Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It will be apparent that the described embodiments are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by those skilled in the art based on the embodiments herein without making any inventive effort, are intended to be within the scope of the present application. In the following description and in the claims, the terms "include" and "comprise" are used in an open-ended fashion, and thus should be interpreted to mean "include, but not limited to. By "substantially" is meant that within an acceptable error range, a person skilled in the art is able to solve the technical problem within a certain error range, substantially achieving the technical effect. In addition, in the embodiments of the present application, plural means two or more. Those skilled in the art may combine and combine the features of the different embodiments or examples described in this specification and of the different embodiments or examples without contradiction.

After use (i.e. cleaning the surface to be cleaned) the cleaning assembly is cleaned with dirt. Many cleaning devices currently have a self-cleaning mode for convenience of use. The self-cleaning mode is that the cleaning device completes the autonomous cleaning process according to a program set in advance without human intervention. In the embodiments provided herein, cleaning devices include, but are not limited to, a hand-held floor washer, an intelligent drag-and-suction integrated robot, an intelligent floor washing system with a base station, and the like. On different cleaning devices, the cleaning member has different specific structures, for example, in some embodiments presented herein, when the cleaning device is a hand-held floor washer (as shown in fig. 1 a), the cleaning member is a cleaning rolling brush, and when the cleaning device is an intelligent drag-and-suction robot, the cleaning member is a cleaning wipe.

Fig. 1a shows a schematic structural diagram of a cleaning device according to an embodiment of the present application. As shown in fig. 1a, the cleaning device 1 may comprise: cleaning assembly 2, working assembly (not shown) and control means (not shown). Wherein the cleaning assembly 2 is adapted to be a self-cleaning object when the cleaning device is operating in a self-cleaning mode; when the cleaning device is operated in the external cleaning mode, the cleaning device is used as a cleaning execution body. If the "external cleaning mode" is understood as: a mode of cleaning a floor, a table top, a wall surface, a window, or the like outside the cleaning apparatus, then a "self-cleaning mode" is a mode of cleaning internal parts of the cleaning apparatus itself. For example, the cleaning assembly may include, but is not limited to: rag, roller brush, recycling line, recycling bin, etc. The working components may include, but are not limited to: a rolling brush driving device, a main motor generating suction force, a transfusion device outputting cleaning liquid, etc. The working assembly is used as a self-cleaning work load to clean the self-cleaning object when the cleaning equipment works in the self-cleaning mode, and is used as an external cleaning work load together with the cleaning execution body to clean the surface to be cleaned when the cleaning equipment works in the external cleaning mode. The control device is connected with the working assembly and used for controlling at least parts in the working assembly to work so as to enable the cleaning equipment to work in a self-cleaning mode or an external cleaning mode.

A cleaning apparatus of the construction shown in figure 1a, the cleaning apparatus comprising: a floor brush 3 and a machine body. The floor brush 3 is arranged on the machine body. The body may be provided with, but is not limited to: a water cleaning barrel 6, a recycling barrel 21, a recycling pipeline 22, etc. One end of the recovery pipeline 22 is communicated with the suction nozzle 4 on the floor brush 3, and the other end is communicated with the recovery barrel 21. The floor brush 3 is provided with a suction nozzle 4, and the suction nozzle 4 can suck dirt or dirty liquid on a surface to be cleaned (such as a floor, a table top, a carpet and the like) and enter the recovery barrel 21 through the recovery pipeline 22. The roller brush 23 on the floor brush 3 is rotatable to clean the surface to be cleaned. Thus, in the cleaning apparatus embodiment shown in FIG. 1a, the cleaning assembly may comprise: a roller brush 23, a recovery pipe 22, a recovery tank 21, and the like. Accordingly, the working assembly may include components not shown in the drawings: a driving device for driving the rolling brush to roll, a main motor for generating suction force, an infusion device for delivering cleaning liquid from the clean water bucket 6 to the rolling brush 23 and the surface to be cleaned, etc.

Specifically, when the cleaning device is in a self-cleaning mode, a cleaning liquid is output to form a liquid accumulation; generating a dynamically varying suction force such that the liquid product flows under the dynamically varying suction force to clean the self-cleaning object on the cleaning apparatus.

Further, when the cleaning device works in the self-cleaning mode, the control device of the cleaning device controls the infusion device to output the cleaning liquid to form the accumulated liquid, controls the main motor to generate dynamic suction force, and enables the accumulated liquid to flow under the action of the dynamic suction force so as to clean the self-cleaning object on the cleaning device.

The details of how the main motor is controlled to produce a dynamically varying suction force will be described in detail below, see corresponding below.

Further, the cleaning apparatus provided in this embodiment may further include a preparation device. Not shown in fig. 1a, the preparation device is used for preparing a sterilizing fluid. The prepared degerming liquid can be contained in the purified water bucket 6. For example, the preparation device may be an electrolyte preparation device.

Specifically, the electrolyte preparation device includes: a power supply circuit and an electrolysis electrode. The power supply circuit is electrically connected with the control device and used for being connected or disconnected under the control of the control device; and the electrolysis stage is electrically connected with the power supply circuit and arranged in the clean water tank of the cleaning equipment and is used for carrying set voltage when the power supply circuit is conducted so as to electrolyze liquid in the clean water tank and generate sterilizing liquid.

For example, when an electrolytic electrode having a certain voltage is placed in tap water, a certain amount of hypochlorous acid is generated by the electrolytic electrode because the tap water contains a certain chlorine element. In a specific embodiment, a certain amount of the sterilizing fluid is usually produced by placing an electrolysis electrode in a water tub containing a cleaning fluid (typically tap water or clear water containing a certain salt) and then electrolyzing the cleaning fluid. For the process of preparing the sterilizing liquid in the self-cleaning method, the sterilizing liquid can be prepared in advance before the self-cleaning process of the cleaning equipment starts, and the sterilizing liquid can also be prepared all the time in the whole self-cleaning process or in certain self-cleaning steps of the cleaning equipment.

Also, referring to fig. 1a, the roll brush 23 is accommodated in the roll brush chamber. The roller brush is stained with sewage and impurities when cleaning the surface to be cleaned, and because of the rotation of the roller brush, sewage points or small impurities may be splashed onto the cavity wall of the roller brush cavity. Under the self-cleaning mode of the cleaning equipment, the output cleaning liquid forming the effusion can have a certain depth, namely a large amount of effusion, so that a large amount of effusion can generate a relatively severe fluid flow effect under the action of dynamically-changing suction force, and the cavity wall of the rolling brush cavity can be cleaned along the belt while cleaning the rolling brush and the recovery channel.

In addition, the sterilizing liquid prepared by the preparation device in the embodiment can be used for self-cleaning of cleaning equipment, and can also be only used on self-cleaning objects (such as a rolling brush and a recycling channel) after self-cleaning, namely clean water in a clean water bucket is used for cleaning in the self-cleaning process, and the sterilizing liquid is sprayed on the self-cleaning objects for sterilization after the self-cleaning objects are cleaned.

