Description

Technical Field

[0001] This application relates to the technical field of cleaning equipment, and more particularly to a cleaning device and its control method, control device, and storage medium. Background Technology

[0002] Currently, cleaning equipment generally has the function of spraying foam onto the surface to be cleaned in order to improve the cleaning effect.

[0003] However, foam residue often remains at the nozzle after the cleaning equipment finishes spraying, affecting the quality or appearance of the nozzle and thus shortening the service life of the cleaning equipment. Moreover, it often requires manual cleaning, which causes inconvenience to users. Summary of the Invention

[0004] In view of this, embodiments of this application provide a cleaning device and its control method, control device, and storage medium to solve the problem in the prior art where residual foam at the nozzle of the cleaning device shortens the service life of the cleaning device or causes inconvenience to the user.

[0005] A first aspect of this application provides a cleaning device, comprising:

[0006] Pipeline, including first outlet and second outlet;

[0007] The foam generating assembly includes a nozzle connected to a first outlet, and an air pump and a foam pump both connected to pipelines.

[0008] The control valve is located in the pipeline, between the air pump and the second outlet;

[0009] The controller, electrically connected to the control valve, air pump, and foam pump, is configured to, in response to triggering a foam spraying mode, control the air pump to start and the control valve to open to discharge gas in the pipeline from the second outlet; and, after a first predetermined duration of the control valve being open, control the control valve to close and the foam pump to start to spray foam generated by the foam generating component from the nozzle.

[0010] In one possible implementation, the first predetermined duration is not less than the time required for the air pump to start up and reach normal operating status;

[0011] And / or, the first predetermined duration is 400-600 milliseconds.

[0012] In one possible implementation, the controller is also configured to, in response to triggering a stop foam spraying mode, control the foam pump to stop, control the air pump to remain operational to spray foam from the nozzles within the pipeline; control the control valve to open after a second predetermined time period following the foam pump's stoppage to discharge gas from the second outlet within the pipeline; control the control valve to close after a third predetermined time period following the valve's opening, and control the air pump to stop between the opening and closing of the control valve.

[0013] In one possible implementation, the second predetermined duration is 1 to 2 seconds; and / or, the third predetermined duration is 1 to 2 seconds.

[0014] In one possible implementation, the controller is further configured to close the control valve after a fourth predetermined period of time following the shutdown of the air pump; wherein the fourth predetermined period of time is not less than the time required for the pressure in the pipeline to drop to atmospheric pressure after the air pump stops.

[0015] In one possible implementation, the control valve is a solenoid valve; and / or, the second outlet is connected to the atmosphere.

[0016] In one possible implementation, the control valve is equipped with a resilient seal;

[0017] The elastic seal is used to open the control valve when the pressure in the pipeline exceeds the elasticity threshold.

[0018] In one possible implementation, the cleaning device also includes: a pressure sensor located in the pipeline;

[0019] The controller is also configured to open the control valve when the pressure in the pipeline is detected by the pressure sensor to be greater than a preset pressure.

[0020] A second aspect of this application provides a control method for a cleaning device. The cleaning device includes a pipeline, a foam generating assembly, a control valve, and a controller. The pipeline includes a first outlet and a second outlet. The foam generating assembly includes a nozzle connected to the first outlet, and an air pump and a foam pump both connected to the pipeline. The control valve is located in the pipeline between the air pump and the second outlet. The controller is electrically connected to the control valve, the air pump, and the foam pump. The control method includes:

[0021] In response to triggering the foam spray mode, the control air pump starts and the control valve opens to discharge the gas in the pipeline from the second outlet;

[0022] After a first predetermined period of time after the control valve is opened, the control valve is closed and the foam pump is started to spray the foam generated by the foam generating component from the nozzle.

[0023] In one possible implementation, the control method for the cleaning equipment also includes:

[0024] In response to triggering the stop foam spraying mode, the foam pump is controlled to stop, while the air pump is controlled to continue operating to spray foam from the nozzles within the pipeline;

[0025] After a second predetermined period of time following the stop of the foam pump, the control valve opens to discharge the gas in the pipeline from the second outlet.

