Abstract

A tongue cleaner (10) has an elongate shank portion (16) for holding thereof, and a portion (20) extending from one end thereof for supporting a tongue scraping edge (22). The support portion (20) is skewed relative to the shank portion (16) to slope downwardly for effecting engagement of the edge (22) with a posterior part of the upper surface of the tongue (12), so that the posterior part may be comfortably scraped.

Description

Tongue cleaner

The present invention relates generally to a kind of tongue cleaner,, is used for object that the upper surface of a people tongue is swiped that is.

At the United States Patent (USP) D221 that authorizes as one of the present patent application people's Dasan Potti, can find the example of some tongue cleaners in 036 and D338,084.At an end of shank, there is a part outwards to open so that with the end of tongue scraping edge bearing at tongue cleaner.Described edge on the tongue upper surface from after move forward about 2 to 3 times so that swipe described upper surface reliably.Carry out a kind of like this tongue scale removal operation after finishing and taste bud " is revived " and alleviate halitosis brushing teeth.By bacillus of removing growth and the corrosion food particle that causes plaque, can reduce the corrosion and the gum disease (gun disease) (gingivitis) of tooth dramatically with the tongue scale removal of using a kind of like this device to carry out.Different with toothbrush, this tongue cleaner device needs lightly and smoothly tongue to be carried out scale removal.

People wish and can swipe to the entire upper surface of tongue.Though the tongue cleaner in the above-mentioned patent can touch the front portion of tongue easily,, the tongue rear portion is extended downwards or is tilted, so tongue cleaner just can not touch this rear portion equally easily.Therefore, may require user tilt comfortlessly described shank until mouthful root, so, a lot of people just may be reluctant tongue has been carried out scale removal.

Therefore, one object of the present invention is to provide a kind of tongue cleaner, and it can carry out scale removal to the whole tongue that comprises the rear portion more easily.

In order to make people can touch the tongue rear portion easily so that it is carried out scale removal, according to the present invention, a kind of tongue cleaner is provided, it supports the marginal portion of the tongue that is used for swiping, described tongue cleaner is crooked so that downward-sloping with respect to shank, follow the downward slope at tongue rear portion closely,, and can not make user comfortlessly towards the root of the mouth described shank that tilts so that described edge contacts effectively with the tongue rear portion.

Above and other objects of the present invention, feature and advantage will become more clear from the specific descriptions of preferred embodiment of the present invention being done below in conjunction with accompanying drawing, in each accompanying drawing, every identical label is all represented identical or similar parts.

Brief Description Of Drawings

Fig. 1 is a vertical view of implementing a tongue cleaner of the present invention.

Fig. 2 is its upward view.

Fig. 3 is its side view, a swiping people's the rear portion of tongue of shown tongue cleaner, and the opposite side of this tongue cleaner is identical with this side.

Fig. 4 is the view of one end.

Fig. 5 is the view of its other end.

Fig. 6 is an axonometric chart, is used for illustrating its operating position in the process of tongue being carried out scale removal.

The specific descriptions of preferred embodiment

Now see also each accompanying drawing, among the figure with label 10 total show an object integral type, thin, it is made by molded plastics or other suitable material, is used for a people's 14 tongue 12 is carried out scale removal.Tongue cleaner 10 comprises an elongated shank 16, so that tongue cleaner is held in the hands 18 of user so that tongue is carried out scale removal, this will be described hereinafter.There is a part 20 to extend out, and outwards opens, an edge part 22 is bearing in an end place of described tongue cleaner from this from an end of shank 16.Therefore, each side of supporting part 20 all stretches out from each side of described shank 16, thereby makes among the figure width of width shown in 48, supporting part 20 (be used for touching tongue) greater than described shank (being used for descaler is held in the hands 18 easily).

Shape resembles the marginal portion 22 of a dashboard (fender) and sees it is spill from shank 16 those sides, and provide one can contact or be connected the curved edge 24 of tongue 12 so that tongue is swiped, described edge is arcual, so that can touch the rear portion of tongue more easily, and do not need to increase the width of tongue cleaner.Be provided with a pair of slotted eye 26, they pass described supporting part 20, and are parallel to each side extension of supporting part, so that bigger flexibility to be provided.

As shown in Figure 3, generally anterior extend downwards from it at the rear portion 28 of tongue upper surface, and it is uncomfortable therefore touching the tongue rear portion with a straight tongue cleaner shown in aforementioned patent.In order more cosily to touch the rear portion 28 of tongue, according to the present invention, supporting part 20 is crooked with respect to shank 16, so as downward-sloping, thus edge 24 is contacted effectively with the rear portion 28 of tongue upper surface.In other words, supporting part 20 is positioned at a plane 30, this plane and plane, shank 16 place 32 at angle 34, and edge 24 is the directions that facing away from plane 32.Therefore, supporting part 20 is with respect to shank 16 34 extensions at angle.

Angle 34 can be selected as required, so that make supporting part 20 follow the gradient at tongue upper surface rear portion 28.Comparatively ideal is that this angle 34 is between about 20 degree and 40 degree.Better is that this angle 34 is about 27 degree.

Extend back at the recess 36 of tongue 12 centers in order to stretch into one effectively, the length direction of edgewise edge part 22 makes the marginal portion have certain profile, to have a relative darker core 38.Therefore, core has a degree of depth 40, and this degree of depth is greater than the degree of depth 42 towards supporting part 20 each side surface direction.

It is as follows that the size of suitable tongue cleaner can provide, but this only is to illustrate in order to be used for, rather than in order to limit.An example of suitable tongue cleaner 10 has one and is about 127 millimeters (5 inches) so that can make edge 24 touch the length 44 at tongue rear portion, one is about the shank length 46 of 88.9 millimeters (31/2 inches), and a thickness that is about 1.5875 millimeters (1/16 inches).Marginal portion 22 is transverse to one section distance 48 that is about 38.1 millimeters (11/2 inches) of shank 16 extend throughs.Distance 40 and 42 is about 6.35 millimeters (1/4 inches) and 3.175 millimeters (1/8 inch) respectively.Angle 34 is about 27 degree.The thickness at edge 24 can be about 0.3969 millimeter (1/64 inch).The width 50 of shank 16 can be about 9.525 millimeters (3/8 inches).Distance 52 can be about 38.1 millimeters (1/2 inches).

Though the present invention is described in detail; but; should be understood that, that the present invention can also implement in other mode that does not deviate from its ultimate principle, these other embodiment also should be within the protection domain of being determined by appended claims of the present invention.
