Description

Technical Field

[0001] This invention relates to the field of washing equipment technology, and specifically provides a washing device. Background Technology

[0002] Current washing machines use a water electrolysis technology to achieve sterilization and disinfection by mixing ordinary water with a treatment agent and then introducing the mixture into an electrolysis device. This innovative approach significantly improves washing performance. The core of this technology lies in the fact that the active oxygen species (such as hydroxyl radicals and ozone) generated during electrolysis oxidize the inert components in the treatment agent, transforming them into a more reactive form. The microbubbles (hydrogen and oxygen) generated during electrolysis promote the uniform dispersion of the treatment agent in the water, preventing excessively high local concentrations or clumping.

[0003] However, this technology has also revealed some problems that cannot be ignored during its application. The chemical properties of the treatment agent during the electrolysis process may lead to corrosion of the electrode materials, shortening the service life of the electrolysis device and increasing maintenance costs. More seriously, some components in the treatment agent are prone to forming precipitates under electrolysis conditions. These precipitates gradually accumulate on the electrode surface, forming scale, which not only hinders the full progress of the electrolysis reaction but also greatly reduces the electrolysis efficiency and affects the sterilization and disinfection effect.

[0004] In summary, the electrolysis efficiency of existing washing machines, which mix water and treatment agents before introducing them into the electrolysis device, decreases over time.

[0005] Accordingly, a new technical solution is needed in this field to solve the above problems. Summary of the Invention

[0037] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the invention and are not intended to limit the scope of protection of the invention. Those skilled in the art can make adjustments as needed to adapt to specific applications.

[0038] It should be noted that in the description of this invention, terms such as "upper," "lower," "left," and "right," indicating directional or positional relationships, are based on the directional or positional relationships shown in the accompanying drawings. These are merely for ease of description and do not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation; therefore, they should not be construed as limitations on this invention. Furthermore, the terms "first," "second," "third," and "fourth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0039] Furthermore, it should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "connected" should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0040] See Figure 4 ,like Figure 4 As shown, the washing equipment includes a housing 1 and a washing drum 7 installed inside the housing 1. The washing drum 7 includes an outer drum 71 and an inner drum 72 fitted inside the outer drum 71. The water inlet pipe 3, electrolysis device 4, treatment agent device 5, dispensing pipe 6, and outer drum 71 are connected in sequence. A water inlet valve 2 is installed on the water inlet pipe 3 to control the opening and closing of the water inlet. By using electrolyzed water to enter the treatment agent device 5, the cleaning and disinfection effect of the treatment agent in the treatment agent device 5 can be enhanced. Moreover, the gas generated during electrolysis also enters the treatment agent with the water flow. The bubbles can increase the contact area between the detergent and the stains, making the cleaning more effective.

[0041] The treatment agent can be detergent, fabric softener, etc., and the washing equipment can be a front-loading washing machine, a top-loading washing machine, a washer-dryer combo, or other types of washing equipment. Those skilled in the art can set it according to the actual situation.

[0042] The present invention connects an electrolysis device 4, a treatment agent device 5, and a washing drum 7 in sequence. After water enters the electrolysis device 4 and is electrolyzed, it enters the treatment agent device 5, and then the mixed treatment agent enters the washing drum 7. This can ensure that the electrolyzed water and the treatment agent are mixed in advance, avoid the treatment agent from corroding the electrodes in the electrolysis environment, and also prevent the precipitates generated by the treatment agent from adhering to the electrodes.

