Those skilled in the art can set it by themselves according to actual use requirements. Such changes in specific application sites do not deviate from the basic principles of the present invention and belong to the scope of protection of the present invention.

In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0040] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "interconnected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection or a detachable connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0041] See also Figure 1 , Figure 1 Schematic diagram of the structure of the water purification device of the present invention. Figure 1As shown, the water purification device of the present invention includes a filtering system 1, a heating system 2 and a water purification pipeline 3. The filtering system 1 is connected to the heating system 2 through the water purification pipeline 3. Specifically, the water in the water purification pipeline 3 is filtered by the filtering system 1 and then enters the heating system 2 to change the water temperature to meet the user's various water needs.

[0042] Furthermore, the filtration system 1 includes a wastewater pipeline 101, a filtration component and a wastewater flow regulating component 102, the filtration component includes a pre-filter component 103 and a reverse osmosis filter component 104, the pre-filter component 103 and the reverse osmosis filter component 104 are arranged on the clean water pipeline 3 in sequence along the direction of water flow, the reverse osmosis filter component 104 includes a water inlet and two water outlets, the water inlet and the first water outlet of the reverse osmosis filter component 104 are connected to the clean water pipeline 3, the second water outlet of the reverse osmosis filter component 104 is connected to the wastewater pipeline 101, the wastewater flow regulating component 102 is arranged on the wastewater pipeline 101, and the wastewater flow regulating component 102 is configured to be able to adjust the wastewater flow of the wastewater pipeline 101.

[0043] It should be noted that the present invention does not impose any restrictions on the specific structure of the pre-filter component 103. For example, the pre-filter component 103 can be a multi-layer activated carbon or a multi-layer PP cotton filter layer (polypropylene melt-blown cotton filter layer). This is not restrictive. Those skilled in the art can set it according to the water quality of the water purification device. As a preferred embodiment, in this specific embodiment, the pre-filter component 103 includes a first PP cotton filter layer 1031, a carbon rod filter layer 1032, and a second PP cotton filter layer 1033. The first PP cotton filter layer 1031, the carbon rod filter layer 1032, and the second PP cotton filter layer 1033 are sequentially arranged on the water purification pipeline 3 along the direction of water flow. Among them, the first PP cotton filter layer 1031 and the second PP cotton filter layer 1033 can filter out impurities such as mud, suspended matter, colloids, organic matter, etc. in tap water. The activated carbon in the carbon rod filter element layer 1032 can have strong adsorption for many substances, and is mainly used to remove color, odor, residual chlorine, etc. in tap water, change the taste of water, and provide users with water quality of purified water level.

[0044] In addition, it should be noted that the present invention does not impose any restrictions on the specific structure of the wastewater flow regulating component 102. For example, the wastewater flow regulating component 102 may include a flow meter and a flow control valve. The flow meter detects the wastewater flow in the wastewater pipeline 101, and the flow control valve adjusts the flow in the wastewater pipeline, so that the wastewater flow in the wastewater pipeline 101 can be adjusted according to actual conditions to avoid impurities from accumulating in the reverse osmosis filter component 104 and ensure the service life of the reverse osmosis filter component 104. Of course, this is not restrictive. As long as the wastewater flow regulating component 102 can adjust the wastewater flow in the wastewater pipeline 101 to ensure the service life of the reverse osmosis filter component 104, those skilled in the art can set it according to actual conditions.

[0045] Preferably, if Figure 1 As shown, in this embodiment, the wastewater flow regulating component 102 includes a wastewater control valve 1021, a wastewater ratio fixing component 1022 and a switch control valve 1023, the wastewater ratio fixing component 1022 and the switch control valve 1023 are arranged in series, and the wastewater control valve 1021 is arranged in parallel with the wastewater ratio fixing component 1022 and the switch control valve 1023, that is, the wastewater control valve 1021 is arranged in parallel with the wastewater ratio fixing component 1022 and the switch control valve 1023 and is connected to the second outlet of the reverse osmosis filter component 104. In other words, part of the concentrated water filtered by the reverse osmosis filter component 104 is discharged along the wastewater pipeline 101 through the wastewater control valve 1021, and the other part is discharged after passing through the switch control valve 1023 and the wastewater ratio fixing component 1022. Among them, the wastewater control valve 1021 is a wastewater solenoid valve. The through hole of the wastewater solenoid valve is small and is prone to blockage after a long period of use. At this time, the wastewater solenoid valve will automatically reverse flush to remove the blockage. However, this will make it impossible for the concentrated water filtered out by the reverse osmosis filter component 104 to be discharged in time, and accumulate in the reverse osmosis filter component 104, resulting in a shortened service life of the reverse osmosis filter component 104; the setting of the switch control valve 1023 and the wastewater ratio fixing component 1022 can adjust the opening of the switch control valve 1023 so that the wastewater flow in the wastewater pipeline 101 is not affected by the wastewater solenoid valve and remains relatively stable, thereby effectively preventing impurities in the water from accumulating in the reverse osmosis filter component 104 and ensuring its service life.

