Description

TECHNICAL FIELD

[0001] The utility model relates to the field of folding bed canopy, specifically relates to a bed canopy folding exhaust device. BACKGROUND

[0002] Because the bed canopy has rubber strip structure at the bottom, it is different from the folding of the bed sheet, and it will often be puffed up in the folding process, which will make it difficult to fold in half when the puffed up bed canopy is folded again, because the puffed up area will block the bed canopy folded again, that is, it will cause the folding to be impossible. Therefore, the folded bed canopy needs to be exhausted to avoid the smooth folding again. However, the folded bed canopy is full of air due to its puffed up, and it is easy to be squeezed out when extruding, which may cause the risk of explosion. If it is slowly squeezed, the working time of the device will be increased. Therefore, a bed canopy folding exhaust device needs to be designed, which can extrude and exhaust the folded bed canopy, and can also not squeeze the bed canopy in the process of fast extrusion and exhaust.
