Description
Technical field
The utility model belongs to the air discharging facility field, relates to a kind of exhaust duct interface.
Background technique
In the prior art, the exhaust duct of induced draft fan, particularly the exhaust duct of the range hood in the air bells exhauster of toilet and kitchen all needs to be connected together with public ventilation channel, the no any interface that has, just the air draft mouth of pipe is inserted the reserved opening of public ventilation channel, disadvantage is a lot, and the jointing imprecision leaks out easily, if it is dark excessively that exhaust duct inserts reserved opening, influence public ventilation channel again; What have has an interface, and the shape that its effect just can the public ventilation channel reserved opening of conversion is transformed to circle by rectangular, so that the connection of exhaust duct, have with making jointing keep tight function, but all do not have the device of anti-down draught, be easy to cause room air pollution; The special purpose interface of the anti-down draught of automatic turnover type all is equipped with in the wind outlet port of only managing the kitchen range hood, the one, this interface is positioned at the inlet of exhaust duct, can not effectively stop the down draught of exhaust duct and public ventilation channel jointing to leak outside into indoor, the one, this interface is because of being connected the wind outlet port of range hood, therefore oil return is more, and easy break-down is in case damage, fail again in time to change, then can not stop down draught.
Summary of the invention
The technical problem that solves:
A kind of exhaust duct interface is provided, can overcomes the deficiencies in the prior art, can guarantee that the exhaust duct of induced draft fan and the reserved opening of public ventilation channel tightly join, can stop down draught effectively again, avoid room air pollution; Simple in structure, integrity is strong, and is easy to loading and unloading, easy care, long service life.
The technological scheme that adopts:
The exhaust duct interface has seat board 1, anti-down wind apparatus 2 and duct collar 3, it is characterized in that: being contained in the transitional storehouse 4 of anti-down wind apparatus 2 detachable property, this storehouse and seat board 1 and duct collar 3 integrals process.
Beneficial effect: can guarantee that the exhaust duct of induced draft fan and the reserved opening of public ventilation channel tightly join, can effectively stop down draught again, avoid room air pollution; Simple in structure, integrity is strong, and is easy to loading and unloading, easy care, long service life.

Embodiment
Further explanation in detail in conjunction with the accompanying drawings; Arrow is depicted as the air draft direction among the figure.
As shown in Figure 1, anti-down wind apparatus 2 has balladeur train 5 for pushing or pull out the whole assembly of transitional storehouse 4, rotating shaft 6 is housed on it, be equipped with on this axle and vent hole 7 corresponding resistance down draught plates 8, also have in the vent hole 7 and resistance down draught plate 8 corresponding holder shoulders 9, have corresponding slideway 10 on the transitional storehouse 4; Perhaps anti-down wind apparatus 2 no balladeur trains 5, being contained on the transitional storehouse 4 of rotating shaft 6 direct detachable property that resistance down draught plate 8 is housed, the interior cross section of the corresponding vent hole in resistance down draught plate 8 and the transitional storehouse 4 is corresponding, has on cross section in this with the 8 corresponding holders of resistance down draught plate and takes on 9.
As shown in Figure 1, when resistance down draught plate 8 was in closed condition, its plate face and air draft direction were the α angle, and the size at α angle needs can guarantee under the no external force effect, stop that aerofoil 86 turns to automatically counterclockwise and is in closed condition around the shaft according to himself gravitational energy, sealed type leans against on the holder shoulder 9.
Shown in Fig. 1,3 and 4, resistance down draught plate 8 be the monolithic whole formula, and tubular type hinge 11 by place, upper part wherein and rotating shaft 6 hinges are together.
As shown in Figure 5, resistance down draught plate 8 be a double-disk, promptly combines by upper and lower two, and each sheet resistance down draught plate 8 and respectively has corresponding holder to take on 9 all by the tubular type hinge 11 at its top margin position and rotating shaft 6 hinges accordingly together.
As shown in figs. 1 and 3, also has magnetic patch 12 on the holder shoulder 9, when resistance down draught plate 8 is ferrous material, under the adhesive of magnetic patch 12, help its tight closing, but must guarantee that row of wind can open the adhesive of magnetic patch automatically; Also has push-and-pull hand 14 on the balladeur train 5.
As shown in Figure 3, also have dop 13 on the balladeur train 5, push stable after putting in place to guarantee balladeur train 5.
As illustrated in fig. 1 and 2, when being used for the range hood exhaust duct, also have oil collecting hole 15 and corresponding oil box 16 on the transitional storehouse 4, all be positioned at a side, have on the transitional storehouse 4 and oil box 6 corresponding supporting position shelfs 17 near seat board 1.
When installing and using, link together by the seat board 1 reserved opening sealed type with public ventilation channel, rotating shaft 6 must be horizontal, and in order to reliably closing of resistance down draught plate 8, during air draft, resistance down draught plate 86 is rotated and opens around the shaft clockwise by closed condition.Anti-down wind apparatus 2 can take out easily and clean or maintenance.
Down draught---be meant by being blown in the public ventilation channel with indoor wind, can severe contamination user indoor air, especially smell pollution is the most responsive.
