Description

Technical Field

[0001] This utility model relates to the field of Bluetooth speaker technology, specifically a waterproof and sealed structure for Bluetooth speaker packaging boxes. Background Technology

[0002] With the continuous innovation of Bluetooth technology and the growing demand for outdoor entertainment, Bluetooth speakers have become popular products in the audio market due to their portability and multifunctionality. During product transportation, warehousing, and sales, the packaging box not only plays a basic role in protecting the speaker from physical damage, but also needs to cope with the threats of humidity and water stains in complex environments. Especially in outdoor use scenarios, maritime logistics, or high-humidity warehousing environments, moisture intrusion may cause short circuits and component corrosion inside the speaker, thereby affecting product performance and lifespan. Therefore, packaging boxes with efficient waterproof and sealing performance have become a key link in ensuring the quality and reliability of Bluetooth speakers.

[0003] Currently, most traditional Bluetooth speaker packaging boxes on the market use a single sealing material or a simple snap-fit ​​structure. For example, some packaging boxes rely solely on a rigid outer shell with ordinary sealing strips. Under long-term transportation vibrations or extreme temperature and humidity changes, the sealing strips are prone to aging and cracking, leading to sealing failure. Other products, although using snap-fit ​​designs, are prone to loosening after frequent opening and closing, failing to provide a stable sealing pressure. In addition, traditional packaging lacks targeted design for internal moisture protection, making it difficult to resist moisture penetration. These technical defects not only increase the product's loss rate during distribution but may also lead to user doubts about product quality, thereby affecting brand reputation and market competitiveness. To address this, we propose a waterproof sealing structure for Bluetooth speaker packaging boxes. Utility Model Content

[0052] Working Principle: In terms of structural composition, the moisture-proof liner 2, silicone sealing ring 3, and waterproof packaging shell 4 constitute the core waterproof system. The moisture-proof liner 2 is placed inside the waterproof packaging shell 4, and the gap between the two is filled by the silicone sealing ring 3. A rubber pad 1 is provided on the top of the moisture-proof liner 2, and the top of the waterproof packaging shell 4 is equipped with a symmetrically distributed first cover plate 5 and second cover plate 6. The two are connected by a connecting component to achieve opening, closing, and fixation. During packaging, the Bluetooth speaker is first placed in the Bluetooth speaker placement slot 9 on the top of the moisture-proof liner 2. The bottom of the moisture-proof liner 2 and the inside of the waterproof packaging shell 4 are precisely installed and positioned through the sliding cooperation of the connecting groove 10 and the connecting block 15, ensuring that the moisture-proof liner 2 is firmly placed in the waterproof packaging shell 4. At this time, the vacuum cavity 11 inside the bottom of the moisture-proof liner 2 forms a low-pressure environment, which can effectively block moisture intrusion and provide initial moisture protection for the speaker. Then, the first cover plate 5 and the second cover plate 6 are closed. The bottom of the two are tightly attached to the rubber pad 1, forming a physical barrier to prevent external moisture from entering from the top. The connecting component plays a key role in this process. Rotating the rotating handle ring 7 causes the rotating handle sleeve 14 at its bottom end to rotate within the connecting hole of the second cover plate 6, driving the hook 8 to make a circular motion within the hook movable cavity 13. When the end of the hook 8 rotates to the fixing hole on the left end face of the first cover plate 5 and engages with the positioning blocks on both sides of the fixing hole, the first cover plate 5 and the second cover plate 6 are firmly fixed, achieving the closure of the packaging box. During the sealing and protection process, the silicone sealing ring 3 plays a crucial role. After the first cover plate 5 and the second cover plate 6 are closed and fixed, the silicone sealing ring 3 is squeezed by the moisture-proof liner 2 and the waterproof packaging shell 4, undergoing elastic deformation, filling the tiny gaps between them, forming a tight sealing layer, effectively preventing external water, moisture, dust, etc. from entering the packaging box. Through the initial moisture-proofing of the vacuum cavity 11 of the moisture-proof liner 2, the physical blocking of the rubber pad 1, the first cover plate 5 and the second cover plate 6, the stable fixing of the connecting components, and the sealing effect of the silicone sealing ring 3, multiple layers of protection work together to comprehensively protect the Bluetooth speaker from water, moisture, and other factors during transportation and storage, ensuring its stable performance.

[0053] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
