Description

Technical Field

[0001] The present invention relates to the technical field of intelligent bathroom equipment, and in particular to a closed-loop flushing toilet cover and a toilet. Background Art

[0002] Most smart toilet lids or smart toilets (or toilets) have buttocks washing (buttocks washing) and female washing (female washing) functions. The corresponding water spraying devices are usually composed of one or more linear nozzles, which spray single or multiple linear water streams or water columns when working, directly acting on the part of the human body to be cleaned.

[0003] However, this type of toilet seat that uses linear water spray has a poor cleaning effect. For example, when the linear water flow hits the surface of human waste (viscous fecal waste), the impact force it generates can easily cause the waste and sewage to splash and spread around the water flushing point (radially)! Even if the nozzle position is adjusted, the body trajectory is moved, or the water pressure is adjusted, the radial splashing and spreading of waste cannot be changed. The splashed and spread sewage and waste will remain around the cleaning area (such as the skin, wrinkles, hair roots and clothes around the cleaning area. In particular, due to the body structure of men, the surface of their scrotum is more contaminated by the splashed feces and sewage, and it is difficult for the subsequent water flow to effectively remove it). At the same time, the remaining dirt may also cause bacteria to grow in the female private parts, bringing potential hygiene and health risks, causing many adverse effects and fears in the user's mind, and unwilling to use it again! It can be seen that the existing toilet seat has a major problem of poor cleaning effect.

[0004] Therefore, the market urgently needs an intelligent toilet seat water spraying technology that can solve the problem of sewage and dirt splashing and diffusion from the nozzle structure and fluid mechanics principles, so as to significantly improve the cleaning effect and efficiency. Summary of the Invention

[0005] The embodiment of the present invention provides a closed-loop flushing toilet seat and a toilet, so as to solve the problem that the existing toilet seat has a poor cleaning effect.

[0006] An embodiment of the present invention provides a closed-loop flushing toilet seat, comprising: a toilet seat cover, a chamber, a water pump, a telescopic water spray pipe, and a water divider, wherein the chamber is disposed within the toilet seat cover, the water pump, the telescopic water spray pipe, and the water divider are disposed within the chamber, the water pump is connected to one end of the telescopic water spray pipe, the other end of the telescopic water spray pipe is a nozzle opening, and the water divider is disposed at the nozzle opening;

[0007] The nozzle and the water distributor are provided with a linear water flow port and an annular water curtain port, and the annular water curtain port is arranged around the linear water flow port;

[0008] When the closed-loop flushing toilet lid is in operation, when the telescopic water spray pipe extends from the chamber to a preset position, the linear water flow port sprays a linear water flow, and the annular water curtain port sprays an annular water curtain, so that the waste flushed by the linear water flow is surrounded by the annular water curtain in a closed loop and falls downward with the water flow;

[0009] After the closed-loop flushing toilet lid finishes the flushing state, the water distributor stops spraying water, and the telescopic water spray pipe shrinks from the preset position to the shrinkage chamber.

[0010] Preferably, a support column is further provided under the water divider, and the water divider is fixed to the nozzle port through the support column. The linear water flow port is a circular hole arranged in the center of the water divider, and the annular water curtain port is an annular gap between the water divider and the nozzle port when the water divider is arranged at the nozzle port.

[0011] Preferably, the water outlet size of the linear water flow port is smaller than the water inlet size of the linear water flow port; the water outlet size of the annular water curtain port is larger than the water inlet size of the annular water curtain port.

[0012] Preferably, an annular platform is further provided on the inner side of the nozzle opening, and the annular platform is adapted to the water distributor, and the water distributor comprises a panel, a hollow column nut and a bolt, the panel and the hollow column nut are integrated, and the bolt and the hollow column nut are detachably connected;

[0013] In which, the hollow column nut is provided with multiple water inlet holes near the panel position, the linear water flow outlet is provided at the center of the panel, and the telescopic water spray pipe is connected with the linear water flow outlet through the water inlet hole; the annular water curtain outlet is an annular gap from horizontal to vertical provided between the annular platform and the panel.

