Abstract

The present utility model provides a magnetic suspension drain, comprising a first connecting member and a second connecting member that are connected with each other and adapted to respective connection to a drain opening of a drain device and a drain pipe. The magnetic suspension drain further comprises a magnetic suspension inner core arranged in the first connecting member, and the magnetic suspension inner core comprises a rotary floating rod and a rotary sealing cover. The rotary floating rod is provided with a first magnet, and a repulsive second magnet is provided inside the first connecting member. The magnetic suspension inner core is configured as follows: in a sealed state, the rotary floating rod drives the rotary sealing cover to maintain sealing with a drain end of the first connecting member under the action of a repulsive force of the first magnet and the second magnet; and in a draining state, the rotary sealing cover is disengaged from the sealing with the drain end of the first connecting member under the action of water pressure and rotates along with the water flow to promote drainage. The present utility model provides a magnetic suspension inner core that utilizes magnetism to realize automatic sealing and drainage, and rotates along with the water flow during drainage to promote drainage through the rotary floating rod and the rotary sealing cover that are integrated into one whole piece.
