Fig. 1 schematically shows a schematic view of an apparatus for adjusting the ph of a bath effluent according to an embodiment of the present invention. As shown in fig. 1, the apparatus 100 for adjusting ph of bath effluent, the apparatus 100 includes:

the pH value adjusting device 101 is used for adjusting the pH value of the input first solution; the TDS detection device 102 is connected with the pH value adjusting device 101 and is used for detecting a TDS value of the first solution; the first pH value detection device 103 is connected with the pH value adjustment device 101, and is used for detecting the first pH value of the first solution output from the pH value adjustment device 101; a processor 104 configured to: acquiring a TDS value; controlling the first solution to be input into the pH value adjusting device 101 to work under the condition that the TDS value reaches a preset threshold value; acquiring a first pH value; and controlling the pH value adjusting device 101 according to the first pH value to obtain a second solution with the pH value as a target pH value.

As shown in fig. 1, the processor 104 is communicatively connected to the ph adjusting device 101, the TDS detecting device 102 and the first ph detecting device 103, and the processor 104 can control various components communicatively connected thereto. TDS check out test set is solubility solid detection device, and it can detect the TDS value in the solution promptly solubility solid total value.

The first solution is the solution which is input into the device 100 for adjusting the pH value of the bathing effluent from the water inlet 106. The second solution is an effluent solution with the pH value meeting the target pH value after passing through the pH value adjusting device 101. The TDS detection device 102 may detect a TDS value of the first solution entering from the water inlet port 106. Assuming that the first solution is a saturated saline solution, the TDS detection device 102 may detect a TDS value of the saturated saline solution. Processor 104 obtains the TDS value of the first solution detected by TDS detection device 102 and compares the TDS of the first solution with a TDS preset threshold stored within processor 104. In the case that the TDS value of the first solution detected by the TDS detecting device 102 received by the processor 104 reaches the preset threshold set by the processor, the processor 104 may control the first solution to enter the ph adjusting device 101. After the first solution enters the ph adjusting apparatus 101, the ph adjusting apparatus 101 may adjust the ph of the first solution. The pH value of the first solution is adjusted by the pH value adjusting device 101 and then the first solution is output, and the first pH value detecting device 103 arranged at the water outlet of the pH value adjusting device 101 detects the solution output by the pH value adjusting device 101. The processor 104 obtains the ph of the solution output from the ph adjusting device 101 through the first ph detecting device 103. The processor 104 compares the target ph value set by the user with the received ph value, and controls the ph value adjusting device 101 according to the target ph value, so that the ph value adjusting device 101 can output the second solution reaching the target ph value. For example, assuming that the target PH value set by the user is weakly acidic water having a PH value of 5.5, the second solution may be a weakly acidic effluent solution having a PH value of 5.5 after the adjustment by the PH adjusting device 101 is completed. The second solution is then output through the outlet end 105.

In an embodiment of the present invention, the apparatus 200 for adjusting the ph of the bath effluent as shown in fig. 2 further comprises: first filtration equipment 201, the first end of first filtration equipment 201 is connected with the end 106 of intaking of medium solution, and the second end is connected with TDS check out test set 102, and the third end is connected with salt case 202 for filter medium solution.

The processor 104 is further configured to: under the condition that the TDS value of first solution does not reach preset threshold, control first valve 203 and open to make the saturated salt solution that includes in the salt case 202 mix with medium solution, obtain the first solution that the TDS value reaches preset threshold.

The media solution entering the device is first filtered by a first filter means 201 connected to the water inlet end 106. For example, assuming that the medium solution is tap water, the first filtering device 201 may filter the tap water. The first filtering device 201 may include a pre-filter element and a softening resin, and tap water may be passed through the pre-filter element and the softening resin to remove hardness ions such as calcium and magnesium from the water, so as to soften the tap water passing through the first filtering device 201.

After passing through the first filter device 201, the medium solution may enter the salt tank 202 to obtain a saturated salt solution. TDS value detection can also be performed directly by the TDS detection device 102 on the media solution passing through the first filtration device 201. Processor 104 acquires the TDS value of the media solution detected by TDS detection device 102 and compares the acquired TDS value to a preset threshold of TDS set by processor 104.

The TDS detection device 102 may detect the TDS value of the mixed solution. If TDS check out test set 102 detects through the TDS value to the solution of mixing completion, it does not reach the TDS preset threshold value that processor 104 set up to judge this TDS value of the solution of mixing completion.

