Intelligent negative pressure generating device for Chinese style double sleeves

The invention relates to the field of medical treatment, in particular to an intelligent negative pressure generating device for a Chinese style double sleeve. The intelligent negative pressure generating device for the Chinese style double sleeves comprises a negative pressure box, an air extracting pump and an adjusting mechanism. The negative pressure box can form a negative pressure cavity. The adjusting mechanism comprises a fixed support, a movable support, a movable piece, two sliding pieces, a plugging mechanism, a pressure adjusting mechanism and a reset mechanism. The blocking mechanism comprises a first check block and a second check block. The pressure regulating mechanism is configured to drive the first stop block to rotate to open the first through groove and then drive the second stop block to rotate to open the second through groove when the moving part descends relative to the moving support. When the sliding rod descends relative to the moving part, the first check block and the second chec