[0043] See next. Figure 4 and 5 The treatment agent device 5 includes a first box 51 and a second box 52, which is installed inside the first box 51 by a pull-out mechanism. The second box 52 is used to store the treatment agent, and the treatment agent in the second box 52 can be fed into the first box 51. The first box 51 is provided with a first liquid outlet and a second liquid outlet. The first liquid outlet is connected to the electrolysis device 4, and the second liquid outlet is connected to the washing drum 7. Specifically, the first liquid outlet is located inside the insertion pipe 511 and is connected to the inside of the first box 51. The second liquid outlet is located below the first box 51 and is connected to the dispensing pipe 6. The electrolysis device 4 has a water outlet pipe, which is a second pipe 404 or... Figure 3 The third pipe 421, the water outlet pipe is inserted into the first liquid port, that is, into the insertion pipe 511, and the water outlet end of the water outlet pipe is located above the second box 52, such as Figure 5 As shown, the direction perpendicular to the paper and outward is upward. The front end of the water outlet pipe extends forward to the top of the second box 52 to send electrolyzed water into the second box 52 to mix with the treatment agent inside the second box 52. The second box 52 is provided with a siphon structure (not shown in the figure). The siphon structure includes a siphon tube and a siphon cap sleeved on the outside of the siphon tube. The bottom of the siphon tube is connected to the first box 51. When water is introduced, the water after the electrolyzed water and the treatment agent are mixed flows into the first box 51 through the siphon structure, and then enters the washing drum 7 through the dispensing pipe 6.

[0044] Continue reading Figure 5 The electrolysis device 4 is provided with a first fixing part 434, and the first housing 51 is provided with a second fixing part 512. The electrolysis device 4 and the first housing 51 are connected through the first fixing part 434 and the second fixing part 512. Specifically, the first fixing part 434 is provided with a first fixing hole, and the second fixing part 512 is provided with a second fixing hole. The fastening bolt 416 passes through the first fixing hole and the second fixing hole to fix the electrolysis device 4 to the first housing 51.

[0045] The first fixing part 434 may be a columnar structure, and the second fixing part 512 may be a matching fixing block or fixing post. In some other embodiments, the first fixing part 434 may be a ring-shaped structure that surrounds the insertion pipe 511, and the second fixing part 512 may also be a ring-shaped structure.

[0046] To improve sealing, sealing rings are provided on the inside of the insertion pipe 511 and the outside of the outlet pipe (second pipe 404 or third pipe 421).

[0047] exist Figure 5 In the middle, the water inlet pipe 3 is the first water inlet pipe 31. One end of the first water inlet pipe 31 is sleeved on the outside of the first pipe 403 and fastened by a clamp. The other end of the first water inlet pipe 31 is sleeved on the water inlet valve 2 and fixed by a clamp.

[0048] Continue reading Figure 5 The cross-sectional area of ​​the second box 52 is smaller than that of the first box 51, and the upper part of the second box 52 is an open structure. When the water inflow is too large, the water overflows from the upper part of the second box 52 into the first box 51.

[0049] See next. Figure 6 The second connection method between the electrolysis device 4 and the treatment agent device 5, and Figure 5 The only difference is that the insertion pipe 511 is inserted into the outlet pipe (second pipe 404 or third pipe 421), and a sealing ring is provided on the inner side of the insertion pipe 511 and the outer side of the outlet pipe. The rest of the structure and connection method are the same, and will not be described in detail here.

[0050] See next. Figure 7 In the second connection method between the electrolysis device 4 and the treatment agent device 5, the water inlet pipe 3 includes a first water inlet pipe 31 and a second water inlet pipe 32. One end of the first water inlet pipe 31 is sleeved on the outside of the first pipe 403 and fastened by a clamp. The other end of the first water inlet pipe 31 is sleeved on the water inlet valve 2 and fixed by a clamp. One end of the second water inlet pipe 32 is sleeved on the outside of the insertion pipe 511 and fastened by a clamp. The other end of the second water inlet pipe 32 is sleeved on the outside of the water outlet pipe (second pipe 404 or third pipe 421) of the electrolysis device 4 and fastened by a clamp.

[0051] exist Figure 6 or Figure 7 In the connection method described, the electrolyzed water directly enters the first container 51 and does not enter the second container 52. A dispensing pump can be installed at the bottom of the second container 52 to pump the treatment agent from the second container 52 into the first container 51, allowing the treatment agent to mix with the electrolyzed water before entering the washing drum 7 through the dispensing pipe 6. Alternatively, a solenoid valve can be installed at the bottom of the second container 52 to control its opening, allowing the treatment agent to automatically flow into the second container 52 for dispensing. When the valve is closed, the treatment agent can be stored.

