Description

Technical Field

[0001] This utility model relates to the field of smart toilet technology, and in particular to a stepless knob. 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 wheels 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 rotation direction. Utility Model Content

[0003] In view of the shortcomings and defects of the existing technology, a stepless knob is provided to achieve the purpose of separating men's and women's washing. The present invention provides the following technical solution.

[0004] A stepless knob includes a fixed base, a knob component, and a button. The knob component includes a fixed shaft and a rotating ring. The fixed shaft is fixedly mounted on the fixed base, and the knob rotates around the fixed shaft. The fixed base has a lamp post and a mating groove arranged symmetrically around its center position. The mating groove includes a first end and a second end. The lamp post is mated and installed in the first end. A light sensor is fixedly mounted on the rotating ring. The rotation of the rotating ring drives the light sensor to rotate. When the light sensor rotates from the first end to the second end and rotates until it coincides with the lamp post, the light sensor determines that it is for men's washing; when the light sensor rotates from the first end to the second end, the light sensor determines that it is for women's washing.

[0005] Compared with existing technologies, this utility model determines the alignment of the light sensor receiver with the lamp post by rotating the rotating component in different directions. When the rotating ring rotates towards the side closer to the lamp post, the intensity of the light source increases as it rotates, which is determined to be a right rotation, enabling the male wash function. When the rotating ring rotates away from the lamp post, the light source intensity reaches its maximum instantaneously, which is determined to be a left rotation, enabling the female wash function. This allows for the differentiation between male and female wash functions in the smart toilet, and the structure is convenient, practical, and easy to operate.

[0006] Furthermore, the fixing base includes a fixing plate and a sleeve. The sleeve includes an integrally formed cover plate and a cylinder wall. The fixing plate is fitted inside the cylinder wall and abuts against the side of the cover plate near the cylinder wall. The lamp post is fixedly installed on the fixing plate, and the mating groove is provided on the cover plate.

[0007] Through the above improvements, the fixing base includes a fixing plate and a sleeve. The sleeve includes an integrally set 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 mated in the mating groove, which can better protect the lamp post and prevent damage to the lamp post during use.

[0008] Furthermore, the fixing plate is provided with a mating hole, and a fixing post is inserted into the mating hole. One end of the fixing post is provided with a limit block, which abuts against the fixing plate. The fixing shaft is provided with a positioning groove, and the fixing post is inserted into the positioning groove.

[0009] Through the above improvements, the fixing plate is provided with mating holes, and a fixing post is inserted into the mating holes. One end of the fixing post is provided with a limit block, so that the fixing post can be better installed on the fixing plate and prevent it from falling off during use. The fixing shaft is provided with a positioning groove, and the fixing post is inserted into the positioning groove to limit the fixing shaft, so that the installation effect of the fixing shaft is better and prevents it from shaking during use, which would affect the final result.

[0010] Furthermore, a button is provided on the fixing plate. The button includes a pressing plate and a connecting rod. One end of the connecting rod is integrally formed with the pressing plate, and the other end abuts against the upper end of the button.

[0011] With the above improvements, a button is provided on the fixed plate. The button includes a pressing plate and a connecting rod. The connecting rod can transmit the pressure received on the pressing plate to the button, making it easy to start.

[0012] Furthermore, 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. An abutment platform is provided on the inner side of the fixed shaft, and the abutment block abuts against the lower end of the abutment platform.

[0013] 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. An abutment platform is provided on the inner side of the fixed shaft. The abutment platform abuts against the abutment block, which can limit the extreme position of the button and prevent the button from disengaging from the device during use, thus reducing its service life.

[0014] Furthermore, the inner wall of the rotating ring extends radially to form a fixed platform, and the light sensor is fixedly mounted on the fixed platform. The rotation of the rotating ring drives the light sensor to rotate synchronously.

[0015] Through the above improvements, a fixed platform is set on the inner wall of the rotating ring. The fixed platform is used to assemble the light sensor receiver, so that the light sensor receiver can rotate synchronously, which improves the ease of use.

[0016] Furthermore, a toothed groove is provided on the outer wall of the fixed shaft, and an abutting post is provided on the inner wall of the rotating ring. The tip of the abutting post abuts against the toothed groove. A groove is provided on the side of the abutting post away from the fixed shaft. An elastic element is connected between the rotating ring and the abutting post. One end of the elastic element abuts against the inner wall of the rotating ring, and the other end abuts against the groove.

[0017] Through the above improvements, a toothed groove is provided on the outer wall of the fixed shaft, and an abutment post is provided on the inner wall of the rotating ring. This ensures that the abutment block remains within the toothed groove when the rotating ring rotates, improving the abrasive feel during rotation. Furthermore, the rotating ring is better fixed after rotation is completed. An elastic element is provided between the abutment post and the rotating ring to better assist the abutment post in abutting the fixed shaft. Attached Figure Description

The lamp post 1.1 is fitted into the first end 1.41, and the rotating ring 2.2... A light sensor 2.21 is fixedly installed. The rotating ring 2.2 rotates, causing the light sensor 2.21 to rotate. The light sensor 2.21 rotates from the first end 1.41 to the second end 1.42. When it rotates to coincide with the lamp post 1.1, the light sensor 2.21 determines that it is a male shower. When the light sensor 2.21 rotates from the first end 1.41 to the second end 1.42 and coincides with the lamp post 1.1, the light sensor 2.21 determines that it is a female shower.

[0023] When the rotating ring 2.2 rotates towards the side closer to the lamp post 1.1, the intensity of the light source increases as it rotates. When the red LED and the yellow light sensor 2.21 overlap, the light intensity is at its maximum, which is determined to be a right rotation, thus enabling the men's washing function. When the rotating ring 2.2 rotates away from the lamp post 1.1, the light source intensity reaches its maximum instantaneously, which is determined to be a left rotation, thus enabling the women's washing function.

[0024] The mounting base 1 includes a mounting plate 1.2 and a sleeve 1.3. The sleeve 1.3 includes an integrally formed cover plate 1.31 and a cylindrical wall 1.32, which can improve the overall strength of the device.
