Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of air odor removal devices, in particular to an odor purification filtering device. BACKGROUND

[0002] Gaseous pollutants are formed by objects or liquids volatilizing at high temperatures and floating in the air, often with an odor, which needs to be purified and filtered by an air purifier to remove harmful gas molecules and floating objects in the air, achieving purification and deodorization effect. However, the existing odor polymerization purification filtering device still has some problems in use.

[0003] The Chinese invention patent with publication number "CN118253183A" specifically discloses an odor polymerization purification filtering device, which, by setting a flow guide mechanism, allows external air to accumulate in the filter ball before being filtered and introduced into the box, performs deodorization and purification during the accumulation process in the filter ball, prolongs the contact time between air and deodorizing agent, improves the deodorization effect, and sets first and second spiral flow guide plates in the filter ball. The first spiral flow guide plate drives air to flow spirally, prolongs the air flow distance, and allows air to flow spirally in the first spiral flow guide plate and accumulate in the filter ball, which combines with the deodorizing agent to deodorize, facilitates sufficient contact between air and deodorizing agent, and improves the deodorization effect. At the same time, the second spiral flow guide plate is driven to rotate by the air flow force, which changes the position of the air outlet to improve the randomness of air introduction and facilitate mixing of the deodorizing agent and air, thereby improving the deodorization effect. However, due to the fixed setting of the spray pipe, when a large amount of air passes through the spray pipe, the amount of deodorizing agent sprayed by the spray pipe cannot be adjusted adaptively because the deodorizing agent cannot adapt to the change in the amount of air passing through when the air flow rate is high. Therefore, the relative content of deodorizing agent in the air is low when the air flow rate is high, which affects the air purification quality. Therefore, we propose an odor purification filtering device and method to solve the above problems. SUMMARY

[0004] The present application aims to provide an odor purification filtering device and method to solve the problems raised in the background.

[0005] To achieve the above-mentioned purpose, the present application provides the following technical solution: an odor purification filtering device, comprising:

[0006] A box, the inside of the box is provided with a fan;

[0007] An air flow grid is arranged around the box;

[0009] The fan is used to draw outside air into the box from the airflow grid and exhaust it from the vent. The device also includes a flow guide component installed on the airflow grid for air circulation and deodorization.

[0010] The diversion components include:

[0011] An outer filter ring, which is located to the outside and whose outer periphery is used for air intake;

[0012] An inner filter ring is located inside the outer filter ring and is circular with it. Air enters the interior through the outer circumference of the inner filter ring and is introduced into the housing.

The self-expanding adjustment plate assembly is provided with a through-hole, and an atomizing nozzle is provided in the through-hole to spray deodorizing agent into the through-hole and between the self-expanding adjustment plate assemblies at the same time.

[0014] A spiral impeller is connected to an outer filter ring via a drive mechanism. The spiral impeller is used to convert the kinetic energy of the air passing through it into the kinetic energy of the rotation of the outer filter ring.

[0015] An elastic component is connected to the outer filter ring via a transmission mechanism, allowing the outer filter ring to return to its original position.

[0016] Preferably, the self-expanding adjustment plate assembly includes:

[0024] The atomizing nozzle one and atomizing nozzle two can completely cover the opening one and opening two to spray the deodorizing agent, and at the same time, the atomizing nozzle one and atomizing nozzle two can spray the deodorizing agent outward.

[0025] Preferably, the inner wall of the inner filter ring is equipped with a plurality of guide plates, the guide plates being in the shape of a vortex line gradually approaching the center of the inner filter ring from the outside to the inside, and forming a vortex line-shaped airflow passage between the guide plates.

[0026] The inner filter ring and the guide plate are equipped with an outer fixed circular plate at the ends away from the airflow grid plate, which closes the interior of the inner filter ring and the space between the inner filter ring and the outer filter ring, and the outer fixed circular plate is in contact with the end of the outer filter ring.

[0027] The inner filter ring and the end of the guide plate near the airflow grid are equipped with a connecting ring plate that seals the space between the inner filter ring and the outer filter ring.

