Description

Technical Field

[0001] The utility model relates to the technical field of filters, in particular to a filter convenient for replacing a filter element. Background Art

[0002] A pre-filter is the first coarse filtration device for the whole-house water use, which can filter large particulate matters such as sediment, rust, insect eggs, and bloodworms in tap water. The pre-filter is generally installed at the front end of the pipeline, so it is named with the word "pre"; and "filtration" refers to the basic principle of such devices.

[0003] The pre-filter of the prior art filters the whole-house water through the filter element in its own shell. After the pre-filter is used for a long time, the filter element in the pre-filter is often contaminated and needs to be replaced regularly. However, the cylinder of the pre-filter and the water-passing shell are usually connected by a threaded connection. However, when the cylinder of the pre-filter is replaced, it often contains a lot of water. This causes a downward force between the threads of the shell and the cylinder when the cylinder is rotated counterclockwise and disassembled below the water-passing shell of the pre-filter, making it inconvenient to disassemble the cylinder of the filter and not conducive to the quick replacement of the filter element. For this reason, we propose a filter convenient for replacing a filter element. Content of the Utility Model

[0004] The main purpose of the utility model is to provide a filter convenient for replacing a filter element. An external connection mechanism is improved at the clamping cover and the receiving cylinder below the filter cover body. Then, the receiving cylinder can be clamped into the clamping cover with a double-sealing structure. The L-shaped cover plate outside the clamping cover is clamped at the L-shaped bottom embedding plate outside the receiving cylinder. At this time, a plug bolt can be inserted and pinned between the L-shaped cover plate and the L-shaped bottom embedding plate. After the plug bolt is pulled out, the receiving cylinder and the clamping cover can be directly separated, so as to conveniently take out the filter element in the receiving cylinder for replacement; and the filter of the utility model with a clamping and combined installation does not have the problem that the threaded structure is not easy to unscrew compared with the filter with a threaded connection installation, and can effectively solve the problems in the background art.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A filter for facilitating the replacement of a filter element, comprising a filter cover body, a clamping cover and a containing cylinder. The clamping cover is installed below the filter cover body, and a containing cylinder with a filter element embedded therein is inserted into the clamping cover. It further includes an external connection mechanism. The external connection mechanism includes an embedded plate, a support ring, a sealing conical ring, a sealing ring, an L-shaped bottom embedded plate, an L-shaped cover plate and an embedding bolt. A support ring is clamped into the mouth of the containing cylinder, and embedded plates protrude symmetrically from the outer ring wall of the support ring. Embedding grooves for clamping the embedded plates are formed in the wall of the mouth of the containing cylinder. The outer ring surface of the support ring protruding from the containing cylinder is fixedly provided with a sealing conical ring, and the sealing conical ring is upwardly clamped into the clamping cover. An outer ring groove for clamping the sealing ring is formed at the outer cylinder wall of the containing cylinder embedded in the clamping cover. L-shaped bottom embedded plates are symmetrically fixed to the outer edge of the ring cylinder of the containing cylinder. L-shaped cover plates for clamping the L-shaped bottom embedded plates are symmetrically fixed to the outer cover body of the clamping cover, and outer embedding holes and inner embedding holes are respectively formed in the plate bodies of the L-shaped cover plate and the L-shaped bottom embedded plate. The embedding bolt is inserted between the outer embedding hole and the inner embedding hole.

[0007] Wherein, the ring body of the sealing conical ring is an elastic ring body, and the small ring mouth of the sealing conical ring faces the ring mouth of the support ring;

[0008] By adopting the above technical solution, the support ring supports the sealing conical ring, and its large ring mouth is upwardly engaged with the clamping cover at the containing cylinder, so that the sealing conical ring is attached to the inner wall of the clamping cover for sealing.

[0009] Wherein, the thickness of the ring body of the sealing ring is greater than the depth of the outer ring groove;

[0010] By adopting the above technical solution, after the ring body of the sealing ring is clamped into the outer ring groove, part of the ring body can be exposed outward, so that a sealing position can be formed after the containing cylinder with the sealing ring is embedded into the clamping cover.

