Technical Field
[0001] This invention relates to the field of air purifier technology, and in particular to a high-efficiency and energy-saving air purifier. Background Technology
[0002] Air purifiers, also known as "air cleaners" or "air fresheners," are products that can adsorb, decompose, or transform various air pollutants (generally including dust, pollen, odors, bacteria, allergens, and indoor air pollution such as formaldehyde), effectively improving air cleanliness. They are mainly household and commercial air purifiers used to remove indoor air pollution.
[0003] Existing air purifiers typically employ multi-layer filtration systems, including pre-filters, HEPA filters, and activated carbon filters, to remove particulate matter, odors, and harmful gases from the air. However, existing air purifiers suffer from the following problems in practical use: First, their purification efficiency is low. The filtration system in existing air purifiers is usually fixed inside the device, resulting in a relatively simple airflow path and a limited purification range, failing to evenly purify the air throughout the room. This is especially true in large spaces, where the purification effect is often unsatisfactory. Second, their energy consumption is high. To improve purification efficiency, existing air purifiers often use high-powered fans to increase airflow, but this leads to increased energy consumption, failing to meet energy conservation and environmental protection requirements. Especially during long-term operation, high energy consumption not only increases operating costs but also places an additional burden on the environment. Therefore, this paper proposes a high-efficiency, energy-saving air purifier to address the aforementioned technical problems. Summary of the Invention
[0004] The purpose of this invention is to provide a high-efficiency and energy-saving air purifier to address the shortcomings of existing technologies and solve the technical problem of low efficiency in existing air purifiers.
[0005] To achieve the above objectives, the technical solution of the present invention is as follows:
[0006] A high-efficiency and energy-saving air purifier includes a supporting shell and a vertically arranged support column disposed inside the supporting shell. The support column is provided with an upper movable frame and a lower movable frame that can rotate around its axis. The upper and lower movable frames rotate in opposite directions and can rotate back and forth in clockwise and counterclockwise directions. The upper and lower movable frames are respectively provided with an upper movable frame and a lower movable frame that are coaxially arranged with the support column. The upper movable frame is equipped with a pair of upper filter parts arranged in opposite directions, and the lower movable frame is equipped with a pair of lower filter parts arranged in opposite directions. Both the upper and lower filter parts are used to filter the drawn air.
[0007] The top of the supporting shell is equipped with a cover and a boss placed inside the cover. An airflow channel for air circulation is formed between the inner wall of the cover and the boss. An air outlet is formed on the top of the cover. A fan module for air intake and exhaust is installed in the airflow channel. The top of the supporting shell is equipped with an annular air guide frame that is coaxial with the boss. The air guide frame is connected to the airflow channel. Several activated carbon filters for adsorbing pollutants and odors in the air are installed inside the air guide frame. The supporting shell is equipped with a first hose and a second hose. One end of the first hose is connected to the inside of the air guide frame and the other end is connected to the upper filter. One end of the second hose is connected to the inside of the air guide frame and the other end is connected to the lower filter.
[0008] The support column is equipped with a control component for controlling the upper and lower movable frames to rotate back and forth in opposite directions; it also includes a base with several vertically arranged guide columns, and the bottom of the support housing is slidably mounted on the guide columns. A first spring is wound around the guide columns and placed between the support housing and the base to apply an upward thrust to the support housing; the support housing is equipped with a pressure-applying component for intermittently applying downward pressure to the support housing to make it move downward intermittently, and is also equipped with a linkage component that drives the control component to operate when the support housing moves up and down;
[0009] The pressure-applying component includes a rotating rod arranged laterally along its axis at the bottom of the support housing. Several cams are mounted on the rotating rod, each cam having a swing end that can swing around the axis of the rotating rod. It also includes a number of fixing members, the same number as the number of cams, arranged on the top surface of the base. The fixing members are "n"-shaped and extend to the inside of the support housing. Several cams are placed inside different fixing members. The inner wall of each fixing member has a limiting groove for limiting the swing end of the cam. When the rotating rod drives the swing end of the cam to slide on the top wall inside the limiting groove, it applies downward pressure to the support housing.
[0010] Furthermore, the fan module includes a drive motor installed inside the boss with its output shaft facing upwards. The output shaft of the drive motor is coaxial with the boss. An impeller is provided in the airflow channel and is mounted on the output shaft of the drive motor.
[0011] Furthermore, both the boss and the cover have circular cross-sections; the top of the supporting shell is also provided with a protective shell for covering the cover, the top of the protective shell has an opening coaxial with the air outlet, and air guide vanes are installed at the opening.
