In the related art, the atomization matrix is ​​stored in a liquid storage component, and the atomization matrix is ​​transmitted to the atomization core through the connectivity of the liquid storage component's own gaps. However, when the atomization matrix in the liquid storage component is consumed to a certain extent, the residual atomization matrix cannot be effectively adsorbed and transferred to the atomization core due to the poor pore connectivity of the liquid storage component, which easily produces a burnt smell and a high residual oil rate. Summary of the invention

[0004] The present application provides a method for preparing a liquid storage component, which is applied to an atomization component to store an atomization matrix. The method for preparing the liquid storage component comprises the following steps: cutting a fiber block to form a fiber sheet, wherein the thickness direction of the fiber sheet is the same as the fiber direction of the fiber sheet, wherein the fiber sheet comprises a first bonding surface and a second bonding surface having a preset angle with the thickness direction; and curling the fiber sheet so that the first bonding surface is bonded to the second bonding surface to form the liquid storage component.

[0005] In some embodiments, the step of cutting the fiber block to form the fiber sheet includes: cutting along a fiber direction perpendicular to the fiber block to form the fiber sheet, wherein a thickness direction of the fiber sheet is perpendicular to the cutting direction.

[0006] In some embodiments, two opposite side surfaces in the length direction of the fiber sheet are cut obliquely from the first surface in the thickness direction of the fiber sheet toward the second surface to form the first and second bonding surfaces, and the area of ​​the first surface is kept smaller than that of the second surface.

[0007] In some embodiments, the step of curling the fiber sheet to combine the first bonding surface with the second bonding surface to form the liquid storage element includes: the first bonding surface and the second bonding surface are attached to each other or spaced apart.

[0008] In some embodiments, the first bonding surface and the second bonding surface have the same or matching shapes.

[0009] In some embodiments, the first bonding surface and the second bonding surface are both plane in shape.

[0010] In some embodiments, the preset angle is less than 30°.

[0011] The present application also provides a liquid storage component prepared based on the liquid storage component preparation method, wherein the liquid storage component includes fiber cotton, the fiber cotton has an axially penetrating liquid storage through hole, and the fiber direction of the fiber cotton is the same as the radial direction of the liquid storage through hole.

[0012] The present application also provides an atomization assembly, comprising the liquid storage component and an atomization core, wherein the atomization core is accommodated in the liquid storage through hole.

[0013] The present application also provides an atomization device, comprising the atomization assembly and a power supply assembly, wherein the power supply assembly is electrically connected to the atomization assembly.

[0014] According to the preparation method of the liquid storage component, the liquid storage component, the atomization assembly and the atomization device of the above-mentioned embodiment, a first bonding surface and a second bonding surface are formed by cutting two opposite side surfaces in the length direction of the fiber sheet, so that after curling the fiber sheet and combining the first bonding surface with the second bonding surface, a liquid storage component that is tight inside and loose outside is formed. Since the thickness direction of the fiber sheet is its fiber direction, the radial direction of the liquid storage component is the same as the fiber direction of the fiber sheet, which is beneficial for the atomization matrix to conduct liquid to the atomization core, avoid accumulation of the atomization matrix, thereby improving the liquid conduction efficiency and reducing the residual oil rate.

DETAILED DESCRIPTION

[0033] The present application is further described in detail below by specific embodiments in conjunction with the accompanying drawings. Wherein similar elements in different embodiments adopt associated similar element numbers. In the following embodiments, many detailed descriptions are intended to enable the present application to be better understood. However, those skilled in the art can easily recognize that some of the features can be omitted in different situations, or can be replaced by other elements, materials, and methods. In some cases, some operations related to the present application are not shown or described in the specification, in order to avoid the core part of the present application being overwhelmed by too much description, and for those skilled in the art, it is not necessary to describe these related operations in detail, and they can fully understand the related operations based on the description in the specification and the general technical knowledge in the art.

[0034] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate manner to form various implementations, and the operation steps involved in each embodiment can also be replaced or adjusted in a sequence in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for the purpose of clearly describing a certain embodiment and do not mean that the composition and / or sequence are necessary.

