Description

Technical Field

[0001] The utility model relates to the field of small household appliances, in particular to a swing-type toothbrush head and a toothbrush. Background Art

[0002] The existing electric toothbrush head structure usually uses the toothbrush handle as the main bristle planting body. During the cleaning process, the power output shaft in the handle assembly drives the toothbrush handle, and the rotation of the toothbrush handle drives the bristles to swing to achieve the purpose of cleaning teeth. This structure has the following problems:

[0003] First, the efficiency is low. The mass of the bristles and bristle implants used for cleaning accounts for about 30% of the mass of the electric toothbrush head assembly, while the mass of the toothbrush handle assembly, which does not have a cleaning function, accounts for about 70%. During the cleaning process, the toothbrush handle assembly and the bristle implant assembly simultaneously swing under the rotation of the drive shaft. The wasted work exceeds the total work of the drive shaft, so the efficiency is not high.

[0004] Second, the user experience is poor. To improve cleaning effectiveness, existing electric toothbrushes typically use a large-amplitude, high-frequency drive scheme. This drive scheme forces users to endure the discomfort of the large swinging of the toothbrush handle in their mouths in order to achieve a good cleaning effect.

[0005] Therefore, it is necessary to provide a toothbrush head with high cleaning efficiency and good user experience. Utility Model Content

[0039] See also Figure 1 The swing-type toothbrush head shown includes a bristle implant 3, a rotating shaft 2, and a toothbrush handle 1. The toothbrush handle 1 is sleeved on the outside of the rotating shaft 2, and the rotating shaft 2 can rotate relative to the toothbrush handle 1. The bristle implant 3 is located at one end of the toothbrush handle 1 and is connected to one end of the rotating shaft 2. The rotating shaft 2 can drive the bristle implant 3 to rotate relative to the toothbrush handle 1. Thus, by separately assembling the bristle implant 3 from the toothbrush handle 1, the rotating shaft 2 directly drives the bristle implant 3 to swing while the toothbrush handle 1 remains stationary.

[0040] For details, please refer to Figure 2-5In this embodiment, the toothbrush handle 1 includes a protective cap 102 on the top and a connecting end 103 at the bottom. The bristle body 3 is installed inside the protective cap 102, and a mounting groove 101 is provided on the side of the protective cap 102. The bristle body 3 includes a bristle end on the front side and a clip-on end on the rear side. The bristle end is arranged in the mounting groove 101, and a plurality of bristle holes are provided on the bristle end. The bristles 301 are provided in the bristle holes, and the bristles 301 extend to the outside of the toothbrush handle 1 through the mounting groove 101. A through hole 104 communicating with the inside of the protective cap 102 is provided in the connecting end 103 of the toothbrush handle 1. The rotating shaft 2 is passed through the through hole 104 and extends to the protective cap 102 to be connected with the clip-on end of the bristle body 3. The rotating shaft 2 can drive the bristle body 3 to rotate, thereby driving the bristle end of the bristle body 3 to swing in the mounting groove 101.

[0041] Specifically, the toothbrush handle 1 is further provided with a cleaning port 105, which is located on the other side of the protective cap 102 opposite to the mounting groove 101, and is in communication with the interior of the protective cap 102. When rinsing the toothbrush head with water, more water can flow through the movable gap between the bristle implant and the toothbrush handle 1 through the clean water port, making it easier for the user to rinse the toothpaste foam on the toothbrush head.

[0042] Specifically, a bayonet 302 is provided at the bottom of the clamping end of the bristle implant 3 , and one end of the rotating shaft 2 is installed in the bayonet 302 and connected to the bristle implant 3 through the bayonet 302 .

[0043] Preferably, in this embodiment, the rotating shaft 2 is a D-shaped shaft, and correspondingly, the bayonet 302 is a D-shaped bayonet corresponding to the D-shaped shaft. A limit member 303 facing the rotating shaft 2 is provided in the D-shaped bayonet, and a limit groove 201 matching the limit member 303 is correspondingly provided on the rotating shaft 2, and the limit member 303 is snapped into the limit groove 201. The limit member 303 is an elastic triangular protrusion that cooperates with the limit groove 201 on the drive shaft and serves as a limit member for inserting or removing the rotating shaft 2 from the bayonet 302, which can effectively prevent the hair implant 3 from being separated from the rotating shaft 2 during operation.

[0044] Specifically, a convex shaft 304 is provided at the bottom of the hair implant 3, and a flat gasket 4 is provided at the bottom of the convex shaft 304. The convex shaft 304 abuts against the top of the connecting end 103 through the flat gasket 4, thereby reducing movement friction resistance.

[0045] Specifically, a fixed shaft 5 is provided on the top of the protective cap 102, and the fixed shaft 5 corresponds to the axis of the rotating shaft 2. A small hole-type drive shaft hole matching the fixed shaft 5 is provided on the top of the hair implant 3. The fixed shaft 5 is arranged inside the small hole-type drive shaft hole. The fixed shaft 5 and the small hole-type drive shaft hole form a clearance fit. The hair implant 3 can rotate around the fixed shaft 5 and serve as the upper rotating shaft of the hair implant.

[0046] Specifically, it also includes a color ring mark 6. An open groove is provided on the outer side of the bottom of the connecting end 103 of the toothbrush handle 1. The color ring mark 6 is installed in the bayonet 302 groove. Color rings of different colors are equipped to enable users to easily identify their own or their family's toothbrush heads, avoiding family members from mixing toothbrush heads for brushing their teeth.

[0047] This embodiment also provides a toothbrush, including a handle assembly 7 and the above-mentioned oscillating toothbrush head, and the oscillating toothbrush head is installed on the handle assembly 7.

[0048] Specifically, in this embodiment, the toothbrush handle 1 and the handle assembly 7 are locked with each other using special-shaped convex and concave structures that match each other. When the rotating shaft 2 is working, the toothbrush handle 1 will not move with the rotation of the rotating shaft 2.

[0049] Preferably, in some embodiments, a plurality of cleaning ports 105 are provided.

[0050] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and such modifications or substitutions should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
