Description

Technical Field

[0001] The present application relates to the field of clothing fabric performance testing equipment, and in particular to a multi-zone independent gaseous sweat evaporation dummy. Background Art

[0004] The gaseous sweat evaporation manikin is an instrument that simulates the heat and moisture exchange between the human body and the environment. Its body consists of anatomical segments such as the head, chest, back, abdomen, buttocks, upper body, hands, lower body and feet. Since the amount of sweat in different parts of the human body is different, in order to accurately simulate the sweating environment of the human body, it is necessary to set up a separate sweat control device in each part of the human body.

[0005] In the prior art, a number of independently controlled detection modules are installed on various parts of a dummy, and then a tights is put on the outside of the dummy, and finally the clothing fabric to be tested is put on the outside of the tights. The amount of sweat is controlled by controlling the independent detection modules, and then the performance of the clothing fabric is tested. Since there is no corresponding partition between the independent detection modules, when the detection modules simulate the evaporation environment of sweat, the evaporated sweat will diffuse in the space surrounded by the fabric to be tested and the tights, and there is also a problem of mutual interference between the hot air flows, thereby affecting the results of the clothing performance test.

[0006] The fabric to be tested is mainly porous material, which is used to measure the air permeability and moisture resistance of the fabric to be tested.

[0024] To make the objectives, features, and advantages of this application more obvious and understandable, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of this application.

[0025] As Figure 1As shown in the figure, there are several functional areas 101 on the dummy. Among them, isolation areas 102 are provided between adjacent functional areas 101. A detection module 1 is provided on each functional area 101. The detection module 1 can simulate the temperature environment and sweating environment of the human body to test the performance of the fabric 100 to be detected. Since the temperature and sweating amount required for each functional area 101 are different, the detection module 1 in the functional area 101 needs to be independently controlled to achieve regional detection.

[0026] Specifically, an installation groove 1011 is provided at the functional area 101 of the dummy. The detection module 1 is snapped into the installation groove 1011. The detection end face of the detection module 1 extends out of the installation groove 1011 to abut against the fabric 100 to be detected, so as to support the fabric 100 to be detected and facilitate the contact between the fabric 100 to be detected and the sweat vapor simulated by the detection module 1.

[0027] During the performance detection of the fabric 100 to be detected, the fabric 100 to be detected needs to be sleeved on the outside of the dummy. At this time, the surface of the detection module 1 supports the fabric 100 to be detected. As Figure 8 shown, a detection space 103 for filling with sweat vapor is formed between the two. Since the detection modules 1 independently controlled are installed in different areas of the dummy and the temperature and sweating amount of each detection module 1 are different, after the fabric 100 to be detected is worn, the detection space 103 is a whole and it is impossible to partition the space area corresponding to the detection module 1. During the detection process, there is a risk of mutual interference in the areas corresponding to the adjacent detection modules 1.

[0028] To solve this problem, in this embodiment, as Figure 2 shown, a mesh-shaped isolation module 2 is installed at the isolation area 102. The isolation module 2 is composed of several independent isolation modules 21. Adjacent isolation modules 21 abut against each other to surround the periphery of the detection module 1. The detection space 103 is divided by the isolation module 21 to reduce the risk of mutual interference when adjacent detection modules 1 operate.

[0029] In order to be able to divide the detection space 103, in this embodiment, as Figure 3 shown, the detection module 1 includes a fixed part 211 and a movable part 212. The fixed part 211 is installed on the isolation area 102, and the movable part 212 can be snapped onto the fixed part 211 to clamp the fabric 100 to be detected between the fixed part 211 and the movable part 212. It should be noted here that after the movable part 212 is snapped onto the fixed part 211, the movable parts 212 on the multiple isolation modules 21 are connected end to end to completely cut off the adjacent functional areas 101, preventing the sweat evaporated inside the detection space 103 from flowing and affecting the detection result of the fabric 100 to be detected.

[0030] In order to realize the installation of the fixing part 211, in this embodiment, as Figure 4 shown, a settling groove 1021 recessed toward the inner cavity side of the dummy is provided on the isolation area 102. When the fixing part 211 is installed in the settling groove 1021, the side of the fixing part 211 away from the inner cavity of the warm body dummy is flush with the surface of the dummy.

