Description

Technical Field

[0001] This utility model relates to the field of heat dissipation structure technology, and in particular to a heat dissipation structure for an earphone charging case. Background Technology

[0002] Utility model CN218526420U discloses an earphone charging case with a heat dissipation structure, belonging to the technical field of earphone charging cases. It includes a case body with a hinged lid, a slot for holding wireless earphones, and an internal mounting slot for mounting a rechargeable battery. An air inlet communicating with the mounting slot is through-hole in the case body, and a fan is mounted through the air inlet. An exhaust vent is also provided through the mounting slot. This earphone charging case with a heat dissipation structure allows outside air to enter the mounting slot through the air inlet when the fan is activated, thus cooling the rechargeable battery. Air inside the mounting slot is then exhausted through the air outlet, accelerating the air exchange rate within the mounting slot and achieving rapid heat dissipation for the rechargeable battery, thereby extending its lifespan.

[0003] After searching, it was found that the existing technology has certain defects. As the external airflow enters from the air inlet and exits from the air outlet, the heat carried by the airflow gradually weakens, resulting in the heat dissipation effect of the part of the charging battery near the air outlet being weaker than that near the air inlet. The heat dissipation effect is uneven. In addition, the earphone charging case itself is small in size, and the first filter at the air inlet is even smaller. It is inconvenient to install and remove the first filter using bolts smaller than the size of the first filter. Therefore, a heat dissipation structure for the earphone charging case is needed to meet people's needs. Utility Model Content

[0004] The purpose of this invention is to provide a heat dissipation structure for an earphone charging case to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a heat dissipation structure for an earphone charging case, comprising an earphone charging case, wherein a battery compartment is provided inside the earphone charging case, and air inlets and outlets are respectively provided on both sides. A cooling fan is provided in the air inlet, and a first filter cylinder and a second filter cylinder are threadedly connected to the air inlet and the air outlet, respectively. Both the first filter cylinder and the second filter cylinder are cylindrical structures, and one end located on the outside of the earphone charging case is closed and has filter holes. Partitions are provided on both sides of the battery compartment along its length, and a rechargeable battery is arranged between the two partitions. A gap is maintained between the partitions and the side wall of the battery compartment. The end of the partition near the air outlet is sealed and connected to the end of the battery compartment. The top and bottom ends of the partition are connected to the top and bottom ends of the battery compartment. The end of the partition near the air inlet extends obliquely to the center near the air inlet. Several through holes are provided on both partitions, and the several through holes are arranged along the length of the battery compartment.

[0006] Preferably, the inner walls of the air inlet and air outlet are provided with first threaded holes, and the outer walls of the first filter cylinder and the second filter cylinder are provided with first threads, which match the first threaded holes.

[0007] Preferably, a first positioning ring is provided on the inner wall of both the air inlet and the air outlet, and the two first positioning rings are in contact with the outer side of one end of the opening of the first filter cylinder and the second filter cylinder, respectively.

[0008] Preferably, the first filter cartridge is filled with a sponge, and a mesh is threadedly connected to the open end of the first filter cartridge, with the sponge arranged between the mesh and the closed end of the first filter cartridge.

[0009] Preferably, a second threaded hole is provided on the inner wall of the opening end of the first filter cylinder, and a second thread is provided on the outer wall of the mesh, the second thread matching the second threaded hole.

[0010] Preferably, a second positioning ring is provided inside the opening end of the first filter cylinder, and the second positioning ring is arranged between the mesh and the sponge.

[0011] The beneficial effects of this utility model are: In this invention, the first and second filter cylinders are connected by internal threads in the air inlet and air outlet, respectively, which enables independent assembly and disassembly of the first and second filter cylinders. This makes the assembly and disassembly process more convenient, and the cleaning can be completed without the use of tools.

