Along with the diversification of people's demands, the multiple functions have been realized to current intelligent cleaning device, consequently can be applicable to a plurality of application scenarios. The inventor finds that when the existing intelligent cleaning equipment simultaneously starts the disinfection function of high-temperature steam and synchronously performs the cleaning function of dust collection, part of steam and dirt can be sucked away simultaneously, so that the cleaning efficiency is influenced. To improve or solve the above-described problems, at least the following embodiments are proposed in the present application.

An exemplary structure of a cleaning apparatus is described below for embodiments of the cleaning apparatus of the present application.

The cleaning device 1 may be a device having at least one of the functions of dust collection, floor sweeping, floor mopping and floor washing. For example, the cleaning device 1 may be a cleaner 1 such as a vacuum cleaner, a sweeper, a mopping machine, a floor washing machine, or a robot having sweeping and mopping functions, or may be a robot integrating suction, mopping and washing. As shown in fig. 1, 2 and 3, the cleaning device 1 includes a housing 100, a liquid supply assembly 200, and a stain adsorption assembly 300. The liquid supply unit 200 and the stain adsorption unit 300 may be disposed in the housing 100 and connected to the outside through a separate passage, and the liquid supply unit 200 may be filled with water from a water tap, for example. At least one of the liquid supply assembly 200 and the stain adsorption assembly 300 can be detachably arranged outside the casing 100, so that liquid can be conveniently added into the liquid supply assembly 200, and stains in the stain adsorption assembly 300 can be conveniently poured and cleaned. Optionally, the cleaning device 1 may further comprise a liquid mixer (not shown).

The housing 100 includes a main body housing 110 and a cleaning housing 120 connected to each other. The stain adsorption assembly 300 in the main machine housing 110 includes a stain receiving chamber 310 and a suction assembly 320. The cleaning housing 120 encloses an accommodating space 121, and a cleaning assembly 130 and a steam generating assembly 140 are disposed in the accommodating space 121. The cleaning housing 120 is opened with a suction port 150. Wherein the suction opening 150 and the steam generation assembly 140 may be disposed on opposite sides of the cleaning assembly 130. The housing 100 is further provided with a suction passage 160 communicating the suction port 150 and the stain receiving chamber 310. The suction passage 160 has a connection passage 161 at the connection of the main body case 110 and the cleaning case 120.

The main body case 110 may be held by a user. The cleaning housing 120 is used to contact and clean the area to be cleaned, for example, by spraying, rubbing, and adsorbing the area to be cleaned. The main body housing 110 and the cleaning housing 120 are rotatably connected, for example, and a user can adjust a posture of use by adjusting a connection angle of the main body housing 110 and the cleaning housing 120. The user can push the main housing 110 to drive the cleaning housing 120 to move in the region to be cleaned, so as to clean the region to be cleaned.

As shown in fig. 4, the main body case 110 may include an accommodating sub-case 111 and a grip sub-case 112 connected in sequence in a length direction, and the accommodating sub-case 111 may be connected with the cleaning case 120. One end of the accommodating sub-housing 111 away from the cleaning housing 120 is connected to the holding sub-housing 112, and the accommodating sub-housing 111 can accommodate the liquid supply assembly 200, the dirt adsorption assembly 300, the liquid mixer (not shown), and the like. The area of the cross section of the grip sub-housing 112 perpendicular to the length direction of the main housing 110 may be smaller than the area of the cross section of the accommodation sub-housing 111 perpendicular to the length direction of the main housing 110, so as to be gripped by a user. The holding sub-housing 112 may have a first holding portion 113 at an end thereof away from the accommodating sub-housing 111 for a user to hold. The first grip portion 113 may be provided in a bent shape, for example. The accommodating sub-housing 111 may be provided with a second holding portion 114 at an end thereof close to the holding sub-housing 112 for being held by the other hand of the user. The second grip portion 114 may be provided in a ring shape, for example. When the user uses the cleaning device 1, the left hand can be held at the second holding part 114, the right hand can be held at the first holding part 113, the left hand and the right hand are staggered to cooperate, and the cleaning shell 120 can be pushed by the main machine shell 110. The second holding portion 114 can also be used for moving the cleaning device 1, for example, a user holds the second holding portion 114 and places the cleaning device 1 originally placed on the ground on a charging seat for charging.

