Description

Technical Field

[0001] The utility model relates to the technical field of water purification equipment, in particular to a water treatment device and a water treatment system. Background Art

[0002] Water purifiers can provide users with either room-temperature or hot water. This demand can be reflected in various applications, including drinking water, kitchen water, and water for brewing. Multiple water treatment systems are installed in water purifiers to thoroughly remove impurities from the water, ensuring that the water meets acceptable standards. These impurities include heavy metals and bacteria. With long-term use, the reverse osmosis treatment unit will experience a decrease in lifespan and cleaning performance due to prolonged exposure to impurities.

[0003] The cleaning capacity and service life of the reverse osmosis treatment unit directly affect the lifespan of the water purifier, water quality safety, and user experience. Therefore, it is necessary to improve the water purifier's ability to maintain the reverse osmosis treatment unit. Utility Model Content

[0004] The purpose of the utility model is to provide a water treatment device and a water treatment system, which can prolong the life of the water treatment device and improve the water quality safety of the water treatment device.

[0005] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0006] The utility model provides a water treatment device, comprising:

[0007] A booster pump, wherein the water inlet of the booster pump is connected to a raw water source;

[0008] a reverse osmosis treatment device, the reverse osmosis treatment device having a water inlet and a water outlet, wherein the water inlet of the reverse osmosis treatment device is connected to the water outlet of the booster pump via a clean water pipeline; and

[0009] At least one cleaning material generator, the cleaning material generator having a water inlet and a water outlet, wherein the water inlet of the cleaning material generator is connected to the water outlet of the booster pump via an inlet cleaning pipeline, and the water outlet of the cleaning material generator is connected to the water inlet of the reverse osmosis treatment device via an outlet cleaning pipeline; wherein the cleaning material is injected into the raw water as it passes through the cleaning material generator, and when the cleaning material passes through the reverse osmosis treatment device along with the raw water, the cleaning material is allowed to disturb or dissolve residual impurities in the reverse osmosis treatment device;

[0010] Among them, when the water treatment device is in working mode, the clean water pipeline is connected, and the inlet cleaning pipeline and the outlet cleaning pipeline are closed; when the water treatment device is in cleaning mode, the inlet cleaning pipeline and the outlet cleaning pipeline are connected, and the clean water pipeline is closed.

[0011] The utility model arranges a cleaning material generator between the booster pump and the reverse osmosis treatment device, and starts the cleaning mode when the water treatment device is not working, so that the inlet cleaning pipeline and the outlet cleaning pipeline located before and after the cleaning material generator are connected, so as to clean the reverse osmosis treatment device after the outlet cleaning pipeline of the cleaning material generator, thereby improving the cleaning effect of the reverse osmosis treatment device, increasing the service life of the reverse osmosis treatment device, and thus increasing the service life of the water purifier.

[0012] At the same time, when the cleanliness of the reverse osmosis treatment device is improved, the degree of purification of water by the reverse osmosis treatment device can be improved; thereby, pure and high-quality drinking water can be provided, and the water quality safety of the water purifier can be improved.

[0013] In one embodiment of the present invention, the cleaning substance is one of micro-nano bubbles, hydrogen peroxide and ozone gas.

[0014] In cleaning mode, the cleaning material flows with the water through the reverse osmosis treatment device. Micro-nano bubbles burst upon contact with the filter element of the reverse osmosis treatment device. The mechanical energy of the bursting micro-nano bubbles disturbs impurities remaining in the reverse osmosis treatment device, allowing the remaining impurities to enter the clean water and flow out of the reverse osmosis treatment device with the clean water. This not only simplifies the cleaning method but also achieves a good cleaning effect without the introduction of cleaning fluid. Hydrogen peroxide and ozone gas, acting as cleaning materials, oxidize and dissolve the remaining impurities adhering to the reverse osmosis treatment device, allowing the dissolved impurity reactants to flow out of the reverse osmosis treatment device along with the clean water, thus completely removing the remaining impurities in the reverse osmosis treatment device.

