Detailed Implementation

[0069] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0070] Water purifiers have a fixed structure, which lacks flexibility in meeting different user needs. This results in limited space for water purifier placement and affects maintenance convenience. If a module in a water purifier is damaged, it is inconvenient to repair and usually needs to be scrapped, resulting in a waste of resources.

[0071] In view of this, the present application provides a modular water purifier, which is equipped with at least one detachable module. The detachable module can be located on the top or side of the main unit, which allows users to flexibly adjust the position of the detachable module according to their needs, thereby improving the flexibility of the modular water purifier. The detachable module is used to change the water temperature flowing to the faucet and / or to prepare pure water into mineral water, making the modular water purifier more versatile.

[0072] The following description, with reference to the accompanying drawings, describes a combined water purifier provided in an embodiment of the present invention.

[0073] Referring to Figure 1, this application provides a combined water purifier, including: a main unit 10, a faucet 20 and at least one detachable module. The main unit 10 includes a filter unit 13 and a water storage tank 14. The main unit 10 has a raw water inlet 111 and a pure water outlet 112. The filter unit 13 and the water storage tank 14 are connected in series between the raw water inlet 111 and the pure water outlet 112.

[0074] The faucet 20 is located outside the main unit 10. The faucet 20 is connected to the pure water outlet 112. The faucet 20 is equipped with a first heating component 21, which is configured to heat the water flowing through the faucet 20.

[0075] Referring to Figures 2 and 3, the detachable module is located on the top of the main unit 10 or on the side of the main unit 10. The detachable module is connected between the main unit 10 and the faucet 20. The detachable module is used to change the water temperature flowing to the faucet 20 and / or to prepare pure water into mineral water.

[0076] This application provides a modular water purifier, which includes at least one detachable module. The detachable module can be located on the top or side of the main unit 10, allowing users to flexibly adjust the position of the detachable module according to their needs, thereby improving the flexibility of the modular water purifier. The detachable module is used to change the water temperature flowing to the faucet 20 and / or to prepare pure water into mineral water, making the modular water purifier more versatile.

[0077] Referring to Figures 1 and 4, a signal line 102 is electrically connected between the faucet 20 and the main unit 10.

[0078] Referring to Figure 1, the combined water purifier provided in this application includes a first heating component 21 installed inside the faucet 20. The first heating component 21 is configured to heat the water flowing through the faucet 20, making it convenient to use. The first heating component 21 can be a wire-wound heating module, which heats up after being powered on, thereby heating the water flowing through the faucet 20.

[0079] Referring to Figures 2 and 3, this application provides a combined water purifier. The detachable module may include only the mineral water module 30, or it may include only the temperature control module 40, or it may include both the mineral water module 30 and the temperature control module 40.

[0080] In one possible implementation, the temperature control module 40 can also be adapted for use with other water purifiers. The mineral water module 30 can also be adapted for use with other water purifiers.

[0081] In one possible implementation, referring to FIG1, the filtration unit 13 includes at least one first filter element 133 for filtering and purifying the raw water entering the host 10 from the raw water inlet 111, and the pure water outlet 112 for supplying the obtained pure water to flow out of the host 10.

[0082] In one possible implementation, the filter unit 13 may include two, three, or more first filter elements 133 connected in series to achieve multi-stage filtration, which helps to improve the filtration effect. The two, three, or more first filter elements 133 connected in series may use the same filter material or different filter materials, which is not specifically limited here.

[0083] In one possible implementation, the filter unit 13 and the water storage tank 14 are connected in series between the raw water inlet 111 and the pure water outlet 112. The raw water entering the host 10 from the raw water inlet 111 is filtered and purified by the filter unit 13, and the obtained pure water flows out from the pure water outlet 112.

[0084] In one possible implementation, referring to Figure 1, the main unit 10 further includes a water inlet valve 16 and a booster pump 17. The water inlet valve 16 and the booster pump 17 can be connected in series between the raw water inlet 111 and the filter unit 13, or they can be connected in series between two adjacent first filter elements 133 in the filter unit 13. The water inlet valve 16 can be a solenoid valve to facilitate the control of the opening and closing of the pipeline supplying water to the inside of the main unit 10 through the raw water inlet 111.

