DETAILED DESCRIPTION

[0053] In order to make the objectives, technical solutions, and advantages of the embodiments of the present disclosure clearer, the technical solutions in the embodiments of the present disclosure will be described clearly and completely below. Obviously, the described embodiments are some, but not all, of the embodiments of the present disclosure. Based on the embodiments in the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present disclosure.

[0054] A desktop water purifier produces a certain proportion of concentrated water when it runs its waterway system, which is due to the application of RO reverse osmosis technology. This technology is a liquid concentration process in which part of the water, together with impurities and salts therein, is intercepted by a filtering membrane, thereby producing concentrated water.

[0055] In the current design of a desktop water purifier, the concentrated water tank and the raw water tank 72 are usually set separately, which results in a low utilization rate of concentrated water, and thus increases the frequency of replenishing raw water, causing inconvenience to users.

[0056] Referring to FIGS. 1-12, the present disclosure provides a water system, which includes a partition plate 721, a booster pump 75, a raw water tank 72, a pure water tank 73, a water purifier 74, a total dissolved solids meter, and a concentrated water valve. The water purifier 74 is provided with a water inlet end 23, a concentrated water outlet end 24, and a pure water outlet end 25. The partition plate 721 separates the inner bottom surface of the raw water tank 72, so that the raw water tank 72 is divided into a raw water groove 7211 and a concentrated water groove 7212. The input end of the booster pump 75 is connected to the raw water groove 7211 through a pipeline. The output end of the booster pump 75 is connected to the water inlet end 23 through a pipeline. The two ends of the concentrated water valve are connected to the concentrated water groove 7212 and the concentrated water outlet end 24 through pipelines, respectively. The pure water outlet end 25 is connected to the input end of the pure water tank 73 through an outlet pipe. The total dissolved solids meter is arranged on the outlet pipe and is used to detect the liquid flowing through the outlet pipe.

[0057] The present disclosure improves the design of the water system of a desktop water purifier to improve the utilization rate of concentrated water. Specifically, the water system includes a partition plate 721, which divides the raw water tank 72 into two parts: a raw water groove 7211 and a concentrated water groove 7212. The booster pump 75 transports the water in the raw water groove 7211 to the water inlet end 23 of the water purifier 74. The water purifier 74 filters water through the RO reverse osmosis technology to produce pure water and concentrated water. The concentrated water valve connects the concentrated water groove 7212 and the concentrated water outlet end 24 of the water purifier 74, allowing the concentrated water to flow back to the water purifier 74, thereby reducing the direct production of concentrated water. The total dissolved solids meter is used to detect the liquid in the outlet pipe to ensure that the water quality meets the standard. In this way, the system can recycle part of the concentrated water, reduce the consumption of raw water, and reduce the frequency of users replenishing raw water.

[0058] In actual use, the ratio of pure water to concentrated water produced by the water purifier 74 of the present disclosure is approximately three to one.

[0059] Before use, the concentrated water groove 7212 and the raw water groove 7211 are both filled with raw water. During use, concentrated water is continuously produced and flows back to the concentrated water groove 7212, causing the water in the concentrated water groove 7212 to overflow into the raw water groove 7211, so as to realize the recycling of concentrated water.

[0060] The total dissolved solids meter can also be referred to as a TDS meter in the art.

[0061] After the TDS meter is preset, in order to avoid overloading the filter element 2 of the water purifier 74, the user needs to empty the concentrated water in the concentrated water groove 7212 and refill it with raw water.

[0062] In order to facilitate the user to extract the raw water, in an embodiment, the water system further comprises a kettle and a diaphragm pump 79, the input end of the diaphragm pump 79 is communicated to the water outlet end of the pure water tank 73 through a pipeline, and the output end of the diaphragm pump 79 is communicated to the kettle through a pipeline. The structure is simple and convenient to set.

[0063] In order to facilitate the user to heat the pure water, in an embodiment, the water system further comprises a heating device 95, the output end of the kettle is connected to the input end of the heating device 95 through a pipeline, and the heating device 95 is used for heating water. The water system is additionally provided with the heating device 95, which is connected to the output port of the kettle through a pipeline, and its main function is to heat the water flowing through it so that the user can obtain heated water.

