Mixing valve and faucet

Abstract

The invention relates to a mixing valve and a faucet device. The mixing valve comprises a valve seat and a valve mechanism. A first flow path, a second flow path and a mixing flow path are defined by the valve seat. The valve mechanism comprises an inner shell part, a valve rod mechanism rotationally mounted in the inner shell part and a stopping part. A first stopping face and a second stopping face are defined by the inner shell part. The valve rod mechanism comprises a valve rod and a valve plate part which is mounted at the first end of the valve rod and provided with a first adjusting hole and a second adjusting hole, a mixing cavity in fluid communication with the mixing flow path is defined by the valve plate part and the inner shell part together, the first flow path is constructed to be selectively in fluid communication with the first adjusting hole, and the second flow path is constructed to be selectively in fluid communication with the second adjusting hole. The stopping part is mounted at the second end of the valve rod. It is constructed that when the valve rod mechanism rotates within the rotating range between the first position where the stopping part is in contact with the first stopping face and the second position where the stopping part is in contact with the second stopping face, the mixing cavity is kept in fluid communication with at least one of the first flow path and the second flow path. The mixing valve and the faucet device are simple in structure and convenient for a user to operate.

Description

technical field [0001] The invention relates to the technical field of fluid switches, in particular to a mixing valve and a faucet device Background technique [0002] Existing faucets usually only have switching valves to control the on-off of the waterway, or are equipped with a hybrid switching valve that integrates the functions of temperature adjustment and waterway switching to realize the control of temperature and waterway on-off. [0003] CN204828773U discloses a "clean water faucet without pulling out", which controls the on-off of the water circuit and regulates the water temperature by means of a mixing regulating valve. Every time the tap is turned on, the user needs to turn the handle to readjust the water temperature. [0004] DE102011076828A1 discloses a "valve insert for sanitary fittings", which is provided with a switching valve with a single function to control the on-off of the water circuit, but does not have the function of adjusting the water temper...
