Description
Technical Field
[0001] This invention relates to the technical field of air purification, and in particular to an energy-saving air purification device. Background Technology
[0002] The main function of air purifiers is to remove particulate matter, harmful gases, and odors from the air to provide a clean and healthy air environment. In existing air purifiers, the filter cartridge is a key component, capturing dust and pollutants from the air through physical filtration. However, over time, a large amount of dust accumulates on the filter cartridge, leading to a decrease in filtration efficiency and reduced air purification effectiveness. Therefore, regularly cleaning the filter cartridge is an important measure to maintain the performance of air purifiers.
[0003] Currently, there are two main methods for cleaning filter cartridges: manual cleaning and automatic cleaning. Manual cleaning requires removing the filter cartridge and cleaning it with tools such as a brush or vacuum cleaner. This method is not only time-consuming and labor-intensive, but also easily damages the filter cartridge. Automatic cleaning uses internal cleaning devices, such as brushes, vacuum cleaners, or water washing systems, to automatically clean the filter cartridge. While this method is convenient and quick, the cleaning effect is often less than ideal, and it requires additional cleaning equipment and energy consumption.
[0004] Therefore, existing air purification equipment has some problems with cleaning the filter cartridges, and a more convenient, efficient and reliable cleaning method is needed to improve the performance and service life of air purification equipment. Summary of the Invention
[0005] The purpose of this invention is to provide an energy-saving air purification device that solves the problem of inconvenience in cleaning the filter cartridge of existing air purification devices.
[0006] The present invention is implemented as follows: an energy-saving air purification device includes a lower base and an upper base arranged in a circle. The lower base and the upper base are connected by a bracket. The inner walls of the lower base and the upper base are respectively connected by bearings to an upper rotating ring and a lower rotating ring. A filter cartridge is snapped between the upper rotating ring and the lower rotating ring. A purification component is also provided on the top of the upper base.
[0007] A support rod is also provided between the middle of the lower base and the upper base. Two fan-shaped partitions are installed on the outside of the support rod. The two partitions are hollow to form an air inlet chamber and an air outlet chamber. When the filter cartridge corresponding to the air inlet chamber is blocked, negative pressure is generated in the air inlet chamber to drive the filter cartridge to rotate.
[0008] Preferably, an exhaust fan is installed at both the inlet and outlet of the purification component, and the inlet and outlet of the purification component are respectively connected to an exhaust pipe extending into the air inlet chamber and an air inlet pipe extending into the air outlet chamber via the exhaust fan.
[0009] Preferably, the arc-shaped surfaces of the two partitions abut against the inner wall of the filter cartridge, and the air inlet and outlet chambers of the partitions are provided with air vents on the side near the inner wall of the filter cartridge.
[0010] Preferably, a dust baffle is installed on the upper base near the corresponding part of the air outlet chamber via a damping pivot. The inner wall of the dust baffle is lined with lint, and a push-pull bracket is slidably installed on the outer side of the dust baffle.
[0011] A dust collection box is inserted into the bottom of the dust baffle, and one side of the dust collection box abuts against the bottom surface of the filter cartridge. The inner and outer walls of the push-pull bracket near the filter cartridge are equipped with scrapers.
[0012] Preferably, the inner wall of the air inlet chamber away from the air outlet chamber is connected to a shut-off valve via a spring shaft, and a plurality of negative pressure holes are provided on one side of the air inlet chamber, the negative pressure holes being sealed by the shut-off valve.
[0013] Preferably, the end of the air-closing valve is provided with a drive plate, and the inside of the drive plate is connected by a spring to a push tongue extending to the outside of the drive plate;
[0014] The partition is provided with a groove on the arc-shaped side of the air intake chamber. The end of the push tongue extends through and to the outside of the groove. A baffle is fitted over the push tongue at the corresponding position of the groove. The baffle is used to seal the groove.
[0015] Preferably, the inner wall of the upper rotating ring is evenly provided with transmission teeth corresponding to the push tongue, the cross-section of the transmission teeth is set at a right angle, and the hypotenuse of the transmission teeth faces the direction of the air outlet chamber;
[0016] The end of the pusher tongue is provided with a reverse bevel, which is arranged facing the bevel of the transmission tooth.
