Description

Technical Field

[0001] This utility model relates to the field of coffee machine technology, and in particular to a self-sealing water pipe structure and a coffee machine. Background Technology

[0002] When connecting an external water tank to a coffee machine, a flexible hose (water pipe) is usually used to connect it to the tank. This hose is usually straight. When the hose is disconnected from either the machine or the water tank, the water inside the hose will naturally flow out. Especially when only the machine end is disconnected, due to the siphon effect, the water in the tank will flow out along the hose from the lower connector. This situation greatly affects the user experience.

[0003] Therefore, further improvements are necessary. Utility Model Content

[0004] The purpose of this utility model is to provide a water pipe self-sealing structure and coffee machine that is simple in structure, has good sealing effect, is stable and reliable, has a good user experience, and is highly practical, so as to overcome the shortcomings of the prior art.

[0005] A self-sealing water pipe structure designed for this purpose includes a water pipe and a connector for connecting a water pipe joint. The connectors are respectively located at both ends of the water pipe. The connector is characterized by having a flow channel inside, one end of which connects to the water pipe, and the other end of which is closed. A bypass hole is provided on one side of the flow channel. A first sealing element is movably disposed on the connector. When the first sealing element moves, it opens or closes the bypass hole. When the connector is inserted into the water pipe joint, the water pipe joint acts on the first sealing element, causing the first sealing element to move to a first position, thereby opening the bypass hole, and the flow channel connects to the water pipe joint through the bypass hole. When the connector is separated from the water pipe joint, the water pipe joint acts on the first sealing element, causing the first sealing element to move to a second position, thereby closing the bypass hole.

[0006] One end of the connector is connected to a water pipe, and the other end is provided with a movable groove. The first sealing element is movably positioned on the movable groove, and the bypass hole is located on one side of the movable groove.

[0007] The connector head is provided with a plug-in part, and the water pipe connector is provided with a plug-in hole. The plug-in part and the plug-in hole are plugged into each other, and the movable groove is provided on the plug-in part; when the first seal opens the bypass hole, the flow channel is connected to the plug-in hole through the bypass hole.

[0008] The first seal has a protrusion on its outer side, which at least partially protrudes from the movable groove. The protrusion is press-fitted with the wall of the insertion hole. When the connector is inserted into or separated from the water pipe connector, the wall of the insertion hole acts on the protrusion to make the first seal move in the movable groove.

[0009] When the connector is inserted into or separated from the water pipe joint, the movement direction of the connector is opposite to that of the first seal.

[0010] The other end of the connector is provided with a sealing part, which seals the other end of the flow channel. When the first seal moves to the second position, it is located on the sealing part.

[0011] A limiting part is provided on the connector head, and the first seal is positioned on the limiting part when it moves to the first position.

[0012] A sealing groove is provided on the plug part, and a second sealing element is provided on the sealing groove. The second sealing element is in clearance fit with the wall of the plug hole.

[0013] One end of the connector is provided with a connecting part, which is inserted into the water pipe, and the flow channel runs through one end of the connector.

[0014] A coffee machine designed for this purpose includes a coffee machine body and a water tank, characterized in that: it also includes the aforementioned self-sealing water pipe structure, and water pipe connectors are respectively provided on the coffee machine body and the water tank. The two ends of the water pipe are respectively connected to the corresponding water pipe connectors through connectors, thereby connecting the coffee machine body and the water tank.

[0015] This utility model's self-sealing water pipe structure features a first sealing element movable on the connector and a bypass hole on one side of the flow channel. When the connector is inserted into the water pipe joint, the first sealing element slides to a first position due to friction. After the position of the first sealing element changes, the bypass hole covered by it can connect to the outside, forming a passage with the pipeline. When the connector is pulled out from the water pipe joint, the first sealing element slides to a second position due to friction, covering the bypass hole and preventing water from flowing out of the pipe. The structures at both ends of the water pipe are identical, so pulling out either end or both ends together will seal the pipe and prevent water from flowing out. When both ends are inserted simultaneously, the pipeline can be opened. This also prevents water in the tank from flowing out of the lower connector along the water pipe due to siphon effect when only the machine end is pulled out, effectively improving the user experience.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] See Figures 1-7 This self-sealing water pipe structure includes a water pipe 1 and a connector 2 for connecting to a water pipe connector 3. Connectors 2 are located at both ends of the water pipe 1. A flow channel 4, which is a blind hole, is provided in the middle of the connector 2. One end of the flow channel 4 connects to the water pipe 1, and the other end is closed. A bypass hole 5 is provided on one side of the flow channel 4. A first sealing element 6, which is a sealing ring, is movably mounted on the connector 2. When the first sealing element 6 moves, it opens or closes the bypass hole 5. When the connector 2 is inserted into the water pipe connector 3 (i.e., when...), the water pipe connector 3... When connector 2 is inserted into water pipe connector 3, water pipe connector 3 acts on the first seal 6 to move the first seal 6 to the first position A, thereby opening the bypass hole 5, and the flow channel 4 connects to water pipe connector 3 through the bypass hole 5; when connector 2 is separated from water pipe connector 3 (i.e. when connector 2 is pulled out from water pipe connector 3), water pipe connector 3 acts on the first seal 6 to move the first seal 6 to the second position B, thereby closing the bypass hole 5, at which time the flow channel 4 is not connected to water pipe connector 3.

