Description

Technical Field

[0001] The utility model relates to a drain, in particular to an anti-odor drain which can be opened and closed automatically. Background Art

[0002] A drain is a drainage device used for drainage, and is commonly used on washbasins. The drain is directly installed in the drainage hole under the washbasin. At this time, the limit part on the upper end of the drain is pressed on the inner wall of the lower side of the basin, and the limit nut screwed on the drain is pressed on the outer wall of the lower side of the basin to fix the drain. The traditional drain uses a flap to open and close the basin. When the flap blocks the upper port of the drain, the water in the basin will be trapped in the basin. When the flap is flipped sideways, the upper port of the drain opens, and the water in the basin will flow into the drain through the upper port of the drain, and then be discharged into the sewer through the pipe connected to the lower end of the drain, completing the drainage work.

[0003] During actual use, the water in the basin needs to be stored. Therefore, in order to facilitate water use and realize automatic drainage of the basin, most of the time, the flap is in a flipped state and the upper port of the drain is in an open state. However, since the lower end of the drain is connected to the sewer through a pipe, when the upper end of the drain is in an open state for a long time, the odor of the sewer can easily flow up into the basin through the drain, eventually causing the indoor air to be polluted by the odor. Summary of the invention

[0004] The utility model aims to solve the existing technical problem and provide an anti-odor drain that can be opened and closed automatically. The utility model can automatically determine whether it is in a drainage state and can automatically control the connection state between the lower end of the drain and the sewer, so that when the drain is not draining, the lower end is in a closed state, effectively preventing the odor in the sewer from rising up and causing air pollution, thereby achieving an anti-odor effect.

Therefore, the odor from the sewer needs to break through the two seals when it rises to the basin, which effectively prevents the odor from rising. If the sealing sleeve does not seal well due to the weakened elasticity of the return spring, the float sealed by gravity can always ensure its own seal and prevent the odor from rising, thereby avoiding the odor from rising to the basin and causing air pollution to the greatest extent, and effectively achieving an odor-proof effect.

[0020] A first threaded hole 27 is provided at the center of the upper surface of the opening and closing plate 10, and the lower end of the lifting rod 8 is screwed into the first threaded hole 27; a plurality of second threaded holes 28 corresponding to the position of the guide rod 15 are provided at the outer edge of the upper surface of the opening and closing plate 10, and the lower end of the guide rod 15 is screwed into the second threaded hole 28.

[0021] An annular sealing groove 29 is provided on the inner walls of the upper and lower ends of the guide hole 14 and the inner walls of the upper and lower ends of the lifting hole 7; a sealing ring 30 matching with the sealing groove 29 is provided in the sealing groove 29.

[0022] The conical hole 17 is provided with a floating ball 31 which fits with the inner wall thereof; the position where the outer wall of the floating ball 31 fits with the inner wall of the conical hole 17 is higher than the position of the water outlet hole 18 .

[0023] A limit cover 32 is screwed to the upper end of the conical hole 17 , and a plurality of water holes 33 are provided on the upper surface of the limit cover 32 and communicate with the inner space thereof; a floating distance 34 is provided between the upper inner wall of the limit cover 32 and the upper end of the float 31 .

[0024] A regular hexagonal disassembly hole 35 is provided at the center of the upper surface of the limiting cover 32 .

[0025] The method of using the utility model is as follows:

[0026] When it is necessary to open the drain, the flip cover 5 can be pressed downward. The flip cover 5 is round. Once the flip cover 5 is flipped sideways, the flip cover 5 will no longer block and seal the upper end port of the upper shell 1. At this time, the water in the basin can flow into the upper shell 1 through the upper end port of the upper shell 1. The water flow entering the upper shell 1 will be divided into two parts. One part of the water flow directly impacts the upper surface of the limiting cover 32 and the upper surface of the guide portion 16, and the other part enters the tapered hole 17 through the water through hole 33 on the limiting cover 32. As the subsequent water flow continues to enter the tapered hole 17, the water level in the tapered hole 17 will continue to rise. At this time, the float 31 floats up, and the outer wall of the float 31 no longer fits the inner wall of the tapered hole 17. At this time, the water flow in the tapered hole 17 flows to the water outlet 18 through the gap between the outer wall of the float 31 and the inner wall of the tapered hole 17, and finally flows out from the water outlet 18 to the outside of the cone 9, and then the water flows downward to the opening and closing hole 13. When the upper surface of the limit cover 32 and the upper surface of the guide part 16 are impacted by the water flow, the conical member 9 moves downward under the pressure of the water flow. When the conical member 9 moves downward, the return spring 12 is compressed and generates elasticity, and the opening and closing plate 10 moves downward synchronously. When the opening and closing plate 10 moves downward, the opening and closing plate 10 will drive the sealing sleeve 20 to move downward synchronously. As the sealing sleeve 20 moves downward, the sealing cone surface 21 of the outer wall of the sealing sleeve 20 no longer blocks and seals the lower end opening of the opening and closing hole 13, and the lower end opening of the opening and closing hole 13 is in an open state. At this time, the water flow flowing from the upper end opening of the opening and closing hole 13 into the opening and closing hole 13 can flow through the lower end opening of the opening and closing hole 13 to the space between the lower surface of the opening and closing seat 6 and the upper surface of the opening and closing plate 10, and then flow to the lower end port of the lower shell 2 through the water gap 11 between the outer peripheral surface of the opening and closing plate 10 and the inner wall of the lower shell 2, and then discharge into the sewer through the pipe connected to the lower shell 2 to complete the drainage work.

