[0036] ​​​To better understand the technical content of this utility model, the following will further introduce and explain this utility model in conjunction with the accompanying drawings and specific embodiments. It should be noted that if there are descriptions such as "first" and "second" in the text, they are used to distinguish different components, etc., and do not represent the order of priority, nor do they limit "first" and "second" to be different types.

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0038] Example

[0039] like Figures 1 to 11 As shown in the figure, the lifting smoke waterfall device 100 shown in this embodiment includes a hollow outer shell 1, a main unit 2 that slides up and down inside the outer shell 1, and a driving device located inside the outer shell for driving the upper end of the main unit 2 to slide upward out of the outer shell 1 or retract back into the outer shell 1. The top of the main unit 2 is provided with a visible cavity 300, that is, during the up and down movement of the main unit 2, the visible cavity 300 slides upward out of the outer shell 1 or retracts back into the outer shell 1, so that after it protrudes out of the outer shell 1, the inside of the cavity 300 can be viewed by a person; a raised fog inlet channel 301 is provided in the middle of the bottom of the cavity 300, and a smoke channel 302 is formed between the top of the fog inlet channel 301 and the top of the cavity 300 for the smoke to flow in all directions, so that the smoke enters from the top of the cavity 300 and flows downward along the smoke channel 302 to form a smoke waterfall landscape. The main unit 2 is provided with an atomizer 9 for generating smoke, and the fog outlet of the atomizer 9 is connected to the fog inlet channel 301.

[0040] In the above, the main unit first uses a drive device to drive its up and down sliding, realizing the up and down sliding of the main unit relative to the outer casing. During installation, the smoke waterfall device can be hidden inside the vehicle's center console; only the top of the smoke waterfall device 100 needs to be exposed on the surface 101 of the vehicle's center console or office desk (e.g., ...). Figure 12 and Figure 13 As shown), a through-hole is created on the surface of the vehicle's center console or office desk to allow the main unit to move up and down. This solves the problem that existing smoke diffusers occupy interior space and affect aesthetics when placed outside the vehicle. Furthermore, the lifting structure does not affect the viewing effect of the visible cavity during use. During use, a drive mechanism causes the cavity at the top of the main unit to protrude upwards from the center console (as shown). Figures 9 to 11As shown in the image, the atomizer is working at this time. The atomized smoke enters the top of the cavity along the smoke inlet channel, and then the smoke flows down the smoke channel to form a smoke waterfall landscape.

[0041] It is understandable that using the smoke waterfall device inside the vehicle's center console is only one of its best applications, not its only applications. No specific limitations are made here. In practice, the smoke waterfall device can also be hidden and installed under a desk, etc. When in use, the main unit can be raised and protruded from the desk surface to reduce its occupation of indoor space and its impact on the overall layout of the room.

The air outlet of the smoke exhaust device 500 is connected to the outside of the outer casing 1. That is, the downward-flowing smoke is discharged downward from the smoke exhaust holes 303 and is absorbed by the smoke exhaust device 500 and discharged outward. In this way, it can be directly discharged to the outside of the vehicle, avoiding the problem of smoke being discharged inside the vehicle obstructing the view of the windshield and condensing into water droplets on the windshield. This improves driving safety and achieves the aesthetic effect of the smoke waterfall landscape without affecting the user experience inside the vehicle.
