Description

Technical Field

[0001] This utility model belongs to the field of knob and button technology, and particularly relates to a knob and button and its drinking water device. Background Technology

[0002] In modern electronic and mechanical equipment, knobs and buttons are commonly used human-machine interface components, widely applied in various devices such as water dispensers. Knobs are typically used to adjust parameters (such as water temperature or flow rate), while buttons are used to start or stop corresponding functions. In practical use, these control components not only require a compact structure but also good tactile feedback and high reliability.

[0003] In traditional designs, knobs and buttons are often coaxially mounted, but this structure is prone to problems in practical applications. Firstly, when the knob's axis is not perfectly aligned with the button's axis during rotation, it can cause jamming between the knob and button, affecting the smoothness of operation and potentially leading to malfunction. Secondly, due to limitations in mechanical manufacturing and assembly precision, buttons often have significant play, causing them to wobble or wobble during operation, which not only affects the user experience but also reduces the product's lifespan.

It is used to form an interference fit with the inner wall of the rotating base and the outer wall of the button, respectively, so that the button can move axially while the rotating base rotates and remain axially concentric with the rotating base.

[0011] In one possible implementation, the limiting ring body is provided with alternating protrusions and recesses in its circumference, the protrusions constituting the external convex structure and the bottom wall of the recesses constituting the internal convex structure.

[0012] In one possible implementation, the limiting ring is a regular polygonal ring structure, the outer corners of the limiting ring form the convex structure, the recessed structure is disposed between the outer corners of the limiting ring, and the bottom wall of the recessed structure forms the convex structure.

[0014] In one possible implementation, a support platform for mounting the limiting ring is provided on the side wall of the opening, and the bottom wall of the limiting ring is located on the top wall of the support platform.

[0015] In one possible implementation, the limiting ring is made of an elastic material with self-lubricating and wear-resistant properties.

[0016] In one possible implementation, the bottom of the rotary base is fitted with a downwardly protruding extension that passes through the assembly cavity and is mounted to the rotary component of the encoder.

[0019] Secondly, this application also provides a drinking water device, which includes a mounting base and a knob and button as described in the first aspect above, wherein the knob and button are mounted on the mounting base.

[0020] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0021] In this invention, a reasonable movement gap is reserved between the rotating base and the button, so that the rotating base can rotate smoothly without affecting the axial pressing of the button. The limiting ring is set between the rotating base and the button, and its outward convex structure forms an interference fit with the inner wall of the rotating base and the inner convex structure forms an interference fit with the outer wall of the button, so that the axial concentricity of the two is achieved during the rotation of the rotating base and the axial movement of the button, avoiding the button from shaking or deviating, and improving the operational stability and user experience.

[0038] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0039] use Figure 1 This section describes a type of knob or button. Figure 1 This is a schematic diagram of the rotary button installed on the mounting base 1 in this utility model. The rotary button can be used on drinking water equipment, specifically tabletop water dispensers, floor-standing water dispensers, under-sink water purifiers, instant hot water dispensers, hot and cold water purifiers, and other drinking water equipment.

[0040] First, use Figure 2 The overall structure of the knob / button will be explained. Figure 2 This is an exploded view of the knob and button mounted on the mounting base 1 in this utility model.

[0041] like Figures 3-5 , Figure 3 This is one of the exploded views of the knob and button in this utility model. Figure 4 This is the second exploded view of the knob and button in this utility model. Figure 5 This is a cross-sectional view of the knob / button in this utility model. The knob / button can be mounted on the mounting base 1 for use. Regarding the specific structure of the knob / button, it may include a light-shielding base 2, a control plate 4, a rotating base 6, a button 7, and a limiting ring 8, wherein:

[0042] The mounting base 1 has a mounting opening 101 on its surface. The mounting base 1 has the function of supporting and bearing load, so as to install other components in the waterproof rotary button.

[0043] The light-shielding base 2 is located at the bottom of the mounting base 1, and the light-shielding base 2 has an assembly cavity 3 in the middle and is installed into the mounting port 101 at the top.

[0044] The control board 4 can be a PCB board, and the light-shielding base 2 has a bottom opening structure. The bottom opening connects to the assembly cavity 3. The control board 4 can be installed on the bottom of the light-shielding base 2. An encoder 5 is installed on the control board 4. The encoder 5 includes a rotating part 501 and a tactile switch 502 that are configured to cooperate with each other.