[0015] In one embodiment of the present invention, the water treatment device includes:

[0016] a first cleaning substance generator; and

[0017] a first solenoid valve and / or a second solenoid valve, wherein the first solenoid valve is disposed on the inlet cleaning pipeline and the second solenoid valve is disposed on the outlet cleaning pipeline; and

[0018] Wherein, when the water treatment device is in a cleaning mode, the first solenoid valve and the second solenoid valve are opened, and when the water treatment device is in a working mode, the first solenoid valve and the second solenoid valve are closed.

[0019] In cleaning mode, if only the first or second solenoid valve is provided, the corresponding solenoid valve is opened. If both the first and second solenoid valves are provided, they are opened simultaneously, allowing raw water to enter the inlet cleaning pipeline. The raw water then flows into the first cleaning agent generator, which injects the cleaning agent into the raw water. The raw water then carries the cleaning agent into the outlet cleaning pipeline and reaches the reverse osmosis treatment device. The cleaning agent removes any residual impurities remaining in the reverse osmosis treatment device.

[0020] In working mode, close the first solenoid valve and the second solenoid valve. When only the first solenoid valve or the second solenoid valve is set, close the corresponding solenoid valve to prevent raw water from entering the clean pipeline, so that the raw water can flow normally through the clean water pipeline and be output.

[0021] Providing a first solenoid valve and / or a second solenoid valve prevents the clean water inlet and outlet pipes from interfering with the normal output of purified water from the water treatment device, keeping the clean water pipes clean. Providing a first solenoid valve or a second solenoid valve can reduce component costs. Providing both a first solenoid valve and a second solenoid valve can prevent water from the clean water pipes from accidentally entering the clean water inlet and outlet pipes.

[0022] In one embodiment of the present invention, the water treatment device includes:

[0023] a first cleaning material generator, the water inlet of which is connected to the water outlet of the booster pump via a first cleaning inlet pipeline;

[0024] a first solenoid valve, disposed on the first inlet cleaning pipeline;

[0025] a second cleaning material generator, the water inlet of which is connected to the water outlet of the booster pump via a second cleaning introduction pipeline;

[0026] at most one second solenoid valve, disposed on the derivation cleaning pipeline, the second solenoid valve being connected to the water outlet of the first cleaning material generator and the water outlet of the second cleaning material generator, and the second solenoid valve being connected to the water inlet of the reverse osmosis treatment device; and

[0027] a third solenoid valve, disposed on the second inlet cleaning pipeline;

[0028] Wherein, in the cleaning mode of the water treatment device, the second solenoid valve is opened, and at the same time, either the first solenoid valve or the third solenoid valve is opened.

[0029] When the first cleaning product generator is operating, the first and second solenoid valves are opened, and the third solenoid valve is closed, allowing raw water to enter the first cleaning product generator through the first inlet cleaning pipeline, and the cleaning product in the first cleaning product generator is used to clean the reverse osmosis treatment device. When the second cleaning product generator is operating, the third and second solenoid valves are opened, allowing raw water to enter the second cleaning product generator through the second inlet cleaning pipeline, and the cleaning product in the second cleaning product generator is used to clean the reverse osmosis treatment device.

[0030] The two cleaning material generators are provided to clean the reverse osmosis treatment device in turn, which not only improves the cleaning strength but also reduces the use frequency of each cleaning pipeline within the same cleaning time, thereby increasing the service life of each cleaning pipeline.

[0031] In an embodiment of the present invention, the first cleaning material generator and the second cleaning material generator output different types of cleaning materials.

[0032] For example, the cleaning material type of the first cleaning material generator can be micro-nano bubbles, and the cleaning material type of the second cleaning material generator can be hydrogen peroxide or ozone gas. Through physical disturbance and chemical dissolution, the reverse osmosis treatment device is cleaned separately and in turn. Specifically, large-particle residual impurities and adhered residual impurities in the reverse osmosis treatment device are removed in rounds, thereby completely removing the residual impurities in the reverse osmosis treatment device.

