DETAILED DESCRIPTION

[0022] The disclosure attempts to radiate substances contained in the two generation boxes containing hydrogen peroxide and deionized water with ultraviolet light and makes them react with a substance that may generate hydroxyl radicals for physical-chemical chain reactions.

[0023] Low electric conduction and ultrasonic dissolution have three functions (decomposing water molecules, generating chitin resonance and fining water particles to generate cold vapor). When air flow passes through the generation boxes and filter elements, it can promote mixing and extracting of their contained substances and generate the Venturi effect to carry the contained substances to pass through a titanium dioxide channel. In such process, hydroxyl radicals, water, oxygen, hydrogen peroxide and ozone of the contained substances are separated and discharged into the air for sterilizing and cleaning the surrounding environment.

[0024] Therein, chitin starts to resonate with pillbug of chitin exoskeleton due to its resonance frequency, so it is particularly suitable for killing the pillbug.

[0025] The disclosure is further described in conjunction with accompanying drawings and embodiments as follows.

[0026] By reference to FIG. 1, a device for cleaning and purifying air and body surface comprises an outer shell, and further comprises: 1, a fan/air blower; 2, an ozone generation unit and circuit; 3, a generation box 1; 4, a mixing channel; 5, a generation box 2; 6, a cover; 7, a Venturi channel; 8, a main air channel; 9, a UV/LED lamp; 10, a Peltier condensation structure; 11, liquid; and 12, a suction core.

[0027] Chemical reactions generated in the device are shown in Table 1.

[0028] The device comprises a combination of a hydroxyl radical generation structure and the Peltier condensation structure therein. The device comprises the air control part 1 for an air inlet that sucks air from an exterior connected to the propeller fan.

[0029] As shown in FIG. 3, air enters the main air channel 8 through the air control part and firstly passes through the Peltier condensation structure 10.

[0030] The Peltier condensation structure comprises a Peltier in the middle and also comprises a supply circuit. When a current flows through the Peltier, the two sides of the Peltier dissipate heat and absorb heat. As shown in FIG. 2, due to the heat absorption of the left side of the Peltier, vapor in the air flowing near the left side of the Peltier is condensed. Meanwhile, the condensation structure comprises a collecting unit, such as airtight porous sponge, configured to collect condensed water drops,

[0031] Due to the heat dissipation of the right side of the Peltier, it generates a large quantity of heat to provide stream of hot air flow, which is supplied out of the device by another fan. Thus, the temperature of surrounding air of the device will be raised.

[0032] The device comprises the two generation boxes, namely the generation box 1 and the generation box 2, configured to contain a solution, preferably peroxide water (hydrogen peroxide) and low-electric-conductivity deionized water with no carbonate or bicarbonate contained.

[0033] Ozone is generated by the ozone generation unit and circuit 2 with built-in ceramic electrodes and a built-in boosted circuit. The volume of ozone generated in the channel may be controlled by adjusting an activation time of the boosted circuit and a diameter of nozzles fixed to the electrodes (electrode areas), and thus ozone is captured to confirm to a volume of optimum standard demand. The ozone is driven by the fan 1 to pass through a central channel after being generated. Part of gas may be sucked into the generation box 1 based on the generated Venturi effect of the device. The generation box 1 contains hydrogen peroxide, vapor and oxygen. Therefore, the ozone is mixed with and reacts with these contained substances to generate gas of oxygen and ozone free radicals O°, H° and OH°.

[0034] Generated gas in the generation box 1 together with air and ozone in the main air channel enters the mixing channel 4 coated with titanium oxide, and at the moment, the UV/LED lamp 9 at the upper portion of the main air channel illuminates the mixing channel to activate more hydroxyl radicals. The gas of the main channel area is sent into the generation box 2 by the Venturi effect and discharged into exteradonal air by the top ultrasonic decomposition atomization unit of the generation box 2 together with the gas in the generation box 2.

[0035] The generation box 2 also contains liquid contained substances such as deionized water and hydrogen peroxide, and O.sup.2 generated therein sufficiently reacts with ozone and hydrogen peroxide in a specific space through Venturi reaction air flow. Meanwhile, an ultrasonic generation piezoelectric sensor (converting electric energy into mechanical energy) with an atomizing function is added into the generation box 2 and disposed on its top, which is coated with TiO.sub.2. It is known that the final mixed gas in the generation box 2 also generates more hydroxyl radicals.

[0036] The generation box 2 comprises a piezoelectric membrane. When ultrasonic waves of the piezoelectric membrane are conducted to the generation box 2, the contained liquid is absorbed by the ceramic core and decomposed ultrasonically through physical-chemical reactions for ultrasonic decomposition so as to be ionized into hydroxyl radicals OH°/H°O in a high oxide environment.

[0037] An ultrasonic wave generation part of the piezoelectric membrane of the generation box 2 supplies ultrasonic waves by a shell body at the upper portion of the generation box 2 for vibration for ultrasonic decomposition. An electrical part is further disposed and comprises a supply circuit and an oscillator providing another ultrasonic decomposition frequency, consistent with a chitin frequency and thus generates resonance to easily eliminate pillbug.

[0038] The generation box 2 is further equipped with the suction core 12 that is a suction part configured to capture the liquid in the generation box 2 and pump the liquid onto the piezoelectric membrane by a capillary effect. The core, preferably cellulose, extracts the contained liquid.

