Document Type and Number:
WIPO Patent Application WO/2018/018581
Kind Code:
A1
Abstract:
A cooling stool for a classroom, comprising a stool panel (1) and four support legs (2). A metal plate (3) is provided below the stool panel. The metal plate is fixedly connected to the four support legs. A cooling bag (4) is provided on an upper surface of the metal plate. A movable cover plate is rotationally connected to a side of the upper surface of the metal plate. The stool panel comprises a frame (10) for fixing the support leg and a flexible pad (11) disposed in the middle of the frame. The flexible pad is provided with a plurality of ventilation holes. The invention further comprises an air tube (5) disposed between the flexible pad and the cooling bag. The air tube comprises an air inlet (50) and an air outlet (51) disposed at two ends of the air tube, and an air bladder located at a central section of the air tube. The air inlet is provided with a unidirectional air inlet valve. The air outlet is provided with a unidirectional air outlet valve. The metal plate is provided with a through hole (31) aligned with the air inlet. When a user sits on the stool, and when the air bladder is compressed and returns to an initial form, the air inlet then allows air to enter and injects the air into the cooling bag to cool the air. When the air bladder is compressed again, the air is discharged from the air outlet and passes through the holes on the flexible pad, providing excellent breathability. The invention has a simple overall structure and a low cost.
