Description

Technical Field

[0001] The present invention relates to the technical field of air-conditioning vents, and more particularly to an air-conditioning vent control structure. Background Art

[0002] Existing air conditioners use induced draft technology, which can achieve mixing of indoor air with heat-exchanged air before entering the indoor environment, achieving coolness without being cold. When the induced draft is turned off, rapid cooling can be achieved. However, in actual use, the air supply requirements of the air conditioner vary depending on the age and physical condition of the user. In the prior art, the patent document with publication number CN111197808A discloses an induced draft control structure for an air conditioner induced draft vent and an air conditioner. The induced draft control structure includes a fixed ring, a drive ring, a drive mechanism, and a plurality of blades; the fixed ring is fixedly arranged on the induced draft vent of the air conditioner indoor unit. The induced draft vent can not only be fully opened or closed for induced draft, but also the amount of induced draft can be arbitrarily controlled. However, the above structure has the following technical problems when used:

[0003] The existing air vent structure lacks filtering function and lacks a self-cleaning structure for the filtering structure. At the same time, the existing air vent control structure causes the air filtering mode to be relatively single when the air is taken in. It is impossible to flexibly adjust the filtering order and method according to different air quality and usage scenarios, and cannot accurately meet the user's diverse requirements for air quality. The intelligence and applicability are poor. Based on this, the present invention provides an air vent control structure for an air conditioner air vent to solve the technical problems raised in the above background technology.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. In the present invention, the sequencing system can adjust the state and order of the air flow through the four filter elements at the air inlet according to actual needs. When the return air fan is working, the air passes through the filter element into the clean air exhaust duct, and then enters the return air chamber through the soft duct. The solenoid valve in the return air chamber can control the on and off of each return air hose according to the instructions of the microcontroller to adjust the state and order of the air flow. This adjustment method can flexibly adjust the filtering order and method according to different air quality and usage scenarios. Compared with the fixed filtering mode of the existing technology, it can more accurately meet the user's requirements for air quality and improve the intelligence and applicability of the air conditioner.

[0021] 2. The present invention is equipped with four primary filter plates and filter elements with different functions. The primary filter plates include coarse filter plates, fruit carbon filter plates, photocatalyst primary filter plates and electrostatic adsorption filter plates, which can perform multi-stage preliminary filtration on the air entering the air conditioner. The coarse filter plates can intercept larger particles of dust, the fruit carbon filter plates adsorb odors and some harmful gases, the photocatalyst primary filter plates decompose organic matter and bacteria, and the electrostatic adsorption filter plates adsorb tiny particles. Subsequent filter elements such as fine filter cartridges, fruit carbon filter elements, UV sterilization filter elements and odor decomposition filter elements perform fine filtration. Compared with the single primary filtration in the existing technology, this multi-stage filtration method can purify the air more comprehensively, improve air cleanliness, and reduce the burden on subsequent fine filtration.

[0022] 3. The present invention is equipped with a pulse back-cleaning connector and a dust exhaust module. When the primary filter plate and filter element need to be cleaned, back-flushing air cleaning can be achieved through the high-pressure air outlet of the back-cleaning air pump, which can effectively remove accumulated dust and other impurities. During back-flushing cleaning, the dust is blown into the cylinder shell, enters the dust exhaust chamber through the dust exhaust pipe, and then enters the dust discharge cylinder through the dust discharge hole. The sealing screw plug on the dust discharge cylinder can be opened regularly to clean the dust. At the same time, the air outlet connector of the dust discharge cylinder is connected to the return air chamber, so that part of the air can flow back to the air inlet of the air conditioner, ensuring the cleanliness of the interior of the air conditioner, extending the service life of the air conditioner, and solving the problems in the prior art where the filter components are difficult to effectively clean and dust accumulation affects the performance of the air conditioner.

[0023] 4. In the present invention, the air detection module and the microcontroller constitute an "intelligent center". The PM2.5 sensor, gas sensor and temperature and humidity sensor monitor the air parameters in real time. The microcontroller compares the real-time data with the preset threshold value and makes a decision based on the air quality level, temperature and humidity, etc. The PWM signal drives the motor to control the rotation angle of the rotating frame so that the corresponding air inlet hood is aligned with the electric blinds. The double-moving frame motion parameters can also be adjusted according to the degree of pollution. At the same time, the filtration efficiency is calculated based on the data feedback from the motor encoder to achieve closed-loop control of "environmental perception, intelligent decision-making, precise execution, and dynamic optimization".

