Among them, head-mounted Bluetooth headsets can provide stronger transmission stability and larger battery capacity, which can meet more needs of contemporary young people.

[0003] The head-mounted Bluetooth headsets currently on the market do not have the effect of heat dissipation. Therefore, after wearing for a long time, the ear-covering foam will gather a lot of heat due to the body temperature, affecting the wearing comfort, especially in hot weather. In addition, due to the setting of the ear-hanging foam, the ears will be stuffy inside the foam when wearing the headset. Long-term closure may cause ear diseases.

[0004] Therefore, how to provide a Bluetooth headset with a heat dissipation structure is a problem that those skilled in the art need to solve urgently. Summary of the invention

The fan blade is rotatably arranged inside the wind cover. The wind cover is fixed to the bottom of the protective shell, and one side of the wind cover is aligned with the water storage box. The air inlet channel is opened between the wind cover and the protective shell.

[0009] Furthermore, isolation sheets are fixed to the upper and lower sides of the inner surface of the buckle sleeve respectively, and the two groups of moisture-absorbing cotton are separated from each other inside the buckle sleeve by the isolation sheets.

[0010] Furthermore, the buckle sleeve is made of silicone and the connection end ring is made of copper.

[0011] Furthermore, a concave groove is provided at a position of the connecting end ring close to the protective shell, and the size of the concave groove matches the size of the convex ring slide rail, and the snap-fit ​​sleeve is rotatably arranged on one side of the protective shell through the connecting end ring and the convex ring slide rail.

[0012] Furthermore, one side of the water storage box is also fixedly connected to a heat dissipation fin, and the heat dissipation fin is aligned with the position of the air hood port.

[0013] Furthermore, the fan blades are rotatably arranged inside the wind shield by a micro motor, and the micro motor is fixed on one side of the wind shield.

[0014] Furthermore, the micro motor is electrically connected to the speaker assembly, and a motor driver is provided inside the micro motor.

[0015] Furthermore, the top opening position of the air inlet channel is aligned with the speaker assembly, and the wind shield is connected to a side space of the speaker assembly through the air inlet channel.

[0019] The present invention fixes water storage boxes on the upper and lower sides of the buckle sleeve respectively, and the buckle sleeve is connected to the upper and lower water storage boxes through the moisture-absorbing cotton and the moisture-absorbing rod. In normal use, the water in the water storage box at the top of the buckle sleeve will be absorbed by the moisture-absorbing rod and the moisture-absorbing cotton, and the water will fall slowly inside the buckle sleeve under the action of gravity until the moisture-absorbing rod at the bottom of the moisture-absorbing cotton absorbs it to the water storage box below for collection.

[0031] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0032] refer to Figure 1-Figure 6 , including a ring-wearing rod 1 and two sets of earphone housings 3, the two sets of earphone housings 3 are movably connected to the left and right sides of the bottom of the ring-wearing rod 1 through the adjustment end rod 2, the earphone housing 3 includes a protective shell 31 and a convex ring slide rail 32 fixed on one side of the protective shell 31, the protective shell 31 is fixedly connected to the speaker assembly 4, and a self-cooling mechanism 5 is arranged on one side of the protective shell 31 through the convex ring slide rail 32;

[0033] The self-cooling mechanism 5 includes a buckle sleeve 51 and a connecting end ring 52, wherein the connecting end ring 52 is fixed to one side of the buckle sleeve 51, and the connecting end ring 52 is fixed to the upper and lower sides of the buckle sleeve 51 respectively, and two groups of moisture-absorbing cotton 54 are arranged inside the buckle sleeve 51, and moisture-absorbing rods 55 are arranged at the upper and lower ends of the moisture-absorbing cotton 54 near the water storage box 53, and the moisture-absorbing rods 55 are located inside the water storage box 53;

[0034] The bottom of the protective shell 31 is also fixedly connected to the auxiliary cooling mechanism 6, which includes a fan blade 63 and an air inlet channel 65. The fan blade 63 is rotatably arranged inside the wind cover 62. The wind cover 62 is fixed to the bottom of the protective shell 31, and one side of the wind cover 62 is aligned with the water storage box 53. The air inlet channel 65 is opened between the wind cover 62 and the protective shell 31.

