Description

Technical Field

[0001] This application belongs to the technical field of liquid storage cotton, and more specifically, relates to a liquid storage cotton and an electronic atomizer. Background Art

[0002] The electronic atomizer is the core component of an electronic cigarette, and the liquid storage cotton is one of the important components of the electronic atomizer. The main function of the liquid storage cotton is to store the aerosol matrix. The liquid storage capacity and liquid locking capacity of the liquid storage cotton are closely related to the service life of the liquid storage cotton and the taste of the electronic cigarette when used. The stronger the liquid storage capacity and liquid locking capacity of the liquid storage cotton, the less frequently the liquid storage cotton needs to be replaced or the aerosol matrix needs to be refilled. The larger the amount of smoke of the electronic cigarette, the better the smoking taste for users.

[0003] Existing liquid storage cotton mainly uses polypropylene + polyethylene materials, or polyethylene terephthalate materials, or polyamide + polyethylene terephthalate materials. After testing, the oil storage capacity of the liquid storage cotton using polyamide + polyethylene terephthalate materials is about 15 grams of aerosol matrix stored per gram of liquid storage cotton, but this oil storage capacity has not yet met the existing requirements. This results in the need to frequently replace the liquid storage cotton or refill the aerosol matrix, leading to low utilization rate of the aerosol matrix. Utility Model Content

[0004] The purpose of the embodiments of this application is to provide a liquid storage cotton and an electronic atomizer to solve the technical problem of low utilization rate of the aerosol matrix of the current liquid storage cotton.

[0005] To achieve the above purpose, in the first aspect of the embodiments of this application, a liquid storage cotton is provided. The liquid storage cotton is provided with at least two mounting holes for mounting an atomization core;

[0006] The liquid storage cotton includes a first liquid storage part and a second liquid storage part. The first liquid storage part covers at least part of the second liquid storage part. The second liquid storage part is arranged around the mounting hole, and at least part of the second liquid storage part covers the two mounting holes;

[0007] Wherein, the density of the first liquid storage part is less than the density of the second liquid storage part.

[0008] In some embodiments, at least part of the second liquid storage part is located between two adjacent mounting holes.

[0009] In some embodiments, part of the second liquid storage part is located between two adjacent mounting holes.

[0010] In other embodiments, the entire second liquid storage part is located between two adjacent mounting holes.

[0011] In some embodiments, the second liquid storage part penetrates through the first liquid storage part in the first direction.

[0012] In some embodiments, the thickness of the second liquid storage part is not less than the aperture diameter of the mounting hole;

[0013] In some embodiments, the width of the second liquid storage part is not less than the spacing between two adjacent mounting holes.

[0014] In some embodiments, the thickness of the second liquid storage part is not less than the maximum thickness of the first liquid storage part;

[0015] In some embodiments, the width of the second liquid storage part is not less than the spacing between two adjacent mounting holes.

[0016] In some embodiments, the density ratio of the second liquid storage part to the first liquid storage part is (1.1 - 4):1.

[0017] In some embodiments, the thickness ratio of the first liquid storage part to the second liquid storage part is 17:1 - 1:17.

[0018] In some embodiments, the second liquid storage part is completely covered by the first liquid storage part, the connecting part between the two mounting holes forms the second liquid storage part, the thickness of the second liquid storage part is not less than the aperture diameter of the mounting hole, and the width of the second liquid storage part is equal to the distance between the two mounting holes.

[0019] In some embodiments, there are two first liquid storage parts, the two first liquid storage parts are respectively connected to the second liquid storage part, and the second liquid storage part is located in the middle of the two first liquid storage parts. The two mounting holes are located at the connection of the first liquid storage part and the second liquid storage part. The thickness of the second liquid storage part is not less than the maximum thickness of the first liquid storage part, and the width of the second liquid storage part is equal to the distance between the two mounting holes.

[0020] In some embodiments, the cross-sectional shape of the first liquid storage part and the cross-sectional shape of the second liquid storage part are similar or the same, and the cross-sectional shape of the second liquid storage part is similar or the same as the cross-sectional shape of the liquid storage cotton.

