[0034] The utility model will be explained in detail below in combination with the drawings and specific embodiments.

[0035] Please refer to Figures 1 to 10 The utility model provides a kind of electronic cigarette, it includes cartridge 1, reserve oil cup 2 and battery component 3, cartridge 1 and reserve oil cup 2 are arranged side by side and contact each other, and the end face of cartridge 1 facing battery component 3 is provided with first docking groove 101 and second docking groove 102, first docking groove 101 and second docking groove 102 are all arranged along the longitudinal direction of electronic cigarette, i.e. both are arranged along the longitudinal direction of cartridge 1.The distance between first docking groove 101 and second docking groove 102 is pre-set, and its distance can be set to 1 centimeter to 2 centimeters etc. according to need.Because cartridge 1 and reserve oil cup 2 are arranged side by side and contact each other, they are barriers to each other, increase the reliability of structure, and not easy to fall off when external force acts.

[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 pipe 111, air pipe 112, sealing seat 113 and connecting cover 114, first oil storage cavity 1111 is formed in oil storage pipe 111, and first oil storage cavity 1111 is used to store first tobacco tar.First tobacco tar can include propylene glycol, glycerol and essence and spice etc. material.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 and exhaust hole 1113 are arranged at the cavity wall of first oil storage cavity 1111.Air pipe 112 is located in oil storage pipe 111, the first end of air pipe 112 is connected with oil storage pipe 111, the second end of air pipe 112 is connected with sealing seat 113, and the side wall of air pipe 112 is provided with oil outlet hole 1121 communicated with first oil storage cavity 1111.

[0038] The sealing seat 113 is inserted into one end of the oil storage tube 111 and extends into the connecting cover 114 to prevent the first tobacco tar from leaking. The sealing seat 113 can be made of silica gel or rubber. The end surface of the sealing seat 113 facing the battery assembly 3 is provided with a first fixing groove 1131 and a second fixing groove 1132. The connecting cover 114 is arranged at the end surface of one end of the oil storage tube 111 and connected to the oil storage tube 111.

The second butt joint hole 1142 and the second fixing groove 1132 form the second butt joint groove 102.

[0039] The first oil storage component 11 further includes 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 inserting 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, thereby preventing leakage. By providing the exhaust hole 1113, the air pressure in the first oil storage cavity 1111 during oil injection is prevented from being too high, thereby reducing the probability of leakage of the first tobacco tar from the air tube 112. Preferably, the cross-sectional area of the exhaust hole 1113 is smaller than the cross-sectional area of the oil injection hole 1112, thereby reducing the probability of leakage during use.

[0041] The first oil storage component 11 further includes an elastic sealing plug 17 and a suction nozzle 18. The elastic sealing plug 17 is located in the suction nozzle 18. The elastic sealing plug 17 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, thereby better sealing the oil storage tube 111. The suction nozzle 18 is connected to the oil storage tube 111 and communicates with the air tube 112. A user smokes through the suction nozzle 18. The first one-way valve 12 is installed at the cavity wall of the first oil storage cavity 1111 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 fixed ring 121 and a first elastic valve body 122, the first fixed ring 121 is installed at the cavity wall of the first oil storage cavity 111, and the first fixed ring 121 is a metal ring, thus being fixed stably. The first elastic valve body 122 is installed in the first fixed ring 121, and the first elastic valve body 122 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.

[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 the porous material with elasticity is used, and the porous elastic foam oil blocking pipe 131 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, so as to block the first tobacco tar at the oil outlet hole 1121 from flowing into the fixed pipe 132 excessively. 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 located at least partially in the fixed pipe 132 and is used for adsorbing the tobacco tar at the flow guiding hole 1321, and the porous oil guiding sheet 133 is spaced 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 tobacco tar at the porous oil guiding sheet 133. The porous oil guiding sheet 133 can be made of fiber 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, and the outer wall of the porous elastic foam oil blocking pipe 131 covers the oil outlet hole 1121, so as to block the first tobacco tar at the oil outlet hole 1121 from flowing into the fixed pipe 132 excessively, and the porous oil guiding sheet 133 is spaced from the porous elastic foam oil blocking pipe 131, thus the porous elastic foam oil blocking pipe 131 itself can buffer the flow of the first tobacco tar to some extent, so as to reduce the flowability of the tobacco tar and slow down the speed of the first tobacco tar flowing into the porous oil guiding sheet 133.

