[0031] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0032] Example 1
[0033] like Figures 1-5 As shown, an overflow structure for a urinal includes a urinal body 1 and an overflow section 2. The overflow section 2 includes an overflow hole 3, a water seal, and a drain channel 5. The overflow hole 3 is provided on the inner wall of the urinal bowl 7 of the urinal body 1. The overflow hole 3 is located on the back and side of the inner wall of the urinal bowl 7. In this embodiment, it is preferable that there are three overflow holes 3. The overflow holes 3 are lower than the highest water level of the urinal bowl 7. The overflow holes 3 are connected to one end of the water seal, and the other end of the water seal is connected to the drain channel 5. The water seal can store a certain amount of water to prevent sewer odors from entering the toilet through the overflow holes 3.
[0034] The overflow section 2 also includes a water inlet 6, one end of which is connected to a clean water source, and the other end is connected to a water seal. This allows some of the clean water to flow into the water seal when the urinal is flushed, which can replace the water in the water seal and prevent the water in the water seal from becoming smelly and emitting odors.
[0035] The water seal is the first water trap 4, which is an inverted S-shaped pipe or a pipe longitudinally symmetrical to an inverted S-shape. This facilitates the storage of sufficient water in the first water trap 4, ensuring a stable water seal. It should be noted that "inverted S-shaped" means a shape similar to an S-shape rotated 90°. The overflow hole 3 is located at the upper part of the first water trap 4. The upper end of the first water trap 4 is connected to the inlet channel 6, and the lower end of the first water trap 4 is connected to the drain channel 5.
[0036] The cross-sectional dimension of the water flow channel at one end of the first water trap 4, which connects to the water inlet channel 6, is larger than that of the subsequent channel, resulting in a larger water storage volume. This is beneficial for storing more water and for storing water more effectively and stably within the water seal.
[0037] An overflow section 2 is disposed on the outer wall of the urinal body 1, and the overflow section 2 is integrally formed with the urinal body 1. The cross-sections of the drain channel 5 and the inlet channel 6 are semi-circular, and the cross-section perpendicular to the water flow direction within the water seal is also semi-circular. The cross-section of the water flow channel is semi-circular. In other embodiments, the cross-sections of the drain channel 5 and the inlet channel 6, and the cross-section perpendicular to the water flow direction within the water seal, may also be other shapes, such as circular.
[0038] In other embodiments, the overflow section 2 is a separate structure attached to the outer wall of the urinal body 1.
[0039] A water-retaining edge 15 is provided on the side of the toilet bowl 7 away from the wall. The water-retaining edge 15 can prevent urine from splashing onto the user when using the toilet. The overflow hole 3 is lower than the top of the water-retaining edge 15.
[0040] Urinals usually have a screen cover at the drain outlet to prevent waste from flowing into the sewer.
[0041] The implementation principle of this embodiment is as follows: When using the urinal normally, after flushing, some clean water flows into the first trap 4 through the inlet 6, and then the water is discharged into the sewer through the drain 5. This replaces the water in the first trap 4 and prevents the water in the first trap 4 from becoming smelly and emitting odors. When the drain outlet 12 of the toilet bowl 7 is blocked, 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 sewage level reaches the overflow hole 3, the sewage is discharged through the overflow hole 3, flows through the first trap 4 and the drain 5 to the sewer, and prevents sewage from overflowing outside the toilet bowl 7 and polluting the bathroom environment.
