Detailed Description
The technical solution of the present invention will be more clearly and completely explained by the description of the preferred embodiments of the present invention with reference to the accompanying drawings.
Example 1
As shown in fig. 1, the anatomical temperature-controlled nanomaterial protective mask of the present invention comprises a mask body 1 and a hanging strip 2, wherein the hanging strip 2 is connected to the mask body 1 and is used to fix the mask to the head of a wearer. The hanging belt 2 can be hung behind the ears of the wearer and also can be hung on the head of the wearer, and the number and the wearing mode of the hanging belt are not limited in the invention. The breaking strength of the connecting point of each hanging belt 2 and the mask body 1 is not less than 10N.
As shown in fig. 2 and 3, the mask body 1 at least comprises an outer layer 11, an intermediate filter layer 12 and an inner layer 13, wherein at least one of the outer layer 11, the intermediate filter layer 12 and the inner layer 13 is a nanofiber layer.
In this embodiment, the middle filter layer 12 is a nanofiber layer, which is made of nanofiber material, the nanofiber is a linear material with a diameter of nanometer scale and a large length and a certain length-diameter ratio, which is different from the filtration mechanism of the traditional melt-blown cloth material, the traditional disposable medical mask and the N95 mask mainly rely on electrostatic adsorption of melt-blown non-woven fabric as a main filtration means, and the static electricity is gradually lost after contacting with substances such as water, so that the filtration effect is greatly reduced, the two nanofiber materials mainly rely on physical interception, and the filtration stability is higher. The nanofiber layer has a filtration performance of over 95% for small particles having a diameter of 75 nm, and the nanofiber layer is capable of effectively filtering the novel coronavirus due to the fact that the diameter of the novel coronavirus is about 100 nm. In other embodiments, the mask body may further include more layers to enhance the filtration of viruses.
As shown in fig. 2 and 3, the mask body 1 further comprises a temperature-control sealing ring 14, which is arranged on the inner layer 13 and contacts with the face of the human body, wherein the temperature-control sealing ring 14 is made of gel material 14-0. Specifically, the temperature-control sealing ring 14 comprises a coating layer 14-1, and a gel material 14-0 is filled in the coating layer 14-1. The coating layer 14-1 is fixed with the mask body 1 by ultrasonic welding, thereby forming the mask with an integrated structure. As shown in FIG. 4, the coating layer 14-1 is filled with a gel material and then is formed into a bulge shape, the cross section of which is an arch shape, and the height of the arch shape is 2 to 8 mm. This design provides a degree of flexibility to the temperature controlled closure ring 14,
in this embodiment, the gel material 14-0 is hydrogel, preferably a high molecular skin-friendly hydrogel. The hydrogel comprises water, mint and silver ions, wherein the content of the silver ions is 0.0001-0.05%, the hydrogel is a very hydrophilic three-dimensional network structure gel, a large amount of body surface heat can be adsorbed by utilizing the characteristic of high specific heat capacity of water in the hydrogel, and the absorbed heat can be quickly dissipated into the air by utilizing the good heat conduction performance of three-dimensional network molecules in the gel, so that when a medical worker wears the mask, the temperature and the humidity of the position where the face is in contact with the mask are appropriate, the hydrogel is soft in texture and free of skin irritation, and the problem that the impression is easy to occur when the traditional mask is in contact with the skin for a long time can be solved.
In addition, the coating layer 14-1 is filled with gel material 14-0, and a ring of protrusions are formed on the inner layer 13, so that the temperature-control sealing ring 14 has certain elasticity. When the mask is worn on the face of a human body, the temperature control sealing ring 14 is in contact with the face, the temperature control sealing ring 14 is tightly pressed with the face under the tightening action of the hanging belt 2, and the temperature control sealing ring 14 has elasticity, so that the temperature control sealing ring 14 can deform according to the outline of the face, the temperature control sealing ring 14 is well attached to the face, and the sealing property of the mask is improved. In addition, the design also enables the temperature control sealing ring 14 to be well adapted to different facial contours and has a self-adaptive function, so that the problems that gaps exist when the existing mask cannot be adapted to different facial contours, and viruses still enter nasal cavities and oral cavities when the mask is worn are solved.
Considering that the nose of a human body protrudes out of the face, in order to ensure the leakproofness of the mask and the nose bridge, the existing masks mostly adopt galvanized iron wires as plastic nose bridge strips for being matched with the nose bridge. The galvanized iron wire has deformability, but does not have elasticity, so that after a wearer presses the nose bridge strip, the wearer always keeps the pressed shape, presses the nose bridge part and is in hard contact with the nose bridge part, and the face and face of the medical staff are oppressively damaged after wearing the nose bridge strip for a long time; in addition, this galvanized iron wire can not take place deformation along with facial action, and after the action of the face or the head took place for the wearer, the bridge of the nose strip just probably does not laminate with bridge of the nose department, produces the space, and does not play the guard action.
In order to solve the problem of tightness of the nose bridge part, the mask disclosed by the invention is designed in an anatomical mode. Specifically, the temperature control sealing ring of the mask adopts a split type design at the nose bridge, rather than the whole sealing ring adopting the same thickness.
As shown in fig. 2, is an embodiment of a cut-away design of the temperature controlled sealing ring 14. The temperature control sealing ring 14 adopts a concave design 14-2 at the contact part with the nose bridge of the human body so as to be matched with the contour of the nose bridge of the human body, ensure the nose bridge to be fully contacted with the mask and improve the sealing performance of the mask.
Fig. 3 shows another embodiment of a cut-away design of the temperature controlled sealing ring 14. The temperature control sealing ring 14 adopts a disconnection design 14-3 at the contact part of the nose bridge of the human body, a space is reserved at the nose bridge, and the sealing at the nose bridge is realized by depending on the outline of the mask body 1.
Example 2
As shown in figure 5, as a technical optimization of the invention, the gel material 14-0 of the temperature-controlled sealing ring 14 is directly combined with the inner layer 13 of the mask without a coating layer. The gel material 14-0 is preferably a hydrophilic polymer gel material.
Because the hydrophilic gel material of macromolecule does not have the stimulation to skin temperature, so the hydrophilic gel material of macromolecule can with skin direct contact, and utilize the good adhesion effect of the hydrophilic gel of macromolecule to closely laminate the sealed circle 14 of accuse temperature in the face of wearing person, prevent to appear the gap between the sealed circle 14 of accuse temperature and the face of wearing person, reduced the risk of infecting novel coronavirus.
In this embodiment, the gel material 14-0 is in direct contact with the face, and the cooling and moisturizing effects are better.
The above detailed description merely describes preferred embodiments of the present invention and does not limit the scope of the invention. Without departing from the spirit and scope of the present invention, it should be understood that various changes, substitutions and alterations can be made herein by those skilled in the art without departing from the spirit and scope of the invention as defined by the appended claims and their equivalents. The scope of the invention is defined by the claims.
