Description

TECHNICAL FIELD

[0001] The utility model relates to water purification technical field, and specifically provide a water purification equipment. BACKGROUND

[0002] With the improvement of people's living standards, people's demand for drinking water is also higher and higher. Water purification equipment such as water purifier, water purification and integrated machine gradually becomes the necessary drinking water facilities in people's daily life.

[0003] After a long time of use, the dirt in the water will adhere to the reverse osmosis membrane filter element, affecting the water production rate of the water purification equipment, thereby affecting the service life of the reverse osmosis membrane filter element. After the water purification equipment is used for a period of time, the dirt adhering to the surface of the reverse osmosis membrane filter element can be removed by cleaning the reverse osmosis membrane filter element with a cleaning agent, thereby prolonging the service life of the reverse osmosis membrane filter element.

[0004] In the prior art, after the reverse osmosis membrane filter element is cleaned by the cleaning assembly, a small amount of cleaning agent will penetrate into the pure water end of the reverse osmosis membrane filter element. Although the cleaning agent used at present is harmless to the human body, as people's requirements for drinking water are getting higher and higher, the small amount of cleaning agent remaining after cleaning will still affect the user's experience. SUMMARY

[0005] The utility model aims to at least in a certain extent solve the above technical problem, that is, at least in a certain extent solve the problem that the existing water purification equipment has the risk of cleaning agent remaining after cleaning by the cleaning assembly, resulting in poor user experience.

[0006] In a first aspect, the utility model provides a water purification equipment, which comprises: the water purification equipment comprises: a reverse osmosis membrane filter element; a water inlet main path in communication with the water inlet end of the reverse osmosis membrane filter element; a cleaning assembly having a cleaning outlet and a cleaning agent storage member, the cleaning agent storage member is used to store a cleaning agent, the cleaning outlet can be in communication with the water inlet end of the reverse osmosis membrane filter element to deliver cleaning liquid to the reverse osmosis membrane filter element, thereby cleaning the reverse osmosis membrane filter element; and a pure water water member; wherein the water purification equipment is arranged to deliver the water in the pure water end of the reverse osmosis membrane filter element to the pure water water member for the user to drink, and the water purification equipment is also arranged to discharge the water in the pure water end of the reverse osmosis membrane filter element to the outside of the water purification equipment to prevent the water flowing out of the pure water end of the reverse osmosis membrane filter element from entering the pure water water member.

[0007] In the preferred technical scheme of the above water purification equipment, the water purification equipment further comprises a waste water outlet pipe in communication with the waste water end of the reverse osmosis membrane filter element, and the pure water end of the reverse osmosis membrane filter element can selectively communicate with the pure water water member or the waste water outlet pipe.

[0008] In the preferred embodiment of the above-mentioned water purification equipment, the water purification equipment further includes a pure water outlet pipe, a drain pipe, and a drain valve. The pure water end of the reverse osmosis membrane filter element is connected to the pure water user component through the pure water outlet pipe. One end of the drain pipe is connected to the pure water outlet pipe, and the other end of the drain pipe is connected to the wastewater outlet pipe. The drain valve is installed on the drain pipe and is used to control the opening and closing of the drain pipe. Alternatively, the water purification equipment further includes a pure water outlet pipe, a drain pipe, and a reversing valve. The first port of the reversing valve is connected to the pure water end of the reverse osmosis membrane filter element, the second port of the reversing valve is connected to the pure water outlet pipe, and the third port of the reversing valve is connected to the first end of the drain pipe. The first port of the reversing valve can selectively connect to the second port or the third port, wherein the second end of the drain pipe is connected to the wastewater outlet pipe.

[0009] In the preferred embodiment of the above-mentioned water purification equipment, the water purification equipment further includes a water quality detection component, which is used to detect the water quality information of the pure water end of the reverse osmosis membrane filter element.

[0010] In the preferred embodiment of the above-mentioned water purification equipment, the water quality detection component includes at least one of a pH sensor or a TDS sensor; and / or, the water quality detection component is communicatively connected to the drain valve or the reversing valve.

[0011] In the preferred embodiment of the above-mentioned water purification equipment, the water purification equipment further includes a wastewater valve and an impurity collection component installed on the wastewater outlet pipe. The impurity collection component is located upstream of the wastewater valve and is used to collect dirt inside the wastewater outlet pipe.

[0012] In the preferred embodiment of the above-mentioned water purification equipment, the cleaning component further has a cleaning inlet, which is connected to the main water inlet, so that water in the main water inlet enters the cleaning agent storage component to form a cleaning liquid. The cleaning outlet is connected to the main water inlet, so that the cleaning liquid in the cleaning agent storage component enters the reverse osmosis membrane filter element through the main water inlet.