[0012] Furthermore, the upper filter section includes a support section disposed on the upper movable frame, an installation chamber formed within the support section, and a HEPA filter screen for secondary air filtration installed in the installation chamber. The support section is also equipped with a filter cover for covering the installation chamber and performing primary air filtration. The section also includes a connecting pipe, which is positioned on the side of the HEPA filter screen away from the filter cover, with one end of the connecting pipe communicating with the installation chamber and the other end communicating with the first flexible hose.
[0013] Furthermore, the outer wall of the HEPA filter frame is formed with several grooves, and the inner wall of the mounting chamber is formed with several inserts that can be embedded in different grooves.
[0014] Furthermore, the top and bottom of the filter cover are provided with several positioning protrusions, and the top and bottom of the support are formed with several positioning grooves for the positioning protrusions to be inserted. The positioning protrusions are magnetic metal parts, and each positioning groove is equipped with a magnet for attracting the positioning protrusion.
[0015] Furthermore, the control component includes a fixed housing mounted on a support column. An upper bushing and a lower bushing are rotatably mounted on the outside of the support column. The bottom end of the upper bushing extends into the fixed housing, and a first bevel gear is mounted on the bottom end of the upper bushing. The top end of the lower bushing extends into the fixed housing, and a second bevel gear is mounted on the top end of the upper bushing. A rotating shaft with a transversely arranged axis is rotatably mounted on the fixed housing. One end of the rotating shaft extends into the fixed housing, and a third bevel gear is mounted on that end. The third bevel gear meshes with both the first and second bevel gears.
[0016] Furthermore, the linkage component includes a guide block installed at the bottom of the support housing, a lifting rod that can slide up and down on the guide block, the top end of the lifting rod extending into the support housing, the bottom end of the lifting rod extending into the outside of the support housing, a limiting block for contacting the top surface of the base installed at the bottom end of the lifting rod, a second spring wound around the lifting rod, the second spring being placed between the guide block and the limiting block to apply a downward thrust to the limiting block; a vertically arranged rack is provided on the lifting rod, and a drive gear meshing with the rack is installed on the rotating shaft.
[0017] The beneficial effects of this invention are as follows: In use, the upper and lower movable frames are controlled to rotate back and forth in opposite directions, causing them to rotate back and forth based on the axis of the support column. Furthermore, the upper and lower movable frames also rotate in opposite directions, driving a pair of upper filters and a pair of lower filters to swing back and forth around the axis of the support column. At this time, the fan module is activated, generating airflow through rotation, causing the upper and lower filters to simultaneously generate suction, drawing in indoor air and filtering it through the upper and lower filters to remove particulate matter and impurities. The filtered air then enters the air guide frame body under the transport of the first and second hoses, where it passes through an activated carbon filter to remove pollutants and odors. Finally, the air is guided through the airflow channel and blown out from the air outlet, achieving air filtration and circulation.
[0018] In addition, the upper and lower filter sections oscillate back and forth while drawing in air, which not only increases the range of air intake but also purifies the air around the air purifier more evenly, thus improving the purification effect. Furthermore, this air purifier does not increase power consumption while improving the purification effect, and it can save energy compared to existing air purifiers. Attached Figure Description

[0027] The following is a detailed description of a high-efficiency energy-saving air purifier according to the present invention, with reference to the accompanying drawings.
[0028] like Figure 1-3 As shown, an embodiment of the high-efficiency energy-saving air purifier of the present invention includes a supporting shell 1 and a vertically arranged supporting column 2 disposed inside the supporting shell 1. The supporting column 2 is provided with an upper movable frame 3 and a lower movable frame 4 that can rotate around its axis. The upper movable frame 3 and the lower movable frame 4 rotate in opposite directions and can rotate back and forth in clockwise and counterclockwise directions. When the upper movable frame 3 rotates clockwise, the lower movable frame 4 rotates counterclockwise, and when the upper movable frame 3 rotates counterclockwise, the lower movable frame 4 rotates clockwise, thereby realizing that the upper movable frame 3 and the lower movable frame 4 rotate in opposite directions when they rotate back and forth. The upper movable frame 3 is provided with an upper movable frame 31 that is annular and coaxial with the support column 2, and the lower movable frame 4 is provided with a lower movable frame 41 that is annular and coaxial with the support column 2. The upper movable frame 31 is equipped with a pair of upper filter parts 5 arranged in opposite directions, and the lower movable frame 41 is equipped with a pair of lower filter parts 6 arranged in opposite directions. Both the upper filter parts 5 and the lower filter parts 6 are used to draw in the air around the air purifier. After the air is drawn into the interior of the upper filter parts 5 and the lower filter parts 6, it is filtered and purified.
