[0002] Electronic cigarettes are electronic cigarettes. Since electronic cigarettes are similar in appearance to cigarettes and do not contain tar, suspended particulates and other harmful ingredients in traditional cigarettes, some people use them to quit smoking or replace cigarettes.

[0003] Electronic cigarettes introduce smoke oil into the heating component and heat it to produce smoke, giving the user a certain feeling of smoking. The smoke oil is generally filled into the oil cup that forms the smoke oil storage chamber; the smoke oil in the oil cup penetrates into the heating element to heat and atomize; and then inhaled into the user's mouth through the flue.

[0004] Therefore, preventing the leakage of e-liquid and preventing the heating element from burning dry are the problems that e-cigarettes are prone to; how to effectively avoid leakage and burning dry through structural design is an issue that designers must consider. Summary of the invention

[0005] The technical problem solved by the present invention is to provide an electronic cigarette that is anti-leakage and anti-dry burning, and effectively prevents oil leakage and dry burning during use.

[0006] The technical solution of the present invention to solve the above technical problems is:

[0007] The electronic cigarette comprises a nozzle, an oil cup, an oil cup base, a heating wire, a battery tube and a base; the bottom of the oil cup cooperates with the oil cup base to encapsulate the smoke oil and is connected to the battery tube; the battery tube is connected to the base; the nozzle is placed in the channel at the center of the oil cup; the nozzle, the oil cup, the battery tube and the base constitute the overall appearance of the electronic cigarette; the heating wire can atomize the smoke oil; a cylindrical channel is formed in the center of the oil cup; a riveted tube is built into the cylindrical channel of the oil cup, one end of the riveted tube is connected to the nozzle, and the other end is connected to the ventilation pipe; a ventilation hole is provided at the end of the ventilation pipe away from the riveted tube; oil sealing cotton and oil guiding cotton are arranged in sequence corresponding to the positions in the ventilation hole; the heating wire passes through the riveted plug tube Positioned in the oil-conducting cotton; the rivet plug tube is placed in the oil cup base; ventilation holes are provided at corresponding positions where the rivet plug tube and the oil cup base are sleeved and matched; the elongated body formed by the suction nozzle, the rivet tube, the ventilation tube and the rivet plug tube can move relative to the oil cup and the central axial direction of the oil cup base; when the suction nozzle is pulled outward to the outer end, the ventilation holes on the ventilation tube are connected with the inner cavity of the oil cup containing the smoke oil, and the ventilation holes on the rivet plug tube are connected with the ventilation holes of the oil cup base; when the suction nozzle is pressed inward to the inner end, the ventilation holes on the ventilation tube and the inner cavity channel of the oil cup containing the smoke oil are closed, and the ventilation holes on the rivet plug tube and the ventilation holes of the oil cup base are misaligned to close the channels of the two ventilation holes.

[0008] The oil cup base forms a gap after encapsulating the inner cavity of the oil cup containing the tobacco oil, and the gap is closed by the ventilation pipe and the oil sealing cotton; when the suction nozzle axially displaces the ventilation pipe through the riveted tube, the ventilation hole on the ventilation pipe and the gap can form different states of docking and misalignment.

[0016] Figure 2 is a cross-sectional schematic diagram of the electronic cigarette of the present invention when in use;

[0017] Figure 3 It is a cross-sectional schematic diagram of the electronic cigarette of the present invention when not in use. DETAILED DESCRIPTION

[0018] like Figure 1 , 2 As shown, the electronic cigarette of the present invention mainly includes a mouthpiece 1, an oil cup 2, a riveted tube 3, a ventilation tube 4, sealing rings 5 ​​and 10, oil sealing cotton 6, oil guiding cotton 7, a heating wire 8, a riveted plug tube 9, oil sealing silicone 11, a heating wire fixing part 12, an oil cup base 13, a battery tube 14, a battery 15, a sealing silicone 16, a PCB board 17, and a base 18.

