Technical Field

[0001] This utility model relates to the technical field of Bluetooth headsets, and in particular to a sports waterproof Bluetooth headset. Background Technology

[0002] Bluetooth headsets apply Bluetooth technology to hands-free devices, freeing users from the hassle of wires and allowing for easy and convenient calls in various ways. Since their introduction, Bluetooth headsets have been a valuable tool for mobile business professionals to improve efficiency. Sports Bluetooth headsets are wireless audio devices specifically designed for sports activities. They connect to mobile phones / smart devices via Bluetooth and feature anti-drop, waterproof, sweatproof, and environmental sensing capabilities, making them suitable for high-intensity activities such as running, cycling, and swimming. Therefore, a sports-grade waterproof Bluetooth headset is particularly needed.

[0003] However, most existing sports waterproof Bluetooth headsets only support splash resistance during use and cannot withstand immersion in sweat or rainwater penetration, which can lead to corrosion of internal circuits and affect the lifespan of the Bluetooth headset. Utility Model Content

[0004] The purpose of this invention is to provide a sports waterproof Bluetooth headset to solve the problem mentioned in the background art that most existing sports waterproof Bluetooth headsets only support splash resistance during use and cannot cope with sweat immersion or rain penetration, which leads to corrosion of internal circuits and affects the service life of the Bluetooth headset.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sports waterproof Bluetooth headset, comprising a headset body, the surface of which is coated with a waterproof coating, a sound outlet tube installed at one end of the headset body, an earplug connected to one end of the sound outlet tube, a flow guide groove provided on the side of the headset body near the sound outlet tube, a limit ring fixedly connected to the surface of the sound outlet tube, a connecting ring fitted onto the surface of the sound outlet tube, a spring fixedly connected to one side of the surface of the connecting ring, a charging port provided on one side of the surface of the headset body, and a waterproof mechanism provided on one side of the surface of the headset body.

[0006] Preferably, the waterproof coating is a nano-hydrophobic coating.

[0007] Preferably, the guide groove has a width of 0.5 mm and a depth of 0.3 mm, and is distributed at 2 mm intervals along the side of the shell.

[0008] Preferably, the connecting ring is fitted onto one end surface of the sound tube by a limiting ring.

[0009] Preferably, the earplug is fitted onto the surface of the connecting ring, and one end of the spring is fixedly connected to the earplug.

[0010] Preferably, the waterproof mechanism includes a mounting hole, a magnetic ring, a connecting strip, a sealing plate, a magnetic plate, and a sealing strip. The mounting hole is provided on the side of the earphone body near the charging port. A magnetic ring is fixedly connected inside the charging port. A connecting strip is fixedly connected inside the mounting hole. A sealing plate is fixedly connected to the other end of the connecting strip. A magnetic plate is fixedly connected to one side of the sealing plate. A sealing strip is fixedly connected to one side of the magnetic ring.

[0011] Preferably, the connecting band is an elastic band, the sealing plate matches the size of the charging port, and the sealing strip is made of rubber.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This sports waterproof Bluetooth headset uses a waterproof coating evenly applied to the surface of the headset body. The nano-hydrophobic coating, through a biomimetic lotus leaf structure design, forms nanoscale micropores and uneven surfaces (contact angle ≥150°), allowing droplets to roll off rather than soak in, effectively blocking water molecule penetration. The coating thickness is only 0.1-5μm, invisible to the naked eye and does not affect the device's heat dissipation or appearance design. It is suitable for protecting precision electronic components. Thus, when the waterproof coating is evenly applied to the surface of the headset body, it can prevent sweat and rainwater erosion, extending the service life of the headset body. The drainage channel quickly drains salty sweat or seawater, reducing oxidation and corrosion of metal contacts (such as the charging port), extending the service life of the headset body. At the same time, the waterproof mechanism can waterproof the charging port, preventing liquid from seeping into the charging port and affecting the service life of the headset body.

[0018] 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.

[0019] Please see Figure 1-4 This utility model provides a technical solution: a sports waterproof Bluetooth headset, including a headset body 1, the surface of the headset body 1 is coated with a waterproof coating 2, a sound outlet 3 is installed at one end of the headset body 1, an earplug 4 is installed and connected to one end of the sound outlet 3, a guide groove 5 is opened on the side of the headset body 1 near the sound outlet 3, a limit ring 6 is fixedly connected to the surface of the sound outlet 3, a connecting ring 7 is fitted and connected to the surface of the sound outlet 3, a spring 8 is fixedly connected to one side of the surface of the connecting ring 7, a charging port 9 is opened on one side of the surface of the headset body 1, and a waterproof mechanism 10 is provided on one side of the surface of the headset body 1.

[0020] Furthermore, the waterproof coating 2 is a nano-hydrophobic coating. Due to the setting of the waterproof coating 2, during use, because the waterproof coating 2 is a nano-hydrophobic coating, the nano-hydrophobic coating is designed with a biomimetic lotus leaf structure to form nanoscale micropores and uneven surfaces (contact angle ≥150°), so that droplets roll off instead of wetting, effectively blocking the penetration of water molecules. The coating thickness is only 0.1-5μm, which is invisible to the naked eye and does not affect the heat dissipation and appearance design of the device. It is suitable for the protection of precision electronic components. Thus, when the waterproof coating 2 is evenly coated on the surface of the earphone body 1, it can prevent sweat and rainwater from corroding and extend the service life of the earphone body 1.

