Description

Technical Field

[0001] This invention relates to the field of lighting technology, specifically to a double-layer heat-insulated intelligent temperature-controlled integrated lava lamp and its control method. Background Technology

[0002] Lava lamps are made by filling a sealed glass bottle with a transparent liquid and wax, and then heating it at the base. The glass bottle appears to be filled with flowing lava, creating a mesmerizing effect of moving and changing light and shadow using physical principles. It is a globally popular indoor mood lighting solution.

[0003] Existing lava lamps use a detachable structure for the glass tube and lamp base. An incandescent or halogen lamp is installed inside the lamp base to continuously heat the glass tube in a non-contact manner. Due to the limited heat conduction performance, the heating time is long, the energy consumption is high, and the efficiency is low. At the same time, the detachable structure exposes the heating components directly, which can be touched by fingers and easily cause burns.

[0004] Lava lamps, which create light and shadow effects by heating wax and illuminating it, easily attract children's interest. However, lava lamps need to maintain a high temperature for extended periods during operation; the temperature inside the heating chamber often exceeds 200 degrees Celsius, and the lamp body exceeds 55 degrees Celsius. Although there are disclaimers on the outer wall of the lava lamp stating "Extremely hot! Don't touch while operating," children or pets may not pay attention to these warnings. Driven by curiosity, children may directly touch the heating element, resulting in severe burns. Even without noticing the warning label, touching the lamp still poses an extremely high risk of burning hands and causing fright. Summary of the Invention

Detailed Implementation

[0046] This embodiment takes a double-layer heat-insulated intelligent temperature-controlled integrated lava lamp and its control method as an example. The invention will be described in detail below with reference to specific embodiments and accompanying drawings.

[0047] Please see Figures 1 to 11 This illustration shows a double-layer heat-insulated intelligent temperature-controlled integrated lava lamp 100 provided by an embodiment of the present invention, including a lamp tube body 10, a heating component, a temperature control component, and a light source component 40, wherein the heating component, the temperature control component, and the light source component 40 are disposed at the bottom of the lamp tube body 10; wherein,

[0048] The lamp tube body 10 includes an inner glass tube 11 and an outer heat insulation tube 12. The inner glass tube 11 is filled with a transparent liquid 16 and an ornamental wax 17. The wax 17 melts when heated to form a wax ball that can float up and down inside the inner glass tube 11. The outer heat insulation tube 12 is sleeved on the outside of the inner glass tube 11 to block the internal heat transfer and prevent people from being burned.

[0049] The heating component is located below the inner glass tube 11 and is used to heat the wax 17 inside the inner glass tube 11.

[0050] The temperature control component includes a temperature control probe 31 and a temperature control module, used to monitor and control the temperature of the inner glass tube 11, so that the temperature value of the inner glass tube 11 is stable within a predetermined range.

[0051] The light source assembly 40 includes a central light source 41 and peripheral light sources 42. Please refer to [link / reference]. Figure 11 The peripheral light source 42 surrounds the outside of the central light source 41, and the light source assembly 40 is located below the heating assembly and illuminates the lamp tube body 10, making the lamp tube body 10 completely transparent.

[0052] Preferably, the inner glass tube 11 has a closed bottom surface and an upward opening, and an annular spring 13 is provided inside the inner glass tube 11, the annular spring 13 being located at the inner bottom of the inner glass tube 11; the outer heat insulation tube 12 is a transparent tube, the outer heat insulation tube 12 and the inner glass tube 11 are coaxially arranged, and there is a predetermined gap between the outer heat insulation tube 12 and the sidewall of the inner glass tube 11.

[0053] Specifically, the bottom end of the inner glass tube 11 is completely sealed, and the heated transparent liquid 16 and wax 17 are contained inside the inner glass tube 11. The air between the outer heat insulation tube 12 and the inner glass tube 11 allows the outer heat insulation tube 12 to play a good heat insulation role.

[0054] Specifically, the lamp tube body 10 ensures that the temperature inside the inner glass tube 11 is not easily lost, resulting in good heat preservation. When the wax ball floats normally, the lava lamp enters the intelligent temperature control and heat preservation stage, requiring only extremely low power heating to compensate for heat loss, allowing the lava lamp to be lit for a long time and saving energy.

