Description

Functional mask

The present invention relates to a functional mask, and more particularly, a fan is mounted on the mask to smoothly discharge and remove moisture and carbon dioxide therein, and is convenient to use by installing a control board and a battery for the blower. The present invention relates to a functional mask having excellent filtration performance against external contaminants.

In general, the mask is a device for protecting the human respiratory system from contaminated air or cold air. Typically, a mask for protection of the respiratory organ from cold air, a dust mask for protecting the respiratory organ from dust, etc., and foreign substances from the outside Or it is classified as a medical mask that prevents the penetration of bacteria and at the same time blocking the discharge or discharge of bacteria from the user to the outside.

In recent years, environmental pollution has become a serious problem, and the environment atmosphere where ordinary people live includes a large number of foreign substances such as fine dust, and such fine dust and yellow dust flow into the human respiratory tract, causing various diseases. It is fatal to you.

Here, the fine dust is small and small dust particles that are invisible to our eyes, and contains a lot of air pollutants, such as sulfur dioxide, nitrogen oxides, lead, ozone, carbon monoxide, etc., the source of these emissions is caused by artificial It is divided into natural occurrence such as yellow dust, sand dust of dust, volcanic ash, and fire caused by forest fire. When a person inhales the fine dust, it penetrates deep into the alveoli and prevents various respiratory diseases such as asthma, headache and atopy. If the elderly are persistently inhaled, there is a serious problem leading to death of lung disease by reducing immune function.

In addition, in general, a lot of dust is generated in the working environment, such as paper mills, textile mills, quarries, etc. In addition, a large amount of toxic gas is generated in the working environment of various chemical plants and metal processing plants such as welding, smelting, plating.

Inhalation of dust, yellow dust, or harmful dust can cause fatal diseases such as lungs, as well as cause asthma, and prevents dust and harmful substances from entering the respiratory system. Wear a dust mask to protect your health.

In addition, hemispherical dust masks are often used by filter papers that are simple, light, and relatively inexpensive, and can be used once or several times depending on the degree of contamination of the workers. .

However, the conventional dust mask as described above simply forms a mask body made of woven paper, and thus has a problem that the dust-proofing effect is lowered due to a decrease in durability of the mask body, and in particular, the mask life is significantly shortened.

In addition, when wearing a mask, the adhesion to the face is lowered, the dust-proof effect is lowered, and the structure is simply worn on the ear, there is also a wear problem, such as a decrease in adhesion to the face and pain in the ear when worn for a long time. In addition, inhalation and exhalation in the same direction, the main body is wet when used for a long time, if bad, bad smell occurs, such as long-term wearing of the mask is not very good clean.

Moreover, it is urgent to develop masks that are safer and have more excellent function in keeping with the phenomenon that bacterial resistance becomes stronger and mutations occur and new infectious diseases emerge.

outlets

125, 127 for discharging the air discharged from the mouth. It accommodates the filter 160 installed in the 112, 113, 121, 122, 123 and at the same time the outside through the upper portion 119, the lower portion 117 and the

side surfaces

118a, 118b of the skeletal portion (110, 120) Cover portion 130 and the skeleton portion 110 coupled to the front surface at regular intervals with the

skeleton portion

110, 120 so that air can be introduced into the inlet (111, 112, 113, 121, 122, 123) Is coupled to the back of the 120, the face portion surrounding the mouth of the human body and the skeletal portion (110, 120) includes a surface portion 140 to be in close contact It consists in the.

That is, the functional mask 100 according to the present invention has a discharge port (125, 127) for discharging exhaled air is formed in the lower portion of the skeletal portion (110, 120) formed in a convex shape to surround the face portion around the mouth of the human body Exhaling air with a large proportion of heavy gases such as carbon dioxide can be more effectively discharged to the outside. In addition,

external air inlets

111, 112, 113, 121, 122, and 123 are formed at upper portions of the

skeletal parts

110 and 120, and are disposed on a front surface of the

skeletal parts

110 and 120, and the intake ports ( A cover 130 for accommodating the filter 160 installed in the 111, 112, 113, 121, 122, and 123 includes the upper portion 119, the lower portion 117, and the side surface 118a of the

skeleton portions

110 and 120. , 118b is formed so that the outside air is coupled to the front surface at regular intervals with the skeletal portion (110, 120) to be introduced into the inlet (111, 112, 113, 121, 122, 123), By lowering the pressure of the air flowing into the mask from the outside to pass through the filter 160 slowly and to allow air to circulate inside the mask, it is possible to maximize the filtration performance for the external contaminants.

In addition, it is coupled to the back of the

skeleton portion

110, 120 and the face portion around the mouth of the human body and the respirator such as the mouth and nose through the face portion 140 to tightly adhere to the skeleton portion (110, 120) By ensuring the adhesion of the skeleton portion, the filtration performance of the functional mask 100 can be further improved.

