Technical Field
[0001] This utility model relates to the field of water purification technology, and in particular to a filter cartridge device and a water purifier. Background Technology
[0002] Currently, some water purifiers have added a mineral water function, which mainly works by using the principle that minerals will be released from minerals in water.
[0003] If minerals are soaked in water for a long time, the mineral concentration in the water in the filter cartridge will increase, and water with excessively concentrated minerals is not good for drinking.
[0004] Current market solutions include: 1. Reducing the mineral content, which shortens the overall lifespan of the mineral filter cartridge; 2. Recirculating the high-concentration water in the filter cartridge back to the RO membrane for filtration within a certain period of time, which consumes the minerals in the post-carbon filter and extends the lifespan of the RO membrane. Utility Model Content
[0005] This invention provides a filter cartridge device and a water purifier to solve the problem of excessively high mineral concentration in the water within the filter cartridge.
[0006] In a first aspect, the present invention provides a filter cartridge device, the filter cartridge device including a water inlet, a carbon rod core, a water tank and a check valve, the carbon rod core including a first housing and a carbon rod disposed in the first housing; the water inlet is connected to the carbon rod core, the carbon rod core is connected to the water tank through the check valve, wherein the check valve is configured to allow fluid to flow unidirectionally from the carbon rod core to the water tank.
[0007] A further technical solution is that the water tank includes a second shell, and the water inlet is located on the second shell; the carbon rod core is located inside the water tank, and a gap is provided between the carbon rod core and the inner wall of the water tank.
[0008] A further technical solution is that the water tank is provided with a slot, and the slot is connected to the water inlet;
[0009] The first housing has an outwardly protruding insertion port, which can be detachably inserted into the slot.
[0010] A further technical solution is that the filter element device further includes a sealing ring, which is pressed between the outer wall of the insertion port and the inner wall of the slot.
[0011] A further technical solution is that the first shell of the carbon rod core is provided with an outlet, and the check valve is sealed and embedded in the outlet.
[0012] A further technical solution is that the second housing is provided with a water outlet, which is connected to the water tank.

[0016] Secondly, this utility model provides a water purifier, which includes the filter element device as described in the first aspect.
[0017] The technical solution provided by this utility model embodiment has the following advantages compared with the prior art:
[0018] In this invention, the filter element device includes an inlet, a carbon rod, a water tank, and a check valve. The carbon rod includes a first housing and a carbon rod disposed within the first housing. The inlet is connected to the carbon rod, and the carbon rod is connected to the water tank via the check valve. Thus, in the off-state, the soaking water inside the carbon rod is in long-term contact with the carbon rod, resulting in an excessively high concentration of the soaking water, while the non-soaking water in the water tank, not in contact with the carbon rod, has a normal concentration. After soaking and startup, the soaking water comes into contact with the non-soaking water through the check valve, and the high and low concentrations mix to ensure the outlet water always maintains a reasonable concentration. Furthermore, this invention eliminates the need to return high-concentration water to the pre-RO membrane for filtration, thereby preventing the consumption of minerals in the post-filter carbon filter and extending the lifespan of the RO membrane.

[0033] In order to solve the technical problem of excessively high mineral concentration in water in the filter cartridge in the prior art, this utility model provides a filter cartridge device and water purifier that can effectively reduce the mineral concentration in water in the filter cartridge without consuming the minerals of the post-carbon filter or the lifespan of the RO membrane.
[0034] See Figures 1-6 This invention provides a filter cartridge device, which includes an inlet 10, a carbon rod 30, a water tank 40, and a check valve 50. The specific structure is described below:
[0035] The carbon rod core 30 includes a first housing 31 and a carbon rod 32 disposed within the first housing 31. The first housing 31 is used to seal the carbon rod 32, thereby isolating the water inside the carbon rod core 30 from the water in the water tank 40. The carbon rod 32 is used to improve the taste and extract minerals.
[0036] The inlet 10 is connected to the carbon rod core 30 and is used to supply water to the carbon rod core 30. The carbon rod core 30 is connected to the water tank 40 via the check valve 50, wherein the check valve 50 is configured to allow fluid to flow unidirectionally from the carbon rod core 30 to the water tank 40, thereby preventing water from flowing back from the water tank 40 into the carbon rod core 30.
[0037] See Figure 5 Normal operating condition: Pure water flows along the green arrow, specifically in the following order: inlet 10 → carbon rod 32 → check valve 50 → water tank 40 → outlet 20.
[0038] See Figure 6When the machine is stopped, the soaking water 100 (blue area) is in contact with the carbon rod 32 for a long time, resulting in an excessively high concentration of soaking water 100. The non-soaking water 200 (green area) is not in contact with the carbon rod 32 and has a normal concentration.
