Description

Technical Field

[0001] This utility model relates to a water flow switch. Background Technology

[0002] The existing technology, Chinese patent 201410569477.1, describes a flow-sensing insulating wall connection assembly, comprising a body made of insulating material, inlet and outlet water pipes made of insulating material, and a silicone pad. It also includes a Hall effect switch sensor and a flow rotor with a magnet. The inner diameter of the cylindrical interface of the inlet and outlet water pipes is the same as the diameter of the water channel. The flow rotor is disposed within the water channel, with the cylindrical interface of the inlet and outlet water pipes inserted into a countersunk hole. The upper part of the flow rotor is located within the cylindrical interface, and the flow rotor rotatably engages with the water channel and the cylindrical interface. The axial end face of the silicone pad on the inlet and outlet water pipes is in contact with the bottom plate of the connecting hole and the top annular plate of the cylindrical interface. The Hall effect switch sensor is disposed on a base and engages with the flow rotor. The problem is that it needs to be inserted into the inner tank of an electric water heater during use and cannot be installed on the inlet or outlet water pipes of the water heater.

The main body includes a water inlet chamber, a water sealing chamber, a water inlet pipe, an intermediate water pipe, an outlet pipe, and a sensor hole. The water inlet pipe and the intermediate water pipe are connected in series via a water tank; the intermediate water pipe and the outlet pipe are connected in series; the sensor hole intersects with the intermediate water pipe and the outlet pipe in series, or in other words, the end of the sensor hole connects the intermediate water pipe and the outlet pipe in series. The end cover plate includes a water guide hole and a radial water guide groove, which are connected. The end cover plate is fixed and sealed to the water sealing chamber, and the water guide hole is connected to the outlet pipe. The end cover plate covers the water inlet pipe, the outlet pipe, and the water tank in series. The temperature sensor is fixed to the sensor hole. The problem is that it lacks a water flow switch or water flow sensing function. Utility Model Content
