Therefore, the various sequences in the specification and the drawings are only for the purpose of clearly describing a certain embodiment and are not meant to be a required sequence, unless otherwise specified that a certain sequence must be followed.

[0041] The serial numbers of the components in this document, such as "first", "second", etc., are only used to distinguish the objects described and do not have any order or technical meaning. The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0042] This embodiment provides a floor scrubber.

[0043] Please refer to Figure 1-13 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 scraping mechanism 600 .

[0044] Please refer to Figure 1-8The seat body 100 has a bottom facing the ground, and the bottom of the seat body 100 has a sewage inlet 130 and a water outlet 111. The fan 200 is connected to the seat body 100, and is used to generate a negative pressure environment in the seat body 100 to drive the sewage to flow into the seat body 100 from the sewage inlet 130. The cleaning liquid tank 300 is used to contain the cleaning liquid, and the sewage tank 400 is used to contain the sewage. The water pump assembly 500 is used to transport the cleaning liquid in the cleaning liquid tank 300 to the water outlet 111, and transport the sewage to the sewage tank 400. The scraping condition 600 is connected to the bottom of the seat body 100, and is used to contact the ground. At least one scraping condition 600 is provided on both opposite sides of the sewage inlet 130 along the length direction of the seat body 100, so that a flow channel 610 passing through the sewage inlet 130 is formed between the scraping conditions 600 located on the opposite sides of the sewage inlet 130. A water outlet hole 111 is provided at the end of the flow channel 610 , so that the cleaning liquid flowing out of the water outlet hole 111 can flow along the flow channel 610 to the sewage inlet 130 .

[0045] When the floor scrubber is working, the cleaning liquid in the cleaning liquid tank 300 is transported to the water outlet 111 through the water pump assembly 500. The cleaning liquid flowing out of the water outlet 111 flows along the flow channel 610 to the sewage inlet 130 under the action of the suction force of the fan 200, and contacts with the dirt on the ground to drive the dirt on the ground to flow to the sewage inlet 130. That is, the cleaning liquid becomes sewage after cleaning the ground, and flows to the sewage inlet 130 for recovery. On the one hand, the scraping element 600 scrapes the ground under the drive of the seat 100 to drive the dirt attached to the ground, so that the dirt on the ground can be more easily brought into the sewage inlet 130 by the cleaning liquid. On the other hand, a flow channel 610 with a certain diversion and sealing effect is formed between the scraping elements 600, so that the sewage formed after the cleaning liquid cleans the ground can flow into the sewage inlet 130 more easily along the flow channel 610, thereby helping to reduce the residual sewage. Moreover, the cleaning effect can be achieved by only ensuring that the cleaning liquid can fill the flow channel 610. Compared with the solution of spraying the cleaning liquid on a larger open area on the ground, the consumption of the cleaning liquid can be reduced.

[0046] Please note that, please refer to Figure 1-5 The seat body 100 has a first side 150 and a second side 160 that are arranged opposite to each other. The length direction of the seat body 100 can be understood as the direction of the line connecting the midpoint of the first side 150 of the seat body 100 and the midpoint of the second side 160 of the seat body 100. In actual application scenarios, the length direction of the seat body 100 can also be understood as the direction in which the seat body 100 moves when the user pushes the seat body 100. Specifically, the length direction of the seat body 100 can also be regarded as Figure 5 The width direction of the seat body 100 is the direction perpendicular to the length direction in the horizontal plane, that is, Figure 5 The direction indicated by the central axis L2.

[0047] Since the consumption of cleaning liquid is reduced, on the one hand, the continuous working time of the floor scrubber can be increased, that is, the floor scrubber can continue to work longer after a box of cleaning liquid is filled, which is also conducive to reducing costs. On the other hand, the volume of the cleaning liquid tank 300 can be appropriately reduced, so that it is convenient to integrate the cleaning liquid tank 300 into the base 100, and it is also convenient to configure the height of the base 100 to be lower, so that the base 100 can clean some low-height gaps, for example, for cleaning the gaps under the table and the bed.

