Abstract

The application provides a liquid spraying assembly, a cleaning device and a cleaning appliance. The first liquid inlet pipeline and the second liquid inlet pipeline of the liquid spraying assembly are connected to the liquid outlet pipeline. The first liquid inlet pipeline is in communication with the first liquid storage container, and the second liquid inlet pipeline is in communication with the second liquid storage container. The liquid spraying assembly has a first mode and a second mode. In the first mode, the liquid outlet pipeline sprays the first cleaning medium. In the second mode, the liquid outlet pipeline sprays the second cleaning medium. The emptying member is used to at least empty the cleaning medium in the liquid outlet pipeline. The controller is configured to control the emptying member to empty the cleaning medium in the liquid outlet pipeline after one of the first mode and the second mode ends and before the other one starts. Different liquid inlet pipelines output different cleaning media to the liquid outlet pipeline, realizing the output of different cleaning media. When it is necessary to replace the spraying of different cleaning media, the emptying member empties the cleaning medium in the liquid outlet pipeline, avoiding the mixing of the two cleaning media and causing the cleaning effect to decrease.

Detailed Implementation

[0036] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0037] It should be noted that when a component is referred to as being "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0038] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0039] It's important to know that floor scrubbers, as common cleaning equipment, are widely used in various scenarios such as homes, offices, and commercial areas. In related technologies, floor scrubbers are equipped with a spray structure that sprays cleaning fluid onto the floor to improve cleaning effectiveness. However, current spray structures often only spray a single type of cleaning fluid, which cannot meet the cleaning needs of different scenarios. For example, different scenarios may require different types of cleaning fluids, such as acidic cleaning fluids, alkaline cleaning fluids, water, and foam cleaning fluids. For example, acidic cleaning fluids can be used when alkaline stains are present on the surface to be cleaned, or hypochlorous acid cleaning fluids can be used when disinfection is needed; conversely, alkaline cleaning fluids can be used when acidic stains are present.

[0040] Based on this, this application improves the spraying components, cleaning tools and cleaning equipment in the related technology.

[0041] Please see Figure 1 and Figure 2 , Figure 1A schematic diagram of the liquid spraying assembly provided in an embodiment of this application is shown. Figure 2 This illustration shows a schematic diagram of the structure of a cleaning device provided in an embodiment of this application. In this embodiment, a spraying assembly is used as an example on the cleaning device. The spraying assembly includes a first liquid storage container, a second liquid storage container, and a spraying pipeline. The first liquid storage container stores a first cleaning medium; the second liquid storage container stores a second cleaning medium, which is different from the first cleaning medium; the spraying pipeline includes a first inlet pipeline, a second inlet pipeline, and an outlet pipeline; the first inlet pipeline and the second inlet pipeline are both connected to the outlet pipeline; the first inlet pipeline and the first liquid storage container... The device is connected, and the second inlet pipe is connected to the second storage container; the spraying assembly has a first mode and a second mode. In the first mode, the outlet pipe is connected to the first inlet pipe and is used to spray out the first cleaning medium; in the second mode, the outlet pipe is connected to the second inlet pipe and is used to spray out the second cleaning medium; the draining device is connected to the spraying pipe and is used to at least drain the cleaning medium in the outlet pipe; the controller is connected to the draining device, and the controller is configured to control the draining device to at least drain the cleaning medium in the outlet pipe during the process of finishing one of the first mode and starting the other.

[0042] It is understood that in this embodiment, the first and second inlet pipes are connected to the outlet pipe, allowing different cleaning media to be sprayed from the same outlet. This saves internal space and optimizes the external structure of the cleaning equipment. The first and second storage containers store different first and second cleaning media, respectively. The dispensing component can select the appropriate media to spray according to the cleaning needs of the equipment, meeting diverse cleaning scenario requirements. Furthermore, a drain device is connected to the spray pipe, and the controller is configured to drain at least the cleaning media from the outlet pipe during the switching between the first and second modes. This helps remove any residual first cleaning media from the outlet pipe during mode switching, preventing the mixing of different cleaning media within the pipe from affecting the cleaning effect (e.g., avoiding acid-base neutralization, foam-liquid mixing reducing foaming efficiency, etc.).

[0043] Please refer to the embodiments described in this application. Figure 2 The venting component in this embodiment includes a first air pump, the output port of which is connected to the liquid spraying pipeline.

[0044] It should be explained that the output port of the first air pump is connected to the liquid spraying pipeline, which can generate positive pressure gas and deliver it to the liquid spraying pipeline through the output port to discharge the cleaning medium remaining in the pipeline.

