[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0023] Refer to the attached drawings of the specificationFigure 1 To the attached Figure 3 , a waterway structure integration system for an RO and ultrafiltration machine, comprising a waterway board 3 and a filter element module. The waterway board includes a water inlet 10 and a water outlet 14; the filter element module is connected to the waterway board 3, and the filter element module includes a first-stage filter element 11, a second-stage filter element 12, and a third-stage filter element 13. The second-stage filter element can be an RO filter element, and the concentrated water generated by it can flow out from the concentrated water outlet 12b through a waste water solenoid valve or a waste water plug 12a. In addition, the waterway board is provided with at least two reserved ports; wherein, when the system is used as an ultrafiltration machine, water flows in sequence from the water inlet 10 into the filter element module for filtration, and finally flows out from the water outlet 14 for use by the user; when the system is used as an RO machine, a first integration module 21 and a second integration module 22 are connected to the reserved ports on the waterway board 3 (i.e., these modules can be installed or disassembled on the waterway board). For example, referring to Figure 3 , a first integration module 21 is arranged between the water inlet 10 and the first-stage filter element 11, a second integration module 22 is arranged between the second-stage filter element 12 and the third-stage filter element 13, and a water pump 23 is also arranged between the first-stage filter element 11 and the second-stage filter element 12. The water pump 23 is connected and arranged on the waterway board 3, and the water pump can also be arranged in a detachable manner on the waterway board. Among them, the first integration module 21 highly integrates the pressure switches and solenoid valves that are scattered in various waterway channels in the prior art into a modular design (i.e., a solenoid valve structure integrating pressure switches), and integrates them on the first integration module 21; the second integration module 22 highly integrates the pressure switches, check valves, flow meters, TDS detectors, etc. that are scattered in various waterway channels in the prior art into a modular design (i.e., a highly integrated component waterway module), and integrates them on the second integration module 22. In this way, this integrated module design can effectively shorten the working hours, reduce labor, and lower costs, having high economic benefits, and at the same time reducing customer complaints and complaints. When the system is used as an RO machine, the first integration module 21, the second integration module 22, the filter element module, and the water pump 23 can be compactly arranged on the waterway board 3; when the system is used as an ultrafiltration machine, the first and second integration modules and the water pump are removed, and it can be used as an ultrafiltration machine. In this way, the setting method of this system enables the RO machine and the ultrafiltration machine to share the waterway board, thereby flexibly converting between the RO machine and the ultrafiltration machine. Of course, according to different customer requirements, the appearance and type of the product can also be flexibly changed, enhancing the commonality and greatly reducing the product development cost.

[0024] The following will be combined with the attached Figure 4 To the attached Figure 6A detailed description is given to the first integrated module (i.e., the solenoid valve structure integrating a pressure switch). The solenoid valve integrating the pressure switch includes a first water inlet passage 41, a housing 40, and a first water outlet passage 42. The housing 40 includes an intermediate region 40a, and a solenoid valve region 40b and a pressure switch region 40c respectively disposed on both sides of the intermediate region 40a. The intermediate region 40a includes a first cavity 43a and a second cavity 43b. The second cavity 43b can be blocked or communicated with the first cavity 43a when the solenoid valve is powered off or on. A first diaphragm 44 is disposed between the intermediate region 40a and the pressure switch region 40c. A third cavity 43c is formed between the first diaphragm 44 and the intermediate region 40a, and the third cavity 43c is communicated with the first cavity 43a. A push rod 45, a first spring member 46, and a micro switch 47 are further disposed in the pressure switch region 40c. The push rod 45 and the third cavity 43c are respectively disposed on both sides of the first diaphragm 44, and the first spring member 46 is located between the push rod 45 and the micro switch 47. The micro switch 47 may further include a connection wire 47a extending out of the pressure switch region 40c. The solenoid valve region 40b is disposed on the other side of the intermediate region 40a relative to the pressure switch region 40c. A second diaphragm 48 is disposed between the solenoid valve region 40b and the intermediate region 40a. A magnet 49, a second spring member 50, and a solenoid valve magnet 51 are further disposed in the solenoid valve region 40b. Among them, the magnet 49 is disposed between the second diaphragm 48 and the second spring member 50, and the solenoid valve magnet 51 is disposed around the outer periphery of the second spring member 50 and the magnet 49.