[0033] In one embodiment of the present invention, the water treatment device includes a waste discharge pipeline, one end of which is connected to the water outlet of the reverse osmosis treatment device, and the other end of which serves as the waste discharge outlet of the water treatment device.

[0034] When the water treatment device is in cleaning mode, the clean water that passes through the reverse osmosis treatment device carries residual impurities in the reverse osmosis treatment device. If the clean water is output through the water purification outlet, there is a possibility of contaminating the water purification outlet, thereby affecting the water quality of the user. Therefore, the waste outlet and the waste discharge pipeline are separated separately. In the cleaning mode, the water output from the reverse osmosis treatment device is discharged through the waste discharge pipeline and the waste outlet. This not only avoids the waste discharge affecting the water quality of drinking water, but also improves the convenience of pipeline installation, so that the clean water is discharged silently.

[0035] In one embodiment of the present invention, the port of the cleaning pipeline and the port of the waste discharge pipeline are connected to the clean water pipeline through a three-way valve.

[0036] It is inevitable that pipelines will be contaminated and leave residues after long-term use. Clean pipelines are used to transport raw water with cleaning substances added, waste pipelines are used to transport clean water containing residual impurities in the reverse osmosis treatment device, and clean water pipelines are only used to transport raw water after filtration. Therefore, a three-way valve is set up. When a problem occurs in any pipeline, the corresponding pipeline can be replaced separately, thereby improving the maintainability of each component in the water treatment device and improving the quality of clean water.

[0037] In one embodiment of the present invention, the water treatment device includes a water outlet valve, one end of which is connected to the water outlet of the reverse osmosis treatment device through a pipeline, and the other end of which is connected to the water outlet of the water treatment device through a pipeline.

[0038] When the water outlet valve is activated, a start signal can be fed back to the control end, so that the control end switches the water treatment device from cleaning mode or sleep mode to working mode; in working mode, the raw water reaches the reverse osmosis treatment device through the water purification pipeline, and then outputs the purified raw water after passing through the reverse osmosis treatment device. The purified raw water then passes through the water outlet valve and is output as direct drinking water.

[0039] Setting a water outlet valve can not only improve the user's controllability of the water outlet, but also allow the control end of the water treatment device to feedback whether it is currently switching to the working mode based on whether the water outlet valve is open.

[0040] In one embodiment of the present invention, the water outlet valve is a solenoid valve or a manual opening and closing valve.

[0041] If the outlet valve is a manual on / off valve, it can be paired with a faucet, allowing the user to directly open the valve by turning the faucet. If the outlet valve is a solenoid valve, it can be paired with a start button, meaning the valve can be activated by pressing a button, providing a better user experience and faster feedback from the outlet valve to the controller.

[0042] In one embodiment of the present invention, the water treatment device includes a fourth solenoid valve, which is arranged on the water purification pipeline. In the working mode of the water treatment device, the fourth solenoid valve is opened, and in the cleaning mode of the water treatment device, the fourth solenoid valve is closed.

[0043] In the cleaning mode of the water treatment device, the fourth solenoid valve is closed, and at the same time the first solenoid valve, the second solenoid valve and the third solenoid valve are opened as required, closing the clean water pipeline and opening the inlet cleaning pipeline. Therefore, the raw water cannot pass through the clean water pipeline, but enters the inlet cleaning pipeline and passes through the first cleaning material generator or the second cleaning material generator. While cleaning the reverse osmosis treatment device, it prevents the cleaning water from being misdirected into the clean water pipeline and ensures that the clean water pipeline is not contaminated.

[0044] In one embodiment of the present invention, the filter material of the reverse osmosis treatment device is a reverse osmosis membrane.

[0045] In one embodiment of the present invention, the water treatment device includes a pre-filter structure, the water outlet of the pre-filter structure is connected to the water inlet of the booster pump through a pipeline, wherein the pre-filter structure is a multi-stage filtration structure, and the filter material or filter material of the pre-filter structure includes non-woven fabric and activated carbon to improve the filtering effect of the water treatment device.

