[0064] With the continuous development of society and the continuous progress of technology, people's living standards have gradually improved, and aromatherapy products have gradually become one of the most commonly used household appliances in people's daily lives.

[0065] Currently, most existing aromatherapy products use jet atomization liquid sprays (there are also problems of bacterial growth in the atomization equipment) or paste-like fragrance burning diffusers. Among them, the diffuser using jet atomization is based on the Venturi jet principle. Compressed air forms a high-speed airflow through a small nozzle, and the negative pressure generated drives the liquid or other fluids to be sprayed onto an obstacle together. Under high-speed impact, it splashes around and makes the droplets turn into mist-like particles and spray out from the air outlet pipe. However, this type of equipment is prone to oil leakage and seepage, etc., which can easily lead to liquid entering the internal part of the equipment and damaging the circuit, reducing the service life of the equipment.

[0066] And the above-mentioned paste-like fragrance burning diffuser must add volatile substances when in use. However, due to containing chemical components, it will have an impact on human health during long-term use, and the burning diffuser has a risk of easily causing a fire. Therefore, existing aromatherapy devices all have problems of poor safety.

[0067] To solve the above problems, the present application proposes an aromatherapy device 100, which can at least solve the problem of poor safety existing in the existing aromatherapy device 100.

[0068] In the overall design, as Figures 1 - 11 shown, the aromatherapy device 100 includes a housing 10, a fan assembly 20 and an aromatherapy sheet 30. Among them, a first air duct 111 and a second air duct 121 are provided on the housing 10. The fan assembly 20 has a frame 21 and fan blades 22. The frame 21 is installed on the housing 10, and the frame 21 is connected to the first air duct 111 and the second air duct 121 to form a ventilation cavity for air flow and allowing the air flow to pass through the housing 10. The fan blades 22 are located inside the ventilation cavity. The aromatherapy sheet 30 is provided on the housing 10 and located at the air outlet of the ventilation cavity.

[0069] Specifically, by providing the first air duct 111 and the second air duct 121 on the housing 10 and being able to cooperate with the frame 21 of the fan assembly 20 to form a ventilation cavity, the ventilation cavity can allow air flow and enable the air flow to penetrate the housing 10. At the same time, an aromatherapy sheet 30 is provided at the air outlet of the ventilation cavity. The fan assembly 20 drives the air flow to enter from the air inlet and discharge from the air outlet, and when flowing through the aromatherapy sheet 30, it can drive the aromatherapy gas to flow out along with the air flow, thereby achieving the effect of diffusing fragrance, helping to avoid phenomena such as oil leakage and seepage, as well as the volatilization of chemical substances, and effectively improving the convenience and safety of the aromatherapy device 100 during use.

[0070] It should be understood that in this embodiment, the frame 21 of the fan assembly 20 is installed inside the housing 10. At the same time, the first air duct 111 and the second air duct 121 are provided on the housing 10 at intervals. The first air duct 111 and the second air duct 121 are respectively arranged on opposite sides of the frame 21 and are connected to the ventilation slots 211 of the frame 21 to form a ventilation cavity that can penetrate the housing 10. Thus, it can be seen that the housing 10 can provide an installation foundation for the fan assembly 20 and cooperate with the frame 21 to form a ventilation cavity for air flow. Moreover, the cooperation between the housing 10 and the frame 21 can form a shorter ventilation path, thereby ensuring the air flow effect in the ventilation cavity.

[0071] It should be noted that the fan assembly 20 in this embodiment is an axial flow fan, and the fan blades 22 of the axial flow fan can push the air to flow in the same direction as its axis. When the axial flow fan is working, the flow direction of most of the air flow is parallel to the axis, that is, in the axial direction. Since the axial flow fan has a compact structure, it can save a lot of space and is convenient to install. Therefore, using the axial flow fan as the fan assembly 20 can effectively improve the convenience of the fan assembly 20.

