[0002] Drinking water safety has become a growing concern in recent years. Tap water contains various bacteria and impurities, necessitating filtration before drinking. Existing dual-discharge microfiltration and reverse osmosis water purifiers primarily utilize PE pipes and quick-connect connectors for waterway connections. However, these systems suffer from complex assembly, low efficiency, high labor costs, and a clunky overall structure.

[0003] Due to the unreasonable structural design of the water channel plate, bubbles will accumulate around the TDS sensor, resulting in inaccurate values and large errors in TDS detection, making it impossible to accurately know the user's local water quality. Utility Model Content

[0004] The main purpose of the utility model is to provide a water channel integrated device to solve the problem of inaccurate TDS detection values caused by unreasonable water channel plate structure design of existing microfiltration water and reverse osmosis dual-outlet water purifiers.

[0005] According to an embodiment of the present invention, a waterway integration device is proposed, which includes: a waterway plate housing, wherein an inlet waterway, a water pump waterway, a wastewater waterway, a clean water waterway and a microfiltration waterway are arranged in the waterway plate housing; a pre-filter element, a terminal inlet filter element and a post-filter element are arranged outside the waterway plate housing; wherein, the inlet waterway is connected to the water inlet of the pre-filter element, and the pre-filter element includes two water outlets, one of which is connected to the terminal inlet filter element through the water pump waterway, and the other is connected to the water outlet. The outlet is connected to the microfiltration water channel; the terminal water inlet filter element includes two water outlets, one of which is connected to the water inlet of the post-filter element, and the other is connected to the wastewater water channel; the water outlet of the post-filter element is connected to the clean water water channel; wherein, a TDS sensor is also provided in the clean water water channel, and the waterway plate shell opposite to the TDS sensor protrudes upward to form a ramp structure, so that the height of the waterway flow channel near the TDS sensor is smaller than the height of other waterway flow channels.

[0006] Wherein, the TDS sensor includes a TDS probe, and the TDS probe is located in the middle of the ramp structure.

[0007] The TDS sensor includes a TDS probe, and the TDS probe is perpendicular to the water flow direction.

[0008] Wherein, the slope angle of the ramp structure is between 10-80 degrees.

[0009] Wherein, the slope angle of the ramp structure is between 30-60 degrees.

[0010] Wherein, the water outlet flow rate of the microfiltration water channel is greater than the water outlet flow rate of the water purification water channel.

[0011] Wherein, the pre-filter element, the terminal water inlet filter element and the post-filter element are arranged on the lower surface of the waterway plate housing.

[0012] Wherein, the pre-filter element is an activated carbon filter element or a PP cotton filter element.

[0013] Wherein, the terminal water inlet filter element is a reverse osmosis filter element, a nanofiltration filter element or an ultrafiltration filter element.

[0014] Wherein, the post-filter element is a granular activated carbon filter element or a compressed activated carbon filter element.

[0015] According to the technical solution of the present invention, a waterway ramp design is added to the waterway plate of a microfiltration water and reverse osmosis dual-outlet water purifier, so that the metal probe of the TDS sensor is located in the middle position of the waterway ramp structure, thereby increasing the flow rate of the water flow, and bubbles in the waterway plate are not easily gathered under the TDS probe, thereby effectively improving the detection accuracy of the TDS sensor.

[0022] To make the purpose, technical solutions, and advantages of the present invention more clear, the following will provide a clear and complete description of the technical solutions of the present invention in conjunction with specific embodiments of the present invention and the corresponding drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.

[0023] Although the present invention may include various embodiments in different forms, for some preferred embodiments described in detail in the specification and shown in the drawings, it should be understood that the contents disclosed in the present invention should be regarded as schematic illustrations of the principles of the present invention, and these shown embodiments are not intended to limit the scope of protection of the present invention.

[0024] The technical solutions provided by various embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0025] According to an embodiment of the present invention, a water channel integrated device is provided, which can be applied to a water purifier with dual water outlet functions of microfiltration (MF) and reverse osmosis (RO).

[0026] refer to Figure 1 and Figure 2 The integrated waterway system comprises a waterway housing 1, which includes a base plate and a cover. Within the housing 1 are located an inlet waterway 11, a water pump waterway 12, a microfiltration waterway 13, a wastewater waterway 14, and a purified water waterway 15. Generally, these waterways are integrated within the base plate. Outside the housing 1 are located a pre-filter element 2, a terminal inlet filter element 3, and a post-filter element 4.

[0027] It should be noted that in order to clearly and intuitively observe the structure inside the housing 1, Figure 1 The shell 1 in the figure only shows the bottom plate of the shell and some components integrated on the bottom plate. When the cover body covers the bottom plate, it is a complete shell, and the water channel integrated device can be used normally at this time.

[0028] According to an embodiment of the present application, the water inlet circuit 11 may include a water inlet 111 and a water inlet solenoid valve (not shown). The water inlet 111 of the water inlet circuit 11 is arranged above the bottom plate, and the water inlet 111 can be connected to municipal tap water. The water inlet solenoid valve is used to control the opening and closing of the water inlet circuit 11. The pre-filter element 2 has a water inlet, and the water inlet of the pre-filter element 2 is connected to the water inlet circuit 11. After a water source such as tap water enters the pre-filter element 2 through the water inlet circuit 11, the pre-filter element 2 performs the first filtration on the water supply. In an embodiment of the present application, the pre-filter element 2 may be an activated carbon filter element or a PP cotton filter element, and the pre-filter element 2 can filter out large particles such as mud, rust, insect eggs, and red worms in the tap water. The water filtered by the pre-filter element 2 can be called micro-filtered water, and micro-filtered water can be used for large-flow users such as washing vegetables and washing dishes. Therefore, the pre-filter cartridge 2 according to the present application has two water outlets, one of which is connected to the water pump waterway 12, and the other is connected to the microfiltration waterway 13. The microfiltration waterway 13 may include a microfiltration water outlet 131, which can be connected to the main faucet in the kitchen to meet the user's high-flow MF microfiltration water needs.

