Description

Technical Field

[0001] This invention relates to the field of electronic atomization technology, and in particular to a method for testing the performance of an oil-conducting medium. Background Technology

[0002] Electronic cigarettes are products that use atomization to turn nicotine and other substances into an aerosol for people to inhale. The most common method is to use wicking cotton to absorb the e-liquid and then atomize it into an aerosol.

[0003] As the market offers a wider variety of e-cigarette products, flavor has become a crucial factor for consumers, leading to increasingly higher demands for vaping experiences. Flavor is closely related to the wicking mechanism; the wicking and retention properties of the wicking cotton significantly impact the taste. Currently, most common testing methods for wicking cotton are limited to measuring size, weight, and density, lacking in-depth testing methods for physicochemical properties. This is especially true for materials with excessively high wicking rates, as the inability to accurately determine these rates results in inconsistent quality of e-cigarettes and a poor consumer experience. A few methods exist that delve deeper into the physicochemical properties of wicking cotton, testing its weight, wicking rate, and retention capacity to achieve higher accuracy in determining the wicking rate.

[0004] However, the flavor tuning of an atomizer is mainly achieved by combining different wicking media and adjusting the compression ratio. Test data in the uncompressed state cannot provide a reference or basis for tuning. Summary of the Invention

[0005] Therefore, it is necessary to provide a performance testing method for the oil guiding medium under compression during the actual taste adjustment process to address the above problems. This method can make the test results closely match the actual adjustment parameters, greatly shorten the time required for taste adjustment, and make the taste adjustment more stable.

[0006] A method for testing the performance of an oil-conducting medium includes the following steps:

[0007] S1. Prepare N layers of oil-conducting medium of type A with a width of W and a length of L, and obtain the thickness δ of the N layers of oil-conducting medium;

[0008] S2. Assemble the test sample by placing N layers of oil-conducting medium with a width of W around a central rod with an outer diameter of d, and then placing the oil-conducting medium and the central rod together into a rigid tube with an inner diameter of D.

[0009] S3. Obtain the compression ratio ε of the test sample, where:

[0010] S4. Obtain the weight m0 of the test sample in the initial state;

[0011] S5. Place an appropriate amount of e-liquid into a measuring cup;

[0012] S6. Fix the upper end of the rigid tube with a clamping fixture, vertically immerse the oil-absorbing section of the test sample into the e-liquid, and simultaneously time t to remove the test sample and weigh it m1.

[0013] S7, Calculate the oil transfer rate Calculate oil storage ratio

[0014] In one embodiment, n sets of N layers of oil guiding medium with width W and length L are prepared, along with n sets of central rods with outer diameter d and rigid tubes with inner diameter D. The corresponding data are recorded according to steps S1 to S7, and the average compression ratio of the n test samples is measured. Average oil transfer rate of n groups of test samples: Average oil storage rate of n groups of test samples:

[0015] In one embodiment, the oil-guiding medium is a single type of oil-guiding cotton or a combination of different types of oil-guiding cotton; the rigid tube is a rigid transparent tube.

[0016] In one embodiment, the width W of the oil guiding medium is in the range of 5mm ≤ W ≤ 70mm, the inner diameter D of the rigid tube is in the range of 3mm ≤ D ≤ 10mm, and the outer diameter d of the central rod is in the range of 1mm ≤ d < D.

[0017] In one embodiment, the width W of the oil guiding medium is in the range of 20mm≤W≤50mm, the inner diameter D of the rigid tube is in the range of 5mm≤D≤8mm, and the outer diameter d of the central rod is in the range of 1mm≤d<D.

[0018] In one embodiment, the compression ratio ε of the assembled oil guiding medium is in the range of 0 ≤ ε < 1.

[0019] In one embodiment, the oil absorption time t is in the range of 10s≤t≤300s.

[0020] In one embodiment, the rigid transparent tube includes an insertion section and an oil suction section connected together. The insertion section is provided with an operating groove. The oil guiding medium is inserted through the operating groove after surrounding the central rod. Then, the central rod is pushed to move the oil guiding medium to be flush with the free end of the oil suction section.

