Description

Technical Field

[0002] As we all know, a thermostat is a device used to control temperature, commonly used in various heating or cooling systems. It measures the temperature of the environment or equipment and automatically adjusts the working state of the heating or cooling equipment according to the set temperature range to keep the temperature stable within the set range.

[0003] The Chinese utility model patent with the authorization announcement number CN219873307U discloses a multifunctional thermostat, including a base; a support mechanism for placing the multifunctional thermostat body, the support mechanism including a support seat, both sides of the bottom of the support seat are fixedly connected with support legs, and a heat dissipation fan is installed between the two support legs; a fixing mechanism for fixing the multifunctional thermostat body. The utility model not only adopts an overhead manner to install the multifunctional thermostat body, but also achieves good heat dissipation of the multifunctional thermostat body with the assistance of the heat dissipation fan, avoiding the problem that the internal parts of the thermostat are damaged by heat caused by heat accumulation during the use of the thermostat, thereby causing the thermostat to malfunction and shorten the service life of the thermostat, and by pulling the fixing seat upwards, the fixing seat can be separated from the multifunctional thermostat body, thereby achieving convenient disassembly of the multifunctional thermostat body, which brings great inconvenience to the user. However, the auxiliary heat dissipation structure of the existing thermostat still has certain deficiencies when used. Although its auxiliary heat dissipation structure uses a fan to perform auxiliary heat dissipation treatment on the thermostat body, due to the presence of certain dust and other impurities in the air, it will cause dust adhesion on the fan blades, thereby affecting the heat dissipation effect of the fan.

[0004] Therefore, the existing technology still needs to be improved and developed. Utility Model Content

Through the above structural arrangement, the width of the long rod can be designed as required, so that the contact area between the brush part fixed on the long rod and the filter screen is appropriate, that is, the width of the long rod is not limited by the width of the through slot.

[0012] The cam is an assembly of a plurality of springs, each of which is adapted to engage with the at least one cam portion of the thermostat body and engage with the at least one cam portion of the thermostat body to engage with the at least one cam portion. Through the above-mentioned structural setting, under the action of the first spring, the limit plate and other structures, the plug board can be plugged and limited, so that the mounting shell can be stably fixed together with the thermostat body, and it is also convenient for operators to quickly install and use it.
