Description

Technical Field

[0001] This utility model relates to the field of electric fan technology, and in particular to an electric fan with a tool-free protective frame that can be installed and removed. Background Technology

[0002] In modern life, electric fans are a common household appliance, widely used in homes, offices, shops, and other settings. By generating airflow, they circulate air, lower local temperatures, and bring comfort to people in hot weather, playing an important role in daily life for heatstroke prevention, cooling, and air circulation.

[0003] Currently, electric fans on the market have some issues regarding the removal and installation of protective frames and the adjustment of airflow angle. For the protective frame, most electric fans use screws and nuts for fixing. This method requires users to use screwdrivers or other tools when the protective frame needs to be disassembled for cleaning or maintenance. The process is cumbersome, extremely inconvenient for users without tools or unfamiliar with the operation, consuming a lot of time and increasing maintenance difficulty. Regarding airflow angle adjustment, some electric fans have complex adjustment methods, requiring manual adjustment of multiple components. Some even only allow for limited fixed angle adjustments, failing to meet the diverse needs of users in different scenarios for airflow direction, significantly reducing the user experience. Therefore, how to achieve tool-free removal and installation of electric fan protective frames and convenient and quick adjustment of airflow angle has become an urgent technical problem to be solved. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a tool-free electric fan with a protective frame that can only be disassembled using tools.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] An electric fan with a tool-free protective frame includes a base. Connecting plates are fixedly connected to both ends of the top side of the base. Turntables are rotatably connected to adjacent sides of the connecting plates at both ends. Mounting plates are fixedly connected to adjacent sides of the turntables at both ends. An electric fan body is mounted on the front side of the mounting plate. A mounting ring is fixedly connected to the rear end of the outer wall of the electric fan body. A protective frame is connected to the mounting ring via multiple mounting components. A rotating component is located on the left side of the turntable at the left end. An air spring is rotatably connected to the left end of the top side of the base.

[0007] Furthermore, the mounting assembly includes a mounting rod, the front end of which is rotatably connected to a second rotating shaft, the second rotating shaft being fixedly connected to the rear end of the protective frame, and a fixing block being fixedly connected to the rear end of multiple mounting rods on adjacent sides.

[0008] Furthermore, the outer wall of the mounting ring is provided with multiple mounting grooves, and the rear ends of the multiple mounting grooves on the adjacent sides are provided with fixing grooves. The adjacent ends of the multiple mounting rods are located inside the mounting grooves, and the fixing block is located inside the fixing groove.

[0009] Furthermore, an upper fixing ring is provided at the front end of the outer wall of the electric fan body, and a lower fixing ring is connected to the left end of the bottom side of the upper fixing ring through a rotating shaft. The left end of the upper fixing ring and the left end of the lower fixing ring are connected by a buckle.

[0010] Furthermore, multiple limiting grooves are provided on the adjacent sides of the upper fixing ring and the lower fixing ring, and the opposite ends of the multiple mounting rods are located inside the limiting grooves.

[0011] Furthermore, the rotating assembly includes a rotating rod, the right end of which is fixedly connected to the left side of the left turntable, the left end of which passes through the left connecting plate and is fixedly connected to a connecting block, and a sliding groove is provided at the bottom of the connecting block.

[0012] Furthermore, a slide rod is fixedly connected to the drive end of the pneumatic rod, and the slide rod is slidably connected inside the slide groove.

[0013] Furthermore, a limit block is fixedly connected to the right side of the slide rod.

[0014] This utility model has the following beneficial effects:

[0015] In this invention, when the protective frame needs to be disassembled, the latches are opened to release the restriction on the upper and lower fixing rings. Then, rotating the shaft separates the upper and lower fixing rings for disassembly, thereby releasing the restriction on the mounting rod. Next, rotating another shaft drives the mounting rod to rotate, causing the fixing block to disengage from the fixing groove, thus completing the disassembly of the protective frame. The entire process requires no tools, saving time and reducing maintenance difficulty.

[0016] In this invention, the user can easily control the rotation direction of the electric fan body simply by rotating the air rod. When the air rod extends, the connected sliding rod moves accordingly. When the sliding rod touches the edge of the sliding groove, it pushes the connecting block and the rotating rod to rotate, thereby driving the turntable, mounting plate, and electric fan body to rotate synchronously, achieving multi-angle airflow. This design is easy to operate, greatly meeting people's diverse needs for airflow direction in different scenarios and significantly improving the user experience. Attached Figure Description

[0023] 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.

