[0026] The following further describes the present invention in detail with reference to the accompanying drawings. The technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0027] Such as Figures 1-4As shown in the figure, a Bluetooth headset case with multiple charging methods includes a placement case 2 and a case cover 3. An earphone slot 8 for placing a Bluetooth headset 7 is provided inside the placement case 2 and the case cover 3. A bottom case 1 is provided at the bottom of the placement case 2. A charging battery panel 14 and a reciprocating chamber 16 are provided inside the bottom case 1. A reciprocating valve block 17 that moves back and forth along the reciprocating chamber 16 is installed in the reciprocating chamber 16. An air inlet chamber 19 is provided at each end of the reciprocating chamber 16. An air inlet valve block 21 and an air inlet spring 22 are installed in each air inlet chamber 19. The air inlet spring 22 pushes the air inlet valve block 21 to fit and seal with the air inlet 20 of the air inlet chamber 19. A connection hole 27 is provided between the air inlet chamber 19 and the reciprocating chamber 16. The side wall of the connection hole 27 is connected to an exhaust groove 23. The other ends of the two exhaust grooves 23 are respectively connected to two air inlet valve ports 24 of an exhaust valve 24. The exhaust valve port of the exhaust valve 24 is connected to one end of an air duct 25. An impeller 26 is installed in the air duct 25. The impeller 26 is connected to a micro generator 32. The micro generator 32 is electrically connected to the charging battery panel 14. The other end of the air duct 25 is connected to an exhaust hole 5. The exhaust hole 5 is communicated with the outside. The micro generator 32 is connected to a turntable 4 outside the bottom case 1 through a connection structure 33.

[0028] Further, as Figure 6 and Figure 7 shown, the connection structure 33 includes a connection block 34, a connection seat 35 and a connection groove 36. The connection block 34 is fixedly connected to the rotating shaft of the impeller 26. The connection seat 35 is fixedly connected to the rotating shaft of the turntable 4. The connection groove 36 is provided on the connection seat 35. The connection block 34 and the connection groove 36 are of a regular polygon structure, preferably a square structure. Both the connection block 34 and the connection seat 35 are located in a connection chamber. A limiting shoulder is provided on the connection seat 35. Press or pull the turntable 4 from the outside to make the connection block 34 cooperate with or disengage from the connection groove 36.

[0029] Further, as Figure 3 and Figure 4 shown, the exhaust valve 24 includes an exhaust valve block 28, an exhaust spring 29, a guiding convex rib 30 and an exhaust valve chamber 31. The number of the exhaust valve blocks 28 is two. Two exhaust valves 28 and an exhaust spring 29 are installed in the exhaust valve chamber 31. The two ends of the exhaust spring 29 push the two exhaust valves 28 to respectively fit and seal with the air inlet valve ports at both ends of the exhaust valve chamber 31. The two air inlet valve ports are respectively connected to the connection holes 27 at both ends of the reciprocating chamber 16 through an exhaust groove 23. Multiple spaced convex ribs 30 are provided on the side wall of the exhaust valve chamber 31, forming a track for the movement of the exhaust valve 28 in the middle. The middle position of the exhaust valve chamber 31 is communicated with the air duct 25.

[0030] Furthermore, the direction in which the reciprocating valve block 17 moves within the reciprocating chamber 16 is perpendicular to the direction in which the exhaust valve block 28 moves within the exhaust valve chamber 31. When the shaking bottom box 1 is charging, the discharge valve block 28 within the exhaust valve 24 is not affected by the shaking, ensuring the reliability of its operation.

[0031] Furthermore, on both sides of the upper end of the bottom box 1, there are insertion blocks 9. The bottom of the placement box 2 is provided with slots that cooperate with the insertion blocks 9. On the side wall and top of the insertion block 9, there are respectively a conductive contact block one 10 and a magnetic attraction block one 12. Corresponding to these within the slots, there are a conductive block two 11 and a magnetic attraction block two 13.

[0032] Furthermore, on the side wall of the bottom box 1, there is a charging interface 15. The charging interface 15 is electrically connected to the charging battery panel 14 through a wire. It is also possible to directly charge the charging interface 15 using a charger.

[0033] Furthermore, at both ends of the reciprocating block 17, there are protective pads 18. The protective pads 18 are made of rubber material. The reciprocating block 17 is made of a metal block with a relatively large density. The protective pads 18 protect the reciprocating block 17 and the reciprocating chamber 16. Through shaking, the metal block moves back and forth within the reciprocating chamber 16, starting to compress the gas. The compressed gas enters the air duct 25 through the exhaust valve 24, operates on the impeller 26, and drives the micro - generator 18 to generate electricity.

[0034] Furthermore, one side of the box cover 3 is hinged to the placement box 2, and the other side of the box cover 3 is connected to the placement box 2 through a magnetic attraction structure. The magnetic attraction structure is to set a magnet block on each of the box cover 3 and the placement box 2, and they are attracted and closed through the magnet blocks.

[0035] Furthermore, on the outer wall of the magnetic attraction side of the box cover 3 and the placement box 2, there is an in - concave flip - up groove 6. Through the design of the flip - up groove 6, it is convenient to open the box cover 3.

[0036] Working principle: When choosing rotational charging, by pressing the turntable 4 to move it inward, the connecting groove 36 on the connecting seat 35 cooperates with the connecting block 34, and rotating the turntable 4 drives the impeller 26 and the micro generator 32 to rotate and generate electricity to charge the charging battery panel 14. When choosing shaking charging, pull out the turntable 4 outward to disconnect it from the micro generator 32, shake the bottom box 1, and the reciprocating block 17 reciprocates in the reciprocating cavity 16. When the reciprocating block 17 moves to the left, the intake valve block 21 in the left intake cavity 19 will fit and seal, while the intake valve block 21 on the right will compress the exhaust spring 29 due to inertia and internal negative pressure, and the external air enters the right end of the reciprocating cavity 16 to balance the internal and external air pressures. The air at the left end of the reciprocating cavity 16 is compressed, passes through the exhaust groove 23 to push open the exhaust valve block 28 corresponding to the exhaust valve 24 (the exhaust valve block on the other side is tightly closed), and enters the exhaust valve cavity 31 and the air duct 25, and the airflow drives the impeller 26 to rotate and generate electricity; when the reciprocating block 17 moves to the right, the principle is the same as when moving to the left. At the same time, we can also choose to directly charge by connecting the charger to the charging interface 15 to meet the charging requirements in different scenarios.

[0037] This specific embodiment is only an explanation of the present invention, and it is not a limitation of the present invention. After reading this specification, those skilled in the art can make modifications to this embodiment without creative contributions as needed, but as long as it is within the scope of the claims of the present invention, it is protected by the patent law.