[0029] When the upper movable frame 3 and the lower movable frame 4 rotate back and forth in opposite directions, the upper movable frame 31 and the lower movable frame 41 rotate back and forth based on the axis of the support column 2. Furthermore, the upper movable frame 31 and the lower movable frame 41 also rotate in opposite directions. The upper movable frame 31 and the lower movable frame 41 respectively drive a pair of upper filter sections 5 and a pair of lower filter sections 6 to swing back and forth around the axis of the support column 2. At this time, the air purifier provides suction to the upper filter sections 5 and the lower filter sections 6. The upper filter sections 5 and the lower filter sections 6 swing while drawing in air, which not only increases the suction range but also more evenly purifies the air around the air purifier, thus improving the purification effect of the air purifier.
[0030] However, in order to provide suction for the upper filter section 5 and the lower filter section 6, a cover 9 and a boss 10 placed inside the cover 9 are installed on the top of the supporting housing 1. The cross-sections of the boss 10 and the cover 9 are both circular, and an airflow channel 11 for air flow is formed between the inner side wall of the cover 9 and the boss 10. An air outlet 14 coaxially arranged with the boss 10 is formed on the top of the cover 9. By making the cross-sections of the boss 10 and the cover 9 both circular, the resistance is reduced when the air flows in the airflow channel 11, and the airflow is more evenly dispersed. An annular air guide frame 8, coaxial with the boss 10, is also installed on the top of the supporting shell 1. The air guide frame 8 is connected to the airflow channel 11. Several annular activated carbon filters 81 are provided in the air guide frame 8 for adsorbing pollutants and odors in the air. The air first passes through the activated carbon filters 81 in the air guide frame 8 to filter out pollutants and odors in the air. After filtration, the airflow channel 11 guides the air and finally blows it out from the air outlet 14.
[0031] Furthermore, a drive motor 13 with its output shaft facing upward and coaxially arranged with the boss 10 is installed inside the boss 10. A fan wheel 12 is provided in the airflow channel 11, and the fan wheel 12 is mounted on the output shaft of the drive motor 13. A first hose 501 and a second hose 601 are also provided inside the support housing 1. One end of the first hose 501 is connected to the inside of the air guide frame 8, and the other end is connected to the upper filter section 5. One end of the second hose 601 is connected to the inside of the air guide frame 8, and the other end is connected to the lower filter section 6. Running the drive motor 13 drives the impeller 12 to rotate. The impeller 12 generates airflow through rotation, causing the upper filter section 5 and the lower filter section 6 to simultaneously generate suction, drawing in indoor air and filtering it through the upper filter section 5 and the lower filter section 6 to remove particulate matter and impurities. The filtered air then enters the air guide frame 8 under the guidance of the first hose 501 and the second hose 601, where it passes through the activated carbon filter 81 to remove pollutants and odors. Finally, the air is guided through the airflow channel 11 (e.g., ...). Figure 3As shown in the figure, air is blown out from the air outlet 14 to achieve air circulation. In addition, during the air circulation and filtration process, this air purifier controls the upper movable frame 3 and the lower movable frame 4 to rotate back and forth in opposite directions, so as to drive a pair of upper filter parts 5 and a pair of lower filter parts 6 to swing back and forth around the axis of the support column 2, thereby increasing the suction range.
[0032] Additionally, a control component 7 is installed on the support column 2 to control the upper movable frame 3 and the lower movable frame 4 to rotate back and forth in opposite directions; the air purifier also includes a base 17, which is provided with several vertically arranged guide columns 18, and the bottom of the support shell 1 is slidably mounted on the guide columns 18. A first spring 19 is wound around the guide columns 18 and is placed between the support shell 1 and the base 17 to apply an upward thrust to the support shell 1; the support shell 1 is equipped with a pressure-applying component 20 to intermittently apply downward pressure to the support shell 1 so that it intermittently moves downward, and is also equipped with a linkage component 21 that drives the control component 7 to operate when the support shell 1 moves up and down. By operating the pressure-applying component 20, downward pressure is applied to the support housing 1, causing it to move downwards. The first spring 19 is compressed, and then the pressure-applying component 20 stops applying pressure to the support housing 1. Under the action of compressing the first spring 19, the support housing 1 is pushed upwards, thereby controlling the support housing 1 to move up and down. During the movement, the linkage component 21 drives the control component 7 to operate, controlling the upper movable frame 3 and the lower movable frame 4 to rotate back and forth in opposite directions. While driving the pair of upper filter parts 5 and the pair of lower filter parts 6 to swing back and forth around the axis of the support column 2, the pair of upper filter parts 5 and the pair of lower filter parts 6 will also move up and down, further improving the range of air intake and filtration efficiency.
