Description

Technical Field

[0001] This utility model relates to the field of headphone charging case technology, and in particular to a Bluetooth headphone charging case with a cleaning structure. Background Technology

[0002] The Bluetooth earphone charging case is a portable device that combines the functions of storing and charging Bluetooth earphones. It houses a polymer pouch battery, which is connected to a power source via a charging port, and a power management chip manages the charging process. When the Bluetooth earphones are placed in the charging case, the contacts on the earphones precisely align with the corresponding contacts inside the case, forming a circuit and thus providing power to the earphones.

[0003] However, in actual use, as the usage time increases, the contacts inside the charging case are prone to oxidation from the air and the accumulation of dust and other impurities during daily use, which reduces their contact performance with the earphone contacts, making it difficult to form a stable path and causing poor contact between the two. This ultimately affects the normal charging of the earphones by the charging case, and may even result in charging interruption or failure to charge.

[0004] Therefore, a Bluetooth earphone charging case with a cleaning structure is proposed. Utility Model Content

[0005] The purpose of this invention is to solve the problem that the contacts inside the charging case are easily oxidized by air and accumulate dust and other impurities during daily use, which leads to a decrease in the contact performance between the contacts and the earphone contacts, making it difficult to form a stable path, resulting in poor contact between the two, and ultimately affecting the normal charging of the earphones by the charging case, or even causing charging interruption or failure to charge. Therefore, this invention proposes a Bluetooth earphone charging case with a cleaning structure.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a Bluetooth earphone charging case with a cleaning structure, comprising a charging case body, a case cover hinged to the side wall of the charging case body, an earphone slot formed on the surface of the charging case body, a contact fixedly mounted on the inner wall of the earphone slot, an arc-shaped groove formed on the charging case body relative to the position of the contact, a rotating shaft rotatably connected inside the charging case body, a rigid plate fixedly mounted on the circumferential surface of the rotating shaft, the rigid plate being located within the arc-shaped groove, and a plurality of brush bristles fixedly mounted on the surface of the rigid plate, the brush bristles abutting against the inner wall of the arc-shaped groove.

[0007] The effect achieved by the above components is as follows: by setting components such as the rotating shaft and brush bristles, when the contacts of the charging case body are not making good contact, the brush bristles can be used to brush the surface of the contacts to clean the oxide layer and impurities on the surface of the contacts, ensuring that the charging case body can charge the earphones normally.

[0008] Preferably, a slide rod is slidably connected to the inner wall of the rotating shaft, and a connecting rod is fixedly mounted on the upper end of the slide rod, the connecting rod being slidably connected to the charging case body.

[0009] The effect achieved by the above components is that by setting the slide bar, the connecting rod can extend out of the charging compartment body, and rotating the connecting rod can drive the slide bar to rotate, thereby driving the rotating shaft to rotate.

[0010] Preferably, the cross-section of the slide bar has a polygonal structure.

[0011] The effect achieved by the above components is that the slider with a polygonal cross-section can stably drive the rotating shaft to rotate.

[0012] Preferably, a limiting hole is formed on the surface of the rotating shaft, and a limiting block is fixedly mounted on the surface of the slide rod, with the limiting hole and the limiting block being slidably connected.

[0013] The effect achieved by the above components is that the limiting hole and the limiting block can prevent the slide rod from coming out of the rotating shaft.

[0014] Preferably, an extension plate is fixedly mounted on the circumferential surface of the connecting rod, and a slot adapted to the diffraction plate is opened on the surface of the charging compartment body.

[0015] The effect achieved by the above components is that the extension plate can easily rotate the connecting rod, and the slot can accommodate the extension plate, making it convenient to store the extension plate.

[0016] Preferably, the surface of the extension plate is provided with a plurality of anti-slip grooves.

[0017] The effect achieved by the above components is that the anti-slip grooves can increase the friction on the surface of the extension plate, making it easier to rotate the extension plate.

[0018] Preferably, a protrusion is fixedly mounted on the upper end of the connecting rod. The protrusion has a frustum structure, and a groove adapted to the protrusion is opened on the surface of the compartment cover.

[0019] The aforementioned components achieve the following effects: the protrusions of the frustum structure allow the connecting rod to be easily pulled out of the charging compartment body, while the grooves prevent the protrusions from interfering with the normal closing of the compartment cover.

[0020] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, by setting components such as a rotating shaft and brush bristles, when the contacts of the charging case body are not making good contact, the brush bristles can be used to brush the surface of the contacts to clean the oxide layer and impurities on the surface of the contacts, ensuring that the charging case body can charge the earphones normally.

