Because it creates a pleasant atmosphere, aromatherapy is widely used in various settings such as homes, hotels, and vehicles.

[0003] Existing aroma diffusers typically use buttons on their outer surface to control the start / stop and mode. However, the protruding buttons can damage the integrity of the diffuser's surface and affect its aesthetics. Utility Model Content

[0004] In view of this, the present invention provides an aromatherapy device that at least solves the problem that existing aromatherapy devices require buttons, which damages the appearance of the device.

[0005] This application provides an aromatherapy device, including a base, a top cover, an atomizing component, and a switching circuit. The top cover is movably fitted with the base. The atomizing component is located inside the base. The base has a first mist outlet channel that connects to the outside and the outlet of the atomizing component. The atomizing component is electrically connected to the switching circuit. The top cover is located at one end of the base and fits with the base to form a cavity. The switching circuit is located inside the cavity. Movement of the top cover relative to the base can trigger a change in the operating state of the switching circuit, thereby controlling at least the start and stop of the atomizing component.

[0006] In some embodiments, the upper cover is rotatably coupled to the base, the switching circuit includes a first circuit board and a rotation sensor, the first circuit board is fixed in the cavity, the rotation sensor is disposed on the side of the first circuit board near the upper cover, and the rotation sensor includes a connecting shaft connected to the upper cover.

[0007] In some embodiments, the upper cover and the base are raised and lowered in coordination. The switch circuit further includes a push switch, which is electrically connected to the first circuit board. When the upper cover is raised and lowered relative to the base, the upper cover can move away from the push switch or contact the push switch.

[0008] In some embodiments, the first circuit board is spaced apart from the top cover, and an elastic element is provided between the first circuit board and the top cover, the elastic element being able to drive the top cover away from the first circuit board.

[0009] In some embodiments, the elastic element is a spring, which is sleeved on the outside of the rotation sensor.

[0010] In some embodiments, one of the top cover and the base has a protrusion and the other has a corresponding groove for the protrusion to be inserted into. The top cover is movably engaged with the base through the protrusion and the groove.

[0011] In some embodiments, the groove is provided to form an annular groove along the circumference of the upper cover, and the upper cover is rotatably engaged with the base.

[0012] In some embodiments, the upper cover and the base are raised and lowered in a coordinated manner, and the size of the groove is larger than the size of the protrusion along the direction in which the upper cover is raised and lowered relative to the base.

[0013] In some embodiments, the top cover includes a rotating cover and a rotating component connected to the rotating cover. The rotating component is movably engaged with the base.

[0016] By allowing the top cover to move in conjunction with the base, and by triggering a change in the operating state of the switching circuit when the top cover moves relative to the base, such as controlling the atomizing component, there is no need to additionally set buttons on the outer surface of the base or top cover for controlling the atomizing component. This prevents buttons from affecting the integrity of the aromatherapy device's appearance and thus its aesthetics. On the other hand, by acting on any position of the top cover, the operating parameters of the aromatherapy device can be changed without the user needing to find the specific location of the buttons on the top cover or base, making it convenient for the user to operate.

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0027] It should be noted that all directional indicators (such as up, down, left, right, front, back, inside, outside, top, bottom, etc.) in the embodiments of this utility model are only used to explain the relative positional relationship between the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0028] It should also be noted that when a component is referred to as "fixed to" or "set on" another component, the component may be directly on the other component or there may be an intervening component present. When a component is referred to as "connected to" another component, it may be directly connected to the other component or there may be an intervening component present.

[0029] Please see Figures 1 to 8 An embodiment of this utility model provides an aromatherapy device 10, including a base 12, a top cover 14, an atomizing component 16, and a switching circuit 18. The base 12 is used to place on a desktop or car dashboard, etc., and the top cover 14 is movably fitted with the base 12. The atomizing component 16 is located inside the base 12, and the base 12 has a first mist outlet channel 19, which connects the outside to the outlet of the atomizing component 16. Here, the outlet refers to the main opening through which the smoke generated by the atomizing component 16 flows out of the outside of the atomizing component 16. The atomizing component 16 is used to atomize the essential oil inside it into smoke, and the smoke is discharged to the outside of the aromatherapy device 10 through the first mist outlet channel 19 to purify the air. The switching circuit 18 is electrically connected to the atomizing component 16 for controlling the atomizing component 16.

