RELATED APPLICATIONS 
     This application claims priority to Chinese patent application number 202111339131.9, filed on Nov. 12, 2021. Chinese patent application number 202111339131.9 is incorporated herein by reference. 
     FIELD OF THE DISCLOSURE 
     The present disclosure relates to the technical field of outflow water control, and in particular relates to a method for setting calibrated outflow water of a quantitative outflow water faucet, and a method for processing outflow water and a faucet. 
     BACKGROUND OF THE DISCLOSURE 
     At present, quantitative accuracy of a quantitative outflow water faucet mainly depends on calibration of the process equipment in the factory before the product is shipped. After the calibration, the product is shipped, and users can use the product directly after receiving the product but users cannot adjust the quantitative outflow water faucet by themselves when there are inaccuracies. In addition, after the quantitative outflow water faucet is used for a period of time, there may arise inaccuracies (such as differences in flow meters, waterways, valve bodies, etc., which will affect the accuracy to a certain extent. If some parts are replaced when the product is in use, or some waterways change after long-term use, there may be some differences in the quantitative accuracy. In the absence of the calibration, these errors cannot be corrected), so it is necessary to coordinate with professionals of the manufacturer for maintenance or returning the product to the factory for maintenance. The maintenance process is too cumbersome, and the maintenance cycle is long, affecting user satisfaction.

     DETAILED DESCRIPTION OF THE EMBODIMENTS 
     In order to further clarify objectives, technical features, and advantages of the present disclosure, the embodiments of the present disclosure will be further described below in combination with the drawings. 
     Referring to  FIG.  1   , a method for setting calibrated outflow water of a quantitative outflow water faucet of the present disclosure comprises: 
     S 102 : receiving a touch/press signal of an outflow water setting switch, and entering a calibration setting mode; 
     S 104 : receiving a signal for setting one or more quantitative outflow water gear positions of a flow quantity selecting switch, and obtaining a corresponding one of the one or more quantitative outflow water gear positions as a calibrated outflow water gear position; 
     S 106 : receiving a touch/press signal of an outflow water control switch, and controlling an outflow water valve to be opened; when a number of rotations of a flow meter reaches an initial set value of the one or more quantitative outflow water gear positions, controlling the outflow water valve to be closed to obtain an actual outflow water quantity; 
     S 108 : receiving a difference value between a set outflow water quantity of the one or more quantitative outflow water gear positions configured to be input by the user and the actual outflow water quantity; 
     S 110 : setting a calibrated set value of a calibrated outflow water gear position based on the actual outflow water quantity and the difference value; and 
     S 112 : exiting the calibration setting mode. 
     In the method for setting calibrated outflow water of a quantitative outflow water faucet of the embodiment, an execution body may be a control chip of the quantitative outflow water faucet, and a processor is integrated on the control chip. 
     In this embodiment, the calibration setting mode is entered by receiving the touch/press signal of the outflow water setting switch. After the flow quantity selecting switch rotates to one of the one or more quantitative outflow water gear positions, the outflow water valve is controlled to be opened by receiving the touch/press signal of the outflow water control switch. When the number of the rotations of the flow meter reaches the initial set value of the one or more quantitative outflow water gear positions, the outflow water valve is controlled to be closed, an actual outflow water quantity is obtained, and a difference value between the set outflow water quantity of the one or more quantitative outflow water gear positions configured to be input by the user and the actual outflow water quantity is received to perform the calibration to ensure accurate outflow water from the quantitative outflow water faucet and improve user satisfaction. 
     Referring to  FIG.  2   , in another embodiment, before setting the calibrated set value of the calibrated outflow water gear position based on the actual outflow water quantity and the difference value, the method further comprises: 
     S 109 : receiving the touch/press signal of the outflow water setting switch again. 
     Referring to  FIG.  1   , after the calibrated set value of the calibrated outflow water gear position is set based on the actual outflow water quantity and the difference value, the method for setting calibrated outflow water of the present disclosure can exit the calibration setting mode to simplify the operation steps. In order to prevent a false reset, the calibration setting mode can be exited when the touch/press signal of the outflow water setting switch is received again. 
