Anti-spray joint structure of connection hose of vehicle air compressor

An air compressor system comprising:

• a box including a body of an air compressor accommodated in the box and started by a power supply;
• a sealant supply can including an open segment extending downward and configured to accommodate chemical sealant for repairing a tire which is broken, and the sealant supply can including a supply tube;
• a connection hose including a first segment formed on a first end of the connection hose, and the connection hose including a second segment formed on a second end the connection hose, the first segment being connected with the supply tube of the sealant supply can, and the second segment being connected with an air nozzle of the tire;
• wherein the second segment has an anti-spray connector connected thereon, and the anti-spray connector includes a fitting sleeve, wherein the fitting sleeve has a threaded orifice formed in a first end thereof and having female threads, a through orifice defined on a second end of the fitting sleeve, and a projected shoulder formed on an inner wall of the through orifice, wherein a diameter of the projected shoulder is more than a diameter of the through orifice, and the threaded orifice is communicated with the through orifice;
• wherein a cylindrical base includes a cylindrical room, a stepped coupling segment extending on an outer wall of a second end of the cylindrical base, and a conduit defined in the coupling segment and communicating with the cylindrical room, wherein a diameter of the cylindrical room is more than a diameter of the conduit, and the cylindrical base further includes a first stepped portion formed between the cylindrical room and the conduit;
• wherein a first spring is received into the cylindrical room of the cylindrical base so that a first end of the first spring abuts against first stepped portion;
• wherein a valve bolt includes a post extending on a first end thereof, a connecting disc extending from a second end of the valve bolt, and multiple spaced slots defined around the post;
• wherein a first seal ring is fitted on the valve bolt;
• wherein the second end of the valve bolt is put into the cylindrical room of the cylindrical base to contact with a second end of the first spring;
• and
• wherein a lock element includes at least one tangent plane formed on an outer wall thereof, a stem extending from a first end of the lock element adjacent to the at least one tangent plane, a third stepped portion, and a hollow cavity defined in the lock element and the stem;
• and
• wherein the multiple spaced slots of the valve bolt passes through the hollow cavity of the lock element to locate in the threaded orifice, hence the first spring forces the first seal ring of the valve bolt to contact with a connection portion of the third stepped portion and the hollow cavity matingly.
