3. The filter device designed by the present invention is provided with a fan in the second semi-circular channel. The fan generates negative pressure through rotation, which generates suction for the gas flowing through the vicinity of the square gap, ensuring that enough gas flows into the second semi-circular channel through the semi-circular gap. , and then flow to the half filter structure to be cleaned through the second semicircular channel to clean the filter structure.

4. The rotation of the filter element and the rotation of the fan are controlled by the same motor, which reduces the cost of the motor.

5. Due to the reciprocating switching of the filter structure, the rotation direction of the driving motor is also switched. The present invention realizes that the forward and reverse rotation of the driving motor can drive the fan to rotate in one direction through the adjustment mechanism, ensuring the normal operation of the exhaust air.
