Description

Technical Field

[0001] The utility model relates to the field of candles, in particular to a temperature-sensitive luminous candle cup lamp. Background Art

[0002] At present, candles and lamps are no longer just used for lighting, but are also used for decoration. Candlelight and lights can be combined to achieve a more beautiful effect, especially for scented candles, which often add light decorations to enhance the atmosphere.

[0003] For example, the patent application number CN202221496629.6 is a reusable photosensitive aromatherapy candle. When the wick is lit, the light guide transmits the light generated by the burning wick to the light sensor, causing the light sensor to close, so that the light-emitting component is powered and emits light. However, there are the following problems: 1) Using light guides such as optical fibers will significantly increase costs; 2) If the light guide is opposite to strong light such as sunlight or lamplight, the light string will also light up, causing waste; 3) If the candle burns for a while and the wick moves downward, it will be difficult to align with the light guide, causing the light string to not light up; 4) When the lighter has not completely ignited the wick, the flame of the lighter will also be transmitted to the light sensor, and the light string will light up before the candle, resulting in a weak sense of interaction.

[0004] Another example is a temperature-sensing aromatherapy candle atmosphere lamp with patent application number CN202221962842.1. It uses a temperature sensor to sense the temperature to control the opening and closing of the lamp. However, the temperature sensor is directly set on the side above the inner cup wall, which has the following problems: 1) When the candle burns unevenly, the temperature on one side is high and the temperature on the other side is low. If the temperature sensor happens to be on the side with low temperature, the lamp cannot be controlled to light up; 2) After the candle burns for a while, the flame position moves downward, and the temperature sensor cannot receive the flame temperature, causing the lamp to go out; 3) The temperature sensor is easily damaged by long-term exposure to the high temperature caused by the fire. Utility Model Content

[0005] In response to the shortcomings of the existing technology, the purpose of the utility model is to provide a temperature-sensitive luminous candle cup lamp, which adopts a spiral heat conductor to ensure that the lamp is on regardless of whether the candle burns evenly or not. Within a short time after the candle is lit, the light-emitting part can gradually light up, giving people a sense of interaction. The combination of candlelight and light produces a beautiful effect. It is low-cost and not easy to damage.

[0006] The utility model provides a temperature-sensitive luminous candle cup lamp, comprising an outer cup, an inner cup, a candle, a heat-conducting wire, a thermistor, a battery pack and a light-emitting component, wherein the inner cup is arranged inside the outer cup, the candle is arranged inside the inner cup, the heat-conducting wire is a spiral copper wire, the side of the candle is provided with a spiral groove matching the heat-conducting wire, the heat-conducting wire is arranged in the spiral groove, one end of the heat-conducting wire is connected to the thermistor, the battery pack and the thermistor are arranged at the bottom of the inner cup, the light-emitting component is arranged on the outer surface of the inner cup, and the battery pack, the thermistor and the light-emitting component are connected in sequence through wires.

[0007] In some embodiments, a partition is further included, which is located inside the inner cup. The partition is arranged below the candle and above the battery pack and the thermistor. A first small hole is provided on the partition, and the heat conductive wire passes through the first small hole.

[0008] Furthermore, the candle includes a candle block and a candle wick, and the lower end of the candle wick is higher than the partition.

[0009] In some embodiments, a second small hole is provided at the bottom of the inner cup, and a wire connecting the thermistor and the light-emitting element passes through the second small hole.

[0010] In some embodiments, the light-emitting element is composed of a plurality of point light sources arranged in a pattern or text.

[0011] In some embodiments, a filler is further included, wherein the filler is disposed between the outer cup and the inner cup, and the filler comprises a light-transmitting material.

[0012] In some embodiments, a control module is further included, and the battery pack, thermistor, the control module and the light-emitting element are connected in sequence through wires.

[0013] The beneficial technical effects of the utility model are:

[0014] 1. The temperature-sensitive luminous candle cup lamp of the present invention utilizes a spiral heat-conducting wire to conduct heat to a thermistor, thereby controlling the lighting of the light-emitting element. First, the use of the spiral heat-conducting wire avoids the problem of the light-emitting element not lighting up due to uneven candle burning. Second, the heat transfer is gradual, and the resistance of the thermistor gradually decreases, achieving the effect of the candle lighting up first and the light-emitting element gradually lighting up later. Finally, the use of optical fiber or temperature sensors is avoided, reducing production costs. In addition, the copper heat-conducting wire is not easily damaged and has a long service life.

[0015] 2. A partition is set under the candle and above the battery pack and thermistor to provide heat insulation. At the same time, the lower end of the candle wick is higher than the partition to prevent the battery from being heated, which is safer.

[0016] 3. Use point light sources to arrange in patterns or text to form luminous parts. The filling can be a mixture of small objects composed of different elements and transparent materials. Appropriate patterns, texts or small objects can be selected according to Halloween or other special themes to enhance the atmosphere. The control module can control the lighting mode of the luminous parts, such as constant light, flashing or color gradient, to further enhance the aesthetics. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The present invention will be further described below in conjunction with the accompanying drawings and embodiments. Identical components are denoted by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," and "lower" used in the following description refer to directions in the accompanying drawings, and the terms "bottom," "top," "inner," and "outer" refer to directions toward or away from the geometric center of a particular component, respectively.

