Abstract
The utility model discloses an automatic electricity cut off quick-heater, comprising an electric heating pipe, conducting wires and a basal part. A switch which is composed of two opposite conducting strips is arranged on any one conducting wire in the basal part, and a closed insulation box is provided outside the switch. Wherein, one conducting strip is connected with one end of a reset spring, and the other end of the reset spring is fixed on the inner wall of the closed insulation box. A control lever is arranged on one side of the closed insulation box, a thermal bimetallic strip is positioned at the upper part of the control lever, the active layer of the thermal bimetallic strip is positioned at the upper end of the control lever, the upper end of the control lever is connected with a spacing elastic strip which is arranged on the inner wall of the basal part, and the lower end of the control lever is connected with a metallic strip which is provided with a spring through a control rod. One side of the sealed insulation box is provided with a small hole for the control rod to move backwards and forwards, and a vent hole is arranged on the bottom surface of the basal part. The automatic electricity cut off quick-heater has the advantages that disadvantages can be overcome, the automatic electricity cut off can be realized by the temperature of water vapor which enters into the basal part through the venting hole, and the automatic electricity cut off quick-heater is convenient and safe to be used.
Description
Technical field
The utility model relates to a kind of immersion heater, particularly a kind of immersion heater that can cut off the power supply automatically.