[0072] As Figure 3 and Figure 10As shown in the figure, the fan assembly 20 includes a frame 21, a driving part, and a fan blade 22. Among them, the frame 21 is integrally square-shaped, and an annular ventilation groove 211 is formed inside the frame 21. The side wall of the ventilation groove 211 is connected to the side walls of the first air duct 111 and the second air duct 121 to form a ventilation cavity. At the same time, a support plate 212 is provided on the frame 21. The support plate 212 is located at one end of the ventilation groove 211. A driving member is provided on the support plate 212, and a fan blade 22 is provided at the output end of the driving member.

[0073] In addition, the aroma diffuser sheet 30 in this embodiment is made of a high-density molecular material, which has the characteristics of fast penetration and slow volatilization, and can effectively extend the service life of the aroma diffuser sheet 30. At the same time, a number of ventilation holes are provided on the aroma diffuser sheet 30 to increase the contact area between the air flow and the aroma diffuser sheet 30, thereby ensuring the aroma diffusion effect.

[0074] It should be noted that the aroma diffuser sheet 30 can be used as a consumable, which helps to avoid the problem of bacterial growth in traditional atomizing aroma diffusers. Since the aroma diffuser sheet 30 is a consumable, the aroma diffuser sheet 30 is detachably installed in the housing 10 to effectively enable the aroma diffuser sheet 30 to be replaced at any time, which helps to improve the applicability of the aroma diffuser sheet 30, so that users can replace different fragrance types according to different scene atmospheres.

[0075] Furthermore, the housing 10 includes a first housing 11 and a second housing 12. Among them, a first air duct 111 and a first receiving groove 113 surrounding the first air duct 111 are formed on the first housing 11. A second air duct 121 and a second receiving groove 123 surrounding the second air duct 121 are formed on the second housing 12.

[0076] The second housing 12 is buckled with the first housing 11, and the first receiving groove 113 and the second receiving groove 123 form a receiving cavity, which is arranged radially outside the ventilation cavity.

[0077] Specifically, by setting the housing 10 as the first housing 11 and the second housing 12, the installation convenience of the fan assembly 20 can be effectively improved, which helps to reduce the assembly difficulty of the aroma diffuser device 100. At the same time, by providing the first receiving groove 113 and the second receiving groove 123, they are used to fix the frame 21 and ensure the cooperation and connection between the ventilation groove 211 of the frame 21 and the first air duct 111 and the second air duct 121. Moreover, by arranging the receiving cavity formed by the first receiving groove 113 and the second receiving groove 123 radially outside the ventilation cavity, the space utilization rate of the aroma diffuser device 100 can be effectively improved, thereby ensuring the aesthetics and convenience of the aroma diffuser device 100.

[0078] Such as Figure 3 and Figure 6As shown, a first cavity recessed in a first direction is formed on a first housing 11. The first direction is the direction in which the first housing 11 faces away from the second housing 12. An annular reinforcing rib 101 is disposed in the middle of the first cavity. The reinforcing rib 101 can divide the first cavity into a first receiving groove 113 and a first air duct 111. The first air duct 111 has a first ventilation opening 112 formed at the bottom.

[0079] Still as Figure 6 shown, a plurality of mounting posts 102 and a plurality of reinforcing ribs 101 are disposed in the first receiving groove 113. Among them, some of the mounting posts 102 are used for the fixed installation of the second housing 12, and the other part of the mounting posts 102 are used for the mounting and fixing of the frame 21 and the following circuit board 50. At the same time, at least two reinforcing ribs 101 cooperate to form a fixing groove for mounting and fixing the following negative ion generating assembly 80 and power supply assembly 70. At least four reinforcing ribs 101 cooperate to form a limiting groove for accommodating and mounting the frame 21 in cooperation with the mounting posts 102. In addition, at least two reinforcing ribs 101 provide a support base for the following charging plug 72 and control switch 51.

[0080] It should be noted that the first housing 11 is injection molded. By arranging the reinforcing rib 101 inside the first cavity, the structural strength of the first housing 11 can be effectively improved, and a mounting or support base is provided for other components, ensuring the convenience of mounting other components.

