As shown in fig. 1-2, in an embodiment of the present invention, there is provided a water bathing pipeline system 1, the water bathing pipeline system 1 including an electrolyzer and a control module 13.

In one example, tap water enters the inside of the acid electrode chamber 11 through the acid inlet pipe 111 and enters the inside of the alkaline electrode chamber 12 through the alkaline inlet pipe, at this time, the tap water in the acid electrode chamber 11 and the tap water in the alkaline electrode chamber 12 are electrolyzed by the anode sheet in the acid electrode chamber 11 and the cathode sheet in the alkaline electrode chamber 12 respectively, so as to electrolyze the tap water in the acid electrode chamber 11 into an acid solution and electrolyze the tap water in the alkaline electrode chamber 12 into an alkaline solution, and furthermore, the user obtains the acid solution through the water outlet pipe 112 communicated with the acid electrode chamber 11, and the skin is cleaned by the acid solution, so that the balance of the microbial environment on the surface of the skin can be maintained, and the problems of drying out oil on the skin and the like can be prevented.

In one example, the acidic water inlet pipe 111 and the alkaline water inlet pipe 123 are communicated with each other, a water pump connected to the acidic water inlet pipe is arranged in the acidic electrode chamber 11, tap water in the acidic electrode chamber 11 is electrolyzed by an anode sheet in the acidic electrode chamber 11 to generate an acidic solution, and the acidic solution in the acidic electrode chamber 11 is pumped into the alkaline electrode chamber 12 by the water pump, so that the acidic solution is filled in the alkaline electrode chamber 12, the cathode sheet is soaked in the acidic solution, scale on the surface of the cathode sheet is washed and peeled off by the acidic solution, and the electrolysis efficiency of the cathode sheet is improved.

In the embodiment of the present invention, the water outlet pipe 112 is provided with a water outlet control valve 113, the alkaline water inlet pipe 123 is provided with an alkaline water inlet valve 122, the water outlet control valve 113 and the alkaline water inlet valve 122 are electrically connected to the control module 13, and the control module 13 is configured to control the alkaline water inlet valve 122 to be closed after checking that the water outlet control valve 113 is closed, so that the acidic solution in the acidic electrode chamber 11 is discharged to the alkaline electrode chamber 12, so that the cathode plate in the alkaline electrode chamber 12 is soaked in the acidic solution, and scale on the surface of the cathode plate is removed, so that the surface resistance distribution of the cathode plate is more uniform, and the service life of the cathode plate is prolonged.

In one example, after the user stops using the acidic solution discharged from the water outlet pipe 112 and closes the water outlet control valve 113, the water outlet control valve 113 feeds back an electric signal to the control module 13 and triggers the control module 13 to close the alkaline water inlet valve 122, so that the acidic solution in the acidic pole chamber 11 enters the alkaline pole chamber 12, and the cathode plate is soaked in the acidic solution. The electrolytic cell comprises a diaphragm 14 arranged between an acid electrode chamber 11 and an alkaline electrode chamber 12, an acid solution in the acid electrode chamber 11 enters the alkaline electrode chamber 12 through the diaphragm 14, that is, after a control module 13 controls an alkaline water inlet valve 122 to be closed, tap water enters the acid electrode chamber 11 through an acid water inlet pipeline 111, and as a water outlet pipeline 112 communicated with the acid electrode chamber 11 is closed by a user, tap water continuously entering the acid electrode chamber 11 causes the pressure in the acid electrode chamber 11 to be increased, so that the acid solution in the acid electrode chamber 11 flows into the alkaline electrode chamber 12 through the diaphragm 14, a cathode sheet in the alkaline electrode chamber 12 is soaked in the acid solution, scales on the surface of the cathode sheet are removed, the surface resistance distribution of the cathode sheet is more uniform, the service life of the cathode sheet is prolonged, the utilization rate of the cathode sheet is improved, and the power consumption is reduced.

In an embodiment of the present invention, the separator 14 includes any one of an anion/cation exchange membrane, a proton membrane, a microfiltration membrane, and an ultrafiltration membrane.

