Description

Technical Field

[0001] This application relates to the field of slightly acidic electrolyzed water preparation, and more specifically, to a cabinet-type slightly acidic electrolyzed water generating device. Background Technology

[0002] The current process flow for slightly acidic electrolyzed water generators is as follows: An electrolyte solution is added to a storage tank, diluted with tap water (after primary filtration) to create an electrolyte solution, which is then stored. During the production of electrolyzed water, the stored electrolyte solution is mixed with tap water and then electrolyzed in the electrolysis device. The resulting electrolyzed water is then stored and used.

[0003] When tap water is supplied directly in this process, the generated electrolyte and the generated electrolyzed water are affected by impurities in the tap water. Furthermore, impurities in tap water are prone to scale formation and blockage in the electrolysis device, which can damage the device. Summary of the Invention

[0004] To overcome the above deficiencies, this application provides a cabinet-type slightly acidic electrolytic water generation device, which aims to improve the problem of electrolysis device damage caused by impurities in tap water.

[0005] This application provides a cabinet-type slightly acidic electrolyzed water generating device, including a cabinet, an electrolyte storage device, an electrolysis device, and an acidic water storage device. The cabinet contains a primary filtration device, a secondary filtration device, and a secondary filtration water supply pump. The output and input ends of the secondary filtration water supply pump are connected to the primary and secondary filtration devices respectively via pure water pipelines. The outlet of the secondary filtration device is connected to the pure water storage device. The electrolyte storage device is installed inside the cabinet and is connected to an electrolyte replenishment pipeline.

[0006] The electrolysis device is installed inside the cabinet. The outlet of the pure water storage device is connected to the inlet of the electrolysis device through a pure water supply pump. The outlet of the electrolyte storage device is connected to the inlet of the electrolysis device through a high-precision flow pump. The acid water storage device is connected to the outlet of the electrolysis device through an acid water pipeline.

[0007] In the above process, the water source is filtered by the primary filtration device and then transported to the secondary filtration device by the secondary filtration water supply pump for further purification to obtain pure water. The pure water is stored in a pure water storage device. The pure water storage device and the electrolyte storage device simultaneously supply pure water and electrolyte to the electrolysis device, so that the pure water and electrolyte generate slightly acidic water in the electrolysis device. The slightly acidic water generated is stored by the acid water storage device for later use.

[0008] In one specific implementation, the outlet of the primary filtration device is connected to the input end of the secondary filtration water supply pump through a portion of the pure water pipeline, and the inlet of the secondary filtration device is connected to the output end of the secondary filtration water supply pump through another portion of the pure water pipeline.

[0009] In the above process, the pure water pipeline and the secondary filtration water supply pump can transport the water that has been preliminarily filtered by the primary filtration device to the secondary filtration device for further filtration and purification.

[0010] In one specific implementation, the pure water pipeline is equipped with a pressure detection device.

[0011] In the above implementation process, the pressure detection device adopts a pipe pressure monitoring system and adjusts the pressure inside the pure water pipeline in real time through pressure feedback values ​​to ensure that the pressure and flow rate inside the pipe meet the process requirements during production.

[0012] In one specific implementation, the secondary filtration water supply pump and the pure water storage device are connected by a pipeline, and the pipeline is equipped with a TDS detection device and a flow valve.

[0013] In the above implementation process, a TDS detection device is added to monitor the working status of the water filtration process system in real time to ensure the stability of the overall process. The setting of the flow valve ensures the stability of the water electrolysis process and can also be used to record data and adjust parameters.

[0014] In one specific implementation, the cabinet is equipped with an electrolyte replenishment pump, and the output end of the electrolyte replenishment pump is connected to the electrolyte storage device through the electrolyte replenishment pipeline.

[0015] In the above process, when the liquid level in the electrolyte storage device is too low and electrolyte needs to be replenished, external electrolyte can be added to the electrolyte storage device through an electrolyte replenishment pump.

[0016] In one specific implementation, a micro-acid water supply pump is installed inside the cabinet, and the input end of the micro-acid water supply pump is connected to the acid water storage device.

[0017] In the above implementation process, the installation of the slightly acidic water supply pump ensures that when slightly acidic electrolyzed water is supplied, it can provide a stable pressure and flow rate of acidic water to the terminal for use, without the drawbacks of flow interruption or splashing.

[0018] In one specific implementation, the pure water storage device, the electrolyte storage device, and the acid water storage device are all equipped with level switches.