[0013] In the preferred embodiment of the above-mentioned water purification equipment, the cleaning component includes a cleaning pipeline and a cleaning valve and a cleaning agent storage component disposed on the cleaning pipeline. The two ends of the cleaning pipeline respectively form the cleaning inlet and the cleaning outlet. The cleaning agent storage component is located downstream of the cleaning valve and is used to store acidic or alkaline cleaning agents. Alternatively, the cleaning component includes at least two parallel cleaning pipelines, a cleaning valve and a cleaning agent storage component disposed on each of the cleaning pipelines. The first ends of the plurality of cleaning pipelines converge to form the cleaning inlet, and the second ends of the plurality of cleaning pipelines converge to form the cleaning outlet. The cleaning agent storage component is located downstream of the cleaning valve, and the cleaning agent storage component on each of the cleaning pipelines is used to store different types of cleaning agents.

[0014] In the preferred embodiment of the above-mentioned water purification equipment, the cleaning component further includes a one-way valve, which is disposed on the cleaning pipeline and located at the downstream end of the cleaning agent storage component. The one-way valve is configured to prevent water in the main inlet pipeline from entering the cleaning agent storage component through the cleaning outlet.

[0015] In the preferred embodiment of the above-mentioned water purification equipment, the water purification equipment further includes a booster pump, which is installed on the main water inlet and located upstream of the clean outlet; and / or, the water purification equipment further includes a pre-filter unit, the outlet of which is connected to the main water inlet, and the clean inlet is located downstream of the pre-filter unit.

[0016] When the water purifier is in normal water production mode, the water from the pure water end of the reverse osmosis membrane filter cartridge is delivered to the pure water consumption component for user drinking. After the cleaning component has cleaned the reverse osmosis membrane filter cartridge, the water purifier can also discharge the pure water containing a small amount of detergent that has permeated into the pure water end of the reverse osmosis membrane filter cartridge to the outside of the water purifier, thereby removing the small amount of residual detergent and helping to achieve zero additives and zero chemical pollution, greatly improving the user experience. At the same time, when the water purifier is not used for a long time, the water from the pure water end of the reverse osmosis membrane filter cartridge can also be discharged to the outside of the water purifier, thereby preventing water with a high TDS from the pure water end of the reverse osmosis membrane filter cartridge from entering the pure water consumption component, solving the problem of "high TDS value of the first cup of water" in the water purifier.

[0017] Furthermore, by setting the pure water end of the reverse osmosis membrane filter cartridge to selectively connect to the pure water component or the wastewater outlet pipe, the internal piping connection of the water purification equipment can be simplified, and the water from the pure water end of the reverse osmosis membrane filter cartridge can be discharged without the need for additional piping.

[0018] Furthermore, by setting up water quality detection components, the water quality information of the pure water end of the reverse osmosis membrane filter element can be accurately detected. Based on the water quality information of the pure water end of the reverse osmosis membrane filter element, the pure water end of the reverse osmosis membrane filter element can be selectively connected to the pure water use component or the wastewater outlet pipe. This not only helps to achieve zero additives and zero chemical pollution, but also saves water resources and further improves the user experience.

[0019] Furthermore, by setting up an impurity collection component, after the cleaning solution finishes cleaning the reverse osmosis membrane filter element, the dirt removed is discharged along with the cleaning solution through the wastewater outlet pipe. The impurity collection component can collect the dirt removed, preventing the dirt from clogging the wastewater valve and extending the service life of the wastewater valve.

[0020] Furthermore, by configuring the water quality detection component to communicate with the drain valve or reversing valve, the pure water end of the reverse osmosis membrane filter element can be selectively connected to the pure water use component or wastewater outlet pipe by adjusting the drain valve or reversing valve based on the detection results of the water quality detection component. This makes the water purification equipment more intelligent and further enhances the user experience.

[0021] Furthermore, compared to setting the cleaning component to have only a cleaning outlet, setting the cleaning component to have both a cleaning inlet and a cleaning outlet allows the cleaning component to fill water into the cleaning inlet to form cleaning fluid during cleaning. This avoids storing a large amount of cleaning fluid in the cleaning agent storage component, which would result in an excessively large cleaning component, and further improves the user experience.

[0022] Furthermore, by installing a check valve, when the water purification equipment is in normal water production mode, it can prevent water in the main inlet pipe from flowing back into the detergent storage component, thereby avoiding the detergent from dissolving and entering the reverse osmosis membrane filter element under normal water production mode. At the same time, since the cost of a check valve is significantly lower than that of a control valve, compared with installing a control valve on the cleaning pipeline, installing a check valve to prevent water in the main inlet pipe from entering the detergent storage component through the cleaning outlet can further save the cost of the water purification equipment.

[0030] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

These are used merely for ease of description and do not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0032] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "setting," and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0033] In view of the problem mentioned in the background art that existing water purification equipment may have detergent residue after cleaning with cleaning components, resulting in a poor user experience, this utility model provides a water purification device.

