[0001] The utility model belongs to the technical field of floor drains, in particular to a magnetic deodorizing floor drain core. Background Art
[0002] The floor drain is an important interface between the drainage pipe and the indoor floor. As an important part of the drainage system, the floor drain is widely used in the bathroom, public bathhouse and all indoor places that need drainage. The floor drain core is the core part of the floor drain, which can be detached and installed on the floor drain seat.
[0003] Traditional floor drain cores are generally open and cannot prevent the leakage of sewer odors. In order to solve the problem of sewer odor and improve the anti-odor ability, an anti-odor floor drain core was later developed. For example, the invention patent with application number 202310613412.1 discloses an anti-odor floor drain core, including a drain core body and a cover plate. The drain core body is provided with a connected water inlet and water outlet. The cover plate is hinged on the drain core body and can open and close the water outlet. The drain core body is provided with a fixed magnet, and a moving magnet corresponding to the fixed magnet is arranged on the cover plate. The mutual force between the moving magnet and the fixed magnet can push the cover plate toward the water outlet; the water outlet and the cover plate are sealed by a sealing ring; a positioning groove is arranged on one side of the cover plate close to the water outlet, and the sealing ring is arranged in the positioning groove; the sealing ring has an inner ring and an outer ring, the inner ring and the outer ring are connected by a deformable membrane flap, the positioning groove limits the inner ring, the outer ring can be pressed against the water outlet, and there is a deformation interval between the outer ring and the cover plate.
[0004] The sealing ring and cover plate of the above-mentioned odor-proof floor drain core are fixed by snap connection. As the usage time increases, the continuous flushing by cold water, warm water and hot water will cause the connection between the sealing ring and the cover plate to loosen, thereby affecting the sealing between the cover plate and the drain core body, and even the sealing ring may fall off completely. Summary of the invention
[0005] In view of the deficiencies in the prior art, the utility model aims to provide a floor drain core with longer service life and better sealing performance.
[0006] The purpose of the utility model can be achieved through the following technical solutions:
[0007] A magnetic odor-proof floor drain core, comprising a drain core body and a cover plate made of plastic, wherein a water inlet is provided at the upper end of the drain core body and a water outlet is provided at the left side of the lower end, and the water inlet and the water outlet are connected. The invention is characterized in that an assembly part is formed on the right side of the cover plate, the assembly part and the right side of the lower end of the drain core body are hinged, a fixed magnet is fixedly connected to the right side of the lower end of the drain core body, a moving magnet is fixedly connected inside the assembly part, the interaction force between the fixed magnet and the moving magnet can push the cover plate to close the water outlet, a sealing gasket made of rubber is fixedly connected to the side of the cover plate close to the water outlet, and the sealing gasket and the cover plate are formed into an integrated structure.
[0008] The sealing gasket and the cover plate in the core of the magnetic deodorizing floor drain are formed into an integrated structure. Specifically, the formed cover plate is placed in a mold, and then rubber is injected to melt and mold the sealing gasket made of rubber onto the cover plate. The connection between the cover plate and the sealing gasket made in this way is more secure, and the sealing gasket and the cover plate are not easy to separate or loosen, so the sealing performance is better and the service life is longer.
[0009] In the above-mentioned magnetic odor-proof floor drain core, the edge of the cover plate is bent downward to form an annular step, the sealing gasket is injection molded on the annular step, and the inner edge of the sealing gasket is molded with an upwardly protruding annular ridge, which protrudes from the upper side of the cover plate and can be inserted into the water outlet of the drain core body.
[0010] The design of the annular step can not only increase the contact area between the cover plate and the gasket, making the connection between the gasket and the cover plate more secure, but also limit the gasket horizontally, further increasing the secureness of the connection between the gasket and the cover plate; further, the design of the annular step can also increase the structural strength of the cover plate, making the cover plate less likely to deform after long-term use. The design of the annular convex edge can play a positioning role when the cover plate and the floor drain body are sealed, preventing the cover plate from sliding relative to the floor drain body after sealing, thereby affecting the sealing effect.
