[0023] Before describing the embodiments in detail, it should be understood that the present application is not limited to the detailed structure or component arrangement described below or in the drawings in the present application. The present application may be an embodiment implemented in other ways. Moreover, it should be understood that the words and terms used herein are only used for descriptive purposes and should not be interpreted restrictively. The words "including", "comprising", "having" and the like used herein are meant to include the items listed thereafter, their equivalents and other additional items. In particular, when describing "a certain element", the present application does not limit the number of the element to one, but may also include multiple elements.

[0024] Please also refer to Figures 1 to 4As shown, the present application provides a liquid leakage-proof atomizing device 10 (hereinafter referred to as the atomizing device 10), which can be used in environments such as home, office, and driving. In the present embodiment, the atomizing device 10 is cylindrical as a whole. In other embodiments, the atomizing device 10 can also be designed in other shapes. The atomizing device 10 includes a housing 12, a fan 14 and an atomizing structure arranged in the housing 12. A mist outlet 16 is provided on the side wall of the housing 12, so that the atomizing device 10 can discharge mist laterally, which can effectively solve the problem that the top of the existing atomizing device discharges mist upward, causing the mist to be directly sprayed onto the windshield and affect the driving line of sight. It will not affect the driver's driving of the vehicle and eliminate safety hazards. An airflow channel 18 is formed between the fan 14 and the mist outlet 16, and the atomizing structure is provided with an atomizing port 20 connected to the airflow channel 18. The wind generated by the operation of the fan 14 blows the mist coming out of the atomizing port 20 out of the mist outlet 16 through the airflow channel 18. A leak-proof structure is provided at the mist outlet 16 to prevent the condensed liquid from leaking out of the shell 12. For example, by providing the leak-proof structure, the aromatherapy liquid condensed at the mist outlet 16 will flow back into the air flow channel 18 for recovery or reuse, or by providing the leak-proof structure, the condensed liquid formed at the mist outlet 16 can be directly absorbed to prevent the condensed aromatherapy liquid from leaking out, thereby achieving a leak-proof effect.

[0025] The mist outlet 16 can be designed to be in the shape of dots, strips, circles, squares, rings or special shapes, and the mist can be sprayed in different shapes according to the shape of the mist outlet 16. In this embodiment, the mist outlet 16 is designed to be in the shape of a strip. Compared with the existing top mist outlet, the mist outlet 16 is arranged on the side of the housing 12, which can increase the size of the mist outlet 16, facilitate rapid spraying, increase the spray volume, and enhance the fragrance dispersion effect.

[0026] The anti-leakage structure may be provided at the mist outlet 16, that is, the structure of the mist outlet 16 itself is improved so that the condensate formed at the mist outlet 16 can flow back into the air flow channel 18, thereby achieving an anti-leakage effect; and / or, the anti-leakage structure may also be an absorbent 72 provided inside the mist outlet 16, and the absorbent 72 is used to absorb the condensate formed at the mist outlet 16, thereby achieving an anti-leakage effect. In the illustrated embodiment, the anti-leakage structure includes a portion provided at the mist outlet 16 and the absorbent 72.

[0027] Preferably, if Figure 2As shown, the mist outlet 16 is designed to have a size closer to one end of the air flow channel 18 than the size away from the end of the air flow channel 18. For example, the mist outlet 16 can be designed to be trumpet-shaped, and the size of the mist outlet 16 gradually decreases in the mist outlet direction of the mist outlet 16. The size of the outer port of the mist outlet 16 is smaller than the size of the inner port. The bottom wall of the mist outlet 16 can be set as an inclined surface, and the height of the bottom wall of the mist outlet 16 close to one end of the air flow channel 18 is lower than the height of the bottom wall of the mist outlet 16 away from the end of the air flow channel 18, so that the condensed aromatherapy liquid flows along the inclined bottom wall of the mist outlet into the air flow channel 18, which plays a role in preventing liquid leakage. The timely reflux of the condensed liquid can avoid overflowing to the outer wall of the shell 12, thereby affecting the product service life and user experience.