[0034] Specifically, please refer toFigures 1 to 4 , Figure 1 This is a schematic diagram of the structure of a first embodiment of the water purification equipment of this utility model; Figure 2 This is a schematic diagram of the structure of a second embodiment of the water purification equipment of this utility model; Figure 3 This is a schematic diagram of the structure of Embodiment 3 of the water purification equipment of this utility model;

[0035] Figure 4 This is a schematic diagram of the structure of Embodiment 4 of the water purification equipment of this utility model.

[0036] like Figures 1 to 4 As shown, the water purification equipment of this utility model includes a reverse osmosis membrane filter element 2, a main water inlet 1, a cleaning component, and a pure water component 51.

[0037] The main inlet water line 1 is connected to the inlet end of the reverse osmosis membrane filter element 2. The cleaning component has a cleaning outlet 302 and a cleaning agent storage component 33. The cleaning agent storage component 33 is used to store cleaning agent. The cleaning outlet 302 can be connected to the inlet end of the reverse osmosis membrane filter element 2 so as to deliver cleaning liquid into the reverse osmosis membrane filter element 2, thereby cleaning the reverse osmosis membrane filter element 2.

[0038] The water purification equipment is configured to deliver water from the pure water end of the reverse osmosis membrane filter element 2 to the pure water consumption component 51 for users to drink. The water purification equipment is also configured to discharge water from the pure water end of the reverse osmosis membrane filter element 2 to the outside of the water purification equipment to prevent water flowing out from the pure water end of the reverse osmosis membrane filter element 2 from entering the pure water consumption component 51.

[0039] With this setup, when the water purifier is in normal water production mode, the pure water from the reverse osmosis membrane filter 2 is delivered to the pure water component 51 for user drinking. After the cleaning component has finished cleaning the reverse osmosis membrane filter 2, the water purifier can also discharge the pure water containing a small amount of detergent that has permeated to the pure water end of the reverse osmosis membrane filter 2 to the outside of the water purifier, thereby removing the small amount of residual detergent. This helps to achieve zero additives and zero chemical pollution, greatly improving the user experience.

[0040] It should be noted that the water purification equipment is also designed to discharge the water from the pure water end of the reverse osmosis membrane filter element 2 to the outside of the water purification equipment to prevent the water flowing out from the pure water end of the reverse osmosis membrane filter element 2 from entering the pure water consumption component 51. When the water purification equipment is not used for a long time, it can also prevent the water with a high TDS at the pure water end of the reverse osmosis membrane filter element 2 from entering the pure water consumption component 51, thus solving the problem of "high TDS value of the first cup of water" in the water purification equipment.

[0041] It should also be noted that, in practical applications, those skilled in the art do not impose any limitations on the specific configuration type of the pure water component 51, as long as it can output pure water from the reverse osmosis membrane filter 2 for user consumption. For example, the pure water component 51 can be configured as a pure water tank, with the pure water filtered by the reverse osmosis membrane filter 2 directly delivered to the pure water tank for user consumption. Alternatively, the pure water component 51 can be configured as a post-filter, with the pure water filtered by the reverse osmosis membrane filter 2 delivered to the post-filter to improve the taste before being delivered to the user. Or, the pure water component 51 can be configured as a water outlet component (water spout or faucet), with the pure water filtered by the reverse osmosis membrane filter 2 flowing directly from the water outlet component (water spout or faucet), etc. Such adjustments and changes to the specific configuration type of the pure water component 51 do not deviate from the principle and scope of this utility model and should all be included within the protection scope of this utility model.

[0042] Preferably, such as Figures 1 to 4 As shown, the pure water component 51 includes a post-filter cartridge. Pure water filtered by the reverse osmosis membrane cartridge 2 is delivered to the post-filter cartridge to improve the taste before being supplied to the user for drinking.

[0043] It should be noted that in practical applications, after the cleaning component has finished cleaning the reverse osmosis membrane filter element 2, the water from the pure water end of the reverse osmosis membrane filter element 2 can be directly discharged into the wastewater outlet pipe 21 of the water purification equipment, and then discharged to the outside of the water purification equipment through the wastewater outlet pipe 21. Alternatively, the water from the pure water end of the reverse osmosis membrane filter element 2 can be directly discharged into the wastewater outlet of the water purification equipment, thereby discharging the pure water containing cleaning agent to the outside of the water purification equipment. Or, the water from the pure water end of the reverse osmosis membrane filter element 2 can be directly discharged into the sewer in the user's usage scenario, thereby discharging the pure water containing cleaning agent to the outside of the water purification equipment, and so on. Such adjustments and changes to the specific discharge method of discharging the water from the pure water end of the reverse osmosis membrane filter element 2 to the outside of the water purification equipment do not deviate from the principle and scope of this utility model, and should all be included within the protection scope of this utility model.

[0044] Preferably, such as Figures 1 to 4 As shown, the water purification equipment also includes a wastewater outlet pipe 21, which is connected to the wastewater end of the reverse osmosis membrane filter element 2. The pure water end of the reverse osmosis membrane filter element 2 can be selectively connected to the pure water component 51 or the wastewater outlet pipe 21.

