[0023] Example: An adjustable handheld fan, such as Figures 1-8 As shown, the device includes a body 1, a shell 2, an electric fan 3, a connector 4, a mounting base 6, a charging port 7, an adjustment button 8, and a fixing assembly. The mounting base 6 is bonded to the upper inner area of ​​the body 1. The connector 4 is mated to the mounting base 6. The lower part of the shell 2 has a sliding groove 5, and the shell 2 is rotatably mounted on the connector 4 through this sliding groove 5. The spherical surface at the bottom of the shell 2 forms a sliding contact with the body 1. In the initial state, the connector 4 is located at the foremost position of the sliding groove 5, so that the shell 2 can only rotate upward along the connector 4. The electric fan 3 is bolted to the inside of the shell 2. The air outlet on the front of the shell 2 is connected to the back... The air intakes on all surfaces feature a floral design, which not only enhances aesthetics but also effectively increases the contact area with air, optimizes airflow distribution, and improves both blowing and suction effects. The charging port 7 is located on the upper rear side of the body 1, and the adjustment button 8 is located on the other front side of the upper part of the body 1 and is electrically connected to the electric fan 3. The adjustment button 8 consists of two independent buttons: the left button is the power control button, responsible for turning the power system of the electric fan 3 on or off, and the right button is the fan speed adjustment button, responsible for precisely controlling the speed of the electric fan 3. The fixing components are located at the lower end of the body 1.

[0024] like Figure 1 , Figure 2 , Figure 3 , Figure 6 , Figure 7 and Figure 8 As shown, the fixing assembly includes a connecting block 9, a suction cup 12, and a slider 13. The connecting block 9 is bonded to the lower end of the body 1. Two limiting grooves 10 are arranged side by side on the front and rear inner sidewalls of the connecting block 9. Each limiting groove 10 consists of a horizontal part and a vertical part. Two exhaust grooves 11 are arranged side by side on the left and right sides of the connecting block 9. A slider 13 is slidably installed inside each limiting groove 10. The suction cup 12 is bonded between the two sliders 13 and forms a sliding contact with the connecting block 9. Two ventilation grooves 14 are arranged side by side on the upper part of the suction cup 12 and directly connect to the internal space of the suction cup 12. The exhaust grooves 11 and ventilation grooves 14 have the same size.

[0025] In the use of handheld fan, the user can adjust the wind flow angle of the electric fan 5 according to the flexible needs of the user, and the specific adjustment steps are as follows: the user rotates the shell 2 upwards, and when the shell 2 is rotated to 30 degrees, the connecting piece 4 reaches the last position of the sliding groove 5, thereby limiting the rotation of the shell 2 to stop, and realizing the adjustment of the wind flow angle of the electric fan 5.

[0026] In the use of the fixed assembly, initially, the sliding block 13 is located in the horizontal part of the limiting groove 10, and the top end of the sliding block 13 is in contact with the topmost end of the horizontal part of the limiting groove 10 (a magnetic layer can be arranged on the contact surface to enhance the stability of the contact between the sliding block 13 and the topmost end of the horizontal part of the limiting groove 10), at this time, the air inlet groove 14 and the air outlet groove 11 are staggered with each other, and the inside of the suction cup 12 is in a negative pressure state and has a certain adsorption capacity; when using the handheld fan indoors, the user can directly place the machine body 1 on the table, and after placing, press the suction cup 12 downward, so as to make the air in the suction cup 12 further discharge, and under the action of the external atmospheric pressure, the suction cup 12 will be tightly adsorbed on the table, thereby firmly fixing the machine body 1 and freeing the user's hands to facilitate other operations; when the user needs to pick up the machine body 1, the user first presses the machine body 1 downward, so that the bottom end of the sliding block 13 contacts the bottommost end of the horizontal part of the limiting groove 10 (after the contact, the user can clearly perceive that the downward movement of the machine body 1 in the vertical direction has been terminated), and then immediately rotate the machine body 1 clockwise by 90 degrees, the connecting ring 2 is synchronously rotated clockwise by 90 degrees, thereby adjusting the angle of the limiting groove 10, so that the vertical part of the limiting groove 10 is aligned with the sliding block 13, and after alignment, continue to press the machine body 1 downward, the sliding block 13 will slide into the vertical part of the limiting groove 10 under the action of the pressure, until the top end of the sliding block 13 contacts the topmost end of the vertical part of the limiting groove 10, at this time, the air outlet groove 11 is aligned and communicated with the air inlet groove 14, and the outside air can enter the inside of the suction cup 12, so that the internal pressure of the suction cup 12 is balanced with the outside, and the adsorption force disappears, at this time, the user can easily pick up the machine body 1 from the table.

[0027] It should be noted that the structure of the sliding groove 5 is specially designed to ensure that when the shell 2 is rotated upwards to 30 degrees, the connecting piece 4 can accurately reach the last position of the sliding groove 5, thereby accurately limiting the angle adjustment.
