is provided with a second gas guiding groove 324 corresponding to the position of the air inlet hole 311. The air inlet hole 311 is in communication with the second gas guiding groove 324, and the second gas guiding groove 324 is in communication with the first gas guiding groove 323 and the outer surface of the electronic cigarette. When a user smokes the smoke, external air flows into the atomizing core 13 through the second gas guiding groove 324 and the first gas guiding groove 323 from the air inlet hole 311. The gas adjusting member 38 is movably arranged at the opening of the second gas guiding groove 324 and is configured to adjust the air intake, so that it can be adapted to users with different lung capacities.

[0061] Through the cooperation between the standby oil cup 2 and the cartridge 1, when the first tobacco tar in the first oil storage cavity 1111 is consumed, the second tobacco tar in the second oil storage cavity 203 is guided into the first oil storage cavity 1111 by opening the oil supply switch 22 in an inverted manner to supplement the tobacco tar. Therefore, the amount of the overall stored tobacco tar is large, and the cartridge 1 needs not to be frequently replaced, which is not only convenient for users to use but also more environmentally friendly. Since the cartridge 1 and the standby oil cup 2 are both connected to the battery assembly 3 in a non-threaded connection manner, the assembly is convenient and the production efficiency is high, which is also convenient for users to use. In addition, since the cartridge 1 and the standby oil cup 2 are arranged side by side and in contact with each other, the structure is reliable and is not easy to be detached by external force.

[0062] Since the cartridge 1 and the reserve oil cup 2 are arranged side by side and are detachably connected with the battery assembly, when the tobacco tar in the reserve oil cup 2 is consumed, the new reserve oil cup 2 can be conveniently replaced. Finally, the end face of the first one-way valve 12 abuts against the end face of the second one-way valve 23, so that the reserve oil cup 2 is not only conveniently detached, but also the tobacco tar leakage is better avoided.

[0063] In summary, the utility model is through the ingenious cooperation of the cartridge 1 and the reserve oil cup 2, the cartridge 1 is provided with the first oil guide hole 1114. The reserve oil cup 2 includes a second oil storage part 21 and an oil supply switch 22, the second oil storage part 21 is provided with a second oil storage cavity 203 and an oil guide cavity 204, the second oil storage cavity 203 is used for storing the second tobacco tar; the cavity wall of the oil guide cavity 204 is provided with a second oil guide hole 2041 and a third oil guide hole 2042, the second oil guide hole 2041 corresponds to the position of the first oil guide hole 1114 and communicates with the oil guide cavity 204, the third oil guide hole 2042 communicates with the oil guide cavity 204 and the second oil storage cavity 203.
