Description

Breathing type anti-fog mask

technical field

The invention relates to a mask with anti-fog and haze functions, in particular to a breathing type anti-fog and haze mask.

Background technique

As a healthy daily necessities, a mask prevents harmful gases or dust in the air from entering the human body by filtering, and prevents the wind from directly hitting the face by blocking, especially during the epidemic of respiratory infectious diseases or in dust for a long time Wearing a mask is especially necessary when you are in a polluted environment.

For situations where it takes a long time to be in a polluted environment such as dust, the level of filtration of dust particles by the mask is mainly based on the filtration level of respirable dust with a particle size below 5 μm, because dust within this particle size range can It directly enters the alveoli and will have a great impact on human health after inhalation. This kind of dust will pass through the tiny pores of traditional masks and directly enter the respiratory system, causing harm to human health.

Compared with traditional gauze or medical masks, anti-smog masks use materials with a higher level of dust resistance or add a layer to block smog on the basis of traditional masks to ensure its filtering level of smog. However, the current anti-smog masks are often not tightly fitted to the face and are prone to air leakage; the extrusion force on the nose is large, the breathing space is small, the breathing is not smooth, and the comfort is poor; the filtering area is small and cannot meet the actual filtering needs; Barriers to glasses wearer's use still exist.

Contents of the invention

In view of this, the present invention provides a breathing anti-smog mask, which aims to ensure smooth breathing of the wearer under the premise of effectively blocking the smog.

In the above-mentioned breathing anti-fog mask, the breathing part includes an air-promoting unit and an exhaust-promoting unit, and the air-promoting unit is used to make the outside air flow through the mask body and blow into the cavity formed by the mask body and the wearer's face. body space, the exhaust-promoting unit is used to exhaust the gas exhaled by the wearer.

In the above-mentioned breathing anti-fog mask, the gas-promoting unit is a fan, and the fan is provided with a power source.

In the above-mentioned breathing anti-fog mask, the exhaust-promoting unit is a breathing valve.

In the above-mentioned breathing anti-fog mask, a cushion layer is also included, and the cushion layer is arranged inside the mask body or has an integrated structure with the mask body.

In the above-mentioned breathing anti-fog mask, it also includes a first cushion body, and the first cushion body is arranged at the contact place between the inner side of the mask body and the bridge of the nose.

In the above-mentioned breathing anti-fog mask, the first pad body is made of a material with variable shape.

In the above-mentioned breathing anti-fog mask, the first pad is also provided with a second pad, and the material of the second pad is softer than that of the first pad.

In the above-mentioned breathing anti-smog mask, the inside of the mask body is provided with a filter layer, and the promoting air unit makes the external air flow flow through the mask body and the filter layer and then blow into the mask body and wear. The outwardly protruding cavity space formed by the patient's face.

The beneficial effects produced by the present invention are:

The breathing anti-fog mask of the present invention has changed the structure of the traditional mask. By adding a small fan and a breathing valve to the mask body, a good air flow has been created inside the mask, and the mouth and nose tip are not in contact with the mask. Protruding to the outside, so that the mouth and nose have a larger breathing space, so that the wearer feels comfortable;

The cushion in the mask body enables the mask to fit well with the face. The shape-changing first cushion is set at the joint between the mask and the nose, and a second cushion is added inside the first cushion. Cushioning, which enhances the contact comfort of the nose and the first cushioning.

Detailed ways

The technical solutions of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

A kind of breathing type anti-fog mask as shown in Figure 1, comprises mouth mask body 1 and buckle ear strap 2, and the both sides of mouth mask body 1 is connected with buckle ear strap 2 respectively; Also comprises breathing portion, and breathing portion is located at mouth mask body 1.

The breathing part includes an air-promoting unit and an exhaust-promoting unit. The air-promoting unit is used to make the outside air flow through the mask body 1 and blow into the cavity space formed by the mask body 1 and the face of the wearer. The exhaust-promoting unit is used to make the wearer The exhaled gas is discharged.

It also includes a cushion layer, which is arranged inside the mask body 1 or has an integrated structure with the mask body 1.

It also includes a first pad, which is located at the contact between the inside of the mask body 1 and the bridge of the nose; the first pad is also provided with a second pad, wherein: the first pad is a material whose shape can be changed, and the second pad is made of a material that can be changed in shape. The material of the second cushion body is selected as softer material than the first cushion body.

The inboard of mouth mask body 1 is provided with filter layer 5, and as a kind of preferably, the material of filter layer 5 is PM2. Enter the cavity space formed by the mask body 1 and the wearer's face.

As a kind of embodiment, as shown in Figure 1, be a small fan 4 (a kind of preferred embodiment of promoting air unit) on the first side (the right side in the figure) of mouth mask body 1, the power source of fan 4 For the small lithium battery, the effect of the fan 4 is to provide the power of the air flow, and the outside air is blown into the inside of the mouth mask body 1 after passing through the filter layer 5, so as to enhance the flow smoothness of the air; on the second side of the mouth mask body 1 (Fig. The left side in the figure) is a breathing valve 3 (a preferred embodiment of the exhaust-promoting unit), through which the exhaled gas can be discharged.

By arranging the fan 4 and the breathing valve 3, a good air flow is created in the small space in the mouth mask body, which is convenient for the inhalation of clean air and the discharge of the exhaled gas, so that the human body feels smooth breathing. There will be fogging of the lens caused by the exhaled air not being discharged in time, which will affect the vision.

The inside of the mask body 1 is made of cotton material to make a soft cushion, which can fit well with the face. A plastic pad (i.e. a preferred embodiment of the first pad body) that can change the shape is provided at the position where the mask body 1 fits the bridge of the nose, and a sponge strip (i.e. the material is softer) is arranged on the inside of the plastic pad. A preferred embodiment of the second pad body) to enhance the contact comfort of the nose and the plastic strip. In addition, the mask body 1 protrudes outwards, so that the mouth and the tip of the nose are not in contact with the mask body 1, leaving a larger breathing space for the mouth and nose.

As mentioned above, the embodiments of the present invention have been described in detail. Obviously, as long as they do not substantially deviate from the inventive points and effects of the present invention and are obvious to those skilled in the art, they are also included in the protection of the present invention. within range.