[0035] In this embodiment, the protective shell 31 and the convex ring slide rail 32 are integrally formed as the earphone housing 3, which are movably arranged on both sides of the bottom of the ring rod 1 by adjusting the end rod 2, so as to meet the adjustment wearing requirements of the normal head-mounted Bluetooth headset, and the buckle sleeve 51 is rotatably arranged on the convex ring slide rail 32 by connecting the end ring 52, and the buckle sleeve 51 provides the normal need to fit the skin around the ear;

[0036] The water storage box 53 fixed on the upper and lower sides of the buckle sleeve 51 provides a normal water storage effect. Under normal circumstances, the water inside the water storage box 53 will be absorbed by the moisture absorption rod 55. The moisture absorption rod 55 is fixed to the moisture absorption cotton 54, so that the moisture absorption cotton 54 can normally absorb the water inside the water storage box 53 through the moisture absorption rod 55. The water contacts the inner surface of the buckle sleeve 51, and the heat generated by the contact between the surface of the buckle sleeve 51 and the skin is absorbed. Under the action of gravity, the water is gathered again through the moisture absorption rod 55 to the water storage box 53 below the buckle sleeve 51 to achieve collection. The heat absorption effect is completed in the process, and the whole is relatively sealed. The water can use a fluorinated liquid with a stronger heat absorption effect and a higher density, so as to achieve the purpose of falling on the materials of the moisture absorption cotton 54 and the moisture absorption rod 55. The specific decision depends on the actual use occasion and will not be elaborated here.

[0037] It is worth noting that the hygroscopic cotton 54 and the hygroscopic rod 55 are hygroscopic materials. To ensure that the water can normally drip from the hygroscopic rod 55 below the hygroscopic cotton 54 into the water storage box 53, the hygroscopic cotton 54 and the hygroscopic rod 55 can be wetted first to prevent the water from staying in the hygroscopic cotton 54 and unable to move downward under the action of tension.

[0038] More specifically, after the water is gathered in the water storage box 53 below the buckle sleeve 51, since it absorbs heat in the process of falling inside the buckle sleeve 51, the fan blade 63 in the wind shield 62 can be driven to rotate by the micro motor 61, and the port of the wind shield 62 is aligned with the water storage box 53. Under the circulation of air, the surface of the water storage box 53 is cooled, and the heat of the water inside is taken away;

[0039] More specifically, during the rotation of the fan blades 63, air enters the interior near the ear through the air inlet 65, achieving air circulation at the ear position, and is blown out at the gap between the snap-fit ​​sleeve 51 and the skin, thereby preventing ear diseases caused by wearing for too long a time.

[0040] refer to Figure 3 , Figure 4 and Figure 6 The upper and lower sides of the inner surface of the buckle sleeve 51 are respectively fixed with isolation sheets 56, and the two groups of moisture-absorbing cotton 54 are separated from each other inside the buckle sleeve 51 by the isolation sheets 56. The buckle sleeve 51 is made of silicone, and the connecting end ring 52 is made of copper. A concave slide groove is provided at the position of the connecting end ring 52 close to the protective shell 31, and the size of the concave slide groove matches the size of the convex ring slide rail 32. The buckle sleeve 51 is rotatably arranged on one side of the protective shell 31 through the connecting end ring 52 and the convex ring slide rail 32.

[0041] In the present embodiment, the function of the isolation sheet 56 can effectively realize the heat absorption operation of the two groups of moisture-absorbing cottons 54 on the surfaces of both sides of the snap-fit ​​sleeve 51, respectively, to ensure that the moisture-absorbing cottons 54 can absorb moisture normally, and prevent the snap-fit ​​sleeve 51 from being unable to absorb heat on one side due to the rotation angle of the snap-fit ​​sleeve 51 affecting the falling direction of the water body. The snap-fit ​​sleeve 51 made of silicone has better sealing and protection effect than the leather used in traditional technology, and can better realize heat conduction.

[0042] refer to Figure 6 One side of the water storage box 53 is also fixedly connected to the heat dissipation fin 64, and the heat dissipation fin 64 is aligned with the port position of the wind cover 62.

