[0078] The outer diameter of the connecting post 423 is smaller than the diameter of the first connecting hole 4211 and the second connecting hole 4212. The first connecting hole 4211 and the second connecting hole 4212 are symmetrically arranged. The diameters of the first connecting hole 4211 and the second connecting hole 4212 are the same and both are smaller than the outer diameter of the columnar shell 421.

[0079] Specifically, the vent valve 42 is configured to consist of a cylindrical housing 421, a first adjusting column 422, a connecting column 423, a second adjusting column 424, and a pressing member 425. The first adjusting column 422 is fixed to one end of the cylindrical housing 421, the connecting column 423 is disposed between the first adjusting column 422 and the second adjusting column 424, the pressing member 425 is fixedly connected to the second adjusting column 424, and the annular flange 4251 of the pressing member 425 is located outside the cylindrical housing 421.

[0094] When the protrusion 4231 is in the snap-fit ​​groove 4223 away from the second adjusting post 424, the adjustable air supply channel is closed; when the protrusion 4231 is in the snap-fit ​​groove 4223 close to the second adjusting post 424, the smaller diameter connecting post 423 is between the first connecting hole 4211 and the second connecting hole 4212, and the adjustable air supply channel is opened.

[0095] In one possible implementation, the outer sidewalls of the first connecting pipe 41 and the second connecting pipe 43 are provided with external thread structures, and the inner sidewall of the sealing end cap 5 is provided with an internal thread structure. The external thread structure is adapted to the internal thread structure to improve the sealing performance of the connection between the first connecting pipe 41 and the second connecting pipe 43 and the external pipe and prevent air leakage.

[0096] In one possible implementation, a sealing ring 4213 is provided at the connection between the cylindrical housing 421 and the pressing member 425 to improve the sealing performance inside the vent valve 42 and prevent air leakage.

[0097] It should be noted that the structures, proportions, sizes, etc., illustrated in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and are not intended to limit the scope of this invention. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of this invention, should still fall within the scope of the disclosed technical content.
