[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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 making creative efforts are within the scope of protection of the present invention.
[0027] Reference Figure 1 、 Figure 2 and Figure 3 , the utility model provides an embodiment: a sewer odor-proof and overflow-proof device, including a drainage pipe 4, a water tank 1 is installed on the top of the drainage pipe 4, and the water tank 1 is arranged to facilitate the storage of water, a mounting shell 5 is fixedly connected to the middle of the drainage pipe 4, and an odor-proof and overflow-proof component is arranged on the left side of the mounting shell 5. By arranging the odor-proof and overflow-proof component, the sewer pipe can be prevented from odor, a filter plate 11 is plugged into the mounting shell 5, and impurities in the waste water can be filtered by arranging the filter plate 11, and a disassembly component is arranged on the right side of the outside of the mounting shell 5, which is convenient for disassembly and cleaning of the filter plate 11, a drainage plate 6 is installed on the top of the drainage pipe 4, and the drainage plate 6 is convenient for storing and discharging the water inside the water tank 1, a faucet 2 is installed on the upper part of the water tank 1, and a control valve 3 is installed outside the faucet 2;
[0028] The anti-odor and anti-overflow component includes a mounting block 7, which is fixedly connected to the inner left side of the mounting shell 5. A rotating block 8 is rotatably connected to the inside of the mounting block 7, and a baffle 9 is fixedly connected to the bottom of the rotating block 8. A sealing gasket 10 is installed on the outer left side of the baffle 9. The baffle 9 is made of plastic, which is light and easily pushed by water flow, thereby achieving low-resistance switching operation. The sealing gasket 10 is made of rubber, which has good buffering properties and can reduce the impact noise of the baffle 9 when it is closed.
[0029] Specifically, when the drainage pipe 4 is draining, water flows through the drainage pipe 4 and pushes the sealing gasket 10, so that the sealing gasket 10 drives the external fixed baffle 9, which rotates along the inside of the mounting block 7 with the cooperation of the rotating block 8. The pressure of the water flow pushes the baffle 9 open, forming a smooth drainage channel, thereby achieving smooth drainage. In the process of wastewater discharge, the pluggable filter plate 11 installed inside the mounting shell 5 is used to effectively filter impurities in the wastewater. The filter plate 11 can capture and block large particles of impurities in the water flow, such as food residues, grease and hair, to prevent Prevent it from entering the pipe. When the drainage is completed, the water pressure is reduced, and the baffle 9 loses the driving effect of the water flow and naturally falls back under the action of gravity, driving the sealing gasket 10 to cover the outlet of the drainage pipe 4 again and restore the sealing state. The rubber material of the sealing gasket 10 provides good flexibility and sealing performance, and can completely fit the drain outlet, preventing odor and sewage backflow in the sewer, and at the same time blocking the possible path of pests, realizing the anti-odor and anti-overflow function of the sewer pipe. This design greatly improves the air quality of the kitchen environment and prevents the spread of sewer odor into the room.
[0030] Reference Figure 4 、 Figure 5 and Figure 6 The disassembly and assembly components include a U-shaped frame 13, which is fixedly connected to the right side of the outside of the mounting shell 5. Both sides of the U-shaped frame 13 are fixedly connected to fixed rods 16. The two fixed rods 16 are slidably connected to a horizontal plate 18. The right side of the horizontal plate 18 is fixedly connected to the mobile rod 14. The mobile rod 14 is fixedly connected to the handle 12. The left side of the horizontal plate 18 is fixedly connected to the insertion rod 19. The two fixed rods 16 are externally sleeved with a return spring 17. The mobile rod 14 is externally fixedly connected to a ring 15. By setting a circular The ring 15 is convenient for the operator to use, a second through hole 22 is opened inside the U-shaped frame 13, and the moving rod 14 is slidably connected to the inside of the second through hole 22. The second through hole 22 is provided to facilitate the movement of the moving rod 14, and a first through hole 20 is opened inside the mounting shell 5. The insertion rod 19 is slidably connected to the inside of the first through hole 20. The first through hole 20 is provided to facilitate the movement of the insertion rod 19. A card slot 21 is opened inside the filter plate 11, and the insertion rod 19 is plugged into the card slot 21, thereby improving the stability of the installation of the filter plate 11.
