Description

Technical Field

[0001] The utility model relates to a floor drain capable of removing hair, and is applicable to the technical field of floor drain processing. Background Art

[0002] Floor drains are a crucial component of a residential drainage system, typically installed between drainage pipes and the ground. Their primary function is to drain accumulated water from bathrooms, balconies, and other areas within a home, while also preventing odor buildup in the sewer. However, during normal use, a significant amount of hair can be carried into the drain by the water flow and become lodged there. Over time, this accumulation not only affects drainage but also makes it prone to rotting, stinking, and breeding bacteria. Existing floor drains, faced with this situation, can only be cleaned manually by removing the drain cover. However, manual cleaning is tedious and can get hands dirty. Furthermore, if the drain is left untreated for an extended period, the drain cover and internal components can easily become stuck, making it difficult to remove. Manual operation can also easily lead to scratches on fingers, resulting in wound infection and a significant safety hazard. Utility Model Content

[0003] In order to solve the defects of the above-mentioned prior art, the utility model provides a floor drain capable of removing hair.

[0004] The technical solution adopted by the utility model is a floor drain capable of removing hair, comprising a floor drain base for being embedded in a sewer pipe outlet, a floor drain cover slidably connected to the floor drain base and raised above the ground, and a shearing mechanism arranged in the floor drain base, wherein the shearing mechanism comprises a pair of cutters slidably arranged in a horizontal direction and opened and closed by relative sliding, a first elastic member applying force to the cutters to close the pair of cutters, a pushing wheel rotatably arranged around a rotating axis arranged in the horizontal direction and used for pushing the pair of cutters to open, and a driving assembly respectively connected to the pushing wheel and the floor drain cover and driving the pushing wheel to rotate by sliding the floor drain cover up and down, wherein the blades of the pair of cutters are arranged to face each other. In the initial state, the pair of cutters are in a closed state under the action of the first elastic member. When hair is brought in by the water flow, it will be stuck above the pair of cutters. Then, by stepping on the floor drain cover, power is provided to the driving component, and the driving component drives the driving wheel to rotate, so that the pair of cutters are opened, and the hair falls between the pair of cutters. When the force applied by the driving wheel to the cutters disappears, the pair of cutters will close again under the action of the first elastic member, and at the same time cut off the hair located therebetween. By repeating this action, the hair accumulated in the floor drain is cut into small segments so that it can be flushed into the sewer pipe by the water flow. Not only does it eliminate the need to manually clean the hair accumulated in the floor drain, avoiding trouble and safety hazards, but it also avoids problems such as poor drainage, bacterial growth, and odor caused by hair accumulation. At the same time, it can also prevent clumps of hair from directly entering the sewer pipe and causing blockage of the sewer pipe, thereby improving the practicality and ease of use of the floor drain.

[0005] Furthermore, each cutter has a handle at one end, and the driving wheel is provided with a plurality of driving blocks. The shearing mechanism has at least two working states. When in the first working state, the driving blocks on the driving wheel are separated from the handles of the pair of cutters, and the first elastic member applies a thrust to the cutters, causing the pair of cutters to close and the blades of the pair of cutters to intersect. When the shearing mechanism is in the second working state, any driving block on the driving wheel is positioned between the handles of the pair of cutters, causing the pair of cutters to open, and the first elastic member is compressed. The driving blocks cooperate with the handles of the cutters to open the pair of cutters, and the plurality of driving blocks on the driving wheel enable the driving wheel to quickly drive the pair of cutters to open and close during rotation, thereby facilitating rapid hair shearing and cutting the hair into finer pieces, thereby preventing clogging of the sewer pipe.

[0006] Furthermore, the floor drain base has a receiving chamber and a drain channel running vertically through it. The driving wheel and drive assembly are located within the receiving chamber, and a pair of cutters are located within the drain channel, with the handle of each cutter extending through the drain channel and into the receiving chamber. Separating the drain channel from the receiving chamber not only facilitates hair removal by the cutters, but also prevents hair or water from adversely affecting the driving wheel and drive assembly, ensuring proper operation of the floor drain.

[0007] Furthermore, the upper portion of the drainage channel is configured to be tapered so as to be larger at the top and smaller at the bottom, thereby enlarging the water inlet of the drainage channel and facilitating the flow of hair to the cutter.

[0008] Furthermore, multiple drainage channels are provided, and the multiple drainage channels are distributed in a circular array around the central axis of the floor drain base. Multiple shearing mechanisms are provided, and the cutters in each shearing mechanism are correspondingly disposed in each drainage channel. The first elastic member is connected between the cutters and the inner wall of the drainage channel. The multiple drainage channels can increase the drainage speed of the floor drain and avoid the problem of poor drainage. The shearing mechanism corresponding to each drainage channel can cut hair flowing into each drainage channel.

