Description

Technical Field

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

[0002] With increasingly stringent safety requirements for household and commercial appliances, the waterproof and moisture-proof performance of appliance operating interfaces has become one of the key technical challenges in product design. This is especially true for household appliances like water dispensers, which frequently come into direct contact with water; their waterproof performance not only affects the safe operation of the electrical system but also directly impacts the product's lifespan and the user experience.

[0003] Most water dispensers on the market currently use physical buttons or touchscreens as their operating interface. While these traditional designs are relatively simple in structure and intuitive to operate, they are susceptible to damage from moisture and water droplets during use. If the seal is inadequate, moisture can seep into the interior, causing button malfunctions, short circuits, and even safety hazards. To improve sealing performance, traditional water dispensers typically use methods such as adding sealing rubber parts to the knob and button structure, applying glue, or ultrasonic welding. While these methods improve the waterproof performance of the button area to some extent, they involve numerous assembly steps, require high processing precision, and have complex production processes, resulting in higher manufacturing costs.

[0049] 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.

[0050] use Figure 1 This document describes a waterproof rotary button. This waterproof rotary button can be used on water dispensers, specifically countertop water dispensers, floor-standing water dispensers, under-sink water purifiers, instant hot water dispensers, hot and cold water purifiers, and other water dispensers.

[0051] First, use Figures 2-5 The overall structure of this waterproof rotary button will be explained. Figure 2 This is one of the exploded views of the rotary seat 6 and the button 7 in this utility model. Figure 3 This is the second exploded view of the rotary seat 6 and the button 7 in this utility model. Figure 4 This is a schematic diagram of the light-shielding base 2 installed at the mounting port 101 in this utility model. Figure 5 This is a cross-sectional view of the rotary base 6 and the button 7 in this utility model.

[0052] The waterproof rotary button includes a mounting base 1, a light-shielding base 2, a control board 4, a rotating seat 6, a button 7, a waterproof button structure 8, and a waterproof rotating seat structure 9, wherein:

[0053] 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.

[0054] 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.

[0055] 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 11 that are configured to cooperate with each other.

[0056] 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.

[0057] The gap of button 7 is located inside the rotating seat 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 is installed to encoder 5.

[0058] Regarding the specific installation structure of the light guide 701, the light guide 701 is positioned within the assembly cavity 3. The bottom of the light guide 701 is hooked to the central cavity of the encoder 5. A tactile switch 11 is also provided in the central cavity of the encoder 5. The tactile switch 11 is located at the bottom of the light guide 701. Therefore, the button 7 and the rotating base 6 can be used relatively independently. That is, the button 7 can be pressed down independently, and the rotating base 6 can be rotated independently. There is no mutual interference between the rotating base 6 and the button 7.

[0059] The waterproof button structure 8 includes a drainage groove 801, a first waterproof protrusion 802, a second waterproof protrusion 803, and a third waterproof protrusion 804.

[0060] The specific installation structure between the drainage channel 801, the first waterproof protrusion 802, the second waterproof protrusion 803, and the third waterproof protrusion 804.

[0061] Specifically, the first waterproof protrusion 802 is a ring structure located on the top of the outer edge of the rotary seat 6, and the height of the first waterproof protrusion 802 is higher than the height of the button 7 when it is installed inside the rotary seat 6.

[0062] The second waterproof protrusion 803 has a ring structure and is spaced on one side of the first waterproof protrusion 802. The first waterproof protrusion 802 and the second waterproof protrusion 803 form a first spacer cavity 805.

[0063] The third waterproof protrusion 804 is a ring structure located at the bottom of the outer edge of the button 7, and the gap of the third waterproof protrusion 804 is located in the first spacer cavity 805, so that when the button 7 is installed in the rotating seat 6, there is no interference between the button 7 and the rotating seat 6, thus achieving the purpose of independent operation of the button 7.

[0064] The drainage channel 801 is opened on the bottom wall of the first partition cavity 805.

[0065] In one example, when water is poured onto the surface of button 7, the water flows through the gap between the first waterproof protrusion 802 and the third waterproof protrusion 804 to the first partition cavity 805. Then, due to the blocking effect of the second waterproof protrusion 803, the water flowing into the first partition cavity 805 is drained downwards along the drainage groove 801. That is, the water flows downwards due to gravity and will not overflow the second waterproof protrusion 803 to enter the circuit board, thus achieving the purpose of waterproofing button 7.

[0066] The rotating seat waterproof structure 9 includes a fourth waterproof protrusion 901, a fifth waterproof protrusion 902, and a sixth waterproof protrusion 903.

[0067] Regarding the specific installation structure between the fourth waterproof protrusion 901, the fifth waterproof protrusion 902, and the sixth waterproof protrusion 903.

[0068] Specifically, the fourth waterproof protrusion 901 is a ring structure, and the fourth waterproof protrusion 901 is located on the bottom of the outer edge of the rotating seat 6.

[0069] The fifth waterproof protrusion 902 has a ring structure and is spaced on one side of the fourth waterproof protrusion 901. The fourth waterproof protrusion 901 and the fifth waterproof protrusion 902 form a second spacer cavity 904.

