Automated Safety Protection: Through ingenious mechanical linkage, when the shielding arc plate is deployed, the shielding mechanism can automatically raise the protective net to form a physical isolation barrier, effectively preventing children's fingers or pet hair from getting caught in the high-speed rotating parts, greatly improving the safety of the equipment during operation.

[0067] IV. Self-maintenance function of the protective net: After the protective net is fully deployed, the retraction component can drive it to continuously perform high-frequency micro-vibration. This design can automatically shake off the dust attached to the protective net, maintain its breathability, prevent the protective net itself from becoming a new blockage point, and ensure long-term protection and ventilation effects.

[0068] V. Compact structure and high degree of automation: The entire device highly integrates air volume regulation, safety protection and self-cleaning functions. Driven by a single motor and with precise control logic, it realizes the automated operation of complex functions, with a compact structure and excellent user experience. Attached Figure Description

Detailed Implementation

[0082] 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.

[0083] In the embodiments of this invention, please refer to Figures 1 to 12 An air purifier filtration device includes a base plate 1 and a purifier cylinder 2 connected thereto. The purifier cylinder 2 is located on top of the base plate 1. A controller 3 is provided on the outer wall of the purifier cylinder 2. Several sets of air inlets 4 are opened on the bottom circumferential surface of the purifier cylinder 2, and several sets of air outlets 5 are opened on the top circumferential surface. Inside the purifier cylinder 2, a fan 9, a pre-filter 10, a HEPA filter 11, and an activated carbon filter 12 are detachably installed sequentially from bottom to top. The device also includes:

[0084] The air intake volume adjustment mechanism 6 is connected to the base plate 1 at one end and to the purifier cylinder 2 at the other end, and is used to adjust the air intake volume.

[0085] The shielding mechanism 7 is connected to the base plate 1 at one end and to the air intake adjustment mechanism 6 at the other end, and is used to shield the air intake adjustment mechanism 6 in the unfolded state.

[0086] The air intake volume regulating mechanism 6 includes:

[0087] The fixed ring plate 61 is connected to the bottom of the purifier cylinder 2;

[0088] Rotate the ring frame 62 to rotatably connect it with the fixed ring plate 61;

[0089] Motor 63 is connected to fixed ring plate 61;

[0090] The shielding arc plate 64 is rotatably connected to the rotating ring frame 62. The shielding arc plate 64 is provided in several groups and is arranged in a circle with equal spacing, for shielding part of the air inlet 4.

[0091] The power component 65 is connected to the motor 63 at one end and to the shielding arc plate 64 at the other end, and is used to drive the shielding arc plate 64 to rotate and revolve.

[0092] The sequencer 66 is connected at one end to the shielding arc plate 64 and at the other end to the power assembly 65, and is used to limit the rotation sequence of the shielding arc plate 64.

[0093] When the air purifier filtration device of the present invention is working, the controller 3 first starts the fan 9, allowing air to enter the purifier cylinder 2 through the air inlet 4. The pre-filter 10 physically intercepts larger particles, such as hair, pet dander, and large dust particles. The HEPA filter 11 efficiently intercepts micron- and submicron-sized solid particles, such as PM2.5 (particles with a diameter ≤ 2.5 microns), allergens (such as pollen, dust mites, and mold spores), bacteria, some viral aerosols, smoke, and dust. The activated carbon filter 12... Physical and chemical adsorption are used to remove gaseous pollutants and odors, such as formaldehyde, TVOC (total volatile organic compounds) and other indoor air pollution gases, secondhand smoke, kitchen fumes, pet odors and odors from household waste. The purified air flows out from the air outlet 5 and returns to the outside. When the air intake needs to be adjusted, with the cooperation of the sequencing component 66, the power component 65 first drives the shielding arc plate 64 to rotate. When the shielding arc plate 64 rotates to a certain angle, it can no longer rotate. At this time, the power component 65 drives the shielding arc plate 64 to revolve around the central axis of the rotating ring frame 62, which generates vortices at the air intake 4, improving the air intake efficiency. The shielding mechanism 7 shields the deployed shielding arc plate 64.