[0085] To prevent bacteria from growing inside the water storage tank 14, a sterilization device 145 is installed inside the water storage tank 14. The sterilization device 145 can be an ultraviolet light-emitting diode (also known as an ultraviolet LED or UV-LED), which sterilizes and disinfects the water storage tank 14.

[0086] Of course, the sterilization device 145 can also be an ozone generator. The ozone generator can generate ozone to sterilize and disinfect the water storage tank 14 and the connected pipes, ensuring that the water storage tank 14 is clean and avoiding safety and health problems caused by the growth of bacteria inside.

[0087] In one possible implementation, a liquid level detection device 143 is provided inside the water storage tank 14. There may be two liquid level detection devices 143, which are used to detect the highest liquid level and the lowest liquid level, respectively.

[0088] In one possible implementation, a water quality detection device 144 is also installed inside the water storage tank 14 to detect the water quality of the water stored in the water storage tank 14.

[0089] In one possible implementation, the capacity of the water tank 14 can be 5L to 6L.

[0090] In one possible implementation, referring to Figure 1, the detachable module includes a mineral water module 30, which is connected in series between the filter unit 13 and the water storage tank 14. The mineral water module 30 is used to prepare mineral water from the pure water flowing through it. The raw water entering the main unit 10 from the raw water inlet 111 is filtered and purified by the filter unit 13 to obtain pure water. The pure water then flows to the mineral water module 30, where it is prepared into mineral water. The prepared mineral water is collected in the water storage tank 14 for user use.

[0091] In one possible implementation, the mineral water module 30 contains specially treated mineral stones. As pure water flows through the mineral stones, the minerals and trace elements contained in the mineral stones dissolve into the pure water, thereby producing mineral water.

[0092] In one possible implementation, the mineral water module 30 has a mineral water inlet 31 and a mineral water outlet 32, the filtration unit 13 has a purified water outlet 131, and the water storage tank 14 has a water tank inlet 141. The mineral water inlet 31 is connected to the purified water outlet 131, and the mineral water outlet 32 ​​is connected to the water tank inlet 141. The purified water outlet 131 is used to supply pure water filtered by the filtration unit 13, the mineral water inlet 31 is used to supply water into the mineral water module 30, and the mineral water outlet 32 ​​and the water tank inlet 141 can be connected by a water pipe, so that the prepared mineral water is collected in the water storage tank 14.

[0093] In one possible implementation, referring to FIG1, the main unit 10 also includes a detachably configured straight-through pipe connector 12, which connects the purified water outlet 131 and the water tank inlet 141.

[0094] In one possible implementation, when the detachable module of the combined water purifier does not include the mineral water module 30, the straight pipe joint 12 keeps the purified water outlet 131 connected to the water tank inlet 141, and the purified water flowing out of the purified water outlet 131 enters the water storage tank 14 through the water tank inlet 141 for storage.

[0095] In one possible implementation, when the detachable module of the combined water purifier, including the mineral water module 30, is combined and connected with the main unit 10, the straight pipe connector 12 is removed, so that the mineral water inlet 31 is connected to the purified water outlet 131, and the mineral water outlet 32 ​​is connected to the water tank inlet 141, while the purified water outlet 131 and the water tank inlet 141 are no longer connected. This ensures that the water flowing out of the purified water outlet 131 will flow to the mineral water module 30, guaranteeing the effective preparation of mineral water. The prepared mineral water flows from the mineral water outlet 32 ​​to the water tank inlet 141 and is collected in the water storage tank 14.

[0096] In one possible implementation, the detachable module includes a temperature control module 40 connected in series between the water tank 14 and the faucet 20. The temperature control module 40 is used to regulate the temperature of the water flow so that the temperature of the water flowing from the faucet 20 meets more usage requirements.

