Description

Water seal type floor drain

Technical field

The present invention relates to a kind of floor drain, particularly relate to a kind of water seal type floor drain.

Background technology

Tradition water seal type floor drain (being commonly called as odour-proof floor drain), mainly include floor drain body, the filtering cover being positioned on floor drain body, The discharge opening of downcomer and water seal, water seal is buckled in above the discharge opening of downcomer as a button bowl structure, forms " U " type Water bending (or claiming trap), utilizes the water in water bending to realize sealing, to stop that sewer odor rises.Most of hydrolocks The water seal of floor drain is shallow and water shutoff amount very little, can the back foul because the factor such as time and dry weather cause water bending water dry.For Overcoming the defect of tradition water seal type floor drain, the applicant once invented the water seal type floor drain of a kind of new structure, and obtained invention specially Economic rights, invention entitled odour-proof floor drain, Patent No. 201420007141.1.It thes improvement is that: on tradition hydrolock ground A hemispherical buoyancy aid is placed on the discharge opening of leakage.When floor drain does not has water to enter, buoyancy aid is with from flumping on discharge opening, and closing is let out The mouth of a river, prevents the foul smell of sewer from ascending into indoor.When locality leaks into water, during water enters discharge opening by water bending, Buoyancy aid is up pushed away by buoyancy of water, and buoyancy aid floats, and aquiform stool can enter downcomer by discharge opening and be discharged into sewer.This structure Floor drain can effectively stop the foul smell of sewer.But there is also problems with in actual use: 1, to run into displacement big when floor drain And when continuing a large amount of draining, buoyancy aid persistently floats, space and then minimizing between buoyancy aid and water seal, and air is compressed, air pair The pressure of buoyancy aid increases, and affects buoyancy aid and floats further, causes impeded drainage.2, it is placed on discharge opening due to buoyancy aid, the most steady Determining mechanism, buoyancy aid, under flow action, fluctuates unstable, even can deviate discharge opening, affect odor-resistant result.

Summary of the invention

The technical problem to be solved is: provide the water seal type floor drain of a kind of new structure, and this floor drain can be effective Solve former patent floor drain impeded drainage and stability of floating body sex chromosome mosaicism.

The technical solution adopted in the present invention is: a kind of water seal type floor drain, including filtering cover, water seal, discharge opening and put Hemispherical buoyancy aid on discharge opening, described buoyancy aid center is provided with conduit, and a guide rod passes through conduit and is gap with conduit Coordinating, guide rod upper end is fixed in filtering cover or water seal, and buoyancy aid can move up and down along guide rod by conduit；Described conduit lower end For bell mouth shape, lower end of the guide rod has and the cone of conduit lower end horn mouth mating shapes, the conical surface of cone and conduit lower end Horn mouth coordinates in sealing.

Use technique scheme, the method have the advantages that 1, accumulation between buoyancy aid and water seal can be made Too much gas is discharged in downcomer along the gap between conduit and guide rod, effectively alleviates the pressure that buoyancy aid floats, can ensure that Displacement is big and continues buoyancy aid under a large amount of drainage situations and floats freely, and floor drain draining is smooth.2, arrange in buoyancy aid conduit with Guide rod structure, buoyancy aid moves up and down along guide rod by conduit, it is possible to achieve buoyancy aid steadily moves up and down, and does not deviates by sluicing Mouthful.

Below in conjunction with the accompanying drawings and the technology of the present invention content is described further by detailed description of the invention.

Accompanying drawing explanation

Fig. 1 is the overall structure schematic diagram of an embodiment of the present invention.

Drawing illustrates: 1. floor drain body, 2. filtering cover, 3. discharge opening, 4. buoyancy aid, 5. water seal, 6. conduit, 7. guide rod, 8. Downcomer, 9. cone, 10. water bending, 11. chamferings, 12. conical surfaces.

Detailed description of the invention

As it is shown in figure 1, the present embodiment one water seal type floor drain, including the filtering cover 2 being placed in above floor drain body 1, floor drain The discharge opening 3 of downcomer, water seal 5 and the hemispherical buoyancy aid 4 being placed on discharge opening 3, the diameter of buoyancy aid 4 is more than discharge opening 3 Bore, the deadweight of buoyancy aid should be less than flowing through water bending 10 buoyancy of water, and during to ensure that floor drain is intake, buoyancy aid can float smoothly.Floating Body 4 center is provided with conduit 6, and a guide rod 7 passes through conduit 6 and with conduit 6 in matched in clearance, and gap is used for discharging buoyancy aid and water Gas between envelope, guide rod 7 upper end is fixed on water seal 5 or filtering cover 2, and buoyancy aid 4 can move up and down along guide rod 7 by conduit 6. The present embodiment water seal is fixed on below filtering cover, and guide rod upper end is fixed in water seal, and guide rod can use spiral shell with the fixing of water seal Stricture of vagina structure is fixed.Conduit 6 lower end is bell mouth shape, and guide rod 7 lower end has and the cone 9 of conduit 6 horn mouth mating shapes, cone The conical surface 12 of body 9 coordinates in sealing with conduit lower end horn mouth.When buoyancy aid drops to discharge opening, the horn mouth of conduit should be with cone The conical surface of body fits tightly, to prevent the foul smell of sewer from rising to floor drain along the gap between buoyancy aid conduit and guide rod, and then Enter indoor.

When locality omits water in printing, when the water of entrance floor drain enters discharge opening by the water bending of water seal, buoyancy of water can make to float Body rises along guide rod, and discharge opening is opened, and aquiform stool can enter downcomer by discharge opening, and then enters sewer discharge.Work as water seal Water bending when not having water or the water surface too low, buoyancy aid drops on discharge opening because of deadweight, closes discharge opening, blocks in sewer Foul smell enter external environment condition by discharge opening.When floor drain run into inflow big and also when continuing to intake in a large number, buoyancy aid and water seal Between accumulation too much gas can be discharged in downcomer along the gap between buoyancy aid conduit and guide rod, with alleviate buoyancy aid float Pressure, make buoyancy aid and discharge opening remain unimpeded state, so that it is guaranteed that floor drain draining is smooth.

For improving further the conical surface and the bell-mouthed sealing in conduit lower end of lower end of the guide rod cone, prevent in sewer is smelly Gas enters floor drain body along the gap between conduit and guide rod, and the conical surface 12 of lower end of the guide rod cone arranges the first sealing ring.For Improving the sealing of discharge opening and buoyancy aid contact surface further, discharge opening has the chamfering 11 matched with buoyancy aid sphere, discharge opening Second sealing ring is set in chamfering 11, so that more preferably being sealed when buoyancy aid falls.Above-mentioned sealing ring can use stickup or embedding The mode such as enter to be fixed in the conical surface and chamfering.
