The water amount in the cleaning tank 21 is set to be at least in contact with the bristles of the cleaning roller 11, so that the cleaning roller 11 can receive the cleaning liquid sprayed by the water supply device 12 and can also be in contact with the cleaning liquid accumulated in the cleaning tank 21, the cleaning liquid can immerse the bristles on the cleaning roller 11, the bristles on the cleaning roller 11 are subjected to double infiltration and cleaning, and the infiltration efficiency and the self-cleaning effect of the cleaning roller 11 are improved;
step S3-soil pick-up stage: the surface cleaning machine 1 starts the dirt suction motor 13, so that the dirt suction motor 13 can drive the dirt suction device 14 to suck dirty liquid on the cleaning roller 11 and the cleaning tank 21, the sucked dirty liquid can enter the dirt containing barrel 15 through the dirt suction port 141 and the dirt suction pipeline 142 in sequence, the dirt containing barrel 15 can collect the dirty liquid conveniently, a user can clean the dirty liquid conveniently in a centralized manner, and the working rotating speed of the dirt suction motor 13 is V1; wherein the rated working speed V1 of the dirt suction motor 13 is set to 70000 rpm.
It will be understood by those skilled in the art that by providing the step S1-surface cleaning stage in the self-cleaning method of the surface cleaning machine 1 and setting the step S1-surface cleaning stage as turning on the water supply device 12, the water supply device 12 can spray or mist the cleaning roller 11 or the cleaning tank 21 so that the water supply device 12 consumes a small amount of cleaning liquid to wet the surface of the bristles on the cleaning roller 11, so that the surface cleaning machine 1 can rinse the cleaning roller 11 while wetting, and the excess cleaning liquid flows into the cleaning tank 21. In addition, in the process, the cleaning liquid attached to the surface of the bristles of the cleaning roller can still flow into the cleaning tank, so that the bristles on the cleaning roller 11 can be further soaked in the subsequent step S2-soaking deep cleaning stage.
The step S2-immersion deep cleaning stage is arranged after the step S1-surface cleaning stage, the step S2-immersion deep cleaning stage is set to be that the cleaning roller 11 is driven to rotate by the rolling brush motor, the water supply device 12 continues to spray or atomize the cleaning roller 11 or the cleaning groove 21, so that the cleaning roller 11 with the surfaces of the bristles fully absorbing water in the step S1-surface cleaning stage can be further immersed by the cleaning liquid, the whole bristles and the roots can fully absorb water, the whole bristles can be fully cleaned under the immersion condition, layered cleaning of the bristles on the cleaning roller 11 is achieved, and the cleaning effect of the whole cleaning roller 11 is ensured to be more thorough. Especially, after the cleaning roller 11 is not cleaned for a long time or the cleaning roller 11 cleans dirty ground, more or dry stains are easily adhered to the bristles, and the bristles are sufficiently soaked to separate the stains from the bristles, so that the stains can be conveniently sucked away in the subsequent step S3, i.e., the stain sucking stage.
The step S3-dirt absorbing stage is arranged after the step S2-soaking deep cleaning stage, and the dirt absorbing stage is set to be started up to the dirt absorbing motor 13, so that the dirt absorbing device 14 can absorb the dirt liquid on the cleaning roller 11 and the cleaning tank 21 to the dirt containing barrel 15 through the dirt absorbing opening 141 and the dirt absorbing pipeline 142, the residue of the dirt liquid in the cleaning roller 11 and the cleaning tank 21 is reduced, the cleaning roller 11 and the cleaning tank 21 are convenient to dry, and the phenomenon of long-time damp and mildewing is prevented. In addition, because the water consumption of the cleaning roller 11 in the step S1-surface cleaning stage and the step S2-immersion deep cleaning stage is sufficient, when the step S3-soil suction stage is performed, a large amount of cleaning liquid can enter the soil containing barrel 15 from the soil suction port 141 and the soil suction pipeline 142, so as to flush the soil suction pipeline 142, and ensure that the soil suction pipeline 142 can be cleaned without leaving dirt.

As another preferable implementation, in step S1 — the surface cleaning stage, the roll brush motor is activated to rotate the cleaning roller 11 while the water jet is spraying.
