[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] Reference Figure 1 - Figure 4 The utility model provides an embodiment: a ventilation device for an assembled building wall of a construction project, comprising a ventilation main body 1, a filter screen 2 is slidably connected inside the ventilation main body 1, a mounting ring 3 is rotatably connected inside the ventilation main body 1, a plurality of card slots 25 are opened at the front of the ventilation main body 1, a baffle 6 is slidably connected inside the card slot 25, a thin rope 8 is arranged between the baffle 6 and the mounting ring 3, a spring 7 is sleeved on the outside of the thin rope 8, a plug-in block 5 is fixedly connected to one side of the baffle 6, a fan 9 is fixedly connected inside the ventilation main body 1, a connecting rod 10 is rotatably connected to the rear of the ventilation main body 1, a rotating disk 11 is fixedly connected to the outside of the connecting rod 10, a limiting groove 13 is opened on the rear side of the ventilation main body 1, a mounting groove 14 is opened on the rear side of the ventilation main body 1, a limiting block 23 is fixedly connected inside the limiting groove 13, and an adjusting mechanism is arranged at the rear of the ventilation main body 1, and the adjusting mechanism is used to adjust the ventilation flow rate of the rotating disk 11.

[0035] Specifically, when performing the replacement operation of the filter 2, first pull the handle 4 to cause the mounting ring 3 to rotate inside it, which then drives the thin rope 8 to rotate, drives the plug-in block 5 to move, and causes the baffle 6 to move accordingly. In this way, the spring 7 will automatically take effect until the plug-in block 5 completely withdraws from the filter 2. At this point, the removal process of the filter 2 is completed. For the installation of the new filter 2, first ensure that it is aligned with the slot 25 in the ventilation body 1. Then release the handle 4, and under the action of the spring 7, the baffle 6 and the plug-in block 5 will move automatically. At the same time, the thin rope 8 drives the mounting ring 3 to rotate to the initial position until the plug-in block 5 is firmly embedded in the filter 2. At this point, the installation process of the new filter 2 is successfully completed.

[0036] Reference Figure 5 - Figure 7The adjusting mechanism includes a motor 15, a rack 22 and a gear 12. One side of the motor 15 is fixedly connected to the inner top wall of the ventilation main body 1, one side of the rack 22 is slidably connected to the inner wall of the limiting groove 13, the gear 12 is fixedly connected to the outside of the connecting rod 10, the output end of the motor 15 is fixedly connected to a worm 16, the rack 22 is meshingly connected to the gear 12, a protrusion 24 is fixedly connected to the lower side of one end of the rack 22, the other end of the rack 22 is fixedly connected to a hollow shell 21, a connecting rod 20 is slidably connected inside the hollow shell 21, one end of the connecting rod 20 is fixedly connected to a turntable 19, a connecting shaft 18 is fixedly connected to the middle part of one side of the turntable 19, one end of the connecting shaft 18 is fixedly connected to a worm wheel 17, and the worm wheel 17 is meshingly connected to the worm 16.

[0037] Specifically, when adjusting the wind speed and flow rate, first start the drive motor 15, which will drive the worm 16 to start rotating. As the worm 16 rotates, the worm wheel 17 also moves in conjunction. Then, the worm wheel 17 drives the connecting shaft 18 to rotate, and this series of actions causes the turntable 19 to rotate. The movement of the turntable 19 further causes the connecting rod 20 to rotate and slide inside the hollow shell 21, thereby realizing the movement of the hollow shell 21 in the mounting groove 14. This movement then controls the rack 22 to move in the limit groove 13. As the rack 22 moves, the gear 12 is driven to rotate. The rotation of the gear 12 acts on the connecting rod 10, causing it to rotate as well. Finally, this rotation is transmitted to the rotating disk 11 until the ideal wind speed and flow rate adjustment position is reached.

[0038] Reference Figure 1 , Figure 5 and Figure 7 A handle 4 is fixedly connected to the outside of the mounting ring 3, one end of the thin rope 8 is fixedly connected to one side of the mounting ring 3, the other end of the thin rope 8 is fixedly connected to one side of the baffle 6, one end of the spring 7 is fixedly connected to one side of the baffle 6, the other end of the spring 7 is fixedly connected to the inner wall of the ventilation body 1, the plug-in block 5 is plugged into the spring 7, the outer side of the hollow shell 21 is slidably connected to the inside of the mounting groove 14, the outer side of the baffle 6 is slidably connected to the inside of the card slot 25, and the outer side of the plug-in block 5 is slidably connected to the inside of the card slot 25.

[0039] Specifically, a handle 4 for easy operation is provided on the outside of the mounting ring 3, one end of the thin rope 8 is fixed to one side of the mounting ring 3, and the other end is connected to the baffle 6. One end of the spring 7 is fixed to the baffle 6, and the other end is embedded in the inner wall of the ventilation body 1 to form an elastic support structure. The plug-in block 5 is designed to be plugged into the inside of the spring 7, which can not only maintain the stability of the filter 2, but also achieve smooth disassembly and assembly. The hollow shell 21 is installed in the mounting groove 14 on the outside through a sliding connection. This design allows the shell to move when necessary to cooperate with the operation of other components. Similarly, the baffle 6 is also located inside the slot 25 through a sliding connection, driving the plug-in block 5 inside the slot 25.

[0040] Working principle: When in use, the internal power supply of the fan 9 is driven to make it work. When the wind speed and flow rate need to be adjusted, the motor 15 is driven at this time, which in turn drives the worm 16 to rotate, so that the worm wheel 17 rotates, and then drives the connecting shaft 18 to rotate, so that the turntable 19 rotates, and then drives the connecting rod 20 to rotate, so that the connecting rod 20 slides inside the hollow shell 21, and then drives the hollow shell 21 to slide inside the installation groove 14, and then drives the rack 22 to move inside the limit groove 13, and then drives the gear 12 to rotate, and then drives the connecting rod 10 to rotate, and then drives the rotating disk 11 to rotate. When it is adjusted to the appropriate position, stop. Drive motor 15. When the filter 2 needs to be replaced, pull the handle 4 to make the mounting ring 3 rotate inside the mounting ring 3, and then pull the thin rope 8 to rotate, thereby driving the plug-in block 5 to move, so that the baffle 6 moves, and then the spring 7, until the plug-in block 5 completely leaves the inside of the filter 2. At this time, the disassembly is completed. When a new filter 2 needs to be installed, align the filter 2 with the slot 25 inside the ventilation body 1. At this time, release the handle 4. Under the action of the spring 7, the baffle 6 and the plug-in block 5 are driven to move. At the same time, the thin rope 8 pulls the mounting ring 3 to rotate and reset until the plug-in block 5 is reinserted into the filter 2. At this time, the installation is completed.

[0041] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