[0048] Please refer to Figure 1-5 In one embodiment, the scraper 600 extends along the width direction of the seat body 100, so that the flow channel 610 is arranged along the width direction of the seat body 100. The flow channel 610 has water outlet holes 111 at opposite ends, and the sewage inlet 130 is located in the middle of the flow channel 610, so that the cleaning liquid flowing out of the water outlet holes 111 at both ends of the flow channel 610 can flow to the middle of the flow channel 610 and be recovered from the sewage inlet 130 into the seat body 100.

[0049] On the one hand, the scraping condition 600 is arranged along the width direction of the base 100, which is conducive to improving the cleaning efficiency of the scraping condition 600 and the cleaning liquid in the flow channel 610 on the ground. When the user pushes the base 100 to move, the movement path roughly equivalent to the width of the base 100 can be cleaned. Specifically, the scraping condition 600 can extend to the side of the base 100 in the width direction of the base 100, which is conducive to improving the cleaning effect of the floor scrubber on the corner areas on the ground and reducing the cleaning dead corners. In other words, the cleaning area of ​​the floor scrubber is "to the corners" and clean. On the other hand, since water outlets are provided at both ends of the flow channel 610, the negative pressure suction force formed by the fan 200 at the sewage inlet 130 can be utilized on both sides in the width direction of the seat body 100, thereby driving the cleaning liquid flowing out of the water outlet holes 111 at both ends of the flow channel 610 to flow to the middle of the flow channel 610. The cleaning liquid contacts the ground during the flow in the flow channel 610 to clean the ground and form sewage, which is recovered from the sewage inlet 130 to the seat body 100.

[0050] Please refer to Figure 1-5 In one embodiment, water outlet terminals 110 protruding from the bottom of the seat body 100 are provided at opposite ends of the flow channel 610, the scraper 600 and the water outlet terminal 110 are surrounded along the circumference of the flow channel 610, and the water outlet hole 111 is located at the bottom of the water outlet terminal 110 and / or toward the side of the flow channel 610.

[0051] By setting the water outlet terminal 110, the water outlet terminal 110 and the scraper 600 are surrounded along the circumference of the flow channel 610, which is beneficial to enhance the sealing of the flow channel 610. It can not only reduce the possibility of sewage overflowing the flow channel 610, but also make it easier for the negative pressure suction formed by the fan 200 at the sewage inlet 130 to drive the liquid in the flow channel 610 to flow toward the sewage inlet 130.

[0052] Please refer to Figure 1-8 In one embodiment, a garbage separation box 700 is provided in the base body 100, and a garbage inlet 120 is provided at the bottom of the base body 100, and the garbage inlet 120 and the sewage inlet 130 are separated by a scraper 600. The garbage inlet 120 and the sewage inlet 130 are both connected to the garbage separation box 700, and the fan 200 is connected to the garbage separation box 700. A filter 710 is detachably installed in the garbage separation box 700, and the filter 710 is used to separate solid garbage and sewage.

[0053] On the one hand, the garbage inlet 120 and the sewage inlet 130 are separated by the scraper 600, so that larger garbage or hair can enter the garbage separation box 700 from the garbage inlet 120, but not easily enter the sewage inlet 130, thereby avoiding the situation that the sewage inlet 130 is blocked or entangled by hair. Of course, the garbage inlet 120 can be configured to be larger than the sewage inlet 130, so as to improve the passability of garbage from the garbage inlet 120 into the garbage separation box 700. On the other hand, after the garbage enters the garbage separation box 700, the solid garbage and sewage are separated by the filter 710, so that the sewage can be further transported to the sewage tank 400 later, and the solid garbage is retained in the garbage separation box 700. Specifically, the filter 710 can be a filter screen, a filter element or other structure that allows liquid to pass through and prevents solids from passing through. The filter 710 can be a detachable connection with the garbage separation box 700 through a snap structure, a magnetic structure or other mounting structure.

[0054] Please refer to Figure 1 In one embodiment, the base body 100 further includes a take-in / take-out cover 720 , and the top of the garbage separation box 700 has a take-in / take-out opening 730 , and the take-in / take-out cover 720 is used to open and close the take-in / take-out opening 730 .

