DETAILED DESCRIPTION

[0039] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0040] Existing liquid storage components are generally made of PET (polyethylene terephthalate) and PA (polyamide) fiber materials. Due to the longitudinal arrangement of fibers in the structure, this type of material has a limited liquid conduction rate in the atomization matrix system, low liquid conduction efficiency, and is prone to core sticking, resulting in an excessively high residual night rate. Therefore, the present application provides a liquid storage component structure and a preparation method that can improve the liquid conduction capacity of the liquid storage component, which is described below with multiple embodiments.

[0041] Please refer to Figure 1 , one embodiment of the present application provides a liquid storage component for use in an atomization device.

[0042] The liquid storage element includes a main body 10 and a plurality of lyophilic parts 20. The lyophilic parts 20 are arranged in the main body 10. The main body 10 is formed with through holes 30. ， The through hole 30 is used as an atomization airway;

[0043] The plurality of lyophilic portions 20 are distributed outwardly in a divergent manner with the through hole 30 as the center, and the lyophilic portions 20 are connected to the through hole 30 ; the liquid conduction rate of the lyophilic portions 20 for the atomized matrix is ​​higher than that of the main body 10 .

[0044] In this embodiment, the main body 10 is the main part of the liquid storage part, and a through hole 30 is arranged inside, which is used to cooperate with the atomizing core in the atomizing device for atomization. The lyophilic part 20 is a liquid-conducting structure in the liquid storage part, which can further improve the liquid-conducting ability of the liquid storage part. Specifically, in terms of materials, the lyophilic part 20 adopts a material with a better liquid-conducting rate for the atomizing matrix than the main body 10, so that it has a higher affinity for the atomizing matrix than the main body 10. In terms of structure, the lyophilic part 20 is arranged to be connected to the through hole 30, so that the lyophilic part 20 can contact the atomizing core in the through hole 30. Since the lyophilic part 20 is distributed outwardly with the through hole 30 as the center, it ensures that the liquid-conducting part 50 is in continuous contact with the main body 10 during use, thereby improving the liquid-conducting ability of the liquid storage part, and the residual liquid rate can be reduced to less than 10% at most. It can solve the problem of high residual liquid rate of existing liquid storage materials.

[0045] It should be noted that the "liquid" and "atomization matrix" described in the present application are an aerogel matrix that can be atomized. The aerogel matrix can be atomized during the heating process. In an example, the aerogel matrix is ​​cigarette oil. Therefore, the liquid conduction rate in the present application also includes the oil conduction rate.

[0046] In one example, the main body 10 is a liquid storage cotton. In another example, the main body 10 is an oil storage cotton.

[0047] In one embodiment, Figure 1 As shown, the divergent distribution is as follows: one end of the plurality of lyophilic portions 20 is connected to the through hole 30 , and the other end of the lyophilic portion 20 extends in a direction away from the through hole 30 .

[0048] During the use of this embodiment, the divergently distributed multiple lyophilic portions 20 can increase the contact area with the main body 10, thereby more quickly and continuously infiltrating and absorbing the atomized matrix stored in the main body 10. The atomized matrix of the main body 10 in the liquid storage part can quickly reach the through hole 30 through the lyophilic portion 20 to contact the atomizing core and be atomized, thereby improving the liquid consumption efficiency and utilization rate of the liquid storage part. Since the contact area is increased, the residual liquid rate of the main body 10 can be reduced to avoid core sticking. It should be noted that in order to ensure the integrity of the liquid storage part, the lyophilic portion 20 should be separated from the outer wall of the liquid storage part by a certain distance.

[0049] In one embodiment, as shown in the attached Figure 2 As shown, the divergent distribution is: a plurality of divergently distributed lyophilic portions 20 are arranged around the through hole 30 , and the lyophilic portions 20 are connected to the through hole 30 .

