DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] The utility model discloses an activated carbon filter sheet, such as Figure 1-5 As shown, it includes two fixed frames 1, two connecting rods 2 are fixedly installed on one side of the outer surface of the two fixed frames 1, and two connecting sleeves 3 are fixedly installed on the other side of the outer surface of the two fixed frames 1. When the two connecting rods 2 are inserted into the two connecting sleeves 3, the two fixed frames 1 can be assembled and spliced.

[0023] A pull rod 201 is movably installed inside the connecting rod 2, and a baffle 202 is fixedly installed on the bottom surface of the pull rod 201. When the user pulls the pull rod 201, the baffle 202 can be driven to rise. A pull plate is fixedly installed on one end of the pull rod 201 away from the baffle 202.

[0024] A spring 203 is fixedly mounted on the top surface of the baffle 202 , and the spring 203 is fixedly connected to the inner top surface of the connecting rod 2 . When the user pulls the pull rod 201 to raise the baffle 202 , the baffle 202 will squeeze the spring 203 .

[0025] The bottom surface of the baffle 202 is movably connected to two driving rods 204, and the outer surface of the connecting rod 2 is movably installed with two fixed plates 205, and the two driving rods 204 are movably connected to the two fixed plates 205 respectively. When the baffle 202 rises, the two driving rods 204 can drive the two fixed plates 205 to extend and retract. When the baffle 202 descends, the two driving rods 204 can push the two fixed plates 205 to expand.

[0026] A limiting ring 301 is fixedly installed inside the connecting sleeve 3. When the connecting rod 2 is inserted into the connecting sleeve 3, the two unfolded fixing plates 205 will contact the limiting ring 301. As the connecting rod 2 is continuously inserted, the fixing plates 205 will shrink. When the fixing plates 205 shrink, the two driving rods 204 can push the baffle plate 202 to rise and squeeze the spring 203. After the fixing plate 205 passes through the limiting ring 301, the baffle plate 202 can be pushed down under the rebound force of the spring 203. When the baffle plate 202 falls, the two driving rods 204 can push the two fixing plates 205 to unfold, so that the connecting rod 2 cannot be pulled out of the connecting sleeve 3, and the two fixing frames 1 can be connected.

[0027] The outer surface of the connecting rod 2 is provided with threads, and one side of the outer surface of the connecting rod 2 with threads is threadedly connected with a fixing nut 206. When the connecting rod 2 is inserted into the connecting sleeve 3, the fixing nut 206 can be rotated to make the connection between the connecting rod 2 and the connecting sleeve 3 tighter.

[0028] When the two fixing frames 1 need to be separated, the fixing nut 206 is first rotated to make it rise, and then the user pulls the pull rod 201 to drive the baffle 202 to rise and squeeze the spring 203 to shrink the two fixing plates 205, so that the connecting rod 2 can be pulled out of the connecting sleeve 3.

[0029] An activated carbon filter layer 103 for filtering is provided between the two fixed frames 1, two first filter screens 101 are fixedly installed inside the two fixed frames 1, and two filter cottons 102 are fixedly installed between the two first filter screens 101, which are made of adsorption resin material. The two filter cottons 102 are fixedly connected to the activated carbon filter layer 103, and the activated carbon filter layer 103 is located between the two filter cottons 102, and the activated carbon filter layer 103 can adsorb harmful substances in the medium.

[0030] Through the detachable connection between the two fixing frames 1, the second filter screen 104, the filter cotton 102 or the activated carbon filter layer 103 can be disassembled, so that when the activated carbon filter is replaced, the still usable part can be disassembled for subsequent recycling and reuse to reduce the waste of resources.

[0031] A placing frame 105 is fixedly installed on one side of the fixing frame 1, a second filter screen 104 is arranged on one side of the placing frame 105, and two fixing blocks 106 are movably installed on the top surface of the placing frame 105, and the two fixing blocks 106 can rotate.

[0032] Two magnets 107 are fixedly installed on the top surface of the placement frame 105, and two iron sheets 108 are fixedly installed on the bottom surface of the second filter screen 104. Fixing holes 109 are opened on both sides of the second filter screen 104. The second filter screen 104 is placed on one side of the placement frame 105, and the two fixing blocks 106 are inserted into the two fixing holes 109 and rotated. The magnet 107 can absorb the iron sheet 108, and then the second filter screen 104 can be installed, so that the second filter screen 104 can be replaced.

[0033] The working principle of the utility model is as follows: when the connecting rod 2 is inserted into the connecting sleeve 3, the two unfolded fixing plates 205 will contact the limiting ring 301. As the connecting rod 2 is continuously inserted, the fixing plates 205 will shrink. When the fixing plates 205 shrink, the two driving rods 204 can push the baffle plate 202 to rise and squeeze the spring 203. After the fixing plates 205 pass through the limiting ring 301, the baffle plate 202 can be pushed down under the rebound force of the spring 203. When the baffle plate 202 falls, the two driving rods 204 can push the two fixing plates 205 to unfold, so that the connecting rod 2 cannot be pulled out of the connecting sleeve 3, so that the two fixing frames 1 can be connected. Then, the fixing nut 206 can be rotated to make it descend and contact with the top surface of the connecting sleeve 3, so that the two fixing frames 1 can be connected. When the activated carbon filter needs to be replaced, the fixing nut 206 can be rotated to make it rise, and then the user pulls the pull rod 201 to drive the baffle 202 to rise and squeeze the spring 203 to shrink the two fixing plates 205, so that the connecting rod 2 can be pulled out of the connecting sleeve 3, so as to separate the two fixing frames 1, so that the first filter screen 101, the filter cotton 102 or the activated carbon filter layer 103 between the two fixing frames 1 can be disassembled, so that the still usable part can be removed for subsequent recycling and reuse.
