[0021] The following detailed description of the application in conjunction with the drawings, it is necessary to point out here that the following detailed description only for the further description of the application, can not be understood as the limitation of the scope of the application, the skilled in the art can make some non-essential improvements and adjustment to the application according to the above application content.

[0022] Refer to the description attached Figures 1-7The utility model provides a multi -head fan, including fan support 1, a plurality of fan heads 2 are installed on fan support 1, and fan head 2 includes the installation cylinder 21 installed on fan support 1, and the one end fixed mounting of installation cylinder 21 has fixed disc 22, and the one side of fixed disc 22 is slidably arranged with shell 23, and the inside of shell 23 is installed with fan assembly 20, and the side of shell 23 away from fixed disc 22 is provided with elastic sheet 24, and elastic sheet 24 is fixed on fixed disc 22, and the side of shell 23 close to elastic sheet 24 is provided with a plurality of recesses 231, and the side of elastic sheet 24 close to shell 23 is provided with convex part 241, and convex part 241 is clamped in the inside of corresponding recess 231.

[0023] It should be noted that the fan assembly 20 includes a fan and a motor, and the motor drives the fan to rotate to perform air supply.

[0024] In the embodiment, as shown in Figure 4 and Figure 5 , the convex part 241 is clamped in the inside of the recess 231. When adjusting the angle of the fan head 2, the shell 23 is pulled upward or downward, and the fixed disc 22 and the elastic sheet 24 remain stationary. At this time, the recess 231 moves relative to the convex part 241. When the shell 23 is rotated to the appropriate position, the convex part 241 is clamped into the inside of the corresponding recess 231, thereby achieving the purpose of adjusting the angle of the fan head 2. The elastic sheet 24 can be made of plastic or metal.

[0025] The above technical solution achieves the purpose of adjusting the angle of the fan head 2 upward or downward by rotating the shell 23 relative to the elastic sheet 24, clamping the convex part 241 into the corresponding recess 231 to fix the shell 23 at the adjusted angle position. When adjusting, only the fan head 2 needs to be pulled in the desired direction, which is convenient to operate.

[0026] In the embodiment, as shown in Figure 1 and Figure 2 , the fan support 1 includes a base 11, a plurality of groups of vertical rods 12 and joint rods 13 are installed on the base 11, and adjacent vertical rods 12 and joint rods 13 are inserted and fixed with each other.

[0027] It should be noted that the installation cylinder 21 is installed on the joint rod 13, and by setting different numbers of vertical rods 12 and joint rods 13, different numbers of fan heads 2 can be set, which has strong selectivity.

[0028] In the embodiment, as shown in Figures 2-6 , the installation cylinder 21 is rotatably sleeved on the outside of the joint rod 13.

[0029] Further, a sliding groove 131 is formed on the outer sidewall of the joint rod 13, and a sliding block 211 is fixed on the inner sidewall of the installation cylinder 21, and the sliding block 211 slides in the inside of the sliding groove 131.

[0030] It should be noted that, by rotating the mounting cylinder 21 outside the adding rod 13, the horizontal rotation of the fan head 2 can be realized, and the air supply range of the fan head 2 can be increased.

[0031] In the embodiment, as shown in the figure, the middle part of the chute 131 has two outward protruding side protrusions 132, and the sliding block 211 is clamped and fixed with the side protrusions 132 when located between the two side protrusions 132. Figure 7

[0032] It should be noted that, when rotating the mounting cylinder 21, the mounting cylinder 21 can be freely rotated when the sliding block 211 is located outside the two side protrusions 132, and when the sliding block 211 is rotated from outside the two side protrusions 132 to between the two side protrusions 132, the sliding block 211 will be extruded with the side protrusions 132, and the operator's hand will be fed back, so that it can be judged that the sliding block 211 is rotated to between the two side protrusions 132, that is, the state of the fan head 2 is returned to normal.

[0033] The above-mentioned embodiments only express several implementation manners of the utility model, and the description is more specific and detailed, but it cannot be understood as the limitation of the patent range of the utility model. It should be noted that, for ordinary skilled persons in the art, without departing from the concept of the utility model, a number of modifications and improvements can be made, which belong to the protection range of the utility model.​
