The main purpose of the present invention is to provide a soft interdental brush having a sufficient surface area to massage the gums and also having sufficient structural strength to remove tartar from the teeth, thereby effectively improving the efficiency and convenience of use.

In order to achieve the above purpose, the soft interdental brush of the present invention comprises a brush bar and a handle. The brush bar has a body and a plurality of elastic tabs. The body has a long rod shape and has a free end and a connecting end. The plurality of elastic tabs are coupled to the outer peripheral surface of the body and are located at the free end and the connection. Between the ends, each of the elastic tabs extends substantially a predetermined angle along the outer circumferential direction of the body to form an outer edge facing away from the body. The handle is coupled to one end of the body.

The plurality of elastic tabs of the present invention form two first tab groups and two second tab groups, and the elastic tabs in the two first tab groups are convexly disposed on the body along opposite radial directions of the body. The outer peripheral surface of the second pair of tabs is also radially protruded from the outer peripheral surface of the body.

The two first radial groups of the present invention and the four radial systems protruding from the two second convex groups are equally divided into outer peripheral surfaces of the body.

The elastic tab of one of the two first tab groups of the present invention is inclined toward the connecting end, and the elastic tab of the other of the two first tab sets is inclined toward the free end; the second and second The elastic tab of one of the sets of the tabs is inclined toward the connecting end, and the other of the second set of the second tabs is The elastic tab is inclined toward the free end.

In the axial direction of the body, the elastic tabs in the two first tab groups are offset from the elastic tabs in the second tab group.

The above and other objects, features, and advantages of the present invention will become more apparent from the aspects of the invention.

Referring to FIGS. 2 to 4, the soft interdental brush of the preferred embodiment of the present invention comprises a handle 1 and a brush bar 2, wherein the brush bar 2 is coupled to one end of the handle 1. In order to have a better structural strength, the brush bar 2 may have a core integrally formed at the end of the handle 1, and the brush bar 2 further has a surface covering the core, and the surface is The elastic material is suitable for contact with the gums, but the brush bar 2 is not limited to the core portion and the surface portion.

In detail, the brush bar 2 of the soft interdental brush of the preferred embodiment of the present invention comprises a body 21 and a plurality of elastic tabs 22, wherein the body 21 is preferably rod-shaped, and the opposite ends thereof are one. The connecting end 211 and the free end 212 constitute the end of the brush bar 2 coupled to the handle 1, and the body 21 is tapered by the connecting end 211 toward the free end 212. Each of the elastic tabs 22 is tied The outer peripheral surface of the body 21 is disposed between the connecting end 211 and the free end 212, and each of the elastic tabs 22 extends substantially a predetermined angle along the outer circumferential direction of the body 21 to form a back surface. An outer edge 221 of 21.

More specifically, the plurality of elastic tabs 22 form two first tab sets 22a and two second tab sets 22b. The elastic tabs 22 of the two first tab groups 22a are protruded from the outer circumferential surface of the body 21 in opposite radial directions of the body 21; similarly, the elastic tabs in the second second tab group 22b 22, the second radial direction of the body 21 is oppositely disposed on the outer peripheral surface of the body 21, wherein the four first protrusions 22a and the second second group 22b are preferably radially extended. The outer peripheral surface of the body 21 is evenly divided, that is, the angle between any two adjacent radial directions is 90 degrees. In addition, the elastic tab 22 of one of the two first tab groups 22a is inclined toward the connecting end 211, and the elastic tab 22 of the other of the two first tab groups 22a is inclined to the free end 212. . Similarly, the elastic tab 22 of one of the two second tab groups 22b is inclined toward the connecting end 211, and the elastic tab 22 of the other of the two second tab groups 22b is directed to the free end 212. tilt. In addition, in the axial direction of the body 21, the elastic tabs 22 of the two first tab groups 22a are disposed offset from the elastic tabs 22 of the two second tab groups 22b.