[0050] During use of this embodiment, as in the above-mentioned embodiment, the lyophilic portion 20 disposed around the through hole 30 and connected to the through hole 30 can also increase the contact area with the main body 10, and more quickly and continuously infiltrate and absorb the atomized matrix stored in the main body 10.

[0051] In this embodiment, the lyophilic portion 20 disposed around the through hole 30 is not limited to a specific shape. The following is an explanation with some examples:

[0052] For an example, see Figure 2 , the lyophilic portion 20 disposed around the through hole 30 is arc-shaped. Figure 3 As shown, a plurality of arc-shaped lyophilic portions 20 may be disposed in the main body 10 in sequence from the inside to the outside surrounding the through hole 30 .

[0053] In another example, see Figure 3 The lyophilic portion 20 disposed around the through hole 30 is in the shape of a zigzag line with multiple sections continuously connected.

[0054] In another example, see Figure 4 The lyophilic portion 20 disposed around the through hole 30 is in the shape of multiple continuously connected arcs.

[0055] In another example, see Figure 5 The lyophilic portion 20 disposed around the through hole 30 is circular or elliptical and is sequentially disposed from the inside to the outside in the main body 10 .

[0056] It should be noted that the divergent distribution shapes of the lyophilic portion 20 in the above embodiments or examples can be arranged in any combination, and the present application does not limit the shapes in the above embodiments or examples to be arranged alone.

[0057] Next, the connection structure between the lyophilic portion 20 and the through hole 30 is further optimized in the case where a plurality of lyophilic portions 20 are arranged around the through hole 30 and the lyophilic portion 20 is connected to the through hole 30:

[0058] In one embodiment, please refer to Figure 6 , a liquid-conducting channel 40 is provided in the liquid storage member, one end of the liquid-conducting channel 40 is connected to the through hole 30, and the other end of the liquid-conducting channel 40 is connected to the lyophilic portion 20; or / and, please refer to Figure 7 A liquid guide portion 50 is provided in the liquid storage component, one end of the liquid guide portion 50 is connected to the through hole 30, and the other end of the liquid guide portion 50 is connected to the lyophilic portion 20; and the liquid guide portion 50 has a higher liquid guide rate for the atomized matrix than the main body 10.

[0059] Among them, the liquid guide channel 40 can guide the atomized matrix in the lyophilic part 20 to the through hole 30 for atomization, or the liquid guide cotton in the atomization core is extended into the liquid guide channel 40, and then contacts with multiple lyophilic parts 20. Similarly, the liquid guide part 50 can also guide the atomized matrix in the lyophilic part 20 to the through hole 30 for atomization. The two can be set separately or in combination.

[0060] In one example, the liquid guide channel 40 is a slit. When in use, the liquid storage member is cut along the direction of the through hole 30, and the liquid guide cotton of the atomizer core can extend from the slit to contact the lyophilic portion 20, so that the liquid guide cotton extending from the atomizer core contacts each layer of the lyophilic portion 20.

[0061] In another example, see Figure 7 The material of the liquid-conducting portion 50 is the same as that of the lyophilic portion 20, and then at one end of the communicating through hole 30, the liquid-conducting portion 50 adopts the same material as that of the lyophilic portion 20, which can further increase the proportion of the material with a better liquid-conducting rate for the atomized matrix relative to the main body 10 in the main body 10, thereby increasing the contact area between the material and the main body 10, so that it can better absorb the atomized matrix in the main body 10 and better guide the atomized matrix into the through hole 30 for atomization.

[0062] In the above example, the number of liquid-conducting channels 40 and liquid-conducting portions 50 is not limited. No matter which connection method is used, it is only necessary to ensure that the lyophilic portion 20 is distributed in the main body 10 and is in continuous contact with the liquid-conducting cotton of the atomizer core in the through hole 30 during use.

