As a preferred embodiment, in order to facilitate viewing of the display module, the present embodiment preferably adopts a display module following display mode, as shown in fig. 2, the body 11 includes a knob cap 111 and a cap shaft 112 connected with the knob cap 111, a knob cavity is provided in the knob cap 111, a shaft hole 112a is provided in the cap shaft 112 along an axial direction thereof, the knob cavity is communicated with the shaft hole 112a, the display module 13 is disposed in the knob cavity, and the display module 13 is fixedly connected with the base 12 through a connecting shaft 15. When the display module is assembled on the control panel 16, the control panel 16 is provided with an assembly hole with the diameter not smaller than that of the cap shaft 112 and not larger than that of the knob cap 111, the cap shaft 112 penetrates through the assembly hole, the knob cap 111 is positioned on the outer side of the control panel 16, the base 12 is positioned on the inner side of the control panel 16, the base 12 is fixed on a fixed structure on the inner side of the control panel 16, and the body 11 can rotate around the center of the base 12 relative to the base 12, so that selection and switching of different functions are realized, and convenience in operation and display are realized.
The knob cap 111 includes a front case 1111 and a rear case 1112, the front case 1111 is made of a transparent material, and as shown in fig. 2, since the section of the body 1 is in a T-shaped structure, for convenience in assembling the display module 13 in the knob cavity, it is preferable that the front case 1111 is detachably connected to the rear case 1112, the front case 1111 is detached when assembling the display module 13, the display module 13 is inserted into the knob cavity from the front end of the knob cavity, and then the front case 1111 is fastened to the rear case 1112.
The cap shaft 112 is assembled on the control panel through an assembly hole formed on the control panel 16, one or more hall sensing elements 17 are fixed to the outer circumference of the cap shaft 112, one or more first magnets 18 are fixed to the inner circumference of the assembly hole, and the hall sensing elements 17 are matched with the first magnets 18 to sense the rotation position of the knob cap 111. The body 11 is rotatable relative to the base 12 for switching different control programs, one or more hall detection elements 17 can be arranged according to actual needs, and one or more first magnets 18 can also be arranged, when the hall detection elements 17 rotate to be opposite to the first magnets 18, the hall detection elements 17 can generate detection signals and send the detection signals to the control module, and the control module judges the current rotating position of the knob.
Because the body 11 rotates, compare with the control panel 16 or the base 12 of stationary, the motion of both is relative, consequently, can also fix first magnet at the periphery of cap axle, the mode of hall detection element fixing at the interior circumference of pilot hole for detect the rotation position of knob, that is, the still other scheme of hall detection is: one or more first magnets are fixed on the outer circumference of the cap shaft, one or more Hall detection elements are fixed on the inner circumference of the assembly hole, and the Hall detection elements are matched with the first magnets and used for detecting the rotating position of the knob cap.
In order to prevent the assembled knob from being pulled out from the assembly hole entirely or partially by an external force, the free end of the cap shaft 112 is formed with a limiting plate 113, the limiting plate 113 extends to the circumferential outside of the cap shaft 112, and after being assembled with the control panel 16, the limiting plate 113 is positioned at the inner side of the control panel 16, and the limiting plate 113 plays a role of limiting stop by being matched with the knob cap 111, and the control panel wall around the assembly hole is limited between the limiting plate 113 and the knob cap 111.
