Description

Technical Field

[0001] This invention relates to the technical field of toilet cleaning devices, and in particular to a self-cleaning toilet. Background Technology

[0002] When people use the toilet, urine often splashes out of the toilet bowl. This not only causes unpleasant odors inside the toilet, but also easily promotes bacterial growth and reduces user satisfaction.

[0003] To ensure the cleanliness and hygiene of toilets, it is usually necessary to employ cleaning staff to clean them regularly. However, this method not only increases labor costs but also results in situations where cleaning staff are not available to clean in a timely manner. Summary of the Invention

[0004] In view of the above-mentioned problems in the prior art, the present invention provides a self-cleaning toilet, the purpose of which is to achieve automatic cleaning of the floor, reduce manual labor, and lower the labor cost of toilet cleaning operations.

[0005] To achieve the above-mentioned objectives, the technical solution adopted by this invention is as follows:

[0006] A self-cleaning toilet is provided, comprising: a mobile trolley movably installed within the toilet body; a drive unit for driving the mobile trolley to reciprocate linearly along a fixed path within the toilet body; a spray assembly installed on the mobile trolley for spraying cleaning liquid onto the floor of the toilet body; a scraper installed on the mobile trolley for scraping away water stains from the floor of the toilet body; a sterilization lamp installed on the mobile trolley for providing ultraviolet irradiation to the floor of the toilet body; and a water tank disposed within the toilet body for receiving water stains scraped away by the scraper.

[0007] Furthermore, the toilet also includes: a guide rail, mounted on the toilet body, on which a mobile trolley is movably mounted; a water collection trough, extending along the length of the scraper and located on the floor of the toilet body, connected to a water storage tank for receiving water; a cover plate, hinged to the toilet body for sealing the water collection trough; a rotary motor; a first connecting rod hinged to the cover plate; and a second connecting rod hinged at one end to the first connecting rod and at the other end to the output shaft of the rotary motor; the output shaft of the rotary motor rotates forward / reverse, causing the cover plate to rotate around the hinge shaft, thereby opening / closing the water collection trough.

[0008] Furthermore, the scraper is positioned along the width of the toilet body, and the moving trolley reciprocates in a straight line along the length of the toilet body.

[0009] Furthermore, the toilet also includes: at least two rotating rollers, parallel to the ground of the toilet body, both rotatably mounted on a mobile trolley; several mounting grooves arranged in an array along the circumferential direction of the rotating rollers, the depth direction of the mounting grooves extending along the radial direction of the rotating rollers, and several scrapers slidably mounted in the grooves; a spring, disposed between the scrapers and the rotating rollers, for providing a tendency for the scrapers to move in a direction away from the central axis of the rotating rollers; two baffles, mounted on the mobile trolley, located at both ends of the rotating rollers; and a linkage gear for transmission. The drive unit connects to the rotating rollers, enabling the two rollers to rotate in opposite directions. This opposite rotation causes the scrapers on the rollers to periodically contact the floor of the toilet body and scrape away water stains in the same direction. It also causes the two scrapers to abut against each other, lifting the water stains off the floor. A water collection channel is located inside the rotating rollers along their axial direction. Several water collection holes are located on the outer wall of the rollers and connect to the water collection channel. A negative pressure source is used to provide negative pressure into the water collection channel to absorb water stains.

[0010] Furthermore, at least six mounting slots are provided on a single roller.

[0011] Furthermore, the toilet also includes a rubber strip located at the end of the scraper.

[0012] Furthermore, an arc surface is provided on the rubber strip.

[0013] Furthermore, the linkage gear includes: a first gear and a second gear that are meshed together, the first gear being mounted on one of the rotating rollers and the second gear being mounted on the other rotating roller; the toilet also includes: a rack that is arranged along the movement path of the moving trolley and is meshed with the first gear.

[0014] Furthermore, a vacuum pump is selected as the negative pressure source. The vacuum pump is connected to the water collection channel through a pipe fitting, and the pipe fitting is rotatably installed in the water collection channel through a dynamic sealing component.

[0015] The beneficial effects of this invention are as follows: By using this invention, a scraper driven by a moving trolley can scrape away residual water stains on the floor of the toilet, which can promptly clean urine stains on the floor of the toilet, effectively inhibiting the growth of bacteria, and eliminating the need for cleaning personnel, thus reducing labor costs; a spray assembly is also provided to spray disinfectant liquid on the floor of the toilet, disinfecting the floor and improving the cleanliness of the toilet; a sterilization lamp is also provided to provide ultraviolet irradiation to the floor for further disinfection.

[0023] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0024] Example 1

[0025] Reference Figure 1 As shown, this embodiment of the invention provides a self-cleaning toilet, comprising: a mobile trolley 2, movably installed inside the toilet body 1; a driving component for driving the mobile trolley 2 to reciprocate along a fixed path inside the toilet body 1; a spray assembly 3, installed on the mobile trolley 2, for spraying cleaning liquid onto the floor of the toilet body 1; a scraper 4, installed on the mobile trolley 2, for scraping away water stains on the floor of the toilet body 1; a sterilization lamp 5, installed on the mobile trolley 2, for providing ultraviolet irradiation to the floor of the toilet body 1; and a water storage tank, disposed inside the toilet body 1, for receiving water stains scraped away by the scraper 4.

