Thus, the light-emitting device automatically emits light under the condition of insufficient light through the photosensitive device. Of course, the light emitting device of the present invention may also control its light emission by vibration or switch, for example, by pressing the switch to control the operation of the light emitting device, and the region of the insertion portion 2 corresponding to the pressing switch is designed to have a structure capable of realizing pressing or is made of a material with certain elasticity.

In order to enhance the tightness of the combination of the upper insert sheet 21 and the lower insert sheet 22, as shown in fig. 5 and 7, the upper surface of the insertion portion 2 is provided with a wedge-shaped protrusion 24, the wedge-shaped protrusion 24 is inclined in a direction away from the insertion portion 2 along the insertion direction of the insertion portion 2, and when at least part of the insertion portion 2 is inserted into the insertion cavity 11, the wedge-shaped protrusion 24 abuts against the cavity wall of the insertion cavity 11. Therefore, the inserting part 2 can further enhance the compression effect between the upper inserting sheet 21 and the lower inserting sheet 22 under the action of the wedge-shaped protrusion 24, and further improve the reliability of the sealing connection of the upper inserting sheet 21 and the lower inserting sheet 22. As shown in fig. 7, the wedge-shaped protrusion 24 may be provided on the lower surface of the insertion portion 2, or the wedge-shaped protrusion 24 may be provided on both the upper and lower surfaces of the insertion portion 2.

As shown in fig. 10, the present invention further discloses a zipper, which includes a pair of fastener tapes (not shown in the drawings), a slider 5 and the waterproof pull 100 of the present invention, wherein the fastener tapes are provided with fastener elements (not shown in the drawings), the slider 5 is used for engaging or disengaging the fastener elements on the pair of fastener tapes, and the waterproof pull 100 is connected to the slider 5 for pulling the slider 5 to move. The structure of the waterproof pull handle 100 is specifically referred to above.

Further, a pull tab 51 is provided on the slider 5, and the waterproof pull 100 is connected to the pull tab 51. Wherein the waterproof pull handle 100 is connected with the pull tab 51 through a connecting rope 6; in another embodiment, as shown in fig. 7, an integrally formed connecting structure 7 may be further disposed on the housing 1 or the insertion portion 2 for connecting products such as a zipper, a bag, a garment, a necklace, etc. In another embodiment, the waterproof pull 100 may be directly used as the pull tab 51 of the zipper slider 5, in which case the zipper slider 5 is provided with a pull tab, and the waterproof pull 100 is provided with a coupling hole for coupling the pull tab, the coupling hole being provided at one end of the housing 1 or the insertion portion 2, but the waterproof pull 100 may also be directly connected to the pull tab by a connecting rope.
