The effect of the present invention is to provide a non-sealed virus and bacteria blocking device that uses diamagnetic force and wind force to push droplets and aerosols away from the user's face to block the inflow of droplets and aerosols into the respiratory system and the spread of the user's droplets to the outside, as well as to sterilize viruses and bacteria contained in the droplets and aerosols by irradiating visible light sterilizing light that is harmless to the human body.

Description

[Technical field]

[0001] The present invention relates to a non-sealed virus and bacteria blocking device that does not block the mouth and nose, and more specifically, to a non-sealed virus and bacteria blocking device that can push droplets or aerosols containing viruses or bacteria out of the mouth and nose with diamagnetic force and wind force while the mouth and nose are open, and can sterilize the viruses and bacteria using a visible light germicidal lamp. [Background technology]

[0002] Generally, a mask is used to cover the nose and mouth to prevent the inhalation and dispersion of germs, dust, etc. for health and hygiene reasons.

[0003] In particular, masks are worn to prevent the spread of illnesses such as colds, and wearing them has become mandatory during the COVID-19 pandemic to prevent infection.

[0004] According to domestic and international quarantine authorities, related organizations and experts, including the US Centers for Disease Control and Prevention (CDC) and the World Health Organization (WHO), the main routes of transmission of COVID-19 can be divided into three categories: 1) airborne transmission by fine respiratory droplets and aerosol particles (airborne infection); 2) spray transmission by droplets (droplet infection); and 3) contact transmission by touching the nose, mouth, or eyes with contaminated hands (contact infection).

[0005] Specifically, airborne transmission is when the virus floats in the air in the form of aerosols, with particles smaller than 5μm or between 0.001 and 1μm in size, and is transmitted through the respiratory tract when other people breathe in the air. Aerosols are tiny droplets of water that do not sink but float in the air.

[0006] Droplet transmission is a form of infection in which viruses and bacteria are mixed in tiny droplets of saliva and other fluids that come out when an infected person coughs or sneezes, and enter the mouth or nose of another person. Droplets mean "droplets that fly and scatter," and the size of droplets is 5 to 10 μm. Generally, when a person coughs once, about 3,000 respiratory droplets are sprayed within 2 meters in front of them and fall, killing the virus. When droplets are 5 μm or smaller in size, they are called droplet nuclei.

[0007] Therefore, to avoid airborne and droplet infection, it is better to stay at least 2m away from an infected person and wear a mask.

[0008] However, because masks seal the mouth and nose, they must be removed when eating, leaving people exposed to droplets and aerosols from others.

[0009] In addition, even when wearing a mask, it does not fit completely or seal tightly, and gaps may occur between the face and the mask due to facial movements, etc., which can cause the risk of other people's droplets or aerosols flowing in through the gaps when breathing.

[0010] Furthermore, there was a problem in that it was difficult for infants, people with brain lesions, developmental disorders, and patients with respiratory disorders to wear masks. [Prior art documents] [Patent documents]

[0032] The advantages and features of the present invention, and the method for achieving the same, will become apparent from the following detailed description of the embodiments in conjunction with the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below, and may be embodied in various different forms, and the embodiments are provided to fully disclose the present invention and fully inform those skilled in the art of the scope of the invention, and the present invention is only defined by the claims. The same reference numerals refer to the same elements throughout the specification.

[0033] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described with reference to the drawings for explaining a non-sealed virus and bacteria blocking device according to an embodiment of the present invention.

[0034] Referring to FIG. 1, the non-sealed virus and bacteria blocking device according to the present invention includes a body 10 and a blocking part 20 .

[0035] First, the main body 10 is formed so as to be detachable from the user's body.

[0036] For example, the body 10 may be formed into a "C" shape with one side open and worn around the user's neck.

[0037] In this case, the main body 10 may be hung around the neck with both ends positioned at the clavicle of the user, or may be fixed around the neck or resting on the shoulder. The main body 10 may be provided with a length adjuster that can adjust the length of both ends so that the part where the main body 10 is rested on the neck or shoulder can be adjusted according to the user's body structure or size.

[0038] The middle portion of the main body 10 may have elasticity so that the two ends can return to their original state after being expanded.