[0026] Reference Figure 2 and Figure 3As shown, the toilet also includes: a guide rail 21, which is set on the toilet body 1, and a movable trolley 2 is movably installed on the guide rail 21; a water tank 11, which is opened on the ground of the toilet body 1 along the length of the scraper 4 and is connected to a water storage tank for receiving water stains; a cover plate 12, which is hinged to the toilet body 1 for sealing the water tank 11; a rotary motor 13; a first connecting rod 14, which is hinged to the cover plate 12; and a second connecting rod 15, which is hinged to the first connecting rod 14 at one end and to the output shaft of the rotary motor 13 at the other end. The output shaft of the rotary motor 13 rotates forward / reverse, which can drive the cover plate 12 to rotate around the hinge shaft 16, thereby opening / closing the water tank 11.

[0027] Specifically, the scraper 4 is set along the width of the toilet body 1 in the length direction, and the moving trolley 2 moves in a straight line back and forth along the length of the toilet body 1.

[0028] In practical use, when no one is using the toilet, the drive unit is activated, which drives the moving trolley 2 to move along the length of the toilet body 1, causing the scraper 4 to move along the direction close to the water tank 11, thereby scraping water stains and debris on the scraper 4's movement path into the water tank 11. Of course, during the movement of the scraper 4 close to the water tank 11, the spray assembly 3 is also in operation, spraying cleaning liquid onto the floor of the toilet body 1 to improve the cleanliness of the floor of the toilet body 1 by the scraper 4. Of course, during the movement of the scraper 4 close to the water tank 11, the sterilization lamp 5 is also activated, using ultraviolet light to disinfect the floor of the toilet body 1.

[0029] After the cleaning action is completed, the drive component drives the mobile trolley 2 to reset. During this movement, the spray assembly 3 stops operating. The sterilization lamp 5 is in working condition, and performs secondary irradiation disinfection on the floor of the toilet body 1, which to a certain extent achieves the purpose of drying the floor and improves the user's toilet satisfaction.

[0030] By using this invention, when no one is using the toilet, the mobile cart 2 can drive the scraper 4 to scrape away residual water stains on the floor of the toilet body 1, effectively cleaning urine stains on the floor of the toilet body 1 and inhibiting bacterial growth. Furthermore, it eliminates the need for cleaning personnel for the toilet body 1, reducing labor costs. A spray assembly 3 is also provided to spray disinfectant liquid onto the floor of the toilet body 1, disinfecting the floor and improving its cleanliness. Finally, a sterilization lamp 5 is provided to provide ultraviolet radiation to the floor for further disinfection.

[0031] It is understood that the spray assembly 3 includes: a water pump (not shown in the figure), a liquid storage tank (not shown in the figure), and a water pipe 9. The water pump is connected to the liquid storage tank, and the water pipe 9 is set on the mobile trolley 2 along the width direction of the toilet body 1. Of course, several spray nozzles are opened on the water pipe 9, and the start and stop of the spraying of disinfectant liquid by the start and stop of the water pump can be controlled.

[0032] It is easy to know that the storage tank is used to store disinfectant liquid, and pasteurized disinfectant liquid can be selected.

[0033] It is understandable that a stepper motor is used as the driving component. It is common knowledge in the field that the stepper motor drives the moving trolley 2 along the guide rail 21, so it will not be described in detail here.

[0034] In this embodiment, an infrared sensor is used to detect whether there are humans inside the toilet body 1.

[0035] In this embodiment, a control terminal (which may be a CPU controller) is also provided on the toilet body 1. The control terminal is electrically connected to electronic components such as stepper motors, infrared sensors, and water pumps. A suitable programming language is set in the control terminal to transmit control signals, thereby realizing the automatic operation of cleaning work.

[0036] Example 2

[0037] In embodiment 1, water stains on the ground are scraped off by scraper 4. The water stains on the ground need to be pushed from one side to the other along the length of the toilet body 1, which prolongs the movement path of urine stains on the ground. In addition, by setting a cover plate 12 on the ground to cover the water tank 11, the cover plate 12 needs to be tilted at a fixed angle to open the water tank 11 during the cleaning action. As a result, the surface of the cover plate 12 cannot be cleaned by scraper 4, resulting in cleaning dead corners on the ground of the toilet body 1.

