1. A control method of smart toilet having a function of human blood oxygen detection, comprising the following steps:

  • A;

    initiating an initial state of each connected module through a controller;

    B;

    executing self-checking;

    conducting a fault detection on each module through the controller;

    if the self-checking is passed, proceeding to step C;

    otherwise, conducting an exception handling, displaying or reporting exception information through a display or voice prompt module;

    C;

    entering a main cycle,detecting whether someone has sat down by the controller with a human body sensing module;

    if someone has sat down, starting, by the controller, a human blood oxygen detection module to conduct blood oxygen detection;

    obtaining, by the human blood oxygen detection module, an electrical signal related to a human blood oxygen saturation value;

    transferring the electrical signal to the controller;

    after processing, obtaining, by the controller, the human blood oxygen saturation value based on the obtained electrical signal;

    controlling, by the controller, the display or voice prompt module or a communication module communicating to a smart device to output the human blood oxygen saturation value, and proceeding to step D;

    if nobody has sat down, controlling, by the controller, the human blood oxygen detection module to enter dormancy, and proceeding to step D;

    D;

    detecting, by the controller, whether there is an input at a key input module;

    if there is no input, returning to the step C;

    if there is the input, proceeding to step E;

    E;

    performing corresponding operations by the controller based on the input at the key input module;

    setting a temperature of outlet water of cleaning water;

    setting a water pressure of outlet water of cleaning water;

    setting a temperature of drying air;

    starting a user cleaning module to provide the cleaning water or the drying air;

    whereinthe smart toilet includes a toilet base;

    the smart toilet further includes a machine body which is connected to the toilet base;

    the machine body is provided with the controller, the human blood oxygen detection module, the display or voice prompt module, and a power supply module;

    the power supply module is used to supply power;

    the human blood oxygen detection module, the display or voice prompt module, and the power supply module are electrically connected to the controller respectively;

    the human blood oxygen detection module includes two or more LEDs and a power supply control circuit;

    the two or more LEDs release light beams with different wavelengths;

    the power supply control circuit is controlled by the controller and supplies power to the LEDs intermittently;

    the human blood oxygen detection module further includes a photoelectric sensor;

    the photoelectric sensor is electrically connected to the controller;

    wherein the LEDs are provided opposite to the photoelectric sensor, such that after a finger is inserted into a finger hole, the finger is positioned between the LEDs and the photoelectric sensor;

    the photoelectric sensor receives optical signals of the LEDs after the optical signals go through the finger of a human body to be detected;

    the photoelectric sensor converts the optical signals into an electrical signal and transfers the electrical signal to the controller;

    after processing, the controller obtains a human blood oxygen saturation value based on the received electrical signal; and

    the controller controls the display or voice prompt module to output the human blood oxygen saturation value;

    the smart toilet further includes the human body sensing module;

    the human body sensing module is electrically connected to the controller and is used to sense whether the human body has sat down;

    the smart toilet further includes the user cleaning module;

    the user cleaning module is electrically connected to the controller;

    the user cleaning module includes a water spray module, a water pressure control module, a water temperature control module, a fan module, and an air temperature control module;

    the water spray module provides the cleaning water;

    the water pressure control module controls the water pressure of outlet water of the cleaning water;

    the water temperature control module controls the temperature of the outlet water of the cleaning water,the fan module provides the drying air;

    the air temperature control module controls the temperature of the drying air; and

    the water pressure control module, the water temperature control module, the air temperature control module are electrically connected to the controller.
