Detailed Description
Referring to fig. 1, an exploded cross-sectional view of a filter cartridge for an air filter of an on-board air conditioner according to an embodiment of the present invention is shown. The filter element of the air filter at least comprises: silver-copper ion-containing fiber filter layer 1.
Wherein, the silver-copper ion-containing fiber filter layer 1 is formed by compounding a carrier 11 (such as silver-copper zeolite) containing silver-copper ions and a fiber substrate 12. In use, the fibrous substrate 12 on the silver-copper ion-containing fibrous filter layer 1 can filter to some extent the fine dust particles having a larger diameter in the air when the air to be filtered passes through the layer. Meanwhile, because the silver-copper ion-containing fiber filter layer 1 further has the carrier 11 containing silver-copper ions, when air passes through the silver-copper ion-containing fiber filter layer 1, silver ions and copper ions using silver-copper zeolite as a carrier are dissociated, wherein the copper ions damage cell membranes by being adsorbed on the cell membranes of bacteria or on the membrane surfaces of cells parasitized by viruses, and the copper ions or the silver ions interfere with the metabolic processes of the cells or the action of various enzymes by entering the inside, so that the cell structures are destroyed and finally die, thereby realizing the bactericidal and antiviral effects. Therefore, the silver-copper ion-containing fiber filter layer 1 can filter slightly larger dust particles in the air to a certain extent, and simultaneously plays a role in sterilizing and disinfecting the dust particles in the air, so that bacteria and viruses carried in the filtered air are reduced or even removed, the spread of the outside germ or virus-carrying air in the vehicle is prevented, and a good and healthy environment in the vehicle is guaranteed.
Preferably, the silver-copper ion containing carrier 11 may be embedded in the fibers in the fibrous substrate 12 or the silver-copper ion containing carrier 11 is attached to the fiber surfaces in the fibrous substrate 12 and thereby mixed together to form one layer. Of course, the silver-copper ion-containing carrier 11 may be formed by laminating the fibrous substrate 12 on top of the other. Wherein the fibrous base 12 has an individual fiber diameter of about 25 to 35 microns, preferably an individual fiber diameter of about 30 microns. In addition, the material of the fibers in the silver-copper ion-containing fiber filter layer 1 can be made of polyethylene terephthalate material.
Further, as can be seen from fig. 1, the filter element further comprises a filter sublayer 2. The filtering sublayer 2 is laminated with the silver-copper ion-containing fiber filtering layer 1. Preferably, the filter sublayer 2 and the silver-copper ion-containing fiber filter layer 1 can be connected together by means of ultrasonic welding. In terms of the air flow direction, the filter sublayer 2 is preferably located downstream of the silver-copper ion-containing fiber filter layer 1. Further, the silver-copper ion-containing fiber filter layer 1 has a hardness greater than that of the filter sublayer 2. It is understood that since the silver-copper ion-containing fiber filter layer 1 has a hardness greater than that of the filter sublayer 2, the silver-copper ion-containing fiber filter layer 1 has a certain supporting function and can be used to support the filter sublayer 2.
Wherein, the filtering sublayer 2 is a high-efficiency filtering layer, and the filtering precision of the filtering sublayer is greater than that of the filtering layer 1 containing silver-copper ion fibers. Preferably, the filter sublayer 2 can filter fine dust particles with small particle diameters, such as: the filter sublayer 2 can filter dust particles with a particle diameter of 0.3 μm, and the filtration efficiency of the layer can reach 90%.
Furthermore, the filter sublayer 2 may preferably comprise an electrostatic filter layer. The fibers in the filtering sublayer 2 are made of polypropylene material, and can also be made of polybutylene terephthalate. Preferably, the thickness of the filter element composed of the silver-copper ion-containing fiber filter layer 1 and the filter sublayer 2 can be in the range of (1.0-2.0) mm + -0.2 mm, and preferably, the thickness of the filter element is 1.5mm with a tolerance of + -0.2 mm. In addition, preferably, the two-layer filter element structure formed by the silver-copper ion-containing fiber filter layer 1 and the filter sublayer 2 is folded into a zigzag shape, so that the filtering area of the silver-copper ion-containing fiber filter layer 1 and the filter sublayer 2 can be increased, and more dust particles can be deposited and collected on the filter element structure. Thus, when the thickness of the filter element is in the above range, it is more advantageous to achieve folding of the two-layer structure into the desired shape.
The air filtration process in the case of having two filter layers of the silver-copper ion-containing fiber filter layer 1 and the filter sublayer 2 will be explained below by taking as an example a preferable positional relationship in which the filter sublayer 2 is located downstream of the silver-copper ion-containing fiber filter layer 1. First, as is known from the filtering process for air with respect to the silver-copper ion-containing fiber filter layer 1 that has been described above, when the air to be filtered passes through the silver-copper ion-containing fiber filter layer 1, the silver-copper ion-containing fiber filter layer 1 has prefiltered the fine dust of particles with larger diameters in the air, and has also sterilized and disinfected the fine dust particles in the air, so that the air filtered by the silver-copper ion-containing fiber filter layer 1 has a certain reduction in the fine dust particles, and bacteria and viruses carried in the air have been greatly reduced, even only in an amount that does not harm human health. Then, as the filtered air enters the filter sublayer 2, the filter sublayer 2 can filter the tiny-diameter dust particles in the air, and the filtering efficiency can reach 90%, so that most of the dust particles and harmful substances carried in the filtered air are filtered in the filter sublayer 2. Therefore, the air filtered by the two-layer structure of the silver-copper ion-containing fiber filter layer 1 and the filter sublayer 2 becomes cleaner.
Referring to fig. 2, the filter element of the air filter provided by the present invention may further include an activated carbon adsorption layer 3. The activated carbon adsorption layer 3 is arranged between the silver-copper ion-containing fiber filtering layer 1 and the filtering sublayer 2. Preferably, glue is sprayed on the silver-copper ion-containing fiber filter layer 1 first, then activated carbon is sprayed on the silver-copper ion-containing fiber filter layer 1, so that activated carbon is adhered to form an activated carbon adsorption layer 3, and then glue is sprayed on the activated carbon adsorption layer 3 and the filter sublayer 1 is adhered. Thereby achieving the joining of the three layers together.
Because the activated carbon adsorption layer 3 is additionally arranged between the silver-copper ion fiber filtering layer 1 and the filtering sublayer 2, the air filtered by the silver-copper ion fiber filtering layer 1 is adsorbed by the activated carbon layer on harmful substances or gas before entering the filtering sublayer 2, so that the dust particles and the harmful substances in the air can be further effectively reduced, and the activated carbon adsorption layer is particularly effective for removing peculiar smell in the air, so that the air filtered by the activated carbon adsorption layer is fresher.
In addition, can also understand that because the active carbon adsorption layer 3 sets up and contains silver-copper ion fiber filter layer 1 and filter between-layer 2, therefore the active carbon granule that has avoided existing among the prior art gets into the problem that causes secondary pollution in the carriage along with the flow of air, thereby makes the process the utility model discloses a filterable air of filter core is cleaner.
The embodiment of the utility model provides a still provide a vehicle-mounted air conditioner air cleaner, this air cleaner are provided with foretell air cleaner's filter core. Preferably, the embodiment of the present invention provides a filter element and an air filter having the same, which are particularly suitable for an air conditioner of a vehicle air conditioner to filter air entering a vehicle, the air filter can not only filter particulate matters in air like the existing filter, but also reduce or remove bacteria or viruses carried in air, which can infect and cause human diseases, by filtering and sterilizing aerosol carrying the bacteria or viruses.
