Abstract
Description
Technical Field
[0001] This disclosure relates to the field of cleaning technology, specifically to a water tank structure, cleaning equipment, and cleaning system. Background Technology
[0002] Cleaning equipment (such as robotic vacuum cleaners and automatic sweepers) is a common type of intelligent cleaning appliance, mainly used for cleaning floors (including wood floors, tiles, carpets, etc.). These cleaning devices can automatically complete the floor cleaning task, saving users time on floor cleaning.
[0003] Cleaning equipment with mopping functions achieves this primarily by incorporating a water tank within the device. This tank stores liquid, which is then supplied to cleaning components such as the mop to clean the surface. However, as the functions of cleaning equipment continue to increase, space remains limited. Therefore, how to rationally design the water tank structure to improve the space utilization of cleaning equipment is a problem that needs to be solved. Utility Model Content
[0004] This disclosure provides a water tank structure, cleaning equipment, and cleaning system, which can solve the problem of the water tank structure occupying a large space in the cleaning equipment and thus reducing space utilization.
[0005] In a first aspect, this disclosure provides a water tank structure, which includes:
[0006] First water tank;
[0007] The second water tank is connected to the first water tank. At least one of the first and second water tanks is provided with a liquid inlet for allowing liquid to enter the first and second water tanks. At least one of the first and second water tanks is provided with a liquid outlet for discharging liquid from the first and second water tanks.
[0008] An overflow structure is provided on at least one of the first water tank and the second water tank, and the overflow structure is located outside the first water tank and the second water tank.
[0009] The water tank structure disclosed herein includes a first water tank and a second water tank that are connected to each other. Both the first and second water tanks can be used to supply liquid to cleaning equipment. By positioning the first and second water tanks at different locations on the cleaning equipment, the first and second water tanks can be rationally utilized in their layout within the dispersed local space of the cleaning equipment. Therefore, the sizes of the first and second water tanks do not need to be very large, allowing for more flexible spatial arrangement of the first and second water tanks within the cleaning equipment while meeting the liquid storage capacity requirements.
[0010] It's easy to understand that as user needs increase, the functions of cleaning equipment also increase. For example, the cleaning module needs to be able to lift and overcome obstacles. Therefore, by setting up a first water tank and a second water tank, more space can be saved on the cleaning equipment, increasing the flexibility of the layout of the first water tank, the second water tank, and other functional modules. This allows for the placement of more functional modules on the cleaning equipment, thus improving its functional diversity.
[0011] Furthermore, since the water tank structure includes a first water tank and a second water tank, users or maintenance personnel can maintain the first water tank or the second water tank separately, which improves the convenience of operation for users or maintenance personnel.
[0012] In this embodiment, the overflow structure can be used to balance the air pressure inside and outside the first and second water tanks, so that the first and second water tanks can stably supply liquid to the cleaning equipment. The overflow structure can have the function of discharging gas and discharging liquid.
[0013] Specifically, in response to the liquid exceeding the preset capacity in the first and second water tanks, the overflow structure can be used to discharge the excess liquid to the outside of the first and second water tanks, thereby reducing the possibility that the excessive liquid capacity in the first and second water tanks will lead to excessive pressure in the first and second water tanks, which may cause the seals of the first and second water tanks to fail, and thus cause leakage at the inlet or outlet.
[0014] Furthermore, during the operation of the cleaning equipment, when the equipment moves or tilts, the liquid in the first and second water tanks will slosh around. For example, liquid may accumulate on one side of the first and second water tanks, causing the liquid level in a localized area of the first and second water tanks to exceed the preset capacity. In this case, the overflow structure can discharge the excess liquid to maintain pressure balance in the first and second water tanks and reduce the risk of leakage. In addition, in response to the user overfilling the first and second water tanks, the overflow structure can also discharge the excess liquid.
[0015] In this embodiment, the overflow structure can be located outside the first and second water tanks. Therefore, the overflow structure does not easily occupy the internal space of the first and second water tanks, allowing them sufficient space to hold more liquid. This increases the volume of the first and second water tanks while maintaining their overall volume. Alternatively, while keeping their volumes constant, the volume of the first and second water tanks can be reduced to allow for the placement of more functional modules on the cleaning equipment.
[0016] According to one embodiment of this disclosure, the overflow structure includes an overflow pipe, one end of which is connected to one of a first water tank and a second water tank, and the other end of which faces a designated position.
[0017] In this embodiment, the overflow pipe is located outside the first and second water tanks. Therefore, the overflow pipe does not occupy the internal space of the first and second water tanks, thereby increasing the effective volume of the first and second water tanks, which can store more liquid and thus improve cleaning efficiency and cleaning effect.
[0018] Since the first and second water tanks are connected, one end of the overflow pipe can be installed on either the first or the second water tank. In other words, the first and second water tanks can achieve overflow function through a single overflow pipe.
[0019] In this embodiment of the present disclosure, instead of having an overflow pipe for each of the first and second water tanks, the first and second water tanks share a single overflow pipe. This reduces the possibility of multiple overflow pipes occupying space in the cleaning equipment and simplifies the water tank structure, thereby reducing processing and assembly costs.
[0020] According to one embodiment of this disclosure, the overflow structure further includes a control valve for causing unidirectional flow of liquid or gas within the overflow pipe.
[0021] In this embodiment of the disclosure, the control valve can be used to control the unidirectional flow of liquid or gas in the overflow pipe, so that the liquid or gas in the overflow pipe is less likely to flow back into the first or second housing, which helps to reduce the possibility of overflow structure failure.
[0022] Specifically, taking the overflow structure installed in the first water tank as an example, when the liquid in the first water tank exceeds the preset capacity, the control valve can make the liquid in the first water tank flow into the overflow pipe and flow out to the outside of the first water tank through the overflow pipe, so that the liquid in the first water tank does not exceed the preset capacity.