[0045] Understandably, the connection between the output port of the first air pump and the spray pipeline facilitates the efficient evacuation of the cleaning medium from the spray pipeline using gas pressure. When switching between the first and second modes is required, the first air pump generates positive pressure gas, which enters the spray pipeline (such as the first inlet pipeline, the second inlet pipeline, or the outlet pipeline) through the output port. This gas pushes the residual cleaning medium in the pipeline towards the end of the outlet pipeline and discharges it, ensuring that the residual medium in the pipeline is fully removed. This setup utilizes the fluidity and pressure characteristics of gas to quickly and thoroughly empty the pipeline, preventing residual medium from lingering in the pipeline. This helps reduce the risk of mixing different cleaning media, thereby ensuring the stable performance of the subsequently sprayed cleaning medium.

[0046] In some embodiments of this application, the first cleaning medium is water and the second cleaning medium is a foam generating liquid; or, the first cleaning medium is an acidic cleaning liquid and the second cleaning medium is an alkaline cleaning liquid.

[0047] Understandably, when the first cleaning medium is water and the second cleaning medium is foam-generating liquid, water can meet the need for penetrating and cleaning large areas and stubborn stains, while foam-generating liquid is suitable for scenarios where water accumulation is a concern, such as wooden floors and marble, reducing damage to the floor from liquid residue. The combination of the two media expands the applicability of the cleaning equipment. When the first cleaning medium is an acidic cleaning solution and the second cleaning medium is an alkaline cleaning solution, the acidic cleaning solution can effectively remove alkaline stains such as limescale and urine stains, while the alkaline cleaning solution can specifically remove acidic stains such as juice and coffee, avoiding the problem of a single cleaning medium being ineffective in cleaning stains of different properties, thus improving cleaning efficiency.

[0048] Specifically, by installing a drain device to drain the liquid outlet pipeline, it is beneficial to prevent the mixing of water and foam-generating liquid, which would reduce the foaming effect or cause foam liquid to be present in the clean water. In another case, draining the liquid outlet pipeline through the drain device helps to avoid the neutralization reaction that would occur when acidic and alkaline cleaning solutions are mixed, thus reducing the cleaning ability. This ensures that the cleaning performance of each medium is stable and further enhances the practicality of the spraying assembly.

[0049] Please refer to the embodiments described in this application. Figure 2 , Figure 2 Taking the reuse of the second and first air pumps as an example, in practical applications, the second air pump can also be set up independently. The spraying assembly in this embodiment also includes a second air pump, the output port of which is connected to the second liquid inlet pipe and is used to deliver gas to the second liquid inlet pipe to stimulate the foam generating liquid to generate foam liquid.

[0050] Understandably, the connection between the output port of the second air pump and the second inlet pipe facilitates the efficient generation of foam-generating liquid from the foam-generating liquid. When the second inlet pipe delivers the foam-generating liquid, the second air pump operates and supplies gas into the pipe. The gas mixes with the foam-generating liquid within the pipe, causing it to form foam liquid, ensuring that the foam sprayed from the outlet pipe meets cleaning requirements. Furthermore, the reuse of the second air pump from the first air pump simplifies the overall structure of the spray assembly.

[0051] Please refer to the embodiments described in this application. Figure 2 , Figure 2 Taking the example of the first air pump being connected to the liquid outlet pipeline, in this embodiment the first air pump is connected to at least one of the liquid outlet pipeline, the first liquid inlet pipeline, and the second liquid inlet pipeline.

[0052] Understandably, if the output port of the first air pump is directly connected to the liquid outlet pipe, then when evacuation is required, the first air pump can directly push the residual medium in the liquid outlet pipe to be discharged, thus partially evacuating the spray pipe; if the output port of the first air pump is connected to the first liquid inlet pipe, it can remove the residual medium in the first liquid inlet pipe and the connected liquid outlet pipe after the first mode ends; if it is connected to the second liquid inlet pipe, it can remove the residual medium in the second liquid inlet pipe and the connected liquid outlet pipe after the second mode ends.

[0053] Please refer to the embodiments described in this application. Figure 2 In this embodiment, the output port of the first air pump is connected to the connection between the liquid outlet pipe, the first liquid inlet pipe, and the second liquid inlet pipe.

[0054] Understandably, the arrangement of connecting the output port of the first air pump to the connection point between the liquid outlet pipeline and the first and second liquid inlet pipelines facilitates centralized evacuation of the spray pipeline. When evacuation is required, the positive pressure gas generated by the first air pump enters the connection point through the output port, simultaneously delivering gas to the liquid outlet pipeline, the portion of the first liquid inlet pipeline near the connection point, and the portion of the second liquid inlet pipeline near the connection point. This pushes the residual cleaning medium in these areas towards the end of the liquid outlet pipeline and discharges it, ensuring that there is no residue at the connection point and in the connected critical pipeline sections.