[0026] After a third predetermined period of time since the control valve opened, the control valve closes, and the control air pump stops between the opening and closing of the control valve.

[0027] In one possible implementation, the control air pump stops between the opening and closing of the control valve, including:

[0028] After a fourth predetermined time period following the stop of the air pump, the control valve is closed; wherein the fourth predetermined time period is not less than the time required for the pressure in the pipeline to drop to atmospheric pressure after the air pump stops.

[0029] In one possible implementation, the control method for the cleaning equipment also includes:

[0030] When the pressure detected by the pressure sensor installed in the pipeline is greater than the preset pressure, the control valve opens.

[0031] A fourth aspect of this application provides a control device, including a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the computer program to implement the steps of the method of the second aspect.

[0032] A fifth aspect of this application provides a computer-readable storage medium storing a computer program that, when executed by a processor, implements the steps of the method of the second aspect.

[0033] The beneficial effects of the embodiments in this application compared with the prior art are:

[0034] The cleaning equipment of this embodiment has a control valve in its piping system, located between the air pump and the second outlet of the piping. Opening the control valve connects the air pump to the second outlet, allowing gas from the air pump to be discharged from the second outlet. Simultaneously, the controller of this embodiment is electrically connected to the control valve, air pump, and foam pump. In response to triggering a foam spraying mode, it controls the air pump to start and the control valve to open. At this time, the air pump is connected to the second outlet, allowing gas from the piping to be discharged from the second outlet. Then, after a first predetermined period of time after the control valve is open, the control valve is closed and the foam pump is started. This allows the air pump to run for a period before the control valve is closed, preventing gas from being discharged from the second outlet. The foam pump then starts, allowing the air pump to spray foam generated by the foam generating component from the nozzle connected to the first outlet.

[0035] Since it takes a certain amount of time for the air pump to operate at full voltage after startup, this embodiment of the application first starts the control valve to open when the foam spraying mode is triggered, connecting the air pump to the second outlet. The foam pump starts with a delay, and after the control valve has been open for a first predetermined time, the control valve is closed and the foam pump is started. At this time, the air pump operates in a relatively stable state and can provide sufficient pressure to the pipeline, thereby avoiding the problem that the foam sprayed under low pressure has a weak spray force and is easy to remain near the nozzle. That is, this embodiment of the application can improve the problem of foam residue, extend the service life of the cleaning equipment, and facilitate user use.

[0036] It is understood that the beneficial effects of the second to fifth aspects mentioned above can be found in the relevant descriptions in the first aspect mentioned above, and will not be repeated here. Attached Figure Description

[0059] See Figure 1 As shown, this application embodiment provides a schematic diagram of the pipeline connection of a cleaning device 1. Figure 1 As shown, the cleaning equipment 1 includes: a pipeline 11, a foam generating assembly 12, and a control valve 13.

[0060] Pipeline 11 includes a first outlet 111 and a second outlet 112. Foam generating assembly 12 includes a nozzle 121 communicating with the first outlet 111, and an air pump 122 and a foam pump 123 communicating with both pipeline 11. Control valve 13 is located in pipeline 11 and between air pump 122 and the second outlet 112.

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

[0062] See Figure 2 As shown, this application embodiment provides a control connection block diagram for a cleaning device 1. (As indicated...) Figure 2 As shown, the cleaning equipment 1 also 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, in response to triggering the foam spray mode, start the air pump 122 and open the control valve 13 to discharge gas in the pipeline 11 from the second outlet 112; after a first predetermined duration of opening the control valve 13, close the control valve 13 and start the foam pump 123 to spray the foam generated by the foam generating assembly 12 from the nozzle 121.

[0064] Optionally, the control valve 13 is normally closed, and the controller 14 controls the opening of the control valve 13.

[0065] See Figure 3 As shown in the figure, this application provides a schematic diagram of the piping connection of another cleaning device 1. For example... Figure 3 As shown, the foam generating assembly 12 also includes a foamer 124, a solution tank 125, and a cleaning fluid pump 126.

