Detailed Description

The technical solution of the present invention will be described in detail with reference to the accompanying drawings, it should be pointed out that the description is only for the purpose of further illustrating the present invention, and the limitation of the protection scope of the present invention is not to be understood, and those skilled in the art can make some non-essential improvements and modifications according to the content of the present invention.

As shown in fig. 1-3, a mask structure capable of alleviating sagging of facial skin and muscle of a person comprises a mask body, wherein the mask body is a disposable mask, an N95 mask, a bowl-shaped plastic mask, A3M mask or other masks, a soft elastic material a1 capable of acting on skin or muscle in a directional manner is arranged on one side of the mask body facing the face of the person, and the acting force can be elastic.

Two ends of the soft elastic material A are respectively fixed on the upper frame 2 of the mask, two ends of one soft elastic material A are not fixed at the same position, and the soft elastic material A does not cross over the nose.

The upper frame 2 of the mask is provided with a soft elastic material A at the left and right sides of the nose.

The soft elastic material A is obliquely arranged, specifically, one end of the soft elastic material A is fixed on the upper frame 2 of the mask, the other end of the soft elastic material A is obliquely fixed on the lower end 3 or the side frame 4 of the mask, and the soft elastic material does not cross over the nose; or the soft elastic material A is vertically arranged: one end of the soft elastic material A is fixed on the upper frame of the mask, and the other end is fixed at the lower end of the mask.

The crossing is provided with a soft friction plate 5 wider than the soft elastic material A.

The middle part of the soft elastic material A which is obliquely arranged can be also connected with another soft elastic material B6, one end of the soft elastic material B is fixedly connected with the middle part of the soft elastic material A which is obliquely arranged, and the other end of the soft elastic material B is fixed at the upper end, the lower end or the side frame of the mask.

The soft elastic material A and the soft elastic material B can be rubber bands.

The rubber band can be elastic coefficient of 10N/m-350N/m, sectional area of 0.25 mm-5 mm, and static friction coefficient of skin and soft elastic material is 0.65-0.85.

The width of the soft elastic material A or B may be 0.5cm to 3cm, but may be wider as required, and is preferably 0.5cm to 1 cm. The maximum width of the soft friction plate can be 0.3 cm-2 cm wider than that of the soft elastic material A or the soft elastic material B.

The technical solution of the present application can be further explained as follows:

by utilizing the nose bridge and the support of the ear band 7/the head band 9 to the upper frame of the mask, the soft elastic material additionally arranged on the inner side of the mask is stretched, and the soft elastic material is pressed and attached to the skin of the face part by utilizing the static friction force f, so that the soft elastic material does not have relative sliding displacement with the pressed and attached face skin, and the elastic force T made of the material is utilized to pull the pressed and attached face skin upwards, and the relaxation and sagging of the face skin and muscles are relieved when people wear the mask. The soft elastic material herein is soft elastic material a and/or soft elastic material B.

For example, when one end of the added soft elastic material is fixed on the upper frame of the mask, the other end of the soft elastic material is fixed at the lower end/lower frame of the mask, namely, at the joint of the lower jaw and the skin, and the soft elastic material does not cross over the nose; when the soft elastic material is stretched downwards by an external force W and then released upwards, the lower frame of the mask is wrapped and limited at the lower jaw when the mask is worn. That is, the soft elastic material is pressed against the skin of the cheek from the top to the bottom. Thereby when the gauze mask was worn at people's face, its elasticity not only can make the gauze mask go up the frame and paste facial skin with lower frame more, guarantee to breathe cleaner air, and the accessible is worn its bottom of drop-down and is laminated the elasticity that makes progress that forms behind the skin when people's face moreover, makes facial part skin lift, slows down the flagging of lax of facial skin and muscle.

Similarly, when one end of the soft elastic material A is fixed on the upper frame provided with the nose bridge plastic strip, the other end of the soft elastic material A is obliquely fixed on the side frame of the mask, and the soft elastic material does not cross over the nose; when the gauze mask was worn at people's face, its elasticity not only can make the gauze mask go up the frame and paste tight facial skin with the lower frame more, guarantees to breathe cleaner air, and the accessible is worn its bottom of drop-down and is laminated the elasticity that makes progress that forms behind the skin when people's face moreover, makes facial part skin lift, slows down the flagging of lax of facial skin and muscle.

Install "a" style of calligraphy soft elastic material additional, soft elastic material's both ends all are fixed on gauze mask upper portion frame, utilize the rigidity of nose bridge molding strip or utilize bowl form to mould the rigidity of type gauze mask edge, keep soft elastic material's "non-effect tensile" state to alleviate the sagging of facial skin and muscle.

