[0024] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0025] my country's national standard GB / T24253-2009 covers the evaluation of the mite-proof performance of textiles, including a test using the repellency method. The steps of this test are as follows:

[0026] 1. Place a 10mm thick sponge with a side length of about 200mm in a covered container, and pour in an appropriate amount of saturated salt water (the water level should just submerge the sponge).

[0027] 2. Take 7 petri dishes. Place one petri dish in the center of the adhesive plate as the center petri dish. Arrange the remaining 6 petri dishes evenly around the center petri dish in a petal shape, and use transparent tape of the same width to secure the edges between each petri dish (to act as a bridge). Then fix the 7 petri dishes to the adhesive plate.

[0028] 3. Place the sample and control sample in the six petri dishes at intervals. Spread the sample evenly, flatly and tightly on the bottom of the petri dish, and place 0.05g of mite feed in the center of the sample.

[0029] 4. Place (2000±200) surviving mites on the center petri dish.

[0030] 5. Place the sticky plate assembly containing the test mites and feed on a sponge, cover it with the top cover of the container box, and place it in a constant temperature and humidity incubator at a temperature of (25±2)℃ and a relative humidity of (75±5)%.

[0031] 6. After 24 hours of incubation, observe with a dissecting microscope or stereomicroscope and count the number of surviving adult and nymphal mites in the sample culture dish and the control culture dish using appropriate methods.

[0032] In this experiment, the experimenters needed to fix 7 petri dishes on a sticky plate, and the 7 petri dishes needed to be placed on the surface of the sticky plate in a specific arrangement.

[0033] Example 1

[0034] like Figure 1 and Figure 2As shown, the mite-proof test box of this embodiment 1 includes a base plate 1 and a baffle 2. The upper surface of the base plate 1 is provided with a recess 101. The baffle 2 includes a first baffle tube 201 and six second baffle tubes 202 disposed around the first baffle tube 201. The second baffle tubes 202 are arranged parallel to the first baffle tubes 201, and the second baffle tubes 202 abut against and are fixedly connected to the first baffle tubes 201. Adjacent second baffle tubes 202 abut against each other and are fixedly connected. The lower openings of the first baffle tubes 201 and the second baffle tubes 202 are both snapped into the recess 101. After the baffle 2 is snapped onto the base plate 1, the baffle 2 and the base plate 1 constitute a first assembly. The assembly of the petri dish and the adhesive plate in step 2 of the repellency test involved in the Chinese national standard GB / T 24253-2009 is the second assembly. The first assembly and the second assembly have the same structure. The operation of the first assembly consisting of the enclosure 2 and the base plate 1 is more convenient and helps to reduce the workload of the test personnel. Furthermore, in order to avoid the gap between the enclosure 2 and the base plate 1 from affecting mites (such as mites having difficulty crawling out after entering the gap, and the size of mites is generally 100~500μm), an annular sealing ring is provided between the enclosure 2 and the recessed part 101.

[0035] The mite-proof test chamber also includes a side wall 3 and a top cover 4. The side wall 3 and the bottom plate 1 are integrally connected, and the bottom plate 1, side wall 3, and top cover 4 enclose a test space. The enclosure 2 is located within the test space. A saline tank 102 is provided on the upper surface of the bottom plate 1, surrounding the recess 101. The saline tank 102 is located between the recess 101 and the side wall 3. A fresh water tank 103 is also provided on the upper surface of the bottom plate 1, located between the saline tank 102 and the side wall 3. A water inlet channel is provided between the side of the bottom plate 1 and the side wall of the saline tank 102, and the water inlet channel is equipped with a water inlet plug 5.

[0036] In step 1 of the test for the anti-mite performance of textiles using the repellency method, a sponge is needed to prevent mites from escaping out of the container during the test (to prevent mites from escaping through the gaps between the container lid and the container). If a saline bath 102 is provided on the upper surface of the base plate 1, then a sponge is unnecessary; simply injecting saturated saline solution into the saline bath 102 is sufficient to prevent mites from escaping, reducing the consumption of sponges during the test and the operator's cleaning of the sponges.

[0037] A water inlet channel is provided between the side of the base plate 1 and the side wall of the saline tank 102. The test personnel first place the mite-proof test box into the incubator, and then inject saturated saline into the saline tank 102 to avoid the problem of saline spilling out of the saline tank 102 during the displacement of the mite-proof test box.

[0038] A freshwater tank 103 is provided on the upper surface of the base plate 1, and the freshwater tank 103 is located between the saline tank 102 and the side wall 3. The evaporation of freshwater in the freshwater tank 103 will increase the air humidity inside the mite-proof test box.

[0039] The side wall 3 and the base plate 1 are integrally connected, and the height of the side wall 3 is greater than the height of the enclosure component; therefore, the side wall 3 always has the effect of reducing airflow around the enclosure component 2; when mites are placed in the first enclosure tube 201 without closing the top cover, the side wall 3 reduces the chance of the mites being blown away. Salt water and fresh water can be injected into the corresponding tanks using a syringe.