[0046] Raw water passes through a multi-stage filtration structure, and various impurities in the raw water are gradually filtered out, which can improve the filtration rate of various impurities. Among them, when the raw water passes through the non-woven fabric, solid and soft particles in the raw water are removed, among which larger particle impurities are trapped on the fiber surface, while fine particles are captured in the deep layer of the filter material. Among them, when the raw water passes through the activated carbon, fine substances in the raw water, such as organic matter and heavy metals, synthetic detergents, bacteria, viruses and radioactive pollutants, are removed.

[0047] In one embodiment of the present utility model, the water treatment device includes a solenoid valve control module. When the water treatment device is in working mode, the solenoid valve control module controls the solenoid valve on the clean water pipeline to open, and controls the solenoid valve on the inlet cleaning pipeline and / or the outlet cleaning pipeline to close. When the water treatment device is in cleaning mode, the solenoid valve control module controls the solenoid valve on the clean water pipeline to close, and controls the solenoid valve on the inlet cleaning pipeline and / or the outlet cleaning pipeline to open.

[0048] In this embodiment, the solenoid valve control module controls the opening and closing of multiple solenoid valves to achieve automatic switching between cleaning mode and working mode. Specifically, in working mode, the first, second, and third solenoid valves are all closed, the inlet and outlet cleaning pipelines are closed, the fourth solenoid valve is opened, and the clean water pipeline is connected, thereby preventing raw water from passing through the inlet and outlet cleaning pipelines and preventing the mixing of purified pure water. In cleaning mode, the first, second, and third solenoid valves are all opened, the inlet and outlet cleaning pipelines are connected, the fourth solenoid valve is closed, and the clean water pipeline is closed, thereby preventing raw water containing impurities and cleaning liquid from flowing back into the clean water pipeline and contaminating the clean water pipeline.

[0049] In one embodiment of the present invention, the water treatment device includes:

[0050] A start button, when the water treatment device is used in a water purifier, the start button can be set on the water purifier housing;

[0051] a start sensor connected to the start button, wherein the start sensor is a pressure sensor, and when the start button is pressed, the start sensor outputs changing sensor data; and

[0052] The mode switching module is electrically connected to the start sensor and receives the sensor data. When the sensor data changes, the mode switching module switches the mode of the water treatment device and starts the solenoid valve control module.

[0053] When the start button is pressed, the pressing force is transmitted to the start sensor. The mode switching module receives the sensor data from the start sensor and generates a mode switching signal. Triggered by the mode switching signal, the water purification control system switches the water treatment device from non-operating mode to operating mode. Specifically, it switches the water treatment device from cleaning mode to operating mode. In operating mode, the solenoid valve control module controls the first, second, and third solenoid valves to close, and then controls the fourth solenoid valve and the outlet valve to open in sequence, allowing raw water to enter the cleaning pipeline and carry the cleaned materials through the reverse osmosis treatment device, completing the cleaning of the reverse osmosis treatment device.

[0054] In one embodiment of the present invention, when the water treatment device switches from the cleaning mode to the working mode, after the solenoid valve on the cleaning pipeline is closed, the solenoid valve control module controls the solenoid valve on the clean water pipeline to open.

[0055] Specifically, after confirming that the first solenoid valve, the second solenoid valve and the third solenoid valve are closed, that is, after closing the inlet cleaning pipeline and the outlet cleaning pipeline, the fourth solenoid valve is opened to connect the clean water pipeline, thereby avoiding the mixing of purified water and clean water and improving the drinking quality of direct drinking water.

[0056] The water treatment device provided by the present invention can realize automatic switching between the working mode and the cleaning mode, for example, by starting the mode switching process through a start button and a pressure sensor.

