Problems solved by technology

[0008] Common mechanical atomization and ultrasonic atomization methods have problems such as complex structure, high cost, high power consumption, large atomized particle diameter, low atomization efficiency, and small atomization flow rate. In order to meet the needs of new industrial applications, the development Green and efficient atomization technology has become one of the foundations and key technologies for the development of new industrial technologies. While ensuring excellent atomization effects, improving atomization efficiency and atomization quality, it minimizes power consumption and reduces environmental pollution. , to achieve green and low-carbon production, easier to control and more environmentally friendly

[0009] In order to overcome the shortcomings of the above atomization technology, the patent document with the publication number CN102500502A discloses a two-stage ultrasonic vibration atomizer, which adopts a sandwich transducer structure, has a large power capacity, and can atomize The advantage of strong ability, but the ultrasonic atomizer also has some defects. The inclined micro-holes of the primary atomizing nozzle of the atomizer are difficult to manufacture and install. To reduce the droplet diameter, the vibration frequency of the system needs to be increased, which further increases the It is difficult to manufacture, and the diameter of the atomized droplets on the secondary atomization surface is not uniform enough. Although the atomization effect is improved compared with the general ultrasonic vibration atomizer, the problem of uneven droplet diameter has not been fundamentally solved.
