Abstract

The utility model relates to an anti-falling device for an interdental brush, in particular to an anti-falling device which is arranged in a rod body. The anti-falling device can effectively prevent the interdental brush from falling out of a brush holder or from rotating. The anti-falling device is mainly characterized in that a clamping part is arranged at a proper position of the rod body, the width of the clamping part is greater that that of the rod body, and the rod body and a grab handle are tightly fixed through the clamping part, so that the rod body is reliably fixed in the grab handle and is not easy to loose or rotate. The anti-falling device can prevent the rod body from falling off and sticking in a slit between teeth, and can prolong the service life of the interdental brush.

Description

Interdental brush prevent dropping device

Technical field

This utility model relates to a kind of dropping device that prevents of interdental brush, and it is deliberately to form the embedding section of pulling in the suitable place of the body of rod, can pull outside the section by embedding to strengthen and the binding of lever, makes the body of rod be difficult for getting loose, and is safer in the use.

Background technology

Traditional interdental brush sees also shown in Figure 1, and it mainly is comprised of bristle 11, the body of rod 12 and lever 13, and these body of rod 12 tops arrange bristle 11, and then planting in the lever 13 in the body of rod 12 belows, and is subjected to lever 13 to be coated and fixed on the inboard.

When using, handle 13 places that hold on the offensive, again bristle 11 is planted between slot, and utilize repeatedly pull bristle 11, the food debris in the slot is brushed out thereupon, right this body of rod 12 vertically penetrates in the lever 13, in case the strength of outwards extracting out is excessive, cause the body of rod 12 outwards to be extracted out together, not only cause easily interdental brush 1 to damage, more worry the body of rod 12 fracture and in the oral cavity that falls or be stuck in throat, quite dangerous.

The inventor specializes in the exploitation of various interdental brush, Cotton swab, dental floss stick, manufacturing work, know very well the disappearance that traditional interdental brush uses, and can't satisfy required, so do one's utmost to think hard solution, and the specialty that relies on itself reaches working experience for many years, finally after going through correction for several times, test and improving, initiate out this utility model.

The utility model content

The purpose of this utility model provides a kind of dropping device that prevents of interdental brush, and a kind of dress that comes off that prevents that is arranged in the body of rod particularly effectively avoids slot to brush by brush holder to deviate from or rotate.

For reaching above-mentioned purpose, this utility model provides a kind of dropping device that prevents of interdental brush, mainly formed by bristle, the body of rod and lever, this body of rod mutually twined by iron wire and form rectangular shaft-like, body of rod below is provided with the embedding section of pulling, this embedding is pulled the width of section greater than the width of the body of rod, bristle is inserted lever front end, one end of lever is provided with the land, and this body of rod is coated on the plastic cement shoot mode in the land of lever, and the body of rod can be fixed in to the gear of pulling can slippage in the lever.

Described interdental brush prevent dropping device, wherein, this embedding section of pulling is flight, hook sheet or the long sheet that colludes.

Described interdental brush prevent dropping device, wherein, this embedding section of pulling is arranged at center section part, back segment section or the epimere section of land.

When using, user is the pull body of rod repeatedly between slot usually, to utilize bristle to take advantage of a situation the food debris in the teeth space is brushed out, to keep the cleaning between slot, avoid breed bacteria, especially the embedding that relies on the body of rod the to extend section of pulling, the body of rod can be fixedly arranged in the lever, can not skid off along with the pull of user, safer in the use, and can effectively prolong service life of interdental brush, the tool result of use is splendid.

The specific embodiment

At first, see also shown in Figure 2, be three-dimensional exploded view of the present utility model, it mainly is comprised of bristle 21, the body of rod 22 and lever 23, this body of rod 22 is iron wire is twined mutually and to form rectangular shaft-like, again bristle 21 is inserted the body of rod 22 front ends, then with the body of rod 22 belows suitably the place deliberately outer Zhang Kuandu form the embedding section 221 of pulling, and outside lever 23, be equipped with a grip part 231, grip for user, and utilize the plastic cement ejaculation that the body of rod 22 is coated in the lever 23, and form an interdental brush 2 (as shown in Figure 3).

Then, please continue to consult shown in Figure 4, be the partial sectional view of this utility model interdental brush 2, this body of rod 22 is fixedly arranged in the land 232 of lever 23, and relies on width embedding the section 221 of pulling to produce the sawtooth effects outward, make the body of rod 22 can increase friction, more with lever 23 in land 232 combine closely, be difficult for getting loose and pull out or rotate, really support to pull and be engaged in the lever 23 with the seasonal embedding section 221 of pulling, needn't worry fully during use that the application of force is too large and the body of rod 22 is extracted out, quite safe.

During use, please then consult shown in Figure 5, the grip part 231 of the hand-held lever 23 of user, again bristle 21 is planted the tooth seam again with its extraction, make food debris between slot can be by the repeatedly pull of bristle 21 with removing, and bristle 21 has the difference of the difference of coarse wool and wide hair, for user according to the personal like.Yet differ in everyone slot gap; arranged dividing of size respectively; when user when pull is between slot repeatedly with bristle 21; if the slot gap is wide outside and narrow inside; be stuck in the slot after then causing easily the body of rod 22 to insert teeth space, this moment, user need apply a reverse outer strength with the body of rod 22 extractions, but excessive often can the causing outside the body of rod 22 of the application of force moved; make the body of rod 22 break away from the land of levers 23, cause interdental brush 2 to get loose and damage.Therefore this utility model deliberately arranges the embedding section 221 of pulling, and the embedding section 221 of pulling can closely be meshed with the land of lever 23, and effectively strengthen the body of rod 22 and be fixedly arranged in the lever 23, thus can not skid off because the application of force gets loose too greatly, very safe in the use.

About the pull structure of section 221 of embedding, please consult again shown in Figure 6, this embedding section 221 of pulling can be arranged at the optional position of the body of rod 22, make the embedding section 221 of pulling take shape in center section part 2321, back segment section 2322 (as shown in Figure 7) or the epimere section 2323 (as shown in Figure 8) of the land 232 of lever 23, all can reach and keep out the solid effect of pulling, make the body of rod 22 can combine closely in the land 232 of lever 23 interior be difficult for getting loose pull out.

As for the pull body of section 221 of embedding, please continue to consult shown in Fig. 9 A ~ Fig. 9 C, this embedding section 221 of pulling utilizes punching press or compressing, and outer Zhang Kuandu deliberately makes embedding pull section 221 greater than the width of the body of rod 22, and makes the embedding section 221 of pulling be flight 2210(Fig. 9 A), hook sheet 2211(Fig. 9 B) and long sheet 2212(Fig. 9 C that colludes), all become the sawtooth lamellar, can strengthen the fixedly (not shown) of pulling of supporting of the body of rod 22 and lever, prevent the puzzlement that the body of rod 22 gets loose, promote the safety of using.

In sum, the end of this utility model by the body of rod is set to the embedding section of pulling, the body of rod can be stablized pulls admittedly in lever, really prevent that the body of rod from outwards pullling along with user and get loose, really prolong the service life of interdental brush, and promote the safety of using, show and met novel patent requirement, and apply for front and find no identical product checking and approving patent formerly, also do not see publication, the whence proposes patent application in accordance with the law.
