Overflow drainage device

Abstract

The invention discloses an overflow drainage device. The overflow drainage device comprises a body shell, a connecting pipeline, a first driving mechanism, a second driving mechanism and a blocking mechanism, wherein a water inlet hole is formed in the side wall of the body shell, a first groove is formed in the bottom of the body shell, one end of the connecting pipeline communicates with the water inlet hole, the other end of the connecting pipeline is connected with a water containing device, the body shell, the connecting pipeline and the water containing device form a communicating vessel, the blocking mechanism is arranged at the first groove and used for blocking water from flowing into the first groove, a water outlet hole is formed in the bottom of the first groove, the first driving mechanism is arranged above the blocking mechanism and connected with the blocking mechanism, and the first driving mechanism drives the blocking mechanism to move upwards under the buoyancy effect of water so that the water inlet hole can communicate with the water outlet hole to achieve overflow. According to the overflow drainage device, the problem of sanitary dead angles caused by the arrangement of overflow holes can be avoided, and the overflow and drainage functions are realized.

Description

technical field [0001] The invention relates to the field of sanitary ware, in particular to an overflow drainage device. Background technique [0002] Most of the water basins of kitchen and bathroom products now have overflow holes, overflow channels or overflow rings, etc., which affect the aesthetics of the water basins, and are prone to sanitary corners, overflow channels are easy to block and are not suitable for cleaning. The water basin without overflow hole is affected by various factors in the process of use, and the water basin overflows and cannot be drained, causing troubles to users in daily use. [0003] Chinese Patent No. CN201521099825.X discloses a water tank overflow protection device, which includes a water tank body and an overflow tank, a faucet is installed on the water tank body; a linkage mechanism, which has a floating ball and a floating arm; and An electric switch circuit, which includes a power supply, two contact pieces, a movable conductor and...

AI Technical Summary

Problems solved by technology

[0004] However, this water tank overflow protection device needs to intervene in circuit components to switch the faucet, the cost is high and the electronic components need to be replaced regularly, and the maintenance is troublesome; in addition, on the premise that there is a drain hole, it is necessary to set up an additional connection with the overflow tank. The overflow hole affects the aesthetics of the water basin, and it is also prone to sanitary corners, and the overflow channel is easy to block and is not suitable for cleaning; at the same time, when the user needs to discharge the sewage after cleaning the object, he needs to touch the drainage switch under the sewage twice to drain. not hygienic
