Description

Technical Field

[0001] This invention belongs to the field of anti-mite performance testing technology, specifically relating to an anti-mite testing device for simulating the usage environment of down jackets. Background Technology

[0002] Down jackets help people protect themselves from the cold and are a mainstream warm clothing choice for autumn and winter. Down is made of animal fibers rich in fat and protein and has good moisture absorption. Mites feed on fat and protein and thrive in dark, damp environments, making down jackets prone to mite infestation. When people are bitten by mites, symptoms such as dermatitis, hives, or pruritus may appear on the skin. Mite excrement and corpses are also strong allergens. If mites enter the respiratory or digestive system, they can easily cause lung mite infestations and intestinal mite infestations that are difficult to cure. Therefore, in various tests of down jackets, mite-proofing tests play a crucial role in protecting human health.

[0003] Chinese patent document CN201910734284.X discloses a testing device for the mite-proof performance of anti-mite household textiles. The device includes a testing platform and symmetrically arranged placement slots on the upper surface of the testing platform. During testing, the sample to be tested and a control sample are placed in the left and right placement slots respectively. A clamping mechanism is provided on the testing platform. After the sample to be tested and the control sample are placed, the clamping mechanism clamps and fixes them in place. This testing device can simulate a daily use environment. After the sample to be tested and the control sample are placed on the testing device for a period of time, the device can automatically test the fabric, thereby improving testing efficiency. However, during the testing process, the device failed to isolate the test sample and the control sample, making the two sets of experiments prone to interference. The device uses a water pump to spray the solution in the storage chamber onto the test sample and the control sample through nozzles. The solution used to simulate human sweat and oil is also sprayed onto the test platform around the placement tank, expanding the unnecessary activity area of ​​mites and easily introducing detection errors. During the process of capturing mites, the device uses a motor in conjunction with a vacuum cleaner to suck up the mites. When this device is applied to the mite-proof test of down jackets, some mites hide inside the down jacket and are difficult to be sucked into the test chamber by the vacuum cleaner. The test results cannot accurately reflect the mite-proof performance of the down jacket. There is still room for improvement in the control of the mite activity area and the mite capture method in the existing technology, and the evidentiary value of the mite-proof test needs to be strengthened. Summary of the Invention

[0004] The purpose of this invention is to provide a mite-proof testing device for simulating the usage environment of down jackets in order to solve the above-mentioned problems, which can optimize the mite activity area and mite capture method.

[0005] The present invention achieves the above objectives through the following technical solutions:

[0006] An anti - mite test device for simulating the usage environment of a down jacket, comprising a test bench and two positioning components symmetrically arranged on the top wall of the test bench. A围挡组件 (enclosure component) is fixedly arranged on the top wall of the test bench to surround the positioning components. The enclosure component includes an enclosure wall with gaps opened at both ends of the bottom, a heat - conducting layer arranged at the top of the enclosure wall, a partition plate embedded between the two positioning components, a bottom door arranged at the gap of the enclosure wall, and a lifting device for driving the partition plate. A heating component is arranged at the top of the partition plate. A cooling component and a spraying component are arranged on the test bench. The spraying component is used to spray a liquid simulating human sweat and grease onto the positioning components. The enclosure component cooperates with the heating component and the cooling component to limit the activity range of mites on the positioning components. A capture box corresponding to the gap is also arranged on the test bench. During the test, the heat - conducting layer of the enclosure component is heated by the heating component, so that a figure - eight - shaped heat - energy isolation zone is formed at the top of the enclosure component to limit the activity range of mites. At the same time, the cooling component keeps the environmental temperature around the sample at a temperature suitable for the survival of mites. The spraying component intermittently sprays the liquid simulating human sweat and grease onto the test sample and the control sample. After a period of time, the mites in the test sample and the control sample are collected. The bottom door is opened and the cooling component is closed. The partition plate is driven to move down by the lifting device, so that the heat of the heating component is transferred from the middle position inside the enclosure wall to the gaps on both sides. Driven by the habit of preferring dark environments and heat, the mites drill down into the capture box from the gaps

