[0033] Compared with the prior art, the embodiments of the present application have the following beneficial effects:

[0034] The pipeline of the cleaning equipment of the embodiment of the present application is provided with a control valve, which is located between the air pump and the second outlet of the pipeline. The air pump can be connected to the second outlet by opening the control valve, so that the gas of the air pump can be discharged from the second outlet. At the same time, the controller of the embodiment of the present application is electrically connected to the control valve, the air pump and the foam pump. In response to triggering the foam spraying mode, it can control the air pump to start and the control valve to open. At this time, the air pump is connected to the second outlet and the gas in the pipeline can be discharged from the second outlet. Then, after the first predetermined time period of the control valve opening, the control valve is controlled to close and the foam pump is started. The air pump is allowed to run for a period of time first, and then the control valve is controlled to close. At this time, the gas of the air pump is not discharged from the second outlet, and the foam pump is started, so that the air pump can spray the foam generated by the foam generating assembly from the nozzle connected to the first outlet.

[0035] Since it takes a certain amount of time for the air pump to start and run at full voltage, the embodiment of the present application first starts the control valve to open when the foam spraying mode is triggered, connects the air pump to the second outlet, and delays the start of the foam pump. After the control valve is opened for a first predetermined period of time, the control valve is closed and the foam pump is started. At this time, the operating state of the air pump is relatively stable and can provide sufficient pressure in the pipeline, thereby avoiding the problem that the foam sprayed under low pressure state has low spray force and is easy to remain near the nozzle. That is, the embodiment of the present application can improve the problem of residual foam spraying, extend the service life of the cleaning equipment, and facilitate user use.

[0036] It can be understood that the beneficial effects of the second to fifth aspects mentioned above can be found in the relevant description of the first aspect mentioned above, and will not be repeated here. BRIEF DESCRIPTION OF THE DRAWINGS

[0060] The pipeline 11 includes a first outlet 111 and a second outlet 112. The foam generating assembly 12 includes a nozzle 121 connected to the first outlet 111, and an air pump 122 and a foam pump 123 connected to the pipeline 11. The control valve 13 is provided in the pipeline 11 and is located between the air pump 122 and the second outlet 112.

[0061] The second outlet 112 may be connected to other structures or equipment or the atmosphere.

[0062] See also Figure 2 As shown, the embodiment of the present application provides a control connection block diagram of a cleaning device 1. Figure 2 As shown, the cleaning device 1 further includes a controller 14. The controller 14 is electrically connected to the control valve 13, the air pump 122 and the foam pump 123.

[0063] The controller 14 is configured to control the air pump 122 to start and the control valve 13 to open in response to triggering the foam spraying mode, so as to discharge the gas in the pipeline 11 from the second outlet 112; after the control valve 13 is opened for a first predetermined period of time, the control valve 13 is closed and the foam pump 123 is started to spray the foam generated by the foam generating assembly 12 from the nozzle 121.

[0064] Optionally, the control valve 13 is in a normally closed state, and the opening of the control valve 13 is controlled by the controller 14 .

[0065] See also Figure 3 As shown, the embodiment of the present application provides another schematic diagram of the pipeline connection of the cleaning device 1. Figure 3 As shown, the foam generating assembly 12 further includes a bubbler 124 , a solution tank 125 and a cleaning liquid pump 126 .

[0066] The solution tank 125 is used to store cleaning liquid. The bubbler 124 is connected to the nozzle 121 via the foam section of the pipeline 11. The bubbler 124 can also be connected to the foam pump 123 via the docking port and the first connecting valve. The solution tank 125, the cleaning liquid pump 126, and the foam pump 123 can all be connected via the second connecting valve. The cleaning liquid pump 126 can output the cleaning liquid to the foam pump 123.

[0067] Optionally, a third communication valve is further connected between the air pump 122 and the control valve 13. The third communication valve is connected to the first communication valve via a connecting section of the pipeline 11.

[0068] Wherein, the first connecting valve, the second connecting valve and the third connecting valve are all three-way valves.

[0069] Optionally, the cleaning device 1 further includes a clean water tank for containing clean water, a clean water pump, a water replenishing bar and a roller brush.

[0070] Among them, the cleaning liquid pump 126 is connected to the clean water tank and the clean water pump through a fourth connecting valve. The clean water pump is connected to the water replenishment bar through the water supply section of the pipeline 11, and the water replenishment bar is connected to the roller brush. The clean water pump can transport clean water to the water replenishment bar through the water supply section, and evenly send the water to the roller brush through the water replenishment bar to scrub the floor.

