Abstract

A no-water automatic sealing stink proof floor drain, which comprises a water sealing body, a water floating cover and a drainage grid. During no-water, the water floating cover seals water inlet in the water sealing body by own weight so as to prevent stink in sewer pipe from turning over; during with-water, the water floating cover floats up to realize drainage under the function of buoyant force of water; during water decrease or no-water, the water floating cover realizes closing again by own weight. The utility model is characterized in that the water floating cover and the drainage grid of the floor drain are separated completely; and the water floating cover floats up and down with change of water level in the water sealing body, so the water floating cover closes automatically during no-water, and the water sealing is relied during with-water, stink in the sewer pipe is in closed status all the time. The utility model avoids the shortcoming of traditional water sealing floor drain that realizes water sealing stink proof often by manual water storage due to volatilization of water. Furthermore, floor drain used in household can be updated into no-water sealing stink floor drain without damaging main body (water sealing body) by only using the water floating cover.

Description

Anhydrous self-sealing stinking-proof floor drain

Affiliated technical field

The utility model is a kind of anhydrous self-sealing stinking-proof floor drain of the connection sewer pipe that uses for the washroom in the building, kitchen.

Background technology

Be provided with in the drainage pipes such as the washroom of existing public building, residential houses and kitchen and prevent the foul smell disperser, all exist defective to some extent, influence result of use, anti-foul smell is undesirable.As present floor drain all is by the anti-foul smell of water seal, and water easily evaporates, and anhydrously in the floor drain has not just reached the purpose of anti-foul smell.Like this user have to every day retaining in the floor drain, the floor drain that water seal is shallow, time retaining more than a day guarantees water seal; Foul smell is avoided in have to covering it completely with ways such as Polypropylence Sheets of having, but unmanned just in case the water pipe phenomenon of metalling run out occurs in the daytime man, water can not flow into sewer timely from floor drain, easily cause the generation of indoor floods phenomenon.

Summary of the invention

In order to overcome the deficiency that existing floor drain exists, the utility model provides a kind of anhydrous self-sealing stinking-proof floor drain.Its anti-foul smell mode and traditional method are completely different, promptly can not lean on water seal, and odor-resistant result are good, and avoiding the people is the generation that floor drain deodorization phenomenon is safeguarded in retaining.

The technical scheme that its technical problem that solves the utility model adopts is: bowl is buckled in the water seal that is connected one with the draining double-edged fine-toothed comb on the water seal body of traditional floor drain removed, between the base water seal body and draining double-edged fine-toothed comb of floor drain, add a hollow airtight water floating head made of plastic then.When in the floor drain when anhydrous, water floating head utilization deadweight is covered in the water seal body its lower plane and is realized the sealing deodorization on the water retaining water inlet tube mouth.Fashionable as current, the water floating head overcomes deadweight by buoyancy of water, and swims on the sewage surface in the water seal body, and sewage is realized draining by flowing into sewer pipe between dash water inlet tube mouth in the water seal body and the water floating head.Simultaneously the water floating head contacts all the time with the water surface in the floor drain, the also not anti-foul smell of water seal is arranged in the drainage procedure, along with the minimizing water floating head of water in the floor drain makes its lower plane and the interior dash water inlet tube mouth place planes overlapping of water seal body and realize anhydrous self-styledly once more gradually by deadweight, really avoided the people to safeguard deodorization for retaining.The water floating head can just can be transformed into anhydrous self-sealing stinking-proof floor drain to motionless its main body of the floor drain that has used---and the manhole cover that floor drain is original is removed, changed the water floating head and can realize anhydrous self-styled purpose.

The beneficial effects of the utility model are: can reach the purpose of automatic sealing deodorization when anhydrous in floor drain, avoid the people to safeguard the generation of floor drain deodorization phenomenon for retaining; When having water to flow in the anhydrous self-sealing stinking-proof floor drain, the water floating head is opened under the buoyancy of water effect automatically, and sewage can flow into sewer pipe.

Description of drawings

Below in conjunction with accompanying drawing the utility model is further described.

Fig. 1 is the longitudinal sectional view of the utility model anhydrous state concrete structure.

Fig. 2 is the longitudinal sectional view that the utility model has the structure of water state.

The specific embodiment

Among Fig. 1 anhydrous self-sealing stinking-proof floor drain by water seal body (3) and on water floating head (1) and (2) three of draining double-edged fine-toothed combs part form.And water floating head (1) and draining double-edged fine-toothed comb (2) are intact breaks away from, and water floating head (1) is a hollow airtight water buoyancy aid made of plastic, and its utilizes deadweight that water inlet plane (5) is overlapped and plays the sealing deodorization.

Fig. 2 is when water is arranged, and water floating head (1) is to be variable condition (6).Water floating head this moment (1) is upwards floated by buoyancy of water, and water water inlet (5) from the interior dash pipe of water seal body (3) flows into the sewer pipe.Reduce or when reaching anhydrous, the water floating head is got back to the state (7) of figure (1) again as water.

Claims

1, a kind of anhydrous self-sealing stinking-proof floor drain that is used for connection sewer pipes such as building washroom, kitchen, it comprise water seal body (3) and on draining double-edged fine-toothed comb (2), it is characterized in that between water seal body and draining double-edged fine-toothed comb, adding a hollow airtight water floating head (1) made of plastic.

2, anhydrous self-sealing stinking-proof floor drain according to claim 1 is characterized in that water floating head (1) changes up and down with the sewage surface that flows into and fluctuates and draining double-edged fine-toothed comb (2) breaks away from fully in water seal body (3).
