An atomizer converts solutions such as oil into small droplets through heating for users to inhale. Atomizers can be used in medical, daily life and other fields. In related technologies, a cotton wick is usually provided inside the atomizer. , oil chamber and heating structure, the oil in the oil chamber flows directly to the cotton core, and the heating structure heats the cotton core, so that the oil in the cotton core is atomized to form small oil droplets and are transported to the user along with the air flow. When the remaining amount of oil in the oil chamber is insufficient, during the use of the atomizer, due to vibration, temperature difference, air pressure changes and other factors, the oil flowing to the cotton core will flow too fast, which will cause the heating structure to be unable to heat the cotton core. Forming an effective heating atomization effect, part of the oil has no time to be atomized by the heating structure and will overflow from the inside of the cotton core and reach the atomization channel. Large oil droplets in the atomization channel will cause oil leakage problems, and the air flow will When passing through these large oil droplets, a "gurgling" noise will be produced, which affects the user experience.

Based on this, with reference to Figures 1 to 8, embodiments of the present invention provide an atomization core assembly and an electronic atomizer. An oil supply cotton 130 is provided to supply oil to the oil storage cotton 150, and an oil outlet forming a height difference is provided. The hole 141 and the oil inlet hole 111 can effectively control the speed of oil delivery to the oil storage cotton 150, and can effectively improve the atomization effect.

Referring to Figures 1 to 4, an atomization core assembly according to the first embodiment of the present invention includes an outer tube body 110, a top cover 120, an oil supply cotton 130, an inner tube body 140, an oil storage cotton 150 and a heating element 160 : The outer tube body 110 is provided with an oil inlet hole 111, which is used to supply oil; the top cover 120 is connected to the top of the outer tube body 110, and the top cover 120 is provided with a smoke channel 121, which is used to output mist. The oil supply cotton 130 is arranged in the outer tube body 110. The oil supply cotton 130 is provided with an oil supply channel 131. The oil inlet hole 111 is located at the outer bottom of the oil supply cotton 130. The oil reaches the oil supply from the oil inlet hole 111. The outer bottom of the surface, optionally, the oil supply cotton 130 is an integrated cotton; the inner tube body 140 is located in the oil supply channel 131, and the oil supply cotton 130 is filled in the space formed between the inner tube body 140 and the outer tube body 110, so that Ensure that the oil can only be transported to the oil storage cotton 150 through the oil supply cotton 130. The inner tube body 140 is provided with an oil outlet hole 141. The oil outlet hole 141 is located at the inner top of the oil supply cotton 130. The oil outlet hole 141 and the oil inlet hole 111 is located on the inner and outer sides of the oil supply cotton 130, and the oil outlet hole 141 is located above the oil inlet hole 111, so that the oil can be transported from bottom to top, thereby ensuring that the oil is transported in the bottom-to-top direction after entering the oil supply cotton 130 along the outside. To reach the oil outlet 141, the gravity of the oil can be used to effectively reduce the flow rate of oil transportation, and can effectively ensure that the oil flow path is long enough, thereby providing a controllable and stable oil supply effect for subsequent atomization work; storage The oil cotton 150 is arranged in the inner tube body 140. The oil storage cotton 150 is provided with an atomization channel 151. The oil outlet 141 is located outside the oil storage cotton 150.

The heating element 160 is used to heat and atomize the oil that reaches the inner wall area of the oil storage cotton 150.

The oil is transported to the oil storage cotton 150 through the oil supply cotton 130. The oil is transported from the oil inlet hole 111 to the oil supply cotton 130, and the oil is transported by capillary action in the oil supply cotton 130. The oil is transported by capillary action instead of conventional flow. The speed at which the oil is transported in the oil supply cotton 130 can be effectively controlled, and the oil outlet hole 141 is located above the oil inlet hole 111. Through the action of the oil's own gravity, the speed at which the oil is transported in the oil supply cotton 130 can be further reduced, thus This prevents incomplete atomization caused by excessive flow of oil to the oil storage cotton 150, thereby effectively reducing oil spillage into the atomization channel 151 to form large oil droplets due to incomplete atomization, and ultimately preventing large particles.

The problem of oil overflow occurs due to completely atomized oil, which can further improve the atomization effect of the overall structure.

The deformation avoidance seam 132 can enable the oil supply cotton 130 to form a good deformation adaptability. The blocking portion 152 of the oil storage cotton 150 passes through the blocking position. The groove 142 then reaches the outside of the inner tube body 140 and is inserted into the deformation avoidance slit 132. Due to the effect of the deformation avoidance slit 132, the oil supply cotton 130 can effectively clamp the clamping portion 152, thereby effectively improving the firmness of the overall structure. sex.

It can be understood that the length of the oil storage cotton 150 is less than the length of the oil supply cotton 130, that is, the height of the oil storage cotton 150 is less than the height of the oil supply cotton 130. By setting the volume of the oil supply cotton 130 to be significantly larger than the volume of the oil storage cotton 150 , after the heating element 160 heats and atomizes the oil in the oil storage cotton 150 to cause oil consumption, it can ensure that the oil supply cotton 130 can provide sufficient oil for the oil storage cotton 150 in a timely manner, thereby preventing the oil storage cotton 150 from being damaged due to insufficient oil. Affects the stability of atomization.
