Filter provided by the invention further includes sterilizing function, and the function in sterilizing chamber is washed by being provided with electrode 37 To realize, if electrode uses platinum tantalum electrode, ion species can efficiently and stably generate activity from thin water by electrolysis Oxygen kind, i.e. ozone (O3) or hydrogen peroxide (H2O2)。
At this time, following reaction occurs in anode electrode:
2H2O→4H++O2+4e-
Meanwhile following reaction occurs:
3H2O→O3+6H++6e-
2H2O→O3+4H++4e-,
So as to generate ozone (O3)。
In addition, following reaction occurs in cathode:
4H++4e-+(4OH-)→2H2+(4OH-)
O2 -+e-+2H+→H2O2
Make the O of generation by electrode reaction2- combined with the H+ in solution, generation hydrogen peroxide (H2O2)。
Produced by being powered to platinum tantalum electrode into the big ozone of sterilizing power (O3) and hydrogen peroxide (H2O2), can make containing These ozone (O3) and hydrogen peroxide (H2O2) electrolyte.Ozone in the electrolyte or the concentration of hydrogen peroxide are adjusted to Make the concentration of the inactivations such as virus, electrolyte can be bypassed air through, virus swum in air etc. can be inactivated.In addition, foul smell leads to Cross and dissolved with the ozone in electrolyte or hydroperoxidation and ionization, so as to eliminate the foul smell in air.
When needing to sterilize, and providing cleaned air to mask at the same time, it is necessary to set ozone decomposed device on plenum duct, The present invention is preferably setting ozone decomposed device on filter screen.
During by being electrolysed tap water and (cathode) heap scaliness on the electrode, electric conductivity reduces, it is difficult to continues to be electrolysed.This When, make the polarity upset of electrode (by the positive and negative switching of electrode) be effective.Carried out by regarding cathode electrode as anode electrode It is electrolysed and the incrustation scale being piled up on cathode electrode can be removed.Depending on can be using such as timer in polarity upset control Phase overturns, can also when each operating starts upset etc. and aperiodically overturn.Alternatively, it is also possible to detect the upper of electrolytic resistance (Faradaic current reduces or decomposition voltage rises) is risen, polarity upset is made based on the result.
Filter provided by the invention further includes atomizing functions, the function by bottle body bottom be provided with vibrating reed 38 come Realize.When needing to be atomized aqueous solution, when being powered up in vibrating reed 38, bottle lower part 11 vibrates, and makes the water in bottle lower part Or aqueous solution atomization.
Filter provided by the invention further includes heating function, and the function in bottle body bottom or periphery by setting heater To realize.
In use, the water either depth of sodium-chloride water solution water or aqueous solution is injected in the inner cavity of bottle lower part 11 Be higher than the height of the exhausting-gas hole of bottle lower part 11, the annular groove then filter screen 14 being caught in bottleneck, covers bottle cap, by face Air admission hole on cover is connected on the exhausting-gas hole of plenum chamber by tracheae, then mask is applied to user's face.At this moment selection is started Switch, selecting switch of the invention have the function of seven, are respectively:" filtering ", " sterilization ", " spraying ", " filter sterilization ", " filtering spraying ", " sterilization spray " and " filter sterilization spraying ", when selecting " filtering " function, air pump 28 and air pump 32 start work Make, extraneous air enters inlet plenum by the air admission hole on bottle top 12, and air is by air pump 28 by the indoor air of air inlet It is pumped on bottle lower part 11 in the annular chamber 19 on bottom, the air in annular chamber 19 is discharged into by multiple admission lines on stack shell Into filtered fluid, bubble is formed, bubble enters the cylindrical cavity on bottle top to the bottleneck floated on bottle lower part 11 It is interior, then by filter screen filtration, most water mists are removed, will be discharged into by the cleaned air of washing by annular bottleneck cavity To plenum chamber, clean air is drained into mask and the cavity of people face formation by air pump 32 by the tracheae connected with mask again It is interior, so that what people breathed is clean air.
Mobile air purifying device provided by the invention is using water or aqueous solution as filtration media, by dust, rubbish When various microorganisms, the overwhelming majority when air pump 28 is drained into water is dissolved, is locked in water or aqueous solution with bacterium, or Person directly inactivates bacterium, dust mite, avoids unclean net air from being sucked by human body, so that make one suction is clean as forest Air.
Embodiment two
Fig. 4 is the axial sectional diagrammatical view illustration for the Portable water filter that second embodiment of the invention provides;As shown in figure 4, One entirety is formed at the bottle lower part 11 and bottle top 12 for the Portable water filter that second embodiment of the invention provides, other Structure is identical with first embodiment.Here no longer repeat.
On the basis of any filtration device structure of above-described embodiment one to two, inlet plenum exhaust outlet and plenum chamber into Check valve is set at gas port, and such each road tracheae may not necessarily do too thin.If it should also be noted that, eliminate inlet plenum In air pump or plenum chamber in air pump, the present invention still can implement.
If in addition, it by matrix is Ti (titanium) that the electrode 37, which is, the electrode plate that clad is made of Ir (iridium), Pt (platinum), The current value for flowing through the electrode 38 is set as that current density is number mA/cm2~tens of mA/cm2.In detail, if by above-mentioned Electrode 37 is powered to sodium-chloride water solution, then following reaction occurs in cathode electrode:
4H++4e-+(4OH-)→2H2+(4OH-)
And following reaction occurs in anode electrode:
2H2O→4H++O2+4e-
Meanwhile following reaction occurs for the chlorion contained in solution:
2Cl-→Cl2+2e-
In addition, the Cl2Reacted as follows with water:
Cl2+H2O→HClO+HCl。
Therefore, the big HClO of sterilizing power (hypochlorous acid) is produced by being powered to electrode 37, makes the disease swum in air Poison etc. inactivates.In addition, the foul smell in air also reacts with hypochlorous acid and ionizes and dissolve, the foul smell in air is thus removed.
Water filter provided by the invention can also sterilize mist directly to indoor or in-car provide, and filter screen is removed, And sodium-chloride water solution is injected in sterilizing chamber is washed, open air intake pump, electrode slice, vibrating reed, heater and/or air delivery pump work Make, water filter becomes sterilization spray device, and in-car or interior can be sterilized.
Mobile filtration apparatus provided by the invention can also become the sprayer for the treatment of respiratory disease, and filter screen is gone Fall, the injection of medicine aqueous solution in sterilizing chamber is washed, makes air intake pump, vibrating reed, heater and/or pump work of supplying gas, water filtration Device becomes anti-inflammatory sprayer, and the medicine water mist sprayed is sucked by respiratory system, so as to reach the effect cured the disease.
The present invention is described in detail above in association with attached drawing, but specification is only for what is interpreted the claims.But this Protection scope of the present invention is not limited to specification.Skill of any one skilled in the art in present disclosure In the range of art, the change or replacement that can readily occur in, should be covered by the protection scope of the present invention.Therefore, it is of the invention Protection domain should be subject to the protection domain of claims.
