An atomization device including a pair of counter-rotating rollers, a fluid source configured to coat at least one of the rollers in a feed fluid, and a baffle unit. The counter-rotation of the rollers stretches the feed fluid into a fluid filament between the two diverging surfaces of the rollers. The stretched fluid filaments breaking into a plurality of droplets at a capillary break-up point of the feed fluid. The baffle unit introduces a baffle fluid within the interior of the device, the baffle fluid transporting formed droplets of the feed fluid from the atomization device. Excess or misguides atomized fluid droplets are collected by the baffle unit and are recycled back into the device for use in later atomization processes. The variation of atomization device parameters allows for the selection of droplets having desired physical parameters.

Disclosed is a heatable portable irrigator, relating to the field of bathroom devices, which aims to solve the problems of no heating function and bulky size of a traditional irrigator. The irrigator adopts a split-type design, including a base, a liquid storage cavity, and a spray head module. The base is internally provided with a heater, a first battery, and a control circuit, which can heat a liquid to 383 C. The spray head module includes an independent battery, a water pump and a rotatable folding arm, which can extract the heated liquid and spray it out through a water outlet spray head. The spray head module is internally provided with a water volume detection system, and is automatically stopped when there is a water shortage. The base is provided with a waterproof charging port and a display screen, and the spray head module can be used independently.