[0064] In order to prevent the user from being scalded by high-temperature steam and to stabilize the water flow rate and water shape of the water outlet of the water purifier 74, in an embodiment, the water system further comprises a water vapor separation box 76, the input end of the water vapor separation box 76 is connected to the output end of the heating device 95 through a pipeline. In actual application, the water vapor separation box 76 is installed downstream of the heating device 95. Its main function is to separate high-temperature steam and water and distribute them evenly to prevent the user from being scalded by high-temperature steam. In addition, it can also ensure that the water outlet speed and water flow shape of the water purifier 74 remain stable.

[0065] In order to avoid the water in the pure water tank from flowing back to the water purifier 74, in an embodiment, a check valve 77 is arranged on the water outlet pipe, and the check valve 77 is used to make the water flowing out of the pure water outlet end 25 unidirectionally flow to the pure water tank. The structure is simple and convenient to set.

[0066] The water purifier 74 is used for purifying raw water, and in an embodiment, the water purifier 74 comprises a filter element 2 and a base 1, the filter element 2 is detachably arranged on the base 1, the water inlet end 23, the concentrated water outlet end 24 and the pure water outlet end 25 are arranged on the base 1, the tap water inlet 231, the drinking water outlet 251 and the concentrated water outlet 241 are arranged on the filter element 2, the water inlet end 23 is inserted into the tap water inlet 231, the concentrated water outlet end 24 is inserted into the concentrated water outlet 241, and the pure water outlet end 25 is inserted into the drinking water outlet 251. The filter element 2 is detachably arranged on the base 1, and the user can replace the filter element 2 when the filter element 2 reaches the service life.

[0067] The current filter cartridge 2 and the connection of the water purifier mainly depends on the threaded connection. Therefore, when replacing the filter cartridge 2, it is usually necessary to screw the filter cartridge 2 to separate it from the water purifier. However, the threaded connection method can generate vibration when the water purifier is in operation, which can exert pressure on the threaded connection point. Over time, this pressure can cause local plastic deformation on the threaded contact surface. The gradual accumulation of this strain increases the preload, eventually making it more difficult to disassemble the filter cartridge 2 after its service life.

[0068] To this end, in one embodiment, the water purifier 74 further comprises a handle 3, a first limiting block 4 and a hook assembly, the base 1 is provided with a mounting hole 11, the filter cartridge 2 is inserted in the mounting hole 11, the filter cartridge 2 and the mounting hole 11 are relatively slidable, the first limiting block 4 is fixed on the handle 3, and the hook assembly is arranged on the base 1; the hook assembly is used for limiting and fixing the first limiting block 4 to limit the filter cartridge 2 in the mounting hole 11, the handle 3 is connected to the filter cartridge 2 through a rotating shaft 33, the handle 3 and the filter cartridge 2 are relatively rotatable about the axis of the rotating shaft 33, so that the first limiting block 4 is disengaged from the limitation of the hook assembly or is limited by the hook assembly.

[0069] By adopting a non-threaded connection method, the problem of local plastic deformation of the threaded contact surface caused by vibration is successfully avoided, so that the filter cartridge 2 can be smoothly slid. The user only needs to rotate the handle 3 to easily fix or release the filter cartridge 2 without the need for screwing operation, greatly simplifying the locking and unlocking process. In practical application, the filter cartridge 2 can be directly installed on the filter cartridge 2, thereby simplifying the steps of replacing the filter cartridge 2. In addition, the design of the hook assembly and the first limiting block 4 ensures the stability of the filter cartridge 2 during installation and disassembly, effectively preventing the loosening problem caused by vibration.

