[0034] Bluetooth headsets are hands-free headsets that use Bluetooth technology, allowing users to avoid the entanglement of wires and easily make calls or listen to music in various ways. With the improvement of people's living standards, the application of Bluetooth headsets has been greatly promoted, especially favored by sports enthusiasts.

[0035] Currently, silicone covers are generally used to provide corresponding waterproof operations for sports earplugs. However, during long-term use, sweat may penetrate into the neck cover connection, and the user cannot promptly know that sweat has penetrated into the device, which may cause damage to the Bluetooth headset and affect the reliability and service life of the device.

[0036] Figure 1 The overall structural diagram of the Bluetooth headset according to the embodiment of the utility model is schematically shown. Figure 2 for Figure 1 A cross-sectional view of the structure of a Bluetooth headset. Figure 1 and 2As shown, the utility model proposes a Bluetooth headset. The Bluetooth headset in the utility model includes a neck sleeve 10, an earphone assembly 20 and a warning assembly. The neck sleeve 10 is bent and forms a storage space for accommodating the neck. Both ends of the neck sleeve 10 are provided with connection ports respectively. The neck sleeve 10 has an opening 11 on the side facing the storage space. The neck sleeve 10 has an inner cavity connected to the opening 11. Two earphone assemblies 20 are provided, each earphone assembly 20 is connected to a connection port. The warning assembly is arranged in the inner cavity of the neck sleeve 10. The warning assembly includes a liquid absorption expansion assembly 31, a linkage 32 and a movable block 33. The liquid absorption expansion assembly 31 is located in the connection port. The linkage 32 is connected to the movable block 33. The movable block 33 is arranged in the opening 11. The liquid absorption expansion assembly 31 can drive the movable block 33 to extend out of the opening 11 through the linkage 32.

[0037] According to the Bluetooth headset of the present invention, the two connection ports of the neck cover 10 are respectively connected to the two earphone components 20, and the liquid absorption expansion component 31 of the warning component is arranged in the connection port. Since the connection port is close to the connection position of the neck cover 10 and the earphone component 20, the liquid absorption expansion component 31 can absorb sweat from the neck and expand. The liquid absorption expansion component 31 in the expanded state can drive the movable block 33 to extend out of the opening 11 through the linkage part 32, and perform operations such as touching the neck located in the accommodating space, so that the user knows that sweat has penetrated into the Bluetooth headset, and then completes subsequent maintenance operations. The utility model can warn the user of sweat penetrating into the Bluetooth headset, and give the user a physical reminder in time, thereby ensuring the reliability of the Bluetooth headset and improving the service life of the Bluetooth headset.

[0038] In some embodiments of the present invention, Figure 3 and 4As shown, the linkage member 32 has a first channel 325, the first channel 325 has a first port 321 and a second port 322, the partially movable block 33 is slidably disposed in the first port 321 and can pass through the opening 11 and move toward the accommodation space, the partially liquid-sucking expansion component 31 is slidably disposed at the second port 322, and the first channel 325 is filled with fluid. In this embodiment, the linkage member 32 is a hydraulic chamber structure, having a first channel 325 for containing liquid, the partially movable block 33 is slidably disposed in the first port 321, and the partially liquid-sucking expansion component 31 is slidably disposed in the second port 322. When sweat penetrates into the connection position between the earphone component 20 and the connection port, the liquid absorption expansion component 31 is located in the connection port and close to the connection position between the earphone component 20 and the connection port, so it can absorb the sweat and then expand itself. The liquid absorption expansion component 31 in the expanded state changes its own volume, and then changes its position in the second port 322, which is equivalent to part of the liquid absorption expansion component 31 sliding in the first channel 325. Since there is liquid in the first channel 325, the movable block 33 of the first port 321 can be driven by the liquid, so that the movable block 33 passes through the opening 11 and reaches the position of the accommodating space, and then touches the user, so that the user knows that sweat has penetrated into the Bluetooth headset, and then completes the subsequent maintenance operations.

[0039] Specifically, in this embodiment, the first channel 325 has a cavity in a vacuum state, and the expansion of the liquid absorption expansion component 31 can also drive the movable block 33 of the first port 321 through the vacuum pressure, so that the movable block 33 passes through the opening 11 and reaches the position of the accommodating space.

