Description

A kind of novel toothbrush head

Technical field

The present invention relates to the basic area of toothbrush.More specifically, the invention provides that rotation brushing that a kind of more modern dental medicine that proposes according to the present invention advocates has more the improvement rotation brushing of operability and the brand-new head toothbrushes bristles rod structure that designs.Utilize current toothbrushes production technology, bristles material and toothbrush handle construction, in conjunction with novel toothbrush head bristles rod structure of the present invention, can produce a new generation, have guiding toothbrushing person study and grasp improvement rotation brushing function of the present invention, can clean all dental surfaces more easily, all sidedly and efficiently and gum be had the tooth brush for health protection of good massage effect.

Technical background

As everyone knows, the effect of toothbrush is teeth surfaces and then caries prevention and relevant mouth disease.Manual toothbrush is made up of head toothbrushes and toothbrush handle.Head toothbrushes then bunch is made up of the bristles post on a passive Toothbrush board and its.The bristles post of traditional toothbrush bunch size is consistent, highly neat, is arranged in regularly on the Toothbrush board face usually.Every group of bristles post one end embeds the Toothbrush board face, and the other end has then formed the toothbrush working end of cleaning action.

The tradition brushing relates generally to the cleaning of tooth cheek side surface.It requires toothbrushing person to contact dental surface to be cleaned and finish cleaning course along the mobile toothbrush of teeth space direction (upwards to the Lower Half tooth, downwards to first half tooth) with front, toothbrush working end (being that the bristles post is in its warp and the vertical state of dental surface to be cleaned).

When stating traditional toothbrush by traditional brushing cleaning teeth in the use, uniform bristles post working end can only effectively contact the dental surface that is the plane relatively, so its cleaning effect is very limited.Because the restriction of oral cavity space, traditional brushing is difficult to cleaning teeth tongue side surface.

At above-mentioned defective, people have proposed numerous corrective measures.These measures can be divided into three major types.

The first kind: continue to use traditional brushing, set about from improving bristles rod structure itself, people have proposed a lot of corrective measures is difficult to contact dental surface recess to be cleaned with improvement hair post bunch uniform height and the bristles post working end that regular arrangement causes shortcoming.These measures also are that relevant toothbrush head hair column structure invention relates to maximum fields.These inventions are most around how improving bristles post Zheng Ding working end shape and the hair post is arranged, thereby expecting that these improved toothbrush working ends can coincide with the dental surface profile better can clean the dental surface recess that traditional toothbrush can't clean.For example, to recessed surface, molar hat top, the invention that has is designed to a conical surface to the working end of toothbrush head bristles post group and than all the other bristles post group leaders, has improved the cleaning to recessed surface, molar hat top.But all the other surfaces to be cleaned for tooth, at first, the thinking of this class corrective measure is based on traditional vertical cleaning teeth brushing, so even these corrective measures can improve bristles post Zheng Ding working end to the dental surface profile coincide but they can't surmount this tradition brushing intrinsic shortcoming.In fact, such its effect of improvement is very limited.Because the outer table skeleton of tooth because of tooth and in the oral cavity relative position different, so in the process of brushing teeth of reality, this static state identical can not make bristles post working end always keep suitable contact the with institute's teeth surfaces veritably.Moreover, these corrective measures also have one very their a hair rod structure of imperfection part one misguide the consumer easily and continue to use incomplete traditional brushing, stoped the extensive use of the rotation brushing that modern dental medicine advocates.Consequently the consumer of considerable part has damaged their gum and tooth because of teeth brushing way improperly, particularly desires to clean its tooth more up hill and dale and when firmly brushing teeth at toothbrushing person.

Second class: from cleaning and the massage that improves gum, have invention to propose to be provided with flare, than the measure of the longer bristles post of other bristles post bunch in the head toothbrushes both sides.But still continue to use traditional brushing, wish that in other bristles post bunch cleaning teeth this special bristles post bunch can clean and massage gum.So the material of this bristles post bunch must can not be common bristles post material for the material such as the rubber of particularly soft.

