A boss 3 is provided on the cover plate 2. The boss 3 and the cover plate 2 are an integral structure or fixedly or detachably connected. The boss 3 has a cavity 4 inside. An air tower component 5 is provided inside the water tank 1. The air tower component 5 is located directly below the boss 3. The top of the air tower component 5 has an air inlet 6. The horizontal height of the air inlet 6 is higher than the horizontal height of the water tank 1 and is located inside the cavity 4. The boss 3 and the cover plate 2 are an integral structure or fixedly connected, which improves the connection stability of the two structures. Alternatively, the boss 3 and the cover plate 2 are detachably connected, which facilitates the timely disassembly and replacement of the boss 3. The setting of the boss 3 increases the height of the boss 3 part on the cover plate 2. The boss 3 has a cavity 4 inside. The air tower component 5 is located directly below the boss 3. The cavity 4 allows the top of the air tower component 5 in the water tank 1 to be located inside the cavity 4. The air inlet 6 is located on the top of the air tower component 5. The water in the water tank 1 can only reach the height of the water tank 1. The horizontal height of the air inlet 6 is higher than the horizontal height of the water tank 1, which can prevent the water in the water tank 1 from overflowing into the air inlet 6, prevent water from flowing into the air inlet 6, and prevent short circuits to the fan blades installed in the fan outlet 12.

[0040] like Figure 2 As shown, the water tank 1 has a second boss 7 inside. The second boss 7 is either an integral structure with the water tank 1, fixedly connected, or detachably connected. The second boss 7 is arranged parallel to the first boss 3. The second boss 7 is connected to the air tower component 5 and is located directly below the air tower component 5. The second boss 7 is an integral structure with the water tank 1, or fixedly connected, which improves the connection stability of the two structures. Alternatively, the second boss 7 is detachably connected to the water tank 1, which facilitates the timely removal and replacement of the second boss 7. The setting of the second boss 7 increases the height of the second boss 7 part inside the water tank 1. The connection between the second boss 7 and the air tower component 5 increases the horizontal height of the air tower component 5, making the horizontal height of the air inlet 6 on the air tower component 5 higher than the horizontal height of the water tank 1, thus preventing water in the water tank 1 from overflowing onto the air inlet 6.

[0041] like Figure 2As shown, the gas tower component 5 includes a first gas tower 8 and a second gas tower 9. The bottom of the first gas tower 8 and the top of the second gas tower 9 are an integral structure or fixedly connected.

The horizontal height of the top of the second gas tower 9 is lower than, equal to or higher than the horizontal height of the water tank 1. The bottom of air tower 8 and the top of air tower 9 are an integral structure or fixedly connected, which improves the connection stability of the two structures. The boss 3 is set parallel to both air tower 8 and air tower 9, and all three are located on the same straight line, so that the air inlet 6 on air tower 8 is located in the cavity 4 of boss 3. The horizontal height of the top of air tower 9 is lower than the horizontal height of water tank 1, and the horizontal height of the top of air tower 8 is higher than the horizontal height of water tank 1, so as to prevent water in water tank 1 from flowing into the air inlet 6. Alternatively, the height of the top of air tower 9 is equal to or higher than the horizontal height of water tank 1. Air tower 8 is located on top of air tower 9, which can directly prevent water in water tank 1 from flowing into the air inlet 6.

[0042] like Figure 3 As shown, the bottom of the water tank 1 is provided with a base plate 10. The base plate 10 is detachably connected to the water tank 1, fixedly connected, or is an integral structure. The bottom of the base plate 10 has a groove 11, and a fan outlet 12 is provided in the middle of the groove 11. The horizontal height of the top of the groove 11 is higher than the horizontal height of the base plate 10. The groove 11 is located directly below the boss 7. The top of the groove 11 is detachably connected to the bottom of the boss 7. The base plate 10 and the water tank 1 are an integral structure or fixedly connected, which improves the stability of the two structures. The base plate 10 and the water tank 1 are detachably connected, which facilitates timely disassembly for replacement of internal parts. The fan outlet 12 is provided in the middle of the groove 11. The fan outlet 12 can be equipped with a fan blade to deliver air to the air inlet 6. The air enters the water tank 1 from the air inlet 6, forming an airflow, thereby carrying the atomized water vapor generated by the ultrasonic vibration of the vibrating part 22 to the air outlet 13 and spraying it out from the air outlet 13 to humidify the interior of the vehicle.

[0043] The top of the groove 11 is higher than the bottom plate 10. The bottom of the second boss 7 is connected to the top of the groove 11. The groove 11 raises the height of the second boss 7 inside the water tank 1, thereby raising the air tower component 5 and further preventing water in the water tank 1 from flowing into the air inlet 6. The groove 11 and the second boss 7 are detachably connected, making it easy to disassemble and assemble them. The groove 11 and the second boss 7 are fixedly connected, making their structures stable.

[0044] like Figure 1 and 7As shown, an air outlet 13 is rotatably connected to the cover plate 2. The cover plate 2 has a notch 14, and the lower end of the air outlet 13 is located at the notch 14. The cover plate 2 has a stepped surface 15, and the lower end of the air outlet 13 abuts against the stepped surface 15. The air outlet 13 is used to spray water vapor from the water tank 1 into atomized form to create a humidification effect. The air outlet 13 can rotate on the cover plate 2 to better adapt to the humidification effect of different environments. The lower end of the air outlet 13 abuts against the stepped surface 15, which has a limiting function, keeping the air outlet 13 within the notch 14, improving the stability of the structure and facilitating the rotation of the air outlet 13 on the cover plate 2.

The lower end of the lower nozzle 17 has a hook 18 that abuts against the bottom surface of the cover plate 2. The upper end of the lower nozzle 17 has a connecting groove 19, and the lower end of the upper nozzle 16 has a protrusion 20. The protrusion 20 is inserted into or fixedly connected to the connecting groove 19. The hook 18, located at the bottom of the lower nozzle 17, abuts against the bottom surface of the cover plate 2, ensuring a stable connection between the lower nozzle 17 and the cover plate 2 and preventing the lower nozzle 17 from detaching from the cover plate 2. The connecting groove 19 is inserted into the protrusion 20, facilitating the disassembly of the upper nozzle 16 and the lower nozzle 17. The fixed connection between the connecting groove 19 and the protrusion 20 improves the stability of the structure.

[0046] like Figure 1 As shown, the cover plate 2 has two fan mounting ports 21, which are arranged opposite to each other. Air outlets 13 are located at the front of each fan mounting port 21. The fan mounting ports 21 are used to install fans. The cover plate 2 has two oppositely arranged fan mounting ports 21, which can accommodate two fans to facilitate airflow to people on both sides.