[0040] Specifically, in the utility model, the linkage member 32 can also be a combination structure of a fixed seat and a gear structure, the gear structure can be rotatably mounted on the fixed seat along its own axis, the liquid absorption expansion component 31 is meshingly connected with the gear structure, the movable block 33 is meshingly connected with the gear structure, and the meshing section of the liquid absorption expansion component 31 and the gear structure is the first section, and the meshing section of the movable block 33 and the gear structure is the second section. The first section and the second section are set at an angle greater than zero, so that the liquid absorption expansion component 31 in the expanded state can drive the movable block 33 to extend out of the opening 11 through the meshing transmission of the gear structure, and perform operations such as touching the neck located in the accommodating space, so that the user knows that sweat has penetrated into the Bluetooth headset.

[0041] In some embodiments of the present invention, Figure 4As shown, the warning component includes a shielding block 34, which is arranged between the opening 11 and the movable block 33 and can move along the extension direction of the neck cover 10. The linkage member 32 has a second channel, one end of the second channel is connected to the first channel 325, and the other end of the second channel has a third port 323, the third port 323 is connected to the shielding block 34, and the second channel is filled with fluid. In this embodiment, a partial shielding block 34 is slidably arranged in the third port 323 of the second channel, and the shielding block 34 is arranged between the opening 11 and the movable block 33, which is used to prevent external sweat from entering the inner cavity of the neck cover 10 through the opening 11, and plays a protective role.

[0042] Specifically, when sweat penetrates the connection position between the earphone component 20 and the connection port, the liquid absorption expansion component 31 can absorb the sweat and then expand itself. The liquid absorption expansion component 31 in the expanded state changes its volume, so that the position in the second port 322 changes. Since there is liquid in both the first channel 325 and the second channel, the shielding block 34 of the third port 323 and the movable block 33 of the first port 321 can be driven at the same time. The movable block 33 is located on the side of the shielding block 34 away from the opening 11. The shielding block 34 moving along the axial direction of the neck cover 10 will reach the position of the shielding block 34 after it moves to be offset from the opening 11, and then passes through the opening 11 and reaches the accommodation space to touch the user, so that the user knows that the sweat has penetrated into the Bluetooth headset, and then completes the subsequent maintenance operation.

[0043] Specifically, in this embodiment, during the movement of the movable block 33 and the shielding block 34 respectively, the distance between the shielding block 34 and the movable block 33 needs to be specifically calculated according to specific circumstances, so as to ensure that the movable block 33 reaches the position of the shielding block 34 and finally moves out of the opening 11 only after the shielding block 34 moves to be misaligned with the opening 11.

[0044] In some embodiments of the present invention, Figure 4 As shown, a blocking plate 3241 and an elastic component are provided in the first channel 325, and both the blocking plate 3241 and the elastic component are close to the connection between the first channel 325 and the second channel, and the elastic component is respectively connected to the inner wall surface of the first channel 325 and the blocking plate 3241, and one end of the blocking plate 3241 is connected to the inner wall surface of the first channel 325, and the other end of the blocking plate 3241 can rotate around one end of the blocking plate 3241. In this embodiment, the blocking plate 3241 and the elastic component are respectively opened into the first port 321, and the blocking plate 3241 can block the liquid from the first channel 325 to the first port 321 with a certain force. When the expansion of the liquid absorption expansion component 31 is large enough, the blocking plate 3241 will be rotated by the liquid, thereby realizing the connection operation between the first channel 325 and the second channel.

[0045] Specifically, in this embodiment, when sweat penetrates the connection position between the earphone component 20 and the connection port, the liquid absorption expansion component 31 can absorb the sweat and then expand itself. The liquid absorption expansion component 31 in the expanded state changes its volume, so that the position in the second port 322 changes. Since there is liquid in both the first channel 325 and the second channel, and the first channel 325 is provided with a blocking plate 3241 and an elastic component near the first port 321, the blocking plate 3241 and the elastic component will block the liquid leading to the first port 321, so that the liquid in the first channel 325 preferentially flows to the second channel, and preferentially moves the blocking block 34 of the third port 323. When the expansion of the liquid absorption expansion component 31 is large enough, the blocking plate 3241 will be driven by the liquid, and the blocking plate 3241 will be caused to rotate, thereby realizing the connection between the first channel 325 and the second channel. At this time, the liquid will drive the movable block 33 of the first port 321 to move along the accommodation space. The setting of the blocking plate 3241 and the elastic component can ensure that the liquid in the first channel 325 and the second channel preferentially drives the shielding block 34, which can further prevent the movable block 33 from interfering with the shielding block 34 when moving, thereby improving reliability.