[0023] The control valve can have an automatic opening function. In response to the liquid in the first water tank exceeding the preset capacity, the control valve can cause the liquid in the first water tank to actively flow to the overflow pipe and discharge the liquid in the overflow pipe to the outside of the first water tank.
[0024] According to one embodiment of this disclosure, the first water tank is provided with an overflow hole, which is connected to an overflow pipe, and the overflow hole is located at the top of the first water tank and / or the second water tank.
[0025] In this embodiment of the present disclosure, the gas or liquid in the first water tank and the second water tank can enter the overflow pipe through the overflow hole and flow out to the outside of the first water tank and the second water tank through the overflow pipe.
[0026] Specifically, the overflow orifice allows gas to flow out of the first and second water tanks. Since liquid can flow within both tanks, this flow creates negative or positive pressure buildup. Therefore, the overflow orifice allows for pressure balance between the first and second water tanks and the external environment, ensuring a stable liquid supply to the cleaning equipment.
[0027] According to one embodiment of this disclosure, the liquid inlet is disposed on one of the first water tank and the second water tank, and the first water tank and the second water tank share the same liquid inlet.
[0028] In this embodiment of the present disclosure, liquid enters either the first water tank or the second water tank through an inlet port. Since the first and second water tanks are connected and the liquid is fluid, the first and second water tanks can share the same inlet port. Specifically, in response to liquid entering one of the first and second water tanks through the inlet port, liquid can also enter the other of the first and second water tanks.
[0029] Since each of the first and second water tanks has a liquid inlet, a liquid inlet pipe matching the liquid inlet is required. In other words, the number of liquid inlet pipes corresponds to the number of liquid inlets. Therefore, in this embodiment of the present disclosure, by setting the first and second water tanks to share a single liquid inlet, the possibility of multiple liquid inlets and multiple liquid inlet pipes occupying space in the cleaning equipment can be reduced, and the water tank structure can be simplified, reducing processing and assembly costs.
[0030] According to one embodiment of this disclosure, the liquid outlet is disposed on one of the first water tank and the second water tank, and the first water tank and the second water tank share the same liquid outlet.
[0031] In this embodiment, the liquid in the first water tank and the second water tank can be discharged through the outlet. Since the first water tank and the second water tank are connected and the liquid is fluid, the first water tank and the second water tank can share the same outlet. Specifically, taking the outlet located in the first water tank as an example, in response to the liquid in the first water tank being discharged outward through the outlet, the liquid in the second water tank can enter the first water tank and be discharged through the outlet of the first water tank.
[0032] Since each of the first and second water tanks has a liquid outlet, the number of liquid outlet pipes corresponds to the number of liquid outlets. Therefore, in this embodiment of the present disclosure, by setting the first and second water tanks to share a single liquid outlet, the possibility of multiple liquid outlets and multiple liquid outlet pipes occupying space in the cleaning equipment can be reduced, and the water tank structure can be simplified, reducing processing and assembly costs.
[0033] According to one embodiment of this disclosure, one of the first water tank and the second water tank is a main water tank, and the other of the first water tank and the second water tank is a secondary water tank, wherein the main water tank is provided with a liquid outlet.
[0034] The water tank structure also includes a conveying device, which is connected to the liquid outlet and discharges the liquid from the first and second water tanks.
[0035] In this embodiment of the present disclosure, liquid from the first and second water tanks can be discharged via a conveying device for supplying liquid to the cleaning equipment. When the first and second water tanks share the same outlet, liquid from both tanks can enter the conveying device through the outlet and be output by the conveying device.
[0036] In some examples, the conveying device can actively drain the liquid from the first and second water tanks. For example, the conveying device may include a water pump. The water pump can draw liquid from the first and second water tanks to improve the liquid supply efficiency of the first and second water tanks. Furthermore, the conveying device can also easily transport liquid from the bottom of the first and second water tanks to cleaning equipment to improve the utilization rate of the liquid in the first and second water tanks.
[0037] According to one embodiment of this disclosure, the liquid outlet is located on the side of the main water tank away from the surface to be cleaned. The water tank structure also includes a liquid guide pipe, which is located inside the main water tank. One end of the liquid guide pipe is lower than a preset position of the main water tank, and the other end of the liquid guide pipe is connected to the liquid outlet.
[0038] In this embodiment, since the liquid outlet is located on the side of the main water tank away from the surface to be cleaned, the liquid at the bottom of the main water tank can be drawn out by setting a liquid guide pipe, thereby improving the utilization rate of the liquid at the bottom of the main water tank and reducing the possibility of residual liquid at the bottom of the main water tank.
[0039] Specifically, one end of the liquid guide tube can be close to or extend into the liquid at the bottom of the main water tank. Through the suction force of the conveying device, the liquid at the bottom of the main water tank can be drawn to improve the utilization rate of the liquid in the main water tank.
[0040] It should be noted that the preset position can refer to a location inside the main water tank near the bottom wall. There is a gap between the preset position and the bottom wall of the main water tank to reduce the possibility that one end of the liquid guide tube could be connected to the bottom wall of the main water tank, causing one end of the liquid guide tube to be blocked by the bottom wall and thus failing to perform its liquid guiding function.
[0041] According to one embodiment of this disclosure, the first water tank and the second water tank are respectively provided with liquid guiding holes, and the water tank structure also includes a liquid pipeline, the two ends of which are respectively connected to the liquid guiding holes of the first water tank and the second water tank.
[0042] The horizontal height of the liquid guide hole on the main water tank is lower than that on the auxiliary water tank.
[0043] In this embodiment, the first water tank and the second water tank can be connected by a liquid pipeline. Liquid in the first water tank can flow to the second water tank through the liquid pipeline, and liquid in the second water tank can flow to the first water tank through the liquid pipeline, thereby enabling the first and second water tanks to share the same inlet and outlet.
