Problems solved by technology
However, there are defects in this technical solution in use: 1. The knob is only pressed against the housing by the spring on the adjustment rod, so when the knob is accidentally subjected to a pulling force against the housing, the knob will move back to the housing, and at the same time The spring will pull the adjustment rod to move back to the temperature controller synchronously, which will affect the temperature adjustment of the temperature controller by the knob assembly; The elastic force after deformation cannot be greater than the force required for the deformation of the mounting plate, otherwise, under the action of the spring force, the mounting plate in the temperature controller will be deformed, and at the same time, the performance parameters of the spring and the mounting plate will change as the use time increases , it will still cause the problem of deformation of the mounting plate, so the stability is not high; 3. The knob is against the shell, which brings inconvenience to the rotation of the knob

Embodiment Construction
[0020] combine Figure 1 to Figure 2 The knob assembly of the electric appliance thermostat coupler of the present invention will be further described.
[0021] A knob assembly of an electric appliance thermostat coupler is characterized in that it includes a knob 1 and an adjustment rod 3 . The lower end of the knob 1 has at least two connecting pins 2, and the specific number of connecting pins 2 can be set according to actual needs, which can be two, three or four, etc. In this embodiment, the connecting pins 2 are set There are two. The two connecting feet 2 are separated and symmetrically arranged to form a guide groove 25 between the two connecting feet 2, and each of the lower ends of the connecting feet 2 is formed with an outer barb 21, through which the outer barb 21 can make the knob 1 The hook is held on the mounting hole of the housing. The upper side body 31 of the adjusting rod 3 can move in the guide groove 25 in the circumferential limit axial direction. Th...

The invention discloses a knob assembly of an electric appliance temperature adjusting coupler. The knob assembly is characterized in that the knob assembly comprises a knob and an adjusting rod; at least two connecting pins are arranged at the lower end of the knob, the connecting pins are arranged at intervals so as to form a guide groove between the connecting pins, and an outer barb is formed at the lower end of each connecting pin; and the upper side rod body part of the adjusting rod is limited in the circumferential direction and can be movably matched in the guide groove in the axial direction, and a threaded section is arranged on the lower side rod body of the adjusting rod. According to the invention, a stable control effect on a temperature controller can be achieved.
Description
technical field [0001] The invention relates to the field of electric appliance temperature control, in particular to a knob assembly of an electric appliance temperature regulation coupler. Background technique [0002] With the improvement of living standards, people have more and more choices in diet, and in order to bring different diets into every family, there have been a lot of simple hot pots, frying pans and baking pans. During the operation of the equipment, in order to make the food reach the most ideal eating temperature, it will be matched with a thermostat, and the thermostat coupler is used in many electrical appliances because of its convenient operation and high safety performance. [0003] The structure of the thermostat coupler includes a housing, a temperature controller set in the housing and a knob assembly for adjusting the temperature controller. The knob assembly is composed of a knob and an adjustment rod. The knob is located outside the housing, an...
