Description

Technical Field

[0001] The present application relates to the technical field of floor drains, and in particular to a novel self-sealing and odor-proof floor drain. Background Art

[0002] The floor drain is a crucial interface between the drainage piping system and the indoor floor. As a crucial component of a residential drainage system, its performance directly impacts indoor air quality and is crucial for controlling odors in the bathroom. Conventional floor drains are sealed in a variety of ways, with the water seal being the most common. After drainage, a certain amount of water is retained within the drain, preventing the escape of gases from the pipes below, thereby achieving a self-sealing and odor-resistant effect.

[0003] However, there are many problems with the current water-sealed floor drain, such as Figure 1 As shown, conventional floor drains store a certain amount of water through the presence of a water trap, so that the gas in the pipe cannot be dispersed. When there is water, the water overflows from the water trap and leaks. However, the size of the water trap is fixed, so the amount of stored water is fixed. The initial leakage amount during each leakage is not high, and the continuous leakage amount is relatively stable. After the floor drain has been used for a long time, dirt is easily attached to the water trap. Long-term accumulation will affect the use effect of the floor drain, make it easy to clog, produce odor, and require regular cleaning, which reduces the actual user experience. Utility Model Content

[0004] In order to solve the above-mentioned problems, improve the sealing and odor-proof function of the floor drain, and enhance the user experience, the present application provides a new self-sealing and odor-proof floor drain.

[0005] The present application provides a novel self-sealing and odor-proof floor drain adopts the following technical solution.

[0006] A novel self-sealing and odor-proof floor drain comprises a drain pipe and a drain bucket which is arranged at the bottom end of the drain pipe and is lifted and lowered by a lifting device;

[0007] The lifting device includes a floating mechanism and a limiting mechanism. The floating mechanism includes an elastic member arranged between the leakage pipe and the leakage bucket. The elastic member is used to provide elastic force for the leakage bucket to rise. The limiting mechanism is used to limit the descent of the leakage bucket.

[0008] The floating mechanism also includes a fixed block and a floating shaft. The fixed block is arranged on the leakage pipe, the floating shaft is arranged on the leakage bucket, the floating shaft passes through the fixed block in the up and down directions, and the elastic member is arranged on the floating shaft between the fixed block and the leakage bucket.

[0009] By adopting the above technical solution and setting up the lifting device, when there is a large amount of water in the leakage pipe and the water level rises, the water and the weight of the leakage bucket overcome the elastic force of the elastic member in the floating mechanism, causing it to descend, thereby achieving a large amount of water discharge, achieving a certain flushing effect. When the water volume decreases, the weight of the water and the leakage bucket cannot overcome the elastic force of the elastic member, and the leakage bucket is driven to rise until the water volume in the leakage pipe reaches a lower water level, at which point the limit mechanism limits the leakage bucket and prevents it from descending. The leakage pipe can then store a higher water volume. When the water level reaches a high water level, the limit mechanism loses its limit on the leakage bucket, and the water and the leakage bucket overcome the elastic force of the elastic member in the floating mechanism and descend, achieving drainage. By adopting the above technical solution, water storage can be achieved, a water seal can be achieved, and a self-sealing effect can be achieved to prevent gas from escaping from the pipe. The initial amount of drainage is large, which can achieve a certain flushing effect, making it difficult for dirt to adhere to the floor drain and downspout, reducing the possibility of dirt odor and clogging, achieving a certain cleaning effect, reducing the user's cleaning frequency, and improving the use effect.

[0010] Optionally, a top frame is provided on the top of the leaky bucket, the top end of the floating shaft is connected to the top frame, the fixed block is located at the bottom of the top frame, and the top and bottom ends of the elastic member are respectively against the top frame and the fixed block.

[0011] By adopting the above technical solution, the top and bottom ends of the elastic member are respectively against the top frame and the fixed block, and the elastic force of the elastic member can directly drive the top frame to move upward, thereby driving the leaking bucket to move upward.

[0012] Optionally, the limiting mechanism includes a swing rod, which is hinged to the leakage pipe and swings up and down. A floating block is provided at one end of the swing rod located inside the leakage pipe, and the end of the swing rod located outside the leakage pipe drives the limiting rod to move in the direction close to and away from the floating axis.

