[0027] Reference Figure 1-Figure 4 The utility model provides a multifunctional positive pressure air respirator mask: it includes a transparent mask 1, the transparent mask 1 has a wearable strap group, which is convenient for the user to wear, and a mouth and nose mask 2 is fixedly connected to the inner side of the transparent mask. After wearing the transparent mask 1, the mouth and nose mask 2 covers the user's mouth and nose separately, and a cylindrical battery chamber 6 is fixedly connected to the top of the inner side of the transparent mask 1, which plays the role of installing a lighting lamp 9. At the same time, the hollow structure is also used to install a driving power supply. The upper angle of the cylindrical battery chamber 6 is fixedly installed with a lighting lamp 9 for lighting in the lane. The angle-adjustable structural design is convenient for switching between far and near. A driving power supply for powering the lighting lamp 9 is provided in the cylindrical battery chamber 6, and a switch 16 is fixedly installed at one end of the cylindrical battery chamber 6. The switch 16 is used to connect / cut off the driving power supply to power the lighting lamp 9. When in use, the switch 16 is used to control the switch of the lighting lamp 9.

[0028] A vertical threaded column 11 is fixedly installed on the lower side of the cylindrical battery chamber 6, and a threaded sleeve 12 is threadedly connected to the threaded column 11. The bottom of the threaded sleeve 12 is rotatably connected to a bracket 13. A holder 14 is fixedly installed on the end of the bracket 13 away from the threaded sleeve 12, and a lens 15 is fixedly connected to the inner side of the holder 14.

[0029] Due to different users, the height position of the lens 15 needs to be adjusted during use; the threaded sleeve 12 can be rotated to make the threaded sleeve 12 and the threaded column 11 move axially relative to each other, so that the threaded sleeve 12 moves up and down, and then drives the bracket 13 to move up and down to achieve the adjustment of the height position of the lens 15.

[0030] In one embodiment, the strap set includes: a first strap 3, a second strap 4, and a headband 5. The two ends of the first strap 3 and the second strap 4 are respectively fixedly connected to the two sides of the transparent mask 1, and the middle sections of the first strap 3 and the second strap 4 are provided with fasteners for convenient connection. When not worn, Figure 1 As shown in the figure, in order to fit the transparent mask 1 on the face, the buckles of the first strap 3 and the second strap 4 are connected accordingly, one end of the headband 5 is fixedly connected to the top of the transparent mask 1, and the other end of the headband 5 is buckled with the first strap 3 or the second strap 4, so that it can be stably fixed on the user's head.

[0031] In one embodiment, the oronasal mask 2 is equipped with an air inlet with filter cotton and a one-way breathing valve. The filter cotton is used to filter the air entering the oronasal mask 2 through the air inlet, and the one-way breathing valve is a valve body that discharges air outward in one direction.

[0032] In one embodiment, a first connecting ear 7 is fixedly connected to the top of the cylindrical battery chamber 6, a second connecting ear 8 is fixedly connected to the tail of the lighting lamp 9, a fixed shaft 17 is fixedly connected to the second connecting ear 8, and the fixed shaft 17 is rotatably connected to the ear hole of the first connecting ear 7. The first connecting ear 7 has two, and the second connecting ear 8 is located between the two first connecting ears 7. The ear hole of the first connecting ear 7 is threadedly connected to a clamping nail 10 at one end away from the second connecting ear 8.

[0033] Rotate the clamping pin 10 so that the end of the clamping pin 10 presses against the end of the fixed shaft 17, thereby preventing the fixed shaft 17 from rotating. At this time, the lighting lamp 9 cannot adjust its angle and is in a fixed state. When the angle of the lighting lamp 9 needs to be adjusted, loosen the clamping pin 10 to separate its end from the end of the fixed shaft 17, and then the angle of the lighting lamp can be freely adjusted.

[0034] In one embodiment, there are two brackets 13 , which are symmetrically arranged to install two eyeglass lenses 15 .

[0035] In one embodiment, the surface of the cylindrical battery chamber 6 facing the user's forehead is a curved surface that matches the user's forehead. When worn, the curved surface of the cylindrical battery chamber that matches the user's forehead is close to the user's forehead, which brings less pressure to the user and is more comfortable to use.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