[0055] When it is necessary to clean the garbage in the garbage separation box 700, the user can open the access cover 720 to take out the garbage in the garbage separation box 700 from the access opening 730 and clean the garbage separation box 700. When the floor scrubber is working, the user can cover the access cover 720 on the access opening 730 to close the access opening 730, thereby preventing garbage or sewage from splashing out of the access opening 730. The access opening 730 is located at the top of the base 100, so that when the user operates the access cover 720 and the access opening 730, there will be no visual obstruction, which is more convenient for the user to operate.

[0056] 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 120 and the sewage inlet 130, 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.

[0057] When garbage and sewage pass through the garbage separation box 700, they first enter the first sub-cavity 740, where solid garbage is blocked by the filter element 710 in the first sub-cavity 740, and 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 solid garbage and sewage. It can be understood that the first pipeline 530 of the water pump assembly 500 can be arranged to communicate with the second sub-cavity 750, so as to prevent the solid garbage from blocking the first pipeline 530.

[0058] Please refer to Figure 1-8 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 box 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 generate a negative pressure environment in the sewage tank 400 to drive the sewage to flow from the garbage separation box 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, and the fourth pipeline 560 includes two sub-pipelines 561, and the two sub-pipelines 561 respectively connect the second pump body 520 with the water outlet holes 111 at both ends of the flow channel 610. 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 two sub-pipelines 561 in sequence to the water outlet holes 111 at both ends of the flow channel 610 for discharge.

[0059] When the floor scrubber is working, the air in the sewage tank 400 is sucked by the first pump body 510 to generate a negative pressure environment in the sewage tank 400, so that the sewage in the garbage separation box 700 flows along the first pipeline 530 to the sewage tank 400 for storage under the action of the air pressure difference. The cleaning liquid in the cleaning liquid tank 300 is driven by the second pump body 520 to flow to the two water outlets 111 through the two sub-pipelines 561 of the third pipeline 550 and the fourth pipeline 560 in sequence to be discharged to clean the floor. After cleaning the floor, the cleaning liquid becomes sewage and is sucked into the garbage separation box 700, and the cycle continues.

[0060] Please refer to Figure 1-8 In one embodiment, the water pump assembly 500 also 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.

[0061] Since sewage is stored in the sewage tank 400, the second pipeline 540 should be arranged at the upper part of the sewage tank 400 as much as possible to reduce the possibility of sewage entering the second pipeline 540. However, as the amount of sewage in the sewage tank 400 increases or the posture of the seat 100 changes, in actual application scenarios, when the first pump body 510 sucks air in the sewage tank 400, it is inevitable that sewage will flow along the second pipeline 540 to the first pump body 510, and then be discharged into the seat 100, causing pollution to the internal environment of the seat 100. After the fifth pipeline 570 is added, the first pump body 510 can drive the sewage brought out of the sewage tank 400 to flow to the garbage separation box 700 through the fifth pipeline 570, and then the sewage re-enters the sewage tank 400 along the first pipeline 530 driven by the air pressure difference, thereby realizing the circulation of sewage and preventing the sewage from polluting the internal environment of the seat 100.

[0062] Please refer to Figure 1-5 , 11 and 12, in one embodiment, the floor scrubber further includes a lifting assembly 800, the lifting assembly 800 includes a driving wheel 810, a transmission assembly 820 and a lifting member 830, the driving wheel 810 is rotatably connected to the base 100, the lifting member 830 is movably connected to the base 100, and the transmission assembly 820 drives the driving wheel 810 and the lifting member 830. The lifting member 830 is located on the side of the garbage inlet 120 away from the sewage inlet 130 in the length direction of the base 100. The lifting member 830 can switch between a lifting state and a lowering state. In the lifting state, the lifting member 830 is used to form a gap with the ground. In the lowering state, the lifting member 830 is used to contact the ground. When the base 100 moves toward one end in its length direction, the driving wheel 810 drives the lifting member 830 to switch to the lifting state through the transmission assembly 820. When the seat body 100 moves toward the other end in the length direction, the driving wheel 810 drives the lifting member 830 to switch to the descending state through the transmission assembly 820 .

