Therefore, existing cabinets are generally equipped with small negative pressure fans, which use the air convection and negative pressure ventilation generated by the negative pressure fan to cool and remove dust inside the cabinet, so as to ensure that the electronic components inside the cabinet can work for a long time. However, the traditional cabinet air outlet is fixed in position, and the function it can achieve is to drive the overall airflow circulation in the cabinet. However, after the size of the processor placed in the cabinet changes or the partition is adjusted, it will inevitably affect the overall airflow guidance inside the cabinet, reducing the cooling efficiency, and some indoor or outdoor cabinets are prone to waterlogging when it rains or leaks.

A rotating guide slider that can slide in the passive rotating slideway is fixedly arranged on the inner side wall of the movable sleeve block. The movable sleeve block can be lifted and lowered to drive the rotating guide slider to lift and lower in the passive rotating slideway, and drive the connecting sleeve to rotate when passing through the curved groove part on the passive rotating slideway, so that the connecting port of this section connects the corresponding air duct opening with the air duct, so as to facilitate the airflow in the fixed air duct to enter the air duct through the connecting port to provide airflow for the air duct; The connecting sleeve, the fixed air duct and the movable sleeve block are airtight.

2. A water-utilizing dustproof cabinet as claimed in claim 1, characterized in that: The length of the movable sleeve block in the vertical direction is much greater than the length of the single-section air duct opening in the vertical direction.

3. A water-utilizing dustproof cabinet as claimed in claim 2, characterized in that: A rotation restriction is provided between the connecting sleeve and the inner wall of the connecting groove, that is, a restriction spring is provided between the connecting sleeve and the inner wall of the connecting groove, and the restriction spring can maintain the connecting sleeve in a positional relationship where the connecting port and the air duct opening are staggered when only subjected to the reverse force of the return spring, that is, the connecting sleeve can be driven to rotate only when it slides through the guide between the rotating guide slider and the passive rotating slide.

4. A water-utilizing dustproof cabinet as claimed in claim 2, characterized in that: The air supply system comprises a blast duct which is distributed front to back and symmetrical to each other front to back, an air inlet communicating with the outside is provided at the air inlet of the blast duct, a filter for dust removal and drying is provided at the inlet of the air inlet, a rotating shaft of the blast duct which runs through both sides is rotatably provided in the blast duct, a fan which can rotate in the blast duct is fixedly provided on the rotating shaft, and the outside air can be drawn into the blast duct through the air inlet by the rotation of the fan; The rotating shaft is driven by a motor fixedly arranged in the inner wall at the rear side of the air blast duct; The diameter of the pipe of the air blast duct gradually decreases from the air inlet to the air outlet, and the air blast ducts located on both sides are close to each other and connected at one end and are provided with an air outlet opening facing outward, and a guide nozzle is provided between the air outlet and the air blast duct, that is, the two coaxial air flows in the air blast duct are respectively filled into the air outlet at an angle of 45 degrees under the guidance of the guide nozzle, and the two air flows are contacted at an angle of 90 degrees and ejected out of the air outlet of the air outlet; An air outlet duct is arranged between the air blast ducts, the inlet end of which is connected with the cabinet cavity and the outlet end of which is opened in the rear side wall of the air outlet. When two air flows collide in the air blast duct and are discharged outward, a negative pressure area is formed in the air outlet. The outlet end of the air outlet duct is opened on the negative pressure area in the air outlet, so that the hot air in the cabinet cavity can be extracted through the air outlet duct by the negative pressure.

5. A water-utilizing dustproof cabinet as claimed in claim 4, characterized in that: A one-way conductor is arranged in the air outlet duct, and the one-way conductor includes a fixing ring fixedly arranged on the inner wall of the air outlet duct, and a plastic barrel sheet is fixedly arranged on one end of the fixing ring. The bell mouth direction of the plastic barrel sheet can limit the airflow in the air outlet duct to flow in one direction only.
