Description

Technical Field

[0001] This invention relates to the field of cleaning appliance technology, specifically to an air pump-driven auxiliary cleaning scraper assembly and its usage method. Background Technology

[0002] In recent years, with the explosive growth of the smart home industry and users' pursuit of a high-quality living environment, smart cleaning devices such as home cleaning robots and floor scrubbers have undergone rapid technological iteration and market penetration. Among the many cleaning technologies, friction cleaning solutions based on rotating roller brushes have become the mainstream configuration for floor cleaning equipment due to their efficient stain removal capabilities. The core working mechanism of such devices usually relies on the direct contact between the roller brush assembly and the ground. Through the mechanical friction generated by the high-speed rotation of the roller brush, combined with water flow or cleaning liquid, solid and liquid stains on the ground are wiped away and sucked up. Although the cleaning capabilities of existing cleaning equipment in open areas are relatively mature, there are still shortcomings. Because most roller brushes adopt a cylindrical design with a circular cross-section, when facing a 90-degree angle where two perpendicular walls intersect, the outer contour of the circular roller brush cannot perfectly match the geometry of the right angle vertex. The roller brush can only rely on the tangential contact between its cylindrical surface and the wall, and cannot penetrate into the vertex area of ​​the corner. This geometric mismatch creates an approximately triangular "cleaning blind spot" at the corner, which severely impacts the user experience and actual cleaning effectiveness of the cleaning equipment.

[0003] In current floor scrubbers and roller brush cleaning equipment, cleaning squeegees are usually placed on the side or top of the roller brush to clean the blind spots. Most cleaning squeegees on the market are made of rigid materials or semi-rigid materials with limited deformation capabilities, lacking adaptability. After prolonged use, structural deformation can lead to squeegee failure. Furthermore, because they are often integrated into the cleaning equipment, they typically require professional repair, significantly impacting the user experience.

[0004] Therefore, it is necessary to provide an air pump-driven auxiliary cleaning scraper and a method of use to solve the above problems. Summary of the Invention

[0005] To address the aforementioned problems, the present invention aims to provide an air pump-driven auxiliary cleaning scraper and its usage method. The air pump inflates or deflates the scraper assembly within a closed space, providing sufficient rigidity while preventing hard impacts and protecting the structure. By simply installing it on the outside of the cleaning equipment, the scraper assembly does not interfere with the equipment during operation and also offers better maintainability. A visual sensor monitors the distance to the wall in real time and predicts blind spots, allowing the rubber scraper to accurately and timely conform to the surface to be cleaned, thus solving the problem of blind spots present in traditional cleaning devices.

[0006] To achieve the above objectives, the present invention provides an air pump-driven auxiliary cleaning scraper assembly and a method of use, comprising: a cleaning device, a fixed guide rail, an upper mounting part, and a scraper assembly. The fixed guide rail is fixed to the outside of the cleaning device by a base plate. The upper mounting part is connected to the fixed guide rail by inserting a support leg into the hollow part of a U-shaped locking block. The scraper assembly is connected to the upper mounting part by bolting one end of an electric push rod to the side panel.

[0007] The upper mounting part includes: a structural body, a vision sensor mounted on the front surface of the structural body, inner mounting parts mounted on both sides of the structural body, side mounting parts connected to the inner mounting parts via round tubes, the side mounting parts located on the outside of the structural body, an adjustment knob mounted between the side mounting parts and the structural body, the adjustment knob being able to adjust the distance between the side mounting parts and the structural body, and a support leg mounted on the lower surface of the side mounting parts.

[0008] The fixed guide rail includes: a base plate, a quadrilateral locking block, and a fixing block. The upper part of the base plate is provided with an upper locking groove, and the lower part of the base plate is provided with a lower locking groove. Rubber blocks are arranged at equal intervals between the lower locking groove and the upper locking groove. The bottom end of the lower locking groove has a lower groove arranged parallel to the length of the lower locking groove. The quadrilateral locking block can be locked between the lower locking groove and the upper locking groove. The lower end of the quadrilateral locking block is provided with a locking groove. The contact surface between the quadrilateral locking block and the base plate is provided with a groove that can fit with the rubber blocks. An installation plate is installed on the outer surface of the quadrilateral locking block. A first installation part is installed on the outer surface of the installation plate. A spring is coaxially arranged in the first installation part. Locking blocks are provided at both ends of the spring. The locking blocks can slide along the compression direction of the spring. The locking blocks are U-shaped and have a locking groove inside. The upper surface of the fixing block is provided with a protruding edge that can fit with the lower groove. The upper surface of the fixing block is provided with a buckle that can be locked into the locking groove.

