In one embodiment, the spray cover 130 can control the amount of spray by controlling the amount of opening and closing of the spray hole 134 based on the humidity measured through the humidity sensor 138. More specifically, the spray cover 130 electrically opens and closes the spray hole cover, which is connected to each of the spray holes 134, based on which of the plurality of preset reference humidity value areas the sensed current humidity value corresponds to It is possible to control the number of the spray holes 134 opened to the outside or the opening and closing degree of each of the spray holes 134, thereby adjusting the spray amount to be sprayed to the outside. For example, when the current humidity measured through the humidity sensor 138 is in the first reference humidity value range, the spray cover 130 may be configured to open all of the spray hole covers of the spray holes 134, In the second reference humidity value area, it is opened 1/4, in the third reference humidity value area is opened 2/4, in the fourth reference humidity value area 3/4 is opened .

In one embodiment, the spray cover 130 may further include a cover electrode terminal (not shown) formed to correspond to the shape of the electrode terminal 118 in the rim of the lower end of the spray cover 130, To the electrode terminal 118 through the electrode terminal 118.

In another embodiment, the control module 150 may be disposed at the bottom of the spray cover 130. [

The control module 150 may control the operation state of the ultrasonic vibrator 128 and the propeller 132 based on the amount of the wireless power supplied to the power module 122. [ The control module 150 controls the wireless power supply control element 140 to control the ultrasonic transducer 128 and the propeller 132 if the amount of the wireless power supplied to the power module 122 is less than the reference power amount Power can be supplied in a divided manner or alternately supplied in a crossover manner so that it is possible to cope with a power shortage situation that can occur in the wireless power receiving process.

The control module 150 controls the wireless power supply control element 140 to control both the propeller 132 and the ultrasonic transducer 128 if the power generated from the power module 122 is greater than the first power reference And can provide the generated power. More specifically, the control module 150 controls the wireless power supply control element 140 when the wireless power over the first power reference is continuously supplied to the power module 122 through the wireless power pad 110 for a predetermined time or more It is possible to supply electric power to the ultrasonic transducer 128 and the propeller 132 and to control each of the ultrasonic transducer 128 and the propeller 132 to operate each operation.

For example, the control module 150 supplies power to the ultrasonic vibrator 128 for a first reference time of 0.1 second when the wireless power of the second power reference of less than 7W is generated from the power module 122, After the power supply to the propeller 132 is stopped, the propeller 132 and the ultrasonic transducer 132 are driven in such a manner that electric power is supplied to the propeller 132 and power supply to the ultrasonic transducer 128 is interrupted for a second reference time of 0.2 second. It is possible to control the power supplied to the power supply unit 128. At this time, the propeller 132 can operate with inertia rotation for 0.1 second, and power rotation for the next 0.2 second.

Assumes a situation where the power module 112 receives less than the first power reference of the wireless power.

In one embodiment, if the power generated from the power module 122 meets a first specific criterion and then the ultrasonic transducer 128 and the propeller 132 are operated, then the control module 150, The power supply to the ultrasonic transducer 128 and the propeller 132 can be cut off. The control module 150 interrupts power supply to the ultrasonic transducer 128 and the propeller 132 when the power below the second power reference is continuously generated from the power module 122 over a certain period of time And can interrupt the power supply to the ultrasonic transducer 128 and the propeller 132 when, for example, the wireless power of less than 5 W is continuously received for 2 seconds or more.

In one embodiment, the wireless power humidifier 100 includes a housing 120 in which a power module 122 is disposed at a lower position in a cleaning process by a user, a semi-through hole 126 in which an ultrasonic vibrator 128 is disposed below, And the spray cover 130, as shown in Fig.

In one embodiment, the wireless power humidifier 100 may further include a water level sensor (not shown) disposed within the housing 120 to measure the level of water within the semi-through hole 126 , When the water level of the water becomes less than a predetermined reference water level value through the control module 150, it is possible to output a notification content indicating that the water inside the semi-through hole 126 is insufficient through the internal speaker or the display module have. In one embodiment, the water level sensor can be implemented as a non-contact infrared sensor that detects infrared rays having a wavelength in a specific range of intervals, and is disposed on one surface of the housing 120, The water level can be measured by sensing the infrared energy emitted by the water. In another embodiment, the water level sensor may be implemented as a contact type infrared ray sensor and may be disposed on the surface of the semi-through hole 126 to measure the water level through contact with water.

In the above embodiment, the control module 150 can control the operation of the propeller 132 and the ultrasonic transducer 128 based on the water level measured by the water level sensor. For example, the control module 150 may control the propeller 132 to reduce the rotational speed to a predetermined reference speed if the measured water level is below a predetermined reference water level value, and the ultrasonic vibrator 128 So that the ultrasonic energy applied to the water can be reduced to the reference energy value.

In FIG. 2, the power module 122 may receive wireless power from the wireless power pad 110 (step S210).

The ultrasonic transducer 128 may be operated (step S230) if the wireless power received from the power module 122 meets a first specific criterion before operation (step S220). When the ultrasonic transducer 128 is powered by the power module 122, the ultrasonic transducer 128 applies ultrasonic energy to the water in the semi-through hole 116 to supply steam generated in the semi-through hole 116 to the spray hole 134). &Lt; / RTI &gt; In this process, the propeller 132 can rotate the wing to induce the air flow inside the semi-through hole 116, thereby spraying the water vapor inside the semi-through hole 116 to the outside.

If the second specific criterion is satisfied after the operation (step S240), the ultrasonic transducer 128 can be stopped.

The wireless power humidifier 100 may perform the humidification by supplying the wireless power received from the wireless power pad 110 via the power module 122 to the ultrasonic transducer 128 and the propeller 132 through the above steps .

In one embodiment, the wireless power humidifier 100 is configured to be spaced apart and separable between a semi-through hole 126 capable of storing water and a power module 122 supplying power to the semi-through hole 126 Thereby facilitating internal cleaning.

In one embodiment, the wireless power humidifier 100 may perform humidification through a fully waterproof ultrasonic transducer 128 to reduce risk factors in the internal cleaning process by the user.

In one embodiment, the wireless power humidifier 100 may place a propeller 132 using a waterproof motor on top of the spray cover 130 to block the risk of electric shock and short circuit.