[0019] In the above implementation process, a liquid level switch is set up to facilitate real-time monitoring of the liquid level content of the pure water storage device, the electrolyte storage device, and the acid water storage device.

[0020] In one specific implementation, the acid water pipeline consists of at least two corrosion-resistant pipes.

[0021] In the above process, corrosion-resistant pipes are used to construct the acid water pipeline, thereby improving the corrosion resistance of the acid water pipeline and extending its service life.

[0022] In one specific implementation, an overflow pipeline is also included, and the pure water storage device, the electrolyte storage device, and the acid water storage device are all connected to the overflow pipeline.

[0023] In the above process, when there is too much solution in the pure water storage device, the electrolyte storage device, and the acid water storage device and it is about to overflow, the excess solution is directly discharged to the outside of the cabinet through the overflow pipe.

[0024] In one specific implementation, the outlet of the overflow pipe extends to the outside of the cabinet.

[0025] In the above implementation process, the overflow pipe facilitates the discharge of excess solution to the outside of the cabinet.

[0026] In one specific implementation, the input end of the pure water supply pump is connected to the pure water storage device via a pure water supply pipeline, and one end of the pure water supply pipeline is inserted into the pure water storage device. A pusher plate is slidably installed inside the pure water storage device, and a sealing strip is fixed to the side wall of the pusher plate. The sealing strip is sealed and fitted to the inner wall of the pure water storage device. A motor is installed inside the pure water storage device, and the output shaft of the motor is driven by a lead screw. A sliding sleeve is threaded onto the body of the lead screw, and one end of the sliding sleeve is fixedly connected to the pusher plate.

[0027] In the above process, when the level of pure water stored in the pure water storage device is lower than the port of the pure water supply pipeline, the motor is started, which drives the lead screw to rotate. The sliding sleeve threaded on the surface of the lead screw pushes the pusher plate towards the end of the pure water supply pipeline, reducing the distance between the pusher plate and the end of the pure water supply pipeline. As a result, the level of pure water between the pusher plate and the pure water supply pipeline rises. Once the level of pure water is higher than the end of the pure water supply pipeline, pure water can be output through the pure water supply pipeline. This ensures a stable supply of pure water to the electrolysis device when the pure water capacity in the pure water storage device is low.

[0028] In one specific implementation, a movable horizontal plate is installed at the top of the water pusher plate, and a fixed horizontal plate is provided inside the pure water storage device. A first sealing gasket is installed on the upper end face of the movable horizontal plate, and a second sealing gasket is installed on the lower end face of the fixed horizontal plate. Both the upper end face of the first sealing gasket and the lower end face of the second sealing gasket are provided with protrusions at intervals. The protrusions on the upper end face of the first sealing gasket and the protrusions on the lower end face of the second sealing gasket interlock and seal with each other.

[0029] In the above implementation process, the installation of sealing strips can improve the sealing between the push plate and the inner wall of the pure water storage device, and make it easier for the push plate to push the pure water to the end of the pure water supply pipeline. The installation of the first sealing gasket and the second sealing gasket can improve the sealing between the moving horizontal plate and the fixed horizontal plate, and can effectively prevent pure water from flowing into the area below the moving horizontal plate and the fixed horizontal plate.

[0030] In one specific implementation, the top end of the sealing strip is bent and fixedly connected to the side wall of the moving cross plate.

[0031] In the above process, the sealing strip can improve the sealing between the moving cross plate and the inner wall of the pure water storage device.

[0032] In one specific implementation, a guide sleeve is provided inside the pure water storage device, and a sliding rod is fixed to the side wall of the pusher plate, with one end of the sliding rod slidably inserted into the inside of the guide sleeve.

[0033] In the above implementation process, during the movement of the pusher plate, the guide sleeve can make the movement of the pusher plate more stable by restricting the movement direction of the slide rod.

[0034] In one specific implementation, the pure water storage device is connected to an overflow pipe, one end of which extends into the pure water storage device and the other end extends to the outside of the cabinet. A limiting seat is connected above one end of the overflow pipe. A blocking block is slidably installed inside the overflow pipe, and an elastic element is installed between the top of the blocking block and the limiting seat. A connecting rod is hinged to the surface of the sliding sleeve, and a push rod is hinged to one end of the connecting rod. The top of the push rod slides through the second sealing gasket and the fixed horizontal plate in sequence, and the push rod is located directly below the blocking block. A groove corresponding to the push rod is opened on the lower end face of the overflow pipe.