[0014] Preferably, a pressure release chamber is provided at the annular gap from the horizontal to the vertical direction, and the angle from the horizontal to the vertical direction is greater than, less than or equal to 90 degrees.

[0015] Preferably, the diameter of the annular water curtain opening is 1 cm to 10 cm, preferably 3 cm to 4 cm, and the shape of the annular water curtain opening is one of circular, elliptical, and polygonal.

[0016] Preferably, the pressure of the water pumped out from the water pump is from low to high.

[0017] Preferably, it also includes at least one of a heating water purifier, an intelligent control system, a heater and a ring cover heater, and the intelligent control system is electrically connected to the water pump, the heating water purifier, the heater and the ring cover heater.

[0018] Preferably, the intelligent control system includes a circuit board, program software and a sensor, and the intelligent control system is used to execute various preset functions of the closed-loop flushing toilet lid.

[0019] An embodiment of the present invention provides a toilet, including the above-mentioned closed-loop flushing toilet cover.

[0020] In this embodiment of the present invention, linear water flow outlets and annular water curtain outlets are provided on the nozzle and manifold. The annular water curtain outlet surrounds the linear water flow outlet, so that the annular water curtain ejected simultaneously by the manifold forms a circular water curtain wall that surrounds the linear water flow in the center. This fundamentally restricts the radial diffusion of wastewater and dirt during the flushing process. Wastewater is effectively confined to the core flushing area and carried away, eliminating contamination of the skin, wrinkles, and hair roots surrounding the cleaning area, significantly improving cleaning effectiveness. Even if part of the annular water curtain spray contacts the body, the water that diffuses outward is clean water and does not contaminate other parts of the body. Furthermore, this more thorough cleaning reduces the risk of bacterial residue and growth, promoting greater hygiene and health. This unprecedented dual-flow cleaning method provides users with a more refreshing, clean, and comfortable experience, improving product satisfaction. The manifold design is feasible and easy to implement, can be manufactured using established processes, and can be integrated into existing smart toilet lid nozzle systems, reducing implementation complexity.

DETAILED DESCRIPTION

[0039] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0040] The terms "first," "second," and the like in the embodiments of the present invention are used to distinguish similar objects and are not necessarily used to describe a specific order or precedence. In addition, the terms "including," "having," and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or apparatus that includes a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to the process, method, product, or apparatus.

[0041] The embodiment of the present invention provides a closed-loop flushing toilet lid, such as Figures 1 to 15 As shown, it includes: water distributor 1, nozzle 2, telescopic water spray pipe 3, telescopic power pipe 4, toilet cover 5, toilet seat cover 6, warm air vent 7, key switch 8, chamber 9, intelligent control system 10, heater 11, water pump 12, heating water purifier 13, chamber housing 14, power cord 15, and water inlet pipe 16. The water distributor 1 and nozzle 2 can be produced in two parts or as a single piece through 3D printing.

[0042] The chamber 9 serves as a mounting base and is disposed at the bottom of the toilet seat cover 6. The toilet upper cover 5 fits with the toilet seat cover 6 and covers the top of the toilet seat cover 6. Components such as the water distributor 1, the nozzle 2, the telescopic water spray pipe 3, the telescopic power pipe 4, the heater 11, and the water pump 12 can be disposed in the chamber 9.

[0043] The water pump 12 is connected to one end of the telescopic water spray pipe 3, and the other end of the telescopic water spray pipe 3 is a nozzle port 23. The water distributor 1 is arranged at the nozzle port 23. The nozzle port 23 and the water distributor 1 are provided with linear water flow ports (including a linear water flow outlet 17A and a linear water flow inlet 17B) and an annular water curtain port (including an annular water curtain outlet 18A and an annular water curtain linear inlet 18B or an annular water curtain corner inlet 18C). The annular water curtain port is arranged around the linear water flow port. The inner diameter of the annular water curtain port can be 1 cm to 10 cm, preferably set to 4 cm to form an annular closed barrier, and the barrier range is the best state for most people. In this way, the water distributor 1 is arranged behind the nozzle port 23 and can simultaneously spray two water flows: one is a linear water flow and the other is an annular water curtain, and the linear water flow is located in the center of the annular water curtain.

