Utility model content:
The purpose of this utility model is exactly the deficiency for prior art, and provides a kind of structure improved laminar flow hood, and it can realize when laminar flow hood does not work automatically closing air inlet, thus avoids dust impurity buildups on screen pack, cause air-flow to have some setbacks.
Technology solution of the present utility model is as follows:
A kind of structure improved laminar flow hood, comprise case, case forms air inlet, screen pack to cover on air inlet and is fixed on case, the air inlet of case fixes vertical rectangular ventilating duct, one side of rectangular ventilating duct upper end forms notch, another side relative with notch on rectangular ventilating duct forms slot, one madial wall of the rectangular ventilating duct adjacent with side described in slot forms the direction recess of inclination, the two ends of direction recess are connected with notch with slot respectively, madial wall relative with direction recess on rectangular ventilating duct forms the grooving running through rectangular ventilating duct outer wall, one end of grooving is connected with notch, be plugged with cover plate in the direction recess of rectangular ventilating duct and slot, an edge forming of cover plate has tooth bar, and tooth bar is meshed with gear through the grooving of rectangular ventilating duct, and gear is fixed in the rotating shaft of motor, and motor is fixed on case by electric machine support,
The side of rectangular ventilating duct notch both sides forms journal stirrup, and the two ends of bar shaped hairbrush are fixed on journal stirrup, and the case on the downside of bar shaped hairbrush is mounted with dirt-collecting box.
The both sides of described case are fixedly connected with handle.
On described rectangular ventilating duct, the low side of direction recess is connected with notch, and the high-end of direction recess is connected with slot, the cover plate at slot place forms the slotted eye of rectangle, and the cover plate of rack bar side forms the escape groove of rectangular ventilating duct.
One sidewall of described dirt-collecting box is resisted against on the outer wall of rectangular ventilating duct, and against there being blend stop on another sidewall relative with the outer wall of rectangular ventilating duct on dirt-collecting box, blend stop is fixedly connected on case.
The beneficial effects of the utility model are:
1, it arranges automatic closing device at the air inlet of laminar flow hood, thus realizes realizing when laminar flow hood does not work automatically closing air inlet, thus avoids dust accretions to cause air-flow to have some setbacks at screen pack.
2, the automatic closing device that it adopts can also realize clearing up the dust impurity be deposited on closing device.
