Description

Technical fields:

[0001] This utility model relates to the field of humidity indication technology, specifically a waterproof humidity indicator valve with waterproof and humidity indication functions. It can be used on items that are sensitive to humidity changes and require timely control of humidity changes, such as power batteries and aerospace material packaging. It can be installed on items in enclosed spaces to isolate the external environment and indicate changes in humidity within the enclosed space. Background technology:

[0002] If leaks occur in the sealed packaging of aircraft engine materials, electronic equipment, power batteries, and other items during long-term transportation, the damage caused by moisture and water to the aircraft engine materials, electronic equipment, power batteries, etc. inside the packaging will not be reported in time, and effective measures will not be taken in time, resulting in greater losses.

[0003] Humidity indicator cards consist of colored rings containing a humidity indicator on cardstock. These rings change color when the corresponding humidity level is reached, indicating the humidity level through the color change of the humidity indicator within the ring. Humidity indicator cards are commonly used to monitor humidity changes within sealed packaging. For example, Chinese utility model patent application number 202420927942.3 discloses a foldable humidity indicator card, comprising: a humidity indicator card base and an upper reagent protective ring. The top of the humidity indicator card base has an array of upper reagent protective rings spaced apart, and the base has spaced bending grooves. A first connection sticker is fixedly connected to the first end of the base. The base is a rectangular cardboard structure. The inner side of the upper reagent protective ring is the inner reagent area, and the upper reagent protective ring surrounds the outer side of the inner reagent area. In use, the humidity indicator reagent in this inner reagent area comes into contact with air and reacts with moisture in the air, thus indicating the humidity.

[0004] However, the humidity indicator cards mentioned above can only be placed inside packaging bags / boxes to indicate the humidity inside. For packaging bags / boxes that cannot be seen inside (such as the sealed packaging boxes for items like aircraft engine materials, electronic equipment, and power batteries), the humidity indicator cards cannot provide humidity indication. If the humidity indicator cards are installed on the surface of the packaging bags / boxes, they cannot directly indicate the humidity inside, causing great inconvenience to users.

[0005] In view of the above, the inventors propose the following technical solution. Utility Model Content:

[0027] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0028] See Figure 1-9 As shown, a waterproof humidity indicator valve is characterized by comprising: a valve body 1, a humidity indicator card 2, a transparent component 3, an inner sealing ring 4, and fasteners 5.

[0029] The valve body 1 has a downward protruding mounting part 11 at its lower end for mounting with the mounting interface 70, and a stepped mounting groove 12 at its upper end. The humidity indicator card 2 changes color in response to ambient humidity, i.e., it changes color when exposed to moisture. This is a conventional product in the prior art. The humidity indicator card 2 is installed in the stepped mounting groove 12. The transparent part 3 is embedded in the stepped mounting groove 12 and covers the humidity indicator card 2. The transparent part 3 and the stepped mounting groove 12 are sealed together by an inner sealing ring 4, isolating the humidity indicator card 2 from the outside environment. The fastener 5 is fixed in the stepped mounting groove 12 and secures the transparent part 3 in the stepped mounting groove 12. The transparent part 3 is exposed outside the valve body 1 so that the humidity indicator card 2 can be viewed through the transparent part 3. That is, after the humidity indicator card 2 changes color when exposed to moisture, external users can directly view the color change of the humidity indicator card 2 through the transparent part 3 to know the humidity of the internal environment. In other words, the waterproof humidity indicator valve of this utility model is directly installed on the packaging interface or the user interface (collectively referred to as the installation interface) through the installation part 11 of the valve body 1. The humidity indicator card 2 installed inside the valve body 1 can indicate the humidity change of the internal environment in a timely manner through color change, and can be directly observed through the transparent part 3. It can keep track of the humidity change in the environment in a timely manner, so as to take certain measures to reduce the damage of moisture to materials or instruments and equipment. Furthermore, the transparent part 3 and the stepped installation groove 12 form a sealed assembly through the inner sealing ring 4, which isolates the humidity indicator card 2 from the outside world, effectively preventing external moisture from entering the internal environment and preventing external dust and water vapor from damaging the internal environment. That is, it is not affected by the external environment and achieves IP68 waterproof and moisture-proof function.

