Background Technology

[0003] Generally, in public offices or financial institutions that perform public service duties, consultations are conducted face-to-face with many people, so if a person having a respiratory disease has a medical condition, pathogens can be transmitted through droplets generated during the consultation, so countermeasures are required.

[0004] In this regard, a droplet-blocking screen is installed at the public service counter, and the screen has a small opening at the bottom to allow small documents to be passed around. However, when relatively large items need to be delivered, they cannot be delivered due to the droplet-blocking screen, causing inconvenience in performing duties. In such cases, since the items must be delivered while facing the person in charge, there is a problem of exposure to disease infection. Additionally, droplets may adhere to the screen and cause infection due to bacteria contained in the droplets, so an effective sterilization method was required.

[0005] As an example of such a droplet blocking device, Korean registered patent No. 10-2178281 (registration date November 06, 2020) discloses a stand-type droplet blocking partition comprising: a rail having a rail groove cut along the longitudinal direction, which is mounted on the floor while extended to a certain length; and a partition panel standing upright at a certain height, which is detachably inserted into the rail groove.

[0006] However, the aforementioned conventional droplet-blocking partitions made it difficult to exchange documents or items during conversations and were not only a hindrance because they remained installed even when no visitors were present, but also had the problem of requiring separate sterilization work because they lacked a means to sterilize bacteria that could be contained in droplets generated during conversations.

FIG. 2 is a schematic exploded perspective view of the droplet blocking device of FIG. 1. FIG. 3 is a cross-sectional view of FIG. 1. FIG. 4 is a perspective view showing a state where the transparent screen is lowered in the droplet blocking device of FIG. 1. FIG. 5 is a cross-sectional view of FIG. 4. Specific details for implementing the invention

[0020] The present invention will be described in more detail below with reference to the accompanying drawings illustrating embodiments of the present invention.

[0021] In FIGS. 1 to 3, the droplet blocking device according to the present invention comprises a frame having a lower support member (1) fixedly installed on the floor and an upper support member (2) spaced upward from the frame, for example at desk height, a driving means for raising and lowering a droplet blocking plate between the upper and lower support members (1, 2) of the frame, and an LED module (10) for irradiating ultraviolet rays to the droplet blocking plate for sterilization. The droplet blocking plate may be formed as a transparent screen (7).

[0022] The above driving means comprises a motor (3) mounted in the center of the lower support member (1) of the transparent screen (7), a lead screw (4) mounted vertically between the upper and lower support members (1, 2) to rotate by the rotation of the output shaft of the motor, a movable block (5) screw-coupled to the lead screw and movable up and down according to the rotation of the lead screw, and a screen supporter (6) fixed to the movable block (5) and movable up and down together with the movable block to support the transparent screen. The screen supporter (6) is mounted on a guide block (9) provided to be movable on each of the guide rods (8) provided vertically between the ends on both sides of the upper and lower support members (1, 2).

[0023] A cover member (41) is provided on the outside of the lead screw (4) to prevent foreign substances or dust from adhering to the threaded portion of the lead screw and interfering with the up-and-down movement of the movable block (5) described later. The lead screw (4) is provided with a movable block (5) that is coupled to the lead screw and passes through a hole formed with a screw on its inner surface, allowing it to move up and down according to the rotation of the lead screw. The hole formed with a screw as described above refers to a female screw that is fastened to the lead screw (4). Here, the movable block (5) is attached to the screen supporter (6) in a form that accommodates the cover member (41) while being fastened to the lead screw (4) as shown in the drawing. Accordingly, the movable block (5) including the screen supporter (6) is installed in a structure in which movement is achieved by fastening the screw to the lead screw and both sides of the screen supporter (6) are simultaneously guided up and down by the guide rod (8), thereby enabling lifting and lowering. For reference, a normal rotating A movable body (here, referred to as a 'screen supporter' and a 'movable block') that moves along a lead screw is connected to the lead screw, and in order to reciprocate in a straight line left-right or up-down, the movable body is structured to move along at least one guide axis (here, referred to as a 'guide rod'). Accordingly, the movable block (5) is also fixed to a screen supporter (6) to which a transparent screen (7) is attached by a bracket (51), and moves up and down when the lead screw (4) rotates, so that the transparent screen (7) connected thereto moves up and down between the usage position and the storage position.

[0024] A horizontally bent horizontal section (61) is formed at the top of the screen supporter (6), and the horizontal section is bent upward to form a fixed section (62). The lower end of the screen (7) is positioned on the horizontal section (61) inside the fixed section (62), and the screen (7) is fixed to the screen supporter by fixing the screen (7) to the fixed section (62) using a bracket (63) with its lower end fixed to the horizontal section (61).

