[0002] The split down jacket consists of two parts, an inner liner and an outer cover, which can be worn independently or combined. According to the weather changes, the combination of the inner liner and the outer jacket can be flexibly selected. There are mainly two methods for testing down jackets, laboratory testing methods and actual environment simulation tests. The actual environment simulation test is more intuitive and will not damage the down jacket.

[0003] The patent with the application number CN202010241073.5 mentions "a testing device and method for the heat preservation performance of finished clothing". This device can simulate different environments, conduct multiple tests on finished clothing, obtain more comprehensive test data, and effectively reduce the cost of testing without a large amount of manual data calculation.

[0014] According to the above technical solution, a heat preservation testing method, according to the testing method of a heat preservation testing system of a split anti-drilling down jacket, includes the following steps: S1: Wear the clothes, open the movable sealing plate, sleeved an ordinary underwear on the outside of the mannequin composed of the model shells, and then wear the inner liner and the outer coat of the down jacket on the outside of the mannequin in sequence. S2: Adjust the body shape. Start the electric push rod to push the heat conducting plate to squeeze the model shell. Then start the air inflation pump. Air enters the closed box body composed of the rubber deformation frame and the heat conducting plate. As the air pressure continuously rises, the rubber deformation frame is squeezed and deformed, and the model shell is further pushed to move through the rubber connecting plate, and the distance between the model shells expands, and the model fits the inner side of the down jacket. S3: State simulation. Intermittently start the air inflation pump and the resistance wire to send in heated air.

S4: Environmental simulation. The circulating air pump extracts the internal air through the circulation holes and sprays it out from the strip-shaped air outlet pipe. The water supply pump extracts clear water through the water inlet holes, and the spray nozzles spray it out to wet the outer side of the down jacket. Then, start the drive motor to drive the drive pipe inside the sealed sleeve to rotate. The drive pipe drives the entire model to rotate slowly, and adjust the angles of the blowing and spraying to the outer side of the down jacket. S5: Data recording. After the detection, the inner liner and the outer jacket are separately detected in sequence, and the temperature and time data are recorded.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. An adjustment and detection component is provided. Push the heat conduction plate to squeeze the model shell, and air enters the closed box body composed of the rubber deformation frame and the heat conduction plate. As the air pressure continuously rises, the rubber deformation frame is squeezed and deformed, and continues to push the model shell to move through the rubber connecting plate. The distance between the model shells expands until the outer sides of the model shells are in contact, completing the wearing of the model. The size of the model can be adjusted by the electric push rod and air pressure to adapt to down jackets of different sizes, making the model wear the down jacket more similar to the state of a human body during detection, so as to improve the accuracy of the detection. During the air supply process, connect the power supply of the resistance wire, control the power of the resistance wire, heat the heat conduction strip and the S-shaped copper tube, and then heat the supplied air, so that the air temperature inside the rubber deformation frame is maintained at 37°C. This temperature is detected by the internal temperature sensor, and the heat will also be transferred to the model shell through the heat conduction plate. The body surface temperature is detected by the external temperature sensor. The model shell is made of silicone rubber, and the thermal conductivity coefficient of this material is close to that of the skin, so as to simulate the internal and body surface temperatures, and the detection result is closer to that of a real person. During the detection, pull the handle to close the movable sealing plate, send cold air through the cold air pipe to lower the environmental temperature. Then, start the sealed air pump, and the sealed air pump inflates the sealed airbag. The sealed airbag expands between the sealed pressing plate and the fixed back plate to close the gap at the connection and reduce the interference of the external environment. Detect the heat preservation ability of the down jacket by detecting the temperature on the outer side of the model through the external temperature sensor, and the volume of the model can be changed by repeatedly starting the electric push rod, making the down jacket and the model alternately come into contact and separate. This method is similar to the state of a human body wearing a down jacket during exercise, and thus simulates the state during exercise. Moreover, when a human body exercises, the internal heat production increases, which can be simulated by increasing the power of the resistance wire. At the same time, simulate the increase in internal heat production of the human body and the state of the human body and the down jacket during exercise to simulate the heat preservation effect during exercise, expand the detection range, and further improve the accuracy of the detection.

