Description

The present invention relates to protective clothing that prevents dust, bacteria, or viruses from entering the protective clothing and protects the safety of the wearer.

Protective clothing is now a very important product, an area where dangerous substances (dust, bacteria, viruses) are often easily invaded by related workers due to the development of science and technology and medical progress. When working in (for example, quarantine, virus research, etc.), wearing protective clothing prevents dangerous substances from entering the human body.

However, while protective clothing on the market effectively blocks dangerous substances, it is extremely poorly breathable, and workers wearing protective clothing can easily retain heat and feel uncomfortable. .. Therefore, protective clothing for improving the problem of heat retention has appeared on the market, and in the conventional patent documents, for example, there is a description of "protective clothing having a ventilation function" in Patent Document 1 below. In this plan, ventilation structures are added to the armpits and the back of the knees, but the ventilation is strengthened only in the parts where the human body bends well, and the problem of heat retention at the trunk, face, etc. is alleviated. Not. Alternatively, for example, there is a description of "breathable pneumatic protective clothing" in Patent Document 2 below. In this plan, a gas input port is provided in the protective suit, and when using it, the gas output pipe of equipment such as an air compressor and a powered air supply device must be connected separately to supply air to the inside of the protective suit. It was difficult to apply it in an environment where the workers move over a wide area because the actions of the workers are restricted because they are connected separately.

Hereinafter, embodiments of the present disclosure will be described with reference to the drawings. The present disclosure is not limited to the following embodiments, and various forms may be adopted as long as they belong to the technical scope of the present disclosure.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. First, as shown in FIGS. 1 to 6, the protective clothing defines the front side 11 and the back side 12, has a wearing space 13 inside, and has a plurality of exhaust holes 14 and wear that can be opened and closed movably. Further having an entrance 15, including a head mask portion 16, an upper body portion 17, and a lower body portion 18, the upper body portion 17 is connected between the head mask portion 16 and the lower body portion 18, and the head mask The portion 16 is provided with a transparent window 161 on the front side 11, the upper body portion 17 has two cuffs 171 and the lower body portion 18 has two hem openings 181. The two cuffs 171 and the two cuffs 171. A protective clothing body 1 having a hem opening 19 provided on the peripheral edge of the hem opening 181 and a protective clothing body 1 attached to the protective clothing body 1, the intake unit 21, the exhaust unit 22, the filter layer 23, and the power supply unit. The intake unit 21 communicates with the wearing space 13, and the filter layer 23 includes an air supply device 2 used for filtering the air sent into the wearing space 13. ..

Each of the exhaust holes 14, the cuffs 171 and the hem, and the wearing inlet 15 communicate with each other inside the wearing space 13.

Further, as shown in FIGS. 5 and 8, the defined front side 11 is located on the front side of the human body when worn, and the defined dorsal side 12 is located on the back side of the human body when worn. It is a place.

The wearing entrance 15 is of a line fastener type, and the position of the wearing entrance 15 is taken as an example in which the upper body portion 17 is located on the front side 11 in this embodiment.

The hem tightening 19 is an elastic band type, a button type, or the like.

The air supply device 2 is a pump type, a fan type, or the like.

The power supply unit 24 provides electric power required for operating the air supply device 2 by means of a mobile battery, a battery, or the like.

Following the above contents, the implementation method of the present invention will be described in more detail. After opening the wearing entrance 15, the human body is allowed to enter the wearing space 13 from the wearing entrance 15, then the wearing entrance 15 is closed, and each hem closure 19 is tightened to wear the head, trunk, and partial limbs in the wearing space 13. Enclose inside, put your hands out of each cuff 171 and put your feet out of each hem 181. Subsequently, the air supply device 2 is activated, and after the external air is made to flow into the air supply device 2 from the intake unit 21, it is made to flow into the wearing space 13 from the exhaust unit 22. The air supply device 2 is provided with a filter layer 23 for filtering the air entering the wearing space 13, which contains dangerous substances (dust, bacteria, viruses) in the air entering the wearing space 13. You don't have to worry. By continuously inflowing air into the wearing space 13, the internal pressure becomes higher than the outside of the protective clothing body 1, and partial air is gradually discharged from each exhaust hole 14 to the outside of the protective clothing body 1. As a result, the effect of air circulation in the wearing space 13 is achieved, and the problem that heat is trapped inside the protective clothing is solved. Further, since each exhaust hole 14 continuously exhausts air, dangerous substances outside the protective clothing body 1 do not enter the inside of the wearing space 13 from each exhaust hole 14. The transparent window 161 at least corresponds to the eyes of the human body so that the human body inside the wearing space 13 can see the scenery outside the protective clothing body 1.