[0081] In this embodiment, as Figure 3 、 Figure 5 and Figure 7 shown, a second cavity recessed in a second direction is formed on a second housing 12. The second direction is the direction in which the second housing 12 faces away from the first housing 11. An annular reinforcing rib 101 is disposed in the middle of the second cavity. The reinforcing rib 101 can divide the second cavity into a second receiving groove 123 and a second air duct 121. The second air duct 121 has a second ventilation opening 122 formed at the bottom. A plurality of reinforcing ribs 101 are disposed in the second receiving groove 123 to improve the structural strength of the second housing 12. At the same time, a plurality of mounting posts 102 are disposed in the second receiving groove 123 for the fitting connection between the first housing 11 and the second housing 12.

[0082] It should be noted that a limiting post 124 is also disposed in the second receiving groove 123. One end of the limiting post 124 away from the second housing 12 can extend into the interior of the first housing 11 and be fitted and connected with the avoidance structure of the following circuit board 50, thereby ensuring the assembly efficiency of the aromatherapy device 100.

[0083] In addition, the second housing 12 is injection-molded, and the edge of the second housing 12 abuts against a part of the reinforcing ribs 101 on the first housing 11 to ensure the connection strength between the second housing 12 and the first housing 11. At the same time, further, the connection surface between the edge of the second housing 12 and the reinforcing rib 101 is stepped, which helps to further improve the convenience of connecting the second housing 12 and the first housing 11.

[0084] It should be understood that the housing 10 as a whole has a quasi-cylindrical structure. Among them, the axial dimension of the housing 10 is smaller than the radial dimension of the housing 10. The housing 10 includes a first housing 11 and a second housing 12. The first housing 11 and the second housing 12 are snap-connected and connected together by a screw member. At this time, the first air duct 111 and the second air duct 121 are arranged at intervals, and a frame 21 is interposed between the first air duct 111 and the second air duct 121 to form a ventilation cavity. At the same time, the first receiving groove 113 and the second receiving groove 123 cooperate to form a receiving cavity, and the receiving cavity is arranged around the radial outside of the ventilation cavity.

[0085] Further, the aromatherapy device 100 further includes a cover body 13. Among them, the cover body 13 is arranged on the housing 10. A through hole 131 is provided on the cover body 13, and a receiving space for receiving the aromatherapy tablet 30 is formed by the cooperation of the cover body 13 and the housing 10.

[0086] Specifically, by providing the cover body 13 to be able to cooperate with the second housing 12 to form a receiving space for receiving the aromatherapy tablet 30, it is ensured that the gas output from the ventilation cavity can flow through the aromatherapy tablet 30 and achieve aroma diffusion. The setting of the cover body 13 can also effectively protect the second housing 12 and shield the screw member on the second housing 12, ensuring the aesthetics of the aromatherapy device 100. At the same time, the setting of the cover body 13 can also cooperate with the following light-emitting components to further improve the aesthetics of the aromatherapy device 100.

[0087] It should be understood that as Figure 3 , Figure 4 , Figure 5 and Figure 8 shown, a cover body 13 is arranged on the side of the second housing 12 away from the first housing 11. The cover body 13 is snap-connected to the second housing 12. At the same time, the cover body 13 is arranged to abut against the first housing 11. By installing the cover body 13 in a snap-connection manner and making the cover body 13 abut against the first housing 11, the exposure of screw members or other components can be effectively reduced, thereby ensuring the aesthetics of the aromatherapy device 100. Preferably, the abutting surface between the first housing 11 and the cover body 13 is stepped to improve the sealing performance of the aromatherapy device 100, thereby preventing external impurities (liquids) from entering the receiving cavity.

[0088] It should be noted that as Figure 1 , Figure 2 , Figure 3 andFigure 5 As shown, the outer diameter of the first housing 11 is the same as that of the cover 13, and the second housing 12 is disposed inside the cover 13, that is, the outer diameter of the second housing 12 is smaller than that of the first housing 11. This arrangement can further improve the aesthetics of the aromatherapy device 100.

