[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 mixing assembly 120, a water supply pipe 130 and a flow monitoring component 132. 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 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] 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] The raw water mixed with chlorine to generate hypochlorous acid water is usually directly connected to 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 fluctuating water volume, which causes the pH value of slightly acidic hypochlorous acid water to fluctuate. The flow monitoring component 132 acts on the water supply pipe 130 and is used to detect the flow of raw water flowing through the water supply pipe 130 to monitor the flow of raw water. The flow can be adjusted in combination with the water supply valve 131 to achieve a stable raw water flow, and the acidic liquid and alkaline liquid can also be adjusted according to the flow of raw water. Usually, the pH of raw water is about 7, which is slightly higher than the pH value of slightly acidic hypochlorous acid water. When the average flow of raw water is higher than the required flow range, the raw water content in the mixed liquid flowing through the water outlet 121 is too high, and the pH value of slightly acidic hypochlorous acid water is too high; when the average flow of raw water is lower than the required flow range, the raw water content in the mixed liquid flowing through the water outlet 121 is too low, and the pH value of slightly acidic hypochlorous acid water is too low.

[0031] In one embodiment, the flow monitoring component 132 is configured to detect the flow of raw water flowing through the water supply pipe 130 multiple times per unit time, and calculate the average flow of raw water flowing through the water supply pipe 130 per unit time, so that the obtained average flow of raw water is more accurate, which is convenient for accurately calculating and adjusting the pH value of the mixed liquid flowing through the water outlet 121. Exemplarily, the flow monitoring component 132 can use any flow meter in the prior art and cooperate with a control board with a calculation function to obtain the average flow.

[0032] 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 that when the flow rate of raw water in the water supply pipe 130 fluctuates due to factors such as water pressure, the opening and closing degree of the water supply valve 131 can be adjusted to compensate for the fluctuation of the raw water flow rate caused by factors such as water pressure, without adjusting the opening and closing degree of the water supply valve 131, thereby stabilizing the content of raw water in the mixed liquid flowing through the water outlet 121. For example, without adjusting the opening and closing degree of the water supply valve 131, if the flow monitoring component 132 detects that the average flow rate of raw water per unit time decreases and is lower than the required flow rate range, the water supply valve 131 can be opened to increase the flow rate of raw water in the water supply pipe 130 to the required flow rate range; and when the flow monitoring component 132 detects that the average flow rate of raw water per unit time increases and is higher than the required flow rate range, the water supply valve 131 can be adjusted to decrease the flow rate of raw water in the water supply pipe 130 to the required flow rate range, thereby stabilizing the content of raw water in the mixed liquid flowing through the water outlet 121.

[0033] Combination Figure 3 As shown, in one embodiment, the slightly acidic hypochlorous acid water generating device 100 further includes a control component 190, which is configured to receive an average flow rate detected by the flow monitoring component 132 and control the opening and closing degree of the water supply valve 131 according to the average flow rate. 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 average flow rate detected by the flow monitoring component 132, thereby automatically stabilizing the content of raw water in the mixed liquid flowing through the water outlet 121 and stabilizing the pH value of the slightly acidic hypochlorous acid water.

[0034] 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.

[0035] 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. The acid storage element 160 is used to receive water and the acidic raw 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 raw solution.

[0036] 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.

[0037] 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.

[0038] 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 .

[0039] Since the pH value of the alkaline liquid is greater than 7, the higher the content of the alkaline liquid in the mixed liquid flowing through the water outlet 121, the greater the pH value of the slightly acidic hypochlorous acid water. 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, so as to adjust the flow rate of the alkaline liquid in the alkaline pipe 123, and further adjust the content of the alkaline liquid in the mixed liquid flowing through the water outlet 121.

[0040] In one embodiment, the control component 190 is configured to receive the average flow detected by the flow monitoring component 132 and control the opening and closing degree of the alkaline valve 125 according to the average flow. 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 average flow of the raw water, 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. For example, when the average flow rate of raw water decreases, the raw water content in the mixed liquid flowing through the water outlet 121 is too low, and the pH value of the slightly acidic hypochlorous acid water is too low at this time. The opening degree of the alkaline valve 125 can be increased, thereby increasing the flow rate of the alkaline liquid in the alkaline tube 123 and the content of the alkaline liquid in the mixed liquid flowing through the water outlet 121, so as to achieve the purpose of increasing the pH value of the mixed liquid flowing through the water outlet 121, thereby achieving the stabilization of the pH value of the slightly acidic hypochlorous acid water. On the contrary, when the average flow rate of raw water increases, the raw water content in the mixed liquid flowing through the water outlet 121 is too high, and the pH value of the slightly acidic hypochlorous acid water is too high at this time. At this time, the opening degree of the alkaline valve 125 can be reduced, thereby reducing the flow rate of the alkaline liquid in the alkaline tube 123 and the content of the alkaline liquid in the mixed liquid flowing through the water outlet 121, so as to achieve the purpose of reducing the pH value of the mixed liquid flowing through the water outlet 121, thereby achieving the stabilization of the pH value of the slightly acidic hypochlorous acid water.

[0041] In one embodiment, the control component 190 is configured to receive the average flow detected by the flow monitoring component 132 and control the opening and closing degree of the acid valve 126 according to the average flow. 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 average flow of the raw water, 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. For example, when the average flow rate of raw water decreases, the raw water content in the mixed liquid flowing through the water outlet 121 is too low, and the pH value of the slightly acidic hypochlorous acid water is too low at this time. The opening degree of the acid valve 126 can be reduced to reduce the flow rate of the acidic liquid in the acid pipe 122 and the content of the acidic liquid in the mixed liquid flowing through the water outlet 121, so as to increase the pH value of the mixed liquid flowing through the water outlet 121, thereby achieving a stable pH value of the slightly acidic hypochlorous acid water. On the contrary, when the average flow rate of raw water increases, the raw water content in the mixed liquid flowing through the water outlet 121 is too high, and the pH value of the slightly acidic hypochlorous acid water is too high at this time. At this time, the opening degree of the acid valve 126 can be increased to increase the flow rate of the acidic liquid in the acid valve 126 and the content of the acidic liquid in the mixed liquid flowing through the water outlet 121, so as to reduce the pH value of the mixed liquid flowing through the water outlet 121, thereby achieving a stable pH value of the slightly acidic hypochlorous acid water.

[0042] The slightly acidic hypochlorous acid water generating device 100 provided in the above scheme, by setting a flow monitoring component 132 in the water supply pipe 130, obtains the actual flow rate of raw water in the water supply pipe 130, so as to facilitate knowing the raw water content in the mixed liquid flowing through the water outlet 121 according to the flow rate of raw water, and predicting the pH value change of the slightly acidic hypochlorous acid water caused by the actual flow fluctuation, and then by monitoring the flow rate of raw water, obtains the direction of adjusting the pH value of the slightly acidic hypochlorous acid water, thereby achieving the effect of stabilizing the pH value of the slightly acidic hypochlorous acid water.

[0043] 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.

[0044] 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.
