Description

Technical Field

[0001] The utility model relates to the technical field of electronic cigarettes, in particular to a structure for preventing silica gel on an electronic cigarette oil tank from leaking air or oil. Background Art

[0002] E-cigarettes typically have a reservoir containing cotton oil. The hollow center of the cotton oil reservoir forms an axial atomization channel. A silicone sealant is placed above the cotton oil reservoir, which mates with the reservoir top to create a seal. A through-hole is also provided in the center of the silicone oil reservoir, corresponding to the atomization channel, to allow vapor to pass through. However, due to the size limitations of e-cigarettes and the inherent material of the silicone oil reservoir, which can cause the through-hole to collapse, the junction between the reservoir and the silicone oil reservoir is prone to air and oil leaks. Utility Model Content

[0003] The technical problem solved by the utility model is to provide a structure to prevent the silicone on the electronic cigarette oil tank from leaking air and oil, and to avoid the problem of air and oil leakage at the junction of the silicone on the oil tank and the oil tank.

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

[0005] The structure includes an oil bin, oil storage cotton and silicone on the oil bin. The oil storage cotton is arranged in the oil bin, and the silicone on the oil bin is sealed on the top of the oil bin. An atomization channel is arranged axially in the center of the oil storage cotton, and a through hole is arranged on the silicone on the oil bin corresponding to the atomization channel. The through hole of the silicone on the oil bin is provided with a supporting hardware tube.

[0006] The hardware pipe is slightly retracted inwardly to the end surface of the silica gel on the oil tank in the axial direction.

[0007] The surface of the silica gel on the oil bin that matches the inner side surface of the oil bin protrudes an annular interference fit ring.

[0008] The utility model installs a circular hardware steel ring support on the silica gel smoke outlet channel on the oil bin to ensure that the silica gel sealing rib on the oil bin and the oil cup are sealed, thereby avoiding the problem of gas leakage and oil leakage of silica gel on the oil bin. BRIEF DESCRIPTION OF THE DRAWINGS

[0009] The present invention is further described below with reference to the accompanying drawings:

[0010] Figure 1 This is a main cross-sectional view of the electronic cigarette of the utility model;

[0011] Figure 2 This is a side sectional view of the electronic cigarette of the present invention;

[0012] Figure 3 This is an enlarged cross-sectional view of the junction between the electronic cigarette oil tank 1 and the silicone rubber 3 on the oil tank of the present invention. DETAILED DESCRIPTION

[0013] like Figure 1-3 As shown, the structure of the utility model includes an oil bin 1, oil storage cotton 2 and oil bin upper silica gel 3. The oil storage cotton 2 is arranged in the oil bin 1, and the oil bin upper silica gel 3 is sealed at the top of the oil bin 1; an atomization channel is arranged axially in the center of the oil storage cotton 2, and a through hole is arranged on the oil bin upper silica gel 3 corresponding to the atomization channel.

[0014] A supporting hardware tube 4 is installed within the through-hole of the oil silo 3. The hardware tube 4 is slightly recessed axially from the end surface of the oil silo 3. An annular interference fit ring 31 extends from the surface of the oil silo 3 that mates with the inner surface of the oil silo 1. The support provided by the hardware tube 4 ensures that the interference fit ring 31 adheres tightly to the inner surface of the oil silo 1, preventing oil and air leaks at the junction of the oil silo 3 and the oil silo 1 due to the soft plasticity of the silicone.

[0015] The remaining structure of the electronic cigarette of the present invention is shown in the figure, which is the same as that of the existing electronic cigarette; it will not be described in detail here.

[0016] The above embodiments are descriptions of specific implementation methods of the present invention, and are not limitations of the present invention; all equivalent modifications based on the above descriptions should fall within the scope of protection of the present invention.
