Description

Technical Field

[0001] This invention relates to the field of sweating and warming mannequin technology, specifically to a sweating and warming mannequin structure and a sweating and warming mannequin. Background Technology

[0002] In comfort testing of sportswear, close-fitting garments, and functional fabrics, the simulation of human sweating is a crucial factor affecting test accuracy. Current technologies typically use sweating mannequins to simulate human sweating. These mannequins usually consist of a mannequin body, a liquid supply system, and a heating device. The surface of the mannequin body has several sweat pores. The liquid supply system delivers simulated sweat to the sweat pores through tubing located inside the mannequin body, and the heating device simulates body temperature. However, current sweating mannequins have a limited number of sweat pores, and their spacing is relatively large. During simulation testing, this easily leads to the formation of discrete sweat spots or wet areas on the mannequin surface, failing to achieve the fine and uniform effect of simulating human sweating during exercise. Summary of the Invention

[0003] The purpose of this invention is to overcome the above-mentioned defects or problems in the prior art and to provide a sweating structure and a sweating and warming dummy, which, compared with conventional sweating and warming dummy in the prior art, has more and denser sweat pores, which can improve the fineness and uniformity of sweating.

[0004] In existing technologies, the challenge in increasing the density of sweat pores on sweating dummies lies not in how the pores are designed, but in how to effectively and efficiently deliver simulated sweat to these pores after increasing their density. In current sweating dummies, the sweat pores typically rely on silicone tubing within the dummy's internal cavity as infusion lines. As the number of sweat pores increases, more end-effectors need to be installed inside the dummy, especially in curved or confined spaces such as the arms, legs, sides of the torso, and shoulders, significantly increasing the difficulty of tubing installation, fixation, sealing, and maintenance. Furthermore, when numerous end-effectors extend from inside the dummy to different sweat pores, variations in tubing length, curvature, and pressure loss can easily lead to inconsistent sweat output from different pores. For curved skin areas, connecting thin tubes one by one to densely packed sweat pores can easily result in tubing bending, blockage, detachment, or leakage, affecting the long-term stability of the dummy.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: At least one embodiment discloses a sweating structure for a sweating, warming dummy, comprising a skin substrate, a sealing layer, and a liquid supply device. The skin substrate has an outer surface and an inner surface; the skin substrate has a plurality of sweat pores extending through a predetermined area, and corresponding to the predetermined area, a groove-shaped flow channel is recessed on the inner side of the skin substrate. The inner end of each sweat pore communicates with the bottom of the groove-shaped flow channel, and each groove-shaped flow channel corresponds to and connects to multiple sweat pores. The sealing layer is disposed on the inner side of the skin substrate, and the sealing layer at least covers the opening of the groove-shaped flow channel to form a liquid passage with the groove-shaped flow channel. The sealing layer has at least one liquid inlet communicating with the liquid passage. The liquid supply device includes an infusion tube communicating with the liquid inlet.

[0006] The applicant found that if the fluid supply line is placed directly inside the skin and leaks fluid outward through the opening in the tube wall, the location of the sweat pores is limited by the direction and diameter of the line, making it difficult to form a dense and uniform sweat point on the skin surface; in addition, the line and the skin require additional adhesion, covering or fluid absorption structures, which can easily lead to the sweating position being off or local fluid accumulation.

[0007] In the above design, since the grooved flow channel is directly recessed into the inner side of the skin substrate, and the sweat pores are connected to the bottom of the grooved flow channel through the skin substrate, after the liquid enters the skin area, it can first flow along the liquid passage formed by the grooved flow channel and the sealing layer, and then be discharged through multiple sweat pores corresponding to the same grooved flow channel. Therefore, the sweat pores do not need to be connected to separate end infusion tubes; multiple sweat pores can share the grooved flow channel formed on the skin substrate, thereby increasing the density of sweat pore arrangement while reducing the difficulty of internal tubing layout, assembly, and sealing of the dummy body. Because the grooved flow channel is a recessed structure of the skin substrate itself, its position can directly correspond to the sweat pores on the outer surface of the skin. The liquid flow path is jointly defined by the skin substrate and the sealing layer, thus allowing the liquid supply end to be closer to the sweat pores, reducing intermediate adsorption, diffusion, or transfer links, and thereby improving the certainty of the sweating location.

[0008] In the sweating structure of the sweating and warming dummy disclosed in at least one embodiment, preferably, the groove-shaped flow channel includes a main groove section and several branch groove sections; the main groove section extends along a first preset direction; one end of each branch groove section is connected to the main groove section and extends along a second preset direction, and each sweating hole is only connected to the branch groove section; the first preset direction and the second preset direction are different directions.

