Description

Device for cleaning teeth

The present invention relates to a kind of device for cleaning teeth.

Dentists suggest that people are cleaning teeth often, all clean tooth after preferably every meal.

For this reason, before once suggestion provided toothbrush, generally need a certain amount of water and pond or basin but brush teeth with toothbrush.

Also once suggestion utilizes the supplementary means of chew gum as cleaning teeth.This is favourable really aspect not water and pond, but chew gum does not reach good effect for one group of tooth of cleaning, especially when tooth is stained with chewing gum.

The present invention makes every effort to provide a kind of device for cleaning teeth of improvement.

According to the invention provides a kind of device for cleaning teeth, this cleaner comprises a flexible member, and this flexible member is suitable for the distortion from the original state to the end-state, this flexible member, in its original state, many bristle and many straight down bristles straight up are housed.

Preferred this flexible member limits and forms four outer surfaces, and these four outer surfaces are equipped with described bristle.

Preferred this flexible member is a lozenge shape cross-section, and the upper surface that it has two inclinations is being supported the bristle that makes progress, and the lower surface of two inclinations is being supported downward bristle.

Be that these four outer surfaces are made of four flat boards easily, these four flat boards are connected to each other and form in a tubular form a core of above-mentioned cleaner substantially.This tubular portion is an elastically deformable.

On the other hand, this flexible member is a kind of elastic foam material.

The length of its bristle that advantageously will upwards stand and the downward bristle that erects is chosen to make the top of bristle, forms a groove on the top of flexible member, and forms an inverted groove in the bottom of flexible member.

The length of preferred this cleaner is substantially equal to the width of a tooth.

Perhaps, the length of this device is equivalent to the width of at least two teeth basically.

Be that above-mentioned bristle is provided with a kind of medium of tooth only easily.

Advantageously above-described device can be fixed on the handle.

In order to be easier to understand the present invention, thereby and be appreciated that its other feature, next we will describe this invention with reference to accompanying drawing by example, wherein:

Fig. 1 is the perspective view according to the flexible member of the part of this device for cleaning teeth of formation of the present invention.

Fig. 2 is the perspective view according to device for cleaning teeth of the present invention.

Fig. 3 is about the schematic diagram of device for cleaning teeth among Fig. 2 when planning to use, and two relative teeth schematically are shown among the figure.

Fig. 4 is the view corresponding to Fig. 3, and the situation when two teeth shift near a little mutually is shown.

Fig. 5 is the view corresponding to Fig. 4, and the position when two teeth shift near fully in opposite directions is shown.

Fig. 6 illustrates tooth and loosens the also view of separated position.

At first, with the frame form flexible member is shown among the figure with reference to Fig. 1 of accompanying drawing.Its framework is a tubulose, and the cross section of pipe is rhombus basically.Therefore, can think that framework 1 is by four interconnective panels 2,3,4,5 compositions.Each panel couples together by the panel of hinge or broken line and vicinity, such as is in the broken line 6 between panel 2 and the panel 5.These four panels are represented four surfaces outwardly.Central frame 1 can be made up of for example stretchy nylon material.This central frame has an initial conditions as shown in Figure 1, and this framework is suitable for vertically being pushed, and as shown in fig. 1, this point will be more clear in the following description.

Refer now to Fig. 2, device for cleaning teeth 10 comprises the framework 1 that discloses previously.What be fixed in framework 1 outer surface is many bristles 11, and bristle 11 lays respectively at panel 2,3, and on 4,5 outer surfaces that limit, four panels constitute framework 1 jointly.

Bristle is not to extend perpendicular to the surface of supporting them.Bristle is oriented like this, promptly as shown in Figure 2, when device 10 is in its initial " not stressing " state, two upper surfaces that limited by panel 2,5 favour horizontal direction with about 45, two lower surfaces that limited by panel 3,4 then favour horizontal direction with about 45, bristle 11 extends straight down from panel 3,4 then substantially from panel 2,5 straight up.So, about and its seating surface extension at 45 of bristle.

