BACKGROUND OF THE INVENTION

Field of the Invention:

[0022] In aspects, the invention disclosed herein is directed to an exhaled air purification unit/device and/or system providing the ability to capture/collect, isolate, transport, and/or destroy airborne pathogens and contaminants faster than currently available HVAC systems, HVAC purification systems, and/or HVAC air handling systems, permit. The invention disclosed herein is directed, in aspects, to an exhaled air purification unit and/or system that is capable of capturing/collecting, isolating and cleaning the exhaled air of a plurality of individuals. In most but not all cases these individuals are seated. By way of example only, airborne pathogens can float for over 15 minutes within a building traveling great distances before they are captured by the HVAC return. This especially true for auditoriums, theaters, and schools. It is estimated that around 70% of the day spent at school is spent sitting at a desk or table. As with auditoriums, theaters, and school classrooms, many times the closest HVAC air return is far across the room from where an individual is seated. Thus, exhaled air of multiple individuals must travel in the air across multiple rows of seats, desks, and/or tables before it is captured within the HVAC air return. This is also true when considering an air purifier. An air purifier pulls air from a room through the air purifier thus cleaning the air. However, an air purifier, like that of the HVAC system cleans the room air “after” exhaled air is very dispersed throughout the air of the indoor venue. Thus, any contagious pathogens will have floated through the air of the indoor venue for some time before being captured and cleaned.

[0023] Currently, additional airflow and/or upgraded HEPA filters are being added to many schools and universities air handling systems. While this will help somewhat in reducing pathogen spread, it will not adequately or sufficiently satisfy the need. Simply upgrading the HVAC system will not significantly reduce the potential of pathogen airborne contagious spread within a building or vehicle environment. There is a pressing need to capture and isolate exhaled air of an individual or individuals much closer to the face of an individual or individuals. By doing this, a cone of exhaled air from an individual is significantly reduced in cubic area and diameter and it is possible to capture and/or isolate part of most of it.

Description of the Related Art:

[0024] Aerosol spray which transports viruses, including coronavirus (“COVID”), occurs from a human exhaled breath, talking, shouting, coughing, and sneezing. Under normal circumstances it is known that exhaled air forms a cone shape as it comes from the mouth and nose of an individual. Generally, at its origination at the nose and mouth it is approximately 55mm in diameter. From there it usually (but not always) expands outward at 22 degrees to 33 degrees and has a center trajectory of 10 degrees downward. The louder the noise the human makes with his or her voice, lungs, throat, or mouth generally the farther the viral or bacterial aerosol is moved in the air. Recent studies show that an aerosol comprising viral float can remain airborne for up to 15 minutes in a closed confined environment. Research studies have showed that singing, yelling, coughing, and sneezing can spread COVID aerosol up to 3+ meters. The velocity of exhaled air can range between 0.8 meters per second to 50 meters per second depending upon an easy breath of exhaled air to that of a sneeze, with a cough being somewhat less than a sneeze. By way of example only, COVID 19, COVID variants, coronavirus, measles, mumps, SARS, smallpox, common colds, influenza, and tuberculosis can be spread by way of being airborne. Closed confined multi-seated indoor environments are extremely vulnerable to coronaviral spread. There is a need for capturing, isolating, and cleaning the exhaled air of individuals far more quickly than what is done today.

SUMMARY OF THE INVENTION

[0025] In embodiments of the present invention, an exhaled air purification system may comprise one or a plurality of exhaled air collectors networked to one or more remote air purification chambers. An exhaled air purification unit may comprise an exhaled air collector and an exhaled air purification chamber. The exhaled air purification unit can be mobile and can be moved, by way of example only, from a tabletop to a different tabletop, from desk to a different desk, from back of a chair or seat to a different back of a seat or chair, or any combination thereof. The exhaled air purification unit can be fixed and thus not moved. The exhaled air collector can be positioned on a desktop or tabletop, attached to a seat back, integrated within a seat back, or distance separated and behind a seat back. A seat back can be formed or shaped to be an exhaled air collector. An exhaled air collector in most, but not all cases, can comprise an open front.

[0026] The exhaled air collector captures, collects exhaled air from and individual whose face is generally within 2 inches to 6 feet of the front of the exhaled air collector or an exhaled air guide connected to an exhaled air collector. In some cases, it can be within 1 foot to 6 feet and in other cases it can be 3 feet to 6 feet, by way of example only. The way the exhaled air is collected and captured by the exhaled air collector is a combination of the velocity of the individual’s exhaled air being collected, plus the trajectory of the individual’s exhaled air combined with the air intake suction force of the exhaled air purification unit, or, said another way, the air intake suction force of the air suction intake located, in aspects, within, connected to, or on a part of the exhaled air collector.