     Specifically, the flow quantity selecting switch comprises a quantitative ring disposed on one side of an outflow water end of the quantitative outflow water faucet, and the quantitative ring comprises a plurality of flow quantity measuring scales. Each of the plurality of flow quantity measuring scales corresponds to one of the one or more quantitative outflow water gear positions. The outflow water end of the quantitative outflow water faucet has an indicator. When the calibration setting mode is not entered and the quantitative ring rotates to enable a scale of the plurality of flow quantity measuring scales to be aligned with the indicator, the set outflow water quantity that is currently selected is indicated. For example, when the quantitative ring rotates to enable a scale “2” of the plurality of flow quantity measuring scales to be aligned with the indicator, the set outflow water quantity that is currently selected is indicated to be 2 L. When a setting of the one or more quantitative outflow water gear positions is complete, the control chip can calculate the number of required rotations of the flow meter, that is, the initial set value of the one of the one or more quantitative outflow water gear positions. Specifically, according to the factory settings of the flow meter, an outflow water quantity of the flow meter for one rotation of the flow meter is fixed, such as 100 mL, so that the initial set value of the one of the one or more quantitative outflow water gear positions is 20 rotations. However, after a period of use, the quantitative outflow water faucet may be inaccurate, such as the scenario described in the background, and this may cause the outflow water quantity of the one rotation of the flow meter to change. 
     The actual outflow water quantity can be counted by means of an external container or equipment. Specifically, after the outflow water valve is opened, water is received through the external container. After the outflow water valve is closed, a quantity of the water in the external container is measured, and the difference value between the set outflow water quantity of the one or more quantitative outflow water gear positions and the actual outflow water quantity is calculated. Specifically, statistics can be manually performed, or the statistics can be realized through sensors, and the actual outflow water quantity can be fed back to the control chip. 
     It should be noted that, during actual calibration, each of the one or more quantitative outflow water gear positions can be calibrated in turn according to the above setting method to achieve calibration of the quantitative outflow water faucet as a whole. Alternatively, after any one of the one or more quantitative outflow water gear positions is calibrated, the other of the one or more quantitative outflow water gear positions can be calibrated based on an actual outflow water quantity of the one rotation of the flow meter. 
     In an embodiment, the outflow water setting switch and the outflow water control switch are independently arranged. That is, the outflow water setting switch and the outflow water control switch are disposed at different positions of the quantitative outflow water faucet and can be controlled separately at the same time. When the outflow water setting switch and the outflow water control switch are independently arranged, touch/press duration does not need to be considered. As long as there is a touch/press action on the outflow water setting switch or the outflow water control switch, a control command will be triggered. 
     It should be noted that, although the steps in this embodiment include “receiving a touch/press signal of an outflow water setting switch, and entering a calibration setting mode” occurs first, and then “receiving a signal for setting one or more quantitative outflow water gear positions of a flow quantity selecting switch” occurs, in actual implementation, the steps can be reversed such that “receiving a signal for setting one or more quantitative outflow water gear positions of a flow quantity selecting switch” occurs first, and then “receiving a touch/press signal of an outflow water setting switch, and entering a calibration setting mode” occurs. There is no specific limitation in this embodiment. 
     In another embodiment, in order to save costs and simplify the steps, the outflow water setting switch and the outflow water control switch can be set as a same switch, and the processor distinguishes whether the same switch is used for the outflow water setting switch or for the outflow water control switch through different touch/press durations. The specific method is as follows. 
     Before entering the calibration setting mode, the method further comprises: 
     judging a duration of the received touch/press signal of the outflow water setting switch; when the duration is greater than or equal to a first duration, entering the calibration setting mode; 
     before controlling the outflow water valve to be opened, the method further comprises: 
     judging a duration of the received touch/press signal of the outflow water control switch; when the duration is less than a second duration, controlling the outflow water valve to be opened; 
     before exiting the calibration setting mode, the method further comprises: 
     judging the duration of the received touch/press signal of the outflow water setting switch; when the duration is greater than or equal to the first duration, exiting the calibration setting mode; 
     wherein, the first duration is greater than or equal to the second duration. 