The bristle that stretches upwards comprise the long bristle that is positioned at contiguous panel 2 and panel 3 junctions and be in contiguous panel 4 and 5 junctions than long brush hairs.Bristle also comprises the relative bristle of lacking some of contiguous panel 2 and panel 5 junctions.

The whole setting is such: the groove 12 of the common formation of upper end that is in upper panel 2 and the bristle above the panel 5, as shown in Figure 2, when said apparatus was in " not stressing " state, this groove had a

side

15,16 of flat bottom surface 14 and two inclinations basically.This device is symmetrical in a horizontal line, and therefore, the long bristle with short that comprises that is on panel 3 and 4 also forms one " groove " jointly, and promptly inverted groove 17.

According to our imagination, bristle 11 will be than the bristle thinner (being that diameter is less) of the ordinary toothbrush of our usual usefulness and more more.

It is envisaged that, this bristle is coated a kind of medium of feeling comfortable cleaning teeth with a kind of form of auxiliary clean tooth material, it can apply with humidity or dry form, after being produced when device shown in Figure 2, above we arrive this surge.This material can be equivalent to the effect of toothpaste.

Refer now to Fig. 3 to Fig. 6, device 10 state just in use shown in each figure among Fig. 2.Starting apparatus 10 is between selected upper teeth 20 and the selected lower teeth 21.In use, utilize tongue to fiddle with this device, be in the groove 14 that the top of device shown in Figure 2 10 forms up to upper tooth 20, and till lower tooth 21 is in the groove 17 that the bottom of device 10 forms.Upper tooth 20 and lower tooth 21 move towards each other then, as shown in Figure 4.These two tooth contacts form the bristle of groove 14 and groove 17 bottoms, and begin to push central frame, so central frame trends towards " rhombus ".Panel 2 and 5 trend towards horizontal level with downward motion, and panel 3 and 4 then trends towards horizontal level with the motion that makes progress similarly.The motion of this panel can make the bristle that moves up and down in parallel substantially mode at first move to a kind of state of bristle polymerization.The bristle that forms the

side

15,16 of groove 14 thus will contact with tooth 20, also can reach similar effect for tooth 21 simultaneously.Ensuing pressure is drawing tooth 20 and thereby tooth 21 slides with respect to exterior of teeth near the long bristle that makes the

side

15,16 that forms groove 14 mutually, shifts to gums 22.Like this, bristle is a upper tooth 20, and the effect of cleaning also is provided for lower tooth 21 certainly.Loosen tooth then, move away from each other, so because with the elasticity of the flexible member 1 of the framework of four panels formation, this device is in position shown in Figure 6, yes in this position same as shown in Figure 3 position.Two teeth can move on to the repetition cleaning effect of coming together once more, and perhaps this device can move along tooth, run into a time-out with two teeth of box lunch, can clean a pair of relative tooth in addition.

Fig. 3 can be equivalent to the width of a typical tooth to the device length of Fig. 6.Yet, arrive shown in Figure 10 as Fig. 7, according to device of the present invention long length can be arranged also, so according to device 30 of the present invention, it has identical as mentioned above structure basically, can adopt long length, it is long enough to contact at least two teeth 31 simultaneously in one group of tooth in the above, 32, and contact at least two

teeth

33,34 simultaneously in one group of tooth below, as in Fig. 7, seeing, in position shown in the figure of this device, at least also contacted with 34 dental part at contiguous selected

tooth

31,32,33 by this device.In Fig. 7 and Fig. 8, this device is in initial position, and its central frame is in wide-open position, and in Fig. 9 and Figure 10, this device is in another kind of position, promptly is in the position that each tooth pushes in opposite directions.

In another embodiment, flexible member 1 is to be made of a kind of elastic foam material, and such as foamed plastics, it has the cross section of rhombus.

The device 10 that Figure 11 illustrates as shown in Figure 2 is fixed on the handle 40, so this device just can use by the mode of traditional toothbrush.It is pointed out that handle links to each other with a panel 4 of the central frame of device 10, makes device 10 operate in above-described mode like this.
