Description

Technical Field

[0001] The present invention relates to the field of home furnishing production technology, and in particular to a floor drain device for smart homes that prevents sewer odor from polluting indoor air. Background Art

[0002] The floor drain is an important interface connecting the drainage pipe system and the indoor floor. As an important component of the drainage system in a residence, its performance directly affects the quality of the indoor air and is very important for odor control in the bathroom. During the use of the existing general floor drain, the odor on the lower side will overflow after the sewage falls, causing odor in the bathroom. The existing anti-odor floor drain is generally equipped with many devices inside the floor drain to block the odor, resulting in a slow drainage speed. Therefore, a device is needed that can reduce the impact on the drainage speed while preventing the odor from overflowing. Therefore, it is very necessary to design a practical smart home floor drain device that can prevent sewer odor from polluting the indoor air. Summary of the Invention

[0003] The purpose of the present invention is to provide a floor drain device for smart home use that prevents sewer odor from polluting indoor air, so as to solve the problems raised in the above background technology.

[0004] In order to solve the above technical problems, the present invention provides the following technical solutions: a floor drain device for smart home use to prevent sewer odor from polluting indoor air, comprising a fixing ring, a cover hingedly connected to the upper portion of the fixing ring, a connecting tube fixedly connected to the lower surface of the fixing ring, and a drainage mechanism disposed inside the connecting tube;

[0005] The drainage mechanism includes an air cylinder, a first magnet, a second magnet, a connecting column, and a top plate. The rear side of the air cylinder is fixedly connected to the inner wall of the connecting cylinder, a first one-way valve is provided on the left part of the lower side of the air cylinder, and a second one-way valve is provided on the right side of the air cylinder. The input side of the first one-way valve is the upper side, and the input side of the second one-way valve is the lower side. The diameter of the first one-way valve is smaller than that of the second one-way valve. The inner wall of the air cylinder is slidably connected to the outer wall of the second magnet, the rear side of the first magnet is fixedly connected to the inner wall of the connecting cylinder, the upper side of the second magnet is fixedly connected to the lower end of the connecting column, the upper side of the connecting column passes through the first magnet and extends to the lower side of the first magnet and is fixedly connected to the lower side of the top plate, the outer wall of the first magnet is fixedly connected to the inner wall of the connecting cylinder, the upper side of the first magnet is connected to the lower side of the top plate through a spring, and the closing mechanism is arranged inside the top plate.

[0006] According to the above technical solution, the closing mechanism includes a movable plate, a spring piece, a third magnet, a fourth magnet, an elastic pull rope, an exhaust pipe, and an elastic film. A slide groove is provided inside the top plate, and the right side of the movable plate is inserted into the interior of the slide groove. The outer wall of the movable plate is slidably connected to the inner wall of the slide groove. The right side of the movable plate is connected to the right side of the inner wall of the slide groove through the spring piece. A fixed groove is provided inside the movable plate, and the outer wall of the third magnet is fixedly connected to the inner wall of the fixed groove. An empty groove is provided inside the connecting tube, and the upper right side of the empty groove is connected to the interior of the connecting tube. The inner wall of the empty groove is slidably connected to the outer wall of the fourth magnet, and the upper side of the fourth magnet is connected to the upper side of the inner wall of the empty groove through the elastic pull rope.

[0007] According to the above technical solution, the lower left side of the empty slot extends downward, and the lower side of the empty slot is connected to the middle part of the connecting tube through an exhaust pipe. The outer wall of the elastic film is fixedly connected to the inner wall of the connecting tube. An air cavity is formed between the outer wall of the elastic film and the inner wall of the connecting tube, and the right end of the exhaust pipe is located inside the air cavity.

[0008] According to the above technical solution, the right side of the fourth magnet and the left side of the third magnet are opposite magnetic poles.

[0009] According to the above technical solution, a tilting mechanism is provided on the left side of the movable plate, a convex structure is provided in the middle of the connecting cylinder, and the tilting structure contacts the lower side of the convex structure on the inner wall of the connecting cylinder.

[0010] According to the above technical solution, the lower side of the first magnet and the upper side of the second magnet are opposite magnetic poles.

[0011] According to the above technical solution, the magnetic attraction between the first magnet and the second magnet is greater than the total weight of the second magnet, the connecting column, the top plate, and the spring.

[0012] According to the above technical solution, the state of the spring where the third magnet and the fourth magnet are close to each other is in a stretched state.

[0013] Compared with the prior art, the present invention has the following beneficial effects: when in use, due to the hole-shaped structure provided on the cover, water can flow smoothly into the interior of the fixed ring; when the water flows onto the upper side of the top plate, the gravity exerted on the upper side of the top plate increases, which causes a greater downward pressure on the top plate, separating the first magnet from the second magnet, causing the top plate to descend, and allowing the water on the upper side of the top plate to flow out through the gap between the top plate, the outer wall of the movable plate, and the inner wall of the connecting tube, thereby achieving the purpose of the movable plate blocking odors on the lower side when not in use and allowing the water flow to descend when in use;

[0014] After the top plate drives the movable plate to descend, the elastic force of the spring sheet will cause the movable plate to retract into the inside of the top plate, so that the sum of the upper surfaces of the top plate and the spring sheet will be reduced, thereby reducing the resistance to the water flow. At the same time, since the side wall of the movable plate is a tilted structure, the water flow can descend smoothly, achieving the purpose of reducing the impact of the internal odor barrier device on the water flow during drainage;

[0015] After the drainage is completed, the pressure on the upper side of the top plate is reduced, and the top plate will rise due to the elastic force of the spring. At the same time, the second magnet will rise, causing the lower side of the second magnet to absorb air through the first one-way valve. Since the diameter of the first one-way valve is small, the resetting speed of the second magnet will be slowed down, and the speed at which the top plate is re-sealed will be slowed down, so that the water on the upper side of the top plate has enough time to be drained, so that the water will not accumulate inside the fixing ring and produce odor.

