Description

TECHNICAL FIELD

[0001] The present application relates to the field of cleaning technology, and in particular, to a control method for a cleaning device.BACKGROUND

[0002] The cleaning device can clean the floor, and a cleaning task thereof can include performing wet cleaning to the floor. For example, a floor scrubber includes a liquid sprayer and a rolling brush, where the floor is wetted by the liquid sprayer, and then wetted stains on the floor is cleaned by the rolling brush, thereby realizing the wet cleaning function for the floor.

[0003] In order to reduce stains, existing floor scrubbers are equipped with a squeegee at a front end of the rolling brush, so that during a backward pulling process, the floor scrubber can use the squeegee to clean up the residual stains and impurities on the floor.

[0004] However, while adding the squeegee at the front end, it also brings a risk of increased stain pollution. For example, after the squeegee at the front end scrapes the stains, it will also carry a certain amount of stains, which also easily increase the risk of pollution.SUMMARY

[0005] The present application provides a control method for a cleaning device, which is used to address the problem that there are inadequacies of cleaning methods for residual stains in the existing floor scrubber.

[0006] In a first aspect, the present application provides a control method for a cleaning device, and the cleaning device includes a machine body and a handle connected to a rear side of the machine body, where the handle is configured to be gripped in hand by a user, a floor brush is connected to a lower end of the machine body, the floor brush is provided with a movable first squeegee and a rolling brush, and the first squeegee is provided at a front side of the rolling brush; where the method includes: receiving a stop instruction triggered by the user; if the first squeegee is located at a first position which is in contact with a to-be-cleaned surface, controlling the first squeegee to be lifted up to a second position, so that the first squeegee is not in contact with the to-be-cleaned surface; controlling the cleaning device to move in a direction away from the user, and stop moving when a moving distance reaches at least a first distance.

[0007] In the prior art, the cleaning device often has a problem of residual stains. For example, the floor scrubber, due to the high liquid content of the rolling brush itself, which will leave more stains on the cleaning surface after cleaning. A method for solving the residual stains has emerged in the current existing technology.

[0008] A front end of the floor brush is provided with a movable squeegee, which can be controlled to be in contact with or separated from the to-be-cleaned surface. When being pushed forwards, the front squeegee is lifted up, and when being pulled backwards, the front squeegee descends and is in contact with the to-be-cleaned surface so as to scrape and clean the to-be-cleaned surface, thereby significantly improving the problem of the residual stains on the cleaning surface. However, although the problem of the residual stains on the cleaning surface is improved, due to the fact that the front squeegee itself can be contaminated with some liquid or dirt and there is a certain distance between the front squeegee and the rolling brush cleaning area, so that a cleaning dead zone is easily formed in a distance between the front squeegee and the rolling brush cleaning area after the floor brush stops moving, so that a section of stain or dirt area will be formed on the cleaning surface. Besides, for example, the front squeegee will drip liquid towards the to-be-cleaned surface after the cleaning is completed and meanwhile there is a certain gap between the front squeegee and the rolling brush, so that the above gap belongs to a dead zone where the front squeegee cannot clean at the moment before stopping.

[0009] At the same time, it can be conceived that the users usually pull the floor scrubber close to themselves after pressing the stop button, so as to retract the floor scrubber. However, the front squeegee is provided at the front side of the floor brush, so that after the front squeegee drips the stains, or after the stains remain in the area between the front squeegee and the rolling brush, firstly, it is difficult for the users to observe them during shutdown. At the same time, according to behavioral habits, the users will only find the residue when they pull the floor scrubber towards themselves. Secondly, when the users want to clean again, they can only push the floor scrubber forward again or turn on the floor scrubber again for targeted cleaning the stains, so that the experience and visual perception are very poor.

[0010] In the present solution, by obtaining the stop instruction, the cleaning device is controlled to move, so as to clean up the residual stains at the above-mentioned position.

[0011] When the user presses the stop button, the cleaning device acquires the stop instruction, and at this moment, if the squeegee provided on the front side is in a position which is in contact with the to-be-cleaned surface, then the squeegee is controlled to be lifted up and detach from the to-be-cleaned surface and the cleaning device is controlled to move away from the user, so as to use the rolling brush to clean the residual stains at the above-mentioned position, so that the residual stains in the dead zone at the front side can be eliminated. Meanwhile, by lifting the squeegee provided on the front side, the stains on the first squeegee can be further dropped, and the residual liquid thereon can be thrown off by the lifting action, thereby preventing further residual stains from being generated after the residual stains are completely cleaned.

[0012] In the above-mentioned solution, by controlling the cleaning device to move forward after obtaining the stop instruction, the fixed thinking of the user can be broken, so that cleaning dead zone that are inevitable but hardly conceivable at all can be cleaned, thereby further enhancing the experience.

[0013] In an embodiment of the present application, the machine body is further provided with a second squeegee, which is provided at a rear side of the rolling brush; and after controlling the cleaning device to move in the direction away from the user, the method further includes: when the moving distance reaches the first distance, controlling the cleaning device to move in a direction close to the user; and during a process of the cleaning device moving in the direction away from the user, the second squeegee is in contact with the to-be-cleaned surface, and stops moving when the moving distance reaches at least a third distance.

[0014] If the cleaning device is provided with the second squeegee which cannot move, in order to achieve a collection function of the second squeegee, the second squeegee needs to be grounded, and a dead zone gap is also formed between the second squeegee and the rolling brush. During an actual cleaning process, the dead zone between the second squeegee and the rolling brush is completely hidden under the floor brush, so that the residual stains are even more unpredictable by the user. Therefore, a backward movement operation moving in a direction close to the user is added after shutdown, so as to clear the dead zone gap between the second squeegee and the rolling brush, thereby improving the stains cleaning effect.

[0015] To this end, on the basis of the first squeegee and in cooperation with the second squeegee, the residual stains caused by pushing forward and pulling backward can be respectively solved. After the cleaning device acquires the stop instruction, the cleaning device is respectively controlled to move in the direction away from the user and in the direction close to the user, which can also solve the problem of the residual stains brought by different squeegees themselves simultaneously.

[0016] Based on this, by means of the mutual combination of the above-mentioned solutions, the current floor scrubber can produce almost zero stains, and the cleaning effect and user experience are much superior to those of the floor scrubber in the prior art.

[0017] Optionally, a liquid separator and a wiper strip are provided inside the floor brush, where the liquid separator is configured to supply liquid to the rolling brush so as to keep the rolling brush in a wet state, the wiper strip is configured to squeeze liquid from the rolling brush, and a suction device is further provided inside the machine body, and when the cleaning device moves in the direction away from the user, the liquid separator is controlled to stop supplying liquid and the suction device is kept in a suction state, so that the rolling brush can absorb stains on the to-be-cleaned surface during a movement process of the cleaning device.

