Description

Technical Field

[0001] The invention relates to the technical field of doors and windows, and specifically discloses an intelligent ventilation device for a fresh air window. Background Art

[0002] When the indoor carbon dioxide concentration is 1000-2000ppm, humans will feel that the air is turbid and begin to feel drowsy. When it is 2000-5000ppm, they will feel headache, drowsiness, dullness, inability to concentrate, accelerated heartbeat, mild nausea, etc. In order to keep warm in winter, people are used to keeping windows and doors closed. Over time, the carbon dioxide concentration will decrease. Scientists have determined that when the air humidity is higher than 65% or lower than 38%, the bacteria reproduce fastest; when the relative humidity is 45-55%, the mortality rate of bacteria is higher. Because air humidity affects human health, people should not only pay attention to temperature and whether it is sunny or rainy in their daily lives, but also pay attention to the air humidity and its changes around them at all times.

[0003] Existing ventilation devices are all manually controlled. When we feel the need to ventilate, the concentration of carbon dioxide and humidity are often lower than our adaptation values, which will cause harm to the body in the long run.

[0025] In this embodiment: when the indoor air API is too large, the controller 19 starts the servo motor 10, and the servo motor 10 drives one of the baffles 5 to rotate through the first rotating shaft 6, and then drives multiple baffles 5 to rotate synchronously through the first rotating shaft 6, the first connecting rod 7, the second rotating shaft 8 and the second connecting rod 9 on the other side, so that the multiple baffles 5 rotate to the horizontal, so that the external air can enter the room through the rectangular frame 2, and at the same time, the controller 19 starts the fan 3, and the indoor and outdoor air are forced to be exchanged through the fan 3;

[0026] On the contrary, when the outdoor air quality (AQI) is too high, the controller 19 drives the multiple baffles 5 to rotate to a parallel state through the servo motor 10, so that the multiple baffles 5 close the rectangular frame 2 to prevent outdoor air from entering the room. The present invention can automatically open or close the ventilation system according to the outdoor and indoor air quality, and has a good use effect.

[0027] As a technical optimization solution of the present invention, the outer wall of the rectangular frame 2 is installed with a first air quality monitor 20 and a second air quality monitor 21 which are respectively located on two sides of the window body 1 .

[0028] In this embodiment: the first air quality monitor 20 and the second air quality monitor 21 can both detect carbon dioxide, PM2.5, TVOC and temperature and humidity at the same time (the air quality monitor is a prior art and will not be described in detail here), and are installed indoors and outdoors respectively.

[0029] As a technical optimization solution of the present invention, the clamping mechanism includes a shell 12 fixedly connected to the outer wall of the rectangular frame 2, two symmetrically distributed slide bars 13 are fixedly connected between the upper and lower end surfaces inside the shell 12, and the upper and lower sides of the outer walls of the two slide bars 13 are slidably connected with slide plates 14, and the outer walls opposite to each other of the two slide plates 14 are fixedly connected with a third connecting rod 15 extending to the outside of the rectangular frame 2, and the other ends of the two third connecting rods 15 are fixedly connected with a fixing plate 16, and the outer walls opposite to the two fixing plates 16 are fixedly connected with a clamping block 17 extending to the inside of the rectangular frame 2, and the outer wall of the filter screen 4 is provided with a frame 11 slidably connected to the rectangular frame 2, and the upper and lower end surfaces of the frame 11 are provided with a clamping groove matching the clamping block 17;

[0030] The clamping mechanism also includes a gear 22 rotatably connected to the inside of the rectangular housing 12 via a connecting shaft, and opposite outer walls of the two slide plates 14 are fixedly connected with spur racks 23 meshing with the gear 22 .

[0031] In this embodiment: one of the fixing plates 16 is pulled outward, and the fixing plate 16 further drives the slide plate 14 to slide outward along the slide bar 13 through the third connecting rod 15, and compresses the spring 18, and then drives the gear 22 to rotate through the spur rack 23, and then drives the other slide plate 14 to slide synchronously outward along the slide bar 13 through another spur rack 23, and then drives the other fixing plate 16 to slide outward through the third connecting rod 15, and the two fixing plates 16 further drive the two clamping blocks 17 to slide synchronously outward and disengage from the clamping groove, so that the frame 11 can be pulled out, and after the new frame 11 and the filter screen 4 are slid into the rectangular frame 2, the fixing plate 16 is released, and the two fixing plates 16 move relative to each other under the elastic force of the spring 18, thereby driving the two clamping blocks 17 to re-enter the clamping groove to fix the frame 11. The present invention facilitates the installation and removal of the filter screen 4 by clamping the filter screen 4 to the inside of the rectangular frame 2, and the use effect is good.

[0032] As a technical optimization solution of the present invention, two springs 18 located between the slide plate 14 and the inner wall of the shell 12 are sleeved on the outer walls of the two slide bars 13 .

[0033] In this embodiment, the elastic force of the spring 18 facilitates the clamping block 17 to be clamped into the clamping slot.

[0034] As a technical optimization solution of the present invention, the outer walls of the two fixing plates 16 and the outer wall of the frame 11 are both provided with handles.

[0035] In this embodiment, a handle is provided to facilitate pulling the fixing plate 16 and the frame 11 .

[0038] The working principle and use process of the present invention are as follows: when the first air quality monitor 20 (or the second air quality monitor 21) detects that the (API) of the indoor air is too large, the controller 19 starts the servo motor 10, and the servo motor 10 drives one of the baffles 5 to rotate through the first rotating shaft 6, and then drives the multiple baffles 5 to rotate synchronously through the first rotating shaft 6, the first connecting rod 7, the second rotating shaft 8 and the second connecting rod 9 on the other side, so that the multiple baffles 5 rotate to a horizontal state, so that the external air can enter the room through the rectangular frame 2. At the same time, the controller 19 starts the fan 3, and the indoor and outdoor air are forced to be exchanged by the fan 3. When the first air quality monitor 20 (or the second air quality monitor 21) detects that the (AQI) of the outdoor air is too large, the controller 19 drives the multiple baffles 5 to rotate to a parallel state through the servo motor 10, so that the multiple baffles 5 close the rectangular frame 2 to prevent the outdoor air from entering the room. The present invention can automatically open or close the ventilation system according to the outdoor and indoor air quality, and the use effect is good;

[0039] When replacing the filter screen 4, one of the fixing plates 16 is pulled outward, and the fixing plate 16 further drives the slide plate 14 to slide outward along the slide bar 13 through the third connecting rod 15, and compresses the spring 18, and then drives the gear 22 to rotate through the spur rack 23, and then drives the other slide plate 14 to slide synchronously outward along the slide bar 13 through another spur rack 23, and then drives the other fixing plate 16 to slide outward through the third connecting rod 15, and the two fixing plates 16 further drive the two clamping blocks 17 to slide synchronously outward and disengage from the clamping groove, so that the frame 11 can be pulled out, and after the new frame 11 and the filter screen 4 are slid into the rectangular frame 2, the fixing plate 16 is released, and the two fixing plates 16 move relative to each other under the elastic force of the spring 18, thereby driving the two clamping blocks 17 to re-enter the clamping groove to fix the frame 11. The present invention facilitates the installation and removal of the filter screen 4 by clamping the filter screen 4 to the inside of the rectangular frame 2, and has a good use effect.
