Description

Technical Field

[0001] The utility model relates to the field of lamps, in particular to a supporting structure of a lava lamp and a lava lamp. Background Art

[0002] Lava lamps are also called jellyfish lamps or wax lamps. They look like lava flowing inside a glass bottle. The principle is to use simple thermodynamic principles to make liquid wax move up and down in a sealed glass bottle like lava, creating a magical light and shadow effect.

[0003] A lava lamp typically features a bulb at the bottom, atop a transparent container. The container contains a liquid and waxy solids whose density varies with temperature. When the bulb is lit, heat is generated, transferring from the bottom to the transparent container. The wax at the bottom melts and gradually becomes lighter, slowly rising. When it reaches the top, it cools slightly and then slowly falls back, creating a floating effect. Because the bulb takes time to generate heat, it can't quickly heat the wax container to create the floating effect, resulting in a long startup time. Therefore, existing lava lamps incorporate a heating element to accelerate heating. The heating element can be fixed to the bottom of the wax container using adhesive or a support frame. Adhesive bonding offers a simple structure, but it's inconvenient to remove after bonding. Patent application number CN201420215737.0, entitled "A Lava Lamp," discloses a structure that uses a spring to support a heating coil. The spring compresses the heating coil, keeping it in close contact with the bottom of the wax container, ensuring sufficient contact and heat conduction. However, this spring support is unstable and prone to swaying, causing the heating coil to shift position. Utility Model Content

[0036] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0037] Reference Figures 1 to 8 , an embodiment of the support structure of the lava lamp of the utility model is proposed:

[0038] A lava lamp support structure comprises a fixed support portion 1, an elastic support portion 2, and a connecting portion 3, connected sequentially from bottom to top. The connecting portion 3 is located at the top and is used to mount a heating element 30. The elastic support portion 2 is a spring pin. The upper end of the spring pin is an elastic pressing end, and the connecting portion 3 is supported on the elastic pressing end of the spring pin.

[0039] In this embodiment, the fixed support portion 1 is a hollow cylinder with a through hole axially extending therethrough. The upper end of the through hole serves as a mounting hole 11 for inserting a spring pin. The spring pin is inserted into the mounting hole 11, and the elastic pressing end of the spring pin extends from the mounting hole 11 to support the connecting portion 3.

[0040] The spring pin 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 penetrates the outer sleeve 21 and extends 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 extends beyond the abutment surface 232 and is fitted with a retaining ring 24, which constrains the lower end of the movable rod 22 below the abutment surface 232, preventing the movable rod 22 from being removed from the outer sleeve 21. A boss 231 is provided around the movable rod 22. The boss 231 is opposite to and located above the abutment surface 232. The boss 231 and the abutment surface 232 are spaced relative to each other to form a spring mounting position 23. The spring is mounted on the movable rod 22 and located in the spring mounting position 23. The upper end of the spring abuts against the boss 231, and the lower end of the spring abuts against the abutment surface 232. The movable rod 22 is supported in the outer sleeve 21 by a spring, and the upper end of the movable rod 22 extends outside the outer sleeve 21 and serves as the elastic pressing end of the elastic pin. Pressing the elastic pressing end of the elastic pin causes the movable rod 22 to move downward, thereby squeezing the spring through the shoulder 231 to generate an upward elastic force.

[0041] The bottom of the connecting portion 3 is provided with a linear slot 32, and the head of a screw 33 is inserted into the slot 32 from the end of the slot 32, thereby connecting the screw 33 to the connecting portion 3. The elastic pressing end of the spring pin is provided with a threaded hole 25, and the screw 33 is inserted into the threaded hole 25 to connect and fix the connecting portion 3 to the elastic pressing end of the spring pin.

[0042] A lap ring is provided around the upper end of the outer sleeve 21. The outer sleeve 21 is inserted into the mounting hole 11 of the fixed support part 1. The lap ring is placed on the upper end edge of the mounting hole 11. The mounting hole 11 and the outer sleeve 21 fit tightly to prevent the spring pin from shaking.

[0043] When used in a lava lamp, the support structure is installed below the wax bottle, and the heater is installed at the upper end of the connection or within the connection. When the heater is installed at the upper end of the connection, the support structure supports the heater at the bottom of the wax bottle, and the elastic force generated by the spring pins keeps the heater in close contact with the bottom of the wax bottle. When the heater is installed within the connection, the connection is made of thermally conductive material, and the elastic force generated by the spring pins keeps the connection in close contact with the bottom of the wax bottle, transferring heat from the connection to the wax bottle. The spring pins are highly rigid, and using them to provide elastic force prevents side-to-side movement, thus meeting the elastic force requirements while providing strong stability.

[0044] In this embodiment, the connecting portion 3 is made of a heat-conducting material and is provided with a plug-in slot 31 for inserting the heating element 30, which facilitates the installation of the heating element 20. The top of the connecting portion 3 is an arc-shaped surface that fits the center of the bottom of the wax bottle to improve the thermal conductivity.

[0045] The outer wall of the fixed support portion 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 for mounting a light source component 40 is mounted on the fixed support portion 1. The light source mounting platform 4 is supported on the support ring 12 and is pressed against the support ring 12 by a nut 14 engaged with the external thread 13, thereby connecting and fixing the light source mounting platform 4 to the fixed support portion 1.