[0097] In one possible implementation, the temperature control module 40 includes at least one of a heating unit 41 and a cooling unit 42, wherein the heating unit 41 is configured to heat the water flow passing through it, and the cooling unit 42 is configured to cool the water flow passing through it. Alternatively, the temperature control module 40 may also include both a heating unit 41 and a cooling unit 42.

[0098] In one possible implementation, the heating unit 41 includes a first water tank and a heating element that generates heat when energized, heating the water in the first water tank. The first water tank is also connected to an exhaust pipe 50, one end of which can be an extension to the drain outlet 22 of the faucet 20. The exhaust pipe 50 is used to promptly discharge the steam generated by heating the water in the first water tank, improving safety during use.

[0099] In one possible implementation, the heating element is a cast aluminum heating element or a thick film heating element, which is reasonably designed and has high practical value.

[0100] In one possible implementation, the cooling unit 42 includes a second water tank and an electronic ice chamber. Cooling is achieved using the Pelche effect. The cooling chip in the electronic ice chamber contains numerous thermocouples composed of interconnected P-type and N-type semiconductor elements. When direct current is applied, the hot ends of the semiconductor elements release heat, and the cold ends absorb heat, creating a temperature difference. The cold ends then contact the second water tank, absorbing heat from the water stored within, causing the water temperature in the second tank to continuously decrease, thereby achieving the purpose of controlling the water temperature.

[0101] In one possible implementation, the temperature control module 40 is connected in series between the water storage tank 14 and the faucet 20.

[0102] In one possible implementation, referring to Figure 1, the faucet 20 has a drain outlet 22, and the water storage tank 14 is connected to the drain outlet 22 of the faucet 20 via a first pipe 61 and a second pipe 62 arranged in parallel. The first pipe 61 and the second pipe 62 can be either a hot water pipe or a normal temperature water pipe or a cold water pipe.

[0103] In this example, the first pipe 61 is a hot water pipe, the second pipe 62 is a normal temperature water pipe or a cold water pipe, and the first heating component 21 can be installed on the outer wall of the first pipe 61 to heat the water flowing through the first pipe 61.

[0104] In one possible implementation, a temperature measuring device 23 is also provided inside the faucet 20. The temperature measuring device 23 is located in the first pipe 61. There are two temperature measuring devices 23, which are used to detect the water temperature before the first heating element 21 heats the water and the water temperature after the first heating element 21 heats the water. The temperature measuring device 23 can be a thermistor (Negative Temperature Coefficient, abbreviated as NTC).

[0105] In one possible implementation, a first check valve 613, a first water pump 611, and a flow switch 612 are connected in series on the first pipe 61. A second water pump 621 and a second check valve 622 are connected in series on the second pipe 62.

[0106] In one possible implementation, referring to Figure 1, the water tank 14 also has a water tank outlet 142, the heating unit 41 has a heating inlet 411 and a heating outlet 412, the heating inlet 411 is connected to the water tank outlet 142, the pure water outlet 112 is connected to the faucet 20 by a first pipe 61, and the heating outlet 412 is connected to the first pipe 61.

[0107] Referring to Figures 1 and 6, when the temperature control module 40 includes a heating unit 41 but not a cooling unit 42, the water stored in the water storage tank 14 flows out of the water storage tank 14 through the water tank outlet 142, and then enters the first water tank of the heating unit 41 through the heating inlet 411. The hot water heated by the heating unit 41 flows to the faucet 20 through the first pipe 61 to provide hot water to the user. The heating unit 41 provides hot water to the faucet 20, thereby increasing the hot water flow rate of the faucet 20.

[0108] In one possible implementation, the temperature control module 40 can be used independently and is compatible with other water purifier products.

[0109] In one possible implementation, the water tank 14 has a water tank outlet 142, the refrigeration unit 42 has a refrigeration inlet 421 and a refrigeration outlet 422, the refrigeration inlet 421 is connected to the water tank outlet 142, a second pipe 62 is connected between the pure water outlet 112 and the faucet 20, the second pipe 62 is connected in parallel with the first pipe 61 between the water tank outlet 142 and the faucet 20, and the refrigeration outlet 422 is connected to the second pipe 62.