[0033] A protective shell 15 is also provided on the top of the supporting shell 1 to cover the cover 9. The top of the protective shell 15 has an opening coaxially arranged with the air outlet 14, and a guide vane 16 is installed at the opening. After the filtered air is discharged from the air outlet 14, the air direction is controlled by the guide vane 16 to make the air blow out in a specified direction, improving the user experience. In addition, the protective shell 15 can be rotated on the top of the supporting shell 1, so as to change the orientation of the guide vane 16 according to the user's needs to control the direction of the air blowing.
[0034] The upper filter section 5 and the lower filter section 6 have the same structure and are installed in the same way, such as Figure 4As shown, the upper filter section 5 includes a support section 51 disposed on the upper movable frame 31. An installation chamber 52 is formed in the support section 51, and a HEPA filter 53 for secondary air filtration is installed in the installation chamber 52. The HEPA filter 53 is existing technology. The HEPA filter 53 is a high-efficiency filter, mainly composed of a filter element and a frame, and is used to capture particulate dust and various suspended matter larger than 0.5μm. The support 51 is also equipped with a filter cover 56 for covering the installation chamber 52 and performing the first filtration of the air. After the HEPA filter 53 is installed inside the installation chamber 52, the filter cover 56 is installed on the support 51 to cover the installation chamber 52. During the intake process, the air first passes through the filter cover 56 for the first filtration, and then enters the installation chamber 52 and passes through the HEPA filter 53 for the second filtration. The first filtration of the air through the filter cover 56 is mainly used to capture larger particles such as dust, hair, and fibers, preventing them from entering the HEPA filter 53, reducing the burden on the HEPA filter 53, extending the service life of the HEPA filter 53, and reducing the replacement frequency and cost.
[0035] In order to stably install the HEPA filter 53 in the installation chamber 52, a number of grooves 54 are formed on the outer side wall of the frame of the HEPA filter 53, and a number of inserts 55 are formed on the inner side wall of the installation chamber 52, which can be respectively inserted into different grooves 54. During the process of installing the HEPA filter 53 in the installation chamber 52, the inserts 55 are respectively inserted into different grooves 54 to achieve stable installation of the HEPA filter 53. Furthermore, the embedded installation method makes it easy to remove the HEPA filter 53 for maintenance and repair. To facilitate the installation of the filter cover 56, several positioning protrusions 57 are provided on the top and bottom of the filter cover 56. Several positioning grooves 58 for the positioning protrusions 57 to be inserted are formed on the top and bottom of the support part 51. The positioning protrusions 57 are magnetic metal parts, and magnets 59 for attracting the positioning protrusions 57 are installed in each positioning groove 58. When installing the filter cover 56, the positioning protrusions 57 are inserted into different positioning grooves 58 respectively. At this time, the magnets 59 attract the positioning protrusions 57, thus completing the installation of the filter cover 56. The magnetic installation method is also for easy disassembly and installation. After applying sufficient external force to the filter cover 56, the positioning protrusions 57 automatically detach from the magnets 59, making it easy to clean the filter cover 56.
[0036] The upper filter section 5 also includes a connecting pipe 510. The connecting pipe 510 is placed on the side of the HEPA filter 53 away from the filter cover 56. One end of the connecting pipe 510 is connected to the mounting chamber 52, and the other end is connected to the first hose 501, thereby realizing the connection between the first hose 501 and the mounting chamber 52, so that the air is guided through the first hose 501 after passing through the first and second filters.
