Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. The terms used are terms selected in consideration of the functions in the embodiments, and the meaning of the terms may vary depending on the user, the intention or the precedent of the operator, and the like. Therefore, the meaning of the terms used in the following embodiments is defined according to the definition when specifically defined in this specification, and unless otherwise defined, it should be interpreted in a sense generally recognized by those skilled in the art.

1 is a configuration diagram of a neck band type portable fan according to an embodiment of the present invention.

Referring to FIG. 1, a neck-band portable air blowing apparatus 100 according to an embodiment of the present invention includes a body 110, a blower 120, and a controller 130.

The body portion 110 is formed of a synthetic resin material. The body portion 110 is formed in the form of a band to be worn on the user's neck. For example, it is preferable that the body 110 is formed to be bent in a 'U' shape, and is formed to have an elastic force so as to be fixed on the neck. A power supply unit (not shown) is formed inside the body 110 to charge the power source. The body portion 110 may be formed to be folded by hinge coupling. At one or more sides of the body portion 110, at least one blow-in portion 120 described later may be formed.

A through hole 111 may be formed at one side of the body 110. The through hole 111 serves to discharge the air introduced through the inside of the body 110. For example, when the air moves into the body 110 through the airflow 120, air is exhausted to the air hole 111. In this case, it is preferable that a passage through which the air moves is formed inside the body 110. The through-holes 111 may be formed in the body around the neck. In addition, the body portion 110 is formed in the shape of an airfoil such that the cross section of the U-shaped bent portion is applied to the Bernoulli principle. In this case, air may be discharged through a narrow gap of the cross section of the body portion 110 to generate a pressure difference.

The airflow 120 is pivotally connected to the body 110 to blow air. The blowing part 120 may be formed at both ends of the body part 110. The blowing part 120 is coupled with the body part 110 by a ball bearing so that the user can change the angle in the direction corresponding to his / her own. The blowing unit 120 sucks outside air through an air inlet 121 using a fan (not shown) and a motor (not shown) and discharges the air to the air outlet 122. The airflow 120 is variable in air volume and wind speed according to the rotation speed of the motor. The blowing unit 120 may filter a fine dust by forming a filter (not shown) on the suction port 121 or the exhaust port 122.

FIG. 2 is an exemplary view for explaining a modified embodiment of the blowing unit of the neck band type portable fan apparatus according to FIG. 1, and FIG. 3 is a view for explaining a connection relation between the portable fan apparatus and the blowing unit according to FIG. Fig.

2 and 3, the blowing part 120 may be formed to have a structure capable of rotating at both ends of the body part 110 at various angles. A paper or film type perfume patch 194 is formed in the air exhaust port of the air supply part 120 so that the air is sprayed so as to provide a perfume to the user. The blowing part 120 may be connected to the body part 110 through a wire 123-1 as shown in FIG. 3 (a). The connection part 123 is connected to the body part 110 and a magnetic body is formed therein to facilitate coupling. The user can freely use the airflow 120 without constraining the body 110 as the wire 123-1 is drawn out from the body 110. [

The airflow 120 may be connected to the body 110 in a wireless manner as shown in FIG. 3 (b). In this case, the blowing unit 120 can recognize whether or not the blowing unit 120 is coupled to the body 110 through the connection unit 124. For example, when the connection part 124 is detached from the body part 110, the power supply part 120 is driven by an internal power supply (not shown). Accordingly, the user can freely use the airflow portion 120 regardless of the position and angle of the body portion 110.

Referring again to FIG. 1, the control unit 130 controls driving conditions including at least one of a driving intensity, a driving direction, and a driving time of the power supply unit 120. The control unit 130 may control the driving intensity, the driving direction, and the driving time of the power supply unit 120 according to the operation of the switch 131 of the user. The control unit 130 may control the driving strength, the driving direction, and the driving time of each of the power supply units 120 when the power supply unit 120 is divided into two or more units.

Also, the control unit 130 may acquire information on the remaining amount of the power source unit, and may control the charging and discharging of the battery. For example, when a plurality of power supply units 120 are formed, the controller 130 may control the operation timing by a pulse width modulation (PWM) method. For example, when the sum of the driving powers for each of the plurality of power sources 130 is within a predetermined period of time in which the one power source 120 and the other power source 130 operate simultaneously, As shown in Fig. This is to keep the timing when the driving power exceeds the maximum allowable power divided by the maximum power in a case where the plurality of the blowing units 130 operate simultaneously.

