[0028] The preferred embodiments of the present invention will be described in more detail below. Although the preferred embodiments of the present invention are described below, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0029] The utility model provides an orthodontic toothbrush head, comprising:

[0030] The brush body has a U-shaped cross section, and at least three first bristle groups are arranged in the horizontal direction of the brush body, and each first bristle group is arranged along the length direction of the brush body;

[0031] A second bristle group, an inner oblique bristle group and an outer oblique bristle group are respectively arranged at both ends of the brush body. The second bristle group is arranged between the inner oblique bristle group and the outer oblique bristle group. The inner oblique bristle group and the outer oblique bristle group at the same end are symmetrically arranged. The inclination angle of the outer oblique bristle group is 40° to 50°. When the orthodontic toothbrush head contacts the tooth surface, the second bristle group is in a vertical relationship with the tooth surface.

[0032] Specifically, in the orthodontic toothbrush head, the brush body is used as a supporting surface, and at least three first bristle groups are arranged on the U-shaped inner side of the brush body. The first bristle groups are evenly distributed on the inner circumferential surface of the brush body. In addition, a second bristle group, an inner oblique bristle group and an outer oblique bristle group are respectively arranged on the two ends of the brush body. The second bristle group is centrally arranged between the inner oblique bristle group and the outer oblique bristle group, and the inner oblique bristle group and the outer oblique bristle group are also symmetrically arranged. When the brush head is used to clean the upper teeth wearing orthodontic braces, the brush head is placed horizontally, and the inner opening direction of the brush body is perpendicular to the outer surface of the teeth. When the brush body moves to be opposite to the bracket, the first bristle group will clean the outer surface of the bracket and the archwire, and the second bristle group at the upper end will contact vertically with the teeth located on the upper part of the bracket, which can actively clean the teeth located on the upper part of the bracket. The inner oblique bristle group at the upper end can extend into the angle between the upper part of the bracket and the tooth surface, so as to clean the upper gap between the bracket and the teeth, and the outer oblique bristle group at the upper end can extend into the gingival sulcus. In this way, only a simple horizontal movement of the brush head is required to cover all the tooth surfaces and dead corners that need to be cleaned on the upper part of the bracket during movement; in addition, the second bristle group and the inner oblique bristle group at the lower end clean the same area as the corresponding bristle group at the upper end, and the outer oblique bristle group at the lower end contacts the lower end surface of the upper teeth, and can clean the lower end surface of the teeth during the horizontal movement of the brush head. When the brush head is used to clean the area of ​​teeth without brackets, the first bristle group inside the brush body can clean the outer surface of the arch wire, and the side of the inner-slanted bristle groups at both ends close to each other is close to the inner surface of the arch wire. After adjusting the relative height between the brush head and the teeth, the inner-slanted bristle group can fit the inner surface of the arch wire. During the translation of the brush head, the inside of the arch wire is cleaned. At the same time, the side and end of the inner-slanted bristle group away from each other can also clean the tooth surface blocked by the arch wire, and the second bristle group and the outer-slanted bristle group at the end clean the same position as the cleaning position facing the teeth with alveolar sockets. Setting the outward inclination angle of the outer-slanted bristle group within this range can make the outer-slanted bristle group easily enter the gingival sulcus, and combined with the user's horizontal tremor action, it can achieve an effect close to the Bass brushing method.

[0033] Optionally, the extending direction of the first bristle group is the same as the radial direction of the brush body.

[0034] Specifically, the first bristle groups are all arranged in the middle of the brush body, and the middle of the brush body is in an arc shape. Each first bristle group is arranged along the radial direction of the brush body, so that when the first bristle groups contact the bracket or the archwire, multiple first bristle groups can completely cover the outer surface of the alveolar socket, the first bristle group in the middle contacts the archwire and the joint between the archwire and the bracket, and the first bristle groups on both sides contact the outer surface of the bracket, so that when the brush head moves laterally, the first bristle group can clean the bracket and the archwire protruding from the tooth surface. As the relative height of the brush head and the teeth is continuously adjusted, the first bristle group can completely contact the outer surface of the bracket, ensuring that the outer surface of the bracket and the joint between the bracket and the archwire are cleaned without dead angles.

[0035] Optionally, a top cross-section of the second bristle group is larger than a cross-section of an end portion of the brush body.

[0036] Specifically, the second bristle groups at both ends are arranged in a trapezoidal shape. The closer the second bristle group is to the tooth surface, the wider the second bristle group is. In this way, the contact area between the second bristle group and the exposed surface of the teeth is larger. There is no need to adjust the height of the brush head relative to the teeth multiple times to complete the cleaning of the tooth surface, thereby improving the brushing efficiency.

