The dust after cleaning will be temporarily stored in the filter assembly, and after the filter assembly is reset, the connected function of the diverter port 1, the diverter port 2 and the connecting port will be utilized to send the cleaned dust into the dust collecting structure for storage, so as to avoid dust accumulation in the air duct affecting the subsequent air intake quality, thereby ensuring the ventilation and filtration efficiency of the filter assembly, reducing the maintenance frequency and improving the life cycle.

DETAILED DESCRIPTION

[0035] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0036] Embodiment 1, as Figure 1As shown, a green building vent filter device comprises two mounting plates 1, the two mounting plates 1 are symmetrically distributed front and back, and grilles 2 are fixedly mounted on the inner surfaces of the two mounting plates 1, the front end of the grille 2 at the rear is fixedly connected to an air supply structure 7, the front end of the air supply structure 7 is fixedly connected to a filter structure 4 fixedly connected to the rear end of the front grille 2, the upper end of the filter structure 4 is fixedly mounted with a cleaning drive structure 3, the right end of the filter structure 4 is fixedly connected to a dust collecting structure 5, and the right end of the cleaning drive structure 3 is fixedly connected to a controller 6;

[0037] Large debris in the air, such as leaves, plastic bags, and petals, which can float in the air, will move with the airflow. The grille 2 set on the outer facade of the wall can prevent these debris from entering the inner side of the ventilation device, thereby preventing large debris from getting stuck and blocking the ventilation system.

[0038] Further, to achieve ventilation effect by supplying air inwards, see Figure 2 The air supply structure 7 includes a support frame 71 fixedly connected to the rear end of the air duct 41, and a plurality of fans 72 are linearly distributed and fixedly connected to the inner surface of the support frame 71. The rear end of the support frame 71 is fixedly connected to the front end of the grille 2 located at the rear, and the wind force and direction of the fan 72 is to blow air away from the air duct 41.

[0039] The fan 72 has a built-in brushless motor, and its power line and control line are connected to the controller 6 through a signal line. The start and stop and speed of the fan are controlled by the controller 6, so that the air intake volume is adjusted according to the needs of the owner. This is a conventional control method, and its principle is similar to that of an old-fashioned ceiling fan switch. It is a mature technical method in the prior art and will not be repeated or demonstrated in the present invention.

[0040] Further, in order to filter the dust in the air drawn by the fan 72, refer to Figure 3 and Figure 4 The filtering structure 4 includes an air duct 41 fixedly connected to the rear end of the grille 2 located at the front and the front end of the air supply structure 7, a filtering assembly 42 is arranged in the middle of the inner surface of the air duct 41, a diversion port 1 43 communicating with the filtering assembly 42 is provided on the left side of the inner surface of the air duct 41 at a position located in front of the filtering assembly 42, a diversion port 2 45 communicating with the dust collecting structure 5 is provided on the right side of the inner surface of the air duct 41 at a position located in the rear of the filtering assembly 42, and a connecting port 46 communicating with the filtering assembly 42 is provided on the right side of the inner surface of the air duct 41 at a position where the filtering assembly 42 is located.

[0041] The air duct 41 is a place where the air sucked in by the fan 72 is processed. The filter component 42 inside it is used to filter the air and is configured with related structures that can perform self-cleaning to ensure that it can still maintain a high air filtration efficiency during long-term operation, thereby reducing the maintenance frequency.

[0042] During the operation of this embodiment, air is drawn through the fan 72, and the small particles of dust and lint therein are filtered and separated by the function of the filter component 42. At the same time, the filter component 42 is periodically cleaned under the control of the controller 6 by the cooperation of the cleaning drive structure 3 and the dust collecting structure 5. After cleaning, the dust will be temporarily stored in the filter component 42, and after the filter component 42 is reset, the connected function of the diverter port 1 43, the diverter port 2 45, and the connecting port 46 is used to send the cleaned dust to the dust collecting structure 5 for storage, so as to avoid dust accumulation in the air duct 41 affecting the subsequent air intake quality, thereby ensuring the ventilation and filtration efficiency of the filter component 42, reducing the maintenance frequency, and improving the life cycle.

