Title:
ATOMIZING CORE, ATOMIZER, AND ELECTRONIC ATOMIZATION APPARATUS
Document Type and Number:
WIPO Patent Application WO/2023/151326
Kind Code:
A1
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.
