Abstract
Description
Technical Field
[0001] This utility model belongs to the field of floor drain technology, specifically relating to a cage-type omnidirectional magnetic levitation floor drain core. Background Technology
[0002] Floor drains are an important component of building drainage systems. They must not only prevent odors and insects and meet daily sanitary drainage needs, but also prevent aerogels carrying pathogens or contaminated gases from backflowing into the room. As a crucial interface connecting the drainage pipe system to the indoor floor, the performance of floor drains directly affects indoor air quality and is extremely important for controlling odors in bathrooms.
[0003] Most floor drains on the market do not have the function of preventing gas from overflowing from the drainage pipe; and the few floor drains on the market that have odor prevention function also use a flip cover to cover the water outlet to isolate the air flow between the drain pipe and the floor drain. However, the flip cover does not have good resilience. After a certain period of use, the flip cover cannot close the water outlet after drainage.
[0004] Currently, there are four main types of floor drain cores on the market: water seal floor drain cores, magnetic levitation or spring T-type floor drain cores, gravity or magnetic flap floor drain cores, and silicone flat tube floor drain cores.
[0005] Water-sealed drain core: It relies on an internal water trap to store a certain amount of water for sealing. It has no sealing effect when there is no water, and the water-sealed structure cannot prevent sewage from overflowing.
[0006] Magnetic levitation or spring-loaded T-type drain cores: The core has a guide mechanism, requiring an additional support structure to secure it. During use, dirt easily accumulates in the gaps of the guide mechanism, causing it to jam and fail to spring back properly, leading to sealing failure and poor drainage. Furthermore, cleaning the dirt from the gaps in the guide mechanism is difficult when a malfunction occurs, requiring regular maintenance over long-term use.
[0007] During use, hair or dirt of a certain length can get tangled on the support structure and guide mechanism. When this dirt extends to the sealing surface, it can cause the seal to fail.
[0008] Gravity / magnetic flap type floor drain core: It has a movable rotating shaft structure. Long-term accumulation of dirt or hair entanglement can cause the rotating shaft to get stuck or jammed, resulting in sealing failure and poor drainage.
[0009] Silicone flat tube drain core: Silicone material is not resistant to dirt when used in humid environments for a long time. It is easy for dirt to stick to the sealing surface and cause the seal to fail. Silicone has poor weather resistance and is prone to aging and deformation after long-term use. After deformation, the sealing part cannot close properly, resulting in seal failure.
[0010] This invention proposes a novel cage-type omnidirectional magnetic levitation floor drain core based on the principle of magnetic levitation. It features a streamlined internal drainage channel, an open bottom structure, and eliminates the need for guiding mechanisms, hinged motion mechanisms, and closed support structures. It requires no other auxiliary sealing components, relying solely on direct contact between structural elements to achieve a seal. This effectively drains easily entangled debris such as hair and lint, and provides strong protection against insects, odors, and aerogel-induced sewage backflow. It is maintenance-free for extended periods. This invention effectively addresses the various shortcomings and drawbacks of existing floor drain cores. Utility Model Content
[0011] The purpose of this invention is to provide a cage-type omnidirectional magnetic levitation drain core, which has a streamlined internal sewage channel, an open bottom structure, no guiding mechanism, hinged motion mechanism, or closed support structure, and no other auxiliary sealing parts. It achieves sealing solely through direct contact between structures. It can effectively discharge easily tangled dirt such as hair and thread ends, and has strong insect-proof, odor-proof, and aerogel sewage backflow prevention capabilities. It can be maintenance-free for a long time and can effectively block odors from overflowing from the drain pipe.
[0012] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:
[0013] A cage-type omnidirectional magnetic levitation drain core includes a core body, a ball cage, a float, a fixed magnetic block, and a floating magnetic block;
[0014] The core is a cylindrical body with openings at both ends and an inner cavity in the middle. The inner cavity penetrates the upper and lower end faces of the core. A hanging ring is provided on the outer edge of the upper end face of the core for limiting and fixing during installation.
[0015] The lower end of the core is provided with a connecting ring; the upper end of the connecting ring is provided with a fixed magnetic block; preferably, the fixed magnetic block is an annular magnetic block, which is horizontally arranged and sleeved on the outer wall of the connecting ring.
[0016] The lower end of the connecting ring is connected to the ball cage, which can be done by threaded connection or snap-fit connection.
[0017] The core and connecting ring are integrally molded.
[0018] The ball cage includes a connecting ring and several cage claws; the connecting ring is an annular shell with a cavity in the middle for installation and fixation with the connecting ring.
[0019] The plurality of cage claws are evenly distributed and vertically fixed to the bottom of the connecting ring; the connecting ring and the cage claws are integrally formed.
[0020] Side drain outlets are provided between adjacent cage claws; bottom drain outlets are provided at the bottom of the enclosure formed by several cage claws.
