Abstract
Description
Technical Field
[0001] This invention relates to the field of floor drain technology, and more particularly to a floor drain. Background Technology
[0002] Floor drains are an indispensable part of bathroom decoration and play a vital role in bathroom drainage. They can achieve functions such as overall insect prevention and odor reduction, and prevent sewer backflow, ensuring bathroom cleanliness and providing a healthy and comfortable living environment.
[0003] Hair accumulation and blockage are the main causes of clogged drains, leading to the growth of dirt and bacteria. Therefore, most floor drain products on the market currently use a mesh screen to prevent hair and other foreign objects from being flushed into the sewer. However, this requires users to clean the floor drain by hand frequently. Faced with a floor drain that has been breeding bacteria for a long time and has an odor, users often feel disgusted and refuse to clean it, but they have no choice but to do so.
[0004] Cutting and flushing away hair flowing into the drain has become a solution for clogging sewer pipes. However, current hair-cutting drain products still cannot achieve long-term stable operation and have the following problems: the hair-cutting device is difficult to use, resulting in a poor user experience; the product often protrudes from the ground, making it easy for users to trip; the installation location is limited, and it cannot handle animal hair or effectively cut materials such as paper and yarn; the product is unstable in long-term use, and its internal structure cannot be cleaned.
[0005] There is a lack of floor drains in the current technology that meet the needs of users.
[0006] The above background information is provided only to aid in understanding the concept and technical solution of this invention. It does not necessarily belong to the prior art of this patent application. In the absence of clear evidence that the above information was disclosed on the filing date of this patent application, the above background information should not be used to evaluate the novelty and inventiveness of this application.

[0028] like Figure 1 As shown, the present invention provides a floor drain, including a floor drain cover 1, a housing 12, a stamping unit, and a cutting unit;
[0029] The drain cover 1 has a hole, and the edge of the hole is fixedly connected to the upper edge of the housing 12.
[0030] The housing 12 includes a receiving cavity; the receiving cavity is used to accommodate the stamping unit and the cutting unit, the stamping unit being suspended relative to the cutting unit;
[0031] The top of the stamping unit is placed inside the hole and is flush with the ground where the drain cover 1 is located. When the top of the stamping unit is subjected to force, it moves downward and contacts the cutting unit.
[0032] It is understood that the drain cover of the present invention is a ground water guide plate with a slightly concave center. The shape, color, and material of the water guide plate are not limited and can be selected according to home decoration needs. When in use, water on the ground carries solid impurities into the drain through the holes in the drain cover. The solid impurities of the present invention can be human hair, animal hair, paper, yarn, etc. Users only need to apply pressure to the stamping unit to cut these solid impurities, realize the anti-clogging function, and use it quickly and conveniently.
[0033] In this invention, the suspended arrangement of the stamping unit and the cutting unit ensures that sufficient space is reserved for smooth and rapid drainage.
[0034] Furthermore, the drain in this invention is flush with the ground rather than protruding from it, making it more convenient to use.
[0035] Furthermore, the drain of the present invention occupies little space, has a simple structure, and performs well.
[0036] Preferably, the main body material of the floor drain in this invention can be made of corrosion-resistant and rust-proof metals such as stainless steel or brass, and the surface can be plated with a wear-resistant layer, a rust-proof layer, etc., to ensure the working strength and stability of the floor drain product.
[0037] In a specific embodiment of the present invention, in order to achieve the suspension of the stamping unit and the cutting unit, the stamping unit includes a first magnetic element 5 and the cutting unit includes a second magnetic element 11; the first magnetic element 5 and the second magnetic element 11 have the same magnetism, and the stamping unit is suspended relative to the cutting unit based on the repulsion of like poles.
[0038] In one embodiment of the present invention, the first magnetic element and the second magnetic element are permanent magnets.
[0039] It is understood that other existing methods that can generate levitation can also be applied to this invention.
[0040] like Figure 1 As shown, the stamping unit also includes: a lower pressure cover plate 2, a lower pressure sliding tube 3, and a rubber stamping head 6;
[0041] The lower pressure cover plate 2 is fixedly connected to the lower pressure sliding tube 3, and a first sliding fixing part 4 is provided on the outer wall of the lower pressure sliding tube 3;
[0042] The bottom of the downward sliding tube 3 is provided with the first magnetic element 5, and the rubber stamping head 6 is wrapped around the outside of the first magnetic element 5.
[0043] Continue as Figure 1 As shown, the cutting unit also includes a sliding support sleeve 8, a support frame 9, and a cutting component 10;
[0044] The inner wall of the sliding support sleeve 8 is provided with a second sliding fixing part 7 corresponding to the first sliding fixing part 4, and the support frame 9 is fixedly provided on the outer wall. The support frame 9 is fixedly connected to the housing 12. The cutting part 10 is provided on the lower part of the sliding support sleeve 8. The cutting part 10 is engaged with the second magnetic part 11. In a specific embodiment, the second magnetic part 11 is annular to facilitate engagement with the cutting part 10, and the second magnetic part 11 is engaged with the housing 12.