[0045] With this setup, after the cleaning component finishes cleaning the reverse osmosis membrane filter element 2, the pure water end of the reverse osmosis membrane filter element 2 is first connected to the wastewater outlet pipe 21. This allows water containing detergent residue flowing from the pure water end of the reverse osmosis membrane filter element 2 to be discharged into the wastewater outlet pipe 21, and then discharged to the outside of the water purification equipment. After the water containing detergent residue is completely discharged, the pure water end of the reverse osmosis membrane filter element 2 is then connected to the pure water component 51. This facilitates the delivery of pure water filtered by the reverse osmosis membrane filter element 2 to the pure water component 51 for user drinking. Furthermore, by setting the pure water end of the reverse osmosis membrane filter element 2 to selectively connect to either the pure water component 51 or the wastewater outlet pipe 21, the internal piping connection of the water purification equipment can be simplified, and the water from the pure water end of the reverse osmosis membrane filter element 2 can be discharged without the need for additional piping.

[0046] Preferably, such as Figures 1 to 4 As shown, the water purification equipment of this utility model also includes a wastewater valve 211, which is installed on the wastewater outlet pipe 21.

[0047] It should be noted that, in practical applications, this utility model does not impose any restrictions on the specific connection method of selectively connecting the pure water end of the reverse osmosis membrane filter element 2 to the pure water consumption component 51 or the wastewater outlet pipe 21, as long as it enables the pure water end of the reverse osmosis membrane filter element 2 to selectively connect to the pure water outlet pipe 5 or the wastewater outlet pipe 21.

[0048] In one specific embodiment, such as Figure 1 and Figure 2 As shown, the water purification equipment also includes a pure water outlet pipe 5, a drain pipe 22, and a drain valve 221. The pure water end of the reverse osmosis membrane filter element 2 is connected to the pure water user component 51 through the pure water outlet pipe 5. One end of the drain pipe 22 is connected to the pure water outlet pipe 5, and the other end of the drain pipe 22 is connected to the wastewater outlet pipe 21. The drain valve 221 is installed on the drain pipe 22 and is used to control the opening and closing of the drain pipe 22.

[0049] In another specific embodiment, such as Figure 3 and Figure 4 As shown, the water purification equipment also includes a pure water outlet pipe 5, a drain pipe 22, and a reversing valve 23. The first port of the reversing valve 23 is connected to the pure water end of the reverse osmosis membrane filter element 2, the second port of the reversing valve 23 is connected to the pure water outlet pipe 5, the third port of the reversing valve 23 is connected to the first end of the drain pipe 22, the first port of the reversing valve 23 can be selectively connected to the second port or the third port, and the second end of the drain pipe 22 is connected to the wastewater outlet pipe 21.

[0050] It should be noted that in practical applications, when water containing detergent residue from the pure water end of the reverse osmosis membrane filter element 2 is transported to the outside of the water purification equipment, it can be determined based on experience whether to transport water containing detergent residue to the outside of the water purification equipment. Alternatively, the water quality information of the pure water flowing out from the pure water end of the reverse osmosis membrane filter element 2 can be detected to determine whether to transport water containing detergent residue to the outside of the water purification equipment. Such flexible adjustments and changes do not deviate from the principle and scope of this utility model and should be included within the protection scope of this utility model.

[0051] Preferably, such as Figures 1 to 4 As shown, the water purification equipment of this utility model also includes a water quality detection component 52, which is used to detect the water quality information of the pure water end of the reverse osmosis membrane filter element 2.

[0052] By setting up the water quality detection component 52, the water quality information of the pure water end of the reverse osmosis membrane filter element 2 can be accurately detected. Then, based on the water quality information of the pure water end of the reverse osmosis membrane filter element 2, the pure water end of the reverse osmosis membrane filter element 2 can be selectively connected to the pure water use component 51 or the wastewater outlet pipe 21. This not only removes the small amount of residual cleaning agent, but also saves water and further improves the user experience.

[0053] It should be noted that this utility model does not limit the specific configuration type of the water quality detection component 52. For example, the water quality detection component 52 can be configured as a pH sensor, or as a TDS sensor, or as both a pH sensor and a TDS sensor, etc. Such adjustments and changes to the specific configuration type of the water quality detection component 52 do not deviate from the principle and scope of this utility model and should be included within the protection scope of this utility model.

[0054] Preferably, the water quality detection component 52 includes at least one of a pH sensor or a TDS sensor.

[0055] It should be noted that, in practical applications, those skilled in the art can place the water quality detection component 52 on the pure water outlet pipe 5, or on the drain pipe 22, or between the reverse osmosis membrane filter element 2 and the reversing valve 23, etc. Such adjustments and changes to the specific placement of the water quality detection component 52 do not deviate from the principle and scope of this utility model, and should all be included within the protection scope of this utility model.

