Abstract
The utility model is composed of two parts, namely a valve soft cap and a valve sleeve, wherein a frame structure made of rigid materials like plastic or metal etc is arranged around the valve soft cap; the hollow portion enclosed by the frame structure is filled by soft and compact fabrics fixed on the frame structure; the internal diameter of the frame structure is several millimeters larger than the diameter of the valve; the valve sleeve is connected with one side of the frame structure of the valve soft cap through a hinge-like structure; a spring is arranged on the outer side of the hinge-like structure of the valve, and a pressure spring baffle plate is arranged on the outer side of the hinge-like structure of the valve soft cap; the included angle between the surface of the valve opening and the horizontal plane is 5 to 40 degrees.
Description
The utility model is a kind of parts and supporting use of lampblack absorber of family kitchen electrical equipment, is anti-backflow smoke soft cap valve for fume exhauster.
Resident in the building generally is that a common gas flue is passed through in the Duo Jia kitchen, discharges oil smoke outdoor.Use the smoke exhaust user who does not prevent the return of smoke and smell device, kitchen return of smoke and smell situation often takes place, this is promptly unhygienic, impairs the healthy of people again.At present, smoke exhaust for kitchen use generally adopts two anti-down cigarette devices of semilune baffle-type.There is following shortcoming in this device: this baffle plate bad sealing is close, still can self catcher sheet separation return of smoke and smell.And the cooker hood for back fume automatic electromagnetic valve (patent No.: 94224657.9) have following shortcoming: the production cost height, volume is big and be not easy to install, and has noise to produce during use.
The utility model designs for the above-mentioned shortcoming that solves the existence of two anti-down cigarette devices of semilune baffle-type and cooker hood for back fume automatic electromagnetic valve.
The utility model technical solution: the utility model is made up of the soft lid of valve and valve sleeve two parts.The periphery of the soft lid of valve is to make frame structure with hard materials such as plastics or metals.The hollow that this frame structure is surrounded partly is made of the fabric that is fixed on the soft densification on the frame structure (as rainproof nylon cloth).The internal diameter of frame structure is greater than the some millimeters of valve port external diameter.One side of the frame structure of the soft lid of valve connects together by hinge spline structure and valve sleeve.In the outside design of valve sleeve hinge spline structure spring is arranged, cover page spline structure outside design stage clip baffle plate is arranged in that valve is soft.Framework hinge spline structure one end to body side frame on fix some gram counterweights.Be 5～40 degree angles between the plane of valve port and the horizontal plane, position, hinge spline structure side valve doorway is minimum.
Adopt the utility model to do the anti-down cigarette device of smoke exhaust, obtain following good effect: the feltwork fabric that the soft lid of valve is soft, fine and close more after the oil immersion, promptly can not be permeable, can not breathe freely.The fabric that this layer is soft covers on hard valve port, and covering very tight promptly cigarette can not take place down, can not return the flavor situation yet.Valve port has certain gradient, under the blowing of smoke exhaust air draft, is very easy to open the soft lid of valve.The soft lid of valve is opened to a certain degree, and spring bearer plate just in time is pressed on the spring, can hinder the soft lid of valve and excessively open; After smoke exhaust cut out, under the spring force effect, the soft lid of valve can be closed immediately, thereby the soft lid of valve can not take place closed malfunctioning situation.This utility model production cost is low, and volume is little, is convenient to noiselessness during work is installed.
Brief Description Of Drawings: figure one is the soft lid of the utility model valve structural representation when opening; Structural representation when figure two closes for the soft lid of the utility model valve; Figure three is the vertical view of figure two.
Accompanying drawings the utility model embodiment: the valve inlet 1 of valve sleeve 10 is installed in the smoke exhaust outlet.Soft fibre fabric 11 is fixed in the soft cover frame shelf structure 9 of valve, and soft cover frame shelf structure 9 of valve and valve be soft to cover leaf moving part 7 and spring bearer plate 6 is connected as a single entity.By hinge axis 8 hinge moving part 7 and hinge being decided part 4 connects together.Hinge is decided part 4 and valve sleeve is fixed together with set bolt 3.Spring 5 is fixed on hinge decides part 4 outsides.Valve export 12 and the smoke pipe that leads to flue join.
When opening smoke exhaust, oil smoke arrives valve port 2 by valve inlet 1, and the soft lid of valve is blown open, and when the soft lid of valve is opened to a certain degree, spring bearer plate 6 promptly has been pressed on the spring 5, has prevented that promptly the soft lid of valve from excessively opening.Oil smoke enters flue through valve export 12.After closing smoke exhaust, under spring 5 elastic force effects, the soft lid of valve is closed, and under counterweight 13 effects, the soft lid of valve contacts tightlyer with valve port 2.