[0028] Preferably, a plurality of strip-shaped shovels are installed on the outer circumference of the outer fixed circular plate and the connecting ring plate, and the strip-shaped shovels are in contact with the outer side of the outer filter ring;

[0029] The cross-section of the strip-shaped shovel is triangular, and one side of the strip-shaped shovel has an arc-shaped structure corresponding to the outer side of the outer filter ring.

[0030] Preferably, a driven ring is installed at the end of the outer filter ring near the airflow grid plate, and the driven ring passes through the connecting ring plate and is rotatably connected to the connecting ring plate;

[0031] Multiple transmission fixing rods are installed on the inner side of the driven ring, and a driving ring is installed on the inner end of the transmission fixing rods. The helical impeller is installed on the inner side of the driving ring.

[0032] Preferably, the middle of the connecting ring plate is connected to the interior of the inner filter ring, the inner diameter of the driving ring is the same as the inner diameter of the connecting ring plate, and the inner filter ring, outer filter ring, driven ring, and driving ring are coaxial, with the end of the driving ring away from the airflow grid contacting the connecting ring plate.

[0033] Preferably, the connecting ring plate is equipped with a plurality of circumferentially arranged spring bars on the side near the airflow grid plate, each spring bar being positioned between two transmission fixing rods and spaced apart from the transmission fixing rods;

[0034] The elastic component includes a return spring, which is installed between the spring bar and the transmission fixed rod. One end of the return spring is installed on the side of the spring bar, and the other end of the return spring is installed on the side of the transmission fixed rod.

[0035] Preferably, the ends of the strip-shaped shovels near the airflow grid are jointly mounted with a mounting base, and the outer side of the driven ring is in circular contact with the inner side of the mounting base. The mounting base is in contact with the ends of the driven ring and the driving ring near the airflow grid, and the middle of the mounting base is connected to the middle of the driving ring and communicates with the inside of the box.

[0036] The outer side of the mounting base is installed with the airflow grid plate, and the end of the mounting base near the box is flush with the inner side of the airflow grid plate. The outer periphery of the end of the mounting base near the box has a medicine storage cavity with an annular opening, and a screw plug is detachably connected to the opening of the medicine storage cavity.

[0037] Preferably, the steps include:

[0038] Step 1: Under the action of the fan inside the cabinet, air enters the interior of the cabinet from the airflow guide assembly and is discharged from the exhaust vent.

[0039] Step 2: Air enters from the outside of the outer filter ring between the outer and inner filter rings, passes through the self-expanding adjustment plate assembly or the opening, and then passes through the inner filter ring. Under the action of the atomizing nozzle, the deodorizing agent can come into contact with the air to purify it.

[0040] Step 3: The air passing through the inner filter ring is guided by the baffle plate to form a swirling flow in the middle of the inner filter ring, so that the air and the deodorizing agent carried in the air can be mixed in a swirling flow, and then pass through the drive ring and enter the interior of the box through the mounting base.

[0041] Step 4: The air passing through the driving ring can drive the spiral impeller to rotate, and through the driving ring and the transmission fixed rod, it drives the driven ring to rotate synchronously, thereby driving the outer filter ring.

[0042] Step 5: Driven by the outer filter ring, the outer sliding arc plate and the inner sliding arc plate slide relative to each other, and the outer sliding arc plate and the inner and outer filter rings rotate relative to each other. At this time, the outer sliding arc plate and the inner sliding arc plate tilt as a whole. At this time, the spacing and length between the self-expanding adjustment plate assemblies change, and there is a large area of ​​overlap between the outer filter ring and the inner filter ring in the straight direction of the self-expanding adjustment plate assemblies, forming a multi-layer purification effect.

[0043] Step 6: When the outer sliding arc plate and the inner sliding arc plate slide relative to each other, the relative movement between the first and second openings reduces the overlapping portion, thereby reducing the amount of airflow near the inner filter ring.

[0044] Step 7: Under the action of the return spring, the outer sliding arc plate and the inner sliding arc plate can extend and retract back and forth, creating an effect of agitating the air.

