Description

Technical Field

[0001] This invention relates to the field of toilet technology, specifically to a toilet cleaning robot. Background Technology

[0002] While most smart toilets on the market have some basic cleaning functions, such as bidet, feminine wash, and nozzle self-cleaning, they mainly rely on simple water rinsing to clean the inside of the toilet. This makes it impossible to thoroughly clean every corner of the toilet bowl. Areas such as the upper part of the toilet bowl near the edge and the area below the water seal often become cleaning dead spots, which can easily accumulate dirt and bacteria after long-term use.

[0003] Meanwhile, most smart toilets do not have a dedicated automatic cleaning device for the toilet seat, and can only be manually disassembled and cleaned, which is very inconvenient, especially in public places such as high-speed rail, hospitals or shopping malls, where there is a large flow of people and the toilet is used very frequently. Especially in hospitals, if cleaning is not thorough, it can easily cause the spread of germs and threaten the health of patients and medical staff.

[0004] According to data from the Chinese Center for Disease Control and Prevention, 78% of respondents avoid using public toilet seats. The World Toilet Organization (WTO)'s "2023 Global Transport Hub Hygiene Assessment" shows that 65% of people use toilet paper seat covers, while 42% choose squat toilets. This causes many public toilets to lose their usability and comfort due to hygiene issues, making them less convenient than squat toilets. Therefore, we propose a toilet cleaning robot. Summary of the Invention

[0005] The purpose of this invention is to provide a toilet cleaning robot to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a toilet cleaning robot, comprising a toilet seat, a toilet seat ring, and a toilet lid. A cleaning chamber is slidably provided on the inner side of the toilet lid from the hinged end to the other end. A driving part is provided on the toilet seat for driving the cleaning chamber to move back and forth. The driving part is also used to drive the toilet seat ring and toilet lid to lift at an angle, so that the cleaning chamber moves back and forth and covers the toilet seat ring. A pipeline system is provided on the side wall of the cleaning chamber, leading to the interior and lower surface of the cleaning chamber. Spray holes connected to the pipeline system in the interior and lower surface of the cleaning chamber are used to rinse the toilet seat ring and the inner wall of the toilet seat, respectively. A high-temperature, high-pressure steam generator and a drying device are also provided inside the toilet seat, used to introduce high-temperature steam and hot air into the pipeline system, respectively. A drain hole, conforming to the shape of the upper surface of the toilet seat, is provided below the cleaning chamber to drain overflowing water.

[0007] Preferably, the toilet is also equipped with a changing device for changing the angle of the water jet from the nozzle, which causes the water jet to be shot onto the toilet seat surface from different angles.

[0008] Preferably, the conversion device includes a guide plate disposed on the outer ring of the lower surface of the toilet seat. Several guide plates are evenly distributed at intervals. The guide plates are made of shape memory metal material, with one end fixed and the other end free. At least one ring of the spray nozzle corresponding to the pipeline system is directly opposite the guide plate. The guide plate bends and deforms under temperature changes, so that the water flow from the spray nozzles continuously changes the angle and is shot onto the lower surface of the toilet seat through the guide plate.

[0009] Preferably, the free end of the guide plate initially directs the water flow from the spray nozzle to the outer end of the toilet seat, and bends towards the other end of the toilet seat as the temperature rises. The guide plate on the outer end side of the toilet seat bends symmetrically from the middle of that side to both sides.

[0010] Preferably, the critical temperature of the guide plate at different positions is different, and it increases from the outer end of the toilet seat to the other end.

[0011] Preferably, the water flow guidance areas formed on the inner surface of the toilet seat by the two adjacent guide plates have an overlapping portion.

[0012] Preferably, in the water flow guiding areas of two adjacent guide plates, the guiding areas of the preceding guide plate and the guiding areas of the following guide plate overlap during the flow guiding process.

[0013] Preferably, the nozzles are all angled toward the area to be rinsed.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] This invention features a cleaning chamber on the toilet that can move and completely enclose the toilet seat, enabling 360° comprehensive cleaning. Combined with high temperature, it can sterilize while cleaning, effectively improving the health threats caused by inadequate toilet cleaning.

[0016] This invention uses a guide plate under the toilet seat to redirect the water flow from the spray nozzle, allowing it to act more laterally on the lower surface of the toilet seat, thus improving the cleaning of stains.

