DETAILED DESCRIPTION

[0034] To make the purposes, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. The described embodiments are some but not all of the embodiments of the present application. The detailed description of the embodiments of the present application provided below in the drawings is not intended to limit the scope of the present application, but merely represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of the present application.

[0035] As shown in Figures 1-7 The waterway system of the present embodiment includes a waterway plate 1, a filter element seat 2, a composite filter element 3, and a reverse osmosis filter element 4. The waterway plate 1 includes a waterway plate body 11 and a bridging pipe 12. The waterway plate body 11 is integrally formed from stainless steel and can be formed by casting or machining from a stainless steel sheet. The waterway plate body 11 includes a first waterway plate body 111 and a second waterway plate body 112 connected together, i.e., the first waterway plate body 111 and the second waterway plate body 112 are in a non-separated state and do not need to be connected by additional assembly processes such as plugging together of two waterway plate modules, thereby reducing assembly difficulty. The first waterway plate body 111 is provided with a first waterway and the second waterway plate body 112 is provided with a second waterway. The first waterway and the second waterway are connected by the bridging pipe 12, thereby avoiding the need to open a complex flow channel in the waterway plate and directly enabling the flow channel to span by the bridging pipe 12. There is no internal flow channel intersection or multiple branch waterways. The waterway layout is reasonable and the volume of the waterway plate is smaller. In the machining process of the waterway plate of the present embodiment, the stainless steel sheet is first divided into the first waterway plate body 111 and the second waterway plate body 112, and then each region is independently machined to form the corresponding waterway, thereby forming the two waterway plate body modules connected together.

[0036] The filter element seat 2 includes a first filter element seat 21 and a second filter element seat 22. The first filter element seat 21 is mounted on the first waterway plate body 111 and the second filter element seat 22 is mounted on the second waterway plate body 112. The composite filter element 3 is mounted on the first filter element seat 21 and the reverse osmosis filter element 4 is mounted on the second filter element seat 22. The first filter element seat 21 and the second filter element seat 22 are each provided with a through hole in communication with the corresponding waterway plate body. A valve body is mounted in the through hole. The valve body includes a valve core and a spring. The valve body is a prior art and its specific structure is not described in detail. When the composite filter element 3 and the reverse osmosis filter element 4 are mounted on the corresponding filter element seats, the valve core is pressed downward to move, so that the through hole is in an open state. The composite filter element 3 is in communication with the first waterway and the reverse osmosis filter element 4 is in communication with the second waterway. In this way, a complete waterway system is formed, thereby avoiding the need to provide two or more filter elements to achieve multi-stage filtration in the water purifying device of the prior art, thereby reducing the volume of the entire water purifying device.

[0037] As Figures 3-6 The first waterway plate body 111 is provided with a raw water inlet 1114, a clean water outlet 1115, a pure water outlet 1116, a pure water inlet 1118, a pure water outlet 1119 and a second waste water outlet 1117, and the raw water inlet 1114, the clean water outlet 1115, the pure water outlet 1116 and the second waste water outlet 1117 are all connected with the waterway connecting pipe 15. The raw water inlet 1114, the clean water outlet 1115, the pure water outlet 1116 and the second waste water outlet 1117 are all located on the same end face of the first waterway plate body 111, which is the end of the first waterway plate body 111 not connected with the second waterway plate body 112. This design facilitates the installation of the waterway connecting pipe 15 and makes the entire pipeline arrangement more orderly and easier to assemble. The first waterway includes a raw water flow channel 1111 and a clean water flow channel 1112. The raw water flow channel 1111 is connected with the raw water inlet 1114, and the tap water is guided into the waterway plate through the raw water inlet 1114. The clean water flow channel 1112 is connected with the clean water outlet 1115, and the clean water filtered by the composite filter element 3 is guided out.

[0038] The second waterway plate body 112 is provided with a water inlet 1121, a water outlet 1122 and an RO waste water outlet (indicated in the figure). The through hole on the second filter element seat 22 is in communication with the water inlet 1121, the water outlet 1122 and the RO waste water outlet, so that the reverse osmosis filter element 4 is in communication with the second waterway. The second waterway includes a water inlet flow channel 1123 and a waste water flow channel 1124. The reverse osmosis filter element 4 is in communication with the water inlet flow channel 1123 through the water inlet 1121, and the water flowing through the second waterway is guided into the reverse osmosis filter element 4. The water outlet 1122 guides the pure water filtered by the reverse osmosis filter element 4 out. The RO waste water outlet is in communication with the waste water flow channel 1124, and the waste water generated by the reverse osmosis filter element 4 is discharged.