[0070] During installation or disassembly of the filter cartridge 2, the filter cartridge 2 and the mounting hole 11 are connected in a relatively slidable manner, of course, the filter cartridge 2 can be withdrawn from the mounting hole 11 or inserted into the mounting hole 11 from outside the mounting hole 11. If the initial state is that the filter cartridge 2 is inserted into the bottom of the mounting hole 11, the first limiting block 4 on the handle 3 is limited by the hook assembly to limit the filter cartridge 2 from sliding out of the mounting hole 11. The filter cartridge 2 is usually installed on the filter cartridge 2, when the user needs to maintain the filter cartridge 2, the filter cartridge 2 needs to be withdrawn from the mounting hole 11 together with the filter cartridge 2. At this time, the user can rotate the handle 3 about the axis of the rotating shaft 33, so that the first limiting block 4 fixed on the handle 3 rotates with the handle 3 about the axis of the rotating shaft 33. Since there is a certain distance between the first limiting block 4 and the axis of the rotating shaft 33, those skilled in the art can adjust the distance between the axis of the rotating shaft 33 and the first limiting block 4 during design, so that when the user rotates the handle 3, the first limiting block 4 can be out of the range of the limitation of the hook assembly, so that the user can directly pull the handle 3 to pull out the filter cartridge 2 from the mounting hole 11.

[0071] When the filter core 2 is inserted into the bottom of the installation hole 11, the first limiting block 4 on the handle 3 can be limited by the pull hook assembly. If the pull hook assembly cannot move, this will cause the process of inserting the filter core 2 into the bottom of the installation hole 11 to require manual rotation of the handle 3, so that the first limiting block 4 on the handle 3 avoids the pull hook assembly, so as to avoid interference between the pull hook assembly and the first limiting block 4 during the insertion of the filter core 2 into the installation hole 11. After the filter core 2 is completely inserted into the bottom of the installation hole 11, the handle 3 is manually rotated again, so that the first limiting block 4 on the handle 3 swings into the area limited by the pull hook assembly, thereby preventing the filter core 2 from accidentally exiting the installation hole 11.

[0072] Although this design can achieve a non-threaded connection, the filter core 2 can easily enter or exit the installation hole 11 by adjusting the handle 3. However, this method still has room for improvement, for example, the first limiting block 4 and the pull hook assembly still need to be manually avoided during the process of inserting the filter core 2 into the bottom of the installation hole 11.

[0073] Therefore, in an embodiment, the pull hook assembly includes a first connecting shaft 51, a tension spring 52, a swing arm 53, and a limiting hook 54. The first connecting shaft 51 is fixed to the base 1. The swing arm 53 has a first shaft hole, and the first connecting shaft 51 is inserted into the first shaft hole. The first shaft hole and the first connecting shaft 51 can rotate relative to each other. The limiting hook 54 is fixed to the swing arm 53, and a limiting space is provided between the limiting hook 54 and the first connecting shaft 51. The limiting space is used to hook the first limiting block 4 to limit the first limiting block 4. One end of the tension spring 52 is connected to the swing arm 53, and the other end of the tension spring 52 is connected to the base 1.

[0074] The first connecting shaft 51 is fixed to the base 1, and the swing arm 53 is provided with a first shaft hole. The first connecting shaft 51 and the first shaft hole are connected by the shaft hole, allowing the swing arm 53 and the first connecting shaft 51 to rotate relative to each other. Assuming that the depth direction of the installation hole 11 is vertical, i.e., along the up-down direction, the length direction of the first connecting shaft 51 is horizontal, i.e., along the front-back direction. In the initial natural state of the swing arm 53, the length direction is also vertical, i.e., extending along the up-down direction, and the limiting hook 54 is located above the first shaft hole.

[0075] When the user needs to insert the filter element 2 into the bottom of the installation hole 11, the filter element 2 can be inserted into the installation hole 11. If the first limiting block 4 on the handle 3 has not been adjusted to the position avoiding the limiting hook 54, when the first limiting block 4 contacts the limiting hook 54, the external force applied by the user will push the filter element 2 to move towards the bottom of the installation hole 11, forcing the limiting block and the swing arm 53 connected thereto to rotate around the first connecting shaft 51. In the process of rotating the limiting block around the first connecting shaft 51, it overcomes the tension of the tension spring 52, causing the tension spring 52 to be elongated. Once the filter element 2 is completely inserted into the bottom of the installation hole 11, the swing arm 53 will return to the initial position under the elastic restoring force of the tension spring 52, and at the same time the elastic restoring force of the tension spring 52 will also push the first limiting block 4 to move to the limiting range of the limiting hook 54.

