Accordingly, the components and the method steps have been represented, showing only specific details that are pertinent for an understanding of the present invention so as not to obscure the disclosure with details that will be readily apparent to those with ordinary skill in the art having the benefit of the description herein.

[0030] As required, detailed embodiments of the present invention are disclosed herein; however, it is to be understood that the disclosed embodiments are merely exemplary of the invention, which can be embodied in various forms. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a basis for the claims and as a representative basis for teaching one skilled in the art to variously employ the present invention in virtually any appropriately detailed structure. Further, the terms and phrases used herein are not intended to be limiting but rather to provide an understandable description of the invention.

[0031] Referring now to accompanying figures, particularly FIGS. 1-8, there is provided a hand held oxygen generating and air purifying device 100. The proposed device 100 is shaped like an e-cigarette. The device 100 includes a suction body 102 (represented as Section ‘B’ in FIG. 4) through which atmospheric air gets into the device 100 during respiration. As best seen in FIG. 7, the suction body 102 includes a check valve 104, a first filter 106, and a first casing 108 through which atmospheric air is forcibly introduced within a main body 110 of the device 100 during respiration process. The main body 110 of the device 100 includes a handle 110a debossed over the body 110. The handle 110a facilitates a user of the device 100 to comfortably grip the device 100. The filter 106 comprises a mesh filter or a filter made of nonwoven fabric or of like nature. The check valve or the back cover 104 is preferably made of but not limited rubber, and urethane having elasticity and restoring force. According to the embodiment, the check valve 104 is half-moon shaped and consists of an opening 104a at its centre. According to an embodiment, the opening 104a is preferably in a cross or plus shape. In operation, the opening 104a is opened and closed by the pressure of breathing or inhalation and due to the elasticity of the material of the check valve 104.

[0032] In an assembled configuration of the device 100 as seen in FIGS. 1-4 in conjunction with FIG. 7, the first filter 106 and the check valve 104 are engaged or mounted over the casing 108. Further, during assemblage, the casing 108 is operatively coupled to a distal end of the main body 110. The casing 108 is threaded (threads 108a) externally which rotatably engages to threading (not seen) present within the distal end of the main body 110. The casing 108 couples at the distal end of the main body 110 of the device 100 using a gasket creating a seal for the atmospheric air entering and passing through the device 100. The gasket is a loop of elastomer with a round cross-section that seated in a groove and compressed during assembly between the casing 108 and the main body 110. According to the embodiment, the gasket is an O-ring 125.

[0033] According to the embodiment, the hand held oxygen generating and air purifying device 100 further includes a solid oxygen filter 112 adapted for holding solid oxygen contained therein. The solid oxygen includes a compound preferably but not limited to calcium hydroxide, calcium oxide, potassium excess, calcium peroxide, magnesium peroxide, potassium peroxide, barium peroxide, and sodium peroxide. The solid oxygen compound obtained by redox reaction usually have small particle size of several micro (μm), which makes it difficult to breathe through the mouth and does not generate much oxygen upon reacting with atmospheric air. Thus, according to the best mode of operation, it is preferable to have the solid oxygen in a tablet of about 1˜5 mm particle size and this can be made using a granulator.

[0034] Further, according to the embodiment, the solid oxygen filter 112 is configured for holding the solid oxygen. The solid oxygen filter 112 is cylindrical in shape and is preferably made of nonwoven fabric or a mesh net.

[0035] Further, according to the embodiment, the oxygen generator 100 includes a solid oxygen filter support 114 having a dual cylindrical structure configured for housing and supporting the solid oxygen filter 112. The dual cylindrical structure 114a, 114b of the solid oxygen filter support 114 includes an inner cylinder 114a having a honeycomb perforated structure over its wall, and an outer cylinder 114b having a blocked or solid outer wall surface as seen in FIGS. 4 and 5. The solid oxygen filter support 114 further includes a pair of slots (such as a slot 114c) for engaging to a pair of hooks 116a of a solid oxygen filter support lid 116.

[0036] The solid oxygen filter support lid 116 (seen in FIG. 5) is mountable over the solid oxygen filter support 114 and engages thereto using the pair of hooks 116a of the lid 116. Although only one hook is visible, but it should be understood there are two for holding the lid 116 over the filter support 114. The solid oxygen filter support lid 116 further includes a set of openings or slits 116b. In an example, the slits 116b may be configured in a circular configuration for discharging the generated inhalable oxygen from the main body 110 to a second filter or micro filter 118 during the operation of the device 100. The micro filter 118 is tubular in shape and consists of micro fibres. The micro filter 118 removes contaminants present in the generated oxygen and prevent entry of moisture from outside environment while the device 100 is being used for oxygen generation and inhalation of generated oxygen.