[0046] It should be noted that the present invention does not impose any limitation on the specific structure of the wastewater ratio fixing component 1022 and the switch control valve 1023. For example, the switch control valve 1023 may be a ball valve or a butterfly valve. The wastewater ratio fixing component 1022 includes a main body, which is provided with a through hole, through which the wastewater in the wastewater pipe 101 can pass. Of course, the size of the through hole may be fixed or variable. Preferably, the size of the through hole may be variable, so that when the opening of the switch control valve 1023 is changed, the wastewater flow rate of the wastewater pipe 101 can be further accurately changed by controlling the size of the through hole. Of course, this is not restrictive, and those skilled in the art may set it according to actual conditions.

[0047] Furthermore, the filtration system 1 further includes a booster pump 105, which is disposed on the clean water pipeline 3 and between the filter assembly and the reverse osmosis filter element 104; the booster pump 105 can speed up the speed at which water passes through the reverse osmosis filter element 104, thereby ensuring the clean water flow rate of the clean water pipeline 3 and meeting the user's usage requirements. Preferably, in this specific embodiment, Figure 1 As shown, there are two groups of reverse osmosis filter components 104 and booster pumps 105, and the two groups of reverse osmosis filter components 104 and booster pumps 105 are arranged in parallel; the arrangement of the two groups of reverse osmosis filter components 104 and booster pumps 105 can further increase the clean water flow rate of the clean water pipeline 3, and can selectively open and close the two groups of reverse osmosis filter components 104 and booster pumps 105 according to the actual usage needs of the user, thereby changing the clean water flow rate of the clean water pipeline 3, and effectively improving the user experience.

[0048] It should be noted that the present invention does not impose any restrictions on the specific number of reverse osmosis filter components 104 and booster pumps 105. For example, the number of reverse osmosis filter components 104 and booster pumps 105 can also be three groups, four groups, or even more groups, which are not restrictive and can be set by those skilled in the art. In addition, it should be noted that the present invention does not impose any restrictions on the specific type and structure of the booster pump 105. The booster pump 105 can be a pneumatic booster pump, an air booster pump, or a water-type automatic booster pump, which are not restrictive and can be set by those skilled in the art according to the actual use requirements of the user.

[0049] Further preferably, the filtration system 1 further comprises a post-filter component 106, which is disposed on the purified water pipeline 3 and is disposed downstream of the reverse osmosis filter component 104 to improve the taste of purified water in the purified water pipeline 3. Of course, the specific structure and specific specifications of the post-filter component 106 are not restrictive. In the preferred embodiment, the post-filter component 106 is an activated carbon filter element to fully improve the taste of purified water and enhance the user experience.

[0050] Continue reading Figure 1 In this embodiment, the filtration system 1 further includes a low-pressure switch 107 and a high-pressure switch 108, which are arranged on the clean water pipeline 3, and the low-pressure switch 107 is arranged between the filter assembly and the booster pump 105, and the high-pressure switch 108 is arranged between the reverse osmosis filter component 104 and the post-filter component 106. Among them, the low-pressure switch 107 can effectively prevent the booster pump 105 from idling in the case of water failure, thereby ensuring the service life of the booster pump 105; the high-pressure switch 108 is closed when the water pressure in the clean water pipeline 3 reaches a peak value, and the power supply is cut off, so as to prevent the booster pump 105 from fully rotating and prevent the water purification device from being in a working state all the time. Of course, the specific structures of the low-pressure switch 107 and the high-pressure switch 108 are not restrictive, and those skilled in the art can set them according to actual conditions.

