The main body 100 of the present invention has a top plate 110 and a side plate 120 made of a plate material (reference numerals not shown).

As long as the body 100 has a top plate 110 and a side plate 120 made of a plate material, the shape and structure of the bar are not limited, and a detailed description of the body 100 will be omitted.

However, the top plate 110 of the main body 100 includes a plurality of through holes 111 communicating with each of the inlets 211 formed on any one surface of the case 210 of the intake unit 200 described below, so that through holes ( 111), droplets and aerosol discharged from the user's respirator together with ambient air can be sucked into the intake unit 200 via the top plate 110.

Here, the through hole 111 may be formed from the upper surface of the upper plate 110 to the lower surface or may be formed from any one of the front, rear, and side surfaces of the upper plate 110 to the lower surface, as shown in FIG. By being inclined from the front end to the end, the inflow of air can be smoothed and the inflow of foreign substances can be suppressed.

In addition, the diameter of the through hole 111 gradually decreases as the distance to the first connection pipe 370 decreases, so that air is sucked through each through hole 111 regardless of the distance to the first connection pipe 370. The speed and flow rate can be relatively uniform.

In addition, the arrangement form of the through hole 111 formed in the upper plate 110 of the main body 100 is not limited.

That is, the through hole 111 may be arranged in various forms according to the shape and size of the top plate 110 of the main body 100, as shown in FIGS. 8, 9, and 10 .

On the other hand, the body 100 can be moved by rotation of the wheels by providing wheels (not shown in the drawing) at the lower ends of both side plates 120 .

The intake unit 200 of the present invention is disposed on the main body 100 and sucks droplets and aerosols discharged from the user's respiratory system along with ambient air through a plurality of inlets 211 formed on at least one surface of the box-shaped case 210. do.

At this time, the intake unit 200 is disposed on the main body 100, in particular, on the upper plate 110 of the main body 100 located closer to the user's breathing area, so that droplets and aerosols can be inhaled immediately upon discharge from the user's respiratory system. there is.

In addition, the inlet 211 formed in the case 210 of the intake unit 200 has a diameter gradually reduced as the distance to the first connection pipe 370 decreases, thereby reaching the first connection pipe 370. Regardless of the distance, the air intake speed and flow rate through each inlet 211 and through hole 111 can be relatively uniform.

On the other hand, in the intake unit 200, as the fan 320 of the purification unit 300 described below rotates and a suction force acts on the inside of the case 210, droplets and aerosols discharged from the user's respiratory tract along with the surrounding air are sucked in. this can be done

The purification unit 300 of the present invention filters and sterilizes air containing droplets and aerosol introduced through the first connection pipe 370 connected to the intake unit 200 .

At this time, the purification unit 300 includes a fan 320 rotating in one direction by driving a motor (reference numerals not shown); a filtering member 330 for filtering droplets and aerosols from the air sucked in by the suction force generated by rotation of the fan 320; A sterilization module 340 for sterilizing droplets and aerosols included in the air sucked by the suction force generated by the rotation of the fan 320; And a case 310 accommodating the fan 320, the filtering member 330, and the sterilization module 340; droplets and aerosols included in the air sucked into the case 310 by rotation of the fan 320.

In addition, the purification unit 300 further includes an input module 350 for injecting additives into the air, so that at least one of the additives, for example, oxygen, perfume, phytoncide, and fragrance is input by the input module 350 to the exhaust unit ( 400), more pleasant air can be discharged.

In addition, the purification unit 300 further includes a sensor 360 that detects at least one of droplets and aerosols contained in the air, infectious substances, fine dust, harmful substances to the human body, odor particles, and carbon dioxide, so that the sensor 360 signals As the fan 320 and the sterilization module 340 are operated by the fan 320 and the sterilization module 340, the degree of filtering and sterilization of the air passing through the purification unit 300 can be adjusted, so that droplets and aerosols, infectious substances, fine dust, harmful substances to the human body, Removal of at least one of odor particles and carbon dioxide may be smooth.

For example, when a relatively large amount of at least one of droplets and aerosols, infectious substances, fine dust, harmful substances to the human body, odor particles, and carbon dioxide is detected by the sensor 360, the operation time of the fan 320 and the sterilization module 340 and As the intensity increases, at least one of droplets and aerosols in the air, infectious substances, fine dust, substances harmful to the human body, odor particles, and carbon dioxide may be smoothly removed.

Here, air flowing by rotation of the fan 320 may have a velocity of 0.1-1.5 m/s affecting the user.

Also, in the purification unit 300, the case 310 includes the soundproofing pad 311 disposed along the inner surface, so that transmission of rotational noise of the fan 320 to the outside of the case 310 can be minimized.

At this time, the temperature and humidity control module 380 may have any conventional structure and method as long as it can control the temperature and humidity of the air inside the case 310, and a detailed description of the temperature and humidity control module 380 will be omitted.

Further, in the purification unit 300, the case 310 includes at least one opening 312 so that the filtered and sterilized air can be discharged to the outside through the opening 312 as well as to the opening 312. The connection between the first connection pipe 370 and the second connection pipe 420 to be described below can be made by this.

At this time, the first connection pipe 370 may be provided in plurality as shown in FIG. 7 .

Therefore, as the air is introduced through each of the plurality of first connection pipes 370, the air can be smoothly introduced into the purification unit 300.

That is, the first connection pipe 370 of the purification unit 300 may be a corrugated pipe, whereby the length of the first connection pipe 370 can be varied and bent.

On the other hand, since the purification unit 300 is disposed outside the main body 100, the filtered and sterilized air discharged from the purification unit 300 can be directly supplied to the outside of the main body 100, that is, the room where the main body 100 is disposed. there is.

