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.

The invention discloses a cigarette liquid storage device, an electronic cigarette atomizer and an electronic cigarette. The cigarette liquid storage device comprises a body, wherein a cigarette liquid guider is fixedly arranged on an outer wall on at least one side of the body; the cigarette liquid guider is communicated with an inner cavity of the body; a vent groove is formed in a surface, far away from the body, of the oil guider. The cigarette liquid storage device provided by the invention is provided with the oil guider; cigarette liquid can be directly conducted to an atomization component through the oil guider; the oil guider can be integrally molded with the body, and can be also fixed in ways of inlaying and the like; the cigarette liquid storage device is simple in structure and is convenient to use; the electronic cigarette atomizer which is provided by the invention adopts an ultrasonic atomization component, is high in capacity usage ratio, and solves a problem that the cigarette liquid heated by an existing heating wire easily generates a burnt smell and causes that a smoking taste becomes poor; meanwhile, the surface of the oil guider is provided with the vent groove which can not only allow a gas to pass through, but also can avoid a phenomenon of liquid leakage caused by too large contact area between a fluid guider and the ultrasonic atomization component; the cigarette liquid storage device, the electronic cigarette atomizer and the electronic cigarette are simple and exquisite in structure, and are convenient to mount and dismount.
