Description

Technical Field

[0001] The utility model relates to the technical field of brush products, in particular to a brush head and a toothbrush used in a teeth correction period. Background Art

[0002] Wearing dental braces increases the probability of food residues remaining in the oral cavity. The prior art has proposed various solutions to this problem. For example, Chinese patent document CN 209135609 U discloses a toothbrush applied to braces, in which bristles are evenly arranged on the bottom surface, left side surface, right side surface and front side surface of the brush head to clean the inner surfaces of the braces. However, the disadvantage is that when the bristles on one surface are working, the bristles on other planes are likely to cause direct friction with the skin inside the oral cavity, resulting in poor comfort in use. Chinese patent document CN 219894963U discloses an orthodontic brush head and a toothbrush, wherein the bristles thereof include first bristles, second bristles and third bristles, wherein the first bristles located in the middle are used to clean the orthodontic attachments, and the second bristles and third bristles on both sides are used to clean the gums and tooth roots, etc. Since the first bristles are shorter, they can match the shape of the orthodontic attachments protruding from the teeth and the shape of the teeth, and the first bristles are harder, so they can clean the parts of the orthodontic attachments that are difficult to clean, and the second bristles and third bristles on both sides are softer, so they are convenient for cleaning the gums and tooth roots. The disadvantages of the orthodontic brush head are as follows: (1) the soft bristles on both sides often rub against the irregular body, and the top is easily deformed; (2) the shorter hard bristles in the middle are difficult to clean the gap between the dental braces and the teeth; (3) since the first bristles at the top of the brush head are lower in height, it is difficult to clean the inner surface of the wisdom teeth or teeth. Utility Model Content

[0003] The utility model aims to overcome the deficiencies of the prior art and provide a brush head and a toothbrush for use during orthodontic treatment, which are conducive to comprehensive cleaning of teeth and orthodontic appliances, and the soft bristle part is not easy to fall over.

[0004] In order to achieve the above purpose, the technical solution of the utility model is as follows:

[0005] Brush heads for orthodontic treatment, including

[0006] A base portion, used to provide support for the bristle portion;

[0007] The bristle part is fixed on the base part, and includes a soft bristle part and a hard bristle part;

[0008] The base part is provided with a base part notch at its front end, so that both sides of the front end of the base part have front convex parts, and the front convex parts have bristles;

[0009] The soft bristle part is provided with an inner concave part along the length direction of the base part so that the height of the soft bristle part in the middle position is lower than the height of the two sides;

[0010] The hard bristle part is located at the periphery of the soft bristle part, and the height of the hard bristle part is lower than the height of the side edge of the soft bristle part.

[0011] The inventive concept of the present invention is: on the basis of Chinese patent document CN 219894963 U, the hard bristle part is changed to the periphery of the soft bristle part. Since the height of the hard bristle part is lower than the height of the side of the soft bristle part, when the base part presses the outer facade or top surface of the tooth nearly in parallel, the soft bristle part bends outwards on both sides respectively, and the probability of the hard bristle part directly contacting the tooth surface is not high, which is beneficial to protecting the teeth or gums. Secondly, when the soft bristle part bends outwards on both sides respectively, due to the support of the hard bristle part, part of the pressure can be shared, and the soft bristle part is not easy to fall over excessively. When it is necessary to clean the connection between the dental brace and the teeth, the brush head can be turned sideways so that the hard bristle part directly contacts the dental brace or teeth, which is convenient for brushing away food residues stuck therein.

[0012] On the other hand, the brush head described in Chinese patent document CN 219894963 U has only short bristles at the front end, which requires the user to push it hard into the oral cavity to clean the wisdom teeth, which can easily cause discomfort to the user. Secondly, its structure is not easy to clean the inner surface of the teeth. However, since the front convex part of the front end of the base part is provided with bristles, it can conveniently and flexibly clean the wisdom teeth and the inner surface of the teeth.

[0013] It should be noted that the bristles used in the soft bristle part and the hard bristle part described in the present application are common soft bristles and hard bristles on the market. Generally speaking, if the bristles are placed on the fingertips and are not easy to fall down and feel stinging when lightly pressed, they are hard bristles.

[0014] As a preferred solution, the front end of the base is concave or V-shaped, so that two front convex parts with bristles are formed at the front end of the base.

[0015] As a preferred solution, the soft bristle portion has a concave or V-shaped top to accommodate a dental brace protruding from the tooth surface.

[0016] As a further preferred solution, the height of the hard bristle portion is 1 / 2-2 / 3 of the height of the side of the soft bristle portion.

[0017] As a preferred solution, the base part has a connection end for connecting to a brush handle, and the brush handle is connected to the brush head by threading or plugging.

[0018] As a further preferred solution, the brush handle is provided with an extrusion slit for pushing the toothpaste forward from the rear end of the toothpaste box, and the cross section of the extrusion slit is truncated cone-shaped.

[0019] In summary, the utility model is suitable for comprehensive cleaning of teeth and dental braces by changing the setting positions of the soft bristle part and the hard bristle part, limiting the length of the hard bristle part, and changing the front end of the base part. In addition, compared with the prior art, the probability of the soft bristle part falling over is reduced. BRIEF DESCRIPTION OF THE DRAWINGS