[0076] After a long period of use, the length of the tension spring 52 in the natural state may change, which may cause the position of the swing arm 53 in the natural state of the natural tension spring 52 to be different, which will affect the position of the limiting hook 54 for limiting. It may cause the limiting hook 54 to fail to limit the first limiting block 4.

[0077] Therefore, in an embodiment, the hook assembly further comprises a second limiting block 55, the second limiting block 55 is fixed on the base 1, the tension spring 52 and the second limiting block 55 are located on the same side of the swing arm 53, and the second limiting block 55 is used for limiting the swing arm 53 to limit the stroke of the swing arm 53. In this way, the tension spring 52 can be designed to always maintain elastic potential energy, so that the tension spring 52 always generates a pulling force on the swing arm 53, so that in the natural state, the swing arm 53 is attached to the second limiting block 55, thereby ensuring that the limiting hook 54 maintains a fixed position in the natural state.

[0078] In the process of the user inserting the filter element 2 into the bottom of the installation hole 11, when the first limiting block 4 and the limiting hook 54 are in contact, it is possible that due to the angle of contact between the first limiting block 4 and the limiting hook 54, the force acting on the limiting hook 54 fails to generate a component force that makes the limiting hook 54 rotate around the first connecting shaft 51, thereby causing the first limiting block 4 and the limiting hook 54 to be stuck. Therefore, in an embodiment, the face of the limiting hook 54 facing away from the bottom of the installation hole 11 is referred to as the top face of the limiting hook 54, and a first guide inclined surface 541 is arranged at the side edge of the top face of the limiting hook 54. This structure is simple and convenient to set. By arranging the first guide inclined surface 541 on the limiting hook 54, when the first guide inclined surface 541 and the first limiting block 4 are in contact, a force that makes the limiting hook 54 rotate can be generated through the first guide inclined surface 541, thereby avoiding the phenomenon of being stuck.

[0079] In order to further make the first limiting block 4 and the first guide inclined surface 541 contact, the two can smoothly relative motion, in an embodiment, the first limiting block 4 is provided with a second guide chamfer 41, the face of the first limiting block 4 towards the bottom of the mounting hole 11 is called a guide surface, and the second guide chamfer 41 is arranged on the edge of the guide surface close to the limiting hook 54. In use, the second guide chamfer 41 is in contact with the first guide inclined surface 541 to make the limiting hook 54 rotate around the first connecting shaft 51.

[0080] The swing arm 53 is sleeved on the first connecting shaft 51 through the shaft hole, if the swing arm 53 is not limited in the axial direction of the first connecting shaft 51, the swing arm 53 will have the risk of being separated from the first connecting shaft 51. However, if the swing arm 53 is limited, it will not be able to be separated from the first connecting shaft 51, and the difficulty of maintenance will be increased. Thus, in an embodiment, the pull hook assembly further comprises a gland 56, the gland 56 and the base 1 are detachably connected, and the gland 56 is used for limiting the swing arm 53 in the direction of the first connecting shaft 51. Through the detachable connection between the gland 56 and the base 1, the swing arm 53 is limited in the axial direction of the first connecting shaft 51 by the gland 56, and the swing arm 53 is ensured on the first connecting shaft 51.

[0081] Optionally, the gland 56 and the base 1 are connected through screws. In addition, the gland 56 and the base 1 can also be connected and fixed through elastic buckles. Of course, these two methods can realize the detachable connection between the gland 56 and the base 1.

[0082] The positions of the water inlet end 23, the concentrated water outlet end 24 and the purified water outlet end 25 on the water purifier 74 are generally fixed relative to the filter element 2. For example, in some embodiments, the tap water inlet 231, the purified water outlet 251 and the concentrated water outlet 241 correspond to the water inlet end 23, the purified water outlet end 25 and the concentrated water outlet end 24 respectively. Therefore, after the filter element 2 is inserted into the mounting hole 11, the relative angle between the filter element 2 and the base 1 needs to be consistent. To this end, in an embodiment, a first protruding block 21 is arranged on the filter element 2, and a guide groove 12 is arranged on the base 1. The guide groove 12 is arranged on the inner wall of the mounting hole 11, and the first protruding block 21 is inserted into the guide groove 12, and the first protruding block and the guide groove 12 are in sliding fit. This structure is simple and convenient to set. When the filter element 2 is inserted into the mounting hole 11, the first protruding block 21 on the filter element 2 needs to be inserted into the guide groove 12, for example, the guide groove 12 limits and guides the first protruding block 21, so as to ensure that the relative angle between the filter element 2 and the base 1 is consistent when the filter element 2 is inserted into the mounting hole 11 each time. In addition, the cooperation of the first protruding block 21 and the guide groove 12 can effectively limit the relative rotation between the filter element 2 and the mounting hole 11. In particular, when the part of the filter element 2 inserted into the mounting hole 11 is arranged as a rotary body, for example, the part of the filter element 2 inserted into the mounting hole 11 is arranged as a cylinder, and so on.