[0022] like Figure 1 As shown, the temperature-sensitive luminous candle cup lamp of the present invention has an outer cup 1 and an inner cup 2, with a filler 3 between the outer cup 1 and the inner cup 2, and a candle block 4 and a candle wick 5 in the inner cup 2. The filler 3 is a transparent solid, so the light-emitting part 7 on the surface of the inner cup 2 can be seen. The light-emitting part 7 is composed of a series of point light sources arranged according to a specific pattern or text. Specifically, when the light-emitting part 7 is lit, the colorful artistic word "Halloween" can be displayed. A light-emitting part power supply line 6 is connected under the light-emitting part 7.

[0023] Figure 2This is a structural schematic diagram of the temperature-sensing luminous candle cup lamp of the present invention viewed from the left side. It can be seen that the height of the outer cup 1 is higher than the height of the inner cup 2, and the height of the inner cup 2 is higher than the height of the filler 3. A heat-conducting wire 8 is spirally arranged on the inner wall of the inner cup 2. The heat-conducting wire 8 is made of copper. One end of the heat-conducting wire 8 is located at the top of the candle block 4, and the other end is located at the bottom of the candle block 4. A partition 9 is provided at the bottom of the candle block 4. The candle wick 5 is vertically arranged in the center of the candle block 4. The lower end of the candle wick 5 does not contact the partition 9. A thermistor 10, a battery pack 11 and a control module 12 are provided in the space below the partition 9. The partition 9 is provided with a small hole, allowing the heat-conducting wire 8 to be connected to the thermistor through the small hole. The battery pack 11, thermistor 10 and the control module 12 are connected in sequence through the circuit. There is also a small hole at the bottom of the inner cup 2, allowing the light-emitting component power supply line 6 connected to the control module 12 and the light-emitting component 7 to pass through the small hole.

[0024] like Figure 3 As shown, the surface of the candle block 4 is provided with a spiral groove 13, which is a groove whose shape matches the heat-conducting wire 8 and whose width and depth are slightly larger than the diameter of the heat-conducting wire 8. When installing, first insert the bottom of the heat-conducting wire 8 into the small hole of the partition 9 to obtain Figure 3 The lower structure, then align the bottom of the spiral groove 13 on the surface of the candle block 4 with the top of the heat conductor 8, rotate the heat conductor 8 into the spiral groove 13, and at the same time, the candle block 4 is downward, and continues to rotate until the bottom of the candle block 4 contacts the partition 9, and the installation is complete.

[0025] The working principle of the temperature-sensitive luminous candle cup lamp of this utility model:

[0026] When a candle wick 5 is lit with a lighter, the candle block 4 near the candle wick 5 melts into wax oil, which then contacts the heat conducting wire 8. The heat conducting wire 8 is made of copper and has excellent thermal conductivity (401 W / mK). Assuming the room temperature is 20°C, the wax oil of the low-temperature wax is 40°C, and the total length of the heat conducting wire 8 is approximately 50 cm, the maximum time required for heat conduction is only 10 seconds. When ordinary wax is used instead of low-temperature wax, the heat conduction time is further shortened. The resistance of the thermistor 10 changes due to heat. This change is a variable process. As the resistance gradually decreases, the current supplied by the battery pack 11 gradually increases. The control module 12 receives the gradually increasing current. The control module 12 can be configured to gradually illuminate the light-emitting element 7 under these conditions. In summary, the candle is first lit, and the candlelight shines through the transparent filler 3, allowing the user to appreciate the beauty of the candlelight. Then, the light-emitting element 7 gradually illuminates, giving the user a sense of interaction and the user to appreciate the beauty of the light. The combination of the candlelight and the gradually illuminated light creates a magnificent effect.

[0027] Among them, the reason why the heat conducting wire 8 is set in a spiral shape is that the burning of the candle wick 5 may be offset, resulting in a large amount of wax oil existing on only one side. If the heat conducting wire 8 is only set on one side, it may not be heated. However, if it is set in a spiral shape, that is, wax oil exists on any side, it can be heated, ensuring heat transfer and ensuring that the light-emitting part 7 can always light up.

[0028] Among them, the spiral groove 13 is provided and the width and depth of the spiral groove 13 are slightly larger than the diameter of the heat-conducting wire 8, which can ensure that the heat-conducting wire 8 is in contact with the air in the spiral groove 13 more and in contact with the candle block 4 less. Even if it is in contact with the candle block 4, the contact part will melt quickly, which can reduce the influence of the heat absorption of the candle block 4 on the heat conduction; and the combination of the spiral groove 13 and the heat-conducting wire 8 is similar to a threaded decoration, which can also have a certain decorative and aesthetic effect.

All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, certain improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