[0043] Embodiment 2. Based on embodiment 1, this embodiment filters and cleans dust in the air through filter 1 425, and utilizes the action of cleaning response component 33 to periodically drive relay component 32 to knock downward, thereby pushing frame plate 421 into buffer slot 411, and simultaneously utilizes passive cleaning component 422 to clean the surface of filter 1 425, scrapes off the dust on its surface, and reduces dust accumulation on filter 1 425, and simultaneously cooperates with passive cleaning component 422 through connecting hole 2 423. When connecting hole 2 423 is connected with diversion port 2 45 and connecting port 46 on both sides, the dust is sent from passive cleaning component 422 into dust collecting structure 5 through diversion of diversion port 1 43 and connecting port 46, thereby reducing dust accumulation in passive cleaning component 422 and avoiding affecting subsequent self-cleaning operation.

[0044] Specifically, to drive the filter assembly 42 to perform a cleaning operation, refer to Figure 5 The cleaning drive structure 3 includes a relay component 32 symmetrically distributed on the left and right and fixedly connected to the upper end of the frame plate 421, and a shielding box 31 fixedly installed on the upper end of the air duct 41. A cleaning response component 33 is arranged in the middle of the inner surface of the shielding box 31, and the right end of the shielding box 31 is fixedly connected to the controller 6.

[0045] The cleaning response component 33 is an intermittent mechanism with periodic motion. Under normal ventilation conditions, the operating frequency of the cleaning response component 33 is extremely low, and is set to run once every 10-12 hours through the controller 6. If extreme weather such as haze and dust occurs, the dust and sand content in the incoming air is extremely high. At this time, the load of the filter 425 increases exponentially under the condition of the same incoming air volume, and it is necessary to adjust the operating frequency of the cleaning response component 33 to speed up the self-cleaning efficiency of the filter component 42.

[0046] Further, in order to separate and filter the dust in the air, refer to Figure 6The filter assembly 42 includes a frame plate 421, and a plurality of filter screens 425 are linearly distributed and fixedly connected on the inner surface of the frame plate 421. Passive cleaning components 422 are arranged at the lower ends of the plurality of filter screens 425. A plurality of connecting holes 423 connected to the passive cleaning components 422 are linearly distributed on the left and right ends of the frame plate 421. The upper end of the frame plate 421 is fixedly connected to the cleaning drive structure 3.

[0047] The filter 425 is used to intercept dust and impurities in the incoming air flow to prevent these pollutants from entering the room, and the cooperation between the passive cleaning component 422 and the air duct 41 can clean the filter 425 when the filter component 42 is lowered by the relay component 32.

[0048] Further, in order to realize that when the filter screen 1 425 and the support plate 2 4221 move downward following the movement of the frame plate 421, the compression spring 2 4222 is driven to slide outward and fit with the surface of the filter screen 1 425, see Figure 7 and Figure 8 The passive cleaning component 422 includes a support plate 4221 fixedly connected to the lower end of the adjacent filter screen 425, a rounded corner is provided on the front side of the upper end of the support plate 4221, and a fixing box 4224 fixedly connected to the inner walls of the left and right sides of the air duct 41 is arranged at its front end, and a compression spring 4222 is symmetrically fixedly connected to the front of the inner surface of the fixing box 4224, and the rear ends of the two compression springs 4222 are fixedly connected to an arc scraper 4223 slidingly connected to the inner surface of the fixing box 4224, and the rear end of the arc scraper 4223 is in close contact with the front end of the support plate 4221.

[0049] When the frame plate 421 descends, it will simultaneously drive the filter screen 1 425 and the support plate 2 4221 to move downward. However, since the fixing box 4224 is fixed to the inner wall of the air duct 41, the fixing box 4224 will not move. At this time, the arc scraper 4223 in the support plate 2 4221 will slide outward under the action of the compression spring 2 4222 when passing through the arc surface of the support plate 2 4221. At this time, the compression spring 2 4222 will fit with the front end of the filter screen 1 425, thereby scraping off the dust on the surface of the filter screen 1 425 and making it fall into the fixing box 4224. Since the front part of the fixing box 4224 is solid, the dust entering the inside will not be affected by the air intake airflow.

[0050] When the frame plate 421 is reset, due to the pressure of the support plate 4221, the arc scraper 4223 returns to the inner cavity of the fixed box 4224. At this time, the front part of the compression spring 4222 is closed by the compression spring 4222, and the dust is temporarily stored in the fixed box 4224.

