[specific embodiment]
Below in conjunction with accompanying drawing the utility model is described in further detail.
The first embodiment: referring to accompanying drawing 1, Fig. 2, shown in Figure 3, the present embodiment comprises casing 1, and the air inlet 2 that is positioned at casing 1 front portion, flue gas enters the smoke collecting chamber of oil extracting machine from air inlet 2, then discharge outdoor, also comprise drop front device 3, drop front device 3 can be installed on the front part sides limit of casing 1 and be symmetrical arranged, described drop front device 3 comprises drop front 4 and the hinge 5 that is hinged with casing 1 top, drop front 4 is realized folding take described hinge 5 as rotating shaft with respect to air inlet 2, sets the folding stroke of described drop front 4 by position-limit mechanism 6.
Wherein, described position-limit mechanism 6 comprise the outer triangle 7 of plastics and the plastics that match with outer triangle 7 size shape of plastics in triangle 8, the outer triangle 7 of described plastics is provided with the cavity volume that embeds triangle 8 in the plastics.Triangle 8 middle parts are provided with stopper slot 9 in the described plastics, and outer triangle 7 middle parts of plastics are provided with the limit rib 10 suitable with stopper slot 9.In the described plastics triangle 8 be built-in with plastics in the snap-on fixture 11 that is spirally connected of triangle 8, snap-on fixture 11 fixing springs 12, an end peripheral hardware snap close 13 of spring 12.Described air inlet 2 places also be provided with screen pack 14 and with the suitable sliding screen 15 of screen pack 14, sliding screen 15 is positioned at screen pack 14 both sides.
In the present embodiment, the opening angle of described drop front 4 can for 5 the degree to 80 the degree, concrete angle is not done special restriction, with the shape of triangle 8 in the outer triangle 7 of the plastics of position-limit mechanism 6 and the plastics, the size that size is determined opening angle, but preferably just can open 10 degree to the scope between 45 degree, be more conducive to collect flue gas under the range hood work.
