[0012] As a preferred embodiment, the cross-section of the pipe in the overflow portion perpendicular to the water flow direction is semicircular.

[0013] As a preferred embodiment, an isolation mesh cover is provided at the drain outlet.

[0014] As a preference, the lower end of the drainage channel of the overflow portion is connected to the side wall of the second water trap through a pipe.

[0015] As a preferred embodiment, the water outlet of the pipeline is located on the side wall of the second water trap, and the water outlet is close to the drain.

[0016] As a preferred embodiment, an overflow platform is arranged on the inner wall of the urinal body at a position corresponding to the overflow hole, the outer side of the overflow platform is a water-facing surface for guiding water to flow downward, and the overflow hole is arranged on the bottom surface of the overflow platform.

[0017] As a preference, the direction of the water flow channel inside the overflow platform connected to the overflow hole is obliquely upward, and the water flow channel connected to the overflow hole is connected to the first water trap.

[0018] The present invention has the following advantages:

[0019] (1) The present invention provides an overflow portion on the urinal body. When the drain outlet of the urinal is blocked, sewage accumulates in the toilet bowl and can be discharged from the overflow hole of the overflow portion, thereby preventing the sewage from overflowing outside the toilet bowl and polluting the toilet environment. The drainage channel of the overflow portion is connected to the sewage discharge portion. When the drain outlet is blocked, the flushing hole is blocked by a blocking device. When flushing, the clean water source only flows to the overflow portion, and the water flow of the overflow portion can backwash to clear the drain outlet of the sewage discharge portion.

[0020] (2) The urinal is equipped with a water level monitor and a blocking device. When the toilet bowl drain is blocked, water accumulates in the toilet bowl. When the water level monitor detects the accumulated water, it will send a signal to the control system. The control system controls the blocking device to block the brush hole and then controls the water inlet to start flushing. Because the brush hole has been blocked, the clean water source will no longer enter the toilet bowl from the brush hole. The clean water source only enters the overflow part and the backwash discharge part to dredge the drain, thereby realizing automatic dredging of the drain.

[0021] (3) The cross-sectional size of the pipeline is smaller than that of the drainage channel. When the drain outlet is blocked and backwash water is needed to unclog the drain outlet, the backwash water needs to have a larger thrust. The pipeline connecting the overflow part with the second water trap and the aperture diameter of the water outlet are smaller, so that the backwash water thrust is larger. The larger water thrust can push the garbage blocking the drain outlet, making the backwash water more effective.

[0022] (4) A water seal is formed in the first trap, which can prevent the odor from the sewer from entering the bathroom through the overflow hole.

[0023] (5) The overflow portion of the present invention is provided with a first water trap, which is connected to the water inlet, so that a portion of the clean water source can flow into the first water trap when the urinal is flushed, and the water in the first water trap can be replaced to prevent the water in the first water trap from becoming smelly and emitting odor.

[0024] (6) The overflow hole is arranged on the bottom surface of the overflow platform, so that the overflow hole is hidden and cannot be seen by the toilet user, making the urinal appearance more neat and beautiful; at the same time, urine is not easy to spill into the overflow hole when using the toilet.

DETAILED DESCRIPTION

[0039] The following will be combined with the accompanying drawings in the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work belong to the protection scope of the present invention.

[0040] Embodiment 1

[0041] like Figure 1-Figure 10 As shown, a urinal with anti-overflow comprises a urinal body 1 and an overflow part 2; a toilet bowl 7 is arranged in the urinal body 1, a water inlet 9 is arranged on the upper part of the urinal body 1, a brush hole 10 is arranged above the toilet bowl 7, and the brush hole 10 is connected with the water inlet 9; a sewage discharge part 11 is arranged at the bottom of the toilet bowl 7, and the sewage discharge part 11 comprises a water outlet 12, a second water trap 13 and a sewage outlet 14 which are connected in sequence, the water outlet 12 is arranged at the bottom of the inner wall of the toilet bowl 7, and the sewage outlet 14 is connected with the sewer; the overflow part 2 comprises an overflow hole 3, a first water trap 4, a water inlet 6 and a drainage channel 5, the inner wall of the toilet bowl 7 is provided with an overflow hole 3, and the overflow hole 3 is arranged on the back and side of the inner wall of the toilet bowl 7. In this embodiment, the number of overflow holes 3 is preferably There are three overflow holes 3, which are lower than the highest water level of the urinal 7. The overflow hole 3 is connected to the first water trap 4, and the overflow hole 3 is arranged at the upper part of the first water trap 4. One end of the water inlet 6 is connected to the clean water source through the water inlet part 9, and the other end of the water inlet 6 is connected to the upper end of the first water trap 4, so that a part of the clean water source can flow into the first water trap 4 when the urinal is flushed, and the water in the first water trap 4 can be replaced to prevent the water in the first water trap 4 from becoming smelly and emitting peculiar smell; the lower end of the first water trap 4 is connected to the upper end of the drain channel 5; the lower end of the drain channel 5 is connected to the second water trap 13; a water seal can be formed in the first water trap 4 to prevent the odor of the sewer from entering the toilet through the overflow hole 3. The urinal also includes a blocking device 19. When the drain outlet 12 is blocked, the blocking device 19 can block the flushing hole 10 during flushing, and clean water flows through the water inlet 6, the first water trap 4, the drainage channel 5, and the second water trap 13 in sequence to backwash and clear the drain outlet 12.