In one example, the separator 14 is an anion exchange membrane containing a basic group such as a quaternary ammonium group [ -N (CH3)3OH ], an amine group (-NH 2), or an imine group (-NH 2). They can generate OH-ions in water and can exchange with various anions according to the following exchange principle:

R—N(CH3)3OH+Cl-R—N(CH3)3Cl+OH-

in one example, the membrane 14 is an anion exchange membrane, and the cation exchange membrane mostly contains acidic groups such as sulfonic acid group (-SO 3H), carboxyl group (-COOH), or phenol group (-C6H 4OH), wherein hydrogen ions can exchange with metal ions or other cations in the solution. For example, high polymers of styrene and divinylbenzene are sulfonated to obtain a strongly acidic cation exchange membrane, the structural formula of which can be simply represented as R-SO 3H, wherein R represents a membrane matrix, and the exchange principle is as follows:

2R—SO3H+Ca2+(R—SO3)2Ca+2H+

In one example, the membrane 14 is an ultrafiltration membrane, and the particles with the diameter of 1nm to 30nm are retained under pressure driving by using a sieving mechanism of the ultrafiltration membrane, and the acid solution flows to the low-pressure side of the membrane through the micropores on the ultrafiltration membrane under the action of pressure difference, so that the particles larger than the pores of the membrane are retained as a permeate, and the separation of the particles in the acid solution from the acid solution is realized.

In one example, after the user stops using the acidic solution discharged from the water outlet pipe 112 and closes the water outlet control valve 113, at this time, the water outlet control valve 113 feeds back an electric signal to the control module 13 and triggers the control module 13 to close the alkaline water inlet valve 122, and simultaneously opens the acidic water outlet valve 152, tap water enters the acidic electrode chamber 11 through the acidic water inlet pipe 111, the anode plate electrolyzes tap water in the acidic electrode chamber 11 to generate an acidic solution, tap water continuously entering the acidic electrode chamber 11 causes the pressure in the acidic electrode chamber 11 to increase, and presses the acidic solution in the acidic electrode chamber 11 to enter the water storage tank 15 through the water outlet pipe 112, and then enters the alkaline electrode chamber 12 through the water storage tank 15 and the acidic water outlet pipe 151, so that the cathode plate in the alkaline electrode chamber 12 is soaked in the acidic solution, and scale on the surface of the cathode plate is removed under the action of the acidic solution, the surface resistance of the cathode plate is distributed more uniformly, the service life of the cathode plate is prolonged, the utilization rate of the cathode plate is improved, and the power consumption is reduced.

Specifically, the flow meter 16 starts to display the real-time reading of the current water flow after detecting the water flow, and the control module 13 controls the opening time of the acid drain valve 152 according to the volume S1 of the acid drain pipe, the volume S2 of the alkaline chamber, and the real-time reading v of the flow meter.

In one example, after the user stops using the acidic solution discharged from the water outlet pipe 112 and closes the water outlet control valve 113, at this time, the water outlet control valve 113 feeds back an electric signal to the control module 13 and triggers the control module 13 to close the alkaline water inlet valve 122 and simultaneously open the acidic water discharge valve 152, tap water enters the acidic pole chamber 11 through the acidic water inlet pipe 111, the flow meter 16 starts to detect the water flow entering the acidic pole chamber 11 and display a real-time reading of the water flow entering the acidic pole chamber 11, the tap water in the acidic pole chamber 11 is electrolyzed by the anode sheet in the acidic pole chamber 11 to generate the acidic solution, the tap water continuously entering the acidic pole chamber 11 causes the pressure in the acidic pole chamber 11 to increase and squeezes the acidic solution in the acidic pole chamber 11 into the water storage tank 15 through the water outlet pipe 112 and then enters the alkaline pole chamber 12 through the acidic water discharge pipe 151 from the water storage tank 15, during the process of entering the alkaline pole chamber 12, the control module 13 determines the volume of the acidic solution entering the alkaline pole chamber 12 by combining the volume S2 of the alkaline pole chamber, the volume S1 of the acidic water discharge pipeline and the real-time reading v of the flow meter, and when it is determined that the volume of the acidic solution entering the alkaline pole chamber 12 is equal to the sum of the volume S2 of the alkaline pole chamber and the volume S1 of the acidic water discharge pipeline, the control module 13 controls the acidic water discharge valve 152 to close, so as to ensure that the acidic solution is stopped from being discharged to the alkaline pole chamber 12 continuously after the acidic solution entering the alkaline pole chamber 12 is filled in the alkaline pole chamber 12, and avoid the phenomenon of water resource waste.

