[0056] In the following description, specific details such as specific system structures and techniques are provided for purposes of illustration rather than limitation to facilitate a thorough understanding of the embodiments of the present application. However, it will be apparent to those skilled in the art that the present application may be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to avoid obscuring the description of the present application with unnecessary detail.

[0057] It will be understood that when used in this specification and the appended claims, the term "comprising" indicates the presence of described features, integers, steps, operations, elements and / or components, but does not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components and / or groups thereof.

[0058] It should also be understood that the terms used in this specification are for the purpose of describing specific embodiments only and are not intended to limit the present application. As used in this specification and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms unless the context clearly indicates otherwise.

[0059] It should be further understood that the term "and / or" used in this specification and the appended claims refers to and includes any and all possible combinations of one or more of the associated listed items.

[0060] As used in this specification and the appended claims, the term "if" can be interpreted as "when" or "upon" or "in response to determining" or "in response to detecting," depending on the context. Similarly, the phrase "if it is determined" or "if [described condition or event] is detected" can be interpreted as meaning "upon determination" or "in response to determining" or "upon detection of [described condition or event]" or "in response to detecting [described condition or event]," depending on the context.

[0061] In a specific implementation, the cleaning equipment described in the embodiments of the present application includes but is not limited to floor scrubbers, floor mops, etc. having touch-sensitive surfaces (e.g., touch screen displays and / or touchpads).

[0062] The various applications that can be executed on the cleaning device can use at least one common physical user interface device, such as a touch-sensitive surface. One or more functions of the touch-sensitive surface and the corresponding information displayed on the cleaning device can be adjusted and / or changed between applications and / or within a corresponding application. In this way, the common physical architecture of the cleaning device (e.g., the touch-sensitive surface) can support a variety of applications with user interfaces that are intuitive and transparent to the user.

[0063] It should be understood that the size of the serial numbers of each step in this embodiment does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiment of this application.

[0064] The cleaning equipment may be a floor scrubber, a floor mop, or the like. In an embodiment of the present application, the cleaning equipment may have an autonomous cleaning function, capable of automatically moving around the room to clean the surface of the room. Therefore, the cleaning equipment may be an automatic cleaning device, or may be referred to as an automatic cleaning robot.

[0065] Cleaning equipment uses cleaning fluid or cleaning foam, which is sprayed onto the ground through a nozzle to clean the floor. These cleaning fluids or cleaning foam are formed into a cleaning fluid, which is then output to the nozzle for ejection.

[0066] In some cases, liquid or foam may drip or remain in the nozzle.

[0067] For example, when the cleaning liquid is sucked out from the cleaning liquid tank to form a cleaning fluid and then pumped to the nozzle, when the cleaning liquid is stopped from being sucked out of the cleaning liquid tank, residual cleaning liquid will still slowly flow out of the pipeline and the nozzle, and liquid will drip from the nozzle.

[0068] Or for example, the cleaning liquid is sucked out from the cleaning liquid tank, formed into cleaning foam through bubbling treatment, and then pumped to the nozzle. If the foam is dense, the foam will adhere to the pipe or nozzle. When the cleaning liquid is stopped from being sucked from the cleaning liquid tank, foam will easily drip and remain in the nozzle. If the foam is very thin, the foam effect is poor, resulting in a general cleaning effect. At the same time, there will be residual cleaning foam or cleaning liquid in the pipe and nozzle that slowly flows out, causing liquid to drip from the nozzle, affecting the cleaning experience and usage perception.

[0069] The present application proposes a solution to improve the problem of liquid or foam dripping and residue easily occurring on the nozzle of the above-mentioned cleaning equipment.

[0070] In order to illustrate the technical solution described in this application, specific embodiments are provided below.

[0071] In the embodiments of the present application, the component structure of the cleaning equipment is first described.

[0072] The cleaning device includes a cleaning fluid generating component, which is connected to the nozzle via a fluid supply pipeline, and the fluid supply pipeline is connected to a first liquid pump.

[0073] The fluid supply pipeline is used to deliver the cleaning fluid to the nozzle.

[0074] The first liquid pump is used to reversely pump the fluid supply pipeline to achieve back-drawing of the liquid in the fluid supply pipeline.

[0075] In some embodiments, the first liquid pump is connected to the fluid supply pipeline near the nozzle. Optionally, the first liquid pump is connected to the fluid supply pipeline through a three-way pipe fitting and is connected to the nozzle through the three-way pipe fitting.