As shown in fig. 2, 3 and 4, the cleaning assembly 130 is used to contact the cleaning region to be cleaned for cleaning, and the liquid supply assembly 200 is used to spray liquid to the cleaning assembly 130 through the liquid spray port 141. The cleaning assembly 130 may include a roll brush, a broom, a mop, a wipe, etc. The cleaning assembly 130, such as a roller brush, is rotatably disposed in the accommodating space 121 and is driven to rotate by a motor (not shown) that may be fixed to the cleaning housing 120. The bottom of the cleaning housing 120 is provided with an installation space 122, and the suction port 150 faces and communicates with the installation space 122 for accommodating the cleaning assembly 130. Alternatively, the installation space 122 may be located in the accommodating space 121. The mounting space 122 has an opening 123, and the cleaning assembly 130 is rotatably received in the mounting space 122 and at least partially exposed through the opening 123. The cleaning assembly 130, such as a roller brush, may be used to contact the area to be cleaned and thereby wipe the area to be cleaned in a rolling friction manner. Optionally, the number of cleaning assemblies 130 is at least one. The number of the cleaning assembly 130, for example, the roll brush may be one or more, and in many cases, a plurality of roll brushes may be spaced side by side. The cleaning housing 120 is provided with a liquid ejecting port 141 spaced apart from the suction port 150. The liquid spray port 141 may be disposed toward the cleaning assembly 130 to spray liquid toward the cleaning assembly 130, so that the cleaning assembly 130 is wetted and the cleaning assembly 130 can perform wet cleaning on an area to be cleaned. Optionally, the liquid spraying port 141 may also be directly disposed toward the outside of the opening of the accommodating space 121, so as to directly spray the liquid to the area to be cleaned, thereby performing functions of wetting, flushing, and the like.

The liquid supply assembly 200 is disposed at the main body case 110 and may be used to supply a corresponding liquid to the cleaning case 120. The liquid supply assembly 200 includes a liquid container 210 and a water pump 220, the liquid container 210 can be used for containing liquid, and the water pump 220 can be used for delivering the liquid in the liquid container 210 to the cleaning housing 120. Alternatively, the liquid supply assembly 200 may spray liquid through the liquid spray port 141 to clean the region to be cleaned by the liquid. The liquid supply assembly 200 may also be used to provide liquid to the steam generating assembly 140. The steam generating assembly 140 includes a heating device 142 and a steam outlet 143. Wherein, the steam outlet 143 is opened at the bottom of the cleaning housing 120, spaced apart from the opening 123, and is used for outputting the steam of the steam generating assembly 140. The liquid supply assembly 200 supplies liquid to the heating device 142, and the heating device 142 converts the liquid into steam and outputs the steam to the area to be cleaned through the steam outlet 143, thereby performing high-temperature sterilization and stain softening. Optionally, the number of water pumps 220 is at least one. For example, the number of the water pumps 220 may be two, one water pump 220 is used to supply the liquid to the liquid spray port 141, and the other water pump 220 is used to supply the liquid to the steam generating module 140. However, when cleaning an area having the same area, the amount of liquid used when converting the liquid into steam is smaller than the amount of liquid used when directly using the liquid, and therefore, the amount of liquid to be supplied to the liquid ejecting port 141 is larger than the amount of liquid to be supplied to the steam generating module 140, that is, two different water pumps 220 need to be used. The liquid supplied by the liquid supply assembly 200 may include a cleaning agent, a cleaning liquid, etc., in addition to fresh water. Wherein the cleaning liquid is obtained by mixing clean water with a cleaning agent. Optionally, the number of liquid containers 210 is at least one. For example, the liquid containers 210 may be two in number, and may be used to supply at least two liquids to a liquid mixer (not shown). The liquid mixer (not shown) may mix, blend, etc. at least two liquids to obtain a mixed cleaning liquid. The mixed cleaning liquid can be sprayed to the cleaning region through at least one of the liquid spraying opening 141 and the steam outlet 143 after being output to the cleaning housing 120, so that the cleaning housing 120 can perform a cleaning process on the cleaning region using the cleaning liquid.

