Abstract

A joint structure configured for a pull-out tube, a pull-out tube structure, and a faucet. The joint structure includes a joint body, two connecting heads respectively disposed on two ends of the joint body, a magnetic component, and an embedded member. The two connecting heads are configured to be connected to the pull-out tube. The magnetic component is sleeved on an outside of the joint body by a first insert molding process, and an outside of the magnetic component is partially encased in the joint body. The magnetic component is partially exposed outside the joint body to form an exposed space, and the embedded member is molded on the exposed space by a second insert molding process. The joint body and the embedded member are combined to encase the magnetic component.

Claims (51)

1 . A joint structure configured for a pull-out tube, comprising:

a joint body,

two connecting heads respectively disposed on two ends of the joint body,

a magnetic component, and

an embedded member, wherein:

the two connecting heads are configured to be connected to the pull-out tube,

the magnetic component is sleeved on an outside of the joint body by a first insert molding process,

an outside of the magnetic component is partially encased in the joint body,

the magnetic component is partially exposed outside the joint body to form an exposed space,

the embedded member is molded on the exposed space by a second insert molding process, and

the joint body and the embedded member are combined to encase the magnetic component.

2 . The joint structure configured for the pull-out tube according to claim 1 , wherein:

a part of the joint body encasing the outside of the magnetic component comprises a first connecting flange and a plurality of first encasing walls,

the first connecting flange is formed on one end of the magnetic component along an axial direction of the joint structure,

the plurality of first encasing walls encase an outer wall of the magnetic component,

one end of the plurality of first encasing walls is connected to the first connecting flange,

the plurality of first encasing walls are arranged at intervals along a circumferential direction of the magnetic component, and

gaps between two adjacent first encasing walls of the plurality of first encasing walls form the exposed space.

3 . The joint structure configured for the pull-out tube according to claim 2 , wherein:

the embedded member comprises a second connecting flange and a plurality of second encasing walls,

the second connecting flange is formed on a second end of the magnetic component in the axial direction of the joint structure,

the plurality of second encasing walls encase the outer wall of the magnetic component,

one end of the plurality of second encasing walls is connected to the second connecting flange,

the plurality of second encasing walls are formed between the two adjacent first encasing walls of the plurality of first encasing walls to be fixedly connected to the plurality of first encasing walls.

4 . The joint structure configured for the pull-out tube according to claim 3 , wherein:

an outer wall of the plurality of first encasing walls is flush with an outer wall of the plurality of second encasing walls.

5 . The joint structure configured for the pull-out tube according to claim 4 , wherein:

the plurality of first encasing walls and the plurality of second encasing walls form a cylindrical structure, and

a diameter of the cylindrical structure is the same as an outer diameter of the pull-out tube.

6 . The joint structure configured for the pull-out tube according to claim 3 , wherein:

an inner wall of the magnetic component is embedded in the joint body, and

the outer wall of the magnetic component is embedded in the plurality of first encasing walls and the plurality of second encasing walls.

7 . A pull-out tube structure, comprising the pull-out tube and the joint structure according to claim 1 , wherein:

the pull-out tube comprises a first tube section and a second tube section, and

the two connecting heads of the joint structure are respectively disposed in the first tube section and the second tube section.

8 . A faucet, comprising:

the pull-out tube structure according to claim 7 , and

a magnetic switch, wherein:

the magnetic component of the pull-out tube structure is configured to correspond to the magnetic switch.

9 . A joint structure configured for a pull-out tube, comprising:

a joint body, and

two connecting heads respectively disposed on two ends of the joint body, and

a magnetic component, wherein:

the two connecting heads are configured to be connected to the pull-out tube,

the magnetic component is sleeved on an outside of the joint body by an insert molding process,

the joint body entirely encases an outside of the magnetic component,

one or more positioning holes exposing the magnetic component are formed on the joint body during the insert molding process, and

the one or more positioning holes are configured to enable a mould to position the magnetic component.

10 . A pull-out tube structure, comprising the pull-out tube and the joint structure according to claim 9 , wherein:

the pull-out tube comprises a first tube section and a second tube section, and

the two connecting heads of the joint structure are respectively disposed in the first tube section and the second tube section.
