Technical Field

The utility model relates to the technical field of filters, in particular to an air inlet filter with a multi-layer filtering structure.

Background technique

The magnetic levitation centrifugal blower is directly driven by its internal magnetic levitation high-speed motor and high-efficiency three-dimensional flow impeller, so it is contactless, frictionless, and requires no lubrication, and it eliminates rotational losses. That is, it is efficient and reliable, and has a compact layout and easy installation. As a result, its share in the current blower market continues to rise.

The existing application number is: 202222769284.3, which is a magnetic levitation blower, including a fixed shell, wherein the four corners of the inner bottom wall of the fixed shell are fixedly connected to a first support frame, the inner wall of the first support frame is fixedly connected to a damping rubber pad, the inner wall of the damping rubber pad is provided with a second support frame, the upper surface of the second support frame is fixedly installed with a blower body, one side of the air inlet end of the blower body is fixedly connected to a fixed frame, the inner side wall of the fixed frame is provided with a sliding groove, the inner wall of the sliding groove is slidably connected to a sealing plate, the front and rear sides of the fixed frame are fixedly connected to support plates, the inner edges of the support plates are provided with first fixing holes, one side of the first fixing hole is fixedly connected to a fixing cylinder, and one side of the fixing cylinder is slidably connected to a fixing column.

During the use of the above technology, when the filter needs to be cleaned, the two fixing columns are first pulled outward at the same time, so that the fixing columns will pull the slider and the spring to move to one side in the fixing cylinder until one end of the fixing column can be completely moved out of the second fixing hole, and then the sealing plate is pulled out from the fixing frame, and the filter on the sealing plate can be cleaned. However, in actual use, a single filter cannot achieve a good filtering effect, and because the fixing columns are not provided with corresponding limiting components, when a person pulls the two fixing columns with both hands, another person is required to pull the sealing plate out of the fixing frame, which makes it impossible for the person to operate alone, that is, it is inconvenient for the person to clean the filter, and it will cause the blower to be shut down for a long time; therefore, in order to solve the above technical problems, we propose an air inlet filter with a multi-layer filtering structure.
