[0070] In an alternative embodiment, the moving component includes: an intermediate shaft 17, a first push plate 171 and a second push plate 172; the intermediate shaft 17 is disposed through the joint body 1, and the intermediate shaft 17 is arranged along the axis of the joint body 1; the intermediate shaft 17 passes through the first ring body 11, the second ring body 12, the third ring body 13, the first moving plate 15 and the second moving plate 16; the first push plate 171 and the second push plate 172 are disposed on the intermediate shaft 17; there is a space between the inner walls of the first ring body 11, the second ring body 12 and the third ring body 13 and the outer wall of the intermediate shaft 17; the first push plate 171 is disposed between the first moving plate 15 and the second moving plate 16; the second push plate 172 is disposed on the side of the second moving plate 16 away from the first moving plate 15; the distance between the first push plate 171 and the first moving plate 15 is greater than the distance between the second push plate 172 and the second moving plate 16; the first push plate 171 and the second push plate 172 are fixedly connected to the intermediate shaft 17; the intermediate shaft 17 is slidably connected to the first moving plate 15 and the second moving plate 16, and the first moving plate 15 and the second moving plate 16 are in contact with the intermediate shaft 17 to prevent liquid from flowing between the first moving plate 15 and the intermediate shaft 17 and between the second moving plate 16 and the intermediate shaft 17. When the intermediate shaft 17 moves, the intermediate shaft 17 will not drive the first moving plate 15 and the second moving plate 16 to move. When the pipeline is not sleeved on the joint body 1, the first spring 151 is in a compressed state, and the first spring 151 pushes the first moving plate 15 to closely contact the first ring body 11. The second spring 161 is in a compressed state, and the second spring 161 pushes the second moving plate 16 to closely contact the third ring body 13. At this time, if the intermediate shaft 17 starts to move, the intermediate shaft 17 will not drive the first moving plate 15 and the second moving plate 16 to move; during the movement of the intermediate shaft 17, the first moving plate 15 and the second moving plate 16 can play a role of guiding and limiting, so that the intermediate shaft 17 will not deviate during movement.

[0071] In an alternative embodiment, the diameter of the first push plate 171 is smaller than the inner diameter of the first ring body 11, which facilitates the first push plate 171 to pass through the first ring body 11 and contact the first moving plate 15; the diameter of the second push plate 172 is smaller than the inner diameter of the third ring body 13, which facilitates the second push plate 172 to pass through the third ring body 13 and contact the second push plate 172.

[0072] In an alternative embodiment, the adjusting assembly includes: an insertion block 18; a part of the insertion block 18 is inserted into a receiving groove 19 formed at the bottom of the inner wall of the joint body 1, and a part of the insertion block 18 extends out of the receiving groove 19 and is located inside the joint body 1; a through groove 181 is formed on the top surface of the part of the insertion block 18 extending into the joint body 1, and the bottom of the second moving plate 16 is located in the through groove 181; the receiving groove 19 communicates with the inside of the joint body 1 through a communication hole; a groove 131 is formed at a position near the bottom of the side of the third ring body 13 facing the second ring body 12, and the groove 131 extends to the side wall of the receiving groove 19; when the joint body 1 is horizontally arranged, a receiving groove 19 is formed at the bottom of the inner wall of the joint body 1, and the receiving groove 19 extends into the side wall of the joint body 1, that is, a part of the receiving groove 19 is located in the wall thickness of the inner wall of the joint body 1, and a part is open at the bottom of the inner wall of the joint body 1, and the insertion block 18 is inserted into the receiving groove 19; when the second moving plate 16 moves, the insertion block 18 can be driven to move through the through groove 181; in the initial state, the volume of the insertion block 18 extending into the receiving groove 19 is small, and at this time, the receiving groove 19 can accommodate more liquid; the insertion block 18 can extend into the groove 131 so that the second moving plate 16 can be in close contact with the third ring body 13.