[0055] In some embodiments of this application, the spraying pipeline further includes a solenoid valve, which is disposed at the connection between the outlet pipeline and the first inlet pipeline and the second inlet pipeline. The solenoid valve is used to control the on / off connection between the outlet pipeline and the first inlet pipeline, and to control the on / off connection between the outlet pipeline and the second inlet pipeline.

[0056] Understandably, the solenoid valve is positioned at the connection between the outlet pipe and the first and second inlet pipes, which facilitates precise control of the delivery path of different cleaning media. When the spray assembly is in the first mode, the solenoid valve controls the outlet pipe to connect with the first inlet pipe and disconnect from the second inlet pipe. This allows the first cleaning media to enter the outlet pipe and be sprayed out through the first inlet pipe and its connection, while preventing the first cleaning media from flowing back into the second inlet pipe. When switching to the second mode, the solenoid valve controls the outlet pipe to connect with the second inlet pipe and disconnect from the first inlet pipe. This allows the second cleaning media to enter the outlet pipe and be sprayed out through the second inlet pipe and its connection, while preventing the second cleaning media from flowing back into the first inlet pipe.

[0057] In some embodiments of this application, please refer to Figure 3 , Figure 3 A schematic diagram of the liquid spraying assembly provided in this embodiment is shown; Figure 3 In this embodiment, only the first liquid inlet pipe is provided with a liquid inlet valve as an example; the first liquid inlet pipe and the second liquid inlet pipe are both liquid inlet pipes, and a liquid inlet valve is provided on the liquid inlet pipe. The controller is also used to control the opening / closing of the liquid inlet valve. The controller is used to determine whether the spraying component is in the first mode or the second mode based on the opening / closing of the corresponding liquid inlet valve.

[0058] It should be explained that the inlet valve is a component installed on the inlet pipeline to control the opening and closing of the inlet pipeline, and its opening or closing state is controlled by the controller.

[0059] Understandably, using inlet valves on the inlet lines and having the controller determine the spray assembly's mode (first or second) based on the valve's on / off status facilitates direct determination of the current operating mode via valve position. When the inlet valve on the first inlet line is open and the inlet valve on the second inlet line is closed, the controller identifies it as the first mode; conversely, it identifies it as the second mode. This ensures the intuitiveness and accuracy of mode determination, providing a reliable basis for triggering subsequent evacuation operations.

[0060] In some embodiments, please continue reading Figure 3 , Figure 3 The example only shows that a flow meter is installed on the first liquid inlet pipe; in this embodiment, a flow meter is installed on the liquid inlet pipe, and the controller is also used to determine whether the spraying component is in the first mode or the second mode based on the flow parameters of the corresponding flow meter.

[0061] It should be explained that the flow meter is used to detect the flow parameters of the cleaning medium in the inlet pipeline and feed the parameters back to the controller.

[0062] Understandably, using flow meters on the inlet lines and having the controller determine the mode based on the flow parameters of the corresponding flow meters is beneficial for confirming the mode through actual flow status. In a specific example, when the flow meter on the first inlet line detects flow parameters and there is no flow on the second inlet line, the controller determines it to be in the first mode; otherwise, it determines it to be in the second mode. This determination method is based on the actual delivery status of the medium, improving the objectivity of mode determination and reducing misjudgments caused by valve malfunctions.

[0063] In some embodiments, please continue reading Figure 3 , Figure 3 Taking the example of a first water pump installed on the first liquid inlet pipe; the first water pump is used to pump the cleaning medium in the storage container to the liquid inlet pipe; the controller is also used to determine whether the spraying component is in the first mode or the second mode based on the opening / closing of the corresponding first water pump.

[0064] It should be explained that the first water pump is used to draw cleaning medium from the storage container and pump it into the inlet pipeline, and its working status (on or off) is controlled by the controller.

[0065] Understandably, using a first water pump on the inlet pipeline and setting the controller based on the on / off judgment mode of the corresponding first water pump is beneficial for determining the mode through the status of the power components. In a specific example, when the first water pump is on and the second water pump is off, the controller determines it to be in the first mode; otherwise, it determines it to be in the second mode. By utilizing the direct correlation between the working status of the water pump and the medium delivery, it ensures that the mode judgment is consistent with the actual operating status.

[0066] Specifically, the controller can determine whether the spraying assembly is in the first mode or the second mode by combining the parameters of the flow meter, the first water pump, and the inlet valve.

[0067] In some embodiments of this application, please refer to Figure 4 , Figure 4 A schematic diagram of the liquid spraying assembly provided in this embodiment is shown. Figure 4 Taking the example of a second water pump installed on the first liquid inlet pipe, both the first and second liquid inlet pipes in this embodiment are liquid inlet pipes, and a second water pump is installed on the liquid inlet pipe. The second water pump is used to pump the cleaning medium in the liquid inlet pipe and the liquid outlet pipe back to the liquid storage container.

