[0002] A floor scrubber is a device used to clean the floor. The current working principle of a floor scrubber is usually to spray clean water and detergent on the floor and clean the floor through a roller. While cleaning, the sewage on the floor is sucked into the sewage tank inside the floor scrubber, thereby completing the cleaning process.

[0003] When a user pushes a floor scrubber to clean the floor, the roller of an existing floor scrubber rotates either driven by a motor or by friction with the floor, pulling garbage and sewage into the scrubber. However, due to different user habits, some users may pull the scrubber in the opposite direction after cleaning a certain area of ​​the floor. This may cause the roller to rotate in the opposite direction due to friction with the floor, potentially pulling some garbage or sewage that was not yet sucked into the scrubber onto the floor, thus affecting the cleaning effect of the scrubber. Utility Model Content

[0016] The third pipeline connects the cleaning liquid tank with the second pump body, and the bottom of the seat body also has a water outlet. The fourth pipeline connects the second pump body with the water outlet. The second pump body is used to drive the cleaning liquid in the cleaning liquid tank to flow through the third pipeline and the fourth pipeline in sequence to the water outlet for discharge.

[0017] In one embodiment, the water pump assembly further includes a fifth pipeline, which connects the first pump body with the garbage separation box, so that the first pump body can drive the sewage brought out from the sewage tank to flow to the garbage separation box through the fifth pipeline.

[0018] In one embodiment, a scraping condition is further included, which is connected to the bottom of the base body and is used to contact the ground; and the scraping condition and the roller body are respectively located on opposite sides of the garbage inlet.

This is to avoid the core portion of the present application being overwhelmed by excessive descriptions. For those skilled in the art, it is not necessary to describe these related operations in detail. They can fully understand the related operations based on the description in the specification and the general technical knowledge in the art.

[0032] In addition, the features, operations, or characteristics described in the specification may be combined in any appropriate manner to form various embodiments. Furthermore, the steps or actions in the method description may be reordered or adjusted in a manner readily apparent to those skilled in the art. Therefore, the various sequences in the specification and drawings are provided solely for the purpose of clearly describing a particular embodiment and are not intended to be mandatory, unless otherwise specified.

[0033] The serial numbers assigned to components herein, such as "first," "second," etc., are used solely to distinguish the objects being described and do not convey any sequential or technical meaning. References to "connection" and "coupling" herein, unless otherwise specified, include both direct and indirect connections (couplings).

[0034] This embodiment provides a floor scrubber with a one-way roller assembly.

[0035] Please refer to Figure 1-7 The floor scrubber includes a base 100 , a fan 200 , a cleaning liquid tank 300 , a sewage tank 400 , a water pump assembly 500 and a one-way roller assembly 600 .

[0036] Please refer to Figure 1-5 The bottom of the base 100 is provided with a roller mounting position 150, and the fan 200 is connected to the base 100 and is used to create a negative pressure environment in the base 100 to drive the garbage and sewage to be recovered into the base 100. The cleaning liquid tank 300 is used to contain cleaning liquid, and the sewage tank 400 is used to contain sewage. The water pump assembly 500 is used to transport the cleaning liquid in the cleaning liquid tank 300 to the area to be cleaned, and to transport the sewage to the sewage tank 400. The one-way roller assembly 600 includes a roller body 610 and a limiting structure 620. The roller body 610 is rotatably connected to the roller mounting position 150, and the limiting structure 620 is connected to the roller body 610. The first direction and the second direction are two opposite rotation directions of the roller body 610. The limiting structure 620 allows the roller body 610 to rotate in the first direction to drive the garbage into the base 100, and prevents the roller body 610 from rotating in the second direction.

[0037] On the one hand, when using the floor scrubber, the user can push the base 100 forward to the floor area to be cleaned, and the water pump assembly 500 delivers cleaning fluid to the area to be cleaned. At this point, the roller 610 rotates in the first direction, allowing sewage and garbage to enter the base 100 under the combined force of the roller 610 and the suction of the fan 200, thereby cleaning the floor. On the other hand, because the restraining structure 620 prevents the roller 610 from rotating in the second direction, when the user pulls the base 100 back in the opposite direction, the friction between the roller 610 and the floor cannot drive the roller 610 to rotate in the second direction, thus preventing the roller 610 from dragging out garbage or sewage that has not yet been sucked into the base 100. And when the user pulls back the seat body 100, the roller body 610 remains in contact with the ground, so that the roller body 610 has a certain sealing effect on the garbage and sewage on its side, which is beneficial to ensure that the garbage and sewage are recovered into the seat body 100 under the suction force of the fan 200, thereby improving the cleaning effect.