[0063] When using the floor scrubber, the user pushes the base 100 toward one end in the length direction of the base 100, and the friction between the ground and the driving wheel 810 causes the driving wheel 810 to rotate. The driving wheel 810 drives the lifting member 830 to switch to the lifting state through the transmission assembly 820, so that the garbage can enter the garbage inlet 120 from the gap between the lifting member 830 and the ground, thereby achieving the purpose of cleaning the ground. Specifically, when the user pushes the base 100 "forward", that is, along the Fig.11 and Fig.12 When moving in the direction indicated by the middle arrow F1, the driving wheel 810 drives the lifting member 830 to switch to the lifting state through the transmission assembly 820. When the user pulls the seat body 100 back to the other end in the length direction of the seat body 100, the friction between the ground and the driving wheel 810 causes the driving wheel 810 to rotate in the opposite direction, and the driving wheel 810 drives the lifting member 830 to switch to the lowering state through the transmission assembly 820, so that a relatively closed area is formed between the lifting member 830 and the garbage inlet 120, thereby preventing garbage from leaking out from the gap between the lifting member 830 and the ground, which is beneficial to improving the cleaning effect of the ground. Specifically, when the user pulls the seat body 100 "backward", that is, along the Fig.11 and Fig.12 When moving in the direction indicated by the middle arrow F2, the driving wheel 810 drives the lifting member 830 to switch to the descending state through the transmission assembly 820.

[0064] The transmission assembly 820 may be a transmission rope 821, a transmission connecting rod or other suitable transmission structures.

[0065] Please refer to Figure 1-5 and 11, in one embodiment, the transmission assembly 820 includes a transmission rope 821 and a rope winding portion 822, the rope winding portion 822 is connected to the base body 100, one end of the transmission rope 821 is connected to the lifting member 830, and the other end is connected to the driving wheel 810, and the middle part of the transmission rope 821 is wound around the rope winding portion 822.

[0066] When the user pushes the seat 100 forward, the friction between the ground and the driving wheel 810 causes the driving wheel 810 to rotate, and the driving wheel 810 drives the transmission rope 821 to move relative to the rope winding portion 822, and then drives the lifting member 830 to rise through the transmission rope 821, so that the lifting member 830 switches to the lifting state. When the user pulls the seat 100 backward, the friction between the ground and the driving wheel 810 causes the driving wheel 810 to rotate in the opposite direction, and then drives the lifting member 830 to descend through the transmission rope 821, so that the lifting member 830 switches to the descending state.

[0067] Please refer to Figure 1-5 In one embodiment, the transmission assembly 820 includes a first rod 823 and a second rod 824. The middle portion of the first rod 823 is rotatably connected to the seat body 100, and one end of the first rod 823 has a slide groove 825 arranged along its axial direction. One end of the second rod 824 is connected to the driving wheel 810, and the other end has a cylindrical slider 826, and the slider 826 is movably connected to the slide groove 825. One end of the first rod 823 away from the second rod 824 is rotatably connected to the lifting member 830.

[0068] When the user pushes the seat 100 forward, the friction between the ground and the driving wheel 810 causes the driving wheel 810 to rotate, and the driving wheel 810 drives the first rod 823 to rotate, so that the slider 826 on the first rod 823 moves in the slide groove 825, thereby driving the second rod 824 to rotate, and then driving the lifting member 830 to rise through the second rod 824, so that the lifting member 830 switches to the lifting state. Conversely, when the user pulls the seat 100 backward, the lifting member 830 is driven to switch to the lowering state through the first rod 823 and the second rod 824.

[0069] Please refer to Figure 1-5 , 9 and 10, in one embodiment, the scraping condition 600 includes a connecting portion 620 and a scraping portion 630, the connecting portion 620 is connected to the bottom of the base 100, one side of the scraping portion 630 is connected to the connecting portion 620, and the other side extends away from the base 100. Each scraping condition 600 includes at least one layer of the scraping portion 630.

[0070] The connection of the scraping part 600 to the bottom of the base 100 is realized by the connection part 620, and the scraping part 630 can be in contact with the ground by providing at least one layer of scraping parts 630, so as to be used for cleaning the ground. Specifically, the number of layers of the scraping parts 630 can be one layer, two layers, three layers or other suitable layers. It is understandable that providing a plurality of layers of scraping parts 630 is conducive to improving the cleaning and sealing effects of the scraping part 600.