[0052] The second box 52 can be installed inside the first box 51 by being pulled out. The second box 52 can be pulled out and the treatment agent can be injected into the second box 52. Alternatively, it can be fixed inside the first box 51. An injection port is provided on the top of the first box 51 and the top of the box 1, and a cover that can be rotated to close the injection port. The treatment agent can be injected into the second box 52 by opening the injection port.

[0053] See next. Figure 1 and Figure 2 ,like Figure 1 and 2 As shown, the electrolysis device 4 of the first preferred embodiment of the present invention includes a first housing 401 and a second housing 402. The first housing 401 and the second housing 402 are connected to form a first cavity 409. A first electrolysis plate 406, a first diaphragm 408 and a second electrolysis plate 407 are arranged in parallel in the first cavity 409. A first water inlet 432 is provided on the first housing 401 and a second water inlet 405 is provided on the second housing 402. A first groove 410 is formed on the second housing 402. The first diaphragm 408 and the first electrolysis plate 406 are located in the first groove 410. The second electrolysis plate 407 covers the first groove 410. The outer edge of the first groove 410 is a first step portion 411. After the second electrolysis plate 407 is fixedly connected to the first step portion 411, it abuts against the first diaphragm 408 to fix the first electrolysis plate 406 and the first diaphragm 408.

[0054] like Figure 2 As shown, the first electrolytic plate 406 and the first diaphragm 408 are placed side by side in the first groove 410 from right to left. When the second electrolytic plate 407 is fixed to the first step portion 411, the first diaphragm 408 and the first electrolytic plate 406 are pressed to the right, and the first electrolytic plate 406 and the right inner wall of the second housing 402 abut against each other, thereby fixing the first electrolytic plate 406 and the first diaphragm 408.

[0055] The present invention places the first electrolytic plate 406 and the first diaphragm 408 in the first groove 410, and only needs to fix the second electrolytic plate 407 on the stepped portion to achieve complete fixation of the first electrolytic plate 406, the second electrolytic plate 407 and the first diaphragm 408 without separate fixation, saving installation steps and making disassembly and assembly convenient.

[0056] It should be noted that the present invention does not impose any limitation on the number of the first electrolytic plate 406 and the second electrolytic plate 407, such as Figure 2 As shown, there are two first electrolytic plates 406 arranged side by side, and one second electrolytic plate 407. However, this is not a limitation. Those skilled in the art can set the specific number of the first electrolytic plates 406 and the second electrolytic plates 407 according to the actual situation.

[0057] Furthermore, the first electrolytic plate 406 and the second electrolytic plate 407 of the present invention have the same structure, both including a substrate and a boron-doped diamond film disposed on the substrate, that is, a boron-doped diamond film is coated on a conductive substrate. The substrate can be a metallic material or other conductive materials, such as... Figure 2 As shown, a first conductive component 414 and a second conductive component 415 are pre-embedded in the second housing 402. During the manufacturing of the second housing 402, the first conductive component 414 and the second conductive component 415 are pre-molded in the mold. The first conductive component 414 is connected to the first electrolytic plate 406, and the second conductive component 415 is connected to the second electrolytic plate 407. The first conductive component 414 is connected to the positive terminal of the power supply, and the second conductive component 415 is connected to the negative terminal of the power supply.

[0058] In other embodiments, the first conductive member 414 is connected to the negative terminal of the power supply, and the second conductive member 415 is connected to the positive terminal of the power supply.

[0059] In other embodiments, one of the first electrolytic plate 406 and the second electrolytic plate 407 comprises a substrate and a boron-doped diamond film disposed on the substrate. The electrolytic plate having the boron-doped diamond film can be connected to the positive terminal of a power supply.

[0060] The first conductive component 414 and the second conductive component 415 may be the same or different. They may be conductive sheets, conductive wires, or other conductive structures. Those skilled in the art can set them according to the actual situation.

[0061] Furthermore, the first conductive member 414 pre-embedded in the second housing 402 is located in the first groove 410. When the first electrolytic plate 406 is placed in the first groove 410, it can contact the first conductive member 414. The first conductive member 414 extends into the first groove 410, and its extended part is embedded in the left inner wall of the second housing 402. This will not hinder the installation of the first electrolytic plate 406, and can also ensure a good connection between the first electrolytic plate 406 and the first conductive member 414. The pre-embedded second conductive member 415 is located on the left side of the first groove 410 and abuts against the left side wall of the first step portion 411. Both the first conductive member 414 and the second conductive member 415 are partially located inside the second housing 402 and partially located outside the second housing 402.

