Description

Technical Field

[0001] This application relates to the field of wax melting lamps, and in particular to a wax melting lamp that facilitates the diffusion of fragrance through controlled airflow. Background Technology

[0002] Existing aromatherapy wax devices generally employ the principle of heat-melting and fragrance release. They use electric heating or open flame to melt the wax and release aroma molecules. These devices are widely used in enclosed or semi-enclosed spaces such as hotels, bedrooms, and studies. Their working principle relies on the natural diffusion of aroma molecules. In a static air environment, fragrance substances gradually migrate into the surrounding space through Brownian motion. However, this passive diffusion method exhibits significant limitations in practical applications: when the ambient airflow rate is below 0.1 m / s, the effective horizontal sensing distance of aroma molecules is usually no more than 50 cm, resulting in a noticeable odor concentration gradient within the small space. Users need to be close to the device to obtain a good olfactory experience. If external airflow devices such as fans are used directly, the aroma molecules are rapidly diluted and migrate disorderly with the airflow due to the large airflow speed and range, causing an exponential decrease in effective aroma concentration. Ultimately, this results in insufficient overall fragrance perception in the space, failing to achieve the purpose and effect of aromatherapy.

[0003] The root cause of these technical defects lies in the failure of traditional devices to establish controllable airflow. First, natural diffusion is limited by physical constraints; the concentration distribution of aroma molecules in three-dimensional space is inversely proportional to the square of the distance. This characteristic leads to excessively high concentration peaks around the device while the concentration drops sharply at farther points. Second, existing technologies passively rely on the randomness of ambient airflow, unable to construct directional diffusion paths in stable environments or establish local concentration maintenance mechanisms under strong airflow conditions. More importantly, traditional devices lack dynamic adjustment capabilities, failing to adjust the aroma release intensity and diffusion direction in real time according to changes in environmental parameters. Summary of the Invention

[0004] The purpose of this application is to overcome at least one deficiency of the prior art and to provide a wax lamp that facilitates the controlled airflow diffusion of fragrance, the aroma lamp having an airflow diffusion component to achieve a larger area and fragrance release.

[0005] To achieve the above objectives, this application discloses a wax melting lamp that facilitates the controlled diffusion of fragrance via airflow. The wax melting lamp includes a base for placing aromatherapy substances, a heat source component, and an airflow diffusion component. The heat source component contains at least one heat-generating light source, and the radiative heat transfer path of the light source covers the aromatherapy substance area, causing the aromatherapy substance to undergo a phase change or volatilize. The airflow diffusion component is located below the aromatherapy substance and generates a directional airflow, thereby enhancing the spatial diffusion efficiency of the aromatherapy substance's volatilized products.

[0006] In some embodiments, the aromatherapy substance includes a container and a wax located within the container, the container having at least one opening facing towards the ambient space; the container is a light-transmitting glass or quartz container. Preferably, the opening size of the container is adjustable to accommodate different evaporation rate requirements. Preferably, the opening of the container faces towards a heat source component.

[0007] In some embodiments, the aromatherapy substance and the base are detachably connected via a snap-fit, threaded, or magnetic interface, facilitating the replacement / addition and cleaning of the aromatherapy substance.

[0008] In some embodiments, the base has multiple air outlets facing different directions. Preferably, the orientation of the air outlets is adjustable. Further, the adjustable orientation of the air outlets is achieved through a louvered airflow guide mechanism.

[0009] In some embodiments, the base has multiple air outlets that can be manually opened and closed and oriented in different directions.

[0010] In some embodiments, the base is provided with an auxiliary heating module within the mating surface with the aromatherapy substance, and the auxiliary heating module forms a surface contact heat conduction interface with the bottom of the aromatherapy substance; preferably, the auxiliary heating module is one or a combination of a heating element or a heating wire. The operating power of the auxiliary heating module complements that of the heat source component, and when the phase change temperature of the aromatherapy substance within the translucent aromatherapy substance does not reach a preset threshold, auxiliary heating is automatically activated to accelerate the evaporation process of the substance.

[0011] In some embodiments, the thermal light source assembly includes a lamp holder and a light source cooperating with the lamp holder, the light source being one or a combination of incandescent bulbs and halogen lamps. Furthermore, the lamp holder is equipped with a temperature-controlled fuse protection device to ensure electrical safety under high-heat conditions.

[0012] In some embodiments, the base integrates a human body detection unit. The human body detection unit identifies the user's activity status based on microwave radar or pyroelectric sensors, and then adjusts the operating status, mode, or power accordingly.

[0013] In some embodiments, the base integrates a temperature sensor. Preferably, the temperature sensing unit collects real-time data on the temperature of the outer wall of the light-transmitting aromatherapy substance and the ambient temperature, and maintains the optimal evaporation temperature range of the aromatherapy substance by dynamically adjusting the fan speed and the power of the auxiliary heating module.