[0045] In one embodiment of the present invention, the first sliding fixing part 4 and the second sliding fixing part 7 are externally adapted to each other, for example, they can be structurally adapted concave and convex, and the quantity is also adapted to each other, which can ensure that the stamping unit can move vertically up and down. Furthermore, the inner wall of the sliding support sleeve 8 and the lower sliding tube 3 need to be sufficiently smooth, and lubricating oil can be added to facilitate stepping up and down.
[0046] In this invention, the housing 12 is stepped from top to bottom, which can be adapted to drainage pipes of different diameters, such as the currently mainstream 40mm, 50mm and 75mm. The entire housing 12 is hollow to form a receiving cavity to accommodate the stamping unit and the cutting unit, and is adapted to the components of the stamping unit and the cutting unit. The inner wall of the receiving cavity abuts or snaps against the stamping unit and the cutting unit to ensure that the stamping unit and the cutting unit do not leave the center and work stably.
[0047] Although animal hair tends to clump together easily, the cutting unit of this invention is sufficient to cut it into fragments for disposal in the sewer system because the cutting element in this invention is a mesh composed of multiple blades, which are made of stainless steel or ceramic.
[0048] It is understood that the blades themselves can be wavy or straight, and multiple blades can be arranged in parallel and equidistant or unequally spaced in one direction, or they can be arranged in two directions to form a grid, fishbone, or any other shape, or they can be arranged in multiple directions, such as in a radial pattern. This invention only needs to ensure that the interval between two adjacent blades in the blade mesh formed by multiple blades is 8-12mm, so as to better cut solid impurities.
[0049] In another embodiment of the present invention, the blade mesh is concave in the middle and higher around the edges, and the rubber stamping head 6 is matched with the blade mesh, so that solid impurities can easily gather in the center of the blade mesh, thereby enhancing the force and achieving a better chopping effect.
[0050] During use, when solid impurities remain on the blade mesh, stepping on the pressing cover plate 2 causes the rubber head 6 to press down onto the blade mesh, cutting the solid impurities into small pieces. The rubber pressing head 6 can be replaced as it is worn out, and is preferably made of wear-resistant material.
[0051] Continue as Figure 1 As shown, in another embodiment of the present invention, the floor drain further includes an odor-proof and backflow-proof unit, which is placed in the receiving cavity of the housing and includes: an odor-proof one-way valve body 13, an odor-proof valve magnet 14, and an odor-proof valve switch 15;
[0052] The odor-proof one-way valve body 13 is snapped into the housing 12, and the odor-proof valve switch 15 is provided at the lower part. The odor-proof valve switch 15 is provided with the odor-proof valve magnetic component 14 inside. The odor-proof valve magnetic component 14 has opposite magnetism to the second magnetic component 11. The opposite poles are placed opposite each other to ensure that the odor-proof and anti-backflow unit has good sealing performance when no water is flowing, thereby achieving the purpose of odor prevention and anti-backflow.
[0053] Furthermore, a thin layer of silicone can be applied between the various connecting parts of the odor-proof and anti-backflow unit to enhance airtightness and prevent odor.
[0054] Figures 2(a) and 2(b) show schematic diagrams of the floor drain in both static and operational states in an embodiment of the present invention. When using the floor drain of the present invention, simply connect the drain housing 12 to the drain pipe in a sealed manner. The drain cover 1 is flush with the ground. Stepping down on the pressing unit engages with the cutting unit; specifically, stepping down on the cover plate will trigger the hair-breaking function. To replace the wear-resistant pressing rubber head, simply remove the floor drain and replace the rubber head. In special circumstances, the pressing unit portion of the floor drain can be removed for internal processing.
[0055] This invention achieves hair-cutting function by setting the stamping unit and cutting unit in a suspended configuration and using a low-cost, purely mechanical method. It can effectively cut various solid impurities such as hair, paper, and yarn, thereby preventing sewer blockage. Users no longer need to pick up the dirt by hand; they only need to step on the lower cover to complete the cutting operation, which is time-saving and labor-saving, and provides a good user experience.
[0056] Furthermore, the floor drain provided by this invention has no installation scenario or area restrictions, is flush with the ground, does not interfere with the user's movement, is very easy to install, can be adapted to various pipe types, and is relatively safe to use.

[0058] The features disclosed in the several method or device embodiments provided in this application can be arbitrarily combined without conflict to obtain new method or device embodiments.
[0059] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various equivalent substitutions or obvious modifications can be made without departing from the concept of the present invention, and all such modifications, achieving the same performance or application, should be considered within the scope of protection of the present invention.
