Rotation adjusting device, stepless adjusting knob and stepless adjusting method thereof

Abstract

The invention discloses a rotation adjusting device, a stepless adjusting knob and a stepless adjusting method thereof. The rotation adjusting device comprises a circuit board and a position detection switch arranged on the circuit board, wherein a dial disc is rotatably positioned on the circuit board, and is provided with a switch dial block, and the switch dial block triggers the position detection switch. The stepless adjusting knob comprises a shell and a bottom cover, wherein the rotation adjusting device in the technical scheme is packaged in the shell, an operating handle is arranged on the shell in a penetrating mode and used for rotating to drive a dial disc, and a circuit board is arranged on the bottom cover. The invention discloses a stepless regulation method, which comprises the following steps of: rotating a dial disc to drive a switch dial block to trigger a position detection switch, receiving position detection information of the position detection switch through an MCU chip, and correspondingly outputting a working instruction according to the position detection information. According to the invention, a traditional mode is replaced by a mode of triggering the position detection switch through the dial disc, the rotation control mode of the dial up disc is visual, and the device has the advantages of being long in service life and high in adjusting precision.

Description

technical field [0001] The invention relates to the technical field of stepless adjustment switches, in particular to a rotary adjustment device, a stepless adjustment knob and a stepless adjustment method thereof. Background technique [0002] Existing common circuits for stepless temperature regulation or speed regulation generally use potentiometers (rotary or sliding). The purpose of stepless speed regulation and temperature regulation is realized by adjusting the continuous change of the resistance value of the potentiometer. The circuit structure of this adjustment switch is simple and easy to implement, but there are certain disadvantages: frequent rotation or sliding of the potentiometer will cause wear and tear, cause changes in resistance value, cause nonlinear changes and noise interference of the potentiometer, and affect the adjustment accuracy; and Commonly used potentiometers have a limited service life, and some high-demand electrical products cannot meet th...
