In order to improve the suction oil smoke of range hood or the effect of suction harmful gass, the most direct means are to increase oil suction
The air quantity of cigarette machine, the more big caused noise of air quantity is inevitable bigger, and excessive noise can affect people to using range hood
Body-sensing, also may can damage the hearing system of human body when serious.
Content of the invention
The purpose of this utility model is to overcome the shortcomings of that above-mentioned prior art exists, and provides a kind of used for range hood
Noise elimination structure, when it can be greatly lowered range hood work, produced noise is it is ensured that the use body-sensing of user is good, it is to avoid
Excessive noise can insulting hearing system.
The purpose of this utility model is realized in：
A kind of noise elimination structure used for range hood, including the noise elimination main body being arranged on air outlet for kitchen ventilator, its structure
It is characterised by, noise elimination main body is in hollow tubular, is coaxially provided with a noise elimination bobbin, has between noise elimination main body and noise elimination bobbin inside it
Space simultaneously forms the second noise elimination cavity；Noise elimination barrel inner is provided with noise elimination dividing plate, and noise elimination dividing plate is separated into noise elimination bobbin and goes to upper and lower
3rd noise elimination cavity of setting and the first noise elimination cavity, three noise elimination cavities are interconnected.
Described silencing pot pipe surface is covered with noise elimination air-vent.
Described 3rd noise elimination cavity and the deep equality of the first noise elimination cavity.
The depth of described 3rd noise elimination cavity is less than or greater than the depth of the first noise elimination cavity.
It is provided with sealing structure between described noise elimination main body and air outlet for kitchen ventilator.
Described noise elimination bobbin is an overall long tube, and noise elimination dividing plate is arranged on inside it, or, noise elimination bobbin is by two long tubes
Constitute, be separately fixed at the opposite sides of noise elimination dividing plate.
Described noise elimination main body is made of metal.
Described noise elimination bobbin is made of metal, or is made up of deadener.
The beneficial effects of the utility model are as follows：
Noise elimination structure of the present utility model is to be directly installed on air outlet for kitchen ventilator, Assembly part that need not be too many,
And installation step, low cost of manufacture, later stage installation easy maintenance；It can be greatly lowered produced during range hood work
Noise is it is ensured that the use body-sensing of user is good, it is to avoid excessive noise can insulting hearing system.
Brief description
Fig. 1 is the exploded view of this utility model one embodiment.
Fig. 2 is the installation diagram of this utility model one embodiment（Section view）.
Specific embodiment
Below in conjunction with the accompanying drawings and embodiment is further described to this utility model.
Referring to Fig. 1-Fig. 2, this noise elimination structure used for range hood, including the noise elimination master being arranged on air outlet for kitchen ventilator
Body 1, noise elimination main body 1 is in hollow tubular, is coaxially provided with a noise elimination bobbin 2, has between noise elimination main body 1 and noise elimination bobbin 2 inside it
Space simultaneously forms the second noise elimination cavity 12；It is provided with noise elimination dividing plate 3,3 noise elimination bobbins 2 of noise elimination dividing plate are separated into inside noise elimination bobbin 2
Go to upper and lower the 3rd noise elimination cavity 13 and first noise elimination cavity 11 of setting, three noise elimination cavities are interconnected.Air outlet for kitchen ventilator air draft
When, air-flow enters from the first noise elimination cavity 11, then flows into the second noise elimination cavity 12 under the secondary retention of noise elimination dividing plate 3, then from
Three noise elimination cavity 13 discharges noise elimination main body 1, and through the effect of three noise elimination cavities, air draft air-flow can be eliminated most noise,
The operating noise of range hood is enable to be substantially reduced.In addition, noise elimination dividing plate 3 can separate exhaust duct and oil suction naturally
The air vent of cigarette machine, can play certain isolation external influence, play the effect of certain insect protected, anti-backflow.
Further, noise elimination bobbin 2 surface is covered with noise elimination air-vent 21, the pore size as noise elimination air-vent 21 and
Its punching rate, can be according to actual design.
Further, the deep equality of the 3rd noise elimination cavity 13 and the first noise elimination cavity 11, or, the depth of the 3rd noise elimination cavity 13
Depth less than or greater than the first noise elimination cavity 11.The present embodiment adopts the technical scheme of deep equality, and through out-of-date, the 3rd disappears air-flow
The capacity of the operatic tunes 13 is equal with the air inflow of the first noise elimination cavity 11.In the same manner, according to the unequal technical scheme of depth, can make
The capacity of the 3rd noise elimination cavity 13 is unequal with the air inflow of the first noise elimination cavity 11, and these technical schemes are also according to actual design
From.
Further, sealing structure 14 can be provided between noise elimination main body 1 and air outlet for kitchen ventilator, to ensure to leak
Wind, the preferred sealing ring of sealing structure 14.
Further, noise elimination bobbin 2 is an overall long tube, and noise elimination dividing plate 3 is arranged on inside it, and processing cost is relatively more
Low, or, noise elimination bobbin 2 is made up of two long tubes, is separately fixed at the opposite sides of noise elimination dividing plate 3, and assembling is easier, this
The preferably previous technical scheme of embodiment.
Further, noise elimination main body 1 is made of metal, and durability is higher.
Further, noise elimination bobbin 2 is made of metal, and durability is higher；Or it is made up of deadener, soundproof effect is more