[0039] The piezoelectric membrane has a frequency of 15 Khz to 10 Mhz and has three effects of (i) ultrasonic decomposition, (ii) resonance with chitinous substances for weakening frameworks of mildew and yeast and eliminating aforementioned harmful substances, and (iii) atomization of the liquid from the generation box 2.

[0040] A UV/LED lamp 9 is further disposed on the top of the generation box 2.

[0041] The generation box 1 may be equipped with a suction core and a piezoelectric membrane like the generation box 2 or may be coated with TiO.sub.2 and illuminated by the UV/LED lamp 9 in the same way. Therefore, the two generation boxes individually have a gas generation condition of H.sub.2O.sub.2+H.sub.2O+O.sub.3+O.sub.2.

[0042] Such free radicals are added to other free radicals such as OH° or hydroxyl radicals and groups generated by an ozone decomposition effect to create reactive reactant conditions. In conjunction with air flowing and ultrasonic radiating of less than 390 nm, when vapor, oxide water, ozone and oxygen pass through the mixing channel 4 coated with TiO.sub.2 to be dispersed in the air, their generated hydroxyl radicals are mixed with various ions as much as possible in the air so as to disperse anions, which simulates disinfection by promotion of laminar flow from the interior of equipment.

[0043] In preferred embodiments, air flow for driving ozone by the main air channel 8 and vapor, oxygen and hydrogen peroxide extracted in the generation box 1 by the Venturi effect converge and are added into the mixing channel 4. The mixing channel 4 is coated with TiO.sub.2, and meanwhile the UV/LED lamp 9 is disposed at an inlet of the mixing channel 4 and may illuminate the mixing channel with lamplight, so that the mixing channel generates more hydroxyl radical. Then, the generated gas of the mixing channel is mixed up in the atomization physical-chemical reactions of the generation box 2, which are illuminated by the UV/LED lamp disposed on the generation box 2, and meanwhile the tail end of the generation box 2 is coated with TiO.sub.2.

[0044] The device of the disclosure comprises an electric or optical detecting unit configured to control a UV wavelength. A wavelength that the device may have could be, as shown in Table 1, 254 nm, 190 nm or less than 242 nm.

[0045] The device of the disclosure comprises concave parts for containing the generation box 1 and the generation box 2. In addition, the concave parts may allow these boxes to be inserted and placed in a device body and may provide connection and power for the generation boxes, thereby supplying power to the piezoelectric membranes for ultrasonic decomposition and atomization and controlling the piezoelectric membranes.

[0046] Logistically, there is always a generation of anions for generating ozone by high voltage in all corona effects, but under the control of a concentration of 100,000 pcs/cc to 10,000,000 pcs/cc, ozone is discharged through a propeller, a Venturi pipe and a mixed reaction and discharge pipeline at a concentration controlled at 0.001-0.05 ppm in an output distance of 5 cm by propelling an air flow rate, while a concentration of hydroxyl radicals is controlled at 1,000,000 pcs/cc to 20,000,000 pcs/cc.

[0047] In the device, at a position 5 cm away from the ozone generator, a volume of ozone is 0.0001 g to 0.5 g, and an evaporation capacity of H.sub.2O.sub.2 is controlled within a range of 0.001 g to 0.5 g, and a concentration of hydroxyl radicals is 500,000 pcs/cc to 20,000,000 pcs/cc.

[0048] In consideration of a current set standard limit (WEL) of hydrogen peroxide of 1.4 mg/m.sup.3 (1 ppm), an equivalent of the level of hydroxyl radical is (1.4 mg/m.sup.3)/(34 g/mol)=0.0000411 mol/m.sup.3.

[0049] By numerical calculation, a quantity 0.0000411 mol/m.sup.3×6.23×10.sup.23=2.56×10.sup.19 molecules/m.sup.3 is acquired. If each hydrogen peroxide molecule generates two free radicals (1), a quantity 2.56×10.sup.19×2=5.12×10.sup.19/m.sup.3 is acquired, which is equivalent to the maximum radical yield of 5.12×10.sup.13/mL.

[0050] Then, a quantity (0.008 mols)×(6.023×10.sup.23)×2=9.63×10.sup.21 is acquired by calculating generated free radicals according to reactions of interadonal gas and hydrogen peroxide in the disclosure, and if the device continuously works within 60 days, 1.6×10.sup.20 free radicals are acquired every day in average.

[0051] If an interadonal operation area is 300 m.sup.3 large, a daily yield of free radicals is 1.6×10.sup.12/300 m.sup.3=5.33×10.sup.17 free radicals/day/m.sup.3, which is equivalent to a quantity 5.33×10.sup.11/mL of free radicals every day.

[0052] The purification and hydroxyl radical generation device of the disclosure may transmit free radicals 0°, H° and OH° and generate these free radicals by different reactions to disinfect and clean a whole large indoor space. The device of the disclosure may acquire the maximum number of free radicals and remove radon in the air to the maximum extent to sufficiently purify and disinfect air and surface and heat air, thereby creating comfortable living conditions.

[0053] It should be understood that although the disclosure has been described as above and precise structures shown in accompanying drawings, they are not intended to limit the disclosure. Various modifications and variations can be made without departing from the scope of the disclosure. The scope of the disclosure is only limited by claims.
