This invention provides a folding cabinet with a vacuum compression bag, comprising a cabinet body and a vacuum compression bag, the vacuum compression bag including a bag opening. The cabinet body includes an interlayer mechanism, a folding mechanism, and a support mechanism. The interlayer mechanism includes a first interlayer support member and a second interlayer support member. The first interlayer support member includes a first mounting frame and a cover plate, with the bag opening connected to the first mounting frame. The folding mechanism is supported between the first and second interlayer support members and includes an unfolded state, a retracted state, and several folded states. The support mechanism is adapted to continuously provide driving force so that the folding mechanism tends to turn into the unfolded state. In its
natural state, the folding structure remains in the unfolded state. When the vacuum compression bag is vacuumed, the folding mechanism can change from the unfolded state to a folded state or a retracted state until it is in
force equilibrium. This invention achieves coordinated deformation of the cabinet structure and the bag body through the folding structure, allowing the cabinet body to change synchronously with the
volume change of the vacuum compression bag.
