[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention.

[0026] Reference Manual Attached Figure 1 To Attachment Figure 3, an integrated system of RO and ultrafiltration waterway structure, comprising a waterway plate 3 and a filter element module, the waterway plate comprising a water inlet 10 and a water outlet 14; the filter element module is connected to the waterway plate 3, the filter element module comprises 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 produced by it can flow out from the concentrated water outlet 12b through a wastewater solenoid valve or a wastewater plug 12a, in addition, the waterway plate is also provided with at least two reserved ports; wherein, when the system is used as an ultrafiltration machine, water flows from the water inlet 10 into the filter element module in sequence for filtration, and finally flows out from the water outlet 14 for use by users; when the system is used as an RO machine, a first integrated module 21 and a second integrated module 22 are connected to the reserved port of the waterway plate 3 (that is, these modules can be installed or removed on the waterway plate), for example, with reference to Figure 3 A first integrated module 21 is arranged between the water inlet 10 and the first filter element 11, a second integrated module 22 is arranged between the second filter element 12 and the third filter element 13, and a water pump 23 is also arranged between the first filter element 11 and the second filter element 12. The water pump 23 is connected and arranged on the waterway board 3, wherein the water pump can also be arranged to be detachably installed on the waterway board. Among them, the first integrated module 21 highly integrates the existing pressure switch and solenoid valve dispersed in various waterway channels into a modular design (i.e., a solenoid valve structure integrating pressure switch into one), and integrates them on the first integrated module 21; the second integrated module 22 highly integrates the existing pressure switch, one-way valve, flow meter, TDS detector, etc. dispersed in various waterway channels into a modular design (i.e., a highly integrated component waterway module), and integrates them on the second integrated module 22. In this way, the integrated module design can effectively shorten the working hours, reduce labor, reduce costs, have high economic benefits, and also reduce customer complaints. When the system is used as an RO machine, the first integrated module 21, the second integrated module 22, the filter element module and the water pump 23 can be compactly arranged on the waterway plate 3; when the system is used as an ultrafiltration machine, the first and second integrated modules and the water pump can be removed to use it as an ultrafiltration machine. In this way, the arrangement of this system enables the RO machine and the ultrafiltration machine to share the waterway plate, thereby flexibly converting the RO machine and the ultrafiltration machine. Of course, the appearance and type of the product can also be flexibly changed according to the different needs of customers, the commonality is enhanced, and the development cost of the product is greatly reduced.

[0027] The following will be combined with the attached Figure 4 To Attachment Figure 6The first integrated module (i.e., the electromagnetic valve structure with integrated pressure switch) is described in detail. The electromagnetic valve with integrated pressure switch includes a first water inlet channel 41, a housing 40, and a first water outlet channel 42. The housing 40 includes a middle area 40a, and a solenoid valve area 40b and a pressure switch area 40c respectively disposed on both sides of the middle area 40a. The middle area 40a includes a first cavity 43a and a second cavity 43b. The second cavity 43b can be blocked or connected with the first cavity 43a when the electromagnetic valve is powered off or powered on. A pressure switch is provided between the middle area 40a and the pressure switch area 40c. There is a first diaphragm 44, and a third cavity 43c is formed between the first diaphragm 44 and the middle area 40a, and the third cavity 43c is connected to the first cavity 43a; a push rod 45, a first spring member 46 and a micro switch 47 are also provided in the pressure switch area 40c, and the push rod 45 and the third cavity 43c are respectively placed 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, and the micro switch 47 may also include a connecting line 47a passing through the pressure switch area 40c. The solenoid valve area 40b is placed on the other side of the middle area 40a relative to the pressure switch area 40c, and a second diaphragm 48 is arranged between the solenoid valve area 40b and the middle area 40a. A magnet 49, a second spring member 50 and a solenoid valve magnet 51 are also arranged in the solenoid valve area 40b, wherein the magnet 49 is arranged between the second diaphragm 48 and the second spring member 50, and the solenoid valve magnet 51 is arranged around the second spring member 50 and the outer periphery of the magnet 49.