[0031] Specifically, in this embodiment, as Figure 4 and Figure 6 shown, the fixing part 211 includes a fixing base 2111. Among them, a positioning strip 1022 is fixedly provided on the bottom wall of the settling groove 1021. When the fixing base 2111 is installed inside the settling groove 1021, the side wall of the fixing base 2111 abuts against the positioning strip 1022, thereby realizing the fixation of the fixing base 2111.

[0032] It should be noted that the side wall of the fixing base 2111 is in interference fit with the side wall of the positioning strip 1022.

[0033] Since the settling grooves 1021 on the dummy are distributed in a mesh pattern, when the fixing base 2111 is installed in the settling grooves 1021, it can completely fill the settling grooves 1021, improving the partition effect of the adjacent functional areas 101. In this embodiment, as Figure 4 and Figure 5 shown, the fixing base 2111 has a hexagonal structure. Among them, the fixing base 2111 is in a long strip shape and is arranged on one side of the detection module 1. The included angle formed by the adjacent side walls at the end of the fixing base 2111 is a right angle; alternatively, the intersection of the settling grooves 1021 is blocked by four fixing bases 2111 together.

[0034] In order to reduce the influence of the temperature between two adjacent functional areas 101, in this embodiment, the isolation module 2 can play an effect of temperature isolation and reduce the heat transfer between two adjacent functional areas 101.

[0035] Specifically, the isolation module 2 includes a temperature blocking member 213 for isolating temperature. Here, it should be noted that the fixing base 2111 can be used as one of the structures of the temperature blocking member 213. The fixing base 2111 is made of a ceramic fiber reinforced skeleton, and the characteristic of the low thermal conductivity of the ceramic fiber is utilized to improve the effect of temperature isolation.

[0036] It should be noted that each fixing part 211 corresponds to two groups of temperature blocking members 213. Among them, the two groups of temperature blocking members 213 are respectively arranged on both sides of the fixing part 211 to enhance the isolation effect of the isolation module 21.

[0037] Among them, as Figure 8 and Figure 9As shown, the temperature blocking member 213 includes a heating plate 2131 and a blocking plate 2132 , the side wall of the fixing seat 2111 is recessed to form an embedding groove 2112 , the temperature blocking member 213 is installed inside the embedding groove 2112 , and the blocking plate 2132 is installed between the heating plate 2131 and the inner wall of the sedimentation tank 1021 .

[0038] Among them, the heating plate 2131 is electrically connected to the central control unit through the power supply system. After the heating plate 2131 is powered on, the dummy, the fixing seat 2111 and the blocking plate 2132 are maintained at a stable temperature, which can assist the dummy isolation area 102 to maintain a test temperature of the fabric 100 to be tested, and avoid excessive temperature difference between the isolation area 102 and the functional area 101, which affects the measurement effect of the performance of the fabric 100 to be tested.

[0039] Among them, the use of the blocking plate 2132 can reduce the heat conduction from the functional area 101 to the fixing seat 2111, further improving the temperature blocking effect.

[0040] When the fabric 100 to be tested is placed on a dummy for performance testing, in order to make the fabric 100 to be tested fit on the fixing seat 2111, the fabric 100 to be tested and the testing module 1 form a sealed testing space 103, such as Figure 4 As shown, the movable portion 212 includes a buckling plate 2121, and a snap-fit ​​groove 21211 is provided on the buckling plate 2121. Specifically, as shown in FIG. Figure 8 As shown, after the blocking plate 2132 is installed inside the embedding groove 2112, the blocking plate 2132 extends out of the sedimentation groove 1021. When the movable part 212 is snapped onto the fixing seat 2111, the blocking plate 2132 is inserted into the snap-in groove 21211. At this time, a gap 200 is left between the blocking plate 2132 and the snap-in groove 21211 for inserting the fabric 100 to be tested.

[0041] During the inspection of the fabric 100 to be inspected, the fabric 100 to be inspected passes through the gap 200 and goes over the top of the blocking plate 2132 , so that the fabric 100 to be inspected and the fixing seat 2111 can be fitted together, and the inspection space 103 can be sealed.

[0042] Since the detection module 1 can simulate human sweating, when sweat evaporates and enters the detection space 103 formed by the detection module 1 and the fabric 100 to be detected, in order to reduce the interference caused by the flow of sweat vapor in two adjacent functional areas 101, the blocking plate 2132 is used to block the sweat vapor.

