Abstract
Description
Technical Field
[0001] This utility model relates to the field of aromatherapy technology, and in particular to aromatherapy devices. Background Technology
[0002] As people's living standards improve, aromatherapy has gradually become an important product for enhancing living environment and experience. Smoke diffusers produce smoke by atomizing essential oils, effectively improving indoor air quality and creating a soothing, relaxing atmosphere. They are widely used in homes, offices, hotels, and other settings. In common smoke diffusers, a touch panel or power switch is usually located on the top cover, while the mist outlet is located on the side wall. The smoke produced by the diffuser flows upwards through the outlet and easily condenses on the upper surface of the top cover, forming water droplets. This condensation can affect the user's ability to operate the touch panel and may cause slippage or accidental operation when pressing the cover, thus reducing the user experience.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Traditional aromatherapy devices have their mist outlets located on the circumferential sidewalls. The smoke flowing out of the outlets rises due to airflow. As the smoke rises, it encounters the obstruction of the top cover, creating a Karman vortex behind the top cover. This causes the smoke to condense into droplets upon contact with the upper surface of the top cover, resulting in liquid accumulation.
[0025] See Figure 1 , Figure 2 and Figure 3This utility model provides an aromatherapy device, including a housing assembly 10, an atomizing assembly 20, and a fan assembly 30. The housing assembly 10 has a receiving cavity 110 for installing other functional components. The housing assembly 10 includes a top cover 120 and a circumferential sidewall 130 located below the top cover 120. A mist outlet 140 is provided on the circumferential sidewall 130, communicating with the outside and used to discharge atomized aromatherapy smoke outside the aromatherapy device. The atomizing assembly 20 is disposed within the receiving cavity 110, and the mist outlet 140 communicates with the outlet of the atomizing assembly 20. The fan assembly 30 is disposed within the receiving cavity 110, and the air outlet of the fan assembly 30 communicates with the inlet of the atomizing assembly 20 to blow the smoke generated by the atomizing assembly 20 out from the outlet; wherein the mist outlet 140 is oriented downwards. It should be noted that "the mist outlet 140 is oriented downwards" refers to the top and bottom of the aromatherapy device in terms of its height; for example... Figure 2 In the middle, the top cover 120 is located above the circumferential side wall 130, or, in the height direction of the aromatherapy device, the direction from the bottom of the aromatherapy device along the direction close to the top cover 120 is upward, and the direction from the top cover 120 along the direction close to the bottom of the aromatherapy device is downward. Therefore, the mist outlet 140 is arranged facing downward, which means that the mist outlet 140 faces the bottom of the aromatherapy device.
[0026] During the operation of the aromatherapy device, the atomizing component 20 converts the aromatherapy liquid into aromatherapy smoke. The fan component 30 is activated to generate a stable airflow. This airflow enters through the inlet of the atomizing component 20 and carries the smoke towards the mist outlet 140. The opening of the mist outlet 140 is oriented away from the top cover 120. This causes the smoke to move away from the top cover 120 after flowing out of the mist outlet 140. Subsequently, near the mist outlet 140, the airflow results in lower pressure, creating a pressure difference with atmospheric pressure. The atmospheric pressure then pushes the smoke upward naturally.
[0027] Due to the special orientation design of the mist outlet 140, the smoke does not move directly upwards after exiting. Instead, it first moves away from the top cover 120, and then gradually rises naturally under the continuous action of airflow and pressure. This zigzag motion path, moving away from the top cover 120 before rising, effectively reduces the smoke velocity. According to fluid mechanics principles, reducing the smoke velocity can significantly reduce the formation of Karman vortices. Karman vortices are a common fluid eddy phenomenon that causes liquid to accumulate on the upper surface of the top cover 120. By optimizing the smoke flow path, this aromatherapy device can reduce the smoke velocity, effectively reduce the formation of Karman vortices, and thus reduce the contact between the smoke and the upper surface of the top cover 120, reducing the formation of liquid.
