Electromagnetic field air purification device

Abstract

This invention relates to an electromagnetic field air purification device, comprising a positively charged electromagnetic field housing. A negative ion generator may be installed at the air duct inlet or within the electromagnetic field housing, and inside the housing itself. At least one first baffle may be distributed within the electromagnetic field housing. A baffle plate longer than the first baffle plate is installed on the air duct outlet side of the electromagnetic field housing, and a first baffle plate may also be provided. A fan is installed at the outer end of the air duct outlet. The fan draws air in, which passes through the negative ion generator, causing airborne particles to become negatively charged. Driven by the continuous airflow from the fan, the negatively charged airborne particles first enter the electromagnetic field housing in a straight line and then undergo Brownian motion within the semi-enclosed space of the electromagnetic field housing. Under the influence of the electromagnetic field, the particles undergo countless high-speed collisions and rebounds with the inner wall of the electromagnetic field housing, and are then adsorbed onto the inner wall of the electromagnetic field housing. The first baffle plate on the inner wall of the electromagnetic field housing generates obstruction and disturbance of airflow to increase the stagnation time and collision frequency of airborne particles, thereby improving the dust collection effect. At the same time, the first and second baffle plates respectively set at the air duct outlet and the air duct body block the few remaining negatively charged airborne particles at the end of the flow, causing them to be thoroughly adsorbed again, so as to discharge extremely clean air. This achieves effective adsorption and interception of airborne particles. Furthermore, the air duct outlet of the electromagnetic field housing can be connected in series with the air duct inlet of another electromagnetic field housing, which greatly improves the air purification effect.

Description

Technical Field

[0001] This invention relates to an electromagnetic field air purification device, and more particularly to an electromagnetic field air purification device that can effectively adsorb and intercept foreign particles in the air, thereby significantly improving the air purification effect. Prior Technology

[0002] Note that exhaust fumes emitted by industry and vehicles severely pollute the air, seriously affecting human health. Various invisible harmful substances or those in high concentrations float near the ground, along with harmful industrial fumes and odors. Even in still conditions, these harmful substances fall due to gravity or remain in high concentrations near the ground, tabletops, or countertops. Therefore, the concentration of polluted air is generally highest near the ground and tabletops. When we move around, the resulting airflow or natural winds will re-erase these harmful substances, causing them to disperse into the air again. Consequently, humans continuously inhale these harmful substances in various spaces, leading to various diseases.

[0003] Therefore, humans have designed various air purifiers for clean air. The electrostatic dust collection plate design of conventional air purifiers uses one or more positively (negatively) charged dust collection plates placed inside (outside) the machine casing to adsorb negatively (positively) charged air particles passing by, thereby achieving the air filtration function. Negatively (positively) charged air particles can only be adsorbed when they are very close to the positively (negatively) charged dust collection plates or in a very slow-moving airflow.

[0004] As is known, air purifiers draw in air and quickly expel it through a straight air passage from the outlet. Therefore, in many cases, due to the large and fast airflow of negatively (positively) charged air particles and the positively (negatively) charged dust collection plates, and because the air particles travel in a straight line, some of these particles can easily escape the positive (negative) attraction of the dust collection plates and leave with the airflow. Consequently, the filtration quality is not ideal. Most commonly used filters can only filter particles as small as 0.1μm. Therefore, due to their poor filtration performance, the filters of most commercially available air purifiers only need cleaning after several months of use. This phenomenon does not indicate good air quality, but rather reflects the poor filtration effect.

[0005] Furthermore, this invention is a further improvement upon the applicant's previous patent applications, U.S. Patent No. 8,268,058 and Republic of China Patent No. 1376488. The previously filed patent technology has thoroughly solved the problem of poor filtration effect of conventional air purifiers. However, due to the high cost, the inventor hopes to design a low-cost, easy-to-disassemble and replace, highly efficient and low-energy-consumption design without changing the high-efficiency filtration effect of the previously filed patent, so that it can be more widely used to maintain the air quality of various spaces. Summary of the Invention

[0006] <The technical problem to be solved> In view of the aforementioned practical difficulties and shortcomings of conventional designs, the inventors hoped to provide a breakthrough design to improve practical effects. Therefore, they devoted themselves to research, design and construction, and combined their professional technical knowledge and practical experience in the design, production and sales of related products over many years with the results of their research and design to finally develop an electromagnetic field air purification device for users.

