  • the side wall may have a cylindrical structure, and the airflow forms a swirling airflow in the working chamber, so that the dust in the airflow generates centrifugal force and moves along the side wall of the working chamber under the action of centrifugal force, and the side wall of the working chamber has a cylindrical structure,
  • the resistance of the dust is small, and the dust can maintain a large centrifugal force and is easily thrown out.
  • the side surface of the working chamber is provided with a dust collecting port, and the dust collecting port is in communication with the dust collecting chamber 2.
  • the two sides of the dust collecting chamber 2 are tangential to the side of the working chamber at both ends of the diameter of the cylindrical structure, and the two sides extend to form a closed dust collecting chamber 2.
  • the working chamber and the dust collecting chamber 2 can be connected through the dust collecting port, and the dust collecting port can be larger or smaller, and the dust collecting port is more likely to cause the airflow to break into the dust collecting chamber 2 when the dust collecting port is large.
  • the side surface of the dust collecting chamber 2 and the side surface of the working chamber are an integral structure.
  • the working chamber and the dust collecting chamber 2 can be an integral space.
  • a spiral airflow is formed, and the range of motion can be regarded as a working chamber, and the dust is extracted by the centrifugal force and the gravity. , falling into the dust collecting chamber 2, the dust deposition efficiency is high, and the dust removing effect is good. As shown in Figure 5.
  • the present invention also provides a dust removing apparatus comprising a power component and a filtering device according to each of the above embodiments, wherein the power component is located in the air outlet passage 61, and the airflow enters the filter 3 of the filtering device. After flowing to the power components.
  • the filtering device has the above technical effects, and therefore the dust removing device having the filtering device also has a corresponding technical effect. Please refer to the prior art for the structure of other parts of the dust removal equipment, and will not be repeated here.
