Description

Technical Field

[0001] The utility model relates to aromatherapy equipment, in particular to an aromatherapy atomization air duct structure and an aromatherapy device having the same. Background Art

[0002] Aromatherapy equipment usually uses the atomization principle to release fragrance. The atomized aromatherapy liquid gas will diffuse outward through the outlet, bringing a pleasant aromatic experience to the surrounding environment.

[0003] In related art, aromatherapy devices typically consist of a water tank and a cover. The water tank stores the aromatherapy liquid and houses an atomizer. The atomizer uses high-frequency vibration or heating to disperse the liquid into extremely fine mist particles, creating a scented mist. These mist particles remain suspended in the air, releasing the aroma molecules. The cover features a mist outlet for the atomized aroma vapor to escape.

[0004] In order to increase the power of the airflow and improve the diffusion efficiency, a common practice in the industry is to install a small fan inside the water tank. The convection generated by the fan can push the fragrance mist out of the mist outlet faster and farther, achieving a better diffusion effect. However, it should be noted that due to the presence of liquid in the water tank, the fan needs to be waterproof and sealed when installed inside the water tank. The fan is usually located at a higher position, and an air inlet for the fan to enter needs to be set on the cover. This built-in fan structure is not only complex in structure, such as the need for a complex waterproof structure, but also creates a turbulent and disordered airflow, which directly affects the delivery quality of the fragrance mist and reduces the diffusion effect of the fragrance mist.

[0064] The aromatherapy atomization air duct structure and the aromatherapy device having the same according to the embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0065] Reference Figures 1 to 6 As shown, the aromatherapy atomization air duct structure provided according to an embodiment of the present invention includes a liquid storage box 10, a fan 20, an air guide cap 30 and an atomization assembly 40.

[0066] Specifically, the liquid storage box 10 has a liquid storage chamber H10 for storing aromatherapy liquid. The liquid storage box 10 can be made of materials such as plastic and glass and can be configured in a circular, rectangular, waist-shaped, polygonal, or other shapes. An air supply column 101 is disposed within the liquid storage chamber H10. The air supply column 101 includes an air supply duct H11 extending vertically and independent of the liquid storage chamber H10. Preferably, the air supply column 101 and the liquid storage box 10 are integrally formed. The air supply duct H11 has an air inlet H111 at its lower end, located at the bottom of the liquid storage box 10, and an air outlet H112 at its upper end. In other words, the air inlet H111 is located outside the liquid storage chamber H10, allowing outside air to enter the air supply duct H11 within the air supply column 101 through the air inlet H111 and flow upwards out of the air outlet H112.

[0067] The fan 20 is disposed below the liquid storage box 10 and is configured to blow air into the air supply duct H11 through the air inlet H111, so that the airflow passes through the air supply duct H11 and is discharged from the air outlet H112. In other words, the fan 20 is disposed outside the liquid storage box 10 and is configured to blow air into the air inlet H111 to form an airflow that is then delivered to the air supply duct H11.

[0068] The air guide cap 30 is provided at the upper end of the air supply column 101 and covers the air outlet H112, thereby guiding the airflow from the air outlet H112 downwardly toward the liquid storage chamber H10. Since the air supply channel supplies air from bottom to top, without the air guide cap 30, the airflow from the air outlet H112 blows directly upward, and the upward airflow blows toward the atomized gas in the liquid storage chamber H10. To this end, the air guide cap 30 is provided at the upper end of the air supply column 101. The air guide cap 30 is used to change the direction of the airflow from the air outlet H112, causing the airflow to diffuse downwardly. In addition, the air guide cap 30 slows down the flow rate of the airflow and causes the airflow to diffuse downwardly in a circular shape. In this way, the circular downwardly diffused airflow is softer, and when it blows toward the atomized gas in the liquid storage chamber H10, the atomized gas can be more naturally dispersed to the outside of the liquid storage box 10.

[0069] The atomizer assembly 40 is disposed within the liquid storage chamber H10 and is used to atomize the liquid within the liquid storage chamber H10 to form an atomized vapor. The atomizer assembly 40 can utilize an ultrasonic atomizer chip, a heated atomizer element, or the like, and is installed at a lower position within the liquid storage chamber H10. When the atomizer assembly 40 is operating, it utilizes high-frequency vibration or heating to atomize the aromatherapy liquid within the liquid storage chamber H10 into fine mist particles, forming an atomized vapor. The atomized vapor is suspended within the liquid storage chamber H10 and naturally disperses under the influence of the airflow.

