Description

Technical Field

[0001] This utility model relates to the field of smart toilet technology, and in particular to a control panel for a smart toilet seat. Background Technology

[0002] In modern home life, smart toilets are increasingly favored by consumers due to their various convenient functions, such as warm water washing, warm air drying, and heated seats. As a key operating component of smart toilets, the control panel plays a vital role in user command input and function control.

[0003] Traditional control panels for smart toilets typically consist of a top cover, a bottom cover, and a circuit board, with the circuit board housed within the mounting cavity formed by the top and bottom covers. Since smart toilets are usually installed in bathroom environments with high humidity and frequent splashing, water easily splashes onto the control panel surface, causing water accumulation. This water not only affects the user experience but also allows moisture to seep into the control panel through the gaps between the top and bottom covers. Once moisture enters the interior, it can easily cause electrical short circuits, corrosion, and other malfunctions on the circuit board, affecting the normal operation of the control panel and potentially even causing the entire smart toilet to malfunction. Therefore, developing a smart toilet control panel that effectively prevents surface water accumulation and is reliably waterproof internally is of great significance. Utility Model Content

[0036] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

Therefore, they should not be construed as limitations on this utility model.

[0038] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0039] like Figures 1 to 6 As shown, this embodiment discloses a control panel for a smart toilet seat. The control panel includes a control module 11 and a connection mechanism 12. The control module 11 includes a base 111, a circuit board 112, and a pressing top cover.

[0040] The pressing top cover is installed on the top of the base 111, and a mounting cavity is formed between the pressing top cover and the base 111. The circuit board 112 is installed in the mounting cavity.

[0041] The connecting mechanism 12 is installed on one side of the base 111. The base 111 is inclined downward relative to the connecting mechanism 12. The connecting mechanism 12 is used to connect to the external toilet core box. After the connecting mechanism 12 is horizontally installed on the side wall of the toilet core box, the base 111 is inclined downward along the horizontal plane, thereby making the entire control module 11 inclined downward along the horizontal plane. Preferably, the base 111 and the connecting mechanism 12 are integrally formed to ensure the stability of the overall structure.

[0042] A sealing and water-blocking structure is provided between the base 111 and the pressing top cover. The sealing and water-blocking structure is used to prevent external liquid media from penetrating into the mounting cavity. Specifically, the liquid media is water, aqueous solutions (such as disinfectant, toilet cleaner, saline solution, skin care toner, etc.).

[0043] The base 111 of this invention is designed to tilt downwards relative to the connecting mechanism 12. This allows the connecting mechanism 12 to be horizontally installed on the side wall of the toilet bowl housing, resulting in an inclined state for the entire control module 11. When water splashes or accumulates on the surface of the control module 11, the water will quickly slide off the inclined surface under gravity, effectively preventing water accumulation on the surface of the control module 11 and reducing the risk of water or aqueous solutions seeping into the control module 11. Simultaneously, a sealing and water-blocking structure is provided between the base 111 and the push-button top cover, forming a double waterproof barrier. This sealing and water-blocking structure prevents external liquid media from penetrating into the mounting cavity, preventing electrical components such as the circuit board 112 from getting damp or ingressed. This greatly improves the waterproof capability of the control panel, preventing electrical short circuits and corrosion of electrical components such as the circuit board, thereby ensuring the normal operation of the control panel.

[0044] Furthermore, the connecting mechanism 12 is used to connect to the external toilet core box. By tilting the base 111 downwards, the connecting mechanism 12 is horizontally installed on the side wall of the toilet core box, and the control module 11 automatically tilts, eliminating the need for additional complicated installation and adjustment steps and simplifying the installation process. At the same time, this design ensures that the connecting mechanism 12 is horizontally positioned when the control panel is installed in the toilet core box, allowing the control panel to better adapt to different models of toilet core boxes and improving the versatility and applicability of the control panel.