In particular, the infusion device may be used to deliver a cleaning fluid (e.g., clear water, sterile fluid), such as a cleaning fluid infusion device to a self-cleaning subject. The cleaning liquid output by the infusion device may be clear water, cleaning liquid mixed with a degerming agent, degerming liquid obtained by electrolysis, or the like, which is not limited in this embodiment. Wherein the amount of liquid accumulation can be controlled by the control device. Typically the cleaning device is placed on a base when it is self-cleaning. The base is matched with the cleaning equipment, can be used when the cleaning equipment is self-cleaned, and has the functions of charging the cleaning equipment and the like. Assuming that the self-cleaning object comprises a roller brush, the liquid product may be partly absorbed by the roller brush, and partly remain on a base associated with the cleaning device, even in the chamber of the roller brush.

Further, the control device can also control the main motor to work so as to generate dynamic change suction force, so that the accumulated liquid flows under the action of the dynamic change suction force to wash the self-cleaning object. Specifically, the working power of the main motor can be adjusted through the control device so as to change the suction force, and the effect that the water flow continuously washes the recovery pipeline can be simulated.

Fig. 1b shows a schematic structural diagram of a cleaning system according to another embodiment of the present application. As shown in fig. 1b, the cleaning system comprises: cleaning device 1, preparation apparatus (not shown in the figures) and base 7. The cleaning device 1 can be placed on the base 7, and the preparation device is used for preparing the sterilizing liquid. Wherein the cleaning device comprises: cleaning assembly, work assembly and controlling means. A cleaning assembly for being a self-cleaning object when the cleaning apparatus is operated in a self-cleaning mode; when the cleaning device works in the external cleaning mode, the cleaning device is used as a cleaning execution body. The working assembly is used as a self-cleaning work load to clean the self-cleaning object when the cleaning equipment works in the self-cleaning mode, and is used as an external cleaning work load together with the cleaning execution body to clean the surface to be cleaned when the cleaning equipment works in the external cleaning mode. The control device is used for controlling the working assembly to work, the working assembly comprises an infusion device, and the infusion device is used for outputting the degerming liquid to form effusion under the control of the control device, so that the cleaning equipment can conveniently utilize the effusion to finish a self-cleaning task.

Further, the preparation device may be provided on the cleaning apparatus or on the base.

Specifically, the preparation device comprises: a power supply circuit and an electrolysis stage. The power supply circuit is electrically connected with the control device and used for being connected or disconnected under the control of the control device. The electrolysis stage is electrically connected to the power supply circuit and is arranged in the clean water bucket 6 of the cleaning device 1 or the water tank 72 on the base 7, and is used for carrying a set voltage when the power supply circuit is conducted so as to electrolyze the liquid in the clean water bucket and generate the sterilizing liquid.

In particular, after the cleaning device 1 is placed on the base 7, the cleaning device 1 can be in communication connection with the base in a wired or wireless manner, so that the control device on the cleaning device can send a control instruction to the power supply circuit arranged on the base 7.

Further, the base 7 is provided with a liquid accumulation area 71, and the liquid accumulation area 71 can accumulate a sterilizing liquid to soak and clean the self-cleaning object.

A self-cleaning method of the cleaning device will be described hereinafter by way of example of the method.

Fig. 2 is a schematic first flow chart of a self-cleaning method according to an embodiment of the present application, and referring to fig. 2, the self-cleaning method of a cleaning apparatus according to an embodiment of the present application is applicable to a control device of the cleaning apparatus, and the cleaning apparatus further includes: infusion set, main motor and at least one automatically cleaning object. The self-cleaning method comprises the following steps:

S101, controlling the infusion device to work so as to output cleaning liquid.

S102, controlling the main motor to work so as to generate dynamic change suction force, so that the cleaning liquid flows under the action of the dynamic change suction force, and the self-cleaning object on the cleaning equipment is cleaned.

In the above step S101, the cleaning liquid may be, but is not limited to: clear water, aqueous solutions with cleaning agents or sterile solutions produced electrolytically or otherwise. The cleaning liquid output can be output by a pump on the cleaning device or by opening a valve on the infusion line of the cleaning device.

In the step S102, the liquid pumped by the main motor may be the cleaning liquid output by the infusion device; or the infusion device outputs the cleaning liquid to the rolling brush and overflows the cleaning liquid from the rolling brush to the base; or after the infusion device wets the rolling brush, when the rolling brush is cleaned, the cleaning liquid accumulated on the effusion area after being scraped from the rolling brush. The liquid accumulation area can be positioned on a self-cleaning base matched with self-cleaning equipment or in a cavity of the self-cleaning equipment. The executing body that generates the dynamically changing suction force may be a main motor on the cleaning device. The main motor is capable of generating a suction force when in operation. The main motor may have at least two powers, such as low power, high power, etc., with varying magnitudes of suction force being generated by varying the switching of the main motor between the at least two powers. Alternatively, the gap suction force is generated by controlling the main motor to intermittently start and stop. Or, the fan in the main motor is controlled to switch between forward rotation and reverse rotation so as to generate variable acting force of suction and back blowing.

For example, in the implementation, the main motor is controlled to operate for a second with low power, then to operate for B seconds with high power, then to switch to operate for a second with low power, to operate for B seconds with high power, and so on, until a set period of time is reached or a set number of cycles is met, and so on. Wherein a may be greater than, equal to, or less than B, which is not limited in this embodiment. Similarly, for the intermittent start-stop scheme of the main motor, the main motor can be controlled to run for C seconds and stop for D seconds; and then running for C seconds and then for D seconds, and reciprocating in this way until the set duration is reached or the set number of cycles is met, and the like. C may be greater than, equal to, or less than D, and this embodiment is not limited thereto. In addition, for the forward and reverse rotation scheme, the fan in the main motor can be controlled to rotate forward for E seconds, then rotate reversely for F seconds, then rotate forward for E seconds, rotate reversely for F seconds, and reciprocate in this way until the set duration is reached or the set cycle times are met, and the like. Also, E may be greater than, equal to, or less than F, which is not limited in this embodiment.

The main motor is controlled to work in this way to generate dynamic suction force, under the action of the dynamic suction force, the accumulated liquid area reaches the recovery pipeline, and the cleaning liquid in the recovery pipeline can simulate the effect of continuous flushing of water flow, so that the self-cleaning effect can be effectively improved.

