Problems solved by technology

[0002] In factories, negative pressure fans are generally used to exhaust the gas or floating particles generated during the processing and production process in the factory building, especially when extracting some smoke and dust, because the dust is easy to accumulate in the fan, resulting in the need for frequent cleaning of the fan. , otherwise, the fan cannot work smoothly, and the workload is relatively large. In the prior art, manual cleaning is often used, which is very inconvenient

Abstract

The invention provides a self-cleaning negative pressure blower which comprises a first cylindrical shell, a first cleaning assembly, a first filter screen, a suction assembly, a second filter screen, a second cleaning assembly and a dirt collecting assembly, wherein a first end of the first cylindrical shell along the axial direction is provided with an indoor port, and a second end is an outdoor port; the first cleaning assembly, first filter screen, suction assembly, second filter screen and second cleaning assembly are respectively arranged in the cavity of the first cylindrical shell, and are sequentially arranged along the first cylindrical shell from the first end to the second end; the dirt collecting assembly comprises a drainage pipe and a collecting bag; a first end of the drainage pipe is provided with a first branch pipe and a second branch pipe; the first branch pipe and second branch pipe are respectively communicated with the inner cavity of the first cylindrical shell; and a second end of the drainage pipe is connected with the collecting bag. The self-cleaning negative pressure blower is simple and practical, can implement self-cleaning, and saves time and labor.

Description

technical field [0001] The invention relates to the technical field of fans, in particular to a self-cleaning negative pressure fan. Background technique [0002] In factories, negative pressure fans are generally used to exhaust the gas or floating particles generated during the processing and production process in the factory building, especially when extracting some smoke and dust, because the dust is easy to accumulate in the fan, resulting in the need for frequent cleaning of the fan. , otherwise, the fan cannot work smoothly, and the workload is relatively large. In the prior art, manual cleaning is often used, which is very inconvenient. Contents of the invention [0003] Based on the technical problems existing in the background technology, the present invention proposes a self-cleaning negative pressure fan. [0004] A self-cleaning negative pressure fan proposed by the present invention includes a first cylindrical shell, a first cleaning assembly, a first filte...