[0007] As a further optimized solution of the present invention, limit covers corresponding to the gaps of the enclosure wall are fixedly arranged at the bottom of both ends of the enclosure wall. The bottom end of the limit cover is closely attached to the top wall of the test bench. Trapping grooves corresponding to the gaps are opened on the top wall of the test bench. One end of the bottom door close to the partition plate is closely attached to one end of the trapping groove close to the partition plate. A guiding channel communicating with the capture box is formed between the other end of the bottom door far from the partition plate and the trapping groove. After the bottom door is opened, mites can enter the guiding channel between the trapping groove H and the bottom door through the gap. Under the action of heat and light, the mites crawl down along the guiding channel into the capture box. The limit cover plays a role in blocking light and intercepting mites, thus further optimizing the driving direction of mites

[0008] As a further optimized solution of the present invention, the heating component includes a heat - conducting shell fixedly arranged at the top of the partition plate and fitted with the heat - conducting layer, a heating device installed inside the heat - conducting shell, and a first temperature sensor arranged outside the heat - conducting shell. The first temperature sensor is electrically connected to the heating device. The heat - conducting shell and the heat - conducting layer form a figure - eight - shaped heat - energy isolation zone. The heating device cooperates with the first temperature sensor to keep the heat - energy isolation zone within a relatively high temperature range value

[0009] As a further optimization of the present invention, the heating component further includes heat-conducting strips fixedly disposed at both ends of the top of the heat-conducting shell. An insulation shell is slidably connected to the outside of the heat-conducting strips. The insulation shell is fixedly disposed at the top of the heat-conducting layer. The insulation shell as a whole, as well as the top of the enclosure wall and partition, are all made of heat-insulating material. After the heating component descends to fit with the positioning component, the heat-conducting strips can still fit with the heat-conducting layer. The heating device continuously inputs heat into the heat-conducting layer through the heat-conducting shell and the heat-conducting strips, preventing mites from escaping upwards from the enclosure component. The insulation shell insulates the heat-conducting strips, reducing energy waste when heat-conducting strips are installed.

[0010] As a further optimization of the present invention, the lifting device is a lead screw motor. The bottom end of the partition is fixed with a nut assembly threadedly connected to the output end of the lead screw motor. The lead screw motor is fixedly mounted on the bottom wall of the test bench. The partition has a through hole corresponding to the output end of the lead screw motor. The top wall of the test bench has a through groove corresponding to the partition. The two bottom doors are connected by a U-shaped frame. The U-shaped frame is spring-loaded to the test bench. The lead screw motor passes through the U-shaped frame. While driving the partition to descend, the lead screw motor also drives the U-shaped frame and bottom doors to descend through the partition. During the collection of mites, the lead screw motor, in conjunction with the nut assembly, drives the partition to descend. After the partition abuts against the U-shaped frame, it continues to move downward. When the heating component is flush with the positioning component, the partition opens the bottom door downward through the U-shaped frame.

[0011] As a further optimization of the present invention, the cooling assembly includes a first water pump fixedly mounted on the top wall of the test platform, a water tank connected to the inlet of the first water pump, a branch pipe connected to the outlet of the first water pump, a manifold fixedly mounted on the rear end of the enclosure wall, a heat-absorbing pipe connected to the outlet of the branch pipe and the inlet of the manifold pipe, a heat-conducting pipe fixedly mounted on the outlet of the manifold pipe, and a second temperature sensor mounted on the lower part of the enclosure wall. The second temperature sensor is electrically connected to the first water pump. The heat-absorbing pipe is in close contact with the enclosure wall. The end of the heat-conducting pipe away from the manifold pipe is connected to the water tank. When the second temperature sensor detects that the temperature at the lower part of the enclosure wall exceeds the cooling threshold, the first water pump starts and pumps the cooling water in the water tank from the branch pipe to the heat-absorbing pipe. After absorbing the heat from the enclosure wall, the cooling water returns to the water tank through the manifold pipe and the heat-conducting pipe.

[0012] As a further optimization of the present invention, the positioning component includes a positioning plate fixedly disposed on the top wall of the test platform, and two torsion springs and two positioning frames symmetrically arranged on the positioning plate. One end of the torsion spring is fixed to the top of the positioning plate, and the other end of the torsion spring is fixed to the positioning frame. Both positioning plates are embedded with heat-conducting components. One end of the heat-conducting component is located at the center of the positioning plate, and the other end of the heat-conducting component extends towards the partition. After the heat-conducting layer descends, it can fit into the positioning plate and the heat-conducting component on the positioning plate. During the collection of mites, the heating component quickly transfers heat to the center of the positioning plate through the heat-conducting component, causing the mites in the test sample and the control sample to quickly leave their respective inhabiting samples.

