Description

Technical Field

[0001] The present application relates to the technical field of cleaning equipment, and in particular to a cleaning system control method and a water storage barrel closing method. Background Art

[0002] With the development of science and technology and the improvement of people's living standards, shopping malls, stations, hotels and other commercial areas as well as more and more families have begun to use various cleaning equipment to reduce labor intensity and improve labor efficiency. Among them, floor scrubbers integrate washing, mopping, suction and other functions in one, and can complete deep cleaning of the target site by hand-held push and pull, which is widely welcomed by users.

[0003] The floor scrubber is usually equipped with a base station, which can realize automatic cleaning of the floor scrubber. When the sewage bucket of the floor scrubber needs to be cleaned, the base station can first open the sewage outlet cover of the sewage bucket to discharge the sewage, and then use the flushing device set on the base station to flush the inner wall of the sewage bucket, and close the sewage bucket after the flushing operation is completed.

[0004] However, the existing base station usually extends the flushing device into the sewage bucket through the sewage outlet for flushing. If the flushing device does not exit the sewage bucket when the sewage outlet cover is closed, the sewage outlet cover will be severely collided and squeezed with the flushing device and damaged, resulting in the entire floor scrubber being unable to be used normally. Summary of the invention

[0005] The embodiment of the present application provides a base station, a cleaning system and a control method thereof, which can solve the problem that the opening cover of the water storage bucket is damaged due to severe collision and extrusion with the flushing device. To achieve the above purpose, the technical solution provided by the embodiment of the present application is as follows:

[0006] In a first aspect, the present application provides a control method for a cleaning system, the cleaning system comprising a cleaning device and a base station; the cleaning device is provided with a water storage bucket, an opening cover is provided on the opening of the water storage bucket, and the base station is provided with a first closing device and a second closing device; the control method comprises:

[0007] Controlling the first closing device to move toward the opening of the water storage barrel until the first closing device abuts against the opening cover plate and pushes the opening cover plate to a first closing position;

[0008] The second closing device is controlled to move toward the opening of the water storage barrel until the second closing device abuts against the opening cover plate, and the opening cover plate is pushed to a second closing position to close the water storage barrel.

[0009] In a second aspect, the present application provides a method for closing a water storage barrel, which is applied to a base station, wherein the base station includes a first closing device and a second closing device; the method for closing the barrel includes:

[0010] Controlling the first closing device to move toward the opening of the water storage barrel until the first closing device abuts against the opening cover of the water storage barrel and pushes the opening cover to a first closing position;

[0011] The second closing device is controlled to move toward the opening of the water storage barrel until the second closing device abuts against the opening cover plate, and the opening cover plate is pushed to a second closing position to close the water storage barrel.

[0012] In a third aspect, the present application provides a cleaning system, which includes a cleaning device and a base station; the cleaning device is provided with a water storage bucket, and the base station is provided with a switch auxiliary device, a flushing device, a controller and a memory; the memory is used to store a computer program, and the controller is coupled to the memory for executing the computer program to implement the method described in the first aspect.

[0013] In a fourth aspect, the present application provides a base station for a cleaning device, wherein the cleaning device is provided with a water storage bucket; the base station comprises: a switch auxiliary device, a flushing device, a controller and a memory, wherein the memory is used to store a computer program, and the controller is coupled to the memory for executing the computer program to implement the method described in the first aspect or the second aspect.

[0014] In a fifth aspect, the present application provides a computer-readable storage medium, wherein the computer storage medium stores a plurality of instructions, wherein the instructions are suitable for being loaded by a processor and executing the method described in the first aspect or the second aspect.

