Description

Technical Field

[0001] The utility model relates to the technical field of fasteners, in particular to a fastening structure. Background Art

[0002] Electronic cigarettes are electronic products that imitate cigarettes, with the same appearance, smoke, taste and feel as cigarettes. Electronic cigarettes use chips and air switches to control the smoke output and working status. Inside the electronic cigarette, the electronic cigarette liquid is transmitted to the atomization chamber through nickel foam and atomized into droplets with a diameter of about 0.5-1.5um. When using it, the user turns on the smoking air switch and inhales the droplets through the filter tip into the lungs for absorption. The chip is driven by the current of the lithium battery to control the operation of the atomization chamber. The heating wire in the atomization chamber generates high temperature, atomizes the smoke liquid, and thus forms a vapor mist that simulates smoke.

[0003] Existing e-cigarettes use sponges to block the gap between the filter and the cigarette bomb body. After the oil soaks the sponge, the air holes in the sponge are blocked, the sponge's suction resistance increases, and it cannot be restored to a normal state. It is directly scrapped and cannot be used. It is difficult to seal the gap and is prone to oil leakage. The mouth will directly contact the oil, resulting in a poor experience. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a fastening structure that can continuously maintain sealing performance, prevent oil leakage, prevent oil from contacting the user's mouth, and improve the user experience.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0006] The utility model provides a fastening structure, comprising a fitting part and a mounting part coaxially arranged with the fitting part, a flue is passed through the fitting part and the two ends of the mounting part, an elastic sealing part is installed on the periphery of the mounting part, and the projection of the elastic sealing part along the axial direction of the fitting part is located inside the fitting part.

[0007] Wherein, a first stop edge and a second stop edge are provided on the outer side of the mounting portion, and a positioning space for accommodating the elastic sealing component is provided between the first stop edge and the second stop edge.

[0008] The first stop edge and the second stop edge are in an annular structure, the elastic seal is in an annular structure, and the inner end of the elastic seal extends into the positioning space.

[0009] Wherein, the first stop edge and the second stop edge both extend along the circumference of the mounting portion.

[0010] The outer side surface of the first stop edge is inclined, and two ends of the outer side surface of the first stop edge abut against the outer side of the mounting portion and the surface of the elastic sealing component respectively.

[0011] The outer side surface of the second stop edge is inclined, and two ends of the outer side surface of the second stop edge abut against the outer side of the mounting portion and the surface of the elastic sealing component respectively.

[0012] The diameter of the fitting portion is greater than the diameter of the mounting portion, one end surface of the fitting portion close to the mounting portion is perpendicular to the axis of the fitting portion, and the other end surface of the fitting portion adopts a rounded transition.

[0013] The outer side of the fitting portion is arc-shaped, and the middle part of the arc is concave inwards.

[0014] Beneficial effects of the utility model:

[0015] The utility model effectively seals the gap between the filter and the cigarette bomb body through an elastic seal. When the elastic seal is subjected to the pressure impact of the oil, it will be deformed. The pressure is within the recoverable elastic range of the elastic seal. Therefore, the structure can continuously maintain the sealing performance, avoid oil leakage, prevent oil from contacting the user's mouth, and enhance the user experience.

The first stop edge 5 and the second stop edge 6 are annular structures, and the elastic seal 4 is annular structure. The inner end of the elastic seal 4 extends into the positioning space.

[0024] refer to Figures 1 to 3 As shown, in actual application, the mounting portion 2 is coaxially mounted with the cigarette bomb body, and the flow channel of the oil between the cigarette bomb body and the mounting portion 2 is connected through the flue 3. The inner and outer ends of the elastic seal 4 are tightly abutted against the outer side of the mounting portion 2 and the inner wall of the cigarette bomb body. The mounting portion 2 and the fitting portion 1 correspond to the filter structure as a whole, so that the gap between the filter and the cigarette bomb body is effectively sealed by the elastic seal 4. When the elastic seal 4 is subjected to the pressure impact of the oil, it will be deformed by force. The pressure is within the recoverable elastic range of the elastic seal 4. Therefore, the structure can continuously maintain the sealing performance, avoid leakage of oil, prevent oil from contacting the user's mouth, and improve the user experience; during installation, the inner end of the elastic seal 4 can be extended between the first stop edge 5 and the second stop edge 6, and the elastic seal 4 can be installed through the positioning space to effectively prevent the elastic seal 4 from sliding, with accurate positioning, convenient disassembly and assembly, and convenient replacement; refer to Figure 1 , 3 As shown, the first retaining edge 5 and the second retaining edge 6 both extend along the circumference of the mounting portion 2, so that each radial section of the mounting portion 2 is subjected to the same oil pressure, thereby ensuring that the elastic seal 4 is subjected to uniform force, ensuring the structural stability of the elastic seal 4, and improving the safety of use of the elastic seal 4; specifically, a plurality of pairs of first retaining edges 5 and second retaining edges 6 are provided on the mounting portion 2, and an elastic seal 4 is installed between every two first retaining edges 5 and second retaining edges 6 to improve the sealing effect of the gap.
