Description

Technical Field

[0001] This utility model relates to the field of smart toilet technology, and in particular to a rotary knob with polarity. Background Technology

[0002] Currently, the function control of smart toilets mainly relies on physical buttons, touch screens, or mechanical knobs. Among them, mechanical knobs are widely used due to their intuitive operation, but they have significant drawbacks: 1. High mechanical complexity in function switching: Traditional multi-position knobs rely on physical limiting structures such as ratchet and latches to distinguish functions (e.g., male wash / female wash), which increases the number of parts, assembly costs, and failure rate. 2. Insufficient environmental adaptability: Physical contacts are prone to oxidation and failure in humid environments, and if the photoelectric sensor is fixed to the main board (not a follow-up structure), it cannot detect changes in the direction of rotation. Utility Model Content

[0003] In view of the shortcomings and defects of the existing technology, a polarized knob is provided. To achieve the desired function, the present invention provides the following technical solution.

[0004] A rotary knob includes a fixed base, a knob component, and a button. The knob component includes a fixed shaft and a rotating component. The fixed shaft is fixedly mounted on the fixed base, and the rotating component rotates around the fixed shaft. A light sensor is fixedly mounted on the rotating component. A rotating cavity is provided on the fixed shaft. The fixed base includes a first lamp post and a second lamp post disposed on both sides of the light sensor. Rotating the rotating component causes the light sensor to rotate within the rotating cavity. The direction of movement of the light sensor toward the first lamp post is a first direction X, and the direction of movement toward the second lamp post is a first direction Y. When the light sensor rotates toward the first direction X until it coincides with the first lamp post, the light sensor determines that it is for women's washing; when the light sensor rotates toward the second direction Y until it coincides with the second lamp post, the light sensor determines that it is for men's washing.

[0005] Compared with the existing technology, this utility model sets a light sensor receiver on the rotating part and symmetrically sets a first light column and a second light column on the fixed base. When the light sensor receiver rotates left and right to coincide with the first light column and the second light column respectively, pressing the button can realize the distinction between men's and women's washes. Moreover, the overall structure of the device is relatively simple and the operation during installation and use is also relatively convenient.

[0006] Furthermore, the rotating component has an extending mounting block inside the rotating cavity, the light sensor is fixedly mounted inside the mounting block, and limit surfaces are provided on both sides of the rotating cavity. When the mounting block rotates inside the rotating cavity, the rotating component rotates to its limit position when the side wall of the mounting block abuts against the limit surface.

[0007] Through the above improvements, a mounting block is provided in the rotating cavity of the rotating component, and the light sensor is set in the mounting block so that it can rotate with the rotating component; and limit surfaces are provided on both sides of the rotating cavity to limit the maximum rotation angle of the rotating component and prevent excessive rotation from damaging the components.

[0008] Furthermore, the fixing base includes a fixing plate and a sleeve. The sleeve includes a cover plate and a cylinder wall. The cover plate and the cylinder wall are integrally formed. The fixing plate is disposed inside the cylinder wall and cooperates with the cover plate. The cover plate is provided with a mating groove. The first lamp post and the second lamp post are snapped into the mating groove.

[0009] Through the above improvements, the mounting base includes a mounting plate and a sleeve. The sleeve includes an integrally formed cover plate and a sleeve wall, which can improve the overall strength of the device. The cover plate is provided with a mating groove, and the lamp post is fitted into the mating groove, which can better protect the lamp post and prevent damage to the lamp post during use. The mounting plate is provided with a limit block, and the cover plate is provided with a corresponding limit groove, which can improve the fit between the mounting plate and the sleeve and prevent the mounting plate and the sleeve from shifting during use, thus affecting the performance.

[0010] Furthermore, a button is provided on the fixed plate. The button includes an integrally formed pressing plate and a connecting rod. A connecting post is provided inside the fixed shaft. The connecting post is provided with a connecting groove. The connecting rod is inserted and fitted inside the connecting post. The lower end of the connecting rod abuts against the upper surface of the button.