[0045] In one embodiment, the base 111 is tilted downwards at an angle of 5° to 35° relative to the connecting mechanism 12. That is, after the control panel is installed in the toilet seat housing, the entire control module 11 is tilted downwards at an angle of 5° to 35°. Within this range, the tilt angle ensures that surface water can quickly slide off while optimizing the user's operating experience. This allows the user's arm to be in a comfortable position when operating the control panel, avoiding both excessively small angles that affect waterproofing and excessively large angles that cause inconvenience. This improves the convenience and comfort of operating the control panel when using a smart toilet.

[0046] More preferably, the angle between the control module 11 and the horizontal plane is 5° to 20°.

[0047] In one embodiment, the press-top cover includes a button base 113 and a touch panel 114. The button base 113 is mounted on the top of the base 111, and the mounting cavity is formed between the button base 113 and the base 111. The touch panel 114 is mounted on the top of the button base 113.

[0048] The top of the base 111 is surrounded by a water-blocking strip 1112, which protrudes from the top surface of the base 111.

[0049] The button base 113 is provided with a limiting edge 1132 on its outer periphery. After the button base 113 is installed on the top of the base 111, the limiting edge 1132 and the water-blocking strip 1112 are engaged, and the limiting edge 1132 is located outside the water-blocking strip 1112. The water-blocking strip 1112 and the limiting edge 1132 cooperate to form the sealed water-blocking structure.

[0050] It is worth noting that the water-retaining strip 1112 surrounding the top of the base 111 protrudes from the top surface of the base 111 and cooperates with the limiting edge 1132 of the button base 113 to form a double waterproof barrier. The limiting edge 1132 covers the top surface of the base 111 and is located outside the water-retaining strip 1112. It can prevent splashing water from directly contacting the gap between the base 111 and the button base 113. Even if water crosses the limiting edge 1132, the water-retaining strip 1112 can further prevent water from entering the mounting cavity, preventing electrical components such as the circuit board 112 from getting damp or water ingress. This greatly improves the waterproof capability of the control panel, avoids electrical short circuits and corrosion of electrical components such as the circuit board, and thus ensures the normal operation of the control panel.

[0051] In one embodiment, the bottom wall of the button base 113 is surrounded by a water-retaining wall 1135. The height of the water-retaining wall 1135 is greater than the height of the limiting edge 1132. A circuit board mounting space 11351 is formed between the inner walls of the water-retaining wall 1135. The size of the circuit board mounting space 11351 matches the size of the circuit board 112, and the circuit board 112 is installed in the circuit board mounting space 11351. Due to the water-retaining wall 1135, even if moisture enters the mounting cavity under special circumstances, it can prevent moisture from directly contacting the circuit board 112, which can further protect the circuit board 112, reduce the risk of short circuits and damage to the circuit board, improve the waterproof reliability of the control panel, and extend its service life. Furthermore, since the size of the circuit board mounting space 11351 matches the size of the circuit board 112, the water-retaining wall can act as a limiter when installing the circuit board, so that the circuit board 112 can be accurately installed in the predetermined position, preventing the circuit board 112 from shifting during installation, and ensuring that the conductive springs on the circuit board 112 are correctly connected to the buttons 1134 on the button base.

[0052] In one embodiment, the side of the button base 113 away from the connecting mechanism 12 is arc-shaped or has a smooth curved surface, extending to the bottom end of the base 111. The arc-shaped or smooth curved surface design, without sharp edges, allows water splashed onto the surface of the pressing top cover to flow more smoothly along the curved surface to the bottom end of the base 111 under gravity, and from the bottom end of the base 111 to the outside of the control panel. This effectively prevents water from seeping into the mounting cavity during the flow process. Together with the water-blocking strip 1112, the limiting edge 1132, and other structures, it forms a more complete waterproof system, improving the waterproof performance of the control panel.