[0089] In addition, avoidance grooves 104 are provided on the first housing 11, the second housing 12, and the cover 13. When the first housing 11 and the second housing 12 are snap-connected, the avoidance grooves 104 on the first housing 11 and the avoidance grooves 104 on the second housing 12 are cooperatively connected to form a connection hole connected to the outside. This connection hole can be used to accommodate the control button 14 or the charging plug 72. At the same time, when the cover 13 abuts against the first housing 11, the avoidance groove 104 on the cover 13, the avoidance groove 104 on the first housing 11, and the control button 14 or the charging plug 72 are smoothly connected to ensure the aesthetics of the aromatherapy device 100.

[0090] Furthermore, the aromatherapy device 100 further includes a mounting member 40. The mounting member 40 is embedded in the cover 13 and accommodated in the accommodation space. The mounting member 40 has an accommodation groove 42, and an aromatherapy sheet 30 is disposed in the accommodation groove 42.

[0091] Specifically, by providing the mounting member 40 for accommodating the aromatherapy sheet 30 and enabling the aromatherapy sheet 30 to be fixed in the accommodation space together with the mounting member 40, it helps to improve the installation efficiency of the aromatherapy sheet 30 and ensure the installation accuracy of the aromatherapy sheet 30, that is, to ensure that the gas output from the ventilation cavity can diffuse into the external environment through the aromatherapy sheet 30. At the same time, the setting of the mounting member 40 also helps to reduce the pollution of the aromatherapy sheet 30 by the external environment and ensure the service life and use effect of the aromatherapy sheet 30.

[0092] It should be understood that, as Figures 3 - 5 、 Figure 8 and Figure 11 shown, a clamping protrusion 132 is provided on the inner side of the through hole 131 of the cover 13. At the same time, a clamping groove 43 is formed on the outer side of the mounting member 40. The clamping protrusion 132 can be embedded into the clamping groove 43, and the mounting member 40 can be rotated to prevent the mounting member 40 from disengaging from the accommodation space. This arrangement not only simplifies the installation difficulty of the mounting member 40 but also ensures the connection effect between the mounting member 40 and the cover 13. Moreover, one end of the mounting member 40 close to the second housing 12 abuts against or presses against the second housing 12, thereby further ensuring the fixing effect of the mounting member 40. In addition, the embedding of the mounting member 40 can cooperate with the cover 13 to ensure the aesthetics of the aromatherapy device 100.

[0093] As Figure 3 and Figure 11As shown, the mounting member 40 has a receiving groove 42 that is recessed in the third direction, which is the direction in which the mounting member 40 faces away from the cover body 13. The third direction, the second direction, and the first direction are all on the same straight line. The setting of the receiving groove 42 can cooperate with the second housing 12 to form a fixing cavity for receiving the aromatherapy tablet 30, which can effectively ensure the installation effect of the aromatherapy tablet 30, prevent the aromatherapy tablet 30 from detaching from the receiving space. At the same time, it also helps to ensure the installation accuracy of the aromatherapy tablet 30 and prevent the aromatherapy tablet 30 from blocking the second ventilation opening 122.

[0094] It should be noted that a number of third ventilation openings 41 are provided on the mounting member 40, and the shapes of the third ventilation openings 41 correspond one-to-one to the above-mentioned second ventilation openings 122. At the same time, a number of through holes are provided on the aromatherapy tablet 30, and the shapes of the through holes correspond one-to-one to the second ventilation openings 122. In this way, it can effectively ensure that the output gas in the ventilation cavity can flow through the second ventilation holes, the through holes of the aromatherapy tablet 30, and the ventilation holes of the mounting member 40 in sequence, so as to achieve the purpose of fragrance diffusion. Among them, the setting of the through holes can effectively increase the contact area between the aromatherapy tablet 30 and the outside, and ensure the diffusion effect of the fragrance.

[0095] Furthermore, the aromatherapy device 100 further includes a circuit board 50 and a lighting component. Among them, the circuit board 50 is sleeved on the radial outer side of the ventilation cavity, and the circuit board 50 is electrically connected to the fan assembly 20.

