Description

Technical Field

[0001] This utility model relates to the field of humidity card testing technology, specifically a humidity card testing device. Background Technology

[0002] Regarding humidity regulation, most existing devices struggle to achieve precise and flexible humidity control. Some devices employ a single humidification or drying method, such as simply spraying water mist into the test space to increase humidity. This approach not only fails to stabilize humidity within a specific range but also results in excessively rapid humidity increases, making it impossible to simulate different humidity gradients. In terms of drying, some devices suffer from inconvenient desiccant replacement, leading to a gradual weakening of the drying effect and difficulty in maintaining a stable low-humidity environment. This results in significant errors in test results, failing to meet the requirements for comprehensive and accurate performance testing of humidity cards. Therefore, those skilled in the art have provided a humidity card testing device to address the problems mentioned in the background. Utility Model Content

[0003] The purpose of this invention is to provide a humidity card testing device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A humidity card testing device includes a sealing cover and a humidification component disposed on the sealing cover. The humidification component includes a first threaded cap, a first threaded retaining ring, an absorbent sponge, and a sponge holder. The sponge holder is fixedly connected to the lower surface of the sealing cover, and an absorbent sponge is disposed on the sponge holder. The first threaded retaining ring is fixedly connected to the upper end of the sealing cover, and the first threaded cap is threadedly connected to the surface of the first threaded retaining ring. A detection component is disposed on the lower surface of the sealing cover, and a drying component for reducing humidity is disposed on the tank assembly.

[0005] Furthermore, the detection component includes an upper tank, a lower tank, and an isolation plate. The upper tank is provided on the lower surface of the sealing cover, and the lower tank is fixedly connected to the lower end of the upper tank. An isolation plate is provided on the inner side wall of the lower tank, and a set of evenly distributed vent holes are provided on the isolation plate.

[0006] Furthermore, the detection component also includes a humidity display and a humidity test card. The internal spaces of the upper and lower tanks are interconnected and separated into an upper chamber and a lower chamber by a partition plate.

[0007] Furthermore, a humidity display and a humidity test card are provided on the upper surface of the isolation plate, and the humidity display and humidity test card are placed in the upper chamber. A desiccant for drying air is provided in the lower tank, and the desiccant is placed in the lower chamber.

[0008] Furthermore, the detection component also includes a rubber sealing ring and a snap-fit ​​ring. The snap-fit ​​ring is fixedly connected to the lower surface of the sealing cover, and the rubber sealing ring is fixedly connected to the surface of the snap-fit ​​ring, with the surface of the rubber sealing ring abutting against the inner side wall of the upper tank.

[0009] Furthermore, the drying assembly includes a second threaded retaining ring and a second threaded cap. The second threaded retaining ring is fixedly connected to the inner surface of the lower tank and is in communication with the lower chamber. The second threaded retaining ring is connected to the second threaded cap by threads.

[0010] Furthermore, the drying assembly also includes a filter screen, and the filter screen is fixedly connected inside the second threaded retainer. The second threaded retainer forms a space for storing desiccant inside through the filter screen and the second threaded retainer.

[0011] By adopting the above technical solution Compared with the prior art, the beneficial effects of this utility model are: When it is necessary to increase the humidity inside the tank, simply open the first threaded cap to directly add water into the sponge without disassembling the entire sealing cap, thus preventing external environmental interference with the experiment. The operation is simple and quick, and water can be replenished in time to ensure that the humidity inside the tank remains within a certain range, providing a stable humid environment for humidity testing. The humidification component facilitates the installation and replacement of the absorbent sponge. When the absorbent sponge's water absorption capacity decreases or it needs cleaning, the first threaded cap can be removed to maintain the absorbent sponge and ensure the continuous effectiveness of the humidification function. The sealed structure ensures that moisture is not easily lost during humidification, further improving the stability of humidity control. The upper and lower tanks are separated into an upper chamber and a lower chamber by a partition plate. Ventilation holes on the partition plate ensure airflow between the upper and lower chambers, allowing the humidity display and humidity test card to accurately sense the humidity of the test environment. The rubber sealing ring and snap-fit ​​ring enhance the sealing performance between the detection components and the sealing cover, preventing external environmental interference with the test results. Furthermore, placing the desiccant in the lower chamber effectively dries the air inside the tank during initial experiments, preventing humid air from affecting the test and further improving the accuracy of the detection. The design of the second threaded retaining ring, the second threaded cap, and the filter screen of the drying component creates a space for storing desiccant within the second threaded retaining ring. The filter screen prevents the desiccant from scattering. When the desiccant becomes saturated with moisture or needs to be added, the desiccant can be easily replaced simply by unscrewing the second threaded cap. This ensures that the drying component continues to function, maintains a stable internal humidity environment, extends the service life of the humidity gauge testing device, and reduces operating costs.