[0039] The body 10 of the non-sealed virus and bacteria blocking device according to the present invention may be formed in a band shape with one side open and worn around the neck or shoulders, and may have blocking parts 20 on both ends.

[0040] For example, the main body 10 may be formed into a "C"-shaped neckband that can be worn around the neck or shoulders. As another example, the main body 10 may be formed into an "O" shape to be placed on the head, or may be formed into a peg or ring shape to be fixed to the user's clothing, etc., and may be formed into various shapes without being limited thereto.

[0041] A power supply unit 40 may be provided inside the main body 10 to supply power for driving the circuit breaker 20, which will be described later. At this time, the power supply unit 40 may be provided inside the circuit breaker 20, which will be described later, or may be a rechargeable battery. A charging port 11 may be formed on the outside of the main body 10 and electrically connected to the power supply unit 40 so that the power supply unit 40 can be charged by an external power source.

[0042] Here, the charging port 11 may be formed as a micro 5-pin, a lightning 8-pin, a USB C type, or the like, but is not limited thereto.

[0043] The blocking unit 20 is provided in the main body 10 and blocks droplets or aerosols from entering the respiratory tract of the user. That is, the blocking unit 20 can push droplets or aerosols away from the respiratory tract of the user or sterilize them.

[0044] Also, the blocking portion 20 may be provided at both ends of the body 10 formed in a "C" shape and rotatably provided.

[0045] In other words, since each user has a different body size and structure, the blocking portion 20 is adjusted so that it faces the user's respiratory system when the main body 10 is worn around the neck or shoulders, thereby pushing out or sterilizing droplets or aerosols around the user's respiratory system.

[0046] Here, the blocking unit 20 may be provided with a magnetic unit 21, an air supply unit 24, and a light irradiation unit 29, which will be described later, on the body 20a.

[0047] Here, the non-sealed virus and bacteria blocking device of the present invention may further include an angle adjustment unit 30.

[0048] The angle adjusting unit 30 connects the main body 10 and the blocking unit 20, and can be rotated or bent in the front-rear and left-right directions to adjust the angle so that one side of the blocking unit 20 faces the respiratory system of the user. The magnetic part 21 and the air supplying part 24 of the blocking unit 20, which will be described later, can be rotated or bent by the angle adjusting unit 30 to adjust the angles of the magnetic field direction and the air supplying direction.

[0049] For example, the angle adjusting unit 30 may be configured such that the main body 10 and the blocking unit 20 are connected with a ball joint type fastening structure. Referring to Figs. 2 and 3, a protruding ball 31 may be formed on the main body 10, and the ball 31 may be fitted into the other side of the blocking unit 20 to form a fitting groove 32 that rotates forcibly. That is, the blocking unit 20 can be moved freely to change the direction and angle that one side of the blocking unit 20 faces, and the blocking unit 20 is coupled to rotate forcibly, so that the adjusted direction and angle can be firmly maintained against external vibrations and impacts.

[0050] In addition, the angle adjustment unit 30 may be made of a bending member made of a material such as metal that can maintain a bent state when bent. The angle adjustment unit 30 may be made of a joint part that is connected by a number of joints and can be bent, or may be made of a hinge structure.

[0051] As described above, the angle adjusting unit 30 may have various structures capable of adjusting the direction and angle of one side of the blocking unit 20 and fixing it in the adjusted state.

[0052] Meanwhile, referring to Figures 4 to 7, the blocking unit 20 may include one or more of a magnetic unit 21, an air supply unit 24, and a light irradiation unit 29 so as to block droplets or aerosols from entering the user's respiratory system.

[0053] First, the magnetic unit 21 can generate a magnetic field in the respiratory system of the user, so that a diamagnetic force is generated in droplets or aerosols.

[0054] At this time, the droplets or aerosols consist of water droplets, which generate diamagnetic forces in response to the magnetic field.

[0055] Here, diamagnetism refers to the phenomenon in which the direction of magnetization is opposite to the direction of the magnetic field when a magnetic field is applied to a material. Representative diamagnetic materials include gases and water, excluding metals and oxygen.

[0056] In other words, droplets or aerosols are made up of water droplets floating in the air, and when a magnetic field is applied from the magnetic part 21, they are pushed in a direction opposite to the direction of the magnetic field.

