[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to Chinese patent application No. 202323667619.1 filed on December 29, 2023, and the contents of the above-mentioned Chinese patent application disclosure are hereby incorporated by reference in their entirety as a part of this application. Technical Field

[0003] The present disclosure relates to the technical field of cleaning equipment, and in particular to a floor scrubber, a base station, and a cleaning system. Background Art

[0004] With the development and progress of intelligent electronic devices, smart cleaning equipment such as vacuum cleaners and floor scrubbers are recognized and used by more and more users. A floor scrubber is a handheld floor cleaning device, usually composed of two parts: a cleaning module and a cleaning system. The cleaning module includes a clean water tank, a sewage tank, a brush head and other structures, and has functions such as automatic sewage discharge and self-cleaning of the brush head.

[0005] In order to reduce the size and weight of the floor scrubber, the volume of the clean water tank inside the floor scrubber is reduced. When the water level in the clean water tank is insufficient to support the floor scrubber to continue cleaning, it is necessary to manually open the tank cap, inject a sufficient amount of water into the tank, and then close the tank cap. This series of tedious steps is required to ensure that there is enough water in the tank to ensure the floor scrubber can continue to clean stably. Summary of the Invention

DETAILED DESCRIPTION

[0027] To make the objectives, technical solutions, and advantages of the present disclosure more clear, the present disclosure will be further described in detail below with reference to the accompanying drawings. It is apparent that the embodiments described are only a portion of the embodiments of the present disclosure, rather than all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present disclosure without creative effort are intended to fall within the scope of protection of the present disclosure.

[0028] The terms used in the embodiments of the present disclosure are for the purpose of describing specific embodiments only and are not intended to limit the present disclosure. The singular forms "a," "the," and "the" used in the embodiments of the present disclosure and the appended claims are also intended to include the plural forms, unless the context clearly indicates otherwise. "A variety of" generally includes at least two, and other quantifiers are similar.

[0029] In the description of this disclosure, it should be noted that, unless otherwise expressly specified or limited, the terms "connected" and "connection" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; and direct connections or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0030] It should also be noted that the terms "include," "comprises," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a product or device comprising a series of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such product or device. In the absence of further limitations, an element defined by the phrase "comprises a..." does not exclude the presence of other identical elements in the product or device comprising the element.

[0031] In order to facilitate user operation, smaller and lighter floor scrubbers are more popular among users. Based on this, the internal components of this type of floor scrubber are stacked more compactly, and the water tank is also smaller, which leads to insufficient water during use.

[0032] In the related art, when the water level in the clean water tank is insufficient to support the floor scrubber to continue cleaning, it is necessary to manually open the water tank cap, inject a sufficient amount of water into the clean water tank, and then close the water tank cap. This series of cumbersome steps is required to ensure that there is sufficient water in the clean water tank for the floor scrubber to continue cleaning stably. This cumbersome and complex water supply method seriously affects the user experience.

[0033] Therefore, the present disclosure provides a floor scrubber, a base station and a cleaning system. Through the first working mode of the volumetric pump of the floor scrubber, the first clean water tank can supply water to the brush head or peripheral equipment. The peripheral equipment can be a base station. A second clean water tank is arranged inside the base station. Through the second working mode of the volumetric pump, the second clean water tank of the base station can supply water to the first clean water tank of the floor scrubber. The floor scrubber, the base station and the cleaning system provided by the present disclosure can realize that when the floor scrubber is connected to the base station, the second clean water tank of the base station supplies water to the first clean water tank of the floor scrubber to ensure that there is sufficient water in the clean water tank so that the floor scrubber can perform cleaning work continuously and stably.

[0034] In view of this, optional embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

[0035] A first aspect of an embodiment of the present disclosure provides a floor scrubber 100 having a body and a brush head. As shown in FIG. 1 , the floor scrubber 100 includes a first clean water tank 110 and a positive displacement pump 120 .

[0036] The first clean water tank 110 is disposed on the machine body and is used to supply water to the brush head or peripheral equipment of the floor scrubber 100. Specifically, the floor scrubber 100 includes a roller brush water nozzle 150, which can be disposed on the brush head. When the first clean water tank 110 supplies water to the roller brush of the brush head, clean water is sprayed from the roller brush water nozzle 150 to wet the roller brush of the brush head, allowing the brush head to clean floor stains.

[0037] The volumetric pump 120 is connected to the first clean water tank 110. When the first clean water tank 110 supplies water to the roller brush, the volumetric pump 120 allows the clean water to flow slowly to the roller brush water nozzle 150, thereby preventing the clean water from overflowing onto the ground due to excessively fast water flow speed, thereby affecting the cleaning effect of the floor scrubber 100.

