[0036] The present invention solves the problem of low cleaning efficiency existing in the cleaning equipment in the prior art.

[0037] Embodiment 1

[0038] This embodiment provides a liquid circulation structure. As Figures 1 to 6 shown, the liquid circulation structure includes a liquid storage tank 20, a flow-through pipe, and an energy storage heating device 10. The first end of the flow-through pipe is communicatively connected to the liquid storage tank 20. The energy storage heating device 10 includes a first housing 200 and a heat storage element 500 for heating the flow-through pipe. The first housing 200 has an accommodation cavity, at least a part of the flow-through pipe and the heat storage element 500 are installed inside the accommodation cavity, and the heat storage element 500 has a heat storage function.

[0039] Specifically, the liquid flow structure includes a liquid storage tank 20, a flow-through pipe, and an energy storage heating device 10. The liquid storage tank 20 is used to supply liquid to the flow-through pipe, so that the part of the flow-through pipe accommodated in the accommodation cavity of the machine body is heated by the heat storage member 500 of the energy storage heating device. The heat storage member 500 has a heat storage function. After the heat storage member 500 is heated, the heat storage member 500 stores the heat energy. The heat storage member 500 storing the heat energy can heat the flow-through pipe. When it is necessary for the flow-through pipe to flow hot liquid, hot liquid passes through the second end of the flow-through pipe and is transported to the cleaning assembly 30 of the cleaning device, so that the cleaning assembly 30 can use the hot liquid to clean the surface to be cleaned. When hot liquid is needed, the heat storage member 500 after heat storage can heat the flow-through pipe without being powered on, so as to clean the stains on the surface to be cleaned with hot water and improve the cleaning efficiency of the liquid.

[0040] Further, the first housing 200 includes a base and a cover plate. The base and the cover plate are detachably connected. A first through hole is formed in the cover plate, and a second through hole is formed in the base. The second end of the flow-through pipe extends into the second through hole through the first through hole, so that at least a part of the flow-through pipe is accommodated inside the accommodation cavity, which is convenient for the heat storage member 500 to heat the flow-through pipe.

[0041] It should be noted that the first housing 200 can be made of steel plate material or any other rigid material.

[0042] In this embodiment, a heat insulation layer is provided on the surface of the first housing 200. The heat insulation layer can be provided on the outer surface of the first housing 200, or the heat insulation layer can also be provided on the outer surface of the first housing 200. The heat insulation layer is made of heat insulation material, for example, it can be ZS-1 high-temperature resistant isolation and heat insulation material.

[0043] As Figure 2 and Figure 6 shown, a power interface 600 is provided on the first housing 200. The heating element 300 is electrically connected to the power interface 600. The power interface 600 is powered on to enable the heat storage member 500 to store heat, and the heat storage member 500 continuously heats the flow-through pipe after power-off.

[0044] Specifically, when the power interface 600 is electrically connected to the power supply, the power supply starts to enable the heat storage member 500 to store heat. The heat storage member 500 after heat storage can still heat the flow-through pipe by heat transfer when powered off.

[0045] Further, the power interface 600 is provided on one of the side walls of the first housing 200, and the heat storage member 500 can be stored in heat in real time by connecting to an external power supply to the power interface 600.

[0046] Of course, it is also possible to install a power source on the first housing 200. The power source is connected to the power interface 600 to supply power to the heating element 300, so as to realize the heat storage of the heat storage element 500.

[0047] In this embodiment, the heat storage element 500 is filled in the accommodating cavity, so that the part of the overcurrent pipe located in the accommodating cavity is immersed in the heat storage element 500. The heat storage element 500 may include one or more of alloy powder, magnesium oxide, sand, ceramic particles, etc.

[0048] As Figures 4 to 6 As shown, the energy storage heating device further includes a heating element 300. The heating element 300 is connected to the power interface 600. At least a part of the heating element 300 is immersed in the heat storage element 500, so as to heat the heat storage element 500 through the heating element 300 when the power interface 600 is powered on. The power interface 600 is used to connect to a power source.

[0049] Specifically, the heating element 300 converts electrical energy into heat energy, and the heating element 300 heats the heat storage element 500 to realize the heat storage of the heat storage element 500.