[0037] like Figure 5 As shown, the control component 7 includes a fixed housing 71 mounted on a support column 2. An upper bushing 72 and a lower bushing 74 are rotatably mounted on the outer side of the support column 2. The bottom end of the upper bushing 72 extends into the fixed housing 71, and a first bevel gear 73 is mounted on the bottom end of the upper bushing 72. The top end of the lower bushing 74 extends into the fixed housing 71, and a second bevel gear 75 is mounted on the top end of the upper bushing 72. A rotating shaft 76 with its axis arranged laterally is rotatably mounted on the fixed housing 71. One end of the rotating shaft 76 extends into the fixed housing 71, and a third bevel gear 77 is mounted on this end. The third bevel gear 77 meshes with both the first bevel gear 73 and the second bevel gear 75. When the rotating shaft 76 is driven to rotate, it drives the third bevel gear 77 to rotate. At this time, the first bevel gear 73 and the second bevel gear 75 rotate simultaneously in opposite directions, causing the upper bushing 72 and the lower bushing 74 to rotate in opposite directions on the support column 2. In addition, the upper movable frame 3 is mounted on the upper bushing 72, and the lower movable frame 4 is mounted on the lower bushing 74. When the upper bushing 72 and the lower bushing 74 are driven to rotate in opposite directions on the support column 2, the upper movable frame 3 and the lower movable frame 4 can be driven to rotate in opposite directions together. In order to enable the upper movable frame 3 and the lower movable frame 4 to rotate back and forth when rotating in opposite directions, the drive shaft 76 can be rotated in both directions.
[0038] Furthermore, the linkage component 21 includes a guide block 211 installed at the bottom of the support housing 1. The guide block 211 is provided with a lifting rod 212 that can slide up and down. The top end of the lifting rod 212 extends into the support housing 1, and the bottom end of the lifting rod 212 extends to the outside of the support housing 1. A limiting block 213 for contacting the top surface of the base 17 is installed at the bottom end of the lifting rod 212. A second spring 214 is wound around the lifting rod 212, and the second spring 214 is placed between the guide block 211 and the limiting block 213 to apply a downward pushing force to the limiting block 213. The operating pressure component 20 applies a downward thrust to the support housing 1 to control the downward movement of the support housing 1 on the base 17. During the movement, a thrust is applied to the limiting block 213 to push the lifting rod 212 upward on the guide block 211. At this time, the second spring 214 is compressed, and the first spring 19 is also compressed. When the pressure component 20 stops applying pressure to the support housing 1, the first spring 19 is compressed to push the support housing 1 upward on the base 17, and the upward thrust on the limiting block 213 is stopped. The second spring 214 is compressed to apply a downward thrust to the limiting block 213, causing the lifting rod 212 to move upward on the guide block 211. In addition, a vertically arranged rack 215 is provided on the lifting rod 212, and a drive gear 216 that meshes with the rack 215 is mounted on the rotating shaft 76. When the pressure application component 20 controls the support housing 1 to move up and down, it can drive the lifting rod 212 and the rack 215 to move up and down on the guide block 211, thereby driving the gear 216 to rotate forward and backward, and causing the rotating shaft 76 to rotate forward and backward, thus achieving the effect of linkage.
[0039] like Figure 6As shown, the pressure-applying component 20 includes a rotating rod 201 disposed at the bottom of the support housing 1 and arranged laterally along its axis. Several cams 202 are mounted on the rotating rod 201. Driving the rotating rod 201 to rotate causes the swing ends of the cams 202 to swing around the axis of the rotating rod 201. It also includes fixing members 203, the same number as the number of cams 202, disposed on the top surface of the base 17. The fixing members 203 are "n"-shaped, with their tops extending into the support housing 1. Several cams 202 are respectively placed inside different fixing members 203. The inner wall of each fixing member 203 is formed with a limiting groove 204 for limiting the swing ends of the cams 202. When the swing ends of the cams 202 are at the same level as the rotating rod 201, or when the swing ends are lower than the rotating rod 201, the support housing 1 is at its highest point. When the rotating rod is driven... After rotation, the cams 202 swing around the axis of the rotating rod 201. When they swing to contact the top wall of the limiting groove 204, the fixed part 203 remains stationary. Continued swinging applies downward pressure to the supporting shell 1, causing it to move downwards. When the swinging end of the cam 202 swings below the rotating rod 201, the compression of the first spring 19 pushes the supporting shell 1 upwards on the base 17. By continuously swinging the cams 202, the up-and-down movement of the supporting shell 1 can be controlled. Furthermore, the limiting groove 204 ensures that the cams 202 accurately contact the top wall of the fixed part 203 during continuous swinging, preventing deviation. A servo motor 205 is installed at the bottom inner part of the supporting shell 1. The output shaft of the servo motor 205 is connected to the end of the rotating rod 201. Running the servo motor 205 drives the rotating rod 201 to rotate.
[0040] In summary, the present invention possesses the excellent characteristics described above, which enhances its effectiveness in use compared to previous technologies, making it a highly practical product.
[0041] The above description is only a preferred embodiment of the present invention. For those skilled in the art, there will be changes in the specific implementation and application scope based on the ideas of the present invention. The content of this specification should not be construed as a limitation of the present invention.
