[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "all around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0027] like Figure 1-5 As shown, a medical protective mask comprises: a cover shell 2, a fixing ring 1, goggles 9, a hinged portion and a mask 10; the goggles 9 are fixedly mounted on the cover shell 2, and the hinged portion is arranged between the fixing ring 1 and the upper side of the cover shell 2; the hinged portion comprises a fixing block 3, a mounting plate 5, a hinged head 6 and a first bolt 4, the fixing block is fixedly mounted on the fixing ring 1, a bayonet is fixedly connected to the fixing block 3, a plurality of slots 13 are provided in the length direction of the mounting plate 5, and the bayonet is selectively Cooperating with the multiple slots 13, the first bolt 4 penetrates into the mounting plate 5 and is threadedly connected to the mounting plate 5; the first bolt 4 passes through the multiple slots 13 in sequence and is threadedly connected to the bayonet pins in the slots 13; the hinge head 6 is fixedly mounted on the mounting plate 5 and is hinged to the cover shell 2; the mask 10 is arranged below the goggles 9, and a plurality of adjustment blocks 8 are provided between the mask 10 and the cover shell 2, and the outer wall of the mask 10 is detachably connected to the adjustment block 8.

[0028] The following further describes the use principle of the present invention. When in use, the medical staff can put the fixing ring 1 on the head, and then rotate the cover 2 along the hinge 6 so that the cover 2 covers the face. At this time, if the height position of the goggles 9 is not suitable and is not aligned with the wearer's eyes, the first bolt 4 can be rotated again to make the first bolt 4 and the bayonet in the slot 13 disengage, so that the mounting plate 5 is separated from the fixing block 3, and then the bayonet is engaged with the appropriate slot 13, so that the goggles 9 are aligned with the wearer's eyes, and then the first bolt 4 is tightened to fix the mounting plate 5 and the fixing block 3 together.

[0029] Through the above arrangement, the protective ability of the entire medical protective cover can be improved through the protection of the cover shell 2, the goggles 9 and the mask 10, and the eyes, mouth and nasal cavity of the wearer can be effectively protected. Then, by adjusting the position between the mounting plate 5 and the fixing plate, the goggles 9 can be aligned with the eyes of the wearer, and can be adapted to wearers with different eye positions.

[0030] Furthermore, the mask 10 is made of non-woven fabric.

[0031] Furthermore, the adjustment block 8 includes a base plate 11, a spring, a second bolt 7 and a rotating plate 12; the base plate 11 is attached to the cover shell 2, and the rotating plate 12 is hinged to the base plate 11 in a V-shaped arrangement; the second bolt 7 penetrates between the base plate 11 and the rotating plate 12 through the V-shaped opening and rests on the inner wall of the rotating plate 12; the second bolt 7 is threadedly connected to the base plate 11; the two ends of the spring are fixedly connected to the base plate 11 and the rotating plate 12 respectively; the outer wall of the mask 10 is detachably fixed to the end face of the rotating plate 12 away from the base plate 11.

[0032] With the above arrangement, when the wearer's face fits too tightly against the mask 10, it is easy to crush the patient's face if worn for a long time. At this time, the second bolt 7 should be rotated to reduce the angle between the base plate 11 and the rotating plate 12, and the outer end of the rotating plate 12 drives the mask 10 away from the wearer's face, thereby effectively avoiding crushing the wearer's face. When the wearer's face fits too loosely against the mask 10, a large gap is formed, and the protective effect is deteriorated. At this time, the second bolt 7 should be rotated in the opposite direction, so that the mask 10 fits tightly against the wearer's face, and a gap is not easily formed, thereby effectively enhancing the protective effect.

[0033] Furthermore, a first Velcro is fixedly installed on the end surface of the rotating plate 12 away from the base plate 11, and a second Velcro is fixedly installed on the outer wall of the mask 10. The second Velcro is attached to the first Velcro, so that the wearer can easily replace the mask 10.

[0034] Furthermore, a rubber pad is provided on the inner wall of the goggles 9 to prevent the wearer's face from being crushed by wearing the goggles for a long time.

[0035] Furthermore, a disposable protective pad is detachably fixedly mounted on the inner wall of the fixing ring 1, which is more convenient for replacement and prevents the fixing ring 1 from being contaminated.

[0036] Furthermore, the substrate 11 is adsorbed on the cover shell 2 by a suction cup, and when the mask 10 is not needed, the substrate 11 can be removed so that the wearer can obtain a wider field of vision.