[0055] Specifically, in this embodiment, the transparent liquid 16 is preferably pure water, and the wax 17 is solid at room temperature and condenses at the bottom of the inner glass tube 11 to form columnar wax 17. After being heated to a predetermined temperature, the wax 17 melts into a liquid state, forming wax balls that float up and down in the transparent liquid 16.

[0056] Specifically, the lamp tube body 10 can also effectively prevent the external environment from affecting the transparent liquid 16 and wax 17 inside the inner glass tube 11. During transportation, the high temperature inside the container may cause the wax 17 inside the glass tube to melt, affecting the clarity of the transparent liquid 16.

[0057] Specifically, the annular spring 13 is located at the bottom of the inner glass tube 11, allowing the wax ball to re-fuse at the bottom of the inner glass tube 11, creating a more natural flow effect.

[0058] Specifically, in this embodiment, the inner glass tube 11 and the outer heat insulation tube 12 are preferably high borosilicate glass. High borosilicate glass has the advantages of extremely low coefficient of thermal expansion, strong thermal shock resistance, corrosion resistance, high light transmittance and high cleanliness. It is not easily broken by sudden temperature changes and has strong chemical stability, which makes the lamp tube body 10 have a longer service life and better light transmittance.

[0059] Specifically, the outer heat insulation tube 12 can be made of glass or plastic.

[0060] Preferably, the lamp body 10 further includes a top cover 15, see [link to relevant documentation]. Figure 5 and Figure 6 The top cover 15 has a circular sidewall surrounding the perimeter, and the top end sidewall of the outer heat insulation tube 12 abuts against the inner sidewall of the top cover 15; the top cover 15 has a raised frustum 153 in the center of the interior, the outer sidewall of the frustum 153 has an external thread, the inner sidewall of the inner glass tube 11 has an internal thread near the top end, and the top end of the inner glass tube 11 is threadedly connected to the inner frustum 153 of the top cover 15;

[0061] The bottom surface of the truncated cone 153 facing the inner glass tube 11 is a polished mirror surface to reflect the light emitted by the light source assembly 40, so that there are no dark areas inside the lamp tube body 10 and the top of the wax ball, making the whole thing crystal clear.

[0062] Specifically, the top surface of the top cover 15 has a boss 151, the diameter of the truncated cone 153 is smaller than the diameter of the boss 151, the truncated cone 153 is located in the center of the boss 151, there is a gap between the inner side wall of the boss 151 and the outer side wall of the truncated cone 153, the inner glass tube 11 has an internal thread on the inner side of its top end, the truncated cone 153 has an external thread, the inner glass tube 11 is threaded onto the truncated cone 153, and the top end of the inner glass tube 11 is provided with a sealing gasket 14, preferably made of silicone, to increase the sealing between the top cover 15 and the inner glass tube 11 and prevent the transparent liquid 16 inside the inner glass tube 11 from leaking out.

[0063] Specifically, on the top surface of the top cover 15, the boss 151 has an annular edge 152 around it, and the top end of the outer heat insulation tube 12 abuts against the inner side of the annular edge 152, so that the interval between the outer heat insulation tube 12 and the inner glass tube 11 corresponds to the width of the annular edge 152.

[0064] Specifically, the bottom surface of the top cover 15 is in contact with the transparent liquid 16 inside the inner glass tube 11, giving the top cover 15 a certain heat dissipation function. Due to the heat dissipation function of the top cover 15, the temperature of the transparent liquid 16 at the top of the inner glass tube 11 is lower than the temperature of the transparent liquid 16 at the bottom.

[0065] Preferably, the heating assembly includes a heating element 21, a heat-conducting cup 22, and a heating control module. The heat-conducting cup 22 is fitted onto the bottom end of the inner glass tube 11, and the height of the heat-conducting cup 22 is at least two-thirds greater than the height of the solidified wax 17 inside the inner glass tube 11. The heating element 21 is attached between the outer bottom of the inner glass tube 11 and the inner bottom of the heat-conducting cup 22. The top and bottom surfaces of the heating element 21 are coated with thermally conductive silicone grease to improve thermal conductivity. The heating element 21 is in the shape of a thick ring, has a first central hole 211, and has a connecting wire connected to the heating control module.

[0066] Preferably, please refer to Figure 9 The bottom center of the heat-conducting cup 22 has a recessed step 222, the recessed height of which is adapted to the thickness of the heating element 21, and the heating element 21 is disposed within the recessed step 222.

