Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cleaning equipment, in particular to a scraping strip assembly and a scrubber. BACKGROUND

[0002] The scrubber generally sets a scraping strip at the rear end of the rolling brush. When pushing forward, the scraping strip can scrape the dirt left on the ground. However, in actual use, the user will repeatedly push and pull forward and backward, so that the dirt left on the ground cannot be effectively scraped when pulling backward.

[0003] In the related art, some scrubbers are provided with a scraping strip at the front end. The scraping strip runs up and down. However, due to the arc-shaped appearance of the front end of the top cover, the stroke of the scraping strip in up and down movement is limited. When there is a larger particle at the front end that needs to be cleaned, the front end of the scraping strip is raised, and the height from the ground is very small, which can push away the particle, so that the particle cannot be twisted into the rolling brush and sucked away.

Therefore, within the limited height range of the floor scrubber, the squeegee assembly can increase the lifting height of the squeegee, resulting in a higher height off the ground after it rises, which helps reduce the probability that particles are pushed away and cannot be caught and sucked up by the roller brush.

If present, the terms "vertical", "horizontal", "up", "down", "left", "right" and similar expressions used in the present application are only for illustrative purposes and do not represent the only implementation.

[0042] As described in the background, in the related art, the up-down lifting direction of the front squeegee is equivalent to the height direction of the scrubber 200. Therefore, due to the height of the scrubber 200 at the front end, the lifting stroke of the front squeegee is also very limited, which leads to the problem of insufficient ground clearance after the squeegee is lifted. In addition, the structure for lifting the front squeegee in the related art is also relatively complex, and is inconvenient to disassemble and clean.

[0043] Please refer to Figures 1 to 5 The squeegee assembly 100 provided by an embodiment of the present application includes a squeegee body 10 and a driving mechanism 30. The squeegee body 10 includes a hard part 11 and a squeegee part 13. The squeegee body 10 includes the hard part 11 and the squeegee part 13. The hard part 11 is configured to be able to rotate around a first direction, and during the rotation of the hard part 11, the first end 111 thereof is lifted in the height direction of the scrubber 200. The squeegee part 13 is connected to the first end 111. The driving mechanism 30 is in transmission cooperation with the hard part 11 and is configured to be able to drive the hard part 11 to rotate.

[0044] In an embodiment, the squeegee assembly 100 is used in the scrubber 200, and in particular, can be used as the front squeegee of the scrubber 200. In other embodiments, the squeegee assembly 100 can also be used in a sweeper, a scrubbing and decontamination integrated machine, etc., which is not specifically limited here.

[0045] The hard part 11 is made of a material with high compression resistance and strength, and is not easy to deform or break, and has good driving capacity, and can respond in time and move accordingly under the driving of the driving mechanism 30. The hard part 11 can be, but is not limited to, a hard rubber material, such as high styrene rubber or polystyrene, ABS plastic, polyvinyl chloride, etc. Herein, no specific limitation is made. The scraping strip part 13 is used for direct contact and cleaning of the ground, and is made of a soft material to fit the ground for cleaning work. The scraping strip part 13 can be, but is not limited to, a soft rubber material, such as natural rubber, synthetic rubber, polypropylene, polyethylene, silicone, etc. Herein, no specific limitation is made.

[0046] It can be understood that the first direction (such as Figure 1 the direction perpendicular to the paper surface and the X direction in Figure 6 the X direction) intersects the height direction of the scrubber 200, wherein the height direction of the scrubber 200 is perpendicular to the horizontal plane. For ease of understanding, the following embodiments are described with the first direction parallel to the horizontal plane as an example.

[0047] The hard part 11 can rotate around the first direction under the driving of the driving mechanism 30, and the first end 111 thereof can be raised and lowered. Correspondingly, the scraping strip part 13 connected to the first end 111 of the hard part 11 is also raised and lowered, and the scraping strip body 10 has a ground clearance state in which the scraping strip part 13 is away from the ground and a working state in which the scraping strip part 13 is attached to the ground.

