[0023] The utility model will be further explained in detail in combination with the drawings.

[0024] Referring to Figures 1-6 and Figure 8 A multifunctional handheld fan, including fan head 1, handle 2 and clamping device 3, handle 2 is located below fan head 1, fan head 1 includes front cover 11, fan blade 12 and rear cover 13, front cover 11 and rear cover 13 cooperate, and fan blade 12 is located between front cover 11 and rear cover 13, and rear cover 13 is equipped with installation groove 131, and clamping device 3 includes mounting seat 31 and clamping block 32, clamping block 32 is equipped on mounting seat 31, and the bottom of mounting seat 31 is formed with installation head 311, installation head 311 cooperates with installation groove 131, the inner wall of installation groove 131 is equipped with protruding 132, and the outer periphery of installation head 311 is equipped with screw-in groove 312, and screw-in groove 312 cooperates with protruding 132, wherein, the working principle of fan head 1 is same with the working principle of existing handheld fan, and the fixed mode of front cover 11 and rear cover 13 is prior art, which will not be repeated here.

[0025] ​The installation groove 131 is a circular groove formed on the back of the rear cover 13. The installation head 311 is circular, which is convenient to rotate after being matched with the installation groove 131, and is convenient to be screwed into the slot 312 to rotate to the protrusion 132, so that the protrusion 132 is clamped into the slot 312, thereby realizing the fixation of the installation head 311 in the installation groove 131, that is, the installation of the mounting seat 31.

[0026] When the mounting seat 31 is fixed on the installation groove 131, the clamping device 3 can be clamped and fixed on the umbrella handle or other structures, which is convenient to carry the multifunctional handheld fan when going out, and is convenient to hold or clamp the fan, thereby meeting different use requirements.

[0027] The outer side of the installation head 311 is provided with a notch 313, which is located on one side of the slot 312 and is in communication with the slot 312, and the notch 313 penetrates the bottom end of the installation head 311. By being provided with the notch 313, an empty space is formed with the protrusion 132, which is convenient to insert the notch 313 to the protrusion 132, and is convenient to insert the installation head 311 into the installation groove 131. Then, the mounting seat 31 is rotated again, so that the protrusion 132 is clamped into the slot 312, thereby realizing the cooperation and fixation of the installation head 311 and the installation groove 131. When the clamping device needs to be taken out, the mounting seat is separated from the installation groove by reversing the rotation of the mounting seat so that the notch 313 is rotated to the protrusion.

[0028] In order to prevent the clamping device 3 from being separated from the installation groove 131 during use, a limiting column 133 is formed on the inner wall of the installation groove 131. The limiting column 133 is located below the protrusion 132, and the outer wall of the installation head 311 is provided with a limiting groove 314, which is located above the slot 312. The limiting groove 314 can cooperate with the limiting column 133.

[0029] Specifically, as the mounting seat 31 is gradually rotated to the side of the protrusion 132, the protrusion 132 is clamped into the slot 312. When the limiting groove 314 is rotated to the limiting column 133, the limiting column 133 is clamped into the limiting groove 314. Through the cooperation of the limiting column 133 and the limiting groove 314, the further rotation of the mounting seat 31 can be prevented, thereby effectively avoiding the directional rotation of the mounting seat 31, preventing the separation of the mounting seat 31 from the rear cover 13 during use, and ensuring that the clamping device 3 can be tightly fixed on the rear cover 13.

[0030] The protrusion 132 is two and is evenly distributed on the inner wall of the installation groove 131. The slot 312 is correspondingly provided with two protrusions 132, thereby improving the stability of the combination of the mounting seat 31 and the installation groove 131, and improving the uniformity of the force.

[0031] The top of the mounting base 31 is provided with a first clamping plate 315, the mounting base 31 is provided with a containing groove 316, one end of the clamping block 32 is located in the containing groove 316, the other end extends out after penetrating through the mounting base 31, the top of the one end of the clamping block 32 is provided with a second clamping plate 321, and the second clamping plate 321 is oppositely arranged with the first clamping plate 315. The first clamping plate 315 is in an integral molding structure with the mounting base 31, and the second clamping plate 321 is in an integral molding structure with the clamping block 32.

