[0035] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0036] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other. The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout.
[0037] This invention provides a charging device for audio guides, used for charging and sterilizing the audio guide. Specifically, the charging device can charge and sterilize the audio guide simultaneously, or it can charge without sterilizing.
[0038] Please see Figures 1-3 This utility model provides a charging device for a tour guide, including a bottom shell 10, a circuit board 40, a lamp holder 31, an ultraviolet lamp 30, and a charging plate 21.
[0039] The bottom shell 10 has a panel 20, on which several charging plates 21 are provided, each charging plate 21 having a magnetic base 22. A lamp holder 31 is provided on the panel 20, and an ultraviolet lamp 30 is provided on the lamp holder 31. A circuit board 40 is provided inside the bottom shell 10 and is electrically connected to the ultraviolet lamp 30 and the charging plate 21.
[0040] The present invention relates to a charging device for audio guides. By fixing a lamp holder 31 to the panel 20 and installing an ultraviolet lamp 30 on the lamp holder 31, the ultraviolet lamp 30 can disinfect and sterilize the audio guide placed on the charging plate 21, thus enabling the audio guide to be charged and disinfected simultaneously. In this way, the audio guide does not need to be disinfected with alcohol before each use, making the operation simple and convenient.
[0041] In addition, by integrating the UV lamp 30 into the audio guide charging device, it occupies less space. The UV lamp 30 has also been improved to suit the working environment of the audio guide charging device.
[0042] In one specific embodiment, the ultraviolet lamp 30 is detachably mounted on the lamp holder 31.
[0043] When the UV lamp 30 is installed in the lamp holder 31, the UV lamp 30 is electrically connected to the circuit board 40, and can thus be controlled by the circuit board 40. When the UV lamp 30 is removed from the lamp holder 31, the UV lamp 30 is disconnected from the circuit board 40.
[0044] The detachable connection between the lamp holder 31 and the ultraviolet lamp 30 allows users to easily remove the ultraviolet lamp 30 from the lamp holder 31 and replace it when the disinfection effect of the ultraviolet lamp 30 is significantly reduced or damaged. This eliminates the need to send the entire audio guide charging device back to the factory for repair, saving time and effort.
[0045] Optionally, the lamp holder 31 can be a screw-in structure. When the lamp holder 31 is a screw-in structure, the UV lamp 30 can be screwed in and out of the screw-in structure. When the UV lamp 30 is fully screwed into the screw-in structure, the UV lamp 30 is fixedly connected to the screw-in structure, the filament of the UV lamp 30 is in contact with the electrical contacts, and the circuit board 40 is electrically connected to the UV lamp 30. When it is necessary to replace the UV lamp 30, the screw-in structure of the UV lamp 30 is unscrewed out.
[0046] In one specific embodiment, the lamp holder 31 is fixedly mounted on the bottom wall of the panel 20. A through hole is formed in the panel 20, and the ultraviolet lamp 30 is fixed to the lamp holder 31 and extends out through the through hole in the panel 20. In this way, by placing the lamp holder 31 on the inside of the panel 20, the overall size of the audio guide charging device is made more compact.
[0047] The lamp holder 31 and the panel 20 can be detachably connected. For example, the lamp holder 31 can be fixed to the panel 20 by screws passing through the panel 20 and the lamp holder 31. In this way, the panel 20 and the lamp holder 31 are fixed by assembly, and the material selection for the lamp holder 31 and the panel 20 is not limited by mechanical strength. Alternatively, the lamp holder 31 can be welded to the panel 20, resulting in a high mechanical strength connection between the lamp holder 31 and the panel 20. The connection method between the lamp holder 31 and the panel 20 is only exemplarily presented and is not limited thereto.
[0048] In one specific embodiment, the ultraviolet lamp 30 is further covered by a protective cover 32, which is fixedly mounted on the panel 20. The protective cover 32 is used to reduce interference from the external environment on the ultraviolet lamp 30, so that the ultraviolet lamp 30 operates more stably and has a longer service life. For example, if the audio guide charging device is bumped to the ground, the protective cover 32 can prevent the filament of the ultraviolet lamp 30 from directly contacting the ground.
