Detailed Description
The present invention will be further described with reference to the accompanying drawings, and it should be noted that the following embodiments are based on the technical solution, and the detailed embodiments and the specific operation processes are provided, but the protection scope of the present invention is not limited to the embodiments.
As shown in fig. 1-4, a cleaning brush for tooth gaps comprises a fixed handle 1 and a brush head, wherein the brush head comprises a brush part 2 and a connecting rod 3, the brush part 2 is fixedly arranged at the upper part of the connecting rod 3, and the lower part of the connecting rod 3 is fixedly connected with the fixed handle 1; the bristle part 2 is radially implanted on the connecting rod 3 in a surrounding manner; the bristle part 2 comprises a front end bristle group 21, a middle bristle group 22 and a rear end bristle group 23; the front end bristle group 21 is disposed downward from the top end of the connecting rod 3 so that the top end of the front end bristle group 21 can form a tip having bristles; the middle bristle group 22 is arranged between the front end bristle group 21 and the rear end bristle group 23; the front end bristle group 21 includes a plurality of front end bristle tufts 211, each front end bristle tuft 211 having a plurality of bristles; the bristle length of the plurality of front end bristle tufts 211 is gradually shortened from top to bottom; the tops of the bristles of the front bristle tufts 211 are inclined downward with respect to the long axis direction of the connecting rod 3, and the front bristle tufts 211 are tapered; the rear end bristle group 23 includes a plurality of rear end bristle tufts 231, each rear end bristle tuft 231 having a plurality of bristles; the tops of the bristles of the rear end bristle tufts 231 are inclined upward with respect to the longitudinal direction of the connecting rod 3, and the rear end bristle tufts 231 have an inverted-pointed structure; the bristle length of the plurality of rear end bristle tufts 231 is gradually shortened from bottom to top; the middle bristle group 22 comprises a plurality of middle bristle tufts 221, each of the middle bristle tufts 221 having a plurality of bristles, the middle bristle tufts 221 having a bristle length less than the bristle length of the front end bristle tufts 211 and the rear end bristle tufts 231; the bristles of the plurality of middle bristle tufts 221 are arranged perpendicular to the connecting bar 3.
In the present embodiment, the front end bristle tufts 211 and the rear end bristle tufts 231 are symmetrically arranged with respect to the middle bristle tufts 221, and the bristles of the front end bristle tufts 211 and the rear end bristle tufts 231, which are symmetrical to each other, have the same length; the bristle length of the plurality of front end bristle tufts 211 is gradually shortened from top to bottom, and the downward inclination angle of each front end bristle tuft 211 is consistent; the bristle length of the plurality of rear end bristle tufts 231 gradually increases from top to bottom, and the angle at which each of the rear end bristle tufts 231 is spread upward is the same. The symmetrical arrangement of the front end bristle group 21 and the rear end bristle group 23 can ensure that the interdental cleaning brush can fill different types of interdental gaps as much as possible, and is a design pursuing universality. In actual production practice, the lengths of the bristles of the front end bristle group 21, the middle bristle group 22 and the rear end bristle group 23 and the inclination angles of the bristles can be set reasonably according to actual conditions. According to the difference of the length of the arranged bristles and the inclination angle, the interdental cleaning brush can be suitable for interdental gaps with different widths, can be customized according to users, and has strong economical efficiency and practicability.
According to the interdental cleaning brush, the structure of the front end bristle cluster 211 is pointed, so that the structure of the front end bristle cluster 21 is similar to an arrow, the bristles of the front end bristle cluster 211 incline downwards by virtue of the pointed top end of the front end bristle cluster 21, the interdental cleaning brush can easily enter interdental gaps with different widths, meanwhile, the structure of the rear end bristle cluster 231 is inverted, the interdental cleaning brush forms an unfolded structure by virtue of the front end bristle cluster 21 when exiting after entering the interdental gaps, the bottom of the rear end bristle cluster 23 is pointed, the bristles of the rear end bristle cluster 231 are unfolded upwards, the angle of the bristles when being extracted from the interdental gaps can conform to the extraction direction, the extraction process is simple and labor-saving, the teeth on two sides of the interdental gaps can be wiped once again, and the cleaning force is improved. Therefore, the interdental cleaning brush can easily enter and exit gaps between teeth, and the tooth brushing efficiency is improved. In the present embodiment, the front end bristle tufts 211 and the rear end bristle tufts 231 are pointed and inverted pointed, in particular.
As the brush head part is radially and circularly implanted on the connecting rod 3, when the interdental cleaning brush enters a wider interdental gap, the radial bristles can be spread to fill the space in the gap and completely contact the side surfaces of two teeth forming the gap, so that food residues and bacteria in the interdental gap can be effectively cleared, and a better oral cleaning effect can be achieved.
When the interdental cleaning brush enters the gaps between teeth, the front end bristle cluster 211 and the rear end bristle cluster 231 can respectively cling to the sides of two teeth forming the gaps, because of the pointed structures of the front end bristle cluster 211 and the rear end bristle cluster 231, and when the interdental cleaning brush moves in the gaps, the inclined bristles of the front end bristle cluster 211 and the rear end bristle cluster 231 can clean the sides of the teeth in a scraping manner from two directions, so that bacteria deeply hidden in the gaps between the teeth can be scraped and taken away more effectively; meanwhile, the front end bristle group 21 and the rear end bristle group 23 are separated by a distance due to the existence of the middle bristle group 22, the front end bristle group 21 and the rear end bristle group 23 which face different bristle directions are prevented from being influenced and resisted mutually, and in the case of missing cleaning of some parts, the middle bristle group 22 which is shorter than the front end bristle group 21 and the rear end bristle group 23 can clean a narrower part in a gap between teeth, so that the cleaning effect is better ensured.
Further, a connecting groove 13 is arranged in the middle of the fixing handle 1, and the connecting groove 13 extends from the top of the fixing handle 1 to the lower part of the holding hand along the long axis direction of the fixing handle 1; the connecting groove 13 is matched with the connecting rod 3, and the lower part of the connecting rod 3 is fixedly connected in the connecting groove 13. Through the connection of the connecting groove 13 and the connecting rod 3, the brush head part can be more stably connected with the fixed handle 1, the condition that the brush hair part 2 is easily separated from the fixed handle 1 is avoided, and the brush hair part 2 is prevented from being lost.
Further, the fixing handle 1 includes a protruding portion 11 and a connecting portion 12, the protruding portion 11 is disposed above the connecting portion 12; the protruding part 11 and the connecting part 12 are of an integrally formed structure. The connecting portion 12 is used for connecting a holding handle, the protruding portion 11 can prevent the connected holding handle from touching the bristle portion 2, and the protruding portion 11 plays a role in separating the bristle portion 2 from the connecting portion 12. For convenience of use, the interdental cleaning brush is often connected to a grip handle, which may be made in an oval, flat, elongated shape, etc., so as to be held by a hand of a user for use.
The tooth gap cleaning brush has the advantages of small volume, simple structure and portability.
