Mist spraying device

A mist spraying device comprising:

• a base, an interior of the base is provided with a control circuit and a battery chamber, wherein the control circuit is equipped with control functions of atomizing by oscillation, water level sensor and a condition display;
• the battery chamber is provided with at least a battery to provide the control circuit with required working power by electricity of the battery;
• a side of the base is provided with a switch which is connected with the control circuit and is pressed down to control the control circuit to activate the control function of atomizing by oscillation, a periphery on a top of the base is provided with an illumination device which is controlled by the control circuit to display a condition of spraying the atomized water or liquid, electricity of the battery or water level, and the top of the base is provided with plural metal junctions which are connected with a power end and a sensor end of the control circuit;
• a water tank, the water tank is assembled on the top of the base and a bottom of the water tank is provided with plural conductor junctions, with that the conductor junctions are connected with the metal junctions on the top of the base, an interior of the water tank is provided with a containing sink which holds water or liquid, an interior of the containing sink is provided with a water level sensor to sense water level or liquid level in the containing sink, an exterior of the water tank is provided with an exit which is connected with the containing sink and is assembled with an atomizing plate, wherein the atomizing plate atomizes and outputs water or liquid in the containing sink;
• the water level sensor and the atomizing plate are connected by wirings with the conductor junctions, so that the water level sensor and the atomizing plate are connected with the metal junctions of the base, thereby enabling the control circuit of the base to control the atomizing plate to operate the atomization of water or liquid by oscillation, and to output a condition of water level or liquid level sensed by the water level sensor to the control circuit;
• and an upper lid, the upper lid is assembled at the top of the base and covers the exterior of the water tank, with that the upper lid is provided with a spraying hole through which atomized water or liquid outputted from the atomizing plate of the water tank is sprayed out.
