Description

Technical Field

[0001] The invention belongs to the technical field of drainage pipe systems, and relates to a floor drain, and in particular to a magnetically closed and drainable water film sealed and odor-resistant floor drain core. Background Art

[0002] The floor drain is an important interface between the drainage pipe system and the indoor floor. As an important component of the drainage system in a house, the floor drain should have two basic functions: one is smooth drainage, which can quickly remove water on the ground; the other is good sealing performance, which can effectively prevent odors in the sewer pipe from entering the room; therefore, the performance of the floor drain directly affects the quality of indoor air and people's quality of life.

[0003] At present, there are many types of floor drains available, and the main types are three. The first type is an ordinary flip-type anti-gravity floor drain. The anti-gravity block of this floor drain usually adopts a larger iron block, and the iron block is located at the end of the cover plate, resulting in a smaller opening at the water outlet of the floor drain core, resulting in defects such as slow drainage and poor sealing performance.

[0004] The second type is a magnetic anti-gravity floor drain, which provides sealing force to the cover plate through the gravity of the anti-gravity block and the attraction of the magnet. However, the existing magnetic floor drain has a complex magnet distribution structure, a high manufacturing cost, and the magnet mounting part is not waterproof, resulting in a part of the magnet being exposed in a wet pipe, which seriously affects its service life. In addition, the existing magnetic floor drain has a small drainage volume and poor drainage effect, which cannot meet the market demand.

[0005] The third type is a magnetic levitation floor drain core, which includes a core body and a seal. The upper part of the core body is provided with a water inlet, the side is provided with a water outlet, and the bottom is provided with a magnet. The magnet and the magnet of the seal form a repulsive force to achieve the sealing of the water inlet. In addition, there are 1-2 or more connecting ribs between the core body and the seal. During long-term use, the connecting ribs are easily entangled by debris such as hair, which can easily cause blockage and deteriorate the sealing performance. At the same time, the structure is relatively complex and the manufacturing cost is high.

[0006] Therefore, there is a lack of a floor drain and floor drain core on the market that can comprehensively solve the above problems. Summary of the invention

[0017] Compared with the prior art, this magnetic closed and drained water film sealed and odor-proof floor drain core has the following advantages:

[0018] 1. The magnetic closed and drain-free water film sealed and odor-proof floor drain core is designed with two magnetic distribution structures, both of which are provided with a magnetic active unit with a first permanent magnet located on the limit part to push the magnetic closed cover plate to seal the water outlet, and use magnetic force to make the soft sealing gasket close to the edge of the water outlet, which can achieve a good sealing effect and effectively prevent the odor in the pipe from overflowing. It is also provided with two magnetic distribution structures, which effectively meets the market demand.

[0019] 2. The magnetically closed and drainable water film sealed and odor-proof floor drain core is provided with an annular flange at the edge of the soft sealing pad, which cooperates with the annular concave arc at the edge of the water outlet, and there is a small gap range at the matching contact part between the annular flange and the annular concave part. A small amount of liquid can be stored in the gap, and a water film sealing state can be formed by storing a small amount of liquid in the gap, thereby enhancing the sealing effect of the magnetic closed cover plate and the water outlet, and effectively preventing the odor from overflowing from the pipe.

[0020] 3. The magnetic closed and drain-free water film sealed and odor-proof floor drain core is provided with sealing covers in the accommodating groove 1, the accommodating groove 2 and the sealed accommodating cavity, and the first permanent magnet, the second permanent magnet and the third permanent magnet are all embedded and installed in the corresponding sealing covers. It not only effectively prevents the magnets from rusting due to exposure to humid pipe air, thereby further leading to magnetic weakening or demagnetization and affecting the sealing performance, but also prolongs the service life of the floor drain core and promotes better drainage effect.

[0021] 4. The magnetic closed and drained water film sealed and odor-proof floor drain core has a soft pad integrally injection-molded at the bottom of the positioning shoulder, and the soft pad can increase the sealing performance between the floor drain core body and the floor drain. Compared with the traditional floor drain core, the service life of the floor drain core is greatly increased.

[0022] 5. Compared with the traditional magnetic floor drain core, the magnetic closed and drain-free water film sealed and odor-proof floor drain core adopts two mutually attractive magnetic distribution structures. The magnetic distribution structure is more evenly distributed and enhances the sealing performance of the magnetic closed cover plate and the water outlet, which greatly increases the service life of the floor drain core and promotes better drainage effect.

[0023] 6. The magnetic closed and drain-free water film sealed and odor-proof floor drain core utilizes the magnetic structure distribution of the first permanent magnet and the second permanent magnet attracting each other and repelling each other with the third permanent magnet, so that the magnetic field distribution on the magnetic power shaft and the limiting part is more uniform, and three sealed magnetic chambers for the corresponding permanent magnets to be fixedly installed can be formed between the accommodating groove one, the accommodating groove two and the sealed accommodating cavity and the corresponding sealed cover plate, and the three sealed magnetic chambers and the permanent magnets located in the three sealed magnetic chambers can form a magnetic field operation structure, and the magnetic field operation structure can realize the conversion of magnetic force into the mechanical sealing force of the magnetic closure cover plate, thereby avoiding the failure of the magnetic closure cover plate to seal the water outlet during the use of the floor drain core, improving the sealing reliability of the magnetic closure cover plate, making the magnetic closure cover plate fit closely with the edge of the water outlet, and achieving the purpose of rapid drainage and closing at the same time, realizing the ultimate effect of opening and closing.