[0057] The utility model provides a water treatment system, wherein the water treatment system can be used in a water purifier, wherein the water treatment system comprises:

[0058] A water treatment device as described above, wherein the water treatment device can be installed in a water purifier housing; and

[0059] A control device is used to control the water treatment device to switch between a working mode and a cleaning mode.

[0060] As described above, the present invention provides a water treatment device and water treatment system that can provide pure, high-quality drinking water, and can improve the cleaning efficiency and cleaning effect of the reverse osmosis treatment device, thereby increasing the service life of the reverse osmosis treatment device, thereby increasing the service life of the water purifier and improving the water quality safety of the water purifier. Furthermore, the water treatment device and water treatment system provided by the present invention not only have a good cleaning effect on the reverse osmosis treatment device, but also have a simple cleaning operation, which can prevent the cleaning fluid from polluting the environment. Furthermore, the water treatment device and water treatment system provided by the present invention can reduce the user's maintenance operations, while improving the user experience while improving the quality of drinking water.

[0061] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0068] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0069] See also Figure 1 As shown, the present invention provides a water treatment device. The water treatment device includes a water purification device 100 and a water purification control system 200. The water purification device 100 includes a booster pump 110, a reverse osmosis treatment device 120, and a cleaning device 130. In this embodiment, the water inlet of the booster pump 110 is connected to a raw water source. The water outlet of the booster pump 110 is connected to the reverse osmosis treatment device 120 via a clean water pipeline. In the water treatment device's operating mode, raw water enters the reverse osmosis treatment device 120 through the clean water pipeline and is filtered. Remaining impurities in the raw water are filtered and removed. The raw water is then discharged from the water treatment device through a pipeline and used as user water. The water outlet of the booster pump 110 is connected to the water inlet of the cleaning device 130, and the water outlet of the cleaning device 130 is connected to the reverse osmosis treatment device 120. In the water treatment device's cleaning mode, raw water enters the cleaning device 130 via the clean water pipeline, and the cleaning device 130 adds cleaning substances to the raw water. The raw water then flows through the clean outlet pipe. As it passes through the reverse osmosis treatment unit 120, the cleaning agent agitates and removes any remaining particulate contaminants, or dissolves and removes any remaining adhesive matter, thereby completing the cleaning of the reverse osmosis treatment unit 120. The cleaned wastewater is then discharged through the waste pipe.

[0070] It should be noted that the present invention does not limit the source of raw water. In the present invention, the raw water source can come from, for example, a public water tank or a separate water tank. The raw water source can be drinking water or tap water. Furthermore, the raw water source is not limited to residential water; it can also be commercial water, industrial water, and so on.

[0071] See also Figures 1 to 3As shown, it should be noted that, in the present invention, the filter material of the reverse osmosis treatment device 120 is a filter membrane. And in the present embodiment, the filter material of the reverse osmosis treatment device 120 is a reverse osmosis membrane. The present invention does not limit the shape and type of the reverse osmosis membrane. For example, the reverse osmosis membrane can be an asymmetric membrane or a homogeneous membrane. For another example, the reverse osmosis membrane can be in an arc shape or a flat shape. Specifically, the arc shape is, for example, a cylindrical surface, a complete spherical surface, a partial spherical surface, an ellipsoidal surface, and the like. In the working mode of the water treatment device, the raw water is pressurized by the booster pump 110 and then passes through the reverse osmosis membrane, and impurities such as dissolved salts, colloids, microorganisms, and organic matter in the raw water are removed.

