Description

Technical Field

[0001] The utility model relates to the field of pollution protection masks, in particular to a novel anti-pressure injury and indentation protection mask. Background Art

[0002] Masks and goggles are very common in our daily lives. They are mainly used to protect the mouth, nose and eyes of people. They can prevent toxic gases, dust, bacteria, toxic and harmful gases or steam and other toxic substances from causing harm to the human body. They are widely used in chemical industry, firefighting, disaster relief, health and epidemic prevention and other fields, all of which require goggles and masks. Currently, goggles and masks on the market are mostly two independent products. Users need to wear and fix them twice, which is time-consuming, laborious and uncomfortable. At the same time, gaps are very likely to appear between the mask and the face or bridge of the nose, resulting in reduced fit, causing the air exhaled from the nasal cavity to form mist on the lens, affecting vision. Although the existing protective masks integrate the functions of eye masks and masks, and are faster to wear than wearing separate masks and eye masks, the protective masks are mostly made of hard materials in the overall design, and the face is only linearly fitted with the edge of the protective mask, resulting in poor fit and poor comfort. In addition, in order to replace the protective filter element, a filter element accommodating structure is usually provided on the protective mask. When replacing the filter element, the cover needs to be disassembled. Therefore, the overall design structure has the disadvantages of being large in size, bulky and complex in structure, resulting in the problems that the protective mask is not convenient for cleaning or replacing the mask, is not convenient for carrying and is costly.

[0003] For example, a protective mask with application number CN202210085711.8 (publication (announcement) number: CN114377313A) includes an eye mask, an oral-nasal mask and a strap group, and upper and lower fixing parts for fixing the strap group are respectively provided on both sides of the rear end of the eye mask and the rear end of the oral-nasal mask, and the eye mask, the oral-nasal mask, the upper and lower fixing parts are integrally formed with elastic material, and a slot for placing a lens is provided on the eye mask; a breathable area is provided at the front end of the oral-nasal mask, and an elastic sealing surface for fitting with the face is provided on the edge of the rear end of the oral-nasal mask, which is bent and extended inward, and a clamping groove for fixing the filter element material is formed with the elastic sealing surface and the edge of the rear end of the oral-nasal mask; the invention has a high degree of fit with the face, the filter element material can be quickly disassembled and assembled, it can be folded and carried, the overall structure is simple and comfortable, it can be washed and reused, and is suitable for a variety of scenarios, especially in emergency applications such as fire escape and epidemic prevention. It is more valuable and has the advantages of high assembly efficiency, high fit and easy to carry.

[0004] The above protective masks are "the upper fixed part and the lower fixed part, the eye mask part, the mouth and nose mask part, the upper fixed part and the lower fixed part are formed in one piece with elastic materials", which makes it impossible to take off the glasses when in use, and it cannot be used flexibly. Sometimes it is necessary to remove the eye mask or the mask part, or the breathing gas will cover the eye mask part, resulting in unclear vision. The one-piece structure of the mask makes the eye mask part unable to move, and it cannot be adjusted during use, resulting in temporary loss of vision. In addition, since the current masks completely close the mouth, nose, and eyes, they are tightly pressed against the face after being put on. After being worn for a long time, indentations will appear on various parts of the face, and repeated long-term wearing can easily cause pressure sores. Summary of the invention

[0005] In order to solve the above technical problems, the purpose of the utility model is to provide a new type of anti-pressure and indentation protective mask.

[0006] In order to achieve the above purpose, the technical solution of the utility model is as follows:

[0007] A novel anti-pressure and indentation protective mask comprises an eye mask portion, a face mask portion and a strap group, wherein both sides of the rear end of the eye mask portion and both sides of the rear end of the face mask portion are respectively provided with an upper fixing portion and a lower fixing portion for fixing the strap group, the eye mask portion is separately connected to the face mask portion, both sides of the upper end of the eye mask portion are rotatably connected to the face mask portion, female buckles are provided on the left and right sides of the nose bridge portion of the face mask portion, male buckles clamped on the female buckles are provided on the left and right sides of the lower end of the eye mask portion, a circle of sealing strips is fixed on the edge of the eye mask portion and the edge of the face mask portion, and a layer of non-woven fabric is fixed on the surface of the sealing strips.

[0008] Furthermore, rotation holes are provided on both sides of the upper end of the eye mask portion, and rotation pins are provided on both sides of the upper end of the face mask portion, and the rotation pins are inserted into the rotation holes.

[0009] Furthermore, the eye mask portion is rotated upwards at an angle greater than 90° relative to the face mask portion.

[0010] Furthermore, ventilation valves with covers are provided on the left and right sides of the lower end of the mask part.

[0011] Furthermore, there are two groups of strap groups, both of which are Y-shaped, with the front ends thereof being respectively connected to the upper fixing part and the lower fixing part, and the rear ends of the two groups of strap groups being detachably connected together.

[0012] Furthermore, a mask hook is provided at the V-shaped gap of the strap assembly, and the mask hook faces the side away from the head.

[0013] Furthermore, a layer of hydrogel pad is fixed on one side of the strap assembly that fits the face or head.

[0014] The above design has the following advantages over the prior art: since different components can be used separately or in combination, the split protective mask provides more flexibility to adapt to different working environments and protection needs. The wearer can adjust whether to wear the mask at will, which helps to reduce moisture and heat accumulation inside the mask and improve the wearer's comfort. The split mask can add additional protective components as needed, such as anti-fog coating, UV-proof lenses, etc., to provide more comprehensive protection.

[0015] In addition, all parts of the mask, eye mask and strap group that come into contact with the human body are designed with silicone material. First, it can ensure airtightness, especially for medical staff who wear it in an environment prone to infection. Second, silicone or medical hydrogel material can prevent facial compression when worn for a long time, avoiding indentations and more serious pressure sores. BRIEF DESCRIPTION OF THE DRAWINGS
