Description

Technical Field

[0001] This invention relates to the field of indoor air purification technology, and more particularly to a fresh air device for indoor air conditioning. Background Technology

[0002] A fresh air system is an effective air purification device that circulates indoor air. On the one hand, it expels polluted indoor air to the outside, and on the other hand, it introduces fresh outdoor air into the room after sterilization, disinfection, and filtration, ensuring that the room is always filled with fresh and clean air. Utilizing patented fresh air convection technology, the fresh air system achieves air convection through autonomous air supply and exhaust, maximizing indoor air exchange. Its built-in multi-functional purification system ensures clean and healthy air entering the room. Fresh air systems are mainly divided into two types: exhaust-type and supply-type. They can be installed in most indoor environments, are easy to install, and comfortable to use. A fresh air system is a healthy companion for home life. In 1935, Robert Chun invented and manufactured the world's first heat exchange device for filtering air pollution, also known as a "fresh air system."

[0003] While existing fresh air systems can effectively circulate and exchange heat in indoor air, the ductwork is often integrated into a single unit and is generally quite long. This makes modular assembly of the ductwork ineffective, requiring the entire duct to be disassembled and replaced if a fault occurs, increasing operating costs. Furthermore, without power, the ductwork is not effectively cleaned of dust adhering to its inner walls during ventilation, leading to dust buildup and blockages, resulting in decreased air quality and reduced air freshness.

[0017] Preferably, the inside of the cooling liquid storage box stores fluorinated liquid cooling medium, and the conveying pipe and the motor body are one-to-one corresponding.

[0018] Beneficial effects:

[0019] While existing fresh air systems can effectively circulate and heat indoor air, the ductwork is often integrated into a single unit, resulting in relatively long ducts. This makes modular assembly of the ductwork ineffective, requiring complete disassembly and replacement of the entire duct when a malfunction occurs, increasing operating costs. Furthermore, the lack of power in scraping away dust adhering to the duct's inner walls during ventilation is insufficient, leading to dust buildup and blockage over time. This deteriorates airflow quality and reduces air freshness.

[0020] 1. In use, this invention aims to improve the simultaneous cleaning of dust from the inner wall of the duct without power. When air flows, the first fan blade, with its central axis perpendicular to the central axis of the first duct, rotates without power, driving a bevel gear set to rotate. The rotation of the bevel gear set, through the rotation of the rotating shaft, drives a spiral rod to rotate. The spiral rod alters the airflow characteristics, accelerating the air and impacting the baffle. A spring connects to the telescopic rod, causing it to extend and retract, removing the connecting block from the vent. The rotating pull rod then lowers the lifting plate along the cleaning opening, disengaging it. The continuous sliding scraping of the baffle discharges dust from the cleaning opening, achieving simultaneous cleaning of dust inside the duct.

[0021] 2. In order to prevent backflow during ventilation of the fresh air equipment, when the air pressure at the vent is lower than that on the other side, the connecting block fixedly connected to the baffle will retract under the reaction force of the spring being squeezed, so that the connecting block is inserted into the vent, thereby achieving the effect of convenient and automatic sealing of the inner cavity of the air duct and reducing the effect of airflow recirculation.

[0022] 3. In use, to improve the modular assembly effect between air ducts, the second air duct is inserted into the connecting frame at the end of the first air duct, so that the positioning groove contacts the connecting groove and the positioning ring is embedded in the positioning groove. The air pump is turned on, so that the air bag inflates in the positioning ring and pressurizes the positioning ring in the positioning groove, thereby achieving the effect of secondary fixation of the positioning ring in the positioning groove and improving the stability of the modular assembly between air ducts.

[0023] 4. The application in use, in order to reduce the heat of the motor under the continuous rotation, improve the service life of the motor under long time operation, open the extraction pump of the outer wall of the conveying pipe, the cooling medium in the cooling liquid storage box is conveyed to the rotary joint through the conveying pipe, and under the action of the cooling cavity, the cooling medium carries out the heat absorption operation to the surface of the suction fan blade, reduces the heat load of the motor under long time operation, and improves the service life of the motor under long time operation.
