Preferably, drive assembly includes motor and drive gear, the motor is fixed with the installation frame in-connection, and its output is connected fixedly with drive gear, the rack has been seted up to the one end that the flashboard is close to the motor, drive gear and rack meshing cooperation.

Preferably, the cornice is inclined at an angle of 40 °.

Preferably, the number of the ventilation openings is 12.

The novel air inlet blocking device has the advantages that the novel air inlet blocking device can block and close the air inlet outside the fresh air machine in the strong wind and heavy rain weather and other conditions, the sealing performance of the gate plate can be further improved by the indoor and outdoor pressure difference, rainwater can be prevented from entering the vent hole through the cornice, the area of the vent hole is enough, the air inlet amount is sufficient, the gate plate closing mode is automatic and convenient, and the novel air inlet blocking device is beneficial to long-term use of the fresh air machine.

Detailed Description

The following detailed description of the preferred embodiments of the present invention, taken in conjunction with the accompanying drawings, will make the advantages and features of the utility model easier to understand by those skilled in the art, and thus will clearly and clearly define the scope of the utility model.

Referring to the attached drawing 1, the novel automatic outdoor air inlet air valve in the embodiment includes an installation frame 1 adapted to an outdoor air inlet of a fan:

as shown in fig. 1 and 3, be equipped with mechanism 2 that keeps out the wind on mounting bracket 1, mechanism 2 that keeps out the wind includes drive assembly 3 and flashboard 4, flashboard 4 slides with mounting bracket 1 and is connected, mounting bracket 1 is equipped with a plurality of equal spaced vents 5 with flashboard 4 department of correspondence, flashboard 4 corresponds with vent 5 size, drive assembly 3 is used for driving flashboard 4 spacing slip in each vent 5, both ends and the overlap joint setting of flashboard 4 in each vent 5, mounting bracket 1 is equipped with the eaves mouth 6 of slope in 5 departments of each vent.

As shown in fig. 2 and 3, the driving assembly 3 includes a motor 7 and a driving gear 8, the motor 7 is fixedly connected to the mounting frame 1, an output end of the motor 7 is fixedly connected to the driving gear 8, a rack 9 is disposed at one end of the shutter 4 close to the motor 7, and the driving gear 8 is engaged with the rack 9.