[0021] In one embodiment, steps S2 and S3 for obtaining the compression ratio ε can be replaced by:

[0022] S2' Assemble the test sample. Spread the oil guiding medium evenly in the "U"-shaped fixture with a depth of h. Press the "U"-shaped fixture with a cover plate in the opening direction and fix the cover plate.

[0023] S3', Obtain the compression ratio ε of the test sample, where:

[0024] In one embodiment, step S7, which calculates the oil conduction rate V and oil storage rate G at the compression ratio ε of the n-layer oil guiding medium, can be replaced by:

[0025] S7' Calculate the oil guiding rate Calculate oil storage ratio

[0026] The above-mentioned performance testing methods for oil guiding media have at least the following advantages:

[0027] This method for testing the performance of the wicking medium involves detecting and calculating the weight, compression ratio, wicking rate, and oil storage rate of the wicking medium under compression during actual flavor tuning. This allows the test results to closely match the actual tuning parameters, significantly shortening the time required for flavor tuning and making the tuning more stable. Furthermore, it allows setting different compression ratios and measuring the wicking and oil storage performance of the wicking medium under different compression ratios, providing quantitative data and direction for atomizer flavor tuning.

[0038] Implementation Method 1:

[0039] Please see Figure 1 A method for testing the performance of an oil-conducting medium 12 includes the following steps:

[0040] S1. Prepare N layers of oil-conducting medium 12 of type A with width W and length L, and obtain the thickness δ of the N layers of oil-conducting medium 12; wherein, 1≤N≤10, preferably 5 to 6 layers; 5mm≤W≤70mm, preferably 20mm≤W≤50mm; 5mm≤L≤70mm, preferably 20mm≤L≤50mm. W, L and δ are measured using electronic calipers with an accuracy of 0.01mm.

[0041] S2. Assemble the test sample 10. Surround the central rod 14 with an outer diameter of d with N layers of oil-conducting medium 12 with a width of W. Then, place the oil-conducting medium 12 and the central rod 14 together into the rigid tube 16 with an inner diameter of D. Wherein, 3mm≤D≤10mm, preferably: 5mm≤D≤8mm; 1mm≤d<D. D is measured by a thickness gauge, and d is measured by an electronic caliper with an accuracy of 0.01mm.

[0042] S3. Obtain the compression ratio ε of the test sample 10, where: Substitute the measured data into the calculation formula to obtain the compression ratio; the compression ratio ε after the oil guide medium 12 is assembled is in the range of 0≤ε<1.

[0043] S4. Obtain the weight m0 of the test sample 10 in its initial state; m0 is measured using a weighing instrument with an accuracy of 0.001g.

[0044] S5. Place an appropriate amount of e-liquid in a measuring cup; specifically, place 200ml to 400ml of e-liquid in a 500ml measuring cup and let it stand for at least 20 seconds; of course, you can also place the e-liquid in the measuring cup and let it stand before any step before S5.

[0045] S6. Fix the upper end of the rigid tube 16 with a clamping fixture, vertically immerse the oil absorption section 164 of the test sample 10 into the e-liquid, and take out the test sample and weigh m1 at the same time t; wherein, 10s≤t≤300s, preferably: 100s≤t≤150s, and a stopwatch is used for timing; m1 is measured by a weighing instrument with an accuracy of 0.001g.

[0046] S7, Calculate the oil transfer rate Calculate oil storage ratio Substituting the measured data into the calculation formula, the oil conduction rate and oil storage rate of the test sample 10 assembled from oil-conducting medium 12 of type A are obtained.

[0047] The performance testing method for the wicking medium 12 involves detecting and calculating its weight, compression ratio, wicking rate, and e-liquid storage rate under compression during actual flavor tuning. This ensures that the test results closely match the actual tuning parameters, significantly reducing the time required for flavor tuning and making the tuning more stable. Furthermore, different compression ratios can be set to measure the wicking and e-liquid storage performance of the wicking medium 12 at different compression ratios, providing quantitative data and direction for atomizer flavor tuning. Specifically, within the compression ratio range of 0 ≤ ε < 1, different compression ratios can be set according to testing requirements and actual usage scenarios, measuring the wicking and e-liquid storage performance of the wicking medium 12 at different compression ratios, providing quantitative data and direction for atomizer flavor tuning.

