Best Mode for Carrying Out the Invention

[0030] To make the objectives, technical solutions, and advantages of the present disclosure clearer, the present disclosure will be described in more detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present disclosure, not all embodiments. Based on the embodiments of the present disclosure, other embodiments obtained by those skilled in the art without creative efforts are all included in the protection scope of the present disclosure.

[0031] It should be noted that terms such as "including" and "comprising" or any other variations are intended to cover non-exclusive inclusion. A product or device including a series of elements includes not only those elements but also other elements that are clearly listed or elements inherent to these products or devices. It should be noted that, unless further limited, elements defined by the expression "comprising..." do not exclude the existence of other identical elements in the product or device including the said elements.

[0032] In this field, a cleaning device, such as a floor washer, usually includes a device body and a cleaning base. The cleaning device usually includes a sewage tank and a clean water tank, and a main fan for suction. The cleaning base includes a cleaning roller for mopping, and the number of cleaning rollers is one, two, or more. The cleaning liquid is sprayed onto the hairy cleaning roller and / or the surface to be cleaned through a built-in water pipe. The cleaning roller rotates at a high speed to mop and clean the floor surface. At the same time, the main fan forms a negative pressure in the device air duct of the cleaning device, sucks the sewage (which may contain solid debris) on the cleaning surface from the dirt suction port of the cleaning device, and pumps it into the sewage tank.

[0033] The cleaning liquid may be a mixture of water and detergent. In some related technologies, the user has to manually add the detergent to the clean water, and it is impossible to well control the ratio of the clean water and the detergent. If the content of the detergent in the mixed cleaning liquid is too low, the cleaning effect cannot be obtained; if the content of the detergent in the mixed cleaning liquid is too high, there will be a waste of detergent. In some other related technologies, a cleaning device is provided with a detergent tank for containing the detergent and a mixing container for mixing the clean water and the detergent. It is necessary to pump the clean water and the detergent into the mixing container for mixing. The mixing container occupies a relatively large volume, and two pumping devices are required for the clean water and the detergent respectively, which are driven by different electric motors, so the structure is complex and the cost is high.

[0034] The present disclosure provides a cleaning device, which includes a cleaning base having a cleaning roller, a clean water tank configured to contain clean water, a detergent tank configured to contain detergent, and a double-head pump. The double-head pump includes a drive motor, a first pump body attached to the first side of the drive motor and configured to pump clean water, and a second pump body configured to be attached to the second side of the drive motor. The first side and the second side are provided oppositely and configured to pump detergent. The double-head pump pumps the clean water and the detergent. The double-head pump integrates an electric motor and the first pump body and the second pump body respectively located on both sides of the electric motor, so that two-pass liquid can be pumped simultaneously, the structure is simple, and space and cost can be saved.

[0035] Hereinafter, selectable embodiments of the present disclosure will be described in detail with reference to the accompanying drawings.

[0036] FIG. 1 is a schematic structural view of a cleaning device provided by some embodiments of the present disclosure. FIG. 2 is a schematic structural view of a cleaning base provided by some embodiments of the present disclosure, and the upper cover and the detergent tank are omitted. FIG. 3 is a schematic structural view of a double-head pump provided by some embodiments of the present disclosure.

[0037] As shown in FIGS. 1 to 3, some embodiments of the present disclosure provide a cleaning device 20, such as a floor washer. The cleaning device 20 includes a cleaning base 21, a device body 22, and a handle assembly 23. The device body 22 is provided above the cleaning base 21 and is movably connected to the cleaning base 21, for example, pivotally connected. The handle assembly 23 is connected to one end of the device body 22 away from the cleaning base 21 and is used for the user to operate and grip. The user grips the handle assembly 23 and operates the cleaning base 21 to perform a cleaning operation on a surface to be cleaned, such as a floor surface.

[0038] In some embodiments, the device body 22 extends in the longitudinal direction. The handle assembly 23 is connected to the upper end of the device body 22, and the cleaning base 21 is connected to the lower end of the device body 22. The device body 22 is pivotally connected to the cleaning base 21, so that the handle assembly 23 and the device body 22 can rotate relative to the cleaning base 21, thereby changing the operation angle and enabling flexible adjustment of the cleaning posture. The cleaning base 21 is provided with a lower cleaning member, such as a cleaning roller 211. Specifically, the number of cleaning rollers 211 is, for example, one or more, such as two. The cleaning roller 211 can rotate at a high speed to mop and wash the floor surface.

