Abstract
Description
Technical Field
[0001] This utility model relates to the field of steam compress eye mask testing technology, and more specifically, it relates to an automatic steam volume tester for steam compress eye masks. Background Technology
[0002] Steam-heated eye masks typically consist of a non-woven fabric eye mask body, a pair of heating elements symmetrically positioned on both sides of the eye mask body, and a pair of ear loops. The heating elements are located in the middle of both sides of the eye mask body. Each heating element includes an outer bag and a filling part sealed in the middle of the outer bag and filled with the heating elements. The heating elements are mainly composed of 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 and generate a small amount of water vapor, thereby achieving the effect of heat compressing the eyes. The amount of steam generated is one of the main performance indicators of steam-heated eye mask products. Many companies claim that their products generate a lot of water vapor during the heating process, but accurate and efficient detection of the amount of steam generated by steam-heated eye masks has always been a challenge in the industry, especially for the amount of water vapor generated on the side of the steam-heated eye mask that is in contact with the face. Current detection devices and methods still have certain shortcomings.
[0003] For example, Chinese invention patent CN115979875A discloses a device and method for detecting the amount of water vapor generated by a steam-heated eye mask. The device includes a sealed box, a sample fixing module, a temperature-controlled heating plate module, and a temperature and humidity monitoring module disposed within the sealed box. Using the above-mentioned detection device, the eye mask is fixed to the sample fixing module with the contact side facing upwards. The error of the detection device is calibrated by the temperature-controlled heating plate module and the temperature and humidity monitoring module to determine the detection calibration coefficient of the device. The detection device of this technical solution has a simple structure and high detection accuracy.
[0004] However, this technical solution requires manual operation and calculation during the testing process. For example, when checking the sealing performance of the sealed box, it is necessary to manually operate the vacuum pump and manually monitor whether there is any change in the vacuum degree inside the sealed box to determine whether the sealing performance of the sealed box is good. This not only increases the workload of the operators, but also improper human operation may lead to errors in the testing process, which seriously affects the testing efficiency.

[0038] The front panel of the lower enclosed space is the door 2. The door 2 is connected to the sealed box 1 by a hinge. The door 2 is equipped with a door lock 21, which is used to lock the door 2 to the sealed box 1.
[0039] The upper plate of the upper enclosing space is the upper cover 11. The upper cover 11 is connected to the sealed box 1 by a hinge. The upper cover 11 is provided with a locking mechanism 12, which is used to lock the upper cover 11 to the sealed box 1.
[0040] It should be noted that both the door lock 21 and the locking mechanism 12 can adopt door lock structures disclosed in the prior art. The door lock structure is not an improvement of this application and will not be described in detail here.

[0042] The sample holder 4 is also located on the bottom panel within the lower enclosed space of the sealed box 1. The sample holder 4 is used to fix the steam hot compress eye mask sample. The sample holder 4 can be the sample fixing module disclosed in the invention patent with patent publication number CN115979875A and patent name "A device and method for detecting the amount of water vapor generated by a steam hot compress eye mask", which will not be described again in this application.
[0043] The temperature and humidity detection mechanism 5 includes a temperature and humidity sensor module 51 housed within a sealed enclosure 1. The temperature and humidity sensor module 51 is electrically connected to the control center 71. The temperature and humidity sensor module 51 is installed within the upper enclosed space, with its detection end penetrating the upper plate shared by the two enclosed spaces until it enters the lower enclosed space, aligning with the sample holder 4. The temperature and humidity detection mechanism 5 is used to detect the temperature and humidity within the sealed enclosure 1.
[0044] The airtightness detection module 6 is used to automatically detect the airtightness of the sealed box. It is located in the upper enclosed space of the sealed box 1 and includes a vacuum pump 61, pipelines, pipeline solenoid valves, vacuum inlet 67, airtightness detection port 68, and vacuum controller 73. The pipelines include a vacuum pipeline 62 and a ventilation pipeline 63, and the pipeline solenoid valves include a vacuum pipeline solenoid valve 64 and a ventilation pipeline solenoid valve 65.
[0045] Vacuum pump 61 is connected to vacuum inlet 67 via vacuum line 62, and vacuum line solenoid valve 64 is installed on vacuum line 62; vacuum line 62 and ventilation line 63 are connected to vacuum inlet 67 via tee pipe 66, and ventilation line solenoid valve 65 is installed on ventilation line 63; vacuum inlet 67 is connected to airtightness detection port 68, which is located on a panel shared by two enclosed spaces in sealed housing 1; vacuum controller 73 is electrically connected to vacuum pump 61 and pipeline solenoid valve, and is used to control the automated operation of airtightness detection module.

[0047] Furthermore, to ensure the vacuum level, the vacuum inlet 67 and the airtightness detection inlet are sealed together, which can be achieved by using sealing rubber or other methods.
[0048] The power module 8 can be powered by an external power source and / or by a battery. The power interface 81 provided on the sealed enclosure 1 is designed to meet the requirements of an external power source.

[0053] In addition, a door lock sensor 22 is provided on the sealed enclosure 1 at a location corresponding to the door 2. The door lock sensor 22 can be used to monitor the opening and closing status of the door 2 in real time and issue alarms and notifications in abnormal situations to ensure the airtightness of the sealed enclosure 1 during the detection process and avoid the problem of reduced detection accuracy due to insufficient sealing of the door 2.

[0056] The automatic steam volume tester for the steam-heated eye mask provided in this embodiment is used for the following detection method:
[0057] (1) Check the airtightness of the enclosure by closing the door 2 of the sealed enclosure 1, the control system 7 automatically controls the opening of the vacuum pipeline solenoid valve 64, and at the same time closes the ventilation pipeline solenoid valve 65, starts the vacuum pump 61, and extracts the air from the vacuum pipeline 62, the vacuum inlet 67 and the lower enclosed space of the sealed enclosure 1, so that the lower enclosed space forms a negative pressure state until the vacuum degree is extracted to -0.02MPa to -0.05MPa. Then close the vacuum pipeline solenoid valve 64 to maintain the pressure. After that, the pressure sensor 69 monitors whether there is any change in the vacuum degree inside the sealed enclosure 1. If there is no change in the vacuum degree within 20 minutes, it can be considered that the sealing performance inside the sealed enclosure 1 is good. The control system 7 outputs a signal and displays it on the monitoring screen 9.
[0058] Then, when needed, keep the vacuum line solenoid valve 64 closed and open the ventilation line solenoid valve 65 to allow the gas inside the sealed chamber 1 to be discharged to the external environment. If water vapor is generated by the sample during the test, causing moisture to be present inside the sealed chamber 1, the moisture can be discharged through the ventilation line 63.
[0059] (2) Detection of sample steam volume: The method of steam volume detection can be the detection method disclosed in the invention patent with patent publication number CN115979875A and patent name "A device and method for detecting the amount of water vapor generated by a steam hot compress eye mask". Unlike that patent, the detection process and results of this application are automatically controlled and calculated by the control system 7, without the need for human operation, which can reduce the number of human operation steps.