[0015] As can be seen from the above, the technical solution provided by the present application can decompose the operation of closing the water storage barrel into two parts, the first half of which is performed by the first closing device, and the second half of which is performed by the second closing device. Compared with the technical solution of using the first closing device to directly completely close the opening cover of the water storage barrel opening, the stroke of the first closing device when closing the water storage barrel is shortened. Specifically, the first closing device is first used to push the opening cover to the first closing position, so that the opening cover is in a semi-closed state; and then the second closing device is used to push the opening cover to the second closing position, so that the opening cover reaches a fully closed state. In this way, before the second closing device pushes the opening cover, the opening cover will always be in a semi-closed state due to the support of the first closing device. If the second closing device set on the base station fails to withdraw from the water storage barrel in time for some reason, the opening cover in a semi-closed state will not clamp the second closing device, thereby avoiding damage to the components at the opening of the water storage barrel, ensuring that the cleaning equipment (for example, a handheld floor scrubber) will not be damaged or affected by abnormal operation of the base station.

[0027] Terms used in this application to indicate spatial relative positions, such as "upper", "above", "lower", "below", "first end", "second end", "one end", "the other end", etc., are for the purpose of convenience of explanation to describe the relationship of one unit or feature relative to another unit or feature as shown in the accompanying drawings. Terms of spatial relative position may be intended to include different orientations of the device in use or operation other than the orientation shown in the figure. For example, if the device in the figure is turned over, the unit described as being "below" or "beneath" other units or features will be located "above" the other units or features. Therefore, the exemplary term "below" can encompass both the above and below orientations. The device may be oriented in other ways (rotated 90 degrees or in other orientations), and the spatially related descriptors used herein interpreted accordingly.

[0028] In addition, the terms "installed", "set", "provided with", "connected", "slidingly connected", "fixed", and "sleeved" should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be an internal connection between two devices, elements, or components. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0029] With the development of science and technology and the improvement of people's living standards, shopping malls, stations, hotels and other commercial areas, as well as more and more families, have begun to use various cleaning equipment to reduce labor intensity and improve labor efficiency. Among them, floor scrubbers integrate the functions of washing, mopping, and suction. They can complete the deep cleaning of the target site by hand-held push and pull, and are widely welcomed by users. Floor scrubbers are generally equipped with base stations, which realize automatic cleaning of floor scrubbers. When it is necessary to clean the sewage bucket of the floor scrubber, the base station can first open the sewage outlet cover of the sewage bucket to discharge the sewage, and then use the flushing device set on the base station to flush the inner wall of the sewage bucket, and close the sewage bucket after the flushing operation is completed.

[0030] However, in order to deeply clean the sewage bucket, the existing base station usually needs to extend the flushing device into the sewage bucket through the sewage outlet of the sewage bucket to perform flushing operations. The flushing operation may include: controlling the flushing device to move toward the sewage outlet until the flushing device reaches a preset flushing position in the sewage bucket; controlling the flushing device to spray liquid to flush the inner wall of the sewage bucket and discharge the liquid from the sewage outlet at the bottom of the sewage bucket; and controlling the flushing device to reciprocate in the sewage bucket to flush the inner wall of the sewage bucket to a deeper degree; finally, controlling the flushing device to move away from the sewage outlet until it exits the sewage bucket.

[0031] If the flushing device fails to exit the sewage bucket for various reasons when the drain outlet cover is closed, the drain outlet cover will be damaged due to severe collision and extrusion with the flushing device, resulting in the entire floor scrubber being unable to be used normally.

[0032] For example, user Xiao Ming used a floor scrubber to clean the entire room. When the floor scrubber was put back into the base station for automatic cleaning, due to improper operation and excessive force, the floor scrubber and the base station were not docked accurately and collided. This caused some components in the base station to malfunction and fail. When the base station starts working, it controls the flushing device to extend into the sewage bucket and spray liquid to flush and clean the sewage bucket. Under normal circumstances, after flushing the sewage bucket, the base station can control the flushing device to exit the sewage bucket, and then control the switch auxiliary device to close the sewage outlet cover. However, since some components related to the flushing operation and / or the barrel closing operation in the base station have failed, the flushing device cannot be exited normally, and the base station will continue to close the sewage outlet cover according to the preset program. After a while, the sewage outlet cover was damaged due to severe collision and extrusion with the flushing device. Immediately afterwards, the sewage outlet cover was subjected to excessive force and pressed the flushing device, which stuck the flushing device between the sewage outlet and the cover, causing the sewage outlet to be squeezed and deformed.