[0030] The upper cover 14 is movably fitted with the base 12, and the upper cover 14 is located at one end of the base 12 and forms a cavity 21 with the base 12. The switch circuit 18 is located inside the cavity 21. When the upper cover 14 moves relative to the base 12, it can trigger the switch circuit 18 to change its working state, thereby controlling at least the start and stop of the atomizing component 16. The switch circuit 18 is used to convert the mechanical movement of the upper cover 14 into an electrical signal, and controls the start and stop of the atomizing component 16 according to the electrical signal. The user can control the atomizing component 16 by moving the upper cover 14 relative to the base 12. The upper cover 14 and the switch circuit 18 cooperate to form a switch for controlling the atomizing component 16. Therefore, it is not necessary to set buttons on the outer surface of the base 12 or the upper cover 14 to control the start and stop of the atomizing component 16, preventing buttons from affecting the integrity of the appearance of the aromatherapy device 10 and affecting its aesthetics. On the other hand, by acting on any position of the upper cover 14, the working parameters of the aromatherapy device can be changed, without the user needing to find the specific location of the buttons on the upper cover 14 or the base 12, making it convenient for the user.

[0031] It should be noted that the movement of the top cover 14 relative to the base 12 is not limited to controlling the start and stop of the atomizing component 16. For example, when the atomizing component 16 has multiple different modes or different power, the movement of the top cover 14 can also switch between different modes or adjust the power. Moreover, when the aromatherapy device 10 also has a light function, the start and stop of the light and its color can also be controlled by the cooperation of the top cover 14 and the switch circuit 18.

[0032] In one embodiment, the upper cover 14 and the base 12 are movably engaged, including a rotational engagement and a lifting engagement. That is, the upper cover 14 and the base 12 form both a rotational engagement and a lifting engagement, so that the upper cover 14 can both rotate relative to the base 12 and move up and down relative to the base 12. When the upper cover 14 rotates or moves up and down relative to the base 12, it can trigger the switch circuit 18 to change its working state, so that when the user presses or rotates the upper cover 14, a control effect is formed, which is convenient for the user.

[0033] In other embodiments, the upper cover 14 may also be rotatably coupled or vertically coupled with the base 12.

[0034] It should be noted that the switch circuit 18 may include a single switch that can be triggered both when the top cover 14 rotates and when the top cover 14 is raised or lowered. Alternatively, the switch circuit 18 may include two switches, one of which is triggered when the top cover 14 rotates and the other of which is triggered when the top cover 14 is raised or lowered.

[0035] In an optional example, the switch circuit 18 includes a first circuit board 22 and a rotation sensor 24. The first circuit board 22 is fixed inside the cavity 21, and the rotation sensor 24 is located on the side of the first circuit board 22 near the upper cover 14. The rotation sensor 24 includes a connecting shaft 25 connected to the upper cover 14, thereby maintaining the connection between the switch circuit 18 and the upper cover 14. When the user rotates the upper cover 14, the upper cover 14 drives the switch circuit 18 to rotate together via the connecting shaft 25, thereby triggering the rotation sensor 24 when the upper cover 14 rotates. The rotation sensor 24, for example, is an encoder, which can collect rotational displacement information or vertical displacement information and convert the displacement information into a digital signal output.

[0036] The switch circuit 18 also includes a push switch (not shown). The push switch is electrically connected to the first circuit board 22. When the user presses the top cover 14 and then releases the top cover 14, the top cover 14 can contact the push switch and then move away from the push switch, so that the top cover 114 can move up and down on the base 12, so that the top cover 14 moves away from the push switch or releases the push switch, thereby triggering the push switch when the top cover 14 moves up and down.

