Description

Winding object cleaning method of cleaning system

Technical Field

The invention relates to the technical field of cleaning appliances, in particular to a method for cleaning windings of a cleaning system.

Background

The cleaning system is a household cleaning appliance which is commonly used in daily life for cleaning a surface to be cleaned. In addition to the advantages of simple operation and clean cleaning, cleaning systems generally have the advantage of rechargeable and automatic cleaning roller brushes. The actual use scene of the user usually has a filament winding, and the filament winding has the characteristics of light weight, thin weight, long length and toughness and is easy to wind and attach on the roller brush. The self-cleaning of the roller brush mainly depends on the rotation of the roller brush and the soaking and scouring of cleaning liquid to reduce the adhesion force of dirt on the roller brush, and then the dirt enters the dirt suction channel under the suction force generated by the dirt suction motor and the suction force so as to be finally collected in the sewage tank to finish the self-cleaning of the roller brush. The self-cleaning process can be completed without manual operation of a user, and time and labor are saved. However, if the filament windings are wound on the roller brush, the filament windings are repeatedly wound along with the rotation of the roller brush, so that the filament windings cannot fall off from the roller brush along with the rotation of the roller brush and the scouring soaking of the cleaning liquid, and the filament windings are wound on the roller brush more tightly along with the rotation of the roller brush, so that the brush hair of the roller brush is damaged, and the service life is prolonged. If the user does not manually clean the windings and directly enters the self-cleaning device, on one hand, the windings can be wound more tightly on the roller brush along with the rotation of the roller brush, so that the bristles are damaged, and the service life is prolonged. On the other hand, the winding object is tightly wound on the roller brush, so that part of other dirt on the roller brush is wrapped in the brush hair of the roller brush by the winding object, and the problem of unclean self-cleaning caused by the fact that the winding object cannot be cleaned in self-cleaning is solved.

At present, an auxiliary cleaning accessory is generally provided for a user in the prior art, when the roller brush is manually cleaned by the user through the auxiliary cleaning accessory after being wound by a winding object, the user is required to hold the roller brush by one hand in the manual cleaning process to fix the roller brush, and the winding object is taken down after being cut off by holding the auxiliary cleaning accessory, so that the winding object cleaning method increases the workload of the user, and is time-consuming and labor-consuming, thereby causing the problem of complaints of the user.

step S30: the roller brush rotates at a first rotational speed n1 in a first direction to cause the filiform windings to form clusters on both sides of the wiper strip, wherein n1 is 150rpm or less and 3000rpm or less.

Further, after the step S30, the method further includes:

step S331: the roller brush rotates towards a second direction by a second preset angle beta;

step S332: a cutting knife moves to cut the filiform winding;

step S333: the roller brush rotates towards a first direction;

further, the included angle between the scraping strip and the cutting knife is omega, and the second preset angle beta=omega±10°.

Further, the cleaning method of the cleaning machine further comprises the following steps:

and S40, rotating the roller brush, and starting the dirt sucking motor.

A surface cleaning system comprising a cleaning method of the cleaning machine of any one of claims 1-6, wherein the cutter blade is provided with serrated cutting teeth, serrated openings exist between adjacent cutting teeth on the same assembly, the cutter blade comprises a movable cutter assembly with serrated cutting teeth which moves along the axial direction of a roller brush, the roller brush comprises a brush roller and bristles covered on the surface of the brush roller, and the serrated openings of the movable cutter assembly are smaller than the diameter of the bristles of the roller brush.

Further, the cutting knife further comprises a static knife assembly with a serrated opening, the movable knife assembly is located above the static knife assembly and is in interference with the roller brush, and the interference between the movable knife assembly and the roller brush is smaller than that between the static knife assembly and the roller brush.

Further, the bristle height h1, the depth of the static knife component inserted into the roller brush bristle is L1, and L1 is more than or equal to 0.5mm and less than or equal to (h 1-1).

In summary, the method for cleaning the windings of the cleaning system at least includes the following steps: the cutter moves to cut the winding, the roller brush rotates by a first preset angle, the steps are circularly executed until the first stop condition is met, and at least one action of cutting the winding by the cutter moves is performed after the first stop condition is met. The circular cleaning step of the cutting knife to cut and the roller brush to rotate at a small angle, wherein the cutting knife moves to cut again, and the roller brush rotates at a fixed angle again, so that the slender windings wound on the roller brush rotate along with the angle of the roller brush and then cut and divide into small sections of filiform substances. Preferably, the filaments are made to have a length less than the circumference of the roller brush and are not able to continue to wrap around the roller brush and disengage from the roller brush. The winding on the roller brush can be cleaned without manual operation of a user.

