Detailed Description

As shown in fig. 1 and 2, a biosafety isolation helmet mainly comprises a helmet main body 1, a front transparent cover 2 and an elastic neck 3, wherein the helmet main body 1 and the front transparent cover 2 can be made of plastic materials such as PVC, the elastic neck 3 can be made of soft and elastic rubber materials, and is vulcanized with the helmet main body 1 and the front transparent cover 2 into an integral structure; an air supply filtering device 10 is arranged at the top of the helmet main body 1, an air duct 6 is arranged inside the helmet main body 1, and an outlet of the air supply filtering device 10 is communicated with an air outlet 17 at the front end of an inner cavity of the helmet through the air duct 6; the rear end of the helmet main body 1 is provided with a power supply control device 5; the power supply control device 5 is connected with the fan 14 in the air supply filtering device 10, power is provided for the fan 14, meanwhile, the air exhaust amount of the fan can be adjusted, and the comfort level is improved while the safety pressure difference is ensured.

The structure of the air supply filtering device 10 is that a fan 14 is arranged in an air supply cover 16, and a primary filter 11 and a middle filter 12 are sequentially arranged between the inlet of the air supply cover 16 and the fan 14; a clean pressure box 15 is arranged at the outlet of the fan 14, and a high-efficiency filter 13 is arranged at the tail end of the air supply cover 16 and is positioned at the inlet of the air duct.
