As shown in fig. 7, a transparent window 12 is arranged on the face of the protective clothing body 1, a mist scraping device 6 is arranged on the transparent window 12, a magnetic sliding groove 62 is arranged on the upper edge and the lower edge of the transparent window 12, a mist scraping strip 61 is arranged on the inner side of the transparent window, magnetic sliding blocks 611 are fixedly connected to the upper end and the lower end of the mist scraping strip 61, the magnetic sliding blocks 611 are slidably arranged in the magnetic sliding groove 62, a magnetic stirring block 63 corresponding to the magnetic sliding block 62 is arranged on the outer side of the lower portion of the transparent window 12, a neck sleeve 3 is arranged on the outer side of the neck of the protective clothing body 1, the bottom of the neck sleeve 3 is fixedly connected with the protective clothing body 1, a neck sleeve sliding block 31 is arranged on the inner side of the top edge of the neck sleeve 3, a neck sleeve groove 13 is arranged on the outer side of the protective clothing body 1 below the transparent window 12, the neck sleeve sliding block 31 is slidably connected with the neck sleeve groove 13, and a connecting strip 631 is arranged on the magnetic stirring block 63 and is connected with the neck sleeve 3 in a clamping manner.
The neck is provided with the neck sleeve, when the neck rotates, the bottom of the neck sleeve is fixed with the protective clothing, the top of the neck sleeve is driven to rotate by a certain angle, the neck sleeve drives the magnetic stirring block to move, the mist scraper in the protective clothing is driven to slide in the magnetic sliding groove, and the mist is scraped on the inner surface of the transparent window to eliminate the influence of water mist. Through setting up the neck cover, need not manual stirring magnetism and dial the piece, only need rotate the neck and just can accomplish and scrape the fog action, liberation both hands when need not scrape the fog, with the connecting strip with the neck cover break away from be connected can.