Here, the purification unit 300 disposed outside the main body 100 may be connected to each intake unit 200 of the plurality of main bodies 100 .

Therefore, filtering and sterilization of droplets and aerosols included in the air introduced from each of the intake units 200 of the plurality of main bodies 100 can be performed with only one purification unit 300 .

In addition, the table (A) having a function of blocking air propagation of infectious diseases according to the present invention may further include an exhaust unit (400).

The exhaust unit 400 of the present invention discharges air containing filtered and sterilized droplets and aerosols introduced through the second connection pipe 420 connected to the purification unit 300 to the outside of the main body 100. .

Here, the diameter of the outlet 411 of the exhaust unit 400 is gradually reduced as the distance to the second connection pipe 420 decreases, so that each outlet port 411 has a diameter regardless of the distance to the second connection pipe 420. The air discharge rate and flow rate through 411 can be relatively uniform.

Such an exhaust unit 400 may be fixed to the side plate 120 of the main body 100 and the lower support plate 130 connected between one side plate 120 and the other, but is not limited thereto.

In particular, since the convection and vortex of the air discharged to the outside are minimized, the propagation of indoor infectious agents due to the convection and vortex can be suppressed.

When the exhaust unit 400 is fixedly installed on a separate board spaced apart from the top plate 110, air is discharged from the top to the bottom of the main body 100 through the exhaust unit 400, thereby forming vertical laminar flow. Horizontal movement of air, convection and vortex can be suppressed.

In addition, since one outlet 411 of the exhaust unit 400 fixed to a separate plate is disposed at an interval of 20-200 mm in front and rear or left and right, one of the outlets 411 adjacent to the exhaust unit 400 passes through each outlet 411 by the spaced interval. Interference in air discharge can be suppressed.

In addition, the outlet 411 of the exhaust unit 400, which is fixed to a separate plate, is formed intensively at the location where the user is located, so that the filtered and sterilized air discharged through the outlet 411 of the exhaust unit 400 is directed to the user. can be delivered smoothly.

In addition, the outlet 411 of the exhaust unit 400, which is fixed to a separate plate, is formed in a tubular shape as shown in FIG. 12, so that when air is discharged through the outlet 411, straightness is imparted to form vertical laminar flow. can be smooth

Here, the outlet 411 formed in a tubular shape is not limited in length, and may be formed in various lengths corresponding to the height of the exhaust unit 400 and the like.

In addition, the exhaust unit 400 fixedly installed on a separate plate includes a lamp 430 that is turned on when power is applied, so that the operating state can be displayed by turning on the lamp 430, and visibility is easily secured at night. can do.

In addition, the exhaust unit 400 fixedly installed on a separate plate includes a human body sensor 440 for detecting the presence of a user and the number of users, so that the purification unit ( 300) can be operated, and as the number of users increases, the operating intensity and operating time of the fan 320 and the sterilization module 340 of the purification unit 300 can be increased.

In addition, since the second connection pipe 420 of the exhaust unit 400 fixed to a separate plate material has a certain cross-sectional shape, the fixed height of the separate plate material can be adjusted by varying the length of the second connection pipe 420. can

On the other hand, when the table (A) having a function of blocking air propagation of infectious diseases according to the present invention further includes an exhaust unit 400, the purification unit 300 is disposed on one side of the main body 100, for example, the top plate 110 or It is disposed on the side plate 120.

The detailed description of blocking air propagation of infectious diseases through the table (A) having a function of blocking air propagation of infectious diseases according to the present invention is as follows.

Here, the upper plate 110 of the main body 100 includes a plurality of through holes 111 communicating with each of the inlets 211 formed on one side of the case 210 of the intake unit 200, and the through holes 111 As a result, droplets and aerosols discharged from the user's respiratory system can be sucked into the intake unit 200 through the top plate 110 together with the surrounding air.

Meanwhile, the distance between the inlet 211 formed in the case 210 of the intake unit 200 and the through hole 111 formed in the top plate 110 of the main body 100 to the first connection pipe 370 decreases. Accordingly, the air intake speed and flow rate through each inlet 211 and the through hole 111 can be relatively uniform regardless of the distance to the first connection pipe 370 because the diameter thereof gradually decreases.

In the present invention, the purification unit 300 is connected to the intake unit 200 through the first connection pipe 370.

Further, the purification unit 300 is disposed outside the main body 100, and the case 310 of the purification unit 300 includes at least one opening 312, so that filtered and sterilized air passes through the opening 312. ) Through the main body 100, it can be discharged to the outside, that is, supplied to the room where the main body 100 is disposed.

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

However, when a relatively large amount of air, droplets, and aerosols flow into the purification unit 300, filtering and sterilization may be insufficient.

However, in the present invention, the purification unit 300 includes a sensor 360 that detects at least one of droplets and aerosols, infectious substances, fine dust, harmful substances to the human body, odor particles, and carbon dioxide contained in the air. ), when a relatively large amount of at least one of droplets and aerosols, infectious substances, fine dust, harmful substances to the human body, odor particles, and carbon dioxide is detected, the operation of the fan 320 and the sterilization module 340 is performed according to the signal of the sensor 360. Since the operating time and intensity of the fan 320 and the sterilization module 340 are increased, filtering and sterilization of droplets and aerosols can be smoothly performed, as well as infectious substances, fine dust, harmful substances to the human body, odor particles, and carbon dioxide. Removal of at least one of them may be smooth.

In addition, the purification unit 300 may be connected to each intake unit 200 of the plurality of bodies 100 as shown in FIG. Filtering and sterilization of droplets and aerosols included in the air introduced from each unit 200 may be performed.
