The present application claims the benefit of Chinese Patent Application No. 2023226105220 filed on Sep. 22, 2023, the contents of which are incorporated herein by reference in their entirety.
The present invention relates to the field of atomization technology, and more specifically, to an atomization device and atomization core thereof.
Electronic atomization device is a kind of device that uses electric energy to heat liquid, so that liquid reaches boiling point and changes into steam, which is widely used in electronic cigarettes and medical cosmetology fields.
The electronic atomization device comprises an atomizer, the core of which is the atomization core. The atomization core typically includes a liquid conducting member 100 and a heating element 200 that are being assembled together. Porous ceramic and other types of rigid liquid-conducting materials are widely used due to their ease of assembly. The liquid conducting member 100 is usually a bulk structure that typically injects oil from the side (see number 101 or number 102), while the bottom surface (i.e. atomization surface) is provided with the heating element 200 for heating and atomizing the atomizing liquid.
Due to the fact that the aerosol formed by heating and atomization is expelled from the circumferential side of the liquid conducting member to the outside of the atomizer for the consumer to inhale, the long path of aerosol flow may alter the taste of aerosol due to cooling, and some of the aerosol may condense, leading to inconsistent atomization taste and potential health issues from inhaling condensed liquid. At the same time, the vertically placed liquid conducting member 100, which injects oil from the side, has the problem of easy oil leakage.
The technical problem to be solved by the present invention is to provide an atomization device and atomization core thereof.
The technical solution adopted by the present invention to solve its technical problem is to construct an atomization core comprising a liquid conducting member and a heating element, the liquid conducting member is provided with an airflow hole longitudinally running through itself, and the liquid conducting member is also provided with at least one liquid storage groove, the liquid storage groove is arranged on the outer periphery of the airflow hole, the liquid storage groove comprises at least one first sub-liquid storage groove and at least one second sub-liquid storage groove, the first sub-liquid storage groove is in communication with the second sub-liquid storage groove;
In some embodiments, the depth of the first sub-liquid storage groove is smaller than the depth of the second sub-liquid storage groove, and the longitudinal cross-sectional width of the first sub-liquid storage groove is equal to the longitudinal cross-sectional width of the second sub-liquid storage groove.
In some embodiments, the depth of the first sub-liquid storage groove is less than the depth of the second sub-liquid storage groove, and the longitudinal cross-sectional width of the first sub-liquid storage groove is greater than the longitudinal cross-sectional width of the second sub-liquid storage groove.
In some embodiments, the liquid storage groove comprises two first sub-liquid storage grooves and a second sub-liquid storage groove, and the two ends of the second sub-liquid storage groove are respectively connected and in communication with the two first sub-liquid storage grooves.
In some embodiments, the number of liquid storage groove is at least two, and the at least two liquid storage grooves are spaced apart on the outer periphery of the airflow hole.
In some embodiments, the wall surface of the airflow hole which is opposite to the second sub-liquid guide groove is curved or flat.
In some embodiments, the heating element comprises a heating portion and at least two electrode portions connected to the heating portion, the heating portion is attached on or embedded in the atomization surface, and the ends of at least two electrode portions are attached on or embedded in the liquid conducting member.
In some embodiments, the bottom of the liquid conducting member is further provided with a receiving groove.
In some embodiments, the width of the receiving groove is 0.1-0.8 mm.
In some embodiments, the cross-section of the receiving groove is in the shape of a C-shaped structure, a U-shaped structure, or a straight shaped structure.
In some embodiments, the liquid conducting member is at least one of porous ceramics, foamed metals, and porous glass.
The present invention also constructs an atomization device, characterized by comprising an atomization core according to any one of the above embodiments.

The airflow hole is located at the center of the liquid conducting member, which can be close to the outlet of the atomization device, the aerosol generated by the atomization core has a shorter flow path and is less prone to affect the taste due to cooling, and its taste is closer to the original taste of the atomizing liquid, and it can effectively prevent the aerosol from condensing due to cooling during the flow process. It can also prevent the generated condensate from following the aerosol flow and being sucked by consumers, and can avoid damage to the atomization device caused by the condensate, thus effectively improving the service life of the atomization device. And the liquid conducting member injects liquid from the top, which is less prone to oil and liquid leakage compared to injecting liquid from the side.

Please refer to
The wall surface of the airflow hole 111 which is opposite to the second sub-liquid storage groove 1122 forms an atomization surface A, and the heating element 12 is located on the atomization surface A.
Understandably, the airflow hole 111 is located at the center of the liquid conducting member 11, which can be close to the outlet of the atomization device, the aerosol generated by the atomization core 10 has a shorter flow path and is less prone to affect the taste due to cooling, and its taste is closer to the original taste of the atomizing liquid, and it can effectively prevent the aerosol from condensing due to cooling during the flow process. It can also prevent the generated condensate from following the aerosol flow and being sucked by consumers, and can avoid damage to the atomization device caused by the condensate, thus effectively improving the service life of the atomization device.
