As shown in FIGS. 1-9, in one embodiment, the present disclosure provides a waterproof light string 100. The waterproof light string 100 includes a wire assembly 120, lamp beads 130, and waterproof assemblies 110.

The wire assembly 120 includes wire groups 121 and insulating layers 122. Each of the insulating layers 122 covers an outer side of a corresponding wire group 121 of the wire groups 121. Each of the wire groups 121 includes three wires. For instance, each of the wire groups 121 includes a first wire 1211, a second wire 1212, and a third wire 1213. It should be understood that in the embodiment of the present disclosure, the number of the wires included in each of the wire groups 121 is not limited to three, and four wires may be provided in other alternative embodiments.

The first wire 1211, the second wire 1212, and the third wire 1213 of each of the wire groups 121 are sequentially disposed at intervals. An outer side of the first wire 1211, outer side of the second wire 1212, and an outer side of the third wire 1213 of each of the wire groups 121 are covered by the corresponding insulating layer 122. The insulating layers 122 may be made from one of rubber, polyethylene (PE), polyvinyl chloride (PVC), etc. It should be understood that the insulating layers 122 are made from an insulating material that is flexible.

Each first shell 111 includes a first waterproof portion 1111 and a light-transmitting portion 1112 fixedly connected to the first waterproof portion 1111. Each light-transmitting portion 1112 is capable of transmitting light generated by a corresponding lamp bead 130 of the lamp beads 130, so that the light generated by the lamp beads emit outside of the waterproof light string 100. Each light-transmitting portion 1112 is transparent. In one optional embodiment of the present disclosure, each light-transmitting portion 1112 includes a convex transparent structure. In other words, each light-transmitting portion 112 is the convex transparent structure. Each light-transmitting portion 1112 is convexly disposed from a corresponding second shell 112 toward a corresponding first shell 111. It is understood that each light-transmitting portion 1112 is disposed outwardly from an inner surface of a corresponding first shell 111 toward an outer surface of the corresponding first shell 111, so as to realize light concentration of each light-transmitting portion 1112.

In one optional embodiment of the present disclosure, each first shell 111 further includes a first convex ring 1113 disposed around a periphery of a corresponding light-transmitting portion 1112. Each first convex ring 113 is connected to the corresponding light-transmitting portion 1112 and a corresponding first waterproof portion 1111. Optionally, the first waterproof portion 1111, the first convex ring 1113, and the light-transmitting portion 1112 of each first shell 111 are integrally formed by using a first mold.

In one optional embodiment of the present disclosure, each first waterproof portion 1111 and the corresponding second waterproof portion 1121 are connected together first and then covered by the corresponding waterproof cover 113. For instance, a waterproof groove 1115 is defines on one end of each first waterproof portion 1111 away from a corresponding light-transmitting portion 1112. A waterproof convex rib 1125 is disposed on one end of each second waterproof portion 1121 away from a corresponding positioning portion 1122. Each waterproof convex rib 1125 is placed in a corresponding waterproof groove 1115. A groove wall of each waterproof groove 1115 and the corresponding waterproof convex rib 1125 limit each other, which not only facilitates a connection between each first waterproof portion 1111 and the corresponding second waterproof portion 1121, but also facilitates each waterproof cover to cover a connection position between each first waterproof portion 1111 and the corresponding second waterproof portion 1121.

Optionally, each first waterproof portion 1111 includes first connecting structures 1116. Each second waterproof portion 1121 includes second connecting structures 1126.

Further, it is more conducive for each waterproof cover to cover the fixed connection position between each first waterproof portion 1111 and the corresponding second waterproof portion 1121. It should be understood that other connection methods may be used between each first waterproof portion 1111 and the corresponding second waterproof portion 1121, which are not limited thereto and are not described for details herein.

Each of the lamp beads 130 is limited between each first waterproof portion 1111 and the corresponding second waterproof portion 1121, and is fixed by the corresponding second shell 112. Specifically, each second waterproof portion 1121 includes a limiting structure 1127. Each limiting structure 1127 is configured to limit a corresponding lamp bead 130 to each second waterproof portion 1121. Each limiting structure 1127 is opposite to a corresponding positioning portion 1122.

Specifically, each limiting structure 1127 is disposed opposite to the corresponding first positioning groove 1128. In one optional embodiment of the present disclosure, each limiting structure 1127 includes two limiting plates 112a disposed opposite to each other to define a limit groove 112c. Each of the lamp beads 130 are placed in a corresponding limit groove 112c and limited by the two limiting plates 112a of each limiting structure 1127. In order to increase a limiting effect on each of the lamp beads 130, in other embodiments of the present disclosure, each limiting structure 1127 further includes limiting columns 112b. Two of the limiting columns 112b of each limiting structure 1127 are fixedly connected to one of the two limiting plate 112a of each limiting structure 1127. The limiting columns 112b of each limiting structure 1127 are located in the limit grooves 112c of each limiting structure 1127, so that the limiting columns 112b of each limiting structure 1127 effectively limit the corresponding lamp bead 130. It should be noted that each limiting structure 1127 in the embodiments of the present disclosure facilitates mounting and dismounting of the corresponding lamp beads 130. It is understood that a structure of each limiting structure 1127 configured to limit the corresponding lamp bead 130 is not limited thereto.