[0017] Preferably, the purification component has a purification cylinder inside, which includes an inner cylinder and an ozone generator. The inner cylinder is filled with a fiberglass layer, a ceramic filter layer and a HEPA filter layer from top to bottom. One side of the inner cylinder is connected to the air inlet pipe of the ozone generator. The air inlet of the inner cylinder and the air outlet of the ozone generator are respectively connected to the air outlet and air inlet of the two exhaust fans.
[0018] The beneficial effects of the energy-saving air purification device disclosed in this invention are:
[0019] 1. The core component of this equipment is a rotatable cylindrical filter cartridge. The inside of the filter cartridge is divided into an air inlet chamber and an air outlet chamber by two fan-shaped baffles, which divide the filter cartridge into two independent areas for air intake and exhaust. The arc-shaped surface of the baffles fits tightly against the inner wall of the filter cartridge, ensuring effective isolation between the two areas. When the part of the filter cartridge corresponding to the air inlet chamber becomes blocked, a negative pressure is generated in the air inlet chamber. This negative pressure drives the filter cartridge to rotate, turning the blocked part towards the air outlet chamber. It utilizes the natural force generated by air flow to achieve automatic rotation of the filter cartridge without additional power.
[0020] 2. The filter cartridge corresponding to the air outlet chamber of this equipment will be subjected to reverse airflow when air is discharged, which will blow off the attached dust. This reverse airflow cleaning method can effectively extend the service life of the filter cartridge, reduce the replacement frequency, and thus reduce maintenance costs. A dust baffle is installed on the outside of the upper base, and its inner wall is lined with sticky fibers, which can effectively capture the dust blown down. The dust collection box at the bottom of the dust baffle further collects dust, which is convenient for regular cleaning. The scraper on the push-pull frame can clean the surface of the filter cartridge and the inner wall of the dust baffle, making maintenance work more convenient.
[0021] 3. This equipment features a purification system, including an inner cylinder and an ozone generator. The inner cylinder is filled from top to bottom with a fiberglass layer, a ceramic filter layer, and a HEPA filter layer. This multi-layered filtration structure effectively removes various pollutants from the air. The air after multi-layer filtration is then treated by the ozone generator. Ozone has a strong oxidizing ability, which can further sterilize and disinfect, improving air quality. The treated air is then sent to the outlet chamber for backflushing and cleaning the filter cartridges. Attached Figure Description

[0041] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.
[0042] In the accompanying drawings of this embodiment, the same or similar reference numerals correspond to the same or similar components. In the description of this invention, it should be understood that if terms such as "upper," "lower," "left," and "right" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, they are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting this invention. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.
[0043] The implementation of the present invention will be described in detail below with reference to specific embodiments.
[0044] In this embodiment:
[0045] Reference Figure 1 The diagram shows a preferred embodiment of the present invention.
[0046] The energy-saving air purification device of this embodiment includes a circular lower base 1 and an upper base 12. The lower base 1 and the upper base 12 are connected by a bracket 11. The inner walls of the lower base 1 and the upper base 12 are respectively connected by bearings to an upper rotating ring 121 and a lower rotating ring 122. A filter cartridge 3 is snapped between the upper rotating ring 121 and the lower rotating ring 122, which allows the filter cartridge 3 to rotate through the upper rotating ring 121 and the lower rotating ring 122. A purification component 4 is also provided on the top of the upper base 12.
[0047] A support rod 5 is also provided between the lower base 1 and the upper base 12. Two fan-shaped partitions 51 are installed on the outside of the support rod 5. The two partitions 51 are hollow to form an air inlet chamber 511 and an air outlet chamber 512. When the filter cartridge 3 corresponding to the air inlet chamber 511 is blocked, a negative pressure is generated in the air inlet chamber 511 to drive the filter cartridge 3 to rotate. This is used to rotate the blocked part of the filter cartridge 3 from the corresponding position in the air inlet chamber 511 to the corresponding position in the air outlet chamber 512. This allows the dust blocking the surface of the filter cartridge 3 at the corresponding position in the air inlet chamber 511 to be blown away by the reverse airflow at the corresponding position in the air outlet chamber 512, so that the filter cartridge 3 of the purification device can achieve the self-cleaning function.