[0035] The serial numbers of the components in this document, such as "first", "second", etc., are only used to distinguish the objects described and do not have any order or technical meaning. The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0036] In the related art, in order to change the liquid-conducting effect of the liquid-reservoir cotton, the liquid-conducting effect of the liquid-reservoir cotton is usually adjusted by changing the material of the liquid-reservoir cotton or adjusting the fit between the liquid-reservoir cotton and the liquid-conducting cotton in the atomizer core. However, when the material of the liquid-reservoir cotton is changed and a material with stronger liquid absorption and higher porosity is adopted, the production cost of the product will increase, and the problem of atomized liquid accumulation at the end of the liquid-reservoir cotton cannot be completely solved; while in the method of adjusting the fit between the liquid-reservoir cotton and the liquid-conducting cotton in the atomizer core, the liquid-conducting efficiency can be improved in the short term, but after long-term use, the problem of atomized liquid transmission efficiency still exists, and such adjustment usually requires complex design and process, which increases the difficulty of product production.

[0037] The above two methods still cannot solve the fundamental problem that the atomized liquid at the end of the liquid storage cotton cannot be effectively utilized, especially after a long period of work, the atomized liquid is still easy to accumulate at the far end of the liquid storage cotton. The reason is that the fiber direction of the liquid storage cotton itself is the same as its axial direction, resulting in poor radial liquid conduction ability. The liquid supply to the atomizer core is relatively sufficient in the early stage, but in the later stage it is easy to cause insufficient liquid supply to the atomizer core, resulting in a high residual oil rate, and the heating element in the atomizer core is prone to dry burning or even core sticking and carbon deposition.

[0038] In response to the above problems, the present application provides a method for preparing a liquid storage component, a liquid storage component, an atomization assembly and an atomization device, so as to adjust the fiber direction of the liquid storage component to be the same as the radial direction of the liquid storage component, improve the liquid conduction efficiency of the atomized liquid, avoid the accumulation of the atomized liquid at the far end of the liquid storage component, thereby reducing the residual liquid rate of the atomized liquid, and avoid the problem of dry burning of the heating element in the atomization core or even core sticking and carbon deposition.

[0039] Embodiment 1

[0040] This embodiment provides a method for preparing a liquid storage member, wherein the liquid storage member is applied to an atomization component to store an atomization matrix, which is usually in liquid form and can generate an aerosol under the action of heating an atomization core in the atomization component.

[0041] In some embodiments, the atomization matrix may be, for example, tobacco oil, or may be a component such as a fragrance, which is heated and atomized by the atomization core in the atomization assembly.

[0042] See also Figure 1-Figure 5 As shown, the preparation method of the liquid storage element provided in this embodiment includes the following steps:

[0043] Step S100: cutting the fiber block 100 to form a fiber sheet 101, wherein the thickness direction of the fiber sheet 101 is the same as the fiber direction of the fiber sheet 101, wherein the fiber sheet 101 comprises a first bonding surface 1011 and a second bonding surface 1012 having a preset angle with the thickness direction.

[0044] In this embodiment, the fiber block 100 is made of fiber cotton and has a single fiber direction. The fiber sheet 101 formed after cutting also has a fiber direction, wherein the fiber direction of the fiber block 100 is the pore direction of the fiber block 100, and the fiber direction of the fiber sheet 101 is the pore direction of the fiber sheet 101. For easy distinction, the fiber direction of the fiber block 100 is defined as a first fiber direction F1, and the fiber direction of the fiber sheet 101 is defined as a second fiber direction F2, as shown in FIG. Figure 2 As shown, the fiber block 100 has a single first fiber direction F1, wherein the first fiber direction F1 is Figure 2 The direction indicated by the dash-dot arrow. Figure 3 and Figure 4 As shown, the thickness direction of the fiber sheet 101 is the same as the second fiber direction F2 of the fiber sheet 101. In other words, the thickness direction of the fiber sheet 101 is the second fiber direction F2 thereof.

[0045] Among them, the fiber block, fiber sheet, and fiber cotton can be Polyamide, referred to as PA, also known as polyamide fiber, commonly known as nylon or nylon; or, the fiber cotton can also be Polyethy l ene terephtha l ate, referred to as PET, also known as thermoplastic polyester / saturated polyester, commonly known as polyester resin, which is a condensation product of terephthalic acid and ethylene glycol.

[0046] Particularly, during the process of cutting the fiber block 100 , the second fiber direction F1 of the fiber sheet 101 is the same as the first fiber direction F1 of the fiber block 100 , and the two are only different in thickness, and the fiber sheet 101 is formed by cutting the fiber block 100 .

