[0028] Please refer to Figures 1 to 5, an aromatherapy device 10 provided by an embodiment of the present utility model includes an aromatherapy main body 12 and a blower 14. The aromatherapy main body 12 includes an aroma storage structure 16 and a fragrance diffusion chamber 18 connected to the aroma storage structure 16. The aroma storage structure 16 can generate aromatherapy gas and enter the fragrance diffusion chamber 18. The blower 14 is arranged in the fragrance diffusion chamber 18. A fragrance diffusion part 20 is provided on the circumferential side wall of the fragrance diffusion chamber 18, and the fragrance diffusion part 20 communicates with the inside of the fragrance diffusion chamber 18 and the outside of the aromatherapy device 10. When the blower 14 works, it can drive the outside air flow into the fragrance diffusion chamber 18 and discharge it from the fragrance diffusion part 20. During the process of the air flow flowing from the fragrance diffusion chamber 18 to the fragrance diffusion part 20, it will drive the aromatherapy gas in the fragrance diffusion chamber 18 to flow together, and finally discharge it from the fragrance diffusion part 20 to the outside of the aromatherapy device 10. The blower 14 can accelerate the flow rate of the air flow, so that the aromatherapy gas can flow from the fragrance diffusion chamber 18 to the outside of the aromatherapy device 10 faster, improving the diffusion speed of the aromatherapy gas to the outside. Moreover, the fragrance diffusion part 20 is arranged on the circumferential side wall of the fragrance diffusion chamber 18. Compared with being arranged on one axial side of the fragrance diffusion chamber 18, it is beneficial to increase the area of the fragrance diffusion part 20 to improve the diffusion speed of the aromatherapy gas to the outside.

[0029] The usage scenario of the aromatherapy device 10 is not limited. It can be placed on the table for use or placed in the vehicle for use. In this application, the aromatherapy device 10 is generally cylindrical in shape. It can be placed in the cup holder on the car console. The fragrance diffusion part 20 is located outside the cup holder. The aromatherapy gas can be diffused into the vehicle air through the fragrance diffusion part 20 to purify the vehicle air and refresh the driver. For the cylindrical aromatherapy device 10, the surface area of its circumferential side is larger than that of one axial side. Therefore, setting the fragrance diffusion part 20 on the circumferential side of the aromatherapy main body 12 is beneficial to increase the area of the fragrance diffusion part 20.

[0030] The fragrance diffusion part 20 is located on the circumferential outer side of the aromatherapy main body 12. Therefore, during the use of the aromatherapy device 10, the fragrance diffusion part 20 can be oriented towards the user. After the aromatherapy gas is discharged from the fragrance diffusion part 20, it can directly blow towards the user, enabling the user to perceive the aromatherapy gas faster.

[0031] The number of the fragrance diffusion parts 20 is multiple. The multiple fragrance diffusion parts 20 are arranged at intervals along the circumference of the aromatherapy main body 12 to increase the area of the fragrance diffusion part 20, facilitating the blower 14 to drive the circulation of the aromatherapy gas. The aromatherapy gas is not likely to generate turbulent flow in the aromatherapy main body 20, enhancing the diffusion speed of the aromatherapy gas to the outside. It should be noted that in this solution, multiple means two or more. When there are two fragrance diffusion parts 20, the two fragrance diffusion parts 20 are arranged on the opposite sides of the side wall of the aromatherapy main body 12.

[0032] Preferably, at least two of the plurality of fragrance diffusing parts 20 are arranged on opposite sides along the radial direction of the aromatherapy main body 12, that is, at least two fragrance diffusing parts 20 are distributed on the radial two sides of the aromatherapy main body 12, so that when the blower 14 is in a non-operating state, the external air flow can enter the fragrance diffusion cavity 18 from one of the fragrance diffusing parts 20 and then discharge from the other opposite fragrance diffusing part 20, forming a convection effect. During the air flow process, the fragrance gas can also be driven to flow, so as to improve the natural diffusion speed of the fragrance gas. Specifically, the number of the fragrance diffusing parts 20 is two, and the two fragrance diffusing parts 20 are symmetrically arranged along the radial direction of the fragrance diffusion cavity 18.

[0033] The specific type of the blower 14 is not limited, such as an axial flow blower 14, a centrifugal blower 14, etc. In this embodiment, the blower 14 is an axial flow blower 14, and the air outlet part of the blower 14 faces the fragrance storage structure 16, so that the air flow can directly blow towards the fragrance storage structure 16 under the action of the blower 14. The fragrance diffusing parts 20 are distributed on the radial two sides of the aromatherapy main body 12. When the air flow blows towards the fragrance diffusion structure 16, it drives the fragrance gas to flow out towards the two opposite ends of the aromatherapy main body 12, and the gas flow is relatively smooth, which can take away more fragrance gas, thereby improving the air purification and refreshing effects of the aromatherapy device 10.

