[0019] In order to understand the technical features and practical effects of the present application in detail, and to realize the creation content, the preferred embodiments as shown in the drawings are further described as follows:

[0020] As shown in Figures 1 to 4 The first preferred embodiment of the positive pressure protective clothing of the present application includes a clothing body 10, a joint 20 and a fixing ring 30. The joint 20 is used to combine with a pipe body 90, so that the filtered air can be input into the inside of the clothing body 10 through the pipe body 90 and the joint 20. The fixing ring 30 is used to combine with the joint 20, so that the joint 20 can be detachably fixed on the clothing body 10.

[0021] The protective effect of the clothing body 10 can be separated from the external environment by forming a polypropylene, polyethylene or other coating on the surface, or by selecting a material with good impermeability and corrosion resistance. For specific reference, the existing protective clothing can be used. The clothing body 10 can have different wearing designs according to the need for protection, protection requirements, etc. Figure 1 and Figure 4As shown, in the first preferred embodiment of the present invention, the garment body 10 is a half-body protective suit composed of a head cover 11, an upper garment 12, a lower hem 13, and two sleeves 14. The head cover 11 is connected to the top of the upper garment 12, and the two sleeves 14 are connected to the sides of the upper garment 12, which can separate the upper body of the person from the external environment. The lower hem 13 is connected to the bottom of the upper garment 12, and the lower hem 13 forms an opening away from the bottom of the upper garment 12, allowing the person to put on the positive pressure protective suit through the opening.

[0022] like Figure 1 and Figure 3 As shown, the connector 20 can be installed on the garment body 10. Specifically, the garment body 10 has an air inlet 101 corresponding to the connector 20. The air inlet 101 connects the interior and exterior of the garment body 10. Figure 2 and Figure 3 As shown, the connector 20 includes a base 21, a connecting part 22 and a connecting part 23 connected in sequence. The base 21 is located inside the garment body 10, and the outer diameter of the base 21 is larger than the diameter of the air inlet 101. The connecting part 22 passes through the air inlet 101, so that the connecting part 23 is located outside the garment body 10, so as to connect with the aforementioned tube 90.

[0023] like Figure 2 and Figure 3 As shown, the connector 20 also includes an air inlet channel 24, which extends from one end of the connector 20 to the other end and sequentially passes through the base 21, the connecting portion 22, and the connecting pipe portion 23, thereby connecting the interior and exterior of the garment body 10. After the connecting pipe portion 23 is connected to the aforementioned tube 90, filtered air can be introduced into the interior of the garment body 10 from the aforementioned tube 90 through the air inlet channel 24.

[0024] like Figure 3 As shown, the fixing ring 30 can be threadedly engaged with the connecting portion 22 of the connector 20. Specifically, the connecting portion 22 has an external thread 221 on its outer periphery, and the fixing ring 30 has an internal thread 31 on its inner peripheral wall. The connecting portion 22 and the internal thread 31 are engaged through the external thread 221 and the internal thread 31. At this time, the part of the garment body 10 around the air inlet 101 102 will be clamped between the fixing ring 30 and the base 21 of the connector 20. In this way, the connector 20 can be fixed to the garment body 10, and a sealing ring and the part of the air inlet 101 102 can be clamped together between the fixing ring 30 and the base 21 to form an airtight assembly, which can prevent harmful gases from the external environment from entering the interior of the garment body 10 from between the air inlet 101 and the connector 20.

[0025] In actual installation, firstly, the connector 20 is placed inside the garment body 10, and the connecting part 23 and the connecting part 22 of the connector 20 are extended out of the air inlet 101 to the outside of the garment body 10. Since the outer diameter of the base 21 is larger than the diameter of the air inlet 101, the base 21 can abut against the periphery 102 of the air inlet 101 and remain inside the garment body 10. Then, the fixing ring 30 is screwed into the connecting part 22. The fixing ring 30 and the base 21 of the connector 20 are clamped to the periphery 102 of the air inlet 101 from the inside and outside sides, and the installation is completed, fixing the connector 20 to the garment body 10.

[0026] When personnel need to wear the positive pressure protective suit, such as when spraying pesticides or disinfecting indoor spaces, after donning the suit, an air supply device should be prepared. This air supply device draws in air from the external environment and filters it. The aforementioned tube 90 extends from this air supply device. Figure 4 As shown, after the tube 90 is connected to the connector 20, the filtered air can be introduced into the interior of the garment body 10, making the pressure inside the garment body 10 higher than that outside and thus creating a positive pressure state. This creates a tendency for gas to flow from the interior of the garment body 10 to the exterior, which can prevent people from feeling stuffy and prevent harmful gases from the outside environment from entering the interior of the garment body 10, thus ensuring the safety of the personnel.

