Comprises an outer frame 100 and a combined filtering structure 200: the combined filter structure 200 is provided with a plurality of pairs of electrostatic filter screens 210 of high-voltage electrode pairs 217, the outer frame 100 is integrally formed with the outer frame 100, the combined filter structure 200 is arranged in the outer frame 100, when air passes through the high-voltage electrode pairs 217, bacteria and viruses in the air are broken down by the voltage of the high-voltage electrode pairs 217, and dust in the air is adsorbed by the electrodes of the high-voltage electrode pairs 217. Has the functions of dust removal, sterilization and disinfection. The simple electrode pair 217 reduces wind resistance and performs multiple functions.
In order to better understand the above technical solutions, the following detailed description will refer to the accompanying drawings and specific embodiments.
An air purifying, sterilizing and filtering system, as shown in fig. 1, includes an outer frame 100 and a combined filtering structure 200: the combined filter structure 200 is an electrostatic filter screen 210 provided with a plurality of pairs of high-voltage electrode pairs 217, the outer frame 100 is an integrally formed outer frame 100, the combined filter structure 200 is arranged in the outer frame 100, when air passes through the high-voltage electrode pairs 217, bacteria in the air are broken down by the electric field of the high-voltage electrode pairs 217, and dust in the air is adsorbed by the electrodes of the high-voltage electrode pairs 217.
Wherein, the electrode pair 217 is sheet-shaped, effectively reduces the windage of air to reduce the energy consumption.
Also included is a high voltage package 300 and a positive charge releaser and a negative charge releaser connected to the high voltage package 300. Specifically, the electrostatic screen 210 communicates with the electrostatic screen electrode 211, and the electrostatic screen electrode 211 communicates with the high-voltage package 300.
Specifically, the air inlet and the air outlet are also included; the air inlet is located at one end of the combined filter structure 200; the air outlet is located at the other end of the combined filter structure 200, remote from the air inlet.
When in use, air continuously enters the high-voltage electrode pair 217 of the electrostatic filter screen 210 from the air inlet, bacteria and viruses in the air are broken down by an electric field between the high-voltage electrode pair 217, and the bacteria and viruses in the air are killed. The sterilization of bacteria and viruses in the air can be completed without a multi-layer complex filtering sterilization structure and without obviously reducing wind resistance. The air purifying, sterilizing and filtering system can be applied to indoor air conditioners and automobile air conditioners. The internal circulation mode of the air conditioner is started, and the internal circulation air continuously completes the sterilization of bacteria and viruses in the electrostatic filter screen 210. At the same time, the adsorption of dust in the air by the electrodes of the high-voltage electrode pair 217 corresponds to the realization of the dust removal function.
In order to improve the safety of the air purification, disinfection and filtration system, as shown in fig. 2, the high-voltage electrode pair 217 consists of a plurality of parallel electrode strips 215, and the electrode strips 215 consist of an upper insulating layer 212, a lower insulating layer 212 and a metal film 213 positioned between the insulating layers 212; each high-voltage electrode pair 217 is composed of 2 electrode strips 215 respectively connecting the positive and negative electrodes.
Specifically, the high-voltage electrode pair 217 is composed of a plurality of parallel electrode strips 215, and the electrode strips 215 are composed of upper and lower PET film insulating layers 212 and an aluminum film between the PET film insulating layers 212. After the electrode strip 215 is coated with the insulating layer 212, electric leakage is not easily caused. After the insulating layer 212 is coated on the positive and negative electrode strips 215, an electric field is still generated between the positive and negative electrode strips 215. When air passes through the high-voltage electrode pair 217, bacteria in the air are broken down by the electric field of the high-voltage electrode pair 217, and dust in the air is adsorbed by the electrodes of the high-voltage electrode pair 217. The internal circulation mode of the air conditioner is started, and the internal circulation air continuously completes the sterilization of bacteria and viruses in the electrostatic filter screen 210. Generally, the disinfection and purification process can be completed within about 1 hour.
Dust in the air is generally positively charged, and when entering between the high-voltage electrode pair 217, the dust migrates along the electric field direction toward the negatively charged negative electrode strip 215 and adheres to one end of the negative electrode strip 215. In order to further increase the efficiency of dust adsorption, the positive charge imparted to the dust in the air is enhanced. A positive charge releaser is provided at the air inlet to impart positive charge to dust in the air that is about to enter between the high voltage electrode pairs 217.
Specifically, the positive charge releaser and the negative charge releaser are carbon brushes 221, and the carbon brushes 221 are divided into positive charge carbon brushes 221 and negative charge carbon brushes 221. The carbon brush circuit 220 is also in communication with the high voltage package 300. The carbon brushes 221 are disposed on the carbon brush circuit 220, which is distributed around the high-voltage electrode pairs 217.
Specifically, the outer frame 100 reserves a recess space for accommodating a main portion of the carbon brush 221 to protect the carbon brush 221 from being easily affected by external force.
Specifically, the electrostatic net electrode 211, the electrode belt 215, the carbon brush circuit 220 and the high-voltage package 300 are hidden inside the outer frame 100, so as to avoid the damage caused by external contact.