[0034] In one embodiment, the aromatherapy main body 12 is provided with an air inlet part 22 communicating with the fragrance diffusion cavity 18, and the air inlet part 22 is located on one axial side of the fragrance diffusion cavity 18. The aromatherapy device 10 takes in air from the axial direction of the aromatherapy main body 12 and discharges air from the circumferential direction of the aromatherapy main body 12. The air intake and air outlet are not in the same direction, preventing the air intake and air outlet from interfering with each other.

[0035] The air inlet part 22 can be located at the axial top of the aromatherapy main body 12 or at the axial bottom of the aromatherapy main body 12. In this embodiment, the air inlet part 22 is arranged at the axial top of the aromatherapy main body 12, and the blower 14 is arranged close to the air inlet part 22.

[0036] In one embodiment, the aromatherapy main body 12 includes an aromatherapy cover 24. A fragrance diffusion cavity 18 is formed inside the aromatherapy cover 24. An air intake part 22 and a fragrance diffusion part 20 are arranged on the aromatherapy cover 24. The blower 14 is located inside the aromatherapy cover 24. The aromatherapy cover 24 is covered on the fragrance storage structure 16. The aromatherapy cover 24 is detachably connected to the fragrance storage structure 16, which is convenient for replacing the fragrance storage structure 16. The air intake part 22 is arranged at the top of the aromatherapy cover 24, and the fragrance diffusion part 20 is arranged at the circumferential side part of the aromatherapy cover 24. The blower 14 is fixedly installed inside the aromatherapy cover 24 and is arranged close to the top of the aromatherapy cover 24. So that the blower 14 can blow downward towards the fragrance storage structure 16, and the fragrance automatically flows out towards the opposite sides of the aromatherapy cover. The fragrance gas circulation path is smooth and the fragrance diffusion effect is good. When the blower 14 works, the outside air can enter the fragrance diffusion cavity 18 through the air intake part 22 at the top of the aromatherapy cover 24, and is blown towards the fragrance storage structure 16 under the action of the blower 14. After being blocked by the fragrance storage structure 16, the air changes its movement direction and is discharged from the circumferential fragrance diffusion part 20.

[0037] In other embodiments, the fragrance storage structure 16 can also be arranged inside the aromatherapy cover 24. For example, the fragrance storage structure 16 can be a fragrance block, a fragrance paste, an essential oil box, etc. stored inside the aromatherapy cover 24. The fragrance storage structure 16 can also be accommodated inside the aromatherapy cover 24 and is arranged close to the bottom of the aromatherapy cover 24.

[0038] Each fragrance diffusion part 20 includes a plurality of fragrance diffusion openings 26 arranged at the circumferential side part of the aromatherapy cover 24. The plurality of fragrance diffusion openings 26 are arranged at intervals along the circumference of the aromatherapy cover 24.

[0039] Preferably, the fragrance diffusion openings 26 extend along the axial direction of the aromatherapy cover. The fragrance diffusion openings 26 are arranged along the circumference and extend along the axial direction. The arrangement direction and the extension direction are not in the same direction and will not interfere with each other, which is beneficial to increasing the area of the fragrance diffusion openings 26, thereby increasing the area of the fragrance diffusion part 20 and facilitating the outward diffusion of the fragrance gas.

[0040] The outer side of the aroma diffuser cover 24 is provided with a plurality of convex strips 28. The plurality of convex strips 28 are arranged at intervals along the circumferential direction of the aroma diffuser cover 24. A fragrance dispersion port 26 is formed between adjacent convex strips 28. The plurality of fragrance dispersion ports 26 constitute the fragrance dispersion part 20. In this embodiment, the plurality of convex strips 28 are arranged to be inclined away from the radial direction of the aroma diffuser cover 24, and the inclination direction is known. It not only has a special modeling effect, but also makes the adjacent convex strips 28 form a fragrance dispersion port 26 with a guiding shape, which is beneficial to controlling the shape and direction of the aroma gas diffusing out of the fragrance dispersion port 26 to meet different needs. In some embodiments, the fragrance dispersion port 26 extends along the axial direction of the aroma diffuser cover 24, that is, along the height direction of the aroma diffuser cover 24. The fragrance dispersion port 26 extends to both the top and bottom ends of the aroma diffuser cover 24; it should be noted that the top and bottom, for example, the aroma diffuser cover 24 is evenly divided into three parts in the height direction, and the top, middle, and bottom are connected in sequence; the fragrance dispersion port 26 extends to both the top and bottom ends of the aroma diffuser cover 24. For example, the fragrance dispersion port 26 is arranged in the middle and extends along the height of the aroma diffuser cover 24, and the extension height exceeds the middle part and reaches the top and bottom. Of course, when the fragrance dispersion port 26 extends infinitely close to the top surface and bottom surface of the aroma diffuser cover 24, the area of the fragrance dispersion port 26 is larger and the fragrance dispersion effect is better.