[0051] Furthermore, the filtration system 1 also includes a water quality probe 109, which is arranged on the clean water pipeline 3, and the water quality probe 109 is arranged downstream of the post-filter component 106; the water quality probe 109 can detect the water quality in the clean water pipeline 3, so that the technician can adjust the opening of the switch control valve 1023 and the flux of the wastewater ratio fixed component 1022 according to the water quality of the water purification device, that is, adjust the wastewater flow rate of the wastewater pipeline 101 to an appropriate flow rate to maximize the service life of the reverse osmosis filter component 104.

[0052] Preferably, the filtration system 1 further includes a sterilization component 110, which is disposed on the clean water pipeline 3 and is disposed downstream of the post-filtration component 106, specifically downstream of the water quality probe 109; the sterilization component 110 can kill residual microorganisms in the clean water to further ensure the user's water safety. Of course, the specific structure of the sterilization component 110 is not restrictive, and those skilled in the art can set it according to actual conditions; preferably, the sterilization component 110 is a flow-through ultraviolet sterilizer.

[0053] Further preferably, the filtration system 1 further comprises a pressure balancing component 111, which is disposed between the post-filtration component 106 and the sterilization component 110. Specifically, the pressure balancing component 111 is a pressure barrel, and a ball valve is disposed on the pressure barrel to adjust the pressure of the pressure barrel and the water pressure of the clean water pipeline 3.

[0054] In addition, the filtration system 1 further includes a one-way valve 112, which is disposed on the clean water pipeline 3 and between the first outlet of the reverse osmosis filter element 104 and the high-pressure switch 108. The one-way valve 112 is configured to only allow water in the clean water pipeline 3 to flow from the first outlet of the reverse osmosis filter element 104 to the high-pressure switch 108, so as to prevent water from flowing back to the reverse osmosis filter element 104. Of course, the specific type and specific structure of the one-way valve 112 are not restrictive, and those skilled in the art can set it according to actual conditions.

[0055] like Figure 1 As shown, the heating system 2 of the present invention includes a water outlet pipeline 201, a heating component and a temperature control component 202, wherein the heating component includes a heating member, the water outlet pipeline 201 is connected to the water purification pipeline 3 through the heating member, and the temperature control component 202 is configured to adjust the outlet water temperature of the water outlet pipeline 201. The temperature control component 202 can adjust the temperature of the water heated by the heating member, and can enable the water purification device to provide water of different temperatures without changing the internal structure, avoiding the need for after-sales personnel to repeatedly visit the site to change the internal structure of the water purification device, effectively meeting the user's water demand, reducing the user's use cost, and thus improving the user experience.

[0056] It should be noted that the present invention does not impose any restrictions on the specific structure of the heating component. For example, the heating component can be a heating tube or a heater. This is not restrictive. In the preferred embodiment, the heating component is a hot tank 203, and the hot tank 203 can heat the water inside it to a higher temperature (such as 85-100°C). In addition, it should be noted that the present invention does not impose any restrictions on the specific structure of the temperature control component 202. For example, the temperature control component 202 can be a condenser to reduce the temperature of the water flowing out of the hot tank 203, thereby achieving the purpose of regulating the water temperature. Of course, this is not restrictive, and those skilled in the art can set it according to actual conditions.

[0057] like Figure 1As shown, in this preferred embodiment, the water outlet pipeline 201 includes a first water outlet pipeline 2011, a second water outlet pipeline 2012 and a water inlet 2013, wherein the number of the water inlets 2013 is four to meet the water demand of the user; in addition, a water inlet control valve 2014 is provided at the water inlet 2013, and the water inlet control valve 2014 is configured to control the opening and closing state of the water inlet 2013. The first water outlet pipeline 2011 and the second water outlet pipeline 2012 are configured to be selectively connected to the water inlet 2013 through the temperature control component 202. The temperature control component 202 includes a temperature control component 2021, a first control valve 2022 and a second control valve 2023. A connecting branch is arranged between the first water outlet pipeline 2011 and the second water outlet pipeline 2012. The temperature control component 2021 is arranged on the first water outlet pipeline 2011, the first control valve 2022 is arranged on the connecting branch, and the second control valve 2023 is arranged on the second water outlet pipeline 2012. The first control valve 2022 is arranged to enable the first water outlet pipeline 2011 to be selectively connected to the water inlet 2013, and the second control valve 2023 is arranged to enable the second water outlet pipeline 2012 to be selectively connected to the water inlet 2013.

