[0039] In order to make the objects, features and advantages of the present application more obvious and understandable, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0040] By analyzing the prior art, the inventors found that the conventional shoe mildew resistance test is to place the shoes in a constant temperature space and keep the humidity inside the constant temperature space at a humidity suitable for mold growth. The equipment investment is large and it is not easy to maintain the humidity in the constant temperature space. After the experiment is carried out a certain number of times, the mold can easily contaminate the entire constant temperature space, which is difficult to clean and will also affect the subsequent mold test. Therefore, it is necessary to design a mildew resistance testing device and method that can solve the above problems.

[0041] Reference Figure 1 , shows a shoe mildew-proof testing device provided by the present application, the mildew-proof testing device comprising: a box body, a transparent box cover and a solution box detachably connected to the box body; wherein the box body is provided with a containing space for containing the product to be tested;

[0042] The transparent box cover is movably connected to the box body, and the inner surface of the transparent box cover is covered with a polyester film;

[0043] The connection surface between the box body and the solution box is provided with a channel for communicating the box body and the solution box; wherein, the connection between the box body and the transparent box cover, and the connection between the box body and the solution box are both provided with a colloid for sealing.

[0044] In the embodiments of the present application, compared with the problems of unstable internal humidity, large equipment investment, difficult operation and inconvenient cleaning in the prior art, the present application provides an anti-mildew testing device with an independent and sealed test space and a simple structure, specifically: "The anti-mildew testing device comprises: a box body, a transparent box cover and a solution box detachably connected to the box body; wherein, a accommodating space for accommodating the product to be tested is provided in the box body; the transparent box cover is movably connected to the box body, and the inner surface of the transparent box cover is covered with a polyester film; the connecting surface between the box body and the solution box is provided with a channel for connecting the box body and the solution box; wherein, the connection between the box body and the transparent box cover, and the connection between the box body and the solution box are both provided with a colloid for sealing", by placing the product to be tested in the box body, an independent space is provided for the anti-mildew test of the shoes, thereby achieving the technical effect of reducing equipment investment and facilitating operation; and the internal mold only grows in the device, thereby achieving the technical effect of convenient cleaning; and by providing a sealing colloid, the technical effect of maintaining the internal humidity of the device stable is achieved.

[0045] Next, a shoe mildew proof testing device in this exemplary embodiment will be further described.

[0046] The anti-mildew testing device comprises: a box body, a transparent box cover and a solution box detachably connected to the box body; wherein the box body is provided with a containing space for containing the product to be tested;

[0047] The transparent box cover is movably connected to the box body, and the inner surface of the transparent box cover is covered with a polyester film;

[0049] It should be noted that the box body of the present application is based on being able to hold a whole shoe, and is small in size, easy to operate and clean; and is provided with a colloid for sealing, which can prevent the liquid in the solution box from volatilizing, and can also prevent the internal mold from floating out and polluting the experimental environment. The experimenter can observe the mold growth of the product to be tested inside the box body through the transparent box cover. The transparent box cover adopts a curved dome-style design, and the inner surface is attached with a polyester film, which can effectively prevent the formation of liquid dripping on the inner surface of the transparent box cover, thereby affecting the mold growth on the sample surface. A channel or a hollow mesh plate is provided between the solution box and the box body, and the saturated salt solution inside the solution box can evaporate into the box body through the channel to maintain the humidity inside the box body and meet the growth conditions of mold.

[0050] In addition, the box body, the box cover and the solution box are all made of high-strength plastic that is resistant to salt solutions, so as to prevent the mildew-proof test device from being corroded by saturated salt solutions and extend the service life of the mildew-proof test device.

[0051] In a specific implementation, if Figure 2 As shown, the solution box can also be divided into a plurality of separate solution boxes. When a plurality of saturated salt solutions are needed, different salt solutions can be placed in different solution boxes respectively to prevent different saturated salt solutions from mixing with each other.

[0052] In an embodiment of the present application, a drawer sleeve is provided at the bottom of the box body, and the solution box is movably arranged in the drawer sleeve; wherein the edges of the solution box are provided with a colloid for sealing.