[0062] Furthermore, Figure 2The upper ends of the two first electrolytic plates 406 are fixed by fastening screws. The fastening screws pass through the two first electrolytic plates 406 and the first conductive member 414 and extend into the inner wall of the second housing 402. This not only improves the stability of the first electrolytic plates 406, but also improves the tightness of the connection between the first electrolytic plates 406 and the first conductive member 414. The fastening screws pass through the second electrolytic plate 407 and extend into the first step portion 411, fixing the lower part of the second electrolytic plate 407. Since the first electrolytic plates 406 and the first diaphragm 408 are located in the first groove 410, the upper ends are fixed by fastening screws, and the lower ends are restricted and fixed by the second electrolytic plate 407. This fixing method only requires two fastening screws, which is convenient for assembly and disassembly.

[0063] In other embodiments, the first electrolytic plate 406 and the first diaphragm 408 are simply placed in the first groove 410, and the upper and lower ends of the second housing 402 are provided with first step portions 411. The first electrolytic plate 406 and the first diaphragm 408 are fixed by fixing the two ends of the second electrolytic plate 407 to the two first step portions 411 with fastening screws.

[0064] The first diaphragm 408 can completely separate the first electrolytic plate 406 and the second electrolytic plate 407. Figure 2 The image is not shown; it is only to illustrate the parallel arrangement of the electrolytic plates and the fact that the first groove 410 can accommodate the first electrolytic plate 406 and the first diaphragm 408. That is, the circumferential edge of the first diaphragm 408 abuts or seals against the circumferential inner wall of the second shell 402. The material of the first diaphragm 408 can be asbestos, or a new type of composite diaphragm based on polyphenylene sulfide (PPS) fabric, a tetrafluoroethylene resin modified asbestos diaphragm, a polyether ether ketone fiber diaphragm, a polysulfone fiber diaphragm, etc. The first diaphragm 408 functions to prevent the mixing of hydrogen and oxygen during electrolysis.

[0065] In some embodiments, a stepped receiving groove is provided on the first electrolytic plate 406, and the head of the left end of the fastening screw that fixes the first electrolytic plate 406 is located in the receiving groove, so that the left end of the fastening screw or fastening bolt is flush with the left side of the first electrolytic plate 406, so as not to hinder the fixing of the first diaphragm 408.

[0066] Continue reading Figure 2 ,like Figure 2As shown, a first water inlet 432 is provided in the middle of the first housing 401, and a second water inlet 405 is provided in the middle of the second housing 402. The center lines of the first water inlet 432 and the second water inlet 405 are on the same horizontal plane and are perpendicular to the first electrolytic plate 406 and the second electrolytic plate 407. The first water inlet 432 and the second water inlet 405 are both connected to the first cavity 409. The first groove 410 is located on the right side inside the first cavity 409. Water enters the first cavity 409 from the first water inlet 432, and then generates ozone and hydroxyl radicals through electrolysis by the first electrolytic plate 406 and the second electrolytic plate 407. The electrolyzed water flows out through the second water inlet 405 and enters the washing equipment to achieve the functions of disinfection, sterilization and deodorization.