Coupling structure of the skeletal portion (110, 120) and the cover 130 is the outside air through the upper portion 119, the lower portion 117 and the side (118a, 118b) of the skeletal portion (110, 120) Cover portion 130 is coupled to the front surface of the skeletal portion (110, 120) at regular intervals so as to flow into the (111, 112, 113, 121, 122, 123) If the structure is not particularly limited, for example, the

skeleton portion

110, 120 and the cover 130 may be formed to be coupled to each other by a magnetic coupling method using a magnet and iron pieces (171, 172). Such a magnetic coupling method has an advantage of providing a stable coupling force between the

skeletal parts

110 and 120 and the cover part 130, and at the same time facilitate assembly and disassembly. To this end, fixing

grooves

116a and 116b of magnets or pieces of

iron

171 and 172 may be formed on the front surface of the skeleton portion 110.

Here, the filter 160 disposed between the

skeletal parts

110 and 120 and the cover part 130 is excessively in close contact with only the

inlet

112 and 122 at the center thereof, and thus the

inlet ports

111, 121, 113, and 123 of both sides. In order to prevent the phenomenon of disturbing the air flow during the intake of the outside air, the inlet separation rib 112a may be formed around the

inlets

112 and 122 of the center of the front frame 110.

The structure of the

skeletal parts

110 and 120 is not particularly limited, and for example, the front frame 110 having at least two

front suction ports

111, 112 and 113 formed thereon and the

front suction ports

111 and 112 formed thereon. The first inlet 125 and the first outlet 125 having a structure in communication with the corresponding one of the first and

second inlets

121, 122, and 123 and receiving the exhaled air discharged from the mouth at a lower portion thereof and redirecting the lower direction. The back frame 120 having the second outlet 127 for discharging air received from the outlet 125 in a downward direction may be formed as a skeleton portion having a structure coupled thereto. At this time, the coupling structure of the front frame 110 and the rear frame 120 is not particularly limited, for example, it can be achieved by the bolt nut coupling structure 190.

As such, the

skeleton parts

110 and 120 formed of the front skeleton 110 and the rear skeleton 120 can be easily assembled and disassembled, and can effectively suck air from the outside, and are discharged from the user's mouth. There is an advantage that can exhale exhaled air to outside smoothly.

Here, by forming the exhalation discharge film 126 made of a flexible silicone material in the first outlet 125, the exhalation air discharged from the user's mouth is obtained to smoothly change the direction downward and at the same time with the exhalation air The first outlet 125 may be configured such that the outside air filtered through the filter 160 is not mixed.

That is, the exhalation discharge membrane 126 is firmly coupled to the upper and both side portions of the first outlet 125 by a method such as adhesion, and the lower portion of the first outlet 125 is the exhalation exhaust membrane 126. ) So that the first outlet 125 is entirely sealed when the mask user inhales and inflows of external air, thereby opening the

suction ports

111, 112, 113, 121, 122, and 123. In order to stably introduce external air, and when the mask user exhales and exhales, the exhalation membrane 126 is not coupled with the first outlet 125. Through the lower portion of the exhaled air can be smoothly discharged to the outside.

In addition, the functional mask 110 allows the blower fan seating part 114 to be formed at one of the

front suction ports

111, 112, and 113 of the front frame 110, and the blower fan seating part 114 is provided. The blowing fan 150 for sucking outside air is formed in the rear suction port 122 of the rear frame 120 corresponding to the formed front suction port 112. And it may be configured to be provided between the fixing portion 124. That is, a blower fan for sucking external air by forming a seating portion 114 and a fixing portion 124 in the front suction port 112 of the front frame 110 and the rear suction port 122 of the rear frame 120, respectively. By installing the 150, the filtered outside air can be effectively supplied into the mask 100 so that the user can breathe more comfortably.

In this case, empty spaces are formed on both sides of the front frame 110 and the rear frame 120 by the combination of the front frame 110 and the rear frame 120, respectively. A PCB 152 for controlling the driving of the blower fan 150 is mounted in the 128b, and a battery for driving the blower fan 150 in an empty space on the other side of the empty spaces (not shown). 151 is configured to be mounted, while having a compact structure and at the same time can ensure stable external air inflow performance by the blowing fan 150, a functional mask 100 that can conveniently control the blowing fan 150 ) Can be prepared.

Here, switches 182 and 183 for convenient driving of the blower fan 150 and a charging terminal unit 181 for charging the battery 151 may be formed on one side upper end and the lower end of the rear frame 120. .

In addition, the functional mask 100 is a personal fine dust notification air filtration fashion mask that is easy to breathe, for example, by applying a small blower, a dust mask that is much easier to breathe, interlocking with the fine dust information of the region, recommended to wear when needed It can be implemented in the form of a smart mask, and when connected to the dock, the dock can be designed to employ a notification function with the LED, the control by providing a respiratory healthcare App in conjunction with the smartphone It can be configured to.

In addition, the functional mask 100 may be implemented as a filter replacement economic mask without the burden of maintenance costs due to the high-performance mask having a sealing force of the gas mask level, fine dust generation concentration, frequency increase by applying medical liquid silicone.

On the other hand, the functional mask 100 may be applied to the internal structure to prevent direct sunlight + air circulation by the skeleton portion (110, 120). The internal structure of the mask prevents the air sucked by the blower fan 150 from directly contacting the face, and forms a structure inclined to circulate / exhaust the air in the mask, thereby preventing dust from entering the gap. Air can be pushed out of the mask to effectively block out crevices.