[0076] In some embodiments, the first liquid pump is connected to a clean water tank, a sewage tank, or the ground.

[0077] To clean the floor, the cleaning equipment is equipped with a clean water tank and a wastewater tank. The clean water tank stores clean water, which is pumped out by a liquid pump for floor cleaning. The wastewater tank recovers the dirty mixed liquid after floor cleaning.

[0078] When the first liquid pump is connected to the clean water tank, the existing liquid pump for pumping clean water for floor cleaning can be reused, thereby improving equipment performance and saving manufacturing costs.

[0079] When the first liquid pump is connected to a sewage tank, the existing sewage tank can be directly used to recover the sucked-back cleaning fluid, thereby meeting functional requirements and saving manufacturing costs.

[0080] When the first liquid pump is connected to the ground, the recovered cleaning fluid is directly sprinkled on the ground, which reduces the dripping of the nozzle and does not waste cleaning materials, thus being environmentally friendly and economical.

[0081] The first liquid pump may be a liquid pump already installed in the fluid supply pipeline. In the embodiment of the present application, it is necessary to assign a new function to the first liquid pump to achieve reuse of the first liquid pump for implementing the reverse suction control in the subsequent method. Alternatively, the first liquid pump is a newly added liquid pump in the fluid supply pipeline.

[0082] The generating component is used to generate a cleaning fluid, which can be a cleaning liquid (including clean water), a mixture of a cleaning liquid and air, or cleaning foam.

[0083] Cleaning equipment uses cleaning fluid to clean the surface to be cleaned. For different cleaning fluids, the components configured in the cleaning equipment are different.

[0084] In one example, combining Figure 1 As shown, the generating components in the cleaning equipment include an air pump and a second liquid pump connected to the cleaning liquid tank; the air pump and the second liquid pump are connected to the gas-liquid mixing tank, and the gas-liquid mixing tank is connected to the nozzle through a fluid supply pipeline.

[0085] The cleaning liquid tank is used to contain cleaning liquid.

[0086] The second liquid pump is used to suck out the cleaning liquid in the cleaning liquid tank and pump it into the gas-liquid mixing tank.

[0087] The air pump is used to pump gas to the gas-liquid mixing chamber, so that the gas and cleaning liquid are mixed in the gas-liquid mixing chamber to form a cleaning fluid. It can also be used as an assisting component for the cleaning fluid to flow toward the nozzle, which can assist in the ejection of the cleaning fluid. It is suitable for cleaning equipment that contains an air pump to assist in the spraying of cleaning fluid.

[0088] In some implementations, the second liquid pump and the air pump are connected to the gas-liquid mixing chamber via a three-way pipe, and the air pump generates positive pressure to mix the gas and the cleaning liquid. The generating component generates a mixture of the cleaning liquid and air to form a cleaning fluid.

[0089] In another example, combining Figure 2 As shown, the generating component includes an air pump and a second liquid pump connected to the cleaning liquid tank; the air pump and the second liquid pump are connected to the gas-liquid mixing tank, the gas-liquid mixing tank is connected to the bubbler, and the bubbler is connected to the nozzle through a fluid supply pipeline.

[0090] The bubbler is used to bubble the mixture of cleaning liquid and air to form a foamy cleaning fluid.

[0091] The gas-liquid mixing chamber and the bubbler can be connected via a docking joint.

[0092] The difference between this example and the previous example is that a bubbler is connected after the gas-liquid mixing chamber in the generation component, and the bubbler is connected to the nozzle through a fluid supply pipeline. The generated cleaning fluid is cleaning foam, which can be used in cleaning equipment that sprays foam from the nozzle.

[0093] Optionally, in the above two examples, a one-way valve is provided between the air pump and the gas-liquid mixing chamber.

[0094] Alternatively, the one-way valve can be installed in the three-way pipe between the air pump and the gas-liquid mixing chamber, or at the output end of the air pump facing the gas-liquid mixing chamber. Alternatively, the inside of the air pump can be provided with additional protection to reduce water vapor corrosion.

[0095] The setting of the one-way valve allows the gas pumped by the air pump to go only to the gas-liquid mixing chamber, which can prevent the air pump from being directly connected to the liquid line, prevent the water vapor mixture from flowing back into the air pump, reduce water vapor reflux, and avoid water vapor entering the air pump and causing corrosion.