[0046] Secondly, the porous elastic foam oil blocking tube 131 itself is provided with a plurality of microporous structures. When the tobacco tar passes through the microporous structures, an oil film is formed at the microporous structures. The surface tension of the oil film can further reduce the flowability of the tobacco tar, so that the speed of the first tobacco tar flowing into the porous oil guide sheet 133 is further slowed down, thereby effectively reducing the problem of "oil flying" of the atomizing core 13 caused by the tobacco tar flowing in too fast during the user's smoking. It can be understood that as long as the first tobacco tar can be atomized, the structure of the atomizing core 13 is not specifically limited.

[0047] The end face of the preparation oil cup 2 is provided with a third docking groove 201 extending in the transverse direction of the electronic cigarette. The first buckling protrusion 202 is arranged in the third docking groove 201. Specifically, the preparation oil cup 2 includes a second oil storage component 21, a pump oil component 22, and a second one-way valve 23. The second oil storage component 21 is provided with a second oil storage cavity 203 and an oil guide cavity 204. The second oil storage cavity 203 is used to store the second tobacco tar. The chemical composition of the second tobacco tar can be the same as or different from that of the first tobacco tar, which is not specifically limited here.

[0048] The oil guide cavity 204 is in communication with the first oil storage cavity 1111 and the second oil storage cavity 203. The pump oil component 22 is at least partially inserted into the oil guide cavity 204 and is used to pump the second tobacco tar in the second oil storage cavity 203 into the first oil storage cavity 1111 through the second one-way valve 22 and the first one-way valve 12. Preferably, the oil guide cavity 204 is located in the second oil storage cavity 203 or is arranged side by side with the second oil storage cavity 203, so that the second tobacco tar can automatically flow into the oil guide cavity 204 by gravity as much as possible, and then the second tobacco tar can be quickly pumped into the first oil storage cavity 1111.

[0049] Specifically, the second oil storage component 21 includes a containing shell 211, a sealing cover 212, and a limiting ring 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 sealing cover 212 is arranged at the cavity opening of the second oil storage cavity 203, and the end face of the sealing cover 212 is provided with the third docking groove 201. The limiting ring 213 is inserted at the cavity opening of the oil guide cavity 204 and is used to prevent the pump oil component 22 from falling off from the oil guide cavity 204.

[0050] The cavity wall of the oil guiding cavity 204 is provided with an oil inlet hole 2041 and an oil outlet hole 2042. The oil inlet hole 2041 is communicated with the second oil storage cavity 203, and the oil outlet hole 2042 is used to discharge the second tobacco tar from the second oil storage cavity 203 into the first oil storage cavity 1111. When the electronic cigarette is vertically placed with the suction nozzle upward, the position of the oil outlet hole 2042 is lower than the top wall of the second oil storage cavity 203, thus facilitating the discharge of the second tobacco tar into the first oil storage cavity 1111.

[0051] In addition, the cavity wall of the oil guiding cavity 204 is further provided with a gas guiding hole 2043 communicated with the second oil storage cavity 203. The first one-way valve 12 is located outside the oil preparation cup 2 and communicated with the oil outlet hole 2042, and is used to prevent the oil in the first oil storage cavity 1111 from flowing into the oil outlet hole 2042. Since the first one-way valve 12 is located outside the oil preparation cup 2, the tobacco cartridge 1 and the oil preparation cup 2 can be separately detached from the battery assembly 3, so that the tobacco cartridge 1 and the oil preparation cup 2 can be arbitrarily replaced, which is not only convenient for maintenance, but also convenient for use.

