Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the following description will be made in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

Referring to fig. 1 to 4, a fan housing structure of a motor of a vacuum cleaner is characterized by comprising: a cover 100 in a cylindrical shape; a cover bottom 200 extending from one end of the cover surface 100 and protruding axially to form a boss, the cover bottom 200 having a wind hole 210 in the middle; wherein, at one end of the cover face 100 back to the cover bottom 200, a plurality of grooves are annularly arrayed on the end face of the cover face 100, protrusions 113 for riveting are arranged in the grooves, a first gap 111 and a second gap 112 which are convenient for bending the protrusions 113 are arranged between the protrusions 113 and two sides of the circumferential direction of the grooves, wherein the first gap 111 is used for the fixed impeller protrusion 310 of the fixed impeller 300 to protrude, and the protrusions 113 are bent, riveted and abutted against the fixed impeller protrusion 310.

Set up recess and bump 113 to form fixedly through the mode of riveting with fixed impeller 300, increased overall structure's stability, and easy operation has replaced additional parts such as traditional bolts, has practiced thrift manufacturing cost. The first gap 111 and the second gap 112 are arranged on two sides of the salient point 113, so that the salient point 113 can be bent and riveted conveniently.

Referring to fig. 1, 3 and 4, the end of the cover 100 at the end away from the cover bottom 200 protrudes radially outward to form a convex ring 110, and the groove is disposed in the convex ring 110. The thickness of the salient points 113 and the end faces can be improved, the strength is improved, and the connection stability of the fan cover and the fixed impeller 300 is ensured.

Referring to fig. 1-4, the circumferential width of the first gap 111 is greater than the circumferential width of the second gap 112. The protrusions 113 are bent to press the stationary blade 300 so that the stationary blade 300 does not rotate in the circumferential direction.
