CN201578955U - Environment-friendly air filter cartridge - Google Patents

Abstract

The utility model relates to an air filter cartridge, in particular to an environment-friendly air filter cartridge, which comprises a paper cartridge (3), wherein synthetic films (6) are stuck to two ends of the paper cartridge (3). The synthetic films and the paper cartridge are bonded together through the hot melt, and the synthetic films are easy to decompose, and produce no chemical reaction process when being processed, therefore, as the environment-friendly air filter cartridge, the utility model needs no metal end cover and also saves the cost.

Description

The environment-friendly type air filter element

Technical field

The utility model relates to air cleaner cartridge, relates in particular to a kind of environment-friendly type air filter element.

Background technology

As shown in Figure 1, the filter core of air filter is formed by pleated refill 3 and upper and lower end cap 2,4 bondings at present, and in order in the product use air in the filtering cabin to be sealed, circle 1,5 also need be bonded and sealed respectively on upper and lower end cap 2,4.The being bonded and sealed property of refill and end cap directly has influence on the technical performance of air filter.Most end cap is to be formed by Zinc-coated steel-plated punch, bond with refill after the applying glue, the end cap of small part is a plastic end cover, mainly by the polypropylene injection mo(u)lding, adopt PUR and refill to bond, in the filter core bonding process, mainly adopt filter core glue that pleated refill and metal end are bondd and seal.No matter be galvanized steel plain sheet end cap or plastic end cover, use scrap after, can not decompose, all can pollute environment, and the filter core glue of its use is high polymer binder that environment is also had pollution.

Summary of the invention

Problem to be solved in the utility model is: a kind of environment-friendly type air filter element is provided, melts by heat that machine will synthesize film and refill bonds together, this synthetic film easily decomposes, add and do not have chemical reaction process man-hour, be a kind of environment-friendly materials, and need not metal end, saved cost.

The purpose of this utility model is achieved in that a kind of environment-friendly type air filter element, comprises refill 3, is bonded with synthetic film 6 at refill 3 two ends.

Synthetic film 6 by hot melting cohesion to refill 3.

Advantage of the present utility model is to have adopted synthetic film, and this synthetic film is made by the environment-friendly type macromolecule material, uses fuse machine then under heating, pressurized state, and through the regular hour, making refill be one with synthesizing the film welding.The back is scrapped in use only needs both do not had legacy with burning, and does not also influence environment, very environmental protection; And abandoned metal end, also saved cost.

Description of drawings

Fig. 1 is the structural representation of existing air filter;

Fig. 2 is a structural representation of the present utility model.

The specific embodiment

The utility model is described in further detail below in conjunction with the drawings and specific embodiments.

As shown in Figure 2, a kind of environment-friendly type air filter element of the utility model comprises refill 3, is bonded with synthetic film 6 at refill 3 two ends.

Synthetic film 6 be by hot melting cohesion to refill 3, promptly with fuse machine under heating, pressurized state, through the regular hour, making refill 3 and synthetic film 6 weldings is one.

Claims (2)

1. an environment-friendly type air filter element comprises refill (3), it is characterized in that: be bonded with synthetic film (6) at refill (3) two ends.

2. a kind of environment-friendly type air filter element according to claim 1 is characterized in that: synthetic film (6) arrives on the refill (3) by hot melting cohesion.
