In addition, the second limiting groove 121 can generate a certain blocking effect on the first absorbing member 130 and the second absorbing member 150, so as to prevent the second absorbing member 150 from moving along with the first absorbing member 130 and separating from the rear fan housing 120 in the process of separating the front fan housing 110 and the rear fan housing 120 from each other.

In this embodiment, the cross-sectional shapes of the second limiting groove 121 and the second absorbing member 150 are all circular. Of course, in other embodiments of the present utility model, the cross-sectional shapes of the second limiting groove 121 and the second absorbing member 150 may be rectangular, triangular, diamond-shaped, etc., and the specific shape thereof is not limited.

Referring to fig. 1 and 6, the fan housing structure 100 further includes an elastic clamping member 140, the elastic clamping member 140 is disposed on the front fan housing 110, and the rear fan housing 120 is provided with a locking hole 123 in a locking fit with the elastic clamping member 140.

In the above-mentioned solution, the spring 141 is configured to support the pressing portion 1421 and the locking portion 1423 on the locking block 142 at the same time, so that the locking portion 1423 can pass through the locking hole 123 under the supporting force of the spring 141, thereby realizing the locking effect on the front fan housing 110 and the rear fan housing 120. When the pressing portion 1421 is pressed by an external force to press the spring 141, the locking portion 1423 is driven to disengage from the locking hole 123, so as to unlock the front fan housing 110 and the rear fan housing 120, and facilitate the relative rotation of the two.

It should be noted that the toggle protrusion 113 is provided with a cavity, and a portion of the elastic clip 140 is accommodated in the cavity.

The specific working principle of the fan housing structure 100 is as follows:

when the front fan housing 110 and the rear fan housing 120 are required to be disassembled, a worker presses the pressing part 1421 to press the spring 141, so that the locking part 1423 is separated from the locking hole 123, and the front fan housing 110 and the rear fan housing are unlocked; and the front fan housing 110 is driven to rotate relative to the rear fan housing 120 by stirring the convex blocks 113, the locking convex blocks 122 and the buckling grooves 112 which can be matched in a clamping manner are used as fulcrums during rotation, and the adsorption acting force between the first adsorption block and the second adsorption block needs to be overcome, so that the front fan housing 110 and the rear fan housing 120 are rapidly separated, and the fan housing structure 100 is convenient to clean.

When the front fan housing 110 and the rear fan housing 120 are required to be installed, the front fan housing 110 and the rear fan housing 120 are positioned through the locking protruding blocks 122 and the buckling grooves 112, the front fan housing 110 is driven to rotate relative to the rear fan housing 120 by pulling the protruding blocks 113 by taking the locking protruding blocks 122 and the buckling grooves 112 which are matched in a clamping manner as supporting points, and when the front fan housing 110 and the rear fan housing 120 are relatively close to each other, the first absorbing member 130 and the second absorbing member 150 generate absorption acting force, so that the front fan housing 110 is tightly attached to the rear fan housing 120 to be fixed. In addition, the pressing portion 1421 needs to be pressed before the front and rear hoods 110 and 120 are completely attached to each other, the spring 141 is pressed, interference between the locking portion 1423 and the rear hood 120 is avoided from being generated in advance until the locking portion 1423 moves to a position corresponding to the locking hole 123, the pressing portion 1421 is released, and the locking portion 1423 extends into the locking hole 123 due to the reset action of the spring 141, so that the front and rear hoods 110 and 120 are connected in a snap-fit manner.
