Description

Mask with blower fan {MASK WITH BLAST FAN}

The present invention relates to a mask provided with a blower fan to facilitate breathing, and more particularly, to a mask having a blower fan installed to facilitate the flow of air through a filter membrane that filters air.

Unlike in the past, modern people are threatened with respiratory health by various harmful gases, yellow dust, and fine dust. This is a phenomenon that mankind is experiencing as we enter the era of industrialization, and air pollution is intensifying in proportion to the development of industry and the development of urban convenience.

The causes of air pollution are divided into natural, such as desert sandstorms and volcanic eruptions, and artificial, such as waste gas from factories and combustion of fuel.

In general, natural pollutants are generated by the physiology of nature and are temporary, so they do not pose a constant threat to human respiratory health. However, artificial pollutants are emitted from combustion of fuel, generation of nuclear energy using nuclear energy, chemical reactions, physical processes, automobiles, aircraft, etc. The main cause is various pollutants generated during fuel combustion, and human respiratory health has a lasting adverse effect on

Among them, carbon monoxide (CO), nitrogen dioxide (NO2), and sulfurous acid gas (SO2) occupy a high proportion. In particular, sulfur dioxide (SO2) reacts with other air pollutants to create additional secondary pollutants.

The carbon monoxide is a colorless, odorless, toxic gas that is generated when carbon in fuel is incompletely burned. Emission sources are mainly automobiles, and there are natural sources such as fuel combustion in factories and wildfires, and indoor sources such as kitchens, cigarette smoke, and district heating.

The nitrogen dioxide is a reddish-brown, highly reactive gas, generated by oxidation of nitrogen monoxide in the atmosphere, and acts as a precursor to generate ozone by reacting with volatile organic compounds in the atmosphere. The main sources of emission are automobiles, high-temperature combustion processes, and chemical manufacturing processes, and they are caused by natural phenomena generated by bacteria in the soil.

The sulfurous acid gas is a kind of sulfur oxide, it is a colorless, non-flammable gas that dissolves well in water and has a pungent odor. It exists in volcanoes and hot springs and reacts with hydrogen sulfide to produce sulfur. It is artificially emitted when fossil fuels such as coal and petroleum containing sulfur are burned, and the main emission sources are power plants, heating devices, metal smelters, oil refineries, and other industrial processes.

The air pollutants may be classified into gaseous materials such as sulfur dioxide and carbon monoxide and particulate materials such as dust according to particle sizes. In addition, depending on the production process, it is divided into primary pollutants and secondary pollutants.

Primary pollutants refer to substances that are released from the source and become pollutants as they are. For example, soot generated by the combustion of coal or petroleum, dust from cement factories, etc., sulfur oxides from automobile exhaust pipes, etc.

Secondary pollutants refer to those in which primary pollutants are produced as completely different substances through physical and chemical reactions in the atmosphere. An example of this is an oxidizing agent formed by the photochemical reaction of hydrocarbons and nitrogen compounds emitted from automobiles and factories, etc. by the ultraviolet rays of the sun.

On the other hand, ozone is a substance produced by a photochemical reaction between NOx and volatile organic compounds emitted into the atmosphere with ultraviolet rays, and belongs to secondary pollutants. Volatile organic compounds, which are precursors, are generated from various emission sources such as automobiles, chemical plants, and industrial facilities such as oil refineries and natural factors.

Currently, 61 types of air pollutants, including carbon monoxide, ammonia, nitrogen oxides, and sulfur oxides, have been designated as air pollutants. Among air pollutants, substances that may directly or indirectly harm human health, property, or the growth of animals and plants are designated as specific air pollutants. Currently, 35 species such as dioxin, benzene, carbon tetrachloride, and formaldehyde are designated as specific air hazardous substances.

In addition, yellow dust, dust wind, pollen, airborne bacteria, wildfires, and volcanic eruptions are also major causes of air pollution and threaten human health. In cities such as Beijing, China and Sumatra, Indonesia, visibility is lost for more than 30 days a year due to excessive consumption of fossil fuels and artificial wildfires for palm oil production, and even cities in neighboring countries are being damaged. It is impossible to walk the streets without wearing a mask.

In addition, air pollution at construction sites, cleaning sites, manufacturing plants, painting plants, hospitals, etc. is more serious. To avoid such polluted air, people wear face masks at industrial sites or sports activities. In addition, fires in buildings or facilities due to negligence or earthquakes, fires in automobiles or trains in tunnels, and toxic gases generated in agriculture or production sites can kill people immediately.

Recently, various attempts have been made to protect human respiratory health in such an environment, and one of them is the development of a mask. Since the main respiratory system of a person is the nose and mouth, it is to prevent direct inhalation of air pollutants by protecting the nose and mouth with a mask.

In the development of such a mask, the most important thing to focus on is airtightness. In other words, the goal should be to improve the technology to prevent external harmful substances such as fine dust and harmful gases from entering the inside of the mask.

