Zusammenfassung:The present invention relates to a reagent spraying apparatus comprising: a support portion installed on a region where the apparatus is to be installed; a reagent container portion installed at one side of the support portion to accommodate a reagent inside; a spraying portion installed at one side of the support portion to be able to vertically move and having one side thereof connected to the reagent container portion, into which the reagent is introduced to spray the reagent on the inner surface of a test container; a valve unit installed on a channel of the reagent, through which the reagent is transferred from the reagent container portion to the spraying portion and having one side thereof connected to one side of the reagent container portion, wherein the valve unit opens the channel through which the reagent is transferred to the spraying portion in a spraying mode, and opens a circulation path through which the reagent is transferred to the reagent container portion in a circulation mode; and a circulation unit interposed between the reagent container portion and the valve unit on the channel of a reagent to pump the reagent into the valve unit in the circulation mode. According to the present invention, the circulation unit and the valve unit are installed at one side of a channel through which a reagent is transferred from the reagent container portion to the spraying portion to make the reagent transferred to the reagent container portion when a spraying process is being performed and make the reagent circulated when the spraying process is stopped, thereby enabling the reagent to be uniformly applied to the inner surface of the test container to greatly enhance reliability of an analytical test regardless of the level of the reagent accommodated in the reagent container and preventing substances of the reagent from being separated in advance, to allow uniform spraying of the reagent without separation of reagent substances. 본 발명은 시약분사장치에 관한 것으로서, 설치대상영역에 설치되는 지지부와, 상기 지지부의 일측에 설치되고, 내부에 시약이 수용된 시약용기부와, 상기 지지부의 일측에 상하방향으로 이동가능하게 설치되고, 일측이 상기 시약용기부와 연결되어 상기 시약이 내부로 인입되며, 상기 시험용기 내면에 시약을 분사하는 분사부와, 상기 시약이 상기 시약용기부로부터 상기 분사부로 이동되는 시약의 이동경로 상에 설치됨과 아울러 일측이 상기 시약용기부 일측에 연결되고, 분사모드에서 상기 시약이 상기 분사부로 이동되는 이동로를 개방하며, 순환모드에서 상기 시약이 상기 시약용기부로 이동되는 순환로를 개방하는 밸브유닛 및 상기 시약의 이동경로 중 상기 시약용기부와 상기 밸브유닛 사이에 설치되고, 상기 순환모드에서 상기 밸브유닛으로 상기 시약을 압송하는 순환유닛을 포함하는 것을 특징으로 하는 시약분사장치를 제공한다. 상기와 같은 본 발명에 따르면, 시약용기부로부터 분사부로 이동되는 시약의 이동로 일측에 순환유닛 및 밸브유닛을 설치하여 시약 분사작업 실행중에는 시약