[0037] Optionally, the push switch may be a pressure or distance sensor, and the rotation sensor may be an encoder. In one embodiment, the switch circuit 18 may include only one switch, such as an encoder. The encoder can collect rotational displacement information as well as lifting displacement information, so as to enable the top cover 14 to be rotated and pressed, thereby changing the working state of the aromatherapy device.

[0038] The first circuit board 22 is provided with LED beads 26. At least the portion of the upper cover 14 corresponding to the LED beads 26 is a light-transmitting area. The light generated by the LED beads 26 can pass through the light-transmitting area, thus giving the aromatherapy device 10 a lighting effect and enhancing its aesthetics during use. The light-transmitting area is, for example, made of a transparent material. Optionally, there may be multiple LED beads 26, which are arranged at intervals along the circumference of the first circuit board 22.

[0039] In one optional example, a push-button switch controls the atomizing component 16 to turn on and off. When the atomizing component 16 is on, it atomizes essential oils into smoke and discharges it. When the atomizing component 16 is off, it stops producing smoke. Therefore, the user can control the atomizing component 16 to start and stop by pressing the top cover 14. A rotation sensor is used to control the aromatherapy device 10 to switch between different modes. The aromatherapy device 10 has multiple different working modes. In different working modes, the light emitted by the LED beads 26 is different in color. The user can adjust the working mode of the aromatherapy device 10 by rotating the top cover 14 to adjust the light color.

[0040] The upper cover 14 is provided with a socket 28. The connecting shaft 25 is inserted into the socket 28 and is circumferentially fixed to the upper cover 14, so that when the upper cover 14 rotates, it can drive the switching circuit 18 to rotate together through the connecting shaft 25. At the same time, the insertion of the connecting shaft 25 into the socket 28 does not affect the raising and lowering of the upper cover 14. That is, the connecting shaft 25 and the upper cover 14 are relatively fixed in the circumferential direction, but are axially movable, so that the upper cover 14 can both rotate and raise and lower. For example, the end of the connecting shaft 25 away from the first circuit board 22 is located in the socket 28, and its end includes a columnar structure with a polygonal cross section or an irregular cross section columnar structure. Understandably, the end is a columnar structure with a non-circular cross section. The shape of the socket 28 matches the shape of its end to keep the connecting shaft 25 circumferentially fixed to the socket 28, ensuring that the rotation of the upper cover 14 can drive the rotation of the connecting shaft 25 and avoid slippage.

[0041] The outer side of the connecting shaft 25 and the inner wall of the insertion hole 28 are respectively provided with mutually cooperating limiting planes 30. After the connecting shaft 25 is inserted into the insertion hole 28, the limiting plane 30 on the connecting shaft 25 fits together with the limiting plane 30 on the inner wall of the insertion hole 28, preventing the connecting shaft 25 from rotating relative to the upper cover 14, forming a circumferential fixing effect, while not affecting the lifting and lowering of the upper cover 14.

[0042] The first circuit board 22 and the upper cover 14 are spaced apart. An elastic element 32, such as a spring, is provided between the first circuit board 22 and the upper cover 14. When the user presses the upper cover 14 to move it downwards, the upper cover 14 gradually moves closer to the first circuit board 22. The upper cover 14 compresses the elastic element 32 and causes the elastic element 32 to deform, thereby generating an elastic restoring force. When the pressure on the upper cover 14 is removed, the elastic element 32 can drive the upper cover 14 away from the first circuit board 22. Under the action of the elastic element 32, the upper cover 14 moves upwards to its original position, forming an automatic reset effect, which is convenient for the user to use next time and also improves the pressing feel. In an optional example, the elastic element 32 is a spring, which is sleeved on the outside of the rotation sensor 24, and its two ends are respectively connected to the first circuit board 22 and the upper cover 14. The spring is sleeved on the rotation sensor 24, so that when the upper cover 14 presses the elastic member 32, the rotation sensor 24 plays a guiding role. The elastic member 32 deforms along the height direction of the rotation sensor 24, and the elastic member 32 is not easy to deviate, so that the movement path of the upper cover 14 is not easy to deviate in the height direction of the rotation sensor 24.

