Description

Technical Field

[0001] This utility model relates to the field of cleaning robot technology, specifically to an anti-tangling cleaning roller assembly for a cleaning robot. Background Technology

[0002] The cleaning roller is one of the core cleaning components of a cleaning robot. It is mainly used to contact the floor surface through rotation, agitate and collect debris (such as dust, hair, and filaments), and then use vacuum suction to suck it into the robot.

[0003] A reference can be made to Chinese Utility Model Patent CN213850515U, which discloses a robotic cleaner with dual cleaning rollers. This robotic cleaner includes: a housing, a suction conduit with an opening, and a guide roller mounted in front of the brush roller. An inter-roller air passage can be defined between the guide roller and the brush roller, wherein a lower portion of the guide roller is exposed to a flow path leading to the suction conduit, and an upper portion of the guide roller is outside the flow path. Optionally, the combing unit includes a plurality of combing protrusions extending into the guide roller and having a leading edge not aligned with the center of the guide roller. Optionally, a sealing strip is arranged along the rear side of the opening and a portion of the left and right sides of the opening. The lower side can define a side-edge vacuum passage extending partially between the guide roller and the sealing strip from the side of the housing toward the opening.

[0004] During the use of the aforementioned robotic cleaner, the cleaning roller will first come into contact with hair and long strips of debris. In order to ensure the cleaning effect, the bristles on the surface of the cleaning roller will cause long strips of debris such as hair to get tangled on the surface of the cleaning roller. After a certain amount of accumulation, it will affect the cleaning effect and may even cause the cleaning roller to get stuck. In addition, the surface of the existing cleaning roller will get dirty during use, which will affect the cleaning effect of the cleaning roller. Utility Model Content

[0014] Beneficial effects

[0015] This invention provides an anti-tangling cleaning roller assembly for a cleaning robot. Compared with the prior art, it has the following advantages:

[0016] (1) The anti-tangling cleaning roller assembly of the cleaning robot is configured with seven rubber rollers, which are equidistantly installed on the outside of the drive shaft. The end of the hook blade is located between adjacent rubber rollers and does not contact the surface of the drive shaft. When the drive shaft drives the brush to rotate and rolls in the hair, the hook blade can hook up the hair on the surface of the brush and cut the hair with the help of the arc-shaped blade. The toothed blade can straighten the hair and cut the tangled hair, further shredding the tangled hair so that it can be thrown out when the brush rotates, preventing the hair from tangling and affecting the cleaning effect.

[0017] (2) The anti-tangling cleaning roller assembly of the cleaning robot, through the setting of the diversion pipe, due to the reduced diameter of the end hole of the branch structure of the diversion pipe, allows the water flow to wash the brush on the outside of the rubber roller at high speed, wetting the brush. Since the brush bristles are kept rotating, the wetted brush will hit the upper surface of the scraper, causing the sewage carried by the brush bristles to splash onto the scraper surface under the influence of inertia, and enter the sewage tank under the guidance of the scraper. The micro liquid pump can extract the sewage inside the sewage tank through the connecting pipe and transport it to the corresponding cavity inside the water tank through the sewage discharge pipe to clean the roller body and prevent the dirt carried by it from affecting the cleaning effect.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 This utility model provides a technical solution: an anti-tangling cleaning roller assembly for a cleaning robot, including a housing 1, with a cleaning mechanism 2 disposed on the upper part of the housing 1.

[0025] A cleaning assembly 21, located inside the housing 1, is used to clean stains on the floor. The cleaning assembly 21 includes a drive shaft 211 inserted into the housing 1, rubber rollers 212 inserted onto the outer side of the drive shaft 211, limit wheels 213 inserted at both ends of the drive shaft 211, and brush bristles 214 fixedly mounted on the outer side of the rubber rollers 212. The cleaning assembly 21 also includes hook blades 215 and toothed blades 216 fixedly mounted on the inner wall of the housing 1. The drive shaft 211 and the housing 1 are rotatably connected. The outer side of the rubber rollers 212 has spiral plate-shaped protrusions. There are seven rubber rollers 212 in total, equidistantly mounted on the drive shaft. On the outer side of 211, the center of the limiting wheel 213 is provided with dense fibers. The limiting wheel 213 is symmetrically installed on both ends of the transmission shaft 211 with the center of the transmission shaft 211 as the reference. The bristles 214 are in a clump shape and are interspersed between the spiral plate-shaped protrusions of the rubber roller 212. The length of the bristles 214 is greater than the height of the protrusions of the rubber roller 212. The end of the hook blade 215 is located between the adjacent rubber rollers 212 and the end of the hook blade 215 does not contact the surface of the transmission shaft 211. The cutting edge of the hook blade 215 is located inside the arc-shaped structure. The cutting edges of the hook blade 215 and the toothed blade 216 point in the opposite direction to the rotation direction of the transmission shaft 211.