[0049] Furthermore, the ultraviolet lamp 30 is positioned at the geometric center of the panel 20, and several charging plates 21 are arranged around the ultraviolet lamp 30. In this way, the ultraviolet lamp 30 can evenly sterilize the surrounding audio guides. That is, by arranging the charging plates 21 around the ultraviolet lamp 30, the power of the ultraviolet lamp 30 can be utilized to the maximum extent, ensuring that audio guides close to the ultraviolet lamp 30 meet the disinfection standards while those farther away do not.
[0050] Optionally, the shield 32 is provided with openings around its perimeter to allow ultraviolet light to pass through, so as to prevent the ultraviolet light emitted by the ultraviolet lamp 30 from being interfered with by the shield 32.
[0051] Of course, the positions of the UV lamp 30 and the charging plate 21 are not limited to the specific limitations of the above embodiments. Users can adjust the specific positions of the UV lamp 30 and the charging plate 21 according to their actual needs. For example, when the area of the panel 20 is small or the power of the UV lamp 30 is large enough, the UV lamp 30 can also be arranged on one side of several charging plates 21.
[0052] In one specific embodiment, the protective cover 32 is configured to be detachably connected to the panel 20. When the UV lamp 30 needs to be replaced, the protective cover 32 is first removed from the panel 20. After the UV lamp 30 is installed on the lamp holder 31, the protective cover 32 is then installed on the panel 20. In this way, the lifespan of the UV lamp 30 is improved while also reducing the assembly difficulty of the UV lamp 30.
[0053] Specifically, the cover 32 includes two mounting flanges disposed opposite to each other, and fasteners are inserted through the mounting flanges and the panel 20 to detachably mount the cover 32 onto the panel 20.
[0054] Please see Figure 4 In another specific embodiment, the guide's charging device also supports a disinfection mode where disinfection precedes charging.
[0055] In one specific embodiment, the circuit board 40 is provided with a working circuit. The working circuit is connected to the ultraviolet lamp 30, the charging board 21, and the magnetic base 22. The working circuit of the circuit board 40 includes a power input socket 41, a first power adapter board 42, a second power adapter board 43, a first boost module 44, and a second boost module 45.
[0056] The input terminal of the power input socket 41 is connected to a power source, and the output terminal of the power input socket 41 is connected to the input terminal of the first power adapter board 42 and the input terminal of the second power adapter board 43. The input terminal of the first boost module 44 is connected to the output terminal of the first power adapter board 42, and the input terminal of the second boost module 45 is connected to the output terminal of the first power source. The output terminal of the second power adapter board 43 is connected to the input terminals of several charging boards 21.
[0057] The working circuit has contacts a, b, and c. Contact a is connected to the output terminal of the power input socket 41, contact b is connected to the input terminal of the first power adapter board, and contact c is connected to the input terminal of the second power adapter board.
[0058] Switch 46 can be switched between a first position and a second position. When switch 46 is in the first position, switch 46 connects contact a and contact b to connect the power input socket 41 and the first power adapter plate 42. When switch 46 is in the second position, switch 46 connects contact a and contact c to connect the power input socket 41 and the second power adapter plate 43.
[0059] When it is necessary to disinfect the audio guide before charging, first control switch 46 to contact contacts a and c to disinfect the audio guide, and then switch switch 46 to contact contacts a and b to charge the audio guide.
[0060] In one specific embodiment, a power input socket 41 is used to connect to a power source. A first power adapter board 42 is used to receive the voltage transmitted from the power input socket 41 and maintain a constant voltage during transmission. A first boost module 44 is used to boost the voltage to a first preset voltage U1. A second boost module 45 is used by the first boost module 44 to further boost the voltage from the first preset voltage U1 to a second preset voltage U2. The ultraviolet lamp 30 actually operates at the second preset voltage U2. The second preset voltage U2 is higher than the first preset voltage U1.
[0061] The second power adapter board 43 is used to receive the voltage transmitted from the power input socket 41 and maintain a constant voltage during the transmission process. It is also used to supply power to several charging boards 21, which in turn supply power to the magnetic base 22.