The stain adsorption assembly 300 can adsorb stains such as garbage on an area to be cleaned, waste water generated during cleaning, and the like during cleaning of the area to be cleaned. The suction assembly 320 is used to suck the soil of the area to be cleaned into the soil accommodating chamber 310 through the suction opening 150 and the suction channel 160. The suction assembly 320, the dirt holding chamber 310 and the suction opening 150 can be directly connected, and dirt such as water and garbage can enter from the suction opening 150 and be directly introduced into the dirt holding chamber 310 under the suction action of the suction assembly 320. Optionally, a pipeline may be disposed between the dirt holding cavity 310 and the suction opening 150, and dirt such as water and garbage enters from the suction opening 150 through the pipeline and then enters the dirt holding cavity 310 under the suction action of the suction assembly 320. Optionally, the suction assembly 320, the stain receiving chamber 310, and the cleaning assembly 130 can be connected to absorb stains such as waste water generated during the cleaning process of the cleaning assembly 130 on the area to be cleaned and garbage on the area to be cleaned. For example, the drum brush 131 may leave a part of dirt such as sewage adsorbed to the drum brush 131 or hair adhered to the drum brush 131 when cleaning is performed, and the dirt may not directly pass through the suction opening 150. The soil on the roll brush 131 enters the soil accommodating chamber 310 through the communication passage 161 between the soil accommodating chamber 310 and the roll brush 131 by the suction action of the suction assembly 320. Alternatively, the dirt holding cavity 310 may filter the airflow, and the filtered airflow is discharged out of the holding sub-housing 111.

Further, a detection sensor 170 is disposed in the housing 100, and the detection sensor 170 may be, for example, an infrared pair sensor. Alternatively, the infrared pair tube sensor may be fixed or may be movable. In the infrared pair tube sensor, at least one emitter and at least one receiver are provided, wherein the emitter can emit infrared signals, the receiver can receive the infrared signals, when the passing or remaining dirt condition is increased, the infrared rays can be shielded by the dirt, and the intensity of signals received by the receiver can be reduced or even disappear. The signal strength variation received by the receiver can be used to determine whether a blockage condition exists and the degree of the blockage, i.e., can be used to detect a passing or remaining soil condition in the suction channel 160.