[0063] In one embodiment, one end of the lyophilic portion 20 communicating with the through hole 30 or one end of the liquid-conducting portion 50 communicating with the through hole 30 extends out of the through hole 30; the extending length of the lyophilic portion 20 or the liquid-conducting portion 50 extending out of the through hole 30 is 0.2 mm-1 mm.

[0064] In this embodiment, one end of the lyophilic portion 20 or the liquid-conducting portion 50 connected to the through hole 30 is extended out of the through hole 30, so that it can further fully contact the liquid-conducting cotton of the atomizer core in the through hole 30, thereby improving the atomization efficiency. In one example, the extended length includes 0.2 mm, 0.5 mm, 0.8 mm and 1 mm.

[0065] In one embodiment, a plurality of lyophilic portions 20 are arranged in an arc shape around the through hole 30 , and the central angle of the arc lyophilic portion 20 is 180°-320°.

[0066] In one example, the central angle of the lyophilic portion 20 includes 180°, 200°, 250°, 270°, 300°, and 320°.

[0067] In one embodiment, the lyophilic portion 20 is made of a non-woven fabric material, and the non-woven fabric material includes a blend of one or more of cotton fiber, linen fiber, viscose fiber, tencel fiber, and cuprammonia fiber.

[0068] The non-woven fabric material mentioned above includes natural fibers and artificial synthetic fibers, and the non-woven fabric material has a higher lyophilicity than other materials of the main body 10 .

[0069] In one example, the non-woven fabric material has a grammage of 45 to 120 g.

[0070] In one example, the volume density of the liquid storage element ranges from 0.04 to 0.08 g / cm 3 .

[0071] In one embodiment, the material of the main body 10 is fiber precursor, and the fiber precursor includes one or more of PP, PE, PET, and PA.

[0072] In one example, the fiber strands are subjected to a texturing process.

[0073] In one example, the diameter of the fiber filament is 10-30 um.

[0074] In one embodiment, the main body 10 includes a skin layer and a core layer, and the skin layer is arranged outside the core layer. The main body 10 is arranged as a skin-core structure with inner and outer layers, so that it can have different melting points, so as to facilitate heating and molding.

[0075] In one example, the skin layer is made of PA material, and the core layer is made of PET material.

[0076] Please refer to Fig. 9 Another embodiment of the present application provides a method for preparing a liquid storage component, further comprising:

[0077] Step S10: combining the coiled material of the lyophilic portion 20 and the raw material of the main body 10 in a preset arrangement order to obtain a liquid storage component raw material;

[0078] Step S20: The liquid storage component raw material is subjected to thermoforming, and the through hole 30 of the liquid storage component is formed by a mold during the thermoforming process to obtain a liquid storage component finished material;

[0079] Step S30 : cutting the liquid storage component material to obtain a finished liquid storage component having the lyophilic portion 20 disposed in the main body 10 , the lyophilic portion 20 being distributed outwardly with the through hole 30 as the center, and the lyophilic portion 20 being connected to the through hole 30 .

[0080] Among them, step S10 is an important step in preparing the lyophilic part 20. The role of the preset arrangement order is to obtain the divergent distribution shape of the required lyophilic part 20. The same method can also be used to obtain the liquid-conducting part 50 according to actual needs. Therefore, in the actual preparation process, the arrangement order can be preset according to the actual shape design requirements of the lyophilic part 20. At the same time, the preset arrangement order also ensures that the lyophilic part 20 can be connected with the through hole 30 during the subsequent thermoforming process. Step S20 is an important step in preparing the through hole 30. The through hole 30 of the liquid storage part is formed by the mold in the thermoforming. For example, a rod-shaped object used to hinder the raw material flowing due to heat can be set in the mold to form the required through hole 30. The subsequent cutting process can eliminate the step of cutting the through hole 30, thereby improving the efficiency of preparation. Step S30 is the final step. The final liquid storage part of suitable size and shape is obtained by cutting. It can be understood that the size and shape of the liquid storage part can be cut according to actual needs during the cutting process.