[0033] Based on this, the present application changes the way the base station closes the sewage bucket of the cleaning equipment. The operation of closing the sewage bucket is divided into two parts. The first half uses a switch auxiliary device to assist the bucket closing operation, and the second half uses a flushing device to lead the bucket closing operation. In this way, even if the flushing device does not exit the sewage bucket in time, the sewage outlet cover in a semi-closed state will not clamp the flushing device, thereby avoiding damage to the bottom components of the sewage bucket.

[0034] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the embodiments described in this application are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of this application.

[0035] See also Figure 1 One embodiment of the present application provides a cleaning system including a cleaning device 1 (such as a floor scrubber) and a base station 2; the cleaning device 1 is provided with a water storage bucket 11, and the base station 2 is provided with a first closing device 21 and a second closing device 22. The control method of the cleaning system includes the following steps:

[0036] S102, controlling the first closing device to move toward the opening of the water storage barrel until the first closing device abuts against the opening cover of the water storage barrel and pushes the opening cover to a first closing position.

[0037] The water storage bucket may be a container that can hold liquids, such as a clean water bucket, a sewage bucket, or a detergent bucket. The water storage bucket may be provided with an opening, and an opening cover may be provided on the opening of the water storage bucket. The following will take the water storage bucket as an example of a sewage bucket. When the water storage bucket is a sewage bucket, the opening of the water storage bucket may be a sewage outlet of the sewage bucket, and the sewage outlet may be provided on the bottom surface of the sewage bucket, so as to facilitate the complete emptying of the sewage in the bucket.

[0038] In one embodiment, the first closing device may be a switch auxiliary device for opening and closing the opening cover of the water storage barrel, such as an existing cover opening and closing device, and the second closing device may be a flushing device for flushing the water storage barrel. Figure 2-3 The floor scrubber 1 may include a sewage bucket 11. Usually, the user can hold the floor scrubber to clean the target area, and when the cleaning is completed, the floor scrubber can be placed on the base station for storage, water addition, sewage discharge, automatic cleaning, drying, charging and other maintenance. The base station 2 used in conjunction with the floor scrubber 1 may be provided with a switch auxiliary device 21 for opening and closing the sewage bucket of the floor scrubber and a flushing device 22 for flushing the dirt on the inner wall of the sewage bucket.

[0039] In actual application, when the user holds the floor scrubber to clean the target area, the floor scrubber can attract dirt into the sewage bucket, and the sewage bucket's sewage outlet cover is in a completely closed state. When the sewage bucket needs to be drained or flushed, the floor scrubber can be docked with the base station. Then, the switch auxiliary device 21 can move toward the sewage outlet of the sewage bucket 11. When the switch auxiliary device 21 moves a certain distance from the initial position, it can abut against the sewage outlet cover of the sewage bucket 11, and then continue to move toward the sewage outlet, and the sewage outlet cover can be pushed to the first closed position, so that the sewage outlet cover is in a semi-closed state.

[0040] S104, controlling the second closing device to move toward the opening of the water storage barrel until the second closing device abuts against the opening cover of the water storage barrel, and pushing the opening cover to a second closing position to close the water storage barrel.

[0041] In actual application, the base station can control the switch auxiliary device 21 to push the sewage outlet cover to the first closed position. After that, the flushing device 22 can also be controlled to move toward the sewage outlet. When the flushing device moves a certain distance from the initial position, it will abut against the sewage outlet cover, and then continue to move toward the sewage outlet, and then the sewage outlet cover can be pushed to the second closed position, thereby closing the sewage bucket.

