[0001] This utility model relates to the field of fan technology, and in particular to a pressurizing fan. Background Technology

[0002] A pressurized blower is a device that generates high-pressure gas through mechanical working principles. It converts low-pressure gas into high-pressure gas to meet the needs of industrial production and experiments under certain pressure conditions. The pressurized blower uses the rotational motion of components such as propellers or impellers to draw in and accelerate air, creating a pressure difference and thus forming a high-pressure airflow.

[0003] However, in existing technologies, since pressurizing fans need to draw in air during operation, they often draw in dust and fumes carried in the air. In order to ensure that the pressurizing fan can work continuously and stably, it is often necessary to perform routine maintenance and cleaning. Traditional pressurizing fan casings are usually cast in one piece, so when internal maintenance and cleaning are required, it is often necessary to disassemble the casing or internal structure as a whole, which is complicated. Therefore, we propose a pressurizing fan to solve the above problems. Utility Model Content