[0044] Since the inlet and outlet ports can be located in the main water tank, when supplying liquid to the cleaning equipment, the liquid in the auxiliary water tank needs to flow out through the outlet port of the main water tank. Therefore, by setting the horizontal height of the liquid guide hole in the main water tank lower than that in the auxiliary water tank, the liquid in the auxiliary water tank can flow into the main water tank more easily. This also prevents excessive liquid residue at the bottom of the auxiliary water tank, thus improving the utilization rate of the liquid within it.
[0045] According to one embodiment of this disclosure, the first water tank and the second water tank are respectively provided with connecting holes, and the water tank structure also includes a gas pipeline, the two ends of which are connected to the connecting holes of the first water tank and the second water tank respectively.
[0046] In this embodiment, the top spaces of the first and second water tanks are permeable to each other. Therefore, during the water filling process, the possibility of trapped gas in the first and second water tanks, preventing them from being filled completely, can be effectively reduced.
[0047] The gas pipeline allows the gas in the first and second water tanks to be connected. When the gas pressure in the first and second water tanks is unstable, it can be balanced through the gas pipeline and overflow structure. This allows the gas pressure in the first and second water tanks and the external environment to tend to be balanced, thereby enabling the water tank structure to provide a stable liquid supply to the cleaning equipment.
[0048] When the liquid in the first and second water tanks does not exceed a preset capacity, the gas pipeline can be used to balance the gas pressure in the first and second water tanks. When the liquid in the first and second water tanks exceeds the preset capacity, the liquid can flow through the gas pipeline within the first and second water tanks and flow out to the outside of the first and second water tanks through the overflow structure.
[0049] According to one embodiment of this disclosure, the number of first water tanks is multiple, and / or the number of second water tanks is multiple;
[0050] The number of first water tanks is multiple, the multiple first water tanks are connected to each other, and the multiple first water tanks are connected to second water tanks;
[0051] The number of second water tanks is multiple, the multiple second water tanks are connected to each other, and the multiple second water tanks are connected to the first water tank.
[0052] In this embodiment, the number of the first water tank and the second water tank can be set according to the usage requirements of the cleaning equipment and the layout of each functional module on the cleaning equipment.
[0053] When there are multiple first water tanks, the liquid supply to the cleaning equipment can be increased, thereby improving the cleaning efficiency and effect on the surface to be cleaned. Furthermore, by setting multiple first water tanks, the overall size of each tank is relatively small. Therefore, the space dispersed on the cleaning equipment can be rationally utilized to arrange more first water tanks, thus meeting the sufficient liquid supply requirements of the cleaning equipment.
[0054] Similarly, when there are multiple second water tanks, the liquid supply to the cleaning equipment can be increased, thereby improving the cleaning efficiency and effect on the surface to be cleaned. Furthermore, by setting multiple second water tanks, and considering their relatively small overall size, more space can be utilized on the cleaning equipment to accommodate more second water tanks, thus meeting the equipment's sufficient liquid supply requirements.
[0055] According to one embodiment of this disclosure, a plurality of first water tanks and a plurality of second water tanks share a single liquid inlet; and / or,
[0056] Multiple first water tanks and multiple second water tanks share a single outlet; and / or,
[0057] Multiple first water tanks and multiple second water tanks share a single overflow outlet.
[0058] In this embodiment of the present disclosure, multiple first water tanks and second water tanks are connected to each other, so that multiple first water tanks and second water tanks can share the same liquid inlet, the same liquid outlet and the same overflow hole. This can save the space occupied by the liquid inlet, liquid outlet, overflow hole and corresponding pipelines on the cleaning equipment, and is conducive to reserving more space for more functional modules, so as to improve the functional diversity of the cleaning equipment.
[0059] Secondly, this disclosure provides a cleaning device comprising:
[0060] Chassis main body
[0061] In any of the above embodiments, the water tank structure is mounted on the chassis body.
[0062] Thirdly, the present disclosure provides a cleaning system including a base station and cleaning equipment, wherein the cleaning equipment can be placed on the base station.
[0063] The beneficial effects of the water tank structure provided in this disclosure are as follows: the first water tank and the second water tank are separate structures. Therefore, the dimensions of the first water tank and the second water tank can be set relatively small so that they can be arranged in the dispersed space of the chassis body. Thus, while meeting the liquid supply requirements, the water tank structure does not occupy a large space of the chassis body, and the space saved can be used to arrange more functional modules, which is conducive to improving the functionality of the cleaning equipment.
[0064] In addition to the technical problems solved by the embodiments of the present invention, the technical features constituting the technical solutions, and the beneficial effects brought about by the technical features of these technical solutions as described above, other technical problems that can be solved by the water tank structure, cleaning equipment, and cleaning system provided by the embodiments of the present invention, other technical features included in the technical solutions, and the beneficial effects brought about by these technical features will be further explained in detail in the specific embodiments.

[0080] The accompanying drawings have illustrated specific embodiments of this disclosure, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concepts of this disclosure to those skilled in the art through reference to particular embodiments. Detailed Implementation
[0081] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims. Clearly, the described embodiments are only a portion, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without inventive effort are within the scope of protection of this disclosure.
[0082] The cleaning equipment provided in this disclosure can be a sweeper, floor scrubber, etc. Sweepers and floor scrubbers are devices for cleaning floors. Taking a sweeper as an example, the cleaning function of a sweeper is mainly achieved through the high-speed rotation of a motor. The high-speed rotation of the motor can create a vacuum inside the machine, using a high-speed airflow to suck dust, hair, and other dirt from the floor into the machine through the suction inlet. The dirt can be accumulated in a bag filter or dust box for convenient regular cleaning by the user.
[0083] The cleaning equipment provided in this embodiment may also be equipped with a water tank, which can be used to store liquid and supply liquid to cleaning components such as a mop. The mop can be used to wipe the floor after sweeping to further improve the cleaning effect on the surface to be cleaned. The water tank is usually equipped with an overflow pipe to prevent excessive liquid in the tank. In related technologies, the overflow pipe is located inside the water tank; however, the overflow pipe occupies the internal space of the water tank, which can easily lead to a reduction in the water tank volume, thereby affecting cleaning efficiency.
