Description

Technical Field

[0001] This invention relates to the field of cleaning machines, and more particularly to a control method and equipment for a gasoline-powered cleaning machine. Background Technology

[0002] Gasoline-powered cleaning machines use a gasoline engine as their core power source, driving a plunger pump to generate high-pressure water flow. They can operate stably in remote areas without grid coverage without external mains power.

[0003] Gasoline-powered cleaning machines typically support both tank-fed and natural water source modes. In natural water source mode, without water filtration, impurities will directly enter the high-pressure plunger pump, causing wear, jamming, or even blockage of delicate components such as the plunger, check valve, and seals. This severely shortens the pump's lifespan and can lead to malfunctions. Therefore, current technology usually involves installing a filter at the water inlet of the gasoline-powered cleaning machine to intercept solid impurities in the water.

[0004] However, when the equipment switches to the water tank supply mode, the filter screen structure will create additional resistance to the originally clean water flow, resulting in a significant decrease in water flow rate. It will also cause the gasoline engine to operate under low load conditions for a long time, increasing fuel consumption and carbon buildup risk, and affecting the power matching and operational stability of the entire machine. Summary of the Invention

[0005] To ensure stable operation of a gasoline-powered cleaning machine, this invention provides a control method and equipment for a gasoline-powered cleaning machine.

[0006] In a first aspect, the present invention provides a control method for a gasoline-powered cleaning machine, employing the following technical solution:

[0007] A control method for a gasoline-powered cleaning machine includes:

[0008] In response to a preset insertion signal, the inlet pressure is collected;

[0009] The water source type is determined by analyzing the pressure at the inlet end. The water source types include external water tanks and natural water sources.

[0010] The filtration mode is matched based on the water source type. The filtration modes include open mode and blocking mode.

[0011] When an external water tank is connected, the preset filter structure is retracted in the release mode to allow the liquid in the external water tank to directly enter the preset pump body and be output.

[0012] When connected to a natural water source, the water source type is analyzed and the blocking mode's gear parameters are matched.

[0013] The water source is controlled by different blocking mode parameters according to different water source types so that the water enters the pump body and is output after being treated by the filter structure.

[0014] By adopting the above technical solution, the system analyzes the connected water source based on the inlet pressure to determine the water source type, and automatically adjusts the equipment to the appropriate filtration mode for different water source types. In open mode, the water flow can output maximum flow rate without being affected by filtration. In blocked mode, the system can control the processing unit to filter the water entering the equipment, making it less likely for impurities in the water to affect the equipment, thereby ensuring stable operation of the equipment.

[0015] Optionally, methods for analyzing water source types and matching the blocking mode's gear parameters include:

[0016] In blocking mode, the preset filter box containing sandbags is pushed in and enters the preset inspection stage;

[0017] During the inspection phase, an inspection cycle is set, during which the sandbags continuously receive sand from the water and collect information on the force changes of the sandbags.

[0018] Based on the stress change information of the sandbags and the sediment content information of the water source type matched with the detection cycle;

[0019] Set a baseline sediment concentration, and determine the gear parameters of the blocking mode based on the comparison between the sediment concentration information and the baseline sediment concentration.

[0020] By adopting the above technical solution, the inspection stage and the cleaning stage are set in the blocking mode. In the inspection stage, the water flow is blocked to the greatest extent to prevent impurities from directly entering the equipment. Then, the sand entering the sandbag is continuously tested, so that the sand content can be tested to match the gear parameters without affecting the normal cleaning process of the equipment.

[0021] Optionally, the gear parameters include gears with excessive sand content, and the control methods under the gear with excessive sand content include:

[0022] During the pre-set cleaning phase, the sandbags are kept in the pushing state and the force information of the sandbags is continuously collected;

[0023] Match the sand storage capacity of the sandbags according to the stress information of the sandbags;

[0024] Set parameters for the sand storage volume early warning stage, and compare the sand storage volume of the sandbags with the parameters for the sand storage volume early warning stage to match the sand storage stage;

[0025] The system matches early warning strategies based on the sand storage stage and outputs early warning strategies.

