Abstract:
1. A multi-color paint application apparatus comprising: a paint storage portion having a number of paint containers in the inside of a storage body; a cover portion that can open and close the upper side of the storage body of the paint storage portion, in which a fixing board which is bent to one side of a fixing body is fixed on the upper surface of the cover portion and fastening rings are formed around the upper edge of the storage body, to thereby make the storage body sealingly closed when the fastening rings are rotated; a discharge portion which comprises discharge tubes which are penetratively formed on the upper surface of the cover portion and which are communicated with the number of paint containers, auxiliary containers which are provided on the upper portion of the discharge tubes and store respective paints discharged through the discharge tubes, and paint discharge valves that are fixed to the fixing board at the outside of the auxiliary container in which the paint discharge valves are connected with the discharge tubes through connection tubes; a sensor portion having sensors which are respectively fixed to the discharge tubes in the discharge portion and including contacts that are short-circuited if a paint level is fallen in the paint containers, in which an alarm sound is produced by a buzzer if electric power is short-circuited; an air inlet portion including a 3-way valve which makes pressure of air selectively flow into the center of the cover portion so that compressed air flows into the paint storage portion in order to discharge paint to a number of paint discharge valves via a connection tube which connects the discharge tubes of the discharge portion with the paint discharge valves in which the discharge portion communicates the paint containers where the sensors of the sensor portion are built in; a dehumidification portion which is connected with an expansion tube where a drain plug that can remove moisture by adiabatic expansion of the compressed air is formed the 3-way valve in the air inlet portion, in which a connection valve where a pressure gauge is formed is connected with the expansion tube; a spray gun which can selectively spray the compressed air through a switch formed in a handle lever, by connecting a compressed air inlet tube with the 3-way valve in the air inlet portion connected with the dehumidification portion to then be connected to the handle lever, and by connecting a nozzle and a connector with respective paint discharge tubes in the number of paint discharge valves a carriage unit which comprises an accommodation body that can accommodate the body of the paint storage portion in the upper portion of the carriage unit, a body grip which is formed at both sides of the accommodation body, and a carrier caster which is formed at the lower portion of the carriage unit.
