[0024] The lifting cylinder 9 is connected to the upper half of the storage cylinder 19 through the air pipe, the buffer cavity 4 is connected to the lower half of the storage cylinder 19 through the air pipe, the protective cylinder 11 is connected to the positive pressure outlet of the piezoelectric pump 18 through the air pipe, the lower half of the storage cylinder 19 is connected to the positive pressure output end of the piezoelectric pump 18 through the air pipe, and the positive pressure output end of the piezoelectric pump 18 is connected to the air duct 27 through the air pipe.

[0025] The storage cylinder 19 is fixedly connected to the top of the bottom plate 15 to store compressed gas, provide power for the system, improve the system response speed, and enhance the overall performance. The driving piston 20 is slidably connected to the inner wall of the storage cylinder 19 to control the gas flow and drive the rack 21 to move, thereby achieving precise air pressure control and improving the stability of the system.

The transmission shaft 24 is fixedly connected to the inner end of the gear 22, and both ends are rotatably connected to the outer shell 16 to transmit the power. The rotational movement of the gear 22 is transmitted to realize multi-point synchronous transmission and improve the coordination of the system.

[0026] The third implementation method: Figure 1-10 The working principle of this scheme is shown as follows: S1, automatic pop-up; When the Bluetooth headset 6 is in use, when the headset cover 26 is opened and flipped upward, the headset cover 26 rotates to drive the tooth piece 25 to rotate upward, and the rotation of the tooth piece 25 drives the gear 22 in the middle position to rotate, and the middle gear 22 drives the gears 22 at both ends to rotate through the transmission shaft 24, and the rotation of the gears 22 at both ends drives the rack 21 to move upward along the outer end of the bracket 23, and the upward movement of the rack 21 drives the driving piston 20 to move upward, and the driving piston 20 moves upward so that the gas in the upper half of the storage cylinder 19 is pressed into the lifting cylinder 9 through the air pipe. Under the action of the air pressure, the lifting piston 10 moves upward along the inner wall of the lifting cylinder 9, driving the lifting rod 8 to move upward, lifting the Bluetooth headset 6, and making the Bluetooth headset 6 detach from the inner groove shell 2, completing the automatic ejection of the Bluetooth headset 6; The automatic pop-up mechanism improves the user's product experience and makes it easier and quicker to remove the Bluetooth headset 6. At the same time, the mechanical pop-up design is more stable and reliable than manual removal, reducing the risk of damage to the headset due to improper removal angle. S2, buffer and anti-wear; When the Bluetooth headset 6 needs to be put into the charging box, the headset cover 26 is first flipped upwards. The state at this time is the same as when the headset automatically pops up. The Bluetooth headset 6 is placed in the inner groove shell 2, and the headset cover 26 is closed. The headset cover 26 drives the tooth plate 25 to rotate downward, and the tooth plate 25 drives the gear 22 located in the middle position of the transmission shaft 24 to rotate. At the same time, the gears 22 at both ends of the transmission shaft 24 rotate together, and the gear 22 drives the rack 21 to move downward along the bracket 23. The rack 21 moves downward to make the driving piston 20 move downward along the inner wall of the storage cylinder 19. At this time, the upper half of the storage cylinder 19 draws the gas in the lifting cylinder 9 back into the storage cylinder 19, and the lifting rod 8 returns to the initial position, and the headset falls. At the same time, the driving piston 20 presses the gas in the lower half of the storage cylinder 19 into the buffer cavity 4 through the pipeline, so that the micro airbag 5 is filled with gas and is in a saturated state, and is in close contact with the Bluetooth headset 6 to prevent wear caused by the gap between the Bluetooth headset 6 and the inner groove shell 2 during walking; The buffer and anti-wear design prolongs the service life of the earphones and the charging box. The design of the micro airbag 5 not only provides good protection for the Bluetooth earphones 6, but also prevents the earphones from shaking in the box, thereby reducing noise and wear and tear and improving the overall texture of the product. S3, contact protection; During the long-term use of the earphones, an oxide layer will be generated on the surface of the metal contact 7 in the earphone box, resulting in poor charging, unstable connection, and difficulty in cleaning. At this time, the microprocessor can be controlled through the mobile phone APP to clean the metal contact 7. The microprocessor controls the piezoelectric pump 18 to generate positive pressure. The positive pressure generated by the piezoelectric pump 18 is transmitted to the protective cylinder 11 through the pipeline. The air pressure causes the protective piston 12 to move upward along the inner wall of the protective cylinder 11. The movement of the protective piston 12 drives the lifting ring 13 to move upward, so that the rubber ring 14 on the lifting ring 13 contacts the metal contact 7. At this time, the microprocessor controls the piezoelectric pump 18 to stop generating positive pressure. The compressed gas in the upper part of the protective cylinder 11 causes the protective piston 12 to return to the initial position, and the rubber ring 14 also returns to the initial position. At this time, the piezoelectric pump 18 is controlled to generate positive pressure, and this reciprocating cycle causes the rubber ring 14 to rub against the oxide layer on the metal contact 7 to remove the oxide layer; Automatic cleaning of the oxide layer of the metal contact 7 improves the safety, reliability and stability of charging, which not only extends the service life of the product, but also reduces the trouble of users manually cleaning the contacts, thereby improving the user experience. At the same time, maintenance is more convenient and intelligent through mobile phone APP control.

