[0002] Desktop water purifiers are usually equipped with a filtration system that can effectively remove impurities, residual chlorine, heavy metals, bacteria, viruses and other harmful components in tap water to ensure the cleanliness and safety of drinking water.

[0003] The water system of a tabletop water purifier produces a certain amount of concentrated water during operation. This is due to the RO reverse osmosis technology it uses. This technology is a liquid concentration process in which some water, along with impurities and salts, is retained by the filter membrane, resulting in concentrated water.

[0004] In the current design of desktop water purifiers, the concentrated water tank and the raw water tank are usually set separately, resulting in low utilization of the concentrated water, which in turn increases the frequency of replenishing raw water and brings inconvenience to users.

DETAILED DESCRIPTION

[0046] To more clearly illustrate the technical solutions in the embodiments of the present disclosure, the above briefly describes the drawings required for use in describing the embodiments. Obviously, the drawings described are only part of the embodiments of the present disclosure, not all of them. Those skilled in the art can also derive other design solutions and drawings based on these drawings without inventive effort.

[0047] The following will clearly and completely describe the concept, specific structure and technical effects of the present disclosure in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments of the present disclosure, other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present disclosure. In addition, all the connection / connection relationships mentioned in the text do not refer solely to the direct connection of components, but refer to the fact that a better connection structure can be formed by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the present disclosure can be combined interactively without conflicting with each other.

[0048] Tabletop water purifiers produce a certain amount of concentrated water when operating their water system. This is due to the RO reverse osmosis technology they use. This technology is a liquid concentration process in which a portion of the water, along with impurities and salts, is retained by the filter membrane, resulting in concentrated water.

[0049] In the current design of desktop water purifiers, the concentrated water tank and the raw water tank 72 are usually set up independently, which results in a low utilization rate of the concentrated water, thereby increasing the frequency of replenishing the raw water, causing inconvenience to the user.

[0050] Please refer to Figures 1 to 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 23, a concentrated water outlet 24 and a purified water outlet 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 tank 7211 and a concentrated water tank 7212. The input end of the booster pump 75 is connected to the raw water tank 7211 through a pipeline, and the output end of the booster pump 75 is connected to the water inlet 23 through a pipeline. The two ends of the concentrated water valve are respectively connected to the concentrated water tank 7212 and the concentrated water outlet 24 through pipelines. The purified water outlet 25 is connected to the input end of the pure water tank 73 through an outlet pipe. The total dissolved solids meter is located on the outlet pipe. The total dissolved solids meter is used to detect the liquid flowing through the outlet pipe.

[0051] The present disclosure improves the utilization rate of concentrated water by improving the water system design of a desktop water purifier. Specifically, the water system includes a partition plate 721, which divides the raw water tank 72 into two parts: a raw water tank 7211 and a concentrated water tank 7212. The booster pump 75 transports the water in the raw water tank 7211 to the water inlet 23 of the water purifier 74. The water purifier 74 filters water through RO reverse osmosis technology to produce clean water and concentrated water. The concentrated water valve connects the concentrated water tank 7212 and the concentrated water outlet 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 water outlet pipe to ensure that the water quality meets the standards. 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.

[0052] 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.

[0053] Before use, both the concentrated water tank 7212 and the raw water tank 7211 are filled with raw water. During use, concentrated water is continuously produced and flows back into the concentrated water tank 7212, causing the water in the concentrated water tank 7212 to overflow into the raw water tank 7211, thereby realizing the reuse of the concentrated water.

[0054] A total dissolved solids meter is also known as a TDS meter in the art.

[0055] When the TDS meter reaches the preset value, 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 tank 7212 and fill it with raw water.

[0056] To facilitate the extraction of raw water by the user, in one embodiment, the water system further includes a kettle and a diaphragm pump 79. The input end of the diaphragm pump 79 is connected to the water outlet end of the pure water tank 73 via a pipe, and the output end of the diaphragm pump 79 is connected to the kettle via a pipe. This structure is simple and easy to set up.