[0026] By adopting the above technical solution, when there is a lot of sand in the water, the sandbags are kept in a pushing state to continuously block and receive the sand. Then, by collecting the amount of sand in the sandbags, the current amount of sand in the sandbags can be determined in real time, so that users can deal with the sand in the sandbags in a timely manner without affecting the normal operation of the equipment.

[0027] Optional, also includes:

[0028] Record the user's historical maximum water consumption and set it as the user's preferred consumption level;

[0029] The proportion of sand in the filter box is determined based on the sand storage capacity of the sandbag and the preset filter box volume.

[0030] The pipe flow rate is matched according to the proportion of sand and soil space.

[0031] When the water flow rate in the pipeline is less than the user's usual flow rate, a flow warning will be issued, and the water flow rate in the pipeline will continue to be monitored.

[0032] In response to a preset water outlet signal, the system retrieves the user's required flow rate based on the water outlet signal.

[0033] When the water flow rate in the pipeline is less than the user's required flow rate, a low flow rate warning will be issued, and a sandbag replacement request will be issued after a preset waiting time.

[0034] By adopting the above technical solution, the system records the user's historical maximum water flow in real time and uses this as the user's habit. Then, it monitors the water flow in the pipeline in real time based on the user's habit. If the flow in the pipeline cannot meet the habitual operation of some users, the system will issue a prompt. Conversely, the system will detect the user's actual demand flow during use. If the water flow in the pipeline is less than the user's demand flow, the system will issue a warning.

[0035] Optionally, methods for handling foreign objects entering during blocking mode include:

[0036] Collect the real-time water flow rate behind the filter box;

[0037] When the real-time water flow rate is less than the pipe water flow rate, it is defined as foreign object blockage, and the inlet side of the filter box is opened to allow foreign objects to enter the filter box.

[0038] Switch the filter mode from blocking mode to releasing mode to eject the filter box;

[0039] After removing the foreign objects from the filter box, reset the filtration mode to the blocking mode.

[0040] By adopting the above technical solution, the system can determine whether foreign objects have entered the pipeline by judging whether the real-time water flow rate behind the filter box is less than the real-time water flow rate. When it is determined that foreign objects have entered, the system can automatically collect the foreign objects into the filter box and switch modes to remove the filter box for the user to handle the foreign objects.

[0041] Optional, also includes:

[0042] Acquire images of the objects to be cleaned;

[0043] Identify the type of object to be cleaned from the image of the object being cleaned;

[0044] Match the maximum threshold of sand content based on the type of object being cleaned;

[0045] When the sediment content of the water source exceeds the maximum sediment content threshold, the preset water discharge signal will not be responded to.

[0046] By adopting the above technical solution, when a user uses a cleaning gun to clean an object, the system can identify the object and determine if it has special requirements that necessitate the use of clean water. For objects with special requirements, the system will detect the sand content of the water source. If the conditions are not met, the system will automatically refuse to respond to the water dispensing signal, thus preventing water from being dispensed and avoiding damage to the object being cleaned.

[0047] Secondly, this application provides a gasoline-powered cleaning machine, which adopts the following technical solution:

[0048] A gasoline-powered cleaning machine is controlled using any of the above-mentioned gasoline-powered cleaning machine control methods. It includes a plunger pump unit, a fuel power unit for providing power to the plunger pump unit, and an output unit driven by the plunger pump unit to output liquid. It also includes a treatment unit connected to the water inlet of the output unit for selectively filtering the water entering the output unit.

[0049] By adopting the above technical solution and setting up a processing unit, the system can selectively filter water when it enters the equipment, thus ensuring the stable operation of the gasoline-powered cleaning machine.

[0050] Optionally, the processing unit includes a connection end connected to an external water source pipeline, a spiral centrifugal section connected to the connection end and used to actively rotate the water flow to centrifuge the sand in the water, and a filter collection section connected to the spiral centrifugal section and used to filter and collect the sand in the water.

[0051] By adopting the above technical solution, the water source can rotate and form a vortex after entering the spiral centrifugal section. The sand in the water can be centrifuged in the vortex and thrown to the surrounding pipe wall, thereby separating the sand from the water for sand treatment.

