摘要： A cyclonic dust filter device (10) comprises a trunk (11), at least one first retaining wall (12), and at least one second retaining wall (13). The trunk (11) comprises a channel (111), an air inlet end (113) and an air outlet end disposed at two ends of the channel (111), and a dust filter hole (114) communicating with the channel (111). The first and second retaining walls (12, 13) are respectively disposed correspondingly to the dust filter hole (114). When a dust-containing airflow to-be-filtered (50) enters the channel (111) from the air inlet end (113), the dust-containing airflow forms a centrifugal airflow (51) that contains the dust (40) and is thrown out of the channel at a position of the dust filter hole (114). The first and second retaining walls (12, 13) are respectively disposed on a traveling path of the centrifugal airflow (51), so that the centrifugal airflow (51) sequentially strikes the first and second retaining walls (12, 13) to change the traveling direction and then discharges dust free clean air.

摘要： A power-driving motor (10) for power-driving bike is provided, of which the length is obviously larger than its width. A rotor (14) of the power-driving motor (10) is provided at the outside of the stator (12) so as to make the distance from the rotor (14) to the motor spindle (13) increase; namely, a torque increases and then an arm increases, thereby, making the motor spindle (13) supply a higher output torque to the connected driving unit when the rotor (14) rotates. The motor (10), based on the length of a conventional power-driving motor (10), may supply a higher output torque to solve the defect of a conventional motor implemented with an inner rotor (14) of which the output torque is insufficient.