[0070] According to the aromatherapy atomization air duct structure provided by the embodiment of the present invention, an air supply duct H11 that is independent of the liquid storage chamber H10 is provided inside the liquid storage box 10, and the fan 20 is installed at the bottom of the liquid storage box 10, and supplies air to the air supply duct H11 through the air inlet H111, and then the air outlet H112 and the air guide cap 30 provided at the upper end of the air supply column 101 guide the air flow to the liquid storage chamber H10. In this way, the fan 20 is located outside the liquid storage chamber H10, avoiding the risk of liquid impregnating the fan 20, and fundamentally solving the waterproof and leak-proof problems of the traditional structure, and the safety and reliability of use are higher. At the same time, since the air supply duct H11 is separated from the liquid storage chamber H10 and is guided downward by the air guide cap 30, the air flow is smoother and more orderly, turbulence is reduced, and the misting effect is smoother and more natural. In addition, the air duct structure is compact and simple in design, takes up less space, and the compact design of the whole machine is conducive to product miniaturization.

[0071] Reference Figures 4 to 6As shown, in some embodiments of the present invention, the air guide cap 30 includes a cap body 301, which is arranged on the upper end of the air supply column 101, and the cap body 301 has a top wall 3011 and a peripheral wall 3012 connected to each other, and there is a predetermined gap between the top wall 3011 and the top surface of the air outlet H112.

[0072] The peripheral wall 3012 surrounds the outer side of the upper end of the air supply column 101 and defines an annular air guide cavity between the peripheral surface of the air supply column 101. The bottom of the annular air guide cavity is open to form an annular outlet for guiding the airflow downward to the liquid storage cavity H10.

[0073] With this air guide cap 30 structure, when air is ejected from the air outlet H112 of the air supply column 101, it is first blocked by the top wall 3011 and redirected, radiating outward. This radiating airflow then enters the annular air guide cavity through the predetermined gap. Confined and guided downward by the peripheral wall 3012, it ultimately ejects from below the annular outlet, forming a downward annular airflow that diffuses in all directions. This annular airflow has a wide coverage area and efficiently and evenly blows toward the liquid storage cavity H10, discharging the atomized vapor from the liquid storage cavity H10, thereby improving the diffusion performance of the atomized vapor.

[0074] Reference Figures 2 to 5 As shown, in one embodiment of the present invention, the air supply column 101 is arranged adjacent to the atomizing assembly 40 so that the air flow blown out by the air guide cap 30 is directed toward the area where the atomizing assembly 40 is located.

[0075] When the atomizer assembly 40 is in operation, it continuously atomizes the liquid in the liquid storage chamber H10 into fine water mist particles, forming atomized vapor that floats in the air. Although this atomized vapor easily diffuses due to air convection, it still exhibits a certain local enrichment distribution centered on the area where the atomizer assembly 40 is located.

[0076] In this embodiment, by arranging the air supply column 101 adjacent to the atomizing assembly 40 so that the ejected airflow is directed directly toward the area where the atomizing assembly 40 is located, the airflow can be utilized to the maximum extent to form a powerful pushing and dispersing effect on the atomized gas enriched in the area, thereby improving the utilization rate and transportation efficiency of the airflow and allowing the atomized gas to be fully diffused.

[0077] Reference Figure 3 and Figures 5 and 6As shown, in one embodiment of the present utility model, the liquid storage chamber H10 is further provided with a positioning portion 102, and the positioning portion 102 is provided on the liquid storage box 10 or the air supply column 101, and the air guide cap 30 also includes a plug-in portion 302, and the plug-in portion 302 is suitable for being plugged and fixed on the positioning portion 102; when the plug-in portion 302 is plugged into the positioning portion 102, the cap body 301 covers the upper end of the air supply column 101.

[0078] In order to achieve stable installation and precise positioning of the air guide cap 30, this embodiment provides a positioning portion 102 in the liquid storage chamber H10, and a matching plug-in portion 302 is provided on the air guide cap 30. The positioning portion 102 can be flexibly provided on the liquid storage box 10 or the air supply column 101 according to actual needs. The specific form of the positioning portion 102 can be a structure such as a protrusion, a groove or a snap. The plug-in portion 302 on the air guide cap 30 is designed to match the positioning portion 102. When the plug-in portion 302 is plugged into the positioning portion 102, the air guide cap 30 can be accurately covered on the upper end of the air supply column 101, ensuring the accuracy of the airflow guidance.

[0079] This plug-in positioning and installation structure is simple and convenient to install and remove, and ensures that the air guide cap 30 is in the desired position, improving the accuracy and stability of the installation of the air guide cap 30. In addition, it has strong adaptability and can replace air guide caps 30 of different sizes to accommodate air supply columns 101 of different sizes, providing greater flexibility in product design.

[0080] Reference Figure 5 and Figure 6 As shown, in one embodiment of the present invention, the positioning portion 102 is formed in a columnar shape, and a plug hole H12 is provided on the top of the positioning portion 102 , and the plug portion is adapted to the plug hole H12 and can be plugged in and connected.

[0081] In this embodiment, the positioning portion 102 is designed as a columnar structure with a plug hole H12 at its top. This corresponds to the plug portion on the air deflector 30, forming a pluggable connection. This design not only improves the stability of the connection but also increases the convenience of installation and removal. Installation is completed by simply aligning the plug portion with the plug hole H12 and gently pressing. Removal requires only a slight pull. This convenience greatly improves the cleaning and maintenance efficiency of the product.

