Abstract
The utility model relates to a novel full-closed flue cover for preventing wind and rain, dust and winged insects. The novel full-closed flue cover for preventing wind and rain, dust and winged insects comprises a preventing cover main body and two windshield blades positioned on two sides of the preventing cover, wherein the upper ends of the windshield blades are in hinged connection with the preventing cover main body. The novel full-closed flue cover for preventing wind and rain, dust and winged insects is characterized in that a permanent magnet is fixedly arranged at the lower end of each windshield blade; and an electromagnet and an electrical control device for controlling the electromagnet to magnetize are also arranged on the preventing cover main body. According to the full-closed flue cover for preventing wind and rain, dust and winged insects disclosed by the utility model, due to the adoption of an electromagnetic structure, the capability of resisting outside wind by the movable windshield blades is greatly improved, the capabilities of products for preventing the wind and rain, dust and winged insects are improved, the service life is prolonged, and the replacement frequency is reduced. The novel full-closed flue cover for preventing wind and rain, dust and winged insects can be used for synthesizing into newly-added functions of a range hood or can be arranged in an exhaust flue at later stage, and is convenient and practical.
Description
Technical field
The utility model relates to a kind of novel totally-enclosed flue three anti-covers, is specifically related to a kind of flue weather proof, prevents dust, prevents the totally-enclosed anti-cover in the winged insect inlet chamber, belongs to the articles for daily use field.
Background technology
The anti-cover of state-of-the art flue on the market at present is merely able to windproofly, and its operation principle is, when lampblack absorber quits work, keep out the wind blade since gravity effect and sagging naturally cover air outlet, thereby play windbreak function.This anti-cover exists defective: when wind-force was big slightly, the blade that keeps out the wind above the dust cover can constantly be blown open, be closed under the wind-force effect, and the one, produce noise and disturb residents; The 2nd, when the blade that keeps out the wind is blown open by wind-force, in the inlet chambers of will taking advantage of the occasion such as wind and rain, dust, winged insect; The 3rd, owing to open frequently, can seriously reduce himself service life, increase and change frequency, because be installed in outdoorly, it is very big that it changes difficulty.
The utility model content
The utility model is at the deficiency that prior art exists, and providing a kind of can prevent cover by the totally-enclosed flue three of windproof.
The technical scheme that the utility model solves the problems of the technologies described above is as follows: a kind of novel totally-enclosed flue three anti-covers, comprise anti-cover main body, be positioned at anti-two blades that keep out the wind that cover the main body both sides, the described blade upper end of keeping out the wind is articulated and connected with anti-cover main body, it is characterized in that, the lower end of the described blade that keeps out the wind is fixed with alnico magnets, also is provided with an electromagnet on the described anti-cover main body and is used for the electrical control gear that the control electromagnet magnetizes.
Further, the iron core end positions of described electromagnet is corresponding with the position of alnico magnets after the blade closure of keeping out the wind respectively.
Further, the polarity at iron core two ends, described electromagnet energising back is identical with the contact-making surface polarity of alnico magnets on the blade that keeps out the wind respectively.
Further, described electrical control gear comprises lampblack absorber control module and magnet control unit.
Further, described magnet control unit comprises a time-delay relay that postpones to disconnect described electromagnet power supply.
The beneficial effects of the utility model are: the utility model has adopted electromagnetic structure, has promoted the active catch air blade greatly and has resisted the ability of extraneous wind-force, thereby improved the weather proof, travel fatigue of product, anti-winged insect ability, increases the service life, and reduces and changes frequency; The utility model both can synthesize the what's new of lampblack absorber, can be contained in the later stage in the exhaust uptake again, and was convenient and practical.

Wherein, 1, anti-cover main body; 2, the blade that keeps out the wind; 3, alnico magnets; 4, electromagnet; 5, electrical control gear.
The specific embodiment
Below in conjunction with accompanying drawing principle of the present utility model and feature are described, institute gives an actual example and only is used for explaining the utility model, is not for limiting scope of the present utility model.
A kind of novel totally-enclosed flue three anti-covers, comprise anti-cover main body 1, be positioned at anti-two blades 2 that keep out the wind that cover main body 1 both sides, described blade 2 upper ends of keeping out the wind are articulated and connected with anti-cover main body 1, it is characterized in that, described lower end of keeping out the wind blade 2 is fixed with alnico magnets 3, also is provided with an electromagnet 4 on the described anti-cover main body 1 and is used for the electrical control gear 5 that control electromagnet 4 magnetizes.
The iron core end positions of described electromagnet 4 is corresponding with the position of the blade 2 closed back alnico magnets 3 that keep out the wind respectively.
The polarity at iron core two ends, described electromagnet 4 energising back is identical with the contact-making surface polarity of alnico magnets 3 on the blade 2 that keeps out the wind respectively.
Described electrical control gear 5 comprises lampblack absorber control module and magnet control unit.
Described magnet control unit comprises a time-delay relay KT who postpones to disconnect described electromagnet power supply.
The course of work of the present utility model is as follows: when lampblack absorber is not worked, the alnico magnets 3 on the blade 2 of keeping out the wind can firmly be adsorbed on the two ends of electromagnet 4 iron cores, this moment, extraneous wind-force had much at one's discretion, can not blow the blade 2 that keeps out the wind open from the outside, really play the totally-enclosed effect in weather proof, dustproof, the anti-winged insect inlet chamber.
When the lampblack absorber start button is pressed: electromagnet 4 energising, two ends produce magnetic field, and polarity is just identical with the polarity of alnico magnets 3 on the blade 2 that keeps out the wind, because the magnetic field same sex is repelled each other, the blade 2 that keeps out the wind on anti-cover main body 1 both sides is pushed open by magnetic force; Lampblack absorber starts the beginning exhaust, and the wind-force that this moment, lampblack absorber work produced can be blade 2 continual the blowing open of keeping out the wind; Time-delay relay KT enters the time-delay state, and normally closed switch NC disconnects after reaching setting-up time, the working power of tripping magnet 4, and electromagnet 4 magnetic force disappear, and play energy-conservation effect, and the blade 2 that keeps out the wind can continue to stay open state under the effect of row of wind.
When the lampblack absorber start button is disconnected: row of wind disappears outside the lampblack absorber, and the blade 2 that keeps out the wind on the anti-cover main body 1 can be sagging naturally under the effect of gravity, approaches and be adsorbed on firmly the two ends of electromagnet 4, again smoke discharging pipe played the effect of sealing; The time-delay relay KT voltage of losing the job, normally closed switch NC is in normally off again, and is ready for starting next time.
The above only is preferred embodiment of the present utility model, and is in order to limit the utility model, not all within spirit of the present utility model and principle, any modification of doing, is equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
