the right switching plate (155) is arranged between the right air inlet (1622) and the mounting plate (151), a right air vent (1551) is formed in the right switching plate (155), and the right switching plate (155) is in transmission connection with the right driver (152) to enable the right switching plate (155) to slide in a reciprocating mode in the Y-axis direction under the driving of the right driver (152), so that the right air vent (1551) is alternately communicated with the right air suction port (1513) and the right air blowing port (1515).
