Description

Technical Field

[0001] The present application relates to the field of cleaning, and more particularly, to a control method for a cleaning system. Background Art

[0002] Cleaning devices usually have a liquid supply component and a sewage suction component, which can simultaneously perform sweeping and mopping on the surface to be cleaned. The cleaning parts of the cleaning device are usually rotatably installed in a semi-open roller brush cavity to wipe the surface to be cleaned by rotation. Single cleaning methods may have problems such as incomplete cleaning of heavy dirt and water stains remaining on the ground.

[0003] In the prior art, to improve the problem of water stains remaining on the ground, a movable front squeegee is provided on the front side of the roller brush, and the position of the front squeegee is adjusted by detecting the moving direction of the cleaning device. When the cleaning device moves forward, the front squeegee is separated from the surface to be cleaned, and when the cleaning device moves backward, the front squeegee abuts against the surface to be cleaned, thereby reducing the water stains remaining on the ground when the cleaning device moves backward.

[0004] However, the environment of the surface to be cleaned faced by the existing cleaning devices during cleaning operations is relatively complex. Adjusting the position of the front squeegee only according to the moving direction of the cleaning device cannot completely solve the problems of ground dirt and water stains remaining. Summary of the Invention

[0005] The purpose of the present application is to provide a control method for a cleaning system, which can improve the cleaning effect of the cleaning system.

[0006] In a first aspect, an embodiment of the present application provides a control method for a cleaning system. The cleaning system includes a cleaning machine, which includes a handle, a body, a floor brush pivotally connected to the body, and a detection unit for detecting the operating state of the floor brush. The floor brush is provided with a cleaning part and a movable front squeegee on the front side of the cleaning part. The control method of the cleaning system includes: obtaining the operating state of the floor brush detected by the detection unit, and the operating state of the floor brush at least includes the operating speed of the floor brush; controlling the front squeegee to be in an abutting state or a separated state with the surface to be cleaned according to the operating state of the floor brush.

[0007] Compared with the related art, in the control method of the cleaning system provided by the embodiments of the present application, the detection unit detects the operating state of the floor brush, and controls the front squeegee to be in a contact state or a separated state with the surface to be cleaned according to the operating state of the floor brush. When the front squeegee is in contact with the surface to be cleaned, not only can the dirt and water stains on the surface to be cleaned be scraped off, but also since the squeegee is arranged on the front side of the cleaning member, when the front squeegee is in contact with the surface to be cleaned, it can play a certain sealing effect on the dirt suction cavity in the cleaning member from the front side, improving the suction capacity; when the front squeegee is in a separated state from the surface to be cleaned, the resistance received by the user when operating the cleaning machine can be reduced; since the operating state of the floor brush detected by the detection unit in the present application includes the operating speed of the floor brush, compared with the prior art that only controls the lifting of the squeegee according to the movement direction of the floor brush, controlling the front squeegee to be in a contact state or a separated state with the surface to be cleaned according to the operating speed of the floor brush can further subdivide and specifically process more different application scenarios, making the contact state or separated state of the front squeegee with the surface to be cleaned more adaptable to different application scenarios and improving the cleaning effect.

[0008] In an alternative embodiment, the controlling the front squeegee to be in a contact state or a separated state with the surface to be cleaned according to the operating state of the floor brush includes: when the operating speed is less than the set speed threshold, controlling the front squeegee to be in a contact state with the surface to be cleaned. The operating speed of the floor brush being less than the set speed threshold indicates that the operating speed of the floor brush is relatively low. The floor brush running at a low speed usually occurs in areas where the surface to be cleaned is heavily soiled. At this time, controlling the front squeegee to be in a contact state with the surface to be cleaned can improve the sealing effect of the dirt suction cavity and the suction capacity, and further improve the cleaning effect of the cleaning machine.

[0009] In an alternative embodiment, the control method of the cleaning system further includes: when the operating speed is greater than or equal to the set speed threshold, controlling the front squeegee to be in a separated state from the surface to be cleaned. The operating speed of the floor brush being greater than or equal to the set speed threshold indicates that the operating speed of the floor brush is relatively high. The front squeegee in contact with the ground under high-speed operation will generate a large resistance, affecting the user's operation of the cleaning machine. At this time, controlling the front squeegee to be in a separated state from the surface to be cleaned can avoid the resistance between the front squeegee and the ground and facilitate the user to operate the cleaning machine.

[0010] In an alternative embodiment, the operating state of the floor brush further includes the running direction of the floor brush. Controlling the front squeegee to be in a contacting state or a separated state with the surface to be cleaned according to the operating state of the floor brush includes: when the running direction is forward decelerated running, controlling the front squeegee to be in a contacting state with the surface to be cleaned. The running direction is forward and decelerated running, indicating that the user's forward pushing process of the cleaning machine is almost over, and the user is about to pull the cleaning machine backward. At this time, controlling the front squeegee to be in a contacting state with the surface to be cleaned, during the subsequent backward pulling process of the cleaning machine, the front squeegee in the contacting state with the surface to be cleaned can scrape off the water stains on the surface to be cleaned, reducing the water stains remaining on the surface to be cleaned during the cleaning process.

