It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.

The present application will be described in detail with reference to the accompanying drawings and examples.

Referring to fig. 1 to fig. 2, fig. 1 is a schematic structural diagram of an atomizing assembly according to an embodiment of the present disclosure; fig. 2 is a schematic overall structure diagram of a mounting base according to an embodiment of the present application; in the present embodiment, an atomizing assembly 10 is provided. The atomizing assembly 10 is particularly useful for atomizing liquids and producing aerosols for use in various fields, such as medical, electronic cigarettes, and the like; in one embodiment, the atomizing assembly 10 can be used in an electronic atomizer for an electronic cigarette to atomize tobacco tar and generate smoke for a smoker to inhale, as exemplified in the following embodiments; of course, in other embodiments, the atomizing assembly 10 can also be applied to a hair spray apparatus for atomizing hair spray for hair styling; or applied to medical equipment for treating upper and lower respiratory diseases to atomize medical drugs.

Specifically, the atomizing assembly 10 includes an atomizing sleeve 11, where the atomizing sleeve 11 may be a hollow tubular structure, and a liquid storage cavity 111 is formed in the atomizing sleeve 11, and the liquid storage cavity 111 is specifically used for storing liquid, for example, tobacco tar; specifically, the atomizing sleeve 11 is further embedded with a mounting seat 112 and an atomizing core 113.

The mounting base 112 is disposed on one side of the liquid storage cavity 111 along an axial direction of the atomizing sleeve 11, the atomizing core 113 is disposed on one side of the mounting base 112 away from the liquid storage cavity 111, the mounting base 112 is opened with a first lower liquid channel 1121a and a second lower liquid channel 1121b facing the liquid storage cavity 111, and the first lower liquid channel 1121a and the second lower liquid channel 1121b communicate with the liquid storage cavity 111 and the atomizing core 113, so that liquid in the liquid storage cavity 111 can flow through the first lower liquid channel 1121a and the second lower liquid channel 1121b to enter the atomizing core 113. Specifically, the first lower liquid channel 1121a and the second lower liquid channel 1121b each have a side wall and a bottom wall, and a through hole 1124 is formed at the edge of the bottom wall, so as to communicate the liquid storage cavity 111 and the atomizing core 113 through the through hole 1124; specifically, the cross-section of the first lower liquid channel 1121a and the second lower liquid channel 1121b may be circular or irregular trapezoid.

Specifically, only the wall surface of the first lower liquid channel 1121a and the second lower liquid channel 1121b is provided with a plurality of guide grooves 1122, so that the surface tension of the liquid flowing through the first lower liquid channel 1121a is destroyed by the structure of the guide grooves 1122, and simultaneously, the liquid in the liquid storage cavity 111 is subjected to liquid absorption and flow guide by the capillary force of the guide grooves 1122, so that the liquid flows in the direction of the atomizing core 113; the second lower liquid channel 1121b does not have a guide groove 1122 formed therein, and in a specific embodiment, a wall surface of the second lower liquid channel 1121b is a smooth wall surface to facilitate air exchange of the generated air bubbles to the liquid storage cavity 111, and at the same time, an asymmetric structure is formed with the first lower liquid channel 1121a, and the asymmetric structure is utilized to break a stress balance of the air bubbles at the bottom of the lower liquid channel, so as to prevent the air bubbles from being retained to block the lower liquid channel, thereby avoiding affecting the air exchange performance of the atomizing assembly 10, and ensuring that the liquid can smoothly enter the atomizing core 113.

It is understood that the hydrodynamic force under the liquid in the first lower liquid channel 1121a is mainly from the gravity of the liquid itself and the capillary force of the guide groove 1122; the hydrodynamic force of the liquid in the second lower liquid channel 1121b is mainly from the gravity of the liquid itself, and compared with the first lower liquid channel 1121a, the hydrodynamic force of the liquid in the second lower liquid channel 1121b is smaller, so that the liquid in the liquid storage cavity 111 mainly flows through the first lower liquid channel 1121a to enter the atomizing core 113; further, it can be understood that the rising resistance of the bubbles generated by ventilation in the first lower liquid channel 1121a is larger than the rising resistance of the bubbles generated in the second lower liquid channel 1121b, and therefore, the bubbles mainly rise into the liquid storage cavity 111 through the second lower liquid channel 1121b, so that most of the liquid in the liquid storage cavity 111 and most of the bubbles generated by ventilation can pass through different lower liquid channels, separation of the bubbles and the liquid flowing through the channels is realized, the situation that the bubbles block the lower liquid channel to prevent the liquid from entering the atomizing core 113 is effectively avoided, and the problem of dry burning of the heating film in the atomizing core 113 is avoided.