[0041] The air intake part 22 includes a plurality of air intake ports 30 provided on the aroma diffuser cover 24. The plurality of air intake ports 30 are arranged at intervals along the circumferential direction of the aroma diffuser cover 24. By providing the plurality of air intake ports 30, it is beneficial to increase the area of the air intake part 22, thereby increasing the air intake volume.

[0042] In this embodiment, the plurality of air intake ports 30 are arranged in a radial pattern, that is, the size of the air intake ports 30 gradually decreases from the outside to the inside, so as to set a larger number of air intake ports 30.

[0043] The air intake ports 30 are provided through the top of the aroma diffuser cover 24. A flow guiding surface 32 is provided on the aroma diffuser cover 24 corresponding to each air intake port 30. The flow guiding surface 32 extends obliquely downward from top to bottom. Understandably, the flow guiding surface 32 extends obliquely downward from the periphery of the aroma diffuser cover 24 towards the center of the aroma diffuser cover 24. When the external air flow enters the fragrance dispersion cavity 18 through the air intake ports 30 from the top of the aroma diffuser cover 24, when the air flow moves downward to the flow guiding surface 32, the air flow will flow downward along the flow guiding surface 32 and enter the fragrance dispersion cavity 18, forming a flow guiding effect to increase the air intake volume.

[0044] In one embodiment, the aroma diffusing cover 24 includes an end cap 34 and a surrounding wall 36 disposed around the outer periphery of the end cap 34. The end cap 34 is disposed at the top of the surrounding wall 36. The aroma diffusing cavity 18 is located inside the surrounding wall 36. The blower 14 is fixedly installed on the inner side of the surrounding wall 36 and is disposed close to the end cap 34. The air inlet portion 22 penetrates through the end cap 34, the aroma diffusing portion 20 penetrates through the surrounding wall 36, and the aroma storage structure 16 is disposed on the side of the surrounding wall 36 away from the end cap 34. When the blower 14 operates, the outside air enters the aroma diffusing cavity 18 through the air inlet portion 22 on the end cap 34 at the top of the aroma diffusing device 10, and flows towards the aroma storage structure 16. After moving to the aroma storage structure 16, it is blocked by the aroma storage structure 16 and changes the flow direction, and finally is discharged from the aroma diffusing portion 20 on the surrounding wall 36.

[0045] The aroma diffusing cover 24 further includes a connecting seat 38. The connecting seat 38 is disposed on the side of the surrounding wall 36 away from the end cap 34. The aroma storage structure 16 is connected to the connecting seat 38. A battery 39 is installed on the connecting seat 38. The battery 39 is electrically connected to the blower 14 to provide electrical energy for the operation of the blower 14, breaking away from the limitation of an external power supply and facilitating user use.

[0046] In one embodiment, the aroma storage structure 16 includes a liquid storage bottle 40, a liquid absorbing member 42, and a liquid storing member 44. The liquid storage bottle 40 is connected to the aroma diffusing cover 24. The liquid storage bottle 40 has a liquid storage space to accommodate aroma essential oil. One end of the liquid absorbing member 42 is located inside the liquid storage bottle 40 and is in contact with the aroma essential oil. The other end of the liquid absorbing member 42 is connected to the liquid storing member 44. The liquid storing member 44 is located inside the aroma diffusing cavity 18. The air outlet portion of the blower 14 faces the liquid storing member 44. The liquid absorbing member 42 can absorb the aroma essential oil in the liquid storage bottle 40 and transfer it to the liquid storing member 44. The liquid storing member 44 can store the aroma essential oil. Since the liquid storing member 44 is located inside the aroma diffusing cavity 18, the aroma gas formed by the volatilization of the aroma essential oil on the liquid storing member 44 will automatically be inside the aroma diffusing cavity 18.

[0047] Specifically, the liquid absorbing member 42 is a cotton swab, and the liquid storing member 44 is a cotton ball. Both the cotton swab and the cotton ball have the effect of absorbing and storing liquid, so that the aroma essential oil in the liquid storage bottle 40 can be transferred to the liquid storing member 44 inside the aroma diffusing cavity 18 through the liquid absorbing member 42, and the aroma gas generated by the volatilization of the aroma essential oil can be directly diffused into the aroma diffusing cavity 18.

[0048] The above embodiments are only the preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention belong to the scope of protection required by the present invention.
