The invention provides a piezoelectric two-phase flow ultrasonic atomization spraying nozzle. The piezoelectric two-phase flow ultrasonic atomization spraying nozzle comprises a piezoelectric vibrator, an amplitude-change pole, a second end cover and a first end cover; the piezoelectric vibrator and the amplitude-change pole are connected through a connecting bolt; an air inlet connector is installed at the tail of the connecting bolt; the second end cover is fixed to the front end of the amplitude-change pole; a laval type valve element is fixed into a step hole of the amplitude-change pole and a groove of the second end cover; a liquid inlet hole is formed in the hole wall face of the step hole of the amplitude-change pole; a plurality of flow guide holes are formed in the positions, close to an outlet, of the laval type valve element in the radial direction; the first end cover is threaded connection to the second end cover; a radial positioning ring is arranged at the position of a clamping groove in the back end of the first end cover; a step type taper valve is installed on the radial positioning ring; the step type taper valve and a vibration separating plate are connected through an adjusting bolt; a resonance chamber is formed between the vibration separating plate and the top end of the first end cover; and a plurality of flexible pipes are arranged in the resonance chamber. According to the piezoelectric two-phase flow ultrasonic atomization spraying nozzle, a large number of superfine fog drops are generated under the low-energy working condition, and the shortcoming that large pulverization amount, small grain size, low power dissipation and directed spraying cannot be considered at the same time through in the traditional technology is overcome.

An electric-cigarette undertaking nanometer dimension fineness space heating pulverization to nicotine solution comprises a cigarette pole and a cigarette holder connected with the front end of the cigarette pole. The cigarette pole is a hollow rod shape cigarette pole welded with a plug at the back end. The intracavity of the cigarette pole is provided with a rechargeable battery, a liquid storage tank for storing nicotine solution, an imbibition liquid core arranged at the front end of the liquid storage tank and contacted with the nicotine solution, and a heater of space heating pulverization arranged inside the heating cavity positioned in the front part of the cigarette pole. The wall of the cigarette pole corresponding to the liquid storage tank is provided with a liquid inlet communicated with the liquid storage tank. Any place of the wall of the cigarette pole is provided with an electric heating switch. The center of the cigarette holder is provided with a hollow pipe which extends into the cigarette pole. The wall of front part of the cigarette holder is provided with a piezoelectric press sensor. The back end of the cigarette pole is provided with a recharging connectiondevice which can charge the rechargeable battery through outer power. The piezoelectric press sensor is communicated with the rechargeable battery all the time. The electric heating switch, the piezoelectric press sensor and the rechargeable battery constitute a circuit loop. The invention has the advantages of convenient assembly and installation, easy carry, wide application and convenient use.

The invention discloses a liquid addition and atomization device for a mine nitrogen-filling process. A flow-guide atomization device is arranged at the front end of a barrel body of the liquid addition and atomization device. A reducing gas-guide channel is reserved in the interior of the flow-guide atomization device. A bypass channel is arranged between the exterior of the flow-guide atomization device and the barrel body. A flow inlet channel is arranged on a lateral side of the flow-guide atomization device, and is communicated with a liquid-guide groove. A Venturi mixer is arranged at the rear end of the barrel body; and an injection orifice of the flow-guide atomization device is opposite to a mixture channel of the Venturi mixer. The liquid addition and atomization device is simple in structure, large in atomization amount, small in occupied space, flexible in movement, convenient to assemble, capable of effectively preventing blocking and working continuously, suitable for viscous liquid, free of electric elements, safe, reliable, and wide in practicability, is applicable to fire preventing and suppression in gob area of a mine or a closed space, and especially is applicable to adding fire-proof inhibitor solution in a mine nitrogen-filling process for fire preventing and suppression.