Assuming that the medium solution is tap water, softened tap water can be obtained after the filtering by the first filtering device 201 is completed. The filtered tap water may enter the salt tank 202 to obtain a saturated salt solution. The TDS detection device 102 may additionally detect the TDS value of the filtered tap water. If the detected TDS value does not reach the preset threshold set by the processor 104, the processor 104 may control to open the first valve 203, so that the saturated saline solution in the salt tank 202 enters the pipeline to be mixed with the filtered tap water. TDS check out test set 102 can detect the TDS value of the mixed solution that the running water that the saturated salt solution and filtration were accomplished formed, if the TDS value of mixed solution does not reach the preset threshold value that treater 104 set up, then treater 104 can control first valve 203 and open the ratio that increases the saturated salt solution in the mixed solution. The first solution is a mixed solution of which the TDS value reaches a preset threshold value when the TDS detection device 102 detects the mixed solution. The processor controls to input the first solution into the acid-base adjusting device 101 to adjust the pH value of the first solution, and detects the pH value of the adjusted first solution according to the first pH value detecting device 103. Until the first solution is adjusted to a second solution that meets the target ph value set by the processor. The processor controls the output of the second solution from the outlet end 105.

As shown in fig. 3, the processor 104 is also communicatively coupled to a fifth valve 301, a second filter device 303, and a heating device 302, and the processor 104 may control the various components communicatively coupled thereto.

As shown in fig. 3, the medium solution enters the first filtering device 201 through the water inlet end 106, and the first filtering device 201 can filter and soften the medium solution. Assuming that the medium solution is tap water, softened tap water can be obtained after the filtering by the first filtering device 201 is completed. The filtered tap water may enter the salt tank 202 to obtain a saturated salt solution. The TDS detection device 102 may additionally detect the TDS value of the filtered tap water. If the detected TDS value does not reach the preset threshold set by the processor 104, the processor 104 may control to open the first valve 203, so that the saturated saline solution in the salt tank 202 enters the pipeline to be mixed with the filtered tap water. TDS check out test set 102 can detect the TDS value of the mixed solution that the running water that the saturated salt solution and filtration were accomplished formed, if the TDS value of mixed solution does not reach the preset threshold value that treater 104 set up, then treater 104 can control first valve 203 and open the ratio that increases the saturated salt solution in the mixed solution.

The processor controls to input the first solution into the acid-base adjusting device 101 to adjust the pH value of the first solution, and detects the pH value of the adjusted first solution according to the first pH value detecting device 103. Until the first solution is adjusted to a second solution that meets the target ph value set by the processor. The processor 104 may control the fifth valve 301 to open so that the second solution enters the second filtering device 303. The second filtering device 303 may filter the second solution again, for example, the second filtering device 303 may filter ions such as hypochlorous acid ions in the second solution, which may cause harm to a human body. After the filtration is completed, the second solution is introduced into the heating device 302 from the second filtering device 303. The processor 104 may control the heating device 302 to heat the filtered second solution, and after the heating device 302 heats the second solution to the target temperature set by the user and stored in the processor, the processor controls the second solution reaching the target temperature to flow out from the water using end 304 and be provided to the user.

In an embodiment of the present invention, as shown in fig. 4, the apparatus 400 for adjusting ph of bath effluent includes: a front filter element 401; a resin 402; a salt box 403; a flow valve 404; a pump 405; a mixing tub 406; TDS detection device 407; a water valve 408; an electrolysis device 409; a pH value detection device 410; activated carbon 411; a heating device 412; a water inlet end 413; water is used to flush 414.

The first solution may then be directed into mix tank 406. Further, the medium solution entering from the water inlet end 413 can be partially split into the salt tank 403 after passing through the pre-filter element 401, so that an appropriate amount of salt can be added through the salt tank 403 to obtain a corresponding saturated salt solution. The processor (not shown) may control the pump 405 to be turned on to pump the saturated salt solution in the salt tank 403 into the mixing tank 406 to obtain a mixed solution of the first solution and the saturated salt solution, i.e., the mixed solution in the mixing tank 406 may be formed by mixing the first solution and the saturated salt solution. The TDS detection device 407 can detect the TDS value of the mixed solution in the water mixing barrel 406 at this time, and send the detection value of the TDS to the processor. The processor may compare the detected actual TDS value to a set TDS preset threshold to determine whether the TDS value of the mixed solution reaches the preset threshold.

If the pH value of the effluent solution does not reach the target pH value, the processor can adjust the pH value of the electrolyzed solution by controlling the current or voltage at the two ends of the electrolysis equipment 409 until the actual pH value of the solution output by the electrolysis equipment 409 reaches the target pH value.

Further, after the actual ph of the solution output from the electrolysis device 409 reaches the target ph, the solution may be filtered through the activated carbon 411. For example, the hypochlorous acid ions in the solution are filtered to avoid the harm to human body. The processor may also transfer the filtered solution to a heating device 412.