[0009] In the above design, since the trough-shaped flow channel is divided into a main channel section and a branch channel section, the liquid can first be transported along the main channel section in one direction, and then enter the branch channel section extending in another direction, and be discharged from the sweat pores corresponding to the branch channel section. This can form a two-dimensional liquid distribution path within a preset area of ​​the skin matrix, avoiding excessive differences in sweating between the proximal and distal ends caused by supplying liquid in only one direction, and also allowing the sweat pores to be closely arranged around the branch channel section.

[0010] In the sweating structure of the sweating and warming dummy disclosed in at least one embodiment, preferably, in the same groove-shaped flow channel, the branch groove segment is connected to the liquid inlet through the main groove segment, and each of the branch groove segments is arranged at intervals on both sides of the main groove segment along the first preset direction.

[0011] In the above design, since the inlet is first connected to the main channel, and the branch channels then obtain liquid through the main channel, the inlet does not need to be set for each branch channel separately. This reduces the number of openings on the sealing layer and the number of pipe connection points, lowering the risk of leakage. Simultaneously, the main channel can serve as a common liquid supply channel within the same channel, ensuring a relatively consistent liquid supply source for each branch channel. In this design, because the branch channels are spaced apart along the extension direction of the main channel and distributed on both sides of the main channel, the skin areas on both sides of the main channel can be covered by adjacent branch channels. This increases the coverage area of ​​a single channel within the preset area, shortens the path of liquid from the branch channels to each sweat pore, and facilitates a more balanced distribution of sweat pores within the same preset area.

[0012] In the sweating structure of the sweating and warming dummy disclosed in at least one embodiment, preferably, the skin substrate is provided with a plurality of grooved channels in the preset area, and each grooved channel is independent of the others; each grooved channel is respectively connected to at least one liquid inlet.

[0013] In the above design, since the multiple trough-shaped channels within the same preset area are independent of each other, and each trough-shaped channel corresponds to a liquid inlet, there is no direct liquid flow between different trough-shaped channels. This allows a large sweating area to be divided into multiple relatively independent liquid supply units, reducing pressure loss and uneven flow caused by excessively long single paths; when a trough-shaped channel becomes blocked or experiences a liquid supply abnormality, it is less likely to affect the sweating holes corresponding to other trough-shaped channels.

[0014] In the sweating structure of the sweating and warming dummy disclosed in at least one embodiment, preferably, in the same grooved flow channel, the width, depth and / or cross-sectional area of ​​the main groove section is greater than that of the branch groove section.

[0015] In the above design, since the main channel section is responsible for distributing liquid to multiple branch channels, its width, depth, and / or cross-sectional area are larger than those of the branch channels, enabling the main channel section to have a relatively greater liquid flow capacity and lower flow resistance. The branch channels are used for end-point distribution near the sweat pores, and their relatively smaller cross-sections allow for the arrangement of more end-point flow channels within a limited skin thickness. This forms a hierarchical flow channel structure that combines main channel liquid supply with end-point liquid distribution, improving the overall liquid supply stability.

[0016] In the sweating structure of the sweating warming dummy disclosed in at least one embodiment, preferably, the cross-section of the bottom of the groove-shaped channel is an arc shape convex toward the outer surface of the skin substrate.

[0017] With increased density of sweat pores, if the trough-shaped flow channel adopts a conventional square trough structure, the sweat pores will be directly opened on the flat bottom of the trough, forming an abrupt, interconnected structure of small holes between the trough bottom and the sweat pores. Due to the large number and small diameter of the sweat pores, this structure is susceptible to the effects of processing burrs, local misalignment, material deformation, impurity residue, or air bubble retention, which can weaken or even block some sweat pore inlets. At the same time, the flat bottom and angular areas of the square trough can easily form local stagnant zones, causing inconsistent liquid entry states among the multiple fine sweat pores, thus affecting the uniformity of sweating. In the above design, because the bottom of the trough-shaped flow channel is designed as an arc protruding towards the outer surface of the skin substrate, the inner end of the sweat pore is not designed as a planar opening structure on the bottom of the channel, but rather as an arc-shaped opening structure. This makes the connection between the sweat pore and the bottom of the trough-shaped flow channel smoother. When liquid flows through the trough-shaped flow channel, it can more smoothly converge to the inner end of the sweat pore along the arc-shaped bottom and more easily enter each sweat pore. At the same time, the arc-shaped bottom of the channel reduces the sharp corners and dead angles of the square bottom of the channel, reducing the impact of air bubbles, impurities, or processing burrs on the inlet of the small pore. Therefore, when the sweat pores are arranged in a relatively dense manner, it can improve the local connectivity stability between the trough-shaped flow channel and each sweat pore, reduce the risk of individual sweat pores not dispensing liquid or dispensing insufficient liquid, and improve the uniformity of sweating within the preset area.