[0056] For example, such as Figure 1 and Figure 2 As shown, the water quality testing component 52 is installed on the pure water outlet pipe 5.

[0057] For example, such as Figure 3 and Figure 4 As shown, the water quality detection component 52 is installed between the reverse osmosis membrane filter element 2 and the reversing valve 23.

[0058] Preferably, the water quality detection component 52 is communicatively connected to the drain valve 221 or the reversing valve 23.

[0059] With this setup, the pure water end of the reverse osmosis membrane filter element 2 can be selectively connected to the pure water component 51 or the wastewater outlet pipe 21 by adjusting the drain valve 221 or the reversing valve 23 based on the detection results of the water quality detection component 52, making the water purification equipment more intelligent and further improving the user experience.

[0060] It should be noted that, in practical applications, those skilled in the art can configure the water quality detection component 52 and the drain valve 221 (or the reversing valve 23) to communicate with the controller of the water purification equipment, or they can configure the water quality detection component 52 and the drain valve 221 (or the reversing valve 23) to communicate with the user's mobile device (tablet or mobile phone), etc. Such adjustments and changes to the specific connection method of the water quality detection component 52 and the drain valve 221 or the reversing valve 23 do not deviate from the principle and scope of this utility model, and should be included within the protection scope of this utility model.

[0061] Preferably, the water quality detection component 52 and the drain valve 221 (or reversing valve 23) are both connected to the controller of the water purification equipment.

[0062] Preferably, the water purification equipment also includes a wastewater valve 211 and an impurity collection component 212 installed on the wastewater outlet pipe 21. The impurity collection component 212 is located upstream of the wastewater valve 211 and is used to collect dirt inside the wastewater outlet pipe 21.

[0063] With this setup, after the cleaning solution finishes cleaning the reverse osmosis membrane filter element 2, the dirt removed is discharged along with the cleaning solution through the wastewater outlet pipe 21. The impurity collection component 212 can collect the dirt removed, preventing the dirt from clogging the wastewater valve 211 and extending the service life of the wastewater valve 211.

[0064] It should be noted that, in practical applications, this utility model does not impose any limitations on the specific configuration type of the impurity collection component 212, as long as it can collect the dirt inside the wastewater outlet pipe 21. For example, the impurity collection component 212 can be configured to include a box and a filter screen disposed inside the box, with the filter screen intercepting and collecting the dirt in the cleaning liquid into the box. Alternatively, the impurity collection component 212 can be configured as a filter screen pocket installed inside the wastewater outlet pipe, etc. Such adjustments and changes to the specific configuration type of the impurity collection component 212 do not deviate from the principle and scope of this utility model and should all be included within the protection scope of this utility model.

[0065] Preferably, the impurity collection component 212 is configured to include a box body and a filter screen (not shown) disposed in the box body. The box body has a collection chamber, and the filter screen is used to intercept dirt in the cleaning liquid and collect it into the collection chamber.

[0066] Preferably, the box body is also provided with a drain outlet and a compartment door. The drain outlet is connected to the collection chamber, and the compartment door is located at the drain outlet and is used to open or close the drain outlet.

[0067] This design makes it easy to open the compartment door and clean out the dirt inside the collection chamber, preventing bacteria growth and further improving the user experience.

[0068] It should be noted that, in practical applications, those skilled in the art can configure the reverse osmosis membrane filter element 2 to have two inlets, with the main inlet 1 and the cleaning outlet 302 respectively connected to the two inlets. Alternatively, the cleaning outlet 302 can be configured to be connected to the main inlet 1, with the cleaning component delivering the cleaning liquid to the reverse osmosis membrane filter element 2 through the main inlet 1, and so on. Such flexible adjustments and changes do not deviate from the principles and scope of this utility model and should all be included within the protection scope of this utility model.

[0069] It should also be noted that, in practical applications, this utility model does not limit the specific configuration type of the cleaning component. For example, the cleaning component can be configured to have only a cleaning outlet 302, that is, a large amount of cleaning liquid can be directly stored in the cleaning agent storage component 33. When the reverse osmosis membrane filter element 2 needs to be cleaned, the cleaning agent stored in the cleaning agent storage component 33 flows out from the cleaning outlet 302 and is transported to the reverse osmosis membrane filter element 2. Alternatively, the cleaning component can be configured to include a cleaning pipeline 31 and a cleaning agent storage component 33 disposed on the cleaning pipeline 31. The two ends of the cleaning pipeline 31 form a cleaning inlet 301 and a cleaning outlet 302, respectively. Water is injected into the cleaning inlet 301 to form cleaning liquid in the cleaning agent storage component 33, etc. Such adjustments and changes to the specific configuration type of the cleaning component do not deviate from the principle and scope of this utility model and should all be included within the protection scope of this utility model.

