[0002] With the development and progress of intelligent electronic equipment, 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 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.

[0003] 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 in the clean water tank is insufficient to support the floor scrubber to continue cleaning, it is necessary to manually open the water tank cover of the clean water tank, inject enough water into the clean water tank, and then close the water tank cover. This series of cumbersome actions can ensure that there is enough water in the clean water tank so that the floor scrubber can continue to perform cleaning work stably. Utility Model Content

[0028] In order to make the purpose, technical solutions and advantages of the present disclosure clearer, the present disclosure will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0029] The terms used in the embodiments of the present disclosure are only for the purpose of describing specific embodiments, and are not intended to limit the present disclosure. The singular forms "a", "said" and "the" used in the embodiments of the present disclosure and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings, and "multiple" generally includes at least two, and other quantifiers are similar.

[0030] In the description of the present disclosure, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0031] It should also be noted that the term "includes", "comprising" or any other variation thereof is intended to cover non-exclusive inclusion, so that a commodity or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such commodity or device. In the absence of more restrictions, the elements defined by the sentence "comprising a ..." do not exclude the existence of other identical elements in the commodity or device including the elements.

[0032] In order to facilitate user operation, smaller and lighter floor washers are more popular among users. Based on this, the internal components of this type of floor washers are stacked more compactly, and the water tank is also smaller, which leads to insufficient water during use.

[0033] In the related art, when the amount of water in the clean water tank is insufficient to support the floor scrubber to continue cleaning, it is necessary to manually open the water tank cover of the clean water tank, inject a sufficient amount of water into the clean water tank, and then close the water tank cover. This series of cumbersome actions ensures that there is enough water in the clean water tank so that the floor scrubber can continue to perform cleaning work stably. This water supply method is cumbersome and complicated, which seriously affects the user experience.

[0034] 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. Based on the floor scrubber, the base station and the cleaning system provided by the present disclosure, 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 continuously and stably perform cleaning work.

[0035] In view of this, optional embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

[0036] A first aspect of an embodiment of the present disclosure provides a floor scrubber 100 having a body and a brush head. Figure 1 As shown, the floor scrubber 100 includes a first clean water tank 110 and a positive displacement pump 120 .

[0037] 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 spray 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 spray nozzle 150 to wet the roller brush of the brush head, so that the brush head can clean the stains on the ground.

[0038] 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 slowly flow 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.

[0039] In some embodiments, the displacement pump 120 has a first working mode and a second working 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 working mode, the clean water in the first clean water tank 110 is supplied to the brush head.

[0040] 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 clean water slowly flows to the roller brush water nozzle 150. Furthermore, clean water is sprayed from 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.

[0041] In some embodiments, in response to the displacement pump 120 being in the second operation mode, clean water in peripheral equipment of the floor scrubber 100 is supplied to the first clean water tank 110 .

[0042] 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 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.

[0043] In some embodiments, the floor scrubber 100 also includes a first valve body 130, which is connected to the volumetric 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.

[0044] Specifically, in response to the displacement pump 120 being in the first working mode and the first valve body 130 being closed, the displacement pump 120 supplies the clean water in 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. Further, the clean water is sprayed from the roller brush water nozzle 150 to wet the roller brush of the brush head to clean the ground stains.

[0045] In some embodiments, the first valve body 130 is opened to supply the clean water in the first clean water tank 110 to peripheral equipment of the floor scrubber 100 .

[0046] 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.

[0047] 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.

[0048] In other embodiments, in response to the displacement pump 120 being in the first working 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 floor scrubber; 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 130 is supplied to the brush head. How the first clean water tank 110 supplies water to the brush head or the peripheral equipment of the floor scrubber has been described in detail in the above embodiments and will not be repeated here.

[0049] In some embodiments, the first valve body 130 is a solenoid valve or a mechanical valve, which is disposed on the brush head or the body.

[0050] 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.

[0051] 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 .

[0052] 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 at the same time.

[0053] 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.

