[Prior Art] As shown in Figs. 1, 2', there is a solenoid valve 10 suitable for a lock (not shown) having a circular dome 11 surrounding an axis and forming a chamber 1U. A magnet 12 fixed in the chamber ill and located at the bottom of the casing 11 is mounted with a bobbin 13 fixed in the chamber 1U along the axis I, and a bobbin 13 wound around the bobbin 13 The coil 14 is embedded with a coil guide 15 fixed between the bobbin 13 and the casing 11, and is movable in a central hole 131 of the bobbin 13 so as to be movable along the axis I. a member 16, a spring cymbal mounted in the central hole 131 and resiliently abutting the movable member 16, a fixed cover 18 fixed in the housing 11 and being pushed by the spring 16, and a hinge along the axis I The fixing cover 18, the spring 17 are sequentially passed through and the piston rod 19 of the movable member 16 is screwed. The housing π has a slot 112 disposed from the top end toward the bottom end. The bobbin 13 has a tube portion 132 surrounding the axis and forming the central hole j 31, a bottom convex ring 133 and a top convex ring 134 respectively formed from the tube portion 132, and a along the axis I The recess 135 is disposed on the top collar 134 and aligned with the slot 112. The coil 14 is wound around the tube portion 132 and located between the bottom convex ring 133 and the top crown ring 134, and has two lead wires 141 extending from the slot n of the housing 11. The coil guide 15 has an inner block 1316999 151 for inserting into the recess 135, and a connecting block 152' extending from the inner block 151 for inserting into the slot 112. The outer block 153' extending from and contacting the casing 152', a guide block 154 extending from the outer block 153, and a through hole 155 radially provided for the lead wire 141 of the coil 14. The fixing cover 18 has a plunger 181 inserted into the center hole 131 of the bobbin 13 , and a top convex ring 134 and the inner block 151 formed by the insertion post 181 for pressing the bobbin 13 . Pressure ring 182. The piston rod 19 is a switching member (not shown) for driving the lock. In use, when a current is supplied to cause the coil 14 to generate an electromagnetic field, the movable member 16 can be induced to become an electromagnet, which can be magnetically or repelled by the magnet 12 to move along the axis and away from or Close to the fixing cover 18, the piston rod 19 can be driven to extend or retract, and the switching member can be driven to perform the switching operation.

Because the top ring 134 of the bobbin 13 needs to be disposed along the axis I for the embedded block 151 of the coil guide 15 to be embedded, the top ring 134 must have a suitable thickness. In the case where the overall height of the bobbin 13 is uniform, the distance L1 between the top ring 134 and the bottom ring 135 is relatively short, resulting in a small number of windings of the coil 14, and finally The solenoid valve 1〇 can carry a small range of current losses. 2. When assembling, the inner block 151 of the coil guide 15 is first inserted into the 5 slanting groove 135. At the same time, the connecting block 152 enters the slot 112, and the plug of the fixing cover 18 is inserted. The 181 is inserted into the center hole 131, and the pressure ring 182 is pressed against the top ring 134 of the bobbin 13 and the inner block 15 1316999 to position the coil guide 15, which is more time consuming and assembly. More leads to the lack of higher costs.

The above-mentioned 'electromagnetic enthalpy of the present invention has the following effects and advantages', so that the object of the invention can be achieved: 1. Because the wire guide 74 of the present invention extends directly from the cover 71 into a cymbal, the one is integrated into one design. In contrast, the top ring 43 of the bobbin 40 does not need to be provided with a slot for the wire guide 74 to be embedded. Thus, the thickness of the top ring 43 can be effectively reduced, and the top ring 43 can be relatively increased. The distance L2 from the bottom convex ring 44 can further increase the number of windings of the coil 50, so that the present invention has the advantages and advantages of being able to carry a large range of current. 1. Because the wire guide 74 of the present invention is directly formed from the cover 71, the two are integrally designed. Therefore, the cover 71 only needs to be mounted and fixed in the chamber _21 of the sinister housing 20. At the same time, the top ring 43 of the bobbin 4 is pressed, and the bump 72 is inserted into the slot 24 of the casing 20, and the assembly of the components can be completed by 11 1316999. Assembly man-hours and the effectiveness and advantages of reducing the number of components to reduce costs.