[0043] A gasket 33 is provided between the elastic element 32 and the upper cover 14. The gasket 33 can reduce the wear of the elastic element 32 on the upper cover 14 during the movement of the upper cover 14 relative to the base 12.

[0044] In one embodiment, the top of the base 12 is open, and the top cover 14 is movably mounted on the top of the base 12. The top cover 14 is partially located inside the base 12 and movably engages with the base 12, and partially protrudes from the outside of the base 12 to allow the user to operate it.

[0045] The top cover 14 includes a rotating cover 36 and a rotating member 38 that is fitted and fixed to the rotating cover 36. The rotating member 38 is located below the rotating cover 36, and part of the rotating member 38 is inserted into the base 12 and movably engages with the base 12. One end of the rotating member 38 is movably inserted into the base 12 and engages with the base 12 to form a cavity 21. The switch circuit 18 is located on the side of the rotating member 38 away from the rotating cover 36, and the LED 26 is located on the side of the first circuit board 22 near the rotating member 38. At least the portions of the rotating member 38 and the rotating cover 36 corresponding to the LED 26 are transparent areas. In an optional example, both the rotating member 38 and the rotating cover 36 are light-transmitting components, allowing the light generated by the LED 26 to be observed by the user through the rotating member 38 and the rotating cover 36. Optionally, the rotating cover 36 is a crystal cover, as crystal has a light-transmitting effect, allowing the light generated by the LED 26 to pass through the rotating cover 36.

[0046] The rotating cover 36 has a dielectric layer on the side near the rotating component 38. The dielectric layer includes a light-transmitting area and a non-light-transmitting area. The light-transmitting area is, for example, a through hole, and the non-light-transmitting area is an electroplated layer. The light-transmitting area is ring-shaped and corresponds to the position of the LED bead 26. After the light generated by the LED bead 26 passes through the rotating component 38 and reaches the rotating cover 36, the light diffuses outward from the light-transmitting area to form a ring-shaped lighting effect to enhance the aesthetics.

[0047] In one embodiment, the upper cover 14 and the base 12 each have a protrusion 40 and a corresponding groove 42 for the protrusion 40 to be inserted. The upper cover 14 and the base 12 are movably engaged through the engagement of the protrusion 40 and the groove 42, allowing the upper cover 14 to move relative to the base 12, thereby triggering the switching circuit 18. The protrusion 40 and the groove 42 have a simple structure, and the engagement of the protrusion 40 and the groove 42 to achieve the movable engagement of the upper cover 14 and the base 12 helps to reduce manufacturing and assembly difficulties.

[0048] In this embodiment, the upper cover 14 is partially inserted into the interior of the base 12, the protrusion 40 is located on the outer side of the bottom of the upper cover 14, and the groove 42 is located on the inner side of the base 12.

[0049] The upper cover 14 and the base 12 are rotatably engaged and also have a lifting engagement. A groove 42 is formed around the circumference of the upper cover 14 to create an annular groove. The protrusion 40 is inserted into the annular groove and can move within it along its extension direction, thus enabling the upper cover 14 and the base 12 to rotate. Along the direction of lifting and lowering of the upper cover 14 relative to the base 12, the size of the groove 42 is larger than the size of the protrusion 40, leaving space for the protrusion 40 to move up and down, thereby achieving the lifting engagement between the upper cover 14 and the base 12.

[0050] In an alternative example, the groove 42 is a closed annulus, and there are multiple protrusions 40. The multiple protrusions 40 are arranged at intervals along the circumference of the upper cover 14, and each protrusion 40 is inserted into the groove 42 to improve the stability of the connection between the upper cover 14 and the base 12.

