The range hood air outlet cover capable of assisting in the quick opening of the valve plates can assist in the opening of the valve plates under the action of air flow, can simultaneously open or close the two valve plates, can quickly open the valve plates to keep the smoothness of an air channel, can simultaneously open the two valve plates to ensure the normality of air exhaust, ensures a smoke exhaust effect of a range hood, and reduces the noise of the range hood.
Description
Technical field
The utility model relates to a kind of outlet housing of lampblack absorber, particularly relates to a kind of lampblack absorber outlet housing that can assist valve block to open fast.
Background technology
Used in the building that now family lives generally all is public flue, the oil smoke that the range hood of every household is discharged is discharged from the dwelling house top after range hood enters public flue, if the range hood air outlet is poorly sealed, will cause the user's of lower floor oil smoke in discharge process, to enter the room of upper strata resident family, perhaps when blowing hard or air pressure when low, oil smoke that upper strata resident family discharges also can occur and enter situation in the house from the exhaust outlet of the range hood of resident family of lower floor, produce between the air flue collaborate mutually, the phenomenon of smoke blowing.So general lampblack absorber all sets out fan housing at the air outlet place of lampblack absorber, valve block is set in the outlet housing, valve block is opened when lampblack absorber uses usually oil smoke is expelled to public flue, and valve block is also closed when lampblack absorber is closed, and prevents that the oil smoke in the public flue from pouring in down a chimney.Non-return valve block in the common outlet housing is the double valve sheet structure.
Contain greasy dirt in the oil smoke, lampblack absorber uses long afterwards, and greasy dirt is piled up on the valve block easily, cause adhesion between valve block and the housing, and be piled up in greasy dirt on the valve block what depend on the performance of the grease separation of oil smoke amount that lampblack absorber sucks, lampblack absorber itself, the air-out mode of blower fan system, the shape of exhaust passage, the mounting means of discharge pipe, the temperature humidity of external environment etc.So the greasy dirt that is piled up on each valve block is unequal, this has just directly caused valve block different with the adhesion degree of the housing inner ring of outlet housing, suppose the bonding degree of the bonding degree of valve block A and housing inner ring greater than valve block B and housing inner ring, after lampblack absorber starts, static pressure in valve block its outlet housing of the moment before opening is maximum, the suffered air pressure of valve block A and valve block B equates, if the valve block B less with housing inner ring bonding degree opens earlier, then the gas pressure intensity moment in the outlet housing significantly reduces, valve block A then is difficult to open again, this has just directly caused the lampblack absorber air draft not smooth, and noise increases phenomenon and occurs.So the valve block of lampblack absorber outlet housing now usually can occur owing to the oil smoke adhesion is difficult to open, unlatching is bad and two valve blocks are not the situations of opening simultaneously.
As the disclosed a kind of lampblack absorber check (non-return) valve of Chinese patent Granted publication CN202158233U, comprise valve shell and the valve block of forming by first valve block and second valve block, described first valve block and second valve block are fixed with first rotating shaft and second rotating shaft respectively, be fixedly connected with first gear and second gear on described first rotating shaft and the corresponding position of second rotating shaft, first gear and second gears engaged can be so that two valve block interlocks of valve body be to guarantee the operate as normal of lampblack absorber.Though increased the structure that can make two valve block interlocks in this structure, two valve block opening and closing simultaneously, but because the effect of valve block edge oil smoke adhesion, and gear movement needs the cause of bigger power, use the resistance of two required unlatchings of valve block long afterwards constantly to increase, thus may cause the outlet housing valve body can't open or open bad.
The Chinese patent publication number is that the prior art of CN102353083A discloses a kind of outlet housing structure, this structure is by having added permanent magnet and magnetisable material at the valve block edge, by with the adhesive of electromagnet, increase the sealing effectiveness under the closed condition, again by with the repulsion of electromagnet, assist valve block to open.But the electromagnet cost is big in this structure, complex structure, calutron damages in oil pollution environment easily, the process that valve block is opened is that two electromagnet act on two valve blocks respectively, the unlatching of auxiliary two valve blocks respectively, if open earlier with the valve block that the case bonding degree is less, then the gas pressure intensity moment in the outlet housing significantly reduces, another valve block also is difficult to open again, though present technique has increased the structure of assisting in opening valve block, but two valve blocks are not synchronous unlatching, then still exist the hidden danger that a slice valve block is not wherein opened.
