The 450W vacuum cleaner has a suction power of 12-15KPa. It can dry the water on the carpet, and the suction is very strong, which fully meets the needs of households. 12kpa is 14kg. Suction is also known as negative pressure, 100kpa is about 1 kg (1 air pressure).
12kPa suction
With 12kPa suction, it can not only absorb the fine dust and hair on the surface, but also pull out the mites and their excrement hidden in the inner layer, and remove allergens. The Mijia Mite Removal Device has an independent motor to drive the roller brush to rotate at high speed and beat at the same time.
The electric roller brush rotates at 2300 revolutions per minute, and the soft bristles penetrate deep into the fabric gap, sweeping out the deep dust and mites, gently cleaning without hurting the fabric. In addition, the Mijia Mite Remover has a smooth air duct to deliver 50°C hot air, penetrates deep into the mattress to dry sweat and moisture, restores fluffy and dryness, and destroys the living environment of bacteria and mites.
Vacuum differential pressure cannot accurately and effectively represent suction
5000pa, or the kpa parameter of various vacuum cleaner models, represents the vacuum negative pressure of the vacuum cleaner, which is called "static pressure" in some places, because the motor of the vacuum cleaner discharges the air in the inner cavity of the machine, forming a state similar to vacuum, inside With less air, it naturally forms a negative pressure with the outside world.
It only represents the degree of vacuum generated by the vacuum cleaner host in a specific environment. It cannot truly represent the suction power of the vacuum cleaner. The most real parameter for judging suction power is "air flow". The name of this parameter is cfm, or indirectly, there is a parameter called AW ( Air watts) can be equivalent to the CFM parameter. This parameter represents the air flow taken away by the vacuum cleaner per unit time. The larger the parameter, the greater the suction.
Vacuum cleaner
Vacuum cleaners can be divided into vertical, horizontal and portable according to their structure. The working principle of the vacuum cleaner is to use the motor to drive the blades to rotate at a high speed to generate negative air pressure in the sealed casing to absorb dust. The output of domestic vacuum cleaners in my country is 7.405 million units.
