Description

Technical Field

[0001] This utility model relates to the field of floor drain technology, and in particular to an odor-proof floor drain. Background Technology

[0002] In early building drainage systems, people simply drilled holes in the ground or used simple ceramic or stone pipe joints as drain outlets to discharge indoor sewage smoothly. These drain outlets had virtually no protection or odor prevention measures. Debris in the sewage could easily clog the drainage channels, and odors and insects from the sewers could easily enter the house through the drain outlets, causing many problems for people's living environment.

[0003] However, traditional floor drains are mostly simple in structure, relying solely on a simple cover to block the drain opening. While this can prevent large objects from falling into the drain pipe to some extent, it offers virtually no effective way to block or treat odors emanating from the sewer. Odorous gases such as hydrogen sulfide and ammonia can easily diffuse into the room through the drain opening, leading to poor indoor air quality and causing significant inconvenience to people's living and working environments, thus requiring improvement. Utility Model Content

[0004] The purpose of this utility model is to solve the technical problems mentioned in the background art.

[0005] This utility model adopts the following technical solution: an odor-proof floor drain, including a base, a fixing block installed at the top of the base, a rotating rod rotatably connected inside the fixing block, cover plates fixedly installed at both ends of the rotating rod, a placement groove opened at the top of the cover plate, a fine hole opened at the bottom of the cover plate, a sliding groove opened inside the placement groove, a movable cylinder sleeved inside the sliding groove, a spring fixedly installed at the rear end of the movable cylinder, a clamping block fixedly installed on the surface of the movable cylinder, an adsorption box placed against the surface of the clamping block, an adsorption box filled with activated carbon, a push block sleeved inside the sliding groove, a movable column fixedly installed at the top of the push block, a movable rod fixedly installed at one end of the movable column, a spring fixedly installed at one end of the movable rod, a fixing frame fixedly installed on the surface of the placement groove, a torsion spring sleeved inside the fixing frame, a rotating rod sleeved inside the torsion spring, and a closing plate fixedly installed on the surface of the rotating rod.

[0006] Preferably, the top of the fine hole is connected through the bottom of the placement groove, and the bottom of the adsorption box is fitted with the top of the fine hole. The torsion springs are in two sets and symmetrically distributed inside the fixing frame. This design, where the top of the fine hole is connected through the bottom of the placement groove and the bottom of the adsorption box is fitted with the top of the fine hole, allows odorous gases in the sewage to directly contact the activated carbon inside the adsorption box as they are emitted upwards through the fine hole. The activated carbon can effectively adsorb the odorous gases, maximizing its adsorption effect, improving the odor-proof effect, and ensuring that the odor from the sewage discharged from the floor drain diffuses as little as possible into the indoor environment, thus maintaining fresh indoor air.

[0007] Preferably, one end of the torsion spring is connected and fixed to the inner surface of the fixing frame, and the other end of the torsion spring is connected and fixed to the surface of the rotating rod. A groove is provided at the top of the cover plate, and one side of the groove is in contact with one side of the closing plate. Here, magnetic blocks are fixedly installed inside the placement groove and at the bottom of the closing plate, and they attract each other. When the closing plate is closed, the attraction between the magnetic blocks further enhances the tightness of the fit between the closing plate and the placement groove, improving the sealing performance of the placement groove and better preventing external dust, impurities, etc., from entering the placement groove and affecting the normal use of components such as the adsorption box. It also helps the torsion spring maintain the closed state of the closing plate to a certain extent, ensuring that the closing plate will not be accidentally opened due to slight vibrations or other factors during daily use. This improves the sealing and stability of the entire drain structure and ensures the normal functioning of all components within the placement groove.

[0008] Preferably, one side of the movable cylinder is semi-circular, one end of the first spring is connected and fixed to the surface of the movable cylinder, and the other end of the first spring is connected and fixed to the inner surface of the slide groove. The clamping block is L-shaped. Here, the L-shaped design allows the clamping block to clamp the adsorption box from the side, further enhancing the fixing effect on the adsorption box and ensuring its stable placement in the placement groove. This prevents shaking or tipping during use, ensuring the adsorption box continuously and stably performs its odor-preventing function and improving the stability and reliability of the entire drain structure.