[0047] The fiber sheet 101 formed by cutting the fiber block 100 has a first surface 1013 and a second surface 1014 respectively formed in the thickness direction thereof. In the subsequent preparation steps, the first surface 1013 can be enclosed to form the liquid storage through hole 21 of the fiber cotton 20, and the second surface 1014 is formed as the outer wall of the fiber cotton 10. The fiber cotton 10 is the liquid storage part 200.

[0048] In step S100, Figure 3 and Figure 4 As shown, the two surfaces of the fiber sheet 101 in the thickness direction are the first surface 1013 and the second surface 1014, respectively, and the first bonding surface 1011 and the second bonding surface 1012 are formed by obliquely cutting the two opposite side surfaces in the length direction of the fiber sheet 101 from the first surface 1013 in the thickness direction of the fiber sheet 101 to the second surface 1014, and after cutting, the area of ​​the first surface 1013 can be kept smaller than the area of ​​the second surface 1014.

[0049] In this step, combine Figure 3 and Figure 4 As shown, the two opposite side surfaces of the fiber sheet 101 in the length direction are cut obliquely from the first surface 1013 in the thickness direction of the fiber sheet 101 to the second surface 1014, so that the two opposite side surfaces in the length direction of the fiber sheet 101 are formed into an oblique first bonding surface 1011 and a second bonding surface 1012. Since the first bonding surface 1011 and the second bonding surface 1012 are formed by oblique cutting from the first surface 1013 to the second surface 1014, the area of ​​the first surface 1013 is smaller than the area of ​​the second surface 1014.

[0050] Step S200 : curling the fiber sheet 101 to combine the first bonding surface 1011 with the second bonding surface 1012 to form the liquid storage element 200 .

[0051] In step S200 , the first surface 1013 encloses the liquid storage through hole 21 of the liquid storage member 200 , and the second surface 1014 forms the outer surface of the liquid storage member 200 .

[0052] See also Figure 4 As shown, the first bonding surface 1011 and the second bonding surface 1012 are combined by curling the fiber sheet 101, thereby forming a liquid storage member 200, and the liquid storage member 200 is a liquid storage structure used in the atomization component, which can store the atomization matrix in liquid form by adsorption. Among them, the liquid storage through hole 21 is a through hole structure formed inside the axial direction of the liquid storage member 200, which can be used to accommodate the atomization core structure of the atomization component to conduct the atomization matrix to the atomization core, and the atomization core heats the atomization matrix to generate aerosol.

[0053] It should be noted that, in order to make the first surface 1013 enclose the liquid storage hole 21 of the liquid storage member 200 after the first bonding surface 1011 and the second bonding surface 1012 are bonded during the curling of the fiber sheet 101, Figure 5 Taking the perspective shown as an example, assuming that the first surface 1013 is the inner surface of the fiber sheet 101, and the second surface 1014 is the outer surface of the fiber sheet 101, the fiber sheet 101 needs to be curled toward its inner surface, and the first bonding surface 1011 is combined with the second bonding surface 1012, so that the liquid storage member 200 can be curled. During the curling process, the first surface 1013 is enclosed to form a liquid storage through hole 21 that penetrates the liquid storage member 200 in the axial direction, and the second surface 1014 is formed as the outer surface of the liquid storage member 200.

[0054] Since the thickness direction of the fiber sheet 101 is the second fiber direction F2, the radial direction of the formed liquid storage component 200 is the second fiber direction F2 of the fiber sheet 101. It can be seen that the second fiber direction F2 is the same as the pore direction of the fiber sheet 101, and the atomizing matrix in liquid form is conducted along the pore direction, thus forming a liquid storage component 200 with the second fiber direction F2 as a radial direction. After the atomizing core is accommodated in the liquid storage channel 21, it is beneficial for the atomizing matrix to conduct liquid to the atomizing core, avoiding accumulation of the atomizing matrix, thereby improving the liquid conduction efficiency.

[0055] At the same time, in the process of curling the fiber sheet 101, since the area of ​​the first surface 1013 is smaller than the area of ​​the second surface 1014, the first surface 1013 is compressed and the second surface 1014 is stretched during the curling process. In this way, the liquid storage hole 21 enclosed by the first surface 1013 and the outer wall of the liquid storage component 200 formed by the second surface 1014 make the liquid storage component 200 present a tight inside and loose outside state. After the atomizer core is accommodated in the liquid storage hole 21, the hole wall of the liquid storage hole 21 can be more closely fitted to the atomizer core, thereby improving the fit between the liquid storage component 200 and the atomizer core, so as to further improve the liquid conduction efficiency.

