MICRO AIR BUBBLE-GENERATING APPARATUS, AND BATHTUB SYSTEM USING SAME

The present invention relates to a micro air bubble-generating apparatus and to a bathtub system using same, and more particularly, to a micro air bubble-generating apparatus in which an air bubble-generating part is prevented from being clogged to lengthen the lifespan of the apparatus, and which exhibits excellent performance in generating a large volume of micro air bubbles. The micro air bubble generating apparatus of the present invention comprises a main body (10), and a cap (20) coupled onto the main body (10). The main body includes: a pressure pipe (11), one side of which is connected to a pipeline, and the inside of which has a space for the inflow of water and air at a predetermined pressure; a nozzle (13) mounted onto one end of the pressure pipe (11), and which has a reduced diameter to increase the flow velocity; an expansion pipe (14) having a gradient, and which is connected to the nozzle (13) such that the diameter thereof gradually increases from the end of the nozzle (13); and an explosion pipe (15) connected to the end of the expansion pipe (14) such that the diameter thereof is increased from the end of the expansion pipe (14), and which has an explosion space (S). The cap (20) has a coupling portion (22) coupled to the explosion pipe (15), and a discharge pipe (21) arranged in the cap (20) which communicates with the explosion space (S). The thus-configured air bubble-generating apparatus can be installed in a bathtub, a dishwasher, a food washer for washing vegetables, fruits, and the like, a medical instrument washer, an air bubble-generating system for a farm, a red tide prevention system, etc., to be used for a wide variety of purposes such as bubble bathing, washing, etc. L'invention concerne un appareil de production de microbulles d'air et un système de baignoire utilisant ledit appareil. L'invention concerne, plus particulièrement, un appareil de production de microbulles d'air dans lequel on empêche l'encrassement d'une partie de production de bulles d'air afin de prolonger la durée de vie de l'appareil, ce dernier présentant d'excellentes performances dans la production d'un grand volume de microbulles d'air. L'appareil de production de microbulles d'air de l'invention comprend un corps principal (10), et un couvercle (20) couplé au corps principal (10). Ledit corps principal comprend : un tuyau de pression (11) dont un côté est relié à un pipeline, et dont l'intérieur présente un espace pour le débit entrant de l'eau et de