Alternatively, the position detected by the detection sensor 170 may be the suction port 150, the entire suction passage 160, or a part of the suction passage 160 such as the communication passage 161. For example, the detection sensor 170 may be configured to detect a passing or remaining soil condition in the communication channel 161 and transmit the signal to the controller 180, such that the controller 180 determines whether the soil condition meets a predetermined condition. The detection sensor 170 is disposed outside the preset position, which is beneficial to preventing the stain from being blocked in the process of being sucked into the stain containing cavity 310 under the action of the suction assembly 320, and preventing the stain from polluting or damaging the detection sensor 170. Alternatively, the detection sensor 170 may be disposed inside the designated location. For example, the detection sensor 170 may be disposed outside the communication channel 161, corresponding to a preset position corresponding to a preset condition in the communication channel 161, for detecting whether the soil reaches the preset position in the communication channel 161, and transmitting the signal to the controller 180, so that the controller 180 correspondingly determines whether the soil condition reaches the preset condition. The preset position corresponding to the preset condition is a position where the detection sensor 170 detects the stain condition, for example, a position where infrared rays are used by the infrared pair tube sensor. The preset position can be a position where the stain is retained in the process of being sucked into the stain containing cavity 310 by the suction assembly 320, and the retained position refers to a position where the stain is accumulated to the preset condition. For example, the predetermined position may be set as a throat of the communication passage 161 between the main body case 110 and the cleaning case 120, and the detection sensor 170 is disposed outside the throat and corresponding to the throat of the communication passage 161 for detecting whether the remaining position of the dirt in the communication passage 161 has reached the throat position. When dirt is left in the communicating channel 161, dirt is accumulated continuously, the occupied space position extends downwards continuously until the throat position is reached, and the signal of the detection sensor 170 is weakened or disappears when the dirt is accumulated and reaches the throat. Therefore, whether the stain reaches the preset position can be judged by detecting the signal intensity change of the detection sensor 170, so as to judge whether the remained stain condition reaches the preset condition. The preset position may also be a position through which the soil passes during the process of being sucked into the soil accommodating chamber 310. For example, when the predetermined position is a throat, the detection sensor 170 is disposed outside the throat and corresponding to the inside of the throat of the communication passage 161 for detecting the contamination condition passing through the throat. When a small amount of stain passes through the throat, the signal of the detection sensor 170 is attenuated, but the amplitude of the attenuation is small. When a large amount of dirt passes through the throat, the signal of the detection sensor 170 is attenuated to a greater extent, and the signal received by the receiver in the detection sensor 170 is less intense. Therefore, the stain condition at the preset position can be judged by detecting the signal intensity detected by the detection sensor 170, so as to judge whether the passing stain condition reaches the preset condition.

Further, a controller 180 is provided in the housing 100. Alternatively, the controller 180 may be provided to the main machine housing 110 and/or the cleaning housing 120. For example, at least one controller 180 may be provided in the main body housing 110, at least one controller 180 may be provided in the cleaning housing 120, and at least one controller 180 may be provided in each of the main body housing 110 and the cleaning housing 120. As shown in fig. 5, the controller 180 is electrically connected to the detection sensor 170, the steam generating assembly 140 and the pumping assembly 320. The controller 180 may select different functions to be turned on according to various modes provided by different application scenarios. For example, the user may select a corresponding mode according to whether steam is required to be applied to the region to be cleaned, and the controller 180 may control the steam generation assembly 140 to be in an on state or an off state according to whether steam is required in the mode selected by the user, thereby controlling the steam function to be turned on or off. When the cleaning device 1 sucks the dirt, the detection sensor 170 detects the dirt condition and transmits a relevant signal related to the dirt condition to the controller 180, and the controller 180 can be used for receiving the relevant signal related to the dirt condition transmitted by the detection sensor 170, so as to judge whether the dirt condition detected by the detection sensor 170 reaches a preset condition. After the determination, the controller 180 may control the power of the pumping assembly 320 such that the pumping assembly 320 may use different powers in different application scenarios. For example, when a user wants to steam sterilize an area to be cleaned while using the cleaning apparatus 1, the steam mode of the cleaning apparatus 1 may be selected, and the controller 180 determines that steam needs to be turned on in the mode, and then controls the steam generation assembly 140 to be turned on to control the steam function to be turned on. When the steam function is turned on, the suction assembly 320 sucks the stain in the area to be cleaned, when the stain is sucked to the preset position, the detection sensor 170 starts to detect the stain condition at the preset position, transmits the detected related signal related to the stain condition to the controller 180, and the controller 180 judges the stain condition at the preset position and controls the operation power of the suction assembly 320 according to the judgment result.

