[0023] 3. The present invention uses a wind direction monitoring switching mechanism to coordinate the use of mechanical negative pressure suction and wind force switching, and can greatly reduce energy consumption, which will also greatly reduce the cost of air treatment and avoid using mechanical energy to suck the air for a long time during air treatment. After all, improving energy efficiency increases costs, increases wear on the mechanical end, and reduces the service life of the suction end. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] See also Figure 1-8 , the present invention provides a technical solution: an environmentally friendly air purification device for building decoration, comprising a fixing frame 1, the fixing frame 1 is a hexagonal structure in side view;

[0037] The stepping switching mechanism 3 includes a rotating tooth groove 304, and a plurality of rotating tooth grooves 304 are equidistantly arranged around the left side of the mounting circular frame 402;

[0038] The processing end monitoring mechanism 5 further includes a monitoring frame head 501 and contact notches 505. The four contact notches 505 are provided in the middle of one side opposite to the filter cartridge 401 on the four sides. The four monitoring frame heads 501 are respectively installed in the middle of one side opposite to the filter cartridge 401 on the four sides by bolts.

Several mounting rings 604 are respectively installed on the two ends of the opposite side of the filter cartridge 401 around by bolts, and several guide wheels 607 are respectively installed on the filter cartridge 401 around by bolts and are located on one side of the mounting ring 604.

[0040] The stepping switching mechanism 3 also includes a stepping motor 301, a rotating gear 302 and a rotating rod 303. The stepping motor 301 is installed at the middle of the top of the inner cavity of the fixed frame 1 by bolts, and the rotating rod 303 is installed at the output end on the left side of the stepping motor 301 by bolts. The rotating gear 302 is installed at the right side of the middle of the rotating rod 303 by bolts. The rotating gear 302 is meshed with the rotating tooth groove 304. The left end of the rotating rod 303 is connected to the upper left end of the inner cavity of the fixed frame 1 by bolts, and an alarm is installed inside the control panel.

[0041] The specific implementation is as follows: when the stepper motor 301 is started, the rotating rod 303 is driven to rotate, and the rotating gear 302 is driven to rotate through the rotating rod 303. Since the rotating gear 302 and the rotating tooth groove 304 are meshed with each other, the mounting frame 402 is driven to rotate.

[0042] The wind direction monitoring switching mechanism 2 also includes a sealing sheet 204, a mounting ball 205, a mounting sleeve 206, a fixed spring 207, a movable ball 208, a starting guide ring 209 and a connecting guide block 210. The mounting sleeve 206 is mounted on the upper end of the inner cavity of the fixed bottom frame 202 by bolts, the mounting ball 205 is movably mounted in the middle of the mounting sleeve 206, the bottom end of the movable rod 203 passes through the middle of the mounting ball 205, the movable ball 208 is mounted on the bottom end of the movable rod 203 by bolts, and the sealing sheet 204 is mounted by bolts. Installed in the middle of the top of the fixed bottom frame 202, the connecting guide block 210 is installed in the middle of the bottom end of the inner cavity of the fixed bottom frame 202 by bolts, the bottom end of the movable ball 208 is installed with a conductive layer by bolts, the starting guide ring 209 is installed in the middle and lower end of the inner cavity of the fixed bottom frame 202 by bolts, the starting guide ring 209 and the conductive layer are electrically connected to the alarm, and a plurality of fixed springs 207 are respectively installed around the two sides of the bottom end of the mounting circular sleeve 206 by bolts, and the bottom end of the fixed spring 207 is connected to the bottom end of the movable rod 203 by bolts;

[0043] The specific implementation method is as follows: when performing air filtration, if the external wind force is large, it will contact with the force-bearing plate 201 and push the force-bearing plate 201, causing the force-bearing plate 201 to tilt and drive the movable rod 203 to move, and drive the bottom end of the movable rod 203 to move to the opposite side with the installation ball 205 and the installation sleeve 206 as the axis, and drive the movable ball 208 to move, so that the conductive layer is separated from the upper end of the connection guide block 210, and the circuit of the fan 410 is disconnected, so that the fan 410 stops working, and the external air is blown into the filter cartridge 401 by wind force, and the conductive layer is in contact with the starting guide ring 209, and the alarm is started to tell the worker The staff, now the wind is too strong, the air is filtered by the wind, when the bottom end of the movable rod 203 moves, the fixed spring 207 will be squeezed, and later the movable rod 203 and the force plate 201 will be reset by the fixed spring 207 after squeezing, and the mechanical negative pressure suction method and the switching of wind force are used in conjunction, and the energy consumption can be greatly reduced, and the cost of air treatment can be greatly reduced, avoiding the use of mechanical energy to suck the air for a long time during air treatment. After all, improving energy efficiency increases costs, and it will also increase wear on the mechanical end and reduce the service life of the suction end.

