[0002] Aromatherapy candles have the characteristics of fresh and pleasant fragrance. They are a kind of craft candles with rich and varied shapes and beautiful colors. The natural plant essential oils contained in them emit pleasant fragrance when burned, which has the effects of beauty care, soothing nerves, purifying air and eliminating odors.

[0003] With people's demand for a better life, solid wax bodies with aromatherapy functions and various heating methods for scented candles are emerging in an endless stream. At present, wax melting aromatherapy products mostly use GU10 light sources to generate heat sources to melt the wax body, candles with cloth cores (or wood cores) to ignite and self-ignite, and candle baking containers to melt the wax body to produce fragrance diffusion effects. There are high energy consumption, high temperature of the product itself, smoke and soot, potential risk of harm to the environment and people, and limited protection measures. Open flames and the smoke and dust they produce are potentially dangerous, so many people choose to use light as a heat source, which affects the surrounding environment, and the high temperature of the product itself can potentially cause harm to people.

[0004] Chinese patent CN219983521U discloses an LED scented candle, which can emit various lighting effects when the scented candle is lit through the structural design of the light generating mechanism, thereby improving the overall user experience of the scented candle. However, the scented candle is still lit with an open flame, which still poses a potential risk of harm to the environment and people.

[0031] See also Figure 1The low-voltage retractable heating device shown in an embodiment of the utility model is used to heat and diffuse aromatherapy candles, and has both lighting and aromatherapy functions. It does not cause any potential harm to the environment and people when in use, and is safe, energy-saving and environmentally friendly. The heating device includes: a base 1, a candle bottle 2, a light-emitting structure 4, a retractable heating module 3, a transformer, a controller, and a gravity sensor.

[0032] A candle bottle 2 for holding scented candles is arranged on a base 1, wherein scented wax is contained in the candle bottle 2, a light-emitting structure 4 is arranged next to the candle bottle 2, and a retractable heating module 3 is arranged above the candle bottle 2. The retractable heating module 3 includes a heating rod 31 and a retractable structure for driving the heating rod 31 to extend into the candle bottle 2 or to retract. The heating rod 31 extends into the center of the wax body to generate heat and melt the wax body, and continuously heats the wax body to produce a fragrance diffusion effect. The light-emitting structure 4 composed of two groups of light-emitting lampshades continuously emits light, and has both atmosphere lighting and aromatherapy functions.

[0033] Specifically, the transformer is electrically connected to the retractable heating module 3, the controller is electrically connected to the retractable heating module 3 and the transformer respectively, the heating rod 31 has a first heating state and a second heating state, and the temperature of the heating rod 31 in the first heating state is higher than the melting point of the aromatherapy wax. The telescopic structure includes a motor housing 32 connected to the light-emitting lampshade through a connecting arm 6, a linear motor disposed in the motor housing 32, and a slider 33 that slides along the motor housing 32 under the drive of the linear motor, and the slider 33 is fixedly connected to one end of the heating rod 31.

[0034] When the heating device is started, the controller sends a corresponding electrical signal, the linear motor starts to run, driving the slider 33 to slide downward, driving the heating rod 31 to move downward and extend into the candle bottle 2; the heating rod 31 is in the first heating state, gradually melting the wax body and continuing to move downward until it extends into the center of the wax body, and the motor stops running; the heating rod is transformed into the second heating state, and continues to heat the wax body according to the set working time to produce a fragrance diffusion effect. After the set time is reached, the controller automatically cuts off the power supply of the heating rod, and sends a corresponding electrical signal to control the linear motor to reverse, and the retractable heating module 3 retracts to the starting state.

[0035] A gravity sensor is provided on the base 1, and the candle bottle 2 is provided on the gravity sensor, and the gravity sensor is electrically connected to the controller. The gravity sensor is used to detect whether there is a scented wax body in the candle bottle 2. When the gravity sensor detects that there is no scented wax body in the candle bottle 2, the controller automatically cuts off the power supply of the heating rod and controls the retractable heating module 3 to retract to the initial state, so as to prevent the heating rod 31 from continuing to heat without the scented wax body.

[0036] The base 1 is also provided with a battery, which is electrically connected to the retractable heating module 3 and the controller. When the heating device is powered off due to a power outage or other reasons, the retractable heating module 33 can be temporarily powered by the battery to ensure that the retractable heating module 3 can be retracted to the initial state, thereby avoiding the situation in which the heating rod 31 cannot be retracted due to the solidification of the wax liquid after cooling.

[0037] The light-emitting structure 4 is composed of two groups of light-emitting lampshades. The two groups of light-emitting lampshades have different powers. By emitting light through a single light-emitting lampshade or two groups of light-emitting lampshades emitting light together, three light-emitting modes with different brightness can be realized.

[0038] Furthermore, a heat-insulating protective cover 5 is provided on the outer periphery of the candle bottle 2 to prevent the user from accidentally touching the candle bottle 2 and being burned, thereby further improving safety.

[0039] In summary, the utility model adopts an independent low-voltage powered heating rod, which automatically adjusts the height and temperature through a telescopic structure and a controller. It adopts a point heating method, directly extends into the center of the wax body to heat and melt the wax body to achieve a fragrance diffusion effect. The product itself and the wax body itself have good heat dissipation effects, and the aromatherapy effect is excellent. It is smokeless and has no potential harm to the environment and people. The comprehensive protection measures are perfect, safe, energy-saving and environmentally friendly. It adopts a luminous structure including two groups of luminous lampshades, which has both atmosphere lighting and aromatherapy functions. After stopping heating and diffusion, the heating rod shrinks quickly, and the wax liquid loss is extremely low. The heating device can be recycled by adding aromatherapy wax liquid into the candle bottle.
