[0030] like Figures 1 to 3 As shown:

[0031] The water purifier for easy replacement of the filter screen comprises a sliding rod 110, and a fixed shell 100 is detachably connected to both ends of the sliding rod 110 by screws, and the two fixed shells 100 are symmetrically arranged, and the outer sides of the two fixed shells 100 are both threadedly connected with a connecting sleeve 120, and the sliding rod 110 is sleeved with two mutually symmetrical filter screen sleeves 200 for replacing the filter screen, and the filter screen sleeve 200 at the lower end is located between the two fixed shells 100, and the filter screen 150 is clamped on the filter screen sleeve 200 at the lower end, and the filter screen sleeve 200 at the upper end is sleeved on the fixed shell 100 at the upper end;

[0032] When the water purifier is in normal use, one filter sleeve 200 is sleeved on the fixed shell 100 at the upper end, and the other filter sleeve 200 is arranged between the two fixed shells 100. The filter 150 is clamped on the filter sleeve 200 arranged between the two fixed shells 100. The water to be purified reaches the other end from one end through the filter 150 to complete the purification work; when the filter 150 needs to be replaced, the filter sleeve 200 at the upper end is opened, and the new filter 150 is clamped inside the filter sleeve 200 at the upper end, and the filter sleeve 200 at the upper end is closed at the same time, and the filter sleeve 200 at the upper end is pushed toward the center along the sliding rod 110, so that the two filter sleeves 200 are on the same horizontal plane and fit each other, and the filter sleeve 200 located on the outer side of the two fixed shells 100 is rotated with the sliding rod 110 as the axis. , so that the filter ferrule 200 with the new filter 150 is inserted between the two fixed shells 100, and at the same time, the filter ferrule 200 of the filter 150 to be replaced at the initial position is pushed out from the other side, the filter ferrule 200 of the filter 150 to be replaced is opened, the old filter 150 is taken out for replacement or cleaning, and the replaced filter ferrule 200 is sleeved on the fixed shell 100 at the lower end, thereby quickly completing the replacement of the filter 150 under the premise that the water purification system is not shut down; secondly, during the pushing process, the two filter ferrules 200 fit each other to block the pipeline, which can avoid leakage; at the same time, through the recycling of the two filter ferrules 200, the cost and operation complexity of the water purifier can be reduced at the same time, and the unused filter ferrule 200 can be sleeved on the fixed shell 100 to reduce the actual volume occupied by the water purifier.

[0033] like Figure 4 and Figure 5 As shown:

[0034] The filter sleeve 200 includes a first filter sleeve 210, and a second filter sleeve 220 is detachably mounted on the first filter sleeve 210. The first filter sleeve 210 and the second filter sleeve 220 are both provided with filter slots 201 on their inner sides. The filter 150 is clamped between the two filter slots 201 in the middle. The first filter sleeve 210 and the second filter sleeve 220 are both mounted on the sliding rod 110.

[0035] When the filter screen 150 located in the middle of the device needs to be replaced, the first filter screen sleeve 210 and the second filter screen sleeve 220 located on the upper filter screen sleeve 200 are disassembled from the connection with the upper fixed shell 100, and are rotated in opposite directions along the sliding rod 110 respectively, and the new filter screen 150 is clamped between the two filter screen slots 201, and the first filter screen sleeve 210 and the second filter screen sleeve 220 are reconnected, and the first filter screen sleeve 210 is pushed downward to drive the second filter screen sleeve 220 and the filter screen 150 to move to the middle part of the water purifier and insert them between the two fixed shells 100, and the filter screen sleeve 200 originally in the middle is pushed out, so as to realize the movement of the upper filter screen sleeve 200 to the middle of the device. In the middle part, replace the original old filter sleeve 200; disassemble the old first filter sleeve 210 and the second filter sleeve 220 that are pushed out from the connection, remove the old filter 150, and push the old first filter sleeve 210 and the second filter sleeve 220 toward the edge of the water purifier, and rotate the first filter sleeve 210 and the second filter sleeve 220 in opposite directions along the axial direction of the sliding rod 110, so that they are buckled and sleeved on the fixed shell 100 at the lower end, reconnect the old first filter sleeve 210 and the second filter sleeve 220, complete the replacement of the filter 150, and at the same time, the old filter sleeve is buckled on the fixed shell 100, which serves as a spare replacement while completing the storage.

