Description

Technical Field

[0001] This utility model relates to the field of air purification equipment technology, and in particular to a low-energy intelligent air purification room. Background Technology

[0002] In recent years, with the acceleration of industrialization and urbanization, air pollution has become increasingly severe, and harmful substances such as PM2.5, formaldehyde, and VOCs pose a growing threat to human health. According to the "China Air Purification System Engineering Market Research Report," the Chinese air purification market is expected to maintain a compound annual growth rate (CAGR) of 15% from 2024 to 2030, with intelligent and low-energy technologies becoming the main development directions of the industry.

[0003] In industrial, medical, and residential applications, some traditional air purification systems employ mechanical fan drives and multi-layered filtration structures, but these may suffer from high energy consumption, high noise levels, and uneven airflow. Furthermore, some existing technologies still have room for improvement in airflow path control.

[0004] In existing technologies, some centrifugal fans use mechanical shaft drives, which may result in frictional losses and wear risks during long-term operation. Direct connection between the motor and impeller may cause vibration and noise problems. Some existing air duct designs are straight-cylinder or simply flared structures, leaving room for improvement in airflow organization. The lack of guiding or regulating structures affects airflow path and output volume adjustment capabilities. Some filters employ deep filtration, but their dust holding capacity and maintenance convenience still have room for improvement. Some systems support fixed fan speed adjustment but lack modular adjustment components, hindering the ease of airflow adjustment. Therefore, this utility model discloses a low-energy intelligent air-controlled air purification chamber to improve the filtration path arrangement, airflow guidance, and airflow adjustment structure of the air purification chamber.

[0030] This utility model provides, for example Figures 1 to 5 The air purification chamber shown is a low-energy intelligent air-controlled chamber, comprising: a chamber body 1, rectangular holes on both sides of the bottom of the chamber body 1, a primary filter 2 installed in each rectangular hole, a lower partition 7 and an upper partition 8 installed inside the chamber body 1, a hyperbolic air duct 9 installed in the center of the chamber body 1, an upper cover 4 installed on the top of the chamber body 1, a lower cover 5 installed on the bottom of the chamber body 1, a filter assembly inside the chamber body 1 for filtering the passing airflow; and a through circular hole in the middle of the upper cover 4 corresponding to the top of the hyperbolic air duct 9, and an adjustment assembly installed at the center of the upper end face of the upper cover 4 and around the circular hole for adjusting the airflow intensity. This solution achieves graded filtration of air pollutants by constructing a multi-stage filtration system. The primary filter 2 serves as the initial filtration unit, effectively intercepting large particulate pollutants; the secondary filter 6 further intercepts medium-sized particles; the tertiary filter 12 uses a polytetrafluoroethylene composite glass fiber membrane, which has filtration efficiency for fine particles, and the membrane material is hydrophobic, allowing for washing and reuse based on material properties. The quaternary filter 15 serves as the final purification barrier, used for final filtration of the outlet air. Furthermore, the spiral guide plate 10 and V-shaped guide ribs 13 integrated within the hyperbolic duct 9 guide the airflow entering the duct. This solution includes a permanent magnet synchronous motor 3 and a mechanical linkage adjustment component. The permanent magnet synchronous motor 3 drives the centrifugal impeller 14 to rotate. The intelligent airflow adjustment component, through a mechanical linkage structure, changes the cross-sectional area of ​​the air outlet, thereby achieving airflow adjustment. This solution guides the airflow within the duct through the cooperation of the hyperbolic duct 9, the spiral guide plate 10, and the V-shaped guide ribs 13. The V-shaped guide ribs 13 are arranged in a 60° angle array to assist the airflow in passing through the filters along a predetermined path. In addition, this air purification chamber is suitable for enclosed spaces, and its overall structure is suitable for air filtration and airflow regulation.