[0018] After receiving the stop instruction, the liquid separator is controlled to no longer provide liquid, and at the same time, the liquid-squeezing ability of the wiper strip is utilized, and the suction device is controlled to suck, so that the liquid content of the rolling brush can be prevented from being in a saturated state, and thus the stains on the to-be-cleaned surface can be further absorbed by controlling the rolling brush to move in the direction away from the user.

[0019] Optionally, when the cleaning device moves in the direction away from the user, a suction force of the suction device is controlled to be greater than or equal to 10000 Pa.

[0020] The suction device here can be a suction motor. As mentioned above, during the movement process of the cleaning device, the suction force of the suction device is kept greater than or equal to 10000 Pa, so that the liquid content of the rolling brush can be further ensured to be within a reasonable range, thereby enhancing the ability to clean residual stains.

[0021] Optionally, the wiper strip is configured to be movable relative to the rolling brush, and when the cleaning device moves in the direction away from the user, the wiper strip is controlled to move away from the rolling brush, and a suction force of the suction device is controlled to be greater than or equal to 10000 Pa.

[0022] In an embodiment, the above-mentioned wiper strip is provided to be movable. Specifically, a fixed side of the wiper strip is provided with a driving device, for example, a cam structure, a connecting rod structure, a linear motor, etc. By means of the above-mentioned driving device, the wiper strip can be controlled to be away from or close to the rolling brush, thus achieving control of the liquid content of the rolling brush.

[0023] When the cleaning device move in the direction away from the user, the wiper strip is controlled to move away from the rolling brush, that is, the rolling brush is no longer squeezed by the wiper strip, that is, ensuring that the rolling brush has a certain liquid content, so that not only the stains in the dead zone can be absorbed, but also the residual dirt can be cleaned.

[0024] At the same time, by controlling the suction force of the suction device to be greater than 10,000 Pa, the suction effect after stopping can also be ensured. That is to say, the implementation of this solution can not only solve the problem of residual stains and dirt, but also ensure that the rolling brush itself no longer has any residue.

[0025] Optionally, after controlling the cleaning device to move in the direction away from the user, the method further includes: when the moving distance reaches the first distance, controlling the cleaning device to move in the direction close to the user, and stop moving when the moving distance reaches at least a second distance, so that debris formed in the dead zone gap between the second squeegee and the rolling brush is also cleaned, and a task of cleaning residual stains is completed with a minimum driving control distance.

[0026] In an embodiment of the present application, the first distance is configured to be a minimum distance from a contact point of the rolling brush with the to-be-cleaned surface to a contact point of the first squeegee with the to-be-cleaned surface.

[0027] In the present embodiment, the moving distance of the floor brush is defined to be associated with a distance between the rolling brush and the first squeegee, so as to more precisely complete the cleaning task of the impurities in the dead zone, thereby ensuring that there will be no missed cleaning phenomenon.

[0028] In an embodiment of the present application, the first distance is configured to be 1 / 4-3 / 4 of circumference of the rolling brush.

[0029] In the present embodiment, the moving distance of the floor brush is defined to be associated with the circumference of the rolling brush, so that the moving distance can be indirectly controlled by simply controlling a rotation angle of the rolling brush. The control method is simpler and is applicable to cleaning devices in different models and rolling brushes in different sizes, thereby ensuring that the cleaning moving distance satisfies the length of the dead zone and improving the cleaning effect of the cleaning device.

[0030] In an embodiment of the present application, the third distance is configured to be a sum of the first distance and a second distance, and the second distance is configured to be a minimum distance from a contact point of the rolling brush with the to-be-cleaned surface to a contact point of the second squeegee with the to-be-cleaned surface.

[0031] A gap distance formed between the first squeegee at the front side of the rolling brush and the rolling brush is defined as the first distance, and a gap distance formed between the second squeegee at the rear side of the rolling brush and the rolling brush is defined as the second distance. After shutdown, since the gap distances between the two squeegees are cleaning dead zones, so that it can be ensured that the dead zone gap on the front side of the rolling brush is cleaned by moving forward for the first distance, and it can be ensured that the dead zone gap of the second distance on the rear side of the rolling brush is cleaned while extending a backward moving distance by moving backward for the sum of the first distance and second distance, thereby further improving the cleaning effect on the rear side of the rolling brush, and also restoring the first distance away from the user.

[0032] In an embodiment of the present application, when the cleaning device moves in the direction close to the user by at least the third distance, an angle between a side of the machine body facing towards the user and the to-be-cleaned surface is between 70 degrees and 100 degrees.

[0033] Since the cleaning device needs to be stored upright after stopping cleaning, that is, the angle between the machine body and the to-be-cleaned surface is between 70 degrees and 100 degrees, therefore, the storage operation of the cleaning device can be achieved while using active cleaning of the residual stains.

[0034] In an embodiment of the present application, the second squeegee is a movable squeegee; if the second squeegee is located a third position in contact with the to-be-cleaned surface, when the moving distance reaches the first distance and before controlling the cleaning device to move in the direction close to the user, the method further includes: controlling the second squeegee to be lifted up to a fourth position, so that the second squeegee is not in contact with the to-be-cleaned surface.

[0035] By setting the second squeegee to be lifted up, the dead zone between the second squeegee and the rolling brush is eliminated, thereby reducing the residual stains and other impurities in the dead zone. And the impurities attached to the second squeegee can also be shaken off when the second squeegee is lifted up, thereby reducing the possibility of residual impurities on the second squeegee falling down and re-polluting the to-be-cleaned surface after the stains on the floor are cleaned.

[0036] In an embodiment of the present application, the method further includes: if the first squeegee is in the second position which is not in contact with the to-be-cleaned surface, controlling the first squeegee to descend to the first position, so that the first squeegee is in contact with the to-be-cleaned surface; controlling the cleaning device to move in a direction close to the user, and when the moving distance reaches at least a fourth distance, controlling the first squeegee to be lifted up to the second position; where the fourth distance is less than or equal to the first distance; and controlling the cleaning device to move in the direction away from the user, and stop moving when the moving distance reaches at least the first distance.

[0037] When the cleaning task is finished while the first squeegee in a lifting state, if the rolling brush cannot touch the front end of the floor brush due to the obstruction of the obstacles, the first squeegee can be driven to descend and be in contact with to-be-cleaned surface. Then, the impurities in the area which cannot be touched by the rolling brush can be collected by pulling the first squeegee backwards, the first squeegee can be lifted after collection so as to eliminate the dead zone between the first squeegee and the rolling brush, and the floor brush can be controlled to move forward again to clean up the collected impurities, thereby improving the cleaning effect of the cleaning device.

