Abstract
The utility model discloses a check valve of a range hood, which comprises stoppers movably connected at the position of an air outlet of a range hood body, and is characterized in that: two or more stoppers are arranged. As the two or more stoppers are arranged for shielding the air outlet of the same area, the weight of the stoppers can be reduced; therefore, the stoppers can also be pushed away in case of less oil smoke, so as to prevent the oil smoke from remaining in an exhaust system.
Description
Technical field
The utility model relates to a kind of oil absorption machine, relates in particular to a kind of check valve of range hood.
Background technique
Alternative in the market range hood kind is a feast for the eyes, a range hood on sale on the applicant's exploitation, the market, its structure, " comprise body; described body has the air sucking mouth, and the air sucking mouth connects vent systems by pipeline, described vent systems is connected with exhaust outlet ".This range hood has been able to extensive use because the air draught effect is remarkable.But in use find, after range hood is discharged oil smoke, after vent systems quits work, can produce a pressure difference, cause adverse currents such as oil smoke, pollutant with the outside.The exhaust outlet place of oil smoke is contaminated by smoke easily in addition, generally all one stench can be arranged, and this stink can be along exhaust outlet through vent systems, and in the pipeline inlet chamber.Allow operator not feel well.Other insect, harmful animals such as mouse also can not only can pollute indoor environment in the exhaust outlet inlet chamber, even also can bring pathogen, thereby influence the healthy of people.
The applicant has developed a kind of range hood that has check valve for this reason, " comprise body, described body has the air sucking mouth, and the air sucking mouth connects vent systems by pipeline; described vent systems is connected with exhaust outlet, and described body is connected with blocking blade corresponding to the exhaust outlet place.The effect of blocking blade is to form a check valve.After vent systems quit work, range hood is inner and outside can to produce a pressure difference, and external pressure promoted blocking blade and rotated this moment, and finally sealed exhaust outlet, thereby can effectively prevent the tobacco tar adverse current of discharging.Be closed owing to exhaust outlet in addition, thereby also can stop effectively in the inlet chambers such as stink, insect, mouse.But after using a period of time, find, the check valve of this range hood part that also comes with some shortcomings, main cause is, because blocking blade need block whole exhaust outlet, so the volume of blocking blade is bigger.Volume causes the weight of blocking blade heavier more greatly.Like this when the exhaust outlet air quantity hour, can not effectively blocking blade be pushed open, thereby make the part oil smoke be positioned at vent systems.
The model utility content
The purpose of this utility model is that a kind of check valve of range hood is provided at the deficiencies in the prior art, even use the very little air output of this check valve also check valve can be pushed open, thereby oil smoke is discharged fully.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
A kind of check valve of range hood comprises blocking blade, and described blocking blade is movably connected in the exhaust outlet place of oil absorption machine body, and described blocking blade is provided with more than 2 or 2.
In the technique scheme, the exhaust outlet place of described oil absorption machine body is provided with support, and blocking blade flexibly connects on the support.
In the technique scheme, described blocking blade is hinged on the support by hinge.
In the technique scheme, the outer surface of described hinge is arranged with torsion spring, and an end of described torsion spring leans on support, and the other end leans on blocking blade.
In the technique scheme, described hinge place is provided with lid.
In the technique scheme, described 2 blocking blades are respectively first blocking blade, second blocking blade, first blocking blade is hinged on the exhaust outlet place of oil absorption machine body by hinge, described first blocking blade offers through hole, second blocking blade is hinged on first blocking blade by hinge, and blocks this through hole.
The utility model compared with prior art has following beneficial effect:
1) the utility model is provided with blocking blade more than 2 or 2, and the exhaust outlet that blocks same area can make the weight saving of blocking blade, thereby less oil smoke also can be pushed blocking blade open, prevents that oil smoke is positioned at vent systems.
2) the utility model is provided with spring and can guarantees that blocking blade closing always, prevents that blocking blade when exhaust outlet does not have air-out from externally opening under the effect of power.
Description of drawings
Fig. 1 is the structural representation of range hood.
Fig. 2 is the utility model embodiment one a perspective view.
Fig. 3 is the utility model embodiment one a plan view.

Fig. 5 is the utility model embodiment three a plan view.
Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
When vent systems is worked, the air pressure of range hood inside is greater than external pressure, oil smoke is pushed blocking blade 7 open, and from exhaust outlet 10 discharges, when vent systems quits work, then form the air pressure of external pressure greater than range hood inside, this moment, external pressure promoted blocking blade 7 rotations, and finally seal exhaust outlet 10, thereby can effectively prevent the tobacco tar adverse current of discharging.Be closed owing to exhaust outlet 10 in addition, thereby also can stop effectively in the inlet chambers such as stink, insect, mouse.
The utility model so just can make the weight saving of single blocking blade 7 because blocking blade 7 is arranged to 2, thereby also can push blocking blade 7 open when less oil smoke, prevents that oil smoke is positioned at vent systems.
Embodiment two, see Fig. 4
Compare with embodiment one, difference is that described hinge 5 outer surfaces are arranged with torsion spring 9, and an end of described torsion spring 9 leans on the support 3, and the other end leans on blocking blade 7.Be provided with torsion spring 9 and can guarantee that blocking blade 7 closing always, prevent that blocking blade 7 when exhaust outlet does not have air-out from externally opening under the effect of power.
Described hinge 5 places are provided with lid 11.Be provided with lid 11 hinge 5 is blocked, prevent that hinge 5 from getting rusty, also can be so that the utility model is elegant in appearance.
Embodiment three, see Fig. 5
Compare with embodiment one, difference is, described 2 blocking blades are respectively first blocking blade 71, second blocking blade 73, first blocking blade 71 is hinged on the support 3 by hinge 51, described first blocking blade 71 offers through hole, and (through hole is blocked by second blocking blade 73, not shown), second blocking blade 73 is hinged on first blocking blade 71 by hinge 53, and blocks this through hole.
