The following examples are used to illustrate the technical solution of this utility model, but should not be used to limit the scope of protection of this utility model.

[0025] Example:

[0026] like Figures 1 to 4 As shown, this utility model provides a dustproof Bluetooth headset, including a mounting frame 11 and a display module 18. The mounting frame 11 contains a mounting base 12, and one side of the mounting base 12 has two sets of earphone slots, each containing an earphone 13. The mounting frame 11 has a protective cover 14 corresponding to the top of the earphone 13, and the protective cover 14 contains a mounting plate 16. One side of the mounting plate 16 has two sets of miniature vacuum cleaner motors 15 and two sets of detachable ear hooks 17. The top of the mounting base 12 also has a mounting slot, within which the display module 18 is located. The mounting frame 11 and mounting base 12 have charging holes corresponding to the display module 18. A snap-fit ​​assembly is provided on one side of the mounting base 12 and mounting frame 11. With this structural setup, the mounting frame 11 provides support for the whole, the mounting base 12 is used to support components such as the earphone 13, the protective cover 14 can cover the earphone 13 when stored to reduce dust entry, the miniature vacuum motor 15 can clean dust, the detachable ear hook 17 allows users to wear it according to their needs, the display module 18 can be an SSD-1306 model to display the device status, the charging port is used for power supply, and the buckle assembly realizes the opening and closing of the protective cover 14.

[0027] like Figure 3 and Figure 4 As shown, the snap-fit ​​assembly includes a button 19. A mounting hole is provided on one side of the button 19, and a push rod 21 is installed inside the mounting hole. A limiting plate 22 is provided at one end of the push rod 21, and a limiting protrusion is provided on one side of the limiting plate 22. A return spring 23 is fitted onto the limiting protrusion. When it is necessary to open the protective cover 14, pressing the button 19 causes the button 19 to push the limiting plate 22 to move via the push rod 21, compressing the return spring 23 and releasing the lock on the protective cover 14. After releasing the button 19, the return spring 23 rebounds, causing the limiting plate 22 and the push rod 21 to return to their original positions, ensuring that the snap-fit ​​assembly can be reused and enhancing the ease of opening and closing the protective cover 14.

[0028] A mounting groove is provided on one side of the mounting base 12. A limiting plate 22, which is Z-shaped, slides within the mounting groove. Both ends of the limiting plate 22 have guide chamfers and protrusions, respectively. A limiting groove is provided in the mounting groove corresponding to the protrusions, with one end of the protrusion located within the limiting groove. A spring limiting groove is provided on one side of the mounting groove corresponding to the return spring 23, with one end of the return spring 23 located within the spring limiting groove. When the Z-shaped limiting plate 22 slides within the mounting groove, the guide chamfers easily engage with the limiting chamfers. The cooperation between the protrusions and the limiting groove restricts the sliding range of the limiting plate 22, preventing it from dislodging from the mounting groove. The spring limiting groove also fixes the return spring 23, ensuring that the return spring 23 can stably exert its elastic force and guaranteeing the normal operation of the snap-fit ​​assembly.

[0029] A limiting clip 24 is provided on one side of the protective cover 14 corresponding to the button 19. One end of the limiting clip 24 has an L-shaped protrusion corresponding to the limiting plate 22, and the end of the L-shaped protrusion corresponding to the guide chamfer has a limiting chamfer. When the protective cover 14 is closed, the L-shaped protrusion of the limiting clip 24 contacts the limiting plate 22. The limiting chamfer and the guide chamfer cooperate with each other to allow the limiting plate 22 to move smoothly and finally lock the L-shaped protrusion, thereby locking the protective cover 14 and preventing it from accidentally opening during impacts, thus protecting the earphone 13 from being thrown out.

[0030] like Figures 1 to 2 As shown, two sets of mounting holes are provided on one side of the mounting plate 16. Two sets of miniature vacuum cleaner motors 15 are respectively installed in the two sets of mounting holes. Each of the two sets of mounting holes and the protective cover 14 has an exhaust port corresponding to the two sets of miniature vacuum cleaner motors 15. The exhaust ends of the two sets of miniature vacuum cleaner motors 15 are respectively installed in the two sets of exhaust ports. The mounting holes provide mounting positions for the miniature vacuum cleaner motors 15, allowing them to be stably fixed on the mounting plate 16. The exhaust ports provide channels for the air discharged by the miniature vacuum cleaner motors 15, allowing the motors to smoothly expel the dust-laden air during operation. This, combined with the subsequent dust collection components, enables dust collection and improves the dustproof effect of the equipment.

[0031] The mounting plate 16 has a mounting groove on one side, and multiple sets of locking protrusions on the other side. Two sets of ear hooks 17 are detachably secured within the mounting groove. Each ear hook 17 has a corresponding loop at one end, allowing both earphones 13 to connect to the ear hooks 17 via these loops. The locking protrusions securely hold the ear hooks 17 within the mounting groove, preventing them from falling off during storage. The detachable design allows users to remove the ear hooks 17 when not in use. The connection between the loops and the earphones 13 enhances stability during wear, reducing the likelihood of the earphones 13 falling off during exercise.

[0032] The protective cover 14 is hinged to one side of the mounting frame 11. Each of the two sets of exhaust vents on the protective cover 14 has a triangular dust collection box 25. Each of the two sets of triangular dust collection boxes 25 has a ventilation hole on one side, and each ventilation hole contains a filter screen 26. The hinged connection allows the protective cover 14 to rotate freely, facilitating the user's placement and removal of the earphones 13. The triangular dust collection boxes 25 collect dust discharged from the miniature vacuum motor 15, the ventilation holes ensure airflow, and the filter screen 26 filters dust from the air, preventing dust from escaping through the ventilation holes, further enhancing the device's dustproof capability and keeping the earphones 13 clean when stored.

[0033] The specific usage and function of this embodiment are as follows:

[0034] When the user needs to use the dustproof Bluetooth headset, first press button 19. Button 19 pushes the limiting plate 22 to move via the top rod 21, compressing the return spring 23. At this time, the locking state between the protective cover 14 and the mounting frame 11 is released, and the protective cover 14 is opened by rotating around the hinge. If the detachable ear hook 17 is needed, remove the ear hook 17 from the mounting groove of the mounting plate 16 and connect its loop to the earphone 13 to enhance the stability when wearing it, which is suitable for sports and other scenarios. If it is not needed, the ear hook 17 can be snapped back into the mounting groove and fixed by the slot protrusion.

[0035] During use, the display module 18 will show information such as the battery level and connection status of the earphone 13, allowing users to easily monitor the device's status. When the earphone 13's battery is low, it can be placed into the earphone slot of the mounting base 12 and charged by connecting it to a power source through the charging port. After use, the earphone 13 can be returned to the earphone slot, and the protective cover 14 can be closed. At this time, the L-shaped protrusion of the limiting clip 24 contacts the limiting plate 22. With the cooperation of the guide chamfer and the limiting chamfer, the limiting plate 22 moves and then resets, achieving a lock through the cooperation of the protrusion and the limiting groove, preventing the protective cover 14 from accidentally opening during impacts.

[0036] After the protective cover 14 is closed and the power is turned on, the miniature vacuum motor 15 starts, sucking in the dust on and around the earphone 13 and discharging it into the triangular dust collection box 25 through the exhaust port. The dust in the air is intercepted in the dust collection box by the filter screen 26, and clean air is discharged from the ventilation port, reducing the impact of dust on the earphone 13, keeping the earphone 13 clean, extending its service life, and improving the user experience.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments.
