Description

MASK

The present invention relates to a mask. More particularly, the present invention relates to a mask which is easy to carry and store, excellent in filtration performance due to a filter inserted therein, and does not cause discomfort like an ordinary mask so that men and women of all ages may routinely wear the mask safely and conveniently indoors and outdoors so as to prevent various respiratory infections such as a cold.

In general, masks are worn so as to protect respiratory organs or bronchial tubes from toxic substances in the atmosphere.

The masks may be classified into a special mask for use in special working environments where many toxic substances are generated, and an ordinary mask 100 made of a commonly used material, such as cotton.

However, the special mask is too expensive for an ordinary person to purchase. The ordinary mask 100 allows penetration of fine dust particles, for example, fine molecular particles contained in yellow dust or the like without collecting the fine dust particles, which makes the wearing of the mask 100 meaningless.

Therefore, The present invention has been made in an effort to solve the problems described above and an object of the present invention is to provide a mask which is easy to carry and store, excellent in filtration performance due to a filter inserted therein, and does not cause discomfort like an ordinary mask so that men and women of all ages may routinely wear the mask safely and conveniently indoors and outdoors so as to prevent various respiratory infections such as a cold.

In order to achieve the object described above, the present invention provides a mask including: a body; an air purifier coupled to or formed on the body and configured to purify and discharge air introduced therein; and a control unit coupled to or formed on the body, and configured to control an air volume of the air purified and discharged through the air purifier. The air purifier including: an air inlet through which the air is introduced; a filter unit including at least one filter configured to purify the air introduced through the air inlet; an insertion part into which the at least one filter is inserted; an air outlet through which the air purified by the filter unit is discharged; and a blowing fan configured to regulate air flow while being rotated so that the air introduced through the air inlet passes through the filter unit to be discharged through the air outlet. The control unit controls the rotation speed of the blowing fan depending on vibrations of the mask or an air volume of external air.

Meanwhile, an exemplary embodiment of the present invention provides a mask, in which the control unit includes: a vibration sensor configured to sense the vibrations of the mask; a counter unit configured to count the number of the vibrations sensed by the vibration sensor; and an air volume regulating unit configured to regulate the rotation speed of the blowing fan based on the counted number.

Further, an another exemplary embodiment of the present invention provides a mask, in which the control unit includes: an air volume sensor configured to sense an air volume of external air; and an air volume regulating unit configured to regulate the rotation speed of the blowing fan based on the air volume sensed by the air volume sensor.

The present invention described above provides a mask which is easy to carry and store, excellent in filtration performance due to a filter inserted therein, and does not cause discomfort like an ordinary mask so that men and women of all ages may routinely wear the mask safely and conveniently indoors and outdoors so as to prevent various respiratory infections such as a cold.

Characteristic features will be described with reference to FIGS. 2 to 4. As illustrated in these drawings, a mask 300 according to a first exemplary embodiment of the present invention includes a body 310, an air purifier 320 coupled to or formed on the body 310 and configured to purify and discharge introduced air, and a control unit 380 (see FIG. 7) configured to control air volume of the air purified and discharged through the air purifier 320.

The body 310 is formed of a synthetic resin substantially in an arc shape, and the air purifier 320 configured to purify and discharge the introduced air is formed at the center of the body 310.

The air purifier 320 may be fixedly coupled to the body 310 or removably coupled to the body 310.

Opposite ends of the body 310 may be formed in a bent shape or formed to be bendable.

The air purifier 320 includes an air inlet 326 through which the air is introduced, a filter unit 324 including at least one filter configured to purify the air introduced through the air inlet 326, an insertion part into which the at least one filter is inserted, an air outlet 328 through which the air purified by the filter unit 324 is discharged, and a blowing fan 322 configured to control the air flow while being rotated so that the air introduced through the air inlet 326 is discharged to the air outlet 328 through the filter unit 324.

In the first exemplary embodiment of the present invention, the air inlet 326 is formed on the bottom side of the air purifier 320, an filter insertion hole 325, into which the filter unit 324 is inserted, is formed on the rear surface, and the air outlet 328 is formed on the top side of the air purifier 320, in which the air introduced from the bottom side passes through the filter unit 324 inserted into the filter insertion hole 325 and enters the user's respiratory organs through the air outlet 328.

