Abstract
Description
Technical Field
[0001] The invention relates to the technical field of down jacket performance testing, in particular to a down jacket light irradiation heat storage and temperature locking performance testing device. Background Art
[0002] In the down clothing industry, light heat storage and temperature locking performance is one of the important indicators to measure the warmth retention efficiency of products. It is of great significance to improve product competitiveness and meet the diverse needs of consumers.
[0003] At present, the detection of down jackets' light heat storage and temperature locking performance mainly relies on temperature measuring equipment such as infrared thermal imagers. These devices capture infrared radiation on the surface of down jacket samples and convert it into a visual temperature distribution map, providing an intuitive basis for performance evaluation. Although infrared thermal imagers can efficiently and quickly obtain temperature information on the surface of down jacket samples, they can only obtain surface temperature data of down jacket samples and cannot penetrate into the interior of the samples. The thermal insulation performance of down jackets not only depends on their surface thermal resistance characteristics, but is also closely related to the heat storage capacity of the down fibers inside them and the synergistic effect of the fabric and down. It is difficult to fully and accurately reflect the light heat storage and temperature locking performance of down jackets based solely on the sample surface temperature data.
[0004] Therefore, the present invention proposes a down jacket light heat storage and temperature locking performance detection device to solve the above problems. Summary of the invention

[0011] In an optional solution: the transparent tube is U-shaped and has scale lines on it, and the liquid column is a colored liquid column.
[0012] In an optional solution: the air guide part and the air collecting plate are both made of thermal insulation material, and the monitoring component is made of thermal conductive material.

The box body is provided with a negative pressure fan for forming a negative pressure in the down suction cavity to absorb down.
[0016] Compared with the prior art, the beneficial effects of the embodiments of the present invention are as follows:
[0017] Based on the principle of thermal expansion and contraction of mercury, the down jacket sample heats up due to heat storage due to light, causing the mercury to expand due to the heat, thereby pushing the sealed piston to inject air into the air collecting disk. The air pressure inside the air collecting disk increases, thereby pushing the liquid column toward the open end of the transparent tube to maintain air pressure balance. The greater the distance the liquid column moves, the higher the temperature of the down jacket sample, that is, the better the heat storage property due to light. After the light source is turned off for a certain period of time, the down jacket sample dissipates heat and heats up, causing the mercury to shrink. Under the action of air pressure, the sealed piston returns to its position and draws air from the air collecting disk. The air pressure inside the air collecting disk decreases, thereby causing the liquid column to move back toward the air collecting disk. The smaller the return distance of the liquid column, the less heat dissipated by the down jacket sample, that is, the better the temperature locking property. The temperature sensing parts of multiple monitoring components are evenly distributed inside the down jacket sample for temperature monitoring to ensure that the temperature data is comprehensive and accurate, thereby accurately reflecting the heat storage and temperature locking performance of the down jacket due to light.