[0058] Specifically, when the first control valve 2022 is open and the second control valve 2023 is closed, Figure 1 The two water inlets 2013 above are warm water outlets, located Figure 1 The two water inlets 2013 below are water outlets; when the first control valve 2022 is closed and the second control valve 2023 is opened, Figure 1 The two water inlets below are warm water outlets. At this time, the four water inlets 2013 are all warm water outlets, that is, the original boiling water outlets are converted into warm water outlets through the temperature control component 202; in addition, when the temperature control component 2021 is not opened and the first control valve 2022 and the second control valve 2023 are opened, the four water inlets 2013 are all boiling water outlets; based on the above settings, the water purification device of the present invention avoids the purpose of changing the water outlet temperature of the water inlet by changing the internal structure, and is convenient for users to use.

[0059] It should be noted that the present invention does not impose any limitation on the specific structure of the temperature regulating component 2021, the first control valve 2022 and the second control valve 2023. For example, the temperature regulating component 2021 may be a condenser, and the first control valve 2022 and the second control valve 2023 may be ball valves or butterfly valves, which are not restrictive. In the present embodiment, the temperature regulating component 2021 is a temperature regulating valve, and the first control valve 2022 and the second control valve 2023 are both ball valves.

[0060] In addition, it should be noted that the present invention does not impose any restrictions on the specific structure of the hot tank 203. As a specific implementation method, Figure 1 As shown, the hot tank 203 includes a first water inlet and two water outlets. The water inlet of the hot tank 203 is connected to the clean water pipeline 3, the first water outlet of the hot tank 203 is connected to the first water outlet pipeline 2011, and the second water outlet of the hot tank 203 is connected to the second water outlet pipeline 2012.

[0061] Furthermore, the heating assembly further comprises a heat exchanger 204, which is connected to the water inlet and the first water outlet of the hot tank 203. The clean water pipeline 3 and the first water outlet pipeline 2011 are configured to be able to exchange heat through the heat exchanger 204, that is, at least a portion of the heat exchanger 204 is disposed on the clean water pipeline 3 and at least a portion of the heat exchanger 204 is disposed on the first water outlet pipeline 2011. The water in the clean water pipeline 3 absorbs heat in the heat exchanger 204 and enters the hot tank 203. The hot tank 203 heats the water and a portion of the water flows into the first water outlet pipeline 2011. The water in the first water outlet pipeline 2011 releases heat in the heat exchanger 204 and the temperature decreases. Then the water in the first water outlet pipeline 2011 enters the temperature adjustment component 2021 for further temperature adjustment to provide water at different temperatures. It should be noted that the specific structure of the heat exchanger 204 is not restrictive. For example, the heat exchanger 204 can be a shell and tube heat exchanger or a fin heat exchanger. Those skilled in the art can set it according to actual conditions.

[0062] In addition, in this embodiment, the heating system 2 further includes a temperature regulating branch 205, the temperature regulating branch 205 is connected to the first water outlet pipeline 2011 and the second water outlet pipeline 2012, the first end of the temperature regulating branch 205 is connected to the temperature regulating component 2021, and the second end of the temperature regulating branch 205 is connected between the second control valve 2023 and the second water outlet of the hot tank 203. The temperature regulating component 2021 can introduce the water in the second water outlet pipeline 2012 into the first water outlet pipeline 2011 to adjust the water temperature in the first water outlet pipeline 2011; conversely, when hot water is not needed, the temperature regulating component 2021 can also introduce the water in the first water outlet pipeline 2011 into the second water outlet pipeline 2012 to adjust the water temperature in the second water outlet pipeline 2012, so that the four water inlets 2013 all output warm water. Furthermore, a control valve (not shown) is provided on the temperature regulating branch 205, and the control valve can control the connection state of the temperature regulating branch 205. The temperature regulating branch 205 and the temperature regulating component 2021 are provided together to provide users with more water of different temperatures, fully meeting the water needs of users.

