The description of the patent application number 201210492062.X in the prior art provides a feather duster powered by electricity, which includes a dust brush and a handle. The bottom of the handle is provided with a battery compartment cover and a motor. The front ends of the motor are in order A dust cover and a dust cabin are provided, and a switch is provided outside the handle, and the front end of the handle is connected to a dust brush with bristles on the dust brush, and dust suction holes are distributed, and the dust suction holes are connected with the dust cabin. The disadvantages of the prior art are as follows: the feather duster has insufficient dust suction power, resulting in poor dust suction effect. It is provided with a dust cover and a dust cabin, has a complex structure, high manufacturing cost and difficult internal cleaning. The description of the patent application number 200720044712.9 in the prior art provides a feather duster that uses electricity as the driving force. It includes a duster head and a handle. A battery, a DC motor, a planetary gear reducer and a shaft coupling are connected to the shaft coupling, and a button is installed on the handle, and the button is connected to the battery and the DC motor through a wire. The shaft coupling is connected with the duster rod through the duster rod connecting sleeve and the duster rod connector. The disadvantages of the prior art are as follows: the feather duster has a complicated structure and high manufacturing cost.

When in use, turn on the switch, the circuit of the wire is connected, the battery in the battery compartment supplies power to the motor, and the motor serves as a power source to drive the fan blades to rotate at high speed. Utilizing Bernoulli's principle, the faster the fluid flow rate, the lower the pressure, and a low-pressure environment is achieved inside the grip. At this time, the feather duster can be divided into high and low pressure areas with the fan blades as the boundary, so as to realize the negative pressure difference. When cleaning, the dust raised by the feather duster enters the feather rod through the suction hole on the feather rod with the air, and then adsorbs on the filter cloth. The air filtered by the filter cloth enters the handle through the ventilation plate with round holes, and then is discharged through the through holes of the handle. This avoids flying dust and improves cleaning results.

When the filter cloth needs to be replaced, unscrew the threaded connection between the feather rod and the handle, and take off the ring to replace it. After replacement, install in the opposite direction.

This structural design uses Bernoulli's principle, which is reasonable and simple. It is not only convenient to operate, low in labor intensity, and good in cleaning effect, but also avoids the problem of flying dust during cleaning. The invention combines the advantages of both the feather duster and the vacuum cleaner, has low cost, strong practicability, is easy to manufacture, and is beneficial to popularization and application.
