DETAILED DESCRIPTION

[0023] Now, the preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0024] See also Figure 1 , Figure 1 The front view of an embodiment of a fan of the present invention. The present invention provides a fan 10, which includes: a plurality of small fan units 1 and a base 2 that cooperates with these small fan units 1. Among them, these small fan units 1 are installed on the base 2 in an insertable / removable manner. A single small fan unit 1 itself can be regarded as an independent fan. It can be taken off the base 2 and used as a shared electric fan for a single person; and a plurality of small fan units 1 are installed on the base 2, which can be used as a table fan or a floor fan for multiple people.

[0025] The base 2 is tree-shaped, and includes an upright trunk 26 and six docking portions 27 branching from two sides of the trunk 26 . Each docking portion 27 is similar to a branch on the trunk 26 and is used to correspond to a small fan unit 1 .

[0026] On the one hand, the docking portion 27 provides a mechanical connection structure to ensure that the small fan unit 2 is firmly mounted on the base 2. For example, the mechanical connection structure may be a snap connection structure, such as: a snap structure is provided on the small fan unit 1, and a corresponding snap structure is provided on the docking portion 27;

[0027] On the other hand, the docking portion 27 provides an electrical connection structure to ensure that the circuit system in the small fan unit 1 is electrically connected to the circuit system in the base 2. For example, the electrical connection structure can be a USB interface, such as: a USB plug is provided on the small fan unit 1, and a USB socket is provided on the docking portion 27.

[0028] See also Figure 2 , Figure 2 2 is a three-dimensional diagram of an embodiment of the fan of the present invention. A control display unit 21 is provided on the trunk 26 of the base 2, and a second connection port 22 is provided on the docking portion 27 of the base 2. When a small fan unit 1 is plugged into the second connection port 22, all the fans installed on the base 2 can be controlled through the control display unit 21 (see Figure 1, for example: six) small fan units 1 are working, and the fan 10 can be used as a table fan or a floor fan.

[0029] See also Figure 3 , Figure 3 The front view of the small fan unit in the first embodiment of the fan of the present invention. The small fan unit 1 is a handheld fan, including: a head 11, a fan 12 and a bottom 13. The head 11 and the fan 12 are combined together to discharge air. The bottom 13 can be regarded as a handle in terms of mechanical structure for the user to hold.

[0030] See also Figure 4 , Figure 4 The cross-sectional view of the small fan unit in the fan embodiment of the present invention. The bottom 13 is provided with: a button 131, a rechargeable battery 132 and a first connection port 133. The rechargeable battery 132 is arranged inside the bottom 13, and the button 131 is used to control the rotation of the fan 12 by power supplied by the rechargeable battery 132. The first connection port 133 is arranged at the end of the bottom 13. When the small fan unit 1 is used up and inserted back into the base 2, the rechargeable battery 132 in the small fan unit 1 can be charged by means of the corresponding connection between the first connection port 133 and the second connection port 22 on the base 2.

[0031] In this embodiment, the first connection port 133 and the second connection port 22 are wired connected. For example, the first connection port 133 includes a USB plug, and the second connection port 22 includes a USB socket. The USB plug and the USB socket are matched to each other, so that the rechargeable battery 132 can be charged.

[0032] In other embodiments, the first connection port 133 and the second connection port 22 may be wirelessly connected. For example, the first connection port 133 includes a first induction coil, and the second connection port 22 includes a second induction coil, and the second induction coil is matched with the first induction coil to charge the rechargeable battery 132.

[0033] It is understandable that in some embodiments, by means of the corresponding connection between the first connection port 133 and the second connection port 22, only the rechargeable battery 132 in the small fan unit 1 can be charged. The working state of the fan 12 in each small fan unit 1 on the base 2 is individually controlled by the button 131 in this small fan unit 1.

[0034] In other embodiments, by means of the corresponding connection between the first connection port 133 and the second connection port 22, the base 2 can not only charge the rechargeable battery 132 in the small fan unit 1, but also control the working state of the fan 12 in the small fan unit 1.

[0035] For example, see Figure 1 By means of the corresponding connection between the first connection port 133 and the second connection port 22, the control display unit 21 can be manipulated to bypass the operation of the button 131 in the small fan unit 1, so that all six small fan units 1 on the base 2 are in the air supply state, or a part of the six small fan units 1 on the base 2 are in the air supply state.

[0036] The beneficial effect of the present invention lies in that the small fan unit 1 is cleverly coordinated with the base 2, and a fan 12, a rechargeable battery 132 for powering the fan 12, and a first connection port 133 capable of charging the rechargeable battery 132 are provided in the small fan unit 1. With the cooperation of the first connection port 133 and the second connection port 22 on the base 2, the rechargeable battery 132 can be charged, and the combination of several small fan units 1 and the base 2 can be used as a table fan or a floor fan for multiple people, and a single small fan unit can also be used as a shared electric fan for a single person.

[0037] See also Figure 5 , Figure 5 It is a front view of another embodiment of a fan. The present invention proposes a fan 10a, which includes: a plurality of small fan units 1 and a base 2a that cooperates with these small fan units 1. The difference between the base 2a and the base 2 in the aforementioned fan 10 is mainly reflected in: the base 2a includes: an upright trunk 26a and an inner ring type connection structure 28a arranged at the top of the trunk 26a, and the inner ring type connection structure 28a is built with a plurality of connection parts (not shown in the figure), and each connection part (similar to the function of the aforementioned connection part 27) is used to correspond to a small fan unit 1. In other words, the five small fan units 1 are distributed in a circular ring on the base 2a with the help of the inner ring type connection structure 28a, and the heads of the small fan units 1 face outwards.

[0038] See also Figure 6 , Figure 6 It is a front view of another embodiment of the fan. The present invention proposes a fan 10b, which includes: a plurality of small fan units 1 and a base 2b that cooperates with these small fan units 1. The difference between the base 2b and the base 2 in the aforementioned fan 10 is mainly reflected in: the base 2b includes: an upright trunk 26b is arranged on the top of the trunk 26b The outer ring type connection structure 28b, this outer ring type connection structure 28b is built with a plurality of connection parts (not shown in the figure), each connection part (similar to the function of the aforementioned connection part 27) is used to correspond to a small fan unit 1. In other words, the five small fan units 1 are distributed in a circular ring on the base 2b with the help of the outer ring type connection structure 28b, and the heads of the small fan units 1 face inwards.

[0039] It should be understood that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. For those skilled in the art, the technical solutions described in the above embodiments can be modified, or some of the technical features therein can be replaced by equivalents; and these modifications and replacements should all fall within the scope of protection of the claims attached to the present invention.