[0067] The bottom center of the sunken step 222 has a second central hole 221, which corresponds to the size and position of the first central hole 211. The outer periphery of the sunken step 222 is provided with a plurality of first light-transmitting holes 223. The size and position of the first central hole 211 and the second central hole 221 correspond to the size and position of the central light source 41, and the number and position of the first light-transmitting holes 223 correspond to the number and position of the LED beads of the peripheral light source 42.

[0068] Specifically, the heat-conducting cup 22 has a U-shaped cross-section and is wrapped around the end of the inner glass tube 11. The side wall of the heat-conducting cup 22 extends between the side wall of the inner glass tube 11 and the side wall of the outer heat insulation tube 12, and is tightly fitted with the outer side wall of the inner glass tube 11 to conduct the heat generated by the heating element 21 to the inner glass tube 11.

[0069] Specifically, the heating element 21 is wrapped between the inner glass tube 11 and the heat-conducting cup 22, directly conducting heat to both the inner glass tube 11 and the heat-conducting cup 22, resulting in more efficient heating. On the bottom surface of the heat-conducting cup 22, the outer circumferential surface of the recessed step 222 is in close contact with the bottom surface of the inner glass tube 11. By increasing the contact area between the heat-conducting cup 22 and the inner glass tube 11, heat is rapidly conducted to the inner glass tube 11. Meanwhile, the sidewall of the heat-conducting cup 22 has a predetermined height. The height of the heat-conducting cup 22 is greater than two-thirds of the height of the solidified wax 17 inside the inner glass tube 11, and less than the height of the solidified wax 17. This allows most of the solidified wax 17 to be enclosed by the heat-conducting cup 22. The heating element 21 and the heat-conducting cup 22 simultaneously heat the bottom and surrounding area of ​​the solidified wax 17, which can quickly melt the entire solidified wax 17, allowing the top wax to break through quickly, and quickly heating the transparent liquid 16 and the wax 17. This shortens the time required to trigger the wax 17 to float and the wax ball to float, avoiding the long waiting time common in existing lava lamps.

[0070] Specifically, the light source assembly 40 is located below the heat-conducting cup 22. The light from the peripheral light source 42 needs to pass through the first light-transmitting holes 223 at the bottom of the heat-conducting cup 22, and the light from the central light source 41 needs to pass through the second central hole 221 at the bottom of the heat-conducting cup 22 and the first central hole 211 of the heating plate 21. Before the solid wax 17 melts, the light from the central light source 41 is blocked by the solid wax 17, and the light from the peripheral light source 42 shines on the side wall of the inner glass tube 11, making the lamp tube body 10 appear bright and transparent before the solid wax 17 melts. After the solid wax 17 melts, the light from the central light source 41 illuminates the inside of the inner glass tube 11. At the same time, the light reflected and refracted by the side wall of the inner glass tube 11 and the top cover 15 makes the transparent liquid 16 and the melted wax ball inside the lamp tube body 10 appear bright and transparent.

[0071] Specifically, the top edge 225 of the sidewall of the heat-conducting cup 22 divides the space between the inner glass tube 11 and the outer heat insulation tube 12 into two parts, which can reduce the upward diffusion of heat generated by the sidewall of the heat-conducting cup 22.

[0072] Specifically, the gap between the edge 225 and the inner wall of the outer heat insulation tube 12 can prevent the air between the inner glass tube 11 and the outer heat insulation tube 12 from being subjected to excessive air pressure when the air between the inner glass tube 11 and the outer heat insulation tube 12 expands and contracts with temperature.

[0073] Preferably, the heat-conducting cup 22 has a detection hole 224 near the top of its side wall, and the temperature sensing end 311 of the temperature control probe 31 extends into the detection hole 224 and is tightly fitted to the side wall of the inner glass tube 11; the temperature control probe 31 is electrically connected to the temperature control module.

[0074] Specifically, the detection hole 224 on the side wall of the heat-conducting cup 22 is larger than the temperature sensing end 311 of the temperature control probe 31. The temperature sensing end 311 of the temperature control probe 31 extends into the detection hole 224, while avoiding contact between the temperature sensing end 311 of the temperature control probe 31 and the side wall of the heat-conducting cup 22. The temperature sensing end 311 of the temperature control probe 31 is attached to the side wall of the inner glass tube 11 with thermally conductive adhesive, so that the temperature control probe 31 can directly detect the temperature of the cup body of the inner glass tube 11.