[0056] As described above, the first bonding surface 1011 and the second bonding surface 1012 are formed by cutting the two opposite sides in the length direction of the fiber sheet 101, so that the area of ​​the first surface 1013 in the thickness direction of the fiber sheet 101 is smaller than the area of ​​the second surface 1014, so that after curling the fiber sheet 101 and combining the first bonding surface 1011 with the second bonding surface 1012, a liquid storage member 200 that is tight inside and loose outside is formed. Since the thickness direction of the fiber sheet 101 is the second fiber direction F2, the radial direction of the liquid storage member 200 is the same as the second fiber direction F2 of the fiber sheet 101, which is conducive to the atomization matrix to guide the liquid to the atomization core, avoid the accumulation of the atomization matrix, thereby improving the liquid guiding efficiency and reducing the residual oil rate. Further, the problem of dry burning of the atomization core can be avoided.

[0057] like Figure 2 As shown, in step S100 , the step of cutting the fiber block 100 to form the fiber sheet 100 includes: cutting along a first fiber direction F1 perpendicular to the fiber block 100 to form the fiber sheet 101 .

[0058] by Figure 2 As shown in the figure, the first fiber direction F1 of the fiber block 100 is the Y-axis direction, and the fiber block 100 is cut along the Z-axis direction perpendicular to the Y-axis direction, and the thickness direction of the formed fiber sheet 101 is the same as the second fiber direction F2 of the fiber sheet 101. Figure 2 As shown, the cutting portion is parallel to the X-axis direction, and a suitable width is selected to meet the required thickness of the fiber sheet 101. Figure 2 The dotted line parallel to the X-axis direction in FIG. 1 represents a cutting position where the fiber block 100 is cut.

[0059] In this embodiment, the thickness direction of the fiber sheet 101 formed by cutting along the first fiber direction F1 perpendicular to the fiber block 100 is perpendicular to the cutting direction.

[0060] In step S200, the fiber sheet 101 is curled so that the first bonding surface 1011 and the second bonding surface 1012 are bonded to form a liquid storage component 200, and the first surface 1013 encloses the liquid storage hole 21 of the liquid storage component 200. The steps include: the first bonding surface 1011 and the second bonding surface 1012 are fitted together or spaced apart. When fitted together, the first bonding surface 1011 and the second bonding surface 1012 can be bonded together by gluing, and when spaced apart, there is a gap between the first bonding surface 1011 and the second bonding surface 1012.

[0061] In a specific embodiment, when the liquid storage device 200 is installed in a liquid storage cup for installing the liquid storage device, the fiber sheet 101 is kept in a curled state by the inner cavity of the liquid storage cup, so as to form the liquid storage through hole 21. The first bonding surface 1011 and the second bonding surface 1012 are not bonded by gluing, and under the action of the inner cavity of the liquid storage cup, a gap is generated between the first bonding surface 1011 and the second bonding surface 1012 to form a spaced state.

[0062] In the present application, the shapes of the first bonding surface 1011 and the second bonding surface 1012 are the same or match each other. For example, the shapes of the first bonding surface 1011 and the second bonding surface 1012 are the same. In this case, the first bonding surface 1011 and the second bonding surface 1012 are the same and inclined planes for fitting. In the case where the shapes of the first bonding surface 1011 and the second bonding surface 1012 match each other, the first bonding surface 1011 may be a concave surface, and the second bonding surface 1012 may be a convex surface that matches or fits with the concave surface.

[0063] Of course, to facilitate the processing and preparation of the product, the first bonding surface 1011 and the second bonding surface 1012 in the present embodiment are both planes, that is, identical and inclined planes, so that they can fit together or be spaced apart after curling, and the area of ​​the first surface 1013 can be made smaller than the area of ​​the second surface 1014, so as to form a liquid storage part 200 that is tight inside and loose outside after curling.

[0064] In this embodiment, the first bonding surface 1013 and the second bonding surface 1014 of the fiber sheet 101 are identical and inclined planes, and a preset angle between the first bonding surface 1013 and the second bonding surface 1014 and the thickness direction of the fiber sheet 101 is less than 30°.

[0065] In this embodiment, the fiber block 100 is made of thermoplastic polyester or a mixture of thermoplastic polyester and polyamide. Of course, the fiber block 100 can also be made of other fiber cottons alone or in combination, which can be selected according to actual needs and will not be repeated here.