[0053] In one embodiment, the base 111 has a plurality of support plates 1111 inside for supporting the circuit board 112. The support plates 1111 are spaced apart inside the base 111, with one end connected to the inner wall of the base 111 and the other end abutting against the bottom surface of the circuit board 112. The cooperation of the bottom wall of the button base 113, the water-retaining wall 1135, and the support plates 1111 restricts the installation position of the circuit board 112, preventing it from moving. Furthermore, by supporting the circuit board 112 with the support plates 1111 inside the base 111, when a button on the button base 112 is pressed, the circuit board 112 is effectively prevented from moving downwards, ensuring the accuracy and stability of button operation and preventing button malfunction or incorrect operation due to circuit board movement, thereby improving the user experience.

[0054] In one embodiment, the bottom wall of the button base 113 is provided with a plurality of limiting blocks 1133, and a water-blocking strip installation space is formed between the limiting perimeter 1132 and the limiting blocks 1133.

[0055] The inner wall of the limiting perimeter 1132 is provided with a plurality of snap-fit ​​blocks 11321, and the outer side of the water-blocking strip 1112 is provided with a plurality of snap-fit ​​grooves 11121 that match the snap-fit ​​blocks 11321; the shape and size of the snap-fit ​​blocks 11321 match the snap-fit ​​grooves 11121, so that the snap-fit ​​blocks 11321 can be inserted into the snap-fit ​​grooves 11121, and the connection and fixation between the base 111 and the button base 113 are realized through the interference fit or other fastening methods between the two.

[0056] The water-blocking strip 1112 is installed in the water-blocking strip installation space, and the snap-fit ​​block 11321 is located in the snap-fit ​​groove 11121.

[0057] In one embodiment, the control module 11 further includes a first fixing member (not shown) and a second fixing member 117. The circuit board 112 is mounted below the button holder 113 via the second fixing member 117, and the button holder 113 is fixedly mounted to the top of the base 111 via the first fixing member. The first and second fixing members further secure the button holder 113 and the circuit board 112, making the connection between the components more stable and ensuring that the components of the control panel will not shift during use, thus ensuring the reliability and stability of the control panel operation.

[0058] In one embodiment, the first fastener and the second fastener 117 may be screws or bolts.

[0059] In one embodiment, the top of the button base 113 is provided with a touch panel mounting groove 1131 that is adapted to the touch panel 114, and the touch panel 114 is bonded to the touch panel mounting groove 1131. Bonding achieves a tight connection between the top surface of the touch panel 114 and the button base 113, preventing moisture from entering the control module 11 from the connection point between the touch panel 114 and the button base 113.

[0060] Preferably, the touch panel 114 is an ABS panel, that is, the touch panel 114 is a panel made of acrylonitrile-butadiene-styrene copolymer, which gives the touch panel 114 better impact strength, good dimensional stability, low water absorption, corrosion resistance and excellent chemical and electrical insulation properties, which not only provides better protection but also extends the service life of the control panel.

[0061] In one embodiment, the circuit board 112 is provided with a plurality of conductive springs 1121, and each conductive spring 1121 is provided with a corresponding solder pad (not shown in the figure) below it.

[0062] The button base 113 includes a button base body (not shown in the figure) and a plurality of buttons 1134, wherein the plurality of buttons 1134 are movably mounted on the button base body;

[0063] The limiting perimeter 1132 is disposed on the outer periphery of the button base body, the water-blocking wall 1135 and a plurality of the limiting blocks 1133 are all installed on the bottom wall of the button base body, and the plurality of the limiting blocks 1133 are located outside the water-blocking wall 1135.

[0064] The touch panel 114 is provided with a plurality of touch parts 1141, and the positions of the conductive spring 1121, the button 1134, and the touch parts 1141 correspond one-to-one. This ensures that when the user presses the touch part 1141, the button force transmitted through the button 1134 accurately triggers the conductive spring 1121, achieving stable transmission of electrical signals, ensuring the accuracy and reliability of the control panel operation, and enabling the smart toilet to correctly respond to various operation commands.