In addition, the heating element 12 is mainly arranged on a wall surface of the airflow hole 111 which is opposite to the second sub-liquid storage groove 1122, the heating clement 12 mainly heats and atomizes the atomizing liquid in the second sub-liquid storage groove 1122, so that the atomizing liquid in the liquid storage cavity of the atomization device can first pass through the first sub-liquid storage groove 1121 and then enter the second sub-liquid storage groove 1122. When the atomizing liquid in the second sub-liquid storage groove 1122 is consumed, the atomizing liquid in the first sub-liquid storage groove 1121 will be replenished to the second sub-liquid storage groove 1122, making the liquid supply smooth and less prone to oil leakage and seepage.
Specifically, the liquid conducting member 11 is roughly a square structure with an upper surface and a lower surface arranged in opposition. The liquid storage groove 112 is formed by a concave groove on the upper surface extending toward the lower surface, which is a groove structure that do not run through the liquid conducting member 31.
Referring to
In some embodiments, the depth of the first sub-liquid storage groove 1121 is less than the depth of the second sub-liquid storage groove 1122, and the longitudinal cross-sectional width of the first sub-liquid storage groove 1121 is greater than that of the second sub-liquid storage groove 1122.
In some embodiments, as shown in
In some embodiments, as shown in
In some embodiments, the wall surface of the airflow hole 111 which is opposite to the second sub-liquid storage groove 1122 is curved or flat, that is, the atomization surface A can be a curved structure (as shown in
In some embodiments, the bottom of the liquid conducting member 11 is further provided with a receiving groove 113. The width of the receiving groove 113 is 0.1-0.8 mm. Preferably, the cross-section of the receiving groove 113 is in the shape of a C-shaped structure, a U-shaped structure, or a straight shaped structure, and its structure and size can be selected and set according to actual needs, without specific limitations here.
Specifically, the receiving groove 113 avoids the aforementioned liquid storage groove 112 and avoids direct communication with the liquid storage groove 112. The receiving groove 113 can be designed with an opening facing downwards, and its slot width can be 0.1-0.8 mm, for example, it can be selected as 0.1 mm, 0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm. The slot depth of the receiving groove 113 can be 0.5 mm-2 mm, etc., such as 0.5 mm, 1 mm, 1.5 mm, 2 mm.
It can be understood that in some special environments, such as when the external atmospheric pressure is low, due to the pressure of the atomization device being higher than the external atmospheric pressure, that is, there is a pressure difference between the two, the gas inside the atomization device may expand, causing some of the atomizing liquid in the liquid conducting member 11 to be squeezed out of the liquid conducting member 11. The inner cavity of the receiving groove 113 can form a containment space to absorb this part of the atomizing liquid, and due to the narrow groove width of the receiving groove 313, the atomizing liquid can keep in the receiving groove 313 through its own capillary tension, and won't drip out of the liquid conducting member 11, which can achieve a good effect of preventing oil leak and liquid leak.
In some embodiments, the heating element 12 may include a heating portion 121 and at least two electrode portions 122 connected to the heating portion 121. The heating portion 121 is attached on or embedded in the atomization surface 1122a, and the ends of the at least two electrode portions 122 are attached on or embedded in the liquid conducting member 11. Preferably, the heating element 12 is a planar structure, which is relatively flat and not easily deformed, and the combination processing with the liquid conducting member 11 is simpler. In addition, when the end of the electrode portion 122 is embedded on the bottom of the liquid conducting member 11, it can avoid unstable circuit contact caused by pulling or other factors, and improve the stability of the atomizer operation.
In some embodiments, the liquid conducting member 11 is at least one of porous ceramics, foamed metals, or porous glass. Specifically, the liquid conducting member 11 can be made from porous ceramics. It can be understood that the material used to produce the liquid conducting member 11 can also be porous materials with microporous capillary effects, such as foam metal, porous glass, or hard glass fiber tubes.
After the heating element 12 is powered on, it heats the atomizing liquid stored in the second sub-liquid guide groove 1122, thereby generating aerosols that can be directly aspirated by the user. The heating portion 121 can be a sheet-like heating mesh, which is attached and fixed to the atomization surface A. The heating portion 121 can be a disc-shaped heating wire that is bent or a grid shaped heating sheet. The heating portion 121 can be sintered into an integrated structure with the liquid conducting member 31 to adhere to the atomization surface A. In some embodiments, the above-mentioned heating portion 121 may also be a heating circuit, heating trajectory, heating coating or heating film formed on the atomization surface A. Its structural and shape can be diverse and can be selected according to needs. The above-mentioned heating mesh, heating wire, heating sheet, heating circuit, heating trajectory, heating coating or heating film are correspondingly set with the second sub-liquid guide groove 1122, so that the distance between the second sub-liquid guide groove 1122 and the heating portion 121 is the closest, which is used for atomizing liquids such as smoke and oil to quickly reach the heating portion 121 for atomization. The electrode portion 122 mentioned above can be a sheet-like structure or a columnar or rod-shaped structure.
Preferably, the material of the heating element 12 can be a metal material, metal alloy, graphite, carbon, conductive ceramic, or a composite material of other ceramic materials and metal materials with appropriate impedance. Metal or alloy materials with appropriate impedance include at least one of nickel, cobalt, zirconium, titanium, nickel alloys, cobalt alloys, zirconium alloys, titanium alloys, nickel chromium alloys, nickel iron alloys, iron chromium alloys, iron chromium aluminum alloys, titanium alloys, iron manganese aluminum based alloys, and stainless steel.
