Description

Technology Field

[0001] The present invention relates to an immediate removal device for airborne bacteria and a method of operation thereof, which can remove airborne bacteria when aerosol bacteria are floating in an indoor space, and more specifically, can remove airborne bacteria by spraying a liquid or chemical solution that is slightly larger than the airborne bacteria toward the airborne bacteria so that the airborne bacteria are captured in the liquid or chemical solution and fall by gravity. Background Technology

[0002] Generally, when bacteria are airborne in restrooms or indoor spaces, aerosol bacteria smaller than 5 μm cannot fall due to gravity and remain suspended.

[0003] As a result, the problem arises where infectious bacteria spread through the air, leading to a higher transmission rate.

[0004] In particular, SARS and coronavirus have high transmission rates through airborne spread and high fatality rates upon infection, causing even greater public health problems.

[0005] Bacteria are classified into droplets and aerosols, and droplets refer to respiratory secretion liquid particles with a diameter larger than 5 μm, which settle to the surface of the earth under the influence of gravity when expelled from the human body.

[0006] And an aerosol refers to a respiratory secretion liquid particle with a diameter smaller than 5 μm. When expelled from the human body, before settling to the surface of the earth due to gravity, the moisture constituting the particle evaporates first, causing the diameter of the particle, which was smaller than 5 μm, to decrease further and thus change into a form that can be suspended in the air for a long time.

[0007] In this case, it can be seen that after the moisture in the particle has evaporated, the virus particles inside remain and exist suspended in the air.

[0008] This is also referred to as droplet nuclei.

[0009] As mentioned above, since airborne bacteria have very small particle sizes, a problem arises where their infectivity becomes very high when they float in the form of droplet nuclei formed by the evaporation of water.

[0010] In this regard, prior art document 1 (Registered Utility Model 20-0317757, Sterilization Device for Airborne and Drug-Resistant Bacteria) discloses a configuration comprising a first to third chamber (30-50) and a liquid tank (8) installed at the bottom thereof, which induces the proliferation of bacteria contained in the air and, during cell division, irradiates ultraviolet light through an ultraviolet lamp (3) to create a wound on the cell protective membrane of the bacteria, thereby penetrating copper ions and photocatalytic titanium oxide to more effectively sterilize bacteria inhabiting the air.

[0011] However, prior art 1 has a problem in that it cannot immediately remove airborne bacteria because it collects bacteria with a filter, multiplies them, and then sterilizes them using a ceramic filter and a UV lamp. Prior art literature

[0031] The present invention relates to an immediate removal device for airborne bacteria that can quickly remove airborne bacteria by capturing them and causing them to fall by gravity. In particular, it is characterized by being installed in areas at risk of contamination, such as restrooms or hospital rooms, and effectively preventing transmission by aerosolized bacteria by spraying a liquid or chemical solution toward bacteria floating in aerosol form to quickly capture and cause them to fall.

[0032] Hereinafter, an immediate airborne bacteria remover according to an embodiment of the present invention and a method of operation thereof will be described in detail with reference to the attached drawings.

[0033] FIG. 1 is an overall perspective view of an immediate floating bacteria remover according to an embodiment of the present invention, and FIG. 2 is an exploded perspective view of an immediate floating bacteria remover according to an embodiment of the present invention.

[0034] Referring to FIGS. 1 and 2, the present invention comprises a casing (100) installed on a wall of a zone at risk of airborne bacteria, such as a toilet, a liquid storage tank (200) built inside the casing (100) and storing a liquid sprayed toward the airborne bacteria, and an aerosol generating unit (300) provided on the front of the liquid storage tank (200) and generating the liquid stored in the liquid storage tank (200) into an aerosol form.

[0035] And it is configured to include a PCB board (400) installed inside the above casing (100) and equipped with a human entry detection sensor (410) to detect human entry and control the operation of the aerosol generating unit (300).

[0036] Here, the casing (100) is configured to include a front cover (110) provided facing the indoor space to spray an aerosol, and a rear cover (120) coupled to the front cover (110) and fixed to a wall.

[0037] And, in a state where the front cover (110) and the rear cover (120) are combined, a button operation hole (130) is formed to penetrate to one side and is configured to control by operating a button on the PCB board (400).