[0066] Embodiment 2

[0067] This embodiment provides a liquid storage element 200 prepared based on the liquid storage element preparation method in Embodiment 1, see Figure 5 As shown, the liquid storage element 200 includes fiber cotton 20 , and the fiber cotton 20 has a liquid storage through hole 21 axially penetrating therethrough, and the fiber direction of the fiber cotton 20 is the same as the radial direction of the liquid storage through hole 21 .

[0068] The fiber cotton 20 is formed by curling a fiber sheet 101 whose fiber direction is the same as the thickness direction, and the fiber direction of the fiber sheet 101 is the second fiber direction F2.

[0069] In a specific embodiment, Figure 2-Figure 5 As shown, the fiber block 100 is cut to form a fiber sheet 101, the thickness direction of the fiber sheet 101 is the same as the second fiber direction F2 of the fiber sheet 101, the two surfaces of the fiber sheet 101 in the thickness direction are respectively the first surface 1013 and the second surface 1014, the fiber sheet 101 is respectively formed with the first surface 1013 and the second surface 1014 in the thickness direction, and the first bonding surface 1011 and the second bonding surface 1012 are formed by cutting the two opposite side surfaces in the length direction of the fiber sheet 101 in an inclined manner from the first surface 1013 in the thickness direction of the fiber sheet 101 to the second surface 1014, and after cutting, the area of ​​the first surface 1013 can be kept smaller than the area of ​​the second surface 1014. Among them, the first bonding surface 1011 and the second bonding surface 1012 of the fiber sheet 101 have a preset angle with the thickness direction of the fiber sheet 101.

[0070] The fiber sheet 101 is curled to combine the first bonding surface 1011 with the second bonding surface 1012 to form the liquid storage element 200 . The first surface 1013 of the fiber sheet 101 encloses the liquid storage hole 21 of the liquid storage element 200 , and the second surface 1014 forms the outer surface of the liquid storage element 200 .

[0071] From the above, it can be seen that the fiber cotton 20 is formed by curling the fiber sheet 101, and since the thickness direction of the fiber sheet 101 is its second fiber direction F2, the radial direction of the formed liquid storage component 200 is the second fiber direction F2 of the fiber sheet 101. It can be seen that the second fiber direction F2 of the fiber sheet 101 is the same as the pore direction of the fiber sheet 101, and the atomizing matrix in liquid form is conducted along the pore direction, thus forming a liquid storage component 200 with a radial fiber direction. After the atomizing core is inserted into the liquid storage channel 21, it is beneficial for the atomizing matrix to conduct liquid to the atomizing core, avoiding accumulation of the atomizing matrix, so as to improve the liquid conduction efficiency.

[0072] At the same time, in the process of curling the fiber sheet 101, since the area of ​​the first surface 1013 is smaller than the area of ​​the second surface 1014, the first surface 1013 is compressed and the second surface 1014 is stretched during the curling process. In this way, the liquid storage hole 21 enclosed by the first surface 1013 and the outer wall of the liquid storage component 200 formed by the second surface 1014 make the liquid storage component 200 present a tight inside and loose outside state. After the atomizer core is inserted into the liquid storage hole 21, the hole wall of the liquid storage hole 21 can be more closely fitted to the atomizer core, thereby improving the fit between the liquid storage component 200 and the atomizer core, so as to further improve the liquid conduction efficiency.

[0073] In the process of curling the fiber sheet 101 to form the liquid storage component 200, the first bonding surface 1011 and the second bonding surface 1012 are attached to each other or spaced apart. When attached to each other, the first bonding surface 1011 and the second bonding surface 1012 can be bonded together by gluing, and when spaced apart, there is a gap between the first bonding surface 1011 and the second bonding surface 1012.

[0074] In a specific embodiment, when the liquid storage device 200 is installed in a liquid storage cup for installing the liquid storage device, the fiber sheet 101 is kept in a curled state by the inner cavity of the liquid storage cup, so as to form the liquid storage through hole 21. The first bonding surface 1011 and the second bonding surface 1012 are not bonded by gluing, and under the action of the inner cavity of the liquid storage cup, a gap is generated between the first bonding surface 1011 and the second bonding surface 1012 to form a spaced state.