[0096] Specifically, by setting the circuit board 50 to cooperate with the fan assembly 20, the start and stop of the fan assembly 20 can be realized, thereby improving the controllability and convenience of the aromatherapy device 100. At the same time, sleeving the circuit board 50 on the radial outer side of the ventilation cavity can further improve the utilization rate of the accommodation cavity, thereby improving the space utilization rate of the aromatherapy device 100. In addition, the setting of the circuit board 50 can also provide a control basis for the setting of the following several components, thereby enriching the functions of the aromatherapy device 100, and further helping to improve the use effect of the aromatherapy device 100.

[0097] It should be understood that, as Figure 3 and Figure 9 shown, a relief hole is provided in the middle of the circuit board 50, and the shape of the relief hole is the same as the shape of the frame 21 of the fan assembly 20. When the circuit board 50 is fixed to the first housing 11, the inner wall of the relief hole abuts against the outer side surface or the reinforcing rib 101 of the frame 21 to ensure the installation accuracy of the circuit board 50. At the same time, a relief structure is provided at one end of the circuit board 50, and the relief structure can be connected with the limit post 124 of the second housing 12, so as to further ensure the installation accuracy of the circuit board 50 and improve the installation efficiency of the circuit board 50. Preferably, the relief structure can be set as a relief opening, and the relief opening abuts against the outer peripheral surface of the limit post 124.

[0098] It should be noted that a number of mounting holes are provided on the circuit board 50. By passing through the mounting holes and screwing the screw members onto the mounting posts 102, the circuit board 50 can be fixed to the first housing 11, which helps to improve the mounting stability of the circuit board 50.

[0099] In addition, a control switch 51 is further provided on the circuit board 50. The setting of the control switch 51 can at least start or close the fan assembly 20 to ensure the use effect of the aromatherapy device 100. The number of the control switches 51 is at least one. Correspondingly, the number of the control buttons 14 is multiple. The control switch 51 and the control button 14 are in abutting contact, and the control switch 51 and the control button 14 are in one-to-one correspondence.

[0100] Furthermore, as Figure 3 shown, the aromatherapy device 100 further includes a light-emitting assembly. The light-emitting assembly includes at least two light-emitting elements 60, and the at least two light-emitting elements 60 are arranged at intervals along the circumference of the ventilation cavity. At the same time, the second housing 12 is made of a transparent material, and a number of light-transmitting holes 133 are formed on the cover body 13. The number of light-transmitting holes 133 is arranged along a number of preset paths, and along the preset path, the aperture of the light-transmitting hole 133 first increases and then decreases.

[0101] Specifically, by providing the light-emitting assembly to cooperate with the second housing 12 and the cover body 13, a light source can be provided for the user, which helps to enrich the functions of the aromatherapy device 100 and improve the use effect of the aromatherapy device 100. By limiting the number and installation positions of the light-emitting elements 60, the light can be irradiated onto the outside of the aromatherapy device 100 more evenly, thereby ensuring the irradiation effect of the aromatherapy device 100. At the same time, by limiting the shapes and positions of the light-transmitting holes 133, the aesthetic property of the light irradiation can be effectively improved, thereby further improving the irradiation effect of the light-emitting assembly and the use effect of the aromatherapy device 100.

[0102] It should be understood that in this embodiment, the number of the light-emitting elements 60 is four. The four light-emitting elements 60 are respectively arranged on the circuit board 50 and are arranged at intervals along the circumference of the ventilation cavity (equally spaced). In this way, the uniformity of the light irradiation can be effectively ensured. Of course, in addition, the number of the light-emitting elements 60 can also be three, five, six, etc. However, arranging four light-emitting elements 60 can not only ensure the light effect, but also has the optimal power consumption.

[0103] It should be noted that the light-emitting elements 60 are all LED lights. Since the LED lights can be embedded on the circuit board 50 and have a small size, using LED as the light-emitting element 60 can effectively reduce the space occupancy rate of the light-emitting element 60. At the same time, the LED lights also have the advantages of high efficiency, energy saving, long life, environmental protection, durability, rich colors and low heat, which helps to improve the use effect of the aromatherapy device 100.