[0017] This invention uses a guide plate to set different temperature gradients to achieve a phased and continuous change in direction, so that it can not only rinse at different positions, but also form a continuous flow, which can better direct the flow of dirt. Attached Figure Description

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 This invention provides a technical solution: a toilet cleaning robot, comprising a toilet seat 3 and a toilet gasket 2 connected to a toilet seat 1. Unlike traditional direct hinged or shaft-connected methods, in this solution, one end of the toilet gasket 2 extends into the toilet seat 1 and connects to a drive unit, allowing a first flip motor 10 in the drive unit to independently drive the toilet gasket 2 to flip and rise or fall. Similarly, one end of the toilet seat 3 is hinged or shaft-connected to the toilet seat 1 and also connected to the drive unit, and a second flip motor 10 in the drive unit... Under the control of machine 11, automatic opening and closing (flipping) is achieved. The two sides of the toilet seat 3 extend downwards to form sidewalls, and the cleaning chamber 4 is slidably connected through the extended sidewalls. The geared motor 12 in the drive unit drives the synchronous belt 13. The synchronous belt 13 is equipped with a linear guide rail 14, which is slidably connected to the outer wall of the cleaning chamber 4. With the linear guide rail 14, the cleaning chamber 4 and the toilet seat 3 can slide without contact. Driven by the geared motor 12, the cleaning chamber 4 moves in the inward and outward directions, with the inner end being... Near the end connected to the toilet seat 3, with the outer end opposite to the inner end, the cleaning chamber 4 is a hollow chamber with one open end. A piping system 5 is installed on the inner wall of the cleaning chamber 4, and spray holes 6 are opened on the inner side wall and the outer bottom wall of the cleaning chamber 4. The spray holes 6 on the inner wall of the cleaning chamber 4 are used to rinse the upper, side, and lower surfaces of the toilet seat 2, achieving a 360° comprehensive rinse. The spray holes 6 on the outer bottom wall of the cleaning chamber 4 are used to rinse the inner wall of the toilet. A high-temperature, high-pressure steam generator 7 is also installed inside the toilet seat 1. The drying device 8 and the high-temperature and high-pressure steam generator 7 are connected to the pipeline system 5. High-temperature and high-pressure steam or water is introduced into the toilet through the pipeline system 5. The drying device 8 is directly connected to the toilet and dries the toilet when the toilet lid 3 is closed. The cleaning chamber 4 is provided with a drain hole that matches the shape of the upper surface of the toilet seat. The drain hole will remove the overflow water. That is, the cleaning chamber 4 is set with a U-shaped structure and a drain hole is opened on the structure. When water overflows from the upper surface of the toilet seat 1 due to cleaning, the overflow water will be removed to avoid the overflow affecting the floor.

[0036] Specifically, after using the toilet (flushing), the toilet seat 3 is in a vertical position. A command is sent to the controller via a button (or automated control, such as sensors), activating the second flip motor 11 in the drive unit to flip the toilet seat 3 horizontally. The flip angle is approximately 80°, but can also be 75° or 70°. In this state, the toilet seat 3 is not fully closed. Then, the reduction motor 12 drives the synchronous pulley, which in turn drives the synchronous belt 13 to move the washing chamber 4 outwards on the linear guide rail 14, thus making room for the toilet seat 2. Driven by the first flip motor 10, the toilet seat 2 flips upwards by approximately 15°, or can also be 20°. After the toilet seat 2 rises, the reduction motor 12 activates the washing... The chamber 4 moves inward and gradually places the toilet seat 2 inside the cleaning chamber 4. The outer end of the inner wall of the cleaning chamber 4 contacts the upper surface of the toilet seat 2, and the inner end of the inner wall of the cleaning chamber 4 contacts the lower surface of the toilet seat 2 to form a fixed state. After the cleaning chamber 4 has completely moved back, the second flip motor 11 and the first flip motor 10 are driven simultaneously to make the toilet lid 3 and the toilet seat 2 flip downward about 10° in sync. Then the toilet lid 3 is closed, and the toilet seat 2 is in an inclined state. Then the steam high temperature and high pressure generator 7 receives the instruction to perform high temperature and high pressure cleaning on the entire toilet seat 2, the toilet surface (the surface on the toilet seat 1 that is in contact with the lower surface of the toilet seat 2), and the inner wall of the toilet. Finally, the drying device 8 dries the toilet.

