Description

Technical Field

[0001] This invention relates to a toilet, specifically a toilet with a self-cleaning function. Background Technology

[0002] The toilet is composed of a toilet base and a toilet seat. The toilet seat includes a connecting seat, a cover plate, and a seat ring. The bottom of the connecting seat is fixedly connected to the rear of the toilet base, and the rear ends of the seat ring and the cover plate are movably hinged to the connecting seat.

[0003] Years of use have revealed that during toilet use, urine inevitably splashes onto the rim of the toilet base and / or the bottom of the seat. If not cleaned manually regularly, this not only produces unpleasant odors but also easily breeds bacteria and mold, posing a health risk. However, given the fast-paced lifestyle of modern people, manual cleaning requires a significant amount of time and is easily forgotten, creating substantial hygiene hazards and severely impacting the comfort of using the toilet. Summary of the Invention

[0004] To address the aforementioned problems, this invention designs a toilet with a self-cleaning function, which can perform self-cleaning operations on the edge of the toilet base and the bottom of the seat ring during flushing or separately, and features a simple structure and convenient cleaning.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A toilet with a self-cleaning function includes a toilet base and a toilet seat. The toilet seat is composed of a connecting seat, a cover plate, and a seat ring. The bottom of the connecting seat is fixedly connected to the rear of the toilet base. The rear ends of the seat ring and the cover plate are movably hinged to the connecting seat. The connecting seat has several water spray holes on both sides of its front end at the edge where it connects to the toilet base. The rear end of each water spray hole is connected to a water pump in the toilet tank via a water inlet pipe. The water pump is activated by a flush button on the water tank or a flush button on a smart toilet controller. Alternatively, the rear end of each water spray hole can be directly connected to a household cold water pipe via a water inlet pipe, and a control valve is installed in this water inlet pipe.

[0007] More specifically, the outer edge of the toilet base is provided with an anti-overflow protrusion.

[0008] More specifically, a water-guiding groove is provided on the rear side of the frontmost edge of the aforementioned toilet base.

[0009] More specifically, the bottom of the aforementioned seat ring is provided with several stop protrusions, which creates a gap between the bottom of the seat ring and the edge surface of the toilet seat to form a cleaning space.

[0010] More specifically, the aforementioned control valve is a manually operated angle valve.

[0011] More specifically, the aforementioned control valve is a normally closed solenoid valve, and the opening of the solenoid valve is controlled by the flush button on the toilet tank or the flush button on the smart toilet controller.

[0012] The toilet designed in this invention has several water spray holes on both sides of the front end of the toilet seat connecting seat. These holes can be used for simultaneous cleaning when flushing after using the toilet, thereby achieving self-cleaning of the toilet seat edge and / or the bottom of the seat ring. This can promptly flush away urine residue, prevent odors and the growth of harmful bacteria. The entire operation process is simple and quick, ensuring the cleanliness and hygiene of the toilet and improving the comfort of using the toilet. Attached Figure Description

[0015] Among them, 1—toilet base, 11—edge, 111—overflow prevention protrusion, 112—water guiding groove, 2—toilet seat, 21—connecting seat, 22—lid plate, 23—seat ring, 231—stop protrusion, 3—spray hole. Detailed Implementation

[0016] like Figure 1 and 2 As shown, a toilet with a self-cleaning function includes a toilet base 1 and a toilet seat 2. The toilet seat 2 is composed of a connecting seat 21, a cover plate 22 and a seat ring 23. The bottom of the connecting seat 21 is fixedly connected to the rear of the toilet base 1, which is used to install the cover plate 22 and the seat ring 23 on the toilet base 1. The rear ends of the seat ring 23 and the cover plate 22 are movably hinged to the connecting seat 21, and can be opened or closed as needed during use.

[0017] The front sides of the connecting seat 21 are provided with a number of water spray holes 3 at the connection points with the edge 11 of the toilet base 1. Each water spray hole 3 is arranged in a single row, double row or multiple rows. In this figure, only the single row structure is described. The function and technical effect of the double row or multiple row layout are the same, and will not be described again here.

[0018] Each of the above-mentioned spray nozzles 3 is connected to a water pump in the toilet tank via an inlet pipe. The water pump is activated by the flush button on the toilet tank or the flush button on the smart toilet controller. When the toilet is finished, pressing the flush button on the toilet tank, the flush button on the smart toilet, or the flush function button or cleaning button on the smart toilet mobile app will activate the water pump simultaneously with the toilet flush or activate it independently. The high-pressure water from each spray nozzle 3 washes the edge 11 of the toilet base and / or the bottom of the seat ring 23 to effectively remove urine stains. After cleaning, the water pump automatically shuts off after a certain period of operation via a delay or by pressing the corresponding function button.

[0019] In addition, the rear ends of each of the above-mentioned spray holes 3 can also be directly connected to the household cold water pipe through a water inlet pipe, and a control valve is installed in this water inlet pipe. This control valve can be a manually operated angle valve or a normally closed solenoid valve. When using an angle valve, after using the toilet, the angle valve is manually opened for cleaning, and after cleaning, the angle valve is manually closed. When set as a normally closed solenoid valve, after using the toilet, the solenoid valve is triggered to open by the flush button of the toilet tank, the flush button of the smart toilet controller, or the flush function button or cleaning button on the smart toilet mobile app, so as to achieve flushing or cleaning of the toilet base edge 11 and / or the bottom of the seat ring 23 simultaneously. After cleaning, the above-mentioned solenoid valve will automatically close after a certain period of operation or be closed by pressing the corresponding function button.

[0020] In summary, the spray hole 3 structure designed in this invention is suitable for both ordinary toilets and smart toilets. It can promptly flush away urine residue on the edge 11 of the toilet base and / or the bottom of the seat ring 23, effectively preventing odor generation and the growth of harmful bacteria. The entire cleaning process is simple and quick, ensuring the cleanliness and hygiene of the toilet and improving the comfort of using the toilet.

[0021] To prevent the washing water from the spray nozzles 3 from overflowing the toilet base edge 11 and staining the bathroom floor, an overflow-proof protrusion 111 is provided on the outer side of the toilet base 1 edge 11. This effectively prevents the washing water from overflowing, ensuring that all the wastewater from washing flows into the toilet base. Furthermore, considering that the washing water from the spray nozzles 3 on both sides converges at the front edge of the toilet base 1 edge 11, a water-guiding groove 112 is provided on the rear side of the front edge of the edge 11 to accelerate internal drainage.

[0022] Furthermore, to further improve the cleaning effect, the bottom of the seat ring 23 is provided with several stop protrusions 231, so that there is a gap between the bottom of the seat ring 23 and the edge surface of the toilet seat to form a cleaning water channel space, which can ensure smooth flow of cleaning water and make cleaning more thorough and cleaner.

[0023] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention in any way. Any simple modifications, equivalent changes, or alterations made to the above embodiments based on the technical principles of the present invention shall still fall within the scope of the technical solution of the present invention.