[0071] Please refer to Figure 1-5 13. In one embodiment, the floor scrubber further comprises a one-way roller assembly 900. The bottom of the base 100 has a roller mounting position 140. The one-way roller assembly 900 comprises a roller body 910 and a limiting structure 920. The roller body 910 is rotatably connected to the roller mounting position 140. The limiting structure 920 is connected to the roller body 910. The first direction and the second direction are two opposite rotation directions of the roller body 910. The limiting structure 920 allows the roller body 910 to rotate in the first direction to drive the garbage into the garbage inlet 120, and prevents the roller body 910 from rotating in the second direction.

[0072] 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 deliver the cleaning liquid to the area to be cleaned through the water pump assembly 500. At this time, the roller body 910 is rotated in the first direction, so that sewage and garbage enter the base body 100 under the combined action of the roller body 910 force and the suction force of the fan 200, thereby achieving the effect of cleaning the floor. On the other hand, because the limiting structure 920 can prevent the roller body 910 from rotating in the second direction, when the user pulls back the base body 100 in the opposite direction, the friction between the roller body 910 and the ground cannot drive the roller body 910 to rotate in the second direction, thereby avoiding the situation where the roller body 910 brings out garbage or sewage that has not been sucked into the base body 100 in time. And when the user pulls back the seat body 100 in the opposite direction, the roller body 910 remains in contact with the ground, so that the roller body 910 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 of the fan 200, thereby helping to improve the cleaning effect.

[0073] Specifically, please refer to Figure 1 , the first direction in this embodiment is Figure 1 The counterclockwise direction in , that is, Figure 1 The second direction is 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 cleaning agents.

[0074] Please refer to Figure 1-5 In one embodiment, the base body 100 has a first side 150 and a second side 160 that are arranged opposite to each other, the roller mounting position 140 is located at the bottom of the first side 150 of the base body 100, the bottom of the base body 100 has a garbage inlet 120, and the fan 200 is connected to the garbage inlet 120. The garbage inlet 120 is arranged adjacent to the roller body 910 and is located between the first side 150 and the second side 160 of the base body 100. When the roller body 910 rotates in the first direction, it is used to drive the garbage to move toward the garbage inlet 120.

[0075] Since the garbage inlet 120 is arranged adjacent to the roller body 910 and is located between the first side 150 and the second side 160 of the base body 100, when the roller body 910 rotates along the first direction, it can drive the garbage to move toward the garbage inlet 120, so that the garbage can more easily enter the base body 100 under the suction force of the fan 200, which is beneficial to improve the cleaning effect of the floor scrubber.

[0076] Please refer to Figure 1-5In one embodiment, the floor scrubber further includes a driving motor 930, an output end of the driving motor 930 is connected to the roller body 910, and the driving motor 930 is used to drive the roller body 910 to rotate along the first direction during operation.

[0077] When the floor scrubber is in use, the roller body 910 can be driven by the driving motor 930 to rotate in the first direction, so that the roller body 910 drives garbage into the garbage inlet 120. Of course, in other embodiments, the floor scrubber may not include the driving motor 930, but when the user pushes the floor scrubber, the friction between the roller body 910 and the ground is used to drive the roller body 910 to rotate in the first direction.

[0078] Please refer to Figure 1-5 and 13. In one embodiment, the roller body 910 is provided with a contact portion 940, and the contact portion 940 is used to contact the ground.

[0079] When the floor scrubber is working, the roller body 910 drives the contact part 940 to rotate in the first direction, and then drives the garbage into the garbage inlet 120 through the contact part 940. Due to the addition of the contact part 940, when the contact part 940 is dirty during the cleaning work, the user only needs to clean or replace the contact part 940 to ensure the cleaning effect. Specifically, the contact part 940 can be made of cloth, rubber, foam or other suitable materials.

[0080] Please refer to Figure 1-3 In one embodiment, the floor scrubber further includes a handle 1000 , the base body 100 has a first side 150 and a second side 160 that are oppositely disposed, and the handle 1000 is rotatably connected to the second side 160 of the base body 100 .

