Example

[0048] See Figures 1-11 As shown, a voice-controlled floor fan includes a base 1, a column 2 mounted on the base 1, a pivot seat mounted on the column 2, and a fan head 3 mounted on the pivot seat. The base 1 is made of non-conductive insulating materials such as plastic, effectively avoiding the risk of electric leakage and ensuring user safety. The base 1 has a charging port 4 with one end exposed. This charging port 4 uses a universal Type-C interface, greatly improving the convenience of power supply. The charging port 4 connects to the mains power supply via a charging cable, providing power for the floor fan's operation. Of course, in addition to Type-C, the charging port 4 can also use other common universal interfaces, such as Micro-USB, as long as it enables convenient power supply.

[0049] The aforementioned fan head 3 includes a DC motor, fan blades connected to the output shaft of the DC motor, and a fan blade safety cover. A stepper motor is mounted on the pivot base to enable the fan head 3 to swing left and right (of course, other motors capable of angle adjustment, such as servo motors, can also be used). A control motherboard is installed inside the fan head 3 to precisely control the operation of the stepper motor and the DC motor, ensuring stable and efficient fan operation. The above is a known existing floor fan structure. This application makes the following improvements based on the above:

[0050] A first conductive plate 21 is provided at the lower end of the column 2, and a locking part 7 is provided inside the base 1 for fixing the lower end of the column 2. At least two independent second conductive plates 5 are provided on the locking part 7. Each second conductive plate is electrically connected to an independent chassis conductive plate 6. One chassis conductive plate is electrically connected to the charging interface 4, and the other chassis conductive plate is electrically connected to a voice control board 8 with an integrated microphone. The voice control board 8 is electrically connected to the control main board, thereby realizing voice remote control of the floor fan. The voice control board 8 is electrically connected to the speaker 9 to enable the floor fan to broadcast announcements.

[0051] When the column 2 is installed on the locking part 7, the first conductive plate 21 and the second conductive plate 5 are connected. Using the first conductive plate 21 of the column 2 as an adapter, the second conductive plate 5 and the chassis conductive plate 6 are connected and wired simultaneously while the column 2 is installed, thereby providing power to the voice control board 8. In this embodiment, there are four chassis conductive plates 6, which, in addition to powering the voice control board 8, can also power other components within the base, improving the wiring within the base 1.

[0052] In this embodiment, the linkage connection between the first conductive sheet 21, the second conductive sheet 5, and the chassis conductive sheet 6 is adopted, which simplifies the wiring connection of the floor fan in the base 1, simplifies the assembly and maintenance process, avoids the complicated wiring process, and improves the practicality of the product.

[0053] In this embodiment, the base 1 consists of a base 11 and a panel 12, which are fastened together by bolts. The panel 12 has a sound-transmitting hole 121 corresponding to the microphone position, ensuring efficient sound transmission and accurate reception of voice commands. The base 11 has a sound-exiting hole 111 corresponding to the speaker 9 position, ensuring clear sound transmission. In this embodiment, the sound-transmitting hole 121 and the sound-exiting hole 111 have a mesh structure; their shape and size are adjustable, and they can function even with slight positional deviations.

[0054] Furthermore, the panel 12 has a first opening 122, the size of which is adapted to the column 2, allowing the column 2 to be stably inserted and achieving a secure connection. The base 11 has an upwardly raised boss 112. The locking part 7 is installed in the middle area of ​​the boss 112 to ensure its fixed position. The chassis conductive plate 6 is located on the upper end face of the boss 112 surrounding the locking part 7, and is used for electrical connection with the second conductive plate 5 on the locking part 7.

[0055] Specifically, the boss 112 has a vertical through hole 113 in the middle, which provides installation space for the locking part 7. The locking part 7 is located in the through hole 113. To ensure stable placement, one end of the locking part 113 or the second conductive piece 5 located on it overlaps the boss 112 at the edge of the through hole 113, thereby preventing it from falling down. Below the boss 112, a locking nut 10 is provided to fix the lower end of the locking part 7, ensuring the stability of the entire structure.

