▎ 摘　　要

NOVELTY - The meter has a graphene heating sheet (9) which is arranged on the inner wall of the hatch (2). The bed surface of the bed frame (1) is recessed downward to form a cavity. The vibration device is located in the cavity and flush with the bed surface. A heating mattress (6) is laid flat on the bed. The horn (12) is arranged on the bed. The peripheral edge of the headboard of the bed frame is raised to form a peripheral edge. A gas nozzle (16) is arranged on the edge. The negative ion generator is arranged on the bed and connected with the gas nozzle. The magnetic field generating module is arranged on the bed at a position below the heating mattress. A control circuit board is arranged in the bed and respectively connected with the far-infrared heating device (5), heating mattress, vibration device, ozone generator (8), graphene heating sheet, negative ion generator, magnetic field generating module and horn. USE - Multifunctional entropy subtraction meter used for health care physical therapy. ADVANTAGE - The body temperature rise is made uniformly, the blood circulation is accelerated, which encourages people to perspire, and helps to remove harmful substances in the body. The vibration of the vibration device relaxes muscles, enhances blood circulation, relieves fatigue, and has a massage effect. The magnetic field generating module emits quantum magnetic fields with different pulse frequencies to act on the human body, which has a magnetic therapy effect and improves health care effects. The fresh air containing negative oxygen ions are provided through the negative ion generator, which is beneficial to human health. The user listen to music during use, which brings people more comfortable enjoyment. The bed surface is sterilized and deodorized by an ozone generator. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of the entropy subtraction meter when the hatch is opened.