[0048] The scraping strip assembly 100 drives the hard part 11 to rotate through the driving mechanism 30, and then drives the scraping strip part 13 to raise and lower, thereby realizing the switching between the ground clearance and the ground attachment. In other words, the lifting action of the scraping strip part 13 can be converted into a rotating action, and the distance of the partial lifting is decomposed into horizontal displacement by the rotating action. Therefore, within the limited height dimension of the scrubber 200, the scraping strip assembly 100 can improve the lifting height of the scraping strip part 13, so that the ground clearance height after lifting is higher, which helps to reduce the probability that the particles are pushed away and cannot be twisted into the suction by the roller brush 210.

[0049] In some embodiments, the hard part 11 and the scraping strip part 13 are integrally formed. It can be understood that the hard part 11 and the scraping strip part 13 can be integrally injection molded at the molding stage, or can be integrally formed by secondary injection molding, etc.

[0050] In this way, the hard part 11 and the scraping strip part 13 are closely connected. In addition, there is no connection gap between the hard part 11 and the scraping strip part 13 to prevent dust and particles from being taken in.

[0051] In some embodiments, the rigid part 11 is arc-shaped around a first axis, and the first axis is parallel to the first direction, the rigid part 11 is configured to be rotatable around the first axis, and the first end 111 is one end of the rigid part 11 in the circumferential direction of the rigid part 11 around the first axis.

[0052] It can be understood that the rigid part 11 can be generally regarded as a part of a cylindrical structure, and the first axis is the axis of the cylindrical structure.

[0053] In this way, the rotation of the rigid part 11 is more stable, and the required rotation space is smaller. In addition, the rotation of the rigid part 11 can be more effectively converted into the displacement of the blade part 13 connected to the first end 111 of the rigid part 11.

[0054] In some embodiments, when the rigid part 11 is rotated around the first direction in a first direction, the first end 111 rises, and when the rigid part 11 is rotated around the first direction in a second direction, the first end 111 descends.

[0055] The driving mechanism 30 includes a driver 31 and an elastic member 33, both of which are matched with the rigid part 11, and the driver 31 is configured to provide a driving force for driving the rigid part 11 to rotate in the first direction, and the elastic member 33 is configured to provide a driving force for driving the rigid part 11 to rotate in the second direction. It can be understood that the driver 31 can be but not limited to a motor, and the elastic member 33 can be but not limited to a spring.

[0056] In this way, when the driver 31 is not started, the rigid part 11 can be rotated to the ground under the action of the elastic member 33, so that the blade body 10 is in a working state, that is, the working state of the blade body 10 is its initial state. At this time, the blade body 10 can clean the ground through the blade part 13. After the driver 31 is started, the rigid part 11 can be rotated to the ground under the driving of the driver 31, so that the blade body 10 is in a ground clearance state. At this time, a sufficient gap is formed between the blade body 10 and the ground, so that particles can pass through and be twisted into the roller brush 210.

[0057] Please refer to Figures 6 to 10 In some embodiments, the blade assembly 100 further includes a cover structure 50, the cover structure 50 has a sandwich layer 51 and an extension outlet 52, the sandwich layer 51 has an arc-shaped part 511, and the arc-shaped part 511 is arranged around the first direction. The rigid part 11 is configured to be at least partially located in the sandwich layer 51 and can slide along the arc-shaped part 511. The extension outlet 52 is located at one end of the arc-shaped part 511 in the circumferential direction of the arc-shaped part 511 around the first direction, and is connected between the inside and outside of the sandwich layer 51, and the blade body 10 can be extended and retracted outward from the extension outlet 52.

[0058] In other words, the hard part 11 is at least partially located in the interlayer 51, and the sliding along the arc-shaped part 511 of the interlayer 51 realizes the rotation around the first direction. The squeegee part 13 is at least partially capable of extending from the extension opening 52, and the extension and retraction are realized along with the rotation of the hard part 11.

