Description

Technical Field

[0001] This utility model relates to the field of air purification technology, and in particular to an air purification device with multi-layer circulating filtration. Background Technology

[0002] Air pollution refers to the phenomenon where the concentration of pollutants in the atmosphere reaches a harmful level, thereby damaging the ecosystem and the conditions for normal human survival and development, and causing harm to people or things. Because air pollution affects the balance of the Earth-atmosphere system and affects human health, it is necessary to keep the atmosphere in a clean and relatively balanced and stable state. This requires the use of air purification devices to purify the polluted air.

[0003] Existing technologies, such as Chinese Patent Publication No. CN215962643U, disclose an air purification device with multi-layer circulating filtration, including a ring-shaped connecting pipe. An air inlet pipe is fixedly connected to the outer wall of the connecting pipe, and an air outlet pipe is fixedly connected to the outer wall of the connecting pipe at a position symmetrical to the air inlet pipe. Both the air inlet and outlet pipes are connected to the connecting pipe. The advantages of this invention are: during use, air can be introduced into the connecting pipe through the air inlet pipe. The air is filtered by a second filter plate and a first filter plate in the connecting pipe before being discharged. Some unfiltered air continues to be filtered in the connecting pipe, while impurities left by the second filter plate are pushed into the collection groove of the collection box by the subsequent airflow. Simultaneously, the inclined baffle prevents them from being pushed back into the connecting pipe, thus preventing a large amount of residual impurities from affecting its use. However, this invention is not convenient for adjusting and controlling the purification time according to the actual air quality, resulting in insufficient applicability.

[0004] To address the issue that air purification devices cannot easily adjust the purification time according to air quality, existing equipment often uses a fixed time between air entering and leaving the purification device. When the air quality is good, an excessively long purification time will lead to a decrease in purification efficiency, while when the air quality is poor, an excessively short purification time will lead to a weakening of the purification effect. Therefore, improvements are needed. Utility Model Content

[0005] The purpose of this invention is to solve the problem that existing air purification devices are not convenient for adjusting the purification time according to air quality, and to propose an air purification device with multi-layer circulating filtration.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: an air purification device with multi-layer circulating filtration, comprising a purification box, an air inlet, an intake fan, an air outlet, and a filtration mechanism. The air inlet is located on the top surface of the purification box, the intake fan is fixedly installed on the surface of the air inlet, the air outlet is located on the bottom surface of the purification box, the filtration mechanism is disposed on the inner wall of the purification box, the filtration mechanism includes a filter layer, the filter layer is fixedly connected to the inner wall of the purification box, a motor is fixedly installed on the surface of the purification box, a screw is fixedly connected to the output end of the motor, a rack plate is threadedly connected to the surface of the screw, a limit rod is fixedly connected to the surface of the purification box, the rack plate is slidably connected to the surface of the limit rod, a rotating shaft is rotatably connected to the inner wall of the purification box, a gear is fixedly connected to the surface of the rotating shaft, the gear meshes with the surface of the rack plate, an adjusting plate is fixedly connected to the surface of the rotating shaft, an extension plate is slidably connected to the surface of the adjusting plate, and a cleaning roller is fixedly connected to the surface of the extension plate.

[0007] Furthermore, the number of filter layers is multiple and evenly distributed, and the adjusting plate, expanding plate and cleaning roller are all arranged inside the purification box, with the cleaning roller cooperating with the filter layers.

[0008] Furthermore, the number of the rotating shaft, gear, adjusting plate, extension plate and cleaning roller are all in two sets, and the number of the rotating shaft, gear, adjusting plate, extension plate and cleaning roller in each set are multiple, and the two sets of adjusting plates are arranged alternately.

[0009] Furthermore, the inner wall of the purification box is provided with a guide groove, and a guide rod is fixedly connected to the surface of the expansion plate, and the guide rod is slidably connected to the surface of the guide groove.

[0010] Furthermore, the surface of the purification box is provided with a collection mechanism, which includes a collection trough. The collection trough is opened on the surface of the purification box. There are two sets of collection troughs, and each set contains multiple collection troughs. The collection trough cooperates with the cleaning roller. The collection box is fixedly installed on the surface of the purification box.

[0011] Furthermore, the collection trough is connected to the collection box, and a baffle is slidably connected to the surface of the collection trough, with an inclined groove formed on the surface of the baffle.

