Detailed Implementation

[0029] The present invention will now be described in detail with reference to specific embodiments and accompanying drawings.

[0030] Please see Figures 1 to 7 This paper illustrates an intelligent temperature-controlled energy-saving lava lamp 100, comprising an intelligent control module 50, a lamp tube body 10, a heating component, a temperature control component, and a light source component 40. The heating component, the temperature control component, and the light source component 40 are located below the lamp tube body 10. The lamp tube body 10 includes an inner glass tube 11 and an outer heat insulation tube 12. The outer heat insulation tube 12 is sleeved on the outside of the inner glass tube 11. The inner glass tube 11 is filled with a transparent liquid 16 and an ornamental wax 17. The intelligent control module 50 is used to control the heating component, the temperature control component, and the light source component to heat the solidified wax 17 inside the inner glass tube 11. After the wax 17 melts, it forms a wax ball that can float up and down inside the inner glass tube 11. The heating assembly includes a heating element 21 and a heat-conducting cup 22, used to heat the wax 17 that has solidified inside the inner glass tube 11; The temperature control component includes a temperature control probe 31, which is 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. The light source assembly includes a central light source 41 and a peripheral light source 42. The peripheral light source 42 surrounds the outside of the central light source 41. The light source assembly is located below the heating assembly and illuminates the lamp tube body 10, making the lamp tube body 10 completely transparent.

[0031] Preferably, the inner glass tube 11 has a closed bottom surface, and an annular spring 13 is provided inside the inner glass tube 11. The annular spring 13 is located at the bottom inner side of the inner glass tube 11. The inner glass tube 11 contains the transparent liquid 16 and the wax 17.

[0032] Specifically, the bottom end of the inner glass tube 11 is completely sealed. In this embodiment, the transparent liquid 16 inside the inner glass tube 11 is preferably pure water. The wax 17 is solid at room temperature and condenses at the bottom of the inner glass tube 11 to form a columnar wax. After being heated to a predetermined temperature, the wax 17 melts into a liquid state, forming a wax ball that floats up and down under the influence of the transparent liquid 16.

[0033] Preferably, the heat-conducting cup 22 is fitted onto the bottom end of the inner glass tube 11, and the heating element 21 is disposed between the bottom of the inner glass tube 11 and the bottom surface of the heat-conducting cup 22. The bottom surface of the heat-conducting cup 22 has a recessed step 222 for accommodating the heating element 21. The top and bottom surfaces of the heating element 21 are coated with thermally conductive silicone grease. 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 sidewalls and bottom surface of the heat-conducting cup 22 are tightly fitted to the outer sidewalls and bottom of the inner glass tube 11 to rapidly heat and melt the solidified wax 17.

[0034] Specifically, the top and bottom surfaces of the heating element 21 are coated with thermally conductive silicone grease to increase the heat conduction efficiency between the heating element 21 and the heat-conducting cup 22. The heating element 21 is wrapped between the inner glass tube 11 and the heat-conducting cup 22, directly conducting heat to 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 peripheral surface of the recessed step 222 is in close contact with the bottom surface of the inner glass tube 11, increasing the contact area between the heat-conducting cup 22 and the inner glass tube 11, allowing heat to be quickly 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. This allows the top wax to break through quickly and heats the transparent liquid 16 and wax 17 more quickly, shortening the time it takes for the wax 17 to float and the wax ball to rise. This avoids the long waiting time common in existing lava lamps.

[0035] Preferably, the heat-conducting cup 22 has a detection hole 224 near the top of its sidewall, and the temperature-sensing end 311 of the temperature control probe 31 extends into the detection hole 224 and fits tightly against the sidewall of the inner glass tube 11; the detection hole 224 is larger than the temperature-sensing end 311 of the temperature control probe 31 to avoid the temperature-sensing end 311 of the temperature control probe 31 from contacting the sidewall of the heat-conducting cup 22; the temperature control probe 31 is electrically connected to the intelligent control module 50.

[0036] Specifically, 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.

[0037] Preferably, the central light source 41 uses high-power LED beads, and the peripheral light source 42 uses multiple low-power LED beads, which are arranged around the high-power LED beads.

[0038] Preferably, the heating element 21 and the heat-conducting cup 22 have a central hole 221 at the bottom center, and the heat-conducting cup 22 has a plurality of light-transmitting holes 223 around the bottom. The size, position and number of the central hole 221 and the plurality of light-transmitting holes 223 correspond to the size, position and number of the LED beads of the central light source 41 and the peripheral light source 42.