[0056] In this embodiment, the locking part 7 is made of insulating material and has a columnar structure. Its lower end has an external thread 71 that matches the locking nut 10, allowing the locking nut 10 to tightly secure the locking part 7 via a threaded connection. Its upper end has two conductive plate mounting platforms 72 and 73 in a separated state. This design ensures the independence of different circuits and avoids circuit interference in the non-conductive state. Four second conductive plates 5 are independently mounted in pairs on the conductive plate mounting platforms 72 and 73, with one side of each second conductive plate 5 exposed on the outside of the conductive plate mounting platforms 72 and 73 for effective connection with the corresponding chassis conductive plate 6.

[0057] In equivalent implementations, the columnar structure of the locking part 7 can be of various shapes such as cylinder or prism, as long as it can fit the through hole 113 and meet the insulation and installation requirements. The pitch, thread profile, and other parameters of the external thread 71 can also be adjusted according to actual needs, as long as it can achieve a reliable connection with the locking nut 10. The number and shape of the conductive plate mounting platforms 72 and 73 can also be appropriately changed, for example, increasing the number of mounting platforms to meet more circuit connection needs, as long as the independent installation and normal conductive function of the second conductive plate 5 can be guaranteed.

[0058] In this embodiment, there are two types of second conductive plates 5: one is fixed to the conductive plate mounting platform by plugging in, and the other is fixed to the conductive plate mounting platform by screws. Specifically, when fixed to the conductive plate mounting platform by plugging in, the second conductive plate 5 is designed with a plug interface adapted to the mounting platform, which can be quickly and accurately inserted to achieve a stable connection and conductivity; while when fixed with screws, corresponding screw holes are provided on the conductive plate and the mounting platform, and screws are tightened to ensure a firm connection and stable conductivity. At the same time, the column 2 can also be installed and fixed using the above-mentioned screws, making reasonable use of space.

[0059] In this embodiment, there are four second conductive sheets 5, four first conductive sheets 21, and four chassis conductive sheets 6, and two conductive sheet mounting platforms arranged in an arc shape. This arrangement allows for a reasonable layout within a limited space, facilitating circuit connection and functional implementation. Each conductive sheet mounting platform is equipped with two types of second conductive sheets, which can meet different connection requirements within a limited space, improving the flexibility and reliability of the connection.

[0060] In equivalent implementations, the second conductive sheet 5 can also be fixed by snap-fit ​​connection or the like; the number of the second conductive sheets 5 and the shape of the conductive sheet mounting platform can be adjusted according to the actual circuit design and spatial layout, as long as effective conductivity and connection functions can be achieved.

[0061] The second conductive sheet 5 is equipped with a spring sheet 51, which has good elastic deformation capability. When one end of the chassis conductive sheet 6 abuts against the spring sheet 51, it can ensure that the two are tightly attached and achieve stable conductivity. One end of the chassis conductive sheet 6 is bent to form an overlap 61. This structural design can increase the contact area with the spring sheet 51 and further improve conductivity and stability.

[0062] A dedicated mounting platform is provided on the boss for installing the conductive plate 6 of the chassis. The plate is secured to the platform with screws, ensuring a stable installation and preventing displacement or loosening during use, which would affect conductivity. This mounting platform can be integrally formed with the boss 112, simplifying the manufacturing process and enhancing the overall structural stability.

[0063] In equivalent implementations, the shape and material of the spring 51 can be adjusted according to actual conductivity requirements and costs; the overlapping part 61 of the chassis conductive sheet 6 can also adopt other shapes, as long as good contact conductivity can be achieved; in addition to integral molding, the connection between the shelf and the boss can also be a detachable splicing method, which is convenient for later maintenance and replacement.

[0064] Based on the implementation of voice remote control function for the floor fan, the first conductive piece 21 of the column 2 plays a crucial connecting role. When the column 2 is installed on the locking part of the base 1, the first conductive piece 21 and the second conductive piece 5 are in close contact, achieving electrical conductivity between them. The second conductive piece 5 is then connected to the conductive piece 6 of the chassis via a spring piece 51, thus constructing a complete conductive path. This ingenious design not only ensures the stable installation of the column 2 but also achieves electrical wiring between the second conductive piece 5 and the conductive piece 6 of the chassis.

[0065] This wiring structure allows for a stable power supply to the voice control board 8 and other components, providing them with the necessary power for normal operation. Simultaneously, it effectively improves the previously chaotic wiring within the base 1, resulting in a more organized and orderly wiring layout, reducing the risk of wiring failures, and enhancing the overall stability and reliability of the fan.