As can be understood by those skilled in the art, the roller brush motor is started while the water jet sprays liquid, so that the outer surface of the cleaning roller 11 can be uniformly sprayed by the water jet, the surfaces of the bristles on the cleaning roller 11 can be uniformly wetted, and the sanitary dead corners which cannot be sprayed on the cleaning roller 11 are avoided.
As a preferred implementation manner of the present embodiment, in step S1-surface cleaning phase, the water supply device 12 supplies water to the cleaning roller 11 at a flow value Q1, and the water supply time is set to T1 seconds; during step S2, the water supply device 12 supplies water to the cleaning roller 11 at a flow rate Q2, Q2 < 0.5Q1, and the water supply time is T2, T2 > 2T 1. Preferably, Q2 is 0.4Q1, T1 is set to 10s, and T2 is set to 25 s.
For example, if the surface cleaning machine 1 is set to 130ml/min in step S1-flow value Q1 in the surface cleaning phase, then correspondingly, the flow value Q2 in step S2-immersion depth cleaning phase is set to a form of less than 65ml/min, such as 60ml/min, 55ml/min, and so on.
It can be understood by those skilled in the art that by setting the flow value of the water supply device 12 at the step S1-the surface cleaning stage to Q1, the flow value of the water supply device 12 at the step S2-the infiltrating deep cleaning stage to Q2, and Q2 < 0.5Q1, the surface cleaning machine 1 can quickly fill the water supply channel and the water spray opening when the step S1 is performed, so that the bristles can be quickly wetted with a large flow rate Q1 and a small total amount of water for relatively deep cleaning, and when the step S2-the infiltrating deep cleaning stage is performed, the water supply device 12 can continuously supply water to the cleaning roller 11 at a small flow rate Q2, so that the water supply device 12 can maintain water uniformly supplied to the water spray opening for a long time, so that the bristles can be sufficiently infiltrated and then repeatedly cleaned, so that self-cleaning of the bristles of the cleaning roller 11 from a shallow depth is more thorough, the efficiency is high, and the water in the water tank can be prevented from being quickly used up, the trouble that the user frequently adds water to the water supply device 12 is also avoided; meanwhile, the total water amount of the whole cleaning process is not too much, the work of the sewage suction motor 13 and the containing burden of the sewage containing barrel 15 in the step S3-sewage suction stage in the later stage are reduced, the full collecting speed of the sewage containing barrel 15 is reduced, a user does not need to frequently clean the sewage containing barrel 15, the self-cleaning effect and the self-cleaning efficiency of the surface cleaning machine 1 are ensured, and the use experience of the user is improved.
In summary, the step S1-surface cleaning stage is provided to enable the water supply device 12 to spray or spray the liquid into the cleaning roller 11 or the cleaning tank 21, so that the surface cleaning machine 1 can wet the surface of the bristles on the cleaning roller 11, thereby facilitating the further wetting and cleaning of the bristles on the cleaning roller 11 in the subsequent step S2-deep wetting cleaning stage. By providing the step S2-soaking deep cleaning stage after the step S1-surface cleaning stage, the water supply device 12 continues to spray or mist the cleaning roller 11 and the cleaning tank 21 while the roller brush motor drives the cleaning roller 11 to rotate, so that the cleaning roller 11 with the surface of the bristles fully soaked with water in the step S1-surface cleaning stage can be further soaked by the cleaning liquid, the whole body and the roots of the bristles can also fully absorb water, layered cleaning of the bristles is realized, and the dirt washed from the bristles flows into the cleaning liquid in the cleaning tank 21, and is conveniently sucked by the dirt sucking device 14 in the step S3-dirt sucking stage. By arranging the step S3-dirt absorbing stage after the step S2-soaking deep cleaning stage, the dirt absorbing device 14 can absorb the dirt liquid in the cleaning roller 11 and the cleaning tank 21, so as to prevent the cleaning roller 11 from getting damp and mildewing and realize the flushing of the dirt absorbing pipeline 142.
Example two: as shown in FIG. 5, compared with the first embodiment, the self-cleaning method of the surface cleaning machine 1 in the present embodiment further includes a step S4-spin-drying stage disposed after the step S3-soil pick-up stage.