[0071] Optionally, the cleaning device 1 may be a floor scrubber having the function of spraying foam onto the floor.

[0072] The pipeline 11 of the cleaning device 1 of the embodiment of the present application is provided with a control valve 13, which is located between the air pump 122 and the second outlet 112 of the pipeline 11. The control valve 13 can be opened to connect the air pump 122 with the second outlet 112, so that the gas in the air pump 122 can be discharged from the second outlet 112. At the same time, the controller 14 of the embodiment of the present application is electrically connected to the control valve 13, the air pump 122, and the foam pump 123. In response to triggering the foam spraying mode, the controller 14 can control the start of the air pump 122 and the opening of the control valve 13. At this time, the air pump 122 is connected to the second outlet 112, and the gas in the pipeline 11 can be discharged from the second outlet 112. Then, after the control valve 13 is opened for the first predetermined period of time, the control valve 13 is controlled to close and the foam pump 123 is started. The air pump 122 is allowed to run for a period of time, and then the control valve 13 is controlled to close. The gas of the air pump 122 is not discharged from the second outlet 112, and the foam pump 123 is started, so that the air pump 122 can spray the foam generated by the foam generating component 12 from the nozzle 121 connected to the first outlet 111.

[0073] Since it takes a certain amount of time for the air pump 122 to start and run at full voltage, the embodiment of the present application first starts the control valve 13 to open when the foam spraying mode is triggered, connects the air pump 122 with the second outlet 112, and delays the start of the foam pump 123. After the control valve 13 is opened for a first predetermined period of time, the control valve 13 is closed and the foam pump 123 is started. At this time, the operating state of the air pump 122 is relatively stable, and sufficient pressure can be provided in the pipeline, thereby avoiding the problem that the foam sprayed under low pressure state has low spray force and is easy to remain near the nozzle 121. That is, the embodiment of the present application can improve the problem of residual foam spraying, extend the service life of the cleaning equipment 1, and facilitate user use.

[0074] In the embodiment of the present application, a control valve 13 is added to the pipeline 11 , and the problem of residual foam is improved through the control logic of the controller 14 , thereby reducing or avoiding the residual foam in the nozzle 121 .

[0075] In some embodiments, the first predetermined time period is not less than the time required for the air pump 122 to start up and reach a normal operating state; and / or, the first predetermined time period is 400 milliseconds to 600 milliseconds.

[0076] Optionally, the first predetermined duration may be 400 milliseconds, 500 milliseconds, 600 milliseconds, etc.

[0077] As an example, the present embodiment provides an implementation method: When the foam spray mode is triggered, the air pump 122 starts immediately, and the control valve 13 opens immediately. After 500ms, the control valve 13 closes, and the foam pump 123 starts after a delay of 500ms. Through the control logic of the present embodiment, when the control valve 13 closes (i.e., after 500ms), the air pump 122 in the pipeline 11 is in normal operation, preventing the foam sprayed under low pressure from being weak and remaining near the nozzle 121.

[0078] In some embodiments, the control valve 13 is a solenoid valve; and / or the second outlet 112 is connected to the atmosphere.

[0079] The control valve 13 of the embodiment of the present application is a solenoid valve, which can be directly controlled to start, open and close by an electrical signal sent by the controller 14, and has a fast and sensitive response.

[0080] The second outlet 112 of the embodiment of the present application is connected to the atmosphere, and the gas of the air pump 122 can be directly discharged from the cleaning device 11 at the initial start-up of the air pump 122, and can be directly blown to the ground.

[0081] In some embodiments, the controller 14 is also configured to stop the foam spraying mode in response to a trigger, control the foam pump 123 to stop, and control the air pump 122 to keep working to spray the foam in the pipeline 11 out of the nozzle 121; after the foam pump 123 stops for a second predetermined period of time, the control valve 13 is controlled to open to discharge the gas in the pipeline 11 from the second outlet 112; after the control valve 13 is opened for a third predetermined period of time, the control valve 13 is controlled to close, and the air pump 122 is controlled to stop between the opening and closing of the control valve 13.

[0082] In some embodiments, the second predetermined time length is 1 second to 2 seconds; and / or the third predetermined time length is 1 second to 2 seconds.

[0083] Optionally, the second predetermined time length and the third predetermined time length can be the same or different. The second predetermined time length can be selected from 1 second, 1.5 seconds, 2 seconds, etc., and the third predetermined time length can be selected from 1 second, 1.5 seconds, 2 seconds, etc.

