a third conductive member 121 is arranged on the rotary disc 12, and the rotary disc 12 is linked with the valve rod 3 of the knob 4 to drive the third conductive member 121 to rotate;

when the third conductive member 121 contacts the first conductive member 131 and any one of the second conductive members 132, the detection circuit is turned on, the controller 10 is turned on through the corresponding interface 101, and the rotation angle of the valve rod 3 corresponding to the knob 4 is obtained according to the turned-on interface 101;

specifically, as shown in fig. 2 and fig. 3, the detection apparatus for the rotation angle of the knob is applied to a kitchen range, the rotary disk 12 is fixedly connected to the valve rod 3 of the knob 4, when a user uses the knob 4, the rotary disk 12 can synchronously rotate through the valve rod 3, the third conductive piece 121 is driven by the rotary disk 12 to move along the first conductive piece 131, in the rotating process of the rotary disk 12, the third conductive piece 121 is respectively contacted with the second conductive piece 132 at a corresponding angle, and the circuit of the controller interface 101 corresponding to the second conductive piece 132 is turned on, and the controller 10 obtains the rotation angle of the knob 4 according to the turned-on interface 101.
