[0002] Air purifier is a kind of equipment that can disinfect and purify air simultaneously. In addition to being able to kill bacteria, viruses, mold, spores and other microorganisms, it can also remove formaldehyde, phenol and other organic pollutants in indoor air, and effectively improve the problem of smoke, smell, toilet odor, etc. Air purifier usually uses ultraviolet lamp, negative ion, electrostatic adsorption and ultrafine filtration method to sterilize or purify air.
[0003] The internal fan of the current air purifier is almost installed above the filter screen cylinder, and when working, air is taken in from the lower part of the air purifier, and the fan discharges the air filtered by disinfection from the mesh hole at the top of the machine. However, this design has the following disadvantages:
[0004] 1. The air flow turns sharply upward from the lower air inlet, making dust, particulate matter, bacteria and other "heavy objects" in the air easily miss the air inlet and not easily sucked into the machine. The upward air discharge can only continuously push the above-mentioned "heavy objects" upward, and the downward falling is relatively small, making it difficult to form repeated filtration and purification, affecting the purification efficiency.
[0005] 2. The fan is installed above the filter screen cylinder, so that the fan and the filter screen cylinder have a vertical gap, which is not tight enough, making it difficult for the filter screen cylinder to collect air and the air flow direction is scattered, so users generally feel that the noise is loud.