[0075] Preferably, the light source assembly 40 is provided with a first heat insulation cotton 60 and a second heat insulation cotton 70 on its upper and lower sides, respectively. The first heat insulation cotton 60 is located above the light source assembly 40 and has a third central hole 61 corresponding to the central light source 41. The first heat insulation cotton 60 also has a plurality of second light-transmitting holes 62 corresponding to the peripheral light source 42. The second heat insulation cotton 70 is located below the light source assembly 40.

[0076] Specifically, please refer to Figure 10 The size and position of the third central hole 61 of the first heat insulation cotton 60 correspond to the size and position of the first central hole 211 and the second central hole 221, so that the light from the central light source 41 illuminates the bottom center of the inner glass tube 11; the number and position of the second light-transmitting holes 62 of the first heat insulation cotton 60 correspond to the number and position of the first light-transmitting holes 223, so that the light from the peripheral light source 42 illuminates the side wall of the inner glass tube 11.

[0077] Specifically, the first heat insulation cotton 60 can prevent the heat generated by the heating element 21 and the heat-conducting cup 22 from spreading downwards, protecting the lamp beads of the central light source 41 and the peripheral light source 42 from being below 65°C, avoiding excessive local temperature of the lamp beads leading to light and color decay, extending the lifespan of the lamp beads, and preventing the incandescent or halogen lamps in existing lava lamps from being damaged due to overheating and having a bulb lifespan of less than 2000 hours.

[0078] Preferably, the lava lamp further includes a remote control receiving module and an intelligent control circuit board 50. The remote control receiving module is used to receive control signals from a remote controller to adjust the color and brightness of the central light source 41 and the peripheral light source 42. The temperature control module, the heating control module, and the remote control receiving module are disposed on the intelligent control circuit board 50. The intelligent control circuit board 50 is disposed below the second heat insulation cotton 70.

[0079] Specifically, in this embodiment, the remote control receiving module uses RGB control technology to mix different colors by adjusting the brightness ratio of the three primary colors: red, green, and blue. The RGB LED consists of three independent LED chips, and the brightness of each color channel is controlled by PWM technology to achieve precise adjustment from 0 to 255 levels.

[0080] Preferably, the lava lamp also includes a bottom housing 86, see [link to relevant documentation]. Figure 7 and Figure 8 The bottom housing 86 is located below the lamp tube body 10, and the heating component, the temperature control component, and the light source component 40 are located inside the bottom housing 86.

[0081] The inner sidewall of the bottom housing 86 has a raised step 861 near the top, and the bottom end of the outer heat insulation tube 12 abuts against the step 861.

[0082] The top of the sidewall of the heat-conducting cup 22 has an outwardly extending edge 225. The edge 225 extends from the outer sidewall of the inner glass tube 11 to the inner sidewall of the outer heat insulation tube 12. The edge 225 is located at the edge of the step 861, and there is a gap between the edge 225 and the inner sidewall of the outer heat insulation tube 12.

[0083] The bottom surface 862 of the bottom housing 86 is provided with a toothed tube 87 in the center. The toothed tube 87 is used to connect the bottom housing 86 and the base. The base has a predetermined counterweight to make the lava lamp stable.

[0084] Specifically, in this embodiment, the bottom housing 86 is preferably made of metal to conduct the heat generated by the heating component, the temperature control component, and the light source component 40 into the air, thereby preventing the components of the heating component, the temperature control component, and the light source component 40 from overheating.

[0085] Specifically, the annular edge 152 of the top surface of the top cover 15 and the step on the inner side of the bottom shell 86 are respectively located at the top and bottom of the outer heat insulation tube 12 to fix the outer heat insulation tube 12. The top part of the bottom shell 86 is adhered to the outer heat insulation tube 12, so that the lamp body 10 is fixedly connected to the bottom shell 86 and cannot be separated, thus preventing the heating element 21 from being exposed after the lamp body 10 is removed, which could cause burns to personnel. At the same time, the step 861 on the inner side of the bottom shell 86 is a stop and fixing position for the outer heat insulation tube 12 and the heat conducting cup 22. There is a gap between the edge 225 of the heat conducting cup 22 and the inner wall of the outer heat insulation tube 12, so that the bottom shell 86 is in direct contact with the outer heat insulation tube 12, but not with the inner glass tube 11 and the heating element 21, which can prevent the temperature of the bottom shell 86 from becoming too high.

