Abstract

A novel pressure switch disclosed by the present invention comprises a pressure switch installed in any fluid pipeline or equipment, the pressure switch is installed between an input end and an output end, and the pressure switch comprises a switch seat, a fluid flow detection valve plate, a silica gel pad, a rubber part support and a trigger rod which are installed between the fluid pipelines. The fluid flow detection valve plate is connected with the silica gel pad, one end of the fluid flow detection valve plate is rotatably connected with the switch seat, the rubber part support is installed on the upper end face of the switch seat, one end of the trigger rod is connected with the silica gel pad, the silica gel part is partially installed in the rubber part support, and the trigger rod is rotatably connected with the rubber part support. According to the invention, the pressure is generated only when the fluid flows, and an object is driven to mechanically act. When the fluid does not flow, no matter how large the pressure is, the pressure on the two faces of the pressure detection valve plate is the same, no acting force or mechanical action is generated, and potential safety hazards such as misoperation and machine burning of the heater are effectively avoided.

Description

Technical field[0001]The present invention relates to a fluid heating apparatus, and more particularly to a new type of pressure switch.Background technique[0002]The electric water heater / electric heating faucet on the market is now constructed of a pressure switch / flow switch, a control board, a power controller, a heating chamber, a heat generating body.[0003]The pressure switch is active in pressure; however, when the water pipe is blocked or the water turns into ice, it will also increase the pressure, and it is easy to cause a burnt machine to cause safety accidents. The flow switch can only provide a flow of flow flow, and cannot generate a mechanical action.Inventive content[0004]The technical problem to be solved by the present invention is a novel pressure switch that effectively solves a safety hazard of heater, burning machine, etc., can effectively solve the safety hazard of heater, burning machine, etc. by installing a mechanical controlled pressure switch in the de...
