[0031] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0032] Please seeFigures 1 to 8 The utility model provides an electronic cigarette, it includes atomization subassembly 1, liquid supply subassembly 2 and power supply subassembly 3, atomization subassembly 1 and liquid supply subassembly 2 are arranged side by side and contact each other, and the end face of atomization subassembly 1 facing power supply subassembly 3 is provided with first docking groove 101 and second docking groove 102, first docking groove 101 and second docking groove 102 all are along the longitudinal extension of electronic cigarette setting, that is, both are along the longitudinal extension of atomization subassembly 1 setting. First docking groove 101 and second docking groove 102 are spaced apart by a predetermined distance, and the distance therebetween can be set to between 1 cm and 2 cm as needed. Since atomization subassembly 1 and liquid supply subassembly 2 are arranged side by side and contact each other, they serve as barriers to each other, increasing the reliability of the structure, and are not easily detached when an external force is applied.

[0033] Specifically, atomization subassembly 1 includes a first liquid storage component 11, a one-way valve 12, and an atomization core 13. The first liquid storage component 11 includes a liquid storage tube 111, a vent tube 112, a sealing seat 113, and a connecting cover 114. The liquid storage tube 111 has a first liquid storage cavity 1111 formed therein, and the first liquid storage cavity 1111 is used to store a first atomization liquid. The first atomization liquid can include propylene glycol, glycerol, and flavoring materials. It should be understood that as long as the liquid can be atomized to form smoke, the chemical composition of the first atomization liquid is not specifically limited herein.

[0034] The first liquid storage cavity 1111 has a liquid injection hole 1112 and an exhaust hole 1113 disposed at the cavity wall. The vent tube 112 is located within the liquid storage tube 111, with a first end of the vent tube 112 connected to the liquid storage tube 111 and a second end of the vent tube 112 connected to the sealing seat 113. The side wall of the vent tube 112 is provided with a liquid outlet hole 1121 that communicates with the first liquid storage cavity 1111.

[0035] The sealing seat 113 is inserted into one end of the liquid storage tube 111 and extends into the connecting cover 114 to prevent leakage of the first atomization liquid. The sealing seat 113 can be made of materials such as silicone or rubber. The end face of the sealing seat 113 facing the power supply subassembly 3 is provided with a first fixing groove 1131 and a second fixing groove 1132. The connecting cover 114 is arranged on the end face of the liquid storage tube 111 and is connected to the liquid storage tube 111. The connecting cover 114 is provided with a first docking hole 1141 and a second docking hole 1142. The first docking hole 1141 corresponds in position to the second fixing groove 1132, and the first docking hole 1141 and the first fixing groove 1131 form the first docking groove 101. The second docking hole 1142 corresponds in position to the second fixing groove 1132, and the second docking hole 1142 and the second fixing groove 1132 form the second docking groove 102.

[0036] The first liquid storage component 11 further comprises an elastic sealing sheet 15 and a fixing ring 16. The elastic sealing sheet 15 is located in the first liquid storage cavity 1111 and covers the hole of the liquid injection hole 1112 facing the first liquid storage cavity 1111. The elastic sealing sheet 15 is provided with a cutout for inserting the liquid injection equipment into the first liquid storage cavity 1111 during liquid injection. The fixing ring 16 is fixed in the first liquid storage cavity 1111 and abuts against the elastic sealing sheet 15 to prevent the elastic sealing sheet 15 from falling off.

[0037] During production, the first atomized liquid can be injected into the first liquid storage cavity 1111 through the liquid injection hole 1112 and the cutout of the elastic sealing sheet 15. After the liquid injection is completed, the first atomized liquid is blocked by the elastic sealing sheet 15, thereby avoiding leakage. By providing the exhaust hole 1113, the air pressure in the first liquid storage cavity 1111 during liquid injection is prevented from being too high, thereby reducing the probability of leakage of the first atomized liquid from the air passage 112. Preferably, the cross-sectional area of the exhaust hole 1113 is smaller than that of the liquid injection hole 1112, thereby reducing the probability of leakage during use.

