Description

Technical Field

[0001] The present invention relates to a non-enclosed virus and bacteria blocking device that does not cover the mouth and nose. More specifically, it relates to a non-enclosed virus and bacteria blocking device that uses reverse magnetic force and wind force to push droplets or aerosols containing viruses or bacteria out of the mouth and nose to block their inflow when the mouth and nose are open, and sterilizes the viruses and bacteria through a visible light sterilization lamp. Background Art

[0002] Generally, a mask is an item that covers the mouth and nose to prevent the inhalation and dispersion of germs, dust, etc.

[0003] In particular, masks are worn to prevent infection from diseases such as colds, and 19 (COVID 19) is recommended to be worn compulsorily to prevent infection.

[0004] The U.S. Centers for Disease Control and Prevention (CDC), the World Health Organization (WHO) and other domestic and foreign epidemic prevention agencies, relevant organizations and experts believe that the main transmission routes of the new coronavirus include: first, airborne transmission caused by tiny respiratory droplets and aerosol particles (airborne infection), second, transmission of droplets through spraying (droplet infection), and third, contact transmission through contaminated hands touching the nose, mouth, and eyes (contact infection).

[0005] Specifically, airborne transmission refers to the virus floating in the air in the form of aerosols with particles smaller than 5μm or 0.001-1μm, and when others inhale the air, the virus is transmitted through the respiratory tract. In particular, aerosols are fine droplets that float in the air without sinking.

[0006] Droplet transmission refers to the form of infection in which viruses or bacteria are mixed in tiny droplets (droplets) such as saliva when an infected person coughs or sneezes, and enter the mouth and nose of others. Droplets mean "splashing water droplets". The size of droplets is 5-10μm. Generally, when you cough once, about 3,000 droplets (respiratory droplets) will be sprayed and fall within 2m in front, and the virus will also die. If the droplet size is less than 5μm, it is called a droplet nucleus.

[0007] Therefore, in order to avoid airborne and droplet transmission, you should fall more than 2 meters from the infected person and it is best to wear a mask.

[0008] However, since the mask seals the mouth and nose and must be removed when eating, there is a problem of exposure to other people's droplets and aerosols.

[0009] In addition, there is another problem. Even if a mask is worn, it cannot be completely fitted or sealed. Facial movements will create a gap between the face and the mask, and other people's droplets and aerosols will enter through the gap when breathing.

[0010] In addition, it is also difficult for infants, people with brain lesions, developmental disabilities, and patients with respiratory disorders to wear masks.

DETAILED DESCRIPTION

[0040] The advantages and features of the present invention and the implementation methods will become clear by referring to the embodiments described in detail below in conjunction with the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below, but can be implemented in various different forms, and these embodiments are only provided to ensure that the disclosure of the present invention is complete, and in the technical field to which the present invention belongs, the present invention is to fully inform the category of the present invention to people with ordinary knowledge, and the present invention is defined only by the category of the claims. Throughout the specification, the same reference numerals represent the same components.

[0041] Hereinafter, the present invention will be described with reference to the accompanying drawings for illustrating a non-enclosed virus and bacteria blocking device according to an embodiment of the present invention.

[0042] refer to Figure 1 The non-sealed virus and bacteria blocking device according to the present invention includes a main body 10 and a blocking part 20.

[0043] First, the body 10 is formed to be detachably attached to the user's body.

[0044] For example, the body 10 may be formed in a "C" shape with one side being open so as to be worn around the neck of the user.

[0045] At this time, the body 10 can be embedded in the neck, with both ends located at the clavicle of the user, or can be fixed around the neck or placed on the shoulder. In addition, a length adjustment portion can be provided, which can adjust the length of both ends, so that the body 10 can be adjusted according to the user's body structure or size. The area where it is placed on the neck or shoulder.

[0046] In addition, the middle portion of the body 10 may be elastic so that the two ends can return to their original state after being opened.