[0039] The composite filter element 3 is a PCT composite filter element, which has a first filter element and a second filter element inside. The first filter element layer is composed of a first PP cotton layer, a carbon fiber layer and a second PP cotton layer. The second filter element is an activated carbon rod. The composite filter element 3 is provided with a PP water inlet 31, a PP water outlet 32, a C2 water inlet 33 and a C2 water outlet 34. The PP water inlet 31 and the PP water outlet 32 are in communication with the first filter element layer, and the C2 water inlet 33 and the C2 water outlet 34 are in communication with the second filter element. The PP water inlet 31 is in communication with the raw water flow channel 1111, and the tap water is guided into the first filter element layer of the composite filter element 3. After being filtered by the first filter element layer, the filtered clean water is guided out of the PP water outlet 32. The PP water outlet 32 is in communication with the clean water flow channel 1112, and the clean water outlet 1115 is connected with one end of the clean water flow channel 1112. The clean water is guided out of the clean water outlet 1115 and then guided to the water use port through the waterway connecting pipe 15.

[0040] The bridge pipe 12 comprises a first bridge pipe 121 and a second bridge pipe 122. One end of the first bridge pipe 121 is connected with the purified water flow channel 1112, so that the purified water is guided into the first bridge pipe 121. The other end of the first bridge pipe 121 is communicated with the water inlet flow channel 1123, so that the purified water filtered by the composite filter element 3 is guided into the reverse osmosis filter element 4 for secondary filtration. One end of the second bridge pipe 122 is inserted into the water outlet 1122, and the other end is inserted into the pure water inlet 1118 on the first waterway plate body 11, so that the purified water filtered by the reverse osmosis filter element 4 is guided into the first waterway plate body 11. The C2 water inlet 33 is communicated with the pure water inlet 1118, so that the purified water filtered by the reverse osmosis filter element 4 enters the second filter element in the composite filter element 3, and the pure water filtered by the activated carbon rod improves the taste of the pure water. The C2 water outlet 34 is communicated with the pure water outlet 1119, so that the purified water filtered by the activated carbon rod is guided out of the C2 water outlet 34, and finally guided out of the pure water outlet 1119 and then guided to the water using end through the pure water outlet 1116. In the waterway system in the embodiment, the composite filter element is used to integrate multiple stages of filtration, and the second bridge pipe 122 is used to communicate the waterway between the composite filter element and the reverse osmosis filter element, so that an additional flow channel is avoided in the waterway plate, and the waterway is simplified. The first bridge pipe 121, the second bridge pipe 122, the filter element seat 2 and the waterway connecting pipe 15 are all made of stainless steel, so that the pipes through which the water flows are all made of stainless steel. The stainless steel has good antibacterial performance, so that bacteria are not likely to breed in the pipes, and the pipes are not likely to deform.

[0041] As shown in Figures 3-4 , the side surface of the first waterway plate body 111 is inwardly recessed at the connection with the second waterway plate body 112 to form a mounting area 1113. The second bridge pipe 122 is provided with a TDS sensor for detecting the TDS value of the pure water, monitoring the water quality, and facilitating the user to know whether the reverse osmosis filter element 4 needs to be replaced in time. The TDS sensor is located at the mounting area 123, so that the TDS sensor is not excessively protruded relative to the outermost side of the waterway plate 1, and the space of the waterway plate 1 is fully utilized, thereby reducing the space occupied by the TDS sensor on the waterway plate 1. In the actual processing process, the first waterway plate body 111 is inwardly cut to form the mounting area 1113, because there are fewer flow channels at the connection of the first waterway plate body 111 and the second waterway plate body 112. Specifically, the composite filter element 3 and the reverse osmosis filter element 4 are located at the two ends of the waterway plate body 11, and correspondingly, the first waterway and the second waterway are also concentrated at the two ends of the waterway plate body 11, so that there are fewer flow channels in the middle region of the waterway plate body 11. The middle region is the connection of the first waterway plate body 111 and the second waterway plate body 112, so that the connection can be inwardly recessed, thereby reasonably utilizing the space of the waterway plate.

[0042] As shown in Figure 4 , Figure 7 , Figure 8As shown, the waterway plate body 11 is fixedly installed with a clamp 13, and the two ends of the second bridge pipe 122 are arranged in the clamp 13, so that the second bridge pipe 122 is fixed on the waterway plate body 11. The side wall of the second bridge pipe 122 is provided with a water inlet hole 1221 and a water outlet hole 1222, the water inlet hole 1221 is communicated with the water outlet 1122, and the water outlet hole 1222 is communicated with the first waterway. In this embodiment, the side wall of the second bridge pipe 122 has an inwardly recessed plane, and the water inlet hole 1221 and the water outlet hole 1222 are both arranged at the plane. In this way, when the second bridge pipe 122 is installed, the second bridge pipe 122 is directly attached to the waterway plate body 11, greatly reducing the volume of the entire waterway plate, and better fixing the second connecting pipe 122 on the waterway plate body 11.

