Abstract
The utility model relates to a contrary wind preventing device of a fume exhauster, which is composed of a shell, a sealing cover of a cylinder body, a seal valve, a back flow preventing ring, an inner wall of a sealing liquid slot and sealing liquid, wherein the shell is in a cylindrical three-way shape, the front side of the cylinder body is a vertical strip opening, and a transparent plastic film is matched, bonded and fixed with the outer diameter of the outer cylinder body of the vertical strip opening; the cylinder body, a turning neck and the inner wall of the sealing liquid slot are integrated and are formed in one piece by injection moulding to form the shell; an included angle of the cylinder body and the turning neck is 45 DEG; two guiding ribs are arranged on the combining part of the cylinder body and the turning neck, both ends of each guiding rib are vertically and respectively matched, bound and fixed with the inner diameter of the combining part and form a concentric circle with the inner diameter of the cylinder body; the sealing cover of the cylinder body is in a cup cover shape, the inner diameter of the extending port of the sealing cover of the cylinder body is matched with the outer diameter of an opening of a cylinder body; the back flow preventing ring is provided with a stopping opening which is matched with the outer diameter of the inner wall of the sealing liquid slot; the inner diameter and the outer diameter of the seal valve are movably matched with the inner diameters of the back flow preventing ring and the cylinder body. Because the back flow preventing ring is provided, the utility model can prevent that the sealing liquid level is increased overflowed and flowed back to an oil returning cup. The sealing liquid is synthesized by using water and bowl washing agent, and the utility model has a lubricating function and an oil and scale removing function.
Description
Affiliated technical field
The utility model relates to the anti-reverse wind apparatus of a kind of smoke exhaust ventilator, especially is installed in the household smoke exhaust ventilator in the building.
Background technology
At present, the household smoke exhaust ventilator of selling on the market in use is prone to the deficiency of the reverse taint of odour of falling the cigarette, State Intellectual Property Office's Granted publication in 13 days December calendar year 2001 a kind of smoke exhaust seal valve, the patent No. is 01272182.4.This smoke exhaust seal valve tank is shallow, when reverse blast is big, the water surface increases, water often overflows in the refluence pumpback lampblack absorber lubricating cup, and each parts of smoke exhaust ventilator inner chamber increase wash number easily by greasy dirt, because sealing fluid is a light water, after using a period of time, the easy fouling of seal groove does not reach seal request.
Summary of the invention
Can not effectively prevent the deficiency that counter blow is poured in down a chimney in order to overcome existing smoke exhaust ventilator, the utility model provides a kind of anti-reverse wind apparatus, this device can not only stop counter blow to pour in down a chimney taint of odour, and sealing fluid adopts water and the clean synthetic sealing fluid that washes the dishes, and has lubricated and edible vegetable oil de-sludging function.
The technical scheme that its technical problem that solves the utility model adopts is, by housing, the cylindrical shell capping, seal valve, the anti-return ring, sealed liquid cell inwall and sealing fluid are formed, housing is a cylinder threeway shape, by cylindrical shell, observation window, curve, the sealed liquid cell inwall, two guiding ribs constitute, there is a vertical Tiaokou in the cylindrical shell front, transparent plastic film cooperates with vertical Tiaokou outer cylinder body external diameter and is adhesively fixed, cylindrical shell, curve, the sealed liquid cell inwall is an one, the injection moulding one-shot forming constitutes housing, and cylindrical shell and curve angle are 45 degree, two guiding ribs are in cylindrical shell and curve joint portion, two ends vertically cooperate with its internal diameter respectively and are adhesively fixed, constitute concentric circles with cylinder internal diameter, the cylindrical shell seal closure is the bowl cover shape, and it prolongs mouthful internal diameter and cooperates with cylindrical shell upper shed external diameter, anti-backflow ring has seam, its seam cooperates with sealed liquid cell inwall external diameter, and seal valve is that alms bowl is bowl-shape, and its internal diameter and external diameter and anti-backflow ring and cylinder internal diameter are movingly.
The beneficial effects of the utility model are: can guarantee the normal lampblack-pumped while, can also prevent to seal liquid level and increase and overflow in the refluence oil return cup owing to designed the anti-return ring, adopt water and the clean synthetic sealing fluid that washes the dishes, have lubricated and edible vegetable oil de-sludging function.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.

The specific embodiment:
The specific embodiment of the present utility model is, with reference to Fig. 1, Fig. 2, Fig. 3, by housing 2, cylindrical shell capping 1, seal valve 12, anti-return ring 8, sealed liquid cell inwall 11 and sealing fluid 9 are formed, housing 2 is a cylinder threeway shape, material is plastics, by cylindrical shell 2, observation window, curve 3, sealed liquid cell inwall 11, two guiding ribs 6,7 constitute, with reference to Fig. 1, there is a vertical Tiaokou in cylindrical shell 2 fronts, transparent plastic film cooperates the formation observation window that is adhesively fixed with vertical Tiaokou outer cylinder body external diameter, cylindrical shell 2, curve 3, sealed liquid cell inwall 11 is an one, the injection moulding one-shot forming constitutes housing, and cylindrical shell 2 is 45 degree with curve 3 angles, two guiding ribs 6,7 in cylindrical shell 2 and curve 3 joint portions, two ends vertically cooperate with its internal diameter respectively and are adhesively fixed, constitute concentric circles with cylindrical shell 2 internal diameters, cylindrical shell capping 1 is the bowl cover shape, it prolongs mouthful internal diameter and cooperates with cylindrical shell 2 upper shed external diameters, anti-return ring 8 has seam, its seam cooperates with sealed liquid cell inwall 11 external diameters, seal valve 12 is that alms bowl is bowl-shape, and its internal diameter and external diameter and anti-return ring 8 and cylindrical shell 2 internal diameters are movingly.
During installation, cylindrical shell 2 bottom diameters cooperate with the smoke exhaust ventilator exhanst gas outlet, and hosepipe one end exports 13 external diameters with curve 3 oil smoke on the cylindrical shell 2 and cooperates, and the other end cooperates with body of wall smokejack hole, during use, start smoke exhaust ventilator, at this moment under the air-flow effect, move to 1 of curve 3 and cylindrical shell capping on the seal valve 12, at this moment, oil smoke is discharged through anti-return ring 8 internal diameters, curve 3, exhanst gas outlet 13 by gas approach 10, and when closing smoke exhaust ventilator, seal valve 12 falls after rise to original position by self gravitation.
