Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0030] Next, in conjunction with the attached Figure 1 to the attached Figure 8 and specific embodiments, the present utility model will be described in detail:

[0031] Embodiment 1

[0032] Refer to Figure 1 、 4Based on the existing toilet structure, the toilet is composed of an upper ring blank 13 and a main body blank 9. The main body blank 9 includes a toilet pot 15, a water tank and a sewage pipe. The water inlet waterway of the water tank is connected to the toilet pot, and the outlet of the sewage pipe is connected to the inlet of the toilet sewer. The inner wall of the toilet pot 15 is provided with an overflow hole 1, the outlet of the water inlet waterway 16 of the water tank is connected to the outside of the overflow hole 1 and the overflow hole 1 is located inside the outlet, and the bottom of the water inlet waterway 16 is provided with a water outlet hole 2 with a diameter of about 18 mm, and the water outlet hole 2 is located below the overflow hole 1. The inlet end of the secondary waterway 3 is connected to the water outlet hole 2, and the outlet end of the secondary waterway is connected to the sewer outlet.

[0033] When the toilet drain outlet is blocked, the sewage flows back into the water tank inlet waterway 16 through the overflow hole 1, and will not overflow the toilet. Finally, the sewage enters the secondary waterway 3 from the pre-set outlet hole 2, flows through the secondary waterway 3 and merges into the bathroom sewer.

[0034] Furthermore, considering that the amount of sewage entering at one time is too large and may backflow into the water inlet channel 16 of the entire water tank, a partition 4 is provided on the bottom surface of the water inlet channel 16. The partition 4 is used to block sewage containing solid impurities. A first overflow space 5 is formed between the partition 4 and the outer wall of the pot 15, and the water outlet 2 is located at the bottom of the first overflow space 5.

[0035] Furthermore, three water inlet holes 17 with a diameter of about 5 mm are opened on the partition, and the angle of the water inlet holes 17 is inclined downward by 5 to 15 degrees, so that a small amount of water can enter the first overflow space 5 when the water inlet waterway 16 is flushed, and the debris in the first overflow space 5 is discharged from the toilet. The water inlet holes 17 are slightly inclined downward, ensuring the downward impact of the water while preventing the water flow from rushing to the overflow hole 1.

[0036] The secondary water channel 3 can be a conventional plastic pipe, the inlet end of which is directly connected to the water outlet 2, and the other end can be connected to the inlet of the sewer.

[0037] Example 2

[0038] refer to Figures 2 to 7 The plastic pipe is exposed outside the toilet, which is not beautiful and has a short life and needs to be replaced frequently. Example 2 improves the internal structure of the large body and changes the plastic pipe into a built-in pipe, which is integrated with the entire toilet and is beautiful and practical.

[0039] Furthermore, the outer wall of the pot 15 is provided with a second overflow space 6, the second overflow space 12 is located at the lower end of the pot, the height of the second overflow space 6 is lower than the first overflow space 5, the outer wall of the second overflow space 6 is provided with a sewage port 7, the outlet end of the secondary waterway is connected to the sewage port 7, and the second overflow space 6 is provided with an inlet of a built-in pipe 10 directly connected to the sewer pipe. The sewage in the first overflow space 8 flows into the second overflow space 12 through the height difference.

[0040] Further, referring to Figure 3 , the overflow channel adhesive plate 8 is in an arc structure, and the overflow channel adhesive plate 8 and the outer wall of the main body blank 9 enclose to form a secondary channel.

[0041] Further, the bottom of the first overflow space 5 is connected to the second overflow space 6 by adhesively bonding the overflow channel adhesive plate 8.

[0042] Further, a slope is provided on the lower bonding surface of the overflow channel adhesive plate 8 to direct the water in the space to the second overflow space 6, and the slope is 5-20°.

[0043] In order to cooperate with the integrated design of the secondary channel, in this embodiment, a built-in pipeline 10 can be provided in the main body blank 9. The built-in pipeline 10 is an L-shaped pipeline. The vertical part is hidden in the base of the main body blank 9, and the horizontal part is hidden in the bottom plate of the base. The built-in pipeline 10 leads directly to the inlet of the sewer. The second overflow space 6 is provided with an inlet leading directly to the built-in pipeline 10, and the sewage in the second overflow space 12 flows into the inlet of the sewer through the built-in pipeline 10.

[0044] Further, referring to Figure 8 , a water bay 11 is provided at the part where the built-in pipeline 10 extends into the inlet of the sewer pipeline. The water bay 11 is in a U-shaped pipe structure, and the depth of the water bay is ≥51 mm, ensuring the isolation between the sewer and the toilet bowl and preventing the odor in the sewer from entering the room through the overflow pipeline.

[0045] Further, the lower part of the first overflow space 5 is provided as an inclined surface 12. The inclined surface 12 is provided with a slope to direct the water in the space to the water outlet hole 2. The water outlet hole 2 is provided at the lowest position of the inclined surface, and the slope is 5-15°.

[0046] In the main body blank 9, it is not limited to be set as a pipeline, and it can also be set as a cavity. The cavity is divided into two parts. One part is hidden in the base of the main body blank 9, and the other part is horizontally hidden in the bottom plate of the base.

[0047] For a toilet bowl with a clogging prevention structure according to the present utility model, its working process is as follows: If the sewage outlet is clogged, the water level in the toilet bowl will gradually rise. When the water level rises to a certain height, the water will enter the overflow system through the overflow holes provided on the inner wall of the pot. The overflow system works, and the water entering the overflow holes first enters the first overflow space, which is formed between the partition plate and the outer wall of the pot. The water will flow into the water outlet holes provided at the bottom of the water inlet channel. The water from the water outlet holes then enters the secondary channel. The secondary channel is formed by the enclosure of the overflow channel adhesive plate and the outer wall of the main body blank. Its inlet end is communicated with the water outlet hole, and the outlet end is connected to the sewer outlet or the sewage outlet.

[0048] The sewage flows in the secondary channel and finally is discharged into the sewer through the built-in pipeline (if any) or directly through the sewage outlet.

[0049] The utility model relates to a toilet with a clogging prevention structure, and its advantages are as follows: effectively solving the problem of sewage overflow when the traditional toilet is clogged during sewage discharge. In Embodiment 1, by adding an overflow hole, a water outlet hole and a secondary water channel system, the safe guidance and discharge of sewage are realized. At the same time, the partition design in the water tank effectively blocks the backflow of dirt, ensuring the cleanliness and safety of the water tank. On this basis, Embodiment 2 is further optimized by changing the secondary water channel to a built-in type, which not only improves the overall aesthetic degree, but also enhances the durability and reduces the maintenance cost. Its unique second overflow space and built-in pipeline design make the sewage discharge smoother and more efficient. At the same time, the built-in U-shaped water bend effectively isolates the sewer odor, ensuring the freshness of the indoor air.

[0050] The above further describes the present utility model with the aid of specific embodiments. However, it should be understood that the specific description here should not be construed as a limitation on the essence and scope of the present utility model. Various modifications made by those of ordinary skill in the art to the above embodiments after reading this specification all fall within the scope protected by the present utility model.
