Referring to fig. 7, the solenoid valve assembly 103 includes a bracket, an "i" shaped attraction iron core 120, an encapsulated coil 110 wound around the attraction iron core 120 for turning on and off, a moving iron hook 150 for attracting or separating with the attraction iron core 120 under the condition of turning on and off, and a vertical hook 160 moving up and down to slide, rub and hook with the moving iron hook 150. The circuit board 1010 is used for controlling the moving iron hook 150 to suck. The h-shaped suction core 120 includes a vertical winding portion 123, a laterally disposed overlapping portion 124 located above the winding portion 123, and a laterally disposed abutting portion 125 located below the winding portion 123. The moving iron hook 150 includes a fixed shaft 153, an attraction portion 1511 located at one end of the fixed shaft 153 for attracting or separating with the attraction iron core 120, and a hook 1520 located at the other end of the fixed shaft 153. The moving iron hook 150 is pivotally connected to a bracket (not numbered) for attracting the attraction iron core 120.

Referring to fig. 7, the moving iron hook 150 is substantially in the shape of a lever, and includes a power arm 151 for attracting the attracting iron core 120, a resistance arm 152 for hooking and connecting with the hook 160, and a fixed shaft 153 pivotally connected between the power arm 151 and the resistance arm 152 and fixed to the bracket and abutting against the abutting portion 125 of the attracting iron core 120. Thus, an electromagnetic circuit can be formed between the attraction iron core 120 and the power arm 151, and when the coil 110 is powered on, the overlapping part 124 of the attraction iron core 120 can maintain the attraction state with the power arm 151. In other embodiments, the attraction core 120 may have other shapes.

Referring to fig. 7, a spring 130 is disposed at the center of the side of the power arm 151 to support and assist the moving iron hook 150 in reciprocating motion. So configured, the spring 130 can support the power arm 151 of the moving-iron hook 150 and assist the moving-iron hook 150 in reciprocating motion. The bracket is provided with a reset mechanism mounting portion 140 at a central position of the resistance arm 152 for mounting a reset mechanism (not shown) for preventing the hook 160 from being locked when moving upward. The attraction iron core 120 is provided with an attraction surface 121, and the power arm 151 is provided with an attraction portion 1511 for attracting the attraction surface 121.

When the intelligent jacquard machine capable of automatically detecting abnormality is operated, the hook 160 reciprocates up and down by the driving of the knife 1013 (described below). One cycle goes through the following processes:

The hook 160 moves upwards, the hook 161 impacts on the hook portion 1520 of the moving iron hook 150 and moves upwards along the hook inclined surface 15201 to be hooked with the hook portion 1520, meanwhile, the lateral extension arm 162 of the hook 160 acts on the hook portion 1520 of the moving iron hook 150 and continuously moves upwards, the moving iron hook 150 and the iron core are attracted by utilizing the lever principle, and meanwhile, the coil 110 is electrified, so that the attraction state is kept. When the carabiner 160 moves upward to the top, the downward restoring force of the return mechanism carabiner prevents the carabiner from falling into dead corners and reduces the time that the carabiner stays at the top position. And is pulled down by external force before the coil is powered off, namely the moving iron hook is reset.

The length of the power arm 151 in the vertical direction corresponds to the length of the winding portion 123, and in the present embodiment, the length of the power arm 151 in the vertical direction is greater than the length of the resistance arm 152 in the vertical direction. With such an arrangement, the length of the winding portion 123 can be increased, so that the function and the service life of the attraction iron core 120 are both optimized, and meanwhile, the upper end part of the electromagnetic valve assembly 103 keeps the original size in the vertical direction, and the trend of miniaturization of the jacquard electronic valve assembly is avoided. The spring 130 is mounted between the wire winding portion 123 and the power arm 151. With such an arrangement, the moving iron hook 150 has a strong restoring elastic force to move outward.

In this embodiment, a connection portion 1620 connected to the extension arm 162 is disposed below the hook 161, and when the extension arm 162 is pressed against the power arm 151 and deformed downward, the extension arm 162 contacts the connection portion 1620, the upper surface of the connection portion 1620 is inclined, and the lower surface of the connection portion 1620 is formed in an arc shape with a downward opening, so that the extension arm 162 has a good strength to support the hook portion 1520 of the moving iron hook 150, thereby preventing the extension arm 162 from collapsing or breaking.

The extension arm 162 is further provided with an outer protrusion 16201 extending outward from the connection portion 1620. With this arrangement, the outer protrusion 16201 may have a sufficient length to support the hook 1520 of the hook 150 against the hook 160 to prevent the hook 160 from falling into a dead space upward.