Further, the controller 180 needs to receive the detection result signal of the detection sensor 170 to respond accordingly, so as to control the suction assembly 320. When the steam function is turned on, that is, during the steam output from the steam generating assembly 140, when it is determined that the soil condition detected by the detection sensor 170 does not reach the preset condition, the controller 180 controls the suction assembly 320 to operate at a first power lower than the preset power. The suction assembly 320 is controlled to operate at a first power lower than the preset power, and the steam generated by the steam generation assembly 140 is not sucked into the stain receiving cavity 310, thereby effectively recycling the stain and protecting the steam output. Before the soil condition does not reach the preset condition, the controller 180 may detect a level corresponding to the soil condition according to the soil condition detected by the detection sensor 170, and control the suction assembly 320 to operate at a first power value matching the level corresponding to the soil condition according to the detected level. By setting a plurality of levels and a plurality of first power values, the suction force of the suction assembly 320 can be adjusted according to the actual stain condition while the suction assembly 320 is kept in low-power operation, i.e. the steam output is protected to the maximum extent, so that the effective recovery of the stain can be realized. The controller 180 controls the suction assembly 320 to operate at the second power higher than or equal to the preset power when it determines that the soil condition detected by the detection sensor 170 reaches the preset condition. When the passing or remaining dirt condition reaches the preset condition, it indicates that the dirt condition of the area to be cleaned is more, and although the steam may be partially affected at this time, the power of the suction assembly 320 should be increased in a short time to increase the suction force, so as to achieve effective recycling of the dirt. And when the steam function is turned off, that is, when the steam generation assembly 140 is in an off state, the controller 180 serves to control the suction assembly 320 to operate at a third power higher than or equal to the preset power. When the steam is not generated, the suction assembly 320 should be controlled to be turned on with as high power as possible, so that the dirt can be quickly sucked into the dirt holding cavity 310, thereby effectively improving the cleaning efficiency. The operation power of the suction component 320 is controlled by the controller 180 according to the actual stain condition, so that the influence of the suction process on the output steam can be effectively reduced when the suction function and the steam function are simultaneously started, the output steam is protected while effective cleaning is guaranteed, the cleaning efficiency is improved, and meanwhile, the cleaning area can be effectively cleaned when only the suction function is started, and the cleaning efficiency is improved.

Alternatively, the controller 180 may be disposed in the cleaning housing 120, and an Inertial Measurement Unit (IMU) may be disposed in the controller 180, and the IMU may sense a state of the cleaning apparatus 1 such as forward, backward, or lifting. Through the IMU's perception of the motion state of the cleaning device 1, the controller 180 can predict the user's motion or needs, thereby improving the user's satisfaction.

The controller 180 may be used to execute a control method of the cleaning apparatus 1, for example, the controller 180 may store a corresponding computer program to execute the control method of the cleaning apparatus 1 when executing the computer program. As shown in fig. 6, the following describes an exemplary embodiment of a control method of the cleaning device in detail, mainly using the controller 180.

S100: during the steam generation assembly outputting steam, the detection sensor detects a passing or remaining stain condition in the suction channel.

The detection sensor 170 may detect a soil condition within the suction channel 160, i.e. the location where the soil condition is detected may be the suction channel 160. For example, the detection sensor 170 may be disposed outside the suction channel 160 to detect the passage or remaining of the dirt in the suction channel 160. Optionally, the detection sensor 170 can also detect the dirty condition passing through the suction opening 150, the dirty condition passing through the suction channel 160, and the dirty condition passing through both the suction opening 150 and the suction channel 160 according to the operation power of the suction assembly 320 and the dirty condition corresponding to the scene. Likewise, the detection sensor 170 can detect the presence of soil alone in the suction channel 160. Thus, the location to detect the soil condition may include the suction channel 160, the suction port 150, and the suction channel 160 and the suction port 150. For example, when the detection sensor 170 is disposed outside the suction port 150, the detection sensor 170 may detect and determine the dirt passing through the suction port 150. Alternatively, the number of the detection sensors 170 may be more than one, for example, two, one being disposed outside the suction port 150 and one being disposed outside the suction channel 160. The detection sensor 170 disposed outside the suction opening 150 can be used for detecting and judging the dirt passing through the suction opening 150; the detection sensor 170 disposed outside the suction channel 160 detects and determines the soil condition passing through the suction channel 160. The two detection sensors 170 can be used for more flexibly selecting the detection and judgment positions, and the stain condition can be further judged, so that a more accurate and reliable judgment result can be obtained.

