The self-cleaning method of the present application is further described below with reference to the accompanying drawings.

The first embodiment of the present application:

as shown in fig. 1 to 4, the surface cleaning system of the present embodiment includes a surface cleaning apparatus 1 and a cleaning assembly 2, and the surface cleaning apparatus 1 includes a cleaning head 11, a body 12, a cleaning roller 13 as a wiping member, and a dirt collection box 14. Wherein the body 12 is pivotally connected to the cleaning head 11, the body 12 having a handle for gripping by a user, the user being able to control the travel of the surface cleaning apparatus 1 by holding the handle. The two cleaning rollers 13 are respectively arranged at the front end and the rear end of the cleaning head 11, the cleaning rollers 13 are in pivot connection with the cleaning head 11, the surface cleaning device 1 is provided with a driving motor for driving the cleaning rollers 13 to rotate, and the rotating cleaning rollers 13 can clean the surface to be cleaned. Two scraping pieces 111 are arranged on the cleaning head 11, and the two scraping pieces 111 respectively correspond to the two cleaning rollers 13 so as to scrape and squeeze the two cleaning rollers 13. The dirty liquid that is scraped and extruded by scraping piece 111 can fall into in the middle of the dirty box 14 that collects, and dirty box 14 that collects is equipped with two drainage 141 with two cleaning roller 13 laminating respectively to prevent that dirty liquid from outflowing.

The cleaning roller 13 may be scraped directly by the drain 141 of the dirt collection box 14 without the scraper 111.

With continued reference to fig. 1 to 4, further, the dirt collection box 14 is provided with a dirt discharge outlet 142 and a valve 143, and an elastic member (e.g., a torsion spring, a tension spring, a spring leaf, etc.) is provided between the valve 143 and the dirt collection box 14, and the elastic member is used for keeping the valve 143 at a position for closing the dirt discharge outlet 142. The cleaning assembly 2 is provided with a cleaning tank 21, a dirt collecting cavity 22, a driving part 23 and a pedal 24, the driving part 23 is a top column, after the surface cleaning device 1 is placed on the cleaning assembly 2, the two cleaning rollers 13 are respectively accommodated in the two cleaning tanks 21, a scraping rib (not shown in the figure) for contacting with the cleaning rollers 13 is arranged in the cleaning tank 21, the driving part 23 supports against a valve 143, and therefore the elastic force of the elastic component is overcome to open the sewage outlet 142, and the dirt collecting box 14 and the dirt collecting cavity 22 are communicated through the sewage outlet 142. The cleaning roller 13 rotates for cleaning in the cleaning tank 21, and the scraping piece 111 scrapes the liquid flow generated by the cleaning roller 13 into the dirt collecting box 14 and enters the dirt collecting cavity 22 from the dirt discharge outlet 142. A communication hole (not shown) and a sealing member (not shown) for closing the communication hole are provided between the wash tank 21 and the soil collection chamber 22, and when the pedal 24 is depressed, the sealing member opens the communication hole and the wash tank 21 communicates with the soil collection chamber 22. The surface cleaning apparatus 1 or the cleaning module 2 is provided with a sound generating device (not shown in the figure) for generating an alarm sound.

Referring to fig. 5, the cleaning method of the present embodiment includes:

butt joint: the surface cleaning apparatus and the cleaning assembly are docked in position so that the cleaning roller is positioned within the cleaning tank.

Specifically, the user places the surface cleaning apparatus 1 on the cleaning assembly 2 with the cleaning roller 13 in place in the cleaning tank 21 to contact the cleaning solution in the cleaning tank 21.

In particular, after the surface cleaning apparatus 1 is placed on the wash assembly 2, the drive portion 23 abuts the valve 143 such that the valve 143 opens the waste outlet 142.

It should be noted that an electric valve may also be disposed in the dirt collecting box 14, and the opening and closing of the electric valve is controlled by the control module.

A cleaning step: so that the cleaning roller rotates and cleans in the cleaning tank.

Specifically, the cleaning roller 13 is rotated by the driving motor, wherein the cleaning roller 13 on the front side of the cleaning head 11 is rotated counterclockwise (as indicated by a dotted arrow in fig. 3 and 4), and the cleaning roller 13 on the rear side of the cleaning head 11 is rotated clockwise (as indicated by a dotted arrow in fig. 3 and 4).

