As mentioned above, the form that control piece 25 can be simple double-pole switch is optionally to turn on and off electric current.Or control piece 25 can be potentiometer or rheostat 55 with controlling resistance (it also can be used as the location positioning sensor for the large change of hardness).For instance, when adjusting the control piece 25 of the form be rheostat 55 and electric current with the amount selected according to rheostat 55 during by piezoelectric after active circuit, material deliquescing respectively.Therefore, user can allot (for instance) downwards and is applicable to applying the hardness (very soft and tool is flexible) of 20 Shore A of object.After the diameter with relatively soft applies cosmetics, rheostat can be readjusted with (for instance) and be produced the hardness of 72 Shore D with combing and the separated relatively hard applicator of the applicable eyelashes of realization by user.Higher hardness in Shore D scope will allow applicator by scraping blade and effectively scrape, but the ability in Shore A scope can give the certain capabilities (especially in being immersed in mascara and then by after mascara scraping blade) that firmer brush does not have by lower hardness.For instance, harder brush can be elongated and curling, but denseization particularly well.More soft brush can be gone up dress and smear compared with multi-product and therefore denseizationr, but can produce more caking or can be as hard brush be modifiable " modification " well.The intrinsic flexibility that can optionally allot permission user between hardness can not provide with single conventional brush approaches has ready conditions or changes and apply situation gradually.This kind of flexible example can be adjusted brush and apply the different step in process to carry out.First step can be with mascara denseization eyelashes and upper dress, and this can benefit from soft brush.Second step is to make crimping eyelash, this will benefit from harder hardness, and third step can be, and with adamantine hardness, by eyelashes, separated (this step itself is for to the unusual poor efficiency of dress general on eyelashes, because step is for this reason because its rigidity can pull off the most of mascara filling on it.
Although above discuss in the context of piezoelectric, other material can provide hardness, shape, volume or directed selective reaction to change.Term " selective reaction material " means to be suitable for structurally changing in response to applying or removing of a certain amount of energy at least one any material in shape, volume, stiffness or orientation as used herein.For instance, selective reaction material can be piezoelectricity, ferroelectric or thermoelectricity reaction material.For instance, referring to books < < solid-state physics: (the 27th of the progress > > of research and application, Buddhist draws Derek plucked instrument hereby (Frederick Seitz), 1972) description to selective reaction material in, it is incorporated herein by reference to the overall.The example that represents the material of ferroelectric property is some nylon (for example nylon 5,10), poly-trifluoro-ethylene, and Kynoar (PVDF), and polymethyl methacrylate (PMMA).The example of thermoelectric material is those materials that comprise polar crystal.When these crystal are heated or cooled, pyroelectric effect occurs, thereby changes the polarity of crystal, and this forms the voltage of crossing over crystal.The particular instance that represents the material of pyroelectric effect is tourmaline, bone and tendon.The piezoelectric using can have positive piezoelectric modulus (for example PZT) or negative coefficient (for example PVDF).
Therefore, in one embodiment, be suitable for applying the applicator part that the applicator of cosmetics (for example mascara) comprises handle and extends from described handle.Described applicator partly has the applicator structure that comprises at least one the selective reaction material that is selected from piezoelectricity, ferroelectric or thermoelectricity reaction material.Described reaction material is suitable for changing in response to applying or removing of the energy of appropriate amount at least one in shape, volume, stiffness and the orientation of applicator structure.Also be provided for supplying or removing the member of the energy of described amount, and for optionally controlling the control member of the energy of the described amount that is fed to described selective reaction material or removes from described selective reaction material.Preferably, described selective reaction material is piezoelectric, and more preferably, described piezoelectric is piezoelectric ceramics material.
According to the present invention, described applicator part can comprise any applicator structure that is applicable to applying cosmetics, for example (for instance) there is brush, rod, spatula, powder puff, comb or the roller of bristle.As used herein, term applicator structure can comprise as the whole applicator part in any one in previous examples, or can refer in whole or in part any part of applicator part, for example the pointed tooth of the molded brush of (for instance) institute is, the surface of bristle, spatula or roller or the loose structure of powder puff that twisted wire is brushed.Described applicator part can have be suitable for dress, carry, apply, one or more surface of exfoliating, frosted, finishing and polishing.Described surface can by space, groove, indentation etc. strengthen to promote cosmetics upper dress, carry and apply.
