[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Reference Figures 1-3This utility model provides an embodiment of a modular multi-form base-style electric fan, comprising: a bottom support base 1 for support and placement; a connecting block 7 rotatably connected to the front end of the bottom support base 1; a flip adjustment plate 2 fixedly connected to the top end of the connecting block 7; a fan 9 fixedly connected inside the flip adjustment plate 2; fixed seats 11 fixedly connected to both sides of the bottom end of the flip adjustment plate 2; a flip rod 12 rotatably connected inside the fixed seats 11; limiting grooves 18 are formed inside the slots on both sides of the top end of the bottom support base 1; the bottom end of the flip rod 12 is slidably connected inside the limiting grooves 18; and limiting components are provided inside both sides of the bottom support base 1 to adjust the angle of the fan blowing air. The limiting components include a lower pressure plate 17 that slides inside the slots on both sides of the bottom support 1. Multiple blocking arc blocks 16 are fixedly connected to the top of the lower pressure plate 17. The bottom of the lower pressure plate 17 is connected to the slots on both sides of the bottom support 1 through multiple compression springs 15. A 14 is fixedly connected to the outside of the lower pressure plate 17. A pressing column 13 is fixedly connected to the top of the 14. The outside of the pressing column 13 is slidably connected to the top two sides of the bottom support 1. A battery 5 is fixedly connected to the front side of the flip adjustment plate 2. The battery 5 is electrically connected to the fan 9. The two sides of the connecting block 7 are connected to the front inside of the bottom support 1 through torsion springs 10. A handle 8 is fixedly connected to the front end of the bottom support 1.
[0027] This fan device features both handheld and desktop usage modes, significantly enhancing its flexibility. In handheld mode, users can start the fan 9 by holding the handle 8 to deliver airflow for cooling. When desktop use is required, the bottom support base 1 is placed on a flat surface, and the adjustment plate 2 is flipped upwards to automatically unfold the support structure. During the flipping process, the fixed base 11 drives the flipping rod 12 to slide along the limiting slide groove 18. When the flipping rod 12 contacts the arc surface of the blocking arc block 16, it pushes the lower pressure plate 17 downwards. After flipping to the set angle, the compression spring 15 returns to its original position, providing stable support for the flipping rod 12 with the flat surface of the blocking arc block 16. To retract the fan, simply press down on the pressing column 13 to disengage the blocking arc block 16, and the flipping adjustment plate 2 automatically returns to its original position under the action of the torsion spring 10. This innovative mechanical linkage structure enables rapid switching between usage modes, allowing the device to adapt to more usage scenarios.
[0028] Reference Figure 1 , Figure 4 and Figure 5The mounting sleeve 3 is used to fix the top of the flip adjustment plate 2. The inner side of the mounting sleeve 3 is nested with a protective filter 4. The bottom end of the protective filter 4 is fixedly connected with multiple connecting posts 23. Multiple connecting components are installed on the inner side of the mounting sleeve 3 to facilitate the disassembly of the protective filter 4. The connecting components include a connecting plate 20 located inside the mounting sleeve 3. A support arc block 19 is fixedly connected to the inner side of the connecting plate 20. The support arc block 19 has an installation slot 21 inside. The outer sides of the connecting posts 23 are slidably connected to the inside of the installation slot 21. Multiple fixing slots 22 are opened around the outer side of the protective filter 4. The front end of the mounting sleeve 3 is threadedly connected with a positioning stud 6. The outer side of the positioning stud 6 is threadedly connected to the inside of the fixing slot 22.
[0029] The protective filter 4 adopts a quick-release design, which is convenient for users to clean and maintain regularly. When dust accumulates on the inside and outside of the filter and needs to be cleaned, simply unscrew the positioning stud 6 and then rotate the protective filter 4 counterclockwise. At this time, the connecting post 23 will slide along the track of the mounting slot 21. When the connecting post 23 moves to the wide slot of the mounting slot 21, the protective filter 4 can be easily removed outward. This innovative snap-on rotating fixing structure not only ensures the stability of the filter during operation, but also enables quick disassembly that can be completed by hand, greatly improving the convenience of daily maintenance and making equipment maintenance more efficient and convenient.
[0030] Working principle: When the fan is in handheld use, the handle 8 is held to the bottom support 1, thereby starting the fan 9 to discharge heat outwards for cooling. When the device is in a stable environment, the bottom support 1 is placed on a flat surface. At this time, the tilting adjustment plate 2 is tilted upwards. As the tilting adjustment plate 2 tilts, the fixed seat 11 generates an upward pulling force on the tilting rod 12, thereby tilting the tilting rod 12. The bottom end of the tilting rod 12 slides inside the limiting slide groove 18, thereby causing the tilting rod 12 to block the arc surface of the basic blocking arc block 16, thus pressing down the lower pressure plate 17. When the tilting adjustment plate 2 tilts to a certain angle, the compression spring 15 presses down on the lower... The pressure plate 17 pushes upward, thereby supporting the flipping rod 12 through the plane of the blocking arc block 16, thus completing the unfolding support of the flipping adjustment plate 2. When retracting, the pressing column 13 is pressed down, the blocking arc block 16 moves down, and the flipping adjustment plate 2 is combined by the torque of the torsion spring 10. After long-term use, dust accumulates on the inner and outer sides of the protective filter screen 4. At this time, the positioning stud 6 is rotated to disassemble it. Then, the protective filter screen 4 is rotated counterclockwise, and the connecting column 23 slides inside the mounting slot 21. When the connecting column 23 moves into the wide slot of the mounting slot 21, the protective filter screen 4 is lifted outward again to complete the disassembly of the protective filter screen 4 for cleaning.
[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
