[0040] In the prior art, for liquid storage cotton type atomization device products, the aerosol matrix in the area of ​​the liquid storage cotton near the atomizer core mounting hole is easily absorbed and consumed by the atomizer core during operation, while the aerosol matrix in the area away from the atomizer core mounting hole is not easily absorbed, resulting in a large amount of aerosol matrix remaining in the liquid storage cotton, thereby reducing the utilization rate of the aerosol matrix. Based on this, an embodiment of the present application provides a liquid storage cotton that can solve the above problems. The liquid storage cotton provided in an embodiment of the present application will be described in detail below in conjunction with the accompanying drawings.

[0041] See Figures 1 to 3 As shown, the liquid storage cotton 10 provided in one embodiment of the present application includes a first cotton layer 100, a second cotton layer 200 arranged on the outer peripheral side of the first cotton layer 100, and a connecting layer 300 connected between the first cotton layer 100 and the second cotton layer 200, and the connecting layer 300 is constructed with a plurality of liquid guide holes 310 that pass through along the arrangement direction of the first cotton layer 100 and the second cotton layer 200. Taking the cross-section of the liquid storage cotton 10 as an example, the arrangement direction is radial.

[0042] Taking the first cotton layer 100 connected to a heating element (not shown) as an example, by providing a plurality of liquid guide holes 310 on the connecting layer 300 between the first cotton layer 100 and the second cotton layer 200, each liquid guide hole 310 will generate capillary force, thereby increasing the magnitude of the capillary force and improving the adsorption capacity and liquid guide capacity of the aerosol matrix of the second cotton layer 200. In this way, when the aerosol matrix in the first cotton layer 100 is consumed, under the action of the larger capillary force, the aerosol matrix stored in the second cotton layer 200 is more easily adsorbed into the first cotton layer 100, thereby being atomized and consumed by the heating element, so that the aerosol matrix in the periphery of the liquid storage cotton 10 can be fully utilized, greatly reducing the residual rate of the aerosol matrix in the liquid storage cotton 10 and improving the utilization rate of the aerosol matrix. At the same time, the provision of the connecting layer 300 also improves the connection tightness between the first cotton layer 100 and the second cotton layer 200.

[0043] In this embodiment, the cross-section of the liquid-storage cotton 10 is circular (the cross-section is perpendicular to the axial direction of the liquid-storage cotton 10). Correspondingly, the cross-sections of the first cotton layer 100, the second cotton layer 200, and the connecting layer 300 are also circular or annular for ease of processing. Of course, in other embodiments, the cross-section of the liquid-storage cotton can also be oval, rectangular, square, triangular, waist-shaped, or other irregular shapes.

[0044] like Figure 3 As shown, in one embodiment, multiple liquid guide holes 310 are arranged in an array. Since the liquid guide holes 310 are distributed relatively evenly, the aerosol matrix at multiple locations on the second cotton layer 200 can be adsorbed into the first cotton layer 100 under the capillary force of the liquid guide holes 310, and then can be atomized by the heating element, reducing the residual rate of the aerosol matrix. In other embodiments, the multiple liquid guide holes can also be arranged irregularly.

[0045] like Figure 3 As shown, in this embodiment, the hole shape of the liquid guide hole 310 is diamond-shaped. In other embodiments, the hole shape of the liquid guide hole can also be a regular shape such as a circle, square, triangle, or an irregular shape such as a teardrop shape or a wedge shape.

[0046] In one embodiment, the density of the first cotton layer 100 is greater than the density of the second cotton layer 200. The density ratio of the second cotton layer 200 to the first cotton layer 100 is in a range of 1:8 to 1:1.1. In this way, the density difference between the first cotton layer 100 and the second cotton layer 200 can be utilized to generate a gradient force, so that the aerosol matrix is ​​continuously transferred from the periphery of the liquid storage cotton 10, that is, the second cotton layer 200, to the center, that is, the first cotton layer, thereby improving the utilization rate of the aerosol matrix outside the liquid storage cotton 10.

[0047] In some embodiments, the surface energy of the first cotton layer 100 is greater than the surface energy of the second cotton layer 200. Specifically, the water contact angle of the first cotton layer 100 can be smaller than the water contact angle of the second cotton layer 200. This configuration creates a surface energy gradient along the arrangement direction of the first cotton layer 100 and the second cotton layer 200, allowing the aerosol matrix to continuously flow from the periphery to the center of the liquid-storage cotton 10, thereby reducing the residual rate of the aerosol matrix at the periphery of the liquid-storage cotton 10.