[0083] The guide groove 12 is used to guide and limit the first protruding block 21. In order to facilitate the operator to conveniently insert the first protruding block 21 into the guide groove 12, in an embodiment, the length of the guide groove 12 extends along the depth direction of the mounting hole 11, and the length of the guide groove 12 gradually decreases along the depth of the mounting hole 11.

[0084] Since the length of the guide groove 12 gradually decreases along the depth of the mounting hole 11, the width of the first protruding block 21 is relatively large when it is inserted into the entrance of the guide groove 12, which can effectively play a guiding role.

[0085] The handle 3 and the filter element 2 are connected through the rotating shaft 33, so that the handle 3 and the filter element 2 can rotate relative to each other. In an embodiment, the rotating shaft 33 is fixed on the handle 3, a first installation space is arranged in the filter element 2, a second shaft hole is arranged on the filter element 2 and communicates with the first installation space, and the rotating shaft 33 extends into the first installation space through the second shaft hole. This structure is simple and convenient to set. The rotating shaft 33 is inserted into the first installation space, which can ensure the stable connection between the rotating shaft 33 and the filter element 2.

[0086] Further, two second shaft holes are arranged, and the two ends of the handle 3 are respectively and correspondingly inserted into the second shaft holes through the rotating shaft 33.

[0087] In one of the above-mentioned embodiments, the limiting hook 54 can limit the first limiting block 4 by rotating the handle 3, so that the filter element 2 is limited in the mounting hole 11. However, during use, once the handle 3 is rotated, the filter element 2 may be immediately unlocked, thereby causing the filter element 2 to accidentally slide out of the mounting hole 11. In one embodiment, the waterway system further comprises a locking block 61, a spring 62 and a button 63, the handle 3 is provided with a clamping groove 31, one end of the spring 62 is connected with the base 1, the other end of the spring 62 is connected with the button 63, the button 63 is connected with the base 1 in a relatively sliding manner, and the locking block 61 is fixed on the button 63 and inserted into the clamping groove 31.

[0088] When the first limiting block 4 is in the state of being limited by the hook assembly, the filter element 2 will be limited in the mounting hole 11. The handle 3 is provided with a clamping groove 31 for receiving the locking block 61. When the locking block 61 is inserted into the clamping groove 31, the handle 3 is locked and cannot be rotated. By arranging the locking block 61, the spring 62 and the button 63, the handle 3 is locked to prevent the handle 3 from rotating, so that the handle 3 remains in a state that the first limiting block 4 is within the limiting range of the hook assembly. In addition, the locking block 61 is fixed on the button 63, one end of the spring 62 is connected with the base 1, the other end is connected with the button 63, and the button 63 can slide on the base 1. When it is necessary to unlock, the user can press the button 63 to overcome the elastic force of the spring 62, so that the locking block 61 moves out of the clamping groove 31, thereby allowing the handle 3 to rotate. When the button 63 is released, the spring 62 pushes the button 63 and the locking block 61 back to the original position, thereby relocking the handle 3.

[0089] In this way, the safety is effectively improved. By cooperating the locking block 61 and the clamping groove 31, the accidental rotation of the handle 3 in the non-operation state is effectively prevented, thereby avoiding the risk of accidental sliding of the filter element 2 and improving the safety during use. Moreover, the operation is convenient. When it is necessary to disassemble and assemble, the user only needs to press the button 63 to unlock the handle 3, which is simple and convenient. Meanwhile, the structure is stable. The use of the spring 62 ensures that the button 63 and the locking block 61 can be stably maintained in the locked position in the non-operation state, thereby ensuring the stability of the structure.

