Description

Improved stand type fan {STAND TYPE FAN APPARATUS}

The present invention relates to an improved stand-type fan, and more particularly, by using the fan as a stand type, but by adjusting the height of the fan, the usability as well as the convenience can be greatly improved, as well as the auxiliary battery function of the electronic device can be obtained. It is possible to separate or combine the support leg from the fan as necessary, and it relates to an improved stand-type fan that facilitates packaging and transport as well as usability.

In general, an electric fan is a device that generates wind by electric power and is one of the home appliances that are used a lot in hot summer. It provides cooling wind to users through wind generated by rotating a rotating blade or circulates indoor air and installs it on a wall. It is largely distinguished by a wall-mounted fan that can be used and a stand-type fan that can be mounted and moved on the floor.

Among them, the conventional stand-type fan has a base supported on the same ground as a room floor, an elevating body that is installed to be adjustable in length while being drawn in and out of the support formed to protrude upward from the base, and the upper end of the elevating body. The main body, the motor operably installed inside the main body, the rear safety net fixed by the guard fixing nut while being assembled in accordance with the safety net position pin formed on the front of the main body where the motor is installed, and the rear safety net protruding from the center of the rear safety net. It is composed of an impeller that maintains the state of being assembled by the impeller fixing cap while being inserted into the rotating shaft of the motor, and a front safety net that is assembled while the rear outer end is in contact with the front outer end of the rear safety net that is assembled on the body where the impeller is assembled. .

In addition, a height adjuster for connecting the main body with an impeller and the base in an upright state is provided, and a fixed pipe with a spring internally installed in a structure perpendicular to the center of the pedestal is provided, and then the height adjuster is inserted into the fixed pipe. The resulting elastic action is controlled by the stopper, so that the height of the body with the impeller is adjusted according to the user's convenience.

In such a conventional stand type fan, air is blown while the impeller is rotated by the operation of a motor, and when the stand type fan is placed on the same ground as the room floor and used, there is no problem, but the main body and the floor surface provided with the impeller and the motor As the raised base and the height adjustment device that connects the main body and the base are produced in an integrally connected state, the box size is inevitably increased by the space occupied by the stand-type fan when the produced stand-type fan is packed in a box. As a result, there is a problem in that space utilization is greatly degraded because it occupies a lot of space when transporting as well as storage.

In addition, not only the configuration of the height adjustment device for adjusting the height of the impeller is made complicated, but the spring provided inside the fixed tube is repeatedly contracted and elongated by long-term use, so the function of the stand fan impeller is deteriorated. There is a problem that the height adjustment is not made properly.

Looking at the prior art, a portable fan without wings and a stand-type fan device having the portable fan, which is disclosed in Patent Publication No. 10-2018-0061094, has been devised, which is formed on a handle portion gripped by a user and an upper portion of the handle portion, and the outer peripheral surface A lower casing consisting of an air inlet having a plurality of air inlet holes in it, installed to be connected to the air inlet, and integrally formed at the upper end of the circular tube portion and the circular tube portion in which the fan motor is installed, but formed to expand upward It consists of an upper casing consisting of an expansion pipe that is connected to the upper part of the expansion pipe and has an annular nozzle part formed with a ring-shaped air injection port through which air is discharged and sprayed along the inner circumferential surface. It can be used as a portable type by hanging it on or as a stand type fan while the fan is mounted upright on the mounting unit.

However, in the case of such a conventional fan, since the casing and the mounting unit are separated from each other, the space occupied during packaging, transportation or storage can be reduced to some extent, whereas when used as a stand type, the height of the fan casing is not adjusted. Or there is a problem in that it cannot be used by adjusting the height of the fan according to the use environment.

In addition, there is a problem that the conventional stand type fan only occupies space when not in use because there is no function other than the fan function.

Patent Document 1: Korean Patent Publication No. 10-2018-0061094 (published on June 7, 2018) Patent Document 2: Korean Registered Utility No. 20-0159830 (registered on Aug. 4, 1999)

The present invention makes it possible to adjust the height of the stand-type fan body so as to greatly improve usability as well as convenience, and minimize the space occupied when packaging, storing and transporting the produced stand-type fan, and function as an auxiliary battery. Its purpose is to provide an improved stand-type fan that not only makes it possible, but also makes the overall appearance beautiful by a simple design.

As a means for achieving the above object, the improved stand-type fan of the present invention includes a main body equipped with a motor to which a blowing fan is connected, a blowing fan guard provided on the front side of the main body, and a support leg connected to the main body. In a stand-type fan, a control unit provided on an upper end of the blowing fan guard and electrically connected to a motor provided in the main body, and a blowing strength control unit and a blowing time that are electrically connected to the control unit to adjust the blowing strength of the blowing fan A control unit provided with a blowing time control unit for adjusting the; A first hinge connection part and a second hinge connection part hinged to both sides of the main body, and a handle connecting the first hinge connection part and the second hinge connection part, respectively, so as to be hingedly rotated with respect to the main body, and a connector at the lower end of the main body It is provided, the support leg, and a leg connecting rod that is fitted to the outer surface of the connector or separated from the outer surface of the connector; It consists of a plurality of support legs that are connected to the leg connector to erect and support the main body and adjust the height and the blowing angle of the main body by inclination.

In the present invention, since a main body equipped with a blowing fan and a motor and a support leg supporting the main body against the floor are detachably provided, the blowing angle of the blowing fan can be adjusted by connecting or separating the main body and the support leg.

In addition, since the main body and the supporting leg are separated, the main body and the supporting leg can be separated and used according to the environmental conditions, which greatly improves convenience.

In addition, as the main body and the supporting leg are detachable, space utilization can be improved because it does not take up a large amount of space when packaging or storing or transporting in a box after production.

In addition, after separating the main body and the support leg, the handle of the main body can be rotated to be hung on the ceiling of the tent, so usability can be greatly improved.

In addition, it is possible to charge the power required for electronic devices such as smartphones, notebooks, or tablet PCs, so that a separate rechargeable battery is not required. In addition to the fan function, various functional effects can be obtained together, and the overall appearance can be beautifully produced by a simple design. have.