[0018] In the sweating structure of the sweating and warming dummy disclosed in at least one embodiment, preferably, the skin substrate is provided with a plurality of the preset regions, and the arrangement density of the sweating pores in different preset regions is different; in the same preset region, the distance between two adjacent sweating pores is 2cm to 5cm.

[0019] In the above design, because the skin substrate is divided into multiple preset regions, and the density of sweat pores in different preset regions can be different, the number of sweat points can be adjusted according to the sweating test requirements of different body parts of the dummy. The limited distance range between sweat pores can avoid the sweat points from being too sparse, which would lead to local dispersion, and can also avoid the sweat points from being too small, which would weaken the skin substrate or increase the processing difficulty, thus balancing sweating uniformity and structural reliability.

[0020] In the sweating structure of the sweating and warming dummy disclosed in at least one embodiment, preferably, the liquid supply device further includes a plurality of liquid supply pumps, the skin substrate is provided with a plurality of the preset areas, each of the liquid supply pumps corresponds to at least one of the preset areas, and the liquid outlet of each of the liquid supply pumps is connected to the liquid inlet in the corresponding preset area through the liquid infusion pipe.

[0021] When the number of sweat pores is small, a single liquid supply pump can supply liquid to each sweat pore or sweating area through pipelines. However, when the number of sweat pores increases significantly and they are densely distributed on the skin substrate, a single liquid supply pump needs to handle the liquid supply needs of more sweat pores simultaneously. This results in a longer supply path and more branches after the pump, further amplifying the differences in flow resistance between different branches. This can easily lead to insufficient liquid supply to some areas of sweat pores and excessive liquid supply to others. Furthermore, the more sweat pores there are, the smaller the diameter and inlet space of each individual pore are usually. If the supply pressure or volume fluctuates significantly, it is more likely to cause problems such as no liquid supply, delayed liquid supply, or uneven liquid supply to distant, densely packed sweat pores. In the above design, since the liquid supply device includes multiple liquid supply pumps, and each liquid supply pump corresponds to at least one preset area, it is possible to distribute the liquid supply from a large number of sweat pores to different liquid supply pumps according to the preset areas. Each liquid supply pump only needs to deliver liquid to the inlet within its corresponding preset area, and then the liquid is distributed to multiple sweat pores via the trough-shaped flow channel within that preset area. This shortens the effective liquid supply path for a single pump, reduces the number of sweat pores that a single pump needs to cover, and lowers the flow distribution pressure when a large number of sweat pores are supplying liquid simultaneously. Therefore, with an increased number of sweat pores and a more dense arrangement, the differences in flow resistance between proximal and distal ends caused by single-pump supply can be reduced, allowing multiple sweat pores within each preset area to obtain liquid more stably, thereby improving the continuity and uniformity of sweating under conditions of densely packed sweat pores.

[0022] In the sweating structure of the sweating and warming dummy disclosed in at least one embodiment, preferably, the skin matrix includes an epidermal layer and a channel layer; the epidermal layer is disposed on the outside of the channel layer and has epidermal pores extending through it; the inner surface of the channel layer is recessed with the groove-shaped channel and has channel holes extending through it; the channel holes correspond one-to-one with the epidermal pores and cooperate to form the sweating pores.

[0023] In the above design, since the skin matrix includes an epidermal layer and a channel layer, the epidermal layer can be used to form an appearance and contact surface that closely resembles human skin, while the channel layer is used to form grooved channels and channel pores. Therefore, the skin surface simulation function and the internal channel forming function can be implemented in layers. The channel pores correspond one-to-one with the epidermal pores to form sweat pores, allowing liquid to reach the outer skin surface from the grooved channels inside the channel layer through the channel pores and epidermal pores. This ensures the biomimetic effect of the outer surface while facilitating the processing and sealing of the grooved channels.

[0024] In at least one embodiment, a sweating and warming dummy is also disclosed, wherein the sweating and warming dummy adopts the sweating structure of the sweating and warming dummy described in any of the above embodiments.

[0025] In the above design, because the sweating and warming dummy adopts the above-mentioned sweating structure, compared with the solution of arranging a large number of small terminal pipes inside the dummy, the sweating and warming dummy can reduce the complexity of the internal liquid supply system and allow sweat to be discharged more directly from multiple sweat pores on the skin substrate, thus making it more suitable for conducting tests related to the thermal and moisture comfort of sportswear, footwear, or human body.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are preferred embodiments of the present invention and should not be considered as excluding other embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0030] Unless otherwise expressly defined, the use of terms such as "first," "second," or "third" in the claims, description, and accompanying drawings of this invention is for distinguishing different objects and not for describing a specific order.