[0038] Additionally, the casing (100) is configured to include a substrate fixing part (140) that is provided in a shaft shape facing the inside of the front cover (110) and the rear cover (120) at the location where the PCB substrate (400) is installed to fix the PCB substrate (400), and a liquid storage tank fixing part (150) that is provided in a shaft shape facing the inside of the front cover and the rear cover at the location where the liquid storage tank (200) is installed to fix the liquid storage tank (200).

[0039] Meanwhile, the front cover (110) is configured to include an aerosol spraying unit (111) that sprays an aerosol-shaped liquid generated from the aerosol generating unit (300) toward the indoor space.

[0040] The above aerosol spraying unit (111) is formed to penetrate from the front cover (110) toward the indoor side, so that the aerosol generated from the liquid storage tank (200) can be sprayed toward the indoor side to capture airborne bacteria and cause them to fall.

[0041] At this time, the aerosol generating unit (300) may be equipped with an ultrasonic vibrator.

[0042] The ultrasonic vibrator generates fine vibrations at a high speed, so that the liquid is atomized into an aerosol form by the vibration and discharged toward the aerosol spraying unit (111).

[0043] And the lower part of the aerosol spraying unit (111) is configured to include a sensor detection unit (112) in which a human entry detection sensor (410) for detecting human entry is installed.

[0044] Here, the sensor detection part (112) has a sensor hole (112a) formed through it so that the human body entry detection sensor (410) is exposed, and a signal receiving groove (112b) is formed below it to guide the human body entry signal to be received by the human body entry detection sensor (410).

[0045] At this time, the sensor hole (112a) is provided to be inclined downward toward the indoor side, and the signal receiving groove (112b) is formed to be inclined in the opposite direction to correspond to the sensor hole (112a).

[0046] Meanwhile, the human entry detection sensor (410) mentioned above may be an ultrasonic sensor.

[0047] Accordingly, an ultrasonic signal is generated through the sensor hole (112a), and the reflected signal is received through the signal receiving home (112b), thereby increasing detection precision.

[0048] Additionally, the front cover (110) may be further provided with a deco panel (113) that can display a guide message or decorate the outside of the aerosol spraying part (111).

[0049] The above deco panel (113) is fitted or attached to the outside of the aerosol spraying unit (111) and can be used for purposes such as displaying a guide message for aerosol spraying or displaying an advertisement message, and can make the appearance of the casing (100) more aesthetically pleasing.

[0050] The above rear cover (120) has a wall fixing hole (121) formed on the upper part that is installed on the wall and fixed to the indoor wall, and a wall support protrusion (122) is provided on the lower part to support the casing (100) fixed by a nail or bolt through the wall fixing hole (121) so as to maintain a horizontal position.

[0051] The above liquid storage tank (200) is configured to include a tank cover (210) that is connected to the top of the liquid storage tank (200) while the liquid is stored, and protects the liquid while minimizing the exposed surface area.

[0052] Here, a liquid replenishment hole (211) is formed in the tank cover (210) through a central point, so that liquid can be refilled without opening the tank cover (210) or liquid storage container can be connected to the top to allow for continuous supply of liquid.

[0053] And it is configured to include a liquid level sensor (220) provided on the inner side of the tank cover (210) to detect the liquid level of the liquid stored in the liquid storage tank (200).

[0054] The above-mentioned liquid level sensor (220) is linked with the above-mentioned PCB board (400) to measure the remaining amount of liquid inside the liquid storage tank (200) in real time and transmit a signal to the PCB board (400), so that when the liquid is consumed below a certain level, the time to replenish the liquid can be notified to the manager through an alarm or communication function.

[0055] Meanwhile, on both sides of the liquid storage tank (200), a casing coupling part (230) is provided in the form of a bracket at a position corresponding to the liquid storage tank fixing part (150) provided in the casing (100) and coupled to the casing (100).

[0056] At this time, a bolt fixing hole (231) is formed in the casing coupling part (230) at a position corresponding to the liquid storage tank fixing part (150), so that it can be firmly fastened and fixed inside the casing (100).

[0057] FIG. 3 is a usage diagram illustrating the state in which an immediate airborne bacteria remover according to an embodiment of the present invention is installed on a wall.

[0058] Referring to FIG. 3, the wall fixing hole (121) has a circular lower portion and extends upward in an elongated slot shape. After installing a nail or bolt on the wall, the nail or bolt is passed through the wall fixing hole (121) to join it, and then lowered. The nail or bolt is caught in the slot-shaped groove and is firmly fixed so as not to be separated from the wall.

