Description

a kind of mask

Technical field

The utility model belongs to the field of medical supplies, and in particular relates to a mask.

Background technique

There are many types of existing masks. The most common ones are disposable masks, dust masks and virus protection masks. However, professional masks are not widely used, and ordinary masks cannot be used in special occasions. For patients, using a large number of professional masks will cause a serious waste of resources. If masks with filtering effect are not used, there is no way to protect against infectious diseases. When an epidemic occurs, doctors will not have enough professional masks. can be used, medical resources are seriously insufficient.

Ordinary protective masks cannot be used against infectious diseases and cannot completely avoid the risk of infection. Therefore, in emergencies, a mask that can easily change the use environment is needed, and in order to prevent the waste of medical resources, it is necessary to prevent frequent replacement of masks. In this case, masks that can be reused are also needed.

Utility model content

The purpose of this utility model is to provide a resource-saving and reusable mask, which is especially suitable for people with dual needs for life and epidemic prevention.

The technical solution of the present invention is: a mask, including a dustproof cloth, an ear-hanging rope, a shield cover and a filter element. The dustproof cloth is a rectangular cloth, and the two ends of the two short sides of the dustproof cloth are seamed. At both ends of the ear-hanging rope, a rope buckle is provided in the middle of the ear-hanging rope. The rope buckle is a hollow cylinder. The middle part of the ear-hanging rope passes through the through hole in the center of the rope buckle. A knot is tied at the position. The knot in the middle of the ear-hanging rope is located at the end of the rope buckle away from the dust-proof cloth. The middle position of the dust-proof cloth protrudes to one side. The inner concave surface of the dust-proof cloth is provided with shielding sleeves close to the short sides. The shielding sleeve is close to the short side and the two long sides of the dustproof cloth and is seamed with the dustproof cloth. The two shielding sleeves are provided with openings on opposite sides. A filter element is arranged on the concave side of the dustproof cloth. The filter element is rectangular. The filter element The two short sides are respectively inserted into the openings of the two shielding sleeves.

Further, an interlayer is provided at the center of the inner recess where the dustproof cloth is located, and multiple layers of dustproof cloth are provided inside the interlayer.

Further, stainless steel wire is sewn inside one long side of the dustproof cloth.

Further, the ear-hanging rope adopts a rectangular rope.

Furthermore, the filter element adopts an anti-virus filter element.

The advantages and positive effects of this utility model are:

1. Due to the use of ear-hanging ropes and rope buckles, it can prevent traditional masks from constantly compressing the ears through tightness, and it can also prevent ordinary masks from being unable to adapt to all face shapes, causing the mask to strangle the user's ears. The pressure on the face makes the user very uncomfortable. The rope buckle and the knot of the ear-hanging rope can effectively avoid the pressure caused by the elastic band. By manually adjusting the position of the knot, you can find the most comfortable length of the ear-hanging rope. Effectively improves user comfort and can adapt to more people.

2. Due to the use of raised dust-proof cloth, it avoids the pressure of traditional masks on the face and improves the user's comfort level.

3. Since the inner concave surface of the dust-proof cloth is provided with an interlayer, multiple layers of dust-proof cloth can be installed to improve the filtration effect of dust and dust, and increase the air filtration effect of the mask.

4. Due to the use of a shielding sleeve to plug into the filter element, the virus filtering device and the mask itself are separated, and can be used on different occasions. The filter element can be discarded and replaced with a new one after use, and the mask itself can be cleaned and disinfected. Replacement of the filter element can effectively save masks and prevent the waste of masks. It only needs to replace the filter element, saving resources, and the structure of the shielding sleeve can facilitate the replacement and use of the filter element.

Detailed ways

The utility model will be described in detail below in conjunction with the accompanying drawings.

As shown in Figure 1-3:

A mask, including a dustproof cloth 1, an ear-hanging rope 2, a shield cover 4 and a filter element 5. The dust-proof cloth 1 is a rectangular cloth, and the two short sides of the dust-proof cloth 1 are sewn with hanging ears at both ends. At both ends of the rope 2, a rope buckle 3 is provided in the middle of the ear-hanging rope 2. The rope buckle 3 is a hollow cylinder. The middle part of the ear-hanging rope 2 passes through the through hole in the center of the rope buckle 3. A knot is tied in the middle of the ear-hanging rope 2. The knot in the middle of the ear-hanging rope 2 is located at the end of the rope buckle 3 away from the dust-proof cloth 1. The middle position of the dust-proof cloth 1 protrudes to one side, and the inner concave surface of the dust-proof cloth 1 is close to The short sides of the shielding sleeves 4 are respectively provided with shielding sleeves 4. The shielding sleeves 4 are close to the short side and the two long sides of the dustproof cloth 1 and are seamed with the dustproof cloth 1. The two shielding sleeves 4 are provided with openings on opposite sides. A filter element 5 is arranged on the concave surface of the dust cloth 1. The filter element 5 is rectangular, and the two short sides of the filter element 5 are respectively inserted into the openings of the two shielding sleeves 4.

The dust-proof cloth 1 is located in the center of the inner recess and is provided with an interlayer 6, and multiple layers of dust-proof cloth 1 are provided inside the interlayer 6.

A stainless steel wire is sewn inside one long side of the dustproof cloth 1 .

The ear-hanging rope 2 adopts a rectangular rope.

The filter element 5 adopts an anti-virus filter element.

The working process of this example:

During use, first decide whether to add filter element 5 according to the use situation. When there is no need to add filter element 5, you only need to place the mask on the face, find the most comfortable situation by adjusting the length of the ear-hanging rope 2, and then hang it Tie a knot in the middle of the ear rope 2 away from the dustproof cloth 1. Fix the length of the ear rope 2 through the rope buckle. Finally, press the stainless steel wire of the dustproof cloth 1 to fit the face. Disinfect and clean the mask after use. It can be used twice.

If you need to use the filter element 5, first plug the two short sides of the filter element 5 into the opening of the shielding sleeve 4, press the filter element 5 to fit the concave side of the dust-proof cloth 1, and adjust the length of the ear-hanging rope 2 to find it. For the most comfortable situation, then tie the middle position of the ear-hanging rope 2 away from the dust-proof cloth 1, fix the length of the ear-hanging rope 2 through the rope buckle, and finally press the stainless steel wire of the dust-proof cloth 1 to fit the face. If the filter element 5 needs to be replaced after use, you only need to take out the filter element 5 and throw it away, and disinfect and clean the mask.