[0052] The oil pumping component 22 comprises a piston 221, a connecting rod 222, an elastic member 223, an oil blocking ball 224 and an oil blocking ring 225. The piston 221 is abutted with the limiting ring 213 and movably connected with the oil guiding cavity 204. One end of the piston 221 is connected with a button 226, and the piston 221 can be formed by one or more parts. Preferably, the outer circumferential surface of the piston 221 is provided with a sealing ring tightly matched with the oil guiding cavity 204. The first end of the connecting rod 222 is a closed end, the first end of the connecting rod 222 is abutted with the piston 221, and the second end of the connecting rod 222 is abutted with the first end of the elastic member 223. The second end of the elastic member 223 is abutted with the cavity wall of the oil guiding cavity 204, and the elastic member 223 can be a spring or a spring piece. The oil blocking ball 224 is located at the hole of the oil inlet hole 2041. The oil blocking ring 225 is sleeved on the connecting rod 222 and connected with the cavity wall of the second oil storage cavity 203, and the oil guiding gap is formed between the oil blocking ring 225 and the connecting rod 222. The hole of the oil outlet hole 2042 facing away from the first oil storage cavity 1111 is located between the piston 221 and the oil blocking ring 225, and the oil outlet hole 2042 is communicated with the oil inlet hole 2041 through the oil guiding gap.

[0053] The end surface of the connecting rod 222 is provided with a flow dividing groove 2221 extending along the axial direction of the connecting rod 222, the flow dividing groove 2221 is communicated with the oil inlet hole 2041, the side wall of the flow dividing groove 2221 is provided with a flow dividing hole 2222 communicated with the oil guiding gap. The outer circumferential surface of the connecting rod 222 is provided with an annular oil pushing part 2223 located on the side of the oil blocking ring 225 facing away from the piston 221. The end surface of the connecting rod 222 facing away from the piston 221 is provided with an annular limiting part 2224 sleeved on one end of the elastic member 223, so that the elastic member 223 is positioned more reliably.

[0054] The electronic cigarette comprises a first state and a second state, in the first state, the piston 221 covers the air guide hole 2043 and faces away from the orifice of the second oil storage cavity 203, in the second state, the piston 221 is spaced from the air guide hole 2043, the air guide hole 2043 is communicated with the outside of the electronic cigarette through the oil guide cavity 204, and thus the second tobacco tar can flow into the oil guide cavity 204 more easily.

[0055] The second one-way valve 23 is inserted into one end of the oil discharge hole 2042, and comprises a second fixed ring 231 and a second elastic valve body 232, the second elastic valve body 232 is installed at the side wall of the second oil storage part 21, the second fixed ring 231 is a metal ring, 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, which is used for preventing the first tobacco tar from flowing into the preparatory oil cup 2. Specifically, the longitudinal section of the second elastic valve body 232 is T-shaped, 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, so that the connection is reliable and assembly is facilitated.

[0056] In the use process, when the first tobacco tar is consumed, the user presses the button 226, the elastic member 223 is compressed, the piston 221 and the connecting rod 222 move together in the direction of the oil blocking ball 224, at the same time, the gas in the oil guide cavity 204 flows into the second oil storage cavity 203 through the oil inlet hole 2041, because the density of the gas is smaller than that of the second tobacco tar, the gas flows to the top wall of the second oil storage cavity 203 after flowing into the second oil storage cavity 203. When the piston 221 is spaced from the air guide hole 2043, the electronic cigarette enters the second state, the air guide hole 2043 is communicated with the outside of the electronic cigarette through the oil guide cavity 204, and the gas in the second oil storage cavity 203 can flow out from the air guide hole 2043, so that the user is more labor-saving when pressing the button 226, and it is more beneficial for the second tobacco tar to flow into the oil guide cavity 204.

[0057] When the user stops pressing the button 226, under the elastic restoring force of the elastic member 223, the connecting rod 222 and the piston 221 move towards the direction away from the oil blocking ball 224, at this time, the lower end of the oil guide cavity 204 stores the area of negative pressure state of air, therefore, the second tobacco tar in the second oil storage cavity 203 flows into the oil guide cavity 204 through the oil inlet hole 2041. The oil pushing part 2223 pushes the second tobacco tar in the oil guide cavity 204 out of the oil guide gap and flows into the first oil storage cavity 1111 through the oil outlet hole 2042 and the first one-way valve 12, thereby realizing the replenishment of tobacco tar. Through the cooperation of the flow distribution groove 2221 and the flow distribution hole 2222, the second tobacco tar flowing out of the oil inlet hole 2041 flows to the oil outlet hole 2042 through the flow distribution groove 2221 and the flow distribution hole 2222 quickly. By setting the oil pushing part 2223, the movement of the fluid in the oil guide cavity 204 is better driven.

