DETAILED DESCRIPTION

[0028] 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 described below in conjunction with specific implementation methods.

[0029] like Figure 1-8 As shown, a vent device for an intelligent building includes a ventilation duct 1, a fan 4 is fixedly connected to the front portion of the inner surface of the ventilation duct 1, a replacement device 5 is slidably connected to the middle portion of the inner surface of the ventilation duct 1, the lower end, left end and right end of the ventilation duct 1 are commonly fixedly connected to an outer shell 2, a drawer 3 is slidably connected to the bottom wall of the inner surface of the outer shell 2, and an erasing device 6 is fixedly connected to the middle portion of the lower end of the ventilation duct 1.

[0030] The specific structural type, shape and size of the shell 2 mentioned above only need to meet the requirements of supporting and installing other components inside the shell 2 in practice, ensuring the stability of other components inside the shell 2 during use, and ensuring aesthetics.

[0031] The drawer 3 mentioned above is used to collect impurities cleaned from the surface of the filter plate to facilitate cleaning of the impurities, the fan 4 mentioned above is used to facilitate ventilation inside the building, the replacement device 5 mentioned above is used to facilitate replacement of the filter plate, and the wiping device 6 mentioned above is used to improve the efficiency of cleaning impurities on the surface of the filter plate.

[0032] Specifically, in order to facilitate the replacement of the filter plate, avoid manual replacement, and reduce the workload of the staff, refer to Figure 2-3 In the embodiment, the replacement device 5 includes a filter plate 1 51 and a filter plate 2 55, the left portion of the rear end of the filter plate 1 51 and the left portion of the front end of the filter plate 2 55 are both fixedly connected with a rack 52, the ends of the two racks 52 close to each other are meshed and connected with a gear 1 54, and the left end of the gear 1 54 is fixedly connected with a motor 1 53;

[0033] For further information, see Figure 3 In the embodiment, the filter plate 1 51 and the filter plate 2 55 both penetrate the lower end of the ventilation pipe 1 and extend to the inside of the top wall of the inner surface of the ventilation pipe 1 and are slidably connected to the ventilation pipe 1. The filter plate 1 51 is placed in front of the filter plate 2 55. The motor 1 53 is fixedly connected to the ventilation pipe 1. The two racks 52 both penetrate the ventilation pipe 1 and extend to the inside of the ventilation pipe 1.

[0034] It can be seen from this that in practice, the initial state of the replacement device 5 is that the filter plate 1 51 is placed on the inner surface of the ventilation pipe 1, the filter plate 2 55 is placed at the lower part of the ventilation pipe 1, and the filter plate 2 55 is a clean filter plate. When the filter plate 1 51 needs to be replaced, the motor 1 53 is started, and the driving gear 1 54 starts to rotate backward, which can drive the front rack 52 to move downward and drive the rear filter plate 2 55 to move upward. When the rear filter plate 2 55 is placed inside the top wall of the inner surface of the ventilation pipe 1, the driving motor 1 53 is stopped. At this time, the filter plate 1 51 is placed at the lower part of the ventilation pipe 1, that is, the replacement of the filter plate 1 51 is completed, and the filter plate 2 55 can continue to be used to filter impurities in the air;

[0035] In addition, at this time, the upper part of the filter plate 1 51 and the upper part of the rack 52 fixedly connected thereto are placed inside the bottom wall of the inner surface of the ventilation duct 1, and the lower part of the filter plate 2 55 and the lower part of the rack 52 fixedly connected thereto are also placed inside the bottom wall of the inner surface of the ventilation duct 1, and the through grooves opened on the bottom wall of the inner surface of the ventilation duct 1 for the sliding of the filter plate 1 51, the filter plate 2 55 and the rack 52 are blocked to prevent unfiltered air from continuously entering the interior of the building.

[0036] Specifically, in order to avoid manual cleaning of impurities on the filter plate surface and further improve the efficiency of impurity cleaning, refer to Figure 4-6 In the embodiment, the erasing device 6 includes a second driving assembly 61, a rotating assembly 62 is fixedly connected to the lower part of the second driving assembly 61, and a friction track 63 is closely attached to the right part of the rotating assembly 62;

[0037] For further information, see Figure 4 , in the embodiment, the friction track 63 is fixedly connected to the right portion of the lower end of the ventilation pipe 1;

[0038] For further information, see Figure 5 In the embodiment, the driving assembly 2 61 includes a motor 2 611, a rotating shaft 2 613 and a rotating shaft 3 614. The coupling at the output end of the motor 2 611 is fixedly connected to two bevel gears 612 through the rotating shaft 1. The two bevel gears 612 are meshed with each other. The coupling at the output end of the motor 2 611 is fixedly connected to the fan 4 through the rotating shaft 1. The motor 2 611 is fixedly connected to the ventilation pipe 1. The two bevel gears 612 are rotatably connected to the ventilation pipe 1 through a connecting plate. The bevel gear 612 located on the right is fixedly connected to the rotating shaft 2 613. The rotating shaft 3 614 and the rotating shaft 2 613 are connected together through two pulleys and a transmission belt.