[0042] The overflow part 2 is arranged on the outer wall of the urinal body 1, and the overflow part 2 is arranged integrally with the urinal body 1. In other embodiments, the overflow part 2 can also be separately installed on the back and side of the urinal body 1, and the arrangement of the overflow part 2 is various and flexible.

[0043] The first water trap 4 is an inverted S-shaped pipeline or a longitudinally symmetrical pipeline with the inverted S shape, which is conducive to storing sufficient water in the first water trap 4 to stably form a water seal. It should be noted that "inverted S shape" means a shape similar to an S shape rotated 90 degrees.

[0044] The cross-sectional size of a water flow channel at one end of the first water trap 4 connected to the water inlet 6 is larger than that of the rear channel, and the water storage volume is relatively larger, which is conducive to storing more water and forming a water seal more effectively and stably.

[0045] The first water trap 4, the water inlet 6, and the upper section of the drain 5 are all arranged on the back or side of the urinal body 1, and the lower section of the drain 5 is arranged on the bottom surface of the urinal body 1. The upper section and the lower section of the drain 5 are connected by a turning channel to make the water flow change direction smoothly.

[0046] The pipe cross-sectional dimension of the lower portion of the drain channel 5 of the overflow portion 2 is smaller than that of the upper portion, and the lower end of the drain channel 5 is communicated with the side wall of the first trap 4 .

[0047] The lower end of the drain channel 5 of the overflow part 2 is connected to the side wall of the second water trap 13 through a pipe 24, and the pipe cross-sectional size of the pipe 24 is smaller than the pipe cross-sectional size of the drain channel 5. The water outlet 25 of the pipe 24 is located on the side wall of the second water trap 13, and the water outlet 25 is close to the drain 12. Urinals usually have an isolation mesh cover at the drain 12 to prevent garbage from flowing into the drain. When the drain 12 is blocked and needs to be cleared with backwash water, a larger thrust of the backwash water is required. The pipe 24 and the water outlet 25 connecting the overflow part 2 and the second water trap 13 have smaller aperture diameters, so that the thrust of the backwash water is greater, and there is a greater water thrust to push the garbage blocked in the drain 12, so that the effect of the backwash water is better.

[0048] The cross section of the pipe in the overflow portion 2 perpendicular to the water flow direction is semicircular. In other embodiments, the cross sections of the drain channel 5 and the water inlet channel 6, and the cross section of the first trap 4 perpendicular to the water flow direction may also be other shapes, such as circular.

[0049] The urinal also includes a control system and a water level monitor 18. The water inlet 9 includes a buffer water area 16 and a water inlet 17. The water inlet 17 is connected to a clean water source, and the water inlet 17 is connected to the buffer water area 16. The scrubbing hole 10 is located at the bottom of the buffer water area 16. A plurality of scrubbing holes 10 are arranged in the same horizontal line. The buffer water area 16 is connected to the scrubbing holes 10, and the buffer water area 16 is connected to the water inlet 6. The control system is electrically connected to the water level monitor 18 and the blocking device 19 respectively, and the control system includes an electric wire plug that can be connected to an external power supply (not shown in the figure); the water level monitor 18 is arranged in the toilet bowl 7, and the monitoring position of the water level monitor 18 is not higher than the overflow hole 3. The blocking device 19 is arranged in the buffer water area 16; when the water level monitor 18 detects accumulated water, the control system controls the blocking device 19 to block the scrubbing hole 10 and controls the clean water source to enter the overflow part 2 to backwash the second water trap 13 to dredge the drain 12.

[0050] The blocking device 19 includes a waterproof electric telescopic push rod 20 and a blocking plate 21. The body of the electric telescopic push rod is fixedly installed on the bottom surface of the buffer water area 16. The electric telescopic push rod 20 is electrically connected to the control system. The push rod end of the electric telescopic push rod 20 is fixedly connected to the blocking plate 21. When the push rod of the electric telescopic push rod 20 is extended, the blocking plate 21 blocks the top of the brush hole 10. When the urinal is in normal use, the push rod of the electric telescopic push rod 20 is retracted, and the brush hole 10 is unblocked.

