Description

Novel structure filter

Technical Field

The utility model relates to a filter of air purification equipment, in particular to a novel structure filter.

Background

The filter is a key component of the air purification equipment and is used for filtering harmful substances such as smoke, dust, bacteria and the like in the air. Common filters in the market are composed of a metal shell which is welded and formed and then filled with filter materials, an aluminum alloy plate and filter materials which are filled with glue and combined and formed, a plastic shell or simple paperboard and a filter unit which are glued and combined and formed, and the like.

The conventional filter has the following problems:

(1) the metal structure is suitable for medium and large-scale air purification equipment, the space utilization rate is lower when the metal structure is applied to small-scale equipment, the metal frame body adopts welding and riveting modes, the distortion is easy, the appearance is not attractive, and the assembly precision is lower.

(2) The plastic or paperboard structure can be suitable for small-sized air purification equipment, has beautiful appearance but low durability, and is easy to cause damage, deformation and the like of the filter material.

(3) The traditional filter has complex assembly process, and most of the traditional filters are shaped by using sealant, so that secondary pollution is easily caused.

(4) The replaceability is limited, the metal shell is easily deformed and damaged when being disassembled, and the plastic shell or the simple paperboard is mostly a disposable consumable article.

Disclosure of Invention

To the problem that current filter exists, design a novel structure filter suitable for small-size equipment.

The utility model is realized by adopting the following technical scheme: the utility model provides a novel structure filter, includes barrel subassembly, barrel and filtering material down, wherein goes up the barrel subassembly and includes annular protecting wire net and last barrel, goes up the upper end and the lower extreme of barrel and all opens, and annular protecting wire net is fixed at the upper end opening part of last barrel, and filtering material places in last barrel, and last barrel inner wall lower part has the internal thread, and the upper end and the lower extreme of barrel are all opened down, and the outer wall upper portion of barrel has the external screw thread down, and barrel and last barrel screw-thread fit down, lower barrel press filtering material admittedly in last barrel. The upper barrel body and the lower barrel body are assembled in a threaded mode, so that the assembly precision is improved, and the deformation is small.

Foretell novel structure filter, annular protecting wire net include concentric three ring body, connect through the muscle between the three ring body, and the lower surface mounting protecting wire net of ring body.

The upper cylinder component of the novel structure filter further comprises two pressing blocks, and the two pressing blocks are symmetrically fixed on the middle ring body of the annular protecting net. When the filter is installed on the air purification equipment, the pressing block can be used for positioning, and the filter is convenient to install.

The novel structure filter is characterized in that the wall of the lower cylinder, which is exposed out of the upper cylinder, is provided with an O-shaped ring. When the filter is installed on the air purification equipment, the lower cylinder body needs to be connected with other parts in the equipment, and the O-shaped ring realizes sealing connection.

In the novel structure filter, the filter material is filter paper.

The utility model provides a filter with a small structure, which has high dimensional precision, regular appearance and convenient processing and manufacturing. The filter mainly comprises a stainless steel main body and a filtering material, wherein the main body part adopts a thread assembly mode and is matched with a special filter protecting net and a positioning part, so that the filter is convenient to install, use and replace. Compared with the existing structure, the filter material can fully exert the performance of the filter material, reduce the resistance and improve the purification effect.

Detailed Description

As shown in figure 1, the novel structure filter consists of an upper cylinder assembly 1, a lower cylinder 2, a filter material 3 and an O-shaped ring 4. As shown in fig. 2 and 3, the upper cylinder assembly 1 is composed of an annular protecting net 5, a pressing block 6 and an upper cylinder 7. The upper barrel body 7 and the lower barrel body 2 are made of stainless steel and are matched by machining threads, so that the filter material is convenient to assemble and replace. The lower cylinder body 2 replaces the sealing glue for shaping in a way of pressing the filtering material, and the bottom surface of the pressing block 6 is square (10 mm multiplied by 10 mm). The annular net-shaped protecting net is designed, and the positioning design is integrated, so that the filter pressing block is accurately positioned. The filtering area is increased in a limited structural space, and the purifying effect is improved. The filter structure is miniaturized while ensuring the performance of products, so that the filter structure is more widely applied to small-sized equipment.

The filter has the following advantages:

(1) the welding points are reduced, the main body part is in machined thread fit, the assembly precision is improved, the deformation is small, and the appearance is attractive.

(2) The filter is made of a material with high durability and is miniaturized, so that the filter is suitable for small air purification equipment.

(3) The filter assembling procedure is simplified, and the operation difficulty is reduced. The design compresses tightly the mode and replaces sealed glue design, has avoided secondary pollution.

(4) The filtering material can be quickly replaced.
