The cleaner floor brush 1 includes a cover plate 2 and a main body 3. One of the main body 3 and the cover plate 2 has a guide rib plate, in this embodiment, the cover plate 2 has a guide rib plate 21 as an example, in other embodiments, the guide rib plate 21 may be provided on the main body 3, and depending on whether the floor brush 1 is manufactured, the guide rib plate 21 is formed on the main body 3 or the cover plate 2, which is not limited herein.

In the present embodiment, the guiding rib plate 21 is disposed at the air inlet of the floor brush 1, and the guiding rib plate 21 guides the angle at the first end far away from the air inlet, where the shape of the guiding angle is not limited, and the guiding angle may be an oblique angle or an arc angle, and the guiding angle is taken as an example for description below. That is, the contact surfaces of the guide rib plate 21 with the main body 3 and the cover plate 2 are different in area, and preferably, the contact surface of the guide rib plate 21 with the main body 3 is smaller in area than the contact surface of the guide rib plate 21 with the cover plate 2.

The design of the guide angle can effectively improve the condition that the airflow sucked at the suction port generates vortex. Further, the guide rib plates 21 are arranged at the vortex points of the floor brush 1, so that the guide structure (the guide rib plates 21) is arranged at the vortex points, so that the vortex is eliminated, and the air, dust, water flow and other media can effectively enter the pipeline, and the cleaning effect is better, as shown in fig. 2, the number of the vortex points is 2, and the floor brush 1 is provided with the two guide rib plates 21 corresponding to the positions.

When the floor brush 1 works, airflow is guided by the guide rib plates 21 at the vortex points after entering from the air inlet, no vortex is formed, or only weak vortex is formed, the suction force is greatly enhanced, and a better cleaning effect can be achieved.

Specifically, a first end of the guide rib plate 21 is chamfered to form a first face 211, the guide rib plate 21 has a second face 212 and a third face 213 connected to the first face 211, the second face 212 is opposite to the third face 213, and the second face 212 and the third face 213 connect the main body 3 and the cover plate 2, that is, the guide rib plate 21 supports the main body 3 and the cover plate 2 to prevent deformation.

In addition, the second surface 212 and the third surface 213 also include an inclined surface or an arc surface with a chamfer, and thus, the design of the inclined surface of the first surface 211 is matched, so that the vortex condition at the air inlet can be further improved.

That is, the guide rib plate 21 greatly improves the vortex condition at the air inlet by means of three-sided bevel angle guiding, and the guide rib plate 21 can support the main body 3 and the cover plate 2 and also can prevent the deformation of the two.

In addition, as shown in fig. 2 and 4, the floor brush 1 may be provided with a middle guide rib plate 22 at a middle position in addition to the guide rib plate 21 at the air inlet position. The middle guide rib plate 22 is supported and arranged at the middle parts of the cover plate 2 and the main body 3, and can also play a supporting role.

The shape of the middle guide rib plate 22 (diamond shape, or drop shape) as shown in fig. 4, the air inlet duct of the floor brush 1 is divided into two bell-mouthed air ducts by the middle guide rib plate 22, as shown in fig. 1, the shape of the floor brush 1 is that the opening at the air inlet is the largest, and then the air inlet is gradually reduced. So, when scrubbing brush 1 admitted air, middle part direction gusset 22 from the well spaced apart messenger's air current reposition of redundant personnel, leading-in left and right sides, and the medium gets into the back and makes the velocity of flow constantly increase through the pipeline that narrows down gradually, inhales the medium in the pipeline fast to increase velocity of flow, suction, and then improved clear effect greatly.

In this embodiment, the floor brush 1 is provided with the guide rib plate 21 and the middle guide rib plate 22, and in other embodiments, the floor brush 1 may also be provided with the guide rib plate 21 or the middle guide rib plate 22 separately according to the actual cleaning requirement.

The suction efficiency is improved by adding the guide rib plates, and in other embodiments, the air inlet section shape of the pipeline can be structurally adjusted to improve and eliminate vortex, so that air, dust, water flow and other media can more effectively enter the pipeline.

As shown in fig. 1 and 7, the width of the air inlet duct of the floor brush 1 decreases from the air inlet to the inside (the floor brush 1 is similar to a triangle), and the height increases (L1 < L2).

As shown in fig. 8 and 9, when the ratio of the outlet sectional area S2 to the inlet sectional area S1 of the air inlet duct ranges from 90% to 110%, the suction efficiency is high, and when the outlet sectional area S2 and the inlet sectional area S1 of the air inlet duct are equal, the suction efficiency is optimal. That is, as shown in fig. 8 and fig. 9, when the sectional area (S2) of the innermost flared end (narrowest portion) of the air inlet duct is approximately equal to the sectional area (S1) of the air inlet, a better suction efficiency point can be achieved, the efficiency is the best when S1= S2, and the error is preferably about 10%.

The invention also provides a dust collector which comprises any one of the dust collector floor brushes.

In conclusion, the floor brush provided by the invention can effectively improve the condition that the airflow sucked at the suction port generates vortex by arranging the guide rib plate with the bevel guide angle at the air inlet. Furthermore, a middle guide rib plate is arranged to improve the suction efficiency for the second time. In addition, through the accurate design of the sectional area of the air duct, better or optimal suction efficiency can be achieved.

It should be understood that although the present description refers to embodiments, not every embodiment contains only a single technical solution, and such description is for clarity only, and those skilled in the art should make the description as a whole, and the technical solutions in the embodiments can also be combined appropriately to form other embodiments understood by those skilled in the art.

The above-listed detailed description is merely a detailed description of possible embodiments of the present invention, and it is not intended to limit the scope of the invention, and equivalent embodiments or modifications made without departing from the technical spirit of the present invention are intended to be included within the scope of the present invention.
