Abstract

The utility model relates to an automatic air door, comprising a driving motor, a control circuit, a block board. The driving motor drives the driving worm to rotate, the worm drives the turbine to rotate, and the rotation of the turbine drives a baffle to shield over or depart from the wind port. The turbine shaft, in fixed or moving mode, drives the baffle to rotate or move by the rotation of the turbine shaft or itself, so that the effect of wind port shielding by the baffle or deviation therefrom is achieved. Beneficial effect of the utility model is that the automatic air door can flexibly open or close the wind duct baffle in order to effectively preventing air ventilation between inside and outside, and solve the problem of absolute isolation between inside and outside of the duct.Therefore, wind and other objects are prevented from entering the wind duct from the wind port, and the air door is simple in construction, convenient for installation. Smoke discharging efficient canbe enhanced by over 20% by adopting the air door, and effect is more favorable by adopting a pull type electric air door, wherein no resistance exists on the wind duct block board. A turn-over type electric air door can solve the problem of incapability of using the pull type electric air door due to inadequate horizontal position thereof.

Description

Automatic electric wind door

Technical field

The utility model relates to smoke ventilator, specifically the throttle structure of smoke ventilator.

Background technique

The parts that keep out the wind of the pneumatic baffle-type structure of Chang Yong smoke ventilator in the market, when using a period of time backboard opening and closing not put in place, cause reducing smoke ventilator efficient and smoke discharging effect, the discharging flue is not closed completely separately, can make small-sized flight being, flue dust, floater and other objects by in the passage inlet chamber.

The model utility content

The purpose of this utility model provides a kind of automatic electric wind door, solves smoke ventilator air door commonly used and is not closed completely the problem that can not be hedged off from the outer world.

The purpose of this utility model is to be achieved through the following technical solutions:

A kind of automatic electric wind door comprises drive motor, control circuit, baffle plate, and described drive motor drives worm screw and rotates, and worm screw drives worm gear drive, and the rotation of turbine drives baffle plate and blocks or depart from the air port.

Further design is, the turbine shaft position is motionless, rotates by turbine shaft and drives pitman shaft to rotation, and connecting rod drives baffle plate and rotates, thereby realizes blocking or departing from the effect in air port; Perhaps

Further design is, the turbine shaft position is motionless, and turbine shaft drives a gear and rotates, and wheel and rack connects, and described tooth bar is installed on the baffle plate, and then realizes that baffle plate blocks or depart from the effect in air port; Perhaps

Further design is, but turbine shaft position move left and right, the baffle plate that the mobile drive by turbine shaft is connected with turbine shaft moves, thus the realization baffle plate blocks or departs from the effect in air port.

The beneficial effects of the utility model are that air channel barrier can be opened or close to the electric wind door flexibly automatically, effectively prevents inside and outside air ventilation, solve the inside and outside tight problem of isolating of passage, prevent that effectively general mood and other objects from entering in the air channel by the air channel, simultaneously simple in structure, easy for installation.Can improve the smoke exhaust efficiency more than 20%, drawing and pulling type MOD particularly, the air channel barrier non-resistance, effect is better.Convertible MOD can solve because of the lateral attitude not enough, can not use the effect of drawing and pulling type MOD.

Description of drawings

With embodiment the utility model is described in further detail with reference to the accompanying drawings below.

Fig. 1 is the structural drawing of automatic electric wind door;

Fig. 2 is the structural drawing of automatic electric wind door;

Fig. 3 is the structural drawing of automatic electric wind door.

Among the figure:

1, housing; 2, drive motor; 3, baffle plate; 4, worm screw; 5, turbine; 6, air port; 7, turbine shaft; 8, position limit switch; 9, gear; 10, tooth bar; 11, control circuit; 12, connecting rod.

Embodiment

As Figure 1-3, automatically the electric wind door comprises drive motor 2, control circuit 11, baffle plate 3, and described drive motor 2 drives worm screws 4 and rotates, and worm screw 4 drives turbines 5 transmissions, and the rotation of turbine 5 drives baffle plate 3 and blocks or depart from air port 6.

As shown in Figure 1, further design is, turbine shaft 7 positions are motionless, rotates drivening rod 12 axial rotation by turbine shaft 7, and connecting rod 12 drives baffle plate 3 and rotates, thereby realizes blocking or departing from the effect in air port 6; Perhaps

As shown in Figure 2, further design is, turbine shaft 7 positions are motionless, and turbine shaft 7 drives a gear 9 and rotates, and gear 9 is connected with tooth bar 10, and described tooth bar 10 is installed on the baffle plate, and then realizes that baffle plate 3 blocks or depart from the effect in air port 6; Perhaps

As shown in Figure 3, further design is, but turbine shaft 7 position move left and right, the baffle plate 3 that the mobile drive by turbine shaft 7 is connected with turbine shaft 7 moves, thus realization baffle plate 3 blocks or departs from the effect in air port 6.

The beneficial effects of the utility model are that air channel barrier can be opened or close to automatic air door flexibly, effectively Prevent inside and outside circulation of air, solve the problem of the inside and outside tight isolation of passage, effectively prevent general mood and other Object enters in the air channel by the air channel, and is simultaneously simple in structure, easy for installation. Can improve the smoke evacuation more than 20% Efficient, particularly drawing and pulling type MOD, the air channel barrier non-resistance, effect is better. Convertible MOD Can solve because of the lateral attitude not enough, can not use the effect of drawing and pulling type MOD.