[0051] Further, in order to clean the dust inside the fixed box 4224, refer to Figure 8The left and right ends of the fixed box 4224 are both provided with a connecting hole 4225 connected to its inner cavity. The two connecting holes 4225 are connected to the adjacent connecting holes 423 in the initial state. Several connecting holes 423 located on the left side are connected to the diversion port 1 43, and several connecting holes 423 located on the right side are connected to the connecting port 46.

[0052] When the connecting hole 1 4225 is reset, it will be connected with the connecting hole 2 423 on both sides. At this time, a branch passage is formed through the diversion port 1 43, the right connecting hole 2 423, the connecting hole 1 4225, the fixing box 4224, the left connecting hole 2 423, and the connecting port 46. At this time, the airflow can enter the dust collecting structure 5 through this passage.

[0053] Embodiment 3: Based on embodiment 2, this embodiment further utilizes the cooperation between the connecting rod 336 and the telescopic rod 335 to drive the telescopic rod 335 to rotate periodically along the fulcrum between the connecting rod 336 and the support plate 331, thereby driving the sliding rod 333 to move downward along the limiting cylinder 332, thereby realizing the use of the rapid impact of the sliding rod 333 and the contact block 334 to drive the rubber ball 321 to move downward, and after the connecting rod 322 in the rubber ball 321 contacts the notch plate 44, the compression spring 1 324 and the buffer spring 424 are subjected to the maximum force, and at this time, the contact block 334 rises under the action of the telescopic rod 335, but under the action of the connecting rod 322, the rubber ball 321 rises with a delay relative to the contact block 334, so that after the contact block 334 leaves the upper end of the rubber ball 321, under the overlapping action of the compression spring 1 324 and the buffer spring 424, the frame plate 421 and the rubber ball 321 rebound rapidly and produce a small amplitude oscillation, thereby promoting the dust to fall off the surface of the filter screen 425.

[0054] Specifically, in order to realize the self-cleaning of the frame plate 421, refer to Fig. 9 The relay assembly 32 includes a rubber ball 321, the lower end of the rubber ball 321 is fixedly connected to a damping ring 323, the lower end of the damping ring 323 passes through the upper end of the slot plate 44 and extends to the lower end of the slot plate 44 and is fixedly connected to the upper end of the frame plate 421, a connecting rod 322 is fixedly connected to the middle and upper part of the outer surface of the damping ring 323, and the lower end of the rubber ball 321 is fixedly connected to a compression spring 324 fixedly connected to the upper end of the slot plate 44.

[0055] Furthermore, when the rubber ball 321 is delayed in rising, the filter assembly 42 is caused to vibrate by utilizing the buffer springs 424 on both sides and the compression spring 324, thereby further promoting the dust to fall off from the surface of the filter screen 425. Fig.10A buffer groove 411 is provided on the inner surface of the air duct 41 corresponding to the position of the frame plate 421, and a plurality of buffer springs 424 fixedly connected to the bottom wall of the inner cavity of the buffer groove 411 are linearly distributed and fixedly connected at the lower end of the frame plate 421. The inner surface of the buffer groove 411 is slidably connected to the lower part of the outer surface of the frame plate 421, and a notch plate 44 slidably connected to the outer surface of the frame plate 421 is fixedly connected to the top wall of the inner cavity of the air duct 41 corresponding to the position of the buffer groove 411.

[0056] The rubber ball 321 is fixed to the upper side of the frame plate 421. When it moves downward under the action of the cleaning response component 33, it can synchronously drive the frame plate 421 to descend, and compress the compression spring 324 and the buffer spring 424 on the lower side of the frame plate 421 to store energy. A connecting rod 322 is also provided on the outer surface of the damping ring 323, which can provide a certain resistance, so that the cleaning response component 33 can temporarily remain motionless after leaving the rubber ball 321, and then quickly bounce up and form aftershocks with the help of the elastic release of the compression spring 324 and the buffer spring 424, thereby further promoting the shedding of dust on the surface of the filter screen 425.