[0043] In this embodiment, after the water storage box 53 has collected the water, the heat dissipation fins 64 on one side can provide an overall heat dissipation effect for the water storage box 53, thereby facilitating the cooling of the book body inside the water storage box 53, and the heat dissipation fins 64 are aligned with the wind cover 62. After the fan blades 63 inside the wind cover 62 rotate, the air flow can more effectively dissipate the heat of the water storage box 53, thereby achieving the purpose of efficient heat dissipation.

[0044] refer to Figure 4 , Figure 5 and Figure 6 The fan blade 63 is rotated by a micro motor 61 and is arranged inside the wind shield 62. The micro motor 61 is fixed to one side of the wind shield 62. The micro motor 61 is electrically connected to the speaker assembly 4, and a motor driver is arranged inside the micro motor 61.

[0045] In this embodiment, the speaker assembly 4 and the micro motor 61 are electrically connected to control the rotation speed of the micro motor 61, thereby achieving different cooling and ventilation effects. After the micro motor 61 drives the fan blades 63 to rotate, the wind flow will cause noise to a certain extent, and by controlling the rotation speed of the micro motor 61 through the motor driver and the speaker assembly 4, a noise reduction effect can be achieved to a certain extent.

[0046] refer to Figure 4 and Figure 6 The top opening of the air inlet 65 is aligned with the speaker assembly 4, and the wind shield 62 is connected to a side space of the speaker assembly 4 through the air inlet 65. An air outlet 66 is also provided at the top of the protective shell 31 near the speaker assembly 4, and the top of the air outlet 66 is connected to the outside.

[0047] In the present embodiment, the top opening of the air inlet 65 realizes the ventilation effect toward one side of the speaker assembly 4. After the air enters the inside, ventilation is realized around the ear, and the gas flows out from the gap between the snap-fit ​​sleeve 51 and the skin. In some cases, in order to ensure the quality of audio output, the skin and the snap-fit ​​sleeve 51 are tightly fitted, and the air flows out from the air outlet 66 at this time to ensure the gas circulation effect.

[0048] refer to Figure 1 The speaker assemblies 4 inside the two groups of protective shells 31 are electrically connected to each other through the ring rod 1 and the adjustment end rod 2. A control switch is set on one side of the protective shell 31, and the control switch is electrically connected to the speaker assembly 4.

[0049] In this embodiment, the control switch can be used to control the rotation speed of the micro motor 61, thereby achieving a regulating effect.

[0050] Working principle: During normal use, the earphone housing 3 on both sides below the ring rod 1 is adjusted by adjusting the end rod 2 to achieve the effect of easy wearing. During wearing, the water storage box 53 above the snap-fit ​​sleeve 51 in the self-cooling mechanism 5 can store water, and the desiccant rod 55 can normally absorb the water inside the water storage box 53 and absorb it into the desiccant cotton 54. The desiccant cotton 54 is located inside the snap-fit ​​sleeve 51 and is separated by an isolation sheet 56. In this way, the water flows downward in the desiccant cotton 54 under the action of gravity and contacts the surface of the snap-fit ​​sleeve 51, taking away the heat from the surface of the snap-fit ​​sleeve 51. Finally, the water drips from the desiccant rod 55 below the desiccant cotton 54 back into the water storage box 53 for collection. After the micro-motor 61 in the auxiliary cooling mechanism 6 is driven, it can drive the wind in the wind hood 62. The blades 63 rotate, and the wind shield 62 aligns with the heat dissipation fins 64 on one side of the water storage box 53 to achieve air circulation. At this time, the water storage box 53 is cooled, which is convenient for cooling the internal water body. An air inlet 65 is provided between the wind shield 62 and the protective shell 31. Air enters the protective shell 31 through the air inlet 65 to the side close to the speaker assembly 4 to achieve air circulation around the ear. The gas flows out from the air outlet 66 opened on the top of the protective shell 31, thereby preventing the occurrence of ear diseases caused by long-term closed wearing, and also facilitating the heat dissipation effect. Finally, by pulling open the entire earphone shell 3 and rotating the snap-fit ​​sleeve 51 as a whole through the rotation effect between the connecting end ring 52 and the convex ring slide rail 32, the downward movement operation of the water body in the water storage box 53 is re-realized, and the overall operation is similar to the principle of an hourglass.

[0051] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