[0031] Furthermore, in this example, such as Figure 2 and Figure 4As shown, the filter assembly includes a secondary filter 6, which is installed at the bottom of the chamber 1. A horn-shaped air inlet 11 is installed at the lower end of the hyperbolic duct 9, with the other end of the horn-shaped air inlet 11 fitted onto the secondary filter 6. A spiral guide plate 10 is installed at the lower end of the hyperbolic duct 9. A tertiary filter 12 is installed in the middle of the hyperbolic duct 9 above the spiral guide plate 10. Multiple sets of V-shaped guide ribs 13 are installed above the tertiary filter 12 inside the hyperbolic duct 9. A centrifugal impeller 14 is installed above the V-shaped guide ribs 13 inside the hyperbolic duct 9. A permanent magnet synchronous motor 3 is installed vertically on the side wall of the chamber 1 at the position of the centrifugal impeller 14. A fourth-stage filter 15 is installed on the top inner wall of the hyperbolic duct 9. The four sides of the secondary filter 6 are snapped onto the inner wall of the chamber 1. A square groove with the same thickness as the secondary filter 6 is formed on the inner wall of the chamber 1 corresponding to the position of the secondary filter 6. The bottom of the spiral guide plate 10 is fixedly installed on the inner wall of the hyperbola duct 9, and the top of the spiral guide plate 10 is located in the middle of the hyperbola duct 9. The three-stage filter 12 is composed of polytetrafluoroethylene composite glass fiber membrane, and the conical head of the three-stage filter 12 faces the spiral guide plate 10. The V-shaped guide ribs 13 are evenly arranged in an array on the inner wall of the hyperbola duct 9, and the openings of the V-shaped guide ribs 13 face the three-stage filter 12. The V-shaped guide ribs 13 form a 60-degree angle with the inner wall of the hyperbola duct 9. The bottom of the centrifugal impeller 14 is equipped with a connecting column, and the other end of the connecting column is fixedly installed on the inner wall of the hyperbola duct 9. The centrifugal impeller 14 is installed in a snap-fit ​​rotation on the connecting column. Air enters the purification chamber from the rectangular holes at the bottom of both sides of the chamber 1. The first-stage filter 2, as the primary filtration unit, first intercepts large particulate pollutants in the air, such as dust, hair, and fibers, to prevent them from entering the subsequent purification stage, protecting the precision filter and extending its service life. Air, initially filtered by the primary filter, enters the hyperbolic duct 9 through the horn-shaped inlet 11. The secondary filter 6 is snapped into the square groove at the bottom of the chamber 1, further intercepting particulate matter such as pollen and some PM10, reducing the filtration burden on subsequent filters. At the lower end of the hyperbolic duct 9, a spiral guide plate 10 is fixed to the inner wall of the duct, guiding the airflow to form a rotating upward trajectory. Guided by the spiral guide plate 10, the airflow rises along the duct, entering the subsequent filtration area along a predetermined path. The airflow carrying unsettled particles rises to the middle of the duct, where the tertiary filter 12 (PTFE composite fiberglass membrane) intercepts the fine particles. The filter's conical head faces the spiral guide plate 10, utilizing its orientation to filter the airflow. The membrane material is hydrophobic and can be washed and reused depending on its properties. V-shaped guide ribs 13 are arranged in a 60° array in the middle of the duct, with their openings facing the tertiary filter 12. Its function is to guide the airflow through the V-shaped structure, allowing the airflow to pass through the filter. The air filtered by the three-stage filter 12 continues to rise under the drive of the centrifugal impeller 14, and undergoes final purification through the four-stage filter 15.The fourth-stage filter 15 serves as the final barrier, performing terminal filtration of the outlet air. The permanent magnet synchronous motor 3 is installed vertically at the same height as the centrifugal impeller 14 on the side wall of the chamber 1, driving the centrifugal impeller 14 to rotate.

[0032] Furthermore, in this example, such as Figure 3 and Figure 5 As shown, the adjustment assembly includes an adjustment ring 16, which is installed on the outside of a circular hole in the upper cover 4. Multiple sets of adjustable triangular plates 17 are evenly arrayed at the top of the hyperbolic duct 9, and an adjustable inverted triangular plate 18 is installed on the hyperbolic duct 9 between each set of adjustable triangular plates 17. The adjustable triangular plates 17 and the adjustable inverted triangular plates 18 are arranged adjacent to each other at intervals. A first connecting member 20 is installed on the side wall of the adjustable triangular plate 17, and a connecting rod 19 is rotatably installed on the first connecting member 20. A second connecting member 21 is rotatably installed on the other end of the connecting rod 19, and the other end of the second connecting member 21 is installed on the side wall of the adjustment ring 16. The bottom of the adjustable triangular plate 17 is flush with the hyperbolic duct 9. A first hinge is installed at the top position of the upper cover 4, and a second hinge is installed at the bottom of the adjustable inverted triangle plate 18 and the top position of the hyperbolic air duct 9. A first circular hole is opened on the connecting rod 19 corresponding to the position of the first connecting member 20, and the position of the first circular hole on the first connecting member 20 is spherical. A second circular hole is opened on the connecting rod 19 corresponding to the position of the second connecting member 21, and the position of the second circular hole on the second connecting member 21 is spherical. Both ends of the connecting rod 19 are engaged and rotatably installed with the first connecting member 20 and the second connecting member 21. An adjusting ring 16 is installed on the outside of the circular hole of the upper cover 4. The user drives the connected connecting rod 19 to move by rotating the adjusting ring 16. Both ends of the connecting rod 19 are connected to the adjustable triangle plate 17, the adjustable inverted triangle plate 18, and the adjusting ring 16 through the first connecting member 20 and the second connecting member 21, respectively. The spherical design of the first connecting member 20 and the second connecting member 21 allows the connecting rod 19 to rotate freely around them, realizing mechanical linkage. The bottoms of the adjustable triangular plate 17 and the adjustable inverted triangular plate 18 are hinged to the top of the hyperbolic duct 9 via a first hinge and a second hinge. When the adjusting ring 16 rotates, the connecting rod 19 drives the triangular plate to rotate around the hinge, changing its opening angle and thus adjusting the cross-sectional area of ​​the air outlet. By changing the opening angle of the triangular plate, the cross-sectional area of ​​the air outlet is changed, thereby adjusting the air volume. The air volume can be adjusted according to usage requirements. The adjusting components adopt a mechanical linkage structure with a clear structural relationship, facilitating installation and operation.
