[0029] In the description of the present utility model, unless otherwise specified, "a plurality of" means two or more. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0030] In an embodiment of the present utility model, as Figures 1-4 shown, a waterproof structure of a Bluetooth headset case is provided, which includes a charging case 10, a case cover 20, and a power supply module 30. A first gasket 11 is provided inside the charging case 10. A sealing layer 12 is provided on the first gasket 11. A downwardly concave first fixing groove 13 is provided on the top surface of the sealing layer 12, and an upwardly protruding sealing strip 14 is provided inside the first fixing groove 13. A second gasket 21 is provided inside the case cover 20. A first sealing ring 22 corresponding to the fixing groove is provided on the bottom surface of the second gasket 21. The sealing strip 14 passes through the center of the first sealing ring 22 and extends into the second gasket 21. The power supply module 30 is provided inside the first gasket 11. A charging head 31 is provided between the power supply module 30 and the charging case 10. A sealing sleeve 15 is provided between the charging head 31 and the charging case 10.

[0031] By providing the first fixed groove 13, the first sealing ring 22 and the sealing strip 14, the gap at the connection between the charging bin 10 and the bin cover 20 is formed into a maze structure, so that the water is blocked in the first fixed groove 13, and the water is separated from the first liner 11 by the sealing layer 12, so as to avoid the water contacting the power supply module 30 and causing a short circuit, thereby improving the service life of the Bluetooth charging bin 10. At the same time, by providing a sealing sleeve 15 on the charging head 31, when not charging, by sleeve-connecting the sealing sleeve 15 on the charging bin 10, the water is further prevented from entering the power supply module 30, thereby improving the service life of the Bluetooth charging bin 10.

[0032] Preferably, a first connection portion corresponding to the sealing strip 14 is provided in the first sealing ring 22. A second connection portion is provided between the second lining layer and the sealing strip 14. The first connection portion and the second connection portion form a second fixed groove 23. The sealing strip 14 can enter or disengage from the second fixed groove 23. Through the first fixed groove 13, the first sealing ring 22, the sealing strip 14 and the second fixed groove 23, the gap at the connection between the charging bin 10 and the bin cover 20 is a maze structure, which blocks the water in the first fixed groove 13 and cannot easily enter the power supply module 30, thereby improving the service life of the Bluetooth charging bin 10.

[0033] Furthermore, a circular arc portion protruding outward is provided on the inner side of the top of the sealing strip 14. The second fixing groove 23 is provided with a circular arc groove corresponding to the circular arc portion. The circular arc portion can enter or leave the circular arc groove. By providing the circular arc portion and the circular arc groove, the connection between the charging compartment 10 and the compartment cover 20 is made more secure, and the connection stability between the charging compartment 10 and the compartment cover 20 is improved.

[0034] Preferably, the sealing sleeve 15 includes a rotating portion 151 and a blocking portion 152. The rotating portion 151 is rotatably arranged on one side of the charging compartment 10. The blocking portion 152 is located outside the charging head 31 and is connected to the rotating portion 151. The charging compartment 10 and the blocking portion 152 are provided with a charging slot. The charging slot is sealed and connected to the blocking portion 152. When the charging compartment 10 is taken out, the charging slot is blocked by inserting the blocking portion 152 into the charging slot to prevent water from entering the power supply module 30 from the charging slot, thereby improving the service life of the Bluetooth charging compartment 10.

[0035] Furthermore, a second sealing ring 153 is provided inside the blocking portion 152. A third fixing groove corresponding to the charging head 31 is provided inside the second sealing ring 153, and the charging head 31 can enter or leave the third fixing groove. By providing the second sealing ring 153, water is further prevented from entering the charging groove. At the same time, the second sealing ring 153 can be mutually connected with the charging head 31 to prevent dust from entering the charging head 31 and reduce dust accumulation.

[0036] Furthermore, the outer diameter of the second sealing ring 153 is equal to the inner diameter of the charging slot. By setting the outer diameter of the second sealing ring 153 to be equal to the inner diameter of the charging slot, the second sealing ring 153 can be hermetically connected to the charging slot, preventing water and liquid from entering the power supply module 30 from the charging slot and increasing the service life of the Bluetooth charging case 10.

[0037] Preferably, a first placement slot 16 for positioning the earphone is provided between the first gasket 11 and the sealing layer 12. The bottom surface of the second gasket 21 is provided with a second placement slot 24 for positioning the earphone. A placement cavity is formed between the first placement slot 16 and the second placement slot 24. The Bluetooth earphone is fixed through the placement cavity, preventing the Bluetooth earphone from easily shaking inside the Bluetooth earphone case.

[0038] Further, a fixing sleeve is provided in the second placement slot 24. The fixing sleeve includes a first fixing ring 241 and a second fixing ring 242. The first fixing ring 241 and the second fixing ring 242 are distributed left and right in the second placement slot 24, and a first fixing bar 243 is provided between the first fixing ring 241 and the second fixing ring 242. Second fixing bars 244 are provided between the first fixing ring 241, the second fixing ring 242 and the second placement slot 24 respectively. The first fixing ring 241, the second fixing ring 242, the first fixing bar 243 and the second fixing bar 244 are made of elastic materials. The outer diameter of the first fixing ring 241 is equal to the outer diameter of the second fixing ring 242. By providing the first fixing ring 241, the second fixing ring 242, the first fixing bar 243 and the second fixing bar 244 to further fix both ends of the Bluetooth earphone, the fixing effect of the Bluetooth earphone case on the Bluetooth earphone is improved, and since the first fixing ring 241, the second fixing ring 242, the first fixing bar 243 and the second fixing bar 244 are made of elastic materials, the pressing force on the Bluetooth earphone is softer, protecting the Bluetooth earphone.

[0039] Preferably, a first magnet 17 is provided on the top surface of the charging case 10. A second magnet 25 corresponding to the first magnet 17 is provided on the bottom surface of the lid 20. By providing the first magnet 17 and the second magnet 25, the charging case 10 and the lid 20 are fixed by magnetic attraction, simplifying the opening or closing of the charging case 10 and the lid 20 and facilitating the use of the user.

[0040] The above are only preferred embodiments of the present invention, and do not impose any form of limitation on the present invention. Although the present invention is disclosed above in preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art, without departing from the scope of the technical solution of the present invention, when making some changes or modifications using the above-disclosed technical content into equivalent embodiments of equivalent changes, but as long as it does not depart from the content of the technical solution of the present invention, any simple modification, equivalent change and modification made to the above embodiments according to the technical meaning of the present invention shall fall within the scope of the technical solution of the present invention.