[0067] Continue reading Figure 2 A first air passage 412 is formed within the inner wall of the second housing 402. A second pipe 404 extends outward from the second water inlet 405. One end of the first air passage 412 is located above the first cavity 409 and communicates with the first cavity 409 on the left side of the first diaphragm 408; the other end of the first air passage 412 is located within the wall of the second pipe 404 and communicates with the outside. Specifically, as... Figure 2 As shown, the starting end of the first air passage 412 is connected to the first cavity 409 and is located above the first cavity 409. Then it extends upward from the starting end and then to the right, and then downward to the position of the second pipe 404. It then extends to the right to the wall of the second pipe 404 until the end of the first air passage 412 is connected to the outside. Based on the above structural configuration, since the first diaphragm 408 can isolate hydrogen and oxygen during the electrolysis process, the gas has difficulty passing through the first diaphragm 408. To avoid the gas accumulating on the left side of the first diaphragm 408, the gas is discharged through the first vent passage 412. After the water flows into the first cavity 409, part of it passes through the first diaphragm 408 and flows out through the second water outlet 405 and the second pipe 404. Another small portion of the water carries away the gas as it flows through the first cavity 409 on the left side of the first diaphragm 408 and flows out through the first vent passage 412. In this invention, the first vent passage 412 is set inside the pipe wall of the second pipe 404. After the second pipe 404 is connected to the pipeline inside the washing equipment, the pipeline inside the washing equipment is fixed by fitting it around the outside of the second pipe 404. Both the second water outlet 405 and the first vent passage 412 can be connected to the pipeline inside the washing equipment to enter the washing drum. This configuration is convenient for connection and does not require multiple connections.

[0068] Continue reading Figure 2In the electrolysis apparatus 4 of the first preferred embodiment, the first housing 401 and the second housing 402 are fastened together by bolts 416. The first housing 401 is provided with a first threaded hole, and the second housing 402 is provided with a second threaded hole. The bolts 416 pass through the first threaded hole and are fastened together with the second threaded hole. A first sealing element 413 is also provided between the first housing 401 and the second housing 402. The first sealing element 413 is a sealing ring, and the sealing ring is located inside the two bolts 416.

[0069] Furthermore, a first pipe 403 extends outward from the first water inlet 432, and the axes of the first pipe 403 and the second pipe 404 coincide.

[0070] See next. Figure 3 The electrolysis device 4 of the second preferred embodiment of the present invention, based on the first preferred embodiment, removes the second tube 404 and further includes a third housing 431. The third housing 431 and the second housing 402 form a second cavity 417. A third water inlet 433 is provided on the third housing 431. The second water inlet 405, the second cavity 417 and the third water inlet 433 are connected in sequence. A third electrolysis plate 418, a second diaphragm 420 and a fourth electrolysis plate 419 are arranged in parallel in the second cavity 417.

[0071] like Figure 3 As shown, the third electrolytic plate 418 and the second diaphragm 420 are placed side by side in the second groove 429 from right to left. When the fourth electrolytic plate 419 is fixed to the second step portion 430, the second diaphragm 420 and the third electrolytic plate 418 are pressed to the right. The third electrolytic plate 418 and the right inner wall of the third housing 431 abut against each other, thereby fixing the third electrolytic plate 418 and the second diaphragm 420.

[0072] The present invention places the third electrolytic plate 418 and the second diaphragm 420 in the second groove 429, and only needs to fix the fourth electrolytic plate 419 on the stepped portion to achieve complete fixation of the third electrolytic plate 418, the fourth electrolytic plate 419 and the second diaphragm 420 without separate fixation, saving installation steps and making disassembly and assembly convenient.

[0073] It should be noted that the present invention does not impose any limitation on the number of the third electrolytic plate 418 and the fourth electrolytic plate 419, such as Figure 3 As shown, there are two third electrolytic plates 418 arranged side by side, and one fourth electrolytic plate 419. However, this is not a limitation, and those skilled in the art can set the specific number of the third electrolytic plates 418 and the fourth electrolytic plates 419 according to the actual situation.

[0074] Furthermore, the third electrolytic plate 418 and the fourth electrolytic plate 419 of the present invention have the same structure, both including a substrate and a boron-doped diamond film disposed on the substrate, that is, a boron-doped diamond film is coated on a conductive substrate. The substrate can be a metallic material or other conductive materials, such as... Figure 3 As shown, a third conductive component 427 and a fourth conductive component 428 are pre-embedded in the third housing 431. During the manufacturing of the third housing 431, the third conductive component 427 and the fourth conductive component 428 are pre-molded in the mold. The third conductive component 427 is connected to the third electrolytic plate 418, and the fourth conductive component 428 is connected to the fourth electrolytic plate 419. The third conductive component 427 is connected to the positive terminal of the power supply, and the fourth conductive component 428 is connected to the negative terminal of the power supply.