[0038] Optionally, if the first squeegee is located at a second position which is not in contact with the to-be-cleaned surface, controlling the first squeegee to descend to the first position, so that after the first squeegee is in contact with the to-be-cleaned surface, the method further includes: controlling the cleaning device to move in the direction close to the user, and when the angle between the machine body and the to-be-cleaned surface reaches 70-100 degrees, controlling the first squeegee to be lifted up to the second position, then controlling the cleaning device to move in the direction away from the user, and stop moving when the moving distance reaches at least the first distance.

[0039] If the first squeegee is not in contact with the floor when the cleaning device is cleaning, since the angle between the machine body and the to-be-cleaned surface is usually less than 70-100 degrees when cleaning, so that after shutdown, it will be recycled by the user to a user body side at 70-100 degrees. During the recycling process, the rolling brush may leave residual stains and other impurities on the to-be-cleaned surface during the pulling process. In order to reduce the secondary pollution of the cleaned area caused by the impurities, the first squeegee can be controlled to descend and contact the to-be-cleaned surface, so that the stains and other impurities during the pulling process are all collected together by the first squeegee. Then, by lifting the first squeegee up, the cleaning device can actively move forward to clean the residual impurities in the dead zone between the first squeegee and the rolling brush, improving the cleaning effect on the floor.

[0040] In an embodiment of the present application, the machine body is further provided with a second squeegee which is provided at a rear side of the rolling brush and in contact with the to-be-cleaned surface; after controlling the cleaning device to move in the direction close to the user, the method further includes: when the moving distance reaches at least a second distance, controlling the first squeegee to be lifted up, where the second distance is a minimum distance from a contact point of the rolling brush with the to-be-cleaned surface to a contact point of the second squeegee with the to-be-cleaned surface; and controlling the cleaning device to move in the direction away from the user, and stop moving when the moving distance reaches at least the first distance.

[0041] Similar to the previous embodiment, also in the case where the first squeegee is not in contact with the floor, if the second squeegee that contacts the floor is provided behind the rolling brush, the backward pulling distance of the first squeegee needs to be controlled to at least reach the distance between the second squeegee and the rolling brush, so as to at least clean the dead zone gap between the second squeegee and the rolling brush, and then, the dead zone gap between the first squeegee and the rolling brush is cleaned, thereby realizing the shutdown effect with no residual stains.

[0042] In an embodiment of the present application, the second squeegee is a movable squeegee; if the second squeegee is located at a third position which is in contact with the to-be-cleaned surface, when controlling the first squeegee to descend to the first position, the method further includes: controlling the second squeegee to be lifted up to a fourth position, so that the second squeegee is not in contact with the to-be-cleaned surface.

[0043] On the basis of the above embodiment, if the second squeegee is movable, the second squeegee is lifted up before moving backwards, so that the dead zone between the second squeegee and the rolling brush can be eliminated, it is beneficial for the rolling brush to clean the impurities in this area when moving backwards. At the same time, the residual stains and other impurities on the second squeegee will be shaken off when being lifted, thereby reducing the possibility of residual impurities on the second squeegee falling down and re-polluting the to-be-cleaned surface after shutdown, and improving the cleaning effect of the cleaning device.

[0044] In an embodiment of the present application, before controlling the first squeegee to be lifted up to the second position, the method further includes: maintaining the first squeegee at the first position which is in contact with the to-be-cleaned surface, and controlling the cleaning device to move in a direction close to the user; and when the moving distance reaches at least a fifth distance, controlling the first squeegee to be lifted up to the second position, where the fifth distance is less than the first distance.

[0045] If the first squeegee is already in a state of contacting with the to-be-cleaned surface during shutdown, the first squeegee can be pulled backwards while maintaining this state, to achieve the collection of the stains and other impurities between the first squeegee and the rolling brush. Then, the dead zone gap can be eliminated by lifting the first squeegee up, and the residual impurities on the first squeegee can be shaken off to the impurity collection area by means of a lifting action, and finally, the cleaning device cleans up the collected impurities by means of actively moving forward, thereby reducing the residual stains and other impurities, and improving the cleaning effect of the cleaning device.

[0046] In an embodiment of the present application, the machine body is further provided with a second squeegee which is provided at a rear side of the rolling brush and in contact with the to-be-cleaned surface; after controlling the cleaning device to move in the direction close to the user, the method further includes: when the moving distance reaches at least a second distance, controlling the first squeegee to be lifted up to the second position, where the second distance is a minimum distance from a contact point of the rolling brush with the to-be-cleaned surface to a contact point of the second squeegee with the to-be-cleaned surface.

[0047] The present embodiment is similar to the previous embodiment, with the difference being the addition of a second squeegee, and thus it is necessary to add the cleaning of the residual impurities in the gap between the rolling brush and the second squeegee correspondingly, so as to improve the cleaning effect of the cleaning device.

[0048] In an embodiment of the present application, the second squeegee is a movable squeegee; if the second squeegee is located at a third position in contact with the to-be-cleaned surface, when controlling the first squeegee to descend to the first position, the method further includes: controlling the second squeegee to be lifted up to a fourth position, so that the second squeegee is not in contact with a to-be-cleaned surface.

[0049] In the present embodiment, on the basis of the above embodiment, the second squeegee in fixed contact with the floor is adjusted to be a movable second squeegee, so that when cleaning the impurities in the dead zone gap between the second squeegee and the rolling brush, the dead zone gap can be eliminated by the action of lifting up the second squeegee. Compared to the fixed contact with the floor in the above embodiment, the cleaning effect after being lifted up is better.

[0050] Optionally, the floor brush is further provided with a power-assisting wheel, where the power-assisting wheel is provided at the rear side of the rolling brush; the controlling the cleaning device to move in the direction away from the user, including: controlling the rolling brush and / or the power-assisting wheel to rotate in a first direction so as to enable the cleaning device to move in the direction away from the user.

[0051] Optionally, the floor brush is further provided with a power-assisting wheel, and the power-assisting wheel is provided at the rear side of the rolling brush; and the controlling the cleaning device to move in the direction close to the user, including: controlling the rolling brush and / or the power-assisting wheel to rotate in a second direction so as to enable the cleaning device to move in the direction close to the user.

[0052] The above-mentioned power-assisting wheel can assist the cleaning device to move, and certainly, the rolling brush itself also belongs to a power device and its rotation can also drive the cleaning device to move. In some embodiments, after the stop instruction is obtained, the rotating speed of the rolling brush can be increased to be greater than that in the normal cleaning state, so that the cleaning device can move in an intended direction. Certainly, it can also be controlled by the cooperation of the power-assisting wheel and the rolling brush, for example, both of them can be controlled to rotate in one direction so as to achieve a better movement of the cleaning device.

