Abstract

The invention discloses a small double-break temperature controller. The small double-break temperature controller comprises a base, an upper cover, a temperature sensing assembly and an adjusting screw; the temperature sensing assembly consists of a probe, a capillary, a membrane seat, a membrane box and a membrane sheet mat; a micro switch consists of two static contact components and two dynamic contact components, and the micro switch is arranged in the base; the adjusting screw is arranged on the upper cover; the membrane seat is arranged in a central hole of the adjusting screw; an insulating mat is arranged between the upper cover and the base; a bracket is fixed on the base; one end of a hanging plate is arranged in a groove of the bracket, and the other end of the hanging plate is riveted with a push piece; the two dynamic contact components of the push piece moves up and down; one end of a seesaw is arranged in the groove of the bracket, the other end of the seesaw is connected with a seesaw sheet arranged on the hanging plate, and the seesaw takes a pressure spring arranged on the base as a pivot; and a spring plate is fixed below the upper cover, a lug boss of the spring plate is propped against the membrane sheet mat, and a top ball riveted under the spring plate is propped on the lug boss of the spring plate. The small double-break temperature controller is used for an electric heating auxiliary device of a solar water heater.

Description

technical field [0001] The invention relates to a thermostat, in particular to a small double-break thermostat used for an electric heating auxiliary device of a solar water heater. Background technique [0002] Solar water heater refers to a water heater that uses solar energy as energy for heating. It is one of the three major water heaters alongside gas water heaters and electric water heaters. In winter or cloudy days, solar water heaters must be equipped with electric heating auxiliary devices, otherwise they cannot be used. [0003] The applicant once designed a "three-phase dual-control thermostat" (China, announcement number CN2768186Y, announcement date March 29, 2006), which includes a base, a cover shell, a temperature control end probe, a temperature control end capillary, The temperature-controlling and temperature-sensing membrane box component constitutes the temperature-controlling and temperature-sensing component, the adjusting knob, adjusting screw, cente...