[0026] Specifically, the outer casing 1 can restrict the position of the drive shaft 211. Both ends of the drive shaft 211 can be connected to a motor to drive the rubber roller 212 and the bristles 214 on the outside of the rubber roller 212 to rotate. The fibers distributed in a ring at the center of the limiting wheel 213 can restrict the position of the hair when the limiting wheel 213 rotates, preventing the hair from directly wrapping around the connection between the drive shaft 211 and the outer casing 1. The bristles 214 can clean the ground when rotating. The tip of the hook blade 215 is close to the surface of the drive shaft 211. When the drive shaft 211 drives the bristles 214 to rotate and roll in the hair, the hook blade 215 can hook up the hair on the surface of the bristles 214 and cut the hair with the help of the arc-shaped blade edge, cutting the hair into small segments. The toothed blade 216 can straighten the hair and cut the tangled hair so that the hair can be thrown out when the bristles 214 rotates.

[0027] The cleaning assembly 22 includes a water tank 221 fixedly installed on the front side of the outer casing 1. A top cover 222 is fixedly installed on the top of the water tank 221. A drain pipe 223 and a delivery pipe 224 are inserted through the top of the top cover 222. The cleaning assembly 22 also includes a diversion pipe 225 and a connecting pipe 226 fixedly installed on the top of the outer casing 1. A micro liquid pump 227 is fixedly installed at the upper end of the diversion pipe 225 and the connecting pipe 226. The cleaning assembly 22 also includes a sewage tank 228 fixedly installed inside the outer casing 1. A scraper 229 is fixedly installed on one side of the sewage tank 228. A distribution point is provided in the center of the water tank 221. The water tank 221 has a partition, and a drain outlet and a water inlet are respectively provided on the left and right sides of the bottom end. The drain pipe 223 and the conveying pipe 224 pass through the top cover 222 and are connected to the two chambers of the water tank 221 respectively. The drain pipe 223 is connected to the outlet of the corresponding micro liquid pump 227, and the conveying pipe 224 is connected to the inlet of the corresponding micro liquid pump 227. The branch end of the diversion pipe 225 points to the drive shaft 211. The bottom end of the connecting pipe 226 is located inside the sewage tank 228. The scraper 229 is fixedly installed on the side of the sewage tank 228 near the bristles 214, and the scraper 229 is in contact with the bristles 214.

[0028] Specifically, the cavity on one side of the water tank 221 is used to store sewage, and the cavity on the other side is used to store clean water. The micro liquid pump 227 can pump clean water into the interior of the diversion pipe 225 through the connecting pipe 226. Due to the reduced diameter of the end hole of the branch structure of the diversion pipe 225, the water flow can wash the brush on the outside of the rubber roller 212 at high speed, wetting the brush. Since the bristles 214 are kept rotating, the wetted brush will hit the upper surface of the scraper 229, causing the sewage carried by the bristles 214 to splash onto the surface of the scraper 229 under the influence of inertia, and enter the sewage tank 228 under the guidance of the scraper 229. The micro liquid pump 227 can extract the sewage from the sewage tank 228 through the connecting pipe 226 and transport it to the corresponding cavity inside the water tank 221 through the drain pipe 223. At the same time, the contents not described in detail in this specification are all prior art known to those skilled in the art.

[0029] During operation, there are seven rubber rollers 212, equidistantly mounted on the outside of the drive shaft 211. The ends of the hook blades 215 are located between adjacent rubber rollers 212, and the ends of the hook blades 215 do not contact the surface of the drive shaft 211. When the drive shaft 211 drives the bristles 214 to rotate and roll in hair, the hook blades 215 can hook up the hair on the surface of the bristles 214 and cut the hair with the help of the arc-shaped cutting edge. The toothed blades 216 can straighten the hair and cut the tangled hair, further chopping the tangled hair so that it can be thrown out when the bristles 214 rotates, preventing hair from tangling and affecting the cleaning effect. Due to the diversion pipe 22 The reduced end aperture of the 5-branch structure allows water to flow at high speed to wash the brushes on the outside of the rubber roller 212, wetting the brushes. Since the bristles 214 remain rotating, the wetted brushes will impact the upper surface of the scraper 229, causing the wastewater carried by the bristles 214 to splash onto the surface of the scraper 229 under the influence of inertia. Under the guidance of the scraper 229, the wastewater enters the wastewater tank 228. The micro liquid pump 227 can extract the wastewater from the wastewater tank 228 through the connecting pipe 226 and transport it to the corresponding cavity inside the water tank 221 through the drain pipe 223 to clean the roller body and prevent the dirt carried by the rollers from affecting the cleaning effect.