[0031] Unless otherwise expressly defined, in the claims, description, and accompanying drawings of this invention, the use of directional terms such as "center," "lateral," "longitudinal," "horizontal," "vertical," "top," "bottom," "inner," "outer," "upper," "lower," "front," "rear," "left," "right," "clockwise," and "counterclockwise" to indicate orientation or positional relationships is based on the orientation and positional relationships shown in the accompanying drawings and is only for the convenience of describing the invention and simplifying the description, and is not intended to indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the specific scope of protection of this invention.

[0032] Unless otherwise expressly defined, the terms "fixed connection" or "fixed connection" used in the claims, description and drawings of this invention should be interpreted broadly to refer to any connection in which there is no displacement or relative rotation relationship between the two parties, including non-removable fixed connection, detachable fixed connection, integral connection and fixed connection by other means or components.

[0033] In the claims, description and accompanying drawings of this invention, the terms "comprising," "having," and variations thereof are used to mean "including but not limited to."

[0034] In this invention, the "preset area" refers to a pre-defined sweating area on the skin substrate 100 based on testing requirements, human body part division, sweat distribution, or processing and assembly needs. The preset area can correspond to parts of the human body such as the head, torso, upper arm, forearm, thigh, calf, hand, and foot, or it can correspond to a local area within these parts. A skin substrate 100 can have one or more preset areas; the area, shape, number of sweat pores, and sweat pore density of different preset areas can be the same or different.

[0035] In this invention, "sweat pore 101" refers to a pore-like structure that penetrates the skin substrate 100 and allows simulated sweat to flow from the inside of the skin substrate 100 to the outside surface. The sweat pore 101 can be a round hole, an elliptical hole, a micro-slit hole, or other pore structures that allow liquid to pass through. The sweat pore 101 can be formed by drilling, laser processing, mold forming, needle punching, or other processing methods suitable for skin materials. The "inner end" of the sweat pore 101 refers to the end of the sweat pore 101 closest to the inner surface of the skin substrate 100; the "outer end" of the sweat pore 101 refers to the end of the sweat pore 101 closest to the outer surface of the skin substrate 100.

[0036] The "groove-shaped channel 110" described in this invention refers to a groove-shaped structure formed by the inner surface of the skin substrate 100 recessed into the interior of the skin substrate 100. Before the sealing layer 200 covers its opening, the groove-shaped channel 110 can appear as a groove opening towards the inner side of the skin substrate 100; after the sealing layer 200 covers the opening, the groove-shaped channel 110 and the sealing layer 200 together enclose and form a liquid passage for simulating the flow of sweat. Therefore, the groove-shaped channel 110 is different from a soft or rigid tube independently embedded inside the dummy, as at least a portion of its wall surface is formed by the skin substrate 100 itself.

[0037] In this invention, the "sealing layer 200" refers to a layered structure disposed inside the skin substrate 100 and used to cover the opening of the grooved flow channel 110. The sealing layer 200 can be a flexible membrane, elastic sheet, coating layer, adhesive layer, thermoforming layer, or composite layer. The sealing layer 200 at least covers the opening of the grooved flow channel 110, preventing the grooved flow channel 110 from opening further into the skin substrate 100, thereby defining a liquid passage together with the grooved flow channel 110. The sealing layer 200 may cover only the area where the grooved flow channel 110 is located, or it may cover all or most of the inner surface of the skin substrate 100.

[0038] The "liquid supply pump" described in this invention refers to a pump used to deliver simulated sweat from a storage container or main pipeline to the inlet of the skin substrate 100. The liquid supply pump can be a miniature diaphragm pump, a miniature peristaltic pump, a miniature gear pump, a plunger pump, or other pumps capable of delivering simulated sweat. The specific type of liquid supply pump does not constitute a necessary limitation on the scope of protection of this invention, as long as it can supply liquid to the inlet through the infusion tube.

[0039] Example This invention relates to a sweating, warming dummy, which employs a sweating structure. The sweating, warming dummy may include a skin assembly, a liquid supply device, a heating device, and a control system. The skin assembly forms at least a portion of the dummy's outer contour and creates sweating areas for simulated sweat expulsion; the liquid supply device delivers simulated sweat to the skin assembly; the heating device maintains a set temperature on the outer surface of the skin assembly; and the control system controls the operation of the liquid supply device and the heating device.

[0040] The following is a detailed description of the sweating structure used in this sweating, warming dummy.

[0041] Reference Figure 1 and Figure 2 , Figure 1 The structure of the arm portion of the sweating, warming dummy involved in this embodiment is shown. Figure 2 The cross-sectional structure of the arm portion of the sweating, warming dummy involved in this embodiment is shown.

[0042] Reference Figure 2 In this embodiment, the skin component includes a skin substrate 100 and a sealing layer 200. The skin substrate 100 has an outer surface and an inner surface. The outer surface of the skin substrate 100 is used to simulate the surface of human skin and can come into contact with the clothing, footwear, or outside air being tested; the inner surface of the skin substrate 100 faces the inside of the dummy. The skin substrate 100 can form the outline of the sweating and warming dummy as a whole shell structure, or it can be divided into multiple skin modules to form different parts of the sweating and warming dummy.