[0047] The body 10 of the non-enclosed virus and bacteria blocking device according to the present invention may be formed into a belt shape with one side open and spanning the neck or shoulder, and may be provided with blocking parts 20 at both ends.

[0048] For example, the body 10 may be formed as a "C"-shaped neckband that can be worn on the neck or shoulders. As another example, the body 10 may be formed in an "O" shape and placed on the head, or may be formed in a clamp or ring shape and fixed to the user's clothes, and is not limited thereto and may be formed in various shapes.

[0049] Inside the body 10, a power supply unit 40 may be provided, which provides power for driving the blocking unit 20 described later. At this time, the power supply unit 40 may be provided inside the blocking unit 20 described later, and may be made of a rechargeable battery. Also, outside the body 10, a charging port 11 electrically connected to the power supply unit 40 may be formed so that the power supply unit 40 can be charged by an external power source.

[0050] The charging port 11 may be formed of a micro 5-pin, a lightning 8-pin, or a USB C type, but is not limited thereto.

[0051] The barrier 20 is provided in the body 10 to prevent droplets or aerosols from entering the user's respirator. That is, the barrier 20 can push droplets or aerosols away from the user's respirator or sterilize them.

[0052] In addition, the blocking parts 20 are respectively provided at both ends of the body 10 formed in a “C” shape, and may be rotatably provided.

[0053] That is, since each user has different body sizes and structures, when the body 10 is worn on the neck or shoulders, the barrier portion 20 can be adjusted toward the user's respirator to discharge or disinfect droplets or aerosols around the user's respirator.

[0054] At this time, the barrier part 20 may be provided with a magnetic part 21 , an air supply part 24 , and a light irradiation part 29 on the main body 20 a .

[0055] At this time, the non-sealed virus and bacteria blocking device of the present invention may further include an angle adjustment part 30 .

[0056] The angle adjustment part 30 connects the body 10 and the blocking part 20, and can be rotated or bent in the front, back, left, and right directions to adjust the angle so that one side of the blocking part 20 faces the user's respirator. As described later, the magnetic part 21 and the air supply part 24 of the blocking part 20 can be rotated or bent by the angle adjustment part 30, thereby adjusting the angle of the magnetic field direction and the air supply direction.

[0057] For example, in the angle adjustment part 30, the body 10 and the blocking part 20 may be connected by a ball joint.

[0058] Reference Figures 2 to 3 , a protruding ball 31 is formed on the body 10, and the ball 31 is engaged with the other side of the blocking part 20 and can form an engagement groove 32 for forced rotation. That is, the blocking part 20 can move freely to change the direction and angle of one side of the blocking part 20, and can be combined to be forced to rotate, and the adjusted direction and angle can be firmly maintained to be free from external vibration or impact.

[0059] Furthermore, the angle adjustment portion 30 may be formed of a bending member made of a material such as metal, which can maintain a bent state when bent.

[0060] Also, the angle adjustment portion 30 may be formed of a joint portion that is connected to a plurality of joints and can be bent, and may be formed of a hinge structure or the like.

[0061] As described above, the angle adjustment portion 30 may be composed of various structures, in which the direction and angle of one side of the blocking portion 20 may be adjusted and may be fixed in the adjusted state.

[0062] At the same time, reference Figures 4 to 7 The blocking portion 20 may include one or more of a magnetic portion 21, an air supply portion 24, and a light irradiation portion 29 to prevent droplets or aerosols from entering the user's respirator.

[0063] First, the magnetic portion 21 can generate a magnetic field through the user's respirator to allow the generation of a reverse magnetic force in the droplets or aerosols.

[0064] At this time, the droplets or aerosols are composed of water droplets, which produce anti-magnetic force on the magnetic field.

[0065] At this time, diamagnetism refers to a phenomenon in which when a magnetic field acts on a substance, the magnetization direction is opposite to the magnetic field direction. At this time, representative diamagnets are gases and water other than metals and oxygen.

[0066] That is, the droplets or aerosols are composed of water droplets floating in the atmosphere, and when a magnetic field is applied from the magnetic portion 21 , the water droplets or aerosols are pushed in a direction opposite to the direction of the magnetic field.