[0104] It should be understood that the transparent material used for the second housing 12 enables the light source emitted by the LED lamp to irradiate outside the second housing 12. At the same time, a plurality of light-transmitting holes 133 are provided on the cover 13, so that the light source emitted by the LED lamp can irradiate outside the cover 13 through the light-transmitting holes 133. At this time, by defining the structure and quantity of the light-transmitting holes 133, the beam shape and quantity of the aromatherapy lamp can be effectively guaranteed, and thus the use effect of the aromatherapy device 100 can be guaranteed.

[0105] As Figure 4 and Figure 8 shown, a plurality of light-transmitting holes 133 are arranged along a plurality of preset paths. Among them, the preset path can be a straight line or a curve. Preferably, the preset path is an arc, and a plurality of preset paths are arranged around and spaced apart with the through hole 131 as the center, so as to form a nebula-like structure. Along any preset path, the aperture of the light-transmitting hole 133 first increases and then decreases. With such a setting, the colorful effect of the light can be further improved.

[0106] It should be noted that, as Figure 3 、 Figure 4 and Figure 8 shown, an installation area is formed on the cover 13 by means of protrusions or depressions, and a plurality of light-transmitting holes 133 arranged along the preset path are provided in the installation area. The setting of the installation area can further cooperate with the light-transmitting holes 133 arranged along the preset path to improve the structure of the light or the aromatherapy device 100.

[0107] Furthermore, as Figure 3 、 Figure 5 and Figure 6 shown, the aromatherapy device 100 further includes a power supply assembly 70. The power supply assembly 70 is arranged in the accommodation cavity, and the power supply assembly 70 is connected to an external power supply through a circuit board 50.

[0108] Specifically, by setting the power supply assembly 70, the use of the aromatherapy device 100 is no longer restricted by the environment (electricity), and in cooperation with the structure of the aromatherapy device 100, the convenience of the aromatherapy device 100 can be effectively improved. At the same time, the power supply assembly 70 is connected to the external power supply through the circuit board 50, which can further realize the use effect of the fan assembly 20 and guarantee the use duration of the aromatherapy device 100.

[0109] It should be understood that in this embodiment, the power supply assembly 70 includes a battery 71 and a charging plug 72. Among them, two of the reinforcing ribs 101 on the first housing 11 are arranged at intervals for mounting the battery 71 on the first housing 11.

[0110] It should be noted that the battery 71 is a rechargeable battery 71, and the capacity of the battery 71 is at least 600 mA, so as to be able to continuously output an actual battery life of up to 14 hours at least.

[0111] Furthermore, the aromatherapy device 100 further includes a negative ion generating component 80. The negative ion generating component 80 is arranged in the accommodating cavity, and the output end of the negative ion generating component 80 is arranged at the air outlet, and the negative ion generating component 80 is electrically connected to the circuit board 50.

[0112] Specifically, by setting the negative ion generating component 80, negative ions can be generated, and by arranging the output end of the negative ion generating component 80 at the air outlet, when the fan component 20 is working, along with the output of the aromatherapy gas, 100 million-level negative ions can also be output, enabling the air in the environment where the user is located to be clean and fragrant at all times, which helps to further improve the use effect of the aromatherapy device 100.

[0113] It should be understood that as Figure 3 and Figure 5 shown, the negative ion generating component 80 includes a main body 81 and an output pipe 82. Among them, two of the reinforcing ribs 101 on the first housing 11 are arranged at intervals for mounting the main body 81 on the first housing 11. In this embodiment, the main body 81 and the above-mentioned battery 71 are arranged at intervals and on opposite sides of the ventilation cavity. The input end of the output pipe 82 is arranged on the main body 81, and the output end of the output pipe 82 is arranged at the air outlet of the ventilation cavity. At the same time, the negative ion generating component 80 is electrically connected to the circuit board 50 and is opened and closed through the control button 14 on the circuit board 50.

[0114] It should be noted that the output pipe 82 is a flexible pipe. Combining Figure 5 、 Figure 7 and Figure 11 it can be seen that the top of the second housing 12 is provided with a first output hole, and the above-mentioned second ventilation opening 122 is arranged around and at intervals with the first output hole as the center. At the same time, the aromatherapy sheet 30 is provided with a second output hole, the mounting member 40 is provided with a third output hole, and the arrangement modes of the second output hole and the third output hole are the same as that of the first output hole, so as to ensure that the output end of the output pipe 82 can pass through the second output hole and be fixed or pass through the third output hole, so as to ensure that the negative ions output by the negative ion generating component 80 can be output along the extension direction of the airflow towards the ventilation cavity.

