[0002] Fans, as an indispensable household appliance in modern life, rely on a motor to drive the fan blades to rotate, thereby accelerating airflow to achieve a cooling effect. Especially in the hot summer, fans have become an important tool for people to escape the heat.

[0003] Currently, existing portable fan designs typically consist of two parts: the fan body and the handle. These two parts are usually connected by a fixed structure. The fan is held by hand to blow air, thus achieving the purpose of cooling and relieving heat. However, the fan body and handle of existing portable fans are connected by a fixed structure and cannot be separated or folded. When carrying the fan, users often need to occupy a lot of space, which is inconvenient for users to carry and store.

[0028] In one embodiment of this utility model, such as Figure 1-3 As shown, a foldable mini fan is provided, including a blowing module 10, an adjustment component 20, and a base 30. The blowing module 10 has fan blades 11 for blowing air. The adjustment component 20 is rotatably mounted on the blowing module 10 and is used for height adjustment of the blowing module 10. The base 30 is rotatably mounted at the bottom of the adjustment component, and the base 30 has an upward-opening storage slot 31. When the adjustment component is folded, the side end of the adjustment component is folded into the storage slot 31.

[0029] By setting the adjustment component 20, the blower module 10 and the base 30 can be flexibly folded and stored, reducing the size of the fan when not in use and improving portability. At the same time, by setting the storage slot 31 on the base 30, the folded adjustment component 20 can be stored, making the entire fan more neat and orderly when stored, avoiding the storage problems caused by the fixed structure of traditional fans.

[0030] Preferably, the adjustment assembly 20 includes a movable rod 21 and a telescopic rod 22. The bottom end of the telescopic rod 22 is rotatably mounted on the base 30. The top end of the telescopic rod 22 has a corresponding movable cavity 211. The bottom end of the telescopic rod 22 is slidably connected to the movable cavity 211, and the top end of the telescopic rod 22 is rotatably connected to the blower module 10. By setting the movable rod 21 and the telescopic rod 22, the height of the fan can be flexibly adjusted while maintaining the compactness of the structure, making the fan more flexible and convenient to carry and store.

[0031] Furthermore, both sides of the telescopic rod 22 are provided with outwardly protruding guide portions 221. A guide rail corresponding to the guide portion 221 is provided on the inner side of the movable cavity 211. The guide portion 221 is slidably connected to the guide rail. By providing the guide portion 221 and the guide rail, the sliding of the movable rod 21 within the connecting rod is guided, allowing the movable rod 21 to move smoothly and improving its stable movement.

[0032] Furthermore, a first locking element 23, which is a bolt, is provided on one side of the movable rod 21. One end of the first locking element 23 is threaded to one side of the movable rod 21, and the other end passes through one side of the movable rod 21 and is tightly connected to the outside of the guide portion 221. By providing the first locking element 23, the first locking element 23 ensures the stability of the adjustment assembly 20 after it is adjusted to the correct position, prevents loosening due to accidental contact or vibration, and maintains the stability of the fan structure.

[0033] Furthermore, the bottom end of the first locking member 23 is provided with a first elastic part 231, which is made of elastic material. The first elastic part 231 is tightly connected to the guide part 221, and the guide part 221 is provided with a limiting groove 222 for abutting the first elastic part 231. By setting the first elastic part 231 and the limiting groove 222, when the position of the movable rod 21 is fixed, tightening the first locking member 23 causes the first elastic part 231 to engage in the limiting groove 222. Through the elastic deformation of the first elastic part 231, it is tightly connected to the limiting groove 222, further ensuring the stability of the movable rod 21 after it is adjusted to the correct position, preventing loosening due to accidental contact or vibration, and maintaining the stability of the fan structure.

[0034] Furthermore, a damping shaft 12 is provided between the telescopic rod 22 and the fan module. One end of the damping shaft 12 is fixed inside the fan module, and the other end is fixed inside the telescopic rod 22. By setting the damping shaft 12, the blower module 10 can be angled according to the user's needs, and under the action of the damping shaft 12, the blower module 10 can be stably fixed at the adjusted angle, improving the ease of use of the fan.

[0035] Furthermore, a first pivot 32 is provided between the base 30 and the adjusting assembly 20. A second locking member 33, which is a bolt, is provided on one side of the base 30. One end of the second locking member 33 is threaded to one side of the base 30, and the other end passes through one side of the base 30 and is tightly connected to the telescopic rod 22. A second elastic part 331, which is made of elastic material, is provided between the telescopic rod 22 and the second locking member 33. When the base 30 is fixed, by tightening the second locking member 33, the second elastic part 331 is engaged with the bottom side of the adjusting assembly 20. Through the elastic deformation of the second elastic part 331, it is tightly connected to the bottom side of the adjusting assembly 20, ensuring the stability of the base 30 and the adjusting assembly 20 after adjustment.

[0036] Preferably, the blower module 10 includes a protective sleeve 13 and a blower drive component 14. The protective sleeve 13 is rotatably connected to the adjustment assembly 20 via a second rotating shaft. A locking bolt 15 for rotational adjustment is provided between the protective sleeve 13 and the adjustment assembly. The blower drive component 14 is disposed inside the protective sleeve 13, and the blower drive component 14 is a motor, with the fan blade 11 fixedly connected to the output end of the blower drive component 14. When the blower drive component 14 is started, the fan blade 11 is driven to rotate, thereby realizing the blowing of air by the fan.

[0037] Preferably, it also includes a mounting base 24. The mounting base 24 is located outside the adjustment assembly 20. A battery module for power supply is provided inside the mounting base 24. A control button 25 for starting or stopping the blower module 10 is provided on the side of the adjustment assembly 20 away from the mounting base 24. By providing the control button 25, the user can easily turn the blower module 10 on or off, improving the ease of use of the fan.