[0110] Referring to Figures 1 and 7, when the temperature control module 40 includes a cooling unit 42 but does not include a heating unit 41, the water stored in the water storage tank 14 flows out of the water storage tank 14 from the water tank outlet 142, and then enters the second water tank of the cooling unit 42 through the cooling inlet 421.

[0119] In one possible implementation, adjacent components of the main unit 10, mineral water module 30, and temperature control module 40 can be magnetically attracted or connected by snap-fit ​​mechanisms to improve the stability of their fixation. For example, a first magnetic component can be provided on the side of the main unit 10's casing facing the mineral water module 30, and a second magnetic component can be provided on the side of the mineral water module 30 facing the main unit 10. The magnetic attraction between the first and second magnetic components improves the relative stability of the main unit 10 and the mineral water module 30.

[0122] In one possible implementation, the water tank outlet 142 and the wastewater outlet 15 are connected by a pipe, and a drain valve 19 is provided on the pipe between the water tank outlet 142 and the wastewater outlet 15 to prevent the water stored in the water tank 14 from overflowing.

[0123] In one possible implementation, referring to Figures 8, 9 and 10, the mineral water module 30 includes a housing 33 and a mineral water filter element 34. The housing 33 has an internal mounting cavity 331. The mineral water filter element 34 is detachably disposed in the mounting cavity 331. The mineral water filter element 34 is provided with a locking component 70, which locks the mineral water filter element 34 in the mounting cavity 331.

[0124] With this structure, when the locking component 70 is in the locked state, the mineral water filter element 34 is locked in the mounting cavity 331, achieving a stable installation and fixation of the mineral water filter element 34. When the locking component 70 is in the unlocked state, the mineral water filter element 34 can be removed from the mounting cavity 331, making it easy to disassemble and replace the mineral water filter element 34 and reducing replacement costs.

[0125] The mounting cavity 331 can be cylindrical or cubic, and the shape of the mineral filter element 34 is adapted to the shape of the mounting cavity 331.

[0126] In one possible implementation, referring to Figures 8 and 10, the main unit 10 includes a main unit housing 11, the main unit housing 11 having a receiving cavity 113 inside, and the filter unit 13 including at least one first filter element 133 removably disposed in the receiving cavity 113, the first filter element 133 being provided with a locking component 70, the first filter element 133 being locked in the receiving cavity 113 by the locking component 70.

[0127] This structure secures the first filter element 133 by locking the locking component 70 and allows the first filter element 133 to be disassembled by unlocking the locking component 70, making it easy to disassemble and replace the first filter element 133 and reducing replacement costs.

[0128] The accommodating cavity 113 can be cylindrical or cubic, and the shape of the first filter element 133 is adapted to the shape of the accommodating cavity 113.

[0129] In one possible implementation, the number of first filter elements 133 may be one, two or more, and each first filter element 133 is locked in the receiving cavity 113 by a corresponding locking component 70.

[0130] In one possible implementation, referring to Figures 9 and 10, the locking assembly 70 includes a connecting seat 71, a locking element 72, a drive unit 73, and a linkage unit 74. The connecting seat 71 is configured to connect to the end face of the mineral filter element 34 or the first filter element 133.

[0131] Referring to Figures 10, 11, and 12, the locking member 72 is slidably disposed on the connecting seat 71; the driving unit 73 includes a decorative member 731 and a hand-held member 732, the decorative member 731 is connected to the connecting seat 71, and an opening 734 is formed between the decorative member 731 and the connecting seat 71, the hand-held member 732 is movably disposed within the opening 734; the linkage unit 74 is disposed between the locking member 72 and the driving unit 73, and the linkage unit 74 is configured to drive the locking member 72 to slide on the connecting seat 71 under the pulling force of the hand-held member 732, so that the locking member 72 protrudes from the outer peripheral surface of the locking assembly 70.

