Description

Technical Field

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

[0002] Lava lamps, also known as jellyfish lamps or wax lamps, mainly consist of a lava bottle and a lamp base. The lamp base contains a light-emitting element, and the lava bottle is mounted on the base, with the light-emitting element pointing towards the bottom of the lava bottle. The lava bottle contains a liquid and a waxy solid whose density changes with temperature. A heating element is located at the bottom of the lava bottle, heating it and using simple thermodynamic principles to melt the waxy solid within. As the wax melts and becomes lighter, it slowly rises, and upon reaching the top and cooling slightly, it slowly falls back down, creating a floating light and shadow effect, much like lava itself.

[0003] A lava lamp disclosed in Chinese utility model patent document CN222122935U uses a PCT heating element attached to the bottom of a lava bottle to heat the lava bottle, wherein the PCT heating element is supported and fixed by a bracket. The heating element is placed on the outside of the lava bottle, causing some heat to dissipate into the surrounding environment, thus reducing heating efficiency.

[0004] The larger the contact area between the heating element and the lava bottle, the faster the heat conduction. However, the light-emitting element illuminates the lava bottle by shining light on its bottom, and an empty space needs to be left at the bottom of the lava bottle for the light-emitting element to shine on. Therefore, the heat conduction area between the bottom of the lava bottle and the heating element is limited, and the heat transfer between the two is not sufficient, resulting in slow heating of the wax inside the lava bottle. Utility Model Content

[0005] The main purpose of this utility model is to provide a lava lamp and its heating structure, which aims to solve the problem of low heat conduction efficiency in the existing lava lamps that use PCT heating elements attached to the bottom of the lava bottle to heat the lava bottle.

[0006] This utility model proposes a heating structure for a lava lamp, including a heat source mounting groove with a accommodating depth recessed at the bottom of a lava bottle and a heating head with a thermally conductive height. The heating head includes a heat-conducting element and an electric heating unit that contacts and transfers heat with the heat-conducting element. The heating head extends into the heat source mounting groove.

[0007] Preferably, the electric heating unit is an electric heating element, and the heat-conducting component has a through-hole adapted to the electric heating element, and the electric heating element is installed in the through-hole.

[0008] Preferably, the electric heating element is composed of a PTC heating element and a high thermal conductivity insulating sleeve wrapped around the PTC heating element, and the wire electrically connected to the PTC heating element extends from the heat source mounting groove to be electrically connected to an external power source.

[0009] Preferably, it further includes a heat source baffle, the heat source baffle including a crossbar placed horizontally at the bottom of the heating head; the heat source baffle includes an empty area corresponding to the bottom of the lava bottle, so that the light from the light-emitting element passes through the empty area to illuminate the lava bottle.

[0010] Preferably, the heat source mounting slot is vertically oriented, and the heating head is vertically mounted in the heat source mounting slot.

[0011] Preferably, the heat-conducting component is a cylindrical aluminum head made of aluminum material, and the heat source mounting groove is a cylindrical groove adapted to the heat-conducting component.

[0012] Preferably, the heat source baffle includes an outer ring, the crossbar is placed horizontally inside the outer ring, the two ends of the crossbar are connected to the outer ring, and the empty area is located inside the outer ring and on both sides of the crossbar.

[0013] This utility model proposes a lava lamp, including a light source base, a light-emitting element installed in the light source base, a lava bottle supported on the light source base, and a heating structure for heating the lava bottle. The light-emitting element illuminates the lava bottle, and the heating structure is the heating structure of the lava lamp proposed above.

[0014] Preferably, the lower end of the lava bottle is inserted into the light source holder, the inner wall of the light source holder is provided with an annular support platform, the heat source baffle and the lava bottle are supported on the annular support platform, and the lava bottle is pressed on the heat source baffle.

[0015] Preferably, the light source holder includes a base body and a straight cup with openings at both ends connected to the base body, the light-emitting element is installed in the base body, and the annular support platform is disposed on the inner wall of the straight cup.

[0016] Preferably, the lava lamp further includes a counterweight base, and the light source base is directly mounted on the counterweight base or indirectly mounted on the counterweight base through a support member.

[0017] The beneficial effects of this lava lamp are as follows:

[0018] By creating a recessed heat source mounting groove at the bottom of the lava bottle and inserting a heating head with thermal conductivity into this groove, heat is concentrated within the groove, reducing heat loss. This also allows for a larger contact area between the heating head and the lava bottle, increasing the heat conduction area and improving heat transfer efficiency. Compared to existing technologies where the PCT heating element is only attached to the outer surface of the lava bottle's bottom, this novel heating head insertion design allows heat to be transferred more directly and quickly to the interior of the lava bottle, resulting in faster heat conduction and higher heating efficiency. Simultaneously, the heat source baffle design supports and positions the heating head without obstructing the light from the luminous element, ensuring the lava lamp's illumination effect.