[0070] Preferably, such as Figures 1 to 4 As shown, the cleaning component also has a cleaning inlet 301, which is connected to the main water inlet 1 so that water in the main water inlet 1 enters the cleaning agent storage component 33 to form cleaning liquid. The cleaning outlet 302 is connected to the main water inlet 1 so that the cleaning liquid in the cleaning agent storage component 33 enters the reverse osmosis membrane filter element 2 through the main water inlet 1.

[0071] With this configuration, compared to setting the cleaning component to have only a cleaning outlet 302, setting the cleaning component to have both a cleaning inlet 301 and a cleaning outlet 302 allows the cleaning component to inject water into the cleaning inlet 301 to form cleaning fluid during cleaning. This avoids storing a large amount of cleaning fluid in the cleaning agent storage component 33, which would result in an excessively large cleaning component and further improves the user experience.

[0072] It should be noted that, in practical applications, this application does not impose any restrictions on the specific structural form of the cleaning component, as long as it has a cleaning pipe 31 and a cleaning agent storage component 33, and the two ends of the cleaning pipe form a cleaning inlet 301 and a cleaning outlet 302.

[0073] The following is combined Figure 1 and Figure 2 The cleaning component of this utility model is described in the following two embodiments.

[0074] Example 1:

[0075] like Figure 1 and Figure 3 As shown, the cleaning assembly includes a cleaning pipeline 31 and a cleaning valve 32 and a cleaning agent storage component 33 sequentially disposed on the cleaning pipeline 31. The cleaning agent storage component 33 is located downstream of the cleaning valve 32 and is used to store acidic or alkaline cleaning agents.

[0076] When the cleaning component cleans the reverse osmosis membrane filter element 2, the cleaning valve 32 is opened, and the water in the main inlet 1 enters the cleaning agent storage component 33 through the cleaning inlet 301 and dissolves the cleaning agent stored in the cleaning agent storage component 33 to form a cleaning solution. The cleaning solution is then discharged through the cleaning outlet 302 and transported to the reverse osmosis membrane filter element 2. The reverse osmosis membrane filter element 2 is then soaked in the cleaning solution to remove the dirt on the reverse osmosis membrane filter element 2.

[0077] It should be noted that, in practical applications, those skilled in the art can store cleaning agents in the cleaning agent storage component 33 according to actual application needs. For example, acidic cleaning agents can be stored in the cleaning agent storage component 33, or alkaline cleaning agents can be stored in the cleaning agent storage component 33, etc. Such adjustments and changes to the type of cleaning agent in the cleaning agent storage component 33 do not deviate from the principle and scope of this utility model, and should all be included within the protection scope of this utility model.

[0078] Example 2:

[0079] like Figure 2 and Figure 4 As shown, the cleaning assembly includes at least two parallel cleaning pipes 31, a cleaning valve 32 disposed on each cleaning pipe 31, and a cleaning agent storage component 33. The first ends of the plurality of cleaning pipes 31 converge to form a cleaning inlet 301, and the second ends of the plurality of cleaning pipes 31 converge to form a cleaning outlet 302. The cleaning agent storage component 33 is located downstream of the cleaning valve 32, and the cleaning agent storage component 33 on each cleaning pipe 31 is used to store different types of cleaning agents.

[0080] It should be noted that, in practical applications, this utility model does not limit the specific number of parallel cleaning pipelines 31. For example, two parallel cleaning pipelines 31 can be set, with cleaning valves 32 and cleaning agent storage components 33 respectively on each of the two cleaning pipelines 31. Alternatively, three parallel cleaning pipelines 31 can be set, with cleaning valves 32 and cleaning agent storage components 33 respectively on each of the three cleaning pipelines 31. Or, multiple parallel cleaning pipelines 31 can be set, with cleaning valves 32 and cleaning agent storage components 33 respectively on the multiple main cleaning pipelines, etc. Such adjustments and changes to the specific number of parallel cleaning pipelines 31 do not deviate from the principle and scope of this utility model and should all be included within the protection scope of this utility model.

[0081] The following description uses two parallel cleaning pipelines 31 as an example.

[0082] Specifically, such as Figure 2 and Figure 4As shown, the cleaning assembly includes a first cleaning pipe 311 and a second cleaning pipe 312 arranged in parallel. The first cleaning pipe 311 is provided with a first cleaning valve 321 and a first cleaning agent storage component 331. The second cleaning pipe 312 is provided with a second cleaning valve 322 and a second cleaning agent storage component 332. The first end of the first cleaning pipe 311 and the first end of the second cleaning pipe 312 meet to form a cleaning inlet 301. The second end of the first cleaning pipe 311 and the second end of the second cleaning pipe 312 meet to form a cleaning outlet 302. The first cleaning agent storage component 331 is used to store acidic cleaning agent, and the second cleaning agent storage component 332 is used to store alkaline cleaning agent.