[0050] Furthermore, the heating structure of the heating element 300 is not limited to this, and it can also be other types of heating structures, as long as the effect of electric heating can be achieved, such as resistance wires, heating sheets, etc.

[0051] As Figures 4 to 6 As shown, the heating element 300 is arranged along the circumferential direction of the first housing 200. The heating element 300 includes a plurality of sub-heating elements formed by bending, and the sub-heating elements are arranged in sequence along the first direction.

[0052] Specifically, the plurality of sub-heating elements form a multi-layer structure along the first direction. By bending and forming a multi-layer structure, the contact area between the heating element 300 and the heat storage element 500 is increased, the efficiency of the heating element 300 heating the heat storage element 500 is improved, and the heat storage efficiency of the heat storage element 500 is improved. Among them, the first direction can be a direction parallel to the bottom and / or top of the first housing 200, or any other direction.

[0053] Furthermore, the heating element 300 is arranged close to the side wall of the accommodating cavity relative to the center of the accommodating cavity, so as to reserve a space for accommodating the overcurrent pipe at the center of the accommodating cavity, and the heating element 300 surrounds the outer periphery of the space.

[0054] It should be noted that the pipe diameter, length, and size of the space of the heating element 300 can all be adaptively adjusted according to actual needs.

[0055] As Figure 4As shown, the energy storage heating device further includes a heating fin 400. The heating fin 400 is installed inside the accommodating cavity, and at least a part of the heating fin 400 is immersed inside the heat storage member 500. The heating member 300 extends into the heating fin 400.

[0056] Specifically, the heating member 300 extends into the heating fin 400 to heat the heat storage member 500 through the heating fin 400. Since the contact area between the heating fin 400 and the heat storage member 500 is large, when the power interface 600 is powered on, the heating member 300 heats the heating fin 400, and the heating fin 400 can quickly heat the heat storage member 500. By setting the heating fin 400, the heat storage efficiency of the heat storage member 500 is improved.

[0057] Further, the heating fin 400 is arranged along the circumferential direction of the first housing 200 to form a U-shaped structure.

[0058] Of course, the heating fin 400 can also be a structure of other shapes, specifically based on improving the contact area with the heat storage member 500, such as a □-shaped structure, etc.

[0059] As Figure 1 shown, the overflow pipe includes a first external section 1010 and an internal section 1020. The first external section 1010 is located outside the energy storage heating device 10, and the internal section 1020 is accommodated inside the accommodating cavity. The internal section 1020 includes at least one sub-pipeline. When there are multiple sub-pipelines, the multiple sub-pipelines are arranged in parallel.

[0060] Specifically, the overflow pipe is arranged in two sections. The overflow pipe located outside the accommodating cavity is the first external section 1010, and the overflow pipe located inside the accommodating cavity is the internal section 1020. The heat storage member 500 can heat the internal section 1020 to raise the temperature of the liquid inside the internal section 1020, and the heated liquid can flow into the second end of the first external section 1010, that is, the overflow pipe.

[0061] Further, the first external section 1010 includes two parts. One part is arranged between the liquid storage tank 20 and the energy storage heating device 10, and the other part is arranged outside the energy storage heating device 10.

[0062] Further, multiple sub-pipelines are immersed inside the heat storage member 500, which increases the contact area between the heat storage member 500 and the internal section 1020, improves the efficiency of the heat storage member 500 heating the internal section 1020, and further improves the efficiency of the heat storage member 500 heating the liquid inside the overflow pipe.

[0063] It should be noted that the internal pipe can be made of a metal material to ensure the heat conductivity of the internal pipe and improve the heat conduction efficiency. It can also be made of any material with excellent heat conduction performance, and the present application does not limit this.

[0064] As Figure 6 and Figure 7 shown, each sub-pipeline is bent multiple times to form a detour pipeline structure, so as to increase the contact area between the sub-pipeline and the heat storage member 500.

[0065] Furthermore, multiple sub-pipelines are arranged in sequence along the circumferential direction of the first housing 200. Preferably, the multiple sub-pipelines are arranged at equal intervals to be evenly arranged inside the heat storage member 500, so as to improve the heating efficiency of the heat storage member 500.

