Description

Technical Field

[0001] This invention relates to the field of air purifier technology, and more particularly to an air purifier that efficiently removes volatile organic compounds. 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 decoration pollution such as formaldehyde), effectively improving air cleanliness. They are mainly household and commercial air purifiers used to remove indoor air pollution.

[0003] Air purifiers typically employ a combination of passive and active purification methods. A motor circulates indoor air, and polluted air passes through an internal air filter to remove or adsorb various pollutants. The air then passes through a negative ion generator, ionizing the air and producing negative ions, which are then dispersed by a gentle breeze to create a negative ion airflow, thus achieving the purpose of cleaning and purifying the air. The main components include the outer casing, filter section, air duct design, motor, power supply, and LCD display. Key technologies include activated carbon adsorption, ion filtration, ozone sterilization, and high-efficiency air filters.

[0004] Existing air purifiers have significant drawbacks in practical applications: On the one hand, while the filter absorbs dust and particulate matter, it can become a breeding ground for bacteria, viruses, and other microorganisms; if the filter is not replaced for a long time, microorganisms will multiply in large numbers and be blown back into the room with the airflow, causing secondary pollution; on the other hand, the air purifier filter needs to be replaced regularly, usually every six months. Original filter cartridges are expensive, possibly reaching 1 / 3 of the selling price. Even if universal filter cartridges are used, it will cost several hundred yuan per year, which is a considerable expense in the long run.

[0005] Therefore, an air purifier that can efficiently remove volatile organic compounds is needed. Summary of the Invention

[0006] This invention proposes an efficient air purifier for removing volatile organic compounds, solving the problems of existing technologies where filters, while adsorbing dust and particulate matter, can become a breeding ground for bacteria, viruses, and other microorganisms; if the filter is not replaced for a long time, microorganisms will multiply rapidly and be blown back into the room by the airflow, causing secondary pollution; on the other hand, air purifier filters need to be replaced regularly, usually every six months.

[0018] This invention proposes an air purifier that efficiently removes volatile organic compounds. Compared with existing technologies, the advantages of this invention are:

[0019] 1. This invention, by setting up a dust removal mechanism, can effectively remove dust from the filter element, thus significantly improving its practical value. Since the driving gear and the arc-shaped rack form a meshing connection structure, when the driving gear delivers power, it will drive the rotating ring to rotate. The limiting protrusion at the top of the rotating ring will slide and embed into the arc-shaped groove inside the limiting ring, thereby driving the limiting ring to rotate. The brush on the limiting ring can sweep away the dust and particles adsorbed on the filter element, causing them to fall into the dust collection arc groove, thus enabling it to have a self-cleaning function and improving its self-cleaning ability. The connecting slide rod connects to the inner wall of the purification cylinder, providing support for the dust removal mechanism. The surface of the limiting ring has a T-shaped slide groove that slides and embeds with the connecting slide rod, providing a limiting effect for the limiting ring and ensuring its positional accuracy while rotating.

[0020] 2. This invention, by setting up a counterforce mechanism and a dust collection tray, enables dust collection and convenient installation and disassembly of the purifier. When the dust collection tray needs to be disassembled, the telescopic spring is engaged, causing the roller to slide, which presses down the main counterforce rod and the secondary counterforce rod, causing the counterforce plate to descend and removing its supporting function for the dust collection tray. The dust collection tray is equipped with a detachable partition groove, and the partition plate has a rotating structure, which can realize the function of cleaning and collecting dust and particulate matter adsorbed on the filter element in separate compartments, preventing excessive accumulation of dust and particulate matter, thereby preventing pollution of the purifier's interior through the dust removal cylinder.

[0021] 3. This invention, by setting up a lifting mechanism, can lift the filter element, facilitating the dust removal mechanism to perform all-round cleaning of the filter element; when operation is required, the control limit disc rotates, which drives the active rod to rotate inward, thereby driving the sector disc to move. Since the end of the sector disc away from the active rod is provided with a rotating shaft for limiting the rotation of the sector disc, the sector disc will rotate inward, driving the sector abutment column to form an enclosing structure, thereby providing a lifting effect on the abutment cone, indirectly increasing the height of the filter element, and realizing the dust removal operation of the dust removal mechanism on the surface of the filter element;

[0022] 4. By setting up a dust collection arc groove and a dust collection cylinder, the present invention can effectively collect and discharge the dust and particulate matter swept down by the dust removal mechanism; the particulate matter swept down by the dust removal mechanism can slide from the dust collection arc groove to the dust collection cylinder, and the dust collection cylinder corresponds to a single partition groove to effectively collect the particulate matter; the design of the dustproof cylinder can enhance the air circulation while preventing particulate matter on the dust collection arc groove from entering it.