[0019] A cylindrical channel is formed in the center of the oil cup 2; the channel wall forming the cylindrical channel and the outer wall of the oil cup 2 form an inner cavity of the oil cup 2 for holding the smoke oil; the bottom of the oil cup 2 (i.e., the opening of the inner cavity) cooperates with the oil cup base 13 to encapsulate the smoke oil. More specifically, the oil cup base 13 encapsulates the inner cavity of the oil cup 2 for holding the smoke oil to form a gap, which is closed by the vent pipe 4 and the oil sealing cotton 6. Corresponding to the position of the gap, a vent hole 41 is provided on the vent pipe 4; the vent hole 41 on the vent pipe 4 and the gap can form different states of docking and misalignment. The position corresponding to the vent hole 41 is sequentially provided with oil sealing cotton 6 and oil guiding cotton 7. The oil cup 2 is also connected to the battery tube 14; the battery tube 14 is connected to the base 18; the suction nozzle 1 is placed in the channel at the center of the oil cup 2; the suction nozzle 1, the oil cup 2, the battery tube 14 and the base 18 constitute the overall appearance of the electronic cigarette.

[0020] The central cylindrical channel of the oil cup 2 is built with a riveted tube 3, one end of the riveted tube 3 is connected to the suction nozzle 1, and the other end is connected to the ventilation pipe 4. A radial expansion part is axially arranged at the position of the central channel of the oil cup 2 corresponding to the suction nozzle 1 for the suction nozzle 1 to move in the axial direction. Relative to the axial direction; the radial size of the suction nozzle 1 is larger than that of the riveted tube 3; it is necessary to form an axial position with a larger radial size in the oil cup 2; in order to be able to axially expand and contract.

[0021] The rivet tube 9 is placed in the oil cup base 13 ; ventilation holes 91 , 131 are correspondingly provided at the positions where the rivet tube 9 and the oil cup base 13 are sleeved and matched; the rivet tube 9 positions the heating wire 8 in the oil guide cotton 7 through the heating wire fixing piece 12 .

[0023] When the mouthpiece 1 is pulled outward, the vent hole 41 on the vent pipe 4 is connected to the inner cavity of the oil cup 2 containing the oil, and the vent hole 92 on the rivet plug tube 9 is connected to the vent hole 131 of the oil cup base 13. At this time, the oil supply channel and air passage of the heating wire 8 are opened, and when the battery 15 is controlled by the PCB board 17 to supply power to the heating wire 8, the heating wire 8 atomizes the oil.

[0024] When the suction nozzle 1 is pressed to the inner end, the vent hole 41 on the vent pipe 4 and the inner cavity channel of the oil cup 2 containing the e-liquid are closed, and the vent hole 91 on the rivet plug tube 9 and the vent hole 131 of the oil cup base 13 are misaligned and the channels of the two vent holes are closed. At this time, the electronic cigarette cannot be used through the suction nozzle 1; the risk of oil leakage due to high oil pressure can be prevented, and the closure of the air inlet can also prevent the heating wire from burning dry and damaging the electronic cigarette when inhaling accidentally.

[0025] In order to effectively seal the smoke oil, a sealing ring is provided between the vent pipe 4 and the channel in the center of the oil cup 2, and between the rivet plug pipe 9 and the oil cup base 13. An oil-sealing silica gel 11 is provided between the vent pipe 4 and the oil cup base 13.

[0026] One end of the suction nozzle 1 is sleeved on one end of the riveted tube 3; a positioning hook is provided at the mutual sleeve connection; the suction nozzle 1 can drive the riveted tube 3, the vent pipe 4, and the riveted plug tube 9 to move relative to the oil cup 2 and the oil cup base 13.

[0027] In order to prevent leakage at the bottom of the electronic cigarette, a sealing silica gel 16 is provided between the battery tube 14 and the base 18 .

[0028] The above embodiments are descriptions of specific implementation methods of the present invention, and are not limitations of the present invention; all equivalent modifications that can be obtained based on the above description should be within the protection scope of the present invention.