[0028] In some embodiments, the mist outlet 16 can also be designed with a horizontal top wall and an inclined bottom wall, or the top and bottom walls of the mist outlet 16 can be designed with inclined surfaces with the same or approximately the same inclination direction, both of which can achieve a liquid leakage prevention effect.

[0029] In this embodiment, please also refer to Figure 3 and Figure 4 As shown, the housing 12 includes an outer shell 22 and an inner shell 24 disposed in the outer shell 22, wherein the outer shell 22 includes an outer wall portion 26, the outer wall portion 26 is a structure with upper and lower ends opening, and the inner shell 24 includes an inner wall portion 28 connected to the inner side of the outer wall portion 26, the inner wall portion 28 is a structure with upper and lower ends opening, and the outer wall portion 26 and the inner wall portion 28 are fixedly connected, for example, by screws. The outer wall portion 26 is provided with a first opening 30 near the top side, and the inner wall portion 28 is provided with a second opening 32 corresponding to the first opening 30, and the first opening 30 and the second opening 32 together form the mist outlet 16.

[0030] In the illustrated embodiment, the housing 22 also includes a top cover 34 connected to the top opening of the outer wall portion 26 and a base 36 connected to the bottom opening of the outer wall portion 26.

The base 36 is detachably connected to the bottom end of the outer wall portion 26, for example, the outer wall of the base 36 is threadedly connected to the inner wall of the outer wall portion 26.

[0031] The inner shell 24 includes a base plate 38 connected to the bottom opening of the inner wall portion 28. The top end of the inner wall portion 28 is supported on the bottom of the top cover 34. A fixing frame 40 is provided between the base plate 38 and the inner wall portion 28, that is, the fixing frame 40 is arranged in the space enclosed by the base plate 38 and the inner wall portion 28. The airflow channel 18 and the atomization port 20 are both formed on the fixing frame 40.

[0032] Specifically, the fixing frame 40 is supported and fixed on the base plate 38, for example, the fixing frame 40 is fixed to the base plate 38 or the inner wall portion 28 by screws to ensure the stability of the fixing frame 40. The fixing frame 40 includes a first frame body 42 and a second frame body 44 that form the airflow channel 18, and the first frame body 42 and the second frame body 44 are connected to each other, for example, the airflow channel 18 is formed between the first frame body 42 and the second frame body 44. The first frame body 42 is located between the base plate 38 and the second frame body 44, and the second frame body 44 is provided with a connecting wall 46 extending toward the first frame body 42, and the first frame body 42 is provided with a connecting groove 48 corresponding to the connecting wall 46, and the bottom end of the connecting wall 46 is connected to the connecting groove 48, and the connecting wall 46, the first frame body 42, the second frame body 44 and the inner wall portion 28 are enclosed together to form the airflow channel 18.

[0033] A mounting position 50 is provided on one side of the second frame 44 away from the mist outlet 16, and the fan 14 is installed at the mounting position 50. The second frame 44 is provided with an air outlet 52 corresponding to the fan 14, which connects the fan 14 and the air flow channel 18. Preferably, the air outlet direction of the air outlet 52 is arranged parallel to the mist outlet direction of the mist outlet 16, that is, the fan 14 is installed and placed parallel to the mist outlet 16, and the air outlet 52 is arranged toward the mist outlet 16 and directly faces the air flow channel 18, which can greatly improve the efficiency of the use of air volume and wind force, and reduce wind noise at the same time.