[0083] It should be noted that when cleaning the reverse osmosis membrane filter element 2, an acidic cleaning agent can be used first, followed by an alkaline cleaning agent. Alternatively, an alkaline cleaning agent can be used first, followed by an acidic cleaning agent, and so on. Such flexible adjustments and changes do not deviate from the principles and scope of this utility model and should be included within the protection scope of this utility model.

[0084] The following example illustrates the cleaning process of reverse osmosis membrane filter element 2, which involves first cleaning it with an acidic cleaning agent and then with an alkaline cleaning agent.

[0085] like Figure 2 and Figure 4 As shown, the first cleaning valve 321 is opened while the second cleaning valve 322 remains closed, allowing water from the main inlet channel 1 to enter the first cleaning pipe 311 and form a first cleaning solution (i.e., an acidic solution) in the first cleaning agent storage component 331. This solution is then discharged through the cleaning outlet 302 and transported to the reverse osmosis membrane filter element 2 to soak the reverse osmosis membrane filter element 2 and remove inorganic dirt from it. After cleaning, the liquid in the reverse osmosis membrane filter element 2 is drained and rinsed. Then, the first cleaning valve 321 is closed and the second cleaning valve 322 is opened, allowing water from the main inlet channel 1 to enter the second cleaning pipe 312 and form a second cleaning solution (i.e., an alkaline solution) in the second cleaning agent storage component 332. This solution is then discharged through the cleaning outlet 302 and transported to the reverse osmosis membrane filter element 2 to soak the reverse osmosis membrane filter element 2 and remove organic dirt from it.

[0086] It should be noted that this utility model does not limit the specific type of acidic cleaning agent. For example, the acidic cleaning agent can be at least one of malic acid, citric acid, hydrochloric acid, and phosphoric acid. Of course, the acidic cleaning agent can also be other types of acidic substances, and those skilled in the art can make adjustments according to actual needs.

[0087] Preferably, the acidic cleaning agent is malic acid or citric acid, which not only cleans dirt but also has a good disinfection and antibacterial effect, and can disinfect and inhibit bacteria on the reverse osmosis membrane filter element 2.

[0088] It should also be noted that this utility model does not limit the specific type of alkaline cleaning agent. For example, the alkaline cleaning agent can be set to at least one of dishwashing powder, baking soda, sodium hydroxide, potassium hydroxide, calcium hydroxide, calcium oxide, sodium citrate, tetrasodium ethylenediaminetetraacetate, sodium dodecyl sulfate, sodium disulfite, and sodium bisulfite. Of course, the alkaline cleaning agent can also be other types of alkaline substances, and those skilled in the art can make adjustments according to actual needs.

[0089] It should also be noted that this utility model does not limit the form of the cleaning agent in the first cleaning agent storage component 331 and the second cleaning agent storage component 332. For example, the cleaning agent in both the first cleaning agent storage component 331 and the second cleaning agent storage component 332 can be in solid form, or the cleaning agent in both the first cleaning agent storage component 331 and the second cleaning agent storage component 332 can be in liquid form, or one of the first cleaning agent storage component 331 and the second cleaning agent storage component 332 can be in solid form and the other in liquid form, etc. Such adjustments and changes to the specific form of the cleaning agent stored in the first cleaning agent storage component 331 and the second cleaning agent storage component 332 do not deviate from the principle and scope of this utility model and should be included within the protection scope of this utility model.

[0090] Preferably, the cleaning agents stored in the first cleaning agent storage component 331 and the second cleaning agent storage component 332 are both in solid form.

[0091] More preferably, in order to accelerate the dissolution of the cleaning agent, the cleaning agent is in granular or powder form.

[0092] It should also be noted that, in practical applications, those skilled in the art can install a check valve structure in the detergent storage component 33 to prevent water in the main water inlet 1 from entering the detergent storage component 33 through the cleaning outlet 302. Alternatively, a one-way valve 34 can be installed on the cleaning pipeline 31 to prevent water in the main water inlet 1 from entering the detergent storage component 33 through the cleaning outlet 302. Or, a control valve can be installed on the cleaning pipeline 31 to prevent water in the main water inlet 1 from entering the detergent storage component 33 through the cleaning outlet 302, etc. Such flexible adjustments and changes do not deviate from the principles and scope of this utility model and should all be included within the protection scope of this utility model.

[0093] Preferably, such as Figures 1 to 4As shown, a one-way valve 34 is provided on the cleaning pipeline 31. The one-way valve 34 is located at the downstream end of the cleaning agent storage component 33 and can prevent water in the main water inlet 1 from entering the cleaning agent storage component 33 through the cleaning outlet 302.

[0094] By setting a one-way valve 34, when the water purification equipment is in normal water production mode, it can prevent water in the main inlet pipe 1 from flowing back into the detergent storage component 33, thereby avoiding the detergent from dissolving and entering the reverse osmosis membrane filter element 2 under normal water production mode. At the same time, since the cost of the one-way valve 34 is significantly lower than that of the control valve, compared with setting a control valve on the cleaning pipeline 31, setting a one-way valve 34 to prevent water in the main inlet pipe 1 from entering the detergent storage component 33 through the cleaning outlet 302 can further save the cost of the water purification equipment.

