Multiple terminals kation anion generator
The present invention relates to air cleaning unit technical fields, more particularly, to a kind of multiple terminals kation anion generator.
Kation anion generator has obtained very big popularization at present.But the grain that common kation anion generator is discharged
Subgroup is often difficult to cover larger range, and concentration reduces, efficiency is lower.
Summary of the invention
In view of the deficiency of the prior art, the object of the present invention is to provide a kind of generations of multiple terminals negative ions
Device, it has the characteristics that negative ions group can be released on a large scale.
To achieve the goals above, the technical scheme adopted by the invention is that: multiple terminals kation anion generator, including shell
Body, the interior high voltage direct current that is equipped with of the shell export device, which, which exports device, has positive terminal and anode connector, described
The cathode metal band and negative metal band that 2 are parallel to each other are additionally provided in shell, be fixed on the cathode metal band it is several to
The positive carbon fiber brush of upper extension is fixed with several cathode carbon fiber brush upwardly extended on the negative metal band, together
When, one end of the cathode metal band is electrically connected to the positive terminal, and one end of the negative metal band is electrically connected the anode connector, just
Pole carbon fiber brush and cathode carbon fiber brush correspond to two-by-two.
The spacing of the adjacent positive carbon fiber brush is in that shape is gradually reduced.
After adopting the above structure, the invention has the advantages that compared with the prior art: can release on a large scale just
Anion group.Using parallel-connection structure is divided, multiple groups carbon fiber brush is connected in parallel on positive and negative multiple terminals kation anion generator of the invention
The end of DC high-voltage power supply can release negative ions group on a large scale.After tested, the negative ions group's concentration discharged is
At least the 130% of other usual manners.
Detailed description of the invention
Present invention will be further explained below with reference to the attached drawings and examples:
Fig. 1 is the in-built perspective view of the multiple terminals kation anion generator of the embodiment of the present invention.
10, high voltage direct current exports device, 11, positive terminal, 12, anode connector；
21, cathode metal band, 22, negative metal band；
31, positive carbon fiber brush, 32, cathode carbon fiber brush.
Embodiment, as shown in Figure 1: multiple terminals kation anion generator, including shell (being not shown on figure) are set in the shell
There is high voltage direct current to export device 10.In general, the input terminal of high voltage direct current output device 10 uses 220V alternating current.The high pressure
DC output devices 10 have positive terminal 11 and anode connector 12.
The cathode metal band 21 and negative metal band 22 that 2 are parallel to each other are additionally provided in the shell.The cathode metal band 21
On be fixed with several positive carbon fiber brush 31 upwardly extended, be fixed with and several upwardly extend on the negative metal band 22
Cathode carbon fiber brush 32.Meanwhile one end of the cathode metal band 21 is electrically connected to the positive terminal 11, the negative metal band
22 one end is electrically connected the anode connector 12.Positive carbon fiber brush 31 and the corresponding formation one two-by-two of cathode carbon fiber brush 32
To effect terminal.Divide parallel-connection structure in this way, using, multiple groups carbon fiber brush is connected in parallel on the end of positive and negative direct current high voltage power supply,
Negative ions group can be released on a large scale.
The spacing of adjacent positive carbon fiber brush 31 is in that shape is gradually reduced.That is, with the trend of electric current, adjacent anode
The spacing of carbon fiber brush 31 is gradually reduced.Equally, with the trend of electric current, the spacing of adjacent cathode carbon fiber brush 32 by
It is tapered small.After tested, after using such setting, the ion concentration at each position can preferably keep balancing.
The above description is only a preferred embodiment of the present invention, is not intended to limit the scope of the invention, all utilizations
Equivalent structure or equivalent flow shift made by description of the invention and accompanying drawing content is applied directly or indirectly in other correlations
Technical field, be included within the scope of the present invention.