In addition, by applying the inlet separation structure design, it is possible to prevent the choking by separating the air intake by the blower fan 150 and the air intake by the user's breathing, the user stepped through (the function of the filter is lost) At this point, it is possible to form a structure in which a mask can be used even when the battery 151 is discharged.

In addition, the material of the functional mask is a flexible and lightweight plastic material for covering the face, for example, polycarbonate (PC + GF10) can be used, the power part for the complete separation, complete cleaning, waterproof packing, close to the face It can be prepared using a medical liquid silicone or the like.

On the other hand, the surface portion 140 may be made of a flexible material, the back surface of the skeleton portion 120 in a shape corresponding to the front shape of the surface portion 140 for the coupling with the surface portion 140 The fitting coupling portion 129 of the protruding form is formed, and the protruding coupling groove portion 146 coupled to the fitting coupling portion 129 is formed in the faceted portion 140 so that the fitting coupling portion ( 129 and the coupling groove 146 may be formed in a structure in which the skeletal portion 120 and the surface portion 140 are coupled to each other.

At this time, the fitting coupling portion 129 has a cross-sectional thickness (W1) in the direction of the skeletal portion 120 to form a structure 20 to 30% thicker than the cross-sectional thickness (W2) in the direction of the facet portion 140 In addition, while achieving a stable coupling of the skeletal portion 120 and the surface portion 140, it is possible to manufacture a functional mask that is easy to separate and bond the skeletal portion 120 and the surface portion 140.

That is, the faceted portion 140 is formed of a flexible silicone material as a whole, so that the upper rib 146a and the lower rib 146b of the coupling groove 146 of the protruding shape can be flexibly adjusted to each other. And the fitting coupling part 129 has a structure in which the cross-sectional thickness W1 in the direction of the skeletal portion 120 is 20 to 30% thicker than the cross-sectional thickness W2 in the direction of the faceted portion 140. When the skeleton portion 120 and the shell portion 140 are coupled, a stable mask and high sealing force are achieved, and at the same time, the separation and coupling of the skeleton portion 120 and the shell portion 140 is easy to manufacture a functional mask. can do.

On the other hand, the functional mask 100 except for the rear center of the rear frame 120, both

rear portions

120a and 120b from the rear center except for the front center of the front frame 110, the front It can be configured so that the thickness on the plane is formed thicker than the front sides (110a, 110b) from the central portion. The thickness ratio configuration of the front skeleton 110 and the rear skeleton 120 can provide stability and robustness to the functional mask 100 to prevent deformation or distortion that may occur due to various forces applied from the outside. have.

Specifically, when the functional mask 100 is applied to some dust, gas masks, etc., the thickness of the product should be thinner toward the side, if simply reducing the thickness of the injection molded body as the strength or hardness is weakened There is a risk of damage. That is, when manufactured by making the thickness of the front skeleton and the back skeleton injection molding similar to the conventional general design method, there is a risk of breakage, there is a fear of the distortion of the mask itself, resulting in air leakage. In addition, the functional mask 100 is coupled to a separate band or head strap to be worn on the user's face at both ends to support the weight and to receive a relatively large force, screws, etc. assembled for coupling between the skeleton parts Since the force from the coupling member of the, except for the rear center of the rear skeleton 120, both

rear portions

120a, 120b from the rear center except the front center of the front skeleton 110, the front By configuring the planar thickness to be formed thicker than the front side both sides (110a, 110b) from the central portion, it is possible to further improve the stability and robustness of the functional mask 100.

Herein, the coupling

member forming portions

110c and 120c such as a piece hole in which coupling members such as screws are formed in the front skeleton 110 and the rear skeleton 120 are respectively formed of the front skeleton 110 and the rear skeleton 120. For example, at a distance of 1 to 3 cm from both ends.

At least one type of information selected from the group consisting of a state of air sucked into the functional mask 100, a state of a filter, a state of a mask closed, and an oxygen concentration around the rear surface 120 may be displayed on one upper surface of the rear frame 120. Status indicator 120d may be formed.

In other words, in the case of the conventional dust and gas masks, in order to check the sealing force, the breakage condition (remaining life) of the filter, etc., use both hands to block the inlet of the product and experiment or remove the mask and remove the filter. Separate cumbersome measures were required. However, the functional mask 100 of the present invention is selected from the group consisting of, for example, the state of the air sucked into the functional mask 100 using the LED, the state of the filter, the closed state of the mask, and the surrounding oxygen concentration. By forming a status indicator (120d) that can display at least one kind of information, there is an advantage that the user can conveniently check a variety of information related to the use of the functional mask without using a hand.

When the user wears the functional mask 100 and performs daily activities or works, the angle of the status indicator 120d is appropriately adjusted so that the light of the status indicator 120d does not disturb the user's view. It can be adjusted to form. In addition, the formation angle and the structure of the status indicator 120d may be implemented at an appropriate angle so that the user can consciously lower the direction of the gaze when it is necessary to check the current state and various information of the functional mask 100. have.