[0039] For further information, see Figure 6In the embodiment, the rotating assembly 62 includes four gears 621, the outer surfaces of the four gears 621 are meshed and connected with a chain 622, the right ends of the four gears 621 are rotatably connected with a fixing frame 623, the left part of the chain 622 is rotatably connected with two roller brushes 624, and the left part of the outer surface of the central axis of the two roller brushes 624 is fixedly connected with a friction wheel 625;

[0040] The width of the filter plate 51 mentioned above is smaller than the distance between the fixed frame 623 and the friction track 63. The ventilation pipe 1 mentioned above is located on the left and right sides of the filter plate 51 and is fixedly connected with two extension plates for the filter plate 51 to move downward to below the upper part of the chain 622. The gear 54 mentioned above is lower than the upper position of the friction track 63, so that the roller brush 624 can pass smoothly through the lower part of the filter plate 51 during operation.

[0041] The specific structural type, shape and size of the fixing frame 623 mentioned above only need to meet the requirements of supporting and installing the chain 622 in practice, ensure the stability of the chain 622 during use, and ensure the appearance.

[0042] The vertical position of the chain 622 mentioned above corresponds to the position of the filter plate 1 51 and the filter plate 2 55 , and can just drive the roller brush 624 to sweep and clean the impurities on the end surfaces of the filter plate 1 51 and the filter plate 2 55 .

[0043] It can be seen that in practice, when the second motor 611 is started to drive the fan 4 to ventilate the room, the second shaft 613 can be driven to rotate by the two meshing bevel gears 612, and the two pulleys and the transmission belt can be used to drive the third shaft 614 to start rotating. During the rotation process, the third shaft 614 can drive the second gear 621 fixedly connected thereto to rotate, and can drive the chain 622 to start rotating.

[0044] In addition, since there is a chain 622 meshingly connected to the inner surface of the chain 622 on all sides, when the gear 2 621 fixedly connected to the rotating shaft 3 614 rotates, the chain 622 drives the other three gear 2 621 to start rotating, and the chain 622 can rotate within the trajectory restricted by the four gear 2 621, and can drive the two roller brushes 624 to start rotating along the trajectory of the chain 622. At this time, the impurities on the surface of the replaced filter plate 51 can be swept and cleaned. As the filter plate 51 descends, the friction between the surface of the filter plate 51 and the roller brush 624 is increased, thereby further improving the sweeping efficiency.

[0045] Specifically, in order to further improve the cleaning rate of impurities on the filter plate surface and improve the cleanliness of the cleaning, refer to Figure 7-8In the embodiment, the fixing frame 623 is fixedly connected to the ventilation pipe 1, the two friction wheels 625 are in close contact with the inner surface of the friction track 63, the rotating shaft 3 614 is rotatably connected to the fixing frame 623, and the four gears 2 621 are rotatably connected to the fixing frame 623;

[0046] It can be seen from this that in practice, when the chain 622 starts to drive the two roller brushes 624 to start rotating along the trajectory of the chain 622 to sweep the end surface of the filter plate 1 51 or the filter plate 2 55, the friction wheel 625 fixedly connected to the left end of the two roller brushes 624 will start to rotate in the slide groove of the friction track 63. When the roller brushes 624 move, they can cooperate with the friction coefficient of the friction wheel 625 and the friction track 63 to generate friction force, causing the two roller brushes 624 to rotate. The two roller brushes 624 rotate along the trajectory of the chain 622 and then rotate at the same time, further improving the efficiency of sweeping impurities on the end surface of the filter plate 1 51 or the filter plate 2 55.

[0047] The ventilation device mentioned above is an integral part of the intelligent building as an optimized whole. It has the characteristics of reasonable project investment, highly automatic equipment, scientific information management, high-quality and efficient service, flexible and convenient use, and safe and comfortable environment. It is a modern ventilation device that can adapt to the needs of the development of an information society.

[0048] It should be noted that the specific installation method, circuit connection method and control method of the motor 2 611 and the motor 1 53 used in the present invention are all conventional designs and will not be elaborated in detail in the present invention.