The 3rd class: from method for brushing teeth, bristles post working end should be 45 degree with dental surface to be cleaned when modern dental medicine had proposed to brush teeth, thereby then along the rotation brushing of teeth space direction rotary toothbrush teeth surfaces.But toothbrushing person is difficult for grasping this skill of brushing teeth.Invention (US005305489) has therefore designed with the Toothbrush board face and has been the toothbrush handle of 45 degree to overcome above-mentioned shortcoming.This rotation brushing has improved three big shortcomings of traditional brushing along the vertical teeth surfaces of teeth space direction: one, when with the positive contact in bristles post working end tooth, bristles post working end is difficult to contact the recessed surface (as the close gum place of tooth two bottom sides) of tooth to be cleaned; Two, gum may be injured particularly when toothbrushing person is firmly brushed teeth in the course of the work in harder bristles post Zheng Ding working end; Three, in the cleaning course of reality, to such an extent as to thereby part bristles post can crooked its working end move along the dental surface that is cleaned and lost due cleaning capacity.But use this rotation brushing when cleaning teeth tongue side surface tongue side surface especially at the cleaning front tooth, not easy to operate.At the bristles post clustering architecture deallocation that uses traditional toothbrush should also have two big weakness during the rotation brushing: 1, to such an extent as to although this rotation brushing can make the lateral parts of its working end of bristles post distortion can go deep into dental surface recess to be cleaned, the strength that is difficult to provide enough goes removing to adhere to these lip-deep dirts; 2, be the line contact with the bristles post working end that dental surface effectively contacts, fail to make full use of the cleaning potential of toothbrush working end.

In sum, more than improve and fail comprehensively to examine the interaction and the restriction of tooth structure, brushing and bristles rod structure, many To be improved parts are still arranged.Given this, the present invention should be with the design philosophy of different bristles post bunch cleanings in line with the different dental surface, tooth is classified according to difformity and position, characteristics at all kinds of teeth have designed corresponding brand-new bristles post bunch shape again, in conjunction with the improved rotation brushing that has more operability, thereby make the process dens in dente brush column working end of the brushing teeth dental surface profile that to coincide effectively, reach the effect of cleaning teeth, massage gum.

Summary of the invention

At first, the present invention will be distributed in the size of restricted oral cavity space, the dental surface that shape differs is divided into four big classes: 1: recessed surface, molar hat top, 2: the tongue side surface of front tooth, 3: tooth cheek side surface, 4: the tongue side surface of all the other teeth except that front tooth; Then, according to the dental surface feature of above-mentioned four big classes, the present invention has at first designed corresponding improved rotation brushing; At last, invented corresponding bristles post bunch shape and reasonable Arrangement again and constituted a kind of brand-new head toothbrushes at the Toothbrush board face.Head toothbrushes of the present invention is made up of four molar brush column groups, and this four molars brush column group is responsible for cleaning corresponding above-mentioned different dental surface:

One. one group of molar hat recessed surface, top and between cog teeth space space that is mainly used in the cleaning first kind is positioned at head toothbrushes bristles post group foremost.This bristles post group is made up of at least two bunches of bristles posts that are symmetrical in toothbrush center warp, and its height is than other bristles post group leader, and its middle part, surface, working end protrudes the mountain peak shape.When recessed surface, cleaning molar hat top, this improved rotation brushing requires toothbrushing person to keep flat toothbrush, and (the toothbrush working end is up to first half tooth, or down to the Lower Half tooth) make the corresponding recessed surface, molar hat top of toothbrush operative end surface contact, move horizontally toothbrush before and after the whole secondary tooth gear profile in edge then and finish cleaning course.

