Voice-control intelligent mattress with hardness capable of being adjusted in multiple stages

A voice-control intelligent mattress with hardness capable of being adjusted in multiple stages, comprising:

• an upper-layer soft pad,
• a hardness-adjusting device, and
• a lower layer or a multi-layered hard pad that are sequentially arranged from top to bottom, wherein the hardness-adjusting device comprises two adjusting units symmetrically arranged with the transverse center line of the mattress, and a voice-control module connected with each of the two adjusting units through a wire for controlling the starting and stopping of each of the two adjusting units, wherein two adjusting frames connected with each of the adjusting units are symmetrically arranged on the two sides of each adjusting unit, wherein an elastic mesh belt installed on the adjusting frames is tightened or loosened along the expansion or contraction of the adjusting frames
• wherein the adjusting frame comprises a longitudinal chain bar, and transverse adjusting rods that are perpendicular to and connected with the longitudinal chain bar, wherein a transverse adjusting rod is arranged along the axis direction of the threaded rod and is in threaded connection with the threaded rod, wherein a limiting block is arranged at the position where chain units of the longitudinal chain rod are hinged, thereby allowing the longitudinal chain bar to bend downwards and be rolled.
