APPLICATION FIELD [001] “OZONIZED WATER AND OZONE DISPENSER IN SYSTEM

NON-RECIRCULANT ”, belonging to the household appliances sector to distribute sanitization products, refers to a liquid dispenser, preferably water, or ozonated air in a non-recirculating system for sanitizing food and surfaces or small environments.

STATE OF THE TECHNIQUE [002] Contamination can be defined as the introduction into the environment (water, air, food, surfaces, etc.) of pathogenic microorganisms in concentrations harmful to human health. On a daily basis, usually the main sources of contamination are fresh foods purchased at fairs and supermarkets and manual contact with contaminated objects and, more sporadically, contamination of environments with fungi, for example in cabinets, wardrobes and drawers .

[003] In general, the main form of food hygiene, mainly vegetables, fruits and vegetables, is washing with bleach containing sodium hypochlorite or chlorination, which usually leaves a bad smell; and hand cleaning is done with water and soap or alcohol.

[004] A more modern and environmentally applied form of hygiene is through the application of ozone.

[005] When ozone is used in water, it has many benefits for our health. According to VELANO et al. (VELANO, HELENA ENGEL et al. “In vitro evaluation of the bacterial activity of ozonated water against Staphylococcus aureus”, Pesqui Odontol Bras, v.15, n.1, p. 18-22. Jan-Mar 2001 ), ozone for being highly oxidizing is able to break the cell wall of bacteria and fungi, inactivating these microorganisms and preventing them from being able to

2/11 cause damage to health, noting that Staphylococcus aureus is part of the skin and mucous microbiota, but is also associated with diseases such as abscesses, bacteremia, endocarditis and osteomyelitis, in addition to being resistant to multiple drugs, ozone can be used to disinfect utensils, in water for disinfection through the oxidation of organic and inorganic compounds, foods such as fruits, vegetables and vegetables and fish, these also because of their ability to reduce odor. Table 1 presents a comparison of the characteristics of the chlorination and ozonation processes.

Br.), With concentrations of 0.5, 1.0 and 1.5 mg / L for 1 minute during minimum processing compared to chlorine. In this study it was found that ozone effectively reduced contamination by molds and yeasts. At the end of the analysis period, the ozone-treated groups had an average population of molds and yeasts that was significantly smaller than the groups treated with chlorine.

The results showed that all treatments suppressed the initial number of total and aerobic psychrotrophic coliforms. In all three treatments the results were positive, increasing the shelf-life from 1.5 to 3 days, with small changes in oxidative rancidity and color. For fish fillets treated with 10 ppm of ozone, there was an increase of 25% in life time.

[0010] Ozone in the form of gas can also be applied to sanitize small environments, such as cabinets, wardrobes, drawers and shoe racks, in order to eliminate bad odor.

SUMMARY OF THE INVENTION [0019] Equipment designed to produce and inject ozone gas into liquids (including water), ozonizing them through a transfer system via air compressor and porous stone forming microbubbles, thus being called non-recirculating system.

[0020] Formed by two parts interconnected by a quick coupling, the ozone generating equipment is mounted on the base where the mobile part is supported, constituted in a reservoir equipped with spray nozzle, porous stone for the formation of microbubbles and pressure escape.

[0021] The equipment has its parts coupled via quick couplings made of ozone-resistant materials, preferably Teflon, stainless steel and aluminum, and has the following characteristics:

- Ozone concentration generated from 0.5 g / Nm ³ to 1 g / Nm ³ ;

- The equipment has a 4-position switch on the panel, which clockwise increases ozone production and counterclockwise decreases ozone production.

[0022] The novelties and improvements in functionality of the “OZONIZED WATER AND OZONE DISPENSER IN NON-RECIRCULATING SYSTEM” consist of using an autonomous mini compressor to supply air to obtain ozone; ozone is not injected under pressure into the liquid reservoir, but in the form of bubbling through a porous stone immersed in that reservoir; the ozonation of the liquid is not done by recirculating water, but by the bubbling of the ozone generated; the connection between the ozone-generating part and the dispenser is made by quick coupling, facilitating handling; use of a hole in the dispenser, acting as a “chimney”, to escape undissolved gases; and, use of catalytic destructor for the

DETAILED DESCRIPTION OF THE INVENTION [0027] Formed by two parts, base and dispenser, interconnected by a quick coupling, the ozone generating equipment is mounted on the base where the movable part is supported, constituted in a reservoir equipped with spray nozzle, porous stone for formation of microbubbles and pressure escape.

[0028] The base of the equipment consists of a box with a lower extension where the sprinkler is supported, and these two parts are coupled to the top via quick coupling made of ozone-resistant materials, preferably Teflon, stainless steel and / or aluminum.