Meanwhile, the neck-band portable fan apparatus 100 according to the embodiment of the present invention may further include a heat transfer unit 140. The heat conductive part 140 is formed on one side of the body part 110 to contact the skin around the user's neck. The heat transfer portion 140 can be implemented to be heat dissipated or absorbed by electricity. For example, the heat transfer portion 140 may implement a heat dissipation and a heat absorption function by a current flow by a Peltier effect. In addition, the heat transfer portion 140 may be made of a PTC (positive-integer coefficient) material so that heat is not generated at a predetermined temperature or more.

In this case, the control unit 130 may selectively drive the blowing unit 120 and the heat transfer unit 140 according to a predetermined temperature or humidity condition. For example, when the ambient temperature is higher than the predetermined value, the control unit 130 can blow air only to the blowing unit 120, or can drive the heat transfer unit 140 to heat the blowing unit 120 without driving the blowing unit 120 . If the ambient temperature is lower than the preset value, the control unit 130 may drive the heat transfer unit 140 to heat the air without blowing air through the airflow unit 120. This is to selectively drive the blowing unit 120 and the heat transfer unit 140 according to the temperature. The control unit 130 may simultaneously drive the blowing unit 120 and the heat transfer unit 140. [ The control unit 130 may selectively control the power supply unit 120 and the heat transfer unit 140 according to the charging capacity of the power supply unit.

In addition, the neck-band portable fan apparatus 100 according to the embodiment of the present invention may further include a movement information acquisition unit 150. The movement information obtaining unit 150 obtains movement information including at least one of a speed, an acceleration, and a slope at which the body 110 moves. The movement information acquisition unit 150 may be implemented as a sensor for sensing the movement of the body 110. The movement information acquiring unit 150 can grasp the type of movement such as walking, bicycle, and vehicle using the speed and acceleration information while the user wears the neck-band portable air blowing apparatus 100. In this case, the movement information acquisition unit 150 can also use the GPS (Global Positioning System) to further determine the movement type by using the position information. For example, if the body 110 is located on the road, it can be determined that the vehicle is moving. If the body 110 is located in the car, it can be determined that the vehicle is moving on a bicycle or on foot.

In this case, the control unit 130 variably controls the driving condition of the blowing unit 120 according to the movement information. For example, when the moving speed of the body 110 exceeds a preset speed, the control unit 130 may reduce or stop the driving strength of the blowing unit 120. This is because when the body 110 moves beyond a predetermined speed, the user is sufficiently exposed to the wind, so that the need to inject air through the airflow 120 is reduced.

In addition, the controller 130 may determine that the body 110 is in a sleep state when the body 110 deviates from a preset deviation or does not have a motion deviation for a predetermined time, and can variably control the airflow 120. For example, when the user determines that the user is sleeping while driving or studying, the control unit 130 may control the airflow rate or the wind speed to deviate from the sleeping state by varying the airflow 120. In this case, the control unit 130 can also output a warning signal through the alarm unit 170. The alarm unit 170 may display a character warning signal through the display 171 or may output an alarm signal of a sound type through the speaker 172. In this case, the speaker 172 may be formed in the form of an earphone, and may be connected to the body 110 through a rolling wire to be drawn in or drawn out.

In addition, the neck-band portable fan apparatus 100 according to the embodiment of the present invention may further include a biometric information acquiring unit 160. The biometric information obtaining unit 160 obtains the skin temperature, humidity, The amount of secretion of sweat, and the pulse rate. The biometric information is information for grasping the user's body condition. For example, it is possible to analyze the amount of perspiration and the component of perspiration in the biometric information to grasp the health state. The biometric information obtaining unit 160 obtains biometric information at a predetermined time period and generates a rate of change of the biometric information.

In this case, the control unit 130 may output an alarm signal through the alarm unit 170 when the amount of water is less than a predetermined moisture amount according to the biometric information. The control unit 130 may output an alarm signal for the water replenishment through the alarm unit 170 in order to prevent the risk to the health of the user when the rate of change of the biometric information or the accumulation amount exceeds the preset value.

In addition, the control unit 130 can variably control the operation of the airflow 120 or the heat transfer unit 140 according to the biometric information. The control unit 130 can variably control or stop the operation of the power supply unit 120 or the heat transfer unit 140 when the rate of change of the biometric information is out of the predetermined value. For example, when the user exercises while wearing the neck-band portable air blowing apparatus 100, the temperature increases and the amount of sweat increases, thereby increasing the humidity. In this case, the controller 130 may increase the air flow rate and wind speed of the blower 120, or may operate the heat transfer unit 140 in the heat absorbing mode.

