The air outlet holes 14, the hand outlet 171, the foot outlet 181, and the inlet 15 are all connected to the inside of the wearing space 13.

As shown in fig. 5 and 8, the front side 11 is defined as a position to be positioned on the front side of the human body when worn, and the back side 12 is defined as a position to be positioned on the back side of the human body when worn.

The insertion opening 15 may be in the form of a zipper, and the position of the insertion opening 15 is exemplified in this embodiment at the position where the upper body 17 is located on the front view side 11.

The opening binding section 19 can be an elastic belt type, a buckle type and the like.

The air supply device 2 can be of an air-inflating type, a fan blade type and the like.

The power supply unit 24 may be a mobile power supply, a battery, or the like to provide the operating power of the air supply device 2.

In the embodiment of the present invention, after the opening of the inlet 15, the human body can enter the wearing space 13 through the inlet 15, then the inlet 15 is closed, and the tightening of the tightening sections 19 seals the head, the trunk, and part of the four limbs inside the wearing space 13, the palm can pass through the hand outlets 171, the sole can pass through the foot outlets 181, the air supply device 2 is continuously started, the external air can flow into the air supply device 2 through the air inlet 21, and then flow into the wearing space 13 through the air outlet 22, and the air entering the wearing space 13 through the air supply device 2 provided with the filter layer 23 is filtered, so that there is no need to worry that the air entering the wearing space 13 has dangerous substances (dust, bacteria, virus), and the air continuously flows into the wearing space 13, so the internal pressure is higher than the outside of the garment body 1, so that part of the air is gradually exhausted from the clothes body 1 through the exhaust holes 14, thereby achieving the effect of circulating the air in the wearing space 13, and solving the problem of stuffiness in the protective clothing, and because the exhaust holes 14 continuously exhaust air, the dangerous substances outside the clothes body 1 can not enter the wearing space 13 through the exhaust holes 14, and the transparent window sheet 161 at least corresponds to the eyes of the human body, so that the human body in the wearing space 13 can watch the scene outside the clothes body 1.

From the above, it is known that the invention actually improves the problem of stuffiness inside the protective clothing, and does not need to additionally connect a gas output pipe of an air compressor, a power type inflator and other equipment to inflate the interior of the protective clothing as in the conventional protective clothing, but the invention can lead the gas to circulate in the wearing space 13, can relieve stuffiness compared with the protective clothing which only corresponds to a small part of the human body to enhance the air permeability, and is actually an invention with better performance compared with the conventional protective clothing.

As shown in fig. 4 and 5, the nose cover 16 is recessed into the wearing space 13 at the front side 11 to form a nose-spanning section 162, and the nose cover 16 protrudes outward from the wearing space 13 to form a nose-breathing zone 131 between the nose-spanning section 162 and the upper body 17, so that the hot air exhaled by the human body is high and the hot air can float upward to easily cause the transparent window 161 to fog up corresponding to the eyes of the human body, therefore, the nose-spanning section 162 is disposed over the nose of the human body to prevent the air corresponding to the nose-mouth position from directly flowing to the eyes, so that the transparent window 161 can more accurately correspond to the eyes of the human body, and the visible range is not easily affected by the shaking and misalignment of the head cover 16, and the nose-breathing zone 131 formed by the protruding outward of the head cover 16 corresponds to the nose-mouth position of the human body to prevent the head 16 from excessively fitting the air inlet position of the nose-mouth of the human body to affect breathing, the nose-crossing section 162 and the nose-mouth breathing region 131 are not necessarily formed by the transparent window sheets 161 completely as shown in fig. 4 and 5, but may be formed by the portion of the head cover portion 16 without the transparent window sheets 161 as shown in fig. 7 and 8, or the portion of the head cover portion 16 without the transparent window sheets 161 and the connecting portion of the transparent window sheets 161.

As shown in fig. 1 to 5 and 7 to 10, the plurality of air outlet holes 14 are distributed at the top end of the hood portion 16 and the lower end of the hood portion 16, the portion of the upper body 17 close to the second-hand passing outlet 171 and the portion of the lower body 18 close to the two-foot passing outlets 181, and the air outlet holes 14 are distributed at the above positions, so that when air continuously enters the wearing space 13, the internal pressure gradually increases, and the air gradually flows to the portion with lower resistance, while the portion with lower resistance in the present invention is the air outlet holes 14, for example, the air outlet holes 14 are distributed at a poor position, if the air outlet holes 14 are arranged at the corresponding thighs of the human body, the air is almost discharged from the air outlet holes 14 and hardly flows to the calves, and thus it is known that the distribution positions of the air outlet holes 14 of the present invention can make the air in the wearing space 13 flow to the outside of the human body to the maximum extent, to maximize the benefit of ventilation in relieving stuffiness.

