Description

A kind of vibrating bin

Technical field

The utility model belongs to machinery manufacturing technology field, relates to a kind of vibrating bin.

Background technology

Along with the development of society, economic growth people's living standard impels the application of relevant electric cleaning series products such as electronic clean brush, electric toothbrush, electric shaver more and more universal also in continuous raising.In above-mentioned electric cleaning series products, all be unable to do without vibrating device, the main micromachine that adopts drives internal motivation transmission mechanism realization vibrating function at present.

Yet because such vibrating device mainly relies on the interaction of gear to realize rotating, not only the energy of Xiao Haoing is too much, consumption rate is high, and rotation process is not steady, thereby causes cost performance height, poor stability in the rotation process.In addition, also have that noise is big, drive mechanism shortcomings such as comparatively complexity and functional reliability be low.

So the problem at above-mentioned prior art exists is necessary to study, to provide simple in structure, functional reliability height, low cost of manufacture, the vibrating device that noise is little in fact.

Summary of the invention

For addressing the above problem, it is a kind of simple in structure that the purpose of this utility model is to provide, functional reliability height, low cost of manufacture, the vibrating bin that noise is little.

For achieving the above object, the technical solution of the utility model is:

A kind of vibrating bin comprises upper casing (1), the lower casing (10) that matches with upper casing (1), is installed on first, second bearing (2,9), first, second spring (3,6) between upper casing (1) and the lower casing (10), runs through axle core (8), magnetic receiver (5), the magnet (7) of first, second bearing (2,9) and shaker arm (4); Wherein, described axle core (8) two ends connect upper casing (1) and lower casing (10) respectively by first, second bearing (2,9), shaker arm (4) is fixedly mounted on a core (8) middle part, first, second spring (3,6) is installed on the left and right sides of shaker arm (4), and magnet (7) relies on magnetic receiver (5) to be fixed on the shaker arm.

Further, described axle core (8) two ends are nested together with the inner ring of first, second bearing (2,9) respectively, and are fixed in the upper and lower shell (1,10), thereby make a core (8) in the rotation of first, second bearing (2,9) about do at the center.

Further, described first, second spring (3,6) has identical physical parameter, and the axis of first, second spring (3,6) overlaps.

Further, described magnet (7) is ndfeb magnet, and it is installed on the magnetic receiver (5).

The utility model adopts the solenoid actuated shaker arm centered by the center of axle core, and the brachium of shaker arm is that radius is done movement in a curve, makes core left-right rotation on the fixedly center of circle of standard, thereby has improved vibration precision and the stationarity of vibrating bin; While as stopping means, can make shaker arm remain on optimum range with spring; In addition, it is rational in infrastructure, uses and installs simply, and stability is high, is applicable to electric cleaning series products such as electronic clean brush, electric toothbrush, electric shaver.

Description of drawings

Fig. 1 is structural representation of the present utility model.

The specific embodiment

In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.

In description of the present utility model, it will be appreciated that, term " on ", close the orientation of indications such as D score, " preceding ", " back ", " interior ", " outward " or position is based on orientation shown in the drawings or position relation, only be the utility model and simplification description for convenience of description, rather than indication or the hint device of indication or element must have specific orientation, with specific orientation structure and operation, therefore can not be interpreted as restriction of the present utility model.In addition, term " first ", " second " only are used for describing purpose, and can not be interpreted as indication or hint relative importance.

In description of the present utility model, need to prove that unless clear and definite regulation and restriction are arranged in addition, term " installation ", " linking to each other ", " connection " should be done broad understanding, for example, can be fixedly connected, connect integratedly, also can be to removably connect; It can be the connection of two element internals; Can be directly to link to each other, also can link to each other indirectly by intermediary, for the ordinary skill in the art, can concrete condition understand the concrete implication of above-mentioned term in the utility model.

Please refer to shown in Figure 1ly, the utility model vibrating bin includes upper casing (1), the lower casing (10) that matches with upper casing (1), be installed on first, second bearing (2,9), first, second spring (3,6) between upper casing (1) and the lower casing (10), run through axle core (8), magnetic receiver (5), the magnet (7) of first, second bearing (2,9) and shaker arm (4); Wherein, described axle core (8) two ends connect upper casing (1) and lower casing (10) respectively by first, second bearing (2,9), shaker arm (4) is fixedly mounted on a core (8) middle part, first, second spring (3,6) is installed on the left and right sides of shaker arm (4), and magnet (7) relies on magnetic receiver (5) to be fixed on the shaker arm.

Described axle core (8) two ends are nested together with the inner ring of first, second bearing (2,9) respectively, and are fixed in the upper and lower shell (1,10), thereby make a core (8) in the rotation of first, second bearing (2,9) about do at the center.

First, second spring (3,6) of same physical parameter is equipped with on described shaker arm (4) both sides, and the axis overlaps.In addition, the center of two blocks of magnet (7) and the center of electromagnet coil are consistent.

When vibrating bin is worked, the electromagnet energising, electromagnet can produce magnetic field, to being fixed on attraction and the repulsive force about magnet (7) generation on the shaker arm (4), shaker arm (4) is obtained centered by axle core (8), is the power of radius motion with the brachium.Shaker arm the right and left is equipped with first, second spring of identical parameters, and the center of two blocks of magnet of shaker arm and the center of electromagnet coil are consistent.When shaker arm (4) moves to a direction, first, second spring (3,6) of meeting compression movement direction, first, second spring (3,6) is when being compressed to certain-length, the power that shaker arm (4) obtains equates with the elastic force that first, second spring (3,6) produces, at this moment, shaker arm (4) has reached maximum position, can't continue to compress first, second spring (3,6), therefore, the motion amplitude of shaker arm (4) is under control, and makes shaker arm (4) remain on the optimum range that electromagnet can be controlled.

Meanwhile, when the magnetic field of electromagnet changed, shaker arm (4) was to the motion of another one direction, and first, second spring of another one direction (3,6) also can be compressed to certain-length.Because electromagnet adds the spacing of first, second spring (3,6) to the active force that shaker arm (4) produces, shaker arm (4) is swung in certain amplitude, simultaneously, shaker arm (4) also can drive a core (8) left-right rotation in certain amplitude.

The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