[0051] In one embodiment, the base 12 includes a main shell 44 and a mist-emitting assembly 46 installed inside the main shell 44. A second mist-emitting channel 48 is formed within the mist-emitting assembly 46. One end of the second mist-emitting channel 48 communicates with a first mist-emitting channel 19, and the other end of the second mist-emitting channel 48 forms a mist outlet 20 communicating with the outside. The mist outlet 20 is provided on the base 12 and surrounds the outer circumference of the upper cover 14, allowing smoke to be emitted circumferentially along the upper cover 14, forming a ring-shaped mist effect. The upper cover 14 and the mist-emitting assembly 46 cooperate to form a cavity 21. The cavity 21 is spaced apart from the second mist-emitting channel 48, and the switch circuit 18 is located inside the cavity 21, thereby separating the switch circuit 18 from the second mist-emitting channel 48 through the mist-emitting assembly 46. The atomizing component 16 atomizes and generates smoke, which enters the second mist outlet channel 48 through the first mist outlet channel 19 and is finally discharged from the mist outlet 20. The second mist outlet channel 48 is located inside the mist outlet component 46, while the switching circuit 18 is located outside the mist outlet component 46, thus isolating the switching circuit 18 from the second mist outlet channel 48. This prevents the smoke from contacting the switching circuit 18 and causing corrosion when it flows within the second mist outlet channel 48. Furthermore, the mist outlet 20 surrounds the outer periphery of the upper cover 14, which helps to increase the mist outlet area and avoid the mist outlet position being too concentrated. When the smoke is discharged from the mist outlet 20, the light generated by the LED bead 26 can illuminate the smoke, combining the smoke and light to further enhance the aesthetics of the aromatherapy device 10 during use.

[0052] A guide member 50 is provided on the outer side of the upper cover 14 at the position corresponding to the mist outlet 20. The guide member 50 is annular and surrounds the outer periphery of the upper cover 14. The guide member 50 extends outward in a direction away from the mist outlet 20, thereby forming a guide surface on the outer surface of the guide member 50. The guide surface extends outward at an upward angle from the mist outlet 20. When the smoke moves to the mist outlet 20, it can be discharged outward under the guidance of the guide surface on the guide member 50, so that the smoke is discharged from the mist outlet 20 more smoothly.

[0053] One end of the first mist outlet channel 19 is connected to the atomizing component 16, and the other end forms an outlet 52 connected to the second mist outlet channel 48. The second mist outlet channel 48 is equipped with multiple diversion baffles 54, which are arranged at intervals along the circumference of the outlet 52 and extend away from the outlet 52. A flow channel for smoke flow is formed between two adjacent diversion baffles 54. The diversion baffles 54 can divert the smoke; when smoke enters the second mist outlet channel 48 from the outlet 52, it flows into each flow channel under the action of the diversion baffles 54, making the smoke more evenly distributed when discharged from the mist outlet 20, preventing the mist from being too concentrated and affecting the aesthetics of the mist and the smoke discharge.

[0054] In an alternative example, multiple diversion baffles 54 are evenly spaced along the circumferential intervals of the outlet 52, thereby making the mist output more uniform.

[0055] A protruding post 73 is provided on the outer side of the misting component 46. The protruding post 73 is located between the misting component 46 and the atomizing component 16. The first misting channel 19 passes through the protruding post 73, thereby connecting the misting component 46 and the atomizing component 16.

[0056] The misting assembly 46 includes a first separator 56 and a second separator 58 spaced apart, with the gap between the first separator 56 and the second separator 58 forming a second misting channel 48. A diverter baffle 54 is located between the first separator 56 and the second separator 58, and is connected to both the first separator 56 and the second separator 58, thereby supporting the first separator 56 and separating the first separator 56 and the second separator 58 to form the second misting channel 48. The first separator 56 is located near the upper cover 14, and the second separator 58 is located near the atomizing assembly 16. That is, the atomizing assembly 16 is located on the side of the second separator 58 away from the first separator 56. The upper cover 14 is movably fitted with the first separator 56 to form a cavity 21. The first misting channel 19 passes through the second separator 58, and the outlet 52 is located on the second separator 58, with the first separator 56 located above the outlet 52. After the smoke enters the second mist outlet channel 48, it moves between the first separator 56 and the second separator 58. The first separator 56 and the second separator 58 can separate the smoke from the electrical components located outside the first separator 56 and the second separator 58 to prevent the smoke from corroding the electrical components when it flows in the second mist outlet channel 48.