[0062] In this embodiment, the operating circuit sequentially boosts the voltage input to the power input socket 41 via the first boost module 44 and the second boost module 45, enabling the UV lamp 30 to operate at the second preset voltage U2. This significantly reduces the current of the UV lamp 30, thereby reducing its heat generation and enhancing safety. Furthermore, when the switch 46 is closed, the audio guide can be charged and sterilized simultaneously.
[0063] Furthermore, several charging boards 21 are connected in parallel. In this way, when one charging board 21 fails, the other charging boards 21 can still work normally.
[0064] It should be noted that, compared to a single boost module, both the first boost module 44 and the second boost module 45 undertake a portion of the boost ratio, avoiding the problem of a single stage approaching the limit duty cycle, and thus achieving a higher overall boost ratio and overall efficiency.
[0065] In one specific embodiment, the voltage output by the power input socket 41 is 5V, the first preset voltage U1 is 12V, and the second preset voltage U2 is 32V.
[0066] In other words, the first boost module 44 increases the voltage from 5V to 12V, and the second boost module 45 further increases the voltage from 12V to 30V. The UV lamp 30 operates at 32V.
[0067] In this embodiment, the working circuit adopts a scheme of first connecting a lower voltage and then gradually increasing the voltage, which avoids connecting the tour guide charging device to 220V AC power, reduces the risk of leakage of the tour guide charging device, and enhances safety.
[0068] Please see Figure 5In an alternative embodiment, the circuit structure is largely the same as the above embodiment, except that a switch 46 is provided between the power input socket 41 and the first power adapter board 42. The switch 46 is used to control the power input socket 41 to connect with the first power adapter board 42 and the second power adapter board 43.
[0069] Specifically, switch 46 can switch between a closed state and an open state. When switch 46 is in the closed state, both the first power adapter plate 42 and the second power adapter plate 43 are connected to the first power adapter plate 42 and the second power source. When switch 46 is in the open state, both the first power adapter plate 42 and the second power adapter plate 43 are disconnected from the first power adapter plate 42 and the second power source.
[0070] Please refer to it again. Figure 1 and Figure 6 In one embodiment, an annular magnetic chuck 22 is provided on the charging plate 21. The annular magnetic chuck 22 adopts an annular magnetic connector, the center 221 of the annular magnetic chuck is the positive pole, and the annular magnet 222 of the annular magnetic chuck 22 is the negative pole.
[0071] The bottom of the audio guide has a magnetic interface, which is the same size as the annular magnetic connector but with opposite magnetic properties. The annular magnetic connector and the annular magnetic head are magnetically connected to secure the audio guide to the annular magnetic base 22. After being fully charged, the audio guide can be pulled out by using external force to overcome the magnet's magnetic force.
[0072] Specifically, the center 221 of the annular magnetic base 22 is a raised metal contact. When the audio guide is attracted into position, it contacts this metal contact to receive positive current. The annular magnet 222 is an annular metal contact 221 surrounding the center of the annular magnetic base 22. The annular contact on the audio guide contacts the annular metal contact of the annular magnet 222, forming a charging circuit.
[0073] The magnetic charging base uses magnetic adsorption technology to achieve automatic alignment with the audio guide. The audio guide only needs to be placed near the magnetic base 22, which greatly improves the user experience.
[0074] In one specific embodiment, the panel 20 is detachably connected to the bottom shell 10. Thus, when the panel 20 is damaged, the user only needs to replace the panel 20, without needing to replace the entire audio guide charging device, resulting in low operating costs.
[0075] In summary, the external 5V DC voltage is input through the power input socket 41, then passes through the switch 46. One path of the voltage is boosted to 12V by the first boost module, and then boosted to 32V by the second boost module. Finally, the UV lamp 30 operates at 32V. The other path passes through the charging board 21 to the magnetic base 22. The voltage is still 5V when it reaches the magnetic base 22. Charging is initiated by the magnetic attraction between the magnetic head and the bottom magnetic head of the receiver. The charging circuit is built into the receiver.
[0076] Currently, switch 46 has two sockets. Connecting one socket activates the charging function, while connecting the other socket activates the disinfection function.
[0077] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom still fall within the protection scope of this invention.
