Description

Technical Field

[0001] The utility model belongs to the technical field of sweeping robots, and particularly relates to a squeegee assembly. Background Art

[0002] To effectively clean liquid stains on the floor, existing robot vacuums are often equipped with a squeegee. This squeegee not only vacuums but also cleans water and dirt stains, and can even replace traditional mops for daily maintenance, significantly improving the robot's cleaning capabilities.

[0003] The wiper blade in a traditional squeegee assembly features multiple through-grooves, allowing wastewater to flow into the suction chamber, effectively cleaning dirt and stains from the floor. To ensure the airtightness of the suction chamber, the wiper blade is compressed and bent during operation to maintain close contact with the floor. This causes the size of the grooves to change with the downward pressure of the wiper blade, resulting in uncontrolled fluctuations in water inflow, which in turn affects the suction effect and efficiency. Furthermore, due to friction with the floor during use, the wiper blade can easily deform toward the center of the groove, affecting overall suction efficiency. Utility Model Content

DETAILED DESCRIPTION

[0025] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0026] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0027] like Figures 1 to 6 As shown, a squeegee assembly includes:

[0028] The suction and scraping structure 100 has a mounting groove 111;

[0029] The wiper structure 200 includes a front wiper strip 210 detachably mounted within the mounting groove 111. The front wiper strip 210 is provided with a plurality of grooves 230 along its length. Each groove 230 is recessed along the thickness of the front wiper strip 210 and has a downward opening. The depth of the recess is less than the thickness of the front wiper strip 210. Compared to the through-groove design on the wiper strip in conventional squeegee assemblies, this design avoids the problem of the grooves 230 changing in size with the bending amplitude of the front wiper strip 210, which would result in uncontrolled fluctuations in water inflow. This effectively ensures the efficient and effective water absorption of the squeegee assembly during operation. Furthermore, this design prevents the front wiper strip 210 from deforming toward the center of the grooves 230 during use, maintaining its shape and functionality, and further ensuring effective water absorption.

[0030] Specifically, if Figures 2 to 6 As shown, in this embodiment, the squeegee assembly consists of a suction squeegee structure 100, a wiper structure 200, and a roller structure 300. The suction squeegee structure 100 is used to suck up dirt and water stains, while the wiper structure 200 is used to scrape the dirt and water stains to the suction area of ​​the suction squeegee structure 100. The roller structure 300 is assembled on the suction squeegee structure 100 to assist the movement of the sweeping robot.

[0031] In this embodiment, the suction scraper structure 100 includes a mounting part 110 and a water absorbing part 120. On the one hand, this split design can improve the convenience of disassembly, cleaning and maintenance of the mounting part 110 and the water absorbing part 120. On the other hand, the front wiper strip 210 and the rear wiper strip 220 can be assembled on the suction scraper structure 100 in a snap-fit ​​manner, effectively improving the convenience of disassembly and assembly of the front wiper strip 210 and the rear wiper strip 220, and effectively improving the overall assembly efficiency of the suction scraper structure 100.

[0032] In this embodiment, the mounting member 110 is crescent-shaped, with a mounting groove 111 defined on the side facing the ground. This groove 111 extends along the length of the mounting member 110. The water absorbing member 120, the front wiper strip 210, and the rear wiper strip 220 are all detachably mounted within the groove 111, with the water absorbing member 120 positioned between the front wiper strip 210 and the rear wiper strip 220. This design effectively ensures the compactness of the suction squeegee assembly.

[0033] In this embodiment, the mounting member 110 is provided with a plurality of second connecting portions 112 along its length, corresponding one-to-one with the first connecting portions 121. Each second connecting portion 112 is a cylinder with a threaded hole, and is detachably connected to the first connecting portion 121 via screws. This design effectively ensures the secure connection between the mounting member 110 and the water absorbing member 120.

[0034] In this embodiment, a water suction pipe 113 connected to the water suction port 123 is provided on the mounting member 110. The water suction pipe 113 includes a snap-fitting port that is snap-fitted to the water suction port 123, and a water suction portion that is hollow cylindrical and extends away from the water absorbing member 120, so that the mounting member 110 can be connected to a power source to achieve the suction of stains or water stains.

[0035] In this embodiment, the mounting member 110 is further provided with a plurality of third connecting portions 114 on the side facing away from the water absorbing member 120. Each third connecting portion 114 is cylindrical, arranged along the length of the mounting member 110, and staggered relative to the second connecting portion 112. Each third connecting portion 114 is provided with an internal thread. This design allows the mounting member 110 to be easily assembled onto the housing of the robot vacuum cleaner and forms a secure connection therewith, thereby ensuring the stability of the squeegee assembly.

[0036] In this embodiment, the shape of the water absorbent member 120 matches that of the mounting groove 111. It is provided with multiple first connecting portions 121 on the side facing the mounting member 110. Each first connecting portion 121 is cylindrical and arranged along the length of the water absorbent member 120, corresponding one-to-one with a second connecting portion 112. Each first connecting portion 121 is internally threaded. This design ensures a secure and stable connection between the water absorbent member 120 and the mounting member 110.

[0037] In this embodiment, a converging channel 122 is provided on the side of the water absorbing member 120 facing away from the mounting member 110. This converging channel 122 is shaped like a figure eight, and a water suction port 123 is provided at the center of the water absorbing member 120, extending through the member and communicating with the converging channel 122. This design ensures more uniform water flow distribution and improves water absorption efficiency. Furthermore, the connection between the water suction port 123 and the converging channel 122 concentrates the water flow, increasing the negative pressure within the water absorption chamber and further enhancing the water absorption effect.