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0036] Please see Figure 1-10 The present invention provides a technical solution: an air purifier that efficiently removes volatile organic compounds, including a support base 1, a detachable anti-force mechanism 2 on the top of the support base 1, and a detachable dust collection tray 3 on the top of the anti-force mechanism 2.

[0037] The top of the dust collection tray 3 is equipped with a purification cylinder 4, the side of the purification cylinder 4 is equipped with an air outlet duct 5, the inner wall of the top of the purification cylinder 4 is equipped with a detachable dust removal mechanism 12, the interior of the dust removal mechanism 12 is equipped with a filter element 13, and the side of the dust removal mechanism 12 is meshed with a drive gear 18 for providing power.

[0038] Furthermore, the resisting mechanism 2 is equipped with a tension spring 201. The end of the tension spring 201 is equipped with a roller 202 for sliding limit. The end of the roller 202 is equipped with a limit slot 203 for controlling the rotation of the main resisting rod 204. The top of the main resisting rod 204 is rotatably connected to a liftable resisting plate 206. The bottom of the resisting plate 206 is equipped with a rotatable resisting auxiliary rod 205. The resisting plate 206 and the dust collection tray 3 form a supporting structure. This provides convenient installation and disassembly for collecting dust from the purifier. When the dust collection tray 3 needs to be disassembled, the tension spring 201 is engaged, which drives the roller 202 to slide, causing the main resisting rod 204 and the resisting auxiliary rod 205 to press down, causing the resisting plate 206 to descend and remove its supporting function on the dust collection tray, thereby realizing convenient disassembly of the dust collection tray 3.

[0039] Furthermore, the surface of the dust collection tray 3 is provided with detachable and installable partition grooves 301 at equal intervals in a circular shape. One end of the partition groove 301 is provided with a rotatable partition plate 302. The partition groove 301 has a rotating structure about the partition plate 302. The dust collection tray 3 is provided with detachable and installable partition grooves 301 and the partition plate 302 has a rotating structure. This can realize the function of separate cleaning and collection of dust and particulate matter adsorbed on the filter element 13, and prevent excessive accumulation of dust and particulate matter, thereby causing pollution to the inside of the purifier through the dust collection cylinder 16.

[0040] Furthermore, the dust removal mechanism 12 has a rotatable rotating ring 1201 inside, and an arc-shaped rack 1202 that meshes with the drive gear 18 inside the rotating ring 1201. Limiting protrusions 1203 are evenly distributed on the top of the rotating ring 1201. A limiting ring 1204 that is slidably connected to the limiting protrusions 1203 is sleeved on the rotating ring 1201. A detachable connecting slide rod 1205 is provided on the surface of the limiting ring 1204. A detachable brush 1206 is evenly distributed on the surface of the limiting ring 1204. Since the drive gear 18 and the arc-shaped rack 1202 form a meshing connection structure, when the drive gear 18 transmits power, it will drive the rotating ring 1201 to rotate. The limiting protrusion 1203 at the top of the rotating ring 1201 will slide into the arc-shaped groove opened inside the limiting ring 1204, thereby driving the limiting ring 1204 to rotate. The brush 1206 on the limiting ring 1204 can clean the dust and particles adsorbed on the filter element 13, so that they fall into the dust collection arc groove 14, giving it a self-cleaning function and improving its self-cleaning ability.

[0041] Furthermore, the limiting ring 1204 is equidistantly sleeved on the surface of the rotating ring 1201. The inner wall of the limiting ring 1204 is provided with an arc-shaped groove that is slidably embedded in the limiting protrusion 1203. The surface of the limiting ring is provided with a T-shaped groove that is slidably embedded in the connecting slide rod 1205. The end of the connecting slide rod 1205 is connected to the inner wall of the purification cylinder 4. The connection between the connecting slide rod 1205 and the inner wall of the purification cylinder 4 can provide support for the dust removal mechanism 12. The surface of the limiting ring 1204 is provided with a T-shaped groove that is slidably embedded in the connecting slide rod 1205, which can provide a limiting effect for the limiting ring 1204, ensuring the accuracy of its position while it rotates.

