Electric heating wire, ceramic atomization core and other resistance heating atomization methods are the mainstream of soot application at present, but due to the high atomization temperature and other adverse effects, resulting in Fried oil, low temperature atomization has become one of the development directions of glass pipes custom technology, ultrasonic atomization technology has the advantages of low temperature atomization.
Compared with pressurized low temperature atomization similar to compression medical atomizer, glass pipes custom practitioners seem to prefer ultrasonic atomization research.Admittedly, the ultrasonic atomization of glass pipes custom is farther than the pressurized low temperature atomization.
As most glass pipes custom practitioners know, hanley invented the first nicotine-based glass pipes custom product in 2003 and created brands such as tobacco.But what many people may not know is that atomization (like smoke) is not the dominant method of resistance heating today, but ultrasonic atomization.
According to hanli's 2003 patent, his electronic atomization smoke consists of high-frequency oscillation atomizer, airflow sensor, circuit board, battery, etc., among which the high-frequency oscillation atomizer USES the principle of ultrasonic atomization.
Due to the immature ultrasonic atomization technology, it is difficult for consumers to have a good atomization effect, so later electronic cigarette manufacturers turned to the large volume of smoke, high atomization efficiency of the resistance heating technology.
However, the study of ultrasonic atomized glass pipes custom has not been stopped completely.
For example, since 2015, hunan China tobacco has invested a lot of research and development efforts in ultrasonic atomization technology and applied for a series of protection patents.Now, more than 90% of the patents of glass pipes custom, which can be searched publicly, are held by hunan China tobacco, with more than 260 patents.
After continuing to invest in research and development, hunan China research group officially launched the first generation of USONICIG ultrasonic glass pipes custom -- rhythm in the UK in 2018.Once it was released, it attracted wide attention of the market.USONICIG was subsequently awarded the VAPE industry award for the second year in a row by Vapouround, the UK's leading electronic media.
The structure of ultrasonic atomizing glass pipes custom is relatively complex and the atomizing principle is simple, which makes the ultrasonic atomizing sheet vibrate through the tracing frequency circuit and atomize the smoke oil.
There are many difficulties in glass pipes custom ultrasonic atomization technology, among which ultrasonic atomization sheet and working control circuit are the two keys.
1. Ultrasonic atomizer
It is understood that the ultrasonic atomizer has solid piezoelectric ceramic sheet, metal/piezoelectric ceramic composite plate and other types.
Metal/PZT composites: the vibration of the metal diaphragm is driven by the plane vibration mode of the PZT sheet to atomize the liquid.However, the metal film of this structure is not firm, energy conversion efficiency is low, easy to fall off in the use process, affecting the service life.
The size of the micro-holes on the metal atomizer directly affects the atomization particle size of glass pipes custom liquid. It is said that the micro-holes on the atomizer of ultrasonic vibrating electronic atomizer can only reach 2 m(the number of domestic technical holes is only 3,000), which has become one of the bottlenecks in the development of glass pipes custom ultrasonic atomizer.
Solid piezoceramics: the surface of the piezoceramics is not porous and liquid cannot pass through.According to the patent, hunan China tobacco ultrasonic glass pipes custom has solid piezoelectric ceramic chip applications.
2. Work control circuit
The working circuit design of ultrasonic atomizer will affect the atomization stability and atomization amount.For example, the unreasonable design of the starting circuit will lead to the slow starting speed of the ultrasonic atomizer, which is manifested by the small amount of smoke in the first few months, and the unstable amount of smoke in the first few mouths when smoking glass pipes custom.