[0057] Further, in order to periodically knock the rubber ball 321 to drive the frame plate 421 to move downward, refer to Fig. 9 The cleaning response component 33 includes a support plate 331 fixedly connected to the middle part of the inner surface of the shielding box 31, and two mutually meshing gears 337 are symmetrically fixedly connected to the front end of the support plate 331, and the front ends of the two gears 337 are eccentrically rotatably connected to the connecting rod 336, and the upper ends of the two support plates 331 are rotatably connected to the telescopic rods 335, and the middle parts of the rear ends of the two telescopic rods 335 are rotatably connected to the front end of the support plate 331 through the limiting column, and the two telescopic rods 335 face oppositely and their output end piston rods are rotatably connected to the sliding rods 333 respectively, and the outer surfaces of the two sliding rods 333 are slidably connected to the limiting cylinders 332 fixedly connected to the top wall of the inner cavity of the shielding box 31, and the lower ends of the two sliding rods 333 are fixedly connected to the contact blocks 334 located above the adjacent rubber balls 321, and the rear end of the support plate 331 is fixedly connected to the driving motor 338 connected to the controller 6 through the control line and connected to one of the gears 337.

[0058] First, the driving motor 338 drives one of the gears 337 to rotate. During the rotation process, since the gear 337 is eccentrically connected to the connecting rod 336, and the telescopic rod 335 has its fulcrum located in front of the supporting plate 1 331, the other side is restricted by the sliding rod 333 and the limiting cylinder 332 to only move in a circle around its fulcrum.

[0059] Therefore, with the cooperation of the connecting rod 336 and the gear 337, the connecting rod 336 will move periodically under the limit of one side of the telescopic rod 335, and the connecting rod 336 will drive one end of the telescopic rod 335 to rise and fall cyclically, thereby driving the sliding rod 333 and the contact block 334 to move up and down cyclically. Due to the characteristics of the eccentric wheel and the lever, the downward impact force is greater than the upward impact force, thereby producing a knocking and hammering effect on the rubber ball 321. At the same time, both are made of rubber and will not generate excessive noise.

[0060] Further, in order to collect and process the dust in the fixed box 4224 and to speed up the action frequency of the cleaning response component 33 and improve the cleaning rate when the filter screen 425 is blocked, refer to Fig.11 The dust collecting structure 5 includes a dust filter box 51 fixedly connected to the right end of the air duct 41, a filter screen 52 is fixedly connected to the middle of the inner surface of the dust filter box 51, the front left part of the inner surface of the dust filter box 51 is connected to the connecting port 46, the rear left part of the inner surface of the dust filter box 51 is connected to the diversion port 2 45, and a dust box 53 is slidably connected to the lower part of the inner surface of the dust filter box 51. The rear end of the dust box 53 passes through the front end of the mounting plate 1 at the rear and extends to its rear end. A wind speed sensor 54 connected to the controller 6 through a signal line is fixedly connected to the rear end of the inner surface of the dust filter box 51.

[0061] In the initial state, the branch passage formed by the diverter port 1 43, the right connecting hole 2 423, the connecting hole 1 4225, the fixed box 4224, the left connecting hole 2 423, and the connecting port 46 has a narrow path, a large relative resistance, and a relatively small airflow. At this time, the electrical signal transmitted by the wind speed sensor 54 is also very small. The airflow can slowly drive the dust in the fixed box 4224 into the dust filter box 51 through this passage, and is blocked by the filter screen 2 52 and falls into the dust collection box 53 for storage. The airflow will return to the inner side of the air duct 41 through the diverter port 2 45.

[0062] When filter 425 is close to being blocked, the resistance areas of the two paths are balanced. At this time, the wind speed detected by the wind speed sensor 54 increases, and the signal provided to the controller 6 increases. The controller 6 controls the drive motor 338 to speed up the operation frequency, thereby improving the cleaning rate and ensuring the filtration efficiency of filter 425, until the difference between the resistances of the two paths increases, the data measured by the wind speed sensor 54 decreases, and the controller 6 controls the drive motor 338 to reduce the operating frequency.

[0063] It should be specially noted that the controller 6 in the present invention is a conventional control device, and this structure has been widely used in the prior art. In the present invention, it is only used to realize the functions of controlling the rotation speed of the fan 72, the operating frequency of the drive motor 338, and receiving the feedback signal of the wind speed sensor 54. Its control methods are all conventional technical means in the prior art. In the present invention, its internal structure, operating principle, wiring, and control method are no longer displayed or elaborated.

[0064] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention to be protected. The scope of protection of the present invention is defined by the attached claims and their equivalents.