[0096] Based on the above-mentioned different component structures, embodiments of the present application provide some control methods for cleanable equipment.

[0097] See also Figure 3 , Figure 3 This is a flow chart of a control method for a cleaning device provided in an embodiment of the present application.

[0098] In some cases, when the cleaning device includes a cleaning fluid generating component, the generating component is connected to the nozzle through a fluid supply pipeline, and the fluid supply pipeline is connected to a first liquid pump, such as Figure 3 As shown, the control method of the cleaning device includes the following steps:

[0099] Step 301: Control the generating component to generate a cleaning fluid, so as to provide the cleaning fluid to the nozzle through the fluid supply pipeline.

[0100] The component composition of the generation component can be found in the descriptions of the two aforementioned examples.

[0101] Correspondingly, the above step 301 has implementation processes corresponding to the above two examples respectively.

[0102] In an optional implementation, when the generation component includes an air pump and a second liquid pump connected to the cleaning liquid tank; the air pump and the second liquid pump are connected to the gas-liquid mixing tank, and the gas-liquid mixing tank is connected to the nozzle via a fluid supply pipeline, step 301, controlling the generation component to generate the cleaning fluid to provide the cleaning fluid to the nozzle via the fluid supply pipeline, includes:

[0103] The air pump and the second liquid pump are started to form a gas-liquid mixture in the gas-liquid mixing chamber and then supply the gas-liquid mixture to the nozzle through the fluid supply pipeline.

[0104] During this process, the generating component generates a mixture of cleaning liquid and air to form a cleaning fluid, which is suitable for some application scenarios that require cleaning with a mixture of cleaning liquid and air to meet functional requirements.

[0105] In an optional implementation, when the generation component includes an air pump, a second liquid pump connected to the cleaning liquid tank; the air pump and the second liquid pump are connected to the gas-liquid mixing tank, the gas-liquid mixing tank is connected to the bubbler, and the bubbler is connected to the nozzle via a fluid supply line, step 301, controlling the generation component to generate the cleaning fluid to provide the cleaning fluid to the nozzle via the fluid supply line, includes:

[0106] The air pump and the second liquid pump are started to form a gas-liquid mixture in the gas-liquid mixing chamber and output it to the bubbler to generate cleaning foam, and the cleaning foam is provided to the nozzle through the fluid supply pipeline.

[0107] During this process, the generating component generates cleaning foam to form a cleaning fluid, which is suitable for some application scenarios that require cleaning with cleaning foam to meet functional requirements.

[0108] Step 302 : Control the generation component to stop generating the cleaning fluid, and control the first liquid pump to reversely pump the fluid supply pipeline.

[0109] During the process of the generation component generating cleaning fluid and supplying the cleaning fluid to the nozzle through the fluid supply pipeline, the pressure in the fluid supply pipeline is greater than the pressure outside the nozzle. After the control generation component stops generating cleaning fluid, the pressure in the fluid supply pipeline still exists and is still greater than the pressure outside the nozzle. There is cleaning fluid that has not been discharged remaining in the fluid supply pipeline, and the cleaning fluid will flow out.

[0110] In order to ensure that the residual cleaning fluid in the fluid supply pipeline can be quickly discharged and reduce dripping or residue at the nozzle, in an embodiment of the present application, when the control generation component stops generating cleaning fluid, the first liquid pump connected to the fluid supply pipeline is controlled to reverse and reversely pump the fluid supply pipeline.

[0111] This can accelerate the flow of cleaning fluid remaining in the fluid supply line that has not been discharged toward the nozzle, accelerate the emptying of the cleaning fluid, and reversely suck the flowing cleaning fluid and the cleaning fluid remaining at the nozzle out of the fluid supply line, reducing the cleaning fluid flowing to the nozzle, and avoiding the cleaning fluid attached to the fluid supply line or nozzle after the generation of cleaning fluid stops being sprayed out of the nozzle, resulting in dripping and residue at the nozzle, thereby improving the cleaning experience and usage perception.

[0112] In some usage processes, through the above-mentioned control processing, the cleaning fluid does not have to be limited to sparse foam. High-foam cleaning fluid can be used. Under the premise of ensuring dense foam, it will not cause dripping from the nozzle and foam residue.

