Description

Technical Field

[0001] This utility model relates to the field of wastewater technology, specifically a wastewater odor prevention and purification device. Background Technology

[0002] Wastewater refers to water discharged from domestic and industrial sources that has been polluted to a certain extent. Water that has lost its original function is simply called wastewater. It mainly refers to water that has been used in daily life. From the perspective of wastewater source, wastewater can be defined as liquid or water carrying waste that is discharged from residential, government, commercial or industrial areas and mixed with groundwater, surface water, snowstorms, etc. Wastewater is classified into many categories, and correspondingly, there are many technologies and processes to reduce the impact of wastewater on the environment. According to the source of wastewater, wastewater can be divided into industrial wastewater, domestic sewage and commercial sewage. Domestic sewage includes kitchen sewage. Kitchen sewage is usually discharged into the sewer through the kitchen sink. The kitchen sink is connected to the sewer through the drain hose. Odors in the sewer can enter the sink through the drain hose, affecting the living environment of residents. Therefore, a wastewater odor prevention and purification device is needed to isolate the odor.

[0003] Existing domestic sewage odor prevention and purification devices generally install a U-shaped pipe between the water tank and the drain hose to isolate odors from the sewer. However, bacteria grow in the water inside the U-shaped pipe, producing odors. Since the U-shaped pipe is directly connected to the drain outlet of the water tank, the odors will enter the water tank through the U-shaped pipe. Furthermore, the structure of the U-shaped pipe makes it easy for debris to accumulate and is difficult to clean.

[0004] Therefore, those skilled in the art have provided a wastewater odor prevention and purification device to solve the problems mentioned in the background art. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1 to 8In this embodiment of the utility model, a sewage odor prevention and purification device includes a housing 1 installed between a kitchen sink drain and a drain hose. The housing 1 has a boss 2 and a connecting nut 3. The boss 2 has a fixing groove 4, and a sealing ring 5 is located within the fixing groove 4. The connecting nut 3 has a sealing groove 6, and a sealing ring 7 is located within the sealing groove 6. A water funnel 8 is located inside the housing 1. The housing 1 has no internal sealing components. The bottom of the water funnel 8 has a sealing component to isolate odors. The tubular housing 1 is fixedly connected between the kitchen sink drain and the drain hose, facilitating the discharge of sewage from the sink into the sewer. The boss 2 is integrally formed on the top of the housing 1. The connecting nut 3 is slidably connected to the outer wall of the housing 1. Screwing the connecting nut 3 to the kitchen sink drain allows for connection... Nut 3 abuts against boss 2, fixing housing 1 to the sink drain. Fixing groove 4 is opened on top of boss 2. Sealing ring 5 is snapped into fixing groove 4. After connecting nut 3 is screwed to the kitchen drain pipe, sealing ring 5 abuts against the kitchen sink drain, improving the sealing between the kitchen drain and housing 1. Sealing groove 6 is opened on the contact surface between connecting nut 3 and bottom of boss 2. Sealing ring 7 is fixedly installed in sealing groove 6. After connecting nut 3 is screwed to the kitchen sink drain pipe, sealing ring 7 abuts against bottom of boss 2, preventing water from leaking from the threads of connecting nut 3 to the outside of housing 1, further improving the sealing between housing 1 and kitchen sink drain. Drain hopper 8 is fixedly installed on the inner wall of housing 1, collecting water entering housing 1 and draining it downward through the bottom of drain hopper 8.

[0027] In one embodiment, the closure assembly includes a fixing plate 9 mounted on the inner wall of the housing 1. The fixing plate 9 is provided with a plurality of fixing seats 10. A flap 11 is hinged to the fixing seat 10. The fixing plate 9 is fixedly mounted on the inner wall of the housing 1 and located above the water funnel 8. The plurality of fixing seats 10 are circumferentially fixedly mounted at equal intervals on the bottom of the fixing plate 9. The flap 11 is respectively hinged to the plurality of fixing seats 10, so that the flap 11 can rotate a certain angle along the fixing seat 10, so that the plurality of flaps can be opened and closed.

[0028] A torsion spring 12 is provided between the flap 11 and the fixed base 10. The torsion spring 12 is fixedly installed at the hinge of the flap 11 and the fixed base 10. When water flows into the housing 1 from the kitchen sink, the flap 11 can flip downward under the pressure of the water flow to facilitate the discharge of kitchen sewage. When the sewage in the kitchen sink is drained, the torsion spring 12 can flip multiple flaps 11 upward, so that multiple flaps 11 can be flipped up and fit against the fixed plate 9, which can isolate the inside of the housing 1 when no water enters it and isolate the odor below the flap.

