Background technique

Aromatherapy has attracted the attention of most members of the scientific community, and aromatherapy practitioners have long believed that smells and fragrances can be used to reduce stress and promote relaxation. Scientists have also confirmed through experimental research that aroma can affect emotions and behaviors. There are two mechanisms of aromatherapy: one of which is that fragrance affects the brain through the olfactory system, especially the limbic nervous system. Another mechanism is the pharmacological action of essential oils. Studies have found that aromatherapy can quickly affect mood and behavior, and the study also found that candle dimming can also promote relaxation and a happy mood.

In addition, the soft candlelight of candles is also known to induce joy and relaxation. In the hearts of young people, candles have aesthetic value. Its soft and warm candlelight can create a romantic atmosphere in the environment. For cultural, traditional or religious reasons, candlelight can also bring a special sense of calm and wellness that other commercial lights cannot.

In the past, liquid fragrances were usually placed on a ceramic dish, and a lit candle was placed under the ceramic dish. The heat of the candle flame caused the fragrance to evaporate into the air. This method is widely used in households and commercial places. However, the candle flame can be as high as 1200 degrees Celsius, and it is easy to cause a fire accident if you do not pay attention to it when using it.

Afterwards, scented candle lights appeared, that is, aromatics were mixed in the wax of the candle, and when the candle was lit, it would emit an aromatic smell. It integrated candlelight and fragrance, and it was very popular among young people. There is a fire accident.

As the use of fragrances for the purpose of maintaining health is more and more accepted by people, in recent years, electric heating fragrance equipment has appeared. The fragrance is mixed in the liquid. When the solution is heated, the water vapor carries the fragrance and emits it into the air. . However, this kind of equipment is powered by AC mains, the solution is easy to conduct electricity, and there is a potential electrical fire hazard in long-term use.

On the other hand, candles remain popular due to the warmth and softness of their light, which cannot be replaced by other commercial artificial lights. In order to meet the demand, many candle simulation electronic products have been produced and launched, but most of the simulation effects are not good, especially the softness and fragrance of candlelight cannot be safely imitated at the same time.

The reason why existing LED candle lamps cannot replace candles is as follows: the simulated flames of many candle lamps are constantly swaying and flickering. The constant flickering of the simulated flame can create tension rather than the peace of mind that an actual candle can provide. In addition, real candles only sway when there is wind, and existing candles cannot sway randomly. Furthermore, the light intensity of the luminous regions of the simulated flames of the existing simulated candle lamps is consistent, but the actual candle flames have different brightness and colors in different regions due to different temperatures in different regions, for example, Temperatures can reach as high as 600 degrees Celsius in the dark blue region and more than 1,200 degrees Celsius in the bright yellow region.

The beneficial effects of the present invention are as follows:

1. The wick of the present invention can shake occasionally like a real flame. The driving mechanism of the present invention intermittently generates force on the pendulum, thereby causing the wick to swing intermittently. When the wick swings, the light intensity distribution on the reflective curved surface will also change correspondingly, so that the wick will produce an actual candle flame. The general shaking effect, and because the driving mechanism generates force intermittently, it can avoid the tension caused by the wick of the simulated candle lamp in the prior art swinging all the time. The shaking effect of this scheme is closer to the actual candle flame, so that it can Bring joy and relaxation to people.

The present invention achieves high simulation effect through mechanical and electronic improvements, and at least one light source emits light in a cyclic working mode through the reflection of the wick to form a high simulation effect of shaking and flickering.

2. Compared with direct light, the reflected light can have the characteristics of soft and weak candlelight.

3. The light source of the present invention produces a soft and flickering light effect under the control of the program, which can highly simulate the brightness and flickering effect of different regions caused by the release of hydrocarbons when the actual candle flame is burning. The light source of the present invention works cyclically in the high-light mode and the dark-light mode at a set frequency, so that the light intensity emitted by the light source changes at a preset frequency, so that the wick produces a flame like the actual candle flame due to the burning of the candle. flickering effect.