[0039] Specifically, the light source assembly 40 is provided with heat insulation cotton on the upper and lower sides to 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, and extending the lifespan of the lamp beads.

[0040] Specifically, the first heat insulation cotton 60 is disposed above the light source assembly 40, and the second heat insulation cotton 70 is disposed below the light source assembly 40. The first heat insulation cotton 60 has a central hole and multiple light-transmitting holes, which correspond to the central hole 221 and multiple light-transmitting holes 223 on the bottom surface of the heat-conducting cup 20, respectively.

[0041] Specifically, the lava lamp also includes a PCB circuit board, on which the intelligent control module 50 and the related circuits of the temperature control component and the heating component are all disposed; the PCB circuit board is located below the light source component 40 and the second heat insulation cotton 70.

[0042] Preferably, please refer to Figure 8 The intelligent control module 50 includes a main control unit U2, wherein, The DAT pin of the main control unit U2 is connected to the infrared remote control receiver module to receive control signals sent by the remote controller. The PWM-W pin and DO pin of the main control unit U2 are connected to the light source assembly and are used to control the color and brightness of the central light source 41 and the peripheral light source 42. The NTC-ADC pin of the main control unit U2 is connected to the temperature control probe 31, and is used to receive the temperature value monitored by the temperature control probe 31 and perform analog-to-digital conversion. The PWM-PTC pin of the main control unit U2 is connected to the control unit of the heating element 21, and is used to control the temperature of the transparent liquid 16 and wax 17 in the inner glass tube 11 by adjusting the output power of the heating element 21. The DAT and TXD pins of the main control unit U2 are connected to the download interface to establish a communication connection with the external debugging device, so as to realize the functional debugging of the intelligent control module 50.

[0043] Preferably, please refer to Figure 9 The heating element 21 control unit includes a first switching transistor Q1. The gate of the first switching transistor Q1 is connected to the PWM-PTC pin of the main control unit through a ninth resistor R9. The source of the first switching transistor Q1 is grounded, and the drain of the first switching transistor Q1 is connected to the connector CN2. The connector CN2 is used to connect the heating element 21.

[0044] Specifically, pin 1 of the connector CN2 is connected to the power supply VDD, and pin 2 of the connector CN2 is connected to the drain of the first switching transistor Q1.

[0045] Specifically, the main control unit U2 controls the output power of the heating element 21 by changing the duration of the PWM-PTC pulse signal. When the PWM-PTC pin outputs a high level, the first switch Q1 is turned on, and the heating element 21 is connected to the power supply and starts heating. When the PWM-PTC pin outputs a low level, the first switch Q1 is turned off, and the heating element 21 is disconnected from the power supply and stops heating.

[0046] Specifically, the duration of the PWM-PTC pulse signal varies at different times after the lava lamp starts working, and the output power of the heating element 21 changes accordingly. In this embodiment, during the first time period (3-5 minutes), the heating component gradually heats the lamp tube body 10 to prevent the glass lamp tube from cracking due to sudden heating. The peripheral light source 42 illuminates the outer wall of the lamp tube body 10, making the lamp tube body 10 bright.

[0047] During the second time period (40-45 minutes), the heating component steadily heats the lamp tube body 10, causing the solid wax 17 inside the inner glass tube 11 to melt. The bottom of the solid wax 17 begins to melt first. The density of the melted wax 17 is less than that of the transparent liquid 16, causing the melted wax 17 to move upwards. Before the top surface of the solid wax 17 is completely melted, the melted wax 17 breaks through the top surface of the solid wax 17, forming a lava eruption state of the wax 17. As the melted wax 17 rises, the temperature of the transparent liquid 16 decreases, causing the melted wax 17 to re-condense and fall.

[0048] During the third time period (45 minutes to 6 hours), the output power of the heating component is stabilized at a predetermined lower output value, and the temperature control component monitors the temperature of the lamp body 10, keeping the temperature of the lamp body 10 stable at 48~56 degrees Celsius. The solid wax 17 completely melts, and the melted wax 17 forms a wax ball that moves up and down inside the lamp body 10. The central light source 41 illuminates the center of the lamp body 10, making the lamp body 10 appear crystal clear.

[0049] After the lava lamp has been working for 6 to 10 hours, the intelligent control module 50 automatically cuts off the power supply to prevent the lava lamp from working for a long time, which would affect the floating state of the wax ball, and at the same time avoid heat accumulation, which would cause the performance of the heating component, temperature control component and light source component to degrade.

