Magnetic mechanical sealing floor drain core

Abstract

The invention relates to a magnetic mechanical sealing floor drain core comprising a floor drain core main body, an inner bracket and a movable door. The inner bracket is mounted in the floor drain core main body, the lower end of the inner bracket is suspended at the water outlet of the floor drain core, magnetic force action exists between the inner bracket and the movable door, and magnetic force is utilized so that the water outlet of the floor drain core is sealed by the movable door. Through the change of water flow entering the floor drain core, the magnetic mechanical sealing floor drain core is opened and closed. The magnetic mechanical sealing floor drain core has the advantages of small size, rapid switching, great drainage capacity, good sealing effect, strong self-cleaning capability, simple structure, low manufacture cost, convenience in use and maintenance, and the like.

Description

technical field [0001] The invention relates to a floor drain core, in particular to a magnetic force mechanical seal floor drain core. Background technique [0002] As an important device to remove ground water, the floor drain plays an important role in building drainage. The floor drain should have two basic functions: one is smooth drainage, which can quickly remove the accumulated water on the ground; the other is good sealing, which can effectively prevent the odor in the sewer pipe from entering the room; in addition, the floor drain should also have good self-cleaning ability. The existing floor drains are mainly divided into trap water-sealed floor drains and mechanical seal floor drains. Compared with trap water-sealed floor drains, mechanical seal floor drains have strong drainage capacity, good self-cleaning ability, and can be sealed without water, etc. Advantages, but its sealing performance is often affected by structural defects. The patent "serialized tipp...

Problems solved by technology

The existing floor drains are mainly divided into trap water-sealed floor drains and mechanical seal floor drains. Compared with trap water-sealed floor drains, mechanical seal floor drains have strong drainage capacity, good self-cleaning ability, and can be sealed without water, etc. Advantages, but its sealing performance is often affected by structural defects

The patent "serialized tipping bucket floor drain" (CN1218095C) uses the tipping bucket to seal the water outlet of the floor drain with the help of magnetic force and counterweight force. The disadvantage is that the tipping bucket occupies too much space, which makes the water outlet of the floor drain relatively smaller, and solids are easy to deposit in the tipping bucket Impurities affect the leak tightness of the floor drain when there is no water

The patent "self-styled anti-odor and anti-overflow floor drain" (CN1667212A) uses the suction force between two magnets to make the lifting shaft drive the water outlet of the self-sealing gasket to seal the floor drain. Otherwise, the lifting shaft will not be able to rise and the floor drain cannot be sealed, so the drainage resistance is relatively large; if the water volume is small, the water outlet cannot be fully opened, and the water can only seep through the gap between the self-sealing gasket and the water outlet, leaving solid impurities, thus affecting its performance. Sealing performance; the second is that the connection between the lifting shaft and the self-sealing pad is easy to catch impurities such as hair, which affects the seal between the self-sealing pad and the water outlet

The patent "flap type sewer floor drain" (CN2160688Y) is to use the counterweight to make the flap seal the water outlet of the floor drain. The disadvantage is that when the counterweight is large, the flap is not easy to open and the drainage resistance is large; when the counterweight is small, the sealing effect of the floor drain is not good ; Therefore, the drainage capacity and sealing effect are not very good
