Speed adjusting circuit of egg beater, speed adjusting method and egg beater

Abstract

The invention discloses a speed adjusting circuit of an egg beater, a speed adjusting method and an egg beater. The speed adjusting circuit is accessed into a control circuit of an egg beater, is usedfor adjusting the speed of a motor and comprises co-polar switches, a bidirectional thyristor, a triggering circuit and a charge circuit, wherein the co-polar switches comprise a first switch and a second switch with a shared end; the shared end and the bidirectional thyristor are electrically connected with the charge circuit. The speed adjusting circuit disclosed by the invention is simple in circuit structure, low-cost stepless speed adjustment of a motor is achieved, in addition, due to knob speed adjustment, rotation speeds of different shifts can be uniformly changed.

Description

technical field [0001] The invention relates to kitchen supplies, in particular to a speed regulating circuit, a speed regulating method and an egg beater of an egg beater. Background technique [0002] At present, the speed regulation of the common egg beater is to draw the speed regulation contact from the coil of the built-in motor of the egg beater, and realize the speed regulation by adjusting the mechanical switch connected to the contact, which not only increases the size and cost of the motor, but also increases the speed. The design difficulty of the overall space of the egg beater. If the speed regulation contact is drawn from the coil of the motor, the speed regulation gear will be limited when the speed regulation is realized through a mechanical switch. Generally, 3 speed regulation is achieved, and it is more difficult to realize 5-6 speed regulation. And the cost will be greatly increased; adopting other simple electronic speed regulation methods, some of the...

Problems solved by technology

If the speed regulation contact is drawn from the coil of the motor, the speed regulation gear will be limited when the speed regulation is realized through a mechanical switch. Generally, 3 speed regulation is achieved, and it is more difficult to realize 5-6 speed regulation. Moreover, the cost will be greatly increased; using other simple electronic speed regulation methods, some of the speeds of each gear have large distinctions, and some have small distinctions, which cannot achieve the ideal effect of uniform speed in stages
