Description

Technical Field

[0001] The present application relates to the technical field of fabric thermal insulation performance testing, and specifically to a device for testing the thermal insulation performance of skin-friendly flannel fabric. Background Art

[0002] Flannel fabric is a soft and velvety (cotton) wool fabric woven with coarsely carded (cotton) yarn. It is covered with a layer of plump, fine and clean velvet inside, with no visible weave pattern and a soft and smooth feel. It is a common fabric in modern home life. After production, its thermal insulation performance needs to be tested to ensure the quality of the product.

[0003] According to the thermal insulation performance tester for warm cashmere fabric disclosed in Chinese Patent Publication No. CN217954322U, the patent uses the arrangement of lifting columns, an upper pressure frame, and a groove to stably fix the fabric, thereby facilitating thermal insulation performance testing. However, the patent still has certain shortcomings in actual application. During the thermal insulation test, the inside of the fabric is heated by a heating plate, and the other side of the fabric is blown by a blower. This testing method causes part of the heat transferred by the heating plate to be carried away by the flowing air. Warm fabrics are mostly used in home quilts and blankets. When used in clothing, the outer side is mostly windproof fabric, so that the other side of the fabric is not blown by excessive wind force. As a result, the patent cannot effectively simulate the actual state of human use. In addition, the method of fixing the fabric by the structural coordination of the upper pressure frame, the first spring, and the lifting column is very cumbersome, and its structural composition can be optimized. In this regard, the present application proposes a skin-friendly flannel fabric thermal insulation performance tester based on the simplification of the structure and the simulation of a test scenario that is more in line with actual use. Utility Model Content

[0004] In response to the shortcomings of the existing technology, the present application provides a skin-friendly flannel fabric thermal insulation performance testing device, which has the advantages of simple structure and easy operation, and can simulate scenarios that are more suitable for human use. It solves the shortcomings of the existing fabric thermal insulation performance testing machine in actual use, such as the structure is relatively cumbersome and cannot effectively simulate the warmth state of the human body during actual use.

[0005] To achieve the above objectives, the present application provides the following technical solutions: a device for testing the thermal insulation performance of skin-friendly flannel fabrics, comprising a base, a box mechanism mounted on the top of the base, a test assembly mounted inside the box mechanism, and a controller fixedly mounted on the top of the base;

[0006] The box structure includes a test box fixed to the top of the base, an inner box located inside the test box, an insulation layer filled between the inner side of the test box and the outer side of the inner box, and a door assembly movably installed on the front of the test box;

[0007] The test assembly includes a simulation box that is detachably connected to the inner bottom wall of the inner box, a heating plate fixedly installed on the inner bottom wall of the simulation box, a limiting groove opened on the outside of the simulation box, an elastic band inserted into the inside of the limiting groove, several temperature sensors fixedly installed on the inside of the simulation box, and two temperature monitoring probes fixedly installed on the inside of the inner box.

[0008] By adopting the above technical solution, the structure is simple and the operation is convenient, and at the same time, a scene that is more suitable for human use can be simulated.

[0009] Furthermore, the door assembly includes a sealed door hinged to the front of the test box by a hinge, a sealing ring bonded to one side of the back of the sealed door, and two tempered glasses passing through and fixedly installed on the front of the sealed door.

[0010] By adopting the above technical solution, it is convenient for outsiders to observe.

[0011] Furthermore, the front of the inner box is open, the sealing ring is inserted into the inner side of the opening on the front of the inner box, and a lock is fixedly installed between the sealing door and the outer side of the test box.

[0012] By adopting the above technical solution, the sealed door can be locked to the test box through the lock, and the sealing ring can achieve a good heat preservation effect, making it difficult for external factors to affect the interior of the test box.

[0013] Furthermore, the two tempered glasses are respectively located on the front side and the back side of the sealed door, and a vacuum interlayer is provided between the opposite sides of the two tempered glasses.

[0014] By adopting the above technical solution, the two tempered glasses and the vacuum interlayer can achieve the effect of heat preservation. At the same time, the situation inside the inner box can be easily checked through the tempered glass.

[0015] Furthermore, the thermal insulation layer is a foamed polyethylene layer, and the top of the simulation box is open.

[0016] By adopting the above technical solution, a good thermal insulation effect can be achieved. After the fabric is covered on the top of the simulation box, the heat can be discharged through the fabric, thereby facilitating the testing experiment.

[0017] Furthermore, the temperature sensors are divided into two groups, an upper group and an lower group, and the temperature sensors in each group are distributed in a ring shape on the inner side of the simulation box.

[0018] By adopting the above technical solution, the temperature sensor can monitor various spaces inside the simulation box.

[0019] Furthermore, the limiting groove is opened around the outer side of the simulation box and is annular, and the inner side of the limiting groove is arc-shaped.

[0020] By adopting the above technical solution, the elastic band can be inserted into the inner side of the limiting groove and can bind the fabric.

[0021] Furthermore, the two temperature monitoring probes are symmetrically distributed on the left and right, and the temperature monitoring probes are located above the simulation box.

[0022] By adopting the above technical solution, the temperature monitoring probe can effectively sense the temperature inside the inner box.

[0023] Compared with the existing technology, the technical solution of this application has the following beneficial effects:

[0024] The skin-friendly flannel fabric thermal insulation performance test device has a simple structure and is easy to operate through the coordinated use of the box mechanism on the top of the base and the test components. It can also simulate a scene that is more in line with human use, so that testers can test the thermal insulation effect of the fabric simply and conveniently. At the same time, its test scene is very consistent with the scene during actual use, so that the test data can match the feeling of the human body during use, ensuring the validity of the data and greatly improving the practicality of the fabric thermal insulation performance test device.