[0029] Based on the above embodiments, specifically, the sealing assembly includes multiple fixing blocks 13 installed on the drain hopper 8. Each fixing block 13 is provided with a water receiving tray 14. The multiple fixing blocks 13 are circumferentially and equidistantly fixed on the outer wall of the bottom of the drain hopper 8. The water receiving tray 14 is screwed onto the multiple fixing blocks 13 and can catch kitchen sewage leaking from the drain hopper 8. The water receiving tray 14 can be unscrewed from the fixing blocks 13 for easy cleaning.

[0030] Furthermore, the bottom of the drain hopper 8 is located inside the water receiving tray 14. When the kitchen sink drains, the sewage can enter the water receiving tray 14 through the drain hopper 8 and overflow from the top of the water receiving tray 14, facilitating sewage discharge. When the kitchen sewage is drained, a portion of water can be retained in the water receiving tray 14. The bottom of the drain hopper 8 can be located below the water surface in the water receiving tray 14, which can prevent the odor from the sewer from entering the drain hopper 8 through the top of the water receiving tray 14, further isolating the odor from the sewer.

[0031] In one embodiment, the sealing ring 7 is provided with a toothed ring 15, which is integrally formed on the top of the sealing ring 7. After the connecting nut 3 is screwed to the kitchen sink drain pipe, the toothed ring 15 can be held in place by the bottom of the boss 2. The toothed ring 15 can be squeezed and deformed, which can increase the contact area between the sealing ring 7 and the boss 2, thereby further improving the connection sealing between the housing 1 and the kitchen drain pipe.

[0032] Furthermore, the bottom of the housing 1 is provided with a mounting groove 16, and a waterproof rubber ring 17 is provided in the mounting groove 16. The waterproof rubber ring 17 is provided with a toothed ring 18. The mounting groove 16 is opened at the bottom of the housing 1, and the waterproof rubber ring 17 is fixedly installed inside the mounting groove 16, which can improve the sealing between the housing 1 and the sewer. The toothed ring 18 is integrally formed on the outer wall of the waterproof rubber ring 17 and tilts upward. After the sewer is inserted into the bottom of the housing 1, the toothed ring 18 can be squeezed and deformed by the drain hose, which can increase the contact area between the waterproof rubber ring and the drain hose, thereby improving the sealing between the housing 1 and the drain hose, increasing the friction between the waterproof rubber ring 17 and the drain hose, and preventing the drain hose from coming loose from the bottom of the housing 1.

[0033] During installation, place the connecting nut 3 onto the drain outlet of the sink. Rotate the connecting nut 3 to screw it into the drain outlet of the kitchen sink. As you continue to rotate the connecting nut 3, the sealing ring 5 abuts against the drain outlet, and simultaneously, the sealing ring 7 abuts against the bottom of the boss 2. When the connecting nut 3 is tightened, the housing 1 is fixed to the drain outlet of the sink. At the same time, the sealing ring 5 and the sealing ring 7 form a seal between the drain outlet and the housing 1. Then, insert the drain hose into the bottom of the housing 1, with the drain hose secured to the waterproof rubber ring 17. Under the action of the force, it is fixed, and a seal is formed between the drain hose and the housing 1. When the sink drains, kitchen sewage enters the interior of the housing 1 through the sink drain outlet. Then, the sewage splashes onto the top of the flap 11. Under the gravity of the sewage, the flap 11 is opened, and the sewage enters the interior of the drain hopper 8 and falls downwards. Then, the sewage enters the water receiving tray 14 from the bottom of the drain hopper 8. When the water level in the water receiving tray 14 rises to the top of the water receiving tray 14, the sewage flows from the top of the water receiving tray 14 to the bottom of the water receiving tray 14. The wastewater overflows from the outside and then enters the drain hose and flows into the sewer. When the kitchen wastewater in the sink is drained, the weight of the water remaining on the flap 11 is insufficient to push the flap 11 downwards. Under the action of the torsion spring 12, the flap 11 flips upwards, and multiple flaps 11 close together and adhere to the fixing plate 9. Since there is no subsequent addition of wastewater, some of the wastewater in the drip tray 14 remains in the drip tray 14. Because the bottom of the drain hopper 8 is located inside the drip tray 14, the bottom of the drain hopper 8 is located inside the drip tray 14. Below the water level, the area above and below the drain hopper 8 is isolated by the water in the water tray 14. The odor in the sewer is also isolated by the water in the water tray 14. After prolonged use, debris will accumulate in the water tray 14. The odor produced by the deterioration of the debris is isolated by the multiple flaps 11 that are gathered together. If it is necessary to clean the water tray 14, firstly, disconnect the drain hose from the bottom of the housing 1. Then, twist the water tray 14 to separate it from the fixing block 13. After that, remove the water tray 14 and clean it to remove dirt.

[0034] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
