[0026] Referring to "embodiments" herein means that specific features, structures, or characteristics described in connection with the embodiments can be included in at least one embodiment of the present application. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments

[0027] In related existing cartridges, the cartridge includes an oil storage chamber and an atomization core; the atomization core is disposed in the oil storage chamber, and the atomization core is used to atomize the e-liquid in the oil storage chamber to generate smoke for the user to inhale. However, the effect of conducting e-liquid in the connection between the atomization core and the oil storage chamber is not good, so that the atomization core is prone to burn, or too much e-liquid is conducted to cause oil leakage, and the user experience is very poor.

[0028] Based on this, an embodiment of the present application provides an atomization core. As Figures 1 to 2 shown, the atomization core 1000 includes: an inner tube 500, and an outer tube 100 sleeved around the outer circumference of the inner tube 500; at least two first oil passage grooves 1001 penetrating through the tube core are provided on the outer tube 100, and at least two second oil passage grooves 5001 penetrating through the tube core are provided on the inner tube 500, and the first oil passage grooves 1001 and the second oil passage grooves 5001 are arranged in alignment; a heating mesh 400 for atomizing the e-liquid flowing out through the first oil passage grooves 1001 and the second oil passage grooves 5001 is arranged in the inner cavity of the inner tube 500 to form smoke for the user to inhale; an outer cotton 200 is arranged between the outer tube 100 and the inner tube 500, and the outer cotton 200 is an integrally formed tubular cotton, and the inner diameter of the tubular cotton matches the outer diameter of the inner tube 500. When the tubular cotton is inserted outside the inner tube 500, the tubular cotton abuts against the first oil passage grooves 1001 and the second oil passage grooves 5001. Therefore, the e-liquid passes through the first oil passage grooves 1001 to reach the tubular cotton, and the e-liquid of the tubular cotton then enters the heating mesh 400 through the second oil passage grooves 5001, and is atomized by the heating mesh 400 to obtain smoke for the user to inhale.

[0029] In this embodiment, an inner cotton 300 is arranged between the inner tube 500 and the heating mesh 400, and the inner cotton 300 is used to store the amount of e-liquid for the heating mesh 400 to atomize to form smoke. The inner cotton 300 can also store some amount of e-liquid, and the inner cotton 300 is closely attached to the heating mesh 400. Therefore, the effect of the heating mesh 400 atomizing e-liquid is better.

[0030] In this embodiment, the outer cotton 200 and the inner cotton 300 are connected through the second oil passage grooves 5001. When the outer cotton 200 absorbs e-liquid, it conducts the e-liquid to the inner cotton 300 and conducts it through the second oil passage grooves 5001, so that the flow of e-liquid is correspondingly controlled, preventing the problem of oil leakage caused by too much e-liquid, and at the same time preventing the problem of burning caused by too little e-liquid.

[0031] As Figure 1As shown, in this embodiment, when the inner cotton 300 is projected on the axis of the atomization core 1000, the bottom end of the inner cotton 300 is lower than the bottom end of the second oil passage groove 5001, and the top end of the inner cotton 300 is lower than the top end of the second oil passage groove 5001. The bottom end of the inner cotton 300 being lower than the bottom end of the second oil passage groove 5001 means that the bottom end of the inner cotton 300 covers the bottom end of the second oil passage groove 5001, which can prevent the e-liquid from flowing downward too fast under the action of gravity and causing the problem of e-liquid leakage; the top end of the inner cotton 300 is lower than the top end of the first oil passage groove 1001. Therefore, the supplied e-liquid in the first oil passage groove 1001 is sufficient for the inner cotton 300 to absorb and atomize, preventing the phenomenon of burning due to insufficient e-liquid supply.

[0032] As Figure 2 shown, in this embodiment, the atomization core 1000 further includes a base 600. The outer tube 100 is in interference fit with the base 600, and the base 600 and the inner tube 500 are integrally formed. Therefore, the fitting connection between the outer tube 100 and the inner tube 500 is the fitting connection between the base 600 and the outer tube 100, which can save costs and improve production efficiency.

[0033] As Figure 2 shown, in this embodiment, a lead wire 800 is provided at one end of the heating mesh 400. The lead wire 800 is used to connect to an external power supply to ensure the stability of the electrical connection.

[0034] As Figure 2 shown, in this embodiment, the atomization core 1000 further includes a bracket disposed inside the base 600 for clamping the lead wire 800 to prevent the short-circuit phenomenon caused by the positive and negative poles of the lead wire 800 being connected. A relief groove 7001 is provided on the outer peripheral surface of the bracket, and the lead wire 800 is placed in the relief groove 7001 to avoid the short-circuit phenomenon caused by the positive and negative lead wires 800 loosening and connecting.

[0035] As Figure 3 shown, the present application also provides a preparation method for the atomization core 1000, and the preparation method includes:

[0036] S1, the inner cotton 300 is wound around the heating mesh 400 closely for at least one week to form a first component;

[0037] S2, the first component is inserted into the cavity of the inner tube 500 along the direction of the opening groove 5002 and is in interference fit with the inner wall of the inner tube 500 to form a second component; inserting along the direction of the opening groove 5002 into the inner tube 500 makes the assembly more convenient and improves the efficiency.

[0038] S3, an outer cotton 200 is tightly sleeved outside the second component to form a third component; the diameter of the outer cotton 200 is adapted to the outer diameter of the second component, so that the outer cotton 200 is tightly sleeved outside the second component, and the assembly efficiency is high.

[0039] S4. The third component is inserted into the inner cavity of the outer tube 100 to form the fourth component; that is, the outer tube 100 is sleeved outside the outer cotton 200. Since the outer cotton 200 is tubular cotton, when assembling the outer tube 100, the outer cotton 200 will not have wrinkling or local wrinkling phenomena.

[0040] S5. One end of the fourth component is provided with a bracket, and the bracket is inserted into the inner tube 500 and is in interference fit with the inner tube 500 to form the atomization core 1000.

[0041] In the preparation method provided by this embodiment, since the outer cotton 200 is tubular cotton, it not only provides convenient and fast assembly, improves production efficiency, but also can reduce costs.

[0042] The above is only the implementation mode of this application, and does not limit the patent scope of this application. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of this application, or directly or indirectly applied in other related technical fields, shall be included in the patent protection scope of this application by the same token.
