Detailed Description
In order to describe the technical content, constructional features, achieved objects and effects of the present application in detail, the technical solutions in the embodiments of the present application will be described below with reference to the accompanying drawings in the embodiments of the present application.
Spatially relative terms, such as "under … …," "under … …," "under … …," "lower," "above … …," "upper," "above … …," "higher," "side" (e.g., as in "sidewall") and the like, may be used herein to describe one element's relationship to another element(s) as illustrated in the figures. Spatially relative terms are intended to encompass different orientations of the device in use, operation and/or manufacture in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as "under" or "beneath" other elements or features would then be oriented "over" the other elements or features. Thus, the exemplary term "below … …" may include both upper and lower orientations. Furthermore, the device may be otherwise positioned (e.g., rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.
Fig. 1 shows a cleaning tool 100 for a vacuum cleaner provided herein, the cleaning tool 100 being adapted to clean various corners (e.g., corners, tables, etc.). The cleaning tool 100 comprises a connection pipe 1 connectable in fluid communication to a respective vacuum cleaner and a head 2 movable along a surface to be cleaned, the head 2 comprising a housing 3, a rotatable member 4 rotatable about a first axis Y1, three rotatable discs 5 contactable with the surface to be cleaned, and three suction openings 6, each suction opening 6 being located between two adjacent rotatable discs 5, respectively.
Referring to fig. 4, a housing 3 is fixedly coupled to a connection pipe 1, and a rotatable member 4 is rotatably installed to the housing 3 and positioned at a lower side of the housing 3. The rotatable part 4 has a substantially rotationally symmetrical regular triangle with the middle parts of the three sides of the triangle being concave inwards and forming three recesses 41.
The cleaning tool 100 further comprises a coupling member 42 mounted on the upper side of the housing 3, the coupling member 42 being rotatable with the rotatable member 4 about the first axis Y1. The connecting piece 42 includes a through hole (not shown) in the middle part, and three connecting ends 43 formed by protruding outwards from the outer edge of the connecting piece 42, the through hole is used for the connecting pipe 1 to pass through, and the three connecting ends 43 are uniformly distributed on a circumference with a center falling on the first symmetry axis Y1. The three connection ends 43 are respectively located right above the three corners of the rotatable member 4, and each connection end 43 is fixedly connected with the corner of the corresponding rotatable member 4 via a connecting rod (not shown) extending up and down to lock the rotatable member 4, prevent the rotatable member 4 from being separated from the housing 3, and prevent the rotatable member 4 from tilting. In other embodiments, a universal wheel capable of contacting the surface to be cleaned can be additionally arranged at the bottom of the rotatable component, so that the flexibility of the rotatable component is increased.
The three rotating disks 5 are circumferentially arranged in a rotationally symmetrical manner of 120 ° and equidistantly around the first axis Y1, i.e. the three rotating disks 5 are uniformly distributed on a circumference whose center falls on the first axis of symmetry Y1. The three rotary discs 5 are each rotatably connected to the rotatable member 4 at three apex angles about respective second axes Y2. Each rotating disc 5 is located at the lower side of the rotatable part 4, and the rotatable part 4 can drive each rotating disc 5 to rotate around the first axis Y1. Each rotary disk 5 has a portion projecting laterally outwardly in a horizontal direction with respect to the outer side edge portion of the rotatable member 4 to contact the surface of a wall, a desk or the like. The bottom and peripheral sides of the rotating disc 4 are provided with cleaning elements for wiping the surface to be cleaned, which may be bristles, wiping cloths or scraping strips. In other embodiments, the rotating disk may also be provided with cleaning members only at the bottom or peripheral sides.
Referring to fig. 1 to 3, the connection pipe 1 extends in the up-down direction and is located at a central position of the dust collection tool 100, and in this example, an axis of the connection pipe 1 coincides with the first axis Y1. The connecting tube 1 defines an outflow channel 11 for air flow from the cleaning tool 100, and the housing 3 defines an internal channel 31 in fluid communication with the outflow channel 11.
Three dust suction openings 6 are respectively arranged at the three concave parts 41 and positioned at the lower side of the rotatable part 4, one dust suction opening 6 is arranged between every two adjacent rotating discs 5, and each dust suction opening 6 can rotate along with the rotatable part 4 around the first axis Y1. Each suction opening 6 is arranged to open outwards and in fluid communication with the internal passage 31, the suction opening 6, the internal passage and the outflow passage 11 forming a fluid suction path for air to flow into and out of the suction tool 100, which fluid suction path is in fluid communication with the vacuum cleaner when the suction tool 100 is attached to the vacuum cleaner.
In other embodiments, more than three rotating discs may be provided for the cleaning tool; the rotatable members may be arranged in any geometric shape (e.g., circular or elliptical) with the proviso that each rotatable disk has a portion that is laterally and relatively convex with respect to the rotatable members, preferably the rotatable members may be configured as polygons having a number of sides consistent with the number of rotatable disks, and the polygons may further preferably be regular polygons; the dust collection tool can be additionally provided with a dust collection opening which is also in fluid communication with the internal channel at the bottom of the shell, and the dust collection opening can be used for cleaning the surface to be cleaned when the dust collection tool works.
The following describes the working principle of the dust extraction tool 100: when the cleaning tool 100 is attached to a corresponding vacuum cleaner, the fluid suction path is in fluid communication with the vacuum cleaner. When cleaning operation is performed on the corner, the dust collection tool 100 can always keep at least two rotating discs 5 attached to the wall or the surface of the desk body and the like at the corner by adjusting the angle of the rotating disc 5 and the dust collection opening 6 relative to the corner through rotation of the rotatable part 4, and at least one dust collection opening 6 is close to the corner, so that the cleaning blind area is eliminated. Debris, such as debris, at the corners enters the vacuum cleaner via the fluid suction path, thereby completing the cleaning operation. In this process, the plurality of rotating wheels 5 are brought into contact with the surface to be cleaned and the wall, table, etc., and are wiped with the cleaning member. When the dust collection tool 100 is used for cleaning corners, frequent manual operation of a user is not needed, and the convenience of cleaning operation is greatly improved.
The foregoing embodiments are merely illustrative of the technical concept and features of the present application, and are intended to enable those skilled in the art to understand the content of the present application and implement the same according to the content of the present application, not to limit the protection scope of the present application. All equivalent changes or modifications made in accordance with the spirit of the present application are intended to be included within the scope of the present application.
