In the present invention, when supplying nutrients including fertilizer to crops grown in a facility house such as a vinyl house, supplying a pest control agent, or supplying a supply such as water for moisturizing, the supply can be supplied in the form of mist. It relates to a multi-purpose mist type sprayer configured to be able to, and a supply container for receiving supplies is installed on a mobile cart with wheels, a handle and a ground, and a device room is formed on the upper part of the supply container, so that the entrance is narrow and the outlet is wide inside. A cylindrical guide tube is installed to form a mist maker that makes the supply into a mist form inside the guide tube, and a mist type sprayer is formed with a discharge tube installed at the outlet of the guide tube. and a water level sensor is installed on the upper surface, and the discharge pipe forms a condensate drain at the lower end of the main wall to communicate with the recovery port formed on the upper surface of the supply pipe, so that the condensate liquid flowing down from the discharge pipe passes through the condensate drain of the discharge pipe. It flows into the supply pipe and allows it to be recovered naturally, and a drain pipe whose outlet is lower than the floor level of the supply pipe is installed from the bottom of the supply pipe to the outside. It is formed to protrude so that the outlet of the first connection pipe is connected to the suction pipe of the electric pump, and the outlet of the second connection pipe is connected to the suction pipe of the agitation pump so that the pumping and agitation of the supply contained in the supply cylinder can be strong, It is configured to rapidly spread the supply supplied to the dispersion plate to the outer circumference of the dispersion plate by installing a spacer in the central supply part of the dispersion plate installed in the fog maker unit that makes the fog in the form of fog.

The applicant of the present application has developed a pesticide sprayer that sprays pesticides in a mist form, and has received patent registration as Invention Patent No. 10-1940031.
The above invention patent is a mobile cart with four wheels attached to the front and rear sides of the bottom and a handle on the rear, a pesticide container installed on the upper surface of the mobile cart, an equipment room installed next to the pesticide container, and a pesticide container installed on the top of the equipment room and accommodated in the pesticide container An electric pump that pumps pesticides and supplies them to the center of the dispersion plate of the mist making unit through spray nozzles, a guide tube installed in the equipment room and having a trumpet-shaped cylindrical body with a narrow inlet and a wide outlet, and a discharge pipe coupled to the outlet, and a guide tube A blower installed at the entrance to rotate at high speed with the power of a motor and supplying wind of a certain intensity to the guide tube, and a plurality of dispersing plates disposed at the center of the guide tube by forming an attachment plate at the end of the rotating shaft of the motor to which the blower is attached, A net installed on the outer circumference of the distribution plate disperses the pesticide supplied to the center of the distribution plate to the outer circumference of the distribution plate and filters it with a filter net formed on the main wall, and the wind of the blower is combined with the pesticide discharged to the guide tube through the filter net on the main wall of the netton It is configured to make the pesticide into a mist form by having a mist maker that makes it into a mist form and supplies it to the facility house where the crops are planted through the discharge pipe.

Therefore, in the fog-type pesticide that is made in the form of mist in the guide pipe and supplied to crops through the discharge pipe, some of the mist-like particles contact the inner surface of the discharge pipe in the step of passing through the discharge pipe, resulting in condensation, and the condensation liquid along the peripheral wall of the discharge pipe. It flows down to the lower end of the discharge pipe, and the condensate that flows down is collected in the collector installed at the lower end of the discharge pipe, and when the amount increases, the second electric pump installed separately in the equipment room is operated to pump the condensate collected in the collector. It is sent back to the pesticide container, so it is inconvenient to collect the condensation solution,

In addition, since the electric pump pumping pesticides and supplying them to the center of the dispersion plate of the mist maker installs an equipment room next to the pesticide container installed on the mobile cart and installs it high on the upper surface of the equipment room, a connection pipe is installed in the suction pipe of the electric pump. It is configured to connect the lower end of the connecting pipe to the pesticide container, and since the pesticide container does not have a water level sensor that detects the lowest level of the pesticide, when the pesticide contained in the pesticide container is pumped and sprayed, even if the pesticide contained in the pesticide container is exhausted It is not immediately possible to know the fact, and since the electric pump continues to operate without knowing that the pesticide is exhausted, the pesticide is not sucked into the suction pipe of the electric pump, and air enters the pesticide container. When refilling and spraying, it is inconvenient to remove the air introduced into the suction pipe of the electric pump, and the moving cart has four wheels arranged on the front and back, and there is no grounding interval, so the moving cart is placed between narrow furrows. When it enters, it is difficult to change the direction and it is difficult to fix a certain position, and a separate blowing fan is installed on the upper surface of the equipment room to diffuse the mist-type pesticide ejected through the discharge pipe into the facility house, but the installation direction is fixed There is a slight inconvenience in the spraying effect, and when attaching the dispersion plate of the mist maker to the end of the rotating shaft of the motor, it is difficult to assemble because a washer must be inserted between the gaps to maintain the gap, and the pesticide container does not have a pesticide stirring device, so the precipitation of the drug may occur. At that time, there was an inconvenience that could not be resolved.