[0073] In an alternative embodiment, a snap ring 191 is provided on the outer wall of the joint body 1, a ring groove 192 is formed on the side of the snap ring 191 away from the smaller end face of the joint body 1, a snap block can be provided on the inner wall of the pipeline, and when the pipeline is sleeved outside the joint body 1, the snap block will pass over the snap ring 191 and then be inserted into the ring groove 192.

[0074] In an alternative embodiment, a spring can be provided at one end of the intermediate shaft 17 close to the limit ring 14, the spring can be connected to the inside of the pump housing 2, and the flow channel in the housing 2 connecting the liquid inlet and the liquid outlet can meet the movement requirements of the intermediate shaft 17, that is, the intermediate shaft 17 can extend into the flow channel to meet the movement requirements, and the spring of the intermediate shaft 17 can be connected to the inner wall of the flow channel.

[0075] In the initial state, that is, when the pipeline is not sleeved on the joint body 1, the first moving plate 15 is in close contact with the first ring body 11, and the second moving plate 16 is in close contact with the third ring body 13. At this time, when the pipeline is sleeved outside the joint body 1, the shaft body provided in the pipeline is aligned with and contacts the intermediate shaft 17, and when the pipeline is sleeved, the shaft body will drive the intermediate shaft 17 to move (for example, in Figure 2When the middle shaft 17 moves leftward, the movement of the middle shaft 17 drives the first push plate 171 and the second push plate 172 to move. The second push plate 172 will first contact the second moving plate 16, causing the second moving plate 16 to disengage from the third ring body 13. After the second push plate 172 pushes the second moving plate 16 to move a certain distance, the first push plate 171 contacts the first moving plate 15, and the first push plate 171 pushes the first moving plate 15 away from the first ring body 11, causing the joint body 1 to be opened. After the pipeline is sleeved, the clamping block on the inner wall of the pipeline will insert into the annular groove 192. At this time, the spring on the middle shaft 17 will push the middle shaft 17 to move rightward, making the annular groove 192 and the clamping block contact more tightly, so that the pipeline can be fixed more firmly. When the fixed shaft moves leftward, it will drive the insertion block 18 to insert into the receiving groove 19, and squeeze the liquid in the receiving groove 19 out of the communication hole, facilitating the receiving groove 19 to receive liquid again. When disassembling the pipeline, the spring causes the middle shaft 17 to reset, the first spring 151 causes the first moving plate 15 to reset, and the second spring 161 causes the second moving plate 16 to reset. The first moving plate 15 will first contact the first ring body 11, causing the connection between the joint body 1 and the flow channel in the pump to be closed first, avoiding the liquid in the flow channel of the pump from flowing into the joint body 1. The reset of the middle shaft 17 causes the part of the insertion block 18 extending into the receiving groove 19 driven by the second moving plate 16 to decrease, and the space in the receiving groove 19 that can hold liquid increases. The liquid remaining in the first moving plate 15 and the second moving plate 16 will flow into the receiving groove 19, and more liquid can be held, avoiding the liquid in the joint body 1 from flowing out. After the second moving plate 16 contacts the third ring body 13, the joint body 1 is closed. The space between the third moving plate and the step can be used to hold the liquid remaining in the space on the right side of the second moving plate 16 in the joint body 1, better avoiding the liquid in the joint body 1 from flowing out.

[0077] In an alternative embodiment, a flow channel is provided in the housing 2 to communicate the liquid inlet and the liquid outlet.

[0078] In at least one other publicly disclosed embodiment, a method of using the above-mentioned pump connector is further provided, including: when the pipeline is unplugged from the joint body 1, the valve mechanism is adapted to close the joint body 1.

[0079] In summary, the connector for the pump includes: a connector body 1 and a valve mechanism disposed inside the connector body 1; the connector body 1 is adapted to connect to a pipeline, and when the pipeline is unplugged from the connector body 1, the valve mechanism is adapted to close the connector body 1; it is realized that when the pipeline is removed, the liquid in the connector is prevented from leaking, and the leaked liquid is prevented from damaging the electronic devices.