[0057] To facilitate the user to heat the pure water, in one embodiment, the water system further includes a heating device 95. The output end of the kettle is connected to the input end of the heating device 95 via a pipe. The heating device 95 is used to heat the water. The water system is equipped with a heating device 95, which is connected to the output port of the kettle via a pipe. Its main function is to heat the water flowing through it so that the user can obtain heated water.

[0058] To prevent users from being burned by high-temperature steam and to maintain a stable flow rate and shape of the water flowing out of the water purifier 74, in one embodiment, the water system also includes 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 via a pipe. In practice, the water vapor separation box 76 is installed downstream of the heating device 95. Its primary function is to separate the high-temperature steam and water, and evenly distribute them to prevent users from being burned by the high-temperature steam. It also ensures a stable water flow rate and shape from the water purifier 74.

[0059] In order to prevent the water in the clean water tank from flowing back into the water purifier 74, in one embodiment, a check valve 77 is provided on the water outlet pipe. The check valve 77 is used to make the water flowing out of the clean water outlet 25 flow in one direction to the clean water tank. This structure is simple and easy to set up.

[0060] The water purifier 74 is used to purify raw water. In one embodiment, the water purifier 74 includes a filter cartridge 2 and a base 1. The filter cartridge 2 is detachably mounted on the base 1. The water inlet 23, concentrated water outlet 24, and purified water outlet 25 are respectively mounted on the base 1. The filter cartridge 2 is provided with a tap water inlet 231, a drinking water outlet 251, and a concentrated water outlet 241. The water inlet 23 is inserted into the tap water inlet 231, the concentrated water outlet 24 is inserted into the concentrated water outlet 241, and the purified water outlet 25 is inserted into the drinking water outlet 251. The filter cartridge 2 is detachably mounted on the base 1 and can be replaced by the user after reaching the end of its service life.

[0061] Currently, the connection between the filter cartridge 2 and the water purifier primarily relies on a threaded fit. Therefore, when replacing the filter cartridge 2, it is typically necessary to twist the filter cartridge 2 to separate it from the water purifier. However, this threaded connection generates vibrations during the operation of the water purifier, which exerts pressure on the threaded connection points. Over time, this pressure can cause localized plastic deformation on the threaded contact surface. The gradual accumulation of this strain increases the preload force, ultimately making removal of the filter cartridge 2 more difficult after it reaches the end of its service life.

[0062] To this end, in one embodiment, the water purifier 74 also includes a handle 3, a first limit block 4 and a hook assembly. A mounting hole 11 is provided on the base 1, and the filter element 2 is inserted into the mounting hole 11. The filter element 2 and the mounting hole 11 can slide relative to each other. The first limit block 4 is fixed on the handle 3, and the hook assembly is arranged on the base 1; the hook assembly is used to limit and fix the first limit block 4 to limit the filter element 2 in the mounting hole 11. The handle 3 is connected to the filter element 2 through a rotating shaft 33. The handle 3 and the filter element 2 can rotate relative to the axis of the rotating shaft 33, so that the first limit block 4 is disengaged from the limit of the hook assembly or is limited by the hook assembly.

[0063] By adopting a non-threaded connection method, the problem of local plastic deformation of the threaded contact surface caused by vibration is successfully avoided, allowing the filter element 2 to slide smoothly. The user can easily fix or release the filter element 2 by simply turning the handle 3, without the need for screwing, greatly simplifying the locking and unlocking process. In actual application, the filter element 2 can be directly installed on the filter element 2, thus simplifying the steps of replacing the filter element 2. In addition, the design of the hook assembly and the first limit block 4 ensure the stability of the filter element 2 during installation and removal, effectively preventing loosening caused by vibration.