[0021] In some embodiments, the second liquid storage part is completely covered by the first liquid storage part, and the two mounting holes are located inside the second liquid storage part.

[0022] In some embodiments, there are two second liquid storage parts, one mounting hole corresponds to one second liquid storage part, and the mounting hole is located inside the second liquid storage part. The two second liquid storage parts are arranged at intervals.

[0023] In some embodiments, the density of the first liquid storage portion gradually decreases from a position close to the mounting hole to a position far from the mounting hole.

[0024] In some embodiments, the liquid storage cotton is provided with incisions which extend from the outer periphery of the liquid storage cotton inward and communicate with the mounting holes, and the number of the incisions is correspondingly set with the number of the mounting holes.

[0025] In some embodiments, the cross-section of the liquid storage cotton is one of a spindle shape, a circular shape, an oval shape, a parallelogram shape, a rectangular shape, a square shape, a triangular shape or a kidney shape.

[0026] In some embodiments, the cross-section of the second liquid storage portion is at least one of a square shape, a rectangular shape, a parallelogram shape, a rhombus shape, a pentagram shape, a triangular shape, and various irregular water droplet shapes and shuttle shapes.

[0027] The second aspect of the present application provides an electronic atomizer, including an atomization core, a battery, a circuit board, and the liquid storage cotton described in the first aspect. The battery is connected to the atomization core through the circuit board, and the atomization core is disposed in the mounting hole.

[0028] The liquid storage cotton and the electronic atomizer provided by the embodiments of the present application realize dual-channel horizontal and vertical oil supply by providing at least two mounting holes. By providing at least two mounting holes, the path of the aerosol matrix for horizontal transportation can be greatly reduced, so that the aerosol matrix in the liquid storage cotton can be quickly transported to the atomization core in the mounting hole, thereby improving the utilization rate of the aerosol matrix. Moreover, by setting the density of the first liquid storage portion to be less than that of the second liquid storage portion, since the density of the outer first liquid storage portion is small, the porosity of the first liquid storage portion is relatively large, so the capillary effect is weak, resulting in poor liquid locking ability. While the second liquid storage portion has a large density, small and numerous pores, so it has a stronger capillary effect. When the electronic atomizer is working, as the aerosol matrix inside the liquid storage cotton is continuously consumed, since the capillary effect of the connecting part (the second liquid storage portion) of the two mounting holes is stronger than that of the outer first liquid storage portion, and the liquid locking ability of the first liquid storage portion is relatively weak, the aerosol matrix of the first liquid storage portion continuously flows to the atomization core in the two mounting holes, relieving the oil supply pressure of the second liquid storage portion, preventing the occurrence of the phenomenon of the atomization core getting burnt due to insufficient oil supply, and at the same time improving the utilization rate of the aerosol matrix at the periphery (the first liquid storage portion) of the liquid storage cotton.

[0045] An embodiment of the present application provides a liquid storage cotton, as Figures 1 to 7 shown, the liquid storage cotton is provided with at least two mounting holes 100, and the mounting holes 100 are used for mounting an atomization core;

[0046] The liquid storage cotton includes a first liquid storage part 10 and a second liquid storage part 20. The first liquid storage part 10 covers at least part of the second liquid storage part 20. The second liquid storage part 20 is arranged around the mounting holes 100, and the second liquid storage part 20 covers at least part of at least two mounting holes 100;

[0047] Among them, the density of the first liquid storage part 10 is less than the density of the second liquid storage part 20.

