In this embodiment, if the recognized foreign matter is blood, the water outlet of the water outlet nozzle of the tooth flushing device needs to be controlled according to the blood level and/or the blood concentration, that is, the flushing force and the flushing water amount are adjusted according to the tooth bleeding condition, so as to protect the bleeding area from secondary damage; if the identified foreign matter is not blood, the flushing force and the flushing water quantity are adjusted according to the area of the foreign matter, and the foreign matter is ensured to be quickly flushed away under the condition of not damaging the oral cavity.
The property of the foreign matter includes, but is not limited to, one or more of a foreign matter area, a foreign matter type, a foreign matter thickness.
In one embodiment, controlling the outlet nozzle of the water irrigator to discharge water based on the blood area and/or the blood concentration in the acquired oral cavity image comprises:

s203, carrying out secondary image analysis on the extracted tooth area image, and analyzing and extracting foreign matters in the tooth area;
s204, judging whether the foreign matter is blood, if so, executing S205, otherwise, executing S207;
s205, calculating the area size of blood, the concentration of blood and position coordinates, and quantifying the level of bleeding;
s206, automatically adjusting the flushing force according to the bleeding level, and not flushing at a high level;

and S303, marking the region formed by the recorded points after the step S302 as a non-tooth region, and marking the region formed by the rest points of the image as a tooth region.
The tooth color comprises white, yellow or black. Specifically, if white, it is determined as the tooth color. Because of long-term non-tooth brushing or long-term smoking, the teeth of some people are yellow and black, if the areas of the yellow and black are over a certain preset value (namely, a large area of yellow and black is generated), the yellow or black is judged to be the teeth, and if the areas of the yellow and black are not over a certain preset value, the yellow or black is judged to be foreign matter.

s402, analyzing the processed image, recording all areas with color values of 255, marking the areas as foreign matter areas, and recording corresponding coordinates;
and S403, extracting blood pixel points from the foreign body image, and analyzing and extracting blood or other foreign bodies.
Specifically, as shown in fig. 5, the blood pixel extraction is performed on the foreign object image, and blood is extracted by analysis, including:
s501, traversing all pixel point coordinates of the original image, comparing the coordinates recorded in S402, and if the pixel point is not a recording point, setting the point to be white; only the recording point area on the processed image has color, and the others are white;
s502, converting image information into an hsv format by using opencv, comparing the hsv value of each pixel point with the corresponding value of blood hsv respectively, obtaining a blood part in the range of the hsv value of the blood, and recording corresponding coordinates and the corresponding hsv value;

s504, calculating the average value of the hsv corresponding to the coordinate area, and comparing the average value with the average value of the hsv range value of the blood color, wherein the larger the value is, the thicker the blood is, namely, the blood concentration is higher.
In summary, in this embodiment, if the image is analyzed to be blood, the opencv algorithm is used to calculate the size of the blood area and the blood color depth of the image, and then the area size and the concentration are converted into the low, medium and high levels of the bleeding amount, and the flushing force and the flushing water amount are automatically adjusted according to the low, medium and high levels of the bleeding amount, and the region is not flushed at the high level, so as to prevent the flushed teeth from secondarily damaging the bleeding region.
Specifically, as shown in fig. 6, the blood pixel point of the foreign object image is extracted, and other foreign objects are extracted by analysis, including:

In summary, in this embodiment, if other foreign matters except blood are analyzed, the attribute size of the foreign matters is calculated by opencv, and is also quantized to low, medium and high levels, and then the flushing force and the flushing water amount are automatically matched according to the low, medium and high levels of the foreign matters.
It should be noted that the low, medium, and high levels are only an example, and in specific implementation, more or fewer levels may be set according to needs, and which level corresponds to a large water outflow rate or a large water outflow strength may also be set according to actual needs, which is not specifically limited in this embodiment.
Further, the oral cavity rinsing method of the present embodiment further includes:
after foreign matters (including blood) are washed for a certain time, the foreign matters in the area are analyzed again, if the foreign matters are washed cleanly, the washing is stopped, and if the foreign matters exist, the gear is continuously adjusted to wash.
If after a certain time of rinsing, the foreign body is still present, the analysis may be dental tartar, at which point the rinsing of the teeth in this area is stopped and the user is advised to visit the dentist to preserve oral health.
Further, the embodiment can control the water outlet flow of the water outlet nozzle of the tooth flushing device to be larger, smaller or unchanged based on the blood area and/or the blood concentration in the acquired oral cavity image; and/or controlling the water outlet force of the water outlet nozzle of the tooth flushing device to be larger, smaller or unchanged based on the blood area and/or the blood concentration in the acquired oral cavity image.
Specifically, for the case that the foreign matter is blood, if the foreign matter is judged to be in a high level according to the blood level and/or the blood concentration, the water outlet nozzle of the tooth flushing device is controlled not to perform flushing; if the level is middle, a low-level flushing can be started (for example, the rotating speed of the motor is low, and the flushing time is 1 second); if the level is low, a medium-level flushing (such as 3 seconds of flushing in the motor rotating speed) can be started, on one hand, blood is flushed away, and meanwhile, a bleeding area is protected from secondary damage.
Specifically, when the foreign matter area S is equal to or larger than a judgment threshold Sthl for the case that the foreign matter is non-blood, the water outlet nozzle of the tooth flusher is controlled to flush.
In this embodiment, according to foreign matter area S, the tooth flusher can be divided into three flushing gears, as follows:
when Sthl < S < Sl, the foreign matter area is small, and a low gear is started (the motor speed is low, and the washing lasts for 1 second);
when Sl < S < Sh, the area of foreign matters is medium, and a middle gear is started (the motor rotates at a medium speed and is flushed for 3 seconds);
when S is larger than Sh, the foreign matter area is large, and the high gear is started (the motor is high in rotating speed and is flushed for 5 seconds).
As mentioned above, the specific gear and the specific flushing time can be set according to practical applications, and the embodiment of the present invention is not limited.
In this embodiment, the image acquisition apparatus includes a visible light imaging device, an infrared thermal imaging device, or an ultraviolet imaging device, and may specifically be a bendable camera; the image acquisition device and the tooth flushing device form detachable connection or non-detachable connection.