[0011] With the above improvements, a button is set on the fixed plate. The button includes a pressing plate and a connecting rod. The pressure received on the pressing plate can be transmitted to the button through the connecting rod, making it easy to start. A connecting column is set inside the fixed shaft. The connecting column is provided with a connecting groove, which allows the connecting rod to make better contact with the button, so that it can be started more quickly and accurately when water is needed.

[0012] Furthermore, a torsion spring is provided on the outer side of the connecting column. The torsion spring includes a mating section and an abutting section. The mating section is sleeved on the connecting column, and the abutting section is mated on both sides of the mounting block. The rotating block rotates with the rotating component, causing the abutting section to rotate synchronously. After the rotation is completed, the abutting section causes the mounting block to reset.

[0013] With the above improvements, a torsion spring is provided on the outside of the connecting column. The torsion spring includes a mating section and an abutting section. The mating section is sleeved on the outer wall of the connecting column, and the abutting section is mated on both sides of the mounting block. When the mounting block rotates with the rotating block, the abutting section on one side is compressed and deformed. After the rotation is completed, the abutting section resets and drives the mounting block and the rotating part to reset, so that the rotating part can return to the initial state.

[0014] Furthermore, a fastener is integrally provided on the side of the pressing plate near the fixed base, and an abutment block is provided at the lower end of the fastener. A fastening groove is provided inside the fixed shaft, and the fastener is fitted into the fastening groove, with the abutment block abutting against the lower end face of the fixed shaft.

[0015] With the above improvements, a fastener is integrally provided at the lower end of the pressing plate, and an abutment block is provided at the lower end of the fastener. A fastening groove is provided on the fixed shaft, and the fastener is fitted into the fastening groove. The abutment block abuts against the lower end face of the fixed shaft. After the button is pressed and reset, the extreme position of the button can be limited, preventing the button from popping out of the device after use, thus reducing its service life.

[0020] like Figures 1 to 4 As shown, a polarized knob includes a fixed base 1, a knob component 2, and a button 3. The knob component 2 includes a fixed shaft 2.1 and a rotating component 2.2. The fixed shaft 2.1 is fixedly mounted on the fixed base 1, and the rotating component 2.2 rotates around the fixed shaft 2.1. A light sensor 2.21 is fixedly mounted on the rotating component 2.2. A rotating cavity 2.11 is provided on the fixed shaft 2.1. The fixed base 1 includes a first lamp post 1.1 and a second lamp post 1.2 symmetrically arranged on both sides of the light sensor 2.21. Component 2.2 drives the light sensor 2.21 to rotate within the rotating cavity 2.11. The direction in which the light sensor 2.21 moves toward the first lamp post 1.1 is the first direction X, and the direction in which it moves toward the second lamp post 1.2 is the first direction Y. When the light sensor 2.21 rotates toward the first direction X until it coincides with the first lamp post 1.1, the light sensor 2.21 determines that it is a female shower; when the light sensor 2.21 rotates toward the second direction Y until it coincides with the second lamp post 1.2, the light sensor 2.21 determines that it is a male shower.

[0021] The rotating component 2.2 has an extending mounting block 2.22 inside the rotating cavity 2.11. The light sensor 2.21 is fixedly mounted inside the mounting block 2.22, and the light sensor 2.21 is mounted inside the mounting block 2.22 so that it can rotate synchronously with the rotating component 2.2.

[0022] Limiting surfaces 2.12 are provided on both sides of the rotating cavity 2.11. The mounting block 2.22 rotates inside the rotating cavity 2.11. When the rotating component 2.2 rotates inside the rotating cavity 2.11, when the mounting block 2.22 rotates to abut against the limiting surface 2.12, it reaches the limit position of the rotation of the rotating component 2.2. The limiting surface 2.12 can limit the maximum rotation angle of the rotating component 2.2 and prevent excessive rotation from damaging the components.

