[0002] Bluetooth stereo headset is a wireless headset based on wireless communication system, which transmits the encoded voice signal to the headset through Bluetooth communication technology. Because Bluetooth headset does not require complicated wiring, it is popular among the masses.

[0003] Traditional Bluetooth stereo headsets are usually head-mounted headphones. When worn, the headphones tightly wrap the two ears to achieve a better stereo surround effect of sound. However, when the weather is hot, long-term wearing will cause heat in the ears and even sweating, which will greatly affect its comfort. Therefore, a Bluetooth stereo headset is needed to solve the above problem. Utility Model Content

[0004] The purpose of the utility model is to provide a Bluetooth stereo headset to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a Bluetooth stereo headset, comprising two headset bodies, the two headset bodies are commonly provided with a headset headband, the adjacent sides of the two headset bodies are provided with ear-sticking parts, the two ear-sticking parts are provided with ventilation grooves, the two headset bodies are fixedly connected with slip rings through fixed blocks, each of the slip rings is slidably connected with two sliding sleeves, one side of each sliding sleeve is fixedly connected with a covering block, each covering block is slidably arranged on the outside of the corresponding headset body, one side of the two headset bodies is rotatably connected with a worm gear, one side of the two sliding sleeves on the same side are commonly fixedly connected with a connecting arm, the connecting arm is fixedly connected to the worm gear, one side of each headset body is fixedly connected with two connecting blocks, a worm is rotatably connected between the two connecting blocks, the worm gear is meshed with the worm gear, and a turning handle is fixedly connected to the rotating part of the bottom end of the worm gear.

[0006] By setting up ventilation slots, when the handle is turned, the worm gear will be driven to rotate by the worm, and the worm gear will drive the cover block to rotate through the transmission of the connecting arm and the sliding sleeve, so that the cover block can be separated from the cover of the ventilation slot through rotational displacement, thereby allowing the air in the ear-fitting part to circulate to the outside. During running or walking, the effect of air circulation will be further increased, so that the ear covered by the ear-fitting part can be cooled to a certain extent, ensuring a certain degree of comfort in use.

[0007] As a preferred implementation, the ventilation slots are arranged in front-to-back directions.

[0008] As a preferred implementation, the shielding block is located at the ventilation slot.

[0009] As a preferred implementation, the worm is vertically located on one side of the worm wheel.

[0010] As a preferred embodiment, the shielding block and the fixing block are arranged on different surfaces.

[0011] As a preferred embodiment, the headphone headband is a retractable headband.

[0012] By setting a vertical worm gear, the handle can be easily rotated while ensuring a certain design aesthetic. The headphone headband can be extended to adjust its wearing size, thereby ensuring a wide range of users.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The utility model provides ventilation slots. When the handle is turned, the worm gear is driven to rotate by the worm, and the worm gear is driven to rotate the covering block by the transmission of the connecting arm and the sliding sleeve, so that the covering block can be separated from the cover of the ventilation slot by rotational displacement, thereby allowing the air in the ear-fitting portion to circulate to the outside. During running or walking, the effect of air circulation is further increased, so that the ear covered by the ear-fitting portion can be cooled to a certain extent, thereby ensuring a certain degree of comfort in use.

[0015] The utility model can facilitate the rotation of the handle by arranging a vertical worm, while ensuring a certain aesthetic design. The headphone head ring can be extended to adjust its wearing size, thereby ensuring a wide range of users. BRIEF DESCRIPTION OF THE DRAWINGS