[0048] In the appendix Figure 2 In this design, a dust baffle 2 is mounted on the upper base 12 near the air outlet chamber 512 via a damping shaft. The inner wall of the dust baffle 2 is lined with adhesive fibers. The air discharged from the air outlet chamber 512 blows the dust adhering to the surface of the filter cartridge 3 back onto the adhesive fibers of the dust baffle 2. The adhesive fibers can effectively stick to the dust and hair. A push-pull bracket 22 is also slidably mounted on the outside of the dust baffle 2. A dust collection box 21 is inserted into the bottom of the dust baffle 2. One side of the dust collection box 21 abuts against the bottom surface of the filter cartridge 3. The inner and outer walls of the push-pull bracket 22 near the filter cartridge 3 are provided with scraper brushes 221. By moving the push-pull bracket 22 up and down, the scraper brushes 221 can be used to scrape and brush the surface of the filter cartridge 3 and the inner wall of the dust baffle 2, so that the attached dust and hair can be brushed into the dust collection box 21 for collection and easy cleaning.
[0049] Further, refer to the appendix. Figure 3 As shown, each of the inlet and outlet of the purification component 4 is equipped with an exhaust fan 44. The inlet and outlet of the purification component 4 are respectively connected to an exhaust pipe 441 extending into the air inlet chamber 511 and an air inlet pipe 442 extending into the air outlet chamber 512 via the exhaust fan 44. The two exhaust fans 44 draw air from the filter cartridge 3 corresponding to the air inlet chamber 511 into the purification component 4 and discharge the purified air from the filter cartridge 3 corresponding to the air outlet chamber 512.
[0050] In the appendix Figure 4 In the middle, the arc-shaped surfaces of the two partitions 51 abut against the inner wall of the filter cylinder 3, and the air inlet chamber 511 and the air outlet chamber 512 of the partition 51 are provided with air vents on the side near the inner wall of the filter cylinder 3. Air can only enter and exit through the filter cylinder 3 at the corresponding air vents of the air inlet chamber 511 and the air outlet chamber 512, so that the filter cylinder 3 at the corresponding air vents can filter the air and perform backflushing operation.
[0051] It is worth noting that, referring to the appendix Figure 5 As shown, the inner wall of the air intake chamber 511 away from the air outlet chamber 512 is connected to a shut-off valve 52 via a spring shaft, and a number of negative pressure holes 513 are opened on one side of the air intake chamber 511. The negative pressure holes 513 are sealed by the shut-off valve 52, so that the air intake chamber 511 forms a sealed space, which facilitates the intake of air through the filter cartridge 3 corresponding to the air intake chamber 511. When the filter cartridge 3 corresponding to the air intake chamber 511 is blocked, the shut-off valve 52 is opened due to the negative pressure in the air intake chamber 511. During the opening process, the drive plate 53 at the top of the shut-off valve 52 will rotate and open together.
[0052] The air-closing valve 52 is provided with a drive plate 53 at its end. The drive plate 53 is connected to a push tongue 531 extending to the outside of the drive plate 53 by a spring. The partition 51 is provided with a groove 514 on the arc-shaped side of the air intake chamber 511. The end of the push tongue 531 passes through and extends to the outside of the groove 514. A baffle 532 is sleeved on the push tongue 531 at the corresponding position of the groove 514. The baffle 532 is used to seal the groove 514. This makes the push tongue 531 pushed out of the groove 514 by the spring in the default state.
[0053] It is worth noting that the inner wall of the upper rotating ring 121 is evenly distributed with transmission teeth 1211 corresponding to the push tongue 531. The cross-section of the transmission teeth 1211 is set at a right angle, and the hypotenuse of the transmission teeth 1211 faces the direction of the air outlet chamber 512. The end of the push tongue 531 is provided with a reverse inclined surface, which is set opposite to the hypotenuse of the transmission teeth 1211. This allows the push tongue 531 to push the upper rotating ring 121 to rotate in the forward direction through the right angle side of the transmission teeth 1211 during the sliding process in the slide groove 514. When the push tongue 531 returns to its original position, the push tongue 531... The presence of the reverse inclined surface and the inclined edge of the transmission gear 1211 causes the pusher tongue 531 to compress the spring in the drive plate 53 and reset. During the reset process, the upper rotating ring 121 will not rotate in the opposite direction. Thus, the pusher tongue 531 can continuously rotate the upper rotating ring 121 in the forward direction by sliding back and forth. This allows the unblocked filter cartridge 3 to rotate into the air inlet chamber 511, while the blocked filter cartridge 3 rotates into the air outlet chamber 512, completing the continuous rotation. This ensures that the air entering the filter cartridge 3 is not blocked by dust, while the blocked part of the filter cartridge 3 can be continuously back-blown, completing the automatic switching and cleaning functions.
