Description

Technical Field

[0001] This invention relates to the field of surface cleaning device technology, specifically to a control method for a surface cleaning device with a base station. Background Technology

[0002] The base station is used to park surface cleaning devices. A water tank (or water source) is installed in the base station. In the prior art, when the surface cleaning device is parked on the base station, the water source can supply clean water (or the liquid required for cleaning by the surface cleaning device) to the clean water tank of the surface cleaning device. Surface cleaning devices include floor scrubbers, sweeping robots, etc.

[0003] There are various existing water supply technology solutions, but further research is needed on how to achieve water supply in a simpler and more reliable way. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the defects of the prior art and propose a control method for a surface cleaning device with a base station, so as to realize water supply in a simpler and more reliable way.

[0005] Compared to existing technologies, this invention proposes a floor brush, including a base station and a surface cleaning device. The surface cleaning device has a first docking part, and the base station has a second docking part. The first and second docking parts are detachably connected. When the surface cleaning device is placed on the base station, the first and second docking parts are connected and communicate. When the surface cleaning device is removed from the base station, the first and second docking parts are separated. The base station includes a water pump, and the surface cleaning device includes a first T-junction and a floor brush water pump. The inlet of the water pump is connected to the water source of the base station, and the outlet of the water pump is connected to the second docking part. The first end of the first T-junction is connected to the clean water tank of the surface cleaning device, the second end of the first T-junction is connected to the first docking part, the third end of the first T-junction is connected to the inlet of the floor brush water pump, and the outlet of the floor brush water pump is connected to the floor brush spray hole of the surface cleaning device. When the first and second docking parts are connected and communicate, the water source supplies water to the clean water tank in sequence through the water pump, the second docking part, the first docking part, and the first T-junction. The floor brush water pump acts as a shut-off valve to prevent the first T-junction from communicating with the floor brush spray hole.

[0006] It also includes a first electrical connection connector located on the surface cleaning device and a second electrical connection connector located on the base station. The first electrical connection connector and the second electrical connection connector are detachably electrically connected. When the surface cleaning device is placed on the base station, the first electrical connection connector and the second electrical connection connector are electrically connected to communicate and supply power to the surface cleaning device. When the surface cleaning device is removed from the base station, the first electrical connection connector and the second electrical connection connector are separated from each other.

[0007] It also includes a liquid level sensor installed on the surface cleaning device. The liquid level sensor is used to detect the liquid level in the water tank. When the surface cleaning device is placed on the base station, the surface cleaning device is electrically connected through the first electrical connection connector and the second electrical connection connector to transmit the water filling signal and / or the current liquid level signal to the control unit of the base station. The control unit controls the water pump to work to fill the water tank with water to the set value.

[0008] When the surface cleaning device is placed on the base station, it first determines whether the water tank is full. If it is not full, the control unit automatically fills the water tank with water from the base station's water source until the water tank is filled to the set value and then stops.

[0009] Compared with the prior art, the present invention has the following advantages after adopting the above structure:

[0010] This disclosure improves upon the previous method by first determining whether the water tank is full when the surface cleaning device is placed on the base station. If it is not full, the control unit automatically fills the water tank from the base station's water source until the water tank reaches the set value. During water filling, the water source sequentially supplies water to the water tank through the water pump, the second docking part, the first docking part, and the first three-way valve. The floor brush water pump acts as a shut-off valve to prevent the first three-way valve from connecting with the floor brush spray holes. That is, when the water source supplies water to the water tank, the floor brush water pump is in a shut-off state, and the fluid pumped by the water pump will not leak from the floor brush water pump, thus achieving normal water supply, i.e., water supply from the water source to the water tank. Therefore, the technical solution of this disclosure can achieve water supply more simply and reliably.

[0011] In some embodiments, a boiler is also included, the outlet of the water pump is connected to the inlet of the boiler, the outlet of the boiler is connected to the second docking section, and the boiler is used to provide heated liquid water to the second docking section.

[0012] It also includes a switch for electrically connecting the power source and the boiler. The switch is electrically connected to a control unit, which controls the switch to connect the power source and the boiler, thereby enabling the boiler to provide hot liquid. Alternatively, in the case of a boiler, it also includes a switch for electrically connecting the power source and the boiler. The switch is a power switch, which the user directly operates to connect the power source and the boiler, thereby enabling the boiler to provide hot liquid.

[0013] Users can choose to fill the water tank with either boiler-heated liquid or unheated liquid using a switch.

[0014] In some embodiments, a switching valve is also included, wherein the outlet of the water pump is connected to the inlet of the switching valve, the first outlet of the switching valve is connected to the second docking part, and the connection between the outlet of the water pump and the second docking part means that the outlet of the water pump is connected to the second docking part through the switching valve, and the second outlet of the switching valve is connected to the base station spray hole of the base station. When the surface cleaning device is placed on the base station, the base station spray hole is used to clean the floor brush of the surface cleaning device placed on the base station.

