Abstract

The utility model discloses a deodorization, inset prevention and overflow prevention floor drain which comprises a floor drain casing body (1) and a grate cover (2). The floor drain is characterized in that a buoy (3) is movably arranged above a water outlet of the floor drain, and the water outlet of the floor drain is provided with a sealing gasket (4). The floor drain has simple structure and convenient manufacture, realizes the adjustment of inflow and outflow by utilizing the gravity and the buoyancy of the buoy to obtain the effect of double sealing, has reliable sealing, and can prevent insects and overflow.

Description

A kind of deodorization, insect protected, Floor drain against counter-flow

Technical field

The utility model relates to a kind of daily living article, is specifically related to a kind of deodorization, insect protected, Floor drain against counter-flow.

Background technology

For a long time, the newly constructed house kitchen guarding return flavor be always perplexing each developer and the house-purchase resident family a difficult problem.The stink that sewer pipe returns out is not only unpleasant, has also had influence on the physical and mental health of each resident family deeply.

The SARS that spring in 2003 took place is remembered clearly, wash in a pan the big garden in Hong Kong and once broke out extensive infection incident, in the investigation of afterwards World Health Organization, the water pipe of building and foul sewer system are isolated not enough, and being considered to may be one of factor that causes SARS (Severe Acute Respiratory Syndrome) SARS spread of infection." housing construction standard " 8.2.8 clearly stipulates: arrange shower and arrange that the position of washing machine should be provided with floor drain, the water seal depth of floor drain must not be less than 50mm.When the sanitary apparatus of no trap is connected with the living drainage pipeline in the structure, must be in outfall to divide into trap, the water seal depth of trap must not be less than 50mm.But because trap need take bigger architectural space, make kitchen guarding's ceiling height be subjected to very big influence, so traditional trap can't be installed usually in shower and kitchen guarding's floor drain down-comer road in the civil engineering process, have to odour-proof floor drain be installed in fitment process and deal with problems.And common odour-proof floor drain exists shortcomings such as the fluid-tight water level is low, sealing is poor, water is volatile, easy obstruction can't really realize deodorization.So dispute takes place because the house kitchen guarding returns flavor with the developer through regular meeting in house-purchase resident family.

Except require aproll freely, the floor drain deodorization is a most critical.Floor drain on the market all has deodorant function basically now, and according to the advanced degree of deodorization principle, facility, mode, price also is not quite similar.

Divide by the deodorization mode, floor drain mainly is divided into three kinds: water odour-proof floor drain, sealing odour-proof floor drain and three anti-floor drains.

The water odour-proof floor drain is the most traditional also modal.It mainly is to utilize the seal of water to prevent distributing of peculiar smell, and in the structure of floor drain, it is curved to establish a water storage.But because cockroach is more,, the phenomenon that cockroach stings bad water storage gulf often occurs in the sewer, cause the water storage gulf to be damaged especially in south, can not water storage, corresponding floor drain also becomes a big hole, deodorization insect protected problem far from.

The sealing odour-proof floor drain is meant floating covering and adds a loam cake, and the floor drain body is airtight to prevent foul smell.The advantage of this floor drain is that outward appearance is modern fashionable, and shortcoming flip of at every turn all will bending over when being to use is cumbersome.But occurred a kind of sealed floor drain of improvement recently on the market, under loam cake spring has been housed, with foot-operated loam cake, loam cake will be upspring during use, and the time spent does not step on back again, and is more convenient relatively.

Three anti-floor drains are state-of-the-art up to now odour-proof floor drains.It has installed a little floater shot at gutter place, floor drain body lower end, dailyly utilizes hydraulic pressure and air pressure in the sewer pipe that bead is withstood, and makes itself and ground leak closed fully, thereby plays the effect of deodorization, insect protected.Its shortcoming is a complex structure, and volume is big, and component are many, and the manufacturing cost height causes the market price higher.In case stop up, handle cumbersome.

Summary of the invention

The purpose of this utility model provides a kind of deodorization, insect protected, Floor drain against counter-flow.

The technical solution adopted in the utility model: a kind of deodorization, insect protected, Floor drain against counter-flow, comprise the floor drain housing, at the housing water inlet lid of combing is set, feature is provided with floating drum in the activity above the floor drain delivery port of floor drain enclosure interior, at the floor drain delivery port sealing mat is set.Utilize the gravity of floating drum that floating drum closely is pressed on the sealing mat, floor drain and sewer pipe are separated, the water between floating drum and the shell plays sealing again simultaneously, reaches the effect of double seal, guarantees that sealing is reliable, plays the effect of deodorization insect protected.During draining, sewage flows into space between floor drain housing and floating drum by the lid of combing, and when buoyancy during greater than floating drum weight, floating drum floats, and carries out draining, and according to the difference of floor drain inflow and water yield, floating drum is regulated openings of sizes automatically, reaches the purpose that draining is not overflowed; After draining reaches to a certain degree, when buoyancy during less than floating drum weight, under the effect of gravity, floating drum sinks, combine closely with sealing mat, cut off the path of sewer pipe and floor drain, can play deodorization insect protected effect, remaining water seals again between floating drum and floor drain housing simultaneously, reaches the effect of double seal.

Deodorization provided by the utility model, insect protected, Floor drain against counter-flow are simple in structure, easily manufactured, utilize the gravity of floating drum and the adjusting that buoyancy is realized inflow, water yield, reach the effect of double seal, and sealing is reliable, deodorization insect protected anti-spill-out.

Description of drawings

Fig. 1 is a cross-sectional view of the present utility model.

Among the figure: 1, floor drain housing; 2, comb lid; 3, floating drum; 4, sealing mat.

The specific embodiment

In the structure shown in the figure, a kind of deodorization, insect protected, Floor drain against counter-flow comprise floor drain housing 1, are provided with to comb at the housing water inlet and cover 2, and feature is provided with floating drum 3 in the activity above the floor drain delivery port of floor drain enclosure interior, at the floor drain delivery port sealing mat 4 is set.During draining, sewage cover the space of 3 on 2 inflow floor drain housings 1 and floating drum by combing, when buoyancy during greater than floating drum weight, floating drum 3 floats, and carries out draining, according to the difference of floor drain inflow and water yield, floating drum is regulated openings of sizes automatically, reaches the purpose that draining is not overflowed; After draining reaches to a certain degree, when buoyancy during less than floating drum weight, under the effect of gravity, floating drum 3 sinks, combine closely with sealing mat 4, cut off the path of sewer pipe and floor drain, can play deodorization insect protected effect, remaining water seals again between floating drum and floor drain housing simultaneously, reaches the effect of double seal.

According to the design's principle, described floating drum 3 can be replaced with ball float.

Claims

1, a kind of deodorization, insect protected, Floor drain against counter-flow comprise floor drain housing [1], at the housing water inlet lid [2] of combing are set, and it is characterized in that: in the activity above the floor drain delivery port of floor drain enclosure interior floating drum [3] is set, at the floor drain delivery port sealing mat [4] is set.