[0043] To improve the blocking effect of the sweat vapor flow and prevent the vapor from accumulating at the baffle 2132, a hydrophobic layer 21321 is coated on the baffle 2132. The hydrophobic layer 21321 is used to prevent the vapor from adsorbing on the baffle 2132 and the heating plate 2131. Among them, the baffle 2132 is located between the detection space 103 and the heating plate 2131. The baffle 2132 can solve the problem of the contact between the sweat vapor and the heating plate 2131 and reduce the risk of electric leakage of the heating plate 2131 caused by excessive humidity.

[0044] It should be noted here that, as Figure 8 shown, when the heating plate 2131 is placed inside the embedding groove 2112, the heating plate 2131 is flush with the surface of the dummy. The bottom wall of the fastening plate 2121 contacts the heating plate 2131, and the heating plate 2131 is sealed in the embedding groove 2112.

[0045] As the fastening plate 2121 presses the fabric to be detected 100 onto the fixing seat 2111, the detection space 103 is sealed. At this time, the sweat vapor flowing out of the detection module 1 can only flow out through the fabric to be detected 100.

[0046] Simulate natural wind and blow it towards the surface of the dummy to accelerate the evaporation of sweat. At this time, the vapor passing through the fabric to be detected 100 still has an impact. Therefore, in this embodiment, the isolation module 2 further includes a vapor blocking member 214. Among them, as Figure 4 、 Figure 5 and Figure 7 shown, the vapor blocking member 214 sequentially penetrates through the movable part 212 and the fixed part 211 and extends into the inner cavity of the dummy to form an air flow barrier 215, reducing the impact of the vapor flowing on the surface of the fabric to be detected 100.

[0047] Specifically, as Figure 5 and Figure 7 shown, the vapor blocking member 214 includes a first groove 2141, a second groove 2142 and an air suction pipe 2143. Among them, the first groove 2141 is a through groove that penetrates the fastening plate 2121. The second groove 2142 is arranged on the fixing seat 2111. The air suction pipe 2143 is connected to the second groove 2142 to suck the air inside the second groove 2142, so that the external air flow passes through the first groove 2141 and flows into the second groove 2142, thereby forming an air flow barrier 215. When the fastening plate 2121 is fastened on the fixing seat 2111, the first groove 2141 and the second groove 2142 are aligned with each other.

[0048] Among them, as Figure 7 and Figure 8As shown, it further includes an opening regulating valve 2144 installed on the suction pipe 2143. The other end of the opening regulating valve 2144 is connected to the suction pump. The opening regulating valve 2144 is electrically connected to the central control unit. The central control unit can adjust the opening of the opening regulating valve 2144, thereby controlling the suction volume of the suction pipe 2143, and further adjusting the wind speed entering the first tank 2141.

[0049] In order to improve the effect of forming the air flow barrier 215, in this embodiment, as Figure 7 and Figure 10 shown, it further includes a converging tank 2114 and a plurality of suction holes 2115. The converging tank 2114 is opened on the fixed seat 2111. The plurality of suction holes 2115 are arranged along the length direction of the second tank 2142 and connect the second tank 2142 with the converging tank 2114. The suction pipe 2143 is connected to the converging tank 2114.

[0050] With the above settings, when the suction pump is turned on, the air inside the converging tank 2114 is sucked through the suction pipe 2143 at this time, so a negative pressure environment is formed inside the converging tank 2114. The gas inside the second tank 2142 flows towards the converging tank 2114 through the multiple suction holes 2115 together, enabling the outside gas to uniformly flow through the first tank 2141 to the second tank 2142, improving the effect of forming the air flow barrier 215.

[0051] Since the fabric 100 to be detected is generally newly made ready-to-wear clothing and there are textile threads on the fabric. In order to prevent the threads on the fabric from flowing towards the suction pipe 2143 and blocking the opening regulating valve 2144, in this embodiment, as Figure 5 、 Figure 7 and Figure 8 shown, the fixed seat 2111 is further provided with a placement groove 2116 communicating with the first tank 2141. Among them, a filter screen 2117 for blocking the port of the second tank 2142 is arranged in the placement groove 2116. Above the filter screen 2117, there is a grille 2118 buckled with the placement groove 2116, thereby encapsulating the filter screen 2117 inside the placement groove 2116.

