A first switch part 18 for controlling the on-off between the first sub-groove 701 and the second sub-groove 702 is arranged in the drainage groove 7. By making the drainage groove 7 include the first sub-groove 701 connected to the first part 1301, and the second sub-groove 702 connected to the second part 1302, and the atomizing part 21 is arranged in the second sub-groove 702, it is convenient for the atomized gas to enter the air intake channel 6 through the second part 1302.

[0056] Furthermore, in this embodiment, by providing the first switch 18 for controlling the on-off between the first sub-slot 701 and the sub-slot in the drainage groove 7, it is convenient to flexibly control whether to humidify the cockpit. When the cockpit does not need to be humidified, the first switch 18 can be closed. When the cockpit needs to be humidified, the first switch 18 can be opened to connect the first sub-slot 701 with the second sub-slot 702, so that the water in the first sub-slot 701 can enter the second sub-slot 702, and can enter the air inlet channel 6 after being atomized by the atomizing part 21.

[0057] It should be noted that the first switch unit 18 in this embodiment can be a switch valve or other valve structure commonly used in the prior art, which can control the connection between the first sub-slot 701 and the second sub-slot 702. And the atomization unit 21 can be an atomization sheet commonly used in the prior art, and its structure will not be described in detail here.

By connecting the drain port 703 with the first sub-groove 701, it is convenient to discharge the water entering the drain groove 7 in time, and there is no need to control the action of the first switch unit 18, and the operation is simple. By providing the second switch unit 19, it is convenient to control the opening and closing of the drain port 703. In addition, by providing the first liquid level detection unit, it is convenient to detect the amount of water in the first sub-groove 701.

[0059] In a specific implementation, the first liquid level detection unit may include a first liquid level sensor 15 disposed near the top of the first sub-trough 701, and a second liquid level sensor 16 disposed near the bottom of the first sub-trough 701, so that the first liquid level detection unit can detect whether there is more or less water in the first sub-trough 701. When there is more water in the first sub-trough 701, the second switch unit 19 can be opened or its opening can be increased so that the water in the first sub-trough 701 can flow out.

[0060] It should be noted that the first liquid level sensor 15 and the second liquid level sensor 16 can be selected from the liquid level sensors commonly used in the prior art, and will not be described in detail here. In addition, in this embodiment, the drain port 703 of the drain groove 7 is connected to the first sub-groove 701, and a first liquid level detection unit is provided in the first sub-groove 701, which is only a preferred implementation. In addition, in other embodiments, the drain port 703 can also be selected to be connected to the second sub-groove 702.

A third switch unit 20 is provided between the water tank 22 and the drain groove 7, and the third switch unit 20 is used to control the connection and disconnection between the water tank 22 and the drain groove 7. By providing the water tank 22, when there is less water in the drain groove 7, water can be supplied to the drain groove 7 through the water tank 22, so that when there is a need for humidification in the cab, the amount of water in the drain groove 7 can meet the atomization demand.

[0062] It is worth noting that the second switch unit 19 and the third switch unit 20 mentioned above can adopt valve structures such as stop valves commonly used in the prior art, which can control the on-off of the passage and adjust the flow in the passage.

[0065] When the vehicle air conditioning air intake structure of this embodiment is in use, the two water absorbing parts can work alternately to absorb rainwater entering the air intake channel 6. After the water absorbing part is squeezed, the squeezed water can enter the drainage groove 7. If it is raining and there is no need to humidify the cab, the water entering the drainage groove 7 can be directly discharged through the drainage port 703. At this time, the opening of the second switch part 19 can be controlled to store a part of the water in the drainage groove 7 for subsequent use.

[0066] If there is a need for humidification in the cab under rainy conditions, the second switch unit 19 can be controlled to retain some water in the first sub-slot 701, and the first switch unit 18 can be opened to connect the first sub-slot 701 with the second sub-slot 702, and then the water entering the second sub-slot 702 can be atomized by the atomization module, and the atomized gas can enter the air inlet channel 6 to humidify the cab. In addition, in non-rainy conditions or when there is less water in the drainage groove 7, the third switch unit 20 can be opened to allow the water storage tank 22 to supply water to the drainage groove 7, and then the water can be atomized by the atomization unit 21 to achieve the humidification operation of the cab.
