Provide discount motor vacuum cleaner, the working principle of vacuum cleaner fan: the working principle of the general centrifugal fan is basically the same, when the impeller rotates at high speed, all parts of the air in the impeller are also driven to rotate together. At this time, the air in the center of the impeller Due to the centrifugal force, it will be thrown to the edge of the impeller, and a vacuum is formed at the center of the impeller. Therefore, under the action of the pressure difference, the external air will continue to flow in and supplement to the center of the impeller, so that the fan has " The ability to suck in air. Since the speed of air leaving the impeller blades in rotation is much greater than the airflow velocity in the space around the impeller, this makes the gas in the movement part of the kinetic energy converted into static pressure energy, in the process of converting kinetic energy into static pressure energy In the hood, the fan's hood space presents a positive pressure, so that the fan has the ability to transfer gas into the introduction, and in the introduction, part of the kinetic energy is converted into static pressure energy, and then flows into the motor, while cooling the motor, and finally through the outlet The main characteristics of the motor: After the vacuum cleaner is connected to the power supply, the motor drives the impeller to rotate at a high speed, so that the air between the blades on the impeller is discharged outward under the action of centrifugal force, and the air in the dust collection bin will soon be sucked up. , The air pressure in the cavity is much lower than the atmospheric pressure. In this way, the outside air will continue to pour into the dust collection cavity through the suction nozzle and the plastic tube, and the external dust and dust will be sucked into the cavity to achieve dust collection. Purpose: The air sucked into the dust bin is discharged by the motor after passing through the dust filter cover, and dust and other materials cannot pass through the dust cover but stay in the dust removal tank, and will be removed after accumulating to a certain extent.