[0038] In some embodiments, the displacement pump 120 has a first operating mode and a second operating mode, which is used for water inlet or outlet of the floor scrubber 100. In response to the displacement pump 120 being in the first operating mode, the clean water in the first clean water tank 110 is supplied to the brush head.

[0039] Specifically, when the volumetric pump 120 is in the first working mode, the first clean water tank 110 can supply water to the roller brush water nozzle 150 through the volumetric pump 120, so that the clean water slowly flows to the roller brush water nozzle 150. Furthermore, the clean water is sprayed out by the roller brush water nozzle 150 to soak the roller brush of the brush head, so that the roller brush can clean the stains on the ground.

[0040] In some embodiments, in response to the positive displacement pump 120 being in the second operating mode, clean water in peripheral equipment of the floor scrubber 100 is supplied to the first clean water tank 110 .

[0041] Specifically, the floor scrubber 100 has a first connecting port 160. When the displacement pump 120 is in the second working mode, the displacement pump 120 is configured to pump the clean water in the peripheral equipment into the first clean water tank 110 through the first connecting port 160 to complete the water supply of the peripheral equipment to the first clean water tank 110.

[0042] In some embodiments, the floor scrubber 100 also includes a first valve body 130, which is connected to the displacement pump 120 and has two working states: closed and open. By closing the first valve body 130, the clean water in the first clean water tank 110 can be supplied to the roller brush of the brush head.

[0043] Specifically, in response to the displacement pump 120 being in the first operating mode and the first valve body 130 being closed, the displacement pump 120 supplies clean water from the first clean water tank 110 to the brush head. The first clean water tank 110 can supply water to the roller brush water nozzle 150 through the displacement pump 120, so that the clean water flows to the roller brush water nozzle 150. Furthermore, the clean water is sprayed from the roller brush water nozzle 150 to wet the roller brush of the brush head to clean the stains on the floor.

[0044] In some embodiments, the first valve body 130 is opened to supply the clean water in the first clean water tank 110 to the peripheral equipment of the floor scrubber 100 .

[0045] Specifically, in response to the displacement pump 120 being in the first working mode and the first valve body 130 being opened, the clean water in the first clean water tank 110 is transported toward the peripheral equipment through the first valve body 130 and the first connecting port 160 under the action of the displacement pump 120, that is, the clean water in the first clean water tank 110 is supplied to the peripheral equipment of the floor scrubber 100, and the peripheral equipment can use the clean water supplied by the first clean water tank 110 to clean the roller brush of the floor scrubber.

[0046] It should be noted that the opening and closing of the first valve body 130 only represent two different working states of the first valve body 130. If the functions of the first water tank 110 corresponding to the opening and closing of the first valve body 130 are swapped, the first clean water tank 110 can still supply water to the brush head or the peripheral equipment.

[0047] In other embodiments, in response to the displacement pump 120 being in the first operating mode and the first valve body 130 being closed, the clean water in the first clean water tank 110 is supplied to the peripheral equipment of the scrubber; in response to the displacement pump 120 being in the first operating mode and the first valve body 130 being open, the clean water in the first clean water tank 130 is supplied to the brush head. The process of how the first clean water tank 110 supplies water to the brush head or the peripheral equipment of the scrubber has been described in detail in the above embodiments and will not be repeated here.

[0048] In some embodiments, the first valve body 130 is a solenoid valve or a mechanical valve, and is disposed on the brush head or the body.

[0049] When the first valve body 130 is arranged on the machine body and the first connecting port 160 is arranged on the brush head, it is necessary to add a water flow pipeline at the rotating shaft position of the brush head to ensure the water flow between the floor scrubber 100 and the peripheral equipment. Furthermore, the floor scrubber 100 can supply water to the peripheral equipment, or the peripheral equipment can supply water to the floor scrubber 100.

[0050] In some embodiments, the floor scrubber 100 further includes a first control circuit 140 , and the first control circuit 140 is used to control the opening or closing of the first valve body 130 and / or the switching of the working mode of the displacement pump 120 .

[0051] The first control circuit 140 can control the opening or closing of the first valve body 130 and the switching of the working mode of the displacement pump 120 respectively, or can control the opening or closing of the first valve body 130 and the switching of the working mode of the displacement pump 120 simultaneously.

[0052] In some embodiments, the displacement pump 120 is a peristaltic pump, the first operating mode is forward rotation of the peristaltic pump, and the second operating mode is reverse rotation of the peristaltic pump.

