Detailed Description

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be understood that the following description is only exemplary of the present invention and should not be construed as limiting the present invention in any way. The various embodiments may be combined with one another to form other embodiments not described below or explicitly shown in the figures.

Referring to fig. 1 to 3, according to an embodiment of the present invention, a portable fan 10 is provided, including a base 12, a support rod 14 disposed on the base 12, and a fan 16 disposed on the support rod 14, where the fan 16 includes a casing 160 for accommodating fan blades, a motor 18 is disposed at a rear end of the casing 160, a plurality of LED lamp beads 162 (specifically shown in fig. 2) are disposed at a front end of the casing 160, and a transparent lampshade 20 covers the plurality of LED lamp beads 162; a controller (not shown) connected with the rotor of the motor 18 and the plurality of LED lamp beads 162 is arranged in the base 12; the bottom surface 120 of the base 12 is provided with a hook mechanism 22, and the hook mechanism 22 includes a connecting portion 220 rotatably connected to the bottom surface 120 of the base 12 and an at least partially arc-shaped extending portion 222 extending from the connecting portion 220.

Preferably, a top surface 122 of the base 12 opposite the bottom surface 120 is provided with control buttons 124 for controlling a controller in the base 12 to control the operation of the motor 18 in at least one speed range. Preferably, the control buttons 124 further include a button for controlling a controller in the base 12 to control the plurality of LED light beads 162 to be lit/unlit.

It will be appreciated that the at least partially arcuate shape of the extension 222 not only facilitates carrying by a user by gripping, but also facilitates carrying and use by a user by engaging with other structures to allow the portable fan 10 to be hung thereon. For example, the extension 222 may be formed in a hook shape, and when carried by a user, the extension 222 may be hung on a piece of clothing such as the user or a backpack strap, thereby freeing the user's hands; in use, the extension 222 can also be hung on any structure with a recess or protrusion disposed on the wall, such as but not limited to a groove, a nail, etc. disposed on the wall, so that the portable fan 10 of the present invention is not limited to be used in a flat place.

According to one embodiment of the present invention, the controller is a PLC controller, and a rechargeable power supply for supplying power is further disposed in the base 12. Preferably, the rechargeable power source is a lithium battery, and the base 12 is further provided with a USB interface for charging the rechargeable power source.

It should be understood that the specific types of controller/motor/control key/LED lamp beads and the connection means/structures therebetween mentioned above are not intended to limit the present invention, and as mentioned above are merely preferred embodiments of the present invention, the specific types of controller/motor/control key/LED lamp beads and the connection means/structures therebetween may be any suitable type and connection means/structures known to those skilled in the art.

According to one embodiment of the present invention, the connecting portion 220 is spherical, and the bottom surface 120 of the base 12 is provided with a spherical recess 126, and the connecting portion is rotatably received in the spherical recess 126.

An embodiment of the present invention is characterized in that the bottom surface 120 of the base 12 is further provided with a groove 128 matching with the extension 222.

Thus, in the event that it is desired to use (the extension 222 of) the hook mechanism 22 (such as mentioned above), the extension 222 may be rotated out of the slot 128 provided on the bottom surface 120 of the base 12, and since the coupling portion 220 is spherical and rotatably received within the spherical recess 126 provided on the bottom surface 120 of the base 12, the extension 222 may be rotated relative to the bottom surface 120 of the base 12 to any angle desired by the user; and in the case where it is desired to place the portable fan 10 for use, for example, the extension 222 is rotated back into the groove 128 provided on the bottom surface 120 of the base 12, and since the connection portion 220 is received in the spherical recess 126 and the groove 128 is mated with the extension, the bottom surface 120 of the base 12 is flat and the portable fan 10 can be placed in flat position for use after the extension 222 is rotated back into the groove 128.

The size of the slot 128 may be equal to the size of the extension 222. Further advantageously, the slot 128 may be sized larger (preferably, slightly larger) than the extension 222 to facilitate rotation (e.g., manually) of the extension 222 out of the slot 128.

According to one embodiment of the present invention, it is characterized in that a plurality of LED beads 162 are uniformly arranged along the peripheral perimeter of the housing 160. As shown in fig. 2, the circumference of the casing 160 is provided with a circumferential boss structure, the LED lamp beads 162 are uniformly arranged (i.e. at the same intervals) along the surface of the boss, and the transparent lampshade 20 covers the boss structure (fig. 1).

In one embodiment of the present invention, the brightness of the plurality of LED lamp beads 162 is positively correlated with the rotational speed of the rotor of the motor 18. In other words, the greater the speed of the motor 18, the greater the brightness of the LED light bead 162. It can be understood that, a user may use the portable fan 10 in a dark condition, and at this time, the brightness of the LED lamp bead 162 may indicate the rotation speed of the portable fan 10, which is beneficial for the user to adjust the portable fan 10 according to his own needs.

In this embodiment, the user can select any suitable manner to adjust the rotation speed of the portable fan 10, for example, the controller disposed in the base 12 can be connected to the user's mobile phone via bluetooth, so that the user can adjust the rotation speed of the portable fan 10 via the mobile phone according to the instant rotation speed of the portable fan 10 indicated by the LED lamp bead 162 (since the controller is connected to and controls the motor).

In another embodiment of the present invention, the rotation speed of the rotor of the motor 18 may also be positively correlated to the number of light emitting beads in the plurality of LED beads 162. That is, the faster the rotational speed of motor 18, the greater the number of illuminated LED beads. Similarly, the number is also used to indicate the speed of rotation of the portable fan 10. Indicating the rotational speed of the portable fan 10 by the number of the LED beads that emit light facilitates a user to more accurately judge the rotational speed of the portable fan 10 than by the brightness of the LED beads, since the brightness is easily disturbed by external factors such as light.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