[0044] The intelligent control system 10 is electrically connected to the telescopic power tube 4, the pushbutton switch 8, the water pump 12, the heating and purifying device 13, the air heater 11, and the seat heater. The seat heater is pre-embedded in the toilet seat 6 to heat the seat. The heating and purifying device 13 is connected to the water pump 12; the warm air vent 7 is connected to the air heater 11 via an air duct. The intelligent control system 10 receives signals from the pushbutton switch 8 or voice commands and coordinates the timing of the drying modules of the water pump 12, the heating and purifying device 13, and the air heater 11 to execute the various preset functions of the closed-loop flushing toilet seat.

[0045] Preferably, the intelligent control system 10 may include a circuit board, program software and a sensor, and the intelligent control system 10 is used to execute various preset functions of the closed-loop flushing toilet lid.

[0046] In one example, when the closed-loop flushing toilet lid is in working state, when the telescopic water spray pipe 3 extends from the chamber 9 to a preset position, the linear water flow outlet sprays out a linear water flow, and the annular water curtain outlet sprays out an annular water curtain, so that the dirt flushed by the linear water flow is surrounded by the annular water curtain closed loop and falls down with the water flow.

[0047] Specifically, when the telescopic water spray pipe 3 extends from the chamber 9 to clean the buttocks, the annular water curtain simultaneously ejected from the water distributor 1 forms an annular water curtain wall that surrounds the linear water flow in the center. This allows the dirt washed by the linear water flow to be enclosed in a closed loop by the annular water curtain wall and fall downward with the water flow, preventing it from spreading to other parts of the body. This reduces the risk of the linear water flow spreading dirt and contaminating other areas when washing the buttocks.

[0048] In one example, after the closed-loop flushing toilet lid ends the flushing state, the water distributor 1 stops spraying water, and the telescopic water spray pipe 3 is driven by the telescopic power pipe 4 to retract from the preset position to the retraction chamber.

[0049] The specific workflow can be described as follows: the user presses the button switch 8 or sends a voice command to the intelligent control system 10, which activates the telescopic power tube 4 to push the telescopic water spray pipe 3 out of the chamber 9. At the same time, the system activates the water pump 12 to extract the heated water. The water is pressed into the nozzle 2 through the telescopic water spray pipe 3 and is finally divided into two coaxial streams (inner and outer) through the two water outlets (the middle circular hole and the edge annular gap) of the water distributor 1 at the top of the nozzle 2. The middle circular hole sprays a linear water flow to flush the waste. The annular water curtain sprayed from the annular gap surrounds the waste flushed by the linear water flow and drops it into the toilet. After the flush is completed, the telescopic water spray pipe 3 retracts into the chamber 9, and the heater 11 outputs hot air through the warm air outlet 7 to dry the user's buttocks.

[0050] In this embodiment, linear water flow outlets and annular water curtain outlets are provided on the nozzle and manifold. The annular water curtain outlet surrounds the linear water flow outlet, so that the annular water curtain ejected simultaneously by the manifold forms a circular water curtain wall that surrounds the linear water flow in the center. This fundamentally restricts the radial diffusion of wastewater and dirt during the flushing process. Wastewater is effectively confined to the core flushing area and carried away, eliminating contamination of the skin, wrinkles, and hair roots surrounding the cleaning area, significantly improving cleaning effectiveness. Even if part of the annular water curtain spray contacts the body, the water that diffuses outward is clean water and does not contaminate other parts of the body. Furthermore, this more thorough cleaning reduces the risk of bacterial residue and growth, promoting greater hygiene and health. This unprecedented dual-flow cleaning method provides users with a more refreshing, clean, and comfortable experience, improving product satisfaction. The manifold design is feasible and easy to implement, can be manufactured using established processes, and can be integrated into existing smart toilet lid nozzle systems, reducing implementation complexity.

[0051] Figure 1 This is a plan view of a closed-loop flushing toilet seat. Figure 2 The telescopic water spray pipe 3 of the closed-loop flushing toilet lid is extended. The telescopic power pipe 4 can be driven by a motor to push the telescopic water spray pipe 3 to slide out and retract.