[0011] In an alternative embodiment, after controlling the front squeegee to be in a contacting state with the surface to be cleaned, it further includes: when the running direction is backward decelerated or the running direction is backward and the running speed is less than a set speed threshold, or when the front squeegee is in contact with the surface to be cleaned for a preset duration, controlling the front squeegee to switch from the contacting state with the surface to be cleaned to the separated state with the surface to be cleaned. The running direction of the floor brush is backward decelerated, or the running direction is backward and the running speed is less than a set speed threshold, indicating that the user's backward pulling process of the cleaning machine is almost over, and the user is about to push the cleaning machine forward. At this time, controlling the front squeegee to switch from the contacting state with the surface to be cleaned to the separated state with the surface to be cleaned can avoid the resistance between the front squeegee and the ground during the forward pushing process of the cleaning machine, facilitating the user to operate the cleaning machine; or based on the usage habit of the cleaning machine, the user usually operates the cleaning machine to alternately push / pull forward / backward. When the front squeegee is in contact with the surface to be cleaned for a preset duration and the user is about to push the cleaning machine forward, controlling the front squeegee to switch from the contacting state with the surface to be cleaned to the separated state with the surface to be cleaned can also avoid the resistance between the front squeegee and the ground during the forward pushing process of the cleaning machine, facilitating the user to operate the cleaning machine.

[0012] In an alternative embodiment, the cleaning machine further includes a sewage suction system, and the sewage suction system includes a sewage suction motor, a sewage suction pipe, and a sewage bucket. The control method of the cleaning system further includes: when the running direction is forward and the running speed is less than a set speed threshold, controlling the power of the sewage suction motor to decrease. The running direction of the floor brush is forward and the running speed is less than a set speed threshold, indicating that the user intentionally controls the floor brush to move forward at a low speed. At this time, the probability of items such as electrical wires and food kernels that are not suitable for being sucked into the sewage suction pipe appearing near the cleaning machine is relatively high. Controlling the power of the sewage suction motor to decrease can reduce the possibility of items that are not suitable for being sucked into the sewage suction pipe being sucked into the sewage suction pipe, improving the running safety of the cleaning machine.

[0013] In an alternative embodiment, the sewage suction system further includes a foreign object detection device, and the control method of the cleaning system further includes: when the foreign object detection device detects that there is a foreign object in the sewage suction pipe, controlling the cleaning member to switch the rotation direction. Controlling the cleaning member to switch the rotation direction can promptly eject the foreign object in the sewage suction pipe, reducing the possibility of the foreign object blocking the sewage suction pipe or damaging the sewage suction pipe, and improving the user experience and operation safety of the cleaning machine.

[0014] In an alternative embodiment, the detection unit is further configured to detect whether there is an obstacle in front of the floor brush, and the control method of the cleaning system further includes: when the detection unit detects that there is an obstacle in front of the floor brush, controlling the front squeegee to be in contact with the surface to be cleaned. When the detection unit detects that there is an obstacle in front of the floor brush, it indicates that the distance between the floor brush and the obstacle is relatively close. Since the front squeegee is arranged in front of the floor brush, at this time, controlling the front squeegee to be in contact with the surface to be cleaned, the front squeegee that has descended to be in contact with the surface to be cleaned can also be in contact with the obstacle. When the cleaning machine is pulled backward, the front squeegee in contact with the obstacle can drive the dirt that is difficult to be sucked away near the obstacle to retreat, facilitating the subsequent suction of this dirt; in addition, when the floor brush approaches the obstacle, controlling the front squeegee to be in contact with the surface to be cleaned, when the floor brush collides with the obstacle, the front squeegee first collides with the obstacle to absorb energy, reducing the damage caused to the floor brush by the collision between the floor brush and the obstacle.

[0015] In an alternative embodiment, the cleaning system further includes a base for placing the cleaning machine, and the control method of the cleaning system further includes: during the self-cleaning process of the cleaning machine, controlling the front squeegee to be in contact with the base at least once. Controlling the front squeegee to be in contact with the base at least once during the self-cleaning process can not only effectively clean the front squeegee, but also the front squeegee can block the cleaning liquid splashing forward during the self-cleaning process, reducing the liquid splashing during the cleaning process.

[0016] In an alternative embodiment, the cleaning system further includes a base for placing the cleaning machine, and the control method of the cleaning system further includes: during the drying process of the cleaning machine, controlling the front squeegee to be in contact with the base. After controlling the front squeegee to be in contact with the base, the front squeegee can play a certain sealing effect on the sewage suction cavity in the cleaning member from the front side, enabling the drying air flow to flow in the space formed by the cleaning machine and the accommodation groove during the drying process, improving the drying effect.

[0029] It should be noted that: similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0030] In addition, terms such as "first" and "second" are only used for distinguishing descriptions and should not be construed as indicating or implying relative importance.

[0031] It should be noted that, without conflict, the features in the embodiments of the present application can be combined with each other.

[0032] Embodiment 1

[0033] Embodiment 1 of the present application provides a control method for a cleaning system, which is applied to control the cleaning system. As Figure 1 、 Figure 2 shown, the cleaning system may specifically include a cleaning machine 100, and the cleaning machine 100 includes a handle 101, a body 102, a floor brush 103 pivotally connected to the body 102, and a detection unit (not shown in the figure) for detecting the operating state of the floor brush 103. A cleaning member 104 for cleaning the surface to be cleaned 300 and a movable front squeegee 105 disposed on the front side of the cleaning member 104 are provided on the floor brush 103. As Figure 1 shown, the front squeegee 105 can move upward to a separated state from the surface to be cleaned 300, that is, the front squeegee 105 is in a separated state from the surface to be cleaned 300. The surface to be cleaned 300 here may be a floor, a tile surface, a carpet surface, a cement surface, etc., all surfaces that can be cleaned by cleaning equipment. As Figure 2 shown, the front squeegee 105 can also move downward to abut against the surface to be cleaned 300, that is, the front squeegee 105 is in an abutting state with the surface to be cleaned 300.