[0030] The valve body 1 is made of metal or plastic. The upper end of the valve body 1 is hexagonal, which facilitates the use of tools to screw the valve body 1.

[0031] The stepped mounting groove 12 includes a first groove 121 extending downward from the upper end of the valve body 1 and a second groove 122 extending downward from the bottom of the first groove 121 and penetrating the lower end face of the valve body 1. The inner diameter of the first groove 121 is larger than the inner diameter of the second groove 122, that is, the stepped mounting groove 12 is in the shape of an inverted convex character. The humidity indicator card 2 is installed at the bottom of the first groove 121. The inner sealing ring 4 is installed at the bottom of the first groove 121 and located around the humidity indicator card 2. The transparent part 3 is installed in the first groove 121 and pressed on the inner sealing ring 4. The fastener 5 is fixed in the first groove 121.

[0032] The bottom of the first groove 121 is also formed with a spacer strip 123, which divides the bottom of the first groove 121 into a first mounting position 101 and a second mounting position 102. The first mounting position 101 is connected to the second groove 122. The humidity indicator card 2 is installed in the first mounting position 101, and the inner sealing ring 4 is embedded in the second mounting position 102, so that the inner sealing ring 4 does not contact the humidity indicator card 2, but is separated by the spacer strip 123, so as to prevent damage to the humidity indicator card 2. The spacer strip 123 can also limit the humidity indicator card 2, so that the humidity indicator card 2 is positioned in the first mounting position 101.

[0033] The humidity indicator card 2 changes color in response to the humidity of the internal environment. Different humidity values ​​cause the indicator card to produce different colors, and there is a certain color development rule. For example, when the humidity of the internal environment is 50%RH, the humidity indicator card 2 with a humidity of 10% to 50% will change color to the corresponding color.

[0034] The specific structure of the humidity indicator card 2 is as follows: The humidity indicator card 2 is provided with at least one slot 21 that connects to the stepped mounting groove 12. That is, the color change area of ​​the humidity indicator card 2 is located on the upper surface (i.e. the side facing the transparent part 3) and is provided with a slot 21 that connects to the stepped mounting groove 12, thereby connecting to the internal environment (such as the internal environment of the product box or the internal environment of the packaging box). So that when the humidity in the internal environment reaches the humidity threshold at which the humidity indicator card 2 changes color, the humidity indicator card 2 will detect the color change and indicate the humidity of the internal environment.

[0035] The slot 21 has at least two of the following configuration methods:

[0036] The first type: the slot 21 is located outside the humidity indicator card 2, and the slot 21 forms a channel with the inner wall of the stepped mounting slot 12; for example... Figure 3As shown, the humidity indicator card 2 is triangular in shape, with three slots 21 arranged in a triangular pattern on its exterior, forming three channels with the inner wall of the stepped mounting groove 12; of course, the humidity indicator card 2 is linear in shape, with two slots 21 on its two sides, forming two channels with the inner wall of the stepped mounting groove 12; the humidity indicator card 2 can be triangular or other shaped, as long as slots 21 can be provided on its exterior.

[0037] The second type: The slot 21 is located in the middle of the humidity indicator card 2, and it can also connect to the stepped installation slot 12, which has a simpler structure.

[0038] Regardless of its shape or design, the humidity indicator card 2 is only required to make full contact with the internal environment and respond to the ambient humidity; there are no excessive restrictions.

[0039] The humidity thresholds at which the humidity indicator card changes color are: 10%RH, 20%RH, 30%RH, 40%RH, 50%RH, 60%RH, 70%RH, or 80%RH. Specifically, if a 20%RH humidity indicator card is used, the humidity indicator card will change color when the ambient humidity is ≥20%RH, but will not change color when the ambient humidity is <20%RH.

