Problems solved by technology

[0002] Commonly used masks are generally designed with two or three layers of spunbonded non-woven fabric and melt-blown non-woven fabric. This kind of mask can only play the role of dustproof and blocking ordinary virus particles, and its airtightness and barrier effect are very good. Limited, poor protection against highly contagious viruses such as the new coronavirus
In addition, this type of mask completely covers the user's face, and facial expressions cannot be seen during communication with others. In scenarios such as doctor-patient communication, it is easy to increase the patient's nervousness, which is not conducive to the psychological counseling of the patient. Although there are technical personnel A mask made of transparent materials is designed, but due to the continuous generation of water vapor during breathing, it is easy to form atomization on the surface of the transparent mask body, which will still block facial expressions and affect the communication effect
In addition, during the recent diagnosis and treatment of the new coronavirus, it was found that the eyes are also susceptible organs that require special protection. People working and living in epidemic areas not only need to wear high-grade protective masks, but also need to wear goggles, but ordinary goggles also exist. Defects such as easy fogging affect the clarity of vision and bring a lot of inconvenience to users

Embodiment 1

[0027] Such as figure 1 with figure 2 As shown, the transparent respiratory protection device of the present invention includes a fixed belt 11 and a protective mask and a protective goggles connected to each other by a flexible connecting belt 12. The protective mask includes a transparent snout panel 1 and a first sealing ring 2. The sealing ring 2 is fixedly arranged on the mouth and nose panel 1. The first sealing ring 2 closely fits the three-dimensional contours around the mouth and nose of the human face and forms a closed breathing chamber 3 with the mouth and nose panel 1. The chamber 3 is provided with a purifying air inlet 7 and a purifying air outlet 8 on the front side of the open nose. The purifying air inlet 7 and the purifying air outlet 8 are arranged on the nose and mouth panel 1; the protective eye mask includes transparent eyes The panel 4 and the second sealing ring 5, the second sealing ring 5 closely fits the three-dimensional contours around the eyes of ...

Embodiment 2

[0033] Such as Figure 4 As shown, the transparent respiratory protection device of the present invention and image 3 The difference between the technical solutions shown is that the mouth and nose panels and the eye panels are integrated transparent panels 18; in addition, the air supply unit also includes a buffer chamber 21, which is specifically made of flexible material The buffer chamber 21 is connected to the air supply duct 14. On the one hand, the buffer chamber 21 is connected to the air inlet 9 of the glasses chamber 6 through the air supply duct 14 and passes through the second air inlet 9 provided An air intake check valve 19 is in communication with the glasses chamber 6; on the other hand, the buffer chamber 21 is connected to the purification air inlet 7 of the breathing chamber 3 through the air supply duct 14 and is provided through the purification air inlet 7 The second air intake check valve 20 communicates with the breathing chamber.

[0034] Compared with ...

Embodiment 3

[0036] Such as Figure 5 with Image 6 Shows the transparent respiratory protection device of the present invention, and Figure 4 The difference between the technical solutions shown is that the first sealing ring in the protective mask and the second sealing ring in the goggles are made integrally, and the first sealing ring and the second sealing ring include a common intermediate partition 31, which is integrated The periphery of the sealing ring 22 and the intermediate diaphragm 31 fit the three-dimensional contour of the human face. The intermediate diaphragm 31 separates the breathing chamber and the glasses chamber; in addition, the intermediate diaphragm between the breathing chamber 3 and the glasses chamber 6 The air outlet 10 of the glasses chamber 6 is also provided in the middle partition corresponding to the air hole 28. The air purifying protection assembly 27 is provided at the air inlet 9 of the glasses chamber 6, and the air outlet 28 and the glasses chamber T...
