Abstract
A magnetic core of a laser printer is provided. A plurality of protrusions are formed on a magnetic core body in the length direction. The protrusions include a developing protrusion and three collecting protrusions. The width of the developing protrusion is larger than that of each collecting protrusion. The structure that the plurality of protrusions are arranged on the magnetic core enables magnetic force of the magnetic core to be centralized on the plurality of protrusions, and the developing protrusion and the three collecting protrusions are separately arranged. Therefore, the magnetic core of the laser printer has the advantages of saving raw materials and having low production cost.
Description
Technical field:
The utility model belongs to the apparatus field of laser printing machine, and what be specifically related to is a kind of laser printer magnetic core.
Background technology:
Laser printer is to transfer to after adopting magnetic core that carbon dust is picked up to realize on the paper developing, and the magnetic force size of magnetic core has influenced the effect of developing to a great extent, and existing magnetic core is circular, and its magnetic force relatively disperses, and can't concentrate magnetic force absorption magnetic.
Summary of the invention:
To the defective that prior art exists, the purpose of the utility model provides a kind of above-mentioned defective that can overcome, and can concentrate the laser printer magnetic core of magnetic force.
The technical scheme that its technical matters of the utility model solution is taked is: a kind of laser printer magnetic core; Key is that the body of said magnetic core is formed with a plurality of convexities in the longitudinal direction; Described convexity comprises that protruding and a plurality of collection of developing is protruding, and the described protruding width that develops is greater than collecting protruding width.
The collection convexity that described body forms is three.
Described development is protruding to be provided with rounding with the collection convexity.
Adopt arc transition to connect between described a plurality of convexity.
The utility model be employed in the structure that many convexities are set on the magnetic core, the magnetic force of magnetic core can be focused on many convexity, and distinguishes the collection convexity of developing protruding and a plurality of is set, have the saving starting material, than the advantage of low production cost.
Description of drawings:
Fig. 1 is the utility model structural representation.
Fig. 2 is another embodiment synoptic diagram of the utility model structure.
Embodiment:
Extremely shown in Figure 2 like Fig. 1; A kind of laser printer magnetic core; The body 1 of said magnetic core is formed with a plurality of protruding 10, described protruding 10 in the longitudinal direction and comprises develop a convexity 11 and a plurality of collection convexities 12, and the width of the described convexity 11 of developing is greater than the width of collecting convexity 12.To the absorption of carbon dust, the suction of the magnetic core that its suction is more circular than whole piece was big, can effectively must improve development effect when the described convexity 11 of developing can be used for showing, the quality of printing is high.The magnetic direction of whole piece magnetic core is concentrated, and has optimized the orientation of magnetic pole, has low cost of manufacture, the advantage of material saving.Described convexity can be provided with 3 to 8 as required.Wherein the width of a convexity is bigger, is the convexity of developing.Remaining is protruding for collecting, and collects the protruding carbon dust that is used for absorbing redundant.
Preferably, the collection protruding 12 of described body 1 formation is three.
Described development protruding 11 is provided with rounding with collection protruding 12.The convexity of rounding setting has good looking appearance, has the transitional good advantage of magnetic force.
Adopt arc transition to connect between described a plurality of protruding 10.Each convexity that adopts arc transition to connect can make protruding magnetic force more concentrated.
Claims (4)
1. laser printer magnetic core; The body (1) that it is characterized in that said magnetic core is formed with a plurality of convexities (10) in the longitudinal direction; Described convexity (10) comprises that one is developed protruding (11) and a plurality of collections protruding (12), and the width of described develop protruding (11) is greater than the width of collecting protruding (12).