     It should be noted that, in other embodiments, the same switch functions as the outflow water setting switch by being pressed for a short duration and functions as the outflow water control switch by being pressed for a long duration (i.e., the long duration is greater than the short duration). The specific methods are as follows. 
     Before entering the calibration setting mode, the method further comprises: 
     judging a duration of the received touch/press signal of the outflow water setting switch; when the duration is less than a second duration, entering the calibration setting mode; 
     before controlling the outflow water valve to be opened, the method further comprises: 
     judging a duration of the received touch/press signal of the outflow water control switch; when the duration is greater than or equal to a first duration, controlling the outflow water valve to be opened; 
     before exiting the calibration setting mode, the method further comprises: 
     judging the duration of the received touch/press signal of the outflow water setting switch; when the duration is less than the second duration, exiting the calibration setting mode; 
     wherein, the first duration is greater than or equal to the second duration. 
     In this embodiment, after receiving the touch/press signal of the outflow water setting switch, the method further comprises: 
     controlling a calibration indicator light to display a first color; 
     after receiving the signal for setting the one or more quantitative outflow water gear positions of the flow quantity selecting switch, the method further comprises: 
     controlling the calibration indicator light to display a second color; 
     after receiving the touch/press signal of the outflow water setting switch again, the method further comprises: 
     controlling the calibration indicator light to display a third color. 
     Specifically, the first color, the second color, and the third color are all different. Alternatively, the first color and the third color are the same, and the second color is different from the first color and the third color. 
     In an embodiment, when the actual outflow water quantity is less than the set outflow water quantity of the one or more quantitative outflow water gear positions, the difference value is positive, and correspondingly, the calibrated set value is greater than the initial set value. When the actual outflow water quantity is greater than the set outflow water quantity of the one or more quantitative outflow water gear positions, the difference value is negative, and correspondingly, the calibrated set value is smaller than the initial set value. 
     The setting the calibrated set value of the calibrated outflow water gear position based on the actual outflow water quantity and the difference value specifically comprises: 
     dividing the actual outflow water quantity by the initial set value of the one or more quantitative outflow water gear positions to obtain an actual outflow water quantity when the flow meter rotates for one rotation; 
     dividing the difference value by the actual outflow water quantity when the flow meter rotates for one rotation to obtain an incremental set value; and 
     adding the initial set value of the one or more quantitative outflow water gear positions to the incremental set value to obtain the calibrated set value, and setting the calibrated set value. 
     Specifically, when the set outflow water quantity of the one or more quantitative outflow water gear positions is 2 L, the initial set value of the one or more quantitative outflow water gear positions is 20 rotations. When the actual outflow water quantity is 2.1 L, the actual outflow water quantity is greater than the set outflow water quantity. At this time, a negative value needs to be input. For example, the difference value that is −0.1 is input, and the control chip will calculate the calibrated set value as (20-(0.1/(2.1/20)) rotations. When the one or more quantitative outflow water gear positions are selected subsequently and after the outflow water valve is controlled to be opened for outflow water, the outflow water valve is controlled to be closed when the number of rotations of the flow meter reaches the calibrated set value. When the set outflow water quantity of the one or more quantitative outflow water gear positions is 2 L and the actual outflow water quantity is 1.8 L, the actual outflow water quantity is less than the set outflow water quantity. At this time, a positive value needs to be input. For example, when the difference value of 0.2 is input, the control chip will calculate the calibrated set value as (20+(0.2/(1.8/20)) rotations. When the one or more quantitative outflow water gear positions are selected subsequently and after the outflow water valve is controlled to be opened for outflow water, the outflow water valve is controlled to be closed when the number of rotations of the flow meter reaches the calibrated set value. 