For example, the dynamic suction force generated by the positive and negative rotation scheme of the fan of the main motor, namely the back blowing force among the suction forces. For example, the suction force is generated just for a time when the cleaning solution flows from the suction nozzle of the cleaning device to the inlet of the recovery barrel or is close to the inlet and does not enter the recovery barrel, then the cleaning solution flows from the inlet of the recovery barrel or is close to the inlet to the suction nozzle reversely under the action of the back-blowing force, so that the cleaning solution is reciprocated, and the cleaning solution is flushed back and forth in the recovery pipeline to clean the recovery pipeline, and meanwhile, the back and forth flushing force also acts on the rolling brush at the suction nozzle to clean the rolling brush. When the cleaning liquid is more, the cleaning liquid stirred up by the rotating rolling brush can also clean the cavity wall of the rolling brush cavity.

In addition, in one embodiment provided in the present application, the step S101 may be performed simultaneously when the step S102 is performed, or the step S102 may be performed after the step S101 is finished, or the step S102 may be performed after a period of time after the step S101 is finished. According to the self-cleaning device and the self-cleaning method, the cleaning flow of the cleaning device is optimized, so that the cleaning liquid can clean the self-cleaning object under the action of the dynamically-changing suction force, and the self-cleaning effect of the cleaning device is effectively improved.

Self-cleaning objects in embodiments of the present application may include, but are not limited to: a rolling brush, rag, a recycling pipeline on cleaning equipment, a recycling bin and the like. In one possible embodiment, a rotary output device, such as a motor and a rotary output member (e.g., similar to a pulsator structure in a washing machine), may be provided in the recycling bin. The rotary output part is arranged in the recycling bin. When the cleaning equipment works in the self-cleaning mode, the control device of the cleaning equipment can send a control instruction to the motor, and the motor drives the rotary output part in the recycling bin to rotate after receiving the control instruction so as to stir sewage in the recycling bin to flow at a high speed, so that the wall of the recycling bin is cleaned.

In one embodiment provided herein, the self-cleaning object comprises a roller brush, and referring to fig. 3, controlling the operation of the infusion device to output the cleaning liquid comprises the steps of:

s103, a rolling brush infiltration stage: and controlling the infusion device to output cleaning liquid to the rolling brush so as to infiltrate the rolling brush.

S104, a liquid stopping rolling brush rotating stage: the infusion device is controlled to stop working, and the driving device is controlled to work so as to drive the rolling brush to rotate, so that attachments and liquid on the rolling brush can be scraped by the scraping device on the cleaning equipment to form effusion in the effusion area.

When a circulation requirement exists for the steps, the soaking stage and the rotation stage of the liquid stopping rolling brush are circulated according to the circulation requirement, and the steps S103 and S104 are completed in a circulation mode. The cycle requirements may be preconfigured, such as cycling once, twice or more, etc., and the present embodiment is not particularly limited thereto. In order to make the cleaning of the rolling brush cleaner and thoroughly, the cleaning device can circularly repeat the step S103 and the step S104 for a plurality of times, and the amount of accumulated liquid is increased along with the increase of the repetition times, so that the cleaning of other self-cleaning objects is more facilitated. By repeating the steps, more accumulated liquid can be accumulated, and the dirt concentration of the accumulated liquid can be reduced, so that the accumulated liquid is beneficial to cleaning other self-cleaning objects.

In the step S103, the rolling brush may absorb the cleaning solution, and after the rolling brush absorbs the cleaning solution, a part of the cleaning solution may be retained on the rolling brush, and the rolling brush may be soaked in the cleaning solution, and in the process of wetting the rolling brush, the attachments on the rolling brush may be wetted, so as to improve the cleaning effect on the attachments on the rolling brush.

Further, in step S104, after sufficient cleaning liquid is accumulated on the roller brush, the cleaning apparatus stops outputting the cleaning liquid to the roller brush, the roller brush rotates under the driving of the roller brush motor, and then the scraping device acting with the surface of the roller brush can scrape most of the cleaning liquid accumulated on the roller brush. In the process of scraping the cleaning liquid, dirt on the rolling brush is scraped clean along with the cleaning liquid, and the scraped attachment (dirt) and liquid are contained in the effusion area and enter the effusion. In particular, the liquid accumulation area may be an area on the base of the cleaning device, such as a recess or the like. In one embodiment provided by the application, the attachments and the cleaning liquid on the rolling brush can be combined with the centrifugal force action of the rolling brush to make the attachments and the cleaning liquid separate from the rolling brush more quickly and make the rolling brush cleaner.

In one embodiment provided in the present application, the self-cleaning object may further comprise a recycling line, see fig. 4, the self-cleaning method of the cleaning apparatus further comprising the steps of:

and S105, controlling the main motor to generate continuous suction force to suck the cleaning liquid, so that the flowing cleaning liquid flushes the recovery pipeline flowing through to the recovery barrel of the cleaning equipment.

And S106, controlling the output quantity of the cleaning liquid of the infusion device, and triggering the step of controlling the main motor to work so as to generate dynamic change suction force, so that the cleaning liquid flows under the action of the dynamic change suction force to clean the recovery pipeline.

In step S105, after the main motor generates the suction force, the cleaning liquid flows into the recovery tub of the cleaning apparatus along the recovery pipe by the suction force. Specifically, the recycling bin is a container on the cleaning device for storing waste water generated after cleaning. When the cleaning device is a hand-held floor washer, the recycling bin is mounted on the cleaning device. And when the cleaning device is an intelligent floor washing system with a base station, the recycling bin may be a recycling bin mounted on the base station. In addition, the recovery pipeline is a recovery pipeline communicated with the suction port of the cleaning equipment and the recovery barrel.

In one embodiment provided herein, the continuous suction force is generated to suck the cleaning liquid, so that the flowing cleaning liquid flushes the recovery pipe flowing through to the recovery tank of the cleaning device can be an intermittent process or a continuous process. For example, after enough cleaning liquid is accumulated on the self-cleaning base, the main motor provides the maximum suction force to continuously suck the cleaning liquid into the recovery barrel through the recovery pipeline, and a large amount of cleaning liquid flows into the recovery barrel at a high speed in the process of sucking the cleaning liquid into the recovery barrel, so that a large scouring force can be generated to scour dirt in the recovery pipeline. Alternatively, the main motor may be intermittently operated, for example, after a sufficient amount of cleaning liquid is accumulated in the cleaning liquid area, the main motor may provide a suction force to suck a portion of the cleaning liquid into the recovery tank through the recovery pipe, and then stop the operation for a while, and the cleaning liquid area may again provide a suction force after a sufficient amount of cleaning liquid is accumulated again, and suck the cleaning liquid into the recovery tank through the recovery pipe.