[0059] In this way, the hard part 11 can stably rotate around the first direction, and the structure for realizing the rotation is simple and requires fewer parts. At the same time, the squeegee part can normally extend and retract through the extension opening 52 of the upper cover structure 50 to meet the needs of switching the state of the squeegee body.

[0060] Further, the arc-shaped part 511 is arranged around the circumferential side of the rolling brush 210 of the scrubber 200, and the extension opening 52 is arranged on the front side of the rolling brush 210 and downward.

[0061] It can be understood that the first direction is parallel to the axis of the rolling brush 210, the hard part 11, the arc-shaped part 511, and the rolling brush 210 can be coaxially arranged, and the first axis is the rotation axis of the rolling brush 210. The front side of the rolling brush 210 is the front side in the front-rear direction of the scrubber 200 when in use.

[0062] In this way, as the front squeegee of the scrubber 200, the squeegee body 10 can lift and lower the squeegee part up and down from the extension opening 52 to realize the lifting and lowering when the hard part 11 rotates.

[0063] Further, the squeegee body 10 further comprises a rolling member 15, the rolling member 15 is arranged on the hard part 11, and the hard part 11 slides along the arc-shaped part 511 through the rolling member 15.

[0064] It can be understood that the rolling member 15 can be a ball, a roller, or the like, and the hard part 11 can contact the inner wall of the interlayer 51 through the rolling member 15.

[0065] In this way, the rolling member 15 can reduce the surface of the hard part 11 and the inner wall of the interlayer 51, and further make the sliding along the arc-shaped part 511 more smooth.

[0066] In some embodiments, the upper cover structure 50 comprises a top cover 53 and an inner cover 54, the top cover 53 and the inner cover 54 are connected and spaced to form the interlayer 51, and the inner cover 54 has a water storage cavity 541 and a water adding position 543.

[0067] Among them, the top cover 53 can be part of the shell of the scrubber 200, and the inner cover 54 is below the top cover 53 and in the shell of the scrubber 200. The top cover 53 and the inner cover 54 are at least partially spaced to form the interlayer 51, that is, the squeegee body 10 is arranged between the top cover 53 and the inner cover 54 and can slide along the surface of at least one of them towards the other.

[0068] The inner cover 54 is concave to form a water storage cavity 541, which can be used as a clean water tank to store clean water. The water filling position 543 is used to fill clean water into the water storage cavity 541.

[0069] In this way, the upper cover mechanism for moving the squeegee body 10 is integrated with the water storage cavity 541 as a clean water tank, which can simplify the structure of the scrubber 200 and help reduce the number of parts.

[0070] Further, the upper cover structure 50 has a positioning and matching structure, and is detachably connected to the lower cover structure 220 of the scrubber 200 through the positioning and matching structure.

[0071] Specifically, the positioning and matching structure includes a first buckle 551 and a joint 552. The lower cover structure 220 has a second buckle 221 matched with the first buckle 551 and a butt joint hole 222 matched with the joint 552. The lower cover structure 220 is part of the shell of the scrubber 200.

[0072] In this way, the squeegee body 10 is mounted on the upper cover structure 50 and can be detached together with the upper cover mechanism from the lower cover structure 220 of the scrubber 200, so as to wash the squeegee body 10 and the upper cover structure 50.

[0073] In some embodiments, the driving mechanism 30 further includes a sliding block 35 matched with the hard part 11. The upper cover structure 50 has a sliding groove 531, and the sliding block 35 is configured to be able to slide along the sliding groove 531. The driver 31 is drivingly connected to the sliding block 35 and is configured to be able to drive the hard part 11 to slide along the arc-shaped part 511 by driving the sliding block 35.

[0074] The squeegee body 10, the elastic member 33 and the sliding block 35 are arranged in the interlayer 51 of the upper cover structure 50, and the top cover 53 forms the sliding groove 531 for guiding the sliding of the sliding block 35.

[0075] In this way, the driver 31 can drive the hard part 11 to rotate through the sliding block 35 under the guidance of the sliding groove 531.