[0044] The middle of the mounting sleeve 206 is a circular structure when viewed from above, the fixed spring 207 is made of spring steel, the sealing sheet 204 is made of rubber, the outer periphery of the movable ball 208 and the inner periphery of the mounting sleeve 206 are polished, the starting guide ring 209 is a circular ring structure when viewed from above, a mounting circular opening is provided in the middle of the top of the fixed bottom frame 202, the fixed bottom frame 202 is a rectangular structure, and the force plate 201 is a cross-shaped structure when viewed from above;

[0045] The specific implementation is as follows: the force-bearing plate 201 with a cross-shaped structure can contact the wind direction in any direction and can push the force-bearing plate 201 to move, and the flexibility of the movable ball 208 when rotating inside the mounting sleeve 206 is increased through polishing.

[0046] The rotating switching mechanism 4 also includes a mounting slide 403, a mounting ring rail 404, a porous solenoid valve tube 405, a filter plate 406, a guide pipe head 407, a transmission round port 408, a connecting round port 409 and a fan 410. The fan 410 is installed in the middle of the left side of the fixed frame 1 by bolts, and the connecting guide block 210 and the conductive layer are electrically connected to the fan 410 respectively. The two mounting ring rails 404 are respectively arranged around the two sides of the mounting circular frame 402, and the two mounting slides 403 are respectively slidably installed inside the mounting ring rails 404 on both sides. The side of the mounting slide 403 away from the mounting ring rail 404 is connected to the outside of the mounting circular frame 402 by bolts, and the outside of the mounting ring rail 404 and the inside of the fixed frame 1 are installed with a bracket by bolts, and the filter plate 406 is bolted. It is installed at the bottom of the middle right side of the fixed frame 1, and the guide pipe head 407 is installed at the bottom of the middle right side of the inner cavity of the fixed frame 1 by bolts. The left side of the guide pipe head 407 contacts and squeezes with the bottom of the middle right side of the mounting frame 402. A number of delivery round ports 408 are respectively opened around the two sides of the mounting frame 402. The middle of both sides of the filter cartridge 401 are provided with connecting round ports 409. The porous solenoid valve tube 405 is installed at the middle of the left side of the mounting frame 402 by bolts. A connecting hose is installed on the left side of the porous solenoid valve tube 405 by bolts, and the end of the connecting hose away from the porous solenoid valve tube 405 is connected to the fan 410 by bolts. The air pipes arranged inside the porous solenoid valve tube 405 are respectively connected to the delivery round ports 408 on the left side of the mounting frame 402 by bolts.

[0047] The specific implementation is as follows: the stepper motor 301 and the porous electromagnetic valve tube 405 are started by the touch switch 504. When the stepper motor 301 is started, the rotating rod 303 is driven to rotate, and the rotating gear 302 is driven to rotate by the rotating rod 303. Since the rotating gear 302 and the rotating tooth groove 304 are meshed with each other, the mounting frame 402 is driven to rotate. When the mounting frame 402 rotates, the mounting slide bar 403 is driven to slide inside the mounting ring rail 404, thereby increasing the stability of the mounting frame 402 during rotation. When the mounting frame 402 rotates, the filter cartridge 401 is driven to rotate, and the unused filter cartridge 401 is rotated to the bottom end of the inner cavity of the fixed frame 1, so that the transmission round port 408 is in contact with and squeezed by the guide pipe head 407, and the porous electromagnetic valve tube 405 is started. 05 is located inside the bottom end of the inner cavity of the fixed frame 1, and the external air is drawn into the switched filter cartridge 401 through the fan 410 for filtering. When performing air filtering, by switching the control filter end, not only the working time of the air filtering process can be increased, but also the stability of the air processing and the efficiency of the air filtering process can be increased, so as to avoid reducing the efficiency and time of the filtering process by using only one filter end during air processing. After a period of use, the filter end needs to be replaced. If the staff forgets to replace it, the forgotten filter end will continue to work, which will not only fail to achieve the filtering effect, but also cause the negative pressure end to continue to work, increasing energy consumption.

[0048] The installation slide bar 403 and the installation ring rail 404 are both circular structures when viewed from the side. The outer periphery of the installation slide bar 403 and the inner periphery of the installation ring rail 404 are polished. A conveying circular groove is provided at the bottom right end of the fixed frame 1 at a position relative to the filter plate 406. An air hole is provided in the middle left end of the fixed frame 1. A fixing pin plate 7 is installed at the top of the fixed frame 1 by bolts. A wet filter body is added inside the filter cartridge 401.