[0029] 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.

[0030] Example 1:

[0031] Reference Figures 1 to 4 A heating structure for a lava lamp includes a heat source mounting groove 11 recessed at the bottom of a lava cylinder 1, having a receiving depth, and a heating head 2 with a thermally conductive height. The heating head 2 includes a heat-conducting element 21 and an electric heating unit 22 that contacts and transfers heat to the heat-conducting element 21. The heating head 2 extends into the heat source mounting groove 11. With the heating head 2 inserted within the heat source mounting groove 11, heat is concentrated within the heat source mounting groove 11, reducing heat loss.

[0032] The electric heating unit 22 is an electric heating element. The heat-conducting component 21 has a through-hole 211 that is adapted to the electric heating element, and the electric heating element is inserted into the through-hole 211.

[0033] The heating structure also includes a heat source baffle 3, which includes a horizontal bar 32. The horizontal bar 32 is positioned horizontally below the lava bottle 1 and at the bottom of the heating head 2 to support and position the heating head 2 in the heat source mounting groove 11. It also supports the electric heating element, preventing it from coming out of the insertion groove 211. This design allows the heating head 2 to be stably held within the heat source mounting groove 11, ensuring effective heat transfer. The heat source baffle 3 includes an empty area 33 corresponding to the bottom of the lava bottle 1, allowing light from the light-emitting element below the bottom of the lava bottle to pass through the empty area 33 and illuminate the lava bottle 1. This design ensures that the light from the light-emitting element is not blocked by the heat source baffle 3, effectively illuminating the lava flow inside the lava bottle 1 and enhancing the visual effect.

[0034] Furthermore, the horizontal bar 32 and the electric heating element are arranged in a cross shape.

[0035] The electric heating element consists of a PTC heating element and a high thermal conductivity insulating sleeve wrapped around the PTC heating element. The high thermal conductivity insulating sleeve can be made of high thermal conductivity silicone, such as the silicone sleeve made of thermally conductive silicone material disclosed in invention patents with publication numbers CN114525035B or CN116376292B. The silicone sleeve is elastic, allowing the electric heating element to be tightly installed in the insertion slot 11 and integrated with the heat-conducting component 21.

[0036] Of course, the electric heating element can also be a PTC heating element. The PTC heating element is inserted into the insertion slot, and the insertion slot is filled with insulating thermally conductive adhesive. The insulating thermally conductive adhesive wraps around the PTC heating element and fills the gap between the insertion slot and the PTC heating element, so that the PTC heating element and the heat-conducting component are integrated into one.

[0037] A wire connected to the PTC heating element extends from the heat source mounting slot 11 to connect to an external power source. When the power is turned on, the PTC heating element generates heat, which is transferred to the heat-conducting component 21 through a high thermal conductivity insulating sleeve. The heat-conducting component 21 then transfers the heat to the bottom of the lava bottle 1, causing the waxy material inside the lava bottle 1 to melt and produce a flowing effect.

[0038] The heat source mounting slot 11 is vertically oriented, and the heating head 2 is vertically installed in the heat source mounting slot 11. This vertical design facilitates the installation of the heating head 2.

[0039] The top and sidewalls of the heating head 2 are in contact with the inner wall of the heat source mounting groove 11. Of course, in other embodiments, a small gap may be left between the sidewalls of the heating head 2 and the inner wall of the heat source mounting groove 11.

[0040] In a preferred embodiment, the heat-conducting element 21 is a cylindrical aluminum head made of aluminum, and the heat source mounting groove 11 is a cylindrical groove adapted to the heat-conducting element 21. Aluminum has good thermal conductivity, which can quickly and evenly transfer heat, while the cylindrical design provides sufficient contact area to ensure that heat is effectively transferred to the bottom of the lava bottle.

[0041] The heat source baffle 3 includes an outer ring 31, with a horizontal bar 32 placed inside the outer ring 31. Both ends of the horizontal bar 32 are connected to the outer ring 31. An empty area 33 is located inside the outer ring 31 and on both sides of the horizontal bar 32. The heat source baffle 3 is integrally formed. The outer ring 31 is used for mounting the heat source baffle 3, allowing it to be placed on a corresponding annular platform. This structural design allows the heat source baffle 3 to be installed via the outer ring 31, to stably support the heating head via the horizontal bar 32, and to maximize the space for light to pass through, ensuring the lava bottle is fully illuminated.

