Specific embodiment
The present invention is described in detail with specific embodiment below in conjunction with the accompanying drawings.
Embodiment 1
A kind of compressor liquid storage device, structure as shown in Figure 1, include shell 2, air inlet pipe 3, escape pipe 4 and filter assemblies,
Air inlet pipe 3 is located on shell 2 and is connected to shell 2, and escape pipe 4 is located on shell 2, the straight tube including protruding into shell 2 and storage
Bend pipe outside liquid device, filter assemblies are located in shell 2, are located at below 2 air inlet of shell, above straight tube.It additionally includes
Heart cylindrical-shaped structure, axial direction are equipped with the perforated plate 1 of through-hole array, and structure is as shown in Fig. 2, in the perforated plate 1 and shell 2
Escape pipe 4 is arranged concentrically, and perforated plate 1 is mounted on inside shell 2, and there are certain intervals between 2 inner wall of shell.
