In this embodiment, the fourth through hole 210 is configured in the specific manner, so that a larger space can be provided for distributing the outlet pipe for the valve port of the steel cylinder, thereby facilitating the distribution of the outlet pipe.

The shape of the protrusion 111 is not limited, and may be adjusted according to actual needs.

As an example, the shape of the protrusion 111 is a circular arc.

In this embodiment, the protrusion 111 is configured to be circular arc, so that the joint of the inner wall of the fourth through hole 210 is smoother, and a larger operable space is provided.

It will be appreciated that the more points of bolting, the better the connection stability of the peripheral wall 120 to the sleeve 200, and the structure of the peripheral wall 120 and the sleeve 200 may be adjusted to further enhance the connection stability of the two.

As an example, the peripheral wall 120 is provided with a plurality of first screw holes 123 spaced apart from each other, and the sleeve 200 is provided with a plurality of second screw holes 220 spaced apart from each other, where the plurality of first screw holes 123 and the plurality of second screw holes 220 are in one-to-one correspondence with each other.

The plurality of first screw holes 123 and the plurality of second screw holes 220 are respectively distributed at intervals along the circumferential direction of the peripheral wall 120 and the circumferential direction of the sleeve 200.

In this embodiment, a plurality of first screw holes 123 and second screw holes 220 are formed, which are respectively in one-to-one correspondence, that is, a plurality of bolt fixing portions are provided, so that the connection between the peripheral wall 120 and the sleeve 200 is firmer, and the stability of the overall structure of the portable air extraction device is improved.

It will be appreciated that different connection modes of the sleeve may affect the overall volume of the portable air extraction device 10, so that the connection modes of the sleeve may be adjusted in order to make the overall structure of the portable air extraction device 10 compact.

As an example, the peripheral wall 120 is sleeved on the outer wall of the sleeve 200.

In this embodiment, the peripheral wall 120 is sleeved on the outer wall of the sleeve 200, and the sleeve 200 has the advantage of a more compact structure than the sleeve 200 is sleeved on the outer wall of the peripheral wall 120, and accordingly, the sleeve has a smaller space occupation.

In other possible embodiments, the sleeve 200 may also be sleeved on the outer wall of the peripheral wall 120.

It will be appreciated that the distance dimension from the peripheral wall 120 to the outer wall of the cylinder port may be adjusted in view of the convenience of valve operation.
