Description

Plane mask

Technical Field

The utility model relates to a gauze mask technical field, concretely relates to plane gauze mask.

Background

In recent epidemic situations, the amount of mask used has increased dramatically, but there are still certain problems in the effect and convenience of use.

The inventor and family find that the three-dimensional mask with good protection effect has large oppression on the face when being worn for a long time, has high cost and is not easy to buy. The disposable medical surgical mask with larger usage amount has higher use comfort and convenience, and is convenient to manufacture, lower in cost and easy to purchase. However, the planar mask is difficult to completely keep the fit with the face when in use, and mainly has two aspects, namely, a gap is easy to remain at the nose bridge part and air leaks upwards; the upper ear belt and the lower ear belt are connected on the left side and the right side of the mask, so that the mask can be kept in a better fit state with the face, and the middle part between the upper ear belt and the lower ear belt is easy to deform and warp outwards, so that a larger gap is left. The space of above-mentioned two positions exists, causes very big influence to the protective effect of ear muff, and the droplet of air current and specific angle etc. all can be from this clearance in the inlet cover inside to lose protective effect. Even if the mask is not used as a tool for preventing viruses and germs, the mask is used as scenes such as dust particles, haze prevention, warm keeping, wind shielding and the like, and the use effect can be seriously influenced by the gap between the mask and the face.

In the case where the wearer carefully adjusts the wearing of the mask, for example, the nose bridge strip may be brought into full contact with the upper portion and the peripheral area of the nose of the wearer, and the left and right sides of the mask may be pulled and flattened to be fully contacted with the face, thereby largely eliminating the adverse effect of the gap. However, such adjustments may be appreciated and mastered by the medical professionals, but for the general users, the degree of emphasis and mastered is limited, and the adjustments are generally not in place, leaving a risk potential. This adjustment arrangement is also less efficient and time consuming for most people, including medical personnel. Even if the mask is adjusted to be in place to be completely attached to the face of a human body, the user inevitably acts for a long time, and facial muscle action occurs, thereby destroying the attachment.

The elastic strip 6 is a flat-shaped elastic strip. Through the design of the flat structure of the elastic strip 6 and the embedded matching with the nose bridge clip 5, the inner layer of the mask can be guaranteed to keep a roughly planar state, the protrusion of the inner surface cannot be generated, the comfort of a user is guaranteed, meanwhile, the laminating performance of the mask and the face is also enhanced, and the air tightness performance is guaranteed.

In this embodiment, the elastic strip 6 is disposed on the surface of the nose bridge clip 5 facing the face of the user in a fitting manner. Through with the laminating setting of elasticity strip 6 on the bridge of the nose presss from both sides 5 towards the facial surface of user, can press from both sides 5 with the bridge of the nose with elasticity strip 6 and bridge of the nose and make together in advance, sew up into the gauze mask body as an organic whole structure during gauze mask production to reduce the transformation to preparation technology and equipment, the make full use of current equipment and technology of being convenient for.

The two ends of the elastic strip 6 in the length direction are respectively provided with a smooth transition section 60. Through setting up smooth transition section, can prevent to form comparatively obvious elastic layer and break off to guarantee all make gauze mask inlayer and facial laminating completely on the length direction of whole bridge of the nose clip 5 and other parts of neighbouring gauze mask.

The smooth transition section 60 is obliquely arranged relative to the surface of the nose bridge clip 6, and the thickness of the smooth transition section 60 is gradually reduced towards the two ends of the elastic strip 6 along the length direction. This is a simpler smooth transition setting method.

The length of the elastic strip 6 is equal to or less than the length of the nose bridge clip 5.

The nose bridge clip 5 comprises a plastic surround 51 and a metal strip 52 disposed within the plastic surround 51.

The utility model discloses an elasticity strip is arranged in plane gauze mask, has obvious advantage. In addition, the structure of the utility model is beneficial to manufacturing, can separate the manufacturing process, and attaches the elastic strip on the nose bridge clip in advance when manufacturing the nose bridge clip. Generally speaking, the elastic strip with the structure can be arranged in a thicker size so as to have larger elasticity, and the inner layer of the mask or the sealing strip arranged on the inner layer of the mask is driven to be attached to the nose and the nearby part of a user.

According to the utility model discloses gauze mask, the laminating of elasticity strip and other parts can be taken sticky, hot pressing or refer to other suitable technologies and laminate and be connected.

The mask body in this embodiment is used as the structural foundation of the mask body in embodiments 3 to 9, and the elastic strip attached to the nose bridge clip in this embodiment can be used in combination with the technical solutions of embodiments 3 to 9.

Example 2

As shown in fig. 1, 3 and 4, the present embodiment is different from embodiment 1 mainly in that, in the present embodiment, the elastic strip 6 is attached to the surface of the mask body 1 opposite to the surface of the nose bridge 5 facing the face of the user. The elastic strip 6 is attached to the surface of the mask body 1 opposite to the surface, facing the face of a user, of the nose bridge clip 5, a process for attaching the elastic strip to the mask body can be added to existing processes and equipment under the condition, the process is simple and convenient, and the existing equipment and the process are convenient to reform.

Example 3

As shown in fig. 5, a flat mask comprises a mask body 1 and ear straps 2 connected to the left and right sides of the mask body 1, wherein the mask body 1 comprises an inner layer 11, a middle layer 12 and an outer layer 13; still be equipped with connecting portion 3 between gauze mask body 1 and the ear area 2, one side of connecting portion 3 with be connected through three more than first connecting portion 31 between the side of gauze mask body 1, the opposite side of connecting portion 3 is connected through second connecting portion 32 respectively with two tip of the ear area 2 of place side. The deformation and the air tightness of the plane mask in the left side and the right side of the plane mask in the prior art mainly result from the structure of the plane mask. Since the ear band is worn on the ear of the user, it is the most feasible method to select the two-point coupling structure, which would otherwise cause serious inconvenience in use. However, the two points of the ear belt and the mask body are connected, so that the middle parts of the two sides of the mask are not stressed enough, and the problems of deformation, warping and the like are very easy to occur. The utility model discloses based on this point, add connecting portion, and guarantee connecting portion and gauze mask body have three more than three connection position for example three connection position or five connection position, so when receiving the pulling force that the ear zone transmitted, connecting portion pass through multiple spot pulling gauze mask both sides edge, under the condition of multiple spot atress, have guaranteed that gauze mask both sides atress is comparatively balanced, and near apart between the stress point to ensure that the gauze mask left and right sides is laminated in user's face more closely, and the user realizes that the laminating effect is more convenient more swift. On the other hand, the connecting part and the ear belt still keep a two-point connecting structure similar to the traditional ear belt connection, thereby ensuring the normal and convenient use of the ear belt.

The second connecting portions 32 are respectively located at upper and lower positions of the mask body 1. The normal and convenient use of the ear belt is ensured.