[0057] In one embodiment, the first partition 56 and the second partition 58 are similar in shape. The first partition 56 includes a first base plate 60 and a first surrounding wall 62 surrounding the outer periphery of the first base plate 60. The second partition 58 includes a second base plate 64 and a second surrounding wall 66 surrounding the outer periphery of the second base plate 64. The first base plate 60 and the second base plate 64 are disposed opposite each other at intervals, and the second surrounding wall 66 is spaced around the outer periphery of the first surrounding wall 62 at intervals. The first mist outlet channel 19 passes through the second base plate 64, and the outlet 52 is disposed on the second base plate 64, with the first base plate 60 located above the outlet 52. The gap between the first base plate 60 and the second base plate 64, and the gap between the first enclosure wall 62 and the second enclosure wall 66 together form the second mist outlet channel 48. The mist outlet 20 is located between the end of the first enclosure wall 62 away from the first base plate 60 and the end of the second enclosure wall 66 away from the second base plate 64. The diversion baffle 54 is located between the first base plate 60 and the second base plate 64. The upper cover 14 is movably fitted with the first enclosure wall 62. The switch circuit 18 is located inside the first partition 56.

[0058] The first base plate 60 and the first enclosure 62 cooperate to form a first storage space, and the second base plate 64 and the second enclosure 66 cooperate to form a second storage space. The circumferential dimension of the first partition 56 is smaller than that of the second storage space, so that the first partition 56 is stored in the second storage space. The first partition 56 and the second partition 58 are separated from each other by the diversion baffle 54. The upper cover 14 is located in the first storage space and cooperates with the first partition 56 to form a cavity 21. The first partition 56 can separate the smoke from the switch circuit 18 to prevent the smoke from entering the first storage space and corroding the switch circuit 18 in the first storage space. Similarly, the second base plate 64 and the second enclosure 66 are set to cooperate to form a second storage space to prevent the second circuit board 86 of the atomizing component 16 or the fan 94 from being affected by the smoke. Meanwhile, the second storage space formed by the second base plate 64 and the second enclosure 66 also has the function of accommodating residual liquid. During the flow of smoke in the second mist outlet channel 48, some smoke will adhere to the surface of the first separator 56 and the second separator 58 to form liquid. The liquid accumulates in the second storage space under the action of gravity to prevent residual liquid from flowing out.

[0059] The second base plate 64 has a protruding post 73 on the side away from the first base plate 60. The protruding post 73 extends from the second base plate 64 to the atomizing component 16. The first mist outlet channel 19 passes through the protruding post 73 and the second base plate 64, so that the two ends of the first mist outlet channel 19 are connected to the atomizing component 16 and the second mist outlet channel 48, respectively.

[0060] The first base plate 60 and the second base plate 64 are respectively provided with wire-passing holes 68, and the wire-passing holes 68 on the first base plate 60 and the second base plate 64 are correspondingly arranged. The wire-passing holes 68 are used for wires to pass through, so that the switching circuit 18 can be electrically connected to the atomizing component 16 through the wires, thereby controlling the start and stop of the atomizing component 16.

[0061] The first base plate 60 and the second base plate 64 are respectively provided with annular protrusions 70 on their opposite sides. The protrusions 70 surround the outer periphery of the corresponding wire passage hole 68. The two protrusions 70 extend towards each other and fit together. The components connecting the atomizing component 16 and the switching circuit 18 pass through the inner side of the two protrusions 70. The protrusions 70 can separate the smoke from the wire and prevent the smoke in the mist outlet channel 48 from corroding the wire. At the same time, the protrusions 70 on the second base plate 64 can also prevent the residual liquid in the second separator 58 from flowing out through the wire passage hole 68.