[0048] Compared with the prior art, the liquid storage cotton has only one mounting hole 100, so the path of the aerosol matrix for lateral transportation is relatively long. In the embodiment of the present application, by providing at least two mounting holes 100, dual-channel lateral and longitudinal oil transportation is realized. By providing at least two mounting holes 100, the path of the aerosol matrix for lateral transportation can be greatly reduced, enabling the aerosol matrix in the liquid storage cotton to be quickly transported to the atomization core in the mounting hole 100, thereby improving the utilization rate of the aerosol matrix. Moreover, by setting the density of the first liquid storage part 10 to be less than that of the second liquid storage part 20, since the density of the outer first liquid storage part 10 is small, the porosity of the first liquid storage part 10 is relatively large, so the capillary effect is weak, resulting in poor liquid locking ability. While the density of the second liquid storage part 20 is large, with small and numerous pores, it has a stronger capillary effect. When the electronic atomizer is working, as the aerosol matrix inside the liquid storage cotton is continuously consumed, due to the capillary effect of the connecting part (the second liquid storage part 20) of the two mounting holes 100 being stronger than that of the outer first liquid storage part 10, and the liquid locking ability of the first liquid storage part 10 being relatively weak, the aerosol matrix of the first liquid storage part 10 continuously flows into the atomization core in the two mounting holes 100, relieving the oil supply pressure of the second liquid storage part 20, preventing the occurrence of the phenomenon of burnt cores due to insufficient oil supply, and at the same time improving the utilization rate of the aerosol matrix in the periphery (the first liquid storage part 10) of the liquid storage cotton.

[0049] It should be noted that the first liquid storage part 10 covers at least part of the second liquid storage part 20, which includes two meanings: one is that the first liquid storage part 10 completely covers the second liquid storage part 20 (as shown in Figure 1 and Figure 2 ), and the other is that the first liquid storage part 10 partially covers the second liquid storage part 20 (as shown in Figure 3 ). The second liquid storage part 20 is arranged around the mounting hole 100, and the second liquid storage part 20 covers at least part of the two mounting holes 100, which also includes two meanings: one is that the second liquid storage part 20 completely covers the mounting hole 100 (that is, both mounting holes 100 are located inside the second liquid storage part 20), and the other is that the second liquid storage part 20 partially covers the mounting hole 100 (that is, the mounting hole 100 is located at the connection between the first liquid storage part 10 and the second liquid storage part 20).

[0050] In an application, the method for preparing the liquid storage cotton can be one-step forming (the first liquid storage part 10 and the second liquid storage part 20 are integrally formed), or it can be step-by-step forming (that is, first prepare the second liquid storage part 20, and then stack the peripheral fiber layer on this basis to form the first liquid storage part 10). The fibers used for the liquid storage cotton are filaments, which can be single-component or double-component. The double-component fibers can be core-sheath structure, eccentric structure, side-by-side structure, orange segment structure, and sea-island structure. The first liquid storage part 10 and the second liquid storage part 20 of the liquid storage cotton can be of the same material or different materials, and the materials include but are not limited to one or several of PA (polyamide), PET (polyester), PP (polypropylene), PE (polyethylene), PP / PE, PET / PA, and PET / PE.

[0051] In some embodiments of the present application, the density ratio of the second liquid storage part 20 to the first liquid storage part 10 is (1.1 to 4):1. In a specific embodiment, the density ratio of the second liquid storage part 20 to the first liquid storage part 10 can be any ratio within the range of (1.1 to 4):1, such as 1.1:1, 1.5:1, 1.8:1, 2:1, 2.5:1, 3:1, 3.5:1, 4:1, etc. Within this density ratio range, it can be ensured that the liquid locking ability of the first liquid storage part 10 located on the periphery is weaker than that of the second liquid storage part 20 located inside, and the second liquid storage part 20 is located between two mounting holes 100 (atomizing core), and the oil supply ability requirement for the second liquid storage part 20 is higher. Therefore, on this basis, the aerosol matrix in the first liquid storage part 10 will continuously transport towards the second liquid storage part 20, thereby avoiding wicking due to insufficient oil supply and further improving the utilization rate of the aerosol matrix in the first liquid storage part 10.

