[0023] The present invention will be further described below with reference to the accompanying drawings:
[0024] like Figures 1-9 As shown, a folding fan with a retractable protective cover mainly consists of a handle shell 1, a fan blade plate frame assembly 2, a single-sided retractable cover 3, and a U-shaped groove sliding sleeve 7.
[0025] The fan blade plate bracket assembly 2 is equipped with a top U-shaped groove bracket 8 and a bottom U-shaped groove bracket 9 on its upper and lower sides respectively. The top side of the handle housing 1 is provided with a flip protrusion 14. The bottom end of the bottom U-shaped groove bracket 9 is installed on the flip protrusion 14 through the flip bracket 13, so as to realize the flip folding of the handle and its top structure.
[0026] Both sides of the top U-shaped trough frame 8 are connected to a single-sided retractable cover 3 via a cover-side connecting line 5, and the other side of the single-sided retractable cover 3 is attached to the bottom U-shaped trough frame 9.
[0027] The single-sided retractable cover 3 is composed of several U-shaped rods 31. Two adjacent U-shaped rods 31 are connected together by rod connecting ropes 32. The opening of the U-shaped rod 31 is provided with a groove rotating shaft 33. The front and rear sides of the fan blade plate frame assembly 2 are provided with inclined grooves 10, with two grooves on each side and symmetrically arranged. The groove rotating shaft 33 is rotatably installed into the inclined groove 10. The lengths of the several U-shaped rods 31 are different, so that the sides are circularly distributed after unfolding.
[0028] The handle housing 1 has sliding limit grooves 12 on both sides. The bottom of the U-shaped groove slide sleeve 7 is connected to the slide sleeve ear 16. The inner side of the slide sleeve ear 16 is equipped with an ear cylinder 17. The ear cylinder 17 extends into the sliding limit groove 12, so that the U-shaped groove slide sleeve 7 fitted on the handle housing 1 can slide upward to fold up the single-sided retractable cover 3 and then flip and fold it.
[0029] A limit plate 4 is fixedly installed on the front side of the fan blade plate bracket assembly 2.
[0030] like Figures 1-9 As shown, this utility model also discloses the following more optimized specific structures:
[0031] The flipping frame 13 is mounted to the flipping protrusion 14 by flipping fastening bolts 15.
[0032] Both the single-sided storage cover 3 and the bottom U-shaped groove frame 9 are equipped with embedded magnetic blocks 6, which are used to attract and retract the storage and unfold the fixed structure.
[0033] The fan blade plate bracket assembly 2 consists of a plate bracket connecting shaft 22 and side plate brackets 21 rotatably mounted to both ends of the plate bracket connecting shaft 22. Fan blades 19 are mounted on the plate bracket connecting shaft 22. The upper and lower ends of the side plate brackets 21 are fixedly mounted together with the top U-shaped groove bracket 8 and the bottom U-shaped groove bracket 9, respectively. One end of the plate bracket connecting shaft 22 extends to the back side of the side plate bracket 21 and is connected to the fan motor 23. The fan motor 23 is fixed to the side plate bracket 21 by a support frame.
[0034] The limiting plate 4 is a T-shaped plate, which is fixedly installed on the fan blade plate frame 2 by the limiting plate screw 18.
[0035] The handle housing 1 has a battery assembly installed inside. The side of the handle housing 1 has a charging port 11, and the back of the handle housing 1 has a switch groove (not shown). The switch groove is used to install a switch for easy control of the fan blade rotation.
[0036] like Figures 1-9 The protective cover shown is retractable. The foldable fan can be flipped to the back of the handle shell 1 by the flipping frame 13. The fan blade plate frame 2, the single-sided retractable cover 3, the top U-shaped groove frame 8, and the bottom U-shaped groove frame 9 can be flipped. Before flipping, the U-shaped groove slide sleeve 7 is slid upward. The single-sided retractable cover 3 overcomes the attraction force and is retracted into the U-shaped groove of the U-shaped groove slide sleeve 7. Then it is flipped together, making the retraction and folding more thorough.
[0037] Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of this utility model as claimed.
