Problems solved by technology

It can be seen that the filter element in the air purifier will emit a large amount of toxic and harmful gases, which will cause greater pollution to the air in the environment, which is not conducive to air purification and will cause great harm to people's health
[0004] Therefore, in the process of purifying and treating the air, the existing air filter elements will instead emit components that pollute the air, which is not conducive to the purification of the air and reduces the air quality of the surrounding environment.

Embodiment 1

[0039] Such as figure 1 , figure 2 , image 3 As shown, this embodiment discloses an adhesive-free air filter element, which includes two air filter bodies interlocked with each other, a filter cavity is formed between the two air filter bodies, and a filter layer 4 is arranged in the filter cavity; The air filter body comprises a filter surface layer 5 and a flange edge 3 connected to the filter surface layer 5, a number of cover-shaped raised structures 1 are continuously arranged on one side of the filter surface layer 5, and the flange edge is arranged on the filter surface On the other side of the layer 5, the edge 2 of the filter surface layer 5 is pressed against the flange edge 3.

[0040]The air filter element disclosed above can be used to filter particulate pollutants (pollen, fluff, hair, dust, cigarettes, smog, etc.), filter gaseous pollutants (formaldehyde, toluene, ammonia, carbon monoxide, carbon dioxide, nitrogen dioxide, etc.) , hydrocarbons and other VOC...

Embodiment 2

[0052] This embodiment discloses a non-adhesive air filter element, which is the same as in Embodiment 1: it includes two air filter bodies that are interlocked with each other, a filter cavity is formed between the two air filter bodies, and a filter cavity is provided in the filter cavity. Filter layer 4; the air filter body includes a filter surface layer 5 and a flange edge 3 connected with the filter surface layer 5, and several cover-shaped raised structures 1 are continuously arranged on one side of the filter surface layer 5, and the method The flange edge is arranged on the other side of the filter surface layer 5 , and the edge 2 of the filter surface layer 5 is pressed against the flange edge 3 .

[0053] The air filter element disclosed above can be used to filter particulate pollutants (pollen, fluff, hair, dust, cigarettes, smog, etc.), filter gaseous pollutants (formaldehyde, toluene, ammonia, carbon monoxide, carbon dioxide, nitrogen dioxide, etc.) , hydrocarbo...

Embodiment 3

[0057] This embodiment discloses a filter element production process for producing the adhesive-free air filter element described in Embodiment 1 and Embodiment 2, including:

[0058] Provide a cover-shaped raised structure on the filter surface layer by means of hot pressing or ultrasonic forming;

[0059] Connect the filter surface layer with the flange edge;

[0060] A filter layer is arranged on the inner side of the filter surface layer;

[0061] Connect the flange sides of the two filter bodies by thermocompression or ultrasonic forming.

[0062] In this embodiment, the steps in the above-mentioned technical solution are optimized, and the following feasible solutions are given: the connection of the filter surface layer with the flange edge and the setting of the filter layer on the inner side of the filter surface layer are all formed by hot pressing way to achieve.

Abstract

The invention relates to the technical field of air filters, in particular to an adhesive-free air filter element and a production process. The adhesive-free air filter element comprises two air filtering bodies which are buckled with each other, wherein a filtering cavity is formed between the two air filtering bodies, and filtering layers are arranged in the filtering cavity; each of the air filtering body comprises a filtering surface layer and a flange edge connected with the filtering surface layer; and a plurality of cover-shaped bulge structures are continuously arranged on one side surface of each filtering surface layer, the flange edge is arranged on the other side surface of each filtering surface layer, and the edge of each filtering surface layer is in press fit with the flange edge. The production process for the filter element comprises the following steps: arranging the cover-shaped bulge structures on the filtering surface layers in a hot pressing or ultrasonic formingmanner; connecting the filtering surface layers with the flange edges; arranging the filtering layers on the inner side surface of the filtering surface layers; and connecting the flange edges of thetwo filtering bodies in a hot-pressing manner or an ultrasonic forming manner. According to the process provided by the invention, no adhesive is adopted in the production process, and the preparedfiltering bodies do not emit toxic and harmful gases such as VOC to the outside and improve air purification efficiency.

Description

technical field [0001] The invention relates to the technical field of air filters, in particular to an adhesive-free air filter element and a production process. Background technique [0002] At present, air purifiers, fresh air fans, especially children's air purifiers and other products used by many families are household products that bring health, but many purifiers themselves use a lot of glue and adhesives. As we all know, adhesives will emit VOC (volatile organic compounds, volatile organic compounds) gaseous pollutants, such as formaldehyde and other gases, so adhesives are a source of pollution. Many air purifier filters on the market should be sealed for 24 hours and then removed. The VOC emitted by it was detected, and it was found that there were VOC exceeding the standard. [0003] The current situation is that the filter element in the air purifier uses a large amount of adhesives, for example: sub-sensitive hot melt glue is used in the composite process of c...