[0034] In an alternative solution of this embodiment, in Embodiment 1, as Figure 3 shown, the front squeegee 105 is disposed on the roller brush cover 106 of the floor brush 103. The front squeegee 105 has an arc surface portion 1051 disposed on the roller brush cover 106 and a sealing portion 1052 connected to the arc surface portion 1051. When the front squeegee 105 is in an abutting state with the surface to be cleaned 300, the sealing portion 1052 fits with the surface to be cleaned 300 to form a closed space A. Optionally, the front squeegee 105 is detachably installed with the roller brush cover 106 and the material of the front squeegee 105 is a flexible material, which is convenient for the user to replace the front squeegee 105.

[0035] As another alternative embodiment of this embodiment, the front squeegee 105 is disposed on the roller brush cover 106 of the floor brush 103, and the roller brush cover 106 can drive the front squeegee 105 to rotate together so that the front squeegee 105 has an abutting state or a separated state with the surface to be cleaned.

[0036] Furthermore, as Figure 3 、 Figure 4As shown in the figure, in the first embodiment, a movable member 107 is provided on the floor brush 103, and the movable member 107 is movably installed on the floor brush under the action of a driving motor. As Figure 4 shown, when the movable member 107 extends forward, the front scraping strip 105 is in contact with the surface to be cleaned 300; as Figure 3 shown, when the movable member 107 retracts, the front scraping strip 105 is separated from the surface to be cleaned 300.

[0037] Or in some other embodiments of the present application, the front scraping strip may also be provided on the roller brush cover, and may have other structures such as a parallel plane covering the ground of the roller brush cover and an extension surface extending towards the ground. Among them, the parallel plane may be a straight long strip parallel to the ground or an inclined plane that gradually moves away from the ground from the direction close to the roller brush to the direction away from the roller brush and forms a certain inclination angle with the ground. The extension surface protrudes from the plane where the roller brush cover is located, so that the front scraping strip can be close to the wall and the dirt at the place close to the wall is less likely to be squeezed by the front scraping strip and is in a free state, so that the dirt can enter the dirt suction port.

[0038] As Figure 5 shown, the control method of the cleaning system provided in the first embodiment may specifically include the following steps:

[0039] Step S101: Obtain the running state of the floor brush detected by the detection unit.

[0040] In this step, the running state of the floor brush includes at least the running speed of the floor brush 103. In the first embodiment, the running speed of the floor brush 103 is the moving speed when the floor brush 103 moves forward or backward. It can be understood that the running speed of the floor brush 103 being the moving speed when the floor brush 103 moves forward or backward is only an example of the running speed of the floor brush 103 in the first embodiment. In some other embodiments of the present application, for a cleaning machine 100 that can move laterally, the running speed of the floor brush 103 may also be, for example, the moving speed when the floor brush 103 moves laterally.

[0041] Based on the foregoing running speed of the floor brush 103 being the moving speed when the floor brush 103 moves forward or backward, in the first embodiment, the detection unit is a grating detection structure. The detection unit of the grating detection structure may specifically be provided on the support wheel of the floor brush 103. In this step S101, the moving speed of the floor brush 103 may be obtained by the number of rotations of the support wheel of the floor brush 103 detected by the detection unit of the grating detection structure per unit time.

[0042] It can be understood that the detection unit being a grating detection structure is only an example of the structure of the detection unit in the first embodiment. In some other embodiments of the present application, the detection unit may also be, for example, an electromotive force detection structure, a Hall detection structure, or other structures.

[0043] It can be understood that the specific setting of the aforementioned detection unit on the support wheel of the floor brush 103 is also an example of the setting position of the detection unit in the first embodiment of the present invention. In some other embodiments of the present application, the floor brush 103 may include, for example, an auxiliary wheel with a diameter smaller than that of the support wheel and capable of floating up and down, and the detection unit is provided on the auxiliary wheel. Correspondingly, in this step S101, the moving speed of the floor brush 103 can be obtained by the number of rotations of the auxiliary wheel detected by the detection unit of the grating detection structure per unit time. When the surface to be cleaned 300 is uneven, the auxiliary wheel can float up and down according to the unevenness of the surface to be cleaned 300 so as to always maintain contact with the surface to be cleaned 300. At the same time, the diameter of the auxiliary wheel is smaller than that of the support wheel, which can better maintain rolling on the uneven surface to be cleaned 300. At this time, in this step S101, obtaining the moving speed of the floor brush 103 by detecting the number of rotations of the auxiliary wheel by the detection unit can improve the accuracy of the obtained moving speed of the floor brush 103.

[0044] Step S102: Control the front squeegee 105 to be in a contact state or a separated state with the surface to be cleaned 300 according to the running state of the floor brush.

[0045] In the first embodiment of the present invention, controlling the front squeegee 105 to be in a contact state or a separated state with the surface to be cleaned 300 according to the running state of the floor brush may specifically include, when the running speed is less than the set speed threshold, controlling the front squeegee 105 to be in a contact state with the surface to be cleaned 300. Among them, the set speed threshold may be a preset constant speed, which may be a constant value set during the manufacturing process of the cleaning machine 100, or a constant value set by the user when using the cleaning machine 100. The set speed threshold may also be an average moving speed automatically generated by the cleaning device after learning the user's usage data.

