Technical Field

[0001] This application relates to the technical field of swimming pool disinfection equipment, specifically to a sodium hypochlorite generator for swimming pools. Background Technology

[0002] Swimming pool water needs to be disinfected regularly to ensure its hygiene. A sodium hypochlorite generator is a water treatment disinfection and sterilization device that uses sodium chloride solution as a raw material and produces sodium hypochlorite solution through an electrolytic reaction, thereby achieving disinfection of the pool water.

[0003] In some cases, it is necessary to adjust the pH of the sodium hypochlorite solution or add appropriate agents to the solution during disinfection to improve the disinfection effect. However, existing sodium hypochlorite generators are limited in function and cannot adjust the pH or add agents during the preparation of the sodium hypochlorite solution. Utility Model Content

[0036] Example

[0037] See Figure 1 , Figure 2 and Figure 3 This embodiment proposes a sodium hypochlorite generator for swimming pools, including a generator body 100 and a dispensing device 200. The generator body 100 includes an electrolytic plate assembly 110 for electrolyzing brine, and the dispensing device 200 includes a pump 210.

[0038] The pump 210 has an inlet connector 211 connected to a storage container 220, and an outlet connector 212 connected to the inlet end 123 of the generator body 100. The storage container 220 stores a preset solution, which may be an acid or a liquid reagent. When the preset solution is an acid, it can be added to the generator body 100 to adjust the pH; when the preset solution is a liquid reagent, it can be added to the generator body 100.

[0039] Pump 210 is connected to an inlet pipe. One end of the inlet pipe is connected to the inlet connector 211 of pump 210, and the other end is equipped with a one-way filter valve 230, which is immersed in a preset solution. The structure of the one-way filter valve 230 can refer to existing designs and will not be described in detail here.

[0040] Acid or liquid reagent can be added to the generator body 100 via the dispensing device 200, thereby adjusting the pH or adding reagents during the preparation of sodium chlorate solution.

[0041] Specifically, when acid or liquid reagent needs to be added, pump 210 is started. The preset solution in storage container 220 sequentially passes through one-way filter valve 230, inlet pipe, inlet connector 211 of pump 210, outlet connector 212 of pump 210, and inlet end 123 of generator body 100, and finally enters generator body 100. In the above process, one-way filter valve 230 can filter impurities and prevent liquid in inlet pipe from flowing back into storage container 220.

[0042] The outlet connector 212 of the pump 210 is connected to the inlet 123 of the generator body 100 via a three-way valve 240.

[0043] Reference Figure 2 The three-way valve 240 includes a first connection port 241, a second connection port 242, and a third connection port 243 that are interconnected. The first connection port 241 and the second connection port 242 are located at opposite ends of the three-way valve 240, and the third connection port 243 is located on the side of the three-way valve 240. Specifically, the first connection port 241 is used to connect to a liquid circuit, the second connection port 242 is used to connect to the inlet end 123 of the generator body 100, and the third connection port 243 is used to connect to the outlet connector 212 of the pump 210.

[0044] The liquid circuit is used to transport sodium chloride solution. Specifically, the sodium chloride solution is transported to the generator body 100 through a three-way valve 240 via a water pump and corresponding pipelines.

[0045] A one-way valve 250 is installed on the third connection port 243. The pipe on the outlet connector 212 of the pump 210 is connected to the third connection port 243 through the one-way valve 250. After the pump 210 is started, the preset solution in the storage container 220 passes sequentially through the one-way filter valve 230, the inlet pipe, the inlet connector 211 of the pump 210, the outlet connector 212 of the pump 210, the one-way valve 250, the three-way valve 240, and the inlet end 123 of the generator body 100, and finally enters the generator body 100. During this process, the one-way valve 250 acts as a one-way shut-off valve, preventing the liquid in the three-way valve 240 from flowing into the pump 210.

[0046] The check valve 250 is detachably connected to the third connection port 243. Specifically, the check valve 250 and the third connection port 243 can be detachably connected via a threaded connection.

[0047] like Figures 3-5 As shown, the generator body 100 includes a housing 120, and a reaction chamber 121 is provided inside the housing 120, wherein the electrolytic plates of the electrolytic plate assembly 110 are disposed inside the reaction chamber 121.

[0048] The housing 120 includes an opening 122, an inlet 123, and an outlet 124. The opening 122 and the outlet 124 are located at opposite ends along the length of the housing 120, and the inlet 123 is located on the side of the housing 120. An electrolytic plate is inserted into the reaction chamber 121 through the opening 122. The opening 122, the inlet 123, and the outlet 124 are all connected to the reaction chamber 121.

[0049] Compared to the discharge end 124, the inlet end 123 is closer to the opening 122. Along the length of the shell 120, the cross-sectional area of ​​the reaction chamber 121 gradually decreases from the opening 122 to the discharge end 124.

[0050] The above-mentioned structural design has at least the following advantages: it increases the contact area between the sodium chloride solution at the inlet 123 and the electrolytic plate, resulting in more sodium chloride solution in contact with the electrolytic plate and a more concentrated chlorine gas, thereby obtaining a higher concentration of sodium hypochlorite solution; the reaction chamber 121 gradually narrows from the opening 122 to the outlet 124, which can increase the liquid flow rate, making the chlorine gas and sodium hypochlorite solution have a longer range at the outlet 124, thereby increasing the area of ​​the disinfection zone and improving the disinfection efficiency.

[0051] A first connector 125 is detachably provided on the inlet end 123, and a second connector 126 is detachably provided on the outlet end 124. The detachable connection can be achieved by means of a threaded connection.

[0052] The first connector 125 and the second connector 126 are used to connect the corresponding pipes.

[0053] The electrolytic plate assembly 110 includes a plug-in portion 111, with an electrolytic plate disposed on one side of the plug-in portion 111 and a circuit structure disposed on the other side of the plug-in portion 111.

[0054] The connector 111 is inserted into the opening 122, wherein the connector 111 is used to seal the opening 122. Furthermore, a sealing ring may be provided between the connector 111 and the opening 122, thereby improving the sealing effect and preventing liquid in the reaction chamber 121 from flowing onto the circuit structure.

[0055] Reference Figure 3 and Figure 6 The insertion part 111 is provided with an annular flange 112. When the insertion part 111 is inserted into the opening part 122, the bottom surface of the flange 112 abuts against the end face of the opening part 122. After the fixing cover 113 is installed on the housing 120, the fixing cover 113 abuts against the top surface of the flange 112, thereby realizing the installation and fixing of the electrolytic plate assembly 110. The fixing cover 113 is provided with a protective cover 114, which can hide the circuit structure and protect the circuit structure.

[0056] The fixed cover 113 is connected to the housing 120 by means of threaded connection or the like, and the protective cover 114 is connected to the fixed cover 113 by means of snap-fit ​​or the like.

[0057] Pump 210 includes a peristaltic pump. The peristaltic pump can accurately control the amount of preset solution dispensed.

[0058] The dispensing device 200 also includes a central control unit 260 with a built-in control module. The central control unit 260 is electrically connected to the peristaltic pump. The central control unit 260 can send control commands to the pump 210 to control the start and stop of the pump 210, etc.
