Drainage device of push-pull device
The invention discloses a drainage device of a push-pull device. The drainage device comprises a drainage box, wherein the drainage box comprises a first trough body and a drainage chamber body, the first trough body is communicated with a first end of the drainage chamber body, and the first end of the drainage chamber body is communicated with a second end of the drainage chamber body. The drainage device further comprises a water plugging block, wherein the water plugging block comprises a first connecting part, the first connecting part penetrates through a downwards-sliding first opening of the push-pull device and is fixedly arranged in the first trough body, and the drainage box is arranged in a downwards-sliding chamber body; the second end of the drainage chamber body extends out of a downwards-sliding second opening of the push-pull device. The drainage device further comprises a first one-way valve, wherein the first one-way valve is arranged on the first connecting part and is used for controlling opening and closing a communicated passageway between the first trough body and the drainage chamber body. The drainage device of the push-pull device, disclosed by the invention, has the advantage that the problems of the current push-pull devices that air tightness and water tightness are poor and rainwater backwards flows indoors can be solved.
