Description

Technical Field

[0001] This invention relates to the field of bathroom product technology, and in particular to a smart toilet. Background Technology

[0002] Existing smart toilets typically have a separate water tank for flushing. This tank and the toilet bowl are connected by a notch along the edge for overflow. Therefore, the CL line of the inlet valve must be higher than the bottom surface of the notch, making the inlet valve itself protrude. This means the tank height cannot be reduced, and it occupies design space at the rear of the smart toilet, preventing the toilet seat from being designed lower or flatter. Furthermore, the overflow outlet along the notch requires space to ensure overflow capacity. This also occupies space for the water spray and drying components of the smart toilet seat. Summary of the Invention

[0003] To overcome the shortcomings of the prior art, the present invention provides an intelligent toilet with a larger design space for intelligent components and a low and flat shape.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A smart toilet, comprising:

[0005] The ceramic body includes a device cavity and a toilet cavity. The device cavity is located behind the toilet cavity, and the device cavity and the toilet cavity have a connecting notch at the upper part.

[0006] A water tank is installed inside the equipment cavity. The water tank has a relief slot extending towards the toilet cavity. The relief slot is located inside the notch edge, and the bottom of the relief slot is higher than the overflow water level line.

[0007] An overflow structure is installed inside the water tank. The overflow structure has an overflow inlet and an overflow outlet. The overflow inlet is located at a position that corresponds to the overflow water level line of the water tank, and the overflow outlet extends out of the water tank.

[0008] Furthermore, the overflow structure includes an overflow box and a floating component. The overflow box has an inlet at the top and an outlet at the bottom. The floating component is installed in the overflow box and can be raised and lowered. The floating component is installed in the overflow box and can be raised and lowered by the water level in the overflow box. When the floating component is in the lowest position, the outlet is closed.

[0009] Furthermore, the water tank has a water storage space, and the relief slot extends out from the water tank to one side. The bottom of the relief slot is provided with a partition drain outlet, which extends along the width of the relief slot. The partition drain outlet is used to discharge water flowing back from the relief slot to prevent it from entering the water storage space.

[0010] Furthermore, the bottom of the toilet chamber is connected to the drain pipe through a U-shaped water seal structure, and the overflow outlet and the partition drain outlet are connected to the drain pipe through a pipeline structure, and the connection position is not lower than the water seal water level line of the U-shaped water seal structure.

[0011] Furthermore, the side wall of the water tank has a design clearance opening that extends from top to bottom and faces the inside of the equipment cavity. The design clearance opening is used to provide design space for the smart toilet seat, and the bottom edge of the design clearance opening is higher than the overflow water level line.

[0012] Furthermore, the outer wall of the floating component is provided with several fins, and the outer edge of each fin extends to near the inner wall of the overflow box. The floating component floats vertically by being guided by the fins. The fins are arranged at intervals, and a flow channel is formed between the fins to accommodate the flow of water.

[0013] Furthermore, the floating component is provided with a sealing gasket at the top, and the water inlet has a downwardly protruding lower edge. The sealing gasket is located below the lower edge of the water inlet. When the floating component is in its highest position, the sealing gasket abuts against the lower edge to form a seal on the water inlet.

[0014] Furthermore, the sealing gasket is an annular sealing sheet, and the top of the floating component is provided with an installation position. The installation position includes an upwardly extending protruding section and an outwardly expanding section extending outward from the upper part of the protruding section. There is a gap between the outwardly expanding section and the top surface of the floating component to accommodate the thickness of the annular sealing sheet. The annular sealing sheet is sleeved on the outside of the protruding section and embedded in the gap. The installation position is located below the water inlet and within the vertical projection range of the lower edge. When the floating component is in its highest position, the installation position is inside the water inlet.

[0015] Furthermore, the floating member has a groove cavity opened from bottom to top, and the water outlet has an upper extension section extending upward. The upper extension section is located below the groove cavity. When the floating member is in its lowest position, the upper extension section is located inside the groove cavity, and the top of the upper extension section abuts against the top surface of the groove cavity to form a seal on the water outlet. There is a gap between the inner wall of the groove cavity and the outer wall of the upper extension section to accommodate the passage of water.

[0016] Furthermore, the side wall of the water tank is provided with an overflow installation hole, which is located below the overflow water level line. The overflow structure also includes an inlet pipe and an outlet pipe. The inlet pipe extends upward from the inlet, and the top of the inlet pipe forms the overflow inlet. The outlet pipe is an L-shaped pipe, including a vertical pipe section and a horizontal pipe section. The vertical pipe section connects upward to the outlet, and the horizontal pipe section extends laterally. The middle section of the outer wall of the horizontal pipe section is provided with a protruding retaining edge. The outer wall of the horizontal pipe section is provided with an external thread from the retaining edge to the end and is fitted with a nut. The horizontal pipe section passes through the overflow installation hole, and the end of the horizontal pipe section that passes through the overflow installation hole forms the overflow outlet. By tightening the nut, the wall of the water tank is clamped between the nut and the retaining edge to form a positioning installation of the overflow structure.