[0007] <Technical Means of Problem Solving> This invention relates to an electromagnetic field air purification device, comprising a positively charged electromagnetic field housing. A negative ion generator may be installed at the air duct inlet or within the electromagnetic field housing, and at least one first baffle may be distributed within the electromagnetic field housing. A first baffle may be installed at the air duct outlet of the electromagnetic field housing. A fan is installed at the outer end of the air duct outlet. Air is drawn in by the fan and passes through the negative ion generator, causing airborne particles to become negatively charged. Driven by the continuous airflow from the fan, the negatively charged airborne particles initially enter the electromagnetic field housing in a straight line. The negatively charged airborne particles then undergo Brownian motion within the semi-enclosed space of the electromagnetic field housing. Under the influence of the electromagnetic field, the particles undergo countless high-speed collisions and rebounds with the inner wall of the electromagnetic field housing. They are then attracted to the inner wall of the electromagnetic field housing by the positively charged electromagnetic field housing. At least one first baffle on the inner wall of the electromagnetic field housing generates obstruction and disturbance of airflow to increase the stagnation time and collision frequency of airborne particles, thereby improving the dust collection effect. At the same time, the first baffle at the air duct outlet blocks the few remaining negatively charged airborne particles carried by the airflow to the end, causing them to return and collide with the inner wall of the electromagnetic field housing again for thorough adsorption. The second baffle then intercepts the airborne particles, causing them to undergo high-speed collisions and be adsorbed again. The extremely clean air is finally discharged through the holes of the second baffle, effectively adsorbing and intercepting airborne particles and greatly improving the air purification effect.

[0008] <Comparison with the effectiveness of previous technologies> The main objective of this invention is to design the air duct inlet and outlet to be linear or non-linear with the electromagnetic field shell, so that negatively charged air particles in the intake air undergo countless high-speed collisions and rebounds with the inner wall of the electromagnetic field shell under Brownian motion in the semi-enclosed space within the shell. They are then attracted to the inner wall of the electromagnetic field shell by the positively charged electromagnetic field shell. Furthermore, the air to be discharged at the end also needs to undergo collisions before it can be discharged, greatly increasing the probability of air particles being adsorbed.

[0009] A second objective of this invention is that, as needed, at least one first baffle can be provided on the inner wall of the electromagnetic field housing to generate obstruction and disturbance of airflow, thereby increasing the stagnation time and collision frequency of heterogeneous air particles and improving dust collection efficiency. At the same time, the first baffle provided at the air duct outlet can block the few remaining negatively charged heterogeneous air particles carried by the airflow to the end again, causing them to collide with the inner wall of the electromagnetic field housing and be thoroughly adsorbed.

[0010] Another objective of this invention is to utilize a second baffle installed inside the air duct at the outlet of the air duct to further obstruct and intercept airborne particles, causing them to undergo ultra-high-speed collisions and be re-adsorbed. The extremely clean air is then discharged through the holes of the second baffle, effectively adsorbing and intercepting airborne particles and significantly improving the air purification effect.

