Adjustable bionic pillow tool

Abstract

The present invention discloses an adjustable bionic pillow tool. The contact surface of the pillow core is provided with grooves and/or bumps. The grooves/bumps are arranged crosswise to form finger-like protruding support parts. The grooves or the bumps are provided crosswise on the contact surface of the pillow core, which can form a diffusion groove and can have ventilation and air permeability while having support. The staggered grooves or bumps form finger-like protrusions, which can reduce squeeze on blood vessels and tissues, solve the problem of compression in a traditional pillow tool after the pillow tool is compacted in a whole piece, and can form a massage effect on the contact part. A support layer of a bottom airbag is provided, so that the height, tilt degree, softness and hardness of the pillow tool can be conveniently adjusted by inflating and deflating the airbag.