[0028] The aromatherapy essential oil is atomized into essential oil smoke through the atomizing component 20. The atomizing component 20 uses specific atomization technology (such as ultrasonic atomization, heating atomization, etc.) to transform the aromatherapy liquid into fine smoke particles, avoiding the safety hazards of traditional aromatherapy that requires ignition with an open flame. This makes the aromatherapy device suitable for more application scenarios. Moreover, users can control the generation or deactivation of the mist by controlling the atomizing component 20 to achieve precise control of the mist volume. When not in use, the atomizing component 20 can be turned off to avoid wasting essential oil and extend the lifespan of the device.
[0029] Among them, the mist formed by the atomization of aromatherapy essential oils consists of tiny droplets with poor fluidity. By setting up the fan assembly 30, the airflow generated by the fan assembly 30 when it is working blows the smoke generated by the atomization assembly 20 out of the outlet of the atomization assembly 20 and further flows to the mist outlet 140 for final discharge, preventing the smoke from accumulating at the mist outlet 140.
[0030] The top cover 120 features a visual design, allowing users to intuitively observe the internal working status of the device while also enhancing its decorative appeal. For example, the top cover 120 can be made of crystal or transparent material, improving the overall aesthetics of the device.
[0031] See Figure 2 and Figure 3 In some embodiments, the circumferential sidewall 130 includes a guide member 131 and an outer sidewall 132. The guide member 131 is disposed between the outer sidewall 132 and the top cover 120, and the mist outlet 140 is at least partially enclosed by the guide member 131. The guide member 131 guides the smoke as it flows out of the mist outlet 140, causing it to move away from the top cover 120 initially, and then rise naturally under the continuous action of the airflow, forming a tortuous motion path. This effectively reduces the smoke velocity, thereby reducing the generation of the Karman vortex phenomenon and reducing the accumulation of liquid on the upper surface of the top cover 120. The mist outlet 140 is at least partially enclosed by the guide member 131. For example, the mist outlet 140 is enclosed by the guide member 131 and the outer sidewall 132. In another embodiment, the mist outlet 140 can be formed by the guide member 131 alone, similar to a tubular component, and directly connected to the housing assembly 10. Since the smoke from the mist outlet 140 flows upwards and then downwards, meaning it bends and then flows upwards, the guide 131 is positioned between the outer wall 132 and the top cover 120. It can be understood that the guide 131 is positioned close to the top cover 120, near the top of the aromatherapy device, to prevent the downward-flowing smoke from contacting the hollow dashboard or the surface of the object on which the aromatherapy device is placed, thus preventing any impact.
[0032] See Figure 2 , Figure 3 and Figure 4 In some embodiments, the flow guide 131 has an extension 1311 extending in a direction away from the top cover 120; the extension 1311 and the outer wall 132 form a mist outlet 140, and the extension 1311 is located on the outer surface of the outer wall 132. The extension 1311 is located on the outer surface of the outer wall 132, and the mist outlet 140 extends downward along the surface of the outer wall 132, making the flow guide 131 easy to install and the mist outlet 140 more conveniently positioned downwards from the top cover 120. The extension 1311 further guides the flow of smoke, and as the smoke flows out of the mist outlet 140, the flow path of the smoke is optimized by the guidance of the extension 1311.
[0033] See Figure 2 , Figure 3 and Figure 4 In some embodiments, in the height direction of the aromatherapy device, the distance from the bottom surface of the extension 1311 to the top cover 120 is greater than the distance from the top surface of the outer wall 132 to the top cover 120. This ensures that all smoke is guided by the extension 1311 when flowing out of the mist outlet 140, preventing some smoke from escaping vertically upward from the mist outlet 140 without passing through the guide member 131.
[0034] See Figure 2 , Figure 3 and Figure 4 In some embodiments, the distance from the bottom surface of the extension 1311 to the top surface of the outer wall 132 in the height direction of the aromatherapy device is 2mm-7mm. This ensures that when the smoke flows out of the mist outlet 140, it is first guided to move away from the top cover 120 and then rises naturally. If the distance is less than 2mm, some airflow may escape vertically upward from the mist outlet 140 without being guided by the extension 1311, that is, it rises directly without bending. The flow rate of the smoke does not change, and the vortex phenomenon will still occur, resulting in liquid accumulation. If the distance exceeds 7mm, it will affect the aesthetic appearance of the device, and the airflow may not have enough time to rise before hitting the surface of the object on which the aromatherapy device is placed, causing uneven smoke diffusion.
