Abstract
Description
Technical Field
[0001] This utility model relates to the field of Bluetooth headsets, specifically to Bluetooth headsets with a waterproof and dustproof structure. Background Technology
[0002] Bluetooth headsets, as portable audio devices, are widely used in sports, commuting, and outdoor scenarios. Their operating environments often involve contact with sweat, rain, or dust, thus requiring high levels of waterproof and dustproof performance for their internal electronic components. The sound outlet, as a crucial channel for sound transmission, and the battery compartment, as the power module's supporting structure, are highly interactive with the external environment. Insufficient protection can easily lead to moisture and dust intrusion, causing problems such as component corrosion, poor contact, or functional failure.
[0003] Common Bluetooth headsets often rely on a single waterproof membrane or simple sealing structure for waterproofing, which is insufficient for protecting the gaps between the sound outlet and the headset shell, as well as the connection between the battery compartment and the sealing cover. If only a regular dust filter is installed at the sound outlet, it is difficult to completely prevent liquids or small particles from entering the shell. If the connection between the battery compartment and the sealing cover uses a flat fit or a regular sealing ring, frequent opening and closing or long-term use can easily lead to deformation or misalignment of the seal, causing gaps to widen and allowing moisture and dust to enter through the connection. Utility Model Content
[0004] The purpose of this invention is to solve the above-mentioned defects and provide a Bluetooth headset with a waterproof and dustproof structure. When in use, it can seal the gap between the sealing cover and the battery compartment, solving the technical problem that the existing technology is prone to the expansion of gaps due to deformation and misalignment of the sealing component after frequent opening and closing or long-term use, allowing moisture and dust to enter through the connection.
[0005] The objective of this utility model is achieved through the following means:
[0006] A Bluetooth headset with a waterproof and dustproof structure includes a headset shell, a battery compartment at the bottom of the headset shell, a sealing cover snapped onto the outside of the headset shell, a waterproof membrane inserted inside the headset shell and the sealing cover, a dustproof mesh installed inside the sound outlet of both the headset shell and the sealing cover, a sealing cover snapped onto the bottom of the battery compartment, a battery inserted inside the battery compartment, contacts inserted inside the sealing cover, a sealing gasket affixed to the top of the sealing cover, a conical ring inserted into the lower inner wall of the sealing cover, and a main control circuit board inside the headset shell, the main control circuit board including a Bluetooth chip, a microphone, a speaker, an antenna, and related circuit components.
[0007] Furthermore, electrode holders are installed on both sides of the bottom of the battery, and pins are connected to the top sides of the contacts at positions corresponding to the electrode holders. This makes the connection between the battery and the contacts more precise and stable, reduces power supply problems caused by poor contact, and ensures the continuity of power supply to the headphones.
[0008] Furthermore, the waterproof membrane is made of polytetrafluoroethylene microporous filter membrane, and the surface of the waterproof membrane is coated with a hydrophobic nano-coating. The exterior of the waterproof membrane is connected to the inner wall of the earphone shell by adhesive. The polytetrafluoroethylene microporous filter membrane combined with the hydrophobic nano-coating can enhance the waterproof and breathable performance of the waterproof membrane. The adhesive connection makes the waterproof membrane more firmly installed, less likely to fall off, and continuously provides protection.
[0009] Furthermore, a waterproof sealing sleeve is fitted on the top of the electrode holder. The waterproof sealing sleeve is made of fluororubber material and has a nickel-chromium alloy wire mesh embedded inside. An annular sealing lip is provided at the end of the waterproof sealing sleeve. The fluororubber material is resistant to aging and has good waterproof performance. The nickel-chromium alloy wire mesh improves the structural strength of the sealing sleeve. The annular sealing lip can enhance the fit with related components and effectively prevent moisture from entering the electrode holder.
[0010] Furthermore, the dustproof net adopts a double-layer composite structure, with a fiber adsorption layer sandwiched between the two layers. The inner wall of the sound outlet has a stepped groove corresponding to the dustproof net, and the edge of the dustproof net is inserted into the stepped groove. The combination of the double-layer composite structure and the fiber adsorption layer can more efficiently block and adsorb dust. The stepped groove makes the dustproof net more stable and less prone to loosening, thus continuously ensuring the cleanliness of the sound outlet.
[0011] Furthermore, the upper diameter of the conical ring is larger than the lower diameter, the inside of the conical ring is lined with absorbent cotton, and the height of the conical ring is twice the thickness of the sealing cap.
