(1) The medicine liquid pressed into the high pressure fog machine can be sprayed at one time, do not pressurize in the middle, and the self-locking device will automatically lock the air to remind the user to turn off the spray switch after the medicine liquid is sprayed, so that the liquid can be sprayed. A certain preset air pressure is reserved in the air tank for the next cycle.

(2) The user can upgrade and expand the capacity if the water capacity is small, and there is no need to put the original high pressure fog machine aside for repurchase.

(3) The high pressure fog machine itself is equipped with a safety valve and an air pressure gauge, which can not only intuitively know the pressure in the liquid and gas tank, but also automatically release the excess pressure when the pressure in the liquid and gas tank exceeds the specified value, so as to ensure that the high pressure fog machine will not be overpressured damage.

(4) The coarse spray range of the high pressure fog machine reaches 7 to 9 meters, and the efficiency of the fine spray is 2 to 4 times higher than that of ordinary high pressure fog machines.