[0043] Reference Figure 2 In this embodiment, the skin substrate 100 includes an epidermal layer 120 and a channel layer 130. The epidermal layer 120 is disposed outside the channel layer 130 and is used to form the outer surface of the skin substrate 100. The epidermal layer 120 may be made of flexible silicone, skin-like elastic material, or elastic material with appropriate surface roughness to simulate the contact characteristics of human skin and allow the outer ends of the sweat pores 101 to discharge simulated sweat in a surface state closer to that of human skin.

[0044] The flow channel layer 130 is located inside the skin layer 120 and serves as the base layer for forming the outline of the dummy's body. That is, the flow channel layer 130 is not merely an additional lining to the flexible skin, but rather defines and maintains the local outline of corresponding parts of the dummy, such as the head, torso, upper limbs, and lower limbs, and provides a molding basis for the grooved flow channels 110 and flow channel holes 131. The inner side of the flow channel layer 130 can define the internal space of the dummy, which can be used to accommodate at least some components of the liquid supply device, heating device, and control system. Therefore, the flow channel layer 130 is preferably made of a material that is harder than the skin layer 120, such as hard resin, hard plastic, composite material, hard silicone, or other materials that can maintain the curved outline of the dummy's body and are suitable for processing the grooved flow channels 110. The skin layer 120 and the flow channel layer 130 can be connected by bonding, hot pressing, vulcanization, overmolding, secondary molding, or mechanical fixing.

[0045] The epidermal layer 120 has through-holes 121; the channel layer 130 has through-holes 131; the channel holes 131 correspond one-to-one with the epidermal holes 121 and cooperate to form sweat pores 101. Here, "one-to-one correspondence" means that each channel hole 131 is connected to one epidermal hole 121, together forming a complete sweat pore 101. The channel holes 131 and the epidermal holes 121 can be coaxially arranged, or they can be slightly offset within the range allowing liquid to pass through.

[0046] The skin substrate 100 has multiple preset areas. Each preset area can be divided according to human anatomical location, test area, or sweat distribution. For example, the preset areas can correspond to the head, chest, back, abdomen, upper arm, forearm, thigh, calf, etc., or to local areas of the above areas. The density of sweat pores 101 in different preset areas can be different to adapt to the testing needs of different body parts with different sweat volumes.

[0047] Reference Figure 1 The skin substrate 100 has a plurality of sweat pores 101 extending through each preset area. These sweat pores 101 extend from the inner side of the skin substrate 100 to its outer surface, allowing simulated sweat to be discharged through the pores 101 to the outer side of the skin substrate 100. The sweat pores 101 can be arranged in a matrix, staggered, honeycomb, array along the human body contour, or other arrangements suitable for curved skin within the preset areas. For skin areas with greater curvature, the spacing between the sweat pores 101 can be measured along the curved surface of the outer surface of the skin substrate 100, or it can be designed on a unfolded drawing based on equivalent distances and then converted to a curved surface.

[0048] Within the same preset area, the distance between two adjacent sweat pores 101 can be 2cm to 5cm. This distance can be understood as the center-to-center distance between adjacent sweat pores 101. For planar or near-planar areas, this distance can be the straight-line distance between adjacent sweat pores 101 on the outer surface of the skin substrate 100; for curved areas, this distance can be the curved distance along the outer surface of the skin substrate 100. This distance range allows the sweat pores 101 to be finer than those of a conventional sweating dummy, while still retaining the necessary solid material for the skin substrate 100 to ensure that the grooved flow channel 110, sweat pores 101, and sealing layer 200 can be reliably formed, sealed, and pressure-bearing.

[0049] Reference Figure 1 Corresponding to each preset area, the inner surface of the skin substrate 100 is recessed with a groove-shaped channel 110. The opening of the groove-shaped channel 110 faces the inner side of the skin substrate 100, and the bottom of the channel is located on the side of the groove-shaped channel 110 closer to the outer surface of the skin substrate 100. The inner end of the sweat pore 101 is connected to the bottom of the groove-shaped channel 110, so that the simulated sweat in the groove-shaped channel 110 can enter the sweat pore 101 from the bottom of the channel. Each groove-shaped channel 110 is connected to multiple sweat pores 101, so that multiple sweat pores 101 do not need to be connected to independent end pipes, but can share the groove-shaped channel 110 formed on the skin substrate 100 for liquid supply.