[0039] The cleaning device further includes a liquid supply system. The liquid supply system includes a liquid storage device, a liquid supply pipe, a liquid supply power source, and a liquid distributor. Here, the liquid storage device is used to store the cleaning liquid. The implementation method thereof may be one, two, or more containers, a container having two or more cavities inside, or a combination of the above containers. The liquid supply power source is a device that provides power for the flow of the cleaning liquid, such as a water pump. The liquid distributor is a device that distributes the cleaning liquid to the cleaning roller brush and / or the surface to be cleaned. The liquid supply pipe is a pipe through which the cleaning liquid flows from the liquid storage device to the liquid distributor under the action of the power provided by the liquid supply power source.

[0040] In some embodiments, the liquid storage device has two or more containers or cavities, at least one of the containers or cavities is used to store clear water, and the remaining containers or cavities are used to store a cleaning effect enhancing solvent such as a detergent.

[0041] In some embodiments, the cleaning device 20, such as a floor cleaner, further includes a clear water tank 26 and a waste water tank 25, both of which are detachably attached to, for example, the device main body 22. The clear water tank 26 is used to store a cleaning liquid, which may be clear water or a mixture of clear water and a detergent. The clear water may be directly distributed to the cleaning roller 21 and / or the surface to be cleaned through a liquid distributor. After being pumped from the clear water tank, it is mixed with a detergent to form a cleaning liquid and then supplied to the cleaning roller 21 and / or the surface to be cleaned through the liquid distributor, wetting the surface of the cleaning roller 211, and the cleaning roller 211 is used to perform wet cleaning on the surface to be cleaned. The waste water tank 25 is used to store the recovered waste water. When the cleaning roller 211 performs wet cleaning, waste water is generated on the surface to be cleaned, and the waste water is recovered to the waste water tank 25 through a waste water recovery pipe.

[0042] In some embodiments, the cleaning device 20 further includes a detergent tank 213, which is provided, for example, on the cleaning base 21 and is configured to store a detergent.

[0043] The cleaning device 20 further includes a double-head pump 212 as a liquid supply power source, which is configured to pump two liquids, namely a first liquid and a second liquid. The two liquids are any two of clear water, detergent, and a mixture of clear water and detergent respectively. Specifically, the double-head pump includes a drive motor 2121 and a first pump body 2122 and a second pump body 2123 provided on both sides of the drive motor 2121. The first pump body 2122 is provided, for example, on the first side of the drive motor 2121, such as the left side shown in FIG. 3, and is used to pump the first liquid. The second pump body 2123 is provided, for example, on the second side of the drive motor 2121, such as the right side shown in FIG. 3, and is used to pump the second liquid.

[0044] In the above embodiment, the drive motor 2121, the first pump body 2122, and the second pump body 2123 are formed as an integral structure. With one drive motor, the two pump bodies are driven simultaneously. Compared with the related art in which two electric motors are employed to drive two pumping devices respectively, the method of the present disclosure has a simple structure, occupies a small space, reduces the number of drive motors, and cuts costs.

[0045] In the above embodiment, the first pump body and the second pump body are respectively located on both sides of the drive motor, and both are, for example, peristaltic pumps. In other embodiments, the first pump body and the second pump body may be located on the same side of the drive motor. The first pump body and the second pump body may employ other pumping devices, such as electromagnetic pumps, diaphragm pumps, gear pumps, screw pumps, vane pumps, liquid ring pumps, etc., and they may be the same or different.

[0046] FIG. 4 is a schematic structural diagram of a mixing pipe provided by some embodiments of the present disclosure. As shown in FIGS. 1 to 4, the liquid supply pipe in the cleaning device 20 includes a mixing pipe 214. The mixing pipe 214 may be provided, for example, on the cleaning base 21. The mixing pipe 214 includes a first inlet 2141, a second inlet 2142, and a mixed liquid outlet 2143. It is used to mix the liquids entering the first inlet 2141 and the second inlet 2142 to generate and output a mixed liquid. The corresponding mixed liquid may be the first liquid or the second liquid supplied to the first pump body 2122 or the second pump body 2123, or it may be the cleaning liquid distributed on the cleaning roller 211 and / or the surface to be cleaned by a liquid distributor. In the case of the cleaning liquid, the mixed liquid outlet 2143 is the cleaning liquid outlet.