[0053] In a second aspect, the present application provides a control method for a cleaning device, and the cleaning device includes a machine body and a handle connected to a rear side of the body, where the handle is configured to be gripped in hand by a user, a floor brush is connected to a lower end of the machine body, the floor brush is provided with a movable second squeegee and a rolling brush, and the second squeegee is provided at a rear side of the rolling brush; and the method includes: receiving a stop instruction triggered by the user; if the second squeegee is located a third position which is in contact with a to-be-cleaned surface, controlling the second squeegee to be lifted up to a fourth position, so that the second squeegee is not in contact with the to-be-cleaned surface; and controlling the cleaning device to move in a direction close to the user, and stop moving when a moving distance reaches at least a second distance; where the second distance is a minimum distance from a contact point of the rolling brush with the to-be-cleaned surface to a contact point of the second squeegee with the to-be-cleaned surface.

[0054] When the cleaning device only has the movable second squeegee, since the dead zone area can be formed only when the second squeegee falls down, that is, the dead zone area is the to-be-cleaned surface corresponding to the gap between the rolling brush and the second squeegee. Therefore, during shutdown, it is only necessary to lift up the second squeegee and move the cleaning device backwards so as to eliminate the dead zone gap and clean the to-be-cleaned surface corresponding to the dead zone. The control method is simple, which reduces the possibility of residual stains, and improves the cleaning effect of the cleaning device.

[0055] In a third aspect, the present application provides a control method for a cleaning device, and the cleaning device includes a machine body and a handle connected to a rear side of the machine body, where the handle is configured to be gripped in hand by a user, a floor brush is connected to a lower end of the machine body, the floor brush is provided with a movable first squeegee and a rolling brush, and the first squeegee is provided at a front side of the rolling brush; and the method includes: receiving a stop instruction triggered by the user; if the first squeegee is located at a first position which is in contact with a to-be-cleaned surface, controlling the cleaning device to move in a direction close to the user; when a moving distance reaches at least a sixth distance, controlling the first squeegee to be lifted up to a second position; controlling the cleaning device to move in a direction away from the user, and stop moving when the moving distance reaches at least the first distance; the first distance is a minimum distance from a contact point of the rolling brush with the to-be-cleaned surface to a contact point of the first squeegee with the to-be-cleaned surface; where the first distance is greater than the sixth distance.

[0056] Since the movable first squeegee is in a state of contacting with the to-be-cleaned surface during shutdown, the movable first squeegee can be pulled backwards while maintaining this state, and in this way, the stains and other impurities between the first squeegee and the rolling brush can be collected. Then, the dead corner gap is eliminated lifting the first squeegee up, and the residual impurities on the first squeegee can be shaken off to the impurity collection area by means of a lifting action, and finally, the cleaning device cleans up the collected impurities by means of actively moving forward, thereby reducing the residual stains and other impurities, and improving the cleaning effect of the cleaning device.

[0057] In an embodiment of the present application, the machine body is further provided with a second squeegee which is provided at a rear side of the rolling brush and in contact with the to-be-cleaned surface; after controlling the cleaning device to move in a direction close to the user, the method further includes: when the moving distance reaches at least a second distance, controlling the first squeegee to be lifted up to a second position, where the second distance is a minimum distance from a contact point of the rolling brush with the to-be-cleaned surface to a contact point of the second squeegee with the to-be-cleaned surface.

[0058] In an embodiment of the present application, the second squeegee is a movable squeegee; if the second squeegee is located at a third position in contact with the to-be-cleaned surface, when controlling the first squeegee to descend to the first position, the method further includes: controlling the second squeegee to be lifted up to a fourth position, so that the second squeegee is not in contact with the to-be-cleaned surface.

[0059] In a fourth aspect, the present application provides a control method for a cleaning device, and the cleaning device includes a machine body and a handle connected to a rear side of the machine body, where the handle is configured to be gripped in hand by a user, a floor brush is connected to a lower end of the machine body, and a front side of the floor brush is provided with a steam nozzle so that steam can be sprayed to the to-be-cleaned surface; the method includes: receiving a stop instruction triggered by a user; controlling the cleaning device to stop spraying steam; and controlling the cleaning device to move in a direction away from the user, and stop moving when a moving distance reaches at least a seventh distance.

[0060] In an embodiment, in the prior art, in order to solve the problem of recalcitrant stains, the front side of the floor brush of the floor scrubber is provided with a steam nozzle, and the recalcitrant stains are melted by spraying steam, and the method does play a certain role in cleaning recalcitrant stains to some extent.

[0061] However, as a result, since the steam outlet tends to face towards the to-be-cleaned surface, it is inevitable that some steam may experience dripping of condensed liquid at the beginning or end, which in turn increases the risk of residual stains.

[0062] At the same time, it can be conceived that the users usually pull the floor scrubber close to themselves after pressing the stop button, thereby retracting the floor scrubber. However, the steam nozzle is provided at the front side of the floor brush, therefore, after the steam nozzle drips the stains, or after the stains remain in the area between the spraying outlet and the rolling brush, it is difficult for the users to observe them at first during shutdown. At the same time, according to behavioral habits, the users will only find the residue when they pull the floor scrubber towards themselves. Secondly, when the users want to clean again, they can only push the floor scrubber forward again or turn on the floor scrubber again for targeted cleaning the stains, so that the experience and visual perception are very poor.

[0063] Through the present solution, the movement of the cleaning device can be utilized, that is, the cleaning device is controlled to move according to the stop instruction after the steam is sprayed, so that the position where the condensed liquid from the steam nozzle drips can be cleaned once again, thereby solving the problem of the residual stains.

[0064] In other words, the present solution not only can solve the problem of remaining recalcitrant stains, but also can ensure that the stains are not left behind.

[0065] Certainly, both the first squeegee and the steam nozzle may also be integrated on the front side of the floor brush, so that not only the recalcitrant stains can be cleaned, but also ensure that the residual stains during the cleaning process can be solved, and then the stains caused by the steam nozzle and / or the first squeegee itself can be cleaned in cooperation with the movement of the cleaning device.

[0066] In an embodiment of the present application, the seventh distance is configured to be a maximum distance from a contact point of the rolling brush with the to-be-cleaned surface to a front spraying range of the steam nozzle.

[0067] In an embodiment of the present application, the seventh distance is configured to be a circumference length of the rolling brush, such as 160-220mm.

[0068] Similar to the embodiment of the first aspect, in the present embodiment, there are two ways to define the moving distance that the cleaning device can move forward to clean stains, that is, it is defined by the distance between the rolling brush of the cleaning device itself and the farthest spraying end, or it is defined by the length of the circumference corresponding to the rotation angle of the rolling brush, thereby increasing the universality of the control method on different cleaning devices.

[0069] In an embodiment of the present application, the floor brush is further provided with a movable first squeegee which is provided at a front side of the steam nozzle; after receiving the stop instruction triggered by the user and before controlling the cleaning device to move in the direction away from the user, the method further includes: if the first squeegee is located at a first position which is in contact with the to-be-cleaned surface, controlling the first squeegee to be lifted up to a second position, so that the first squeegee is not in contact with the to-be-cleaned surface.