[0013] As a further optimization of the present invention, the spray assembly includes a support frame fixedly mounted on the top wall of the test bench, a second water pump fixedly mounted on the top of the support frame, a liquid storage tank connected to the inlet of the second water pump, a liquid distributor connected to the outlet of the second water pump, a first diffusion nozzle connected to the liquid distributor via a spray pipe, and a lifting mechanism fixedly mounted on the top wall of the support frame. The output end of the lifting mechanism is fixedly connected to the liquid distributor. The liquid storage tank is used to store liquids simulating human sweat and oil. The first diffusion nozzles are divided into two groups, and the two groups of first diffusion nozzles correspond to two positioning components. The top of the liquid distributor is fixed with a guide rod that penetrates the top wall of the support frame. During the intermittent spraying of the sample by the spraying assembly, the liquid distributor is lowered by the lifting mechanism. Then, the second water pump pumps the liquid simulating human sweat and oil from the storage tank into the liquid distributor. After passing through the spray pipe, the liquid is sprayed from the first diffusion nozzle onto the test sample and the control sample. The lifting mechanism resets the liquid distributor to complete one spraying cycle. By spraying the sample at close range, liquid waste is reduced, and the liquid simulating human sweat and oil is prevented from adhering to areas outside the sample, further limiting the living space of mites.

[0014] As a further optimized solution of the present invention, the mite-proof testing device further includes a dosing component and an inspection component corresponding to the capture box one by one. The dosing component includes a third water pump arranged on the bottom wall of the test bench, a solution tank communicated with the water inlet of the third water pump, a liquid distribution pipe communicated with the water outlet of the third water pump, and a second diffusion nozzle fixed at the outlet of the liquid distribution pipe. The second diffusion nozzle penetrates through the capture box. The solution tank is used to store the mite detection liquid. The inspection component includes a mounting rack arranged on the top wall of the test bench, a telescopic device fixed on the top wall of the mounting rack, a box body fixed at the output end of the telescopic device, and a test paper arranged inside the box body. The lower part of the box body is open and penetrates through the capture box. A limiting hole corresponding to the box body is opened on the top wall of the test bench. After the collection of mites is completed, the mite detection liquid in the solution tank is injected into the liquid distribution pipe by the third water pump. The detection liquid in the liquid distribution pipe is sprayed into the capture box in a large range in a misty state through the second diffusion nozzle, quickly covering the inner surface of the capture box with a layer of liquid, avoiding the phenomenon of mite escape during the spraying of the detection liquid. After the detection liquid soaks the mites for a period of time, the box body together with the test paper is pushed into the detection liquid in the capture box by the telescopic device, and the number of mites is detected by the test paper.

[0015] As a further optimized solution of the present invention, a plurality of insect repellent lamps are installed at the front and rear ends inside the enclosure wall. The light intensity of the plurality of insect repellent lamps gradually decreases from the partition board to both ends in the length direction of the enclosure wall. The insect repellent lamps are arranged by utilizing the light avoidance characteristic of mites, so that the light intensity inside the enclosure wall gradually decreases from the middle to both sides. During the process of collecting mites, it promotes the mites to move towards the gap of the enclosure wall.

[0016] The beneficial effects of the present invention are as follows:

[0017] 1) The present invention heats the heat conduction layer of the enclosure component through the heating component, forming a day-shaped heat energy isolation zone at the top of the enclosure component. At the same time, the cooling component keeps the ambient temperature around the sample at a temperature suitable for the survival of mites. During the process of collecting mites, the bottom door is opened and the cooling component is closed. The partition board and the heating component are lowered by the lifting device, so that the temperature on the positioning component gradually decreases from the partition board to the direction of the gap of the enclosure wall, driving the mites towards the gap of the enclosure wall. Under the influence of the habit of liking dark environments and the driving effect of heat, the mites drill down into the capture box from the gap, achieving the omission-free collection of mites, controlling the activity range and driving path of mites, reducing experimental interference factors, and improving the probative force of test results;

[0018] 2) During the process of collecting mites, the heat-conducting strip can still adhere to the heat-conducting layer. The heating device continuously inputs heat into the heat-conducting layer through the heat-conducting shell and the heat-conducting strip, preventing mites from escaping upwards from the enclosure component. The heat-conducting strip is insulated by the heat-insulating shell, reducing energy waste when the heat-conducting strip is set. The heating component quickly transfers heat to the center of the positioning plate through the heat-conducting component. Insect-repelling lamps are set up using the light-avoiding characteristics of mites, so that the light intensity inside the enclosure wall gradually decreases from the middle to both sides, improving the efficiency of mite collection.

