Abstract

The utility model discloses a color-changeable warning mask, which is characterized in that: the mask comprises a mask body and ear belts arranged on two sides of the mask body, wherein the mask body comprises an outer protective layer, a humidity sensing color changing layer, a moisture absorption layer, a filter layer and a water repellent layer from outside to inside. Whether the interior of the mask is wetted or not can be clearly observed through the humidity-sensitive color-changing layer, so that the adsorption quantity of pollutants on the mask can be known, and the mask can be conveniently replaced at any time; whether the body temperature of the wearer is normal can be monitored in real time through the temperature sensing color-changing belt.

Description

Color-changeable warning mask

Technical Field

The utility model relates to the technical field of protective articles, in particular to a color-changeable warning mask.

Background

The mask is a sanitary article, is generally worn on the mouth and nose for filtering air entering the mouth and nose so as to achieve the effect of blocking harmful gas, smell, spray, virus and other substances, and is made of gauze or paper and the like. The mask has a certain filtering effect on air entering the lung, and is essential for making individual respiratory health protection when respiratory infectious diseases are popular, working in dust and other polluted environments, or places with frequent air pollution and haze, so that the mask has a very good protection effect when worn.

Among the prior art, general gauze mask adopts the non-woven fabrics of one deck or multilayer to make mostly, but protective mask wears a period of time after, and inside can become moist, and the surface will adsorb a lot of harmful particulate matter, and then arouses the inefficacy of gauze mask, continues to wear this gauze mask and probably causes harm to the human body. Therefore, there is a need for a mask that can clearly observe whether the inside of the mask is affected with moisture, so as to know the adsorption amount of the pollutants on the mask, and facilitate replacement at any time.

SUMMERY OF THE UTILITY MODEL

The present invention aims to provide a color-changeable warning mask which solves one or more of the above-mentioned problems of the prior art.

According to one aspect of the utility model, the color-changeable warning mask comprises a mask body and ear bands arranged on two sides of the mask body, wherein the mask body comprises an outer protective layer, a humidity-sensing color-changing layer, a moisture absorption layer, a filter layer and a water-repellent layer from outside to inside.

In some embodiments: the temperature sensing color changing belt is arranged on the surface of the outer protective layer, mainly adopts a reversible temperature sensing color changing material, and can change color when the temperature reaches above 38 ℃. Therefore, whether the body temperature of the mask wearer is normal or not can be detected and found in real time through the temperature sensing color changing strip.

In some embodiments: the humidity-sensitive discoloring layer is mainly a silica gel layer containing cobalt chloride. Therefore, the cobalt chloride becomes a hydration state and turns red after absorbing water, so that whether the mask is failed or not can be judged.

In some embodiments: the moisture absorption layer is made of moisture absorption cloth made of pure cotton fiber cloth or hydrophilic spun-bonded non-woven fabric. Therefore, the water absorption performance of the mask can be improved, and the service life of the mask can be prolonged.

In some embodiments: the filter layer mainly adopts activated carbon non-woven fabrics. Thus, a large amount of harmful substances in the air can be adsorbed by the activated carbon with good adsorptivity.

In some embodiments: the water-repellent layer mainly adopts water-repellent spun-bonded non-woven fabric. Therefore, moisture can be isolated, and harmful particles are prevented from being absorbed into human bodies through moisture to cause harm to human bodies after the moisture absorbed by the moisture absorption layer is excessive.

Has the advantages that:

according to the color-changeable warning mask, whether the interior of the mask is wetted or not can be clearly observed through the humidity-sensing color-changing layer, so that the adsorption quantity of pollutants on the mask can be known, and when the color changes, warning replacement is carried out; whether the body temperature of the wearer is normal can be monitored in real time through the temperature sensing color-changing belt.

Detailed Description

In order to make the technical solutions better understood by those skilled in the art, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only partial embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The present invention will be described in further detail with reference to the accompanying drawings.

As shown in fig. 1, the color-changing warning mask comprises a mask body 1 and ear bands 2 fixedly connected to two sides of the mask body 1, wherein an outer protective layer 11 is arranged on the outermost side of the mask body 1.

As shown in fig. 2, a structure of the outer protective layer 11 is provided, a temperature-sensitive color-changing strip 111 is provided on the surface of the outer protective layer 11, the temperature-sensitive color-changing strip 111 mainly adopts a reversible temperature-sensitive color-changing material, and changes color when the temperature reaches above 38 ℃, so that whether the body temperature of the mask wearer is normal can be detected and found in real time through the temperature-sensitive color-changing strip.

As shown in fig. 3, the mask body 1 is provided with an outer protective layer 11, a moisture-sensitive discoloration layer 12, a moisture absorption layer 13, a filter layer 14 and a water-repellent layer 15 from the outside to the inside.

In some embodiments, the humidity-sensitive color-changing layer 12 is mainly a silica gel layer containing cobalt chloride, the cobalt chloride becomes a red cobalt chloride solution after absorbing water and becomes a hydrated state, and whether the mask absorbs too much water and fails can be judged by the humidity-sensitive color-changing layer 12 becoming red.

In some embodiments, the moisture absorption layer 13 is a moisture absorption cloth made of pure cotton fiber cloth or hydrophilic spun-bonded non-woven fabric, so that the moisture absorption performance of the mask can be improved and the service life of the mask can be prolonged.

In some embodiments, the filter layer 14 is mainly made of activated carbon nonwoven fabric, and thus absorbs a large amount of harmful substances in the air with good adsorptivity of activated carbon.

In some embodiments, the water-repellent layer 15 is mainly made of water-repellent spun-bonded nonwoven fabric, so as to isolate water and prevent harmful particles from being absorbed into human body through water after the water absorbed by the moisture absorption layer is too much, thereby causing harm to human body.

When the mask moisture absorption layer 13 is full due to excessive moisture absorption in the using process of the color-changeable warning mask, the moisture-sensitive color-changing layer 12 can be changed into red to give a warning to replace the mask, so that the mask is prevented from being used excessively and being replaced in time to prevent harmful particles in the absorbed air.

The foregoing is only a preferred form of the utility model and it should be noted that similar variations and modifications could be made by those skilled in the art without departing from the inventive concept herein, which is also considered to be within the scope of the utility model.