[0037] When using the high-temperature and high-pressure steam generator 7 for high-temperature cleaning, there are two specific scenarios. The first scenario involves introducing a small amount of high-temperature and high-pressure steam to soften any hardened stains that may be present on the toilet seat 2 or toilet seat 1. After a certain interval, water is introduced for rinsing. The second scenario involves directly introducing high-temperature and high-pressure water for rinsing. Relatively speaking, the first scenario is more water-saving.

[0038] See Figure 5 , Figure 8 , Figure 9 , Figure 10 , Figure 11 and Figure 12 Toilet seat covers mainly come in two structures, one of which is... Figure 8 The toilet seat 2 shown has a flat lower surface and is equipped with legs. With this design, the lower surface of the toilet seat 2 can be directly cleaned by a water flow that is almost parallel to the lower surface of the toilet seat 2 generated by the side spray nozzles 6, effectively removing stains. Another type is... Figure 9 As shown, the lower surface of the toilet seat 2 is hollow, with both edges protruding downwards, and the two edges are connected by rounded corners (right angles are more prone to trapping dirt). In the second method, the spray nozzle 6 cannot produce a nearly parallel flushing motion; it can only... Figure 11 direct rinsing or Figure 12The angle of the water flow increases as it approaches the edge. With a fixed rinsing angle, there are gaps between adjacent water jets. A single water jet has a limited range of action on the rinsing surface. The larger the angle, the smaller the lateral impact force. If rinsing from the front, only the impact force can remove some of the dirt. Some dirt with strong adhesion is difficult to rinse off. Therefore, a device that changes the angle of the water jet from the nozzle 6 can better clean the dirt and also cover more comprehensively.

[0039] Specifically, the switching device can be a micro-nozzle, which can be adjusted in range to achieve the above actions. Because the piping system 5 corresponds to a large number of nozzles 6, using micro-nozzles would not only be costly but also prone to clogging. Therefore, the switching device uses another simple device, including but not limited to a guide plate 9. The guide plate 9 is arc-shaped, conforming to the transition between the lower surface and edge of the toilet seat 2. Figure 10 The guide plate 9 is made of shape memory metal, with one end fixed and the other end being a free end in a non-fixed state. Under temperature changes, the free end of the guide plate 9 can move completely to the left or right. Figure 9 From a certain perspective, the initial state can be a bent state to one side, and then change to the other side. Guided by the guide plate 9, the water flow can be directed away from the front or at a large angle, and then flush at an angle approximately parallel to the lower surface of the toilet seat 2. Because the guidance results in less momentum loss of the water flow compared to direct impact, the lateral impact force is more conducive to cleaning stubborn stains. Furthermore, because the water flow constantly changes direction, the same position on the lower surface of the toilet seat 2 can be impacted from various directions, which is more conducive to cleaning stubborn stains. This is because stains form different shapes when they are formed. A certain direction may form a smooth shape, which is not conducive to rinsing in that direction, while changing the direction makes it easier to clean.

[0040] See Figure 3 In the flushing state, the toilet seat 2 is tilted at a small angle. During flushing, the water flow will flow along the toilet seat 2 from the outer end to the inner end. Therefore, the preferred solution is to first flush the outer end of the toilet seat 2 and then change towards the inner end, thereby forming a sweeping motion along the natural flow direction of the water. On the outer end, there is a symmetrical design with the middle part of the side curving to both sides.

[0041] Furthermore, along the inclined direction of the toilet seat 2, the water flows naturally downwards. The sequential changes in the flushing angle allow for better removal of the flushed stains in a downward direction, i.e., from the outer end to the inner end. After the first guide plate 9 sweeps the water, the second guide plate 9 follows, creating a continuous flow that effectively cleans the toilet. Figure 13 As shown;

[0042] Furthermore, such as Figure 14As shown, the rinsing areas formed by the water flow of two adjacent guide plates 9 overlap to facilitate better transmission. At the same time, the two also have an intersection in sequence. That is, it is not that the first guide plate 9 completes the deformation process before the other begins, but rather that the second guide plate 9 begins to bend during the deformation process of the first one. In this way, the first one can counteract the reverse rinsing of the rearward guide plate 9.

[0043] See Figure 15 As a specific implementation method of the guide plate 9 and the nozzle 6, the guide plate 9 can be deformed to guide the different nozzles 6 to generate water flow in different directions for rinsing. The solution is simple and easy to implement. At the same time, because the guide plate 9 itself is movable, its edges are not prone to dirt accumulation, making it easy to rinse.
