PROBLEM TO BE SOLVED: To provide a knapsack type mist blower which includes an opening/closing valve and a filter in a liquid feed pipe and prevents a liquid from adhering to the hand of a worker when the filter is detached.SOLUTION: A knapsack type mist blower 10 includes: a knapsack frame carried by a worker on his/her back; a blower unit 20 mounted on the knapsack frame and blowing air from a blowing duct; a tank 30 mounted on the knapsack frame and storing a liquid; a blower pipe 24 connected with the blowing duct of the blower unit 20; a liquid feed pipe 34 led out from a lower part of the tank 30 to a tip of the blower pipe 24; an opening/closing valve 35 opening/closing a pipe line of the liquid feed pipe 34; and a filter 36 removing foreign materials contained in the liquid fed from the tank 30. The opening/closing valve 35 is arranged at a higher position than a liquid face in the tank 30 when the tank is filled with liquid in normal use and the filter 36 is disposed on a downstream side of the opening/closing valve 35, in a state where a tip of the blower pipe 24 is erected vertically so as to be positioned at a higher position than the other parts.SELECTED DRAWING: Figure 3 |
