Description

{FUNCTIONAL MASK HAVING SEPERATED TYPE FILTER}

The present invention relates to a functional mask, and more particularly, to a functional mask having a body formed in a shape corresponding to a face portion so as to surround a face portion; A connection hose having a predetermined length and connected to the body and the one end so as to communicate with each other, Wherein the filter hose is connected to the other end of the connection hose so as to communicate with each other and is formed of a breathable material and has a hollow inside or a pouch type filter, The present invention relates to a functional mask having improved breathability and filtering efficiency through a detachable filter.

As is known, the mask is composed of a cloth-like body 1 cut in a substantially rectangular shape as shown in Fig. 1 and a wearable strap 3 connected in a ring shape on both sides of the body so as to hang on the wearer's ear. It should have a good respiration and at the same time have a filtering effect to prevent dust and bacteria from entering.

The mask has an air volume equal to the area of the body surrounding the face, and the intake and ventilation properties are varied depending on the degree of filtering of dust and bacteria. For example, the breathability and breathability of the disposable mask, It can be seen that the dust mask is more than the breathability and breathability of a filterable dust mask.

This is because a filter layer having a nonwoven fabric-like filter form is laminated in 3 to 6 layers in order to maximize the filtering effect of dust and germs.

That is, the conventional mask has a paradoxical effect that the breathing is difficult due to the inhaling property and the breathability being lowered as the filtering effect is higher, and the problem of wetting the face during respiration in a low temperature environment such as in the winter season, There was a problem.

Hereinafter, a functional mask having improved breathability and filtering effects through a removable filter will be described in more detail with reference to the accompanying drawings.

The present invention includes a body 100, a connection hose 200, and a filter so that the air filtered through the filter is supplied to the body through the connection hose so that a sufficient amount of comfortable air can be sucked.

Referring to FIGS. 2 to 4, the body 100 is formed to have an area enough to cover the nose, mouth, and the like of a user. The body 100 has a strap- A band (not shown) is provided.

The body 100 may be formed of a material that has excellent adhesion and does not cause irritation or discomfort to the skin when worn, for example, a latex material.

Conventional masks, for example, disposable masks made of pure cotton yarn are worn by the edges of the body (especially the left and right sides among the four corners) depending on the face shape when worn, and foreign substances or fine dust in the air are introduced into the gaps There is a problem that the efficiency of the mask is lowered, and the facial line becomes unclear, thereby deteriorating the esthetics.

The present invention can prevent the entry of foreign substances or fine dust in the air when worn by forming the body 100 from a material having a high adhesion force, and it is possible to expect an effect of saving the face line as it is and an effect of improving aesthetics .

In addition, the body 100 includes a first valve 110 for allowing air to flow while being opened during inhalation, and a second valve 120 for discharging air while being expelled.

The first valve 110 is connected to one end of the connection hose 200 connected to communicate with the filter, and is configured to be able to open the interior of the connection hose 200 when it is inhaled to suck the filtered air.

FIG. 5 is a view illustrating a first valve 110 according to an embodiment of the present invention.

The first valve 110 includes a first housing 111 protruding outward from the lower portion of the body.

The first housing 111 is formed in a cylindrical shape having a predetermined length so as to smoothly enter the first housing 111 without being scattered when moving along the inside of the first housing by imparting straightness to the air introduced at the time of inhalation.

The first housing 111 is detachably coupled to the connection hose 200 so as to communicate with the connection hose 200. A method of detachably coupling the first housing 111 and the connecting hose 200 may be variously performed.

For example, as shown in FIG. 2, a thread is formed on the outer circumferential surface of the first housing 111, a thread is formed on the inner circumferential surface of one end of the connecting hose so as to correspond to the thread of the first housing, Or a fastener (not shown) is provided on the outer circumferential surface of the first housing so as to protrude from the outer periphery of the first housing in the form of a band, and an end portion of the connecting hose is formed with an engaging groove in a band- And may be detachably coupled.

Next, a disk-shaped first blocking plate 112 having a diameter corresponding to the inner diameter of the first housing is provided in the first housing 111, and a predetermined length The first fixing pin 115 is formed.

In addition, a plurality of first ventilation holes 113 are formed on the first blocking plate in the radial direction with respect to the first fixing pin, and a first ventilation hole 113 is formed on the inside of the first blocking plate, A backflow prevention plate 114 is provided.

The first check valve 114 is opened to the first fixing pin 115 side by the pressure of the air flowing into the first housing 111 at the time of inhalation to open the first vent hole 113, So that filtered air (oxygen) is injected into the body.

When the air is blown out, the air returns to the original state (home position) by the pressure of the discharged air and is brought into close contact with the inner circumferential surface of the first blocking plate 112 to block the first ventilation hole 113, 300).

On the other hand, the first check valve 114 is smoothly opened through the pressure of the air, and when the pressure is removed, the first check valve 114 is returned to the initial state, And may be formed of a rubber material.

6 is an exemplary view of a second valve 120 according to an embodiment of the present invention.

The second valve 120 is provided with a cylindrical second housing 121 protruding outward so as to communicate with one side of the body.

The second housing 121 is formed into a cylindrical shape having a predetermined length so as to be straightly discharged to the outside without being scattered when the air is discharged through the second ventilation hole 123 by imparting straightness to the air discharged during exhalation.

In addition, a disk-shaped second blocking plate 122 having a diameter corresponding to an inner diameter of the second housing is provided in the second housing 121, and a second blocking plate 122 having a predetermined length The second fixing pin 125 is formed. In addition, on the second blocking plate, a plurality of second ventilation holes 123 forming air passages are formed in the radial direction around the second fixing pin, and on the outer side of the second blocking plate, And the second check valve 124 is fixed.

