detailed description

The utility model is described further in conjunction with accompanying drawing now. These drawings are simplified schematic diagrams only to illustrate the basic structure of the utility model in a schematic way, so they only show the configurations related to the utility model.

As shown in Figures 1 to 3, an electric shutter fan includes a casing 1, in which a motor chamber, an air inlet chamber and an air outlet chamber are formed, and the air inlet chamber and the air outlet chamber are respectively located on both sides of the motor chamber , the main motor 5 is arranged in the motor chamber, the fan blade 6 is arranged in the air inlet chamber, the fan blade 6 is connected with the main motor 5, the filter assembly is arranged in the air outlet chamber, and the fixing frame for fixing the filter assembly is arranged on the air outlet chamber Frame 4: The filter assembly includes air filter cotton 2 and two first stainless steel mesh sheets 3, and the air filter cotton 2 is sandwiched between the two first stainless steel mesh sheets 3.

The air inlet chamber is provided with an air inlet cover 7, the air inlet cover 7 is provided with an air inlet, and the air inlet is provided with a number of louvers 8, and each louver 8 forms a rotation with the air inlet hood 7 on both sides of the air inlet respectively. connected, each louver 8 rotates up and down, the inner side of the air intake cover 7 is provided with a connecting rod 9 and a push-pull motor 10, the connecting rod 9 is respectively connected to the rotating shaft of each louver 8, and the up and down movement of the connecting rod 9 drives each louver 8 to do Turn up and down, the push-pull motor 10 is fixedly arranged in the air inlet cavity, the push-pull motor 10 is connected with the connecting rod 9, and the push-pull motor 10 drives the connecting rod 9 to move up and down.

The rotating shaft on one side of the louver 8 used to connect with the connecting rod 9 has a zigzag bend. After being connected with the connecting rod 9 , the up and down movement of the connecting rod 9 can realize the upside down turning of the louver 8 .

The casing 1 is also provided with a controller and a backup power supply, the push-pull motor 10 is connected to the controller, and the push-pull connection is connected to the backup power supply.
