[0033] It can be understood that the liquid guide member 10 provided in the present application is installed in the atomizer core 20 for use. The atomizer core 20 generally also includes a fixed cylinder 21 and a heating mesh 22, and the liquid guide member 10 is located between the fixed cylinder 21 and the heating mesh 22. The liquid guide member 10 includes a heat-resistant layer 11, a protective layer 12 and a liquid guide layer 13. The heat-resistant layer 11, the liquid guide layer 13 and the protective layer 12 are stacked together in sequence, and all have an adsorption and guiding effect on the liquid aerosol generating medium. The heat-resistant layer 11 is arranged in affixed relation with the heating mesh 22, that is, the heat-resistant layer 11 maintains a complete fit with the heating mesh 22 or a small gap, and the heat-resistant layer 11 has better heat resistance, which is used to enhance the heat resistance of the liquid guide member 10, and effectively prevent the liquid guide member 10 from producing odor when the heating mesh 22 is heated at a high temperature; the protective layer 12 is arranged in affixed relation with the inner wall of the fixed cylinder 21. That is, the protective layer 12 maintains a complete fit with the fixed cylinder 21 or a small gap. The protective layer 12 is used to protect the liquid guide 10, and has good reliability, which prevents the liquid guide 10 from being damaged when it is installed into the fixed cylinder 21. The liquid guide layer 13 is located between the heat-resistant layer 11 and the protective layer 12, and has better liquid guiding performance. It absorbs and stores the aerosol generating medium and guides the aerosol generating medium to the heating mesh 22. The liquid guide 10 is composed of different functional layer structures, so that the liquid guide 10 takes into account both heat resistance and reliability, and has good adsorption of the aerosol generating medium, effectively preventing the liquid guide 10 from generating odor during the high-temperature heating process of the heating mesh 22 when the atomizing core 20 is used, ensuring the user's taste, and also preventing the liquid guide 10 from being damaged when it is installed into the fixed cylinder 21. The heat-resistant layer 11, the liquid-conducting layer 13 and the protective layer 12 can be made of fiber materials with different characteristics in heat resistance, water absorption, softness, etc., for example: cotton fiber, linen fiber, etc. In terms of material selection, the heat-resistant layer 11 focuses on heat resistance, the liquid-conducting layer 13 focuses on adsorption and guiding effects, and the protective layer 12 focuses on reliability, so that the liquid-conducting component 10 takes into account both heat resistance and reliability, and has good adsorption for aerosol generating media.

[0034] Please continue to refer to Figure 1 , Figure 2 and Figure 3 In some embodiments, the heat-resistant layer 11 includes at least one layer of linen fiber and cotton fiber blended non-woven fabric 14 or linen fiber non-woven fabric 15; the liquid-conducting layer 13 includes at least one layer of linen fiber and cotton fiber blended non-woven fabric 14 or cotton fiber non-woven fabric 16; and the protective layer 12 includes at least one layer of cotton fiber non-woven fabric 16.

[0035] It can be understood that the heat-resistant layer 11 can be made of at least one layer of linen fiber and cotton fiber blended non-woven fabric 14 or linen fiber non-woven fabric 15, preferably linen fiber non-woven fabric 15, and the specific specification can be 75g / m 2 or 100g / m 2The liquid conducting layer 13 can be made of at least one layer of linen fiber and cotton fiber blended nonwoven fabric 14 or cotton fiber nonwoven fabric 16, preferably cotton fiber nonwoven fabric 16, and the specific specification can be 60g / m 2 The protective layer 12 can be made of at least one layer of cotton fiber non-woven fabric 16, and the specific specification can be 75g / m 2 .