[0045] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0046] 1. This odor purification and filtration device drives the outer filter ring to rotate via a spiral impeller, and simultaneously causes the self-expanding adjustment plate assembly to rotate and expand / contract. The gap between the self-expanding adjustment plate assemblies changes accordingly. When the incoming airflow velocity is high, the outer filter ring rotates to a relatively greater extent, and the gap between the self-expanding adjustment plate assemblies is narrower, allowing the deodorizing agent sprayed from the atomizing nozzle to penetrate the air better, thus ensuring the air purification effect. At the same time, the increased length of the gap between the self-expanding adjustment plate assemblies prolongs the airflow path, thereby increasing the contact time between the air and the deodorizing agent.

[0047] 2. This odor purification and filtration device, through the fluctuation of the pumped airflow, causes the self-expanding adjustment plate assembly to swing back under the action of the elastic component. This agitates the airflow between the outer and inner filter rings and the atomized deodorizing agent, causing them to move irregularly, thereby improving the purification effect.

[0059] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0060] Example: Figures 1-9 As shown, the present invention provides an odor purification and filtration device, comprising:

[0061] Box 1, with a fan installed inside the box 1;

[0062] Airflow baffle 2, which is disposed around the perimeter of the housing 1;

[0063] Vent 3, which is installed on the top of housing 1;

[0064] The fan is used to draw outside air into the housing 1 from the airflow grid 2 and exhaust it from the exhaust port 3. The device also includes a guide component 4 installed on the airflow grid 2 for air circulation and deodorization.

[0065] The flow guiding component 4 includes:

[0066] An outer filter ring 411 is located in the outside environment, and the outer periphery of the outer filter ring 411 is used for air intake.

[0067] The inner filter ring 402 is located inside the outer filter ring 411 and is circular. Air enters the interior through the outer periphery of the inner filter ring 402 and is introduced into the housing 1.

[0068] The self-expanding adjustment plate assembly 430 has its two ends hinged to the inner wall of the outer filter ring 411 and the outer wall of the inner filter ring 402, respectively. The self-expanding adjustment plate assembly 430 is provided with a through-hole, and an atomizing nozzle is provided in the through-hole to spray deodorizing agent into the through-hole and between the self-expanding adjustment plate assemblies 430 at the same time.

[0069] The spiral impeller 414 is connected to the outer filter ring 411 in a driving connection. The spiral impeller 414 is used to convert the kinetic energy of the air passing through into the kinetic energy of the rotation of the outer filter ring 411.

[0070] An elastic component is connected to the outer filter ring 411 for repositioning.

[0071] It should be noted that the operation of the above-mentioned fan (not shown in the figure) can generate a wind suction effect. The air entering the housing 1 first passes through the outer filter ring 411 and enters between the outer filter ring 411 and the inner filter ring 402, and then enters the housing 1 through the inside of the inner filter ring 402.

[0072] As air enters the housing 1, it passes through the spiral impeller 414, which drives the impeller 414 to rotate. Through the transmission of the spiral impeller 414, the outer filter ring 411 rotates relative to the inner filter ring 402, which in turn drives the self-expanding adjustment plate assembly 430 to rotate and expand simultaneously. When the self-expanding adjustment plate assembly 430 rotates, the gaps between the self-expanding adjustment plate assemblies 430 change. When the airflow velocity is high, the kinetic energy generated by the spiral impeller 414 is relatively high, and the degree of rotation of the outer filter ring 411 is relatively large. At this time, the gaps between the self-expanding adjustment plate assemblies 430 are narrower, which allows the deodorizing agent sprayed from the atomizing nozzle to penetrate the air better, thereby ensuring the air purification effect. At the same time, the length of the gaps between the self-expanding adjustment plate assemblies 430 increases, extending the airflow path and allowing the air to contact the deodorizing agent for a longer time, thus avoiding the situation where the air purification is incomplete due to the high airflow velocity.

