Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0033] Embodiment 1

[0034] Reference Figure 1-Figure 7 , an integrated protective suit that can isolate the external environment, including an isolation suit 1, a hood 2 is arranged on the top of the isolation suit 1, the front of the hood 2 is transparent, which is convenient for staff to observe, and a ventilation mechanism 5 for inflating the isolation suit 1 is arranged on one side of the isolation suit 1, and the ventilation mechanism 5 includes a base plate 8, two groups of guide plates 9 are fixedly connected to one side of the base plate 8, and a filter belt 10 is slidably connected between the two groups of guide plates 9, and the filter belt 10 is made of melt-blown cloth and has a filtering effect. Both sides of the base plate 8 are provided with winding components for winding the filter belt 10;

[0035] The winding assembly includes a fixing frame 18, which is fixed to one side of the base plate 8. Two limiting openings 21 are provided on one side of the fixing frame 18. A winding shaft 19 is provided between the limiting openings 21. A through socket 20 is provided on the circumference of the winding shaft 19. The setting of the socket 20 facilitates the insertion of the end of the filter belt 10, thereby facilitating winding. A fixing disk 27 is fixedly connected to the top of the winding shaft 19. The winding shaft 19 on one side is rotated to curl the used filter belt 10 through the winding shaft 19, and the new filter belt 10 is transferred through the other winding shaft 19. To one side of the base plate 8, it is convenient for people to use and avoids the staff from taking off the isolation suit 1 and then changing it. A group of blocks 29 are fixedly connected to the circumference of the fixed disk 27. The top of the fixed frame 18 is rotatably connected to the rotating shaft 30. The circumference of the rotating shaft 30 is fixedly connected to a card plate 31 used in conjunction with the blocks 29. A torsion spring 32 is fixedly connected between the rotating shaft 30 and the fixed frame 18. The fixed disk 27 drives the blocks 29 to rotate. The blocks 29 cooperate with the card plates 31 to avoid reversal of the winding shaft 19, thereby preventing the filter belt 10 from being used again after use.

[0036] The two winding shafts 19 rotate in the same direction. A protective cover 12 is fixedly connected to one side of the base plate 8. The filter belt 10 is located in the protective cover 12. The protective cover 12 can block larger foreign objects.

[0037] Embodiment 2

[0038] Reference Figure 1-Figure 7 , the present invention provides a new technical solution based on the first embodiment:

[0039] In the present invention, slideways 22 are provided at the top and bottom of the fixing frame 18, and limit assemblies for limiting the position of the winding reel 19 are provided in the slideways 22. The limit assemblies include a slider 23 and an insertion rod 25. The slider 23 is slidably connected in the slideway 22, and a limit block 24 for limiting the position of the winding reel 19 is fixedly connected to one side of the slider 23. The insertion rod 25 is fixed to one side of the fixing frame 18, and the insertion rod 25 is plugged into the limit block 24. A spring 26 is fixedly connected between the limit block 24 and the fixing frame 18, and the spring 26 is sleeved on the circumference of the insertion rod 25. The slider 23 is slid, and the slider 23 drives the limit block 24 to break away from the contact with the winding reel 19, so that the winding reel 19 can be conveniently replaced after the filter belt 10 is used.

[0040] In particular, a fan 11 is fixedly installed on the inner wall of one side of the base plate 8, and the air outlet end of the fan 11 is fixedly connected to a flexible connecting pipe 7, and the connecting pipe 7 is fixedly connected to the hood 2. When the fan 11 is started, the fan 11 transports air to the hood 2 through the connecting pipe 7 and then into the isolation suit 1.

[0041] It should be noted that two sets of support frames 15 for supporting the filter belt 10 are fixedly connected to the inner wall of one side of the base plate 8, and an air inlet 17 is provided on one side of the support frame 15. The support frame 15 can support the filter belt 10 to facilitate air filtering.

[0042] In the present invention, an activated carbon net 16 is disposed in each of the support frames 15, and the activated carbon net 16 can further filter the air and improve the air quality.

