Abstract
The utility model relates to a water-control switch, belonging to the electric switch, comprising a upper body 1, a lower body 2, a contact electric switch 6, a elastic strip 3, a knockout pin 4 and other members, which is characterized in that: the elastic strip is fixedly arranged between the upper body and the lower body; a water feeding connector is connected with the lower body; an water effusing interface is arranged at one side; the knockout pin covered with a spring is also arranged between the elastic strip and the upper body; the knockout-pin head goes through the upper body to correspond with the contact electric switch; the power supply switches on when a certain hydraulic pressure is existing between the lower body and the elastic strip; the power supply cuts off when the hydraulic pressure is zero or too little. The utility model has the advantages that: the water-control switch is suitable for the electric water heater; burning out the electric water heater when no water feeding and scalding people because of the too high temperature of the water when too little water feeding are avoided.
Description
Technical field
The utility model relates to a kind of electric switch, particularly a kind of electric heater water-control switch.
Background technology
Existing electric heater divides two kinds of storage type and quick-heating types, and the storage type electric heater is inconvenient owing to needing heating in advance use; Quick-heating type electric water heater is except that electrical heating elements, and switch is the critical component that guarantees safety, and known implementation has two kinds: a kind of is that electric switch, taps separate, and another kind is to adopt electromagnetically operated valve, and power supply is opened then valve and opened.But all there is shortcoming in two kinds of methods: electrical heating elements is burnt out because of continuing energising when water inlet pipe is anhydrous, and hydraulic pressure causes the too high easy scald people of water temperature when too small.
Summary of the invention
Technical problem to be solved in the utility model provides when water inlet pipe the water-control switch that can cut off the electricity supply automatically when anhydrous or hydraulic pressure is too small.
The utility model water-control switch comprises upper body, lower body, contact electric switch, water supply connector, water outlet interface; Upper body and lower body are fastenedly connected, be connected with water supply connector on the lower body, one side has the water outlet interface, the contact electric switch is installed on the upper body, it is characterized in that being installed with flexure strip between upper body and the lower body, between flexure strip and the upper body push rod is arranged, push rod is with spring outward, and it is corresponding with the contact electric switch that push rod head is passed the upper body.Adopt the water-control switch of this structure, when between lower body and the flexure strip certain hydraulic pressure being arranged, the flexure strip middle part promotes push rod and rises the contact arm of push rod crown upper contact electric switch, energized to upper process; When anhydrous between lower body and the flexure strip or hydraulic pressure was too small, the flexure strip protruding part descended, and push rod falls after rise under spring action, and the contact arm of contact electric switch resets, deenergization.This water-control switch is applied to electric heater, can avoid not having water inlet or intakes when too small, and electric heater continues heating and burns out electric heater; Or water temperature is too high, and people's accident takes place to scald.