[0049] The specific implementation is as follows: when the fixed frame 1 is installed and fixed, the fixed frame 1 is fixed by the fixing pin plate 7, and the fixing is more convenient. By polishing the outer periphery of the mounting slide bar 403 and the inner periphery of the mounting ring rail 404, the flexibility of the mounting slide bar 403 when sliding inside the mounting ring rail 404 is increased, and the friction during the rotation process is reduced.

[0050] The processing end monitoring mechanism 5 also includes a cutting blade 502, a fixedly connected cotton strip 503, a touch switch 504 and a movable block 506. Several fixedly connected cotton strips 503 are movably arranged inside the monitoring frame head 501. One end of the fixedly connected cotton strip 503 close to the filter cartridge 401 passes through the contact notch 505 to contact the wet filter body. One end of the fixedly connected cotton strip 503 away from the contact notch 505 is installed with a movable block 506 by bolts. Several cutting blades 502 are installed on the movable block 506 and close to one side of the fixedly connected cotton strip 503 by bolts. One end of the left side of the monitoring frame head 501 close to the contact notch 505 is installed with a touch switch 504 by bolts. The touch switch 504 is electrically connected to the stepping motor 301, and the touch switch 504 is electrically connected to the porous electromagnetic valve tube 405.

[0051] The specific implementation is as follows: during the use of the filter cartridge 401, as the filtering time becomes longer, the wet filter body inside the filter cartridge 401 will gradually become dry, and the fixedly connected cotton strip 503 will become dry. When the fixedly connected cotton strip 503 becomes dry, it will shrink and drive the movable block 506 to move toward the side of the contact slot 505. When the movable block 506 moves, it drives the cutting blade 502 to move, so that the cutting blade 502 contacts and squeezes the limiting rope 601, which will cut off the limiting rope 601. When the movable block 506 moves, it will contact the touch switch 504.

[0052] A number of round beads are evenly installed around the outside of the movable block 506. Slide holes are provided at both ends of the monitoring frame head 501 close to the filter cartridge 401. A discharge slot 10 is provided in the middle of the bottom end of the fixed frame 1. A receiving frame 8 is installed at the bottom end of the fixed frame 1 through bolts. Elastic push rods are installed at the relative positions of the filter cartridge 401 around the middle of the mounting frame 402 through bolts. The elastic push rods are in a compressed state, and the ends of the elastic push rods away from the mounting frame 402 are in contact with the filter cartridges 401 around them.

[0053] The specific implementation is as follows: when the movable block 506 moves, it drives the balls around it to roll, thereby increasing the flexibility of the movable block 506 when moving and reducing the friction of the movable block 506 when moving.

[0054] The limiting mechanism 6 also includes a limiting rope 601, a circular stopper 602, a pushing spring 603, a limiting recess 605 and a limiting push rod 606. Several limiting push rods 606 are respectively slidably installed in the installation ring sleeve 604. The limiting push rods 606 on both sides are installed with circular stoppers 602 at opposite ends by bolts. The circular stoppers 602 on both sides are installed with pushing springs 603 on the side close to the installation ring sleeve 604 by bolts. The pushing spring 603 and one end away from the circular stopper 602 are connected to one side of the installation ring sleeve 604 by bolts. The limiting rope 601 is installed on the right side of the circular stopper 602 on the right side by bolts. The limiting rope 601 and one end away from the circular stopper 602 pass through the guide wheels 607 on both sides and are connected to the left side of the circular stopper 602 on the left side. Several limiting recesses 605 are respectively opened on both sides of the inner cavity of the installation round frame 402 at the relative positions of the limiting push rods 606. The limiting rope 601 passes through the interior of the monitoring frame head 501 through the sliding hole.

[0055] The specific implementation is as follows: after the limiting rope 601 is cut off, the limiting push rods 606 on both sides lose their restraining force, and the pushing spring 603 will lose its restraining force, and the pushing spring 603 in a compressed state will drive the limiting push rods 606 on both sides to move to one side of the mounting ring sleeve 604, and the limiting push rods 606 on both sides are separated from the limiting recess 605, and the filter cartridge 401 loses its restraining force, and the elastic push rods in a compressed state push the filter cartridge 401 to move to the side away from the mounting circular frame 402, so that the filter cartridge 401 is separated from the inside of the mounting circular frame 402, and the filter cartridge 401 after use is separated to avoid the used filter end being still on the switching end during the switching process, and the used filter end is easily confused and continued to be used without knowing it in the later stage, which will not only reduce the efficiency of air filtration without knowing it, but also cause energy waste due to adsorption filtration, resulting in reduced stability during use.

