Examples

As shown in fig. 1 to 3, a multiple purification cartridge for air purification is installed between an air inlet pipe and an air outlet pipe of a fresh air machine to purify external air entering the fresh air machine, so that the fresh air machine can output fresh air. The filter element comprises a filter core box 1 and a plurality of filter components 2 positioned in the filter core box 1, and the filter core box 1 is respectively connected with an air inlet pipe and an air outlet pipe of the fresh air fan through fixing parts such as bolts. The filter element 2 is a primary filter screen for coarse filtration, a high-efficiency filter screen for high-efficiency filtration, an activated carbon filter screen for odor adsorption and a cold catalyst filter screen for harmful gas decomposition in sequence from left to right. Wherein, the primary filter screen is close to the air inlet pipe of new fan, and the cold catalyst filter screen is close to the air outlet pipe of new fan. In this embodiment, the large granule impurity of metal filter screen preparation in order filtered air is chooseed for use to the primary filter screen, the filtration of the follow-up filter screen of dust impurity influence that avoids having in the air, and the metal filter screen washs conveniently, and the filter screen is difficult to impairedly, has improved the life of the primary filter screen, and the HEPA filter screen that can be to the small particulate matter filteration below the 0.3 micron of diameter in the air is chooseed for use to high-efficient filter screen to improve the filtration degree to small impurity in the air.

Furthermore, the filter core box 1 is a U-shaped box body 11 and a box cover 12 which only have left and right side walls and a bottom plate, and the box body 11 and the box cover 12 are fixed through bolts. Be equipped with a plurality of outstanding fixed subassemblies 3 in the box body 11, every fixed subassembly 3 includes two U-shaped plates 31 and sets up the vertical spring 32 between U-shaped plate 31, and U-shaped plate 31 passes through mounting such as bolts to be fixed with the lateral wall and the bottom plate of box body 11 respectively, and spring 32 fixes on the bottom plate of box body 11. And the distance between the adjacent U-shaped plates 31 is greater than the width of the filter element 2 so that the filter element 2 can be placed in the fixing assemblies 3, the number of the fixing assemblies 3 corresponding to the number of the filter elements 2. It is worth mentioning that the filtering components 2 comprise a peripheral filtering frame and a filtering net fixed on the inner wall of the filtering frame, each filtering component 2 can be conveniently and stably placed in the fixing component 3 through the filtering frame, and after the filtering component 2 is placed, the spring 32 is compressed at the bottom of the filtering frame.

Furthermore, a plurality of sockets 4 are arranged on two side walls of the box body 11, and the sockets 4 are located on the side wall of the box body 11 corresponding to each fixing component 3. The upper wall department of socket 4 is equipped with spout 5, is equipped with in the socket 4 with spout 5 assorted T type slider 6, slider 6 including being located the inside vertical section 61 of spout 5 and rather than integrated into one piece be located the horizontal segment 62 of socket 4, slides in spout 5 through vertical section 61, can be so that horizontal segment 62 horizontal migration in socket 4.

Furthermore, the left side wall and the right side wall of the filter frame are provided with grooves 7 matched with the ports of the sliding block 6, after the filter frame is placed in the fixing component 3, the sliding block 6 is moved, so that the transverse section 62 of the sliding block can be inserted into the grooves 7, and the position of the filter frame in the fixing component 3 can be fixed. Specifically, when the vertical section 61 is located on the wall of the chute 5 near the inner wall of the box body 11, the part of the horizontal section 62 located inside the box body 11 is inserted into the groove 7 of the filter frame, as shown in fig. 4 (a); when the vertical section 61 is located on the wall of the chute 5 near the outer wall of the box body 11, the part of the horizontal section 62 located inside the box body 11 is completely moved out of the groove 7 of the filter frame, as shown in fig. 4 (b). It should be noted that, no matter where the vertical section 61 is located on the sliding slot 5, a part of the horizontal section 62 is always exposed outside the box 11, so that the user can hold the vertical section 61 to slide the sliding block 6.

Further, in order to ensure the tightness between the box body 11 and the sliding block 6, the inner wall of the socket 4 is further provided with a rubber sealing strip 63.

Further, in order to facilitate the replacement of a single filter element 2 in the box body 11, an opening 121 is further provided at the box cover 12 corresponding to the top of each fixing component 3, and the filter element 2 in the box body 11 can be exposed through the opening 121 without opening the box cover 12. The opening 121 is covered by a filter element cover 122 hinged with the box cover 12, and the inner wall of the filter element cover 122 is provided with a raised sealing ring 123 matched with the size of the opening 121. The filter element cover 122 is located at the hinged tail end of the box cover 12 and is movably connected with the side wall of the box body 11 through a magic tape. After the filter element cover 122 is closed, the outer wall of the sealing ring 123 is respectively attached to the inner wall of the opening 121, so as to avoid the air leakage inside the box body 11 when the filter element works. The outer wall of the filter element cover 122 is provided with a handle, which is convenient for a user to open the filter element cover 122 through the handle, as shown in fig. 5-6.

Specifically, when a single filter element 2 needs to be replaced, a user opens the filter element cover 122 through the handle to expose the opening 121 on the box cover 12, and then moves the slider 6 on the side wall of the box body 11 in a direction away from the side wall of the box body 11 until the transverse section 62 is separated from the filter frame groove 7 and cannot slide, at this time, because the slider 6 cannot fix the filter frame, after the filter frame is not held by the top filter element cover 122 and the slider 6, the pressure of the filter frame on the spring 32 is reduced, the spring 32 gradually recovers to the original length, so that the filter frame is sprung upwards, that is, the top of the filter frame extends out of the opening 121, and then the user can take out the filter frame to replace the filter element 2. When reinstalling the filter frame, insert fixed subassembly 3 from opening 121 with the filter frame in, along with the extrusion of bottom spring 32, the filter frame can be placed in box body 11 completely, closes filter element lid 122 this moment to with slider 6 to the direction removal that is close to box body 11 lateral wall, until horizontal section 62 inserts and can't slide in the filter frame recess 7, so can accomplish the fixed of whole filter frame. If all the filter components 2 in the filter element box 1 need to be replaced, a user only needs to disassemble the box cover 12 from the filter element box 1 body, and all the filter components 2 in the filter element box 1 can be exposed, so that the filter components can be replaced.

The utility model discloses the filter core that sets up, in high-efficient filterable, convenience of customers changes the filter core, has improved the convenience of filter core when new fan, and the user need not to use too much outside appurtenance when changing, can convenient and fast change filter part 2.