[0027] As the water discharge ends, the float 31 will automatically fall under the action of gravity, and the outer wall of the float 31 will fit with the inner wall of the tapered hole 17 again to form a seal, which is equivalent to directly blocking the water outlet 18. At the same time, without the opposition of water pressure, the conical member 9 will move up and reset under the elastic action of the reset spring 12, so that the opening and closing plate 10 drives the sealing sleeve 20 to move up and reset, so that the sealing cone surface 21 of the sealing sleeve 20 will block and seal the lower end of the opening and closing hole 13 again to form a first seal. Therefore, the odor from the sewer needs to break through the two seals to effectively avoid the odor from rising. If the reset spring 12 is weakened due to elasticity, resulting in poor sealing of the sealing sleeve 20, the float 31 sealed by gravity can always ensure its own seal, prevent the odor from rising, and avoid the odor from rising to the basin to cause air pollution to the greatest extent, effectively playing a deodorizing effect.

[0028] A number of evenly distributed guide holes 14 are provided on the opening and closing seat 6, and a number of guide rods 15 matching the guide holes 14 are provided on the outer edge of the upper surface of the opening and closing plate 10. The upper ends of the guide rods 15 pass upward out of the guide holes 14. The existence of the guide rods 15 can play a guiding role when the opening and closing plate 10 drives the sealing sleeve 20 to move up and down, thereby ensuring that the sealing sleeve 20 can accurately open and close the lower end opening of the opening and closing hole 13.

[0029] A screw hole 23 is provided in the center of the upper end surface of the positioning rod 19, and a positioning plate 24 is provided on the upper end surface of the positioning rod 19 to fit therewith. The diameter of the positioning plate 24 is larger than the diameter of the positioning rod 19, and the outer edge of the lower surface of the positioning plate 24 fits with the upper end surface of the sealing sleeve 20. A through hole 25 that penetrates the screw hole 23 is provided in the center of the positioning plate 24. A positioning screw 26 passes downward through the through hole 25 and is screwed into the screw hole 23. The lower surface of the head of the positioning screw 26 fits with the upper surface of the positioning plate 24. This fixing method can not only ensure the stability of the sealing sleeve 20 when it is sleeved on the outside of the positioning rod 19, but also facilitates the disassembly and assembly of the sealing sleeve 20, and facilitates the replacement of the sealing sleeve 20.

[0030] A first threaded hole 27 is provided at the center of the upper surface of the opening and closing plate 10, and the lower end of the lifting rod 8 is screwed into the first threaded hole 27. This fixing method is conducive to the disassembly and assembly of the lifting rod 8, and is convenient for the replacement of the lifting rod 8 and other components.

[0031] The outer edge of the upper surface of the opening and closing plate 10 is provided with a plurality of second threaded holes 28 corresponding to the positions of the guide rods 15 , and the lower ends of the guide rods 15 are screwed into the second threaded holes 28 . This fixing method is conducive to the disassembly and assembly of the guide rods 15 , and is convenient for the replacement of the guide rods 15 .

[0032] The inner walls of the upper and lower ends of the guide hole 14 and the inner walls of the upper and lower ends of the lifting hole 7 are both provided with an annular sealing groove 29, and a matching sealing ring 30 is provided in the sealing groove 29. The presence of the sealing ring 30 can effectively ensure the sealing between the inner wall of the guide hole 14 and the outer wall of the guide rod 15, and between the inner wall of the lifting hole 7 and the outer wall of the lifting rod 8.

[0033] There is a floating distance 34 between the upper inner wall of the limiting cover 32 and the upper end of the floating ball 31 . The floating distance 34 can effectively ensure that the floating ball 31 has a sufficient floating stroke, thereby ensuring the normal opening of the water outlet 18 .

[0034] A regular hexagonal disassembly hole 35 is provided at the center of the upper surface of the limit cover 32 . The limit cover 32 can be easily rotated by simply inserting one end of the hexagonal wrench into the disassembly hole 35 , thereby realizing quick disassembly and assembly of the limit cover 32 .