[0025] A rectangular opening (71) is formed at the bottom of the transparent screen (7) so that a petitioner can submit documents, etc. Additionally, an opening (72) in the shape of a trapezoid, for example, is formed at the top of the transparent screen (7) so that the top is open, and a holder (73) is fixed to the end of the opening (72). The holder (73) has a cross-section in the shape of a "C" so that, for example, a guide plate can be replaced and attached.

[0026] Additionally, the LED module (10) is installed on an upper support member (2) so as to be arranged toward a transparent screen (7) to irradiate ultraviolet rays onto the transparent screen, and includes a plurality of LED elements that irradiate ultraviolet rays having a sterilizing effect.

[0027] The LED elements of the above LED module (10) are configured to continuously irradiate ultraviolet rays to the same area of ​​the transparent screen (7) where the LED elements are raised and lowered for a time to obtain a sufficient sterilization effect by the ultraviolet rays generated from the LED elements. In particular, the vertical irradiation range of the LED elements of the above LED module (10) with respect to the transparent screen is configured to correspond to a vertical distance obtained by multiplying the distance traveled per second (cm / sec) of the transparent screen (7) during the time (sec) to obtain a sterilization effect.

[0028] For example, in order to obtain a sufficient sterilization effect of the LED elements, if the LEDs must be irradiated onto the transparent screen (7) for 3 seconds, and the moving speed of the transparent screen (7) by the moving block (5) is 2 cm / sed, the LED irradiation range by the LED elements must be 6 cm in the vertical direction. That is, when the LEDs are irradiated onto an area of ​​6 cm in the vertical direction of the transparent screen by the LED elements, ultraviolet rays are continuously irradiated onto the transparent screen (7) for 3 seconds, excluding the 6 cm area at the top and bottom ends, so a sufficient sterilization effect can be obtained on the surface of the transparent screen by the LED elements.

[0029] In this way, by controlling the motor so that the vertical distance of the irradiation area on the transparent screen according to the LED radiation angle of the LED element of the LED module (10) corresponds to the distance the transparent screen moves in the vertical direction by the lead screw driven by the motor during the time (sed) when a sufficient sterilization effect by ultraviolet light can be obtained on the transparent screen, the LED elements can irradiate the transparent screen for the time required for the sterilization effect, thereby enabling a sufficient sterilization effect to be obtained on the transparent screen.

[0030] In addition, considering the vertical movement speed of the transparent screen, the LED elements may be positioned at an angle relative to the transparent screen (7) on the upper support member (2) as needed to irradiate ultraviolet rays onto the vertical area of ​​the transparent screen for the required time for a sufficient sterilization effect.

[0031] This angle of inclination can be set by comprehensively considering the moving speed of the transparent screen (7) that moves up and down with the movable block (5) that moves by the motor as described above as an example, the LED radiation angle generated by the LED element, the sterilizing power of the LED element, and the LED irradiation time required for sterilization according to such sterilizing power.

[0032] The use of the droplet blocking device according to the present invention will be explained with reference to FIGS. 1, 3 and FIGS. 4, 5.

[0033] The droplet blocking device according to the present invention is installed in the lower space between, for example, a civil complaint consultation desk and a visitor desk, and the upper support (2) can be raised to a position adjacent to the bottom side of the desks, and at this time, the transparent screen (7) is installed so as to be raised through a gap between the desks or a hole formed in the boundary area between the desks.

[0034] As shown in FIGS. 4 and 5, at the storage position of the transparent screen (7), the movable block (5) linked to the lead screw (4) which is reverse-rotated by the motor (3), the screen supporter (6), and the transparent screen (7) are lowered, and are maintained in a lowered state until the bottom of the opening (72) of the transparent screen (7) is positioned to match the height of the desks.

[0035] Then, during an interview with a petitioner or counselor, as shown in FIGS. 1 and 3, the movable block (5) is raised in conjunction with the lead screw (4) which is rotated in the forward direction by the motor (3), and the screen supporter (6) coupled to the movable block and the transparent screen (7) installed on the supporter are raised, and the bottom of the rectangular opening (71) at the bottom of the transparent screen (7) is positioned so that it aligns with the surface of the desk, thereby allowing the counselor and the petitioner to exchange documents as needed.

[0036] As the transparent screen (7) moves from the lowered storage position of Fig. 4 to the raised usage position of Fig. 1, ultraviolet rays are irradiated by the LED elements of the LED module (10) to perform a sterilization action, thereby sterilizing bacteria contained in droplets that may be generated during conversation with a complainant and attached to the surface of the transparent screen (7).

[0037] In this way, the problem of disease infection caused by bacteria contained in droplets generated during conversations with visitors in public offices or financial institutions performing public service duties can be easily and effectively prevented by blocking droplets using a transparent screen serving as a rising and lowering droplet blocking plate of the droplet blocking device according to the present invention, and by effectively sterilizing the transparent screen to which droplets generated from the visitor during conversation adhere by irradiating ultraviolet rays onto the screen using an LED module during the rising and lowering process.