[0066] As Figure 4 Figure 6 and Figure 7 shown, the energy storage heating device 10 further includes a first water distributor 700 and a second water distributor 800. The first water distributor 700 is installed on the first housing 200. The first liquid inlet of the first water distributor 700 is communicated with the first external section 1010. The first water distributor 700 has at least one first liquid outlet 702, and the first liquid outlet 702 is communicated with one end of the sub-pipeline. The second water distributor 800 is installed on the first housing 200. The second water distributor 800 has at least one second liquid inlet. The second liquid inlet of the second water distributor 800 is communicated with the other end of the sub-pipeline. The second liquid outlet of the second water distributor 800 extends to the outside of the first housing 200.

[0067] Specifically, the built-in section 1020 and the first external section 1010 are connected through the first water distributor 700, so that the liquid in the first external section 1010 uniformly flows into the multiple sub-pipelines of the built-in section 1020; the built-in section 1020 and the second external section 1030 are connected through the second water distributor 800, so as to enable the liquid in the multiple sub-pipelines to flow into the second external section 1030 through the second water distributor 800.

[0068] In this embodiment, a heat insulation layer is provided on the surface of the first housing 200. By providing the heat insulation layer on the first housing 200, the heat insulation effect is improved. In the power-off state, the heat storage member 500 can have the effect of heating the flow-through pipe for a long time. When the heat insulation layer is provided on the inner surface of the first housing 200, the heat insulation layer can reduce the corrosion of the first housing 200 by the temperature and the heat storage member 500.

[0069] Among them, the heat insulation layer can be provided on the inner surface of the first housing 200, or on the outer surface of the first housing 200, or on a partial surface of the first housing 200.

[0070] In this embodiment, the heat insulation layer material is ZSZ-1 high-temperature resistant heat insulation material.

[0071] As Figure 4As shown, the energy storage heating device 10 further includes a second housing 100 and a heat insulation member. The first housing 200 is installed inside the second housing 100. There is an installation gap 900 between the second housing 100 and the first housing 200, and the heat insulation member is accommodated inside the installation gap 900.

[0072] As Figure 4 shown, the first housing 200 may include an upper cover 210, a base 220, and a lower cover 230. The upper cover 210 and the lower cover 230 may be provided to bulge away from the base 220. The upper cover 210, the base 220, and the lower cover 230 may be integrally formed or may be formed as a split structure. The first water distributor 700 may be provided inside the upper cover 210, and the second water distributor 800 may be provided inside the lower cover 230.

[0073] A first through hole may be formed in the upper cover 210. The connecting portion of the first external section 1010 may extend through the first through hole into the upper cover and be connected to the first water distributor 700. Similarly, a second through hole may be formed in the lower cover 230. The connecting portion of the second external section 1030 extends through the second through hole into the lower cover 230 and is connected to the second water distributor 800.

[0074] As Figure 6 shown, the first water distributor 700 is provided with a first flow channel 701 and a plurality of first liquid outlets 702 communicated with the first flow channel 701. The plurality of first liquid outlets 702 are equally spaced on the first water distributor 700. The second water distributor 800 is provided with a second flow channel and a plurality of second liquid inlets communicated with the second flow channel. The plurality of second liquid inlets are equally spaced on the second water distributor 800.

[0075] In this embodiment, preferably, the first flow channel 701 is provided with two, and the two first flow channels 701 are cross - arranged in a cross shape on the first water distributor 700. The first water distributor 700 is provided with four first liquid outlets 702. The four first liquid outlets 702 are equally spaced along the circumference of the first water distributor 700 and are respectively located at the four ends of the cross - shaped first flow channel 701. Similarly, the second flow channel is provided with two, and the two second flow channels are cross - arranged in a cross shape on the second water distributor 800. The second water distributor 800 is provided with four second liquid inlets. The four second liquid inlets are equally spaced along the circumference of the second water distributor 800 and are respectively located at the four ends of the cross - shaped second flow channel. Four sub - pipelines are correspondingly provided. One ends of the four sub - pipelines are connected to the second liquid inlets of the second water distributor 800, and the other ends of the four sub - pipelines are connected to the first liquid outlets 702 of the first water distributor 700.

