Description

Multi-layer air purification filter

The present invention relates to a multilayer air purification filter.

With the advancement of society and the improvement of people's living standards, people have put forward higher requirements for the quality of life. People buy houses, decorate their homes, and apply and promote oil, coal, natural gas, chemical products, automobiles, etc., but bring a certain degree of pollution to our indoor and outdoor air while improving our living standards, especially in recent years. The decoration is increasingly luxurious, the use of household chemicals is extensive, and the indoor and outdoor air pollution caused by human activities such as smoking and cooking cannot be ignored. The quality of the environment directly affects people's health. Therefore, traditional filter materials have been unable to meet people's requirements, especially in terms of antibacterial and removal of toxic and harmful gases.

In order to solve the above problems, the present invention provides a multi-layer air purifying filter with simple structure and good filtering effect, which has the functions of removing moisture, antibacterial and removing harmful chemical substances.

The technical solution adopted by the novel to solve the problem is:

A multi-layer air purifying filter comprising a grid arranged on an outer layer and a honeycomb network sandwiched between two grids, and a fiber cloth layer containing activated carbon is disposed between the grid and the honeycomb network, the honeycomb network The interior is provided with a fiber mesh and a molecular sieve layer.

Preferably, the grid is a two-layer structure comprising a casing and a web attached to the casing.

Preferably, the cellular network is a five-layer structure comprising two layers of honeycomb casings, two layers of web sandwiched between two layers of honeycomb casings, and a molecular sieve layer sandwiched between two layers of webs.

Preferably, the upper end cover and the lower end cover which are disposed at both ends of the filter and which fix the above-mentioned square grid, honeycomb net and fiber cloth layer are further included.

Further, the inner side wall of the upper end cover and the lower end cover are provided with a mounting groove, and the mounting groove is provided with a hook for snapping the cellular net.

The beneficial effect of the novel is that the first layer of square grid contains a fiber mesh, which can filter the filamentous dust first. The cellular network containing the fiber mesh and the molecular sieve layer can adsorb water and filter harmful substances such as methanol, ethanol, hydrogen sulfide, sulfur dioxide, ethylene, and propylene. Black activated carbon fiber cloth has excellent sterilization and removal of harmful chemicals. The product as a whole has the function of multi-layer filtration, greatly improves the air purification efficiency, and is widely used, and can be used for various air purification equipments, purifying human living space places, including the interior space of the trolley.

The present invention will be further described with reference to the accompanying drawings and embodiments. Fig. 1 is a schematic view of the overall structure of the present invention; Fig. 2 is a schematic structural view of the present invention; Fig. 3 is a schematic structural view of the novel cellular network; Schematic.

A multi-layer air purifying filter as shown in FIGS. 1 to 3, comprising a grid 1 disposed on the outer layer and a cellular net 2 sandwiched between two grids 1, a grid 1 and a cellular network A fiber cloth layer 3 containing activated carbon is provided between the two, and the black activated carbon fiber cloth has excellent sterilization and removal of harmful chemicals. A fiber web 4 and a molecular sieve layer 5 are also disposed inside the honeycomb network 2.

Wherein, the grid 1 is a double-layer structure comprising an outer casing and a fiber web 4 adhered to the outer casing, and the fiber web 4 is adhered to the outer casing of the square grid 1 by injection molding. Of course, the grid 1 may not be equipped with the fiber web 4. The novel adopts a grid 1 having a fiber web 4 on the first layer of the filter screen, which can filter the filamentous dust first, since the middle has passed the honeycomb network 2 The fine filtration, so the last layer of the grid 1 does not need to install the fiber web 4, mainly for the fixed protection, the honeycomb network 2 is ultrasonically welded together.

Wherein, as shown in FIG. 3, the cellular network 2 is a five-layer structure comprising two layers of honeycomb casing 21, two layers of fiber webs sandwiched between two layers of honeycomb casings 21, and sandwiched between two layers of fiber webs. 4 between the molecular sieve layer 5. The fiber web 4 is also adhered to the honeycomb outer casing 21 of the honeycomb net 2 by injection molding. The molecular sieve layer 5 is composed of zeolite and uniformly dispersed on the fiber web 4 by a pellet machine, and contains the fiber web 4 and the molecular sieve layer 5. The honeycomb network 2 can adsorb water and filter substances such as methanol, ethanol, hydrogen sulfide, sulfur dioxide, ethylene, propylene and the like which have a pore diameter of 4A.

Further, at both ends of the filter of the present invention, an upper end cover 61 and a lower end cover 62 for clamping and fixing the square grid 1, the honeycomb net 2, and the fiber cloth layer 3 are further provided. The fiber cloth layer 3 is positioned between the square grid 1 and the cellular net 2 by ultrasonic welding. As shown in FIG. 4, the inner side walls of the upper end cover 61 and the lower end cover 62 are provided with mounting grooves 63. The mounting grooves 63 are provided with hooks 64 for snapping the cellular net 2. During installation, the square grid 1 and the honeycomb network 2 and the fiber cloth layer 3 are first inserted into the upper end cover 61 or the mounting groove 63 of the lower end cover 62 in sequence, and the hook 64 will catch the cellular net 2, after installation, The entire end of the filter can be inserted by inserting the end cap on the other end. The outer side walls of the upper end cover 61 and the lower end cover 62 are also provided with a buckle for engaging the filter on the external device.

The above description is only for the principles and embodiments of the present invention, and any simple modifications and variations made in accordance with the spirit of the present invention are within the scope of the claimed invention.
