Abstract
Description
Technical Field
[0001] This utility model relates to the field of inflatable decorative lights, and in particular, to an inflatable decorative lamp. Background Technology
[0002] With social development and technological progress, inflatable decorative toys are everywhere. However, combining inflatable toys with colored lights to create decorative lighting fixtures is still very rare on the market. The reason for this is that the sealing problem between the wires and the inflatable body cannot be solved.
[0003] For example, patent number 201620605243.2 discloses an inflatable lantern, which includes a lantern, an inflation nozzle, a sealing cover, a sealed power lead wire, a spiral lamp holder, a hanging light strip, and a positioning ring. The sealed power lead wire is provided on the sealing cover of the inflation nozzle of the inflatable lantern, and the power line of the light string is connected to the sealed power lead wire of the lantern for power supply.
[0004] In the above structure, a sealing power lead is provided on the sealing cover of the inflation nozzle of the inflatable lantern. There is a gap between the sealing cover and the power lead, which cannot achieve a true seal and is prone to causing air leakage in the inflatable bag, resulting in low practicality.
[0005] To address the aforementioned issues, patent number 202322974188.7 discloses an inflatable decorative lamp, which employs a design where the open end is welded to the outside of the outlet, allowing the transparent sealing sleeve to communicate with the outside through the outlet for sealing. This patent uses one chamber within the inflatable bladder and another chamber where the sealing sleeve is used for the LED strip and communicates with the outside. While the dual-chamber structure achieves true sealing, the arrangement of the LED strip depends entirely on the shape of the sealing sleeve, and the complex structure of the sealing sleeve makes it difficult to thread the LED strip through, resulting in a limited range and outline of illumination. This fails to fully realize the decorative characteristics of combining an inflatable toy with colored lights into a decorative lamp. Therefore, this utility model proposes an inflatable decorative lamp that does not limit the arrangement of the LED strip and achieves true sealing. Utility Model Content
[0006] The purpose of this utility model is to address the shortcomings of the existing technology, at least to a certain extent, the technical problems in the related technology, and to solve the problems of limited light strip arrangement and poor sealing of existing inflatable decorative lamps.
[0007] An inflatable decorative lamp includes an inflatable, expandable bladder made of plastic and a conductive wire wrapped in rubber. The bladder has a wire outlet, and the conductive wire has an integrally formed sealing section. A welding piece is provided outside the sealing section, which is welded to the bladder and covers the outer ring of the wire outlet to seal it. One end of the conductive wire extends into the bladder, and the other end is outside the bladder. The end of the conductive wire inside the bladder is connected to a light source, and the end of the conductive wire outside the bladder is connected to a power source or plug.
[0008] Furthermore, the sealing section includes a sealing body wrapped around the conductive wire and a hollow sealing column. The sealing body is connected to the sealing column, the conductive wire is placed inside the sealing column and extends out of the sealing column, the sealing column is filled with sealant, and after welding, the sealing column extends into the wire outlet.
[0009] Furthermore, the welding strip can be disposed on the sealing body, on the sealing post, or between the sealing body and the sealing post.
[0010] Furthermore, the sealing body, sealing column, and welding sheet are integrally formed on the conductive line.
[0011] Furthermore, a counterweight bag is formed at the bottom of the inflatable bladder body. The counterweight bag is a water-filled bag. The bottom of the counterweight bag is provided with a water inlet for adding water to the water-filled bag. A removable water inlet plug is installed on the water inlet.
[0012] Furthermore, the inflatable bladder has an inflation chamber inside, and the inflatable bladder has an inflation port for inflating the inflation chamber, and an insertable inflation port plug is installed on the inflation port.
[0013] Furthermore, the light source can be a string of light bulbs, a string of light bulbs, an LED light strip, a light bead, or a light bulb, and the light source is located on the inner wall of the inflatable bladder.
[0014] Furthermore, the power source is a solar cell box, a rechargeable battery box, or a regular battery box; the plug is a USB plug, a plug with a power adapter, or a male-female connector plug.
[0015] Furthermore, the inflatable bladder, the counterweight bag, the sealing body, the sealing column, and the welded sheet are made of PVC or TPU material.

[0019] Step c: Process a sealing section with a welded plate. The sealing section includes a connected sealing body and a sealing post. Take a conductive wire connected to a power source or plug, and use an injection molding machine to integrally mold the sealing section and welded plate on the outside of the conductive wire, so that the sealing body tightly wraps around the outside of the conductive wire, and fill the sealing post with sealant.