As can be seen from the above contents, the present invention surely improves the problem of heat buildup inside the protective clothing, and like the conventional protective clothing, the gas output pipe of equipment such as an air compressor and a powered air supply device. There is no need to connect the air separately to supply air to the inside of the protective suit. Since the present invention circulates gas in the wearing space 13, the present invention cools the heat contained in the protective clothing more than the conventional protective clothing, as compared with the protective clothing that corresponds to only a part of the human body and has enhanced breathability. Is definitely an invention with excellent performance.

Further, as shown in FIGS. 4 and 5, the head mask portion 16 forms a concave area 162 by retracting the front side 11 portion toward the inside of the wearing space 13, and the head mask portion 16 is formed. A breathing zone 131 is formed in the wearing space 13 by raising a portion between the concave area 162 and the upper body portion 17 toward the outside. Since the heat of the gas exhaled by the human body is high and the hot air rises and the part of the transparent window 161 corresponding to the human eye becomes cloudy, the structure of the concave area 162 is straddled over the nose of the human body to correspond to the nose opening. Prevents the air at the position from flowing directly toward the eyes, makes the transparent window 161 correspond more accurately to the eyes of the human body, and makes it difficult for the swing of the head mask portion 16 and the misalignment of the eyes to affect the visible range. There is. Further, the breathing zone 131 formed by raising the head mask portion 16 outward corresponds to the position of the nose and mouth of the human body, and the head mask portion 16 corresponds to the air supply position of the nose and mouth of the human body. It is prevented from sticking strongly to the breathing so as not to affect the breathing, and more air is allowed to flow into the formed breathing zone 131 to facilitate smooth breathing. The concave area 162 and the breathing zone 131 do not necessarily have to be completely composed of the transparent window 161 as shown in FIGS. 4 and 5, and the transparent window 161 of the head mask portion 16 is not provided as shown in FIGS. 7 and 8. It may be composed of a portion, or may be composed of a portion of the head mask portion 16 not provided with the transparent window 161 and a connecting portion of the transparent window 161.

Further, as shown in FIGS. 1 to 5 and 7 to 10, the plurality of exhaust holes 14 are arranged at the upper end of the head mask portion 16 and the lower end of the head mask portion 16, and the upper body portion 17 is arranged. It is close to the two cuffs 171 and the lower body 18 is close to the two hem 181s. When each exhaust hole 14 is arranged at the above-mentioned position and air is continuously allowed to enter the wearing space 13, the internal pressure gradually increases, and at this time, the air gradually flows toward the portion having low resistance. There are exhaust holes 14 in the portion where the resistance of the present invention is low, and to give an example in which the arrangement position of the exhaust holes 14 is bad, the exhaust holes 14 are opened at the locations corresponding to the thighs of the human body, and in other cases, the air is in the thighs. Is discharged from the exhaust hole 14 when flowing through the air, and it becomes difficult for the air to continuously flow to the calf portion. As can be seen from this, the arrangement positions of the exhaust holes 14 of the present invention maximize the air in the wearing space 13 to flow into each position outside the human body, and maximize the effect of cooling the heat trapped by the air flow.

A one-way valve is provided in each of the plurality of exhaust holes 14 to prevent air outside the protective clothing body 1 from entering the wearing space 13 through the plurality of exhaust holes 14, and to supply air during work. The device 2 unexpectedly breaks down, power is consumed, and a dangerous substance is prevented from entering the wearing space 13 from the outside of the protective clothing body 1.

Further, as shown in FIGS. 9 and 10, the head mask portion 16 is movably connected to and separated from the upper body portion 17, and a head mask inlet 163 is arranged at the lower end of the head mask portion 16 to form the upper body portion 16. The portion 17 has a head outlet 172 at the upper end toward the head mask portion 16, and has a female hook-and-loop fastener 31 and a male hook-and-loop fastener 32 installed on the inner edge of the head mask inlet 163 and the outer edge of the head outlet 172, respectively. I have more. When the head mask portion 16 is connected to the upper body portion 17, the head mask portion 16 covers the outer circumference of the head outlet 172. This structure has the advantage of achieving the purpose of movably connecting and separating the head mask portion 16 and the upper body portion by the female hook-and-loop fastener 31 and the male hook-and-loop fastener 32, respectively, and facilitating attachment / detachment (female hook-and-loop fastener 31 and). The installation position of the male hook-and-loop fastener 32 is adjustable). Further, when the head mask portion 16 is detached from the human body, the air in the wearing space 13 is continuously ejected from the head outlet 172, and most of the air breathed through the nose and mouth of the human body is ejected from the head outlet 172. When the head mask portion 16 is taken off (for example, eating or drinking water), it becomes difficult to inhale dangerous substances. The advantage of the structure in which the head mask portion 16 covers the outer circumference of the head outlet 172 is that the air in the wearing space 13 flows directly from the upper body portion 17 toward the head mask portion 16, and the head mask inlet 163 is surrounded by the head outlet 172. This avoids a situation in which partial air flows directly into the gap between the head mask inlet 163 and the head outlet 172, increasing the risk of separation between the head mask portion 16 and the upper body portion 17. is there.
