Abstract

The utility model relates to an odor-proof floor drain, which comprises a main frame, a filtering section arranged above the main frame, a float in the main frame, and a sealing section on the lower part of the float, wherein, the float is sheathed on an inner cover of the main frame; the bevel face of a sealing gasket of the sealing section is matched with the bevel face of a water outlet of the main frame; the filtering section is positioned on the top part of the main frame; a filtering net is positioned on the main frame below a surface cover. The utility model adopting special sealing structure completely solves the problem of upwards overflowing odor and sewage of the floor drain; by adopting the double-layer filtering, the utility model avoids rubbish inflowing into the sewer. The odor-proof floor drain has the advantages of original conception, reasonable design, and ideal selection for indoor bathrooms, kitchens, bathrooms, etc.

Description

Odour-proof floor drain

The utility model belongs to a kind of odour-proof floor drain.

The hydrolock floor drain that uses mainly relies on water sealed tank to carry out water seal at present, finds that in use the water seal effect is bad, often has peculiar smell to overflow from water seal.In order to improve this structure, some formerly apply for a patent with water seal go up bowl change into have a float function go up bowl (ball), when sewage flowed into floor drain, because buoyancy of water makes the bowl come-up, sewage was discharged the back and is gone up bowl and rely on to conduct oneself with dignity to fall and form water seal once more.When sewage pressure in the sewer is big, still keep away unavoidable peculiar smell and sewage and upwards turn over, make troubles to life.

The purpose of this utility model provides and a kind ofly can thoroughly solve the odour-proof floor drain that turns on peculiar smell and the sewage.

Technical solution of the present utility model is: odour-proof floor drain comprises body frame and is arranged on the hermetic unit composition of the filtration fraction of body frame top, the float in the body frame and float bottom, float be sleeved on body frame in cover, the locating shaft top of hermetic unit is inserted in the locating hole of inner cap, sealing mat and clamp nut are fixed on the boss of locating shaft, the inclined-plane of the sealing surface of sealing mat and body frame delivery port is complementary, and the lower end of locating shaft is connected with float by link; Above-mentioned filtration fraction is positioned at the built-in fitting at body frame top, and the body frame upper end is threaded with built-in fitting, and the cover of filtration fraction and built-in fitting are hinged by steady pin, and screen pack is positioned on the body frame of cover below.

Further describe the utility model below in conjunction with accompanying drawing:

Fig. 1 is the odour-proof floor drain structural representation;

Fig. 2 is that Figure 1A-A is to view.

Wherein: 1, screw 2, cover 3, steady pin 4, screen pack 5, built-in fitting 6, sealing ring 7, body frame 8, float 9, inner cap 10, sealing ring 11, clamp nut 12, sealing mat 13, sealing locating shaft 14, link 15, body frame delivery port 16, locating hole

As shown in Figure 1, this odour-proof floor drain can adopt injection mo(u)lding, float 8 in the body frame 7 is set for the eccentric, inner cap 9 is threaded with the body frame middle part, sealing ring 10 is equipped with in the junction, float 8 is sleeved on inner cap 9 tops, locating shaft 13 tops are inserted in the locating hole 16 of inner cap, the lower end is connected with float 8 by U-shaped link 14, the junction is fixing by screw 1: sealing mat 12 and clamp nut 11 are fixed on the boss of locating shaft 13, the bevel angle scope of design of the sealing surface of sealing mat 12 and body frame delivery port 15 is the 20-45 degree, and the angle on body frame delivery port inclined-plane is than big 2～8 degree of angle of sealing mat sealing surface.

During installation built-in fitting 5 is embedded in the floor drain outlet place, mounted floor drain body is put into built-in fitting, body frame 7 upper ends are threaded with built-in fitting 5, and sealing ring 6 is equipped with in the junction.The cover 2 of floor drain filtration fraction is hinged by steady pin 3 with built-in fitting 5, and screen pack 4 is positioned on the body frame of cover below.

During use, sewage uniform leaking hole, screen pack on cover flows in the body frame, under the buoyancy of water effect, float upwards floats, the sealing mat that will seal on the locating shaft by link is pulled upwardly simultaneously, and sewage is reverse to flow into the body frame outfall through the body frame delivery port, enters drainage pipe afterwards.When sewage was reduced to certain water level in the body frame, under the effect of deadweight, float and hermetic unit together fell, and the body frame delivery port is sealed.If peculiar smell in the sewer pipe and sewage take place when overflow, clamp nut and sealing mat are subjected to downward pressure, and sealing mat is pressed on the body frame delivery port, have strengthened sealing, make peculiar smell and the sewage can't overflow.

The utility model adopts unique hermetically-sealed construction thoroughly to solve the peculiar smell of ground leak and sewage to the drawback of overflow, adopts double medium filtration, has avoided foreign material to flow into sewer, causes artificial line clogging.This odour-proof floor drain is novel, and is reasonable in design, and result of use is good, is that the ideal that indoor toilets, kitchen, bathroom etc. are located is selected.