However, the mask with improved sealing properties may interfere with the wearer's breathing. If you try on a mask that is commercially available, you can see that breathing is more difficult than you think. In particular, in the case of a mask made of cotton, it becomes more difficult to breathe when the moisture from breathing fills up and adheres to the nose or mouth.

Therefore, while improving airtightness, there is a need for a mask capable of inducing the wearer's breathing smoothly at the same time.

Republic of Korea Registered Utility Model No. 20-0422942 (published on Aug. 3, 2006) Republic of Korea Patent Registration No. 10-1925388 (Notice on Dec. 5, 2018) Republic of Korea Patent Registration No. 10-1930144 (Notice on Dec. 18, 2018) Republic of Korea Patent Publication No. 10-2018-0092363 (published on August 20, 2018)

Accordingly, it is an object of the present invention to provide a mask provided with a blower fan, which includes a blower fan that promotes the flow of air so that air can smoothly flow into the inside of the mask worn to suck air filtered by fine dust, etc. is doing

In order to achieve the object of the present invention described above, in one embodiment of the present invention, a front cover covering a portion of the wearer's face including the nose and mouth and having one or more ventilation holes formed therein, and installed on the rear surface of the front cover a filter unit for filtering air introduced from the outside through the ventilation hole of the front cover; There is provided a mask provided with a blower fan including a contact part installed along the perimeter of the ventilation part to seal the space between the ventilation part and the wearer's face.

According to the present invention, the space between the wearer's face and the mask is sealed so that only the air filtered with harmful substances can be sucked, and the difficulty of breathing is solved even when the air is sucked through the filter because the blower fan assists the suction power of the air. .

In addition, in the present invention, even if an external force such as wind acts, the external shape is not deformed, so the air, which is not filtered of harmful substances, does not flow into the wearer's respiratory tract.

In addition, since the present invention is provided with a separate discharge path so that the exhaled breath generated during respiration does not pass through the blowing fan, it is possible to prevent a problem in which noise is generated when the air introduced through the blowing fan collides with the exhaled breath.

And since the present invention can easily separate the detailed configuration, cleaning and replacement are convenient.

In addition, the charging terminal provides this to the blower fan 320 when electricity is supplied from an auxiliary battery or commercial power source through a USB cable or the like.

If necessary, the ventilation case 310 may have a first filtered air discharge hole (not shown) and a first sealing part (not shown) formed on the upper surface.

The first filtered air discharge hole is the air filtered by the filter 220 so that the air raised by the moisture blocking plate after being introduced by the blower fan 320 can be discharged in the upper direction of the ventilation case 310 . to form an exhaust passage; Accordingly, if the user uses the mask of the present invention as a necklace without wearing it on his face, or lays it on a desk so that the air exhaust passage of the close part is closed, it can be utilized as a portable air purifier.

The first sealing part is installed in the ventilation case 310 around the first filtered air discharge hole so as to open and close the first filtered air discharge hole, and manually open or close the first filtered air discharge hole in a slide manner. The first filtered air discharge hole is automatically opened and closed according to the control of the control module 330 . This first sealing part opens the first filtered air discharge hole so that the air that has passed through the filter unit 200 flows into the user's respiratory tract when the user uses the mask without wearing the mask on the face, and the user puts the mask on the face. When used in a worn state, the first filtered air discharge hole is closed.

The ventilation fan 320 constituting the ventilation unit 300 of the present invention is installed in the through hole 312 of the ventilation case 310, and when operated under the control of the control module 330, the front cover 100 and After inhaling air from the outside through the filter unit 200, the air is provided to the wearer's respirator. Since the blower fan 320 serves to suck external air through the mask instead of the wearer, the difficulty in which the wearer has to inhale air through the mask having a low porosity is resolved.

The exhaust hole is formed on the surface of the ventilation case 310, and forms a discharge passage for the wearer's exhalation so as not to collide with the air sucked from the outside by the blower fan 320. To this end, the exhaust hole communicates with the through hole 312 located on the rear surface of the ventilation fan 320 to ventilate the wearer's exhaled breath flowing in from the rear surface of the ventilation case 310 toward the through hole 312 of the ventilation case 310 . It is discharged to the outside of the case (310).

The opening 340 is installed in the ventilation case 310 to open and close the exhaust hole, and opens or closes the exhaust hole according to the control of the control module 330 . The opening 340 closes the exhaust hole so that air that has not passed through the filter unit 200 does not flow into the wearer's respiratory system when the wearer breathes in, and the air discharged to the outside of the wearer's body when the wearer breathes out is discharged through the exhaust hole The exhaust hole is opened to move to the outside of the mask through the

For example, the opening/closing opening 340 is installed in the ventilation case 310 and coupled to a driving device such as a motor connected to the control module 330, a rotating shaft connected to the driving device, and the rotating shaft depending on the rotation direction of the rotating shaft.

As a first embodiment, the control module 330 according to the present invention may be configured to control the blowing fan 320 so that the intake air amount of the blowing fan 320 is changed at intervals of a predetermined time.

