[0027] See also Figure 1 , Figure 1 The schematic diagram of the principle of the slightly acidic hypochlorous acid water generating device 100 in one embodiment of the present application is shown. The slightly acidic hypochlorous acid water generating device 100 provided in one embodiment of the present application includes an electrolytic cell 110, a mixing assembly 120 and a water supply pipe 130. Figure 2 As shown, the slightly acidic hypochlorous acid water generating device 100 further includes a shell 170 and a door 180 rotatably connected to the shell 170. The shell 170 is hollow to prevent other components of the slightly acidic hypochlorous acid water generating device 100 from being exposed, thereby playing a role of aesthetics and protection.

[0028] The electrolytic cell 110 includes an electrolytic plate 111 for electrolyzing an electrolyte. Usually, the electrolyte is a 2-6% dilute hydrochloric acid solution. The principle of electrolyzing hypochlorous acid can be simply summarized as follows: Under the action of the current generated by electrolysis, chloride ions (CI- ) and water molecules (H2O) undergo an oxidation-reduction reaction to generate hypochlorous acid (HClO), chlorine (Cl2) and sodium hydroxide (NaOH). The electrolytic plate 111 has two electrodes, one is the anode 1111 (i.e., the oxidation electrode), and the other is the cathode 1112 (i.e., the reduction electrode). The two electrodes are connected by a DC power supply to form a closed circuit. The anode 1111 of the electrolytic plate 111 has an iridium-containing layer and a tantalum-containing layer arranged in opposite directions. Preferably, the front side of the anode 1111 of the electrolytic plate 111 is provided with an iridium-containing layer coating, and the back side of the anode 1111 of the electrolytic plate 111 is provided with a tantalum-containing layer coating. Compared with the prior art in which the electrolytic plate 111 is only provided with an iridium-containing layer coating, the additional tantalum-containing layer coating can make the electrolysis reaction as complete as possible, so that the content of the generated hypochlorous acid (HClO) and chlorine (CI2) is linearly related to the content of the added electrolyte, so that the content of the generated hypochlorous acid (HClO) and chlorine (CI2) can be controlled by the flow rate of the electrolyte introduced into the electrolytic cell 110, thereby achieving a stable pH value of the generated slightly acidic hypochlorous acid water.

[0029] like Figure 1 As shown, one end of the mixing assembly 120 is connected to the electrolytic cell 110 and is used to receive the acidic raw liquid generated by electrolysis, and the other end is provided with a water outlet 121 for discharging slightly acidic hypochlorous acid water. The water supply pipe 130 is connected to the mixing assembly 120 and is used to provide raw water to the mixing assembly 120. Usually, the raw water is tap water. The function of the raw water is to dilute the acidic liquid generated in the electrolytic cell 110 so that the acidic liquid and the raw water are mixed to form slightly acidic hypochlorous acid water.

[0030] In one embodiment, the slightly acidic hypochlorous acid water generating device 100 further includes a pH detection member 140, i.e., a pH value measuring instrument, which can be any pH value measuring instrument in the prior art. The pH detection member 140 acts on the water outlet 121 and is used to detect the pH of the liquid flowing through the water outlet 121, i.e., to detect the pH value of the slightly acidic hypochlorous acid water discharged from the water outlet 121, so as to evaluate whether the pH value of the slightly acidic hypochlorous acid water generated by the slightly acidic hypochlorous acid water generating device 100 meets the standard.

[0031] In one embodiment, the water supply pipe 130 is provided with a water supply valve 131 for controlling the flow rate of raw water in the water supply pipe 130, so as to control the content of raw water in the mixed liquid flowing through the water outlet 121 by the flow rate of raw water. Generally, the pH of raw water is about 7, which is slightly higher than the pH value of slightly acidic hypochlorous acid water. When the pH value of slightly acidic hypochlorous acid water is too high, it means that the content of raw water in the mixed liquid flowing through the water outlet 121 is too high, and the flow rate of raw water in the water supply pipe 130 can be reduced by adjusting the water supply valve 131, thereby reducing the content of raw water in the mixed liquid flowing through the water outlet 121; and when the pH value of slightly acidic hypochlorous acid water is too low, it means that the content of raw water in the mixed liquid flowing through the water outlet 121 is too low, and the flow rate of raw water in the water supply pipe 130 can be increased by adjusting the water supply valve 131, thereby increasing the content of raw water in the mixed liquid flowing through the water outlet 121.

