Abstract

This invention relates to a long-lasting electromagnetic field air filtration device, comprising a positively (negatively) charged electromagnetic field housing and an electromagnetic field filtration unit. The positively (negatively) charged electromagnetic field housing includes a main body and a cover plate, with an air duct inlet and an air duct outlet at both ends of the main body, and an exhaust fan at the air duct outlet. The electromagnetic field filtration unit is assembled within the main body of the aforementioned positively (negatively) charged electromagnetic field housing. The electromagnetic field filtration unit includes an outer shell and at least one positively (negatively) charged dust collection plate spaced apart and inserted within the outer shell. Sequentially, each positively (negatively) charged dust collection plate has one or more through holes on its left or right side for airflow. Furthermore, in each pair of phases... An airflow channel is formed between adjacent positively (negatively) charged dust collection plates. At least one negative (positive) ion generator can be installed at the airflow inlet of the positively (negatively) charged electromagnetic field housing or in the airflow channel. The exhaust fan generates an attractive airflow that draws air into the electromagnetic field filter unit housing through the airflow inlet of the positively (negatively) charged electromagnetic field housing. As the direction of the airflow changes, airborne particles collide with the positively (negatively) charged dust collection plates multiple times and are adsorbed. When the positively (negatively) charged dust collection plates are saturated with airborne particles, the old electromagnetic field filter unit can be removed and replaced with a new one to maintain high-efficiency air purification.

Claims

1. A long-lasting electromagnetic field air filtration device, comprising: A positively (negatively) charged electromagnetic field housing: The positively (negatively) charged electromagnetic field housing includes a main body and a cover plate. An air duct inlet and an air duct outlet are respectively provided at both ends of the main body. The cover plate is pivotally mounted in the open area at the top of the main body. An exhaust fan: Located at the air duct outlet of the main body of the electromagnetic field housing. An electromagnetic field filter unit: The electromagnetic field filter unit is assembled within the aforementioned positively (negatively) charged electromagnetic field housing. The electromagnetic field filter unit is replaceable. The electromagnetic field filter unit includes an outer shell made of non-conductive or conductive metal material and at least one positively (negatively) charged dust collection plate spaced apart and inserted into the outer shell. Sequentially, each positively (negatively) charged dust collection plate has one or more through holes on either the left or right side for airflow, thus forming an airflow channel within the outer shell. A small semi-enclosed space is formed between each pair of adjacent positively (negatively) charged dust collection plates. The electromagnetic field filter unit has a plurality of symmetrical protrusions on both sides of its outer shell. Each positively (negatively) charged dust collection plate is inserted into a slot formed by the protrusions in the outer shell of the electromagnetic field filter unit. At least one negative (positive) ion generator is provided at the air duct inlet of each electromagnetic field housing body. The negative (positive) ion generator is provided at the air duct inlet of the positively (negatively) charged electromagnetic field housing body, or at least one negative (positive) ion generator can be provided at the bottom of the electromagnetic field housing body, which passes through the outer shell of the electromagnetic field filter unit and enters between each positively (negatively) charged dust collection plate, so that the airborne particles are negatively (positively) charged. The exhaust fan generates an airflow that draws air in through the inlet of the positively (negatively) charged electromagnetic field housing. This allows airborne particles to enter the airflow channel, which is composed of at least one positively (negatively) charged dust collection plate, through the inlet of the electromagnetic field filter unit's housing. As the airflow direction changes within the airflow channel, these particles undergo Brownian motion multiple times, colliding non-directionally with the charged dust collection plates and being adsorbed. Finally, the purified air is discharged through the outlet of the electromagnetic field filter unit's housing and the outlet of the electromagnetic field housing itself. When the positively (negatively) charged dust collection plates become saturated with airborne particles, reducing air purification efficiency or eliminating its effectiveness, simply open the cover of the electromagnetic field housing, remove the old electromagnetic field filter unit, and replace it with a new one to maintain high-efficiency air purification.

