[0027] See also Figure 1 , Figure 1 The schematic diagram of the principle of a 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 water supply pipe 120, an acid storage element 130, a water outlet pipe 140, an alkaline storage element 150, a pH detection element 160 and a control element 190. Figure 2 and Figure 3 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 redox reactions 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 that are arranged opposite to each other. 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 electrolytic reaction as complete as possible, so that the content of the generated hypochlorous acid (HClO) and chlorine (Cl2) can be controlled by the flow rate of the electrolyte introduced into the electrolytic cell 110, thereby achieving the stability of the pH value of the generated slightly acidic hypochlorous acid water.

[0029] The water supply pipe 120 is connected to the acid storage element 130 and is used to provide raw water to the acid storage element 130. Usually, the raw water is tap water. The function of the raw water is to dilute the acid liquid generated in the electrolytic cell 110 so that the acid liquid and the raw water are mixed to form slightly acidic hypochlorous acid water.

[0030] The acid storage element 130 is connected to the electrolytic cell 110 for receiving the acidic stock solution generated by electrolysis, and is also connected to the water supply pipe 120 for receiving raw water. The acid storage element 130 includes a first storage space for containing the acidic liquid generated by mixing the raw water and the acidic stock solution.

[0031] The alkaline storage element 150 includes a second storage space for containing alkaline liquid, which is any alkaline solution that can react with acidic liquid to neutralize the acidic liquid, so as to increase the pH value of the mixed liquid flowing through the water outlet 141 by the alkaline solution with a pH value greater than 7.

[0032] The water outlet pipe 140 is connected to the first storage space of the acid storage element 130, and a water outlet 141 is formed in the water outlet pipe 140. The second storage space of the alkaline storage element 150 is connected to the water outlet pipe 140 through the alkaline pipe 151, thereby realizing the connection between the alkaline liquid and the acidic liquid, so that the alkaline liquid can neutralize the acidic liquid, and further realize the pH value of the mixed liquid flowing through the water outlet 141 can be adjusted by the alkaline liquid.

[0033] The pH detection element 160 is a pH meter, which can be any pH meter in the prior art. The pH detection element 160 acts on the water outlet 141 and is used to detect the pH of the liquid flowing through the water outlet 141, that is, to detect the pH value of the slightly acidic hypochlorous acid water discharged from the water outlet 141, 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.

[0034] The alkaline pipe 151 is provided with an alkaline valve 152 for controlling the flow rate of the alkaline liquid in the alkaline pipe 151. The alkaline valve 152 can adjust the opening and closing degree according to the pH detected by the pH detection element 160 to adjust the flow rate of the alkaline liquid in the alkaline pipe 151, thereby adjusting the content of the mixed liquid alkaline liquid flowing through the water outlet 141. In one embodiment, the alkaline valve 152 is a one-way valve.

[0035] The control component 190 is configured to receive the pH detected by the pH detection component 160 and control the opening and closing degree of the alkaline valve 152 according to the pH, so as to automatically adjust the opening and closing degree of the alkaline valve 152 according to the pH value of the mixed liquid flowing through the water outlet 141, and then adjust the flow rate of the alkaline liquid in the alkaline valve 152 and the content of the alkaline liquid in the mixed liquid flowing through the water outlet 141, so as to achieve the purpose of adjusting the pH value of the mixed liquid flowing through the water outlet 141.

[0036] In one embodiment, the water supply pipe 120 is provided with a water supply valve 121 for controlling the flow rate of raw water in the water supply pipe 120, so as to control the content of raw water in the mixed liquid flowing through the water outlet 141 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 141 is too high, and the flow rate of raw water in the water supply pipe 120 can be reduced by adjusting the water supply valve 121, thereby reducing the content of raw water in the mixed liquid flowing through the water outlet 141; 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 141 is too low, and the flow rate of raw water in the water supply pipe 120 can be increased by adjusting the water supply valve 121, thereby increasing the content of raw water in the mixed liquid flowing through the water outlet 141.

[0037] In one embodiment, the control component 190 is configured to receive the pH detected by the pH detection component 160 and control the opening and closing degree of the water supply valve 121 according to the pH. The water supply valve 121 is controlled by the control component 190 to automatically adjust the opening and closing degree of the water supply valve 121 according to the pH value of the mixed liquid flowing through the water outlet 141, thereby adjusting the flow rate of the raw water in the water supply pipe 120 and the raw water content in the mixed liquid flowing through the water outlet 141, so as to achieve the purpose of adjusting the pH value of the mixed liquid flowing through the water outlet 141.

[0038] In one embodiment, the water supply valve 121 is a one-way valve, which is used to control the flow of raw water to the acid storage element 130. 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 such as unstable water pressure and water volume fluctuations, which cause the pH value of slightly acidic hypochlorous acid water to fluctuate. In some embodiments, the water supply pipe 120 is also provided with a flow meter 122 for detecting the flow of raw water flowing through the water supply pipe 120, so as to monitor the flow of raw water, and combine the adjustment of the flow by the water supply valve 121 to achieve a stable flow of raw water.

[0039] In one embodiment, the slightly acidic hypochlorous water generating device 100 further includes an acid pipe 131, which is connected to the acid storage element 130 and the water outlet pipe 140. The acid pipe 131 is provided with an acid valve 132 for controlling the flow rate of the acid liquid in the acid pipe 131, so as to adjust the flow rate of the acid liquid in the acid pipe 131, and further adjust the content of the mixed liquid acid liquid flowing through the water outlet 141. In one embodiment, the acid valve 132 is a one-way valve.

[0040] In one embodiment, the control component 190 is configured to receive the pH detected by the pH detection component 160 and control the opening and closing degree of the acid valve 132 according to the pH. The acid valve 132 is controlled by the control component 190 to automatically adjust the opening and closing degree of the acid valve 132 according to the pH value of the mixed liquid flowing through the water outlet 141, thereby adjusting the flow rate of the acid liquid in the acid valve 132 and the content of the acid liquid in the mixed liquid flowing through the water outlet 141, so as to achieve the purpose of adjusting the pH value of the mixed liquid flowing through the water outlet 141.

[0041] In the above scheme, by setting the pH detection element 160 at the water outlet 141, the pH of the mixed liquid flowing through the water outlet 141 is obtained, and combined with the alkaline storage element 150 connected to the water outlet pipe 140, the opening and closing degree of the alkaline valve 152 is automatically adjusted according to the pH value of the mixed liquid flowing through the water outlet 141 through the control element 190, and then the flow rate of the alkaline liquid in the alkaline valve 152 and the content of the alkaline liquid in the mixed liquid flowing through the water outlet 141 are adjusted to achieve the purpose of adjusting the pH value of the mixed liquid flowing through the water outlet 141, so as to stabilize the pH value of the slightly acidic hypochlorous acid water.

[0042] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0043] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
