[0048] In the description of the present application, it should be noted that unless otherwise explicitly specified and limited, the terms "mounting", "connecting", "connecting" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0049] In people's daily life, household appliances often need to combine two pipes 1 together and then fix them on other parts, or need to fix a single pipe 1 on other parts.

[0050] For example, for a water heater, it usually includes a water tank, which includes an inner container and an outer shell, a pipe 1 is arranged between the inner container and the outer shell, the pipe 1 at least includes a water inlet pipe and a water outlet pipe, one end of the water inlet pipe and the water outlet pipe is communicated with the inner container respectively, and the other end protrudes from the outer shell and is provided with a water inlet connector and a water outlet connector respectively, so as to be connected with the water circuit outside the water heater.

[0051] In this case, the connectors at the ends of the water inlet pipe and the water outlet pipe are usually fixed by injection molding with plastic at the same time, or the connectors of the water inlet pipe and the water outlet pipe are fixed by injection molding with plastic respectively, and then the injection molding part is fixed and installed on the outer shell, so that the connectors of the two water pipes are fixed on the outer shell and can be connected with the water circuit outside.
