Detailed Description
The principles and features of the present invention are described below with reference to the drawings, the examples are illustrated for the purpose of illustrating the invention and are not to be construed as limiting the scope of the invention.
Referring to fig. 1-6, as shown in the drawings, the building ventilation device provided in this embodiment includes a ventilation pipe 1 and a fan 3, the fan 3 is fixedly connected to the ventilation pipe 1 through a support rod 2, a fan blade is fixedly connected to an output shaft on the fan 3, a filter screen 9 is disposed at an opening of the ventilation pipe 1, a cleaning member 8 driven by the fan 3 is disposed on the filter screen 9, an ash accumulation box 17 is disposed below the cleaning member 8, and preferably, when the cleaning member 8 rotates to above the ash accumulation box 17, dust in the cleaning member 8 can automatically fall into the ash accumulation box 17.
Specifically, the inside fixedly connected with bracing piece 2 of pipeline 1 takes a breath, fixedly connected with fan 3 on the bracing piece 2, the one end fixedly connected with flabellum that is close to filter screen 9 on the fan 3, during operation, fan 3 can drive the flabellum and rotate, forms the air current in pipeline 1 takes a breath, and fan 3 can also drive cleaning member 8 and rotate on filter screen 9 simultaneously, and when cleaning member 8 downwardly rotated to the top of ash accumulation case 17, the dust of sweeping into in the cleaning member 8 can fall into automatically under the effect of gravity and collect the storage in the ash accumulation case 17, prevents that the dust from being adsorbed on filter screen 9 once more because of the wind-force that fan 3 produced.
Further, the cleaning member 8 comprises an outer housing 81 arranged on the outer side of the filter screen 9 and an inner housing 82 arranged on the inner side of the filter screen 9, the transmission rod 7 penetrates through the center position of the filter screen 9 and is fixedly connected with the outer housing 81 and the inner housing 82, dust sweeping strips 83 radially arranged along the filter screen 9 are arranged in the outer housing 81 and the inner housing 82, and the dust sweeping strips 83 are attached to the filter screen 9.