[0045] The rotary seat 6 has an opening 601 in the middle, and the bottom of the rotary seat 6 has an assembly cavity 3 and is installed on the encoder 5. Specifically, the bottom of the rotary seat 6 has a downward protruding extension 602, which passes through the assembly cavity 3 and is installed on the rotating part 501 of the encoder 5. Therefore, the rotary seat 6 can be rotated and adjusted.

[0046] The gap of button 7 is located inside the rotating base 6, and the bottom of button 7 is provided with an opening 601 to connect to encoder 5. Specifically, the bottom of button 7 is connected to a light guide 701, which passes through the assembly cavity 3 and hooks into the middle cavity of encoder 5. A tactile switch 502 is also provided in the middle cavity of encoder 5, and the tactile switch 502 is located at the bottom of light guide 701.

[0047] The limiting ring 8 can be installed between the rotating base 6 and the button 7. The outer periphery of the limiting ring 8 is provided with a plurality of outward protruding structures 801 for contacting the rotating base 6, and the inner side of the limiting ring 8 is provided with a plurality of inward protruding structures 802 for contacting the button 7. The outward protruding structures 801 are used to form an interference fit with the inner wall of the rotating base 6, and the inward protruding structures 802 are used to form an interference fit with the outer wall of the button 7.

[0048] In this embodiment, the rotary seat 6 and the button 7 have sufficient clearance for movement, and the limiting ring 8 is made of an elastic material with self-lubricating and wear-resistant properties. When the knob / button is in use, the rotary seat 6 rotates while the button 7 remains stationary. Due to the clearance between the rotary seat 6 and the button 7, the rotary seat 6 can rotate smoothly. Furthermore, through the coordinated arrangement of multiple external convex structures 801 and multiple internal convex structures 802, the limiting ring 8 located between the rotary seat 6 and the button 7 allows the button 7 to move axially while the rotary seat 6 rotates, maintaining axial concentricity with the rotary seat 6. This prevents the button 7 from shaking or wobbling during operation, improving the user experience and extending the product's lifespan.

[0049] In some embodiments, such as Figures 3-5 As shown. Figure 3 This is one of the exploded views of the knob and button in this utility model. Figure 4 This is the second exploded view of the knob and button in this utility model. Figure 5 This is a cross-sectional view of the knob button in this utility model. An annular lower edge 702 is connected to the bottom surface of the button 7, and a light guide 701 is connected to the bottom end of the annular lower edge 702.

[0050] The lower annular edge 702 is located inside the opening 601. The limiting ring 8 is installed between the rotating seat 6 and the lower annular edge 702. The inner convex structure 802 abuts against the outer peripheral surface of the lower annular edge 702, while the outer convex structure 801 abuts against the inner wall of the rotating seat 6. That is, the outer convex structure 801 of the limiting ring 8 and the inner wall of the rotating seat 6 form an interference fit, and the inner convex structure 802 and the outer peripheral surface of the lower annular edge 702 form an interference fit.

[0051] In order to install the limiting ring 8 into the interior of the rotating seat 6, a support platform 9 for installing the limiting ring 8 is provided on the side wall of the opening 601, and the bottom wall of the limiting ring 8 is provided on the top wall of the support platform 9.

[0052] In this embodiment, when the user presses the button 7 axially, the limiting ring 8 restricts the radial displacement of the lower edge 702 of the ring through multiple inner protrusions 802. At the same time, multiple outer protrusions 801 cooperate with the inner wall of the rotating seat 6 to maintain the concentricity of the rotating seat 6 and the button 7 in the axial direction. The rotating seat 6 can rotate freely relative to the button 7, while the button 7 can move axially independently. The two actions do not interfere with each other.