[0012] In this invention, the combination of partitions and through holes allows the cooling fan to deliver outside air through the air inlet. The two partitions then divide the airflow into three streams: one stream flows directly along the length of the battery compartment, while the other two streams are discharged through the through holes due to the isolation effect of the partitions. This delivers air to different parts of the rechargeable battery, effectively preventing uneven heat dissipation. Attached Figure Description

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Reference Figure 1-5 A heat dissipation structure for an earphone charging case includes an earphone charging case 1, a battery compartment 2 inside the earphone charging case 1, and air inlets 3 and air outlets 4 on both sides. A cooling fan 5 is installed in the air inlet 3. A first filter cylinder 6 and a second filter cylinder 7 are threadedly connected to the air inlet 3 and the air outlet 4, respectively. Both the first filter cylinder 6 and the second filter cylinder 7 are cylindrical structures, and their ends on the outside of the earphone charging case 1 are closed and have filter holes. Partitions 8 are provided on both sides of the battery compartment 2 along its length. The rechargeable battery is arranged between the two partitions 8. A gap is maintained between the partitions 8 and the side wall of the battery compartment 2. The end of the partition 8 near the air outlet 4 is sealed to the end of the battery compartment 2. The top and bottom ends of the partition 8 are connected to the top and bottom ends of the battery compartment 2. The end of the partition 8 near the air inlet 3 extends at an incline to the center near the air inlet 3. Several through holes 9 are provided on both partitions 8, and the several through holes 9 are arranged along the length of the battery compartment 2.

[0017] By connecting the first filter cartridge 6 and the second filter cartridge 7 with internal threads at the air inlet 3 and air outlet 4 respectively, the first filter cartridge 6 and the second filter cartridge 7 can be independently disassembled and assembled, making the disassembly and assembly process more convenient and allowing for cleaning without the need for tools. Through the cooperation of the partition 8 and the through hole 9, after the cooling fan 5 sends outside air into the air inlet 3, the two partitions 8 divide the airflow into three streams. One stream flows directly along the length of the battery compartment 2, dissipating heat from the rechargeable battery from the air inlet 3 to the air outlet 4. The other two streams, through the isolation effect of the partition 8, flow from the gap between the partition 8 and the battery compartment 2 and are discharged through the through hole 9, dissipating heat from different parts of the rechargeable battery, and finally being discharged through the air outlet 4. Compared with the existing technology, the diversion effect maintains the temperature of the initial airflow, thereby effectively avoiding the problem of uneven heat dissipation.

[0018] Specifically, in this embodiment, the inner walls of the air inlet 3 and the air outlet 4 are provided with first threaded holes 10, and the outer walls of the first filter cylinder 6 and the second filter cylinder 7 are provided with first threads 11. The first threads 11 match the first threaded holes 10, thereby realizing the installation and disassembly of the first filter cylinder 6 in the air inlet 3 and the second filter cylinder 7 in the air outlet 4, as well as the integrated effect after installation.

[0019] Specifically, in this embodiment, a first positioning ring 12 is provided on the inner wall of both the air inlet 3 and the air outlet 4. The two first positioning rings 12 are in contact with the outer side of the opening of the first filter cylinder 6 and the second filter cylinder 7, respectively, to provide positioning for the first filter cylinder 6 and the second filter cylinder 7 after installation, and to prevent them from being screwed in too deeply, which would make them inconvenient to remove.

[0020] Specifically, in this embodiment, the first filter cylinder 6 is filled with a sponge 13, and the open end of the first filter cylinder 6 is internally threaded with a mesh 14. The sponge 13 is arranged between the mesh 14 and the closed end of the first filter cylinder 6. The sponge 13 further improves the dustproof effect at the air inlet 3, and the mesh 14 ensures gas flow and provides positioning for the sponge 13 after filling.

[0021] Specifically, in this embodiment, a second threaded hole 15 is provided on the inner wall of the opening end of the first filter cylinder 6, and a second thread 16 is provided on the outer wall of the mesh 14. The second thread 16 matches the second threaded hole 15, and the detachable effect of the mesh 14 facilitates the replacement and cleaning of the sponge 13.

[0022] Specifically, in this embodiment, a second positioning ring 17 is provided inside the opening end of the first filter cylinder 6. The second positioning ring 17 is arranged between the partition 14 and the sponge 13 to provide installation positioning for the partition 14, prevent it from being screwed in too deeply and making it inconvenient to remove, and avoid the problem of reduced gas flow effect caused by the compression of the sponge 13 by the partition 14.

[0023] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
