All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Referring to fig. 1 and 2, a schematic structural diagram and an exploded view of a knob controller in a natural state according to an embodiment of the present application are shown, including:

A main body 1. A rotatable rear case 2 mounted at one end of the main body 1.

The main body 1 is provided with a first magnet 3 and a second magnet 4; the rear housing 2 houses a third magnet 5 and a fourth magnet 6.

The first magnet 3 faces the third magnet 5, the first magnet 3 is opposite to the third magnet 5 in opposite polarity, the second magnet 4 faces the fourth magnet 6, and the second magnet 4 is opposite to the fourth magnet 6 in opposite polarity.

The polarity of the first magnet 3 is different from the polarity of the second magnet 4.

In the present embodiment, since the first magnet 3 and the second magnet 4 have different polarities, the first magnet 3 and the fourth magnet 6 have the same polarity, and the second magnet 4 and the third magnet 5 have the same polarity. When the rear shell 2 is rotated, the third magnet 5 and the fourth magnet 6 rotate along with the rear shell 2, at this time, the third magnet 5 and the first magnet 3 attract each other and repel each other with the second magnet 4, and the fourth magnet 6 and the second magnet 4 attract each other and repel each other with the first magnet 3, so that when the rotated rear shell 2 has no external force, the initial position is restored through the polarity relationship between the magnets.

in this embodiment, the magnets are all strong magnets, ensuring the resetting effect of the back shell 2.

In this embodiment, one end of the body 1 is provided with a first recess 7 for receiving the first magnet 3 and a second recess 8 for receiving the second magnet 4. The rear housing 2 has a third recess 9 for the third magnet 5 and a fourth recess 10 for the fourth magnet 6.

In this embodiment, when the rear case 2 is rotated, the PCB 16 detects a magnetic induction signal between the magnets through the hall sensor 15, and then determines a rotation direction of the rear case 2 according to the magnetic induction signal, so as to generate a corresponding output signal according to the rotation direction of the rear case 2, and transmit the output signal to the external device through the PCB connection line 19, so that the external device performs a subsequent operation according to the output signal, thereby implementing one-key control on the external device.

preferably, the external device is an intelligent toilet bowl, and the knob controller is arranged on the intelligent toilet bowl. When a user sits on the intelligent toilet to use the knob controller positioned at the right hand side, if the PCB 16 judges that the rear shell 2 rotates leftwards, the intelligent toilet is triggered to execute the woman washing function through the PCB connecting line 19; if the PCB 16 judges that the rear shell 2 rotates rightwards, the intelligent toilet bowl is triggered to execute the hip washing function through the PCB connecting line 19.

It should be noted that the determination of the rotation direction by the PCB 16 according to the magnetic induction signal is a common technical means for those skilled in the art, and is not described herein.

In this embodiment, a pressure sensor is further disposed on the PCB 16 to detect a pressing force of the user on the rear case 2, so as to generate a corresponding control signal according to the pressing force, and transmit the control signal to an external device through the PCB connection line 19.

It should be noted that the PCB 16 generates the corresponding control signal according to the pressing force degree by a common technical means of those skilled in the art, and details thereof are omitted here.
