The foregoing and other features, aspects and advantages of the present utility model will become more apparent from the following detailed description of the preferred embodiments, which proceeds with reference to the accompanying drawings.

Referring to fig. 2 to 3, a first preferred embodiment of the interdental brush 3 according to the present utility model comprises a handle 31, and a stem portion 32 (shown in phantom in fig. 3) extending outwardly from the handle 31; the rod 32 is adapted to enter the gap between any two teeth a and has a distal end 320 opposite to the handle 31, and the rod 32 is covered by a cleaning portion 33, i.e. the cleaning portion 33 is attached to the outer surface of the rod 32, and the cleaning portion 33 has a plurality of cleaning groups 330 and exposing sections 331 formed on the rod 32 in a ring shape, i.e. the plurality of cleaning groups 330 and exposing sections 331 cover the outer surface of the rod 32, so that the plurality of cleaning groups 330 and exposing sections 331 are designed to surround the rod 32 in a whole circle, and the plurality of cleaning groups 330 are arranged at intervals, so that each exposing section 331 is exposed between any two adjacent cleaning groups 330, i.e. is communicated with the outside.

Each cleaning set 330 of the cleaning portion 33 includes at least one bearing surface 3301 facing the direction of the handle 31 and encircling the stem 32 entirely, and at least one tapered surface 3302 extending from the bearing surface 3301 and tapering to form a truncated cone shape, wherein the tapered surface 3302 tapers toward the end 320 of the stem 32; in the first embodiment, each cleaning set 330 includes a single bearing surface 3301 and a single tapered surface 3302, and the adjacent cleaning sets 330 are disposed at intervals, so that each exposed section 331 is exposed between the bearing surface 3301 of one cleaning set 330 and the tapered surface 3302 of the adjacent other cleaning set 330.

Still further, in order to facilitate the insertion of the cleaning portion 33 along with the wrapped stem portion 32 into the gaps between the teeth a, the diameter of the bearing surface 3301 of the grip 31 may preferably be gradually reduced from the position closest to the grip 31 toward the position closest to the tip 320, so that the diameter of the bearing surface 3301 closest to the grip 31 may be larger than the diameter of the bearing surface 3301 closest to the tip 320, i.e., the size of the cleaning groups 330 may be tapered toward the tip 320 as shown in the drawing; the diameter of the shaft 32 is not limited, i.e. the diameter of the shaft 32 may be gradually reduced from the handle 31 toward the end 320, or the shaft 32 may maintain the same diameter (not shown), but the present utility model is merely illustrated by taking the dimensions of the cleaning group 330 and the diameter of the shaft 32 as examples.

Furthermore, a circumferential edge 3303 is formed at the junction of the bearing surface 3301 and the conical surface 3302, and the diameter of the circumferential edge 3303 is larger than that of the rod portion 32, so that when the interdental brush 3 is inserted into the tooth gap between the teeth a, the circumferential edge 3303 not only scrapes to effectively remove foreign matters in the tooth gap, but also contacts with the gum to achieve massage effect.

Referring to fig. 2 to 4, in use, the user holds the handle 31 and puts the end 320 of the stem 32 into the slot of any two adjacent teeth a to be cleaned, and since the tapered surfaces 3302 wrapping the stem 32 taper towards the end 320 of the stem 32 to form a truncated cone shape, the cleaning portion 33 and the stem 32 can be quickly and easily put into the slot, so that the use is more convenient, and the cleaning groups 330 are designed as a ring around the stem 32, i.e. by using the whole circle of the peripheral edge 3303 to have enough area to contact the gum for massaging the gum; in addition, during the process of pulling the cleaning portion 33 and the rod portion 32 out of the slot, the peripheral edge 3303 and the bearing surface 3301 of each cleaning group 330 are supported by the tapered surfaces 3302, so that the peripheral edge 3303 and the bearing surface 3301 have sufficient supporting force to promote the peripheral edge 3303 to effectively scrape off foreign matters, such as tartar attached to the surface of the tooth a, food residues remained in the slot, etc., and the scraped foreign matters can temporarily stay on the bearing surfaces 3301 of the cleaning groups 330, and also be accommodated in the space between the adjacent cleaning groups 330, i.e. the space where the exposed sections 331 are exposed outwards, and then the foreign matters are carried out of the slot along with the pulling operation, thereby effectively improving the cleaning effect of the teeth and the slot and increasing the convenience of use.

Referring to fig. 5 and 6, the second preferred embodiment of the interdental brush 3 according to the present utility model further comprises a handle 31, a stem 32, and a cleaning portion 33, and the detailed structural members and functions are the same as those of the first preferred embodiment, in particular: in this embodiment, each cleaning set 330 of the cleaning portion 33 includes two bearing surfaces 3301, 3301' and two tapered surfaces 3302, 3302', wherein one tapered surface 3302 extends from one bearing surface 3301 toward the end 320 and connects to the other bearing surface 3301', and the other tapered surface 3302' extends from the other bearing surface 3301' toward the end 320 and connects to the exposed section 331 adjacent to the other tapered surface 3302', so that the two continuous peripheral edges 3303, 3303' are formed in a tandem configuration, and the diameter of one bearing surface 3301 can be larger than the diameter of the other bearing surface 3301', so that the tapering is also beneficial for easy entry into the gaps, so that the overall configuration is beneficial for continuous scraping of food residues and tartar between the gaps by the plurality of peripheral edges 3303, 3303' of the same cleaning set 330, so that the same cleaning set 330 can have multiple scraping effects, and then the food residues and tartar can be more easily carried out of the gaps along with the pulling-out operation.

Referring to fig. 7, the third preferred embodiment of the interdental brush 3 according to the present utility model further comprises a handle 31, a stem 32, and a cleaning portion 33, and the detailed structural members and functions are the same as those of the first preferred embodiment, in particular: in this embodiment, the surface of the bearing surface 331 is concavely disposed to form a receiving space 3304, and the forming of the receiving space 3304 is also applicable to the second preferred embodiment, which is only exemplified in the figure, so that when the cleaning portion 33 and the rod portion 32 are inserted into the gaps, the scraped tartar and food residues can be contained in the receiving space 3304, so that the tartar and food residues can be more easily carried out of the gaps when the interdental brush 3 is pulled outwards, thereby improving the cleaning effect between the gaps.

In summary, the interdental brush of the present utility model has a plurality of cleaning groups and exposing sections, wherein the cleaning groups are arranged on the rod part through the cleaning part, each cleaning group comprises at least one whole circle of bearing surface surrounding the rod part, at least one conical surface gradually reducing from the bearing surface to the tail end of the rod part, and a peripheral edge positioned at the joint of the bearing surface and the conical surface; the tapered surface is utilized to easily enter the tooth gaps, and the peripheral edge and the bearing surface are supported by the tapered surface when the tapered surface is pulled outwards, so that the peripheral edge and the bearing surface have enough supporting force to scrape food residues or tartar remained in the tooth gaps, and enough area is contacted and massaged with the gum, thereby effectively improving the cleaning effect and the use convenience.
