Blower Electrostatic Neutralization Apparatus for Motor Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing blowers generate electrostatic charges due to friction between the fan and air during rotation, which can accumulate and damage electrical motors or other electronic components if not discharged in time.
Innovation Solution
Incorporating an electrostatic neutralization apparatus with conductive ends positioned within the air duct passage, one close to the fan and the other closer to the air outlet, to collect and neutralize electrostatic charges through an electrical connection, thereby reducing electrical leakage and protecting the motor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the fan rotates continuously to generate airflow, then the blower can perform its cleaning function, but electrostatic charges accumulate and may damage the motor or electronic components
Solution Approach 1:
The patent introduces an electrostatic neutralization apparatus as an intermediary component between the fan and the motor. This apparatus includes conductive elements positioned within the air duct passage that provide a controlled path for electrostatic charge dissipation, preventing charge accumulation that would otherwise damage the motor while allowing the fan to continue generating airflow normally
2Productivity
If the fan rotates at high speed to improve cleaning efficiency, then productivity increases, but electrostatic charge generation increases proportionally
Solution Approach 1:
The patent converts the harmful electrostatic charges generated by high-speed fan rotation into a beneficial controlled discharge process. The electrostatic neutralization apparatus provides designated discharge paths that safely导 out the charges, transforming what would be a damaging accumulation into a controlled, harmless dissipation process that occurs continuously during operation

AI summary
A blower has a fan, a motor, an air duct assembly having an air duct passage with an air inlet and an air outlet where the fan rotates to drive the airflow to enter into the air duct passage from the air inlet and to be exposed out of the air outlet, and an electrostatic neutralization apparatus. The electrostatic neutralization apparatus includes a first conductive end and a second conductive end wherein the first conductive end is located within the air duct passage and close to the fan and the second conductive end is also located within the air duct passage. The electrostatic neutralization apparatus of the blower effectively neutralizes electrostatic charges generated by the fan.