In addition, the neck-band portable fan apparatus 100 according to the embodiment of the present invention may further include a communication unit 180. For example, the communication unit 180 can communicate with an external user terminal using 3G, 4G, 5G, WiFi, WiBro, and Bluetooth. The communication unit 180 may receive a control signal for a driving condition including at least one of a driving strength, a driving direction, and a driving time of the power supply unit 120 through an external user terminal.

In addition, the communication unit 180 communicates with an external user terminal to acquire schedule information. The schedule information is schedule information set by the user. The communication unit 180 may output the alarm signal in accordance with the schedule information of the user.

In addition, the communication unit 180 may make a call via a microphone (not shown) in addition to the speaker 172. [ In addition, the speaker 172 may be formed of an earphone of bone conduction type to enable bone conduction communication.

Fig. 4 is an exemplary view for explaining that the neck band type portable fan according to Fig. 1 further includes a communication unit. Fig.

Referring to FIG. 4, the communication unit 180 may record a user's voice and transmit the voice to the user terminal 10. The user terminal 10 can determine the temperature information that the current user feels by data mining the voice information of the user. For example, if the user says " it is really hot today ", it can be transmitted to the neck-band portable fan apparatus 100 to control the temperature to be lowered. In addition, the communication unit 180 may receive the temperature information in which the user has collected the conversation related to the weather by data mining the conversation in the user's SNS account from the user terminal 10. [

In this case, the control unit 130 can variably control the driving conditions of the power supply unit 120 or the heat transfer unit 140 according to the schedule information. For example, the controller 130 obtains information on indoor and outdoor activities in the schedule information, and divides the indoor and outdoor activities of the indoor and outdoor activities, can do. In addition, the control unit 130 can obtain information about the motion in the schedule information and variably control the driving conditions of the power supply unit 120 or the heat transfer unit 140. [ The control unit 130 may vary the driving conditions of the power supply unit 120 or the heat transfer unit 140 based on the temperature information transmitted from the user terminal 10. [ The temperature information provided from the user terminal 10 is a state with respect to the temperature that the user currently feels, and the controller 130 can increase the temperature or decrease the temperature by reflecting the temperature.

Fig. 5 is an exemplary view for explaining that the neck band type portable fan according to Fig. 1 further includes a jetting part. Fig.

Referring to FIG. 5, the neck-band portable fan apparatus 100 according to the embodiment of the present invention may further include a jetting section 190.

The jetting section 190 injects the liquid jetting liquid onto the user's skin. The jetting section 190 may be integrally formed with the neck-band portable fan apparatus 100, or may be detachably attached. For example, the jetting section 190 injects the jetting liquid through the nozzle 191 and is connected to the neckband-type portable fan apparatus 100 through the connector 192. The jetting unit 190 may include an ultraviolet sensor 193 to sense an ultraviolet ray index. Here, the jetting liquid is used to mean all jetting liquids that replenish water, block ultraviolet rays, contain a perfume, or contain deodorant components.

In addition, the jetting section 190 is controlled by the neck band-type portable fan apparatus 100. For example, the control unit of the neck-band portable fan apparatus 100 can control the spraying of the spray liquid to the user's skin when the temperature, humidity, and ultraviolet ray index of the user's skin exceed predetermined preset values. Accordingly, water and nutrients can be continuously supplied to the user's skin, and the ultraviolet ray shielding function can be maintained by applying the spray of the ultraviolet ray blocking component. Further, the jetting section 190 may contain aroma oil as a jetting liquid. When the aroma oil is used as the injection liquid, the aroma oil can be sprayed according to the user's biometric information.

The fragrance pad 194, on the other hand, may be a paper or film type pad and may further include deodorant components, including fragrance such as aroma oil. The perfume pad 194 may be formed in a detachable form on the blow-out portion. The perfume pad 194 serves to provide fragrance or deodorant components to the wind blown from the blow-in portion. In this case, the perfume pad 194 may be a consumable that can be replaced after a certain period of time has elapsed. In addition, the perfume pad 194 may be formed in a solid form.

Meanwhile, the neck-band portable fan apparatus 100 according to the embodiment of the present invention may further include an illumination unit (not shown).