[0029] Outside the base box, there is a wire with a plug (6) for connection to the 110 or 220 V mains and the equipment's control buttons, which consist of an on-off switch (7), a button “Starf (2A) to start the equipment operation, a four position manual switch (3D) for regulating the amount of ozone to be produced and the connection to the dispenser, made by a quick coupling (4C), as shown in Figure 1A. Internally, properly and structurally supported from the base of the equipment, a micro air compressor (1) is located, with capacity

Petition 870170020907, of 03/29/2017, p. 15/25

9/11 35 liters / hour; high voltage coil (3A) with typical capacity of the order of 30 KVy a command transformer (1A), with a capacity of 0.2 W; a catalytic-type ozone destroyer (5), a low frequency ozone generator circuit (3), a dielectric (3B); and a micro controller circuit (2), which gives access to the “starf” control buttons (2A) and manual ozone regulator (3D), as shown in Figures 1C and 1A. To operate on 110 V or 220 V electrical current, there is a 20 VA autotransformer, which only has the function of using the micro air compressor (1) at 110V or 220V, not acting on the operation of the rest of the circuit generator or microcontrolled.

[0030] In terms of safety in relation to high voltage, the high voltage coils (3A) must have the high voltage insulation cable well insulated and thick, and this cable must be directly connected inside the dielectric, that is, it it must enter about 3 cm inside the dielectric and inside the borosilicate glass, being 100% protected.

[0031] The dispenser is formed by a water reservoir (4), preferably in the conical trunk shape, which contains a porous stone (4D) internally and close to the bottom connected to the sprinkler (Figure 1B), as shown in Figure 1A. The sprinkler (Figure 1B), which is threaded into the water reservoir (4), as shown in Figure 1A, contains a sprinkler valve (4B); a small opening in its upper part acting as a pressure relief valve (4A) generated by the ozone gas formed and partially undissolved in the water; and, in its suction tube, an outlet for the introduction of the porous stone (4D) and an entrance for the ozonized water, as shown in Figure 1B.

[0032] The “OZONIZED WATER AND OZONE DISPENSER IN NON-RECIRCULATING SYSTEM” is powered by alternating current through the electrical network at 110 V or 220 V.

[0033] Initially the amount of ozone to be generated is regulated, between 0.5 g / Nm ³ and 1 g / Nm ³ by means of the manual ozone regulator (3D). When pressing the start button (2A) - start - the timer controlled micro circuit (2) - timer - is immediately activated for a period of 30 seconds, turning on the mini compressor

Petition 870170020907, of 03/29/2017, p. 16/25

10/11 air (1) and the low frequency ozone generator circuit (3), which in turn generates a signal that excites the high voltage coil (3A), generating the necessary voltage for the dielectric (3B) , through the corona effect, produce ozone in the regulated and desired quantity, through the manual regulators (3D) existing on the ozone generator circuit board (3), as shown in the dotted line flow of Figure 2.

[0034] During this time of 30 seconds, the oxygen present in the compressed air generated by the mini air compressor (1) will pass through the dielectric (3B), which will be producing the corona effect, transforming into ozone, being transported by the current of compressed air to the porous stone (4D), which is immersed inside the reservoir with water (4) and will emit tiny bubbles of air + ozone dissolving them in the water. After the 30 seconds of ozone injection in the water, it will be ozonized and ready for the spray nozzle (4E) of the reservoir to make it available in the form of water spray with dissolved ozone, as shown in the full line flow in Figure 2.

[0035] After the 30 seconds of the programmed time, the equipment turns off and waits for a new connection (start) to restart the process.

[0036] When turned off after use, small amounts of residual ozone may remain in the internal pipes, which may, over time, damage or destroy the mini compressor (1), partially composed with rubber, having as protection for this fact of a catalytic ozone destroyer (5) before this return, which will effectively maintain the integrity of the mini compressor (1).

[0037] The water reservoir (4), which is also used as a sprinkler for ozonated water, is manual and removable for each application, being again filled with water for new operation until a “maximum level” marking. The water reservoir (4) has a quick coupling connection (4C) to easily be connected and removed from the ozone generating equipment. The spray nozzle (Figure 1B) also has a small hole (4A) in its part

[0038] All materials and parts of the dispenser are state of the art and found commercially.

[0039] In the intention of using the “OZONIZED WATER AND OZONE DISPENSER IN NON-RECIRCULATING SYSTEM” aiming at the elimination of odors and “sanitization” by ozone in places of small volumes, such as cabinets, shoe racks and small places of a residence, to The base of the equipment must be placed without the dispenser in place and then turned on for a few times, the place being then properly closed for the action of the generated ozone.
