Description

Technical Field

[0001] The utility model relates to the technical field of toothbrushes, in particular to an orthodontic toothbrush. Background Art

[0002] The beauty of teeth plays an increasingly obvious role in daily life and social occasions, making more and more people choose to wear braces to correct their teeth for aesthetic purposes. The time period for orthodontic treatment with braces is long, generally 1 - 2 years. During this period, the braces need to be worn continuously by the wearer, and the attached devices or accessories bonded to the tooth surface cannot be removed. Due to the influence of the attached devices or accessories bonded to the tooth surface, it is extremely difficult to clean the posterior teeth, especially the innermost teeth. Moreover, due to the difficulty in thorough cleaning, dental caries often occur. When using an ordinary toothbrush to clean teeth, it takes a long time and the cleaning effect is not good.

[0003] Currently in the market, whether it is a conventional toothbrush or an orthodontic toothbrush, the brush head is straight without curvature. When cleaning the posterior teeth, especially the distal surface of the posterior tooth attachments, due to the lack of curvature of the brush head, the user will try to clean at an angle as far away from the midline of the occlusal surface as possible. However, such an action will cause discomfort to the buccal mucosa. Inserting the brush head too deeply inward will also stimulate the pharynx, and the cleaning effect is still difficult to meet the expectation.

[0004] In view of this, this application is specifically proposed. Content of the Utility Model

[0005] The purpose of the utility model is to provide an orthodontic toothbrush to solve the problems raised in the above background art.

[0006] To solve the above technical problems, an orthodontic toothbrush provided by the utility model includes:

[0007] A brush handle for the user to hold.

[0008] A brush head detachably mounted on the brush handle, with its upper end bent inward to form an outer arc-shaped surface and an inner arc-shaped groove.

[0009] Brush bristles, including an upper tuft, a middle tuft, and a lower tuft all located inside the arc-shaped groove, and the upper tuft, middle tuft, and lower tuft present a semi-surrounding shape.

[0010] Further, the upper tuft is located at the upper part of the arc-shaped groove, the middle tuft is located at the middle part of the arc-shaped groove, and the lower tuft is located at the lower part of the arc-shaped groove.

[0011] Further, there is a gap between the bottom ends of the upper tuft, middle tuft, and lower tuft, and the top ends of the upper tuft, middle tuft, and lower tuft are mutually adhered.

[0012] Further, the side of the middle hair bundle away from the arc-shaped groove is an arc surface structure, and the sides of the upper hair bundle and the lower hair bundle away from the arc-shaped groove have an inclined surface close to the arc surface structure and a slope surface away from the arc surface structure.

[0013] Further, a slot is provided at the top end of the brush handle, and a plug rod that can be inserted into the slot is provided at the bottom end of the brush head.

[0014] Further, the upper part of the brush handle is small, the lower part is relatively large, and the anteroposterior diameter is relatively small. The cross-section of the brush handle is oval.

[0015] Further, it further includes a base, the base includes a seat body in a bowl-shaped structure and a groove provided on the seat body, and the bottom end of the brush handle can be inserted into the groove.

[0016] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0017] 1. In the present utility model, by bending the upper end of the brush head inward to form an outer arc-shaped curved surface and an inner arc-shaped groove, the arc-shaped design effectively avoids the situation that a conventional straight brush head directly pokes the pharynx or buccal mucosa when cleaning the posterior teeth, and to the greatest extent avoids pharyngeal discomfort or buccal mucosa irritation.

[0018] 2. In the present utility model, the bristles composed of the upper hair bundle, the middle hair bundle and the lower hair bundle are in a shape that fits the shape of the attachments adhered to the tooth surface. In particular, the bristles at the tip can effectively clean the distal surface of the attachments, and at the same time can also clean other areas of the attachments and the tooth surface.

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0028] Please refer to Figures 1-3 , the present invention provides a technical solution, including:

[0029] A brush handle 1 for a user to hold;

[0030] A brush head 2 detachably installed on the brush handle 1, with its upper end bent inward to form an outer arc-shaped surface and an inner arc-shaped groove;

[0031] Brush bristles 3, including an upper tuft 301, a middle tuft 302, and a lower tuft 303 all located inside the arc-shaped groove. The upper tuft 301, the middle tuft 302, and the lower tuft 303 present a semi-surrounding shape.

[0032] Refer to Figure 1 , the upper tuft 301 is located at the upper inner side of the arc-shaped groove, the middle tuft 302 is located in the middle of the arc-shaped groove, and the lower tuft 303 is located at the lower part of the arc-shaped groove.

[0033] Refer to Figure 1 , there is a gap between the bottom ends of the upper tuft 301, the middle tuft 302, and the lower tuft 303, and the top ends of the upper tuft 301, the middle tuft 302, and the lower tuft 303 are in contact with each other.

[0034] Refer to Figure 3 , the side of the middle tuft 302 away from the arc-shaped groove is an arc surface structure, and the sides of the upper tuft 301 and the lower tuft 303 away from the arc-shaped groove have an inclined surface close to the arc surface structure and a slope surface away from the arc surface structure.

[0035] Refer to Figure 1 , a slot is provided at the top end of the brush handle 1, and a plug rod that can be inserted into the slot is provided at the bottom end of the brush head 2. When the brush bristles 3 need to be updated after being used for a period of time, only the brush bristles 3 need to be replaced each time, while the brush handle 1 is retained, saving production costs and resources and being more environmentally friendly.

[0036] Refer to Figure 2 , the upper part of the brush handle 1 is small, the lower part is relatively large, and the front-back diameter is relatively small. The cross-section of the brush handle 1 is oval, which is beneficial for holding and grasping. At the same time, the shape of the brush handle similar to that of a bowling ball makes the center of gravity of the toothbrush as low as possible, avoiding the situation of falling out of the tooth cup due to the upper center of gravity when placed in the tooth cup.

[0037] Refer to Figure 3 , further comprising a base 4, the base 4 includes a seat body in a bowl-shaped structure and a groove provided on the seat body, the bottom end of the toothbrush handle 1 can be inserted into the inside of the groove. To avoid the problem that bacteria are likely to breed when the toothbrush is placed in a closed bathroom for a long time, the toothbrush can be placed in a well-ventilated space. However, there is a possibility of dropping when directly placed in an external space. Placing the toothbrush on the base 4 can make the placement of the toothbrush more stable.

[0038] Working principle: The outer side of the brush head 2 is arc-shaped, which matches the shape of the buccal mucosa migrating to this area. The upward and inward bending shape of the upper end of the brush head 2 can also avoid directly stimulating the posterior pharyngeal wall to a certain extent. The bristles 3 are composed of three parts, namely the upper tuft 301, the middle tuft 302, and the lower tuft 303. The morphological structures of the upper tuft 301 and the lower tuft 303 are similar, and their shapes are similar to the spires of the roof of an European Gothic building. The inclined surfaces of these two parts close to the middle tuft 302 can clean the mesial and distal surfaces of the attachments, while the inclined surfaces away from the middle tuft 302 can clean the corresponding tooth surfaces. The design of the bristles 3 not only helps to increase the cleaning area, but also can well clean the distal surfaces and gingival surfaces of the posterior tooth buccal attachments (including horizontal rectangular attachments and vertical rectangular attachments), and at the same time can also clean other areas of the attachments and the tooth surfaces.
