It may burn out parts such as power module.
The power module includes a transformer, voltage regulator, isolated power supply, filter capacitor, and rectifier.
Power module of these devices, not necessarily all burned, burned black is bad, not black may be good, if you know, you connected to the 110V electricity into, with a multimeter measurement, step by step, to see which is bad, which is good, the bad will be replaced by a good one. ? If you don't know how, you will have to return to fix it.
Air purifier, also known as air cleaner, air freshener, purifier, refers to the ability to adsorb, decompose or transform a variety of air pollutants (generally including PM2.5, dust, pollen, odors, formaldehyde and other decorative pollution, bacteria, allergens, etc.), to effectively improve the cleanliness of the air of the products are divided into domestic , commercial, industrial, building.
Air purifier refers to the ability to adsorb, decompose or transform a variety of air pollutants, effectively improve air cleanliness of the product. In the home, medical, industrial applications, the home field is divided into systematic fresh air system (also divided into two sub-categories of heat exchange and no heat exchange) and stand-alone two categories, mainly to solve the problem of indoor, underground space, car air pollution due to renovation or other reasons. Since the release of air pollutants in relatively enclosed spaces is characterized by persistence and uncertainty, the use of air purifiers to purify indoor air is one of the internationally recognized methods to improve indoor air quality.
The national "air purifier" standard defines air purifier as "a device that separates and removes one or more pollutants from the air. The air pollutants have a certain ability to remove the device. Mainly refers to the room used in the single air purifier and centralized air conditioning ventilation system within the module air purifier.
Air purifiers originated for firefighting purposes when, in 1823, John and Charles Dean invented a new type of smoke protection device that allowed firefighters to avoid smoke while fighting fires.
In 1854, a man named Johns Tenhouse built on his predecessor's invention: through several attempts, he learned that adding charcoal to an air filter filtered harmful and poisonous gases from the air.
During World War II, when the U.S. government began conducting research on radioactive materials, they needed to develop a way to filter out all the harmful particles to keep the air clean enough for scientists to breathe, and so the HEPA filter was born. HEPA filters were very popular for a time in the 1950s and 1960s, and were very popular with bomb shelter designers and builders.
Into the 1980s, the focus of air purification had shifted to air purification methods, such as home air purifiers. While filters in the past were very good at removing bad odors, toxic chemicals and poisonous gases from the air, but could not remove mold spores, viruses or bacteria, the new air purifiers for home and office use not only cleaned the air of poisonous gases, but also purified the air by removing airborne bacteria, viruses, dust, pollen, mold spores and more.
Air purifiers have been designed and built in many different ways, and each change in technology has brought significant results in improving people's indoor air quality. All of this is done with one goal in mind: to improve the quality of people's lives by cleaning up their indoor air.
Most of the air purifiers on the market are composed of: chassis shell, filter section, air duct design, motor, power supply, LCD display and so on. Decide the life of the motor, to determine the purification efficiency is the filter section, to determine whether the quiet is the air duct design, chassis shell, filter section, motor.