[0027] Specifically, in the first preferred embodiment of this utility model, the positive pressure protective clothing is further provided with a waist belt 51, which can be tightened between the upper garment 12 and the lower hem 13. Each sleeve 14 has a drawstring 141 at the cuff, thereby tightening the garment body 10 on the person, separating the inside of the garment body 10 from the outside, and allowing it to communicate with the air supply device only through the connector 20 and the tube 90, thereby achieving a positive pressure state inside the garment body 10, which can achieve the effect of blocking harmful gases. The garment body 10 also has multiple pressure relief ports 103, which are located on the head cover 11 and the two sleeves 14 near the cuffs. The gas inside the garment body 10 can flow out from the pressure relief ports 103 to avoid excessive pressure.

[0028] In addition, in the first preferred embodiment of the present invention, the positive pressure protective clothing also includes a plurality of cover cloths 40, each of which is movably disposed on the garment body 10 and covers one of the corresponding pressure relief ports 103, which can prevent mosquitoes and dust from entering the interior of the garment body 10. Under positive pressure, the gas inside the garment body 10 can also flow through the pressure relief port 103 and push the cover cloth 40 to float up, thereby flowing to the outside of the garment body 10.

[0029] When the connector 20 needs to be cleaned or replaced, the fixing ring 30 is only screwed off from the joint part 22 of the connector 20, and then the connector 20 is taken out from the inside of the garment body 10, thereby compared with the existing positive pressure protective clothing, the connector is fixed by hot pressing or adhesion, and it is difficult to clean and replace, the positive pressure protective clothing provided by the utility model is convenient to assemble and disassemble, and it is beneficial to personnel to clean and replace the connector 20, thereby the service life of the positive pressure protective clothing and the connector 20 can be effectively prolonged.

[0030] Further, as shown in Figure 3 The connector pipe part 23 is combined with the pipe body 90 in a clamping manner, an annular outer flange 231 is protruded on the outer circumferential wall of the connector pipe part 23, and an annular inner flange 91 is protruded on the inner circumferential wall of the pipe body 90, the connector pipe part 23 is inserted into the pipe body 90 and forced, the outer flange 231 can pass through the inner flange 91 through the elastic deformation of the connector pipe part 23 and the pipe body 90, after the elastic recovery of the connector pipe part 23 and the pipe body 90, the outer flange 231 and the inner flange 91 are clamped with each other, so that the connector pipe part 23 and the pipe body 90 are stably combined, thereby personnel can quickly assemble or disassemble the connector pipe part 23 and the pipe body 90, and the operation is convenient.

[0031] Further, as shown in Figure 2 The outer thread 221 of the joint part 22 has a spacing with the base 21, when the fixing ring 30 is screwed with the joint part 22, the part of the garment body 10 at the periphery 102 of the air inlet 101 is less likely to be rolled into the space between the outer thread 221 and the inner thread 31, thereby the periphery 102 of the air inlet 101 is less likely to be damaged, and the air tightness during assembly can be better maintained.

[0032] In addition, as shown in Figure 5 The positive pressure protective clothing can also be provided with a zipper 60, the zipper 60 is arranged on the side of the garment body 10 and extends from the middle of one of the sleeve pipe parts 14 to the end of the lower hem part 13 away from the upper garment part 12, when worn, personnel can also open the zipper 60 and wear the positive pressure protective clothing from the side of the garment body 10, thereby improving the convenience of wearing.

[0033] As shown in Figure 6 The difference between the first preferred embodiment and the second preferred embodiment of the positive pressure protective clothing of the utility model is that the garment body 10A adopts a full-body protective clothing composed of the head cover part 11, the upper garment part 12, the two sleeve pipe parts 14 and the two trouser pipe parts 15, and the air inlet 101 is arranged on the upper garment part 12, and correspondingly, the connector 20 for connecting the pipe body 90 and the fixing ring 30 for fixing the connector 20 are arranged on the upper garment part 12.

[0034] The two leg portions 15 are connected to the bottom end of the upper body portion 12, and each of the leg portions 15 is provided with a band 151 at the leg opening, which cooperates with the band 141 of the sleeve portion 14 to tightly bind the clothing body 10A on the body of a person, and separates the clothing body 10A from the external environment. The air supply device supplies air to form a positive pressure state in the clothing body 10A, which can also prevent harmful gases in the external environment from entering the clothing body 10A, and is suitable for use in situations that require full-body protection.

