Description

CROSS-REFERENCE TO RELATED APPLICATIONS This application is a continuation of international patent application No. PCT/CN2022/074848, filed on Jan. 28, 2022, which itself claims priority to Chinese patent application No. 202120593934.6, filed on Mar. 23, 2021, titled “ELECTROMAGNETIC VALVE AND ELECTROMAGNETIC VALVE ASSEMBLY”, which is hereby incorporated by reference. TECHNICAL FIELD The present disclosure relates to a field of a valve device, and in particular, to an electromagnetic valve and an electromagnetic valve assembly. BACKGROUND An electromagnetic valve has a complex structure and cannot be quickly assembled with air conditioning pipelines or other module components, so that mounting efficiency is low. In addition, a spring is provided between a bottom of a valve body and a plugging assembly, and the plugging assembly is driven by an elastic force of the spring to open the valve port, so that the valve is opened. However, the spring in the related art is integrated with the valve body in a riveting form, which can cause the following problems such as a complicated assembly process of the spring, inability to disassemble the spring in the later stage, improved processing difficulty and increased manufacturing costs of the valve body. In the related art, an additional limiting member can be provided to limit the spring. However, the additional limiting member also increases assembly steps of the electromagnetic valve. Moreover, the limiting member may move relative to the valve body during an operation of the electromagnetic valve, resulting in limitation of the spring is not stable enough, which is a hidden danger. SUMMARY For solving the above problem, it is necessary to provide an electromagnetic valve and an electromagnetic valve assembly. To achieve the above objectives, technical solutions provided by the present disclosure are as follows. The electromagnetic valve includes a valve body and a plugging assembly. The valve body is provided with a first mounting cavity and a valve port. The plugging assembly is accommodated in the first mounting cavity for opening or closing the valve port. The electromagnetic valve further includes a first elastic member, an end of the first mounting cavity proximal to the valve port is provided with a limiting portion integrated with the valve body, and the first elastic member is sleeved on the plugging assembly. One end of the first elastic member abuts against the plugging assembly, the other end of the first elastic member abuts against the valve body, and an outer surface of the other end of the first elastic member abuts against the limiting portion. It is understood that when an end of the first elastic member away from the plugging assembly is not limited, an offset or a side bend of the first elastic member can be generated when the first elastic member moves back and forth along an axis of the valve body. In this way, the first elastic member cannot always move linearly along the axis of the valve body, resulting in an offset of a direction of a driving force applied on the plugging assembly by the first elastic member, thereby affecting sealing effect of the plugging assembly on the valve port. In the present disclosure, the limiting portion can be provided to limit and position the first elastic member, thus preventing the first elastic member from offsetting or side bending caused by moving along a radial direction of a cross section of the first elastic member and ensuring that the first elastic member moves linearly along the axis of the valve body. In addition, a friction force can be applied on the other end of the first elastic member by the limiting portion, which is conducive to preventing the other end of the first elastic member from entangling with a middle part of the first elastic member during reciprocating compression and extension of the first elastic member. Furthermore, in the present disclosure, the limiting portion is integrated with the valve body, thus preventing increasing assembly steps of the electromagnetic valve, which is conducive to improving overall assembly efficiency of the electromagnetic valve. In addition, the limiting portion can be avoided to move relative to the valve body during operation, thus affecting limiting effect of the first elastic member. In some embodiments, the limiting portion is a protrusion disposed in the first mounting cavity and extending along an axial direction of the plugging assembly and the outer surface of the first elastic member abuts against a side surface of the protrusion. It is understood that the limiting portion can be a protrusion and the protrusion can be simple in structure, thus reducing difficulty of processing the valve body. In some embodiments, a bottom of the first mounting cavity at an end of the first mounting cavity proximal to the valve port is concave and defined as a limiting groove, and a groove surface of the limiting groove is defined as the limiting portion.
