[0002] The air outlet of the fan of the dust suction vehicle is connected with two channels through an adapter box body, and the air outlets of the two channels cannot be opened simultaneously. Most of the existing air outlet conversion devices of dust suction vehicles are manual or push rod direct connection type. The manual type requires manual participation to achieve air outlet conversion, with relatively troublesome operation, time-consuming and laborious. The push rod direct connection type has a simple structure, but is only applicable to the single-channel sealed opening. For the relatively vertical 90° two-way channels, the air outlets of both channels need to ensure good sealing effects.

[0003] For example, patent CN215629665U discloses an air outlet conversion device of a dust suction vehicle, including an electric push rod. The output end of the electric push rod is connected with a rack, the rack is in transmission connection with a gear, the wheel shaft of the gear extends into the box body of the adapter box, and the wheel shaft is connected with a sealing plate. The sealing plate switches between two air outlets as the wheel shaft rotates to seal different air outlets. However, when the sealing plate of this air outlet conversion device is damaged, it is not convenient to quickly maintain it, which increases the maintenance cost of the air outlet conversion device and also reduces the maintenance efficiency of the air outlet conversion device, and is not convenient for users to use.
