The present invention relates to a sprinkler for mist spraying, more specifically, to minimize the clogging of the nozzles due to foreign substances when spraying the chemical liquid, and the residual chemical liquid and foreign substances remaining in the mist spray nozzle portion, the body, the water pipe after use automatically through the discharge valve By discharging it, the spray nozzle can be operated smoothly even for long time use. Also, by periodically using low pressure raw water, the filter network built in the spray nozzle can be cleaned by itself, and the waste and foreign matters are automatically discharged through the discharge valve to add the cleaning function of the spray nozzle to solve the clogging problem. It is. When the sprinkler for mist spraying is connected to the supply pipe with a simple tool, and there is no protruding portion in the water pipe to facilitate the water flow, the effect of the chemical liquid flow is maximized at the time of spraying. The present invention is a sprinkler for spraying the chemical liquid supplied from the water pipe, "U" shaped opening groove 110 is formed on the upper side so that the outer periphery of the water pipe 10 is formed, the lower of the opening groove 110 A hollow body (100) having a hollow protrusion (120) formed therein so that the chemical liquid outlet (50) formed in the water pipe (10) is inserted into at least two sides of the body (100); Is formed in the inner passage is connected to the inner passage of the body 100 and the side spray sphere 200; Screwed to the side spray sphere 200, the chemical liquid supplied from the water supply pipe 10 to form a fog The mist spray nozzle unit 300 to be sprayed with; Screwed to the lower side of the body 100 remains in the water supply pipe 10, the body 100, the side spray hole 200, the mist spray nozzle unit 300 It consists of a discharge valve 400 for letting out residual chemicals and foreign substances .본 발명은 안개분무용 스프링클러에 관한 것으로, 보다 상세하게는 약액