[0052] Figure 3 This is a side view of a closed-loop flush toilet seat. Figure 4 Side view of the telescopic spray pipe of the closed-loop flush toilet lid after extension. Figure 3 The corresponding state is the closed-loop flushing toilet lid storage state, in which the telescopic water spray pipe 3 is completely retracted into the chamber 9. Figure 4 The closed-loop flushing toilet lid is in working state, and the telescopic water spray pipe 3 is extended at an inclined angle, which can reduce interference during use.

[0053] Figure 5 Schematic diagram of the telescopic spray pipe, nozzle and water distributor of a closed-loop flushing toilet lid.

[0054] In this example, the telescopic power tube 4 and the telescopic water spray pipe 3 are meshed and arranged, and the telescopic power tube 4 pushes the telescopic water spray pipe 3 to extend and retract. The water inlet end of the telescopic water spray pipe 3 is connected to the water inlet pipe 16, and the water outlet end, that is, the nozzle mouth, can be provided with a nozzle 2. A water divider 1 is provided at the top of the nozzle 2. The water divider 1 has a linear water flow outlet 17A and an annular water curtain outlet 18A. The linear water flow outlet 17A is opened at the center position of the water divider 1, and the annular water curtain outlet 18A is opened at the outer edge position of the water divider 1.

[0055] Figure 6 This is a schematic diagram of the annular water curtain port and linear water flow port of a closed-loop flushing toilet lid. Figure 6It can be a top view of a double water outlet, including: water divider 1, nozzle 2, linear water outlet 17A, and annular water curtain outlet 18A. Among them, the water divider 1 at the top of the nozzle 2 has two apertures, one is a central circular hole (the top outlet is the linear water outlet 17A), and the other is an annular gap (the top outlet is the annular water curtain outlet 18A). The two apertures divide the toilet cleaning water flow into two inner and outer streams. The dual flow channels are independently optimized. The circular hole water flow flushes dirt, and the annular gap water flow forms a water curtain to wrap the circular hole water flow and make the flushed dirt fall off without contaminating the body.

[0056] It should be noted that the circular hole can be a single hole or multiple holes; the annular gap can be a single annular gap or multiple annular gaps, but the annular gap must form a closed water flow loop, which will not be elaborated here.

[0057] It should also be noted that the linear water flow and the annular water curtain can be formed by splitting the flow from a single pipe or by separate pipes. For example, a separate pipe connected to a water pump can be provided below the linear water outlet 17A to supply water independently, thereby still ensuring that the water pressure of the linear water flow and the water pressure of the annular water curtain are completely different.

[0058] Preferably, the size of the water outlet of the linear water flow outlet (i.e., the linear water flow outlet 17A) is smaller than the size of the water inlet of the linear water flow outlet (i.e., the linear water flow inlet 17B); the size of the water outlet of the annular water curtain outlet (i.e., the annular water curtain outlet 18A) is larger than the size of the water inlet of the annular water curtain outlet (i.e., the annular water curtain linear inlet 18B).

[0059] In this embodiment, see Figure 7 , Figure 7 This is a cross-sectional view of the annular water curtain port and linear water flow port of a closed-loop flush toilet lid. The figure also shows the linear water flow inlet 17B, the annular water curtain linear water inlet 18B, and the lower space 19 of the nozzle port. By setting the size of the linear water flow port's outlet (i.e., the linear water flow outlet 17A) to be smaller than the size of the linear water flow port's inlet (i.e., the linear water flow inlet 17B), the linear water flow inlet 17B is made into a gradually converging circular hole to increase the flow rate of the linear water flow; and by setting the size of the annular water curtain port's outlet (i.e., the annular water curtain outlet 18A) to be larger than the size of the annular water curtain port's inlet (i.e., the annular water curtain linear water inlet 18B), the annular water curtain port is made into a gradually expanding annular gap to reduce the annular water curtain flow rate.

