Description

Technical Field

[0001] This utility model relates to the field of electronic cigarette technology, and specifically to an electronic cigarette that prevents oil leakage by using a piston to release pressure. Background Technology

[0002] like Figure 1 , 2 As shown, this is a conventional large-capacity e-cigarette with e-liquid. An atomizing tube 2 is axially positioned at the center of the e-liquid tank 1. An e-liquid storage cotton 3 and an atomizing coil 4 are housed inside the atomizing tube 2. An e-liquid inlet 21 is located at the bottom of the atomizing tube 2. A mouthpiece 11 is integrally formed at the top of the e-liquid tank 1, communicating with the atomization channel of the e-liquid storage cotton 3. An e-liquid tank support 5 is located at the bottom of the e-liquid tank 1, and a support sealing silicone 6 is installed above the support 5. Therefore, a sealed e-liquid storage space 12 is formed inside the e-liquid tank 1 through the atomizing tube 2 and the support sealing silicone 6. The e-liquid in the storage space 12 can seep into the e-liquid storage cotton 3 through the e-liquid inlet 21. Although it has advantages such as large capacity and long continuous use time, after a period of vaping, a large amount of air will accumulate in the e-liquid tank 1. In high-temperature environments such as summer, the air inside the e-liquid tank 1 expands thermally, increasing the internal pressure of the e-liquid tank 1. This thermal expansion will force the e-liquid in the e-liquid tank 1 through the e-liquid inlet 21 into the e-liquid storage cotton 3 inside the atomizing tube 2. If there is too much e-liquid in the atomizer tube 2, the oil reservoir cotton 3 will not be able to hold the excess e-liquid; when the e-cigarette is laid flat, the e-liquid will leak out from the mouthpiece. Utility Model Content

[0003] The technical problem solved by this invention is to provide an electronic cigarette that prevents oil leakage by using a piston to release pressure; it can regulate the air pressure balance in the oil tank; and ensure that oil leakage will not occur due to excessive oil tank pressure.

[0004] The technical solution of this utility model to solve the above-mentioned technical problems is:

[0005] The electronic cigarette includes an oil tank, an oil tank support, and a support sealing silicone. The oil tank support is located at the bottom of the oil tank. The support sealing silicone is located above the oil tank support. A piston channel is provided on the oil tank support. A pressure relief component is provided inside the piston channel. The support sealing silicone has a pressure relief hole corresponding to the piston channel. When the internal pressure of the oil tank increases, the pressure relief component can move away from the support sealing silicone inside the piston channel.

[0006] The piston channel is a cylinder with an axial projection that is I-shaped.

[0007] The pressure relief component is a silicone plug with an axial hole in its center; a transverse partition with an axial vent is provided in the middle of the axial hole, and a silicone plug is sealed at the bottom of the axial hole.

[0008] The pressure relief holes on the silicone sealant of the bracket are micropores with extremely small diameters.

[0009] Oil-absorbing cotton is provided below the piston channel.

[0010] This invention utilizes the cooperation of a piston channel and a pressure relief component. When the internal pressure of the oil tank increases, it can be transmitted to the pressure relief component through the pressure relief hole in the silicone sealant of the bracket. The axial movement of the pressure relief component adjusts the pressure in the oil tank space, preventing oil leakage and other problems. The oil-absorbing cotton installed below the pressure relief component can absorb the e-liquid squeezed out due to excessive pressure, and also limit the position of the pressure relief component, preventing it from running out of the piston channel.

[0017] The following embodiments are descriptions of specific implementations of the present utility model. These descriptions are intended to facilitate understanding of the technical solutions of this application by those skilled in the art and are not intended to limit the scope of protection of the technical solutions of the present utility model. All equivalent transformations that can be obtained from the description of the embodiments of the present utility model should be within the scope of protection of the present utility model.

[0018] like Figures 3 to 5 As shown, the electronic cigarette of this utility model includes an oil tank 1, an atomizing tube 2, an oil storage cotton 3, an atomizing core 4, an oil tank support 4, and a support sealing silicone 5; the atomizing tube 2 is axially arranged in the center of the oil tank 1; the oil storage cotton 3 and the atomizing core 4 are arranged inside the atomizing tube 2; an oil inlet 21 is provided at the bottom end of the atomizing tube 2. The top of the oil tank 1 is integrally formed with a mouthpiece 11, which communicates with the atomization channel of the oil storage cotton 3. The oil tank support 5 is provided at the bottom of the oil tank 1, and the support sealing silicone 6 is provided above the oil tank support 5.

[0019] A piston channel 51 is provided on the oil tank support 5; the piston channel 51 is a cylinder with an axial projection in the shape of an I.

[0020] A pressure relief component 7 is installed inside the piston passage 51; the pressure relief component 7 is a silicone plug, with an axial hole 71 formed in its center. A transverse partition with an axial vent hole 72 is provided in the middle of the axial hole 71. Through the vent hole 72, the silicone plug can be inserted into the piston passage 51 to release air, allowing air above the silicone plug and inside the piston passage to escape. A sealing plug 73 is installed at the bottom of the axial hole 71; the sealing plug 73 is made of KAFT or UV adhesive; after the silicone plug is inserted into the piston passage 51, the axial hole 71 in the middle is sealed with adhesive. An interference fit is made between the piston passage 51 and the pressure relief component 7 to ensure no oil leakage.

[0021] like Figure 4 As shown, the pressure relief component 7 is smaller at the top and larger at the bottom; the change in the upper and lower dimensions forms a step; combined with the step formed by the radial dimension change of the piston channel 51, the pressure relief component 7 is limited to the top position of the piston channel 51.

[0022] The support sealing silicone 6 is provided with a pressure relief hole 61 corresponding to the piston channel 51. The pressure relief hole 61 is a micro-hole with a very small diameter left by the oil injection needle puncture.

[0023] like Figure 5 As shown, when the internal pressure of the oil tank 1 increases, the pressure relief component 7 can move away from the support sealing silicone 6 in the piston channel 51; by moving the pressure relief component 7, the space enclosed above the pressure relief component 7 is adjusted; thereby adjusting the pressure of the oil tank 1.

[0024] In addition, an oil-absorbing cotton 8 is provided below the piston passage 51; on the one hand, it prevents oil leakage; on the other hand, it can also limit the pressure relief component 7 within the piston passage 51.

[0025] The structure of the remaining parts of the electronic cigarette of this utility model is shown in the figure. The remaining parts are not related to the implementation of the aforementioned scheme; they will not be described in detail here.
