Abstract
The utility model discloses a tainting odor isolator for a public flue. The tainting odor isolator comprises a barrel, an oil smoke channel and a one-way valve plate, wherein the oil smoke channel is formed in the barrel; and the two ends of the oil smoke channel is provided with an air inlet and an air outlet respectively. The tainting odor isolator is characterized in that: a diversion curved surface is formed in the barrel close to the air inlet; and the one-way valve plate is rotationally connected to the inner wall of the barrel on the mouth of the air inlet through a revolving shaft, and corresponds to the cross section of the diversion curved surface. The tainting odor isolator is designed according to aerodynamics and the lever mechanics principle, so that air current containing oil smoke passes through the air inlet and the diversion curved surface when a range hood starts working, and the one-way valve plate is pushed away to exhaust the oil smoke into the public flue; and when the range hood stops working, the one-way valve plate is automatically closed under the action of gravity, and the oil smoke channel is isolated from the public flue, so that the oil smoke in the public flue is prevented from flowing back. After the tainting odor isolator is arranged in a kitchen or a toilet, foul gas can be effectively exhausted, harmful gas in the flue is prevented from entering, and the problems of tainting odor, tainting smoke, backflow and peculiar smell are completely solved.
Description
Technical field
The utility model relates to and a kind ofly is used for public flue, prevents that oil smoke and dirty gas from pouring in down a chimney the isolator that causes taint of odour.
Background technology
High residential building is more and more now, and the pollution that kitchen, washroom smoke blowing, taint of odour cause is also more and more serious.The relevant expert points out, contains a large amount of hazardous substancess in the kitchen fume, as carbon monoxide, sulfur dioxide, oxynitrides etc.Concentration of narmful substance is higher than national regulation atmosphere indication multiple in the oil smoke: 5 times of carbon monoxide; 14 times of sulfur dioxide; 5 times of inhalable particulates; 2.4 times of carcinogenic substance third pyrene by force.The housewife suffers from the probability of lung cancer far above smoking because of being subjected to kitchen fume pollution.
The gas that the foul smell of washroom, peculiar smell are made up of hazardous substancess such as hydrogen sulfide, methyl mercaptan, ethamine is the pollution sources of family, not only stimulates human body, but also has toxicity, is detrimental to health.
Existing pipeline taint of odour spacer structures complexity, difficulty of processing height, cost are big.
Summary of the invention
In order to overcome the above-mentioned defective of existing flue isolator, the utility model provides a kind of public flue taint of odour isolator simple in structure, easy for installation, with low cost, can thoroughly solve taint of odour, smoke blowing, pour in down a chimney and the problem of peculiar smell.
A kind of public flue taint of odour isolator, comprise cylindrical shell, be located at oil smoke passage and check valve sheet in the cylindrical shell, the two ends of oil smoke passage are respectively air intake and air outlet, it is characterized in that, be provided with the water conservancy diversion curved surface near the air intake place in the cylindrical shell, check valve sheet is rotatably connected on by rotating shaft on the cylinder inboard wall of air intake oral area, and is corresponding with the cross section of water conservancy diversion curved surface.
Further, described valve block is circular, and a side periphery of facing air intake is provided with groove, is provided with in the groove and is not stained with cotton.Be provided with on the valve block and be not stained with cotton, can prevent influences the discharge of oil smoke because greasy dirt causes valve block and water conservancy diversion curved surface bonding.
Further, the air intake end of described cylindrical shell is connected with the reducing interface.
Public flue taint of odour isolator is fixedly installed in floss hole, and the reducing interface of air intake end is connected with the smoke exhaust pipe of range hood.The utility model is applicable to various model range hoods or exhaust fans such as ceiling type, side-suction type.
The utility model utilizes aerodynamics and lever machinery to learn principle and designs, and when lampblack absorber was started working, the air communication that has oil smoke was crossed air intake and water conservancy diversion curved surface, pushes check valve sheet open, and oil smoke is entered public flue; When lampblack absorber quit work, check valve sheet was closed under action of gravity automatically, and oil smoke passage and public flue is isolated, and the oil smoke in the public flue can not pour in down a chimney.
The utility model on kitchen, Toilet Installation, can get rid of dirty gas effectively, stop the interior pernicious gas of flue to enter, can thoroughly solve taint of odour, smoke blowing, pour in down a chimney and the problem of peculiar smell, improve the air quality of kitchen, washroom, keep family's room air fresh, realize real comfortable and healthy of domestic environment.
The utility model can be made with high-quality engineering plastics, can be one-body molded, and easy for installation, with low cost.
For further specifying design feature of the present utility model and effect, the utility model is further described below in conjunction with accompanying drawing.