[0030] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0031] See also Figures 1 to 4 The present application provides a technical solution: a skin-friendly flannel fabric thermal insulation performance testing device, comprising a base 1, a box mechanism 200 installed on the top of the base 1, a test component 300 installed inside the box mechanism 200, and a controller 4 fixedly installed on the top of the base 1; through the coordinated use of the box mechanism 200 on the top of the base 1 and the test component 300, the structure is simple and easy to operate, and at the same time, it can simulate a scene that is more in line with human use, so that testers can test the thermal insulation effect of the fabric simply and conveniently. At the same time, its test scene is very close to the scene in actual use, so that the test data can match the feeling of the human body during use, ensuring the validity of the data, and greatly improving the practicality of the fabric thermal insulation performance testing device.

[0032] In this embodiment, the box mechanism 200 is a structure for providing an effective testing environment.

[0033] like Figure 1 、 Figure 3 and Figure 4 As shown, the box structure 200 includes a test box 201 fixed to the top of the base 1, an inner box 203 located inside the test box 201, an insulation layer 202 filled between the inner side of the test box 201 and the outer side of the inner box 203, and a door assembly movably installed on the front of the test box 201; the door assembly includes a sealed door 204 hinged to the front of the test box 201 by a hinge, a sealing ring 205 bonded to one side of the back of the sealed door 204, and two tempered glasses 206 passed through and fixedly installed on the front of the sealed door 204.

[0034] It should be noted that the front of the inner box 203 is open, and the sealing ring 205 is inserted into the inner side of the front opening of the inner box 203. A lock is fixedly installed between the sealing door 204 and the outer side of the test box 201, so that the sealing door 204 can be locked to the test box 201 through the lock, and the sealing ring 205 can achieve a good thermal insulation effect, so that external factors are not easily affected by the interior of the test box 201.

[0035] In addition, two tempered glasses 206 are respectively located on the front side and the back side of the sealed door 204, and a vacuum interlayer is provided between the opposite sides of the two tempered glasses 206, so that the two tempered glasses 206 and the vacuum interlayer can have a heat preservation effect. At the same time, the tempered glasses 206 are used to facilitate viewing the situation inside the inner box 203. The heat-insulating layer 202 is a foamed polyethylene layer, which can have a good heat-insulating effect.

[0036] In this embodiment, the testing component 300 is a structure for testing the thermal insulation performance of flannel fabric.

[0037] like Figure 1 and Figure 2 As shown, the test assembly 300 includes a simulation box 301 detachably connected to the inner bottom wall of the inner box 203, a heating plate 302 fixedly installed on the inner bottom wall of the simulation box 301, a limiting groove 303 opened on the outside of the simulation box 301, an elastic band 304 inserted into the inner side of the limiting groove 303, a plurality of temperature sensors 305 fixedly installed on the inner side of the simulation box 301, and two temperature monitoring probes 306 fixedly installed on the inner side of the inner box 203.

[0038] It should be noted that the top of the simulation box 301 is open, so that after the fabric covers the top of the simulation box 301, the heat can be discharged through the fabric, thereby facilitating the testing experiment. Several temperature sensors 305 are divided into two groups, upper and lower. Each group of temperature sensors 305 is distributed in a ring shape on the inner side of the simulation box 301, so that the temperature sensor 305 can monitor each part of the space inside the simulation box 301.

[0039] In addition, the limiting groove 303 is opened around the outer side of the simulation box 301 and is annular. The inner side of the limiting groove 303 is arc-shaped, so that the elastic band 304 can be inserted into the inner side of the limiting groove 303 and can bind the fabric. The two temperature monitoring probes 306 are symmetrically distributed on the left and right. The temperature monitoring probes 306 are located above the simulation box 301, so that the temperature monitoring probes 306 can effectively sense the temperature inside the inner box 203.

[0040] It should also be noted that the temperature sensor 305 and the temperature monitoring probe 306 can send the monitored data to the controller 4 for reception, and the heating plate 302 can be temperature-controlled by the controller 4. The control method is an existing public technology, so it will not be elaborated in detail.

[0041] The working principle of the above embodiment is:

[0042] When it is necessary to test the thermal insulation performance of the flannel fabric, the fabric is placed flat on the top of the simulation box 301 so that the fabric covers the top opening of the simulation box 301 and is wrapped around the outside of the simulation box 301. The fabric and the outside of the simulation box 301 are directly bound by the elastic band 304, and the elastic band 304 is inserted into the inner side of the limit groove 303. At this time, the inside of the simulation box 301 can be regarded as a human body. The sealing door 204 is closed, the heating plate 302 is started and its temperature is controlled between 36°C and 37°C by the controller 4, simulating the actual state of the human body as much as possible. The temperature sensor 305 can monitor the time required for each part of the simulation box 301 to stably reach the temperature range and remain stable. At the same time, under the action of the temperature monitoring probe 306, the time required for the temperature of the fabric overflow to be sensed by the temperature monitoring probe 306 inside the inner box 203 can be monitored, or the maximum sensed temperature within a certain period of time can be detected, thereby achieving an effective test of the thermal insulation performance of the flannel fabric.

[0043] Compared with the existing technology, the skin-friendly flannel fabric thermal insulation performance testing device has a simple structure and is easy to operate through the cooperation between the box mechanism 200 on the top of the base 1 and the test component 300. At the same time, it can simulate a scene that is more in line with human use, so that testers can test the thermal insulation effect of the fabric simply and conveniently. At the same time, its test scene is very consistent with the scene during actual use, so that the test data can match the feeling of the human body during use, ensuring the validity of the data, and greatly improving the practicality of the fabric thermal insulation performance testing device, solving the shortcomings of the existing fabric thermal insulation performance testing machine in actual use, which is relatively complicated in structure and cannot effectively simulate the thermal insulation state of the human body during actual use.