And circularly executing the cleaning steps of cutting knife movement cutting and fixed angle rotation of the roller brush until a first stopping condition is met, wherein the first stopping condition can be the circulation execution times or the circulation execution time, so that the windings wound on the roller brush are cut into small sections with the number of not less than two sections, and cannot be wound on the roller brush along with the rotation of the roller brush. And after the first stopping condition is met, at least one cutting knife movement cutting action is performed to ensure that the winding material wound on the roller brush is cut into small sections. The winding cutting method comprises the steps of rotating a roller brush according to a preset angle in the winding cutting process, stopping rotating, cutting, rotating according to the preset angle again, and cutting again. The device has the advantages that the phenomenon that the roller brush does not rotate the cutting knife, and the cutting knife can only cut the winding which forms a ring shape into a linear winding at the same position of the winding even if the roller brush reciprocates is avoided, and the winding is not divided into a plurality of small sections. If the roll brush rotates again to collect the cut windings, the thread windings can be wound on the roll brush again along with the rotation of the roll brush, so that the previous cleaning step is ineffective. Therefore, when the winding is cleaned, the cutting knife moves to cut the winding which is towards the cutting knife when the winding is stopped, the roller brush rotates according to a preset angle after the cutting is completed, other positions of the winding of the roller brush face the cutting knife, and the cutting knife moves to cut the winding, so that the winding wound on the roller brush along the circumferential direction of the roller brush is cut into small sections.

Furthermore, the range of the first preset angle alpha is more than or equal to 10 degrees and less than 360 degrees, if alpha is too small, firstly the rotation of the roller brush to a fixed angle is difficult to control, the electric control design cost is increased due to high precision requirements, secondly the rotation angle is too small, the cutting needs to be circularly performed for a plurality of times to finish 360-degree cleaning of windings on the roller brush, the small-angle rotation cleaning time is long, and the waiting time of a user is prolonged. Thirdly, if alpha is too small, the cutting knife cuts the windings on the roller brush to form small sections with too small length, so that the small sections are not easy to collect along with the rotation of the roller brush, and the small filiform substances with lighter mass possibly fall to the ground or even fly in the air under the influence of air flow in the rotation process of the roller brush, so that secondary pollution is not easy to clean.

The cleaning machine 100 includes a roller brush that rotates to wipe a surface to be cleaned, which may be a single roller brush, a double roller brush, or a multiple roller brush. The roller brush includes a brush roller 62 and bristles 61 covered on the surface of the brush roller 62, the height of the bristles 61 is h1, and the diameter of individual bristles 61 is Φ1. In this embodiment, the roller brush is exemplified as a single roller. The cleaning machine 100 further includes a housing having a roller brush cavity for receiving the roller brush. The roller brush cavity can be semi-closed or open.

The cleaning machine 100 further comprises a liquid supply assembly, wherein the liquid supply assembly comprises a clean water tank 5 and a liquid conveying channel, and clean water, cleaning liquid or a mixture of the clean water tank 5 and the cleaning liquid or cleaning medium such as disinfectant can be contained in the clean water tank.

The cleaning machine 100 may further be provided with a liquid heating component for heating the cleaning medium in the clean water tank 5 or the cleaning medium flowing through the liquid conveying channel to achieve sterilization and disinfection of the surface to be cleaned in a hot water washing manner or to provide hot water for sterilization and disinfection of the roller brush in the process of self-cleaning of the roller brush, so as to ensure cleaning of the roller brush.

Further, the cleaning system further includes a cleaning tray 200, and the cleaning tray 200 is configured to house the cleaning machine 100. The cleaning tray 200 may also have charging contacts to interface with charging terminals on the body of the cleaning machine 100 to charge the cleaning machine 100. The cleaning tray 200 may further include a cleaning tank for accommodating the roller brush of the cleaning machine 100, and the roller brush may be accommodated for self-cleaning of the cleaning machine 100. In particular, the wall surface of the cleaning tray 200 is also provided with an air outlet facing the roller brush, and a fan and an air flow channel are arranged in the cleaning tray 200 to guide air flow generated by the fan to the air outlet and finally blow the air flow to the roller brush to dry the roller brush. A heating device is arranged in the airflow circulation air duct or the cleaning tank of the cleaning tray 200 to heat the air flowing through the airflow circulation air duct or to use the hot air to dry the roller brush or directly dry the roller brush to sterilize the roller brush to avoid bacteria,

Further, the cleaning system further comprises a cutter 1. The cutter 1 may be provided on the cleaning machine 100 or on the cleaning tray 200. The cutter blade 1 is fixedly or detachably mounted on the cleaning tray 200 or the cleaning machine 100. Preferably, the cutter 1 is fixedly or detachably mounted on the side wall of the cleaning tray 200, the cleaning bath, in a roll brush chamber of the cleaning machine 100, or on a roll brush.