[0013] By adopting the above technical solution, through the setting of the floating block, it can float up and down with the change of the water level in the leakage pipe, and then drive the swing rod to swing, realizing the movement of the limit rod according to the change of the water level, thereby achieving the effect of limiting or releasing the limit of the floating shaft.

[0014] Optionally, a limit seat is provided on the leakage pipe at the top of the swing arm, a movable through hole is opened on the limit seat, the limit rod cooperates with the hole axis of the movable through hole, one end of the swing arm located outside the leakage pipe is hinged to one end of the intermediate connecting rod, and the other end of the intermediate connecting rod is hinged to the limit rod.

[0015] By adopting the above technical solution, the limit seat and the movable through hole opened on the limit seat can guide the limit rod, and the swing rod and the limit rod are hinged through the intermediate connecting rod to achieve linkage between the swing rod and the limit rod.

[0016] Optionally, the horizontal cross-section of the leakage pipe is semicircular, the top of the leakage pipe is provided with a circular leakage opening, and the circular leakage opening is provided with an outwardly turned edge.

[0017] By adopting the above technical solution, the horizontal cross-section of the leakage pipe is semicircular, which can be matched with the leakage bucket and is cylindrical as a whole. Water can overflow from one side of the leakage pipe plane and the upper edge of the leakage bucket. The circular leakage port at the top of the leakage pipe is convenient for collecting water, and the setting of the outer flange also facilitates the installation of the leakage pipe.

[0018] Optionally, the leakage bucket is sleeved on the bottom of the leakage pipe, and the inner wall of the leakage bucket is provided with limiting ribs along the axial direction, and the limiting ribs are in contact with the plane of the leakage pipe.

[0019] By adopting the above technical solution and setting the limiting ribs, a guiding effect is played on the cooperation between the leakage bucket and the leakage pipe.

[0020] Optionally, the lowest height of the floating block is higher than the lowest upper edge height of the leaky bucket.

[0021] By adopting the above technical solution, the lowest height of the float, that is, when the float falls naturally and does not float up, represents that the water level in the drain pipe is less than or equal to the height of the float falling naturally. When the amount of water is small, after the drain bucket is lifted, it is ensured that the float can drop. Through the connection between the swing rod and the middle connecting rod, the limit rod is driven to move to limit the floating axis. When the amount of water in the drain pipe increases, before the float plate floats to the highest height, that is, before the limit rod cancels the limit on the floating axis, a large amount of water can be continuously stored in the drain pipe, ensuring that after the drain bucket drops, the initial drainage volume is increased, thereby improving the flushing effect of the drain pipe, drain bucket and downpipe.

[0022] Optionally, the elastic member includes a coil spring.

[0023] By adopting the above technical solution, the coil spring can be sleeved on the floating shaft to improve the elastic force.

[0024] Optionally, a sealing strip is provided at the bottom end of the leakage pipe.

[0025] By adopting the above technical solution and setting the sealing strip, when the leaky bucket is at the highest position, that is, when the inner bottom of the leaky bucket abuts against the bottom end of the leaky pipe, a sealing effect can be achieved to prevent water in the leaky pipe from leaking out, thereby allowing more water to be stored in the leaky pipe.

[0026] In summary, this application has at least the following beneficial effects:

[0027] 1. The present invention provides a lifting device. When a large amount of water is present in the drain pipe and the water level rises, the water and the weight of the drain bucket overcome the elastic force of the elastic member in the floating mechanism, causing the drain bucket to descend, thereby draining a large amount of water and achieving a certain flushing effect. When the water volume decreases, the weight of the water and the drain bucket cannot overcome the elastic force of the elastic member, causing the drain bucket to rise until the water volume in the drain pipe reaches a lower water level. The limiting mechanism then limits the drain bucket, preventing it from descending further. The drain pipe can then store a higher level of water. When the water level reaches a high water level, the limiting mechanism no longer limits the drain bucket, allowing the water and the drain bucket to overcome the elastic force of the elastic member in the floating mechanism and descend, thereby draining water. The above technical solution can achieve water storage, achieve a water seal, and thus achieve a self-sealing effect, preventing gas from escaping from the pipe. The initial amount of water discharged is large, which can achieve a certain flushing effect. It makes it difficult for dirt to adhere to the floor drain and downspout, reduces the possibility of dirt odor, and is less likely to cause blockage. It achieves a certain cleaning effect, reduces the user's cleaning frequency, and improves the use effect.

