Gear Motor Solution for Air Purifier

Project Background

With the improvement of living standards, people have higher and higher requirements for the quality of life, so more and more attention is paid to air quality. For this reason, many families are equipped with household air purifiers. Air purifiers essentially work by sanitizing the air, which may include pollutants, allergens, and toxins. They’re the exact opposite of essential oil diffusers and humidifiers, which add particles to indoor air.

The Structure of the Air Purifier

Air purifiers on the market today can use either passive or active air purification mechanisms or both at the same time to enhance air filtration efficiency. Depending on the type of filtering mechanism applied, the principle of operation of the air cleaner may have different specific structures.

The shape of the air purifier is mainly the case shell, filter section, air duct design, motor, power supply, LCD screen. The motor determines its life, the filter section determines the purification efficiency, and the air duct design, chassis housing, filter section, and motor determine the noise of the air purifier. Motor and fan: As the core and essential accessory of the air purifier, the motor fan is mainly used to control the circulation of air. The air with pollutants is sucked in, filtered, and then the clean air is blown out.

Features of Air Purifiers

In addition to the basic function of air purifiers, dust filters are also equipped with many other utilities such as deodorizing, bactericidal, fine dust filtration, creating negative ions, reducing static electricity, removing effects. cause allergies, moisturize, dehumidify, catch mosquitoes. to help purify the indoor air more effectively, bringing a fresh and healthy atmosphere to the user.

Along with advanced features, the air cleaner also has additional types of dust sensors, odor sensors, humidity sensors, air quality indicators, filter replacement warnings, etc. timer, sleep mode, power-saving mode, child lock, remote control, display screen, intuitive control panel system. so that users can use the machine conveniently, easier.

The Working Principle of the Air Purifier

The air purifier is mainly composed of a motor, a fan, an air filter, and other systems. Its working principle is: the motor and fan in the machine circulate the indoor air, and the polluted air passes through the air filter in the machine to remove various pollutants. Or adsorption, some Models of air purifiers will also inStall a negative ion generator at the air outlet (the high Voltage in the negative ion generator generates DC negative high Voltage during operation), which continuously ionizes the air to generate a large number of negative ions, which are sent out by the micro fan. The formation of negative ion airflow achieves the purpose of cleaning and purifying the air.

From the above, we can conclude that the motor plays a central role in the air purifier. After years of market research, Kinmore has developed an air purifier motor (KM-37B520-50.6-3.5147) that is reliable, super quiet and has a large Torque. We have provided motor power solutions for world-renowned companies.