[0072] See also Figure 1 and Figure 2 As shown, in the present invention, the cleaning device 130 includes at least one cleaning material generator 131. In one embodiment of the present invention, the cleaning device 130 includes, for example, one cleaning material generator 131, and a first solenoid valve 132 and / or a second solenoid valve 133. Figure 2 As shown, the cleaning device 130 includes a first cleaning material generator 1311. In the present embodiment, the first cleaning material generator 1311 is a micro-nano bubble generator. The first cleaning material generator 1311 has a water inlet and a water outlet. The water inlet of the first cleaning material generator 1311 is connected to a first solenoid valve 132, and the water outlet of the first cleaning material generator 1311 is connected to a second solenoid valve 133. The first solenoid valve 132 is connected to the water outlet of the booster pump 110, and the second solenoid valve 133 is connected to the water inlet of the reverse osmosis treatment device 120. In the present embodiment, the first solenoid valve 132 is arranged on the introduction cleaning pipeline, and the second solenoid valve 133 is arranged on the derivation cleaning pipeline. In the cleaning mode of the water treatment device, the first solenoid valve 132 and the second solenoid valve 133 are opened, and the raw water is pressurized by the booster pump 110 and input into the introduction cleaning pipeline. Raw water passes through the first solenoid valve 132 and then the first cleaning agent generator 1311, where it is injected with micro-nano bubbles. The raw water, carrying the micro-nano bubbles, then passes through the second solenoid valve 133 and enters the reverse osmosis treatment device 120. In this embodiment, the micro-nano bubbles burst upon the surface of the reverse osmosis membrane, instantly releasing the mechanical energy generated by the explosion. This disturbs the contaminants on the reverse osmosis membrane surface, causing them to dislodge and be flushed away along with the raw water, thereby cleaning the reverse osmosis membrane. It should be noted that the cleaning device 130 may include both the first solenoid valve 132 and the second solenoid valve 133, or may include only the first solenoid valve 132 or only the second solenoid valve 133.

[0073] See also Figure 1 and Figure 3As shown, in another embodiment of the present invention, the cleaning device 130 includes, for example, two cleaning material generators 131, a first solenoid valve 132 and a third solenoid valve 134, and at most one second solenoid valve 133. Figure 3 As shown, the cleaning device 130 includes a first cleaning object generator 1311 and a second cleaning object generator 1312. In the present embodiment, the first cleaning object generator 1311 is a micro-nano bubble generator, and the second cleaning object generator 1312 is a hydrogen peroxide generator or an ozone generator. The hydrogen peroxide generator may also be referred to as a hydrogen peroxide generator. The first cleaning object generator 1311 and the second cleaning object generator 1312 respectively have a water inlet and a water outlet. In the present embodiment, the water inlet of the first cleaning object generator 1311 is connected to a first solenoid valve 132, and the water outlet of the first cleaning object generator 1311 is connected to a second solenoid valve 133. The first solenoid valve 132 is arranged on the first import cleaning pipeline. The water inlet of the second cleaning object generator 1312 is connected to a third solenoid valve 134, and the water outlet of the second cleaning object generator 1312 is connected to the second solenoid valve 133. The third solenoid valve 134 is arranged on the second import cleaning pipeline. The first solenoid valve 132 and the third solenoid valve 134 are connected to the water outlet of the booster pump 110, and the second solenoid valve 133 is connected to the water inlet of the reverse osmosis treatment device 120. In this embodiment, in the cleaning mode of the water treatment device, either the first solenoid valve 132 or the third solenoid valve 134 is open, and the second solenoid valve 133 is open. The first cleaning agent generator 1311 and the second cleaning agent generator 1312 alternately inject cleaning agent into the raw water, thereby completing the cleaning of the reverse osmosis treatment device 120. In this embodiment, during a single cleaning process of the water treatment device 100, only the first solenoid valve 132 or the third solenoid valve 134 can be closed, that is, only the first cleaning agent generator 1311 or the second cleaning agent generator 1312 can be used to clean the reverse osmosis membrane. Specifically, the first cleaning agent generator 1311 and the second cleaning agent generator 1312 can operate during a single cleaning process or in different cleaning batches. It should be noted that, in this embodiment, the second solenoid valve 133 may not be provided in the cleaning device 130 .