[0066] The solution tank 125 is used to hold the cleaning solution. The aerator 124 is connected to the nozzle 121 through the foam section of the pipeline 11. The aerator 124 can also be connected to the foam pump 123 through the interface and the first connecting valve. The solution tank 125, the cleaning solution pump 126, and the foam pump 123 can all be connected through the second connecting valve. The cleaning solution pump 126 can output the cleaning solution to the foam pump 123.

[0067] Optionally, a third connecting valve is also connected between the air pump 122 and the control valve 13. The third connecting valve and the first connecting valve are connected through a connecting section of the pipeline 11.

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

[0069] Optionally, the cleaning device 1 also includes a clean water tank for holding clean water, a clean water pump, a water replenishment strip, and a roller brush.

[0070] The cleaning liquid pump 126 is connected to both the clean water tank and the clean water pump through a fourth connecting valve. The clean water pump is connected to the water supply section of the water supply strip through the pipeline 11. The water supply strip is connected to the roller brush. The clean water pump can deliver clean water to the water supply strip through the water supply section. The water supply strip then delivers the water evenly to the roller brush to clean the floor.

[0071] Alternatively, the cleaning equipment 1 can be a floor scrubber with the function of spraying foam onto the floor.

[0072] The cleaning device 1 of this embodiment is equipped with a control valve 13 in its pipeline 11. The control valve 13 is located between the air pump 122 and the second outlet 112 of the pipeline 11. By opening the control valve 13, the air pump 122 is connected to the second outlet 112, allowing the gas from the air pump 122 to be discharged from the second outlet 112. Simultaneously, the controller 14 of this embodiment 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, it controls the air pump 122 to start and the control valve 13 to open. At this time, the air pump 122 is connected to the second outlet 112, allowing the gas in the pipeline 11 to be discharged from the second outlet 112. Then, after the control valve 13 has been open for a first predetermined period of time, the control valve 13 is closed and the foam pump 123 is started. This is done by allowing the air pump 122 to run for a period of time before the control valve 13 is closed, so that the gas from the air pump 122 is not discharged from the second outlet 112, and the foam pump 123 is started. Thus, 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 reach full voltage operation from startup, this embodiment of the application first starts the control valve 13 when the foam spraying mode is triggered, connecting the air pump 122 to the second outlet 112. The foam pump 123 starts with a delay. After the control valve 13 has been open for a first predetermined 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 can provide sufficient pressure to the pipeline, thereby avoiding the problem that the foam sprayed under low pressure has a weak spray force and is easy to remain near the nozzle 121. That is, this embodiment of the application can improve the problem of foam residue, extend the service life of the cleaning equipment 1, and facilitate user use.

[0074] In this embodiment, a control valve 13 is added to the pipeline 11, and the control logic of the controller 14 is used to improve the problem of foam residue, thereby reducing or avoiding foam residue in the nozzle 121.

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

[0076] Optionally, the first scheduled duration can be selected as 400 milliseconds, 500 milliseconds, 600 milliseconds, etc.

[0077] As an example, this application embodiment provides an implementation method: after triggering the foam spraying mode, the air pump 122 starts immediately, the control valve 13 opens immediately, the control valve 13 closes after 500ms, and the foam pump 123 starts after a 500ms delay. Through the control logic of this application embodiment, when the control valve 13 is closed (i.e., after 500ms), the air pump 122 in the pipeline 11 is in normal operating condition, avoiding weak foam spraying force under low pressure and residue near the nozzle 121.

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

[0079] In this embodiment, the control valve 13 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 this embodiment is connected to the atmosphere, which can directly discharge the gas from the air pump 122 to the cleaning device 11 at the initial stage of the air pump 122 start-up, and can directly blow it to the ground.

[0081] In some embodiments, the controller 14 is further configured to, in response to triggering a stop foam spraying mode, control the foam pump 123 to stop, control the air pump 122 to continue operating to spray foam from the nozzle 121 within the conduit 11; control the control valve 13 to open after a second predetermined duration following the stopping of the foam pump 123, to discharge gas from the conduit 11 through the second outlet 112; control the control valve 13 to close after a third predetermined duration following the opening of the control valve 13, and control the air pump 122 to stop between the opening and closing of the control valve 13.

