Description

Technical Field

[0001] The present invention relates to the technical field of air purifier devices, and particularly to an air purifier and an air purification method. Background Art

[0002] An air purifier, also known as an air cleaner or air freshener, refers to a product that can adsorb, decompose or transform various air pollutants, generally including dust, pollen, odors, bacteria, allergens, and indoor air pollution such as formaldehyde from decoration. It can effectively improve the air cleanliness. The main types are household and commercial air purifiers for removing indoor air pollution. Air purifiers usually adopt a combination of passive and active purification methods. The motor makes the indoor air circulate. The polluted air passes through the air filter in the machine to remove or adsorb various pollutants. After passing through the negative ion generator, the air is ionized to generate negative ions, which are sent out by the gentle breeze to form a negative ion air flow, achieving the purpose of cleaning and purifying the air. Its main components include a cabinet shell, a filtration section, a duct design, a motor, a power supply, a liquid crystal display, etc. The main technologies include activated carbon adsorption technology, ion filtration technology, ozone sterilization technology, high-efficiency air filters, etc. Air purifiers are used in the fields of home, medical, and industry. In the home field, single-unit household air purifiers are the mainstream products in the market. The most important function is to remove particulate matter in the air, including allergens, indoor PM2.5, etc. At the same time, it can also solve the problem of air pollution caused by volatile organic compounds in indoor, underground spaces, and cars due to decoration or other reasons. Since the release of air pollutants in relatively enclosed spaces has the characteristics of persistence and uncertainty, using an air purifier to purify indoor air is one of the internationally recognized methods to improve indoor air quality.

[0003] For example, the patent document with the publication number CN 106352530 B discloses an air purifier and an air purification method. The air purifier includes: an air inlet, an air outlet, an activated carbon cavity, an air pump, and a water container; a microdust isolation grid is provided at the air inlet, and the microdust isolation grid is used to filter solid particles. The activated carbon cavity filled with activated carbon is connected to the air inlet, and the activated carbon is used to filter the air entering from the air inlet. The air pump is connected to the activated carbon cavity through a first conduit and connected to the water container through a second conduit. The air pump is used to introduce the air passing through the activated carbon cavity into the water container through the second conduit. A first adjustable container is provided in the water container, which is used to hold sodium percarbonate. Sodium percarbonate is used to chemically react with the water in the water container to purify the air introduced by the air pump, and the air is discharged from the air outlet. Through the embodiments of the present invention, the functions of the air purifier can be enriched and the user experience can be improved.

[0004] However, during the actual use of this structure, due to the limitations of its own structure, it can often only perform the single-filter ventilation and air filtration operation of the air purifier. Its ventilation volume is severely restricted by the flux of a single filter element, resulting in a serious limitation of the maximum ventilation volume of the air purifier. Therefore, it cannot meet the more efficient filtration and treatment operations of daily air under high pollution conditions. At the same time, the device cannot perform efficient replacement and maintenance of the air purifier filter element. During subsequent use, it cannot perform efficient internal maintenance and cleaning operations, nor can it perform rapid height adjustment of the entire air purifier, failing to meet the daily use requirements. Therefore, there is an urgent need to design an air purifier and an air purification method to solve the above problems. Summary of the Invention

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] This air purifier and air purification method can enable the air purifier device to perform more efficient large-throughput air purification operations. During actual use, the filter arc net on the side of the arc-shaped outer cover can be adaptively covered at the ventilation side grille on the side of the purification rack to provide annular covering protection for the air inlet position. After the air inlet unit inside the air suction fan cover starts, it can perform uniform annular filtering and air suction operations from the ventilation side grille on the side of the purification rack. The cross-shaped air filter rack inside the purification rack cooperates with the filter element bodies on the four sides to perform synchronous and efficient air filtering operations. The filtered air can be collected at the air collection grille on the inner wall of the air collection pipe, and then is transported upward to perform synchronous high-throughput continuous air filtering operations. By starting the air outlet grille and air outlet unit inside the air outlet net cover, efficient air flow operations can be achieved. The air outlet grille evenly diffuses the filtered air flow on the side of the air outlet net cover, thereby greatly improving the filtering efficiency of the device for the surrounding air, enabling the device to meet the large-throughput air filtering operations in daily high-pollution environments, and reflecting the practicality of the device design.

[0020] The air purifier and the air purification method can further improve the overall use effect of the equipment.

Then, the upper and lower parts of the purification frame are quickly moved out between the lower ventilation cone cover and the upper ventilation cone cover, and then the overall cross-shaped air filter frame inside is cleaned and maintained. And when the telescopic airbag and telescopic top plate drive the purification frame to reset between the lower ventilation cone cover and the upper ventilation cone cover, the sealing rings at the upper and lower ends of the purification frame and the first sealing ring at one end of the lower ventilation cone cover and the upper ventilation cone cover can be hermetically fitted, so as to ensure the sealing performance at the upper and lower ends of the overall purification frame during daily ventilation and filtration use. Start the electric push rod inside the fixed back frame to carry out stable adjustment operation for air purification at different heights that is more suitable for the overall equipment, reflecting the comprehensiveness of the equipment design.

