fig. 2 is a schematic diagram of the connection relationship between the electric devices according to the present invention.

In the figure: the device comprises an activated carbon filter 1, an RO membrane filter 2, a water delivery pipe 3, a third electromagnetic valve 4, a PP fiber filter 5, a standby filter 6, a first electromagnetic valve 7, a turbidity sensor 8, a nitrate sensor 9, a heavy metal sensor 10, a chloride ion sensor 11, a floating ball liquid level switch 12, a water measuring tank 13, a second electromagnetic valve 14 and a water guide pipe 15.

Detailed Description

As shown in fig. 1 and 2, the system for reminding filter element replacement of a direct drinking machine comprises a multi-stage filter which is sequentially communicated through a water pipe 3, and further comprises a water measuring tank 13, the water pipe 3 communicated with a filter water outlet is communicated with the water measuring tank 13 through a water guide pipe 15, a first electromagnetic valve 7 is installed on the water guide pipe 15, the bottom of the water measuring tank 13 is communicated with a water discharge pipe, a second electromagnetic valve 14 is installed on the water discharge pipe, a turbidity sensor 8, a nitrate sensor 9, a heavy metal sensor 10, a chloride ion sensor 11 and a float ball liquid level switch 12 are arranged on the water measuring tank 13, the turbidity sensor 8, the nitrate sensor 9, the heavy metal sensor 10, the chloride ion sensor 11 and the float ball liquid level switch 12 are connected with the input end of a controller through a field bus, the first electromagnetic valve 7 and the second electromagnetic valve 14 are connected with the output end of the controller, the controller is connected with a remote terminal through a wireless communication module, and a display screen is connected with the controller. Wherein the controller is an MCU controller, the wireless communication module is a 4G communication module, and the remote terminal is a desktop computer.

The utility model discloses a working process does: when no one uses the direct drinking water dispenser at 3 am every night, the system is reminded to start working, firstly, the controller controls the first electromagnetic valve 7 connected with the first-stage filter to be opened, water filtered by the first-stage filter enters the water measuring tank 13, when the floater liquid level switch 12 detects that the water level reaches a high level (the water level reaches the measuring position of each sensor), the controller controls the first electromagnetic valve 7 to be closed, the turbidity sensor 8, the nitrate sensor 9, the heavy metal sensor 10 and the chloride ion sensor 11 transmit the monitored data to the remote terminal through the wireless communication module, the remote terminal compares the data transmitted by each sensor with a preset value, if the data exceeds the preset value, the data is displayed on a computer display, meanwhile, the data is displayed on a display screen connected with the controller, if the data does not exceed the preset value, the data is not displayed, after the sensors detect, the controller controls the second electromagnetic valve 14 to be opened, water in the water measuring tank 13 is discharged, when the liquid level switch 12 detects that the water is discharged to a low level, the controller controls the second electromagnetic valve to be closed after the water level 145, and the water in the water measuring tank 13 is drained at the moment; and then the controller controls the first electromagnetic valve 7 connected with the second-stage filter to be opened, and the filter element condition of the second filter is detected according to the method, the detection on all the filter elements is completed repeatedly, and finally, the computer checks, summarizes, displays and prints all the filter element conditions of the direct water dispenser in each district. After the staff goes to work the next day, according to the service condition of the direct drinking machine filter elements in each district of the whole city printed by the computer, the staff goes to the warehouse to get the filter elements with corresponding quantity and specification, and finally goes to the district to replace the direct drinking machine filter elements with the filter elements needing to be replaced.

The water delivery pipe 3 is communicated with the PP fiber filter 5, the RO membrane filter 2 and the activated carbon filter 1 in sequence. The PP fiber filter 5 can effectively filter out harmful substances such as silt, large suspended particles, rust, bugs and the like in tap water; the RO membrane filter 2 can effectively filter out impurities, salt and heavy metal ions in water; the activated carbon filter 1 can further adsorb peculiar smell in water, adjust the taste of the drinking water, and release trace elements, so that the drinking water has better taste.

A plurality of standby filters 6 are communicated with one side of the PP fiber filter 5 in parallel, third electromagnetic valves 4 are arranged on water conveying pipes 3 which are communicated with the standby filters 6 and the PP fiber filter 5, and the third electromagnetic valves 4 are connected with the output end of the controller. The spare filter 6 is the same as the PP fiber filter 5.

The replacement frequency of the filter element of the PP fiber filter 5 is 3 times that of the filter element of the RO membrane filter 2, so that 2 spare filters 6 are bypassed on one side of the PP fiber filter 5, when one of the PP fiber filter 5 filter elements is used up, the controller controls the third electromagnetic valve 4 communicated with the PP fiber filter 5 to be closed and the third electromagnetic valve 4 communicated with the spare filter 6 to be opened so as to switch the PP fiber filter 5 to the spare filter 6, when both the spare filter 6 and the PP fiber filter 5 are used up, the filter element of the RO membrane filter 2 is also used up, thus a worker can replace the RO membrane filter 2 simultaneously when replacing the PP fiber filter 5 and the spare filter 6, and further reduce the labor intensity of workers.