Further, in the present step, the rotation speed of the cleaning roller 13 is switched from the lower first rotation speed N1 to the higher second rotation speed N2, in which:

as an example one: referring to fig. 6, the voltage of the driving motor is changed in a stepwise manner, so that the cleaning roller 13 rotates from a first low rotation speed N1 to a second high rotation speed N2, specifically, the voltage of the driving motor is maintained at a voltage value at which the cleaning roller 13 rotates at the first rotation speed N1, and after the voltage of the driving motor is maintained for a while, the voltage of the driving motor is raised to another voltage value, and the voltage is maintained for a while, so that the rotation speed of the cleaning roller 13 is raised until the voltage of the driving motor is maintained at a voltage value at which the cleaning roller 13 rotates at the second rotation speed N2, so that the cleaning roller 13 keeps rotating at the second rotation speed N2. During this period, the scraping member 111 scrapes the cleaning roller 13, can extrude the liquid that the cleaning roller 13 absorbed, and keep off the rivers that the cleaning roller 13 drove, as shown by the solid line arrow in fig. 4, when the rotational speed of cleaning roller 13 is lower, the liquid stream that is scraped and extruded and keeps off back is far away from drain 142 at the drop point of collection dirty box 14, as shown by the solid line arrow in fig. 5, when the rotational speed of cleaning roller 13 is faster, the liquid stream that is scraped and extruded and kept off back directly falls at the drop point of collection dirty box 14 and is nearer from drain 142.

It should be noted that the voltage for driving the motor may be varied in a uniform stepwise manner, or in a non-uniform stepwise manner, such as by making a lower voltage last longer or making a higher voltage last longer. In other words, the duration of each rotational speed may be different during the variation.

As example two: referring to fig. 7, the voltage of the driving motor is continuously varied to rotate the cleaning roller 13 from the first low rotation speed N1 to the second high rotation speed N2, and specifically, the voltage of the driving motor is maintained at a voltage value for rotating the cleaning roller 13 at the first rotation speed N1, and after a certain period of time, the voltage of the driving motor is continuously increased until the voltage of the driving motor is maintained at a voltage value for rotating the cleaning roller 13 at the second rotation speed N2, so that the cleaning roller 13 is rotated at the second rotation speed N2.

It should be noted that the image of the rising or falling voltage portion may be a constant slope or a slope-changing image, for example, the image of the low voltage portion is made more moderate or the image of the high voltage portion is made more moderate.

A prompting step: and enabling the sound generating device to work, and reducing the rotating speed of the cleaning roller to a preset rotating speed n, wherein the preset rotating speed n is less than any rotating speed in the cleaning step.

Specifically, after the scrub roller 13 is scrubbed for a certain time, the user is required to press the pedal 24 to discharge the wastewater in the scrubbing tank 21 into the wastewater collection chamber 22, so the generating device is operated to remind the user, and the rotation speed of the scrub roller 13 is reduced to a preset rotation speed N, which is less than any rotation speed in the scrubbing step, that is, the preset rotation speed N is less than the first rotation speed N1 in the scrubbing step.

It should be noted that the sound generating device may be a buzzer or a voice prompt element.

As can be understood by those skilled in the art, the self-cleaning method of the embodiment ensures the cleaning effect of the cleaning roller 13 by reducing the rotation speed of the cleaning roller 13 to the preset rotation speed n when the generating device is in operation and making the preset rotation speed n less than the rotation speed in the cleaning step, and when the sounding device is in operation, the rotation speed of the cleaning roller 13 is reduced, so that the sound generated by the cleaning roller 13 due to the rotation in the cleaning tank 21 is reduced, the sound generated by the rotation of the cleaning roller 13 is prevented from covering the alarm sound of the sounding device, so that the user far away from the cleaning assembly 2 or in other rooms can hear the alarm sound more clearly, and on the basis of ensuring the cleaning effect of the cleaning roller 13, the user can receive information in time to discharge the sewage in the cleaning tank 21 to the sewage collecting cavity 22, so as to facilitate the drying operation of the cleaning roller 13, the cleaning roller 13 is prevented from being placed in a wet state, the cleaning roller is convenient for a user to use next time, and the user experience is improved.

Further, by switching the cleaning roller 13 from the lower first rotation speed N1 to the higher second rotation speed N2 in the cleaning step, the cleaning roller 13 can be cleaned at a low rotation speed to wash off the dirt attached to the surface of the cleaning roller 13, and then cleaned at a high rotation speed to ensure the cleaning effect of the cleaning roller 13, so as to avoid that the dirt attached to the surface of the cleaning roller 13 is thrown out of the cleaning assembly 2 by the cleaning roller 13 after the cleaning at the high rotation speed is adopted at the beginning on the premise of ensuring the cleaning effect. In addition, in the cleaning process of the cleaning roller 13, the cleaning roller 13 which is rotated by the scraping piece 111 in a scraping mode can extrude the liquid absorbed by the cleaning roller 13 to fall into the dirt collecting box 14, and because the cleaning roller 13 is increased from the lower first rotating speed N1 to the second rotating speed N2, the falling point of the liquid flow extruded by the scraping piece 111 in the dirt collecting box 14 is changed, so that different areas of the dirt collecting box 14 are cleaned, the cleaning roller 13 can realize self-cleaning in the cleaning groove 21, meanwhile, the self-cleaning of the dirt collecting box 14 is realized, the cleaning work of a user is reduced, and the user experience is improved.