[0064] When installing or removing the filter element 2, the filter element 2 and the mounting hole 11 are connected in a relatively sliding manner. Of course, the filter element 2 can be removed from the mounting hole 11 or inserted into the mounting hole 11 from outside the mounting hole 11. If the filter element 2 is initially inserted into the bottom of the mounting hole 11, the hook assembly restrains the first stopper 4 on the handle 3 to prevent the filter element 2 from sliding out of the mounting hole 11. The filter element 2 is usually installed. When the user needs to maintain the filter element 2, the filter element 2 must be removed from the mounting hole 11 together with the filter element 2. At this time, the user can rotate the handle 3 around the axis of the rotating shaft 33, so that the first limit block 4 fixed on the handle 3 rotates with the handle 3 around the axis of the rotating shaft 33. Since there is a certain distance between the first limit and the axis of the rotating shaft 33, technicians in this field can adjust the distance between the axis of the rotating shaft 33 and the first limit block 4 at the beginning of the design, so that when the user rotates the handle 3, the first limit block 4 can be out of the limit range of the hook assembly, so that the user can directly lift the handle 3 and pull the filter element 2 out of the mounting hole 11.

[0065] When the filter element 2 is inserted into the bottom of the mounting hole 11, the first stopper 4 on the handle 3 can be limited by the hook assembly. If the hook assembly cannot move, it will be necessary to manually rotate the handle 3 during the process of inserting the filter element 2 into the bottom of the mounting hole 11 so that the first stopper 4 on the handle 3 avoids the hook assembly, thereby avoiding interference between the hook assembly and the first stopper 4 during the process of inserting the filter element 2 into the mounting hole 11. After the filter element 2 is fully inserted into the bottom of the mounting hole 11, the handle 3 is manually rotated again so that the first stopper 4 on the handle 3 swings into the area limited by the hook assembly, thereby preventing the filter element 2 from accidentally exiting the mounting hole 11.

[0066] Although this design allows for a non-threaded connection, and the filter element 2 can be easily inserted into or removed from the mounting hole 11 by adjusting the handle 3, this design still has room for improvement. For example, when the filter element 2 is inserted into the bottom of the mounting hole 11, it is still necessary to manually clear the first stopper 4 and the hook assembly.

[0067] To this end, in one embodiment, the hook assembly includes a first connecting shaft 51, a tension spring 52, a swing arm 53 and a limit hook 54. The first connecting shaft 51 is fixed on the base 1. A first axial hole is opened on the swing arm 53. The first connecting shaft 51 is inserted into the first axial hole. The first axial hole and the first connecting shaft 51 can rotate relative to each other. The limit hook 54 is fixed on the swing arm 53. A limit space is set between the limit hook 54 and the first connecting shaft 51. The limit space is used to hook the first limit block 4 to limit the first limit 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.

[0068] The first connecting shaft 51 is fixed to the base 1, while the swing arm 53 is equipped with a first axial hole. The first connecting shaft 51 and the first axial hole cooperate to allow relative rotation between the swing arm 53 and the first connecting shaft 51. Assuming the depth of the mounting hole 11 is vertical, i.e., in the up-down direction, the length of the first connecting shaft 51 is horizontal, i.e., in the front-back direction. In its initial, neutral state, the swing arm 53's length is also vertical, i.e., extending in the up-down direction, with the stop hook 54 located above the first axial hole.

[0069] When the user needs to insert the filter element 2 into the bottom of the mounting hole 11, the filter element 2 can be inserted into the mounting hole 11. If the first limit block 4 on the handle 3 has not been adjusted to a position that avoids the limit hook 54, then when the first limit block 4 contacts the limit hook 54, the external force applied by the user will push the filter element 2 to move toward the bottom of the mounting hole 11, forcing the limit block and the swing arm 53 connected to it to rotate around the first connecting shaft 51. In the process of the limit block rotating around the first connecting shaft 51, it overcomes the tension of the tension spring 52, causing the tension spring 52 to be stretched. Once the filter element 2 is fully inserted into the bottom of the mounting hole 11, the swing arm 53 will return to its initial position under the action of the elastic restoring force of the tension spring 52. At the same time, the elastic restoring force of the tension spring 52 will also push the first limit block 4 to move it into the limit range of the limit hook 54.

