After the size is adjusted, format conversion is performed on the image with the preset size, wherein different formats of the environment image in the water outlet range of the acquired shower head may be caused due to different sampling formats of the camera devices, for example, YUA format or RGB format may be possible, and format conversion is performed on the environment image with the preset size by using a conversion formula to convert the environment image into a uniform format, for example, the environment image with the preset size is unified into RGB format. The method is convenient for the human body part recognition model to process the environment image and improves the recognition accuracy.

And S103, acquiring target water outlet parameters matched with the description information of the current human body part, and controlling the shower head to spray water according to the target water outlet parameters.
The description information of the human body part and the water outlet parameters of the shower head have a corresponding relation, and the corresponding relation can be flexibly set by a user. In general, the description information of the human body part is different, and the water outlet parameters of the shower head are also different, wherein the water outlet parameters comprise the water temperature, the water quantity, the gear, the water pressure and/or the water speed of the outlet water. For example, the head is corresponding to a higher water temperature, a slower water speed and a larger water volume, and the four limbs of the human body are suitable for a lower water temperature, a faster water speed and a smaller water volume. The shower head is controlled to discharge water according to the target water discharge parameter, so that the water discharge parameter of the shower head is matched with the current bathing part of the user, and the bathing comfort of the user can be greatly improved.
In one embodiment, a mapping relation table between preset effluent parameters and description information of human body parts is obtained; and determining a target water outlet parameter matched with the description information of the current human body part according to the mapping relation table. The mapping relation between the water outlet parameters and the description information of the human body part can be set according to actual conditions, and the embodiment of the application is not particularly limited. According to the mapping relation table and the description information of the current human body part, the target water outlet parameters can be determined quickly and accurately.

It should be noted that, due to the difference in gender and age, the water outlet parameters suitable for different body parts of different users are different. For example, the body temperature of women is generally higher than that of men, so the water temperature suitable for each body part of women is generally slightly higher than that of men, and as the age of people becomes higher, metabolism becomes slower, the body temperature also increases with the age, so the water temperature suitable for each body part of old people is also basically slightly higher than that of young people. According to the user information and the description information of the current human body part, the matched target water outlet parameter is determined, the water outlet parameter of the shower head can be intelligently controlled, so that water flow suitable for the current bathing part and the user information of a user is output, and the bathing comfort of the user is greatly improved.

Illustratively, a face image in a water outlet range (such as a visible range of a camera) of the shower head is acquired through a shooting device, the face image is sent to a processor of the water heater, then the face image is subjected to face recognition through a face recognition model preset in a memory, a recognition result is obtained, the recognition result can comprise characteristic information or identification information of a user, and the like, for example, the recognition result comprises face information of the user, or comprises a hair style, a face shape, whether glasses are worn, and the like, and user information of the user who uses the shower head at present can be determined based on the recognition result.
In one embodiment, the method for controlling the water outlet of the shower head according to the target water outlet parameter comprises the following steps: determining the adjusting parameters of the water heater according to the target water outlet parameters; and controlling the water heater to operate based on the adjusting parameters, so that the shower head outputs water flow of the target water outlet parameters along with the operation of the water heater.

Cold water is conveyed to the water outlet valve through the cold water inlet, and hot water is conveyed to the water outlet valve through the hot water inlet; the water outlet is connected to the water outlet pipe, and the water outlet valve mixes the conveyed cold water and hot water through the water outlet pipe and conveys the mixed water flow to the shower head so that the shower head sprays water. The water outlet valve also comprises a movable switch, and the water outlet quantity, the water outlet pressure and/or the water outlet temperature of the shower head can be controlled through the movable switch of the water outlet valve. For example, the water heater controls the deviation of the movable switch of the water outlet valve to a cold water inlet or a hot water inlet through the motor so as to control the water outlet temperature of the shower head, and the water heater controls the water outlet quantity and/or the water outlet pressure of the shower head through the lifting angle of the movable switch of the water outlet valve controlled by the motor.
It should be noted that the adjustment parameter of the outlet valve of the water heater may be determined according to a target outlet parameter, for example, a target offset angle at which the outlet valve is offset to the cold water inlet or the hot water inlet, or a target raising angle of the movable switch, the adjustment parameter of the motor may be determined according to the target offset angle or the target raising angle, and the motor is controlled to operate based on the adjustment parameter of the motor, so that the offset angle of the outlet valve reaches the target offset angle, or the raising angle of the movable switch reaches the target raising angle, so that the shower head outputs a water flow of the target outlet parameter along with the operation of the motor, thereby greatly improving the comfort level of bathing of a user.

The through hole regulator comprises a motor, a water distribution disc and an impeller, the impeller is rotatably connected with the water distribution disc and shields the through hole of the shower head through rotation, and the motor is used for driving the impeller to rotate in the water distribution disc. For example, the shower head includes a plurality of types of through holes having different diameters, and the through hole regulator can be used to regulate the type of through hole opened by the shower head, thereby regulating the water yield and/or water pressure of the shower head. Specifically, determining the target type of the through hole corresponding to the target water outlet parameter so as to determine the target position of the impeller to be rotated; the control impeller rotates to the target position, so that the shower head switches to open the through hole of the target type, the adjustment of the water outlet gear of the shower head is completed, and the shower head discharges water according to target water outlet parameters.
