A wiping mechanism is provided on the inner side of the sample holder 2. The wiping mechanism consists of a wiping component 21, symmetrically arranged locking components 22, symmetrically arranged movable components 23, and symmetrically arranged adjusting components 24. The wiping component 21 consists of a seat 211 and a sponge block 212, with the sponge block 212 fixed to the bottom end of the seat 211. The movable component 23 consists of a movable slot 231 and a movable block 232. The movable slot 231 is located at both sides of the seat 211, and the movable block 232 is disposed inside the movable slot 231. The adjusting component 24 is disposed on the movable block 232. Between the movable block 232 and the base 211, the engaging component 22 is located at the connection between one end of the movable block 232 and the inner side of the sample holder 2. Through the designed wiping mechanism, the previous method of drying the inside of the sample holder 2 before placing the insulation cotton during the hydrophobicity test is improved. Currently, wiping with a cloth is inconvenient. By setting a wiping mechanism inside the sample holder 2, water stains can be quickly cleaned inside the sample holder 2 after the hydrophobicity test, facilitating subsequent hydrophobicity tests. The top of the movable block 232 is at the same level as the top of the base 211. The adjusting component 24 consists of a movable groove 241, an adjusting rod 242, and an adjusting groove 243. The adjusting groove 243 is located at... At the end of the movable slot 231, when the wiping assembly 21 needs to be disassembled, the adjusting rod 242 is rotated, causing one end of the adjusting rod 242 to rotate inside the movable slot 241 and the other end to rotate inside the adjusting slot 243, causing the movable block 232 to move inside the movable slot 231, thus separating the slider 222 from the slide groove 221 and completing the disassembly operation of the wiping assembly 21. The movable slot 241 is located at the other end of the movable block 232, and the adjusting rod 242 is located inside the movable slot 231. During the wiping process inside the sample holder 2, the seat 211 is pushed, causing the sponge block 212 at the bottom to absorb water stains on the inner wall of the sample holder 2, achieving the effect of wiping and drying the inside of the sample holder 2. The adjusting rod 24... One end of the adjusting rod 242 is engaged with the inner side of the movable groove 241, and the other end of the adjusting rod 242 is engaged with the inner side of the adjusting groove 243 and connected by threads. The engaging assembly 22 consists of a sliding groove 221 and a slider 222. The sliding groove 221 is opened on the inner wall of the sample holder 2, and the slider 222 is set inside the sliding groove 221. The end of the slider 222 is fixed to one end of the movable block 232. During the movement of the wiping assembly 21, the slider 222 slides inside the sliding groove 221. The edge of the end of the slider 222 has an arc-shaped structure. The slider 222 has a cylindrical structure, and the cross-section of the sliding groove 221 has a rectangular structure. A support rod 4 is fixed on the base 1, and a flow meter 3 is installed on the side of the support rod 4. A nozzle 5 is set at the upper end of the sample holder 2 and at the end of the support rod 4.The insulation cotton placed inside the sample holder 2 is sprayed through nozzle 5. Key performance indicators of the insulation cotton, such as thermal conductivity, fire resistance, sound absorption, and compressive strength, directly affect its effectiveness in practical applications. Through testing, these properties can be comprehensively evaluated to ensure that the product achieves the expected heat insulation, heat preservation, and safety effects in actual use.

[0022] In this embodiment, preferably, a fixing component 25 is provided at the connection between the rear side of the seat 211 and the inner side of the sample holder 2. The fixing component 25 consists of a fixing groove 251, a silicone seat 252, and a fixing block 253. The fixing groove 251 is opened on the inner side of the sample holder 2. The fixing block 253 is fixed to the rear side of the seat 211 and is inserted into the inner side of the fixing groove 251. The silicone seat 252 is disposed between the fixing groove 251 and the fixing block 253. The outer side of the silicone seat 252 is fixed to the inner wall of the fixing groove 251. After the wiping component 21 is used up, the fixing component 25 fixes the wiping component 21 by adhering it to the inner side of the sample holder 2 and simultaneously inserting the fixing block 253 into the inner side of the fixing groove 251 and pressing the silicone seat 252.

[0023] The working principle and usage process of this utility model are as follows: During the water repellency test of the thermal insulation cotton, the thermal insulation cotton is placed inside the sample holder 2, and water of a certain flow rate is sprayed onto the sample through the nozzle 5 for a specified time. By measuring the change in the mass of the sample before and after spraying, the volume percentage of the impermeable part in the sample is calculated. After the thermal insulation cotton test is completed, the wiping mechanism is operated to wipe away the water inside the sample holder 2 for the next test.
