People can never leave air and water, and the requirements of people on water quality are higher and higher nowadays when people pay more and more attention to water safety. A water purifier is a common device for purifying water, and people want to obtain safe and healthy water through the purification effect of the water purifier, and the water can be purified by a water purifying device of the water purifier after entering the water purifier and then be supplied to users.

Example one

Fig. 1 is a flowchart of a water quality abnormality determination method according to an embodiment of the present invention, which is applicable to a situation where a change in water quality needs to be monitored in real time, and the method is applied to a water purification apparatus including a TDS detection unit disposed at a water inlet, and the method can be executed by a water quality abnormality determination apparatus, as shown in fig. 1, and specifically includes the following steps:

and 110, acquiring a TDS value of the inlet water based on the inlet water TDS detection unit.

Wherein, TDS detecting element of intaking can set up in water purification unit's delivery port, and this TDS detecting element of intaking can be TDS needle or TDS pen etc to can be connected with water purification unit's treater communication, be used for sending the dissolubility solid total amount of water inlet to the treater.

TDS values indicate the dissolved solids contained in 1 liter of water. Higher TDS values indicate more solutes in the water. TDS values refer to the total amount of total solutes in the water, including the content of both inorganic and organic species. Since organic matter and inorganic matter in molecular form contained in natural water are not generally considered, the salt content is generally referred to as total dissolved solids. Generally, the higher the conductivity, the higher the salt content and the higher the TDS value. Water with TDS value more than 300mg/L is polluted water, and the drinking of water with TDS value more than 300mg/L by human body may cause damage to health.

Specifically, the incoming water TDS can continuously monitor the incoming water TDS value of the water purification unit water inlet to can send the incoming water TDS value to the water purification unit's treater based on wireless communication or wired communication.

And 120, sequencing the intake water TDS values based on bubbling sequencing, and determining a maximum intake water TDS value and a minimum intake water TDS value in a preset time period.

The preset time period may be one hour.

Specifically, the processor may rank all of the intake TDS values that are obtained continuously based on a bubbling ranking after obtaining the real-time intake TDS values, and may determine a maximum intake TDS value and a minimum intake TDS value among all of the intake TDS values that are obtained within any one hour.

In the embodiment of the invention, after each incoming water TDS value is obtained, the incoming water TDS value can be inserted into the incoming water TDS value sequence based on bubbling sequencing, the incoming water TDS value sequence within one hour is determined by taking the current moment as the starting moment, and then the maximum incoming water TDS value and the minimum incoming water TDS value within one hour can be determined.

Of course, after the incoming water TDS values within an hour are sorted, the values at both ends in the obtained incoming water TDS value sequence can be respectively determined as the maximum incoming water TDS value and the minimum incoming water TDS value.

Step 130, determining a maximum influent water difference value according to the current influent TDS value and the maximum influent TDS value, and determining a minimum influent water difference value according to the current influent TDS value and the minimum influent TDS value.

Specifically, the difference between the current incoming water TDS value and the maximum incoming water TDS value can be calculated to obtain the maximum incoming water difference value, and the difference between the current incoming water TDS value and the minimum incoming water TDS value can also be calculated to obtain the minimum incoming water difference value.

And step 140, if the maximum water inlet difference value or the minimum water inlet difference value is larger than a water quality threshold value, determining that the water quality is abnormal.

Wherein the water quality threshold can be 250 mg/L.

Specifically, if the calculated maximum inlet water difference value or the calculated minimum inlet water difference value is greater than the water quality threshold value, it indicates that the inlet water TDS value of the water purification apparatus has changed greatly in a short time, and the water entering the water purification apparatus may harm the health of the human body, so that it may be determined that the water quality is abnormal.

Of course, if the maximum inlet water difference value and the minimum inlet water difference value are both smaller than the water quality threshold value, the water quality is determined to be normal.

In the embodiment of the invention, the processor can continuously receive the incoming water TDS values sent by the incoming water TDS detection unit for calculation and sequencing, for example, if the received first incoming water TDS value is 460mg/L, the processor waits for the second incoming water TDS value; if the second incoming water TDS value is 470mg/L, bubble sorting is carried out on 460mg/L and 470mg/L, meanwhile, the difference value between 460mg/L and 470mg/L is determined, and if the difference value is smaller than 250mg/L, the incoming water TDS values are continuously received to carry out bubble sorting and calculation of the difference value; and comparing, sequencing and reporting to determine that the water quality is abnormal until the difference value is greater than 250mg/L, and sending the water quality abnormal information to the user terminal.