[0019] Here, in the filter unit 324 inserted into the filter insertion hole 325, different types of filters, for example, an ultra-fine wire mesh pre-filter and an antivirus HEPA filter are assembled so that the ultra-fine wire mesh pre-filter will filter relatively large dust particles or the like and the HEPA filter will filter fine dust particles, toxic viruses or the like.

In addition, a deodorizing filter configured to filter odors and musty smells of a toxic gas or the like, and a yellow dust filter configured to filter dust, nitrogen oxides, sulfur oxides or the like, which are generated when yellow sand storms occur, may be additionally coupled to the filter unit 324.

In addition, the body 310 is provided with a filter replacement notification unit 312 configured to make a notification regarding the filter replacement timing, in which the filter replacement notification unit 312 calculates the amount of time each of the filters has been used, the amount of time being stored in a memory, and when it is time to replace the filters, the filter replacement notification unit 312 makes a notification using a voice.

In addition, a dust sensor is provided in the air outlet 328 so that when a dust sensing signal enters the filter replacement notification unit 312 from the dust sensor, the filter replacement notification unit 312 makes a notification using a voice that it is time to replace the filters since the life of the filter unit 324 has come to an end.

The filter replacement notification unit 312 may make a notification on the filter replacement timing using light, sound, vibrations or the like.

In addition, an air guide unit 340 is coupled to the air outlet 328 to guide the air discharged through the air outlet 328 to enter the respiratory organs of the user who wears the mask 300.

That is, the air guide unit 340 is rotatably coupled to the air outlet 328 so that the air guide unit regulates the purified air to be suitable for the respiratory organs of the user who wears the mask 300 and then guides the purified air to enter the user's respiratory organs.

The body 310 is further provided with a power supply unit 360 configured to supply power to the air purifier 320, a switch unit 370 configured to be switched ON/OFF depending on whether to supply the power from the power supply unit 360 to the air purifier 320, and a light emitting unit 372 configured to emit light when the switch unit 370 is switched ON to supply the power.

Here, when the switch unit 370 is switched ON, the light emitting unit 372 emits light, and when the switch unit 370 is switched OFF, the light emitting unit 372 does not emit light.

The power supply unit 360 includes a battery 362 that supplies power to the air purifier 320 and a charging terminal 366 that charges the battery 362. The battery 362 and the charging terminal 366 may be formed on the body 310 or removably coupled to the body 310.

A pair of ear hook units 390 formed of rubber or a synthetic resin is provided on the body 310.

The ear hook units 390 may be fixed to the body 310 or removably coupled to the body 310.

The ear hook units 390 provided on the mask 300 may be formed by a hook-shaped synthetic resin material or a loop-shaped rubber material. When wearing the mask 300, the ear hook units 390 are put on the user’s ears to bring the mask 300 into close contact with the user’s face.

FIG. 5 is a perspective view illustrating a mask according to a second exemplary embodiment of the present invention, and FIG. 6 is a view illustrating a state of using the mask according to the second exemplary embodiment of the present invention;

Since the second exemplary embodiment of the present invention is the same as the first exemplary embodiment described above, except for an air purifier 320, only the configuration and function of the air purifier 320 will be described below.

Characteristic features will be described in detail with reference to FIGS. 5 and 6. The air purifier 320 includes an air inlet 326 through which air is introduced, a filter unit 324 including at least one filter configured to purify the air introduced through the air inlet 326, an insertion part into which the at least one filter is inserted, an air outlet 328 through which the air purified by the filter unit 324 is discharged, and a blowing fan 322 configured to regulate air flow while being rotated so that the air introduced through the air inlet 326 is discharged to the air outlet 328 through the filter unit 324.

In the second exemplary embodiment of the present invention, the air inlet 326 is formed on the front surface of the air purifier 320, the filter insertion hole 325 into which the filter unit 324 is inserted is formed on the top side of the air purifier 320, and the air outlet 328 is formed on the rear surface of the air purifier 320, so that the air introduced from the front side passes through the filter unit 324 inserted into the filter insertion hole 325 and the air purified thereby enters the user's respiratory organs through the air outlet 328.