Alternatively, the detection of the soil condition passing through the suction opening 150, the suction channel 160 and simultaneously the suction opening 150 and the suction channel 160 may be, for example, the detection of the amount of soil passing through the above-mentioned positions. This may include, for example, calculating the time required for the stain to pass over the location, such as the suction channel 160, for a certain length, or may include calculating the length of the stain to pass over the location, such as the suction channel 160, for a certain time. Optionally, a stain condition may also be detected within the dwell suction channel 160, for example the amount of stain remaining within the dwell suction channel 160 may be detected. For example, it may be possible to calculate the time required for the stain to fill the above-mentioned position where a certain volume is filled with the stain, for example, the suction passage 160, i.e., the retained stain, to reach a preset position, for example, the time required for the stain to accumulate to the throat position of the communication passage 161 when the stain is retained in the communication passage 161, and the amount of the stain to be 1 cubic decimeter/minute if the time required for accumulating to the volume occupied by the throat position is 0.001 cubic meter, for example. It may also include calculating the volume of the suction channel 160 that the stain occupies over time. Alternatively, the detection of the passing or remaining soil condition may not be an accurate value, and for example, it may be detected whether the soil reaches a predetermined position when the soil condition is accumulated to a certain degree. For example, when the stain detected by the detection sensor 170 reaches a predetermined position, a corresponding signal may be sent to the controller 180, and the controller 180 may determine the received signal.

S200: and judging whether the stain condition detected by the detection sensor reaches a preset condition or not.

After detecting the soil condition, the controller 180 determines whether the soil condition detected by the detection sensor 170 reaches a preset condition. The soil condition can include the amount of soil, which can be, for example, the volume of the soil, the mass of the soil, and the like. The preset condition is a threshold value of the passing or remaining soil condition, and may be a threshold value of the amount of soil, for example. And if the passing or remaining dirt condition exceeds the dirt condition threshold value, judging that the preset condition is reached. And if the passing or remaining dirt condition does not exceed the dirt condition threshold value, judging that the preset condition is not reached. For example, the passing or remaining stain amount threshold is 2 cubic decimeters per minute, and if the detected stain amount is 1 cubic decimeter per minute, the preset condition is judged to be not reached; and if the detected dirt amount is 2.1 cubic decimeters per minute, judging that the preset condition is reached. Alternatively, the soil condition threshold may not be an exact numerical value and may be a predetermined position. For example, when the detection sensor 170 is disposed outside the throat of the communication channel 161 and when the soil remains in the communication channel 161, if the throat is set to a preset position, that is, the throat is a soil condition threshold, the controller 180 determines that the remaining soil condition exceeds the soil condition threshold once the soil is accumulated to the throat position of the communication channel 161, that is, when the signal detected by the detection sensor 170 is in a stable attenuation state. The infrared signal of the detection sensor 170 is blocked due to the passing dirt, but is only temporarily blocked, and when the dirt is accumulated to the position, the signal can be regarded as being in a stable attenuation state, and at this time, it can be determined that the dirt condition exceeds the dirt condition threshold, that is, the preset condition is reached.

S300: the suction assembly is controlled to operate at a first power that is lower than the preset power.

During the steam output of the steam generating assembly 140, the controller 180 determines that the soil condition detected by the detection sensor 170 does not reach the preset condition, i.e., when the detected soil condition passing or remaining in the suction channel 160 does not reach the soil condition threshold, the controller 180 may control the suction assembly 400 to operate at a first power lower than the preset power. Since the preset power is higher power, the dirt cannot be remained in the suction channel 160 but is sucked into the dirt holding cavity 310 under the preset power, and part of the steam generated by the steam generating assembly 140 is sucked into the dirt holding cavity 310, so that the cleaning efficiency is reduced. The first power is lower than the preset power, and has little or no influence on the steam generated by the steam generating assembly 140, so that the dirt can be effectively recovered, and the steam output can be protected. Alternatively, at the first power, the stain is not sucked into the stain receiving chamber 310, but remains in the suction channel 160. Alternatively, the stain can be partially or completely sucked into the stain receiving chamber 310, but at this time the power is less and the steam generated by the steam generating assembly 140 is less or even not sucked. For example, the preset power may be 75% P, 80% P, 85% P, while the first power may be 10% P, 15% P, 20% power.