[0009] Furthermore, each cutter is arranged in an inward-outward direction, with a handle located at the inner end of the cutter. A driving wheel is located on the inner side of the cutter, rotating around a rotation axis perpendicular to the inward-outward direction. A driving block is located on the outer wall of the driving wheel, with several driving blocks arranged in a circular array around the central axis of the driving wheel. By arranging the positions of the cutters and driving wheels, the internal structure of the floor drain is optimized, the transmission efficiency between the components is improved, and the overall weight of the floor drain is reduced.

[0010] Furthermore, a slide rod is fixed to the center of the bottom surface of the floor drain cover, and a slide groove is formed in the middle of the floor drain base. The slide rod is inserted into the slide groove so as to slide up and down. A second elastic member is sleeved on the slide rod to apply an upward force to the floor drain cover away from the floor drain base. The two ends of the second elastic member are respectively in contact with the floor drain cover and the floor drain base. The elastic force of the second elastic member allows the floor drain cover to return to its original position after the downward pressure disappears, making it convenient for people to repeatedly step on the floor drain cover to drive the cutter to cut hair.

[0011] Furthermore, the driving assembly includes a rack that can be slidably inserted into the floor drain base and the upper end of which is fixedly connected to the floor drain cover, and a gear coaxially fixed to one side of the driving wheel. The gear and the rack are engaged with each other. Through the engagement of the rack and the gear, the up and down sliding of the floor drain cover is converted into the rotation of the driving wheel, thereby realizing the driving of a pair of cutters.

[0012] Furthermore, the drive assembly further includes a spring disposed on another side of the driving wheel for driving the driving wheel to rotate. The spring's ends are respectively secured to the driving wheel and the drain base. When the force exerted by stepping on the drain cover disappears, the spring and the second elastic member jointly exert a force to return the driving wheel and the rack to their original positions. This ensures that the force exerted by the driving wheel in reverse rotation is sufficient to drive the cutter to shear hair, thereby preventing the drain cover from becoming stuck and unable to be ejected due to excessive hair accumulation.

[0013] Furthermore, each cutter has a plurality of blades arranged vertically, and the blades of each pair of cutters are staggered with each other. Through the plurality of blades arranged vertically, the cutter can cut the hair into smaller segments each time, ensuring that the cut hair can be smoothly flushed into the sewer pipe to avoid pipe blockage.

[0014] Due to the application of the above technical solution, the present invention has the following advantages over the prior art:

[0015] The hair-removing floor drain of the present invention provides a shearing mechanism in the floor drain base, which shears the hair brought into the floor drain by the water flow into small pieces, which are convenient for being washed away by the water flow. The shearing mechanism is driven by stepping on the floor drain cover, which not only avoids the problems of poor drainage, bacterial growth, rotting and odor caused by the accumulation of hair in the floor drain, but also avoids the trouble and safety hazards caused by manual cleaning of the floor drain, and also avoids the blockage of the sewer pipe caused by the clumps of hair, thereby greatly improving the practicality and convenience of use of the floor drain.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0025] In the description of this utility model, it should be noted that the directional terms "inner" and "outer" are defined according to the structural orientation of the floor drain. Specifically, the side toward the center of the floor drain is "inner," and the opposite is "outer." The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0027] The shearing mechanism 3 includes a pair of cutters 31 that are slidably arranged in the horizontal direction and open and close by relative sliding, a first elastic member 32 that applies force to the cutters 31 to close the pair of cutters 31, a pushing wheel 33 that is rotatably arranged around a rotating axis arranged in the horizontal direction and is used to push the pair of cutters 31 to open, and a driving assembly 34 that is respectively connected to the pushing wheel 33 and the floor drain cover 2 and drives the pushing wheel 33 to rotate by sliding the floor drain cover 2 up and down. The blades of the pair of cutters 31 are arranged facing each other. The first spring 32 is engaged to remove the hair from the drainpipe, and the second spring 33 is engaged to remove the hair from the drainpipe. Each cutter 31 has a handle 311 at one end, and the driving wheel 33 is provided with a plurality of pushing blocks 331. The shearing mechanism 3 has at least two operating states. When in the first operating state, the pushing blocks 331 on the driving wheel 33 are separated from the handles of the pair of cutters 31, and the first elastic member 32 applies a thrust to the cutters 31, causing the pair of cutters 31 to close and the blades of the pair of cutters 31 to intersect. When the shearing mechanism 3 is in the second operating state, any pushing block 331 on the driving wheel 33 is positioned between the handles 311 of the pair of cutters 31, causing the pair of cutters 31 to open and the first elastic member 32 to be compressed. The pushing blocks 331 cooperate with the handles of the cutters 31 to open the pair of cutters 31. The pushing blocks 331 on the driving wheel 33 enable the driving wheel 33 to quickly drive the pair of cutters 31 to open and close during rotation, facilitating rapid hair shearing and reducing hair fragments to prevent clogging of sewer pipes. The floor drain base 1 has a accommodating chamber 11 and a drainage channel 12 running through from top to bottom. The pushing wheel 33 and the driving assembly 34 are arranged in the accommodating chamber 11. A pair of cutters 31 are arranged in the drainage channel 12, and the handle of each cutter 31 passes through the drainage channel 12 and extends into the accommodating chamber 11. By separating the drainage channel 12 and the accommodating chamber 11, it is not only convenient for the cutter 31 to cut hair, but also avoids the adverse effects of hair or water flow on the pushing wheel 33 and the driving assembly 34, ensuring that the floor drain can be used normally.