[0023] The included angle between the two limiting surfaces 2.12 is 60 degrees. The initial position of the mounting block 2.22 of the rotating part 2.2 is set in the middle of the two limiting surfaces 2.12. That is, the maximum angle of rotation of the rotating part 2.2 in the clockwise direction from the initial state is 30 degrees, and the maximum angle of rotation in the counterclockwise direction is also 30 degrees.

[0024] The mounting base 1 includes a mounting plate 1.3 and a sleeve 1.4. The sleeve 1.4 includes a cover plate 1.41 and a cylindrical wall 1.42. The cover plate 1.41 and the cylindrical wall 1.42 are integrally formed, which can improve the overall strength of the device. The mounting plate 1.3 is set inside the cylindrical wall 1.42 and cooperates with the cover plate 1.41. The cover plate 1.41 has symmetrically arranged mating grooves 1.43 according to the initial position of the light sensor receiver 2.21. The first lamp post 1.1 and the second lamp post 1.2 are snapped into the mating grooves 1.43, which can better protect the lamp posts and prevent damage to the lamp posts during use. The mounting plate 1.3 is provided with a limiting block 1.31, and the cover plate 1.41 is provided with a corresponding limiting groove 1.44. The limiting block 1.31 is snapped into the limiting groove 1.44, which can improve the cooperation between the mounting plate 1.3 and the sleeve 1.4 and prevent the mounting plate 1.3 and the sleeve 1.4 from shifting during use and affecting the use effect.

[0025] A button 1.32 is provided on the fixed plate 1.3. The button 3 includes a pressing plate 3.1 and a connecting rod 3.2. The lower end of the connecting rod 3.2 abuts against the upper end face of the button 1.32. The connecting rod 3.2 can transmit the pressure received on the pressing plate 3.1 to the button 1.32 for easy start-up. A connecting post 2.13 is provided inside the fixed shaft 2.1. The connecting post 2.13 is provided with a connecting groove 2.14. The connecting rod 3.2 is inserted and fitted into the connecting post 2.13, which can better contact the connecting rod 3.2 with the button 1.32, and can start up quickly and accurately when water is needed.

[0026] A torsion spring 4 is provided on the outside of the connecting post 2.13. The torsion spring 4 includes a mating section 4.1 and an abutting section 4.2. The mating section 4.1 is sleeved on the outer wall of the connecting post 2.13, and the abutting section 4.2 is mated on both sides of the mounting block 2.22. The rotating block rotates with the rotating part 2.2, which drives the abutting section 4.2 to rotate synchronously. One side of the abutting section 4.2 is deformed under pressure. After rotation, when the deformed abutting section 4.2 returns to its original position, it will drive the mounting block 2.22 to reset.

[0027] The lower end of the pressing plate 3.1 is integrally provided with a fastener 3.3, and the lower end of the fastener 3.3 is provided with an abutment block 3.31. The fixed shaft 2.1 is provided with a fastening groove 2.15. The fastener 3.3 is fitted into the fastening groove 2.15, and the abutment block 3.31 abuts against the lower end face of the fixed shaft 2.1. After the button 3 is pressed and reset, it can limit the extreme position of the button 3, preventing the button 3 from popping out of the device after use, thus reducing its service life.

[0028] In use, the light sensor 2.21 and the rotating component 2.2 are set together by the mounting block 2.22. Therefore, the rotating component 2.2 and the light sensor 2.21 will rotate left and right together when rotating. When rotating left and right, the light source of the red lamp posts at the left and right ends of the fixed base 1 illuminates the light sensor 2.21 and inputs a signal to the main board. When the rotating component 2.2 rotates in the first direction X, that is, when the light sensor 2.21 coincides with the first lamp post 1.1, it is determined to be a female wash. When the rotating component 2.2 rotates in the second direction Y, that is, when the light sensor 2.21 coincides with the second lamp post 1.2, it is determined to be a male wash. After the rotation is completed, it is reset by the torsion spring 4.

All technical solutions falling within the scope of this utility model's concept are within its protection scope. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within its protection scope.