[0037] Optionally, the top gap of the inner-angled bristle groups at both ends is smaller than the diameter of the arch wire.

[0038] Specifically, the inner oblique bristle groups arranged at both ends make the gap between the tops of the inner oblique bristle groups at both ends smaller than the diameter of the arch wire through the inclination angle and the length of the inner oblique bristle groups. In this way, when the brush head is cleaning teeth with brackets, the sides of the inner oblique bristle groups close to each other can contact the arc surface and the side surface of the bracket. In this way, the cooperation of the inner oblique bristle group and the first bristles can completely clean the exposed part of the bracket to avoid dead corners. When the brush head is cleaning teeth with only arch wires on the outside, the inner oblique bristles The side parts of the group that are close to each other clean the inner surface of the arch wire, and the top of the inner oblique bristle group cleans the tooth surface opposite to the arch wire. As the inner surface of the arch wire is cleaned, the brush head can be rotated around the axis of the arch wire at a certain angle, so that the side of the inner oblique bristle group can clean the back of the arch wire. At the same time, the inner oblique bristle group is inserted obliquely from one end of the brush body at the back of the arch wire to the other end of the brush body. The inner oblique bristle group can clean the tooth surface near the arch wire from different angles, thereby improving the cleanliness of the tooth surface.

[0039] Optionally, the top cross-section of the first bristle group located in the middle of the brush body is not smaller than the diameter of the arch wire.

[0040] Optionally, the height of the first bristle group located in the middle of the brush body is greater than that of the remaining first bristle groups.

[0041] Specifically, among the multiple first bristle groups arranged in the middle of the brush body, the top cross-section of the first bristle group located in the middle is arranged so that when cleaning teeth with brackets, the first bristle group in the middle can completely cover the exposed surface of the arch wire, and the bristle groups on both sides of the first bristle group in the middle can also extend into the gap between the arch wire and the bracket, so that the arch wire and the surrounding area can be fully cleaned; in addition, the length of the first bristle group in the middle is greater than that of the first bristle groups on the other two sides, the first bristle group in the middle is in contact with the arch wire, and the first bristle groups on both sides are in contact with the outer surface of the bracket, and the shapes of the multiple first bristle groups are arranged in accordance with the shape of the bracket, so as to ensure that the first bristle group in the middle is in full contact with the arch wire, so that in the process of lateral movement of the brush head, the arch wire and the outer surface of the bracket can be cleaned without dead ends.

[0042] Optionally, the end of the brush body is semicircular, and the width of the end of the brush body is greater than the width of the middle of the brush body.

[0043] Specifically, the end of the brush body is set to be semicircular, and the end is wider than the thickness of other positions of the brush body. Such an enlarged structure at the end of the brush body can set the inclination angles of the inner oblique bristle group and the outer oblique bristle group to be larger, so that the inner oblique bristle group can be more easily inserted between the bracket and the tooth surface, and the contact area between the inner oblique bristle group and the tooth surface behind the arch wire can be increased, thereby improving the cleaning efficiency of the inner oblique bristle group on the tooth surface. As the inclination angle of the outer oblique bristle group increases, it is convenient for the outer oblique bristle group to extend into the gingival sulcus; in the process of cleaning unobstructed tooth surfaces, the second bristle group is the most important bristle. Since the top cross-section of the second bristle group needs to be larger than the end cross-section of the brush body, the end width of the brush body is increased, so that the cross-section of the second bristle group does not need to change too much, so that the fluff of the second bristle group is more compact, the friction between the second bristle group and the tooth surface is greater, and the cleaning effect is better.

[0044] The utility model also provides an orthodontic toothbrush, comprising:

[0045] According to the above-mentioned orthodontic toothbrush head, the brush body and the connector are an integrally formed structure;

[0046] The toothbrush handle is detachably connected to the connector.

[0047] Optionally, the toothbrush handle is an electric toothbrush handle or a manual toothbrush handle.

[0048] Specifically, the brush handle is connected to the brush head through a connector, and the brush head and the connector are arranged as an integrated structure, which is convenient for the assembly of the orthodontic toothbrush. The connector is arranged in an enlarged shape, and a socket is opened at the bottom of the connector. A plug is arranged at the fixed part of the toothbrush handle, and a spring bead is arranged on the plug. When the plug is inserted into the socket, it is snap-fitted and fixed by the spring bead, and the tooth surface can be cleaned by an electric handle or a manual handle.