In a specific example, the volume S2 of the alkaline pole chamber is 20L, the volume S1 of the acidic water discharge pipe is 0.5L, the flow meter 16 detects that the average water flow into the acidic pole chamber 11 is 0.1L/S, that is, the real-time reading v of the flow meter is 0.1L/S, the control module 13 controls the opening time of the acidic water discharge valve 152 according to the volume S2 of the alkaline pole chamber, the volume S1 of the acidic water discharge pipe, and the water flow of the flow meter 16, the opening time of the acidic water discharge valve 152 is (the volume S2 of the alkaline pole chamber + the volume S1 of the acidic water discharge pipe) ÷ the real-time reading v of the flow meter, that is, the opening time of the acidic water discharge valve 152 is (20L +0.5L) ÷ 0.1L/S ÷ 205 seconds, and the opening time of the acidic water discharge valve 152 exceeds 205 seconds, the control module 13 controls the acidic water discharge valve 152 to close. Specifically, when the opening time of the acid drain valve 152 is 1 minute, that is, when the opening time of the acid drain valve 152 is 1 × 60 seconds, the total volume of the acid solution that enters the acid drain line 151 and the alkaline chamber 12 is 0.1L/s × 60 to 6L. At this time, the acidic drainage pipeline 151 is filled with the acidic solution, that is, the acidic solution in the acidic drainage pipeline 151 is 0.5L, the acidic solution in the alkaline chamber 12 is 5.5L, the alkaline chamber 12 is not filled with the acidic solution, and the control module 13 continues to control the acidic drainage valve 152 to be in the open state; when the open time of the acid drain valve 152 is 3 minutes, that is, when the open time of the acid drain valve 152 is 3 × 60 — 180 seconds, the total volume of the acid solution entering the acid drain line 151 and the alkaline pole chamber 12 is 0.1L/s × 180 — 18L. At this time, the acidic water discharge pipeline 151 is filled with the acidic solution, the amount of the acidic solution filled in the alkaline chamber 12 is 17.5L, the alkaline chamber 12 is not filled with the acidic solution, the control module 13 continues to control the acidic water discharge valve 152 to be in the open state, and when the open time for opening the acidic water discharge valve 152 is 3 minutes and 25 seconds, that is, when the open time for opening the acidic water discharge valve 152 is 3 × 60+25 seconds to 205 seconds, the total volume of the acidic solution entering the acidic water discharge pipeline 151 and the alkaline chamber 12 is 0.1L/s × 180 to 20.5L.

After the alkaline chamber 12 is filled with the acidic solution, the cathode sheet is soaked in the acidic solution of the alkaline chamber 12, and water scale on the surface of the cathode sheet can be removed under the action of the acidic solution, so that the surface resistance of the cathode sheet is distributed more uniformly, the service life of the cathode sheet is prolonged, the utilization rate of the cathode sheet is improved, and the power consumption is reduced.

It will be appreciated that the data of the volume S2 of the alkaline chamber and the volume S1 of the acid drain line are entered into the control module 13 by the user, which in turn enables the control module 13 to determine the open time of the acid drain valve 152 based on the real-time readings v of the flow meter and to control the closing of the acid drain valve 152 when the open time of the acid drain valve 152 is reached.

In another specific example, the volume S2 of the alkaline pole chamber is 20L, the volume S1 of the acid drain pipe is 0.5L, the flow meter 16 detects that the average water flow into the acid pole chamber 11 is 0.1L/S, that is, the real-time reading v of the flow meter is 0.1L/S, a liquid level sensor is disposed in the alkaline pole chamber 12, the volume of the alkaline pole chamber 12, that is, the volume of the acidic solution currently contained in the alkaline pole chamber 12 is detected by the liquid level sensor, the liquid level sensor is electrically connected to the control module 13 to transmit the volume data of the alkaline solution in the alkaline pole chamber 12 to the control module 13, and the control module 13 determines the opening time of the acid drain pipe 152 by combining the volume of the alkaline pole chamber 12, the acid drain pipe 151, and the real-time reading v of the flow meter.