The energy of described amount is the one being selected from electric energy, kinetic energy, heat energy, magnetic energy or luminous energy.Ferroelectric material has permanent magnetic moment.Even in the situation that do not exist and affect the magnetic moment that its external magnetic field (as family expenses magnet) exists ferroelectric material.Can be using the energy of described amount (for instance) as alternating current or direct current be directly fed to reaction material, maybe can supply using described energy as energy field electric field or the magnetic field for example for example, via known circuit or assembly (coil), set up.When piezoelectric is photoactivation shape-memory polymer (LASMP), can with the form of light, provide optical energy from incandescent lamp bulb, laser instrument, light emitting diode (LED) or other suitable sources.
Piezoelectric can at least one fiber form provide.Described material alternately provides or is provided as with laminar form presses layer or rod stock, and it is to be a significant benefit to specifically to guide after stiffness changing occurs material by the shape how moving and opposed external force is thereon reacted.Related fiber also can be any shape profile.It can be rod, " C " or " U " shape, S shape, tubular, triangle or trilobal, square, any other polygon etc.
Can there are several different flexible ceramic configurations in applicator.Describe mascara applicator herein, but the applicator of other type and cosmetic surface (for example (for instance) brush, rod, spatula, powder puff, comb, exfoliating, depilation, frosted, finishing or polished surface) can any number mode be incorporated to the material that responds.For instance, spatula can have at least one surface being made by reaction material thin slice.Described material can be through arranging to cause spatula " become cup-shaped " in response to the change of electric current or flatten, or represent rigidity or flexible change to a certain degree.
For mascara application, can construct like that applicator by the conventional twisted wire brush of extraordinary image, that is, it can consist of a plurality of extrusion fibers that are twisted into brush along axis traditionally.Adding power supply and circuit changes to realize.If use fiber, brush can be entirely piezoelectricity (for example, pottery) fiber so, or is piezoelectric fabric and the mixing of conventional fibre for certain effects.Can by the one in two lines from handle or handle bar being attached to the far-end of mascara brush, be implemented to the electricity of the piezoelectric of extrusion fiber, wherein another line is attached to the substrate that is embedded in the line in handle or handle bar.
Applicator can be by pointed tooth, tooth, thread surface or is of value to the capable or array of one or more flexible ceramics of other geometry applying and forms.These pointed tooths or tooth can be several microns on length and/or width, until be 30mm in length.Applicator can have the conventional plastics pointed tooth that does not change hardness being embedded in flexible ceramic surface, and this will allow pointed tooth when hardness changes because of the interpolation of energy " floating ".Flexible surface is that firm pointed tooth is supported in basis wherein.When applying energy, it is more soft or harder that described basis can become, thus allow pointed tooth be applied in time bring into play independently function.The region that this basic material can be crossed over placement pointed tooth is constant thickness or density, or it can increase, reduce or have in addition to allow pointed tooth to have the condition of the change of different activity levels gradually.
Applicator can consist of flexible ceramic material completely, or the mixing for containing the conventional material (thermosetting plastics and/or thermoplastic polymer and elastomer, metal etc.) mixing with flexible ceramic component.This mixing can be by double injection (plastics and piezoelectric ceramics), insert-molded (surrounding the plastics of piezoelectric ceramics part) or by assembling (plastic tube in piezoelectric ceramics or have plastic tube or the piezoelectric ceramics in space) formation.Spendable additional plastic and elastomer also can be polyolefin, fluoropolymer and vinyl.
Applicable hardness range can be Xiao A hardness scope (more soft), Shore D hardness range (harder), Rockwell stiffness measurement district (the hardest) or crosses over any scope in any hardness simulation of any combination of scope mentioned above.The example of " rigidity " is: Shore rigidity is applicable to more soft or compared with the plastics of tool flexibility, rubber and elastomer; And Rockwell rigidity is applicable to measure " harder " plastics, for example nylon, acetal (Delrin), polystyrene (PS) or Merlon (PC).
When selective reaction material is (for instance) piezoelectric, it is by piezo-electric effect or via inverse piezoelectric effect performance function.Piezo-electric effect is the situation that the material of applicator stands the voltage of expansion and compression (it causes material to become through polarization) and generation opposite polarity; Any energy producing is proportional with the mechanical force that is applied to material.The change that voltage moves due to dipole (owing to being applied to the mechanical energy of material) forms.