[0094] As one embodiment of the present invention, please refer to Figure 2 , Figure 5 and Figure 6 The power assembly 65 includes:

[0095] Gear 651 is connected to the output terminal of motor 63;

[0096] The internal gear ring 652 meshes with the gear 651 and is rotatably connected to the fixed ring plate 61;

[0097] The outer toothed ring 653 is connected to the inner toothed ring 652;

[0098] Gear 2 654 meshes with external gear ring 653 and is connected to shielding arc plate 64.

[0099] Motor 63 drives gear 651 to rotate, gear 651 drives internal gear ring 652 to rotate, internal gear ring 652 drives external gear ring 653 to rotate synchronously, and external gear ring 653 drives gear 654 to rotate.

[0100] As one embodiment of the present invention, please refer to Figures 2 to 7 The sequencing component 66 includes:

[0101] Electromagnetic ring 661 is connected to base plate 1;

[0102] A folding cylinder 662 is connected to a rotating ring frame 62. Several sets of folding cylinders 662 are provided and are arranged in a circumferential manner at equal intervals.

[0103] Sliding rod 663 is slidably connected to folding cylinder 662;

[0104] Spring 664, its bottom end is connected to the top end of sliding rod 663, and its top end is connected to folding cylinder 662;

[0105] Magnet 665 is connected to the bottom end of sliding rod 663;

[0106] The power control component 666 is connected at one end to gear 654 and at the other end to rotating ring frame 62;

[0107] The power-on control component 666 includes:

[0108] Folding rod 6661 is connected to gear 654;

[0109] Sliding rod 6662 passes through rotating ring frame 62 and is slidably connected to it;

[0110] A sensor 6663 is connected to a sliding rod 6662, and the sensor 6663 is located outside the rotating ring frame 62.

[0111] Spring 2 6664, one end is connected to the rotating ring frame 62, and the other end is connected to the sensing element 1 6663;

[0112] Folding rod 2, 6666, is connected at one end to rotating ring frame 62;

[0113] The second sensor 6665 is connected to the other end of the second lever 6666 and is on the same straight line as the second sliding lever 6662.

[0114] In the initial state, the shielding arc plate 64 abuts against the outer wall of the purifier cylinder 2, blocking part of the air inlet 4. The first sensor 6663 and the second sensor 6665 are in a separated state. The electromagnetic ring 661 is in an energized state and has magnetism, and is magnetically attracted to the magnet 665. The first spring 664 is in a stretched state. The first folding rod 6661 and the second sliding rod 6662 are in a separated state.

[0115] When gear 2 654 rotates, the magnet 665 and electromagnetic ring 661 are in a state of magnetic attraction, creating resistance. At this time, the rotating ring frame 62 cannot rotate. Gear 2 654 first drives the blocking arc plate 64 to rotate. Simultaneously, gear 2 654 drives the bending rod 1 6661 to rotate. During the rotation of bending rod 1 6661, it abuts against sliding rod 2 6662, compressing sliding rod 2 6662. Sliding rod 2 6662 drives sensing element 1 6663 to move towards the side closer to sensing element 2 6665. Spring 2 6664 undergoes tensile deformation. When sensing element 1 6663 moves to abut against sensing element 2 6665, gear 2 654 can no longer rotate. The blocking arc plate 64 rotates to the specified angle, and controller 3 controls the electromagnetic ring 661 to de-energize. The magnetic attraction disappears, and the spring 1 664... Under the action of force, magnet 665 and sliding rod 663 move upward, motor 63 continues to rotate. Due to the limiting effect of bending rod 6661, gear 654 cannot continue to rotate. At this time, the external gear ring 653 drives gear 654 and rotating ring frame 62 to revolve around the central axis of the purifier cylinder 2. The rotating ring frame 62 drives the shielding arc plate 64 to revolve. The rotating shielding arc plate 64 will "stir" the surrounding air, forming a low-pressure area or induced airflow in the local air inlet 4, similar to a small stirring paddle, actively "pulling" the air towards the air inlet 4, improving the air intake efficiency. At the same time, the rotating shielding arc plate 64 can effectively prevent light pollutants such as dust and hair from clogging the air inlet 4. When rotating, centrifugal force can throw off the dust attached to the shielding arc plate 64, playing a certain self-cleaning role.

