[0002] A blower is a device used to increase the pressure or flow of gas. It usually consists of an electric motor and a rotating impeller, which sucks the gas and transmits it through a pipeline to the area where the pressure or flow needs to be increased. Blowers are widely used in industrial fields, such as steel, cement, chemical and other industries.

[0003] Publication No. CN209212593U discloses a dust-proof blower, comprising a base, a motor and a blower housing, wherein the motor and the blower housing are both located above the base, and the motor is located on one side of the blower housing, and one side above the blower housing is fixedly connected to an air inlet tube, an activated carbon filter and a high-efficiency filter are arranged inside the air inlet tube, and the activated carbon filter is located on one side of the high-efficiency filter, an air outlet is opened on the other side of the blower housing, a ventilation net is arranged inside the air outlet, and fan blades are installed inside the blower housing. The utility model has a simple structure, can effectively prevent dust from entering the blower, prevent dust from entering while ensuring air circulation with the outside world, and ensure the performance of the blower, and can effectively prevent external impact force from causing damage to the blower, thereby improving the service life of the blower and reducing the noise generated by the blower during operation, which is simple and convenient, saves time and effort, and is suitable for wide promotion and use. Although the blower is equipped with an activated carbon filter and a high-efficiency filter, the activated carbon filter and the high-efficiency filter can be used to preliminarily intercept dust and impurities in the air and prevent the dust layer from entering the blower casing. At the same time, a ventilation net is provided inside the air outlet to further prevent the dust layer from entering the blower, while ensuring air circulation with the outside world to prevent dust from entering and ensure the performance of the blower. However, after long-term use, a layer of dust will adhere to the surface of the filter, affecting the air intake effect, which needs to be improved. Utility Model Content
