Problems solved by technology

[0002] Currently on the market, the main pressure detection solution for electric toothbrushes currently on the market is to attach strain gauges (piezoelectric, piezoresistive) to the motor shaft of the electric toothbrush, and then apply force to the piezoelectric, piezoresistive, The micro-deformation produced by other materials to detect the force on the toothbrush head, or realize the toothbrush pressure detection system through the Hall sensor, and realize the toothbrush pressure detection system through the motor current, so the pressure detection system of most toothbrushes requires additional pressure detection. System to achieve, to a certain extent, increase the cost of electric toothbrush

Embodiment 1

[0055] figure 1 It is a schematic structural diagram of an electric toothbrush used in an electric toothbrush pressure detection method provided in Embodiment 1 of the present invention, figure 2 It is a flow chart of an electric toothbrush pressure detection method provided in Embodiment 1 of the present invention. The electric toothbrush pressure detection method is used for electric toothbrushes, such as figure 1 As shown, the electric toothbrush includes a toothbrush main body 1 and a vibration detection part ( figure 1 not shown in), the vibration detection part is used to detect the vibration information of the toothbrush main body 1; the toothbrush main body 1 may include a brush head 11, and this embodiment is applicable to the situation of detecting the pressure of the brush head 11, and the method may be composed of electric toothbrush to perform, such as figure 2 As shown, the electric toothbrush pressure detection method specifically includes the following step...

Embodiment 2

[0064] image 3 It is a flow chart of a method for detecting pressure of an electric toothbrush provided by Embodiment 2 of the present invention. This embodiment of the present invention is optimized on the basis of the foregoing Embodiment 1. Optionally, the correspondence between vibration information and pressure information includes a correspondence between vibration quantization signals and pressure information. Based on this, if image 3 As shown, the electric toothbrush pressure detection method specifically includes the following steps:

[0065] S210. Acquire real-time vibration information detected by the vibration detection component.

[0066] S220. Determine real-time vibration quantification information based on the real-time vibration information.

[0067] Among them, quantization refers to the process of approximating continuous values ​​(or a large number of possible discrete values) of a signal to a finite number or fewer discrete values. The real-time vib...

Embodiment 3

[0091] Figure 4 It is a flow chart of a pressure detection method for an electric toothbrush provided by Embodiment 3 of the present invention, which is optimized on the basis of Embodiment 1 above. Such as Figure 4 As shown, the electric toothbrush pressure detection method specifically includes the following steps:

[0092] S310. Establish a corresponding relationship between vibration information and pressure information.

[0093] Among them, different types of electric toothbrushes have different correlations between vibration information and pressure information. By establishing the corresponding relationship between vibration information and pressure information in advance, the pressure detection requirements of different types of electric toothbrushes can be matched, and the versatility is strong.

[0094] S320. Acquire real-time vibration information detected by the vibration detection component.

[0095] S330. Determine current pressure information based on the c...

Abstract

The invention discloses an electric toothbrush pressure detection method and an electric toothbrush. The electric toothbrush pressure detection method is used for the electric toothbrush, the electric toothbrush comprises a toothbrush body and a vibration detection piece, and the vibration detection piece is used for detecting vibration information of the toothbrush body; the electric toothbrush pressure detection method comprises the following steps: acquiring real-time vibration information detected by the vibration detection piece; and determining current pressure information based on the corresponding relationship between the vibration information and the pressure information and the real-time vibration information. By adopting the scheme, the pressure detection of the electric toothbrush does not need an additional pressure detection system so as to reduce the pressure detection cost of the electric toothbrush.