[0084] In some embodiments, the controller 14 is further configured to control the control valve 13 to close after the air pump 122 stops for a fourth predetermined time period; wherein the fourth predetermined time period is not less than the time required for the pressure in the pipeline 11 to drop to atmospheric pressure after the air pump 122 stops.

[0085] Optionally, the fourth predetermined time length is 0.5 seconds. The specific value of the fourth predetermined time length can be determined based on data and experience in actual work applications.

[0086] Since the main reason for the residual foam is that the residual pressure in the pipeline 11 is released from the nozzle 121, bringing out the residual foam at the nozzle of the nozzle 121. In the embodiment of the present application, in response to the triggering to stop the foam spraying mode, the foam pump 123 can be controlled to stop, and after the foam pump 123 stops for a second predetermined time, the control valve 13 is controlled to open for a third predetermined time and then close. The air pump 122 is controlled to stop between the opening and closing of the control valve 13, so that the pressure in the pipeline 11 can be released. At the same time, the air pump 122 is turned off. After the pressure in the pipeline 11 leaks from the control valve 13 to the standard atmospheric pressure, the control valve 13 is closed. In this way, there will be no foam remaining at the nozzle of the nozzle 121 due to the pressure spraying.

[0087] As an example, the embodiment of the present application provides an implementation method: after the foam spraying mode is triggered to stop, the foam pump 123 stops immediately; after 1.5 seconds, the control valve 13 opens and closes after 1.5 seconds; the air pump 122 continues to work for 2.5 seconds and then closes. Through the control logic of the embodiment of the present application, the air pump 122 sprays most of the foam in the pipeline 11 in the first 1.5 seconds. After the control valve 13 is opened, the pressure in the pipeline 11 can be released. Then, the air pump 122 is turned off, and after the pressure in the pipeline 11 leaks to the standard atmospheric pressure through the control valve 13, the control valve 13 is closed. In this way, there will be no foam remaining at the nozzle of the nozzle 121 due to pressure spraying.

[0088] In some embodiments, the control valve 13 is provided with an elastic seal; the elastic seal is used to drive the control valve 13 to open when the pressure in the pipeline 11 is greater than the elastic force threshold.

[0089] Alternatively, control valve 13 can be a solenoid valve. In its normally closed state, the solenoid valve can be sealed by an elastic seal, thus also serving as pressure protection for pipeline 11. When pipeline 11 experiences high pressure due to an abnormal situation such as a blockage, the pressure in pipeline 11 exceeds the pressure threshold of the solenoid valve, and the pressure can leak out of the solenoid valve, preventing a pipe burst.

[0090] See also Figure 4 As shown, the embodiment of the present application provides another control connection block diagram of the cleaning device 111. Figure 4 As shown, the cleaning device 111 further includes a pressure sensor 15 provided in the pipeline 11 .

[0091] The controller 14 is further configured to control the control valve 13 to open when the pressure sensor 15 detects that the pressure in the pipeline 11 is greater than a preset pressure.

[0092] The embodiment of the present application can detect the pressure in the pipeline 11 in real time through the pressure sensor 15. When the pressure in the pipeline 11 is greater than the preset pressure, the controller 14 can control the control valve 13 to open, thereby achieving pressure protection for the pipeline 11.

[0093] Based on the above technical solution, the cleaning device 111 of the embodiment of the present application can improve the residual foam at the nozzle of the nozzle 121. At the same time, the cleaning device 111 of the embodiment of the present application can also take into account the pressure protection of the pipeline 11 by setting an elastic seal or a pressure sensor 15.

[0094] See also Figure 5 As shown, an embodiment of the present application provides a flow chart of a control method for a cleaning device 1. The control method of the embodiment of the present application is applied to the cleaning device 111 of the embodiment of the present application. Among them, the cleaning device 1 includes: a pipeline 11, a foam generating component 12, a control valve 13 and a controller 14. The pipeline 11 includes a first outlet 111 and a second outlet 112. The foam generating component 12 includes a nozzle 121 connected to the first outlet 111, and an air pump 122 and a foam pump 123 connected to the pipeline 11. The control valve 13 is provided in the pipeline 11 and is located between the air pump 122 and the second outlet 112. The controller 14 is electrically connected to the control valve 13, the air pump 122 and the foam pump 123. As shown Figure 5 As shown, the control method of the cleaning device 1 according to the embodiment of the present application includes: step S501 to step S502.

