It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present utility model. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0023] In the description of the content of the present utility model, it should be noted that unless otherwise clearly specified and defined, terms such as "installation", "provided with", "connection", etc. shall be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the content of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figures 1-4 , an embodiment provided by the content of the present utility model: a ventilation and air exchange device for architectural design, including a fixing plate 1 and a ventilation mechanism 3. A housing 2 is provided behind the fixing plate 1, a ventilation mechanism 3 is provided inside the housing 2, an inner sleeve 301 is provided inside the housing 2, a motor 304 is provided inside the inner sleeve 301, a smoke detector 307 is provided behind the motor 304, a second handle 310 is provided on the side of the inner sleeve 301, and a draw plate 311 is provided inside the second handle 310.

[0026] Specifically, the inner sleeve 301 and the housing 2 are of a sliding structure. A first handle 302 is provided at the front end of the inner sleeve 301. First, the housing 2 needs to be fixed to the wall through the fixing plate 1. The inner sleeve 301 can be pulled out of the housing 2 through the first handle 302 for internal maintenance and cleaning without the disassembly of nuts, which is convenient and fast.

[0027] Specifically, a shutter 303 is provided above the first handle 302. The shutter 303 is connected to the inner sleeve 301 by screws. The material of the shutter 303 is aluminum alloy. The design of the shutter 303 prevents sundries from entering the interior of the device during ventilation and causing damage to the fan. The aluminum alloy material has a relatively high hardness and a relatively light mass, which is convenient for disassembly.

[0028] Specifically, the motor 304 is a bidirectional motor. A rotating rod 305 is threadedly connected to the front end of the motor 304, and a fan blade 306 is threadedly connected to the front end of the rotating rod 305. The fan blade 306 is made of stainless steel. When the motor 304 rotates, it drives the rotating rod 305 and then drives the rotation of the fan blade 306, which can achieve a ventilation effect. After the bidirectional motor 304 sucks outdoor air into the room, a pressure difference is formed, and the turbid air in the room is discharged through other windows or doors, achieving a fresh air effect. When discharging the indoor air outdoors, it can quickly extract smoke or waste gas.

[0029] Specifically, an alarm 308 is provided on the surface of the smoke detector 307. The top end of the motor 304 is electrically connected to a processor 309, and the processor 309 is electrically connected to the smoke detector 307. When a fire breaks out or there is a large amount of smoke in the room, the smoke detector 307 detects smoke particles, transmits a signal to the processor 309, and at the same time, the alarm 308 sounds. The processor 309 controls the motor 304 to reverse, quickly discharging the indoor smoke. Such a design is used in the fire mode to help disperse the smoke, provide a smoke-free environment for personnel evacuation, and protect personal and property safety.

[0030] Specifically, the draw plate 311 is connected to the inner sleeve 301 by a card slot. A card slot is provided inside the draw plate 311. A first filter screen 312 is provided inside the draw plate 311. A plastic card block 313 made of rubber is provided on the outer side of the first filter screen 312. The first filter screen 312 is connected to the draw plate 311 by the plastic card block 313 to form a card slot connection. The filter screen can be quickly drawn out through the draw plate 311 for cleaning and replacement without complex disassembly of the device. At the same time, the plastic card block 313 made of rubber.

[0031] Specifically, a second filter screen 314 is provided behind the first filter screen 312, and a third filter screen 315 is provided behind the second filter screen 314. The mesh sizes of the three groups of filter screens are different, enabling multi-level screening and separate drawing and cleaning. Users do not need to disassemble the entire system to clean each part. The modular processing has stronger flexibility and increases the service life of the device at the same time.

[0032] Working principle: Connect the fixed plate 1 to the wall through bolts, insert the outer shell 2 into the wall to connect the indoor and outdoor channels, connect the first filter screen 312 to the pull-out plate 311 through plastic blocks 313 and insert it into the side of the inner sleeve 301. Insert the second filter screen 314 and the third filter screen 315 into the inner sleeve 301 as well. Place the inner sleeve 301 inside the outer shell 2. The motor 304 rotates to drive the rotating rod 305, which in turn drives the rotation of the fan blades 306 to ventilate the room. When a fire occurs, the smoke detector 307 detects smoke particles, transmits a signal to the processor 309, and at the same time, the alarm 308 sounds. The processor 309 controls the motor 304 to reverse. When the equipment needs to be cleaned, pull out the inner sleeve 301 through the first handle 302 and pull out the pull-out plate 311 through the second handle 310 to clean and replace the filter screen.

[0033] The above are only embodiments of the content of the present utility model. Specific structures and common knowledge such as characteristics that are well-known in the art are not described in detail here. For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.
