[0043] An air intake pipe 2 , wherein the air intake pipe 2 is sealed and connected to the exhaust hole 13 and communicates with the cylinder 1 .

[0044] The cylinder is formed as an integral part by spinning, an air inlet is formed at the first end of the cylinder, and the second end of the cylinder is a closed structure, thereby eliminating the end cover in the original three-stage liquid reservoir, saving parts during assembly of the liquid reservoir and solder during welding of parts, thereby improving the assembly efficiency of the liquid reservoir and reducing the cost of the liquid reservoir.

[0045] Please continue reading Figure 2 The liquid reservoir further comprises an air intake assembly, which is connected to the cylinder 1 through the air intake hole 11. The air intake assembly comprises an air intake pipe 3 and a pressing plate 4.

[0052] S200: The second end of the cylinder 1 is welded to form the closed structure 12; after the cylinder 1 is spun, two mounting holes are formed at the axial ends of the cylinder 1, that is, the two ends of the cavity of the cylinder 1 are connected to the external environment, wherein the mounting hole at the first end is the air inlet 11, and the mounting hole at the second end is welded to form the closed structure 12, so that the cylinder 1 forms a semi-closed cavity; the welding method is, for example, argon arc welding, laser welding, etc., and the specific welding method is not limited, as long as the second end of the cylinder 1 can be formed into a closed structure;

[0053] S300: forming at least one exhaust hole 13 on the side wall of the cylinder 1;

[0054] S400: Provide the same number of the air intake pipes 2 as the air exhaust holes 13, and seal the air intake pipes 2 to the air exhaust holes 13 and connect them to the cylinder 1.