[0095] S501 , in response to triggering the foam spraying mode, controlling the air pump 122 to start and the control valve 13 to open, so as to discharge the gas in the pipeline 11 from the second outlet 112 .

[0096] S502 , after the control valve 13 is opened for a first predetermined time, the control valve 13 is controlled to close and the foam pump 123 is started to spray the foam generated by the foam generating assembly 12 out of the spray head 121 .

[0097] The control method of the cleaning device 1 according to the embodiment of the present application may be executed by the controller 14 .

[0098] The control method of the cleaning device 1 of the embodiment of the present application can control the air pump 122 to start and the control valve 13 to open in response to triggering the foam spraying mode. At this time, the air pump 122 is connected to the second outlet 112, and the gas in the pipeline 11 can be discharged from the second outlet 112. Then, after the control valve 13 is opened for a first predetermined period of time, the control valve 13 is controlled to close and the foam pump 123 is started. The air pump 122 is allowed to run for a period of time, and then the control valve 13 is controlled to close. The gas of the air pump 122 is not discharged from the second outlet 112, and the foam pump 123 is started, so that the air pump 122 can spray the foam generated by the foam generating assembly 12 from the nozzle 121 connected to the first outlet 111.

[0099] Since it takes a certain amount of time for the air pump 122 to start and run at full voltage, the embodiment of the present application first starts the control valve 13 to open when the foam spraying mode is triggered, connects the air pump 122 with the second outlet 112, and delays the start of the foam pump 123. After the control valve 13 is opened for a first predetermined period of time, the control valve 13 is closed and the foam pump 123 is started. At this time, the operating state of the air pump 122 is relatively stable, and sufficient pressure can be provided in the pipeline, thereby avoiding the problem that the foam sprayed under low pressure state has low spray force and is easy to remain near the nozzle 121. That is, the embodiment of the present application can improve the problem of residual foam spraying, extend the service life of the cleaning equipment 1, and facilitate user use.

[0100] In some embodiments, the control method of the cleaning device 1 of the embodiment of the present application further includes:

[0101] In response to the triggering of stopping the foam spraying mode, the foam pump 123 is controlled to stop, and the air pump 122 is controlled to keep working, so as to spray the foam in the pipeline 11 from the spray head 121;

[0102] After the foam pump 123 stops for a second predetermined period of time, the control valve 13 is controlled to open to discharge the gas in the pipeline 11 from the second outlet 112;

[0103] After the control valve 13 is opened for a third predetermined time period, the control valve 13 is controlled to close, and the control air pump 122 is stopped between the opening and closing of the control valve 13 .

[0104] In some embodiments, controlling the air pump 122 to stop between opening and closing the control valve 13 includes:

[0105] After the air pump 122 is stopped for a fourth predetermined time, the control valve 13 is controlled to close; wherein the fourth predetermined time is not less than the time required for the pressure in the pipeline 11 to drop to atmospheric pressure after the air pump 122 stops.

[0106] The control method of the embodiment of the present application can respond to the trigger to stop the foam spraying mode, control the foam pump 123 to stop, and after the second predetermined time after the foam pump 123 stops, control the control valve 13 to open for a third predetermined time and then close, and control the air pump 122 to stop between the opening and closing of the control valve 13, so as to release the pressure in the pipeline 11 and shut down the air pump 122 at the same time. After the pressure in the pipeline 11 leaks from the control valve 13 to the standard atmospheric pressure, the control valve 13 is closed, so that there will be no foam remaining at the nozzle of the nozzle 121 due to the pressure spraying.

[0107] In some embodiments, the control method of the cleaning device 1 further includes: when the pressure detected by the pressure sensor 15 provided in the pipeline 11 is greater than a preset pressure, controlling the control valve 13 to open.

[0108] The control method of the cleaning equipment 1 in the embodiment of the present application can detect the pressure in the pipeline 11 in real time through the pressure sensor 15. When the pressure in the pipeline 11 is greater than the preset pressure, the controller 14 can control the control valve 13 to open, thereby realizing pressure protection of the pipeline 11.