Two. the tongue side surface of two groups of all the other teeth except that front tooth that are mainly used in cleaning tooth cheek side surface of the 3rd class and the 4th class and the cleaning and the massage of gum, be positioned at head toothbrushes two outsides, be symmetrical in the bristles post group that toothbrush center warp and bristles post working end tilt to two outsides.Every group of bristles post is made up of some bunches bristles post, arranges and is formed up to rare cluster along the toothbrush warp direction, but two bunches of bristles post working ends are arranged than the bristles post group of all the other bristles post working ends further from toothbrush center warp at most.When these dental surfaces of cleaning, this improved rotation brushing and existing rotation brushing basically identical, just this improved rotation brushing does not impose toothbrushing person must keep toothbrush to become any special angle with dental surface to be cleaned, so long as not getting final product with front, bristles post group working end (bristles post warp is vertical with dental surface to be cleaned) teeth surfaces.In fact, this improved rotation brushing advocates that toothbrushing person is approximate to keep flat toothbrush (the toothbrush working end is up to first half tooth, or down to the Lower Half tooth) make this bristles post group working end (inclination part) contact cover the gingival surface of teeth roots to be cleaned, folk prescription is to making progress to the mobile head toothbrushes of Lower Half tooth (or downwards to first half tooth) along the teeth space direction then, or make this bristles post group working end streak corresponding gingival surface successively along Toothbrush board short-axis direction rotary tooth brush, tooth to be cleaned bottom connects the gum place, tooth tooth body to be cleaned surface, the part dental surface of the corona of tooth to be cleaned and finish cleaning course.In cleaning, during the massage gum, this improved rotation brushing suggestion toothbrushing person is approximate to keep flat toothbrush (the toothbrush working end is up to first half tooth, or down to the Lower Half tooth) make this bristles post group working end (inclination part) contact gingival surface to be cleaned, make this bristles post group working end promptly finish the cleaning of gum, massage process with the horizontal brushing that draws then in gingival surface move left and right to be cleaned.

Three. one group of tongue side surface that is mainly used in the cleaning front tooth is positioned at head toothbrushes end and the bristles post working end bristles post group to the hypsokinesis of toothbrush handle direction.This bristles post group bunch is made up of two bunches of bristles posts that are symmetrical in toothbrush center warp.During cleaning, brushing of the present invention requires toothbrushing person to keep flat toothbrush (the toothbrush working end is down to the Lower Half front tooth with approximate, or up to first half front tooth) make this bristles post group working end (hypsokinesis part) contact cover the gingival surface of front tooth root to be cleaned, first half front tooth (or forward upwards to Lower Half front tooth) folk prescription is finished cleaning course to pulling out toothbrush downwards forward then.In cleaning course, toothbrushing person can gently shut up lip in case the toothpaste foam spill.In fact, if can cleaning more this toothbrushing person of polydonita radula side surface by this method, toothbrushing person thinks that this method is easier.

Four. some ordinary toothbrush hair posts bunch that intersperse among between the above-mentioned bristles post group hair post bunch.It mainly acts on has been dispensing toothpaste and general cleaning action.

It is to be noted, adopt the toothbrush of bristles rod structure of the present invention production that three big benefits are arranged: at first, shape and the position clear and definite above-mentioned three groups of special bristles post groups of the division of labor will guide toothbrushing person clearly and easily to understand and grasp short and sweet improved rotation brushing of the present invention.Secondly, above-mentioned three groups of special bristles post groups are when the corresponding dental surface of cleaning, thereby its surface, working end can be made corresponding deformation with dental surface profile varying to be cleaned and makes it can closely contact these dental surfaces; Moreover, these rubber-like working ends can also remain this contact condition and produce enough cleaning power in whole cleaning course; Therefore, the toothbrush that adopts bristles rod structure of the present invention to produce, with more convenient, clean all dental surfaces comprehensively, efficiently.The 3rd, the whippy bristles post group that is positioned at the head toothbrushes both sides can also draw brushing directly to clean and the massage gum with horizontal.

In sum, the toothbrush that uses bristles column cap of the present invention to produce, and by improved rotation method for brushing teeth cleaning teeth of the present invention, with more convenient, clean all dental surfaces comprehensively, efficiently, comprise corona, cheek side dental surface, tongue side dental surface even between cog teeth space space, and gum is had good massage effect.