[0017] As can be seen from the above description of the present invention, compared with the prior art, the intelligent toilet provided by the present invention has the following advantages:

[0018] 1. By adding an independent overflow structure, the overflow water level can be lowered, allowing for the installation of a lower inlet valve, which in turn enables a lower or flatter smart toilet seat, while also providing more design space for smart components.

[0019] 2. By redesigning the water tank structure, the overflow space is eliminated from the slot, and the design of the overflow port on the side wall of the water tank increases the design space of the smart toilet seat, which facilitates the spatial layout of the water spray body and drying components of the smart seat, and provides a foundation for a better intelligent upgrade design.

[0020] 3. The partition drain outlet set at the trough can discharge backflowing sewage, thereby preventing sewage from flowing into and polluting the water storage space of the water tank.

[0021] 4. The overflow structure is equipped with a floating component that rises and falls according to the water level in the overflow tank. In the non-overflow state, this component seals the outlet, preventing odors from flowing upwards. During overflow, the floating component automatically rises, allowing water to flow through the guide channel, into the recessed cavity, and finally out through the outlet, thus achieving the overflow action. In the event of backflow in the drain pipe, water flows backwards from the outlet into the overflow tank. The floating component will rise to its highest position, blocking the inlet through the sealing gasket and preventing sewage from contaminating the tank's storage space. Attached Figure Description

Detailed Implementation

[0033] The present invention will be further described below through specific embodiments.

[0034] Reference Figures 1 to 10 As shown, an intelligent toilet includes: a ceramic body 1, a water tank 2, an overflow structure 3, and an inlet valve assembly 4.

[0035] The ceramic body 1 includes a device cavity 11 and a toilet cavity 12. The device cavity 11 is located behind the toilet cavity 12, and the device cavity 11 and the toilet cavity 12 are provided with a connecting notch 13 at the upper position.

[0036] Water tank 2 is installed inside equipment cavity 11. Water tank 2 has a clearance slot 21 extending towards toilet cavity 12. The clearance slot 21 is located inside notch 13 and provides clearance space for the installation and passage of cleaning components. The bottom of clearance slot 21 is higher than the overflow water level line. Overflow installation hole 22 is opened on the side wall of water tank 2. Water tank 2 has water storage space. The clearance slot 21 extends out from one side of water tank 2. A partition drain outlet 23 is opened at the bottom of clearance slot 21. The partition drain outlet 23 extends along the width direction of clearance slot 21 and is used to discharge water flowing back from clearance slot 21 to prevent it from entering the water storage space. The side wall of the water tank 2 has a design clearance opening 24 that extends from top to bottom and faces into the equipment cavity 11. The design clearance opening 24 is used to provide design space for the smart toilet seat, and the bottom edge of the design clearance opening 24 is higher than the overflow water level line. Several outwardly extending mounting brackets 25 are provided on the top edge of the water tank 2.

[0037] Overflow structure 3 is installed inside water tank 2. Overflow structure 3 has an overflow inlet and an overflow outlet. The overflow inlet position corresponds to the overflow water level line of the water tank, and the overflow outlet extends out of water tank 2. Overflow structure 3 includes overflow box 31 and floating component 32. The overflow box 31 has an inlet 311 at the top and an outlet 312 at the bottom. Floating component 32 is buoyant and floats inside overflow box 31. When floating component 32 is in its highest position, it closes the inlet 311. In its lowest position, the outlet 312 is closed. A flow channel exists between the floating component 32 and the inner wall of the overflow tank 31 to allow water flow. The water level in the overflow tank 31 drives the floating component 32 to rise and fall. The outer wall of the floating component 32 is provided with several fins 321, each fin's outer edge extending close to the inner wall of the overflow tank 31. The fins 321 guide the floating component 32 to float vertically. The fins 321 are spaced apart, forming a flow channel. The outer wall of the floating component 32 is cylindrical, and the inner wall of the overflow tank 31 is also cylindrical. The fins 321 are evenly arranged around the circumference of the floating component 32, with a gap of 1mm to 3mm between the edge of the fins 321 and the inner wall of the overflow tank 31. The floating member 32 has a sealing gasket 322 on its top. The inlet 311 has a downwardly protruding lower edge 311a. The sealing gasket 322 is located below the lower edge 311a. When the floating member 32 is in its highest position, the sealing gasket 322 abuts against the lower edge 311a to seal the inlet. In a specific embodiment, the sealing gasket 322 is an annular sealing sheet. The floating member 32 has a mounting position 323 on its top. The mounting position 323 includes an upwardly extending protruding section 323a and an outwardly expanding section 323b that expands outward from the upper part of the protruding section 323a. There is a gap between the outwardly expanding section 323b and the top surface of the floating member 32 to accommodate the thickness of the annular sealing sheet. The annular sealing sheet is sleeved on the protruding section 323a and embedded in the gap. The mounting position 323 is located below the inlet 311 and within the vertical projection range of the lower edge 311a. When the floating member 32 is in its highest position, the mounting position 323 is inserted into the inlet 311. The floating member 32 has a recessed cavity 324 opening upwards, and the outlet 312 has an upwardly extending upper extension 312a located below the recessed cavity 324. When the floating member 32 is in its lowest position, the upper extension 312a is within the recessed cavity 324, and the top of the upper extension 312a abuts against the top surface of the recessed cavity 324, forming a seal on the outlet 312. There is a gap between the inner wall of the recessed cavity 324 and the outer wall of the upper extension 312a to allow water to flow through.