[0076] Further, the sliding block 35 is configured to be able to move in a second direction (e.g. the Y direction as shown) under the driving of the driver 31. The sliding block 35 has a matching groove 351, and the hard part 11 has a matching shaft 113 arranged in the matching groove 351 and configured to be able to rotate in a first direction and move in a third direction (e.g. the Z direction as shown) in the matching groove 351. Figure 1 Figure 1 The first direction, the second direction and the third direction intersect with each other.

[0077] ​It can be understood that the sliding groove 531 extends along the second direction. The first direction, the second direction and the third direction can be perpendicular to each other, and the third direction is a vertical direction, wherein the second direction corresponds to the front-rear direction of the scrubber 200, and the third direction corresponds to the height direction of the scrubber 200.

[0078] The matching shaft 113 can be located at the second end 115 of the hard part 11, and the second end 115 is the other end opposite to the first end 111 in the first direction.

[0079] In this way, the rotation of the hard part 11 around the first direction can be decomposed into its movement along the second direction and the third direction at the matching shaft 113, and then the driving of the hard part 11 is realized by driving the slider 35 to translate along the second direction through the driver 31.

[0080] Further, the slider 35 also has a cam groove 353, and the driving mechanism 30 further includes a cam 37 arranged in the cam groove 353, and the driver 31 is in transmission connection with the cam 37 and is configured to be able to drive the cam 37 to rotate to drive the slider 35 to move through the cam groove 353.

[0081] The cam 37 and the driver 31 can be mounted on the lower cover structure 220, and the upper cover structure 50 can have an assembly position 545 assembled with the cam 37, so that the cam 37 can pass through the assembly position 545 and cooperate with the slider 35. The cam 37 can have a linkage state of abutting against the groove wall of the cam groove 353 and a linkage disconnection state of being separated from the groove wall, and in the linkage state, the rotation of the cam 37 can drive the slider 35 to move in the sliding groove 531 through the external force applied by the groove wall, and in the non-linkage state, the squeegee body 10 returns to the initial state under the driving of the elastic member 33. In addition, the groove wall of the cam groove 353 abutting against the cam 37 in the linkage state can be arranged to be inclined relative to the second direction.

[0082] It can be understood that the rotation axis of the cam 37 is perpendicular to the second direction, and when the cam 37 rotates to the linkage state and contacts the groove wall of the cam groove 353, the position of the contact between the cam 37 and the groove wall of the cam groove 353 relative to the rotation axis of the cam 37 in the second direction changes constantly when the cam 37 continues to rotate, thereby pushing the slider 35 to slide in the second direction.

[0083] In this way, the driver 31 can drive the cam 37 to rotate to push the slider 35 to slide in the second direction, and then realize the continuous and stable driving of the hard part 11 through the slider 35.

[0084] In some embodiments, the first end 111 has a first position and a second position in the height direction. The hard part 11 has a first limiting structure 117 configured to limit the first end 111 to be in the first position (e.g. Figure 1When the first end 111 is in the second position (as shown), a limit is generated to block the first end 111 from descending in the height direction; and / or, the hard part 11 has a second limit structure 118 configured to generate a limit to block the first end 111 from ascending in the height direction when the first end 111 is in the second position (as shown). Figure 2 When the first end 111 is in the second position (as shown), a limit is generated to block the first end 111 from descending in the height direction; and / or, the hard part 11 has a second limit structure 118 configured to generate a limit to block the first end 111 from ascending in the height direction when the first end 111 is in the second position (as shown).

[0085] It can be understood that when the first end 111 is in the first position, the wiper body 10 is in a working state in which the wiper part 13 is in contact with the ground, and when the first end 111 is in the second position, the wiper body 10 is in a ground-leaving state in which the wiper part 13 is away from the ground, and at this time, the position of the wiper part 13 reaches the highest.

[0086] Specifically, the first limit structure 117 abuts against the inner edge of the limit boss 533 at the extension opening 52 when the first end 111 is in the first position, and the second limit structure 118 abuts against the outer edge of the limit boss 533 at the extension opening 52 when the first end 111 is in the second position. The first limit structure 117 can be a limit rib.