[0024] 5. In the present invention, the double-moving frame driven by the double-moving components can be synchronously moved up and down and back and forth, and the magnetic rotary cylinder can rotate alternately forward and reverse. The movement of the double-moving frame disturbs the airflow at multiple angles, increases the probability of contact between impurities and the filter element, improves the filtration efficiency, and makes the filtration load on the surface of the filter element evenly distributed, thereby extending the service life. During reverse cleaning, the dynamic position enables the pulse recoil airflow to fully cover the surface of the filter element, remove dust more thoroughly, prevent blockage, and maintain air permeability. The elastic synchronous belt and reverse torsion spring relieve rigid impact and reduce wear. The microcontroller dynamically adjusts the drive parameters in combination with the encoder monitoring data to ensure stable operation of the system. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] A gear cylinder 25 is rotatably sleeved on the rotating frame 9, and the active ring gear 10 is fixedly mounted on the gear cylinder 25. The output shaft ends of the two motors 5 are both connected to the first transmission toothed belts, and the two first transmission toothed belts are respectively connected to the gear cylinder 25 and the rotating frame 9. A pulse back-clearing connector 52 is installed on the spacer 4, and the tail end of the pulse back-clearing connector 52 is connected to the back-clearing chamber 7.

[0044] An inspection cover is provided on the air conditioner body 1 and below the corresponding air inlet;

[0045] When in use, a back-cleaning air pump can be arranged in the air conditioner body 1, and a filter is provided at the air inlet port of the back-cleaning air pump, and the filter is connected to the pulse back-cleaning connector 52. When it is necessary to back-flush the primary filter plate 13 and the filter element 17, the back-cleaning air pump discharges high-pressure air, thereby back-flushing the primary filter plate 13 and the filter element 17;

[0046] This process can effectively remove dust and other impurities accumulated on the primary filter plate 13 and the filter element 17, ensuring their filtering effect and service life, solving the problem of difficult to effectively clean the filter components in the prior art, and improving the overall performance and stability of the air conditioner;

[0047] Four air guide systems are installed on the rotating frame 9. The top of the partition 4 is provided with an air collecting tube 11 which is synchronously linked with the rotating frame 9. The air induction cavity 6 is connected with the inner cavity of the air collecting tube 11. Four air inlet covers 12 are installed on the air collecting tube 11.

[0048] A synchronous shaft 26 is rotatably mounted on the bracket 3. An inner gear ring 28 is mounted on both the rotating frame 9 and the air collecting tube 11.

[0049] The four primary filter plates 13 are respectively a coarse filter plate, a fruit carbon filter plate, a photocatalyst primary filter plate 13 and an electrostatic adsorption filter plate;

[0050] The filtration pore size of the coarse filter plate is 10 μm;

[0051] The fruit carbon filter plate is made of fruit shell carbon;

[0052] The size of the air inlet of each air inlet cover 12 is adapted to the specifications of the electric blinds 2. When in operation, one of the four air inlet covers 12 is in communication with the electric blinds 2.

[0053] Four primary filter plates 13 with different functions perform preliminary filtration on the air entering the air conditioner. The coarse filter plate has a filtration pore size of 10 μm, which can first intercept larger particles of dust and other impurities;

[0054] The fruit carbon filter plate is made of fruit shell carbon, which can effectively absorb odors and some harmful gases in the air;

[0056] The electrostatic adsorption filter plate can absorb tiny particles in the air. This multi-stage preliminary filtration method can more comprehensively purify the air entering the air conditioner. Compared with the single preliminary filtration method of existing technology, it can better improve the cleanliness of the air and reduce the burden of subsequent fine filtration.

[0057] The primary filter plate 13 and the air inlet cover 12 are connected by a snap-fit ​​connection, which facilitates the quick removal or replacement of the primary filter plate 13 from the air inlet cover 12.

[0058] A main ventilation station is provided on the bracket 3, and a central shaft 14 driven by an active gear ring 10 is rotatably mounted on the bracket 3 and corresponding to the position of the main ventilation station;

[0059] The air guide system includes a double-moving component mounted on the rotating frame 9 and driven by the central shaft 14. The double-moving component is driven by a double-moving frame 16 that can move synchronously up and down and back and forth, and a magnetic rotating cylinder 15 that can rotate alternately forward and reverse.

