[0001] The utility model relates to the technical field of earphones, and specifically discloses a plug-in and disassembly structure for earplugs. Background Art

[0002] The structure of a wireless earphone includes a ear shell assembly and a sound outlet nozzle. In the past, after the ear shell assembly and the sound outlet nozzle were assembled and fixed, they were not detachable. With the development of wireless earphones, the connection between the ear shell assembly and the sound outlet nozzle has been improved to be detachable, so as to replace different ear shell assemblies according to the needs and scenarios of users. For example, in a sports scenario, the earphone needs to have good wearing stability, and the ear shell assembly may be replaced with one with an ear hook or bone conduction technology. For those who pursue sound quality performance, comfort and sound effect become particularly important, and the ear shell assembly may be replaced with a design that fits the contour of the ear to provide a better music experience.

[0003] For the existing earphones with replaceable ear shell assemblies, generally, the ear shell assembly and the sound outlet nozzle are connected by a buckle structure. During the disassembly and assembly process of such a buckle structure, force needs to be applied to deform the material at the buckle connection position. In this way, multiple disassembly and assembly operations will cause wear to the material of the ear shell assembly, which will not only reduce the connection reliability and stability at the buckle, but also be unfavorable to the service life of the earphone. Therefore, a plug-in and disassembly structure for earplugs that is convenient for disassembly and assembly and has reliable connection is needed. Summary of the Utility Model

[0026] To make the above objects, features, and advantages of the present utility model more obvious and understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] This embodiment discloses a disassembly and assembly structure of earplugs. Referring to Figures 1-6 , it includes an ear shell assembly 2 and a sound outlet nozzle assembly. The ear shell assembly 2 includes an ear shell body, a sound-absorbing cotton 24 disposed inside the ear shell body, and a protective sleeve 23 that at least covers a part of the outer surface of the ear shell body. The protective sleeve 23 can specifically be a silica gel sleeve. The ear shell body includes an ear shell 21 and an ear shell cover 22 that are snap-fitted to each other. The sound outlet nozzle assembly includes a sound outlet nozzle 1. Among them, an installation groove 221 is provided at the end of the ear shell cover 22, and an installation block 222 is provided on the inner wall of the installation groove 221. The sound outlet nozzle 1 is provided with a mounting post 11 that is inserted into cooperation with the installation groove 221. A circumferentially extending clamping groove 111 is provided on the surface of the mounting post 11, and a notch 112 communicating with the end of the mounting post 11 is provided in the clamping groove 111. The mounting block 222 enters the clamping groove 111 through the notch 112 and is fixed after rotation. By adopting the above design, the sound outlet nozzle 1 can be inserted and then rotated to be clamped and fixed with the ear shell assembly 2. Different from the existing method of fixing by deforming the buckle, the rotation clamping method of this embodiment is more convenient for disassembly and assembly. It is not only easy to disassemble and assemble, has a reliable connection, but also is not easy to cause wear to the sound outlet nozzle 1 or the ear shell assembly 2 after multiple disassembly and assembly. The connection stability is good and the service life is more guaranteed.

[0028] In this embodiment, the sound outlet nozzle 1 is provided with an abutting platform 12, and the protective cover 23 is provided with a sealing end 231 that extends and wraps around the end edge of the ear shell cover 22. The sealing end 231 of the protective cover 23 is clamped between the end of the ear shell cover 22 and the abutting platform 12, which not only makes the sealing between the sound outlet nozzle 1 and the ear shell assembly 2 better, but also increases the friction between the protective cover 23 and the sound outlet nozzle 1, thereby helping to further improve the connection stability between the sound outlet nozzle 1 and the ear shell assembly 2. As a preferred solution, the clamping groove 111 is inclined. In this way, the mounting post 11 of the sound outlet nozzle 1 is assembled into the mounting groove 221 of the ear shell assembly 2 in a spiral manner. The spiral assembly method not only has higher connection reliability, but also helps the abutting platform 12 of the sound outlet nozzle 1 to better clamp and hold the sealing end 231 of the protective cover 23 during the spiral assembly process, reducing the dragging and wear of the sealing end 231 of the protective cover 23.

[0029] In this embodiment, see Figures 4-6 , a locking protrusion 113 is provided in the clamping groove 111, and a locking groove 223 is provided on the side wall of the mounting block 222. After the mounting block 222 enters the end of the clamping groove 111, the locking protrusion 113 is clamped into the locking groove 223. As a preferred solution, a guiding inclined surface 224 is further provided on the side wall of the mounting block 222, and the locking protrusion 113 slides into the locking groove 223 along the guiding inclined surface 224. By adopting the above design, the locking protrusion 113 has a certain locking effect on the mounting block 222, which is beneficial to improving the connection stability between the sound outlet nozzle 1 and the ear shell assembly 2 and is not prone to loosening. The guiding inclined surface 224 helps the smoothness of the locking process. In addition, a chamfer 225 is provided at one end of the mounting block 222 facing the inner wall of the clamping groove 111. In this way, there is a gap between the end of the mounting block 222 with the chamfer 225 and the clamping groove 111, which helps to improve the smoothness of the rotation process and makes it easier for the user to disassemble and assemble.

[0030] In this embodiment, the ear shell assembly 2 is provided with two pressure relief holes 201 that are symmetrically arranged left and right, so that the user does not need to distinguish between left and right when wearing, improving the flexibility of disassembly, installation and replacement of the ear shell assembly.

[0031] In this embodiment, two mounting blocks 222 are symmetrically arranged at intervals on the inner wall of the mounting groove 221, and two groups of clamping grooves 111 corresponding to and mating with the two mounting blocks 222 are provided on the surface of the mounting post 11. By adopting the above design, the connection stability and reliability between the sound outlet nozzle 1 and the ear shell assembly 2 are better.

[0032] In this embodiment, the sound outlet nozzle assembly further includes a mesh cloth 13, and the mesh cloth 13 is arranged between the bottom wall of the mounting groove 221 and the end of the mounting post 11, playing a certain role in dust and dirt prevention.

[0033] In this embodiment, a connecting groove 226 is provided on the outer periphery of the end portion of the ear shell cover 22, and a connecting ring 232 is provided on the inner periphery of the protective sleeve 23. By fitting the connecting ring 232 with the connecting groove 226 in a matching manner, the protective sleeve 23 is covered and fixed outside the ear shell body. Of course, in other embodiments, it can also be connected and fixed by other means.