In step S106, the reduction of the output of the cleaning liquid may be controlled by controlling the infusion device, such as the power of the pump, the operation mode of the pump, or the operation time period. Alternatively, when the infusion device is a valve on an infusion line, the amount of output can be controlled by controlling the amount of opening of the valve. Wherein the output of cleaning liquid is reduced, and excessive water accumulated in the liquid accumulation area (a cleaning liquid accommodating area on a self-cleaning device or a self-cleaning base) can be prevented, so that the liquid accumulation area overflows. In the process that the cleaning solution flows under the action of the dynamically-changing suction force, only a small part of the cleaning solution is sucked into the sewage tank, and most of the cleaning solution is in the recovery pipeline and the effusion area, if the output of the cleaning solution is not reduced at the moment, the accumulation amount of the cleaning solution in the effusion area is increased along with the extension of the cleaning time, so that the effusion area is easy to overflow. In addition, a large amount of cleaning liquid is sucked into the recovery tank in the step S105, and in the step S106, in order to generate the effect of continuously flushing the simulated water flow, the main motor is controlled to generate dynamic suction force, and if the output quantity of the cleaning liquid is large, the flowing cleaning liquid is easy to splash, so that the surrounding environment is polluted. In one embodiment provided herein, the flowing cleaning liquid can also be indirectly caused to wash the roller brush or wipe during the cleaning of the recovery conduit with the cleaning liquid flowing. Because the cleaning liquid is initially accumulated in the liquid accumulation area, after the cleaning liquid in the liquid accumulation area is pumped to the recovery pipeline, the cleaning liquid can flow back to the liquid accumulation area in the back and forth cleaning process, and the cleaning liquid flowing back in the back and forth cleaning process can clean the rolling brush or the cleaning cloth.

In the examples provided herein, the creation of dynamically varying suction forces includes a variety of embodiments. Wherein, the power of the main motor can be controlled to be switched between at least two different powers, so that the main motor can generate different suction forces. For example, when it is desired to flow the cleaning liquid from below the recovery line to above the recovery line, the power of the main motor can be maximized and a maximum suction force can be generated, where the suction force of the main motor on the cleaning liquid is greater than the gravity force to which the cleaning liquid itself is subjected. When the cleaning liquid needs to flow from the upper part of the recovery pipeline to the lower part of the recovery pipeline, the power of the main motor can be reduced, so that the suction force generated by the main motor cannot overcome the gravity of the cleaning liquid, and the cleaning liquid can flow from the upper part of the recovery pipeline to the lower part of the recovery pipeline. And then the cleaning liquid can be cleaned back and forth on the recovery pipeline by circularly and reciprocally changing the power value of the main motor. Also, the cleaning of the roller brush or the rag can be achieved by first sucking the cleaning liquid to the uppermost part of the recovery pipe, then flushing the cleaning liquid from above the recovery pipe and impacting the roller brush or the rag, and the roller brush or the rag can be cleaned effectively by the process of circulating the cleaning liquid.

In addition, in one embodiment provided herein, the intermittent suction force can also be generated by controlling the intermittent start-stop of the main motor to generate a dynamically varying suction force. Alternatively, the fan in the main motor is controlled to switch between forward rotation and reverse rotation to generate suction and reverse blowing variable acting forces, so that the suction force is dynamically changed. In addition, a feasible scheme is also adopted, namely, the valve is used for controlling the main motor to generate dynamic change suction force, for example, an electric control valve is arranged at one end of a suction port of the main motor, and the air quantity sucked by the main motor can be controlled by controlling the size of an opening of the valve, so that the suction force of the main motor can be effectively controlled, and the suction force is dynamically changed.

In one embodiment provided herein, the cleaning apparatus further comprises a sterilizing liquid preparation device, and the self-cleaning method further comprises:

and controlling the working of the sterilizing liquid preparation device to prepare sterilizing liquid, and spraying the sterilizing liquid to the self-cleaning object after the sterilizing liquid is used as cleaning liquid or the self-cleaning object is finished.

The preparation process of the sterilizing liquid can be realized by putting the electrode with a certain voltage into tap water, and a certain amount of hypochlorous acid can be generated under the action of the electrode because the tap water contains a certain chlorine element. In a specific embodiment, a quantity of the sterilizing fluid is usually produced by placing an electrolysis electrode in a tank containing a cleaning fluid (typically tap water or clear water containing a certain salt) and then by electrolysis of the cleaning fluid. For the process of preparing the sterilizing liquid in the self-cleaning method, the sterilizing liquid can be prepared in advance before the self-cleaning process of the cleaning equipment starts, and the sterilizing liquid can also be prepared all the time in the whole self-cleaning process or in certain self-cleaning steps of the cleaning equipment.

Further, referring to fig. 5, the self-cleaning method provided in the embodiment of the present application further includes the following steps:

s107, after the self-cleaning object is cleaned, controlling the infusion device to stop outputting the cleaning liquid.

S108, controlling the cleaning device to generate a drying air flow so as to dry the self-cleaning object.

S109, controlling the infusion device to spray the sterilization liquid to the self-cleaning object.

In the above step S107, when the infusion device on the cleaning apparatus stops outputting the cleaning liquid, the preparation of the sterilizing liquid in the cleaning apparatus may be stopped or continued at this time. After the self-cleaning device is cleaned, the self-cleaning object is conveniently maintained later. The cleaning device will generate a drying air flow for drying the cleaning object. In particular, there are different drying methods for different self-cleaning objects, for example for a roller brush, which can be dried by a combination of the air flow disturbed by the rotation of the roller brush and the suction air flow generated by the main motor. The recovery duct can be dried by suction air flow generated by the main motor.

Further, in order to keep the self-cleaning object in a clean and sterile environment for a long time, in step S109, the self-cleaning apparatus is sprayed with the sterilizing liquid, and the sterilizing liquid is allowed to remain on the self-cleaning apparatus for a certain time, thereby achieving an antibacterial purpose. In addition, specifically, in order to make the sterilizing liquid have better sterilizing effect and sterilizing time, the sprayed sterilizing liquid has higher concentration, and the concentration of the sterilizing liquid can be increased by prolonging the preparation time of the sterilizing liquid. Or the user adds a certain medicament with a sterilization function to the sterilization liquid, so that the concentration of the sterilization liquid is increased.

In one embodiment provided herein, the self-cleaning method further comprises the steps of:

s110, detecting the cleanliness of the self-cleaning object, and if the cleanliness meets the set requirement, determining that the cleaning of the self-cleaning object is completed. Or alternatively

And S110', determining that the cleaning of the self-cleaning object is completed when the cleaning duration reaches the preset self-cleaning duration.

Specifically, a detection member may be provided on the self-cleaning object of the cleaning apparatus, and the detection member can accurately detect the cleanliness of the self-cleaning member. For example, at least one detection piece is respectively arranged on the rolling brush, the rolling brush cavity, the recovery pipeline and the recovery barrel.

In addition, step S110 can optimize the flow of the cleaning process of the cleaning apparatus. For example, in the process of executing each of the steps described above, such as steps S101 to S106, step S110 may be executed, i.e., the cleanliness of the self-cleaning object may be detected at any time during the self-cleaning process. When the detection piece detects that the cleanliness of the self-cleaning object meets the set requirement, the self-cleaning object is cleaned, and the next step is carried out. This shortens the period of time for self-cleaning, thereby making the self-cleaning process of the self-cleaning member more efficient and reducing unnecessary waste.

