Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] Reference Figure 1-Figure 14A ventilation duct purification and disinfection device with a wind power generation component includes a device body 1, a plurality of shells 7 are installed inside the device body 1, and fan blades 11 for wind power generation are installed inside the plurality of shells 7. A micro-electrostatic discharge component 8 and a micro-electrostatic filter 10 for air purification and disinfection are installed inside the device body 1 below the plurality of shells 7. A box body 2 is installed on the top of the device body 1, and a ventilation duct body 3 is arranged on the top of the box body 2. The box body 2 and the ventilation duct body 3 are connected and fixed by a connecting mechanism. A filter plate 21 is slidably installed inside the box body 2, and a first cleaning mechanism and a second cleaning mechanism for automatically cleaning both sides of the filter plate 21 are installed inside the box body 2. An adjusting mechanism for adjusting the wind force is installed at one end of the box body 2 close to the ventilation duct body 3.

[0026] As a technical optimization solution of the present invention, a lithium battery 9 for storing excess electric energy is installed inside the device body 1, and a shutter 4 is installed at the bottom end of the device body 1.

[0027] As a technical optimization solution of the present invention, the connection mechanism includes two fixing plates 13, which are respectively arranged inside one end of the box body 2 close to the ventilation duct body 3, and the outer walls of the two fixing plates 13 on the side away from each other are both installed with threaded rotating parts 6, and the end of the ventilation duct body 3 close to the box body 2 is provided with two grooves 5 adapted to the fixing plates 13. After one end of the box body 2 is sleeved on the surface of the ventilation duct body 3, the two fixing plates 13 are driven to move toward each other by rotating the two threaded rotating parts 6 until the two fixing plates 13 are moved to the inside of the grooves 5, and the installation of the box body 2 and the device body 1 can be completed.

[0028] As a technical optimization solution of the present invention, the adjustment mechanism includes a mounting plate 12 arranged inside the box body 2, and two first slide grooves 17 are provided on the inner top surface and the inner bottom surface of the box body 2, and first sliders 24 are installed inside the two first slide grooves 17, and the upper and lower ends of the mounting plate 12 are connected to the first sliders 24 close to them. First linear motors are pre-installed inside the two first slide grooves 17, and the first linear motors can adjust the first sliders 24 to move back and forth inside the first slide grooves 17, thereby driving the mounting plate 12 to move back and forth in the box body 2.

[0029] As a technical optimization solution of the present invention, a plurality of telescopic pipes 14 corresponding to the positions of the shell 7 are installed inside the mounting plate 12 , and the telescopic ends of the plurality of telescopic pipes 14 are commonly connected to a fixing frame 22 .

[0030] As a technical optimization solution of the present invention, a motor 16 is installed on the outer wall of one side of the mounting plate 12 close to the ventilation duct body 3, and the output end of the motor 16 passes through the mounting plate 12 and is connected to a screw rod 19, and the end of the screw rod 19 away from the motor 16 passes through the fixing frame 22 and is connected to a rectangular block 25. While the motor drives the screw rod 19 to rotate, it can drive the fixing frame 22 to move in a direction away from the mounting plate 12, thereby driving the telescopic ends of the multiple telescopic pipes 14 to extend together; because the diameter of the air inlet end of the telescopic pipe 14 is larger than the diameter of the air outlet end, the wind force blowing to the multiple fan blades 11 can be adjusted.

[0031] As a technical optimization solution of the present invention, the first cleaning mechanism includes a second chute 18 opened on the top surface of the box body 2, two second sliders 26 are installed inside the second chute 18, and the bottom ends of the two second sliders 26 are both installed with moving rods 20, and the outer wall of one side of the two moving rods 20 close to the filter plate 21 is installed with a first cleaning brush 28. Two second linear motors are pre-installed inside the second chute 18, which can drive the two second sliders 26 to move in the second chute 18 in a direction of approaching or moving away from each other, and drive the two moving rods 20 and the first cleaning brush 28 to clean the outer wall of one side of the filter plate 21 while moving.

