The center of the rotating hole 5 is collinear with the axis of the valve core rod 2. The rotating member 6 is inserted into the rotating hole 5 and can rotate within the rotating hole 5.

[0043] When installing the above-mentioned handwheel structure, the rotating part 6 is inserted into the rotating hole 5, and the center of the rotating hole 5 is collinear with the axis of the valve core rod 2. This ensures that the valve core rod 2, the display screen 4, and the handwheel 3 are concentric during installation, reducing installation deviations, ensuring installation accuracy, and preventing friction between the handwheel 3 and the display screen 4 during rotation due to installation errors, thus reducing wear on the handwheel 3 or the display screen 4.

[0044] like Figure 1 and Figure 2As shown, in some embodiments, the rotating hole 5 is disposed on the display screen 4, and the rotating component 6 is disposed on the valve core rod 2. The rotating component 6 and the valve core rod 2 are coaxially disposed, so that the rotating component 6 can rotate coaxially with it during the rotation of the valve core rod 2, ensuring that the rotating component 6 rotates coaxially within the rotating hole 5. Specifically, the display screen 4 includes a screen 41 and a screen base 42. The screen 41 can be fixed to the screen base 42 by means of adhesive, snap-fit, fastening, or plugging.

During installation, the snap block 46 can be directly snapped into the snap hole 45 for fixation. The specific shapes of the snap hole 45 and the snap block 46 are not specifically limited. The screen base 42 is fixed to the valve core seat 1, and the rotating hole 5 is provided on the screen base 42, thereby preventing the rotating part 6 from interfering with the core components such as the screen 41 of the display screen 4 during rotation; and the rotating hole 5 is also convenient to process when provided on the screen base 42. In one embodiment, the rotating part 6 is a bolt screwed to the valve core rod 2. Of course, it is understood that, as an equivalent replacement, the bolt can also be replaced by a screw. In an alternative embodiment, the rotating part 6 can also be a rotating rod provided at the second end of the valve core rod 2, and the screw, bolt, and rotating rod rotate in the rotating hole 5.

[0045] like Figure 1 and Figure 2 As shown, to facilitate fixing the screen base 42 to the valve core seat 1 and ensure the stability of the display screen 4, in some embodiments, the valve core seat 1 includes a valve seat 11 and a seat ring 12. The valve seat 11 has an inner cavity, in which a valve core is disposed. The valve core rod 2 extends into the inner cavity to connect to the valve core, and the seat ring 12 is fixed to the valve seat 11. In the current embodiment, the seat ring 12 and the valve seat 11 have mating threads, and the seat ring 12 is screwed onto the valve seat 11, allowing the seat ring 12 to be disassembled. The seat ring 12 is provided with a connecting screw hole 13, and the screen base 42 is provided with a through hole 43. The limiting member 7 passes through the through hole 43 and is screwed onto the connecting screw hole 13, thereby fixing the screen base 42 to the seat ring 12. Exemplarily, the limiting member 7 can be, but is not limited to, a screw or bolt. In the current embodiment, two connecting screw holes 13 are provided.

[0046] Furthermore, a first fixing post 14 is provided on the seat ring 12, and a connecting screw hole 13 is provided at the end of the first fixing post 14 away from the seat ring 12. A second fixing post 44 is provided on the screen base 42, and a through hole 43 extends axially along the second fixing post 44 and is provided on the second fixing post 44. The first fixing post 14 can be inserted into the through hole 43, thereby facilitating the fixing of the screen base 42 and the seat ring 12. It is understood that in some alternative embodiments, the through hole 43 can also be provided on the first fixing post 14, and the second fixing post 44 can be inserted into the through hole 43, while the connecting screw hole 13 is still provided on the first fixing post 14.

[0047] like Figure 3 As shown, in order to drive the valve core rod 2 to rotate when the handwheel 3 is turned, in some embodiments, the inner wall of the through cavity 31 of the handwheel 3 is provided with a connecting protrusion 32, the connecting protrusion 32 is provided with a connecting hole 33, the connecting hole 33 is concentric with the rotating hole 5, a first meshing tooth 34 is provided in the connecting hole 33, and a second meshing tooth 21 is provided at the second end of the valve core rod 2. When the valve core rod 2 is inserted into the connecting hole 33, the first meshing tooth 34 and the second meshing tooth 21 mesh, thereby driving the valve core rod 2 to rotate when the handwheel 3 is turned, and keeping the valve core rod 2, the display screen 4 and the handwheel 3 concentric. In the current embodiment, the first fixing post 14 and the second fixing post 44 are provided in the gap between the connecting protrusion 32 and the cavity wall of the through cavity 31 to avoid interference between the handwheel 3 and the first fixing post 14 and the second fixing post 44 when the handwheel 3 is turned; in addition, the connecting wire of the display screen 4 can also pass through the above-mentioned gap.

[0048] like Figure 1 and Figure 2 As shown, in some embodiments, the seat ring 12 has a plurality of abutting protrusions 15 on the side facing the display screen 4. The plurality of abutting protrusions 15 are distributed along the circumference of the seat ring 12. An elastic member 8 is provided on the connecting protrusion 32 of the seat ring 12. The end of the elastic member 8 is connected to an abutting head 9. The abutting head 9 abuts against the abutting protrusion 15. Thus, during the rotation of the handwheel 3, the abutting head 9 moves along the circumference of the seat ring 12, thereby causing the abutting protrusion 15 to press against the abutting head 9 and squeeze the elastic member 8. When the abutting protrusion 15 disengages from the abutting head 9, the elastic member 8 is released. During this process, vibration and sound can be fed back, and rotational feedback can be formed during the rotation of the handwheel 3.

[0049] This application also provides a faucet, which includes the above-described handwheel structure to prevent the handwheel 3 from rubbing against the display screen 4 during rotation.
