Description

Technical Field

[0001] This utility model relates to the field of sweeping robot structure, and in particular to a sweeping robot scraper structure. Background Technology

[0002] With the improvement of living standards and the development of technology, more and more families are starting to use robotic vacuum cleaners. The cleaning modules of existing robotic vacuum cleaners generally include side brushes and roller brushes. The side brush is located on one side of the bottom of the robot, while the roller brush is located in the center of the bottom. During cleaning, the side brush sweeps debris from the surrounding area to the bottom of the robot, and then the roller brush mainly sweeps the debris from the floor into the dustbin. The roller brush is installed in an opening on the bottom of the robot and needs to be further secured by a roller brush cover. The roller brush cover has openings to expose the roller brush and scrapers that work in conjunction with the roller brush for cleaning. During cleaning, the scrapers contact the floor to remove dust, water stains, and other debris, and the roller brush sweeps the debris into the robot's dustbin.

[0003] like Figure 1 As shown, this is a traditional scraper structure. A mounting part is located at the top of the scraper structure, and the scraper is fixed to the robot's shell via this part. A cleaning part, which contacts the ground, is located at the bottom of the scraper. The mounting part and the cleaning part are connected by a floating part, which allows the cleaning part to swing at a certain angle. However, in some robot vacuum models, the mounting part of the scraper is positioned high, requiring a longer overall length for both the floating part and the cleaning part. This causes the cleaning part to easily flip over when encountering rough surfaces or large particles during cleaning, meaning it folds in the opposite direction of the robot's movement. This not only prevents the cleaning part from working properly but also makes it prone to breakage. Therefore, it is necessary to develop a scraper structure for robot vacuums to solve these problems. Utility Model Content

[0004] The purpose of this invention is to provide a scraper structure for a sweeping robot to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A robotic vacuum cleaner scraper structure includes an installation part, a floating part, a cleaning part, and an anti-bend part, all integrally formed from elastic material. The upper and lower ends of the floating part are connected to the installation part and the cleaning part, respectively. The lower end of the cleaning part is inclined away from the installation part. The anti-bend part is connected to the lower part of the floating part. One end of the anti-bend part is provided with an arc-shaped groove that connects to the upper end of the cleaning part. The other end of the anti-bend part is provided with an L-shaped limiting groove, which is composed of a horizontal limiting plane and a vertical limiting plane.

[0007] Further description of the present invention: The anti-bending part is also provided with multiple sets of lateral limiting holes, the lateral limiting holes opening downward and the openings corresponding to the horizontal limiting plane.

[0008] Further description of the present invention: multiple sets of lateral limiting holes are provided along the length direction of the anti-bending part, and the spacing between the multiple sets of lateral limiting holes in the middle of the anti-bending part is greater than the spacing between the multiple sets of lateral limiting holes on both sides of the anti-bending part.

[0009] Further description of this utility model: The lower end of the mounting part is provided with a downwardly protruding mounting boss.

[0010] Further description of the present invention: The lower end of the mounting part is also provided with a guide groove, which is located on the side of the mounting boss near the bending part, and the guide groove is trapezoidal.

[0011] Further description of the present invention: The upper end of the floating part is provided with a first dust guiding slope, and the end of the cleaning part away from the arc groove is provided with a second dust guiding slope that connects with the first dust guiding slope.

[0012] Further description of this utility model: The lower end of the cleaning part is uniformly provided with multiple sets of cylindrical blind holes.

[0013] Further description of the present invention: The cleaning part includes an integrally formed elastic part and a reinforcing plate. Two sets of reinforcing plates are provided and are respectively corresponding to the two ends of the elastic part in the length direction. The hardness of the reinforcing plate is greater than that of the elastic part.

[0014] Further description of this utility model: It adopts rigid TPU material.

[0015] The beneficial effects of this utility model are as follows: The scraper is fixed to the shell of the sweeping robot via the mounting part, and the L-shaped limiting groove on the anti-bending part is placed on the protruding structure on the shell. Specifically, the horizontal limiting plane is placed on the upper surface of the protruding structure, thereby quickly limiting the height position of the sweeping part. When the sweeping robot is running, the sweeping part contacts the ground and sweeps away debris. In conjunction with the roller brush and suction mechanism, the debris is swept into the collection chamber of the sweeping robot. When the sweeping part scrapes the ground, it drives the vertical limiting plane to abut against the side wall of the protruding structure. When the sweeping part receives greater resistance, it can elastically deform towards the arc-shaped groove. Due to the support and limiting effect of the anti-bending part on the floating part, the swing radius of the sweeping part is reduced, thereby preventing the sweeping part from deforming too much and flipping in the opposite direction of travel, thus ensuring the normal operation of the sweeping part and improving its service life.