[0058] The battery assembly 3 comprises a mounting shell 31, a support 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. The support 32 is connected to the mounting shell 31 in a plug-in manner. The support 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. The second buckling protrusion 322 is connected to the first buckling protrusion 202 in a buckling manner. Therefore, not only is the connection stable, but also when assembling, the butt joint rib 321 is only 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.

[0059] The controller 34 is used 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 the user to smoke. The first electrode 35 is connected to the support 32 and extends into the first butt joint groove 101 through the first butt joint hole 1141. The second electrode 36 is connected to the support 32 and extends into the second butt joint groove 102 through the second butt joint hole 1142. The first electrode 35 and the second electrode 36 are both electrically connected to the atomizing core 13 for transmitting electric energy. Among them, 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 not only used to realize the function of electrical connection, but also used to realize the function of mechanical connection, the connection structure is simplified, the production process is reduced, and the production efficiency is improved.

[0060] The battery assembly 3 further comprises a sealing block 37 provided with an air passing hole 38 in communication with the cartridge 1. The surface of the support 32 facing the cartridge 1 is provided with a first air guide groove 323 in communication with the air passing hole 38 and the outer surface of the electronic cigarette. The sealing block 37 is arranged at the groove opening of the first air guide groove 323. This structure is convenient for manufacturing and reduces the production process, and air leakage is avoided.

[0061] The battery assembly 3 further comprises an air adjusting member 38. The side surface of the support 32 is provided with a second air guide groove 324 corresponding to the position of the air inlet hole 311. The air inlet hole 311 is in communication with the second air guide groove 324. The second air guide groove 324 is in communication with the first air guide groove 323 and the outer surface of the electronic cigarette. When a user smokes, external air flows into the atomizing core 13 through the air inlet hole 311, the second air guide groove 324 and the first air guide groove 323. The air adjusting member 38 is movably arranged at the groove opening of the second air guide groove 324, and is used for adjusting the air inlet amount, so as to adapt to users with different lung capacities.

[0062] Through the cooperation between the standby oil cup 2 and the cartridge 1, when the first tobacco oil in the first oil storage cavity 1111 is consumed, the second tobacco oil in the second oil storage cavity 203 is pumped into the first oil storage cavity 1111 by the oil pumping member 22 to supplement the tobacco oil. Therefore, the amount of the overall stored tobacco oil is large, and the cartridge 1 is not replaced frequently, which is convenient for users to use and more environmentally friendly. Since the cartridge 1 and the standby oil cup 2 are both connected with the battery assembly 3 in a non-threaded connection manner, assembly is convenient, production efficiency is high, and users are also convenient 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.

[0063] In summary, the electronic cigarette comprises the cartridge 1 and the standby oil cup 2 cooperating with each other. The cartridge 1 comprises a first oil storage member 11 and a first one-way valve 12. The first oil storage member 11 is provided with a first oil storage cavity 111. The first one-way valve 12 is mounted at the cavity wall of the first oil storage cavity 111. The standby oil cup 2 comprises a second oil storage member 21 and a second one-way valve 23. The second oil storage member 21 is provided with a second oil storage cavity 203. The second one-way valve 23 is connected with the second oil storage member 21 and is in communication with the second oil storage cavity 203. One end surface of the first one-way valve 12 abuts against one end surface of the second one-way valve 23. Therefore, when the tobacco oil in the cartridge 1 is consumed, the tobacco oil in the second oil storage cavity 203 can be supplemented into the first oil storage cavity 111 through the second one-way valve 23 and the first one-way valve 12. Therefore, the user does not need to carry a portable oil storage bottle when going out, which is convenient for the user to add oil and carry. When the tobacco oil is supplemented, oil leakage due to inaccurate positioning is also avoided.

[0064] In addition, 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, a new reserve oil cup 2 can be conveniently replaced. Finally, since one end face of the first one-way valve 12 abuts against one end face of the second one-way valve 23, not only is the reserve oil cup 2 conveniently detachable, but tobacco tar leakage is also effectively avoided.
