Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments.

Example 1

Referring to fig. 1-4, a filtering face mask comprises a face mask 1, goggles 2 and a filter 3 are arranged on the front side of the face mask 1, the filter 3 plays a role in filtering incoming gas, a binding band 4 is arranged on the rear side of the face mask 1, at least two binding bands 4 are arranged on the filtering face mask through the elastic binding bands 4, and at least two binding bands 4 are adopted, so that one of the binding bands is sleeved on the neck, the other binding band is sleeved on the head, the fixing effect on the filtering face mask is enhanced, and falling situations are prevented.

The rear side of the face mask 1 is provided with a silica gel layer, and the design of the silica gel layer is adopted, so that the comfort of the face mask 1 in contact with the skin is improved.

The goggles 2 are provided with the movable blocks 8 through the moving mechanism, the movable plates 6 are connected to the movable blocks 8, the limiting frames 10 are fixedly connected to the movable plates 6, the cleaning blocks 9 are placed in the limiting frames 10 and are in butt joint with the goggles 2, the cleaning blocks 9 comprise sponge blocks and cotton cloth, the cotton cloth is arranged on the outer sides of the sponge blocks, the movable blocks 8 are driven to move through the moving mechanism, the cleaning blocks 9 move, the cleaning blocks 10 wipe water mist on the inner sides of the goggles 2, the goggles 2 are ensured to be clear, interference to doing experiments is avoided, and the cleaning blocks 9 are made of cotton cloth materials and have good hygroscopicity, so that the water mist is favorably wiped clean when the goggles 2 are contacted.

The moving mechanism comprises a threaded rod 7, the threaded rod 7 is arranged at the upper end of the goggles 2, shielding is not caused by a video line, threads of the threaded rod 7 penetrate through a moving block 8, the moving block 8 is in butt joint with the goggles 2, the threaded rod 7 is rotatably connected with the goggles 2 through a sealing bearing, the sealing of the inner space of a face mask is guaranteed, the goggles 2 are extended from two ends of the threaded rod 7, the position of the moving block 8 on the goggles 2 is adjusted by rotating the threaded rod 7, the moving block 8 is not moved due to the butt joint of the moving block 8 and the goggles, the moving block 8 can be made of rubber materials, so that scratch is prevented from being caused to the goggles 2 during movement, and after the moving block 8 is moved to one end of the goggles 2, as shown in fig. 2, shielding is prevented from being caused to the vision line.