[0046] Reference Figures 1 to 10 , an embodiment of the lava lamp of the present utility model is proposed:

[0047] A lava lamp includes a base 20, a light source 40 mounted within the base 20, a wax bottle 10 connected to the base 20 and containing liquid wax, a heating element 30 mounted at the bottom of the wax bottle 10, and a support structure mounted within the base 20 for supporting the heating element 30. The light source 40 emits light toward the wax bottle 10. The heating element 30, mounted at the bottom of the wax bottle 10, heats the wax bottle, creating a floating effect in the lava lamp. The lava lamp's slow, flowing wax effect and soft light can help create a tranquil and relaxing environment, adding to the artistic appeal of the space.

[0048] The support structure consists of a fixed support portion 1, an elastic support portion 2, and a connecting portion 3, connected sequentially from bottom to top. The connecting portion 3 is located at the top and is used to mount the heating element 30. The elastic support portion 2 is a spring pin. The upper end of the spring pin is an elastic pressing end, and the connecting portion 3 is supported by the elastic pressing end of the spring pin.

[0049] In this embodiment, the connecting portion 3 is provided with a slot 31 for inserting the heating element 30. The heating element 30 is inserted into the slot 31, facilitating assembly of the heating element 30. The connecting portion 3 is made of a thermally conductive material. The heating element 30 transfers heat to the connecting portion 3, which in turn transfers the heat to the wax bottle 10. The top surface of the connecting portion 3 is in close contact with the bottom of the wax bottle 10. The top surface of the connecting portion 3 is an arc-shaped surface that aligns with the center of the bottom of the wax bottle 10, improving thermal conductivity.

[0050] The bottom surface of the wax bottle 10 has a light entrance area for light to enter, and the light entrance area is located outside the connecting portion 3. The light source 40 is located below the connecting portion 3, and the light emitted by the light source 40 enters the wax bottle 10 from the light entrance area.

[0051] The heating element 30 is an insulating heating element composed of a PTC constant temperature heating sheet and a high thermal conductivity insulating sleeve wrapped around the PTC constant temperature heating sheet, and is safe to use. The wax bottle 10 is heated by the heat generated by the PTC constant temperature heating sheet to achieve constant temperature heating.

[0052] In this embodiment, the fixed support portion 1 is a hollow cylinder with a through hole axially extending therethrough. The upper end of the through hole serves as a mounting hole 11 for inserting a spring pin. The spring pin is inserted into the mounting hole 11, and the elastic pressing end of the spring pin extends from the mounting hole 11 to support the connecting portion 3.

[0053] The spring pin 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 penetrates the outer sleeve 21 and extends 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 extends beyond the abutment surface 232 and is fitted with a retaining ring 24, which constrains the lower end of the movable rod 22 below the abutment surface 232, preventing the movable rod 22 from being removed from the outer sleeve 21. A boss 231 is provided around the movable rod 22. The boss 231 is opposite to and located above the abutment surface 232. The boss 231 and the abutment surface 232 are spaced relative to each other to form a spring mounting position 23. The spring is mounted on the movable rod 22 and located in the spring mounting position 23. The upper end of the spring abuts against the boss 231, and the lower end of the spring abuts against the abutment surface 232. The movable rod 22 is supported within the outer sleeve 21 by a spring. The upper end of the movable rod 22 extends outside the outer sleeve 21 and serves as the elastic pressing end of the spring pin. The wax bottle 10 squeezes the connecting portion 3, thereby pressing the elastic pressing end of the spring pin, causing the movable rod 22 to move downward. This, in turn, compresses the spring via the shoulder 231 to generate an upward elastic force. This generated elastic force causes the connecting portion 3 to adhere to the bottom of the wax bottle 10, allowing the connecting portion 3 to transfer heat to the wax bottle 10. The spring pin is highly rigid, and using the spring pin to provide the elastic force prevents swaying, thereby providing strong stability while meeting the elastic force requirement.

[0054] The bottom of the connecting portion 3 is provided with a linear slot 32, and the head of a screw 33 is inserted into the slot 32 from the end of the slot 32, thereby connecting the screw 33 to the connecting portion 3. The elastic pressing end of the spring pin is provided with a threaded hole 25, and the screw 33 is inserted into the threaded hole 25 to connect and fix the connecting portion 3 to the elastic pressing end of the spring pin.

[0055] A lap ring is provided around the upper end of the outer sleeve 21. The outer sleeve 21 is inserted into the mounting hole 11 of the fixed support part 1. The lap ring is placed on the upper end edge of the mounting hole 11. The mounting hole 11 and the outer sleeve 21 fit tightly to prevent the spring pin from shaking.

[0056] The outer wall of the fixed support portion 1 is provided with external threads 13 and a support ring 12 positioned below the external threads 13. A light source mounting base 4 for mounting a light source component 40 is mounted on the fixed support portion 1. The light source mounting base 4 is supported on the support ring 12 and is pressed against the support ring 12 by a nut 14 engaged with the external threads 13, thereby connecting and securing the light source mounting base 4 to the fixed support portion 1. The light source component 40 is an LED light source board, and an insulating disk is mounted within the light source mounting base 4, within which the light source component 40 is mounted.

[0057] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformation made using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, is also included in the patent protection scope of the present invention.
