Detailed description of the invention
Embodiment 1, as shown in Figures 1 to 4, the Electro-static Driven Comb structure of a kind of electric blower, including the dust bag 7 that the casing 1 being provided with air outlet 12 is connected with air outlet 12, casing 1 is provided with main handle 11, and dust bag 7 is provided with earth lead 6, is electrically connected by electric installation between casing 1 with dust bag 7.Casing 1 is laid with and draws electric lead 15 for what guide electrostatic in casing 1, draw electric lead 15, earth lead 6 is connected with electric installation, the earth terminal of earth lead 6 directly contacts with ground, electrostatic is directly released in the earth by earth lead 6, and electrostatic is completely resolved to the harm that machine and operator bring.
Further, the earth terminal of earth lead 6 is provided with metallic ground parts 9.The purpose installing these metallic ground parts 9 is to increase the weight of earth lead 6, it is to avoid earth lead 6 is blown afloat, and increases the contact area of earth lead 6 and ground simultaneously, makes Electro-static Driven Comb more reliable.Metallic ground parts 9 can have the metal of excellent conductive performance with copper, aluminum etc. and make, and shape can be rectangular ring or circular, or triangle ring-type etc..
Wherein, electric installation includes metallic conductive element 2 and metal conducting bar 5, and metallic conductive element 2 is fixed on air outlet 12 place, and the bag mouth of dust bag 7 is connected with air outlet 12 by fixed mount 4, and metal conducting bar 5 is arranged on fixed mount 4.Owing to being demountable structure between casing 1 and dust bag 7, therefore between metallic conductive element 2 and metal conducting bar 5, it is provided with electrical connecting element, after casing 1 is installed with dust bag 7 combination, metallic conductive element 2 is connected by electrical connecting element with metal conducting bar 5, earth lead 6.Casing 1 is formed by left and right two halves structure split is fixing, two halves structure mosaic, left and right is die joint, metallic conductive element 2 is generally fixed on the die joint of air outlet, this is owing to the electrostatic of electric blower is mainly in the upper generation of casing 1 (spiral case), and electrostatic is concentrated mainly on the die joint of air outlet, therefore metallic conductive element can directly by the Electro-static Driven Comb on the die joint of air outlet.
It addition, in the present embodiment, electrical connection element adopts metal torsion spring 3, metal torsion spring 3 transfer in casing centrally through bearing pin 13, the first end of metal torsion spring 3 contacts connection with metallic conductive element 2, and the second end of metal torsion spring 3 contacts connection with metal conducting bar 5.The purpose arranging metal torsion spring 3 is easy for using fractionation, makes to be in during Electro-static Driven Comb line work Elastic Contact connection status.
Concrete, metallic conductive element 2 is U-shaped, and the first end of metallic conductive element is provided with and draws the hook that electric lead 15 is connected.Wherein, draw electric lead 15 and can re-extend into the die joint at casing main handle place or the metal shell surface 14 of motor.Although electrostatic is concentrated mainly on air outlet die joint, but motor, main handle die joint place are likely to and have partial electrostatic, and therefore wire can extend also to discharge the electrostatic being likely on motor housing, main handle place die joint assemble further.Second end of metallic conductive element is provided with and the bending part of torsion spring Elastic Contact, and after casing separates with dust bag, bending part no longer stops torsion spring foot, and the another foot of metal torsion spring can be upspring and be kept unsettled.
During machine operation, dry leaves or tiny dust rub with spiral case sidewall and fan blade under the high speed of fan blade is stirred and produce electrostatic, the electrostatic produced can gather in the metallic conductive element 2 being fixed on spiral case air outlet die joint, then pass through contact and sequentially pass through metal torsion spring 3, metal conducting bar 5, earth lead 6 and metallic ground parts 9, in the earth finally discharged.
In this embodiment, the connection member in Electro-static Driven Comb circuit is metal conductive materials, and concrete metal can adopt aluminum, copper etc. to conduct electricity very well, metal suitable again on cost, and such electrostatic can be directly released in the earth through these conductive metal material on fast and reliable ground；The plating nickel on surface of metallic conductive element, metal conducting bar, metal torsion spring and metallic ground parts processes, it is to avoid the abrasion caused in use and corrosion.
Embodiment 2, as shown in Figures 1 to 4, on the basis of embodiment 1, earth lead 6 is fixed on dust bag 7, specifically can suture the hiding band 71 of a strip, earth lead 6 traverse from hiding band 71 on dust bag 7, both conceal earth lead 6, also the exposed potential safety hazard brought of wire is avoided, meanwhile, dust bag 7 is provided with the traction 8 extended out, and traction 8 extends out from the bottom of dust bag 7, the earth terminal of earth lead is passed from traction 8, makes earth lead 6 entirety stash.
Concrete, traction 8 exceeds the length of dust bag 7 more than 40 millimeters, earth lead 6 part is hidden in be hidden in band 71, remainder is hidden in traction 8, such fixed mount 4, metal conducting bar 5, dust bag 7, earth lead 6, traction 8 and metallic ground parts 9 are merged into a global facility, this global facility and casing can split, and facilitate operator to use, make electric blower more humane.
By increasing the problem that traction 8 solves the necessary scrape along the ground ability release electrostatic of dust bag in this embodiment, earth lead 6 can also be hidden and increase the bonding strength of earth lead 6, concurrently set the safe length of traction to the operator meeting various height use time release circuit can keep and earth surface, electrostatic is completely resolved to the harm that hair-dryer and operator bring.
As the deformation of above-described embodiment, above-mentioned dust bag 7 can be replaced with other dust collect plant, such as directly connects a dust leg at air outlet, then be connected with refuse receptacle by dust leg.And above-mentioned electric installation and electrical connecting element can also use conductive component conventional at present, for instance conductor wire, various metallic conductor are replaced, as long as realizing corresponding conducting function.
