Description

Device to block airborne transmission of infectious diseases

The present invention relates to a device for blocking airborne transmission of infectious diseases. More specifically, not only is the virus discharged from the user's respiratory tract inhaled, but the air that is filtered and sterilized after inhalation forms a vertical laminar flow in the direction of gravity and flows indoors. This relates to a device that blocks the airborne spread of infectious diseases that can smoothly block the airborne viral spread indoors as the probability of inhaling the virus indoors decreases through supply.

Recently, the incidence of infectious diseases such as coronavirus, which are diseases caused by pathogenic microorganisms transferring to living organisms and multiplying, has been increasing significantly.

At this time, one of the infection routes of infectious agents such as viruses or bacteria may be airborne.

Airborne transmission is when the infectious agent spreads through the air through droplets and aerosols discharged from an individual's nose and mouth to the respiratory tract of another person. To prevent the spread of infectious diseases, prevent the spread of droplets and aerosols discharged from a personal respiratory tract or use a personal respiratory tract. Filtering and sterilization of droplets and aerosols emitted from the system are required.

Accordingly, as recently disclosed in Korean Patent Publication No. 10-2021-0102033, the use of 'air conditioning devices' or 'air conditioning systems' that filter and sterilize indoor air or force ventilation is increasing.

However, general air conditioning devices or air conditioning systems are placed at a considerable distance from the user's breathing zone, and it takes a considerable amount of time to filter and sterilize droplets and aerosols by inhaling them after they are discharged from the personal respiratory system, so a certain amount of time is spent indoors. Since convection is inevitable, there is a risk that people indoors during the time when convection occurs will inhale droplets and aerosols containing infectious agents.

For the above reasons, attempts have been made to develop devices that enable inhalation close to a person's respiratory area and to supply filtered and sterilized air close to a person's respiratory area, but satisfactory results have not been obtained to date.

(Patent Document 1) Republic of Korea Patent Publication No. 10-2021-0102033

The present invention was proposed to solve the problems of the prior art as described above. Not only does the inhalation of viruses discharged from the user's respiratory tract occur near the user's respiratory area, but also the filtered and sterilized air is gravitated close to the user's breathing area. It forms a vertical laminar flow in the direction of action and is supplied indoors, thereby lowering the probability of the user and others other than the user inhaling the virus indoors, thereby providing an air transmission blocking device for infectious diseases that smoothly blocks airborne viral transmission indoors. There is a purpose to doing so.

In order to achieve the above object, the present invention,

In the device for blocking airborne transmission of infectious diseases according to the present invention, an intake unit, a purification unit, and an exhaust unit are arranged adjacent to the user's breathing area indoors, and the indoor ambient air sucked in by the intake unit and the droplets discharged from the user's respiratory tract are And as the aerosol passes through the purification unit, the droplets and aerosols contained in the air are filtered and sterilized, and the air filtered and sterilized in the purification unit is perpendicular to the direction of gravity action near the user's breathing area through the exhaust unit. Since it can be discharged forming a laminar flow, it can reduce the probability of the user and others other than the user inhaling the virus indoors, making it possible to smoothly block the airborne spread of the virus indoors.

In the device for blocking airborne transmission of infectious diseases according to the present invention, the intake unit, purification unit, and exhaust unit are arranged adjacent to the user's breathing area indoors, and can be especially placed on a moving object moving indoors, so it is more suitable for the user's breathing area. Air is sucked in from various points in the adjacent room, and filtered and sterilized air can be supplied to various points in the room closer to the user's breathing area, forming a vertical laminar flow in the direction of gravity, thus blocking viral airborne transmission indoors. It could be smoother.

At this time, the intake unit 100 inhales droplets and aerosols discharged from the user's respiratory tract along with the surrounding air as the fan 230 of the purification unit 200, which will be described below, rotates and suction force is applied to the inside of the case 110. This can be done.