[0052] Since the outside wind speed in the test environment of the fabric 100 to be detected can be adjusted to adapt to different wind speed environments. At this time, in order to reduce the influence of the outside simulated wind speed on the steam flow, it is necessary to adjust the wind speed of the air flow barrier 215 to be consistent with the outside wind speed. In this embodiment, as Figure 7 and Figure 8 shown, it further includes a wind speed monitoring sensor 2145. The wind speed monitoring sensor 2145 is installed in the first tank 2141. At this time, the wind speed monitoring sensor 2145 is located outside the fabric 100 to be detected. The wind speed monitoring sensor 2145 is electrically connected to the central control unit.

[0053] With the above settings, the gas flow rate entering the first tank 2141 can be measured by the wind speed monitoring sensor 2145. When the gas flow rate at the first tank 2141 is different from the ambient wind speed of the fabric 100 to be detected, an electrical signal is sent to the opening regulating valve 2144 through the central control unit to adjust the opening of the opening regulating valve 2144 and control the air intake volume, so that the wind speed at the first tank 2141 is the same as the simulated ambient wind speed.

[0054] It should be noted here that the reason why the wind speed monitoring sensor 2145 is arranged in the first tank 2141 instead of the second tank 2142 is that the fabric 100 to be detected blocks the second tank 2142. When the wind speed monitoring sensor 2145 is arranged inside the second tank 2142, affected by the fabric 100 to be detected, the wind speed in the second tank 2142 is lower than that in the first tank 2141, making it difficult to adjust the opening of the opening regulating valve 2144 and resulting in inaccurate measurement results.

[0055] In order to make the fastening plate 2121 fasten on the fixed seat 2111 and reduce the risk of the fastening plate 2121 falling off, in this embodiment, as Figure 9 、 Figure 10 and Figure 11 shown, a puncture needle 21212 is provided on the fastening plate 2121, and a perforation 2113 is provided on the fixed seat 2111. When the fastening plate 2121 is fastened to the fixed seat 2111, the puncture needle 21212 penetrates the fabric 100 to be detected and is inserted into the perforation 2113, thereby realizing the fixation of the fastening plate 2121 and the fixed seat 2111.

[0056] Since the wind speed monitoring sensor 2145 is installed in the first tank 2141 and the fastening plate 2121 and the fixing part 211 are connected by a snap connection, it is difficult to realize the electrical connection between the wind speed monitoring sensor 2145 and the central control unit. Therefore, in this embodiment, as Figure 11 shown, the puncture needle 21212 has a hollow structure, and a first plug connector 2146 electrically connected to the wind speed monitoring sensor 2145 is arranged in the inner cavity of the puncture needle 21212. A second plug connector 2147 electrically connected to the central control unit is arranged inside the perforation 2113. When the fastening plate 2121 is fastened to the fixed seat 2111, the first plug connector 2146 is inserted into the second plug connector 2147 to form an electrical connection, so as to be able to transmit the wind speed signal monitored by the wind speed monitoring sensor 2145 to the central control unit for realizing the monitoring of the wind speed.

[0057] Since the heating plate 2131 is arranged in the embedding groove 2112, in order to supply power to the heating plate 2131, as Figure 7 and Figure 10As shown, an embedded wire hole 2119 is provided on the fixed seat 2111. One end of the embedded wire hole 2119 extends to the embedding groove 2112, and the other end of the embedded wire hole 2119 is provided on the bottom wall of the fixed seat 2111. It further includes a power supply connector 2120 which is arranged on the dummy. When the fixed seat 2111 is installed in the settlement groove 1021, the power supply connector 2120 is plugged into the embedded wire hole 2119.

[0058] As Figure 12 and Figure 13 shown, the detection module 1 includes a body temperature simulation device 3 and a sweating simulation device 4. Among them, the body temperature simulation device 3 is used to simulate the temperature environment of the human body and heat the dummy, and the sweating simulation device 4 is used to simulate the sweating condition of the dummy in the moving state or the stationary state.