[0046] It can be understood that the foregoing set speed threshold being a preset constant speed is only a specific illustration in the first embodiment. In some other embodiments of the present application, the set speed threshold may also be, for example, a set value calculated based on the moving speed recorded by the cleaning machine 100 during use. Specifically, for example, the average value of the moving speed of the cleaning machine 100 during a previous period of use can be calculated, and then a set multiple of the average value (such as 1 / 2, 1 / 3, 2 / 3, etc. of the average value) can be used as the set speed threshold. Due to the influence of factors such as different usage habits, different body types, different ages, different genders, etc., there are differences in the moving speeds of different people when using the cleaning machine 100. In the embodiments of the present application, calculating the set speed threshold based on the moving speed of the cleaning machine 100 during a previous period of use can make the control in this step of keeping the front squeegee 105 in a state of being in contact with or separated from the surface to be cleaned 300 more adaptable to the actual use situation of the cleaning machine 100. While improving the cleaning effect, it reduces the occurrence of the situation where the front squeegee 105 is in a state of being in contact with or separated from the surface to be cleaned 300 in an unsuitable usage state, and improves the user experience.

[0047] In the first embodiment, the control for the front squeegee 105 to be in contact with the surface to be cleaned 300 can specifically be that during the entire process where the running speed of the floor brush 103 is less than the set speed threshold, the front squeegee 105 is always kept in contact with the surface to be cleaned 300. Or in some other embodiments of the present application, the control for the front squeegee 105 to be in contact with the surface to be cleaned 300 can also be, for example, that during the entire process where the running speed of the floor brush 103 is less than the set speed threshold, the front squeegee 105 is controlled to alternately switch between being in contact with the surface to be cleaned 300 and being separated from the surface to be cleaned 300, that is, after the front squeegee 105 is in contact with the surface to be cleaned 300 for a period of time, the front squeegee 105 is controlled to be separated from the surface to be cleaned 300 for a period of time, and then the front squeegee 105 is again controlled to be in contact with the surface to be cleaned 300 for a period of time, and so on in a cycle. When the front squeegee 105 is in contact with the surface to be cleaned 300, the degree of closing of the suction cavity of the floor brush 103 is greater, and the suction force is greater. When the front squeegee 105 is separated from the surface to be cleaned 300, the degree of closing of the suction cavity of the floor brush 103 is smaller, and the suction force is smaller. Thus, when the front squeegee 105 is controlled to alternately switch between being in contact with the surface to be cleaned 300 and being separated from the surface to be cleaned 300, the suction force can be made to vary between large and small, constantly changing the suction force exerted on the dirt, which can reduce the adhesion force between the dirt and the surface to be cleaned 300 and make it easier for the dirt to separate, improving the suction cleaning effect; in addition, when the front squeegee 105 is separated from the surface to be cleaned 300, the resistance generated by the scraping member is smaller, and controlling the front squeegee 105 to alternately switch between being in contact with the surface to be cleaned 300 and being separated from the surface to be cleaned 300 can also reduce the resistance experienced by the user when using the cleaning machine 100 to a certain extent.

[0048] During the process of using the cleaning machine 100, when the running speed of the floor brush 103 is less than the preset speed threshold, it indicates that the running speed of the floor brush 103 is relatively low. The low-speed operation of the floor brush 103 usually occurs in areas where the surface to be cleaned 300 is heavily soiled. At this time, controlling the front squeegee 105 to be in contact with the surface to be cleaned 300 can, on the one hand, scrape the dirt on the surface to be cleaned 300 through the front squeegee 105, causing the dirt on the surface to be cleaned 300 to separate from the surface to be cleaned 300, and the separated dirt is easier to clean; and since the front squeegee 105 is provided on the front side of the cleaning member, when the front squeegee 105 is in contact with the surface to be cleaned 300, it can provide a certain sealing effect on the suction cavity inside the cleaning member from the front side, improving the suction ability and further enhancing the cleaning effect of the cleaning machine 100.

[0049] Further, in the first embodiment, the cleaning machine 100 further includes a water pump. During the operation of the cleaning machine 100, the water pump is used to supply water to the cleaning member. When the front squeegee 105 is in contact with the surface to be cleaned 300, the liquid supply flow rate of the water pump can be simultaneously controlled to increase. Based on the foregoing analysis, when the floor brush 103 runs at a low speed and the front squeegee 105 is in contact with the surface to be cleaned 300, this usually occurs in areas where the surface to be cleaned 300 is heavily soiled. At this time, simultaneously controlling the increase in the liquid supply flow rate of the water pump can better clean the heavily soiled areas and further improve the dirt handling ability of the cleaning system.

[0050] In the first embodiment, when the front squeegee 105 is in contact with the surface to be cleaned 300, the rotation speed of the cleaning member is also controlled to increase. Controlling the increase in the rotation speed of the cleaning member together can also better clean the heavily soiled areas and further improve the dirt handling ability of the cleaning system.

[0051] It can be understood that the foregoing control to increase the rotation speed of the cleaning member is only an example of the control process of the cleaning member in the first embodiment. In some other embodiments of the present application, it may also be that when the front squeegee 105 is in contact with the surface to be cleaned 300, the cleaning member is controlled to rotate in an alternating forward and reverse manner. The cleaning member rotating in an alternating forward and reverse manner can rub the dirt on the surface to be cleaned 300 back and forth, causing the dirt to detach from the surface to be cleaned 300, and can also improve the dirt handling ability of the cleaning system. Or in some embodiments of the present application, it may also be that both the rotation speed of the cleaning member is controlled to increase and the cleaning member is controlled to rotate in an alternating forward and reverse manner at the same time.