In addition, the inlet 111 of the intake unit 100 is formed to have a gradually smaller diameter or a smaller number as the distance to the first connector 220 described below decreases, thereby reducing the number of inlets 111 to the first connector 220. ), the air intake speed and flow rate through each inlet 111 can be relatively uniform, regardless of the distance to the Inhalation can be done intensively.

In addition, the intake unit 100 is not limited in shape, and may be formed in various shapes as shown in FIG. 4 depending on the conditions of the installation site, etc.

Additionally, the intake unit 100 may be placed on a mobile body 10 that moves within the building by rotating the wheels 11.

Accordingly, the at least one intake unit 100 disposed on the mobile body 10 can inhale the droplets and aerodynamics discharged from the user's respiratory tract along with the surrounding air at various points inside the building.

At this time, the mobile body 10 includes at least one through hole 12 on at least one side that communicates with the inlet 111 of the intake unit 100, so that air containing droplets and aerosols passes through the through hole 12 and into the intake unit. It may flow into the inlet 111 of (100).

Here, the through hole 12 of the moving body 10 is formed to be inclined downward from the tip to the end, so that not only can the inflow of air be smooth but also the inflow of foreign substances can be suppressed.

Additionally, the intake unit 100 disposed on the mobile body 10 may be spaced apart from the surface of the mobile body 10 at the top or side by support of the first connection pipe 220, which will be described below.

Accordingly, the intake unit 100 is located closer to the user's breathing area, allowing smooth inhalation of droplets and aerosols discharged from the user's respiratory tract.

The purification unit 200 of the present invention is connected to the intake unit 100 and is connected to the intake unit 100. Droplets and Filter and sterilize air containing aerosols.

At this time, the purification unit 200 includes a fan 230 that rotates in one direction by driving a motor (not shown); A filtering member 240 that filters droplets and aerosols from the air sucked by the suction force generated by the rotation of the fan 230; and a sterilizing module 250 that sterilizes droplets and aerosols contained in the air sucked by the suction force generated by the rotation of the fan 230, thereby being included in the air sucked into the case 210 by the rotation of the fan 230. Droplets and aerosols may be filtered and sterilized while passing through the filtering member 240 and the sterilizing module 250.

Here, the filtering member 240 of the purification unit 200 may be of any type as long as it can filter droplets and aerosols contained in the air, and a detailed description of the filtering member 240 will be omitted.

And the sterilization module 250 of the purification unit 200 includes an ultraviolet lamp (not shown in the drawing) and a plasma generator (not shown in the drawing), thereby irradiating ultraviolet rays from the ultraviolet lamp and generating plasma from the plasma generator. Sterilization of contained droplets and aerosols can be achieved.

At this time, the ultraviolet lamp and plasma generator can be installed in any order.

In addition, the purification unit 200 further includes an input module 260 for injecting additives into the air, so that at least one of the additives, such as oxygen, perfume, phytoncide, and air freshener, is input by the input module 260, thereby causing the exhaust unit ( 300), more comfortable air can be discharged.

In addition, the purification unit 200 further includes an air inlet and outlet module 280, thereby increasing the amount of air inflow from the outdoor space into the case 210 and from the inside of the case 210 to the outside. Air discharge into the space, air inflow cycle, air discharge cycle, air inlet time, air discharge time, air inlet rate, and air outlet rate can be adjusted.

At this time, the air inlet and outlet module 280 includes an air inlet pipe 281 leading from the outdoor space to the case 210; An air discharge pipe 282 leading from the case 210 to the outdoor space: and a rotating fan 283 disposed in each of the air inlet pipe 281 and the air discharge pipe 282, thereby controlling the rotation of each of the rotating fans 283. As the rotation occurs, air from the outdoor space can be introduced into the case 210 through the air inlet pipe 281, and air can be discharged from the inside of the case 210 to the outdoor space through the air discharge pipe 282. there is.

