[0023] 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.

[0024] Please see Figure 1-6 This utility model provides a technical solution: a waterproof and sweatproof Bluetooth headset breathable cavity, comprising:

[0025] The earphone cavity 1 has a waterproof base 3 embedded in the ear-in end of the earphone cavity 1, which waterproofs the ear-in end of the earphone cavity 1.

[0026] The tail end of the earphone cavity 1 is snapped with a bottom cover 5, and a charging unit 6 is provided between the bottom cover 5 and the earphone cavity 1. The charging unit 6 enables the two ends of the earphone cavity 1 to be connected to the air inside the ear canal and the outside air respectively to balance the air pressure.

[0027] The sound unit 2 includes components such as a speaker, battery, and circuit board (existing technology, which will not be described in detail here). By placing the entire earphone cavity 1 inside the earphone case, the sound unit 2 is charged using the charging copper plate 61, thereby improving the convenience of using Bluetooth earphones.

[0028] In this embodiment, the charging unit 6 includes two sets of charging copper sheets 61, one set of charging copper sheets 61 is provided with a vent hole 62, an anti-overflow beam 63 is fixedly connected in the vent hole 62, and a second waterproof and breathable membrane 64 is bonded to one side of the anti-overflow beam 63.

[0029] Specifically, the charging copper sheet 61 achieves both breathability and waterproofing while ensuring conductivity. The anti-overflow beam 63 (a rectangular frame beam) can prevent liquid from directly impacting the breathable membrane and facilitates the installation of the second waterproof and breathable membrane 64. The second waterproof and breathable membrane 64 only allows gas to pass through, effectively preventing moisture from seeping into the earphone through the charging unit 6, thus improving the reliability of the seal at the tail end of the earphone cavity 1.

[0030] Furthermore, the earphone cavity 1 includes an earphone stem 11 and a cover 13. A connecting plate 12 is fixedly connected to the upper end of the earphone stem 11, and multiple sets of first locking blocks 16 are fixedly connected to the open end of the cover 13. The cover 13 is locked onto the connecting plate 12 by multiple sets of first locking blocks 16, and a second sealing ring 17 adapted to the opening of the cover 13 is adhered to the connecting plate 12.

[0031] Specifically, the second sealing ring 17 enhances the sealing performance of the connection, preventing liquid from seeping in from the gap between the cover 13 and the earphone stem 11, thus avoiding damage to the sound unit 2.

[0032] Secondly, the inner cavity of the earphone cavity 1 is equipped with a sound-generating unit 2, and the outer side of the cover 13 is provided with a mounting groove 14 for mounting the speaker end of the sound-generating unit 2, and the inner wall of the mounting groove 14 is embedded with a first sealing ring 15, and the waterproof base 3 is bonded to the mounting groove 14.

[0033] It is worth noting that the mounting groove 14 provides installation space for the waterproof base 3. The first sealing ring 15 fits tightly with the waterproof base 3, which improves the installation stability of the waterproof base 3 and seals the installation gaps, further improving the sealing effect at the earpiece end and preventing moisture from entering the sound unit 2 and affecting the sound quality or causing damage.

[0034] The insert 31 is used for a tight seal with the mounting slot 14. The first waterproof and breathable membrane 33 enables local ventilation at the ear canal end, which can balance the micro-air pressure between the ear canal and the inner cavity of the earphone, relieve the stuffiness during wearing, and at the same time prevent moisture from entering, improving the comfort of wearing the earphone cavity 1. The rubber earplug 4 is inserted into the rubber sleeve 32, and the friction is increased through the rubber insertion, thereby improving the installation stability of the rubber sleeve 32. Both the first waterproof and breathable membrane 33 and the second waterproof and breathable membrane 64 are ePTFE membranes (expanded polytetrafluoroethylene, existing technology, which will not be described in detail).

[0035] Meanwhile, the waterproof base 3 includes a sleeve 31 that is bonded to the bottom of the mounting groove 14 and fits against the first sealing ring 15. One end of the sleeve 31 is fixedly connected to a rubber sleeve 32. A first waterproof and breathable membrane 33 is bonded to the side of the rubber sleeve 32 near the sleeve 31. The inner diameter of the rubber sleeve 32 is smaller than the inner diameter of the sleeve 31.

[0036] The contact and cooperation between the first irregular sealing ring 111 and the second irregular sealing ring 52 can effectively prevent liquid from seeping in from the tail end gap, providing reliable protection for the charging unit 6, while not affecting the air circulation of the ventilation channel. In addition, the first irregular sealing ring 111 is in contact with the outer side of the charging copper sheet 61, thereby preventing liquid from seeping into the earphone cavity 1 from the installation gap of the charging unit 6.

[0037] Two sets of second locking blocks 51 are fixedly connected to the upper surface of the bottom cover 5. Two sets of slots 110 for the second locking blocks 51 to be inserted are opened at the lower end of the earphone stem 11. A second irregular sealing ring 52 is embedded on the upper surface of the bottom cover 5. A first irregular sealing ring 111 that abuts against the second irregular sealing ring 52 is embedded at the lower end of the earphone stem 11.

[0038] A rubber earplug 4 is inserted into the waterproof base 3. An adjustment part 18 and an anti-slip part 19 are provided on the outside of the earphone stem 11. The adjustment part 18 and the anti-slip part 19 are arranged vertically in a staggered manner. The adjustment part 18 makes it convenient for users to operate quickly when wearing the earphone (such as touch control to switch songs or adjust the volume), while the anti-slip part 19 enhances the grip friction and prevents the earphone from slipping off when wearing or operating, thus improving the ease of operation.

[0039] When using the earphone cavity 1, air from inside the ear canal can enter the inner cavity of the earphone cavity 1 through the first waterproof and breathable membrane 33 of the waterproof base 3, and then pass through the second waterproof and breathable membrane 64 through the vent 62 on the charging copper plate 61 of the charging unit 6, connecting with the external ambient air to form a complete breathable channel. When the user moves, the altitude changes, or the ambient temperature fluctuates, causing changes in the air pressure inside the ear canal or the inner cavity of the earphone, air can flow bidirectionally through this channel. That is, when the air pressure increases, the internal air is discharged to the outside, and when the air pressure decreases, the external air is replenished to the inside, thereby balancing the air pressure difference between the ear canal, the inner cavity of the earphone, and the external environment in real time. This avoids stuffiness, deformation of the sealing structure, or impact on sound quality caused by air pressure imbalance, thereby improving wearing comfort.

[0040] 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.
