1. A micro-bubble treatment agent box assembly, comprising a housing and a treatment agent box accommodated in the housing, wherein:
at least one water inflow pipe part is provided on the housing, and at least one of the at least one water inflow pipe part is provided therein with an at-least-one-stage diameter-decreased conical part and a micro-bubble bubbler; a pipe wall of the at least one of the at least one water inflow pipe part is also provided with an air inflow hole; and the air inflow hole is positioned between the at-least-one-stage diameter-decreased conical part and the micro-bubble bubbler and communicates with an air inflow pipe provided on the housing; and
a spray hole is provided at a top end of a most-downstream-stage diameter-decreased conical part; the spray hole is arranged such that a water flow flowing through the at-least-one-stage diameter-decreased conical part can be expanded and sprayed through the spray hole and generate a negative pressure near the air inflow hole, so that air can be sucked into the water inflow pipe part from the air inflow pipe and mix with the water flow to generate bubble water; and the bubble water flows through the micro-bubble bubbler to become micro-bubble water, which is then sprayed into the treatment agent box.
