Specifically, the heating pipes 22 are uniformly wrapped on both sides of the water pipe 21, so that heat can be uniformly transmitted to the entire water pipe 21, avoiding the problem of local overheating or uneven heating that may occur in the traditional structure. In addition, this structure also helps to prolong the service life of the heating pipes 22 and the water pipe 21, and improves the reliability and durability of the entire coffee machine heating pipe assembly 2. In addition, the heating wires are arranged inside the heating pipes 22, and when the current passes, heat will be generated due to the resistance effect, thereby heating the heating pipes 22 and the water in the water pipe 21 in contact with them, to ensure that heat can be uniformly and efficiently transmitted to the water in the water pipe 21, achieving the purpose of rapid heating.

[0030] Further, the connecting piece 3 is provided with a first annular piece 31 and a second annular piece 32, and the first annular piece 31 is provided with a sealing ring hole 33 for plug-in connection of the water pipe 21.

[0031] In the embodiment, when the water pipe 21 is inserted into the sealing ring hole 33, the sealing ring in the sealing ring hole 33 is tightly attached to the outer wall of the water pipe 21, thereby effectively preventing water from leaking from the connection and enhancing the stability of the connection.

[0032] Further, the first annular member 31 is internally provided with a first sealing rib 36, which is tightly connected to the water pipe 21 to form an interference fit between the water pipe 21 and the first annular member 31.

[0033] In the embodiment, the first sealing rib 36 is tightly connected to the outer surface of the water pipe 21 to form an interference fit, thereby ensuring the stable connection between the water pipe 21 and the first annular member 31 and effectively preventing water from leaking from the connection through the sealing effect of the first sealing rib 36, ensuring the normal operation of the coffee machine and the safety of the user's water use.

[0034] Further, the water inlet connector 5 is provided with a first plug-in part, the water outlet connector 4 is provided with a second plug-in part, the first annular member 31 and the second annular member 32 are provided with a groove 34, and the groove 34 is respectively plug-in connected with the first plug-in part and the second plug-in part.

[0035] Specifically, the first plug-in part of the water inlet connector 5 is inserted into the groove 34, and the second plug-in part of the water outlet connector 4 is inserted into the groove 34, which is tightly connected with the connecting member 3, so that the connecting member 3 is more firmly connected with the water inlet connector 5 and the water outlet connector 4, and the assembly steps are greatly simplified and the assembly efficiency is improved.

[0036] Further, the first annular member 31 is externally provided with a second sealing rib 35, which is tightly connected with the first plug-in part and the second plug-in part, respectively, and when the first plug-in part of the water inlet connector 5 and the second plug-in part of the water outlet connector 4 are inserted into the pre-set groove 34, the second sealing rib 35 can enhance the physical connection between the plug-in part and the groove 34, so that the water inlet connector 5 and the water outlet connector 4 form an interference fit with the first annular member 31, thereby effectively preventing liquid from leaking.

[0037] Further, the first annular member 31 is provided with a first annular boss, the water inlet connector 5 is internally provided with a first abutting boss, the water outlet connector 4 is internally provided with a second abutting boss, the first abutting boss and the second abutting boss are respectively abutted with the outer end surface of the first annular boss, and the water pipe 21 is abutted with the inner end surface of the first annular boss.

[0038] In the embodiment, when the plug-in part of the water inlet joint 5 is connected with the groove 34, the outer end face of the first annular boss is in abutment with the first abutment boss, further ensuring the stable connection of the water inlet joint 5 with the connecting piece 3, so that no leakage occurs when the water inlet of the water inlet joint 5 delivers water flow to the water pipe 21. Similarly, when the plug-in part of the water outlet joint 4 is connected with the groove 34, the outer end face of the first annular boss is in abutment with the second abutment boss, further ensuring the stable connection of the water outlet joint 4 with the connecting piece 3, so that no leakage occurs when the water pipe 21 delivers water flow to the water outlet of the water outlet joint 4.

[0039] In the embodiment, the water pipe 21 is cylindrical, and the diameters of the two ends of the water pipe 21 are smaller than the diameter of the middle part of the water pipe 21. The end faces of the two ends of the water pipe 21 are stepped. When the water pipe 21 is connected with the first annular piece 31, the end face of the water pipe 21 is in abutment with the inner end face of the first annular boss, which plays a role of blocking heat and prevents the end face of the water pipe 21 from directly contacting the water inlet joint 5 and the water outlet joint 4, thereby ensuring the stable connection of the water outlet joint 4 with the connecting piece 3. Moreover, the stepped end faces of the two ends of the water pipe 21 make it easier to realize alignment and insertion when the water pipe 21 is inserted into the first annular piece 31.

[0040] Further, the first annular piece 31 and the second annular piece 32 are integrally formed, thereby reducing the number of components required in the assembly process and simplifying the assembly process. In the embodiment, the connecting piece 3 is a silica gel sealing ring.