[0031] Specifically, when the filter plate 11 needs to be cleaned, first, by pulling the ring 15, the ring 15 drives the mobile rod 14 fixed on the outside to move, and the movement of the mobile rod 14 simultaneously pushes the horizontal plate 18 fixed on the outside to move parallel to the outside of the two fixed rods 16. During the movement of the horizontal plate 18, the plug 19 fixed on its left side applies pressure to the return spring 17 sleeved on the outside of the two fixed rods 16, causing the return spring 17 to gradually compress and deform, accumulating elastic potential energy. As the horizontal plate 18 continues to move, the plug 19 gradually disengages from the slot 21 in the mounting shell 5. After the plug 19 is completely disengaged from the slot 21, the fixed state of the filter plate 11 is released. At this time, the user can safely remove the filter plate 11 from the mounting shell 5 through the two handles 12. The filter plate 11 is designed to be easily removed from the inside to avoid damage to the equipment or spillage of residues. The design of the filter plate 11 is convenient for handheld cleaning. The user can remove food residues, grease, hair and other debris on the surface of the filter plate 11. After cleaning, the user reinserts the filter plate 11 into the interior of the mounting shell 5. At this time, it is only necessary to loosen the ring 15 and use the reaction force of the two reset springs 17 to automatically reset the cross plate 18 and the insertion rod 19. The insertion rod 19 is re-embedded into the interior of the card slot 21 to restore the filter plate 11 to a stable installation state, realizing quick disassembly and reset of the filter plate 11, so that the user can easily maintain and clean it, ensure that the filter plate 11 is always kept clean, effectively filter impurities, reduce the risk of impurity accumulation, keep the drainage pipe 4 smooth, and extend the service life of the device.
[0032] Working principle: When the drainage pipe 4 is draining, the water flows through the drainage pipe 4 to push the sealing gasket 10, and the sealing gasket 10 moves with the external fixed baffle 9 and rotates inside the mounting block 7 under the cooperation of the rotating block 8. The baffle 9 is pushed open by the water flow to complete the drainage operation. In the process of wastewater discharge, the filter plate 11 inserted in the mounting shell 5 is used to filter the impurities in the wastewater to avoid pipe blockage. When the drainage is completed, the baffle 9 loses the effect of the water flow and the sealing gasket 10 is used to cover the drainage pipe 4 under the action of gravity, thereby realizing the odor-proof and overflow-proof operation of the sewer pipe, preventing unpleasant odors from entering the room, and improving the air quality of the kitchen.
[0033] When the filter plate 11 needs to be cleaned, first, the ring 15 is pulled, and the ring 15 moves with the external fixed moving rod 14, and the moving rod 14 moves with the external fixed cross plate 18 to move outside the two fixed rods 16. When the cross plate 18 moves, the external left fixed plug rod 19 moves and squeezes the return springs 17 set on the outside of the two fixed rods 16, so that the two return springs 17 are deformed under the force. Then, when the plug rod 19 is disengaged from the inside of the card slot 21, the filter plate 11 can be taken out from the inside of the mounting shell 5 by the two handles 12 for cleaning. After cleaning, the filter plate 11 is inserted into the inside of the mounting shell 5. Then, after loosening the ring 15, the plug rod 19 is inserted into the inside of the card slot 21 under the reaction force of the two return springs 17, which makes it easy to disassemble and clean the filter plate 11, clean up the accumulated food residues, hair and other debris, prevent the drain pipe 4 from being blocked, and ensure smooth drainage.