[0084] Based on the aforementioned technical problems, the applicant has improved the existing water tank structure. In this embodiment, by setting up two water tanks, a first water tank and a second water tank, the two water tanks can be rationally arranged within the locally dispersed space of the cleaning equipment. On the one hand, this increases the volume of the water tanks, allowing them to store sufficient liquid to ensure cleaning efficiency and effectiveness on the surface to be cleaned. On the other hand, without increasing the water tank volume, the arrangement of the first and second water tanks within the cleaning equipment space is more flexible, improving the space utilization rate of the cleaning equipment. This allows for the arrangement of more functional modules, enhancing the functionality of the cleaning equipment. Furthermore, the overflow structure can be located outside the first and second water tanks. Therefore, the overflow structure does not easily occupy the internal space of the first and second water tanks, increasing their effective volume and allowing for the storage of more liquid, thereby improving the cleaning efficiency and effectiveness on the surface to be cleaned.
[0085] The water tank structure 100, cleaning equipment, and cleaning system provided in this disclosure are described below with reference to the accompanying drawings and specific embodiments.
[0086] See Figures 1 to 4 As shown, the water tank structure 100 of this embodiment includes a first water tank 110, a second water tank 120, and an overflow structure 130.
[0087] The second water tank 120 is connected to the first water tank 110. At least one of the first water tank 110 and the second water tank 120 is provided with a liquid inlet 100a. The liquid inlet 100a is used to allow liquid to enter the first water tank 110 and the second water tank 120. At least one of the first water tank 110 and the second water tank 120 is provided with a liquid outlet 100b. The liquid outlet 100b is used to discharge the liquid in the first water tank 110 and the second water tank 120. An overflow structure 130 is provided on at least one of the first water tank 110 and the second water tank 120. The overflow structure 130 is located outside the first water tank 110 and the second water tank 120.
[0088] In this embodiment, the water tank structure 100 includes a first water tank 110 and a second water tank 120 that are connected to each other. Both the first water tank 110 and the second water tank 120 can be used to supply liquid to the cleaning equipment. By setting the first water tank 110 and the second water tank 120 at different locations on the cleaning equipment, the first water tank 110 and the second water tank 120 can be rationally arranged using the locally dispersed space on the cleaning equipment. Therefore, the sizes of the first water tank 110 and the second water tank 120 do not need to be very large, thus allowing for a more flexible spatial arrangement of the first water tank 110 and the second water tank 120 in the cleaning equipment while meeting the liquid storage capacity requirements.
[0089] It is easy to understand that as user needs continue to increase, the functions of cleaning equipment are also constantly increasing. For example, the cleaning module needs to be able to lift and overcome obstacles. Therefore, by setting up a first water tank 110 and a second water tank 120, more space can be saved on the cleaning equipment, thereby improving the flexibility of the layout of the first water tank 110, the second water tank 120, and other functional modules. This allows for the placement of more functional modules on the cleaning equipment, which is beneficial to improving the versatility of the cleaning equipment's functions.
[0090] Furthermore, since the water tank structure 100 includes a first water tank 110 and a second water tank 120, users or maintenance personnel can maintain the first water tank 110 or the second water tank 120 separately, which helps to improve the convenience of operation for users or maintenance personnel.
[0091] In some examples, the water tank structure 100 can be mounted on the chassis body 200 of the cleaning equipment. Both the first water tank 110 and the second water tank 120 can be fixed to the chassis body 200, or the first water tank 110 and the second water tank 120 can be located on different structures of the cleaning equipment, without specific limitations in this embodiment.
[0092] The first water tank 110 and the second water tank 120 can be detachably connected to the chassis body 200 by means of snap-fit or other methods.
[0093] In some examples, the first water tank 110 and the second water tank 120 can be arranged side by side, or they can be arranged at intervals according to the layout of the cleaning equipment. No specific limitation is made in the embodiments disclosed herein.
[0094] In some examples, the number of the first water tank 110 and the second water tank 120 is not limited in this embodiment. The number of the first water tank 110 and the second water tank 120 can be set according to the layout of the cleaning equipment and the liquid storage requirements.
[0095] Furthermore, in this embodiment, the shape and size of the first water tank 110 and the second water tank 120 are not limited. The specific structure of the first water tank 110 and the second water tank 120 can be set according to the layout requirements of the cleaning equipment.
[0096] In this embodiment, the overflow structure 130 can be used to balance the air pressure inside and outside the first water tank 110 and the second water tank 120, so that the first water tank 110 and the second water tank 120 can stably supply liquid to the cleaning equipment. The overflow structure 130 can have the functions of discharging gas and discharging liquid.
[0097] Specifically, in response to the liquid in the first water tank 110 and the second water tank 120 exceeding the preset capacity, the overflow structure 130 can be used to discharge the liquid exceeding the preset capacity to the outside of the first water tank 110 and the second water tank 120, so as to reduce the possibility that the excessive liquid capacity in the first water tank 110 and the second water tank 120 will cause excessive pressure in the first water tank 110 and the second water tank 120, thereby causing the first water tank 110 and the second water tank 120 to fail to seal, and thus causing leakage at the inlet port 100a or the outlet port.
[0098] Furthermore, during the operation of the cleaning equipment, when the equipment moves or tilts, the liquid in the first water tank 110 and the second water tank 120 will slosh. For example, the liquid may accumulate on one side of the first water tank 110 and the second water tank 120, causing the liquid in a certain part of the first water tank 110 and the second water tank 120 to exceed the preset capacity. At this time, the overflow structure 130 can discharge the liquid that exceeds the preset capacity to maintain the pressure balance in the first water tank 110 and the second water tank 120 and reduce the risk of leakage. In addition, in response to the user overfilling the first water tank 110 and the second water tank 120 with water, the excess liquid can also be discharged through the overflow structure 130.