The temperature sensing section 1302 is filled with mercury 1304 and is provided with a sealing piston 1305. When the two groups of the clamps 3 are in the preparation position, the down jacket sample is not in contact with the multiple monitoring components 13. When the two groups of the clamps 3 are in the detection position, the temperature sensing sections 1302 of the multiple monitoring components 13 are all located inside the down jacket sample. A connected transparent tube 17 is provided at the bottom of the gas collecting plate 16. The end of the transparent tube 17 away from the gas collecting plate 16 is open, and a liquid column 18 is provided in the transparent tube 17.
[0029] The detection cavity 202 is provided with an adapted cavity cover 4 , and the cavity cover 4 is provided with a light source component 7 for simulating illumination of a down jacket sample.
[0030] First, place the down jacket sample in the detection chamber 202 and clamp it with two sets of clamps 3 (when clamping the down jacket sample, the two sets of clamps 3 are in the preparation position. The clamps 3 are prior art. As long as they can clamp and fix the two sides of the down jacket sample, they will not be limited or elaborated here). Then, the chamber cover 4 is closed, and the two sets of clamps 3 are switched from the preparation position to the detection position, so that the temperature sensing parts 1302 of multiple monitoring components 13 are all inserted into the down jacket sample. The position of the liquid column 18 in the transparent tube 17 at this time is recorded (recorded as the initial position), and then the light source component 7 is turned on to illuminate the down jacket sample for a certain period of time. After the illumination time is reached, the position of the liquid column 18 in the transparent tube 17 at this time is recorded (recorded as the heat storage position). Under the principle of thermal expansion and contraction of mercury, the down jacket sample is heated up due to heat storage due to light, causing the mercury 1304 to expand due to heat, thereby pushing the sealing piston 1305 to inject gas into the gas collecting plate 16. , the air pressure inside the air collecting disk 16 increases and pushes the liquid column 18 to move toward the open end of the transparent tube 17 to maintain the air pressure balance. The greater the moving distance of the liquid column 18, the higher the temperature of the down jacket sample, that is, the better the light heat storage property. After the light source 7 is turned off for a certain period of time, the position of the liquid column 18 in the transparent tube 17 at this time is recorded (recorded as the temperature locking position). The heat dissipation and temperature rise of the down jacket sample causes the mercury 1304 to shrink. Under the action of air pressure, the sealing piston 1305 returns to its position and draws air from the air collecting disk 16. The air pressure inside the air collecting disk 16 decreases and the liquid column 18 moves back to the air collecting disk 16. The smaller the return distance of the liquid column 18, the less heat the down jacket sample loses, that is, the better the temperature locking property. The temperature sensing parts 1302 of multiple monitoring parts 13 are evenly distributed inside the down jacket sample for temperature monitoring to ensure that the temperature data is comprehensive and accurate, thereby accurately reflecting the light heat storage and temperature locking performance of the down jacket.
[0031] Furthermore, one end of the temperature sensing portion 1302 away from the air guiding portion 1301 is provided with a spike head 1303 for piercing the outer fabric layer of the down jacket sample.
[0032] Furthermore, the transparent tube 17 is U-shaped and is provided with scale lines 19. By setting the scale lines 19, the moving distance of the liquid column 18 can be accurately observed and recorded. The liquid column 18 is a colored liquid column, which is convenient for detection personnel to observe.
[0033] Furthermore, the air guide portion 1301 and the air collecting plate 16 are both made of heat insulating materials, and the monitoring element 13 is made of heat conductive materials. Since gas will also expand and cool due to heat, the air guide portion 1301 and the air collecting plate 16 are thermally insulated to prevent heat other than the down jacket sample from being transferred to the air guide portion 1301 and the air collecting plate 16, thereby preventing the liquid column 18 from moving due to "external" temperature changes, and further ensuring the accuracy of the detection data.
[0034] See also Figure 1In one embodiment of the present invention, the detection device also includes a telescopic member 5 for driving the cavity cover 4 to rise and fall to realize its opening and closing. The telescopic member 5 can be a hydraulic rod, an electric telescopic rod, etc., which belongs to the existing mature technology, so it is not limited or elaborated here.
[0035] See also Figure 1 and Figure 6 In one embodiment of the present invention, the detection device also includes a humidity control unit for controlling the humidity inside the detection chamber 202, a temperature control unit for controlling the temperature inside the detection chamber 202, and a simulated wind component 6 for simulating wind speed in the detection chamber 202, wherein the simulated wind component 6 includes an air outlet piece 601 arranged in the detection chamber 202 and a blower 602 for supplying air to the air outlet piece 601, and air outlet slots 603 are evenly arranged on the side of the air outlet piece 601 facing the down jacket sample.
[0036] It should be noted that the humidity control unit and the temperature control unit belong to existing mature technologies, which are designed to control the humidity and temperature within a set range. They are commonly used in constant temperature and humidity incubators, ecological cabins and other scenarios. Therefore, the humidity control unit and the temperature control unit will not be described in detail here.
[0037] In this embodiment, the humidity control unit, the temperature control unit and the simulated wind component 6 are used to simulate the actual down jacket wearing environment in the detection chamber 202, thereby meeting the diverse requirements for down jacket light-irradiation heat storage and temperature-locking performance detection.
[0038] See also Figure 1 and Figure 5 In one embodiment of the present invention, slide grooves 9 are provided on both sides of the detection cavity 202, and sliders 10 and springs 12 are provided in the two slide grooves 9. T-shaped pieces 11 are provided on the two sliders 10, and the two groups of clamps 3 are respectively provided on the two T-shaped pieces 11. Two abutment rods 8 are provided on the cavity cover 4, and the ends of the two abutment rods 8 away from the cavity cover 4 are respectively abutted against the two T-shaped pieces 11. When the cavity cover 4 is closed, the two groups of clamps 3 are in the detection position, and when the cavity cover 4 is opened, the two groups of clamps 3 are in the preparation position.
[0039] In this embodiment, when the chamber cover 4 is located above the detection chamber 202 (open state), the two T-shaped pieces 11 are located at the upper position of the detection chamber 202 (with the spring 12 as the upper position of the detection chamber 202). Figure 1 For explanation), that is, the two sets of clamps 3 are in the preparation position, and after the down jacket sample is clamped, the cavity cover 4 moves down to cover the detection cavity 202 (closed state), and the two T-shaped pieces 11 are pressed into the lower middle position of the detection cavity 202 by the action of the resistance rod 8, that is, the two sets of clamps 3 are in the detection position.
[0040] See also Figure 1In one embodiment of the present invention, the box body 2 also includes a down collecting cavity 203, which is located below the detection cavity 202, and down suction holes 15 are evenly distributed between the down collecting cavity 203 and the detection cavity 202. The box body 2 is provided with a negative pressure fan 14 for forming a negative pressure in the down collecting cavity 203 to absorb the down.
[0041] In this embodiment, after the detection is completed, the down jacket sample moves up and separates from the monitoring part 13. Since the down jacket sample is punctured, down will run out and fall to the bottom of the detection cavity 202. After the down jacket sample is removed, the negative pressure fan 14 creates a negative pressure in the down collecting cavity 203 to absorb the fallen down, thereby quickly cleaning the detection cavity 202, and the absorbed down is concentrated in the down collecting cavity 203 for regular cleaning.
[0042] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