[0059] Under normal circumstances, the sweating simulation device 4 is provided with a plurality of sweating holes on the surface of the dummy, and the sweat is diffused and evaporated through the sweating holes. When the fabric to be tested 100 is subjected to performance testing, a tight-fitting garment 5 needs to be sleeved outside the dummy. The tight-fitting garment 5 covers the sweating holes, and the sweat flowing out of the sweating holes diffuses outward through the tight-fitting garment 5, thereby expanding the range of sweat evaporation and improving the effect of sweating simulation. Then, the fabric to be tested 100 can be sleeved outside the tight-fitting garment 5.

[0060] When the traditional dummy is used to test the performance of the fabric to be tested 100, when the sweat of the sweating simulation device 4 flows onto the tight-fitting garment 5, the sweat will flow downward under the action of its own gravity, resulting in the accumulation of water at the feet of the dummy. The fabric to be tested 100 is directly attached to the tight-fitting garment 5, which will cause the sweat evaporation effect of the attached part of the tight-fitting garment 5 to become poor and affect the performance test of the fabric to be tested 100.

[0061] Therefore, in this embodiment, as Figure 13 shown, the sweating simulation device 4 includes a water supply mechanism 41, a diffusion mechanism 42, a reflux mechanism 43 and a steam diversion mechanism 44. Among them, the water supply mechanism 41 supplies water source to the diffusion mechanism 42, and the diffusion mechanism 42 is used to assist the evaporation of the water source. It should be noted that here, the evaporation of the water source is used to simulate the evaporation of sweat. In order to simplify the sweating evaporation simulation effect, the diffusion mechanism 42 is the same as the traditional principle of simulating sweat evaporation. The principle here is that the tight-fitting garment 5 accelerates the diffusion of water and then makes the liquid water evaporate. Since in the prior art, there is a problem that the liquid water on the tight-fitting garment 5 falls downward under the action of gravity, resulting in a relatively large amount of sweating. Usually, the accumulated water at the bottom of the dummy is manually recovered and then the test results are analyzed. To solve this problem, in this embodiment, the reflux mechanism 43 is used to recover the liquid water dripping from the diffusion mechanism 42.

[0062] Since the fabric 100 to be detected is in contact with the tight-fitting garment 5, which will affect the evaporation of water on the tight-fitting garment 5. Therefore, in this embodiment, a steam diversion mechanism 44 is provided. Specifically, when the performance of the fabric 100 to be detected is tested, the steam diversion mechanism 44 is arranged between the diffusion mechanism 42 and the fabric 100 to be detected, avoiding the contact between the fabric 100 to be detected and the diffusion mechanism 42 and improving the effect of sweat evaporation.

[0063] Among them, in order to achieve temperature control, in this embodiment, as Figure 13 and Figure 14 shown, the body temperature simulation device 3 includes a base 31 and a heating wire 32. The base 31 is installed in the installation groove 1011, and there is a card slot 104 between the side wall of the base 31 and the inner wall of the installation groove 1011. The heating wire 32 is arranged on the base 31.

[0064] Through the above settings, when power is supplied to the heating wire 32, the temperature of the heating wire 32 rises at this time, and thus the temperature of the detection module 1 will rise through the base 31, and then the human body temperature can be simulated.

[0065] It should be noted here that the heating wire 32 is electrically connected to the central control unit. The central control unit can be used to adjust the temperature of the heating wire 32, thereby controlling the temperature of the detection module 1 to maintain the stability of the temperature of the detection module 1.

[0066] In order to fix the heating wire 32, in this embodiment, as Figure 14 shown, a distribution groove 311 in a curved and distributed manner is arranged on the base 31, and the heating wire 32 is installed in the distribution groove 311.

[0067] Specifically, as Figure 15 shown, the water outlet of the water supply mechanism 41 is connected to the base 31, and the diffusion mechanism 42 is buckled on the base 31, so that the water flowing out of the water supply mechanism 41 flows onto the diffusion mechanism 42, providing suitable conditions for the evaporation of water. At this time, the heating wire 32 raises the temperature of the base 31, and this increase in temperature is conducive to the evaporation of water on the diffusion mechanism 42.