[0015] The switching valve is electrically connected to the control unit, which controls the switching valve to select whether to inject water or clean the surface cleaning device placed on the base station's floor brush.

[0016] It also includes a control interface that is electrically connected to the control unit, allowing the user to select whether to add water or perform cleaning.

[0017] When the surface cleaning device is placed on the base station, the user can select via the control interface whether to perform water injection or cleaning. When water injection is selected, the control unit controls the switching valve to connect the water pump to the second docking part and start the water pump, while closing the water pump from the base station's water spray hole. When cleaning is selected, the control unit controls the switching valve to connect the water pump to the base station's water spray hole and start the water pump, while closing the water pump from the second docking part.

[0018] In some embodiments, a boiler is also included, with the outlet of the water pump connected to the inlet of the boiler and the outlet of the boiler connected to the inlet of the switching valve, the boiler being used to supply heated liquid water to the switching valve.

[0019] It also includes a switch for electrically connecting the power source and the boiler. The switch is electrically connected to a control unit, which controls the switch to connect the power source and the boiler, thereby enabling the boiler to provide hot liquid. Alternatively, it also includes a switch for electrically connecting the power source and the boiler. The switch is a power switch, which the user directly operates to connect the power source and the boiler, thereby enabling the boiler to provide hot liquid.

[0020] The switch is located on the control interface or the base station.

[0021] When the surface cleaning device is placed on the base station, the user can choose between hot water cleaning or cold water cleaning through the control interface and switch. The user can choose to clean first and then switch to heat, or vice versa.

[0022] In some embodiments, the device further includes a second three-way valve, a cleaning fluid tank, and a supply pump. The cleaning fluid tank is connected to the inlet of the supply pump, the outlet of the supply pump is connected to the first end of the second three-way valve, the second outlet of the switching valve is connected to the second end of the second three-way valve, and the third end of the second three-way valve is connected to the base station spray nozzle. The second three-way valve is used to mix the cleaning fluid in the cleaning fluid tank and the liquid from the water source to clean the floor brush of the surface cleaning device.

[0023] When the surface cleaning device is placed on the base station, the user can select cleaning or liquid cleaning via the control interface, or simultaneously start the liquid supply pump when selecting cleaning.

[0024] In some embodiments, the control interface is located at the base station and / or at the surface cleaning device. Attached Figure Description

Detailed Implementation

[0032] The following description is intended to disclose the present invention and enable those skilled in the art to implement it. The embodiments described below are merely examples, and other obvious variations will arise for those skilled in the art. The basic principles of the invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the invention.

[0033] Those skilled in the art should understand that, in the disclosure of this invention, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limiting this invention.

[0034] like Figure 1 The diagram shown is a schematic block diagram of a surface cleaning device with a base station, including a base station 1 and a surface cleaning device 2. The surface cleaning device 2 has a first docking part 18, and the base station 1 has a second docking part 3. The first docking part 18 and the second docking part 3 are detachably connected. When the surface cleaning device 2 is placed on the base station 1, the first docking part 18 and the second docking part 3 are connected and communicate with each other. When the surface cleaning device 2 is removed from the base station 1, the first docking part 18 and the second docking part 3 are separated from each other. The base station 1 includes a water pump 4, and the surface cleaning device 2 includes a first three-way connector 5 and a floor brush water pump. The inlet of the water pump 4 is connected to the water source of the base station 1, and the outlet of the water pump 4 is connected to the first three-way connector 5. The two connecting parts 3 are connected, the first end of the first three-way 5 is connected to the clean water tank 7 of the surface cleaning device 2, the second end of the first three-way 5 is connected to the first connecting part 18, the third end of the first three-way 5 is connected to the inlet of the floor brush water pump, and the outlet of the floor brush water pump is connected to the floor brush spray hole of the surface cleaning device 2. When the first connecting part 18 and the second connecting part 3 are connected, the water source supplies water to the clean water tank 7 in sequence through the water pump 4, the second connecting part 3, the first connecting part 18, and the first three-way 5. The floor brush water pump acts as a shut-off valve to prevent the first three-way 5 from connecting to the floor brush spray hole. The floor brush water pump is, for example, a peristaltic pump, which is in a shut-off state when the power is off, thus forming the function of a shut-off valve.