[0050] A sealing layer 200 is disposed on the inner side of the skin substrate 100. The sealing layer 200 at least covers the opening of the groove-shaped channel 110 to cooperate with the groove-shaped channel 110 to form a liquid passage. Specifically, the sidewalls and bottom of the groove-shaped channel 110 are formed by the skin substrate 100, and the sealing layer 200 covers the inward-facing opening of the groove-shaped channel 110, transforming the groove-shaped channel 110 from an open channel into a closed or substantially closed liquid passage. When simulated sweat flows within this liquid passage, it can be distributed along the groove-shaped channel 110 to multiple sweat pores 101.

[0051] The sealing layer 200 is provided with at least one liquid inlet communicating with the liquid passage. The liquid inlet can be an orifice penetrating the sealing layer 200, or a connector, nozzle, valve seat, or interface piece provided on the sealing layer 200. The position of the liquid inlet can correspond to the end, middle, or main channel section 111 of the trough-shaped flow channel 110. The liquid inlet can be connected to the infusion pipe by means of bonding, welding, hot pressing, snap-fitting, screwing, or integral molding.

[0052] In this embodiment, the trough-shaped flow channel 110 may include a main channel section 111 and several branch channel sections 112. The main channel section 111 extends along a first preset direction, and one end of each branch channel section 112 communicates with the main channel section 111 and extends along a second preset direction. The first preset direction and the second preset direction are different directions. The first preset direction can be understood as the main extension direction of the main channel section 111 within a preset area of ​​the skin substrate 100; the second preset direction can be understood as the direction in which the branch channel section 112 extends laterally, laterally, or in other different directions from the main channel section 111. The first preset direction and the second preset direction may be perpendicular to each other, or they may be set at an acute or obtuse angle, as long as they are different directions and can enable the branch channel section 112 to distribute liquid outward from the main channel section 111.

[0053] The main channel section 111 serves as the main liquid supply channel, while the branch channel sections 112 serve as the end distribution channel. The liquid inlet can communicate with the main channel section 111. After entering the main channel section 111, the liquid flows along a first preset direction and is distributed into multiple branch channel sections 112. Each sweating hole 101 preferably communicates only with a branch channel section 112; that is, the inner end of the sweating hole 101 is located at the bottom of the branch channel section 112, and not directly communicates with the main channel section 111. Thus, the main channel section 111 is mainly used to supply liquid to each branch channel section 112, and the branch channel sections 112 are mainly used to distribute liquid to multiple sweating holes 101, thereby forming a flow channel structure that combines main liquid supply and end sweating.

[0054] In the same trough-shaped flow channel 110, the branch trough section 112 is connected to the liquid inlet through the main trough section 111. That is to say, the liquid inlet does not need to be set for each branch trough section 112 separately, and multiple branch trough sections 112 can share the same main trough section 111 to obtain liquid. This structure can reduce the number of liquid inlets and the number of liquid delivery pipe connections on the sealing layer 200, and reduce the risk of leakage caused by too many openings in the sealing layer 200.

[0055] In the same trough-shaped flow channel 110, each branch channel segment 112 can be arranged at intervals on both sides of the main channel segment 111 along a first preset direction. Specifically, some branch channel segments 112 extend outward from one side of the main channel segment 111, and other branch channel segments 112 extend outward from the other side of the main channel segment 111. The branch channel segments 112 on both sides can be arranged opposite each other or staggered. The interval between two adjacent branch channel segments 112 can be determined according to the hole spacing of the sweat pores 101, the preset area, the strength of the skin substrate 100, and the requirements for uniformity of liquid supply.

[0056] In the same trough-shaped flow channel 110, the width, depth, and / or cross-sectional area of ​​the main channel section 111 can be larger than that of the branch channel section 112. Since the main channel section 111 needs to supply liquid to multiple branch channel sections 112, its flow rate is typically greater than that of a single branch channel section 112. Therefore, setting the main channel section 111 to have a larger width, depth, or cross-sectional area helps reduce the flow resistance within the main channel section 111. The branch channel sections 112 are located close to multiple sweat pores 101, and their cross-sections can be relatively small to allow for the arrangement of more branch channel sections 112 and sweat pores 101 within a limited skin thickness.

[0057] Within the same preset area, the skin substrate 100 can be provided with multiple grooved channels 110, and each grooved channel 110 is independent of the others. This independence means that different grooved channels 110 are not directly connected inside the skin substrate 100, and liquid cannot flow directly from one grooved channel 110 to another. Each grooved channel 110 is connected to at least one liquid inlet. By setting multiple independent grooved channels 110 within the same preset area, a large preset area can be divided into multiple liquid supply units. Each liquid supply unit corresponds to a smaller number of sweat pores 101, resulting in a shorter liquid supply path and more stable liquid distribution.