[0090] When it is assumed that the depth direction of the mounting hole 11 extends in the up-down direction, and the first connecting shaft 51 extends in the front-rear direction, the extension direction of the spring 62 can be in the up-down direction, the front-rear direction or the left-right direction, etc. Those skilled in the art can adjust the installation position according to the actual situation.

[0091] According to the present embodiment, the spring 62 is installed in a direction that extends and retracts in the left-right direction to save space and make the structure compact. In one embodiment, the inner wall of the mounting hole 11 is provided with a recessed portion 111, forming a first space at the recessed portion 111. One end of the spring 62 is connected to the inner bottom surface of the recessed portion 111, and the other end of the spring 62 is connected to the lock block 61. A barrier is provided at the opening of the recessed portion 111, dividing the opening into a first guide hole 1111 and a second guide hole 1112 that communicate with the first space. The lock block 61 is arranged at the first guide hole 1111 and can slide relative to the first guide hole 1111. The button 63 passes through the second guide hole 1112 and can slide relative to the second guide hole 1112. The filter element 2 is provided with a first sunken platform 20 on the surface facing away from the mounting hole 11, and the first sunken platform 20 extends to one side surface of the filter element 2. The side wall of the button 63 faces the side wall of the first sunken platform 20.

[0092] In the present embodiment, the inner wall of the mounting hole 11 is provided with a recessed portion 111, forming a first space. One end of the spring 62 is fixed to the inner bottom surface of the recessed portion 111, and the other end is connected to the lock block 61. A barrier is provided at the opening of the recessed portion 111, dividing the opening into a first guide hole 1111 and a second guide hole 1112. The lock block 61 is arranged at the first guide hole 1111 and can slide relative to the first guide hole 1111. The button 63 passes through the second guide hole 1112 and can slide relative to the second guide hole 1112. The filter element 2 is provided with a first sunken platform 20 on the surface facing away from the mounting hole 11, and the first sunken platform 20 extends to one side surface of the filter element 2. The side wall of the button 63 faces the side wall of the first sunken platform 20.

[0093] The spring 62 provides a spring force, allowing the lock block 61 to maintain contact with the inner wall of the recessed portion 111 or move under certain conditions. When the lock block 61 is located in the first guide hole 1111, it can cooperate with a specific part of the filter element 2 to achieve locking. By operating the button 63, the lock block 61 can be pushed to move, thereby achieving unlocking.

[0094] Since the lock block 61 and the button 63 slide relative to the first guide hole 1111 and the second guide hole 1112, respectively, precise control and positioning can be achieved, ensuring the accuracy and reliability of the locking and unlocking actions. The design of the first sunken platform 20 allows the user's hand to press the button 63 through the sunken platform, making the structure more compact and saving space while ensuring the convenience of operation.

[0095] If the first sink 20 is directly opened on the filter core 2, and the depth of the first sink 20 can meet the user's pressing the button 63 near the inside surface of the mounting hole 11, it needs the first sink 20 to be set with a larger depth, which will increase the height of the filter core 2 invisibly. Therefore, in an embodiment, the handle 3 is set in a C shape, and the two ends of the C-shaped handle 3 are connected to the filter core 2 through the rotating shaft 33 respectively, and the handle 3 is provided with a second recess at the middle of the surface facing the bottom of the mounting hole 11, and the button 63 extends into the space of the second recess. Through the setting of the second recess, the middle part of the handle 3 is set to be thinner, so as to reduce the shielding of the handle 3 to the button 63, so that the designer can correspondingly reduce the depth of the sink when designing. In addition, through the setting of the second recess, it meets the ergonomic design, which can facilitate the user to hold the handle 3 in the second recess.