[0109] See also Figure 6 As shown, an embodiment of the present application provides a structural schematic diagram of a control device 60 of a cleaning device. The control device 60 of the cleaning device of the embodiment of the present application is applied to the cleaning device 111 of the embodiment of the present application. Among them, the cleaning device 1 includes: a pipeline 11, a foam generating component 12, a control valve 13 and a controller 14. The pipeline 11 includes a first outlet 111 and a second outlet 112. The foam generating component 12 includes a nozzle 121 connected to the first outlet 111, and an air pump 122 and a foam pump 123 connected to the pipeline 11. The control valve 13 is provided in the pipeline 11 and is located between the air pump 122 and the second outlet 112. The controller 14 is electrically connected to the control valve 13, the air pump 122 and the foam pump 123. As shown Figure 6 As shown, the control device 60 of the cleaning equipment includes: a first control module 601 and a second control module 602 .

[0110] The first control module 601 is configured to control the air pump 122 to start and the valve 13 to open in response to triggering the foam spraying mode, so as to discharge the gas in the pipeline 11 from the second outlet 112 .

[0111] The second control module 602 is configured to control the control valve 13 to close and the foam pump 123 to start after the control valve 13 is opened for a first predetermined period of time, so as to spray the foam generated by the foam generating assembly 12 out of the spray head 121 .

[0112] The control device 60 of the cleaning device of the embodiment of the present application can control the air pump 122 to start and the control valve 13 to open in response to triggering the foam spraying mode. At this time, the air pump 122 is connected to the second outlet 112, and the gas in the pipeline 11 can be discharged from the second outlet 112. Then, after the control valve 13 is opened for a first predetermined period of time, the control valve 13 is controlled to close and the foam pump 123 is started. After the air pump 122 is allowed to run for a period of time, the control valve 13 is controlled to close, and the gas in the air pump 122 is not discharged from the second outlet 112. The foam pump 123 is started, so that the air pump 122 can spray the foam generated by the foam generating assembly 12 from the nozzle 121 connected to the first outlet 111.

[0113] Since it takes a certain amount of time for the air pump 122 to start and run at full voltage, the embodiment of the present application first starts the control valve 13 to open when the foam spraying mode is triggered, connects the air pump 122 with the second outlet 112, and delays the start of the foam pump 123. After the control valve 13 is opened for a first predetermined period of time, the control valve 13 is closed and the foam pump 123 is started. At this time, the operating state of the air pump 122 is relatively stable, and sufficient pressure can be provided in the pipeline, thereby avoiding the problem that the foam sprayed under low pressure state has low spray force and is easy to remain near the nozzle 121. That is, the embodiment of the present application can improve the problem of residual foam spraying, extend the service life of the cleaning equipment 1, and facilitate user use.

[0114] Optionally, the control device 60 of the cleaning device in the embodiment of the present application further includes: a third control module, a fourth control module and a fifth control module.

[0115] The third control module is used for controlling the foam pump 123 to stop in response to the triggering to stop the foam spraying mode, and controlling the air pump 122 to keep working, so as to spray the foam in the pipeline 11 out of the spray head 121 .

[0116] The fourth control module is configured to control the control valve 13 to open after the foam pump 123 stops for a second predetermined period of time, so as to discharge the gas in the pipeline 11 from the second outlet 112 .

[0117] The fifth control module is configured to control the control valve 13 to close after the control valve 13 is opened for a third predetermined time period, and to control the air pump 122 to stop between the opening and closing of the control valve 13 .

[0118] Optionally, the fifth control module is specifically used to control the control valve 13 to close after the air pump 122 stops for a fourth predetermined time; wherein the fourth predetermined time is not less than the time required for the pressure in the pipeline 11 to drop to atmospheric pressure after the air pump 122 stops.

[0119] The control device 60 of the cleaning equipment of the embodiment of the present application can respond to the trigger to stop the foam spraying mode, control the foam pump 123 to stop, and after the second predetermined time after the foam pump 123 stops, control the control valve 13 to open for a third predetermined time and then close it, and control the air pump 122 to stop between the opening and closing of the control valve 13, so as to release the pressure in the pipeline 11 and shut down the air pump 122 at the same time. After the pressure in the pipeline 11 leaks from the control valve 13 to the standard atmospheric pressure, the control valve 13 is closed, so that there will be no foam remaining at the nozzle of the nozzle head 121 due to the pressure spraying.

[0120] Optionally, the control device 60 of the cleaning equipment further includes a sixth control module, which is configured to control the control valve 13 to open when the pressure detected by the pressure sensor 15 provided in the pipeline 11 is greater than a preset pressure.

[0121] The control device 60 of the cleaning equipment in the embodiment of the present application can detect the pressure in the pipeline 11 in real time through the pressure sensor 15. When the pressure in the pipeline 11 is greater than the preset pressure, the control valve 13 is controlled to open to achieve pressure protection of the pipeline 11.