[0062] One of the first base plate 60 and the second base plate 64 is fixedly connected to the diversion baffle 54, and the other is provided with a limiting groove 72 for the diversion baffle 54 to be inserted. After the diversion baffle 54 is inserted into the limiting groove 72, it can limit the first separator 56 and the second separator 58, so that the first separator 56 and the second separator 58 remain relatively fixed in the circumferential direction.

[0063] In an optional example, the diversion baffle 54 is fixed on the first base plate 60, and the limiting groove 72 is correspondingly provided on the second base plate 64. There are multiple diversion baffles 54 and limiting grooves 72, and they correspond one-to-one. Each diversion baffle 54 is inserted into a corresponding limiting groove 72, which further enhances the support and limiting effect of the diversion baffle 54 on the first separator 56.

[0064] The outlet 52 is located in the middle of the second base plate 64. The second base plate 64 is inclined from the periphery of the outlet 52 in a direction away from the top cover 14. The first base plate 60 is inclined from the middle of the first base plate 60, which is directly opposite the outlet, in a direction away from the top cover 14. That is, both the first base plate 60 and the second base plate 64 form a shape that is high in the middle and low around the edges. This makes the part of the second mist outlet channel 48 located between the first base plate 60 and the second base plate 64 also form a shape that is high in the middle and low around the edges. The smoke in the first mist outlet channel 19 enters the second mist outlet channel 48 from the middle of the second base plate 64 and then flows towards the periphery of the second base plate 64, forming a shape that is high in the middle and low around the edges. This makes the smoke flow more smoothly between the first base plate 60 and the second base plate 64. At the same time, it also allows the residual liquid in the second partition 58 to flow along the second bottom plate 64 to the connection between the second bottom plate 64 and the second enclosure 66, which is directly opposite the mist outlet 20, so as to accelerate the evaporation of the liquid at that location and reduce liquid residue.

[0065] The first base plate 60 forms an inwardly concave arc surface at the part corresponding to the outlet 52. After the smoke is discharged from the outlet 52, it blows towards this arc surface, and under the action of this arc surface, it spreads more evenly in all directions.

[0066] In one embodiment, the atomizing component 16 includes a fragrance diffuser 74, which is electrically connected to the switching circuit 18. The first mist outlet channel 19 is connected to the outlet of the fragrance diffuser 74. The fragrance diffuser 74 atomizes the essential oil inside it by heating to form smoke, which flows into the first mist outlet channel 19 and is finally discharged to the outside from the mist outlet 20.

[0067] The fragrance diffuser 74 includes an essential oil box and a heating element and absorbent cotton located inside the essential oil box. The absorbent cotton is used to absorb and lock in the essential oil to prevent leakage. The heating element includes a heating wire, a heating plate, and a cotton swab. The heating wire is connected to the heating plate, and the cotton swab is in contact with the heating plate. The cotton swab can absorb the essential oil on the absorbent cotton. The heat generated by the heating wire is conducted to the cotton swab through the heating plate, thereby atomizing the essential oil on the cotton swab to form smoke.

[0068] The base 12 includes a bracket 75 with a mounting groove 76. The diffuser 74 is detachably installed into the mounting groove 76 so that when the essential oil in the diffuser 74 is used up or almost used up, the user can remove the diffuser 74 to easily add essential oil. It can also be replaced when the diffuser 74 is damaged.

[0069] One end of the mounting groove 76 forms a slot 77 for the fragrance diffuser 74 to enter or exit. Recesses on opposite sides of the fragrance diffuser 74 form handle positions 78, which are positioned near the slot 77. When installing or removing the fragrance diffuser 74 from the mounting groove 76, the user can place two fingers in the two handle positions 78 respectively to grip the fragrance diffuser 74, facilitating its installation and removal.

[0070] The fragrance diffuser 74 and the bracket 75 are respectively provided with magnetic components 80. After the fragrance diffuser 74 is installed into the mounting groove 76, the magnetic component 80 of the fragrance diffuser 74 and the magnetic component 80 on the bracket 75 are magnetically attracted to each other, which enhances the stability of the fragrance diffuser 74 when it is installed in the mounting groove 76.