In addition, the purification unit 200 further includes a sensor 270 that detects at least one of droplets and aerosols, infectious substances, fine dust, substances harmful to the human body, odor particles, and carbon dioxide contained in the air, thereby responding to the sensor 270 signal. As the fan 230, the sterilization module 250, and the air inlet and outlet module 280 operate, the degree of filtration and sterilization of the air passing through the purification unit 200, the inflow of external air and the outflow of internal air Since the degree can be adjusted, the removal of at least one of droplets and aerosols, infectious substances, fine dust, substances harmful to the human body, odor particles, and carbon dioxide can be smoothly removed.

For example, when a relatively large amount of at least one of droplets, aerosols, infectious substances, fine dust, substances harmful to the human body, odor particles, and carbon dioxide is detected by the sensor 270, the fan 230, the sterilization module 250, and the air intake and As the operating time and intensity of the discharge module 280 increases, the removal of at least one of droplets and aerosols, infectious substances, fine dust, substances harmful to the human body, odor particles, and carbon dioxide in the air can be smoothly removed.

In addition, the measurements of droplets and aerosols, infectious substances, fine dust, human harmful substances, odor particles, and carbon dioxide and oxygen concentrations detected by the sensor 270 are measured on one side or A display member (not shown in the drawing) provided externally may be displayed.

At this time, in addition to the sensor 270, the display member measures droplets and aerosols, infectious substances, fine dust, By displaying the measured values of substances harmful to the human body, odor particles, and carbon dioxide and oxygen concentrations, a comparison can be made between the measured values by the sensor 270 and the measured values by a separate sensor.

Additionally, the air flowing by the rotation of the fan 230 of the purification unit 200 may flow at a speed of 0.1-1.5 m/s in the user's breathing area.

In addition, the case 210 of the purification unit 200 includes a soundproofing pad 211 disposed along the inner surface, thereby minimizing the transmission of rotation noise of the fan 230 to the outside of the case 110.

In addition, the purification unit 200 further includes a temperature and humidity control module 290, so that the temperature and humidity of the air inside the case 210 can be controlled by the temperature and humidity control module 290.

At this time, the temperature and humidity control module 290 may be of any conventional structure and method as long as it allows the temperature and humidity of the air inside the case 210 to be controlled. Therefore, a detailed description of the temperature and humidity control module 290 will be omitted.

And the case 210 of the purification unit 200 includes at least one opening (not shown), so that the first connector 220 and the second connector 320 described below are connected by the opening. This can be done.

At this time, a plurality of first connection pipes 220 of the purification unit 200 may be provided.

Therefore, as air is introduced through each of the plurality of first connection pipes 220, air can be smoothly introduced into the purification unit 200.

And the first connection pipe 220 of the purification unit 200 may be a pipe with a certain cross-sectional shape.

Here, the tube having a certain cross-sectional shape may include at least one joint portion 221 as shown in FIG. 9 .

Accordingly, the first connector 220 may be bent by rotation of the joint 221.

Additionally, the first connection pipe 220 of the purification unit 200 may be a corrugated pipe.

Since the first connection pipe 220 of the purification unit 200 is a corrugated pipe, its length can be varied and curved.

Meanwhile, the purification unit 200 may be embedded in, attached to, or spaced apart from any one of the ceiling 1, wall 2, and floor 3 inside the building.

Therefore, it can be easy to connect the intake unit 100 and the purification unit 200, which are embedded in, attached to, or spaced apart from any one of the ceiling 1, wall 2, and floor 3 inside the building.

At this time, the purification units 200 spaced apart from one of the ceiling 1, wall 2, and floor 3 inside the building can be maintained in a spaced state by being supported by the support member 4.

And there are no restrictions on the arrangement form of the purification unit 200.

That is, the purification unit 200 may be placed adjacent to the intake unit 100, adjacent to the exhaust unit 300, or placed between the intake unit 100 and the exhaust unit 300, as shown in FIG. .

Additionally, the purification unit 200 may be placed on a mobile body 10 that moves within the building by rotating the wheels 11.

