[0025] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0026] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0027] In the present invention, unless otherwise specified, directional words such as "up, down, top, bottom" are usually used with reference to the directions shown in the drawings, or with reference to the components themselves in the vertical, perpendicular or gravity direction; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above directional words are not used to limit the present invention.

[0028] Obviously, the embodiments described above are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0029] In order to solve the problem that the toilet knob in the prior art cannot meet the multi-functional requirements, the present invention provides a knob mechanism and a toilet. Among them, the toilet described below includes the following knob mechanism.

[0030] like Figures 1 to 6As shown, the knob mechanism includes a fixed base assembly 10, a rotating knob cover 20, a status detection member 30, a gear detection member 40 and a trigger member 50. The fixed base assembly 10 is arranged at the position to be installed. The rotating knob cover 20 is movably arranged on the fixed base assembly 10, and the rotating knob cover 20 can move along the axial direction of the fixed base assembly 10 and is rotatably arranged relative to the fixed base assembly 10. The gear detection member 40 and the status detection member 30 are jointly arranged on one of the fixed base assembly 10 or the rotating knob cover 20. The trigger member 50 is arranged on the other of the fixed base assembly 10 or the rotating knob cover 20, wherein the status detection member 30 is used to detect the axial position state of the rotating knob cover 20, and the gear detection member 40 is used to detect the trigger gear of the rotating knob cover 20 in the current axial position state.

[0031] By setting a status detection member 30, when the rotary knob cover 20 is not extended, when the status detection member 30 detects the trigger member 50 on the rotary knob cover 20, the rotary knob cover 20 is rotated, and the trigger member 50 is used to trigger the gear detection member 40 to complete the triggering of the gear corresponding function, and then the rotary knob cover 20 is reset. After resetting, the rotary knob cover 20 is moved in a direction away from the fixed seat assembly 10 to achieve the extension of the rotary knob cover 20. At this time, the status detection member 30 cannot detect the trigger member 50, and the rotary knob cover 20 is rotated again to achieve the trigger member 50 triggering the gear detection member 40 again to achieve the triggering of the corresponding gear. Since the trigger member 50 cannot trigger the status detection member 30 at this time, it is determined that the rotary knob cover 20 has been extended, thereby switching the function corresponding to the same gear. Compared with the traditional technical solution of only rotating to trigger the corresponding function, the present application can change the distance between the rotary knob cover 20 and the fixed seat assembly 10, and finally achieve the increase of the functions that the knob mechanism can achieve, meeting the needs of multi-functions.

[0032] In this embodiment, the status detection component 30 and the gear detection component 40 are Hall elements, and the trigger component 50 is a magnetic element. When the rotary knob cover 20 moves along the axial direction of the fixed base assembly 10 away from the fixed base assembly 10, the trigger component 50 cannot trigger the status detection component 30.

[0033] Specifically, the trigger member 50 is realized by rotating the rotary knob cover 20. When the trigger member 50 approaches the gear detection member 40, the gear detection member 40 can generate a signal when detecting that the trigger member 50 approaches. When the trigger member 50 is away from the status detection member 30, the two will also generate a signal when they approach each other. Since the distance between the two is large, the generated signal exceeds the signal preset value of the status detection member 30, and thus the status detection member 30 cannot be triggered.

[0034] like Figure 1 、 Figures 4 and 5 As shown, the fixing seat assembly 10 includes a circuit board 14 , and the state detection member 30 and the gear position detection member 40 are connected to the circuit board 14 .

[0035] In this embodiment, the state detection member 30 includes at least one Hall element; and / or the gear position detection member 40 includes a plurality of Hall elements spaced apart along the circumference of the fixing seat assembly 10 .

[0036] Specifically, there are three status detection members 30, which are spaced apart on the circuit board 14. There are two gear position detection members 40, which are spaced apart on the circuit board 14. The two status detection members 30 and the two gear position detection members 40 are correspondingly arranged so that when the rotary knob cover 20 is in the retracted state and the trigger member 50 triggers the gear position detection members 40, the status detection members 30 can detect the trigger member 50. The status detection members 30 are arranged in contact with the circuit board 14, and the gear position detection members 40 are arranged perpendicularly and spaced apart from the circuit board 14. The distance between the top surface of the status detection member 30 and the circuit board 14 is less than the distance between the gear position detection member 40 and the circuit board 14.