It should be noted that, in practical application, after the processor acquires the incoming water TDS value based on the incoming water TDS detection unit, the processor may send the incoming water TDS value to the server, and then the server may execute step 120 and step 140, so as to determine that the water quality is abnormal.

The water quality abnormity determining method provided by the embodiment of the invention is applied to water purifying equipment, wherein the water purifying equipment comprises a water inlet TDS detection unit arranged at a water inlet, and the method comprises the following steps: acquiring a incoming water TDS value based on the incoming water TDS detection unit; sorting the intake water TDS values based on bubbling sorting, and determining a maximum intake water TDS value and a minimum intake water TDS value within a preset time period; determining a maximum influent water difference value for a current influent TDS value and the maximum influent TDS value, and a minimum influent water difference value for the current influent TDS value and the minimum influent TDS value; and if the maximum water inlet difference value or the minimum water inlet difference value is larger than a water quality threshold value, determining that the water quality is abnormal. Above-mentioned technical scheme continuously acquires the incoming water TDS value of water purification unit water inlet to calculate the difference of present incoming water TDS value and the biggest incoming water TDS value and the minimum incoming water TDS value in the preset time quantum respectively, if arbitrary difference is greater than the quality of water threshold value, then confirm that quality of water is unusual, realized that real-time definite quality of water changes, and then confirm that quality of water is unusual, in order to ensure the safety and the health of user's water.

Example two

Fig. 2 is a flowchart of a water quality abnormality determination method according to a second embodiment of the present invention, which is embodied on the basis of the first embodiment. In an embodiment of the present invention, the method may also be applied to a water purification apparatus, the water purification apparatus including: set up in the total dissolved solids TDS detecting element of intaking of water inlet and set up in the play water TDS detecting element of delivery port. As shown in fig. 2, the method may further include:

and 210, acquiring a TDS value of the inlet water based on the inlet water TDS detection unit.

And step 211, sequencing the intake water TDS values based on bubbling sequencing, and determining a maximum intake water TDS value and a minimum intake water TDS value in a preset time period.

Step 212, determining a maximum influent water difference value according to the current influent TDS value and the maximum influent TDS value, and determining a minimum influent water difference value according to the current influent TDS value and the minimum influent TDS value.

And 213, determining that the water quality is abnormal if the maximum water inlet difference value or the minimum water inlet difference value is larger than a water quality threshold value.

And step 214, sending the water quality abnormity information to a user terminal to remind a user to check the water quality.

In one embodiment, the execution main body of step 211-213 is a processor of the water purification apparatus, in this case, the water purification apparatus may include a bluetooth unit, and the water purification apparatus may be in communication connection with the user terminal through the bluetooth unit, and when it is determined that the water quality is abnormal, send the water quality abnormality information to the user terminal to remind the user to check the water quality.

In another embodiment, the execution subject of step 211-213 is a server, in which case, the water purification apparatus may include a wireless network unit, the water purification apparatus may be in communication connection with the server through the wireless network unit, and the server may also be in communication connection with the user terminal. The server can receive the incoming water TDS value that water purification unit sent to when confirming quality of water is unusual, with quality of water abnormal information transmission to user terminal, and remind the user to inspect quality of water in time.

Step 215, acquiring a effluent TDS value based on the effluent TDS detection unit.

Wherein, go out water TDS detecting element and can set up in water purification unit's delivery port, this play water TDS detecting element also can be for TDS needle or TDS pen etc. also can be with water purification unit's treater communication connection for the dissolubility solid total amount with the delivery port sends the treater to.

Specifically, go out the water TDS value that water TDS can continuously monitor the purifier delivery port to can send out water TDS value to purifier's treater based on wireless communication or wired communication.

And step 216, sequencing the effluent TDS values based on bubbling sequencing, and determining a maximum effluent TDS value and a minimum effluent TDS value in a preset time period.

Also, the preset time period may be one hour.

Specifically, the processor may sort all of the effluent TDS values that are obtained continuously based on a bubbling sort after the real-time effluent TDS values are obtained, and may determine a maximum effluent TDS value and a minimum effluent TDS value among all of the effluent TDS values that are obtained within any one hour.

In the embodiment of the invention, after each effluent TDS value is obtained, the effluent TDS value can be inserted into the effluent TDS value sequence based on bubbling sequencing, and the effluent TDS value sequence within one hour is determined by taking the current moment as the starting moment, so that the maximum effluent TDS value and the minimum effluent TDS value within one hour can be determined.