That is, the surface cleaning machine 1 in the present embodiment is capable of acquiring a self-cleaning signal, initiating a self-cleaning mode, wherein the self-cleaning mode comprises the following sub-steps:
step S1-surface cleaning stage: the surface cleaning machine 1 starts the water supply device 12, the cleaning liquid in the water supply device 12 can flow through the water supply channel at the first flow value Q1 and spray the cleaning liquid into the cleaning roller 11 or the cleaning groove 21 through the water spray opening, so that part of the cleaning liquid is accumulated in the cleaning groove 21, and the cleaning liquid sprayed by the water supply device 12 can at least wet and clean the bristles on the surface of the cleaning roller 11;
step S2-immersion deep cleaning stage: the rolling brush motor works and drives the cleaning roller 11 to rotate, the water supply device 12 sprays water into the cleaning roller 11 or the cleaning groove 21 in a rotating state through the water spraying opening at a second flow value Q2, the cleaning liquid can carry out secondary wetting on the cleaning roller 11, meanwhile, the water quantity accumulated in the cleaning groove is at least one third of the cleaning roller submerged until the cleaning liquid wets all bristles on the surface of the cleaning roller 11 and completely cleans the bristles, wherein Q2 is 0.45Q 1. And the water quantity in the cleaning tank 21 is set to be at least one third of the form of immersing the cleaning roller 11, so that the bristles on the cleaning roller 11 can be completely immersed into the cleaning liquid in the cleaning tank 21, the self-cleaning effect of the root parts of the bristles on the cleaning roller 11 is improved, and the phenomenon that the root parts of the bristles cannot be effectively cleaned is avoided.
Step S3-soil pick-up stage: the surface cleaning machine 1 starts the dirt suction motor 13, so that the dirt suction motor 13 can drive the dirt suction device 14 to suck dirty liquid on the cleaning roller 11 and the cleaning tank 21, the sucked dirty liquid can enter the dirt containing barrel 15 through the dirt suction port 141 and the dirt suction pipeline 142 in sequence, the dirt containing barrel 15 can collect the dirty liquid conveniently, a user can clean the dirty liquid conveniently in a centralized manner, and the working rotating speed of the dirt suction motor 13 is V1;
step S4-spin-dry stage: the water supply device 12 is closed, the dirt suction motor 13 is kept in an open state to drive the dirt suction device 14 to continuously provide suction, the roller brush motor is kept in an open state to drive the cleaning roller 11 to continuously rotate, and the dirt suction device 14 sucks dirty liquid flowing through the cleaning roller 11 into the dirt containing barrel 15 through the dirt suction port 141 and the dirt suction pipeline 142 for storage; the suction time is set to T3 to improve the cleaning and drying effect of the cleaning roller 11; the dirt suction motor 13 is operated at a speed of V2, V2 > V1 to ensure that the dirt suction device 14 can provide sufficient suction to the scrub roller 11.
It can be understood by those skilled in the art that since the step S2 of soaking deep cleaning is provided in the previous self-cleaning process, and the subsequent process passes through the step S3 of dirt-absorbing, there may still be a situation where the suction is not completely sucked on the cleaning roller 11, resulting in liquid residue on the cleaning roller 11 or the cleaning roller 11 being wet. Therefore, by providing the step S4-spin-drying stage after the step S3-soil pick-up stage and setting the step S4-spin-drying stage to the water supply device 12 being off, the soil pick-up motor 13 is kept in an on state so that the soil pick-up device 14 can suck the soil liquid flowing through the cleaning roller 11 into the soil containing tub 15, and the cleaning roller 11 is kept in a rotating state, and the suction time of the soil pick-up motor 13 is set to T3. The soil pick-up motor 13 provides suction to the soil pick-up device 14, so that the soil pick-up device 14 can suck residual soil liquid in the cleaning roller 11 and the cleaning tank 21 through the soil pick-up pipeline 142, so as to accelerate the drying speed of the cleaning roller 11, the cleaning tank 21 and the soil pick-up pipeline 142 and shorten the self-cleaning time of the surface cleaning machine 1.