In conjunction with reference to being all the description of the accompanying drawing of a part of the present invention, we can be illustrated more clearly in improved rotation brushing and the toothbrush head hair column structure of the present invention that operability is more arranged of the present invention, understand its distinct advantages.

Description of drawings

With reference to figure 1, head toothbrushes (10) has peculiar toothbrush head hair column structure feature of the present invention (12).Head toothbrushes (10) is the part (toothbrush handles is not shown among the figure) of typical toothbrushes.Be applied to electric toothbrush as head toothbrushes of the present invention (10), then evaporation cham must comprise the suitable electric transmission machanism of a cover.

Although head toothbrushes (10) is shown as common Toothbrush board (14) (16) in the drawings, this is construed as head toothbrushes (10) can have other shape and not depart from the scope of the present invention.

As ordinary toothbrush, the hairbrush cylinder of head toothbrushes (10) is made up of single bristles (18).Every bristle passes (18) has the hair post bottom (20) and the hair capital end (working end) (22) away from Toothbrush board (14) that are fixed on the Toothbrush board (14).

Cluster tuft brush cylinder is arranged to constitute F-SP to increase the cleaning capacity of head toothbrushes.For the position of these hairbrush cylinders being described better, head toothbrushes (a 10) definition major axis (along the direction of toothbrush warp) (24) and a minor axis (along direction) (26) perpendicular to the toothbrush warp; A head toothbrushes end (28) (joining with toothbrush handle, not shown) and a head toothbrushes front end (30).

The present invention has designed the hairbrush cylinder of three groups of uniquenesses:

First group of hairbrush cylinder (32) comprises that two bunches or more bunches are positioned at head toothbrushes front end (30), are symmetrical in the hairbrush post bunch (34) of major axis (24).

This hairbrush post bunch (34) is usually than all the other hairbrush cylinders, as is positioned at the long 2～3MM of common hairbrush post bunch (86) at center.Certainly, this outstanding height may change and not depart from the scope of the present invention.

In addition, the operative end surface (36) of this hairbrush post bunch (34) is an inclined plane.This inclined surface (36) is tilted to down along the direction away from major axis (24) in minor axis (26) direction.

As shown in Figure 7, this hairbrush post bunch (34) has defined a major axis (38) that becomes inclination angle (40) with axis of reference (42) (vertical extend out from Toothbrush board (14)).This angle (40) is generally 5～15 degree.Although do not get rid of other angle, the inclination angle (44) of operative end surface (36) generally becomes 45 degree.It should be noted that shown angle is a model herein, real angle and feature can change to some extent and not depart from the scope of the present invention.

As shown in Figure 8, the inclination operative end surface (36) of hairbrush post bunch (34) can contact recessed surface (46), molar hat top well.In addition, this hairbrush group (32) also can be used for cleaning the common hairbrush post of two between cog and bunch is difficult to deep teeth space space.

Hairbrush post bunch (34) is when cleaning molar hat recessed surface, top (46), and the operative end surface of its inclination (36) at first provides the possibility on recessed surface, extensive contact molar hat top; Simultaneously, the shaft of the hairbrush post of its inclination bunch (34) can also provide an extra ability to make its operative end surface (36) more up hill and dale, fully contact recessed surface (46), molar hat top by distortion.

When the brush plate face (14) of horizontal positioned drove hairbrush group (32) on it and moves forward and backward along whole secondary tooth profile level, the operative end surface (36) of hairbrush post bunch (34) can be finished the cleaning course on recessed surface, single group molar hat top.At different tooth positions, repeat the cleaning that this cleaning course is promptly finished recessed surface, whole molar hat top.