[0035] It also includes a first electrical connection connector 15 located on the surface cleaning device 2 and a second electrical connection connector 15 located on the base station 1. The first electrical connection connector and the second electrical connection connector 15 are detachably electrically connected. When the surface cleaning device 2 is placed on the base station 1, the first electrical connection connector and the second electrical connection connector 15 are electrically connected to communicate and supply power to the surface cleaning device 2. When the surface cleaning device 2 is removed from the base station 1, the first electrical connection connector and the second electrical connection connector 15 are separated from each other. In this example, as... Figure 6 As shown, after the first electrical connector and the second electrical connector 15 are electrically connected, they can communicate and supply power to the surface cleaning device 2 for charging. That is, the second electrical connector 15 includes a charging base 20 and a communication base 21, while the first electrical connector is provided with corresponding electrical connection terminals.

[0036] It also includes a liquid level sensor 16 installed on the surface cleaning device 2. The liquid level sensor 16 is used to detect the liquid level of the water tank 7. When the surface cleaning device 2 is placed on the base station 1, the surface cleaning device 2 is electrically connected through the first electrical connection connector and the second electrical connection connector 15 to transmit the water filling signal and / or the current liquid level signal to the control unit of the base station 1. The control unit controls the water pump 4 to work to fill the water tank 7 with water to the set value.

[0037] When the surface cleaning device 2 is placed on the base station 1, it first determines whether the water tank 7 is full. If it is not full, the control unit automatically fills the water tank 7 with water from the water source of the base station 1 until the water tank 7 is filled to the set value and then stops. This structure is simple and reliable, and significantly simplifies the water supply operation.

[0038] The water source can be tap water or a separate water tank. In this example, base station 1 is equipped with a base station water tank 6, so as to achieve the purpose of flexibly placing base station 1.

[0039] The first mating part 18 and the second mating part 3 can adopt quick-connect couplings, such as... Figure 5 As shown, for example, the surface cleaning device 2 is a floor scrubber. When the surface cleaning device 2 is installed on the base station 1, the first docking part 18 and the second docking part 3 quickly dock together. The first docking part 18 is configured as a socket, and the second docking part 3 is configured as a plug. The socket and the plug are inserted vertically, as shown. Figure 6 As shown, when the surface cleaning device 2 is removed from the base station 1, the socket and plug separate vertically, thereby separating the first docking part 18 and the second docking part 3 from each other.

[0040] In some embodiments, such as Figures 2 to 6As shown, it also includes a switching valve 9. The outlet of the water pump 4 is connected to the inlet of the switching valve 9. The first outlet of the switching valve 9 is connected to the second docking part 3. The connection between the outlet of the water pump 4 and the second docking part 3 means that the outlet of the water pump 4 is connected to the second docking part 3 through the switching valve 9. The second outlet of the switching valve 9 is connected to the base station spray hole 14 of the base station 1. When the surface cleaning device 2 is placed on the base station 1, the base station spray hole 14 is used to clean the floor brush 8 placed on the base station 1 by the surface cleaning device 2, generally the roller brush in the floor brush 8. Figure 6 As shown, the base station water spray holes 14 are arranged in multiple configurations along the roller brush axis on the base station 1, thereby providing a larger cleaning area.

[0041] The switching valve 9 is electrically connected to the control unit, which controls the switching valve 9 to select whether to inject water or clean the surface. The cleaning device 2 is placed on the floor brush 8 on the base station 1.

[0042] It also includes a control interface 19, which is electrically connected to the control unit and allows the user to select whether to add water or perform cleaning.

[0043] When the surface cleaning device 2 is placed on the base station 1, the user can make a selection through the control interface 19 to make the control unit perform water injection or cleaning. When water injection is selected, the control unit controls the switching valve 9 to switch to connect the water pump 4 to the second docking part 3 and start the water pump 4, while closing the water pump 4 from the base station spray hole 14. When cleaning is selected, the control unit controls the switching valve 9 to switch to connect the water pump 4 to the base station spray hole 14 and start the water pump 4, while closing the water pump 4 from the second docking part 3.

[0044] In addition to the automatic water filling mentioned above, the user can select via the control interface 19 whether the control unit should perform water filling or cleaning. Furthermore, this solution solves the problem that when the liquid in the clean water tank 7 of the surface cleaning device 2 is used up after mopping, there is no need to add liquid. Instead, the user can directly use the water source for cleaning via the control interface 19. At the same time, the following solution can further mix cleaning liquid and high-temperature hot water to make the roller brush of the floor brush 8 easier to clean.

[0045] Switching valve 9, such as a solenoid valve, selects between water injection and cleaning via electronic control.

[0046] In some embodiments, such as Figures 2 to 6 As shown, it also includes a boiler 10, the outlet of the water pump 4 is connected to the inlet of the boiler 10, the outlet of the boiler 10 is connected to the inlet of the switching valve 9, and the boiler 10 is used to supply heated water source liquid to the switching valve 9.