[0057] In addition, the magnetic unit 21 is rotatably provided on the main body 10 so that the direction of the magnetic field can be adjusted. At this time, the magnetic unit 21 can be forcibly rotated on the main body 10 to adjust the direction of the magnetic field, and can be fixed in the adjusted state.

[0058] In other words, when the angle of the magnetic part 21 is adjusted so that the direction of the magnetic field is directed toward the user's respiratory system, the magnetic field direction is set to the user's respiratory system, so that droplets or aerosols around the user's respiratory system are pushed away from the user's respiratory system by the diamagnetic force, thereby preventing the user from becoming infected with viruses and bacteria.

[0059] Meanwhile, the magnetic part 21 may be formed to protrude in the direction of the magnetic field. That is, the magnetic part 21 may be formed to protrude from one side of the body 20a of the blocking part 20 and may be provided rotatably.

[0060] In this case, the magnetic portion 21 may be an electromagnet consisting of a plunger and a coil 23 wound around the plunger, or a permanent magnet, but is not limited thereto.

[0061] In addition, the coil 23 of the magnetic unit 21 is electrically connected to the power supply unit 40. Thus, the magnetic unit 21 can apply a magnetic field to the droplets or aerosol depending on whether or not the power supply unit 40 applies power.

[0062] In addition, the magnetic portion 21 may be formed with a cover 28 that surrounds the plunger and the coil 23 .

[0063] Meanwhile, the blocking unit 20 may further include an air supply unit 24 .

[0064] The air supply 24 can supply air to the user's respiratory tract to push droplets or aerosols away from the respiratory tract.

[0065] At this time, the air supply unit 24 may include a motor 26 that receives power from the power supply unit 40 to rotate a shaft 25, and a fan 27 coupled to the shaft 25. The fan 27 may exhaust air to one side of the blocking unit 20. At this time, the motor 26 is illustrated as being provided inside the blocking unit 20, but it may be provided inside the main body 10. Also, an exhaust port 27a may be formed on one side of the body 20a and an inlet port may be formed on the other side so that external air can be introduced into the blocking unit 20 and exhausted by the rotation of the fan 27.

[0066] Also, the air supply unit 24 may be rotatably provided on the main body 10. This allows the air supply direction to be adjusted.

[0067] That is, the direction of the air supply can be adjusted to be directed toward the user's respiratory system depending on the structure and size of the user's body.

[0068] Here, the drawings of the non-sealed virus and bacteria blocking device according to the present invention show that the air supply unit 24 and the magnetic unit 21 are provided together in the body 20a of the blocking unit 20, but this is not limited to this, and a first blocking unit provided with the magnetic unit 21 or the air supply unit 24, and a second blocking unit provided with the air supply unit 24 or the magnetic unit 21 may each be provided in the main body 10.

[0069] In this case, when it is divided into a first blocking part and a second blocking part, each of them can be rotatably provided on the main body 10 to adjust the magnetic field direction and the air supply direction, respectively. Also, the first blocking part can be rotatably provided on the main body 10, and the second blocking part can be rotatably provided on the first blocking part.

[0070] In addition, since the magnetic part 21 and the air supply part 24 push the droplets or aerosols around the user's respiratory system to the outside of the user's respiratory system, the user can adjust the magnetic field direction of the magnetic part 21 and the air supply direction of the air supply part 24 from behind the user to the front direction or diagonal direction, etc.

[0071] The magnetic field of the magnetic section 21 can serve to push out small aerosols, and the air of the air supply section 24 can serve to push out droplets and aerosols that are larger than the aerosols, but is not limited to this.

[0072] On the other hand, the blocking section 20 may further include a light irradiating section 29 .

[0073] The light irradiating unit 29 can irradiate the respiratory tract of the user with visible germicidal light to sterilize viruses and bacteria contained in droplets or aerosols.

[0074] Visible light is electromagnetic radiation with wavelengths in the range of 380 to 780 nm (nanometers) that can be perceived by the human eye. Wavelengths above 780 nm are infrared rays and heat rays used in radio waves, while wavelengths below 380 nm are ultraviolet rays, x-rays, etc.

[0075] At this time, visible light with a wavelength of 405 nm can react with oxygen to produce active oxygen that is harmless to the human body, and can kill 99.9% of harmful bacteria such as Escherichia coli, Staphylococcus aureus, pneumonia bacteria, and antibiotic-resistant bacteria (MRSA).

