[0031] See also Figure 1 and Figure 2 , Figure 1 is a schematic diagram of the structure of the electronic atomization component 1 provided by the present invention, Figure 2 It is a cross-sectional schematic diagram of the atomizer seat 20 of the electronic atomizer assembly 1 provided by the present invention.

[0032] The electronic atomization assembly 1 includes a liquid storage tank 10, an atomization seat 20 and an atomization core 30. The electronic atomization assembly 1 can be used to atomize liquid and generate smoke for use in different fields, such as medical treatment, electronic cigarettes, etc. In a specific embodiment, the electronic atomization assembly 1 can be used in an electronic cigarette atomization device to atomize cigarette oil and generate smoke for inhalation by smokers, and the following embodiments are all taken as an example; of course, in other embodiments, the electronic atomization assembly 1 can also be applied to hair spray equipment to atomize hair spray for hair styling; or applied to medical equipment for treating upper and lower respiratory system diseases to atomize medical drugs.

[0033] The liquid storage tank 10 is sleeved on the atomizer seat 20 and is used to store the e-liquid. The liquid storage tank 10 can be made of other metals such as aluminum and stainless steel, as long as it can store the e-liquid without reacting with it to make it deteriorate; the shape and size of the liquid storage tank 10 are not limited and can be designed as needed.

[0034] The atomizer seat 20 includes an atomizer top seat 21 and an atomizer base 22. The atomizer seat 20 can be made of ceramic, stainless steel or other alloys, as long as it can play a supporting role; the shape and size of the atomizer seat 20 are not limited and can be designed as needed.

The atomizer core body 31 wraps the heating element. The atomizer core body 31 has a porous structure. The material of the atomizer core body 31 is a cotton core or porous ceramic. Since the atomizer core body 31 has a porous structure, the atomizer core body 31 can form a capillary effect. After the atomizer core body 31 contacts the smoke oil in the liquid storage tank 10, the smoke oil can reach the heating element inside the atomizer core body 31 through the atomizer core body 31, and then be atomized under the action of the heating element.

[0036] Among them, a first groove is provided on the atomizing base 22 to form the lower part of the atomizing chamber 221; a first through hole is provided on the bottom wall of the atomizing chamber 221 to form an air inlet channel 222; the air inlet channel 222 is connected to the atomizing chamber 221, so that the air inlet channel 222 is connected to the outside and the atomizing chamber 221. A second through hole and a third through hole are provided on the atomizing top seat 21 to form a first lower liquid channel 211 and a second lower liquid channel 212 respectively, so that the smoke oil in the liquid storage tank 10 enters the atomizing core 30 through the first lower liquid channel 211 and the second lower liquid channel 212, thereby realizing the atomization of the smoke oil. A fourth through hole is also provided on the atomizing top seat 21 to form the upper part of the atomizing chamber 221.

The air intake channel 40 connects the outside and the atomization chamber 221. The outside air enters the atomization chamber 221 through the air intake channel 222 to carry the smoke in the atomization chamber 221, and the smoke then passes through the air intake channel 40 to be inhaled by the user.

[0040] The surface of the atomizer seat 20 that contacts the atomizer core body 31 is provided with a micro-groove structure 23. Specifically, the micro-groove structure 23 can be provided on the atomizer top seat 21 and / or the atomizer base 22. The micro-groove structure 23 can play a role in draining the e-liquid, and can also fine-tune the amount of e-liquid entering the atomizer core 30.