[0042] Furthermore, the top of the filter element 13 is provided with a detachable connecting disc 1301, and the bottom is provided with a detachable filter screen 1302. The bottom of the filter screen 1302 is provided with a lifting engagement post 1303 that engages with another set of connecting discs 1301. The bottom of the lifting engagement post 1303 is provided with a resisting cone 1304, and the lifting engagement post 1303 is provided with a buckle that engages with a slot on the connecting disc 1301. The lifting engagement post 1303 and the limiting cylinder 17 are in a tight fit structure. The buckle of the lifting engagement post 1303 and the slot on the connecting disc 1301 are connected by a buckle. The groove facilitates the disassembly and replacement of the filter 1302. The filter 1302 has a multi-layer design, consisting of a pre-filter, a HEPA filter, an activated carbon layer, and an additional layer. The pre-filter can filter large particles such as dust and hair, the HEPA filter can efficiently filter PM2.5, bacteria, and other particles, the activated carbon layer can adsorb harmful gases such as formaldehyde and odors, and the additional layer is an antibacterial layer. At the same time, the lifting locking column 1303 and the limiting cylinder 17 fit together to effectively prevent particles from entering when the dust removal mechanism 12 cleans the filter element 13, thereby preventing pollution inside the purifier.

[0043] Furthermore, the bottom of the lifting mechanism 19 is provided with a rotatable limiting disc 1901. Inside the limiting disc 1901 is a rotatable driving rod 1902. One end of the driving rod 1902 is provided with a rotatable sector disc 1903. The end of the sector disc 1903 away from the driving rod 1902 is provided with a rotating shaft for limiting the rotation of the sector disc 1903. The port of the sector disc 1903 is provided with a sector-shaped abutment 1904 with an inclined structure. A limiting rod 1905 for limiting sliding is sleeved on the side of the limiting disc 1901. One end of the limiting rod 1905 is connected to the inside of the purification cylinder 4. A resisting cone 1304 is opened in the center of the limiting disc 1901. The limiting hole can lift the filter element 13, facilitating the dust removal mechanism 12 to perform all-round cleaning of the filter element 13. When operation is required, the limiting disc 1901 is rotated, which will drive the active rod 1902 to rotate inward, thereby driving the sector disc 1903 to move. Since the end of the sector disc 1903 away from the active rod 1902 is provided with a rotating shaft for limiting the rotation of the sector disc 1903, the sector disc 1903 will rotate inward, driving the sector abutment 1904 to form an enclosing structure, thereby providing a lifting effect on the abutment cone 1304, indirectly raising the height of the filter element 13, and realizing the dust removal operation of the dust removal mechanism 12 on the surface of the filter element 13.

[0044] Furthermore, the inner wall of the purification cylinder 4 is provided with two sets of dust collection arc grooves 14 in an inclined symmetrical structure. A dustproof cylinder 15 is provided at the top of the junction of the two sets of dust collection arc grooves 14, and a dust removal cylinder 16 for dust discharge is provided at the bottom of the junction of the two sets of dust collection arc grooves 14. A limiting cylinder 17 for limiting and preventing dust from the filter element 13 is provided at the top of the dust collection arc grooves 14. This can effectively collect and discharge the dust and particulate matter swept down by the dust removal mechanism 12. The particulate matter swept down by the dust removal mechanism 12 can slide from the dust collection arc grooves 14 to the dust removal cylinder 15. 6. The dust collection cylinder 16 corresponds to the individual partition groove 301, which can effectively collect particulate matter. The design of the dustproof cylinder 15 can enhance the air circulation while preventing particulate matter on the dust collection arc groove 14 from entering it. At the same time, if a lot of particulate matter is adsorbed on the surface of the dust collection arc groove 14, disinfectant can be poured into the inner wall of the purification cylinder 4. The disinfectant will flow from the dust collection arc groove 14 into the dust collection cylinder 16 and finally be collected by the partition groove 301, which can effectively clean the particulate matter adsorbed on the surface of the dust collection arc groove 14.