[0068] In order to achieve the evaporation of water on the diffusion mechanism 42, in this embodiment, as Figure 18 shown, the diffusion mechanism 42 includes a positioning frame 421. It should be noted here that the projection of the positioning frame 421 on the dummy is in a loop shape, and the tight-fitting garment 5 is installed on the inner wall of the positioning frame 421. Among them, the positioning frame 421 is clamped on the outside of the base 31, so that the inner wall of the positioning frame 421 abuts against the outer wall of the base 31 to realize the fixation of the positioning frame 421. At the same time, the tight-fitting garment 5 is in contact with the surface of the base 31, so that the water outlet of the water supply mechanism 41 is in contact with the tight-fitting garment 5, thereby transferring water to the tight-fitting garment 5.

[0069] Under normal circumstances, the tight-fitting garment 5 needs to cover the entire surface of the base 31. However, the water outlet of the water supply mechanism 41 is often a single hole or multiple holes, which may cause uneven lateral water distribution in the tight-fitting garment 5 and affect the wetting effect of the tight-fitting garment 5. Therefore, in this embodiment, as Figure 15 shown, the water supply mechanism 41 includes a water supply pipe 411, a water supply tank 412, and a flow splitting member 413. Specifically, the water supply tank 412 is arranged on the base 31 and is recessed towards the inside of the dummy. The water supply pipe 411 is arranged on the dummy. Among them, the water outlet end of the water supply pipe 411 is communicated with the water supply tank 412. Specifically, the water supply tank 412 is arranged along the width direction of the base 31. The flow splitting member 413 is installed in the water supply tank 412. The flow splitting member 413 can absorb the water provided by the water supply pipe 411 and diffuse it. After the positioning frame 421 is buckled on the base 31, the tight-fitting garment 5 is attached to the flow splitting member 413.

[0070] Through the above settings, when the water supply pipe 411 supplies water to the water supply tank 412, the water is absorbed by the flow splitting member 413 in the water supply tank 412. At this time, the water diffuses along the width direction of the base 31 in the flow splitting member 413, so as to spread the water over the tight-fitting garment 5, improve the water distribution effect, and facilitate the evaporation of water.

[0071] It should be noted here that the flow splitting member 413 can be a sponge.

[0072] In order to be able to recycle the water dripping on the tight-fitting garment 5, in this embodiment, as Figure 13 and Figure 16 shown, the reflux mechanism 43 includes a reflux pipe 431 and a reflux tank 432. Among them, the reflux tank 432 is arranged on the base 31 and is located at the bottom of the base 31. Specifically, the reflux tank 432 extends along the width direction of the base 31. The reflux pipe 431 is installed on the dummy. The reflux pipe 431 is communicated with the reflux tank 432. Among them, the bottom of the positioning frame 421 extends into the reflux tank 432.

[0073] It should be noted here that the bottom wall of the reflux tank 432 is inclined to direct the gathered liquid water flow towards the reflux pipe 431 to realize the recovery of the dripping water.

[0074] In order to be able to extend the bottom of the positioning frame 421 into the reflux tank 432, in this embodiment, as Figure 17 shown, the base 31 is provided with an avoidance groove 433 that communicates the reflux tank 432 with the card slot 104. When the positioning frame 421 is buckled on the base 31, the side of the positioning frame 421 passes through the avoidance groove 433 and is snapped into the reflux tank 432. Among them, the inner wall of the positioning frame 421 abuts against the outer wall of the base 31.

[0075] Specifically, a positioning strip 422 is arranged in the return flow tank 432 along the width direction of the base 31. When the bottom of the positioning frame 421 extends into the return flow tank 432, the inner wall of the bottom of the positioning frame 421 abuts against the positioning strip 422.

[0076] It should be noted here that the positioning strip 422 is arranged above the avoidance groove 433. A rubber layer is wrapped on the positioning frame 421. When the positioning frame 421 is inserted into the avoidance groove 433, the rubber layer is in interference fit with the avoidance groove 433, so as to block the avoidance groove 433 and prevent the dripping water from flowing out to the card slot 104 from the avoidance groove 433.

[0077] In order to facilitate the installation of the tight-fitting garment 5 on the positioning frame 421, in this embodiment, as Figure 19 shown, the diffusion mechanism 42 further includes a positioning retaining ring 423. Among them, the positioning retaining ring 423 is connected end to end to form a closed structure. Wrap the edge of the tight-fitting garment 5 on the positioning retaining ring 423 and tighten the tight-fitting garment 5, and then snap the positioning retaining ring 423 inside the positioning frame 421. The outer wall of the positioning retaining ring 423 and the inner wall of the positioning frame 421 are used to clamp the tight-fitting garment 5.