[0028] 2. The present application can float up and down with the change of water level in the leakage pipe through the setting of the float block, and then drive the swing rod to swing, thereby driving the movement of the limit rod according to the change of water level, thereby achieving the effect of limiting or releasing the limit of the floating axis.

[0029] 3. The lowest height of the float of the present application, that is, when the float falls naturally and does not float up, represents that the water level in the drain pipe is less than or equal to the height of the float falling naturally. When the amount of water is small, after the drain bucket is lifted, it is ensured that the float can drop. Through the connection between the swing rod and the middle connecting rod, the limit rod is driven to move to limit the floating axis. When the amount of water in the drain pipe increases, before the float plate floats to the highest height, that is, before the limit rod cancels the limit on the floating axis, a large amount of water can be continuously stored in the drain pipe, ensuring that after the drain bucket drops, the initial drainage volume is increased, thereby improving the flushing effect of the drain pipe, drain bucket and downpipe.

[0030] 4. A sealing strip is provided at the bottom end of the leakage pipe of the present application. Through the setting of the sealing strip, when the leakage bucket rises to the highest position, that is, when the inner bottom of the leakage bucket is against the bottom end of the leakage pipe, it can play a sealing role to prevent water in the leakage pipe from leaking, thereby allowing more water to be stored in the leakage pipe.

DETAILED DESCRIPTION

[0043] 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.

[0044] The following is combined with Figures 2 to 10 This application is described in further detail.

[0045] The embodiment of the present application discloses a novel self-sealing and odor-proof floor drain.

[0046] Reference Figures 2 to 10 A new type of self-sealing and odor-proof floor drain includes: a leakage pipe 1 and a leakage bucket 2 set at the bottom end of the leakage pipe 1 by a lifting device.

[0047] The horizontal cross-section of the leakage pipe 1 is semicircular. The top of the leakage pipe 1 is integrally formed with a circular leakage opening 3, which is configured with an outwardly turned edge. The leakage bucket 2 is sleeved on the bottom of the leakage pipe 1, and two limiting ribs 4 are provided along the axial direction on the inner wall of the leakage bucket 2. The two limiting ribs 4 respectively contact the two edges of the plane of the leakage pipe 1. The horizontal cross-section of the leakage pipe 1 is semicircular, and it can be matched with the leakage bucket 2, forming an overall cylindrical shape. Water can overflow from one side of the plane of the leakage pipe 1 and from the upper edge of the leakage bucket 2. The circular leakage opening 3 at the top of the leakage pipe 1 facilitates water collection, and the outwardly turned edge also facilitates the installation of the leakage pipe 1. The setting of the limiting ribs 4 plays a guiding role in the matching of the leakage bucket 2 and the leakage pipe 1.

[0048] A sealing strip 5 is provided at the bottom end of the leakage pipe 1. Through the setting of the sealing strip 5, when the leakage bucket 2 rises to the highest position, that is, when the inner bottom of the leakage bucket 2 is against the bottom end of the leakage pipe 1, it can play a certain sealing role, preventing the water in the leakage pipe 1 from leaking out quickly, thereby allowing more water to be stored in the leakage pipe 1.

[0049] The lifting device includes a floating mechanism and a limiting mechanism.

[0050] The floating mechanism includes a fixed block 6, a floating shaft 7, and an elastic member 8. The fixed block 6 is fixedly arranged on the plane of the leakage pipe 1. A top frame 9 is fixedly arranged across the top of the leakage bucket 2, and the top frame 9 spans above the fixed block 6. The top end of the floating shaft 7 is fixedly connected to the middle end of the top frame 9. The lower end of the floating shaft 7 passes through the fixed block 6 in the vertical direction. The elastic member 8 is arranged on the floating shaft 7 between the fixed block 6 and the leakage bucket 2. The elastic member 8 can be a coil spring, and the top and bottom ends of the coil spring are respectively against the top frame 9 and the fixed block 6. The cooperation between the floating shaft 7 and the fixed block 6 plays a guiding role in the lifting and lowering of the leakage bucket 2. The coil spring can directly push the top frame 9 to move upward, thereby pushing the leakage bucket 2 upward.