[0019] 3) The liquid distribution component, thermal isolation belt and cooling component of the spray assembly of the present invention are all symmetrical structures, which can ensure that the nutrient feeding status, the heating effect of the thermal isolation belt and the heat dissipation effect of the heat absorption tube are consistent for the two samples, and avoid interference from irrelevant variables on the mite prevention test.

[0020] 4) After the collection of mites is completed, the present invention uses a third water pump to inject the mite detection solution in the solution tank into the distribution pipe. The detection solution in the distribution pipe is sprayed into the capture box in a mist form through the second diffusion nozzle, quickly covering the inner surface of the capture box with a layer of liquid. This prevents mites from escaping during the spraying of the detection solution, ensures and improves the accuracy of the test results, and provides life safety protection for the personnel involved in the test.

Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0031] Example

[0032] Please see Figure 1 and Figure 2, a mite-proof test device for simulating the usage environment of down jackets, comprising a test bench 1 and two positioning components 2 symmetrically arranged on the top wall of the test bench 1. During the test, the test sample and the control sample are respectively fixed on the two positioning components 2. The same number of mites inhabit the test sample and the control sample. The test sample and the control sample are down jackets of different qualities. A围挡组件 3 for surrounding the positioning components 2 is fixedly arranged on the top wall of the test bench 1. The围挡组件 3 includes a围挡壁 301 with gaps opened at both ends of the bottom, a heat conduction layer 302 arranged at the top of the围挡壁 301, a partition plate 303 embedded between the two positioning components 2, a bottom door 304 arranged at the gap of the围挡壁 301, and a lifting device for driving the partition plate 303. A heating component 4 is arranged at the top of the partition plate 303. The heat conduction layer 302 of the围挡组件 3 is heated through the heating component 4, so as to form a figure-eight-shaped heat energy isolation zone at the top of the围挡组件 3 to limit the activity range of the mites. A cooling component 5 and a spraying component 6 are arranged on the test bench 1. The spraying component 6 is used to spray a liquid simulating human sweat and oil on the positioning components 2. The lower part of the围挡组件 3 is cooled through the cooling component 5, so as to keep the environmental temperature around the test sample and the control sample at a temperature suitable for the survival of mites. The liquid simulating human sweat and oil is intermittently sprayed on the test sample and the control sample through the spraying component 6. The围挡组件 3 cooperates with the heating component 4 and the cooling component 5 to limit the activity range of the mites on the positioning components 2. A capture box 7 corresponding to the gap is also arranged on the test bench​​​​​​, 6. At the bottom ends of both sides of the enclosure wall 301, there are fixed limit covers 305 corresponding to the gaps in the enclosure wall 301. The bottom end of the limit cover 305 is closely attached to the top wall of the test bench 1. On the top wall of the test bench 1, there is a trapping groove H corresponding to the gap. One end of the bottom door 304 close to the partition 303 is closely attached to one end of the trapping groove H close to the partition 303. A guiding channel communicating with the capture box 7 is formed between the other end of the bottom door 304 away from the partition 303 and the trapping groove H. After the bottom door 304 is opened, mites can enter the guiding channel between the trapping groove H and the bottom door 304 through the gap. Under the action of heat and light, the mites crawl down along the guiding channel into the capture box 7. The limit cover 305 plays a role in shading and intercepting mites, thereby further optimizing the driving direction of mites.

[0034] Please refer to Figure 5 , the heating component 4 includes a heat-conducting shell 401 fixedly arranged at the top end of the partition 303 and fitted with the heat-conducting layer 302, a heating device 402 installed inside the heat-conducting shell 401, and a first temperature sensor 403 arranged outside the heat-conducting shell 401. The first temperature sensor 403 is electrically connected to the heating device 402. The heating device 402 is specifically a heating rod. The heat-conducting shell 401 and the heat-conducting layer 302 form a heat energy isolation zone in the shape of a Chinese character 'ri'. By cooperating the heating device 402 with the first temperature sensor 403, the heat energy isolation zone is maintained within a relatively high temperature range value. When the first temperature sensor 403 detects that the temperature of the heating component 4 is lower than the heating threshold, the heating device 402 is started. The heating threshold is preferably 45°C.

