The working principle is as follows: when the dust collector is powered on, a start operation key is pressed to start the high-pressure fan 9, strong negative air pressure is formed at an air inlet of the fan 9, the internal space of the filter 8, the inner cavity of the purification chamber 3, the inner cavity of the inner cylinder 7, the inner cavity of the outer cylinder 2, the adapter, the dust collection pipe and the internal space of the dust collection scraping head 38 which are mutually connected with the high-pressure fan synchronously generate strong negative air pressure, external original air flow sequentially flows through the spaces from the dust collection scraping head 38 under the action of the negative pressure, and is finally discharged from an air outlet of the high-pressure fan 9 and an air outlet 34 arranged on the outer wall of the fan chamber 33; in the process, when original airflow tangentially enters the outer cylinder body 2 through the adapter, high-speed downward spiral airflow can be formed in the outer cylinder body 2, large and medium particle size dust, liquid drops and a part of small particle size dust in polluted airflow are far away from the axis of the spiral airflow under the action of centrifugal force and move downwards along the direction of the airflow along the inner wall of the outer cylinder body 2, finally the polluted airflow enters the first chamber 4 of the ash bin 1 through the slow flow plane of the separation cone 13 to be accumulated, relatively clean airflow after primary separation enters the inner cylinder body 7 through the air holes 6 formed in the separation cone 13, and the primary purification of the original airflow is completed in the cyclone separation chamber; the air flow after the primary purification sequentially passes through the inner cylinder 7 and the connecting air passage to enter the purification chamber 3 and the filter 8, and residual small-particle-size dust in the air is separated in the process of passing through the filtering surface of the filter 8, so that the secondary purification of the air flow is completed, and the purification requirement is met; the air flow after the secondary purification is finally discharged through the high pressure fan 9 and the air outlet 34, and is finally purified when passing through the filter screen 35 on the air outlet 34. The output power of the high pressure fan 9 can be adjusted through an operation key in the working process of the dust collector, so that the negative pressure value and the air suction quantity of the high pressure fan 9 can be adjusted to adapt to different working environments; when excessive dust is accumulated on the surface of the filter 8, the vibration motor 18 can be started manually or automatically through an operation key, the vibration motor 18 drives the filter 8 to vibrate synchronously through the elastic base 16, and the accumulated dust on the surface of the filter 8 is separated and falls into the second chamber 5 of the dust bin 1 to be accumulated, so that the purpose of automatic purification of the filter 8 is achieved; after the dust and the waste liquid in the first chamber 4 and the second chamber 5 of the ash bin 1 are accumulated to a certain degree, the dust and the waste liquid can be intensively discharged and processed by opening the door of the ash bin 1.

Large particle impurities and liquid pollutants in the air flow are filtered in the primary purification process, a good and safe filter 8 using environment is created, and the service life of the filter 8 is prolonged. The purifying chamber 3 can accommodate a filter 8 with larger size, thereby greatly increasing the filtering area of the secondary purifying process, reducing the filtering wind speed and improving the purifying capacity of the dust collector to fine dust. The fan power, the number of fans, the number of filters 8 and the volume of the ash bin 1 can be flexibly adjusted to adapt to different use requirements. The dust collector has longer service life and can be free from or rarely maintained in the replacement period of the filter 8 and the fan 9.
