Description

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 consist of a bulb at the bottom and a transparent container on top. Inside the container are a mixture of liquid and wax, the density of which changes with temperature. When the bulb illuminates, 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. Because the bulb takes time to gather heat and heat up, it cannot quickly heat the wax to produce the buoyancy effect, resulting in a long start-up time. Therefore, existing lava lamps incorporate a heating element to accelerate heating. This heating element can be fixed to the bottom of the wax container by adhesive or a support frame. Since the heating element is in direct contact with the wax, the heat generated by it tends to concentrate in the central area of ​​the container. This results in a small heating area, uneven heat conduction, and the concentration of heat in the center, which can easily lead to the wax container breaking. Utility Model Content

[0028] It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0029] Reference Figures 1 to 10 The following are embodiments of the lava lamp of this utility model:

[0030] A lava lamp includes a base 20, a light source 40 installed within the base 20, a wax bottle 10 containing liquid wax connected to the base 20, a heating unit installed at the bottom of the wax bottle 10, and a support structure installed within the base 20 to support the heating unit. The light source 40 emits light towards the wax bottle 10. A heat-conducting ring 5 with a central perforation is provided between the wax bottle 10 and the heating unit, with the perforation facing the center of the bottom of the wax bottle 10. The heat-conducting ring 5 diffuses the heat from the heating unit to the wax bottle 10, preventing heat from accumulating at the center of the bottom of the wax bottle 10, thus enhancing safety.

[0031] Heating wax bottle 10 creates a floating effect in the lava lamp. The slow, flowing wax effect and soft light of the lava lamp help create a tranquil and relaxing environment, enhancing its artistic appeal.

[0032] The heating unit includes a PTC constant temperature heating element and a high thermal conductivity insulating sleeve. The high thermal conductivity insulating sleeve wraps around the PTC constant temperature heating element, forming an insulating heating body 30. The wire electrically connected to the PTC constant temperature heating element extends from the high thermal conductivity insulating sleeve.

[0033] The heating unit also includes a heat-conducting component 3, which has a horizontally positioned slot 31 adapted to the insulating heating element 30. The insulating heating element 30 is inserted into the slot 31 for easy installation. The lower end face of the heat-conducting ring 5 is attached to the heat-conducting component 3, and the upper end face of the heat-conducting ring 5 is attached to the bottom surface of the wax bottle 10. The insulating heating element 30 is in contact with the heat-conducting component 3, and heat is conducted to the heat-conducting ring 5 through the heat-conducting component 3, and then to the wax bottle 10 through the heat-conducting ring 5.

[0034] The heat-conducting ring 5 is a silicone ring. The outer diameter of the heat-conducting ring 5 is larger than that of the heat-conducting component 3, which increases the heat diffusion area.

[0035] The bottom of the heat-conducting component 3 is provided with a linear slot 32. A screw 33 is installed in the slot 32. The head of the screw 33 is inserted into the slot 32 from the end of the slot 32, and the shank of the screw 33 extends out from the slot 32 and is connected and fixed to the support structure.

[0036] The support structure includes a spring pin 2 and a fixed support part 1 connected from top to bottom. The upper end of the spring pin 2 is an elastic pressing end, and the heat-conducting component 3 is supported on the elastic pressing end of the spring pin 2. The bottom surface of the wax bottle 10 has a light-entry area for light to enter, and the light-entry area is located outside the heat-conducting ring 5. The light source 40 is located below the heating unit, and the light emitted by the light source 40 enters the wax bottle 10 through the light-entry area.

[0037] In this embodiment, the fixed support part 1 is a hollow column with a through hole running through it axially. The upper end of the through hole serves as a mounting hole 11 for inserting the spring pin 2. The spring pin 2 is inserted into the mounting hole 11, and the elastic pressing end of the spring pin 2 extends out from the mounting hole 11 to support the heating unit.

[0038] The spring pin 2 has a threaded hole 25 on its elastic pressing end. The shank of the screw 33 is inserted into the threaded hole 25 to connect the heat-conducting component 3 and the spring pin 2.

[0039] The spring pin 2 includes an outer sleeve 21, a movable rod 22, and a spring. The outer sleeve 21 has a radially arranged abutment surface 232. The movable rod 22 passes through the outer sleeve 21 and through the abutment surface 232. In this embodiment, the bottom surface of the outer sleeve 21 serves as the abutment surface 232. The lower end of the movable rod 22 protrudes from the abutment surface 232 and is fitted with a retaining ring 24, which limits the lower end of the movable rod 22 below the abutment surface 232, preventing the movable rod 22 from being pulled out of the outer sleeve 21. A shoulder 231 is provided around the movable rod 22. The shoulder 231 is opposite to and above the abutment surface 232, and a spring mounting position 23 is formed by the relative spacing between the shoulder 231 and the abutment surface 232. The spring is fitted onto the movable rod 22 and located in the spring mounting position 23. The upper end of the spring abuts against the shoulder 231, and the lower end of the spring abuts against the abutment surface 232. The movable rod 22 is supported within the outer casing 21 by a spring, with its upper end extending outside the casing 21, serving as the elastic pressing end of the spring needle 2. The wax bottle 10 presses the heating unit via the heat-conducting ring 5, thereby pressing the elastic pressing end of the spring needle 2, causing the movable rod 22 to move downwards. This, in turn, compresses the spring through the shoulder 231, generating an upward elastic force. The generated elastic force keeps the heat-conducting ring 5 tightly against the bottom of the wax bottle 10, and the heat is conducted to the wax bottle 10 by the heat-conducting ring 5. The spring needle 2 is highly rigid, and using a spring needle to provide elastic force prevents it from wobbling from side to side, thus providing strong stability while meeting the elastic force requirements.

[0040] The upper end of the outer sleeve 21 is provided with an overlapping ring. The outer sleeve 21 is inserted into the mounting hole 11 of the fixed support part 1. The overlapping ring is placed on the upper edge of the mounting hole 11. The mounting hole 11 and the outer sleeve 21 fit tightly to prevent the spring pin 2 from shaking.

[0041] The outer wall of the fixed support part 1 is provided with an external thread 13 and a support ring 12 located below the external thread 13. A light source mounting platform 4 and an insulating disk 41 for mounting the light source component 40 are fitted on the fixed support part 1. The light source mounting platform 4 is supported on the support ring 12, and the insulating disk 41 is mounted on the light source mounting platform 4. The light source mounting platform 4 is pressed onto the support ring 12 by a nut 14 that engages with the external thread 13. The light source component 40 is an LED light source board. The light source component 40 is placed on the insulating disk 41 and passes through the fixed support part 1. The nut 14 is installed on the fixed support part 1 by the external thread 13. The nut 14 is pressed onto the light source component 40. The light source component 40, the insulating disk 41 and the light source mounting platform 4 are pressed onto the support ring 12 by the nut 14 that engages with the external thread 13.