[0054] In other embodiments, the first working mode is the reverse rotation of the peristaltic pump, and the second working mode is the forward rotation of the peristaltic pump. It should be noted that, whether the pump rotation direction corresponding to the first working mode and the second working mode of the peristaltic pump is forward rotation or reverse rotation, it does not affect the peristaltic pump supplying the clean water in the first clean water tank to the brush head or peripheral equipment for water supply. Whether the pump rotation direction corresponding to the first working mode and the second working mode of the peristaltic pump is forward rotation or reverse rotation should not be a requirement for limiting the implementation of the present disclosure. In some embodiments, the first clean water tank 110 includes a water volume detection component, which is arranged inside the first clean water tank 110 and is configured to detect the water level in the first clean water tank 110, wherein the first clean water tank 110 is provided with a water level preset value, the preset value can be 200 ml, and the water level in the first clean water tank 110 is not lower than the preset value. When the water level in the first clean water tank 110 is lower than the preset value, the first control circuit 140 will trigger a low water level warning. In response to the water level peak reaching the preset value, a low water level warning is triggered, and the displacement pump 120 is in the second working mode to supply clean water in the peripheral equipment 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 detect the water level of the first clean water tank 110. When the water level is lower than a 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 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.

[0056] When the water level in the first clean water tank 110 reaches a preset value, the scrubber 100 can be placed on a peripheral device to supply water to the first clean water tank 110 of the scrubber 100, or the water tank cover can be opened manually to fill water into the first clean water tank 110 for the 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, or 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, wherein the base station 200 includes a base station base and a base station body. Figure 2As shown, the base station 200 body is disposed on the base station base for maintaining the floor scrubber 100. In some embodiments, the base station 200 further includes a second clean water tank 210, which is disposed on the base station 200 body 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 base station 200 is provided inside and connected to the second clean water tank 210. In response to the second valve body 220 being opened, the second clean water tank 210 may supply water to the peripheral device through the second valve body 220 and the second communication port 260, wherein the peripheral device may be the floor scrubber 100.

[0061] In response to the second valve body 220 being closed, the floor scrubber 100 may take in water into 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, a low water level warning is triggered, and 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 floor scrubber 100 not reaching the preset value and not triggering the low water level warning, the second control circuit 240 controls the second valve body 220 to close, so that the floor scrubber 100 supplies water to the base station 200. Specifically, the clean water flows out of the first clean water tank 110 of the floor scrubber 100, and sequentially flows through the second communication port 260 and the second valve body 220 to 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 floor scrubber 100 can be placed on the base station 200, and the first clean water tank 110 of the floor scrubber 100 can be supplied with water through the base station 200. The water tank cover can also be opened manually to fill water into the first clean water tank 110 so that the floor scrubber 100 can continue cleaning operations. In some embodiments, the base station 200 further includes a water outlet 250, which can be provided on the base of the base station for cleaning the brush head portion of the floor 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 floor scrubber 100, flows through the second connecting port 260 and the second valve body 220 to the base station 200 in sequence, and further flows out of the machine body through the water outlet 250.

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

[0067] The heater 230 can heat the clean water flowing into the scrubber 100 inside the base station 200, and then use hot water to rinse the brush head. Compared with conventional cold water rinsing, hot water rinsing the brush head can make the roller clean more thoroughly. During the operation of the scrubber 100, keeping the roller brush clean can make the cleaning surface cleaner and avoid 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 floor scrubber 100 includes a first interface, and the base station 200 includes a second interface. When the floor scrubber 100 is connected to the base station 200, the first interface and the second interface are adapted to be connected, and the floor scrubber 100 and the base station 200 are connected by water, that is, the first communication port 160 is connected to the second communication port 260. After the floor scrubber 100 is connected to the base station 200, the base station 200 can be used to maintain the floor 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 and the displacement pump 120 to reverse. In response to the first valve body 130 opening and the displacement pump 120 reversing, the second control circuit 240 controls the second valve body 220 to open, based on which 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 reversal 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. Further, 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 floor scrubber 100 can fill up the first clean water tank 110 through the base station 200 when the floor scrubber 100 is not in operation, without the need for the user to manually remove the water tank cover to add water.

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

[0074] Specifically, the clean water flows from the first clean water tank 110 of the floor scrubber 100 through the volumetric 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 may refer to the floor scrubber 100, base station 200, and cleaning system described in any of the above embodiments, and will not be elaborated here.

[0076] Finally, it should be noted that the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other. For the system or device disclosed in the embodiment, since it corresponds to the method disclosed in the embodiment, the description is relatively simple, and the relevant parts can be referred to the method part description.