[0082] Reference Figure 2 and Figures 5 and 6 As shown, in one embodiment of the present invention, the air deflector cap 30 further includes a carrier plate portion 303 , the cap body 301 is disposed on the carrier plate, and the plug-in portion 302 is disposed on the carrier plate portion 303 and extends downward from the bottom of the carrier plate.

[0083] This embodiment incorporates a carrier plate 303 as the foundation of the air deflector cap 30. The cap body 301 and positioning portion 102 are mounted on the carrier plate 303, creating a more stable overall structural design and enhancing the stability of the entire air deflector cap 30. Furthermore, the connector 302 is positioned at the bottom of the carrier plate 303 and extends downward, facilitating docking between the connector 302 and the positioning portion 102 and ensuring precise installation.

[0084] Reference Figures 2 to 6 As shown, in one embodiment of the present utility model, there are two air supply columns 101, the two air supply columns 101 are arranged at intervals, and the atomization assembly 40 is arranged between the two air supply columns 101; there are two cap bodies 301, the two cap bodies 301 correspond one-to-one to the two air supply columns 101, and each cap body 301 cover is arranged at the upper end of the corresponding air supply column 101.

[0085] In this embodiment, two air supply columns 101 are spaced apart, creating a space between them for mounting the atomizer assembly 40. Positioning the atomizer assembly 40 between the two air supply columns 101 fully leverages the forces of the two airflows, more effectively dispersing the atomized aroma particles throughout the liquid storage chamber H10 and then outward. This design significantly improves the efficiency and uniformity of aroma diffusion.

[0086] Preferably, the air supply column 101 is a cone with a diameter gradually decreasing from bottom to top. This conical structure allows the annular airflow blown downward by the air guide cap 30 to gradually diffuse to the surroundings, increasing the effective area of the annular airflow and thereby improving the diffusion effect on the atomized gas.

[0087] Reference Figures 2 to 3 and Figure 5 As shown, in some embodiments of the present invention, a light guide platform 103 is further provided in the liquid storage cavity H10, and a lamp trough extending into the light guide platform 103 is provided at the bottom of the liquid storage box 10, and a lamp board is provided in the lamp trough, and the light output direction of the lamp board is upward, so that the light emitted by the lamp board is emitted upward through the light guide platform 103. In specific applications, the light is projected upward through the atomized liquid to produce a pleasing visual effect. It is particularly worth mentioning that the lamp board can emit light of different colors, such as blue, yellow, etc. After passing through the atomized liquid, this colorful light can simulate the "smoke" effect of different colors, which greatly enhances the visual appeal and creates a variety of different atmospheres.

[0088] For example, a side wall of the liquid storage chamber H10 is provided with an identification portion 104 for identifying the maximum amount of water. The identification portion 104 may be a text mark and / or an identification structure, etc.

[0089] Reference Figures 1 to 6As shown, the aromatherapy diffuser according to an embodiment of the present invention includes a base 50, an air outlet cover 60 and the aromatherapy atomization air duct structure as described above. The bottom of the liquid storage box 10 is connected to the base 50 and defines an installation cavity. The air inlet is communicated with the installation cavity, and the fan 20 is arranged in the installation cavity.

[0090] The air outlet cover 60 is disposed on the liquid storage box 10 , and the air outlet cover 60 has an atomization outlet H60 communicating with the liquid storage chamber H10 for discharging the atomized gas in the liquid storage chamber H10 .

[0091] The aromatherapy diffuser operates as follows: First, the fan 20 rotates, generating airflow that accelerates and pushes it upward. Air is fed from the air inlet at the bottom of the liquid reservoir 10 into the air supply duct H11 of the air supply column 101, forming a flow. Next, the airflow exits the air outlet and, guided by the air guide cap 30, blows toward the area where the atomizer assembly 40 is located. Finally, driven by the continuous airflow, the atomized vapor is discharged through the atomizer outlet H60 provided on the air outlet cover 60. The discharged atomized vapor then diffuses into the surrounding environment.

[0092] For example, the base 50 typically includes a circuit board 70 for controlling the light panel, such as adjusting the color. A Bluetooth module can also be provided on the circuit board 70 for connecting to a mobile device such as a cell phone, enabling wireless control of the aromatherapy diffuser, thereby enhancing the user experience. Furthermore, the base 50 can include several through-holes for air intake and moisture removal, preventing moisture accumulation within the base 50 from damaging electrical components such as the circuit board 70 and fan 20, thereby improving reliability and safety.

[0093] The aroma diffuser provided by the present invention incorporates the aforementioned aroma atomizing air duct structure, fundamentally resolving the waterproofing and leak-proofing issues of conventional structures, enhancing safety and reliability. Furthermore, airflow is smoother and more orderly, reducing turbulence and resulting in a more fluid and natural misting effect. Furthermore, the air duct structure is compact and simple, taking up little space, and the compact design of the entire device facilitates product miniaturization.