[0035] See Figure 2 , Figure 3 and Figure 4In some embodiments, the flow guide 131 further includes a connecting portion 1312, with both ends of the connecting portion 1312 connected to the extension portion 1311 and the top cover 120, respectively. The extension portion 1311 and the connecting portion 1312 are connected to form a groove 1313. Specifically, one end of the outer wall 132 extends into the groove 1313 and is spaced apart from the groove 1313. The extension portion 1311 is located on the outer surface of the outer wall 132, and the connecting portion 1312 is located on the inner surface of the outer wall 132. The extension portion 1311 and the connecting portion 1312 form the groove 1313, ensuring that the smoke presents a "low-high-low" flow path between the flow guide 131 and the outer wall 132, such as an inverted "U" shaped flow path. The bend in the flow path effectively reduces the flow velocity of the smoke, which also reduces the Karman vortex phenomenon, further ensuring the anti-liquidation effect of this aromatherapy device. The "low-high-low" flow path makes the cross-sectional shape of the guide 131 resemble a cone, which can effectively prevent smoke from accumulating inside and on the outside of the guide 131, thus ensuring the smooth flow of smoke.
[0036] See Figure 4 In some embodiments, the inner sidewall of the groove 1313 is provided with a guide structure 150. The guide structure 150 includes a first guide surface 151. The first guide surface 151 is disposed close to the interior of the outer sidewall 132. The first guide surface 151 is inclined downward along the outer sidewall 132 toward the central axis of the aromatherapy device, so that the smoke can flow smoothly to the gap between the guide member 131 and the outer sidewall 132, ensuring that all the smoke can be guided by the guide member 131.
[0037] Furthermore, the guide structure 150 includes a second guide surface 152, which is disposed internally away from the outer wall 132. The second guide surface 152 is inclined downward along the outer wall 132 toward the outside of the aromatherapy device, so that the smoke can be smoothly bent and flow out of the mist outlet 140 under the action of the guide member 131. The first guide surface 151 and the second guide surface 152 together form a "low-high-low" flow path, so that the smoke undergoes several turns before flowing out of the mist outlet 140, further reducing the smoke flow velocity and reducing the generation of the Karman vortex phenomenon.
[0038] In some embodiments, the extension 1311 is arranged parallel to the outer wall 132. If the extension 1311 is inclined relative to the outer wall 132, the smoke flowing out of the mist outlet 140 may form a large circle when it rises, causing the smoke to become scattered. Because the smoke circle is larger and the smoke is thinner, the visual effect is poor. However, if the extension 1311 is arranged parallel to the outer wall 132, the smoke guided by the guide member 131 will move closer to the top cover 120 when it rises, the smoke will be more concentrated and the smoke effect will be more clearly visible, thus improving the visual effect.
[0039] See Figure 1 In some embodiments, the mist outlet 140 is annular and is arranged around the periphery of the circumferential sidewall 130 to ensure that the smoke spreads quickly and evenly in the space. The observed smoke is also annular, and the smoke is evenly discharged upward from the periphery of the top cover 120. This avoids excessively high local concentrations or dead zones and achieves uniform distribution of smoke in the space.
[0040] Furthermore, multiple mist outlets 140 are provided, and the multiple mist outlets 140 are equidistantly arranged around the periphery of the circumferential sidewall 130. The multiple mist outlets 140 are equidistantly arranged around the periphery of the circumferential sidewall 130 of the shell to ensure that the smoke is evenly discharged from the mist outlets 140, avoid concentration in one direction, and ensure the user's experience.
[0041] See Figure 2 , Figure 3 and Figure 5 In some embodiments, a mist outlet channel 160 is provided within the receiving cavity 110. The mist outlet channel 160 includes a first portion 161 and a second portion 162 connected to each other. The first portion 161 communicates with the outlet of the atomizing component 20. One end of the second portion 162 is connected to the first portion 161, and a guide member 131 is provided at the other end of the second portion 162. The first portion 161 slopes downward from the central axis of the aromatherapy device toward the outer wall 132; and / or, the second portion 162 extends along the height direction of the aromatherapy device toward the direction close to the top cover 120. The first portion 161 slopes downward from the central axis of the aromatherapy device toward the outer wall 132, that is, it is set downward from the center to the circumference, forming a continuous guide slope. When the smoke generated from the atomizing component 20 flows out of its outlet and into the first portion 161 of the mist outlet channel 160, it is guided by the slope, and the airflow direction is forcibly adjusted to flow downward. The second part 162 communicates with the first part 161 and extends along the height of the aromatherapy device toward the top cover 120. After exiting the outlet of the atomizing component 20, the smoke flows along the first part 161, passes through the bend where the first part 161 and the second part 162 communicate, and then flows out along the second part 162.