[0074] See also Figure 1 and Figure 3As shown, in another embodiment of the present invention, the order in which the first and third solenoid valves 132 and 134 are opened is not limited. For example, the first solenoid valve 132 is opened first, while the third solenoid valve 134 is closed. At this time, micro-nano bubbles are injected into the raw water via the first cleaning agent generator 1311. The mechanical energy of the bubbles' bursting action cleans particulate impurities from the reverse osmosis membrane. Next, the first solenoid valve 132 is closed, while the third solenoid valve 134 is opened. At this time, hydrogen peroxide or ozone gas is injected into the raw water via the second cleaning agent generator 1312. As the raw water passes through the reverse osmosis treatment unit 120, the hydrogen peroxide or ozone gas cleans the reverse osmosis membrane, dissolving any adhering substances. The raw water then carries away the dissolved adhering substances, thus completing the cleaning of the reverse osmosis membrane.

[0075] See also Figures 1 to 3 As shown, in the present invention, the water purification device 100 includes a fourth solenoid valve 140. The fourth solenoid valve 140 is disposed in the purified water pipeline, where the fourth solenoid valve 140 is connected to the water outlet of the booster pump 110 and the water inlet of the reverse osmosis treatment device 120. When the water treatment device is in operating mode, the fourth solenoid valve 140 is open, and the first solenoid valve 132 and the third solenoid valve 134 are closed. Raw water is discharged from the water outlet of the booster pump 110, passes through the purified water pipeline, the fourth solenoid valve 140, and then passes through the reverse osmosis treatment device 120. When the water treatment device is in a mode other than operating mode, such as when the water treatment device is in cleaning mode, the fourth solenoid valve 140 is closed.

[0076] See also Figures 1 to 3 As shown, in the present invention, the water treatment device includes a waste pipe, one end of which is connected to the water outlet of the reverse osmosis treatment device 120, and the other end of which serves as the waste outlet of the water treatment device. The waste outlet and the water outlet of the water treatment device are two independent pipe openings. In this embodiment, the clean water pipe is connected to the water outlet of the booster pump 110 and the water inlet of the reverse osmosis treatment device 120.

[0078] See also Figure 1 As shown, in the present invention, the water purification device 100 includes a pre-filter structure 180. The pre-filter structure 180 is connected to the raw water inlet and the water inlet of the booster pump 110. The raw water is initially filtered through the pre-filter structure 180 and then pressurized and discharged by the booster pump 110. In one embodiment of the present invention, the pre-filter structure 180 has a multi-stage filtration structure. In this embodiment, the pre-filter structure 180 is, for example, a two-stage filtration structure, specifically comprising a first-stage filtration structure and a second-stage filtration structure. The first-stage filtration structure first contacts the raw water and removes solid and soft particles from the raw water. Larger particles are trapped on the fiber surface, while fine particles are captured deep within the filter material. The present invention does not limit the shape of the first-stage filtration structure; it can be a plate-type filtration structure or a bag-type filtration structure. In this embodiment, the filter material of the first-stage filtration structure is, for example, non-woven filter cotton. In this embodiment, the second-stage filtration structure is connected to the water outlet of the first-stage filtration structure. The second-stage filtration structure further removes fine matter from the raw water, such as organic matter, heavy metals, synthetic detergents, bacteria, viruses, and radioactive contaminants. In this embodiment, the filter material of the second-stage filtration structure is, for example, activated carbon. In this embodiment, the water inlet of the booster pump 110 is connected to the water outlet of the multi-stage filtration structure to receive the raw water after preliminary filtration and increase the pressure of the raw water to compensate for the loss of flow rate after transmission and the multi-stage filtration structure, allowing the raw water to quickly pass through the reverse osmosis treatment device 120 for filtration, or to pass through the cleaning device 130 as high-pressure clean water through the reverse osmosis treatment device 120.

[0079] See also Figure 1As shown, in the present invention, the water purification device 100 includes a water outlet valve 190, which is connected to the water outlet of the reverse osmosis treatment device 120 and the water outlet of the water treatment device. In the water treatment device's operating mode, the water outlet valve 190 is open, and the purified raw water is discharged from the water treatment device's outlet. In other modes of the water treatment device, such as the cleaning mode of the water treatment device, the water outlet valve 190 is closed, and the waste pipe is open.