[0047] In some embodiments, as shown in FIGS. 3 and 4, the first pump body 2122 has a first pump inlet 21221 and a first pump outlet 21222. The first pump inlet 21221 is connected to the clean water tank 26 via a clean water pipe, and the first pump outlet 21222 is connected to the mixing pipe 214 via a transfer pipe. By driving the drive motor 2121, the first pump body 2122 pumps the clean water in the clean water tank 26 into the mixing pipe 214. The first pump body 2122 is, for example, a peristaltic pump and can pump clean water uniformly. The second pump body 2123 has a second pump inlet 21231 and a second pump outlet 21232. The second pump inlet 21231 is connected to the detergent tank 213 via a detergent pipe, and the second pump outlet 21232 is connected to the mixing pipe 214 (to be described later) via a transfer pipe. By driving the drive motor 2121, the second pump body 2123 pumps the detergent in the detergent tank 213 into the mixing pipe 214. The second pump body 2123 is, for example, a peristaltic pump and can pump the detergent uniformly.

[0048] As shown in FIG. 4, the mixing pipe 214 has a first inlet 2141, a second inlet 2142, and a mixed liquid outlet 2143. The first inlet 2141 communicates with the first pump outlet 21222 of the first pump body 2122 via a transfer pipe. Under the action of the first pump body 2122, the first liquid enters the mixing pipe 214 from the first inlet 2141. The second inlet 2142 communicates with the second pump outlet 21232 of the second pump body 2123. Under the action of the second pump body 2123, the second liquid enters the mixing pipe 214 from the second inlet 2142. The first liquid and the second liquid are mixed into a cleaning liquid in the mixing pipe 214 and then output from the mixed liquid outlet 2143. The mixed liquid outlet 2143 communicates with, for example, a liquid distribution port near the cleaning roller 211 via a transfer pipe, and the cleaning liquid is distributed to the cleaning roller 211 and / or the surface to be cleaned to perform wet cleaning.

[0049] In some embodiments, as shown in FIGS. 3 and 4, the first pump body 2122 further has a first pump inlet 21221 and a first pump outlet 21222, the second pump body 2123 further has a second pump inlet 21231 and a second pump outlet 21232, the second pump inlet 21231 is connected to the detergent tank 213 via a detergent pipe, and the second pump outlet 21232 is connected to the mixing pipe 214 via a transfer pipe. The mixing pipe 214 has a first inlet 2141, a second inlet 2142, and a mixed liquid outlet 2143. The second inlet 2142 communicates with the second pump outlet 21232 via a transfer pipe, the first inlet 2141 is connected to the fresh water tank 26 via a fresh water pipe, the mixed liquid outlet 2143 communicates with the first pump inlet 21221, and the first pump outlet 21222 communicates with, for example, a liquid distribution port near the cleaning roller 211 via a transfer pipe. The second pump body 2123 pumps the detergent from the detergent tank 213 to the mixing pipe 214 to mix with fresh water, and the mixed cleaning liquid is pumped by the first pump body 2122 and distributed to the cleaning roller 211 and / or the surface to be cleaned to perform wet cleaning. By advancing the mixing process to the inlet of the pump body, in the scenario of outputting and mixing liquids from two pump bodies, the problem of fresh water entering the detergent tank due to capillary action is avoided.

[0050] In some embodiments, as shown in FIG. 4, the mixing pipe 214 includes a main pipe 2144 and a branch pipe 2145, and the pipe diameter of the branch pipe 2145 is smaller than that of the main pipe 2144. The first inlet 2141 and the mixed liquid outlet 2143 are respectively provided at two opposite ends of the main pipe 2144, and the liquid entering from the first inlet 2141 flows along the main pipe 2144 to the mixed liquid outlet 2143. In some embodiments, the main pipe 2144 is, for example, linear, polygonal, curved, etc.