[0032] Combination Figure 3 As shown, in one embodiment, the control component 190 is configured to receive the pH detected by the pH detection component 140 and control the opening and closing degree of the water supply valve 131 according to the pH. The water supply valve 131 is controlled by the control component 190 to automatically adjust the opening and closing degree of the water supply valve 131 according to the pH value of the mixed liquid flowing through the water outlet 121, thereby adjusting the flow rate of the raw water in the water supply pipe 130 and the raw water content in the mixed liquid flowing through the water outlet 121, so as to achieve the purpose of adjusting the pH value of the mixed liquid flowing through the water outlet 121.

[0033] The water mixed with chlorine to generate hypochlorous acid water is usually directly provided by tap water. The amount of tap water is affected by the water consumption of residents, and there are problems of unstable water pressure and water volume fluctuation, which causes the pH value of slightly acidic hypochlorous acid water to fluctuate. In some embodiments, the water supply pipe 130 is also provided with a flow meter 132 for detecting the flow of raw water flowing through the water supply pipe 130, so as to monitor the flow of raw water, and combine with the adjustment of the flow by the water supply valve 131 to achieve a stable raw water flow.

[0034] like Figure 1 and Figure 2 As shown, in one embodiment, the mixing assembly 120 includes an acid storage element 160, which is connected to the electrolytic cell 110, the water outlet 121 and the water supply pipe 130, and the acid storage element 160 is used to receive raw water and acidic stock solution generated by electrolysis, and the acid storage element 160 includes a storage space for holding an acidic liquid formed by mixing the raw water and the acidic stock solution.

[0035] like Figure 1 and Figure 2As shown, in one embodiment, the mixing component 120 includes an alkaline storage element 150, which is connected to the water outlet 121, and the alkaline storage element 150 includes a storage space for holding an alkaline liquid, and the alkaline liquid is any alkaline solution that can react with an acidic liquid to neutralize the acidic liquid, so as to increase the pH value of the mixed liquid flowing through the water outlet 121 by an alkaline solution with a pH value greater than 7.

[0036] like Figure 1 As shown, in one embodiment, the mixing assembly 120 includes an acidic tube 122, an alkaline tube 123 and a water outlet pipe 124 that are connected to each other, wherein the acidic tube 122 is connected to the acidic storage element 160, the alkaline tube 123 is connected to the alkaline storage element 150, and the water outlet 121 is provided on the water outlet pipe 124, thereby realizing the connection between the alkaline liquid and the acidic liquid so as to neutralize the acidic liquid by the alkaline liquid.

[0037] In one embodiment, the acid pipe 122 is provided with an acid valve 126 for controlling the flow rate of the acid liquid in the acid pipe 122 to adjust the flow rate of the acid liquid in the acid pipe 122 and further adjust the content of the mixed liquid acid liquid flowing through the water outlet 121 .

[0038] In one embodiment, the control component 190 is configured to receive the pH detected by the pH detection component 140 and control the opening and closing degree of the acid valve 126 according to the pH. The acid valve 126 is controlled by the control component 190 to automatically adjust the opening and closing degree of the acid valve 126 according to the pH value of the mixed liquid flowing through the water outlet 121, thereby adjusting the flow rate of the acid liquid in the acid valve 126 and the content of the acid liquid in the mixed liquid flowing through the water outlet 121, so as to achieve the purpose of adjusting the pH value of the mixed liquid flowing through the water outlet 121.

[0039] In one embodiment, the alkaline pipe 123 is provided with an alkaline valve 125 for controlling the flow rate of the alkaline liquid in the alkaline pipe 123 to adjust the flow rate of the alkaline liquid in the alkaline pipe 123 and further adjust the content of the mixed liquid alkaline liquid flowing through the water outlet 121 .

[0040] In one embodiment, the control component 190 is configured to receive the pH detected by the pH detection component 140 and control the opening and closing degree of the alkaline valve 125 according to the pH. The alkaline valve 125 is controlled by the control component 190 to automatically adjust the opening and closing degree of the alkaline valve 125 according to the pH value of the mixed liquid flowing through the water outlet 121, thereby adjusting the flow rate of the alkaline liquid in the alkaline valve 125 and the content of the alkaline liquid in the mixed liquid flowing through the water outlet 121, so as to achieve the purpose of adjusting the pH value of the mixed liquid flowing through the water outlet 121.

[0041] The slightly acidic hypochlorous water generating device 100 in the above embodiment, by providing the iridium-containing layer and the tantalum-containing layer opposite to each other on the electrolytic plate 111, allows the electrolysis reaction to react as completely as possible, so that the content of the generated hypochlorous acid (HClO) and chlorine gas (Cl2) can be controlled by the flow rate of the electrolyte introduced into the electrolytic cell 110, thereby achieving a stable pH value of the generated slightly acidic hypochlorous water.
