Description

Technical Field

[0001] This utility model relates to the field of dehumidification bag technology, and in particular to a car dehumidification bag. Background Technology

[0002] With the increasing frequency of car use, controlling the humidity inside the vehicle has become a crucial concern for car owners. Especially during humid seasons or in high-humidity areas, mold, unpleasant odors, and moisture damage to electronic devices can easily occur inside the car, affecting the driving experience and the vehicle's lifespan. Therefore, automotive dehumidifiers have become widely used in the market and are an important tool for managing the in-car environment.

[0003] Currently, most common car dehumidifiers on the market are traditional dehumidifier bags or boxes, which mainly rely on moisture-absorbing materials to absorb moisture inside the car. However, they lack real-time monitoring and intuitive display of humidity changes. While some products are equipped with humidity indicators, they rely on a single sensing method, which is prone to errors due to environmental interference or material aging, affecting their effectiveness. Furthermore, the installation of existing dehumidifiers is cumbersome, usually requiring fixed accessories, which is not only inconvenient to operate but may also affect the aesthetics of the vehicle interior. Therefore, there is an urgent need for a car dehumidifier that can accurately display humidity changes, has multiple verification mechanisms, is easy to install, and has a stable structure, to improve user experience and safety. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a car dehumidifier bag. Through the dual sensing of humidity expansion blocks and test strips, it accurately displays the humidity inside the car, improving dehumidification efficiency and reliability. The box and base adopt a double fixing structure of magnetic attraction and buckle, which is convenient to install, stable and durable, requires no power supply, and enhances safety during use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a car dehumidifier bag, comprising a box body, transparent windows on both the front and rear sides of the box body, a humidity scale line in the center of the transparent window, a humidity-sensing test strip inside the transparent window, a humidity expansion block placed in the bottom of the box body, a sliding groove on the inner wall of the box body, a lever slidably connected to the inner wall of the sliding groove, a first magnet fixedly connected to the center of the bottom of the box body, a second magnet magnetically connected to the lower end of the first magnet, a base fixedly connected to the lower end of the second magnet, and locking blocks connected to the left and right ends of the base via sliding components, with locking slots on both the left and right sides of the bottom of the box body.

[0006] Furthermore, the sliding assembly includes sliding blocks slidably connected to the inner walls of the left and right ends of the base. A spring is provided on one side of the sliding block, and a connecting rod is fixedly connected to the upper end of the other side of the sliding block. One side of the locking block is fixedly connected to the outer side of the upper end of the connecting rod.

[0007] Furthermore, one end of the spring is connected to the inner wall of the base, and the other end of the spring is connected to one side of the sliding block.

[0008] Furthermore, the outer wall of the card block is engaged with the inner wall of the card slot.

[0009] Furthermore, a cover plate is threadedly connected to the upper end of the inner wall of the box, and a fixing block is fixedly connected to the upper end of the cover plate.

[0010] Furthermore, ventilation holes are provided on the left and right sides of the box body, and strong adhesive is provided at the lower end of the base.

[0011] Furthermore, the lower end of the lever is placed on the upper end of the humidity expansion block.

[0012] This utility model has the following beneficial effects: In this invention, the expansion of a humidity-absorbing block moves a lever, which, in conjunction with three humidity levels on a transparent window, provides a clear display of humidity changes. Simultaneously, a built-in humidity-sensing test strip changes from blue to pink upon contact with moisture, creating a dual verification mechanism. This effectively avoids errors that may arise from a single sensing method, allowing users to more confidently monitor the humidity level inside the vehicle, thus improving dehumidification efficiency and reliability. In this invention, the box and base are secured by a combination of magnetic adsorption and snap-fit ​​structure. During installation, simple alignment is all that's needed for automatic and secure connection, requiring no additional tools or power supply. This purely mechanical design is not only simple and durable, but also significantly reduces installation difficulty, allowing users to easily secure the product and ensuring its stability and durability during use.

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Reference Figure 1 and Figure 2 An embodiment of this utility model provides a car dehumidifier bag, including a box body 1, transparent windows 2 on both the front and rear sides of the box body 1, humidity scale lines 3 in the middle of the transparent windows 2, humidity sensing test strips 4 inside the transparent windows 2, a humidity expansion block 5 placed at the bottom of the box body 1, a sliding groove 6 on the inner wall of the box body 1, a lever 7 slidably connected to the inner wall of the sliding groove 6, the lower end of the lever 7 placed on the upper end of the humidity expansion block 5, a cover plate 9 threadedly connected to the upper end of the inner wall of the box body 1, a fixing block 10 fixedly connected to the upper end of the cover plate 9, and ventilation holes 8 on the left and right sides of the box body 1.

