Claim Text:
1. A solenoid valve having an air tap structure comprising: a plunger head; an actuating device having a connection member coupled with the plunger head for moving the plunger head; a seal sheet disposed on the actuating device around the connection member; and an air tap assembly secured to the actuating device comprising: a main body having a cavity for accommodating the plunger head; a first tube protruding from an outer surface of the main body and defining a first through hole that extends therethrough, the main body defining a second through hole communicated with the first through hole and with the cavity, the first and second through holes being located along a central axis of the main body; and a second tube protruding from the outer surface of the main body at an angle thereof such that the second tube is not parallel with the first tube, the second tube defining a third through hole that extends therethrough, the main body defining a fourth through hole that is extended from the third through hole by a distance and a fifth through hole that is extended from the fourth through hole to the cavity to thereby communicate the third through hole and the fourth through hole with the cavity, the fifth through hole being parallel to the second through hole; wherein the main body is formed with a circular opening on a bottom surface thereof, the circular opening surrounding the second through hole and communicating with the cavity and the fifth through hole; and wherein a top surface of the plunger head is used to seal the openings of the second and fifth through holes, and the circular opening, wherein the actuating device comprises: a valve core connected with the connection member, and the seal sheet is disposed on the valve core; a spring located partly within the valve core; a base connected with a bottom of the valve core via the spring; a coil rack covering the valve core and the base, an outer part of the coil rack being surrounded with copper wires; a housing covering the outer part of the coil rack; and two copper contacts, a top of each of the copper contacts being connected with a bottom of the coil rack, and a bottom of each of the copper contacts being connected with a power supply unit for an application of an electric current to the copper wires around the coil rack, wherein an outer surface of a lower part of the connection member is formed with an external screw thread, and the valve core is formed with a hole and an internal screw thread in the hole, wherein the valve core is coupled with the connection member through engagement between the screw threads.