Accordingly, air containing droplets and aerosols flowing in from the intake unit 100 disposed on the mobile body 10 can be quickly filtered and sterilized by the purification unit 200.

The exhaust unit 300 of the present invention is installed connected to the purification unit 200, and air containing filtered and sterilized droplets and aerosols flows in through the second connection pipe 320 connected between the purification unit 200 and the purification unit 200. It is discharged to the outside through a plurality of outlets 311 formed on at least one side of the box-shaped case 310.

At this time, as the distance to the second connection pipe 320 decreases, the diameter of the outlet 311 of the exhaust unit 300 is gradually reduced or the number thereof is reduced, so that the outlet port 311 reaches the second connection pipe 320. Regardless of the distance, not only can the air discharge speed and flow rate through each outlet 311 be relatively uniform, but it is also concentrated at points where there are relatively many people, so that air is discharged at points where there are relatively many people. It can be done intensively.

Here, the outlet 311 of the exhaust unit 300 is formed in a tube shape, so that straightness can be provided when air flows through the outlet 311.

And the second connection pipe 320 of the exhaust unit 300 may be a pipe with a certain cross-sectional shape.

At this time, the pipe having a certain cross-sectional shape may include at least one joint portion 321 as shown in FIG. 9.

Accordingly, the second connector 320 may be bent by rotation of the joint portion 321.

Additionally, the second connection pipe 320 of the exhaust unit 300 may be a corrugated pipe.

Since the second connection pipe 320 of the exhaust unit 300 is a corrugated pipe, the length can be varied and curved.

In addition, the exhaust unit 300 includes a lamp 330 that lights up when power is applied, so that not only can the operating status be displayed by lighting the lamp 330, but visibility at night can also be easily secured.

In addition, the exhaust unit 300 includes a sensor 340 that detects the presence of a user and the number of users, so that the purification unit 200 can be operated only when the user is present according to the signal of the sensor 340. As the number of users increases, the intensity and time of the fan 230, sterilization module 250, and air inlet and exhaust module 280 of the purification unit 200 may be increased.

Meanwhile, the exhaust unit 300 may be embedded in, attached to, or spaced apart from any one of the ceiling 1, wall 2, and floor 3 inside the building.

Therefore, it can be easy to connect the purification unit 200 and the exhaust unit 300, which are embedded in, attached to, or spaced apart from any one of the ceiling 1, wall 2, and floor 3 inside the building.

At this time, the exhaust units 300 spaced apart from one of the ceiling 1, wall 2, and floor 3 inside the building can be maintained in a spaced state by being supported by the support member 4.

In particular, the exhaust unit 300 discharges air containing filtered and sterilized droplets and aerosols through the tube-shaped outlet 311, forming a vertical laminar flow in the direction of gravity, thereby preventing horizontal movement, convection, and eddy currents of indoor air. It can be suppressed.

Additionally, the exhaust unit 300 may be disposed on the mobile body 10 that moves within the building by rotating the wheels 11.

Therefore, the air containing filtered and sterilized droplets and aerosols flowing in from the purification unit 200 disposed on the mobile body 10 is discharged from the outside of the mobile body 10 by at least one exhaust unit 300 disposed on the mobile body 10. can be discharged as

At this time, the exhaust unit 300 disposed on the mobile body 10 may be spaced apart from the surface of the mobile body 10 at the top or side by support of the second connector 320.

Therefore, the formation height of vertical laminar flow by air discharge in the direction of gravity action through the outlet 311 of the exhaust unit 300, that is, the section of vertical laminar flow, can be maximized, thereby further increasing the horizontal movement, convection, and eddy currents of indoor air. It can be suppressed.

In addition, the exhaust unit 300, which is spaced apart from the surface of the mobile body 10, can be formed in various shapes, for example, either a plate shape or a cylindrical shape, as well as a parasol shape as shown in FIG. 10. It can be.