[0014] In some embodiments, the wax melting lamp further includes a control circuit for driving the heat source assembly and the airflow diffusion assembly. Preferably, the control circuit is disposed within the base. Further, the control circuit has a Bluetooth or Wi-Fi module to enable remote operation.

[0015] In some embodiments, the airflow diffusion component is one of an axial flow fan, a cross-flow fan, or a centrifugal fan.

[0016] Compared with the prior art, this application has at least one of the following beneficial technical effects:

[0017] 1. This application generates directional airflow through an airflow diffusion component, which effectively enhances the spatial diffusion efficiency of volatile products of aromatherapy substances. It breaks through the problem of odor concentration gradient in small spaces caused by traditional passive diffusion. Users can obtain a good olfactory experience without close contact with the device, and solves the limitation of the existing technology that the effective sensing distance of aroma molecules is short under low ambient air flow rate.

[0018] 2. The air outlet of this aroma lamp is adjustable or can be manually turned on and off, allowing it to flexibly adjust the diffusion direction and evaporation rate of the aroma according to different needs and environmental conditions. This overcomes the shortcomings of existing technologies that passively rely on the randomness of ambient air flow and cannot construct directional diffusion paths or form a local concentration maintenance mechanism.

[0019] 3. The base integrates a temperature sensor, a human body detection unit, and a dynamic adjustment function, which can adjust the aroma release intensity in real time according to changes in environmental parameters. The auxiliary heating module and the heat source component complement each other in terms of working power, ensuring that the aroma substances are in the optimal volatilization temperature range. This achieves intelligent dynamic adjustment of aroma release, making up for the lack of dynamic adjustment function in traditional devices.

[0020] The beneficial effects listed above are not exhaustive of all advantages. Other potential beneficial effects and detailed technical implementation methods will be further disclosed in the embodiments or other descriptive sections of this application. Attached Figure Description

[0037] See attached document Figures 1 to 10 In this embodiment, a wax melting lamp that facilitates the controlled airflow diffusion of fragrance is provided. It mainly consists of a base 1, a heat source component 3, and an airflow diffusion component 4. The components work together to achieve efficient volatilization and directional diffusion of the fragrance substances.

[0038] Specifically, the base 1 has good mechanical strength and heat resistance, which can stably support the entire aroma lamp structure and effectively resist the heat generated by the heat source component 3 when it is working.

[0039] In this embodiment, to achieve the purpose of aromatherapy, the aromatherapy substance 2 with aromatherapy wax is detachably or fixedly installed on the base 1. In terms of material, the aromatherapy substance 2 includes a container and a scented wax placed inside the container. More specifically, the container is made of light-transmitting glass, which has good light transmittance and chemical stability, allowing the light from the heat source component to pass through smoothly without affecting the volatilization process of the aromatherapy substance.

[0040] In terms of the connection structure, the container of the aromatherapy substance 2 is placed directly on the base 1. In a further embodiment, to improve the installation stability of the container, refer to the attached... Figure 9 The base 1 is provided with an interface 7 for connecting to the container. The container and the base 1 are connected separately through the interface 7, for example, by a snap-fit ​​structure. The connection structure makes operation simple and allows users to quickly disassemble and install the aromatherapy substance 2, thereby facilitating the replacement, replenishment, and addition of the aromatherapy wax, as well as the cleaning of the aromatherapy substance 2.

[0041] It should be understood that in the snap-fit ​​interface design between the aromatherapy substance 2 and the base 1, the shape and size of the snap-fit ​​can be adapted and adjusted according to actual needs. Its design principle and manufacturing process are conventional technologies in the field of plastic product molding and mechanical connection. Those skilled in the art can easily implement it based on known technologies. It is only briefly mentioned here to illustrate its feasibility, without going into further detail.

[0042] Regarding the aromatherapy substance 2, the container of the aromatherapy substance 2 has at least one opening 201, and the opening 201 faces the ambient space. The size of the opening 201 is adjustable. In the specific implementation of the adjustment structure of the opening 201, an adjustable flow guide structure is set at the opening 201 of the container, such as using multiple movable baffles. The position of the baffles is adjusted by rotating or sliding to change the effective flow guide area of ​​the opening 201, thereby adapting to different evaporation rate requirements.

[0043] In a further description, in this example, the opening 201 of the container faces directly upwards, allowing the aroma molecules generated by the evaporation of the scented wax to diffuse smoothly into the ambient space.