[0043] In particular, two guide rails 13 are fixedly connected to one side of the protective cover 12, and a battery 14 for supplying power to the fan 11 is slidably connected between the two guide rails 13, so that the fan 11 can continue to work through the battery 14.

[0044] It should be noted that the side of the base plate 8 away from the protective cover 12 is arc-shaped and two shoulder straps 6 are fixedly installed on the top. The arc-shaped setting is convenient for fitting with the back of the human body, and the shoulder straps 6 make it convenient for people to carry the base plate 8.

[0045] In the present invention, air outlet pipes 4 are fixed at the limbs of the isolation suit 1, and the circumferential inner wall of the air outlet pipe 4 is fixedly connected to the intermediate frame 34. A penetrating sliding rod 35 is inserted on one side of the intermediate frame 34, and an air outlet diaphragm 37 is fixedly connected to one end of the sliding rod 35. A tension spring 36 is fixedly connected between the air outlet diaphragm 37 and the intermediate frame 34. Air enters the hood 2 and is then discharged through the air outlet pipes 4 at the limbs of the isolation suit 1. During the discharge process, due to the positive pressure in the isolation suit 1, the air outlet diaphragm 37 is pushed open by pressure, thereby allowing the air to be discharged. When the fan 11 is not started, the air outlet diaphragm 37 is reset under the action of the tension spring 36, thereby preventing air from entering the interior of the isolation suit 1.

[0046] In particular, one side of the isolation suit 1 is provided with a hole for a person to pass through, the hole is connected by a zipper, a sealing sheet 3 is sewn on one side of the hole, the sealing sheet 3 is bonded to the isolation suit 1 by adhesive, and the sealing sheet 3 increases the sealing effect of the isolation suit 1.

[0047] It should be noted that a positioning plate 33 for limiting the position of the clamping plate 31 is fixedly connected to the top of the fixing frame 18 , and the positioning plate 33 prevents the clamping plate 31 from continuing to rotate after the winding shaft 19 is removed.

[0048] Working principle: The staff enters the isolation suit 1 through the perforation on one side of the isolation suit 1, then tightens the zipper and seals the perforation with the sealing sheet 3. During use, the fan 11 is started, and the fan 11 delivers air to the hood 2 through the connecting pipe 7, and then the air is discharged through the air outlet pipes 4 at the limbs of the isolation suit 1. During the discharge process, due to the positive pressure in the isolation suit 1, the pressure is used to push open the air outlet diaphragm 37, thereby allowing the air to be discharged. When the fan 11 is not started, the air outlet diaphragm 37 is reset under the action of the tension spring 36, thereby preventing air from entering the isolation suit 1.

[0049] Before the air enters the isolation suit 1, the larger debris is blocked by the protective cover 12, and then the dust or other foreign matter is filtered by the filter belt 10, and then the air is filtered through the activated carbon net 16 before entering the isolation suit 1, thereby improving the quality of the air in the isolation suit 1;

[0050] When the filter belt 10, which is more prone to clogging or contamination, is contaminated, the winding shaft 19 on one side is rotated to roll up the used filter belt 10 through the winding shaft 19, and the new filter belt 10 is transferred to one side of the base plate 8 through the other winding shaft 19, which is convenient for people to use and avoids the staff from taking off the isolation suit 1 for replacement. When the winding shaft 19 is rotated, it drives the fixed disk 27 to rotate, and the fixed disk 27 drives the clamping block 29 to rotate. The clamping block 29 cooperates with the clamping plate 31 to avoid reversal of the winding shaft 19, thereby avoiding the used filter belt 10 from being used again. When the filter belt 10 needs to be replaced, the slider 23 is slid, and the slider 23 drives the limit block 24 to disengage from the contact with the winding shaft 19, so that the used filter belt 10 is removed, which is convenient for people to replace the new filter belt 10.

[0051] However, as is well known to those skilled in the art, the working principle and wiring method of the fan 11 are commonplace, and are conventional means or common knowledge, and will not be elaborated here. Those skilled in the art may make any optional selections according to their needs or convenience.

[0052] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