[0071] The main body shell 44 of the base 12 includes an inner shell 82 and an outer shell 84 located outside the inner shell 82. The bracket 75 is disposed in the inner shell 82, or the bracket 75 is part of the inner shell 82. When the fragrance diffuser 74 is installed in the mounting groove 76, the outer shell 84 can prevent the fragrance diffuser 74 from being exposed, thus preventing the fragrance diffuser 74 from being exposed and affecting the integrity of the appearance of the aromatherapy device 10, and at the same time, it can also protect the fragrance diffuser 74.

[0072] The outer casing 84 includes a detachably connected first casing and a second casing, with the second casing located below the first casing and the inner casing 82 located inside the second casing. During the assembly and disassembly of the fragrance diffuser 74, the first casing and the second casing can be separated first. The second casing is smaller in height than the outer casing 84, making it convenient for the user to assemble and disassemble the inner casing 82, allowing for easy removal of the inner casing 82 to replace the fragrance diffuser 74 or add essential oil to the fragrance diffuser 74.

[0073] The atomizing assembly 16 also includes a second circuit board 86 mounted on the bracket 75. The second circuit board 86 has conductive posts 88 extending toward the mounting groove 76. The fragrance diffuser 74 has a spring pin 90, one end of which protrudes from the outside of the fragrance diffuser 74. When the fragrance diffuser is installed into the mounting groove 76, the spring pin 90 is electrically connected to the conductive posts 88, thereby achieving an electrical connection between the fragrance diffuser 74 and the second circuit board 86. The switching circuit 18 achieves an electrical connection with the atomizing assembly 16 by connecting to the second circuit board 86. The spring pin 90 has a certain elasticity and can move downward a certain distance when pressure is applied. After the fragrance diffuser 74 is installed into the mounting groove 76, the conductive posts 88 and spring pin 90 are positioned opposite each other and press against the spring pin 90. Under the action of elasticity, the spring pin 90 is tightly pressed against the conductive posts 88, enhancing the stability of the electrical connection between the second circuit board 86 and the fragrance diffuser 74.

[0074] The mounting groove 76 has a clearance surface 92 on its groove wall near the spring pin 90. The clearance surface 92 extends at an angle away from the fragrance diffuser 74 to the groove opening 77, increasing the area of ​​the mounting groove 76 at the groove opening 77. This allows the spring pin 90 to be avoided during the installation of the fragrance diffuser 74 into the mounting groove 76. The angled setting of the clearance surface 92 also causes the groove opening 77 to gradually decrease in size towards the conductive post 88. The clearance surface 92 provides a guide for the movement of the fragrance diffuser 74, gradually squeezing the spring pin 90 along the inclined surface, which facilitates the installation of the fragrance diffuser 74.

[0075] In one embodiment, the base 12 is equipped with a fan 94 and an air guide shroud 96. The air guide shroud 96 is equipped with an air guide channel 97. The air outlet of the fan 94 is connected to the inlet of the atomizing component 16 through the air guide channel 97. The fan 94 can drive the airflow through the air guide channel 97 into the atomizing component 16, and drive the smoke in the atomizing component 16 to move towards the mist outlet 20, thereby improving the mist output efficiency.

[0076] The base 12 has a through hole that communicates with the air inlet of the fan 94. This through hole is located at the bottom of the base 12 so that outside air can enter the interior of the base 12 through the through hole. The bottom of the base 12 is also provided with a silicone pad 95 to increase the friction between the base 12 and the supporting surface and to achieve an anti-slip effect.

[0077] The inner diameter of the air guide channel 97 near the atomizing component 16 is smaller than the inner diameter near the fan 94. The reduced inner diameter of the air guide channel 97 can accelerate the airflow speed and further improve the mist output efficiency.

[0078] The air guide shroud 96 is provided with a guide arc surface 98. The guide arc surface 98 extends obliquely from the air guide channel 97 near the air outlet of the fan 94 toward the atomizing component 16 to guide the airflow toward the atomizing component 16, reduce the wind resistance of the airflow during the movement, increase the airflow while reducing noise.

[0079] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
