In relation to the air curtain device for blocking infectious diseases of the present invention, specific details will be developed with reference to the embodiments in the drawings.

In the drawing of FIG. 2, the present invention is arranged between people 30 facing each other across a table 20 or something in the form of a table 20 on which objects can be placed, and can be placed on the table 20. The form is taken so that

The present invention includes a main body 110; Control unit 120; and a blower 130; forming an air curtain with an air current 10 (wind, blowing) flowing upward from the bottom, through which, when people 30 face each other, the air is transmitted to the other person through the mouth and nose. It is provided to prevent the spread of disease by blowing away or blocking breathing, droplets, etc. with wind pressure (wind, air current (10)).

In addition, as shown in FIG. 4, the present invention can be used as an electric fan or blower by arranging a plurality of things in a row and adding a hinge part 140 that hinges between them, bending it on its axis and standing it upright.

In Figure 2, the main body 110 takes the shape of a box having a length, and the control unit 120 and the blower 130 are installed (built-in) in the empty space inside the box shape. The lower part 111 of the main body 110 is shaped so that it can be placed on the floor of a table 20 or the like.

To this end, the lower part of the main body 110 may have a flat shape, or may be provided with support protrusions 111a protruding outward and downward at four corners of the lower part, as shown in FIG. 2C.

The length of the main body 110 must be determined to provide a minimum blocking effect when people 30 face each other. For example, shoulder width may be a standard for length.

In addition, when a plurality of main body parts 110 are formed into one combination by tying them together with a hinge part 140, the total length of the plurality of main body parts 110 must meet the length standard of the main body part 110 described above. The individual length of each main body 110 can be determined by reducing it.

The control unit 120 controls the blower 130, and for this purpose, prior art may be cited. The control unit 120 supplies power from an external or built-in battery to the blower unit 130 and controls all operations of the blower unit 130, and includes a switch on the outside of the main body 110 so that the user can operate it. You can install buttons and configure remote control devices.

The control unit 120 can be configured together with the blowing unit 130 in one place to reduce the volume and facilitate the supply, replacement, and inspection after installation of parts, or can be configured separately and connected through conductors, etc. Please refer to the drawing example.

The blower 130 generates wind pressure and blows air upward along the length of the main body 110.

To this end, the blowing unit 130 may have a plurality of blowing blades, such as an inpeller or propeller, arranged in one or more rows along the length of the main body 110. At this time, the blowing blades are installed from the bottom upward, thereby creating a strong upward air current (10) to blow the droplets and breath of the patient infected with the disease to another place, preventing them from reaching the person they are facing.

As shown in the example below in Figure 5, the configuration of the blowing unit 130 is to install a separate air pressure generator 131, such as an air compressor, inside the main body 110, and install the length of the main body 110 on the upper part of the main body 110. This can also be achieved by installing a nozzle 132 that is disposed along and sprays upward. This configuration may refer to that of FIG. 1.

Figure 3 consists of two main body parts 110/(110a) (110b), and Figure 6 consists of three or more (four) main body parts 110/(110a) (110b) (110c) (110d). It has been accomplished.

3 and 6, two or more air curtain machines consisting of a main body 110 equipped with a control unit 120 and a blowing unit 130 are provided, arranged in a row, and then connected to each other to provide one. Bar, a hinge part 140 is formed between the main body parts 110 by connecting them with a hinge, so that the main body parts 110 can be folded or bent. Through the function of the hinge portion 140, the present invention can be used as an electric fan and can be conveniently carried and stored.

At this time, the control unit 120 may be configured in one of the plurality of main body units 110 and wired so that the remaining units can all be controlled together, or the control unit 120 may be individually configured in each main body unit 110. You can.

In this case, the hinge portions 140 of the main body 110 can be disassembled to provide a detachable configuration that can be used separately or combined.

In Figure 3, the air curtain machine is provided in a configuration in which both ends of the two main bodies 110/(110a, 110b) are hinged to each other. The end of one body portion 110a and the end of the other body portion 110b are brought into contact with each other and a hinge axis is placed on the surface of the end (or in the longitudinal direction of the end) to form a hinge coupling.

In other words, the hinge portion 140 is installed so that the hinge axis is positioned in the end direction (y, z) to achieve a hinge connection. The end directions (y, z) are the longitudinal direction of the main body 110, that is, a direction substantially perpendicular to the main body direction (x).

The example of the hinge portion 140 in FIG. 3 is provided in a horizontal end direction (y) parallel to the bottom 111 of the main body 110 or the bottom of the table 20.

The hinge portion 140 of FIG. 6 is provided in a vertical end direction (z) perpendicular to the bottom 111 of the main body 110 or the bottom of the table 20.

The hinge portion 140 can be arranged horizontally or vertically, and can be arranged in other inclined directions. The configuration of the hinge portion 140 may refer to the hinge of a swing door, etc.

Through this, the air curtain machine can provide functions in various aspects and forms by folding, bending, or unfolding the plurality of main body parts 110 with the hinge part 140 as the rotation axis.

For example, as shown in Figure 3B, either one of the main body parts 110a and the other main body part 110b can be rotated 180 degrees and folded completely to reduce the length by half (reduce the volume), making it easy to carry and store. there is.

Or, as shown in FIG. 4, one main body 110a and the other main body 110b are bent approximately 90 degrees around the hinge part 140 without folding both main bodies 110a and the other main body 110b. The air curtain device of the present invention can be erected by bringing the outer end (the end opposite the hinge portion 140) of the portion 110b (plural body portions 110/(110a, 110b)) into contact with the bottom of the table 20. ,

In this case, it can be used as a fan to cool off the heat by blowing the air current (10) in the direction of both front and back sides in approximately parallel rather than sending the wind upward, or as a blower that transports air in a horizontal direction. In this case, only one side can be turned on. there is.

In relation to the above, the drawing illustrates the case where the two main bodies 110/(110a, 110b) are folded in half to about 90 degrees and then stood up. In addition, the direction of the airflow 10 can be adjusted depending on the selection of the folding angle. You can choose.

At this time, in order to help the air curtain machine stand and stand, a non-slip member such as rubber is installed at the end opposite to the hinge portion 140 between the plurality of main body portions 110/(110a, 110b) (outer end of the main body portion). A standing support portion 111b configured to be attached may be added.

And, as shown in Figure 6, the hinge portion 140 is configured in the vertical end direction (z), and a plurality of hinge portions 140/(140a), 140b, and 140c are arranged in a zigzag manner so that each bends in a different direction, for example, in the opposite direction. When folded or folded, the air curtain machine main body (110)/(110a) (110b) (110c) (110d) can be folded laterally in a zigzag manner like a folding screen. Therefore, three or more body parts 110 can be connected and configured to be foldable.

As shown in Figure 7A, each of them is bent at approximately 90 degrees in opposite directions and stood erect, so that the wind can be blown in only one direction.

Even if the air curtain is still used for this purpose as shown in Figure 7 B, it can be placed flat on a table and surround a person to be protected, such as a staff member or patient. If this purpose is more important, the plurality of hinge parts 140 can be arranged on only one side rather than arranged in a jig.
