[0037] In the case of using the floor fan, the fan head 100 is supported by the support rod 200, so that it can be used in a vertical state under the bearing of the base 300. In the case of needing to store the fan, the support rod 200 is removed above the fan head 100 and the base 300, and is disassembled into a plurality of independent sections 201. In this embodiment, the support rod 200 includes two detachable sections 201, which are installed in the mounting position 312 in the mounting cavity 311. In this embodiment, the base 300 is provided with a bottom shell 310 and an upper shell 320 that are connected to each other. Specifically, in this embodiment, the upper shell 320 and the bottom shell 310 are provided with flanges and ring grooves that can be embedded in each other. The flanges can be embedded in the ring grooves to connect the upper shell 320 and the bottom shell 310 and close the mounting cavity 311. At this time, the plurality of sections 201 can be stored in the mounting cavity 311. At this time, the fan head 100 is stacked on the base 300 and is firmly connected to the base 300 by the clamping structure, so that it can form a firm whole. At this time, the fan is stored in a flat structure and can be stored in a relatively small space.

During storage, the floor fan can be easily transported without scattering, which is more convenient for storage and transportation and reduces the space occupied during storage.

[0038] As Figure 2 、 4 shown in FIG. 7, the clamping structure in this embodiment includes a plurality of clamping plates 105 formed on the first outer cover 101 and spaced apart from each other at equal intervals in the circumferential direction, and a clamping groove 106 formed on the clamping plate 105. The clamping structure also includes a clamping block 330 movably provided on the bottom shell 310 and corresponding to the clamping plate 105. The clamping block 330 is movably connected to the bottom shell 310 in the diameter direction of the bottom shell 310. The clamping block 330 includes a main body 331, a clamping hook 332 formed on the main body 331 and corresponding to the clamping groove 106, a pressing end 333 protruding outward from one end of the main body 331 along the circumferential outer wall of the outer shell and constituting a pressing end 333, and an elastic member 334 provided at the other end of the main body 331 and providing an elastic pushing force outward from the outer shell. At the same time, the end face of the bottom shell 310 is also provided with an insertion slot 314 for the clamping plate 105 to pass through and be clamped with the clamping block 330.

[0039] When the fan head 100 is stacked on the base 300, the clamping plates 105 formed on the first cover 101 penetrate into the base 300 along the slot 314, at this time, the main body 331 is moved towards the outside of the base 300 under the elastic pushing of the elastic member 334, so that the clamping hooks 332 are clamped in the clamping grooves 106, thereby firmly clamping the fan head 100 on the base 300. In the embodiment, the clamping plates 105 formed on the cover are provided with two, in other embodiments, in order to improve the reliability of the connection, three or four can also be provided at equal intervals, by arranging the clamping plates 105 at equal intervals, so that the clamping hooks 332 can be clamped with the clamping blocks 330 during the clamping process, the balanced clamping force can be applied to the fan head 100, and the reliability of the connection between the fan head 100 and the base 300 is guaranteed. It can be known that when the pressing end 333 of the clamping block 330 is pressed, the main body 331 is moved towards the inside of the mounting cavity 311 against the elastic pushing force of the elastic member 334, thereby making the clamping hooks 332 and the clamping grooves 106 disengage with each other, and the clamping plates 105 are released from the limitation, so that the fan head 100 can be removed from the base 300.

[0040] In the embodiment, in order to stably connect the clamping block 330 in the mounting cavity 311, a plurality of sliding warehouses 315 respectively accommodating the clamping block 330 are formed in the mounting cavity 311, the clamping block 330 is limitingly and slidingly connected in the sliding warehouse 315, the ribs 335 extending along the diameter direction of the bottom shell 310 are formed on both sides of the main body 331, the limiting tables 3151 corresponding to the ribs 335 and limiting the clamping block 330 from falling out of the sliding warehouse 315 are arranged on the side wall of the sliding warehouse 315, and the ribs 335 and the limiting tables 3151 constitute a sliding pair; one end of the main body 331 corresponding to the pressing end 333 is formed with a rod portion 336, the extension groove 3152 corresponding to the rod portion 336 and accommodating the rod portion 336 therein is formed on the sliding warehouse 315, and the elastic member 334 is sleeved on the rod portion 336. During the movement of the clamping block 330 receiving the elastic pushing force of the elastic member 334, the ribs 335 and the limiting tables 3151 constitute a sliding pair, which can ensure the stable sliding of the clamping block 330 in the sliding warehouse 315, at the same time, the rod portion 336 is accommodated in the extension groove 3152, and the elastic member 334 is sleeved on the rod portion 336, which can limit the distortion of the elastic member 334 during the movement of the clamping block 330, and ensure that the elastic member 334 provides stable elastic pushing force to the clamping block 330.

A direct current power supply unit 108 is fixedly arranged in the mounting space and electrically connected to and drives the driving member 103. The rear cover 107 is correspondingly arranged with the avoiding groove 313, so that after the fan head 100 is stacked on the base 300, the rear cover 107 is accommodated in the avoiding groove 313.

[0046] In the embodiment, the direct current power supply driving unit 108 can be a rechargeable battery, which provides direct current power to the driving member 103 to drive the driving member 103 to rotate, so that the fan blade 104 rotates to blow air. In the embodiment, the driving member 103 is a direct current motor.

[0047] In the embodiment, the control panel 109 is further arranged on the end surface of the second cover 102 away from the first cover 101 and is electrically connected with the direct current power supply and the driving member 103, and the control panel 109 is located at the center position of the first cover 101. In use, the control panel 109 controls the driving member 103 to realize speed control, timing control and the like, and in the embodiment, the control panel 109 comprises a control circuit board and a control switch button, and it can be understood that the control panel 109 in the embodiment can be realized by using the prior art. It is worth noting that in the embodiment, the control panel 109 is arranged at the center position of the second cover 102, which does not affect the air flow when the fan blade 104 rotates, and at the same time, the fan can be conveniently operated. Compared with the structure of arranging the control panel on the support rod 200 or the motor shell, the technical solution is more convenient for operation and more convenient for users to observe the running data of the fan.