[0042] Based on this embodiment, the present application decomposes the operation of closing the sewage bucket into two parts, the first half is performed by the switch auxiliary device, and the second half is performed by the flushing device. Compared with the technical solution of using the switch auxiliary device to directly completely close the sewage outlet cover, the travel of the switch auxiliary device when closing the sewage bucket is shortened. Specifically, the switch auxiliary device is first used to push the sewage outlet cover to the first closed position, so that the sewage outlet cover is in a semi-closed state; and then the flushing device is used to push the sewage outlet cover to the second closed position, so that the sewage outlet cover reaches a fully closed state. In this way, before the flushing device pushes the sewage outlet cover, the sewage outlet cover will be in a semi-closed state due to the action of the switch auxiliary device. If the flushing device set on the base station does not withdraw from the sewage bucket in time for some reason, the cover in the semi-closed state will not clamp the flushing device, thereby avoiding damage to the bottom component of the sewage bucket, ensuring that the cleaning equipment (for example, a handheld floor scrubber) will not be damaged and affected by abnormal operation of the base station.

[0043] In one embodiment, the first closing device can move along a first direction to push the opening cover of the water storage barrel to a first closed position; the second closing device can move along a second direction to push the opening cover of the water storage barrel to a second closed position; wherein the first direction is different from the second direction.

[0044] In implementation, the first closing device and the second closing device can be set at different positions on the base station. Accordingly, the first closing device and the second closing device can move in different directions, and by cooperating with each other, the opening cover of the water bucket is pushed to a specified position to complete the bucket closing operation. In this way, the second closing device must be located outside the opening of the water bucket to successfully close the water bucket. Compared with using a single first closing device to perform the operation of closing the water bucket, this embodiment can prevent the second closing device from being stuck at the opening of the water bucket when closing the bucket. Similarly, it can also prevent various foreign objects including parts of the cleaning equipment itself from being stuck at the opening of the water bucket when closing the bucket, causing damage to the equipment.

[0045] In one embodiment, the switch auxiliary device can be arranged on the side of the sewage bucket to move laterally toward the sewage outlet; the flushing device is arranged under the sewage bucket to move longitudinally toward the sewage outlet.

[0046] In implementation, the switch auxiliary device can move laterally toward the sewage outlet, so that when the switch auxiliary device is used to close the barrel, a lateral thrust can be generated on the sewage outlet cover. During the process of the switch auxiliary device moving laterally toward the sewage barrel, its movement trajectory can intersect with the sewage outlet cover located at the first closed position. In this way, it is ensured that the switch auxiliary device can continuously contact the sewage outlet cover and push the sewage outlet cover laterally when performing the barrel closing operation.

[0047] It is worth mentioning that when the sewage outlet cover moves to the first closed position, the switch auxiliary device no longer needs to move toward the sewage outlet. At this time, the switch auxiliary device can be connected to the sewage outlet cover and can support the sewage outlet cover.

[0048] In one embodiment, the first closed position can be determined according to the travel of the switch auxiliary device. For example, the switch auxiliary device can move laterally toward the sewage outlet (moving to the left in the embodiment shown in the drawings) by about 23 cm, so that the sewage outlet cover moves to the first closed position.

[0049] Furthermore, after the drain outlet cover plate moves to the first closed position, the flushing device can move longitudinally toward the drain outlet (upward in the embodiment shown in the attached figure). In this way, when the flushing device is used to close the barrel, a longitudinal thrust can be generated on the drain outlet cover plate. After the flushing device moves about 6 cm, the drain outlet cover plate is pushed to the second closed position. In the process of the flushing device moving longitudinally toward the sewage barrel, its movement trajectory can intersect with the drain outlet cover plate located in the first closed position. In this way, it is ensured that the flushing device can continuously contact and longitudinally push the drain outlet cover plate when performing the barrel closing operation.

[0050] It can be understood that the dimensions of the floor scrubber, base station, and its various components can be configured according to actual needs, so the distance range within which the switch auxiliary device and the flushing device can move toward the sewage outlet can also be set according to actual needs, and this application does not impose any restrictions on this.

[0051] In one embodiment, the first closed position can also be determined based on the positional relationship with any component. For example, the angle between the first closed position and the plane of the sewage bucket drain outlet can be about 90°. Of course, the dimensions, assembly positions and relationships of the floor scrubber, base station, and their components can be configured according to actual needs, so the angle between the first closed position and the plane of the sewage bucket drain outlet can also be determined according to actual conditions, and this application does not impose any restrictions on this. It is worth mentioning that the straight line where the flushing device is located can intersect with the plane where the drain outlet cover plate is located in the first closed position. In this way, it can be ensured that the flushing device can abut against the drain outlet cover plate during the longitudinal movement toward the drain outlet, and push the drain outlet cover plate to be completely closed.

