[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0016] Please see Figure 1-5 The present invention provides the following technical solution: a Bluetooth headset wireless charging device, including a base 1, a receiving coil 4 installed inside the base 1, a battery board 5 electrically connected to the top of the receiving coil 4, a rectifier 6 electrically connected to one side of the battery board 5, a charging interface 7 fixedly provided on the top of the base 1, a heat dissipation component 2 installed on the top of the base 1, and a fixing component 3 fixedly installed on the bottom of the base 1. The heat dissipation assembly 2 includes a support plate 21, which is fixedly disposed in the middle of the top surface of the base 1. An anti-slip block 25 is fixedly disposed on the top surface of the support plate 21. A cavity 23 is opened inside the support plate 21. An air outlet 24 is opened on the outer surface of the support plate 21. A fan 26 is fixedly installed on one side of the support plate 21. A filter assembly 27 is installed at the air inlet end of the fan 26. An air guide pipe 22 is provided between the fan 26 and the support plate 21.

[0017] By adopting the above technical solution, when using the heat dissipation component 2, the Bluetooth headset is first placed on the surface of the support plate 21 and charged through the charging port 7. The anti-slip block 25 can prevent the Bluetooth headset from sliding. When the Bluetooth headset is charging and the temperature is high, the fan 26 is turned on. The fan 26 draws external air into the air duct 22, where impurities in the air are filtered by the filter component 27. The air then enters the cavity 23 and is discharged through the air outlet 24. The flowing air carries away the heat of the Bluetooth headset when it passes through it. At the same time, the air outlet 24 at the bottom can dissipate heat from the surface of the base 1. The design of multiple air outlets 24 can expand the heat dissipation area and further improve the heat dissipation effect.

[0018] Specifically, air guide grooves are provided at both ends of the outer surface of the bearing plate 21.

[0019] By adopting the above technical solution, the air guide groove facilitates the discharge of hot air, accelerates the airflow speed, and helps to improve the heat dissipation effect.

[0020] Specifically, the filter assembly 27 includes a mounting base 272, which is fixedly mounted on one side of the top surface of the base 1. A limiting groove 271 is provided on the inner side of the mounting base 272, and a filter plate 274 is pulled out inside the limiting groove 271. A pull plate 275 is fixedly connected to the top of the filter plate 274. A sealing ring 273 is provided on the side surface of the mounting base 272 near the fan 26.

[0021] By adopting the above technical solution, when the fan 26 is running, the filter plate 274 can filter impurities in the air, preventing impurities from entering the air duct 22. When the filter plate 274 needs to be cleaned and replaced, the pull plate 275 can be pulled out to remove the filter plate 274. After replacement, the filter plate 274 can be inserted into the limiting groove 271 through the pull plate 275 to complete the cleaning of the filter plate 274, thus improving the practicality of the component.

[0022] Specifically, a mounting block is fixedly installed on one side of the bottom of the mounting base 272, and an ear plate is installed on the top of the mounting block.

[0023] By adopting the above technical solution, the mounting block can facilitate the installation of the component in a suitable position, improving installation efficiency. The ear plate and the sealing ring 273 cooperate with each other to improve the sealing performance between the filter component 27 and the fan 26, preventing external impurities from entering the air duct 22.

[0024] In this embodiment, when using the heat dissipation component 2, the Bluetooth headset is first placed on the surface of the support plate 21 and charged through the charging port 7. The anti-slip block 25 prevents the Bluetooth headset from sliding. When the Bluetooth headset reaches a high charging temperature, the fan 26 is activated. The fan 26 draws external air into the air duct 22, where impurities are filtered by the filter component 27. The air then enters the cavity 23 and is discharged through the air outlet 24. The flowing air carries away the heat from the Bluetooth headset as it passes through it. Simultaneously, the air outlet 24 at the bottom dissipates heat from the surface of the base 1. The design of multiple air outlets 24 increases the heat dissipation area and further improves the heat dissipation effect. The air duct facilitates the discharge of hot air. The fast airflow speed is beneficial to improving heat dissipation. When the fan 26 is running, the filter plate 274 can filter impurities in the air, preventing them from entering the air duct 22. When the filter plate 274 needs to be cleaned or replaced, the pull plate 275 can be pulled out to remove the filter plate 274. After replacement, the filter plate 274 can be inserted into the limiting groove 271 through the pull plate 275 to complete the cleaning of the filter plate 274, thus improving the practicality of the component. The mounting block makes it easy to install the component in a suitable position, improving installation efficiency. The ear plate and the sealing ring 273 cooperate with each other to improve the sealing performance between the filter component 27 and the fan 26, preventing external impurities from entering the air duct 22. Example

[0025] The difference between this embodiment and embodiment 1 is that, specifically, the fixing component 3 includes a fixing seat 31, which is fixedly disposed on the bottom surface of the base 1. A bidirectional screw 36 is rotatably disposed on the inner side of the fixing seat 31. A threaded block 34 is threadedly connected to the surface of the bidirectional screw 36. A side plate 32 is fixedly connected to the bottom surface of the threaded block 34. Side blocks 33 are fixedly connected to the inner sides of both ends of the side plate 32. A soft pad 35 is disposed on the inner surface of the side plate 32.

