The invention relates to a children's product, in particular to a disposable child paper diaper compressing device. According to the disposable child paper diaper compressing device, paper diapers arecollected and treated intensively, the sanitary cleanliness is high, and the use effect is good. The disposable child paper diaper compressing device comprises a bottom plate and the like. A treatingbox is arranged at the top of the bottom plate, and a compressing frame is arranged at the top of the treating box. A through hole is formed in the right side of the compressing frame, and a guidingplate is obliquely arranged at the bottom of the position, provided with the through hole, of the compressing frame. A pushing mechanism is mounted at the top of the compressing frame, and clamping mechanisms are symmetrically mounted on the left side and the right side of the bottom of the compressing frame. Through mutual cooperation of the pushing mechanism and the clamping mechanisms, the disposable child paper diapers are collected and compressed, and meanwhile through optimizing of a spraying mechanism, the effects that the use effect is good, the paper diapers are collected and treatedintensively, and the sanitary cleanliness is high are achieved.
