TECHNICAE FIELD

[0001] The present disclosure relates to the field of filtration and disinfection of air and surfaces. More particularly, the present disclosure relates to a system for purification and disinfection of indoor air and surfaces.

BACKGROUND

[0002] Background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.

[0003] Along with the day-to-day changing conditions of the world, the lifestyle of people is also changing rapidly. Increased pressure over natural resources due to rapid rise in population, insensitivity towards environment and ecology, ruthless cutting of trees, over use of plastic and generation of plastic and generation of indecomposable waste, global warming, etc., has led to accelerated deterioration in condition of surroundings and the whole world. Moreover, pollution is also increasing continuously due to human activities, such as, haphazard industrialization, discharging of untreated water from industries, increased use of insecticides and pesticides, increased use of personal vehicles that result in increased consumption of petroleum products, and thereby, increased production of smog, carbon-di-oxide, carbon monoxide, Sulphur-di-oxide, and other such gases contributing in increase of global warming and pollution.

[0004] Due to all such activities, level of pollution is crossing a new milestone every day, which can prove to be very harmful for all the living organisms including human beings, animals, as well as plants. Many species of plants and animals have become extinct and more are at the verge of extinction due to such changes in global conditions. Pollution is directly affecting people of every age, and air pollution is one of the major factors that is causing various health related issues in people. Air pollution directly affects the respiratory system of normal people as well as people already having respiratory disorders or breathing problems. Therefore, such an increase in levels of air pollution leads to health deterioration of normal people resulting in suffocation, Asthma, and other breathing, lungs-related, and heart-related problems. Moreover, it may prove to be more detrimental and life risking for the people already having such respiratory disorders and problems. [0005] As per a report of World Health Organization (WHO) on Air pollution, 9 out of every 10 people breathe air having high levels of pollutants, and around 4.2 million deaths occur every year due to air pollution.

[0006] Moreover, now-a-days various air-borne diseases have also become a cause of concern. For example, according to latest claims Coronavirus can sustain in air for an effective time period, which may result in spread of the virus in a wider area, thereby, affecting more people. Due to the air-borne nature of COVID- 19 causing Coronavirus it has become challenging to control and stop it’s spread and transmission from person-to-person.

[0007] Various air ventilation systems and Heating, Ventilation and Air-Conditioning (HVAC) systems are available in the market, which allow flow of air from an outside location (environment) to indoors, and recirculate indoor air too. However, such ventilation or HVAC systems do not focus much on the quality of air being brought from the outside location into the indoors, or the stale quality of recirculated indoor air. Increased pollution level in the environment has polluted the air present in the outside environment to an extent that it has become very dangerous and the quality of air present indoors can be even worse, and therefore use of such ventilation or HVAC systems for supplying untreated air inside buildings can be very dangerous for the health of people inside such indoor environment. Moreover, such systems may result in transmission of air-borne diseases along with the recirculation of indoor air that may prove to be detrimental for people within the premises.

[0008] Various equipment for cleaning of surfaces are present in the market, such as disinfectant solutions, scrubbing elements, wipers, etc. However, such equipment fail to clean and disinfect a surface efficiently, and also lead to spread of infections and diseases when a person comes in contact with the infected surface during the process of cleaning.

[0009] There is, therefore, a need in the art to develop a system to resolve the above- mentioned and related problems, and to provide effective disinfection and purification of indoor air as well as surfaces.

[00079] Thus, it will be appreciated by those of ordinary skill in the art that the diagrams, schematics, illustrations, and the like represent conceptual views or processes illustrating systems and methods embodying this invention. The functions of the various elements shown in the figures may be provided through the use of dedicated hardware as well as hardware capable of executing associated software. While embodiments of the present invention have been illustrated and described, it will be clear that the invention is not limited to these embodiments only. Numerous modifications, changes, variations, substitutions, and equivalents will be apparent to those skilled in the art, without departing from the spirit and scope of the invention, as described in the claim.

[00080] In the foregoing description, numerous details are set forth. It will be apparent, however, to one of ordinary skill in the art having the benefit of this disclosure, that the present invention may be practiced without these specific details. In some instances, well-known structures and devices are shown in block diagram form, rather than in detail, to avoid obscuring the present invention.

[00081] As used herein, and unless the context dictates otherwise, the term "coupled to" is intended to include both direct coupling (in which two elements that are coupled to each other contact each other) and indirect coupling (in which at least one additional element is located between the two elements). Therefore, the terms "coupled to" and "coupled with" are used synonymously. Within the context of this document terms "coupled to" and "coupled with" are also used euphemistically to mean “communicatively coupled with” over a network, where two or more devices are able to exchange data with each other over the network, possibly via one or more intermediary device.

[00082] It should be apparent to those skilled in the art that many more modifications besides those already described are possible without departing from the inventive concepts herein. The inventive subject matter, therefore, is not to be restricted except in the spirit of the appended claims. Moreover, in interpreting both the specification and the claims, all terms should be interpreted in the broadest possible manner consistent with the context. In particular, the terms “comprises” and “comprising” should be interpreted as referring to elements, components, or steps in a non-exclusive manner, indicating that the referenced elements, components, or steps may be present, or utilized, or combined with other elements, components, or steps that are not expressly referenced. Where the specification claims refers to at least one of something selected from the group consisting of A, B, C . . ..N, the text should be interpreted as requiring only one element from the group, not A plus N, or B plus N, etc.

[00083] While the foregoing describes various embodiments of the invention, other and further embodiments of the invention may be devised without departing from the basic scope thereof. The scope of the invention is determined by the claims that follow. The invention is not limited to the described embodiments, versions or examples, which are included to enable a person having ordinary skill in the art to make and use the invention when combined with information and knowledge available to the person having ordinary skill in the art.
