Description

(Fan Can Be Connected With Portable Terminal)

The present invention relates to a small-sized fan, and more particularly, to a small-sized fan that is connected to a power terminal provided in a portable terminal such as a mobile phone, a smart phone, and a tablet PC, The present invention relates to a small fan.

On a hot summer day, a small fan can help you with the heat. Especially for a woman who wears makeup, if she sweats a lot on her face due to heat, she may suffer difficulties due to makeup.

Such a problem has been proposed to cool down the heat immediately. There have been many miniature fans that can be carried in a pocket. A typical miniature fan has a motor, so batteries must be fitted without exception. When a battery is to be installed, the volume and weight of a small fan are inevitably increased. If the battery power is exhausted during use, it becomes useless. Because of this problem, a self-rotating or self-generating small fan has been proposed, but it is not widely used because it is inconvenient to use.

The present invention provides a fan for a portable terminal.

According to an aspect of the present invention, the first casing is cylindrical, the second casing is a rectangular box, and the hinge connection portion may be capable of adjusting the connection angle of the first and second casings in a stepwise manner .

According to another feature of the present invention, the first casing is supported on the ground so that the first casing can be supported without being shaken while being inclined at a predetermined angle with respect to the ground, and the other end is hinged to the side wall of the first casing .

According to another aspect of the present invention, the blowing fan includes a hub coupled to an output shaft of the motor and rotating about an X axis, and a plurality of blades radially connected to the hub; The blade is characterized by being made of a thin flexible synthetic resin material that can be folded.

According to the above configuration, a small-size fan can be provided that can be connected to a terminal of a portable terminal having the highest frequency of use in recent years, and can be powered from the portable terminal. According to a more specific feature of the present invention, the fan direction of the fan can be adjusted according to the user's need, thereby providing a fan for a portable terminal with improved ease of use.

1 is a perspective view of a small fan connected to a portable terminal according to an embodiment of the present invention.
FIG. 2 is a use state diagram and a side view of a small-sized fan connected to a portable terminal according to an embodiment of the present invention.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings attached hereto.

A small fan (hereinafter, referred to as 'fan') connected to the portable terminal of the present invention is connected to a power supply terminal of various portable terminals and can receive power from the portable terminal. The mobile terminal basically includes a mobile phone, a smart phone, a tablet PC, a notebook, and an electronic dictionary. However, if it is possible to carry, the electrical connection is possible through the male and female coupling between the terminals, and the electric source is included, all of them should be considered to be within the scope of the present invention. Therefore, it is possible to charge the battery of the portable terminal, and a battery charger or a battery pack for a portable terminal equipped with a terminal can be connected to the fan of the present invention.

The fan includes a first casing 20 in which the motor 10 is incorporated and a second casing 21 connected to the first casing 20 by a hinge connection 30. [ The terminal portion 40 is retracted into the second casing 21. The terminal unit 40 may be electrically connected to a power connection terminal provided in a portable terminal P such as a cellular phone, a smart phone or a tablet and is electrically connected to the motor 10 built in the first casing 20. Finally, the blowing fan 11 is connected to the output shaft of the motor 10 and winds forward as it rotates.

According to the feature of the present invention, the first housing 20 is cylindrical, and the second housing 21 is a square cylinder.

2, the hinge connection portion 30 can change the connection angle of the first and second housings 20 and 21 while rotating around the Y axis in FIG. The hinge connection portion 30 may be a hinge connection structure widely used throughout the industry. For example, there is a hinge connection structure in various places such as a desk lighting stand for easy angle adjustment, a rod-shaped support device (aka, self-supporting rod) for self-photographing of a mobile phone, and a room mirror control unit .

The hinge connection portion 30 is formed by a disk-shaped support frame 31 and 32 integrally formed on both sides of the first casing 20 and a second casing 21 connected to the support frame 31 and 32, And a washer 34 for interlocking between the support shafts 31 and 32 and the rotary shaft 33 for lubrication.

The angle of the first and second casings 20 and 21 may be adjusted stepwise along the direction of the arrow K in FIG. For example, 30 °, 45 °, 60 °, 90 °, 120 °, or the like. A person skilled in the art will be able to construct the hinge connection portion having such a function without difficulty, so that a detailed description thereof will be omitted. In some cases, a locking means for fixing the state adjusted at a predetermined angle may be further provided. The locking means may be a manner of fixing the angle of the first and second housings 20, 21 by turning the butterfly nut type rotation lever as in a desktop lighting stand, for example.

One end of the first housing 20 is supported on the ground so that the first housing 20 can be supported without being shaken while being inclined at a predetermined angle (for example, 45 degrees) with respect to the ground, and the other end is supported on the side wall of the first housing 20 A brace (not shown) that is hinged may be provided. So that the portable terminal P can be stably fixed when ventilating the user's face in a state where the portable terminal P is placed on the floor of a desk or the like.

Although the terminal portion 40 is shown as a USB terminal having four terminal pins 41 as shown in the figure, it is not limited thereto and various terminals to be distributed or to be distributed in the market may be substituted .

The blowing fan 11 is composed of a hub coupled to the output shaft of the motor 10 and rotating about the X axis and a plurality of blades radially connected to the hub. The blade portion can be made of a thin, flexible plastic material that can be folded. In this case, the protective cap (not shown) is inserted into the first casing 20 in the same manner as the lipstick lid, thereby protecting the blade and reducing the volume of the fan. In addition, the terminal portion 40 may be drawn into the second casing 11 by the sliding method as used in the conventional USB. And may further include a cap (not shown) that can cover the terminal portion 40.

The blowing fan 11 can be configured to be replaceable according to the needs of the user. The output shaft of the motor 10 and the blowing fan 11 can be disassembled and assembled in the same manner as a general household fan. According to this, it is possible to replace the blade with a new one when the blade is damaged, or to replace the household items (or toys, etc.) using other types of motors as needed.

The above description is only an example based on the technical idea of the present invention. Those skilled in the art will recognize that various modifications may be made by those skilled in the art without departing from the scope and spirit of the invention as expressed in the claims. For example, all of the above-described embodiments may be freely combined and practiced by those skilled in the art, and any combination thereof should be construed as being included in the scope of the present invention.