[0052] In some embodiments of the present application, the thickness ratio of the first liquid storage part 10 to the second liquid storage part 20 is 17:1 to 1:17. In a specific embodiment, the thickness ratio of the first liquid storage part 10 to the second liquid storage part 20 can be any ratio within the range of 17:1 to 1:17, such as 17:1, 16:2, 15:3, 10:7, 7:10, 1:1, etc. Within the above ratio range, the liquid storage ability and liquid locking ability of the first liquid storage part 10 and the second liquid storage part 20 can be ensured, and the aerosol matrix in the first liquid storage part 10 can continuously transport towards the second liquid storage part 20 to improve the utilization rate of the aerosol matrix in the first liquid storage part.

[0053] In some embodiments of the present application, as Figures 1 to 7 shown, at least part of the second liquid storage part 20 is located between two adjacent mounting holes 100. In some preferred embodiments, as Figure 4 and Figure 5 shown, part of the second liquid storage part 20 is located between two adjacent mounting holes 100. In some other preferred embodiments, as Figures 1 to 3, the entire second liquid storage part 20 is located between two adjacent mounting holes 100. In some embodiments, the thickness of the second liquid storage part 20 is not less than the aperture diameter of the mounting hole 100. In some embodiments, the width of the second liquid storage part 20 is not less than the spacing between two adjacent mounting holes 100. Such a setting is to improve the liquid storage capacity and liquid supply capacity of the second liquid storage part 20. Since the second liquid storage part 20 is located between two mounting holes 100, the aerosol matrix inside it will be consumed relatively quickly. Therefore, it is necessary to improve the liquid storage capacity of the second liquid storage part 20 and the ability to transport the aerosol matrix to the atomization core in the mounting hole 100.

[0054] In some embodiments of the present application, as Figure 1 and Figure 2 shown, the second liquid storage part 20 is completely covered by the first liquid storage part 10. The connecting part between two mounting holes 100 forms the second liquid storage part 20. The thickness of the second liquid storage part 20 is not less than the aperture diameter of the mounting hole 100, and the width of the second liquid storage part 20 is equal to the distance between two mounting holes 100. That is, the second liquid storage part 20 is located inside and the first liquid storage part 10 is located on the periphery.

[0055] It should be noted that the thickness of the second liquid storage part 20 refers to the distance of the second liquid storage part 20 in the Y direction (i.e., the first direction) in the figure, and the width of the second liquid storage part 20 refers to the distance of the second liquid storage part 20 in the X direction in the figure. Similarly, the thickness of the first liquid storage part 10 refers to the distance in the first direction, and the width of the first liquid storage part 10 refers to the distance in the X direction. The above is only for facilitating the understanding of the solution and should not be construed as a limitation on the embodiments of the present application. The mounting hole 100 is usually set as a circular shape, so its aperture diameter is the diameter. In other embodiments, it can also be a square hole, a long strip hole, and other irregular holes. Then, the aperture diameter of the mounting hole 100 is the vertical distance of the mounting hole 100 in the Y direction.

[0056] In some embodiments of the present application, as Figure 3 and Figure 7 shown, the second liquid storage part 20 penetrates through the first liquid storage part 10 in the first direction. Such a setting can maximize the liquid storage capacity of the second liquid storage part, thereby ensuring the liquid supply to the atomization core in the mounting hole 100. In some embodiments, as Figure 3 shown, the thickness of the second liquid storage part 20 is not less than the maximum thickness of the first liquid storage part 10. In some embodiments, the width of the second liquid storage part 20 is not less than the spacing between two adjacent mounting holes 100. In some embodiments of the present application, as Figure 3As shown, there are two first liquid storage parts 10. The two first liquid storage parts 10 are respectively connected to the second liquid storage part 20, and the second liquid storage part 20 is located in the middle of the two first liquid storage parts 10. The two mounting holes 100 are located at the connection of the first liquid storage part 10 and the second liquid storage part 20. The thickness of the second liquid storage part 20 is not less than the maximum thickness of the first liquid storage part 10, and the width of the second liquid storage part 20 is equal to the distance between the two mounting holes 100. In this embodiment, the volume of the second liquid storage part 20 is relatively large, which can store more aerosol matrix and can ensure the oil supply demand for the atomization core in the mounting hole 100.

