Embodiment
The present invention has disclosed a kind of needle-emitting rack of ion fan, as Fig. 1, Fig. 2 and shown in Figure 3, the punch block 2 that comprises emission needle 1 and installation emission needle 1, be provided with annular ring on punch block 2, in this preferred embodiment, be provided with two annular rings on punch block 2, be respectively annular outer ring 3 and annular inner ring 4, certain ordinary circumstance only establishes an annular outer ring 3 or annular inner ring 4 also can.
Be equipped with cannelure 6 on one side end face of annular outer ring 3 and annular inner ring 4, this cannelure 6 is provided with the end cap with cannelure 6 sealings, and described end cap is respectively outer end cap 7 and the inner end cap 8 that connects with described annular outer ring 3 and annular inner ring 4.
Described annular inner ring 4 is fixedly connected with annular outer ring 3 by a transverse arm 5; And described transverse arm 5 is provided with and holds the conduit 14 that wire 13 is drawn.Many emission needles 1 inwardly are set on annular outer ring 3, on annular inner ring 4, many emission needles 1 outwards are set.For improving the performance of ion blower, most advanced and sophisticated first circular trace that forms of each emission needle 1 head on annular outer ring 3, most advanced and sophisticated second circular trace that forms of each emission needle 1 head on annular inner ring 4, the first circular trace and the second circular trace are concentric circles, and the large 0mm～15mm of radius of radius ratio second circular trace of the first circular trace.What illustrate is, when the first circular trace equated with the radius of the second circular trace, the head tip of each emission needle 1 all was arranged in the same face of cylinder, can greatly reduce like this loss of charge in discharge process.
The position of each emission needle 1 that corresponding week makes progress uniform of described annular outer ring 3 and annular inner ring 4 is provided with a conductive sleeve 9, offers vertically conductive jack 10 on this conductive sleeve 9, is provided with shell fragment 11 in this conductive jack 10.Described conductive sleeve 9 axially is placed in cannelure 6 along the radial direction of annular outer ring 3 and annular inner ring 4 with it; All be covered with Gold plated Layer or silver coating on the appearance of conductive sleeve 9, conductive jack 10 inside and shell fragment 11.Described each emission needle 1 afterbody is inserted into the interior electrical connection of conductive jack 10 and fixing, and is coated with one deck insulating case 12 on the needle body of emission needle 1, only makes its head exposed.
Respectively lay the wire 13 of an astragal insulation sheath in two cannelures 6, this two wire 13 is electrically connected to each conductive sleeve 9 welding on a circle, and two wire 13 ends draw from cannelure 6, and just in time conduct connects the power connection end of power supply.
In the present invention, the design of described annular outer ring and annular inner ring comprises following three kinds of situations:
(1), be provided with simultaneously annular outer ring and annular inner ring on punch block.
(2), only be provided with annular outer ring on punch block.
(3), only be provided with annular inner ring on punch block.
About the magnitude setting of annular outer ring and annular inner ring, ordinary circumstance only establishes an annular outer ring or/and annular inner ring, but also can a plurality of annular outer rings be set as required or/and annular inner ring.
Certainly, when gold-plated or silver-plated on outer peripheral face, conductive jack inwall and shell fragment to conductive sleeve, better enforcement is first to install shell fragment 11 on conductive sleeve 9, then all covers upper Gold plated Layer or silver coating on whole surface with making in the golden liquid of its whole immersion or silvering solution.Press the common call of electronic applications, can claim that conductive sleeve is golden finger or silver finger.
The present invention compared with prior art has the following advantages:
(1) adopt conductive sleeve that emission needle is electrically connected to wire, have Gold plated Layer or silver coating on conductive sleeve, emission needle is connected with the conductive sleeve plug, on the basis that guarantees the emission needle easy accessibility, has guaranteed that further the electric conductivity that is electrically connected to is good.
(2) because the present invention has substituted copper ring of the prior art with the wire of tape insulation crust, the protection of insulation sheath is arranged because of wire, longer service life can not damaged substantially, and wire 13 also decreases on cost for the standard component outsourcing gets final product.
(3) conductive sleeve is directly to be installed on punch block by clamping structure, and conductive sleeve both conducted electricity, and and for example needle stand of the prior art is equally fixed emission needle, the such parts of needle stand have been avoided increasing again, reduce amount of parts, more simplified the structure, be more convenient for assembling.
(4) the present invention controls to differ between the most advanced and sophisticated most advanced and sophisticated formation of each emission needle head second circular trace that forms on the first circular trace and annular inner ring of each emission needle head on annular outer ring and is of a size of 0mm～15mm, thereby significantly improved the performance of ion blower, improved this Parameter stability of balanced voltage.The larger problem of emission needle frame noise that exists in prior art simultaneously can reduce because the emission needle frame inner ring is enough little noise in the present invention greatly.
The present invention still has multiple concrete execution mode, and all employings are equal to replacement or equivalent transformation and all technical schemes of forming, within all dropping on the scope of protection of present invention.