[0051] The second inlet 2142 is provided at an end of the branch pipe 2145 away from the main pipe 2144, and the other end of the branch pipe 2145 is connected to the main pipe 2144. As shown in FIG. 4, the branch pipe 2145 extends along a direction inclined with respect to the extending direction of the main pipe 2144 from the side wall of the main pipe 2144. For example, the extending direction of the branch pipe 2145 forms an obtuse angle with the flowing direction of the clear water in the main pipe 2144. Under the action of the second pump body 2123, the liquid entering from the second inlet 2142 flows into the main pipe 2144 along the branch pipe 2145. The branch pipe 2145 and the main pipe 2144 are provided to be inclined with respect to each other. When the liquid flows through the branch pipe 2145 and enters the main pipe 2144, the flowing direction intersects with the flowing direction of the liquid in the main pipe 2144. Therefore, the liquid in the branch pipe and the liquid in the main pipe can be better mixed to quickly form a mixed liquid. In other embodiments, the extending direction of the branch pipe 2145 and the flowing direction of the liquid in the main pipe 2144 may be perpendicular to each other or have an acute angle therebetween.

[0052] In some embodiments, the first liquid and the second liquid are mixed at a certain ratio in the mixing pipe 214. The first pump body 2122 and the second pump body 2123 having uniform outputs are simultaneously driven using the same drive motor. The first pump body 2122 and the second pump body 2123 respectively pump the first liquid and the second liquid stably and uniformly based on their respective set flow rates, thereby ensuring that the mixing ratio of the clear water and the detergent in the mixing pipe 214 is constant. By presetting the corresponding ratio, while obtaining an excellent cleaning effect, the usage amount of the detergent can be saved. Compared with the method in which the user manually controls the mixing ratio of the detergent and the clear water, the solution of the present disclosure can improve the utilization rate of the detergent and achieve a high-quality and stable cleaning effect.

[0053] In some embodiments, the flow rate of at least one of the pumping liquids in the first pump body 2122 and the second pump body 2123 is adjustable. By adjusting the flow rate of the pumping liquid, the mixing ratio of clean water and detergent can be adjusted. For example, the first pump body 2122 and / or the second pump body 2123 may adjust the flow rate of the pumping liquid by adjusting the supply voltage, and the adjustment of the supply voltage may be an adjustment of the voltage frequency, amplitude, or a combination of both. The flow rate of the pumping liquid may have a functional relationship, such as a linear relationship, with the supply voltage.

[0054] In some embodiments, the pump body, that is, the first pump body 2122 and / or the second pump body 2123, is, for example, a purchased device, and the adjustment range of its rated supply voltage is preset, and the adjustable range of the flow rate of the pumping liquid is also preset. When the required flow rate of the liquid supply is within the adjustable range of the flow rate of the pumping liquid of the pump body, the flow rate of the pumping liquid of the body can be adjusted by adjusting the supply voltage so as to meet the required flow rate of the liquid supply.

[0055] In some embodiments, in some working modes, when the required flow rate of the liquid supply is not within the adjustable range of the flow rate of the pumping liquid of the pump body and is lower than the minimum flow rate of the pumping liquid of the pump body, an intermittent working mode of the pump body is adopted to meet the required flow rate of the liquid supply, that is, the pump body can be controlled to pump the pumping liquid intermittently. Specifically, the intermittent operation of the pump can be realized by energizing or de-energizing the pump body, so that the average flow rate within a certain period of time can meet the required flow rate of the liquid supply. For example, if the required flow rate of the liquid supply is 1 mL / s, but the minimum adjustable pumping flow rate during the operation of the pump body is 2 mL / s, after adjusting the pump to the minimum flow rate value, by adopting an intermittent pumping method of working for 1 second and then stopping for 1 second, the average flow rate value can be made 1 mL / s within a cycle of 2 s, and the required flow rate of the liquid supply can be met.

[0056] In some embodiments, as shown in FIGS. 1 to 4, the double-head pump 212 is provided on the cleaning base 21. Specifically, the detergent tank 213 is provided on the cleaning base 21, the double-head pump 212 is provided between the detergent tank 213 and the bottom surface of the cleaning base 21, and the detergent tank substantially covers the double-head pump 212.

[0057] FIG. 5 is a schematic diagram of a partial structure of a cleaning body provided by some embodiments of the present disclosure, FIG. 6 is a schematic diagram of the structure of a clean water tank provided by some embodiments of the present disclosure, and FIG. 7 is a schematic diagram of the structure of a clean water tank provided by some embodiments of the present disclosure. The clean water tank shown in FIG. 7 has a different viewing angle from the clean water tank shown in FIG. 6.

