[0048] Example 1

[0049] In order to solve the technical problems in the prior art, the embodiment of the present invention provides a liquid storage device, such as Figure 3 As shown, the liquid reservoir comprises:

[0050] The cylinder 1 is a one-piece formed by spinning, and an air inlet 11 is formed at the first end of the cylinder 1;

[0051] The air intake assembly is provided with a hollow structure, and the air intake assembly is connected with the cylinder 1 through the air intake hole 11; the air intake assembly includes an integrally formed pressing plate 2 and an air intake pipe 3, and the cylinder 1 is connected with the pressing plate 2 through the air intake pipe 3. In this embodiment, the small-diameter hollow structure in the air intake assembly is the air intake pipe 3, and the large-diameter hollow structure is the pressing plate 2. The air intake pipe 3 is directly connected with the cylinder 1, and the pressing plate 2 is connected with the cylinder 1 through the air intake pipe 3.

[0052] The present invention forms an integral cylinder body by spinning, and integrally forms a pressure plate and an intake pipe into an intake assembly, and then welds the cylinder body and the intake assembly to connect them, thereby saving the number of parts during assembly, improving assembly efficiency, and reducing the cost of the liquid reservoir.

[0053] like Figure 3 As shown, when the air intake pipe 3 and the cylinder 1 are assembled, the air intake pipe 3 is sleeved on the outside of the air intake hole 11; in another embodiment, as shown in Figure 4 As shown, when the air intake pipe 3 and the cylinder 1 are assembled, the air intake pipe 3 is embedded in the air intake hole 11. Those skilled in the art can use the above two methods to fix the air intake pipe 3 and the cylinder 1 according to design requirements, which is not specifically limited here.

[0054] The air intake assembly is connected to the air intake hole 11 by welding, so that the air intake assembly is firmly fixed to the cylinder 1, thereby improving the quality of the liquid reservoir. Specifically, the air intake hole 11 extends outward in a direction away from the cylinder 1 to form a connecting pipe, and the length of the connecting pipe is greater than or equal to 3.5 mm. When the connecting pipe is fixed to the air intake pipe 3 by welding, the portion where the connecting pipe and the air intake pipe 3 are fixedly overlapped forms a connecting structure, and the length of the connecting structure is greater than or equal to 3 mm.

[0055] In this embodiment, the material of the pressing plate is stainless steel; the stainless steel pressing plate can improve the quality of the pressing plate, making it less likely to deform and scratch, thereby reducing quality problems of the liquid reservoir and reducing the cost of the liquid reservoir.

[0056] Please continue reading Figure 3 and Figure 4 The liquid reservoir further includes an air intake pipe 5 , a first exhaust hole 12 is formed at the second end of the cylinder 1 , and the air intake pipe 5 is sealedly connected to the first exhaust hole 12 and communicates with the cylinder 1 .

[0065] Furthermore, the present invention provides a method for processing a liquid reservoir, which is used to prepare the liquid reservoir of Example 2, such as Figure 7 As shown, the method comprises the steps of:

[0066] S100: forming a cylinder 1 by a spinning machine, wherein the first end of the cylinder 1 forms the air inlet 11, and the second end of the cylinder 1 forms the opening structure;

[0067] S200: providing an air intake assembly, and welding the air intake pipe to the air intake hole 11, so that the air intake assembly is connected to the cylinder 1;

[0068] S300: providing the end cover 4, and fixing the first end of the end cover 4 to the opening structure, so that the end cover 4 and the cylinder 1 form a communicating cavity;

[0069] S400: providing an air intake pipe 5, and sealingly connecting the air intake pipe 5 to the second exhaust hole 41 and communicating with the cylinder 1.

[0070] The embodiment of the present invention further provides a compressor, comprising the liquid reservoir described in embodiment 2. The compressor can achieve all the technical effects of the above liquid reservoir, which will not be described in detail here.

[0071] The liquid storage device, processing method thereof and compressor provided by the present invention have the following advantages:

[0072] By integrally forming the pressure plate and the air intake pipe into an air intake assembly, and then welding and connecting with the cylinder, the number of parts can be saved, the assembly process can be reduced, the assembly efficiency can be improved, and the cost can be reduced;

[0073] By replacing the pressing plate material with wear-resistant and non-deformable stainless steel, the quality problem of the pressing plate can be reduced;