[0067] In addition, the magnetic part 21 is rotatably disposed on the body 10, and the magnetic field direction can be adjusted. At this time, the magnetic part 21 is forcibly rotated on the body 10, the magnetic field direction is adjusted, and can be fixed in the adjusted state.

[0068] That is, when the magnetic part 21 adjusts the angle so that the magnetic field direction is toward the user's respirator, the magnetic field direction is set to the user's respirator, so the droplets or aerosols around the user's respirator are pushed away from the user's respirator by the reverse magnetic force, and the user can prevent viral and bacterial infection.

[0069] On the other hand, the magnetic part 21 may be formed to protrude in the magnetic field direction. That is, the magnetic part 21 is protrudingly formed at one side of the main body 20a of the blocking part 20, and may be rotatably provided.

[0070] At this time, the magnetic part 21 may be a plunger, an electromagnet composed of a coil 23 wound around the plunger, or a permanent magnet, but is not limited thereto.

[0071] In the magnetic part 21, the coil 23 is electrically connected to the power supply part 40. Therefore, depending on whether the power supply part 40 supplies power to the magnetic part 21, a magnetic field can be applied to the droplets or the aerosol.

[0072] Furthermore, the magnetic portion 21 may be formed with a cover 28 surrounding the plunger and the coil 23 .

[0073] Meanwhile, the blocking portion 20 may further include an air supply portion 24 .

[0074] The air supply 24 may supply air to the user's respirator to push droplets or aerosols out of the respirator.

[0075] At this time, the air supply part 24 may include a motor 26, which receives power from the power supply part 40 and rotates the shaft 25, and a fan 27, which is connected to the shaft 25. And, the fan 27 can discharge air to one side of the blocking part 20. At this time, the motor 26 is shown as being disposed inside the blocking part 20, but may also be disposed inside the body 10. In addition, an outlet 27a is formed on one side of the body 20a, and an inlet is formed on the other side of the body 20a, so that external air can flow into and be discharged to the inside of the blocking part 20 by the rotation of the fan 27.

[0076] In addition, the air supply part 24 may be rotatably provided on the body 10. Therefore, the air supply direction may be adjusted.

[0077] That is, the air supply direction can be adjusted to be directed toward the user's respirator according to the user's body structure or size.

[0078] At this time, in the attached drawings of the non-sealed virus and bacteria blocking device according to the present invention, the air supply part 24 and the magnetic part 21 are arranged together on the main body 20a of the blocking part 20, but not limited to this, the first blocking part having the magnetic part 21 or the air supply part 24 and the second blocking part having the air supply part 24 or the magnetic part 21 can also be respectively arranged on the main body 10.

[0079] At this time, when the first cut-off portion and the second cut-off portion are separated, they are rotatably arranged on the body 10, respectively, and the magnetic field direction and the air supply direction can be adjusted respectively. In addition, the first blocking portion is rotatably arranged on the body 10, and the second blocking portion is rotatably arranged on the first blocking portion.

[0080] In addition, since the magnetic part 21 and the air supply part 24 push the droplets or aerosols around the user's respirator to the outside of the user's respirator, 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.

[0081] In addition, the magnetic field of the magnetic part 21 can play a role in pushing aerosols with smaller sizes, and the air of the air supply part 24 can play a role in pushing droplets and aerosols with sizes larger than aerosols, but it is not limited thereto.

[0082] Meanwhile, the blocking portion 20 may further include a light irradiation portion 29 .

[0083] The light irradiation unit 29 can irradiate the user's respirator with visible light sterilization light to sterilize viruses and bacteria contained in droplets or aerosols.

[0084] At this time, visible light is light with a wavelength range that is perceived by the eyes, and is an electromagnetic wave with a wavelength of about 380 to 780 nm. Wavelengths greater than 780 nm are heat rays for infrared and radio, and wavelengths less than 380 nm are ultraviolet rays and x-rays.