[0009] Preferably, the push block is trapezoidal in shape, one end of the second spring is connected and fixed to the inner surface of the placement groove, and the other end of the second spring is connected and fixed to the surface of the moving rod. There are four sets of clamping blocks and springs, which are fitted against the four corners of the adsorption box. Here, the four sets of clamping blocks and springs, fitted against the four corners of the adsorption box, clamp and fix the adsorption box from four corners, making the fixation of the adsorption box in the placement groove more uniform and stable. This comprehensively prevents the adsorption box from shifting or shaking during use, ensuring that it can continuously and effectively perform its function of adsorbing odors.

[0010] Preferably, the push block, moving column, moving rod, and spring two are arranged in two sets and symmetrically distributed inside the placement groove and sliding groove. A push plate is fixedly installed at the other end of the moving rod. Magnetic blocks are fixedly installed inside the placement groove and at the bottom of the closing plate, attracting each other. Here, the magnetic blocks fixedly installed inside the placement groove and at the bottom of the closing plate attract each other. When the closing plate is closed, the attraction between the magnetic blocks further enhances the tightness of the fit between the closing plate and the placement groove, improving the sealing performance of the placement groove and better preventing external dust and impurities from entering the placement groove and affecting the normal use of components such as the adsorption box. It also assists the torsion spring one in maintaining the closed state of the closing plate to a certain extent, ensuring that the closing plate will not accidentally open due to slight vibrations or other factors during daily use. This improves the sealing and stability of the entire drain structure and ensures the normal functioning of all components within the placement groove.

[0011] Preferably, the base has a groove 1 on its surface, and a self-locking rebound device is fixedly installed inside the groove 1. The bottom end of the cover plate has a groove 2, and a fixing ball is fixedly installed inside the groove 2. A torsion spring 2 is sleeved inside the fixing block. Here, the bottom end of the cover plate has a groove 2, and the fixing ball is fixedly installed inside the groove 2. The fixing ball cooperates with the relevant structure on the base, playing a role in positioning, guiding, and auxiliary support during the opening and closing of the cover plate. This makes the opening and closing action of the cover plate more stable and smooth, reduces friction and wear between the cover plate and the base, extends the service life of the cover plate, and also ensures that the cover plate can accurately seal with the base when closed, improving the sealing performance of the drain and the stability of the overall structure.

[0012] Preferably, the self-locking rebound device is a small beetle-shaped rebound device. Two sets of self-locking rebound devices and fixed balls are symmetrically distributed inside the cover plate and base. One end of the second torsion spring is connected and fixed to the inner surface of the fixed block, and the other end of the second torsion spring is connected and fixed to the surface of the first rotating rod. Here, the self-locking rebound device is a small beetle-shaped rebound device. The small beetle-shaped rebound device has advantages such as compact structure, stable performance, moderate rebound force, and reliable self-locking. It can well adapt to the installation requirements of relatively small spaces like floor drains, and can stably achieve the automatic rebound and self-locking functions of the cover plate during long-term use, ensuring the reliability of the cover plate during opening and closing operations, reducing floor drain usage problems caused by rebound device failure, and improving the overall quality and user experience of the floor drain.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, by setting a base, fixing block, rotating rod, cover plate, placement groove, fine hole, sliding groove, moving cylinder, spring, clamping block, adsorption box, activated carbon, and push block structure, when the equipment is in use, the adsorption box and activated carbon structure can effectively block and adsorb odors emitted from the sewer, effectively prevent odor gases such as hydrogen sulfide and ammonia from spreading into the room through the drain outlet, prevent indoor air quality from deteriorating, avoid causing great trouble to people's living and working environment, and effectively improve the odor prevention effect of the equipment.

