Description

Technical Field

[0001] This utility model relates to toilets, and more particularly to a foam shield leak-proof structure and a smart toilet seat using the same. Background Technology

[0002] In existing smart toilet products, the foam shield prevents waste from splashing after falling into the liquid seal and isolates odors, making it more hygienic and improving the user experience. However, the foaming device and foam filling port of existing smart toilets are located inside the lid. If there is residual foam liquid in the foaming device and foam filling port during maintenance or disassembly, the foam liquid can flow into the mechanism and lid due to the lid tilting or flipping, causing corrosion or damage to the electronic components of the mechanism and lid. Some solutions involve designing a foam liquid leakage port to drain the foam liquid before maintenance or disassembly, but this method not only wastes foam liquid but also increases maintenance time.

[0031] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0032] This utility model relates to a foam shield leak-proof structure, including an inlet pipe 100, a pressure member 200, and a ball 400. It also relates to a smart toilet seat and a toilet bowl, such as... Figure 1 and Figure 5 As shown, the foam shield leak-proof structure 001 is applied to smart toilet seats or toilets. Smart toilet seats can also be applied to toilets.

[0033] like Figure 1 , Figure 3 and Figure 4 As shown, in this embodiment, the inlet pipe 100 is a long straight pipe, but it can also be a bent pipe, an oblique pipe, or other shapes. The inlet pipe 100 mainly serves as a pre-installed pipe for the foam shield device, guiding the foaming agent into the main body of the foam shield device. A pressure member 200 is installed in the inlet pipe 100, defining a liquid-passing space 300 within the inlet pipe 100 and at its lower side. The liquid-passing space 300 is connected to the lower part of the inlet pipe 100. A through hole 210 is provided on the pressure member 200, connecting the upper space of the pressure member 200 to the liquid-passing space 300. A sphere 400 is installed in the liquid-passing space 300. The sphere 400 can be a solid stainless steel sphere or other spherical components. The sphere 400 can roll up and down within the liquid-passing space 300. The bottom of the liquid-passing space 300 can be configured as a mesh structure, a perforated structure, etc. The maximum outer diameter of the sphere 400 is larger than the diameter of the through hole 210, and the maximum outer diameter of the sphere 400 is smaller than the inner diameter of the liquid passage space 300. The position of the sphere 400 within the liquid passage space 300 changes according to the placement of the inlet pipe 100. When the sphere 400 moves, it has both an open position and a closed position relative to the through hole 210. Figure 1 As shown, the open position is when the ball 400 leaves the through hole 210. At this position, the foaming agent can be introduced from the upper end of the inlet pipe 100 into the inlet pipe 100, then flow through the through hole 210 and the liquid passage space 300 before flowing to the lower end of the inlet pipe 100, and finally guided into the foam shield device for use. When the foam shield device tilts or falls over, the position of the inlet pipe 100 changes, and the foaming agent remaining in the foam shield device will flow back towards the inlet pipe 100. As the position of the inlet pipe 100 changes, the ball 400 moves to the blocking position in the liquid passage space 300. Figure 2 As shown, the sealing position is achieved when the ball 400 moves to seal the through hole 210. At this time, the foaming agent flowing back into the inlet pipe 100 cannot flow out of the inlet pipe 100 because the through hole 210 is blocked, thus achieving a leak-proof function. When disassembling or repairing the smart toilet seat or other appliances, the foam shield leak-proof structure can prevent leaks, eliminating the need to drain the foaming agent before disassembly, improving disassembly efficiency, and preventing foam liquid from flowing onto other electronic components of the smart toilet seat due to tilting or tipping, thus preventing damage and corrosion to the electronic components and reducing foam liquid waste.

