[Industrial applications]

 The present invention relates to a cleaning device equipped with a nozzle that sprays various kinds of cleaning water toward an object to be cleaned.

[0002]

[Prior Art]

 In recent years, car owners who do not have a car wash space at home go to a coin car wash yard equipped with a spray-type washing device to wash their cars. The spray-type washing device installed in this car wash area is configured to inject high-pressure washing water from the nozzle toward the vehicle so that the vehicle can be washed. By the way, car owners tend to take time to wash their hands with the increasing quality of cars, and against this background, manufacturers have the function of hand-washing by spraying a foaming detergent. We are considering a cleaning device built into the device.

[0003]

[Problems to be solved by the device]

 However, when a foaming detergent is sprayed using the pump and nozzle provided in the conventional cleaning device, the foaming property of the detergent is poor because the spraying pressure is high and the flow velocity is high, and even if the spraying pressure is reduced, Sufficient foam could not be obtained because of its small diameter. The present invention has been made to address such problems, and an object of the present invention is to provide a cleaning device capable of improving the foamability of a detergent and performing effective cleaning.