[0038] Specifically, please refer to Figure 1 , the first direction in this embodiment is Figure 1 In the counterclockwise direction, that is, Figure 1 The second direction is the direction indicated by the arrow R1. Figure 1 In the clockwise direction, that is, Figure 1 The cleaning liquid can be clean water or a mixture of clean water and various detergents.

[0039] Please refer to Figure 1 and 2 In one embodiment, the restriction structure 620 is configured as a ratchet pawl structure or a one-way backstop.

[0040] When the roller 610 tends to rotate in the second direction under the action of an external force, the ratchet pawl structure or one-way backstop can prevent the roller 610 from rotating in the second direction. Specifically, limiting the rotation of a shaft or roller member to only one-way movement using a ratchet pawl structure or one-way backstop has been previously applied in other technical fields, and one-way roller members or one-way rotating shafts are also available as independent products on the market.

[0041] Please refer to Figure 1-5 In one embodiment, the base 100 has a first side 110 and a second side 120 disposed opposite each other. The roller mounting position 150 is located at the bottom of the first side 110 of the base 100. The bottom of the base 100 has a garbage inlet 130, and the fan 200 is connected to the garbage inlet 130. The garbage inlet 130 is disposed adjacent to the roller 610 and is located between the first side 110 and the second side 120 of the base 100. When the roller 610 rotates in a first direction, it drives garbage toward the garbage inlet 130.

[0042] Since the garbage inlet 130 is arranged adjacent to the roller body 610 and is located between the first side 110 and the second side 120 of the base body 100, when the roller body 610 rotates along the first direction, it can drive the garbage toward the garbage inlet 130, so that the garbage can more easily enter the base body 100 under the suction force of the fan 200, thereby helping to improve the cleaning effect of the floor scrubber.

[0043] Please refer to Figure 1-5 In one embodiment, a garbage separation box 700 is provided in the base body 100, the garbage separation box 700 is connected to the garbage inlet 130, and the fan 200 is connected to the garbage separation box 700. A filter element 710 is detachably installed in the garbage separation box 700, and the filter element 710 is used to separate solid garbage and sewage.

[0044] When garbage enters the garbage separation bin 700, the solid garbage and sewage are separated by a filter element 710, allowing the sewage to be subsequently transferred to the sewage tank 400 while the solid garbage remains in the garbage separation bin 700. Specifically, the filter element 710 can be a filter screen, a filter element, or other structure that allows liquids to pass but blocks solids. The filter element 710 can be detachably connected to the garbage separation bin 700 using a snap-fit ​​mechanism, a magnetic structure, or other mounting structure.

[0045] Please refer to Figure 1-5 In one embodiment, the base body 100 further includes a take-and-place cover 720 , and the top of the garbage separation box 700 has a take-and-place opening 730 , and the take-and-place cover 720 is used to open and close the take-and-place opening 730 .

[0046] When the trash in the trash separation box 700 needs to be cleaned, the user can open the access cover 720 to remove the trash from the access opening 730 and clean the trash separation box 700. When the floor scrubber is in operation, the user can place the access cover 720 on the access opening 730 to seal the access opening 730 and prevent trash or wastewater from spilling out of the access opening 730. The access opening 730 is located at the top of the base 100, so the user's vision is unobstructed when operating the access cover 720 and the access opening 730, making operation more convenient.

[0047] Please refer to Figure 1-5 In one embodiment, a filter element 710 is detachably provided in the garbage separation box 700. The filter element 710 is tiltedly arranged in the garbage separation box 700 to separate the garbage separation box 700 into a first sub-cavity 740 and a second sub-cavity 750. The first sub-cavity 740 is connected to the garbage inlet 130 and the sewage inlet 140, and the second sub-cavity 750 is connected to the loading and unloading port 730. The filter element 710 is used to separate solid garbage and sewage passing through the filter element 710.

[0048] When garbage and sewage enter the garbage separation box 700, they first enter the first sub-cavity 740. The solid garbage is blocked by the filter element 710 in the first sub-cavity 740, while the sewage passes through the filter element 710 under the action of the air pressure difference and flows into the second sub-cavity 750, thereby achieving separation of the solid garbage and sewage. It is understood that the first pipeline 530 of the water pump assembly 500 can be arranged to communicate with the second sub-cavity 750 to prevent the solid garbage from blocking the first pipeline 530.

[0049] Please refer to Figure 4-7 In one embodiment, the water pump assembly 500 includes a first pump body 510, a second pump body 520, a first pipeline 530, a second pipeline 540, a third pipeline 550, and a fourth pipeline 560. The first pipeline 530 connects the garbage separation tank 700 with the sewage tank 400, and the second pipeline 540 connects the sewage tank 400 with the first pump body 510. The first pump body 510 is used to create a negative pressure environment in the sewage tank 400, thereby driving sewage from the garbage separation tank 700 to the sewage tank 400 through the first pipeline 530. The third pipeline 550 connects the cleaning liquid tank 300 with the second pump body 520. The bottom of the base body 100 also has a water outlet 160. The fourth pipeline 560 connects the second pump body 520 with the water outlet 160. The second pump body 520 is used to drive the cleaning liquid in the cleaning liquid tank 300 to flow through the third pipeline 550 and the fourth pipeline 560 to the water outlet 160 for discharge.

