Referring to fig. 4 and 6, trigger mount 80 illustratively includes a transverse wall 82, and first and second upstanding walls 83, 84 extending from transverse wall 82 in a direction away from transverse wall 82. The first standing wall 83 and the second standing wall 84 have a gap in the longitudinal direction of the lateral wall 82, i.e., the front-rear direction QH described above. Through holes 85 are formed in the first standing wall 83 and the second standing wall 84, respectively, and the trigger 30 can be inserted through the through holes 85 of the first standing wall 83 and the second standing wall 84 in sequence.

The end 31 of the trigger 30 located in the housing 20 may abut against the top plate 15, and exert a force on the top plate 15, thereby triggering the rotation of the front cover 10.

In order to prevent the trigger 30 from separating from the trigger mounting seat 80, as a possible embodiment, a stopping portion 86 is further disposed between two ends of the trigger 30, when the trigger 30 is inserted into the through hole 85 of the first standing wall 83 and the second standing wall 84, the stopping portion 86 may be stopped inside the first standing wall 83, and an outer edge contour dimension of the stopping portion 86 is larger than an inner edge dimension of the through hole 85 on the first standing wall 83, so as to prevent the trigger 30 from falling out of the through hole 85 of the first standing wall 83.

In other examples, a through hole may be formed in the trigger mounting seat 80, the through hole extends along the front-rear direction QH, and the through hole may form the guide channel 81.

In the embodiment of the present application, the trigger mounting seat 80 may further be provided with an elastic member 16, such as a compression spring, and the elastic member 16 abuts between the trigger mounting seat 80 and a portion of the trigger 30 facing the outside of the housing 20 and applies an elastic force to the trigger 30 facing the outside of the housing 20. Specifically, the elastic member 16 abuts between the second standing wall 84 and the stopping portion 86 of the trigger 30, so that after the cleaning of the wall corner and other positions is finished, the elastic force of the elastic member 16 can return the trigger 30 to the original position, that is, the elastic member 16 can perform the resetting function.

For example, referring to fig. 6, in order to fix the trigger mounting seat 80 to the housing 20, a fixing seat 91 is further provided inside the housing 20, and the trigger mounting seat 80 is provided inside the housing 20 by being connected to the fixing seat 91. For example, the trigger mounting seat 80 is provided with mounting portions 92 at positions corresponding to the fixing seats 91, and the mounting portions 92 are connected to the fixing seats 91 in a one-to-one correspondence.

In the embodiment of the present application, referring to fig. 5, the trigger mounting seats 80 may be located on both sides of both end portions of the front end cover 10 in the length direction L. Note that the longitudinal direction L of the front cover 10 here may be perpendicular to the front-rear direction QH. Thus, the thickness of the dust collector floor brush 100 can be reduced, and on the other hand, the dust collector floor brush can also be suitable for the condition that the height of a surface to be cleaned in the vertical direction such as a step is lower.

In the present embodiment, referring to fig. 1, an end of the trigger 30 facing the front side Q of the housing 20 protrudes outside the other portion of the cleaner brush 100. Thus, when the user uses the vacuum cleaner 100 and the front side of the floor brush is about to touch the vertical wall of the corner, the vertical wall can contact and press against the trigger 30 before the trigger 30, so that the trigger 30 triggers the front cover 10 to rotate to open the first opening region 61.

Specifically, the housing 20 may further include an auxiliary covering portion 17 at the front end, the auxiliary covering portion 17 covers the front side Q of the trigger mounting seat 80, and the trigger 30 is exposed outside the housing 20 through the auxiliary covering portion 17, in other words, an end portion of the trigger 30 facing the front side Q of the housing 20 protrudes from the first standing wall 83 and the auxiliary covering portion 17.

In the embodiment of the present application, a rolling brush (not shown) is further provided in the housing, the rolling brush is located at a position corresponding to the first opening region 61, and the horizontal cross section of the trigger 30 is located in the same plane as the horizontal cross section of the rolling brush. Thus, when the first opening region 61 abuts against the vertical wall of the corner, the front cover can be maximally opened.

Referring to fig. 3b, 5, in one possible embodiment, the rotation axis of the front cover 10 is located inside the housing 20 and at a position spaced from the first opening region 61, so that the cover main body 11 can be rotated into the first opening region 61 or away from the first opening region 61. By locating the rotation axis of the front cover 10 inside the housing 20 in this manner, interference with the edge of the first opening region 61 when the cover main body 11 rotates can be avoided.

Referring to fig. 2 and 3b, for example, the front cover 10 may include at least one rotating column 12 fixed to the cover main body 11, a hinge seat 23 corresponding to the rotating column 12 is provided in the housing 20, and the front cover 10 is hinged to the corresponding hinge seat 23 through the rotating column 12. Specifically, the number of the rotating columns 12 is two, and the number of the hinge bases 23 is two. The rotation posts 12 may be located at both sides in the longitudinal direction of the cover main body 11. Here, the front cover 10 is hinged to a hinge seat 23 provided inside the housing 20, and the rotation of the front cover 10 can be controlled by the position of the hinge seat 23.

Referring to fig. 3b, the top plate 15 may be connected to the rotary post 12, and the top plate 15 is parallel to the axis O of the rotary post 12, which is the axis of rotation of the front cover 10 of the rotary post 12. Thus, the extension line of the top plate 15 passes through the rotation axis of the front cover 10, and the trigger 30 can trigger the rotation of the front cover 10 with a smaller pushing force than when the top plate 15 is disposed at another position.

Illustratively, the front cover 10 further includes a connecting portion 13, the connecting portion 13 extends from the cover body 11 in a direction away from the cover body 11, and an end of the connecting portion 13 is connected to the rotation column 12. The cover body 11 and the rotary post 12 are connected by a connecting portion 13. The connecting portion 13 may be formed as a plate-like member.

In a possible implementation, the top plate 15 is also connected to the connection 13. As described above, the top plate 15 is connected to both the connecting portion 13 and the rotary post 12, so that the connection strength between the connecting portion 13 and the rotary post 12 can be reinforced.
