The first lead-out surface 621 is connected to the inner ring 612, and the second lead-out surface 622 is connected to the outer ring 613. First lead-out surface 621 extends from inner race 612 substantially in a tangential direction of inner race 612 and second lead-out surface 622 extends from outer race 613 substantially in a tangential direction of outer race 613. The lead-out bottom surface 623 connects the first lead-out surface 621 and the second lead-out surface 622, and the lead-out bottom surface 623 is also connected to the bottom surface 614 of the vortex portion 61.
The stopper 63 includes: a stop surface 631 and a connection surface 632. The stop surface 631 is used to stop the air flow flowing in the vortex portion 61, so that the air flow flows out of the outlet portion 62. The lead-out portion 62 is located substantially on a first side of the first plane 501. It is understood that, in the present embodiment, 90% or more of the lead-out portion 62 is located on the first side of the first plane 501, and the lead-out portion 62 can be considered to be located substantially on the first side of the first plane 501. The stop surface 631 is also located on the first side of the first plane 501, i.e. the stop surface 631 and the lead-out 62 are located on the same side of the first plane 501. Alternatively, in other embodiments, the stop surface 631 and a portion of the lead-out 62 are located on the same side of the first plane 501. Alternatively, in other embodiments, at least a portion of the stop surface 631 and at least a portion of the lead-out 62 are on the same side of the first plane 501.
The stopper 63 is disposed at the edge of the lead-out portion 62. Specifically, a stop surface 631 is disposed at the first lead-out surface 621, the stop surface 631 extending from the inner ring 612 to the outer ring 613. The stop surface 631 also extends from the bottom surface 614 in a direction away from the bottom surface 614, i.e., one side of the stop surface 631 connects to the connection of the bottom surface 614 and the first lead-out surface 621. A connecting surface 632 extends from the side of the stop surface 631 remote from the bottom surface 614 along a plane obliquely intersecting the stop surface 631, the connecting surface 632 connecting the stop surface 631 and the bottom surface 614.
In the present embodiment, the stopper 63 is integrally formed with the vortex portion 61, and the vortex portion 61 is recessed toward the ground to form the stopper 63. The stopper 63 is located inside the vortex portion 61, the stopper 63 is also located inside the vortex passage 611 formed by the vortex portion 61, and the stopper 63 is also located on the vortex flow path 60 b.
The stop 63 and the lead-out 62 are also arranged on the same side of a second plane 505 passing through the first axis 504 and perpendicular to the first plane 501. That is, the stopper 63 and the lead-out portion 62 are provided at the rear of the chassis 60.
In a direction perpendicular to the first plane 501, at least a part of the stopper 63 is also located between the lead-out portion 62 and the hole 641.
The ratio of the dimension L1 of the stopper 63 in the direction of the first axis 504 to the depth L2 of the vortex portion 61 in the direction of the first axis 504 is 0.1 or more and 0.5 or less, so that it is possible to prevent the stopper 63 from being too large in size and thus the vortex portion 61 from being unable to generate an effective vortex, and to prevent the stopper 63 from being too small and thus the guide-out efficiency of the guide-out portion 62 and the grass cutting capability of the lawnmower 500 from being affected.