[0028] In a more preferred embodiment, the upper portion of the drain channel 12 is configured to be tapered with a larger upper portion and a smaller lower portion, so as to enlarge the water inlet of the drain channel 12 and facilitate the flow of hair to the cutter 31 .

[0029] In a more preferred embodiment, a plurality of sewer channels 12 are provided, and the plurality of sewer channels 12 are distributed in a circular array around the central axis of the floor drain base 1, a plurality of shearing mechanisms 3 are provided, and the cutters in each shearing mechanism 3 are correspondingly arranged in each sewer channel 12, and the first elastic member 32 is connected between the cutter 31 and the inner wall of the sewer channel 12. The plurality of sewer channels 12 can increase the drainage speed of the floor drain and avoid the problem of poor drainage, and the shearing mechanism 3 corresponding to each sewer channel 12 can chop the hair flowing into each sewer channel 12.

[0030] In a more preferred embodiment, each cutter 31 is arranged along the inward and outward directions, the handle 311 is arranged at the inner end of the cutter 31, the pushing wheel 33 is arranged on the inner side of the cutter 31 and rotates around a rotating shaft arranged perpendicular to the inward and outward directions, the pushing block 331 is arranged on the outer wall of the pushing wheel 33, and several pushing blocks 331 are distributed in a circular array around the central axis of the pushing wheel 33. By arranging the setting positions of the cutter 31 and the pushing wheel 33, the internal structure of the floor drain is optimized, the transmission efficiency between the structures is improved, and the overall weight of the floor drain is reduced.

[0031] In a more preferred embodiment, a slide rod 21 is fixed to the center of the bottom surface of the floor drain cover 2, and a slide groove 13 is opened in the middle of the floor drain base 1. The slide rod 21 can be slidably inserted into the slide groove 13. A second elastic member 22 is sleeved on the slide rod 21 to apply an upward force to the floor drain cover 2 to move it away from the floor drain base 1. The two ends of the second elastic member 22 are respectively in contact with the floor drain cover 2 and the floor drain base 1. Through the elastic force of the second elastic member 22, the floor drain cover 2 can return to its original position after the downward pressure disappears, which is convenient for people to repeatedly step on the floor drain cover 2 to drive the cutter 31 to cut hair.

[0032] In a more preferred embodiment, the driving assembly 34 includes a rack 341 that can be slidably inserted into the floor drain base 1 and the upper end of which is fixedly connected to the floor drain cover 2, and a gear 342 coaxially fixed to one side of the pushing wheel 33. The gear 342 is engaged with the rack 341. Through the engagement of the rack 341 and the gear 342, the up and down sliding of the floor drain cover 2 is converted into the rotation of the pushing wheel 33, thereby realizing the driving of a pair of cutters 31.

[0033] In a more preferred embodiment, the driving assembly 34 also includes a clockwork spring 343 arranged on the other side of the pushing wheel 33 and used to drive the pushing wheel 33 to rotate. The two ends of the clockwork spring 343 are respectively fixed to the pushing wheel 33 and the floor drain base 1. When the force of stepping on the floor drain cover 2 disappears, the clockwork spring 343 and the second elastic member 22 jointly apply a force to restore the pushing wheel 33 and the rack 341 to their original positions, ensuring that the force of the reverse rotation of the pushing wheel 33 is sufficient to drive the cutter 31 to cut the hair, thereby avoiding the floor drain cover 2 from getting stuck and unable to pop out due to excessive accumulation of hair.

[0034] In a more preferred embodiment, each cutter 31 has a plurality of blades arranged vertically, and the blades of each pair of cutters 31 are staggered with each other. Through the plurality of blades arranged vertically, the cutter 31 can cut the hair into smaller pieces each time, ensuring that the cut hair can be smoothly flushed into the sewer pipe to avoid pipe blockage.
