[0031] The elements illustrated in the figures are numbered as follows: [0032] 1. Air purifier [0033] 2. Body [0034] 3. CO.sub.2 adsorption unit [0035] 4. Cylindrical body [0036] 5. Inlet tube [0037] 6. Air outlet tube [0038] 7. Wall [0039] 8. Helix member [0040] 9. Channel [0041] 10. Lower plate [0042] 11. Top plate [0043] 12. Basic solution outlet tube [0044] I: Inlet opening [0045] O: Clean air outlet opening

[0046] The air purifier (1) comprises a body (2) having an inlet opening (I) through which the air in the environment is sucked and an outlet opening (O) through which the cleaned air is released, and a CO.sub.2 adsorption unit (3) which is provided on the body (2), which chemically adsorbs the carbon dioxide in the air taken into the body (2) by being supplied with air together with a basic solution and which has an inlet tube (5).

[0047] The air purifier (1) of the present invention comprises the CO.sub.2 adsorption unit (3) having at least one helix member (8) forming a passageway in the CO.sub.2 adsorption unit (3) for the basic solution-air mixture moving through the inlet tube (5).

[0048] In the air purifier (1) of the present invention, the air in the environment is taken into the body (2) by means of an inlet opening (I). The air taken into the body (2) is delivered to the CO.sub.2 adsorption unit (3) together with a basic solution by means of a pump. The CO.sub.2 adsorption unit (3) is a section where the air and basic solution mixture reacts, and as a result of said reaction, the carbon dioxide gas in the air in the environment is adsorbed by the base and converted into carbonate. By means of the helix member (8) of the CO.sub.2 adsorption unit, the basic solution-air mixture contact time (reaction time) prolongs, and thus the basic solution is enabled to adsorb a higher amount of carbon dioxide.

[0049] In an embodiment of the present invention, the air purifier (1) comprises the CO.sub.2 adsorption unit (3) having at least two inlet tubes (5), a wall (7) which is placed between the inlet tubes (5) and which separates the air-basic solution flow taken from each inlet tube (5), and at least two helix members (8) through which the air-basic solution mixture taken from each inlet tube (5) can flow without mixing with each other. Thus, the bubbles in the air-basic solution do not join with each other such that the risk of the formation of a larger bubble and decreasing the efficiency of the reaction is prevented. Moreover, by means of different inlet tubes (5), air-basic solution mixtures at different or same flow rates can be delivered to different helix members (8) through separate passageways.

[0050] In an embodiment of the present invention, the air purifier (1) comprises the CO.sub.2 adsorption unit (3) having a cylindrical body (4) and a helix member (8) which is placed into the cylindrical body so as to contact the wall of the cylindrical body (4). In this embodiment, the helix member (8) contacts the cylindrical body (4) as a single piece or by snap-fitting, and since there is no gap therebetween, the air-basic solution mixture moves through the helix member (8) in a smooth flow.

[0051] In an embodiment of the present invention, the air purifier (1) comprises the CO.sub.2 adsorption unit (3) having a lower plate (10) which covers the cylindrical body (4) from one end, inlet tubes (5) which are disposed onto the lower plate (10) at equal degrees, and a helix member (8) provided in a number equal to the number of inlet tubes (5). Thus, the air-basic solution mixture is delivered to the CO.sub.2 adsorption unit (3) in a smooth flow from each inlet tube (5), ensuring a more efficient reaction.

[0052] In an embodiment of the present invention, the air purifier (1) comprises the CO.sub.2 adsorption unit (3) having a helix member (8) which has a length almost equal to the length of the cylindrical body (4). Thus, the path the air-basic solution mixture follows in the helix member (8) starting from the inlet tube (5) is extended, increasing the efficiency of the reaction.

[0053] In an embodiment of the present invention, the air purifier (1) comprises the CO.sub.2 adsorption unit (3) having an upper plate (11) which covers the cylindrical body (4) from another end, and at least one air outlet tube (6) which is disposed on the upper plate (11). Thus, the clean air of which the carbon dioxide is adsorbed rises and flows towards the clean air outlet opening (O) on the body (2) through the air outlet tube (6) without requiring any extra guidance (pump, etc.).

[0054] In an embodiment of the present invention, the air purifier (1) comprises a basic solution outlet tube (12) which is provided on the lower plate (10) and a channel (9) which connects the basic solution outlet tube (12) and the air outlet tube (6) and which is disposed at the center of the helix member (8). Thus, the solutions remaining and forming as a result of the air-basic solution reaction are quickly transferred from the CO.sub.2 adsorption unit (3), without entering the helix member (8) again, to another receptacle to be processed with acid to be neutralized.

[0055] In an embodiment of the present invention, the air purifier (1) comprises the CO2 adsorption unit (3) having a helix member (8) which is manufactured from a polymeric material, preferably from polypropylene. Thus, the basic solution is prevented from damaging the CO.sub.2 adsorption unit (3).

[0056] By means of the present invention, an air purifier (1) is realized, wherein the reaction efficiency and time are increased and a higher amount of carbon dioxide in the air is adsorbed.