4. In order to highly simulate the actual candle flame, the present invention gathers the reflected indirect light in the middle of the wick, and gradually fades to the periphery, so as to imitate the different brightness of different regions of the actual candle flame. The light intensity of the slope groove of the wick is greater than the light intensity of the outer edge of the left reflective slope and the right reflective slope, so that the wick presents the effect of an actual candle flame, that is, the center of the flame is brighter than the periphery of the flame.

5. The reflective curved surface of the wick and the curved surface of the backlight each form a streamlined airflow track. When the aromatic airflow passes through the assembly hole of the wick, it rises along the streamlined airflow track of the wick, and then forms an airflow around the top of the wick. The vortex, the vortex of the airflow causes the wick to shake naturally, which in turn changes the light intensity distribution on the reflective surface, so that the wick produces a realistic effect of flickering candlelight. The bursts of fragrance and the natural flickering candlelight make people feel happy and comfortable to relax.

In addition, when the simulated candle lamp is moved or the wick is blown by outside wind, the streamlined airflow track of the wick can also form an airflow vortex above it, which in turn changes the light intensity distribution on the reflective surface and produces a realistic effect of flickering candlelight.

6. The present invention involves a variety of driving mechanism designs. The circuit board can be detachably installed in the casing, which is convenient for replacing the circuit board for different driving mechanisms. The manufacturer can match and assemble different driving mechanisms with other components of the simulation candle lamp, which is convenient It is fast and reduces production costs.

When the fan is started, the outside airflow enters the ventilation chamber through the ventilation groove of the base, and then enters the cylindrical cavity through the ventilation hole and the ventilation opening, and forms an aromatic airflow when passing through the fragrance agent, and the aromatic airflow passes through the ventilation hole. The air hole enters the cavity of the fixed shell, and finally emits to the outside world through the through hole of the wick assembly, which is not only safe, but also has a good fragrance effect. The speed of the fan can be adjusted according to the user's preference, or according to the space that the aroma smell needs to fill.

8. Not only can it be powered by AC mains, but it can also be directly powered by a variety of lithium batteries.

9. Built-in wireless transceiver module for easy control.

10. In order to prevent the smell of aromatics from mixing with the smell of melted paraffin to affect the curative effect, the present invention separates the essential oil from the wax. The essential oil can be stored in a replaceable sachet, and the fragrance can be taken out of the device by the above-mentioned airflow. Users can control the concentration of fragrance by adjusting the fan speed.

11. The soft and faint light and the aromatherapy effect work together to achieve relaxation and calm mood.

The wick 30 includes a reflective part 31, a pivot part 32 and a pendulum 33 integrally formed. The pivot part 32 is located between the reflective part 31 and the pendulum 33. The wick 30 is pivotally mounted on the shell through the pivot part 32. Generally, the reflective portion 31 extends out of the casing, and the pendulum 33 is located in the casing.

The reflective curved surface 312 is composed of a left reflective slope surface and a right reflective slope surface, and the left reflective slope surface and the right reflective slope surface A slope groove that gradually decreases from bottom to top is formed between them. Correspondingly, a protrusion matching the slope groove is formed in the middle of the backlight curved surface 313. The vertical line is bent, such as 15 degrees, and the lower end of the reflective portion 31 is bent toward the reflective curved surface 312 , so that a streamlined airflow track is formed on the reflective curved surface 312 and the backlight curved surface 313 .

The outer surface of the pendulum 33 is surrounded by a bottom surface, a circumferential side surface and a cone surface from bottom to top, and the bottom surface can be a hemispherical surface or a plane.

The light emitted by the light source 40 is condensed and then incident obliquely on the reflective curved surface 312 of the wick 30, and part of the light emitted on the left reflective slope and the right reflective slope is reflected into the groove of the slope, and then reflected by the groove of the slope. Entering the human eye, another part of the light that hits the left reflective slope and the right reflective slope is directly reflected into the human eye. In this way, the light intensity of the groove of the slope is greater than the light intensity of the outer edge of the left reflective slope and the right reflective slope , so that the wick 30 presents the effect of an actual candle flame, that is, the center of the flame is brighter than the periphery of the flame. Preferably, the light source 40 is located directly under and in front of the reflective curved surface 312 .