The cutting blade 1 is at least arranged to be partially in interference with the roller brush when cutting the filiform wound.

Preferably, the cutter 1 is a guillotine with a blade. When the windings wound on the roller brush are cleaned, the guillotine moves along the width direction of the roller brush to the dirt sucking port direction to cut the windings.

Preferably, the cutting blade 1 is a cutting blade 1 with serrated cutting teeth. The cutter 1 comprises at least a movable blade assembly 11 which is reciprocatingly movable in the length direction of the roll brush, i.e. in the direction of the roll brush axis. There are saw tooth openings between adjacent cutting teeth on the moving blade assembly 11. The moving blade assembly 11 interferes with the roller brush and moves along the circumferential direction of the roller brush when removing the wound material wound around the roller brush, and the wound material is wound around the roller brush along the circumferential direction of the roller brush. When the movable cutter assembly 11 is inserted into the saw tooth opening between the adjacent cutting teeth of the movable cutter assembly 11 when the roller brush and the roller brush are in interference, the winding at the saw tooth opening hinders the movable cutter assembly 11 from moving when the movable cutter assembly 11 moves along the axial direction of the roller brush, and the winding contacts with the saw tooth-shaped cutting teeth along with the movement of the movable cutter assembly 11. The serrated cutting teeth have sharp edges and the moving blade assembly 11 contacts and severs the wound material during axial movement of the roll brush.

Preferably, the serrated opening L3 of the moving blade assembly 11 is smaller than the diameter phi of the individual bristles 61 of the roll brush. The moving blade assembly 11 is disposed in interference with the roller brush during the cutting of the winding. The serrated cutting teeth of the moving blade assembly 11 are thus inserted not only into the windings on the roller brush but also into the bristles 61 of the blade roller brush. One end of the brush hair 61 is coated on a brush roller 62 of the roller brush, and the other end is a free end which can swing freely. The interference arrangement of the movable cutter assembly 11 with the roller brush means that the movable cutter assembly 11 is inserted from the free ends of the bristles 61 toward the fixed ends of the bristles 61 coated on the brush roller 62. During the process of the serrated cutting knife 1 moving along the axial direction of the roller brush, the brush hair 61 meets the cutting knife 1, and the cutting knife 1 can be prevented from cutting by the free end swinging. However, if the bristles 61 are caught in the saw tooth openings between the adjacent cutting teeth of the movable cutter assembly 11, the free ends of the bristles 61 meeting the cutting teeth at one end in the saw tooth openings can only swing along with the movement of the cutting knife 1 in the direction of the movement of the cutting knife 1, and meet the cutting teeth at the other end in the swinging process and finally are cut by the cutting teeth. So that the brush bristles 61 of the roller brush become short and short, affecting the cleaning effect of the cleaning machine 100, resulting in the roller brush being scrapped in advance. The serrated opening of the moving blade assembly 11 is thus made smaller than the diameter of the individual bristles 61 of the roll brush, and the bristles 61 of the roll brush cannot be caught in the serrated opening between adjacent cutting teeth. The cutter 1 does not damage the bristles 61 during the cutting of the windings by moving in the direction of the axis of the roll brush.

Preferably, the cutting knife 1 further comprises a static knife assembly 12, wherein the static knife assembly 12 is in interference arrangement with the roller brush when removing the winding matters, and is used for fixing the winding matters on the roller brush so that the movable knife assembly 11 can better cut the winding matters. When the moving blade assembly 11 moves to cut the windings on the roller brush, the windings may be loosely wound on the roller brush and can move together with the moving blade assembly 11 so that the moving blade assembly 11 cannot cut the windings. Therefore, the interference arrangement of the static knife assembly 12 and the roller brush is static in the process of cutting the winding, so that the winding is fixed on the roller brush under the action of the static knife assembly 12, and the winding is not easy to move along with the movable knife assembly 11 to avoid cutting. When the movable blade assembly 11 moves to the winding position, the static blade assembly 12 presses the winding material which cannot move randomly on the roller brush, and the movable blade assembly 11 cuts off.

Preferably, the stationary blade assembly 12 may be a guillotine or serrated cutting blade 1 with serrated openings. The interference between the movable blade assembly 11 and the roller brush is smaller than the interference between the static blade assembly 12 and the roller brush when cutting the windings. On the one hand, the winding is fixed by the static knife assembly 12, and the force exerted on the winding by the static knife assembly 12 is larger than the thrust to the winding when the moving knife assembly 11 moves, so that the winding cannot move along the axial direction of the roller brush along with the movement of the moving knife assembly 11, and the cutting effect is better.