[0012] Furthermore, a spring is fixedly connected to the surface of the baffle, and the end of the spring away from the baffle is fixedly connected to the surface of the collection tank.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, by setting up a filtration mechanism, the intake fan is activated to draw air into the purification chamber through the air inlet. Multiple sets of filter layers are used for adsorption and purification, and the air is then discharged through the air outlet. During this process, the time the air stays in the purification chamber can be changed by adjusting the angle of two sets of staggered adjustment plates. Simply start the motor to drive the screw to rotate, causing the rack plate to slide up and down along the limit rod, which in turn drives the gear and shaft to rotate, thereby adjusting the angle of the adjustment plates. During adjustment, the guide rod slides along the guide groove, allowing the extension plate to extend or retract accordingly. Simultaneously, a cleaning roller cleans the surface of the filter layers to prevent clogging. By setting up a filtration mechanism, multiple sets of filter layers are used to adsorb and purify the air, and the time the air stays in the purification chamber can be changed as needed. When the air quality is good, it can pass through quickly to improve filtration efficiency; when the air quality is poor, its residence time can be increased to improve the filtration effect. This effectively enhances the applicability of the equipment.

[0015] 2. In this utility model, by setting up a collection mechanism, the dust and foreign objects cleaned by the cleaning roller are pushed into the collection troughs on both sides. When their weight reaches a certain level, they will drive the baffle downward and compress the spring, so that the collection trough is connected to the collection box. The dust and foreign objects are guided into the collection box under the action of the inclined trough. Then the spring rebounds, driving the baffle to reset and continuing to isolate the collection trough and the collection box. By setting up a collection mechanism, the dust and foreign objects cleaned by the cleaning roller can be properly collected in the collection box, which is convenient for subsequent centralized processing, thus effectively improving the convenience of the equipment.

[0023] Please see Figures 1-5 This utility model provides a technical solution: an air purification device with multi-layer circulating filtration, including a purification box 1, an air inlet 2, an air intake fan 3, an air outlet 4, and a filtration mechanism 5. The air inlet 2 is opened on the top surface of the purification box 1, the air intake fan 3 is fixedly installed on the surface of the air inlet 2, the air outlet 4 is opened on the bottom surface of the purification box 1, and the filtration mechanism 5 is set on the inner wall of the purification box 1.

[0024] The following section will explain the specific setup and function of its filtration mechanism 5 and collection mechanism 6.

[0025] In this embodiment: the filtration mechanism 5 includes a filter layer 501, which is fixedly connected to the inner wall of the purification box 1. A motor 502 is fixedly installed on the surface of the purification box 1. A screw 503 is fixedly connected to the output end of the motor 502. A rack plate 504 is threadedly connected to the surface of the screw 503. A limit rod 505 is fixedly connected to the surface of the purification box 1. The rack plate 504 is slidably connected to the surface of the limit rod 505. A rotating shaft 506 is rotatably connected to the inner wall of the purification box 1. A gear 507 is fixedly connected to the surface of the rotating shaft 506. The gear 507 is meshed with the surface of the rack plate 504. An adjusting plate 508 is fixedly connected to the surface of the rotating shaft 506. An extension plate 509 is slidably connected to the surface of the adjusting plate 508. A cleaning roller 510 is fixedly connected to the surface of the extension plate 509.

[0026] The effects achieved by the above components are as follows: The filter layer 501 is set to facilitate the adsorption and purification of air. The motor 502 is started to drive the screw 503 to rotate, so that the rack plate 504 slides up and down along the limit rod 505, which drives the gear 507 and the rotating shaft 506 to rotate, thereby realizing the adjustment of the angle of the adjusting plate 508. The adjusting plate 508 is set to cooperate with the extension plate 509 to control the air circulation time in the purification box 1. The extension plate 509 is set to extend or retract with the rotation of the adjusting plate 508. The cleaning roller 510 is set to clean the surface of the filter layer 501 by sliding the extension plate 509 when the adjusting plate 508 rotates, so as to avoid the filter layer 501 from becoming clogged.

[0027] Specifically, the filter layers 501 are in multiple sets and are evenly distributed. The adjusting plate 508, the expansion plate 509 and the cleaning roller 510 are all located inside the purification box 1. The cleaning roller 510 cooperates with the filter layers 501.

[0028] The effect achieved by the above components is to increase the filtration effect by setting multiple filter layers 501.

[0029] Specifically, there are two sets of rotating shaft 506, gear 507, adjusting plate 508, extension plate 509 and cleaning roller 510. Each set contains multiple sets of rotating shaft 506, gear 507, adjusting plate 508, extension plate 509 and cleaning roller 510. The two sets of adjusting plates 508 are arranged alternately.