[0115] Furthermore, the aromatherapy device 100 further includes a playing component 90. The playing component 90 is arranged in the accommodating cavity, and the playing component 90 is electrically connected to the circuit board 50.

[0116] Specifically, by setting the playing component 90, the functions of the aromatherapy device 100 can be enriched, thereby improving the use effect of the aromatherapy device 100. Such asFigure 2 , Figure 3 and Figure 6 As shown in Figure 2 , Figure 3 , and Figure 6 , the playing component 90 includes two speakers. Correspondingly, two sound holes 114 are provided on the second housing 12, and the two sound holes 114 are spaced apart on opposite sides of the ventilation cavity. Preferably, the two sound holes 114 are provided between the battery 71 and the main body 81, which helps to further improve the utilization efficiency of the accommodation cavity.

[0117] Furthermore, along the extension direction of the first air duct 111, a plurality of support columns are provided on the outer side surface of the first housing 11, and the plurality of support columns are spaced apart along the circumferential direction of the first air duct 111;

[0118] and / or, a cylindrical structure is formed by connecting the cover 13 and the first housing 11, and a supporting surface 103 is provided on one side surface of the cylindrical structure.

[0119] Specifically, by providing the support columns and the supporting surface 103, two placement methods of the aromatherapy device 100, namely horizontal placement and vertical placement, can be realized, which helps to improve the convenience of use of the aromatherapy device 100. Using a plurality of support columns for support helps to ensure that the bottom of the first housing 11 is in a ventilated state, so as to ensure that the air flow can be sucked and output by the fan assembly 20, and at the same time, it also helps to ensure the stability of the placement of the aromatherapy device 100. Among them, the support columns can be set as detachable connections to reduce the manufacturing difficulty of the first housing 11. The supporting surface 103 is formed on the housing 10, which helps to improve the strength of the housing 10.

[0120] It should be understood that the support columns can be set as hemispherical structures and are fixed on the first housing 11 by an adhesive. The support columns are not shown in the figure. At this time, the number of support columns is three, and the three support columns are spaced apart along the circumferential direction of the first air duct 111 to ensure the support of the first housing 11, and at the same time, it helps to ensure the communication between the external air and the first ventilation opening 112. Of course, the shape and number of the support columns can also be set as multiple, as long as it can ensure that the first ventilation opening 112 can communicate with the external environment when the aromatherapy device 100 is horizontally placed.

[0121] As Figure 2 shown, supporting surfaces 103 are provided on both the first housing 11 and the cover 13. When the first housing 11 and the cover 13 are in contact, the supporting surface 103 on the first housing 11 and the supporting surface 103 on the cover 13 cooperate to form a supporting surface for supporting the vertical placement of the aromatherapy device 100. Preferably, the above-mentioned avoidance groove 104 is opened on the supporting surface 103 for accommodating the charging plug 72 and cooperating with the charging plug 72 to support the aromatherapy device 100. In addition, the setting of the supporting surface 103 also helps to ensure the aesthetics of the aromatherapy device 100.

[0122] It should be noted that the support columns can be made of rubber or plastic and are supported by the cooperation of multiple support columns, which helps to further improve the stability and air permeability of the aromatherapy device when it is placed horizontally.

[0123] In addition, it should be noted that the control switch 51 of the above circuit board 50 can be set to one, or can be set to two or three. Among them, when the control switch 51 is three, the following controls can be achieved. Long press the first switch for 2 seconds to turn on or switch the mode. Among them, the mode switching includes the opening and closing of the fan component, the negative ion generating component and the lighting component, as well as the flashing state of the light (such as constant on or flashing, etc.). Short press the first switch once to lock the light effect color or switch the light effect, and the light effect color includes at least 7 colors: red, green, blue, yellow, purple, white, and cyan.