[0116] When not in use, motor 63 stops working. At this time, under the reaction force of spring 6664, sliding rod 6662 moves in the opposite direction, driving folding rod 6661 to rotate and sensor 6663 to move. Folding rod 6661 drives gear 654 to rotate in the opposite direction, so that the magnetic shielding plate 64 blocks part of the air inlet 4. Sensor 6663 moves until it separates from sensor 6665. Electromagnetic ring 661 is re-energized to generate magnetic force, which overcomes the resistance of spring 664, so that magnet 665 is re-attracted to electromagnetic ring 661.

[0117] As one embodiment of the present invention, please refer to Figures 1 to 3 , Figures 9 to 12 The blocking mechanism 7 includes:

[0118] The fixed ring frame 71 is connected to the base plate 1;

[0119] Telescopic cylinder 72 is located inside and connected to the fixed ring frame 71. Several sets of telescopic cylinder 72 are provided and are arranged in a circumferential manner at equal intervals.

[0120] The rotating ring plate 73 is connected to the top of the telescopic cylinder 72, and the rotating ring plate 73 abuts against the top of the fixed ring frame 71.

[0121] The shielding net 74 is housed inside the fixed ring frame 71, with its bottom end connected to the fixed ring frame 71 and its top end connected to the rotating ring plate 73. The shielding net 74 is provided in several groups and is arranged in a circumferential pattern with equal spacing.

[0122] The retractable component 75 is connected at one end to the rotating ring frame 62 and at the other end to the telescopic cylinder 72.

[0123] In the initial state, the shielding net 74 is stored inside the fixed ring frame 71; when the shielding arc plate 64 is unfolded, the unfolding component 75 works, causing the telescopic cylinder 72 to extend upward, causing the rotating ring plate 73 to move upward, and the rotating ring plate 73 causes the shielding net 74 to unfold, forming a protective cover to shield the shielding arc plate 64 and ensure the safety of the shielding arc plate 64 during operation.

[0124] As one embodiment of the present invention, please refer to Figure 2 , Figure 3 , Figures 9 to 12 The retraction component 75 includes:

[0125] Connecting cylinder 751 is connected to base plate 1. Several sets of connecting cylinder 751 are provided and are arranged in a circumferential manner with equal spacing.

[0126] Piston 752 moves and abuts against the inner wall of connecting cylinder 751;

[0127] The connecting rod 753 is connected at its bottom end to the piston 752 and is slidably connected to the connecting cylinder 751;

[0128] The reciprocating assembly 754 is connected at one end to the rotating ring frame 62 and at the other end to the connecting rod 753;

[0129] The air intake pipe 755 is connected to the interior of the connecting cylinder 751;

[0130] The air outlet pipe 756 has one end connected to the inside of the connecting tube 751 and the other end connected to the inside of the telescopic tube 72.

[0131] The second air outlet pipe 757 has one end connected to the inside of the connecting cylinder 751;

[0132] The sealing component 758 is connected at one end to the connecting cylinder 751 and at the other end to the other end of the vent pipe 757;

[0133] The air inlet pipe 755 is equipped with a one-way valve to ensure that outside air can only enter the interior of the connecting cylinder 751 in one direction from the air inlet pipe 755. The air outlet pipe 757 is equipped with a one-way valve to ensure that the gas in the connecting cylinder 751 can only flow to the outside from the air outlet pipe 757 in one direction.

[0134] The reciprocating component 754 includes:

[0135] The connecting ring plate 7541 is connected to the top end of the connecting rod 753;

[0136] Triangular blocks 7542 are connected to connecting ring plates 7541. Several groups of triangular blocks 7542 are provided and are arranged in a circle with equal spacing.

[0137] The extrusion rod 7543 is connected to the rotating ring frame 62. Several sets of the extrusion rod 7543 are provided and are arranged in a circumferential manner at equal intervals.

[0138] Spring 7544 is connected to piston 752 at its top end and to connecting cylinder 751 at its bottom end;

[0139] The blocking assembly 758 includes:

[0140] The telescopic damper 7581 is connected at one end to the connecting cylinder 751;

[0141] The sealing plate 7582 is connected to the other end of the telescopic damper 7581 and abuts against the second air outlet pipe 757.

[0142] Spring 4 7583 is connected at one end to connecting cylinder 751 and at the other end to sealing plate 7582.

