Liquid storage device

The utility model provides a liquid storage device. The device comprises a shell and an air suction pipe, a liquid storage cavity is formed in the shell, a suction inlet communicated with the liquid storage cavity is formed in the shell, the air suction pipe extends into the liquid storage cavity through the suction inlet, a sleeve is arranged between the air suction pipe and the suction inlet, the sleeve is fixedly arranged outside the air suction pipe in a sleeving mode, and the outer wall of the sleeve is fixedly connected with the inner wall of the suction inlet. Compared with the prior art, the casing pipe is arranged between the shell and the air suction pipe, so that the rigidity of the air suction pipe is improved, irregular stress borne by the air suction pipe is reduced, the airsuction pipe is not prone to breakage, and therefore in a severe vibration test, the compressor can still stably and efficiently operate so as to meet the requirements of customers; and on the other hand, in daily application