[0081] When using the floor scrubber, the user can push the base 100 to move on the ground through the handle 1000. Specifically, the user applies force from the second side 160 of the base 100 through the handle 1000 to push the base 100 to move, so that the roller 910 located on the first side 150 of the base 100 can rotate in the first direction and drive the garbage into the garbage inlet 120.

[0082] Please refer to Figure 1-6 In one embodiment, the base body 100 has a bottom facing the ground, and a cleaning liquid tank 300 and a sewage tank 400 are provided in the base body 100. The cleaning liquid tank 300 and the sewage tank 400 are stacked in a direction perpendicular to the bottom side.

[0083] On the one hand, since the cleaning liquid tank 300 for containing cleaning liquid and the sewage tank 400 for containing sewage are integrated in the base 100, compared with the solution in which the clean water tank and the sewage tank 400 are arranged on the handle 1000 in the traditional solution, it is conducive to reducing the volume and weight of the handle 1000, so that the user can operate the handle 1000 more easily and labor-savingly. On the other hand, since the cleaning liquid tank 300 and the sewage tank 400 are stacked in a direction perpendicular to the bottom of the base 100, that is, the cleaning liquid tank 300 and the sewage tank 400 are usually stacked up and down in the working scene of the floor scrubber, the center of gravity of the base 100 will not shift to one side as the volume of the liquid in the cleaning liquid tank 300 and the sewage tank 400 changes during the working process, which is conducive to improving the user's operating experience.

[0084] It should be noted that when those skilled in the art consider that the cleaning liquid tank 300 and the sewage tank 400 of the floor scrubber can be set on the seat 100 connected to the handle 1000, that is, considering that the "integrated seat" in which the cleaning liquid tank 300 and the sewage tank 400 are integrated in the seat 100 can be designed, the cleaning liquid tank 300 or the sewage tank 400 is usually arranged on one side of the seat 100 and arranged side by side at the same height due to the volume limitation of the seat 100 and the need to make room for other components on the seat 100. As the volume of the liquid in the cleaning liquid tank 300 and the sewage tank 400 changes during use, the center of gravity of the seat 100 will gradually shift to the side of the seat 100 where the sewage tank 400 is located, thereby affecting the user's operating experience when lifting the seat 100 and reducing the service life of the seat 100. The cleaning liquid can be clean water or a mixture of clean water and various detergents.

[0085] Please refer to Figure 1-6 In one embodiment, the base body 100 has a first side 150, and a garbage separation box 700 is further provided in the base body 100. The garbage separation box 700 is located in the middle of the cleaning liquid tank 300 and the sewage tank 400, and the garbage separation box 700 extends to the first side 150 of the base body 100. The base body 100 has a garbage inlet 120 and a sewage inlet 130 at the bottom, and the garbage inlet 120 and the sewage inlet 130 are both connected to the garbage separation box 700, and the garbage separation box 700 is connected to the fan 200, and the fan 200 is used to generate negative pressure in the garbage separation box 700 to drive garbage and sewage into the garbage separation box 700.

[0086] When the floor scrubber is working, the air in the garbage separation box 700 is sucked by the fan 200 to generate a negative pressure environment in the garbage separation box 700, so that the garbage and sewage are driven into the garbage separation box 700 from the garbage inlet 120 and / or the sewage inlet 130 under the action of the air pressure difference. That is, by setting up the garbage separation box 700, the function of storing garbage and temporarily storing sewage is achieved. The cleaning liquid tank 300 and the sewage tank 400 are arranged roughly in a "concave" shape, and the garbage separation box 700 is arranged in the concave part of the "concave" shape, so that the garbage separation box 700 is located in the middle of the base 100, and the garbage and sewage on both sides of the bottom of the base 100 can be more easily gathered in the middle, and the effective range of the suction force of the fan 200 is larger. In addition, since the cleaning liquid tank 300, the sewage tank 400 and the garbage separation box 700 are all located in the base body 100, when the user adds cleaning liquid to the cleaning liquid tank 300 and discharges the sewage in the sewage tank 400, the garbage in the garbage separation box 700 can be cleaned at the same time, and the inside and outside of the base body 100 can also be cleaned by the way, so that the base body 100 of the floor scrubber is kept clean and the garbage or sewage is prevented from stinking in the base body 100.

