Description

Magnetic repulsion floor drain

Technical field:

the invention belongs to the technical field of drainage equipment, and particularly relates to a magnetic repulsion floor drain.

The background technology is as follows:

the floor drain is a necessary structure for toilets, kitchens, washing machines and the like, and has the function of connecting a drain pipe with the indoor ground so that water directly flows to the drain pipe from the indoor ground. When the existing magnet type floor drain works, when water flows into the floor drain to reach a certain water quantity, the gravity of the water is larger than the suction force of the magnet, the water can open the bottom sealing cover of the floor drain, the water flows into the drainage pipeline through the floor drain, when the water flow is interrupted, the water is not pressed downwards enough, and the rubber sealing gasket is automatically closed under the action of the magnetic suction to realize sealing. However, after the floor drain sealing cover is used for a period of time, impurities such as hair and the like often block the magnet at the sealing position, the impurity layer can cause the floor drain sealing cover to be incapable of being closed, and gas in the drain pipe can enter a room, so that the conditions of smell returning and bacterial and insect pollution occur.

The following conventional floor drain has corresponding advantages and disadvantages. The silica gel floor drain core is opened when water is introduced, and is closed when water is not introduced, so that the structure is simple. However, after a period of use, impurities such as hair are easy to adhere to the wall, so that the silica gel is not tightly closed, and the odor is reversed.

The inner core water seal type floor drain core has the advantages that when the floor drain does not flow into water or is in a water seal free state for a quite long time, double protection can be achieved, odor is not reversed, and insects are not fed; however, the silica gel of the inner core is easy to age after being soaked in water for years, and needs to be replaced once in a few years, so that the cost is high.

When the floor drain is drained, the gravity turns over the plate to automatically open, and when the water is not filled, the plate turns over to close, so that the odor and insects are prevented, but after a period of time, the closing becomes insensitive, and the effect of the floor drain core is invalid.

The siphon floor drain is characterized in that the siphon floor drain is bent from the S and is deodorant, water is drained under the action of air pressure during siphon, but the siphon floor drain has the defects of small pipe diameter and easy blockage by foreign matters, intermittent drainage is adopted, a part of water is needed to be collected and then the siphon action is generated to drain the water, and the siphon generation cannot be completely guaranteed in the prior art.

The invention comprises the following steps:

the invention aims to provide the floor drain which is easy and convenient to assemble and disassemble and can prevent the odor from reflecting and bacteria and insect from magnetic repulsion through the formed water seal. The floor drain inner core and the drain vertical pipe of the floor drain are detachably arranged, and the grate and the floor drain inner core are detachably arranged; the fixed magnet and the conical magnet have the same magnetism and repel each other, and sealing is realized through magnetism. The floor drain has the advantages of good tightness, difficult destruction of the water seal, capability of effectively preventing insects and flies in the pipeline and gas from entering and exiting the room, convenience in mounting and dismounting, convenience in cleaning, smooth drainage and difficult blockage.

Further, the length of the floor drain inner core is 60mm-70mm.

Further, the included angle between the conical surface of the conical magnet and the horizontal plane is 40-50 degrees.

Further, the included angle between the conical surface of the conical magnet and the horizontal plane is 45 degrees.

Further, the conical filter screen is provided with uniformly arranged overflow holes, the width of each overflow hole is 5mm, and the length of each overflow hole is 20mm.

Further, the number of the overflow holes is 10-12.

Further, the conical magnet is positioned in the center of the floor drain under the action of the support and the magnetic repulsive force of the two support posts.

Further, when the floor drain inner core is filled with water, the sum of the gravity of the water and the gravity of the conical magnet is smaller than the repulsive force exerted by the conical magnet, the conical magnet is tightly attached to the bottom of the floor drain inner core, and a water seal is formed on the floor drain inner core; when the sum of the gravity of water in the floor drain inner core and the gravity of the conical magnet is larger than the repulsive force borne by the conical magnet, the conical magnet sinks to the supporting plate, and water flows through a gap between the conical filter screen above the conical magnet and below the inner core; when water does not enter the inner core of the floor drain any more, the conical magnet ascends under the repulsive force effect to be tightly closed with the inner core of the floor drain, and at the moment, the indoor space is isolated from the drainage pipeline. The floor drain has the advantages of good tightness, difficult destruction of the water seal, capability of effectively preventing insects and flies in the pipeline and gas from entering and exiting the room, convenience in mounting and dismounting, convenience in cleaning, smooth drainage and difficult blockage.

