Description

Scrubbing brush subassembly and surface cleaning equipment

Technical Field

The present disclosure relates to a floor brush assembly and a surface cleaning apparatus.

Background

Surface cleaning apparatuses may include dry surface cleaning apparatuses, which may be exemplified by cleaning tools such as vacuum cleaners, and wet surface cleaning apparatuses, which may be exemplified by cleaning tools such as floor washers.

When the surface cleaning device is used, a rotating rolling brush or brush roller and other structures are generally arranged, dust on the surface to be cleaned is stirred by the rolling brush or the brush roller, then the dust is sucked to the processing device through the suction port to be separated from air, solid garbage such as the dust is kept inside the surface cleaning device, and clean air is exhausted to the outside of the surface cleaning device.

The rotation of the cylindrical agitator causes the bristles to sweep across the carpet surface and agitate the fibers of the carpet and, in conjunction with the result of the vacuum pumping action, dislodge the soil from the carpet fibers. During removal, hair or other threads may become entangled around the brush bar or its attachment. This can lead to poor performance of the surface cleaning apparatus.

With continued reference to fig. 5 and 6, the first stirring body 500 of the present disclosure is laterally disposed, for example, laterally disposed, in the accommodating space. Wherein, when the surface cleaning apparatus is in use, a user moves the floor brush assembly forwards or backwards, whereby the front-to-back direction of the floor brush assembly, i.e. the longitudinal direction of the floor brush assembly, is substantially perpendicular to said longitudinal direction. Those skilled in the art will appreciate that the first stirring body 500 is transversely disposed does not mean that the rotation axis OX of the first stirring body 500 is perpendicular to the longitudinal direction, but the rotation axis OX may be at a predetermined angle with the longitudinal direction, and the predetermined angle may be within a certain range. Moreover, the transverse direction does not refer to the horizontal direction, and the transverse direction can form a certain included angle with the horizontal direction.

As shown in fig. 6, in the present disclosure, the first stirring bodies 500 are provided in two, and the free ends of the two first stirring bodies 500 are disposed close to each other and have a preset distance; thereby forming a gap between the two free ends of the first stirring body 500.

In another embodiment, as shown in fig. 7, the support part 150 is formed with a bearing seat, and the bearing 400 is provided to the bearing seat of the support part 150, thereby indirectly providing the bearing 400 to the housing part 200.

More preferably, as shown in fig. 7, the support part 150 is formed with a stepped part 151, and the bearing 400 can be positioned by the stepped part 151; accordingly, the support part 150 is further formed with a hook part 152, and the bearing 400 can also be positioned by the hook part 152.

In a preferred embodiment, the number of bearings 400 is two, for example provided as two ball bearings. Of course, the two bearings 400 may be arranged as angular contact bearings mounted back-to-back or face-to-face.

The outer ring of one of the two bearings 400 is positioned by the step 151 and the outer ring of the other of the two bearings 400 is positioned by the hook 152, thereby achieving fixation of the axial positions of the two bearings 400.

As shown in fig. 7, the floor brush assembly 10 of the present disclosure further includes a driving rod 410, wherein the driving rod 410 is disposed on the bearing 400 and is rotatably supported by the bearing 400, that is, the driving rod 410 may be fixed to an inner ring of the bearing 400, for example, the driving rod 410 may have a size slightly larger than an inner diameter of the inner ring of the bearing 400, so that the driving rod 410 cannot move axially relative to the bearing 400 by means of an interference fit.

Also, due to the characteristics of the bearing 400, the driving rod 410 can rotate, and at this time, the driving device 160 can drive the driving rod 410 to rotate.

In the present disclosure, one end of the driving lever 410 is located at the accommodating space 210, and the first agitating body 500 is mounted at the end; the other end of the driving lever 410 is located outside the receiving space 210, and a driven timing pulley 180 is mounted at the end.

At this time, the bearing 400 is configured such that: when the first stirring member 500 is mounted on the driving lever 410, the first stirring member 500 is rotatably held in the housing portion 200 in a state where the outer circumferential surface of the bearing 400 (i.e., the outer circumferential surface of the outer ring of the bearing 400) contacts the housing portion 200; and the outer diameter of the bearing 400 is less than or equal to the maximum diameter of the outer circumferential surface of the first agitating body 500.

Thus, the first stirring body 500 can be stably supported by the arrangement of the bearing 400, and the operation stability of the floor brush assembly 10 is improved, thereby improving the cleaning effect of the surface to be cleaned.

In one embodiment, the outer diameter of the bearing 400 is smaller than or equal to the outer diameter of the end of the first stirring body 500 fixed to the driving rod 410.

In another embodiment, the outer diameter of the bearing 400 is less than or equal to the minimum outer diameter of the outer circumferential surface of the first stirring body 500. For example, the outer diameter of the bearing 400 is smaller than or equal to the outer diameter of the end of the first stirring body 500 away from the driving rod 410.

In the present disclosure, as shown in fig. 7, the driving rod 410 includes a driving shaft 411 and a driving member 412, wherein one end of the driving shaft 411 passes through the bearing 400 and is at least partially located in the accommodating space 210, and the driving member 412 is mounted at the one end of the driving shaft 411 and is located in the accommodating space 210; the driven synchronous pulley 180 is fixed to the driving shaft 411, and the driving member 412 is in transmission connection with the first stirring body.

More preferably, the pair of tapered inner walls includes a junction, i.e., a position where the two tapered inner walls meet, the junction corresponding to a position of a gap between the free ends of the pair of first agitating bodies 500. Further, the position of the junction corresponds to the position of the suction inlet 220.

More preferably, the floor brush assembly may further include a second stirring body 600, the second stirring body 600 is rotatably disposed at the housing portion 200 and located in front of the first stirring body 500, and a portion of the vacuuming flow channel is formed between the first stirring body 500 and the second stirring body 600, so that the surface to be cleaned can be cleaned more cleanly by the arrangement of the first stirring body 500 and the second stirring body 600. Specifically, when the surface cleaning apparatus cleans a surface to be cleaned with the floor brush assembly moving forward, the surface to be cleaned is first cleaned by the second agitating body 600, agitating dust on the surface to be cleaned; and then the surface to be cleaned is cleaned again by the first agitating body 500, agitating the dust on the surface to be cleaned, thereby making the surface to be cleaned cleaner after cleaning.