[0048] like Figure 3 As shown, in one embodiment, the axial dimension of the first cotton layer 100 is greater than the axial dimension of the second cotton layer 200, and the axial dimension of the connecting layer 300 is equal to the axial dimension of the second cotton layer 200. The axial direction is perpendicular to the arrangement direction of the first cotton layer 100 and the second cotton layer 200. Figure 3The axial direction is indicated by arrow Z. Since the heating element is closer to the first cotton layer 100, the height (i.e., the axial dimension) of the first cotton layer 100 is increased, while the height of the second cotton layer 200 is reduced. This achieves the purpose of increasing the volume of the first cotton layer 100 and reducing the volume of the second cotton layer 200. This shortens the transport path of the aerosol matrix, improves the transport efficiency of the aerosol matrix outside the liquid storage cotton 10, and reduces the residual liquid rate outside.

[0049] like Figure 3 As shown, in one embodiment, along the arrangement direction of the first cotton layer 100 and the second cotton layer 200, the thickness ratio of the second cotton layer 200 to the first cotton layer 100 can range from 7:1 to 1:7; further, the thickness ratio of the second cotton layer 200 to the first cotton layer 100 can range from 5:1 to 1:5. For example, Figure 3 In the illustrated embodiment, the thickness of the first cotton layer 100 is greater than the thickness of the second cotton layer 200, thereby reducing the transport path of the peripheral aerosol matrix to the center of the liquid storage cotton 10, making it easier for the aerosol matrix to be transferred to the first cotton layer 100, thereby reducing the peripheral residual liquid rate. In other embodiments, the thickness of the first cotton layer can also be less than the thickness of the second cotton layer.

[0050] like Figure 3 As shown, in one embodiment, the second cotton layer 200 is provided with a through hole 210 along its own axial direction, and the first cotton layer 100 is transitionally matched with the hole wall of the through hole 210, that is, the outer diameter of the first cotton layer 100 is the same as the aperture size of the through hole 210, or the outer diameter of the first cotton layer 100 is slightly larger than the aperture of the through hole 210, so that the connection between the two is relatively tight; it can also be that the outer diameter of the first cotton layer 100 is slightly smaller than the aperture of the through hole 210, and the outer diameter of the connecting layer 300 is adapted to the aperture of the through hole 210, that is, the same, thereby facilitating the assembly of the second cotton layer 200, the connecting layer 300 and the first cotton layer 100. In this way, the second cotton layer 200 and the first cotton layer 100 can change their materials and structures according to actual needs, and can be easily and quickly assembled and replaced, realizing the controllable utilization rate of the material, structure and aerosol matrix of the liquid storage cotton 10, while reducing the research and development cost of the liquid storage cotton 10 and shortening the research and development cycle.

[0051] like Figure 1 and Figure 2 As shown, in one embodiment, the first cotton layer 100 is provided with an atomization mounting hole 110 along its axial direction for mounting a heating element; the first cotton layer 100 and the second cotton layer 200 are arranged concentrically with the atomization mounting hole 110. This ensures that each position of the first cotton layer 100 is at the same distance from the heating element, and each position of the second cotton layer 200 is at the same distance from the first cotton layer 100, resulting in a more consistent atomization effect at each position and reducing the residual rate of aerosol matrix at each position.

[0052] In one embodiment, both the second cotton layer 200 and the first cotton layer 100 are composed of a plurality of cotton fibers, each of which includes at least one fiber component. Furthermore, the surface energy of the fiber components of the first cotton layer 100 differs from the surface energy of the fiber components of the second cotton layer 200. Specifically, the surface energy of the fiber components of the first cotton layer 100 is greater than the surface energy of the fiber components of the second cotton layer 200. This creates an energy gradient between the two, facilitating the transfer of peripheral aerosol matrix to the first cotton layer and reducing the aerosol matrix residue rate.

[0053] The second cotton layer 200 and the first cotton layer 100 may be monocomponent cotton fibers, whose fiber components may be one of polyester (PET), polypropylene (PP), polyethylene (PE), and polyamide (PA). The second cotton layer 200 and the first cotton layer 100 may also be bicomponent cotton fibers, whose cotton fibers may include at least one of polyester (PET), polypropylene (PP), polyethylene (PE), and polyamide (PA). For example, the cotton fibers may be a combination of polyester and polyester fibers, or a combination of polyamide and polyester fibers. Both polyamide and polyester fibers have strong adsorption properties for aerosol matrices, resulting in excellent liquid storage capacity for the liquid storage cotton 10. The connecting layer 300 may be a spunlace fabric, specifically including cellulose fibers such as cotton, linen, viscose, and Tencel.