[0096] When the filter core 2 needs to be connected with other external parts through plug-in and other ways, the user often needs to exert a larger force to pull out the filter core 2 in the mounting hole 11, so that the operation becomes more difficult. In order to facilitate the user to pull out the filter core 2 from the mounting hole 11, in an embodiment, the handle 3 is provided with a second protruding block 32, and when the first limiting block 4 is separated from the hook assembly by rotating the handle 3, the second protruding block 32 abuts against the base 1 to drive the filter core 2 to move away from the bottom of the mounting hole 11. When it is needed to pull out the filter core 2 from the mounting hole 11, the user can rotate the handle 3, so that the second protruding block 32 on the handle 3 contacts the base 1. By rotating the handle 3, the second protruding part exerts pressure on the base 1, forming a labor-saving lever mechanism, and then pushing the filter core 2 to move away from the bottom of the mounting hole 11. This design reduces the force required by the user to pull out the filter core 2, making the disassembly process more convenient.

[0097] The filter core 2 is used for filtering raw water. In an embodiment, the filter core 2 includes a shell, a pre-filter material 8 and a reverse osmosis composite filter material 9, the shell is provided with a second installation space, the pre-filter material 8 and the reverse osmosis composite filter material 9 are arranged in the second installation space, a tap water inlet 231, a drinking water outlet 251 and a concentrated water outlet 241 are arranged on the shell, and the tap water inlet 231, the drinking water outlet 251 and the concentrated water outlet 241 are communicated to the second installation space; under the driving of the booster pump 75, the raw water of the raw water tank 72 enters the second installation space from the tap water inlet 231 through the water inlet end 23, and the raw water entering the second installation space is first filtered by the pre-filter material 8 to obtain primary filtered water, and the primary filtered water is subjected to reverse osmosis of the reverse osmosis composite filter material 9 to be divided into concentrated water flowing out of the concentrated water outlet 241 and pure water flowing out of the drinking water outlet 251.

[0098] The raw water is initially filtered by the pre-filter material 8, which effectively removes large particulate impurities, suspended solids, and some harmful substances from the water, providing cleaner water for the reverse osmosis composite filter 9. The reverse osmosis composite filter 9 utilizes reverse osmosis technology to effectively remove dissolved salts, heavy metals, bacteria, viruses, and other small particles from the water, ensuring that the output of pure water meets drinking water standards. The combination of pre-filtering and reverse osmosis composite filter 9 achieves multiple filtration of raw water, improving filtration efficiency and water quality. The second mounting space on the shell concentrates the pre-filter material 8 and the reverse osmosis composite filter 9, making the filter core 2 compact in structure, easy to install and maintain. In an embodiment, the first mounting space is also provided in the second mounting space, and the first mounting space and the second mounting space are independent of each other. Under the drive of the booster pump 75, the raw water in the raw water tank 72 can smoothly pass through the filter core 2, ensuring the continuity and stability of the filtration process. After the reverse osmosis effect, the raw water is divided into concentrated water and pure water, the concentrated water is discharged through the concentrated water outlet 241, and the pure water is used by the user through the drinking water outlet 251, realizing effective separation and utilization of water.

[0099] The pre-filter material 8 can be used to preliminarily filter the raw water, effectively removing large particulate impurities, suspended solids, and some harmful substances from the water. In an embodiment, the pre-filter material 8 includes, in the direction of water flow, a first non-woven fabric 81, a scale inhibitor layer 82, a first carbon fiber layer 83, activated carbon 84, and a PP melt-blown layer 85. The pre-filter material 8 uses a multi-layer filtration technology. First, the first non-woven fabric 81 effectively intercepts silt, suspended solids, and large particulate impurities, ensuring preliminary purification of the water quality. Then, the scale inhibitor layer 82 plays a role in dispersing insoluble inorganic salts, preventing them from precipitating and scaling, thereby avoiding clogging of subsequent filter materials. The third layer uses a first carbon fiber to further remove odors, pigments, residual chlorine, and organic matter from the water, improving water quality taste. The activated carbon 84 layer deeply purifies, removing residual chlorine and organic matter from the water, ensuring the purity and safety of drinking water. In addition, the PP melt-blown layer 85 intercepts carbon powder from the front end, preventing it from affecting the performance of subsequent filter materials, ensuring efficient operation of the entire filtration system.

