Positive pressure protective clothing with improved ventilation structure

The utility model relates to the technical field of positive pressure protective clothing, and discloses positive pressure protective clothing with an improved ventilation structure. The one-piece suit comprises a one-piece suit and a high-pressure air supply device, and further comprises a first one-way valve which is arranged at the one-piece suit and used for conveying air in a pipeline of the high-pressure air supply device into the one-piece suit, and a second one-way valve which is arranged at the one-piece suit and used for conveying air in the one-piece suit to the outside; the first one-way valve and the second one-way valve each comprise an air inlet and an air outlet, and the end of an air supply pipe of the high-pressure air supply device is hermetically connected to the air inlet of the first one-way valve. Through the arrangement, the probability that air in the protective clothing flows back into the hose of the high-pressure air supply device can be well reduced. 本实用新型涉及正压防护服技术领域，公开了一种改进换气结构的正
