Abstract

The utility model provides an automatic anti-blowing and anti-flow-back exhaust valve. Intakes are arranged at the top and the sides of a flow-guiding pipe, locating retainer rings are arranged at the ends of lateral intakes, the intake openings are double aperture openings in the front and at the rear which are fixed on the locating retainer rings. The section of the small aperture end is an inclination plane which is connected with an anti-flow-back wind board via a connecting shaft arranged at the upper end and the wind board is covered on the end opening of the air duct; the big aperture end of the air duct is sleeved on an ornamental ring of the flow-guiding pipe; a pressure discharge and oil dripping hole are arranged right below the flow-guiding pipe. The product solves the problems of the oil and smoke pollution and the ventilation with the prior residential kitchens and toilets, avoids oil and smoke flow-back and odor or smoke flowing effectively, has a low cost, a long service life, is anti-corrosive and convenient to install and clean, and does not flow back or leak, thereby improving the air quality in residential environment.

Description

The anti-outlet valve that pours in down a chimney of the anti-smoke blowing of automatic type

Technical field: the utility model relates to a kind of anti-outlet valve that pours in down a chimney of the anti-smoke blowing of automatic type that is installed on the air exhaust channels such as house kitchen, toilet.

Background technique: all there is flue in the kitchen in house at present, the smoke evacuation bellows of lampblack exhauster directly links to each other with the brick cigarette magnesia air exhaust channel of building, because not anti-smoke blowing backward flowing preventing device between lampblack exhauster and the building body air exhaust channel, oil smoke under the upstairs house all enters same flue, thus often occur that oil smoke pours in down a chimney, smoke blowing, taint of odour.

Summary of the invention: the purpose of this utility model is that the oil smoke that exists in house kitchen, toilet ventilation and the cooking-fume discharging pours in down a chimney in order to solve, smoke blowing, taint of odour problem, and the anti-outlet valve that pours in down a chimney of the anti-smoke blowing of a kind of automatic type that provides.

For achieving the above object, the technical solution of the utility model is: the anti-outlet valve that pours in down a chimney of the anti-smoke blowing of a kind of automatic type, comprise honeycomb duct, the mouth of pipe, vertical honeycomb duct top and side direction have ventilated port, be provided with the location snap ring at the lateral port end, fix by draw-in groove and honeycomb duct lateral port, the mouth of pipe is front and back twoport foot-path calibres, on the snap ring of location, wherein the small-caliber end cross section is the plane of inclination by screw, by the anti-barge board that pours in down a chimney of the coupling shaft connection of upper end, barge board is covered on the port of the mouth of pipe, the anti-barge board lower end of pouring in down a chimney is provided with locking counterweight transverse slat, and the heavy caliber end of the mouth of pipe is nested with the water conservancy diversion rosette, has pressure release on the tube wall under the honeycomb duct, oil dripping hole.

The utility model has solved present house kitchen and toilet oil smoke pollution and ventilating problem owing to adopt said structure.When getting rid of oil smoke, prevented effectively that oil smoke from pouring in down a chimney and smoke blowing, taint of odour problem; This product adopts engineering plastics to make, and can effectively reduce cost, and prevents to wear out, and is anticorrosive, long service life, and dismounting is cleaned convenient, and nothing refluxes not have and reveals, and has improved and improved the air quality of dwelling house living environment.

Description of drawings: Fig. 1 is a cross-sectional view of the present utility model.

Embodiment: embodiment of the present utility model is described further: the anti-outlet valve that pours in down a chimney of the anti-smoke blowing of a kind of automatic type below in conjunction with accompanying drawing, comprise honeycomb duct 6, the mouth of pipe 2, vertical honeycomb duct 6 tops and side direction have ventilated port, be provided with location snap ring 7 at the lateral port end, fix by draw-in groove and honeycomb duct lateral port, the mouth of pipe 2 is front and back twoport foot-path calibres, be fixed on the snap ring 7 of location by screw 5, wherein the small-caliber end cross section is the plane of inclination, coupling shaft 9 by the upper end connects the anti-barge board 8 that pours in down a chimney, barge board 8 is covered on the port of the mouth of pipe 2, anti-barge board 8 lower ends of pouring in down a chimney are provided with locking counterweight transverse slat 10, the heavy caliber end of the mouth of pipe 2 is nested with water conservancy diversion rosette 1, has pressure release oil dripping hole 11 on the tube wall under the honeycomb duct 6.Between the surface of contact of the location snap ring 7 and the mouth of pipe 2, be provided with ring pipe mouth sealing ring 4, mouth sealing ring 3 outside between honeycomb duct 6 and the mouth of pipe 2 surface of contact, being provided with.

At first honeycomb duct 6 vertically is arranged in the flue exit of body of wall during installation, the lateral port of honeycomb duct 6 is positioned at the smoke orifice place, at honeycomb duct 6 side mouth inward turning tightening position snap rings 7, two

seal rings

4,3 are placed between the surface of contact of honeycomb duct 6, location snap ring 7 and the mouth of pipe 2, by screw 5 mouth of pipe 2 is fixed on the snap ring 7 of location, again water conservancy diversion rosette 1 is inserted in the mouth of pipe port, promptly finish installation process.The cross section of water conservancy diversion rosette 1 is isosceles trapezoid, and is front wide and rear narrow, can effectively reduce the running resistance of oil smoke air-flow.

The smoke evacuation bellows of lampblack exhauster is enclosed within mouth of pipe outer end, and the oil smoke air-flow of discharging by the mechanical forced air draft of lampblack exhauster enters in the mouth of pipe, because the wind-force effect, barge board 8 lifts automatically, open the mouth of pipe 2 air channels, the oil smoke air-flow enters honeycomb duct 6 rapidly, enters the body of wall flue.When no oil smoke discharge advances, barge board 8 is because deadweight falls sealing orifice 2 automatically; When the oil smoke air communication of discharging is downstairs crossed the body of wall flue, flue gas passes through along honeycomb duct 6 shell arc-shaped curved surfaces, can reduce resistance, oil smoke is passed through fast, even the oil smoke discharge amount is big or when being obstructed, it is suitable for reading that flue gas enters honeycomb duct 6 in the flue, air-flow is run into the locking counterweight transverse slat 10 of barge board 8 lower ends, under the effect of air-flow, make barge board 8 be adjacent to the mouth of pipe 2 more, guarantee that the oil smoke air-flow can't pour in down a chimney.In honeycomb duct 6, form malleation, when becoming negative pressure in the flue, can natural exhaust.
