The cover includes a ring body and a cover body. The cover body is arranged at the top end of the ring body and blocks the opening at the top end of the ring body. The mounting bracket includes a sleeve ring. The bottom end edge of the sleeve ring extends inwardly and has a mounting ring. The mounting ring is sleeved on the ring body of the cover and is in interference fit with the ring body. The sleeve ring is provided with two ear pieces. Each ear piece is provided with a mounting hole. When the ear pieces are rotated to the required position relative to the terminals, the mounting ring extending inwardly from the bottom end edge of the sleeve ring is sleeved on the ring body of the cover and is in interference fit with the ring body, thereby achieving the relative fixation of the mounting bracket and the cover. The temperature controller bracket and the temperature controller thereof can flexibly adapt to the complex structure inside various electrical appliances, solve the problem of difficulty in adjusting the angle of the ear pieces relative to the terminals during installation, ensure that the temperature controller is not easily rotated during installation, and improve the installation efficiency.

[0003] The above-mentioned temperature controller mounting bracket and temperature controller thereof are only applicable to flat-bottomed pot inner containers and can only be adapted to one type of pot inner container. Therefore, the application range is narrow, and the temperature controller mounting bracket and temperature controller thereof cannot be universally used for flat-bottomed pot inner containers and concave-bottomed pot inner containers.

When the mounting bracket is installed with a sheet, the rivet can be directly riveted with the sheet. The mounting bracket does not need to use screws and can install and fix the temperature controller on the sheet.

[0005] The above-mentioned multipurpose temperature controller mounting bracket and temperature controller thereof are only applicable to flat-bottomed pot inner containers and can only be adapted to one type of pot inner container. Therefore, the application range is narrow, and the temperature controller mounting bracket and temperature controller thereof cannot be universally used for flat-bottomed pot inner containers and concave-bottomed pot inner containers.