[0014] Please see Figures 1-4This utility model provides an embodiment of a humidity card testing device, including a sealing cover 1 and a humidifying component disposed on the sealing cover 1. The humidifying component includes a first threaded cap 4, a first threaded retaining ring 10, an absorbent sponge 11, and a sponge fixing frame 12. The sponge fixing frame 12 is fixedly connected to the lower surface of the sealing cover 1, and the absorbent sponge 11 is disposed on the sponge fixing frame 12. The first threaded retaining ring 10 is fixedly connected to the upper end of the sealing cover 1, and the first threaded cap 4 is threadedly connected to the surface of the first threaded retaining ring 10. A detection component is disposed on the lower surface of the sealing cover 1, and a drying component for reducing humidity is disposed on the tank assembly. The sealing cover 1 is made of glass and manufactured using a precision glass processing technology. The container is formed into a single unit, and its lower surface is also fixedly connected to a sponge holder 12 using glass processing technology. The sponge holder 12 is a glass frame structure, and its size is precisely matched to the size of the water-absorbing sponge 11 to ensure that the water-absorbing sponge 11 is placed stably. The holder has through grooves on both sides, allowing the moisture inside the sponge to evaporate into the container. The upper end of the sealing cap 1 is fixedly connected to the first threaded retaining ring 10 by glass hot bending or mechanical processing. The surface of the first threaded retaining ring 10 has external threads, and the first threaded cap 4 is also made of glass with matching internal threads on its inner surface. Through the threaded connection of the two, the water-absorbing sponge 11 is sealed and protected. The sealing structure of the glass material can effectively prevent moisture from evaporating outward.

[0015] In this embodiment, the detection assembly includes an upper tank 2, a lower tank 3, and an isolation plate 6. The upper tank 2 is disposed on the lower surface of the sealing cap 1, and the lower tank 3 is fixedly connected to the lower end of the upper tank 2. The isolation plate 6 is disposed on the inner side wall of the lower tank 3, and a set of evenly distributed vent holes 16 are opened on the isolation plate 6. The detection assembly also includes a humidity display 7 and a humidity test card 8. The internal spaces of the upper tank 2 and the lower tank 3 are interconnected and separated into an upper chamber 5 and a lower chamber 9 by the isolation plate 6. The humidity display 7 and the humidity test card 8 are disposed on the upper surface of the isolation plate 6, and the humidity display 7 and the humidity test card 8 are placed in the upper chamber. The lower tank 3 contains a desiccant for drying air, and this desiccant is placed in the lower chamber 9. The detection assembly also includes a rubber sealing ring 17 and a snap-fit ​​ring 18. The snap-fit ​​ring 18 is fixedly connected to the lower surface of the sealing cover 1, and the rubber sealing ring 17 is fixedly connected to the surface of the snap-fit ​​ring 18. The surface of the rubber sealing ring 17 abuts against the inner wall of the upper tank 2. The snap-fit ​​ring 18, made of glass, is fixedly connected to the lower surface of the sealing cover 1. The snap-fit ​​ring 18 and the sealing cover 1 can be connected by glass welding or a special glass adhesive. The rubber sealing ring 17 is fixedly connected to the surface of the snap-fit ​​ring 18 through a glass surface treatment process. Both the upper tank 2 and the lower tank 3 are made of glass. The top of the upper tank 2 is open, and the inner diameter of the opening is adapted to the outer diameter of the snap-fit ​​ring 18. The upper tank 2 is fitted over the snap-fit ​​ring 18, so that the rubber sealing ring 17 tightly abuts against the inner wall of the upper tank 2, ensuring the sealing of the connection. The outer diameter of the lower end of the upper tank 2 is larger than the inner diameter of the opening of the lower tank 3, so that when the upper tank 2 and the lower tank 3 are connected, they form an annular platform. The isolation plate 6 is made of iron, and its shape and size are adapted to the annular platform. It can be freely placed on the annular platform without the need for additional fixing structures and can be easily removed at any time. A set of evenly distributed vent holes 16 are made on the isolation plate 6 by stamping or cutting. A humidity display 7 and a humidity test card 8 are placed on the upper surface of the isolation plate 6. The lower tank 3 contains a desiccant, which can be a common moisture-absorbing material such as granular silica gel. The glass tank makes it easy to observe the state of the desiccant.