Here, the exhaust unit 300, which is formed in the shape of a parasol, has outlet ports 311 at intervals across the entire bottom of the case 310, as shown in FIG. 11, so that air flows in the direction of gravity action through the outlet port 311. The formation of vertical laminar flow by discharge can be smooth.

Meanwhile, the intake unit 100 and the exhaust unit 300 are formed so that their positions can be adjusted so that they can be placed close to the user's breathing area, thereby further minimizing the risk of spreading infectious agents.

Meanwhile, when the intake unit 100 or the exhaust unit 300 is installed spaced apart from the mobile body 10, the first connector 220 or the second connector 320 is connected to the intake unit 100 as shown in FIG. 12. ) Or, it can be connected to a position that can eliminate instability caused by leaning due to the weight of the exhaust unit 300, for example, it can be connected to the upper surface of the moving body 10 in a left-right symmetrical form.

At this time, the first connector 220 and the second connector 320 are rotatably connected to the mobile body 10, so that their positions can be varied according to the user's location and the conditions of the installation site as they rotate at the connection site. there is.

In addition, the mobile body 10 further includes an attachable support module 13 disposed on the bottom as shown in FIG. 13, so that the intake unit 100 or the exhaust unit 300 is supported by the support module 13. Instability caused by leaning due to weight can be resolved.

Here, the support module 13 can be rotated at the attachment site to vary its placement position in response to the user's location and the conditions of the installation site.

Meanwhile, a through hole (not shown) leading from the outside to the interior space is provided in the support module 13 and connected to the intake unit 100, so that intake can occur through the support module 13 as well as the intake unit 100. can be more smooth.

In addition, a cover (not shown in the drawing) that opens and closes the inlet 111 is provided on one side of at least one intake unit 100 installed in the mobile body 10, thereby blocking the opening of a portion of the inlet 111 through the cover. By doing so, intake can be smooth in the desired direction.

Blocking the airborne transmission of infectious diseases through the airborne transmission blocking device (A) for infectious diseases according to the present invention will be described in detail as follows.

The intake unit 100 of the present invention can be embedded in, attached to, or spaced apart from any one of the ceiling 1, wall 2, and floor 3 inside a building.

At this time, a plurality of inlets 111 are formed on at least one side of the case 110 of the intake unit 100, and the fan 230 of the purification unit 200 rotates to apply suction force to the inside of the case 110. Accordingly, droplets and aerosols discharged from the user's respiratory tract along with the surrounding air can be inhaled through the inlet 111.

Therefore, the probability that droplets and aerosols emitted from the user are spread to others indoors may be reduced.

And in the present invention, the purification unit 200 is embedded, attached, or spaced apart from any one of the ceiling 1, wall 2, and floor 3 inside the building, and is sucked in by the first connector 220. As it is connected to the unit 100, air containing droplets and aerosols sucked in by the intake unit 100 flows into the purification unit 200 through the first connection pipe 220.

At this time, the purification unit 200 includes a fan 230 that rotates in one direction by being driven by a motor; A filtering member 240 that filters droplets and aerosols from the air sucked by the suction force generated by the rotation of the fan 230; and a sterilizing module 250 that sterilizes droplets and aerosols contained in the air sucked by the suction force generated by the rotation of the fan 230. The inside of the case 110 is sterilized by the suction force generated by the rotation of the fan 230. Droplets and aerosols contained in the air inhaled can be filtered and sterilized in the process of passing through the filtering member 240 and the sterilizing module 250.

Here, the sterilization module 250 includes an ultraviolet lamp and a plasma generator, and droplets and aerosols contained in the air can be sterilized by ultraviolet irradiation from the ultraviolet lamp and generation of plasma from the plasma generator.

In addition, the purification unit 200 may further include an air inlet and outlet module 280. The air inflow amount from the outdoor space into the case 210 is calculated by the air inlet and outlet module 280, and the case 210 ) Air discharge, air inlet cycle, air outlet cycle, air inlet time, air outlet time, air inlet speed, and air outlet speed can be adjusted from the inside to the outdoor space.

