PRESSURE ACCUMULATION TYPE FOAMING WASHER

PROBLEM TO BE SOLVED: To provide a pressure accumulation type foaming washer that generates a foam spray liquid with high adhesiveness to spray surfaces in a simple structure, and is advantageous in cost.SOLUTION: The pressure accumulation type foaming washer 10 includes: a tank 30 storing a spray liquid 20 containing a surfactant; a manual pressure accumulation pump 40 for raising the pressure in the tank; a liquid sending pipe 50 provided inside the tank to introduce the spray liquid; a liquid sending hose 60 provided outside the tank to communicate with the liquid sending pipe; a nozzle 70 provided at the tip of the liquid sending hose to spray the spray liquid; and an introducing member 80 provided inside the tank to introduce pressurized air in the tank into the liquid sending pipe. The foam spray liquid with bubbles grown by mixing air into the spray liquid through the introducing member is sprayed from the nozzle. The pressure accumulation type foaming washer further includes an adjustment means adjusting the opening area of the introducing member.
