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 patches (also called "heating patches" or "warming patches") are typically composed of non-woven fabric and a heating element. The heating element includes an outer bag and a filling section sealed in the middle of the outer bag, containing the heating element. The heating element's main components are iron powder, water, activated carbon, salt, and water-absorbing resin. The product utilizes the chemical reaction between the iron powder in the heating element and oxygen in the air to release heat, thereby achieving a heat therapy effect. Heating performance is a key performance indicator for steam eye masks or heating patches, and accurately testing the heating performance of steam eye masks or heating patches has always been a challenge in the industry.

[0003] Standards FZ / T 08007-2024 "Disposable Steam Eye Masks", QB / T 4903-2016 "Heat Patches", and YY 0060-2018 "Medical Hot Compress Patches (Bags)" specify different working flow rates, working temperatures, and sample fixing methods for heating performance testers. QB / T4903-2016 specifies a working flow rate of 2-4 L / min, while some standards specify a working flow rate of 10-14 L / min. The applicant filed a Chinese utility model patent application (application number 202423098635.8) on November 16, 2024, disclosing a heating performance tester for steam eye masks and hot compress patches. This instrument has three testing stations, enabling simultaneous testing at all three stations, and the working flow rate is switchable to meet different testing requirements simultaneously.

[0004] QB / T 4903-2025 "Disposable Heating Patches (Pouches)" replaces QB / T 4903-2016 "Heat Patches" and sets new requirements for the working flow rate of heating performance testers. QB / T 4903-2025 specifies a working flow rate of (12±2) L / min. FZ / T 08007-2024 "Disposable Steam Eye Masks," QB / T 4903-2025 "Disposable Heating Patches (Pouches)," and YY 0060-2018 "Medical Hot Compress Patches (Pouches)" all specify the same working flow rate for heating performance testers, eliminating the need for separate flow rate control at each testing station on the testing equipment. Therefore, a new testing device is needed to adapt to the new standard.

[0005] The steam eye mask and heat therapy patch heating performance tester disclosed in application number 202423098635.8 requires each test station to be equipped with an independent heating water tank and each individual test device to be equipped with a separate control valve in order to achieve different flow rates at different work stations. This results in as many as 15 control valves in the entire test equipment, which greatly increases the cost of the test equipment and needs to be improved. Utility Model Content

[0006] To address this problem in practical applications, the purpose of this utility model is to propose a steam eye mask and heat therapy patch heating performance tester, the specific solution of which is as follows:

[0007] A steam eye mask and heat therapy patch heating performance tester includes a main frame and a main water inlet, a main water inlet pipe, a water pump, a constant temperature heating water tank, at least one test station, a main water outlet, a main drainage pipe, and a control system, all mounted on the main frame.

[0008] The main water inlet is connected to the main water inlet pipe via the water pump and the main water inlet solenoid valve, and the other end of the main water inlet pipe is connected to the water inlet of the constant temperature heating water tank.

[0009] The outlet of the constant temperature heating water tank is connected to the return outlet of the constant temperature heating water tank via a working pipeline, at least one test station, and a return water pipeline to form a circulation loop.

[0010] One end of the main drain pipe is connected to the working pipe and / or the overflow port of the constant temperature heating water tank, and the other end of the main drain pipe is connected to the main water outlet. A drain solenoid valve is installed between the main drain pipe and the working pipe.

[0011] Furthermore, the working pipeline includes a main pipeline and branch pipelines. One end of the main pipeline is connected to the outlet of the constant temperature heating water tank, and the other end is connected to at least one branch pipeline. Each branch pipeline is connected to a test station, and each branch pipeline is equipped with a circulating speed regulating water pump and a flow meter.

[0012] Furthermore, the constant temperature heating water tank is equipped with a thermometer and a heater.

[0013] Furthermore, each of the test stations includes a heater test chamber and a temperature position detection and adjustment system installed on one side surface of the heater test chamber.

