Detailed implementation manners

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0027] To make the above objects, features, and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below in conjunction with the drawings and specific implementation manners.

[0028] Referring to Figure 1-7 , the present invention provides an automatic fluff-removing ventilation window, including:

[0029] A filter frame 4, a filter net 5 is fixedly connected inside the filter frame 4, the filter frame 4 is fixedly connected to the base, an installation cavity is provided inside the base, a sealing cover is detachably connected to the installation cavity, and a fluff discharge port 24 is provided on the bottom surface of the filter frame 4;

[0030] A fluff-removing assembly, the fluff-removing assembly includes a driving mechanism and a scraping brush 10, the driving mechanism is arranged on the filter frame 4, the scraping brush 10 abuts against the filter net 5, and the driving mechanism is in transmission connection with the scraping brush 10,

[0031] A negative pressure assembly, the negative pressure assembly includes a funnel 23, a fan 7 and a filter element 22, the funnel 23 is fixedly connected inside the installation cavity, the funnel 23 is communicated with the fluff discharge port 24, the fan 7 is fixedly connected inside the installation cavity, a filter element 22 is arranged between the fan 7 and the funnel 23, and the air outlet end of the fan 7 is communicated with an external discharge pipe 29, and the external discharge pipe 29 extends out of the installation cavity.

[0032] In this device, the filter screen 5 is used to filter sundries such as catkins, the scraping brush 10 is used to scrape off the sundries attached to the filter screen 5, the driving mechanism is used to drive the scraping brush 10 to move, the scraping brush 10 is closely attached to the air inlet surface 6 of the filter screen 5, the driving mechanism drives the scraping brush 10 to fit the air inlet surface 6 of the filter screen 5 and reciprocate relative to the filter screen 5, sweeping the catkins in the filter screen 5 into a group and moving them near the catkin discharge port 24. The funnel 23 has a large inner diameter end and a small inner diameter end, the large inner diameter end is docked with the catkin discharge port 24, the filter element 22 is arranged at the small inner diameter end of the funnel 23, and the outer discharge pipe 29 is isolated from the installation cavity. When the fan 7 works, the air inlet of the fan 7 directly sucks the air in the sealed cavity. The inside of the funnel 23 is in a negative pressure state, sucking the catkins at the catkin discharge port 24. All the gas inside the funnel 23 also passes through the filter element 22, and finally the air is discharged to the outside through the outer discharge pipe 29. The fan 7 is connected to the funnel 23 through the sealed cavity. Therefore, the position of the fan 7 can be arbitrarily set inside the installation cavity without being docked below the funnel 23. The fan 7 is easy to install and can reduce the axial height of the automatic catkin removal ventilation window. The filter element 22 can be implemented as a filter screen and can be used to filter catkins.

[0033] In a further optimized solution, an inclined plate 20 is fixedly connected inside the filter frame 4. The inclined plate 20 is located below the filter screen 5. The bottom end of the inclined plate 20 is docked with the catkin discharge port 24. A transverse sealing brush 26 is fixedly connected to the lower end of the inclined plate 20. The transverse sealing brush 26 is on the same plane as the inclined plate 20, and the transverse sealing brush 26 is located above the catkin discharge port 24.

[0034] After the scraping brush 10 scrapes off the catkins, the inclined plate 20 facilitates the catkins to enter the catkin discharge port 24. In this embodiment, when installing the inclined plate 20, the inclined plate 20 can be installed on the catkin discharge port 24 to reduce the area of the catkin discharge port 24 and increase the adsorption force generated by the negative pressure fan at the catkin discharge port 24. An acute angle is formed between the inclined plate 20 and the filter screen 5. The transverse sealing brush 26 is arranged at the end of the inclined plate 20, and the transverse sealing brush 26 is arranged on the same plane as the inclined plate 20. The transverse sealing brush 26 is located above the catkin discharge port 24. The transverse sealing brush 26 can block the reverse movement of the catkins in the sealed cavity and prevent the catkins from leaking out.

[0035] In a further optimized solution, an inclined scraping plate 27 is fixedly connected to the filter frame 4. A fixing hole is opened at the top end of the inclined scraping plate 27, and a bolt is inserted into the fixing hole. The inclined scraping plate 27 is fixedly connected to the filter frame 4 through the bolt. The inclined scraping plate 27 is located above the catkin discharge port 24 and is inclined downward.

[0036] The end of the inclined scraper 27 is arranged in a comb shape or a serrated shape. When the scraping brush 10 moves downward from top to bottom, when the scraping brush 10 passes through the inclined surface of the inclined scraper 27, the contact between itself and the serrated end or the comb end of the inclined scraper 27 is reduced. When the scraping brush 10 moves upward from bottom to top, the scraping brush 10 contacts the serrated end of the inclined scraper 27, thereby cleaning the catkins wrapped around the scraping brush 10. The cleaned catkins are then sucked away by negative pressure, which can ensure that the scraping brush 10 can clean the filter screen 5 again in a clean state.