[0113] In view of the different component compositions of the generation component in the two aforementioned examples, the above step 302 has a step implementation process that is adapted to both examples.

[0114] In an optional implementation process, step 302 controls the generation component to stop generating the cleaning fluid and controls the first liquid pump to reversely pump the fluid supply line, including:

[0115] Turn off the second liquid pump and keep the air pump on;

[0116] When the second liquid pump is turned off, the first liquid pump is started and controlled to reverse, so as to reversely pump the fluid supply line.

[0117] This process is achieved by directly shutting down the second liquid pump and stopping the cleaning liquid from being pumped out from the cleaning liquid tank when the generation component is controlled to stop generating the cleaning fluid.

[0118] When shutting down the second liquid pump, the air pump needs to remain on. Under this premise, the first liquid pump is started and reversed to pump the fluid supply line in the opposite direction. The second liquid pump stops operating first, and the air pump and the first liquid pump continue to operate. Optionally, after a set time (e.g., 5 seconds) is reached, the air pump and the first liquid pump are controlled to shut down and stop operating.

[0119] In this way, by delaying the closing of the air pump, the cleaning fluid remaining in the fluid supply pipeline that has not been discharged is blown toward the nozzle, and the reversed first liquid pump pumps the cleaning fluid remaining in the fluid supply pipeline that has not been discharged toward the nozzle. The delayed closing of the air pump cooperates with the reversed first liquid pump to accelerate the pressure balance in the pipe, more thoroughly remove the residual cleaning fluid, shorten the cleaning fluid removal time, and accelerate the emptying of the cleaning fluid. At the same time, it is convenient for the first liquid pump to better back-pump the flowing cleaning fluid and the cleaning fluid remaining at the nozzle, so that the residual fluid in the pipeline will not remain and drip from the nozzle.

[0120] In an optional implementation process, step 302 controls the generation component to stop generating the cleaning fluid and controls the first liquid pump to reversely pump the fluid supply line, including:

[0121] Control the second liquid pump to reverse direction and keep the air pump on;

[0122] When the second liquid pump rotates in reverse, the first liquid pump is started and controlled to rotate in reverse, so as to reversely pump the fluid supply line.

[0123] This process is achieved by controlling the second liquid pump to reverse when the generation component stops generating the cleaning fluid. This stops pumping the cleaning fluid out of the cleaning fluid tank and simultaneously reversely pumps the cleaning fluid remaining in the fluid supply line back into the cleaning fluid tank.

[0124] The coverage of the second liquid pump's reverse suction operation in the fluid supply pipeline is determined by the magnitude of the negative pressure generated by the second liquid pump, and the two are specifically positively correlated. In one example, the second liquid pump can reversely suction clean fluid remaining in the pipeline between the second liquid pump and the gas-liquid mixing chamber, reversely suction clean fluid remaining in the gas-liquid mixing chamber, reversely suction clean fluid remaining in the pipeline between the gas-liquid mixing chamber and the bubbler, and so on.

[0125] While the second liquid pump is being controlled to reverse, the air pump remains on. Under this premise, the first liquid pump is started and reversed to pump the fluid supply line in the opposite direction. The second liquid pump first stops pumping cleaning fluid from the cleaning fluid reservoir, and the air pump and the first liquid pump continue to operate. Optionally, after a set time (e.g., 5 seconds) has expired, the second liquid pump, the air pump, and the first liquid pump are controlled to shut down and cease operation.

[0126] In this way, by reversing the second liquid pump, the cleaning fluid remaining in the suction coverage area of ​​the second liquid pump is reversely sucked, so that this part of the residual cleaning fluid can be cleared, and the existing second liquid pump can be reused, which improves equipment performance and saves manufacturing costs. At the same time, the air pump is delayed to shut down, and the cleaning fluid remaining in the fluid supply pipeline that has not been discharged is continuously blown toward the nozzle. Combined with the reversal of the first liquid pump, the cleaning fluid remaining in the fluid supply pipeline that has not been discharged is superimposed and pumped toward the nozzle. The three work together to accelerate the balance of pressure in the pipe, further thoroughly remove the residual cleaning fluid, shorten the cleaning fluid cleaning time, and accelerate the emptying of the cleaning fluid, so that the first liquid pump can better reverse the flowing cleaning fluid and the cleaning fluid remaining at the nozzle, so that the residual fluid in the pipeline will not remain and drip from the nozzle.