[0143] In the initial state, the sealing plate 7582 seals the second vent pipe 757;

[0144] When the rotating ring frame 62 and the blocking arc plate 64 revolve, the rotating ring frame 62 drives the extrusion rod 7543 to revolve. During the revolve, the extrusion rod 7543 abuts against the triangular block 7542 and extrudes it, causing the triangular block 7542 to extrude the connecting ring plate 7541, and then extrudes the connecting rod 753 and the piston 752, causing the piston 752 to move downward. The spring 7544 undergoes compression deformation. During the downward movement of the piston 752, the air in the connecting cylinder 751 is forced into the telescopic cylinder 72 through the air outlet pipe 756, causing the telescopic cylinder 72 to extend upward. When the extrusion rod 7543 disengages from the triangular block 7542, under the reaction force of the spring 7544, the piston 752 moves upward, drawing outside air into the connecting cylinder 751 through the air inlet pipe 755.

[0145] The above process is repeated continuously, allowing outside air to continuously enter the telescopic cylinder 72. When the telescopic cylinder 72 extends to its maximum distance, the shielding net 74 is fully deployed to form a protective cover, which shields the shielding arc plate 64.

[0146] At this time, piston 752 continues to reciprocate under the action of spring 7544 and compression rod 7543, and outside air continues to enter the connecting cylinder 751. At this time, the air pressure inside the connecting cylinder 751 increases, forcing open the sealing plate 7582 and flowing out from the outlet pipe 757. During this process, due to the damping effect of telescopic damper 7581, the closing of sealing plate 7582 is delayed. When piston 752 moves upward, some air in telescopic cylinder 72 and some outside air are drawn into connecting cylinder 751. As some of the gas inside the telescopic cylinder 72 is lost, the telescopic cylinder 72 retracts downward a certain distance under the action of the connecting ring plate 7541 and gravity. When the piston 752 moves upward, it forces some of the gas inside the connecting cylinder 751 into the second air outlet pipe 757, and forces some of the gas back into the telescopic cylinder 72, causing the telescopic cylinder 72 to move upward. This causes the connecting ring plate 7541 to continuously vibrate longitudinally, which in turn causes the shielding net 74 to vibrate, shaking off the dust adhering to the shielding net 74 and ensuring its air permeability.

[0147] As one embodiment of the present invention, please refer to Figure 1 and Figure 2 It also includes:

[0148] Folding plate 8 is connected to rotating ring frame 62.

[0149] The folding plate 8 is used to cover the unfolding component 75, ensuring the overall aesthetics of the device.

[0150] The working principle of this invention is as follows: In the initial state, the sealing plate 7582 blocks the second air outlet pipe 757, the shielding net 74 is stored inside the fixed ring frame 71, the shielding arc plate 64 abuts against the outer wall of the purifier cylinder 2, and partially blocks the air inlet 4. The first sensor 6663 and the second sensor 6665 are in a separated state, the electromagnetic ring 661 is in an energized state and has magnetism, and is magnetically attracted together with the magnet 665. The first spring 664 is in a stretched state, and the first folding rod 6661 and the second sliding rod 6662 are in a separated state.

[0151] During operation, the fan 9 is first activated via the controller 3, allowing air to enter the purifier cylinder 2 through the air inlet 4. The pre-filter 10 physically intercepts larger particles, such as hair, pet dander, and large dust particles. The HEPA filter 11 efficiently intercepts micron-sized and submicron-sized solid particles, such as PM2.5 (particles with a diameter ≤ 2.5 microns), allergens (such as pollen, dust mites, and mold spores), bacteria, some viral aerosols, smoke, and dust. The activated carbon filter 12 physically and chemically adsorbs gaseous pollutants and odors, such as formaldehyde, TVOC (total volatile organic compounds), and other indoor air pollution gases, secondhand smoke, kitchen fumes, pet odors, and odors from household waste. The purified air flows out through the air outlet 5 and returns to the outside environment.