[0132] The connecting seat 71 secures the locking component 70. The connecting seat 71 can be connected to the end face of the mineral water filter element 34 or the first filter element 133 by means of threaded engagement, or it can be connected to the end face of the mineral water filter element 34 and / or the first filter element 133 by means of snap-fit ​​connection or screw connection.

[0133] The decorative part 731 serves a decorative purpose, covering the gripper 732. The decorative part 731 also limits the movement of the gripper 732, preventing it from coming off.

[0134] The driving force of the driving unit 73 drives the linkage unit 74 to move. The linkage unit 74 drives the locking member 72 to slide, so that the locking member 72 slides relative to the connecting seat 71. When the locking member 72 slides out of the connecting seat 71, it locks. When the locking member 72 retracts to the connecting seat 71, it unlocks.

[0135] In one possible implementation, referring to Figures 10, 11, and 13, the linkage unit 74 includes a swing mechanism 75 and a linkage mechanism 76. The swing mechanism 75 includes a base 751 and a swing arm 752. The base 751 is fixedly connected to the connecting seat 71, and the swing arm 752 is oscillatingly disposed within the base 751. The linkage mechanism 76 includes a first link 761 and a second link 762. The first link 761 is rotatably disposed on the connecting seat 71. The first end of the first link 761 is rotatably connected to the first end of the second link 762. The second end of the first link 761 extends to the side of the swing arm 752 opposite to the hand gripper 732. The second end of the second link 762 is rotatably connected to the locking member 72.

[0136] In one possible implementation, the base 751 can be fixedly connected to the connector 71 by means of screws or bolts, or it can be fixedly connected to the connector 71 by means of snap-fit ​​connection.

[0137] In one possible implementation, as shown in Figures 10, 11 and 15, the swing arm 752 has connecting shafts 7522 on both sides, and the base 751 has connecting holes. The connecting shafts 7522 are rotatably disposed in the connecting holes, so that the swing arm 752 is oscillatingly disposed in the base 751.

[0138] When the swing arm 752 swings, it presses the second end of the first link 761, causing the first end of the first link 761 to lift up. The first link 761 drives the second link 762 to rotate, causing the second link 762 to drive the locking member 72 to slide.

[0139] In one possible implementation, referring to Figures 10, 11, and 13, the first connecting rod 761 has fixed shafts 7611 at both ends, and the connecting seat 71 has a support portion 713 with a fixing hole inside. The fixed shafts 7611 are rotatably connected to the fixing holes in the support portion 713, so that the first connecting rod 761 is rotatably mounted on the connecting seat 71 about the fixed shafts 7611. The rotation axis of the first connecting rod 761 is perpendicular to the rotation axis of the swing arm 752.

[0140] The first link 761 is strip-shaped, with the first end and the second end of the first link 761 being the two ends of the length direction of the first link 761, and the fixed shaft 7611 being located between the first end and the second end of the first link 761.

[0141] The second link 762 is strip-shaped, with the first end and the second end of the second link 762 being the two ends of the length direction of the second link 762, respectively.

[0142] In one possible implementation, the first end of the first link 761 may be provided with an optical shaft, and the first end of the second link 762 may be provided with a through hole. By inserting the optical shaft into the through hole, the first end of the first link 761 is rotatably connected to the first end of the second link 762. Alternatively, the first end of the first link 761 may be provided with a through hole, and the first end of the second link 762 may be provided with an optical shaft. By inserting the optical shaft into the through hole, the first end of the first link 761 is rotatably connected to the first end of the second link 762.

[0143] In one possible implementation, referring to Figures 12, 14 and 15, the gripper 732 includes a gripping portion 7321 and a hook portion 7322 connected to the edge of the gripping portion 7321, forming a receiving space 7323 between the hook portion 7322 and the gripping portion 7321, a first end of a swing arm 752 extending into the receiving space 7323, and a second end of the swing arm 752 abutting against the second end of a first link 761.