[0058] In some embodiments, as shown in FIGS. 1 to 7, the cleaning device 20 includes a device body 22 pivotally connected to the cleaning base 21, and the two are, for example, cardan pivotally connected. The device body 22 has a mounting groove 221, the clean water tank 26 is detachably mounted in the mounting groove 221, the mounting groove 221 has a mounting surface 222, and a first clean water connection portion 2221 and at least one first positioning portion 2222 are provided on the mounting surface 222. The first clean water connection portion 2221 functions as an inlet of a clean water transport pipe inside the cleaning device 20. The clean water transport pipe is a pipe for transporting clean water and forms at least a part of the liquid supply pipe.

[0059] The clean water tank 26 has a connection surface 261, and the connection surface 261 corresponds to the mounting surface 222 of the mounting groove 221. For example, when the clean water tank 26 is mounted in the mounting groove 221, the mounting surface 222 substantially adheres to the connection surface 261.

[0060] In some embodiments, as shown in FIGS. 1 to 7, a second clear water connection portion 2611 and at least one second positioning portion 2612 are provided on the connection surface 261, and the second clear water connection portion 2611 is the water outlet of the clear water tank 26. When the clear water tank 26 is attached to the attachment groove 221, the first clear water connection portion 2221 is matched and docked with the second clear water connection portion 2611, so that the clear water transport pipe in the apparatus main body 22 is connected to the water outlet of the clear water tank 26. The first positioning portion 2222 is matched and docked with the second positioning portion 2612, so that the clear water tank 26 is stably attached in the attachment groove 221, and the clear water tank 26 is prevented from swinging relative to the cleaning main body 22. Further, the process of matching and docking the first positioning portion 2222 with the second positioning portion 2612 can assist in quickly identifying the attachment position of the clear water tank 26.

[0061] In some embodiments, one of the first clear water connection portion 2221 and the second clear water connection portion 2611 is a clear water joint, and the other is a clear water connection groove. For example, as shown in FIGS. 1 to 7, the first clear water connection portion 2221 is a clear water joint, which extends away from the attachment surface 222, for example, along a direction substantially perpendicular to the attachment surface 222 away from the attachment surface 222. The second clear water connection portion 2611 is a clear water connection groove, which is provided on the connection surface 261, and it is formed by being recessed from the connection surface 261 into the clear water tank 26. The outlet of the clear water tank 26 is provided, for example, at the lower part of the groove of the clear water connection groove. The clear water joint is consistent with the shape and size of the clear water connection groove. When the clear water tank 26 is attached to the attachment groove 221, the clear water joint is inserted into the clear water connection groove, and the two are matched and docked.

[0062] In some embodiments, one of the first positioning portion 2222 and the second positioning portion 2612 is a positioning protrusion, and the other is a positioning groove. For example, as shown in FIGS. 1 to 7 , the first positioning portion 2222 is, for example, a positioning protrusion that extends away from the mounting surface 222, for example, from the mounting surface 222 along a direction substantially perpendicular to the mounting surface 222. The second positioning portion 2612 is, for example, a positioning groove that is provided on the connecting surface 261 and recessed from the connecting surface 261 into the fresh water tank 26. The positioning protrusion has a shape and size that matches the positioning groove, so that when the fresh water tank 26 is attached to the mounting groove 221, the positioning protrusion is inserted into the positioning groove, and the two are mated and docked.

[0063] In some embodiments, the number of the first positioning portion 2222 and the second positioning portion 2612 may be one or more, and the two have a one-to-one correspondence.

[0064] In some embodiments, the number of the first positioning portions 2222 is, for example, two, and the two first positioning portions 2222 are provided on both sides of the first fresh water connection portion 2221, respectively. For example, the two first positioning portions 2222 are provided symmetrically with respect to the center of the first fresh water connection portion 2221. In one specific example, the mounting surface 222 is, for example, a quadrilateral, and the two first positioning portions 2222 are located on one diagonal line of the mounting surface 222. Correspondingly, the number of the second positioning portions 2612 is also, for example, two, and the two second positioning portions 2612 are provided on both sides of the second fresh water connection portion 2611, respectively. For example, the two second positioning portions 2612 are provided symmetrically with respect to the center of the second fresh water connection portion 2611. In one specific example, the connecting surface 261 is, for example, a quadrilateral, and the two second positioning portions 2612 are located on one diagonal line of the connecting surface. By adopting such a design, the fresh water tank 26 and the mounting groove 221 can be easily positioned, and the fresh water tank 26 mounted in the mounting groove 221 can be prevented from swinging relative to the device main body 22.

