Description

A Vibration Dropping Oil Atomizer

Technical field:

The invention belongs to the technical field of electronic smoke atomizers, and in particular relates to a vibration-following type oil drop atomizer.

Background technique:

Commercially available electronic cigarettes mostly use electric heating to heat the atomized e-liquid. Among them, the core component is the atomizing core, which includes electric heating elements such as heating wires or heating ceramics and its winding frames, glass fiber, organic cotton, cotton and other conductive materials. oil parts. The e-liquid in the oil storage element is transported to the electric heating element through the oil guide. When the electric heating element is energized for smoking, the high temperature of the electric heating element causes the e-liquid on the electric heating element to atomize, and the formed steam is cooled by the inhaled air into inhalable smoke (gas Sol).

Because the atomizing core and the e-liquid contained in the electric heating electronic cigarette have undergone high-temperature heating process, the high temperature may cause the material of the atomizing core to crack, fall off, carbonize or dissolve during smoking, and the heating element will also be partially damaged. Overheating causes dry burning, which reduces the sensory quality of smoking and poses potential health risks; some aroma components contained in e-liquid will also decompose and deteriorate at high temperatures, causing abnormal smell or aroma changes in smoking, which directly affects smoking quality.

People have always hoped to use non-heating atomization method to atomize e-liquid. At present, the mainstream method is electric heating atomization. Although people have been paying attention to the ultrasonic atomization method, the ultrasonic generator is very large, which makes the volume of electronic cigarettes too large. It is still desirable to have other means of vibratory atomization than ultrasonic vibration.

The purpose of the present invention is to solve the above problems, and to provide a vibration-following type oil drop atomizer.

The present invention uses a higher vibration frequency (usually higher than 30,000 times/minute), utilizes the position limiting and energy storage functions of the eccentric wheel, and adopts a magnet ring composed of a plurality of small magnets, and every two small magnets correspond to one convex of the rotor. In this way, the corresponding protruding part of the rotor is suspended in the middle of the two magnets. Therefore, the angle of each rotation of the drive shaft is small, so as to realize the vibration of the vibrator and drive the porous vibrating part in the follower type atomizer (oil storage atomizer) or vibrating diaphragm (drip oil atomizer) vibrates to break up the e-liquid into tiny droplets, which are carried out by the air in the form of atomized aerosol and inhaled from the suction nozzle.