[0038] The overflow tank 31 is equipped with an inlet pipe 33 and an outlet pipe 34. The lower end of the inlet pipe 33 is connected to the inlet port 311, and the top of the inlet pipe 33 forms the overflow inlet. The outlet pipe 34 is an L-shaped pipe, including a vertical pipe section 341 and a horizontal pipe section 342. The vertical pipe section 341 is connected upward to the outlet port 312, and the horizontal pipe section 342 extends laterally. The middle section of the outer wall of the horizontal pipe section 342 is provided with a protruding retaining edge 343. The outer wall of the horizontal pipe section 342 is provided with an external thread from the retaining edge 343 to the end and is fitted with a nut 344. The horizontal pipe section 342 passes through the overflow mounting hole 22, and the end of the horizontal pipe section 342 extending out of the overflow mounting hole forms the overflow outlet. By tightening the nut 344, the wall of the water tank 2 is clamped between the nut 344 and the retaining edge 343 to form a positioning installation of the overflow structure 3.

[0039] The bottom of the toilet chamber 12 is connected to the drain pipe 15 through a U-shaped water seal structure 14. The overflow outlet and the partition drain outlet 23 are connected to the drain pipe 15 through a pipeline structure, and the connection position is not lower than the water seal water level line of the U-shaped water seal structure 14.

[0040] The smart toilet of this application features an independent overflow structure 3 with the overflow outlet positioned downwards. This lowers the overflow water level, allowing for the installation of a lower-profile inlet valve assembly 4, and consequently, a lower or flatter smart toilet seat. Furthermore, the lower overflow water level design allows for the creation of a design opening on the side wall of the water tank to accommodate the layout of the smart toilet seat's functional components, thus increasing the design space for the smart toilet seat.

[0041] The water tank 2 is located at the notch 13, and the clearance slot 21 does not need to reserve overflow space. Therefore, it has a larger design space to facilitate the spatial layout of the water spray body and drying components of the smart cover, providing a basis for a better intelligent upgrade design.

[0042] If the toilet chamber 12 becomes blocked, causing sewage to flow back through the relief slot 21, the obstruction drain 23 installed in the relief slot 21 can discharge the backflowing sewage, thus preventing sewage from flowing into and contaminating the water storage space of the water tank 2. The overflow outlet and obstruction drain 23 are connected to the drainage pipe through a pipeline structure at a position not lower than the water seal level of the U-shaped water seal structure 14. This structure design ensures smooth overflow and drainage when the toilet chamber 12 is blocked, preventing sewage backflow.

[0043] The overflow structure 3 is equipped with a floating element 32 that rises and falls according to the water level in the overflow tank 31. In the non-overflow state, the floating element 32 is at its lowest position, located at the upper extension 312a, forming a seal on the outlet 312, thus preventing odors from flowing upwards. When the water level in the tank 2 is higher than the overflow water level line, water flows into the overflow tank 31 through the inlet 311. Under the buoyancy of the water, the floating element 32 floats up, and the water flows through the guide channel into the groove cavity 324, finally being discharged from the outlet 312, thus realizing the overflow action of the tank 2. If backflow occurs in the drain pipe 15, the water flows back into the overflow tank 31 from the outlet 312. The floating element 32 will float to its highest position, thereby blocking the inlet 311 through the sealing gasket 322, preventing sewage from contaminating the water storage space of the tank 2 through the inlet 311.

[0044] The above is only one specific embodiment of the present invention, but the design concept of the present invention is not limited thereto. Any non-substantial modifications made to the present invention using this concept shall be considered as infringing the protection scope of the present invention.
