Description

Technical Field

[0001] This invention relates to the technical field of oral cleaning tools, and in particular to a cleaning brush head specifically designed for cleaning the side of missing teeth. Background Technology

[0002] Tooth loss and gingival recession are common oral diseases. Patients with these conditions are prone to developing deep undercuts on the proximal surfaces and necks of remaining teeth due to tooth loss and periodontal tissue atrophy. This is often accompanied by clinical crown elongation, root exposure, and increased interdental spaces. In daily oral hygiene, the common flat brush head design struggles to effectively clean the interdental spaces and lacks the ability to specifically clean the undercuts on the proximal surfaces of remaining teeth. This leads to inadequate cleaning in these areas, resulting in plaque buildup and increasing the incidence of dental caries, periodontal disease, and other oral diseases.

[0003] In addition to the common flat or disc-shaped brush head designs, existing technologies also include tapered interdental brushes for cleaning between teeth. However, their brush heads are often small and difficult to conform fully to the tooth surface, making them less convenient to use than interdental cleaning tools such as dental floss and toothpicks. Therefore, for patients with missing teeth, current oral hygiene tools on the market are still insufficient to meet the needs of cleaning the undercut areas on the adjacent surfaces of remaining teeth. Although electric toothbrushes have been proven to be more efficient than manual toothbrushes, the similar flat-head design has not yet solved the problem of effective cleaning of the special undercut areas of patients with missing teeth.

[0004] In terms of gum massage techniques, specialized tools such as tapered rubber tip massagers exist, which use rotation, light pressure, and picking motions to massage the periodontal tissues, promote gingival blood circulation, and enhance epithelial keratinization. However, for patients with missing teeth, the tapered massage head design makes point massage of extensive edentulous areas cumbersome and time-consuming. Furthermore, the individual massage steps increase the time spent on each oral cleaning session, reducing the patient's willingness to clean themselves. Summary of the Invention

[0005] To address the challenges of cleaning and facilitating the use of brushes on the proximal surfaces of remaining teeth and the deep undercut areas at the neck in patients with missing teeth, this invention provides a dedicated cleaning brush head for the side of missing teeth.

[0006] The present invention provides a special cleaning brush head for the side of missing teeth, which adopts the following technical solution:

[0007] A cleaning brush head specifically designed for cleaning the side of dentition gaps, comprising:

[0008] The housing is used to engage with the vibration source drive of the brush handle and to drive the brush shaft to vibrate;

[0009] The brush shaft is rotatably mounted on the outer casing.

[0010] bristles arranged on the brush shaft along the length direction of the brush shaft;

[0011] a driving member arranged in the housing in driving cooperation and used for driving the brush shaft to rotate.

[0012] Optionally, the bristles are divided into a flat area and an expansion area along the length direction of the brush shaft, the bristles in the flat area have the same length, the bristles in the expansion area have lengths increasing in sequence from the end close to the housing to the end away from the housing, the bristles in the expansion area and the bristles in the transition area are used for being fitted to the shape of the proximal surface of the natural tooth, and the bristles away from the driving member form a small angle with the brush shaft to avoid forming excessive pressure on the gums by the brush shaft.

[0013] Optionally, a buffer layer is fixedly arranged at the end of the brush shaft away from the housing, and the buffer layer is used for contacting the gums in the gap area.

[0014] Optionally, a connecting piece is arranged in rotational cooperation at the end of the brush shaft away from the housing, and the buffer layer is fixedly arranged at the end of the connecting piece away from the housing.

[0015] Optionally, a driving mechanism for driving the connecting piece to rotate is arranged on the brush shaft, the driving mechanism comprises a driving gear, a fixed rod and a plurality of driven gears, the plurality of driven gears are in mesh with the driving gear, the fixed rod is coaxially arranged between the driven gears and the connecting piece, and the driving gear is arranged in driving cooperation on the brush shaft and used for driving the connecting piece to rotate.

[0016] In summary, the present application has at least one of the following beneficial technical effects:

[0017] 1. The special brush head design combines cleaning and massage to achieve double effects. In terms of cleaning performance, the small and flexible brush head can enter the gap and is more fitted to the shape of the patient's own teeth, so that more comprehensive cleaning can be achieved.

