This is a ventilated purification bed with new technology, which relates to spring bed technology, including the bed body. One end of the bed body is fixedly installed with a headboard, and also includes a support assembly and an inner frame plate. The assembly includes multiple sets of strip-shaped wall grooves set on the inner wall at the corner of the bed body, and each set of strip-shaped wall grooves is slidably connected with a triangular cavity sleeve in the vertical direction; when the sliding column moves in the present invention, it can drive push-pull the plates move synchronously. This bed has adopted a brand-new technology. When someone is lying on the spring bed, the hollow bracket moves down to act on the air duct, thereby triggering the negative ion generator, increasing the content of negative ions in the air, which is of great benefit to human health. And it can also prolong the service life of the spring bed.