[0013] Please refer to Figures 1 and 2. This invention relates to an electromagnetic field air purification device, which includes a positively charged electromagnetic field housing 1. At least one air duct inlet 11 is provided on one side of the electromagnetic field housing 1, and a negative ion generator 13 may be provided inside the electromagnetic field housing 1. At least one first baffle 15 may be distributed inside the electromagnetic field housing 1. At least one air duct outlet 12 is provided on the other side of the electromagnetic field housing 1. A baffle 14 may be provided on one side of the air duct outlet 12 to prevent airflow from directly impacting the air duct outlet 12. A first baffle 16 may also be provided at the air duct outlet 12. A fan 3 is provided at the outer end of the air duct outlet 12. A gap 161 or hole is formed at the periphery between the first baffle 16 and the air duct outlet 12. Air 2 is drawn in by the fan 3 and passes through the negative ion generator 13, causing the air particles to become negatively charged. The negatively charged air particles, driven by the continuous airflow drawn in by the fan 3, first enter the electromagnetic field housing 1 in a straight line. Inside, negatively charged air particles in the continuously drawn-in airflow will undergo countless ultra-high-speed collisions and rebounds with the inner wall of the electromagnetic field housing 1 under Brownian motion within the semi-enclosed space. Each ultra-high-speed collision and the attraction of the positively charged electromagnetic field housing 1 (opposites attract) causes the negatively charged air particles to be rapidly adsorbed onto the inner wall of the electromagnetic field housing 1. Furthermore, one or more first baffles 15 can be installed on the inner wall of the electromagnetic field housing 1 to obstruct and turbulent the airflow, increasing the time the negatively charged air particles remain within the electromagnetic field housing 1 and increasing the number of collisions, thereby improving the dust collection effect. Simultaneously, the dust is collected through the air outlet 12... The first baffle 16 will block the few remaining negatively charged air particles carried by the airflow to the end, causing them to collide with the inner wall of the electromagnetic field housing 1 and be thoroughly adsorbed again. The airflow will then flow out through the gap 161 between the first baffle 16 and the air duct outlet 12. Furthermore, the design of the air duct inlet 11 and the air duct outlet 12 of this invention, which are both linear or non-linear with the electromagnetic field housing 1, along with the addition of blocking and turbulence design, effectively blocks the negatively charged air particles after they enter and greatly increases the probability of them colliding with the inner wall of the electromagnetic field housing 1. This effectively adsorbs and intercepts air particles, greatly improving the air purification effect.

[0014] The air duct inlet 11 of the present invention can be at least one or more (as shown in the third figure). Through the design of the present invention, the air duct outlets 12 of more than one electromagnetic field housing 1 can be serially connected to the air duct inlet 11 of another electromagnetic field housing 1 to achieve multiple collisions and adsorption of air heterogeneous particles, achieving an excellent air microdust filtration effect (as shown in the fourth figure). In addition, in the electromagnetic field housing 1 of the present invention, in addition to the first spoiler 15 shown in the first figure, at least one second spoiler 151 in the shape of a "mouth" can also be provided. The second spoiler 151 has spoiler parts 1511 around its perimeter and only a channel opening 1512 for air to pass through in the center (as shown in the fifth and sixth figures). Through the second spoiler 151, the air heterogeneous particles passing through are also made to increase the effects of turbulence, blocking, and collision, and increase the frequency of collision to improve the air purification effect.

[0015] In addition to the air duct body 111 provided at the air duct inlet 1 of the present invention (as shown in the first, second, and fifth figures), at least one air inlet 112 for the air 2 airflow can also be directly provided in the electromagnetic field housing 1 without providing the air duct body 111, and the negative ion generator 13 can be provided at or inside the air inlet 112 (as shown in the seventh and eighth figures).

[0016] In addition, a second baffle 17 can be provided in the air duct body 121 of the air duct outlet 12 of the present invention. At least one hole 171 for air to pass through is distributed on the second baffle 17. When the air airflow is attracted by the continuous suction of the fan 3 and enters the air duct body 121 of the air duct outlet 12 through the gap 161 between the peripheries of the first baffle 16, it will pass through the blocking of the second baffle 17, causing only extremely few air heterogeneous particles to generate ultra-high-speed collisions and be adsorbed by the inner wall of the air duct body 121 with the same positive charge. The final clean air is then discharged through the holes 171 of the second baffle 17 (as shown in the ninth and tenth figures).

[0017] The aforementioned first spoiler 15 and second spoiler 151 can be provided or not provided as required. In addition, the first baffle 16 and second baffle 17 can also be provided or not provided as required.

[0018] The electromagnetic field housing 1 can also be negatively charged, and a positive ion generator (not shown in the figure) can be provided at the air duct inlet 11 to make the air heterogeneous particles positively charged.

[0019] This invention can be used as a main component of an air filtration and purification device. It can be designed to be easily disassembled and replaced. After a period of use, once the adsorbed airborne particles are saturated, it can be disassembled and replaced. It has the characteristics of high efficiency, low energy consumption and sterilization and disinfection. It can be widely used for dust purification in homes, public places, hospitals, clinics, factories and integrated circuit manufacturing and packaging plants.

It meets the requirements for granting an invention patent, and therefore, this patent application is filed in accordance with the law. We respectfully request that the esteemed examiner carefully examine the application and grant the patent as soon as possible, which would be of great benefit.
