Abstract: Ozone supplier switchable by gaseous fluid comprises (i) a hollow housing (10) comprising a receiving chamber, (ii) an air inlet (20), (iii) an ozone outlet opening (30), which is arranged at other point of the housing, (iv) a discharge tube (40) comprising a connecting end (41) and a discharge end, (v) an ozone generator comprising an air inlet tube, an ozone outlet tube and an ozone generating body, (vi) a fluid sensor, which is arranged between the air inlet and the ozone generator, and (vii) a controller, which is arranged in the receiving chamber of the housing. Ozone supplier switchable by a gaseous fluid comprises (i) a hollow housing (10) comprising a receiving chamber, (ii) an air inlet (20), which is arranged at a point outside or inside the housing, for introducing the outside air, (iii) an ozone outlet opening (30), which is arranged at other point of the housing and provided in a check valve for preventing backflow, (iv) a discharge tube (40) comprising a connecting end (41) and a discharge end, (v) an ozone generator comprising an air inlet tube, an ozone outlet tube and an ozone generating body between the air inlet tube and the ozone outlet tube, (vi) a fluid sensor, which is arranged between the air inlet and the ozone generator, and (vii) a controller, which is arranged in the receiving chamber of the housing and is electrically connected with the induction circuit board and the ozone generator. The connecting end is connected with the ozone outlet opening. The discharge end extends to a target object, which has suction action. The discharge tube generates negative pressure. The ozone discharge tube is connected with the ozone outlet opening. The ozone generator is arranged in the receiving chamber of the housing and generates ozone. The fluid sensor comprises (a) a vertically arranged tubular body comprising a lower inlet opening, an upper outlet opening and a guide zone between the upper outlet opening and the lower inlet opening, (b) a movable magnetic inductor element, which is movable up and down in the guide zone of the tubular body, and (c) an induction circuit board with a hall element, which is arranged on one side of the induction circuit board. The upper outlet opening is connected by a connecting tube to the air inlet tube of the ozone generator. The lower inlet opening is connected with the air inlet. A magnetic body is arranged on one side of the movable magnetic inductor element. The movable magnetic inductor element is suctioned under a reduced pressure, and increased. The magnetic body lies opposite to the hall element, when the movable magnetic inductor element is raised. The hall element generates an induction signal. The controller activates the ozone generator body of the ozone generator, when the controller receives the induction signal from the hall element. The controller deactivates the ozone generator body of the ozone generator, when the controller receives no induction signal from the hall element.