[0044] In this embodiment, the heat source component 3 is installed in the base 1. The heat source component 3 includes a lamp holder 302 and a light source 301 that cooperates with the lamp holder 302. The light source 301 is selected from incandescent bulbs or halogen lamps. Specifically, incandescent bulbs have good spectral characteristics and heating effect, while halogen lamps can provide higher color temperature and more concentrated light intensity. Both can not only meet the heating requirements of aromatherapy substances, but also adjust the lighting atmosphere of the volatilization environment to a certain extent.

[0045] It should be understood that the electrical connection of this aroma lamp adopts a parallel connection method known to those skilled in the art to ensure that each component can operate independently and stably without interfering with each other. For specific circuit wiring details, please refer to the circuit design of conventional lamps and small household appliances. This part is within the scope of existing technology and will not be elaborated here.

[0046] More specifically, the lamp holder 302 is made of high-temperature resistant material and has an internal temperature protection device. When the temperature of the lamp holder 302 is too high, the protection device can quickly cut off the circuit to ensure electrical safety under high-temperature conditions and effectively prevent safety accidents caused by overheating.

[0047] As one of the core structures of this embodiment, the airflow diffusion component 4 is also installed inside the base 1. The base 1 is provided with at least one air outlet 401 that cooperates with the airflow diffusion component 4. In this example, the base 1 has multiple air outlets 401 facing different directions, such as facing the top, front, and rear of the aromatherapy substance 2, respectively. Refer to the attached drawing. Figure 9The orientation of the air outlet 401 can be designed to be adjustable through a louvered airflow guiding mechanism. This mechanism consists of multiple louvered blades 403 that can rotate in tandem. Users can manually adjust the angle of the louvered blades 403 to change the orientation of the air outlet, thereby controlling the direction and range of aroma diffusion. The airflow diffusion component uses an axial flow fan 402, which generates a directional airflow that blows out from the air outlet 401. This airflow combines with the aroma molecules produced by the phase change or volatilization of the fragrance substances caused by the heat source component 3, enhancing the spatial diffusion efficiency of the fragrance substance's volatilization products. The directional airflow transports aroma molecules along a set direction and path to a greater distance, avoiding the problem of excessively high concentrations of aroma molecules at close range and insufficient concentrations at distant ranges, which is common in traditional natural diffusion methods. This allows the aroma to be evenly distributed within a larger space, improving the user's olfactory experience.

[0048] In addition, in the appendix Figure 4 , 5 As can be seen in Figure 8, the base 1 is equipped with a control circuit 5 that drives the thermal light source component 3 and the airflow diffusion component 4. The control circuit 5 may have a Bluetooth module, which can be connected to mobile devices such as mobile phones via Bluetooth to realize remote operation. Users can control the aromatherapy lamp from a certain distance via a mobile APP, adjust the brightness and power of the thermal light source component 3, and control the wind speed of the airflow diffusion component 4, thereby improving the convenience and flexibility of use.

[0049] It should be understood that the dimming control circuit 5 in this aromatherapy lamp is based on constant current drive and PWM dimming technology commonly used in the field. Its circuit topology, component selection, and parameter matching are all existing technologies well known to those skilled in the art. For example, a switching power supply can be used in conjunction with a constant current chip to achieve stable driving of the light source 301, and the power of the light source can be adjusted by using a microcontroller to output a PWM signal to control the duty cycle of the MOS transistor. These technologies have been widely used in the lighting field, and this application has not elaborated on them here because the implementation of these circuits does not require creative effort from those skilled in the art, and mature products or solutions can be selected and adapted according to actual needs.

[0050] Meanwhile, the communication protocol between the Bluetooth module in control circuit 5 and the mobile APP, as well as the specific design and development of the APP, belong to mature technologies in the fields of communication and software. They can be implemented using existing common solutions on the market. The details are not disclosed here because these are known and existing technologies that can be implemented by those skilled in the art without creative effort.

[0051] In a further design of this embodiment, refer to the appendix. Figure 10An auxiliary heating module 8 can also be set in the mating surface of the base 1 with the aromatherapy substance 2. The auxiliary heating module 8 is a heating element, which is a semiconductor heating element with good thermal conductivity and stability. The heating element and the bottom of the aromatherapy substance 2 form a surface contact heat conduction interface, which can evenly transfer heat to the aromatherapy substance in the aromatherapy substance 2.

[0052] The auxiliary heating module 8's operating power complements that of the heat source component 3. When the temperature sensor integrated on the base 1 detects that the phase change temperature of the aromatherapy substance 2 has not reached the preset threshold, the auxiliary heating module 8 automatically starts, accelerating the evaporation process of the aromatherapy substance. The temperature sensor collects real-time data on the outer wall temperature of the aromatherapy substance 2 and the ambient temperature, and transmits the data to the control circuit within the base 1. The control circuit 1 dynamically adjusts the speed of the axial flow fan 402 and the power of the auxiliary heating module to maintain the aromatherapy substance within the optimal evaporation temperature range, ensuring the stability and uniformity of aroma release.