[0052] In one embodiment, see Figure 4 The switch auxiliary device 21 may include an upper push rod 211 and a lower push rod 212, wherein the upper push rod 211 may be used to open the sewage outlet cover plate 112 of the sewage bucket, and the lower push rod 212 may be used to close the sewage outlet cover plate 112 of the sewage bucket. Based on this structure, step S102 may specifically include: controlling the lower push rod to move toward the sewage outlet until the lower push rod abuts against the sewage outlet cover plate, and pushing the sewage outlet cover plate to the first closed position.

[0053] In implementation, the switch auxiliary device may further include a gear 213 disposed between the upper push rod 211 and the lower push rod 212. The gear 213 may mesh with the rows of teeth disposed on the upper push rod 211 and the lower push rod 212. When the base station of the floor scrubber drives the gear 213 to rotate via the built-in motor, the upper push rod 211 and the lower push rod 212 move in the opposite direction. Based on this structure, in the barrel closing operation, the movement of the switch auxiliary device toward the sewage outlet can be understood as: the lower push rod 212 moves toward the sewage outlet 111. In the barrel opening operation, the movement of the switch auxiliary device toward the sewage outlet can be understood as: the upper push rod 211 moves toward the sewage outlet 111.

[0054] Based on this embodiment, the upper push rod and the lower push rod can be driven by one gear, and there is no need to set up two driving mechanisms to drive the upper push rod and the lower push rod respectively. It can be seen that the switch auxiliary device provided by this application has a simple structure and saves hardware costs.

[0055] In another embodiment, the switch auxiliary device may be a steering gear. Accordingly, step S102 may specifically include: controlling the steering wheel of the steering gear to rotate toward the sewage outlet until the steering wheel abuts against the sewage outlet cover plate, and pushing the sewage outlet cover plate to the first closed position.

[0056] See also Figure 8 The steering gear 21 may generally include a steering plate 212-1 and a rotating shaft 213-1. It is understood that the steering plate 212-1 may be used to abut against the drain outlet cover plate 112 to push the drain outlet cover plate 112. When the steering gear 21 is controlled to close the sewage bucket 11, that is, when the drain outlet cover plate 112 of the sewage bucket 11 is closed, the steering plate 212-1 may be driven to rotate toward the drain outlet 111 of the sewage bucket (clockwise rotation is shown in the figure) by controlling the rotating shaft 213-1 of the steering gear until the steering plate 212-1 abuts against the drain outlet cover plate 112 and pushes the drain outlet cover plate 112 to the first closed position.

[0057] Afterwards, see Fig. 9 The flushing rod 221 of the flushing device 22 can be driven by the stepper motor to move toward the sewage outlet 111 until the flushing rod 221 abuts against the sewage outlet cover 112 and pushes the sewage outlet cover 112 to the second closing position to close the sewage bucket 11.

[0058] In one embodiment, in order to reduce the complexity of the structure and simplify the method of opening and closing the sewage bucket, it can be considered that both the bucket opening operation and the bucket closing operation are performed by a single steering wheel of the steering gear. Figure 5-7 The lock assembly provided on the sewage outlet 111 of the sewage bucket shown in the figure can be a female buckle of a spring-pressed switch, and the protrusion provided on the sewage outlet cover 112 can be a male buckle of a spring-pressed switch. In this way, the sewage outlet cover can be opened by pressing once and locked by pressing again.