[0075] In other embodiments, the third conductive member 427 is connected to the negative terminal of the power supply, and the fourth conductive member 428 is connected to the positive terminal of the power supply.

[0076] In other embodiments, one of the third electrolytic plate 418 and the fourth electrolytic plate 419 comprises a substrate and a boron-doped diamond film disposed on the substrate. The electrolytic plate having the boron-doped diamond film can be connected to the positive terminal of a power supply.

[0077] The third conductive component 427 and the fourth conductive component 428 may be the same or different. They may be conductive sheets, conductive wires, or other conductive structures. Those skilled in the art can set them according to the actual situation.

[0078] Furthermore, the third conductive member 427, which is pre-embedded in the third housing 431, is located in the second groove 429. When the third electrolytic plate 418 is placed in the second groove 429, it can abut against the third conductive member 427. The third conductive member 427 extends into the second groove 429, and its extended portion is embedded in the right inner wall of the third housing 431. This will not hinder the installation of the third electrolytic plate 418, and will also ensure a good connection between the third electrolytic plate 418 and the third conductive member 427. The pre-embedded fourth conductive member 428 is located on the left side of the second groove 429 and abuts against the left side wall of the second step portion 430. Both the third conductive member 427 and the fourth conductive member 428 are partially located inside the third housing 431 and partially located outside the third housing 431.

[0079] Furthermore, Figure 3The upper ends of the two third electrolytic plates 418 are fixed by fastening screws. The fastening screws pass through the two third electrolytic plates 418 and the third conductive member 427 and extend into the inner wall of the third housing 431. This not only improves the stability of the third electrolytic plates 418, but also improves the tightness of the connection between the third electrolytic plates 418 and the third conductive member 427. The fastening screws pass through the fourth electrolytic plate 419 and extend into the second step portion 430, fixing the lower part of the fourth electrolytic plate 419. Since the third electrolytic plates 418 and the second diaphragm 420 are located in the second groove 429, the upper ends are fixed by fastening screws, and the lower ends are restricted and fixed by the fourth electrolytic plate 419. This fixing method only requires two fastening screws, which is convenient for assembly and disassembly.

[0080] In other embodiments, the third electrolytic plate 418 and the second diaphragm 420 are simply placed in the second groove 429, and the upper and lower ends of the third housing 431 are provided with second step portions 430. The third electrolytic plate 418 and the second diaphragm 420 are fixed by fixing the two ends of the fourth electrolytic plate 419 to the two second step portions 430 with fastening screws.

[0081] The second diaphragm 420 can completely isolate the third electrolytic plate 418 and the fourth electrolytic plate 419. Figure 3 The image is not shown, but is only used to illustrate the parallel relationship of the electrolytic plates and the relationship between the second groove 429 and the third electrolytic plate 418 and the second diaphragm 420. That is, the circumferential edge of the second diaphragm 420 abuts or seals against the circumferential inner wall of the third shell 431. The material of the second diaphragm 420 can be asbestos, or a new type of composite diaphragm based on polyphenylene sulfide (PPS) fabric, a tetrafluoroethylene resin modified asbestos diaphragm, a polyether ether ketone fiber diaphragm, a polysulfone fiber diaphragm, etc. The function of the second diaphragm 420 in electrolysis is to prevent the mixing of hydrogen and oxygen.

[0082] In some embodiments, a stepped receiving groove is provided on the third electrolytic plate 418, and the head of the left end of the fastening screw that fixes the third electrolytic plate 418 is located in the receiving groove, so that the left end of the fastening screw or fastening bolt is flush with the left side of the third electrolytic plate 418, so as not to hinder the fixation of the second diaphragm 420.