[0058] The cross-section of the bottom of the channel 110 can be an arc shape convex towards the outer surface of the skin substrate 100. Here, "cross-section" refers to the section obtained by cutting the channel 110 perpendicular to its extension direction. The bottom convex towards the outer surface of the skin substrate 100 means that the bottom is not a flat surface, but rather bulges or arches towards the outer surface of the skin substrate 100, either entirely or partially. The bottom can be a circular arc surface, an elliptical arc surface, a parabolic arc surface, or other continuous arc surface, and the transition between the bottom and the side walls can be achieved through rounded corners.

[0059] Because this embodiment has a large number of sweat holes 101 and a small hole spacing, if the trough-shaped flow channel 110 adopts a conventional square trough structure, the sweat holes 101 are usually directly opened on the flat bottom of the trough, forming abrupt small hole inlets between the trough bottom and the sweat holes 101. These inlets are easily affected by processing burrs, hole position deviations, local deformation of skin material, impurity residues, or air bubble retention. Especially when the sweat holes 101 are densely arranged, the processing tolerance of a single hole and the liquid inlet space become smaller, amplifying the above-mentioned effects. In this embodiment, the bottom of the trough-shaped flow channel 110 is set as an arc shape, allowing the liquid to converge along the arc surface of the trough bottom to the inner end of the sweat holes 101, reducing dead corners and local stagnant areas at the bottom of the trough, thereby improving the local connectivity stability between the trough-shaped flow channel 110 and the dense sweat holes 101.

[0060] The liquid supply device includes an infusion tube (not shown in the figure) connected to an inlet. The infusion tube can be made of silicone, polyurethane, PTFE, or other flexible materials. The liquid supply device may also include a storage container, multiple supply pumps, a flow controller, a check valve, a filter, a pressure sensor, and a controller. The storage container stores simulated sweat; the supply pumps deliver the simulated sweat through the infusion tube to the inlet; the flow controller regulates the flow rate of the corresponding supply path; the check valve reduces the risk of backflow; the filter reduces the risk of impurities entering the trough-shaped flow channel 110 and the sweat pores 101; and the pressure sensor detects the pressure status of the supply path.

[0061] In this embodiment, each liquid supply pump corresponds to at least one preset area, and the outlet of each liquid supply pump is connected to the inlet of the corresponding preset area through a delivery pipe. One liquid supply pump can correspond to one preset area or multiple preset areas; a preset area can be supplied with liquid by one liquid supply pump, or multiple liquid supply pumps can be used together depending on the area size or the number of sweat pores 101. Preferably, for preset areas with a large number of sweat pores 101, a large area, or where the amount of sweat needs to be independently controlled, an independent liquid supply pump is set up for liquid supply.

[0062] The liquid supply pump can be located inside the dummy space defined by the inner side of the flow channel layer 130, or outside the sweating and warming dummy. When the liquid supply pump is located inside the dummy space, it can be arranged close to the corresponding preset area to shorten the post-pump infusion path; when the liquid supply pump is located outside the sweating and warming dummy, it can be connected to the inlet of the corresponding preset area through a main pipeline or infusion pipe for maintenance and replacement. The inlet end of each liquid supply pump can be connected to a storage container, and the outlet end of each liquid supply pump can be connected to the inlet on the sealing layer 200 through an infusion pipe.

[0063] When the number of sweat pores 101 is small, a single liquid supply pump can supply liquid to multiple areas. However, when the number of sweat pores 101 increases significantly and they are densely distributed on the skin substrate 100, a single liquid supply pump needs to cover more sweat pores 101 simultaneously. This increases the number of liquid supply paths and branches after the pump, and also increases the difference in flow resistance between different paths. In this embodiment, multiple liquid supply pumps supply liquid to different preset areas, distributing a large number of sweat pores 101 into multiple relatively independent liquid supply units. Each liquid supply pump only needs to deliver liquid to the inlet in the corresponding preset area, and then the channel 110 in that preset area performs end-point distribution to multiple sweat pores 101.

[0064] A heating device is used to maintain a set temperature on the skin area of ​​the sweating, warming dummy. The heating device can be located inside the skin substrate 100, inside the sealing layer 200, inside the flow channel layer 130, or embedded in the skin assembly. The heating device can be an electric heating film, resistance wire, flexible heating pad, heating plate, or other structure capable of supplying heat to the skin area. The heating device is preferably used in conjunction with a temperature sensor, which can be located near the skin substrate 100 or embedded in the skin assembly, to detect the skin surface temperature or the temperature of the skin area. The control system can separately control the heating device and the liquid supply pump, allowing different skin areas of the dummy to simulate sweating at a set temperature and a set liquid supply volume.

[0065] When manufacturing the sweating, warming dummy of this embodiment, a preset area on the skin substrate 100 can be determined first according to the target testing purpose, and the number of sweat pores 101, the pore spacing, and the arrangement of the grooved flow channels 110 in each preset area can be determined. Then, the skin substrate 100 is prepared. Specifically, a relatively rigid flow channel layer 130 can be prepared first, so that the flow channel layer 130 forms the basic outline of the corresponding part of the dummy body, and grooved flow channels 110 are formed on the inner side of the flow channel layer 130; then, an epidermal layer 120 is provided on the outer side of the flow channel layer 130, so that the epidermal layer 120 covers the flow channel layer 130 and forms an outer surface for simulating human skin.

