Problems solved by technology
[0005] But even if the mature PWM voltage regulation method is used to adjust the voltage by adjusting the duty cycle to adjust the speed of the motor, the voltage regulator module will also have a certain power dissipation loss. For high-current equipment, such The loss has little effect, but for portable devices with low voltage and low current, such loss will occupy a considerable proportion. For example, the above-mentioned prior patent application uses a No. 5 battery with only tens of milliamperes of current If a traditional brushless silent fan is used, and a PWM regulator module is used to output a stable air volume, the power dissipation of such a module may sometimes be as high as 50%.

The invention discloses a multi-motor integrated fan which is provided with a blade, motors and a fan shell. The multi-motor integrated fan is of a single-blade and multi-motor structure which is formed by combining the blade and the two or more motors. The integrated fan is a vertical multi-motor integrated fan with the motor rotary shaft axes and the blade rotary shaft axis of the integrated fanbeing in a parallel state, and also can be a horizontal multi-motor integrated fan with the motor rotary shaft axes and the blade rotary shaft axis being in a non-parallel state, and the motors and the blade are in transmission through a clutch-type transmission structure; by rotating a spiral-shaped spiral groove or thread and matching with a protruded pin key or a threaded structure, gears arepushed to move in the axial direction and rotate, and transmission and engagement between the gears are achieved; and all the motors can adopt different end internal resistors, the basically-stable power or multi-stage different air volumes can be obtained without the stable voltage, and effects of high energy efficiency ratio and energy conservation are achieved.
Description
technical field [0001] The invention relates to a DC fan, in particular to a single-blade multi-motor assembly fan with a combination of multiple motors. Background technique [0002] For some battery-driven devices that need ventilation or heat dissipation, especially some small portable devices that need to be powered by batteries, a suitable high-efficiency and energy-saving fan has a very positive significance for the battery life. [0003] For example, the fan of a portable air purification device, due to its small size and low battery capacity, requires a more efficient and energy-saving fan to extend the battery life. The battery life of a general portable air purification device on the market is only about 3-5 hours. The equipment with a larger capacity battery is about 8 hours at most, because these existing portable air purification devices all adopt brushless silent cooling fans with low energy efficiency ratio. [0004] The applicant has previously applied for "...