[0100] The reverse osmosis composite filter 9 utilizes reverse osmosis technology to effectively remove dissolved salts, heavy metals, bacteria, viruses and other small particles in water, ensuring that the output of pure water meets the drinking water standards. In one embodiment, the reverse osmosis composite filter 9 includes, in order from the raw water to the raw water, a reverse osmosis membrane 91, a first filter layer 92, a second carbon fiber layer 93, and a second filter layer 94. First, the first filter layer 92 serves to isolate the carbon fiber from the RO membrane to prevent the RO membrane from being scratched or clogged. Next, the carbon fiber layer, which is located behind the first layer, deeply removes residual chlorine and organic matter in the water, while increasing trace elements in the output water, thereby significantly improving the taste of the drinking water. Finally, the second filter layer 94 ensures that the particles of the carbon fiber layer do not flow into the drinking water outlet 251, avoiding an increase in the turbidity of the output water and ensuring clear water quality.

[0101] To further compact the installation structure and improve space utilization, in an embodiment, the filter cartridge 2 further comprises an upper end cover 26 and a lower end cover 27, the upper end cover 26 and the lower end cover 27 are respectively arranged in the second installation space, the pre-filter material 8 is arranged in a ring shape, the reverse osmosis composite filter material 9 is arranged in a ring shape, the reverse osmosis composite filter material 9 is arranged inside the ring of the ring-shaped pre-filter material 8, the upper end cover 26 covers one end of the ring-shaped pre-filter material 8 and the ring-shaped reverse osmosis composite filter material 9, and the lower end cover 27 covers the other end of the ring-shaped pre-filter material 8 and the ring-shaped reverse osmosis composite filter material 9, the pre-filter material 8 divides the second installation space, a first cavity in a ring shape is formed between the pre-filter material 8, the upper end cover 26, the lower end cover 27 and the inner wall of the shell, a second cavity is formed between the pre-filter material 8, the reverse osmosis composite filter material 9, the upper end cover 26 and the lower end cover 27, a third cavity is formed between the inner side of the ring-shaped composite filter material and the upper end cover 26 and the lower end cover 27, the tap water inlet 231 is connected to the first cavity, the concentrated water outlet 241 is connected to the second cavity, and the drinking water outlet 251 is connected to the third cavity. The structure is compact and has high space utilization. In the second installation space, the arrangement of the upper end cover 26 and the lower end cover 27 cooperates with the ring-shaped pre-filter material 8 and the reverse osmosis composite filter material 9 to create a compact layout. The ring-shaped design not only makes full use of the limited space, but also optimizes the arrangement of the upper end cover 26 and the lower end cover 27 to further reduce space waste. In addition, the pre-filter material 8 in the second installation space plays a partitioning role, which helps to effectively isolate different types of filter materials and ensure their independent operation, thereby improving the filtering efficiency. The multi-cavity design realizes multi-stage filtration through the different cavities formed by the pre-filter material 8, the upper end cover 26, the lower end cover 27 and the inner wall of the shell, and the arrangement of the third cavity ensures the independence of the reverse osmosis process. The optimized design of the fluid channel makes the tap water inlet, the concentrated water outlet and the drinking water outlet respectively connected to different cavities, ensuring reasonable distribution of water flow and efficient filtration, while avoiding cross contamination. The reasonable cavity design and filter material layout ensure that the water flow undergoes sufficient pre-filtering and reverse osmosis treatment, thereby improving the overall filtering efficiency and water quality. In addition, the arrangement of the upper end cover and the lower end cover makes the assembly of the filter cartridge convenient, and the filter cartridge can be easily assembled during production.

[0102] To stabilize the water purification load of the water purifier, in an embodiment, the partition plate divides the bottom area of the raw water tank, so that the volume ratio of the raw water tank and the concentrated water tank is four to one. Specifically, the ratio of pure water to concentrated water produced by the waterway system is 3:1. If the raw water tank is completely divided into two parts by the partition plate, one part serves as the raw water tank and occupies 75% of the volume of the raw water tank, and the other part serves as the concentrated water tank and occupies 25% of the volume of the raw water tank. The partition plate should be installed at about 1 / 4 of the bottom area of the raw water tank, and its height should match the designed maximum liquid level, so that the filter cartridge can always bear a stable pollution load, i.e. the concentration of the incoming water remains unchanged.
