When a user operates the device through the magnetic manipulation button 2000, the magnetic touch circuit 1100 in the magnetic touch panel 1000 senses the manipulation of the magnetic manipulation button 2000 to generate a corresponding sensing value, and then performs a specific operation according to the corresponding sensing value. Specifically, as shown in fig. 1, the magnetic attraction touch circuit 1100 includes: a sensing electrode 1110, a sensing unit 1120, and a main control unit 1130.

The number of the sensing electrodes 1110 is plural, and the sensing electrodes are respectively used for sensing the operation of the magnetic attraction operation button 2000 to generate corresponding sensing values; the detecting sensing unit 1120 is respectively connected to the sensing electrodes 1110 to detect sensing values of the sensing electrodes 1110 to obtain corresponding control sensing information; the main control unit 1130 is connected to the detection sensing unit 1120 to receive the manipulation sensing information, so as to perform a corresponding operation according to the manipulation sensing information.

The number of the sensing electrodes 1110 may be 2, 8 or more, and the sensing electrodes 1110 may be specifically an ITO film (indium tin oxide film) or a metal spring, and when a user operates the device by operating the magnetic attraction control button 2000, the sensing electrodes 1110 generate corresponding sensing values.

As shown in fig. 3, in one embodiment, the magnetic control knob 2000 includes: the magnetic device comprises a second magnetic element 2100, a housing 2200 surrounding the second magnetic element 2100, and an intermediate layer 2300 arranged between the second magnetic element 2100 and the housing 2200, wherein an induction block 2210 is protruded on the inner wall of the housing 2200, and the induction block 2210 is connected with the housing 2200.

Under the operation of the user, when the sensing block 2210 moves to the vicinity of a certain sensing electrode 1110, the capacitance effect of the sensing electrode 1110 is obvious. Therefore, when the user operates the magnetic manipulation button 2000, the state of the sensing block 2210 is changed, so that the plurality of sensing electrodes 1110 generate corresponding sensing values according to the state of the sensing block 2210.

The housing 2200 and the sensing block 2210 can be integrally formed, or can be separately and detachably connected to each other.

With reference to fig. 1, after the sensing electrodes 1110 generate corresponding sensing values, the detecting sensing unit 1120 obtains corresponding control sensing information according to the sensing values. Specifically, the detecting and sensing unit 1120 acquires corresponding control sensing information according to a preset relation, the control sensing information can reflect the change of the state of the magnetic control button 2000, so as to obtain the current operation of the user, and then the detecting and sensing unit 1120 sends the control sensing information to the main control unit 1130.

After receiving the control sensing information, the main control unit 1130 performs a corresponding operation, specifically, the control device performs a corresponding operation. The main control unit 1130 is a core unit of the magnetic touch panel 1000, and receives various control information, which is not only the control sensing information obtained by the sensing unit 1120, but also executes corresponding operations to control the operation of the device.

In the embodiment, after the plurality of sensing electrodes 1110 generate corresponding sensing values, the sensing unit 1120 first obtains corresponding control sensing information according to the sensing values, and then the main control unit 1130 performs corresponding operations according to the control sensing information, that is, a part of tasks originally executed by the main control unit in the prior art is shared with the sensing unit 1120, so that on one hand, the task processing amount of the main control unit 1130 can be reduced, and the system confusion caused by untimely task processing of the main control unit 1130 is avoided, on the other hand, the sensing unit 1120 can only process the sensing values generated by the plurality of sensing electrodes 1110, the volume of the sensing unit can be made smaller, and the sensing unit can be arranged adjacent to the plurality of sensing electrodes 1110 during the layout, so that the signal distortion caused by wire resistance and other reasons during the transmission process of the sensing values generated by the plurality of sensing electrodes 1110 can be avoided, i.e. the interference of external factors on the signal transmission can be reduced.

In this embodiment, the distance between the detecting sensor unit 1120 and each of the sensing electrodes 1110 is not more than 50 mm.

Specifically, the distance between the detecting sensing unit 1120 and each sensing electrode 1110 may be the same or different, but the distance is not more than 50 mm, for example, 30 mm, 40 mm or 50 mm.

Specifically, the moving direction of the magnetically attractive manipulation knob 2000 includes a forward movement and a reverse movement, which represent the direction of adjustment. In one application scenario, when the magnetic control knob 2000 is used to adjust the speed of the device, for example, to adjust the grinding speed of the wall breaking machine, the main control unit 1130 determines whether to increase the speed or decrease the speed according to whether the magnetic control knob 2000 is moved in the forward direction or in the reverse direction, and in another application scenario, when the magnetic control knob 2000 is used to adjust the temperature of the device, for example, to adjust the heating temperature of the wall breaking machine, the main control unit 1130 determines whether to increase the temperature or decrease the temperature according to whether the magnetic control knob 2000 is moved in the forward direction or in the reverse direction.

The moving speed of the magnetic control knob 2000 represents the adjusting range, and in an application scenario, the faster the moving speed of the magnetic control knob 2000 is, the larger the adjusting range is, the slower the moving speed is, the smaller the adjusting range is. For example, the set moving speed is divided into three gears, which are: fast, medium, slow, when the induction block 2210 in the magnetic control knob 2000 moves the same distance, if the moving speed of the magnetic control knob 2000 is a fast gear, it indicates that three gears need to be adjusted, if the moving speed of the magnetic control knob 2000 is a medium gear, it indicates that two gears need to be adjusted, and if the moving speed of the magnetic control knob 2000 is a slow gear, it indicates that one gear needs to be adjusted.

The position information of the sensing block 2210 can represent a target gear or a target function, and can also be used to help obtain the moving direction and the moving speed of the magnetic control knob 2000.

In an application scenario, the sensing electrode 1110 corresponding to the sensing block 2210 is the sensing electrode 1110 closest to the sensing block 2210. At this time, when the user wants to adjust the shift or function, the magnetic manipulation knob 2000 can be manipulated to move the sensing block 2210 to the vicinity of the sensing electrode 1110 representing the target shift or function.

When the position information of the sensing block 2210 is used to help obtain the moving direction and the moving speed of the magnetic attraction control button 2000, the position information of the sensing block 2210 includes the start position information and the end position information of the sensing block 2210 when the magnetic attraction control button 2000 performs the control.

Specifically, it can be determined whether the magnetic manipulation button 2000 moves in the forward direction or in the reverse direction according to the start position information and the end position information of the sensing block 2210; according to the initial position information and the final position information of the sensing block 2210 and the movement time of the sensing block 2210, the movement speed of the magnetic control knob 2000 can be obtained.

In this embodiment, the plurality of sensing electrodes 1110 are arranged in a predetermined shape according to the first magnetic member 1300, wherein the first magnetic member 1300 is used for attracting the magnetic control button 2000.

Specifically, the plurality of sensing electrodes 1110 are arranged in a predetermined shape according to the first magnetic member 1300, so as to ensure a compact structure of the magnetic touch panel 1000.

In another application scenario, as shown in fig. 5, the first magnetic element 1300 is a bar shape, and the plurality of sensing electrodes 1110 are arranged in a straight line B along the extending direction of the first magnetic element 1300. At this time, corresponding to the shape of the arrangement of the plurality of sensing electrodes 1110, the motion track of the sensing block 2210 is a straight line, specifically, different from the application scenario of fig. 4, when the user wants to operate the device, the user does not rotate the magnetic attraction control knob 2000 any more, but slides the magnetic attraction control knob 2000.