[0076] The sterilization principle of visible light with a wavelength of 405 nm is that it reacts with porphyrin in bacteria and other organisms to produce active oxygen, which destroys bacteria and viruses.

[0077] That is, the visible light sterilizing light has a wavelength of 405 nm, which is not harmful to the human body like ultraviolet light, and can be directly irradiated onto the human skin. This allows the light irradiating unit 29 to sterilize viruses and bacteria contained in droplets or aerosols floating around the user's respiratory tract.

[0078] In addition, the light irradiator 29 may be provided at the outlet 27a or the inlet of the air supply unit 24 so as to sterilize the external air introduced by the fan 27 of the air supply unit 24 or to sterilize the exhausted air. In addition, the light irradiator 29 may be provided on one side of the shielding unit 20 provided with the light irradiator 29, and the shielding unit 20 may be rotated or bent to adjust the irradiation direction of the sterilizing light from the light irradiator 29.

[0079] Here, the non-sealed virus and bacteria blocking device of the present invention is shown in the drawings as having the air supply unit 24, the magnetic unit 21 and the light irradiation unit 29 all provided in the body 20a of the blocking unit 20, but is not limited to this and may be provided in the main body 10 as a first blocking unit provided with the magnetic unit 21 or the air supply unit 24, a second blocking unit provided with the air supply unit 24 or the magnetic unit 21, and a third blocking unit provided with the light irradiation unit 29, and the light irradiation unit 29 may be provided in the first blocking unit or the second blocking unit, or may be provided in the main body 10, so is not limited to this.

[0080] In addition, since it is efficient to sterilize the surroundings of the user, a plurality of light irradiating units 29 may be provided along the length of the main body 10, and a plurality of light irradiating units 29 may also be provided in the blocking unit 20.

[0081] Furthermore, when the magnetic part 21, the air supply part 24 and the light irradiation part 29 are provided integrally, the magnetic field direction of the magnetic part 21, the air supply direction of the air supply part 24 and the sterilizing light irradiation direction of the light irradiation part 29 can be arranged so as not to interfere with each other.

[0082] 7, the user can adjust the angle of the blocking part 20 while wearing the main body 10 around the neck and shoulders. At this time, since the angles of the magnetic part 21 and the air supply part 24 can be adjusted separately, the magnetic field direction and the air supply direction can be adjusted to be different from each other.

[0083] Meanwhile, referring to FIG. 8, the non-sealed virus and bacteria blocking device of the present invention may further include a control unit 50 and an operation unit 60.

[0084] The control unit 50 can control whether the magnetic unit 21, the air supply unit 24, and the light irradiation unit 29 are operated or not.

[0085] The control unit 50 can also control two or more of the magnetic unit 21, the air supply unit 24, and the light irradiation unit 29 to operate simultaneously.

[0086] The operating unit 60 is provided in the main body 10 or the blocking unit 20 and can input activation signals for the magnetic unit 21, the air supply unit 24, and the light irradiation unit 29.

[0087] For example, the operation unit 60 may include a power button 61, a main function button 62, and adjustment buttons.

[0088] The power button 61 can input an actuation signal that can turn on / off the power supply unit 40. At this time, the actuation signal can be input when the power button 61 is pressed and held down to turn on / off the power supply unit 40.

[0089] In addition, the main function button 62 can input an operation signal to operate any one of the preset magnetic unit 21, air supply unit 24, and light irradiation unit 29. At this time, when the main function button 62 is pressed once, an operation signal for the magnetic unit 21 is input, when it is pressed twice or pressed twice consecutively, an operation signal for the air supply unit 24 can be input, and when it is pressed three times or pressed three times consecutively, an operation signal for the light irradiation unit 29 can be input.

[0090] In addition, when the main function button 62 is operating one or more of the magnetic unit 21, the air supply unit 24, and the light irradiation unit 29, if the power button 61 is pressed briefly, an operation signal can be input to further operate one of the magnetic unit 21, the air supply unit 24, and the light irradiation unit 29 that is not in operation.

[0091] The adjustment buttons can input operation signals that can adjust the intensities of the magnetic unit 21, the air supply unit 24, and the light irradiation unit 29 individually or collectively.