[0032] As a technical optimization scheme of the present invention, rectangular through grooves 27 are provided at both upper and lower ends of the two movable rods 20, and mounting blocks are rotatably installed inside the multiple rectangular through grooves 27, and electric telescopic rods 29 are installed at one end of the multiple mounting blocks away from the rotating part, and cylindrical air bags 30 are installed at the telescopic ends of the multiple electric telescopic rods 29, and multiple openings 31 for rotating the electric telescopic rods 29 are provided inside the filter plate 21. During actual use, the mounting block is connected to the inner walls on both sides of the rectangular through groove 27 via an electric rotating shaft, which can be driven to rotate by an external driving device or other driving methods, thereby driving the mounting block to rotate inside the rectangular through groove 27; and a servo motor is pre-installed inside the mounting block, and the output end of the servo motor is connected to the electric telescopic rod 29, thereby driving the electric telescopic rod 29 to rotate; a wear-resistant fluff layer is bonded to the outer wall of the airbag 30, and when the airbag 30 is in an inflated state, its diameter is adapted to the diameter of the telescopic end of the telescopic pipe 14, so that the wear-resistant fluff layer on the outer wall of the airbag 30 abuts against the inner wall of the telescopic pipe 14.

[0033] As a technical optimization solution of the present invention, the second cleaning mechanism includes a rotating block 32 rotatably mounted in the middle of the filter plate 21, a slot 33 is provided at one end of the rotating block 32 close to the adjustment mechanism, the slot 33 is plugged and adapted with the rectangular block 25, a discharge port for discharging impurities is provided at the bottom of the box body 2, and a sealing plate 15 is rotatably mounted inside the discharge port. The mounting plate 12 is driven to move toward the filter plate 21 by a plurality of first sliders 24, thereby driving the rectangular block 25 set at one end of the screw rod 19 to be plugged into the slot 33, so that the rotation of the screw rod 19 can drive the rotating block 32 to rotate together.

[0034] As a technical optimization solution of the present invention, a cross-shaped mounting frame 23 is installed at the other end of the rotating block 32, and a plurality of third slide grooves are provided on the side of the mounting frame 23 close to the filter plate 21, and a third slider 35 is installed inside the plurality of third slide grooves, and a moving plate 34 is installed on the end of the plurality of third sliders 35 away from the third slide groove, and a second cleaning brush is installed on the side of the mounting frame 23 and the plurality of moving plates 34 close to the filter plate 21. A third linear motor is pre-installed inside the plurality of third slide grooves, which can drive the corresponding third slider 35 to move back and forth in the third slide groove; while the screw rod 19 drives the rotating block 32 to rotate, it can drive the mounting frame 23 and the moving plate 34 to rotate together on the other side of the filter plate 21, and the other side of the filter plate 21 can be cleaned with the help of the plurality of second cleaning brushes, and during the cleaning process, the plurality of third sliders 35 drive the moving plate 34 to extend and retract in the third slide groove to avoid the generation of cleaning dead corners.

[0035] In the present invention, when the user uses the device, the box body 2 is mounted on the air outlet of the ventilation duct body 3, so that the position of the fixing plate 13 inside the box body 2 corresponds to the position of the groove 5, and the two fixing plates 13 are driven to move toward each other by rotating the two threaded rotating parts 6 until both fixing plates 13 are moved to the inside of the groove 5, and the installation of the box body 2 and the device body 1 is completed.

[0036] The air discharged from the ventilation duct body 3 passes through the multiple telescopic pipes 14 and filter plates 21 inside the box body 2 in turn and then enters the interior of the device body 1, driving the multiple fan blades 11 to rotate, so that the multiple fan blades 11 generate wind power during the rotation process, provide power for the micro-electrostatic discharge component 8, and the excess power is stored for standby through the lithium battery 9; after the air passes through the multiple shells 7, the micro-electrostatic discharge component 8 after being energized generates a strong high-voltage electrostatic field, which can adsorb and filter residual particulate matter in the air, and can also achieve a strong inactivation and disinfecting effect on bacteria and viruses in the air. The air after filtration and sterilization is discharged through the shutters 4, so that the device body 1 can clean and disinfect the discharged air, and no external power supply is required. Wind power is generated with the help of multiple fan blades 11, making full use of wind resources, saving energy, and reducing costs. The micro-electrostatic discharge component 8 and the micro-electrostatic filter 10 used in this application are both uses of the prior art, and no further elaboration is made here.