[0057] In some embodiments of the present application, as Figure 4 shown, the cross-sectional shape of the first liquid storage part 10 is similar to or the same as the cross-sectional shape of the second liquid storage part 20, and the cross-sectional shape of the second liquid storage part 20 is similar to or the same as the cross-sectional shape of the liquid storage cotton. In the embodiments of the present application, the overall shape of the liquid storage cotton is oval for illustration. Both the first liquid storage part 10 and the second liquid storage part 20 are designed in an oval shape. On the one hand, it is convenient for production, and on the other hand, it is more suitable for the current electronic atomizer. Further, as Figure 4 shown, the second liquid storage part 20 is completely covered by the first liquid storage part 10, and the two mounting holes 100 are located in the second liquid storage part 20. Such a setting further ensures the oil supply from the second liquid storage part 20 to the atomization core in the mounting hole 100, effectively avoiding the occurrence of the situation of the atomization core getting clogged.

[0058] In some embodiments of the present application, as Figure 5 shown, there are two second liquid storage parts 20. One mounting hole 100 is provided corresponding to one second liquid storage part 20, and the mounting hole 100 is located in the second liquid storage part 20, and the two second liquid storage parts 20 are arranged at intervals. In this way, the oil supply can be carried out for the atomization core in each mounting hole 100, improving the efficiency. In some embodiments, the two liquid storage parts can also be connected.

[0059] In some embodiments of the present application, from the position close to the mounting hole 100 to the position far from the mounting hole 100, the density of the first liquid storage part 10 gradually decreases. Thus, the liquid locking ability is worse at the position farther from the mounting hole 100. Therefore, the aerosol matrix will be transported towards the position close to the mounting hole 100 (i.e., the position where the atomization core is located) under the action of capillary effect, thereby improving the utilization rate of the aerosol matrix of the first liquid storage part 10.

[0060] In some embodiments of the present application, as Figures 2 to 7As shown, the liquid storage cotton is provided with an incision 200, which extends inward from the outer circumference of the liquid storage cotton and is connected to the mounting hole 100. The number of incisions 200 is set corresponding to the number of mounting holes 100. The existence of the incision 200 is to facilitate the installation of the atomizer core. The incision 200 is to cut the first liquid storage part 10 and / or the second liquid storage part 20 and communicate with the mounting hole 100, so that when installing the atomizer core, the incision 200 can be opened to facilitate the installation of the atomizer core. In some embodiments, the incisions 200 are symmetrically arranged, so that the aesthetics of the liquid storage cotton can be ensured.

[0061] In some embodiments of the present application, the cross-section of the liquid storage cotton is one of spindle-shaped, circular, elliptical, parallelogram, rectangular, square, triangular or waist-shaped. Figures 1 to 7 As shown, examples of elliptical and circular shapes are provided. In other embodiments, the shapes may be spindle-shaped, square, rectangular, etc.

[0062] In some embodiments of the present application, the cross-section of the second liquid storage portion 20 is at least one of a square, a rectangle, a parallelogram, a rhombus, a pentagon, a triangle, and various irregular teardrop shapes and shuttle shapes.

[0063] An embodiment of the present application also provides an electronic atomizer, including an atomizer core (shown in the figure), a battery (shown in the figure), a circuit board (shown in the figure) and the liquid storage cotton described in the first aspect, the battery is connected to the atomizer core through the circuit board, and the atomizer core is arranged in the mounting hole.

[0064] The electronic atomizer provided in the embodiment of the present application includes the liquid storage cotton described in the first aspect, including the above-mentioned beneficial effects. At the same time, the electronic atomizer of the present application can provide the user with a better suction taste and can also increase the service life of the electronic atomizer.

[0065] In the above embodiments, the description of each embodiment has its own emphasis. For parts that are not described or recorded in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0066] The embodiments described above are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, a person skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents.
