Description

Technical Field

[0001] This utility model relates to the field of protective face shields, and in particular to a protective face shield. Background Technology

[0002] A filter mask is an important piece of personal protective equipment. It's a type of protective face mask primarily used to protect the wearer from harmful substances such as toxic gases, vapors, and particulate matter in the air. It typically consists of the mask body, a filter element, and securing straps. The mask body seals and isolates the wearer from outside air, while the filter element, through built-in adsorbent materials such as activated carbon, effectively filters out toxic and harmful substances, ensuring the wearer breathes safe air. Filter masks are widely used in industry, agriculture, medicine, and scientific research, especially when handling toxic chemicals, performing hazardous operations, or facing air pollution threats, where they provide essential respiratory protection. Traditional filter masks are usually worn over the user's mouth and nose using straps. Because the securing straps on filter masks are simple and typically only serve to secure the mask, their practicality is limited. Therefore, improvements are needed to enhance the practicality of filter masks. Utility Model Content

[0003] The main objective of this invention is to provide a protective face shield that can effectively solve the problems in the background art.

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, a protective face shield includes a protective face shield structure 1. A fixing strap 2 is fixedly installed on the protective face shield structure 1. The fixing strap 2 is composed of a first elastic plate 6, a first soft insulating cotton 7, elastic connecting straps 8, anti-detachment blocking blocks 9, a fixing base block 10, an elastic connecting plate 11, and an anti-detachment baffle 12. The first soft insulating cotton 7 is installed on the inner wall of the first elastic plate 6. Four elastic connecting straps 8 are symmetrically installed at both ends of the first elastic plate 6. Four anti-detachment blocking blocks 9 are respectively installed at one end of each of the four elastic connecting straps 8. The fixing base block 10 has two... Four elastic connecting plates 11 are symmetrically installed on the outer wall of the first elastic plate 6, and are respectively installed at the upper and lower ends of the two fixed base blocks 10. Four anti-detachment baffles 12 are respectively installed at one end of the four elastic connecting plates 11. Two adjustable straps 3 are slidably installed on the four elastic connecting plates 11. The adjustable straps 3 are composed of a second elastic plate 13, a second soft insulation cotton 14, and a connecting block 15. The second soft insulation cotton 14 is installed on the inner wall of the second elastic plate 13, and there are two connecting blocks 15 symmetrically installed on the second elastic plate 13. On the outer wall, the protective mask structure 1 consists of a protective mask body 4, connecting fasteners 5, and a filter assembly 17. Four connecting fasteners 5 are symmetrically fixed to the protective mask body 4. The filter assembly 17 is also installed on the protective mask body 4. In use, the user can wear the protective mask structure 1 over their mouth and nose using the fixing straps 2 and adjustable straps 3. During use, the first soft insulating cotton 7 and the second soft insulating cotton 14 on the fixing straps 2 and adjustable straps 3 can keep the user's head warm; when not in use... When the adjustable strap 3 is in use, it can be folded onto the fixed strap 2. The method is as follows: first, push the second elastic plate 13 and the second soft insulation cotton 14 on the adjustable strap 3 outward, so that the second elastic plate 13, the second soft insulation cotton 14 and the elastic connecting plate 11 bend and deform outward. Then, the adjustable strap 3 can be moved onto the first elastic plate 6 and the first soft insulation cotton 7 on the fixed strap 2, so that the second elastic plate 13 and the second soft insulation cotton 14 are fitted onto the first elastic plate 6 and the first soft insulation cotton 7.

[0020] Ultimately, by setting up the fixed strap 2 and the adjustable strap 3, the filter mask has good cold resistance. This allows the protective mask structure 1 to be fixed to the user's mouth and nose while also providing additional warmth. This makes the user more comfortable when using the filter mask composed of the protective mask structure 1, the fixed strap 2, and the adjustable strap 3 in cold weather, thus improving the practicality of the filter mask. The adjustable strap 3 can be stretched and adjusted, allowing the user to adjust the warmth range according to their needs.

[0021] Furthermore, the elastic connecting strap 8 on the fixing strap 2 passes through the connecting fastener 5. The first elastic plate 6 and the anti-detachment block 9 are located on both sides of the connecting fastener 5. The first elastic plate 6 on the fixing strap 2 is fixedly connected to the first soft insulation cotton 7, the elastic connecting strap 8, and the fixing base block 10. The elastic connecting plate 11 is fixedly connected to the fixing base block 10 and the anti-detachment baffle 12. The elastic connecting strap 8 and the anti-detachment block 9 are fixedly connected. The second elastic plate 13 on the adjustable strap 3 is fixedly connected to the second soft insulation cotton 14 and the connecting block 15. The connecting block 15 on the adjustable strap 3 has a connecting groove 16. The connecting block 15 slides up and down on the elastic connecting plate 11 through the connecting groove 16. When the protective mask structure 1 is worn at the mouth and nose using the fixing strap 2 and the adjustable strap 3, the fixing strap 2 and the protective mask structure 1 can be held in place by the elastic force of the elastic connecting strap 8. The second elastic plate 13 and the second soft insulation cotton 14 are fixed to the user's head and face. They can be slidably mounted on the elastic connecting plate 11 via the connecting block 15. When the adjustable strap 3 is not needed, the second elastic plate 13 and the second soft insulation cotton 14 are pushed outward to cause elastic deformation, thereby disengaging them from the first elastic plate 6 and the first soft insulation cotton 7. Then, the adjustable strap 3 can be slid on the elastic connecting plate 11, so that the adjustable strap 3 is finally fitted onto the first elastic plate 6. At the same time, under the elastic force of the first elastic plate 6 and the elastic connecting plate 11, the adjustable strap 3 can be fixed and will not move easily. When the adjustable strap 3 is needed, it can be pushed directly on the elastic connecting plate 11, so that the second elastic plate 13 and the second soft insulation cotton 14 are positioned above or below the first elastic plate 6 and the first soft insulation cotton 7.