[0035] In the above process, when there is too much pure water in the pure water storage device, the motor is started. The motor drives the lead screw to rotate, causing the sliding sleeve threaded on the surface of the lead screw to move towards the push rod. The connecting rod hinged on the surface of the sliding sleeve will push the push rod, causing the push rod to rise. The upward-moving push rod will contact the block and push the block into the limit seat. The block will no longer block the overflow pipe, and the pure water in the pure water storage device can be discharged into the outside of the cabinet through the overflow pipe until the liquid level of the pure water in the pure water storage device is lower than the overflow pipe, which can effectively prevent pure water from overflowing into the cabinet.

[0036] Furthermore, when the liquid level of the pure water stored in the pure water storage device is lower than the port of the pure water supply pipeline, the motor drives the lead screw to rotate, causing the sliding sleeve threaded on the surface of the lead screw to move away from the push rod (i.e., the sliding sleeve pushes the push plate to move towards the end of the pure water supply pipeline). Under the pull of the connecting rod, the push rod descends and separates from the block. With the support of the elastic element, the block moves from the limit seat into the overflow pipe, which can seal the overflow pipe.

[0037] Understandably, this motor is a servo motor, and its output shaft can rotate in both directions.

[0038] In one specific implementation, a guide rod is installed at the top of the block, and the top of the guide rod slides through the limiting seat, and the second sealing gasket is sealed and fitted with the push rod.

[0039] In the above implementation process, the limiting seat restricts the movement of the block by limiting the movement of the guide rod, thereby making the movement of the block more stable.

[0040] Beneficial effects: This application provides a cabinet-type slightly acidic electrolyzed water generating device, which purifies tap water through a primary filtration device and a secondary filtration device, improves the quality of the supplied water, and directly combines the purified water with the electrolyzing agent, simplifying the process flow, improving productivity, and effectively avoiding scaling and blockage in the electrolysis equipment, greatly reducing the possibility of damage to the electrolysis device.

[0041] When using pure water electrolysis to prepare slightly acidic water, the pure water stored in the container needs to be transported to the electrolysis equipment through a pipeline. After use, the pure water level in the container will gradually decrease. When the pure water level is lower than the pipeline, pure water cannot be transported. Furthermore, the container for storing pure water is not easy to adjust its internal volume, which is not conducive to raising the pure water level and thus hinders the transport of pure water.

[0042] When the level of pure water stored in the pure water storage device is lower than the port of the pure water supply pipeline, the motor is started, causing the motor to drive the lead screw to rotate. This causes the sliding sleeve, which is threaded onto the surface of the lead screw, to push the pusher plate towards the end of the pure water supply pipeline, reducing the distance between the pusher plate and the end of the pure water supply pipeline. As a result, the level of pure water between the pusher plate and the pure water supply pipeline rises. Once the level of pure water is higher than the end of the pure water supply pipeline, pure water can be output through the pure water supply pipeline. This ensures a stable supply of pure water to the electrolysis device even when the pure water capacity in the pure water storage device is low.

[0043] In addition, the installation of sealing strips can improve the sealing between the push plate and the inner wall of the pure water storage device, making it easier for the push plate to push the pure water to the end of the pure water supply pipeline. The installation of the first sealing gasket and the second sealing gasket can improve the sealing between the moving horizontal plate and the fixed horizontal plate, effectively preventing pure water from flowing into the area below the moving horizontal plate and the fixed horizontal plate.

[0044] The generator that produces slightly acidic water using pure water and an electrolyte stores pure water in a container inside the generator during use, and then draws it out for use. However, when there is too much pure water in the container, it is inconvenient to drain the pure water out of the generator, and it will overflow into the generator, causing damage to the generator.

[0045] When there is too much pure water in the pure water storage device, the motor is started. The motor drives the lead screw to rotate, causing the sliding sleeve threaded on the surface of the lead screw to move towards the push rod. The connecting rod hinged on the surface of the sliding sleeve will push the push rod, causing the push rod to rise. The upward-moving push rod will contact the block and push the block into the limit seat. The block will no longer block the overflow pipe, and the pure water in the pure water storage device can be discharged into the outside of the cabinet through the overflow pipe until the liquid level of the pure water in the pure water storage device is lower than the overflow pipe, which can effectively prevent pure water from overflowing into the cabinet.

