BACKGROUND

Field of Invention

1. Embodiments of the present invention generally relate to environmental protection equipment and particularly to a multipurpose air purifying device that is adapted to provide a purified fragrant air to an ambient environment and simultaneously sanitizing the ambient environment, a user hand, a user body and surfaces.

Description of Related Art

2. Air pollution is one of a major problem of urban areas. It is essentially caused due to an introduction of particulates, biological molecules, or other harmful materials into an Earth's atmosphere, leading to detrimental effects on a human health. In fact, an indoor air pollution and an urban air quality are listed as two of the world’s worst toxic pollution problems. The air pollution is a mixture of air pollutants such as, particles, gases, and so forth that can reach harmful concentrations both outside and indoors. The air pollutants can be of a natural origin or a man-made. The air pollutants are classified in two categories; primary pollutants and secondary pollutants. The primary pollutants are usually produced from a process, for example, an ash from a volcanic eruption, a Carbon Monoxide (CO) gas from a motor vehicle exhaust, or a Sulfur Dioxide (SO2) gas released from factories and so forth. The secondary pollutants form in the air when the primary pollutants react or interact. Some pollutants may be both the primary pollutants and the secondary pollutants: they are both emitted directly and formed from the other primary pollutants. The air pollution is a silent and an invisible problem. While air purifiers make an indoor air cleaner and safer to breathe in, air fresheners are only using a chemical formula to suppress the existing pollutants. Therefore, where the air cleaned by the air purifiers is healthier, the air freshened by the air fresheners is simply a chemically altered air. For example; the air inside a room or a public washroom, where the air fresheners are used, a user feels humid due to overcrowding of elements in an ambient environment. Further, in a present scenario, a most effective prevention against any outbreak, an epidemic or a pandemic is a sanitization of hands and other areas that are prone to bacteria or viruses apart from the purified air that we breathe in. As a preventive measure, it is suggested medically that the hands of the user should be sanitized after every half an hour to maintain a proper hygiene and minimize a risk of getting infected by the bacteria, microbes and the viruses. Conventionally, hand sanitizershave been introduced, which enables the user to press a button or use an automatic hand sanitizer machine for spraying the sanitizer. However, the user needs to take care of minute things due to the increasing pollution that further leads to generation of the bacteria and the virus, resulting in a low immunity level among the users. Moreover, such type of hand sanitizers may be effective in sanitizing the hands but can’t address the issues that get generated via the air pollution. Further, no prior art teaches, or suggests the usage of an air purifier combined with a hand sanitizer for a multipurpose usage.

5. There is thus a need for an advanced and more effective multipurpose air purifying device that can administer the drawbacks faced by the conventional purifying devices regarding air, surface, hand and body purifiers / sanitizers/ cleaners / fresheners / disinfectants/ sterilizers and more.

FIG. 2 illustrates components of the control unit 144, according to an embodiment of the present invention. The control unit 144 may include a data receiving module 200, a comparison module 202, and a pump control module 204. The data receiving module 200 may be configured to receive the sensed distance from the second distance sensor 142. In an embodiment of the present invention, the data receiving module 200 may be configured to transmit the received distance to the comparison module 202. The comparison module 202 may be configured to compare the distance with a second pre-defined distance stored in the secondary memory. In an embodiment of the present invention, if the comparison module 202 determines that the distance between the hands of the user and the moisturizer dispenser 140 (as shown in the FIG. 1B) is less than or equal to the second pre-defined distance, then the comparison module 202 may be configured to generate a pump activation signal.

In another embodiment of the present invention, if the distance between the hands of the user and the moisturizer dispenser 140 is greater than the second pre-defined distance, then the comparison module 202 may enable the data receiving module 200 to continue to receive the sensed distance from the second distance sensor 142. FIG. 3 depicts a flowchart of a method 300 of providing the purified fragrant air by using the air purifying device 100, according to embodiments of the present invention. At step 302, the air purifying device 100 may pull the polluted air from the ambient environment into the first cartridge 106 through the air inlet 108 by using the fan 112, when the power of the air purifying device 100 is turned on. At step 304, the air purifying device 100 may remove the contaminants from the polluted air by using the first layer of filter 118 and the second layer of filter 120. At step 306, the air purifying device 100 may enable the purified air to pass through the second cartridge 126 having the fragrance substance to entrain the fragrance into the purified air. At step 308, the air purifying device 100 may expel the purified air that may be entrained with the fragrance from the first cartridge 106 to the ambient environment through the air outlet 110 by using the fan 112. At step 310, the air purifying device 100 may compare a duration of sanitizer dispensed time with the pre-defined time intervalor based on a requiremenent of the user as and when required. At step 312, the air purifying device 100 may dispense the pre defined amount of the sanitization solution stored in the sanitizer container 130, when the duration of sanitizer dispensed time is greater than or equal to the pre-defined time interval. Otherwise, the method 300 may return to the step 302. Further, the method 300 may conclude when the power of the air purifying device 100 is turned off. FIG. 4 depicts a flowchart of a method 400 for automatically dispensing the moisturizing solution by the air purifying device 100, according to embodiments of the present invention. At step 402, the air purifying device 100 may receive the distance between the hands of the user and the moisturizer dispenser 140 from the second distance sensor 142. At step 404, the air purifying device 100 may compare the sensed distance between the hands of the user and the moisturizer dispenser 140 with the second pre defined distance. At step 406, if the air purifying device 100 determines that the sensed distance is less than or equal to the second pre-defined distance, then the method 400 may proceed to a step 408, on the other hand if the air purifying device 100 determines that the sensed distance is greater the second pre-defined distance, then the method 400 may return to the step 402. At the step 408, the air purifying device 100 may actuate the moisturizer pump of the moisturizer dispenser 140 through the moisturizer motor to dispense the pre-defined quantity of the moisturizing solution onto the hands of the user.