[0037] In a further optimized solution, the driving mechanism part includes a motor 11 and a driving belt 13. Slide rails 12 and vertical sealing brushes 17 are fixedly connected to both sides inside the filter frame 4. Both ends of the scraping brush 10 are slidably connected to the slide rails 12. A number of first bearings 16 and a number of auxiliary bearings 14 are fixedly connected inside the filter frame 4. The first bearings 16 and the auxiliary bearings 14 are located on both sides of the filter screen 5. A first rotating shaft 15 is rotatably connected inside the first bearings 16 and the auxiliary bearings 14. The motor 11 is in transmission connection with the first rotating shaft 15 through the driving belt 13. A number of second bearings are fixedly connected inside the filter frame 4. A second rotating shaft is rotatably connected inside the second bearings. An auxiliary transmission belt 28 is rotatably connected between the first rotating shaft 15 and the second rotating shaft. Both ends of the scraping brush 10 are in transmission connection with the driving belt 13 and the auxiliary transmission belt 28 respectively. The vertical sealing brush 17 abuts against the scraping brush 10.

[0038] The motor 11 drives the driving belt 13 to rotate, the driving belt 13 drives the first rotating shaft 15 to rotate, the first rotating shaft 15 drives the auxiliary transmission belt 28 to rotate. The auxiliary transmission belt 28 is rotatably connected to the first rotating shaft 15 and the second rotating shaft. The driving belt 13 and the auxiliary transmission belt 28 drive the scraping brush 10 to move up and down; both ends of the scraping brush 10 are provided with sliders, the sliders cooperate with the slide rails 12, and the vertical sealing brush 17 abuts against the scraping brush 10. When the scraping brush 10 is pulled by the transmission belt 13 to move, the vertical sealing brush 17 can timely fill the gap during the movement of the scraping brush 10, which can prevent catkins from leaking out from the gap between the scraping brush 10 and the filter frame 4 and avoid catkins affecting the cooperation between the slider and the slide rail 12.

[0039] In a further optimized solution, toothed plates 19 are fixedly connected to both ends of the scraping brush 10, and the driving belt 13 and the auxiliary transmission belt 28 are toothed belts, and the toothed belts are fixedly connected to the toothed plates 19.

[0040] The driving belt 13 and the auxiliary transmission belt 28 are in transmission connection with the scraping brush 10 through the toothed plates 19. After the toothed belts are fixedly connected to the toothed plates 19, the up and down movement of the scraping brush 10 will be more stable. Because the scraping brush 10 only needs to move up and down, the position where the toothed belts are fixedly connected to the toothed plates 19 only needs to move on the vertical plane.

[0041] For a further optimized solution, several travel switches 18 are fixedly connected inside the filtering frame 4. The several travel switches 18 are located at the top and the base of the filtering frame 4. The travel switches 18 are arranged on the moving path of the scraping brush 10, and the travel switches 18 are electrically connected to the motor 11.

[0042] When the scraping brush 10 moves downward, the scraping brush 10 will touch the travel switch 18, and the travel switch 18 is triggered to make the scraping brush 10 move upward. Correspondingly, a travel switch 18 is provided below the first bearing 16. When the scraping brush 10 triggers the upper travel switch 18, the rotation direction of the motor 11 also changes correspondingly, causing the scraping brush 10 to move downward.

[0043] For a further optimized solution, a reminder component is also arranged on the filtering frame 4. The reminder component includes a pressure sensor and an acoustic-optic element. The pressure sensor and the acoustic-optic element are electrically connected. The pressure sensor is arranged on the bottom surface of the filtering element 22, and the acoustic-optic element is fixedly connected to the filtering frame 4. A drawer 21 is slidably arranged between the funnel 23 and the blower 7. The bottom of the drawer 21 is provided with a hollow, and the filtering element 22 is fixedly connected to the hollow position of the drawer 21.

[0044] Since the catkins collected by the filtering element 22 are in a clump shape, after the equipment runs for a long time, the catkins will block the filtering element 22, resulting in a decrease in the negative pressure inside the funnel 23. When the filtering element 22 is blocked by the catkins, the suction force of the blower 7 on the filtering element 22 will increase, and the pressure received by the pressure sensor will also increase correspondingly. When the pressure of the pressure sensor exceeds the preset pressure, the acoustic-optic element starts to work, reminding the operator to open the drawer 21 to clean the catkins on the filtering element 22.

[0045] For a further optimized solution, a flexible connecting piece 9 is fixedly connected to the filtering frame 4.

[0046] The filtering frame 4 is connected to the outside through the flexible connecting piece 9. Within a reasonable error range, it can ensure a stable connection between the filtering frame 4 and the outside. The flexible connection can also isolate the transmission of vibration.

[0047] Install this device on the window, with the air inlet surface 6 facing the outside and the air outlet surface 2 facing the inside. When the sensor detects that the catkins on the filter net 5 have accumulated to a certain amount, the automatic catkin-removing ventilation window starts to work. Turn on the blower 7, and the motor 11 drives the scraping brush 10 to move up and down to scrape the catkins on the air inlet surface of the filter net 5 and form catkin clumps at the catkin discharge port 24 at the bottom of the filtering frame 4. The catkins are sucked into the catkin discharge port 24 by the negative pressure component and then enter the funnel 23. The air passes through the filtering element 22 and is discharged from the outer discharge pipe to the outside of the filtering frame. The catkin clumps and flying catkins fall on the filtering element 22 of the drawer 21. When the catkins are full, pull out the drawer 21, clean the drawer 21, and then install it back in place.

Without departing from the design spirit of the present utility model, various deformations and improvements made by those of ordinary skill in the art to the technical solutions of the present utility model shall fall within the protection scope determined by the claims of the present utility model.