[0081] This embodiment can solve the problem of mass production of the above-mentioned liquid storage components, and provides a set of mass production process flows based on the existing production process.

[0082] Please refer to Fig.10 Another embodiment of the present application further refines the above-mentioned preparation method, and the preparation method further comprises the following steps:

[0083] Step S01: cutting the non-woven fabric material, and then rolling it up for standby use to obtain a non-woven fabric roll;

[0084] Step S11: placing the non-woven fabric rolls on a material tray together with the fiber precursors in a preset arrangement order, and sequentially drying and yarn combining to obtain a liquid storage component raw material;

[0085] Step S21: placing the liquid storage component raw material in a thermoforming device for molding, and then cooling it to obtain a liquid storage component finished material, wherein during the thermoforming process, a through hole 30 of the liquid storage component is formed by a mold;

[0086] Step S30 : cutting the liquid storage component material to obtain a finished liquid storage component having the lyophilic portion 20 disposed in the main body 10 , the lyophilic portion 20 being distributed outwardly with the through hole 30 as the center, and the lyophilic portion 20 being connected to the through hole 30 .

[0087] After determining that the material of the lyophilic portion 20 is a nonwoven material, step S01 may be a pre-step of step S10. In step S01, slitting may be performed by means of a slitting device, the purpose of slitting is to cut into a required width size, and winding may be performed by a collection roller.

[0088] Among them, step S11 is a further alternative optimization step of step S10 after using the non-woven fabric material of the lyophilic part 20. In this step, according to specific design requirements, the structure generated by the preset arrangement order of the non-woven fabric roll includes the material of the lyophilic part 20 and the liquid-conducting part 50 using the same material. In step S11, the arrangement order of the non-woven fabric roll on the material tray determines the distribution state of the lyophilic part 20 in the main body 10. The fiber precursor can be selected from the fiber precursor treated by the elasticization process, and different types of fiber precursors can also be selected to obtain the main body 10 of the skin-core structure, so that the inner and outer layers have different melting points, so as to facilitate heating and molding. In addition, the drying step is because the non-woven fabric material has a regain, and its water absorption rate is generally above 8%. It needs to be dried before molding to make the moisture content lower than 0.5%, otherwise it may cause the fiber precursor to fail to bond when molding together with the fiber precursor.

[0089] Among them, step S21 is a further alternative optimization step of step S20 after using the non-woven fabric material of the lyophilic part 20. In step S21, the thermoforming can be performed by a thermoforming device. The dried yarn fiber enters the mold of the thermoforming device under the action of drafting, and is cooled after molding. In step S30, it can be cut according to the demand after cooling.

[0090] In one embodiment, the main body 10 of the liquid storage device includes a skin layer and a core layer, and the skin layer is arranged outside the core layer. In the preparation process, PET is selected as the core layer and PA is selected as the elastic fiber precursor of the skin layer. The fiber diameter is 15-18um. The fiber precursor is placed on the material tray, and after the yarn is combined, it is formed by a thermoforming device and cut after cooling. The volume density is 0.056g / cm 3 .

The same atomizing matrix and atomizing device are selected, the amount of the atomizing matrix added is kept consistent, the suction power is kept consistent, and the weight of the atomizing device is tested after every 50 puffs, and the TPM is calculated. When the TPM data is lower than 5 mg / puff, the residual liquid rate is calculated by weighing, and the formula is as follows:

[0111] Residual liquid rate % = (weight of atomizer after suction - weight of atomizer without liquid injection) / total liquid injection amount * 100%.

[0112] The experimental results are as follows:

[0113] Group Residual liquid rate Comparative Example 30％ Example 1 15％ Example 2 8％ Example 3 10％

[0114] It can be seen from the experimental results that the residual liquid rate of Examples 1 to 3 is significantly lower than that of the comparative example, and the residual liquid rate of the liquid storage member is reduced.