[0052] Optionally, the filtration and collection section includes a filter housing, an inlet pipe connected to the inlet end of the filter housing, a filter screen box that is lifted and lowered in the inner cavity of the filter housing, a sand storage bag that is detachably installed in the filter screen box, and a drive component installed on the housing for driving the filter screen box to move.

[0053] The filter housing has a lifting channel inside for moving the filter box, and the lifting channel has a filtration station and a storage station;

[0054] The water inlet pipe includes an inner pipe and an outer pipe connected to the inner pipe. A sand cavity is formed between the inner pipe and the outer pipe for centrifugal sand to enter. A sand pipe for sand to pass through is provided between the sand cavity and the receiving station of the lifting channel, and the sand pipe has an opening and closing valve. The sand storage bag has an inlet for sand to enter at the top of the filter box.

[0055] The sand chamber, filter box, and sand storage bag are all equipped with filter holes for water flow.

[0056] The connection end is equipped with a detection element, and the detection element, the opening and closing valve, and the driving element are electrically connected.

[0057] By adopting the above technical solution, in the blocking mode, the filter box can perform preliminary filtration of the water source and block large foreign objects from entering the equipment. After the water flow is rotated and centrifuged through the spiral pipe, the sand in the water can enter the sand storage bag through the bypass sand pipe for collection. The sand storage bag is located in the filter box, and the sand in the sand storage bag can further filter the water flow in the pipe again.

[0058] Optionally, the output unit has a return water valve, and the output unit is connected to the connection end through the return water valve; the fuel power unit has a cold water tank for absorbing heat, and the cold water tank is connected to the output unit and performs water circulation.

[0059] The water in the cold water tank is heated by absorbing heat from the fuel power unit. When the heated water flows through the treatment unit, plunger pump unit and output unit, it can soften the scale on the inner wall, thus making it easier to treat the scale.

[0060] In summary, this application includes at least one of the following beneficial technical effects:

[0061] The system analyzes the connected water source based on the inlet pressure to determine the water source type, and automatically adjusts the equipment to the appropriate filtration mode for that water source type. In open mode, the water flow can output maximum flow rate without being affected by filtration. In blocked mode, the system controls the processing unit to filter the water entering the equipment, making it less likely for impurities in the water to affect the equipment, thereby ensuring stable operation.

[0062] In blocking mode, the filter box can perform preliminary filtration of the water source and block large foreign objects from entering the equipment. After the water flow is rotated and centrifuged through the spiral pipe, the sand in the water can enter the sand storage bag through the bypass sand pipe for collection. The sand storage bag is located in the filter box, and the sand in the sand storage bag can further filter the water flow in the pipe again. Attached Figure Description

Detailed Implementation

[0067] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0068] This application discloses a gasoline-powered cleaning machine.

[0069] Reference Figure 1A gasoline-powered cleaning machine includes a fuel power unit 1, a plunger pump unit 2, an output unit 3, and a processing unit 4. The fuel power unit 1 provides power by burning gasoline, converting heat energy into kinetic energy to drive the output unit's rotation. The plunger pump unit 2 is a plunger pump connected to the output unit 1 via a reducer, and is used for pumping fluid. The output unit 3 is connected to the plunger pump unit 2 and has an inlet 31 and an outlet 32. Driven by the plunger pump unit 2, the output unit 3 receives water through the inlet 31 and outputs pressurized water through the outlet 32. The outlet 32 ​​of the output unit 3 can be connected to a cleaning gun. The processing unit 4 is connected to the inlet 31 of the output unit 3 and is used to process the water entering the output unit 3.

[0070] Reference Figure 1 and Figure 2 The processing unit 4 includes a connection end 41, a spiral centrifugation section 42, and a filtration and collection section 43.

[0071] The connection end 41 serves as a connector to an external water source pipeline, and a detection element 411 is provided on it for detecting the type of water source. This will not be elaborated here, but will be described in detail in subsequent embodiments.

[0072] The spiral centrifugal section 42 is fixedly connected to the connecting end 41. It is pipe-shaped and used to supply water flow. The internal channel of the spiral centrifugal section 42 is spiral-shaped, which allows the water flow to rotate and generate vortex output when it flows through. When the water contains sand, the sand can be thrown to the surrounding pipe wall under the centrifugal action of the vortex.

