Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiment is only one embodiment of the present invention, and not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Example one

In the present embodiment, the sweeper includes a sweeper body 100, a cleaning brush plate, and other components. As shown in fig. 1 to 2, an opening is formed at the bottom of the body 100 to accommodate a cleaning brush tray, and a rotation driving module 101 and a lifting mechanism (including a lifting motor 1021 and a linkage supporting plate 1022) are disposed inside the body 100; the cleaning brush disc comprises a rotating shaft 204, impeller blades 202 and bristles 203, wherein a hollow part 201 is arranged in the middle of the rotating shaft 204, the impeller blades 202 are arranged at intervals along the rotating shaft 204 and extend to the ground to be contacted, the bristles 203 are distributed at the tail ends of the impeller blades 202 in a row shape, a bearing 205 is further fixedly arranged on the rotating shaft 204, the cleaning brush disc further comprises a housing 206, and the impeller blades 202 and the rotating shaft 204 are rotatably connected to the housing 206 and can do relative rotation movement; in the process of forming the air duct by the sweeper, the sweeper further comprises a dust box 301 and a fan 302. Since the impeller blades 202 extend from the rotating shaft 204 to the ground, in order to ensure that the stirring dust or garbage can be absorbed, the impeller blades 202 are required to be in contact with the ground at a certain angle, the included angle formed by the contact position of the single impeller blade 202 and the ground is set as theta, wherein 0 degrees < theta < 90 degrees, so that part of the impeller blades 202 can be used for cleaning the garbage on the ground, and the other part of the impeller blades 202 is used for forming an air duct for allowing the garbage to be sucked through; wherein, when theta is close to 0 degree, it means that the impeller blades 202 extend along the axial direction of the rotating shaft 204, the garbage can only be sucked into the air channel through the gaps at the middle positions of the impeller blades, and when theta is close to 90 degrees, the impeller blades 202 are spaces reserved with a certain angle with the ground, so that the garbage can be collected and passed through. It will be appreciated that the hollow space formed between the impeller blades 202 and the floor allows the refuse to be agitated and then moved along with the cyclone, and then be easily sucked into the sweeper under the suction of the wind tunnel. The cleaning brush disc is rotationally connected with the machine body 100 through a bearing 205 on a rotating shaft 204, the rotary driving module 101 drives the cleaning brush disc to rotate relative to the machine body 100 in a gear matching mode, and the impeller blades 202 extend and are distributed around the rotating shaft 204 in an arc shape and form cyclone when rotating; the lifting motor 1021 and the linkage supporting plate 1022 realize a lifting function through a mechanical matching mode, the linkage supporting plate 1022 and the housing 206 are at least partially overlapped and abutted together, and the lifting motor 1021 and the linkage supporting plate 1022 are two in number and are symmetrically distributed on two sides of the cleaning brush disc; the airflow through the hollow 201 is in turn communicated to the interior passages of the dirt box 301 and the fan 302.

As shown in fig. 1 to 2, this embodiment is a specific embodiment. In fig. 2, an operation schematic diagram of the whole machine is shown, after the rotation driving module 101 drives the cleaning brush disk to rotate to form a cyclone, stubborn dirt or garbage on the ground is stirred, and enters the dust box 301 along the hollow portion 201 under the strong suction force of the fan 302 for storage, as shown by a path F in the figure. The advantage of this embodiment is that since the plurality of impeller blades 202 are all in physical contact with the cleaning floor, the surface cleaning manner of the conventional brush rolling is changed, and the bristles 203 at the end can also clean the dirt in the crevices of the floor, thereby greatly improving the cleaning effect.

Example two

In this embodiment, a technical scheme of selective sweeping of the sweeper is shown. As shown in fig. 3 and 4, when an area needing to be intensively cleaned runs, the cleaning brush disk contacts with the ground to finish cleaning, after the rotary driving module 101 drives the cleaning brush disk to rotate to form a cyclone, stubborn dirt or garbage on the ground is stirred, and enters the dust box 301 along the hollow portion 201 under the strong suction force of the fan 302 to be stored, as shown by a path F in the figure, the distance between the lifting mechanism and the ground is L1. When the cleaning brush disc enters a non-key cleaning area to operate, the strong friction force between the cleaning brush disc and the ground can lower the operation efficiency, and therefore the lifting mechanism is required to act to enable the cleaning brush disc to leave the ground, in the specific process, the lifting motor 1021 drives the linkage supporting plate 1022 to move upwards, the cleaning brush disc integrally moves upwards relative to the machine body 100 due to the position abutting relation between the linkage supporting plate 1022 and the housing 206, the rotary driving module 101 stops driving rotation afterwards, the separation from the ground is completed, and the distance between the lifting mechanism and the ground is L2. Wherein in the aforementioned state change, L1< L2, which represents the relative displacement of the cleaning brush disk as L2-L1, a selective sweeping solution is achieved because the cleaning brush disk is selectively detached from the cleaning floor. What is needed is that in the present embodiment, the determination as to whether or not the cleaning region is important is generally made by detecting the density of the dust box 301 to generate a detection signal, and a method of detecting the dust density is already a well-established prior art.

The embodiments disclosed are merely exemplary embodiments for the purpose of illustrating the invention, and should not be considered as limiting the scope of the invention, and certainly not limiting the scope of the invention, for those skilled in the art, it will be understood that various equivalent changes, modifications, variations, etc. may be made in the claims, and all such modifications and equivalents may be included within the scope of the invention.