[0086] Specifically, the top cover 15 adopts a double-layered, airtight structure. There is a heat-insulating gap between the outer heat-insulating tube 12 and the inner glass tube 11, and a sealing gasket 14 is provided between the inner glass tube 11 and the top cover 15. The sealing gasket 14 has a sealing and heat-insulating function, preventing the top cover 15 from overheating. Additionally, a glass cover (not shown) can be installed on top of the lava lamp, covering the top cover 15 to further enhance the heat insulation effect.

[0087] Specifically, when the lava lamp is working normally, the transparent liquid 16 inside the inner glass tube 11 is stably maintained between 48 and 56 degrees Celsius, so that the temperature of the outer heat insulation tube 12 is close to the human body temperature. Therefore, the use of the outer heat insulation tube 12 can prevent people from being burned by touching the lava lamp. At the same time, it keeps the temperature of the glass cover and the bottom shell 86 within a safe range.

[0088] Specifically, in other embodiments, the bottom housing 86 and the glass cover on top of the lava lamp are fitted with structural components made of metal or plastic to prevent the glass tube from breaking due to impact when tilted.

[0089] And, please see Figure 12 This paper presents a control method for a double-layer heat-insulated intelligent temperature-controlled integrated lava lamp, used to control the operation of the double-layer heat-insulated intelligent temperature-controlled integrated lava lamp as described in any of the preceding claims. The specific steps of the control method include:

[0090] After the lava lamp is assembled, connect it to the power supply;

[0091] During the first time period T1, the output power of the heating control module gradually increases from 0 to the maximum power value;

[0092] During the second time period T2, the output power of the heating control module stabilizes at its maximum power.

[0093] During the third time period T3, the output power of the heating control module drops to a predetermined value, and the temperature control component monitors the temperature of the lamp body to keep the temperature of the lamp body stable within a predetermined range.

[0094] After the fourth time period T4, the power is cut off and the lava lamp stops working.

[0095] Specifically, in this embodiment, the first time period T1 lasts for 3 to 5 minutes. The heating control module gradually heats the lamp tube body to prevent the glass lamp tube from cracking due to sudden heating. The peripheral light source illuminates the outer wall of the lamp tube body, making the lamp tube body bright.

[0096] The second time period, T2, lasts 40-45 minutes. During this period, the heating control module steadily heats the lamp body, melting the solid wax inside the inner glass tube. The bottom of the solid wax melts first. Since the density of the melted wax is less than that of the transparent liquid, it rises. Before the top surface of the solid wax is completely melted, the melted wax breaks through the top surface, creating a lava eruption effect. As the melted wax rises, the temperature of the transparent liquid decreases, causing the melted wax to re-condense and fall back down.

[0097] The third time period, T3, lasts from 45 minutes to 6 hours. During this period, the output power of the heating control module remains stable at a predetermined minimum value. The temperature control component monitors the temperature of the lamp body, maintaining it between 48 and 56 degrees Celsius. The solid wax completely melts, forming wax balls that move up and down within the lamp body. The central light source illuminates the center of the lamp body, giving it a crystal-clear appearance.

[0098] The fourth time period, T4, lasts for 6 to 10 hours. After the lava lamp has been in operation for the predetermined time, the power can be automatically cut off to prevent the lava lamp from working for a long time, which could affect the floating state of the wax ball and avoid heat accumulation that could cause a decline in the performance of the heating components, temperature control components, and light source components.

[0099] In the aforementioned double-layer heat-insulated intelligent temperature-controlled integrated lava lamp and its control method, the heating component rapidly heats the transparent liquid and wax inside the lamp tube body, causing the wax to melt quickly and form wax balls that float up and down inside the lamp tube. The temperature control component monitors the temperature of the lamp tube body, and the heating component maintains the lava lamp's normal operation with a lower output power. The lamp tube body adopts a double-layer heat-insulating structure, effectively blocking the heat from the inner glass tube to the outside, improving the thermal efficiency of the heating component, and shortening the preheating time of the lava lamp. Simultaneously, the lamp tube body is fixedly installed to the bottom shell, eliminating safety hazards. The method of this invention is simple, easy to implement, safe and reliable, has low overall cost, and is easy to promote.

[0100] It should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention can be modified and varied in various ways. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of the present invention should be included within the scope of protection of the present invention.