[0035] Please refer to Figure 5 , the heating component 4 further includes heat-conducting strips 404 fixedly arranged at both ends of the top of the heat-conducting shell 401. The outside of the heat-conducting strips 404 is slidably connected with a heat-insulating shell 405. The heat-insulating shell 405 is fixedly arranged at the top end of the heat-conducting layer 302. The whole heat-insulating shell 405, as well as the top of the enclosure wall 301 and the partition 303, is made of heat-insulating materials. After the heating component 4 descends to be fitted with the positioning component 2, the heat-conducting strips 404 can still be fitted with the heat-conducting layer 302. The heating device 402 continuously inputs heat into the heat-conducting layer 302 through the heat-conducting shell 401 and the heat-conducting strips 404, preventing mites from escaping upward from the enclosure component 3. The heat-insulating shell 405 insulates the heat-conducting strips 404 to reduce energy waste in the case of setting the heat-conducting strips 404.

[0036] Please refer to Figure 3The lifting device is a lead screw motor 306, but an electric push rod, cylinder, or hydraulic cylinder can also be used to replace it. A nut pair 307, threadedly connected to the output end of the lead screw motor 306, is fixed to the bottom end of the partition 303. The lead screw motor 306 is fixed to the bottom wall of the test bench 1. A through hole corresponding to the output end of the lead screw motor 306 is opened inside the partition 303. A through groove I corresponding to the partition 303 is opened on the top wall of the test bench 1. The two bottom doors 304 are connected by a U-shaped frame 308. 308 is spring-loaded to the test bench 1. The lead screw motor 306 passes through the U-shaped frame 308. While driving the partition 303 to descend, the lead screw motor 306 also drives the U-shaped frame 308 and the bottom door 304 to descend through the partition 303. During the collection of mites, the lead screw motor 306, in conjunction with the nut pair 307, drives the partition 303 to descend. After the partition 303 abuts against the U-shaped frame 308, it continues to move downward. When the heating component 4 is flush with the positioning component 2, the partition 303 opens the bottom door 304 downward through the U-shaped frame 308.

[0037] Please see Figure 6 The cooling assembly 5 includes a first water pump 501 fixedly mounted on the top wall of the test bench 1, a water tank 502 connected to the inlet of the first water pump 501, a branch pipe 503 connected to the outlet of the first water pump 501, a manifold 504 fixedly mounted on the rear end of the enclosure wall 301, a heat-absorbing pipe 505 connected to the outlet of the branch pipe 503 and the inlet of the manifold 504, a heat-conducting pipe 506 fixedly mounted on the outlet of the manifold 504, and a second temperature sensor 507 mounted on the lower part of the enclosure wall 301. The second temperature sensor 507 is electrically connected to the first water pump 501. The heat-absorbing pipe 505 is in close contact with the enclosure wall 301. The end of the heat-conducting pipe 506 away from the manifold 504 is connected to the water tank 502. When the second temperature sensor 507 is mounted on the lower part of the enclosure wall 301, the second temperature sensor 507 is connected to the water tank 502. When sensor 507 detects that the temperature at the lower part of the enclosure wall 301 exceeds the cooling threshold, the first water pump 501 starts, drawing cooling water from the water tank 502 through the branch pipe 503 to the heat absorption pipe 505. After absorbing the heat from the enclosure wall 301, the cooling water returns to the water tank 502 through the manifold 504 and the heat conduction pipe 506. The cooling threshold is preferably 25°C. A cold head can be added to the heat conduction pipe 506. When the cold head is set, the heat conduction pipe 506 consists of two sections of guide pipes, which are connected to the inlet and outlet of the cold head, respectively. A cooling fan electrically connected to the second temperature sensor 507 can also be added at the location of the cold head. The cooling fan adjusts the airflow according to the temperature information measured by the second temperature sensor 507.

[0038] Please see Figure 8The positioning component 2 includes a positioning plate 201 fixedly mounted on the top wall of the test bench 1, two torsion springs 202 and two positioning frames 203 symmetrically arranged on the positioning plate 201. One end of the torsion spring 202 is fixed to the top of the positioning plate 201, and the other end of the torsion spring 202 is fixed to the positioning frame 203. When fixing the sample, the two positioning frames 203 are pried open, and the two sides of the down jacket sample are respectively inserted into the gaps between the two positioning frames 203 and the positioning plate 201. The positioning frames 203 are then released, and under the action of the torsion springs 202, the positioning frames 203 fix the down jacket sample to the top wall of the test bench 1. The samples are fixed, and heat-conducting components 204 are embedded in both positioning plates 201. One end of the heat-conducting component 204 is located at the center of the positioning plate 201, and the other end of the heat-conducting component 204 extends toward the partition plate 303. After the heat-conducting layer 302 descends, it can fit with the positioning plate 201 and the heat-conducting component 204 on the positioning plate 201. During the process of collecting mites, the heating component 4 quickly transfers heat to the center of the positioning plate 201 through the heat-conducting component 204, causing the mites in the test sample and the control sample to quickly leave their respective inhabited samples.