[0025] In this way, if the microswitch 47 is of the normally open type, during operation, water flows from the first water inlet passage 41 into the first cavity 43a and the third cavity 43c. The first diaphragm 44 is pushed up under the action of water pressure, causing deformation of the diaphragm, so that the push rod 45 can overcome the resistance of the first spring member 46 and the microswitch 47 and move. When the water pressure reaches the set value for the pressure switch to close, the microswitch 47 closes, the circuit is conducted, and the solenoid valve is energized. At this time, the solenoid valve magnet 51 in the solenoid valve area 40b generates a magnetic force to attract the magnet 49. The magnet 49 compresses the second spring member 50 and loses the pressure on the second diaphragm 48. At this time, water flows from the first cavity 43a into the second cavity 43b and finally discharges from the first water outlet passage 42. Similarly, if the microswitch 47 is of the normally closed type, water flows from the first water inlet passage 41 into the first cavity 43a, the second cavity 43b and the third cavity 43c and flows from the second cavity 43b to the first water outlet passage 42. When the water pressure in the third cavity 43c reaches a certain value, the first diaphragm 44 is pushed up under the action of this water pressure, causing deformation of the diaphragm, so that the push rod 45 can overcome the resistance of the first spring member 46 and the microswitch 47. When the water pressure continues to increase to the set value for the pressure switch to open, the microswitch 47 opens, the circuit is disconnected, and the solenoid valve is in a de-energized state. At this time, the solenoid valve magnet 51 in the solenoid valve area 40b loses the magnetic attraction to the magnet 49. The magnet 49 is pushed open by the second spring member 50 and abuts against the second diaphragm 48, exerting pressure on this diaphragm. At this time, water cannot flow from the first cavity 43a into the second cavity 43b, blocking the water flow, and the first water outlet passage 42 stops discharging water. It is easy to know that this pressure switch can be either a high-pressure switch or a low-pressure switch. In this way, this solenoid valve structure integrating the pressure switch highly integrates and modularizes the pressure switch and the solenoid valve. The assembly is simple, simplifies the reserved openings required for the water circuit board mold opening, can effectively reduce the assembly labor, working hours and costs of the whole unit, has high economic benefits, and meets the needs of customers.

[0026] The following will be combined with the attached Figure 7 to the attached Figure 9A detailed description is given to the second integrated module (i.e., the highly integrated component waterway module). The highly integrated component waterway module includes a second water inlet channel 61, a housing 62, and a second water outlet channel 63. The second water inlet channel 61 and the second water outlet channel 63 can be conventional quick-connect interfaces. A check valve 621 and a flow meter 622 are arranged inside the housing 62. The check valve 621 is arranged adjacent to the second water inlet channel 61 to ensure the unidirectionality of the fluid and prevent the medium from flowing backward, which may affect the water quality. The flow meter 622 includes a flow meter impeller b and is connected to a flow meter circuit board 5 on the housing 62. A first bypass pipe 64a and a second bypass pipe 64b are arranged on the housing 62 (between the second water inlet channel 61 and the second water outlet channel 63). The flow meter 622 is located between the check valve 621 and the second bypass pipe 64b. A chamber c is included in the first bypass pipe 64a, and the chamber c is communicated with the channel inside the housing 62. The first bypass pipe 64a is connected with a pressure switch 66. The pressure switch 66 can conduct or disconnect the circuit connection under the action of water pressure. Optionally, the pressure switch 66 and the first bypass pipe 64a can be connected and fixed by a fixing screw d. The pressure switch 66 can be either a high-pressure switch or a low-pressure switch. The pressure switch 66 includes a body 60, a push block 68, a micro switch 69, and a pressure-regulating elastic member 70. A diaphragm 67 is arranged between the pressure switch 66 and the chamber c of the first bypass pipe 64a. A push block 68 is arranged on the diaphragm 67. A micro switch 69 and a pressure-regulating elastic member 70 are arranged at the upper end of the push block 68. Preferably, the push block 68 includes a main body 681 and an extension 682. The micro switch 69 is arranged at the upper part of the main body 681, and the pressure-regulating elastic member 70 is arranged at the upper end of the extension 682, so as to better ensure the reliability of the work. The push blocks 68, the micro switch 69, and the pressure-regulating elastic member 70 are all arranged inside the body 60 of the pressure switch 66. At the same time, the second bypass pipe 64b is connected with a TDS probe 65. The TDS probe 65 extends into the second bypass pipe 64b. Optionally, the TDS probe 65 and the second bypass pipe 64b can be connected by threads. At the same time, in order to ensure the sealing performance between the two, a sealing ring a can be arranged at the connection position of the two, so as to fix and seal the two.

[0027] When water flows into the housing 62 from the second water inlet passage 61, the water impacts the flowmeter impeller b after passing through the check valve 621, driving the flowmeter 622 to work. Then the water continues to pass through the TDS probe 65, and the TDS probe 65 is used to detect the water quality condition, and then flows out from the second water outlet passage 63. At the same time, while the water impacts the flowmeter impeller b, the water enters the chamber c from the housing 62. At this time, the diaphragm 67 deforms under the action of water pressure. The diaphragm 67 pushes up the push block 68 to move upward, thereby overcoming the resistance of the microswitch 69 and the pressure regulating elastic member 70, and then pushing open the button of the microswitch 69, thereby closing or disconnecting the circuit (the original state of the microswitch can be normally closed or normally open). In this way, this highly integrated component waterway module highly integrates and modularizes the pressure switch, check valve, flowmeter and TDS detector. The assembly is simple, simplifies the reserved openings required for the waterway board mold opening, can effectively reduce the assembly labor, working hours and cost of the whole unit, has high economic benefits, and meets the needs of customers.
