The utility model discloses the part is less, simple to operate, cost are lower, only props to keep off the cigarette apron and goes out the oil smoke by the wind-force of lampblack absorber, relies on simultaneously when the lampblack absorber is out of work to keep off the cigarette apron dead weight closure and blocks the oil smoke that other resident family produced in the flue, does not need complicated mechanical parts, has avoided the problem that the installation that current extension spring formula air door exists is inconvenient, easily breaks down.
Description
Technical Field
The utility model relates to a smoke ventilator annex technical field especially relates to a novel smoke ventilator air door.
Background
The connection between existing fume exhauster and spiral flue (hose) is equipped with one-way air door to prevent fume in public exhaust flue from back-flowing into kitchen.
The existing air door is fixed by a spring, when the range hood works, the air door is blown open by wind power to discharge oil smoke, and after the range hood stops working, the spring arranged on the air door rebounds to close the air door. The disadvantages are that: 1. the spring is damaged due to the long-term open-close work of the spring; 2. the spring sticky oil smoke loses elasticity due to the severe working environment; 3. the spring needs more manual operation when being installed and assembled.
SUMMERY OF THE UTILITY MODEL
In view of the above-mentioned defect of prior art, the utility model aims to solve the technical problem that a novel smoke ventilator air door is provided to solve the not enough of current extension spring formula smoke ventilator air door.
In order to achieve the purpose, the utility model provides a novel smoke ventilator air door, include air door main part, air door mount pad, keep off cigarette apron, a word pivot, buckle, the air door main part back sets up the air door mount pad, air door mount pad upper portion sets up the buckle, install a word pivot in the buckle, keep off cigarette apron upper portion and install in a word pivot.
Further, an arc-shaped mounting groove is formed in the middle of the buckle.
Further, the opening distance of the arc-shaped mounting groove is smaller than the diameter of the linear rotating shaft.
Furthermore, the buckle is made of elastic materials.
Further, when the smoke blocking cover plate is closed, an included angle between the smoke blocking cover plate and the vertical direction is 5-58 degrees.
The utility model has the advantages that:
the utility model discloses the part is less, simple to operate, cost are lower, only props to keep off the cigarette apron and goes out the oil smoke by the wind-force of lampblack absorber, relies on simultaneously when the lampblack absorber is out of work to keep off the cigarette apron dead weight closure and blocks the oil smoke that other resident family produced in the flue, does not need complicated mechanical parts, has avoided the problem that the installation that current extension spring formula air door exists is inconvenient, easily breaks down.
The conception, the specific structure and the technical effects of the present invention will be further described with reference to the accompanying drawings, so as to fully understand the objects, the features and the effects of the present invention.
Drawings
Fig. 1 is a schematic view of the rear view structure of the present invention.
Fig. 2 is a schematic side view of the damper of the present invention when opened.
Fig. 3 is an enlarged view of the fastener and the linear rotating shaft of the present invention.
Fig. 4 is a side view of the buckle of the present invention.
Detailed Description
As shown in fig. 1-4, a novel smoke exhaust ventilator air door comprises an air door main body 1, an air door mounting seat 2, a smoke blocking cover plate 3, a linear rotating shaft 4 and a buckle 5, wherein the air door mounting seat 2 is arranged on the back surface of the air door main body 1, the buckle 5 is arranged on the upper portion of the air door mounting seat 2, the linear rotating shaft 4 is installed in the buckle 5, and the upper portion of the smoke blocking cover plate 3 is installed on the linear rotating shaft 4.
Wherein, set up arc mounting groove 51 in the middle of buckle 5, arc mounting groove 51 opening distance is less than a word pivot 4 diameters, and a word pivot 4 snap-in installs just can not run out inside arc mounting groove 51 like this. The buckle 5 is made of elastic materials, so that the linear rotating shaft 4 can be conveniently installed in the arc-shaped installation groove 51 in a clamping mode. When the smoke blocking cover plate 3 is closed, an included angle between the smoke blocking cover plate 3 and the vertical direction is 5-58 degrees, so that when the range hood works, the smoke blocking cover plate 3 can be easily opened by sucked wind power. When the range hood stops working, the smoke blocking cover plate 3 is opened due to no air suction and no wind power, and the smoke blocking cover plate 3 is closed by the dead weight to block the oil smoke generated by other residents in the flue.
The foregoing has described in detail preferred embodiments of the present invention. It should be understood that numerous modifications and variations can be devised by those skilled in the art in light of the present teachings without departing from the inventive concepts. Therefore, the technical solutions that can be obtained by a person skilled in the art through logic analysis, reasoning or limited experiments based on the prior art according to the concepts of the present invention should be within the scope of protection defined by the claims.
