The weak static pressure buoyancy generating device according to claim 7, characterized in that: The elastic mechanism includes two mounting blocks respectively fixedly mounted on the cleaning strip and the hinge block, a same elastic rope is fixedly mounted between the two mounting blocks, the elastic rope is located on one side of the box body, two arc-shaped guard plates are symmetrically fixedly mounted on one side of the box body close to the reduction box, the arc-shaped guard plates are adapted to the reduction box, and the arc-shaped guard plates are used to prevent the cleaning strip from being stuck on the reduction box when the cleaning strip moves.
10. A weak static pressure buoyancy generating process using the weak static pressure buoyancy generating device according to any one of claims 1 to 9, characterized in that: The following steps are involved: S1: starting the high voltage generator, the high voltage generator generates a high voltage on the electrode and the ionization needle through the wire, and the ionization needle with high voltage ionizes the air below the air outlet to generate static electricity; S2: The weak wind mechanism is started, and the weak wind mechanism sucks the air outside the box from the air inlet. The sucked air is filtered by the filter and enters below the air outlet, and then pushes the ionized air to move slowly upward, thereby generating weak static pressure buoyancy.
