Technical Field

[0001] The utility model relates to the field of water purifiers, in particular to a water purifier and a water passage structure of a filter element module of the water purifier. Background Art

[0002] Water purifiers are common water filtration devices today, and they have multiple filter cartridges that can produce direct drinking water through multiple filtration. Currently, the layout and use of multiple filter cartridges are very rigid. All filter cartridges need to be installed for the machine to work properly. Once a filter cartridge needs to be removed, the machine cannot be used. For example, the post-filter cartridge at the end of the multiple filter cartridges improves the taste of filtered water by filling it with filter carbon and some mineral elements such as strontium and sodium. However, some users find that they do not like the improved taste brought by the post-filter cartridge after using the water purifier at home. At this time, the post-filter cartridge cannot be removed and they can only return the product and purchase a machine without the post-filter cartridge. Summary of the Invention

[0022] Reference Figures 1 to 4 A water flow structure of a filter element module includes a filter element warehouse 2 for installing a filter element 1, a water inlet nozzle 31 and a water outlet nozzle 32, the end of the filter element warehouse 2 in the insertion direction is provided with a first water flow port 5 and a second water flow port 6 connected to the filter element water inlet 11 and the filter element water outlet 12, the first water flow port 5 and the second water flow port 6 are connected to the water inlet nozzle 31 and the water outlet nozzle 32 through a first water passage 7 and a second water passage 8, and a third water passage 9 is provided between the first water passage 7 and the second water passage 8.

[0023] The first water passage 7 is also provided with a movable valve assembly 4, which has a first state and a second state and is provided with a trigger member 44 that penetrates into the filter element compartment 2; when the filter element 1 is not installed in the filter element compartment 2, the movable valve assembly 4 is normally in the first state, closing the connection between the first water port 5 and the first water passage 7 and enabling the first water passage 7 to be connected to the second water passage 8 through the third water passage 9. At this time, in the absence of the filter element 1 being connected, the water inlet nozzle 31 can still be connected to the water outlet nozzle 32 to maintain water flow. When the filter element 1 is completely installed into the filter element compartment 2 so that the filter element water inlet 11 is connected to the first water outlet 5, the trigger member 44 is pushed to make the movable valve assembly 4 enter the second state, closing the connection between the first water channel 7 and the third water channel 9, so that the first water channel 7 is connected to the first water outlet 5. At this time, the water entering the water inlet nozzle 31 enters the filter element water inlet 11 through the first water channel 7 and the first water outlet 5. After passing through the filtered water channel inside the filter element 1, the water is discharged from the filter element water outlet 12, the second water channel 8, and the water outlet nozzle 32.

[0024] Reference Figure 5A water purifier includes a filter cartridge module, a water outlet module, and a water inlet module arranged in a body. The filter cartridge module has multiple filter cartridge compartments 2 for installing multiple filter cartridges. Each filter cartridge compartment 2 is respectively provided with a water inlet nozzle 31 and a water outlet nozzle 32. The multiple filter cartridge compartments 2 are arranged in sequence and connected to adjacent filter cartridge compartments 2 through their respective water inlet nozzles 31 and water outlet nozzles 32, so that the multiple filter cartridges are connected in sequence. That is, the water inlet nozzle 31 of the filter cartridge compartment 2 in the initial position is connected to the water inlet module, and its water outlet nozzle 32 is connected to the water inlet nozzle 31 of the next filter cartridge compartment 2, and the water outlet nozzle 32 of the next filter cartridge compartment 2 is connected to the water inlet nozzle 31 of the next filter cartridge compartment 2, and so on until the water outlet nozzle 32 of the filter cartridge compartment 2 in the last position is connected to the water outlet module. At least one filter cartridge compartment 2 adopts the above-mentioned water flow structure.

[0025] For example: the last filter cartridge compartment 2 is used to install the post-filter cartridge, which is a post-filter cartridge compartment. Since some users do not like the taste of water improved by the post-filter cartridge, when the last post-filter cartridge compartment adopts the above-mentioned water-passing structure, the post-filter cartridge can be removed according to user needs without affecting the use of the entire machine, and the entire filter cartridge module is still kept connected, avoiding the situation in the past where the entire machine cannot work normally once a filter cartridge is removed.

[0026] Of course, when the filter element module has more auxiliary filter elements such as post-filter elements, the filter element compartment 2 for installing such filter elements can adopt the above-mentioned water-passing structure, and users can choose the filter elements with the required functions to install and use, thereby making the use of the water purifier more flexible and matching more user needs.

[0027] As a preferred embodiment of the present invention, the movable valve assembly 4 includes a movable valve core 41, an elastic member 42 and a valve seat 43; the valve seat 43 has a water passage cavity 431 and the inner wall of the water passage cavity 431 is provided with a third water passage 432, the first water passage 7 is connected to the third water passage 9 through the water passage cavity 431 and the third water passage 432; the movable valve core 41 is movably connected to the first water passage 7 and the two ends are respectively a first blocking portion 411 facing the first water passage 5 and a second blocking portion 412 facing the valve seat 43. 12; The elastic member 42 acts between the movable valve core 41 and the valve seat 43. The movable valve core 41 is moved toward the first water port 5 by the elastic member 42, so that the first blocking portion 411 blocks the first water port 5, forming the first state of the movable valve assembly 4; the trigger member 44 is provided on the movable valve core 41. The trigger member 44 drives the movable valve core 41 to overcome the action of the elastic member 42 and move toward the valve seat 43, so that the second blocking portion 412 and the water passage cavity 431 form the second state of the movable valve assembly 4. Furthermore, the trigger member 44 passes through the first water port 5 to the interior of the filter cartridge compartment 2, and no additional through-hole is required for the trigger member 44 to pass through.

[0028] Preferably, parts of the first water channel 7 and the second water channel 8 are arranged in the same direction as the insertion direction of the filter element compartment 2 to form a vertical section, and the movable valve assembly 4 is arranged in the vertical section of the first water channel 7, and the first water port 5 and the second water port 6 are ports of the vertical sections of the first water channel 7 and the second water channel 8. The second water port 6 is located in the first water port 5 and is coaxially arranged, cooperating with the current mainstream filter element interface structure in the market, and utilizing the vertical section to match the installation direction of the filter element 1 while facilitating the arrangement of the movable valve assembly 4, so that the structure of the movable valve assembly 4 can be simpler and can efficiently contact the filter element 1 to be triggered.