     Referring to  FIG.  3    to  FIG.  7   , steps for setting calibrated outflow water of an embodiment of the present disclosure comprise: 
     Step 1: long pressing the outflow water setting switch for a T 1  duration (i.e., the first duration) to enable the calibration indicator light to turn red, and a system enters the calibration setting mode; 
     Step 2: rotating the quantitative ring (i.e., the flow quantity selecting switch) to a gear position to be calibrated to enable the calibration indicator light to turn blue; 
     Step 3: short pressing the outflow water control switch for a T 2  duration (i.e., the second duration) to control the outflow water; 
     Step 4: after water quantity sensed by the flow meter reaches the one or more quantitative outflow water gear positions set by the flow quantity selecting switch, controlling the outflow water valve to be closed to obtain the actual outflow water quantity, and judging the difference value between the set outflow water quantity of the one or more quantitative outflow water gear positions and the actual outflow water quantity. When the difference value is not zero, obtaining a difference value to be calibrated (such as touching “+” or “−” in the figure, each touch increases or decreases a corresponding increment, a total adjustment amount is displayed on a display device, referring to “0004” in the figure, a unit of an input value can be mL or L, which can be specifically set as needed); and 
     Step 5: long pressing the outflow water setting switch for the T 1  duration (i.e., the first duration) to enable the calibration indicator light to turn red, and the system exits the calibration setting mode. 
     Referring to  FIG.  8   , a method for calibrating outflow water of the quantitative outflow water faucet, based on the method for setting calibrated outflow water, comprises: 
     S 801 : receiving the one or more quantitative outflow water gear positions set by the flow quantity selecting switch, and judging whether the one or more quantitative outflow water gear positions is the calibrated outflow water gear position; if so, going to S 802 ; otherwise, going to S 803 ; 
     S 802 : after receiving the touch/press signal of the outflow water control switch, and controlling the outflow water valve to be opened. When the number of rotations of the flow meter reaches the calibrated set value, controlling the outflow water valve to be closed; and

     The program control module  905  comprises the outflow water valve  9051 , the flow meter  9052 , and the control chip  9053 . The induction magnet is magnetically connected to a Hall sensor on the control chip  9053 . 
     The control chip  9053  is connected to the outflow water setting switch  901  to receive the touch/press signal of the outflow water setting switch  901  to enter the calibration setting mode, so as to set the one or more quantitative outflow water gear positions selected by the flow quantity selecting switch  903  as the calibrated outflow water gear position. 
     The outflow water control switch  902  is connected to the control chip  9053 . After the calibrated outflow water gear position is selected through the flow quantity selecting switch  903 , the control chip  9053  controls the outflow water valve  9051  to be opened after receiving the touch/press signal of the outflow water control switch  902 . When the number of rotations of the flow meter  9052  reaches the calibrated set value, the control chip  9053  controls the outflow water valve  9051  to be closed. The actual outflow water quantity and the difference value between the set outflow water quantity of the one of the one or more quantitative outflow water gear positions and the actual outflow water quantity are obtained, so that the calibrated outflow water gear position is set based on the actual outflow water quantity and the difference value. The difference value is input through the calibration module  904 . 
     In this embodiment, the outflow water setting switch  901  and the outflow water control switch  902  are set independently. Alternatively, the outflow water setting switch  901  and the outflow water control switch  902  are set as the same switch. 
     Specifically, the outflow water setting switch  901  and the outflow water control switch  902  are touch-sensitive switches or mechanical switches. When the outflow water setting switch  901  and the outflow water control switch  902  are the touch-sensitive switches, the touch-sensitive switches can be triggered by touching, and the touch-sensitive switches can be infrared touch switches, capacitive touch switches, etc. When the outflow water setting switch  901  and the outflow water control switch  902  are mechanical switches, the mechanical switches can be triggered by pressing. 
     In one embodiment, the calibration module  904  comprises a positive difference value setting switch for increasing an outflow water quantity and a negative difference value setting switch for reducing the outflow water quantity. 
     Specifically, the positive difference value setting switch and the negative difference value setting switch are touch-sensitive switches or mechanical switches. When the positive difference value setting switch and the negative difference value setting switch are touch-sensitive switches, the touch-sensitive switches can be triggered by touching, and the touch-sensing switches can be infrared touch switches, capacitive touch switches, etc. When the positive difference value setting switch and the negative difference value setting switch are mechanical switches, the mechanical switches can be triggered by pressing.