[0027] An exhaled air collector can comprise an internal back recessed air blocking surface. An exhaled air collector can comprise an optional exhaled air catch basin. The exhaled air collector is designed to capture an amount of the exhaled air of an individual sitting in front of the exhaled air collector and to move or permit the captured exhaled air to move into an air purification chamber for cleaning, filtering, purifying or any combination thereof. In embodiments, the exhaled air moves along with or is permitted to move along with air from the venue in which the individual is sitting or standing.

[0028] In embodiments, the exhaled air collector can comprise an internal recessed air blocking surface. However, in certain embodiments the exhaled air collector can be devoid of a recessed exhaled air blocking surface and can open in its back to an exhaled air purification chamber that can be of the entire size of the back of the exhaled air collector. The exhaled air purification chamber in this case can comprise air suction intakes on the side that are common with the exhaled air collector and air exhaust outlets on the side that are common with the venue environment. In certain other embodiments the air suction intake side of the exhaled air purification chamber can fill a portion, or all, of one or more of the top, the side, the bottom, and/or the back of the exhaled air collector. An exhaled air suction intake can be an opening within a wall, floor, top, or bottom of the exhaled air collector that allows air to flow towards an air suction mechanism that provides an air suction force to such opening within the exhaled air collector. Such an air suction mechanism can be, by way of example only, a fan. The way the exhaled air collector, the exhaled air purification chamber, and/or that of the exhaled air purification unit is designed largely depends upon the venue to which it is being utilized.

[0029] As used herein a desk and table can have the same meaning. As used herein a desk and tabletop can have the same meaning. As used herein a table and desktop can have the same meaning. As used herein a desk and table can be that of a chair, a seat, or a bench that comprises a desk like attachment. As used herein a desk and table can be that of chair, seat or bench that comprises a writing ledge attachment. As used herein a desk and table can be that of chair, seat or bench that comprises an attached or integrated horizontal work surface. While in most embodiments an individual is sitting or standing in front of an air purification unit resting on a desk or a table, the invention disclosure herein covers that of an individual standing in front of a standing desk or table that further supports a computer, by way of example only, a tablet, a laptop, or a desktop.

[0030] As used herein an airborne particulate can be that of, but is not limited to, a virus, bacteria, fungus, pathogen, or contaminant. As used herein a pathogen can include bacteria, fungi, protozoa, worms, viruses, and even infectious proteins called prions. As used herein, “seat,” “chair,” “bench,” and “sitting apparatus,” have the same meaning and can be used interchangeably. As used herein the word “clean” or variations thereof can have the same meaning as purify. Clean air can mean the same as cleaned air. Cleaned air can be that of filtered air. Cleaned air can be that of purified air. Cleaned air can be that of sterilized air. The words purify and/or clean can imply that of partially cleaned, partially purified, or fully cleaned and fully purified. As used herein an exhaled air purifier can mean the same thing as an exhaled air purification chamber. Such exhaled air cleaning/purification can occur by way of one or more of: filtration, chemical microbicidal purification, light microbicidal purification (such as, by way of example only, UVC light), mechanical microbicidal purification, thermal microbicidal purification, microbicidal agents, or microbicidal materials. It is understood and implied herein that when exhaled air is collected and cleaned or purified, air from the room and/or venue is also mixed with the collected exhaled air. Thus, when using the terms exhaled air collector, exhaled air purification chamber, or exhaled air purification unit, it is understood that the collector, chamber, and purification unit will always be handling and processing both exhaled air and some of the venue’s room air. As used herein an exhaled purification system means the same as an exhaled air purification system. As used herein, an air purification unit means the same as an air purification device. As used herein an air purification device means the same as an air treatment device or air treating device, and an air treatment device or air treating device can mean the same as an air purification unit.

[0031] An electronic display screen, video display screen, or display screen can all have the same meaning. As used herein someone that is sitting or standing “in front” of an exhaled air purification unit is that of someone sitting or standing at a table as depicted in the figures included with this invention disclosure. As used herein someone sitting behind a chair, seat, or bench is sitting in the chair, seat, or bench behind that of the chair, seat, or bench that is in front thereof. As used herein the back of a chair, seat, bench is the backrest and/or headrest of the chair, seat, or bench.

[0032] As used herein the abbreviation CADR is basically a reflection of the air flow (CFM - cubic feet per minute) times the efficiency of the air filter. So, if an air filter has 200 cfm and 100% efficiency the CADR would be 200. If the air filter has 200 cfm and 75% efficiency the C ADR would be 150. As used herein CFM means cubic feet per minute of air flow.