[0053] It should be noted that the solution box is generally a cube, and the outer surface edge of the solution box is provided with the colloid, and the colloid fills the gap between the solution box and the drawer cover, so that even if the solution box is placed in the drawer cover, it can be guaranteed to be airtight; the solution box is also provided with a handle for pulling out, which is convenient for extracting the solution box.

[0054] In an embodiment of the present application, the solution box is provided with a scale for observing the internal solution level; the box body is provided with an inspection hole for measuring temperature and air tightness, and a detachable sealing cover is provided at the inspection hole.

[0056] As an example, an opening may be provided in the middle of the sealing cover, and a temperature measuring instrument and an air-tightness detection device pass through the opening. The sealing cover fits tightly with the temperature measuring instrument and the air-tightness detection device to further ensure the air-tightness inside the anti-mildew testing device during detection.

[0057] In a specific implementation, the box cover described in the present application is 30 cm long, 20 cm wide, and 10 cm high; the box body is 30 cm long, 20 cm wide, and 15 cm high; the drawer cover is 30 cm long, 20 cm wide, and 5 cm high; the length, width, and height of the solution box are slightly smaller than those of the drawer cover, and the surface of the solution box fits tightly with the colloid and the drawer cover.

[0058] Reference Figure 3 , shows a shoe mildew proof testing method of the present application, using a shoe mildew proof testing device as described above, the method comprises the following steps:

[0059] S110, obtaining a product to be tested, a control sample and a saturated salt solution, determining the type and volume of the mold spore suspension according to the type of the product to be tested, and uniformly spraying the mold spore suspension onto the surfaces of the product to be tested and the control sample to obtain a mold-coated product to be tested and a mold-coated control sample;

[0060] S120, placing the coated test product and the coated control sample into the containing space respectively, placing the saturated salt solution into the solution box, to obtain a test box;

[0061] S130, determining the temperature and test duration of the constant temperature space according to the types of the saturated salt solution and the mold spore suspension, and placing the test box in the constant temperature space until the test duration is reached, to obtain a final product to be tested and a final control sample;

[0062] S140, comparing the final product to be tested with the final control sample, and determining the anti-mildew capability of the product to be tested.

[0063] Next, a shoe mildew proofing test method in this exemplary embodiment will be further described.

[0064] As described in step S110, obtain a product to be tested, a control sample and a saturated salt solution, determine the type and volume of the mold spore suspension according to the type of the product to be tested, and evenly spray the mold spore suspension onto the surface of the product to be tested and the control sample to obtain a mold-coated product to be tested and a mold-coated control sample.

[0065] In an embodiment of the present invention, the specific process of “obtaining the product to be tested” in step S110 may be further explained in combination with the following description.

[0066] As described in the following steps, an initial sample is obtained, and the initial sample is pre-treated by high-pressure sterilization to obtain a product to be tested.

[0067] It should be noted that the product to be tested is a shoe, or other types of products that need to be tested for mildew resistance. The control sample is a test paper. The mold spore suspension can be evenly sprayed on the surface of the product to be tested and the control sample using a nozzle to avoid the formation of large droplets that slide down and cause uneven coverage of the flora. According to the type of the product to be tested, the type of mold that is most likely to contaminate the product to be tested under the use environment is selected as the type of mold spore suspension. For example, the product to be tested of textile materials can select a single Aspergillus mold spore suspension, such as Aspergillus niger or Aspergillus braziliensis; two molds can also be selected, such as Aspergillus and Chaetocystis sphaeroides; the product to be tested of polymer materials can select five types of mold spore suspensions for testing; the types of the mold spore suspension include but are not limited to Aspergillus niger, Aspergillus braziliensis, Chaetocystis sphaeroides, Trichoderma viride, Aureobasidium sphaeroides, Penicillium citrinum, and Paecilomyces variotii; the density of the mold spore suspension is 10 5 Spores / mL~10 6 Spores / mL.

[0068] In addition, in order to prevent the product to be tested from carrying other types of molds or other microorganisms that may affect the experiment, the product to be tested may be selectively subjected to high-pressure sterilization pretreatment before the experiment.

