Detailed Description
The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications of the present embodiment without inventive contribution as needed after reading the present specification, but all of them are protected by patent law within the scope of the claims of the present invention.
As shown in fig. 1-3, a drainer includes a housing 1, a piston 2 having one end disposed in the housing 1 and capable of sliding up and down along the inner wall of the housing 1, a first through hole 11 disposed at the bottom of the housing 1, an opening/closing device 3 disposed outside the first through hole 11, a driving member 4 disposed at the bottom of the piston 2 for opening the opening/closing device 3, a spring 5 disposed between the piston 2 and the bottom of the housing 1, and a second through hole 31 disposed on the opening/closing device 3 and communicated with the outside.
The opening and closing device 3 comprises a mounting seat 32, a blocking part 33 and a pressure spring 34, one end of the blocking part 33 is blocked by the first through hole 11, the other end of the blocking part is connected with the pressure spring 34, the other end of the pressure spring 34 is fixed at the bottom of the mounting seat 32, the second through hole 31 is arranged on the side wall of the connecting end of the mounting seat 32 and the shell 1, a silica gel sleeve 35 is arranged on the side surface of the blocking part 33, and the silica gel sleeve 35 is abutted to the inner wall of the mounting seat 32.
The driving member 4 is a mandrel with one end fixedly connected with the bottom of the piston 2, and the other end of the driving member 4 contacts with the blocking member 33.
And a sealing ring 6 is arranged on the piston 2, and the outer side of the sealing ring 6 is abutted against the inner wall of the shell 1.