[0047] It also includes a switch 17, which is used to electrically connect the power source and the boiler 10. The switch 17 is electrically connected to the control unit, which controls the switch 17 to connect the power source and the boiler 10, thereby enabling the boiler 10 to provide hot liquid; or, it also includes a switch 17, which is used to electrically connect the power source and the boiler 10. The switch 17 is a power switch, and the user directly operates the power switch to connect the power source and the boiler 10, thereby enabling the boiler 10 to provide hot liquid.

[0048] Switch 17 is located on control interface 19 or base station 1.

[0049] When the surface cleaning device 2 is placed on the base station 1, the user can select hot water cleaning or cold water cleaning through the control interface 19 and the switch 17. The user can select cleaning first and then select the switch 17 to heat, or select the switch 17 to heat first and then select cleaning.

[0050] In some embodiments, such as Figures 2 to 6 As shown, it also includes a second three-way valve 11, a cleaning liquid tank 12, and a liquid supply pump 13. The cleaning liquid tank 12 is connected to the inlet of the liquid supply pump 13, the outlet of the liquid supply pump 13 is connected to the first end of the second three-way valve 11, the second outlet of the switching valve 9 is connected to the second end of the second three-way valve 11, and the third end of the second three-way valve 11 is connected to the base station water spray hole 14. The second three-way valve 11 is used to mix the cleaning liquid in the cleaning liquid tank 12 and the liquid from the water source to clean the floor brush 8 of the surface cleaning device 2.

[0051] When the surface cleaning device 2 is placed on the base station 1, the user can select cleaning or liquid addition cleaning through the control interface 19, or simultaneously start the liquid supply pump 13 when selecting cleaning.

[0052] The control interface 19 is located at the base station 1 and / or at the surface cleaning device 2.

[0053] The control interface 19 can be a touch interface or a mechanical switch.

[0054] The control interface 19 can be located at the base station 1 or at the surface cleaning device 2, or the function of the control interface 19 can be divided into two parts, one part at the base station 1 and the other part at the surface cleaning device 2.

[0055] The control unit can be a control circuit built around a microcontroller, such as the 51 microcontroller.

[0056] In some embodiments, such as Figure 1As shown in Figure 2, the system also includes a boiler 10, with the outlet of the water pump 4 connected to the inlet of the boiler 10, and the outlet of the boiler 10 connected to the second docking section 3. The boiler 10 is used to supply heated liquid from a water source to the second docking section 3. A switch 17 is also included, which electrically connects the power supply to the boiler 10. This switch 17 is electrically connected to a control unit, which controls the switch 17 to connect the power supply to the boiler 10, thereby enabling the boiler 10 to supply hot liquid. Alternatively, in the case of a boiler 10, a switch 17 is also included, which electrically connects the power supply to the boiler 10. The switch 17 is a power switch, and the user directly operates the power switch to connect the power supply to the boiler 10, thereby enabling the boiler 10 to supply hot liquid. The user uses the switch 17 to turn the boiler 10 on / off, thus selecting whether to inject heated liquid or unheated liquid into the clean water tank 7.

[0057] In some embodiments, when the surface cleaning device 2 is placed on the base station 1, it first checks whether the remaining power of the surface cleaning device 2 is sufficient to complete self-cleaning. If the power is insufficient, it first charges the battery to a set value and then starts self-cleaning. When the remaining power reaches the aforementioned set value, the surface cleaning device 2 sends a signal to the control unit to indicate that cleaning can begin. The control unit controls the base station's water spray nozzles 14 to spray water, while the surface cleaning device 2 controls the roller brush of the floor brush 8 to rotate. The water spray from the base station's water spray nozzles 14 and the rotation of the roller brush work together to perform cleaning. After cleaning is completed, the clean water tank 7 is automatically filled with water, thereby ensuring that the clean water tank 7 is full when the user uses the surface cleaning device 2 to clean the floor next time. The aforementioned scheme can be in two scenarios: one is that the surface cleaning device 2 is placed on the base station 1 and cleans automatically, and the other is that the surface cleaning device 2 is placed on the base station 1 and the user presses the self-cleaning button on the control interface 19 to initiate cleaning.

[0058] In some embodiments, charging is initiated first when the remaining battery power is below 10% or 15%.

[0059] In some embodiments, the battery begins self-cleaning immediately after it is charged to a value greater than or equal to a set value, while simultaneously charging.

[0060] In some embodiments, after cleaning is completed, charging continues while the water tank 7 is automatically filled with water.

[0061] In some embodiments, when the remaining power is lower than the set value, but the user does not press the self-cleaning button on the control interface 19, the charging will proceed first and the water tank 7 will automatically fill with water.

[0062] When understanding this disclosure, the above structure may be referred to other embodiments / appendices if necessary. Figure 1 And that's understood, so I won't go into details here.

[0063] The above description is merely an illustrative embodiment of the present invention. Therefore, all equivalent changes or modifications made to the structure, features, and principles described in the scope of protection of the present invention are included within the scope of protection of the present invention.
