Abstract

A thermo-sensitive valve of a bathroom flushing device comprises a valve body provided with a hot water inlet channel and a water outlet channel, a valve core is arranged in the valve body and controls flow-off states of the water flow of the valve body, a thermo-sensitive body is further positioned and installed in the valve body, and responding to the water temperature actuating valve core, the thermo-sensitive body moves toward the direction of a valve port of the hot water inlet channel or a valve port of the water outlet channel. Elastic parts are pressed among the valve core and the valve ports in an abutting-against mode, when the temperature of the water flow entering the valve body exceeds a set value, the thermo-sensitive body actuating valve core compresses the elastic parts and seals the valve ports, when entering the valve body through the water inlet channel, the hot water is perceived immediately by the thermo-sensitive body, if the water temperature exceeds the set value, the thermo-sensitive body immediately actuates the valve core to close the valve ports and prevents the situation that the hot water is drained through the water outlet channel and scalds the human body, wherein the temperature of the hot water exceeds the set value.

Description

A kind of thermovalve of bathroom flushing device

Technical field
