Description

Technical Field

[0001] The utility model relates to a temperature control device, in particular to a conveniently assembled temperature controller. Background Art

[0002] A thermostat refers to a series of automatic control components that undergo physical deformation inside the switch according to temperature changes in the working environment, thereby producing certain special effects and causing conduction or disconnection actions. It is also called a temperature control switch, temperature protector, temperature controller, or simply a thermostat.

[0003] A thermostat usually consists of two parts: a shell and a circuit board. A control switch and a temperature sensor are installed on the circuit board. The temperature probes of the control switch and the temperature sensor extend from the shell. Since the control switch and the temperature sensor are soldered to the circuit board before the circuit board is assembled in the shell, the control switch and the temperature probe extend from the inside of the shell during assembly. However, in this case, the inner space of the shell needs to be set larger to ensure that there is enough space for the control switch and the temperature probe to extend from the inside of the shell. This undoubtedly increases the appearance of the thermostat, cannot meet the needs of users, and brings troubles to manufacturers and users. Utility Model Content
