[0043] The fan is a very common household appliance in daily life, which helps to dissipate heat by pushing air flow. The telescopic folding fan is loved by people because of its portability and easy carrying. The telescopic folding fan on the market usually includes a fan body, a telescopic rod and a base. The telescopic rod connects the fan body and the base, and by adjusting the length of the telescopic rod, the telescopic folding fan can be switched between the unfolded and folded states. In the folded state, by rotating the telescopic rod and the base, the telescopic folding fan can be folded up for storage. However, in the folded state, in order to keep the relative position between the telescopic rod and the base fixed, the telescopic rod and the base need to be locked. At present, a buckle, a bolt structure or a sleeve structure is usually used to lock the telescopic rod and the base to prevent the telescopic folding fan from rotating relative to the base during use. When it is necessary to adjust the angle of the telescopic folding fan or to store it, the user must manually unlock the telescopic rod and the base, which makes the storage process of the telescopic folding fan cumbersome and affects the convenience of use of the product.

[0046] In the technical scheme of the embodiment, Figure 1 The telescopic folding fan 100 in the utility model is in the unfolded state, and the fan main body 1 is used to blow heat dissipation to provide cooling effect and help the user to reduce body temperature. Figure 10As shown, the upper sleeve 22 is rotatably connected with the fan body 1, so that the fan body 1 can be flipped with the upper sleeve 22 as the axis. The base 3 comprises an upper cover 31 and a lower cover 32 connected with each other, and the upper cover 31 and the lower cover 32 enclose a receiving cavity 33. The upper cover 31 forms a receiving groove 31a recessed downward from the top end of the upper cover 31. Specifically, the receiving groove 31a is provided with a through opening 31b communicating with the receiving cavity 33, and the gland 4 is arranged in the receiving cavity 33 and corresponds to the through opening 31b, so that the gland 4 can block the through opening 31b. The through opening 31b has a first recessed portion 31c in a semicircular shape, and the gland 4 forms a second recessed portion 4a in a semicircular shape. The second recessed portion 4a and the first recessed portion 31c jointly form a rotating hole 41, and the rotating shaft 231 can extend into the rotating hole 41. By rotating the rotating shaft 231 relative to the rotating hole 41, the lower sleeve 23, the telescopic rod 21 and the upper sleeve 22 are driven to rotate.

During the rotation of the rotating shaft 231 relative to the rotating hole 41, the position of the first clamping block 231a is reasonably arranged, so that when the supporting structure 2 is in the unfolded state, the first clamping block 231a extrudes the first elastic protrusion 4b and is clamped into the clamping opening 4c between the two first elastic protrusions 4b, thereby ensuring the stability of the telescopic folding fan 100 in the unfolded state. When the telescopic rod 21 needs to be in the folded state, the user only needs to rotate the lower sleeve 23, so that the first clamping block 231a extrudes the first elastic protrusion 4b again, so that the first clamping block 231a is released from the clamping opening 4c. Without manually unlocking the telescopic rod 21 and the base 3, the telescopic folding fan 100 is convenient to store, and the use convenience is increased. When the first clamping block 231a is clamped into the clamping opening 4c, the telescopic folding fan 100 is in the unfolded state. The end of the gland 4 facing the lower sleeve 23 is provided with a second elastic protrusion 4d, and the bottom end of the lower sleeve 23 is provided with a second clamping block 23a. During the rotation of the lower sleeve 23, the second clamping block 23a extrudes the second elastic protrusion 4d, and the second elastic protrusion 4d is extruded and deformed. By reasonably arranging the relative positions of the second clamping block 23a and the second elastic protrusion 4d, the second clamping block 23a and the second elastic protrusion 4d extrude each other when the telescopic folding fan 100 is in the unfolded state, so as to increase the stability of the telescopic folding fan 100 in the unfolded state, and prevent the telescopic rod 21 from falling.

The control panel 6 is electrically connected with the driving motor 54 and the battery 8. In the embodiment, the rotating assembly 5 comprises a plurality of rotating wheels 51. The upper cover 31 is provided with the wheel grooves 52. The plurality of rotating wheels 51 are arranged in the wheel grooves 52 one by one. The control panel 6 can be an existing control panel 6 to control the wind direction and the wind power. Specifically, the driving motor 54 can drive the upper cover 31 to rotate relative to the lower cover 32. The annular rack 53 matched with the upper cover 31 can be arranged on the lower cover 32, so that the output shaft of the driving member 14 drives the gear 541 to move along the circumferential direction of the annular rack 53, and drives the upper cover 31 and the base 35 to rotate relative to the lower cover 31. The matching contact surface of the annular rack 53 and the driving motor 54 is on the side of the base 3 lower cover 32 close to the center of the circle, or on the side of the base 3 lower cover 32 away from the center of the circle. The annular rack can also be in other shapes, such as a straight rack. The embodiment of the specification does not limit this, so as to drive the telescopic folding fan 100 in the embodiment to rotate left and right.