[0039] After soaking, the system is activated. The soaking water 100 comes into contact with the non-soaking water 200 through the check valve 50. The high concentration and low concentration are mixed to ensure that the water outlet is always at a reasonable concentration.
[0040] In the technical solution of this utility model, the filter element device includes an inlet 10, a carbon rod core 30, a water tank 40, and a check valve 50. The carbon rod core 30 includes a first housing 31 and a carbon rod 32 disposed within the first housing 31. The inlet 10 is connected to the carbon rod core 30, and the carbon rod core 30 is connected to the water tank 40 through the check valve 50. Thus, in the off state, the soaking water in the carbon rod core 30 is in contact with the carbon rod 32 for a long time, resulting in an excessively high concentration of soaking water, while the non-soaking water in the water tank 40 has a normal concentration as it does not come into contact with the carbon rod 32. After soaking and starting, the soaking water comes into contact with the non-soaking water through the check valve 50, and the high and low concentrations are mixed to ensure that the outlet water is always at a reasonable concentration. At the same time, in this utility model, there is no need to return the high-concentration water to the RO membrane for filtration, thus avoiding the consumption of minerals in the post-carbon filter and the lifespan of the RO membrane.
[0041] In some embodiments, such as this one, the water tank 40 includes a second housing 41, and the water inlet 10 is disposed on the second housing 41; the carbon rod core 30 is disposed inside the water tank 40, and a gap is provided between the carbon rod core 30 and the inner wall of the water tank 40.
[0042] Specifically, the second housing 41 is the outer shell of the water tank 40. The water inlet 10 is located on the second housing 41 and is connected to the carbon rod core 30. Water can enter the carbon rod core 30 from the water inlet 10. Furthermore, the water inlet 10 is not connected to the inner cavity of the water tank 40, meaning that water cannot enter the water tank 40 from the water inlet 10.
[0043] The carbon rod core 30 is disposed inside the water tank 40, and a gap is provided between the carbon rod core 30 and the inner wall of the water tank 40. This gap is used to store non-immersion water when the machine is stopped.
[0044] Furthermore, the water tank 40 is provided with a slot 42, which is connected to the water inlet 10; the first housing 31 is provided with an outwardly protruding insertion port 33, which can be detachably inserted into the slot 42.
[0045] Specifically, the insertion port 33 protrudes from the surface of the first housing 31, allowing water to enter the carbon rod core 30 through the insertion port 33. The insertion port 33 is detachably inserted into the slot 42, allowing water to flow from the inlet 10 into the insertion port 33 and then into the carbon rod core 30.
[0046] Furthermore, to prevent water leakage, the filter element device also includes a sealing ring 60, which is pressed between the outer wall of the insertion port 33 and the inner wall of the slot 42.
[0047] Specifically, the sealing ring 60 effectively prevents water from leaking from the insertion port 33 into the water tank 40. The sealing ring 60 can be made of silicone.
[0048] Furthermore, in some embodiments, such as this one, the first housing 31 of the carbon rod core 30 is provided with an outlet, and the check valve 50 is sealed and embedded in the outlet.
[0049] Specifically, the outlet recess is located on the first housing 31, and the check valve 50 is sealed and embedded in the outlet. Under normal operating conditions, water can flow from the carbon rod core 30 through the check valve 50 into the water tank 40. Under shutdown conditions, there is no fluid exchange between the carbon rod core 30 and the water tank 40.
[0050] Furthermore, in some embodiments, such as this embodiment, the second housing 41 is provided with a water outlet 20, which is connected to the water tank 40.
[0051] Specifically, water in the water tank 40 can be discharged outward through the outlet 20. The inlet 10 and the outlet 20 are arranged side by side on the end face of the second housing 41, for example, on the lower end face of the second housing 41, so that the pipelines are connected to the same end face, which facilitates the arrangement of the pipelines.
[0052] Furthermore, in some embodiments, such as this embodiment, the first housing 31 includes a first main housing 311 and a first upper cover 312, the first upper cover 312 covering the first main housing 311.
[0053] Specifically, the first upper cover 312 is sealed to the first main shell 311 to prevent water leakage. At the same time, the first upper cover 312 and the first main shell 311 are detachably connected to facilitate maintenance and replacement of parts.
[0054] Furthermore, in some embodiments, such as this embodiment, the second housing 41 includes a second main housing 411 and a second upper cover 412, the second upper cover 412 covering the second main housing 411.
[0055] Specifically, the second upper cover 412 is sealed to the second main shell 411 to prevent water leakage. At the same time, the second upper cover 412 and the second main shell 411 are detachably connected to facilitate maintenance and replacement of parts.