[0073] Reference Figure 1 , Figure 2 and Figure 3 The filtration and collection section 43 includes a filter housing 431, an inlet pipe 432, a filter screen box 433, a sand storage bag 434, a drive component 435, and a sand pipe 436.

[0074] The water inlet pipe 432 is integrally connected to the water inlet end of the filter housing 431. One end of the filter housing 431 is fixedly connected to the spiral centrifugal section 42 through the water inlet pipe 432, and the other end is connected to the water inlet 31 of the output unit 3.

[0075] The inlet pipe 432 includes an inner pipe 4321 and an outer pipe 4322. The outer pipe 4322 is fixedly sleeved on the outside of the inner pipe 4321, forming a sand cavity 4323 between the inner pipe 4321 and the outer pipe 4322. The opening of the sand cavity 4323 faces the spiral centrifugal section 42. The inner pipe 4321 extends through both ends, and one end of the sand cavity 4323 has a filter hole. When water enters the inlet pipe 432, the water can flow through the inner pipe 4321 and the sand cavity 4323 and enter the filter housing 431. However, the sand centrifuged by the vortex is thrown against the circumferential pipe wall and then enters the sand cavity 4323.

[0076] The filter housing 431 is hollow inside and has a lifting channel 4211. The channel through which the water flows in the filter housing 431 is connected to the lifting channel 4211 and is orthogonally arranged.

[0077] The filter box 433 is installed in the lifting channel 4211. It is hollow inside and has an array of filter holes at both ends, allowing water to flow through the filter box 433.

[0078] The drive unit 435 is an electric push rod, which extends into the lifting channel 4211 and connects to the filter box 433. The lifting channel 4211 has a filtration station and a storage station. The filtration station is directly opposite the water supply channel in the filter housing 431, while the storage station is offset from the water supply channel in the filter housing 431. The drive unit 435 can drive the filter box 433 to switch between the filtration station and the storage station.

[0079] The sandbag 434 is used to collect sand and has filter holes around its circumference for water to flow through. The sandbag 434 is detachably installed inside the filter box 433, and the inlet of the sandbag 434 is located at the top of the filter box 433.

[0080] The sand pipe 436 serves as a bypass pipe, connecting the sand chamber 4323 of the inlet pipe 432 to the receiving station of the lifting channel 4211. An opening and closing valve 437 is installed on the sand pipe 436 to control its opening and closing.

[0081] In this embodiment, the detection element 411, the opening / closing valve 437, and the driving element 435 are all electrically connected. The detection element 411 serves as a data acquisition element, while the opening / closing valve 437 and the driving element 435 serve as actuation elements, all controlled by the system. The detection element 411, the opening / closing valve 437, and the driving element 435 are all powered by the device's built-in low-voltage power supply.

[0082] When the detection element 411 detects that the connection end 41 is directly connected to a natural water source, the driving element 435 drives the filter box 433 and the sand bag 434 to the filtration position, and the opening / closing valve 437 opens. At this time, water can flow through the filter holes of the filter box 433 and the sand bag 434, while sand can pass through the sand chamber 4323, the sand pipe 436, and the collection position in sequence, and finally enter the sand bag 434 for collection. Since the sand bag 434 is also in the channel through which the water flows when it is in the filtration position, the sand bag 434 can further filter the passing water.

[0083] When the detection component 411 detects that the connection end 41 is connected to the external water tank, the driving component 435 drives the filter box 433 and the sand bag 434 to the storage position for storage, and the opening and closing valve 437 is closed. At this time, the water supply from the filter housing 431 can pass directly through the channel without filtration to ensure the water flow rate.

[0084] In this embodiment, the output unit 3 has a return water valve 5, and the output unit 3 is connected to the connection end 41 through the return water valve 5 and the pipe. When the outlet 32 ​​of the output unit 3 is closed and the water pressure in the output unit 3 reaches the specified threshold pressure, the return water valve 5 automatically opens. At this time, the water flow in the output unit 3 can return to the connection end 41 and re-enter the output unit 3 through the plunger pump unit 2, thereby realizing the water flow circulation when the outlet 32 ​​of the output unit 3 is closed.

