Further, the inner box has an open end tube that keeps the second water inlet in communication with the bottom chamber and isolated from the inner box. Further, the cover has a first water outlet below the elevation of the first water inlet. The aisle is disposed in communication with the space outside the housing via a second water outlet that is disposed below the elevation of the second water inlet. ## Claims ### Claim 1 A stacked type quantitative toilet cleaning agent dispenser, comprising: a housing having an arcuate sidewall, an open top side, and an opposing closed bottom side for positioning on a surface; an inner box mounted in said housing such that a bottom chamber is defined within said housing between an outer bottom surface of said inner box and an inner bottom surface of said housing and an aisle is defined between an inner perimeter of said housing and an outer perimeter of said inner box and disposed in communication with said bottom chamber; and a cover covering said inner box with a top of said cover exposed on the outside of said housing, said cover comprising a first water inlet and a second water inlet, said first water inlet being disposed in communication with a space inside said inner box; wherein: said inner box comprises an open end tube, said open end tube having a first end connected to said cover and disposed in communication with said second water inlet and an opposite end inserted through said inner box and disposed in communication with said bottom chamber to keep said second water inlet and said bottom chamber in communication with each other and to isolate said second water inlet and said bottom chamber from said inner box; the stacked type quantitative toilet cleaning agent dispenser further comprises a first water outlet located in said cover for allowing communication between a space inside said inner box and the space outside said inner box, said first water outlet being disposed below a elevation of said first water inlet; said cover covers the said open top side of said housing; a second water outlet is located in said cover; for allowing communication between a space outside said housing and said aisle, said second water outlet being disposed below a elevation of said second water inlet. ### Claim 2 (depends on 1) The stacked type quantitative toilet cleaning agent dispenser as claimed in claim 1, wherein said cover further comprises a recess inwardly sloped from a top surface of said cover; said first water inlet and said second water inlet are respectively located in a bottom wall of said recess. ### Claim 3 (depends on 2) The stacked type quantitative toilet cleaning agent dispenser as claimed in claim 2, wherein said cover further comprises a partition plate located on the top surface of said cover and dividing said recess into two sub-recesses, said two sub-recesses being isolated from each other and corresponding to said first water inlet and said second water inlet, respectively. ### Claim 4 (depends on 1) The stacked type quantitative toilet cleaning agent dispenser as claimed in claim 1, wherein said first water outlet extends through said cover. ### Claim 5 (depends on 1) The stacked type quantitative toilet cleaning agent dispenser as claimed in claim 1, wherein said open end tube is shaped like a cone, having an inner diameter which increases from the first end toward the opposite end. ### Claim 6 (depends on 1) The stacked type quantitative toilet cleaning agent dispenser as claimed in claim 1, further comprising a lifting partition plate vertically movably mounted in said inner box and attached to said open end tube, said lifting partition plate covering at least 90% of the cross-sectional area of said inner box, said lifting partition plate comprising a plurality of through holes. ### Claim 7 (depends on 1) The stacked type quantitative toilet cleaning agent dispenser as claimed in claim 1, further comprising a decorative lid covering said cover, said decorative lid comprising a plurality of openings. ### Claim 8 (depends on 7) The stacked type quantitative toilet cleaning agent dispenser as claimed in claim 7, wherein said cover covers said inner box and said housing. ### Claim 9 (depends on 1) The stacked type quantitative toilet cleaning agent dispenser as claimed in claim 1, wherein said housing comprises a mounting portion located at a perpihery. ### Claim 10 (depends on 1) The stacked type quantitative toilet cleaning agent dispenser as claimed in claim 1, wherein said opposing closed bottom side is a curved wall, and a counterweight accommodated in said bottom chamber and supported on said curved wall. ### Claim 11 (depends on 10) The stacked type quantitative toilet cleaning agent dispenser as claimed in claim 10, wherein said housing further comprises a plurality of extension walls protruding inwardly from an inner surface of the bottom chamber, the plurality of extensions walls abutting against said counterweight to hold said counterweight in place. ### Claim 12 (depends on 1) The stacked type quantitative toilet cleaning agent dispenser as claimed in claim 1, further comprising a middle box mounted in said bottom chamber and attached to a bottom wall of said inner box, said middle box comprising a connection tube, said connection tube having a first end inserted into said open end tube and disposed in communication with said open end tube and an opposite end inserted through said middle box and kept in communication with said bottom chamber so that said second water inlet and said bottom chamber are kept in communication with each other via said open end tube and said connection tube and isolated from said inner box and said middle box; said middle box further comprises a third water outlet to keep a space inside said middle box being in communication with the space outside said middle box; said middle box has an outer perimeter which with the inner perimeter of said housing, defines a middle aisle therebetween; said cover further comprises a third water inlet; said inner box further comprises a second open end tube, said second open end tube having a first end connected to said cover and disposed in communication with said third water inlet and an opposite end inserted through said inner box and kept in communication with said middle box so that said third water inlet and said middle box are kept in communication with each other and isolated from said inner box. ### Claim 13 (depends on 12) The stacked type quantitative toilet cleaning agent dispenser as claimed in claim 12, wherein said cover further comprises a recess inwardly sloped from a top surface of said cover;