[0059] And the above wall support protrusion (122) supports the lower part of the casing (100) so that it is spaced apart from the wall, thereby enabling the casing (100) to be horizontally supported to correspond to the length of a bolt or nail.

[0060] As a result, the aerosol sprayer (111) is positioned at an accurate location toward the indoor side, and the spray distance is increased during aerosol spraying, thereby increasing the efficiency of removing airborne bacteria and enabling stable use.

[0061] FIG. 4 is an operation state diagram of an immediate airborne bacteria remover according to an embodiment of the present invention.

[0062] Referring to FIG. 4, the present invention is installed in an indoor space where there is a high possibility of airborne bacteria generation, such as a restroom, and is controlled by a PCB substrate (400) to spray a liquid in the form of an aerosol toward the indoor space.

[0063] Water can be used as the liquid, or chemical solutions harmless to the human body, such as alcohol-based disinfectants, may be used.

[0064] In this invention, when a person enters or exits a space in which a casing (100) is installed, the entry or exit is detected by a human body entry detection sensor (410), and a liquid is sprayed toward the room according to a set value.

[0065] Afterward, once the spraying is completed for the set time, the spraying operation stops and switches to a standby state.

[0066] As a result, by detecting the entry and exit of a user and spraying liquid for a set amount of time, it becomes possible to quickly remove airborne bacteria while the user is away.

[0067] FIG. 5 is a usage diagram showing the state in which an immediate airborne bacteria remover according to one embodiment of the present invention is fixed by a wall-fixing adhesive part.

[0068] Referring to FIG. 5, the casing (100) can be fixed by a wall-fixing adhesive part (500) without using bolts or nails.

[0069] The above wall fixing adhesive part (500) may be applied with a strength adhesive tape, and can be used by attaching it to a wall using the wall fixing adhesive part (500) in places where it is difficult to fasten nails or bolts.

[0070] FIG. 6 is a flowchart illustrating the operation method of an immediate airborne bacteria remover according to an embodiment of the present invention.

[0071] Referring to FIG. 6, when operation begins, the present invention maintains a standby state during the start phase, and when a user enters, the entry state is sensed for a certain period of time, for example, 1 second or more, to determine the entry of the user. When it is determined that the user has entered, the user state is switched to an entry state, and the operation of the entry / exit sensor is maintained while preparing and maintaining an operation state.

[0072] Alternatively, if user entry is not detected, the sensing state is maintained, and the process switches to the start phase to repeatedly perform the operation of detecting the entry status.

[0073] At this time, the input / output sensor may be a human body entry / exit detection sensor (410) with an ultrasonic sensor structure.

[0074] Afterwards, the user's exit is detected, and if it is determined that the user has been out of the sensor detection range for a certain period of time, for example, 2 seconds or more, the user status is switched to an exit state, and the operation of the entry / exit sensor is stopped.

[0075] Afterwards, liquid is sprayed according to a set time to capture airborne bacteria and cause them to fall.

[0076] Alternatively, if exit is not detected for a certain period of time or longer, it switches back to the entry state and is controlled so that the spraying operation is not performed.

[0077] Meanwhile, if the entry or exit of a human body is detected again while the spraying operation is being performed after the user is determined to have exited, the system switches the user status to an entry state and stops the spraying operation.

[0078] Also, if entry is not detected during spraying, the liquid is sprayed for a set amount of time, and the liquid spraying operation is stopped once the liquid has been sprayed for the set amount of time.

[0079] At this time, the method of operating an immediate airborne bacteria remover is characterized by determining that the user has exited and spraying a liquid when the user is not detected by the sensor for a certain period of time after leaving the sensor, and the ultrasonic detection distance is within 1M and does not detect distances greater than that.

[0080] In addition, the liquid spray can be set to spray for a set period of time, for example, in increments of 3 to 5 seconds, depending on the set value, and can also be set to repeat spraying the liquid for the set period of time after spraying the liquid for that period.

[0081] At this time, the number of repeated liquid cycles can be set differently depending on the environment.

[0082] The present invention, as described above, is installed in a space with a high possibility of transmission by airborne bacteria, such as a restroom or a hospital room, automatically detects the entry and exit of a user, and sprays a liquid or chemical solution toward bacteria floating in the indoor space in the form of aerosol to quickly capture them and cause them to fall by gravity, thereby immediately removing the airborne bacteria and preventing transmission by airborne bacteria.
