Abstract
The Vibrating motor includes stator, rotor and electric brush. One end of shaft of rotor is inserted into the electric brush fixed inside the stator, and the other end through the stator passes out of the casing. Grease stored up zone for sealing stored grease is setup inside stator bearing at position near to the divided copper. The grease stored up zone seals gap between shaft and stator bearing primely so as to keep cleaning liquid from filtrating into stator.

Embodiment
Below by accompanying drawing preferred embodiment of the present invention is described.
As shown in Figure 1, vibrating motor 1 comprises: by shell 2, fixing in the enclosure magnetite 3 and be installed in the wherein stator 5 that constituted of the bearing 4 of an end of shell; Be fixed on stator 5 other ends and the brush station parts 8 of brush station 6 and brush 7 are installed; And by commutator 9, coil 10, commutator 11, rotating shaft 12 and the rotor 14 that divides copper 13 to constitute, wherein commutator 9, coil 10 and commutator 11 all are enclosed within the rotating shaft 12, and an end of rotating shaft 12 inserts brush station parts 8, and the other end is through to shell 2 outsides and fixing with minute copper 13 through bearing 4.Electric current flows into from brush 7, to coil 10 energisings, makes that electromagnetic force takes place between magnetite 3 and the coil 10 to interact, and causes rotor 14 to rotate through commutator 9 thus.Divide in the off-centre that is fixed in rotating shaft 12 under the effect of copper 13, vibrating motor 1 begins vibration.
As shown in Figure 2, the bearing 4 of stator 5 is provided with the inserting hole 15 that rotating shaft 12 is passed.Inserting hole 15 is accumulating district 17 near the grease that divides copper 13 1 ends to be provided with salable preservation grease.In this inserting hole 15, rotating shaft 12 and grease accumulate the district and a Zhe dynamic component 16 are set between 17, and the two ends of rotating shaft 12 are rotated by this Zhe dynamic component 16 and brush station 6 clampings respectively.
The grease of storage grease accumulates district's 17 Zhe dynamic friction that not only reduced between Zhe dynamic component 16 and the rotating shaft 12, but also can prevent to infiltrate the slit that cleaning fluid leaves between rotating shaft 12 and Zhe dynamic component 16 in the clean processing of vibrating motor 1.
In the present embodiment, the bearing 4 and the magnetite frame of stator 5 are made of the thermoplastic resin material, thereby by cylindrical housing 2 being put into the casting mold of placing cylindrical shape magnetite 3 and being injected the integrally formed stator that obtains of thermoplastic resin material that constitutes bearing 4.
In the assembling process of the vibrating motor 1 of said structure, at first be pressed into commutator 11 in the rotating shaft 12 and coil 10 is installed, the rotating shaft 12 of installing commutator and coil is inserted into the brush station 6 interior also riveteds of brush station parts 8 in brush station parts 8, subsequently grease is injected grease and accumulate district 17 and said modules is inserted the integrally formed stator of making, will divide the copper riveted at last to rotating shaft 12.
The grease of storage grease accumulates district 17 when Zhe dynamic component 16 is carried grease, the infiltration of cleaning fluid in the time of also can preventing to clean vibrating motor 1.The same with prior art, rotating shaft 12 ends relative with minute copper are covered by brush station parts 8, so prevented that also cleaning fluid from infiltrating from here.
In the present embodiment, bearing 4 is integrally formed with interior other parts of stator, and is made by resin material, but this execution mode does not constitute limitation of the invention.In fact, also can accumulate district 17 near dividing copper 13 sides that grease is set at oiliness bearing.
Fig. 3 is the generalized section of the vibrating motor of installation another embodiment of the present invention.Fig. 4 is the generalized section of vibrating motor internal stator shown in Figure 3.Among Fig. 3 and Fig. 4 with Fig. 1 and Fig. 2 in identical parts adopt identical label to represent.
As shown in Figure 3, vibrating motor 1 comprises: by shell 2, fixing in the enclosure magnetite 3, magnetite cover 21 and be installed in the wherein stator 5 that constituted of the oiliness bearing 22 of an end of shell; Be fixed on stator 5 other ends and the brush station parts 8 of brush station 6 and brush 7 are installed; And by commutator 9, coil 10, commutator 11, rotating shaft 12 and the rotor 14 that divides copper 13 to constitute, wherein commutator 9, coil 10 and commutator 11 all are enclosed within the rotating shaft 12, and an end of rotating shaft 12 inserts brush station parts 8, and the other end is through to shell 2 outsides and fixing with minute copper 13 through bearing 4.Electric current flows into from brush 7, to coil 10 energisings, makes that electromagnetic force takes place between magnetite 3 and the coil 10 to interact, and causes rotor 14 to rotate through commutator 9 thus.Divide in the off-centre that is fixed in rotating shaft 12 under the effect of copper 13, vibrating motor 1 begins vibration.
As shown in Figure 4, the magnetite of stator 5 cover 21 and bearing 4 are provided with the inserting hole 15 that rotating shaft 12 is passed.Between oiliness bearing 22 and magnetite cover 21, be provided with grease and accumulate district 17.The two ends of rotating shaft 12 are respectively by oiliness bearing 22 and brush station 6 clampings and rotate.
In the vibrating motor clean,, accumulate and distinguish at 17 o'clock and can't be continued to flow into by its retardance so the cleaning fluid that infiltrates arrives grease because cleaning fluid can only infiltrate from the gap between rotating shaft 12 and the oiliness bearing 22.
In the assembling process of this structural vibrations motor 1, at first be pressed into commutator 11 in the rotating shaft 12 and coil 10 be installed, the rotating shaft 12 of installing commutator and coil be inserted in the brush station 6 of brush station parts 8 and riveteds in brush station parts 8.Subsequently stator 5 is inserted in the brush station parts 8.Before inserting, the magnetite of stator 5 cover 21 is pressed in the shell 2 in advance and accumulates district 17 to grease and inject grease, is pressed into oiliness bearing 22 subsequently and constitutes stator 5.
When cleaning vibrating motor, the grease of storage grease accumulates the cleaning fluid that has blocked infiltration in district 17 and further flows.The same with prior art, rotating shaft 12 ends relative with minute copper are covered by brush station parts 8, so prevented that also cleaning fluid from infiltrating from here.
