Embodiments of the present application provide a method, device, equipment, medium and product for controlling oscillating airflow. The method comprises: obtaining a current oscillation cycle signal of oscillating airflow generated by a sputum discharge device, and obtaining positive and negative half cycle peak values and positive and negative half cycle areas of the current oscillation cycle signal; judging a current human body inhale and exhale state; adjusting positive and negative half cycle pressure and positive and negative half cycle time of a next oscillation cycle signal of the oscillating airflow according to the positive and negative half cycle peak values and the positive and negative half cycle areas, so that a ratio of an absolute value of a negative half cycle peak value to an absolute value of a positive half cycle peak value of the next oscillation cycle signal of the inhalation phase is greater than a first value, and an absolute value of the positive half cycle area is not less than an absolute value of the negative half cycle area; a ratio of an absolute value of a negative half cycle peak value to an absolute value of a positive half cycle peak value of the next oscillation cycle signal of the exhalation phase is greater than a second value, and an absolute value of the positive half cycle area is not greater than an absolute value of the negative half cycle area. The scheme of the present application improves the effectiveness of airway secretion discharge.

A rotor cooling structure for a drive motor includes a rotor core with a central shaft hole. Several magnetic slots are arranged around the central shaft hole, each containing a magnet. Oil channels are formed in the sides of the magnetic slots, with the length of the oil channels inclined to the length of the magnetic slots. Two oil channels are provided in each magnetic slot, located on opposite sides. The end openings of the two oil channels are positioned opposite each other in the magnetic slots, and the two oil channels are parallel; alternatively, the end openings are positioned diagonally opposite each other in the magnetic slots, and the two oil channels are staggered. This invention provides cooling oil channels in the sides of the magnetic slots. Cooling oil enters the oil channels and contacts the magnets, increasing the heat dissipation area of ​​the magnets and effectively cooling both the magnets and the rotor core simultaneously, significantly improving the cooling efficiency of the magnets.