[0028] In this way, if the microswitch 47 is of the normally open type, when working, water flows from the first water inlet channel 41 into the first cavity 43a and the third cavity 43c, and the first diaphragm 44 is lifted up under the action of the water pressure, causing the deformation of the diaphragm, so that the push rod 45 can overcome the resistance of the first spring member 46 and the microswitch 47 to move it. When the water pressure reaches the set value for closing the pressure switch, the microswitch 47 is closed, the circuit is turned on, and the solenoid valve is energized; at this time, the solenoid valve magnet 51 in the solenoid valve area 40b generates magnetic force, attracting the magnet 49, and 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 is finally discharged from the first water outlet channel 42. Similarly, if the micro switch 47 is of the normally closed type, water flows from the first water inlet channel 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 channel 42; when the water pressure in the third cavity 43c reaches a certain value, the first diaphragm 44 is lifted up by the water pressure, causing the diaphragm to deform, so that the push rod 45 can overcome the resistance of the first spring member 46 and the micro switch 47. When the water pressure continues to increase and reaches the set value of the pressure switch disconnection, the micro switch 47 is disconnected, the circuit is disconnected, and the solenoid valve is in a power-off state; at this time, the solenoid valve magnet 51 in the solenoid valve area 40b loses its magnetic attraction to the magnet 49, and the magnet 49 is pushed open by the second spring member 50, resting on the second diaphragm 48, exerting pressure on the diaphragm. At this time, the water flow cannot enter the second cavity 43b from the first cavity 43a, blocking the water flow, and the first water outlet channel 42 stops discharging water. It is easy to know that the pressure switch can be a high-pressure switch or a low-pressure switch. In this way, the solenoid valve structure with integrated pressure switch has a highly integrated modular design of the pressure switch and the solenoid valve, which is easy to assemble and simplifies the reserved openings required for the mold opening of the waterway plate. It can effectively reduce the labor, working hours and cost of the whole machine assembly, has high economic benefits, and meets the needs of customers.

[0029] The following will be combined with the attached Figure 7 To Attachment Fig. 9The second integrated module (i.e., the highly integrated component water channel module) is described in detail. The highly integrated component water channel module includes a second water inlet channel 61, a shell 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 one-way valve 621 and a flow meter 622 are arranged in the shell 62. The one-way 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 back and affecting the water quality; the flow meter 622 includes a flow meter impeller b and is connected to the flow meter circuit board 5 on the shell 62; the shell 62 (between the second water inlet channel 61 and the second water outlet channel 63) is connected to the flow meter circuit board 5 on the shell 62; A first bypass pipe 64a and a second bypass pipe 64b are provided in the housing 62, and the flow meter 622 is located between the one-way valve 621 and the second bypass pipe 64b. The first bypass pipe 64a includes a chamber c, which is connected to the channel in the housing 62. The first bypass pipe 64a is connected to a pressure switch 66, which can open or close 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, and the pressure switch 66 can be 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 provided between the pressure switch 66 and the chamber c of the first bypass pipe 64a. A push block 68 is provided on the diaphragm 67. The micro switch 69 and the pressure regulating elastic member 70 are provided on the upper end of the push block 68. Preferably, the push block 68 includes a body 681 and an extension 682. The micro switch 69 is provided on the upper part of the body 681. The pressure regulating elastic member 70 is provided on the upper end of the extension 682. And better ensure the reliability of work; the push blocks 68, micro switch 69 and pressure regulating elastic member 70 are all arranged in the body 60 of the pressure switch 66; at the same time, the second bypass pipe 64b is connected to the TDS probe 65, and 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 of the two, a sealing ring a can be provided at the connection position of the two, so that the two are fixedly sealed.

[0030] When water flows into the shell 62 from the second water inlet channel 61, the water flows through the one-way valve 621 and then impacts the flow meter impeller b, driving the flow meter 622 to work, and then the water flows continue to pass through the TDS probe 65, and the water quality is detected by the TDS probe 65, and then flows out from the second water outlet channel 63; at the same time, the water flows into the chamber c from the shell 62 while impacting the flow meter impeller b. At this time, the diaphragm 67 is deformed under the action of water pressure, and the diaphragm 67 pushes the push block 68 to move upward, thereby overcoming the resistance of the microswitch 69 and the pressure regulating elastic member 70, and then pushes open the button of the microswitch 69, thereby closing or disconnecting the circuit (the original state of the microswitch can be either normally closed or normally open). In this way, the highly integrated component water module has a highly integrated modular design of pressure switches, one-way valves, flow meters and TDS detectors. It is easy to assemble and simplifies the reserved openings required for water board mold opening. It can effectively reduce the labor, working hours and costs of whole machine assembly, has high economic benefits and meets customer needs.
