Ultrasonic nebulizer

Abstract

The invention relates to an electronic smoking set, in particular to an ultrasonic nebulizer which comprises a tar guide assembly (2), the tar guide assembly comprises tar guide ceramic (21) and tar storage cotton (22), a containing groove is formed in the lower surface of the tar guide ceramic, the tar storage cotton is arranged in the containing groove, the lower surface of the tar guide ceramic is arranged to be a rough surface, and the oil storage cotton and the rough surface are propped against the atomizing surface of the ultrasonic atomizing sheet. An air outlet channel penetrating through the oil guide ceramic is formed in the middle of the oil guide ceramic, the oil storage cotton is exposed out of the bottom of the air outlet channel, an air guide groove is formed in the lower surface of the oil guide ceramic, and the air guide groove is communicated with the bottom of the air outlet channel. According to the invention, the phenomenon of local dry burning of the ultrasonic atomization sheet can be avoided, and the supply and demand of the tobacco tar can reach the oil supply balance when the ultrasonic atomization sheet works or not.

Description

technical field [0001] The invention relates to an electronic cigarette set, in particular to an ultrasonic atomizer. Background technique [0002] The existing ultrasonic electronic atomizers generally use oil-guiding cotton to directly connect with the oil tank to realize oil-guiding. This kind of oil-guiding cotton has the following problems: [0003] 1. With the progress of ultrasonic atomization, when the temperature of the e-liquid in the oil tank increases, the viscosity of the e-liquid decreases, so that the flow rate of the e-liquid on the oil-conducting cotton increases rapidly, and the oil-conducting amount of the oil-conducting cotton increases, so that Too much oil supply on the ultrasonic atomizing sheet may easily cause problems such as the ultrasonic atomizing sheet being soaked in e-liquid; [0004] 2. After the oil-conducting cotton absorbs the e-liquid, the pore gap of the oil-conducting cotton increases. When the temperature of the e-liquid increases wit...

Problems solved by technology

[0003] 1. With the progress of ultrasonic atomization, when the temperature of the e-liquid in the oil tank increases, the viscosity of the e-liquid decreases, so that the flow rate of the e-liquid on the oil-conducting cotton increases rapidly, and the oil-conducting amount of the oil-conducting cotton increases, so that Too much oil supply on the ultrasonic atomizing sheet may easily cause problems such as the ultrasonic atomizing sheet being soaked in e-liquid;

[0004] 2. After the oil-conducting cotton absorbs the e-liquid, the pore gap of the oil-conducting cotton increases. When the temperature of the e-liquid increases with the progress of ultrasonic atomization, the viscosity becomes smaller, and the pore gap of the oil-conducting cotton increases. The oil conduction rate of the e-liquid on the oil-conducting cotton is accelerated, and it is easy to cause the phenomenon that the ultrasonic atomizing sheet is soaked in the e-liquid, resulting in insufficient atomization of the e-liquid by the ultrasonic atomizing sheet, and the smog has a large sense of particle size, so users may smoke. The feeling of smoke oil, the experience is not good

[0005] In addition, when the ultrasonic atomizing sheet is working, the vibration frequency and intensity of different positions of the same ultrasonic atomizing sheet are different. dry burning phenomenon

For example, the central position of the ultrasonic atomizing sheet has the highest atomization efficiency, so the e-liquid in the center of the ultrasonic atomizing sheet is easily consumed, resulting in the phenomenon of dry burning in the center of the ultrasonic atomizing sheet; After the chip works for a period of time, when the oil-conducting rate of the vape oil on the oil-conducting cotton is accelerated, the ultrasonic atomizing chip is easily soaked in the vape oil; The oil conduction rate on the cotton slows down, and the center of the ultrasonic atomizer is prone to dry burning, which affects the taste of the smoke