[0052] Further, in the first embodiment, when the running speed is greater than or equal to the preset speed threshold, the front squeegee 105 is controlled to be in a separated state from the surface to be cleaned 300. The running speed of the floor brush 103 being greater than or equal to the preset speed threshold indicates that the running speed of the floor brush 103 is relatively high. When the front squeegee 105 in contact with the ground runs at a high speed, a large resistance will be generated, affecting the user's operation of the cleaning machine 100. At this time, controlling the front squeegee 105 to be in a separated state from the surface to be cleaned 300 can avoid the resistance between the front squeegee 105 and the ground and facilitate the user's operation of the cleaning machine 100.

[0053] In the first embodiment, the control for the front squeegee 105 to be in a separated state from the surface to be cleaned 300 is that the front squeegee 105 moves upward to the highest point. Or in some other embodiments of the present application, multiple speed intervals and multiple heights of the front squeegee 105 can also be set. Each speed interval corresponds to a unique height of the front squeegee 105, and the higher the average speed of the speed interval, the higher the corresponding height of the front squeegee 105. When controlling the front squeegee 105 to be in a separated state from the surface to be cleaned 300, the corresponding height of the front squeegee 105 can be determined according to the speed interval in which the running speed of the floor brush 103 is located at this time, and the front squeegee 105 is controlled to rise to the determined height of the front squeegee 105. The higher the running speed of the floor brush 103, the greater the resistance generated when the front squeegee 105 contacts the ground. For the uneven surface to be cleaned 300, setting the higher the average speed of the speed interval and the higher the corresponding height of the front squeegee 105 can make the height of the front squeegee 105 increase as the running speed of the floor brush 103 increases. That is, as the running speed of the floor brush 103 increases, the contact probability between the floor brush 103 and the uneven surface to be cleaned 300 decreases, and the probability of generating a large resistance due to the contact between the front squeegee 105 and the surface to be cleaned 300 also decreases. Thus, on the basis of maintaining the convenience of the user operating the cleaning machine 100, when the moving speed of the floor brush 103 is lower, the rising height of the front squeegee 105 is lower, reducing the opening degree of the suction cavity of the floor brush 103 and improving the suction effect.

[0054] Compared with the related art, in the control method of the cleaning system provided in the first embodiment of the present application, the detection unit detects the floor brush running state of the floor brush 103, and controls the front squeegee 105 to be in an abutting state or a separated state with the surface to be cleaned 300 according to the floor brush running state. When the front squeegee 105 is in an abutting state with the surface to be cleaned 300, not only can the dirt and water stains on the surface to be cleaned 300 be scraped off, but also since the squeegee is arranged on the front side of the cleaning member, when the front squeegee 105 is in an abutting state with the surface to be cleaned 300, it can play a certain sealing effect on the suction cavity in the cleaning member from the front side, improving the suction capacity; when the front squeegee 105 is in a separated state from the surface to be cleaned 300, the resistance received by the user when operating the cleaning machine 100 can be reduced; since the floor brush running state detected by the detection unit in the present application includes the running speed of the floor brush 103, compared with the prior art that only controls the lifting of the squeegee according to the moving direction of the floor brush 103, controlling the front squeegee 105 to be in an abutting state or a separated state with the surface to be cleaned 300 according to the running speed of the floor brush 103 can further subdivide and specifically process more different application scenarios, making the abutting state or separated state of the front squeegee 105 with the surface to be cleaned 300 more adaptable to different application scenarios and improving the cleaning effect.

[0055] Embodiment Two

[0056] Embodiment 2 of the present application provides a control method for a cleaning system, which is substantially the same as the control method for the cleaning system provided in the foregoing Embodiment 1, and also includes steps S101 and S102 as shown in Figure 5 However, the difference is that in the foregoing Embodiment 1, the operating state of the floor brush only includes the running speed of the floor brush 103, while in Embodiment 2 of the present application, the operating state of the floor brush 103 not only includes the running speed of the floor brush 103, but also includes the running direction of the floor brush 103.

[0057] Corresponding to Embodiment 2 of the present application, in step S101, when obtaining the operating state of the floor brush detected by the detection unit, not only the running speed of the floor brush 103 detected by the detection unit is obtained, but also the running direction of the floor brush 103 detected by the detection unit is obtained. Among them, the running direction of the floor brush 103 includes forward and backward directions that are opposite to each other, corresponding to the user pushing the cleaning machine 100 forward and the user pulling the cleaning machine 100 backward respectively. When the running direction of the floor brush 103 is forward, the floor brush 103 runs in the direction ( Figure 1 、 Figure 2 in the X1 direction) in which the cleaning member faces the front squeegee 105; when the running direction of the floor brush 103 is backward, the floor brush 103 runs in the direction ( Figure 1 、 Figure 2 in the X2 direction) in which the front squeegee 105 faces the cleaning member.

[0058] Corresponding to Embodiment 2 of the present application, in step S102, controlling the front squeegee 105 to be in a contact state or a separated state with the surface to be cleaned 300 according to the operating state of the floor brush may specifically include: when the running direction is forward and decelerating, controlling the front squeegee 105 to be in a contact state with the surface to be cleaned 300.