[0085] The present invention has been described with reference to particular embodiments having various features. It will be apparent to those skilled in the art that various modifications and variations can be made in the practice of the present invention without departing from the scope or spirit of the invention. One skilled in the art will recognize that these features may be used singularly or in any combination based on the requirements and specifications of a given application or design. Embodiments comprising various features may also consist of or consist essentially of those various features. Other embodiments of the invention will be apparent to those skilled in the art from consideration of the specification and practice of the invention. The description of the invention provided is merely exemplary in nature and, thus, variations that do not depart from the essence of the invention are intended to be within the scope of the invention. [0086] All references cited in this specification are hereby incorporated by reference in their entireties.

[0087] The present invention relates to capturing and cleaning, purifying, sanitizing, or otherwise conditioning or treating exhaled air from a human, then returning that air to the same environment, or in cases not returning that air to the same environment.

[0088] In aspects, the present invention can be used in a multi-person environment or venue such as a school, classroom, teaching facility, learning environment, auditorium, music studio, or anyplace else where more than one person can be found in close enough proximity to infect, communicate, transmit, or otherwise spread with one another any airborne illness, virus, sickness, microbe, pathogen, or any other condition, element, or particulate that can be communicable from one human to another. As explained herein, the invention includes, in aspects, an exhaled air collector to collect exhaled air from a human, which in cases may also include one or more of the following: exhaled air guide, an air suction intake, an air suction conduit, or an air purification chamber. An air purification chamber can be one or more of: partially or fully within an exhaled air collector, connected to an exhaled air collector, attached to an exhaled air collector, supported by a desktop or tabletop, attached under a desktop or tabletop, attached to a desktop or tabletop, within a seat back, within a seat, under a seat, distance separate but directly behind a seat or seatback, remote to a desktop or tabletop, and/or remote to a seat back or seat. In embodiments of the present invention, an exhaled air purification system may comprise a plurality of exhaled air collectors networked to one or more remote air purification chambers. An exhaled air purification unit may comprise an exhaled air collector and an exhaled air purification chamber. The exhaled air purification unit can be mobile and can be moved, by way of example only, from a tabletop to a different tabletop, from desk to a different desk, from a back of a chair or seat to a different back of a seat or chair, or any combination thereof. The exhaled air purification unit can be fixed in position or location. The exhaled air collector can be positioned on a desktop or tabletop, attached to a seat back, integrated within a seat back, or distance separated and behind a seat back. A seat back can be formed or shaped to be an exhaled air collector. In a preferred embodiment, an exhaled air collector can comprise a partially or completely open front. An open front exhaled air collector can permit an individual to position his or her hands within the open front exhaled air collector and/or to place all or a portion of an item within the open front, such as computer, phone, book, writing instrument, paper, notebook, document, food, keyboard, instrument, microphone, or any other item within the open front and therefore, in aspects, partially or completely within the exhaled air collector or the cavity of the open front exhaled air collector. Thus, the open front air collector can allow for an individual to, by way of example only, hold and/or touch all or a portion of, within the open front exhaled air collector, food, paper, reading material, books, magazines, writing material, computer, and/or electronic display. An exhaled air collector can be used when standing, sitting, or laying. In embodiments where the exhaled air collector partially or completely surrounds a microphone, the front of the air collector can have an open front (see, e.g., FIG. 49). The exhaled air collector can comprise an open front, wherein the open front of the exhaled air collector allows for an electronic display to be viewed and touched by an individual or individuals whose air the exhaled air collector is collecting.

[0089] In embodiments, the exhaled air collector can collect the exhaled air of one or multiple individuals who are in front or substantially in front of the exhaled air collector. When multiple individuals are in front of an open front of an exhaled air collector, the exhaled air collector can comprise a left-to-right dimension (length, width, and/or height) capable of accommodating multiple individuals. In embodiments, an exhaled air collector capable of accommodating more than one individual can be divided into multiple sections, each in front of one individual or groups of individuals, in aspects. In embodiments, where more than one individual is located or positioned next to one another, multiple exhaled air collectors can be used, and they may be adjacent and/or connected to one another. An exhaled air collector for multiple individuals can have one or multiple air suction intakes; in aspects, each individual has his or her own air suction intake and in cases air suction intakes are shared between more than one individual. These one or multiple air suction intakes can connect to one or more common or shared air suction conduit(s) that connect to one or more exhaled air purification chambers, or each air suction intake can have its own air suction conduit that connects to one or more exhaled air purification chambers. [0090] An exhaled air collector can comprise an internal back recessed air blocking surface. An exhaled air collector can comprise an optional exhaled air catch basin. The exhaled air collector can be designed to capture an amount of the exhaled air of an individual sitting in front of the exhaled air collector and to move or permit the captured exhaled air to move into an air purification chamber for cleaning, filtering, purifying, or any combination thereof. In embodiments, the exhaled air moves along with or is permitted to move along with air from the venue in which the individual is sitting or standing.

