Ventilated and temperature-adjustable isolation protective garment

The invention discloses a ventilated and temperature-adjustable isolation protective garment which comprises a protective garment body and a fresh air mechanism connected to the outside of the protective garment body, and an air inlet end allowing external air to enter and an air supply end allowing purified air to be discharged are arranged on a shell of the fresh air mechanism. A filter element cavity, a heat exchange cavity and a fan cavity are sequentially arranged in an air channel between the air inlet end and the air supply end of a shell of the fresh air mechanism, the filter element cavity is filled with a filter element for filtering and purifying flowing air, and the heat exchange cavity is filled with a heat exchange bag for cooling/heating the flowing air in a heat exchange mode. And a miniature high-speed brushless fan for driving air to flow from the air inlet end to the air supply end is arranged in the fan cavity. Purified air entering the protective clothing body can directly exchange heat w
