Abstract

The present invention relates to a dual spray gun for painting and cleaning, and more especially to a combined tin and pipe dual spray gun for painting and cleaning, which can be used separately and independently, and increase the working radium at willing and can be used in unitized construction, depending on the working environments. The present invention includes a T-shaped main body, which is connected with an air blow-gun with the back end, and connected to a blow head with the front end, and secured a pipe on the vertical sucking tap hole, and a tank is connected on the tip end of said pipe to construct a combined tin and pipe structure; said tank can be connected on said T-shaped main body directly individually to construct a tin structure; if the pipe is connected on the T-shaped main body individually to construct a pipe structure; so the three structures can meet the necessaries of any working environment so that the working radium is extended infinitely.

Dependent claims

A dual spray gun for painting and cleaning comprised of a three-way T-shaped main body having an inlet tap hole for securing to an air blowgun via a combined bolt and a locating nut, and a front tap hole for securing a blow head, and the downward sucking tap hole connecting to said front tap hole, and a through-hole connecting said front tap hole and said sucking tap hole to said inlet tap hole for locating an atomized nozzle from the inlet tap hole side so that the tip end of said nozzle stretch in the inside of said front tap hole and above said sucking tap hole;

said sucking tap hole is used for securing on a pipe connection at one end of a pipe, and a filter connection holding a filter leaf for filtering foreign is built upon the another end of said pipe, and there is an internal screw built on the inside of said filter connection for securing on a bolt with a through-hole at the cap of a tank and sealing with an O-ring, and said combined bolt with a through-hole at the top side of said cap secures with said filter connection, and said cap extends a sucking tube from the bottom side connecting the through-hole of said combined bolt on the top side with top end for sucking up the paint or cleaner in the tank, and said cap also has a pair of pivoting holes for hanging on a handle for carrying over.
