Based on the provided white-background product images, generate a detailed poster for the portable oral irrigator. The background shifts from misty blue to white, with quiet pale blue ripples spreading at the bottom. In the upper left, use deep indigo sans-serif lines with two lines of title: "Fresh Large Water Tank / Easy to Clean and Disassemble," and two lines below explain: "Transparent water storage tank, just twist and you can separate and clean it." A white water flosser is placed vertically in the center, with a transparent light blue water tank clearly visible and the nozzle fully exposed.
On the left side, there is a rounded magnified window showing the water tank rotating and being removed and rinsed under flowing water; Set up a rounded magnified window on the right side, showing that after opening the water filler, clean water is poured in. The two windows are labeled "Screw and removable / Easier daily cleaning" and "Wide mouth water injection / Clear and efficient operation," with thin dashed lines leading to the corresponding parts. The product retains a white body and a transparent water tank core structure, with adjustable button arrangement, nozzle proportions, and tank contours. The product originally included brand information, using only "MOCKUP" and "EMBRACE YOUR BEAUTY, UNLEASH YOUR POWER." Avoid original branding, capacity numbers, medical effects, fine footnotes, watermarks, and obvious text shadows.
