Embodiment Construction

[0034] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0035] The core idea of ​​the present invention is to design a separate rotary switch. The rotary switch is a separate part, which does not have any physical connection with the main control circuit board of the terminal equipment. Two knob switches are installed on the main control circuit board of the terminal equipment. The sensor is used to sense the action of the knob switch (including the forward rotation, reverse rotation, rotation angle and rotation speed of the knob). When the knob switch is sensed, the main control circuit board will respond accordingly.

[0036] Such as Figure 1~3 As shown, the embodiment of the present invention relates to a separate rotary switch, including:

Abstract

The invention discloses a separate knob switch, terminal equipment and a working mode adjusting method of the separate knob switch. The separate knob switch comprises a knob switch and two hall sensors, wherein the knob switch is arranged on a control panel and comprises a rotating disk; a plurality of magnet components are arranged on the rotating disk along the circumference of the rotating disk; and the two hall sensors are arranged on a master control circuit board below the control panel, and are located on the contour edge of a vertical projection of the rotating disk on the master control circuit board. Through a separate design of the knob switch and the hall sensors, a rotating action of the knob switch is sensed by hall electromagnetic induction; the knob is separated from the master control circuit board; an opening design does not need to be carried out on the control panel; and the master control circuit board is completely isolated from the external environment, so that an effective isolating protection is carried out on the master control circuit board; and the knob switch can also be conveniently changed.

Description

technical field [0001] The invention relates to the field of electrical technology, in particular to a separate rotary switch, a terminal device and a method for adjusting its working mode. Background technique [0002] The knob switch on the existing terminal equipment is directly connected with the control computer board by using a mechanical structure. When the knob switch rotates, it will drive the knob control on the computer board to rotate together, and then the computer board will make a processing by detecting the rotation of the knob control . In this way, a circular hole must be opened on the control panel, and the rotary switch needs to protrude to the outside through the circular hole to allow the user to control it, so there must be a gap between the rotary switch and the control panel. When the terminal equipment is used in a relatively humid environment, for example, the terminal equipment is a washing machine or a water heater, the water vapor in the air or...