[0099] In this embodiment, the overflow structure 130 can be located outside the first water tank 110 and the second water tank 120. Therefore, the overflow structure 130 can easily avoid occupying the internal space of the first water tank 110 and the second water tank 120, allowing the first water tank 110 and the second water tank 120 to have sufficient space to hold more liquid. This allows the volume of the first water tank 110 and the second water tank 120 to be increased while keeping the overall volume of the first water tank 110 and the second water tank 120 constant. Alternatively, while keeping the volume of the first water tank 110 and the second water tank 120 constant, the volume of the first water tank 110 and the second water tank 120 can be reduced to allow for the layout of more functional modules on the cleaning equipment.
[0100] It should be noted that in this embodiment, the first water tank 110 and the second water tank 120 are connected, and at least one of the first water tank 110 and the second water tank 120 is provided with an inlet hole 100a and an outlet hole. Therefore, the inlet holes 100a of the first water tank 110 and the second water tank 120 can be independent of each other, and the outlet holes of the first water tank 110 and the second water tank 120 can also be independent of each other. Alternatively, the first water tank 110 and the second water tank 120 can share the same inlet hole 100a and the same outlet hole. In this embodiment, no specific limitation is made.
[0101] For example, the first water tank 110 and the second water tank 120 may each be provided with an inlet 100a and an outlet. Liquid enters the first water tank 110 through the inlet 100a and exits the first water tank 110 through the outlet. Liquid enters the second water tank 120 through the inlet 100a and exits the second water tank 120 through the outlet.
[0102] Alternatively, the first water tank 110 and the second water tank 120 can share the same inlet port 100a and / or the same outlet port. Specifically, taking the first water tank 110 and the second water tank 120 sharing the same inlet port 100a as an example, since the first water tank 110 and the second water tank 120 are connected, liquid can flow within both tanks. Therefore, when liquid enters one of the first water tank 110 or the second water tank 120, it can flow into the other tank through its fluidity. Similarly, the fluidity of the liquid allows the liquid in the first water tank 110 and the second water tank 120 to flow out through the same outlet port, which will not be elaborated further here.
[0103] See also some of the possible implementation methods. Figure 2 As shown, the overflow structure 130 of this embodiment includes an overflow pipe 131. One end of the overflow pipe 131 is connected to one of the first water tank 110 and the second water tank 120. The other end of the overflow pipe 131 faces a designated position.
[0104] In this embodiment of the present disclosure, the overflow pipe 131 is located outside the first water tank 110 and the second water tank 120. Therefore, the overflow pipe 131 will not occupy the internal space of the first water tank 110 and the second water tank 120, so as to increase the effective volume of the first water tank 110 and the second water tank 120, thereby storing more liquid, which can help improve cleaning efficiency and cleaning effect.
[0105] Since the first water tank 110 and the second water tank 120 are connected, one end of the overflow pipe 131 can be installed on either the first water tank 110 or the second water tank 120. In other words, the first water tank 110 and the second water tank 120 can achieve overflow function through an overflow pipe 131.
[0106] In this embodiment of the present disclosure, since the first water tank 110 and the second water tank 120 are each provided with an overflow pipe 131, by setting the first water tank 110 and the second water tank 120 to share an overflow pipe 131, the possibility of multiple overflow pipes 131 occupying the space of the cleaning equipment can be reduced, and it is also beneficial to simplify the water tank structure 100 and reduce processing and assembly costs.
[0107] In some examples, one end of the overflow pipe 131 is connected to the first water tank 110 or the second water tank 120. This can be flexibly configured according to the water circuit layout of the cleaning equipment; however, this embodiment does not impose any limitations.
[0108] It should be noted that the other end of the overflow pipe 131 faces the designated position. The designated position can be set according to the position of functional modules and other structures on the cleaning equipment, and is not limited in this embodiment.
[0109] For example, taking the overflow pipe 131 located in the first water tank 110 as an example, the designated position can be the side of the first water tank 110 facing away from the surface to be cleaned. Since the functional modules are mostly located on the side of the cleaning equipment facing the surface to be cleaned, by setting the other end of the overflow pipe 131 to face away from the surface to be cleaned, the liquid overflowing from the overflow pipe 131 is less likely to enter the functional modules. Alternatively, the designated position can also be the side of the first water tank 110 facing the surface to be cleaned. Therefore, the liquid overflowing from the overflow pipe 131 can flow onto the surface to be cleaned under its own gravity, and then the liquid on the surface to be cleaned can be cleaned by the operation of the cleaning equipment.
[0110] See also some of the possible implementation methods. Figure 2 As shown, the overflow structure 130 of this embodiment may further include a control valve 132. The control valve 132 is used to allow unidirectional flow of liquid or gas within the overflow pipe 131.
[0111] In this embodiment of the disclosure, the control valve 132 can be used to control the unidirectional flow of liquid or gas in the overflow pipe 131, so that the liquid or gas in the overflow pipe 131 is less likely to flow back into the first box or the second box, which helps to reduce the possibility of overflow structure 130 failure.
[0112] Specifically, taking the overflow structure 130 installed in the first water tank 110 as an example, when the liquid in the first water tank 110 exceeds the preset capacity, the control valve 132 can make the liquid in the first water tank 110 flow into the overflow pipe 131 and flow out to the outside of the first water tank 110 through the overflow pipe 131, so that the liquid in the first water tank 110 does not exceed the preset capacity.
[0113] In some examples, control valve 132 may have an automatic opening function. In response to the liquid in the first water tank 110 exceeding a preset capacity, control valve 132 may cause the liquid in the first water tank 110 to actively flow to the overflow pipe 131 and discharge the liquid in the overflow pipe 131 to the outside of the first water tank 110.
