Referring to fig. 2, two first side shell plates 112 and two second side shell plates 113 are in a staggered sealing connection mode, and the top and the bottom of the two first side shell plates 112 and the two second side shell plates 113 are respectively mounted in the top shell 111 and the bottom shell 114 in an inserting mode, meanwhile, sealing fixation is realized between the top shell 111, the bottom shell 114 and the two first side shell plates 112 and the two second side shell plates 113 by means of mounting rings 115, (the mounting rings 115 can be connected by bolts, not shown in the drawing), so that the shell of the device body 1 can be integrally dismounted, and further the dismounting operation and the subsequent mounting process of the filter element group 13 are greatly facilitated.
The primary filter core 131 is composed of two first filter areas 21 and two replacement filter areas 22, the two first filter areas 21 and the two replacement filter areas 22 are installed in a staggered mode, the bottom of the primary filter core 131 penetrates through the installation holes to extend out of the surface of the bottom shell 114, one end of the primary filter core 131 extending out of the bottom shell 114 is fixedly provided with an extension disc 23 through bolts, and the surface of the extension disc 23 is provided with a lock catch group 24.

The primary filter element 131 is movably mounted in the device body 1, therefore, the primary filter element 131 can be supported in an auxiliary manner through the side rod assembly 3, the specific structure of the side rod assembly 3 is disclosed below, the side rod assembly 3 comprises inner supporting rods 32 mounted on the surface of the primary filter element 131, the inner supporting rods 32 are provided with four inner supporting rods, one ends of the four inner supporting rods 32, far away from the primary filter element 131, are attached to the surface of the secondary filter element 132, a plurality of outer side columns 31 are fixedly mounted on the inner walls of the two second side shell plates 113, two top supporting rods 33 are fixedly mounted on the bottoms of the upper ends of the whipping pieces 14, the tops of the primary filter element 131 are rotationally clamped in the outer side top supporting rods 33, and the tops of the secondary filter element 132 are fixedly clamped in the inner side top supporting rods 33.
As can be seen from fig. 3 and 7, inside the apparatus body 1, each filter core is in nested distribution to realize multi-layer filtration purification on air, where the primary filter core 131 is disposed at a position close to the air inlet 12 and is used for intercepting impurities with larger particles, such as dust and hair, the middle-effect filter core 132 is sleeved at the middle part of the primary filter core 131, the filtration precision is higher than that of the primary filter core 131, the particles with smaller size can be further captured, the inner-layer filter core 133 is located at the middle part of the middle-effect filter core 132, the finer filtration capability is provided, and the filtration pore size on the surface of the inner-layer filter core 133 is in a decreasing trend from the primary filter core 131 to the middle-effect filter core 132, so that when the air sequentially passes through each filter core, the impurities and the pollutants with different particle diameters can be gradually removed, thereby ensuring that the air after multi-layer filtration reaches higher purification standards, and effectively improving the air quality.
As shown in fig. 8 and 9, when the primary filter element 131 is mounted, the bottom of the primary filter element 131 is aligned with the mounting hole formed in the middle of the bottom shell 114 in advance, and then the primary filter element 131 is mounted by passing through the mounting hole, and then connecting the extension plate 23 positioned in the bottom shell 114 with the bottom of the primary filter element 131 by using bolts, wherein the fluted disc 241 and the driving gear 242 need to be in a meshed connection state when the extension plate 23 is mounted;
Referring to fig. 4, the inside of the primary filter element 131 is divided into four areas including two first filter areas 21 and two replacement filter areas 22, and these four areas are in a staggered form, after the primary filter element 131 is installed, the two first filter areas 21 are located close to the two first side shell plates 112, which means that they are close to the air inlet 12, and at the same time, the two replacement filter areas 22 are located close to the second side shell plates 113, as shown in fig. 10, when the apparatus body 1 is continuously operated for a period of time, the two first filter areas 21 are relatively blocked, the driving gear 242 is rotated, and due to the meshing connection relationship between the fluted disc 241 and the driving gear 242, the rotation of the driving gear 242 drives the fluted disc 241 to rotate together with the primary filter element 131, and then drives the extension disc 23 connected with the fluted disc 241, so that, as can be seen from fig. 5, the replacement filter areas 22 originally located close to the second side shell plates 113 are rotated to the positions of the previous first filter areas 21, so that the replacement operation of the filter areas can be realized, and the filter element can be balanced by the filter element, and the filter element can have the efficiency of the whole filter element, and the filter element can be improved, and the filter life of the filter element can be balanced, and the filter device can be used for the filter element 131.