[0070] The length of the tension spring 52 in its natural state may change after long-term use, which may cause the swing arm 53 to be located in a different position in the natural state of the tension spring 52, which will affect the position of the limiting hook 54. It may cause the limiting hook 54 to be unable to limit the first limiting block 4.

[0071] Therefore, in one embodiment, the hook assembly further includes a second stopper 55, which is fixed to the base 1. The tension spring 52 and the second stopper 55 are located on the same side of the swing arm 53. The second stopper 55 is used to limit the swing arm 53 to restrict its travel. In this way, the tension spring 52 can be designed to constantly maintain elastic potential energy, so that the tension spring 52 constantly generates a pulling force on the swing arm 53, so that in a natural state, the swing arm 53 is attached to the second stopper 55, thereby ensuring that the limit hook 54 maintains a fixed position in the natural state.

[0072] When the user inserts the filter element 2 into the bottom of the mounting hole 11, when the first limit block 4 and the limit hook 54 are in contact, the force acting on the limit hook 54 may fail to generate a component force to rotate the limit hook 54 around the first connecting shaft 51 due to the contact angle between the first limit block 4 and the limit hook 54, thereby causing the first limit block 4 and the limit hook 54 to become stuck. To this end, in one embodiment, the surface of the limit hook 54 facing away from the bottom of the mounting hole 11 is called the top surface of the limit hook 54, and a first guide bevel 541 is provided on the top surface of the limit hook 54 near the side of the tension spring 52. This structure is simple and easy to set up. The first guide bevel 541 is provided on the limit hook 54. When the first guide bevel 541 and the first limit block 4 are in contact, a force to rotate the limit hook 54 can be generated through the first guide bevel 541, thereby avoiding the stuck phenomenon.

[0073] To further ensure smooth relative movement between the first limiting block 4 and the first guiding slope 541 when they come into contact, in one embodiment, the first limiting block 4 is provided with a second guiding chamfer 41. The surface of the first limiting block 4 facing the bottom of the mounting hole 11 is referred to as the guiding surface, and the second guiding chamfer 41 is provided on the edge of the guiding surface close to the limiting hook 54. During use, the second guiding chamfer 41 contacts the first guiding slope 541, allowing the limiting hook 54 to rotate about the first connecting shaft 51.

[0074] 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, there is a risk that the swing arm 53 will be separated from the first connecting shaft 51. However, if the limit is applied, the swing arm 53 will no longer be able to separate from the first connecting shaft 51, and the difficulty of its inspection and maintenance will increase. Therefore, in one embodiment, the hook assembly also includes a pressure cover 56, which is detachably connected to the base 1. The pressure cover 56 is used to limit the swing arm 53 along the direction of the first connecting shaft 51. By adopting a detachable mating connection between the pressure cover 56 and the base 1, the pressure cover 56 applies a limit to the swing arm 53 in the axial direction of the first connecting shaft 51, ensuring that the swing arm 53 is on the first connecting shaft 51.

[0075] Optionally, the gland 56 and the base 1 are connected by screws. In addition, the gland 56 and the base 1 can also be connected and fixed by elastic buckles. Of course, these two methods can achieve a detachable and matched connection between the gland 56 and the base 1.