[0011] Wherein, the L-shaped plate body of the L-shaped cover plate is embedded below the L-shaped upper plate body of the L-shaped bottom embedded plate, and the plate lengths of the L-shaped cover plate and the L-shaped bottom embedded plate are the same;

[0012] By adopting the above technical solution, the L-shaped cover plate can be better covered outside the L-shaped bottom embedded plate for opposing engagement.

[0013] Wherein, an annular ribbed ring protrudes from the bolt body of the embedding bolt;

[0014] By adopting the above technical solution, when the bolt body of the embedding bolt is embedded into the outer embedding hole and the inner embedding hole, the ribbed ring of the embedding bolt can increase the surface roughness of the bolt body and improve the embedding firmness of the embedding bolt with the outer embedding hole and the inner embedding hole.

[0015] Wherein, the size of the groove body of the embedding groove is the same as the size of the plate body of the embedded plate;

[0016] By adopting the above technical solution, the embedded plate can be adaptively clamped into the embedding groove, facilitating the support of the support ring in the containing cylinder.

[0017] Compared with the prior art, the utility model has the following beneficial effects:

[0018] The utility model is improved by arranging an external connection mechanism at the clamping cover and the cylinder below the filter cover body. Then, the cylinder can be clamped into the clamping cover with a double-channel sealing structure. The L-shaped cover plate outside the clamping cover covers the L-shaped bottom embedded plate outside the cylinder for clamping. At this time, a bolt can be inserted and pinned between the L-shaped cover plate and the L-shaped bottom embedded plate. After the bolt is pulled out, the cylinder and the clamping cover can be directly separated, so as to facilitate the removal of the filter element in the cylinder for replacement;

[0019] Moreover, compared with the filter installed by screw connection, the clamping type combined filter of the utility model will not have the problem that the thread structure is not easy to unscrew. At the same time, the double-channel sealing structure realizes water leakage prevention when the cylinder and the clamping cover are fitted, greatly facilitating the replacement of the filter element of the filter and ensuring the convenient maintenance and use of the filter.

An embedded groove 5 for clamping the embedded plate 6 is formed in the wall of the mouth of the receiving cylinder 3. The outer ring surface of the support ring 7 protruding from the receiving cylinder 3 is fixedly provided with a sealing cone ring 8, and the sealing cone ring 8 is upwardly clamped into the clamping cover 2. An outer ring groove 9 for clamping the sealing ring 10 is formed in the outer cylinder wall of the receiving cylinder 3 where it is embedded in the clamping cover 2. L-shaped bottom embedded plates 11 are symmetrically fixed to the outer edge of the ring cylinder of the receiving cylinder 3. L-shaped cover plates 12 for clamping the L-shaped bottom embedded plates 11 are symmetrically fixed to the outer cover body of the clamping cover 2, and outer embedding holes 13 and inner embedding holes 14 are respectively formed in the plate bodies of the L-shaped cover plates 12 and the L-shaped bottom embedded plates 11, and an embedding bolt 15 is inserted between the outer embedding hole 13 and the inner embedding hole 14.

[0026] Among them, the ring body of the sealing cone ring 8 is an elastic ring body, and the small ring opening of the sealing cone ring 8 faces the ring opening of the support ring 7;

[0027] By adopting the above technical solution, the support ring 7 supports the sealing cone ring 8 so that its large ring opening is upwardly engaged with the clamping cover 2 at the receiving cylinder 3, enabling the sealing cone ring 8 to be attached to the inner wall of the clamping cover 2 for sealing.

[0028] Among them, the thickness of the ring body of the sealing ring 10 is greater than the depth of the outer ring groove 9;

[0029] By adopting the above technical solution, after the ring body of the sealing ring 10 is clamped into the outer ring groove 9, part of the ring body can be exposed outward, so that a sealing position can be formed after the receiving cylinder 3 with the sealing ring 10 is embedded into the clamping cover 2.