[0037] If the wind force discharged from the ventilation duct body 3 is small, resulting in the fan blades 11 rotating slowly and being unable to provide sufficient power for the operation of the micro electrostatic discharge assembly 8, the control motor 16 is started to drive the screw rod 19 to rotate, thereby driving the fixing frame 22 to move toward the filter plate 21, so that the telescopic ends of the multiple telescopic pipes 14 extend toward the filter plate 21. Fig.11 As shown, at this time, the telescopic ends of the multiple telescopic ducts 14 are in contact with the filter plate 21, and the wind force discharged to the inside of the box body 2 through the ventilation duct body 3 is adjusted by the telescopic duct 14 to adjust the amount of air passing through it, so that the wind force discharged from the air outlet end of the telescopic duct 14 becomes larger, so that after the wind with increased wind force enters the interior of the device body 1, it can drive the fan blades 11 to rotate rapidly and generate sufficient electric energy for the micro-electrostatic discharge component 8 to use, thereby avoiding the situation where the fan blades 11 rotate slowly, resulting in poor air filtration and disinfection and sterilization effects of the micro-electrostatic discharge component 8.

[0038] The filter plate 21 arranged inside the box body 2 can filter larger impurities in the exhausted air to prevent these impurities from directly entering the interior of the device body 1 and affecting the rotation of the multiple fan blades 11; after the filter plate 21 has been used for a period of time, a large amount of impurities left by the filtered air will accumulate on its surface. At this time, during the idle time of the device body 1, the sealing plate 15 at the bottom of the box body 2 can be rotated downward to open it, and the two second sliders 26 can be controlled to drive the two moving rods 20 to repeatedly move towards and away from each other, thereby driving the two first cleaning brushes 28 to clean the outer wall of one side of the filter plate 21, and the cleaned impurities can be automatically discharged through the discharge port below, thereby achieving the effect of automatically cleaning one side of the filter plate 21.

[0039] After cleaning the outer wall of one side of the filter plate 21, it is necessary to clean the outer wall of the other side of the filter plate 21. At this time, the motor 16 can be controlled to drive the screw rod 19 to rotate a certain angle, so that the state of the rectangular block 25 at this time corresponds to the position of the slot 33, and then the multiple first sliders 24 are controlled to drive the mounting plate 12 to move in the direction close to the filter plate 21, driving the rectangular block 25 to be plugged and adapted to the slot 33. At this time, during the process of the motor 16 driving the screw rod 19 to rotate forwards and backwards, the rotating block 32 and the mounting frame 23 can be synchronously driven to rotate together on the other side of the filter plate 21. With the help of multiple second cleaning brushes, the other side of the filter plate 21 can be cleaned, and during the cleaning process, the multiple third sliders 35 drive the movable plate 34 to retract and retract in the third slide groove to avoid the generation of cleaning dead corners.

[0040] At the same time, the motor 16 drives the screw rod 19 to repeatedly rotate forward and backward, which can drive the fixing frame 22 to repeatedly move toward and away from the mounting plate 12, so that the telescopic end of the telescopic pipe 14 is repeatedly extended and shortened, driving the multi-section telescopic ends of the telescopic pipe 14 to scrape and clean the impurities attached to the inner wall of the telescopic pipe 14 in turn. The impurities cleaned from the inner wall of the telescopic pipe 14 will accumulate at the position between the mounting plate 12 and the ventilation duct body 3. The staff can regularly disassemble the box body 2 from the exhaust port of the ventilation duct body 3 to clean this part of the impurities; or open a discharge port at the bottom of one end of the box body 2 close to the ventilation duct body 3 to quickly discharge this part of the impurities from the inside of the box body 2.