[0040] Instructions for using this mite-proof test kit:

[0041] 1. Assemble the base plate 1 and the enclosure component 2, and use transparent tape of the same width to stick between the upper opening of the second enclosure pipe 202 and the first enclosure pipe 201, and between the upper openings of adjacent second enclosure pipes 202 (to act as a bridge).

[0042] 2. Place the sample and control sample at intervals inside the six outer second enclosure tubes 202. Spread the sample evenly, flatly and tightly at the bottom of the second enclosure tubes 202, and place 0.05g of mite feed in the center of the sample;

[0043] 3. Place (2000±200) surviving mites at the bottom of the first enclosure pipe 201;

[0044] 4. After filling the fresh water tank with fresh water and covering it with the top cover 4, place the mite prevention test box in a constant temperature and humidity incubator with a temperature of (25±2)℃ and a relative humidity of (75±5)%. Then, inject the saline solution into the saline solution tank 102 through the water injection channel and cover it with the water injection port plug 5.

[0045] 5. After 24 hours of incubation, observe with a dissecting microscope or stereomicroscope and count the number of surviving adult mites and nymphs in the second enclosure tube 202 of the sample and the second enclosure tube 202 of the control sample using appropriate methods.

[0046] Example 2

[0047] like Figure 3 and Figure 4 As shown, the mite-proof test box of Example 2 is based on Example 1, except that it also includes a back plate 7, a controller, a power supply, a heating element 6, and a humidity sensor 8. The back plate 7 is detachably connected to the bottom plate 1, and the upper surface of the back plate 7 is connected to the lower surface of the bottom plate 1. A heating groove 104 is formed on the lower surface of the bottom plate 1. The heating element 6 protrudes from the upper surface of the back plate 7 and is in concave-convex fit with the heating groove 104. The heating element 6 is located below the freshwater tank 103.

[0048] A humidity sensor 8 is installed through the top cover 4, and the probe of the humidity sensor 8 is located within the test space. The controller, power supply, heating element 6, and humidity sensor 8 are electrically connected, and the controller, power supply, and heating element 6 are fixedly mounted on the back plate 7. A flow-blocking groove 105 is also provided on the upper surface of the bottom plate 1, surrounding the recess 101 and located between the recess 101 and the brine tank 102. The bottom surface of the freshwater tank 103 is higher than the bottom surface of the brine tank 102.

[0049] Specifically, the humidity sensor 8 is used to monitor the humidity in the test space and transmit the humidity data to the controller. When the humidity in the test space is lower than the preset value, the controller controls the heating element 6 to work. The heating element 6 is used to heat the fresh water in the fresh water tank 103. After being heated, the fresh water in the fresh water tank 103 evaporates faster, and the humidity in the test space rises. When the humidity in the test space reaches the preset value, the controller controls the heating element 6 to stop working, and the humidity in the test space basically stops rising.

[0050] The bottom surface of the freshwater tank 103 is higher than the bottom surface of the brine tank 102. When the heat released by the heating element 6 is working, it is blocked by the brine tank 102 when it is transferred to the enclosure 2. The amount of water evaporation in the brine tank 102 also increases to a certain extent, but the heat is difficult to be further transferred to the enclosure 2 (the maximum working temperature of the heating element 6 is generally 50℃), thus eliminating the influence of the heating element on the mite test results.

[0051] By controlling the temperature within the test space, this mite-proof test box is suitable for constant temperature incubators without humidity control functions. When it is necessary to study the mite-proof effect of textile samples under different humidity conditions, multiple mite-proof test boxes with different preset humidity values ​​can be placed in the same constant temperature incubator to meet the test requirements.

[0052] The flow-blocking groove 105 is located between the recess 101 and the brine tank 102. When the brine in the brine tank 102 is shaken out and flows to the recess 101 during the test, it will be collected by the flow-blocking groove 105.

[0053] Example 3

[0054] like Figure 5 As shown, the mite-proof test box of Example 3 is based on Example 1, except that the abutment of the adjacent second enclosure tube 202 and the abutment of the first enclosure tube 201 and the second enclosure tube 202 are integrally connected; the outer tube walls of the adjacent second enclosure tube 202 and the first enclosure tube 201 and the second enclosure tube 202 are smoothly transitioned.

[0055] Specifically, the upper end faces of the integrally connected second enclosure tube 202 do not require additional transparent tape to provide a flat surface (of predetermined width) for mites to move through, effectively reducing the preparation time for a single mite prevention test. The smooth transition of the outer walls of adjacent second enclosure tubes 202, first enclosure tubes 201, and second enclosure tubes 202 reduces cleaning dead zones, improving cleaning efficiency. Both of these factors contribute to improving the efficiency of batch mite prevention tests.

[0056] Figure 5 The diagram only shows the integral connection structure of two second enclosure tubes 202. Furthermore, six second enclosure tubes 202 are integrally connected with one first enclosure tube 201.

[0057] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
