Description
The present invention relates to a kind of electric toothbrush, form by an one handle and a flexible head.The invention still further relates to this benefit that is used for the toothbrush of cleaning teeth.
Electric toothbrush is well-known in the present technique field, is typically to comprise an electrical machine element and a normally interchangeable brush that is installed in the brush holder.
A lot of electric toothbrushes by rapid movement brush (being referred to as swing toothbrush hereinafter) reach cleaning purpose, but other just by vibrate (being referred to as vibrating toothbruss hereinafter) reach cleaning purpose.
Many swing toothbrush are arranged on the market, and some have specific swinging structure, longitudinal oscillation element for example, and perhaps they have a plurality of brushes, and for example the trade mark sold of Phillips is " PlaqueRemover
" toothbrush, but it comprises and rotates brush and at the bristle in groups of the teeter of brush holder far-end.
The example of vibrating toothbruss is J ﹠amp; The trade mark that J sells is " Powerbrush
" toothbrush.
The manual toothbrush that has flexible brush head is also known in prior art.For example the trade mark of Unilever sale is " Adaptor
" toothbrush, it comprises a series of bunchy bristles that are fixed in the sheath.These sheaths are connected on the center framework by the rubber-like elastic body material.Like this, the bunchy bristle that is fixed in the sheath can be realized the motion of toggle formula when brushing teeth.
The shortcoming of swing toothbrush is that the electric toothbrush that requirement reaches the purpose of correctly brushing teeth comprises expensive technology.The common low price point of vibrating toothbruss, its shortcoming are that they must vibrate the benefit that realizes any type cleaning quite greatly.Because brush holder is vibrate the same with brush usually, this vibration usually allows the user feel under the weather.In addition, the user is not clear is that toothbrush is used as the vibration manual toothbrush or is used as the electric toothbrush use.
An object of the present invention is to provide a kind of cheap electric toothbrush, it can provide the benefit of improving cleaning effect, and use easy, comfortable.
When we found that brush is flexibility, electric toothbrush can be made improvement to prior art.
Therefore, the invention provides a kind of electric toothbrush of forming by handle and head, it is characterized in that its head is flexible.
Obviously, the head of electric toothbrush is formed by the bristle support with the neck that the bristle support is connected on the handle.
In a certain embodiments, its head be cut apart to produce pliability.Though on this brush of cutting apart any a plurality of part can be arranged, each part and any a plurality of other parts can be one, or are connected in any a plurality of other parts by other material.
In another embodiment, its head comprises rubber-like material.This rubber-like material can connect the each several part of the brush of cutting apart.
The inclusion of flexible head can be improved the vibration characteristics of brush in such a way, promptly compares the effect that has not been to improve cleaning with swing toothbrush, has improved the action of vibrating toothbruss exactly.Also the inclusion of possible flexible head reduces the output quantity that electrical machine element is required, and it is more comfortable that this can make toothbrush use again, and reduced the power requirement, thereby reduced the battery altering frequency.
A key character of the present invention is that brush is flexible.Traditional brush comprises hard material, for example polypropylene and polyacrylonitrile, and it can be provided the flexibility of head by the physical size of these materials, and for example this brush comprises two or more parts, and they are by being connected with each several part all-in-one-piece hinge.
Yet foreseeable is that this brush also comprises rubber-like material to produce flexibility.
Also might almost completely form by this brush by rubber-like material, the material that more traditional employing is harder, for example polypropylene or styrene-acrylonitrile are used for fixedly providing convenience to the bunchy bristle.
In a special preferred embodiment, rubber-like material extends to the sizable part that covers the brush neck.Because rubber has cushioned the vibration of motor, rely on this class rubber can reduce the incidence of injury user's gums and lip.
Rubber-like refers to material and has some elastic characteristics.Suppose that electric toothbrush vibrates with extremely high frequency, can expect that high-elastic characteristic is unnecessary, the little material of Xiao A hardness of the polypropylene material that uses than tradition is suitable for using in the present invention.
In a preferred embodiment, the Xiao A hardness of rubber-like material is more preferably less than 80 less than 100, preferably less than 55.
Specially suitable rubber-like material comprises airframe material, those that in WO97/20484, describe for example, and its content is hereby incorporated by.
In another embodiment, can obtain the flexibility of head by the hinge of use between bristle support and neck.
This brush can comprise arbitrarily, and a plurality of this hinges provide flexible.Be typically, this hinge will be located such that deflection effect maximization in use.Thereby they will be preferably placed at the bristle support of head.Hinge can be positioned at the optional position of the bristle support of this head.For example it can cross total longitudinal axis of head, by being provided with at an arbitrary position, the length of for example pressing the bristle support towards the top half or 60%, or towards 30% place on top, between the top of the bristle support of head and bottom, head part is become two parts.
Can imagine that brush according to the present invention is interchangeable.
In another form, the invention provides a kind of electric toothbrush that improves sensation that is of value to.Toothbrush according to the present invention provides the improvement of feeling in the oral cavity, particularly toothbrush when head or neck comprise rubber-like material.It is especially true when the area supported without bristles of head is coated with rubber-like material basically and contacts with the cheek internal layer.It is an important benefit that this sensorial benefit is regarded as the user.
Therefore, the present invention also provides the benefit of the electric toothbrush that comprises handle and head, and this head includes to benefit and improves the rubber-like material of feeling in the oral cavity.
Electric toothbrush according to the present invention provides improvement by the inclusion of flexible head to prior art.Well imagine that flexible head is because its flexible characteristic, or or rather owing to constitute swing/vibrations that the elasticity difference of the material/part of head has produced enhancing.
