Description

Technical Field

[0001] This utility model relates to the field of testing technology, and more specifically, it relates to a tester for the heating performance of steam eye masks and hot compresses. Background Technology

[0002] Steam eye masks or heating pads typically consist of non-woven fabric and a heating element. The heating element includes an outer bag and a filling section sealed within the outer bag, containing the heating element. The heating element's main components are iron powder, water, activated carbon, salt, and absorbent resin. The product utilizes the chemical reaction between the iron powder in the heating element and oxygen in the air to release heat and generate trace amounts of water vapor, thus achieving the effect of applying heat to the eyes. Heating performance is a key performance indicator for steam eye masks or heating pads, and accurately testing the heating performance of steam eye masks or heating pads has always been a challenge in the industry.

[0003] Currently, there is no unified standard for testing the temperature performance of products. FZ / T08007-2024 Disposable Steam Eye Masks, QB / T 4903-2016 Heat Patches, and YY 0060-2018 Fully Automatic Heat Compress Patches (Bags) specify different working flow rates, working temperatures, and sample fixing methods for the heating performance testers. QB / T 4903-2016 specifies a working flow rate of 2-4 L / min, while some standards specify a working flow rate of 10-14 L / min.

[0004] The applicant filed a Chinese utility model patent (publication number CN 221174463U) on August 24, 2023, disclosing a temperature performance testing device for a steam-heated eye mask. The device comprises a heating element and a thermometer. The thermometer includes a temperature gauge and a temperature probe connected via a connecting cable. The heating element includes a heater and a circulating constant-temperature water bath. A layer of PP plastic sheet is completely adhered to one side of the heater. Two layers of cotton gauze are laid and fixed to one side of the PP plastic sheet to form a test fabric surface. The cotton gauze is completely adhered to the PP plastic sheet surface without gaps. The temperature of the test fabric surface is controlled at 32℃±1℃. The eye-touching side of the steam-heated eye mask sample is fixed to the test fabric surface, ensuring its heating center point is aligned with the temperature probe. This technical solution proposes a temperature performance testing device with higher temperature detection accuracy.

[0005] However, this technical solution is a single-station testing method with low testing efficiency; moreover, each station has only one flow rate, which cannot control and meet the testing requirements of adjustable high and low flow rates. One device cannot simultaneously meet the testing requirements of different standards, and the instrument control conditions are limited, so it can only be used for testing steam hot compress eye masks, which needs to be improved.

A test window (not shown in the figure) is opened on the gauze silicone plate 266. Preferably, there are two test windows, which are located near both ends of the gauze silicone plate 266 and are symmetrically arranged.

[0057] The main frame 1 has three windows (not shown in the figure) that correspond to the test surfaces on the three test modules. When the test modules are installed on the main frame 1 in the preset positions, the test cloth surfaces on the three test modules are located at the three windows of the main frame 1 respectively.

[0058] like Figure 9-10 As shown, and in combination Figure 1The heater test chamber 26 also includes a sample cover 268 for pressing the sample. The sample cover 268 includes a frame body 2681 and a handle 2682. The handle 2682 is located on the outer surface of the frame body 2681. The frame body 2681 has two symmetrically arranged test windows corresponding to the gauze silicone plate 266. The frame body 2681 is detachably fixed to the window on the front of the main frame 1 by a clamping component, so that the inner surface of the frame body 2681 is pressed against the gauze silicone plate 266 and faces the gauze 265. In use, after the test sample is placed flat on the test cloth, the sample cover 268 is placed on the test sample and pressed down, so that the test sample is pressed and fixed between the test cloth and the sample cover 268 for testing. The clamping component can be a clamp or a fixture, etc., and there are no restrictions.

[0059] Back Figure 2-3 The balancing gas pipeline system 8 includes several balancing gas pipeline branches 81 and a main exhaust port 82. One end of each balancing gas pipeline branch 81 is connected to the balancing gas hole of the heating constant temperature water tank 25 on each test module, and the other end is connected to the main exhaust port 82. The balancing gas pipeline system 8 is used to balance the pressure of the overall test system, ensure smooth drainage, and ensure stable operation of the equipment.

[0061] The temperature position detection and adjustment system 9 includes a temperature instrument 91 and a temperature detector. The temperature detector includes a temperature probe 92 and a connecting wire 93. The temperature probe 92 is connected to the temperature instrument 91 via the connecting wire 93. The temperature probe 92 extends into and is fixed on the test cloth surface.

[0062] The air cooling system 10 is installed on the side wall of the main frame 1. In one possible embodiment, the air cooling system 10 includes several cooling fans (not shown in the figure) installed on the side wall of the main frame 1, which use forced ventilation to help dissipate heat and achieve a cooling effect.

[0063] The monitoring system 11 is installed on the front of the main frame 1. The monitoring system 11 can monitor and record the temperature of the instrument in real time.

[0064] The control system 12 is used for automatic control of the testing instrument. The control system 12 is electrically connected to the main testing system, water pump 5, balance air pipeline system 8, temperature and position detection and adjustment system 9, air cooling system 10, monitoring system 11, and power switch 13. As prior art, the control system 12 can be implemented using a PLC controller, computer, microcontroller, or other control structures; this application does not impose any limitations on this.

[0065] In addition, casters (not shown in the figure) are provided at the bottom of the main frame 1 to facilitate the movement of the tester.

[0066] When using the testing instrument of this utility model: First, the control system 12 controls the water pump 5 to work. External water enters from the main water inlet 3 and enters the heating constant temperature water tank 25 through the main water inlet pipeline system 4. The heating constant temperature water tank 25 works to reach a constant temperature state. The constant temperature water forms a circulating water circuit with the heater test box 26 through the working circuit 27. During the process, water can be drained out through the overflow pipe 28 and the main drainage pipe system 7 to ensure water circulation. This controls the temperature of the test cloth surface at 32℃±1℃. Then, according to the number of samples to be tested, the corresponding number of temperature probes 92 can be fixed in parallel on each test cloth surface of the three sets of test modules. The heating part of the steam eye mask or hot compress is placed on the test cloth surface and its heating center is aligned with the temperature probe 92. It is then pressed and fixed by the sample pressure cover 268. The thermometer 255 collects the highest temperature and heating time of the sample during the heating process. The three test modules on the tester can be flexibly applied according to the number of samples to be tested, and up to three testing stations can be tested simultaneously. It can meet the different testing requirements of FZ / T 08007-2024 disposable steam eye masks, T / CNTAC 192-2023 disposable steam eye masks, QB / T 4903-2016 heat patches, and YY0060-2018 fully automatic heat compress patches (bags) standards. The entire testing process is fully automated by the control system 12, reducing manual intervention and greatly improving testing efficiency.