[0042] Example 2
[0043] like Figures 6-8 As shown, the difference between this embodiment and Embodiment 1 is that the water seal is a U-shaped second water trap 18, the overflow section 2 also includes an overflow channel 8, the overflow hole 3 is set at the overflow channel 8, the overflow hole 3 is connected to one end of the second water trap 18 through the overflow channel 8, one end of the second water trap 18 is also connected to the inlet channel 6, and the other end of the second water trap 18 is connected to the drain channel 5; the overflow channel 8, the second water trap 18 and the drain channel 5 are arranged horizontally in sequence and connected, and the connection between the overflow channel 8 and the second water trap 18 is also connected to the lower end of the inlet channel 6; the drain channel 5 is an upward-curving inclined V-shaped pipe, the highest point a of the bottom wall of the overflow channel 8 is higher than the highest point b of the bottom wall of the drain channel 5, the highest water level of the second water trap 18 is lower than the highest point a of the bottom wall of the overflow channel 8, and the highest water level of the second water trap 18 is lower than the highest point b of the bottom wall of the drain channel 5.
[0044] The overflow channel includes a lower overflow section 19 and an upper overflow section 20. The lower overflow section 19 is connected to the upper overflow section 20. An overflow hole 3 is located at the lower overflow section 19 and is connected to the overflow hole 3. The upper overflow section 20 is connected to the inlet channel 6 and the second water trap 18. The highest point of the bottom wall of the overflow channel is located at the upper overflow section 20.
[0045] The implementation principle of this embodiment is as follows: When using the urinal normally, after flushing, some clean water flows into the second trap 18 through the inlet 6, and then the water is discharged from the drain 5 or overflow hole 3 into the sewer. This replaces the water in the second trap 18, preventing the water in the first trap 4 from becoming smelly and emitting odors. In this embodiment, the overflow hole 3 is not directly located at the water seal, and the water replacement effect within the water seal is better than in the first embodiment. When the drain outlet 12 of the toilet bowl 7 is blocked, the sewage in the toilet bowl 7 cannot be discharged from the drain outlet 12, and the sewage in the toilet bowl 7 accumulates more and more. When the sewage level is higher than the drain outlet 12, the sewage will eventually overflow. When the highest point b of the bottom wall of waterway 5 is reached, the sewage level is high and the pressure is high. The highest point a of the bottom wall of overflow channel 8 is higher than the highest point b of the bottom wall of drainage channel 5. Due to the siphon effect, the water stored in the second trap 18 is pushed to the drainage channel 5. There is a water pressure difference between the second trap 18 and the overflow channel 8. Sewage is continuously discharged through the overflow hole 3, flowing through the overflow channel 8, the second trap 18 and the drainage channel 5 to reach the sewer. The highest water level of sewage can only reach the highest point b of the bottom wall of drainage channel 5, preventing sewage from overflowing outside the toilet bowl 7 and polluting the bathroom environment.
[0046] Example 3
[0047] like Figures 1-8 As shown, a urinal adopts the overflow structure of the urinal in Embodiment 1 or Embodiment 2. The upper part of the urinal body 1 is provided with a water inlet 9, and the water inlet channel 6 is connected to a clean water source through the water inlet 9. The upper part of the urinal bowl 7 is provided with a brushing hole 10, which is connected to the water inlet 9. The bottom of the urinal bowl 7 is provided with a sewage discharge section 11, which includes a drain outlet 12, a third water trap 13 and a sewage outlet 14 connected in sequence. The drain outlet 12 is located at the bottom of the inner wall of the urinal bowl 7. The drainage channel 5 of the overflow section 2 is connected to the sewage outlet 14, and the sewage outlet 14 is connected to the sewer.
[0048] More specifically, the water inlet 9 includes a buffer water zone 16 and a water inlet 17. The water inlet 17 is connected to a clean water source and is connected to the buffer water zone 16. The scrubbing holes 10 are located at the bottom of the buffer water zone 16. Multiple scrubbing holes 10 are arranged in the same horizontal line. The buffer water zone 16 is connected to the scrubbing holes 10 and the water inlet channel 6.
[0049] The present invention has been further described above with reference to specific embodiments. However, it should be understood that the specific description herein should not be construed as limiting the substance and scope of the present invention. Various modifications made by those skilled in the art to the above embodiments after reading this specification are all within the scope of protection of the present invention.