[0088] The exemplary embodiments will be described in detail herein, with examples thereof shown in the accompanying drawings. When the following description refers to the accompanying drawings, unless otherwise indicated, the same reference numbers in different drawings represent the same or similar elements. The implementations described in the following exemplary embodiments do not represent all implementations that are consistent with the present application. On the contrary, they are merely examples of apparatus and methods consistent with some aspects of the present application, and not all embodiments. All other embodiments obtained by the person ordinary skilled in the art based on the embodiments of the present invention without creative efforts shall belong to the protection scope of the present invention.

[0089] Nowadays, more and more households are using a cleaning device, especially a representative floor scrubber therein, which has characteristics of convenient operation and strong stain cleaning capability. However, in more and more use processes, it can be found that there are still problems in the current floor scrubber, such as the problem of residual stains. Specifically, since a rolling brush is wet, there will always be lots of residual stains on a to-be-cleaned surface.

[0090] Based on the above-mentioned technical problem, some floor scrubbers are provided with a movable front squeegee, and the front squeegee is controlled to be in contact with the to-be-cleaned surface during cleaning and push-pull operation, so that residual stains can be cleaned synchronously during the cleaning process.

[0091] Referring to FIG. 3, the front squeegee is a first squeegee 301, and during the process of pulling it backwards, the first squeegee 301 is in contact with the to-be-cleaned surface, so as to clean the residual stains.

[0092] Please continue to refer to FIG. 3, there is a gap L1 at a contact position between the first squeegee 301 and a bottom of the rolling brush 302. Since the first squeegee 301 itself is used to clean the stains and other stains, the residual liquid is easy to drop from a position of the first squeegee itself and the rolling brush 302 in the gap L1 after shutdown.

[0093] Furthermore, in conjunction with the position of the first squeegee 301, which is located at the front side of the floor brush, it is difficult for the users to observe the actual residue. At the same time, after shutdown, the users are accustomed to pulling the floor scrubber backwards so as to retract the floor scrubber, therefore, the residual stains in the above gap L1 are even more difficult to notice or clean, and are often only found by the users after retracting the floor scrubber. And for this purpose, other cleaning actions need to be taken, which increases the labor intensity, and also makes the user experience poor.

[0094] Please continue to refer to FIG. 3, the floor scrubber also includes a second squeegee 303, and there is also a gap L2 at a contact position between the second squeegee 303, the rolling brush and the to-be-cleaned surface. The gap is located at a lower end position of the floor brush, which is more difficult for the users to find, so that this position is easy to be a dead zone, and easy to leave the residual stains.

[0095] During shutdown, the squeegee is firstly retracted to eliminate the dead zone gap, and then is actively moved to the stain area before the dead zone gap is eliminated so as to clean the stains. And finally, a shutdown operation is performed, so that the cleaning of the stains in the dead zone can be realized, aiming to solve the above-mentioned technical problem in the prior art.

[0096] The cleaning device of the present application takes a floor scrubber as an example. In the following embodiments, a preset advancing direction X, a preset moving direction Y and a length direction Z that intersect with each other are introduced. A substantially flat floor is used as a reference object of the to-be-cleaned surface, the preset advancing direction X is substantially parallel to the to-be-cleaned surface, i.e., a substantially horizontal moving direction of the floor brush, the preset moving direction Y is substantially perpendicular to the to-be-cleaned surface, i.e., a direction substantially parallel to a height of the floor brush, the length direction Z is substantially parallel to the length direction of the entire floor brush, and the length direction Z is also substantially parallel to the to-be-cleaned surface.

[0097] FIG. 1 is a schematic overall structural diagram of a floor scrubber provided in an embodiment of the present application; and FIG. 2 is a schematic partial structural diagram of a floor brush provided in an embodiment of the present application. As shown in FIG. 1-FIG. 2, the floor scrubber includes a machine body 100 and a handle 200 connected to a rear side of the machine body 100, where the handle 200 is configured to be gripped in hand by a user. A floor brush 300 is connected to a lower end of the machine body 100, the floor brush 300 is provided with a movable first squeegee 301 and a rolling brush 302, and the first squeegee 301 is provided at a front side of the rolling brush 302, so that when the floor scrubber is stopped, during a process that the handle 200 is pulled backwards and moved vertically by the user, the first squeegee 301 can be used to collect the residual stains during the backward movement. After the impurities such as the stains are collected, the first squeegee 301 is controlled to move so as to eliminate a dead zone stain area on the floor of the gap between the first squeegee 301 and the rolling brush 302, and then the rolling brush 302 is controlled to move forwards, so as to enable the rolling brush 302 to clean the stains on the original dead zone stain area.

[0098] FIG. 3 is a schematic partial cross-sectional structural diagram of a floor brush provided in an embodiment of the present application. Referring to FIG. 3, the rolling brush 302 is rotatably connected to a front end of the floor brush 300. The first squeegee 301 is provided at the front side of the rolling brush 302 along the preset advancing direction X. A first driving assembly and a first transmission assembly are further provided inside the floor brush 300, where one end of the first transmission assembly is connected to the first driving assembly and the other end of the first transmission assembly is connected to the first squeegee 301, and the first driving assembly is in transmission connection with the first squeegee 301 through the first transmission assembly.

[0099] The first driving assembly can drive the first transmission assembly to move along the length direction Z, and during a movement process of the first transmission assembly, the first squeegee 301 can be synchronously driven to move close to or away from the to-be-cleaned surface 400 along the preset moving direction Y, so that the first squeegee 301 moves towards the to-be-cleaned surface 400 along the preset movement direction Y and reaches a first position which is in contact with the to-be-cleaned surface 400, or moves away from the to-be-cleaned surface 400 along the preset movement direction Y and reaches a second position which is not in contact with the to-be-cleaned surface 400.

[0100] It should be noted that, please continue to refer to FIG. 3, the rolling brush 302 has a central axis O and a central section α. The central axis O is located on the central section α, and the central section α is perpendicular to the preset advancing direction X. It should be understood that, in the present embodiment, the rolling brush 302 is a cylindrical rolling brush 302, the central axis O corresponds to a central axis O of the cylindrical rolling brush 302, and at least part of the first driving assembly is located on a rear side of the central section α along the preset advancing direction X.

[0101] During the process of the floor brush 300 moving along the preset advancing direction X, the rolling brush 302 can clean and brush the to-be-cleaned surface 400 along the preset advancing direction X. Before the floor brush 300 is pulled backwards, the first driving assembly drives the first transmission assembly to move along the length direction Z of the rolling brush 302, thereby driving the first squeegee 301 to move towards the to-be-cleaned surface 400 and adhere to the to-be-cleaned surface. During the process of pulling the floor brush 300 backwards, the first squeegee 301 scrapes away the dirt on the cleaning surface, which helps to reduce the residual stains on the cleaning surface and improve the cleaning effect of the floor brush 300.