[0040] The transparent component 3 is a sheet of material such as glass, acrylic, or transparent composite fiberglass. It only needs to be able to see through, that is, the transparent component 3 has transparency and can observe the color of the humidity indicator card 2 inside from the outside, thereby judging the humidity of the internal environment.

[0041] The fastener 5 is ring-shaped and has an observation port 51 extending through its upper and lower ends, through which the humidity indicator card 2 is exposed. In other words, in actual use, the color change of the humidity indicator card 2 can be observed through the observation port 51 and the transparent part 3, thereby determining the humidity of the internal environment.

[0042] The fastener 5 can be assembled in at least the following two ways:

[0043] The first method involves embedding the fastener 5 in the stepped mounting groove 12 and fixing it in place by interference fit or snap fastener. This method is simple to assemble, but it is difficult to remove the fastener 5 from the stepped mounting groove 12 after installation.

[0044] The second type: The fastener 5 has an external thread on its exterior and an internal thread in the stepped mounting groove 12. The fastener 5 is screwed together with the internal thread in the stepped mounting groove 12 through its external thread, forming a detachable assembly. It is easy to install and can be quickly disassembled, thereby replacing the humidity indicator card 2. This makes the present invention reusable, more environmentally friendly and energy-saving, and improves market competitiveness.

[0045] The upper end of the mounting part 11 has an annular groove 111 extending from the outside inward. The inner side of the outer sealing ring 6 is pressed into the annular groove 111 from the outside inward to fix it to the upper end of the mounting part 11. The upper end of the outer sealing ring 6 is in contact with the lower end face of the valve body 1, which ensures that the outer sealing ring 6 is stably installed on the upper end of the mounting part 11 and is not easy to detach, thereby improving the stability of the assembly structure and improving product quality. In actual use, after the mounting part 11 is installed with the mounting interface 70, the outer sealing ring 6 contacts the outer sealing ring 6, thereby achieving the purpose of sealing assembly. In this embodiment, the mounting interface 70 is provided on the surface of the housing 7. The mounting interface 70 is provided with a screw hole, and the outer periphery of the mounting part 11 is provided with an external thread. It is screwed into the screw hole through the external thread to fix the valve body 1 to the mounting interface 70.

[0046] A sealing plug 8 is also embedded in the lower end of the stepped mounting groove 12, forming a sealed space 10 between the stepped mounting groove 12, the sealing plug 8, and the transparent part 3. The humidity indicator card 2 is placed in the sealed space 107. When not in use, the sealing plug 8 is embedded in the lower end of the stepped mounting groove 12, thus placing the humidity indicator card 2 in the sealed space 10, ensuring that the humidity indicator card 2 is not affected by the external environment, thereby ensuring the accuracy of the humidity indicator card 2. After the present invention is installed and fixed on the mounting interface 70 of the box body 7, the sealing plug 8 is pulled out relative to the valve body 1, so that the stepped mounting groove 12 communicates with the inner cavity of the box body 7.

[0047] In summary, the waterproof humidity indicator valve of this utility model is directly installed on the packaging interface or the user interface (collectively referred to as the installation interface) through the installation part 11 of the valve body 1. The humidity indicator card 2 installed inside the valve body 1 can indicate the humidity change of the internal environment in a timely manner through color change, and can be directly observed through the transparent part 3. This allows for timely monitoring of humidity changes in the environment, thereby enabling the taking of certain measures to reduce the damage of moisture to materials or instruments and equipment. Furthermore, the transparent part 3 and the stepped installation groove 12 form a sealed assembly through the inner sealing ring 4, which isolates the humidity indicator card 2 from the outside world, effectively preventing external moisture from entering the internal environment and preventing damage to the internal environment from external dust and water vapor. In other words, it is unaffected by the external environment and achieves IP68 waterproof and moisture-proof functions.

[0048] Of course, the above description is only a specific embodiment of the present utility model and is not intended to limit the scope of the present utility model. All equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model should be included in the scope of the claims of the present utility model.