[0046] When the level of pure water stored in the pure water storage device is lower than the port of the pure water supply pipeline, the motor drives the lead screw to rotate, causing the sliding sleeve with the threaded sleeve on the surface of the lead screw to move away from the push rod. Under the pull of the connecting rod, the push rod descends and separates from the block. With the support of the elastic element, the block moves from the limit seat into the overflow pipe, which can seal the overflow pipe. Attached Figure Description

Detailed Implementation

[0057] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.

[0058] Please see Figures 1-8This application provides a cabinet-type slightly acidic electrolyzed water generating device, including a cabinet 100, an electrolyte storage device 200, an electrolysis device 300, and an acid water storage device 400. The electrolyte storage device 200, the electrolysis device 300, and the acid water storage device 400 are all housed within the cabinet 100.

[0059] The cabinet 100 is equipped with a primary filtration device 110, a secondary filtration device 120 and a secondary filtration water supply pump 130. The output and input ends of the secondary filtration water supply pump 130 are connected to the primary filtration device 110 and the secondary filtration device 120 respectively through a pure water pipeline 140. The outlet of the secondary filtration device 120 is connected to a pure water storage device 150.

[0060] An electrolyte storage device 200 is installed inside a cabinet 100, and the electrolyte storage device 200 is connected to an electrolyte replenishment pipeline 210.

[0061] The electrolysis device 300 is installed inside the cabinet 100. The outlet of the pure water storage device 150 is connected to the inlet of the electrolysis device 300 through the pure water supply pump 160. The outlet of the electrolyte storage device 200 is connected to the inlet of the electrolysis device 300 through the high-precision flow pump 220.

[0062] The acid water storage device 400 is connected to the outlet of the electrolysis device 300 through the acid water pipeline 410.

[0063] In the above process, the water source is filtered by the primary filtration device 110 and then transported to the secondary filtration device 120 by the secondary filtration water supply pump 130 for further purification to obtain pure water. The pure water is stored in the pure water storage device 150. The pure water storage device 150 and the electrolyte storage device 200 simultaneously supply pure water and electrolyte to the electrolysis device 300, so that the pure water and electrolyte generate slightly acidic water in the electrolysis device 300. The generated slightly acidic water is stored by the acid water storage device 400 for later use.

[0064] In one specific implementation, the outlet of the primary filtration device 110 is connected to the input of the secondary filtration water supply pump 130 through a portion of the pure water pipeline 140, and the inlet of the secondary filtration device 120 is connected to the output of the secondary filtration water supply pump 130 through another portion of the pure water pipeline 140.

[0065] In the above process, the pure water pipeline 140 and the secondary filtration water supply pump 130 can transport the water that has been preliminarily filtered by the primary filtration device 110 to the secondary filtration device 120 for further filtration and purification.

[0066] In one specific implementation scheme, a pressure detection device is installed on the pure water pipeline 140.

[0067] In the above implementation process, the pressure detection device adopts a pipe pressure monitoring system and adjusts the pressure inside the pure water pipeline 140 in real time through pressure feedback value to ensure that the pressure and flow rate inside the pipe meet the process requirements during production.

[0068] In one specific implementation, the secondary filtration water supply pump 130 and the pure water storage device 150 are connected by a pipeline, and the pipeline is connected to a TDS detection device 170 and a flow valve.

[0069] In the above implementation process, a TDS detection device 170 is added to monitor the working status of the water filtration process system in real time to ensure the stability of the overall process. The setting of the flow valve ensures the stability of the water electrolysis process and can also be used to record data and adjust parameters.

[0070] In one specific implementation, the cabinet 100 is equipped with an electrolyte replenishment pump 230, and the output end of the electrolyte replenishment pump 230 is connected to the electrolyte storage device 200 through the electrolyte replenishment pipeline 210.

[0071] In the above process, when the liquid level in the electrolyte storage device 200 is too low and electrolyte needs to be replenished, external electrolyte can be replenished into the electrolyte storage device 200 by the electrolyte replenishment pump 230.

[0072] In one specific implementation, a micro-acid water supply pump 420 is installed inside the cabinet 100, and the input end of the micro-acid water supply pump 420 is connected to the acid water storage device 400.

[0073] In the above implementation process, the setting of the slightly acidic water supply pump 420 ensures that when slightly acidic electrolyzed water is supplied, it can provide acidic water with stable pressure and flow rate to the terminal for use, and there will be no drawbacks such as flow interruption or splashing.

