In some embodiments, two openings of the water inlet 310, the water outlet 320 and the assembling opening 330 are disposed at opposite ends of the guide tube 300, and the other opening is disposed at a side of the guide tube 300, so that the three openings on the guide tube 300 are arranged in three directions to guide the flow direction of the water flow. Based on the wiring requirements of the water pipes in different direct drinking water machines, the water inlet 310 and the water outlet 320 can be arranged at two opposite ends of the guide pipe 300 in a back-to-back manner, and the assembly port 330 is arranged on the side surface of the guide pipe 300, so that the water inlet pipe 100 communicated with the water inlet 310 and the water outlet pipe 200 communicated with the water outlet 320 can be arranged along the same direction, and the linear wiring requirements of the water pipes in the direct drinking water machines are met.

Based on the installation space in different direct drinking machines and the wiring requirements of water conveying pipelines, the water flow direction in the pipeline connecting structure can be planned by designing the structure of the water conveying channel 340. As shown in fig. 2, 3 and 4, in some embodiments, the water delivery passage 340 includes a first passage 341, a connection passage 342 and a second passage 343 which are sequentially communicated, and the first passage 341 is communicated with the first flow passage 110 in the water inlet pipe 100 through the water inlet 310 to guide the direction of the water flow entering the guide pipe 300; the second channel 343 is communicated with the second flow channel 210 in the water outlet pipe 200 through the water outlet 320 to guide the direction of the water flowing out of the guide pipe 300; the connection channel 342 is communicated with the assembly opening 330, the water purification assembly 400 is accommodated in the connection channel 342, and the wall surface of the water purification assembly 400 is attached to the wall surface of the connection channel 342, so that the water flowing into the connection channel 342 through the first channel 341 can completely pass through the filter element 410 of the water purification assembly 400 and then flow out through the second channel 343.

It is also possible to facilitate planning of the installation space occupied by the guide tube 300 by adjusting the flow path lengths of the first passage 341, the connection passage 342, and the second passage 343. For example, the first passage 341 and the second passage 343 may be bent in multiple sections, so that the exterior of the guide tube 300 where the first passage 341 and the second passage 343 are located may avoid other installation components, thereby making the structural design of the guide tube 300 more flexible and facilitating reasonable planning of installation space. In some embodiments, the connection channel 342 is a straight type channel, the water purification assembly 400 is disposed in the connection channel 342, and the straight type connection channel 342 also facilitates installation and removal of the water purification assembly 400, for example, the water purification assembly 400 can be directly inserted into the connection channel 342 in a direction axially parallel to the connection channel 342, or the water purification assembly 400 can be directly removed from the connection channel 342 in a direction axially parallel to the connection channel 342.

In the design of the internal water pipe of the direct water dispenser, based on the different installation positions of the water pipe, as shown in fig. 2 and 3, the first flow channel 110 in the inlet pipe 100 and the second flow channel 210 in the outlet pipe 200 may be arranged in the same direction or in parallel, for example, when the water pipe needs to be arranged near one of the walls of the cabinet of the direct water dispenser, the first flow channel 110 and the second flow channel 210 may be arranged in the same direction. As shown in fig. 4, alternatively, the first flow channel 110 in the water inlet pipe 100 and the second flow channel 210 in the water outlet pipe 200 may be disposed perpendicular to each other or at an included angle, for example, when the water conveying pipeline needs to be installed adjacent to two adjacent walls disposed at a right angle, the first flow channel 110 and the second flow channel 210 may be disposed perpendicular to each other. Specifically, various piping wiring requirements can be satisfied by changing the structure of the water delivery channel 340 in the guide tube 300 connected to the first flow channel 110 and the second flow channel 210.

When the first flow channel 110 and the second flow channel 210 are disposed perpendicular to or at an angle with respect to each other, as shown in fig. 4, in some embodiments, the first channel 341 is disposed coaxially with the first flow channel 110 in the inlet pipe 100, the first channel 341 is disposed axially perpendicular to or at an angle with respect to the connecting channel 342, and the second channel 343, the connecting channel 342 are disposed coaxially with the second flow channel 210 in the outlet pipe 200, so that the inlet 310, the outlet 320, and the fitting 330 face three different directions without interfering with each other.