[0085] The fuel-powered unit 1 has a cold water tank for absorbing heat and cooling. The cold water tank is connected to the output unit 3 and circulates water. The water in the cold water tank is heated by absorbing heat from the fuel-powered unit 1. When the heated water flows through the treatment unit 4, the plunger pump unit 2, and the output unit 3, it can soften the scale on the inner wall, thus facilitating the treatment of the scale.

[0086] Based on the same inventive concept, embodiments of the present invention provide a control method for a gasoline-powered cleaning machine.

[0087] A control method for a gasoline-powered cleaning machine includes the following steps:

[0088] Step S1: In response to the preset insertion signal, the pressure at the inlet end is collected.

[0089] The insertion signal refers to the system signal triggered when an external water source pipe connects to the connection terminal 41 of the equipment. When the system detects the insertion signal, it indicates that an external water source has been connected, and the pressure at the inlet end begins to be collected.

[0090] The inlet pressure refers to the water pressure when water from the external water source pipe enters the connection end 41. The inlet pressure is collected by a detection element 411 installed on the connection end 41. The detection element 411 is a pressure sensor.

[0091] Step S2: Analyze the pressure at the inlet end to determine the water source type, which includes external water tanks and natural water sources.

[0092] The water source type refers to the type of water source supplying the gasoline-powered cleaning machine. An external water tank means the water source is directly contained in a water tank or bucket, which is then directly connected to the connection terminal 41 of the gasoline-powered cleaning machine. The water in the external water tank is clean and requires no filtration. A natural water source refers to water from natural sources such as rivers, ponds, and ditches. A pipe is extended into the natural water source and connected to the connection terminal 41 of the gasoline-powered cleaning machine. Natural water sources contain impurities such as sand and soil and require filtration.

[0093] Because the external water tank uses a closed water supply system, the pressure is stable and low. In contrast, natural water sources are pumped water supplies, resulting in large pressure fluctuations and high pressure readings. By analyzing the pressure characteristics of the inlet end, the type of water source can be determined.

[0094] Step S3: Match the filtration mode based on the water source type. The filtration modes include open mode and blocking mode.

[0095] Filtration mode refers to how the equipment treats different types of water sources. Open mode means the water source enters the equipment directly without filtration. Blocking mode means the water source passes through treatment unit 4 for filtration before entering output unit 3.

[0096] Once the water source type is determined, different filtration modes are matched based on whether filtration is required for the connected water source.

[0097] Step S4: With the external water tank connected, retract the preset filter structure in the release mode to allow the liquid in the external water tank to directly enter the preset pump body and be output.

[0098] The filtration structure refers to the filter box 433 and sandbag 434 in the treatment unit 4.

[0099] In this embodiment, when the device is supplied with water by an external water tank, the filter structure is retracted so that the water flow can directly enter the plunger pump unit 2 for pumping without filtration.

[0100] Step S5: When connected to a natural water source, analyze the water source type and match the blocking mode gear parameters.

[0101] Because the impurity content of natural water sources varies, using a single filtration standard can easily lead to situations such as "insufficient filtration causing pump wear" or "over-filtration causing flow obstruction again." Therefore, filtration must be carried out according to the actual situation of the water source. The filter parameters are the filtration parameters set for different types of water sources with different impurity contents.

[0102] The setting parameters include a baseline sediment concentration setting and a sediment concentration exceeding the standard setting. The baseline sediment concentration setting is mainly for natural water sources with low sediment content. At this setting, the sandbag 434 is retracted, and only the filter box 433 remains for water filtration. The sediment concentration exceeding the standard setting is mainly for natural water sources with high sediment content. At this setting, both the sandbag 434 and the filter box 433 are located in the pipeline and simultaneously filter the water. The setting parameters of the blocking mode can analyze and determine the sediment content of different water source types.

[0103] Step S6: Control the water source according to different water source types using different blocking mode parameters so that the water enters the pump body and is output after being treated by the filter structure.