When applicator material stands electric field, inverse piezoelectric effect occurs, and the in fact expansion of the polarity based on field or contraction of material, and this effect is also proportional with the intensity of electric field.For optimal mode (inverse piezoelectric effect), we will be applied to material the voltage of the identical polarity of the polarizing voltage with material (it is for being applied to 'inertia' pottery (for instance) material so that the voltage of its piezoelectricity).When this voltage is applied to mascara brush fiber, its length will correspondingly narrow down the diameter of increase and fiber.If apply identical voltage but have opposite polarity, brush fiber will shorten so, and the diameter of fiber will expand (broadening or bulging) in brief along with described change, convert electric energy to the mechanical energy of handling mascara brush.The interesting aspect of this application can be alternating voltage is applied to fiber, and it will cause described filament expansion and contraction, or with us, the frequency circulation of the voltage applying is increased and reduce hardness.This is the mode of piezoelectricity motive power work substantially, but we are just being applied to mascara brush fiber in this case.
Piezoelectric can have by its shape and size, determined through defining natural frequency.This frequency is the degree that material trends towards vibration naturally, and this frequency can be changed by electric current (voltage change vibration amplitude).Selective reaction material can comprise any one any crystalline material representing in 32 kind of crystalline.In these kind of crystalline 21 (how much point groups of crystallization) have direct piezoelectricity effect and by expressing possibility, are the composition persons for the material of the preferred types of this object.Described 21 kind of crystalline are 1,2, m, 222, mm2,4,4,422,4mm, 42m, 3,32,3m, 6,6,622,6mm, 62m, 23,43m and 432.
Being incorporated into selective reaction material in bristle, pointed tooth or other structure can be subject to continue electric field and maybe can form direct and contrary piezoelectricity and affect to form the pulsating field of oscillation effect in stiffness changing.
To be applicable to some of the recommendations selective reaction material of the present invention comprises:
Naturally-occurring material: bone, enamel, dentine, wood (piezoelectricity texture), silk, citrine, quartz, sucrose, berlinite, Rochelle salt, tourmaline family material;
Synthetic material: LGS (La3Ga5SiO14) and potassium orthophosphate (GaPO4) (both are synthetic quartz crystal);
Pottery: barium titanate (BaTiO3), lead titanates (PbTiO3), lead zirconate titanate (PbZrTiO3) (being called again PZT), potassium niobate (KNbO3), lithium niobate (LiNbO3), lithium tantalate (LiTaO3), sodium tungstate (Na2WO3), Ba2NaNb5O5, Pb2KNb5O15, potassium-sodium niobate (NaKNb), bismuth ferrite (BiFeO3), sodium niobate (NaNbO3);
Polymer: polyvinylidene fluoride (PVDF).
Existence is in order to handle several the possibility methods/configuration of applicator.For instance, can adjust by simple one pole or double-pole switch (turn-off/connect) or the multipole and/or multithrow switch with several different current settings the hardness/flexibility of brush.Or, can adjust by potentiometer or rheostat the hardness/flexibility of brush, or adjust with digital form by integrated circuit.Useful integrated circuit or other appropriate electronic control piece are handled hardness, comprise the pulse that causes hardness to be sent along with the energy of frequency shift, pattern or program.This pulse can have consistent frequency interval, can increase or reduce (gradually) along with the time, or be (cadent stress and/or the pause) of middle summary.This ripple frequency will not served as independent " vibration " (only flexibility changes), but when forming contact because of pointed tooth, tip or bristle contact eyelash, the effect of stiffness changing will be remarkable, and the movement of ciliary power realization in the flexibility of the dynamic change of mascara brush.Described change is proportional by the measurement of the electric dipole moment with material (tolerance of total polarization state of system).
Or hardness can change one by magnetic (electromagnetic field) and introduce magnetic field and/or make for a change flexible method of applicator of polarity inversion.
Can use battery, solar energy, kinetic energy (from the piezo-electric effect of the bending of the material by based on piezoelectricity, vibration, stirring etc.) or for example, supply power to applicator from other appropriate source connection of commercial power grid (to).
Cosmetics applicator forms the matrix of several different applicator surface conventionally, no matter it is pointed tooth, bristle, dish etc., and for these shapes, can in estimation range, select different material hardnesses.(ethnic group, gene, application are specific, as denseization or curling etc.) forms effective applicator in order specifically needing for more consumers, will require manufacturer to produce the flexible grade of many differences in applicator assembly.Provided more options level down low manufacture efficiency, and can to cause about what be that best consumer is puzzled for specific needs.The present invention is selecting to provide consumer flexibility aspect particular stiffness brush, limits the number of the version that manufacturer must produce simultaneously.This applicator allows user to handle the hardness of cosmetics applicator, and it is dynamic and mutual.User can select suitably to set and keep this to set, or depend on during a whole day in, for change needs of a plurality of application, life of product etc. and change setting.At manufacture view, only produce a version, because device can infinitely customize in consumer's hand.
