Description

Technical Field

[0002] Air purifier, also known as "air cleaner" or air refresher, refers to a product that can absorb, decompose or transform various air pollutants (generally including dust, pollen, odor, bacteria, allergens and decoration pollution such as formaldehyde, etc.), effectively improving the cleanliness of the air. It mainly includes household and commercial air purifiers that remove indoor air pollution.

[0003] Existing air purifiers usually use a multi-layer filtration system, including a primary filter, a HEPA filter, an activated carbon filter, etc., to remove particulate matter, odors and harmful gases in the air. However, the existing air purifiers have the following problems in actual use: First, the purification efficiency is not high. The filtration system of the existing air purifier is usually fixed inside the equipment, and the path of air passing through the filter is relatively single, resulting in a limited range of air purification and the inability to evenly purify the air in the entire room. Especially in large spaces, the purification effect of air purifiers is often unsatisfactory; second, the energy consumption is high. In order to improve the purification efficiency, existing air purifiers usually use high-power fans to increase the air flow rate, but this will lead to increased energy consumption and does not meet the requirements of energy conservation and environmental protection.

[0027] The following is a detailed description of an energy-efficient air purifier of the present invention with reference to the accompanying drawings.

[0028] like Figure 1-3 As shown, an embodiment of a high-efficiency energy-saving air purifier of the present invention includes a supporting shell 1 and a supporting column 2 disposed in the supporting shell 1 and arranged vertically, the supporting column 2 is provided with an upper movable frame 3 and a lower movable frame 4 which can rotate around its axis, the upper movable frame 3 and the lower movable frame 4 rotate in opposite directions, and both can rotate back and forth clockwise and counterclockwise; 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 achieving that the upper movable frame 3 and the lower movable frame 4 rotate in opposite directions when they rotate back and forth. Among them, the upper movable frame 3 is provided with an upper movable frame 31 which is annular and coaxially arranged with the support column 2, and the lower movable frame 4 is provided with a lower movable frame 41 which is annular and coaxially arranged 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. The upper filter parts 5 and the lower filter parts 6 are both used to absorb the air around the air purifier, and after being absorbed into the upper filter parts 5 and the lower filter parts 6, the air is filtered and purified.

[0029] When the upper movable frame 3 and the lower movable frame 4 are controlled to 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, and 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 parts 5 and a pair of lower filter parts 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 part 5 and the lower filter part 6, and the upper filter part 5 and the lower filter part 6 swing while absorbing air, which not only increases the absorption range, but also can more evenly purify the air around the air purifier, thereby improving the purification effect of the air purifier.

[0030] However, in order to provide suction force for the upper filter part 5 and the lower filter part 6 to absorb air, a cover body 9 and a boss 10 placed inside the cover body 9 are installed on the top of the supporting shell 1. The cross-sections of the boss 10 and the cover body 9 are both circular, and an air flow channel 11 for air flow is formed between the inner wall of the cover body 9 and the boss 10. An air outlet 14 coaxially arranged with the boss 10 is formed on the top of the cover body 9. By making the cross-sections of the boss 10 and the cover body 9 both circular, the resistance of the air when flowing in the air flow channel 11 is reduced, and the air is dispersed more evenly when flowing. An annular air guide frame 8 coaxially arranged with the boss 10 is also installed on the top of the supporting shell 1. The air guide frame 8 is connected to the air flow channel 11. A plurality of annular activated carbon filters 81 for absorbing pollutants and odors in the air are arranged in the air guide frame 8. The air first passes through the activated carbon filter 81 in the air guide frame 8 to filter out pollutants and odors in the air. After the filtering is completed, the air is guided by the air flow channel 11 and finally blown out from the air outlet 14.

[0031] Furthermore, a driving motor 13 with an output shaft facing upward and coaxially arranged with the boss 10 is installed in the boss 10, a wind wheel 12 is provided in the air flow channel 11, and the wind wheel 12 is installed on the output shaft of the driving motor 13; a first hose 501 and a second hose 601 are also provided inside the supporting shell 1, one end of the first hose 501 is connected to the interior of the air guide frame 8, and the other end is connected to the upper filter part 5, and one end of the second hose 601 is connected to the interior of the air guide frame 8, and the other end is connected to the lower filter part 6. The driving motor 13 is operated to drive the wind wheel 12 to rotate. The wind wheel 12 generates airflow through rotation, so that the upper filter part 5 and the lower filter part 6 generate suction at the same time, and the indoor air is sucked in and filtered through the upper filter part 5 and the lower filter part 6 to filter out the particles and impurities in the air. Then, the filtered air enters the air guide frame 8 under the conveying action of the first hose 501 and the second hose 601, and the pollutants and odors in the air are filtered out through the activated carbon filter 81. Finally, the air is guided through the airflow channel 11 (such as Figure 3In addition, in the process of circulating and filtering the air, the upper movable frame 3 and the lower movable frame 4 are controlled 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 range of absorption.