Second group special bristles post group comprises that two groups are symmetrical in major axis (24), is positioned at Toothbrush board face (14) two outsides, near the hairbrush cylinder (50) of Toothbrush board side surface (52).Every group of hairbrush cylinder (50) by cluster or two tufts brush post bunch (54 ') and two or more tufts brush post bunch (54) and form and arrange along major axis (24) direction.The working end (22) of hairbrush post bunch (54) or hairbrush post bunch (54 ') all tilts in the direction of minor axis (26) direction to Toothbrush board side surface (52).In Fig. 7, hairbrush post bunch (54) has defined one and has become major axis (56) the hairbrush post bunch (54 ') of angle (58) then to define a major axis (56 ') that becomes angle (58 ') with axis of reference (42) with axis of reference (42).This angle (58) or (58 ') are generally 10～20 degree.In addition, must to form the floor projection line of its operative end surface (64) be protruding or recessed outer contour (60) to the layout of hairbrush post bunch (54) (54 ').As shown in Figure 6, the hairbrush post bunch (54) that the hairbrush post of more close Toothbrush board side surface (52) bunch (54 ') is more adjacent thus the more outward-dipping floor projection outline line (60) that forms a convex.Certainly, also can be as shown in Figure 3, the hairbrush post bunch (54) that the hairbrush post of two bunches of bigger and more close Toothbrush board side surfaces (52) bunch (54 ') is more adjacent thus the more outward-dipping floor projection outline line (60) that forms a concavity.

Moreover, the working end (22) of hairbrush post bunch (54) (54 ') generally is the operative end surface (64) (64 ') on a non-straight plane.This operative end surface (64) (64 ') can be a multiple shape and not departing from the scope of the present invention.For example, this operative end surface can be as Fig. 1, shown in 3, is a simple surface; Also can be as Fig. 2, shown in 4, be a curve and straight top planar combination; Also can be tiltedly straight plane.

In addition, the horizontal profile projection line solstics of the operative end surface (64 ') of hairbrush post bunch (54 ') may be because of the length and different variation the in its inclination angle (58 ') of head toothbrushes width, hairbrush post bunch (54 ') to the distance (68) of Toothbrush board side surface (52).Therefore the operative end surface (64 ') of hairbrush post bunch (54 ') also may flush and not depart from the scope of the present invention with Toothbrush board side surface (52).

Figure 10 and Figure 11 have described tooth cheek side or the tongue side surface (70) (72) that how to use second group of hairbrush cylinder (50) to remove cleaning teeth (48).When using second group of hairbrush cylinder (50) cleaning teeth cheek side (70) or tongue side surface (72), hairbrush post bunch (54 ') mainly is responsible for cleaning between cog teeth space space and adjacent teeth surface (62), meanwhile, hairbrush post bunch (54) then is responsible for the corresponding tooth cheek side (70) or the tongue side surface (72) on cleaning next door.When cleaning, at first, approximate keep flat toothbrush and make the operative end surface (64) (64 ') of this hairbrush cylinder (50) be close to the gingival surface (90) of tray covered teeth root--with reference to Figure 10, and the corresponding teeth space space of desiring cleaning teeth of hairbrush post bunch (54 ')-with reference to Figure 11; Then, move up toothbrush to Lower Half tooth (or moving down first half tooth) along axis (42), or make the operative end surface (64) (64 ') of second group of hairbrush cylinder (50) streak gingival surface (90) successively at minor axis (24) direction rotary tooth brush head (10), dental surface (70 or 72) and corona side surface and finish the cheek side (70) of this tooth or the cleaning course of tongue side surface (72).Repeat this cleaning course, finish the cleaning of the tongue side surface of the cheek side of whole teeth and all the other teeth except that front tooth.Because everyone tooth is not of uniform size, so when actual brushing teeth, toothbrushing person can be according to its concrete condition flexibly in conjunction with above-mentioned perpendicular brush and rotation method for brushing teeth.