The specific embodiment is as follows:

example 1

Referring to fig. 1-3, a magnetic repulsion floor drain comprises a grate 1, a floor drain inner core 5, a conical magnet 3, a supporting plate 6, a fixed magnet 4 and a floor drain shell 7; the floor drain shell 7 is detachably arranged on the drain vertical pipe 9 in a seat mode, the floor drain inner core 5 is detachably embedded on the floor drain shell 7, the grate 1 is detachably embedded on the floor drain inner core 5, and a conical filter screen 2 is arranged at the bottom of the floor drain inner core 5; a conical magnet 3 is arranged below the conical filter screen 2, and a rubber sealing gasket 8 is arranged on the conical surface of the conical magnet 3; the fixed magnets 4 are embedded on the conical surface of the lower part of the floor drain shell 7, and the supporting plates 6 are positioned above the fixed magnets 4, are three in number and are uniformly distributed; the magnetic properties of the conical magnet 3 and the fixed magnet 4 are the same; the length of the floor drain inner core 5 is 60mm-70mm; the included angle between the conical surface of the conical magnet 3 and the horizontal plane is 40-50 degrees, preferably 45 degrees; the thickness of the grate 1 is 3mm-4mm, and the grate 1 is provided with strip holes with the width of 5 mm; the conical filter screen 2 is provided with uniformly distributed overflow holes, the width of each overflow hole is 5mm, and the length of each overflow hole is 20mm; the number of the overflow holes is 10-12.

As shown in fig. 2, the floor drain is kept in an unoperated state when no continuous water flow exists, preferably, the floor drain inner core is made of 304 stainless steel material, and the total length of the floor drain inner core is 60mm-70mm, so that the water seal height is not less than 50mm according to national standards. The bore diameter of the top of the inner diameter is 45mm, the angle of the diameter-changing part is 50-60 degrees, the gravity of water in the floor drain inner core and the repulsive force between the conical magnet and the fixed magnet enable the conical magnet to be tightly attached to the conical filter screen, a certain amount of water seal exists in the floor drain inner core, even if the water in the water seal is continuously evaporated to be dry, the tight attachment of the conical magnet and the filter screen can separate an underground drain pipe from being communicated with indoor air, and the phenomenon of odor reflection and the invasion of bacteria and insects are prevented. The angle of the inclined plane of the conical magnet is theta, theta is more than or equal to 40 degrees and less than or equal to 50 degrees, the sealing area is reduced when the angle is too small, the water cross section is reduced when the angle is too large, the smoothness of water flow is prevented, and the optimal angle theta is 45 degrees.

As shown in fig. 1, when the gravity of water in the floor drain inner core is smaller than the repulsive force between two like magnets, the water stays in the inner core to form a water seal; when the water in the inner core of the floor drain is dried, the rubber sealing gasket on the conical magnet is tightly attached to the filter screen at the lower part of the inner core of the floor drain due to repulsive force, so that the odor is prevented from being reversed due to the drying of the water seal. The magnetic attraction floor drain has the advantages that as the magnetic baffle and the inner core have opposite magnetism, the magnetic attraction baffle and the inner core can attract each other to cause that a plurality of impurities are adsorbed on the magnet baffle, compared with the magnet floor drain, the magnetic repulsion floor drain has no phenomenon of adsorbing impurities, and the closing is avoided. When water flows into the floor drain, the water passes through the first layer of the grate to carry out first filtration on indoor water, so that the inflow of hair and other impurities is reduced, the pressure on the filter screen is reduced, the indoor water enters the floor drain inner core and flows through the second layer of the filter screen to carry out second interception on the impurities, and as the conical base area is larger than the contact area of the round plane, and the surface of the conical magnet is provided with a layer of rubber sealing gasket, the sealing effect between the conical base area and the filter screen at the bottom of the floor drain inner core is ensured; the water flowing through the filter screen flows down along the conical magnet and flows through a circle of space except the supporting plate, the conical magnet can be fixed by the supporting plate on the floor drain shell, so that the water can stay at the central position of the floor drain under the action of the gravity of the water and the repulsive force of the fixed magnet, the floor drain shell is of a tubular structure with an open top and a hollow inside, the floor drain mounting height is 130mm-140mm, the bottom of the floor drain shell after diameter change is about 50mm-60mm, and the bottom diameter is 40mm.

When the magnetic repulsion floor drain is used, the inner core of the floor drain can be detached, and can be taken down during cleaning, so that the grate and the filter screen can be cleaned; when the conical magnet and the floor drain inner core are taken down, the surface of the fixed magnet can be cleaned, so that the floor drain is simple and convenient.
