Detailed Description
The present embodiment is a household water purifier, as shown in fig. 1, in which a filter element module 100 is mounted on a base 200 to form a water purifier, and in this embodiment, an RO reverse osmosis membrane water purifier is provided, which has four filter element modules 100 mounted on the base 200, respectively a PP cotton filter element, a front activated carbon filter element, an RO reverse osmosis membrane filter element and a rear activated carbon filter element, and a booster pump 300 is further provided on the base 200, so that raw water (tap water) sequentially passes through the PP cotton filter element under the resultant force of the pressure of the raw water and the booster pump 300, and the front activated carbon filter element, the RO reverse osmosis membrane filter element and the rear activated carbon filter element are filtered, and in this stage, the RO reverse osmosis membrane filter element has two output ports, one of which is a waste water outlet, directly discharged from the waste water outlet on the base 200, and the purified water outlet flows into the rear activated carbon filter element through a pipe in the base 200 to be filtered, and then discharged through the waste water outlet on the base 200.
As shown in fig. 2 and 3, the filter core module 100 is formed by wrapping the filter core 120 with the mold shell 110, in this embodiment, in order to facilitate the installation and after-sales service of the water purifier, the mold shell 110 is identical, only the filter core 120 inside the mold shell is different, and the PP cotton filter core, the activated carbon filter core, the RO reverse osmosis membrane filter core and the post-positioned activated carbon filter core are respectively arranged, so that different filter core modules 100 are formed, but the filter core modules 100 are identical in appearance, and in practice, in other water purifier products of the inventor, the mold shell 110 is not required to be identical in size, only the mold shell 110 is required to have the same head 111, and the mold core module is matched with the filter core mounting seat 210 on the base 200. In addition, a booster pump 300 is installed on the base 200, and like the cartridge module 100, the booster pump 300 is also installed vertically, with its water inlet and water outlet respectively communicating with the corresponding waterway in the base 200.
In this embodiment, in order to make the appearance of the final water purifier neat and beautiful, a base is used, a control device of the water purifier, a pipeline of running water, etc. are all installed on the base 200, in this embodiment, a waterway plate is installed in the base 200, and the pipeline is implanted in the waterway plate, so that water holes are formed at corresponding positions on the filter element installation seat 210, and as shown in fig. 4, two water holes, namely a water inlet hole 213 and a water outlet hole 212, are formed on the filter element installation seat 210.
In the cartridge module 100, the head 111 of the housing 210 is a mounting interface for the cartridge mount 210 on the base 200, as shown in fig. 5 and 6. In the head 111 of the mold 210, an annular water inlet 113 is arranged outside, water entering the filter element module 100 from the annular water inlet 113 flows upwards along the filter element 120 and the inner wall of the mold 110, enters the filter element 120 from the top of the filter element 120, is absorbed or filtered by the filter element 120, and finally produced purified water is discharged from a water outlet 112 in the center of the annular water inlet 113 and enters a water channel in the base 200 from a water outlet 212 in the middle of the filter element mounting seat 210.
In this embodiment, a water control mechanism is disposed in the annular water inlet 113 and the water outlet 112 at the center thereof, and when the filter element module 100 is mounted on the base 200, the water control mechanism is separated from the annular water inlet 113 and the water outlet 112 through interaction between the head 111 of the mold shell 110 and the filter element mounting seat 210, and at this time, if there is water pressure in a pipe implanted in the base 200, the water enters the annular water tank in the filter element mounting seat 210 opposite to the annular water inlet 113 through the water inlet 213 in the filter element mounting seat 210, then enters the filter element module 100 through the annular water inlet, flows out from the water outlet 112 after being filtered, and enters the waterway in the base 200 from the water outlet 112 in the middle of the filter element mounting seat 210. When the filter element module 100 is separated from the base 200, the head 111 of the filter element module 110 is not contacted with the filter element mounting seat 210, and the water control mechanism is plugged into the annular water inlet 113 and the water outlet 112, so that the annular water inlet 113 and the water outlet 112 are both plugged, and water cannot leak.
As for the water control mechanism, there are many alternatives, such as using angle control switches, which control the opening of the annular water inlet 113 and the water outlet 112 only when the filter cartridge module 100 is mounted on the base 200, and control the blocking of the annular water inlet 113 and the water outlet 112 when the filter cartridge module 100 is detached from the base 200.
In this embodiment, the first water plug 115 and the second water plug 114 are respectively disposed in the annular water inlet 113 and the water outlet 112, in this embodiment, the first water plug 115 and the second water plug 114 are respectively disposed according to the shapes of the annular water inlet 113 and the water outlet 112, and in the filter element mounting seat 210 on the base 200, two bosses are disposed, that is, when the filter element membrane module 100 is mounted in the filter element mounting seat 210 on the base 200, the first boss 215 and the second boss 214 of the first water plug 115 and the second water plug 114 are propped up.
The specific shape of the first water plug 115 is shown in fig. 7 and 8, and includes an annular water plug 115-1 having a shape corresponding to that of the annular water inlet 113, and support legs 115-2 are provided under the annular water plug 115-1, and when the cartridge membrane module 100 is mounted in the cartridge mounting seat 210 on the base 200, the support legs 116-2 are supported by the first boss 215, so that the annular water plug 115-1 can be ejected out of the annular water inlet 113, as shown in fig. 5. When the core module 100 is removed from the filter element mounting seat 210, the annular water plug 115-1 is pressed downwards due to a certain water pressure in the filter element module 100, so that the annular water plug 115-1 is pressed into the annular water inlet 113 to block the annular water inlet 113, and water in the filter element module 100 is prevented from flowing out of the annular water inlet 113.
Fig. 9 shows a specific shape of the second water plug 114 used in this embodiment, since the filter element 120 generally adopts a middle circular water outlet to discharge water, so the head 111 of the mold shell 110 is also provided with a circular water outlet 112 in the center, and a water outlet bottle shin is arranged at the position where the water outlet 112 of the head 111 of the mold shell 110 is connected with the water outlet of the filter element 120, so the second water plug 114 is plugged in the water outlet bottle shin hole by adopting a plug head 114-1, and elastic substances can be arranged outside the plug head 114-1, and a strut is utilized to connect the dovetail plug tail 114-2 at the plug head 114-1. As with the first plug 115 in the annular inlet 113, when the cartridge membrane module 100 is installed in the cartridge mount 210 on the base 200, the dovetail plug tail 114-2 is supported by the second boss 214, so that the resilient plug head 114-1 can be ejected out of the bottle shank, and the purified water filtered by the cartridge 120 can flow out of the bottle shank into the outlet 112 in the middle of the head 111 of the die shell 110, and then enter the outlet 214 in the cartridge mount 210 through the outlet 112 to flow into the pipe in the base 200. When the filter cartridge module 100 needs to be removed from the filter cartridge mounting base 210, the lower surface of the dovetail-shaped plug tail 114-2 is not supported, and the annular water plug head 114-1 is pressed into the shin hole of the water bottle due to a certain water pressure in the filter cartridge module 100, so that water in the filter cartridge module 100 cannot flow out from the water outlet.
