In the following description, the water inlet in the center of the cartridge 100 is referred to as the duct 131.
As shown in fig. 5 and 6, the filter cartridge 100 of the water purifier in this embodiment is an RO reverse osmosis membrane filter cartridge, which includes a die case 120 and a filter 110 installed in the die case 120, and the filter 110 is an RO reverse osmosis membrane, and in this embodiment, the main feature is that the filter cartridge interface 130 installed on the water channel plate 200 is provided at the bottom of the die case 120, and it is paired with the corresponding water channel plate interface 210 in the water channel plate 200 as shown in fig. 4, and as shown in fig. 7 and 8, a fixing mechanism for installing the filter cartridge 100 on the water channel plate 200 is provided outside the filter cartridge interface 130, by which the filter cartridge 100 can be directly installed on the water channel plate interface 210 prepared for it by the water channel plate 200. As shown in fig. 8, the fixing mechanism includes pins 132 symmetrically disposed at both sides of the channel 131, and since the filter element of this embodiment is an RO reverse osmosis membrane filter element, there are three channels 131 communicating with the water channels in the water channel plate in the filter element interface 130, three channels are arranged in a row, the middle is a water outlet channel through which purified water after filtration, and both sides are a water inlet channel and a wastewater outlet channel, respectively, where the pins 132 symmetrically disposed at both sides of the channel 131 represent both sides perpendicular to the directions of the three channels arranged in a row. Pin 132 includes a pin body 1322 and a pin head 1321, pin head 1321 is disposed in a pipe type slide guide 134 communicating with port 131, when pin head 1321 is disposed in pipe type slide guide 134, if booster pump 300 is operated or for other reasons when cartridge 100 is mounted on waterway plate 200, water pressure in waterway plate 200 is large and enters pipe type slide guide 134, pin head 1321 and pipe type slide guide 134 form a hydraulic cylinder, pipe type slide guide 134 is a cylinder, pin head 1321 is a piston, and pin head 1321 is moved outwards under the condition of relatively large water pressure, so that latches 132 on both sides are moved outwards. The key 1322 is disposed in a key slide 1325, and when the head 1321 is to be moved outwardly, the key 1322 also slides outwardly in the key slide 1325. A bolt 1323 is arranged in the bolt 1322, the bolt 1323 extends out of the bolt 1322 by the elasticity of a bolt spring 1324, a gap 1326 is arranged on the wall of a bolt slideway 1325, and when the bolt 132 slides outwards to fix the filter element 100, the bolt 1323 extends out of the bolt 1322 and is locked in the gap 1326; that is, as pin 132 slides outwardly, when pin 1323 extends from body 1322 to snap into notch 1326, it is restricted from sliding further outwardly, and cartridge 100 is now secured to waterway plate 200, and pin 132 is no longer moved, as cartridge 100 of this embodiment is now secured to waterway plate 200 by pin 132. During the operation of the water purifier, the water pressure is relatively high, the pin 132 will not reset naturally, and when the booster pump 300 is not pressurized and the water pressure in the water path plate 200 is low or disappears, the pin 132 will not slide because the pin 1323 extends out of the pin body 1322 and is blocked in the notch 1326, and the filter element 100 is stably mounted on the water path plate 200. In order to prevent water from leaking from this place, in this embodiment, a set of sealing rings 1327 are provided on the plug 1321, so that no water leaks out, regardless of the water pressure in the waterway board, the pipe type sliding guide 134 and the plug 1321 are tightly matched.
In order to reset the peg 132 when the cartridge 100 needs to be removed, a mechanism for pushing the peg 1323 is further provided at the cartridge interface 130, when the cartridge 100 needs to be removed, the peg 1323 is pushed, so that the peg 1323 is pushed back into the peg 132 against the elastic force of the peg spring 1324, the mechanism comprises an upper peg 1352, a lower peg 1351 and a protrusion 1354 provided below the notch 1326, the peg 135 comprises an upper peg 1352, a lower peg 1351 and a protrusion 1354, the peg spring 1353 is provided around the upper peg 1352, the lower peg 1351 protrudes from the bottom shell 121 under the action of the peg spring 1353, at this time, the top of the upper peg 1352 does not push against the peg 1323, when a pressure is applied from the top of the lower peg 1351, at this time, the top of the upper peg 1352 pushes the peg 1323, so that the peg 1323 is retracted into the peg 132, when the cartridge 100 needs to be removed, so that the cartridge 100 slides downwards, the top of the lower peg 1351 will collide with the top plate 200, and the water channel 132 is pushed back up against the top plate 212, and the water channel 132.
In addition, the fixing mechanism further comprises two return springs 133 disposed at two sides of the hole 131, and the two return springs 133 pull the pin 132 back from two sides of the pin 1322.
In this embodiment, the elastic force of the two return springs 133 pulling the bolt inward may be set to 2 kg, and when the filter cartridge 100 is mounted on the waterway board 200, the booster pump 300 is operated, in the hydraulic cylinder formed by the pipe type sliding guide 134, a larger pulling force is applied to the bolt head 1321 than the return springs 133, and according to the test, at this time, the water pressure reaches 5 kg to the outward pressure of the bolt head 1321, so that the bolt 132 is pushed outward until the bolt 1323 is inserted into the notch 1326. When maintenance of the water purifier is required, the booster pump 300 stops boosting, the water pressure in the waterway plate 200 is reduced until the same atmospheric pressure as the outside is reached, at this time, the outward pressure of the plug head 1321 is zero, at this time, a force is applied to the waterway plate 200 from the filter cartridge 100, the plug pins 1323 are pushed back into the plug pins 132 by the plug pins 135, the plug pins 132 on both sides are pulled back by the return springs 133, and at this time, the filter cartridge 100 can be separated from the waterway plate 200 for maintenance.