[0038] The first liquid 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 of the liquid injection hole 1112 away from the first liquid storage cavity 1111 and the hole of the exhaust hole 1113 away from the first liquid storage cavity 1111, thereby better sealing the liquid storage tube 111. The suction nozzle 18 is connected to the liquid storage tube 111 and communicates with the air passage 112, and a user sucks the smoke through the suction nozzle 18. The one-way valve 12 is installed at the cavity wall of the first liquid storage cavity 1111 for guiding the second atomized liquid of the liquid supply assembly 2 into the first liquid storage cavity 1111 and preventing the first atomized liquid from flowing towards the liquid supply assembly 2.

[0039] The atomizing core 13 is located in the first liquid storage cavity 1111 for atomizing the first atomized liquid. The atomizing core 13 comprises a porous elastic foam liquid blocking tube 131, a fixing tube 132, a porous liquid guiding sheet 133, and an electric heating element 134. The porous elastic foam liquid blocking tube 131 is located in the air passage 112 and is sleeved outside the fixing tube 132. The porous elastic foam liquid blocking tube 131 can be a polyurethane foam tube, and the material thereof is not limited as long as it is made of a porous material with elasticity, which can better seal the liquid outlet hole 1121. The outer wall of the porous elastic foam liquid blocking tube 131 covers the liquid outlet hole 1121 to prevent the atomized liquid at the liquid outlet hole 1121 from excessively flowing into the fixing tube 132. The bottom end of the fixing tube 132 is connected to the sealing seat 13, and the side wall of the fixing tube 132 is provided with a liquid guiding hole 1321.

[0040] The porous liquid guide sheet 133 is at least partially located in the fixed tube 132 and is used to absorb the atomized liquid at the liquid guide hole 1321, and the porous liquid guide sheet 133 is spaced apart from the porous elastic foam liquid blocking tube 131. The electric heating element 134 is in contact with the porous liquid guide sheet 133 and is used to atomize the atomized liquid at the porous liquid guide sheet 133. The porous liquid guide sheet 133 can be made of fiber or 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 or the like.

[0041] Since the porous elastic foam liquid blocking tube 131 is sleeved outside the fixed tube 132, and the outer wall of the porous elastic foam liquid blocking tube 131 covers the liquid outlet hole 1121 to block the first atomized liquid at the liquid outlet hole 1121 from flowing into the fixed tube 132 excessively, and the porous liquid guide sheet 133 is spaced apart from the porous elastic foam liquid blocking tube 131, the porous elastic foam liquid blocking tube 131 itself can play a certain buffering role on the flow of the first atomized liquid, thereby reducing the flowability of the atomized liquid and slowing down the speed of the first atomized liquid flowing into the porous liquid guide sheet 133.

[0042] Secondly, the porous elastic foam liquid blocking tube 131 itself is distributed with a plurality of micropore structures, and when the atomized liquid passes through the micropore structures, an oil film is formed at the micropore structures, and the surface tension generated by the oil film can further reduce the flowability of the atomized liquid, so that the speed of the first atomized liquid flowing into the porous liquid guide sheet 133 is further slowed down, thereby effectively reducing the problem of "flying liquid" of the atomized core 13 caused by the atomized liquid flowing in too fast during the user's suction use. It can be understood that as long as the first atomized liquid can be atomized, the structure of the atomized core 13 is not limited.

[0043] The end face of the liquid supply assembly 2 is provided with a third butt joint groove 201 extending along the transverse direction of the electronic cigarette, and the third butt joint groove 201 is provided with a first buckling protrusion 202. Specifically, the liquid supply assembly 2 comprises a second liquid storage component 21 and a pump liquid component 22, the second liquid storage component 21 is provided with a second liquid storage cavity 203 and a liquid guide cavity 204, the second liquid storage cavity 203 is used for storing a second atomized liquid, and the chemical composition of the second atomized liquid can be the same as or different from that of the first atomized liquid, which is not limited here.

