Description

Dust collector filter screen convenient to disassemble and assemble Technical Field The utility model relates to the field of dust collector filter screens, in particular to a dust collector filter screen convenient to disassemble and assemble. Background The barrel type dust collector is a split dust collection device, which mainly comprises a dust collection barrel (host machine) and a suction head/hose, and is connected with the suction head for cleaning through the hose. Compared with an upright or handheld dust collector, the bucket dust collector is generally stronger in suction force and larger in capacity, and is suitable for cleaning large areas or deeply dedusting. When the existing barrel type dust collector is used, the motor cabin cover is only provided with the HEPA filter screen, and in the actual use process, even if the main filter screen near the dust collection barrel air inlet filters the entered impurities, a small amount of hair, paper scraps, sharp particles and other larger impurities still enter the dust collection barrel, so that the HEPA filter screen is blocked or the surface is scratched easily. Therefore, it is necessary to provide a new dust collector filter screen which is convenient to disassemble and assemble to solve the technical problems. Disclosure of utility model In order to solve the technical problems, the utility model provides a dust collector filter screen convenient to disassemble and assemble, which solves the problems that the HEPA filter screen is easy to block or scratch the surface in the actual use process because the HEPA filter screen is only installed at the position of the existing motor cabin cover. The dust collector filter screen convenient to disassemble and assemble comprises a motor cabin cover, wherein a HEPA filter screen is arranged on one side of the motor cabin cover, a connecting seat is fixed at the bottom of the HEPA filter screen, and an annular clamping groove is formed in the connecting seat; the HEPA filter screen outside is provided with the metal filter screen, metal filter screen bottom is fixed with annular fixture block, annular fixture block with annular draw-in groove gomphosis mutually. In a preferred embodiment, the metal screen is made of stainless steel. In a preferred embodiment, the connecting seat is symmetrically provided with two thread grooves, the annular clamping block is symmetrically provided with two through holes, and the connecting seat is connected with the annular clamping block through hand-screwed bolts. 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 blocks are matched with the positioning grooves in size. In a preferred embodiment, the metal screen has a pore size of 0.3mm to 2mm. In a preferred embodiment, the hand-screwed bolts are galvanised. The utility model has the beneficial effects that: The dust collector filter screen is provided with the metal filter screen at the outer part of the traditional HEPA filter screen, so that larger sundries such as hair, paper scraps, sharp particles and the like can be further intercepted, the larger sundries are prevented from being directly contacted with the HEPA filter screen, the blocking and damage risks of the HEPA filter screen are reduced, and the service life of the dust collector filter screen is prolonged; When clearing up this filter screen, the staff only need rotate whole filter screen earlier and make HEPA filter screen and motor cabin cover break away from, screw out corresponding hand screw bolt again, pull out the metal filter screen finally and can accomplish the separation between two filter screens, and the installation is the same, easy operation is convenient. Drawings FIG. 1 is a perspective view of a main structure of a filter screen of a dust collector, which is convenient to assemble and disassemble; FIG. 2 is a second perspective view of the main structure of the filter screen of the dust collector, which is convenient to disassemble and assemble; FIG. 3 is an enlarged schematic view of the structure A shown in FIG. 2; fig. 4 is an enlarged schematic view of the structure B shown in fig. 2; Fig. 5 is a side view of a main structure of a filter screen of a dust collector, which is convenient to disassemble and assemble.
