Abstract
The invention provides portable diffusion equipment of aerosol with a tiny particle diameter. An alternating current and direct current dual-purpose miniature air compression air source provides compressed air in two paths, wherein one path of compressed air is delivered to an ultrasonic two-phase flow repeated array type atomizing nozzle to form atomized aerosol, and the other path of compressed air pushes the atomized aerosol formed just now to sieve the aerosol with the tiny particle diameter through an aerosol pre-sieving cavity to rapidly diffuse outwards; the aerosol with a larger particle diameter is partitioned by sieving partition plates in the pre-sieving cavity and flows back to the atomizing nozzle for atomizing and sieving again, the particle diameter of the aerosol is determined by the space of the sieving partition plates, and the amount of the atomizing nozzles can be determined according to an atomizing requirement so that the atomizing capacity is higher than liquid speed to ensure that the atomizing speed and concentration can be controlled. The portable diffusion equipment has the beneficial effects of small volume, convenience in carrying, tiny and controllable particle diameter of the atomized aerosol and capability of presetting the speed and the concentration for atomizing the aerosol and meets the atomizing requirement in fields such as medicine, environmental protection, military, industry and the like with special requirements.