[0087] Please refer to Figure 1-6 In one embodiment, an exhaust box 1200 is further provided in the base body 100, and the exhaust box 1200 is adjacent to a side of the garbage separation box 700 away from the first side 150. The bottom of the exhaust box 1200 has an outlet 1210 connected to the outside, and the fan 200 has an air inlet end and an air outlet end. The air inlet end is located in the garbage separation box 700, and the air outlet end is located in the exhaust box 1200.

[0088] When the fan 200 is working, the air inlet end of the fan 200 sucks the air in the garbage separation box 700 to generate a negative pressure environment in the garbage separation box 700, and discharges the sucked gas into the exhaust box 1200, and the gas in the exhaust box 1200 is discharged to the outside of the seat body 100 through the air outlet 1210, thereby realizing the circulation of the gas. Specifically, the air outlet 1210 can be set at the bottom of the seat body 100, so as to avoid the exhaust gas from affecting the user.

[0089] Please refer to Figure 1-8 In one embodiment, the floor scrubber further includes a power supply assembly 1100. A mounting box 1300 is further provided in the base body 100. The mounting box 1300 is located on the second side 160 of the base body 100 and is disposed adjacent to the cleaning liquid tank 300 and the sewage tank 400. The power supply assembly 1100 and the water pump assembly 500 are both disposed in the mounting box 1300.

[0090] When the floor scrubber is working, the power supply assembly 1100 supplies power to the electric drive components in the floor scrubber. For example, the power supply assembly 1100 can be used to supply power to the fan 200, the first pump body 510 and the second pump body 520. By providing the installation box 1300 and arranging both the power supply assembly 1100 and the water pump assembly 500 in the installation box 1300, on the one hand, it is convenient for maintenance personnel to centrally inspect and maintain the power supply assembly 1100 and the water pump assembly 500, and on the other hand, the power supply assembly 1100 is closer to the water pump assembly 500 that needs power supply, which is conducive to shortening the distance of circuit layout, thereby helping to reduce the failure rate of the circuit and save costs.

[0091] Please refer to Figure 1-6 In one embodiment, the base body 100 further includes a partition member 170, a first sealing cover 180 and a second sealing cover 190. The partition member 170 is located between the cleaning liquid tank 300 and the sewage tank 400, and is used to separate the cleaning liquid tank 300 from the sewage tank 400. The cleaning liquid tank 300 is disposed adjacent to the bottom of the base body 100, and the sewage tank 400 is stacked above the cleaning liquid tank 300. The top of the base body 100 has a cleaning liquid channel 310 that passes through the sewage tank 400 and connects the cleaning liquid tank 300 with the outside world, and the first sealing cover 180 is used to open and close the cleaning liquid channel 310. The side of the base body 100 has a sewage outlet 410 that connects the sewage tank 400 with the outside world, and the second sealing cover 190 is used to open and close the sewage outlet 410.

[0092] On the one hand, when the user needs to add cleaning liquid into the base 100, the user can open the first sealing cover 180, add the cleaning liquid into the cleaning liquid tank 300 through the cleaning liquid channel 310, and then cover the first sealing cover 180. Since the first sealing cover 180 and the cleaning liquid channel 310 are arranged on the top of the base 100, the user's vision will not be blocked when adding the cleaning liquid, which is convenient for the user's operation. On the other hand, since the sewage outlet 410 and the second sealing cover 190 are arranged on the side of the base 100, when the user needs to pour out the sewage in the sewage tank 400, he only needs to open the second sealing cover 190 and tilt the base 100 to the side where the sewage outlet 410 is located, without turning the base 100 180°, which is convenient for the user to pour out the sewage and can prevent the sewage from contaminating the upper surface of the base 100.

[0093] The above specific examples are used to illustrate the present invention, which is only used to help understand the present invention and is not intended to limit the present invention. For those skilled in the art, according to the concept of the present invention, some simple deductions, modifications or substitutions can be made.