[0102] Please continue to refer to FIG. 3, the floor scrubber further includes a second squeegee 303, where the second squeegee 303 is provided at a rear side of the rolling brush 302 along the preset advancing direction X. A second driving assembly and a second transmission assembly are further provided inside the floor brush 300, where one end of the second transmission assembly is connected to the second driving assembly, the other end of the second transmission assembly is connected to the second squeegee 303, and the second driving assembly is in transmission connection with the second squeegee 303 through the second transmission assembly.

[0103] The second driving assembly can drive the second transmission assembly to move along the length direction Z, and during a movement process of the second transmission assembly, the second squeegee 303 can be synchronously driven to move close to or away from the to-be-cleaned surface 400 along the preset moving direction Y, so that the second squeegee 303 moves towards the to-be-cleaned surface 400 along the preset moving direction Y and reaches a third position which is in contact with the to-be-cleaned surface 400, or moves away from the to-be-cleaned surface 400 along the preset moving direction Y and reaches a fourth position which is not in contact with the to-be-cleaned surface 400.

[0104] Optionally, the second driving assembly can drive the second transmission assembly to rotate, so as to drive one end of the second squeegee 303 to rotate, so that the other end of the second squeegee 303 moves along the length direction Z by means of the rotation action, thereby driving the second squeegee 303 to move towards the to-be-cleaned surface 400 and adhere to the to-be-cleaned surface 400, or to move away from the to-be-cleaned surface 400. During the process of the cleaning device pushing the floor brush 300 forwards, the second squeegee 303 is controlled to adhere to the to-be-cleaned surface 400, so that the second squeegee 303 scrapes away the dirt on the to-be-cleaned surface 400, which helps to reduce the residual stains on the to-be-cleaned surface 400 and improve the cleaning effect of the floor brush 300.

[0105] Please continue to refer to FIG. 1- FIG. 2, the floor scrubber further includes a power-assisting wheel 304 for assisting in driving the floor brush 300 to travel on the to-be-cleaned surface 400.

[0106] In some embodiments, the floor scrubber is further provided with a storage assembly, and a processor and the storage assembly can be provided inside the floor scrubber. Optionally, the storage assembly may be integrated with the processor, or may be two separate components from the processor.

[0107] The storage assembly is configured to store data, such as various software control programs, some modes and / or parameters of the floor scrubber, etc. Specifically, the programs may include program codes which include computer operation instructions.

[0108] The processor may include, for example, one or more circuits or chips with control functions.

[0109] The processor is configured to control the operation of the floor scrubber and respond to user actions through various software control programs stored in a memory.

[0110] The execution subject of the embodiments in the present application may be the processor in the floor scrubber or a server corresponding to the floor scrubber. The server is located in the cloud and is connected to the processor of the floor scrubber through the network, so as to issues control instructions to the floor scrubber or forward the control instruction sent by the user through a terminal device to the floor scrubber, etc.

[0111] Taking the processor in the floor scrubber as the execution subject as an example, the technical solution of the present application and how to solve the above technical problem through the technical solution of the present application will be described in detail herein through specific embodiments. The following several specific embodiments may be combined with each other, and the same or similar concepts or procedures may not be repeated in certain embodiments.

[0112] FIG. 4 is a schematic flowchart of a control method for a cleaning device with a movable first squeegee provided in an embodiment of the present application. Referring to FIG. 4, the method includes the following steps.

[0113] S401, receiving a stop instruction triggered by a user.

[0114] The stop instruction triggered by the user may be in various manners. For example, when a control button is provided on the cleaning device, the user triggers the processor of the cleaning device to generate the stop instruction by directly controlling the button on the cleaning device. Alternatively, a voice recognition module is provided on the cleaning device, and the user triggers a processor voice recognition module of the cleaning device through voice control so as to generate the stop instruction. Alternatively, a communication module is provided on the cleaning device, the cleaning device is connected to a third party terminal device through the communication module for sending a stop request to the cleaning device through the third party terminal device, and the cleaning device triggers the processor of the cleaning device to generate the stop instruction according to the stop request.

[0115] S402, determining whether a first squeegee is in contact with a to-be-cleaned surface; if so, executing S403-S404; and if not, executing S405-S407.

[0116] S403, controlling the first squeegee to be lifted up to a second position, so that the first squeegee is not in contact with the to-be-cleaned surface.

[0117] By lifting up the first squeegee, the dead zone gap can be eliminated, and at the same time, the rolling brush can conveniently enter the to-be-cleaned surface corresponding to the original dead zone gap. In addition, the action of lifting up the first squeegee can also enable the stains and other impurities attached to the first squeegee to fall down, so as to be cleaned together when the cleaning device moves forwards, thereby further improving the cleaning effect of the cleaning device.

[0118] S404, controlling the cleaning device to move in a direction away from the user, and stop moving when a moving distance reaches at least a first distance.

[0119] The moving distance may be determined based on a moving distance of the floor brush, or be determined based on a rotation angle of the rolling brush; or be determined based on a rotation angle of the power-assisting wheel.

[0120] For example, the first distance is configured to be a minimum distance from a contact point of the rolling brush with the to-be-cleaned surface to a contact point of the first squeegee with the to-be-cleaned surface, so that the dirt in the above gap L1 can be cleaned.

[0121] By defining the moving distance of the floor brush to be associated with the distance between the rolling brush and the first squeegee, it is possible to more precisely complete the cleaning of the impurities in the dead zone gap, thereby ensuring that there will be no missed cleaning phenomenon.

[0122] For another example, the first distance is configured to be 1 / 4-3 / 4 of a circumference length of the rolling brush.

[0123] By defining the moving distance of the floor brush to be associated with the circumference of the rolling brush, the moving distance can be indirectly controlled by simply controlling the rotation angle of the rolling brush. The control method is simpler and is applicable to cleaning devices in different models and rolling brushes in different sizes, thereby ensuring that the cleaning moving distance satisfies the length of the dead zone and improving the cleaning effect of the cleaning device.

[0124] By means of the above-mentioned methods, a cleaning minimum area can be accurately controlled to cover all dead zones, thereby ensuring that residual stains can be cleaned away.

[0125] A liquid separator and a wiper strip are provided inside the floor brush 300, where the liquid separator is used for supplying liquid to the rolling brush so as to keep the rolling brush in a wet state, and the liquid separator is generally provided at a rear side of the rolling brush 302 so as to supply liquid to the rolling brush 302.