[0114] See in some examples Figure 3As shown, control valve 132 can be disposed in overflow pipe 131. Exemplarily, control valve 132 can be disposed in the middle region of the overflow pipe 131's extension direction. In other words, overflow pipe 131 can include a first pipe body 1311 and a second pipe body 1312. Control valve 132 can be located between the first pipe body 1311 and the second pipe body 1312. Control valve 132 can connect the first pipe body 1311 and the second pipe body 1312. One end of the first pipe body 1311 can be connected to the first water tank 110, and the other end of the first pipe body 1311 can be connected to control valve 132. One end of the second pipe body 1312 is connected to control valve 132, and the other end of the second pipe body 1312 can be a free end. For example, at least a portion of the second pipe body 1312 can pass through the chassis body 200 so that the other end of the second pipe body 1312 can face the surface to be cleaned.
[0115] See also some of the possible implementation methods. Figure 1 and Figure 2 As shown, the first water tank 110 of this embodiment is provided with an overflow hole 100c. The overflow hole 100c is connected to the overflow pipe 131. The overflow hole 100c is located at the top of the first water tank 110 and / or the second water tank 120.
[0116] In this embodiment of the present disclosure, the gas or liquid in the first water tank 110 and the second water tank 120 can enter the overflow pipe 131 through the overflow hole 100c and flow out to the outside of the first water tank 110 and the second water tank 120 through the overflow pipe 131.
[0117] Specifically, the overflow orifice 100c allows gas to flow out of the first water tank 110 and the second water tank 120. Since liquid can flow within the first water tank 110 and the second water tank 120, the liquid flow creates negative or positive pressure accumulation within them. Therefore, the overflow orifice 100c allows the pressure of the first water tank 110 and the second water tank 120 to be balanced with the external environment, thus enabling the first water tank 110 and the second water tank 120 to stably supply liquid to the cleaning equipment.
[0118] In some examples, the overflow hole 100c can be located on the side wall of the first water tank 110 or the second water tank 120 away from the surface to be cleaned. In other words, the overflow hole 100c can be located at the top of the first water tank 110 or the second water tank 120. Since the gas density is low, the gas will naturally rise to the top of the first water tank 110 or the second water tank 120. Therefore, by setting the overflow hole 100c at the top of the first water tank 110 or the second water tank 120, the gas in the first water tank 110 or the second water tank 120 can be directly discharged through the overflow hole 100c during its natural upward flow.
[0119] It should be noted that, in response to the first water tank 110 and the second water tank 120 sharing the same overflow pipe 131, the first water tank 110 and the second water tank 120 can share the same overflow port.
[0120] See also some of the possible implementation methods. Figure 1 and Figure 2 As shown, in this embodiment of the present disclosure, the liquid inlet 100a is disposed on one of the first water tank 110 and the second water tank 120. The first water tank 110 and the second water tank 120 can share the same liquid inlet 100a.
[0121] In this embodiment, liquid enters either the first water tank 110 or the second water tank 120 through the inlet port 100a. Since the first water tank 110 and the second water tank 120 are connected, and the liquid is fluid, the first water tank 110 and the second water tank 120 can share the same inlet port 100a. Specifically, in response to liquid entering one of the first water tank 110 and the second water tank 120 through the inlet port 100a, liquid can also enter the other of the first water tank 110 and the second water tank 120.
[0122] Since each of the first water tank 110 and the second water tank 120 has a liquid inlet 100a, a liquid inlet pipe matching the liquid inlet 100a is required. In other words, the number of liquid inlet pipes corresponds to the number of liquid inlet 100a. Therefore, in this embodiment of the present disclosure, by setting the first water tank 110 and the second water tank 120 to share a single liquid inlet 100a, the possibility of multiple liquid inlet 100a and multiple liquid inlet pipes occupying space in the cleaning equipment can be reduced, and it is beneficial to simplify the water tank structure 100 and reduce processing and assembly costs.
[0123] In some examples, the specific location of the liquid inlet 100a is not limited in the embodiments of this disclosure. For example, the liquid inlet 100a may be located in the area near the top of the first water tank 110 or the second water tank 120, so that when liquid enters the first water tank 110, the liquid is less likely to quickly exceed the height of the liquid inlet 100a, thereby preventing the liquid from blocking the liquid inlet 100a and increasing the liquid inlet resistance.
[0124] See also some of the possible implementation methods. Figure 1 and Figure 2 As shown, in this embodiment of the present disclosure, the liquid outlet 100b is disposed on one of the first water tank 110 and the second water tank 120. The first water tank 110 and the second water tank 120 share the same liquid outlet 100b.
[0125] In this embodiment, the liquid in the first water tank 110 and the second water tank 120 can be discharged through the outlet hole 100b. Since the first water tank 110 and the second water tank 120 are connected and the liquid is fluid, the first water tank 110 and the second water tank 120 can share the same outlet hole 100b. Specifically, taking the outlet hole 100b as an example where the outlet hole 100b is located in the first water tank 110, in response to the liquid in the first water tank 110 being discharged outward through the outlet hole 100b, the liquid in the second water tank 120 can enter the first water tank 110 and be discharged through the outlet hole 100b of the first water tank 110.
[0126] Since each of the first water tank 110 and the second water tank 120 has a liquid outlet 100b, the number of liquid outlet pipes corresponds to the number of liquid outlet 100b. Therefore, in this embodiment of the present disclosure, by setting the first water tank 110 and the second water tank 120 to share a single liquid outlet 100b, the possibility of multiple liquid outlets 100b and multiple liquid outlet pipes occupying space in the cleaning equipment can be reduced, and it is also beneficial to simplify the water tank structure 100 and reduce processing and assembly costs.