[0053] In some embodiments, such as Figure 6 As shown. Figure 6 This is a schematic diagram of the rotating seat 6 and the limiting ring 8 in this utility model. Regarding the specific structure of the limiting ring 8, the limiting ring 8 has alternating protruding and recessed structures along its circumference. The protruding structures form an outwardly convex structure 801, and the bottom wall of the recessed structures forms an inwardly convex structure 802. Specifically, the limiting ring 8 can be a regular polygonal ring structure, such as a regular quadrilateral, a regular pentagon, a regular hexagon, or other regular polygons. Figure 6 The limiting ring 8 shown is only a schematic diagram of a regular hexagonal deformation. The limiting ring 8 described below is a regular hexagonal deformation. The outer corner of the limiting ring 8 forms an outward convex structure 801, and the concave structure is provided between the outer corners of the limiting ring 8. The bottom wall of the concave structure forms an inward convex structure 802.

[0054] In this embodiment, the six protruding structures 801 on the periphery of the limiting ring 8 make line contact with the inner wall of the rotating seat 6, and point contact is smoother than surface contact; the protruding structures 802 on the inner side of the limiting ring 8 make line contact with the outer wall of the lower edge of the ring 702, and point contact is smoother than surface contact.

[0055] Because existing knob and button designs have assembly gaps, instability in production or part misalignment can lead to eccentricity, causing the gap on one side to be too small, resulting in jamming during knob movement. In one example, during assembly of the limiting ring 8, the outward convex structure 801 is interference-fitted with the inner wall of the rotating seat 6, and the inward convex structure 802 is interference-fitted with the outer wall of the lower annular edge 702, thus fixing the rotating seat 6 and the button 7 on the same axis by the limiting ring 8. When the rotating seat 6 rotates, the inner wall of the rotating seat 6 rubs against the outward convex structure 801 of the limiting ring 8, and the inward convex structure 802 of the limiting ring 8 rubs against the outer wall of the lower annular edge 702. The limiting ring 8 is made of a self-lubricating wear-resistant material, so that when the rotating seat 6 rotates, the limiting ring 8 interferes with the rotation of the button 7, ensuring that the rotating seat 6 and the button 7 can rotate smoothly while remaining coaxial.

[0056] The limiting ring 8 has a notch 803 on one side. The interference fit allows the limiting ring 8 to effectively constrain the moving parts and avoid motion interference caused by rigid fit. The flexible fit ensures the concentricity of the rotating seat 6 and the button 7 when they are in operation, and the uniformity of the movement gap is guaranteed, eliminating the wobble caused by the assembly gap.

[0057] By providing protrusions on both the inner and outer sides of the limiting ring 8, the limiting ring 8 is in close contact with and fixed to the button 7 and the rotating seat 6, respectively. When the button 7 is subjected to a lateral force and tends to wobble, the button 7 transmits the force to the limiting ring 8 through its contact with the inner protruding structure 802 on the inner side of the limiting ring 8. Subsequently, the limiting ring 8 continues to transmit the force to the rotating seat 6 through its outer protruding structure 801. This force transmission helps to counteract the tendency to wobble.

[0058] Furthermore, the flexible structure of the limiting ring 8 allows it to generate a suitable clamping force after interference fit. This clamping force not only enhances the overall stability of the structure but also generates an equal reaction force when the button attempts to wobble, effectively maintaining the vertical state of the button 7 and significantly reducing the possibility of wobble. This design not only ensures the smoothness and accuracy of the operation of the rotating base 6 and the button 7 but also significantly improves the mechanical stability and durability of the entire device.

[0059] In this embodiment, a flexible limiting ring 8 is provided between the rotating base 6 and the button 7. This limiting ring 8 is made of a material with a certain degree of elasticity, ensuring that even slight displacement caused by axial offset during the rotation of the rotating base 6 will not lead to jamming or operational difficulties between the rotating base 6 and the button 7, thereby significantly improving the stability and smoothness of operation. The outwardly protruding structure 801 on the limiting ring 8 mates with the inner wall of the rotating base 6, and the inwardly protruding structure 802 mates with the outer wall of the button 7, reducing the wobbling problem caused by assembly tolerances, effectively limiting the radial movement of the button 7, improving the tactile feel and feedback accuracy of the button 7; it also avoids structural fatigue or damage caused by frequent shaking, improving the overall durability of the equipment.

[0060] In addition, the limiting ring 8 has good adaptability and elasticity, and can still maintain good cooperation between the rotating base 6 and the button 7 under long-term use or extreme working conditions, reducing maintenance frequency and replacement risk, and improving the reliability and long-term stability of the whole machine.