[0126] The wiper strip is configured to squeeze liquid from the rolling brush 302, a position of the wiper strip is also generally located at the rear side of the rolling brush 302, and is kept at a certain interference amount with the rolling brush 302, so as to squeeze liquid from the rolling brush 302.

[0127] A suction device (not shown) is also provided inside the machine body 100. The suction device may be a suction motor. When the cleaning device moves in the direction away from the user, the liquid separator is controlled to stop supplying liquid, and the suction device is maintained in a suction state, so that the rolling brush 302 can absorb the stains on the to-be-cleaned surface during the movement process of the cleaning device.

[0128] After obtaining the stop instruction, the liquid separator is controlled to no longer provide liquid, and at the same time, the liquid-squeezing capacity of the wiper strip is utilized, and the suction device is controlled to suck, so that the liquid content of the rolling brush 302 can be prevented from being in a saturated state, thus the stains on the to-be-cleaned surface can be further absorbed by controlling the rolling brush to move in the direction away from the user.

[0129] Optionally, when the cleaning device moves in the direction away from the user, a suction force of the suction device is controlled to be greater than or equal to 10000 Pa.

[0130] The suction device here may be a suction motor. As mentioned above, during the movement process of the cleaning device, the suction force of the suction device is kept greater than or equal to 10000 Pa, so that the liquid content of the rolling brush can be further ensured to be within a reasonable range, thereby enhancing the ability to clean residual stains.

[0131] In an embodiment, the wiper strip is configured to be movable relative to the rolling brush 302, and when the cleaning device moves in the direction away from the user, the wiper strip is controlled to move away from the rolling brush 302, and the suction force of the suction device is controlled to be greater than or equal to 10000 Pa.

[0132] S405, controlling the first squeegee to descend to a first position, so that the first squeegee is in contact with the to-be-cleaned surface.

[0133] S406, controlling the cleaning device to move in a direction close to the user, and when a moving distance reaches at least a fourth distance, controlling the first squeegee to be lifted up to the second position.

[0134] The fourth distance is less than or equal to the first distance.

[0135] After the first squeegee is in contact with the to-be-cleaned surface, during the process of pulling it backwards, the stains and other impurities are all collected together by the first squeegee, and the first squeegee is lifted after collection, so as to eliminate the dead zone between the first squeegee and the rolling brush, and the floor brush is controlled to move forward again, so as to clean up the collected impurities.

[0136] S407, controlling the cleaning device to move away from the user, and stop moving when the moving distance reaches at least the first distance.

[0137] In the present embodiment, the squeegee is pulled backwards to collect the stains and other impurities in the area where the backward pulling path is located, and the first squeegee is lifted up, the dead zone gap between the first squeegee and the rolling brush can be eliminated, and then the floor brush is controlled to actively move forwards in the direction away from the user, so as to clean up the impurities in the corresponding area of the original dead zone gap, thereby improving the stain cleaning effect. Furthermore, according to the distance between the first squeegee and the rolling brush, the moving distance can be defined more precisely.

[0138] After receiving the stop instruction triggered by the user, if the first squeegee is located at a first position which is in contact with the to-be-cleaned surface, the cleaning device is controlled to move in a direction close to the user; when the moving distance reaches at least a sixth distance, the first squeegee is controlled to be lifted up to a second position; and the cleaning device is controlled to move in the direction away from the user, and stop moving when the moving distance reaches at least the first distance; the first distance is a minimum distance from a contact point of the rolling brush with the to-be-cleaned surface to a contact point of the first squeegee with the to-be-cleaned surface; where the first distance is greater than the sixth distance.

[0139] Since the first movable squeegee is in a state of contacting with the to-be-cleaned surface during shutdown, the first movable squeegee can be pulled backwards while maintaining this state, so as to achieve the collection of stains and other impurities between the first squeegee and the rolling brush. Then, it can be lifted up to eliminate the dead zone gap, and the residual impurities on the first squeegee can be shaken off to the impurity collection area by means of a lifting action, and finally, the cleaning device cleans up the collected impurities by means of actively moving forward, thereby reducing the residual stains and other impurities, and improving the cleaning effect of the cleaning device.

[0140] FIG. 5 is a schematic flowchart of a control method for a cleaning device with a movable first squeegee and a non-movable second squeegee provided in an embodiment of the present application. The second squeegee is provided on the rear side of the rolling brush and is always in contact with the to-be-cleaned surface. As shown in FIG. 5, the method includes the following steps.

[0141] S501, receiving a stop instruction triggered by a user.

[0142] S502, determining whether a first squeegee is in contact with a to-be-cleaned surface; if so, executing S503-S505; and if not, executing S506-S509.

[0143] S503, controlling the first squeegee to be lifted up to a second position, so that the first squeegee is not in contact with the to-be-cleaned surface.

[0144] S504, controlling the cleaning device to move in a direction away from the user.

[0145] S505, when a moving distance reaches a first distance, controlling the cleaning device to move in a direction close to the user and stop moving when the moving distance reaches at least a third distance.

[0146] The moving distance may be determined based on a moving distance of the floor brush, or be determined based on a rotation angle of the rolling brush; or be determined based on a rotation angle of the power-assisting wheel.

[0147] For example, the first distance is configured to be a minimum distance from a contact point of the rolling brush with the to-be-cleaned surface to a contact point of the first squeegee with the to-be-cleaned surface.

[0148] For another example, the first distance is configured to be 1 / 4-3 / 4 of a circumference length of the rolling brush.

[0149] Exemplarily, the third distance is configured to be a sum of the first distance and a second distance, and the second distance is configured to be a minimum distance from a contact point of the rolling brush with the to-be-cleaned surface to a contact point of the second squeegee with the to-be-cleaned surface.

[0150] Exemplarily, when the cleaning device moves in the direction close to the user by at least the third distance, an angle between a side of the machine body facing towards the user and the to-be-cleaned surface is between 70 degrees and 100 degrees.

[0151] Since the cleaning device needs to be stored upright after stopping cleaning, that is, the angle between the machine body and the to-be-cleaned surface is between 70 degrees and 100 degrees, the cleaning device can be stored while actively cleaning the residual stains.

[0152] S506, controlling the first squeegee to descend to a first position, so that the first squeegee is in contact with the to-be-cleaned surface.

[0153] S507, controlling the cleaning device to move in the direction close to the user.

[0154] S508, when the moving distance reaches at least a second distance, controlling the first squeegee to be lifted up to the second position.

[0155] The second distance is a minimum distance from a contact point of the rolling brush with the to-be-cleaned surface to a contact point of the second squeegee with the to-be-cleaned surface.

[0156] S509, controlling the cleaning device to move in the direction away from the user, and stop moving when the moving distance reaches at least the first distance.

[0157] In the present embodiment, on the basis of controlling the moving distance originally, a control operation corresponding to the backward cleaning of the second squeegee is added according to the provided second squeegee, so that the dead zone gap between the second squeegee and the rolling brush can be cleaned, thereby improving the stain cleaning effect.