[0065] In some embodiments, the first clear water connection portion 2221 is also located on the corresponding diagonal line of the mounting surface 222. Correspondingly, the second clear water connection 2611 is also located on the corresponding diagonal line of the connection surface 261.

[0066] In some embodiments, as shown in FIGS. 1 to 7, the water outlet of the clear water tank 26 is provided near the upper part 262 of the clear water tank 26. Specifically, the distance between the water outlet of the clear water tank 26 and the upper part 262 of the clear water tank is smaller than the distance between the water outlet of the clear water tank and the lower part 263 of the clear water tank. For example, the ratio of the distance between the water outlet of the clear water tank 26 and the upper part 262 of the clear water tank to the distance between the water outlet of the clear water tank and the lower part 263 of the clear water tank is less than 1 / 2. By adopting such a setting, the clear water tank 26 is less likely to leak.

[0067] In some embodiments, the clear water tank 26 further includes an air inlet check valve 264, and the air inlet check valve 264 is provided at the upper part 262 of the clear water tank 26. The air inlet check valve 264 is used to balance the air pressure between the clear water tank 26 and the outside. The air inlet check valve 264 is configured to allow gas to enter the clear water tank, but prevent liquid, such as water, from overflowing into the clear water tank. The water outlet of the clear water tank 26 is provided near the upper part 262 of the clear water tank. The water in the clear water tank 26 needs to be taken out of the clear water tank by an external force. By using it, the air pressure in the clear water tank 26 decreases. When the air pressure in the clear water tank 26 continuously decreases, it is disadvantageous for taking out the clear water in the clear water tank 26. At this time, the clear water tank is communicated with the outside to allow external gas to enter the clear water tank to stably maintain the air pressure in the clear water tank 26. Usually, this is realized by providing a through hole on the clear water tank. However, if a through hole is adopted, the clear water in the clear water tank may leak from the through hole. Based on this, by adopting the air inlet check valve 264 to balance the air pressure between the clear water tank 26 and the outside, normal pressure feeding of the clear water is realized, and at the same time, no leakage of the clear water is caused.

[0068] In some embodiments, the air inlet and water shutoff valve 264 comprises a silicone cross valve, which has a simple structure, low cost, and excellent air and water shutoff performance.

[0069] In some embodiments, the fresh water tank 26 is provided with a floating object indicator, such as a floating ball, configured to detect the amount of water in the fresh water tank. The floating ball is provided, for example, on the bottom surface of the inside of the fresh water tank, and when the amount of water in the fresh water tank falls below a predetermined value, it triggers an alarm signal from an alarm device, responsive to which the user is prompted to replenish fresh water.

[0070] In some embodiments, the fresh water tank 26 is provided with a pumping pipe, one end of which is connected to the water outlet of the fresh water tank, and the other end of which is provided at the bottom of the fresh water tank 26. This ensures that most of the water in the fresh water tank is pumped out.

[0071] In this application, fresh water and cleaning liquid are also referred to as washing liquid, and are sprayed onto the cleaning roller or the surface to be cleaned when the cleaning device performs a wet cleaning operation. In the above embodiment, the fresh water is stored in the fresh water tank as an example, and the fresh water is mixed with detergent provided from the detergent tank through a mixing pipe to form a cleaning liquid, which is then sprayed onto the cleaning roller or the surface to be cleaned so that the cleaning device performs a wet cleaning operation.

[0072] In some embodiments, the cleaning device may not include a detergent tank, and only clean water is sprayed onto the cleaning roller or surface to be cleaned as a rinse liquid, allowing the cleaning device to perform a wet cleaning operation.

[0073] In some embodiments, the fresh water tank of the cleaning device may not include a detergent tank, but may contain cleaning fluid directly, which may be sprayed as a rinse directly onto the cleaning roller or surface to be cleaned, allowing the cleaning device to perform a wet cleaning operation.