Similarly, after the effluent TDS values within one hour are sorted, the values at both ends of the obtained effluent TDS value sequence can be respectively determined as the maximum effluent TDS value and the minimum effluent TDS value.

And 217, determining a maximum effluent difference value according to the current effluent TDS value and the maximum effluent TDS value, and determining a minimum effluent difference value according to the current effluent TDS value and the minimum effluent TDS value.

Specifically, the difference between the current effluent TDS value and the maximum effluent TDS value can be calculated to obtain a maximum effluent difference value, and the difference between the current effluent TDS value and the minimum effluent TDS value can also be calculated to obtain a minimum effluent difference value.

And step 218, if the maximum water outlet difference value or the minimum water outlet difference value is larger than a filter element threshold value, determining that a water purification filter element of the water purification equipment is damaged.

Wherein, the filter element threshold value can be 100 mg/L.

Specifically, if the calculated maximum effluent difference value or the calculated minimum effluent difference value is larger than the filter element threshold value, it indicates that the effluent TDS value of the water purifying device is changed greatly in a short time. Because the water of delivery port is the water after purifying, if the change of delivery port TDS value is great, the main reason probably is that the filter core damages, therefore can confirm that water purification unit's water purification filter core damages.

And of course, if the maximum water outlet difference value and the minimum water outlet difference value are both smaller than the filter element threshold value, the water purification filter element is determined to be normal.

Similarly, in practical application, after the processor acquires the effluent TDS value based on the effluent TDS detection unit, the processor can send the effluent TDS value to the server, and then the server can execute step 216 and 218, so as to determine that the water purification filter element is damaged.

In addition, the steps 215-218 may be performed simultaneously with the steps 210-213.

Step 219, sending the water purification filter element damage information to a user terminal to remind a user to replace the water purification filter element and/or check water quality.

In one embodiment, the execution main body of step 216 and step 218 is a processor of the water purification apparatus, in this case, the water purification apparatus may include a bluetooth unit, and the water purification apparatus may be in communication connection with a user terminal through the bluetooth unit, and when it is determined that the water purification filter element is damaged, send the information of the damaged water purification filter element to the user terminal, and remind the user to replace the water purification filter element and/or check the water quality.

In another embodiment, the execution subject of steps 216 and 218 is a server, in which case, the water purification apparatus may include a wireless network unit, the water purification apparatus may be in communication connection with the server through the wireless network unit, and the server may also be in communication connection with the user terminal. The server can receive the effluent TDS value that water purification unit sent to when confirming the water purification filter core and damaging, damage the information transmission to user terminal with the water purification filter core, and remind the user in time to change water purification filter core and/or inspection quality of water.

The water quality abnormity determining method provided by the embodiment of the invention is applied to water purifying equipment, wherein the water purifying equipment comprises a water inlet TDS detection unit arranged at a water inlet, and the method comprises the following steps: acquiring a incoming water TDS value based on the incoming water TDS detection unit; sorting the intake water TDS values based on bubbling sorting, and determining a maximum intake water TDS value and a minimum intake water TDS value within a preset time period; determining a maximum influent water difference value for a current influent TDS value and the maximum influent TDS value, and a minimum influent water difference value for the current influent TDS value and the minimum influent TDS value; and if the maximum water inlet difference value or the minimum water inlet difference value is larger than a water quality threshold value, determining that the water quality is abnormal. Above-mentioned technical scheme, continuously acquire the incoming water TDS value of water purification unit water inlet to calculate the difference of present incoming water TDS value and the biggest incoming water TDS value and the minimum incoming water TDS value in the preset time quantum respectively, if arbitrary difference is greater than the quality of water threshold value, then confirm that quality of water is unusual, realized that real-time determination quality of water changes, and then confirm that quality of water is unusual, and with quality of water abnormal information transmission to user terminal, and remind the user to inspect quality of water in time, and then ensure the safety and the health of user's water consumption.

In addition, the water outlet TDS value of the water outlet of the water purifying device can be continuously acquired, the difference value between the current water outlet TDS value and the maximum water outlet TDS value and the minimum water outlet TDS value in the preset time period is respectively calculated, if any difference value is larger than the filter element threshold value, the water purifying filter element is determined to be damaged, the state of the filter element is determined in real time, the damage information of the water purifying filter element is sent to a user terminal, the user is reminded to replace the water purifying filter element and/or check the water quality, and the safety and the health of the water for the user are further ensured.
