This creative department provides a one-handed water sprinkler. The problem to be solved is that the user who exists in the conventional water spray gun must operate the water spray gun through both hands, and the operation is not convenient. The problem of inconvenient operation is improved and improved； the one-handed water sprinkler includes: the main system includes a handle, an outlet pipe and a valve body, and the inlet and the outlet pipe respectively form an inlet flow passage and a water outlet flow passage, and The valve body is disposed between the handle and the outlet pipe, and a valve cavity is formed inside the valve body, the valve cavity is respectively connected with the inlet water flow channel and the water outlet flow channel； and the control mechanism comprises a water flower control seat and a water inlet adjustment seat, and the water flower control seat And the water inlet adjusting seat is arranged side by side at the left and right ends of the valve chamber, thereby regulating the opening and closing of the water inlet, the flow rate and the opening and closing range of the water flower.本創作係提供一種單手操作之噴水器，其所欲解決之問題點，係針對習知噴水槍所存在之使用者必須同時透過雙手操控噴水槍其操作不甚便利等狀況，造成使用者作業不便之問題點加以改良突破；所述單手操作之噴水器其包括：主體係包括握柄、出水管及閥體，握柄及出水管內部分別形成有進水流道及出水流道，而閥體設置於握柄與出水管之間，閥體內部形成有閥腔，閥腔分別與進水流道及出水流道連通；以及控制機構係包括水花調控座及進水調節座，水花調控座及進水調節座分別並列組設於閥腔左右兩端，藉以調控進水之啟閉、流量大小及水花開合幅度。
