DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] Please refer to FIG. 1 to FIG. 6, a first embodiment of a self-power-generating water outflow device with a light comprises a water outflow terminal 10 and a connector 20.

[0024] An inner side of the water outflow terminal 10 comprises a light emitting diode (LED) light source 11 and a driving circuit for driving the LED light source (not shown). The water outflow terminal 10 further comprises a first positive electrode 31 and a first negative electrode 32 electrically connected to the driving circuit. As shown in FIG. 5, the LED light source 11 is disposed on an outer circumference of a water outflow 101 of the water outflow terminal 10.

[0025] In this embodiment, a top of the water outflow terminal 10 comprises an assembly cavity 12.

[0026] In this embodiment, a bottom wall of the assembly cavity 12 comprises a first accommodating groove 121 and a second accommodating groove 122. The first positive electrode 31 and the first negative electrode 32 are both sheets and are respectively fixedly disposed in the first accommodating groove 121 and the second accommodating groove 122.

[0027] In this embodiment, the first accommodating groove 121 is annular, and the second accommodating groove 122 is circular and located in the first accommodating groove 121. The first positive electrode 31 is an annular sheet. The first negative electrode 32 is a circular sheet. As shown in FIG. 5, the first accommodating groove 121 and the second accommodating groove 122 are arranged concentrically. Sealing grooves 13 are disposed between the first accommodating groove 121 and the second accommodating groove 122 and at an outer side of the first accommodating groove 121. Two sealing rings 14 are respectively disposed in the two sealing grooves 13.

[0028] As shown in FIG. 5, the assembly cavity 12 comprises an internal thread 123.

[0029] The connector 20 is detachably connected to the water outflow terminal 10 and comprises a connection housing 21 and a self-power-generating component 200. The self-power-generating component 200 is disposed in the connection housing 21, and the connection housing 21 comprises one or more second positive electrodes 211 and one or more second negative electrodes 212 electrically connected to the self-power-generating component 200. When the connector 20 is connected to the water outflow terminal 10, the first positive electrode 31 is in contact with the one or more second positive electrodes 211, and the first negative electrode 32 is in contact with the one or more second negative electrodes 212.

[0030] In this embodiment, a bottom of the connection housing 21 is coupled to the assembly cavity 12.

[0031] In this embodiment, the one or more second positive electrodes 211 and the one or more second negative electrodes 212 are both column-shaped bodies.

[0032] In this embodiment, the one or more second positive electrodes 211 comprise two second positive electrodes 211 symmetrically arranged, and the one or more second negative electrodes 212 comprise a second negative electrode 212. As shown in FIG. 2, the second negative electrode 212 is located between the two second positive electrodes 211.

[0033] In this embodiment, the connection housing 21 comprises an external thread 213, and the connector 20 is connected to the water outflow terminal 10 by engagement of the internal thread 123 of the assembly cavity 12 and the external thread 213 of the connection housing 21. The connection of the connection housing 21 and the water outflow terminal 10 can also be carried out in other manners, such as by snap fastening.

[0034] In this embodiment, the self-power-generating component 200 comprises a power generator 22 and an impeller 23. The impeller 23 is rotatably disposed in the connection housing 21, and the power generator 22 is fixedly disposed in the connection housing 21. The structure of the power generator 22 and the impeller 23 is conventional and will not be further described herein.

Specifically, a threaded hole may be disposed on a side wall of the connection housing 21, and an external thread is disposed on an outer circumference of the limiting column. A threaded engagement of the threaded hole and the external thread enables the limiting column to be laterally and movably disposed on the connection housing 21. When rotation of the impeller 23 needs to be limited, it is only necessary to rotate the limiting column to cause an end of the limiting column to be located between blades of the impeller 23. When the impeller 23 is to be reset to rotate, it is only necessary to rotate the limiting column to cause the end of the limiting column to move away from the impeller 23.

[0037] The limiting mechanism 30 can also adopt other structures as needed, such as a button structure of a ballpoint pen, which can drive the limiting column to move. The structure of the limiting mechanism 30 is not limited to what is disclosed, and can include other structures that can control the rotation of the impeller 23.