[0060] The reciprocating frequency and moving stroke of the double moving frame 16 change periodically;

[0061] The magnetic rotary drum 15 is rotatably mounted on the double moving frame 16, and a filter element 17 is magnetically attracted inside the magnetic rotary drum 15;

[0062] The magnetic drum 15 is a hollow cylindrical structure with two ends open. The magnetic drum 15 has a permanent magnet built in it. The filter element 17 is provided with an iron top cover, and a handle is installed on the top cover.

[0063] The filtering functions of the four filter elements 17 and the four primary filter plates 13 are all different;

[0064] The four filter elements 17 are respectively a fine filter element, a carbon media element, a UV sterilization element and an odor decomposition element. The odor decomposition element is an activated carbon fiber cotton loaded with nano-TiO2.

[0065] The filtration pore size of the fine filter cartridge is 0.5μm, and the carbon cartridge is coal-based activated carbon;

[0066] The double-moving components include a single moving frame 30, a drive shaft 32 rotatably connected to the rotating frame 9, a differential shaft 33 and a vertical screw 34. The drive shaft 32 is mounted with an external gear 43 adapted to be connected to the intermediate gear 29. A second transmission toothed belt is connected between the differential shaft 33 and the vertical screw 34.

[0067] The single-moving frame 30 is slidably connected to the rotating frame 9, and the vertical screw 34 is transmission-connected to the single-moving frame 30. A large rotary sleeve 35 driven by a drive shaft 32 and a small rotary sleeve 36 linked to a differential shaft 33 are rotatably mounted on the single-moving frame 30.

[0068] A first shaft groove is fixedly formed inside the large rotary sleeve 35 and is open at both ends and is slidably connected to the drive shaft 32. A second shaft groove is fixedly formed inside the small rotary sleeve 36 and is open at both ends and is slidably connected to the differential shaft 33. The cross-sections of the first shaft groove, the second shaft groove, the differential shaft 33, and the drive shaft 32 are all regular polygons.

[0069] Three arc gear rings 37 are mounted on the large rotary sleeve 35. The three arc gear rings 37 have different heights in the axial direction of the large rotary sleeve 35. The radii of the three arc gear rings 37 are different, and the center angles corresponding to the tooth meshing sections of the three arc gear rings 37 are the same, which is 80°. A toothless area is provided between each pair of the arc gear rings 37 on the large rotary sleeve 35, and the center angles corresponding to the three toothless areas are all 40°.

[0070] Three differential gears 38 are mounted on the small rotating sleeve 36, and the three differential gears 38 are respectively meshed with the three arc gear rings 37;

[0071] The radius ratio of the three arc gear rings 37 is 2:3:5, and the gear ratio is consistent with the radius ratio. The radius ratio of the three differential gears 38 is 1:1:1, and the gear ratio is 2:3:5.

[0072] In a preferred technical solution, the number of teeth of the three arc gear rings 37 is 60, 90 and 150 respectively, and the number of teeth of the corresponding three differential gears 38 is 20, 30 and 50 respectively;

[0073] The differential gear 38 has the same module as the arc gear ring 37;

[0074] The teeth of each arc gear ring 37 and each differential gear 38 are coated with a rubber buffer coating to reduce rigid collision and noise between gears;

[0075] The thickness of the rubber buffer coating is 2mm;

[0076] A horizontal screw 39 driven by a small rotary sleeve 36 is rotatably mounted on the single-moving frame 30. The horizontal screw 39 is in transmission connection with the double-moving frame 16. A reverse torsion spring 40 is provided at the rotation connection between the horizontal screw 39 and the single-moving frame 30 and at the rotation connection between the vertical screw 34 and the rotating frame 9.

[0077] A circular shaft 41 is rotatably mounted on the single-moving frame 30. Bevel gears are mounted on the circular shaft 41 and the horizontal screw 39. The two bevel gears are orthogonally meshed. An elastic synchronous belt is connected to the small rotary sleeve 36. The circular shaft 41 and the magnetic rotary cylinder 15 are both connected to the elastic synchronous belt. The elastic synchronous belt is made of rubber and can elastically compensate for the displacement of the single-moving frame 30 and the double-moving frame 16. The inner wall of the elastic synchronous belt is covered with transmission lines.