[0014] Furthermore, the test window on the heater test chamber is provided with at least two elastic bands, which are used to fix the sample.

[0015] Furthermore, one end of the sample cap on the thermostat test chamber is hinged to the main frame, and the other end is fixed to the main frame by a rotating fastener, which is used to press the sample.

[0016] Furthermore, one side surface of the sample cap is provided with a velvet cloth, which is pressed by a pressure ring around its circumference and fixed by fasteners.

[0017] Furthermore, five testing stations are provided within the main frame.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] (1) The present invention integrates five testing stations into a single unit and uses a uniform working flow rate for synchronous testing, effectively meeting the technical requirements of the new standard. Compared with the traditional three-station testing instrument, this application not only improves the testing speed and shortens the testing time, but also simplifies the system structure. It only requires two solenoid valves for centralized control, and a constant temperature heating water tank provides a constant temperature environment for all five stations, significantly reducing the number of control valves and constant temperature heating water tanks, thereby greatly reducing the overall cost of the instrument.

[0020] (2) By using elastic bands to fix the sample, the traditional adhesive tape method is replaced, making the operation simpler and faster, and overcoming the problems of excessive tape use, easy tape residue, poor adhesion or damage to the sample. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0030] like Figure 1-4 As shown, a steam eye mask and heat therapy patch heating performance tester includes a main frame 1 and five test stations 2 disposed on the main frame 1. The five test stations 2 are arranged on a mounting plate (not shown in the figure) inside the main frame 1. The arrangement of the five test stations 2 can be determined according to actual needs. In this embodiment, the mounting plate has three layers, with one test station 2 located on the first layer, and the remaining four test stations 2 arranged in pairs on the second and third layers, respectively. The main frame 1 has five windows (not shown in the figure) corresponding to the test surfaces of the five test stations 2. When the test module is installed on the main frame 1 in a preset position, the test cloth surfaces of the five test stations 2 are exactly located at the five windows of the main frame 1.

[0031] The tester also includes a main water inlet 3, a main water inlet pipe 4, a water pump 5, a constant temperature heating water tank 6, a main water outlet 7, and a main drainage pipe 8, all located on the main frame 1.

[0032] Combination Figure 5 The main water inlet 3 is connected to the main water inlet pipeline 4 via the water pump 5 and the main water inlet solenoid valve 9. The other end of the main water inlet pipeline 4 is connected to the water inlet of the constant temperature heating water tank 6. The water pump 5 is an inlet diaphragm pump.

[0033] The outlet of the constant temperature heating water tank 6 is connected to the return water port of the constant temperature heating water tank 6 via the working pipeline 10, five test stations 2, and the return water pipeline 11, forming a circulation loop. Specifically, the constant temperature heating water tank 6 has one outlet; the working pipeline 10 includes a main pipeline 101 and branch pipelines 102. One end of the main pipeline 101 is connected to the outlet of the constant temperature heating water tank 6, and the other end is connected to five branch pipelines 102. Each branch pipeline 102 is connected to one test station 2; the constant temperature heating water tank 6 has five return water ports, and each test station 2 is connected to one return water port of the constant temperature heating water tank 6 via a return water pipeline 11.

[0034] Each branch pipe 102 is equipped with a circulating speed-regulating water pump 12 and a flow meter 13. The circulating speed-regulating water pump 12 is used to automatically adjust the speed to match the water volume with the heat load, thereby saving energy. The flow meter 13 is used to monitor the fluid flow rate in real time.

[0035] The constant temperature heating water tank 6 is equipped with a thermometer 14 and a heater 15. The heater 15 is used to heat the liquid in the constant temperature heating water tank 6. The thermometer is used to monitor the temperature of the liquid in the constant temperature heating water tank 6 in real time.