[0024] Reference Figure 1 , Figure 2 and Figure 4This utility model provides an embodiment of an electric fan with a tool-free protective frame, comprising a base 1, with connecting plates 4 fixedly connected to both ends of the top side of the base 1, turntables 5 rotatably connected to adjacent sides of the connecting plates 4, and mounting plates 6 fixedly connected to adjacent sides of the turntables 5. An electric fan body 9 is mounted on the front side of the mounting plate 6, and a mounting ring 14 is fixedly connected to the rear end of the outer wall of the electric fan body 9. The mounting ring 14 is connected to a protective frame 7 via multiple mounting rods 17. A rotating rod 21 is provided on the left side of the left turntable 5, and an air rod 18 is rotatably connected to the left end of the top side of the base 1. A rotating shaft 16 is rotatably connected to the front end of the mounting rod 17, and the rotating shaft 16 is fixedly connected to the rear end of the protective frame 7. Multiple mounting rods 17 are also provided. A fixing block 15 is fixedly connected to the rear end of each rod 17 on the same side. Multiple mounting grooves 11 are provided on the outer wall of the mounting ring 14. Fixing grooves 12 are provided on the rear end of each mounting groove 11 on the same side. The ends of each mounting rod 17 are located inside the mounting grooves 11. The fixing block 15 is located inside the fixing groove 12. An upper fixing ring 22 is provided at the front end of the outer wall of the electric fan body 9. The left end of the bottom side of the upper fixing ring 22 is connected to a lower fixing ring 23 through a rotating shaft 8. The left ends of the upper fixing ring 22 and the lower fixing ring 23 are connected by a buckle 13. Multiple limiting grooves 10 are provided on the same side of the upper fixing ring 22 and the lower fixing ring 23. The ends of each mounting rod 17 are located inside the limiting grooves 10.

[0025] Specifically, when the protective frame 7 needs to be disassembled, this electric fan can be operated without tools. The user simply needs to open the clip 13 to release the restriction on the upper fixing ring 22 and the lower fixing ring 23. Then, rotating the first shaft 8 separates the upper fixing ring 22 and the lower fixing ring 23, thereby releasing the restriction on the mounting rod 17. Next, rotating the second shaft 16 rotates the mounting rod 17, causing the fixing block 15 to disengage from the fixing groove 12. This easily achieves tool-free disassembly of the protective frame 7.

[0026] Reference Figure 3 and Figure 4 The right end of the rotating rod 21 is fixedly connected to the left side of the left turntable 5. The left end of the rotating rod 21 passes through the left end connecting plate 4 and is fixedly connected to the connecting block 3. The bottom of the connecting block 3 is provided with a sliding groove 2. The driving end of the air rod 18 is fixedly connected to the sliding rod 19. The sliding rod 19 is slidably connected inside the sliding groove 2. The right side of the sliding rod 19 is fixedly connected to the limit block 20.

[0027] Specifically, in use, simply rotating the air rod 18 allows for flexible control of the rotation direction of the electric fan body 9. Simultaneously, extending the air rod 18 pushes the slide rod 19 to move. When the slide rod 19 moves to the edge of the slide groove 2, the resulting thrust causes the connecting block 3 and the rotating rod 21 to rotate synchronously. As the rotating rod 21 rotates, the turntable 5, the mounting plate 6, and the electric fan body 9 also rotate, thereby achieving precise adjustment of the blowing angle of the electric fan body 9.

[0028] Working principle: During use, the rotation direction of the electric fan body 9 can be controlled by rotating the air rod 18. Then, the air rod 18 is extended to push the slide rod 19 to move. When the slide rod 19 moves to the edge of the slide groove 2, it will push the connecting block 3 and the rotating rod 21 to rotate, thereby driving the turntable 5, the mounting plate 6 and the electric fan body 9 to rotate. This allows the blowing angle of the electric fan body 9 to be adjusted. When it is necessary to disassemble the protective frame 7, the buckle 13 is opened to release the limit on the upper fixing ring 22 and the lower fixing ring 23. Then, the rotating shaft 18 is rotated to separate and disassemble the upper fixing ring 22 and the lower fixing ring 23, thereby releasing the limit on the mounting rod 17. Then, the rotating shaft 26 is rotated to drive the mounting rod 17 to rotate and make the fixing block 15 leave the inside of the fixing groove 12. Thus, the protective frame 7 can be disassembled without tools.

[0029] 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.