[0070] The sixth waterproof protrusion 903 is installed on the top of the light-shielding base 2 and is located on the other side of the fifth waterproof protrusion 902. The drainage groove 801 is connected to the second partition cavity 904. A recessed groove space 10 is provided between the mounting base 1 and the sixth waterproof protrusion 903, and the bottom of the fifth waterproof protrusion 902 is located inside the groove space 10.

[0071] In one example, when water flows onto the mounting base 1, it is blocked by the sixth waterproof protrusion 903, causing it to flow out through the gap between the fourth waterproof protrusion 901 and the mounting base 1, thus preventing it from crossing the sixth waterproof protrusion 903 and entering the control panel 4. Furthermore, when water is poured onto the surface of the button 7, the drain channel 801 connects to the second partition cavity 904, allowing the water on the button 7 to drain into the second partition cavity 904, thus achieving the waterproofing purpose of the rotary base 6 and the button 7.

[0072] When water splashes from the side panel onto button 7, it enters through the gap between the fourth waterproof protrusion 901 and the mounting base 1, flowing towards the fifth waterproof protrusion 902 and the sixth waterproof protrusion 903. During this process, the fourth waterproof protrusion 901, the fifth waterproof protrusion 902, and the sixth waterproof protrusion 903 act as a barrier to the water flow, reducing the potential energy of the splash. When water flows into the recessed space 10, the water flow needs to traverse multiple 90-degree turns, thus ensuring that the splash cannot directly enter the interior of the control panel 4.

[0073] In this embodiment, the rotation operation control of the rotating base 6 is realized by connecting the extension 602 at the bottom of the rotating base 6 to the rotating component 501 of the encoder 5; the button 7 is spaced inside the rotating base 6 and connected to the tactile switch 11 inside the encoder 5 through the bottom light guide 701, realizing independent pressing control. The rotating base 6 and the button 7 do not interfere with each other and can be operated independently.

[0074] To achieve waterproof functionality for button 7, a first waterproof protrusion 802 is positioned on the top outer edge of the rotating base 6, a third waterproof protrusion 804 is positioned on the bottom outer edge of button 7, and a second waterproof protrusion 803 is located on one side of the first waterproof protrusion 802. The two together form a first spacer cavity 805. The second waterproof protrusion 803 prevents liquid from seeping into the encoder 5 or the control board 4, and water flowing onto button 7 can be drained downwards through the drain groove 801.

[0075] Meanwhile, a fourth waterproof protrusion 901 is disposed on the outer edge of the bottom of the rotating base 6. The fourth waterproof protrusion 901 and the fifth waterproof protrusion 902 form a second partition cavity 904, and a sixth waterproof protrusion 903 is installed on the top of the light-shielding base 2. The drainage groove 801 connects the first partition cavity 805 and the second partition cavity 904 to form a water guiding channel. The sixth waterproof protrusion 903 prevents liquid from seeping into the encoder 5 or the control board 4, and water splashed on the top or side of the button 7 is discharged through the drainage structure formed by the first partition cavity 805, the drainage groove 801, and the second partition cavity 904.

[0076] Compared with existing methods such as sealing rings, gluing, and welding, this solution forms a multi-layered waterproof barrier through multiple waterproof protrusions. It eliminates the need for additional sealing materials or complex assembly processes, achieving reliable waterproofing, structural stability, simplified production process, and reduced manufacturing costs. This significantly improves the safety and stability of drinking water equipment in humid environments and enhances the user experience.

[0077] In some embodiments, such as Figure 4 As shown. Figure 4This is a schematic diagram of the light-shielding base 2 installed to the mounting port 101 in this utility model. There are multiple drainage channels 801, which are arranged in a ring at intervals within the first partition cavity 805. In this embodiment, the multiple spaced drainage channels 801 facilitate the drainage of water accumulated inside the first partition cavity 805, improving the drainage efficiency.

[0078] In some embodiments, such as Figure 3 and Figure 6 As shown. Figure 3 This is the second exploded view of the rotary seat 6 and the button 7 in this utility model. Figure 6 This utility model Figure 5 Enlarged view at point A. Regarding the specific installation structure between the light-shielding base 2 and the mounting base 1: The bottom of the mounting opening 101 has a lower protrusion 12, which is annular. The top of the light-shielding base 2 has a mounting groove 13 that matches the lower protrusion 12, and the lower protrusion 12 is installed into the mounting groove 13. In this embodiment, to improve the stability of the installation between the light-shielding base 2 and the mounting base 1, the light-shielding base 2 is also screwed to the bottom wall of the mounting base 1.

[0079] In some embodiments, such as Figure 6 As shown. Figure 6 This utility model Figure 5 Enlarged view at point A. The lower protrusion 12 and the mounting groove 13 form a first gap 14, a second gap 15, and a third gap 16. In order for the light-shielding base 2 to be locked vertically to the bottom of the top cover mounting base 1, the first gap 14 is a clearance fit, the second gap 15 is an interference fit, and the third gap 16 is a clearance fit or an interference fit, thereby ensuring sealing performance.
