Description

A lava lamp Technical Field

[0001] This utility model relates to the field of lighting fixtures, and in particular to a lava lamp. Background Technology

[0002] Lava lamps, also known as jellyfish lamps or wax lamps, create the illusion of flowing lava inside a glass bottle. The principle behind this is the use of simple thermodynamics to make liquid wax move up and down like lava within a sealed glass bottle, creating a magical light and shadow effect.

[0003] Lava lamps typically have a bulb at the bottom and a transparent container on top. The container contains a liquid and a waxy solid whose density changes with temperature. When the bulb lights up, heat is transferred from the bottom to the container. The wax at the bottom melts and becomes lighter, causing it to rise slowly. Upon reaching the top and cooling slightly, it slowly falls back down, creating a buoyancy effect. However, because the bulb takes time to gather heat, it cannot quickly heat the wax bottle to produce the buoyancy effect, resulting in a long start-up time. Therefore, existing lava lamps incorporate a heating element to accelerate heating. The heating element can be fixed to the bottom of the wax bottle by adhesive bonding or a support frame. While adhesive bonding is simple, it makes disassembly inconvenient. Patent application CN201420215737.0, entitled "A Lava Lamp," discloses a structure using springs to support the heating coil, requiring multiple springs and individual assembly. The technical problem this utility model aims to solve is to design a simple heating element mounting structure. Utility Model Content