[0054] like Figure 4 As shown, in one embodiment, the second cotton layer 200 is taken as a two-component cotton fiber as an example, that is, the second cotton layer 200 includes two fiber components, and the surface energy of the two fiber components is the same, that is, the two can be made of the same material, for example, the cotton fiber is a combination of polyester fiber and polyester fiber; the two fiber components can be different, for example, a combination of polyamide fiber and polyester fiber, of course, it is not limited to this.

[0055] The two fiber components can be combined using methods commonly used in the art, such as integrated filament formation. For example, the first fiber component 120 and the second fiber component 130 are passed through a composite spinning assembly for spinning, and then ejected from the composite spinneret to obtain composite fiber precursors; the composite fiber precursors are then post-processed to obtain composite cotton fibers. Alternatively, short fiber carding, needle punching, and hot air forming can be used. It is understood that the first cotton layer 100 can also include two fiber components, and the materials of the two fiber components can be the same or different.

[0056] like Figure 4 As shown, in one embodiment, the two fiber components are respectively named as the first fiber component 120 and the second fiber component 130, and the first fiber component 120 and the second fiber component 130 divide the cross section of the second cotton layer 200 (or the first cotton layer 100) into two parts. Figure 4In the embodiment shown, the first fiber component 120 and the second fiber component 130 are arranged in a core-skin structure, that is, the first fiber component 120 and the second fiber component 130 are concentrically arranged. Figure 5 As shown, the first fiber component 120 and the second fiber component 130 are distributed in an eccentric structure, that is, the first fiber component 120 and the second fiber component 130 can also be eccentrically arranged.

[0057] In another embodiment, the first fiber component 120 and the second fiber component 130 are arranged in a parallel structure, such as Figure 6 As shown, the first fiber component 120 and the second fiber component 130 are arranged side by side. The area ratios of the first fiber component 120 and the second fiber component 130 can be the same, that is, the first fiber component 120 and the second fiber component 130 are semicircular, forming a circular cross section. Of course, the area ratios of the first fiber component 120 and the second fiber component 130 can also be different, for example Figure 7 As shown, the cross section of the first fiber component 120 is a major arc, and the cross section of the second fiber component 130 is a minor arc.

[0058] like Figure 8 As shown, in one embodiment, the first fiber component 120 and the second fiber component 130 are distributed in an orange segment structure, that is, the first fiber component 120 and the second fiber component 130 divide the cross section of the first cotton layer 100 into multiple parts; wherein, the first fiber component 120 and the second fiber component 130 are alternately arranged along the circumference of the liquid storage cotton 10. Specifically, Figure 8 In the embodiment, the cross section is divided into eight parts by the first fiber component 120 and the second fiber component 130, presenting an orange segment structure. It can be understood that Figure 8 This is just an example, but it is not limited to this. For example, the number of petals can also be four petals, sixteen petals, etc. In another embodiment, Figure 9 As shown, the first fiber component 120 and the second fiber component 130 may also be randomly arranged to present an island-in-the-sea structure.

[0059] The above-mentioned liquid storage cotton 10, through the aforementioned design, can greatly improve the utilization rate of the aerosol matrix around the liquid storage cotton 10, and can freely change the materials and structures of the first cotton layer 100 and the second cotton layer 200, so that the liquid storage cotton 10 can achieve structure and material replacement and assembly in a short time, and realize the controllable utilization rate of the material, structure and aerosol matrix of the liquid storage cotton 10, while reducing the research and development cost of the liquid storage cotton 10 and shortening the research and development cycle.

[0060] Furthermore, the present application also provides an atomizer (not shown) comprising a heating element (not shown) and the liquid storage cotton 10 described above. The heating element is used to atomize the aerosol matrix in the liquid storage cotton. The heating element is disposed within the first cotton layer 100 and corresponds to the position of the second cotton layer 200. Taking the second cotton layer 200 as an example, which is cylindrical, the heating element and the second cotton layer 200 are arranged radially along the second cotton layer 200. It is understood that the atomizer may also include other commonly used components in the art, which will not be described in detail here.

[0061] Furthermore, the present application also provides an atomizer device (not shown) comprising a power supply assembly (not shown) and the aforementioned atomizer, the power supply assembly being used to power the heating element. Because the atomizer device includes the liquid storage cotton of the aforementioned embodiment, it can improve the utilization rate of the aerosol matrix, resulting in slower flavor decay and better taste consistency in the atomizer device, thereby enhancing the user experience.

[0062] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0063] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
