Abstract
The invention relates to a range hood terminal air outlet by which an air door of range hood which is not used for a long time and pasted by oil sludge can be pushed open smoothly. The range hood terminal air outlet consists of a shell, a diaphragm, a middle beam, a tension spring, single-sheet or dual-sheet butterfly plates, levers and a seal line, wherein the tubular shell is internally provided with the middle beam and the seal line; two butterfly plates with hollow middle parts are symmetrically articulated at the left side and the right side of the middle beam; the elastic diaphragm is embedded on the hollow parts; the rear sides of the butterfly plates are provided with the levers; the end parts of the short arms of the levers are provided with contacts which are in contact with supporting points on the inner wall of the shell; the diaphragm moves toward the back side when being pushed by air force to push the long arms of the levers to move outward along the air direction; and the short arms of the lever press the supporting points to generate a reverse push force, and the edges of the butterfly plates are separated from the seal line, thus the butterfly plates are rotated, and the air door is opened; and because the edges of the butterfly sheets are provided with two pairs of fan-shaped gears, any butterfly plate rotates, and the other butterfly plate is driven to rotate together, thus the oil fume can be exhausted smoothly. The other form is that a single butterfly plate is adopted, and the operation principle and the effects of the single butterfly plate are the same with those of the double butterfly plates.
Description
Technical field
The present invention relates to the field of accessories of cooking-fume exhauster, specifically refer to a kind of smoke exhaust ventilator terminal air outlet of air.
Background technology
Smoke exhaust ventilator is the requisite cleaning equipment of modern kitchen, and it and gas-cooker, disinfection cupboard are described as " three-major-items " of modern kitchen.Usually smoke exhaust ventilator before dispatching from the factory all the air outlet at the cabinet top butterfly non-return wind door that flue gas is refunded is housed, and the user has also installed non-return wind door in the smoke exhaust pipe exit, and its main purpose is for preventing extraneous strong wind or entering from neighbours's smoke exhaust ventilator cooking fume out that common flue rises that oneself is indoor.This class non-return wind door normally arranges two baffle plates of butterfly in shell, be installed in the outside of non-return circle, when oneself smoke exhaust ventilator was started shooting outside exhausting oil fume, two baffle plates were blown open, cooking fume can be expelled to outdoor by air outlet swimmingly or common flue in.And when the cooking fume of neighbours in extraneous strong wind or the common flue entered, two baffle plates were covered air outlet, and extraneous strong wind or cooking fume are blocked in outside the exhaust duct, made extraneous oil smoke can not enter oneself kitchen and caused " taint of odour ".So the butterfly non-return wind door of air outlet is absolutely necessary.But people in actual use, butterfly throttle can not in time be opened after finding sometimes smoke exhaust ventilator start, especially after long-term the use because going out or other reasons a period of time is not enabled smoke exhaust ventilator, dry and hard greasy filth especially as " adhesive sticker " the butterfly plate of non-return wind door and non-return circle stick fast, smoke evacuation is had some setbacks, affect the normal use of smoke exhaust ventilator.This phenomenon has almost become the common fault of the sector smoke exhaust ventilator product.Till settled the present, do not have also to prevent that strong wind pours in down a chimney or extraneous cooking fume is invaded, and the smoke exhaust ventilator terminal air outlet of air door generation that can be easy to open, this device designs in order to fill up this vacancy.
Summary of the invention
The objective of the invention is: overcome existing air outlet of smoke exhauster butterfly throttle plate was easily clung and opened difficulty by greasy filth defective, the blast that utilizes the smoke exhaust ventilator air channel to blow out can be opened the smoke exhaust ventilator terminal air outlet of air of air door plate automatically.
The technical scheme of technical solution problem of the present invention is, a kind of smoke exhaust ventilator terminal air outlet of air, by housing, barrier film, central sill, extension spring, butterfly plate, lever and potted line form, described housing in a tubular form, be arranged with mounting flange outward, described inner walls is provided with potted line, described central sill is arranged on the diametrical position at housing bore seal line center, symmetrical hinged two butterfly plates in the described central sill left and right sides, fit with the potted line that is located in the housing in the butterfly plate edge, transmission in the middle of the described butterfly plate, the elastic diaphragm of transmission place setting-in oil resistant is that the front is provided with extension spring in the windward side of described barrier film.The described butterfly plate back side that facings the wind is that reverse side is provided with lever, be provided with pivot pin in the described lever, pivot pin becomes to be actively coupled with the axle bed that is located at the butterfly plate edge, and lever is divided into galianconism and long-armed, described long-armedly contact with the reverse side of barrier film, the contact is established in the end of described galianconism, and the tip of contact contacts with the fulcrum that is located at inner walls.When described barrier film wind-engaging is tried hard to recommend the trend back side and heaved, promote the long-armed down wind of lever mobile outward, the moment of the long-armed generation of lever, drive galianconism and make pressure to the fulcrum that is located at the inner walls edge, produce propulsive thrust, the butterfly plate edge is separated with potted line, butterfly plate namely is open.
The another kind of form of a kind of smoke exhaust ventilator terminal air outlet of air is to adopt the monolithic butterfly plate, formed by housing, barrier film, extension spring, butterfly plate, lever and potted line, transmission in the middle of the described butterfly plate, the elastic diaphragm of transmission place setting-in oil resistant, be that the front is provided with extension spring in described barrier film windward side, the butterfly plate back side that facings the wind is that reverse side is provided with lever.Be provided with pivot pin in the lever, pivot pin be located at butterfly plate edge axle bed and become to be actively coupled, and lever is divided into galianconism and long-armed, described long-armedly contact with the reverse side of barrier film, the contact is established in the end of described galianconism, the tip of contact contacts with the fulcrum that is located at inner walls.When described barrier film wind-engaging is tried hard to recommend the trend back side and heaved, promote the long-armed down wind of lever mobile outward, the moment of the long-armed generation of lever, drive galianconism and make pressure to the fulcrum that is located at the inner walls edge, produce propulsive thrust, the butterfly plate edge is separated with potted line, butterfly plate namely is open.
Two hinged butterfly plates of described and central sill are respectively equipped with the sector gear centered by central sill at two ends, two pairs of gear symmetries are intermeshed, and do synchronously the fan-shaped rotation so all can drive another piece butterfly plate when arbitrary butterfly plate rotates.
Described barrier film front is provided with a narrow meshed tappet, and an end hook of extension spring is in the aperture of tappet.The other end of extension spring is connected with the inwall of central sill or housing.
What the present invention was useful is: during cooking fume blow pressure that barrier film is discharged in by flue, outwards heave, produce thrust, promote the long-armed generation moment of lever, make the crotch of lever short arm end press to fulcrum, produce propulsive thrust and prize the butterfly plate edge and separate with potted line, even dry and hard greasy filth viscosity is large again, butterfly plate is rotated, and owing to being provided with two pairs of intermeshing gears in the central sill, so arbitrary butterfly plate rotates, all can driving another piece butterfly plate and rotate together, air door all can be opened automatically, makes the smooth and easy discharge of cooking fume energy.