[0068] Understandably, the second water pump is used to pump the cleaning medium in the inlet and outlet pipelines back to the storage container, which facilitates the recovery and emptying of the cleaning medium in the pipelines through pumping. When the first mode ends and it is necessary to switch to the second mode, the second water pump on the first inlet pipeline starts, pumping the residual first cleaning medium in the first inlet and outlet pipelines back to the first storage container; when the second mode ends and it is necessary to switch to the first mode, the second water pump on the second inlet pipeline starts, pumping the residual second cleaning medium in the second inlet and outlet pipelines back to the second storage container.

[0069] In some embodiments of this application, a first water pump is provided on the liquid inlet pipeline. The first water pump is used to pump the cleaning medium in the liquid storage container to the liquid inlet pipeline. The first water pump is a reversible water pump and is reused with a second water pump.

[0070] It should be explained that a reversible water pump is a water pump that can change its operating direction. When rotating forward, it can pump the cleaning medium in the storage container to the inlet pipe, and when rotating in reverse, it can pump the cleaning medium in the inlet and outlet pipes back to the storage container.

[0071] Understandably, designing the first water pump as a reversible pump that can be reused with the second pump simplifies the piping structure and reduces hardware costs. When the first water pump rotates forward, it draws cleaning medium from the storage container and delivers it to the inlet pipeline, meeting the delivery requirements of cleaning medium in either the first or second mode. When the pipeline needs to be emptied, the first water pump reverses, pumping the remaining cleaning medium in the inlet and outlet pipelines back to the corresponding storage container, thus integrating the functions of pumping the medium and recovering the residual medium.

[0072] In some embodiments of this application, the controller is configured to control the evacuation unit to at least evacuate the cleaning medium from the discharge line before the other of the first and second modes begins.

[0073] It should be explained that the period between the end of the first mode and the start of the second mode can be understood as the intermediate time between the two modes. In the embodiments of this application, "before the start of the other of the first and second modes" refers to the moment when the latter mode is about to be started.

[0074] Understandably, configuring the controller to empty the draining device before the start of either the first or second mode ensures that the cleaning medium is completely removed from the outlet pipeline at critical points during mode switching. This facilitates pipeline cleaning and ensures that no residual cleaning medium from the previous mode remains in the pipeline when the latter mode starts. When switching from the first mode to the second mode, just before the second mode begins, the controller activates the draining device to empty any remaining first cleaning medium from the outlet pipeline, after which the second mode starts and sprays out the second cleaning medium. Similarly, when switching from the second mode to the first mode, just before the first mode begins, the controller activates the draining device to empty any remaining second cleaning medium before starting the first mode.

[0075] Specifically, if the first mode or the second mode is used both times, the purging device does not need to perform a purging action; the purging device is only used to purge the liquid outlet pipeline during the intermediate period between the two times when different modes are selected.

[0076] Furthermore, in order to better implement the spraying assembly in any of the above embodiments, please continue to refer to the following based on the above spraying assembly. Figure 2 This application also provides a cleaning appliance, including a spraying assembly as described above, which is used to spray liquid toward the surface to be cleaned.

[0077] In some embodiments, the cleaning appliance may be a floor scrubber.

[0078] In some embodiments of this application, please refer to Figure 5 , Figure 5 A schematic diagram of the structure of the cleaning device provided in this embodiment is shown. The cleaning device in this embodiment has a forward direction, and the liquid outlet pipe of the spray component is located on the front side of the cleaning device along the forward direction, with the liquid outlet of the liquid outlet pipe facing the surface to be cleaned.

[0079] It should be explained that the forward direction of a cleaning appliance refers to the direction in which the appliance moves forward during cleaning operations, usually determined by the user pushing it or by the appliance's autonomous drive. The front side of the cleaning appliance refers to the front portion of the appliance along the forward direction, which is the side that first contacts the area to be cleaned during the cleaning process.

[0080] Understandably, when the cleaning tool moves in the forward direction, the outlet of the liquid outlet first sprays the cleaning medium onto the surface to be cleaned, so that the medium can pre-wet the area to be cleaned, providing pretreatment for the wiping or scrubbing actions of subsequent cleaning components (such as roller brushes, mops, etc.), and enhancing the softening and decomposition effect on stains.

[0081] Furthermore, in order to better implement the cleaning apparatus in any of the above embodiments, please refer to the following based on the cleaning apparatus described above. Figure 6 , Figure 6A schematic diagram of the structure of the cleaning device provided in this embodiment is shown; this application embodiment also provides a cleaning device, which includes a base and the above-mentioned cleaning appliance, and the base is used to charge the cleaning appliance.
