Water faucet switching module

Abstract

The invention discloses a water faucet switching module comprising a switching base, a flow guide block 2 and a flow guide block 1 which are sequentially connected and locked by a locking bolt. A cold water inlet, a cold water outlet through hole, a hot water inlet and an entrance hole are arranged at the bottom of the switching base, a water flow sensor, a radiator and a circuit board are arranged in a cavity of the switching base, the flow guide block 1 comprises a water outlet joint, a cold water inlet guide hole, a cold water outlet guide hole and a water outlet guide hole, and the cold water inlet guide hole, the cold water outlet guide hole and the water outlet guide hole are communicated with the upper end face of the flow guide block 1. When a water faucet valve is opened and controlled in a hot water discharging mode, tap water flows through the cold water inlet, the radiator and the water flow sensor to reach a heating liner, the water flow sensor acquires a sensing signal, the heating liner is powered on to work, hot water flows through the hot water inlet and the water outlet guide hole to reach the water outlet joint, accordingly, the operating state of the electric heating water faucet is automatically controlled, and dry burning due to water shortage is prevented.

Description

technical field [0001] The invention relates to a water faucet switch module for an electric water faucet, in particular to a water faucet switch module capable of automatically controlling the working state of the electric water faucet. Background technique [0002] At present, there are many kinds of known electric water faucet products, mainly including two categories of plastic shell structure and metal shell structure. The end of the electrical switch is connected, the electrical switch is set on the circuit wiring board, and the heating pipe is connected to the circuit wiring board. When the water flow control valve is opened, the water flow pressure acts on the insulating water pressure switch, so that the insulating water pressure switch pushes the electrical switch to close, heating The circuit is connected and the electric hot water faucet works. This electric water faucet electric control device has the advantages of simple structure, low cost, fast temperature r...

AI Technical Summary

Problems solved by technology

This electric water faucet electric control device has the advantages of simple structure, low cost, fast temperature rise, and hot water as soon as it is turned on. However, the defects are also very obvious. It is easy to produce arc phenomenon, but a universal, non-contact electric faucet faucet switch module has not been found in the market. The existing electric faucet electric control device is too large in size, the structure of the circuit wiring board is complicated, and the whole machine is inconvenient to debug.