[0075] The shapes of the first bonding surface 1011 and the second bonding surface 1012 are the same or match each other. For example, the shapes of the first bonding surface 1011 and the second bonding surface 1012 are the same. In this case, the first bonding surface 1011 and the second bonding surface 1012 are the same and inclined planes for fitting. In the case where the shapes of the first bonding surface 1011 and the second bonding surface 1012 match each other, the first bonding surface 1011 may be a concave surface, and the second bonding surface 1012 may be a convex surface that matches or fits with the concave surface.

[0076] Of course, to facilitate the processing and preparation of the product, the first bonding surface 1011 and the second bonding surface 1012 in the present embodiment are both planes, that is, identical and inclined planes, so that they can fit together or be spaced apart after curling, and the area of ​​the first surface 1013 can be made smaller than the area of ​​the second surface 1014, so as to form a liquid storage part 200 that is tight inside and loose outside after curling.

[0077] In this embodiment, the first bonding surface 1013 and the second bonding surface 1014 of the fiber sheet 101 are identical and inclined planes, and a preset angle between the first bonding surface 1013 and the second bonding surface 1014 and the thickness direction of the fiber sheet 101 is less than 30°.

[0078] In the liquid storage member 200 provided in this embodiment, the first bonding surface 1011 and the second bonding surface 1012 are formed by cutting the two opposite sides in the length direction of the fiber sheet 101, so that the area of ​​the first surface 1013 in the thickness direction of the fiber sheet 101 is smaller than the area of ​​the second surface 1014, so that after the fiber sheet 101 is curled and the first bonding surface 1011 is combined with the second bonding surface 1012, a liquid storage member 20 that is tight inside and loose outside is formed. Since the thickness direction of the fiber sheet 101 is the second fiber direction F2, the radial direction of the liquid storage member 20 is the same as the second fiber direction F2 of the fiber sheet 101, which is conducive to the liquid conduction of the atomization matrix to the atomization core, avoiding the accumulation of the atomization matrix, thereby improving the liquid conduction efficiency and reducing the residual oil rate.

The atomizer core 30 is accommodated in the liquid storage through hole 21 .

[0081] The atomizer assembly 300 provided in this embodiment also includes a cup body 301, a top cover 302 and a bottom cover 303, wherein the inner cavity of the cup body 301 is a hollow structure with openings at both ends, and the top cover 302 and the bottom cover 303 are respectively installed at the openings at both ends of the cup body 301 to enclose an installation cavity with the cup body 301, and the liquid storage component 200 is installed in the installation cavity.

[0082] The atomizer core 30 includes an atomizer tube 31, a liquid guide member 32 and a heater 33, wherein the liquid guide member 32 is inserted into the interior of the atomizer tube 31, and the liquid guide member 32 is a hollow columnar structure. The heater 33 is installed in the inner cavity of the liquid guide member 33. The heater 33 is preferably a mesh heating wire and is distributed in the inner cavity of the liquid guide member 32 to form circumferential heating on the liquid guide member 33.

[0083] The atomizing tube 31 is provided with a notch 311, and the liquid guiding member 32 has a protrusion 321. After the liquid guiding member 32 is inserted into the atomizing tube 31, the protrusion 321 can extend to the outside of the atomizing tube 31 through the notch 311. After the atomizing core 30 is inserted into the liquid storage through hole 21, the protrusion 321 of the liquid guiding member 32 can fully contact with the liquid storage member 200, so as to improve the liquid guiding efficiency.

[0084] The atomized substrate conducted to the liquid guide member 32 can be heated and atomized to generate aerosol under the action of the heating member 32 .

[0085] In one embodiment of the present application, a protrusion 3031 is provided on the bottom cover 303 , and the atomizer tube 31 is plugged into the protrusion 3031 to be fixed on the bottom cover 303 .

[0086] A first air hole 3021 is provided on the top cover 302, and a second air hole 3032 is also provided on the bottom cover 303. The first air hole 3021 is communicated with the liquid storage through hole 21, and the second air hole 3032 is communicated with the atomization tube 31. In this way, external air can enter the interior of the atomization tube 31 through the second air hole 3032. In the process of heating the atomization matrix, the heating element 33 heats the atomization matrix to generate particles. Under the action of external air, the particles can be mixed with the atomization matrix to form an aerosol, and the aerosol is output through the first air hole 3021.

