Description

Technical Field

[0001] The utility model relates to the technical field of machine bases, in particular to a fan machine base structure. Background Art

[0002] Fresh air purifiers are a new type of electrical appliance that continuously ionizes the air, generating a large number of negative ions. These are then transported by a fan, forming a negative ion airflow that cleanses and purifies the air, effectively improving air cleanliness and creating a more natural and comfortable environment. Fresh air purifiers have a fan inside that draws air into the purifier, filters it, and then delivers the filtered air indoors.

[0003] When the fan blades are working, a lot of dust is likely to adhere to the blades, making it easy for more bacteria to exist in the wind passing through the blades. The fan base is installed inside the fresh air purifier. When disassembling the fan, it is necessary to open the purifier first, which is inconvenient to operate.

[0004] The existing Chinese patent with announcement number CN216744723U discloses a fresh air purifier provided with a detachable fan bracket; it includes a shell and a supporting device, the supporting device includes a fan, a mounting plate, a fixing plate, a guide rail and a rubber pad, the guide rail is fixedly connected to the shell, the fixing plate is slidably connected to the guide rail, the fan is fixedly connected to the fixing plate, the mounting plate is fixedly connected to the fixing plate and is detachable from the shell, the rubber pad is fixedly connected to the mounting plate, the rubber pad is made of rubber, the rubber has elasticity, and when the mounting plate is connected to the shell, there is no gap between the connecting parts, the fan is mounted on the fixing plate through the fixing plate, the sliding connection between the guide rail and the fixing plate enables the fixing plate to drive the fan to move, and the mounting plate and the shell are detachable, so that the mounting plate can be removed from the shell, so that the fixing plate and the fan can be removed, thereby achieving the purpose of facilitating the maintenance of the fan.

[0005] In view of the above and existing related technologies, the inventors believe that the following defects often exist: the device adopts a straight channel air intake and cannot flexibly adjust the direction of the air inlet according to the use environment, and needs to be improved; therefore, a fan base structure is proposed to address the above problems.