Or, if the self-cleaning duration reaches the preset self-cleaning duration, determining that the cleaning of the self-cleaning object is completed in step S110'. At this time, there are two cases, one is that the cleaning meets the requirement of cleanliness, and the other is that the cleaning is not. This scheme is long through setting up this default self-cleaning, is in order to avoid leading to the cleaning equipment to be in the condition of self-cleaning mode all the time because of some comparatively intractable stains.

Further, referring to fig. 6, in one embodiment provided herein, the self-cleaning method further comprises the steps of:

s111, monitoring the dirt degree of the self-cleaning object when the cleaning time reaches the first time.

And S112, if the dirt degree is larger than a first preset value, adjusting at least one of the output quantity of the cleaning liquid, a dynamic change strategy of suction force, a duration corresponding to the soaking stage of the rolling brush and a duration corresponding to the rotating stage of the liquid stopping rolling brush.

Wherein the first duration is less than a preset self-cleaning duration. In step S111 and step S112, at least one of the output of the cleaning liquid, the dynamic change strategy of the suction force, the duration corresponding to the soaking stage of the rolling brush, and the duration corresponding to the rotation stage of the liquid-stopping rolling brush is adjusted by detecting the dirt degree of the self-cleaning object according to the actual situation, so that the cleaning efficiency of the self-cleaning object can be effectively improved, and the cleaning time of the self-cleaning object and the consumed resources during cleaning can be reduced. Specifically, in the process of executing steps S101 to S106, the cleaning device may execute steps S111 and S112 before or simultaneously with any step, and reasonably adjust the amount of the cleaning liquid delivered to the roller brush by the infusion device, the dynamic change strategy of the suction force, the duration corresponding to the soaking stage of the roller brush, the duration corresponding to the rotation stage of the liquid stopping roller brush, and so on according to the dirt degree of the roller brush.

Further, referring to fig. 7, in one embodiment provided herein, the self-cleaning method further comprises the steps of:

s113, detecting the dirt degree of the self-cleaning object.

S114, acquiring the duration from the last self-cleaning end to the current moment of the self-cleaning object.

S115, determining self-cleaning parameters according to at least one of the dirt degree and the time duration.

Steps S113 to S115 may be operations before S101 in the present embodiment. In step S115, the self-cleaning parameters include: at least one of preparation amount of the sterilizing liquid, output amount of the sterilizing liquid, self-cleaning duration and dynamic change strategy of suction force. Specifically, for example, in the process of preparing the sterilizing liquid, the preparation amount of the sterilizing liquid can be determined according to the dirt degree of the self-cleaning object and the time period from the last time of the self-cleaning object to the current time, so that the self-cleaning object can have enough sterilizing liquid in the self-cleaning process, and the prepared sterilizing liquid can be used in time, thereby reducing unnecessary waste. For another example, in step S103, the amount of the cleaning liquid containing the degerming agent that the infusion device outputs to the rolling brush may be determined according to at least one of the dirt degree and the time period of the rolling brush, so that the cleaning of the rolling brush using the minimum amount of the cleaning liquid can be accomplished. In step S104, the rotational speed of the rolling brush may also be determined according to at least one of the dirt degree and the duration of the rolling brush, so as to save the electric quantity of the self-cleaning device and prolong the endurance of the self-cleaning device. In addition, in step S106, when the main motor of the cleaning apparatus outputs a dynamically changing suction force to clean the recovery pipe, a policy of dynamically changing the suction force may also be determined according to at least one of the dirt degree and the time period of the roller brush. When the dirt degree of the recovery pipeline is large, the suction force generated by the main motor can be controlled to adopt a powerful dynamic change strategy, and when the dirt degree or the time length of the recovery pipeline is short, the suction force generated by the main motor can be controlled to adopt a common dynamic change strategy.

In an embodiment provided in the present application, referring to fig. 8, there is also provided another self-cleaning method of a cleaning apparatus, suitable for a control device of the cleaning apparatus, the cleaning apparatus further comprising: infusion set, drive arrangement and round brush. The self-cleaning method comprises the following steps:

s201, a rolling brush infiltration stage: and controlling the infusion device to output cleaning liquid to the rolling brush so as to infiltrate the rolling brush.

S202, a liquid stopping rolling brush rotating stage: the infusion device is controlled to stop working, and the driving device is controlled to work so as to drive the rolling brush to rotate, so that attachments and liquid on the rolling brush can be scraped to a liquid accumulation area conveniently through the scraping device on the cleaning equipment.

For the above steps, when there is a circulation requirement, the circulation brush infiltration stage and the liquid-stopping brush rotation stage may be configured in advance according to the circulation requirement, and the circulation requirements of the circulation completion step S201 and the circulation completion step S202 may be configured in advance, for example, one circulation, two or more circulation steps, and the like, which is not limited in this embodiment. In order to clean the rolling brush more cleanly and thoroughly, the cleaning device can circularly repeat the step S201 and the step S202 for a plurality of times, and the accumulated cleaning liquid in the liquid accumulation area is increased along with the increase of the repetition times, so that the cleaning device is more beneficial to cleaning other self-cleaning objects. The steps are repeated, so that more cleaning liquid can be accumulated, the dirt concentration of the cleaning liquid can be reduced, and the cleaning liquid is beneficial to cleaning other self-cleaning objects.

In the step S201, the rolling brush may absorb the cleaning solution, and after absorbing the cleaning solution, the rolling brush may retain a part of the cleaning solution on the rolling brush, and infiltrate the rolling brush into the cleaning solution, and in the process of wetting the rolling brush, the adhering matter on the rolling brush may be wetted, so as to improve the cleaning effect on the adhering matter on the rolling brush.

Further, in step S202, after sufficient cleaning liquid is accumulated on the roller brush, the cleaning apparatus stops outputting the cleaning liquid to the roller brush, the roller brush rotates under the driving of the roller brush motor, and then the scraping device acting on the surface of the roller brush can scrape most of the cleaning liquid accumulated on the roller brush. In the process of scraping the cleaning liquid, the dirt on the rolling brush is scraped clean along with the cleaning liquid, and the scraped attachment (dirt) and the liquid are accommodated in the liquid accumulation area. In particular, the liquid accumulation area may be an area on a self-cleaning base of the cleaning device, such as a recess or the like. In one embodiment provided by the application, the attachments and the cleaning liquid on the rolling brush can be combined with the centrifugal force action of the rolling brush to make the attachments and the cleaning liquid separate from the rolling brush more quickly and make the rolling brush cleaner.

In one embodiment provided herein, referring to fig. 9, the self-cleaning method further comprises:

s203, detecting the dirt degree of the rolling brush.

S204, acquiring the time length from the last self-cleaning end to the current moment of the rolling brush.

S205, determining self-cleaning parameters according to at least one of the dirt degree and the duration.

