In some embodiments, referring to fig. 2, the sealing member 3 includes a sealing member body 31, and the sealing member body 31 is provided with a first through hole 311 extending in an axial direction. One end of the sealing element body 31 protrudes and extends with a first inserting column 32 along the axial direction, and the first inserting column 32 is a hollow structure and is communicated with the first through hole 311. The other end of the sealing element body 31 is protruded with a second plug column 33 along the axial direction, that is, the protruding direction of the second plug column 33 deviates from the first plug column 32. The second plug column 33 is hollow and is connected to the first through hole 311. Preferably, the first inserting column 32 and the second inserting column 33 are coaxially arranged with the first through hole 311, and the inner walls of the joints are smoothly connected, so that the resistance of gas circulation can be reduced, and the gas circulation is smoother.

Therefore, the pressure relief path can be shortened, and the pressure relief efficiency can be improved. The vent grooves 331 may be one, two or more. Preferably, the number of the vent grooves 331 is two, and the two vent grooves 331 are symmetrically distributed on the outer wall of the second plug column 33, so that the pressure relief requirement is met, and the connection strength between the second plug column 33 and the sleeve 21 is ensured.

When oil is injected into the oil storage chamber 6, the oil storage member 7 absorbs the oil, expands, and abuts against the limit bar 312. Because the limiting strip 312 is convexly arranged on the sealing element body 31, the oil storage part 7 cannot be tightly attached to the sealing element 3, the inlet of the air release channel 8 is effectively prevented from being blocked by the oil storage part 7, and the smoothness of the air release channel 8 is ensured. In practical applications, the oil storage member 7 is made of a porous material or a fiber material. For example, the oil storage member 7 may be made of cotton, foam, porous ceramic, or the like.

In order to increase the insertion strength and the sealing effect between the first insertion column 32 and the annular groove 122, the outer periphery of the first insertion column 32 is provided with at least one rib 321 along the circumferential direction. When the first plug-in post 32 is inserted into the suction opening 12, the at least one rib 321 elastically abuts against the inner wall of the annular groove 122. Further, an end of the first plug-in post 32 away from the sealing element body 31 and the annular groove 122 enclose an annular cavity, and the annular cavity is filled with an oil absorbing member. Since the annular groove 122 is communicated with the second through hole 121, the condensate generated in the second through hole 121 can flow into the annular cavity and be absorbed by the liquid absorbing member, so that the condensate flowing into the atomizing passage 5 can be reduced. In practical application, the liquid absorbing piece can be made of oil absorbing cotton, foam cotton and other materials.

In some embodiments, the base 4 is provided with a third through hole 43 extending along the axial direction, and the third through hole 43 is communicated with the sleeve 21, so that the third through hole 43, the sleeve 21, the second plug-in post 33, the first through hole 311, the first plug-in post 32 and the suction port 12 are communicated in sequence to form the atomization channel 5. The other end of the third through hole 43 is communicated with the outside air, so that the third through hole 43 is used as the air inlet end of the atomizing channel 5, and the suction port 12 is used as the air outlet end of the atomizing channel 5. In practical application, the base 4 may be an integral structure or a separate structure. For example, the base 4 may include a base body 41 and a seal seat 42. One end of the sealing seat 42 is inserted into the sleeve 21, the other end is fastened with the base body 41, and the periphery of the sealing seat 42 is elastically abutted against the inner wall of the opening 11 of the housing 1 to seal the opening 11, so that the oil in the oil storage chamber 6 is prevented from leaking out of the opening 11. The sealing seat 42 is made of an elastic material, such as silicone rubber, rubber or silicon rubber. The base body 41 is fastened to the sealing seat 42 and is in interference fit with the opening 11 of the housing 1, so as to cover the sealing seat 42 and prevent the sealing seat 42 from being separated from the housing 1.
