[0044] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present utility model will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0045] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0046] In the present invention, unless otherwise specified, the directional words used, such as "up, down, top, bottom", usually refer to the directions shown in the drawings, or to the components themselves in the vertical, perpendicular or gravity directions; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned directional words are not used to limit the present invention.

[0047] In order to solve the problem in the prior art that it is difficult for a plug to be accurately aligned with a socket of an installation device, and the plug is easily crooked or not properly plugged in, the utility model provides a solenoid valve assembly.

[0048] like Figure 1-4As shown, the utility model provides a solenoid valve assembly, including a solenoid valve 1 and a positioning unit 2, the solenoid valve 1 includes a coil unit 11, the coil unit 11 has a plug 111 for plugging and mating with an installation device, the positioning unit 2 is arranged on the plug 111, the positioning unit 2 includes at least two positioning columns 21 distributed along the axial direction of the plug 111, the central axis of the positioning column 21 is perpendicular to the axial direction of the plug 111, the positioning column 21 includes a sleeve-shaped column 211, an avoidance space 212 formed on the column and a flange 213 arranged on at least one side wall of the column, and the flange 213 extends in a direction away from the interior of the column.

[0049] With such arrangement, when the column 211 is inserted into the mounting hole of the mounting device, the flange 213 is squeezed so that the side wall connected thereto is recessed toward the avoidance space 212, thereby facilitating the insertion of the column 211 into the mounting hole. At least two positioning columns 21 spaced apart along the axial direction of the plug 111 can lock the position of the plug 111 relative to the mounting device, thereby preventing the plug 111 from being inserted crookedly or not properly inserted when mating with the socket due to the plug 111 not being fixed.

[0050] Typically, a tip is formed at one end of the column 211 away from the plug 111 to facilitate plugging the column 211 into a socket of an installation device.

[0051] The design of the avoidance space 212 is a key structural feature, which provides flexibility and adaptability of the column 211 during installation and use.

[0052] Specifically, refer to Figure 3-4 As shown, the avoidance space 212 is realized in the form of a through slot 2121, which extends along the central axis of the column 211 and penetrates the entire column 211 along a direction orthogonal to the axis of the plug 111. It can be understood that in this embodiment, the central axis of the column 211 is the central axis of the positioning column 21.

[0053] This design not only allows the column 211 to undergo a certain degree of elastic deformation when subjected to external force, thereby adapting to different installation environments and conditions, but also provides additional structural strength for the column 211. The presence of the through slot 2121 enables the column 211 to disperse and relieve stress through deformation of the slot wall when subjected to pressure or tension, thereby improving the stability of the entire positioning unit 2; when the flange 213 is squeezed, the slot wall is recessed toward the inside of the through slot 2121, thereby improving the installability of the entire positioning unit 2.

[0054] From the perspective of equivalent implementations of the mechanical structure, the design of the avoidance space 212 can adopt a variety of different forms to achieve similar functions. For example, in addition to the through groove, the avoidance space can also be formed by a cavity structure of a hole, a groove or other shapes. These structures can also provide the elasticity and adaptability required by the positioning column while maintaining its structural strength. In the present utility model, there is no limitation on the form design of the avoidance space, and in the design process, a reasonable choice can be made according to actual needs.

[0055] In the solenoid valve assembly, the through slot 2121 is designed to not only penetrate the column 211, but also have two first side walls 21211 arranged opposite to each other in a direction perpendicular to the central axis of the column 211. This structural feature provides additional stability and support for the column 211. The flange 213, as an important part of the positioning column 21, further enhances the connection strength and stability between the positioning column 21 and the installation environment through the external thread structure surrounding the two first side walls 21211.

[0056] From the perspective of equivalent implementation of the mechanical structure, the design of the flange 213 is not limited to the external thread structure. In practical applications, the flange can also adopt a buckle, a bump or other forms of connection structure to achieve a stable connection with the installation environment. These different connection methods can be selected and optimized according to specific application scenarios and requirements to meet the installation and use requirements of different solenoid valve assemblies.

[0057] In some embodiments, the through slot 2121 has two first side walls 21211 arranged opposite to each other in a direction perpendicular to the central axis of the column 211. This structure not only provides necessary support and stability for the positioning column, but also provides a suitable installation position for the flange 213.

[0058] Specifically, the flange 213 is cleverly arranged on one of the two first side walls. Such a design not only saves space but also ensures an effective connection between the positioning column and the installation environment.

[0059] From the perspective of equivalent implementation of the mechanical structure, the position of the flange 213 is not fixed. In practical applications, the flange can be set on any one of the two first side walls according to specific needs and installation environments, or even adopt a symmetrical design distributed on the two side walls to enhance the stability and balance of the connection.

[0060] In addition, the shape and structure of the flange can also be flexibly adjusted according to the actual application, such as using flanges of different heights, flanges with inclined surfaces, etc., to meet the installation and use requirements of different solenoid valve assemblies. This flexibility and diversity makes the technical solution more widely applicable and feasible in practical applications.

[0061] In the solenoid valve assembly, the coil unit 11 includes a coil body 112. The coil body 112 is a core component responsible for generating the necessary electromagnetic field to drive the solenoid valve. The plug 111 is specially designed as a male plug, which enables the coil unit to be easily connected to other electrical components or devices.