[0065] In one embodiment, the conductive spring 1121 is a metal dome switch. When the contact part 1141 is not pressed, there is no contact between the conductive spring 1121 and the pad. When a contact part 1141 is pressed, the button force is transmitted through the button 1134, causing the corresponding metal dome switch to deform, recessing to contact the circuit, forming a loop to trigger the corresponding function. When the button is released, the metal dome switch returns to its original shape. The metal dome switch provides a light and smooth touch, requires less pressing force, and has low noise during operation.

[0066] In one embodiment, the button 1134 includes a pressing part 11341 and a trigger part 11342. The pressing part 11341 is movably connected to the button base body. The pressing part 11341 is bonded to the touch part 1141. The trigger part 11342 is installed on the side of the pressing part 11341 near the circuit board 112, and the position of the trigger part 11342 corresponds to the position of the conductive spring 1121. Specifically, a movable hole for the button 1134 to move up and down can be provided in the main body of the button base. The diameter of the movable hole is larger than the diameter of the pressing part 11341. One side of the pressing part 11341 is connected to the main body of the button base through an elastic connecting part, and the pressing part 11341 is located in the movable hole, so that the pressing part 11341 is movably installed on the main body of the button base. When the user presses the touch part 1141, the pressing part 11341 can move downward, and when the touch part 1141 is released, the pressing part 11341 can return to its original position.

[0067] In one embodiment, the distance between the trigger part 11342 and the conductive spring 1121 is 0.02 to 0.8 mm; preferably, the distance between the trigger part 11342 and the conductive spring 1121 is 0.05 to 0.3 mm.

[0068] The top surface of the pressing part 11341 protrudes 0.2mm to 0.7mm from the surface of the button base body, and the top surface of the touching part 1141 protrudes 0.2mm to 0.7mm from the surface of the touch panel 114. By defining the dimensions of the pressing part 11341 and the touching part 1141, as well as the distance between the trigger part 11342 and the conductive spring 1121, the pressing part and the touching part have appropriate protrusion heights, and the trigger part 11342 and the conductive spring 1121 maintain an appropriate distance. This ensures comfortable button operation, and that pressing the button quickly and accurately triggers the conductive spring, forming an electrical signal path, thereby triggering the corresponding function and improving the sensitivity and reliability of the control panel operation.

[0069] Preferably, the side wall of the toilet core box 2 is provided with a mounting hole that matches the connecting mechanism 12. The connecting mechanism 12 passes through the mounting hole and connects to the toilet core box 2, thereby allowing the control panel to be detachably installed on one side of the toilet core box 2.

[0070] In one embodiment, the connecting mechanism 12 includes a first connecting part 121 and a second connecting part 122. The first connecting part 121 is connected to the control module 11 to facilitate electrical connection between the control circuit and control panel inside the toilet core box. The first connecting part 121 is located above the second connecting part 122 and protrudes from the second connecting part 122. The size and shape of the first connecting part 121 are respectively matched with the size and shape of the mounting hole.

[0071] The first connecting part 121 is installed in the mounting hole 21, and is detachably connected to the inner wall of the toilet core box via fasteners (such as bolts), thus restricting the vertical position of the control panel. The second connecting part 122 is detachably connected to the side wall of the toilet core box via fasteners (such as bolts), thus restricting the horizontal position of the control panel. This achieves a secure connection between the control panel and the toilet core box, allowing the entire control panel to be stably installed on one side of the toilet core box. During use, this effectively prevents the control panel from shaking or becoming loose, ensuring a smooth operating experience and avoiding interference with wiring due to loose connections, thereby ensuring the normal operation of the smart toilet.

[0072] In one embodiment, the bottom of the first connecting part 121 near the toilet core box has a notch 1211; this facilitates the connection of a fastener (such as a bolt) through the first connecting part 121 to the inner wall of the toilet core box, thereby improving installation efficiency.

[0073] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without any inventive effort, and these embodiments will all fall within the scope of protection of this utility model.