[0073] In real life, the airflow is constantly fluctuating. Therefore, under the action of the elastic component, the self-expanding adjustment plate assembly 430 swings back. The swing of the self-expanding adjustment plate assembly 430 can agitate the airflow between the outer filter ring 411 and the inner filter ring 402 as well as the atomized deodorizing agent, causing them to move irregularly, thereby improving the purification effect.

[0074] On the other hand, the self-expanding adjustment plate assembly 430 includes:

[0075] An outer sliding arc plate 431 is arc-shaped, and one end of the outer sliding arc plate 431 is hinged to the outer wall of the inner filter ring 402.

[0076] The inner sliding arc plate 432 is arc-shaped and has the same curvature as the outer sliding arc plate 431. One end of the inner sliding arc plate 432 is hinged to the inner wall of the outer filter ring 411.

[0077] The other end of the inner sliding arc plate 432 is slidably connected to the other end of the outer sliding arc plate 431 and extends into the interior of the outer sliding arc plate 431;

[0078] The outer sliding arc plate 431 and the inner sliding arc plate 432 are arranged in an inclined manner between the inner filter ring 402 and the outer filter ring 411.

[0079] It should be noted that by using an outer sliding arc plate 431 and an inner sliding arc plate 432 with the same curvature, the outer sliding arc plate 431 and the inner sliding arc plate 432 can slide relative to each other. The inclined design makes the gap length between the self-expanding adjustment plate assembly 430 longer, thereby making the air flow path longer and thus making the purification effect better.

[0080] Specifically, the outer sliding arc plate 431 has a through opening 433, and the inner sliding arc plate 432 has a through opening 434.

[0081] The first opening 433 and the second opening 434 are the same size, and when the outer filter ring 411 is in its original position, the first opening 433 and the second opening 434 completely overlap.

[0082] The inner wall of the first opening 433 is provided with an atomizing nozzle 435, and the inner wall of the second opening 434 is provided with an atomizing nozzle 436.

[0083] The atomizing nozzle 435 and atomizing nozzle 436 can completely cover the openings 433 and 434 to spray deodorizing agent, while the atomizing nozzles 435 and 436 can spray deodorizing agent outwards.

[0084] It should be noted that by using overlapping ventilation openings 433 and 434, the air between the outer filter ring 411 and the inner filter ring 402 can circulate during the oscillation process, thereby improving the mixing effect. When relative sliding occurs between the outer sliding arc plate 431 and the inner sliding arc plate 432, the overlapping part of openings 433 and 434 on the outer sliding arc plate 431 becomes smaller, which reduces the aperture available for airflow. As a result, air mainly enters the interior of the inner filter ring 402 through the gap between the self-expanding adjustment plate assemblies 430.

[0085] On the other hand, a plurality of guide plates 406 are installed on the inner wall of the inner filter ring 402. The guide plates 406 are in the shape of a vortex line that gradually approaches the middle of the inner filter ring 402 from the outside to the inside, and a vortex line-shaped airflow passage is formed between the guide plates 406.

[0086] The inner filter ring 402 and the guide plate 406 are equipped with an outer fixed circular plate 403 at the ends away from the airflow grid plate 2, which encloses the interior of the inner filter ring 402 and the space between the inner filter ring 402 and the outer filter ring 411, and the outer fixed circular plate 403 is in contact with the end of the outer filter ring 411.

[0087] The inner filter ring 402 and the guide plate 406 near the airflow grid plate 2 are equipped with a connecting ring plate 407 that seals the space between the inner filter ring 402 and the outer filter ring 411.

[0088] It should be noted that the vortex-shaped guide vane 406 extends the airflow path, thereby further extending the air residence time. Under the guidance of the guide vane 406, the air and the deodorizing agent carried in the air are mixed in a swirling motion within the inner filter ring 402, resulting in more uniform air purification. Furthermore, the swirling motion causes the air to move in a spiral, further increasing the air residence time and thus improving the air purification effect.

[0089] On the other hand, a plurality of strip-shaped shovels 404 are installed on the outer circumference of the outer fixed circular plate 403 and the connecting ring plate 407, and the strip-shaped shovels 404 are in contact with the outer side of the outer filter ring 411.

