<p>The present invention provides an apparatus for generating micro-bubbles. the apparatus generates the micro-bubbles by increasing transfer pressure during a process of transferring fluid in which air and water are mixed in order to divide air, contained in water, into the micro-size. The apparatus has a simple structure and thus can be economically provided at low costs. Moreover, the apparatus can increase space utilization and thus provides convenience of use. The apparatus includes: a supply pipe (3) which supplies water to a pump; a discharge pipe (4) which discharges water; and an injector (5) which injects air into the discharge pipe (4). The injector (5) is formed by joining a first body (8) connected with the discharge pipe (4), and a second body (9). An outer side of the second body (9) is inserted into an inner side of one end portion of the first body (8) to contact and be fitted to each other with respect to the other end portion connected with the discharge pipe (4) in the first body (8). An induction hole (10), which communicates with the outside to supply air from the outside, is formed to a joining surface on which the first body (8) is joined with the second body (9) by insertion. An insertion hole (110), formed to supply air from the outside to the induction hole (10), is formed on the first body (8). A unidirectional check valve (12) capable of preventing backflow of air is formed on the injection hole (11). A bubble generation pipe (13), which has a diameter smaller than that of an outlet pipe (6) and thus has a narrow space, is connected with an end portion of the outlet pipe (6) connected to the second body (9).</p> |