[0144] The hook 7322 is used to hook the first end of the swing arm 752, so that when the user pulls the lever 732, the lever 732 drives the swing arm 752 to rotate as a whole, so that the second end of the swing arm 752 drives the first connecting rod 761 to move. Referring to Figure 16, in order to facilitate the hook 7322 to hook the first end of the swing arm 752, the first end of the swing arm 752 is provided with a protrusion 7523, which extends toward the connecting seat 71, and the hook 7322 hooks onto the end of the protrusion 7523 near the connecting seat 71.

[0145] In one possible implementation, referring to Figures 10, 11 and 13, the connecting seat 71 is provided with a slide groove 711, and there are two locking members 72. The two locking members 72 are slidably disposed in the slide groove 711, and a first elastic member 77 is disposed between the two locking members 72.

[0146] The side of the connecting seat 71 facing away from the mineral water filter element 34 or the first filter element 133 is the mounting surface 715. The locking member 72 is slidably disposed on the mounting surface 715 of the connecting seat 71, and the slide groove 711 is located on the mounting surface 715.

[0147] In this application, there are two locking elements 72, which helps to improve the locking effect of the locking elements 72 and thus improve the stability of the locking assembly 70. The first elastic element 77 is used to push the two locking elements 72 away from each other, which helps the two locking elements 72 to extend from the edge of the connecting seat 71 and improve the stability of the locking.

[0148] In one possible implementation, one of the two locking members 72 is provided with a guide rod 722, and the other locking member 72 is provided with a guide hole. The guide rod 722 passes through the guide hole, and a first elastic member 77 is sleeved on the outer peripheral surface of the guide rod 722, with the two ends of the first elastic member 77 respectively abutting against the two locking members 72.

[0149] The guide rod 722 can have a cylindrical or rectangular cross-sectional shape. The shape of the guide hole is consistent with the cross-sectional shape of the guide rod 722. The guide rod 722 passes through the guide hole. Through the cooperation between the guide rod 722 and the guide hole, the relative movement of the two locking parts 72 is guided, which helps to prevent the two locking parts 72 from deflecting or jamming during movement, and ensures that the two locking parts 72 slide smoothly relative to each other.

[0150] In one possible implementation, both ends of the slide groove 711 are provided with first limiting portions 714, and the locking member 72 is provided with a second limiting portion 724, which abuts against the first limiting portions 714. This structure is used to prevent the locking member 72 from disengaging from the slide groove 711.

[0151] In one possible implementation, the first limiting part 714 may be a stop protrusion extending into the slide groove 711, and the second limiting part 724 may be a protrusion that cooperates with the first limiting part 714, so that when the second limiting part 724 and the first limiting part 714 abut against each other, the locking member 72 stops sliding and the movement of the locking member 72 is limited.

[0152] In one possible implementation, the first elastic element 77 can be an elastic sleeve or a compression spring.

[0153] In one possible implementation, to facilitate the rotatable connection of the second end of the second link 762 to the locking member 72, the locking member 72 also has an ear plate 725. The ear plate 725 is located on one side of the locking member 72 opposite to the protrusion 721. One of the ear plate 725 and the second end of the second link 762 is provided with a connecting post 7621, and the other is provided with a rotating hole 7251. By extending the connecting post 7621 into the rotating hole 7251, the second end of the second link 762 is rotatably connected to the locking member 72.

[0154] In one possible implementation, the connecting seat 71 is further provided with a fixing post 712, and the second end of the swing arm 752 has a clearance hole 7521 for the fixing post 712 to pass through. A second elastic member 78 is sleeved on the fixing post 712, and the two ends of the second elastic member 78 abut against the connecting seat 71 and the swing arm 752 respectively. Sleeving the second elastic member 78 on the fixing post 712 can prevent the second elastic member 78 from falling out and improve the stability of the installation of the second elastic member 78.

[0155] In one possible implementation, the fixed column 712 can be a cylindrical or rectangular column.

