Document Type and Number:
WIPO Patent Application WO/2021/098838
Kind Code:
A1
Abstract:
A microbubble treatment agent cartridge assembly (52) and washing equipment having the microbubble treatment agent cartridge assembly (52). The microbubble treatment agent cartridge assembly (52) comprises a housing (521) and a treatment agent cartridge (522) accommodated in the housing (521). The housing (521) is provided with at least one water inlet pipe portion (525, 526). The at least one water inlet pipe portion (525, 526) is provided internally with at least one stage of diameter-decreasing tapered portion (252, 262) and a microbubble former (253, 263), and the pipe wall thereof is further provided with an air inlet hole (256, 266). The air inlet hole (256, 266) is positioned between the at least one stage of diameter-decreasing tapered portion (252, 262) and the microbubble former (253, 263), and communicates with an air inlet pipe (254, 264) disposed on the housing (521). The top of the most downstream stage of diameter-decreasing tapered portion (252, 262) is provided with a spray hole (255, 265). The spray hole (255, 265) is configured to enable the water flow flowing through the at least one stage of diameter-decreasing tapered portion (252, 262) to be expanded and sprayed through the spray hole (255, 265) and generate negative pressure near the air inlet hole (256, 266), so that air can be sucked into water inlet pipe portion (525, 526) from the air inlet pipe (254, 264) and mixed with the water flow to produce bubble water. The bubble water flows through the microbubble former (253, 263) to be turned into microbubble water, and is then sprayed into the treatment agent cartridge (522). Therefore, the dissolution of the treatment agent is accelerated.