[0037] like Figures 1 to 3 As shown, the knob mechanism further includes a reset member 60 , which is disposed on one of the fixing seat assembly 10 or the rotary knob cover 20 where the trigger member 50 is not disposed. The reset member 60 is used to reset the rotary knob cover 20 after rotation.

[0038] Specifically, there are two reset members 60 , and the two reset members 60 and the two trigger members 50 are correspondingly provided.

[0039] In this embodiment, the reset member 60 is disposed on the fixing seat assembly 10 , and the trigger member 50 is disposed on the rotating knob cover 20 .

[0040] In this embodiment, the reset member 60 and the trigger member 50 are both magnetic elements, and the length of the trigger member 50 in the axial direction of the rotary knob cover 20 is greater than the length of the reset member 60 in the axial direction of the rotary knob cover 20 .

[0041] Specifically, the reset member 60 and the trigger member 50 are magnetic elements with opposite magnetic properties. With this arrangement, when the rotary knob cover 20 is twisted, the trigger member 50 and the reset member 60 are offset, completing the gear change. Subsequently, when the rotary knob cover 20 is released, the rotary knob cover 20 automatically returns to the corresponding position of the trigger member 50 and the reset member 60 due to the magnetic force between the trigger member 50 and the reset member 60. Furthermore, by setting the length of the trigger member 50 to exceed the length of the reset member 60, the rotary knob cover 20 can still be reset by the magnetic force between the trigger member 50 and the reset member 60 when the rotary knob cover 20 is pulled out and the knob mechanism is in the extended position. Optionally, there is only one trigger member 50, the length of which is greater than the length of the reset member 60. The trigger member 50 is disposed on the rotary knob cover 20 or the fixed base assembly 10, and the corresponding reset member 60 is disposed on the other of the two.

[0042] In this embodiment, both the reset member 60 and the trigger member 50 are magnetic structures, and the trigger member 50 includes a first sub-magnet 51 and a second sub-magnet 52 arranged along the axial direction of the rotary knob cover 20. The axial length of the first sub-magnet 51 in the rotary knob cover 20 is equal to the axial length of the second sub-magnet 52 in the rotary knob cover 20. The axial length of the first sub-magnet 51 in the rotary knob cover 20 is equal to the axial length of the reset member 60 in the rotary knob cover 20.

[0043] Specifically, the first sub-magnet 51, the second sub-magnet 52, and the fixing base assembly 10 are arranged in sequence along the same straight line. When the rotary knob cover 20 is in the retracted state, the first sub-magnet 51 is arranged corresponding to the reset member 60 and can trigger the gear position detection member 40, and the status detection member 30 can detect the second sub-magnet 52. When the rotary knob cover 20 is in the extended state, the status detection member 30 cannot detect the second sub-magnet 52. Rotating the rotary knob cover 20 can trigger the gear position detection member 40 through the second sub-magnet 52.

[0044] In this embodiment, the reset member 60 includes a plurality of magnet structures spaced apart along the circumference of the fixing seat assembly 10 . There are multiple first sub-magnets 51 and second sub-magnets 52 , and the number of the magnet structures is the same as that of the magnet structures.

[0045] Specifically, there are two first sub-magnets 51 and two second sub-magnets 52, and the two first sub-magnets 51 are located on the same straight line. Similarly, the two second sub-magnets 52 are also located on the same straight line, so that the rotating knob cover 20 can trigger the gear change by rotating left or right.

[0046] like Figures 1 to 3 as well as Figure 6 As shown, the knob mechanism further includes a stopper 100, which is connected to the inner wall of the rotary knob cover 20 and at least partially extends out of the rotary knob cover 20. The fixed seat assembly 10 includes a mounting platform 11 and a base 12. The reset member 60 is disposed on the mounting platform 11, and the rotary knob cover 20 is movably disposed on the mounting platform 11. A sliding groove adapted to the stopper 100 is formed on the inner wall of the mounting platform 11. The base 12 is disposed on a side of the mounting platform 11 away from the rotary knob cover 20. A mounting cavity is formed between the base 12 and the mounting platform 11. The status detection member 30 is disposed in the mounting cavity, and at least a portion of the gear position detection member 40 extends from the mounting cavity and is located between the rotary knob cover 20 and the mounting platform 11.

