Abstract
Description
Technical Field
[0001] The present invention relates to the technical field related to electronic cigarettes, and in particular to a method for evaluating residual tobacco oil in an integrated cotton ball of an electronic cigarette. Background Art
[0002] The evaluation of the residual e-liquid in the integrated cotton is mainly used to evaluate the amount of e-liquid consumed by the heating core from the start of operation to the core burning, and then to determine the number of puffs a user can normally take on the e-cigarette.
[0003] At present, the common evaluation method in the industry is to test the final residual amount after normal smoking with a smoking machine. First, the electronic cigarette is assembled normally according to the product standard. The weight of the integrated cotton G1 is recorded before assembly. After assembly, the integrated cotton will be injected with the standard amount of tobacco oil required by the product and weighed and recorded G2; then the standard electronic cigarette is smoked through the smoking machine according to the smoking standard until the smoking is completed; finally, the electronic cigarette is disassembled and the integrated cotton is weighed and recorded G3; the tobacco oil usage rate is calculated as follows (the current default usage rate in the industry is about 75%): usage rate = (G2-G3) / (G2-G1)*100%. This method has the following disadvantages: it requires the consumption of a certain amount of materials, and the product testing process is irreversible, resulting in a certain amount of waste; it takes a long time, from material collection, assembly, testing to final disassembly, it takes at least one week; it requires more manpower, and the entire testing process involves many professions, resulting in a waste of human resources.
[0004] Therefore, it is necessary to provide a method for evaluating the residual oil in the integrated cotton of an electronic cigarette to solve the problems in the prior art. Summary of the Invention

[0010] Step S4: injecting the e-liquid described in step S1 into the integrated cotton and allowing the e-liquid to be adsorbed to a saturated state in the integrated cotton. The e-liquid is then weighed and marked with a weight M3. At this point, the sample is prepared;
[0011] Step S5: Separate the two pieces of non-woven fabrics described in step S2 into left and right parts, then vertically place the sample described in step S4 on the filter paper described in step S1 and let it stand for 6 to 8 hours;

[0024] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0025] Please see Figure 1-3 In an embodiment of the present invention, a method for evaluating residual e-cigarette oil in an integrated cotton swab comprises the following steps:
[0026] Step S1: Prepare relevant materials, PC tube 1, integrated cotton 2, oil-conducting cotton, cotton-wrapped swab, 2 pieces of linen non-woven fabric 3, filter paper 5, and e-liquid;
[0027] Step S2: Assemble the oil-conducting cotton, the cotton-wrapped rod, and two pieces of linen non-woven fabrics 3 in sequence, so that the oil-conducting cotton is perpendicular to the cotton-wrapped rod, and the linen non-woven fabrics 3 are parallel to the cotton-wrapped rod. The oil-conducting cotton needs to be wrapped with the linen non-woven fabric 3 before being assembled into the atomizing core 4, so that the linen non-woven fabric 3 is close to the cotton-wrapped rod;
[0028] Step S3: Weigh the integrated cotton and record the weight M1. Then, assemble the atomizer core 4 described in step S1 into the integrated cotton 2. Finally, assemble the integrated cotton 2 with the atomizer core 4 into the PC tube 1 and weigh it, recording the weight M2.
[0029] Step S4: inject the e-liquid described in step S1 into the integrated cotton 2, and allow the e-liquid to be adsorbed to a saturated state in the integrated cotton 2. Then weigh it and mark the weight M3. At this point, the sample is prepared.
[0030] Step S5: Separate the two pieces of linen non-woven fabric 3 described in step S2 into the left and right parts. Then, vertically place the sample described in step S4 on the filter paper 5 described in step S1 and let it stand for 6 to 8 hours before conducting the experiment. Due to the wicking effect of the oil-conducting cotton and the non-woven fabric, the smoke oil in the integrated cotton 2 will slowly transfer to the filter paper 5. By regularly replacing the filter paper 5, the smoking effect of an electronic cigarette can be fully simulated.
[0031] Step S6: After the experiment is completed, the integrated cotton 2 is taken out, weighed, and marked with the weight M4;
[0032] Step S7: Calculate the residual rate according to the residual rate calculation formula: residual rate = (M4-M1) / (M3-M2)*100% to obtain the residual rate of the e-liquid.
[0033] Preferably, the length of the PC tube 1 in step 1 is 5 cm greater than the length of the integrated cotton.
[0034] Preferably, the filter paper 5 in step 1 is set to be a blended fiber of cotton fiber and hemp fiber with a mass percentage content of 50% respectively.
[0035] Preferably, the linen non-woven fabric in step 1 is provided as a single-layer linen non-woven fabric.
[0036] Preferably, the number of the linen non-woven fabrics in step 1 is set to 2 pieces.
[0037] Design principle: The present invention selects a filter paper with a blended fiber of 50% cotton fiber and 50% hemp fiber as the base material, which is consistent with the cotton core. Through the existing linen non-woven fabric, a channel is established between the cotton core and the filter paper. The wicking effect of the non-woven fabric is used to transfer the tobacco oil in the integrated cotton to the filter paper, thereby realizing the extraction of the tobacco oil in the integrated cotton. Thus, the effect of simulating smoking is achieved; then, by replacing the filter paper, the final extraction of the tobacco oil can be completed. Finally, a criterion for determining whether the tobacco oil extraction is completed is formulated, that is, the weight change of the new filter paper replaced within 10 seconds is less than 0.007g (the amount of tobacco oil required for a normal puff). After the test is completed, it can be weighed and the usage rate can be calculated.
[0038] Example 1
[0039] In the embodiment of the present invention, the Figure 1-3 The product shown in the figure has an outer diameter of 22.1±0.5 mm. After being assembled in sequence according to steps S2-S7 of the electronic cigarette integrated cotton smoke oil residue evaluation method of the present invention, the smoke oil residue test was performed. At the same time, the product was assembled and tested according to a conventional method, and the average value of each group was taken. After completion, the comparison was performed. The oil injection volume of the product was 5.5 ml and the density was 1.12 g / cm3.
[0040] The present invention provides an electronic cigarette integrated cotton oil residue evaluation method, and the relevant results are as follows:
[0041]
[0042]
[0043] The calculation formula is as follows:
[0044] Residual rate = (M4-M1) / (M3-M2)*100%
[0045] The test was carried out using conventional methods, and the test results are as follows:
[0046] Serial number Cotton weight (g) M1 Cotton weight after core paste (g) M2 Residual rate 1 0.508 2.280 28.77% 2 0.508 2.000 24.22% 3 0.508 2.123 26.22% 4 0.508 2.235 28.04% 5 0.508 2.315 29.33%
[0047] The calculation formula is as follows:
[0048] Residual rate = (M2-M1) / 5.5*1.12
[0049] Comparing the experimental results of the two methods above, we can see that the test result of the electronic cigarette integrated cotton oil residual evaluation method of the present invention is 24.62%, while the test result of the conventional method is 27.31%. The test results of the two methods are basically consistent, indicating that the experimental method can serve as an alternative to the conventional method. At the same time, the lower test results of the experimental method are mainly due to the more gentle experimental process compared to the conventional method, which completely relies on the material's inherent wicking ability to simulate the test.
[0050] The above detailed description is a specific description of one feasible embodiment of the present invention. However, the embodiment is not intended to limit the patent scope of the present invention. Any equivalent implementation or modification that does not depart from the technical spirit of the present invention should be included in the patent scope of this case.
