[0011] In order to make the purpose, technical solution and advantages of the present application more clear, the embodiments of the present application will be described in detail below with reference to the accompanying drawings. It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other arbitrarily without conflict.

[0012] like Figure 1-4The figure shows different embodiments of a portable fan of the present application. The portable fan of the present application can have a flush base so that it can be placed on any platform for use; a rotating clamp assembly can also be provided at the bottom so that it can be clamped on any crossbar for use, and the rotating clamp assembly can be rotated to any specified position, and the use environment can be, for example, an umbrella, a vehicle or a baby carriage; a pitch assembly is provided on the top of the portable fan so that it can be pitched up and down to blow air.

[0013] like Figure 5 As shown, a portable fan of the present application includes a head assembly, a column assembly and a rotating clamp assembly. The head assembly is connected to the top of the column assembly through a rotating rod assembly, and the bottom of the column assembly is connected to the rotating clamp assembly. The rotating clamp assembly can be directly installed on a fixed part of an object, such as an umbrella, a vehicle or a baby carriage; the rotating clamp assembly can also be connected to a base assembly, and then placed on a platform, such as a desktop or an operating surface, through the base assembly.

[0014] The mesh cover assembly includes a front mesh cover 10 and a rear mesh cover 11. The mesh cover space enclosed by the front mesh cover 10 and the rear mesh cover 11 contains a fan blade assembly 12. The front part of the front mesh cover 10 may also be provided with a mesh cover decoration 13. The rear part of the rear mesh cover 11 is provided with a head rear cover 18. A head rotating rod and a head pressing plate 17 are provided between the head rear cover 18 and the rear mesh cover 11. The head rotating rod is installed on the rear mesh cover 11 through the head pressing plate 17. Preferably, the main body of the head rotating rod is L-shaped, formed by the buckling of the head rotating rod upper cover 14 and the head rotating rod lower cover 16. The head rotating rod is provided with a pitch axis, and a silicone sleeve 15 is provided at the pitch axis. The pitch axis is installed on the mounting part of the rear mesh cover 11. The silicone sleeve 15 and the mounting part rely on the static friction of the silicone material to keep the pitch axis at the required pitch position. The silicone sleeve 15 plays a role in preventing the wear of the pitch joint part on the one hand, and on the other hand, it plays a role in enhancing the frictional bonding force of the pitch part.

[0015] The column assembly includes a front shell 20 and a rear shell 21, and the front shell 20 and the rear shell 21 surround the main body of the column assembly. A connecting portion 22 is provided at the top of the column assembly, and a mounting portion 19 is provided at the bottom of the L-shaped main body of the head rotating rod, and the mounting portion 19 is fixedly mounted on the connecting portion 22 through a top cover 23. The bottom end of the column assembly is connected to the rotating clamp assembly through a pressing plate 24. More specifically, the mesh cover assembly can be placed on the rear shell 21, and the rear shell 21 fixes the mesh cover assembly through a buckle to form the main body of the column assembly, and the top cover 23 is fixed to the front shell 20 and the rear shell 21 through a buckle.

[0016] The rotating clamp assembly includes a rotating shaft 34 and a rotating clamp body 30. The rotating shaft 34 is set on the rotating clamp body 30 by screws. The right clamp 38 and the left clamp 39 are fixed on the rotating clamp body 30 by pins 35. The right clamp 38 includes a right shaft pin 37, on which a right torsion spring 32 is provided; the left clamp 39 includes a left shaft pin 36, on which a left torsion spring 33 is provided. A silicone plug 31 is also provided between the right clamp 38 and the left clamp 39, and the silicone plug 31 is provided at both ends of the rotating shaft 34. During installation, the rotating shaft can be first fixed to the rotating clamp by screws, and then the right torsion spring can be installed into the right shaft pin and then installed into the right clamp together, and then the silicone plug can be installed, and they can be fixed together by screws; similarly, the left torsion spring can be installed into the left shaft pin and then installed into the left clamp together, and then the silicone plug can be installed, and they can be fixed together by screws; finally, the left and right clamps can be fixed to the rotating clamp by pins. The rotating shaft 34 of the rotating clamp assembly is sleeved with silicone sleeves 31 at both ends and fixed to the rear housing 21 by screws through the pressing plate 24, so that the rotating shaft can rotate and achieve positioning at different rotating positions by relying on the static friction of the silicone sleeve. In this case, the rotating clamp assembly can be directly installed on an umbrella, a vehicle or a baby carriage to achieve more applications of the portable fan.

[0017] When the base assembly is installed at the bottom of the rotating clamp assembly, the base assembly includes a base 41 and a base cover 42, and the base cover 42 is fixed to the base 41 with a buckle. When the bottom of the rotating clamp assembly is directly installed on the fixed part of the object, the clamping function can be achieved by setting the shapes of the right clamp 38 and the left clamp 39. At this time, the clamp design scheme in the prior art can be adopted, which will not be repeated. In an alternative embodiment, the upper and lower rotating rod pitch mechanism can also be replaced with a metal positioning hose to achieve rotation at any angle; the rotating clamp can also be disassembled for use and fixed by an adapter.

[0018] A portable fan provided in the present application overcomes the shortcomings of traditional handheld fans that they cannot free hands and blow air at multiple angles by changing the product structure, thereby achieving the needs of freeing hands, using in multiple scenarios, effectively improving product usage rate and improving practicality.

[0019] Although the implementation methods disclosed in this application are as above, the contents described are only implementation methods adopted for facilitating the understanding of this application, and are not intended to limit this application. Any technician in the technical field to which this application belongs can make any modifications and changes in the form and details of implementation without departing from the spirit and scope disclosed in this application, but the scope of patent protection of this application shall still be based on the scope defined in the attached claims.