[0066] After forming the grooved channel 110, sweat pores 101 can be formed on the skin substrate 100. The sweat pores 101 should extend from the outer surface of the skin substrate 100 to the bottom of the grooved channel 110. If a structure of epidermal layer 120 and channel layer 130 is used, the epidermal pores 121 and channel pores 131 are correspondingly connected. After the sweat pores 101 are formed, the pore openings can be deburred, cleaned, or inspected for patency to reduce the risk of clogging during subsequent use.

[0067] Then, the sealing layer 200 is applied to the inner side of the skin substrate 100. The sealing layer 200 covers the opening of the grooved flow channel 110 and is sealed to the skin substrate 100. The sealing connection method can be selected according to the material, such as bonding with silicone adhesive, hot pressing, vulcanization, ultrasonic welding, or mechanical pressing. There should be no bypass leakage between the sealing layer 200 and the skin substrate 100, ensuring that the liquid flows mainly along the grooved flow channel 110 after entering the inlet.

[0068] Subsequently, the inlet is connected to the infusion tube. The inlet can be pre-set on the sealing layer 200 or opened after the sealing layer 200 is installed. One end of the infusion tube is connected to the inlet, and the other end is connected to the supply pump or other components of the supply device. For multiple preset areas, multiple infusion tubes and multiple supply pumps can be set separately, so that each preset area forms a relatively independent supply path. After assembly, water or simulated sweat can be introduced into the inlet, and it can be observed whether liquid is discharged from the multiple sweat holes 101 corresponding to the groove-shaped flow channel 110, in order to test the sealing performance and sweat consistency.

[0069] In use, the control system first activates the heating device to bring the outer surface of the skin substrate 100 to the target test temperature. Then, it activates the liquid supply pump for the corresponding preset area, allowing simulated sweat to enter the corresponding inlet via the infusion tube. After entering the inlet, the simulated sweat flows through the liquid passage formed by the trough-shaped flow channel 110 and the sealing layer 200, and flows along the main trough section 111 and the branch trough section 112. The liquid is distributed to multiple sweat pores 101 within the branch trough section 112 and discharged from the sweat pores 101 to the outer surface of the skin substrate 100. Thus, this sweating warming dummy can maintain the skin surface temperature while achieving zoned liquid supply and surface sweating simulation under the condition of fine sweat pores 101.

[0070] Without departing from the concept of the present invention, the specific shape of the grooved channel 110 can be adjusted according to the arrangement of the skin area and the sweat pores 101. For example, the grooved channel 110 can be a straight channel, a curved channel, a zigzag channel, an annular channel, a dendritic channel, a herringbone channel, or a grid channel. As long as the grooved channel 110 is recessed inside the skin substrate 100, and the opening of the channel is covered by the sealing layer 200 to form a liquid passage, and the sweat pores 101 are connected to the grooved channel 110, the basic technical effect of the present invention can be achieved.

[0071] Without departing from the concept of the present invention, the sealing layer 200 can be a freestanding sheet, a coated and cured layer, or a cover layer formed by secondary molding with the skin substrate 100. The sealing layer 200 can cover only the area where the groove-shaped flow channel 110 is located, or it can cover the entire inner surface of the skin substrate 100. The sealing layer 200 can also be combined with a heating film or a heat insulation layer to form a multifunctional inner layer.

[0072] Without departing from the inventive concept, the number, location, and control method of the liquid supply pumps can be adjusted. For example, multiple liquid supply pumps can be centrally arranged in a pump box outside the dummy, or they can be distributed in the internal space of the dummy defined by the inner side of the flow channel layer 130, and set close to the corresponding preset area. The liquid supply pumps can supply liquid continuously or intermittently; they can supply liquid at a constant flow rate or change the flow rate according to the test procedure.

[0073] Without departing from the concept of the present invention, the skin substrate 100 can cover the entire sweating and warming dummy, or it can only cover a local area of ​​the dummy body. For example, the sweating structure of the present invention can be used separately on the torso, arms, legs, or feet. The skin substrate 100 on different parts can adopt the same arrangement of the grooved channels 110, or it can be designed separately according to the curved shape of the corresponding parts.

Modifications, equivalent substitutions, or other improvements to the embodiments of this invention or a portion thereof that can be obtained by those skilled in the art through logical analysis, reasoning, or limited experimentation, based on the teachings of this invention or the foregoing embodiments, in conjunction with common knowledge, general technical knowledge, and / or existing technology, should all be included within the scope of protection of this invention.
