Through the fixed pipe 5 of installing at protection hood 1 rear portion and the filter screen frame 10 structure of installing in fixed pipe 5, can make the air that protection measurement personnel breathed when using purer, reduce the possibility that protection measurement personnel infected.
Example two
Referring to fig. 1, fig. 2, fig. 3 and fig. 7, a further improvement is made on the basis of embodiment 1:
the existing protective head hood cannot be adjusted according to the requirements of risks and environments, the protective head hood is not safe enough when used in high-risk areas or under more complex environments, so that protective detection personnel entering the high-risk areas and under more complex environments need to wear other special protective clothing again, wearing of new special clothing and head hoods is completed within ten minutes, and is quite troublesome, one side of the protective head hood 1, which is far away from a face mask 3, is fixedly connected with a connecting pipe 12 at the lower end of a fixed pipe 5, a one-way ventilation mechanism 8 is arranged in the connecting pipe 12, one side of the connecting pipe 12, which is far away from the protective head hood 1, is clamped with a gas pipe 15, a connecting mechanism 7 is arranged on the gas pipe 15, the lower end of the gas pipe 15 is fixedly connected with an air supply device 16, the gas supply device 16 supplies pure air to the protective head hood 1 for the breathing of the protective detection personnel, the protective hood 1 can be worn in an increased or decreased mode according to the complexity of the environment, is suitable for different environments, and is convenient for protective detection personnel to use.
The connecting mechanism 7 comprises an inserting frame 71, the inserting frame 71 is fixedly connected with the air pipe 15, an elastic piece 72 is fixedly connected in the inserting frame 71, one side of the elastic piece 72, which is far away from the inserting frame 71, is fixedly connected with an inserting rod 73, one side of the inserting rod 73, which is close to the connecting pipe 12, is fixedly connected with a clamping rod 74, one end of the clamping rod 74, which is far away from the inserting frame 71 on the same side, is fixedly connected with a clamping block 75, and the clamping block 75 is clamped with the connecting pipe 12.
The inserting rod 73 positioned at the upper end and the lower end of the air conveying pipe 15 is pressed to enable the inserting rod 73 to extrude the elastic piece 72 on the same side to contract, then the air conveying pipe 15 is moved, one end of the air conveying pipe 15 is inserted into the connecting pipe 12, the clamping rod 74 also enters the clamping groove 13, then the inserting rod 73 is loosened to enable the elastic piece 72 to recover, and the clamping rod 74 and the clamping block 75 on one side are clamped in the clamping groove 13 to fix the air conveying pipe 15.
Through the card pole 74 and the fixture block 75 structure that use among the coupling mechanism 7, can be quick be connected with draw-in groove 13 of connecting pipe 12 one side for the gas-supply pipe 15 is connected with connecting pipe 12 fast, shortens the installation of equipment, reduces protection measurement personnel's wearing time, improves the wearing efficiency.
The upper end and the lower end of one side of the connecting pipe 12 close to the gas pipe 15 are provided with clamping grooves 13, and the clamping grooves 13 are clamped with the clamping blocks 75.
The clamping groove 13 matched with the clamping block 75 is arranged, so that the clamping rod 74 and the clamping block 75 can be conveniently clamped with the clamping groove 13, and the air pipe 15 can be conveniently connected with the connecting pipe 12.
One-way ventilation mechanism 8 includes collar 81, collar 81 fixed mounting is in the inside of connecting pipe 12, and collar 81 keeps away from first spring 82 of protection hood 1 one side fixed connection, and first spring 82 keeps away from collar 81 one side fixed connection roof 83, roof 83 and connecting pipe 12 sliding connection set up the logical groove with roof 83 looks adaptation in the connecting pipe 12.
After pure air is conveyed into the connecting pipe 12 by using the air supply device 16 and the air conveying pipe 15, the air extrudes the top plate 83, so that the top plate 83 drives the first spring 82 to contract, the connecting pipe 12 is not blocked by the top plate 83 any more, and the pure air can enter the protective hood 1.
The first spring 82 and the roof 83 structure of setting can play the effect of sheltering from sealing connection pipe 12 when not using the gas-supply pipe 15 to transport the air admission connecting pipe 12, prevent that the direct connecting pipe 12 that sees through of external air from getting into in the protection hood 1, guarantee the closure in the protection hood 1.
EXAMPLE III
Please refer to fig. 1, fig. 2 and fig. 3, a further improvement is made on the basis of embodiment 2:
the length of the air pipe 15 is generally set to be longer than the upper half of the body, but the air transportation is not smooth enough and the use is affected due to the fact that the air pipe is easily bent under extrusion in the using process, the lower end of the protective hood 1 is bonded with the extension sheath 17, the carding mechanism 9 is installed at the lower end of the extension sheath 17, and the carding mechanism 9 is clamped with the air pipe 15.
Carry out spacing fixed to gas-supply pipe 15 through first board semi-ring 92 and second semi-ring 93 that uses in carding mechanism 9 for gas-supply pipe 15 can be fixed, avoids receiving the extrusion condition of buckling to appear.
The carding mechanism 9 comprises a mounting belt 91, the mounting belt 91 is fixedly connected with one side of the lower end of the extension sheath 17, the used mounting belt 91 has plasticity, one side of the mounting belt 91, which is close to the gas pipe 15, is fixedly connected with a first half ring 92, and one side of the first half ring 92, which is far away from the mounting belt 91, is clamped with a second half ring 93.
In order to make the fixing effect of the air pipe 15 better, the upper end of the second half ring 93 is fixedly connected with an auxiliary belt 94, the upper end of the auxiliary belt 94 is fixedly connected with an auxiliary limiting ring 95, and the auxiliary limiting ring 95 is clamped with the air pipe 15.
The auxiliary limiting ring 95 can also limit and fix the upper part of the air conveying pipe 15, so that the air conveying pipe 15 can be better used.
The middle part of the gas pipe 15 is placed in the first half ring 92, the second half ring 93 is inserted into the first half ring 92, the gas pipe 15 is fixed, and meanwhile, the auxiliary limiting ring 95 at the upper end can also limit and protect the gas pipe 15, so that unsmooth gas transmission caused by bending of the gas pipe 15 is avoided.
Example four
Please refer to fig. 1, fig. 2 and fig. 3, which are further improved based on the embodiment 1:
in order to facilitate the air discharge in the protection hood 1, and also can avoid seeing through of outside air to go out in the tuber pipe 14 gets into protection hood 1, stop gear 6 includes extension spring 61, extension spring 61 and homonymy fixed block 141 fixed connection, and extension spring 61 keeps away from fixed block 141 one side fixed connection baffle 62, and baffle 62 shelters from out tuber pipe 14 completely, and baffle 62 is close to the middle part fixed connection stopper 63 in one side of the tuber pipe 14, stopper 63 and the 14 looks adaptations of tuber pipe.
Through the mode that uses extension spring 61 pulling baffle 62, make baffle 62 and stopper 63 can seal out tuber pipe 14 for outside air can't see through out in tuber pipe 14 gets into protection hood 1, and can make the air promote baffle 62. So as to separate the air outlet pipe 14 and discharge the used air out of the protective hood 1.
Air after protection measurement personnel used can push up the stopper 63 of both sides, makes stopper 63 drive baffle 62 and removes to make baffle 62 pulling extension spring 61 extend, and no longer block out tuber pipe 14, make the air can be discharged, when pressure is less, extension spring 61 can drive restoring of baffle 62, makes baffle 62 shelter from out tuber pipe 14, avoids external air to get into in protection hood 1 from going out tuber pipe 14.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
