Deodorant water floor drain capable of being automatically opened and closed

Abstract

The invention relates to a deodorant water floor drain capable of being automatically opened and closed. The water floor drain comprises a water collecting baffle, a cylinder main body, a sealing plate, and a counter weight hammer, wherein the water collecting baffle is fixedly mounted at an upper end opening of the cylinder main body, and a circular or elliptic water outlet pipe opening formed in the lower part of the water collecting baffle is positioned in the cylinder main body; the sealing plate which rotates around a rotating shaft is arranged at the lower part of the water outlet pipe opening of the water collecting baffle; the rotating shaft is mounted on a supporting seat arranged on the outer wall of the water outlet pipe opening or a supporting seat arranged on the inner wall of the cylinder main body through a shaft sleeve; the counter weight hammer is mounted in the cylinder main body, and is connected with one end of the sealing plate through a driving member. Through the self-weight traction of the counter weight hammer, the driving member drives the sealing plate to rotate around the rotating shaft to a horizontal position so as to block the water outlet pipe opening and realize the purpose that the floor drain is sealed for deodorization; when water is collected in the water collecting baffler, the sealing plate is automatically opened, so that drainage is realized. The deodorant water floor drain has the advantages of reasonable structure, low building cost and convenience in maintenance, and has the functions of quick deodorization, blocking prevention and backwater prevention.

Description

technical field [0001] The invention relates to a drainage floor drain, in particular to a large-diameter deodorizing drainage floor drain with gravity moment balance and automatic opening and closing. Background technique [0002] We know that waterproof floor drains need to be installed in kitchens, bathrooms and other places. The floor drain drainage channel of the common inlet structure has a small cross-section, slow flow rate, and is easy to be blocked, and the shallow depth of the inlet is easy to leak odor. However, floor drains with a blocked and sealed structure also have shortcomings. The existing floor drains with blocked and sealed structures are mainly: (1) Straight-through floor drains, which are elastically closed by two pieces of molded silica gel, and the closed mouth is pushed open by the gravity of water flow. The disadvantage is that it is easy to hang impurities and make the seal not tight, and the flow rate is small. High temperature will make it def...

AI Technical Summary

Problems solved by technology

The common disadvantage is that when draining, the gasket stops horizontally near the mouth of the floor drain, and the gasket completely blocks the main drainage section of the vertical floor drain nozzle, and drains horizontally from the circular gap

(2) The water outlet is semicircular, and compared with the circular pipe cross-section outlet, the flow rate is small, the flow velocity is slow, and it is easy to block

When clogged, people often push down the residue, and it is easy to push off the sealing plate, so the life is short

(3) The shaft axis of the semicircular sealing plate is near the diameter of the circle. When it is closed, the distance between the edge near the diameter of the semicircular water outlet and the sealing plate is fixed and the distance from the axis of the shaft is very small. When it is closed, this Edges at straight warp positions are less compressed and therefore do not seal well

The length of the edge of this straight line accounts for about 39 percent of the perimeter of the semicircular water outlet, and this structure is not good for sealing
