Specifically, each surface of the protective grid 24 is formed as a curved surface with a rounded transition between any two adjacent surfaces. Therefore, the wind resistance can be further reduced, the flow speed of the air flow can be ensured, and the dust collection effect of the dust collector 100 can be improved.

According to some embodiments of the present invention, a plurality of ribs 217 are disposed on the inner bottom wall of the lower housing 2, and the plurality of ribs 217 are radially distributed around the first dust suction port 213. For example, the lower housing 2 includes the bottom housing 21, the inner bottom wall of the bottom housing 21 is provided with a plurality of ribs 217 and a first dust suction port 213, the first dust suction port 213 is located at a middle position of the inner bottom wall of the bottom housing 21, the plurality of ribs 217 are disposed at an outer periphery of the first dust suction port 213 and are radially arranged with the first dust suction port 213 as a center, and one of the protrusions 218 is provided between two adjacent ribs 217. Therefore, the arrangement of the plurality of reinforcing ribs 217 is beneficial to improving the structural strength of the lower shell 2 and prolonging the service life of the lower shell 2.

According to some embodiments of the present invention, an installation space 111 for installing the driving motor 5 and the battery 4 is defined between the upper case 11 and the middle case 12. For example, as shown in fig. 3, the upper casing 11 has an installation space 111 with an open bottom, the middle casing 12 is disposed on an open side of the installation space 111 to cover the installation space 111, the lower casing 2 is disposed below the middle casing 12 and connected to the middle casing 12, an open top side of the lower casing 2 is covered by the middle casing 12, the installation space 111 is used for installing the driving motor 5 and the battery 4, the battery 4 is used for supplying power to the driving motor 5, and the accommodating space 212 of the lower casing 2 is used for installing the filter member 3 and the movable impeller 6, wherein a motor shaft of the driving motor 5 penetrates through the middle casing 12 and extends from the installation space 111 into the accommodating space 212 to be connected to the movable impeller 6 to drive the movable impeller 6 to rotate, and the rotation of the movable impeller 6 can drive the flow of the air current. Therefore, the structure layout is more reasonable, and the miniaturization design of the dust collector 100 is more favorably realized.

The specific structure and operation of the driving motor 5, the movable impeller 6, the filter member 3, the battery 4, etc. are well known to those skilled in the art, and will not be described in detail herein.