[0032] In addition, a control component 7 is installed on the support column 2 for controlling 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, the base 17 is provided with a plurality of vertically arranged guide columns 18, and the bottom of the support shell 1 is slidably arranged up and down on the guide columns 18, and a first spring 19 is wound around the guide columns 18, and the first spring 19 is placed between the support shell 1 and the base 17 to apply an upward thrust to the support shell 1; a pressure-applying component 20 is installed inside the support shell 1 for intermittently applying downward pressure to the support shell 1 so that it moves intermittently downward, and a linkage component 21 is also installed to drive the control component 7 to operate when the support shell 1 moves up and down. By operating the pressure-applying component 20, downward pressure can be applied to the supporting shell 1 to make it move downward, and the first spring 19 is compressed. Then the pressure-applying component 20 stops applying pressure to the supporting shell 1, and under the action of the compressed first spring 19, the supporting shell 1 is pushed to move upward, thereby controlling the supporting shell 1 to move up and down. During the movement, the control component 7 is driven by the linkage component 21 to operate so as to control the upper movable frame 3 and the lower movable frame 4 to rotate back and forth in opposite directions. While driving 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 supporting column 2, the pair of upper filter parts 5 and a pair of lower filter parts 6 are also driven to move up and down, further improving the range of air absorption and the filtering efficiency.

[0033] A protective shell 15 for covering the cover body 9 is also provided on the top of the supporting shell 1. An opening is provided on the top of the protective shell 15 coaxially with the air outlet 14, and a wind guide blade 16 is installed at the opening. After the filtered air is discharged from the air outlet 14, the wind direction is controlled by the wind guide blade 16, so that the air is blown out from a specified direction, thereby improving the user experience. In addition, the protective shell 15 can be rotatably set on the top of the supporting shell 1, so as to change the direction of the wind guide blade 16 according to the user's needs to control the direction of the air blowing out.

[0034] The upper filter part 5 and the lower filter part 6 have the same structure and the same installation method. Figure 4As shown, the upper filter portion 5 includes a support portion 51 arranged on the upper movable frame 31, a mounting chamber 52 is formed in the support portion 51, and a HEPA filter 53 for secondary filtering of the air is installed in the mounting chamber 52, wherein the HEPA filter 53 is a prior art, and 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 portion 51 is also provided with a filter cover 56 for covering the installation chamber 52 and performing a first filtration on the air. The HEPA filter 53 is first installed inside the installation chamber 52, and then the filter cover 56 is installed on the support portion 51, so as to cover the installation chamber 52. During the inhalation 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 air first passes through the filter cover 56 for the first filtration, which is mainly used to capture larger particles such as dust, hair, and fiber to prevent them from entering the HEPA filter 53, thereby 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 plurality of embedding grooves 54 are formed on the outer wall of the frame of the HEPA filter 53, and a plurality of embedding blocks 55 which can be respectively embedded in different embedding grooves 54 are formed on the inner wall of the installation chamber 52; during the process of installing the HEPA filter 53 in the installation chamber 52, the plurality of embedding blocks 55 are respectively embedded in different embedding grooves 54 to achieve stable installation of the HEPA filter 53; and, through the embedded installation method, the HEPA filter 53 can be easily disassembled for maintenance and repair. In order to facilitate the installation of the filter cover body 56, a plurality of positioning convex edges 57 are provided on the top and bottom of the filter cover body 56, and a plurality of positioning grooves 58 are formed on the top and bottom of the support part 51 for the positioning convex edges 57 to be embedded. The positioning convex edges 57 are magnetic metal parts, and a magnet 59 for attracting the positioning convex edges 57 is installed in each positioning groove 58; when installing the filter cover body 56, the plurality of positioning convex edges 57 are respectively embedded in different positioning grooves 58. At this time, the magnet 59 attracts the positioning convex edges 57, and the installation of the filter cover body 56 is completed. The installation method through magnetic attraction is also for the convenience of disassembly and installation. After sufficient external force is applied to the filter cover body 56, the positioning convex edges 57 automatically separate from the magnet 59, so that the filter cover body 56 can be cleaned easily.

[0036] The upper filter portion 5 also includes a connecting tube 510, which is placed on the side of the HEPA filter 53 away from the filter cover 56, and one end of the connecting tube 510 is connected to the installation chamber 52, and the other end is connected to the first hose 501, thereby realizing the connection between the first hose 501 and the installation chamber 52, so that the air is guided through the first hose 501 after the first and second filtrations.