[0056] The cross-sections of the limiting push rod 606 and the limiting recess 605 are both rectangular structures. The limiting push rod 606 is movably equipped with round balls around one side away from the circular stopper 602. The front side of the fixed frame 1 is equipped with an observation plate 9 by bolts. The push springs 603 are all in a compressed state.

[0057] The specific implementation is: when the limiting top rod 606 is moving, it drives the ball to roll to increase the flexibility of the limiting top rod 606 when moving, reduce the friction of the limiting top rod 606 when moving, and avoid excessive friction when the limiting top rod 606 moves, resulting in the limiting top rod 606 being unable to separate from the inside of the limiting recess 605 in time.

[0058] Working principle: In the process of using the filter cartridge 401 of the present invention, as the filtering time becomes longer, the wet filter body inside the filter cartridge 401 will gradually become dry, and the fixedly connected cotton strip 503 will become dry. When the fixedly connected cotton strip 503 becomes dry, it will shrink and drive the movable block 506 to move to one side of the contact notch 505. When the movable block 506 moves, it drives the cutting blade 502 to move, so that the cutting blade 502 contacts and squeezes the limiting rope 601, and the limiting rope 601 will be cut off. When the movable block 506 moves, it will contact the touch switch 504. After the limiting rope 601 is cut off, the limiting top rods 606 on both sides lose their restraining force, and the pushing spring 603 loses its restraining force, and the pushing force in the compressed state is released. The spring 603 drives the limiting push rods 606 on both sides to move toward one side of the mounting ring sleeve 604, and separates the limiting push rods 606 on both sides from the limiting recess 605, and makes the filter cartridge 401 lose its restraining force, and pushes the filter cartridge 401 to move away from the mounting round frame 402 through the elastic push rods in a compressed state, so that the filter cartridge 401 is separated from the inside of the mounting round frame 402, and the filter cartridge 401 after use is separated, so as to avoid that the used filter end is still on the switching end during the switching process, and the used filter end is easily confused and continued to be used without knowing it in the later stage, which will not only reduce the efficiency of air filtration, but also cause energy waste due to adsorption filtration, resulting in reduced stability during use;

[0059] The stepper motor 301 and the porous solenoid valve tube 405 are started by the touch switch 504. When the stepper motor 301 is started, the rotating rod 303 is driven to rotate, and the rotating gear 302 is driven to rotate by the rotating rod 303. Since the rotating gear 302 and the rotating tooth groove 304 are meshed with each other, the mounting frame 402 is driven to rotate. When the mounting frame 402 rotates, the mounting slide bar 403 is driven to slide inside the mounting ring rail 404, thereby increasing the stability of the mounting frame 402 when rotating. When the mounting frame 402 rotates, the filter cartridge 401 is driven to rotate, and the unused filter cartridge 401 is rotated to the bottom end of the inner cavity of the fixed frame 1, so that the transmission round port 408 is in contact with and squeezed with the guide pipe head 407, and the porous solenoid valve tube 405 is started. The filter cartridge 401 is located at the bottom end of the inner cavity of the fixed frame 1, and the external air is drawn into the switched filter cartridge 401 through the fan 410 for filtering. When performing air filtering, by switching the control filter end, not only the working time of the air filtering process can be increased, but also the stability of the air processing and the efficiency of the air filtering process can be increased, so as to avoid that when processing the air, only one filter end is used, which will reduce the efficiency and time of the filtering process. After using it for a period of time, the filter end needs to be replaced. If the staff forgets to replace it, the forgotten filter end will continue to work, which will not only fail to achieve the filtering effect, but also cause the negative pressure end to continue to work and increase energy consumption.

[0060] During air filtering, if the external wind force is strong, it will contact with the force-bearing plate 201 and push the force-bearing plate 201, causing the force-bearing plate 201 to tilt and drive the movable rod 203 to move, and drive the bottom end of the movable rod 203 to move to the opposite side with the installation ball 205 and the installation sleeve 206 as the axis, and drive the movable ball 208 to move, so that the conductive layer is separated from the upper end of the connection guide block 210, and the circuit of the fan 410 is disconnected, so that the fan 410 stops working, and the external air is blown into the filter cartridge 401 by wind force, and the conductive layer is in contact with the starting guide ring 209, and the alarm is started to tell the working Personnel, now the wind is too strong and the air is filtered by wind. When the bottom end of the movable rod 203 moves, the fixed spring 207 will be squeezed. Later, the movable rod 203 and the force-bearing plate 201 will be reset after being squeezed. And through the mechanical negative pressure suction method and the switching of wind force, it can greatly reduce the energy consumption, and it will also greatly reduce the cost of air treatment, avoid using mechanical energy to suck the air when treating the air, and use it for a long time. After all, improving energy efficiency increases costs, and it will also increase wear on the mechanical end and reduce the service life of the suction end.