[0026] The present invention will be further described below with reference to the accompanying drawings:

[0027] like Figures 1 to 5 As shown, a robot vacuum cleaner scraper structure includes an installation part 1, a floating part 2, a cleaning part 3, and an anti-bend part 4, all integrally formed from elastic material. The upper and lower ends of the floating part 2 are connected to the installation part 1 and the cleaning part 3, respectively. The lower end of the cleaning part 3 is inclined away from the installation part 1. The anti-bend part 4 is connected to the lower part of the floating part 2. One end of the anti-bend part 4 is provided with an arc-shaped groove 41 that connects to the upper end of the cleaning part 3. The other end of the anti-bend part 4 is provided with an L-shaped limiting groove 42, which is composed of a horizontal limiting plane 421 and a vertical limiting plane 422.

[0028] The scraper blade is fixed to the robot vacuum's housing via the mounting part 1. The L-shaped limiting groove 42 on the anti-bend part 4 rests on the protruding structure on the housing. Specifically, the horizontal limiting plane 421 rests on the upper surface of the protruding structure, thereby quickly limiting the height position of the cleaning part 3. When the robot vacuum is running, the cleaning part 3 contacts the ground and sweeps away debris. In conjunction with the roller brush and suction mechanism, the debris is swept into the robot vacuum's collection chamber. When the cleaning part 3 scrapes the ground, it drives the vertical limiting plane 422 to abut against the side wall of the protruding structure. When the cleaning part 3 receives greater resistance, it can elastically deform towards the arc-shaped groove 41. Due to the support and limiting effect of the anti-bend part 4 on the floating part 2, the swing radius of the cleaning part 3 is reduced, thereby preventing the cleaning part 3 from undergoing large deformation and flipping in the opposite direction of travel, thus ensuring the normal operation of the cleaning part 3 and improving its service life.

[0029] The anti-bending part 4 is also provided with multiple sets of lateral limiting holes 43, which open downwards and correspond to the horizontal limiting plane 421. By providing lateral limiting holes 43 and fitting them onto the limiting boss on the protruding structure of the sweeping robot, the anti-bending part 4 can be prevented from moving along the length of the scraper during use, thus improving the positional accuracy of the scraper.

[0030] Multiple sets of lateral limiting holes 43 are arranged along the length of the bending-resistant part 4. The spacing between the multiple sets of lateral limiting holes 43 in the middle of the bending-resistant part 4 is greater than the spacing between the multiple sets of lateral limiting holes 43 on both sides of the bending-resistant part 4. The different spacing of the lateral limiting holes 43 in the middle and on both sides of the bending-resistant part 4 can play a role in preventing errors and facilitate the rapid positioning and installation of the bending-resistant part 4.

[0031] The lower end of the mounting part 1 is provided with a downward protruding mounting boss 11. The mounting boss 11 is inserted into the groove of the housing, and the mounting part 1 is pressed into the groove of the housing by a pressure plate.

[0032] The lower end of the mounting part 1 is also provided with a guide groove 12. The guide groove 12 is located on the mounting boss 11 on the side near the anti-bending part 4. The guide groove 12 is trapezoidal and its shape matches the mounting position on the housing, so as to guide the installation of the mounting part 1.

[0033] The upper end of the floating part 2 is provided with a first dust guiding slope 21, and the end of the cleaning part 3 away from the arc groove 41 is provided with a second dust guiding slope 31 that connects with the first dust guiding slope 21. The debris scraped by the cleaning part 3 is conveyed upward through the second dust guiding slope 31 and the first dust guiding slope 21 in sequence with the cooperation of the roller brush, and the debris is collected into the collection chamber by the airflow generated by the suction structure.

[0034] The lower end of the cleaning part 3 is uniformly provided with multiple sets of cylindrical blind holes, which can reduce the contact area between the cleaning part 3 and the ground, thereby reducing friction and reducing noise generation when scraping smooth surfaces such as ceramic floors.

[0035] The cleaning part 3 includes an integrally formed elastic part 32 and a reinforcing plate 33. Two sets of reinforcing plates 33 are provided, corresponding to both ends of the elastic part 32 along its length. The hardness of the reinforcing plate 33 is greater than that of the elastic part 32. By providing reinforcing plates 33 at both ends of the elastic part 32, the reinforcing plates 33, with their greater hardness, can suppress the deformation of the elastic part 32. Even if the elastic part 32 encounters significant resistance during scraping, it is less likely to buckle.

[0036] The scraper structure is made of rigid TPU material, which has moderate elasticity and is inexpensive.

[0037] The above does not limit the technical scope of this utility model. Any modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of this utility model shall still fall within the scope of the technical solution of this utility model.