[0044] The liquid guide cavity 204 is in communication with the first liquid storage cavity 1111 and the second liquid storage cavity 203. The pump liquid component 22 is at least partially inserted into the liquid guide cavity 204 and is used for pumping the second atomized liquid in the second liquid storage cavity 203 into the first liquid storage cavity 1111. Preferably, the liquid guide cavity 204 is located in the second liquid storage cavity 203 or the liquid guide cavity 204 and the second liquid storage cavity 203 are arranged side by side, so that the second atomized liquid can flow into the liquid guide cavity 204 automatically by gravity as much as possible, and then the second atomized liquid can be quickly pumped into the first liquid storage cavity 1111.

[0045] Specifically, the second liquid storage component 21 comprises a containing shell 211, a sealing cover 212 and a limiting ring 213. The containing shell 211 is provided with the second liquid storage cavity 203 and the liquid guide cavity 204. The second liquid storage cavity 203 is in communication with the first end face of the containing shell 211, and the liquid 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 liquid storage cavity 203, and the end face of the sealing cover 212 is provided with the third abutting groove 201. The limiting ring 213 is inserted at the cavity opening of the liquid guide cavity 204, and is used to prevent the pump liquid component 22 from falling off from the liquid guide cavity 204.

[0046] The cavity wall of the liquid guide cavity 204 is provided with a liquid inlet hole 2041 and a liquid outlet hole 2042. The liquid inlet hole 2041 is in communication with the second liquid storage cavity 203, and the liquid outlet hole 2042 is used to discharge the second atomized liquid flowing from the second liquid storage cavity 203 into the liquid guide cavity 204 into the first liquid storage cavity 1111. When the electronic cigarette is vertically placed with the suction nozzle upward, the height of the position where the liquid outlet hole 2042 is located is lower than the top wall of the second liquid storage cavity 203, thereby facilitating the discharge of the second atomized liquid into the first liquid storage cavity 1111.

[0047] In addition, the cavity wall of the liquid guide cavity 204 is further provided with a gas guide hole 2043 in communication with the second liquid storage cavity 203. The one-way valve 12 extends into the liquid outlet hole 2042, is in communication with the liquid outlet hole 2042, and is used to prevent the liquid in the first liquid storage cavity 1111 from flowing into the liquid outlet hole 2042. Since the one-way valve 12 extends into the liquid outlet hole 2042, the up-and-down movement of the liquid supply assembly 2 can be prevented, the liquid supply assembly 2 can be prevented from falling off due to vibration, and the reliability of the structure is improved.

[0048] The pump liquid component 22 comprises a piston 221, a connecting rod 222, an elastic member 223, a liquid blocking ball 224 and a liquid blocking ring 225. The limiting ring 213 abuts against the piston 221. The piston 221 is movably connected with the liquid guide cavity 204. One end of the piston 221 is connected with a button 226. 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 which is tightly matched with the liquid guide cavity 204. The first end of the connecting rod 222 is a closed end. The first end of the connecting rod 222 abuts against the piston 221. The second end of the connecting rod 222 abuts against the first end of the elastic member 223. The second end of the elastic member 223 abuts against the cavity wall of the liquid guide cavity 204. The elastic member 223 can be a spring or a spring piece. The liquid blocking ball 224 is located at the hole opening of the liquid inlet hole 2041. The liquid blocking ring 225 is sleeved on the connecting rod 222 and is connected with the cavity wall of the second liquid storage cavity 203. A liquid guide gap is formed between the liquid blocking ring 225 and the connecting rod 222. The hole opening of the liquid outlet hole 2042 which faces away from the first liquid storage cavity 1111 is located between the piston 221 and the liquid blocking ring 225. The liquid outlet hole 2042 is in communication with the liquid inlet hole 2041 through the liquid guide gap.