Steps S203 to S205 may be operations before S201 in the present embodiment. In step S205, the self-cleaning parameters include: at least one of preparation amount of the sterilizing liquid, output amount of the sterilizing liquid, self-cleaning duration and dynamic change strategy of suction force. Specifically, for example, in the process of preparing the sterilizing liquid, the preparation amount of the sterilizing liquid can be determined according to the dirt degree of the self-cleaning object and the time period from the last time of the self-cleaning object to the current time, so that the self-cleaning object can have enough sterilizing liquid in the self-cleaning process, and the prepared sterilizing liquid can be used in time, thereby reducing unnecessary waste. For another example, the amount of cleaning liquid containing the degerming agent that the infusion device outputs to the roller brush may be determined according to at least one of the dirt degree and the time period of the roller brush, so that the roller brush can be cleaned with a minimum amount of cleaning liquid. In step S202, the rotational speed of the rolling brush may also be determined according to at least one of the dirt degree and the duration of the rolling brush, so as to save the electric quantity of the self-cleaning device and prolong the endurance of the self-cleaning device. In addition, when the main motor of the cleaning device outputs the dynamically-changing suction force to clean the recovery pipeline, the strategy of dynamically-changing suction force can also be determined according to at least one of the dirt degree and the time length of the rolling brush. When the dirt degree of the recovery pipeline is large, the suction force generated by the main motor can be controlled to adopt a powerful dynamic change strategy, and when the dirt degree or the time length of the recovery pipeline is short, the suction force generated by the main motor can be controlled to adopt a common dynamic change strategy.

In one embodiment provided herein, the cleaning apparatus further comprises a main motor, a recovery tank and a recovery pipe, see fig. 10, the self-cleaning method further comprising the steps of:

s206, controlling the infusion device to output cleaning liquid, controlling the main motor to work and controlling the driving device to work so as to drive the rolling brush to rotate, so that accumulated liquid in the accumulated liquid area is sucked into the recovery barrel, and the recovery pipeline is cleaned.

S207, controlling the output quantity of the cleaning solution of the infusion device, and maintaining the working states of the main motor and the driving device so as to continuously clean the recovery pipeline.

In step S206, the driving device works and drives the rolling brush to rotate, so that the rolling brush continuously completes self-cleaning, the rolling brush generates accumulated liquid in the self-cleaning process, the accumulated liquid is accommodated in the accumulated liquid accommodating area, when the infusion device continuously outputs cleaning liquid, the accumulated liquid is more and more in quantity, under the action of the suction force generated by the main motor, the accumulated liquid is sucked into the recycling bin, and when the accumulated liquid flows from the accumulated liquid area to the recycling bin, the flowing accumulated liquid can flush the pipeline. In step 207, by controlling the amount of the cleaning liquid output of the infusion device, the utilization rate of the cleaning liquid can be improved, and in particular, the specific amount of the cleaning liquid output can be adjusted according to the degree of contamination of the roller brush, which can be achieved by performing steps S203 to S205. In addition, the amount of the cleaning solution can be saved by adjusting the output amount of the cleaning solution, for example, after the rolling brush is cleaned, the recovery pipeline is preliminarily cleaned, and the cleaning solution for cleaning the recovery pipeline is the sewage scraped from the rolling brush before, so that a certain amount of sewage can remain on the recovery pipeline when the recovery pipeline is flushed, and the sewage is cleaned without much water, so that the recovery pipeline is flushed cleanly through a small amount of cleaning solution by controlling the output amount of the cleaning solution.

Further, the self-cleaning method further comprises:

and controlling the main motor to generate dynamic suction force, so that the cleaning liquid flows under the action of the dynamic suction force, and simulating water flow to clean the recovery pipeline.

In order to make the flushing effect on the recovery pipeline better, the cleaning solution is flowed by dynamic suction force, and the recovery pipeline is flushed. Specifically, when the recovery pipeline is cleaned, the main motor provides the maximum suction force at first, the cleaning solution is sucked to the tail end (one end close to the recovery barrel) of the recovery pipeline, then the main motor reduces the suction force, the cleaning solution can flow back to the bottom end of the recovery pipeline from the tail end of the recovery pipeline, and the suction force generated by the main motor is in a dynamic change process through circulation for a plurality of times, so that the cleaning solution can wash the recovery pipeline back and forth.

The main body of execution of each step in the above embodiment is a cleaning apparatus. The following embodiments provide a self-cleaning method of a cleaning apparatus, which performs a control device of a main body, in particular, a cleaning apparatus. In addition, the cleaning apparatus further includes: infusion set, main motor and automatically cleaning object. The self-cleaning method of the cleaning device comprises the following steps:

s301, controlling the infusion device to work so as to output the sterilizing liquid.

S302, controlling the main motor to work so as to generate dynamic change suction force, so that the cleaning liquid flows under the action of the dynamic change suction force, and the self-cleaning object is cleaned.

When the cleaning device is positioned on the self-cleaning base, the cleaning liquid firstly output wets the cleaning elements (rags or the rolling brush), and when the rolling brush is self-cleaning, the cleaning liquid on the rolling brush is scraped off to form accumulated liquid. Or the output cleaning liquid wets the cleaning element after absorbing the maximum water quantity, and the surplus water can accumulate in the cavity of the self-cleaning base or the accommodating cavity of the cleaning equipment. At this time, the cleaning liquid scraped off by the rolling brush and the cleaning liquid accumulated on the cleaning member, in the cavity of the self-cleaning base or in the accommodating cavity of the cleaning device are equivalent to accumulated liquid. Then, by changing the suction force of the main motor, the suction force is dynamically changed, the accumulated liquid flows under the action of the dynamically changed suction force, the flowing direction is continuously changed along with the dynamically changed suction force, and the self-cleaning object can be cleaned in the flowing process.

Further, when the self-cleaning object comprises a roller brush, the cleaning device further comprises a driving means. Correspondingly, the step S301 "controlling the infusion device to work so as to output the sterilizing liquid" includes the following steps:

In the above steps, when a circulation requirement exists, the soaking stage of the rolling brush and the rotation stage of the liquid stopping rolling brush are circulated according to the circulation requirement.

Under specific use conditions, firstly, the cleaning equipment enters a self-cleaning mode, the control device responds to a control signal of the self-cleaning mode, the control device controls the infusion device to work and conveys the sterilizing liquid to the rolling brush, at the moment, the rolling brush is wetted, after the rolling brush is wetted, the control device controls the infusion device to stop working, and controls the driving device to work so as to drive the rolling brush to rotate, so that attachments and liquid on the rolling brush can be scraped by the scraping device on the cleaning equipment to a liquid accumulation area to form liquid accumulation. And then the control device controls the main motor to work so as to generate dynamic change suction force, so that the accumulated liquid flows under the action of the dynamic change suction force, and the self-cleaning object is cleaned. Specifically, the liquid accumulation formed in the liquid accumulation area may be formed by scraping the degerming liquid on the rolling brush by the scraping device after the rolling brush is immersed, or may be formed by scraping the degerming liquid flowing out of the rolling brush and the degerming liquid on the rolling brush together by the scraping device when the rolling brush is immersed. When the effusion is flowed under the action of the dynamically-changing suction force to clean the self-cleaning object, the self-cleaning object can be one object or a plurality of objects, for example, one object can be a recovery pipeline, and a plurality of objects can be rolling brushes and recovery pipelines.

