Description

Technical Field

[0001] This utility model relates to the field of wireless earphone technology, specifically to an easy-to-clean wireless earphone and charging case. Background Technology

[0002] In the existing market of wireless earphone and charging case combinations, traditional charging cases have significant shortcomings in terms of cleanliness and protection. Most charging cases have simple internal structures, and after frequent use, ear hair, earwax, and other dirt accumulate on the charging area of ​​the earphones. During charging, this dirt easily enters the charging case, and long-term accumulation not only affects the aesthetics of the case but also obstructs the normal contact of the charging contacts, leading to unstable charging or even failure to charge, thus reducing the user experience and lifespan of the earphones. Furthermore, traditional charging cases lack a buffer structure between the top and bottom covers. When closing the case, the hinge causes the top cover to contact the bottom half of the case quickly, resulting in a loud closing sound. In addition, cleaning the inside of traditional charging cases is very difficult; ordinary wiping is insufficient to completely remove stubborn dirt, causing inconvenience to users. Therefore, this paper proposes a solution for easily cleanable wireless earphones and charging cases to address the above problems. Utility Model Content

When you need to clean the charging case, hold the thin metal rod 12 and pull it outwards to move the foam ring 10 and remove the dirt from the earphone placement hole.

[0028] Example 3: This example features an easy-to-clean charging case and wireless earphone assembly. The lower charging case cover 1 and the upper charging case cover 2 are connected by a hinge 7, which is made of plastic with a smooth surface for easy rotation. Inside the lower charging case cover 1, the charging case PCBA board 3 is fixed to the left side of the inner cavity via a slot, the battery 6 is fixed to the side wall of the inner cavity with double-sided adhesive, and the lower charging case liner 4 is fixed to the inner cavity with hot melt adhesive.

The foam ring 10 inside the earphone placement hole is made of high-density foam, and the conductive gel pad 11 is made of flexible conductive gel material, molded and fixed inside the foam ring 10. The thin metal rod 12 is made of stainless steel, with one end fixed to the side wall of the foam ring 10 by riveting, and the other end extending to the outside of the earphone placement hole and embedded in the groove. The power supply contact of the charging case PCBA board 3 is a spring contact, which makes elastic contact with the surface of the conductive gel pad 11 to ensure good contact. In the Bluetooth earphone component 5 of the wireless earphone, the earphone back shell 5-1 and the earphone front cover 5-5 are fixed together by threads, and the speaker 5-4 is fixed to the inner cavity of the earphone front cover 5-5 by glue. The earphone battery 5-6 is fixed to the head section of the inner cavity of the earphone back shell 5-1 by dispensing glue, the earphone PCBA board 5-2 is fixed to the tail section by clips, and the charging plug 5-3 is made of elastic metal and is fixed to the tail end of the earphone back shell 5-1 by interference fit. When the Bluetooth earphone component 5 is placed in the charging case, the charging plug 5-3 contacts the conductive gel pad 11 for charging, and the conductive gel pad 11 isolates dirt. During cleaning, pull the thin metal rod 12 to move the sponge ring 10 in the earphone placement hole to remove dirt.

[0029] Based on the above-described preferred technical solution, the workflow of this technical solution is explained as follows:

[0030] Place the charging case bottom cover 1 horizontally, install the charging case PCBA board 3 into the designated position on the left side of the inner cavity of the charging case bottom cover 1 and fix it, so that the USB port on the right side of the charging case PCBA board 3 is exposed from the opening on the left end face of the charging case bottom cover 1, so as to connect to an external power source for charging or data transmission later; then fix the battery 6 in the preset position on the side wall of the inner cavity of the charging case bottom cover 1 to power the entire charging case and wireless earphones; then install the charging case lower liner 4 into the inner cavity of the charging case bottom cover 1, and the two earphone placement holes inside are used to place the Bluetooth earphone components 5 of the wireless earphones. Then, snap the foam ring 10 into the inner cavity of each earphone placement hole, with the outer surface of the foam ring 10 in contact with the inner wall of the earphone placement hole, and fix the conductive gel pad 11 in the inner cavity of the foam ring 10. The two thin metal rods 12 on the side wall extend to the outside of the earphone placement hole and are embedded in the grooves opened on the inner side wall of the earphone placement hole. Then, the two power supply contacts on the right side of the charging case PCBA board 3 are inserted into the inner cavity of the lower liner 4 of the charging case, so that the power supply contacts contact the surface of the conductive gel pad 11 for subsequent charging of the Bluetooth earphone 5 placed in the charging case. At this time, the silicone ring 9 is evenly adhered to the end face of the lower cover 1 of the charging case near the upper cover 2 of the charging case using adhesive. A gap is left between the lower cover 1 and the upper cover 2 of the charging case to accommodate the silicone ring 9. The left and right ends of the silicone ring 9 can seal the gap between the two, while preventing the upper cover 2 of the charging case from colliding with the lower cover 1 of the charging case after it is closed.

[0031] When the charging case is needed, open the top cover 2 of the charging case and place the two Bluetooth earphones 5 into the two earphone placement holes in the lower liner 4 of the charging case. The charging end of the charging plug 5-3 of the Bluetooth earphone 5 contacts the side of the conductive gel pad 11 away from the power supply contact. At this time, the charging case PCBA board 3, conductive gel pad 11, charging plug 5-3, earphone PCBA board 5-2, and earphone battery 5-6 form a charging circuit to start charging the Bluetooth earphones 5. At the same time, the conductive gel pad 11 acts as an insulator to prevent ear hair and earwax carried by the Bluetooth earphones 5 from entering the inner cavity of the lower liner 4 of the charging case. When the Bluetooth earphones 5 are fully charged and need to be removed for use, open the top cover 2 of the charging case and take out the Bluetooth earphones 5. At this time, the charging case can be cleaned. Pull the thin metal rod 12. The metal rod 12 pulls the foam ring 10 to move inside the earphone placement hole. During the movement, the foam ring 10 carries out the dirt inside the earphone placement hole, thus cleaning the charging case. For the Bluetooth earphone component 5 of the wireless earphone, when needed, it is taken out of the charging case. The earphone battery 5-6 in the head section of the earphone back shell 5-1 powers the earphone PCBA board 5-2. The earphone PCBA board 5-2 controls the speaker 5-4 to emit sound, realizing the normal use function of the earphone. After use, the charging tail plug 5-3 of the Bluetooth earphone component 5 is aligned with the conductive gel pad 11 in the earphone placement hole of the lower liner 4 of the charging case. With the magnet in the charging case attracting the earphone, the charging tail plug 5-3 of the attracted earphone will contact the conductive gel pad 11, and force the conductive gel pad 11 to contact the power supply contact piece, thereby realizing charging for the next use.
