Description

Soft interdental brush

The present invention relates to a soft interdental brush, and more particularly to a soft interdental brush that can be used to massage gums and has a descaling function.

Referring to FIG. 1 , the conventional soft interdental brush 9 includes a handle 91 and a brush bar 92. The handle 91 is coupled to one end of the brush bar 92, and the handle 91 is preferably in the form of a sheet. For the user to hold.

The conventional soft interdental brush 9 is characterized in that the brush bar 92 comprises a body 921 and a plurality of elastic convex cones 922. The body 921 has a long rod shape, and one end of the body 921 is connected to one end of the handle 91, and the rod diameter of the body 921 is preferably tapered from the end toward the other end. The plurality of elastic convex cones 922 are protruded from the radially outer circumferential surface of the body 921, and the plurality of elastic convex cones 922 are preferably divided into an array, and each set of elastic convex cones 922 is axially spaced along the body 921. arrangement.

However, although the above-described conventional interdental brush 9 can be used to extend the teeth between the teeth and the gums to descale and massage the gums, since each elastic convex cone 922 has a tapered shape facing away from the end of the body 921, That is, the surface actually contacting the gingival area after the insertion into the tooth gap is actively small, and the effect of massaging the gums with the soft interdental brush 9 is not so good. In addition, since each of the elastic tabs 922 is connected to at most only the outer circumference of the brush bar 92 In part, it is apparent that during the process of removing tartar and being subjected to external force, it is apparent that it is impossible to maintain good strength to push or pull the tartar out of the tooth gap.

Therefore, efforts should be made to improve the above-mentioned conventional soft interdental brush 9, in order to simultaneously improve the massage and descaling effects.

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. The plurality of elastic tabs are coupled to the outer peripheral surface of the body, and each of the elastic tabs extends substantially along the outer circumferential direction of the body. 180 degree. The handle is coupled to one end of the body.

The plurality of elastic tabs of the present invention are divided into a first tab group and a second tab group, the first tab group is located on a side of the body in a radial direction, and the second tab group is located on the body. The other side in the radial direction.

The elastic tabs of the first tab group of the present invention are disposed offset from the elastic tabs of the second tab group in the axial direction of the body.

The plurality of elastic tabs of the present invention are non-perpendicularly inclined with respect to the axial direction of the body, and the plurality of elastic tabs are connected to form a spiral shape.

The body of the present invention has a connecting end and a free end. The connecting end is connected to the handle, and each of the elastic tabs is located between the connecting end and the free end.

Fig. 5 is a perspective view showing still another application example of the preferred embodiment of the present invention.

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

Referring to Figures 2 and 3, 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 coupled to the outer peripheral surface of the body 21 and located between the connecting end 211 and the free end 212, and each of the elastic tabs 22 extends substantially 180 degrees along the outer circumferential direction of the body 21. To form an outer edge 221 facing away from the body 21. In more detail, the plurality of elastic tabs 22 can be divided into a first tab group 22a and a second tab group 22b, wherein the first tab group 22a is located on a side of the body 21 in the radial direction. And the second tab group 22b is located on the other side in the radial direction of the body 21. On the axis of the body 21 Upward, the elastic tab 22 of the first tab group 22a can be disposed just offset from the elastic tab 22 of the second tab group 22b. In addition, the plurality of elastic tabs 22 may also be non-perpendicularly inclined with respect to the axial direction of the body 21, and the first tab group 22a and the second tab group 22b are inclined in the same direction so as to be the plurality of The elastic tabs 22 are connected to form a spiral extending between the connecting end 211 and the free end 212.

Referring to FIG. 4 together, since each of the elastic tabs 22 extends 180 degrees along the outer peripheral surface of the body 21, each of the elastic protrusions is used when the user massages the gums with the soft interdental brush of the present invention. The length of the outer edge 221 of the sheet 22 facing away from the body 21 is sufficient to provide sufficient surface area to press the gums, which greatly enhances the massaging effect relative to conventional soft interdental brushes. Moreover, since each of the elastic tabs 22 is substantially integrated with the outer circumferential surface of the body 21 by 180 degrees, when the user removes the tartar by the soft interdental brush of the present invention, when the tartar is stuck in the body 21 Between the two axially adjacent two elastic tabs 22, the two elastic tabs 22 can provide sufficient structural strength to push/pull the tartar from the tooth gap, so that it is greatly improved compared with the conventional soft interdental brush. Descaling ease of use.

Please refer to Fig. 5, the handle 1 of the soft interdental brush of the present invention can also be in the form of a floss stick for the user to first shake the tartar in the tooth gap with the floss of the floss bar. Loosen and then remove the tartar with the soft interdental brush.

In summary, the present invention mainly extends through the outer circumferential direction of the main body 21 and substantially surrounds the outer circumference of the outer circumference of the body 21 to increase the outer circumference of the body 21 to increase the back side of the body 21 The length of the rim 221, therefore, not only provides sufficient surface area to press the gums, but also provides sufficient structural strength to push/pull the tartar out of the teeth. Accordingly, the soft interdental brush of the present invention can effectively improve the efficiency and convenience of use.