For example, when the liquid level sensor detects that the amount of alkaline solution in the alkaline pole chamber 12 is 3L, the liquid level sensor detects that the amount of acidic solution currently contained in the alkaline pole chamber 12 is 20L-3L ═ 17L, the liquid level sensor transmits the detected amount data of the alkaline pole chamber 12 to the control module 13, the control module 13 controls the opening time of the acidic drain valve 152 according to the amount S2 of the alkaline pole chamber, the amount S1 of the acidic drain pipe, and the water flow rate of the flow meter 16, the opening time of the acidic drain valve 152 is (the amount S2 of the alkaline pole chamber + the amount S1 of the acidic drain pipe) ÷ the real-time reading v of the flow meter, that is, the opening time of the acidic drain valve 152 is (17L +0.5L) ÷ 0.1L/S ÷ 175 seconds, and the opening time of the acidic drain valve 152 exceeds 175 seconds, the control module 13 controls the acidic drain valve 152 to close. Specifically, when the opening time of the acid drain valve 152 is 1 minute, that is, when the opening time of the acid drain valve 152 is 1 × 60 seconds, the total volume of the acid solution that enters the acid drain line 151 and the alkaline chamber 12 is 0.1L/s × 60 to 6L. At this time, the acidic drainage pipeline 151 is filled with the acidic solution, that is, the acidic solution in the acidic drainage pipeline 151 is 0.5L, the acidic solution in the alkaline chamber 12 is 5.5L, the alkaline chamber 12 is not filled with the acidic solution, and the control module 13 continues to control the acidic drainage valve 152 to be in the open state; when the open time of the acid drain valve 152 is 2 minutes, that is, when the open time of the acid drain valve 152 is 2 × 60 — 120 seconds, the total volume of the acid solution entering the acid drain line 151 and the alkaline pole chamber 12 is 0.1L/s × 120 — 12L. At this time, the acidic water drainage pipeline 151 is filled with the acidic solution, the acidic solution filled in the alkaline chamber 12 is 11.5L, the alkaline chamber 12 is not filled with the acidic solution, the control module 13 continues to control the acidic water drainage valve 152 to be in the open state, when the open time for opening the acidic water drainage valve 152 is 2 minutes and 55 seconds, that is, when the open time for opening the acidic water drainage valve 152 is 2 × 60+55 seconds, that is, when the open time for opening the acidic water drainage valve 152 is 175 seconds, the total volume of the acidic solution entering the acidic water drainage pipeline 151 and the alkaline chamber 12 is 0.1L/s × 175.17.5L, since the alkaline chamber 12 is originally filled with 3L of the alkaline solution, the sum of the acidic solution and the alkaline solution in the alkaline chamber 12 is 20L, at this time, the acidic water drainage pipeline 151 is filled with the acidic solution, the acidic solution filled in the alkaline chamber 12 is 20L, the alkaline chamber 12 is filled with a mixed solution of 17L of the acidic solution and 3L of the alkaline solution, the control module 13 controls the acid drain valve 152 to close to avoid wasting water resources.

After the alkaline chamber 12 is filled with the acidic solution, the cathode plate is soaked in the mixed solution of the acidic solution and a small amount of alkaline solution of the alkaline chamber 12, and scale on the surface of the cathode plate can be removed under the action of the mixed solution, so that the surface resistance of the cathode plate is distributed more uniformly, the service life of the cathode plate is prolonged, the utilization rate of the cathode plate is increased, and the power consumption is reduced.

It can be understood that when the liquid level sensor detects that the capacity of the alkaline solution in the alkaline pole chamber 12 is greater than half of the capacity of the alkaline pole chamber 12, and the user closes the water outlet control valve 113, the control module 13 does not open the acidic water outlet valve 152, so as to prevent the capacity of the acidic solution filled in the alkaline pole chamber 12 from being smaller than the capacity of the alkaline solution in the alkaline pole chamber 12, and further prevent the mixed solution of the acidic solution and the alkaline solution from being alkaline and being unable to clean the scale on the surface of the cathode sheet. When a user discharges the alkaline solution in the alkaline electrode chamber 12 from the waste water pipe 124, and the liquid level sensor detects that the capacity of the alkaline solution in the alkaline electrode chamber 12 is less than half of the capacity of the alkaline electrode chamber 12, after the user closes the water discharge control valve 113, the control module 13 controls to open the acidic water discharge valve 152, so that the acidic solution enters the alkaline electrode chamber 12 through the acidic water discharge valve 152, and after the alkaline electrode chamber 12 is filled with a mixed solution of a slow acidic solution and an alkaline solution, the control module 13 controls to close the acidic water discharge valve 152, and since the capacity of the acidic solution in the mixed solution is greater than the capacity of the alkaline solution, the mixed solution in the alkaline electrode chamber 12 is acidic, and scales on the surface of the cathode sheet can be cleaned.