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

[0083] Optionally, the second and third pre-set durations can be the same or different. The second pre-set duration can be 1 second, 1.5 seconds, 2 seconds, etc., and the third pre-set duration can be 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 a fourth predetermined period of time after the air pump 122 stops; wherein the fourth predetermined period of 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.

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

[0086] The main reason for foam residue is that the residual pressure in the pipe 11 is released from the nozzle 121, carrying away foam residue at the nozzle 121's nozzle opening. In this embodiment, in response to triggering a foam-stopping mode, the foam pump 123 is controlled to stop. 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, thus relieving the pressure in the pipe 11. Simultaneously, the air pump 122 is shut off, allowing the pressure in the pipe 11 to leak from the control valve 13 to standard atmospheric pressure before closing the control valve 13. This prevents foam residue from being ejected due to pressure at the nozzle 121's nozzle opening.

[0087] As an example, this application embodiment provides an implementation method: after triggering the stop foam spraying mode, the foam pump 123 immediately stops; after 1.5 seconds, the control valve 13 opens, and after another 1.5 seconds, it closes; the air pump 122 continues to operate for 2.5 seconds before shutting down. Through the control logic of this application embodiment, the air pump 122 sprays out most of the foam from the pipeline 11 in the first 1.5 seconds. After opening the control valve 13, the pressure in the pipeline 11 can be relieved. Then, the air pump 122 is shut off, and after the pressure in the pipeline 11 leaks through the control valve 13 to standard atmospheric pressure, the control valve 13 is closed, so that no foam remains 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 open the control valve 13 when the pressure in the pipeline 11 is greater than the elasticity threshold.

[0089] Optionally, control valve 13 can be a solenoid valve. In the 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 significant pressure due to abnormal conditions such as blockage, and the pressure exceeds the pressure threshold of the solenoid valve, the pressure can be released from the solenoid valve, preventing pipeline rupture.

[0090] See Figure 4 As shown in the figure, this application embodiment provides a control connection block diagram of another cleaning device 111. (As shown...) Figure 4 As shown, the cleaning device 111 also includes a pressure sensor 15 disposed on the pipeline 11.

[0091] The controller 14 is also configured to open the control valve 13 when the pressure in the pipeline 11 is detected by the pressure sensor 15 to be greater than a preset pressure.

[0092] In this embodiment, the pressure sensor 15 can detect the pressure in the pipeline 11 in real time. When the pressure in the pipeline 11 is greater than the preset pressure, the controller 14 can open the control valve 13 to achieve pressure protection of the pipeline 11.

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

[0094] See Figure 5 The flowchart shown illustrates a control method for a cleaning device 1 provided in this application embodiment. The control method of this application embodiment is applied to a cleaning device 111. The cleaning device 1 includes: a pipeline 11, a foam generating assembly 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 assembly 12 includes a nozzle 121 communicating with the first outlet 111, and an air pump 122 and a foam pump 123 both communicating with the pipeline 11. The control valve 13 is located in the pipeline 11 and 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. Figure 5 As shown, the control method of the cleaning device 1 in this application embodiment includes steps S501 to S502.

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

[0096] S502. After a first predetermined period of time after the control valve 13 is opened, 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.

[0097] In this embodiment, the control method of the cleaning device 1 can be executed by the controller 14.

[0098] The control method of the cleaning device 1 in this embodiment can respond to triggering the foam spraying mode by controlling the air pump 122 to start and the control valve 13 to open. 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 has been open for a first predetermined period of time, the control valve 13 is closed and the foam pump 123 is started. This means that the air pump 122 runs for a period of time before the control valve 13 is closed, so that the gas from the air pump 122 is not discharged from the second outlet 112, and the foam pump 123 is started. Thus, 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.

[0099] Since it takes a certain amount of time for the air pump 122 to reach full voltage operation from startup, this embodiment of the application first starts the control valve 13 when the foam spraying mode is triggered, connecting the air pump 122 to the second outlet 112. The foam pump 123 starts with a delay. After the control valve 13 has been open for a first predetermined 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 can provide sufficient pressure to the pipeline, thereby avoiding the problem that the foam sprayed under low pressure has a weak spray force and is easy to remain near the nozzle 121. That is, this embodiment of the application can improve the problem of foam residue, extend the service life of the cleaning equipment 1, and facilitate user use.