[0042] This lava lamp's heating structure achieves efficient heating of the lava bottle through a rationally designed heat source mounting slot and the relative positions of the heating head. Simultaneously, the design of the heat source baffle ensures the stability of the heating head without affecting the luminous effect, allowing the lava lamp to present an aesthetically pleasing visual appearance.

[0043] Example 2:

[0044] Reference Figures 1 to 9 A lava lamp includes a light source base 4, a light-emitting element 5 installed in the light source base 4, a lava bottle 1 supported on the light source base 4, and a heating structure for heating the lava bottle 1. The light-emitting element 5 illuminates the lava bottle 1, and the heating structure adopts the heating structure described in Embodiment 1.

[0045] The lava bottle 1 is cylindrical, and the light source base 4 is also cylindrical. The upper end of the light source base 4 is open, and the lower end of the lava bottle 1 is inserted into the light source base 4 through this opening. The outer wall of the lava bottle 1 fits against the inner wall of the light source base 4. The inner wall of the light source base 4 is provided with an annular support platform 421. The outer ring 31 of the heat source baffle 3 and the lava bottle 1 are supported on the annular support platform 421, and the lava bottle 1 is pressed against the outer ring 31 of the heat source baffle 3. This design allows the lava bottle 1 to be stably installed on the light source base 4, while the heat source baffle 3 can effectively support the heating head 2, ensuring that the heating head 2 is in close contact with the heat source mounting groove 11 at the bottom of the lava bottle 1, thereby improving heat conduction efficiency.

[0046] The light source holder 4 includes a base 41 and a straight-through cup 42 with openings at both ends, which is connected to the base 41. The straight-through cup 42 is threadedly connected to the base 41. The light-emitting element 5 is installed inside the base 41, and an annular support platform 421 is provided on the inner wall of the straight-through cup 42. The separate design of the base 41 and the straight-through cup 42 facilitates the installation of the light-emitting element 5, which can illuminate the lava bottle 1 from below. The open design at both ends of the straight-through cup 42 facilitates the installation and maintenance of the lava bottle 1.

[0047] A light source mounting platform 51 is installed inside the base 41. The light-emitting element 5 is an LED light source board, which is installed inside the light source mounting platform 51. The light source mounting platform 51 is composed of an insulating platform and a heat-conducting metal platform stacked together.

[0048] The lava lamp also includes a counterweight base 6, such as Figure 6 , 7 As shown, the light source base 4 is directly mounted on the counterweight base 6. A first threaded post is installed through the counterweight base 6 and the base body 41. One end of the first threaded post, penetrating the counterweight base 6, is fixed by a first nut, and the other end, penetrating the base body 41, is fixed by a second nut. The second nut is a double-ended nut, including nut structures at both ends. One end of the threaded post, penetrating the base body 41, is connected to the lower nut structure of the double-ended nut. The light source mounting platform 51 is supported on the upper end of the double-ended nut. A second threaded post is installed through the light source mounting platform 51. The upper end of the second threaded post, penetrating above the light-emitting element 5, is locked by a third nut. The lower end of the third nut abuts against the light-emitting element 5, fixing the light-emitting element 5. The lower end of the second threaded post is connected to the upper nut structure of the double-ended nut, thus fixing the light source mounting platform 51 inside the base body 41. Both the first and second threaded posts are hollow. The wires that are electrically connected to the PTC heating element and the wires that are electrically connected to the light-emitting element 5 extend from the inner cavity of the first and second threaded posts to the counterweight base 6 and are electrically connected to the power cord 7 connected to the counterweight base 6.

[0049] In other embodiments, the light source holder is indirectly mounted on the counterweight base via a support member. For example... Figure 8 , 9As shown, the light source base 4 is indirectly mounted on the counterweight base 6 via the support rod 8.

[0050] The counterweight base 6 increases the stability of the entire lamp, preventing instability of the center of gravity caused by the height of the lava bottle, and ensuring that the lamp is not easy to tip over during use.

[0051] In use, the light emitted by the light-emitting element 5 shines through the empty area 33 on the heat source baffle 3 onto the lava bottle 1. At the same time, the heating head 2 heats the bottom of the lava bottle 1, causing the waxy substance inside to melt and create a flowing effect. The light passes through the lava bottle 1, illuminating the flowing lava and creating a captivating visual effect.

[0052] This lava lamp achieves stable structural support and efficient heating by rationally designing the relative positions of the light source holder, lava bottle, and heating structure, while ensuring good lighting effects and enabling the lava lamp to present an aesthetically pleasing visual effect.

[0053] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the contents of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