[0053] In other embodiments, the first operating mode is reverse rotation of the peristaltic pump, and the second operating mode is forward rotation of the peristaltic pump. It should be noted that regardless of whether the pump rotation direction corresponding to the first operating mode and the second operating mode of the peristaltic pump is forward or reverse rotation, it does not affect the peristaltic pump supplying clean water in the first clean water tank to the brush head or peripheral equipment. Whether the pump rotation direction corresponding to the first operating mode and the second operating mode of the peristaltic pump is forward or reverse rotation should not be a factor limiting the implementation of the present disclosure.

[0054] In some embodiments, the first clean water tank 110 includes a water level detection assembly disposed within the first clean water tank 110 and configured to detect the water level within the first clean water tank 110. A preset water level value, such as 200 ml, is set for the first clean water tank 110, and the water level within the first clean water tank 110 must not fall below the preset value. When the water level within the first clean water tank 110 falls below the preset value, the first control circuit 140 triggers a low water level warning. In response to the water level peak reaching the preset value, triggering the low water level warning, the positive displacement pump 120 enters a second operating mode, supplying clean water from the peripheral devices of the scrubber 100 to the first clean water tank 110.

[0055] Specifically, the water volume detection component can be a float component, which includes a float base and a float body. The float base is arranged at the bottom of the first water tank, and the float is connected to the float base and is configured to perform water level detection on the first clean water tank 110. When the water level is lower than the preset value, the first control circuit 140 will control the first valve body 130 to open, and at the same time control the peristaltic pump to reverse. The peristaltic pump is configured to pump the clean water in the peripheral device into the first clean water tank 110 through the first connecting port 160 to complete the water supply of the peripheral device to the first clean water tank 110.

[0056] When the water level in the first clean water tank 110 reaches a preset value, the floor scrubber 100 can be placed on a peripheral device to supply water to the first clean water tank 110 of the floor scrubber 100 through the peripheral device, or the water tank cover can be opened manually to add water to the first clean water tank 110 for the floor scrubber 100 to continue cleaning operations.

[0057] It should be noted that the present disclosure does not limit the peripheral equipment that supplies water to the first clean water tank 110. It can be a base station for maintaining the floor scrubber 100, a water supply device with a water tank, or any other device that can supply water to the first clean water tank 110 of the floor scrubber 100.

[0058] A second aspect of the embodiments of the present disclosure provides a base station 200, comprising a base station base and a base station body. As shown in FIG2 , the base station body 200 is disposed on the base station base and is used to maintain the floor scrubber 100. In some embodiments, the base station 200 further comprises a second fresh water tank 210, which is disposed on the base station body 200 and configured to supply water to the floor scrubber 100.

[0059] Specifically, the base station 200 also includes a second connecting port 260, which is arranged corresponding to the first connecting port 160 and can be arranged on the base station base or the base station 200 body. When the floor scrubber 100 is connected to the base station 200, the first connecting port 160 is connected to the second connecting port 260, so that the base station 200 and the floor scrubber 100 are connected by water. At this time, the second clean water tank 210 is connected to the second connecting port 260, and the second clean water tank 210 can supply water to the floor scrubber 100.

[0060] In some embodiments, the base station 200 further includes a second valve body 220, which may be a solenoid valve or a mechanical valve. The second valve body 220 is disposed within the base station 200 and is connected to the second clean water tank 210. When the second valve body 220 is opened, water from the second clean water tank 210 can flow through the second valve body 220 and the second communication port 260 to supply water to a peripheral device, such as the scrubber 100.

[0061] In response to the second valve body 220 being closed, the floor scrubber 100 may take in water from the base station 200 through the second communication port 260 .

[0062] In some embodiments, the base station 200 further includes a second control circuit 240 , and the second control circuit 240 is configured to control the opening or closing of the second valve body 220 .

[0063] In response to the water level in the first clean water tank 110 of the floor scrubber 100 reaching a preset value, triggering a low water level warning, the second control circuit 240 controls the second valve body 220 to open, and the second clean water tank 210 supplies water to the first clean water tank 110 of the floor scrubber 100. Specifically, the clean water in the second clean water tank 210 flows through the second valve body 220 to the second communication port 260, and then flows out of the base through the second communication port 260.

[0064] In response to the water level in the first clean water tank 110 of the scrubber 100 not reaching a preset value and not triggering a low water level warning, the second control circuit 240 controls the second valve body 220 to close, so that the scrubber 100 supplies water to the base station 200. Specifically, the clean water flows out of the first clean water tank 110 of the scrubber 100, sequentially flows through the second communication port 260 and the second valve body 220, and reaches the base station 200.