[0053] In a further design of this embodiment, in the appendix Figure 2 and attached Figure 6 As can be seen, the base 1 of the aroma diffuser lamp also integrates a human body detection unit 6, which is connected to the control circuit 5. In practical applications, the human body detection unit 6 integrated in the base 1 of this aroma diffuser lamp plays an important role. For example, in a bedroom setting, the human body detection unit 6 identifies the user's activity status based on microwave radar or pyroelectric sensors. When a user enters the bedroom and walks to the bedside, the human body detection unit 6 senses the human activity, the aroma diffuser lamp automatically turns on, and starts operating according to the preset mode. The heat source component 3 and the airflow diffusion component 4 work together to evenly diffuse the fragrance throughout the entire bedroom space. If the user gets up and moves around at night, the human body detection unit 6 senses the change in activity and automatically adjusts the working status of the aroma diffuser lamp, such as appropriately reducing the power of the heat source component 3 to reduce the intensity of fragrance release, while adjusting the wind speed and air outlet direction of the airflow diffusion component 4 to concentrate the fragrance diffusion range more near the user's activity area, avoiding the fragrance being too strong and affecting the user's activity experience. At the same time, it can also save energy, extend the use time of the aromatherapy substance, and improve the intelligence and practicality of the product.

[0054] It should be noted that the specific hardware structure and working principle of the human body detection unit 6 are mature technologies in this field. For example, microwave radar sensors detect human activity by emitting and receiving microwave signals, while pyroelectric sensors use infrared rays emitted by the human body to sense the presence of the human body. These technical principles and implementation methods are all within the scope of existing technologies. Those skilled in the art can select appropriate sensor models and install and debug them according to actual needs. The implementation details will not be elaborated here.

[0055] In practical applications, such as in a bedroom setting, users can first place the aromatherapy substance 2 into the aromatherapy substance 2, and then install the aromatherapy substance 2 onto the base 1. After turning on the aromatherapy lamp, the heat source component 3 starts working, and the emitted heat covers the main area of ​​the aromatherapy substance 2 through the radiative heat transfer path, causing the aromatherapy substance in the aromatherapy substance 2 to undergo a phase change or volatilize due to heat. At the same time, the airflow diffusion component 3 starts, and the axial flow fan 402 generates directional airflow, blowing out from multiple air outlets 401 facing different directions, carrying the volatilized fragrance molecules to all corners of the bedroom. When users need to adjust the fragrance concentration or diffusion range, they can manually adjust the louvered guide mechanism at the air outlet 401 to change the direction and range of the airflow, or remotely adjust the power of the heat source component 3 and the wind speed of the airflow diffusion component 4 via a mobile APP. If used at night, the brightness of the light source 301 can also be adjusted to create a warm and comfortable atmosphere. Compared to traditional scented candles, this aroma lamp significantly extends the effective sensing distance of fragrance molecules in environments with low airflow rates. This avoids the problem of obvious odor concentration gradients in small spaces that traditional devices can solve. Users can enjoy a uniform fragrance experience without having to get close to the lamp, greatly improving the product's practicality and user experience.

[0056] In another implementation scenario, such as in a study, where environmental conditions are typically relatively stable, users can choose different aromatherapy substances to add to aromatherapy substance 2 according to their reading or work habits, and control the evaporation rate by adjusting the size of the opening 201 of aromatherapy substance 2. For example, when engaged in deep reading, an aromatherapy substance with a refreshing and invigorating scent can be selected, and the opening size of aromatherapy substance 2 can be appropriately reduced to allow the fragrance to be released slowly. Combined with the directional airflow generated by the axial fan 302, the fragrance is evenly diffused to every corner of the study, creating a comfortable and pleasant working atmosphere. When it is necessary to temporarily leave the study, the aromatherapy lamp can be remotely turned off via a mobile app, or adjusted to a low-power operating mode, saving energy while maintaining the longevity of the indoor fragrance. Compared with traditional aromatherapy devices, the application of this aromatherapy lamp in a study environment can more precisely control the release and diffusion of fragrance, meeting personalized needs in different scenarios and fully demonstrating its advantages and value in practical applications.

[0057] The above embodiments describe in detail the structural composition of this aromatherapy lamp, the connection and cooperation relationships of its components, its working principle, and its operation method. Through specific application scenarios, they demonstrate its significant advantages and beneficial effects compared to traditional aromatherapy devices, providing clear and explicit technical guidance for those skilled in the art to successfully realize this invention. Of course, those skilled in the art can make appropriate adjustments and optimizations to the materials, structural parameters, etc., in the above embodiments according to specific needs in practical applications, but these adjustments all fall within the protection scope of this utility model.