S400: the suction assembly is controlled to operate at a second power that is higher than or equal to the preset power.

When it is determined that the soil condition detected by the detection sensor 170 reaches the preset condition, the controller 180 controls the suction assembly 320 to operate at a second power higher than or equal to the preset power during the steam generation assembly 140 outputs the steam. The second power is higher than or equal to the preset power, e.g., the second power may be 85% P, 90% P, 100% P. At the second power, the suction assembly 320 increases the suction force on the stain so that the stain can be sucked from the suction channel 160 into the stain receiving chamber 310. When the passing or remaining dirt condition exceeds the threshold value, that is, the preset condition is reached, optionally, it may be considered that the suction channel 160 is full of dirt at this time, that is, the dirt cannot be loaded continuously, and it may also be considered that the dirt condition of the area to be cleaned is more at this time, so that the power of the suction assembly 320 should be increased to increase the suction force, thereby achieving effective recovery of the dirt. The time that the suction assembly 320 is operated at the second power is limited, and after the suction assembly 320 is operated at the second power for a period of time, that is, after all the soil in the suction channel 160 has been sucked into the soil accommodating chamber 310, the soil condition can be determined again.

The actual conditions during cleaning may vary, for example, the area to be cleaned may vary from a place with less soiling to a place with more soiling, for example, the area to be cleaned may have fewer soiling. Therefore, the method for the controller 180 to change the operation power of the suction assembly 320 by determining whether the soil condition detected by the detection sensor 170 reaches the predetermined condition is a continuous determination process, and may be changed according to the actual condition. By continuously varying the power of the suction assembly 320, the impact of the suction process on the output steam can be effectively reduced while the contaminants are effectively recovered.

Since the functions of the cleaning apparatus are separately and independently implemented, the user can select different modes of the cleaning apparatus 1 according to actual application scenarios. For example, when the steam function is not needed but only the cleaning of only some easily cleaned stains existing in the area to be cleaned is needed and the steam function is not needed, the cleaning apparatus 1 turns on the smart mode for the scene, and the controller 180 may control the steam generation assembly 140 to be in the off state at this time. When the area to be cleaned needs to be sterilized by high-temperature steam or stains which are difficult to clean exist, the cleaning device 1 starts a steam mode for the scene, and the controller 180 can control the steam generation assembly 140 to be in an on state. However, the control method shown in fig. 6 is applied to the process of outputting steam by the steam generating assembly 140, and therefore, before the method, it should be determined whether the steam generating assembly 140 is in the on state, as shown in fig. 7, reference may be specifically made to the following steps included before S100:

s110: and judging whether the steam generating assembly is in an opening state or not.

S120: if not, the suction assembly is controlled to operate at a third power higher than or equal to the preset power.

When it is determined that the steam generation assembly 140 is in the off state, the controller 180 controls the suction assembly 320 to operate at a third power higher than or equal to the preset power. Since the steam generating assembly 140 does not generate steam, the power of the pumping assembly 320 does not affect the steam. Therefore, the highest possible power should be turned on so that the dirt can be sucked into the dirt holding cavity 310 quickly, thereby effectively improving the cleaning efficiency. The third power should be higher than or equal to the preset power, e.g., 85% of the preset power, the third power may be 90% p, 100% p.