Preferably, the static blade assembly 12 is disposed in interference with the bristles 61 at least during cleaning of the windings, the static blade assembly 12 being inserted into the bristles 61 to a depth L1. Preferably, the optimal dimension of L1 is 0.5 mm.ltoreq.L1.ltoreq.h1-1 mm, specifically, the depth of insertion of the static blade assembly 12 into the bristles 61 during cleaning of the windings is 0.5mm or more so that the static blade assembly 12 applies sufficient force to the bristles 61 and their windings to prevent the windings from moving during cutting, affecting the cutting effect. On the other hand, the depth of the static cutter assembly 12 into which the bristles 61 are inserted is equal to or less than 1mm less than the length of the bristles 61, i.e., a gap of at least 1mm exists between the static cutter assembly 12 and the root of the bristles 61 when the static cutter assembly 12 is inserted into the bristles 61. The excessive depth of the static cutter assembly 12 inserted into the brush hair 61 is avoided to influence the adhesion firmness between the brush hair 61 and the brush roller 62, so that the brush hair 61 is prevented from falling off. On the other hand, the static blade assembly 12 is inserted too deeply into the brush bristles 61, so that the gap between the brush bristles 61 and the brush bristles 61 is easily enlarged after long-term insertion, and the roller brush is damaged to affect the cleaning effect, so that the roller brush is scrapped in advance.

Preferably, the stationary blade assembly 12 is a serrated cutting blade 1 with serrated openings. The saw tooth opening L3 of the movable blade assembly 11 is smaller than or equal to the saw tooth opening L2 of the static blade assembly 12. The diameter of the single winding of the filiform winding is far smaller than that of the single bristle 61, the smaller the saw tooth opening of the movable cutter assembly 11 is, the winding wound on the roller brush can be split into different parts by utilizing the saw teeth and the saw tooth opening to be respectively positioned in the different saw tooth openings, and the fewer the winding accommodated in the single saw tooth opening is, the winding is more easily cut off. The saw tooth opening of the cutter 1 should be as small as possible while being smaller than the diameter of the individual bristles 61 and larger than the diameter of the individual windings.

Preferably, the movable blade assembly 11 is located above the stationary blade assembly 12, and may also be located below the stationary blade assembly 12. In this embodiment, the movable blade assembly 11 is located above the stationary blade assembly 12, and the distance between the stationary blade assembly 12 and the movable blade assembly 11 is L4. Further, L4 is more than or equal to 0.2mm and less than phi 1/2, namely, the distance between the end face of the cutting edge of the static cutter assembly 12 and the end face of the cutting edge of the movable cutter assembly 11 is more than or equal to 0.2mm. Certain gaps are reserved between the static knife assembly 12 and the movable knife assembly 11, so that on one hand, the static knife assembly 12 is prevented from being contacted with the movable knife assembly 11, the static knife assembly 12 and the movable knife assembly 11 are rubbed with each other, friction force prevents the static knife assembly 12 from moving to cut the winding, and the winding removal effect and efficiency are affected. The distance between the end surface of the cutting edge of the static cutter assembly 12 and the end surface of the cutting edge of the movable cutter assembly 11 is less than half of the diameter of the bristles 61 of the single roller brush, so that the bristles 61 are prevented from being cut by the movable cutter assembly 11.

Preferably, the saw tooth openings of the movable cutter assembly 11 are staggered with the saw tooth openings of the static cutter assembly 12, so that the bristles 61 are prevented from being wound into the saw tooth openings, and seven windings are better.

The present embodiment describes a method of cleaning a winding on an automatic cleaning roller brush by taking a cleaning system with a cleaning tray 200 and a cutter 1 on the cleaning tray 200 as an example.

Further, the winding cleaning method comprises the following steps:

step S10, the cutting knife 1 moves to cut the winding;

step S20: the roller brush rotates by a first preset angle alpha;

and executing the step S10 and the step S20 circularly until the first stopping condition is met, and executing the step S10 at least once again after the first stopping condition is met.

After the cleaning machine 100 completes one cleaning operation, the user places it on the cleaning tray 200 for self-cleaning. The liquid supply assembly supplies liquid to wet the roller brush or the surface to be cleaned in the process of cleaning the surface to be cleaned, and the roller brush rotates to clean the surface to be cleaned. Because of the existence of the filiform winding on the surface to be cleaned, at least one end of the filiform winding is contacted with the roller brush and winds the roller brush along the circumferential direction of the roller brush along with the rotation of the roller brush during the process of wiping the surface to be cleaned by the roller brush. The windings wound on the roller brush during cleaning are difficult to remove. After the user completes the cleaning operation, the roller brush still has the windings wound thereon. Therefore, after the user places the cleaner 100 on the cleaning tray 200, the above-described entanglement cleaning step is performed to clean the entanglement of the roller brush before the self-cleaning starts.