[0048] The performance testing method of this wicking medium 12 is not only applicable to the A-type wicking medium 12, but also to other different types of wicking media 12, and even to multiple wicking media 12 mixed according to a certain rule. It can measure and record the wicking performance and oil storage performance of different wicking media 12 in single or combined states and under different compression ratios, providing quantitative data and direction for atomizer flavor tuning, improving flavor stability, and greatly shortening the time required for flavor tuning.

[0049] In this embodiment, to ensure the stability of the measurement data and the validity of the results, S8 is also included: preparing n sets of N layers of oil guiding medium 12 with a width of W and a length of L, and n sets of center rods 14 with an outer diameter of d and rigid tubes 16 with an inner diameter of D, and operating and recording the corresponding data according to the steps of S1 to S7, the average compression ratio of the n sets of test samples 10 can be measured: Average oil transfer rate of n groups of test samples:

[0050] Average oil storage rate of n groups of test samples: Of course, during the testing and calculation process, values ​​with a deviation greater than 10% were excluded from multiple sets of test data. This is understandable, as a deviation greater than 10% is practically impossible in normal measurement and calculation processes without errors. If such a deviation occurs, it indicates an error in a certain measurement or calculation step, and excluding that set of data suffices. The data here can include at least one of m0, m1, t, D, d, N, W, δ, ε, V, and G.

[0051] In this embodiment, the oil-guiding medium 12 is a single type of oil-guiding cotton or a combination of different types of oil-guiding cotton. When the oil-guiding medium 12 is a single type of oil-guiding cotton, such as all being N layers of type A oil-guiding cotton, all being N layers of type B oil-guiding cotton, or all being N layers of type C oil-guiding cotton, the performance of each layer of material is the same. The oil-guiding rate and oil storage rate performance data under different compression ratios can be used to provide a database for adjusting the taste stability and greatly reduce the adjustment time. When the oil-guiding medium 12 is a combination of different types of oil-guiding cotton, such as one layer of type A oil-guiding cotton + two layers of type B oil-guiding cotton alternately laid flat, one layer of type A oil-guiding cotton + one layer of type B oil-guiding cotton + one layer of type C oil-guiding cotton alternately laid flat, two layers of type B oil-guiding cotton + one layer of type C oil-guiding cotton alternately laid flat, or other combinations of different types and different numbers of oil-guiding cotton, different taste and capabilities can be achieved compared to a single oil-guiding cotton. The rigid tube 16 is a rigid transparent tube; its transparency allows for real-time observation of the degree to which the test sample 10 absorbs e-liquid, ensuring that the test sample 10 can absorb a relatively saturated amount of e-liquid to meet the test requirements.

[0052] Please see Figure 2 , Figure 3In this embodiment, the rigid transparent tube includes an insertion section 162 and an oil-absorbing section 164 connected to each other. The insertion section 162 is provided with an operating groove 166. The oil-conducting medium 12 is placed around the center rod 14 and then inserted through the operating groove 166. The center rod 14 is then pushed to move the oil-conducting medium 12 until it is flush with the free end of the oil-absorbing section 164. After the oil-conducting medium 12 wraps around the center rod 14, it is placed into the insertion section 162 of the rigid transparent tube. To facilitate hand operation, the length L is usually greater than the inner diameter of the rigid transparent tube. At this time, it is necessary to cut off the excess oil-conducting medium 12 along the inner diameter of the rigid transparent tube, and then push the oil-conducting medium 12 to the bottom, flush with the end face of the bottom oil-absorbing section 164 of the rigid transparent tube. The operating groove 166 facilitates hand operation and also makes it easier to reduce the excess hand part of the oil-conducting medium 12 to the same as the inner diameter of the rigid transparent tube, so that the measurement results are consistent with the actual use of the atomizer coil, making the data more valuable. Of course, the oil guiding medium 12 can also perfectly fit the outer diameter of the center rod 14 and the inner diameter of the rigid transparent tube without cutting.