[0050] Specifically, please refer to Figure 10 The temperature control probe 31 is plugged into interface CN3 and connected to the NTC-ADC pin of the main control unit U2 via pin 2.

[0051] Preferably, the light source assembly further includes an RGB control unit U3, see [link to relevant documentation]. Figure 11 The RGB control unit U3 includes three independent control channels. The central light source 41 uses high-power RGB LED beads. The three independent control channels of the RGB control unit U3 are respectively connected to the three independent light-emitting chips of the high-power RGB LED beads through a switching transistor. The RGB control unit U3 changes the brightness ratio of the three independent light-emitting chips to make the high-power RGB LED beads present different colors and brightness.

[0052] Specifically, in this embodiment, the central light source 41 uses high-power LED beads, and the peripheral light source 42 uses multiple low-power LED beads, which are arranged around the high-power LED beads.

[0053] Specifically, the RGB control unit U3 uses the WS2811 chip, which is a three-channel LED driver chip that integrates control circuitry and constant current drive. By receiving a specific digital signal, it decodes the target color information and uses it to control the brightness and color of the RGB LED beads, thereby achieving the effect that each LED bead can be programmed independently.

[0054] Specifically, the DIN pin of the RGB control unit U3 is connected to the light source output control pin of the main control unit U2, and the OUTR pin, OUTG pin, and OURB pin of the RGB control unit U3 are respectively connected to three independent LED chips in the RGB LED beads. The brightness of each color channel is controlled by PWM technology to achieve precise adjustment from 0 to 255 levels.

[0055] Specifically, the DO pin of the main control unit U2 is used to control the RGB light source, and the PWM-W pin of the main control unit U2 is used to control the monochromatic light source. When the light source assembly is used for RGB light source control, the DO pin of the main control unit U2 is connected to the DIN pin of the RGB control unit U3. When the light source assembly is used for monochromatic light (e.g., white light, red light, green light), the PWM-W pin of the main control unit U2 is connected to the DIN pin of the RGB control unit U3.

[0056] Specifically, please refer to Figure 12 The peripheral light source 42 consists of multiple low-power LEDs connected in series, with each low-power LED connected sequentially. The DOUT pin of one low-power LED is connected to the DIN pin of the next low-power LED. These low-power LEDs are connected to the DIN pin of the RGB control unit U3 via current-limiting resistors R7 and R8, and the RGB control unit U3 controls the on / off state of the peripheral light source 42.

[0057] Preferably, the lava lamp also includes a power module; please refer to [link / reference]. Figure 13 The power module includes an adapter unit and a DC-DC converter unit. The adapter unit is used to convert AC mains power into a 24V voltage source. The output terminal of the adapter unit is connected to the DC-DC converter unit. The DC-DC converter unit is used to convert the 24V voltage source into a 5V voltage source to provide working power for the intelligent control module 50, the heating component, the temperature control component, and the light source component.

[0058] Specifically, the DC-DC conversion unit includes a power management unit U1, which uses an HI9001 chip. The HI9001 chip is a synchronous buck power management chip with high integration, a wide input voltage range, and multiple protection functions. Its input voltage range is 4.5V to 36V, compatible with mainstream applications such as lithium batteries, automotive power supplies, and industrial bus voltages. It provides a continuous output current of up to 2A and uses a COT (Constant On Time) control mode for rapid dynamic response and stable output voltage during load changes. In this embodiment, the output voltage of the power management unit U1 is 5V. The output terminal of the power management unit U1 is connected to the main control unit U2, the control unit of the heating element 21, the temperature detection unit of the temperature control probe 31, and the power input terminal of the power supply assembly.

[0059] Specifically, the lava lamp operates at a safe voltage of 24V, which is lower than the human body's safe voltage threshold. It will not cause harm when children touch it, thus improving the safety of the product.

[0060] In the aforementioned intelligent temperature-controlled energy-saving lava lamp, the heating element and the heat-conducting cup are wrapped around the end of the inner glass tube, providing heat to the lamp body to melt solid wax. The light source assembly is used to illuminate the lamp body to enhance the aesthetics of the lava lamp. The intelligent control module controls the heating assembly, the temperature control assembly, and the light source assembly to maintain a constant internal temperature of the lamp body during operation, stabilizing it at a low temperature sufficient for wax melting, thus achieving intelligent temperature control. Simultaneously, it reduces the output power of the heating element, thereby lowering the energy consumption of the lava lamp. This invention has a simple structure, is easy to implement, safe and reliable, has low overall cost, and is easy to promote.

[0061] It should be noted that this utility model is not limited to the above-described embodiments.