Preferably, the cutter 1 on the cleaning tray 200 may be located in the cleaning bath of the cleaning tray 200 or may be located on the sidewall of the cleaning tray 200. In this embodiment, the dicing blade 1 is located on the side wall of the cleaning tray 200.

Preferably, the cutter 1 may be provided as the cutter 1 fixed to the cleaning tray 200, or may be provided as a retractable cutter 1. The retractable cutter 1 moves towards the direction of the roller brush when cutting the winding material and cuts the winding material by interference with the roller brush, and the retractable cutter 1 is retracted to a storage position before the roller brush rotates or after the winding material cleaning step is finished after the cutting operation is finished, so that the cutter 1 interfering with the roller brush is prevented from obstructing the roller brush to rotate or damaging the brush hair 61.

The cleaning machine 100 is placed on the cleaning tray 200, and the retractable cutter 1 is extended to the direction of the roller brush to be in interference with the roller brush according to the instruction of a user or automatically. Or the cutting knife 1 is positioned on the cleaning tray 200 and is not telescopic, and the position relation of interference between the cutting knife 1 and the roller brush can be met after the cleaning machine 100 is placed on the cleaning tray 200. Step S10 is performed: the cutter 1 moves to cut the winding. The cutter 1 cuts the winding that is now directed towards the cutter 1. The cutting knife 1 may be moved to cut the winding, or may be cut only once, or may stop moving after the cutting knife 1 moves for a preset time, or may determine the movement stop time of the cutting knife 1 according to whether the winding facing the cutting knife 1 is cut.

After the execution of step S10 is completed, the movement of the cutter 1 is stopped, and step S20 is executed: the roller brush is stopped after rotating by a first preset angle alpha. Preferably, the first preset angle alpha is in the range of 10 degrees less than or equal to alpha less than 360 degrees. The roll brush which completes one cut is cut, but the roll brush which is wound in the circumferential direction can be cut only by cutting on the plane of the same horizontal line, and small sections are not formed. If the roll brush is again rotated for a long time the wrap will be rewound around the roll brush. Thus, the roller brush is controlled to rotate by the first preset angle alpha after the cutting knife 1 stops cutting. In particular, the first preset angle α is greater than or equal to 10 ° so that the winding that faces the cutter 1 after rotating is located at a certain distance from the winding position cut by the cutter 1 last time, so that the winding is prevented from being separated into a small broken length and a long large length by too short cutting positions twice, and the length of the remaining large length winding is still greater than the circumferential circumference of the roller brush, and can be wound on the roller brush again. On the other hand, if the rotation angle of the roller brush is too small, the position of the windings facing the cutter knife 1 after rotation is too close to the position of the windings cut by the cutter knife 1 last time, the cutter knife 1 is cut into too small fragments, the surrounding air flow is fluctuated along with the secondary rotation of the roller brush, and the filiform windings of the small fragments possibly fly away from the air of the cutter knife along with the air flow to cause secondary pollution. Or the small fragments fall to the cleaning dead angle of the cleaning tray 200 and are not easy to be stored and cleaned. The first preset angle α cannot be too small, and is preferably 10 ° or more. On the other hand, the first preset angle α is smaller than 360 °, i.e. the roll brush cannot rotate more than one revolution. Otherwise, the winding which is not cut into small sections may be wound on the roller brush again along with the rotation of the roller brush, so that the cutting action of the cutter 1 is invalid in the last time, and the winding cannot be cleaned.

Preferably, steps S10 and S20 are cyclically performed until the first stop condition is satisfied. That is, the rotation is performed to cut the wound material, the roller brush rotates so that the portion of the wound material which is not cut is directed to the cutter blade 1, the cutter blade 1 cuts the wound material, and the roller brush rotates … … again.

Preferably, the first stop condition may be a number of cycles N, where N is an integer, N.gtoreq.360 DEG/alpha. Even if the roller brush is rotated at least cumulatively not less than 360 ° in the course of performing steps S10 and S20 in a cycle, the cutter 1 cuts the winding into a plurality of segments in the circumferential direction of the roller brush, so that the cut winding cannot be continuously wound on the roller brush.

Preferably, the first stop condition may also be a cycle time T,1 s.ltoreq.T.ltoreq.30s, such that step S10 and step S20 cycle long enough for the cutter 1 to cut the winding into sections.

Preferably, the angle of each rotation of the roller brush may be the same or different within the range defined by the first preset angle α during the cyclic execution of step S10 and step S20. For example, steps S10 and S20 are cyclically performed, the cutter cuts the winding, the roller brush rotates by 30 °, the cutter cuts the winding again, and the roller brush rotates by 30 ° again until the first stop condition is satisfied.