[0038] In this embodiment, the wiper structure 200 includes a front wiper strip 210 and a rear wiper strip 220, which are detachably mounted within the mounting groove 111. The front wiper strip 210 and the rear wiper strip 220 are arranged opposite each other with a gap therebetween. The front wiper strip 210 and the rear wiper strip 220 cooperate with the mounting groove 111 to form a water suction cavity. This design enables the wiper structure 200 to form a sealed cavity with the ground during operation, thereby facilitating the suction of dirt or water stains by the squeegee structure 100, effectively enhancing the squeegee assembly's ability to collect and discharge wastewater, and improving cleaning effectiveness.

[0039] In this embodiment, the front wiper strip 210 and the rear wiper strip 220 are rectangular strips and are elastic members. Preferably, the front wiper strip 210 and the rear wiper strip 220 are rubber sheets. This design allows the front wiper strip 210 and the rear wiper strip 220 to bend when subjected to force, thereby better conforming to the ground, effectively improving their contact with different surfaces and their water absorption effect. In addition, the elastic members can reduce the hard contact between the wiper strips and the ground, extending their service life.

[0040] To facilitate the entry of dirt or water scraped by the front wiper strip 210 into the water absorption chamber, in this embodiment, the front wiper strip 210 is provided with a plurality of inverted U-shaped grooves 230 along its length. Each groove 230 is recessed along the thickness of the front wiper strip 210 and has a downward opening. The depth of the recess is less than the thickness of the front wiper strip 210. This design allows water to enter the water absorption chamber through the grooves 230 when the front wiper strip 210 is bent, while also ensuring a constant water intake. This effectively prevents the water intake of the front wiper strip 210 from varying with the bending amplitude, thereby effectively improving the water absorption efficiency and effectiveness of the squeegee assembly. Furthermore, this design means that the grooves 230 do not penetrate the front wiper strip 210, preserving a certain material thickness. This ensures that the material surrounding the grooves 230 has sufficient strength and toughness to resist deformation when the front wiper strip 210 is rubbed by the ground, further improving cleaning effectiveness and service life.

[0041] In this embodiment, the front wiper strip 210 includes a first mounting surface 211 and a second mounting surface 212 arranged opposite each other. The grooves 230 include a plurality of first grooves 231 on the first mounting surface 211 and a plurality of second grooves 232 on the second mounting surface 212, with the first and second grooves 231 and 232 arranged alternately. This design ensures that a small ventilation path is always present within the water absorption chamber, whether the front wiper strip 210 is bent forward or backward. Even if one side of the front wiper strip 210 is completely in contact with the ground, the grooves 230 on the other side provide necessary ventilation, preventing the water absorption chamber from being completely closed, thereby ensuring smooth movement of the sweeping robot. This alternating design ensures more even force distribution across the wiper strip, avoiding localized deformation or wear caused by uneven force on one side. This improves the stability and conformity of the wiper strip, thereby enhancing water absorption.

[0042] In this embodiment, the rear wiper strip 220 has a certain curvature and is longer than the front wiper strip 210. When the rear wiper strip 220 and the front wiper strip 210 are installed in the mounting groove 111, the ends of the front wiper strip 210 abut against the rear wiper strip 220. This design increases the contact area between the front and rear wiper strips 210 and improves the sealing of the water absorption chamber. This good sealing prevents external air from entering the water absorption chamber, maintaining a negative pressure inside and thus improving water absorption efficiency. Furthermore, the rear wiper strip 220 is longer than the front wiper strip 210, ensuring that the front wiper strip 210 is evenly stressed across its entire width, avoiding the problem of uneven localized pressure.

[0043] Preferably, in this embodiment, the overall height of the rear wiper strip 220 is greater than that of the front wiper strip 210. That is, after the rear wiper strip 220 and the front wiper strip 210 are installed in the mounting groove 111, the bottom of the rear wiper strip 220 is lower than the bottom of the front wiper strip 210. This design provides a greater bending area for the rear wiper strip 220 than for the front wiper strip 210 at the same downward pressure height, thereby increasing the contact area between the rear wiper strip 220 and the ground, ensuring a tight fit and seal between the rear wiper strip 220 and the ground, and effectively removing dirt and water stains.

[0044] In this embodiment, two groups of roller structures 300 are provided, which are detachably connected to the mounting member 110 through fasteners. Preferably, the roller structure 300 is suspended on the outside of the mounting member 110. This design not only assists the movement of the sweeping robot, but also prevents the squeegee assembly from being hit during use.

[0045] The squeegee assembly provided by the embodiment of the present invention is assembled by first inserting the front wiper strip 210 and the rear wiper strip 220 into the mounting groove 111, then pressing the water absorbing member 120 between the front wiper strip 210 and the rear wiper strip 220, and connecting the first connecting portion 121 and the second connecting portion 112 with screws. Finally, the roller assembly is mounted on the mounting member 110. It is worth noting that the tightness of the connection between the water absorbing member 120 and the front wiper strip 210 and the rear wiper strip 220 can be adjusted by adjusting the tightness of the screws connecting the first connecting portion 121 and the second connecting portion 112.