[0039] Please see Figure 7 The spray assembly 6 includes a support frame 601 fixedly mounted on the top wall of the test bench 1, a second water pump 602 fixedly mounted on the top of the support frame 601, a liquid storage tank 603 connected to the inlet of the second water pump 602, a liquid distributor 604 connected to the outlet of the second water pump 602, a first diffusion nozzle 605 connected to the liquid distributor 604 via a spray pipe, and a lifting mechanism 606 fixedly mounted on the top wall of the support frame 601. The output end of the lifting mechanism 606 is fixedly connected to the liquid distributor 604. The lifting mechanism 606 is an electric push rod, a cylinder, or a hydraulic cylinder. The liquid storage tank 603 is used to store liquids simulating human sweat and oil. The first diffusion nozzles 605 are divided into two groups. Corresponding to the two positioning components 2, the top of the liquid distributor 604 is fixed with a guide rod that penetrates the top wall of the support frame 601. During the intermittent spraying of the sample by the spraying component 6, the liquid distributor 604 is lowered by the lifting mechanism 606. Then, the second water pump 602 pumps the liquid simulating human sweat and oil from the storage tank 603 into the liquid distributor 604. After passing through the spray pipe, the liquid is sprayed from the first diffusion nozzle 605 onto the test sample and the control sample. The lifting mechanism 606 resets the liquid distributor 604 to complete one spraying cycle. By spraying the sample at close range, liquid waste is reduced, and the liquid simulating human sweat and oil is prevented from adhering to areas outside the sample, further limiting the living space of mites.

[0040] Please see Figure 3The mite-proof testing equipment also includes a dosing component 8 and a testing component 9, each corresponding to a capture box 7. The dosing component 8 includes a third water pump 801 mounted on the bottom wall of the test platform 1, a solution tank 802 connected to the inlet of the third water pump 801, a distribution pipe 803 connected to the outlet of the third water pump 801, and a second diffusion nozzle 804 fixedly mounted at the outlet of the distribution pipe 803. The second diffusion nozzle 804 penetrates the capture box 7. The solution tank 802 stores the mite detection solution. The testing component 9 includes a mounting bracket 901 mounted on the top wall of the test platform 1, a telescopic device 902 fixedly mounted on the top wall of the mounting bracket 901, a box 903 fixedly mounted at the output end of the telescopic device 902, and test strips 904 disposed inside the box 903. The telescopic device 902 is an electric push rod, a cylinder, or a hydraulic cylinder. The box 903 has an opening at the bottom that penetrates the capture box 7. The top wall of the container has a limiting hole J corresponding to the box 903. After the mites are collected, the mite detection solution in the solution tank 802 is injected into the distribution pipe 803 by the third water pump 801. The detection solution in the distribution pipe 803 is sprayed into the capture box 7 in a mist form after passing through the second diffusion nozzle 804, quickly covering the inner surface of the capture box 7 with a layer of liquid to prevent mites from escaping during the spraying of the detection solution. After the mites have been soaked in the detection solution for a period of time, the box 903 along with the test paper 904 is pushed into the detection solution in the capture box 7 by the telescopic device 902. The number of mites is detected by the test paper 904. The mounting bracket 901 of the inspection component 9 is detachably placed on the top of the test table 1. After the test is completed, the inspection component 9 is lifted and the box 903 is pulled out from the limiting hole J. The mite prevention performance of the down jacket is judged by checking the test paper 904.

[0041] Please see Figure 2 and Figure 3 Multiple insect-repelling lamps 10 are installed at both the front and rear ends of the inner side of the enclosure wall 301. The light intensity of the multiple insect-repelling lamps 10 gradually decreases from the partition 303 to both ends of the enclosure wall 301 along its length. The insect-repelling lamps 10 are set up by taking advantage of the light-avoiding characteristics of mites, so that the light intensity inside the enclosure wall 301 gradually decreases from the middle to both sides. During the process of collecting mites, the mites are prompted to move towards the opening of the enclosure wall 301.