[0092] For example, the adjustment button can adjust the strength of the magnetic field of the magnetic unit 21 by adjusting the strength of the power applied to the magnetic unit 21, can adjust the rotation speed of the fan 27 of the air supply unit 24, and can adjust the amount of illumination of the light irradiation unit 29.

[0093] The control unit 50 can operate the magnetic unit 21, the air supply unit 24, and the light irradiation unit 29 each time an operation signal is input by the operation unit 60, and can also operate them simultaneously.

[0094] Here, the method of inputting the operation signals of the magnetic unit 21, the air supply unit 24, and the light irradiation unit 29 using the power button 61 and the main function button 62 can be set in various ways, and is not limited thereto.

[0095] In addition, the non-sealed virus and bacteria blocking device of the present invention may further include a display unit 70 for checking whether the power supply unit 40 is on / off, whether the magnetic unit 21, the air supply unit 24 and the light irradiation unit 29 are operating, the remaining battery level, the intensity state, etc. In this case, the display unit 70 may be configured as a lamp or a display unit, but is not limited thereto.

[0096] In addition, the non-sealed virus and bacteria blocking device of the present invention may further include a confirmation unit that allows a user to confirm the input of an activation signal by the operation unit 60. In this case, the confirmation unit may be, but is not limited to, a vibration motor that generates vibrations or a speaker that outputs sound.

[0097] Meanwhile, the non-sealed virus and bacteria blocking device of the present invention may further include a sensing sensor and a voice recognition unit.

[0098] The detection sensor can detect a third person within a preset distance from the user wearing the main body 10. In this case, the detection sensor may be an infrared sensor, but is not limited thereto.

[0099] Also, the control unit 50 can control the operation of the cutoff unit depending on whether or not a third party has been detected.

[0100] That is, the control unit 50 can control the cutoff unit 20 with a preset operation signal according to the set distance from the third person.

[0101] For example, when a user wearing a non-sealed virus and bacteria blocking device converses with or eats with a third party, if the control unit 50 detects the third party within 50 cm of the distance, it can input an activation signal to activate all of the magnetic unit 21, air supply unit 24, and light irradiation unit 29, and if the third party is outside 50 cm, it can input an activation signal to activate only the magnetic unit 21.

[0102] In another example, the set distance may be set to a first distance or a second distance longer than the first distance. In this case, the control unit 50 may operate all of the magnetic unit 21, the air supply unit 24, and the light irradiation unit 29 when the distance between the user and the third person is within the first distance, operate the magnetic unit 21 and the air supply unit 24 when the distance is between the first distance and the second distance, and operate only the magnetic unit 21 when the distance is longer than the second distance. This is an example, and is not limited thereto, and the control of the blocking unit 20 may vary depending on the setting.

[0103] The voice recognition unit can recognize the user's voice.

[0104] At this time, when a preset voice is recognized by the voice recognition unit, the control unit 50 can control the operation of the cutoff unit 20. A preset operation signal can be set to the preset voice.

[0105] That is, when the user speaks a preset voice, the voice recognition unit recognizes the preset voice, and the cutoff unit 20 is operated with a preset operation signal according to the preset voice.

[0106] For example, the preset sound can be set to "activate magnetic unit", and when the sound "activate magnetic unit" is recognized, the control unit 50 can activate the magnetic unit 21. This is merely an example, and the present invention is not limited to this, and the cutoff unit 20 can be controlled in various ways by various preset sounds.

[0107] As described above, in the non-sealed virus and bacteria blocking device of the present invention, the magnetic unit 21, the air supply unit 24, and the light irradiation unit 29 can receive operation signals in various ways, but are not limited thereto.

[0108] Those skilled in the art will understand that the present invention may be embodied in other specific forms without changing the technical concept or essential features of the present invention. Therefore, it should be understood that the above-described embodiments are illustrative in all respects and are not limiting. The scope of the present invention is defined by the claims below rather than the above detailed description, and all modifications and variations derived from the meaning and scope of the claims and their equivalent concepts should be interpreted as being included in the scope of the present invention. In addition, the operating order of the components described in the above process does not necessarily have to be performed in chronological order, and it goes without saying that such a process can fall within the scope of the present invention even if the order of performing each component and step is changed as long as the gist of the present invention is met.