[0062] refer to Figure 2 and Figure 4 As best shown, the male plug includes a plug body 1111, a pin 1112, and a guide protective wall 1113 arranged around the pin. The plug body 1111 is electrically connected to the coil body 112 through a connecting wire, ensuring the stable transmission of the electromagnetic signal. The pin 1112 and the guide protective wall 1113 are cleverly arranged at one end of the plug body 1111 away from the coil body. Such a layout not only optimizes space utilization, but also improves the convenience of plugging. The setting of the guide protective wall 1113 can facilitate the plugging and plugging into the socket of the installation equipment on the one hand, and on the other hand, the guide protective wall 1113 can also protect the pin 1112 from being hit by external objects.

[0063] From the perspective of equivalent implementation of the mechanical structure, the design of the guide and protection wall 1113 is not fixed. In practical applications, the shape, size and material of the guide and protection wall can be flexibly adjusted according to specific needs and installation environments. For example, the guide and protection wall can be designed with different heights to accommodate plug-in devices of different sizes; or a design with an inclined surface can be used to facilitate alignment and positioning during plug-in.

[0064] In addition, the number and layout of the pins 1112 can also be flexibly adjusted according to the actual application, such as using multiple pins to achieve a more complex electrical connection, or adjusting the spacing between the pins to adapt to different plug-in devices. This flexibility and diversity makes the coil unit more widely applicable and feasible in practical applications. It can be understood that the pins 1112 are electrically connected to the connecting wires mentioned above.

[0065] Furthermore, in the plug 111 of the solenoid valve assembly, the design of the guide protection wall 1113 is not limited to its basic guiding and protection functions. In order to further enhance the connection stability and convenience between the coil unit and the installation device, we specially set a snap-on structure 11131 on the outer side of the guide protection wall. This ingenious design enables the plug 111 to be firmly fixed on the installation device, effectively preventing it from falling off or loosening due to vibration or external force.

[0066] From the perspective of equivalent implementation of the mechanical structure, the specific form of the buckle structure 11131 is not fixed. In practical applications, the shape, size and position of the buckle structure can be flexibly adjusted according to the specific shape and size of the installation device to achieve a more stable and reliable connection effect. This flexibility and adaptability makes the coil unit more widely applicable and feasible in practical applications.

[0067] In the solenoid valve assembly, the positioning unit 2 includes a mounting seat, the mounting seat 22 is extended along the axial direction of the plug 111, and is tightly connected to the plug 111 through a snap-fit ​​structure. This design ensures that the positioning unit 2 can be firmly mounted on the plug and is easy to disassemble and replace.

[0068] The positioning column 21 is cleverly arranged on the side of the mounting base 22 facing away from the plug. Such a layout not only optimizes space utilization, but also enables the positioning column to more accurately cooperate with the corresponding structure on the mounting device, thereby achieving a more precise positioning effect.

[0069] In practical applications, the specific form of the snap-fit ​​structure can be flexibly adjusted as needed, such as using different designs such as snap-fits and slots to adapt to different installation environments and needs. This flexibility and adaptability makes the positioning unit more widely applicable and feasible in practical applications.

[0070] In this embodiment, the design of the mounting seat 22 fully considers the stable connection with the plug 111. Specifically, the mounting seat 22 has two oppositely arranged side walls, and each side wall is cleverly provided with a clamping strip 221 protruding outward. These clamping strips 221 extend along the axial direction of the plug 111, providing additional stability and fixing force for the mounting seat 22.

[0071] At the same time, a clamping groove 1114 is provided on one side of the plug 111 facing the positioning unit 2, and the mounting seat 22 is just arranged in this groove. In order to further enhance the stability of the connection, a clamping rib 11141 is also provided on the inner side of the groove side wall of the clamping groove 1114 to be clamped with the clamping strip 221. Such a design not only ensures that the mounting seat 22 can be firmly fixed on the plug 111, but also makes the entire positioning unit 2 more compact and reliable.

[0072] In practical applications, the specific shapes and sizes of the clamping strip 221 and the clamping rib 11141 can be flexibly adjusted as needed to adapt to different installation environments and requirements. This arrangement allows the plug 111 to be quickly installed and matched with the positioning unit 2, avoiding the problem of low efficiency when using mounting screws to fix the two.

[0073] In the design of the solenoid valve assembly, a limit member 1115 is also provided on the plug 111. This ingenious design ensures the accuracy and stability of the positioning unit 2 during the installation process. The limit member 1115 can be cleverly arranged on the bottom wall of the snap-in groove 1114, or on the side of the plug 111 facing the positioning unit 2, and is located in the axial extension direction of the bottom wall of the plug 111. Such a layout not only limits the movement range of the positioning unit 2 on the mounting seat 22, but also ensures that the positioning unit can be accurately positioned at a predetermined position. In practical applications, the specific shape, size and position of the limit member 1115 can be flexibly adjusted as needed to adapt to different installation environments and requirements, thereby further enhancing the applicability and reliability of the solenoid valve assembly.

[0074] In the embodiment of the present utility model, the solenoid valve assembly generally further includes a valve body 12 matched with the coil unit 11 , and the coil unit 11 is connected to the valve body 12 .

[0075] In summary, the embodiments of the present invention achieve the following technical effects:

[0076] When the positioning column 21 is inserted into the mounting hole of the mounting device, the flange 213 is squeezed so that the side wall connected to it is recessed toward the avoidance space, thereby facilitating the positioning column 21 to be inserted into the mounting hole. At least two positioning columns 21 distributed along the axial direction of the plug 111 can lock the position of the plug 111 relative to the mounting device, thereby preventing the plug 111 from being inserted crookedly or not inserted into place when mating with the socket due to the plug 111 not being fixed.