Referring to fig. 6, an inner stay bar 32 is installed at one side of the primary filter core 131 near the middle-effect filter core 132, when the equipment starts the rotation procedure of the primary filter core 131, the inner stay bar 32 will generate relative motion with the surface of the middle-effect filter core 132, thereby playing a role in scraping and cleaning the surface of the middle-effect filter core 132, meanwhile, a plurality of outer side columns 31 are installed at the inner walls of the two second side shell plates 113, when the primary filter core 131 rotates, the surface of the primary filter core 131 will contact and rub with the outer side columns 31, and the contact can effectively clean the surface of the primary filter core 131, so that part of dust and impurities adsorbed on the surface of the primary filter core 131 can be removed;
It should be noted that, in the process of cleaning the surface of the primary filter element 131, since the outer side posts 31 are horizontally installed, they have unique cleaning advantages for the long-strip-shaped miscellaneous dust such as hair, and when the miscellaneous dust such as hair contacts the outer side posts 31, the miscellaneous dust will be hooked and will not easily fall into the bottom shell 114 of the device, thus greatly reducing the possibility of accumulation of the impurity such as hair in the bottom shell 114, thereby avoiding the occurrence of the situation that the normal rotation of the primary filter element 131 is affected due to the problem of hair winding, and further improving the reliability and stability of the device.
In the running process of the equipment body 1, the outer side columns 31 can effectively support and fix the primary filter core 131 which is movably mounted, when the equipment is subjected to external vibration or shake caused by internal airflow impact, the primary filter core 131 can keep relatively stable positions and postures by virtue of contact with the outer side columns 31, so that the stability of the equipment in running is improved, the problems of poor filtering effect and the like possibly caused by displacement or shake are reduced, and the reliable running and efficient working of the whole air purifying equipment are ensured.
In order to further improve the cleaning effect on the primary filter element 131 and the secondary filter element 132, side hook grooves 4 are formed in one end surface of the four inner stay bars 32 close to the secondary filter element 132 and one side surface of the plurality of outer side posts 31 close to the primary filter element 131.
The improvement is that when the inner stay bar 32 and the outer side column 31 are contacted with the corresponding filter element in the running process of the device, the side hook groove 4 can hook the impurities which are relatively stubborn, tiny and difficult to remove by the conventional cleaning mode on the surface of the filter element by virtue of the unique shape and structure, so that the cleaning effect is improved.
The working principle of the inner filter core 133 is mainly adsorption cleaning, and impurities adsorbed in the operation process are relatively less, and impurities are not easily accumulated on the surface due to the adsorption characteristic of the inner filter core 133, so that the inner filter core 133 does not need to perform special cleaning operations as frequently as the primary filter core 131 and the middle-effect filter core 132 from the perspective of the overall operation efficiency and the cost of maintenance equipment, and only needs to perform proper inspection and maintenance when the equipment is subjected to regular overall maintenance.
To be able to further determine the rotational position of the first filter zone 21 and the replacement filter zone 22, the surfaces of the toothed disc 241 and the bottom shell 114 are provided with indicators 5.
The improvement lies in that, referring to fig. 11, indicators 5 are arranged on the surfaces of the fluted disc 241 and the bottom shell 114, and the rotation condition of the first filtering area 21 and the replacement filtering area 22 in the primary filter core 131 can be clearly known by observing the relative position change of the indicators 5, so that a user can better grasp the running state of the device, maintain and adjust in time, and ensure that the filtering function of the device can be effectively exerted.
Wherein the dotted arrows in fig. 4, 5 and 7 indicate the direction of air intake.
In summary, the working principle of the scheme is that in the equipment body 1, each filter core is in nested distribution to realize multi-layer filtration and purification of air, wherein the primary filter core 131 is arranged at a position close to the air inlet 12 and is used for intercepting impurities with larger particles, such as dust, hair and the like, the middle-effect filter core 132 is sleeved at the middle part of the primary filter core 131, the filtration precision is higher than that of the primary filter core 131, the particles with smaller size can be further captured, the inner-layer filter core 133 is positioned at the middle part of the middle-effect filter core 132, the filter core has finer filtration capability, and the air can gradually remove impurities and pollutants with different particle diameters when sequentially passing through each filter core, so that the air after multi-layer filtration can reach higher purification standard, and the air quality is effectively improved;
when the device body 1 continues to run for a period of time, the two first filtering areas 21 are blocked relatively, the driving gear 242 is rotated, and due to the meshing connection relationship between the fluted disc 241 and the driving gear 242, the rotation of the driving gear 242 drives the fluted disc 241 to synchronously rotate, so as to drive the extension disc 23 connected with the fluted disc 241 and the primary filter core 131 to rotate together, and along with the rotation process of the primary filter core 131, the replacement filtering area 22 originally close to the second side shell plate 113 is rotated to the position of the previous first filtering area 21, so that the replacement operation of the filtering areas is realized, and the filtering load of each area of the primary filter core 131 can be effectively balanced through the replacement mechanism of the filtering areas, so that the overall service life of the primary filter core 131 is prolonged;
when the equipment starts the rotation procedure of the primary filter core 131, the inner stay bar 32 and the surface of the secondary filter core 132 generate relative motion, so that the scraping and cleaning functions are realized on the surface of the secondary filter core 132, meanwhile, the inner walls of the two second side shell plates 113 are provided with a plurality of outer side posts 31, when the primary filter core 131 rotates, the surface of the primary filter core 131 can be contacted and rubbed with the outer side posts 31, the contact can effectively clean the surface of the primary filter core 131, dust and impurities adsorbed on the surface of the primary filter core are removed, and after the whole equipment body 1 is used for a period of time, the shell needs to be integrally disassembled, so that the inside of the equipment body 1 is integrally cleaned.
