Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
The every other embodiment obtained, shall fall within the protection scope of the present invention.
Referring to Fig. 1, the utility model provides a kind of technical solution：A kind of double cavity structure piston pump housing of washing machine, packet
Two-chamber pump case 4 is included, the top of two-chamber pump case 4 is snapped with pump case lid 3, and pump case lid 3 is connect by buckling with two-chamber pump case 4, is pumped
The left and right sides of shell cover 3 is longitudinally plugged with connecting rod 1, and two groups of connecting rods 1 run through pump case lid 3, and the outer wall of connecting rod 1 is socketed with sealing
Lid 2, and sealing cover 2 is connected to the top of pump case lid 3, the outer wall of two groups of connecting rods 1 is socketed with piston 5, and piston 5 is located at double-chamber pump
The inner cavity of shell 4, and piston 5 is bonded with the inner wall of two-chamber pump case 4, the bottom of connecting rod 1 is connected with coupling tube 6, the bottom of coupling tube 6