[0074] In one specific implementation, the pure water storage device 150, the electrolyte storage device 200, and the acid water storage device 400 are all equipped with level switches.

[0075] In the above implementation process, a liquid level switch is set up to facilitate real-time monitoring of the liquid level content of the pure water storage device 150, the electrolyte storage device 200, and the acid water storage device 400.

[0076] In one specific implementation, the acid water pipeline 410 consists of at least two corrosion-resistant pipes.

[0077] In the above implementation process, corrosion-resistant pipes are used to construct the acid water pipeline 410, thereby improving the corrosion resistance of the acid water pipeline 410 and extending its service life.

[0078] In one specific implementation, an overflow pipe 430 is also included, and the pure water storage device 150, the electrolyte storage device 200 and the acid water storage device 400 are all connected to the overflow pipe 430.

[0079] In the above process, when there is too much solution in the pure water storage device 150, the electrolyte storage device 200 and the acid water storage device 400 and it is about to overflow, the excess solution is directly discharged to the outside of the cabinet 100 through the overflow pipe 430.

[0080] In one specific implementation, the outlet of the overflow pipe 430 extends to the outside of the cabinet 100.

[0081] In the above implementation process, the overflow pipe 430 facilitates the discharge of excess solution to the outside of the cabinet 100.

[0082] When using pure water electrolysis to prepare slightly acidic water, the pure water stored in the container needs to be transported to the electrolysis equipment through a pipeline. After use, the pure water level in the container will gradually decrease. When the pure water level is lower than the pipeline, pure water cannot be transported. Furthermore, the container for storing pure water is not easy to adjust its internal volume, which is not conducive to raising the pure water level and thus hinders the transport of pure water.

[0083] In one specific implementation, the input end of the pure water supply pump 160 is connected to the pure water storage device 150 through the pure water supply pipeline 161, and one end of the pure water supply pipeline 161 is inserted into the pure water storage device 150. A pusher plate 500 is slidably installed inside the pure water storage device 150. A sealing strip 510 is fixed to the side wall of the pusher plate 500, and the sealing strip 510 is sealed and fitted to the inner wall of the pure water storage device 150. A motor 520 is installed inside the pure water storage device 150, and the output shaft of the motor 520 is driven and connected to a lead screw 530. A sliding sleeve 540 is threaded onto the body of the lead screw 530, and one end of the sliding sleeve 540 is fixedly connected to the pusher plate 500.

[0084] In the above implementation process, when the liquid level of pure water stored in the pure water storage device 150 is lower than the port of the pure water supply pipeline 161, the motor 520 is started, causing the motor 520 to drive the lead screw 530 to rotate. This causes the sliding sleeve 540, which is threaded onto the surface of the lead screw 530, to push the pusher plate 500 towards the end of the pure water supply pipeline 161, reducing the distance between the pusher plate 500 and the end of the pure water supply pipeline 161. As a result, the liquid level of pure water between the pusher plate 500 and the pure water supply pipeline 161 will rise. Once the liquid level of pure water is higher than the end of the pure water supply pipeline 161, pure water can be output through the pure water supply pipeline 161, ensuring a stable supply of pure water to the electrolysis device 300 when the pure water capacity in the pure water storage device 150 is low.

[0085] In one specific implementation, a movable horizontal plate 550 is installed at the top of the push plate 500, and a fixed horizontal plate 560 is provided inside the pure water storage device 150. A first sealing gasket 551 is installed on the upper end surface of the movable horizontal plate 550, and a second sealing gasket 561 is installed on the lower end surface of the fixed horizontal plate 560. Both the upper end surface of the first sealing gasket 551 and the lower end surface of the second sealing gasket 561 are provided with protrusions at intervals. The protrusions on the upper end surface of the first sealing gasket 551 and the protrusions on the lower end surface of the second sealing gasket 561 interlock and seal with each other.

[0086] In the above implementation process, the sealing strip 510 can improve the sealing between the push plate 500 and the inner wall of the pure water storage device 150, and make it easier for the push plate 500 to push the pure water to the end of the pure water supply pipeline 161. The first sealing gasket 551 and the second sealing gasket 561 can improve the sealing between the moving horizontal plate 550 and the fixed horizontal plate 560, and can effectively prevent pure water from flowing into the area below the moving horizontal plate 550 and the fixed horizontal plate 560.