[0015] 2. In this utility model, by setting up a groove one, a self-locking rebound device, a groove two, a fixed ball, and a torsion spring two structures, when the equipment is in use, the multiple structures of the self-locking rebound device and the fixed ball make it easy for the staff to close and open the cover by stepping on it, effectively improving the convenience of the equipment, and at the same time effectively preventing odor.

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0027] Example 1

[0028] Please see Figures 1-7This utility model provides a technical solution: an odor-proof floor drain, including a base 1, a fixing block 2 installed at the top of the base 1, a rotating rod 3 rotatably connected inside the fixing block 2, and cover plates 4 fixedly installed at both ends of the rotating rod 3. A placement groove 5 is opened at the top of the cover plate 4, and a fine hole 6 is opened at the bottom of the cover plate 4. A sliding groove 7 is opened inside the placement groove 5, and a movable cylinder 8 is fitted inside the sliding groove 7. A spring 9 is fixedly installed at the rear end of the movable cylinder 8, a clamping block 10 is fixedly installed on the surface of the movable cylinder 8, and an adsorption box 11 is placed against the surface of the clamping block 10. The adsorption box 11 is filled with activated carbon 12. Inside the 7, a push block 13 is installed. A movable column 14 is fixedly installed on the top of the push block 13. A movable rod 15 is fixedly installed on the top of the movable column 14. A spring 16 is fixedly installed at one end of the movable rod 15. A fixed frame 17 is fixedly installed on the surface of the placement groove 5. A torsion spring 18 is installed inside the fixed frame 17. A rotating rod 19 is installed inside the torsion spring 18. A closing plate 20 is fixedly installed on the surface of the rotating rod 19. When the equipment is in use, the odor-proof floor drain is first installed at the drainage point. During normal use, the closing plate 20 on the rotating rod 19 is in a closed state under the action of the torsion spring 18, sealing the placement groove 5. When replacing the adsorption box 11, first, make contact with the surface of the closing plate 20, then pull the closing plate 20. The closing plate 20 rotates the rotating rod 19 by applying external pressure. Then, the rotation of the rotating rod 19 causes the torsion spring 18 to retract. Next, the movement of the closing plate 20 causes the magnetic block 23 to disengage. Then, press the moving rod 15. The moving rod 15 squeezes the spring 16 and moves the moving column 14. The movement of the moving column 14 moves the push block 13. The push block 13 squeezes the moving cylinder 8. Then, the movement of the moving cylinder 8 moves the clamping block 10. Then, the movement of the moving cylinder 8 causes the spring 9 to retract, causing the clamping block 10 to release its grip on the adsorption box 11. Then, take out the old adsorption box 11, put in the new adsorption box 11, and release the moving rod 15. The spring 9 and the components driven by the spring 9 return to their original positions. The spring 9 causes the clamping block 10 to re-clamp the new adsorption box 11, completing the replacement operation of the adsorption box 11.