[0127] In some examples, the specific location of the liquid outlet 100b is not limited in the embodiments of this disclosure. Exemplarily, the liquid outlet 100b may be located in the region near the bottom of the first water tank 110 or the second water tank 120, so that the liquid at the bottom of the first water tank 110 or the second water tank 120 can flow out more easily through the liquid outlet 100b, reducing the possibility of residual liquid at the bottom of the first water tank 110 or the second water tank 120.
[0128] See also some of the possible implementation methods. Figure 1 and Figure 2 As shown, in this embodiment of the present disclosure, one of the first water tank 110 and the second water tank 120 is a main water tank. The other of the first water tank 110 and the second water tank 120 is a secondary water tank. The main water tank is provided with a liquid outlet 100b. The water tank structure 100 also includes a conveying device 140. The conveying device 140 communicates with the liquid outlet 100b. The conveying device 140 discharges liquid from the first water tank 110 and the second water tank 120.
[0129] In this embodiment of the present disclosure, the liquid in the first water tank 110 and the second water tank 120 can be discharged through the conveying device 140 for use in supplying liquid to the cleaning equipment. Since the first water tank 110 and the second water tank 120 share the same outlet 100b, the liquid in both tanks can enter the conveying device 140 through the outlet 100b and be output by the conveying device 140.
[0130] The liquid in the first water tank 110 and the second water tank 120 can be used, but is not limited to, to supply liquid to cleaning components such as rags and rollers of the cleaning equipment.
[0131] In some examples, the conveying device 140 can actively drain the liquid from the first water tank 110 and the second water tank 120. Exemplarily, the conveying device 140 may include a water pump 141. The conveying device 140, via the water pump 141, can draw liquid from the first water tank 110 and the second water tank 120 to improve the liquid supply efficiency of the first water tank 110 and the second water tank 120. Furthermore, the conveying device 140 can also easily convey the liquid at the bottom of the first water tank 110 and the second water tank 120 to cleaning equipment to improve the utilization rate of the liquid in the first water tank 110 and the second water tank 120.
[0132] The first water tank 110 and the second water tank 120 can be distinguished as a main water tank and a secondary water tank, respectively. The tank with the liquid inlet 100a can serve as the main water tank. The main water tank is primarily used to supply liquid to the cleaning equipment. When the water tank structure 100 supplies liquid to the cleaning equipment, the liquid in the main water tank can first be supplied to the cleaning equipment through the liquid outlet 100b. When the liquid in the main water tank is insufficient, the liquid in the secondary water tank can be supplied to the cleaning equipment through the liquid outlet 100b of the main water tank.
[0133] In some examples, the delivery device 140 may include a first delivery pipe 142 and a second delivery pipe 143. One end of the first delivery pipe 142 may be connected to a liquid outlet 100b. The other end of the first delivery pipe 142 may be connected to a water pump 141. One end of the second delivery pipe 143 may be connected to the water pump 141. The other end of the second delivery pipe 143 may correspond to a cleaning component of a cleaning device for supplying liquid to the cleaning component.
[0134] In some examples, the inlet port 100a can be located in the main water tank. When filling the water tank structure 100 with water, the liquid can first enter the main water tank and then enter the auxiliary water tank via the main water tank.
[0135] See also some of the possible implementation methods. Figure 1 , Figure 2 and Figure 4 As shown, in this embodiment of the present disclosure, the liquid outlet 100b is located on the side of the main water tank away from the surface to be cleaned. The water tank structure 100 also includes a liquid guide pipe 150. The liquid guide pipe 150 is located inside the main water tank. One end of the liquid guide pipe 150 is lower than a preset position of the main water tank. The other end of the liquid guide pipe 150 is connected to the liquid outlet 100b.
[0136] In this embodiment, since the liquid outlet 100b is located on the side of the main water tank away from the surface to be cleaned, the liquid at the bottom of the main water tank can be drawn by the liquid guide pipe 150, thereby improving the utilization rate of the liquid at the bottom of the main water tank and reducing the possibility of residual liquid at the bottom of the main water tank.
[0137] Specifically, one end of the liquid guide tube 150 can be close to or extend into the liquid at the bottom of the main water tank. Through the suction force of the conveying device 140, the liquid at the bottom of the main water tank can be sucked to improve the utilization rate of the liquid in the main water tank.
[0138] It should be noted that the preset position can refer to a location inside the main water tank near the bottom wall. There is a gap between the preset position and the bottom wall of the main water tank to reduce the possibility that one end of the liquid guide pipe 150 is connected to the bottom wall of the main water tank, which could lead to the bottom wall blocking one end of the liquid guide pipe 150 and causing the liquid guide pipe 150 to fail.
[0139] See also some of the possible implementation methods. Figure 1 and Figure 2 As shown, the first water tank 110 and the second water tank 120 are respectively provided with liquid guiding holes 100d. The water tank structure 100 also includes a liquid pipeline 160. The two ends of the liquid pipeline 160 are connected to the liquid guiding holes 100d of the first water tank 110 and the second water tank 120, respectively. Among them, the horizontal height of the liquid guiding hole 100d on the main water tank is lower than the horizontal height of the liquid guiding hole 100d on the auxiliary water tank.
[0140] In this embodiment, the first water tank 110 and the second water tank 120 can be connected by a liquid pipeline 160. The liquid in the first water tank 110 can flow to the second water tank 120 through the liquid pipeline 160, and the liquid in the second water tank 120 can flow to the first water tank 110 through the liquid pipeline 160, thereby enabling the first water tank 110 and the second water tank 120 to share the same liquid inlet 100a and the same liquid outlet 100b.
[0141] Since the inlet 100a and outlet 100b can be located in the main water tank, when supplying liquid to the cleaning equipment, the liquid in the auxiliary water tank needs to flow out through the outlet 100b of the main water tank. Therefore, by setting the horizontal height of the liquid guide hole 100d of the main water tank lower than that of the liquid guide hole 100d of the auxiliary water tank, the liquid in the auxiliary water tank can flow into the main water tank more easily. This also reduces the amount of liquid remaining at the bottom of the auxiliary water tank, thus improving the utilization rate of the liquid within it.