[0027] S4, heat dissipation and self-cleaning; When the Bluetooth headset 6 is charged, the piezoelectric pump 18 can be controlled to generate positive pressure. The positive pressure generated by the piezoelectric pump 18 enters the air tube 27 through the air pipe. When the gas passes through the impeller 29, the impeller 29 is driven to rotate. The rotation of the impeller 29 drives the soft brush 28 to rotate. The rotation of the soft brush 28 can clean out the dust and stains at the earphone of the Bluetooth headset 6 to prevent excessive accumulation in the earphone and cause blockage. At the same time, the airflow carries the dust through the gap between the inner tank shell 2 and the Bluetooth headset 6, passes through the bottom of the inner tank shell 2 and enters the dust collecting cavity 17. At the same time, the dust at the bottom of the Bluetooth headset 6 can also be taken away. The flowing airflow can also perform all-round heat dissipation on the Bluetooth headset 6. The heat dissipation and self-cleaning design not only keeps the Bluetooth headset 6 clean and extends its service life, but also effectively prevents the sound quality from being degraded due to earphone blockage. At the same time, the all-round heat dissipation function can effectively prevent overheating during charging, improve charging efficiency and safety, and reduce the frequency of manual cleaning of the headset by users. S5, overheat protection; During the charging process, due to oxidation or poor contact of the metal contact 7, the current is too large, causing serious heating of the battery. At this time, when the temperature sensor detects abnormal temperature, the microprocessor will control the piezoelectric pump 18 to generate positive pressure, and the positive pressure enters the lower half of the storage cylinder 19 through the pipeline. The positive pressure gas causes the driving piston 20 to move upward along the inner wall of the storage cylinder 19, and the storage cylinder 19 pushes the rack 21 to move upward along the bracket 23. The rack 21 drives the gear 22 to rotate, and the gear 22 drives the gear piece 25 to rotate upward, forcing the earphone cover 26 to pop open. At the same time, the positive pressure gas in the storage cylinder 19 enters the lifting cylinder 9 through the air pipe, pushing the lifting piston 10 to move upward, and the lifting piston 10 moves upward to drive the lifting rod 8 to move upward, forcing the Bluetooth headset 6 to pop out, so that the Bluetooth headset 6 is disconnected from the metal contact 7, and charging stops, thereby achieving the purpose of overheating protection. The overheat protection mechanism can automatically disconnect the charging connection when abnormal temperature is detected, effectively preventing battery damage or safety accidents caused by overheating. At the same time, the design of forced earphone ejection can quickly reduce the temperature and protect user safety. This protection measure improves the safety performance of the product and enhances the user's sense of security.

[0028] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