And, by setting the cleaning roller 11 to be kept in a rotating state and setting the operating speed of the dirt suction motor 13 to be V2, V2 > V1, the dirt suction device 14 sucks the entire outer peripheral surface of the cleaning roller 11 with a stronger suction force during the step S4-spin-drying stage; in addition, the rotating cleaning roller 11 can throw out the water stain attached to the surface of the brush hair by the centrifugal force, and the water stain is pumped away by matching with the dirt suction motor 13, so that the self-cleaning effect of the cleaning roller 11 in the step S4-spin-drying stage is further improved. Preferably, V2 is set at 75000 rpm.
It should be noted that, when the surface cleaning machine 1 in the present invention enters the step S3-soil pick-up stage, the opening time of the soil pick-up motor 13 is not specifically limited, and any one of the following embodiments may be adopted:
as a preferred implementation, the soil pick-up motor 13 is momentarily activated when the surface cleaning machine 1 is entering the soil pick-up stage of step S3.
It can be understood by those skilled in the art that the cleaning roller 11 in the step S3-dirt suction stage is kept rotating, so that the cleaning roller 11 can throw away the water stain on the surface by centrifugal force to cooperate with the dirt suction motor 13 to suck the water stain into the dirt holding barrel 15. In addition, the dirt suction motor 13 is set to be started instantly, so that the dirt suction motor 13 can suck the cleaning roller 11 and the cleaning tank 21 when entering the step S3-dirt suction stage, the dirt suction time of the dirt suction device 14 is prolonged, the dirt suction effect of the dirt suction device 14 on the cleaning roller 11 and the cleaning tank 21 is improved, and dirt residue is avoided.
As another preferred implementation, when the surface cleaning machine 1 enters the step S3, the dirt suction stage, the roller brush motor drives the cleaning roller 11 to rotate for a period of time, and then the dirt suction motor 13 is started.
It can be understood by those skilled in the art that by setting the step S3-soil pick-up stage to a mode in which the roller brush motor can drive the cleaning roller 11 to rotate continuously for a period of time before the soil pick-up motor 13 is started, the cleaning roller 11 can also flush and clean the bristles in the cleaning liquid in the cleaning tank 21 after entering the step S3-soil pick-up stage, so as to prolong the cleaning time of the cleaning roller 11 and improve the self-cleaning effect of the bristles on the cleaning roller 11. And then the dirt suction motor 13 is started, so that the dirt suction motor 13 can suck the cleaned cleaning roller 11 and the cleaning groove 21, and the dirt is prevented from remaining.
As a preferred implementation manner of the present embodiment, in step S1, the surface cleaning stage, the water supply device 12 supplies water with a flow value Q1; in step S2, the wetting deep cleaning stage, the water supply device 12 supplies water at a flow rate Q2, and Q2 is 0.45Q 1.
It can be understood by those skilled in the art that, compared with the first embodiment, by setting the flow value Q2 to be 0.45Q1, and slightly larger than the value of Q2 in the first embodiment, the water supply device 12 can supply more cleaning liquid to the cleaning roller 11 to improve the self-cleaning effect of the cleaning roller 11 while taking into account the water supply time, and more cleaning liquid accumulated in the cleaning tank 21 can be pumped into the dirt holding barrel 15 by the following steps S3-dirt suction stage and S4-spin-drying stage, without worrying about the phenomenon that the sewage is too much and can not be pumped out completely.
In summary, in the embodiment, the step S3-the dirt suction stage can primarily suck away the sewage in the cleaning roller 11 and the cleaning tank 21, and the step S4-the spin-drying stage, which is arranged after the step S3-the dirt suction stage, can continuously suck the cleaning roller 11 to further suck away the water stains remaining on the cleaning roller 11 and the cleaning tank 21, so that the self-cleaning effect of the cleaning roller 11 is improved, the drying speed of the cleaning roller 11 can be increased by the action of the wind field, and the time required by the cleaning roller 11 to be wetted, mildewed, bred with bacteria and compressed for the self-cleaning of the surface cleaning machine 1 is avoided.
Example three: as shown in fig. 6, compared with the second embodiment, the self-cleaning method of the surface cleaning machine 1 in the present embodiment further includes a process of determining whether the cleaning roller 11 is cleaned or not, which is provided between the step S3-soil pick-up stage and the step S4-spin-drying stage.

