[0005] In order to solve the above technical problems, the utility model provides a dust collector filter screen convenient to dismount, solves the problem that the existing motor cabin cover place only installs HEPA filter screen, in the actual use process, easy to cause HEPA filter screen to be blocked or surface be scratched.
[0006] The dust collector filter screen convenient to dismount provided by the utility model includes motor cabin cover, HEPA filter screen is installed on one side of the motor cabin cover, the bottom of the HEPA filter screen is fixed with connecting seat, and annular clamping groove is formed in the connecting seat.
[0007] The outer side of the HEPA filter screen is provided with metal filter screen, the bottom of the metal filter screen is fixed with annular clamping block, and the annular clamping block is embedded with the annular clamping groove.
[0008] In a preferred embodiment, the metal filter screen adopts stainless steel material.
[0009] In a preferred embodiment, two screw grooves are symmetrically formed in the connecting seat, two through holes are symmetrically formed in the annular clamping block, and the connecting seat and the annular clamping block are connected through hand screw bolt.
[0010] In a preferred embodiment, two positioning blocks are fixed on the annular clamping block, two positioning grooves are formed in the connecting seat, and the positioning block and the positioning groove are matched in size.
[0011] In a preferred embodiment, the metal filter mesh has a mesh size of 0.3mm-2mm.
[0012] In a preferred embodiment, the hand screw bolt is galvanized.
[0013] The beneficial effects of the present utility model are as follows:
[0014] The dust collector filter mesh further intercepts larger sundries such as hair, paper scraps and sharp particles by setting a layer of metal filter mesh outside the traditional HEPA filter mesh, prevents the sundries from directly contacting the HEPA filter mesh, reduces the risk of blocking and damage of the HEPA filter mesh, and prolongs the service life of the HEPA filter mesh.
[0015] When cleaning the filter mesh, the staff only needs to rotate the entire filter mesh to separate the HEPA filter mesh from the motor cabin cover, rotate the corresponding hand screw bolt out, and finally pull out the metal filter mesh to complete the separation between the two filter meshes.

DETAILED DESCRIPTION
[0022] The present utility model will be further described in combination with the drawings and embodiments.
[0023] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 andFigure 5 ,in Figure 1 The main structure of the easily detachable vacuum cleaner filter provided by this utility model is shown in a three-dimensional view. Figure 1 ; Figure 2 The main structure of the easily detachable vacuum cleaner filter provided by this utility model is shown in a three-dimensional view. Figure 2 ; Figure 3 for A magnified structural diagram of A is shown below; for A schematic diagram of the enlarged structure of B shown; The main structural side view of the vacuum cleaner filter that is easy to disassemble and assemble according to this utility model.
[0024] In the specific implementation process, such as As shown, it includes a motor compartment cover 1, on one side of which a HEPA filter 2 is installed. The top of the HEPA filter 2 is provided with a connector 12 that connects to the motor compartment cover 1. The HEPA filter 2 can be removed from the motor compartment cover 1 simply by rotating it. For the specific principle, those skilled in the art can refer to the SUPOR VCT80P canister vacuum cleaner.
[0025] The bottom of the HEPA filter 2 is fixed with a connecting seat 3, and the connecting seat 3 has an annular groove 4. A metal filter 5 is disposed on the outside of the HEPA filter 2, that is, the HEPA filter 2 is located inside the metal filter 5. The top inner side of the metal filter 5 contacts the outer wall of the connector 12 of the HEPA filter 2. The metal filter 5 is made of stainless steel and has a pore size of 0.3mm-2mm. For fine filtration, the filter size is 0.3-0.5mm, suitable for home environments, and can effectively intercept pet hair and fine dust, but requires frequent cleaning to prevent clogging. For general filtration, the filter size is 0.5-1mm, balancing filtration efficiency and airflow resistance, suitable for most home and commercial scenarios. For coarse filtration, the filter size is 1-2mm, used in industrial environments, to intercept large particles such as wood chips and plastic flakes, reducing maintenance frequency.
[0026] The bottom of the metal filter screen 5 is fixed with an annular clamping block 6 which is embedded with the annular clamping groove 4, two screw grooves 7 are symmetrically arranged on the connecting seat 3, two through holes 8 are symmetrically arranged on the annular clamping block 6, the connecting seat 3 and the annular clamping block 6 are connected through hand-tightening bolts 9, the hand-tightening bolts 9 are galvanized to enhance the service life, when cleaning the filter screen, the staff only needs to rotate the entire filter screen to make the HEPA filter screen 2 separate from the motor compartment cover 1, then rotate the corresponding hand-tightening bolts 9 out, and finally pull out the metal filter screen 5 to complete the separation between the two filter screens, and the installation is the same, which is simple and convenient, the annular clamping block 6 is fixed with two positioning blocks 10, two positioning grooves 11 are arranged on the connecting seat 3, the positioning blocks 10 and the positioning grooves 11 are matched in size, so that when the user reinserts the annular clamping block 6 into the annular clamping groove 4 after cleaning the filter screen, the screw grooves 7 and the through holes 8 are located in the same plane.
[0027] The working principle of the utility model is: the dust collector filter screen of the utility model further intercepts larger sundries such as hair, paper scraps and sand by setting a layer of metal filter screen 5 outside the traditional HEPA filter screen 2, prevents the sundries from directly contacting the HEPA filter screen 2, reduces the blocking risk of the HEPA filter screen 2, and prolongs the service life of the HEPA filter screen 2.
[0028] When cleaning the filter screen, the staff only needs to rotate the entire filter screen to make the HEAP filter screen 2 separate from the motor compartment cover 1, then rotate the corresponding hand-tightly screwed bolts 9 out, and finally pull out the metal filter screen 5 to complete the separation of the two filter screens, and the installation is the same, which is simple and convenient.