[0037] like Figure 5 As shown, the control component 7 includes a fixed housing 71 arranged on the support column 2, and an upper sleeve 72 and a lower sleeve 74 are rotatably provided on the outer side of the support column 2, the bottom end of the upper sleeve 72 extends into the fixed housing 71, and a first bevel gear 73 is installed on the bottom end of the upper sleeve 72, and the top end of the lower sleeve 74 extends into the fixed housing 71, and a second bevel gear 75 is installed on the top end of the upper sleeve 72; a rotating shaft 76 with a transversely arranged axis is rotatably provided 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 installed on the end, and the third bevel gear 77 is meshed with the first bevel gear 73 and the second bevel gear 75 at the same time. When the driving shaft 76 rotates, the third bevel gear 77 is driven to rotate, and at this time, the first bevel gear 73 and the second bevel gear 75 are driven to rotate at the same time, and the directions of rotation of the two are opposite, so that the upper sleeve 72 and the lower sleeve 74 rotate in opposite directions on the support column 2. In addition, the upper movable frame 3 is mounted on the upper shaft sleeve 72, and the lower movable frame 4 is mounted on the lower shaft sleeve 74. When the upper shaft sleeve 72 and the lower shaft sleeve 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 realize that the upper movable frame 3 and the lower movable frame 4 can rotate back and forth when rotating in opposite directions, the driving shaft 76 can be driven forward and reverse.

[0038] Furthermore, the linkage component 21 includes a guide block 211 installed at the bottom of the supporting shell 1, and a lifting rod 212 that can slide up and down is provided on the guide block 211. The top end of the lifting rod 212 extends into the supporting shell 1, and the bottom end of the lifting rod 212 extends to the outside of the supporting shell 1. A limit 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 limit block 213 to apply a downward thrust to the limit block 213. The operating pressure component 20 applies a downward thrust to the support shell 1 to control the support shell 1 to move downward on the base 17. During the movement, a thrust is applied to the limit block 213 to push the lifting rod 212 to move 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 shell 1, the first spring 19 is compressed to push the support shell 1 to move upward on the base 17, and the upward thrust on the limit block 213 can be stopped. Under the action of the compressed second spring 214, a downward thrust is applied to the limit block 213 to make the lifting rod 212 move upward on the guide block 211. In addition, a vertically arranged rack 215 is provided on the lifting rod 212, and a driving gear 216 meshing with the rack 215 is installed on the rotating shaft 76; when the pressure-applying component 20 controls the supporting shell 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, so as to drive the gear 216 to rotate forward and reverse, and make the rotating shaft 76 rotate forward and reverse, thereby achieving a linkage effect.

[0039] like Figure 6As shown, the pressure-applying component 20 includes a rotating rod 201 disposed at the bottom of the supporting shell 1 and arranged with its axis transversely. A plurality of cams 202 are mounted on the rotating rod 201. When the rotating rod 201 is driven to rotate, the swinging ends of the plurality of cams 202 can be driven to swing around the axis of the rotating rod 201. It also includes fixing members 203, which are the same in number as the cams 202 and are disposed on the top surface of the base 17. The fixing members 203 are in an "n" shape, and the tops extend to the inside of the supporting shell 1. The plurality of cams 202 are respectively disposed on the inner sides of different fixing members 203. The inner side walls of the fixing members 203 are formed with limiting grooves 204 for limiting the swinging ends of the cams 202. When the swinging ends of the cams 202 are at the same level as the rotating rod 201, or when the swinging ends are lower than the rotating rod 201, the supporting shell 1 is at the highest point. When the rotating rod 201 is driven, the swinging ends of the cams 202 are at the same level as the rotating rod 201, or when the swinging ends of the cams 202 are lower than the rotating rod 201, the supporting shell 1 is at the highest point. After 201 rotates, the swinging ends of the cams 202 are driven to swing around the axis of the rotating rod 201. After swinging to contact with the top wall in the limiting groove 204, because the fixing member 203 is fixed, the swinging can continue to exert downward pressure on the supporting shell 1, so that the supporting shell 1 moves downward. When the swinging end of the cam 202 swings to below the rotating rod 201, under the action of the compressed first spring 19, the supporting shell 1 is pushed to move upward on the base 17, and the supporting shell 1 is controlled to move up and down differently by driving the cam 202 to swing continuously. In addition, under the action of the limiting groove 204, the cam 202 can accurately contact with the internal top wall of the fixing member 203 when it swings continuously to prevent deviation. A servo motor 205 is installed at the inner bottom of the supporting shell 1, and the output shaft of the servo motor 205 is connected to the end of the rotating rod 201. When the servo motor 205 is operated, the rotating rod 201 can be driven to rotate.

[0040] In summary, it can be seen that the present invention has the above-mentioned excellent characteristics, which can enhance the performance unprecedented in the prior art and become a product with great practical value.