[0029] Please see Figures 1-7The top of the fine hole 6 is connected to the bottom of the placement groove 5. The bottom of the adsorption box 11 is attached to the top of the fine hole 6. There are two sets of torsion springs 18, which are symmetrically distributed inside the fixing frame 17. One end of the torsion spring 18 is connected and fixed to the inner surface of the fixing frame 17, and the other end of the torsion spring 18 is connected and fixed to the surface of the rotating rod 19. The top of the cover plate 4 has a groove 21, one side of which is attached to one side of the closing plate 20. One side of the moving cylinder 8 is semi-circular. One end of the spring 9 is connected and fixed to the surface of the moving cylinder 8, and the other end of the spring 9 is connected and fixed to the inner surface of the sliding groove 7. The clamping block 10 is L-shaped, and the push block 13 is trapezoidal. One end of the spring 16 is connected and fixed to the inner surface of the placement groove 5, and the other end of the spring 16 is connected and fixed to the surface of the moving rod 15. There are four sets of clamping blocks 10 and springs 9, which are attached to the four corners of the adsorption box 11. The number of push block 13, moving column 14, moving rod 15 and spring 16 are two sets and are symmetrically distributed inside the placement groove 5 and the sliding groove 7. The other end of the moving rod 15 is fixedly installed with push plate 22. The inside of the placement groove 5 and the bottom of the closing plate 20 are both fixedly installed with magnetic blocks 23 and they attract each other. The self-locking rebound device 25 is a small beetle rebound device. The number of self-locking rebound device 25 and fixed ball 27 are two sets and are symmetrically distributed inside the cover plate 4 and the base 1. One end of torsion spring 28 is connected and fixed to the inner surface of fixed block 2, and the other end of torsion spring 28 is connected and fixed to the surface of rotating rod 3. The number of self-locking rebound device 25 and fixed ball 27 are two sets and are symmetrically distributed inside the cover plate 4 and the base 1. These symmetrically distributed components can make the cover plate 4 more evenly stressed during the opening and closing process, ensuring that the opening and closing action of the cover plate 4 is smooth and stable, and there will be no jamming or tilting caused by uneven force on one side.

[0030] Example 2

[0031] Please see Figures 1-3 The base 1 has a groove 24 on its surface, and a self-locking rebound device 25 is fixedly installed inside the groove 24. The bottom of the cover plate 4 has a groove 26, and a fixing ball 27 is fixedly installed inside the groove 26. A torsion spring 28 is sleeved inside the fixing block 2. When the cover plate 4 needs to be closed, the operator first applies pressure with their foot to rotate the cover plate 4. Then, the rotation of the cover plate 4 causes the torsion spring 28 to retract. Next, the rotation of the cover plate 4 causes the fixing ball 27 to move. Then, the cover plate 4 moves and comes into contact with the top surface of the base 1. Then, the fixing ball 27 moves and is fixed to the self-locking rebound device 25, thus closing the cover plate 4. When the cover plate 4 needs to be opened, the operator first presses the cover plate 4 with their foot. The self-locking rebound device and the resetting movement of the torsion spring 28 open the cover plate 4.

[0032] Working principle: When using the equipment, first install the odor-proof floor drain at the drainage point. During normal use, the closing plate 20 on the rotating rod 19 is in a closed state under the action of the torsion spring 18, sealing the placement groove 5. When replacing the adsorption box 11, first, contact the surface of the closing plate 20 with your hand, then pull the closing plate 20. The closing plate 20 drives the rotating rod 19 to rotate through external pressure. Then, the rotation of the rotating rod 19 drives the torsion spring 18 to retract. Next, the movement of the closing plate 20 causes the magnetic block 23 to disengage. Then, press the moving rod 15. The moving rod 15 squeezes the spring 16 and drives the moving column 14 to move. The movement of the moving column 14 drives the push block 13 to move. The push block 13 squeezes the moving cylinder 8. Then, the movement of the moving cylinder 8 drives the clamping block 10 to move. Then, the movement of the moving cylinder 8 drives the spring 9 to retract, causing the clamping block 10 to release its grip on the adsorption box 11. Then, take out the old adsorption box 11 and put in the new adsorption box 11. After 1, release the moving rod 15, and the spring 9 and the moving rod 15 and other components driven by the spring 9 will reset. The spring 9 will cause the clamping block 10 to clamp the new adsorption box 11 again, completing the replacement operation of the adsorption box 11. When it is necessary to close the cover plate 4, the operator first applies pressure with his foot to rotate the cover plate 4. Then, the rotation of the cover plate 4 will cause the torsion spring 28 to retract. Then, the rotation of the cover plate 4 will cause the fixed ball 27 to move. Then, the cover plate 4 will move and fit against the surface of the top of the base 1. Then, the fixed ball 27 will move and fix itself to the self-locking rebound device 25, thus closing the cover plate 4. When it is necessary to open, first press the cover plate 4 with your foot. The self-locking rebound device and the reset movement of the torsion spring 28 will open the cover plate 4.