[0090] The cross-section of the strip-shaped shovel 404 is triangular, and one side of the strip-shaped shovel 404 has an arc-shaped structure corresponding to the outer side of the outer filter ring 411.

[0091] It should be noted that when the outer filter ring 411 rotates relative to the outer filter ring 411, the strip shovel 404 remains stationary. At this time, the strip shovel 404 can shovel away the debris outside the outer filter ring 411, effectively preventing the outer filter ring 411 from becoming clogged. Under the back-and-forth swinging action of the outer filter ring 411, the debris outside it can be thrown off.

[0092] Furthermore, a driven ring 413 is installed at the end of the outer filter ring 411 near the airflow grid plate 2. The driven ring 413 passes through the connecting ring plate 407 and is rotatably connected to the connecting ring plate 407.

[0093] Multiple transmission fixing rods 412 are installed on the inner side of the driven ring 413, and a driving ring 415 is installed on the inner end of the transmission fixing rods 412. The spiral impeller 414 is installed on the inner side of the driving ring 415.

[0094] It should be noted that the driven ring 413 drives the outer filter ring 411 to rotate, and the driven ring 413 drives the transmission fixed rod 412 to rotate. The driven ring 415 drives the transmission fixed rod 412 to rotate, and the driven impeller 414 drives the drive ring 415 to rotate.

[0095] Furthermore, the middle of the connecting ring plate 407 is connected to the interior of the inner filter ring 402, the inner diameter of the driving ring 415 is the same as the inner diameter of the connecting ring plate 407, and the inner filter ring 402, the outer filter ring 411, the driven ring 413, and the driving ring 415 are coaxial. The end of the driving ring 415 away from the airflow grid plate 2 is in contact with the connecting ring plate 407.

[0096] Furthermore, a plurality of circumferentially arranged spring bars 405 are installed on the side of the connecting ring plate 407 near the airflow grid plate 2. Each spring bar 405 is located between two transmission fixing rods 412 and is spaced apart from the transmission fixing rods 412.

[0097] The elastic component includes a return spring 420, which is installed between the spring bar post 405 and the transmission fixing rod 412. One end of the return spring 420 is installed on the side of the spring bar post 405, and the other end of the return spring 420 is installed on the side of the transmission fixing rod 412.

[0098] It should be noted that under the action of the spring force of the return spring 420, the transmission fixing rod 412 can be pushed relative to each other, so that the transmission fixing rod 412 can automatically return to its original position.

[0099] Furthermore, the strip-shaped shovel plate 404 is mounted with a mounting base 401 at the end near the airflow grid plate 2, and the outer side of the driven ring 413 is in circular contact with the inner side of the mounting base 401. The mounting base 401 is in contact with the ends of the driven ring 413 and the driving ring 415 near the airflow grid plate 2, and the middle of the mounting base 401 is connected to the middle of the driving ring 415 and communicates with the inside of the box 1.

[0100] The outer side of the mounting base 401 is installed with the airflow grid plate 2. The end of the mounting base 401 near the box 1 is flush with the inner side of the airflow grid plate 2. The outer periphery of the end of the mounting base 401 near the box 1 is provided with a medicine storage cavity 440 with an annular opening. A screw plug 450 is detachably connected to the opening of the medicine storage cavity 440.

[0101] It should be noted that by opening the screw plug 450, deodorizing agent can be injected into the medicine storage chamber 440. The deodorizing agent in the medicine storage chamber 440 can flow into the atomizing nozzle 435 and the atomizing nozzle 436 (the specific pipelines are not shown in the figure).

[0102] Includes the following steps:

[0103] Step 1: Under the action of the fan inside the housing 1, air enters the interior of the housing 1 through the air guide assembly 4 and is discharged from the exhaust vent 3.

[0104] Step 2: Air enters from the outside of the outer filter ring 411 between the outer filter ring 411 and the inner filter ring 402, and passes through the self-expanding adjustment plate assembly 430 or the opening through the inner filter ring 402. Under the action of the atomizing nozzle, the deodorizing agent can come into contact with the air to purify the air.