[0158] FIG. 6 is a schematic flowchart of a control method for a cleaning device with a movable first squeegee and a movable second squeegee provided in an embodiment of the present application. The second squeegee is provided on a rear side of the rolling brush, and is in movable contact with to-be-cleaned surface or is not contact with the to-be-cleaned surface. As shown in FIG. 6, the method includes the following steps.

[0159] S601, receiving a stop instruction triggered by a user.

[0160] S602, determining whether a first squeegee is in contact with a to-be-cleaned surface; if so, executing S603-S604; if not, executing S604, or executing S609-S611 first and then executing S604.

[0161] S603, controlling the first squeegee to be lifted up to a second position, so that the first squeegee is not in contact with the to-be-cleaned surface.

[0162] S604, determining whether a second squeegee is in contact with the to-be-cleaned surface; if so, executing S605-S607; and if not, executing S608.

[0163] S605, controlling the cleaning device to move in a direction away from the user.

[0164] S606, when a moving distance reaches a first distance, controlling the second squeegee to be lifted up to a fourth position, so that the second squeegee is not in contact with the to-be-cleaned surface.

[0165] The moving distance may be determined based on a moving distance of the floor brush, or be determined based on a rotation angle of the rolling brush; or be determined based on a rotation angle of the power-assisting wheel.

[0166] For example, the first distance is configured to be a minimum distance from a contact point of the rolling brush with the to-be-cleaned surface to a contact point of the first squeegee with the to-be-cleaned surface.

[0167] For another example, the first distance is configured to be 3 / 4 of a circumference length of the rolling brush.

[0168] S607, controlling the cleaning device to stop when moving in a direction close to the user by at least a second distance.

[0169] The second distance is a minimum distance from a contact point of the rolling brush with the to-be-cleaned surface to a contact point of the second squeegee with the to-be-cleaned surface.

[0170] S608, controlling the cleaning device to move in the direction away from the user, and stop moving when the moving distance reaches at least the first distance.

[0171] Exemplarily, when the cleaning device moves in the direction close to the user by at least the third distance, an angle between a side of the machine body facing towards the user and the to-be-cleaned surface is between 70 degrees and 100 degrees.

[0172] S609, controlling the first squeegee to descend to a first position, so that the first squeegee is in contact with the to-be-cleaned surface.

[0173] S610, controlling the cleaning device to move in the direction close to the user.

[0174] S611, controlling the first squeegee to be lifted up to the second position when the moving distance reaches at least the second distance.

[0175] The second distance is a minimum distance from a contact point of the rolling brush with the to-be-cleaned surface to a contact point of the second squeegee with the to-be-cleaned surface.

[0176] In the present embodiment, the second squeegee in the above embodiment is configured to be a movable second squeegee, so that when the dead zone gap between the second squeegee and the rolling brush is cleaned, the contact condition between the second squeegee and the to-be-cleaned surface can be controlled so as to further reduce the residual stains in the dead zone gap and improve the cleaning effect of the cleaning device. The beneficial effects of other steps are similar to those of steps S401 to S407, and will not be repeated in the present embodiment.

[0177] FIG. 7 is a schematic flowchart of another control method for the cleaning device with the movable first squeegee according to the embodiment of the present application. Referring to FIG. 7, optionally, on the basis of the above embodiments, before performing S403 or S503 or S603, if the first squeegee is at the first position which is in contact with the to-be-cleaned surface, the following steps may further be performed.

[0178] S701, maintaining the first squeegee at the first position which is in contact with the to-be-cleaned surface, and controlling the cleaning device to move in a direction close to the user.

[0179] S702, when a moving distance reaches at least a fifth distance, controlling the first squeegee to be lifted up to a second position.

[0180] The fifth distance is less than the first distance.

[0181] In the present embodiment, the first squeegee which has been in contact with the to-be-cleaned surface is utilized to collects stains and other impurities in a previous gap formed by the first squeegee and the rolling brush. Therefore, when the first squeegee moves forwards after collection, because it has retreated and then moved forward, the collected impurities will not be unable to be cleaned due to the inability to continue moving forward, thereby ensuring that the impurities can be completely cleaned, and improving the cleaning effect of the cleaning device.

[0182] FIG. 8 is a schematic flowchart of a control method of a cleaning device with a steam nozzle provided in an embodiment of the present application. The steam nozzle is provided at a front side of the floor brush, so that steam can be sprayed to the to-be-cleaned surface; a movable first squeegee is further provided on the floor brush, and the first squeegee is provided at a front side of the steam nozzle; a second squeegee is further provided on the floor brush, and the second squeegee is provided on the rear side of the rolling brush and is in contact with the to-be-cleaned surface. Referring to FIG. 8, the method includes the following steps.

[0183] S801, receiving a stop instruction triggered by a user.

[0184] S802, controlling the cleaning device to stop spraying steam.

[0185] S803, determining whether a first squeegee is in contact with a to-be-cleaned surface; if so, executing S804-S806; and if not, executing S805-S806.

[0186] S804, controlling the first squeegee to be lifted up to a second position, so that the first squeegee is not in contact with the to-be-cleaned surface.

[0187] S805, controlling the cleaning device to move in a direction away from the user.

[0188] The moving distance may be determined based on a moving distance of the floor brush, or be determined based on a rotation angle of the rolling brush; or be determined based on a rotation angle of the power-assisting wheel.

[0189] For example, the seventh distance is configured to be a maximum distance from a contact point of the rolling brush with the to-be-cleaned surface to a front spraying range of the steam nozzle.

[0190] As another example, the seventh distance is configured to be a circumference length of the rolling brush.

[0191] S806, when a moving distance reaches a seventh distance, controlling the cleaning device to move in a direction close to the user, and stop moving when the moving distance reaches at least a second distance.

[0192] The second distance is a minimum distance from a contact point of the rolling brush with the to-be-cleaned surface to a contact point of the second squeegee with the to-be-cleaned surface.

[0193] Optionally, if the second squeegee which is in contact with the to-be-cleaned surface is movable, after performing S805, the following steps may be further performed.

[0194] S807, controlling the second squeegees to be lifted up to a fourth position, so that the second squeegee is not in contact with the to-be-cleaned surface.

[0195] S808, controlling the cleaning device to move in a direction close to the user by the second distance.

[0196] In the present embodiment, on the basis of the above-mentioned embodiments, the steam nozzle is added to the cleaning device, and because the stains will be formed after the newly added steam nozzle sprays liquid, it is necessary to control the moving direction and moving distance accordingly so as to clean the stains in the liquid-sprayed area, thereby improving the cleaning effect of the cleaning device. The beneficial effects of other steps are similar to those of steps S401 to S407, and will not be repeated in the present embodiment.
