The following describes the present disclosure in detail with reference to the accompanying drawings and embodiments.

Referring to <FIG>, <FIG> is a schematic structural view of an atomization assembly according to an embodiment of the present disclosure; and <FIG> is a schematic view of an overall structure of a mounting base according to an embodiment of the present disclosure. An atomization assembly <NUM> is provided in this embodiment. The atomization assembly <NUM> may specifically be configured to atomize liquid and generate smoke for application in different fields, for example, medical treatment, e-cigarettes, etc. In an embodiment, the atomization assembly <NUM> may be applied to an e-cigarette for atomizing tobacco oil and generating smoke to be inhaled by a user, which is taken as an example in all the following embodiments. Certainly, in other embodiments, the atomization assembly <NUM> may also be applied to a hair spray device to atomize a hair spray for hair styling, or applied to a medical device for treating upper and lower respiratory system diseases to atomize medical drugs.

In some embodiments, the atomization assembly <NUM> includes a sleeve <NUM>, where the sleeve <NUM> may specifically be a hollow tubular structure, and a liquid storage cavity <NUM> is defined on the sleeve <NUM>. The liquid storage cavity <NUM> is specifically configured to store liquid, such as tobacco oil. In some embodiments, a mounting base <NUM> and an atomization core <NUM> are further embedded in the atomization sleeve <NUM>.

The mounting base <NUM> is arranged on the side of the liquid storage cavity <NUM> in the axial direction of the sleeve <NUM>, the atomization core <NUM> is arranged on the side of the mounting base <NUM> away from the liquid storage cavity <NUM>, and a first liquid supplying channel 1121a and a second liquid supplying channel 1121b are provided on the mounting base <NUM> facing the liquid storage cavity <NUM>. The first liquid supplying channel 1121a and the second liquid supplying channel 1121b are in communication with the liquid storage cavity <NUM> and the atomization core <NUM>, so that the liquid in the liquid storage cavity <NUM> can flow through the first liquid supplying channel 1121a and the second liquid supplying channel 1121b, and enter into the atomization core <NUM>. In some embodiments, the first liquid supplying channel 1121a and the second liquid supplying channel 1121b both include the side wall and the bottom wall, and through holes <NUM> are respectively provided at the edges of the bottom walls, such that each of the first liquid supplying channel 1121a and the second liquid supplying channel 1121b is in communication with the liquid storage cavity <NUM> and the atomization core <NUM> through the through hole <NUM>. In some embodiments, cross-sections of the first liquid supplying channel 1121a and the second liquid supplying channel 1121b may be in circular shape or in an irregular trapezoid shape.

In some embodiments, in the first liquid supplying channel 1121a and the second liquid supplying channel 1121b, a plurality of guide grooves <NUM> are provided only on the wall surface of the first liquid supplying channel 1121a, so as to destroy surface tension of liquid flowing through the first liquid supplying channel 1121a by using the structure of the guide grooves <NUM>. Meanwhile, the liquid in the liquid storage cavity <NUM> is absorbed and guided by capillary forces of the guide grooves <NUM> (that is, the plurality of guide grooves <NUM> connect the liquid storage cavity <NUM> and the atomization core <NUM> with capillary force), so that the liquid flows in the direction toward the atomization core <NUM>, and no guide groove <NUM> is defined in the second liquid supplying channel 1121b. In an embodiment, the wall surface of the second liquid supplying channel 1121b is a smooth wall surface to facilitate rising of bubbles generated by ventilation to the liquid storage cavity <NUM>. Meanwhile, the second liquid flowing channel 1121b and the first liquid flowing channel 1121a form an asymmetric structure, which destroy force balance of the bubbles at the bottoms of the liquid supplying channel, thereby preventing the bubbles from being trapped and blocked in the liquid supplying channel, reducing the impact on the ventilation performance of the atomization assembly <NUM>, and ensuring that the liquid can smoothly enter the atomization core <NUM>.

It may be understood that the liquid supplying power of the liquid in the first liquid supplying channel 1121a mainly comes from gravity of the liquid itself and the capillary forces of the guide grooves <NUM>, while the liquid supplying power of the liquid in the second liquid supplying channel 1121b mainly comes from gravity of the liquid itself. The liquid supplying power of the liquid in the second liquid supplying channel 1121b is less than that of the liquid in the first liquid supplying channel 1121a. Therefore, the liquid in the liquid storage cavity <NUM> mainly flows through the first liquid supplying channel 1121a and enters into the atomization core <NUM>. Furthermore, it may be understood that the bubbles generated by ventilation bear greater rising resistance in the first liquid supplying channel 1121a than in the second liquid supplying channel 1121b. Therefore, the bubbles rise into the liquid storage cavity <NUM> mainly through the second liquid supplying channel 1121b, so that most of the liquid in the liquid storage cavity <NUM> and most of the bubbles generated by ventilation can pass through different liquid supplying channels. In this way, it may be possible to realize the separation of the bubbles and the liquid via channels, which effectively prevents a problem that the liquid cannot enter the atomization core <NUM> due to the case that liquid supplying channels are blocked by the bubbles, thereby preventing a heating film in the atomization core <NUM> from dry heating.

In an embodiment, the plurality of guide grooves <NUM> may specifically be formed of a plurality of liquid guiding walls <NUM> protruding from the inner surface of the first liquid supplying channel 1121a at interval, and the plurality of liquid guiding walls <NUM> extend along the axial direction of the first liquid supplying channel 1121a.

In some embodiments, the third side of each liquid guiding wall <NUM> is flush with or below the first surface of the mounting base <NUM>.

In some embodiments, the foregoing liquid guiding walls <NUM> may be integrally formed with the side wall where the inner surfaces of the first liquid supplying channel 1121a are arranged. In another embodiment, for the existing mounting base <NUM> in which both the two first liquid supplying channel 1121a include smooth inner surfaces, the foregoing liquid flowing walls <NUM> may be fixed to one of the inner surface of the first liquid supplying channel 1121a by gluing, so as to change the two first liquid supplying channels into an asymmetric structure.