[0036] One end of the main drainage pipe 8 is connected to the main outlet 7, and the other end has two branches. One branch is connected to the main pipe 101 of the working pipe 10, and the other branch is connected to the overflow port 16 of the constant temperature heating water tank 6. The overflow port 16 is designed to prevent the water level in the constant temperature heating water tank 6 from overflowing due to excessively high water levels.

[0037] A solenoid valve 17 is installed between the main drainage pipe 8 and the main pipe 101.

[0038] Each test station 2 includes a heater test chamber and a temperature position detection and adjustment system installed on one side surface of the heater test chamber.

[0039] To make the operation simpler and faster, go back to Figure 1 The test window of the heater test chamber is equipped with at least two elastic bands 19 for fixing the sample, replacing the existing adhesive tape method. Preferably, there are three elastic bands 19. The elastic bands 19 can be made of rubber or similar materials. The elastic bands 19 overcome the problems of excessive tape use, tape residue, poor adhesion, or damage to the sample.

[0040] To further improve ease of operation, combined with Figure 1 and Figure 6 One end of the sample cap 18 on the thermostat test chamber is hinged to the main frame 1 via a hinge 20, and the other end is fixed to the main frame 1 via a rotating fastener 21, which facilitates quick clamping or releasing of the sample. The rotating fastener 21 can be a rotating buckle, an eccentric wheel, etc., and there are no restrictions on its use.

[0041] In addition, see Figure 7 In existing specimen caps 18, the felt 22 is fixed to the cap body with screws, which can easily lead to the felt 22 detaching. This embodiment addresses this issue by providing a new feature: as shown in the figure, a felt 22 is provided on one side of the specimen cap 18. The felt 22 is pressed together by a pressure ring 23 that surrounds it and secured with fasteners. Screws can be used as fasteners. Compared to existing technology, the pressure ring 23 provides more comprehensive compression of the felt 22, reducing the likelihood of the felt 22 detaching from the specimen cap 18.

[0042] Furthermore, the specific structure of the heater test chamber and temperature position detection and adjustment system in this application can be found in the chamber design of the "A Steam Eye Mask and Heating Patch Heating Performance Tester" disclosed in patent application number 202423098635.8. Since this application does not make substantial improvements to the above-mentioned parts, its specific structure and principle will not be elaborated here.

[0043] Finally, it should be noted that the testing instrument in this application also includes conventional configurations for maintaining instrument stability, such as a balancing air pipeline connected to the constant temperature heating water tank for balancing the test pressure, an air cooling system for cooling the instrument, a control system for automatically controlling the testing instrument, a monitoring system for real-time monitoring and recording of the instrument temperature, a power switch, and casters mounted on the bottom of the testing instrument for easy movement. Since this application does not involve improvements to these parts, their specific structures and principles will not be elaborated here.

[0044] The specific implementation principle of this utility model is as follows: At the start of the test, the water pump 5 starts, the inlet solenoid valve opens, and external water is injected into the system through the main inlet 3. The water flows through the main inlet pipe 4 into the constant temperature heating water tank 6, where it is heated and maintained at a constant temperature. The constant temperature water is then evenly distributed to the five test stations 2 through the working pipe 10 and returns to the water tank through the return water pipe 11, thus forming a complete circulating water circuit to ensure consistent flow at each station. To maintain system stability, the overflow port 16 of the constant temperature heating water tank 6 continues to operate to discharge excess water; at the same time, the drain solenoid valve 17 can be opened according to the command to drain water through the main drain pipe 8. This controls the temperature of the test station 2 at (32±1)℃ or (35±1)℃, and performance testing can then be carried out at the test station.

[0045] The tester can perform simultaneous testing at five testing stations, and the working flow rate of the five testing stations is the same. The working flow rate can simultaneously meet the testing requirements of the standards FZ / T 08007-2024 "Disposable Steam Eye Masks", QB / T 4903-2025 "Disposable Heating Patches (Bags)" and YY 0060-2018 "Fully Automatic Heating Patches (Bags)".

[0046] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