[0026] By adopting the above technical solution, when using the fixing component 3, firstly, the component is placed on top of the wireless charging base. Then, the handwheel drives the bidirectional screw 36 to rotate, and further drives the side plates 32 to move closer to each other through the threaded block 34, until the side plates 32 on both sides clamp the two sides of the wireless charging base, thereby completing the fixing of the base 1. This ensures that the position of the wireless charging base and the receiving coil 4 remains fixed during charging, avoiding the problem of charging pause due to positional displacement, and improving the stability of the device.

[0027] Specifically, a guide block is fixed to the top of the side plate 32, and a guide groove is provided on the bottom surface of the fixed seat 31.

[0028] By adopting the above technical solution, when the side plate 32 moves, the guide block slides synchronously inside the guide groove, which can improve the stability of the side plate 32 movement.

[0029] Specifically, a handwheel is fixed to the outer end of the double-ended screw 36, and a bearing is installed at the end of the double-ended screw 36 away from the handwheel.

[0030] By adopting the above technical solution, the handwheel design facilitates the operation of the bidirectional screw 36, simplifying the operation process. The bearing can limit one end of the bidirectional screw 36, improving the stability of the rotation of the bidirectional screw 36.

[0031] In this embodiment, when using the fixing component 3, firstly, the component is placed on top of the wireless charging base. Then, the handwheel drives the bidirectional screw 36 to rotate, and the threaded block 34 drives the side plates 32 to move closer to each other until the side plates 32 clamp the two sides of the wireless charging base, thereby fixing the base 1. This ensures that the position of the wireless charging base and the receiving coil 4 remains fixed during charging, avoiding the problem of charging pause due to positional displacement, and improving the stability of the device. When the side plates 32 move, the guide block slides synchronously inside the guide groove, which can improve the stability of the side plate 32 movement. The handwheel design makes it easy for operators to operate the bidirectional screw 36, simplifying the operation process. The bearing can limit one end of the bidirectional screw 36, improving the stability of the rotation of the bidirectional screw 36.

[0032] The structure and operating principle of the receiving coil 4, battery plate 5, rectifier 6 and charging interface 7 in this utility model have been disclosed in a Bluetooth headset wireless charging device disclosed in Chinese Patent Publication No. CN222464785U.

[0033] The working principle and usage process of this utility model are as follows: When using the heat dissipation component 2, first place the Bluetooth headset on the surface of the support plate 21 and charge it through the charging interface 7. The anti-slip block 25 can prevent the Bluetooth headset from sliding. When the Bluetooth headset's charging temperature is high, the fan 26 is activated. The fan 26 draws external air into the air duct 22, where impurities in the air are filtered by the filter component 27. The air then enters the cavity 23 and is discharged through the air outlet 24. The flowing air carries away the heat from the Bluetooth headset as it passes through it. At the same time, the air outlet 24 at the bottom can dissipate heat from the surface of the base 1. The design of multiple air outlets 24 can expand the heat dissipation area and further improve the heat dissipation effect. The air duct facilitates the exhaust of hot air. The airflow speed is increased, which is beneficial to improving the heat dissipation effect. When the fan 26 is running, the filter plate 274 can filter impurities in the air and prevent them from entering the air duct 22. When the filter plate 274 needs to be cleaned or replaced, the pull plate 275 can be pulled out to remove the filter plate 274. After replacement, the filter plate 274 can be inserted into the limiting groove 271 through the pull plate 275 to complete the cleaning of the filter plate 274, which improves the practicality of the component. The mounting block can make it easy to install the component in a suitable position, which improves the installation efficiency. The ear plate and the sealing ring 273 cooperate with each other to improve the sealing performance between the filter component 27 and the fan 26, preventing external impurities from entering the air duct 22. When using the fixing component 3, first, place the component on top of the wireless charging base. Then, drive the bidirectional screw 36 to rotate via the handwheel. Further, drive the side plates 32 to move closer together via the threaded block 34 until the side plates 32 clamp the two sides of the wireless charging base, thus fixing the base 1. This ensures that the position of the wireless charging base and the receiving coil 4 remains fixed during charging, avoiding the problem of charging pause due to positional displacement, and improving the stability of the device. When the side plates 32 move, they slide synchronously in the guide groove via the guide block, which can improve the stability of the side plate 32 movement. The handwheel design makes it easy for operators to operate the bidirectional screw 36, simplifying the operation process. The bearing can limit one end of the bidirectional screw 36, improving the stability of the rotation of the bidirectional screw 36.