As shown in fig. 1, fig. 3 and fig. 4, the upper body 17 includes a body segment 173 and two sleeve segments 170 connected to each other, the body segment 173 is connected between the head cover 16 and the lower body 18, the second-hand wearing outlet 171 is respectively opened on the two sleeve segments 170, the air blowing device 2 is located at a position of the upper body 17 close to the lower body 18, and when the two sleeve segments 170 are swung down, the air blowing device 2 is adjacent to any one sleeve segment 170 of the two sleeve segments 170, the air blowing device 2 is located at a position such that a wearer can easily replace the power supply unit 24 by only swinging down his/her hand.

As shown in fig. 6, the filter layer 23 of the blowing device 2 is located at the air inlet portion 21, and the filter layer 23 is formed by stacking three filter sheets 231, the three filter sheets 231 are suitable for filtering dangerous substances, and the filtering effect is sufficient without excessively increasing the volume of the blowing device 2.

Wherein the plurality of air outlet holes 14 are respectively provided with a one-way valve, so that the air outside the clothes body 1 can not enter the wearing space 13 through the plurality of air outlet holes 14, thereby preventing the air supply device 2 from having no early warning fault and the power from being exhausted so that dangerous substances enter the wearing space 13 from the outside of the clothes body 1 in the operation.

The transparent window sheet 161 is welded to the head cover 16 at a high frequency, so that the joint between the transparent window sheet 161 and the head cover 16 has excellent toughness and hardness to improve durability.

As shown in fig. 1 to 10, a plurality of filter net sheets 141 are further included, the filter net sheets 141 are distributed outside the clothing body 1 and cover the air outlet holes 14, and a plurality of viruses are infected by the human body without having a disease sign, so that many virus hosts do not perceive the infection of the virus and do not consciously infect the virus to other people, and therefore, a structure is advantageous in that if the human inside the clothing body 1 has the virus, the virus is filtered by the filter net sheets 141 and is not discharged outside the clothing body 1 when the air inside the wearing space 13 is discharged out of the clothing body 1.

As shown in fig. 9 and 10, the head covering portion 16 is movably connected to and separated from the upper body portion 17, the lower end of the head covering portion 16 has a head covering inlet 163, the upper body portion 17 has a head penetrating outlet 172 toward the upper end of the head covering portion 16, and a fluff surface felt 31 and a fluff surface felt 32 are respectively disposed at the inner edge of the head covering inlet 163 and the outer edge of the head penetrating outlet 172, wherein when the head covering portion 16 is connected to the upper body portion 17, the head covering portion 16 covers the outer periphery of the head penetrating outlet 172, and this structure enables the head covering portion 16 and the upper body portion to be movably connected and separated by the fluff surface felt 31 and the fluff surface felt 32, respectively, and has a structure that facilitates the penetration and separation (the arrangement positions of the fluff surface felt 31 and the fluff surface felt 32 are exchanged), and even when the head covering portion 16 is separated from the human body, the air in the wearing space 13 is continuously ejected from the head penetrating outlet 172, at this time, most of the air breathed from the mouth and nose of the human body is ejected from the head-through opening 172, and therefore, it is less likely to inhale dangerous substances even when the head cover part 16 needs to be removed (for example, eating and drinking). The structure in which the hood portion 16 covers the outer periphery of the head-through opening 172 is advantageous in that the air in the wearing space 13 can directly flow from the upper body portion 17 toward the hood portion 16, because if the hood inlet 163 is surrounded by the head-through opening 172, a part of the air directly rushes toward the gap between the hood inlet 163 and the head-through opening 172, increasing the risk of separation of the hood portion 16 from the upper body portion 17, which must be avoided.

As shown in fig. 3, the lower body 18 includes a hip pants section 182 and two pants sections 180 connected to each other, the hip pants section 182 is connected to the upper body 17, the two foot outlets 181 are respectively disposed at the lower ends of the two pants sections 180, and a drain 183 of a movable switch is disposed at the back side 12 of the hip pants section 182, so that the wearer can go to the toilet by opening the drain 183 without taking off the garment 1.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way, and all simple modifications, equivalent variations and modifications made to the above embodiment according to the technical spirit of the present invention still fall within the scope of the technical solution of the present invention.
