Technical field

The invention relates to an electronic cigarette, in particular to an oil-conducting ceramic and an ultrasonic atomizer.

Background technique

The existing ultrasonic electronic cigarette atomizer generally uses oil-conducting cotton to directly communicate with the oil tank to realize oil-conducting, such as aramid fiber, non-woven fabric, etc. During the use of the ultrasonic atomizer, as the ultrasonic atomization progresses, when the temperature of the e-liquid in the oil silo increases, not only the viscosity of the e-liquid decreases, but also the gap between the holes of the oil-conducting cotton increases, making the e-liquid in the oil-conducting cotton The flow rate on the surface is rapidly accelerated, and the amount of oil guiding of the oil-conducting cotton increases, so that the oil supply on the ultrasonic atomization sheet is too much, and it is easy to cause the ultrasonic atomization sheet to be soaked in the smoke oil, so that the start of the ultrasonic atomization sheet is slow. The smoke rate is slow, the smoke oil is not fully atomized, and problems such as oil inhalation and oil splashing are prone to occur.

Summary of the invention

The technical problem to be solved by the present invention is to overcome the shortcomings of the ultrasonic atomization sheet in the prior art that the atomization start-up is slow, the smoke generation speed is slow, and the e-liquid is not fully atomized, and it provides a fast start-up and high-speed smoke generation in the prior art. , Oil-conducting ceramic and ultrasonic atomizer with sufficient smoke oil atomization.

In order to solve the above technical problems, the present invention provides an oil-conducting ceramic, which includes a first cavity, a second cavity, and a third cavity that are vertically arranged, and the second cavity is arranged on the oil-conducting ceramic. In the central area of the first cavity, the bottom of the first cavity is provided with an air inlet, the top of the first cavity communicates with the top of the second cavity to form a first transfer interface, and the bottom of the second cavity is connected to the The bottom of the third cavity is connected to form a second transfer port, and the top of the third cavity is provided with a second air outlet. When the oil-conducting ceramic is used, the air inlet, the first cavity, and the second cavity , The third cavity is sequentially connected to form an S-shaped air flow channel.

When the oil-conducting ceramic of the present invention is used, the upper part of the oil-conducting ceramic is abutted by the oil storage assembly, and the lower part of the oil-conducting ceramic abuts the oil storage cotton on the ultrasonic atomization sheet, so that the air inlet, the first cavity, and the second cavity The third cavity and the third cavity are connected in turn to form a closed S-shaped air flow channel, and the second cavity of the oil-conducting ceramic is facing the central area of the ultrasonic atomizer, so as not to affect the center of the ultrasonic atomizer with the most intense high-frequency oscillation The ultrasonic atomization of the area is carried out, so that the ultrasonic atomization starts faster, the smoke emission speed is faster, and the smoke oil atomization in the center area is more fully, and the smoke discharged is larger. In addition, the airflow enters from the air inlet at the bottom of the oil-conducting ceramic to the first cavity, brings the smoke in the first cavity to the top of the second cavity, and then flows from the top to the bottom to mix with the smoke in the second cavity. Then enter the third cavity from the bottom of the second cavity, mix with the smoke of the third cavity, and then flow out from the top of the third cavity. In this process, due to the airflow direction in the second cavity and the smoke oil mist The direction of smoke emission is opposite, so that the smoke in the upper part of the second cavity is returned to the lower part of the second cavity, and the smoke generated in the upper part of the second cavity and the smoke generated in the lower part of the second cavity are removed from the third cavity together. The cavity is brought out, so the outflow of smoke is more concentrated, the density of smoke flowing into the user's mouth is greater, and the user experience is better. In addition, the direction of the airflow in the second cavity is opposite to the direction of smoke out of the e-liquid atomization, and the e-liquid droplets in the smoke can also be rebounded to the oil storage cotton, so as to prevent the smoke entering the user’s mouth from containing e-liquid droplets. Avoid the user's sensation of inhaling the e-liquid.

Further, the upper part of the oil-conducting ceramic is provided with oil storage holes, so that the distance between the ultrasonic atomization sheet and the e-liquid is closer, and the e-liquid can be transferred to the oil storage cotton and the ultrasonic atomization sheet as soon as possible, thereby making the ultrasonic atomization Start faster.

In between, the oil guide assembly includes the oil guide ceramic and oil storage cotton, the top of the oil guide ceramic abuts against the oil storage assembly, and the bottom of the oil guide ceramic supports the oil storage cotton On the ultrasonic atomization sheet of the atomization assembly, and the second cavity of the oil-conducting ceramic faces the central area of the ultrasonic atomization sheet, so that the central area of the ultrasonic atomization sheet corresponds to the oil storage cotton Exposed in the second cavity.

When the ultrasonic atomizer of the present invention is used, the e-liquid in the e-liquid in the e-liquid chamber enters the oil storage hole of the oil-conducting ceramic from the oil outlet of the oil storage assembly, and then the e-cigarette absorbs the e-liquid and transmits the e-liquid to the oil storage cotton The e-liquid is absorbed and stored by the oil storage cotton. When the oil storage cotton is saturated, the contact position of the oil-conducting ceramic and the oil storage cotton forms a stagnant state. Only when the ultrasonic atomization sheet is working, the oil storage cotton is subjected to the ultrasonic atomization sheet. The influence of the high-frequency oscillation caused by the e-liquid starts to flow. Since the oil storage cotton corresponding to the central area of the ultrasonic atomization sheet is exposed in the second cavity, the ultrasonic atomization in the central area of the ultrasonic atomization sheet with the most intense high-frequency oscillation will not be affected by the resistance of the oil-conducting ceramics. Therefore, the ultrasonic atomization of the ultrasonic atomizer can start faster, the smoke is faster, and the atomization is more complete. In addition, as mentioned above, the direction of airflow in the second cavity of the oil-conducting ceramic is opposite to the direction of smoke emission during ultrasonic atomization of e-liquid, which also makes the smoke generated by ultrasonic atomization more concentrated, and the amount of smoke flowing out is larger. The smoke oil droplets contained in the smoke are close to 0, which makes the user experience better.

Further, the bottom of the oil storage assembly is provided with an installation groove for installing oil-conducting ceramics, one side of the installation groove is provided with an air-intake groove, and the air-intake groove communicates with the air-intake port of the oil-conducting ceramic so The airflow entering from the atomization assembly can enter the air inlet of the oil guide ceramic through the air inlet groove, and then flow out to the air outlet channel through the first, second, and third cavities in sequence.

Further, the bottom of the oil storage assembly is provided with an oil outlet, the oil guide ceramic is provided with an oil storage hole, and the oil outlet is aligned with the oil storage hole, so that the e-liquid flowing out of the oil tank It can directly enter the oil storage hole, and the bottom surface of the oil storage hole is closer to the oil storage cotton than the top surface of the oil guide ceramic, so that the e-liquid in the oil storage hole can be led to the oil storage cotton faster by the oil guide ceramic , So as to increase the oil-conducting speed of the oil-conducting ceramics, and make the ultrasonic atomization sheet not easy to produce dry burning.