[0076] The positions of the water inlet 23, the concentrated water outlet 24 and the clean water outlet 25 on the water purifier 74 are usually fixed relative to the filter element 2. For example, in some embodiments, the tap water inlet 231, the drinking water outlet 251 and the concentrated water outlet 241 correspond one to one to the water inlet 23, the clean water outlet 25 and the concentrated water outlet 24, respectively. Therefore, after the filter element 2 is inserted into the mounting hole 11, it is necessary to ensure that the relative angle between the filter element 2 and the base 1 remains consistent each time the filter element 2 is inserted into the mounting hole 11. To this end, in one embodiment, a first protrusion 21 is provided on the filter element 2, and a guide groove 12 is provided on the base 1. The guide groove 12 is arranged on the inner wall of the mounting hole 11, and the first protrusion 21 is inserted into the guide groove 12. The first protrusion 21 and the guide groove 12 are slidably fitted. This structure is simple and easy to set up. When the filter element 2 is inserted into the mounting hole 11, the first protrusion 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 protrusion 21, ensuring that the relative angle between the filter element 2 and the base 1 remains consistent each time the filter element 2 is inserted into the mounting hole 11. In addition, the first protrusion 21 and the guide groove 12 cooperate to effectively limit relative rotation between the filter element 2 and the mounting hole 11, especially when the portion of the filter element 2 inserted into the mounting hole 11 is configured as a rotating body, for example, the portion of the filter element 2 inserted into the mounting hole 11 is configured as a cylindrical body.

[0077] The guide groove 12 is used to guide and limit the first protrusion block 21. In order to facilitate the operator to easily insert the first protrusion block 21 into the guide groove 12, in one 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 from shallow to deep along the depth of the mounting hole 11.

[0078] 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 at the entrance of the guide groove 12 is relatively large, and can effectively play a guiding role.

[0079] The handle 3 and filter cartridge 2 are connected by a rotating shaft 33, allowing them to rotate relative to each other. In one embodiment, the rotating shaft 33 is fixed to the handle 3. A first mounting space is defined within the filter cartridge 2, and a second axial hole is defined in the filter cartridge 2, which connects to the first mounting space. The rotating shaft 33 extends through the second axial hole into the first mounting space. This structure is simple and easy to install. Inserting the rotating shaft 33 into the first mounting space ensures a secure connection between the rotating shaft 33 and the filter cartridge 2.

[0080] Furthermore, two second axial holes are provided, and both ends of the handle 3 are inserted into the second axial holes through the rotating shaft 33 in a one-to-one correspondence.

[0081] In one of the above-mentioned embodiments, by rotating the handle 3, the limiting hook 54 can limit the first limiting block 4, so that the filter element 2 is confined in the mounting hole 11. However, during use, once the handle 3 is rotated, the filter element 2 may be instantly unlocked, causing the filter element 2 to accidentally slip out of the mounting hole 11. In one embodiment, the water system further includes a locking block 61, a spring 62, and a button 63. The handle 3 is provided with a slot 31, one end of the spring 62 is connected to the base 1, and the other end of the spring 62 is connected to the button 63. The button 63 and the base 1 are relatively slidably connected, and the locking block 61 is fixed to the button 63, and the locking block 61 is inserted into the slot 31.

[0082] When the first limit block 4 is in a state of being limited by the hook assembly, the filter element 2 will be confined within the mounting hole 11. The handle 3 is provided with a slot 31 for receiving the lock block 61. When the lock block 61 is inserted into the slot 31, the handle 3 is locked and cannot rotate. The lock block 61, spring 62, and button 63 are arranged to lock the handle 3 and prevent it from rotating, so that the handle 3 remains within the range that limits the first limit block 4 to the hook assembly. In addition, the lock block 61 is fixed to the button 63. One end of the spring 62 is connected to the base 1 and the other end is connected to the button 63. The button 63 can slide relative to the base 1. When unlocking is required, the user can press the button 63 to overcome the elastic force of the spring 62, causing the lock block 61 to move out of the slot 31, thereby allowing the handle 3 to rotate. When the button 63 is released, the spring 62 pushes the button 63 and the lock block 61 back into place, relocking the handle 3.

