Multifunctional airtight floor drain apparatus

Abstract

The invention relates to a multifunctional sealed floor drain device, comprising a floor drain housing and a grid floor drain cover, wherein, the floor drain housing comprises a bowl-shaped water connector with big upper part and small lower part and a straight cylinder which is arranged on a small opening end of the water connector; a sealed water drainage device is arranged inside the floor drain housing and comprises a cylindrical sealed bracket, a float cap, a float cap bracket and an elastic supporting body; the upper end of the cylindrical sealed bracket is in sealing connection with the straight cylinder of the floor drain housing at the small opening end of the bowl-shaped water connector of the floor drain housing; the float cap bracket is supported with a tray on one hanging arm, the elastic supporting body with the float cap is arranged in the center of the tray of the float cap bracket, a sleeve is arranged in the center of the float cap and is sleeved on the elastic supporting body on the float cap bracket, and the periphery at the upper end of the float cap is pressed against the lower end surface of the cylindrical sealed bracket. The multifunctional sealed floor drain device has the advantages over the prior art that: the odor removing and separating effect is good, the water discharge amount is superlarge, the phenomenon of winding does not exist, and the self-cleaning ability and the sealing ability are good and are not weakened due to the elongated use time.

Description

technical field [0001] The invention relates to building components for decoration, in particular to a multifunctional airtight floor drain device, which is applied to floor drains connected to sewer pipes in toilets, laundry rooms, kitchens, etc. of various buildings. Background technique [0002] All kinds of floor drain devices currently on the market are based on the reverse water principle; when the water stored in the floor drain dries up when not in use for a long time, this kind of floor drain will lose its anti-odor effect; these anti-odor floor drains can only be solved temporarily The problem is that if it is used for a long time, the aftertaste phenomenon still occurs. At the same time, this kind of floor drain cannot prevent the occurrence of the backflow problem. Another kind of anti-backflow floor drain has an anti-backflow hydrophobic cover through the connecting rod in the middle, but once the connecting rod is blocked by hair, cotton fabrics and other dirt,...