[0078] The tensile strength of the elastic synchronous belt is ≥10MPa;

[0079] The double-moving frame 16 realizes synchronous up and down and forward and backward reciprocating movement, and the movement frequency and stroke change periodically. The principle is that the middle shaft 14 is driven by the active ring gear 10, and the power is transmitted to the external gear 43 on the drive shaft 32 through the intermediate gear 29 to rotate the drive shaft 32. The drive shaft 32 drives the large rotary sleeve 35 to rotate through the first shaft groove. At the same time, the differential shaft 33 and the vertical screw 34 are linked by the second transmission toothed belt. When the vertical screw 34 rotates, it forms a threaded transmission with the single-moving frame 30, so that the single-moving frame 30 slides up and down along the rotating frame 9. To realize the vertical displacement of the double moving frame 16, the three arc gear rings 37 on the large rotary sleeve 35 are meshed with the three differential gears 38 on the small rotary sleeve 36. When the large rotary sleeve 35 rotates, the meshing state of the arc gear ring 37 and the differential gear 38 changes periodically. The small rotary sleeve 36 drives the horizontal screw 39 to rotate through the differential gear 38. The horizontal screw 39 and the double moving frame 16 form a threaded transmission to make the double moving frame 16 move horizontally. Due to the different parameters of the differential gear 38, the speed of the small rotary sleeve 36 changes periodically, resulting in the horizontal displacement frequency and the horizontal displacement frequency of the double moving frame 16. The process changes periodically in a cycle, and the reversing torsion spring 40 at the rotation connection between the horizontal screw 39 and the single moving frame 30, and the vertical screw 34 and the rotating frame 9 provides a reset force. The magnetic rotary drum 15 is driven by the elastic synchronous belt and the small rotary sleeve 36, and the elastic synchronous belt elastically compensates for the displacement. The technical effect brought about by this movement is that the magnetic rotary drum 15 and the filter element 17 are driven by the double moving frame 16 to perform a compound movement, so that the airflow is disturbed at multiple angles, the probability of impurities contacting the filter element 17 is increased, and the filtration efficiency is improved. At the same time, the filtration load on the surface of the filter element 17 is evenly distributed, and the service life is extended. During reverse cleaning, the dynamic position makes the pulse recoil airflow fully cover the surface of the filter element 17, removing dust more thoroughly, preventing blockage, and maintaining air permeability. It can also adjust the movement mode through the microcontroller 24 according to the data of the air detection module 23 to adapt to different purification needs, and form dynamic multi-stage filtration with the primary filter plate 13, and the elastic synchronous belt and the reversing torsion spring 40 relieve rigid impact and reduce wear. The microcontroller 24 dynamically adjusts the drive parameters in combination with the encoder monitoring data to ensure stable operation of the system.

[0080] The microcontroller 24 is an STM32F407 series with a built-in PID control algorithm;

[0081] A driven drum 18 is rotatably mounted on the partition drum 4. Two valve holes 19 are provided on the partition drum 4. The two valve holes 19 are respectively connected to the air induction chamber 6 and the anti-cleaning chamber 7. A cylinder shell 22 is installed on the double-moving frame 16. A corrugated conduit 21 adapted to communicate with the valve holes 19 is connected between the cylinder shell 22 and the driven drum 18. A dust removal module is provided between the cylinder shell 22 and the partition drum 4.

[0082] The dust exhaust module includes a dust exhaust pipe 48 connected to the cylinder shell 22, a dust exhaust chamber 44 opened in the partition cylinder 4, a dust discharge hole 45 connected to the dust discharge chamber 44 is opened on the partition cylinder 4, the position of the dust discharge hole 45 corresponds to the position of the main ventilation station, the dust exhaust pipe 48 is connected to the driven drum 18 at the position corresponding to the dust discharge hole 45, and a dust discharge cylinder 46 rotatably connected to the dust discharge chamber 44 is installed at the bottom of the partition cylinder 4. A sealing screw plug 47 is threadedly installed on the dust discharge cylinder 46. The axial position of the dust discharge cylinder 46 is provided with an outlet joint 31 connected to the return air chamber 8, and the outlet joint 31 is connected to the air inlet on the air conditioner body 1;

[0083] The dust exhaust pipe 48 is a rubber hose;

[0084] The dust exhaust module can effectively discharge the dust accumulated during the filtration process. After the air is filtered by the filter element 17, dust and other impurities will adhere to the filter element 17. During backflushing cleaning, the dust will be blown into the cylinder shell 22, enter the dust exhaust chamber 44 through the dust exhaust pipe 48, and then enter the dust discharge barrel 46 through the dust discharge hole 45. The sealing screw plug 47 on the dust discharge barrel 46 can be opened regularly to clean the dust. At the same time, the air outlet joint 31 of the dust discharge barrel 46 is connected to the return air chamber 8, which can make part of the air flow back to the air inlet of the air conditioner, realizing the recycling of air. This dust exhaust method solves the problem of dust accumulation affecting the performance of the air conditioner in the prior art, ensures the cleanliness of the interior of the air conditioner, and extends the service life of the air conditioner.