[0105] Step 3: The air passing through the inner filter ring 402 is guided by the guide plate 406 to form a swirling flow in the middle of the inner filter ring 402, so that the air and the deodorizing agent carried in the air can be mixed in a swirling flow, and then pass through the drive ring 415 and enter the interior of the housing 1 through the mounting base 401.

[0106] Step 4: The air passing through the driving ring 415 can drive the spiral impeller 414 to rotate, and through the driving ring 415 and the transmission fixed rod 412, drive the driven ring 413 to rotate synchronously, thereby driving the outer filter ring 411.

[0107] Step 5: Driven by the outer filter ring 411, the outer sliding arc plate 431 and the inner sliding arc plate 432 slide relative to each other, and the outer sliding arc plate 431 and the inner sliding arc plate 432 rotate relative to the inner filter ring 402 and the outer filter ring 411. At this time, the outer sliding arc plate 431 and the inner sliding arc plate 432 tilt as a whole. At this time, the spacing and length between the self-expanding adjustment plate assemblies 430 change, and there is a large area of ​​overlap between the outer filter ring 411 and the inner filter ring 402 in the straight direction of the self-expanding adjustment plate assemblies 430, forming a multi-layer purification effect.

[0108] Step 6: When the outer sliding arc plate 431 and the inner sliding arc plate 432 slide relative to each other, the relative movement between the first opening 433 and the second opening 434 reduces the overlapping part, thereby reducing the amount of airflow near the inner filter ring 402.

[0109] Step 7: Under the action of the return spring 420, the outer sliding arc plate 431 and the inner sliding arc plate 432 can extend and retract back and forth, thus creating an effect of agitating the air.

[0110] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.

9. A method of using the odor purification and filtration device according to claim 8, characterized in that, Includes the following steps: Step 1: Under the action of the fan inside the housing (1), the air enters the interior of the housing (1) through the air guide assembly (4) and is discharged from the exhaust port (3); Step 2: Air enters from the outside of the outer filter ring (411) between the outer filter ring (411) and the inner filter ring (402), and passes through the self-expanding adjustment plate assembly (430) or the opening (433, 434) through the inner filter ring (402). Under the action of the atomizing nozzle (435, 436), the deodorizing agent can come into contact with the air to purify the air. Step 3: The air passing through the inner filter ring (402) is guided by the guide plate (406) to form a swirling flow in the middle of the inner filter ring (402), so that the air and the deodorizing agent carried in the air can be mixed in a swirling flow, and then pass through the drive ring (415) and enter the interior of the box (1) through the mounting base (401). Step 4: The air passing through the driving ring (415) can drive the spiral impeller (414) to rotate, and through the driving ring (415) and the transmission fixed rod (412) drive the driven ring (413) to rotate synchronously, so as to drive the outer filter ring (411). Step 5: Driven by the outer filter ring (411), the outer sliding arc plate (431) and the inner sliding arc plate (432) slide relative to each other, and the outer sliding arc plate (431) and the inner sliding arc plate (432) rotate relative to the inner filter ring (402) and the outer filter ring (411). At this time, the outer sliding arc plate (431) and the inner sliding arc plate (432) tilt as a whole. At this time, the spacing and length between the self-expanding adjustment plate assemblies (430) change, and there is a large area of ​​overlap between the outer filter ring (411) and the inner filter ring (402) in the self-expanding adjustment plate assemblies (430), forming a multi-layer purification effect. Step 6: When the outer sliding arc plate (431) and the inner sliding arc plate (432) slide relative to each other, the relative movement between the first opening (433) and the second opening (434) reduces the overlapping part between them, thereby reducing the amount of airflow near the inner filter ring (402). Step 7: Under the action of the spring force of the return spring (420), the outer sliding arc plate (431) and the inner sliding arc plate (432) can generate a back-and-forth swinging motion tendency, and form a stirring effect on the air.