[0016] In this embodiment, the drying assembly includes a second threaded retaining ring 13 and a second threaded cap 14. The second threaded retaining ring 13 is fixedly connected to the inner surface of the lower tank 3 and is interconnected with the lower chamber 9. The second threaded retaining ring 13 is threadedly connected to the second threaded cap 14. The drying assembly also includes a filter screen 15. The filter screen 15 is fixedly connected inside the second threaded retaining ring 13, and the second threaded retaining ring 13 forms a space for storing desiccant inside through the filter screen 15 and the second threaded retaining ring 13. The second threaded retaining ring 13 is fixedly connected to the inner surface of the lower tank 3 through a glass processing process. The second threaded retaining ring 13 is interconnected with the lower chamber 9 and has external threads on its surface. The second threaded cap 14 is made of glass and has matching internal threads on its inner surface. The filter screen 15 is fixedly connected inside the second threaded retainer 13 by glass bonding or special fixing process. The mesh size of the filter screen 15 is designed to prevent desiccant particles from leaking out while ensuring smooth airflow, thus forming a space for storing desiccant inside the second threaded retainer 13. The glass material makes the structure and internal condition of the drying component clear at a glance.

[0017] First, open the second threaded cap 14. Place sufficient desiccant in the space formed by the second threaded retainer 13 and the filter screen 15, as well as in the lower chamber 9. Then, tighten the second threaded cap 14. The desiccant continuously absorbs moisture from the tank. Monitor the internal humidity of the tank in real time using the humidity display 7 until the internal humidity reaches the dry peak value, providing an initial drying environment for subsequent humidity adjustment. Place the humidity test card 8 and humidity display 7 at the designated positions on the upper surface of the isolation plate 6. The placement of the internal components can be clearly seen through the glass tank. Because the platform formed at the connection between the lower tank 3 and the upper tank 2 stably supports the isolation plate 6, the stability of the humidity display 7 and humidity test card 8 is ensured. Once the internal humidity reaches the dry peak value, begin gradually adjusting the humidity. Without disassembling the entire sealing cap 1, directly open the first threaded cap 4. Use a dropper or other water-adding tool to add a small amount of water to the absorbent sponge 11. After adding water, tighten the first threaded cap 4. Wait for a period of time to allow the water to evaporate fully, and observe the changes in internal humidity through the humidity display 7. If the target humidity is not reached, the first threaded cap 4 can be opened again, and an appropriate amount of water can be added to the absorbent sponge 11. This process can be repeated to gradually unlock different humidity conditions until the desired humidity environment is achieved, providing suitable humid conditions for humidity testing. The glass sealing cap 1 and humidification component allow for direct observation of the absorbent sponge 11's water absorption and evaporation. After the target humidity is reached, the humid air inside the tank circulates between the upper and lower chambers 9 through the vent holes 16 on the isolation plate 6. The humidity display 7 displays the humidity value of the upper chamber 5 in real time. The humidity test card 8 changes color or undergoes other physicochemical changes depending on the humidity environment it comes into contact with. The glass tank allows testers to observe the changes in the humidity test card 8 from different angles and clearly read the values ​​on the humidity display 7 to obtain the humidity data inside the tank. When it is necessary to test the effect of the test card under lower humidity conditions, i.e., after reaching the humidity peak value, the second threaded cap 14 can be opened, and the desiccant can be added or replaced in the drying component. Then, the second threaded cap 14 can be tightened. The newly added desiccant begins to absorb excess moisture inside the can, and the humidity display 7 monitors the changes in humidity inside the can in real time until a new, lower humidity condition is reached. At this point, the changes in the humidity test card 8 are observed again to obtain the performance data of the test card at different stages of humidity decrease, thus completing a comprehensive test of the test card's performance under different humidity conditions.