2. The long-lasting electromagnetic field air filtration device as described in claim 1, wherein conductive pillars are formed at the bottom of the body of the electromagnetic field housing relative to each dust collection plate of the electromagnetic field filtration unit, so as to conduct positive (negative) electricity to each dust collection plate.

3. The long-lasting electromagnetic field air filtration device as described in claim 1, wherein the outer casing of the electromagnetic field filtration unit may be made of non-conductive material or conductive metal material.

On the other side of the cover plate and the other side of the open area of ​​the electromagnetic field housing body, a set of hooks and fasteners that can be fastened to each other are provided at corresponding positions to facilitate opening and closing of the cover plate.

5. The long-lasting electromagnetic field air filtration device as described in claim 1, wherein at least one dust collection plate can be directly inserted into one or more slots spaced apart within the electromagnetic field housing body, so that each dust collection plate is positively (negatively) charged, and a small semi-enclosed space is formed between every two adjacent positively (negatively) charged dust collection plates, constituting an airflow channel. Additionally, a non-perforated dust collection plate can be inserted into the inner surface of the electromagnetic field housing body near the airflow channel inlet and outlet. When the positively (negatively) charged dust collection plates and the non-perforated dust collection plates reach saturation from adsorbing airborne particles, causing a decrease in air purification efficiency or the absence of purification effect, simply removing the old dust collection plates and replacing them with new ones will maintain high-efficiency air purification.

6. A long-lasting electromagnetic field air filtration device, comprising: A positively (negatively) charged electromagnetic field housing: The positively (negatively) charged electromagnetic field housing includes a body and a cover plate. An air duct inlet and an air duct outlet are respectively provided at both ends of the body. One side of the cover plate and the open area side of the electromagnetic field housing body have a set of pivotable connecting parts. The two sets of connecting parts are pivotally connected together by a pivot pin, thus pivotally connecting the cover plate to the electromagnetic field housing body and allowing it to be opened and closed. On the other side of the cover plate and the corresponding position on the other side of the open area of ​​the electromagnetic field housing body, a set of hooks and fasteners that can be interlocked are provided to facilitate opening and closing the cover plate; An exhaust fan: Located at the air duct outlet of the electromagnetic field housing body; An electromagnetic field filtering unit: The electromagnetic field filtering unit is assembled within the aforementioned positively (negatively) charged electromagnetic field housing. The electromagnetic field filtering unit includes an outer shell and at least one hollow, spaced-apart small dust collection boxes (tubes) charged with positive (negative) charges, disposed within the outer shell. Each small dust collection box (tube) has one or more through holes on its corresponding two sides, on either the left or right side, for airflow. This forms an airflow channel within the outer shell of the electromagnetic field filtering unit, and further forms one or more semi-enclosed dust collection spaces within each hollow, positively (negatively) charged small dust collection box (tube). Except for the adjacent surfaces of every two dust collection boxes (tubes), the spaces formed within each dust collection box (tube) are... The dust collection space can adsorb heterogeneous air particles from multiple angles. Multiple symmetrical protrusions are provided on both sides of the outer shell of the electromagnetic field filter unit. Each positively (negatively) charged dust collection box (pipe) system is inserted into the slot formed by the protrusions in the outer shell of the electromagnetic field filter unit. At least one negative (positive) ion generator is provided at the air duct inlet of the positively (negatively) charged electromagnetic field shell. One or more negative (positive) ion generators can be provided on the electromagnetic field shell at the position corresponding to each dust collection box (pipe). Each negative (positive) ion generator is inserted into each dust collection box (pipe), so that the heterogeneous air particles flowing through each dust collection box (pipe) are negatively (positively) charged. The exhaust fan draws in negatively (positively) charged airborne particles, which then pass through the airflow channels via through-holes into one or more semi-enclosed dust collection spaces formed by the hollow positively (negatively) charged small dust collection boxes (tubes). These particles undergo multiple collisions within the spaces between adjacent surfaces of each pair of dust collection boxes (tubes). As the particles change direction during flow, they undergo Brownian motion, colliding multiple times with the inner walls of the semi-enclosed dust collection spaces and the outer walls of adjacent surfaces of each pair of dust collection boxes (tubes). Once each hollow positively (negatively) charged small dust collection box (tube) within the electromagnetic field filter unit is saturated with airborne particles, the cover of the electromagnetic field housing can be opened to replace the entire filter unit without cleaning, maintaining a high-efficiency air purification effect.

