Abstract

The utility model relates to an air guide odor-proof device, and belongs to the technical field of the water supply and drainage, comprising an air guide device and an air guide odor-proof floor drain. The air guide device is arranged on the inspection opening of the water drainage pipe of each toilet. The air guide odor-proof floor drain is arranged on the original floor drain of the toilet. The air guide is mainly composed of a flexible air bag which is made of flexible material. The upper end of the opening of a floor drain pipe is uniformly distributed with a plurality of water flowing groove along the circumference. The edge of one end of the opening of a buckling bowl is flat. The buckling bowl is buckled on the floor drain pipe, and the edge of one end of the opening of the buckling bowl is hung up and is not contacted with the bottom of a buckling bowl groove. The interior of the water drainage pipe drains the water, and causes the gas of the interior of the pipeline to be compressed. The flexible air bag of the air guide device and the buckling bowl of the air guide odor-proof floor drain are respectively raised and lifted, the volume-increasing and pressure-reducing functions are played, the water seal of the floor drain is not damaged, the odor of the interior of the pipe is not overflowed from the floor drain, the water drainage is smooth, and the noise is reduced.

Description

Air guide odour-proof device

The air guide deodorant belong in the building give, the water discharge technology field.

Floor drain apparatus is all arranged in the washroom of building, and floor drain mainly is for getting rid of accomodation ground ponding, its outlet and gutter connection.Floor drain apparatus is absolutely necessary to washroom, room and kitchen, but present floor drain apparatus defectiveness, and promptly the stink in the gutter is easy to overflow from the ground leak, makes people's worry.The Foreign Architecture ways of addressing this issue is on the drainage pipe next door extract duct to be installed at present.Increase extract duct and can prevent gas with foreign flavor intrusion room really, reduce drainage noise, but the building funds are increased, reduced the usable floor area of some, especially those high already workers are come into operation but do not install the owned building of extract duct, want to transform that extract duct is installed is the unusual thing of difficulty.

The purpose of this utility model provides a cover can replace stack, the air guide deodorant that contains air guide device and air guide odour-proof floor drain easy for installation.

The utility model is achieved in that installs an air guide device on the inspection hole that is positioned at each washroom on the drainage pipe, an air guide odour-proof floor drain is installed at the leak place on ground, ground.The air guide device serves as main the composition with the soft air bag of being made by flexible material such as rubber or canvas cloth, soft bladder shape is made hollow cylindrical, its circumference is many telescopic fold, soft air bag one end seals an end opening, when the gutter draining causes the instantaneous increase of intraductal atmospheric pressure, the air guide device height that can rise under the pressure action that increases plays the effect that increases volume and reduce part air pressure; The air guide odour-proof floor drain comprises button bowl, floor drain pipe mouth and button bowl groove, the button bowl is made by nonmetals such as plastics, the open end edge of button bowl is concordant, the floor drain pipe mouth upper end is evenly equipped with several and crosses tank, after the button bowl was detained thereon, the unsettled button bowl bottom land that do not contact of button bowl openend was when draining causes the intraductal atmospheric pressure increase, button bowl jack-up can be come, also play the effect that increases volume reduction air pressure.The water seal that forms between air pressure unable destruction button bowl of having been degraded by air guide device and air guide odour-proof floor drain and the floor drain pipe mouth, thus foul smell can not be overflowed from the ground leak.

The utility model has substituted extract duct, can save a large amount of constructional materialss, reduces building costs, and it is very easy especially to install on the giving of old building thing, discharge pipe line.

Concrete structure of the present utility model is provided by following examples and accompanying drawing:

Fig. 1 is the schematic diagram of air guide deodorant in the washroom;

Fig. 2 is air guide device structure, assembling schematic diagram;

Fig. 3 is a floor drain pipe mouth shape schematic diagram;

Fig. 4 is an air guide odour-proof floor drain assembling schematic diagram.

The air guide deodorant is made up of air guide device 1 and air guide odour-proof floor drain 2, and air guide device 1 is installed on the inspection hole that gutter is positioned at each layer washroom by screw, and air guide odour-proof floor drain 2 is just in original floor drain position.Air guide device 1 is made up of soft air bag 3, tight loop 4, bend pipe 5, bolt 6, soft air bag 3 is by nonmetal flexible material such as rubber or canvas cloth making, the sealing of one end opening one end, soft air bag circumference is made many fold that are arranged above and below, this fold can upwards be launched when the gutter internal gas pressure strengthens, launching stroke H is 150-200mm, and air pressure just often can collapse voluntarily; The openend of soft air bag is enclosed within the small end and the fastened circle 4 of bend pipe 5 and holds tightly, terminal pad one end of bend pipe 5 is fastened on the inspection hole of gutter by bolt 6, bend pipe is 30-45 ° with the angle α that is connected card, and bend pipe terminal pad one end has a lug 12 that stretches in the gutter, puts in length H ₁Be 15-40mm, the arc length of lug 12 is 1/4～1/2 of bend pipe bores, and the trend of lug 12 is identical with the α angle; The air guide odour-proof floor drain is made up of button bowl 11, bamboo comb 10, button bowl groove 9 and floor drain pipe mouth 7, and button bowl 11 is made by nonmetals, is that an end opening one end seals, the thin walled cylindrical of hollow, and its Closed End is the plane, and the edge of its opening one end is concordant; Floor drain pipe mouth 7 is positioned at the center of button bowl groove 9, and the height h2 that its mouth of pipe stretches out button bowl bottom land is 70-90mm, is evenly distributed in 2-5 at mouth of pipe upper end edge and crosses tank 8, its groove depth 10-20mm; Button bowl 11 downward opening being buckled on the floor drain pipe mouth 7, the unsettled button bowl bottom land that do not contact of button bowl opening one end, the water seal thickness h that forms between button bowl and the floor drain pipe mouth is 40-50mm, and the opening part of button bowl groove is stamped bamboo comb 10, and button bowl top to the space between the double-edged fine-toothed comb lower plane is to buckle

Bowl stroke h1 is 20-25mm.

When the draining of upper strata resident family, the interior gas pressurized of pipeline that the draining family is following, pressure increases, under the gas pressure that strengthens, the bowl 11 of buckleing of the soft air bag 3 of air guide device and air guide odour-proof floor drain is risen high respectively and is lifted, play the increase-volume hypotensive effect, make the gas pressure intensity that acts in the water seal unlikely, can not overflow from the ground leak thereby guarantee to manage interior gas with foreign flavor to destroy water seal.When gas lifts and pushes up bamboo comb in the button bowl is managed, still remain with certain water seal height between button bowl openend and floor drain pipe mouth.Leading the effect of stretching to the lug 12 in the gutter on the device gas is to stir draining and air guide; When the draining of upper strata, water column impinges upon to be crashed on the lug 12 and forms countless slight gap, allow because the compressed gas part of draining is able to upwards discharge along gutter by these gaps, also slowed down the foul smell pressure that acts in the floor drain water seal, water seal is not gone to pot.