[0104] When connected to a natural water source, the system first detects the sediment content of the natural water source, and then selects different blocking mode parameters to adapt to water sources with different sediment contents.

[0105] The method for analyzing water source types and matching the blocking mode's gear parameters includes the following steps:

[0106] Step S50: In blocking mode, push in the preset filter box 433 containing the sandbag 434 and enter the preset inspection stage.

[0107] The pre-inspection phase is a dedicated operating phase under the blocking mode, preceding the cleaning phase before normal equipment operation. During this phase, the primary step is to test the sand content of the water source. In this stage, both the sandbag 434 and the filter box 433 are pushed into the pipeline to block the water flow, treating the highest possible sand content as the initial scenario. After determining the sand content, the appropriate settings are then configured based on the actual sand content of the water source.

[0108] Step S51: During the inspection phase, a detection cycle is set. During the detection cycle, the sandbag 434 continuously receives sand from the water and collects information on the force changes of the sandbag 434.

[0109] The testing cycle is the time length of the testing phase preset by the technicians, which is sufficient for the equipment's sensors to detect the sand content of the water source.

[0110] The force change information of the sandbag 434 refers to the force exerted by the sand on the sandbag 434 when it is filled with sand. The magnitude of the force is determined by the weight of the sand. The change in the force exerted by the sand on the sandbag 434 per unit time is the force change information of the sandbag 434. A pressure sensor is installed on the filter box 433, which can collect the tensile force on the sandbag 434. By continuously detecting the tensile force on the sandbag 434 and combining it with the detection cycle, the force change information of the sandbag 434 is obtained.

[0111] Step S52: Based on the stress change information of the sandbag 434 and the detection cycle, match the sediment content information of the water source type.

[0112] Sediment content information refers to the amount of sand and soil contained in a unit volume of water source.

[0113] The stress change information of sandbag 434 is specifically represented by the amount of sand entering sandbag 434 per unit time. The sand content information is directly proportional to the stress change information; the greater the stress change information of sandbag 434, the greater the sand content information.

[0114] Step S53: Set the reference sand content, and determine the gear parameters of the blocking mode based on the comparison relationship between the sand content information and the reference sand content.

[0115] The baseline sediment concentration is a parameter preset by technicians to measure the cleanliness of natural water sources, and will not be elaborated upon here. When the sediment concentration in the natural water source is not greater than the baseline sediment concentration, it indicates that the natural water source is clean, and the blocking mode setting should be adjusted to the baseline sediment concentration setting. If the sediment concentration in the natural water source is greater than the baseline sediment concentration, it indicates that the natural water source contains a lot of impurities and sand, and the blocking mode setting should be adjusted to the excessive sediment concentration setting.

[0116] The gear parameters include gears with excessive sand content, and the control methods under gears with excessive sand content include:

[0117] Step S600: During the preset cleaning phase, the sandbag 434 remains in the pushing state and the force information of the sandbag is continuously collected.

[0118] The cleaning phase is the stage set by the technicians for normal equipment operation, during which the equipment's outlet 32 ​​is cleaned by spraying liquid through a cleaning gun.

[0119] When the sand content of the natural water source is high, the system will maintain the sandbag 434 and filter box 433 in a pushed-in state, and treat the natural water source synchronously through the sandbag 434 and filter box 433. The force information of the sandbag corresponds to the force change information of the sandbag 434, which refers to the real-time tension of the sandbag 434 on it caused by the sand inside. The force information of the sandbag is acquired by sensors installed on the filter box 433.

[0120] Step S601: Match the sand storage capacity of the sandbags according to the stress information of the sandbags.

[0121] The sand storage capacity of the sandbags refers to the amount of sand collected in the sandbags 434. The sand storage capacity is directly proportional to the stress information of the sandbags; the greater the stress information, the greater the sand storage capacity. During the cleaning phase, the system monitors the amount of sand in the sandbags 434 in real time to prevent sand from clogging them.

[0122] Step S602: Set the parameters for the sand storage volume early warning stage, and compare the sand storage volume of the sandbags with the parameters for the sand storage volume early warning stage to match the sand storage stage.