The air purifying, sterilizing and filtering system of the embodiment can be applied to household air conditioners, public place air conditioners and automobile air conditioners. The air purifying, disinfecting and filtering system of the embodiment does not use an organ-shaped filter screen or a multi-layer filter screen, so that wind resistance and energy consumption of a fan, which is required by overcoming the wind resistance, are reduced. The excessive dust stays in the organ-shaped filter screen and the multi-layer filter screen in the prior art, and although the dust at the air outlet can be reduced, bacteria carried by the collected dust can be continuously propagated, more bacteria are bred, and the improvement of air quality is not facilitated. The air purification, sterilization and filtration system of the embodiment has low wind resistance, and sterilization is completed in the dust adsorption process, so that the air quality is effectively improved.
Graphene is a hot new material, and the carbon brush 221 can be made of a graphene material or a graphene carbon rod is used for replacing the carbon brush 221.
To avoid damage to the combined filter structure 200 caused by large particles or debris entering the electrostatic filter screen 210, a pre-filter screen, preferably 1-2mm thick, is installed at the air inlet to reduce wind resistance.
In operation, a strong electric field is formed between the high-voltage electrode pair 217, which applies a great attractive force to charged particles moving in the air, and can adsorb almost all moving particles flowing through the high-voltage electrode pair while generating minimum airflow resistance, so that the high-voltage electrode pair has remarkable effect of removing particulate pollutants such as PM 2.5. Meanwhile, bacteria, microorganisms, etc. attached to the particulate matter can be collected and killed in a strong electric field. The high voltage electrode pair 217 has high efficiency in removing PM2.5 and also has high efficiency in sterilizing.
Dust in the air floats up to be unfavorable for the health of people, and the adsorption by the negative electrode belt 215 alone is not necessarily capable of meeting the dust removal effect for a long time. In order to reduce the amount of floating dust in the air, it is necessary to let the floating dust in the air drop downward so as not to float in the air. Accordingly, positive charge releasers and negative charge releasers are provided at the air inlet and the air outlet, respectively. Carbon brushes 221 are preferable as positive charge releasers as well as negative charge releasers, i.e., positive charge carbon brushes 221 and negative charge carbon brushes 221. The positively charged carbon brush 221 and the negatively charged carbon brush 221 communicate with the high-voltage package 300 through the carbon brush electrode 223.
When dust-containing air enters the air inlet, the positive-charge carbon brush 221 endows dust with positive charge, and when the dust with positive charge passes between the electrode pairs 217, bacteria or viruses carried by the dust are broken down and killed by an electric field, and the dust with positive charge is adsorbed by one end of the negative electrode.
Negative charge carbon brush 221 sets up in the air outlet, lets the anion that negative charge carbon brush 221 produced blow to in the air from the air outlet, and the positive charge is taken to some dust in the air is mainly, and the back is contacted with neutral dust to the negative charge dust, and negative charge dust and positive charge dust attract each other, and when negative charge dust and positive charge dust gathering are more and more, its weight improves to fall to the ground direction, thereby reduce the quantity of dust in the air. In general, the dust in the air can be effectively reduced by more than 80% of the quantity of floating dust in the air after the air purifying, sterilizing and filtering system is started for about one hour.
The utility model is applied to a high-efficiency virus-killing and purifying automobile air conditioner filter, and belongs to the technical field of air purification. The electric charge applying device comprises an outer frame 100, an electric charge applying device 150 and a combined filter structure 200, wherein the combined filter structure 200 is provided with a plurality of pairs of high-voltage electrodes 217, the outer frame 100 is integrally formed into the outer frame 100, and the combined filter assembly 200 is arranged in the outer frame 100; the periphery of the combined filter structure 200 is provided with a negative ion imparting device serving as a charge imparting device 150, bacteria and dust in the air are imparted with negative charges by a negative ion emission carbon brush before entering the combined filter structure 200, and the bacteria and dust with negative charges in the air are rapidly adhered to the dust with positive charges so as to enlarge and weight dust particles, enter a preset high-voltage electric field of 4-8 kilovolts, and are rapidly carbonized and killed by the high-voltage electric field; dust is adsorbed by the high-voltage electrode and falls off.
Specifically, as shown in fig. 3-4, the high voltage package 300 is electrically connected to the charge imparting device 150 and the electrode pair 217, respectively. The high voltage package 300 is externally connected to the power outlet 500. The carbon brush 221 is electrically connected to the high-voltage package 300 through a carbon brush circuit 220 including a carbon brush electrode 223. To further enhance the sterilizing filtering effect, a nickel screen is added between the combined filtering structure 200 and the upper and lower frames, and a sterilizing agent is coated on the nickel screen. The wind resistance of the whole combined filtering structure is extremely low and is about 10% of that of a traditional air conditioner filter; the dust filtering efficiency is 10 times of that of the traditional air conditioner filter; meanwhile, the coexistence of sterilization and disinfection man-machine can be realized. The utility model effectively solves the pain point of the automobile interior due to narrow space and extremely poor air quality of human multi-bacteria virus, and effectively improves the air quality in the automobile and prevents infectious diseases.
As shown in fig. 4 to 5, the embodiment using 3 carbon brush electrodes 223 is optimal.