At this time, the air inlet and outlet module 280 includes an air inlet pipe 281 leading from the outdoor space to the case 210; An air discharge pipe 282 leading from the case 210 to the outdoor space; and a rotating fan 283 disposed in each of the air inlet pipe 281 and the air discharge pipe 282. Each of the rotating fans 283 As the rotation occurs, air from the outdoor space can be introduced into the case 210 through the air inlet pipe 281, and air can be discharged from the inside of the case 210 to the outdoor space through the air discharge pipe 282. It can be done.

However, if a relatively large amount of air, droplets, and aerosols flow into the purification unit 200, filtering and sterilization may be insufficient.

However, in the present invention, the purification unit 200 includes a sensor 270 that detects at least one of droplets and aerosols, infectious substances, fine dust, substances harmful to the human body, odor particles, and carbon dioxide contained in the air. ), when at least one of droplets and aerosols, infectious substances, fine dust, substances harmful to the human body, odor particles, and carbon dioxide is detected in a relatively large amount, the fan 230, the sterilization module 250, and air intake according to the sensor 270 signal. and discharge module 280 are operated, and the operation time of the fan 230, sterilization module 250, and air inflow and discharge module 280 increases, so droplets and aerosols in the air, infectious substances, fine dust, Removal of at least one of human harmful substances, odor particles, and carbon dioxide can be smooth.

In addition, in the present invention, the purification unit 200 further includes an input module 260 for injecting additives into the air. At least one of additives, such as oxygen, perfume, phytoncide, and air freshener, is input by the input module 260. As a result, more comfortable air can be discharged through the exhaust unit 300.

In addition, in the present invention, the purification unit 200 may further include a temperature and humidity control module 290. As the temperature and humidity of the air inside the case 210 is controlled by the temperature and humidity control module 290, the indoor air quality is as a result. Temperature and humidity can be controlled to make indoor air more comfortable.

And in the present invention, the exhaust unit 300 is embedded, attached, or spaced apart from any one of the ceiling 1, wall 2, and floor 3 inside the building, and is purified by the second connector 320. When connected to the unit 200, air containing droplets and aerosols filtered and sterilized by the purification unit 200 flows into the exhaust unit 300 through the second connection pipe 320.

At this time, the exhaust unit 300 has a plurality of outlets 311 formed on at least one side of the box-shaped case 310, and air containing filtered and sterilized droplets and aerosols is discharged to the outside through the outlets 311. , In other words, it can be supplied to the room where the exhaust unit 300 is placed.

Therefore, as the user inhales the air discharged from the exhaust unit 300, the probability of inhaling the virus indoors may decrease.

Here, the exhaust unit 300 of the present invention discharges air containing filtered and sterilized droplets and aerosols through the tube-shaped outlet 311 in the direction of gravity, thereby forming a vertical laminar flow. Since the horizontal movement, convection, and eddy currents of indoor air can be suppressed, airborne transmission of infectious agents indoors can be minimized, further enhancing the quarantine effect.

As such, the device (A) for blocking the airborne spread of infectious diseases according to the present invention not only inhales viruses emitted from the user's respiratory tract near the user's respiratory area, but also directs the filtered and sterilized air near the user's respiratory area in the direction of gravity. It forms a vertical laminar flow and is supplied indoors, which can reduce the probability of the user and others other than the user inhaling the virus indoors, so it can smoothly block virus airborne transmission indoors and increase the quarantine effect.

Meanwhile, through the above description, the intake unit 100, purification unit 200, and exhaust unit 300 of the present invention are embedded in any one of the ceiling (1), wall (2), and floor (3) inside the building. , it may only be seen as being attached or spaced apart, but this is only an example. The intake unit 100, purification unit 200, and exhaust unit 300 of the present invention have wheels 11 as shown in FIGS. 6 and 7. ) It can be placed on the mobile body 10 that moves inside the building by rotation.