[0063] Further preferably, the heating system 2 further comprises a drainage pipeline 206, the hot tank 203 further comprises a third water outlet, and the drainage pipeline 206 is connected to the third water outlet of the hot tank 203; further, a drainage valve 2061 is provided on the drainage pipeline 206, and the drainage valve 2061 is configured to control the connection state of the drainage pipeline 206. The drainage pipeline 206 can discharge the water in the hot tank 203 when the user repairs the water purification device to avoid scalding of the maintenance personnel; and can also provide the user with higher temperature water at the fastest speed when the user needs more hot water.

[0064] Further preferably, the heating system 2 further comprises a sterilization branch 207, on which a sterilization water inlet control valve 2071 is provided, the sterilization branch 207 is connected to the water purification pipeline 3, the first end of the sterilization branch 207 is connected to the upstream of the heat exchanger 204, and the second end of the sterilization branch 207 is connected to the water inlet of the hot tank 203. The water in the sterilization branch 207 can directly enter the hot tank 203 for heating, and when the heat exchanger 204 is turned off, the water outlet pipeline 201 can be fully cleaned with the boiled water in the hot tank 203, which plays a role in cleaning and sterilization, thereby effectively ensuring the safety of water used by users.

[0065] Based on the above structural arrangement, the heating system of the present invention is used as follows:

[0066] Under normal use, the water inlet control valve 208 on the water purification pipeline 3 is in the open state, and the sterilization water inlet control valve 2071 is in the closed state. The water in the water purification pipeline 3 passes through the heat exchanger 204 and enters the hot tank 203. The hot tank 203 heats the water to a higher temperature, and the heated water enters the first water outlet pipeline 2011 and the second water outlet pipeline 2012. When the user needs warm water and boiling water at the same time, the first control valve 2022 is in the closed state, and the second control valve 2023 is in the open state. At this time, the water in the water purification pipeline 3 passes through the heat exchanger 204 and enters the hot tank 203. The hot tank 203 heats the water to a higher temperature, and the heated water enters the first water outlet pipeline 2011 and the second water outlet pipeline 2012. When the user needs warm water and boiling water at the same time, the first control valve 2022 is in the closed state, and the second control valve 2023 is in the open state. Figure 1 The two water inlets 2013 in the middle and upper part are warm water outlets, located Figure 1 The two water inlets 2013 in the middle and lower parts are boiling water outlets; at the same time, the temperature regulating branch 205 can be selectively connected according to the actual needs of the user to change the water outlet temperature of the two water inlets 2013 at the top. When the user only needs warm water, the first control valve 2022 is in an open state, and the second control valve 2023 is in a closed state. Similarly, the temperature regulating branch 205 is selectively connected. At this time, the four water inlets 2013 are all warm water inlets. When the user only needs boiling water, the first control valve 2022 and the second control valve 2023 are both in an open state, and the temperature regulating component 2021 and the temperature regulating branch 205 are in a disconnected state. At this time, the four water inlets 2013 are all boiling water inlets.

[0067] When the water purification device needs to be cleaned and sterilized, the water inlet control valve 208 on the water purification pipeline 3 is in a closed state, and the sterilization water inlet control valve 2071 is in an open state. The water in the water purification pipeline 3 enters the hot tank 203 through the sterilization branch 207. At this time, the heat exchanger 204 does not work, and the hot tank 203 heats the water to a higher temperature. The heated water enters the first water outlet pipeline 2011 and the second water outlet pipeline 2012. At this time, the first water outlet pipeline 2011 and the second water outlet pipeline 2012 are both filled with hot water. The first water outlet pipeline 2011 and the second water outlet pipeline 2012 are flushed with hot water to remove dirt in the pipelines and kill microorganisms in the pipelines, thereby effectively ensuring the user's water safety.

[0068] It should be noted that the above is only an exemplary usage, and the present invention does not impose any limitation on the specific usage of the water purification device, and those skilled in the art can set it according to actual conditions.

[0069] So far, the technical solutions of the present invention have been described in conjunction with the optional implementation modes shown in the accompanying drawings, but it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific implementation modes. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