7. The long-lasting electromagnetic field air filtration device as described in claim 6, wherein each dust collection box (tube) system is constructed by bending a single sheet of material, the sheet comprising paper material and having conductive metal films bonded to both sides of the paper material, in order to enable the conductive metal films inside and outside each dust collection box (tube) to conduct positive (negative) charges, each sheet is bent so that the outer side of one end is bent and bonded to the inner side of the other end, thereby making the outer conductive metal film with positive (negative) charges contact with the inner conductive metal film, and thus making both the inner and outer conductive metal films with positive (negative) charges. In addition, conductive pillars are formed at the bottom of the body of the electromagnetic field housing relative to each dust collection box (tube) of the electromagnetic field filtration unit to conduct positive (negative) charges to each dust collection box (tube).

8. The long-lasting electromagnetic field air filtration device as described in claim 6, wherein at least one dust collection box (tube) can be directly inserted into one or more slots spaced apart within the electromagnetic field housing, so that each dust collection box (tube) is positively (negatively) charged. The suction airflow generated by the exhaust fan attracts negatively (positively) charged airborne particles into the airflow channel, and through the through holes of each dust collection box (tube), they sequentially pass through the inner wall of each hollow positively (negatively) charged small dust collection box (tube) and the outer wall of the space between adjacent surfaces of each pair of dust collection boxes (tubes), undergoing comprehensive and multiple impacts. At the same time, they are adsorbed by comprehensive Brownian motion multiple impacts in the space between adjacent surfaces of each pair of dust collection boxes (tubes). When each hollow positively (negatively) charged small dust collection box (tube) is saturated with airborne particles, a new positively (negatively) charged small dust collection box (tube) can be directly replaced without cleaning the electromagnetic field housing, so as to maintain a high-efficiency air purification effect.