The steps S10 and S20 may be cyclically performed, the cutter cuts the winding again by 30 ° and the roller brush rotates by 45 ° … …, each time the rotation angle of the roller brush is different, until the first stop condition is satisfied.

Preferably, steps S10 and S20 are performed in a loop until step S10 is performed at least once more after the first stop condition is satisfied. In the above-mentioned circulation step, the movement of the cutter 1 is always performed in a circulation manner to cut the winding on the horizontal surface corresponding to the cutter 1 on the roller brush, the roller brush rotates to make the other positions of the winding which is not cut face the cutter 1, and the cutter 1 cuts the winding corresponding to the cutting. When the first stopping condition is met, the roller brush just completes executing the step S20, namely, the roller brush rotates by the first preset angle α, so that a certain part of the winding which is not cut faces the cutter 1, in order to cut the winding into small sections as small as possible or cut the winding into small sections by the cutter 1 after rotating by each small angle in the process of 360 degrees, the roller brush can not continue winding the roller brush along the circumferential direction along with the rotation of the roller brush after executing the step S10 and the step S20 at least once after executing the step S10 for stopping the cycle of the first stopping condition, namely, executing the step of cutting the winding by moving the cutter 1 at least once again, so that the winding corresponding position of the winding facing the cutter 1 is cut by the cutter 1 after stopping the rotation of the roller brush each time, and the winding is ensured to be divided into small sections.

Further, the method for cleaning the winding comprises the following steps:

and (3) circularly executing the step S10 and the step S20 until the first stop condition is met, and executing the step S20 at least once again after the first stop condition is met, wherein the winding material cleaning method at least further comprises the following steps:

step S30: the roller brush rotates at a first rotational speed n1 in a first direction to cause the filiform wound to agglomerate. Preferably, 150 rpm.ltoreq.n1.ltoreq.3000 rpm.

Further, the roller brush rotates in a first direction, which may be the same as or opposite to the direction of rotation of the cleaning machine 100 when the cleaning machine 100 cleans the surface to be cleaned.

Further, the cleaning machine 100 also includes a wiper strip in interference fit with the roller brush, the wiper strip being located within the roller brush cavity. In step S30, the roller brush rotates, so that the cut windings attached to the surface of the roller brush rotate along with the roller brush, and are blocked by the scraping strip from being separated from the roller brush when encountering the scraping strip which is in interference arrangement with the roller brush, so that the windings are agglomerated.

Preferably, the thread-like windings are agglomerated on one side of the scraper bar. In particular, the thread-like windings may be agglomerated on the upper side of the wiper strip or on the lower side of the wiper strip. The position of the wire-like winding relative to the wiper strip is dependent on the first direction of rotation of the roller brush. If the roller brush rotates in the same direction as the rotating direction when cleaning the surface to be cleaned in step S30, the filiform entanglement is agglomerated on the lower side of the wiper strip, and if the roller brush rotates in the opposite direction to the rotating direction when cleaning the surface to be cleaned, the filiform entanglement is agglomerated on the upper side of the wiper strip.

Preferably, the execution of step S30 is stopped after the preset time t1 is satisfied. In particular, t1 is not less than 1s, so that all the windings which are attached to the roller brush and cut into small sections are gathered at the scraping strip to form a group, and are separated from the roller brush.

After the step S30 is completed, the user may manually remove the wound material that has been agglomerated at the wiper strip.

Further, the cleaning machine 100 also includes a soil pick-up assembly. The soil pick-up assembly includes a soil pick-up channel 4 communicating with the roller brush to pick up soil, a soil tank 3 communicating with the soil pick-up channel 4 to recover the soil, and a soil pick-up motor 2 communicating with the soil pick-up channel 4 and the soil tank 3 to provide suction thereto. The dirt suction channel 4 comprises a dirt inlet and a dirt suction port, the dirt suction port is positioned in a roller brush cavity and communicated with the roller brush, and a roller brush cavity wall which is inclined from two sides of the roller brush to the direction of the dirt suction port is also arranged in the roller brush cavity so as to guide dirt to enter the dirt suction port. The sewage inlet is positioned in the sewage tank 3 or on the wall surface of the sewage tank 3 so that the sewage suction channel 4 is communicated with the sewage tank 3. The sewage inlet can face the direction of the sewage suction motor 2, can face away from the direction of the sewage suction motor 2, and can face the wall surface of the sewage tank 3.

Preferably, the dirt inlet faces the direction of the dirt sucking motor 2, and the dirt sucking motor 2 has smaller loss, so that the air flow in the dirt sucking channel 4 flows towards the direction of the dirt sucking motor 2 under the action of the suction force of the dirt sucking motor 2.

