In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0037] The electric toothbrush head provided in this embodiment is intended to solve the problem that existing brush heads have poor ability to remove exogenous stains on teeth. The electric toothbrush head can withstand higher contact pressure and contact friction, can provide small-scale micro-friction, can polish the tooth surface, and deeply clean the pores of the enamel honeycomb structure, thereby improving the removal effect of exogenous stains.

[0038] like Figures 1 to 9 As shown, the electric toothbrush head includes a bracket 100 and a soft brush head 200. The soft brush head 200 is detachably mounted on the bracket 100. The soft brush head 200 includes an integrally formed column 210 and a spiral structure 220 disposed on the outer peripheral surface of the column 210. The spiral lines of the spiral structure 220 are arranged at an angle to the movement direction of the soft brush head 200. The outer peripheral surface of the soft brush head 200 is provided with a plurality of through holes. Whitening abrasive materials are filled in adjacent spiral lines and / or through holes. Figure 1 and Figure 2 The spacing between adjacent spiral patterns can be set as needed.

[0039] The soft brush head 200 of the electric toothbrush head can be detachably mounted on the bracket 100, which is convenient for disassembly and assembly; the soft brush head 200 includes a column 210 and a spiral structure 220, which are an integrally formed structure. When the soft brush head 200 is in elastic contact with the teeth, it can withstand higher contact pressure and contact friction, and the problem of bristles falling off will not occur; the spiral lines of the spiral structure 220 are set at an angle to the movement direction of the soft brush head 200, and the spiral lines are used to generate pulse impact friction. Under the pulse impact friction, the adhesion of the deposits on the tooth surface gradually decreases until they fall off from the tooth surface, thereby improving the friction cleaning ability. Fig.10 and Fig.11 , Fig.10 The middle spiral pattern is parallel to the movement direction of the soft brush head 200. Under the action of the thrust F, the amplitude of the distance of the boundary line pushed by the thrust F is A1; Fig.11The middle spiral纹路is arranged at an angle to the movement direction of the soft brush head 200. Under the action of the thrust F, a component force, namely the cutter component force F1, is generated in the direction of the spiral纹路, and at the same time, a frictional component force f is also generated. At this time, the amplitude of the movement distance of the boundary line pushed by the thrust F is A2. When the spiral纹路friction with the teeth, the thrust F is used to friction the impurities such as tooth surface stains. Under the same resistance, compared with the parallelogram structure, the rectangular structure has a shorter movable distance. Because the frictional resistance along the direction of the spiral纹路is the smallest, the thrust F makes the movement distance of the boundary line A2 as the amplitude, A1 < A2. According to the area formulas of the rectangular structure and the parallelogram, it can be known that Figure 7 the area of the parallelogram in Figure 6 is larger than the area of the rectangular structure in

[0040] That is, through the spiral纹路, the friction area can be effectively increased, thereby improving the friction effect, similar to shoveling snow, and it is easier to use the oblique shoveling force.

[0041] Optionally, the spiral纹路is arranged unidirectionally. Preferably, the spiral纹路is arranged in a two-way cross pattern. Under the same friction area, the two-way cross threads can generate more oblique lines and angles, which can effectively improve the cleaning effect on exogenous stains.

[0042] In some possible implementation manners, the material of the soft brush head 200 includes a color-developing part, and the color-developing part is used to indicate the component characteristics of the detachment on the tooth surface. Sufficient color development can target specific substances for color development, which can include pH or microbial characteristic identification, etc. Optionally, the soft brush head 200 can be set to a soft glue material.

[0043] In this embodiment, the whitening abrasive material includes an oxidant to bleach the stains through an oxidation reaction; and / or, the whitening abrasive material includes an acidic or alkaline pH characteristic material to perform a chemical reaction bleach on the stains. The whitening abrasive material can include at least one of a consumable material, an abrasive material, and a whitening material. For example, the whitening abrasive material is a daily chemical gel, a powder material, or a liquid material.

[0044] Preferably, a plurality of isolation protrusions 230 are convexly disposed on the outer peripheral surface of the cylinder 210, and the extension direction of the isolation protrusions 230 is parallel to the axial direction of the cylinder 210, and the height of the isolation protrusions 230 is greater than the height of the spiral lines. The isolation protrusions 230 form isolation walls to protect the whitening abrasives, reduce the overflow of the whitening abrasives, and prevent the whitening abrasives from leaving the tooth surface during brushing, so as to improve the utilization rate and uniformity of the whitening abrasives.