[0095] Specifically, such as Figure 2 and Figure 4 As shown, a first check valve 341 is provided on the first cleaning pipe 311, and a second check valve 342 is provided on the second cleaning pipe 312.

[0096] Preferably, such as Figures 1 to 4 As shown, the water purification equipment of this application also includes a booster pump 12, which is installed on the main water inlet 1 and located upstream of the clean outlet 302.

[0097] By placing the booster pump 12 upstream of the cleaning outlet 302, the cleaning fluid flowing out of the cleaning outlet 302 can be prevented from entering the booster pump 12 and corroding the diaphragm inside the booster pump 12, thereby improving the service life of the booster pump 12 and further enhancing the user experience.

[0098] Preferably, such as Figures 1 to 4 As shown, the water purification equipment of this utility model also includes a pre-filter unit 4. The outlet end of the pre-filter unit 4 is connected to the main water inlet 1, and the cleaning inlet 301 is located at the downstream end of the pre-filter unit 4.

[0099] With this configuration, by placing the cleaning inlet 301 downstream of the pre-filter unit 4, the purified water filtered by the pre-filter unit 4 can enter the cleaning agent storage component 33 through the cleaning inlet 301. The purified water filtered by the pre-filter unit 4 can be used to dissolve the cleaning agent, thereby improving the solubility of the cleaning agent and the cleaning degree of the cleaning solution, thus effectively improving the cleaning effect of the reverse osmosis membrane filter element 2.

[0100] It should be noted that, in practical applications, those skilled in the art can set the pre-filter unit 4 as a pre-filter cartridge, or they can set the pre-filter unit 4 as a composite cartridge including a pre-filter cartridge and a post-filter cartridge, etc. Such adjustments and changes to the specific type of the pre-filter unit 4 do not deviate from the principle and scope of this utility model, and should all be included within the protection scope of this utility model.

[0101] Preferably, the pre-filter unit 4 is a pre-filter cartridge.

[0102] Preferably, such as Figures 1 to 4 As shown, the water purification equipment also includes an inlet valve 11 installed on the main inlet water line 1, with a cleaning inlet 301 located at the upstream end of the inlet valve 11 and a cleaning outlet 302 located at the downstream end of the inlet valve 11.

[0103] With this setup, when the reverse osmosis membrane filter element 2 needs to be cleaned, the water in the main water inlet 1 can be prevented from directly entering the reverse osmosis membrane filter element 2 by controlling the water inlet valve 11, thereby avoiding dilution of the cleaning solution entering the reverse osmosis membrane filter element 2.

[0104] It should be noted that in practical applications, the arrangement is not limited to placing the cleaning inlet 301 upstream of the water inlet valve 11 and the cleaning outlet 302 downstream of the water inlet valve 11. For example, both the cleaning inlet 301 and the cleaning outlet 302 can be placed upstream of the water inlet valve 11, or both can be placed downstream of the water inlet valve 11, and so on. Such adjustments and changes to the relative positions of the cleaning components and the water inlet valve 11 do not deviate from the principles and scope of this utility model and should be included within the protection scope of this utility model. Preferably, the cleaning inlet 301 is placed upstream of the water inlet valve 11, and the cleaning outlet 302 is placed downstream of the water inlet valve 11.

[0105] It should also be noted that, in practical applications, those skilled in the art can place the booster pump 12 upstream of the inlet valve 11, or they can place the booster pump 12 downstream of the inlet valve 11, etc. Such adjustments and changes to the specific positions of the booster pump 12 and the inlet valve 11 do not deviate from the principle and scope of this utility model, and should all be included within the protection scope of this utility model.

[0106] Preferably, such as Figures 1 to 4 As shown, the booster pump 12 is located upstream of the inlet valve 11, and the cleaning inlet 301 is located between the booster pump 12 and the inlet valve 11.

[0107] By placing the booster pump 12 upstream of the inlet valve 11 and placing the cleaning inlet 301 between the booster pump 12 and the inlet valve 11, the cleaning inlet 301 can be located downstream of the booster pump 12. This facilitates the pumping of water from the main inlet channel 1 into the cleaning assembly and then into the reverse osmosis membrane filter element 2 via the booster pump 12, thereby improving cleaning efficiency and cleaning effect.

[0108] It should be noted that, in practical applications, those skilled in the art can configure the water purification equipment as a water purifier, or as an integrated water purifier and drinking water machine, or as any other possible type, etc. Such adjustments and changes to the specific configuration type of the water purification equipment do not deviate from the principles and scope of this utility model and should all be included within the protection scope of this utility model.

[0109] For example, the water purification device is a water purifier.

[0110] The technical solution of this utility model has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, 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 all fall within the protection scope of this utility model.