Preferably, the sewage inlet is opposite to the sewage suction motor 2 or faces the wall surface of the sewage tank 3. Dirt is carried over by the air current and is separated from the dirt inlet through the dirt absorbing channel 4, the dirt has higher movement speed when being separated, in order to avoid dirt or water vapor from entering the dirt absorbing motor 2 to cause damage to the dirt absorbing motor 2 because the dirt is carried over by the air current and continues to move towards the dirt absorbing motor 2, the dirt absorbing port is arranged on the wall surface facing away from the dirt absorbing motor 2 or towards the sewage tank 3 to avoid damage to the motor because the dirt is separated from the dirt absorbing motor 2 and moves towards the dirt absorbing motor 2 without blocking.

Further, the method for cleaning the winding comprises the following steps:

step S40, the roller brush rotates, and the sewage suction motor 2 is started.

Preferably, step S40 follows step S30. After the windings cut into small sections are clustered on one side of the scraping strip, the dirt sucking motor 2 starts the roller brush to rotate. Preferably, the scraping strip is positioned on the upper side of the dirt sucking port in the roller brush cavity. Agglomerated hair enters the sewage suction channel 4 from the sewage suction port with the aid of the suction force of the sewage suction motor 2 and the rotary roller brush, and finally is collected in the sewage tank 3. The thread-like winding material wound on the roller brush is automatically cleaned. The winding can be cut, clustered and collected without manual operation of a user, so that time and labor are saved.

Example two

As shown in fig. 1 to 4 and fig. 6, the present embodiment is different from the other embodiments in that the winding material cleaning method includes the steps of:

step S10: the cutting knife moves to cut the winding;

step S20: the roller brush rotates by a first preset angle alpha;

step S10 and step S20 are circularly executed until the first stopping condition is met, and the step S10 is executed at least once after the first stopping condition is met;

step S30: the roller brush rotates at a first rotation speed n1 towards a first direction;

step S331: the roller brush rotates towards a second direction by a second preset beta;

step S332: a cutting knife moves to cut the filiform winding;

step S333: the roller brush rotates towards a first direction;

step S40: the roller brush rotates, and the sewage suction motor 2 is started.

After the cleaning machine 100 completes one cleaning operation, the filament windings on the surface to be cleaned are wound around the roller brush along the circumferential direction of the roller brush as the roller brush rotates, and cannot be removed. Thus, after the cleaning operation is completed, the cleaning machine 100 automatically cleans the windings in the above-described steps. The cutter 1 may be provided in a roll brush chamber of the cleaner 100 and may also be provided on the cleaning tray 200. The cutting knife 1 can stretch out when the winding is cut by telescopic movement, and can retract after cutting, or can be fixed and always arranged with the roller brush in an interference way, and the interference between the cutting knife 1 and the roller brush is relatively small, so that the roller brush is not greatly blocked from rotating. Preferably, the cleaning machine 100 is placed on the cleaning tray 200, and the retractable cutter 1 is extended to the direction of the roller brush to interfere with the roller brush according to the user's instruction or automatically. Or the cutting knife 1 is positioned on the cleaning tray 200 and is not telescopic, and the position relation of interference between the cutting knife 1 and the roller brush can be met after the cleaning machine 100 is placed on the cleaning tray 200.

Step S10 is performed: the cutter 1 moves to cut the winding. The cutter 1 cuts the winding that is now directed towards the cutter 1. The cutting knife 1 may be moved to cut the winding, or may be cut only once, or may stop moving after the cutting knife 1 moves for a preset time, or may determine the movement stop time of the cutting knife 1 according to whether the winding facing the cutting knife 1 is cut.

After the execution of step S10 is completed, the movement of the cutter 1 is stopped, and step S20 is executed: the roller brush is stopped after rotating by a first preset angle alpha. Preferably, the first preset angle alpha is in the range of 10 degrees less than or equal to alpha less than 360 degrees. Further, steps S10 and S20 are cyclically performed until the first stop condition is satisfied. That is, the rotation is performed to cut the wound material, the roller brush rotates so that the portion of the wound material which is not cut is directed to the cutter blade 1, the cutter blade 1 cuts the wound material, and the roller brush rotates … … again.

After the cutting of the cutter 1 is completed, the roller brush rotates at a small angle, … … is cut again by the cutter 1, the roller brush rotates at least in an accumulated way not less than 360 degrees, the winding which is abutted against the cutter 1 after the roller brush stops rotating each time is cut at least once, the circulation is stopped, and the winding is cut into a plurality of small sections which are attached to the surface of the roller brush and do not wind the roller brush. Step S30 is performed at this time: the roller brush rotates at a first rotation speed n1 towards a first direction, so that windings attached to the roller brush rotate along with the roller brush, and are blocked by scraping strips which are arranged in an interference manner with the roller brush to form clusters near the scraping strips in the moving process.

