In modern industrial production, vacuum cleaners play a very important role in aspects such as cleaning the production environment and dust control. Vacuum cleaners can be classified into vertical, horizontal, and portable types according to their structures, or simply divided into wired and wireless types. Wired vacuum cleaners have poor portability and may have problems such as wire entanglement and insufficient length during use; wireless vacuum cleaners are free from the restraint of wires and are more convenient to move.

The dust collection box is installed at the bottom of the cyclone separator, one end of the pipeline system is fixedly connected to the top of the cyclone separator, and the other end of the pipeline system is fixedly connected to the power component. The separation by the cyclone separator has a simple structure, no moving parts, and low cost. However, this structure has a low separation efficiency for particles with a diameter smaller than the cut-off particle size, and a large amount of small-particle dust will remain in the separated gas.

Detailed implementation manners

[0025] The present utility model will be further described below in conjunction with the accompanying drawings and implementation manners.

[0026] Please refer to Figures 1 - 8 , where Figure 1 Schematic diagram of the overall structure of the vacuum cleaner with a cyclone filtration structure provided by the present utility model; Figure 2 Schematic diagram of the internal structure provided by the present utility model; Figure 3 Schematic diagram of the partial split structure provided by the present utility model; Figure 4 Schematic diagram of the installation position structure of the annular frame provided by the present utility model; Figure 5 Schematic diagram of the installation position structure of the fixed frame provided by the present utility model; Figure 6 Schematic diagram of the cross-sectional structure of the engaging member and the engaging groove provided by the present utility model; Figure 7 Schematic diagram of the cross-sectional structure of the limiting post and the limiting hole provided by the present utility model; Figure 8 Schematic diagram of the movement trajectory of the internal objects during the operation of the cyclone separator provided by the present utility model.

[0027] During the specific implementation process, as Figures 1 - 8As shown in the figure, a vacuum cleaner with a cyclone filtration structure includes a housing 16, a power assembly 1, a cyclone separator 2, a dust collection box 3, and a pipeline system 4. The power assembly 1, the cyclone separator 2, the dust collection box 3, and the pipeline system 4 are all installed inside the housing 16. The top of the cyclone separator 2 is fixedly connected to one end of the pipeline system 4, and the other end of the pipeline system 4 is fixedly connected to the power assembly 1. A filter element is installed in the pipeline system 4 above the cyclone separator 2;

[0028] The power assembly 1 is a fan installed at one end of the pipeline system 4. The pipeline system 4 is the pipeline in the vacuum cleaner. The upper part of the main body of the cyclone separator 2 is cylindrical, and the lower part is conical. The cyclone separator 2 is a device that separates dust particles from the air flow by the centrifugal force generated by the high-speed rotation of the fluid itself. The dust-containing gas enters the cylinder from the tangential rectangular inlet at the upper part of the cylinder and rotates spirally downward along the outer wall. At the same time, under the action of centrifugal force, the particles are thrown towards the wall of the device and separated from the air flow. Under the action of gravity, they slide down along the wall of the device to the ash discharge port at the bottom of the cone. After the gas from which the dust has been removed reaches the bottom of the cone, it turns upward and rotates upward along the axis. Finally, it is discharged from the central exhaust pipe at the top. The gas reaching the bottom of the cone does not enter the ash hopper but goes upward along the central axis because in the cyclone separator 2, due to the high-speed rotation of the air flow, a negative pressure is generated in the area of the central axis. When the air flow reaches the bottom of the cone, it is sucked by the negative pressure and then discharged upward along the central axis. The sealing performance between the cyclone separator 2 and the dust collection box 3 is very important. If the sealing is not good, if the bottom dust collection hopper is not sealed well, the gas will penetrate into the device, resulting in a serious decrease in the separation efficiency. The rotation of the bottom air flow upward, which causes some of the particles that have settled to be re-rolled up, is an important factor affecting the cyclone separation efficiency;