[0156] In one possible implementation, the second elastic element 78 can be a spring or an elastic sleeve. The second elastic element 78 is used to push the second end of the swing arm 752, causing the second end of the swing arm 752 to move in a first direction. When the user releases the gripper 732, the swing arm 752 is pushed back to its original position. The first direction is referenced to the direction indicated by the Y-axis in FIG10.

[0157] In one possible implementation, referring to Figures 10, 12 and 14, the locking assembly 70 further includes a shield 79, which is fixedly connected to the base 751 and serves to shield the base 751 and the swing arm 752 for aesthetic purposes.

[0158] In one possible implementation, the shield 79 and the base 751 can be connected by screws, bolts, or other fasteners.

[0159] In one possible implementation, referring to Figures 8, 9, and 10, one end of the main housing 11 has an opening communicating with the receiving cavity 113. The inner wall of the receiving cavity 113 has a first locking hole 114, and the locking member 72 has a protrusion 721 that extends into the first locking hole 114. This achieves position locking of the first filter element 133.

[0160] The first locking hole 114 is located on the inner walls of opposite sides of the accommodating cavity 113 and is connected to the locking assembly 70 of the first filter element 133. The protrusions 721 of the two locking members 72 extend into the two first locking holes 114 respectively.

[0161] The slide groove 711 extends along the second direction, and the two locking members 72 are slidably disposed relative to each other along the second direction. A first elastic member 77 disposed between the two locking members 72 is used to push the two locking members 72 away from each other, so that the protrusions 721 of the two locking members 72 extend out from both sides of the connecting seat 71. Under the elastic force of the first elastic member 77, the two locking members 72 remain relatively far apart, improving the locking effect of the locking assembly 70. The second direction is referred to as the direction indicated by the X-axis in Figure 10.

[0162] In one possible implementation, the end of the protrusion 721 away from the first elastic member 77 may be pointed, which helps to extend the protrusion 721 into the first locking hole 114.

[0163] In one possible implementation, one end of the housing 33 has an opening communicating with the mounting cavity 331, the inner wall of the mounting cavity 331 has a second locking hole 332, and the locking member 72 has a protrusion 721 that extends into the second locking hole 332, thereby achieving position locking of the mineral filter element 34.

[0164] The second locking holes 332 are located on the inner walls of opposite sides of the mounting cavity 331 and are connected to the locking assembly 70 of the mineral water module 30. The protrusions 721 of the two locking members 72 extend into the two second locking holes 332 respectively.

[0165] In use, the user grasps the gripping part 7321 and pulls the entire hand-grip piece 732 to move along the first direction. The hook part 7322 drives the first end of the swing arm 752 to move along the first direction with the hand-grip piece 732, causing the swing arm 752 to rotate. The second end of the swing arm 752 moves in the opposite direction to the first direction. The second end of the swing arm 752 drives the second end of the first connecting rod 761 to move in the opposite direction to the first direction, causing the first connecting rod 761 to rotate around the fixed axis 7611. The distance between the first end of the first connecting rod 761 and the connecting seat 71 increases in the first direction. The second connecting rod 762 changes from a horizontal state to an inclined state or a vertical state, causing the second connecting rod 762 to pull the locking piece 72 to slide along the second direction. The two locking pieces 72 move closer to each other, and the protrusion 721 retracts from the first locking hole 114 or the second locking hole 332, thus unlocking the locking component 70.

[0166] This application provides a combined water purifier that can effectively filter out bacteria, germs, toxins, heavy metals and other impurities from water, thereby improving the health of drinking water.

[0167] The present application provides a combined water purifier, which, by setting a locking component 70, makes it very convenient to disassemble and replace the first filter element 133 and the mineral water filter element 34. The first filter element 133 and the mineral water filter element 34 can be used independently, improving the convenience of use.

[0168] This application provides a modular water purifier that allows users to flexibly adjust the position of detachable modules according to their needs, improving the flexibility of use and making the modular water purifier more versatile. When the user selects the standard configuration, it does not include the mineral water module 30 and can function as an under-sink water purifier. If the user wants to produce mineral water, they can simply connect the mineral water module 30 to the standard configuration modular water purifier.
