An ultrasonic atomization type electronic cigarette includes an ultrasonic atomizer having an ultrasonic atomization sheet, an electronic cigarette housing, an upper cover assembly, and a locking structure. The angle α between the ultrasonic atomization sheet and the central axis of the electronic cigarette is 5° to 85°, preferably 15° to 55°. The housing is provided with an air inlet groove. A first support in the housing includes a receiving cavity for receiving the ultrasonic atomizer. The upper cover assembly may be used for opening the receiving cavity, and the locking structure may be used for locking the upper cover assembly. A liquid guide structure in the atomizer may include a liquid guide body in which a side of a first liquid guide layer is sandwiched between a side of a second liquid guide layer and an ultrasonic atomization surface.

The present disclosure provides a spray device and a cleaning apparatus. The spray device includes an atomization structure, which is configured to atomize a cleaning liquid when the cleaning liquid is sprayed to form liquid droplets, and a jet structure, which is configured to spray a gas along a determined direction to cause the gas sprayed to collide with the liquid droplets to form atomized particles. The spray device provided by the present disclosure may increase cleaning uniformity and cleaning efficiency to improve cleaning process results, and may further reduce an impact force to the to-be-cleaned surface by the liquid droplets to a certain level. Thus, the damage to a surface pattern of a wafer may be reduced.

The invention relates to a refillable device (1) for spraying an active substance, comprising a reservoir (2) containing at least one active substance, said device (1) being equipped with a piezoelectric spraying mechanism (6). The invention also relates to the use of said device for spraying an active substance in a controlled manner from a distance in a desired direction. Said device is attached to the subject to be treated and can be used multi-directionally independently of the movements of the subject.

Methods and apparatus for electrostatic control of expelled material for lens cleaners are disclosed. In certain described examples, an apparatus can expel fluid by atomization from a central area of the surface using an ultrasonic transducer mechanically coupled to the surface. A first electrode can be arranged relative to the central area of the surface. A second electrode can be located in a peripheral area relative to the central area of the surface, in which a voltage can be applied between the first and second electrodes to attract atomized fluid at the peripheral area.