[0034] In this embodiment, as Figure 1As shown, the inlet pipe 100 is in its normal working position when placed vertically. At this time, the ball 400 moves and rolls under its own weight to and stops at the bottom of the liquid passage space 300. The liquid passage space 300 remains connected to the inlet pipe 100. The ball 400 moves away and is located below the through hole 210. The position of the ball 400 relative to the through hole 210 is the open position. Figure 2 As shown, when the inlet pipe 100 is tilted from its normal operating position, i.e., when the inlet pipe 100 is tilted or upside down, the ball 400 will roll towards the through hole 210 within the liquid passage space 300. When the inlet pipe 100 is tilted to a position where the foaming agent inside can flow out through the through hole 210, the ball 400 has rolled to block the through hole 210. Simultaneously, under the effect of the foaming agent accumulating towards the through hole 210, the foaming agent can compress the ball 400 towards the through hole 210, resulting in a better sealing effect of the ball 400 on the through hole 210. This position is the sealing position of the ball 400 relative to the through hole 210.

[0035] It is understood that the axial orientation of the through hole 210 can be vertical or inclined, as long as the ball 400 can block the through hole 210 when the inlet pipe 100 deviates from its normal operating position. In this embodiment, when the axial orientation of the through hole 210 is vertical, the inlet pipe 100 is in its normal operating position. When the inlet pipe 100 deviates from its normal operating position, the axial orientation of the through hole 210 is inclined.

[0036] In some embodiments of this utility model, such as Figure 1 and Figure 4 As shown, the inner wall of the inlet pipe 100 is provided with multiple axially extending ribs 110. The ribs 110 are distributed sequentially at intervals along the circumference of the inlet pipe 100. A liquid passage 111 is formed at the interval between two adjacent ribs 110. Each liquid passage 111 communicates with the liquid passage space 300. When the sphere 400 is in the open position, i.e., when the sphere 400 is at the bottom of the liquid passage space 300, the sphere 400 is supported on the upper end of each rib 110. At this time, the liquid passage space 300 communicates with the lower part of the inlet pipe 100 through each liquid passage 111. When replenishing foaming agent, the foaming agent flows through the through hole 210, the liquid passage space 300, and the liquid passage 111 towards the lower part of the inlet pipe 100.

[0037] Among them, such as Figure 1 , Figure 2 and Figure 3As shown, the bottom surface of the pressure member 200 is shaped like a spherical crown. That is, the bottom of the pressure member 200 is concave upwards with an arc surface, and the through hole 210 penetrates the center of the bottom surface of the pressure member 200. When the ball 400 rolls towards the sealing position, the ball 400 can enter the spherical crown-shaped bottom surface of the pressure member 200. The spherical crown-shaped bottom surface of the pressure member 200 guides the ball 400 to roll towards the through hole 210, ensuring that the ball 400 can roll and seal the through hole 210. Preferably, the maximum outer diameter of the ball 400 is smaller than the maximum inner diameter of the spherical crown-shaped bottom surface of the pressure member 200, allowing the ball 400 to roll into the spherical crown-shaped bottom surface of the pressure member 200. If the maximum outer diameter of the ball 400 is set to be greater than or equal to the maximum inner diameter of the spherical crown-shaped bottom surface of the pressure member 200, then the ball 400 sealing the spherical crown-shaped bottom surface of the pressure member 200 is also equivalent to sealing the through hole 210.

[0038] Among them, such as Figure 3 As shown, a recessed platform 220 is provided on the upper part of the pressure member 200. The recessed platform 220 is formed by sinking downward from the top of the pressure member 200. The upper port of the recessed platform 220 is a constricted shape that gradually narrows from top to bottom. A through hole 210 is formed at the bottom of the recessed platform 220. The through hole 210 connects the recessed platform 220 and the liquid passage space 300. When adding foaming agent, the foaming agent flows through the recessed platform 220 to the through hole 210.

[0039] The pressure member 200 can be installed at any position within the inlet pipe 100. For ease of installation, the pressure member 200 is installed at the end of the inlet pipe 100. The inner wall of the end of the inlet pipe 100 has a shoulder 120. The outer wall of the pressure member 200 can also have a step, with the bottom of the outer wall of the pressure member 200 abutting against the shoulder 120 via the step, thereby limiting the installation depth of the pressure member 200 relative to the inlet pipe 100. A sealing element 230, such as an O-ring, is provided between the pressure member 200 and the end of the inlet pipe 100. The foaming agent can only enter and exit the liquid passage space 300 through the through hole 210.
