Drawings

Fig. 1 is a schematic structural view of a dual-blade fan according to the present invention.

Detailed Description

The invention will be described in further detail with reference to the accompanying drawings, which are simplified schematic drawings and only schematically illustrate the basic structure of the invention, and the direction of the present embodiment is based on the direction of fig. 1.

As shown in fig. 1, a double-blade fan includes a front mesh enclosure 1, a rear mesh enclosure 2 and a motor rear shell 3 which are connected in sequence, the front mesh enclosure 1, the rear mesh enclosure 2 and the motor rear shell 3 are connected into a cavity, the double-blade fan further includes a first fan blade 4, a second fan blade 5, a first motor 6 and a second motor 7 which are arranged in the cavity, the first fan blade 4 and the second fan blade 5 are arranged between the front mesh enclosure 1 and the rear mesh enclosure 2, the first motor 6 and the second motor 7 are arranged in the motor rear shell 3, the first fan blade 4 is connected with the first motor 6, a second shaft core 71 which is used for being connected with the second fan blade 5 is arranged on the second motor 7, and the second shaft core 71 sequentially passes through the first motor 6 and the first fan blade 4 to be connected with the second fan blade 5.

The utility model discloses a different flabellum of motor control, second motor 7 drives 5 corotation air-outs of second flabellum, first motor 6 drives 4 reversals of first flabellum and increases the intake, can adjust the different rotational speeds of first motor 6 and second motor 7 respectively, thereby adjust the wind speed amount of wind of complete machine, the rotational speed that two motors are different is adjusted, can reach the conversion of gentle breeze to strong wind, have stronger performance than traditional single fan blade fan, and another flabellum also can continue work when one of them flabellum can not work, can prevent to use the condition of fan cooling when can not in time change the maintenance like this.