[0123] The sand storage volume warning stage parameters are preset by technicians and refer to the warning alarm parameters that will be triggered when the sand storage volume in the sandbags reaches a specified threshold. The sand storage volume warning stage parameters include multiple stages, changing in a step-like manner. Each time the sand storage volume in the sandbags reaches one of the warning stage parameters, the equipment will issue an alarm to prompt personnel to take action.

[0124] The sand storage stage is divided according to the amount of sand in the sandbag 434, and each sand storage stage corresponds one-to-one with the sand storage volume warning stage parameters. By determining which sand storage volume warning stage parameter range the sandbag 434 falls into, the current sand storage stage can be determined.

[0125] Step S603: Match the early warning and prompt strategy based on the sand storage stage, and output the early warning and prompt strategy.

[0126] The early warning strategy employs different alarm methods based on the amount of sand stored. The higher the sand content in the sandbag 434, the different forms of early warning alerts the system issues. In this embodiment, the specific early warning strategy mainly involves variations in the frequency of alerts. Higher sand storage levels and stages result in more frequent early warning alerts.

[0127] The treatment method for water flow rate reduction due to increased sand content includes the following steps:

[0128] Step S610: Record the user's historical maximum water consumption and set it as the user's habitual water consumption.

[0129] The historical maximum water flow rate refers to the maximum flow rate a user has ever used when performing cleaning operations with the gasoline-powered cleaner. The user-controlled water flow rate is determined by the pressure applied by the user to the button on the cleaning gun. The system records the user's water flow rate each time they use the gasoline-powered cleaner and analyzes this data to determine the historical maximum water flow rate. The user's habitual water flow rate refers to the water flow rate the user typically uses when using the gasoline-powered cleaner. This habitual flow rate is set by the system, which uses the user's historical maximum water flow rate as its reference.

[0130] Step S611: Determine the proportion of sand space in filter box 433 based on the sand storage capacity of the sandbag and the preset filter box volume.

[0131] The volume of the filter box is the internal volume of the filter box 433, which is also equal to the volume of the pipe in which the filter box 433 is located.

[0132] The sand space ratio refers to the proportion of space occupied by sand within the filter box 433. The sand space ratio is the quotient of the sand storage capacity of the sandbag and the volume of the filter box.

[0133] Step S612: Match the pipe flow rate according to the proportion of sand and soil space.

[0134] The water flow rate in the pipeline refers to the flow rate of water passing through a filter box containing sand (433). The water flow rate is inversely proportional to the proportion of sand in the filter box. The higher the proportion of sand in the filter box, the smaller the cross-sectional area of ​​the pipeline, and the lower the water flow rate.

[0135] Step S613: When the water flow rate in the pipeline is less than the user's usual flow rate, issue a flow warning and continue to monitor the water flow rate in the pipeline.

[0136] When the water flow rate through the pipeline is not less than the user's usual flow rate, it indicates that the water flow rate output by the equipment is large enough to meet the user's water usage habits. When the water flow rate through the pipeline is less than the user's usual flow rate, some users may be accustomed to using their usual flow rate for cleaning, which will affect these users. Therefore, the system will issue a flow warning to inform these users that the sand in the sandbag 434 needs to be treated.

[0137] If the water flow rate in the pipeline does not affect the user, the system will continue to monitor the water flow rate in the pipeline.

[0138] Step S614: In response to the preset water outlet signal, retrieve the user's required flow rate based on the water outlet signal.

[0139] The water outlet signal refers to the trigger signal for the user to turn on the cleaning gun. After receiving the signal, the equipment system retrieves the user's required flow rate for this operation, which is the user's required flow rate. The user's required flow rate is obtained by the system analyzing the water outlet signal. After the system confirms the water outlet signal, it will open the water outlet 32 ​​of output unit 3, and water will spray out from the cleaning gun.

[0140] Step S615: When the water flow rate in the pipeline is less than the user's required flow rate, a low flow rate warning is issued, and a sandbag 434 replacement request is issued after a preset waiting time.