[0059] Among them, decelerating operation means that the running speed of the floor brush 103 at the previous detection moment is greater than the running speed of the floor brush 103 at the current detection moment. It has nothing to do with the magnitude of the running speed of the floor brush 103 at a single moment, but compares the running speeds at the previous detection moment and the current detection moment to determine whether the running speed of the floor brush 103 is gradually decreasing.

[0060] Compared with the related art, in the control method for the cleaning system provided in Embodiment 2 of the present application, when the running direction is forward and the running speed is gradually decreasing, the front squeegee 105 is controlled to be in a contact state with the surface to be cleaned 300. The running direction is forward and the running speed is gradually decreasing, indicating that the forward pushing process of the user on the cleaning machine 100 is coming to an end, and the user is about to pull the cleaning machine 100 backward. At this time, controlling the front squeegee 105 to be in a contact state with the surface to be cleaned 300, during the subsequent backward pulling process of the cleaning machine 100, the front squeegee 105 in the contact state with the surface to be cleaned 300 can scrape off the water stains on the surface to be cleaned 300, reducing the water stains remaining on the surface to be cleaned 300 during the cleaning process.

[0061] Optionally, in the second embodiment, after the front squeegee 105 is controlled to be in contact with the surface to be cleaned 300, the duration of the contact between the front squeegee 105 and the surface to be cleaned 300 can be recorded. When the duration reaches a preset duration, the front squeegee 105 is controlled to switch from the contact state with the surface to be cleaned 300 to the separated state from the surface to be cleaned 300. Wherein, the start time of recording the duration is the moment when the front squeegee 105 starts to contact the surface to be cleaned 300. During the process of recording the duration, the timing is not interrupted due to changes in the running speed and running direction of the floor brush 103. Users usually operate the cleaning machine 100 to push / pull forward / backward alternately. Based on the usage habit of the cleaning machine 100, as described above, the running direction is forward and the running speed gradually decreases. After the front squeegee 105 is controlled to be in contact with the surface to be cleaned 300 when the user is about to pull the cleaning machine 100 backward, when the duration of the contact between the front squeegee 105 and the surface to be cleaned 300 reaches the preset duration, it is very likely that the user is about to push the cleaning machine 100 forward. At this time, controlling the front squeegee 105 to switch from the contact state with the surface to be cleaned 300 to the separated state from the surface to be cleaned 300 can avoid the generation of resistance between the front squeegee 105 and the ground during the forward pushing process of the cleaning machine 100, facilitating the user to operate the cleaning machine 100.

[0062] Alternatively, in the second embodiment, after the front squeegee 105 is controlled to be in contact with the surface to be cleaned 300, it can also be when the running direction is backward deceleration or the running direction is backward and the running speed is less than the set speed threshold, the front squeegee 105 is controlled to switch from the contact state with the surface to be cleaned 300 to the separated state from the surface to be cleaned 300. It can be understood that the setting method of the set speed threshold in the second embodiment is substantially the same as the setting method of the set speed threshold in the first embodiment described above. Specifically, reference can be made to the specific description in the first embodiment above. The running direction of the floor brush 103 is backward deceleration or the running direction is backward and the running speed is less than the set speed threshold, indicating that the backward pulling process of the user on the cleaning machine 100 is almost over and the user is about to push the cleaning machine 100 forward. At this time, controlling the front squeegee 105 to switch from the contact state with the surface to be cleaned 300 to the separated state from the surface to be cleaned 300 can also avoid the generation of resistance between the front squeegee 105 and the ground during the forward pushing process of the cleaning machine 100, facilitating the user to operate the cleaning machine 100.

[0063] Embodiment Three

[0064] The control method of the cleaning system provided in the third embodiment of the present application is substantially the same as the control method of the cleaning system provided in the first embodiment described above, and also includes as Figure 5Steps S101 and S102 shown above are different in that, in the first embodiment described above, the detection unit is only used to detect the operating state of the floor brush, while in the third embodiment, the detection unit is also used to detect whether there is an obstacle in front of the floor brush 103. Correspondingly, as Figure 6 shown, the control method of the cleaning system provided in the third embodiment further includes step S103: when the detection unit detects that there is an obstacle in front of the floor brush 103, control the front squeegee 105 to be in a butting state with the surface to be cleaned 300.

[0065] In the third embodiment, the detection unit can be, for example, a camera, a photoelectric detection module, etc. The detection of obstacles in front of the floor brush 103 is realized through structures such as a camera and a photoelectric detection module. Combining with the grating detection structure, electromotive force detection structure, and Hall detection structure recorded in the first embodiment above. In the third embodiment, multiple detection units can be set. Some detection units are grating detection structures, electromotive force detection structures, and Hall detection structures to realize the detection of the operating state of the floor brush, and some detection units are structures such as cameras and photoelectric detection modules to realize the detection of obstacles in front of the floor brush 103. Or in some embodiments of the present application, it can also be that the detection unit integrates a camera / photoelectric detection module and a grating detection structure / electromotive force detection structure / Hall detection structure, etc. For example, the detection unit integrates a camera and a grating detection structure at the same time, so that the detection unit can simultaneously realize the detection of obstacles in front of the floor brush 103 and the detection of the operating state of the floor brush.

