The blower outlet is opened on the side of the blower box, and the blower box is connected to the connecting seat.

[0009] Furthermore, the blower box is a silicone box.

[0010] Furthermore, the support unit includes a telescopic rod and a foot, the telescopic rod being mounted on the housing of the fan body, and the foot being fixed to the telescopic end of the telescopic rod.

[0011] Furthermore, the support unit also includes a vacuum suction cup, which is mounted on the bottom of the foot.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This adjustable portable mini fan has the following advantages:

[0013] 1. The flexible ventilation unit is placed against the user's neck, allowing for close contact with the neck and ensuring a cooling effect, thus improving the user's experience.

[0014] 2. The fan body is supported and fixed by the support unit. The blowing angle of the air outlet on the blower box can be adjusted by rotating the connecting seat. It is easy to support and fix and easy to use. At the same time, it can be used indoors or outdoors. The blowing angle can be adjusted, which makes it flexible and practical.

[0020] The present invention will be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention.

[0021] Please see Figure 1-4 This embodiment provides a technical solution: an adjustable portable fan, including a fan body 1, a support unit 4 installed at the bottom of the fan body 1, a connecting seat 2 rotatably connected to the air outlet of the fan body 1, a flexible ventilation unit 3 fixedly connected to the connecting seat 2, and air inlets 5 evenly opened on the side of the flexible ventilation unit 3.

[0022] It also includes a rotary joint 6, through which the air outlet of the fan body 1 is rotatably connected to the connecting seat 2, ensuring the rationality of the design.

[0023] The flexible ventilation unit 3 includes a gooseneck tube 31 and a blower box 32. Several blower boxes 32 are provided, and adjacent blower boxes 32 are connected by the gooseneck tube 31. The blower port 5 is opened on the side of the blower box 32. The blower box 32 is connected to the connecting seat 2. The blower box 32 is a silicone box to ensure the comfort of contact with the user's skin. The angle between the blower boxes 32 is adjusted by the gooseneck tube 31 so that the blower box 32 can be placed against the user's neck. Then, the fan body 1 blows air into the blower box 32. The blower box 32 blows air to the user through the blower port 5 to cool down. It can be used against the neck to ensure the cooling effect and improve the user's experience.

[0024] The support unit 4 includes a telescopic rod 41 and a foot 42. The telescopic rod 41 is installed on the housing of the fan body 1, and the foot 42 is fixed to the telescopic end of the telescopic rod 41. The support unit 4 also includes a vacuum suction cup 43, which is installed at the bottom of the foot 42. When used indoors, the fan body 1 can be supported by the foot 42. The height of the fan body 1 can be adjusted by telescopically extending the telescopic rod 41. Then, the blowing angle of the blower 5 on the blower box 32 can be adjusted by rotating the connecting seat 2. The foot 42 can be attached to a smooth surface by the vacuum suction cup 43. It is convenient to support and fix, easy to use, and can be used indoors or outdoors. The blowing angle can be adjusted, making it flexible and practical.

[0025] The working principle of the adjustable portable fan provided by this utility model is as follows: The angle between the blower boxes 32 is adjusted by the gooseneck tube 31 so that the blower box 32 can be placed against the user's neck. Then, the fan body 1 blows air into the blower box 32, and the blower box 32 blows air to the user through the air outlet 5 to cool them down. When used indoors, the fan body 1 can be supported by the foot 42, and the height of the fan body 1 can be adjusted by extending and retracting the telescopic rod 41. Then, the blowing angle of the air outlet 5 on the blower box 32 can be adjusted by rotating the connecting seat 2. The foot 42 can be attached to a smooth surface by the vacuum suction cup 43.

[0026] It is worth noting that the components disclosed in the above embodiments are all general standard parts or parts known to those skilled in the art. Their structures and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods. The telescopic rod 41 adopts a new type of telescopic rod, which is a telescopic hollow cylindrical rod made of metal strip or plastic sheet. Its feature is that the metal strip or plastic sheet is pre-shaped into an elastic coiled layer with memory function smaller than the outer diameter of the rod, thereby having a self-tightening function, so that the coiled layer always has elastic potential energy to apply pressure to the telescopic rod.

[0027] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances. For example, a rotary connection can refer to a rotary connection through a bearing.

[0028] The parts of this utility model not described in detail are prior art. Although this utility model has been specifically shown and introduced in conjunction with preferred embodiments, there are many methods and approaches to implement this technical solution. The above description is only a preferred embodiment of this utility model. However, those skilled in the art should understand that various changes in form and detail can be made to this utility model without departing from the spirit and scope of this utility model as defined by the appended claims, and all such changes shall be within the protection scope of this utility model.