9. A long-lasting electromagnetic field air filtration device, comprising: An electromagnetic field housing: Within the body of the electromagnetic field housing carrying positive (negative) charges, there is at least one positive (negative) plate with a width smaller than the body of the electromagnetic field housing and arranged in a left-right or right-facing correspondence. An S-shaped airflow channel is formed within the body of the electromagnetic field housing. At the same time, an airflow inlet is provided at one end of the electromagnetic field housing body, and an airflow outlet is provided at the other end of the electromagnetic field housing body. An open area is provided on one side of the electromagnetic field housing body. An internal dust collection duct body: The internal dust collection duct system is made of conductive metal sheet. It is located within the airflow channel of the positively (negatively) charged electromagnetic field housing and is replaceable. The shape of the internal dust collection duct body is the same as the S-shaped airflow channel system within the electromagnetic field housing. An S-shaped airflow channel is also formed in the hollow portion of the internal dust collection duct body. An airflow inlet is located at one end of the internal dust collection duct body, corresponding to the airflow inlet of the electromagnetic field housing body. An airflow outlet is located at the other end of the internal dust collection duct body, corresponding to the airflow outlet of the electromagnetic field housing body. A cover plate: Located in the open area of ​​the electromagnetic field housing body, it can be opened and closed. At least one negative (positive) ion generator: a negative (positive) ion generator is provided at the air duct inlet of the electromagnetic field housing body, and one or more negative (positive) ion generators can be provided at intervals at the bottom of the electromagnetic field housing body corresponding to the position of the inner dust collection air duct body; and an exhaust fan: provided at the air duct outlet of the electromagnetic field housing body.With the above design, after the inner dust collection duct is installed into the airflow channel of the electromagnetic field housing, all the outer surfaces of the inner dust collection duct are in full contact with the inner surface of the positively (negatively) charged electromagnetic field housing and each positively (negatively) charged plate. This allows the inner dust collection duct to also form a positively (negatively) charged electric field. When the exhaust fan at the outlet of the electromagnetic field housing duct generates an attractive airflow, air enters through the airflow inlet of the electromagnetic field housing and then through the airflow inlet of the inner dust collection duct. As the air passes through the airflow inlet of the electromagnetic field housing, it passes through the installed negative (positive) ion generator, causing the air particles to become negatively (positively) charged. These negatively (positively) charged air particles are then drawn into the inner dust collection duct by the attractive airflow from the exhaust fan, moving in a straight line. After entering the inner dust collection duct, the negatively (positively) charged air particles undergo Brownian motion within the positively (negatively) charged inner dust collection duct. The motion causes numerous high-speed collisions and rebounds between negatively (positively) charged air particles and the inner wall of the dust collection duct. As a result, a large number of these particles are gradually adsorbed onto the inner wall of the dust collection duct. Furthermore, the S-shaped airflow channel causes the negatively (positively) charged air particles to move with the airflow through the inner dust collection duct in a winding and circuitous manner. This not only prolongs the time the air particles are stationary but also continuously undergoes Brownian motion, generating numerous multi-directional high-speed collisions and rebounds. This allows the negatively (positively) charged air particles to be efficiently adsorbed into the positively (negatively) charged inner dust collection duct during this flow process. The electromagnetic field housing is designed to effectively purify the air by removing impurities from the walls. The clean air is then discharged through the outlet of the electromagnetic field housing's main duct and the outlet of the inner dust collection duct. When the inner dust collection duct becomes saturated with airborne particles, reducing its effectiveness, simply open one side of the electromagnetic field housing's cover, remove the saturated inner dust collection duct, and replace it with a new one. This allows for continuous air filtration, keeping the inner surface of the electromagnetic field housing clean and free of contaminants. This results in cost savings, easy assembly and disassembly, excellent air purification, and a significantly extended lifespan for the air filtration system.

10. The long-lasting electromagnetic field air filtration device as described in claim 9, further comprising an elongated tubular internal dust collection duct body, wherein the positively (negatively) charged electromagnetic field housing and cover plate are made into a circle, an air duct inlet is provided on the electromagnetic field housing, and an air duct outlet is provided on the longitudinal axis of the center point of the electromagnetic field housing, an exhaust fan is provided at the air duct outlet of the electromagnetic field housing, the internal dust collection duct system is made of conductive metal sheet, the internal dust collection duct body is spirally installed into the circular electromagnetic field housing, and one end of the internal dust collection duct body is assembled with At the air duct inlet of the electromagnetic field housing, the other end of the inner dust collection air duct is assembled at the air duct outlet located on the longitudinal axis of the center point of the electromagnetic field housing, thereby forming a continuous spiral air duct within the inner dust collection air duct. A negative (positive) ion generator is provided at the positive (negative) charged air duct inlet of the electromagnetic field housing, and at least one negative (positive) ion generator that can penetrate into the inner dust collection air duct can be provided at the corresponding position on the bottom surface of the electromagnetic field housing and the continuous spiral air duct within the inner dust collection air duct, so that the passing air particles become negatively (positively) charged. The suction airflow generated by the exhaust fan located at the air duct outlet of the electromagnetic field housing attracts the negatively (positively) charged air particles, which undergo Brownian motion and multiple collisions within the continuous spiral air duct formed in the inner dust collection air duct, and are thus adsorbed. When the inner dust collection air duct is saturated with adsorbed air particles, a new inner dust collection air duct can be directly replaced without cleaning the electromagnetic field housing, thus maintaining a high-efficiency air purification effect.
