BACKGROUND OF THE INVENTION The present invention relates to water ozonation equipment, intended for use in water metering devices and water purifying apparatus.

As it is known, ozone is a form of oxygen, composed of three oxygen molecules, being the most powerful oxidant and disinfectant used since 1893 as a disinfectant in drinking water. Ozone in combination with water has the advantage of removing the taste or smell of drinking water. In contact with waste water, ozone can disinfect and remove odors and color. Ozone cannot be stored and for this reason it must be generated and dissolved in water at the site, at a consumption rate.

Therapeutic ozonators are currently known, such as the one in document RO 122183, which is used in medical applications and which consists of a high voltage source, an ozone generator that is fed by an air pump or oxygen bottled from a container, from the ozone generator exiting through a corrosion-resistant hose and directed into a nozzle for surface applications, or into a porous disperser that disperses ozone into fine bubbles in a container that may contain various liquids.

The technical problem solved by the present invention is the ozonification of the drinking water stored in the tank of a doser or purifier, if the oxygen at the inlet is 21%, generating 100 mg / h and providing control of the ozonation process, remote updating and viewing of communicated data.

The ozonation equipment according to the present invention solves the technical problem, when used in water dispensers, being composed of an ozone generator that produces 500 mg of ozone per hour under ideal conditions of 100% oxygen (under normal use conditions with 21% oxygen at the entrance, equipment

The ozonation equipment is based on a microcontroller 12 with flash memory, EEPROM (non-volatile memory) and external EEPROM memory (non-volatile memory.

Ozonator A consists of an ozone generator 1 that produces 500 mg of ozone per hour under the conditions where we have pure oxygen at the inlet. if the oxygen at the input is 21%, 100 mg / h will be generated.

Using an air pump 2 with a flow rate of 2 liters / min, the air in the atmosphere is taken and pumped through a silicone tube 3 into the ozone generator 1. After the ozonation process is completed, pump 2 will run for a few more minutes. , to allow ozone to dissipate and to keep ozone residues in the tank.

The ozone generator 1 is an electronic device having an enclosure 1.1 connected to an inlet tube 1.2 and an outlet tube 1.3. The inlet tube 1.2 is connected to the air pump 2, receiving oxygen air from the atmosphere, and through the outlet tube 1.3 after the ozone production process, ozone air is released. The process is itself known and is based on the conversion of air to ozone through electrical discharges, using high voltages (corona discharges).

The ozonation process will operate daily after a preset program, which can last 10-15 minutes, configurable through the web interface F and communicated to the equipment through the GSM / GPRS C system.

Ozonator A also has an air filter 4, which is intended to prevent particles larger than 0.45 micrometers in the air from entering the water basin. In order to prevent the water in the basin from reaching the ozone generator 1, a sense valve 5 is provided, and to maximize the area of bubble generation, a spherical diffusion stone 6, a stone made of corundum, is used. during the period when the ozonation takes place, water consumption is not recommended, which is configurable period of 2017 00978

Switch B is an electromechanical switch that detects the presence of a water can 8 on the water dispenser 9. Switch B is installed inside the can 9 and positioned with the actuator part switch on the contact surface between the can 8 and Dispenser 9. Switch B is normally set open in the configuration when no canister is present on the dispenser, and set closed when a canister is present on the dispenser. By detecting the presence or absence of water bottle 8, one can count the number of drums that have been replaced / changed on the respective dispenser by updating an index. The index represents the total counter of the number of drums changed and is stored locally, on the equipment, in a non-volatile memory.

The GSM C communication system that the ozonation equipment according to the invention contains contains a quad-band GSM / GPRS (2G) modem, which uses a SIM card for bidirectional data exchange with the server.

The communication between the equipment and the S server is done by standard Internet protocols (TCP socket), where the equipment is a TCP client that connects to the TCP server, identified by IP / name and port.

The equipment can be configured locally, via a serial interface, to set the GSM / GPRS configuration parameters, the ozonation and operating program.

Also through this serial interface, the equipment can be diagnosed locally. The GSM module is also used to alert any equipment errors for the following components: air pump 2, ozone generator 1, internal clock D, or to detect the cause of the last restart of the equipment.

Through GSM C communication system the time and date can be updated remotely.