[0045] Furthermore, the top of the purification cylinder 4 is provided with a detachable top cover 6, the middle of the top cover 6 is provided with an air intake fan 7 for air intake, the top of the top cover 6 is provided with an air intake filter 8 for dust prevention, the side of the top cover 6 is provided with a detachable side plate 9, the inside of the side plate 9 is provided with an air exhaust fan 10 for exhaust, and the side of the side plate 9 is provided with an air exhaust filter 11 connected to the air exhaust cylinder 5; the design of the air intake filter 8 can effectively prevent large dust particles (such as hair and lint) from entering the purifier, and the air exhaust fan 10 is provided with two symmetrical sets, which can improve the overall working efficiency of the purifier and enhance the purification capacity.

[0046] Working Principle: This type of air purifier operates in the following ways: First, during normal operation, the circulating air enters the purifier under the action of the intake fan 7. The intake filter 8 filters and removes large particles of dust (such as hair and lint). When the air enters the purification cylinder 4, it is purified by the filter element 13. The filter 1302 has a multi-layer design, consisting of a pre-filter, a HEPA filter, an activated carbon layer, and an additional layer. The pre-filter filters large particles such as dust and hair, the HEPA filter efficiently filters PM2.5, bacteria, and other particles, the activated carbon layer adsorbs harmful gases such as formaldehyde and odors, and the additional layer is an antibacterial layer. After a series of purification processes, organic gases are removed, and the purified gas is accelerated and discharged to the outside through the exhaust fan 10 from the exhaust duct 5.

[0047] Secondly, due to the long-term use of filter element 13, its surface is prone to adsorbing particulate matter. At this time, it is necessary to carry out effective dust removal to enhance its practical value. When the dust removal operation starts, the control limit disc 1901 rotates, which will drive the active rod 1902 to rotate inward, thereby driving the sector disc 1903 to move. Since the sector disc 1903 is provided with a rotating shaft for limiting the rotation of the sector disc 1903 at the end away from the active rod 1902, the sector disc 1903 will rotate inward, driving the sector abutment 1904 to form an enclosing structure, thereby providing a lifting effect on the abutment cone 1304 and indirectly increasing the height of filter element 13.

[0048] Next, since the drive gear 18 and the arc rack 1202 form a meshing connection structure, when the drive gear 18 transmits power, it will drive the rotating ring 1201 to rotate. The limiting protrusion 1203 at the top of the rotating ring 1201 will slide into the arc groove opened inside the limiting ring 1204, thereby driving the limiting ring 1204 to rotate. The brush 1206 on the limiting ring 1204 can clean the dust and particles adsorbed on the filter element 13, so that they fall into the dust collection arc groove 14, giving it a self-cleaning function and improving its self-cleaning ability.

[0049] Then, the particles swept down by the dust removal mechanism 12 can slide from the dust collection arc groove 14 to the dust collection cylinder 16, and the dust collection cylinder 16 corresponds to the individual partition groove 301, which can effectively collect the particles; the design of the dustproof cylinder 15 can enhance the air circulation while preventing the particles on the dust collection arc groove 14 from entering it; at the same time, if a lot of particles are adsorbed on the surface of the dust collection arc groove 14, disinfectant can be poured into the inner wall of the purification cylinder 4, and the disinfectant will flow from the dust collection arc groove 14 into the dust collection cylinder 16, and finally be collected by the partition groove 301, which can effectively clean the particles adsorbed on the surface of the dust collection arc groove 14;

[0050] Meanwhile, when the dust collection tray 3 needs to be disassembled, the telescopic spring 201 is engaged, which drives the roller 202 to slide, causing the main support rod 204 and the secondary support rod 205 to press down, causing the support plate 206 to descend and remove its supporting function on the dust collection tray, thereby enabling the dust collection tray 3 to be easily disassembled. The dust collection tray 3 is provided with a detachable partition groove 301. The partition plate 302 has a rotating structure, which can realize the function of separate cleaning and collection of dust and particulate matter adsorbed on the filter element 13, preventing excessive accumulation of dust and particulate matter, thereby causing pollution to the inside of the purifier through the dust removal cylinder 16.

[0051] Finally, when the filter element 13 is used for a long time, it needs to be replaced. The filter screen 1302 can be easily disassembled and replaced by the buckle of the lifting locking column 1303 and the slot opened on the connecting disc 1301.

[0052] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
