Abstract

The present invention discloses a floor drain with characteristics of self-sealing, odor resistance and insect resistance, and a drainage method thereof. The floor drain comprises a floor drain body, a cover plate, a filtration screen, a filtration screen fixation screw, a water draining duct, a silica gel sealing cover, a sealing cover cage and a sealing cover fixation screw, wherein the filtration screen is fixed on the cover plate through the filtration screen fixation screw, the cover plate is connected with the floor drain body, the lower end of the water draining duct penetrates through the floor drain body, the upper end of the water draining duct is connected with the floor drain body, the silica gel sealing cover is fixed on the sealing cover cage, the lower end of the sealing cover fixation screw penetrates through the floor drain body and is matched with the threaded hole on the sealing cover cage, and the upper end of the sealing cover fixation screw contacts the top surface of the water draining duct. According to the present invention, sealing and opening of the water circuit are achieved through the self-elasticity of the silica gel sealing cover, such that the problem that non-smooth water draining generally exists in the existing water sealing type floor drain is solved, and failure of the odor resistance and insect resistance function after water seal evaporation is avoided; and the floor drain further has advantages of simple structure, low cost, easy maintenance and the like.

Description

A kind of self sealss Anti-bad-smell anti-insect floor drain and water discharge method thereof

Technical field

The present invention relates to floor drain, relate in particular to a kind of self sealss Anti-bad-smell anti-insect floor drain and water discharge method thereof.

Background technology

Floor drain is the important interface that connects sewerage system and flooring, and as the vitals of drainage system in house, its performance quality directly affects the quality of room air, to the peculiar smell between bathroom, controls extremely important.Desirable floor drain, should have the multiple functions such as drainage speed is fast, Anti-bad-smell anti-insect, anti-clogging easy to clean, back-water-proof good seal.

Existing floor drain generally adopts hydrolock structure design, and this structure is passed through at a certain amount of water of floor drain internal reservoir, thereby avoids the foul smell in sewer to distribute into indoor, but this structure causes launching stress to increase, and then has affected drainage speed.And due to the existence of sealing structure for water, cause floor drain to be very easy to be stopped up by foreign material such as hairs, back-water-proof effect is also bad.And for a long time need not, after water evaporation is dry, odor-resistant result also can disappear.And existing self-sealing type floor drain, owing to there being the mechanisms such as spring, rotating shaft, ubiquity complex structure, easily damage, locking, cause sealing and drainage to decline.Present people thirst for a kind of self sealss Anti-bad-smell anti-insect floor drain and water discharge method solves the problem in reality.

Summary of the invention

The object of the invention is to overcome the deficiencies in the prior art, a kind of self sealss Anti-bad-smell anti-insect floor drain and water discharge method thereof are provided.

A kind of self sealss Anti-bad-smell anti-insect floor drain comprises floor drain body, cover plate, screen pack, screen pack hold-down screw, lower water conduit, silica gel sealing lid, seal cover retainer, seal cover hold-down screw; Screen pack is fixing on the cover board via screen pack hold-down screw, cover plate is connected with floor drain body, lower water conduit lower end is through floor drain body, lower water conduit upper end is connected with floor drain body, silica gel sealing lid is fixed on seal cover retainer, seal cover hold-down screw lower end is passed lower water conduit and is coordinated with the screwed hole on seal cover retainer, and seal cover hold-down screw upper end contacts with lower water conduit end face.

A kind of lower water conduit bottom surface of self sealss Anti-bad-smell anti-insect floor drain is cambered surface.

Crooked under the extruding of lower water conduit after a kind of silica gel sealing lid of self sealss Anti-bad-smell anti-insect floor drain installs, and the sealing that automatically matches with the bottom surface of lower water conduit.

A water discharge method for self sealss Anti-bad-smell anti-insect floor drain, comprises the following steps:

1), when anhydrous state, lower water conduit extruding silica gel sealing lid outside, makes silica gel sealing lid elastic deformation occur and contact sealing with lower water conduit;

2), when having water to enter, silica gel sealing lid is subject to the Action of Gravity Field of water, further occur elastic deformation and and lower water conduit between produce gap, water can be discharged smoothly;

3) water drained after, silica gel sealing lid is no longer subject to the Action of Gravity Field of water, recovering step 1) state.

Screen pack of the present invention is fixing on the cover board can take off screen pack when taking off cover plate, and cleaning is convenient; Adopt the distortion of silica gel sealing lid to coordinate realization sealing, Anti-bad-smell anti-insect with the cambered surface of lower water conduit.When needs descend water, silica gel sealing lid relies on the pressure of water to produce elastic deformation, and the water yield is larger, and the gap between silica gel sealing lid and sewer pipe is larger.Under sealing state, when sewer internal pressure increases, act on the pressure that silica gel sealing covers and increase simultaneously, make silica gel sealing lid further compress lower water conduit, sealing effectiveness is enhanced, and has thoroughly solved the problem of turning one's coat.This structure is without rapid wear frame for movements such as spring, connecting axle, turnover panels, and reliable in structure is with low cost.