[0051] The urinal further comprises an infrared sensor 22. The control system is electrically connected to the infrared sensor 22. The infrared sensor 22 is mounted on the upper part of the urinal body 1, and the infrared sensor 22 faces the toilet user.

[0052] The urinal further comprises a reminder device 23 , which is electrically connected to the control system. When the drain outlet 12 is blocked for a long time, the control system controls the reminder device 23 to give a sound reminder.

[0053] When the urinal is in normal use, when the infrared sensor 22 senses that the user is in front of the urinal, the control system does not trigger the flushing signal. When the user leaves, the infrared rays of the infrared sensor 22 are not blocked, and the corresponding signal is transmitted to the control system. The control system controls the opening of the water inlet 17 for flushing. The clean water source flushes the inner wall of the toilet bowl through the brush hole 10 and then flows into the drain port 12. A part of the clean water source flows into the first water trap 4 through the water inlet 6, and the water is then discharged from the drain 5 to the sewer, which can replace the water in the first water trap 4 to prevent the water in the first water trap 4 from becoming smelly and emitting odor.

[0054] When the drain outlet 12 of the toilet bowl 7 is blocked, sewage continuously flows into the toilet bowl 7, and the sewage in the toilet bowl 7 cannot be discharged from the drain outlet 12. The sewage in the toilet bowl 7 accumulates more and more. When the water level reaches the overflow hole 3, the sewage is discharged through the overflow hole 3, and the sewage flows into the second water trap 13 through the first water trap 4 and the drain 5, and then flows into the sewer through the second water trap 13 and the sewage outlet 14, so as to prevent the sewage from overflowing the outside of the toilet bowl 7 and polluting the bathroom environment. Sewage accumulates in the toilet bowl 7, and excess water flows out from the overflow hole 3. After the water level monitor 18 detects the accumulated water within a time range of 3s-5s, the corresponding signal is transmitted to the control system. After receiving the relevant signal, the control system controls the push rod of the electric telescopic push rod 20 of the blocking device 19 to push the blocking plate 21 to block the top of the brush hole 10, and then the control system triggers flushing again. The clean water source only flows to the overflow part 2. The clean water source rushes to the second water trap 13 and the drain outlet 12 through the drainage channel 5 of the overflow part 2, and flushes away the garbage blocking the drain outlet 12. After the garbage is broken up by the water flow, it flows into the drain outlet 12 again by gravity with the water flow and is discharged into the sewer. The water level monitor 18 detects no accumulated water, and the operation of reverse unblocking the drain outlet 12 is completed, and the urinal resumes normal use. The reverse dredging of the drain outlet 12 through the overflow part 2 can only be performed when the infrared sensor 22 detects that there is no one in front of the urinal to prevent sewage from splashing on people. When the overflow part 2 fails to reversely dredge the drain outlet 12 for multiple times (preferably three times), the water level monitor 18 always detects accumulated water, and the control system transmits the corresponding signal to the reminder device 23. After receiving the signal, the reminder device 23 emits a warning sound or light to remind the staff to manually clean and dredge it.

[0055] Embodiment 2

[0056] like Fig.11 , Fig.12 As shown, the difference between this embodiment and the first embodiment is that an overflow platform 8 is arranged at the position of the inner wall of the urinal body 1 corresponding to the overflow hole 3, the outer side of the overflow platform 8 is a water-facing surface for guiding water to flow downward, and the overflow hole 3 is arranged on the bottom surface of the overflow platform 8. The overflow hole 3 is hidden, and the user cannot see the overflow hole 3, making the urinal look neater and more beautiful.

[0057] The direction of the water flow channel connected to the overflow hole 3 inside the overflow platform 8 is obliquely upward, and the water flow channel connected to the overflow hole 3 is connected to the first water trap 4. When flushing, when the clean water source flows into the first water trap 4 from the water inlet 6, a part of the water flows into the oblique upward water flow channel connected through the overflow hole 3, flows through the overflow hole 3, and then flows into the toilet bowl, which can flush the overflow hole 3 and the oblique upward water flow channel connected to the overflow hole 3 inside the overflow platform.

[0058] The present invention is further described above with the aid of specific embodiments. However, it should be understood that the specific description here should not be construed as limiting the essence and scope of the present invention. Various modifications made to the above embodiments by ordinary technicians in the field after reading this specification are all within the scope of protection of the present invention.