Compared with the elasticity of the soft elastic material additionally arranged in the mask, the upper frame of the mask has relative rigidity and takes the nose bridge and the ear belt 7/head belt 9 as supports; the rigidity of the upper frame of the mask is as follows: because of the rigidity of the nose bridge molding strip 8, the rigidity of the edge of the bowl-shaped molding mask or the acting force of pulling back the ear belt/head belt, the force acting on the soft elastic material and acting on the upper frame of the mask through the fixed vertex can always make the deformation of the upper frame far less than the stretching degree of the soft elastic material. That is, under the same magnitude of acting force, the displacement of any point on the soft elastic material is far larger than the deformation displacement of any point on the mask frame. In addition, the upper frame of the whole mask can prolong the arrangement of the nose bridge molding strip, so that the upper frame of the whole mask is provided with the nose bridge molding strip.

For example, the top end of the added soft elastic material is fixed on the upper frame of the mask, the upper frame of the mask has relative rigidity due to the action of the nose bridge molding strip such as an aluminum strip or an aluminum strip, and when the mask is worn on the face of a person, the upper frame of the mask can be maintained on the nose bridge due to the action of the ear strip/head strip and the nose bridge molding strip such as the aluminum strip or the aluminum strip; therefore, the upper frame of the mask can be used as a connecting point of the soft elastic material and also used as a supporting point.

In addition, with the bridge of the nose and the ear straps/head bands as support, we mean: although the skin on the bridge of the nose will be moved downwards by the elastic force T, the bridge of the nose can always be made to act as gravity G supporting the skin fat of the face due to the slope and absolute rigidity of the bridge of the nose; in addition, in the case of using the headband, although the force directions of the headband and the soft elastic material do not completely act on a straight line, it goes without saying that the force component of the headband can also serve to support the gravity G; compared with the ear belt, if the headband is used, the ear belt can avoid the feeling of pain to the ears when the mask is worn for a long time.

The support of the nose bridge and the ear straps/head straps on the upper frame of the mask means that under the condition that the acting force is consistent, the displacement change quantity delta Z of any point Z of the upper frame of the mask in the direction of the elastic force T is far smaller than the displacement change quantity delta X of any point X of the soft elastic material in the direction of the elastic force T. Namely: when the soft elastic material fixed on the top of the upper frame of the mask is subjected to an external force W stretching downwards, the upper frame of the mask can keep relative rigidity no matter the mask is a bowl-shaped plastic mask or a common mask depending on a metal nose bridge strip, and the soft elastic material is obviously stretched downwards.

When the mask is worn on the face of a person, the friction force between the mask and the skin is F' = mu x F by setting the positive pressure F of the soft elastic material pressed and attached to the skin and the friction coefficient mu of the material, so that the soft elastic material with a reasonable friction coefficient mu value can be selected, and the maximum static friction force F is ensured to ensure that no sliding displacement exists between contact surfaces after the skin is pressed and attached to the soft elastic material; and G = m G (m is the sum of the masses of the skin, the fat and the muscle, and G =9.8 cattle/KG) of the gravity of the skin, the subcutaneous fat and the muscle which are pressed and contacted by the soft elastic material. The falling influence of gravity G on the skin and muscles can be eliminated and reduced by stretching the soft elastic material downward and releasing it upward after being attached to the skin so that the upward elastic force T acting on the pressed skin.

Soft elastic materials exist in an "inactive static stretched" state: the soft elastic material, although stretched and pressed against a portion of the skin, does not exert an upward lifting action on the skin and muscles. Therefore, in the "non-operative static stretching" state, it is defined that any point X where the stretched soft elastic material is attached to the skin coincides with point X ' of the skin, and the point Y adjacent to the point X coincides with the point Y ' adjacent to the point X ' of the skin.

When the soft elastic material is in an inactive static stretching state, the bottom end of the soft elastic material is pulled down by an external force W, so that an X point defined by the soft elastic material moves downwards, and the bottom end is released upwards after a Y' point of cheek skin is attached; and (3) keeping the X point and the Y ' point attached without relative sliding displacement by virtue of the friction force f, and simultaneously enabling the soft elastic material to drive the skin to be lifted upwards by virtue of the elasticity T so as to lift the defined skin Y ' point to the original skin X ' point. Namely: when the soft elastic material is pulled down by external force and is attached to local skin of the face, the bottom end of the soft elastic material is limited at the lower jaw of the face in the process of releasing the elastic force upwards, and the upward pulling movement is stopped; and because the friction force f generated by the soft elastic material pressing the skin can keep the two materials from relative sliding displacement, the gravity G which acts on the skin and the fat in the opposite direction by virtue of the elasticity T finally realizes the effects of pressing the soft elastic material against the skin and lifting and keeping the pressed skin. Define when the soft elastic material is in an "applied stretch" state.