[0091] In embodiments, the exhaled air collector can comprise an internal recessed air blocking surface. In embodiments, the exhaled air collector can be devoid of a recessed exhaled air blocking surface. In embodiments the exhaled air collector can have an exhaled air guide to deflect a portion of an individual’s exhaled air into the exhaled air collector. The exhaled air guide can be adjustable. The exhaled air guide can be fixed. In certain embodiments the exhaled air collector can comprise one or more fans to move exhaled air.

[0168] In aspects, an exhaled air purification unit can comprise a sensor that can sense the presence or absence of an individual that is within 3 feet of the front of the exhaled air purification unit, by way of example. In aspects, an exhaled air purification unit can comprise a sensor that can sense the presence or absence of an individual that is within 3 feet of the front of the exhaled air collector, by way of example. The sensor can be one or more of an infrared (“IR”) sensor, motion detector, photosensor, or vision system sensor. The sensor can turn the exhaled air purification unit on when an individual is sitting or standing within a set distance of the air purification unit and the sensor can turn the exhaled air purification unit off when the individual is no longer present. By way of example only, the sensor can determine, in aspects, if someone is sitting or standing at the desk or table supporting the exhaled air purification unit. An IR sensor can sense if an individual sitting or standing at the desk or table supporting an exhaled air purification unit has a body temperature above a certain threshold. By way of example only, if the IR sensor senses a temperature of, by way of example only, 98° F or above, it can cause a speed of a fan or fans within or attached to one or more of the exhaled air purification unit, exhaled air collector, air suction intake, air suction conduit, and/or exhaled air purification chamber, to increase in velocity or cubic feet per minute. In addition, the IR sensor can cause the fan or fans of the exhaled air purification unit(s), air collector(s), and/or conduit(s) in or attached to the seats (or on a table or desk) to the right and/or left of the seat, table, desk, or work area directly in front to go to a higher CFM (cubic feet per minute of air flow). Thus, in certain embodiments, a fan or fans located within or attached to the exhaled air purification unit can operate at two or more different CFMs. Accordingly, in embodiments, a fan or fans located within or attached to the exhaled air collector can operate at two or more different CFMs. In embodiments a fan or fans located within or attached to the exhaled air purification chamber can operate at two or more different CFMs. In embodiments, a fan or fans located within or attached to a section or part of an exhaled air purification system or unit can operate at two or more different CFMs.

[0169] A networked exhaled air purification system that comprises a plurality of networked exhaled air collectors and/or exhaled air purification units that connect to one or more remote exhaled air purification chambers can comprise a sensor capable of determining if an individual is within 3 feet of the front of the exhaled air collector or exhaled air purification unit. A sensor, by way of example only, can be an IR sensor, which can determine, in aspects, a) if someone is sitting or standing in front of the exhaled air purification unit, and/or b) if an individual sitting or standing in front of the exhaled air purification unit has a body temperature above a certain threshold. By way of example only, if the IR sensor senses a threshold of a temperature of 98° F or above it can cause speed of a fan within or attached to the exhaled air purification unit, and optionally fans associated with exhaled air purification units to the right and/or left and or in front or behind the sensed air purification unit to go to a higher CFM. Thus, in certain embodiments, the fan or fans located within or attached to the exhaled air purification unit can operate at two or more different CFMs.

[0170] In certain embodiments of the invention, the exhaled air purification unit can comprise a carbon dioxide (“CO2”) sensor. The exhaled air collector can comprise a CO2 sensor. The exhaled air purification chamber can comprise a CO2 sensor. The exhaled air purification system can comprise a CO2 sensor. A higher CO2 level can indicate a lack of good or sufficient air circulation within an indoor venue. Depending upon the level of CO2 measured, the CO2 sensor can cause a fan’s CFM to increase or decrease in CFM. The exhaled air purification unit, air purification chamber, and/or air purification system can comprise an ozone sensor and cause an alarm, alert, or notification if ozone is present and/or if the level of ozone exceeds a preset threshold.

[0171] In embodiments, an air purification unit can include an acoustic sensor located, for example, within, on, or attached to, for example, an exhaled air collector. In aspects, the acoustic sensor can detect a sound, such as a cough, sneeze, voice, etc., and the air purification unit can in turn activate or change a speed of a fan in, on, or attached to the air purification unit. For example, if the sensor detects a sound, it can cause the air purification unit to increase a fan speed for, in aspects, a predetermined set amount of time.