[0083] This effectively enhances safety. The lock block 61 and the slot 31 cooperate to prevent accidental rotation of the handle 3 when not in operation, thereby avoiding the risk of the filter element 2 accidentally slipping out and improving safety during use. Furthermore, operation is convenient: when disassembly or assembly is required, the user simply presses the button 63 to unlock the handle 3, making operation simple and convenient. Furthermore, structural stability is ensured by the use of a spring 62, which ensures that the button 63 and the lock block 61 remain stably locked in the locked position when not in operation, thus ensuring structural stability.

[0084] Assuming that the depth direction of the mounting hole 11 extends in the vertical direction and the first connecting shaft 51 extends in the front-to-back direction, the spring 62 can be extended and contracted in multiple directions such as the vertical direction, the front-to-back direction, or the left-to-right direction. Those skilled in the art can adjust the mounting position according to actual conditions.

[0085] Based on this, in this embodiment, the spring 62 is installed in a direction of expansion and contraction 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, so that the recessed portion 111 forms a first space. 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 locking block 61. A barrier strip is provided at the opening of the recessed portion 111, and the barrier strip separates the opening of the recessed portion 111 to form a first guide hole 1111 and a second guide hole 1112 that are connected to the first space. The locking block 61 is disposed in the first guide hole 1111, and the locking block 61 and the first guide hole 1111 are relatively slidable. The button 63 is inserted into the second guide hole 1112, and the button 63 and the second guide hole 1112 are relatively slidable. A first recessed platform 20 is provided on the surface of the filter element 2 facing away from the mounting hole 11. The first recessed platform 20 extends to a side surface of the filter element 2, and the button 63 faces the side wall of the first recessed platform 20.

[0086] In this embodiment, a recessed portion 111 is provided on the inner wall of the mounting hole 11 to form 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 locking block 61. A barrier strip is provided at the opening of the recessed portion 111 to separate the opening into two guide holes: a first guide hole 1111 and a second guide hole 1112. The locking block 61 is located at the first guide hole 1111 and can slide relative to it. The button 63 passes through the second guide hole 1112 and can also slide relative to it. A first sink 20 is provided on the surface of the filter element 2 facing away from the mounting hole 11, extending to one side of the filter element 2, and the side wall of the button 63 faces the first sink 20.

[0087] Spring 62 provides elastic force, allowing locking block 61 to maintain contact with the inner wall of recess 111 or to move under certain conditions. When locking block 61 is located within first guide hole 1111, it may engage with a specific portion of filter element 2, achieving locking. Pressing button 63 can push locking block 61 to move, thereby unlocking the filter element.

[0088] Because the locking block 61 and the button 63 slide relative to their respective first guide holes 1111 and second guide holes 1112, precise control and positioning can be achieved, ensuring the accuracy and reliability of the locking and unlocking actions. The design of the first sink 20 allows the user's hand to press the button 63 through the sink, making the structure more compact, saving space, and ensuring convenient operation.

[0089] If the first recessed platform 20 is directly opened on the filter element 2, and it is ensured that the depth of the first recessed platform 20 can satisfy the user's pressing of the button 63 located near the inner side surface of the mounting hole 11, it is necessary to set the first recessed platform 20 to a greater depth, which will invisibly increase the height of the filter element 2. To this end, in one embodiment, the handle 3 is arranged in a C-shape, and the two ends of the C-shaped handle 3 are respectively connected to the filter element 2 through the rotating shaft 33. A second recess is provided in the middle of the surface of the handle 3 facing the bottom of the mounting hole 11, and the button 63 extends into the space of the second recess. By setting the second recess, the middle part of the handle 3 is set to be thinner, thereby reducing the obstruction of the button 63 by the handle 3, so that the technician can reduce the depth of the recessed platform accordingly when designing. In addition, by setting the second recess, it meets the ergonomic design and can facilitate the user to hold the handle 3 at the second recess.

