Description

Mask

Technical Field

The utility model relates to a mask, and belongs to the technical field of medical masks.

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 mask may be classified into an air filtering type mask and an air supplying type mask.

Degree of adhesion. The mask side leakage prevention design is a technical requirement for preventing air from being inhaled into human body through gaps between the mask and the face of the human body without filtering. Where the air flows first, as does the water flow, the air flows first with little resistance. When the shape of the mask is not closed to the human face, dangerous objects in the air can leak into the mask from the non-closed position and enter the respiratory tract of a human body. Then, even if you choose a mask with a better filter material. And can not guarantee your health. Many foreign regulatory standards dictate that workers should periodically perform mask fit tests. The purpose is to ensure that a worker selects a mask with a proper size and wears the mask according to the correct steps.

The wearing is comfortable, so that workers can enjoy wearing the clothes constantly in a workplace and improve the working efficiency of the workers. The existing maintenance-free mask is not required to be cleaned or replaced, and is discarded after dust blocking saturation or mask damage, so that the sanitation of the mask is guaranteed, and the time and the energy for maintaining the mask by workers are saved. Moreover, many masks are in an arched shape, which can ensure good fit with the face and keep a certain space at the mouth and nose, and is comfortable to wear.

SUMMERY OF THE UTILITY MODEL

In view of this, the utility model provides a mask, which has better sealing performance, is more comfortable to wear, is more convenient to replace mask cloth, and can easily realize switching of masks with different layers.

The utility model solves the technical problems by the following technical means: the utility model provides a mask, comprises gauze mask frame and gauze mask, gauze mask frame is including setting up at silica gel circle all around, and the middle part of silica gel circle is hollow structure, the silica gel circle is connected with the cavity square frame that the middle part of gauze mask frame set up, and cavity square frame top is provided with the arc recess all around, and the cavity square frame is embedded to have gauze mask cloth, and gauze mask cloth's periphery sets up in the arc recess, has the chucking square frame in the arc recess, gauze mask frame both sides limit is provided with hangs the rope, and gauze mask frame upper portion is provided with nose shape silica gel shell.

The thickness of the silica gel ring is 1-2.5cm, the edges of the peripheral bottom of the silica gel ring are all arc-shaped, and the edges with the width of 0.5-1cm and the thickness of 0.1-0.3mm are arranged at the lower part of the arc shape.

The height of the hollow square frame is 3-5 cm.

The hanging rope is an elastic rope.

The hollow structure in the nose-shaped silica gel shell.

This patent adopts the gauze mask frame to detain on people's face, and the middle part of silica gel circle is hollow structure simultaneously, the silica gel circle is connected with the cavity square frame that the middle part of gauze mask frame set up, because the flexibility of silica gel, the bottom border all around of silica gel circle is arc, and arc lower part is provided with the width and is 0.5-1cm, the thickness is 0.1-0.3 mm's border, and the border is very thin silica gel, when wearing, can have certain elasticity to satisfy the people of different face types, make relatively sealed all around.

Meanwhile, the nose-shaped silica gel shell is arranged on the upper portion of the mask frame, and a hollow structure inside the nose-shaped silica gel shell can be buckled on the bridge of the nose of a person to guarantee sealing.

Simultaneously, cavity square frame top is provided with the arc recess all around, and the cavity square frame is embedded to have mouthful cover cloth, and the periphery of mouth cover cloth sets up in the arc recess, has the chucking square frame in the arc recess, can with gauze mask card on the cavity square frame, adopts the chucking square frame to block the border all around of mouthful cover cloth in the arc recess simultaneously, realizes mouthful sealed all around of cover cloth, if mouthful cover cloth has used the back, can be quick take out the chucking square frame to quick change mouthful cover cloth. Meanwhile, the structure of the utility model can fold a plurality of layers of mask cloth together, thereby clamping the mask cloth in the arc-shaped groove, and flexibly adopting one or more layers of mask cloth to adjust the filtering precision. Meanwhile, the replacement speed is high.

The utility model has the beneficial effects that: the leakproofness is better, and wears more comfortablely, and it is also more convenient to change gauze mask, and the switching of the different number of piles gauze mask of realization that can relax.
