Abstract
Description
Technical Field
[0001] Exemplary embodiments of this disclosure generally relate to a personal protective equipment (PPE), and more specifically, to a face shield lens for a face mask and a method thereof. Background Technology
[0002] Self-contained breathing apparatus (SCBAs) are essential personal protective equipment (PPE) used in industrial environments to protect workers from inhaling harmful airborne contaminants such as dust, fumes, chemicals, and biohazards. Depending on the required level of protection, SCBAs come in various types, such as half-face or full-face respirators. Full-face respirators offer a higher level of safety by covering the entire face and protecting the eyes, nose, and mouth. However, these respirators have several drawbacks, such as a typically limited field of view (FOV), which can impair a worker's peripheral vision and spatial awareness. Additionally, attaching and maintaining critical components such as the inhalation valve, exhalation valve, and voice diaphragm can be challenging. These components are essential for proper airflow, contamination prevention, and communication, but improper assembly or wear can lead to leaks, reduced protection, or difficulty in speech intelligibility.
[0003] The inventors have discovered numerous defects and problems in the prior art and processes, which are the subject of the embodiments described herein. Through effort, ingenuity, and innovation, many of these defects and problems have been solved by developing solutions included in the embodiments of this disclosure, many examples of which are described in detail herein.

In some embodiments, the surface S3318 of the third aperture 314 may be raised from the front portion 114 of the body 104 relative to the surface S1300. In some embodiments, the surface S3318 of the third aperture 314 may be configured to create a distance gap between the filter or housing 118 and the second portion 108 of the body 104.
[0045] like Figure 5As illustrated, the second portion 108 of the main body 104 can extend from the first portion 106 of the main body 104 at a predetermined angle. The predetermined angle can range from 120 degrees to 140 degrees. In one example, the predetermined angle can include at least three angles: X1, X2, and X3. Furthermore, X1 represents the angle between the first portion 106 and the second portion 108, where X1 is 45.8 degrees. Furthermore, X2 represents the angle at which the second portion 108 extends from the first portion 106, where X2 forms a 44.2-degree angle with the normal. Furthermore, X3 represents the angle between the lower surface of the second portion 108 and the normal, where X3 is 36.6 degrees.
[0046] In some embodiments, a method of constructing a face mask lens 102 for a face mask 100 is disclosed. The method may include one or more operations. In one operation, a first portion 106 of the body 104 of the face mask lens 102 for the face mask 100 may be formed, the first portion 106 forming a predetermined angle with a second portion 108 of the body 104. Furthermore, the body 104 may be configured to be fitted above a user's face. Additionally, the predetermined angle by which the second portion 108 extends from the first portion 106 may be at least 120 degrees and up to 140 degrees. In some embodiments, the first portion 106 may include a top portion of the face mask lens 102, and the second portion 108 may include a bottom portion of the face mask lens 102. In another operation, the body 104 of the face mask lens 102 may also include a first opening 302, which may be formed at the first portion 106 of the body 104. Furthermore, the first opening 302 may be adapted to connect with a voice diaphragm and an inhalation valve. In another operation, a second orifice 304 may be formed below the first orifice 302 of the first portion 106. Furthermore, the second orifice 304 may be configured to connect to an exhalation valve. In another operation, a third orifice 314 may be formed on the side of the second portion 108. Furthermore, the third orifice 314 may be configured to receive a connector assembly 200 that may be configured to connect to the filter or housing 118.
[0047] This invention discloses a face mask lens 102 that combines both comfort and technical performance, thus providing users with an optimal balance between ease of use and functionality. The face mask lens 102 is designed to maximize the field of view, thereby achieving superior peripheral vision and reducing blind spots, which is crucial for a variety of applications such as skiing, motorsports, and tactical operations. Additionally, the optical performance of the face mask lens 102 is enhanced to ensure clear and distortion-free vision under varying lighting conditions. Embodiments of the invention specify that the face mask lens 102 remains firmly in place during dynamic activities, thereby minimizing movement or fogging. This combination of comfort, field of view, optical performance, and product stability ensures a superior user experience in harsh environments.