[0065] Specifically, when the water level in the first clean water tank 110 reaches a preset value, water needs to be supplied to the first clean water tank 110. The scrubber 100 can be placed on the base station 200, and water can be supplied to the first clean water tank 110 of the scrubber 100 through the base station 200. Alternatively, the water tank cover can be manually opened to fill the first clean water tank 110 with water for the scrubber 100 to continue cleaning. In some embodiments, the base station 200 further includes a water outlet 250, which can be provided on the base of the base station and is used to clean the brush head of the scrubber 100. In response to the closing of the second valve body 220, the clean water flows out of the first clean water tank 110 of the scrubber 100, flows through the second connecting port 260 and the second valve body 220 in sequence to the base station 200, and then flows out of the scrubber body through the water outlet 250.

[0066] In some embodiments, the base station 200 further includes a heater 230 . The heater 230 is disposed upstream of the water outlet 250 and is configured to heat the water entering the floor scrubber 100 and then flow out of the water outlet 250 .

[0067] The heater 230 can heat the water flowing into the scrubber 100 within the base station 200, thereby rinsing the brush head with hot water. Compared to conventional cold water rinsing, hot water rinsing the brush head can clean the roller more thoroughly. During the operation of the scrubber 100, keeping the roller brush clean can ensure a cleaner cleaning surface and prevent stains from clogging and affecting the cleaning effect.

[0068] A third aspect of the embodiments of the present disclosure provides a cleaning system, comprising: the floor scrubber 100 described in the first aspect of the embodiments of the present disclosure and the base station 200 described in the second aspect of the embodiments of the present disclosure.

[0069] In some embodiments, the scrubber 100 includes a first interface, and the base station 200 includes a second interface. When the scrubber 100 is connected to the base station 200, the first interface and the second interface are adapted to connect, and the scrubber 100 and the base station 200 are in water communication, that is, the first communication port 160 is in communication with the second communication port 260. After the scrubber 100 is connected to the base station 200, the base station 200 can be used to perform maintenance on the scrubber 100.

[0070] When the water level in the first clean water tank 110 of the floor scrubber 100 reaches a preset value, the first control circuit 140 controls the first valve body 130 to open, causing the displacement pump 120 to reverse. In response to the opening of the first valve body 130 and the reverse rotation of the displacement pump 120, the second control circuit 240 controls the opening of the second valve body 220. As a result, the clean water in the second clean water tank 210 is pumped into the first clean water tank 110 of the floor scrubber 100 under the action of the reverse rotation of the displacement pump 120.

[0071] Specifically, under the reverse rotation of the displacement pump 120, the clean water in the second clean water tank 210 flows out of the base station 200 through the second valve body 220 and the second flow port. Since the floor scrubber 100 and the base station 200 are connected by water, the clean water flows into the floor scrubber 100 through the first communication port 160. Furthermore, the clean water flows through the first valve body 130 and the displacement pump 120 in sequence and enters the first clean water tank 110.

[0072] The second clean water tank 210 supplies water to the first clean water tank 110 of the floor scrubber 100 , so that the first clean water tank 110 can be filled up through the base station 200 when the floor scrubber 100 is not in operation, without the need for the user to manually remove the tank cover to add water.

[0073] When the water level in the first clean water tank 110 of the floor scrubber 100 has not reached a preset value, there is no need to add water to the first clean water tank 110. The first control circuit 140 controls the first valve body 130 to open, and the positive displacement pump 120 to rotate forward. In response to the first control circuit 140 controlling the first valve body 130 to open and the positive displacement pump 120 to rotate forward, the second control circuit 240 controls the second valve body 220 to close. Based on this, the clean water in the first clean water tank 110 is pumped into the base station 200 under the action of the positive displacement pump 120 rotating forward.

[0074] Specifically, the clean water flows from the first clean water tank 110 of the floor scrubber 100 through the positive displacement pump 120 and the first valve body 130, and then flows out of the floor scrubber 100 through the first connecting port 160. Then, since the first connecting port 160 is connected to the second connecting port 260, the clean water enters the base station 200 through the second connecting valve. Furthermore, since the second valve body 220 is closed, the clean water flows through the heater 230, is heated into hot water, and then flows out from the water outlet 250 to clean the roller brush of the floor scrubber 100.

[0075] The specific structure, working principle, and beneficial effects of the floor scrubber 100, base station 200, and cleaning system provided by the embodiments of the present disclosure can refer to the floor scrubber 100, base station 200, and cleaning system described in any of the above embodiments, and will not be repeated here.