[0066] Furthermore, the detection unit can also be used to measure the distance between the floor brush 103 and the obstacle, and control the running speed of the floor brush 103 according to the distance between the floor brush 103 and the obstacle. In the third embodiment, controlling the running speed of the floor brush 103 according to the distance between the floor brush 103 and the obstacle specifically means that when the distance between the floor brush 103 and the obstacle is less than the set distance threshold, control the speed of the floor brush 103 to be not greater than the collision speed. Among them, the set distance threshold and the collision speed are preset constant distance and constant speed. The cleaning system actively controls the speed of the floor brush 103 to be not greater than the collision speed, which can not only avoid violent collisions between the floor brush 103 and the obstacle, but also when cleaning positions such as corners, there is no need for the user to control the running speed of the cleaning machine 100, reducing the force on the user's hand and improving the user experience.

[0067] Among them, controlling the speed of the floor brush 103 to be not greater than the collision speed can specifically mean controlling the floor brush 103 to decelerate to not greater than the collision speed when the running speed of the floor brush 103 is greater than the collision speed.

[0068] It can be understood that when the distance between the aforementioned floor brush 103 and the obstacle is less than the set distance threshold, controlling the speed of the floor brush 103 to be no greater than the collision speed is only a specific description in the third embodiment. In some other embodiments of the present application, controlling the running speed of the floor brush 103 according to the distance between the floor brush 103 and the obstacle can also be, for example, setting multiple preset distances and multiple preset speeds, with each preset distance corresponding to a unique preset speed, and the greater the preset distance, the greater the corresponding preset speed. Each time the distance between the floor brush 103 and the obstacle is less than any of the preset distances, the speed of the floor brush 103 is controlled to be no greater than the preset speed corresponding to the preset distance, so as to achieve multi-stage gradual deceleration, avoid a sudden decrease in the moving speed of the floor brush 103, and further improve the user experience.

[0069] In the embodiments of the present application, the active control of the running speed of the floor brush 103 can be specifically achieved by the assist unit support wheel provided on the floor brush 103. That is, in the embodiments of the present application, the floor brush 103 further includes an assist unit support wheel. When the floor brush 103 needs to decelerate, the assist unit support wheel is controlled to rotate in the direction opposite to the running direction of the floor brush 103. At this time, the rotation direction of the assist unit support wheel is opposite to the rotation direction of the cleaning member to reduce the running speed of the floor brush 103; when the floor brush 103 needs to accelerate, the assist unit support wheel is controlled to rotate in the same direction as the running direction of the floor brush 103. At this time, the rotation direction of the assist unit support wheel is the same as the rotation direction of the cleaning member to increase the running speed of the floor brush 103. Among them, the rotation speed of the assist unit support wheel is less than the rotation speed of the cleaning member.

[0070] Furthermore, in some embodiments of the present application, the handle 101 may further include a pressure sensor. The pressure sensor is used to measure the force applied by the user to the handle, and based on the magnitude of the force sensed by the pressure sensor and combined with the running direction of the floor brush detected by the detection unit, it controls the assist unit support wheel to provide assistance to reduce the force exerted by the user when pushing / pulling the cleaning machine.

[0071] Compared with the related art, in the control method of the cleaning system provided in the third embodiment, when the detection unit detects an obstacle in front of the floor brush 103, it indicates that the distance between the floor brush 103 and the obstacle is relatively close. Since the front squeegee 105 is arranged in front of the floor brush 103, at this time, the front squeegee 105 is controlled to be in a state of abutting against the surface to be cleaned 300. The front squeegee 105 that has descended to the state of abutting against the surface to be cleaned 300 can also abut against the obstacle. When the cleaning machine 100 is pulled backward, the front squeegee 105 that abuts against the obstacle can drive the dirt near the obstacle that is difficult to be sucked away to retreat, facilitating the subsequent suction of this dirt; in addition, when the floor brush 103 approaches the obstacle, the front squeegee 105 is controlled to be in a state of abutting against the surface to be cleaned 300. When the floor brush 103 collides with the obstacle, the front squeegee 105 first collides with the obstacle to absorb energy, reducing the damage caused to the floor brush 103 by the collision between the floor brush 103 and the obstacle.

[0072] Embodiment Four

[0073] The fourth embodiment of the present application provides a control method for a cleaning system. As Figure 1 , Figure 3 shown, the cleaning system to which the control method of the cleaning system provided in the fourth embodiment is applied further includes a sewage suction system, and the sewage suction system includes a sewage suction motor, a sewage suction pipe 201, and a sewage bucket 202. In the control method of the cleaning system provided in the fourth embodiment, the step S101 and step S102 as Figure 5 shown are also included. The difference is that, as Figure 7 shown, in the fourth embodiment, it further includes step S104: controlling the power of the sewage suction motor to increase / decrease according to the running state of the floor brush.

[0074] Specifically, in the fourth embodiment, controlling the power of the sewage suction motor to increase / decrease according to the running state of the floor brush in step S104 may specifically include: when the running direction is forward and the running speed is less than the set speed threshold, controlling the power of the sewage suction motor to decrease.

[0075] In this embodiment, after controlling the power of the sewage suction motor to decrease, timing can also be started. After the power of the sewage suction motor has decreased for the set duration, controlling the power of the sewage suction motor to increase; or when the running state of the floor brush changes to the running direction being backward / the running speed being greater than or equal to the set speed threshold, controlling the power of the sewage suction motor to increase.