[0034] The middle part of the base plate 38 is convexly provided with a protrusion 54 toward the side of the fixing frame 40, and the first frame 42 is concavely provided with a recessed portion 56 corresponding to the protrusion 54 toward the side of the second frame 44, and the protrusion 54 is connected to the recessed portion 56. The atomization structure includes a first member 58 extending from the recessed portion 56 toward the side of the protrusion 54, a second member 60 extending from the protrusion 54 toward the side away from the first frame 42, a bottle body 62 for containing aroma liquid, an atomizing sheet 64 for atomizing the aroma liquid, and a pipe sleeve 66 for placing a liquid transfer component. Among them, the atomization port 20 is arranged at the bottom of the first component 58, the atomization sheet 64 is arranged between the first component 58 and the second component 60, the second component 60 is convex, and the bottom of the second component 60 is provided with a through hole 68, so that the liquid transfer part in the tube sleeve 66 can transfer the aromatherapy liquid to the atomization sheet 64, the tube sleeve 66 is detachably sleeved on the bottom outer wall of the second component 60, for example, by snapping, sticking, etc., so that the tube sleeve 66 and the liquid transfer part can be removed and replaced as needed, which brings convenience to the user. The liquid transfer part is, for example, a cotton swab, which is arranged in the tube sleeve 66, and the top of the cotton swab passes through the through hole 68 to contact the atomization sheet 64, and the bottom end of the tube sleeve 66 extends into the bottle body 62 and allows the cotton swab to be immersed in the aromatherapy liquid in the bottle body 62. For example, a plurality of perforations are provided at the bottom of the tube sleeve 66, so that the aromatherapy liquid can enter the tube sleeve 66 through the perforations and soak the cotton swab. The bottle body 62 is detachably connected to the inner wall of the protruding portion 54 , for example, the two are threadedly connected, so that the bottle body 62 can be replaced and maintained.

[0035] Preferably, an absorbent 72 for absorbing the refluxed condensate is provided between the atomizing port 20 and the mist outlet 16, and the absorbent 72 is, for example, oil-absorbing cotton. In the illustrated embodiment, a mounting portion 73 for mounting the absorbent 72 is provided on the first frame 42, and the mounting portion 73 is, for example, a groove structure formed between the recessed portion 56 and the inner wall portion 28, and the absorbent 72 is disposed on the mounting portion 73, and the height of the absorbent 72 near the mist outlet 16 is greater than the height of the absorbent 72 near the atomizing port 20. For example, the top end of the absorbent 72 near the mist outlet 16 is flush with the inner edge of the mist outlet 16, and the top end of the absorbent 72 near the atomizing port 20 is flush with the top wall surface of the recessed portion 56, so that the condensate flowing back from the mist outlet 16 can be directly absorbed by the absorbent 72, thereby preventing the condensate from flowing out to the outer wall of the housing 12.

[0036] In the illustrated embodiment, the installation height of the atomizer sheet 64 is lower than the height of the bottle mouth of the bottle body 62. Such a configuration can provide atomization height space to the maximum extent, thereby solving the problem that the distance from the atomizer sheet 64 to the corresponding upper wall is too small, resulting in the mist hitting the upper wall and condensing before it is fully dispersed, causing insufficient atomization.

[0037] A circuit board 76 is provided between the top cover 34 and the second frame 44. A fog lamp 78 is provided on one side of the second frame 44 near the mist outlet 16. The fog lamp 78 is, for example, a SMD LED, which can avoid the problem that the fog lamp extends into the airflow channel 18 and occupies space, obstructs the airflow and affects the mist outlet efficiency, thereby improving the utilization rate of the airflow channel 18, reducing wind noise, and facilitating production and assembly. The light generated by the fog lamp 78 can be transmitted through the mist outlet 16, forming a lighting effect at the mist outlet 16, and cooperates with the mist sprayed from the mist outlet 16 to form a smoke landscape, thereby improving the ornamental value of the atomizing device 10.

[0038] The fan 14, the atomizing sheet 64 and the fog lamp 78 are electrically connected to the circuit board 76, respectively. A control key 80 electrically connected to the circuit board 76 is provided at the top center of the top cover 34.

An air inlet 86 connected to the fan 14 is provided along the circumferential direction at the edge of the top cover 34, so that external air can enter the fan 14 through the air inlet 86.

[0039] In the illustrated embodiment, a support member 88 is further provided at the bottom of the inner shell 24. The support member 88 is an open structure at the upper end and covers the bottom of the inner shell 24. The support member 88 is supported on the base 36 and an annular groove 90 is formed between the support member 88 and the inner shell 24.
