Description

Interdental brush

The present invention relates to an interdental brush, and more particularly to an interdental brush having a soft rib.

The existing interdental brush usually only has bristles. Because the volume of the interdental brush is small, the bristle bundle is relatively thin, so that the brushing force of the bristles on the tooth surface is insufficient to remove the plaque. Therefore, how to remove the plaque during use of the interdental brush is a problem to be solved.

Accordingly, it is an object of the present invention to provide an interdental brush that can apply a scraping force on a tooth surface to remove plaque.

Thus, in some embodiments, the present interdental brush comprises a body, a scraping unit and a bristle unit. The body has a cleaning portion and a hand portion at opposite ends. The scraping unit includes at least one soft rib disposed around the cleaning portion. The bristle unit includes a plurality of bundles of bristles disposed on the cleaning portion and interlaced with the at least one soft rib.

In some embodiments, the scraping unit includes a plurality of soft ribs spaced around the cleaning portion, and the bristles are interlaced with the soft ribs.

In some embodiments, the soft ribs are connected to spirally surround the cleaning portion.

In some embodiments, the cleaning portion is cylindrical and tapered toward an end remote from the handheld portion.

In some embodiments, the cleaning portion is cylindrical and tapers toward an end remote from the hand portion.

In some embodiments, the handpiece is in the form of a plate.

The novel has the following effects: by the matching of the scraping unit and the bristle unit, not only the foreign matter in the interdental seam can be removed, but also the plaque on the tooth surface on both sides of the interdental can be scraped off, and the better can be achieved. The effect of dental cleansing care.

Referring to FIG. 1 to FIG. 3, an embodiment of the present interdental brush comprises a body 1, a scraping unit 2 and a bristle unit 3.

The body 1 has a cleaning portion 11 and a hand portion 12 at opposite ends. In this embodiment, the cleaning portion 11 is cylindrical and tapered toward an end away from the hand portion 12 for extending into the interdental portion, and is tapered toward the end away from the hand portion 12, that is, freely The thinner the end, the convenient for the user to extend the cleaning portion 11 into the interdental seam and to adjust the position of the cleaning portion 11 relative to the teeth. For example, if the width of the interdental slit is narrow, the thin portion of the cleaning portion 11 (closer to the free end) may be located at the interdental portion, and if the width of the interdental slit is wider, the thicker portion of the cleaning portion 11 may be used (relaxed from the free portion) At the end) at the seam. The cleaning portion 11 is preferably cylindrical, but may not be limited to a cylinder, and other shapes of the cylinder may be implemented. The hand-held portion 12 is used for the user to hold the hand. In the embodiment, the hand-held portion 12 has a large shape in a plate shape to facilitate the user's finger to grasp, but the hand-held portion 12 is not limited to a plate shape. In other words, other shapes that can be held by hand can be implemented.

The scraping unit 2 includes a plurality of soft ribs 21 spaced around the cleaning portion 11. The soft rib 21 can be elastically deformed using a soft material such as silicone to avoid damaging the teeth. When the user extends the cleaning portion 11 into the interdental space, the soft ribs 21 can scrape the surface of the tooth to scrape the plaque. In the present embodiment, the soft ribs 21 are connected to each other and spirally disposed around the cleaning portion 11, so that the soft ribs 21 can be more effectively combined with the cleaning portion 11 when moving back and forth in the interdental space. The contact of the tooth surfaces on both sides of the interdental joint increases the effect of removing plaque. Of course, in a variant embodiment, the scraping unit 2 can be implemented with only one soft rib 21 disposed around the cleaning portion 11, as long as the soft rib 21 can contact the tooth surface at the interdental.

In the present embodiment, the bristle unit 3 includes a plurality of bundles of bristles 31 disposed on the cleaning portion 11 and interlaced with the soft ribs 21. The bristles 31 are used to remove foreign matter in the teeth.

In summary, by the cooperation of the scraping unit 2 and the bristle unit 3, not only the foreign matter in the interdental seam but also the plaque on the tooth surface on both sides of the interdental can be scraped off, and the plaque can be better. The effect of dental cleansing care.

However, the above is only the embodiment of the present invention, and when it is not possible to limit the scope of the present invention, all the simple equivalent changes and modifications according to the scope of the patent application and the contents of the patent specification are still This new patent covers the scope.