[0090] When the filter element 2 needs to be connected to other peripheral parts through plugging or other means, the user often needs to apply a large force to pull out the filter element 2 from the mounting hole 11, making the operation more difficult. In order to facilitate the user to remove the filter element 2 from the mounting hole 11, in one embodiment, a second protrusion block 32 is provided on the handle 3. When the handle 3 is rotated so that the first limit block 4 is disengaged from the hook assembly, the second protrusion block 32 and the base 1 are abutted to drive the filter element 2 to move away from the bottom of the mounting hole 11. When the filter element 2 needs to be removed from the mounting hole 11, the user can rotate the handle 3 so that the second protrusion block 32 on the handle 3 contacts the base 1. By rotating the handle 3, the second protrusion applies pressure to the base 1, forming a force-saving lever mechanism, thereby pushing the filter element 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 element 2, making the disassembly process more convenient.

[0091] The filter element 2 is used to filter raw water. In one embodiment, the filter element 2 includes a housing, a pre-filter material 8, and a reverse osmosis composite filter material 9. The housing is provided with a second installation space, and the pre-filter material 8 and the reverse osmosis composite filter material 9 are both disposed in the second installation space. The tap water inlet 231, the drinking water outlet 251, and the concentrated water outlet 241 are all disposed on the housing. The tap water inlet 231, the drinking water outlet 251, and the concentrated water outlet 241 are all connected to the second installation space. Driven by the booster pump 75, raw water from the raw water tank 72 passes through the water inlet 23 and enters the second installation space from the tap water inlet 231. The raw water entering the second installation space first passes through the pre-filter material 8 to obtain primary filtered water. The primary filtered water is then separated into concentrated water flowing out of the concentrated water outlet 241 and pure water flowing out of the drinking water outlet 251 through the reverse osmosis action of the reverse osmosis composite filter material 9.

[0092] The raw water is initially filtered through the pre-filter material 8 to effectively remove large particles of impurities, suspended matter and some harmful substances in the water, providing a cleaner water source for the reverse osmosis composite filter material 9. The reverse osmosis composite filter material 9 uses reverse osmosis technology to effectively remove dissolved salts, heavy metals, bacteria, viruses and other tiny particles in the water, ensuring that the produced pure water meets the drinking water standard. Combined with the pre-filtration and reverse osmosis composite filter material 9, multiple filtration of the raw water is achieved, improving the filtration efficiency and water quality. The second installation space on the outer shell concentrates the pre-filter material 8 and the reverse osmosis composite filter material 9, making the filter element 2 compact and easy to install and maintain. In a certain embodiment, the first installation space is also set in the second installation space, and the first installation space and the second installation space are independent of each other. Driven by the booster pump 75, the raw water in the raw water tank 72 can pass through the filter element 2 smoothly, ensuring the continuity and stability of the filtration process. After reverse osmosis, the raw water is separated into concentrated water and pure water. The concentrated water is discharged through the concentrated water outlet 241, while the pure water is provided to users through the drinking water outlet 251, thus realizing effective separation and utilization of water.

[0093] The pre-filter material 8 can be used for preliminary filtration of raw water, and can effectively remove large particles of impurities, suspended matter and some harmful substances in the water. In one embodiment, the pre-filter material 8 includes 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 in the direction of water flow. The pre-filter material 8 adopts multi-layer filtration technology. First, the first non-woven fabric 81 effectively intercepts mud, suspended matter and large particles of impurities to ensure the initial purification of the water quality. Then, the scale inhibitor layer 82 plays a role in dispersing insoluble inorganic salts to prevent them from precipitation and scaling, thereby avoiding clogging subsequent filter materials. The third layer uses the first carbon fiber to further remove odors, pigments, residual chlorine and organic matter in the water, improving the taste of the water. The activated carbon 84 layer deeply purifies and removes residual chlorine and organic matter in the water to ensure the purity and safety of drinking water. In addition, the PP melt-blown layer 85 intercepts the front-end carbon powder to prevent it from affecting the performance of subsequent filter materials, ensuring the efficient operation of the entire filtration system.