[0051] By setting up the floating mechanism, the elastic force provided by the coil spring can keep the leaky bucket 2 rising and against the bottom end of the leakage pipe 1. When the water volume increases, the amount of water in the leaky bucket 2 increases, and the weight increases, overcoming the elastic force of the coil spring to make the leaky bucket 2 fall, and drainage is achieved until the water volume decreases, the amount of water in the leaky bucket 2 decreases, the weight decreases, and the coil spring drives the leaky bucket 2 to rise. The weight of the leaky bucket 2 and the water remaining in the leaky bucket 2 and the leakage pipe 1 is balanced with the elastic force provided by the coil spring, or the water volume decreases through evaporation or the like, and the coil spring pushes the leaky bucket 2 to rise until it against the bottom of the leakage pipe 1. At this time, a certain amount of water can be stored in the leakage pipe 1 and the leaky bucket 2, achieving a water seal effect.

[0052] The limiting mechanism is used to limit the descent of the leaky bucket 2.

[0053] The limiting mechanism includes a swing rod 10 , a floating block 11 , an intermediate connecting rod 12 and a limiting rod 13 . On the plane of the leakage pipe 1 below the fixed block 6, a convex body 14 is provided protruding toward the outside of the plane of the leakage bucket 2. The inner side of the convex body 14 is a central control setting. There are two convex bodies 14, which are distributed on both sides of the axial direction of the floating shaft 7. The two swing rods 10 are hinged 1 in the two convex bodies 14 respectively, to realize the hinged up and down swing setting with the leakage pipe 1; the floating block 11 is located in the leakage pipe 1, and the end of the swing rod 10 located in the leakage pipe 1 is fixedly connected to the floating block 11. The hinge axes of the two swing rods 10 are coaxially fixed, and the ends of the two swing rods 10 located outside the leakage pipe 1 are merged into one swing rod 10; a limiting seat 15 is provided on the convex body 14, and a movable through hole is opened on the limiting seat 15. The limiting rod 13 cooperates with the axis of the movable through hole. The head of the limiting rod 13 is wedge-shaped, and the end of the swing rod 10 located outside the leakage pipe 1 is hinged to one end of the intermediate connecting rod 12, and the other end of the intermediate connecting rod 12 is hinged to the limiting rod 13. The limit seat 15 and the movable through hole formed therein can guide the limit rod 13. The swing arm 10 and the limit rod 13 are hingedly connected via the intermediate connecting rod 12, thereby realizing the linkage between the swing arm 10 and the limit rod 13. The floating block 11 can float up and down with the changes in the water level in the leakage pipe 1, thereby driving the swing arm 10 to swing, thereby driving the movement of the limit rod 13 according to the changes in the water level, thereby limiting or releasing the limit of the floating shaft 7.

[0054] The lowest height of the float 11 is higher than the lowest upper edge height of the leak bucket 2. The lowest height of the float 11, that is, when the float 11 falls naturally and does not float up, represents that the water level in the leak pipe 1 is less than or equal to the height of the float 11 falling naturally. When the amount of water is small, after the leak bucket 2 is lifted, it is ensured that the float 11 can drop. Through the connection between the swing rod 10 and the intermediate connecting rod 12, the limit rod 13 is driven to move to limit the floating shaft 7. When the amount of water in the leak pipe 1 increases, before the float plate floats to the highest height, that is, before the limit rod 13 cancels the limit on the floating shaft 7, a large amount of water can be continuously stored in the leak pipe 1, ensuring that after the leak bucket 2 drops, the initial drainage volume is increased, thereby improving the flushing effect of the leak pipe 1, the leak bucket 2 and the downpipe.