[0021] Furthermore, the guide groove 5 has a width of 0.5mm and a depth of 0.3mm, and is distributed at 2mm intervals along the side of the shell. Through the setting of the guide groove 5, during use, the guide groove 5 guides the liquid to drain along a specific path through the V-shaped design, avoiding the accumulation of sweat and rainwater on the surface or in the gaps of the earphone body 1. The guide groove 5 can increase the liquid flow rate by 30% to 50%, significantly reducing the risk of liquid intrusion into the internal circuit. By quickly draining salty sweat or seawater, it reduces the oxidation and corrosion of metal contacts (such as charging interfaces) and extends the service life of the earphone body 1.

[0022] Furthermore, the connecting ring 7 is fitted onto one end surface of the sound tube 3 via the limiting ring 6. With the connection ring 7 in use, the earplug 4 can be fixedly installed by fitting the connecting ring 7 onto one end surface of the sound tube 3 via the limiting ring 6.

[0023] Furthermore, the earplug 4 is fitted onto the surface of the connecting ring 7, and one end of the spring 8 is fixedly connected to the earplug 4. With the setting of the spring 8, when in use, the earplug 4 can be pressed to compress and deform the spring 8 according to the ear conditions of different users. When the earplug 4 is inserted into the ear, the spring 8 rebounds and deforms based on its characteristics, so that the earplug 4 can be stably embedded in the ear and prevent the headphone body 1 from slipping off the ear when the user is exercising.

[0024] Furthermore, the waterproof mechanism 10 includes a mounting hole 1001, a magnetic ring 1002, a connecting strap 1003, a sealing plate 1004, a magnetic plate 1005, and a sealing strip 1006. A mounting hole 1001 is provided on the surface of the earphone body 1 near the charging port 9. A magnetic ring 1002 is fixedly connected inside the charging port 9. A connecting strap 1003 is fixedly connected inside the mounting hole 1001. A sealing plate 1004 is fixedly connected to the other end of the connecting strap 1003. A magnetic plate 1005 is fixedly connected to one side of the sealing plate 1004. A sealing strip 1006 is fixedly connected to one side of the magnetic ring 1002. The waterproof mechanism 10 includes a mounting hole 1001, a magnetic ring 1002, a connecting strap 1003, a sealing plate 1004, and a sealing strip 1006. With the installation of seal strip 1006 and 5, when the earphone body 1 is fully charged, the connecting strap 1003 can be bent. Since the connecting strap 1003 is an elastic band, the sealing plate 1004 can be pulled to the charging port 9. The sealing plate 1004 is then fitted into the charging port 9. Since a magnetic plate 1005 is fixedly connected to one side of the surface of the sealing plate 1004, and a magnetic ring 1002 is fixedly connected to the inside of the charging port 9, the magnetic plate 1005 and the magnetic ring 1002 are magnetically connected. Since a sealing strip 1006 is fixedly connected to one side of the surface of the magnetic ring 1002, the sealing plate 1004 and the sealing strip 1006 seal the charging port 9, preventing liquid from seeping into the earphone body 1.

[0025] Furthermore, the connecting strip 1003 is an elastic strip, the sealing plate 1004 matches the size of the charging port 9, and the sealing strip 1006 is made of rubber. With the setting of the sealing plate 1004 and the sealing strip 1006, when in use, the sealing plate 1004 and the sealing strip 1006 cooperate to seal the charging port 9, preventing liquid from seeping into the inside of the earphone body 1.

[0026] Working principle: After the earphone body 1 is fully charged, the connecting strap 1003 can be bent. Since the connecting strap 1003 is an elastic band, the sealing plate 1004 can be pulled to the charging port 9. The sealing plate 1004 is then fitted into the charging port 9. Since a magnetic plate 1005 is fixedly connected to one side of the surface of the sealing plate 1004, and a magnetic ring 1002 is fixedly connected to the inside of the charging port 9, the magnetic plate 1005 and the magnetic ring 1002 are magnetically connected. Since a sealing strip 1006 is fixedly connected to one side of the surface of the magnetic ring 1002, the sealing plate 1004 and the sealing strip 1006 seal the charging port 9, preventing liquid from seeping into the earphone body 1. Then, the earplug 4 is fixedly installed on one end of the sound tube 3 through the connecting ring 7 and the limiting ring 6. Pressing the earplug 4 compresses the spring 8, and then the earplug 4 is inserted into the user's ear. The spring 8 then returns, fixing the earplug 4 in place in the user's ear. To prevent the earphone body 1 from slipping off the ear during exercise, a uniformly coated nano-hydrophobic coating on the surface of the earphone body 1 uses a biomimetic lotus leaf structure design to form nanoscale micropores and uneven surfaces (contact angle ≥150°), allowing droplets to roll off rather than soak in, effectively blocking water molecule penetration. The coating thickness is only 0.1-5μm, invisible to the naked eye and does not affect the device's heat dissipation or appearance design, making it suitable for protecting precision electronic components. Thus, when the waterproof coating 2 is uniformly coated on the surface of the earphone body 1, it can prevent sweat and rainwater corrosion, extending the service life of the earphone body 1. At the same time, the drainage channel 5 guides liquid out along a specific path through a V-shaped design, preventing sweat and rainwater from accumulating on the surface or in the gaps of the earphone body 1. The drainage channel 5 can increase the liquid flow rate by 30% to 50%, significantly reducing the risk of liquid intrusion into the internal circuitry. By quickly draining salty sweat or seawater, it reduces the oxidation and corrosion of metal contacts (such as the charging interface), extending the service life of the earphone body 1.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
