Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
According to research, the filter element in the related art is found that after the filter cylinder and the filter disc are replaced for a plurality of times, the elasticity of the sealing ring for sealing the filter disc and the bottom of the filter element is reduced, so that when the clamping block of the sealing ring is clamped to the bottom of the filter element, the gap at the clamping part is enlarged, the gap between the sealing ring and the bottom of the filter is enlarged, and the sealing effect of the sealing ring is deteriorated. If the width of the gap is reduced by increasing the width of the clamping block, the sealing ring and the bottom of the filter are clamped too tightly, so that the disassembly is inconvenient.
Based on the above-mentioned study, the embodiments of the present disclosure provide a filter assembly for a vacuum cleaner and a method of using the same, in which a groove 311 is formed at the top of a wedge-shaped insert 310, and a supporting member 320 is disposed in the groove 311, and the supporting member 320 is used to prop open or pull inward the walls on both sides of the wedge-shaped insert 310, so that the gap between the wedge-shaped insert 310 and the insert hole 110 is reduced while the quick-release is satisfied.

Some embodiments of the invention are described in detail below with reference to the accompanying drawings. The following embodiments and features of the embodiments may be combined with each other without conflict.
Referring to fig. 1 and 2, at least one embodiment provides a filter assembly for a vacuum cleaner, comprising:
The tubular bracket 100 is formed by plugging a top cover 150 and a bracket body 140. When the filter cartridge 200 is assembled, after the bracket body 140 is detached from the top cover 150, the filter cartridge 200 is sleeved on the bracket body 140, and then the top cover 150 is covered on the direct body, so that the installation of the filter cartridge 200 is completed, and the structural schematic diagram of the separated top cover 150 and bracket body 140 of the cylindrical bracket 100 is shown in fig. 6.
And a filter cartridge 200 which is sleeved on the side wall of the tubular bracket 100.
Specifically, the filter cartridge 200 is a HEPA filter screen that can trap particles above 0.3 μm.
And a seal ring 300 provided at the bottom of the cylindrical holder 100.
The filter disc 400 is clamped on the sealing ring 300 and is connected with the cylindrical support 100 through the sealing ring 300.
It should be noted that, the filter disc 400 includes a filter screen and an annular frame made of elastic material for supporting the filter screen, wherein the filter screen is a HEPA filter screen.
Referring to fig. 2 and 3, a wedge-shaped insert 310 is disposed at the top of the sealing ring 300, and an insert hole 110 is disposed at the bottom of the cylindrical support 100 corresponding to the wedge-shaped insert 310.
The wedge-shaped insert 310 is an inverted trapezoid, the shape of the insert hole 110 is also an inverted trapezoid, and the wedge-shaped insert 310 is adapted to the size of the insert hole 110. In the mounting, the wedge-shaped insert 310 is inserted into the insert hole 110, and thus the mounting of the sealing ring 300 is completed.
The wedge-shaped insert 310 is provided with a recess 311 at the top. The deformability of the wedge-shaped insert 310 is improved by providing the groove 311, thereby facilitating the wedge-shaped insert 310 to be caught in the insert hole 110 and the disassembly.
The holding part 320 is disposed in the groove 311, when the wedge-shaped insert 310 is inserted into the insert hole 110, the holding part 320 pulls the walls at both sides of the wedge-shaped insert 310 inward to reduce the width of the wedge-shaped insert 310, and after the wedge-shaped insert 310 is inserted into the insert hole 110, the holding part 320 clamps the side wall of the wedge-shaped insert 310 with the inner wall of the insert hole 110.
Meanwhile, the requirement on the assembly precision between the sealing ring 300 and the cylindrical support 100 can be reduced, and the precision can be adaptively compensated through the propping piece 320.
When the wedge-shaped embedded block 310 is detached or installed, the wall bodies at the two sides of the wedge-shaped embedded block 310 are pulled inwards through the propping piece 320, so that the width of the wedge-shaped embedded block 310 is reduced, the detachment or installation of the sealing ring 300 and the filter disc 400 is facilitated, after the wedge-shaped embedded block 310 is inserted into the embedded hole 110, the side wall of the wedge-shaped embedded block 310 is tightly clamped with the inner wall of the embedded hole 110 through the propping piece 320, and the gap at the joint is reduced, so that the problem of the increase of the gap at the joint caused by the fact that the sealing ring 300 is detached for many times is solved while the quick detachment is not influenced.
The gap at the joint was in the range of 0.1mm to 0.3mm at the time of initial assembly. When the supporting piece 320 clamps the side wall of the wedge-shaped embedded block 310 and the inner wall of the embedded hole 110, the gap can be compensated, the compensation range is less than or equal to 0.5mm, the gap is further reduced, and at the moment, the gap range at the clamping position is between 0.05mm and 0.1 mm. After multiple disassembly, when the gap at the clamping part is not more than 0.5mm, the compensation can be performed through the propping piece 320, so that the risk of dust infiltration can be reduced, and the filtering precision of the filter assembly is ensured.
Referring to fig. 3 and 4, the supporting member 320 includes the following structures:
The insert rod 321 has one end penetrating through the seal ring 300 and extending into the groove 311 of the wedge-shaped insert block 310, and the other end sleeved with a return spring 322.