[0029] The filter element includes an annular frame 5 and a fixed frame 6. A filter material is arranged inside the annular frame 5. The filter material can be HEPA material, activated carbon or synthetic fiber. The HEPA filter is short for High Efficiency Particulate Air Filter, which can capture particles above 0.3 microns and has a filtration efficiency as high as 99.97%. The HEPA material is usually made of glass fiber, has excellent filtration performance and a long service life. The activated carbon filter can adsorb harmful gases and odors and has a good effect on removing harmful substances such as formaldehyde and benzene in indoor air. The activated carbon material is usually made from substances with a high carbon content (such as coconut shells, fruit shells, wood, etc.) through high-temperature carbonization and activation treatment. The synthetic fiber filter has a relatively high filtration efficiency and relatively low cost. This material is usually used to manufacture some mid-range vacuum cleaner filter elements. Limiting grooves 7 are opened at opposite positions on the top and bottom of the annular frame 5. Limiting holes 8 are opened on the same side wall of the two limiting grooves 7. Two limiting members are fixedly connected to the corresponding positions of the pipeline system 4 and the limiting holes 8. The ends of the two limiting members are adapted to the two limiting holes 8. The fixed frame 6 is sleeved outside the annular frame 5 and is movably connected to the pipeline system 4. The limiting member includes a connecting rod 9 and a limiting post 10. One end of the connecting rod 9 is fixedly connected to the inner wall of the pipeline system 4, and the other end of the connecting rod 9 is fixedly connected to one end of the limiting post 10. The limiting post 10 is adapted to the limiting hole 8. The inner wall structure of the fixed frame 6 is adapted to the outer wall structure of the annular frame 5. Clamping members 17 are fixedly connected to both ends of the fixed frame 6. A clamping groove 11 is opened at the corresponding position of the pipeline system 4 and the clamping member 17. The cross-section of the clamping groove 11 is an "L" structure. The clamping member 17 includes a fixed block 12. One end of the fixed block 12 is fixedly connected to the fixed frame 6, and a groove is opened at the other end of the fixed block 12. A clamping spring 13 is fixedly connected to the inner bottom wall of the groove opened by the fixed block 12. A clamping block 14 is fixedly connected to the free end of the clamping spring 13. The clamping block 14 is adapted to the groove, and the clamping block 14 is adapted to the clamping groove 11. Sealing gaskets 15 are fixedly connected to both the bottom surface and the top surface of the annular frame 5. Both of the two sealing gaskets 15 are in a slope structure. When the fixed frame 6 is completely inserted, the sealing gasket 15 is squeezed. The material of the sealing gasket 15 can be rubber or polytetrafluoroethylene. A groove is opened on the side wall of the limiting post 10. A limiting spring 18 is fixedly connected to the inner bottom wall of the groove of the limiting post 10. A limiting block 19 is fixedly connected to the free end of the limiting spring 18. The top of the limiting block 19 is in a hemispherical structure. A groove adapted to the end of the hemispherical structure is opened on the inner side wall of the limiting hole 8.

[0030] The working principle provided by the present utility model is as follows: When installing the filter element, first place the annular frame 5 at the corresponding position of the pipeline system 4, rotate the annular frame 5 to engage the limit post 10 in the limit hole 8, install the fixed frame 6 at the corresponding position of the pipeline system 4, the pipeline system 4 squeezes the engaging block 14, the engaging spring 13 is compressed, and the engaging block 14 is placed in the groove formed in the fixed block 12. When the engaging block 14 moves from one end of the "L"-shaped structure of the engaging groove 11 to the other end of the "L"-shaped structure of the engaging groove 11, the engaging block 14 extends out of the engaging groove 11, the engaging spring 13 is released, and the engaging block 14 interacts with the engaging groove 11, so that the fixed frame 6 is limited. When it is necessary to replace the filter element, press the engaging block 14 to disassemble the fixed frame 6, and rotate the annular frame 5 in the opposite direction to that when installing the annular frame 5 to disassemble and replace the annular frame 5.