[0080] See also Figure 1 and Figure 4 As shown, in the present invention, the water treatment device includes a water purification control system 200. In one embodiment of the present invention, the water purification control system 200 includes a start sensor 210, a mode switching module 220 and a solenoid valve control module 220. The water treatment device also includes a start button, which can be a touch button or a remote control button. In this embodiment, the start button is set on the water treatment device, and the start sensor 210 is connected to the start button. The start sensor 210 can be a pressure sensor or an infrared sensor. For example, the start sensor 210 is a pressure sensor. When the start button is pressed, the pressing force is transmitted to the start sensor 210, and the mode switching module 220 receives the sensor data of the start sensor 210 and generates a mode switching signal. Under the triggering of the mode switching signal, the water purification control system 200 switches the water purification device 100 from the non-operating mode to the operating mode. In working mode, the solenoid valve control module 230 controls the first solenoid valve 132, the second solenoid valve 133 and the third solenoid valve 134 to close, and then controls the fourth solenoid valve 140 and the water outlet valve 190 to open in sequence, where the water outlet valve 190 can be a solenoid valve or a manual opening and closing valve.

[0081] See also Figure 1 and Figure 4As shown, the present invention also provides a water treatment system, comprising the above-mentioned water treatment device and a control device. The control device can control the water treatment device to automatically switch between a cleaning mode and an operating mode. It should be noted that the present invention does not limit the steps for switching the water treatment device from the operating mode to the non-operating mode. For example, in this embodiment, the control device can achieve the switch from the operating mode to the non-operating mode by limiting the water output. Specifically, after switching to the operating mode, when the water treatment device's single water output reaches a preset discharge volume, the mode switching module 220 automatically switches the water treatment device from the operating mode to the non-operating mode. For another example, in this embodiment, the control device can achieve the switch from the non-operating mode to the operating mode, and vice versa, by limiting the activation method of the activation sensor 210. Specifically, no activation button is provided, and the water outlet valve 190 is configured as a manual on / off valve. The activation sensor 210 is connected to the water outlet valve 190, and the sensor data received by the activation sensor 210 is different when the water outlet valve 190 is open and when the water outlet valve 190 is closed. When the outlet valve 190 is opened or closed, the start sensor 210 transmits the changed sensor data to the mode switching module 220. According to the difference in the sensor data, the mode switching module 220 generates a corresponding mode switching signal, and the water purification device 100 switches from the non-operating mode to the operating mode, or switches from the operating mode to the non-operating mode. In the operating mode, the solenoid valve control module 230 completes the control of the multiple solenoid valves. For another example, the switching from the operating mode to the non-operating mode can be completed by setting multiple start buttons and the start sensor 210. Specifically, after the first start button is pressed, the water purification device 100 switches to the operating mode, and after the second start button is pressed, the water purification device 100 switches to the non-operating mode, and so on.

[0082] See also Figure 4As shown, in one embodiment of the present invention, the mode switching module 220 and the solenoid valve control module 230 in the water purification control system 200 can be integrated on a chip in the form of an integrated circuit, and the chip is electrically connected to the start sensor 210 to receive the sensor data of the start sensor 210. A processor can also be provided on the chip. The processor can be a general-purpose processor, including a central processing unit (CPU), a network processor (NP), etc. The processor can also be a digital signal processor (DSP), an application-specific integrated circuit (ASIC) or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components. The processor can regulate the working process of the mode switching module 220 and the solenoid valve control module 230. In one embodiment of the present invention, the working process of the mode switching module 220 and the solenoid valve control module 230 can be regulated by circuits and signals. In other embodiments of the present invention, the water purification function of the water treatment system can also be implemented through software logic. Specifically, by editing firmware and burning the firmware into memory, when the water treatment system is operating, the processor calls and executes the firmware in the memory to implement the corresponding water purification function. In this embodiment, the memory can be integrated on the chip or provided on the same circuit board as the chip, and the memory is electrically connected to the processor.
