The water outlet hose is connected to the outlet of the water supply pump, and the suction inlet pipe is connected to the inlet of the suction pump. A water source is connected to the inlet of the water supply pump. The water supply pump and the suction pump operate automatically and simultaneously so as to wash the bottom of the pet water-washing toilet when a motion sensor detects that the pet has exited the pet water-washing toilet.

Description

[Technical Field]

[0001] FIELD OF THE DISCLOSURE The present disclosure relates to pet toilets, and more particularly to automatic pet toilets using a pressurized flush discharge system. [Background technology]

[0002] Automatic pet flushing toilets are known. They are particularly useful in urban areas where owners have difficulty finding suitable outdoor areas for their pets to defecate. Ideally, the pet's waste is discharged into a municipal sewer system. U.S. Patent Publication No. 8,434,426 discloses an automatic pet toilet with a recessed bowl and a central drain hole. Flushing and draining are gravity-driven. The recessed bowl has a grate, which is undesirable because it is difficult to clean and can retain particulate matter. U.S. Patent Publication No. 2017 / 0245459 discloses an automatic pet toilet with a recessed bowl and a central drain hole. This automatic pet toilet also flushes and drains by gravity. The recessed bowl is somewhat slippery, which can cause pets to step into the central drain hole, which is undesirable. U.S. Patent Publication No. 2015 / 0053140 discloses a device for cleaning a pet toilet. The pet toilet uses a mesh grate in the bowl. Urine passes through the mesh grid into the container. Feces remains on the mesh and is removed by hand. The container is flushed with a water pump but drains by gravity. Gravity flushing and draining is not very effective at removing feces from the bowl, grid, or mesh. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] U.S. Patent Publication No. 8,434,426 [Patent Document 2] U.S. Patent Publication No. 2017 / 0245459 [Patent Document 3] U.S. Patent Publication No. 2015 / 0053140 Summary of the Invention

[0004] The pet flush toilet of the present disclosure has a bottom, right and left sides, a front end, and a rear end, and includes a bowl with a drain opening at the rear end near the bottom, a water outlet opening at the right or left side above the bottom, and a pet inlet opening at the front end. A water outlet hose is inserted at one end into the water outlet opening, and a suction inlet pipe is inserted at one end into the drain opening. A water pump and a suction pump for the pet flush toilet each have an inlet and an outlet. A second end of the suction inlet pipe is connected to the inlet of the suction pump, and a water source is connected to the inlet of the water pump. The water pump and the suction pump are configured to operate simultaneously to flush the bottom of the pet flush toilet. The pet flush toilet has a base with a water tank, a motion detector, and a support stand with an electrical control module. The water source is a water tank with a water outlet valve, and the water tank receives water from a water supply hose connected to a water faucet. The electrical control module includes a timer, a switch, and circuitry that operate the motion sensor, the water pump, and the suction pump. The electrical control module operates the water pump and the suction pump for a predetermined period of time when the pet enters the bowl and then exits the bowl. The outlet pipe is connected to the outlet of the suction pump, and the outlet pipe is configured to connect to a sewer pipe.

[0005] An advantage of the pet flush toilet of the present disclosure is the automatic flushing system, which uses a water pump to flush the toilet bottom at a desired pressure and simultaneously suction the toilet bottom for a desired period of time.

[0006] An additional advantage is the motion detection system that automatically flushes and vacuums within seconds after your pet exits the pet toilet.

[0007] A further advantage is the suction system that allows the pet toilet to be discharged into the sewer.

[0008] An added advantage is that the pet toilet is easy to build, maintain and durable.

[0009] A further advantage is a pet toilet with adjustable pressure, suction and flush duration.

[0010] A further advantage is that the toilet bowl is positioned substantially flat on the floor, making it natural for pets to use and walk up to the pet toilet. [Brief explanation of the drawings]

[0012] Although the following description sets forth in detail preferred embodiments of the invention, it is understood that the invention may be embodied in other embodiments and may be practiced in various ways, and that the invention is not limited in its application to the precise illustrative arrangements of parts and method steps illustrated in the accompanying drawings.

[0013] FIG. 1 is a front perspective view of a pet flush toilet 10 according to an exemplary embodiment of the present disclosure. The pet flush toilet 10 has a bowl 11 having a bottom 12, a right side 13A, a left side 13B, a front end 13C, and a rear end 13D. The front end 13C of the bowl 11 has an entrance opening 14 for a pet (e.g., a dog) to enter the bowl 11. The bowl 11 rests on a base 15. A water tank or reservoir 16 is placed at the rear end 13D of the bowl 11. The reservoir 16 has a top cover 17. The reservoir 16 is held by a support stand 23. A motion sensor 18 is attached to the support stand 23. One end of a water outlet hose 19 is attached to the left side 13B of the bowl 11 and extends into a water outlet opening 20 in a central region of the left side 13B. A water outlet hose 19 may also be attached to the right side 13A. A discharge opening 21 is located at the rear end 13D of the bowl 11 near the bottom 12 of the bowl 11. The discharge opening 21 is connected to a suction / exhaust discharge pipe 22.

[0014] FIG. 2 is a left-side perspective view of the pet water closet 10. FIG. 2 also shows the suction pump 24 and the water pump 25. An inlet hose 26 is attached to the inlet of the water pump 25. An outlet hose 19 is attached to the outlet of the water pump 25 and extends to an outlet opening 20 on the left side 13B of the bowl 11. A water supply hose 29, connected to a faucet, supplies water to the pet water closet 10. An electrical control module 30 is attached to the support stand 23. Power is supplied to the electrical control module 30 through a power cord 31. The electrical control module 30 contains timers, switches, and circuitry that operate the motion sensor 18, the suction pump 24, and the water pump 25 in a manner well known in the art. Electrical wiring 33 connects the suction pump 24 and the water pump 25 to the electrical control module 30.

[0015] FIG. 3 is a rear perspective view of the pet water closet 10. FIG. 3 further shows the outlet pipe 28 of the suction pump 24. The suction exhaust pipe 22 is connected to the suction outlet pipe 28. FIG. 3 also shows the outlet valve 34 in the water tank 16, the water tank inlet hose 35 extending from the water supply hose 29 into the water tank 16, and the inlet hose 26 for the water pump 25 extending from the water tank 16 to the water supply pump 25. When water is supplied from the water tank 16 to the water supply pump 25 through the inlet hose 26, the outlet valve 34 opens to allow the water tank 16 to be refilled by the water supply hose 29. However, the water supply hose 29 may optionally be attached directly to the inlet of the water pump 25, bypassing the water tank 16. FIG. 4 is an enlarged rear perspective view of the suction pump 24 and the water supply pump 25 of the pet water closet 10.

[0016] During use, the pet flush toilet monitors movement within the bowl area using a motion detector. When a pet enters the bowl, the pet is detected by the motion detector. When the pet completes its excretion and exits the bowl, the pet's movement is again detected. Then, after a selected time, e.g., 5 to 10 seconds, the electronics in the electrical control module activate the water pump and suction pump for a selected time, e.g., 5 to 30 seconds. The water pump supplies water to the outlet hose at a desired pressure, and as the water enters the bowl, it spreads across the entire bottom of the bowl. The suction pump immediately sucks water from the bottom of the bowl through the suction opening and flushes it through the suction outlet pipe. This cooperative operation of the water pump and suction pump results in improved cleaning of the bottom of the bowl. The suction outlet pipe can be directed to the outdoors, a toilet, a sewer, or a sealed container. When these pumps are stopped by the electronics, the electronics reset for the next flush cycle.