[0050] When the floor scrubber is operating, the first pump body 510 draws air from the sewage tank 400, creating a negative pressure environment within the sewage tank 400. This pressure differential causes the sewage in the waste separation tank 700 to flow along the first pipe 530 and be stored in the sewage tank 400. The second pump body 520 drives the cleaning liquid in the cleaning liquid tank 300 through the third and fourth pipes 550, 560, and out through the water outlet 160 to clean the floor. After cleaning the floor, the cleaning liquid turns into sewage and is sucked into the waste separation tank 700, repeating the cycle.

[0051] Please refer to Figure 4-7 In one embodiment, the water pump assembly 500 further includes a fifth pipeline 570 , which connects the first pump body 510 with the garbage separation box 700 , so that the first pump body 510 can drive the sewage brought out from the sewage tank 400 to flow to the garbage separation box 700 through the fifth pipeline 570 .

[0052] Because sewage tank 400 stores sewage, second conduit 540 should be placed as close to the top of tank 400 as possible to reduce the possibility of sewage entering second conduit 540. However, as the amount of sewage in tank 400 increases or the position of base 100 changes, in actual applications, when first pump 510 pumps air from tank 400, some sewage will inevitably flow along second conduit 540 toward first pump 510, where it will be discharged into base 100, contaminating the interior of base 100. With the addition of fifth conduit 570, first pump 510 can drive sewage drawn from tank 400 through fifth conduit 570 to waste separation tank 700. The sewage then re-enters tank 400 along first conduit 530, driven by the air pressure differential. This achieves a sewage circulation system and prevents sewage from contaminating the interior of base 100.

[0053] Please refer to Figure 1-5 In one embodiment, the floor scrubber further includes a scraping element 800 connected to the bottom of the base 100 for contacting the ground. The scraping element 800 and the roller body 610 are located on opposite sides of the garbage inlet 130.

[0054] Since the scraping condition 800 and the roller body 610 are respectively located on opposite sides of the garbage inlet 130, and the scraping condition 800 and the roller body 610 are both used to contact the ground, the scraping condition 800 and the roller body 610 can play a certain sealing role on the garbage and sewage on opposite sides of the garbage inlet 130, so that the garbage and sewage between the scraping condition 800 and the roller body 610 can more easily enter the base under the suction of the fan 200, which is beneficial to improve the cleaning effect of the floor scrubber.

[0055] Please refer to Figure 1-3 In one embodiment, the floor scrubber further includes a drive motor 630 , an output end of the drive motor 630 is connected to the roller body 610 , and the drive motor 630 is used to drive the roller body 610 to rotate along a first direction during operation.

[0056] When the floor scrubber is in use, the drive motor 630 can be used to drive the roller body 610 to rotate in the first direction, thereby driving garbage into the garbage inlet 130 through the roller body 610. Of course, in other embodiments, the floor scrubber may not include the drive motor 630, but instead utilize the friction between the roller body 610 and the ground when the user pushes the floor scrubber to drive the roller body 610 to rotate in the first direction.

[0057] Please refer to Figure 1-3 In one embodiment, the roller body 610 is provided with a contact portion 640 , and the contact portion 640 is used to contact the ground.

[0058] When the floor scrubber is operating, the roller 610 drives the contact portion 640 to rotate in a first direction, thereby driving garbage into the garbage inlet 130. Due to the addition of the contact portion 640, if the contact portion 640 becomes dirty during cleaning, the user only needs to clean or replace the contact portion 640 to ensure effective cleaning. Specifically, the contact portion 640 can be made of cloth, rubber, foam, or other suitable materials.

[0059] Please refer to Figure 1-5 In one embodiment, the floor scrubber further includes a handle 900 , the base 100 has a first side 110 and a second side 120 that are oppositely disposed, and the handle 900 is rotatably connected to the second side 120 of the base 100 .

[0060] When using the floor scrubber, the user can push the base 100 on the ground using the handle 900. Specifically, the user uses the handle 900 to apply force from the second side 120 of the base 100 to push the base 100, thereby causing the roller 610 located on the first side 110 of the base 100 to rotate in a first direction and drive garbage into the garbage inlet 130.

[0061] The above examples are used to illustrate the present invention, which are only used to help understand the present invention and are not intended to limit the present invention. Those skilled in the art of the present invention can make some simple deductions, modifications or substitutions based on the concept of the present invention.