Here, in the filter unit 324 inserted into the filter insertion hole 325, different types of filters, for example, an ultra-fine wire mesh pre-filter and an antivirus HEPA filter, are assembled so that the ultra-fine wire mesh pre-filter will filter relatively large dust particles or the like and the HEPA filter will filter fine dust particles, toxic viruses or the like.

At this time, when two or more filters are included in the filter unit 324, the same or different types of filters may be used.

Since the third exemplary embodiment of the present invention is the same as the first exemplary embodiment of the first exemplary embodiment described above, except for the control unit 380, only the configuration and function of the control unit 380 will be described below.

Characteristic features will be described in detail with reference to FIGS. 7 and 8. The body 310 includes a control unit 380 configured to control the air volume of the air purified and discharged through the air purifier 320, in which the control unit 380 is removably coupled to the body 310 so that the control unit 380 may be separated.

The control unit 380 controls the rotation speed of the blowing fan 322 included in the air purifier 320 so as to control the air volume of the air purified and discharged through the air purifier 320.

Reference numeral 381 denotes a cover that covers the control unit.

The control unit 380 includes a vibration sensor 384 configured to sense vibrations of the mask 300, a counter 386 configured to count the number of vibrations sensed by the vibration sensor 384, and an air volume regulating unit 382 configured to regulate the rotation speed of the blowing fan 322 based on the counted number of vibrations.

The vibration sensor 384 senses vertical vibrations when the user walks and transmits a sensed value to the counter 386.

At this time, the counter 386 senses the sensed vertical vibrations, i.e. the number of steps and transmits the count value to the air volume regulating unit 382.

The air volume regulating unit 382 regulates the rotation speed of the blowing fan 322 based on the counted number, and the discharged amount of the purified air is regulated depending on the rotation speed of the blowing fan 322. At this time, the rotation speed of the blowing fan may be regulated based on an accumulated count value of the vertical vibrations from a reference time, or on the basis of the counted number of vibrations per unit time.

That is, when the user walks slowly, the rotation speed of the blowing fan 322 decreases so that the discharged amount of air decreases, and when the user walks quickly, the rotation speed of the blowing fan 322 increases so that the discharged amount of air increases.

In addition, the control unit 380 includes an air volume sensor 388 configured to sense an air volume of external air, and an air volume regulating unit 382 configured to regulating the rotation speed of the blowing fan 322 based on the sensed air volume of the external air.

The air volume sensor 388 is positioned on the front surface of the mask 300 to sense the amount of wind that the user faces while walking and transmits a sensed value to the air volume regulating unit 382. The air volume sensor 388 is an instrument configured to measure the air volume by measuring wind speed or wind pressure and may be referred to as a wind speed meter or a wind pressure meter. The air volume sensor used in the present invention is not limited to a specific type.

The air volume regulating unit 382 regulates the rotation speed of the blowing fan 322 based on the air volume sensed from the outside and the discharged amount of the air is regulated according to the rotation speed of the blowing fan 322.

That is, when the air volume is small, the rotation speed of the blowing fan 322 decreases, and when the air volume is large, the rotation speed of the blowing fan 322 increases so that the discharged amount of the air increases.

The air volume regulating unit 382 may automatically regulate the air volume based on various sensor values. Alternatively, the rotation speed of the blowing fan 322 may be manually regulated step by step using the air volume regulating terminal.

The air volume regulating terminal may be switched between the automatic mode and the manual regulating mode where the intensity of the air volume is manually regulated step by step.

That is, when the air volume regulating terminal of the air volume regulating unit 382 is set to the automatic mode, the air volume may be regulated to be suitable for the user's environment, and when the air volume regulating terminal is set to the manual regulating mode, the intensity of the air volume may be regulated step by step.

The body 310 is further provided with a power supply unit 360 configured to supply power to the air purifier 320 and the control unit 380, a switch unit 370 configured to be switched ON/OFF depending on whether to supply the power from the power supply unit 360 to the air purifier 320 and the control unit 380, and a light emitting unit 372 configured to emit light when the switch unit 370 is switched ON to supply the power.

The power supply unit 360 includes a battery 362 that supplies power to the air purifier 320 and the control unit 320, and a charging terminal 366 that charges the battery 362. The battery 362 and the charging terminal 366 may be formed on the body 310 or removably coupled to the body 310. When the battery 362 and the charging terminal 366 are removably coupled, the battery 362 may be removed and charged using an external charging device.