[0152] When an increase in air intake is required, motor 63 drives gear 1 651 to rotate, gear 1 651 drives internal gear ring 652 to rotate, internal gear ring 652 drives external gear ring 653 to rotate synchronously, and external gear ring 653 drives gear 2 654 to rotate. When gear 2 654 rotates, due to the magnetic attraction between magnet 665 and electromagnetic ring 661, there is resistance. At this time, rotating ring frame 62 cannot rotate. Gear 2 654 first drives the blocking arc plate 64 to rotate. At the same time, gear 2 654 drives the bending rod 1 6661 to rotate. During the rotation of bending rod 1 6661, it abuts against sliding rod 2 6662, squeezing sliding rod 2 6662. Sliding rod 2 6662 drives sensor 1 6663 to move towards sensor 2 6665. Spring 2 6664 is stretched and deformed. When sensor 1 6663 moves to abut against sensor 2 6665, gear 2 654 can no longer rotate. 4. When rotated to the specified angle, the controller 3 controls the electromagnetic ring 661 to de-energize, the magnetic attraction disappears, and under the reaction force of the spring 664, the magnet 665 and the sliding rod 663 move upward, and the motor 63 continues to rotate. Due to the limiting effect of the bending rod 6661, the gear 654 can no longer rotate. At this time, the external gear ring 653 drives the gear 654 and the rotating ring frame 62 to revolve around the central axis of the purifier cylinder 2 in sync. The rotating ring frame 62 drives the shielding arc plate 64 to revolve. The rotating shielding arc plate 64 will "stir" the surrounding air, forming a low-pressure area or induced airflow in the local area of ​​the air inlet 4, similar to a small stirring paddle, actively "pulling" the air towards the air inlet 4 to improve the air intake efficiency. At the same time, the rotating shielding arc plate 64 can effectively prevent dust, hair and other light pollutants from clogging the air inlet 4. When rotating, the centrifugal force can throw off the dust attached to the shielding arc plate 64, which plays a certain self-cleaning role.

[0153] Rotating the ring frame 62 drives the extrusion rod 7543 to revolve. During the revolve, the extrusion rod 7543 abuts against the triangular block 7542 and extrudes it, causing the triangular block 7542 to extrude the connecting ring plate 7541, and then extrudes the connecting rod 753 and the piston 752, causing the piston 752 to move downward. The spring 7544 is compressed and deformed. During the downward movement of the piston 752, the air in the connecting cylinder 751 is forced into the telescopic cylinder 72 through the air outlet pipe 756, causing the telescopic cylinder 72 to extend upward. When the extrusion rod 7543 disengages from the triangular block 7542, the piston 752 moves upward under the reaction force of the spring 7544, drawing outside air into the connecting cylinder 751 through the air inlet pipe 755.

[0154] The above process is repeated continuously, allowing outside air to continuously enter the telescopic cylinder 72. When the telescopic cylinder 72 extends to its maximum distance, the shielding net 74 is fully deployed to form a protective cover, which shields the shielding arc plate 64.

[0155] At this time, piston 752 continues to reciprocate under the action of spring 7544 and compression rod 7543, and outside air continues to enter the connecting cylinder 751. At this time, the air pressure inside the connecting cylinder 751 increases, forcing open the sealing plate 7582 and flowing out from the outlet pipe 757. During this process, due to the damping effect of telescopic damper 7581, the closing of sealing plate 7582 is delayed. When piston 752 moves upward, some air in telescopic cylinder 72 and some outside air are drawn into connecting cylinder 751. As part of the gas is lost from the telescopic cylinder 72, the telescopic cylinder 72 retracts downward a certain distance under the action of the connecting ring plate 7541 and gravity. When the piston 752 moves upward, it forces part of the gas in the connecting cylinder 751 into the second air outlet pipe 757, and forces part of the gas back into the telescopic cylinder 72, causing the telescopic cylinder 72 to move upward. This causes the connecting ring plate 7541 to continuously vibrate longitudinally, which in turn causes the shielding net 74 to vibrate, shaking off the dust adhering to the shielding net 74 and ensuring its air permeability.

[0156] When not in use, motor 63 stops working. At this time, under the reaction force of spring 6664, sliding rod 6662 moves in the opposite direction, driving folding rod 6661 to rotate and sensor 6663 to move. Folding rod 6661 drives gear 654 to rotate in the opposite direction, so that the magnetic shielding plate 64 partially blocks the air inlet 4. Sensor 6663 moves until it separates from sensor 6665. Electromagnetic ring 661 is re-energized to generate magnetic force, which overcomes the resistance of spring 664, so that magnet 665 is re-attracted to electromagnetic ring 661. Gas in telescopic cylinder 72 flows out through air outlet pipe 757, so that shielding net 74 is re-stored inside fixed ring frame 71.