[0078] As Figure 16 and Figure 20 shown, a positioning post 4231 is fixedly arranged on the positioning retaining ring 423. After the tight-fitting garment 5 is wrapped on the positioning retaining ring 423, the tight-fitting garment 5 can be hooked on the positioning post 4231.

[0079] After the positioning retaining ring 423 is inserted into the positioning frame 421, the positioning frame 421 needs to be buckled on the edge of the base 31. In order to prevent the base 31 from ejecting the positioning retaining ring 423 from the positioning frame 421, in this embodiment, as Figure 16 and Figure 20 shown, the bottom wall of the bottom of the positioning frame 421 forms an included angle with the horizontal plane to form an abutting surface 4211. When the positioning retaining ring 423 and the tight-fitting garment 5 are installed on the positioning frame 421, the bottom edge of the positioning retaining ring 423 abuts against the abutting surface 4211, so as to limit the base 31 from ejecting the positioning retaining ring 423 from the front side of the positioning frame 421. At the same time, the positioning strip 422 abuts against the positioning retaining ring 423 to fix the positioning retaining ring 423 and solve the problem of the positioning retaining ring 423 shaking between the positioning frame 421 and the base 31.

[0080] It should be noted here that since the inner wall of the bottom of the positioning frame 421 is inclined at an angle, after the liquid water on the tight-fitting garment 5 drips down to the abutting surface 4211 of the positioning frame 421, the liquid water will flow into the return flow tank 432 along the inclined angle of the abutting surface 4211.

[0081] Since the positioning strip 422 abuts against the positioning retaining ring 423, at this time, the positioning strip 422 can prevent the liquid water from flowing back to the return groove 432 along the abutting surface 4211. Therefore, in this embodiment, as Figure 21 shown, a diversion groove 4212 is further provided on the abutting surface 4211. Among them, the diversion groove 4212 gathers the water on the inner wall of the bottom of the positioning frame 421, and then flows through the positioning strip 422 along the diversion groove 4212 to the return groove 432.

[0082] In order to make the steam evaporated by the diffusion mechanism 42 flow towards the fabric 100 to be detected, in this embodiment, as Figure 22 and Figure 23 shown, the steam diversion mechanism 44 includes an armor body 441. A buckling edge 4411 is provided at the edge of the armor body 441. A plurality of air holes 442 are provided on the armor body 441. The armor body 441 is buckled in the card slot 104 through the buckling edge 4411, and the buckling edge 4411 is located between the outer wall of the positioning frame 421 and the inner wall of the card slot 104.

[0083] Among them, an evaporation cavity 443 is left between the armor body 441 and the tight-fitting clothes 5. The air holes 442 are communicated with the evaporation cavity 443. The gas evaporated by the tight-fitting clothes 5 is filled inside the evaporation cavity 443. After that, the steam in the evaporation cavity 443 diffuses to the surface of the armor body 441 through the air holes 442, and then contacts the fabric 100 to be detected.

[0084] In order to prevent the fabric 100 to be detected from affecting the outflow of steam from the air holes 442, in this embodiment, as Figure 22 and Figure 23 shown, a plurality of protrusions 444 are provided on the armor body 441. A gas channel 445 is formed between two adjacent protrusions 444. Specifically, the gas channels 445 are interconnected to form a network structure covering the entire armor body 441. The air holes 442 are communicated with the gas channels 445. The protrusions 444 lift up the fabric to be detected, solving the problem that the fabric 100 to be detected blocks the air holes 442, and the gas channels 445 can accelerate the diffusion of steam on the surface of the armor body 441.

[0085] In order to be able to detect the temperature, in this embodiment, as Figure 22 shown, a detection hole 446 is further provided on the armor body 441. Among them, a temperature sensor can be inserted into the detection hole 446. The temperature sensor is electrically connected to the central control unit, so as to collect the temperature of the warm mannequin and facilitate the adjustment of the temperature of the heating wire 32.

[0086] Specifically, the protrusions 444 are in the shape of triangular pyramids.