[0087] See also Fig. 9 and Fig.10 As shown, in order to facilitate external air to enter the interior of the atomizing tube 31 through the second air hole 3032, a suction nozzle 40 may be further provided above the top cover 302, wherein the suction nozzle 40 may be fixedly connected or detachably connected to one end of the cup body where the top cover 302 is provided. The suction nozzle 40 has a suction nozzle channel 41, which is communicated with the first air hole 3021. The user may inhale through the suction nozzle 40, so that external air can enter the interior of the atomizing tube 31 through the second air hole 3032. Of course, the generated aerosol is output through the suction nozzle channel 41.

[0088] Since condensation is easily generated due to cooling during the output of the aerosol through the nozzle channel 41, in order to prevent the condensation from flowing back, in this embodiment, a liquid absorbing member 42 is further provided between the nozzle 40 and one end of the cup body 301 where the top cover 302 is provided, and the liquid absorbing member 42 can absorb the generated condensation.

[0089] It should be noted that, in actual application, a blocking piece for blocking the nozzle channel 41 is also provided on the nozzle 40 to prevent the atomized matrix from leaking through the nozzle channel 41 .

[0091] This embodiment also provides an atomizing device, see Figure 11-13 As shown, the atomizing device includes the atomizing assembly 300 in the third embodiment, and the atomizing device also includes a power supply assembly 50, and the power supply assembly 50 is detachably or fixedly connected to the atomizing assembly 300.

[0092] In a specific embodiment, the atomizing device further comprises a power supply shell 51, one end of which has an opening, and a power supply cover 52 is arranged at the opening at one end of the power supply shell 51, and the power supply cover 52 is detachably connected to the opening, and the power supply assembly 50 is arranged inside the power supply shell 51, and the installation of the power supply assembly 50 is facilitated by the arrangement of the power supply cover 52. The other end of the power supply shell 51 is detachably or fixedly connected to one end of the cup body 301 of the atomizing assembly 300 where the bottom cover 303 is arranged.

[0093] The power supply component 50 can provide the heating element 33 with the energy required for heating. The power supply component 50 is preferably a rechargeable lithium battery to extend the service life of the atomization device.

[0094] The atomization device provided in this embodiment further includes a shell 60 , wherein the power supply shell 51 and the cup body 301 are both arranged inside the shell 60 .

[0095] In this embodiment, an air inlet hole 521 is further provided on the power supply shell 51, and there is a certain gap between the power supply component 50 and the inner wall of the power supply shell 51, so that the air inlet hole 521 and the second air hole 3032 can be kept in a connected state. When the user sucks through the nozzle 40, external air can enter through the air inlet hole 521 and the second air hole 3032.

[0096] In this embodiment, the atomization device of the liquid storage member 200 with the fiber direction in the radial direction is compared with the atomization device of the liquid storage member with the fiber direction in the axial direction, see Table 1.

[0097] In Table 1, Samples 1 to 3 are liquid storage parts with the fiber direction in the axial direction, and Samples 4 to 6 are liquid storage parts with the fiber direction in the radial direction. The TPM (Total Particulate Matter) in Table 1 is the total amount of particulate matter in the aerosol generated by the atomizer during each puff, usually calculated based on the mass change per 100 puffs, that is, oil consumption = instrument before puffing - instrument after puffing, residual oil ratio = remaining oil / (remaining oil + oil consumption), wherein the mass of the instrument after puffing is the mass after cleaning, and the mass of the instrument before puffing is the mass before puffing.

[0098] Combination Fig.14 As shown, it can be seen that, overall, the liquid storage member with the fiber direction in the radial direction has a huge advantage in reducing the residual oil rate compared with the liquid storage member with the fiber direction in the axial direction. Secondly, although the average TPM is not much different between the two, it can be seen from Table 1 that the liquid storage member with the fiber direction in the radial direction can significantly increase the number of suction ports, thereby extending the service life of the atomization device.

[0100] Table 1

[0101] In summary, in the preparation method of the liquid storage member, the liquid storage member, the atomization assembly and the atomization device provided by the present application, the first bonding surface and the second bonding surface are formed by cutting the two opposite sides in the length direction of the fiber sheet, so that after the fiber sheet is curled and the first bonding surface is combined with the second bonding surface, a liquid storage member that is tight inside and loose outside is formed. Since the thickness direction of the fiber sheet is its fiber direction, the radial direction of the liquid storage member is the same as the fiber direction of the fiber sheet, which is conducive to the atomization matrix to guide the liquid to the atomization core, avoid the accumulation of the atomization matrix, thereby improving the liquid guiding efficiency and reducing the residual oil rate. Furthermore, the problem of dry burning of the atomization core can be avoided.