[0029] The water pump circuit 12 includes a water pump 121 having a water pump inlet 122 and a water pump outlet 123. Generally, the water pump 121 is arranged near the terminal water inlet filter 3 to pump water for the terminal water inlet filter 3 and maintain the water pressure at an ideal level when the water enters the terminal water inlet filter 3. Figure 1 The water pump inlet 122 and the water pump outlet 123 are respectively arranged on both sides of the bottom plate of the waterway plate housing 1.

[0030] The end water inlet filter element 3 has a water inlet, and the water inlet of the end water inlet filter element 3 is connected to the water pump outlet 123. The micro-filtered water after filtering by the pre-filter element 2 enters the end water inlet filter element 3, and the end water inlet filter element 3 is used to perform a second filtration on the water supply, and filtered water and wastewater will be produced after filtration. The end water inlet filter element 3 includes two water outlets, one of which is connected to the wastewater waterway 14, and the other is connected to the water inlet of the post-filter element 4. The wastewater waterway 14 includes a wastewater outlet 141 and a wastewater solenoid valve (not shown), which is used to control the opening and closing of the wastewater waterway 14. The wastewater generated by the end water inlet filter element 3 enters the wastewater waterway 14, and the filtered water (or permeated water) generated by the end water inlet filter element 3 enters the post-filter element 4. In an embodiment of the present application, the terminal water inlet filter element 3 may be a reverse osmosis filter element, a nanofiltration filter element or an ultrafiltration filter element, and the terminal water inlet filter element 3 may be used to effectively remove chlorine, heavy metals, bacteria, viruses, algae and suspended solids in water.

[0031] The post-filter element 4 has a water inlet and a water outlet. The filtered water after being filtered by the terminal water inlet filter element 3 enters the post-filter element 4, and is filtered for the third time by the post-filter element 4. The clean water (i.e., drinking water) produced after filtration enters the clean water circuit 15 through the water outlet, and flows out through the drinking water faucet for the user to drink. The clean water circuit 15 may include a clean water outlet 151 and a clean water solenoid valve (not shown), which is used to control the opening and closing of the clean water circuit 15. The clean water outlet 151 is connected to the drinking water faucet, and the clean water outlet 151 is arranged above the base plate. In an embodiment of the present application, the post-filter element 4 may be a granular activated carbon filter element or a compressed activated carbon filter element. The post-filter element 4 can effectively remove organic matter, residual chlorine and other radioactive substances in the water, and has the effects of decolorization, removing odor and further improving taste.

[0032] Combined with reference Figure 3A A TDS sensor 16 is further provided in the purified water channel 15. The TDS sensor 16 is used to measure the TDS concentration level of the purified water filtered by the post-filter 4. That is, the TDS sensor 16 is provided downstream of the post-filter 4. Of course, the number of TDS sensors in the present application is not limited to one. A TDS sensor (not shown) may also be provided upstream of the water pump 121 to perform a first on-site TDS measurement of the pre-filtered water supply.

[0033] In the prior art, because the water channel below or near the TDS sensor is at the same height as the water channel at other locations, the water flow rate is relatively low, causing bubbles to accumulate in the water channel near the TDS sensor, resulting in inaccurate TDS sensor detection values and large errors. The present application changes the design structure of the water channel below or near the TDS sensor, raising the water channel plate housing opposite the TDS sensor 161 upward to form a ramp structure, so that the height of the water channel near the TDS sensor 161 is smaller than the height of the water channel at other locations. As the water channel narrows, the water flow rate below the TDS sensor 161 increases, and bubble accumulation will not occur around the water channel near the TDS sensor 16.

[0034] Combined with reference Figure 3A 、 Figure 3B and Figure 4 ,in Figure 3A yes Figure 1 A cross-sectional view along the long side direction of the TDS sensor 16, Figure 3B yes Figure 3A The enlarged view of the middle part 3B, Figure 4 It is a cross-sectional view along line AA in FIG3 . Figure 3BA schematic diagram of a ramp structure according to an embodiment of the present application is shown. The waterway plate housing near the TDS sensor 16 and opposite to the TDS sensor 16 protrudes upward to form a ramp structure 5, wherein the general slope angle of the ramp structure can be between 10-80 degrees, and further, the general slope angle of the ramp structure can be between 30-60 degrees. Figure 3B As shown, the ramp structure 5 may include at least one linear slope section L. The slope angle of the linear slope section L may be between 10-80 degrees, preferably between 30-60 degrees.

[0035] In some embodiments of the present application, the TDS sensor 16 includes a TDS probe, which is located in the middle of the ramp structure and perpendicular to the water flow direction. Specifically, the TDS probe includes a negative probe 161 and a positive probe 162, and the two probes are located on the same straight line. Therefore, the negative probe 161 and the positive probe 162 can both be located in the middle of the ramp structure and perpendicular to the water flow direction. Figure 4 The arrows in the diagram indicate the direction of water flow.

[0036] It should be noted that the water channel integration device in this application can also be integrated with flow meters, solenoid valves, low-pressure switches, one-way valves and other components, which will not be repeated here.

Therefore, this application is intended to cover modifications and variations of the present application, and any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application shall be included within the scope of the claims of the present application and their equivalents.