[0069] It should be noted that the saturated salt solution described in the present application includes one of a saturated solution of magnesium chloride, a saturated solution of magnesium nitrate, a saturated solution of potassium iodide, a saturated solution of sodium nitrate, a saturated solution of sodium chloride, a saturated solution of potassium nitrate, and a saturated solution of magnesium nitrate; when each different saturated salt solution is at a different temperature in the mildew resistance test, the humidity in the mildew resistance test device is also different, and the humidity corresponding to different saturated salt solutions at different temperatures is shown in Table 1 below.

[0070]

[0071] Table 1

[0072] As described in step S120, the coated test product and the coated control sample are placed in the containing space respectively, and the saturated salt solution is placed in the solution box to obtain a test box.

[0073] It should be noted that the coated test product and the coated control sample are placed flat in the box body to avoid contact between the two, and then the box cover is closed; the saturated salt solution is placed in the solution box, and the solution box is placed in the drawer cover to finally form the test box.

[0074] As described in step S130, the temperature and test duration of the constant temperature space are determined according to the types of the saturated salt solution and the mold spore suspension, and the test box is placed in the constant temperature space until the test duration is reached to obtain the final product to be tested and the final control sample.

[0075] In one embodiment of the present invention, the specific process of "determining the temperature and test duration of the constant temperature space according to the types of the saturated salt solution and the mold spore suspension, and placing the test box in the constant temperature space until the test duration is reached" in step S130 can be further explained in combination with the following description.

[0076] As described in the following steps, the test box is placed in the constant temperature space, and the sealing, temperature and humidity inside the box body are checked through the inspection hole;

[0077] When the sealing performance of the box body reaches a preset sealing degree, the test box is placed in the constant temperature space until the test time is reached.

[0078] As described in the following steps, the step of placing the test box in the constant temperature space until the test time is reached includes:

[0079] Determining whether the saturated salt solution needs to be supplemented according to the scale;

[0080] The mold growth of the test sample covered with mold is observed through the transparent box cover.

[0081] It should be noted that the temperature and test duration of the constant temperature space are determined according to the humidity and type of saturated salt solution required for the growth of the mold spore suspension to simulate the mold growth process; the test duration is generally selected according to the cycle, such as 7 days, 14 days, 21 days, and so on. After the preset experimental duration, observe the mold growth of the coated test product and the coated control sample; and be ready to replenish the saturated salt solution at any time to ensure that the mold can grow normally, avoid wasting time due to test failure, and avoid sterilization after multiple failed tests to reduce resource consumption.

[0082] As described in step S140, the final product to be tested is compared with the final control sample, and the anti-mildew ability of the product to be tested is determined.

[0083] In an embodiment of the present invention, the specific process of "comparing the final product to be tested with the final control sample and determining the anti-mildew ability of the product to be tested" in step S140 can be further explained in combination with the following description.

[0084] As described in the following steps, the mold growth of the final product to be tested is judged according to the mold growth of the final control sample to obtain comparison data;

[0085] Obtaining a mold sample of the final product to be tested, and observing the mold sample using a microscope to obtain observation data;

[0086] The anti-mildew ability of the product to be tested is determined based on the comparison data and the observation data.

[0087] As described in the following steps, the steps after determining the anti-mildew ability of the product to be tested include:

[0088] The final product to be tested, the final control sample and the anti-mildew test device are sterilized by high pressure.

[0089] It should be noted that the comparison data is a comparison of the mold growth and mold coverage of the product to be tested with the mold growth and mold coverage of the control sample; or it is judged whether the mold growth of the product to be tested exceeds the standard according to the preset mildew prevention standard; and the mold on the surface of the product to be tested is observed under a microscope to judge whether the mold is the mold type in the mold spore suspension used.

[0090] If it is determined that the mold growing on the surface of the product to be tested is the type of mold used in the test, and the mold growth of the product to be tested is better or similar to that of the control sample, then the anti-mold ability of the product to be tested is unqualified; conversely, if the mold growth of the product to be tested is not as good as that of the control sample, then the anti-mold ability of the product to be tested is better.