After the soft elastic material is transversely stretched, the top end and the bottom end of the soft elastic material are fixed on the upper frame of the mask, and the soft elastic material which is transversely in a straight shape and in an inactive static stretching state has a pressing effect on the skin of the lower eyelid and the cheekbone area by utilizing the rigidity of the upper frame of the mask and the limiting effect of the head band/the ear band on the upper frame. The skin of the lower eyelid and the cheekbone is pulled upwards by external force, and then the lower skin is released downwards, at the moment, the skin of the lower eyelid and the cheekbone is supported by the attached and pressed linear soft elastic material, and the soft elastic material is in an acted and stretched bowstring state in the vertical direction, so that the vertical component plays a role in relieving the relaxation and sagging of the skin and muscles of the attached and pressed lower eyelid and cheekbone area.

In order to make people wear the gauze mask more comfortable, according to different shapes of face and fat thin of size, the utility model discloses the application can be including installing a plurality of width and the different soft elastic material combination of shape difference, coefficient of elasticity and coefficient of friction additional, install like: the soft elastic materials such as X-type, Y-type, H-type, I-type, pi-type and the like can realize more comfortable pressing contact with the facial skin and lifting action on the skin and fat of the facial part; similarly, if the fabric with a large friction coefficient is additionally arranged at the nose bridge, the influence of the elasticity T on the pull-down of the upper frame at the nose bridge can be further reduced, and the support effect of the nose bridge on the mask is ensured. And the width and the thickness of each section of soft elastic material of the X-type, the Y-type, the H-type, the I-type and the Pi-type can be continuously changed, so that the elastic force with different sizes and the acting position interval in the mask can be conveniently set according to the weight of the skin and the muscle of the face to be lifted flexibly.

The straight line type is as follows: one or more soft elastic materials A are respectively arranged on the left side and the right side of the nose on the upper frame of the mask, or are arranged on one side.

The X type is as follows: at least two obliquely arranged soft elastic materials A are arranged on one side of the nose in a crossed mode.

The pi type is as follows: on the frame of gauze mask upper portion, respectively be equipped with one or more soft elastic material A in the left and right sides of nose, perhaps only set up in one side, be equipped with two soft elastic material A below corresponding soft elastic material A, these two soft elastic material A one end are fixed on the frame of the upper portion that is equipped with the aluminium strip, and the other end is fixed on the lower extreme or the lateral part frame of gauze mask to form pi type.

The Y type is as follows: one side of the nose is provided with a soft elastic material A, one end of the soft elastic material A is fixed on the upper frame provided with the aluminum strip, and the other end of the soft elastic material A is fixed on the lower end or the side frame of the mask; and the middle part of the soft elastic material A can be connected with another soft elastic material B, one end of the soft elastic material B is fixedly connected with the middle part of the obliquely arranged soft elastic material A, and the other end of the soft elastic material B is fixed on the upper end, the lower end or the side frame of the mask.

Finally, it is to be noted that:

firstly, description: the aluminum wire and the lower orbit support have rigidity relative to the rubber band.

The soft elastic material can be made of TPE/TPR material which is in accordance with European EN71 standard, does not contain forbidden heavy metals, is safe, environment-friendly, nontoxic and tasteless. The essence of the elasticity of the material is that under the action of external force, the rubber molecular chain is changed from the original curling state to the stretching state, and after the external force is removed, the molecular chain is restored from the stretching state to the curling state. The modulus of elasticity can be expressed by the linear strain as: e = (F/S)/(dL/L), unit: n/m; in the above formula: f is the tensile force, S is the sectional area of the elastic material, L is the original length of the elastic material, and dL is the variable of the stretched length. The modulus of elasticity can also be expressed in terms of volume strain as: k = dP/(-dV/V), unit: megapascals (MPa). The larger the young's modulus, the less likely the material is to deform. In addition, the hooke's theorem is satisfied by known elastic materials: f = kx, where F is the elastic force, x is the tensile length, and k is the elastic coefficient, determined by the young's modulus of the material; the known volume strain of aluminum is 72000MPa, while the volume strain of rubber is 78MPa, which are different by about thousand times. Therefore, the following steps are carried out: under the same acting force, the aluminum wire with the same sectional area is compared with the elastic rubber band, the rubber band is very easy to stretch, the aluminum wire has rigidity property compared with the rubber band, and the aluminum wire is used as a nose bridge strip of the mask, and when the aluminum wire is pressed and attached to the lower eye socket, the aluminum wire can be supported by cheekbones.