The self-cleaning method of the present embodiment is exemplified below:

the first rotating speed N1 is 150 revolutions per minute, the second rotating speed N2 is 400 revolutions per minute, in the cleaning step, the cleaning roller 13 rotates at 150 revolutions per minute for 40 seconds, then the cleaning roller is lifted to 260 revolutions per minute for 40 seconds, then the cleaning roller is lifted to 400 revolutions per minute for 40 seconds, so that the switching from the first rotating speed N1 to the second rotating speed N2 is completed, after the cleaning roller 13 rotates at 400 revolutions per minute for 40 seconds, the sounding device works to give out a warning sound, and at the moment, the rotating speed of the cleaning roller 13 is reduced to 50 revolutions per minute.

In this embodiment, the preset rotation speed N is preferably equal to one third of the first rotation speed N1, so that the difference between the preset rotation speed N and the rotation speed in the cleaning step is large enough to make the sound of the sound generating device be better highlighted. In addition, the cleaning roller 13 is still operated at a low rotating speed when the generating device works, firstly, the cleaning roller 13 is prevented from stopping, so that the rotating sound of the cleaning roller 13 is not covered by the sound generating device, the cleaning roller 13 can keep rotating, the rotating speed of the cleaning roller 13 is conveniently increased again, the pollution discharge after self-cleaning is convenient, and the self-cleaning effect and efficiency are not influenced.

It should be noted that the preset rotation speed N may be less than 1/2 of the first rotation speed N1 and greater than 1/4.

In this embodiment, it is preferable that the preset rotation speed n is greater than 0, in other words, the rotation speed of the cleaning roller 13 is reduced, but the rotation is not stopped, that is, the rotation is maintained at a lower rotation speed, so that the cleaning roller 13 can maintain the rotation on the basis that the rotation sound of the cleaning roller 13 does not cover the sound of the sound generating device, and the rotation speed of the cleaning roller 13 is increased again.

It should be noted that the cleaning roller 13 may also stop rotating in the prompting step, that is, the preset rotation speed n is 0.

As an example of the washing step, in the washing step, the cleaning roller 13 stops rotating at set time t1, and restarts after the stop time t2 has elapsed. In other words, the driving motor is stopped at set time t1, and then the cleaning roller 13 is stopped, and after time t2 elapses, the driving motor is restarted to rotate the cleaning roller 13 again.

As can be understood by those skilled in the art, by stopping the cleaning roller 13 at intervals of the set time t1, on one hand, the cleaning liquid in the cleaning tank can impact the cleaning roller 13 when the cleaning roller 13 stops, so as to improve the washing effect of the cleaning liquid on the cleaning roller 13, and at the same time, the cleaning liquid impacts the cleaning roller 13, so that the fluff of the cleaning roller 13 is spread, so as to improve the cleaning effect on the inner layer of the fluff, thereby contributing to improving the cleaning effect of the cleaning roller 13, and on the other hand, in the case that the cleaning roller 13 stops for a period of time, the dirt in the cleaning liquid can be settled, and when the cleaning roller 13 rotates again, the cleaning liquid contacting with the cleaning roller 13 is cleaner.

Specifically, time t1 may be 5 seconds, 10 seconds, 20 seconds, etc., which may be selected by the user as desired. Preferably, time t2 is less than 5 seconds, such as 2 seconds, 3.5 seconds, etc., to avoid unduly lengthening the cleaning time of scrub roller 13.

As an example of the cleaning step, during the cleaning process of the cleaning roller 13, the rotation speed of the cleaning roller 13 is increased and decreased, that is, the rotation speed of the cleaning roller 13 is changed from the first rotation speed N1 to the second rotation speed N2, and not all the way up, so that the water flow is disturbed, and the cleaning effect of the water flow on the cleaning roller 13 is improved.

Specifically, unlike the first embodiment, the surface cleaning apparatus of the present embodiment is not provided with a dirt collection box, so that there is no need to wash the dirt collection box.

It should be noted that the mop of this embodiment can be a cleaning roller or a rotating disc mop.

Third embodiment of the present application:

although not shown in the drawings, in the washing step of the present embodiment, unlike the second embodiment, the cleaning roller is kept rotating at a high rotation speed, for example, at 400 revolutions per minute. Alternatively, the rotation is switched at high and low rotational speeds, for example, at 400 rpm and 200 rpm alternations.

Fourth embodiment of the present application:

although not shown in the drawings, unlike the foregoing embodiment, the self-cleaning method of the present embodiment further includes a judgment step before the cleaning step:

judging whether the surface cleaning device is in an upright state, if so, starting the cleaning step; if not, the self-cleaning is finished.

Specifically, the connecting position of the machine body and the cleaning head is provided with the trigger device, only when the machine body is in an upright state, the trigger device between the machine body and the cleaning head is triggered, at the moment, a user can open the surface cleaning device to start self-cleaning, otherwise, the user cannot start the surface cleaning device, so that the stability of the surface cleaning device placed on the cleaning assembly can be ensured, and the surface cleaning device is prevented from falling down due to vibration in the cleaning process.