[0037] According to the embodiment, as seen in FIGS. 4 and 8 (represented as Section A), the oxygen generator device 100 further includes a second casing 120 embodying the second filter/micro filter 118 and is operationally connected to a mouthpiece 122. During the assembly as shown in FIG. 1, the casing 120 is operatively coupled to a proximal end of the main body 110 of the device 100. The casing 120 is threaded (threads 120a) externally which rotatably engages to threading (not seen) present within the proximal end of the main body 110. The casing 120 couples at the proximal end of the main body 110 of the device 100 using a gasket creating a seal for the atmospheric air entering and passing through the device 100. The gasket is a loop of elastomer with a round cross-section that seated in a groove and compressed during assembly between the casing 120 and the main body 110. According to the embodiment, the gasket is an O-ring 130.

[0038] Further, the mouthpiece 122 connected to the casing 120 (that embodies the micro filter 118) includes an extension 124. The extension 124 facilitates mounting of a straw 126 through which the user of device 100 can inhale the oxygen generated using the oxygen generator 100. The straw 126 is made of Effective Microorganisms (EM) ceramic of probiotics. The EM ceramic is composed of aluminium silicon oxide having an orthorhombic crystal structure.

[0039] In operation, the hand held e-cigarette shaped oxygen generating and air purifying device 100 is used in an assembled form as seen in FIG. 1 or 2. The user will preferably hold the device 100 using the handle 110a and place the straw 126 in his mouth for breathing/inhalation of oxygen. During breathing or inhalation, the check valve 104 (in fact the opening 104a present in the check valve 104) will open up and allow the atmospheric air to forcibly enter inside the device 100. The atmospheric air then passes though the suction body 102, particularly the filter 106 and casing 108. The filter 106 will filter the contaminant present in the atmospheric air entering the device 100. The atmospheric air is then forced to pass through the internal cylinder 114a having honeycomb perforated structure and react with the solid oxygen content present inside the solid oxygen filter 112 to generate inhalable oxygen while the user is breathing. Technically, Oxygen is generated by reaction of solid oxygen compounds such as calcium hydroxide, calcium oxide, potassium peroxide, calcium peroxide, magnesium peroxide, potassium peroxide, barium peroxide and sodium peroxide.

[0040] Among these, excess potassium oxide reacts with moisture and carbon dioxide at room temperature to generate oxygen as shown in the reaction formula below:

2KO2+H2O.fwdarw.2KOH+3/2 02

2K02+CO2.fwdarw.K2C03+3/2 02

[0041] That is, carbon dioxide is removed and oxygen is generated at the same time. In addition, the oxygen generated as shown above may oxidize formaldehyde to form formic acid to remove formaldehyde seen in the reaction formula below:

HCHO+½O2.fwdarw.HCOOH

[0042] The formaldehyde removal reaction by potassium superoxide does not generate formaldehyde again in a variable manner, so it is more efficient for removing harmful gases than activated carbon and may be more useful depending on the purpose of use.

[0043] At this time when the oxygen is being generated, if required, one can add fragrance to colorless and odorless oxygen by adding into the solid oxygen filter 112. Some examples of the fragrances include but not limited to menthol and nicotine. Further, once the oxygen is generated by reacting the atmospheric air with the solid oxygen contained insider the solid oxygen filter 112, the generated oxygen is further passed through the micro filter 118 to further remove contaminants present in the generated oxygen and prevent entry of moisture from outside environment. This dual filter (the micro filter 118 and solid oxygen filter 112) configuration ensures delivery of purified oxygen to the user breathing using the device 100. The solid carbon filter 112 used in the proposed invention provides a large reaction surface area (for atmospheric air to react with solid oxygen).

[0044] According to some embodiment, the proposed oxygen generator 100 may be usable with a breathing exercising mobile application communicatively coupled with the device 100 and the device 100 can be used by users to develop sound breathing/air inhalation pattern often required during air inhalation exercises.

[0045] While various embodiments of the present invention have been illustrated and described, it will be clear that the present 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 present invention, as described in the claims.
