[0032] The connector of the present application includes a connecting pipe for connecting to a pipe of an air conditioner; a connector fixedly mounted to the connecting pipe so that the connecting pipe is in fluid communication with the connector to form a flow path, and the connector has a valve port. The moving component is movably arranged inside the connector via a spring, one end of the spring is fixed to a support plate, and the other end is fixed to the moving component, and the support plate is fixedly mounted to the connecting pipe or the connector, and the moving component can move between a first position and a second position, in the first position, the moving component blocks the valve port, and in the second position, the moving component does not block the valve port. The flow regulating feature is arranged in a portion of the flow path located in the connector, and is configured to regulate the flow of the fluid in the flow path to suppress the noise generated by the fluid.

[0033] The following are respectively Figure 1 and Figure 2 to describe the female and male connectors, although Figure 1 and Figure 2 Different types of connectors are described, but it should be understood that the above applies to both connectors.

[0034] like Figure 1 As shown, the female connector includes a connecting pipe 1, which is used to connect to a pipe (not shown) of an air conditioner. A connector 2 is fixedly mounted to the connecting pipe 1 and is in fluid communication with the connecting pipe 1 to form a flow path in which the fluid can flow. The connector 2 has a valve port 21. Figure 1 In the example of FIG. 4 , a connecting portion 22 of the connector 2 is also shown, which is intended to be connected to a corresponding connecting portion of a female connector, which will be described later.

[0035] In the case of a female connector, the moving part is a valve stem 3 having an axis 31 and a rod head 32, the axis 31 extending through a support plate 4, the other end of a spring 5 being fixed to the rod head, in a first position of the valve stem, the rod head 32 blocking the valve port, and in a second position of the valve stem, the rod head 32 not blocking the valve port.

[0036] The flow regulation feature includes a flow guide 6, one end of which is fixed to the support plate 4, and the other end is free and does not interfere with the movement of the valve stem 3. The spring 5 is sleeved on the flow guide 6, and the flow guide has an internal channel that is in fluid communication with the connecting pipe, allowing the fluid to flow through the connecting pipe and the flow guide, thereby isolating the spring from the fluid. In this way, the fluid from the connecting pipe will flow into the internal channel of the flow guide, so that it will not contact the spring, avoiding the disturbance of the fluid caused by the spring, and suppressing the noise generated when the fluid flows.

[0037] The flow conditioning feature also includes a porous seat 7, in Figure 1 In the embodiment, the porous seat 7 is mounted to the rod head 32 and has a plurality of holes distributed along the circumference, and the plurality of holes are configured to be in fluid communication with the internal channel of the air guide cover. Figure 1 As shown, the porous seat has an opening 71 for accommodating the other end of the spring 5, and the other end of the spring is fixed to the bottom of the opening of the porous seat. Due to the multiple holes of the porous seat, the fluid flows through the multiple holes in a dispersed manner, and the noise generated when the fluid flows is also suppressed.

[0038] In the first position of the valve stem, Figure 1 As shown, the free end of the guide cover is spaced apart from the porous seat; in the second position of the valve stem, as shown Figure 4 As shown, the free end of the air guide cover abuts against the bottom of the opening of the porous seat, and a part of the spring is located between the side wall of the opening of the porous seat and the outer wall of the air guide cover.

[0039] like Figure 2 As shown, the male connector includes a connecting pipe 1', which is used to connect to a pipe (not shown) of an air conditioner. A connector 2' is fixedly mounted to the connecting pipe 1' and is in fluid communication with the connecting pipe 1' to form a flow path in which the fluid can flow. The connector 2' has a valve port 21'. Figure 2 In the example of the embodiment, the connector 2' has a first part 22', a second part 23' and a third part 24', the third part 24' is used to connect to the connecting pipe 1', the second part 23' is used to connect with the connecting part of the female connector (described below), and the first part 22' is connected between the second part 23' and the third part 24'. Generally speaking, the connecting part of the female connector and the second part of the male connector have threads for threaded connection.

[0040] In the case of a male connector, the moving part is a valve core 3 ′, and the male connector has a push rod 5 ′ fixedly mounted to a support plate 4 , and the valve core 3 ′ is arranged around the push rod 5 ′.

[0041] like Figure 2 As shown, the diameter of the second part 23' of the joint is larger than that of the first part 22', the diameter of the valve core 3' is smaller than that of the first part 22', and one part is located in the first part and the other part is located in the second part.

[0042] The push rod 5' has an axis 51' mounted on the support plate 4 and a push head 52' away from the support plate 4. The valve port 21' is formed between the valve core 3' and the push head 52'. In the first position of the valve core, the valve core abuts against the push head to block the valve port. In the second position of the valve core, the valve core is disengaged from the abutment with the push head to release the valve port.

[0043] The flow regulating feature includes a guide cover 6', one end of which is fixed to the support plate 4, and the other end is free and does not interfere with the movement of the valve core 3'. The spring 5 is sleeved on the guide cover 6', and the guide cover has an internal channel that is fluidly connected to the valve port and the connecting pipe.

[0044] The flow regulating feature includes a porous seat 7', which is mounted to the support plate 4 so that the plurality of holes of the porous seat 7' are in fluid communication with the internal passage of the flow guide cover, one end of the spring is supported on the porous seat, and the other end is supported on the valve core 3'. Figure 2 In the case of the male connector shown, the support plate 4 and the porous seat 7' are formed as one piece.

[0045] Figure 3 A cross-sectional view showing the male connector and the female connector when not assembled together, Figure 4 A cross-sectional view showing the male connector and the female connector when assembled together. Figure 4 As shown, the connecting part 22 of the female connector is screwed together with the second part 23' of the male connector, during which the push head 52' of the push rod 5' of the male connector pushes the valve stem 5 of the female connector and moves the valve stem 5 from the first position to the second position to release the valve port 21 of the female connector. At the same time, the connecting part 22 of the female connector has a step 23, which is configured to abut and push the valve core 3' of the male connector when the connecting part 22 of the female connector is connected to the second part of the male connector, so that the valve core 3' moves from the first position to the second position to release the valve port 21' of the male connector. As a result, the flow path of the male connector is fluidically connected to the flow path of the female connector, and the fluid can flow between the male connector and the female connector.
