[0031] Embodiment

[0032] As Figures 1-4 shown, a portable electric fan proposed by the present utility model includes a rod body 1, a base 2, and a fan head 3. It further includes a pulley 7 slidably installed at the bottom of the base 2, and a moving component for driving the pulley 7 to move is provided on the base 2. The moving component includes a first pressing ring 4 slidably installed on the top of the base 2. An anti-slip sleeve 15 is fixedly installed on the rod body 1, and the anti-slip sleeve 15 can be held when the electric fan is moved to prevent the electric fan from tipping over.

[0033] Among them, the base 2 is an annular plate with a cavity opened at the bottom. A connecting plate 201 is fixedly installed at the bottom of the base 2. The connecting plate 201 is used to increase the contact area between the electric fan and the ground when it is not moving, thereby improving the stability of the electric fan. At least two groups of sliding seats 6 are fixedly installed in the cavity at the bottom of the base 2, and the pulley 7 is slidably installed in the sliding seats 6.

[0034] In this embodiment, the moving component further includes a moving block 8 slidably installed in the sliding seat 6. A pulley 7 is provided at the bottom of the moving block 8. A sliding rod 9 passing through the base 2 is fixedly installed at the top of the moving block 8. The sliding rod 9 is fixedly connected to the first pressing ring 4. A plurality of first springs 10 are fixedly connected between the base 2 and the first pressing ring 4. The first springs 10 are respectively sleeved outside the sliding rod 9. When the first pressing ring 4 is squeezed, the sliding rod 9 moves downward, causing the moving block 8 fixedly installed at the bottom of the sliding rod 9 and the pulley 7 to move downward, so that the pulley 7 contacts the ground.

[0035] As Figure 3 shown, fixed plates 12 are fixedly installed on both sides of the top of the base 2. A rotating rod is rotatably installed at the top of the fixed plate 12. A limiting rod 11 is fixedly installed at the top of the rotating rod. Rotating the limiting rod 11 causes one end of the limiting rod 11 to rotate above the first pressing ring 4, thereby limiting the first pressing ring 4.

[0036] In this embodiment, the supporting component includes a supporting plate 144. The supporting component further includes mounting boxes 14 fixedly installed on both sides of the sliding seat 6. A sliding block 141 is slidably installed in the mounting box 14. A sliding groove 142 for the sliding block 141 to slide is formed in each of the mounting boxes 14. The supporting plates 144 are respectively fixedly installed on one side of the bottom of the sliding block 141 away from the pulley 7. When the second pressing ring 5 moves downward, the connecting rod 13 also moves downward, thereby driving the sliding block 141 in the mounting box 14 to move downward in the sliding groove 142, so that the supporting plate 144 fixedly connected to the bottom of the sliding block 141 contacts the ground downward, thereby lifting the base 2, increasing the contact area between the electric fan and the ground, and preventing the electric fan from tipping over.

[0037] Wherein, a second spring 143 is fixedly connected between the sliding block 141 and the mounting box 14. The second spring 143 is sleeved outside the connecting rod 13. A connecting rod 13 is fixedly installed at one end of the sliding block 141 located in the mounting box 14. The connecting rod 13 passes through the base 2 and is fixedly installed with a second pressing ring 5 at one end of the first pressing ring 4. Through holes for the connecting rod 13 to slide are formed in both the base 2 and the first pressing ring 4. Releasing the first pressing ring 4 and the second pressing ring 5, the second pressing ring 5 is reset upward under the action of the second spring 143, causing the sliding block 141 and the supporting plate 144 to move upward. The supporting plate 144 leaves the ground, which does not affect the pulley 7 to drive the electric fan to move. Thus, the stability of the device is improved during the process of the pulley 7 extending, and the use safety is increased. The structure of this device is simple, reducing the complexity and weight of the device, with a low cost and simple operation.

[0038] Working principle: During the working process of the present utility model, when it is necessary to move the electric fan, press or step on the first pressing ring 4 and the second pressing ring 5. Since the second pressing ring 5 is located above the first pressing ring 4, the second pressing ring 5 first moves downward, causing the connecting rod 13 fixedly connected to the second pressing ring 5 to also move downward, thereby driving the sliding block 141 in the installation box 14 to move downward in the sliding groove 142, so that the support plate 144 fixedly connected to the bottom of the sliding block 141 moves downward to contact the ground, thus lifting the base 2, increasing the contact area between the electric fan and the ground, and preventing the electric fan from tipping over. Subsequently, the first pressing ring 4 is squeezed, causing the sliding rod 9 to move downward, making the moving block 8 and the pulley 7 fixedly installed at the bottom of the sliding rod 9 move downward, so that the pulley 7 contacts the ground. Rotate the limiting rod 11 so that one end of the limiting rod 11 rotates above the first pressing ring 4, thereby limiting the first pressing ring 4 and making the pulley 7 extend out of the base 2. Finally, release the first pressing ring 4 and the second pressing ring 5, and the second pressing ring 5 is reset upward under the action of the second spring 143, causing the sliding block 141 and the support plate 144 to move upward, and the support plate 144 leaves the ground, without affecting the pulley 7 to drive the electric fan to move. Thus, the stability of the device is improved during the extension process of the pulley 7, and the use safety is increased. The structure of this device is simple, reducing the complexity and weight of the device, with a low cost and simple operation.

[0039] The above specific embodiments are merely several alternative embodiments of the present utility model. Based on the technical solution of the present utility model and the relevant revelations of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
