Some embodiments of the present utility model are described in detail below with reference to fig. 1 to 4. The following embodiments and features of the embodiments may be combined with each other without conflict.

The embodiment of the utility model provides a polishing cup which is mainly applied to a dental polisher, and comprises a cup body 10 and an insert body 20 arranged in the cup body 10. The cup body 10 is substantially in the shape of a truncated cone, is hollow in the interior thereof, and has an opening 11 at one end in the axial direction thereof. The insertion body 20 has an insertion tip 21 facing the opening 11, the insertion tip 21 being for insertion into the gap of the gingival papilla, whereby the insertion tip 21 can be rotated in the gap of the gingival papilla when the cup body 10 is rotated, to perform cleaning and polishing functions.

It should be noted that, the polishing cup may be made of soft and elastic material, such as rubber, so as to avoid damage to the tissue inside the oral cavity, such as gum, while ensuring cleaning and polishing effects.

The insert body 20 is substantially cone-shaped, the insert body 20 is coaxially arranged with the cup body 10, the bottom surface of the cone is connected to the bottom surface of the inner cavity of the cup body 10, and the tip of the cone is the insert tip 21. Thereby ensuring that the insert 20 also rotates with the cup 10 around the center axis of the cup 10 when the cup 10 rotates around the center axis thereof, and ensuring the circle run-out accuracy of the insert tip 21.

The insert body 20 is embodied as a cone, and a plurality of first concave portions 22 are formed on the conical surface thereof at intervals in the circumferential direction, and the first concave portions 22 extend to the insert tip 21, so that polishing paste can be stored in the first concave portions 22, so that the polishing paste in the first concave portions 22 can flow to the insert tip 21 when polishing is performed, and the surface of the insert tip 21 can be attached with the polishing paste, thereby improving cleaning and polishing effects.

Wherein the first recess 22 may be a straight or curved groove extending to the bottom surface of the inner cavity of the cup body 10 so that more polishing paste may be stored.

In addition, a plurality of second concave parts 12 are arranged on the peripheral surface of the inner cavity of the cup body 10, and the second concave parts 12 can be blind holes arranged on the cup body 10 or can be used for storing polishing paste.

Specifically, all the second concave parts 12 are divided into at least two concave components, each concave component is circumferentially distributed at intervals, and each concave component comprises at least two second concave parts 12 axially distributed at intervals, so that polishing paste can be more uniformly distributed on the surface of the inner cavity of the cup body 10 when flowing out of the second concave parts 12, and better cleaning and polishing effects are achieved.

In this embodiment, a plurality of blades 30 are circumferentially spaced on the peripheral surface of the inner cavity of the cup body 10, the blades 30 extend from the bottom surface of the inner cavity of the cup body 10 to the opening 11, and the blades 30 are curved towards the circumferential direction of the cup body 10, so that when the polishing cup rotates in one direction (for example, anticlockwise direction as shown in fig. 4), the blades 30 block polishing paste so that the polishing paste cannot be easily thrown out in the cup body 10, and the retention time of the polishing paste is prolonged; and when the prophy angle is rotated in the other direction (e.g., clockwise as shown in fig. 4), it is sufficiently thrown out of the cup 10 by centrifugal action and by the guiding action of the vanes 30.

Specifically, all the blades 30 are distributed in an annular array about the central axis of the cup 10, each blade 30 has a first face 31 and a second face 32 opposite to each other in the circumferential direction of the cup 10, each of the first face 31 and the second face 32 is curved, and the curved directions of the first face 31 and the second face 32 are toward the same side of the blade 30, for example, the first face 31 is closer to the inner cavity circumferential surface of the cup 10 than the second face 32, so that when the polishing cup rotates in one direction (for example, counterclockwise as shown in fig. 4), the first face 31 blocks the polishing paste so that the polishing paste is not easily thrown out in the cup 10, and when the polishing paste rotates in the other direction (for example, clockwise as shown in fig. 4), the second face 32 guides the polishing paste so that the polishing paste is sufficiently thrown out of the cup 10.

Further, a plurality of ribs 40 are provided on the outer peripheral surface of the cup body 10 at a plurality of circumferential intervals, the ribs 40 being curved in the circumferential direction of the cup body 10, and the direction of the curvature of the ribs 40 being opposite to the direction of the curvature of the blades 30. Thus, the outer circumferential surface of the cup body 10 can also have tooth cleaning and polishing effects, and at the same time, when the polishing cups rotate in two directions respectively, the ribs 40 have the effect of retaining polishing paste or fully throwing out the polishing paste, for example, when the polishing cups rotate anticlockwise, the ribs 40 can fully throw out the polishing paste, and when the polishing cups rotate clockwise, the ribs 40 can block the polishing paste, so that the retention time of the polishing paste is longer.

The embodiment of the utility model also provides a dental polisher, which comprises the polishing cup of the embodiment, and therefore, the dental polisher also has corresponding beneficial effects.

In summary, embodiments of the present utility model provide a prophy angle and a dental polisher, the prophy angle including a cup body 10 and an insert 20 disposed within the cup body 10. The cup body 10 is substantially in the shape of a truncated cone, is hollow in the interior thereof, and has an opening 11 at one end in the axial direction thereof. The insertion body 20 has an insertion tip 21 facing the opening 11, the insertion tip 21 being for insertion into the gap of the gingival papilla, whereby the insertion tip 21 can be rotated in the gap of the gingival papilla when the cup body 10 is rotated, to perform cleaning and polishing functions.

Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present utility model, and not for limiting the same; although the utility model has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some or all of the technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit of the utility model.