For example, the control module 330 may control the blowing fan 320 so that the basic mode and the stop mode (or low-speed mode) are repeated at intervals of 1 to 3 seconds. At this time, the basic mode is a mode that helps the wearer to breathe by inhaling the external air at a predetermined capacity, the stop mode is a mode that stops the blowing fan 320 so as not to obstruct the wearer's exhalation, and the low speed mode is compared to the basic mode It is a mode for controlling the blowing fan 320 so that the air intake amount is 50% or less, preferably 10% or less. This low-speed mode is a mode in which the blowing fan 320 is operated at a low speed in order to block the moisture of the exhaled breath from flowing into the filter 220 through the blowing fan 320 .

As a second embodiment, the control module 330 according to the present invention may be configured to control the opening and closing ports 340 so that the opening and closing of the opening and closing ports 340 are repeated at intervals of a predetermined time. For example, the control module 330 may be configured to control the opening and closing port 340 so that the opening and closing of the exhaust hole are repeated at intervals of 1 to 3 seconds.

In this case, the control module 330 may control the blowing fan 320 so that the blowing fan 320 sucks in air at a certain level from the outside regardless of the opening or closing of the exhaust hole, and blowing according to the opening or closing of the exhaust hole. The blowing fan 320 may be controlled to interlock the operation of the fan 320 .

More specifically, if it is preset to link the operation of the blowing fan 320 according to the opening or closing of the exhaust hole, the control module 330 is the blowing fan 320 for 1 to 3 seconds to assist the wearer's breathing. is controlled in the normal mode, and the opening and closing port 340 is controlled so that the exhaust hole is closed for the same time as in the normal mode so that air that has not passed through the filter unit 200 is not introduced from the outside. Then, the control module 330 controls the blower fan 320 in the stop mode for 1 to 3 seconds to assist the wearer's exhalation, and stops the wearer's exhalation so that the exhalation passes through the exhaust hole instead of the filter unit 200. The opening 340 is controlled so that the exhaust hole is opened for the same time.

As such, when the blowing fan 320 is stopped when the wearer exhales, the collision between the air introduced from the outside by the blowing fan 320 and the wearer's exhalation does not occur, so the wearer's breathing is not disturbed, so exhalation is comfortable and noise generation due to vortex is prevented.

On the other hand, the ventilation unit 300 according to the present invention may be configured such that the first blowing fan 320 and the second blowing fan 320 are installed. The first blowing fan 320 may be installed in the through hole 312 of the ventilation case 310 for intake, and the second blowing fan 320 may be installed in the exhaust hole for exhaust. At this time, the control module 330 controls the first blowing fan 320 so that the first blowing fan 320 operates when the wearer breathes in, and the second blowing fan 320 operates when the wearer exhales. The fan 320 is controlled.

Referring to FIG. 4 , the fan mask according to the present invention may further include a breathing detection unit 600 .

The respiration sensor 600 collects data related to the wearer's inhalation and exhalation and provides the data to the control module 330. For this purpose, it is electrically connected to the control module 330 and faces the wearer's respirator. It is installed in the through hole of the ventilation case 310 that can.

At this time, the control module 330 analyzes the exhalation and inhalation based on the data received from the respiration detection unit 600, and controls the opening and closing port 340 to open and close the exhaust hole according to the breathing direction of the wearer.

More specifically, the control module 330 provides a closing signal to the opening 340 to close the exhaust hole when it is analyzed that the wearer is breathing in air based on the data received from the respiration detection unit 600, and , and provides a driving signal to operate the blowing fan 320 .

And when it is analyzed that the wearer is exhaling carbon dioxide based on the data received from the respiration detection unit 600, the control module 330 provides an opening signal to the opening 340 to open the exhaust hole. At this time, the control module 330 provides a stop signal for the blowing fan 320 to execute a stop mode, or executes a low-speed mode to the blowing fan 320 so that the air intake amount of the blowing fan 320 is lower than during inhalation. Provides a low-speed signal.

As such, when the wearer is exhaling, the air flowing into the filter unit 200 through the blower fan 320 is blocked so that moisture does not flow into the filter 220 and the electrostatic force of the filter 220 does not decrease.

As a specific aspect, the respiration sensing unit 600 according to the present invention is installed inside the ventilation unit 300 to detect a wind speed of the ventilation unit 300, or a wind speed sensor installed inside the ventilation unit 300 to detect the wind speed. It may be composed of a wind pressure sensor for sensing the wind pressure of 300, or both.

For example, the wind pressure sensor can detect a change in wind pressure inside the ventilation unit by analyzing the movement of the silicone rubber membrane linked by the pressure of exhalation.

If the control module 330 is configured to control the blowing fan 320 so that the blowing fan 320 is stopped according to the opening of the exhaust hole, the breathing detection unit 600 may not be provided.

Referring to FIG. 1 , the fan mask according to the present invention includes a contact part 400 .
