[0038] It is understandable that the present application does not specifically limit the fixing method of the decorative member 4. For example, in some other embodiments, the decorative member 4 can also be fixed to the top plate 31 by means of threaded connection, magnetic attraction, etc.

[0039] See also Figure 2-5 In some embodiments, the knob assembly 1000 further includes an elastic sealing ring 5, which is sleeved on the connecting column 32, the first end of the elastic sealing ring 5 abuts against the surface of the top plate 31 facing the connecting column 32, and the second end of the elastic sealing ring 5 abuts against the surface of the base 2 facing the top plate 31, and the elastic sealing ring 5 seals the gap between the connecting column 32 and the mounting hole 2b to prevent external water and dust from entering the accommodating cavity 2a through the gap between the connecting column 32 and the mounting hole 2b. The elastic sealing ring 5 is made of elastic material, which can better fit the sealing surface to form a tight seal, and the elastic material can quickly return to its original state after being compressed, which is conducive to maintaining good sealing performance.

[0040] In some embodiments, the elastic sealing ring 5 includes but is not limited to being made of fluororubber (FKM), ethylene propylene diene monomer (EPDM), silicone rubber (VMQ), nitrile rubber (NBR) or chloroprene rubber (CR).

[0041] In some embodiments, the knob assembly 1000 further includes a button 6, which is disposed in the accommodating cavity 2a, and the connecting column 32 can reciprocate in the mounting hole 2b along the axial direction of the mounting hole 2b, and the connecting column 32 is aligned with the button 6 along the axial direction of the mounting hole 2b.

[0043] See also Figure 3 and Figure 6 In some embodiments, a plurality of guide protrusions 22 are provided in the mounting hole 2b, and the plurality of guide protrusions 22 are provided at equal intervals on the inner wall of the mounting hole 2b along the circumferential direction of the axis of the mounting hole 2b, and one end of the plurality of guide protrusions 22 away from the inner wall of the mounting hole 2b abuts against the outer peripheral wall of the connecting column 32. The plurality of guide protrusions 22 are used to guide the connecting column 32 to slide along the axis direction of the mounting hole 2b. Compared with the arrangement mode in which the connecting column 32 directly slides in the mounting hole 2b, the guide protrusions 22 can reduce the contact area between the connecting column 32 and the inner wall of the mounting hole 2b, thereby reducing the resistance of the connecting column 32 sliding in the mounting hole 2b.

[0044] See also Figure 2 and Figure 3 In some embodiments, a hook 321 is provided at one end of the connecting column 32 away from the top plate 31.

[0045] In some embodiments, the surface of the hook head 3211 of the hook 321 facing away from the accommodating cavity 2a is pressed against the step surface 23 under the elastic force generated by the elastic sealing ring 5. The hook 321 cooperates with the top plate 31, and when the knob device is not subjected to external force, the elastic sealing ring 5 is in a preset compression state, and the elastic sealing ring 5 can provide elastic force so that the first end and the second end of the elastic sealing ring 5 are respectively better fitted to the surface of the top plate 31 facing the connecting column 32 and the surface of the base 2 facing the top plate 31, so as to achieve a better sealing effect in a static state.

[0046] In some embodiments, a snap-in groove 2c is provided on the inner wall of the mounting hole 2b, the hook head 3211 of the hook 321 is snap-into the snap-in groove 2c, and the step surface 23 is located on the wall of the snap-in groove 2c facing the accommodating cavity 2a.

[0047] In some embodiments, there are two engaging grooves 2c, which are arranged opposite to each other. There are two hooks 321, which are arranged opposite to each other on both sides of the connecting column 32. One hook 321 is engaged with one engaging groove 2c.

[0048] See also Figure 3-6 In some embodiments, the elastic sealing ring 5 includes a bottom 51 and a bending portion 52, one end 521 of the bending portion 52 is connected to the bottom 51, the bottom 51 abuts against the surface of the base 2 facing the top plate 31, and the other end 522 of the bending portion 52 is inclined in the direction toward the connecting column 32, and the other end 522 of the bending portion 52 abuts against the surface of the base 2 facing the top plate 31. The bending portion 52 can be bent in the direction X from the connecting column 32 to the key 6 under the push of the top plate 31, and rebound in the direction from the key 6 to the connecting column 32 after the thrust applied by the top plate 31 is removed, so that the elastic sealing ring 5 can be made of a material with a relatively high hardness, and has good elasticity in the direction X from the connecting column 32 to the key 6 and in the direction from the key 6 to the connecting column 32 while meeting the overall strength.

[0049] In some embodiments, the other end 522 of the bending portion 52 includes an annular top surface 5221 and an annular inner wall surface 5222 , the annular top surface 5221 is attached to the surface of the base 2 facing the top plate 31 , and the annular inner wall surface 5222 is attached to the outer peripheral wall of the connecting column 32 .

[0050] In some embodiments, an annular groove 2d is provided at one end of the base 2 facing the top plate 31, the bottom 51 is at least partially provided in the annular groove 2d, the bottom surface 511 of the base 2 abuts against the groove bottom 24 of the annular groove 2d, the inner peripheral wall 512 of the bottom 51 abuts against the inner groove wall 25 of the annular groove 2d, and the outer peripheral wall 513 of the bottom 51 abuts against the outer groove wall 26 of the annular groove 2d.

[0051] See also Figure 1 and Figure 3 In some embodiments, the window 1a is trumpet-shaped, and the cross-sectional area of ​​the window 1a gradually decreases along the direction from the knob cover 1 to the base 2. The decorative member 4 is located in the window 1a, wherein the cross-sectional area of ​​the window 1a is a cross-sectional area along a direction perpendicular to the knob cover 1 to the base 2.