The lumpy entanglement is accumulated near the wiper strip, and may not smoothly enter the dirt suction port or smoothly flow in the dirt suction passage 4 when the entanglement volume is excessively large. It is therefore necessary to further crush it to make it easier to collect. After the step S30 is performed, a step S331 of rotating the roller brush in the second direction by a second preset angle β is performed. Preferably, the second direction is opposite to the first direction. The agglomerated windings are blocked by the scraping strip from agglomerating at the scraping strip attachment after the step S30 is completed. The roller brush rotates reversely along a second direction opposite to the first direction, and the mass wound accumulated on the scraping strip accessory moves to the vicinity of the cutting knife 1 under the drive of the rotating roller brush.

Preferably, the included angle between the scraping strip and the cutting blade 1 is Ω, and the second preset angle β=Ω±10°. So that the wound material agglomerated around the scraping strip is moved again to the cutter 1 along with the rotation of the roller brush, and is crushed and cut again.

After step S331 is performed, step S332 is performed: the cutter 1 moves to cut the filiform wound. The cutting knife 1 moves to cut the coil and shear the coil.

Preferably, the time for which the cutter 1 moves to cut the bolus winding in step S331 is at least longer than the accumulated execution time of step S10. The agglomerated windings have a compact internal structure and the multiple windings are intertwined together to form an integral body that is less prone to being cut as compared to windings wound on a roller brush. Therefore, a longer cutting time is required for thoroughly cutting the agglomerated windings than when cutting the windings wound on the roller brush to secure the cutting effect.

Further, after the execution of step S332, step S333 is executed: the roller brush rotates in a first direction. The wound cut near the cutter 1 is gathered again near the wiper strip. Preferably, the angle of rotation of the roller brush in step S333 is greater than β+10°, so that the windings are again gathered near the wiper strip.

After the windings are gathered again near the scraping strip, step S40 is performed: the roller brush rotates, and the sewage suction motor 2 is started. The cut windings are finally collected into the sewage tank 3 through the sewage suction channel 4 through the sewage suction port with the aid of the suction force of the sewage suction motor 2 and the rotation of the roller brush. The automatic collection of the windings is realized, manual operation of a user is not needed, time and labor are saved, and hands are not dirty.

Example III

As shown in fig. 1 to 4 and fig. 7, this embodiment is different from the other embodiments in that the winding material cleaning method includes the steps of:

step S10: the cutting knife moves to cut the winding;

step S20: the roller brush rotates by a first preset angle alpha;

step S332: a cutting knife moves to cut the filiform winding;

step S333: the roller brush rotates towards a first direction;

further, after the step S333 is performed, the cut windings are moved to the vicinity of the scraping bar again along with the rotation of the roller brush. However, in step S30, the wound material crushed into small pieces by the cutter 1 forms a lump around the scraping bar again along with the roller brush, and after the lump-shaped wound material is moved around the cutter 1 in step S331, the lump-shaped wound material is a lump-shaped material having a large diameter and not easily separated and formed by crisscross multi-section wire-shaped wound materials, so that the lump-shaped wound material is difficult to be thoroughly crushed by the cutter 1. Thus, after the step S30 is completed, a coil-like winding is formed around the wiper strip. The steps S331, S332, and S333 are circularly executed not less than three times. The winding materials which are clustered near the scraping strips are conveyed to the position near the cutting knife 1 along with the rotation of the roller brush, the cutting knife 1 cuts and pulverizes the clustered winding materials, after the winding materials are cut for a period of time, the cutting knife 1 stops moving, the roller brush rotates along the first direction to cluster the cut winding materials again near the scraping strips, and the roller brush rotates along the second direction to convey the winding materials to the cutting knife 1 again for cutting … … for at least three times after the clustering, so that the winding materials are cut into thin and short broken shapes.

Further, after thoroughly cutting up the windings, the dirt sucking motor 2 is started, the roller brush rotates at the same time, the windings are finally collected into the sewage tank 3 through the dirt sucking port and the dirt sucking channel 4, and the windings wound on the roller brush can be cleaned without manual cleaning by a user.

Thus far, the technical solution of the present application has been described in connection with the foregoing embodiments, but it is easily understood by those skilled in the art that the protective scope of the present application is not limited to only these specific embodiments. The technical solutions in the above embodiments may be split and combined by those skilled in the art without departing from the technical principles of the present application, and equivalent changes or substitutions may be made to related technical features, so any changes, equivalent substitutions, improvements, etc. made within the technical concepts and/or technical principles of the present application will fall within the protection scope of the present application.