[0094] The reverse osmosis composite filter material 9 utilizes reverse osmosis technology to effectively remove dissolved salts, heavy metals, bacteria, viruses and other tiny particles in the water, ensuring that the produced pure water meets the drinking water standard. In one embodiment, the reverse osmosis composite filter material 9 includes a reverse osmosis membrane 91, a first filter layer 92, a second carbon fiber layer 93 and a second filter layer 94 in the direction from raw water to raw water. First, the function of the first filter layer 92 is to isolate the carbon fiber from the RO membrane to prevent the RO membrane from being scratched or blocked. Next, the carbon fiber layer is located after the first layer. It deeply removes residual chlorine and organic matter in the water, while increasing the trace elements in the effluent water, thereby significantly improving the taste of the drinking water. Finally, the second filter layer 94 ensures that the particles in the carbon fiber layer will not be lost into the drinking water outlet 251, avoiding the increase in the turbidity of the effluent water and ensuring clear water quality.

[0095] In order to further make the installation structure compact and the space utilization rate high, in one embodiment, the filter element 2 further includes 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 an annular shape, the reverse osmosis composite filter material 9 is arranged in an annular shape, the reverse osmosis composite filter material 9 is arranged on the annular inner side of the annular pre-filter material 8, the upper end cover 26 covers one end of the annular pre-filter material 8 and the annular reverse osmosis composite filter material 9, and the lower end cover 27 covers the annular pre-filter material 8 and the annular reverse osmosis composite filter material 9. At the other end of the filter media 9, the pre-filter media 8 separates the second installation space. An annular first cavity is formed between the pre-filter media 8, the upper end cap 26, the lower end cap 27, and the inner wall of the housing. A second cavity is formed between the pre-filter media 8, the reverse osmosis composite filter media 9, the upper end cap 26, and the lower end cap 27. A third cavity is formed by the inner ring of the annular composite filter media and between the upper end cap 26 and the lower end cap 27. The tap water inlet 231 connects to the first cavity, the concentrated water outlet 241 connects to the second cavity, and the drinking water outlet 251 connects to the third cavity. This structure is compact and highly space-efficient. Within the second installation space, the arrangement of the upper end cap 26 and the lower end cap 27, combined with the annular pre-filter media 8 and the reverse osmosis composite filter media 9, creates a compact layout. This annular design not only fully utilizes the limited space, but the optimized configuration of the upper end cap 26 and the lower end cap 27 further reduces space waste. In addition, the pre-filter material 8 plays a partitioning role in the second installation space, which helps to effectively isolate different types of filter materials and ensure that they work independently, thereby improving the filtration efficiency. The multi-chamber 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. At the same time, the setting of the third cavity ensures the independence of the reverse osmosis process. The optimized design of the fluid channel enables the tap water inlet, the concentrated water outlet and the drinking water outlet to be connected to different cavities respectively, ensuring the reasonable distribution and efficient filtration of the water flow, while avoiding cross contamination. Reasonable cavity design and filter material layout ensure that the water flow undergoes sufficient pre-filtration and reverse osmosis treatment, thereby improving the overall filtration efficiency and water quality. In addition, the setting of the upper end cover and the lower end cover makes the assembly of the filter element convenient and can be easily assembled during the production of the filter element.

[0096] In order to stabilize the water purification load of the water purifier, in one embodiment, a 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 water system is 3:1. If the raw water tank is completely divided into two parts by the partition plate, one part will serve as the raw water tank, occupying 75% of the raw water tank volume, while the other part will serve as the concentrated water tank, occupying 25% of the raw water tank volume. The partition plate should be installed at approximately 1 / 4 of the bottom area of ​​the raw water tank, and its height should match the designed maximum liquid level height. This ensures that the filter element always bears a stable pollution load, that is, the inlet water concentration remains unchanged.

[0097] The above specifically describes the preferred embodiments of the present disclosure, but the present disclosure is not limited to the embodiments. Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the present disclosure, and these equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