[0046] In some embodiments of the utility model, the blocking plate 3241 has a blocking state and a flow state. When in the blocking state, the blocking plate 3241 is perpendicular to the flow direction of the fluid flowing through the blocking plate 3241, so that the first channel 325 and the second channel are separated. When in the flow state, the blocking plate 3241 and the flow direction of the fluid flowing through the blocking plate 3241 are set at an angle greater than zero, so that the first channel 325 and the second channel are connected. In this embodiment, in the blocking state, the liquid absorption expansion component 31 will change the position of part of the liquid absorption expansion component 31 in the second port 322 due to the increase in volume, thereby driving the liquid. The initial driving force is less than the elastic holding force of the elastic component on the blocking plate 3241. At this time, the cross section of the blocking plate 3241 is perpendicular to the flow direction of the fluid passing through the blocking plate 3241, and the liquid will preferentially drive the blocking block 34. As the liquid absorption expansion component 31 continues to expand, the driving force on the liquid at the second port 322 will increase. When the driving force is greater than the elastic retaining force of the elastic component on the blocking plate 3241, the cross-section of the blocking plate 3241 is set at an angle greater than zero to the flow direction of the fluid passing through the blocking plate 3241 (that is, the blocking plate 3241 rotates), and the liquid will pass through the blocking plate 3241 and reach the first port 321, thereby driving the movable block 33.

[0047] In some embodiments of the present invention, Figure 4As shown, the elastic component includes a first elastic member 3242 and a second elastic member 3243, one end of the first elastic member 3242 and one end of the second elastic member 3243 are respectively connected to opposite sides of the blocking plate 3241, and the other end of the first elastic member 3242 and the other end of the second elastic member are respectively connected to the inner wall surface of the first channel 325. In this embodiment, the first elastic member 3242 and the second elastic member 3243 are respectively connected to opposite sides of the blocking plate 3241, and can elastically support the blocking plate 3241 from the opposite sides of the blocking plate 3241, so as to ensure that the blocking plate 3241 maintains a blocking state when the liquid absorption and expansion component 31 does not absorb sweat and expand.

[0048] In some embodiments of the present invention, Figure 5 As shown, the liquid-absorbing expansion component 31 includes a water-absorbing expansion member, a connecting member 312 and a sliding member 313, a part of the sliding member 313 is slidably connected to the second port 322, one end of the connecting member 312 is connected to the sliding member 313, and the other end of the connecting member 312 is connected to the water-absorbing expansion member, and the water-absorbing expansion member is arranged in the connecting port. In this embodiment, the water-absorbing expansion member is a water-absorbing sponge, which can expand itself when absorbing sweat, that is, increase its volume. Since the connecting member 312 is respectively connected to the water-absorbing sponge and the sliding member 313, when the water-absorbing sponge expands, it can drive the sliding member 313 to move in a direction away from the water-absorbing sponge, and then drive the shielding block 34 and the movable block 33 respectively through the liquid in the first channel 325 and the second channel.

[0049] Specifically, in this embodiment, one end of the sliding member 313 facing the linkage member 32 can abut against the second port and can move toward the hydraulic chamber, and one end of the sliding member 313 facing the linkage member 32 can also be arranged in the second port and can move toward the hydraulic chamber. In both cases, the movable block 33 and the blocking block 34 can be driven respectively by the fluid in the hydraulic chamber.

[0050] In some embodiments of the present invention, Figure 5 As shown, the Bluetooth headset further includes a protective component, which is disposed in the inner cavity of the neck cover 10, and is connected to the sliding member 313, and can move toward the headset assembly 20 with the movement of the sliding member 313, so as to partially block the connection position between the connection port and the headset assembly 20. In this embodiment, when sweat penetrates into the connection between the headset assembly 20 and the neck cover 10, the protective component can partially block the connection position between the connection port and the headset assembly 20, thereby reducing the risk of sweat penetrating and flowing to the headset assembly 20.