[0036] There are differences between cotton fiber materials and linen fiber materials in characteristics such as heat resistance, water absorption, drainage, air permeability, softness and cost; among them, the heat resistance of linen fiber is better than that of cotton fiber. Compared with the liquid-conducting cotton used in the existing atomization core 20, which produces a burnt smell when heated at high temperature by the heating mesh 22, the heat-resistant layer 11 can be made of linen fiber or a blend of linen fiber and cotton fiber, so that the heat-resistant layer 11 has better heat resistance, effectively preventing the heat-resistant layer 11 from producing odor when heated at high temperature by the heating mesh 22, thereby ensuring the user's taste.

[0037] Water absorption refers to the property of a material to absorb water in water, and cotton fiber has better water absorption performance than flax fiber. The liquid conducting layer 13 is made of a blend of flax fiber and cotton fiber or cotton fiber, and the protective layer 12 is made of cotton fiber, so that the liquid conducting layer 13 and the protective layer 12 have an adsorption and guiding effect on the liquid aerosol generating medium, thereby improving the liquid conducting efficiency of the liquid conducting member 10 and the protective layer 12.

[0038] Drainage refers to the ability to absorb moisture and dry quickly, and the drainage performance of flax fiber is better than that of cotton fiber. The heat-resistant layer 11 is made of flax fiber or a blend of flax fiber and cotton fiber, which helps the aerosol generating medium to diffuse quickly to the heating mesh 22 and helps the atomization heating process of the heating mesh 22.

[0039] Air permeability refers to the permeability of gas to polymer materials such as films, coatings, and fabrics. Flax fibers are hollow, and air and moisture can circulate easily. The air permeability of flax fibers is better than that of cotton fibers. The heat-resistant layer 11 is made of flax fibers or a blend of flax fibers and cotton fibers. Since the heating mesh 22 is in contact with the heat-resistant layer 11 or maintains a small gap, it is beneficial to the diffusion of aerosol generated by atomization, thereby improving the atomization effect, and is beneficial to reducing the erosion of the heating mesh 22 by the aerosol, thereby extending the life of the heating mesh 22.

[0040] Cotton fiber is softer than flax fiber; the protective layer 12 is made of cotton fiber, so that the oil guide member can be easily accommodated in the fixed cylinder 21, and avoids damage to the oil guide member when entering the fixed cylinder 21. The cost of flax fiber is higher than that of cotton fiber. The heat-resistant layer 11 is made of a blend of flax fiber and cotton fiber, the liquid-conducting layer 13 is made of a blend of flax fiber and cotton fiber, and the protective layer 12 is made of cotton fiber, which is conducive to reducing costs.

[0045] See also Figure 6 In some embodiments, the heat-resistant layer 11 includes three layers of linen fiber and cotton fiber blended non-woven fabric 14 or linen fiber non-woven fabric 15; the liquid-conducting layer 13 includes five layers of linen fiber and cotton fiber blended non-woven fabric 14 or cotton fiber non-woven fabric 16; and the protective layer 12 includes three layers of cotton fiber non-woven fabric 16.

[0047] In some embodiments, the texture of the cotton fiber nonwoven fabric 16 in the protective layer 12 is vertical stripes.

[0048] It can be understood that the vertical lines are specifically arranged roughly along the extension direction of the inner hole of the fixed tube 21. Setting the texture of the protective layer 12 as vertical lines is conducive to the installation of the protective layer 12 into the fixed tube 21, so that the liquid guiding component 10 can be more easily accommodated in the fixed tube 21, and effectively avoid damage to the liquid guiding component 10 when entering the fixed tube 21.

[0050] It can be understood that the transverse stripes are specifically arranged roughly perpendicular to the extension direction of the inner hole of the fixed cylinder 21. Setting the texture of the liquid-conducting layer 13 as transverse stripes is beneficial to enhancing the reliability of the liquid-conducting layer 13 between the protective layer 12 and the heat-resistant layer 11, thereby enhancing the stability of the overall structure of the liquid-conducting part 10.

[0051] In some embodiments, the texture of the flax fiber and cotton fiber blended non-woven fabric 14 or the flax fiber non-woven fabric 15 in the heat-resistant layer 11 is horizontal stripes.
