Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

For clarity of description and understanding of this patent, other tooling structures and equipment part structures that can be used in addition to the tooling designed for this patent are shown in the figures.

Example one

Please refer to fig. 1, a mask, which comprises a mask body 1 and a tying belt 2,

bilateral symmetry sets up frenulum 2 sets up respectively the left and right sides of the preceding terminal surface of the cover body 1, frenulum 2 includes hangers rope 21 and connects rope 22, many connect rope 22 and connect respectively the both ends of hangers rope 21, connect rope 22 not with the one end of hangers rope 21 contact with the cover body 1 is connected fixedly, is located the same one end of hangers rope 21 the quantity of connecting rope 22 is two at least.

Specifically, when using, the hangers rope 21 is taut respectively to many connecting rope 22, and the connecting rope 22 quantity that each end of hangers rope 21 is connected is two at least, when wherein certain connecting rope 22 fracture or became invalid, remaining connecting rope 22 still can be with hangers rope 21 tensioning to take up gauze mask body 1.

It should be noted that the connection points between the plurality of connection ropes 22 located at the same end of the ear hanging rope 21 and the cover body 1 are not limited to the same point.

It should also be noted that the present invention is particularly suitable for use with N95 masks.

Example two

Further improvements are made on the basis of the first embodiment.

Please refer to fig. 1, fig. 5, fig. 6, and further includes a soft support 3, wherein the soft support 3 is disposed at the connection position of the hanging rope 21 and the connecting rope 22.

Compared with a common mask, due to the fact that the number of the connecting ropes 22 is increased, pressure on the face of a human body is dispersed, more tightening marks can be caused after the mask is worn for a long time, the connecting ropes 22 and the ear hanging ropes 21 are supported through the soft supports 3, and the contact area between the lace 2 and the face of the human body is reduced.

In the process of wearing the mask (especially the N95 mask), due to long time, the mask tying belt 2 tightly presses the auricle skin to easily generate pressure injury, and the soft support 3 (the soft support is made of elastic skin-friendly materials such as silica gel) is used for dispersing the pressure of the contact part of the tying belt 2 and the skin to the skin, so that the pressure injury is reduced.

As a further alternative, the front end surface of the soft holder 3 is provided with mounting grooves 31, the mounting grooves 31 penetrate through the left and right ends of the soft holder 3, and the ear hanging ropes 21 and the connecting ropes 22 can be mounted through the mounting grooves 31.

Obviously, the purpose of forming the mounting groove 31 is to achieve the recycling of the soft support 3, and the soft support 3 integrally formed on the outer wall of the connecting rope 22 and the hanging lug rope 21 should also belong to the protection scope of the present invention.

As a further alternative, the upper and lower walls of the installation groove 31 are provided with a first limiting member 311 protruding towards the middle, the first limiting member 311 limits the ear hanging rope 21 and the connecting rope 22 entering the installation groove 31, the shape of the first limiting member 311 is preferably a right triangle, and after the tying belt 2 enters the installation groove 31, the tying belt 2 is limited from sliding out of the installation groove 31 by the right triangle.

As a further alternative, the second limiting member 312 is disposed on the rear wall of the mounting groove 31, the second limiting member 312 is located between the plurality of connecting ropes 22, and the second limiting member 312 is used to separate the plurality of connecting ropes 22, so that the connecting ropes 22 can be better limited in the mounting groove 31.

It should be noted that the number of the second stoppers 312 is not limited to one, the number of the second stoppers 312 = the number of the connecting ropes 22 — 1, and when the number of the connecting ropes 22 is greater than two, the first stoppers 311 should be disposed on the side wall between two adjacent second stoppers 312 to limit the positions of the connecting ropes 22.

EXAMPLE III

Please refer to fig. 2, fig. 3, and fig. 4, which are another improvement based on the first embodiment.

Still include

sheath

4, 4 demountable installation of sheath are at the outer wall of hangers rope 21, through setting up sheath 4, can increase the area of contact of hangers rope 21 and ear, reduce or reduce the emergence of pressure nature damage, improve and wear the comfort level.

Example four

The structure of the sheath 4 will be specifically described.

Please refer to fig. 2, the sheath 4 is a strip and is spirally wound on the outer wall of the hanging rope 21, when in use, the spiral sheath 4 is stretched into a strip, and then the sheath 4 is spirally wound on the outer wall of the hanging rope 21.

It is clear that the sheath 4 should be made of a soft material, such as silicone.

EXAMPLE five

The structure of the sheath 4 will be specifically explained.

The difference from the fourth embodiment is that.

Please refer to fig. 3 and 4, the sheath 4 is a tubular structure, the sheath 4 is provided with a through slot 41 penetrating through the inner and outer walls of the sheath 4, and the through slot 41 penetrates through two ends of the sheath 4.

When in use, the hangers 21 are arranged in the inner cavity of the sheath 4 along the through groove 41.

As a further alternative, a closure structure 42 is provided, the closure structure 42 being capable of restraining the lanyard 21 within the sheath 4.

As a further alternative, a specific structure of the sealing structure 42 will be explained.

Sealing structure 42 includes first connecting plate 421 and second connecting plate 422, and first connecting plate 421 and second connecting plate 422 all set up the outer wall at sheath 4, and first connecting plate 421 and second connecting plate 422 are located the both sides that run through groove 41 respectively, and first connecting plate 421 and second connecting plate 422 will run through groove 41 and seal through pasting closely each other.

Due to the arrangement of the first connecting plate 421 and the second connecting plate 422, when the sheath is worn, the positions of the sheath 4 can be limited by the first connecting plate 421 and the second connecting plate 422, and the penetrating groove 41 is guaranteed not to rotate to the joint with the skin.

The connection mode of the first connection plate 421 and the second connection plate 422 can be magnetic attraction, clamping, bonding, or other existing modes.

It should be noted that there are other implementations of the sealing structure 42, such as providing a plurality of magnets or adhesive plates attracting each other on the two walls of the through slot 41, or using a flexible connecting plate on one side of the through slot 41, and providing a magnet or adhesive plate on the outer wall of the sheath 4 on the other side of the through slot 41 to engage with the connecting plate.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