[0011] In the above-mentioned magnetic deodorizing floor drain core, the distance D between the annular protrusion and the outer edge of the sealing gasket is greater than the wall thickness L of the drain core body at the drain outlet.
[0012] The above design can ensure that the sealing gasket can seal the water outlet, improve the sealing effect, and make the magnetic deodorizing floor drain have a better deodorizing effect.
[0013] In the above-mentioned magnetic deodorizing floor drain core, the right edge of the annular step is bent upward to form a peripheral edge, the peripheral edge is fixedly connected to the assembly portion, and the sealing gasket and the left side wall of the peripheral edge are formed into an integrated structure.
[0014] The above-mentioned surrounding edge design can not only increase the contact area between the sealing gasket and the cover plate, making the connection between the sealing gasket and the cover plate more secure after injection molding, but also enhance the firmness of the connection between the cover plate and the assembly part, thereby increasing the service life of the cover plate.
[0015] In the above-mentioned magnetic odor-proof floor drain core, two vertical mounting plates are fixed on the right side of the lower end of the drain core body, pin holes are arranged on the mounting plates, and pin shafts are formed on the front and rear sides of the upper left side of the assembly part. The assembly part is installed between the two mounting plates, and the pin shaft can be inserted into the pin hole and enable the assembly part to rotate around the pin shaft relative to the mounting plate.
[0016] The pin hole on the mounting plate cooperates with the pin shaft of the assembly part, so that the cover plate can rotate around the pin shaft, wherein the pin shaft is fixed to the upper left part of the assembly part, so that the assembly part can play the role of a counterweight block, so that the fixed magnet can exert a smaller force on the moving magnet to ensure that the cover plate seals the water outlet, which is beneficial to improving the deodorizing effect and ability of the magnetic deodorizing floor drain core, and even if the magnetic force of the fixed magnet and the moving magnet weakens after long-term use, the cover plate can also be closed normally, which is beneficial to improving the service life of the magnetic deodorizing floor drain core.
[0017] In the above-mentioned magnetic odor-proof floor drain core, a mounting block is arranged between the two mounting plates, a mounting groove is arranged on the lower side of the mounting block, the fixed magnet is fixedly connected in the mounting groove, the polarities of the fixed magnet and the moving magnet on opposite sides repel each other, and when the cover is closed, the angle α between the lower side of the mounting block and the upper side of the assembly part ranges from 40° to 90°.
[0018] The angle α between the lower side of the mounting block and the upper side of the assembly portion is close to or equal to the angle at which the cover can rotate. When the angle α is within the range of 40-90 degrees, it can ensure that sewage can pass better when the cover is opened, and can also ensure that after no water flows through, the cover can be smoothly closed under the repulsive force of the fixed magnet and the moving magnet.
[0019] In the above-mentioned magnetic deodorizing floor drain core, the water outlet is arranged to be lower on the left and higher on the right.
[0020] The water outlet is tilted with the left side lower and the right side higher, which not only increases the water outlet area, but also, when the water flow is small, most of the water will flow out from the left side of the water outlet under the action of gravity, preventing dirt in the water from getting stuck in the connection between the cover and the leakage core body, thereby preventing dirt in the water from affecting the smooth closing of the cover, which is beneficial to further improve the sealing effect and service life.
[0021] In the above-mentioned magnetic deodorizing floor drain core, a pull ring is included, and two protrusions are symmetrically arranged on the upper end of the drain core body. The protrusions are provided with through holes, and the two ends of the pull ring are respectively extended into the corresponding through holes and are rotatably connected to the protrusions.
[0022] The design of the protrusion and the pull ring facilitates the taking and placing of the floor drain core, and is convenient for installation, replacement and maintenance.
[0023] In the above-mentioned magnetic odor-proof floor drain core, the drain core body includes a mounting portion, a contraction portion and a water outlet portion from top to bottom in sequence, the water inlet is arranged at the upper end of the mounting portion, and at least two sealing grooves for installing a sealing ring are arranged on the outer peripheral wall of the mounting portion along its axial direction.