Further, in one embodiment provided herein, the self-cleaning object further comprises a recycling conduit. Correspondingly, the method provided by the embodiment may further include the following steps:

s305, controlling the main motor to generate continuous suction force to suck the effusion, so that the flowing effusion flushes the recovery pipeline flowing through to the recovery barrel of the cleaning equipment;

s306, controlling the liquid quantity of the infusion device, and triggering the step of controlling the main motor to work so as to generate dynamic change suction force, so that the accumulated liquid flows under the action of the dynamic change suction force to clean the recovery pipeline.

In the above steps, controlling the operation of the main motor to produce a dynamically varying suction force may be controlled by: 1. the main motor is controlled to switch between at least two powers to produce a suction force of varying magnitude. 2. The main motor is controlled to intermittently start and stop to generate intermittent suction force. 3. The fan in the main motor is controlled to switch between forward rotation and reverse rotation to generate suction and back blowing variable acting force.

Further, the cleaning apparatus further includes: a device for preparing the degerming liquid. The self-cleaning method of the cleaning device further comprises the step of controlling the working of the sterilizing liquid preparation device by the controller so as to prepare the sterilizing liquid. The sterilizing fluid preparation apparatus may prepare the sterilizing fluid in various ways, and in one embodiment, the sterilizing fluid may be generated by disposing an electrode in the cleaning fluid and then electrolyzing the cleaning fluid. Or the degerming liquid preparation agent is contained in the degerming liquid preparation device, and is continuously released into the cleaning liquid by the degerming liquid preparation device, so that the degerming agent is prepared by the cleaning equipment.

For the above steps, when there is a circulation requirement, the circulation brush infiltration stage and the liquid-stopping brush rotation stage may be configured in advance according to the circulation requirement, and the circulation requirements of the circulation completion step S401 and the circulation completion step S402 may be configured in advance, for example, one circulation, two or more circulation steps, and the like, which is not limited in this embodiment. In order to clean the rolling brush more cleanly and thoroughly, the cleaning device can circularly repeat the step S401 and the step S402 for a plurality of times, and the accumulated cleaning liquid in the liquid accumulation area is increased along with the increase of the repetition times, so that the cleaning device is more beneficial to cleaning other self-cleaning objects. The steps are repeated, so that more cleaning liquid can be accumulated, the dirt concentration of the cleaning liquid can be reduced, and the cleaning liquid is beneficial to cleaning other self-cleaning objects.

Further, referring to fig. 12, in one embodiment provided herein, the cleaning apparatus further includes a main motor, a recovery tank, and a recovery pipe, and the self-cleaning method further includes the steps of:

s403, cleaning a recovery pipeline: after the liquid stopping rolling brush rotating stage, controlling the infusion device to output cleaning liquid, controlling the main motor to work and controlling the driving device to work so as to suck the accumulated liquid in the accumulated liquid area into the recycling bin.

S404, a rolling brush dehydration stage: and controlling the infusion device to stop working, and continuously working the main motor and the driving device to dehydrate the rolling brush.

In the step S403, the infusion device outputs a cleaning solution for wetting the rolling brush or forming a liquid pool, where the liquid pool is a liquid contained in the liquid pool area. The main motor works to generate suction force, the driving device drives the rolling brush to rotate so as to clean the rolling brush, the suction force generated by the main motor sucks the accumulated liquid in the accumulated liquid area into the recycling bin, and the accumulated liquid cleans the recycling pipeline in the process of being sucked into the recycling bin.

In step S404, the driving device drives the rolling brush to rotate so as to dehydrate the rolling brush, and simultaneously, the main motor works to generate a suction force to suck the accumulated liquid in the accumulated liquid area or the cleaning liquid scraped by the rolling brush to the recycling bin.

and (3) a rolling brush dehydration recovery stage: and after the liquid stopping rolling brush rotating stage, controlling the main motor and the driving device to work so as to dehydrate the rolling brush and recycle accumulated liquid to the recycling bin through the recycling pipeline.

Further, in one embodiment provided in the present application, before the roll brush infiltration stage, the self-cleaning method further comprises the steps of:

The preparation stage of the degerming liquid: and controlling the operation of the sterilizing liquid preparation device to generate the sterilizing liquid.

Wherein the apparatus for preparing a sterilizing liquid remains in operation in a stage subsequent to the stage of preparing the sterilizing liquid. After the preparation stage of the sterilizing liquid, the sterilizing liquid preparation device can prepare the sterilizing liquid at a stable speed in the whole self-cleaning process of the cleaning equipment, and can also prepare the sterilizing liquid at different speeds in different stages or processes. For example, the sterilizing fluid preparation apparatus is operated at full power and at a maximum speed during a roll brush soaking stage, and is operated at a general power and at a medium speed during a cleaning recovery pipe stage.

Further, in one embodiment provided herein, the self-cleaning method further comprises the steps of:

s405, detecting the dirt degree of the rolling brush.

S406, determining self-cleaning parameters according to the dirt degree.

Wherein the self-cleaning parameters include at least one of: the output quantity of the cleaning liquid, the working time of the infusion device, the rotating speed of the rolling brush, and the circulation times of the soaking stage of the rolling brush and the rotating stage of the liquid stopping rolling brush. Specifically, for example, in the process of preparing the sterilizing liquid, the preparation amount of the sterilizing liquid can be determined according to the dirt degree of the self-cleaning object and the time period from the last time of the self-cleaning object to the current time, so that the self-cleaning object can have enough sterilizing liquid in the self-cleaning process, and the prepared sterilizing liquid can be used in time, thereby reducing unnecessary waste. In one embodiment provided herein, the self-cleaning process is roughly divided into four phases: preparing a sterilizing liquid, soaking by a rolling brush, cleaning a recovery pipeline and dehydrating by the rolling brush. Specific cleaning procedures can be referred to in the following table.