[0018] 2. While cleaning, the bristles at the top can massage the gums in the gap area, promote blood circulation and epithelial keratinization, and alleviate the condition of gum atrophy of the patient.

[0019] 3. The cleaning and massage functions are integrated in one brush head, so that the patient does not need to replace the brush head or perform complex hand operations, the use is convenient, the operation difficulty of the brush head is small, the frequency of oral cleaning of the patient is ensured to a certain extent, and the use enthusiasm of the patient is improved.

[0024] The following will be described in detail below with reference to the accompanying drawings Figures 1-3 The present application will be further described in detail.

[0025] An embodiment of the present application discloses a special cleaning brush head for the side of a dental arch gap.

[0026] Referring to Figure 1 , Figure 2 , Figure 3 A special cleaning brush head for the side of a dental arch gap, the brush head comprising a shell 1, a brush shaft 2, bristles 3 and a driving member 4, the shell 1 is connected with a vibration source of a brush handle for driving the brush shaft 2 to vibrate, the brush shaft 2 is rotationally fitted on the shell 1, the bristles 3 are arrayed on the brush shaft 2, and the driving member 4 is installed in the shell 1 for driving the brush shaft 2 to rotate.

[0027] The shell 1 adopts a cylindrical shell body without edges and corners, which will not scratch the oral cavity during use. The inside of the shell 1 is hollow, the driving member 4 is installed in the shell 1, the driving member 4 adopts a rotary motor, the output shaft of the rotary motor is coaxially fixedly connected with the brush shaft 2 through a shaft coupling, thereby driving the brush shaft 2 to rotate.

[0028] The shell 1 is installed on the brush handle through plug-in or rotary buckle type connecting devices. In this embodiment, a connecting groove is formed in the bottom of the shell 1, a vibration motor is built in the brush handle, a vibration rod is installed on the vibration motor, and the vibration motor and the vibration rod constitute a vibration source. The vibration rod is connected with the connecting groove, thereby transmitting the vibration generated by the vibration motor to the shell 1.

[0029] The bristles 3 are divided into a flat area 31 and an expanded area 32 along the length direction of the brush shaft 2, the flat area 31 is closer to the shell 1 than the expanded area 32. The bristles 3 in the flat area 31 have the same length, the length of the bristles 3 in the expanded area 32 increases from the end close to the shell 1 to the end away from the shell 1, and the bristles 3 in the expanded area 32 and the bristles 3 in the transition area are used to fit the shape of the proximal surface of the natural teeth. The bristles 3 with the flat area 31 and the expanded area 32 can flexibly enter the gap and fit the shape of the patient's own teeth in appearance, so that more comprehensive cleaning can be achieved. The bristles 3 in the expanded area can tightly wrap or cover the undercut area of the tooth, and can clean the proximal undercut area and exposed root surface of the teeth on both sides of the gap during use. For patients with a larger undercut area, the lateral pressing force of the brush head can be adjusted by pressing the handle, thereby increasing the wrapping area of the bristles 3 on the teeth and improving the cleaning effect.

[0030] After the brush head is installed on the brush handle, it has two working modes, one is a vibration mode and the other is a rotation mode; the vibration mode is to start only the vibration motor, and the vibration generated by the vibration motor is transmitted to the brush shaft 2 through the shell 1, so that the bristles 3 on the brush shaft 2 vibrate at high frequency; the rotation mode is to start only the driving member 4, and the driving member 4 drives the brush shaft 2 to rotate, so that the bristles 3 rotate around the axial direction of the brush shaft 2; after one of the two working modes is turned on, the brush head is placed near the gap, the position of the brush head is adjusted to tightly fit the tooth surface that needs to be cleaned, and the pressing force is controlled to clean the undercut area and the root surface exposed after the gum atrophy.

[0031] The end of the brush shaft 2 away from the shell 1 is fixedly provided with a buffer layer 5, and the buffer layer 5 is used to contact the gum in the gap area.