[0076] Compared with the related art, in the control method of the cleaning system provided in the fourth embodiment, when the running direction is forward and the running speed is less than the set speed threshold, the power of the sewage suction motor is controlled to decrease. The running direction of the floor brush 103 is forward and the running speed is less than the set speed threshold, indicating that the user intentionally controls the floor brush 103 to move forward at a low speed. At this time, the probability of items such as electrical wires and food pits that are not suitable for being sucked into the sewage suction pipeline appearing near the cleaning machine 100 is relatively high. Controlling the power of the sewage suction motor to decrease can reduce the possibility of items that are not suitable for being sucked into the sewage suction pipeline being sucked into the sewage suction pipeline, and improve the running safety of the cleaning machine 100.

[0077] Further, in some embodiments of the present application, the sewage suction system may further include a foreign object detection device. The foreign object detection device can detect various objects in the sewage suction pipeline and determine whether there are foreign objects in the sewage suction pipeline that are not suitable or cannot be sucked into the sewage bucket. Among them, the foreign object detection device can be arranged inside the sewage suction pipeline, for example. On this basis, the control method of the cleaning system further includes: when the foreign object detection device detects that there is a foreign object in the sewage suction pipeline, controlling the cleaning member to switch the rotation direction. Specifically, the foreign object detection device can be a pressure detection device, a current detection device, a voltage detection device, etc.

[0078] When the foreign object detection device detects that there is a foreign object in the sewage suction pipeline that is not suitable or cannot be sucked into the sewage bucket, controlling the cleaning member to switch the rotation direction can promptly eject the foreign object in the sewage suction pipeline, reduce the possibility of the foreign object blocking the sewage suction pipeline or damaging the sewage suction pipeline, and improve the use experience and running safety of the cleaning machine 100.

[0079] Embodiment Five

[0080] The fifth embodiment of the present application provides a control method for a cleaning system. As Figure 8 shown, the cleaning system to which the control method of the cleaning system provided in the fifth embodiment is applied further includes a base 400 for placing the cleaning machine 100. In the fifth embodiment, the cleaning system also has a self-cleaning function, that is, when the cleaning machine 100 is placed on the base 400, the cleaning machine 100 is automatically cleaned. Based on this, the control method of the cleaning system provided in the fifth embodiment further includes, during the self-cleaning process of the cleaning machine 100, controlling the front squeegee 105 to abut against the base at least once.

[0081] Specifically, in the fifth embodiment, controlling the front squeegee 105 to abut against the base at least once specifically means controlling the front squeegee 105 to always maintain an abutting state with the base. Or in some other embodiments of the present application, controlling the front squeegee 105 to abut against the base at least once can also mean controlling the front squeegee 105 to separate from the base after abutting against the base for a period of time, or controlling the front squeegee 105 to repeatedly abut against and separate from the base several times and other implementation methods.

[0082] Further, as Figure 8 shown, the base 400 includes a receiving groove 401 for placing the cleaning machine 100. The receiving groove 401 includes a bottom wall 402 and a side wall 403, and an air outlet 404 is provided on the side wall 403. In the fifth embodiment, controlling the front squeegee 105 to abut against the base specifically means controlling the front squeegee 105 to abut against the bottom wall. When the front squeegee 105 abuts against the bottom wall, it can block the liquid in the receiving groove, reducing the possibility of the liquid in the receiving groove entering the air outlet.

[0083] Compared with the related art, in the control method of the cleaning system provided in the fifth embodiment, during the self-cleaning process, the front squeegee 105 is controlled to abut against the base at least once. This can not only effectively clean the front squeegee 105, but also the front squeegee 105 can block the cleaning liquid splashing forward during the self-cleaning process, reducing the liquid splash during the cleaning process.

[0084] Embodiment Six

[0085] The sixth embodiment of the present application provides a control method for a cleaning system. As Figure 9 shown, the cleaning system to which the control method of the cleaning system provided in the sixth embodiment is applied further includes a base 400 for placing the cleaning machine 100. In the sixth embodiment, the cleaning system further has a drying function, that is, when the cleaning machine 100 is placed on the base 400, the cleaning machine 100 is automatically dried. Based on this, in the control method of the cleaning system provided in the sixth embodiment, it further includes controlling the front squeegee 105 to abut against the base during the drying process of the cleaning machine 100.

[0086] Specifically, in the sixth embodiment, controlling the front squeegee 105 to abut against the base specifically means controlling the front squeegee 105 to always maintain an abutting state with the base. Or in some other embodiments of the present application, controlling the front squeegee 105 to abut against the base can also mean controlling the front squeegee 105 to separate from the base after abutting against the base for a period of time, or controlling the front squeegee 105 to repeatedly abut against and separate from the base several times and other implementation methods.

[0087] Further, as Figure 9 shown, the base 400 includes a receiving groove 401 for placing the cleaning machine 100. The receiving groove 401 includes a bottom wall 402, a side wall 403 and a top wall 405, and an air outlet 404 is provided on the side wall 403. In the sixth embodiment, controlling the front squeegee 105 to abut against the base specifically means controlling the front squeegee 105 to abut against the top wall. When the front squeegee 105 abuts against the top wall, it can seal the receiving groove, enabling the air flow blown out from the air outlet to flow in the space formed by the cleaning machine 100 and the receiving groove, reducing heat dissipation and improving the drying efficiency of the cleaning machine 100.

[0088] Compared with the related art, in the control method of the cleaning system provided in the sixth embodiment, after the front squeegee 105 is controlled to abut against the base during the drying process, the front squeegee 105 can provide a certain sealing effect on the dirt suction cavity in the cleaning member from the front side, so that the drying air flow can flow in the space formed by the cleaning machine 100 and the receiving groove during the drying process, improving the drying effect.

[0089] The above is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed in the present application should be covered by the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
