[0033] This embodiment 1 provides an electric toothbrush head.

Referring to FIGS. 1 and 2, the electric brush head includes a head main body 1 and a plurality of tufts of bristles 2. The bristles 2 are fixedly mounted on the head main body 1, and in order to better express the structure of the vibrating body, Figs. 1 and 2 only exemplarily show several clusters of bristles 2 therein.

Further, the head main body 1 is further provided with at least one vibrating body 3 for moving with the head main body 1, and the vibrating body 3 is convexly disposed between the bristles 2, and the vibrating body 3 has a convex height lower than the bristles 2.

[0036] wherein the head main body 1 and the vibrating body 3 can be separately manufactured and then assembled together.

[0037] The number of the vibrating bodies 3 can be flexibly selected according to actual needs. Referring to FIG. 2, the first embodiment 1 is described by taking two vibrating bodies 3 as an example.

[0038] The vibrating body 3 is preferably disposed at an intermediate position of the plurality of tufts 2 so as to better allow the liquid to flow quickly, to rinse the teeth, and to handle the bristles 2.

[0039] With continued reference to FIG. 2, in the present embodiment, the two vibrating bodies 3 are located in the middle of the longitudinal two tufts of bristles 2

. Since FIG. 2 omits the drawing of part of the bristles, FIG. 2 only draws the bristles of the vibrating body 3 - side

2.

[0040] In this example, the convex direction of the vibrating body 3 is in the same direction as the convex direction of the bristles 2, and the height of the vibrating body 3 is lower than that of the bristles 2, in order to cause the amplitude of the bristles 2 to be reduced on the teeth, It is ensured that the vibrating body 3 can be pressed against the teeth to maintain a large amplitude vibration, so that the liquid is swept by the outer wall of the vibrating body 3, so that the brushing liquid flows quickly, and the debris remaining in the bristles 2 is flushed while the teeth are being washed. Go out.

[0041] The vibrating body 3 vibrates, and the outer wall itself taps the liquid to accelerate the flow of the liquid. Of course, the outer wall of the vibrating body 3 can also be consciously arranged for tapping the liquid during the vibration to cause it to flow in a certain direction. Guide surface.

[0042] The guiding surface may be a flat surface, a bevel surface, a curved surface, a concave surface, a convex surface, a undulating surface and the like on the vibrating body 3, and the like, which can be used for tapping the brushing liquid, causing the liquid to rapidly flow in a certain direction.

[0043] Of course, the arrangement of the shape and angle of the guiding surface affects the direction in which the liquid flows after being beaten, and can be flexibly selected by those skilled in the art as needed. The present embodiment selectively employs a guide surface which is obliquely disposed on the outer wall of the vibrating body 3, so that the liquid is beaten to have an oblique flow direction for better washing of the teeth and the bristles 2.

[0044] Specifically, as shown in FIG. 3, the guiding surface of the embodiment is a slot wall of the obliquely disposed groove 31, and the groove 31 may also be disposed as two, and the two grooves 31 are back. To set, tap the liquid from both directions.

[0045] Obviously, in other embodiments, any one of the guiding faces, such as one, three, four, or the like, may be disposed on the outer wall of the vibrating body 3.

[0046] Further, the material of the vibrating body 3 may be selected from a flexible material or a non-flexible material. The exemplary structure of this embodiment is made of a flexible one, which ensures that even if the force is excessively applied during brushing, the vibrating body 3 is touched to the teeth without causing discomfort to the user.

[0047] When the vibrating body is made of a flexible material, the natural vibration frequency of the vibrating body can be matched with the vibration frequency of the electric brush head. Here, the correspondence refers to a resonance or resonance between the vibrating body and the electric brush head.

, in order to obtain a larger amplitude.

[0048] Further, in order to make the vibrating body have a better vibration effect, the cross section of the vibrating body in a direction perpendicular to the convex direction thereof may be a flat elongated shape, and the longer side of the flat elongated shape and the electric toothbrush head may be The swinging direction forms an acute or right angle structure.

[0049] The term "flat shape" as used herein includes various shapes such as a rectangular shape, an elliptical shape, a waist shape, and a flat shape.

[0050] For example, as shown in FIG. 2, the direction of the arrow in the figure is the swinging direction of the electric brush head. In the embodiment, the cross section of the vibrating body in the direction perpendicular to the convex direction is a waist shape, and the waist shape is compared. The long side forms a right angle structure with the direction of oscillation of the electric brush head.

[0051] In summary, the electric toothbrush head provided in this embodiment is used to brush the gums. When the bristles 2 press the teeth, the vibrating body 3 can still vibrate with the head body 1, and the vibrating body 3 is in the process of vibration. The guiding surface on the bristles will pat the liquid in the bristles 2, allowing it to flow quickly, flushing the teeth without generating a flow cleaning force, and also quickly flushing the debris from the teeth out of the bristles 2, preventing debris from remaining in the bristles. 2 in. Example 2:
