Connection member [0033] I: Air inlet [0034] O: Clean air outlet [0035] D1: Channel width [0036] D2: Duct width [0037] D3: Outlet tube width [0038] D4: Outlet tube length [0039] The air purifier (1) comprises a body (2) having an air inlet (I) through which the air in the environment is sucked and a clean air outlet (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. [0040] The air purifier (1) of the present invention comprises at least one microbubble generator (4) having [0041] an air inlet port (5) which provides the delivery of the air sucked into the body (2) to the CO.sub.2 adsorption unit (3), [0042] a liquid inlet port (6) which provides the delivery of the basic liquid solution to the CO.sub.2 adsorption unit (3), [0043] a duct (7) where the air and the basic liquid solution are mixed, [0044] a channel (8) which delivers the air from the air inlet port (5) to the duct (7) such that the basic liquid solution and the air are mixed, and [0045] an outlet tube (9) through which the air-basic liquid solution mixture is taken into the CO.sub.2 adsorption unit (3).

[0046] The air purifier (1) of the present invention comprises at least one microbubble generator (4) which enables the basic liquid solution and the air the in the environment to be mixed so as to be delivered to the CO.sub.2 adsorption unit (3). By means of an air inlet port (5) and a liquid inlet port (6) provided on the microbubble generator (4), the air and the basic solution enter the microbubble generator (4) through separate lines. The channel (8) which delivers the air is arranged at the air inlet port (5). The microbubble generator (4) further comprises a duct (7). Said duct (7) has a width narrower than the width of the liquid inlet port (6), and the air flowing through the channel (8) and the basic solution taken through the liquid inlet port (6) meet first time at the duct (7) and get mixed. Thus, microbubbles are formed in the liquid-air mixture due to pressure, and the resulting mixture is transferred to the CO.sub.2 adsorption unit (3) through the outlet tube (9). The microbubbles forming in the mixture increase the efficiency of the reaction occurring between the basic solution and the carbon dioxide in the air, thus ensuring that a higher amount of carbon dioxide is converted to carbonate so as to clean the air.

[0047] In an embodiment of the present invention, in the microbubble generator (4), the width (D2) of the duct (7) is three to five times the width (D1) of the channel (8). Thus, the microbubbles generated in the microbubble generator (4) have the optimum dimensions for improved reaction efficiency.

[0048] In an embodiment of the present invention, in the microbubble generator (4), the width (D3) of the outlet tube (9) is 10 to 15 times the width (D1) of the channel (8). Thus, the microbubbles generated in the microbubble generator (4) have the optimum dimensions for improved reaction efficiency.

[0049] In an embodiment of the present invention, in the microbubble generator (4), the length (D4) of the outlet tube (9) is 40 to 50 times the width (D1) of the channel (8). Thus, the basic solution-air mixture formed in the microbubble generator (+) can be efficiently delivered to the CO.sub.2 adsorption unit (3) by maintaining the bubbles.

[0050] In an embodiment of the present invention, the air purifier (1) comprises at least one air delivery tube (10) having at least one nozzle (12) which can be connected to the air inlet port (5) at the microbubble generator (4). Thus, the air sucked into the body (2) is transferred to the microbubble generator (4).

[0051] In an embodiment of the present invention, the air purifier (1) comprises a connection member (14) which connects at least two air delivery tubes (10). Thus, a plurality of microbubble generators (4) can be connected to a plurality of air delivery tubes (10) respectively. Moreover, the volume of air cleaned in unit time in the air purifier (1) is increased.

[0052] In an embodiment of the present invention, the air purifier (1) comprises at least one liquid delivery tube (11) which can be connected to the liquid inlet port (6) at the microbubble generator (4). By means of the liquid delivery tube (11), a plurality of microbubble generators (4) can be connected side by side in series.

[0053] In an embodiment of the present invention, the air purifier (1) comprises at least one flow separator (13) which regulates the flow of the air-basic liquid solution mixture in the CO.sub.2 adsorption unit (3). Thus, the liquid-air mixture with bubbles coming from the microbubble generator (4) is prevented from further mixing in the CO.sub.2 adsorption unit (3) such that the size of bubbles is prevented from increasing.

[0054] By means of the present invention, an air purifier (1) is realized, with increased carbon dioxide adsorption capacity and rate.