[0085] The return air chamber 8 is provided with a sequence adjustment system for adjusting the state and order of the air flow from the air inlet through the four filter elements 17;

[0086] The sequencing system includes a return air fan 51 installed in the return air chamber 8, a support column 20 is rotatably installed at the bottom of the cylinder shell 22, the support column 20 is adapted to be connected to the filter element 17, a clean air exhaust duct connected to the inner cavity of the filter element 17 is fixedly opened inside the support column 20, the bottom end of the clean air exhaust duct is rotatably connected to a soft conduit 50, the other end of the soft conduit 50 is connected to the return air chamber 8, a return air hose 49 is connected between the driven drum 18 and each corrugated conduit 21, the return air hose 49 is connected to the return air chamber 8, a solenoid valve 42 is installed in each return air hose 49, a one-way air inlet valve is provided at the connection between each corrugated conduit 21 and the driven drum 18, a one-way air outlet valve is installed in each soft conduit 50, and the data end of each solenoid valve 42 is data-connected to the microcontroller 24;

[0087] The sequencing system can adjust the state and order of the airflow through the four filter elements 17 at the air inlet according to actual needs. When the return air fan 51 is working, the air passes through the filter element 17 into the clean air exhaust duct, and then enters the return air chamber 8 through the soft duct 50. The solenoid valve 42 in the return air chamber 8 can control the on and off of each return air hose 49 according to the instructions of the microcontroller 24, thereby adjusting the state and order of the airflow. A one-way air inlet valve is provided at the connection between each corrugated duct 21 and the driven drum 18, and a one-way air outlet valve is provided in the soft duct 50 to ensure the one-way flow of the airflow. This adjustment method can flexibly adjust the filtering order and method according to different air quality and usage scenarios. Compared with the fixed filtering mode of the existing technology, it can more accurately meet the user's requirements for air quality and improve the intelligence and applicability of the air conditioner.

[0088] When this control structure is used, it can adopt a single-function single-stage filtration mode. In the single-function single-stage filtration mode, the airflow flows through the designated filter element 17 once, thereby achieving a single filtration treatment of the air intake flow. In the multi-stage multi-function filtration mode, the airflow can be set in a set direction to flow through multiple filter elements 17 in a set order, and the air intake flow is subjected to multi-stage and multi-function treatment, so that the air intake flow ultimately achieves the set effect, thereby effectively improving the functionality of the device.

[0089] During mode adjustment, the rotating frame 9 changes the set angle under the action of the microcontroller 24, thereby assisting in the adjustment of the mode;

[0090] An air detection module 23 and a microcontroller 24 are provided on the top of the air conditioner body 1 . The microcontroller 24 adjusts the rotation angle of the rotating frame 9 according to the detection result of the air detection module 23 .

[0091] The air detection module 23 includes a PM2.5 sensor, a gas sensor, and a temperature and humidity sensor. The microcontroller 24 is connected to the data end of the air detection module 23. Encoders are integrated in both motors 5. The data ends of the encoders, PM2.5 sensors, gas sensors, and temperature and humidity sensors are all data-connected to the microcontroller 24.

[0092] The air detection module 23 and microcontroller 24 serve as the "intelligent center" of the air conditioning vent control structure. First, the PM2.5 sensor, gas sensor, and temperature and humidity sensor monitor air parameters in real time with a cycle of 100ms, and transmit the data to the microcontroller 24 via the bus. The microcontroller 24 has a built-in multi-level air quality standard database, which compares the real-time data with the preset threshold. When the PM2.5 is less than 35μg / m³ and the gas concentration is less than the first threshold, it is judged as "excellent" and the single-function filtering mode is activated.

[0093] When PM2.5 is greater than or equal to 75μg / m³ or the gas concentration is greater than the second threshold, it is judged as "polluted" and the multi-stage multi-function filtration mode is activated. At the same time, the strategy is adjusted based on temperature and humidity data. When the humidity is greater than 70%RH, the UV sterilization time is increased. The filtration efficiency is calculated based on the position data of the rotating frame 9 fed back by the encoder of the motor 5;

[0094] After the decision is made, the microcontroller 24 drives the motor 5 through the PWM signal to control the rotation angle of the rotating frame 9 so that the corresponding air inlet cover 12 is aligned with the electric blind 2. Each air inlet cover 12 is provided with a unique characteristic code;

[0095] In single-function mode, the air inlet hood 12 is fixed at a fixed angle. In multi-stage multi-function filtering mode, multiple air inlet hoods 12 are switched in a preset order. At the same time, the movement parameters of the double-moving frame 16 are adjusted according to the degree of pollution. The magnetic rotating cylinder 15 rotates alternately forward and reverse with the small rotating sleeve 36. When the encoder detects that the rotating frame 9 has rotated 50 times or the filter element 17 has been used for more than 4 hours, the anti-cleaning program is triggered.

