Bathtub drainer

Abstract

The invention discloses a bathtub drainer. The bathtub drainer comprises an overflow device and a drainage device, wherein the overflow device and the drainage device communicate with each other and are installed at an overflow opening and a drainage opening of a bathtub respectively, the overflow device is provided with a switch piece and a key assembly, one side of the switch piece is rotatablymounted at the overflow opening, and the key assembly is mounted on the switch piece or the overflow opening to lock or unlock the switch piece; and the bathtub drainer is further comprises a transmission assembly, wherein one end of the transmission assembly is in transmission connection with the drainage device, and the other end of the transmission assembly is rotationally connected with the switch piece, so that when the drainage device closes the drainage opening and the switch piece is unlocked, the switch piece is driven to act to open the overflow opening, or when the switch piece is locked, the drainage device is driven to act to open the drainage opening. According to the bathtub drainer, large-flow overflow can be realized, occupied volume is small, the space between a cylinderbody and a skirt part is reduced, and disassembling and assembling are convenient.

Description

technical field [0001] The invention relates to the field of sanitary ware, in particular to a bathtub drainer. Background technique [0002] At present, the existing bathtub is provided with an overflow drainer assembly, and the switch of the drainage device is controlled by a control part, and the control part mainly adopts circular handwheel rotation or button pressing. The circular rotation opening method relies on the through hole on the handwheel cover and the matching gap to realize overflow, the overflow flow is small and cannot meet the corresponding recommended standards; at the same time, the structure without force conversion requires laborious operation, and the operation methods of accessories of various brands are different Not big enough to meet the needs of more consumers. [0003] The one-piece skirt cylinder on the market has the following deficiencies after using the overflow drain assembly with handwheel: [0004] During installation and construction, ...

AI Technical Summary

Problems solved by technology

[0004] During installation and construction, it is necessary to tighten the connection by thread and fix it behind the bathtub by hand, which is very troublesome; at the same time, the overall size of the overflow assembly is too large to meet the small gap between the skirt and the cylinder body; if the cylinder body The gap with the skirt is too small to be fixed by hand. When the overflow component is damaged, it cannot be repaired. The skirt can only be cut again. The maintenance work is extremely heavy and takes a long time

The height of the exposed cylinder surface is too high, affecting the appearance