In the embodiment of the present disclosure, each second waterproof portion 1121 includes the limit structure 1127 for limiting the corresponding lamp bead 130. In order to increase the limitation and protection to each of the lamp beads 130, in one optional embodiment of the present disclosure, each first waterproof portion 1111 and each second waterproof portion 1121 further include structures for limiting the corresponding two adjacent wire groups 121. For instance, two first limiting grooves 1114 are defined on one end of each first waterproof portion 1111 away from a corresponding light-transmitting portion 1112. Two second limiting grooves 1124 are defined on one end of each second waterproof portion 1121 away from a corresponding positioning portion 1122. Each of the wire groups 121 is placed in a corresponding second limiting groove 1124 of a corresponding second waterproof portion 1121 and a corresponding first limiting groove 1114 of a corresponding first waterproof portion 1121. Specifically, each of the first limiting grooves 1114 and a corresponding second limiting groove 1124 are configured to limit a corresponding wire group 121. Namely, each of the wire groups 121 is placed in the corresponding first limiting groove 1114 and the corresponding second limiting groove 1124 opposite to the corresponding first limiting groove 1114, and is limited by the groove wall of a corresponding first limiting groove 1114 and the groove wall of a corresponding second limiting groove 1124. It is understood that each of the first limiting grooves 1114 and each of the second limiting grooves 1124 include sub-grooves. The number of the sub-grooves of each of the first limiting grooves 1114 and the number of the sub-grooves of each of the second limiting grooves 1124 are same as the number of the wires included in each of the wire groups 121.

Each waterproof cover 113 covers a corresponding first waterproof portion 1111 and a corresponding second waterproof portion 1121, and each waterproof cover 113 is fixedly connected to the corresponding first waterproof portion 1111 and the corresponding second waterproof portion 1121, so as to prevent liquid from entering each of the lamp beads 130 from a gap between each first waterproof portion 1111 and the corresponding second waterproof portion 1121.

Optionally, each waterproof cover 113 includes a first cover body 1131, a second cover body 1132, and a third cover body 1133.

Each first cover body 1131 covers a corresponding first convex ring 1113 and is fixedly connected to the corresponding first convex ring 1113. Each second cover body 1132 and a corresponding first cover body 1131 are integrally formed.

In one optional embodiment of the present disclosure, each first cover body 1131, the corresponding second cover body 1132, and the corresponding third cover body 1133 are integrally formed, such as integrally formed by using a third mold.

For instance, in the embodiments of the present disclosure, after the at least one light-emitting chip of each of the lamp beads 130 is welded to the corresponding two adjacent wire groups 121, each of the lamp beads 130 is fixedly connected to the corresponding two adjacent wire groups 121 each covered with the insulating layer 122. Parts of the corresponding two adjacent wire groups 121 are placed in the second waterproof portion 1121 of each second shell 112, and each of the lamp beads 130 is installed in a corresponding limiting structure 1127. Then, each first shell 111 and the corresponding second shell 112 are fixed, and each of the first limiting grooves 1114 and the corresponding second limiting groove 1124 are aligned with the corresponding wire group 121 to ensure that each of the wire groups 121 is located in the corresponding first limiting groove 1114 and the corresponding second limiting groove 1124. Then, each first shell 111 and the corresponding second shell 112 that are fixedly connected together are placed in a corresponding third mold, and the corresponding waterproof cover 113 is formed on an outer surface of the first waterproof portion 1111 thereof, an outer surface of the first convex ring 1113 thereof, an outer surface of the second waterproof portion 1121 thereof, and an outer surface of the second convex ring 1123 thereof. Therefore, each waterproof cover 113 not only covers the corresponding first waterproof portion 1111, the corresponding first convex ring 1113, the corresponding second waterproof portion 1121, and the corresponding second convex ring 1123, but also is fixedly connected to the corresponding first waterproof portion 1111, the corresponding first convex ring 1113, the corresponding second waterproof portion 1121, and the corresponding second convex ring 1123 to realize a stable fixed connection relationship and an effective waterproof performance of the waterproof light string.

A shape of each second cover body 1132 is matched with each first waterproof portion 1111 and each second waterproof portion 1121. A maximum diameter of each first cover body 1131 is not greater than a minimum diameter of each second cover body 1132. A maximum diameter of each third cover body 1133 is not greater a minimum diameter of each second cover body 1132. A minimum diameter of each third cover body is less than a minimum diameter of each first cover body. Therefore, it is ensured that each light-transmitting portion 1112 is sufficiently exposed from a corresponding first cover body 1131 to effectively transmit light. Each waterproof cover 113 is light-proof. For instance, each first cover body 1131, each second cover body 1132, and each third cover body 1133 are light-proof, and each first cover body 1131, each second cover body 1132, and each third cover body 1133 are opaque.
