[0039] The display liquid containing chamber 3 has a height of 15.5 cm-42.5 cm, a length of 1.5 mm-102 mm, and a width of 1.5 mm-102 mm.

[0040] Compared with the absorption speed tester in the prior art, the portable sanitary product absorption speed demonstration device in the utility model is small in size and easy to carry; the portable sanitary product absorption speed demonstration device in this embodiment is used as follows: the liquid outlet 4 is fitted with the sanitary product to be tested, the demonstration liquid is poured from the liquid injection port 2, and the liquid level descending speed and time of the demonstration liquid in the demonstration liquid containing chamber 3 are observed, so as to compare the absorption capacity and absorption speed between different sanitary products, and the absorption speed performance of the sanitary products is visualized; compared with the absorption speed tester in the prior art, there is no problem of precision electrode oxidation, which greatly reduces the maintenance cost of the device.

[0041] like Figure 2 As shown, further, the flow rate display module 1 includes an upper display module 11 and a lower display module 12;

[0042] The liquid injection port 2 is provided on the upper display module 11;

[0043] The liquid outlet 4 is provided on the lower display module 12;

[0044] The upper display module 11 and the lower display module 12 are detachably connected, which is convenient for disassembly, carrying and transportation.

[0045] Specifically, the lower display module 12 is provided with an installation cavity 121 for installing the upper display module 11. The inner diameter of the installation cavity 121 is equal to the outer diameter of the upper display module 11, and the upper display module 11 is inserted into the installation cavity 121 for installation.

[0046] More specifically, the depth of the installation cavity 121 is smaller than the height of the upper display module 11; when in use, a portion of the upper display module 11 is embedded in the installation cavity 121, and the other portion is exposed outside the lower display module 12; when separating the upper display module 11 and the lower display module 12, the portion of the upper display module 11 exposed outside can be used as a handheld part for leveraging to remove the upper display module 11 from the lower display module 12.

[0047] More specifically, the upper display module 11 is cylindrical, 20 cm high, 12 mm in outer diameter, 6 mm in inner diameter, and 3 mm in wall thickness;

[0048] The lower display module 12 is in the shape of a cube, with a length of 20 cm, a width of 10 cm and a height of 2 cm.

[0049] More specifically, a cylindrical first display liquid containing chamber 31 is provided in the upper display module 11, and the first display liquid containing chamber 31 is connected to the liquid injection port 2;

[0050] The lower display module 12 is further provided with a second display liquid containing chamber 32 communicating with the installation chamber 121, and a third display liquid containing chamber 33 communicating with the second display liquid containing chamber 32; the second display liquid containing chamber 32 is cylindrical, the third display liquid containing chamber 33 is cubic, and the liquid outlet 4 is communicated with the third display liquid containing chamber 33;

[0051] The first display liquid containing chamber 31 , the second display liquid containing chamber 32 and the third display liquid containing chamber 33 together constitute the display liquid containing chamber 3 .

[0052] The first display liquid containing chamber 31 and the second display liquid containing chamber 32 are cylindrical, which can reduce the resistance of the sanitary product to absorb the display liquid; and the process is relatively simple during processing; the third display liquid containing chamber 33 and the liquid outlet 4 are in a cubic shape. Taking the test sanitary napkin as an example, its transverse and longitudinal absorption speed capabilities are inconsistent, and the cubic design has the effect of spreading the display liquid in the transverse and longitudinal directions on the contact surface of the sanitary product to be tested, which is suitable for testing sanitary products with inconsistent transverse and longitudinal absorption speed capabilities; of course, it is also applicable to sanitary products with consistent transverse and longitudinal absorption speed capabilities, and has strong versatility.

[0053] More specifically, the diameter of the first display liquid containing chamber 31 is larger than the diameter of the second display liquid containing chamber 32; the flow rate of the liquid is inversely proportional to the cross-sectional area of ​​the pipe through which it flows, so the diameter of the second display liquid containing chamber 32 is smaller than the first display liquid containing chamber 31, which helps to reduce the flow rate of the display liquid in the second display liquid containing chamber 32, making it easier to observe.

[0054] More specifically, the first display liquid containing chamber 31 and the second display liquid containing chamber 32 are coaxially arranged to reduce the flow resistance of the display liquid.

[0055] More specifically, the axis of the second display liquid containing chamber 32 is coaxial with the intersection of two diagonal lines of the third display liquid containing chamber 33 to further reduce the flow resistance of the display liquid.

[0056] Specifically, the first display liquid containing chamber 31 has a height of 15 cm to 40 cm and a diameter of 3 mm to 10 mm;

[0057] The height of the installation cavity 121 is 5 mm to 15 mm, and the diameter is 7.5 mm to 16.5 mm;

[0058] The second display liquid containing chamber 32 has a height of 4.5-20 mm and a diameter of 1.5 mm-6 mm;

[0059] The third display liquid containing chamber 33 has a height of 0.5 mm to 5 mm, a length of 16 mm to 102 mm, and a width of 2 mm to 8 mm.

[0060] More specifically, the first display liquid containing chamber 31 has a height of 20 cm and a diameter of 6 mm;

[0061] The height of the installation cavity 121 is 8 mm and the diameter is 12±0.5 mm;

[0062] The second display liquid containing chamber 32 has a height of 10.5 mm and a diameter of 2±0.2 mm;

[0063] The third display liquid containing chamber 33 has a height of 1.5 mm, a length of 32 mm, and a width of 2 mm.

[0064] More specifically, the flow rate display module 1 is made of a transparent material, so that the speed at which the liquid level of the display liquid in the flow rate display module 1 drops can be easily observed.

[0065] More specifically, the flow rate display module 1 is made of PMMA. The portable sanitary product absorption rate demonstration device made of PMMA has the advantages of being not fragile, easy to store, small in size, small in weight, easy to carry, and low in production cost.

[0066] In the portable sanitary product absorption speed demonstration device of this embodiment, taking sanitary napkin as an example, the height of the first display liquid holding chamber 31 of the test device is 20 cm and the diameter is 6 mm; the height of the installation chamber 121 is 8 mm and the diameter is 12±0.5 mm; the height of the second display liquid holding chamber 32 is 10.5 mm and the diameter is 2±0.2 mm; the height of the third display liquid holding chamber 33 is 1.5 mm, the length is 32 mm, and the width is 2 mm;

[0067] The absorption rate of the product is measured from the moment the liquid is poured into the cylindrical tube, and the measurement is stopped when the liquid completely penetrates into the sanitary napkin.

[0068] Products A, B, C, and D were all purchased from the market and were demonstrated using standard synthetic fluids. The standard synthetic fluids used in this test were prepared with reference to Appendix B of GB / T8939-2018 Sanitary Napkins (Pads);

[0069] In order to prove that the portable sanitary product absorption speed demonstration device in this embodiment can compare the absorption capacity of different sanitary products, the absorption speed tester T017 of China Paper Research Institute is used as a reference; the absorption speed tester is used to test the absorption speed of product A, product B, product C and product D in accordance with Appendix A of GB / T8939-2018 Sanitary Napkin (Pad) and the experimental data obtained are shown in Table 1:

[0070]

[0071] Table 1

[0072] It can be seen from Table 1 above that whether it is the portable sanitary product absorption rate demonstration device in this embodiment or the absorption rate measuring instrument, the absorption rates of product A, product B, product C and product D are detected to be ranked as follows: product D>product C>product A>product B.

[0073] Therefore, the portable sanitary product absorption speed demonstration device provided by the utility model is used to compare the absorption capacity and absorption speed of different sanitary products, so as to help understand the product performance of different sanitary products.
