Design Principle of Rotating Module for Cordless Handheld Vacuum Cleaners
Although there are many types of cordless handheld vacuum cleaners, they have a similar structure which is composed of shell, motor, automatic charging base, virtual wall transmitter, sensor head, switch, electric brush, dust bag, etc. At present, most vacuum cleaner motors mainly adopt AC series excitation motors and permanent magnet DC brush motors, both of whose service life is confined to the service life of carbon brush. This leads to short service life, large size, and weight, as well as low efficiency, which cannot meet the market demand well.
Based on the motor requirements of vacuum cleaner industry (compact size, lightweight, long service life, and high performance), by adding the high-torque planetary gear motor to the suction head of the brush, ZHAOWEI takes advantage of the rotating module for cordless handheld vacuum cleaners to control the motor to drive the blade to operate at high speed and simultaneously supplement intake fan with the air in dust collection part. The instantaneous vacuum will be achieved in the dust collector, which results in the negative pressure gradient with the external atmosphere. This design enables ultrastrong suction of cordless handheld vacuum cleaners and endurable power source so that the brushless motor in the vacuum cleaner takes pride in large suction capacity, high power and low noise, which can be applied to most of the floors, floor tiles, floor mats, and short-haired carpets. At the same time, the soft velvet roller tackles hair easily, contributing to deep cleaning.