[0038] Reference Figure 4 , Figure 5 and Figure 6As shown, compared with Embodiment 1, in this embodiment, the toilet further includes: at least two rotating rollers 6, parallel to the ground of the toilet body 1, both rotatably mounted on the mobile trolley 2; several mounting grooves 61, arranged in an array along the circumferential direction of the rotating rollers 6, the depth direction of the mounting grooves 61 extending along the radial direction of the rotating rollers 6, and several scrapers 4 slidably mounted in the grooves; a spring 62, disposed between the scrapers 4 and the rotating rollers 6, for providing the scrapers 4 with a tendency to move in a direction away from the central axis of the rotating rollers 6; two baffles 63, mounted on the mobile trolley, located at both ends of the rotating rollers 6; and a linkage. Gears are used to drive the drive components and the rotating rollers 6, enabling the two rotating rollers 6 to rotate in opposite directions. The opposite rotation of the two rotating rollers 6 can cause the scrapers 4 on the two rotating rollers 6 to periodically contact the ground of the toilet body 1 and scrape away water stains in the same direction. It can also cause the two scrapers 4 to abut against each other and lift the water stains off the ground. A water collection channel 64 is opened inside the rotating roller 6 along the axial direction of the rotating roller 6. Several water collection holes 65 are opened on the outer wall of the rotating roller 6 and connect to the water collection channel 64. A negative pressure source is used to provide negative pressure into the water collection channel 64 to absorb water stains.

[0039] Specifically, take two scrapers 4 symmetrically installed on two rotating rollers 6 as an example.

[0040] When the trolley 2 moves along the guide rail 21, it can drive the two rotating rollers 6 to rotate through the linkage gear, and the two rotating rollers 6 rotate in opposite directions.

[0041] During the rotation of the rotating roller 6, it can drive the two scrapers 4 symmetrically arranged on the two rotating rollers 6 to contact the ground; the sides of the two scrapers 4 and the sides of the baffle 63 can form a U-shaped groove, which intercepts water stains on the ground in the U-shaped groove.

[0042] The rotating roller 6 continues to rotate, and the two scrapers 4 move closer to each other until the two scrapers 4 come into contact, scraping away the water stains at the bottom of the U-shaped groove.

[0043] The rotating roller 6 continues to rotate, and the two abutting scrapers 4 move upward in sync, moving away from the ground, lifting the water stains between the two scrapers 4 off the ground.

[0044] The rotating roller 6 continues to rotate until the two abutting scrapers 4 are parallel to the horizontal plane, at which point the scrapers 4 can be tilted at a fixed angle; under the action of gravity, the water stains are guided to flow toward the rotating roller 6.

[0045] The water flowing towards the rotating roller 6 is drawn away by the negative pressure source through the water collection hole 65.

[0046] In this invention, the floor of the toilet body 1 is divided into several U-shaped grooves along its length. Two rotating rollers 6 rotate, which drives two symmetrically arranged scrapers 4 to scrape and clean the water stains at the bottom of the U-shaped grooves. This effectively shortens the distance that the water stains are pushed on the ground by the scrapers 4, reduces the time that urine stains in the water stains slide on the ground, helps to reduce the growth of bacteria, and can clean up urine stains in time, reducing odor.

[0047] In this invention, water stains are sucked away by the negative pressure source through the water collection hole 65, eliminating the need to install a cover plate 12 on the floor of the toilet body 1. The floor of the toilet body 1 is a whole, eliminating cleaning dead corners on the floor and improving the user's toilet experience.

[0048] Furthermore, at least six mounting grooves 61 are provided on a single rotating roller 6, and several U-shaped grooves are alternately formed by several symmetrically arranged scrapers 4.

[0049] Furthermore, the toilet also includes a rubber strip 66, which is located at the end of the scraper 4. The rubber strip 66 is in contact with the ground with an interference fit, which improves the cleanliness of the scraper 4 in removing water stains from the ground.

[0050] Furthermore, an arc surface is provided on the rubber strip 66 to improve the smoothness of contact between the scraper 4 and the surface of the ground / moving trolley 2 and prevent jamming.

[0051] Specifically, the linkage gear includes: a first gear and a second gear that are meshed together, the first gear being mounted on one of the rotating rollers 6 and the second gear being mounted on the other rotating roller 6; the toilet also includes: a rack 7, which is arranged along the movement path of the moving trolley 2 and is meshed with the first gear.

[0052] It is easy to see that when the trolley 2 moves, the first gear is driven to rotate by the fixedly installed rack 7, which in turn drives the second gear to rotate, causing the two rollers 6 to rotate in opposite directions.

[0053] Specifically, a vacuum pump is selected as the negative pressure source. The vacuum pump is connected to the water collection channel 64 through the pipe fitting 8, and the pipe fitting 8 is rotatably installed in the water collection channel 64 through the dynamic sealing component 81. The vacuum pump can provide negative pressure to the water collection channel 64 to suck away water stains.

[0054] It is readily apparent that the dynamic sealing component 81 can employ existing dynamic sealing technologies such as oil seals and labyrinth seals, which will not be elaborated upon here.

[0055] Those skilled in the art will understand that although preferred embodiments of the invention have been described, those skilled in the art, upon learning the basic inventive concept, can make other changes and modifications to these embodiments. Therefore, the appended claims are intended to be interpreted as including both the preferred embodiments and all changes and modifications falling within the scope of the invention. Clearly, those skilled in the art can make various alterations and modifications to the invention without departing from its spirit and scope. Thus, if these modifications and modifications of the invention fall within the scope of the machine equivalents of the claims, the invention also intends to include these modifications and modifications.
