The lower component 24 includes a base 34, which is connected to the lower port of the wall tube 30. For example, the base 34 and the wall tube 30 are detachably connected by means of buckles. In the illustrated embodiment, the base 34 includes a bottom wall 34a, a side wall 34b, and an inclined wall 34c connected between the bottom wall 34a and the side wall 34b and tilted outward. A plurality of sliding slots 36 are circumferentially provided on the outer surface of the side wall 34b, and a plurality of sliding buckles 38 are correspondingly provided on the inner wall of the wall tube 30. When installed, the sliding buckles 38 are fixed by rotating into the sliding slots 36, which is convenient for users to disassemble and assemble to replace or maintain the atomization component.

Specifically, the upper cover part 42 extends toward the lower cover part 44 to form a first surrounding wall 50, and the lower cover part 44 extends toward the upper cover part 42 to form a second surrounding wall 52. The first surrounding wall 50 is connected to the second surrounding wall 52 and is enclosed together with the upper cover part 42 and the lower cover part 44 to form the air duct 18. In the illustrated embodiment, the air duct 18 is in the shape of a rectangular parallelepiped as a whole and extends laterally along the width direction (a radial direction) of the main body 12.

Specifically, an opening connected to the air duct 18 is opened on the second surrounding wall 52, and a through hole is provided on the wall tube 30 corresponding to the opening. The opening and the through hole together form the mist outlet 16. A kit 58 is also provided in the opening and the through hole to increase the sealing performance and prevent mist from entering the gaps in the components.

[0033] like Figure 3As shown, a mounting position 60 is provided on one side of the mounting frame 28 away from the mist outlet 16, and the air supply device 14 is installed at the mounting position 60. The air supply device 14 is, for example, a fan. The air supply device 14 has an air outlet 62, and the lower cover member 44 is provided with a connecting port 64 corresponding to the air outlet 62. The air outlet 62 is connected to the air duct 18 through the connecting port 64. In the embodiment shown, the air supply device 14 is placed vertically relative to the mist outlet 16, that is, the air outlet direction of the air outlet 62 is perpendicular to the mist outlet direction of the mist outlet 16.

[0034] Furthermore, a blocking portion 66 is provided on the side of the upper component 22 close to the air outlet 62. Specifically, the blocking portion 66 is located on the side of the lower cover component 44 at the connecting port 64 close to the mist outlet 16. The top of the blocking portion 66 is arranged higher than the bottom wall of the air duct 18, which can prevent the condensed liquid in the air duct 18 from flowing back to the air supply device 14, thereby avoiding the condensed liquid from corroding and damaging the air supply device.

[0035] In the embodiment shown, Figure 2 As shown, the atomization port 20 is located between the air outlet 62 and the mist outlet 16 , and the mist outlet direction of the atomization port 20 can be set to be perpendicular to the extension direction of the air duct 18 . The atomization assembly includes a container 68 for placing aromatherapy liquid, a sleeve 70 for placing a liquid transfer component, and an atomization sheet (not shown) for atomizing the aromatherapy liquid. The sleeve 70 is a top open structure. The middle part of the mounting frame 28 protrudes toward the lower cover member 44 to form a connecting portion 72. The container 68 is bottle-shaped, including a bottle body and a bottle mouth connected to each other. The top of the sleeve 70 is connected to the top wall of the connecting portion 72. Preferably, the sleeve 70 and the connecting portion 72 (mounting frame 28) are an integrally formed structure, and a recess is formed between the sleeve 70 and the connecting portion 72. The tube body portion of the sleeve 70 extends into the container 68, and the bottle mouth portion of the container 68 is connected to the inner side wall of the connecting portion 72. The two are detachably connected, for example, by a threaded manner, so that the container 68 can be disassembled and assembled to replenish the aromatherapy liquid, replace and maintain the container 68, etc. The bottom portion of the container 68 is located in the space enclosed by the base 34. The atomizing port 20 is provided at a position corresponding to the sleeve 70 on the lower cover member 44. The outer bottom of the atomizing port 20 is provided with an annular wall, which is connected to the outer periphery of the depression. The space enclosed by the annular wall and the depression together form an accommodating space 74, and the atomizing sheet is arranged in the accommodating space 74. The sleeve 70 is provided with a liquid transmission component, which is a component that can transmit liquid, such as a cotton core. The portion of the sleeve 70 located in the container 68 is provided with a perforation 76. The aromatherapy liquid in the container 68 enters the cotton core through the perforation 76. The top of the cotton core is connected to the atomizing sheet. The atomizing sheet atomizes the aromatherapy liquid in the cotton core into mist. The mist enters the air duct 18 through the atomizing port 20. The wind generated by the air supply device 14 enters the air duct 18 through the air outlet 62 and the connecting port 64. Then the wind flows along the air duct 18 and sends the mist coming out of the atomizing port 20 to the mist outlet 16, and finally sprays out from the mist outlet 16.

[0036] Preferably, the cross-sectional area of ​​the end of the air duct 18 close to the mist outlet 16 is smaller than the cross-sectional area of ​​the end of the air duct 18 away from the mist outlet 16. Such a configuration can facilitate the mist to be ejected from the mist outlet 16 in a strip shape, thereby improving the mist outlet efficiency. Specifically, the portion of the air duct 18 between the atomization port 20 and the mist outlet 16 gradually narrows in the direction toward the mist outlet 16. For example, the wall thickness of the upper cover component 42 and the lower cover component 44 between the atomization port 20 and the mist outlet 16 gradually increases. In the illustrated embodiment, the inner wall surface of the portion of the lower cover component 44 corresponding to the air duct 18 is tilted downward toward the atomization port 20, so that the mist outlet 16 and the condensed liquid in the air duct can flow back to the atomization port 20 and finally flow to the atomization sheet to be recycled again.

[0037] In the illustrated embodiment, please also refer to Figure 1 and Figure 2 As shown, the periphery of the cover 32 is provided with an air inlet 78 connected to the air supply device 14, and the external air enters the air supply device 14 through the air inlet 78.

A battery 88 is also provided on one side of the mounting frame 28. The battery 88 is electrically connected to the circuit board 84 to provide power supply for the atomizing device 10. A decorative element 90 is provided on the top edge of the top cover 80. The decorative element 90 is arranged around the periphery of the control key 86.

[0038] like Figure 2 As shown, a fog lamp 92 is provided on one side of the upper cover component 42 close to the air outlet 62. The fog lamp 92 is electrically connected to the circuit board 84 and protrudes into the air duct 18. The light generated by the fog lamp 92 can pass through the mist outlet 16 to form a lighting effect at the mist outlet 16, and cooperate with the mist sprayed from the mist outlet 16 to form a smoke landscape, thereby improving the ornamental value of the atomization device 10.

[0039] In the embodiment shown, Figure 3As shown, a light-transmitting component 94 is provided on the inclined wall 34c of the base 34, and a light-emitting component 96 is provided on the side of the mounting frame 28 away from the cover 32.

Specifically, an annular support 98 is provided at the bottom of the mounting frame 28, and the annular support 98 is made of a light-transmitting material. A support block 100 is provided on the inner wall of the wall tube 30. The annular support 98 is supported on the support block 100 and is fixedly connected to the mounting frame 28, for example, by screw connection. An annular groove 102 is provided on the outer wall of the annular support 98. The light-emitting component 96 is, for example, a light bar, and the light-emitting component 96 is arranged in the annular groove 102.
