Description

Technical Field

[0001] The utility model discloses a torque regulating mechanism for a vegetable washing machine, belonging to the field of vegetable washing machine accessories. Background Art

[0002] Torque is a special moment that makes an object rotate. Under the condition of fixed power, it is inversely proportional to the motor speed. The faster the speed, the smaller the torque, and vice versa. For a vegetable washing machine, a speed knob is often used to adjust the speed of the motor in the vegetable washing machine, so as to achieve the purpose of adjusting the torque of the vegetable washing machine. At present, the relative position between the knob cap in the speed knob and the outer shell of the vegetable washing machine is fixed. When the knob cap is turned, the fingers of the personnel are mostly in contact with the knob cap. When the fingers of the personnel are washed with vegetables and there is a lot of water, they are prone to slipping. Therefore, it is necessary to design a torque adjustment mechanism for a vegetable washing machine that is easy to rotate the knob cap by holding. Utility Model Content
