A first connection port 111 is provided on the bottom surface of the joint outer shell 11, and at least one second connection port 112 is provided on the side wall of the joint outer shell 11. The first connection port 111 and the second connection port 112 are respectively connected to different components, and the joint outer shell 11 plays a role of switching. The axis of the first connection port 111 is perpendicular to the axis of the second connection port 112.
[0039] An upper opening 113 is provided on the top surface of the joint outer shell 11, and the upper opening 113, the first connection port 111, and the second connection port 112 are all connected to the inner cavity of the joint outer shell 11. When the inner core 12 is connected to the upper opening 113 and seals the upper opening 113, the first connection port 111 is connected to the second connection port 112 through the inner cavity, so that the fluid can flow out from the second connection port 112 after flowing into the inner cavity of the joint outer shell 11 from the first connection port 111, so that the pipe joint can achieve the function of fluid communication.
[0040] It should be noted that the joint outer shell 11 and the inner core 12 can be welded or detachably connected, as long as the inner core 12 is firmly connected to the joint outer shell 11 and the inner core 12 can seal the upper opening 113 .
[0041] When the pipe joint of this embodiment is used, the first connection port 111 and the second connection port 112 of the joint outer shell 11 can be welded to different components respectively. During welding, since the joint outer shell 11 is provided with an upper opening 113, the upper opening provides convenience for inserting a welding gun into the joint outer shell 11 for welding, making the welding method more flexible, and the welding sequence can be adjusted as needed, thereby making the welding operation more convenient and ensuring the sealing performance of the welding point. After the welding of the joint outer shell 11 and the external component is completed, the inner core 12 is covered at the upper opening 113 and the upper opening 113 is sealed to ensure the airtightness of the pipe joint.
[0042] The pipe joint of this embodiment can simplify the pipe joint welding process, improve the yield rate, and is more conducive to mass production.

The joint outer shell 11 is in a cube shape. The bottom end of the inner core 12 abuts against the bottom surface of the inner cavity of the joint outer shell 11, so that the inner core 12 is more convenient to position when connected to the joint outer shell 11, making the connection more secure.
[0046] In addition, a fool-proof mark is provided on the outer side of the inner core 12. The fool-proof mark can be a pattern or a prominent color mark, which facilitates the alignment of the first connection port 111 with the first inner opening 121 and the second connection port with the corresponding second inner opening 122, thereby improving the connection efficiency.

The axes of the two second connection ports 112 are on the same straight line.
[0048] The two second connection ports 112 can be connected to two different components respectively, and in this case the pipe joint realizes the function of a tee.
[0049] As a preferred embodiment, three second connection ports 112 are provided, and the three second connection ports 112 are respectively provided on three sides of the joint outer shell 11. Second inner openings 122 are provided on the three side walls of the inner core 12, and the three second connection ports 112 are all connected to the first connection port 111. The axes of two second connection ports 112 are on the same straight line, and the axis of another second connection port 112 is perpendicular to the straight line.
[0050] The three second connection ports 112 can be connected to three different components respectively, and in this case the pipe joint can achieve a four-way function.
[0051] As a preferred embodiment, four second connection ports 112 are provided, and the four second connection ports 112 are respectively provided on the four sides of the joint outer shell 11. Second inner openings 122 are provided on the four side walls of the inner core 12, and the four second connection ports 112 are connected to the first connection port 111.

[0052] The four second connection ports 112 can be connected to four different components respectively, and in this case the pipe joint realizes the function of a five-way connection.

Alternatively, the first connection port 111 of the joint outer shell 11 can be welded to the container, and then the second connection port 112 of the joint outer shell 11 is welded to the pipe.
[0061] As a preferred embodiment, when the first connection port 111 of the joint outer shell 11 is welded to the first component 3 , the welding gun head passes through the inner cavity from the upper opening 113 of the joint outer shell 11 to the first connection port 111 .
[0062] When the first connection port 111 of the joint outer shell 11 is welded to the container, a welding gun can be inserted into the inner cavity of the joint outer shell 11 to weld the first connection port 111 to the container, thereby facilitating the welding operation.