[0017] Specifically, this dehumidifier uses a box structure 1, inside which is a humidity expansion block 5 made of highly absorbent resin. When the humidity expansion block 5 needs replacement, simply rotate the fixing block 10, causing the cover plate 9 to rotate, thus removing the cover plate 9 and replacing the humidity expansion block 5. When the humidity inside the car increases, moisture enters the box 1 through the vent 8. After absorbing moisture, the humidity expansion block 5 expands in volume by 2 to 3 times, thus pushing the central lever 7 upwards. The two ends of the lever 7 point to the humidity scale lines 3 on the transparent window 2. The scale lines are divided into three states: dry, normal, and humid. Users can clearly understand the current humidity level inside the car by directly observing the position of the lever 7. In addition, the product is equipped with humidity-sensing test strips 4. When the humidity increases, the test strips gradually change from blue to pink, serving as an auxiliary indicator and providing dual verification, effectively reducing errors that may arise from a single sensing method. This device requires no battery power and operates solely through a mechanical structure, which not only improves reliability but also reduces operating costs.

[0018] Reference Figure 1 , Figure 3 and Figure 4A first magnet 11 is fixedly connected to the middle of the bottom of the box body 1. A second magnet 12 is magnetically connected to the lower end of the first magnet 11. A base 13 is fixedly connected to the lower end of the second magnet 12. Sliding blocks 15 are slidably connected to the inner walls of the left and right ends of the base 13. A spring 16 is provided on one side of the sliding block 15. One end of the spring 16 is connected to the inner wall of the base 13, and the other end of the spring 16 is connected to one side of the sliding block 15. A connecting rod 17 is fixedly connected to the upper end of the other side of the sliding block 15. A locking block 18 is fixedly connected to the outer side of the upper end of the connecting rod 17. Slots 19 are provided on both the left and right sides of the lower end of the box body 1. The outer wall of the locking block 18 is locked into the inner wall of the slot 19. A strong adhesive backing 14 is provided at the lower end of the base 13.

[0019] Specifically, during installation, the user first fixes the base 13 to the car's center console or near the air conditioning vent using strong adhesive 14, and then aligns the lower end of the box 1 with the upper end of the base 13. At this time, the first magnet 11 at the lower end of the box 1 and the second magnet 12 on the base 13 magnetically attract each other, automatically aligning and initially fixing the box. After the locking block 18 of the box 1 contacts the edge of the slot 19, due to the arc-shaped design of the upper end of the locking block 18, it will move inward into the base 13 when squeezed, causing the connecting rod 17 and the sliding block 15 to slide in together, compressing the internal spring 16. When the locking block 18 is fully inserted into the slot 19, the rebound force of the spring 16 will push the sliding block 15 to return to its original position, so that the locking block 18 is firmly locked into the inner wall of the slot 19, achieving a stable connection. This design uses a magnet-assisted guiding function, and the double fixing structure of the locking block 18 and the slot 19, combined with the final stable connection, enhances the overall stability and durability.

[0020] Working principle: This dehumidifier bag consists of a box 1 containing a humidity expansion block 5 made of highly absorbent resin. The expansion block expands 2-3 times its original volume after absorbing water. The lever 7 is in contact with the humidity expansion block 5, with both ends pointing towards the humidity scale line 3 on the transparent window 2. The humidity scale line 3 indicates three levels: dry, normal, and humid. When the humidity inside the car increases, moisture enters the box 1 through the vent 8. The expansion block absorbs water and expands, pushing the lever 7 along the humidity scale line 3. Users can visually judge the dehumidification status by observing the position of the lever 7. Simultaneously, the humidity sensor paper 4 changes color when wet, changing from blue to pink. When installing the box 1, first attach the base 13 to the car's center console or near the air conditioning vent using strong adhesive 14, then align the lower end of the box 1 with the upper end of the base 13. At this time, the first magnet 11 and the second magnet 12 are attracted by each other and automatically align. The locking block 18 first touches the edge of the slot 19. Since the upper end of the locking block 18 is curved, the locking block 18 moves closer to the base 13 under the action of the squeezing force. The connecting rod 17 moves accordingly, driving the sliding block 15 to slide into the base 13 and compressing the spring 16. When the locking block 18 enters the slot 19, the rebound force of the spring 16 pushes the sliding block 15 to move outward. The connecting rod 17 and the locking block 18 move outward accordingly, so that the locking block 18 is locked in the inner wall of the slot 19, thus fixing the box 1 to the base 13.

[0021] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