[0096] The pulse back-cleaning connector 52 releases 0.5 MPa high-pressure airflow to back-blow the filter element 17. The driven drum 18 rotates to align the dust discharge pipe 48 with the dust discharge hole 45 to discharge dust. The air outlet connector 31 returns part of the airflow to the air inlet.

[0097] During the execution process, the encoder of the motor 5 continuously feeds back data, and the microcontroller 24 adjusts the driving current of the motor 5 by comparing it with the preset value. The status of each solenoid valve 42 and the one-way valve is fed back through the Hall sensor. If it is stuck, an alarm is issued and the backup path is switched. The microcontroller 24 also stores historical data through the EEPROM and analyzes the rules to generate a pre-filtration plan;

[0098] Taking daily office scenarios as an example, when PM2.5 is equal to 25μg / m³, it is judged as "excellent". The single moving rack 30 is activated at low speed, and only the coarse filter plate is working, reducing energy consumption by 30%. When PM2.5 is equal to 120μg / m³, the multi-filtration mode is triggered. The rotating rack 9 cyclically switches the filter element 17, and the double moving rack 16 reciprocates at a high frequency, backflushing once every 30 minutes to ensure that the air permeability of the filter element 17 is greater than or equal to 85%.

[0099] Its key technical parameters include data acquisition frequency of 10 times / second, decision response time less than or equal to 50ms, positioning accuracy of turntable 9 ±0.5°, recoil pressure of 0.5MPa, and life of solenoid valve 42 greater than or equal to 100,000 opening and closing times, thus realizing closed-loop control of "environmental perception, intelligent decision-making, precise execution, and dynamic optimization."

[0100] PM2.5 sensors need to be calibrated using a standard dust source every 6 months;

[0101] The working principle and use process of the present invention:

[0102] The PM2.5 sensor, gas sensor and temperature and humidity sensor in the air detection module 23 monitor the air parameters in real time with a cycle of 100ms. After the data is transmitted to the microcontroller 24, the microcontroller 24 compares it with the preset threshold of the built-in multi-level air quality standard database to determine the air quality level. When it is judged to be "excellent", the single-time single-function filtering mode is enabled. When it is judged to be "polluted", the multi-level filtering mode is activated. At the same time, the strategy is adjusted in combination with the temperature and humidity data. After the decision is made, the microcontroller 24 drives the motor 5 through the PWM signal to control the rotation angle of the rotating frame 9 so that the corresponding air inlet hood 12 is aligned with the electric blinds 2. In the single-function mode, the specified air inlet hood 12 is at a fixed angle. In the multi-level filtering mode, multiple air inlet hoods 12 are switched in a preset order. After the airflow is initially filtered by the primary filter plate 13 in the air inlet hood 12, it enters the air induced cavity 6 and drives the double moving frame 16 synchronously up and down and front and back through the double-moving components of the air guide system. The reciprocating movement and alternating forward and reverse rotation of the magnetic drum 15 drive the filter element 17 to perform fine filtration. The return air fan 51 and solenoid valve 42 in the sequencing system adjust the state and order of the airflow through the four filter elements 17 according to the instructions of the microcontroller 24 to achieve single or multi-stage filtration. During the filtration process, the dust exhaust module back-blows the filter element 17 when the back-cleaning program is triggered (such as the encoder detects that the rotary rack 9 rotates 50 times or the filter element 17 has been used for more than 4 hours, the pulse back-cleaning connector 52 releases 0.5MPa high-pressure airflow), and the driven drum 18 rotates to align the dust exhaust pipe 48 with the dust discharge hole 45 to discharge dust, and the air outlet connector 31 returns part of the airflow to the air inlet. During the execution process, the encoder of the motor 5 continuously feeds back data, and the microcontroller 24 adjusts the driving current of the motor 5 by comparing with the preset value. The status of each solenoid valve 42 and the one-way valve is fed back through the Hall sensor to ensure the closed-loop control of the system's "environmental perception, intelligent decision-making, precise execution, and dynamic optimization".
