Detailed Description

The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present application, but not all embodiments. The following description of at least one exemplary embodiment is merely exemplary in nature and is in no way intended to limit the application, its application, or uses. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.

The application provides a sweeper and cleaning equipment, which aims to solve the problems that a fan in the prior art is loud in noise and pollutes air, and the more the mop is used, the dirtier the mop is.

As shown in fig. 1 to 11, the cleaning apparatus includes a base station 2 and a sweeper 1, at least a portion of the sweeper 1 being accessible to or accessible from the base station 2.

As shown in fig. 1 to 11, the sweeper comprises a housing assembly 10, a roller 20 and a cleaning assembly 30, wherein the roller 20 is rotatably arranged on the housing assembly 10, at least one part of the roller 20 is positioned in the housing assembly 10, at least another part of the roller 20 is positioned outside the housing assembly 10, a containing cavity 11 and a cleaning cavity 12 are arranged on the housing assembly 10 at intervals corresponding to the roller 20, different positions of the circumferential outer side wall of the roller 20 respectively pass through the containing cavity 11 and the cleaning cavity 12 along with the rotation of the roller 20, and the containing cavity 11 is used for collecting garbage; at least a portion of the cleaning assembly 30 is disposed within the housing assembly 10, and the cleaning assembly 30 is in communication with the cleaning chamber 12 and is capable of providing and retrieving cleaning fluid to the cleaning chamber 12.

The part of the roller 20 positioned outside the shell assembly 10 is used for wrapping garbage and dust on the ground and driving the garbage and dust to rotate into the shell assembly 10, and the roller 20 has the functions of sweeping and washing the ground, so that a fan structure in the prior art is omitted, noise generated in the running process of the sweeper is reduced, and secondary pollution of indoor air is avoided; when the roller 20 part coated with garbage and dust rotates to the accommodating cavity 11, solid garbage is separated from the roller 20 and is collected by the accommodating cavity 11, when the roller 20 rotates to the cleaning cavity 12, the cleaning cavity 12 flowing continuously in the cleaning cavity 12 can clean the roller 20, so that the separation of the solid garbage and the liquid garbage is realized, the roller 20 can be automatically cleaned in real time in the process of cleaning the ground by the sweeper, the roller 20 cannot store dirt, and the cleaning quality and efficiency are improved. The application solves the problems that the fan in the prior art has large noise and pollutes air, and the more the mop is used, the more dirty the mop is.

As shown in fig. 8, 9 and 11, the circumferential side wall of the washing chamber 12 has at least one water inlet hole 121 and at least one water outlet hole 122, and the washing assembly 30 communicates with the washing chamber 12 through the water inlet hole 121 and the water outlet hole 122, respectively. Thus, clean cleaning liquid flows into the cleaning chamber 12 through the water inlet hole 121, and the cleaning liquid after cleaning the drum 20 flows out of the cleaning chamber 12 through the water outlet hole 122, so that the cleaning liquid in the cleaning chamber 12 flows in real time, and the cleaning liquid of the cleaning drum 20 is always clean.

As shown in fig. 6 to 8, the washing chamber 12 is disposed along the axial direction of the drum 20 corresponding to the opening of the drum 20, and the water inlet holes 121 and the water outlet holes 122 are disposed corresponding to both ends of the drum 20 in the axial direction, respectively. In this way, the water inlet holes 121 and the water outlet holes 122 are communicated with both ends of the cleaning chamber 12 in the length direction, so that a larger area where the cleaning liquid flows through the drum 20 is ensured, and the efficiency of cleaning the drum 20 is improved.

In some embodiments of the present application, the water inlet holes 121 and the water outlet holes 122 are aligned in the axial direction of the drum 20. Of course, the water inlet hole 121 and the water outlet hole 122 may be arranged in a staggered manner in the axial direction of the drum 20, and only the water inlet hole 121 and the water outlet hole 122 are required to be ensured to correspond to two axial ends of the drum 20 respectively, so that the cleaning solution can be introduced from one axial end of the drum 20 and discharged from the other axial end of the drum 20.

As shown in fig. 11, the accommodating chamber 11 is located upstream of the washing chamber 12 in the rotational direction of the drum 20. Like this, the cylinder 20 of wasing ground is earlier through holding chamber 11 to solid rubbish and is collected, washs cylinder 20 through wasing chamber 12 again, prevents that solid rubbish from getting into and wasing the intracavity and influencing the cleaning performance, and has the risk of blocking inlet opening 121 and apopore 122 to, solid rubbish and liquid rubbish separately clear up and collect, make things convenient for the clearance of user later stage.

In some embodiments of the present application, the direction of rotation of the drum 20 as shown in fig. 10 is clockwise.

As shown in fig. 10 and 11, the housing assembly 10 further has a baffle 13 and a scraping rib 14 disposed at intervals corresponding to the drum 20, the baffle 13 is close to the accommodating chamber 11 with respect to the scraping rib 14, and the baffle 13, the scraping rib 14 and at least a portion of the body portion of the housing assembly 10 enclose the cleaning chamber 12. Thus, the baffle 13 is used for separating the accommodating cavity 11 from the cleaning cavity 12, when the drum 20 drives the garbage to rotate and contact with the baffle, the baffle 13 scrapes off tiny particles, hairs and the like carried by the drum 20 and falls into the accommodating cavity 11, the drum 20 continues to rotate to the closed cleaning cavity 12, cleaning of the drum 20 is achieved, and when the drum continues to rotate through the scraping ribs 14, sewage in the drum 20 is scraped into the cleaning cavity 12 and is discharged out of the cleaning cavity 12 along with the water outlet holes 122.

In this embodiment, the baffle 13 and the scraping rib 14 are made of plastic, the scraping rib 14 may be a long straight structure or a wavy structure, and the length direction of the scraping rib 14 is the same as the axial direction of the drum 20 no matter what structure the scraping rib 14 is.

As shown in fig. 11, at least the outer surface of the drum 20 is made of a flexible material, and when the drum 20 is in contact with the barrier 13 and the beads 14, the portion of the drum 20 in contact with the barrier 13 and the beads 14 is deformed. Thus, the flexible roller 20 can cover garbage stains and rotate the roller 20 carrying the stains into the shell assembly 10, deformation occurs when the roller 20 contacts with the baffle 13 so as to block garbage on the roller 20 into the accommodating cavity 11, and deformation occurs when the roller 20 contacts with the scraping ribs 14 so as to scrape sewage on the roller 20 into the cleaning cavity 12.