[0087] In one specific implementation, the top end of the sealing strip 510 is bent and fixedly connected to the side wall of the moving cross plate 550.

[0088] In the above process, the sealing strip 510 can improve the sealing between the moving cross plate 550 and the inner wall of the pure water storage device 150.

[0089] In one specific implementation, a guide sleeve 151 is provided inside the pure water storage device 150, and a slide rod 570 is fixed to the side wall of the push plate 500, with one end of the slide rod 570 slidably inserted into the inside of the guide sleeve 151.

[0090] In the above implementation process, during the movement of the push plate 500, the guide sleeve 151 can make the push plate 500 move more stably by limiting the movement direction of the slide rod 570.

[0091] The generator that produces slightly acidic water using pure water and an electrolyte stores pure water in a container inside the generator during use, and then draws it out for use. However, when there is too much pure water in the container, it is inconvenient to drain the pure water out of the generator, and it will overflow into the generator, causing damage to the generator.

[0092] In one specific implementation, the pure water storage device 150 is connected to an overflow pipe 600. One end of the overflow pipe 600 extends into the pure water storage device 150, and the other end extends to the outside of the cabinet 100. A limiting seat 610 is connected above one end of the overflow pipe 600. A blocking block 620 is slidably installed inside the overflow pipe 600, and an elastic element 630 is installed between the top of the blocking block 620 and the limiting seat 610. A connecting rod 640 is hinged to the surface of the sliding sleeve 540, and a push rod 650 is hinged to one end of the connecting rod 640. The top of the push rod 650 slides through the second sealing gasket 561 and the fixed horizontal plate 560 in sequence, and the push rod 650 is located directly below the blocking block 620. A groove corresponding to the push rod 650 is opened on the lower end face of the overflow pipe 600.

[0093] In the above implementation process, when there is too much pure water in the pure water storage device 150, the motor 520 is started. The motor 520 drives the lead screw 530 to rotate, causing the sliding sleeve 540 threaded on the surface of the lead screw 530 to move towards the push rod 650. The connecting rod 640 hinged on the surface of the sliding sleeve 540 pushes the push rod 650, causing the push rod 650 to rise. The upward-moving push rod 650 will contact the block 620 and push the block 620 into the limit seat 610. The block 620 will no longer block the overflow pipe 600, and the pure water in the pure water storage device 150 can be discharged into the outside of the cabinet 100 through the overflow pipe 600 until the liquid level of the pure water in the pure water storage device 150 is lower than the overflow pipe 600, which can effectively prevent pure water from overflowing into the cabinet 100.

[0094] Furthermore, when the liquid level of the pure water stored in the pure water storage device 150 is lower than the port of the pure water supply pipeline 161, the motor 520 drives the lead screw 530 to rotate, causing the sliding sleeve 540 threaded on the surface of the lead screw 530 to move away from the push rod 650 (i.e., the sliding sleeve 540 pushes the push plate 500 to move towards the end of the pure water supply pipeline 161). Under the pull of the connecting rod 640, the push rod 650 descends and separates from the block 620. Under the support of the elastic element 630, the block 620 moves from the limiting seat 610 into the overflow pipe 600, which can seal the overflow pipe 600.

[0095] Understandably, the motor 520 is a servo motor, and the output shaft of the motor 520 can rotate in both directions, while the elastic element 630 is a spring.

[0096] In one specific implementation, a guide rod 621 is installed at the top of the block 620, and the top of the guide rod 621 slides through the limiting seat 610, and the second sealing gasket 561 is sealed and fitted with the push rod 650.

[0097] In the above implementation process, the limiting seat 610 restricts the movement of the guide rod 621, thereby restricting the movement of the block 620 and making the movement of the block 620 more stable.

[0098] Specifically, in use, the cabinet-type slightly acidic electrolyzed water generator delivers external water (such as tap water from the municipal water supply) to the primary filtration device 110. After being filtered by the primary filtration device 110, the water is then delivered by the secondary filtration water supply pump 130 to the secondary filtration device 120 for further purification to obtain pure water. The pure water is stored in the pure water storage device 150. The pure water storage device 150 and the electrolyte storage device 200 simultaneously supply pure water and electrolyte to the electrolysis device 300, causing the pure water and electrolyte to generate slightly acidic water in the electrolysis device 300. The generated slightly acidic water is then stored in the acid water storage device 400 for later use.