[0035] As shown in Figure 6 and Figure 7 In the second preferred embodiment of the utility model, the positive pressure protective clothing further comprises a plurality of air outlet buckles 70, each of which is detachably provided on the clothing body 10A and penetrates a plurality of holes 71 for pressure relief. Each of the air outlet buckles 70 penetrates one of the pressure relief openings 103, so that the plurality of holes 71 are connected to the inside and outside of the clothing body 10A. The total cross-sectional area of the plurality of holes 71 is smaller than that of the pressure relief opening 103. By reducing the cross-sectional area of the flow channel, the pressure relief effect can be maintained and the probability of harmful gases in the external environment entering the clothing body 10A can be further reduced. In the second preferred embodiment of the utility model, the plurality of air outlet buckles 70 are respectively located at the head cover portion 11, the positions close to the sleeve openings of the two sleeve portions 14, and the positions close to the leg openings of the two leg portions 15.

[0036] Specifically, each of the air outlet buckles 70 comprises a ring column portion 701 and a stop portion 702 connected thereto. The ring column portion 701 penetrates the pressure relief opening 103, and the stop portion 702 is located outside the clothing body 10A. The outer diameter of the stop portion 702 is greater than the diameter of the pressure relief opening 103. When installed, the ring column portion 701 can be directly penetrated into the pressure relief opening 103 from the outside of the clothing body 10A, and the stop portion 702 can be abutted against the outside of the clothing body 10A. Then, the ring column portion 701 and the clothing body 10A can be fixed.

[0037] As shown in Figure 7 The positive pressure protective clothing comprises a plurality of O-rings 80 for fixing the ring column portion 701 of the plurality of air outlet buckles 70 and the clothing body 10A. Each of the O-rings 80 tightly fits the ring column portion 701 of one of the air outlet buckles 70, so that the part of the clothing body 10A around the pressure relief opening 103 is clamped between the O-ring 80 and the ring column portion 701 of the air outlet buckle 70. In this way, the air outlet buckle 70 can be fixed on the clothing body 10A, and airtight assembly can be formed at the pressure relief opening 103, so that harmful gases in the external environment cannot enter the inside of the clothing body 10A from between the pressure relief opening 103 and the air outlet buckle 70.

[0038] When the air outlet buckle 70 needs to be replaced due to damage, the O-ring 80 can be removed from the air outlet buckle 70 by applying force from the inside of the garment body 10, and then the air outlet buckle 70 can be removed from the outside of the garment body 10, which is convenient and fast. In addition, in the first preferred embodiment or other embodiments, the air outlet buckle 70 and the O-ring 80 can also be used as a pressure relief structure, and are not limited to the second preferred embodiment of the utility model.

[0039] Preferably, as shown in Figure 7 Each air outlet buckle 70 is provided with a ring groove 72 recessed on the outer periphery of the ring column part 701 and located inside the garment body. The O-ring 80 and the peripheral edge 104 of the pressure relief opening 103 are limited in the ring groove 72 of the corresponding air outlet buckle 70. Therefore, when the garment body 10A bends and moves with the movement of the person, the O-ring 80 can be prevented from being separated from the air outlet buckle 70 by the limitation of the ring groove 72, thereby further improving the stability and air tightness after assembly.

[0040] As shown in Figure 8 The third preferred embodiment of the positive pressure protective clothing of the utility model is different from the previous two preferred embodiments in that the garment body 10B is a hood type protective clothing composed of the head cover part 11, the upper garment part 12B, and the two sleeve tube parts 14B, that is, only the head cover part 11, the upper garment part 12B, and the two sleeve tube parts 14B are included, and the air inlet 101 is arranged on the upper garment part 12. Correspondingly, the joint 20 for connecting the tube body 90 and the fixing ring 30 for fixing the joint 20 are arranged on the upper garment part 12.

[0041] The sleeve tube part 14B only extends a small distance from the two sides of the upper garment part 12B to form a sleeve opening for the hand to extend out. The sleeve opening of each sleeve tube part 14B is tightly fastened in a Velcro form to achieve air tightness. The bottom end of the upper garment part 12B directly forms an opening for the person to wear, and is provided with a tightening rope 52 for tightly fastening the bottom end of the upper garment part 12B on the abdomen of the person. In combination with the sleeve opening, the garment body 10B can be tightly fastened on the person's body to separate from the external environment, and filtered air is input through the air supply device to make the inside of the garment body 10B in a positive pressure state, thereby preventing harmful gases in the external environment from entering the inside of the garment body 10B from the bottom end of the upper garment part 12B. For less dangerous occasions, the effect of preventing the person from inhaling harmful gases in the external environment can still be achieved.

[0042] In addition, as shown in Figure 8As shown, in the third preferred embodiment of the present application, each of the sleeve portions 14B has a dividing line extending from the sleeve opening, and the two sides of the dividing line are provided with hook-and-loop fastener 143 to be combined, thereby the user can adjust the combined position of the hook-and-loop fastener 143 according to the thickness of the arm to improve the wearing comfort.

[0043] The above is only the preferred embodiment of the present application, and does not limit the present application in any form. Although the present application has been disclosed as above with the preferred embodiment, it is not intended to limit the present application.