[0060] In addition, see Figure 8 , Figure 8This diagram illustrates the space below the nozzle opening of a closed-loop flushing toilet lid. It includes nozzle 2, space 19 below the nozzle opening, and nozzle opening 23. As can be seen from the diagram, a single stream of water flows into nozzle opening 23. Space 19 below the nozzle opening lacks any other piping, nor does it divert the water flow. This single stream of water is diverted at nozzle opening 23. This simplifies the piping structure, saves materials, and reduces production steps.

[0061] Preferably, a support column 20 is further provided below the water divider 1, and the water divider 1 is fixed to the nozzle port 23 through the support column 20. The linear water flow port is a circular hole arranged in the center of the water divider, and the annular water curtain port is an annular gap between the water divider and the nozzle port when the water divider is arranged at the nozzle port.

[0062] In this embodiment, see Figure 9 and Figure 10 , Figure 9 This is a schematic diagram of the bottom of the water distributor and the support column of the closed-loop flush toilet lid. Figure 10 This is a cross-sectional view of the bottom of the manifold and support column of a closed-loop flush toilet lid. The manifold 1 is secured to the telescopic spray pipe 3 near the nozzle opening 23 by support column 20. The diameter of the linear water outlet 17A is smaller than that of the linear water inlet 17B. Based on the principles of fluid mechanics, the gradually shrinking aperture increases water velocity and thus boosts flushing water pressure. Support column 20, located outside the linear water inlet 17B, primarily serves to connect the manifold to the nozzle.

[0063] It should be noted that the support column 20 can be a screw or a welding point to serve as a connecting piece.

[0064] In another embodiment, see Figures 11 to 13 , an annular platform is also provided on the inside of the nozzle mouth, which is adapted to the water distributor 1. The water distributor 1 includes a panel, a hollow column nut 28 and a bolt 25. The panel and the hollow column nut 28 are integrated, and the bolt 25 and the hollow column nut 28 are detachably connected;

[0065] Among them, a plurality of hollow column water inlet holes 24 are arranged near the panel position of the hollow column nut 28, the linear water flow port is arranged in the center of the panel, and the telescopic water spray pipe 3 is connected with the linear water flow port through the hollow column water inlet hole 24; the annular water curtain port is an annular gap with a preset angle from horizontal to vertical set between the annular platform and the panel.

[0066] Figure 11 This is a schematic diagram of the space below the nozzle of another type of closed-loop flushing toilet lid. Figure 12 This is a schematic diagram of another type of water distributor for closed-loop flushing toilet lids. Figure 13A cross-sectional view of the bottom and annular platform of another type of water distributor for a closed-loop flush toilet seat.

[0067] Specifically, the annular platform can be the annular water dividing plate 27 at the nozzle mouth, and the panel of the water divider 1 can be set at the position of the annular water dividing plate 27 at the nozzle mouth, and be adapted to the annular platform (i.e., the annular water dividing plate 27 at the nozzle mouth), so that a "horizontal to vertical annular gap" is formed between the panel of the water divider 1 and the annular water dividing plate 27 at the nozzle mouth. The annular gap is set at a preset angle, and the water flow inlet position of the annular gap is the annular water curtain corner inlet 18C according to the water flow direction, and the water flow outlet position is the annular water curtain outlet 18A. The flowing water in the telescopic water pipe 3 can directly enter the annular gap through the annular water curtain corner inlet 18C, and spray out the annular water curtain through the annular water curtain outlet 18A.

[0068] Inside the nozzle opening, opposite the annular water divider plate 27, a lower bolt opening 26 is provided. This opening 26 mates with a bolt 25, providing an annular securing channel for the bolt 25. The bolt 25 and hollow column nut 28 can be threadedly connected at this location. This securing effect of the lower bolt opening 26 reduces the possibility of bolt 25 moving, thereby enhancing the stability of the connection between the bolt 25 and the hollow column nut 28.

[0069] In addition, a plurality of hollow column water inlet holes 24 are provided near the panel position of the hollow column nut 28, and the flowing water in the telescopic water spray pipe 3 can flow into the circular hole in the center of the water distributor 1 through the plurality of hollow column water inlet holes 24 on the hollow column nut 28, and spray out a linear water flow from the linear water flow outlet 17A.