When it is determined that the steam generation assembly 140 is in the on state, the detection sensor 170 has not started to detect the soil condition. At this time, the controller 180 is configured to determine that the soil condition detected by the detection sensor 170 does not meet the preset condition during the steam generation assembly 140 outputting the steam and control the suction assembly 320 to operate at a first power lower than the preset power. Since the suction of the dirt is not started or is started just when the cleaning device 1 is switched on, the dirt situation is very small at this point, and the output of steam should be protected as much as possible, so the first power at this point should take a lower value, for example 15% p. After the cleaning device 1 has been in operation for a certain period of time, soil is already sucked into the cleaning device 1, at which point the detection of the soil condition by the detection sensor 170 is only activated.

Optionally, before the soil condition reaches the preset condition, the power of the suction assembly 320 may also be changed according to the soil condition, and specifically, the following steps included before S200 may be referred to:

s130: and judging the level corresponding to the stain condition.

Before the soil condition reaches the preset condition, the controller 180 can be configured to detect a corresponding level according to the soil condition detected by the detection sensor 170, and set different levels, such as a first level and a second level, according to different soil conditions, such as different amounts of soil, where the soil conditions corresponding to these levels are all less than the threshold value of the passed or retained soil condition. For example, where the soil condition is soil amount, when the threshold amount of soil passed or retained is 2 cubic decimeters per minute, the first level may correspond to a soil amount of 1 cubic decimeter per minute and the second level may correspond to a soil amount of 1.5 cubic decimeters per minute. A first rating may be determined when the amount of elapsed or remaining stain detected is greater than 1 cubic decimeter per minute and less than 1.5 cubic decimeters per minute. A second rating may be determined when the amount of elapsed or remaining stain detected is greater than 1.5 cubic decimeters per minute. Based on the determination of the level of soil condition by the controller 180, the controller 180 is configured to control the suction assembly 320 to operate at a first power level that matches the level corresponding to the soil condition.

S140: the suction assembly is controlled to operate at a first power level that matches a level corresponding to a soil condition.

Optionally, the first power may include a plurality of first power values at which the suction assembly 320 draws different levels of stain. The first power value is matched with the level corresponding to the soil condition. E.g., the first power is 15-p, when it is determined to be the first level, the suction assembly 320 is controlled to adjust the power to the first power value 20-p corresponding to the first level; when the second level is determined, the suction assembly 320 is controlled to adjust the power to the first power value 30% corresponding to the second level. By setting a plurality of first power values, the suction force of the suction assembly 320 can be adjusted according to the actual stain condition while the suction assembly 320 is kept in low-power operation, namely, the steam output is protected, so that the effective recovery of the stain can be realized.

Optionally, different levels can be correspondingly set according to different stain conditions treated in different modes. For example, the cleaning apparatus 1 may have a normal mode and a steam mode, in both of which the controller 180 controls the steam generation assembly 140 to output steam. However, the two modes are different from each other in the application scenario, wherein the steam mode is mainly to sterilize the area to be cleaned with high temperature steam, and there is not much stain, so that the suction assembly 320 is not required to operate at high power. If the steam mode is assigned to the first level, the soiling situation is lower, i.e. the first power value assigned to the first level should be lower. Whereas in the conventional mode, steam sterilization is only an adjunct role, when the area to be cleaned is primarily cleaned, the amount of soil is greater, requiring the suction assembly 320 to be operated at a slightly higher power. If the normal mode is assigned to the second level, the soiling situation is higher, i.e. the first power value assigned to the second level should be higher.

In summary, the stain condition passing or remaining in the suction opening 150/suction channel 160 of the cleaning device is detected by the detection sensor 170, so as to detect whether the currently sucked stain condition meets the preset condition. When the stain condition does not meet the preset condition, the controller 180 controls the suction assembly 320 to operate at a first power lower than the preset power, that is, the suction assembly can operate at a lower power, so that the stain can be sucked, meanwhile, the influence of the suction process of the suction assembly 320 on steam is reduced, and the amount of the steam sucked by the suction assembly 320 is reduced, thereby protecting the output steam, enabling more steam to be reserved in the area to be cleaned as much as possible, cleaning the area to be cleaned more effectively, and improving the cleaning efficiency.