[0030] The effect achieved by the above components is as follows: setting two sets of staggered adjustment plates 508 is to change the air circulation time in the purification box 1 by means of blocking and guiding airflow. Setting multiple adjustment plates 508 in each set is to facilitate the use of multiple filter layers 501 to increase the purification time of air in the purification box 1.

[0031] Specifically, the inner wall of the purification box 1 is provided with a guide groove 511, and a guide rod 512 is fixedly connected to the surface of the expansion plate 509. The guide rod 512 is slidably connected to the surface of the guide groove 511.

[0032] The effect achieved by the above components is that the guide groove 511 and the guide rod 512 are set so that the guide rod 512 slides along the guide groove 511 during the rotation of the adjustment plate 508, so that the extension plate 509 can be stably extended or retracted accordingly.

[0033] Specifically, the surface of the purification box 1 is provided with a collection mechanism 6, which includes a collection trough 61. The collection trough 61 is opened on the surface of the purification box 1. There are two sets of collection troughs 61, and each set contains multiple collection troughs 61. The collection trough 61 cooperates with the cleaning roller 510. A collection box 62 is fixedly installed on the surface of the purification box 1.

[0034] The effects achieved by the above components are as follows: the two sets of collection grooves 61 are set so that when the cleaning roller 510 slides and cleans the surface of the filter layer 501, the cleaned dust and foreign objects will be pushed into the collection grooves 61 on both sides. Each set of collection grooves 61 is set in multiple ways to match multiple sets of filter layers 501. The collection box 62 is set to properly collect the cleaned dust and foreign objects.

[0035] Specifically, the collection trough 61 is connected to the collection box 62, and a baffle 63 is slidably connected to the surface of the collection trough 61. An inclined groove 64 is opened on the surface of the baffle 63.

[0036] The effects achieved by the above components are as follows: the baffle 63 is provided to facilitate the isolation of the collection trough 61 and the collection box 62 during daily use, and the inclined groove 64 is provided to facilitate the guidance of dust and foreign objects into the collection box 62.

[0037] Specifically, a spring 65 is fixedly connected to the surface of the baffle 63, and the end of the spring 65 away from the baffle 63 is fixedly connected to the surface of the collection tank 61.

[0038] The effect achieved by the above components is as follows: the spring 65 is set so that when a certain amount of dust and foreign objects accumulate in the collection tank 61, the baffle 63 is pressed down and the spring 65 is pressed under its gravity, so that the dust and foreign objects are guided into the collection box 62 by the inclined groove 64. Then, under the rebound action of the spring 65, the baffle 63 is reset and continues to isolate the collection tank 61 and the collection box 62.

[0039] Working principle: By setting up the filter mechanism 5 and starting the intake fan 3, air is drawn into the purification chamber 1 through the air inlet 2. Multiple filter layers 501 adsorb and purify the air, which is then discharged through the air outlet 4. During this process, the time the air stays in the purification chamber 1 can be changed by adjusting the angle of the two sets of staggered adjusting plates 508. Simply start the motor 502 to drive the screw 503 to rotate, causing the rack plate 504 to slide up and down along the limit rod 505, which in turn drives the gear 507 and the rotating shaft 506 to rotate, thereby adjusting the angle of the adjusting plates 508. During the adjustment process, the guide rod 512 slides along the guide groove 511, allowing the extension plate 509 to extend or retract accordingly. At the same time, the cleaning roller 510 cleans the surface of the filter layer 501 to prevent clogging. By setting up the filtration mechanism 5, multiple sets of filter layers 501 are used to adsorb and purify the air. The time that the air stays in the purification box 1 can be changed as needed. When the air quality is good, it can pass through quickly to improve the filtration efficiency. When the air quality is poor, its residence time can be increased to improve the filtration effect. This effectively improves the applicability of the equipment.

[0040] Furthermore, by setting up a collection mechanism 6, the dust and foreign objects cleaned by the cleaning roller 510 are pushed into the collection troughs 61 on both sides. When their weight reaches a certain level, they will drive the baffle 63 downward and press the spring 65, connecting the collection trough 61 with the collection box 62. The dust and foreign objects are guided into the collection box 62 under the action of the inclined chute 64. Then the spring 65 rebounds, driving the baffle 63 to reset, continuing to isolate the collection trough 61 and the collection box 62. By setting up the collection mechanism 6, the dust and foreign objects cleaned by the cleaning roller 510 can be properly collected in the collection box 62, which is convenient for subsequent centralized processing, thus effectively improving the convenience of the equipment.