[0016] 2. A simulation test component is provided. When it is necessary to simulate the environment, start the circulating air pump. The circulating air pump extracts the internal air through the circulation holes. The air enters the air supply pipe after passing from the partition plate on one side of the circulation box to the partition plate on the other side and then sprays out from the strip-shaped air outlet pipe. Open the annular dust-proof cover, pour clear water into the water tank, the water supply pump extracts the clear water into the water supply pipe through the water inlet hole, and then sprays it out from the nozzle to wet the outer side of the down jacket. The size of the water spray is adjusted by adjusting the power of the water supply pump. Moreover, the driving motor can be started, and the gear drives the gear ring to rotate, thereby driving the rotating pipe in the sealing sleeve to rotate. The rotating pipe drives the rubber deformation frame connected to the pressure relief pipe to rotate, thereby driving the entire model to rotate slowly to adjust the angles of the blowing and water spraying to the outer side of the down jacket, and the simulation of the blowing and raining environment has a better effect; In summary, the adjustment and detection component adapts to down jackets of different sizes by changing the volume of the model to improve the detection accuracy, and can simulate the state of the down jacket during movement, making the detection closer to the state of real human wearing, so as to further improve the detection accuracy. The simulation test component simulates the states of blowing and raining. The two are combined with each other, making it closer to the heat preservation state of a real person wearing a down jacket in different environments, and will not cause damage to the human body, with better and more accurate detection effects.

[0022] As Figure 9 shown, a test method for a heat preservation test system of a split-type anti-drilling down jacket includes the following steps: S1: Wear the clothes, open the movable seal plate 217, sleeve an ordinary underwear on the outside of the human model formed by combining the model shells 210, and then wear the inner liner and the outer coat of the down jacket on the outside of the human model in sequence; S2: Adjust the body shape, start the electric push rod 207 to push the heat conduction plate 206 to squeeze the model shell 210, then start the air pump 230. Air enters the closed box body formed by the rubber deformation frame 203 and the heat conduction plate 206. As the air pressure continuously rises, the rubber deformation frame 203 is squeezed and deformed, and continues to push the model shell 210 to move through the rubber connecting plate 209. The distance between the model shells 210 expands, and the model fits the inner side of the down jacket; S3: State simulation, intermittently start the air pump 230 and the resistance wire 228 to send in heated air. By reciprocally starting the electric push rod 207, change the volume of the model, so that the down jacket and the model alternately come into contact and separate, simulating the state during exercise. Simulate by increasing the power of the resistance wire 228. At the same time, simulate the heat generation inside the human body increasing and the state of the human body and the down jacket during exercise to simulate the heat preservation effect during exercise; S4: Environment simulation, the circulating air pump 307 extracts the internal air through the circulation holes 303 and sprays it out from the strip-shaped air outlet pipe 305. The water supply pump 311 extracts clear water through the water inlet holes 310, and the spray head 313 sprays it out to wet the outer side of the down jacket. Start the drive motor 319 to drive the drive pipe 315 inside the sealed sleeve 316 to rotate. The drive pipe 315 drives the entire model to rotate slowly, and adjusts the angles of the blowing and spraying to the outer side of the down jacket; S5: Data recording, after detection, then separately detect the inner liner and the outer jacket in sequence, and record the data of temperature and time.