[0016] After the top plate is reset, the attraction between the third magnet and the fourth magnet will cause the fourth magnet to descend, and at the same time, the third magnet will pull the movable plate to move, so that the movable plate and the top plate will seal the inside of the connecting tube, thereby achieving the effect of eliminating odor. At the same time, the descent of the fourth magnet will cause the gas on its lower side to be discharged into between the elastic film and the inner wall of the connecting tube through the exhaust pipe, causing the elastic film to expand and seal the gap between the movable plate and the inner wall of the connecting tube, thereby enhancing the sealing effect and achieving the purpose of completely blocking odor.

[0025] The closing mechanism 407 includes a movable plate 701, a spring piece 702, a third magnet 703, a fourth magnet 704, an elastic pull rope 705, an exhaust pipe 706, and an elastic film 707. A sliding groove is provided inside the top plate 405. The right side of the movable plate 701 is plugged into the interior of the sliding groove. A tilting mechanism is provided on the left side of the movable plate 701. A protruding structure is provided in the middle of the connecting cylinder 2. The tilting structure contacts the lower side of the protruding structure on the inner wall of the connecting cylinder 2. The outer wall of the movable plate 701 is slidably connected to the inner wall of the sliding groove. The right side of the movable plate 701 is connected to the right side of the inner wall of the sliding groove through the spring piece 702. A fixed groove is provided inside the movable plate 701. The outer wall of the third magnet 703 is fixedly connected to the inner wall of the fixed groove. There is an empty slot, the upper right side of the empty slot is connected to the interior of the connecting tube 2, the inner wall of the empty slot is slidably connected to the outer wall of the fourth magnet 704, the right side of the fourth magnet 704 and the left side of the third magnet 703 are opposite magnetic poles, the state of the spring piece 702 near the third magnet 703 and the fourth magnet 704 is in a stretched state, the upper side of the fourth magnet 704 is connected to the upper side of the inner wall of the empty slot through an elastic pull rope 705, the lower left side of the empty slot extends downward, and the lower side of the empty slot is connected to the middle part of the connecting tube 2 through an exhaust pipe 706, the outer wall of the elastic film 707 is fixedly connected to the inner wall of the connecting tube 2, and an air cavity is formed between the outer wall of the elastic film 707 and the inner wall of the connecting tube 2, and the right end of the exhaust pipe 706 is located inside the air cavity.

[0026] When in use, the fixing ring 1 and the connecting tube 2 are fixed inside the preset sewer channel. Due to the hole-shaped structure provided on the sealing cover 3, the water flow can smoothly flow into the interior of the fixing ring 1. When the water flow converges on the upper side of the top plate 405, the gravity on the upper side of the top plate 405 increases, which will cause the top plate 405 to generate a large downward pressure, so that it drives the connecting column 404 to move vertically downward and the second magnet 403 to move downward in parallel. At the same time, the spring 406 is compressed. Since the rear side of the first magnet 402 is fixedly connected to the inner wall of the connecting tube 2, the downward movement of the second magnet 403 will separate the first magnet 402 from the second magnet 403. The top plate 405 is lowered, and the water on the top plate 405 is discharged through the gap between the top plate 405, the outer wall of the movable plate 701 and the inner wall of the connecting tube 2. When the top plate 405 moves downward, the elastic force of the spring 702 causes the movable plate 701 to be retracted into the interior of the top plate 405. At the same time, the gas under the second magnet 403 is discharged through the second one-way valve, so that the sum of the upper surface of the top plate 405 and the spring 702 is reduced, thereby reducing the resistance to the water flow. At the same time, since the side wall of the movable plate 701 is a tilting mechanism, the water flow can descend smoothly, achieving the goal of reducing the influence of the internal odor barrier device on the water flow during drainage. The purpose is that after the drainage is completed, due to the reduction of the pressure on the upper side of the top plate 405, the top plate 405 will rise due to the elastic force of the spring 406 and the suction force between the second magnet 403 and the first magnet 402. At the same time, due to the rise of the second magnet 403, the lower side of the second magnet 403 will be sucked through the first one-way valve. Since the diameter of the first one-way valve is small, the resetting speed of the second magnet 403 will be slowed down, and the speed at which the top plate 405 is re-reset and blocked will be slowed down, so that the water on the upper side of the top plate 405 has enough time to be emptied, so that the water flow will not be silted up inside the fixing ring 1 to produce odor. After 405 is reset, the magnetic attraction between the third magnet 703 and the fourth magnet 704 will cause the fourth magnet 704 to descend, and at the same time, the third magnet 703 will pull the movable plate 701 to move, so that the movable plate 701 and the top plate 405 will seal the inside of the connecting tube 2, thereby achieving the effect of eliminating odor. At the same time, the descent of the fourth magnet 704 will cause the gas on its lower side to be discharged into between the elastic film 707 and the inner wall of the connecting tube 2 through the exhaust pipe 706, so that the elastic film 707 will expand and seal the gap between the movable plate 701 and the inner wall of the connecting tube 2, so that the sealing effect is enhanced, thereby achieving the purpose of completely blocking the odor.