[0009] A drive motor is installed inside the main structure and is located at the front end of the inner mounting part. A bearing is installed on the outer surface of the main structure and is located at the front end of the outer mounting part. A transmission shaft is coaxially arranged on the bearing. One end of the transmission shaft is connected to the drive motor via a transmission belt, and the other end is connected to an electric push rod. An air pump is installed inside the main structure and is located in front of the drive motor. The air pump is connected to a vent pipe.

[0010] The scraper assembly includes a front panel and a rear panel. A side panel is installed between the front panel and the rear panel, and the side panel is located at both ends of the front panel. An upper mounting plate is installed between the front panel and the rear panel, and the upper mounting plate is located above the front panel. The front panel, rear panel, upper mounting plate, and side panel form a box with an opening facing downwards. A pivot seat is installed below the front panel, and the pivot seats are evenly spaced along the length of the front panel. A pivot is coaxially arranged between the pivot seats. An L-shaped mounting plate is installed below the pivot, and a rubber scraper is installed at the lower end of the L-shaped mounting plate. The upper end of the L-shaped mounting plate is located between the front panel and the rear panel. A limit plate is installed on the outer surface where the L-shaped mounting plate intersects with the pivot, and the upwardly extending end of the limit plate can contact the front panel.

[0011] The box body, consisting of the front panel, rear panel, upper mounting plate, and side panel, has fan-shaped folded paper surfaces at both ends. The fan-shaped folded paper surfaces are arranged parallel to the side panels. One end of the fan-shaped folded paper surface is mounted on the front panel along the unfolding direction, and the other end is mounted on the inner surface of the upper part of the L-shaped mounting plate. The edges of the unfolded fan-shaped surfaces A and B are connected to rectangular folded paper surfaces. A vent pipe is provided on the surface of the fan-shaped folded paper surfaces. The rectangular folded paper surfaces, the unfolded fan-shaped surfaces, the front panel, and the upper part of the L-shaped mounting plate form a closed space, which can be inflated by the vent pipe.

[0012] When the rectangular folded paper surface is connected to the edge of the fan-shaped unfolded surface A, the side length L1 should be equal to L3.

[0013] When the rectangular folded surface is connected to the edge of the fan-shaped unfolded surface B, the side length L2 should be equal to L3.

[0014] The L-shaped mounting plate can be rotated around the pivot mounting axis in the unfolding direction of the fan-shaped folded paper surface.

[0015] The support leg is provided with a protrusion that can be engaged with the slot.

[0016] The method of using the air pump driven auxiliary cleaning scraper assembly includes the following steps:

[0017] Step a: When using the cleaning equipment, when the vision sensor detects obstacles such as walls in front, the electric push rod adjusts the extension distance, the air pump starts, and the air pump uses the air pipe to inflate the enclosed space formed by the rectangular folded surface, the fan-shaped unfolded surface, the front panel and the upper surface of the L-shaped mounting plate. The fan-shaped unfolded surface unfolds and pushes the L-shaped mounting plate to rotate around the rotating shaft mounting axis until the limit plate contacts the front panel. At this time, the rubber scraper contacts the surface to be cleaned.

[0018] Step b: When the vision sensor detects that obstacles such as the wall in front have disappeared, the air pump starts in reverse. The air pump uses the air pipe to draw air into the closed space formed by the rectangular folded surface, the fan-shaped unfolded surface, the front panel and the upper surface of the L-shaped mounting plate. The fan-shaped unfolded surface retracts and drives the L-shaped mounting plate to rotate in the opposite direction around the rotating shaft mounting axis. At this time, the limiting plate separates from the front panel, and the rubber scraper disengages from the surface to be cleaned.

