Unit, useful for supplying ozone in a tap for purification and sterilization of drinking water, comprises housing, air inlet portion, ozone output opening, and outlet conduit with connection end and free end that extends to target

摘要

The unit (5) comprises a housing (10) with a hollow space, an air inlet portion placed inside or outside the housing to guide the outside air, an ozone output opening located in another portion on the housing and comprising a check valve for output of the ozone; and an outlet conduit comprising a connection end (41) and a free end (42), where the connecting end is connected to the opening. The free end extends to a predetermined target (6) for ozone, where the target guides the flow of ozone so that the outlet conduit generates a negative pressure. The unit (5) comprises a housing (10) with a hollow space, an air inlet portion placed inside or outside the housing to guide the outside air, an ozone output opening located in another portion on the housing and comprising a check valve for output of the ozone; and an outlet conduit comprising a connection end (41) and a free end (42), where the connecting end is connected to the opening. The free end extends to a predetermined target (6) for ozone, where the target guides the flow of ozone so that the outlet conduit generates a negative pressure. An ozone generator is located in the space of the housing for generating ozone, and comprises an air guidance part, an ozone delivery part, and an ozone production part located between the guidance part and the delivery part. The ozone delivery part is connected to the ozone output opening. An air inlet member is located between the air inlet portion and the ozone generator. A guide tube is placed vertically in the ozone generator, and comprises a lower input end, an upper output end, and a guiding portion located between the ends. The upper outlet end is connected to the air guidance part of the ozone generator by a connecting tube, and the lower input end is connected to the air inlet portion. An active magnetic inductor is arranged in the guide portion of the guide tube in a state that it is adapted to be raised. A magnetic body is attached to one side of the active magnetic inductor. The inductor is driven in a floating state when the outlet conduit is in the negative pressure state. An induction circuit card with a hall component is placed on a side of the guide tube, where the hall component is placed on a side of the induction circuit card. A magnetic body is aligned with the hall component, when the inductor is in the floating state, so that the hall component generates an induction signal. A cross section of the guide portion of the guide tube is rectangular, square, elongated or polygonal. A cross section of the inductor is defined correspond to that of the guide portion, so that the condition of raising of the inductor can be achieved safely and the magnetic body on the inductor can be oriented normal to the hall component. The active magnetic inductor is equipped with ventilation-through portions that are formed with ventilation through holes penetrating the inductor magnetic working material or spaced ribs formed on the periphery of the inductor. The ventilation-through portions are formed by a space between the spaced ribs, where the ribs come into contact with the guide portion of the guide tube, which reduces frictional resistance of the inductor towards its lifting state. A filter assembly is arranged on the air inlet portion.