In addition, the power supply unit 360 may include a solar cell device 364 provided on the front surface of the body 310 to supply the power to the air purifier 320 and the control unit 380. The battery 362 may be charged using the solar cell device 364.

The present invention configured as described above is operated in the following manner.

First, the mask 300 is worn to be in contact with the user's face so that the first support 332 is supported by the lower portion of the jaw, the second support 334 is supported by the front portion of the jaw, and the ear hook units 390 are hooked around the ears to be fixed.

Then, when the switch 370 provided on the body 310 is turned ON, power is supplied to the blowing fan 322 of the air purifier 320 so that the blowing fan 322 is rotated. The user may recognize that the air purifier 320 is operated, through the light emitted from the light emitting unit 372.

When the air purifier 320 is operated, the air introduced through the air inlet 326 formed in the air purifier 320 passes through the filter unit 324 to be purified, the purified air enters the user's respiratory organs through the air outlet 328 so that the user breathes in the purified air.

Here, the direction of the discharged air may be regulated by the air guide unit 340 such that the discharged air is directed toward the user's respiratory organs.

In addition, the air volume may be automatically regulated to be suitable for the user's environment by setting the air volume regulating terminal of the air volume regulating unit 382 to the automatic mode, or the intensity of the air volume may be regulated through the manual regulating mode.

Subsequently, when it is time to replace the filters while the mask 300 is worn and used, this is notified through a voice by the filter replacement notification unit 312, and the filters may be replaced according to the voice signal.

In addition, when a dust sensing signal is input to the filter replacement notification unit 312 from the dust sensor provided in the air outlet 328, the filter replacement notification unit 312 makes a notification using a voice that the life of the filter unit 324 has come to the end and it is time to replace the filters so that the filters may be replaced according to the voice signal.

In addition, when the battery 362 is discharged, the battery 362 may be charged using the battery charging terminal 366, or using the solar cell device 364.

As described above, a mask according to the present invention is easy to carry and store, excellent in filtration performance due to a filter inserted therein, and does not cause discomfort like an ordinary mask so that men and women of all ages may routinely wear the mask safely and conveniently indoors and outdoors so as to prevent various respiratory infections such as a cold.

In addition, the air volume regulating terminal of the air volume regulating unit may be set to the automatic mode so that the air volume may be automatically regulated to be suitable for the user's environment, or set to the manual regulating mode so that the intensity of the air volume may be regulated. Thus, the mask of the present invention is convenient to use.

Furthermore, when it is time to replace the filters, the filter replacement notification unit 312 makes a notification using a voice. Thus, the mask of the present invention is convenient to use.

Moreover, since the solar cell device is provided so that power may be supplied to the air purifier even if the battery is discharged, and the battery may be charged using the solar cell device. Thus, the mask of the present invention is convenient to use.

Although it has been described above that all components constituting an embodiment of the present invention are combined into a single unit or coupled to be operated as a single unit, the present invention is not necessarily limited to such an embodiment. That is, at least two elements of all structural elements may be selectively joined and operate without departing from the scope of the present invention. In addition, although each of the components may be implemented as an independent hardware, some or all of the components may be selectively combined with each other, so that they can be implemented as a computer program having one or more program modules for executing some or all of the functions combined in one or more pieces of hardware. Codes and code segments forming the computer program can be easily conceived by an ordinarily skilled person in the technical field of the present invention. Such a computer program may implement the embodiments of the present invention by being stored in a computer readable storage medium, and being read and executed by a computer.

In addition, since terms, such as "including," "comprising," and "having" mean that one or more corresponding components may exist unless they are specifically described to the contrary, it shall be construed that one or more other components can be included. All the terms that are technical, scientific or otherwise agree with the meanings as understood by a person skilled in the art unless defined to the contrary. Common terms as found in dictionaries should be interpreted in the context of the related technical writings not too ideally or impractically unless the present disclosure expressly defines them so.

Although the embodiments of the present invention have been described for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention. Accordingly, the embodiments disclosed in the present invention are merely to not limit but describe the technical spirit of the present invention. Further, the scope of the technical spirit of the present invention is limited by the embodiments. The scope of the present invention shall be construed on the basis of the accompanying claims in such a manner that all of the technical ideas included within the scope equivalent to the claims belong to the present invention.