The second check valve 124 is in close contact with the second blocking plate 122 due to the pressure generated when the air is inhaled during the inspiration and blocks the second ventilation hole 123, And the second ventilation hole 123 is opened to smoothly discharge the air while being pushed toward the second fixing pin 125 due to the pressure generated when the air is expelled. It is possible to prevent the inner peripheral surface of the face portion or the body from being wetted or the glasses to be frozen.

Also, the second check valve 124 can be opened smoothly through the pressure of the air, and can be smoothly returned to the original state when the pressure is removed, For example, a rubber material.

The mask can vary greatly in breathability and breathability depending on the material.

For example, disposable masks woven with cotton fabrics made of cotton yarn have a problem in that since a plurality of voids are formed, air permeability is secured and respiration can be smooth, but fine particles and ultrafine dust are not filtered. In addition, when the wearer walks up the stairs or runs at a high speed, the mask is easily wetted and sticks to the face portion, which makes it difficult to breathe.

On the other hand, a dust-proofing mask made of a synthetic resin material, which is formed in a substantially cup shape for filtering a large amount of harmful dust such as a paper factory or a textile factory, is made of a dense woven structure in order to enhance the filtering effect. Therefore, there is a problem that breathing is not smooth when worn.

That is, the conventional mask has a problem that the filtering effect is relatively low when the breathability is excellent, and the breathability is low because the breathability is low when the filtering effect is excellent.

The present invention is characterized in that the body 100 having the first and second valves 110 and 120 opened and closed quickly according to the pressure of the air and the filter 300 having the air permeability are connected to each other through the connection hose 200 The filtered air is not lost and is supplied to the inside of the body 100 through the first valve 110 to enable smooth breathing and air blown out from the nose and mouth at the time of exhalation is supplied to the second valve 120 The first housing 111 and the second housing 121 are made of a cylindrical body having a predetermined length so that the air moves along the inside thereof It is possible to provide active oxygen and CO 2 emission, so that excellent air permeability and filtering effect can be expected.

The connecting hose 200 is a hose having a predetermined length which is coupled to the first valve 110 so as to communicate with one end of the first hose 200 and the other end of which is detachably coupled to one side of the filter 300, And is formed of a material having a predetermined elastic force.

In the present invention, the filter 300 is formed as an empty pocket or pouch, and may be made of a material having air permeability, for example, a cotton thread or a nonwoven fabric.

The filter 300 is detachably coupled to the other end of the connection hose 200 to communicate with the other end of the connection hose 200. A method of detachably coupling the filter 300 and the connecting hose 200 can be variously performed. For example, as shown in FIG. 2, the filter 300 and the connecting hose 200 can be detachably coupled through a screw connection.

In the conventional rectangular type disposable mask, since most of the inner circumferential surface except for the rim of the body is in close contact with the face portion at the time of wearing, the amount of air staying between the mask and the face portion is not sufficient. There is a problem that air supply is not performed and breathing is inconvenient.

In the present invention, the filter 300 may be formed into a pouch or a pouch having a predetermined size with air permeability to provide a sufficient amount of air filtered at the time of inhalation, so that breathing is not inconvenient.

Also, in the present invention, the filter 300 may comprise a portable or wearable configuration. For example, the filter may comprise a pouch having a sufficient area to cover a portion or the entirety of the chest, and a fixture (not shown) such as a shoulder strap or band for wearing the filter on both shoulders have.

As described above, when the filter 300 is put in close contact with the chest, it is worn by wearing a jacket, so that warm air can be inhaled relatively to the external temperature through the body temperature at the time of inhaling and the heat insulating effect of the clothes.

Particularly, in winter, if breathing is performed while a disposable mask of cotton cloth is worn in the winter, cold air from the outside flows in while passing through the mask, and relatively warm air is discharged through the mask at the time of exhalation, Is wet and becomes cold.

Since the warm air can be absorbed in comparison with the outside air, an effect of raising the body temperature can be expected, and since the path of inflow or outflow of air at the time of inhalation and exhalation is different, the inner circumferential surface of the body becomes damp The problem of wetting the face portion can be solved.

Next, as shown in FIG. 7, the present invention may include a fan 310 for blowing air filtered while rotating inside the filter to the body.

For example, the functional mask according to the present invention may be configured such that the fan 310 is normally turned off and then the fan 310 is operated when breathing is accelerated, such as walking uphill or running fast, thereby continuously supplying a larger amount of air, It is possible to secure property. In addition, when the fan 310 continuously supplies air, an air curtain is formed between the face portion and the body 100, so that foreign air including foreign matter or fine dust can be prevented from flowing into the inside of the body, There is an advantage that it can be further improved.

Although not shown in FIG. 7, a motor for driving the fan and means for supplying power (for example, battery) are further provided in the filter. When the fan 310 is provided in the filter 300, 1 valve, the air expelled at the time of exhalation is scattered by the air supplied through the fan 310 and is discharged naturally between the face and the body. Therefore, the face portion is wetted by the back flow phenomenon without the second valve, Can prevent the phenomenon.

As described above, according to the functional mask of the present invention, the air filtered through the filter is supplied to the body through the connection hose to suck the pleasant air, and in particular, prevents the air discharged during exhalation from flowing back through the second valve This makes it possible to prevent the face portion from becoming wet or frosty, and has the advantage of breathing through a sufficient amount of clean air filtered through a fan inside the filter.