[0025] One end of the connector 2 is connected to the water pipe 1, and the other end is provided with a movable groove 7. The first sealing element 6 is movably and limitly disposed on the movable groove 7, and the bypass hole 5 is disposed on one side of the movable groove 7.

[0026] The connector 2 is provided with a plug part 8, and the water pipe connector 3 is provided with a plug hole 9. The plug part 8 and the plug hole 9 are plugged into each other, thereby connecting the connector 2 to the water pipe connector 3. The movable groove 7 and the bypass hole 5 are provided on the plug part 8. When the first seal 6 opens the bypass hole 5, the flow channel 4 connects to the plug hole 9 through the bypass hole 5.

[0027] The first sealing element 6 has a protrusion 10 on its outer side. The protrusion 10 protrudes at least partially from the movable groove 7. The protrusion 10 is interference-fitted with the wall of the insertion hole 9, so that the insertion part 8 and the insertion hole 9 can be tightly inserted into each other, and the gap between the connector 2 and the water pipe connector 3 can be sealed. When the connector 2 and the water pipe connector 3 are inserted or separated, the wall of the insertion hole 9 acts on the protrusion 10, that is, the wall of the insertion hole 9 and the protrusion 10 form friction against each other, so that the first sealing element 6 can move on the movable groove 7.

[0028] When connector 2 is inserted into or separated from water pipe connector 3, the movement direction of connector 2 is opposite to that of the first sealing element 6; for example, Figures 1-4 As shown, connector 2 is inserted downward into water pipe connector 3, first seal 6 moves upward to first position A, connector 2 is pulled upward from water pipe connector 3, and first seal 6 moves downward to second position B.

[0029] The other end of the connector 2 is provided with a sealing part 11, which seals the other end of the flow channel 4. When the first seal 6 moves to the second position B, it is located on the sealing part 11.

[0030] A limiting part 12 is provided on the connector 2, and the first seal 6 is located on the limiting part 12 when it moves to the first position A.

[0031] The limiting part 12 and the first position A are located at one end of the movable groove 7, and the closing part 11 and the second position B are located at the other end of the movable groove 7.

[0032] A sealing groove 13 is provided on the insertion part 8, and a second sealing element 14 is provided on the sealing groove 13. The second sealing element 14 is clearance-fitted with the hole wall of the insertion hole 9, and the second sealing element 14 is a sealing ring.

[0033] One end of the connector 2 is provided with a connecting part 15, which is inserted into the water pipe 1. The flow channel 4 passes through one end of the connector 2, and the water pipe 1 is a flexible hose.

[0034] This coffee machine includes a coffee machine body 16, a water tank 17, and a self-sealing water pipe structure. The coffee machine body 16 and the water tank 17 are respectively provided with water pipe connectors 3. The two ends of the water pipe 1 are respectively connected to the corresponding water pipe connectors 3 through connectors 2, thereby connecting the coffee machine body 16 and the water tank 17.

[0035] The water tank 17 has a top cover 18 with a water outlet and a water pipe connector 3. The water tank 17 has an outlet pipe 19 inside, which is connected to the insertion hole 9. When the bypass hole 5 is open, it connects to the outside and forms a passage with the outlet pipe 19, allowing water in the water tank 17 to flow into the water pipe 1. Similarly, the coffee machine body 16 has a water inlet with a water pipe connector 3 located at the bottom height of the water tank 17. The coffee machine body 16 has an inlet pipe inside, which is connected to the insertion hole 9. When the bypass hole 5 is open, it connects to the outside and forms a passage with the inlet pipe, allowing water in the water pipe 1 to flow into the coffee machine body 16, thus supplying water to the coffee machine.