[0142] See also some of the possible implementation methods. Figure 1 and Figure 2 As shown, the first water tank 110 and the second water tank 120 are respectively provided with connecting holes 100e. The water tank structure 100 also includes a gas pipeline 170. The two ends of the gas pipeline 170 are respectively connected to the connecting holes 100e of the first water tank 110 and the second water tank 120.
[0143] In this embodiment, the top spaces of the first water tank 110 and the second water tank 120 are permeable to each other. Therefore, during the water filling process, the possibility of gas becoming trapped in the first water tank 110 and the second water tank 120, preventing them from being filled, can be effectively reduced.
[0144] The gas in the first water tank 110 and the second water tank 120 can be connected through the gas pipeline 170. When the gas pressure in the first water tank 110 and the second water tank 120 is unstable, it can be balanced through the gas pipeline 170 and the overflow structure 130. Thus, the gas pressure of the first water tank 110, the second water tank 120 and the external environment can tend to be balanced, thereby enabling the water tank structure 100 to provide stable liquid supply to the cleaning equipment.
[0145] When the liquid in the first water tank 110 and the second water tank 120 does not exceed a preset capacity, the gas pipeline 170 can be used to balance the gas pressure in the first water tank 110 and the second water tank 120. When the liquid in the first water tank 110 and the second water tank 120 exceeds the preset capacity, the liquid can flow through the gas pipeline 170 in the first water tank 110 and the second water tank 120, and flow out to the outside of the first water tank 110 and the second water tank 120 through the overflow structure 130.
[0146] In some examples, the horizontal height of the connecting hole 100e can be higher than the horizontal height of the liquid guiding hole 100d. Since the gas has a lower density, the gas will naturally flow upward, while the liquid will flow downward under its own gravity. Therefore, the fact that the horizontal height of the connecting hole 100e is higher than the horizontal height of the liquid guiding hole 100d allows the airflow to flow more easily within the first water tank 110 and the second water tank 120.
[0147] In some examples, the connecting hole 100e on the main water tank can be close to the overflow hole 100c. Therefore, gas or liquid flowing out of the overflow hole 100c can enter the overflow hole 100c through a shorter path and flow out to the outside of the water tank structure 100 through the overflow pipe 131 connected to the overflow hole 100c.
[0148] In some possible implementations, there are multiple first water tanks 110 and / or multiple second water tanks 120.
[0149] When there are multiple first water tanks 110, the multiple first water tanks 110 are connected to each other, and the multiple first water tanks 110 are connected to the second water tank 120. When there are multiple second water tanks 120, the multiple second water tanks 120 are connected to each other, and the multiple second water tanks 120 are connected to the first water tank 110.
[0150] In this embodiment, the number of the first water tank 110 and the second water tank 120 can be set according to the usage requirements of the cleaning equipment and the layout of each functional module on the cleaning equipment.
[0151] Since there are multiple first water tanks 110, the liquid supply to the cleaning equipment can be increased, thereby improving the cleaning efficiency and effect on the surface to be cleaned. Furthermore, by setting multiple first water tanks 110, the overall size of each tank is relatively small. Therefore, the space dispersed on the cleaning equipment can be rationally utilized to arrange more first water tanks 110, thus meeting the sufficient liquid supply requirements of the cleaning equipment.
[0152] Similarly, when there are multiple second water tanks 120, the liquid supply to the cleaning equipment can be increased, thereby improving the cleaning efficiency and effect on the surface to be cleaned. Furthermore, by setting multiple second water tanks 120, and considering their relatively small overall size, more space can be utilized on the cleaning equipment to accommodate more second water tanks 120, thus meeting the equipment's sufficient liquid supply requirements.
[0153] In some examples, when there are multiple first water tanks 110 and / or second water tanks 120, one of the first water tanks 110 or the second water tank 120 can serve as the main water tank of the water tank structure 100. An inlet 100a, an outlet 100b, and an overflow 100c can be provided on the main water tank.
[0154] In some feasible embodiments, multiple first water tanks 110 and multiple second water tanks 120 may share a single inlet port 100a. Multiple first water tanks 110 and multiple second water tanks 120 may share a single outlet port 100b. Multiple first water tanks 110 and multiple second water tanks 120 may share a single overflow port 100c.
[0155] In this embodiment of the present disclosure, multiple first water tanks 110 and second water tanks 120 are connected to each other. Thus, multiple first water tanks 110 and second water tanks 120 can share the same inlet port 100a, the same outlet port 100b, and the same overflow port 100c. This can save the space occupied by the inlet port 100a, outlet port 100b, overflow port 100c and the corresponding pipelines on the cleaning equipment, which is conducive to reserving more space for more functional modules and improving the functional diversity of the cleaning equipment.
[0156] This disclosure provides a cleaning device, which may include a chassis body 200 and a water tank structure 100 as described in any of the above embodiments. The water tank structure 100 may be disposed on the chassis body 200.
[0157] In this embodiment, the water tank structure 100 of the cleaning equipment may include a split first water tank 110 and a second water tank 120. Therefore, the sizes of the first water tank 110 and the second water tank 120 can be set relatively small so that they can be arranged in the dispersed space of the chassis body 200. Thus, while meeting the liquid supply requirements, the water tank structure 100 can not easily occupy a large space of the chassis body 200, and more functional modules can be arranged in the saved space, which is beneficial to improving the functionality of the cleaning equipment.
[0158] This disclosure provides a cleaning system that may include a base station and cleaning equipment. The cleaning equipment may be placed on the base station.
[0159] The base station can have a charging function. When cleaning equipment is placed on the base station, the base station can charge the cleaning equipment.
[0160] Base stations can also have cleaning functions. When cleaning equipment is placed on a base station, it can clean the cleaning modules such as roller brushes, cloths, and side brushes on the equipment.
