[0002] With the continuous development of modern industrial technology and the improvement of people's living standards, the requirements for air quality are also increasing. Especially in certain specific environments, such as laboratories, hospital operating rooms, electronic factories and other places with high dust-free or clean requirements, the application of dust-free air supply devices has become particularly important. These places need to maintain extremely high air cleanliness to ensure product quality, reduce pollution risks or ensure personnel health.

[0003] Traditional air supply devices usually have problems such as uneven air supply and poor air filtration effect, which directly affects the stability and air quality of the dust-free environment. Especially during the air supply process, due to the uneven distribution of air flow and the limitation of filtration efficiency, dust and other impurities may enter the dust-free environment through the air supply device, thus threatening the cleanliness of the environment.

[0004] Therefore, it is necessary to design a new type of dust-free air supply device, which needs to have the characteristics of efficient filtration, uniform air supply, and stable and reliable. By introducing the combined design of air supply channel, fan, filter layer and protective shell, the problems existing in traditional air supply devices can be effectively solved and the air quality and stability of dust-free environment can be improved.

[0028] In the embodiment of the utility model, this case provides a dust-free air supply device, including an air supply channel 130, a fan 120, a filter layer 110, and a protective shell 100. The protective shell 100 is composed of an upper shell 101, a middle shell 102, and a lower shell 103, which are connected in sequence up and down, and the three are interconnected. The upper shell 101 is provided with a filter layer 110 for filtering impurities, and the middle shell 102 is provided with a uniform layer 140 for uniform air supply. The lower shell 103 is connected to the air supply channel 130, and a fan 120 is connected to the air supply channel 130. The fan 120 sucks the airflow from the inlet end of the protective shell 100 and flows out from the outlet end of the air supply channel 130.

[0029] Specifically, 1. The design of the filter layer 110 in the device can effectively filter dust and other impurities in the air entering the dust-free environment. This is crucial to maintaining a high degree of cleanliness in the dust-free environment, and can significantly reduce the risk of dust to product quality, personnel health and environmental pollution. 2. The uniform layer 140 set in the middle shell 102 can achieve uniform distribution of airflow through its specific structural design. This ensures that the air supply device provides uniform and stable airflow in the entire dust-free environment, avoids problems such as temperature fluctuations and dust accumulation caused by uneven airflow, thereby improving the overall stability of the dust-free environment. 3. The upper shell 101, the middle shell 102 and the lower shell 103 are connected in sequence up and down, which not only ensures the overall structural stability of the device, but also makes the maintenance of the device more convenient. In addition, the design of the protective shell 100 also helps to reduce the interference of external factors on the internal components of the device, and improves the durability and reliability of the device. The wind flow flows in from the open end of the upper shell 101 under the influence of the fan 120, passes through the filter layer 110 and other mechanisms in turn, and completes the dust-free air supply function.

[0030] In another embodiment of the utility model, the upper end of the upper shell 101 is open, and the upper edge extends a limit portion 200 toward the center end, and the filter layer 110 is located in the limit portion 200. Specifically, the limit portion 200 is provided to prevent the filter layer 110 from being separated from the protective shell 100, and the wind flow flows in from the open end of the upper shell 101 under the influence of the fan 120, passes through the filter layer 110 and other mechanisms in sequence, and completes the dust-free air supply function.

[0031] In another embodiment of the utility model, the outer side wall of the uniform layer 140 extends outward to form an abutment end 210, and the abutment end 210 is limitedly connected to the inner edge side of the middle shell 102. The uniform layer 140 has a honeycomb structure and is used to guide the airflow. Specifically, the abutment end 210 is stuck on the inner edge side of the middle shell 102 so that it is not easy to fall off. The uniform layer 140 is similar to the shape of a honeycomb, and each small room helps to guide and disperse the airflow.

[0032] In another embodiment of the utility model, a reinforcing rib 220 is provided on the outer side wall of the middle shell 102 for enhancing connectivity.

[0033] In another embodiment of the utility model, a protruding layer 230 for limiting is extended from the top of the lower shell 103 toward the center end, and the upper end diameter of the lower shell 103 is larger than the lower end diameter. The protruding layer 230 prevents the middle shell 102 from collapsing downward, and the upper end diameter of the lower shell 103 is larger than the lower end diameter, which can form an airflow concentration effect and enhance the conduction of the fan 120.

[0034] In another embodiment of the utility model, the upper shell 101, the middle shell 102 and the lower shell 103 are threadedly connected.

[0035] In another embodiment of the utility model, a support frame 240 is disposed on the outer side of the air supply channel 130 for enhancing stability.

[0036] In another embodiment of the utility model, the filter layer 110 is made of fiber filter material. The most common filter material of fiber filter material is made of synthetic fiber (such as polyester, polypropylene) or glass fiber. The gaps formed between the fibers can capture particulate matter.

[0037] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
