Description

One is anti-reverse returns soot device

Technical field

This utility model belongs to oil smoke and gets rid of and field of purification, relates to a kind of oil fume preventing device, specifically a kind of anti-reverse returns soot device.

Background technology

Along with social development, the urbanization gradually of increasing area, particularly in city or surrounding city all built high-storey community or apartment, the quality of life making people is more and more higher, but living in high-storey apartment, the inverse problem of returning of the oil smoke of floor smoke discharging pipe has become a great problem in people's life.Although having at present, multiple flue is anti-reverse returns device, also has on smoke exhaust ventilator and is also provided with the anti-reverse soot device that returns, but because effect is all bad, so the anti-reverse soot device that returns of twice also could not block oil smoke.When the resident in high-storey daily cook cooking time the oil smoke discharged easily from the inverse indoor returning to other residents of pipeline, bring great puzzlement to resident family.

At present, lampblack-preventing on the market is inverse returns device, is mainly turnover plate type smoke barrier, opposite opened smoke blocking board, cover-plate type smoke barrier, and drawplate type smoke barrier needs manually to pull open in use, then discharge fume, resetted by back-moving spring afterwards, carried out pipeline closed, make oil smoke inverse to return, but by long-term use, when spring force weakens, smoke barrier seal can reduce, and oil smoke can inverse from gap return；And the smoke barriers such as opposite opened need to be supported it by axostylus axostyle and rotate, rotation space can be left when mounted because of the reason of axostylus axostyle, although most pipeline space can be sealed by smoke barrier, but oil smoke still can inverse from axostylus axostyle etc. space return, cause obturation effect bad, make it still there will be the inverse problem returned of oil smoke, bring pollution to people's living environment at ordinary times.

Utility model content

The purpose of this utility model is that the one for the deficiencies in the prior art offer is anti-reverse returns soot device, cooperation by arc-shaped guide rail and soft smoke barrier, eliminate the gap between smoke barrier and housing exhaust opening, under flue wind positive pressure, exhaust opening can be carried out entirely without gap shielding, and utilize the mutual adhesive of permanent magnet being separately positioned on smoke barrier and housing, sealing and stability can be strengthened, it is effectively improved obturation effect, exhaust opening is fully sealed, efficiently solves the inverse problem returned into indoor of oil smoke.

The technical scheme that this utility model adopts:

nullOne is anti-reverse returns soot device，Including base，Base be may be installed on flue by bolt，Cooking smoke guiding plate it is provided with in base，Bootable oil smoke is upwards discharged，Base is connected with housing by bolt，In enclosure interior, exhaust opening is set，It is arranged over smoke barrier at exhaust opening place，Smoke barrier is connected with inner walls by being arranged on the arc-shaped guide rail at two ends above exhaust opening，During smoke evacuation, smoke barrier can open up along arc-shaped guide rail under the wind-force effect of lampblack absorber，Smoke evacuation is fitted along arc-shaped guide rail with exhaust opening in housing after terminating under gravity，In guide rail front, limiting card is set，Can be spacing to it when smoke barrier is opened，Smoke barrier is made to have certain angle after opening，Cannot will not fall with inner walls laminating because of after opening，Housing exterior walls at exhaust opening place and smoke barrier respectively on permanent magnet is set，The permanent magnet being arranged on housing exterior walls is mutually corresponding with the permanent magnet position being arranged on smoke barrier，Smoke barrier is made to fit with exhaust opening under the suction of permanent magnet when falling，Reach splendid obturation effect；

Described smoke barrier is made up of soft material so that it is can be tightr with exhaust opening laminating in housing under the wind positive pressure in common duct.

Described permanent magnet is provided externally with Magnet set, can prevent oil smoke from sticking on permanent magnet.

This utility model simple in construction, cost of manufacture are low, coordinated by arc-shaped guide rail and softer smoke barrier, effectively eliminate the gap of smoke barrier and exhaust opening, and utilize the permanent magnet being arranged on smoke barrier and housing to strengthen sealing, it is effectively improved obturation effect, exhaust opening is fully sealed, efficiently solves the inverse problem returned into indoor of oil smoke, there is good airproof performance, the features such as convenient are installed.

Detailed description of the invention

Below in conjunction with accompanying drawing with by embodiment, the utility model is described in further detail, but not as restriction of the present utility model.

One is anti-reverse returns soot device, including housing 1, housing 1 is connected with base 4 one end by bolt, base 4 other end is arranged on flue by bolt, exhaust opening 8 is set inside housing 1, exhaust opening 8 can be set on exhaust duct, it is arranged over smoke blocking board 6 at exhaust opening 8 place, smoke barrier 6 is made for softer material, smoke barrier 6 is connected with housing 1 inwall by being arranged on the arc-shaped guide rail 2 at two ends above exhaust opening 8, in arc-shaped guide rail 2 front, limiting card 3 is set, housing 1 outer wall at exhaust opening 8 place and smoke barrier 6 respectively on permanent magnet 7 is set, the permanent magnet being arranged on housing 1 outer wall is mutually corresponding with permanent magnet 7 position being arranged on smoke barrier, it is provided externally with Magnet set at permanent magnet, cooking smoke guiding plate it is provided with in base 4.

During running, smoke barrier can open up under the wind-force effect of smoke exhaust ventilator, and limited is blocked, making pipeline be open state and discharge oil smoke, after mist extractor terminates, smoke barrier can fall under gravity, and by the suction of permanent magnet and exhaust opening laminating in housing, reach the effect sealed.

The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the premise without departing from this utility model know-why; can also making some improvements and modifications, these improvements and modifications also should be regarded as protection domain of the present utility model.