[0021] The bottom of the cage claws is equipped with a closing limiting claw; the central area enclosed by several cage claws is a float movement cavity for the float to float up and down. The diameter of the bottom drain outlet and the side drain outlet is smaller than the diameter of the float.
[0022] The float is located inside the float's movable cavity;
[0023] The float is a sphere with a smooth spherical surface, and a floating magnetic block is fixed at its upper end. The floating magnetic block can be fixed to the upper surface of the float or located inside the float. The floating magnetic block can be fixed or in a free state.
[0024] The fixed magnetic block attracts the floating magnetic block.
[0025] The core body has a limiting bevel at its bottom end, the diameter of which is smaller than that of the float. The inner wall of the limiting bevel is arc-shaped, which fits tightly to the outer spherical surface of the float. The limiting bevel is used to prevent the float from sliding out from the top, and the closing limiting claw is used to prevent the float from sliding out from the bottom.
[0026] Briefly describe its working principle:
[0027] The fixed magnetic block and the floating magnetic block attract each other. As the floating magnetic block moves upward toward the fixed magnetic block, it causes the float to come into contact with the bevel of the core, forming a sealing surface.
[0028] (1) Drainage status
[0029] When sewage is discharged from the core, sewage accumulates inside the core. When the weight of the sewage (with float and floating magnetic block) is greater than the magnetic force of the fixed magnetic block on the floating magnetic block, the sewage pushes the float to move down, and the float and the limiting bevel change from contact to separation, the sealing surface opens, and the sewage is discharged.
[0030] After the sewage is discharged, the float returns to its original position under the magnetic force of the mutual attraction between the floating magnet and the fixed magnet. The float then contacts the bevel of the core to form a sealing surface and restores the sealing state.
[0031] There are no non-streamlined protrusions in the sewage discharge channel, and the bottom of the ball cage has an open structure, so dirt, hair, and thread can be completely removed by the water flow.
[0032] (2) Anti-backflow status
[0033] When gas or sewage overflows upwards from the pipe, the pressure or buoyancy brought by the overflow increases the clamping force between the float and the limiting bevel, strengthening the seal and effectively preventing the overflow of gas and sewage.
[0034] (3) Same-floor drainage status
[0035] When sewage from other pipes on the same floor flows through the float, the float experiences an upward buoyancy, which increases the pressure between the float and the bevel of the core, strengthens the seal, and effectively prevents sewage from overflowing during sewage discharge on the same floor.
[0036] Compared with the prior art, this application has the following advantages:
[0037] 1. No hinged parts, no guiding mechanism:
[0038] Compared with traditional mechanical and magnetic levitation floor drains, this type of drain has no hinged parts or guide mechanisms. It eliminates the problems caused by dirt accumulating inside the hinges and guide mechanisms during long-term use, which can lead to jamming, sealing failure, and drainage malfunction.
[0039] 2. Open, streamlined sewage discharge channel:
[0040] The sewage channel is streamlined and has no protruding fixed structures to obstruct it, ensuring smooth sewage discharge. The bottom has an open structure, which can easily discharge easily tangled waste such as hair and thread ends.
[0041] 3. Omnidirectional magnetic levitation:
[0042] Unlike traditional magnetic levitation systems that require magnets to move a float in a specific direction to form a seal, this invention only requires the magnets to generate an effective magnetic force that moves the float closer to the bevel of the core to form an effective seal.
[0043] 4. New type of float:
[0044] A float is a combination of a buoy and a floating magnet. The buoy can be spherical, spindle-shaped, bell-shaped, or a combination of several shapes, and non-traditional perfectly spherical floats are also possible. The floating magnet inside the buoy can be fixed to the buoy or can be in a free-moving state within a hollow buoy.
[0045] 5. Self-sealing design:
[0046] Under the action of magnetic force, the float can form an effective seal whether it is vertical or tilted. It can achieve a dry and wet seal without external conditions. The backflow of gas and sewage from the sewer pipe helps to enhance the seal, making it more effective than traditional floor drains.
[0047] The beneficial effects of this utility model are as follows:
[0048] Its internal streamlined sewage channel and open bottom structure have no guiding mechanism, hinged motion mechanism, or closed support structure. It has no other auxiliary sealing parts and relies solely on direct contact between structures to achieve sealing. It can effectively discharge easily tangled dirt such as hair and thread ends. It has strong insect-proof, odor-proof, and aerogel sewage backflow prevention capabilities and can be maintained for a long time without maintenance. It can effectively block the odor overflowing from the sewer pipe. Attached Figure Description

[0060] The core 1 and the connecting ring 12 are integrally formed.
[0061] The ball cage 2 includes a connecting ring 21 and several cage claws 22; the connecting ring 21 is an annular shell with a cavity 20 in the middle for installation and fixation with the connecting ring 12.

[0067] like Figure 6 As shown, the fixed magnetic block 4 attracts the floating magnetic block 5. The magnetic pole arrangement between the fixed magnetic block 4 and the floating magnetic block 5 typically falls into the following categories:
