Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of a water blocking system of a scrubber, and in particular to a lifting water blocking system and a scrubber using the same. BACKGROUND

[0002] As an important cleaning device, a scrubber is widely used in commercial, industrial and household fields. The core function of the scrubber is to realize efficient cleaning and sewage collection of the ground through the cooperation of a brush assembly and a water blocking assembly.

[0003] The sewage collection mode of the scrubbing brush of the existing scrubber is that the scrubbing brush has a water blocking plate, and the water blocking plate blocks the sewage and then transmits the sewage to the rear water absorbing scraper to be collected by the water absorbing scraper. However, the water blocking plate is usually a fixed structure, and needs to be adjusted regularly according to the wear condition of the scrubbing brush. The adjustment effect of the water blocking plate is also affected by the experience of the operator: if the water blocking rubber is not pressed enough, the water scraping effect is poor; if the water blocking rubber is pressed too much, not only the water scraping effect is poor, but also the water blocking rubber is easy to be rolled under the scrubbing disc and accelerate the wear. SUMMARY

[0004] In order to overcome the above-mentioned problems, the present application provides a lifting water blocking system and a scrubber using the same.

[0005] In a first aspect, the lifting water blocking system provided by the present application adopts the following technical solution:

[0006] The lifting water blocking system comprises a brush disc holder, two water blocking frames symmetrically arranged on both sides of the brush disc holder, a connecting rod assembly connected to each water blocking frame, a water blocking assembly connected to the end of the connecting rod assembly away from the water blocking frame, an elastic member connected between the connecting rod assembly and the water blocking assembly, and a limiting member arranged on the water blocking frame for limiting the connecting rod assembly. The water blocking assembly is connected to the water blocking frame through the connecting rod assembly to form a parallelogram structure, so that the connecting rod assembly can drive the water blocking assembly to swing towards or away from the water blocking frame. The elastic member is used to pull the water blocking assembly to move away from the water blocking frame to provide a downward pressure for the water blocking assembly. The limiting member is used to limit the swing range of the connecting rod assembly. The water blocking part of the water blocking assembly is turned outward at a predetermined angle.

[0007] By adopting the technical scheme, the water blocking assembly, the connecting rod assembly and the water blocking frame form a parallelogram structure, so that the connecting rod assembly can drive the water blocking assembly to swing towards the direction of approaching or moving away from the water blocking frame, thereby realizing the position adjustment function of the water blocking assembly; the elastic member pulls the water blocking assembly to move away from the water blocking frame, thereby providing stable downward pressure for the water blocking assembly, ensuring the contact effect of the water blocking assembly with the ground; the limiting member limits the swing range of the connecting rod assembly, effectively reducing the risk of structural failure caused by excessive swing of the water blocking assembly; the water blocking part of the water blocking assembly is outwardly turned at a predetermined angle, improving the wiping effect and reducing the risk of the water blocking part being rolled into the area below the floor cleaning brush, thereby improving the sewage collection efficiency and cleaning effect.

[0008] Optionally, one end of the water blocking frame is hinged to the brush disc frame, and the other end of the water blocking frame is locked to the brush disc frame.

[0009] By adopting the technical scheme, one end of the water blocking frame is hinged to the brush disc frame, so that the water blocking frame can be flipped relative to the brush disc frame, thereby facilitating cleaning and maintenance of the area between the brush disc frame and the water blocking frame when needed; the other end of the water blocking frame is locked to the brush disc frame, ensuring that the water blocking frame can be stably fixed to the brush disc frame during operation, effectively reducing the risk of loosening or flipping of the water blocking frame caused by external force, thereby ensuring the stability and reliability of the water blocking assembly and improving the cleaning effect and operation stability of the overall system.

[0010] Optionally, the connecting rod assembly comprises first and second connecting rods arranged in parallel to each other, the top ends of the first and second connecting rods are hinged to one side of the water blocking frame close to the brush disc frame, the bottom ends of the first and second connecting rods are hinged to the water blocking assembly, and the first and second connecting rods can drive the water blocking assembly to swing towards the direction of approaching or moving away from the water blocking frame.

[0011] By adopting the technical scheme, the first and second connecting rods are arranged in parallel to each other and are respectively hinged to the water blocking frame and the water blocking assembly, forming a parallelogram structure; this structure enables the connecting rod assembly to drive the water blocking assembly to swing towards the direction of approaching or moving away from the water blocking frame, thereby realizing flexible adjustment of the position of the water blocking assembly; this design not only improves the adaptability of the water blocking assembly, but also ensures stable operation of the water blocking assembly under different working conditions, thereby improving the reliability of the overall system.

[0012] Optionally, the water blocking assembly comprises a water blocking plate hinged to the first and second connecting rods, a pressing strip detachably connected to the water blocking plate, and a water blocking rubber strip clamped between the water blocking plate and the pressing strip, and the bottom surface of the water blocking plate is formed with an outward turning part outwardly turned at a predetermined angle.

[0013] By adopting the technical scheme, the water blocking assembly is composed of a water blocking plate, a pressing strip and a water blocking rubber strip, the water blocking plate is hinged with the first connecting rod and the second connecting rod, so that the water blocking assembly can move with the swinging of the connecting rod assembly; the water blocking rubber strip between the water blocking plate and the pressing strip plays an actual water blocking role, and the everted part formed on the bottom surface of the water blocking plate makes the part of the water blocking rubber strip in contact with the ground evert at a predetermined angle, so that the best water wiping effect is maintained, the possibility of the water blocking rubber strip being rolled into the scrubbing brush is effectively reduced, and the sewage collection efficiency and the cleaning effect are improved.

[0014] Optionally, the rear end of the water blocking plate and the rear end of the pressing strip are both formed with a bending part bent towards the direction close to the brush disc holder, and the bending parts on both sides of the brush disc holder form a closing structure.

[0015] By adopting the technical scheme, the setting of the bending part enables the water blocking assemblies on both sides of the brush disc holder to effectively converge the sewage during work, forming a closing structure, so that the sewage collection efficiency is improved, and the sewage overflow is minimized.

[0016] Optionally, a guide wheel is installed on the side end of the water blocking plate close to the brush disc holder.

[0017] By adopting the technical scheme, the setting of the guide wheel enables the maximum pressing amount of the water blocking rubber strip to be limited when the water blocking rubber strip contacts the ground and is subjected to pressure, so that the water blocking rubber strip can maintain the best pressing angle; during the movement of the brush disc holder to the rear, the friction between the water blocking rubber strip and the ground can cause the connecting rod assembly to tend to swing downward, thereby hindering the movement of the brush disc holder; at this time, the guide wheel effectively offsets the swinging tendency of the connecting rod assembly by rolling, ensuring the smooth operation of the equipment and improving the overall cleaning efficiency and stability.

[0018] Optionally, an adjusting assembly for adjusting the limiting piece is arranged on the water blocking holder.

[0019] By adopting the technical scheme, the adjusting assembly can change the relative position of the limiting piece and the connecting rod assembly, so as to control the swinging range of the connecting rod assembly; the adjustability enables the water blocking assembly to stably operate under different working conditions, effectively reduces the problems of reduced water wiping effect or unstable structure caused by excessive swinging of the connecting rod assembly, and thus improves the adaptability and reliability of the entire lifting water blocking system.

[0020] Optionally, the elastic member is a tension spring, the bottom end of the second connecting rod is formed with an extension part, one end of the tension spring is hooked to the extension part, a fixed block is fixedly connected to the side of the water blocking plate away from the water blocking rubber strip, and the other end of the tension spring away from the extension part is hooked to the fixed block.

[0021] By adopting the above technical solution, the tension spring, as an elastic element, can continuously provide stable tension, pulling the baffle plate away from the baffle frame, thereby providing reliable downward pressure to the baffle strip. Specifically, one end of the tension spring is hooked onto the extension at the bottom of the second connecting rod, and the other end is hooked onto a fixing block on the side of the baffle plate away from the baffle strip. This connection method ensures the stable transmission of the tension spring force, allowing the baffle strip to fit tightly against the ground and enhance the wiping effect. At the same time, this design can also automatically adapt to the wear of the floor scrubber, always maintaining the baffle strip in its optimal working condition, further improving wastewater collection efficiency and cleaning effect.

[0022] Optionally, the water-blocking rubber strip has multiple equally spaced adjustment ports located on the same vertical line, and the side of the water-blocking plate near the water-blocking rubber strip is formed with a plug-in block that engages with the adjustment ports.

[0023] By adopting the above technical solution, multiple equally spaced adjustment ports located on the same vertical line cooperate with the plug blocks on the water baffle to fix the water baffle strip at different height positions, thereby adjusting the height of the water baffle strip according to actual use needs to adapt to different ground environments or cleaning requirements.

[0024] Secondly, this application provides a floor scrubber using a lifting water baffle system, including a floor scrubber body and a squeegee disposed on the bottom surface of the floor scrubber body and located on the rear side of the floor scrubber body, the squeegee being used to collect wastewater behind the baffle of the front water baffle component.

[0025] By adopting the above technical solution, the floor scrubber utilizes a lifting and water-blocking system to effectively block and collect wastewater.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1.

A plurality of water passing openings 124 are formed on the mounting seat 122, which are equally spaced and vertically penetrate the mounting seat 122, and the water supply end of the water supply assembly supplies water to the floor brush 121 through the water passing openings 124.

[0045] Referring to Figure 3 and Figure 5 , the water supply assembly comprises a water suction pump 13 installed on the top surface of the brush disc holder 1, a water suction pipe 131 fixedly connected with the water inlet end of the water suction pump 13, a three-way pipe 132 fixedly connected with the water outlet end of the water suction pump 13, and two water inlet pipes 133 respectively connected with the three-way pipe 132; a water tank (not shown in the figure) is installed on the top surface of the brush disc holder 1, one end of the water suction pipe 131 away from the water suction pump 13 extends to the inner bottom wall of the water tank, so as to supply water to the water suction pipe 131 through the water tank; the two water inlet pipes 133 are fixedly connected with the other two interfaces of the three-way pipe 132, and one end of the water inlet pipe 133 away from the three-way pipe 132 extends to the upper side of the mounting seat 122 obliquely penetrating the top surface of the brush disc holder 1.

[0046] Referring to Figure 4The top surface of the brush disc frame 1 and the two corners on the front side of the brush disc frame 1 are fixedly connected with connecting seats 14, the water blocking frame 2 is provided with hinges 21 corresponding to the positions of the connecting seats 14, the side of the hinge 21 away from the water blocking frame 2 is installed on the connecting seat 14, and the hinge 21 is connected with the connecting seat 14, so that the water blocking frame 2 is hinged with the brush disc frame 1, and the water blocking frame 2 can be flipped relative to the brush disc frame 1 with the hinge 21 as the hinge point.

[0047] The top surface of the brush disc frame 1 and the two corners on the rear side of the brush disc frame 1 are fixedly connected with fixed seats 15, the water blocking frame 2 is provided with buckles 22 corresponding to the positions of the fixed seats 15, the locking end of the buckle 22 is connected with the fixed seat 15, so as to lock the water blocking frame 2 on the brush disc frame 1, so that the water blocking frame 2 cannot be flipped.

[0048] Referring to Figure 4 and Figure 6 , the connecting rod assembly includes a first connecting rod 23 and a second connecting rod 24; the first connecting rod 23 and the second connecting rod 24 are arranged in parallel with each other; the top end of the first connecting rod 23 and the top end of the second connecting rod 24 are hinged on the side of the water blocking frame 2 close to the brush disc frame 1, and the bottom end of the first connecting rod 23 and the bottom end of the second connecting rod 24 are hinged with the water blocking assembly. The connection between the first connecting rod 23 and the water blocking frame 2 and the water blocking assembly, and the connection between the second connecting rod 24 and the water blocking frame 2 and the water blocking assembly form a parallelogram structure, so that the first connecting rod 23 and the second connecting rod 24 can drive the water blocking assembly to swing towards or away from the water blocking frame 2.

[0049] The water blocking assembly includes a water blocking plate 5, a pressing strip 51, and a water blocking rubber strip 52 clamped between the water blocking plate 5 and the pressing strip 51; wherein the water blocking plate 5 is located on the side of the water blocking rubber strip 52 close to the brush disc frame 1. The bottom end of the first connecting rod 23 and the bottom end of the second connecting rod 24 are hinged on the side of the water blocking plate 5 away from the water blocking rubber strip 52; the front end of the pressing strip 51 is formed with a connecting portion 511 arranged in a bent manner, the connecting portion 511 is provided with a socket 512, and the front end of the water blocking plate 5 is formed with a plug-in portion 53 corresponding to the position of the socket 512. Under the plug-in action of the plug-in portion 53 and the socket 512, the front ends of the water blocking plate 5 and the pressing strip 51 are connected.

[0050] The rear end of the water blocking plate 5 and the rear end of the pressing strip 51 are both formed with a bending portion 54 bent towards the brush disc frame 1, a sub-lock 513 is installed on the bending portion 54 located on the pressing strip 51, and a female lock 541 corresponding to and matching the position of the lock is fixed on the bending portion 54 located on the water blocking plate 5. The sub-lock 513 is buckled with the female lock 541 to fix the water blocking rubber strip 52 between the water blocking plate 5 and the pressing strip 51. At the same time, the existence of the bending portion 54 makes the rear end of the water blocking rubber strip 52 also bent, so that a gap is formed between the two groups of water blocking assemblies and at the bending portion 54 of the water blocking assembly, which is conducive to the gathering and collection of sewage.

[0051] In order to be able to adjust the height of the water-stopping rubber strip 52, a plurality of equally spaced adjusting openings 521 are formed on the water-stopping rubber strip 52, and the plurality of adjusting openings 521 are located on the same vertical line; the water-stopping plate 5 is formed with a plug-in block matched with the adjusting opening 521 on the side close to the water-stopping rubber strip 52, and when the plug-in block is plugged into the adjusting opening 521 with different heights, the height of the water-stopping rubber strip 52 is adjusted. At the same time, in order to make the water-stopping rubber strip 52 be clamped more stably between the pressing strip 51 and the water-stopping plate 5, in the embodiment, a plurality of plug-in blocks are provided, and the plurality of plug-in blocks are equally spaced in the horizontal direction on the water-stopping plate 5, the number of adjusting openings 521 located in the same horizontal direction is consistent with the number of plug-in blocks and one-to-one correspondence.

[0052] The bottom surface of the water-stopping plate 5 is formed with an outward turning portion 55 arranged obliquely, the outward turning portion 55 is outward turned at a predetermined angle, and the inclined direction of the outward turning portion 55 is inclined downward away from the brush disc holder 1. The existence of the outward turning portion 55 makes the part of the water-stopping rubber strip 52 in contact with the outward turning portion 55 also outward turn at a predetermined angle, so that the water-stopping part of the water-stopping rubber strip 52 can maintain the best water wiping effect.

[0053] In the embodiment, the elastic member 3 is a tension spring, the bottom end of the second connecting rod 24 is formed with an extension portion 241, one end of the tension spring is hooked on the extension portion 241, and the side of the water-stopping plate 5 away from the water-stopping rubber strip 52 is fixedly connected with a fixed block 56, and the other end of the tension spring away from the extension portion 241 is hooked on the fixed block 56. Thus, the tension spring is used to pull the water-stopping plate 5 to move away from the water-stopping frame 2, and provide a downward pressure for the water-stopping rubber strip 52.

[0054] The side of the water-stopping plate 5 close to the brush disc holder 1 and located at the bending portion 54 of the water-stopping plate 5 is provided with a guide wheel 57, and the guide wheel 57 can rotate relative to the water-stopping plate 5. When the guide wheel 57 contacts the ground, the water-stopping rubber strip 52 no longer presses downward, which is the maximum pressing amount of the water-stopping rubber strip 52 and the best pressing angle. When the brush disc holder 1 moves backward, under the friction force of the water-stopping rubber strip 52 and the ground, the connecting rod assembly tends to swing downward, which hinders the brush disc holder 1 from moving backward. At this time, the guide wheel 57 offsets the swinging tendency of the connecting rod assembly by rolling, so as to realize smooth operation.

[0055] Referring to Figure 4 and Figure 7 , the limiting member 4 is a limiting cylinder, the limiting cylinder is arranged on the side of the water-stopping frame 2 close to the brush disc holder 1, and the circumferential side of the limiting cylinder abuts against the first connecting rod 23 to limit the first connecting rod 23, so as to limit the swinging range of the water-stopping rubber strip 52; when the first connecting rod 23 contacts the circumferential side of the limiting cylinder, the first connecting rod 23 no longer swings downward.

[0056] Referring to Figure 7 and Figure 8The water baffle 2 has an elongated opening 25 corresponding to the position of the limiting cylinder. An adjustment component connected to the limiting cylinder is installed in the elongated opening 25. The adjustment component is used to adjust the position of the limiting cylinder so as to adjust the swing range of the connecting rod assembly.

[0057] The adjusting assembly includes a screw 41 rotatably connected within the elongated opening 25, an adjusting block 42 slidably connected to the elongated opening 25 and threadedly connected to the screw 41, and an adjusting member connected to the screw 41. A connecting shaft 43, coaxial with the limiting cylinder, is fixedly connected to the end face of the limiting cylinder. The end of the connecting shaft 43 furthest from the limiting cylinder is fixedly connected to the adjusting block 42. Thus, the adjusting member drives the screw 41 to rotate, causing the adjusting block 42 to move the limiting cylinder along the length of the elongated opening 25, changing the contact position between the first connecting rod 23 and the limiting cylinder, thereby adjusting the swing range of the connecting rod assembly.

[0058] Reference Figure 7 and Figure 8 The adjusting components include a bracket 44 fixedly connected to the side of the baffle 2 away from the limiting cylinder, a worm gear 45 rotatably connected to the bracket 44, a worm wheel 46 fixedly sleeved on the periphery of the screw 41 and meshing with the worm gear 45, a cylinder 47 fixedly connected to the end of the worm gear 45 away from the worm wheel 46, and a turntable 48 fixedly connected to the end of the cylinder 47 away from the worm gear 45. By rotating the turntable 48, the worm gear 45 is driven to rotate, and the rotating worm gear 45 drives the screw 41 to rotate through the worm wheel 46.

[0059] Reference Figure 8 and Figure 9 The top surface of the bracket 44 is provided with a groove 441 and a slide 442. A vertically sliding abutment shaft 443 slides in the slide 442, and a first spring 444 is fixedly connected between the inner bottom wall of the slide 442 and the bottom end of the abutment shaft 443. An extension block 445 extending out of the groove 441 is rotatably connected in the groove 441. A toggle plate 446 is fixedly connected to the top of the extension block 445. An upwardly bent pressing part 447 is formed at the end of the toggle plate 446 near the abutment shaft 443. The top end of the abutment shaft 443 abuts against the pressing part 447. A receiving groove 448 is provided at one end of the cylinder 46 away from the pressing part 447. A stop block 4481 is slidably connected in the receiving groove 448. A second spring 4482 is fixedly connected between the stop block 4481 and the receiving groove 448. A snap-fit ​​part 4483 is formed on the bottom surface of the stop block 4481 and at one end of the stop block 4481 extending outside the receiving groove 448. A plurality of snap-fit ​​grooves 449 are provided on the circumference of the cylinder 47, which are evenly distributed along the circumference. The snap-fit ​​part 4483 snaps into the snap-fit ​​groove 449 corresponding to the position to limit the rotation of the turntable 48.

[0060] Therefore, pressing down on the pressing part 447 causes the locking part 4483 to disengage from the locking groove 449. At this time, the position of the limiting cylinder can be adjusted by rotating the turntable 48 to move the adjusting block 42 within the elongated opening 25. After adjusting the position of the limiting cylinder, the pressing part 447 can be released, the first spring 444 returns to its original position, and the top of the abutment shaft 443 pushes up the pressing part 447 so that the locking part 4483 engages with the corresponding locking groove 449, thereby limiting the rotation of the turntable 48.

[0061] Reference Figure 7 and Figure 9 The two adjacent locking slots 449 are staggered to minimize the distance between them, thus facilitating the engagement of the locking part 4483 with the corresponding locking slot 449. Furthermore, the second spring 4482 and the receiving groove 448 allow the stop block 4481 to extend and retract relative to the actuating plate 446, further aiding in the engagement of the locking part 4483 with the corresponding locking slot 449. To protect the adjusting components, a protective shell (not shown in the figure) is detachably connected to the side of the water baffle 2 away from the limiting cylinder via fastening bolts. The elongated opening 25, the turntable 48, and the bracket 44 are all located within the protective shell.

[0062] The implementation principle of the lifting water-blocking system in this application embodiment is as follows: the water-blocking component, the connecting rod component, and the water-blocking frame 2 form a parallelogram structure, which allows the connecting rod component to drive the water-blocking component to swing towards or away from the water-blocking frame 2, thereby realizing the position adjustment function of the water-blocking component; the elastic element 3 pulls the water-blocking component to move away from the water-blocking frame 2, providing stable downward pressure for the water-blocking component and ensuring the contact effect between the water-blocking component and the ground; the limiting element 4 limits the swing range of the connecting rod component, effectively reducing the structural failure caused by excessive swing of the water-blocking component; the water-blocking part of the water-blocking component is turned outward at a predetermined angle, which improves the water scraping effect, reduces the risk of the water-blocking part being caught under the floor scrubbing brush 121, and improves the overall sewage collection efficiency and cleaning effect.

[0063] This application also discloses a floor scrubber using a lifting water baffle system, including a floor scrubber body and a squeegee disposed on the bottom surface of the floor scrubber body and located on the rear side of the floor scrubber body. The squeegee is used to collect the wastewater after the front water baffle assembly is blocked, that is: the squeegee is located at the end of the water baffle 5 away from the plug part 53; the brush holder 1 is installed on the bottom surface of the floor scrubber body through a lifting mechanism.

[0064] The lifting mechanism enables the brush holder 1 to be raised and lowered. The floor scrubbing brush 121 rises and falls with the brush holder 1. The water baffle 2 is connected to the brush holder 1 via hinge 21 and latch 22. The water baffle 5 is connected to the water baffle 2 via a linkage assembly to form a parallelogram structure. The tension spring provides stable downward pressure. The guide wheel 57 limits the maximum downward pressure of the water baffle strip 52. The limiter 4 limits the swing range of the linkage assembly. The pre-made outward angle of the water baffle 5 improves the wiping effect and effectively reduces the water baffle strip 52 from getting caught under the floor scrubbing brush 121. The overall structure achieves the effect of automatically adapting to the wear of the floor scrubbing brush 121, maintaining the best wiping effect, and operating stably under various working conditions, thereby improving the wastewater collection efficiency and cleaning effect.

[0065] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