[0070] Among them, the size of the annular water curtain outlet (i.e., the annular water curtain outlet 18A) is set to be larger than the size of the annular water curtain inlet (i.e., the annular water curtain corner inlet 18C), so that the annular water curtain outlet is a gradually expanding annular gap to reduce the flow rate of the annular water curtain.

[0071] Preferably, a pressure release chamber 29 is provided at the annular gap from the horizontal to the vertical direction, and the angle from the horizontal to the vertical direction is greater than, less than or equal to 90 degrees.

[0072] In this embodiment, a first groove is provided on the panel of the water distributor 1, and a second groove is provided on the annular water distribution plate 27 at the nozzle outlet. The first and second grooves are arranged opposite each other. When the panel of the water distributor 1 is placed on the annular water distribution plate 27 at the nozzle outlet, the first and second grooves form a pressure release chamber 29. The pressure release chamber 29 is located in the horizontal and vertical annular gap between the panel of the water distributor 1 and the annular water distribution plate 27 at the nozzle outlet. In this way, the novel and unique pressure release chamber 29 not only buffers the water flowing through the annular gap, but also evenly and redistributes the water flow, so that the water flows slowly and evenly out through the annular water curtain outlet 18A, thereby forming a more ideal annular water curtain.

[0073] It should also be noted that because the spatial dimensions of the horizontal gap are very small, a gap control point 30 is provided at the outer edge of the horizontal gap. In order not to block the water flow, the gap control point 30 is only a tiny dot. There should be no less than three evenly distributed gap control points 30 in the horizontal gap surface, and the shapes and sizes of no less than three gap control points 30 should be consistent. The gap control point 30 is provided to make the spatial dimensions of the horizontal gap and the vertical gap more precisely controlled and the water flow more uniform.

[0074] In addition, the angle of the annular gap from horizontal to vertical can be greater than, less than or equal to 90 degrees. In this way, the annular gap diffuses from horizontal to vertical or oblique, and the water inlet diameter is still smaller than the water outlet diameter, thereby further spraying out the blocking effect of the annular water curtain, reducing the spread of dirt and the splashing of the annular water flow.

[0075] Preferably, the shape of the annular water curtain port is one of circular, elliptical, and polygonal. Different shapes of annular water curtain ports can be suitable for different usage scenarios and user needs, thereby improving the adaptability of the closed-loop flushing toilet lid.

[0076] Preferably, the pressure of the water pumped out from the water pump is from low to high, so as to reduce diffusion caused by excessive initial pressure.

[0077] Figure 14 This is a schematic diagram of the annular water curtain and linear water flow sprayed from a closed-loop flushing toilet lid. For example, a telescopic water spray pipe 3 connects to the nozzle 2, directly supplying water to the nozzle 2. The nozzle 2's outlet sprays two internal and external streams of water: an annular water curtain 21 and a linear water stream 22. The annular water curtain 21 confines the sewage and dirt sprayed by the linear water stream 22, preventing them from scattering. The annular water curtain 21 (with an inner diameter of 1 to 10 cm, preferably 4 cm) forms a closed annular barrier; while the linear water stream 22 is responsible for flushing and stripping dirt, providing a cleansing effect. The linear water stream 22 flushes dirt within the inner diameter of the annular water curtain 21. After being wrapped and constrained by the annular water curtain, the dirt falls downward into the toilet bowl.

[0078] The embodiment of the present invention provides a toilet, comprising a toilet body 31 and the above-mentioned closed-loop flushing toilet cover, such as Figure 15 shown. Figure 15 This is a diagram of a closed-loop flushing toilet lid and toilet combination. The toilet's functional components are primarily installed in the lid. The smart toilet lid and toilet are separate and hinged together when combined.

[0079] It should be noted that the implementation method of the above-mentioned closed-loop flushing toilet lid embodiment is also applicable to the embodiment of this toilet and can achieve the same technical effect, which will not be repeated here.

[0080] It should be noted that, in this article, the terms "comprise", "include" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