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

[0101] In response to triggering the stop foam spraying mode, control foam pump 123 to stop, and control air pump 122 to continue working so that foam in pipeline 11 is sprayed out from nozzle 121;

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

[0103] After a third predetermined period of time when the control valve 13 is open, the control valve 13 is closed, and the control air pump 122 stops between the opening and closing of the control valve 13.

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

[0105] After a fourth predetermined time period following the stop of the air pump 122, the control valve 13 is closed; 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.

[0106] The control method of this application embodiment can respond to triggering a stop foam spraying mode, control the foam pump 123 to stop, and after a second predetermined time period after the foam pump 123 stops, control the control valve 13 to open for a third predetermined time period and then close it. Control the air pump 122 to stop between the opening and closing of the control valve 13, which can relieve the pressure in the pipeline 11. At the same time, the air pump 122 is turned off, and the pressure in the pipeline 11 can be leaked from the control valve 13 to the standard atmospheric pressure. Then the control valve 13 is closed, so that no foam will be sprayed out and remain at the nozzle of the nozzle 121 due to pressure.

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

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

[0109] See Figure 6 The diagram shows a schematic of the structure of a control device 60 for a cleaning device according to an embodiment of this application. The control device 60 is applied to a cleaning device 111 according to an embodiment of this application. The cleaning device 1 includes: a pipeline 11, a foam generating assembly 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 assembly 12 includes a nozzle 121 communicating with the first outlet 111, and an air pump 122 and a foam pump 123 both communicating with the pipeline 11. The control valve 13 is located in the pipeline 11 and 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. 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 used to control the air pump 122 to start and control 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 used to control the control valve 13 to close and the foam pump 123 to start after a first predetermined time period of opening, so as to spray the foam generated by the foam generating assembly 12 from the nozzle 121.

[0112] The control device 60 of the cleaning equipment in this embodiment can respond to triggering the foam spraying mode by controlling the air pump 122 to start and the control valve 13 to open. 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 has been open for a first predetermined period of time, the control valve 13 is closed and the foam pump 123 is started. This means that the air pump 122 runs for a period of time before the control valve 13 is closed, so that the gas from the air pump 122 is not discharged from the second outlet 112, and the foam pump 123 is started. Thus, 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.

[0113] Since it takes a certain amount of time for the air pump 122 to reach full voltage operation from startup, this embodiment of the application first starts the control valve 13 when the foam spraying mode is triggered, connecting the air pump 122 to the second outlet 112. The foam pump 123 starts with a delay. After the control valve 13 has been open for a first predetermined 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 can provide sufficient pressure to the pipeline, thereby avoiding the problem that the foam sprayed under low pressure has a weak spray force and is easy to remain near the nozzle 121. That is, this embodiment of the application can improve the problem of foam residue, extend the service life of the cleaning equipment 1, and facilitate user use.

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

[0115] The third control module is used to respond to the triggering of the stop foam spraying mode, control the foam pump 123 to stop, and control the air pump 122 to keep working so that the foam in the pipeline 11 is sprayed out from the nozzle 121.

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

[0117] The fifth control module is used to control the control valve 13 to close after a third predetermined time period of opening, 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 period of time; wherein the fourth predetermined period of 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 in this embodiment can respond to triggering a stop foam spraying mode, control the foam pump 123 to stop, and after a 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. Control the air pump 122 to stop between the opening and closing of the control valve 13, so that the pressure in the pipeline 11 can be relieved. At the same time, the air pump 122 is turned off, and the pressure in the pipeline 11 can be leaked from the control valve 13 to the standard atmospheric pressure. Then the control valve 13 is closed, so that no foam will be sprayed out and remain at the nozzle of the nozzle 121 due to pressure.

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

[0121] The control device 60 of the cleaning equipment in this application embodiment 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 opened to realize the pressure protection of the pipeline 11.