[0076] After the liquid enters the interior of the first flow channel 701 from the first liquid inlet of the first water separator 700, the liquid flows evenly and in equal amounts through the first liquid outlet 702 to the sub-pipes, and the liquid flows through multiple sub-pipes to multiple second liquid inlets of the second water separator 800 and then converges in the second flow channel. The converged liquid flows out of the second water separator 800 through the second liquid outlet of the second water separator 800 and enters the second external section 1030.

[0077] Of course, the structures of the first water separator 700 and the second water separator 800 are not limited to the above structures. The water separator can also be provided with different numbers of flow channels and liquid passing holes communicated with the flow channels, as long as the effect of uniform flow distribution can be achieved.

[0078] It should be noted that the structures of the first water separator 700 and the second water separator 800 can be the same or different, as long as the first water separator 700 can achieve flow distribution so that the liquid flows evenly to multiple sub-pipes, and the liquid inside the multiple sub-pipes converges and flows out through the second water separator 800. The number and shape of the flow channels, as well as the number and positions of the liquid inlets and outlets, can be adjusted adaptively.

[0079] Specifically, by placing a heat insulation member at the installation gap 900, heat loss of the heat storage member 500 inside the first housing 200 can be avoided, and at the same time, phenomena such as scalding can also be prevented.

[0080] In this embodiment, the customized temperature can be comprehensively adjusted by adjusting the size parameters of the heating member 300, the size parameters of the heating fins 400, the material of the heat storage member 500, and the contact area between the sub-pipes and the heat storage member 500.

[0081] Embodiment 2

[0082] This embodiment provides a cleaning device, as Figure 1 shown. The cleaning device includes a machine body, the liquid flow structure in Embodiment 1, a cleaning component 30, and a control component. The energy storage heating device 10 and the liquid storage tank 20 of the liquid flow structure are installed on the machine body; the cleaning component 30 is installed on the machine body, and the cleaning component 30 is communicated with the second end of the flow-through pipe and the liquid storage tank 20; the control component at least includes a controller, and the controller is electrically connected to the cleaning component 30.

[0083] Specifically, the liquid circulation structure is a part of the cleaning device, which can spray hot liquid to the cleaning component 30 under the control of the control component when needed, so that the cleaning device has the function of discharging hot liquid. When cleaning the surface to be cleaned, when there are difficult-to-clean stains on the surface to be cleaned, the over-flow pipe heated by the energy storage heating device 10 of the liquid circulation structure provides hot liquid to the cleaning component 30, realizing that the cleaning device can provide hot liquid to the cleaning component 30 without setting a separate hot water tank during the cleaning operation, and without setting a separate power supply for heating.

[0084] Further, the cleaning component 30 includes a cleaning member, the cleaning member is movably installed on the body, and a driving motor is also arranged on the body. Under the driving action of the driving motor, the cleaning member can clean the surface to be cleaned.

[0085] Further, the controller further includes a temperature sensor, the temperature sensor is installed on the body, and the temperature sensor can detect the temperature of the liquid inside the water pipe in real time.

[0086] As Figure 1 shown, the control component includes a first switch 40, a second switch 60, a first water pump 50 and a second water pump 70. A first water path and a second water path are formed in the cleaning device. Among them, the first water path includes a communication pipe, and both ends of the communication pipe are directly communicated with the liquid storage tank 20 and the cleaning component 30; the second water path includes an over-flow pipe, which communicates the liquid storage tank 20, the cleaning component 30 and the energy storage heating device 10.

[0087] The first switch 40 is arranged on the second water path for controlling the on and off of the second water path; the first water pump 50 is also arranged on the second water path for pumping the liquid in the liquid storage tank 20 into the energy storage heating device, so that the energy storage heating device conveys the heated liquid to the cleaning component 30 of the cleaning device.

[0090] In this embodiment, a storage battery is arranged on the cleaning device, and the storage battery can be electrically connected to the power interface 600 as a power source to heat the heating element 300.

[0091] Embodiment 3

[0092] This embodiment provides a cleaning control method, which uses the cleaning device in Embodiment 2 to execute the cleaning control method. The cleaning control method includes responding to receiving a first cleaning instruction and responding to receiving a second cleaning instruction.