[0023] The working principle and usage process of the present invention: Pull the handle 218 to open the movable sealing plate 217, sleeved an ordinary underwear on the outside of the human body model formed by the model shells 210. Then wear the inner liner and the outer jacket of the down jacket on the outside of the human body model in sequence. Start the electric push rod 207 to push the heat conduction plate 206 to squeeze the model shell 210. Then start the air pump 230. Air enters the closed box body formed by the rubber deformation frame 203 and the heat conduction plate 206 through the S-shaped copper pipe 227 and the air supply inner pipe 225. As the air pressure continuously rises, the rubber deformation frame 203 is squeezed and deformed, and continues to push the model shell 210 to move through the rubber connecting plate 209. When the air is being sent in, connect the power supply of the resistance wire 228, control the power of the resistance wire 228, heat the heat conduction strip 229 and the S-shaped copper pipe 227, and then heat the incoming air, so that the air temperature inside the rubber deformation frame 203 is maintained at 37 °C. This temperature is detected by the internal temperature sensor 208, and the heat will also be transferred to the model shell 210 through the heat conduction plate 206. The body surface temperature is detected by the external temperature sensor 224. The model shell 210 is made of silicone rubber, and the thermal conductivity coefficient of this material is close to that of the skin, so as to simulate the temperature inside and on the body surface, and the detection result is closer to the detection of real people; During the process of adjusting the size of the above-mentioned adjustment model shell 210, the middle plate 212 slides in the storage groove 211, and the rubber sheet 214 is stretched and deformed to prevent the model shells 210 from separating from each other. Then, the gap between the tops of the model shells 210 is blocked with a sponge block, and air is continuously fed until the outer sides of the model shells 210 are fitted, completing the wearing of the model. The size of the model can be adjusted by the electric push rod 207 and air pressure to adapt to down jackets of different sizes, so that when the model wears the down jacket during detection, it is more similar to the state when a human body wears it, thereby improving the accuracy of detection; During detection, pull the handle 218 to close the movable sealing plate 217, and send cold air through the cold air pipe 219 to lower the ambient temperature. Subsequently, start the sealing air pump 223, and the sealing air pump 223 inflates the sealing airbag 222. The sealing airbag 222 expands between the sealing pressure plate 221 and the fixed back plate 215 to close the gap at the connection and reduce the interference of the external environment. Both the fixed back plate 215 and the movable sealing plate 217 are made of transparent materials, and the heat preservation plate 220 is a transparent polycarbonate plate, which ensures the heat insulation effect and is convenient for observation; During the detection process, intermittently start the air inflation pump 230 and the resistance wire 228 to send heated air to ensure that the air temperature inside the rubber deformation frame 203 is maintained at 37°C. Excessive air is discharged through the electric valve 205 at the top of the pressure relief pipe 204 and through the transmission pipe 315 to maintain the volume and internal temperature of the model. The outer temperature sensor 224 is used to detect the temperature outside the model to detect the heat preservation ability of the down jacket, and the electric push rod 207 can be reciprocally started to change the volume of the model, so that the down jacket and the model alternately come into contact and separate. This method is similar to the state when a human body wears a down jacket during exercise, and this is used to simulate the state during exercise. Moreover, when a human body exercises, the internal heat production increases, which can be simulated by increasing the power of the resistance wire 228. At the same time, by simulating the increase in internal heat production of the human body and the state of the human body and the down jacket during exercise, the heat preservation effect during exercise is simulated, expanding the detection range. The heat preservation effect is known from the data difference between the internal temperature sensor 208 and the external temperature sensor 224. The smaller the temperature difference, the better the heat preservation effect, further improving the accuracy of detection; When it is necessary to simulate the environment, if it is necessary to simulate the condition of wind blowing, start the circulating air pump 307. The circulating air pump 307 extracts the internal air through the circulation holes 303. The air enters the air supply pipe 304 after passing from one partition plate 302 on one side of the circulation box 301 to the other partition plate 302 and then sprays out from the strip-shaped air outlet pipe 305. The size of the air outlet is adjusted by adjusting the power of the circulating air pump 307. The condition of blowing cold air is simulated through internal circulation. If it is necessary to simulate the rainy environment, open the annular dust-proof cover 314, pour clean water into the water tank 308, start the water supply pump 311. The water supply pump 311 extracts the clean water into the water supply pipe 312 through the water inlet hole 310 and then sprays it out by the nozzle 313 to wet the outer side of the down jacket. The size of the water spray is adjusted by adjusting the power of the water supply pump 311. Moreover, the driving motor 319 can be started to drive the gear ring 317 to rotate through the gear 320, and then drive the transmission pipe 315 in the sealing sleeve 316 to rotate. The transmission pipe 315 drives the rubber deformation frame 203 connected to the pressure relief pipe 204 to rotate, and then drives the whole model to rotate slowly to adjust the angles of the blowing and the water spraying to the outer side of the down jacket, and the environmental effect of simulating the blowing and raining is better; The adjustment and detection component 2 adapts to down jackets of different sizes by changing the volume of the model to improve the detection accuracy, and can simulate the state of the down jacket during movement, making the detection closer to the state of real human wearing, so as to further improve the detection accuracy. The simulation test component 3 simulates the states of blowing wind and raining. The two are combined with each other, making it closer to the heat preservation state of a real person wearing a down jacket in different environments, and will not cause damage to the human body, and the detection effect is better and more accurate.