[0032] The clamping device 3 further comprises a compression spring 33, one end of the compression spring 33 is in abutment with the side wall of the containing groove 316, the other end is in abutment with the clamping block 32, and the length direction of the compression spring 33 is consistent with the moving direction of the clamping block 32. In use, an external force acts on the clamping block 32, so that the distance between the second clamping plate 321 and the first clamping plate 315 increases, so that the umbrella handle can be clamped between the first clamping plate and the second clamping plate; when the umbrella handle is inserted, the external force is removed, the clamping block 32 is pushed under the rebounding force of the compression spring 33, the second clamping plate 321 moves to the side of the first clamping plate 315, so that the umbrella handle can be clamped by the two clamping plates; and the rebounding force of the compression spring 33 enables the second clamping plate 321 to maintain the clamping state of the umbrella handle. When the clamping device 3 needs to be separated from the umbrella handle, an external force acts on the clamping block 32, driving the second clamping plate 321 to move away from the first clamping plate, so that the distance between the two increases, facilitating separation from the umbrella handle.

[0033] In actual use, in order to improve the clamping effect of the two clamping plates on the umbrella handle, anti-skid pads are pasted on the opposite sides of the first clamping plate and the second clamping plate. Through the anti-skid pads, the friction between the two and the umbrella handle can be increased, effectively preventing sliding.

[0034] The two sides of the containing groove 316 are provided with limiting blocks 317, and the limiting blocks 317 are located between the first clamping plate 315 and the second clamping plate 321. The limiting blocks 317 and the mounting base 31 are in an integral molding structure. Through the limiting blocks 317, the moving position of the second clamping plate 321 can be limited; specifically, when the umbrella handle is taken out from between the first clamping plate and the second clamping plate, the external force is removed, the second clamping plate 321 is pushed to be close to the first clamping plate under the action of the compression spring, so that the distance between the two gradually decreases; when the second clamping plate 321 abuts against the limiting block 317, at this time, the distance between the two clamping plates is small, and the limiting block 317 limits the second clamping plate 321 to prevent the second clamping plate 321 from continuing to move.

[0035] Due to the limiting block 317, the second clamping plate 321 cannot move to the edge position of the accommodating groove 316, so that the side wall of the second clamping plate 321 is in contact with the side wall of the accommodating groove 316, that is, the surface-to-surface contact is realized, and therefore, when the clamping block moves, the surface-to-surface guiding movement is more stable, avoiding the clamping block from being stuck or inclined when point contact occurs, thereby benefiting the service life of the entire clamping device.

[0036] The side wall of the accommodating groove 316 is provided with a first clamping groove 318, one end of the clamping block 32 is provided with a second clamping groove 322, one end of the compression spring 33 is located in the first clamping groove 318, and the other end is located in the second clamping groove 322. Therefore, through the first clamping groove 318 and the second clamping groove 322, the two ends of the compression spring 33 can be conveniently inserted into the two clamping grooves, thereby facilitating the installation of the compression spring 33.

[0037] The top end of the mounting seat 31 is provided with a first baffle 319, and the top of the other end of the clamping block 32 is provided with a second baffle 323. The first baffle 319 and the first clamping plate 315 are located at both ends of the accommodating groove 316, respectively. By providing the first baffle 319 and the second baffle 323, when an external force acts on the clamping block 32, it can be placed on the first baffle 319 and the second baffle 323, facilitating the pressing of the hand.

[0038] As shown in Figure 1 and Figure 7 The multifunctional handheld fan further comprises a supporting seat 4, and the bottom of the handle 2 can be inserted into the supporting seat 4. The supporting seat 4 is provided with a insertion hole 41, and the bottom of the handle 2 is inserted into the insertion hole 41. The handheld fan is supported by the supporting seat 4, and the handheld fan can be placed on a desktop or other panel. In order to facilitate the fastening of the insertion hole 41 and the handle 2, a guide column 42 is formed on the inner wall of the insertion hole 41. The outer diameter of the guide column 42 gradually increases from top to bottom, so that the handle 2 is gradually pressed by the guide column 42 when it is inserted into the insertion hole 41, and the handle and the supporting seat 4 are combined stably.

[0039] The above is only a preferred embodiment of the utility model, and it should be pointed out that for ordinary skilled persons in the art, without departing from the creative concept of the utility model, a number of modifications and improvements can be made, which all belong to the protection scope of the utility model.
