The second spring 161 is in a compressed state, and the second spring 161 pushes the second movable 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 movable plate 15 and the second movable plate 16 to move; during the movement of the intermediate shaft 17, the first movable plate 15 and the second movable plate 16 can play a guiding and limiting role, so that the intermediate shaft 17 will not deviate when it moves.

[0033] In an optional embodiment, the diameter of the first push plate 171 is smaller than the inner diameter of the first ring body 11, so that the first push plate 171 can pass through the first ring body 11 to contact the first movable plate 15; the diameter of the second push plate 172 is smaller than the inner diameter of the third ring body 13, so that the second push plate 172 can pass through the third ring body 13 to contact the second push plate 172.

[0035] In an optional embodiment, a clamping ring 191 is provided on the outer wall of the connector body 1, and an annular groove 192 is provided on the surface of the clamping ring 191 away from the smaller end surface of the connector body 1. A clamping block can be provided on the inner wall of the pipe. When the pipe is sleeved outside the connector body 1, the clamping block will pass over the clamping ring 191 and be inserted into the annular groove 192.

[0036] In an optional embodiment, a spring can be provided on one end of the intermediate shaft 17 close to the limit ring 14, and the spring can be connected to the inside of the pump housing 2.

At this time, the pipe is sleeved outside the joint body 1, and the shaft body set in the pipe is aligned with and contacts the intermediate shaft 17. When the pipe is sleeved, the shaft body will drive the intermediate shaft 17 to move (for example, Figure 2The intermediate shaft 17 moves to the left), the movement of the intermediate shaft 17 drives the first push plate 171 and the second push plate 172 to move, and the second push plate 172 will first contact the second moving plate 16, so that the second moving plate 16 is separated from the third ring body 13, and the second push plate 172 pushes the second moving plate 16 to move a certain distance, and then 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, so that the joint body 1 is opened, and after the pipe sleeve is completed, the block on the inner wall of the pipe will be inserted into the annular groove 192. At this time, the spring on the intermediate shaft 17 will push the intermediate shaft 17 to move to the right, so that the annular groove 192 and the block are more closely contacted, so that the pipe can be fixed more firmly, and when the fixed shaft moves to the left, it will drive the plug 18 to insert into the receiving groove 19, and squeeze the liquid in the receiving groove 19 out of the connecting hole, so that the receiving groove 19 can accommodate the liquid again. , the spring resets the intermediate shaft 17, the first spring 151 resets the first movable plate 15, and the second spring 161 resets the second movable plate 16. The first movable plate 15 will first contact the first ring body 11, so that the connection between the joint body 1 and the flow channel in the pump is closed first, preventing the liquid in the flow channel of the pump from flowing into the joint body 1. The reset of the intermediate shaft 17 will cause the second movable plate 16 to drive the part of the plug 18 extending into the receiving groove 19 to decrease, and the space that the receiving groove 19 can accommodate liquid is increased. The residual liquid in the first movable plate 15 and the second movable plate 16 will flow into the receiving groove 19, which can accommodate more liquid and prevent the liquid in the joint body 1 from flowing out. After the second movable plate 16 contacts the third ring body 13, the joint body 1 is closed. The space between the third movable plate and the step can be used to accommodate the residual liquid remaining in the space to the right of the second movable plate 16 in the joint body 1, so as to better prevent the liquid in the joint body 1 from flowing out.

[0039] In an optional embodiment, a flow channel is provided in the housing 2 so that the liquid inlet and the liquid outlet are in communication.

[0040] At least one other disclosed embodiment further provides a method of using the above-mentioned pump connector, including: when the connector body 1 is unplugged from the pipeline, the valve mechanism is suitable for closing the connector body 1.

[0041] In summary, the pump connector includes: a connector body 1, and a valve mechanism arranged inside the connector body 1; the connector body 1 is suitable for connecting a pipeline, and when the pipeline is unplugged from the connector body 1, the valve mechanism is suitable for closing the connector body 1; this achieves the purpose of avoiding leakage of liquid in the connector when the pipeline is removed, and avoiding damage to electronic devices caused by the leaked liquid.