[0036] like Figure 6 As shown:

[0037] Both ends of the sliding rod 110 are detachably connected to a fixing flange 111 by screws, and the fixing flange 111 is detachably connected to the fixing shell 100 by screws;

[0038] When the filter 150 is replaced, the two symmetrically arranged first filter covers 210 and the two second filter covers 220 can be adjusted to the same plane by rotating on the sliding rod 110, so that the first filter cover 210 and the second filter cover 220 to be replaced can be inserted between the two fixed shells 100 to complete the replacement work; at the same time, when it is necessary to install or remove the first filter cover 210 and the second filter cover 220, the fixing flange 111 close to the first filter cover 210 or the second filter cover 220 can be removed, thereby completing the installation or removal of the first filter cover 210 or the second filter cover 220.

[0039] like Figures 7 to 12 As shown:

[0040] The first filter screen sleeve 210 is provided with a first rotating buckle 211, and the second filter screen sleeve 220 is provided with a second rotating buckle 221. The first rotating buckle 211 and the second rotating buckle 221 are both mounted on the sliding rod 110, and the two first rotating buckles 211 are both located between the two second rotating buckles 221; the first rotating buckle 211 is located on the upper side of the first filter screen sleeve 210, and the second rotating buckle 221 is located on the upper side of the middle part of the second filter screen sleeve 220. The thickness of the first rotating buckle 211 and the second rotating buckle are both one-fourth of the first filter screen sleeve 210 and the second filter screen sleeve 220, so that when the lower end of the first rotating buckle 211 and the upper end of the second rotating buckle 221 are fitted, the two symmetrically arranged first filter screen sleeves 210 and the two second filter screen sleeves 220 can rotate between the two fixed shells 100 at the same time.

[0041] Further:

[0042] The sides of the first rotating buckle 211 and the second rotating buckle 221 are both arc-shaped; when the first filter cover 210 and the second filter cover 220 need to rotate along the sliding axis respectively, it can avoid the first filter cover 210 and the second filter cover 220 interfering with each other and causing failure to rotate.

[0043] Further:

[0044] Arc-shaped oil seal grooves 202 are provided on both sides of the first filter sleeve 210 and the second filter sleeve 220, and an oil seal pipeline 101 corresponding to the oil seal groove 202 is provided on the outer side of the inner end of the fixed shell 100; when the first filter sleeve 210 and the second filter sleeve 220 of the newly replaced filter 150 are inserted between the two fixed shells 110, sealing oil can be injected into the oil seal groove 202 through the oil seal pipeline 101 to avoid leakage between the first filter sleeve 210, the second filter sleeve 220 and the two fixed shells 100.

[0045] Further:

[0046] The inner side of the oil seal groove 202 is provided with an oil-resistant rubber sealing layer 203; thus, when the first filter cover 210 and the second filter cover 220 need to be inserted between the two fixed shells 100, the friction between the first filter cover 210, the second filter cover 220 and the two fixed shells 100 is increased, so that the first filter cover 210 and the second filter cover 220 will not slip out from between the two fixed shells 100, thereby causing leakage.

[0047] Further:

[0048] The outer circumferential surfaces of the first filter cover 210 and the second filter cover 220 are both provided with inclined pushing fitting surfaces 212; when the first filter cover 210 and the second filter cover 220 of the newly replaced filter 150 are inserted between the two fixed shells 110, the pushing fitting surfaces 212 fit together, so that the first filter cover 210 and the second filter cover 220 can completely cover the water inlet on the fixed shell 100 during the pushing process, thereby playing the role of closing the water inlet pipe of the water purifier, so that the water purifier will not leak during the replacement process.

[0049] like Fig.13 As shown:

[0050] The first filter sleeve 210 and the second filter sleeve 220 are both provided with a connecting block 204, and a screw is inserted between the two connecting blocks 204 on the same filter sleeve 200, and a nut 130 is threadedly connected to the screw; when the first filter sleeve 210 and the second filter sleeve 220 are installed with the filter 150 or are sleeved on the fixed shell 100, the first filter sleeve 210 and the second filter sleeve 220 can be fixed together by the screw and the nut 130; at the same time, through the connecting block 204 protruding from the outside of the fixed shell 100, the first filter sleeve 210 and the second filter sleeve 220 can be pushed quickly and labor-savingly to accurately reach the predetermined position.

[0051] like Fig.14 As shown:

[0052] A mesh sleeve groove 102 is provided on the outside of the fixed shell 100, and the first filter sleeve 210 and the second filter sleeve 220 at the upper end are sleeved in the mesh sleeve groove 102 at the upper end; when the first filter sleeve 210 and the second filter sleeve 220 are replaced, they can be nested inside the mesh sleeve groove 102, thereby preventing the first filter sleeve 210 and the second filter sleeve 220 sleeved on the outside of the fixed shell 100 from sliding up and down.