[0085] At this time, the visible light with a wavelength of 405nm can react with oxygen to generate active oxygen that is harmless to the human body. In addition, the visible light with a wavelength of 405nm can kill 99.9% of harmful bacteria such as Escherichia coli, Staphylococcus aureus, Pneumococcus and antibiotic-resistant bacteria MASA.

[0086] The sterilization principle of visible light with a wavelength of 405nm is that it reacts with porphyrin in bacteria, etc. to produce active oxygen, which destroys bacteria and viruses.

[0087] That is, the visible light sterilization light is composed of visible light 405nm wavelength, which is not harmful to the human body like ultraviolet light, so it can be directly irradiated on the human skin. Therefore, the light irradiation unit 29 can sterilize the viruses and bacteria contained in the droplets or aerosols floating around the user's respiratory tract.

[0088] In addition, the light irradiation unit 29 may also be provided at the outlet 27 a or the inlet of the air supply unit 24 to sterilize the external air flowing in from the fan 27 of the air supply unit 24 or to sterilize the exhausted air.

[0089] In addition, the barrier 20 may be provided on one side of the barrier 20 provided with the light irradiation portion 29 , and the barrier 20 may be rotated or bent to adjust the sterilizing light irradiation direction of the light irradiation portion 29 .

[0090] At this time, the non-closed virus and bacteria blocking device of the present invention is shown in the accompanying drawings as having an air supply part 24, a magnetic part 21 and a light irradiation part 29 on the main body 20a of the blocking part 20, but is not limited to this. The first blocking part having the magnetic part 21 or the air supply part 24, the second blocking part having the air supply part 24 or the magnetic part 21, and the third blocking part having the light irradiation part 29 can be respectively arranged on the main body 10, the light irradiation part 29 can be arranged on the first blocking part or the second blocking part, and the present invention can also be arranged in the main body 10, so it is not limited to this.

[0091] Furthermore, since the light irradiation portion 29 can effectively disinfect the environment around the user, a plurality of light irradiation portions 29 may be provided along the length direction of the body 10 , and a plurality of light irradiation portions 29 may be provided in the barrier portion 20 .

[0092] In addition, when the magnetic part 21, the air supply part 24 and the light irradiation part 29 are integrally arranged, 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 not to interfere with each other.

[0093] Therefore, if Figure 7 As shown, the user can adjust the angle of the blocking part 20 while wearing the body 10 on the neck and shoulders. At this time, since the magnetic part 21 and the air supply part 24 can adjust the angles respectively, the magnetic field direction and the air supply direction can be adjusted differently.

[0094] At the same time, reference Figure 8 The non-enclosed virus and bacteria blocking device of the present invention may further include a control unit 50 and an operating unit 60 .

[0095] The control part 50 may control the operations of the magnetic part 21 , the air supply part 24 , and the light irradiation part 29 .

[0096] Furthermore, the control section 50 may control two or more of the magnetic section 21 , the air supply section 24 , and the light irradiation section 29 to operate simultaneously.

[0097] The operation part 60 is provided on the body 10 or the blocking part 20 , and can input operation signals of the magnetic part 21 , the air supply part 24 , and the light irradiation part 29 .

[0098] For example, the operation portion 60 may include a power button 61 , a main function button 62 , and an adjustment button.

[0099] The power button 61 can input an operation signal for turning on / off the power of the power supply unit 40. At this time, when the power button 61 is long pressed, an operation signal can be input to turn on / off the power.

[0100] In addition, the main function button 62 can input an operation signal for operating any one of the preset magnetic part 21, the air supply part 24, and the light irradiation part 29. At this time, if the main function button 62 is pressed once, the operation signal of the magnetic part 21 is input, if it is pressed for the second time or twice in succession, the operation signal of the air supply part 24 is input, and when it is pressed for the third time or three times in succession, the operation signal of the light irradiation part 29 can be input.

