Description

Technical Field

[0001] The utility model belongs to the technical field of filter elements, and in particular relates to a foam rubber line filter element. Background Art

[0002] Inside buildings, cars, vacuum cleaners, air conditioners and liquid filters, there are filters that filter various impurities such as dust contained in the inflowing gas or liquid. This filter is usually made of non-woven fabric, generally in the form of zigzag wrinkles. Among them, most of the plate filter elements used for air conditioning air filtration are mainly composed of a filter layer folded in a zigzag structure and an outer frame strip pasted outside the filter layer. The filter layer and the outer frame are mostly made of non-woven fabric materials such as polyester fiber and polypropylene fiber. This type of air filter element has the characteristics of large effective filtration area and soft structure.

[0003] In order to make the folded serrated filter layer of the filter element evenly spaced, glue lines are usually used to connect the serrated filter layers to make the serrated filter layers equally spaced, improve the strength of the serrated filter layers, and make the serrated filter layers less likely to deform (for example: Chinese invention patent application number CN201811651750.X discloses a vehicle air purifier filter element). However, in the existing air filter element, the glue line is only bonded to the tips of multiple serrated shapes to connect the multiple serrated shapes, and there is no glue bonding between the adjacent serrated surfaces. The glue line bonding strength is not high and it is easy to debond. Utility Model Content

[0004] The utility model aims to provide a foam rubber wire filter element, aiming to solve one of the technical problems existing in the prior art.

[0005] To achieve the above-mentioned purpose, an embodiment of the utility model provides a foam rubber line filter element, including a filter layer; the filter layer is folded into a serrated shape and forms a plurality of serrated portions, and a frame strip is bonded to the outer edge of the filter layer; a plurality of rubber lines are bonded to the serrated surface of one side of the filter layer, and each of the rubber lines is bonded to the serrated surface of the filter layer along the folding direction of the filter layer; the rubber line is a foam rubber line.

[0006] Optionally, the rubber line is transitionally provided with an arc portion at the tip of each sawtooth portion of the filter layer.

For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present invention can be understood according to specific circumstances.

[0025] In one embodiment of the present invention, referring to Figure 1 and Figure 2 , a foam rubber line filter element is provided, including a filter layer 100.

[0026] The filter layer 100 is folded into a sawtooth shape and forms a plurality of sawtooth portions 110 , and a frame strip 300 is bonded to the outer edge of the filter layer 100 .

[0027] A plurality of adhesive lines 200 are bonded to the serrated surface of one side of the filter layer 100 , and each of the adhesive lines 200 is bonded to the surface of the serrated portion 110 of the filter layer 100 along the folding direction of the filter layer 100 .

[0028] Wherein, the glue line 200 is a foam glue line 200 .

[0029] Compared with the prior art, the one or more technical solutions in the foam rubber line 200 filter element provided in the embodiment of the utility model have at least one of the following technical effects:

[0030] Reference Figure 1 and Figure 2 , each glue line 200 is bonded to the surface of the serration 110 of the filter layer 100 along the folding direction of the filter layer 100, and the plurality of serrations 110 of the filter layer 100 are connected by the glue line 200, so that the plurality of serrations 110 of the filter layer 100 are distributed at equal intervals. In addition, the glue line 200 is not only bonded to the tips 111 of the plurality of serrations 110, but also bonded between the surfaces of two adjacent serrations 110, so that the glue line 200 is firmly bonded to the surface of the serration 110 of the filter layer 100, which not only greatly improves the strength of the filter layer 100, but also makes the glue line 200 not easy to debond.

[0031] In addition, the glue line 200 is a foam glue line 200, which has good toughness and ductility, so that the foam glue line 200 filter element has more toughness and ductility, and can be bent and folded repeatedly, and the foam glue line 200 is not easy to break.

[0032] Further, refer to Figure 1 and Figure 2 The rubber line 200 is provided with an arc portion 210 at the tip 111 of each serrated portion 110 of the filter layer 100. By providing the arc portion 210, the elasticity of the rubber line 200 is improved, so that the rubber line 200 is not easy to break after repeated bending or folding, and the rubber line 200 can quickly elastically restore the filter layer 100 to its original state.

[0033] Further, refer to Figure 1 and Figure 2 , a plurality of adhesive lines 200 are also bonded to the surface of the serrated portion 110 on the other side of the filter layer 100, and each of the adhesive lines 200 is bonded to the surface of the serrated portion 110 of the filter layer 100 along the folding direction of the filter layer 100. By providing a plurality of adhesive lines 200 on both sides of the filter layer 100, the strength of the filter layer 100 is further improved, so that the plurality of serrated portions 110 of the filter layer 100 are not easily deformed during use, and the structure is stable.

[0034] Further, refer to Figure 1 and Figure 2 The rubber line 200 on one side of the filter layer 100 is overlapped or staggered with the rubber line 200 on the other side of the filter layer 100, so that the structure of the foam rubber line 200 filter element has diversity.

[0035] Further, refer to Figure 1 and Figure 2 The number of the glue lines 200 is two or more, so the number of the glue lines 200 can be determined according to production requirements or user requirements.

[0036] Further, refer to Figure 1 and Figure 2 The frame strip 300 is a non-woven fabric strip or a foamed fabric strip. The frame strip 300 is bonded to the outer edge of the filter layer 100 by glue, and has a simple structure and is easy to assemble.

[0037] During processing, the filter layer 100 is first folded into a zigzag shape, and then the filter layer 100 is unfolded. Then, the foam glue is introduced from the injection nozzle through a glue injection machine and attached to the surface of the filter layer 100. Finally, the filter layer 100 with the foam glue coated on the surface is folded manually or by a paper collection device and formed after the foam glue is cured. The foam glue forms a glue line on the surface of the filter layer 100 after curing.

[0038] The rest of this embodiment is the same as the first embodiment. The features not explained in this embodiment are all based on the explanations in the first embodiment and will not be described in detail here.

[0039] The above content is a further detailed description of the utility model in combination with specific preferred implementation methods, and it cannot be determined that the specific implementation of the utility model is limited to these descriptions. For ordinary technicians in the technical field to which the utility model belongs, without departing from the concept of the utility model, its architecture can be flexible and can derive a series of products. Just making a few simple deductions or substitutions should be regarded as belonging to the patent protection scope of the utility model determined by the submitted claims.
