Multipurpose thermostatic underwater massager and method for using same

A method of using a multipurpose thermostatic underwater massager comprising the following step:

• A. putting a cushion (3) and an air outlet duct (4) into a water container, injecting hot water into the container, directing a first air outlet (42) and a second air outlet (31) upwards, and sucking said air outlet duct (4) and said cushion (3) on the bottom of the container by means of suckers (8);
• B. controlling a thermostatic principal machine (1) to output different temperatures and air volumes, controlling a duct switch (2) to enable the air flow to pass through said first air outlet (42) and said second air outlet (31) so as to generate air bubbles, which drives the water flow and performs a function of massage in water, and which can bring hot air into the water and performs a function of maintaining the water temperature for a long time;
• after an user gets up from the water, adjusting the temperature and air volume of said thermostatic principal machine (1) and said duct switch (2), holding an air outlet handle (5), using it as a hot air blower, and quickly blowing dry the human body.