[0053] Implementation Method Two:

[0054] Please see Figure 4 A method for testing the performance of an oil-conducting medium 22 includes the following steps:

[0055] S1. Prepare N layers of oil-conducting medium 22 of type A with width W and length L, and obtain the thickness δ of the N layers of oil-conducting medium 22; wherein, 1≤N≤10, preferably 5 to 6 layers; 5mm≤W≤70mm, preferably 20mm≤W≤50mm; 5mm≤L≤70mm, preferably 20mm≤L≤50mm. W, L and δ are measured using electronic calipers with an accuracy of 0.01mm.

[0056] S2' Assemble the test sample 20. Lay the oil guiding medium 22 flat in the U-shaped fixture 24 with a depth h. Press the U-shaped fixture 24 with a cover plate 26 in the opening direction and fix the cover plate 26. The thickness is 0.2mm ≤ h ≤ 10mm, preferably 1mm ≤ h ≤ 3mm. For the specific structure of assembling the test sample 20, please refer to [link / reference needed]. Figure 5 , Figure 6 .

[0057] S3′, Obtain the compression ratio ε of the test sample 20, where:

[0058] S4. Obtain the weight m0 of the test sample 20 in its initial state; m0 is measured using a weighing instrument with an accuracy of 0.001g.

[0059] S5. Place an appropriate amount of e-liquid in a measuring cup; specifically, place 200ml to 400ml of e-liquid in a 500ml measuring cup and let it stand for at least 20 seconds; of course, you can also place the e-liquid in the measuring cup and let it stand before any step before S5.

[0060] S6. Fix the upper end of the rigid tube with a clamping fixture, vertically immerse the oil absorption section of the test sample 20 into the e-liquid, and simultaneously time t to remove the test sample and weigh m1; wherein, 10s≤t≤300s, preferably: 100s≤t≤150s, and a stopwatch is used for timing; m1 is measured using a weighing instrument with an accuracy of 0.001g.

[0061] S7' Calculate the oil guiding rate Calculate oil storage ratio

[0062] In this embodiment, to ensure the stability of the measurement data and the validity of the results, S8 is also included: preparing n sets of N layers of oil guiding medium 22 with a width of W and a length of L, and n sets of "U"-shaped fixtures 24 with a groove depth of h, and operating and recording the corresponding data according to the steps of S1 to S7, the average compression ratio of the n sets of test samples 20 can be measured. Average oil transfer rate of n groups of test samples: Average oil storage rate of n test samples: Of course, during the testing and calculation process, values ​​with a deviation greater than 10% were excluded from multiple sets of test data. This is understandable because, in normal measurement and calculation processes, a deviation greater than 10% is practically impossible without errors. If it does occur, there must be an error in a certain measurement or calculation step, and that set of data can be excluded. The data here can include at least one of m0, m1, t, h, N, W, δ, ε, V, and G. Specific implementation examples:

[0064] Following the steps in Implementation Method 1, prepare 5 sets of 6 layers of Type A oil guiding medium 12 with a width W = 40 mm, and measure the thickness δ of the oil guiding medium 12 in its uncompressed state; prepare a rigid transparent tube with an inner diameter D = 5 mm and a center rod 14 with an outer diameter d = 2.5 mm, and assemble the test sample 10. The compression ratio can then be calculated. Initially weigh the test sample 10 and record the weight as m0. Prepare 300ml of e-liquid in a 500ml measuring cup and let it stand for 30s. Then, fix the upper end of the rigid tube with a clamping fixture, and vertically immerse the oil absorption section 164 (including the section containing the wicking medium 12) of the test sample 10 into the e-liquid. Simultaneously time t=120s, remove the test sample 10 and weigh it m1. Calculate the wicking rate. Calculate oil storage ratio Calculate the average compression ratio of n test samples 10 Average oil conduction rate of n groups of test samples 10 and the average oil storage rate of n test samples 10

[0065] Therefore, the following table can be obtained through measurement and calculation:

[0066]

[0067]

[0068] This invention measures the oil conduction rate and oil storage rate by setting different compression ratios for the oil conduction medium 12 and measuring the oil absorption of the oil conduction medium 12 under compression within a time difference. This measurement of the oil conduction and liquid storage performance of the oil conduction medium 12 is more in line with the parameters required for actual use, and provides quantitative data and direction for adjusting the flavor of atomizers.

For the sake of brevity, not all possible combinations of the technical features in the above 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.

[0070] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention.