[0141] When the water flow rate in the pipeline is not less than the user's required flow rate, the equipment can provide a sufficient flow rate and operate normally. When the water flow rate in the pipeline is less than the user's required flow rate, the system cannot output the required flow rate to the cleaning gun through the equipment. At this time, the system will issue a low flow rate warning, informing the user that the flow rate is insufficient and the sand in the sandbag 434 needs to be treated.

[0142] The waiting time is a parameter preset by the technicians, representing the waiting period after the system issues a low flow warning. After the waiting time, the equipment's processing unit 4 sends a replacement request, demanding the replacement of the sandbag 434.

[0143] The procedure for handling foreign objects entering the device in blocking mode includes the following steps:

[0144] Step S620: Collect the real-time water flow rate behind the filter box 433.

[0145] A flow sensor is installed on the outlet side of the filter box 433 to collect the water flow rate in real time. The real-time water flow rate can be used as a basis for determining whether the filter box 433 is clogged.

[0146] Step S621: When the real-time water flow rate is less than the pipe water flow rate, it is defined as foreign object blockage. The inlet side of the filter screen box 433 is opened to allow foreign objects to enter the filter screen box 433.

[0147] When the real-time water flow rate is not less than the pipe flow rate, it indicates that the water flow rate through the filter box 433 is normal, and only the filter box 433 and the sandbag 434 are obstructing the water flow. In this situation, the system will continuously monitor the flow rate and prompt the user to adjust the sandbag 434 as needed.

[0148] When the real-time water flow rate is less than the pipe flow rate, it may be because large foreign objects in the natural water source are sucked into the pipe and attached to the surface of the filter box 433 when the equipment is connected to the natural water source. At this time, most of the filter holes of the filter box 433 are blocked by foreign objects, which affects the water flow of the filter box 433, thus causing the real-time water flow rate to be less than the pipe flow rate.

[0149] In this embodiment, the side of the filter box 433 facing the connection end 41 can slide upward under the action of the driving member 435, thereby opening the filter box 433. When the filter box 433 is opened, foreign objects can enter the filter box 433.

[0150] Step S622: Switch the filter mode from blocking mode to releasing mode to remove the filter box 433.

[0151] When foreign objects enter the filter box 433, the system switches from blocking mode to releasing mode. In releasing mode, the filter box 433 can move upward from the filtration station to the storage station. At the storage station, there is a cleaning port, which the user can open to clean the foreign objects in the filter box 433.

[0152] The equipment was shut down during the cleaning process.

[0153] Step S623: After removing the foreign objects from the filter box 433, reset the filtration mode to the blocking mode.

[0154] After removing foreign objects, reset the filtration mode to allow the equipment to continue operating.

[0155] The handling methods when the object to be cleaned has cleaning requirements include:

[0156] Step S630: Acquire an image of the object to be cleaned.

[0157] The image of the object being cleaned refers to the image captured by a miniature camera mounted on the cleaning gun. When the cleaning gun is pointed at the object to be cleaned, the system can capture an image through the miniature camera.

[0158] Step S631: Identify the type of object to be cleaned from the image of the object to be cleaned.

[0159] A database of objects to be cleaned is pre-set, and images of these objects are analyzed and identified using image recognition algorithms to determine their type. Object types can include precision equipment, automotive paintwork, construction machinery, and concrete floors, among others.

[0160] Step S632: Match the maximum threshold of sand content based on the type of object being cleaned.

[0161] Because some types of surfaces requiring cleaning need protection, such as car paint, sand in the water source can damage the surface being cleaned. Therefore, the sand content in the water source needs to be limited according to the type of object being cleaned; this limit is the maximum sand content threshold.

[0162] Step S633: When the sediment content information of the water source type exceeds the maximum sediment content threshold, refuse to respond to the preset water discharge signal.

[0163] After the system first determines the type of object to be cleaned and the maximum sand content threshold, it then analyzes the sand content of the water source. If the sand content of the water source does not exceed the maximum sand content threshold, then that water source type can be directly used to clean the object. If the sand content of the water source exceeds the maximum sand content threshold, then the sand content in the water source is too high and cannot be directly used to clean the object. In this case, when the user presses the button on the cleaning gun, the system refuses to respond to the water dispensing signal and no water is dispensed. The system will also issue a warning to protect the object being cleaned.

All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention.