[0021] 2. In this utility model, the protrusion of the frustum structure can easily pull the connecting rod out of the charging compartment body, and the groove can prevent the protrusion from interfering with the normal closing of the compartment cover. Attached Figure Description

[0024] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0026] like Figures 1-4 As shown, this utility model provides a Bluetooth earphone charging case with a cleaning structure, including a charging case body 1. The charging case body 1 has a built-in polymer soft-pack battery and a power management chip. A case cover 2 is hinged to the side wall of the charging case body 1. An earphone slot 3 is formed on the surface of the charging case body 1. A contact 4 is fixedly installed on the inner wall of the earphone slot 3. An arc-shaped groove 5 is formed on the charging case body 1 relative to the contact 4. A rotating shaft 6 is rotatably connected inside the charging case body 1. A rigid plate 7 is fixedly installed on the circumferential surface of the rotating shaft 6. The rigid plate 7 is located in the arc-shaped groove 5. A plurality of brush bristles 8 are fixedly installed on the surface of the rigid plate 7. The brush bristles 8 abut against the inner wall of the arc-shaped groove 5. The power management chip and the contact 4 are electrically connected to the polymer soft-pack battery. By setting the rotating shaft 6 and brush bristles 8, when the contact 4 of the charging case body 1 has poor contact, the surface of the contact 4 can be brushed by the brush bristles 8 to clean the oxide layer and impurities on the surface of the contact 4, ensuring that the charging case body 1 can charge the earphone normally.

[0027] A slide rod 9 is slidably connected to the inner wall of the rotating shaft 6. A connecting rod 10 is fixedly mounted on the upper end of the slide rod 9. The connecting rod 10 is slidably connected to the charging case body 1. By setting the slide rod 9, the connecting rod 10 can extend out of the charging case body 1. When the connecting rod 10 is rotated, it can drive the slide rod 9 to rotate, thereby driving the rotating shaft 6 to rotate.

[0028] The slide bar 9 has a polygonal cross-section, which allows it to stably drive the rotating shaft 6 to rotate.

[0029] A limiting hole 13 is provided on the surface of the rotating shaft 6, and a limiting block 14 is fixedly mounted on the surface of the slide rod 9. The limiting hole 13 and the limiting block 14 are slidably connected. The cooperation between the limiting hole 13 and the limiting block 14 can prevent the slide rod 9 from coming out of the rotating shaft 6.

[0030] An extension plate 11 is fixedly mounted on the circumferential surface of the connecting rod 10. A slot 12 adapted to the diffraction plate is opened on the surface of the charging compartment body 1. The extension plate 11 can easily rotate the connecting rod 10, and the slot 12 can accommodate the extension plate 11, making it convenient to store the extension plate 11.

[0031] The surface of the extension plate 11 is provided with several anti-slip grooves 15. The anti-slip grooves 15 can increase the friction of the surface of the extension plate 11, making it easier to rotate the extension plate 11.

[0032] The upper end of the connecting rod 10 is fixedly fitted with a protrusion 16. The protrusion 16 has a frustum structure. The surface of the cover 2 is provided with a groove 17 that matches the protrusion 16. The frustum structure of the protrusion 16 can easily pull the connecting rod 10 out of the charging compartment body 1. The groove 17 can prevent the protrusion 16 from interfering with the normal closing of the cover 2.

[0033] The overall working principle is as follows: when the internal contact 4 of the Bluetooth headset charging case experiences poor contact due to oxidation, dust, or other impurities, the connecting rod 10 is pulled upward from the charging case body 1 using the protrusion 16 of the frustum structure. The connecting rod 10 drives the sliding rod 9 to rise synchronously until the extension plate 11 is exposed on the surface of the charging case body 1. The extension plate 11, with its anti-slip groove 15, is then rotated. The anti-slip groove 15 increases the friction between the hand and the extension plate 11, causing the extension plate 11 to rotate. Because the sliding rod 9 has a polygonal cross-section and slides through the limiting block 14 and the limiting hole 13 of the rotating shaft 6, the sliding rod 9 can stably drive the rotating shaft 6 to rotate synchronously. Simultaneously, the limiting block 14 prevents… The slide bar 9 disengages from the rotating shaft 6. When the rotating shaft 6 rotates, the rigid plate 7 fixed on its circumferential surface rotates with the rotating shaft 6 in the arc groove 5. The brush bristles 8 on the surface of the rigid plate 7 rotate synchronously and fully contact the contact points 4 on the inner wall of the arc groove 5. The oxide layer and impurities on the surface of the contact points 4 are removed by the brushing action. During the cleaning process, the charging case body 1 can be inverted to facilitate the removal of impurities from the earphone slot 3. After cleaning, the slide bar 9 is pushed back into the rotating shaft 6, and the connecting rod 10 is reset. The extension plate 11 is embedded in the slot 12 of the charging case body 1 to complete the storage. When the case cover 2 is closed, the protrusion 16 at the upper end of the connecting rod 10 is inserted into the groove 17 of the case cover 2 to prevent the protrusion 16 from interfering with the normal closing of the case cover 2.

[0034] At this time, the internal contacts 4 of the charging case 1 are clean. After the Bluetooth earphones are placed into the earphone slot 3, the earphone contacts and the contacts 4 of the charging case 1 can accurately connect to form a stable circuit. The charging case 1 provides normal charging power to the earphones through the internal polymer soft-pack battery and power management chip.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