[0049] The end surface of the connecting rod 222 is provided with a flow distribution groove 2221 extending along the axial direction of the connecting rod 222, the flow distribution groove 2221 is communicated with the liquid inlet hole 2041, the side wall of the flow distribution groove 2221 is provided with a flow distribution hole 2222, the flow distribution hole 2222 is communicated with the liquid guide gap. The outer peripheral surface of the connecting rod 222 is provided with an annular liquid pushing part 2223, the liquid pushing part 2223 is located on the side of the liquid blocking ring 225 away from the piston 221. The end surface of the connecting rod 222 away from the piston 221 is provided with an annular limiting part 2224, the limiting part 2224 is sleeved on one end of the elastic member 223, so that the elastic member 223 is positioned more reliably.

[0050] The electronic cigarette of the utility model includes first state and second state, when the first state, the piston 221 covers the air inlet hole 2043 away from the hole of the second liquid storage cavity 203, when the second state, the piston 221 is spaced apart from the air inlet hole 2043, the air inlet hole 2043 is communicated with the outside of the electronic cigarette through the liquid guide cavity 204, so that the second atomized liquid can flow into the liquid guide cavity 204 more easily.

[0051] In the use process, when the first atomized liquid is exhausted, the user presses the button 226, then the elastic member 223 is compressed, the piston 221 and the connecting rod 222 move together to the direction of the liquid blocking ball 224, at the same time, the gas in the liquid guide cavity 204 flows into the second liquid storage cavity 203 through the liquid inlet hole 2041, because the density of the gas is less than the density of the second atomized liquid, so the gas flows to the top wall of the second liquid storage cavity 203 after flowing into the second liquid storage cavity 203. When the piston 221 is spaced apart from the air inlet hole 2043, the electronic cigarette enters the second state, the air inlet hole 2043 is communicated with the outside of the electronic cigarette through the liquid guide cavity 204, the gas in the second liquid storage cavity 203 can flow out from the air inlet hole 2043, so that the user is more labor-saving when pressing the button 226, and it is more beneficial for the second atomized liquid to flow into the liquid guide cavity 204.

[0052] When the user stops applying force to the button 226, under the action of the elastic restoring force of the elastic member 223, the connecting rod 222 and the piston 221 move to the direction away from the liquid blocking ball 224, at this time, the region of the lower end of the liquid guide cavity 204 storing air is in a negative pressure state, therefore, the second atomized liquid in the second liquid storage cavity 203 flows into the liquid guide cavity 204 through the liquid inlet hole 2041. The liquid pushing part 2223 pushes the second atomized liquid in the liquid guide cavity 204 out from the liquid guide gap and flows into the first liquid storage cavity 1111 through the liquid outlet hole 2042 and the one-way valve 12, so as to realize the supplement of the atomized liquid. Through the cooperation of the flow distribution groove 2221 and the flow distribution hole 2222, the second atomized liquid flowing out of the liquid inlet hole 2041 can flow to the liquid outlet hole 2042 quickly through the flow distribution groove 2221 and the flow distribution hole 2222. Through the arrangement of the liquid pushing part 2223, the fluid in the liquid guide cavity 204 is driven to move better.

The side wall of the mounting shell 31 is provided with an air inlet hole 311. 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. The second buckling protrusion 322 is buckled and connected to the first buckling protrusion 202. 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, so that the assembly is more convenient. 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.

[0054] 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 atomized liquid to form smoke for the user to smoke. The first electrode 35 is connected to the bracket 32 and extends through the first butt joint hole 1141 into the first butt joint groove 101. The second electrode 36 is connected to the bracket 32 and extends through the second butt joint hole 1142 into the second butt joint groove 102. 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 not only serve the function of electrical connection, but also serve the function of mechanical connection, the connection structure is simplified, the production process is reduced, and the production efficiency is improved.

[0055] The power supply assembly 3 further comprises a sealing block 37 provided with an air passing hole 38 in communication with the atomizing assembly 1.