[0083] Referring again to section 3, the third housing 431 is fastened to the outer wall of the second housing 402, which has the second gate 405, to form the second cavity 417. Specifically, as... Figure 3As shown, the third housing 431 is snapped to the right side of the second housing 402. The second housing 402 is provided with a connecting portion 424, which has a first snap-fit ​​member. The outer wall of the third housing 431 has a second snap-fit ​​member. The second housing 402 and the third housing 431 are connected by the first and second snap-fit ​​members. The first snap-fit ​​member is a protrusion 425, and the second snap-fit ​​member is a slot 426. However, this is not a limitation; the first snap-fit ​​member can be a slot 426, and the second snap-fit ​​member can be a protrusion 425, or other matching snap-fit ​​structures. The connecting portion 424 can be a ring-shaped structure or a columnar structure located above and below the second housing 402. Those skilled in the art can design it according to the actual situation.

[0084] A second sealing element is provided between the second housing 402 and the third housing 431. The second sealing element is a sealing ring, which further improves the sealing performance.

[0085] Further, in the second preferred embodiment, a first air passage 412 is provided on the second housing 402, a second air passage 422 is formed in the inner wall of the third housing 431, a third pipe 421 extends outward from the third water outlet 433, one end of the second air passage 422 is located above the second cavity 417 and is connected to the second cavity 417 on the left side of the second diaphragm 420, and the other end of the second air passage 422 is located in the pipe wall of the third pipe 421 and is connected to the outside. A connecting passage 423 is formed in the inner wall of the third housing 431, and the connecting passage 423 is connected to the second air passage 422, and the connecting passage 423 is connected to the downstream of the starting section of the second air passage 422. When the second housing 402 and the third housing 431 are connected in place, one end of the first air passage 412 is located above the first cavity 409, and the other end of the first air passage 412 is connected to the connecting passage 423. Based on this, the gas in the first cavity 409 on the left side of the first diaphragm 408 is discharged with the water flow through the first gas passage 412, the connecting passage 423, and part of the second gas passage 422, and the gas in the second cavity 417 on the left side of the second diaphragm 420 is discharged with the water flow through all of the second gas passages 422.

[0086] In addition, the first vent passage 412 and the connecting passage 423 are located inside the second sealing element to prevent water and gas leakage. In some other embodiments, a sealing ring is also provided between the first vent passage 412 and the connecting passage 423 to achieve a sealed connection.

[0087] To avoid mixing of the gas generated at the anode and the gas generated at the cathode, both the first electrolytic plate 406 and the fourth electrolytic plate 419 are either anodes or both are cathodes.

[0088] To achieve efficient electrolysis of water flow, multiple hole structures are provided on the first electrolytic plate 406, the second electrolytic plate 407, the third electrolytic plate 418, and the fourth electrolytic plate 419.

[0089] Figure 2 In an embodiment where the electrolysis device having the first gas passage 412 is connected to the treatment agent device 5, and employs... Figure 6 In the connection method, the second fixing part 512 is a ring structure, and the insertion pipe 511 is located inside the ring-shaped second fixing part 512. A water inlet (not shown in the figure) is provided on the area of ​​the first box 51 between the outer peripheral side of the insertion pipe 511 and the inner peripheral side of the second fixing part 512. The first fixing part 434 is also a ring structure. After the insertion pipe 511 is inserted into the second pipe 404, the first fixing part 434 and the second fixing part 512 are sealed together. Therefore, the outer peripheral side of the insertion pipe 511 and the inner peripheral side of the second fixing part 512 form a ring-shaped sealed cavity. The first air passage 412 located in the pipe wall of the second pipe 404 is in the sealed cavity and is connected to the water inlet so that the water in the first air passage 412 enters the first box through the water inlet.

[0090] Figure 3 When the embodiment of the electrolysis device having a first gas passage 412 and a second gas passage 422 is connected to the treatment agent device 5, and adopts... Figure 6 In the connection method described above, after the insertion tube 511 is inserted into the third tube 421, the first fixing part 434 and the second fixing part 512 are sealed together. Therefore, the outer periphery of the insertion tube 511 and the inner periphery of the second fixing part 512 form an annular sealed cavity. The second air passage 422 located inside the wall of the third tube 421 is in the sealed cavity and is connected to the water inlet so that the water in the second air passage 422 enters the first box through the water inlet.

[0091] To achieve a sealed connection between the annular first fixing part 434 and the annular second fixing part 512, a sealing ring can be provided between them, and the sealing ring is located inside the plurality of circumferential fasteners.
