Abstract:
A rapid inflating and discharging device (100) for a protective suit and an intelligent multi-purpose protective suit (200). The inflating and discharging device (100) comprises: an outer cylinder (1), provided with a first hole (11); an inner cylinder (2), provided in the outer cylinder (1), provided with a second hole (25), and slidable between a first position and a second position, wherein in the first position, the second hole (25) is aligned with the first hole (11), and in the second position, the second hole (25) is offset from the first hole (11) and is covered by an inner wall of the outer cylinder (1); a blade (3) provided in the inner cylinder (2); a motor (4) for driving the blade (3); and a pressing device (5) for pressing the inner cylinder (2) towards the first position. The inner cylinder (2) further comprises a third opening (24), and the third opening (24) is provided with a one-way valve (23), only allowing a pressurized gas to flow from the inner cylinder (2) through the third opening (24) to the outside, and preventing the pressurized gas from flowing in an opposite direction. The protective suit (200) having the rapid inflating and discharging device (100) is rapidly inflated for protection, and the gas can be rapidly discharged after use, such that the protective suit (200) is flat again, facilitating storage. The reusable protective suit (200) reduces costs of use.