[0042] The inclined design allows the liquid formed after the smoke is liquefied to flow down the surface of the first separator 171 and accumulate at the bend between the first part 161 and the second part 162. This bend is exposed to the outside, which allows the liquefied liquid to evaporate more quickly, thereby reducing the accumulation of liquid in the mist outlet channel 160 and avoiding mold or odor problems caused by long-term accumulation. It also reduces the frequency of manual cleaning by the user.
[0043] See Figure 2 and Figure 3In some embodiments, the housing assembly 10 further includes a first partition 171 and a second partition 172. The first partition 171 is located in the receiving cavity 110 corresponding to the circumferential sidewall 130 and divides the receiving cavity 110 into a first sub-receiving cavity and a second sub-receiving cavity. The second partition 172 is located in the first sub-receiving cavity and is spaced apart from the first partition 171 to form the aforementioned mist outlet channel 160. The atomizing component 20 is located in the second sub-receiving cavity to avoid interference from other components during the atomization process of the atomizing component 20. The outlet of the atomizing component 20 is connected to the mist outlet channel 160 through the air guide pipe 210, forcing the atomized smoke to flow through the preset channel. The mist outlet channel 160 is formed by the first separator 171 and the second separator 172, and is connected to the mist outlet 140. The atomizing component 20 ensures that the smoke generated after atomization by the atomizing component 20 can flow smoothly through the air guide duct 210 to the mist outlet channel 160 and then to the mist outlet 140, and finally diffuse into the environment, thereby reducing the loss of essential oil smoke during the transmission process and further improving the diffusion efficiency.
[0044] Furthermore, the housing assembly 10 also includes a light-emitting component 180, and a receiving cavity is formed between the second partition 172 and the top cover 120, within which the light-emitting component 180 is located. The second partition 172 may, for example, separate the atomizing component 20 from the light-emitting component 180, with the light-emitting component 180 located within the second partition 172, preventing the smoke generated by the atomizing component 20 from contacting the electronic components within the light-emitting component 180, corroding the components, or causing a short circuit. For example, if the smoke liquefies and becomes liquid, it may adhere to the electronic components of the light-emitting component 180, and the aromatherapy liquid may be corrosive.
[0045] The light-emitting component 180 includes, for example, an LED bead and a circuit board. The LED bead is located on the circuit board and is electrically connected to the circuit board. The LED bead is arranged, for example, corresponding to the top cover 120. By arranging the LED bead, the light emitted by the LED bead illuminates the smoke at the mist outlet 140, thereby enhancing the visual effect of the aromatherapy device and further improving the user experience.
[0046] In some specific embodiments, see Figure 2 and Figure 3The fan assembly 30 includes a fan 310 and an air guide shroud 320. One end of the air guide shroud 320 is located near the air outlet of the fan 310, and the other end is located near the atomizing assembly 20. The inner diameter of the air guide shroud 320 gradually narrows from the end near the fan 310 towards the atomizing assembly 20. The air guide shroud 320 is used to guide the air generated by the movement of the fan 310 to the atomizing assembly 20. The end of the air guide shroud 320 near the fan 310 is, for example, a guide air inlet. When the fan 310 is working, it generates airflow, which is blown into the air guide shroud 320 through the guide air inlet. The airflow entering the air guide shroud 320 is blown towards the atomizing assembly 20, causing the smoke generated by the atomizing assembly 20 to be compressed and flow from the outlet of the atomizing assembly 20 to the mist outlet channel 160, and finally out from the mist outlet 140. The air guide shroud 320 can be, for example, a conical structure, similar to a trumpet shape. The inner wall of the air guide shroud 320 is arc-shaped, forming an arc-shaped air duct to ensure smooth airflow from the fan 310 and maximize airflow.