In the above table, the roller brush soak includes two steps, which can be cycled back and forth multiple times until the roller brush is cleaned. In addition, "preparation of a sterile liquid" in the table means that the sterile liquid preparation apparatus prepares a sterile liquid, which may be obtained by means of an electrolytic cleaning liquid in one specific embodiment. Wherein the cleaning liquid can be common clear water or clear water containing sodium chloride. In the preparation process of the sterilizing liquid, whether the sterilizing liquid preparation device is started or not is determined, and various technical schemes exist in the embodiment provided by the application, wherein the first technical scheme is that after a cleaning device starts a self-cleaning process, the sterilizing liquid preparation device starts to prepare the sterilizing liquid, after the sterilizing liquid reaches a certain amount, other self-cleaning steps are started, and in the subsequent self-cleaning steps, the sterilizing preparation device is always started. The second technical scheme is that after the cleaning equipment starts a self-cleaning process, firstly the sterilizing liquid preparation device starts to prepare sterilizing liquid, and after the sterilizing liquid reaches a certain amount, the sterilizing liquid preparation device is closed, and then other self-cleaning steps are started. The third technical scheme is that the demand of the sterilizing liquid is determined by detecting the dirt degree of the rolling brush, and then whether the sterilizing liquid preparation device is started or not is determined by combining the demand of the sterilizing liquid and the preset cleaning time in the self-cleaning process. For example, in a self-cleaning process, a self-cleaning device detects the dirt degree of a rolling brush, and the required amount of the sterilizing liquid is predetermined, so that the time for preparing the sterilizing liquid is also determined, then a sterilizing liquid preparation device is started in a sterilizing liquid preparation stage and a rolling brush soaking stage, and the sterilizing liquid preparation device is closed in a cleaning recovery pipeline and a rolling brush dewatering stage.

After the self-cleaning process is started, firstly, preparing a sterilizing liquid: the main motor in the cleaning equipment is closed, the rolling brush motor is closed, the infusion device is closed, the sterilizing liquid preparation device is opened, and the period lasts for 30 seconds, so that the amount of the sterilizing liquid meets the use requirement.

Then, the rolling brush soaking comprises two stages, namely a rolling brush soaking stage (A1) and a liquid stopping rolling brush rotating stage (A2). The main motor in the cleaning equipment is closed in the soaking stage of the rolling brush, sewage cannot be pumped, the infusion device conveys the sterilizing liquid to the rolling brush, the rolling brush motor stops rotating, and the sterilizing liquid preparation device is started at the moment. The rolling brush has certain water absorption, so that the sterilizing liquid can be retained on the rolling brush and the rolling brush is soaked. In the rotation stage of the liquid stopping rolling brush, the main motor stops rotating, the rolling brush motor rotates and drives the rolling brush to rotate together, and the transfusion device is closed, so that cleaning liquid on the rolling brush is scraped clean.

Subsequently, the recovery line is cleaned: the main motor is started, and the suction force of the main motor is in a dynamic change state. So that the liquid accumulation is cleaned back and forth on the recovery pipeline. The rolling brush motor is started to clean accumulated liquid on the rolling brush, in addition, the infusion device and the sterilizing liquid preparation device are also in an opened state, and the output quantity and the output time of the infusion device can be adjusted according to the dirt degree of the rolling brush detected by the detection piece.

Finally, dewatering by a rolling brush: the main motor is started to suck all accumulated liquid completely, the rolling brush motor is started to clean the accumulated liquid on the rolling brush, the infusion device stops working, and the sterilizing liquid preparation device is still started to prepare enough sterilizing liquid.

The differences for the different self-cleaning modes of operation of the cleaning apparatus may comprise at least one of the following: the cleaning time of the self-cleaning object, the dehydration time of the self-cleaning object, the flow rate of the infusion device of the cleaning device, the power of the main motor of the cleaning device and the rotating speed of the rolling brush of the cleaning device.

When the self-cleaning object is a roller brush and a suction channel, the cleaning time of the roller brush and/or the suction channel may be different for different self-cleaning modes, and the dewatering time of the roller brush and/or the suction channel may be different.

In combination with the above-mentioned self-cleaning process of the self-cleaning apparatus, in a further embodiment provided in the present application, the end of the self-cleaning process of the self-cleaning apparatus further comprises a sterilization maintenance phase. See the table below for specific procedures.

In the above table, in the cleaning stage of the cleaning recovery pipe, the infusion device may be opened or closed, which may be set according to a specific practical situation, when the dirt level of the recovery pipe is high, the infusion device may be opened at this time to provide sufficient sterilizing liquid to clean the recovery pipe, and when the dirt level of the recovery pipe is low, the infusion device may be closed at this time to save the sterilizing liquid.

In the final sterilization maintenance stage, the main motor is closed, the rolling brush motor is closed, the infusion device is opened to convey the sterilization liquid to the rolling brush, and the sterilization liquid preparation device is opened. In this stage, only a short period of time, for example, 3 seconds, 5 seconds, etc., is sustained, thereby effectively preventing the infusion device from outputting more sterilization liquid and enabling the self-cleaning base to generate effusion.

In summary, according to the technical scheme provided by the embodiment of the application, through optimizing the cleaning flow of the cleaning device, the cleaning liquid is output to form the effusion, and then the dynamically-changing suction force is generated, so that the effusion flows under the action of the dynamically-changing suction force, and the self-cleaning object on the cleaning device is cleaned, so that the self-cleaning effect of the cleaning device is effectively improved.

In order to facilitate understanding of the technical scheme of the application, a specific application scenario is given below to describe in detail a self-cleaning method of the cleaning device provided by the application.

Application scenario one:

after the cleaning device works for a period of time, the user considers that the cleaning device is dirty, and the user manually triggers a self-cleaning control on the cleaning device according to the dirt degree of the cleaning device. Cleaning equipment is started, and sterilizing liquid is prepared firstly, and then the next stage or the process of preparing and using is carried out after the preparation amount of the sterilizing liquid reaches the requirement. After entering the next stage, the infusion device outputs the sterilizing liquid to infiltrate the rolling brush, and liquid accumulation is formed at the rolling brush. And then stopping outputting the sterilizing liquid, starting the rolling brush motor, rotating the rolling brush, and rapidly scraping dirt on the rolling brush by using a scraping device on the rolling brush. The two stages of outputting the sterilizing liquid and stopping outputting the rotation of the rolling brush can be circulated for a plurality of times. After meeting the circulation requirement, the main motor of the cleaning equipment is started, the rolling brush motor is started, the infusion device is started (outputting the sterilizing liquid), a large amount of accumulated liquid is rapidly sucked into the recovery barrel, and a large amount of accumulated liquid rapidly passes through the recovery pipeline, so that the dirt in the recovery pipeline can be washed cleanly. And then, reducing the output quantity of the degerming liquid, and continuously flushing the recovery pipeline with small water quantity by using the main motor to maintain the current working state to suck accumulated liquid. Of course, the control device can also control the main motor to generate dynamic suction force so as to simulate the effect that water flow continuously washes the cleaning pipeline.

Application scene two

In the self-cleaning process of the cleaning equipment, the dirt degree inside the cleaning equipment is continuously detected, when the self-cleaning is carried out for a period of time (first preset time), the detected dirt degree does not meet the requirement, the cleaning effect is poor, the cleaning equipment adjusts the relevant operation parameters of the self-cleaning, and the self-cleaning is continued to the cleaning equipment according to the adjusted relevant operation parameters.
