Description

Necklace-type fan equipped with pest control {NECK BAND TYPE FAN HAVING A FUNCTION OF ERADICATING HARMFUL INSECTS}

In general, a portable fan has a fan head connected to one end of a handle. A portable electric fan realized by replacing or charging a battery is very inconvenient during outdoor activities. There is also a necklace strap connected so that it can be worn around the neck, but due to the weight of the portable fan, it was not possible to wear it around the neck for a long time.

Recently, a necklace-type electric fan has been introduced into the market, which greatly reduces its weight so that it can be worn around the neck at all times and wears a band shape having a fixed semicircular shape around the user's neck. However, conventional necklace-type fans are inconvenient to use when the band worn around the user's neck is firmly fixed and does not fit the user's neck, and is also inconvenient to store due to its bulk.

On the other hand, a device for eradicating mosquitoes and other pests by generating ultrasonic waves using electricity is being used. For example, in Korean Patent Registration No. 10-1471572 (name of invention: portable mosquito repellent), ultrasonic waves can be amplified by resonance to maximize the mosquito repellent area, and emit light that mosquitoes do not like or sterilize. Disclosed is a portable mosquito repellent to which a white LED emitting ultraviolet rays is added.

However, there is a problem in that a user performing outdoor activities on a hot summer day carries both a portable electric fan and an insect repellent, causing great inconvenience to the user.

5 is a block diagram for explaining the main configuration of a necklace-type fan having a pest control function according to the present invention.

Referring to FIG. 5 , the first head 110 includes a first housing 111 and a second housing 112 . The first housing 111 is configured to include a fan (or fan module) and a motor, and a first wind generating unit for generating wind is built-in, and an air inlet (or wind inlet) and an air outlet (or wind outlet) through which air passing through the first wind generator is discharged to the outside of the first housing 111 are formed.

The ultrasonic oscillation element is formed to a certain size so as to be inserted into the second housing 112 of the first header 110, and generates ultrasonic waves for pest control. For example, the ultrasonic oscillation element may be implemented as a circular speaker having a diameter of 15 mm and a width of 2 mm.

The first control unit operates by receiving power from the first battery, controls the transmission of the first battery power to the first wind generating unit, and generates a frequency of a preset signal band when a push signal is input from the pest control operation switch. It outputs to the ultrasonic oscillation element and controls the lighting of the first indicator light.

The first wind generating unit may be implemented by including a motor that generates rotational force according to a wind speed control signal input from the first control unit, and a fan module that is connected to the motor and generates wind by receiving rotational force and rotating. The motor may be implemented as, for example, an OUTER type brushless DC motor (BLDC MOTOR) in which a magnet rotor is disposed outside the stator unit.

The first controller may be implemented as an ultrasonic generator, a motor controller, and an LED controller. The ultrasonic generator unit includes, for example, a frequency modulator having a transistor (Q) for switching and a capacitor (C) for repeating charging and discharging, a frequency output unit for transmitting the frequency modulated by the frequency modulator to the ultrasonic oscillation element, When the pest control operation switch is turned on, it may be configured to include a frequency generator that generates a predetermined frequency and transmits it to the modulator. The function of the ultrasonic generator may be implemented by being included in a CPU that controls the operation of each element according to a pre-stored program.

The ultrasonic generator may be embodied to generate a frequency of a specific band disliked by different pests and output the frequency to the ultrasonic oscillation device according to the operation of the pest control operation switch. In general, a frequency of 7Khz to 26Khz is used to combat summer pests such as mosquitoes, a frequency of 7Khz to 14Khz is mainly used to combat various types of crawling pests other than mosquitoes, and a frequency of 14Khz to 26Khz is used to combat pests such as cockroaches. However, it is known that a frequency of 26Khz∼45Khz is effective to combat small pest species. Therefore, it is preferable that the ultrasonic generator be implemented to generate frequencies of different specific bands according to, for example, the number of pressing manipulations of the pest control operation switch.

The motor control unit controls the motor of the first wind generating unit to control variables such as the rotational speed and torque of the fan module connected to the motor to adjust the inflow and discharge amount of wind. It may be implemented by including an electronic transmission (ESC). The LED control unit displays that ultrasonic waves for expelling pests are being generated when an operation switch signal for expelling pests is input.

The second head 120 includes a third housing 121 and a fourth housing 122 . The third housing 121 of the second header 120 has a second wind generator for generating wind mounted therein, and a plurality of wind generators are installed so that outside air is introduced into the third housing 121 by the second wind generator. An air inlet having long holes having different sizes and shapes and an air outlet having a plurality of long holes adjacent to each other are formed so that air passing through the second wind generator is discharged to the outside of the third housing 121 .

The second wind generating unit may be implemented by including a motor that generates rotational force according to a wind speed control signal input from the second controller, and a fan module that is connected to the motor and generates wind by receiving rotational force and rotating.

The fourth housing 122 of the second header 120 includes a fan operation switch, a second indicator light, a second battery, a charging indicator light, a USB connector, and a second controller.

The second control unit may include a charging control unit, a motor control unit, and an LED control unit. When it is determined that the second battery needs to be charged, the charging control unit outputs a blinking signal with a charging indicator light, and when charging power is input from the USB connector, transfers it to the first battery and the second battery and outputs a lighting signal with a charging indicator light. , When charging of the first battery and the second battery is completed, the charge indicator is controlled to turn off.

The configuration and function of the second motor controller of the second controller are identical to those of the first motor controller of the first controller. However, unlike the first LED control unit, the second LED control unit of the second control unit controls the lighting of the second indicator light to indicate that the first wind generator and the second wind generator are operating when a fan operating switch signal is input. do.

The necklace-type fan equipped with a pest control function according to the above configuration cools the body while preventing the access of pests in a hands-free state, especially when active outdoors in hot weather. In addition, by being implemented to generate ultrasonic waves capable of expelling specific pests with only a simple pressing operation, access of mosquitoes, cockroaches, pests other than mosquitoes, etc. can be prevented. In addition, the shape is deformed by an external force, and after the external force is removed, the fixed necklace portion can be wound around the first and second headers, respectively, and stored, and can be carried in a bag or pocket.

The present invention has been described above based on several examples, which are intended to illustrate the present invention. A person skilled in the art may change or modify the above embodiment into other forms without departing from the spirit of the present invention.
