Specifically, referring to fig. 1 to 7 of the present invention, the vacuum cleaner attachment includes a wind-controlled elbow 1 and a brush assembly 2 fitted over an outer surface of the wind-controlled elbow 1. But be provided with slide mechanism between brush subassembly 2 and the wind accuse return bend 1, slide mechanism is including setting up sand grip 3 on the inboard of brush subassembly 2 and setting up the bar groove 4 on the outside of wind accuse return bend 1, and sand grip 3 on the inboard of brush subassembly 2 matches with bar groove 4 on the outside of wind accuse return bend 1. In addition, fig. 1 also shows a wind-control slider 10 and a slider sealing cotton 11 arranged on the wind-control elbow 1.

In the embodiment shown in fig. 1-7, the number of slidable means is four, i.e. 4 strip-shaped grooves 4 are provided on the outer side of the

wind control elbow

1 and 4 ribs 3 are provided on the inner side of the brush assembly 2. However, the number of the slidable mechanisms is not particularly limited, and in order to ensure that the brush assembly 2 can slide on the wind control bend 1 better, at least two slidable mechanisms are generally provided, for example, when two slidable mechanisms are provided, the two slidable mechanisms can be symmetrically arranged in the circumferential direction of the wind control bend 1 and the brush assembly 2.

Further alternatively, the slidable mechanism may also comprise a strip-shaped groove provided on the inner side of the brush assembly 2, which matches with a rib on the outer side of the wind control elbow 1, and a rib provided on the outer side of the wind control elbow 1. It will be appreciated that the particular construction and arrangement of the vacuum cleaner attachment with such a slidable mechanism is equally possible as described below and will therefore not be described in further detail.

As shown in fig. 1 and 2, a fixing mechanism is further disposed between the brush assembly 2 and the wind control elbow 1, and the fixing mechanism includes a boss 5 disposed on the inner side of the brush assembly 2, a button 6 for releasing the boss 5 disposed on the outer side of the brush assembly 2, and

grooves

7 and 8 disposed at the front end and the rear end of the outer side of the wind control elbow 1, respectively, and matched with the boss 5.

The brush assembly 2 has two working states and a non-working state, and in the non-working state, as shown in fig. 3A, the boss 5 is fixed in the groove 8 at the rear end of the wind control elbow 1, and at the moment, the whole brush assembly 2 is retracted to the rear of the front end part of the wind control elbow 1; when the brush assembly 2 needs to be switched to the working state, the button 6 is pressed to release the boss 5 from the groove 8 at the rear end of the wind control elbow 1, so that the brush assembly 1 is moved to the front end of the wind control elbow 1 to fix the boss 5 in the groove 7 at the front end of the wind control elbow 1, as shown in fig. 3B, at least part of the brush assembly 2 extends to the front of the front end of the wind control elbow 1.

In a specific embodiment, the number of the fixing means may be one, or preferably two, as shown in fig. 4 and 5, which shows two pressing fixing means symmetrically arranged at both sides of the wind control elbow 1 and the brush assembly 2 (each fixing means includes a boss 5 and a button 6 arranged on the brush assembly 2 and

grooves

7 and 8 at the front and rear ends of the wind control elbow 1). So that the sliding and fixing of the brush assembly 2 on the wind control elbow 1 can be achieved by pressing the buttons 6 at both sides.

In the case where two fixing mechanisms are arranged, four slidable mechanisms may be provided, and the four slidable mechanisms are arranged on both sides of the two fixing mechanisms, respectively. For example, referring to fig. 6 and 7, four strip grooves 4 are arranged on the outer side of the wind control elbow 1, correspondingly, four protruding strips 3 corresponding to the four strip grooves are provided on the inner side of the brush assembly 2, wherein every two strip grooves 4 (i.e., slidable mechanisms) are respectively arranged on both sides of the front and rear end grooves 7 and 8 (i.e., fixing mechanisms) of the wind control elbow 1, and every two protruding strips 3 (i.e., slidable mechanisms) are arranged on both sides of the boss 5 (i.e., fixing mechanisms).

As for the boss 5 provided on the inner side of the brush assembly 2, the shape thereof is not limited, for example, it may be circular, triangular, etc., and preferably, the boss 5 is a square boss as shown in fig. 2, and correspondingly, the

grooves

7 and 8 disposed at the front and rear ends of the wind-control elbow 1 are square grooves to match the square boss.

In a further embodiment, a limiting rib may be provided on the outer surface of the rear portion of the wind-control elbow 1 for limiting the sliding of the brush assembly 2 when the wind-control elbow is in the non-operating state. The specific arrangement position of the limiting rib is not particularly limited, and the brush component 2 in the non-working state can be limited by sliding. For example, in fig. 6, a stopper rib 9 may be provided at the rear of the strip groove 4 on the outer side of the wind control elbow 1. The specific number of the limiting ribs is not limited, for example, one limiting rib 9 may be respectively arranged at the rear part of each strip-shaped groove 4. Similarly, in the case where a convex strip is provided on the outer side of the wind control elbow 1 and a bar-shaped groove is provided on the inner side of the brush assembly 2, the stopper rib 9 may be disposed at the rear of the convex strip on the outer side of the wind control elbow 1.
