[0020] like Figures 1-5The portable floor fan shown includes a fan body 1 and a support frame 2 for supporting the fan body 1. The fan body 1 and the support frame 2 are detachable. Supporting pivots 3 are provided on both the left and right sides of the fan body 1. The support frame 2 includes a U-shaped ground support frame 4 and two vertical support rods 5 hinged at both ends of the ground support frame 4. An angle support assembly is connected between the ground support frame 4 and the vertical support rods 5. The angle support assembly is used to fix the ground support frame 4 and the vertical support rods 5 so that they are kept in an open state. A U-shaped block 6 is provided at the upper end of the vertical support rod 5. The support pivots 3 at both ends are placed in the U-shaped slots 7 of the two U-shaped blocks 6.

[0021] According to the above structure, firstly, the fan body 1 and the support frame 2 are detachably connected. Then, the ground support frame 4 and the vertical support rod 5 of the support frame 2 are hinged, so that the two can be folded and stored, which facilitates packing during transportation. The space occupied by the disassembled packing is small, which reduces transportation costs.

[0022] See Figure 1 , Figure 2 , Figure 4 As shown, the U-shaped slot 7 of one of the U-shaped blocks 6 faces the front of the fan body 1, and the U-shaped slot 7 of the other U-shaped block 6 faces the back of the fan body 1. Thus, when the fan body 1 is connected and installed to the support frame 2, the U-shaped slots 7 of the two U-shaped blocks 6 are inserted into the support shaft 3 by swinging the vertical support rod 5. Since the U-shaped slots 7 of the two U-shaped blocks 6 are arranged opposite each other, the fan body 1 can be firmly fixed when the vertical support rod 5 is fixed. The structure is simple and the installation is convenient.

[0023] See Figure 3 As shown, the outer end of the support shaft 3 is provided with a threaded locking knob 31. The locking knob 31 is provided with a pressing part 32. The pressing part 32 presses the U-shaped block 6 by rotating the locking knob 31. The blowing angle of the fan body 1 can be adjusted by rotating the support shaft 3. Then, the locking knob 31 can be tightened directly to fix the support shaft 3 and the fan body 1.

[0024] See Figure 2 As shown, the ground support frame 4 includes a horizontal bar 41 and a horizontal bar 42 located at both ends of the horizontal bar 41. The vertical support rod 5 is hinged to the horizontal bar 42. The horizontal bar 41 and the horizontal bar 42 are made of metal in one piece.

The outer end of the diagonal brace 51 can support and abut against the support seat 52, thereby keeping the vertical brace 5 and the horizontal rod 42 in an open state at an angle, and the screw 54 can be screwed into the threaded hole 53.

[0026] The working principle of the angle support assembly is as follows: by swinging the diagonal brace 51, one end of the diagonal brace 51 is supported on the support base 52. Then, the screw 54 is screwed into the threaded hole 53 of the support base 52, so as to achieve a fixed connection between the vertical brace 5, the diagonal brace 51 and the horizontal bar 42.

[0027] Furthermore, a notch 61 is provided on one side of the diagonal brace 51, and a plurality of notches 62 are provided on the outer wall surface of the screw 54. The notches 62 are located in the notch 61, so that a wrench can be inserted into the notch 62 to tighten the screw 54.

[0028] See Figure 2 As shown, a motor mounting housing 71 is provided on the rear side of the fan body 1, and a handle 72 is provided on the motor mounting housing 71.