[0087] In this way, the lifting range of the first end 111 is determined by the limits of the first limit structure 117 and the second limit structure 118.

[0088] For ease of understanding, the installation process of the wiper assembly 100 is briefly described as follows:

[0089] The hard part 11 and the wiper part 13 of the wiper body 10 can be an integral molded part. During installation, the wiper body 10 is first installed on the top cover 53, then the spring as the elastic member 33 is installed, one end of the spring abutting against the wiper body 10 and the other end abutting against the top cover 53. Then the slider 35 is installed, one end of the slider 35 having a matching groove 351 and being used for clamping into the matching shaft 113 of the hard part 11, and the other end of the slider 35 being installed in the sliding groove 531 of the top cover 53. Finally, the inner cover 54 is closed, and the inner cover 54 is provided with the water storage cavity 541 and the water filling position 543. After the upper cover structure 50 is assembled, the wiper body 10 is in the extended state by default under the action of the spring, that is, the wiper part 13 is lowered to the ground-contacting position. The driver 31 and the cam 37 are both assembled in the lower cover structure 220, and when the upper cover structure 50 is installed to the lower cover structure 220, the cam 37 is clamped into the cam groove 353 of the slider 35. For ease of assembly, the cam 37 is in a default state with a gap from the cam groove 353, and does not produce linkage, and only rotates to link when the driver 31 is powered. At the same time, the upper cover structure 50 is provided with a buckle position and a joint 552, which are respectively fixedly matched with the buckle position and the counterbore 222 of the counter-coupled lower cover structure 220, so as to finally realize the detachable fixing of the upper cover structure 50 and the lower cover structure 220, and facilitate disassembly and assembly.

[0090] The scraper assembly 100 is integrated into the detachable upper cover structure 50 as the scraper body 10 of the front scraper and the water storage cavity 541 of the water tank, so that the user can complete the cleaning of the scraper and water adding at one time without separate processing, thereby greatly improving the user experience.

[0091] Specifically, the working process of the scraper assembly 100 is generally as follows: when the roller brush 210 advances, the driver 31 starts to rotate, drives the slider 35 to move horizontally backward through the cam 37, thereby pulling the hard part 11 to rotate clockwise and pulling the scraper part 13 to rise, the rising height h is between 10 mm and the diameter of the roller brush 210 (i.e. 2 times the line distance from the ground to the axis of the roller brush 210), so as to achieve a greater lifting height and avoid the problem that large particles cannot be twisted into the roller brush 210 because they are pushed away by the scraper; when the roller brush 210 retreats, the driver 31 returns to the initial state, at this time, the cam 37 does not effectively push the slider 35, and the slider 35 is in a disconnected state. At the same time, the hard part 11 rotates counterclockwise under the action of the spring, pulls the slider 35 to move horizontally forward, and when the first limiting structure 117 on the scraper body 10 abuts against the limiting boss 533 of the top cover 53 structure at the outlet 52, the scraper part 13 touches the ground, thereby solving the problem of residual dirt on the ground when the roller brush 210 retreats and improving the cleaning efficiency.

[0092] In this way, the scraper assembly 100 can effectively solve the problem of insufficient movement of the scraper part 13, achieve the cleaning effect of large particles, and has a simple structure, fewer components, low cost, and an integrated detachable structure with the water storage cavity 541 of the water tank, which is convenient to clean and greatly improves the user experience. Specifically, 1, when advancing, the scraper part 13 rises, solving the problem of insufficient movement of the scraper part 13 and the problem that large particles cannot be twisted into the roller brush 210. 2, when retreating, the scraper part 13 descends to touch the ground, solving the problem of residual dirt on the ground when the roller brush 210 retreats and improving the cleaning efficiency. 3, the scraper body 10 is connected with the upper cover structure 50 having the water storage cavity 541 and can be disassembled together, which is convenient to clean and improves the user experience.

[0093] The application also provides a scrubber 200 comprising the scraper assembly 100.