[0019] Compared with related technologies, the beneficial effects of the present invention are as follows:

[0020] (1) The visual sensor can monitor the distance to the wall in real time and predict the location of the dead corner, so that the mechanism can respond in advance according to the forward speed, ensuring that the rubber scraper can accurately fit the surface to be cleaned in a timely manner, thus solving the dead corner problem of traditional cleaning devices;

[0021] (2) The air pump can inflate or depress air into the enclosed space formed by the rectangular folded paper surface, the fan-shaped unfolded surface, the front panel and the upper surface of the L-shaped mounting plate, thereby driving the L-shaped mounting plate to rotate around the axis of the rotating shaft. This process is different from the traditional rigid mechanical arm structure, realizing physical buffering, preventing hard impact and protecting the mechanism and the wall, and can also better adapt to different cleaning surfaces.

[0022] (3) The quadrilateral block and the support leg have a certain adjustment capability, which enables the device to adapt to various types of cleaning equipment and has better compatibility than traditional devices;

[0023] (4) This invention is attached to the outside of the cleaning equipment and is independent of the cleaning equipment itself. It can work without interfering with the cleaning equipment, which solves the problem of poor stability of the complex mechanical structure of traditional devices, and also has better maintainability.

An upper mounting plate 405 is installed between the front panel 401 and the rear panel 403, and the upper mounting plate 405 is located above the front panel 401. The front panel 401, rear panel 403, upper mounting plate 405, and side panel 402 form a box with an opening facing downwards. A pivot seat 406 is installed below the front panel 401. The pivot seats 406 are evenly spaced along the length of the front panel 401. A pivot 412 is coaxially arranged between the pivot seats 406.

The L-shaped mounting plate 408 can rotate around the mounting axis of the pivot 412 along the unfolding direction of the fan-shaped folding surface 410.

[0041] like Figure 7 As shown, the box body consisting of the front panel 401, rear panel 403, upper mounting plate 405, and side panel 402 has fan-shaped folding surfaces 410 at both ends.

[0043] A method of using an air pump-driven auxiliary cleaning scraper assembly, such as... Figure 1-9 As shown, it includes the following steps:

[0044] Step a: When using the cleaning equipment, when the vision sensor 302 detects obstacles such as walls in front, the electric push rod 313 adjusts the pushing distance, the air pump 310 starts, and the air pump 310 uses the air pipe 314 to inflate the closed space formed by the rectangular folded paper surface 411, the fan-shaped unfolding surface 410, the front panel 401 and the upper surface of the L-shaped mounting plate 408. The fan-shaped unfolding surface 410 unfolds and pushes the L-shaped mounting plate 408 to rotate around the mounting axis of the rotating shaft 412 until the limiting plate 409 contacts the front panel 401. At this time, the rubber scraper 407 contacts the surface to be cleaned.

[0045] Step b: When the vision sensor 302 detects that obstacles such as the wall in front have disappeared, the air pump 310 starts in reverse. The air pump 310 uses the air pipe 314 to draw air into the closed space formed by the rectangular folded paper surface 411, the fan-shaped unfolded surface 410, the front panel 401 and the upper surface of the L-shaped mounting plate 408. The fan-shaped unfolded surface 410 retracts and drives the L-shaped mounting plate 408 to rotate in the opposite direction around the mounting axis of the rotating shaft 412. At this time, the limiting plate 409 separates from the front panel 401, and the rubber scraper 407 disengages from the surface to be cleaned.

The fan-shaped unfolded surface (410) unfolds and pushes the L-shaped mounting plate (408) to rotate around the mounting axis of the rotating shaft (412) until the limiting plate (409) contacts the front panel (401). At this time, the rubber scraper (407) contacts the surface to be cleaned. Step b: When the vision sensor (302) detects that the obstacles such as the wall in front have disappeared, the air pump (310) starts in reverse. The air pump (310) uses the air pipe (314) to draw air into the closed space formed by the rectangular folded paper surface (411), the fan-shaped unfolded surface (410), the front panel (401) and the upper surface of the L-shaped mounting plate (408). The fan-shaped unfolded surface (410) retracts and drives the L-shaped mounting plate (408) to rotate in the opposite direction along the mounting axis of the rotating shaft (412). At this time, the limiting plate (409) separates from the front panel (401), and the rubber scraper (407) disengages from the surface to be cleaned.