[0036] Working principle: When in use, the user first installs the entire cross-shaped air filter rack 3 to be used inside the purification rack 1. Then, the arc-shaped outer cover 12 opens in an arc and is sleeved and installed on the side of the purification rack 1. The first magnetic attraction strips 26 at both ends of the arc-shaped outer cover 12 can be adaptively docked at the second magnetic attraction strips 41 on both sides of the back connection seat 40 for magnetic attraction tightening operation. At this time, the filter arc net 25 on the side of the arc-shaped outer cover 12 can be adaptively sleeved on the ventilation side grille 2 on the side of the purification rack 1 for annular covering protection of the air intake position. When the air intake unit 31 inside the air suction fan cover 11 at the bottom of the device starts, uniform annular filtered air suction operation can be carried out from the ventilation side grille 2 on the side of the purification rack 1. The air flow converges through the lower ventilation cone cover 35 and passes through the lower ventilation seat 33 and enters the air suction fan cover 11. At this time, the air suction fan cover 11 can send the air flow evenly from the air intake hole slots 30 on the side of the air intake cover 29 through the annular air distribution rack 28 on the inner wall in a circular shape, and then send it into the interior of the purification rack 1 from the ventilation hole slots 32 at the top of the air intake unit 31. At this time, the cross-shaped air filter rack 3 inside the purification rack 1 cooperates with the filter element bodies 4 on the four sides to perform synchronous and efficient air filtering operation. The filtered air can be collected at the air collection grille 6 on the inner wall of the air collection pipe 5, and then conveyed upward for synchronous high-throughput continuous air filtering treatment operation. Finally, the filtered air flow passes through the air collection grille 6 on the top of the purification rack 1, passes through the upper ventilation seat 34, and converges into the interior of the air outlet net cover 10. At the same time, the device can start the air outlet grille 44 and the air outlet unit 45 inside the air outlet net cover 10 to achieve efficient air flow operation. The air outlet grille 44 evenly diffuses the filtered air flow on the side of the air outlet net cover 10, thereby greatly improving the air filtering efficiency of the device for the surrounding air, enabling the device to meet the large-throughput air filtering operation in a daily high-pollution environment. During daily use, the staff can start the air control pump 22 on the side of the retractable cover 13 to control the inflation and deflation of the internal expansion airbag 23 and the expansion top plate 24. That is, under the limitation of the limit groove 42 and the limit inner pad 43 in the limit frame 7, it performs telescopic adjustment operation to quickly adjust the entire purification rack 1. Thus, the purification rack 1 can be quickly moved up and down out of the space between the lower ventilation cone cover 35 and the upper ventilation cone cover 36, and then the entire cross-shaped air filter rack 3 inside it can be cleaned and maintained. And when the expansion airbag 23 and the expansion top plate 24 drive the purification rack 1 to reset between the lower ventilation cone cover 35 and the upper ventilation cone cover 36, the sealing ring seats 38 and the second sealing rings 39 at the upper and lower ends of the purification rack 1 can be hermetically fitted with the first sealing rings 37 at one end of the lower ventilation cone cover 35 and the upper ventilation cone cover 36, so as to ensure the sealing performance at the upper and lower ends of the entire purification rack 1 during daily ventilation and filtering use. At the same time, the electric push rod 15 inside the fixed back rack 14 can be started daily to drive the entire purification rack 1 to perform lifting adjustment operation on the surface of the support base 16.The second docking pad 20 at the bottom end of the electric push rod 15 is fitted and docked with the second docking seat 21, and the first docking pad 19 at the bottom end of the suction fan cover 11 can also be docked with the first docking seat 18 at one end of the surface of the support base 16 to perform stable adjustment operations for air purification at different heights that are more suitable for the overall equipment. The above is the entire working principle of the present invention.

At this time, the suction fan cover (11) evenly sends the airflow from the air inlet slot (30) on the side of the air inlet cover (29) through the annular air uniforming frame (28) on the inner wall, and then sends it into the interior of the purification frame (1) from the ventilation slot (32) at the top of the air inlet unit (31). The filtered air is collected at the air collection grille (6) on the inner wall of the air collection pipe (5), and then transported upward. Finally, the filtered airflow follows the air collection grille (6) on the top of the purification frame (1), passes through the upper ventilation seat (34), and is collected in the interior of the air outlet mesh cover (10); S2, start the air control pump (22) on the side of the shrink cover (13) to control the inflation and deflation of the internal telescopic airbag (23) and the telescopic top plate (24), so that the telescopic airbag (23) and the telescopic top plate (24) are telescopically adjusted under the limit of the internal limit groove (42) and the limit inner pad (43) of the limit frame (7), and the purification rack (1) is quickly adjusted to move upward and downward, so that the purification rack (1) is quickly moved out from between the lower ventilation cone cover (35) and the upper ventilation cone cover (36), and when the telescopic airbag (23) and the telescopic top plate (24) bring the purification rack (1) back to between the lower ventilation cone cover (35) and the upper ventilation cone cover (36), the sealing ring seat (38) and the second sealing ring (39) at the upper and lower ends of the purification rack (1) are sealed and fitted with the first sealing ring (37) at one end of the lower ventilation cone cover (35) and the upper ventilation cone cover (36).