[0093] Specifically, during the process of responding to receiving the first cleaning instruction, the control liquid storage tank 20 supplies water to the overflow pipe, so that the overflow pipe conveys the liquid heated by the energy storage heating device to the cleaning component 30 of the cleaning device. Among them, the first switch 40 is in an open state, and the second switch 60 is in a closed state, so as to heat the liquid inside the overflow pipe by heating the energy storage device. The heated liquid flows towards the cleaning component 30 under the action of the first water pump 50, so as to supply hot liquid to the cleaning component 30.

[0094] It should be noted that when the cleaning device recognizes a preset stain on the surface to be cleaned, it can generate a first cleaning instruction, so that the cleaning device provides hot water to the cleaning component 30 to improve the cleaning efficiency.

[0095] Specifically, the stain types that need to be cleaned with hot water can be pre-stored on the storage mechanism of the cleaning device. When the camera and / or sensor of the cleaning device recognize that the stain on the surface to be cleaned conforms to the pre-stored stain types, a corresponding first cleaning instruction can be generated. Of course, a corresponding control mechanism can also be set on the cleaning device, so that the user operates the control mechanism and issues a corresponding first cleaning instruction.

[0096] Further, the cleaning device further includes a connecting pipe, and both ends of the connecting pipe are respectively connected to the liquid storage tank 20 and the cleaning component 30. During the process of responding to receiving the second cleaning instruction, the control liquid storage tank 20 supplies water to the connecting pipe, so that the connecting pipe conveys water to the cleaning component 30 of the cleaning device. Among them, the second switch 60 is in an open state, and the first switch 40 is in a closed state. The liquid in the liquid storage tank 20 of the cleaning device flows towards the cleaning component 30 of the cleaning device through the second water pump 70 of the control component, so as to supply normal temperature water to the cleaning component 30.

[0097] Specifically, the second cleaning instruction can be issued by the user operating the control mechanism or generated by any other means, which will not be elaborated here.

[0098] In this embodiment, when the cleaning component 30 needs to be supplied with warm water, the cleaning device can also execute the first cleaning instruction and the second cleaning instruction simultaneously. At this time, both the first switch 40 and the second switch 60 are in an open state, and the flow rate of the controllable liquid is controlled by controlling the first water pump 50 and the second water pump 70, and then the final temperature of the liquid flowing to the cleaning part is controlled.

[0099] Embodiment 4

[0100] This embodiment provides a cleaning system, which includes the cleaning device and the base in Embodiment 2.

[0101] Specifically, a power supply is provided on the base. When the cleaning device moves onto the base, the power supply is electrically connected to the power interface 600 of the energy storage heating device of the liquid circulation structure of the cleaning device. The power supply realizes power supply to the heating element 300 through the power interface 600. During the power-on process, the heating element 300 converts electrical energy into heat energy. The heating element 300 transfers the heat energy to the heat storage element 500 to realize heating of the heat storage element 500 by the heating element 300. The heat storage element 500 can store heat energy to achieve the effect of heat storage.

[0102] Meanwhile, the power supply can supply power to the battery of the cleaning device so that the battery can store energy.

[0103] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0104] 1. The heat storage element 500 has a heat storage function. After the heat storage element 500 is heated, the heat storage element 500 stores the heat energy. The heat storage element 500 storing the heat energy can heat the flow-through pipe so that when hot liquid needs to flow through the flow-through pipe, hot liquid can pass through the second end of the flow-through pipe. When hot liquid is needed, the heat storage element 500 after heat storage can heat the flow-through pipe without power supply to clean the stains on the surface to be cleaned with hot water, improving the cleaning efficiency of the liquid and enhancing the user experience.

[0105] 2. A heat insulation layer is provided on the first housing 200, improving the heat insulation effect of the heat storage element 500 inside the first housing 200 and at the same time enabling the first housing 200 to have an anti-corrosion function.

[0106] 3. The installation gap 900 between the first housing 200 and the second housing 100 is filled with a heat insulation member, further strengthening the heat insulation effect of the first housing 200 and at the same time avoiding the phenomenon of getting burned.

[0107] 4. Multiple sub-pipes are provided to increase the contact area between the sub-pipes and the heat storage element 500 and increase the heating efficiency.

[0108] Obviously, the above-described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, those of ordinary skill in the art can make other different forms of changes or modifications without creative efforts, and all should fall within the protection scope of the present invention.
