[0043] Next, the working principle of the embodiment is described in detail to enable those skilled in the art to better understand the present invention:

[0044] The operation process steps of a soft water quality automatic detection and alarm device are as follows:

[0045] S1: Press the automatic detection switch 251 of the device, the device starts, and the timer 23 starts working;

[0046] S2: When the time interval does not reach the set value, the alarm light 221 is always green, indicating that the device is in normal timing operation state;

[0047] S3: When the timer 23 reaches the set value, i.e., the time for soft water detection, the electromagnetic flowmeter 2 on the soft water branch 4 is turned on, the electric valve 3 is opened, the soft water enters the detection container 8, and the alarm light 221 turns green and flashes continuously, indicating that the device is in the state of automatic soft water measurement and detection;

[0048] S4: When the electromagnetic flowmeter 2 detects that the soft water flowing through reaches the set threshold, the electromagnetic flowmeter 2 is closed, and the electric valve 3 is closed. At this time, a certain amount of soft water has been filled in the detection container 8;

[0049] S5: the driving motor 30 is started, driving the coupling 29 to rotate, the coupling 29 drives the cam 28 to rotate, and the connecting rod 27 connected to the cam 28 rotates around the fixed point, thereby driving the slider 14 to slide on the slide rail 26;

[0050] S6: The detection container 8 moves to a specified position under the drive of the slider 14 and stops, the electromagnetic flowmeter 2 5 and the electric valve 2 7 on the reagent bottle 1 17 are opened, and when the drip value reaches the set threshold, the valve is closed, and the drive motor 30 continues to drive, so that the detection container 8 reciprocates on the slide rail 26 to ensure that the soft water and the reagent 1 are fully mixed, and the drive motor 30 continues to drive;

[0051] S7: When the detection container 8 reaches the reagent 2 adding station, the drive stops, the reagent tube electromagnetic flowmeter 3 20 and the electric valve 3 21 on the reagent bottle 2 19 are opened, and when the drip value reaches the set threshold, the valve is closed, and the drive motor 30 continues to drive, so that the detection container 8 reciprocates on the slide rail 26 to ensure that the soft water and the reagent 2 are fully mixed;

[0052] S8: After the soft water and the two reagents are fully mixed, the driving motor 30 drives the detection container 8 to the initial position, and the color sensor 11 works to detect whether the color of the liquid in the container 8 changes to a specified color. If it changes to a specified color, the alarm light 1 221 goes out, and the alarm light 2 222 is always on in yellow, indicating that the device is in a state of waiting to check and confirm the detection result;

[0053] S9: If the color changes to an abnormal color, the alarm light 1 221 and the alarm light 222 will both light up in red and flash continuously, and an alarm will sound, indicating that the device is in a state of unqualified test results and waiting for manual re-test;

[0054] S10: Regardless of whether the test result is normal or not, the timer 23 restarts the next time according to the set time. When the timer 23 is close to reaching the next test time, the rotary cylinder 9 is started to drive the container support frame 12 to rotate, so that the test container 8 is turned over to pour out the waste liquid from the last test into the waste liquid collection bucket. After a certain period of time, the rotary cylinder 9 is driven to rotate again, and the test container 8 returns to the initial position;

[0055] S11: At this time, the electromagnetic flowmeter 2 and the electric valve 3 on the soft water branch 4 are opened, a small amount of soft water is set to enter the detection container 8, and then the corresponding valve is closed, and the driving motor 30 is started to drive the detection container 8 to do reciprocating motion, and the detection container 8 is shaken and cleaned;

[0056] S12: Return to the initial position, pour out the cleaning solution, and repeat step 11 to clean the detection container 8 again;

[0057] S13: After the cleaning is completed, the next automatic measurement and detection is performed, i.e. steps 3-9 are repeated;

[0058] S14: If manual detection is required, that is, when the automatic detection switch 251 of the device is turned on, the manual detection switch 252 is pressed, and the device will not be affected by the timer 23 and directly perform a soft water detection operation;

[0059] S15: When shutdown is required, the automatic detection switch 251 of the device is pressed again and the device is shut down.

[0060] In summary, the utility model provides an automatic detection and alarm device for soft water quality. By designing a measuring device, an automatic detection device and an alarm device, the tedious steps of manually measuring and detecting the soft water quality are eliminated, labor is effectively saved, and the soft water capacity can be accurately measured to improve the accuracy of the detection.