[0043] Specifically, the second bridge pipe 122 includes a connecting pipe 1223 having an inner cavity and a sleeve pipe 1224, the connecting pipe 1223 is inserted into the sleeve pipe 1224 and is sealingly connected, and a limiting ring 1225 is arranged at the connecting position of the connecting pipe 1223 and the sleeve pipe 1224. In actual use, the second bridge pipe 122 is machined by a machine tool, which can effectively avoid the problem of sand holes caused by casting. The second bridge pipe 122 is arranged in two parts, which facilitates machine tool machining. In addition, the connecting end 1226 of the connecting pipe is provided with an annular groove, and a sealing ring can be arranged in the annular groove, so that the connecting pipe 1223 is inserted into the sleeve pipe 1224 to realize sealing, and then the limiting ring 1225 is clamped tightly, which can effectively avoid water leakage at the connecting position.

[0044] As shown in the figure, Figures 3-5 The waterway plate body 11 is also provided with a booster pump and an electromagnetic valve 18 (not shown in the figure), and the waterway plate body 11 is provided with a booster pump water inlet 1126 and a booster pump water outlet 1125 for installing the booster pump, the booster pump water inlet 1126 is communicated with the water inlet flow channel 1123, so that the booster pump is connected to the clean water in the water inlet flow channel 1123; the booster pump water outlet 1125 is communicated with the water inlet 1121, so that the booster pump is inserted into the water inlet 1121, thereby connecting the water inlet flow channel 1123 and the water inlet 1121, improving the flow rate of clean water, and avoiding that the flow rate of pure water filtered by the reverse osmosis filter element 4 is too small. Specifically, the booster pump water inlet 1126 is arranged on the side of the second waterway plate body 112, and the electromagnetic valve 18 is also arranged on the side of the first waterway plate body 11, the water inlet end of the electromagnetic valve 18 is communicated with the clean water flow channel 1112, and the water outlet end of the electromagnetic valve 18 is communicated with the first bridge pipe 121, so that the flow direction of clean water is controlled by the electromagnetic valve 18, avoiding that clean water spills when the reverse osmosis filter element 4 is replaced.

[0045] In order to avoid the influence of water pressure changes in different time periods on the outlet end of the waterway system, the waterway plate body 11 is also provided with a high-pressure switch 16 connected in series at the pure water outlet 1116. The high-pressure switch 16 is used to monitor the water pressure of the waterway system to ensure stable water flow. At the same time, it can also facilitate the control and adjustment of the booster pump pressure, avoiding the unstable water flow caused by excessively high or low pressure of the booster pump.

[0046] Further, the waterway plate 1 is provided with a third bridge pipe 123, the second waterway plate body 112 is provided with a check valve 1127 and a first wastewater outlet 1128, one end of the check valve 1127 is communicated with the wastewater channel 1124, and the other end is inserted into the first wastewater outlet 1128 to guide the wastewater generated by the reverse osmosis filter element 4 to the first wastewater outlet 1128. The two ends of the third bridge pipe 123 are connected with the first wastewater outlet 1128 and the second wastewater outlet 1117 respectively, so as to guide the wastewater to the second wastewater outlet 1117 through the third bridge pipe 123, and then discharge it to the outside from the waterway connecting pipe 15 at the third wastewater outlet 1117, avoiding backflow of the wastewater.

[0047] In the waterway system of the embodiment, tap water is connected to the first waterway plate body 111 from the raw water inlet 1114, and then guided to the composite filter element 3 through the PP water inlet. After filtration, the purified water is guided out from the PP water outlet 32, a part of which is guided out from the purified water outlet 1115 for use by the user in non-direct drinking scenarios such as washing vegetables; the other part of the purified water is guided to the second waterway plate body 112 through the first bridge pipe 121, and then guided to the reverse osmosis filter element 4 through the water inlet 1121. The purified water filtered by the reverse osmosis filter element 4 is guided out from the water outlet 1122, and then guided to the purified water inlet 1118 on the second waterway plate body 111 through the second bridge pipe 121. After being improved in taste by the composite filter element 3 again, the purified water is guided out from the purified water outlet 1119, and finally guided to the water end for direct drinking by the user through the purified water outlet 1116. The wastewater generated after filtration by the reverse osmosis filter element 4 is unidirectionally guided to the first wastewater outlet 1128 through the check valve 1127, and then guided to the second wastewater outlet 1117 through the third connecting pipe 124 for discharge.

[0048] The embodiment also provides a water purification equipment, and a waterway system of the water purification equipment is as shown in the figure. Figures 1-2 The water purification equipment includes the waterway system and a support 5. The support 5 is provided with a mounting seat 51 and a connecting column 52.