[0101] In addition, when one or more of the magnetic part 21, the air supply part 24 and the light irradiation part 29 are operated by the main function button 62, if the power button 61 is short pressed, an operation signal can be input to further operate any one of the non-operated magnetic part 21, the air supply part 24 and the light irradiation part 29.

[0102] The adjustment button can adjust or integrate the operation signals of the magnetic part 21 , the air supply part 24 and the light irradiation part 29 respectively.

[0103] For example, in the adjustment button, the magnetic part 21 can adjust the magnetic field strength by adjusting the allowable strength of the power supply, can adjust the rotation speed of the fan 27 of the air supply part 24, and can adjust the illumination of the light irradiation part 29.

[0104] Furthermore, each time an operation signal is input from the operation unit 60 , the control unit 50 may operate the magnetic unit 21 , the air supply unit 24 , and the light irradiation unit 29 separately according to a preset setting, or may operate them simultaneously.

[0105] At this time, the method of inputting the operation signals of the magnetic part 21 , the air supply part 24 , and the light irradiation part 29 using the power button 61 and the main function button 62 may be set in various ways, and therefore is not limited thereto.

[0106] In addition, the non-enclosed virus and bacteria blocking device of the present invention is further provided with a display unit 70, which can confirm the on / off state of the power supply unit 40, the working state of the magnetic unit 21, the air supply unit 24 and the light irradiation unit 29, the remaining amount of the battery, the strong and weak state, etc. In this case, the display unit 70 can be composed of a lamp or a display unit, but is not limited thereto.

[0107] In addition, the non-enclosed virus and bacteria blocking device of the present invention may further include a confirmation unit, and the user can confirm the operation signal input by the operation unit 60. At this time, the confirmation unit can be composed of a vibration motor that generates vibration, a speaker that outputs sound, etc., but is not limited thereto.

[0108] At the same time, the non-enclosed virus and bacteria blocking device of the present invention may also include a detection sensor and a voice recognition unit.

[0109] The detection sensor can detect a third party within a preset distance from the user wearing the body 10. At this time, the detection sensor can be an infrared sensor, etc., but is not limited thereto.

[0110] In addition, the control portion 50 may control the operation of the blocking portion according to whether the third party is detected.

[0111] That is, the control unit 50 may control the blocking unit 20 using a preset operation signal according to the set distance from the third party.

[0112] For example, when a user wearing a non-sealed virus and bacteria blocking device is talking or dining with a third party, if the distance of the third party is detected to be within 50 cm, the control unit 50 can input an operation signal for operating the magnetic part 21, the air supply part 24 and the light irradiation part 29, and if it is outside 50 cm, an operation signal for operating only the magnetic part 21 can be input.

[0113] As another example, the setting distance may be set to a first distance and a second distance greater than the first distance. At this time, when the distance between the user and the third party is within the first distance, the control unit 50 operates the magnetic unit 21, the air supply unit 24, and the light irradiation unit 29, when located within the first distance and the second distance, the magnetic unit 21 and the air supply unit 24 may be operated, and when the distance is greater than the second distance, only the magnetic unit 21 may be operated. Since this is an example, it is not limited thereto, and the control of the blocking unit 20 may vary according to the setting.

[0114] The voice recognition unit can recognize the user's voice.

[0115] At this time, when a predetermined setting voice is recognized from the voice recognition part, the control part 50 may control the operation of the barrier part 20. And, a preset operation signal may be set in the setting voice.

[0116] That is, when the user speaks a preset setting voice, the voice recognition part recognizes the setting voice and activates the barrier part 20 with a preset operation signal according to the setting voice.

[0117] For example, the setting voice may be "activate the magnetic part", etc., and when the voice of "activate the magnetic part" is recognized, the control part 50 may activate the magnetic part 21. Since this is an example, it is not limited thereto, and the blocking part 20 may be controlled in various ways by various setting voices.

[0118] As described above, in the non-enclosed virus and bacteria blocking device of the present invention, the magnetic part 21, the air supply part 24 and the light irradiation part 29 can input operation signals in various ways, and are not limited thereto.
