WATER GUN CLEARING APPARATUS AND METHOD

摘要

A water gun clearing apparatus, particularly for application in self-serve car wash units, for use in clearing standing water from hoses, pipes and the water gun as well as preventing residual water moisture from building-up within the water gun. The water gun clearing apparatus comprises an air regulation system connectable to a source of pressurized air, and a timer. The air regulation system comprises a first air line branch configured to provide a continuous supply of pressurized air at a first flow rate, and a second air line branch configured to provide a supply of pressurized air at a second flow rate. Following use of the water gun by a user, the timer activates and provides pressurized air to the water gun at the second flow rate for a pre-determined time period in order to clear residual water from the water line and water gun.

主权项

1. A water gun clearing apparatus comprising:
a water line connectable to a water source; an air regulation system connectable to a source of pressurized air, the air regulation system comprising a first air line branch configured to provide a continuous supply of the pressurized air at a first flow rate and a second air line branch comprising a gun clearing valve configured to provide a supply of the pressurized air at a second flow rate; a water gun connected to both the air regulation system and the water line; a one-way check valve configured to prevent back flow of water from the water line into at least the first air line branch when the water gun is in use; and, a timer activatable to provide a supply of the pressurized air to the water gun at the second flow rate for a pre-determined time period following use of the water gun in order to clear residual water from the water gun.