[0045] In some possible embodiments, the bracket 100 is provided with a receiving cavity, and a light-emitting component, a heating component, a cooling component or an electromagnetic wave generating component is installed in the receiving cavity. When the light-emitting component is installed, the bracket 100 and the soft brush head 200 are made of light-transmitting materials, and the light emitted by the light-emitting component is transmitted to the tooth surface via the bracket 100 and the soft brush head 200. Alternatively, when the light-emitting component is installed, the bracket 100 is set to a light-transmitting material, and a light-transmitting hole is set on the soft brush head 200, and the light emitted by the light-emitting component is transmitted to the tooth surface via the bracket 100 and the light-transmitting hole. When the whitening abrasive material contacts the teeth, the provision of the light-emitting component, the heating component, the cooling component or the electromagnetic wave generating component can assist in stimulating the catalytic reaction between the whitening abrasive material and the exogenous stains of the teeth, thereby improving the whitening efficiency.

[0046] Optionally, a pressure sensor is installed on the bracket 100, and the pressure sensor is used to obtain the pressure value of the soft brush head 200 acting on the tooth surface; and / or, an image acquisition sensor is installed on the bracket 100, and the image acquisition sensor is used to acquire an image of the tooth surface.

[0047] See also Figure 7 and Figure 8 Optionally, the bracket 100 includes a guide column 110 and a plug-in rod 120 installed on the guide column 110, the column 210 is provided with a plug-in hole 211 that cooperates with the plug-in rod 120, and the guide column 110 is connected to the driving member. During assembly, the column 210 is sleeved on the plug-in rod 120, and the plug-in rod 120 is inserted into the plug-in hole 211, so as to achieve a close combination of the soft brush head 200 and the bracket 100, so that the soft brush head 200 moves with the bracket 100. Optionally, the plug-in rod 120 is set to a prismatic structure, and this setting can improve the fixed binding force between the two when the plug-in rod 120 rotates to drive the column 210 to move. In actual implementation, the prismatic structure can be a pentagonal prism structure or a hexagonal prism structure, which can be set as needed. In other embodiments, see Figure 7 The longitudinal section of the plug-in rod 120 can be set to be a cross shape.

[0048] As a preference, see Fig. 9The bracket 100 further includes a fixing rod 130 connected to the guide column 110. The fixing rod 130 and the plug-in rod 120 are arranged at intervals. The column 210 is provided with a limiting groove 212 for receiving the fixing rod 130. A clamping space for clamping part of the soft brush head 200 is formed between the fixing rod 130 and the plug-in rod 120. The part of the soft brush head 200 is clamped between the fixing rod 130 and the plug-in rod 120, which can improve the fixing and bonding force of the bracket 100 to the column 210, thereby improving the fixing force between the bracket 100 and the soft brush head 200.

[0049] The electric toothbrush head also includes an electrically connected driving member and a control unit. The bracket 100 is mounted on the output shaft of the driving member. The control unit is used to control the movement speed and movement amplitude of the driving member to adjust the friction effect between the soft brush head 200 and the teeth. Optionally, the driving member is a motor, and the motor shaft of the motor is inserted into the connection hole 111 of the guide column 110 of the bracket 100. The motor shaft drives the soft brush head 200 to rub on the surface of the teeth. The motor can drive the soft brush head 200 to do reciprocating motion or circular motion. The reciprocating motion can be left-right motion or up-and-down motion, or a combination of left-right and up-and-down motion. The circular motion can be clockwise, counterclockwise, or a combination of clockwise and counterclockwise motion.

[0050] Optionally, the soft brush head 200 can be a disposable product. After the soft brush head 200 is installed on the bracket 100, the overall length is less than 6 cm. The existing electric toothbrush head usually bends away from the teeth after being attached to the teeth and subjected to force, so that the drive shaft of the driving member exhibits a conical pendulum motion. At this time, the swing axis is a curve rather than a straight line, which will cause energy consumption and reduce the friction length between the electric toothbrush head and the tooth surface. By setting the overall length to be less than 6 cm, that is, the overall length is significantly shorter than the existing conventional electric toothbrush head length, under the same material and design conditions, it can effectively reduce the curvature of the swing axis, reduce power loss, and increase the friction length of the soft whitening wipe. While shortening the length, it can also increase the rigidity of the bracket 100, increase the supporting force of the electric toothbrush head, and reduce stress deformation.

For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention.