[0054] Further, refer to the appendix. Figure 6 As shown, the purification component 4 has a purification cylinder 41 inside, which includes an inner cylinder 42 and an ozone generator 43. The inner cylinder 42 is filled from top to bottom with a fiberglass layer 421, a ceramic filter layer 422, and a HEPA filter layer 423. One side of the inner cylinder 42 is connected to the air inlet pipe of the ozone generator 43. The air inlet of the inner cylinder 42 and the air outlet of the ozone generator 43 are respectively connected to the air outlet and air inlet of the two exhaust fans 44. Air entering the purification component 4 through the air inlet pipe 442 is filtered sequentially through the fiberglass layer 421, the ceramic filter layer 422, and the HEPA filter layer 423. The fiberglass layer 421 has… With a fine fiber structure, it can effectively capture fine particulate matter and moisture in the air. The HEPA filter layer 423 is characterized by a removal efficiency of more than 99.97% for particles with a diameter of 0.3 micrometers (μm). It is made of very fine fiber material, forming an intricate mesh structure that allows air to pass through, but small particles are intercepted on the filter material. The ceramic filter layer 422 works in conjunction with the HEPA filter layer 423 to achieve comprehensive purification of air and harmful gases. After the purified air is used to generate ozone by the ozone generator 43, it is sent from the air outlet pipe 441 into the air outlet chamber 512 to perform a backflushing operation on the clogged filter cartridge 3.
[0055] This device adopts a circular structure, consisting of an upper base 12 and a lower base 1 connected by a bracket 11. The core component is a rotatable cylindrical filter cartridge 3. The interior of the filter cartridge 3 is divided into an air inlet chamber 511 and an air outlet chamber 512 by two fan-shaped partitions 51, dividing the filter cartridge 3 into two independent areas for air intake and exhaust. The arc-shaped surface of the partition 51 fits tightly against the inner wall of the filter cartridge 3, ensuring effective isolation between the two areas. When the part of the filter cartridge 3 corresponding to the air inlet chamber 511 becomes blocked, a negative pressure is generated in the air inlet chamber 511. This negative pressure drives the filter cartridge 3 to rotate, turning the blocked part towards the air outlet chamber 512. It utilizes the natural force generated by airflow to achieve automatic rotation of the filter cartridge without additional power.
[0056] The filter cartridge 3 corresponding to the air outlet chamber 512 of this equipment will be subjected to reverse airflow, which will blow off the attached dust. This reverse airflow cleaning method can effectively extend the service life of the filter cartridge 3, reduce the replacement frequency, and thus reduce maintenance costs. A dust baffle 2 is installed on the outside of the upper base 12, and its inner wall is lined with sticky hair, which can effectively capture the dust blown down. The dust collection box 21 at the bottom of the dust baffle 2 further collects dust, which is convenient for regular cleaning. The scraper 221 on the push-pull frame 22 can clean the surface of the filter cartridge 3 and the inner wall of the dust baffle 2, making maintenance work more convenient.
[0057] This device has a purification component 4, comprising an inner cylinder 42 and an ozone generator 43. The inner cylinder 42 is filled from top to bottom with a fiberglass layer 421, a ceramic filter layer 422, and a HEPA filter layer 423. This multi-layer filtration structure effectively removes various pollutants from the air. The air after multi-layer filtration is then treated by the ozone generator 43. Ozone has a strong oxidizing ability, which can further sterilize and disinfect, improving air quality. The treated air is then sent to the outlet chamber 512 for backflushing and cleaning the filter cartridge 3.
[0058] The entire device is designed with energy conservation and environmental protection in mind. Automatic rotation and self-cleaning functions reduce manual intervention and the frequency of filter media replacement. The natural force generated by airflow drives the rotation of filter cartridge 3, avoiding additional power consumption. Multi-layer filtration and ozone treatment ensure highly efficient purification, while the backflushing system extends the lifespan of filter cartridge 3 and reduces waste generation.
[0059] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