[0041] In the above-mentioned process of cleaning impurities on the inner wall of the telescopic pipe 14, impurities on the inner wall of a telescopic end connected to the fixing frame 22 cannot be cleaned. At this time, the mounting blocks inside the multiple rectangular through grooves 27 can be controlled to drive the electric telescopic rod 29 and the airbag 30 to rotate 90 degrees toward the direction of the mounting plate 12 to be horizontal. Then, the screw rod 19 is controlled to drive the fixing frame 22 to move to the position farthest from the mounting plate 12, and then the multiple telescopic ends are driven to be sleeved on the surfaces of the multiple airbags 30 and the electric telescopic rod 29. The multiple airbags 30 are controlled to be inflated and expanded, so that the wear-resistant fluff layers on the outer walls of the multiple airbags 30 are in contact with the inner wall of the telescopic pipe 14. With the help of the extension and shortening of the telescopic ends of the multiple electric telescopic rods 29, the multiple airbags 30 are driven to move back and forth inside the multiple telescopic ends together, so that the multiple telescopic ends whose inner walls have not been cleaned can be cleaned. The servo motors inside the multiple mounting blocks can also drive the multiple electric telescopic rods 29 and the airbags 30 to rotate inside the multiple telescopic ends together, thereby improving the efficiency of the airbags 30 in cleaning the inner wall of the telescopic end.

[0042] At the same time, after the device body 1 is installed at the exhaust port of the ventilation duct body 3 that has not yet been put into use, in order to prevent small animals such as mice from entering the ventilation duct body 3 and entering the interior of the device body 1 from the exhaust port of the ventilation duct body 3, thereby affecting the subsequent use of the device body 1, the above-mentioned steps of cleaning the inner walls of the telescopic ends of the multiple telescopic pipes 14 with the help of multiple air bags 30 can be repeated, so that the multiple air bags 30 in the inflated state can block the inside of the telescopic ends of the multiple telescopic pipes 14, thereby protecting the device body 1 that has not yet been put into use and preventing small animals such as mice from causing damage to the device body 1.

[0043] If the wind force of the air discharged from the ventilation duct body 3 is too strong, the filter plate 21 slidably installed inside the box body 2 may slide due to the strong wind force. When the filter plate 21 is in use, the two third sliders 35 in the horizontal state may be controlled to move in the two third slide grooves in directions away from each other, thereby driving the two movable plates 34 in the horizontal state to move in directions away from each other, so that the ends of the two movable plates 34 in the horizontal state that are away from each other are tightly pressed against the inner wall of the box body 2, thereby greatly improving the stability of the filter plate 21 inside the box body 2 and avoiding instability of the filter plate 21 when used inside the box body 2.

[0044] Moreover, due to the strong wind force inside the ventilation duct body 3, the multiple blades 11 inside the device body 1 rotate too fast, which increases the eccentricity of the blades 11, destroys the balance of the rotation of the blades 11, makes the blades 11 easy to be damaged and worn, and reduces the service life of the blades 11. At this time, the mounting blocks inside the multiple rectangular through grooves 27 can be controlled to drive the electric telescopic rod 29 and the airbag 30 to rotate downward in the direction of the device body 1 in an inclined state, and then control the two horizontal third sliders 35 to move in the two third slide grooves in a direction close to each other, bringing The ends of the two horizontal movable plates 34 that are away from each other are moved to release the abutment state with the box body 2, and finally the multiple first sliders 24 can be controlled to drive the mounting plate 12 and the screw rod 19 to move toward the filter plate 21, and push the filter plate 21 to move toward the device body 1, so that the multiple electric telescopic rods 29 and the airbags 30 that are in an inclined state at this time can be inserted and sat inside the multiple shells 7, and the multiple airbags 30 are controlled to be inflated and expanded, so as to limit the rotation of the fan blades 11, avoid affecting the rotation balance of the fan blades 11, and improve the service life of the fan blades 11.

[0045] Since the fan blades 11 cannot rotate, wind power generation cannot continue. The excess electrical energy stored in the lithium battery 9 can continue to power the micro-electrostatic discharge component 8, so that the micro-electrostatic discharge component 8 can continue to filter and sterilize the exhaust air.

Obviously, many modifications and changes can be made according to the content of this specification.
