The present invention relates to an electronic atomization device, comprising a vent tube, a heating assembly and a nozzle. The nozzle is arranged towards an inlet end of the vent tube, and is used for atomizing a liquid matrix and spraying same into the vent tube.

Abstract

The present invention relates to an electronic atomization device and a liquid storage atomization assembly thereof. An airflow channel used for the flow of high-speed airflow and at least two liquid inlet channels communicating with the airflow channel are formed in the liquid storage atomization assembly. A liquid matrix entering the airflow channel from the at least two liquid inlet channels is atomized under the action of the high-speed airflow flowing in the airflow channel.

Since the surface area of the liquid particles is expanded, heating evaporation is much easier, thereby achieving low-temperature atomization. In addition, supplying liquid to the airflow channel by means of the at least two liquid inlet channels may reduce an impact caused by flow pulsation, making an instantaneous flow rate more stable.

The high-speed airflow flowing in the airflow channel (622) causes a negative pressure to be generated in the airflow channel (622), the negative pressure being capable of sucking liquid matrix in the liquid storage cavity (610) into the airflow channel (622), and the liquid matrix entering the airflow channel (622) being atomized by the high-speed airflow flowing in the airflow channel (622). The resistive liquid supply channel (611) comprises a liquid supply tail section (621) close to the airflow channel (622), the liquid supply tail section (621) being a capillary channel. The continuous flowing liquid matrix is atomized into liquid particles with the assistance of the high-speed airflow, so that low-temperature atomization may be achieved. In addition, the capillary force in the liquid supply tail section (621) may reduce backflow of the liquid matrix to the liquid storage cavity (610) when suction ends, thereby preventing a delay in liquid supply during the next suction.

Abstract

An atomizing core (200), an atomizer (100), and an electronic atomization apparatus, comprising: a base (10). The base (10) has a liquid absorbing surface (11) and an atomizing surface (12). A liquid guide channel (13) communicating the liquid absorbing surface (11) and the atomizing surface (12) is provided in the base (10); the liquid guide channel (13) comprises at least two stages of channel segments (14) in communication with one another, each stage of channel segment (14) comprises at least one sub-channel (15), and the sub-channels (15) comprised in each stage of channel segment (14) are independent of one another and are all communicated with a channel segment of a neighboring stage; from a first end communicating the liquid guide channel (13) with the liquid absorbing surface (11) to a second end communicated with the atomizing surface (12), the equivalent diameter of each sub-channel (15) comprised in the channel segments (14) decreases with each stage. The equivalent diameter of the sub-channel (15) adjacent to the liquid absorbing surface (11) is relatively large so as to reduce the resistance encountered in the process of conveying an aerosol-generating substrate; and the equivalent diameter of the sub-channels (15) adjacent to the atomizing surface (12) is relatively small, as sub-channels with a small equivalent diameter have a larger driving force. The lower resistance and the higher driving force can increase a liquid guide rate, thus improving the atomization efficiency of the aerosol-generating substrate.