[0052] In some embodiments, the main body 41 of the decorative element 4 is in the shape of a circular sheet, and the inner side wall 12 of the window 1a encloses and forms a space in the shape of an inverted truncated cone.

[0053] See also Figure 3 In some embodiments, the knob assembly 1000 further includes a light emitting member 7, which is disposed in the base 2 and is used to emit light toward the window 1a. The base 2 and the fixing bracket 3 are at least partially made of a light-transmitting material, and the parts of the base 2 and the fixing bracket 3 made of a light-transmitting material are used to allow the light generated by the light emitting member 7 to pass through. There is a preset gap a between the decorative member 4 and the inner side wall 12 of the window 1a, and the preset gap a is used to allow the light generated by the light emitting member 7 to pass through. After the light emitted by the light emitting member 7 passes through the light-transmitting parts of the base 2 and the fixing bracket 3, it reaches the inner side wall 12 of the window 1a after reflection, and is finally transmitted to the outside of the window 1a through the preset gap a between the decorative member 4 and the inner side wall 12 of the window 1a. Since the light generated by the light emitting member 7 is not emitted through the window 1a in a straight line, but is diffusely reflected on the surfaces of various objects during the transmission process, a softer and more uniform lighting effect can be finally presented at the window 1a.

[0054] In some embodiments, the knob assembly 1000 includes a circuit board 8, and the circuit board 8 is disposed in the accommodating cavity 2a.

[0055] In some embodiments, the light-emitting element 7 is a lamp bead, which is disposed on a surface of the circuit board 8 facing the window 1 a , and is electrically connected to the circuit board 8 .

[0056] In some embodiments, there are multiple lamp beads, and the multiple lamp beads are arranged around the central axis of the window 1a.

[0057] See also Figure 2 and Figure 3 In some embodiments, the knob assembly 1000 includes a magnetic body 9 and a magnetic sensing element (not shown), wherein the magnetic body 9 is disposed on the knob cover 1, and the magnetic sensing element is disposed on the circuit board 8. When the knob cover 1 rotates relative to the base 2, the magnetic sensing element senses the position change of the magnetic body 9 to generate a sensing signal.

[0058] In some embodiments, the magnetic body 9 is annular, and the central axis of the magnetic body 9 coincides with the rotation axis of the knob cover 1 relative to the base 2. The magnetic body 9 includes sixteen equal magnetic poles, and the N poles and the S poles in the sixteen equal magnetic poles are alternately arranged in sequence along the direction of the rotation axis of the knob cover 1 relative to the base 2. The magnetic sensing element is a Hall sensor, and the number of the Hall sensors is two. When the magnetic body 9 rotates with the knob cover 1, the two Hall sensors are used to sense the changes in the magnetic field generated when the magnetic body 9 rotates. When the knob cover 1 rotates and drives the magnetic body 9 to rotate around the rotation axis of the knob cover 1, the alternating magnetic poles with opposite polarities approach and move away from the magnetic sensing element in sequence, so that the magnetic sensing element can obtain a periodic waveform for determining the rotation direction of the knob cover 1.

[0059] It is understandable that the magnetic body 9 is not limited to the sixteen equal poles mentioned above. For example, in some other embodiments, the magnetic body 9 can also be thirty-two equal poles. Along the direction of the rotation axis around the knob cover 1, the number of magnetic poles of the magnetic body 9 can be selected according to actual conditions.

[0060] In some embodiments, the magnetic body 9 is a permanent magnet.

[0061] See also Figure 7 and Figure 8 In some embodiments, a plurality of protruding teeth 13 are provided on the surface of the knob cover 1 facing the base 2, and the plurality of protruding teeth 13 are arranged at equal intervals along the circumferential direction of the rotation axis of the knob cover 1. A spring sheet 27 is provided at one end of the base 2 close to the knob cover 1, and the spring sheet 27 is bent toward the knob cover 1 to form a protruding portion 271. When the knob cover 1 rotates relative to the base 2, the plurality of protruding teeth 13 can move along the direction of the rotation axis around the knob cover 1 and squeeze the protruding portion 271, so as to sequentially pass over the protruding portion 271 after the protruding portion 271 is elastically deformed. The resistance provided by the protruding portion 271 enables the operator to feel an intermittent sense of resistance when turning the knob cover 1, and the protruding portion 271 can play a certain limiting role on the knob cover 1 to prevent the knob cover 1 from rotating by itself.

[0062] In some embodiments, the spring piece 27 includes a first mounting portion 272 and a second mounting portion 273 respectively connected to both ends of the protrusion 271. A protrusion 28 is provided on the side wall of the base 2 at one end close to the knob cover 1, and the protrusion 28 is provided with a slide groove (not shown) that penetrates the protrusion 28 along the direction from the knob cover 1 to the base 2. The first mounting portion 272 and the second mounting portion 273 are respectively fixed to the base 2, and the protrusion 271 is penetrated in the slide groove along the direction from the base 2 to the knob cover 1. When the protruding tooth 13 moves in the direction of the rotation axis around the knob cover 1 and squeezes the protrusion 271, the protruding tooth 13 forces the protrusion 271 to retract into the slide groove along the direction from the knob cover 1 to the base 2. After the protruding tooth 13 passes over the protruding portion 271, the protrusion 271 rebounds along the direction from the base 2 to the knob cover 1 and extends out of the slide groove.

[0063] It is understandable that one or more spring pieces 27 can be provided according to actual needs. Exemplarily, in some embodiments, the number of spring pieces 27 is two, and the two spring pieces 27 are respectively provided on two opposite sides of the base 2 .

[0064] Based on the same inventive concept, an embodiment of the present application also provides a toilet, including the knob assembly 1000 in any of the above embodiments.

[0065] The above descriptions are merely embodiments of the present application and are not intended to limit the patent scope of the present application.
