Support on cleaning device and cleaning device

Abstract

A support on the cleaning device includes trays; a water outlet channel is formed on each tray; a height difference is formed between two sides of the water outlet channel, such that when flowing in a direction from high to low, a fluid m the tray and used for cleaning can cross the water outlet channel and is kept from flowing out through the water outlet channel, and when the fluid in the tray flows in a direction from low to high, the fluid can flow out through the water outlet channel. The height difference formed between the two sides of the water outlet channel is used to combine cleaning and scraping of the cleaning device by the tray with discharging of the fluid; the cleaning device is scraped clean by a high end formed by the height difference.
