Recently, various problems such as heat waves, drought, landslides, ecosystem changes, typhoons, heavy rain damage, and sea level rise are occurring due to the influence of domestic and foreign climate change. This is a factor that can have a great impact on human life, and among them, the damage caused by the summer heat wave is increasing in severity in urban areas. The temperature is noticeably higher in metropolitan areas than in other surrounding areas, which causes various problems, including citizens' discomfort and lowering of thermal comfort, in urban areas.

On the other hand, damage caused by fine dust and yellow dust in downtown areas is increasing, and in particular, human casualties such as the occurrence of diseases due to high fine dust are occurring. Fine dust is classified according to particle size, and the constituents of the particles are toxic to the human body, and their size is very small and easily reaches the alveoli through the nose and airways. Systemic circulation is possible, which can increase human casualties. Accordingly, there is a demand for alternatives to reduce fine dust, but measures that are only a workaround to the extent of spraying water using a water sprinkler on the road are being implemented.

In order to cope with the recent urban heat wave and fine dust, a cooling fog system is being operated on a trial basis in urban parks, which are people's activity spaces. , it is used indiscriminately without evaluation of the user's thermal comfort and discomfort, and its utility is low in that it is used in limited places.

1 is a view showing a mist spraying device disclosed in Korean Utility Model Publication No. 20-0363828. The conventional fog spraying device may be installed for the purpose of increasing the mist spraying efficiency, removing foreign substances in the water, and then spraying it in the form of mist to lower the ambient temperature, such as parks and playgrounds.

However, in the case of a conventional mist spray device, a plurality of nozzles are provided for sufficient moisture supply. However, when supplying fluid to the nozzles, the arrangement of the piping is complicated and there is a problem that leakage is easy. Accordingly, there is a need for a mist spray nozzle in which the arrangement of the pipe from the pipe to the nozzle to which the fluid is sprayed is simple and the leakage is prevented when the fluid flows to the nozzle, and an injection device or system using the same.

In addition, when the state in which the relative humidity is very low, the humidity sensor 615 may detect it and spray the mist.

The fine dust concentration sensor 617 may be provided to detect the fine dust concentration around the sector or the mist injector 100 . In Korea, fine dust with a diameter of 10 μm or less is classified as fine dust, and those with a diameter of 2.5 μm or less are classified as ultra-fine dust. It can attach to the lungs and cause various diseases. The measurement of fine dust concentration is an investigation to understand the global pollution trend, and in many cases it is not measured near the surface. can be high Therefore, by measuring the concentration of fine dust around the mist injector 100, it is possible to spray the mist as a countermeasure against additional fine dust contamination.

The transmitting unit 63 may be provided to transmit data about the surrounding environment received by the environment sensing unit 61 . The data to be transmitted is transmitted to the central control means 70 to be described later, and the mist injection device 100 is controlled using the transmitted data.