[0055] Through the setting of the lifting device, when there is a large amount of water in the leakage pipe 1 and the water level rises, the water and the weight of the leakage bucket 2 overcome the elastic force of the coil spring in the floating mechanism, and the leakage bucket 2 is lowered, thereby achieving a large amount of water discharge, which has a certain flushing effect. When the water volume decreases, the weight of the water and the leakage bucket 2 cannot overcome the elastic force of the coil spring, and the leakage bucket 2 is driven to rise until the water volume in the leakage pipe 1 reaches a lower water level. The limiting mechanism limits the leakage bucket 2, and the leakage bucket 2 can no longer fall, and a higher water level can be stored in the leakage pipe 1. Until the water level reaches a high water level, the limiting mechanism loses the limit on the leakage bucket 2, and the water and the leakage bucket 2 overcome the elastic force of the coil spring in the floating mechanism, and achieve a descent, thereby achieving drainage. Through the above technical solution, water storage can be achieved, water seal can be achieved, and then self-sealing effect can be achieved to prevent gas from being emitted from the pipe. In addition, the initial amount of drainage is large, which can achieve a certain flushing effect, making it difficult for dirt to adhere to the floor drain and the downpipe, reducing the possibility of dirt and odor, and not prone to blockage. It has a certain cleaning effect, reduces the user's cleaning frequency, and improves the use effect.

[0056] Refer to the attached Figures 3 to 5 , the water level in the drain pipe 1 is low (the water level is less than or equal to the lowest position within the swing range of the float 11), or the water evaporates to a lower water level, or there is no water in the floor drain as a whole, the float 11 is at the lowest position, and the limit rod 13 is against the bottom end of the floating shaft 7 for limiting. At this time, it is in the limit state.

[0057] Refer to the attached Figure 6 、 7 There is water in the floor drain, and the water level in the drain pipe 1 reaches the middle water level, driving the float 11 to swing to the middle position within the swingable range. The swing of the swing rod 10 drives the limit rod 13 to move away from the floating shaft 7, but it still resists the bottom end of the floating shaft 7. At this time, it is in the limited state.

[0058] Refer to the attached Figure 8 、 9When the water level in the drain pipe 1 reaches the high water level, the float 11 swings to the highest position within its swing range. The swing of the swing lever 10 causes the limit lever 13 to disengage and abut against the bottom end of the floating shaft 7, resulting in an unrestricted state. This water level is much higher than the leakage height at the upper edge of the drain bucket 2, indicating a large initial leakage volume. This provides a certain flushing effect during drainage.

[0059] Refer to the attached Figure 10 If the water leakage is excessive, the water level in leakage pipe 1 reaches an excessively high level (higher than the highest position within the swing range of float block 11), that is, the water level submerges float block 11. The swing of swing arm 10 causes limit rod 13 to disengage from the bottom end of floating shaft 7, resulting in an unrestricted state. The weight of the water and leaky bucket 2 overcomes the elastic force of the coil spring in the floating mechanism, causing the bucket 2 to drop to its lowest position, achieving maximum drainage.

[0060] As the amount of water discharged gradually decreases, the weight of the water and leaky bucket 2 is unable to overcome the force of the coil spring in the floating mechanism, and leaky bucket 2 begins to rise. When the amount of water in leaky pipe 1 approaches the mid-water level, the weight of the water and leaky bucket 2 is completely unable to overcome the force of the coil spring in the floating mechanism. Leaky bucket 2 is driven to its highest position by the coil spring, where it abuts against the bottom of leaky pipe 1. Simultaneously, the floating plate descends as the water level drops, driving the limit rod 13 toward the floating shaft 7, abutting against the bottom of the floating shaft 7 and limiting the flow. At this point, leaky pipe 1 still holds water at the mid-water level, while leaky bucket 2 also holds water, both acting as water seals. The water level in leaky pipe 1 is higher than that in leaky bucket 2. As the amount of water in leaky pipe 1 increases until it reaches the high water level, the limit rod 13 remains against the bottom of the floating shaft 7, maintaining the limit. This allows leaky pipe 1 to retain a large amount of water, increasing the initial leakage rate the next time it begins to leak.