II, explanation: data source for coefficient of friction between skin and rubber

Table 12 in section 3.9.2-coefficient of static friction in the thesis of lutianjian and xufeng, university of sienna traffic, approximately represents the coefficient of static friction between facial skin and the tendons, with the average coefficient of static friction of 0.74 for polyurethane (medical rubber gloves) materials with similar properties to skin.

Thirdly, explaining: even with minimal effect, it was further calculated that the elasticity of the band satisfies a certain weight pull-up effect on the face.

Assuming that the sectional area of a common rubber band is 1mm, the elastic coefficient k =200N/m or so, and assuming that the original rubber band is 5cm in length and is elongated by 0.5cm, the tensile force F = kx =200 × 0.005= 1N. Assuming that the weight of the facial fat and muscles to be applied is 50G, the G = mg =0.5N, so that when the elastic band is stretched by 5mm, the elastic force thereof can fully lift the weight of the facial muscles, thereby alleviating the sagging of the facial skin and muscles.

Fourthly, explanation: the elasticity of the rubber band has a pressing and sticking effect on the facial skin.

When the mask is worn, the top end of the soft elastic material is attached to the bottom end of the mandible, and an included angle of about 12 degrees is formed between the top end of the soft elastic material and the straight line segment between the two points at the bottom end of the soft elastic material. Therefore, according to the trigonometric formula, the component of the elastic force perpendicular to the face is the pressure on the skin of the face. Namely, pressure: f ±) 1N sin12 ° = 0.2N. The maximum static friction F = μ × Fn =0.74 × 0.2= 0.15N.

Fifthly, explanation: the static friction force meets the requirement.

From the above calculation, since the maximum static friction force 0.15N is smaller than the face gravity force 0.5N, a sliding displacement occurs. According to the fact that the tension J of the muscle and the minimum action of the rubber band exist as described above, or when the weight of the acted facial fat and muscle is light and is 15G, the gravity G =0.15N, the lifting of the facial skin and the muscle can be achieved. Or increasing the sectional area of the soft elastic material (such as X-type or pi-type using 2 rubber bands).

Sixthly, explanation: since the pressure is very low, the pressure impression on the skin is negligible even when worn for a long time.

The maximum static friction is independent of the area of contact. However, in order to ensure the comfortable feeling of the soft elastic material to the skin and the pressure to the blood vessels of the face, the contact area of the rubber band is enlarged at the cheek to reduce the pressure to the skin of the face. When a soft material with an area of 3cm x 3cm is contacted with the face, the pressure P = F ^ S =0.2/0.0009=289 Pa. The blood pressure of the blood vessels of the human body is usually more than 60 mm Hg, namely more than 8000Pa, so that the soft material pressed on the facial skin can not influence the facial blood vessels. In addition, based on the 'summary of mechanical properties of skin' of Lutianjian and Xufeng of the university of Xian traffic, the 3.2-Young modulus, rigidity and Poisson ratio section in the paper, the Young modulus measured on the skin indentation of the arm of a human body is about 14KPa, therefore, the pressure of about 300Pa is only used, the negative effect on the face skin is not greatly influenced after the skin is worn for a long time, and the indentation which is difficult to eliminate is not generated.

Seventhly, the data of the soft elastic material can be as follows:

setting: the range of the weight of the facial skin fat muscle is as follows: 10 g-50 g; the application is applied to the facial skin, so that the facial skin and fat are lifted upwards by 1 mm-5 mm.

Then: the rubber band with the elastic coefficient of 10N/m-350N/m and the sectional area of 0.25 mm-5 mm is selected; according to different structures (X-shaped, Pi-shaped and I-shaped) of the mask, the length of the unstretched rubber band is 3 cm-12 cm; the linear mask is transversely positioned below the eye sockets and is in a non-acting static stretching state after being fixed, and the unstretched length is 2 cm-4 cm so as to match masks with different sizes; for other X-type/pi-type masks which are longitudinally and obliquely fixed, the top end of the mask is located on the upper frame of the mask, and the bottom end of the mask is located on the lower jaw, so that the unstretched length of the mask is 5 cm-12 cm, and the mask can be matched with masks of different sizes and different models. The static friction coefficient between the skin and the soft elastic material is 0.65-0.85.

The foregoing is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto, and it should be noted that, for those skilled in the art and those familiar with the technical field, the technical solution and the utility model concept of the present invention are equally replaced or changed, and several changes and improvements are made without departing from the overall concept of the present invention, and these should also be regarded as the scope of protection of the present invention.