[0051] In some embodiments of the present invention, Figure 5As shown, the protective component includes a gear 352, a rack 351 and a sealing member 353. The gear 352 is meshed with the rack 351 and the sliding member 313 respectively. The rack 351 is slidably disposed on the inner wall surface of the neck sleeve 10. The sealing member 353 is disposed on the side of the liquid absorption expansion member 311 facing the earphone assembly 20. The sealing member 353 can move toward the earphone assembly 20 with the movement of the sliding member 313 to partially block the connection position between the connection port and the earphone assembly 20. In this embodiment, after the water-absorbing sponge absorbs sweat, it expands itself. The liquid-absorbing expansion component 31 in the expanded state changes its own volume and drives the sliding component 313 to move in the direction away from the water-absorbing sponge through the connecting component 312. At the same time, since the rack 351 is meshed with the sliding component 313 through the gear 352, the rack 351 can drive the blocking component 353 to move toward the earphone assembly 20. Since the blocking component 353 is in the connection position between the earphone assembly 20 and the neck cover 10, it can block the gap at the connection position between the earphone assembly 20 and the neck cover 10, thereby reducing the risk of sweat penetrating and flowing to the earphone assembly 20.

[0052] Specifically, in this embodiment, the blocking member 353 has a hollow structure for the connection line between the earphone assembly 20 and the neck cover 10 to pass through.

[0053] Specifically, in the present embodiment, the neck cover 10 is a split structure, which facilitates the assembly of the warning component into the inner cavity of the neck cover 10 . The split structure can be subsequently connected together by heating or using a connecting agent.

[0054] In some embodiments of the present invention, Figure 1 and 2 As shown, there are two warning components, both of which are arranged in the inner cavity of the neck cover 10, and the liquid absorption expansion component 31 corresponding to each warning component is located in a connection port. There are two openings 11, and the movable block 33 corresponding to each warning component is arranged corresponding to one opening 11. In this embodiment, two warning components, two openings 11 and two connection ports are included, and the three are matched one by one, that is, one warning component matches one connection port and one opening 11. The structure of two warning components can absorb and warn the sweat at the positions of the two connection ports respectively, further improving the reliability of the Bluetooth headset.

[0055] Specifically, in this embodiment, the earphone assembly 20 includes an earphone body 21 and an earplug 22 . The earphone body 21 is connected to the connection port, and the earplug 22 is connected to a side of the earphone body 21 facing away from the neckband 10 .

[0056] Furthermore, the working principle of the utility model is as follows: when sweat penetrates the connection position between the earphone assembly 20 and the connection port, the water-absorbing sponge can absorb the sweat, and expand itself when absorbing the sweat, that is, increase its volume. Since the connecting member 312 connects the water-absorbing sponge and the sliding member 313 respectively, when the water-absorbing sponge expands, it can drive the sliding member 313 to move in a direction away from the water-absorbing sponge. Since there is liquid in both the first channel 325 and the second channel, and the first channel 325 is provided with a blocking plate 3241 and an elastic component near the first port 321, the blocking plate 3241 and the elastic component will block the liquid leading to the first port 321, so that the liquid in the first channel 325 preferentially flows to the second channel, and preferentially causes the blocking block 34 of the third port 323 to move. When the expansion of the liquid absorption expansion component 31 is large enough, the blocking plate 3241 will be driven by the liquid and caused to rotate, thereby achieving the connection between the first channel 325 and the second channel. At this time, the liquid will drive the movable block 33 of the first port 321 to move along the accommodating space.

[0057] Specifically, when the sliding member 313 moves in a direction away from the absorbent sponge, since the rack 351 is meshed with the sliding member 313 through the gear 352, the rack 351 can simultaneously drive the blocking member 353 to move toward the earphone assembly 20 and reach the gap at the connection position between the earphone assembly 20 and the neck cover 10, and can block the sweat, reducing the risk of sweat penetrating and flowing to the earphone assembly 20.

[0058] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