step S1-surface cleaning stage: the surface cleaning machine 1 starts the water supply device 12, the cleaning liquid in the water supply device 12 can flow through the water supply channel at a first flow value Q1 and spray into the cleaning roller 11 or the cleaning groove 21 through the water spray opening, so that part of the cleaning liquid is accumulated in the cleaning groove 21, and the cleaning liquid sprayed by the water supply device 12 can at least wet and clean the bristles on the surface of the cleaning roller 11;
step S2-immersion deep cleaning stage: the rolling brush motor works and drives the cleaning roller 11 to rotate, the water supply device 12 continues to spray into the cleaning roller 11 or the cleaning tank 21 in a rotating state through a water spraying opening at a second flow value Q2, wherein Q2 is 0.3Q1, and the cleaning liquid completely wets and cleans bristles on the surface of the cleaning roller 11;
step S3-soil pick-up stage: the surface cleaning machine 1 starts the dirt suction motor 13, so that the dirt suction motor 13 can drive the dirt suction device 14 to suck dirty liquid on the cleaning roller 11 and the cleaning tank 21, the sucked dirty liquid can enter the dirt containing barrel 15 through the dirt suction port 141 and the dirt suction pipeline 142 in sequence, the dirt containing barrel 15 can collect the dirty liquid conveniently, a user can clean the dirty liquid conveniently in a centralized manner, and the working rotating speed of the dirt suction motor 13 is V1;
judging whether the cleaning roller 11 is clean: if the surface cleaning machine 1 judges that the cleaning roller 11 is not cleaned, the surface cleaning machine 1 enters the circulation of the step S2-the soaking deep cleaning stage and the step S3-the dirt absorbing stage again, and the circulation frequency is N; if the surface cleaning machine 1 judges that the cleaning roller 11 is cleaned, the step S4-spin-drying stage is directly carried out;
step S4-spin-dry stage: the water supply device 12 is closed, the dirt suction motor 13 is kept in an open state to drive the dirt suction device 14 to continuously provide suction, the roller brush motor is kept in an open state to drive the cleaning roller 11 to continuously rotate, and the dirt suction device 14 sucks dirty liquid flowing through the cleaning roller 11 into the dirt containing barrel 15 through the dirt suction port 141 and the dirt suction pipeline 142 for storage; the suction time is set to T3 to improve the cleaning and drying effect of the cleaning roller 11; the dirt suction motor 13 is operated at a speed of V2, V2 > V1 to ensure that the dirt suction device 14 can provide sufficient suction to the scrub roller 11.
As will be understood by those skilled in the art, by providing the process of determining whether the cleaning roller 11 is cleanly cleaned, when the cleaning roller 11 is determined not to be cleanly cleaned, the surface cleaning machine 1 re-enters the loop process of step S2-the soaking deep cleaning phase and step S3-the soil pick-up phase, the number of loops being N, until the cleaning roller 11 is determined to be cleanly cleaned; when the cleaning roller 11 is determined to be cleaned, the process proceeds to step S4, which is a spin-drying stage. By setting the process of judging whether the cleaning roller 11 is clean, it can be ensured that the cleaning roller 11 is sufficiently cleaned. In addition, in the process that the cleaning roller 11 repeatedly enters the dirt suction stage of the step S2, the wetting deep cleaning stage and the step S3, the dirt suction pipeline 142 can be sufficiently flushed, so that the dirt suction pipeline 142 can be kept in a relatively clean state, and the phenomenon that dirt is accumulated in the dirt suction pipeline 142 is avoided.

By setting Q2 to a small value, the surface cleaning machine 1 can reduce the water consumption of the surface cleaning machine 1 to the maximum when the step S2-the soaking deep cleaning phase and the step S3-the dirt suction phase are cyclically executed.
In summary, in the present embodiment, the process of determining whether the cleaning roller 11 is clean is provided between the step S3-soil pick-up stage and the step S4-spin-drying stage, so that the clean cleaning roller 11 after the step S3-soil pick-up stage can enter the next step for spin-drying, and the cleaning roller 11 which is not completely cleaned is circulated through the step S2-soaking deep cleaning stage and the step S3-soil pick-up stage until the cleaning roller 11 is completely cleaned, thereby ensuring the self-cleaning effect of the surface cleaning machine 1.
