Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0019] In the present invention, unless otherwise clearly specified and limited, the terms "install", "connect", "connect", "fix" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements.

[0021] Example:

[0022] like Figure 1 As shown, an armature structure for shortening the response time is applied to various types of solenoid valves. It is an armature multi-slit structure for shortening the response time, including an armature body 1. The armature body 1 is provided with radial grooves 11. The radial grooves 11 are through grooves along the axial direction. The radial grooves 11 are evenly distributed and symmetrical along the circumference, and the connection between the outer ends of the radial grooves 11 and the outer circle of the armature body 1 is an opening.

[0023] The utility model has radial grooves 11, and when the armature is energized, the eddy current path of the cross section is intercepted and the eddy current is detoured, thereby extending the eddy current path of the cross section and reducing the response time of the armature. The radial grooves 11 are symmetrical so that the armature is symmetrical when in use, and will not be overweight, thereby preventing jamming caused by deflection. The radial grooves 11 are open on three sides, so that the eddy current can be forced to detour and extend the path.

[0024] The length L between the inner end of the radial groove 11 and the outer circle of the armature body 1 is less than the radius of the armature body 1. The radial groove 11 can extend the eddy current path and will not block the eddy current, so that the armature can be used smoothly.

[0025] The two side walls at the outer end opening of the radial groove 11 are both provided with expansion grooves 12. The width of the expansion grooves 12 is greater than the width of the radial grooves 11. The expansion grooves 12 are through grooves along the axial direction, and the two expansion grooves 12 are symmetrical. The expansion grooves 12 and the radial grooves 11 are of a structure that is larger outside and smaller inside. The inner wall of the expansion grooves 12 is a concave arc surface. The expansion grooves 12 occupy a part of the armature body, allowing the eddy current path to be extended again. Moreover, the expansion grooves 12 are arranged at the outer end without occupying the inner end area. While extending the eddy current path, the heat dissipation effect can also be increased.

[0026] like Figure 2 Shown is Figure 1 A top view of Figure 3 Shown is Figure 1 Another top view, the width of the inner end A of the radial groove 11 is equal to or smaller than the width of the outer end B, Figure 2 The width of end A is smaller than that of end B. Figure 3 The width of end B is equal to the width of end B.

[0027] like Figure 4 Shown is Figure 3 Schematic diagram of the eddy current path. In the past, the eddy current path was a circular ring, while the eddy current path of the present armature is a winding shape, which greatly extends the eddy current path and increases the response time.

[0028] The utility model is provided with a plurality of radial grooves 11. In this embodiment, the number of the radial grooves 11 is 12, which can reduce the weight of the entire armature. After the weight is reduced, the response time is further reduced.

[0029] The utility model increases radial grooves of the armature in the circumferential direction, prolongs the eddy current path of the cross section, and reduces the weight of the armature, thereby reducing the response time; during the test, the response time is shortened by 15%.

[0030] The above description is only a preferred implementation mode of the present invention, and does not limit the present invention in any form. Any simple modification, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are within the scope of the technical solution of the present invention.
