[0002] A fan is a device that generates wind to keep you cool on hot days. An electric fan is a device that uses electricity to generate airflow. The fan inside is powered on and then rotates to generate natural wind to keep you cool. A rechargeable fan is a mini version of a fan that is small in size and can be carried.

[0003] Currently, there are two types of small fans: handheld and desktop, but they cannot be switched. At the same time, due to the fixed structure of the fan when carried, the carrying and display area is still relatively large. At the same time, the existing small fans generally use the method of loosening or tightening bolts to adjust the grid guide leaves. The adjustment process is difficult to control and inconvenient to operate. In addition, the disassembly and installation of traditional small rechargeable fans are relatively troublesome. Therefore, we propose a portable handheld foldable rechargeable fan. Utility Model Content

At this time, the grid diversion turning leaf cannot rotate, and the diversion control cover is pressed again. At this time, the V-shaped buckle position and the hook are disengaged, and the pressing column is pushed to pop out and reset under the action of the pressing column rebound spring. At this time, the anti-rotation rib is disengaged from the inner cavity of the turning leaf tooth groove. At this time, the grid diversion turning leaf will not be limited and can automatically rotate under the action of wind force. Repeated pressing can realize the switch control of the fan leaf front cover, which is simple and convenient to operate and has a wider blowing area. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The coordinated use of the buckle 16 and the slot 13 makes it more convenient to install and disassemble the wind blade front cover 17. During operation, the front end of the wind blade front cover 17 is sleeved into the inner cavity of the wind blade rear cover 8, and then the wind blade front cover 17 is rotated to make the buckle 16 and the slot 13 jammed to achieve fixation. When removing, the wind blade front cover 17 is rotated in the opposite direction to disengage the buckle 16 from the slot 13, and the wind blade front cover 17 can be directly pulled out, which is convenient for disassembly and installation, cleaning, maintenance and other operations.

[0032] The middle part of the wind vane front cover 17 is fixedly connected with a guide quick opening control assembly mounting seat 23, the inner cavity of the guide quick opening control assembly mounting seat 23 is installed with a guide quick opening control assembly, and the guide quick opening control assembly is connected to the guide quick opening control assembly mounting seat 23 by screws.

[0033] The inner cavity of the wind leaf front cover 17 is rotatably connected to the grid guide turning leaf 18, the middle part of the grid guide turning leaf 18 is fixedly connected to the mounting tube 19, the interior of the mounting tube 19 is fixedly connected to the positioning ring 20, the surface of the positioning ring 20 is provided with a turning leaf tooth groove 30, the surface of the mounting tube 19 is movably sleeved with a guide quick-opening control cover 21, the inner wall of the guide quick-opening control cover 21 is fixedly connected to a stop rib 29, and the stop rib 29 is adapted to the turning leaf tooth groove 30.

[0034] The diversion quick-opening control cover 21 is connected to the diversion quick-opening control assembly through screws, and a diversion control cover plate 22 is provided on one side of the diversion quick-opening control cover 21 .

[0035] The diversion quick-opening control component includes a base 24, a pressing column rebound spring 25, a pressing column 26, a V-shaped buckle position 27 and a hook 28. The pressing column 26 passes through the inner cavity of the diversion quick-opening control component mounting seat 23 and is connected to the diversion quick-opening control cover 21 by screws. The pressing column 26 is movably sleeved into the inner cavity of the base 24. The inner cavity of the base 24 is connected with the pressing column rebound spring 25.

At this time, the V-shaped buckle 27 and the hook needle 28 are disengaged, and the hook needle 28 will move downward along the end surface of the disengaged inclined block 31. Deformation will occur during the movement. At the same time, under the influence of the inclined panel, one end of the hook needle 28 will move outward, and then move to the bottom of the disengaged inclined block 31. After moving to the bottom of the disengaged inclined block 31, the end of the hook needle 28 will contact the pressing column 26 again. After releasing the diversion control cover 22, the pressing column 26 is pushed to pop out and reset under the action of the pressing column rebound spring 25, and the end of the hook needle 28 moves along the bottom of the inclined panel to recover. At this time, the anti-rotation rib 29 is disengaged from the inner cavity of the turning leaf tooth groove 30. At this time, the grid diversion turning leaf 18 will not be limited, and can automatically rotate under the action of wind force. Repeatedly pressing the diversion control cover 22 can realize the switch control of the wind leaf front cover 17. The operation is simple and convenient, and the blowing area is wider.

[0037] A folding bracket rear cover 11 is mounted on the back of the folding bracket front cover 9 by screws, and a back label 12 is pasted on the back of the folding bracket rear cover 11 .

[0038] The inner cavity of the upper cover 4 is provided with a battery 2 and a control circuit board 3. One end of the upper cover 4 is connected to a control mask 5. The control mask 5 is provided with a switch button 6. The wind force can be controlled by the switch button 6 and the control circuit board 3 to achieve multi-gear adjustment.