[0047] Specifically, there are two limit members 100, and the two limit members 100 are arranged at intervals. Two spaced-apart sliding grooves are provided on the inner wall of the mounting platform 11. When the rotary knob cover 20 is extended, it is in the extended state, and when the rotary knob cover 20 is not extended, it is in the default state. Through the cooperation of the sliding groove and the limit member 100, it is ensured that the rotary knob cover 20 will not move in the axial direction when rotating, affecting the Hall sensor detection, and providing a damping feel and positioning when the knob is extended and switched to the default state. The rotary knob cover 20 cannot be separated from the mounting platform 11 when rotating. A protruding structure is provided on the mounting platform 11, and the reset member 60 is provided at the top of the protruding structure, and the two reset members 60 are arranged opposite to each other. The base 12 is connected to the mounting platform 11 to form a accommodating cavity for accommodating the circuit board 14. Optionally, the circuit board 14 is detachably connected to the base 12.

[0048] like Figures 1 to 5 As shown, the fixing seat assembly 10 further includes a waterproof member 13, which is disposed between the mounting platform 11 and the base 12 to seal the mounting cavity. A circuit board 14 is accommodated in the mounting cavity.

[0049] Specifically, waterproof member 13 is made of waterproof silicone. The raised structure of mounting platform 11 defines a receiving space, into which waterproof member 13 partially extends. Waterproof member 13 cooperates with base 12 to seal circuit board 14, protecting it as well as the status detector 30 and gear position detector 40 mounted thereon. Waterproof member 13 has a groove facing mounting platform 11 that extends into the receiving space and serves to provide a safe and secure position detector 40.

[0050] like Figures 1 to 3 As shown, the knob mechanism also includes a sealing ring 15, a pressure rod 70, a button 80, and a retaining ring 90. One end of the pressure rod 70 is connected to the inner wall of the rotary knob cover 20, and the other end extends into the receiving space of the raised structure. A retaining ring 90 is provided at one end of the pressure rod 70 within the receiving space to prevent the rotary knob cover 20 from falling off the mounting platform 11. The sealing ring 15 is positioned between the mounting platform 11 and the base 12 to further seal the circuit board 14. The button 80 is mounted on the circuit board 14. Pressing the rotary knob cover 20 activates the pressure rod 70, triggering the button 80 and thus the corresponding function.

[0051] The present application also provides a toilet. The toilet includes the above-mentioned knob mechanism and a toilet body. The knob mechanism is arranged on the toilet body.

[0052] Specifically, the knob mechanism is set on the side of the toilet body. When in use, different functions can be switched by manually turning the knob mechanism to achieve flushing, deodorization, and cleaning. Each gear corresponds to a function.

[0053] From the above description, it can be seen that the above-mentioned embodiments of the present invention achieve the following technical effects: by setting a knob mechanism including a fixed base assembly 10, a rotating knob cover 20, a status detection component 30, a gear detection component 40 and a trigger component 50, the fixed base assembly 10 is arranged at the position to be installed, the rotating knob cover 20 is movably arranged on the fixed base assembly 10, the rotating knob cover 20 can move along the axial direction of the fixed base assembly 10 and is rotatably arranged relative to the fixed base assembly 10, the gear detection component 40 and the status detection component 30 are jointly arranged on one of the fixed base assembly 10 or the rotating knob cover 20, and the trigger component 50 is arranged on the other of the fixed base assembly 10 or the rotating knob cover 20, wherein the status detection component 30 is used to detect the axial position state of the rotating knob cover 20, and the gear detection component 40 is used to detect the trigger of the rotating knob cover 20 in the current axial position state. Gear, by setting a status detection component 30, when the status detection component 30 detects the trigger component 50 on the rotary knob cover 20, the rotary knob cover 20 is rotated, and the trigger component 50 is used to trigger the gear detection component 40 to complete the triggering of the gear corresponding function, and then the rotary knob cover 20 is reset and the rotary knob cover 20 is moved in a direction away from the fixed seat assembly 10. At this time, the status detection component 30 cannot detect the trigger component 50, and the rotary knob cover 20 is rotated to realize that the trigger component 50 triggers the status detection component 30 to trigger a new function. Compared with the traditional technical solution of only rotating to trigger the corresponding function, the present application can change the distance between the rotary knob cover 20 and the fixed seat assembly 10, and realize the rotary knob cover 20 triggering the gear detection component 40 at different positions by changing the trigger state of the trigger component 50 and the status detection component 30, thereby finally realizing the increase of the functions that can be realized by the knob mechanism and meeting the needs of multi-functions.
