Description
Technical Field
The invention relates to the field of medical protection, in particular to a nanoscale melt-blown fabric environment-friendly mask with low air resistance.
Background
The mask is a sanitary article, generally refers to a device which is worn at the mouth and nose part and used for filtering air entering the mouth and nose so as to prevent harmful gas, smell and spray from entering and exiting the mouth and nose of a wearer, and is made of gauze or paper and the like. The mask has a certain filtering function on air entering the lung, and has a very good effect when being worn in respiratory infectious diseases and working in environments polluted by dust and the like.
The body of the medical mask used at present adopts multilayer melt-blown cloth to stack, and particles, viruses and droplets in the air are blocked by the melt-blown cloth, so that the effect of preventing infectious diseases is achieved. The mask in the prior art has the following defects: (1) the mask is attached to the face, so that a good germ separation effect can be achieved, and meanwhile, due to the fact that the melt-blown cloth is good in air tightness, particularly when the mask exhales, the air resistance of the mouth and the nose of a person is high when the mask breathes, and the mask is not smooth in breathing. When the check valve is attached to the mask, the air resistance is low, but the cost is high, which is not favorable for widespread use. (2) When infectious diseases (particularly respiratory infectious diseases) are prevalent, masks are not in demand in the market and are in shortage as a means for effective protection. Under the condition of the mask lacking rapidly, people need to keep the mask taken off properly when having meals, cleaning faces and having a short rest so as to be reused later, but due to the particularity of the mask, the inner side of the mask is in contact with the mouth and the nose and cannot be placed at will, if bacteria are adhered, the health of a human body is directly harmed, and therefore the mask which is rapid and convenient to store needs to be developed.
Disclosure of Invention
In order to solve the existing problems, the invention discloses a nanoscale melt-blown fabric environment-friendly mask with low air resistance, which has the following specific technical scheme:
a nanoscale melt-blown fabric environment-friendly mask with low air resistance comprises a square mask body formed by stacking and pressing multiple layers of melt-blown fabrics and hangers arranged on two sides of the mask body, wherein bent strips are arranged on the inner side of the top of the mask body; the mask is characterized in that a plurality of ventilation strips are arranged inside the mask body at the positions where the two ends of the mask body are stacked and pressed by melt-blown cloth, the ventilation strips are hollow thin tubes, one side of each ventilation strip is connected with the inner side of the mask body, and the other side of each ventilation strip penetrates through the side edge of the mask body and is communicated with the outside of the mask body;
when the mask is used, when a human body inhales, external air flow is filtered by the mask body to breathe, and at the moment, the blocking piece blocks the inside of the ventilation strip in an inclined manner, so that the ventilation strip is not exchanged with the external air flow; when the human body exhales the airflow, the exhaled airflow drives the separation blade to deform, one end of the separation blade leaves the inner side of the breathable strip, and therefore the airflow smoothly leaves the mask body through the breathable strip.
Furthermore, a brace placing cavity formed by sewing melt-blown cloth is arranged on the inner side of the stacking and pressing part of the melt-blown cloth at the two ends of the mask body, the brace placing cavity is in a long strip shape and is of a hollow structure with an opening at one side and a sewing at one side, and the brace placing cavity is vertically arranged outside the two sides of the mask body; a brace is arranged in the brace placing cavity, one side of the brace is fixedly connected with the sewing side of the inner side of the brace placing cavity, and the other side of the brace slightly extends out of the brace placing cavity; when in use, the two braces at the two sides of the mask body are tightened, and the two ends of the mask body are condensed into a bundle; and then the two braces are tightened respectively, and at the moment, the inner side of the mask body is condensed to realize storage.
Further, gauze mask body bottom is provided with the lower jaw laminating portion that forms by the melt-blown cloth multilayer piles up, laminating lower jaw is narrow structure under the width, through sewing up fixed connection in gauze mask body below position, during the use, laminating lower jaw cladding live people's face lower jaw part.
Furthermore, at least one bending piece with deformation performance is fixedly arranged at the joint of the lower attaching jaw part and the mask body, the bending piece is of an integrated structure and is of a structure with two narrow ends and a middle narrow structure, and two ends of the bending piece are respectively arranged in the lower attaching jaw part and the mask body; when in use, the bending piece is attached to the lower jaw to be bent, so that the attached lower jaw part is attached to the lower jaw of a human body.
Furthermore, the bending piece is arranged inside the joint lower jaw part and inside the mask body in a sewing mode.
The invention has the beneficial effects that:
(1) the ventilation strip is adopted, and the exhaled gas can be smoothly discharged from the ventilation strip through the inclined blocking piece of the ventilation strip, so that the gas resistance is low; the air can be prevented from entering the mouth and the nose from the air permeable strip during air suction while breathing is smooth, and the barrier property is guaranteed; compared with a one-way valve, the air permeable strip has a simpler structure and low cost.
(2) The brace design has been adopted to gauze mask body both sides, can be taut with the gauze mask through the brace, can be fast, convenient storage, through hanging the ear to on the couple afterwards, the inboard mutual condensation of gauze mask avoids with air direct contact, is favorable to gauze mask increase of service time.
(3) Through setting up laminating jaw portion structure, can be to the shape of human face and jaw, buckle in jaw department through buckling the piece, be favorable to gauze mask and the better laminating of human body, protect more comprehensively, convenient to use.