Because the hairbrush post bunch (54) (54 ') of this group hairbrush cylinder (50) can produce corresponding deformation with the appearance of institute's cleaning teeth in cleaning course, its operative end surface (64) (64 ') can keep well contacting with institute's cleaning teeth outer surface.Moreover, have special hairbrush post bunch (54) (the 54 ') structure that strengthens its operative end surface (64) (64 ') elastic force function and guaranteed the clean enough power of its operative end surface (64) (64 ').In addition, because toothbrush head hair column structure of the present invention (12) is designed to once only clean one or two adjacent teeth, the cheek side or the tongue side dental surface of institute's desire cleaning can be located and clean to toothbrushing person easily exactly, and the guiding toothbrushing person conscientiously cleans each tooth.

Head toothbrushes of the present invention (10) also comprises the 3rd group hairbrush cylinder (74).This group hairbrush cylinder (74) is positioned at the tail end of head toothbrushes near head toothbrushes end (28), generally comprises the hairbrush post bunch (76) that minimum cluster is generally two bunches.The working end (22) of this hairbrush post bunch (76) tilts to head toothbrushes end (28) along major axis (24) direction.

As shown in Figure 5, the major axis (78) of one of hairbrush post bunch (76) definition and axis of reference (42) formation angle (80).This angle (80) is generally 15～30 degree.The operative end surface (82) of this hairbrush post bunch (76) is similar to the operative end surface (64) of second group hairbrush cylinder (50).This operative end surface (82) is mainly used in the tongue side surface (88) of cleaning front tooth.When cleaning, as shown in Figure 9, level of approximation is placed operative end surface (82) the contact front tooth tongue side surface (88) that Toothbrush board face (14) makes hairbrush post bunch (76), first half front tooth (or forward upwards to Lower Half front tooth) folk prescription is finished cleaning course to mobile toothbrush downwards forward then.Repeat this cleaning course until the cleaning of finishing whole front tooth tongue side surfaces.

Be the elastic force of the operative end surface (82) of the hairbrush cylinder (74) of the operative end surface (64) (64 ') that strengthens second group of hairbrush cylinder (50) and the 3rd group, the present invention has designed the special hairbrush cylinder (54) (54 ') (76) of several shapes especially.In Fig. 1, special hairbrush cylinder (54) (54 ') (76) is its major axis (56) (56 ') (78) direction stepped (lower section is big than its cross section, top).This structure not only helps strengthening the elastic force of its operative end surface (64) (64 ') (82), and is very beneficial for manufacturing of these special hairbrush post bunch (54) (54 ') (76); At Fig. 2, in 3,4, the cross section absolute value of special hairbrush cylinder (54) (54 ') (76) is big than special hairbrush cylinder (54) (54 ') (76) among Fig. 1 and cross section special hairbrush cylinder (54 ') is big than the cross section of its contiguous special hairbrush cylinder (54); In addition, the corresponding inclination angle (58) (58 ') (80) of special hairbrush cylinder (54) (54 ') (76) can be identical also can be different.

For limiting the deformation range of second group and the 3rd group hairbrush cylinder, go up even can set up a section at the Toothbrush board face (14) that is generally flat face and be down trapezoidal Toothbrush board face platform, have enough cleaning power to guarantee second group and the 3rd group of hairbrush cylinder cleaning face (64) (64 ') (82).

Normally, second group of hairbrush cylinder (50), the vertical height (92) of hair post bunch (54) (54 ') (76) (86) of the 3rd group of hairbrush cylinder (74) and the 4th group of hairbrush cylinder (84) is generally identical, and low than first group of hairbrush cylinder (32).But the vertical height of the hair post bunch (76) of the 3rd group of hairbrush cylinder (74) also can a little higher than the 4th group of hairbrush cylinder (84) hair post bunch (86) and do not depart from the scope of the present invention.

In addition, being positioned at the diameter of the common hairbrush post bunch (86) at Toothbrush board (14) center can be different and can flexible arrangement: between both can having interspersed among second group of hairbrush cylinder (50) of two groups along central shaft (24); Also can be positioned among second group of hairbrush cylinder (50); Also may be interspersed between second group and the 3rd group of hairbrush cylinder and do not depart from the scope of the present invention.