[0012] The beneficial effects of this invention are as follows: By adding a dustproof mesh at the sound outlet of the earphone shell and a waterproof membrane inside the earphone shell, the waterproof membrane can protect the gap between the sealing cover and the earphone shell after assembly, preventing moisture from directly affecting the internal components of the earphone shell and improving the waterproof quality of the Bluetooth earphone. At the same time, the added sealing gasket and conical ring allow the conical ring to compress the sealing gasket during assembly with the battery compartment, causing it to deform and expand outward, thereby sealing the gap between the sealing cover and the battery compartment. The compression of the sealing gasket by the conical ring also ensures that the sealing gasket fits tightly against the gap, effectively preventing moisture and dust from entering the battery compartment. Furthermore, this sealing method does not require complicated operating procedures; simply engaging the sealing cover and the battery compartment is sufficient to achieve a seal, without adding extra operational burden during use, thus balancing protective performance and ease of use.

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.
[0019] In this embodiment, refer to Figures 1-4 The Bluetooth headset with a waterproof and dustproof structure implemented therein includes a headset shell 1, a battery compartment 2 installed at the bottom of the headset shell 1, a sealing cover 3 snapped onto the outside of the headset shell 1, a waterproof membrane 6 inserted inside the headset shell 1 and the sealing cover 3, a dustproof mesh 4 installed inside the sound outlet of the headset shell 1 and the sealing cover 3, a sealing cover 5 snapped onto the bottom of the battery compartment 2, a battery 7 inserted inside the battery compartment 2, a contact 8 inserted inside the sealing cover 5, a sealing gasket 9 affixed to the top of the sealing cover 5, a conical ring 11 inserted into the lower side of the inner wall of the sealing cover 5, electrode seats 12 installed on both sides of the bottom of the battery 7, and pins 10 connected to the top sides of the contact 8 at positions corresponding to the electrode seats 12. A main control circuit board is added inside the headset shell 1, the main control circuit board including a Bluetooth chip, a microphone, a speaker, an antenna and related circuit components.
[0020] By adding a dustproof mesh 4 at the sound outlet of the earphone shell 1 and a waterproof membrane 6 inside the earphone shell 1, the waterproof membrane 6 can protect the gap between the sealing cover 3 and the earphone shell 1 after assembly, preventing moisture from directly affecting the internal components of the earphone shell 1 and improving the waterproof quality of the Bluetooth earphone. At the same time, the added sealing gasket 9 and conical ring 11 can seal the gap between the sealing cover 5 and the battery compartment 2 by squeezing the sealing gasket 9 with the conical ring 11 when assembling the sealing cover 5 and the battery compartment 2. The squeezing action of the conical ring 11 on the sealing gasket 9 can make the sealing gasket 9 fit tightly against the gap, effectively preventing moisture and dust from entering the battery compartment 2 through the gap. Moreover, the sealing method of this structure does not rely on complicated operation steps. The sealing effect can be achieved simply by completing the normal engagement of the sealing cover 5 and the battery compartment 2, without adding extra operation burden during use, thus balancing protection performance and ease of use.
[0021] The waterproof membrane 6 is made of polytetrafluoroethylene microporous filter membrane. The surface of the waterproof membrane 6 is coated with a hydrophobic nano coating. The outside of the waterproof membrane 6 is connected to the inner wall of the earphone shell 1 by dispensing adhesive. The top of the electrode base 12 is fitted with a waterproof sealing sleeve. The waterproof sealing sleeve is made of fluororubber material and has a nickel-chromium alloy wire braided mesh embedded inside. The end of the waterproof sealing sleeve is provided with an annular sealing lip.
[0022] The dustproof net 4 adopts a double-layer composite structure. A fiber adsorption layer is sandwiched between the two layers of the dustproof net 4. The inner wall of the sound outlet is provided with a stepped groove corresponding to the dustproof net 4. The edge of the dustproof net 4 is inserted into the stepped groove. The upper diameter of the conical ring 11 is larger than the lower diameter. The inside of the conical ring 11 is lined with absorbent cotton. The height of the conical ring 11 is twice the thickness of the sealing cover 5.
[0023] This solution improves the waterproofing of Bluetooth headsets by adding a dustproof mesh 4 at the sound outlet of the earphone shell 1 and a waterproof membrane 6 inside the earphone shell 1. The waterproof membrane 6 protects the gap between the sealing cover 3 and the earphone shell 1 after assembly, preventing moisture from directly affecting the internal components of the earphone shell 1. Simultaneously, the added sealing gasket 9 and conical ring 11 allow the sealing cover 5 and battery compartment 2 to be assembled. The conical ring 11 compresses the sealing gasket 9, causing it to deform and expand outward, thus sealing the gap between the sealing cover 5 and the battery compartment 2. The compression of the sealing gasket 9 by the conical ring 11 ensures a tight fit, effectively preventing moisture and dust from entering the battery compartment 2. Furthermore, this sealing method does not require complex operating procedures; simply engaging the sealing cover 5 and battery compartment 2 achieves a seal, without adding extra operational burden during use, balancing protective performance and ease of use.

It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the scope of protection of the present invention.