[0059] Based on this structure, when the closed sewage outlet cover plate 112 needs to be opened, the steering gear can be controlled to drive the steering plate to move toward the sewage outlet of the sewage bucket and abut against the sewage outlet cover plate 112. Fig.10 , the locked male buckle and female buckle (not shown in the figure) can be pushed open by being pressed, at this time, the steering gear can be controlled to reverse to reset, and then the sewage outlet cover plate 112 is opened. When the opened sewage outlet cover plate 112 needs to be closed, the steering gear can be controlled to drive the steering wheel to move toward the sewage outlet and push the sewage outlet cover plate 112 to the first closed position, and then the flushing rod 221 of the flushing device 22 is controlled to push the sewage outlet cover plate 112 to the second closed position, at this time, the separated male buckle and female buckle can be pressed to be locked.

[0060] It is worth mentioning that in order to ensure the sealing of the sewage outlet of the sewage bucket, a sealing gasket can be provided on the sewage outlet or the sewage outlet cover, so that the sewage outlet cover can be in close contact with the sewage outlet when closed to prevent dirt from leaking. Furthermore, in order to provide a pressing space for the spring press switch, the sealing gasket can be selected from an elastic material that can be squeezed and deformed, such as rubber.

[0061] Based on this embodiment, the servo can save space and has a simple structure compared to the laterally extending double-rod structure. In addition, a single servo can perform the barrel opening operation and the auxiliary barrel closing operation, which can reduce the complexity of the barrel opening and closing operation.

[0062] It is worth mentioning that when the lock assembly adopts a spring-pressed switch, the flushing device can also press the closed drain outlet cover plate upward to open it. However, the sewage bucket of the floor scrubber usually needs to open the drain outlet cover plate for sewage discharge and / or flushing operation only when it is filled with dirt. When there is a lot of dirt in the sewage bucket, due to the effect of gravity, the dirt in the sewage bucket will exert a large pressure on the drain outlet cover plate at the bottom of the sewage bucket. At this time, it is necessary to apply a large thrust to the drain outlet cover plate to open the spring press switch. It can be seen that if the flushing device is used to open the drain outlet cover plate, the power requirements of the flushing device are high. If the flushing device is not powered enough, it may cause the drain outlet cover plate to be unable to be opened, or cause the drain outlet cover plate to be suddenly slapped downward by the pressure of the dirt, thereby causing damage. Therefore, in a preferred embodiment, a lateral thrust can be applied to the drain outlet cover plate to open the drain outlet cover plate, or a servo with suitable power can be used to press and open the drain outlet cover plate at the bottom of the sewage bucket. The model and specification of the servo can be selected according to needs, and this application does not limit this.

[0063] In one embodiment, to ensure that the first closing device and the second closing device do not collide, when the opening cover of the water storage barrel is in the first closing position, the movement paths of the first closing device and the second closing device are separated.

[0064] In practice, when the first closing device pushes the opening cover of the water storage barrel to the first closing position, the second closing device can start to perform the second half of the barrel closing operation. If the first closing device is located on the movement path of the second closing device at this time, the second closing device will collide with the first closing device when moving toward the opening of the water storage barrel, thereby causing damage to the first closing device and other parts. However, this embodiment can control the movement distance of the first closing device, so that when the opening cover of the water storage barrel is pushed to the first closing position, the position of the first closing device does not exceed the movement path of the second closing device, thereby avoiding the second closing device from colliding with the first closing device during the movement.

[0065] In one embodiment, see again Figure 4 The flushing device 22 may include a flushing rod 221 and a stepper motor 222. Based on this structure, step S104 may specifically include: driving the stepper motor 222 to drive the flushing rod 221 to move toward the sewage outlet 111 until the flushing rod 221 abuts against the sewage outlet cover plate 112, and pushing the sewage outlet cover plate 112 to the second closing position to close the sewage bucket 11.

[0066] In practice, before flushing the sewage bucket, the closed sewage bucket needs to be opened. Accordingly, the control method of the cleaning system may further include a bucket opening step, specifically including: before flushing the sewage bucket, controlling the upper push rod to move toward the sewage outlet until the upper push rod abuts against the sewage outlet cover plate to push the sewage outlet cover plate open.

[0067] In one embodiment, a sewage outlet cover is rotatably fixed on one side of the sewage outlet of the sewage bucket, and a locking assembly is correspondingly arranged on the other side of the sewage outlet of the sewage bucket. Accordingly, step S104 may specifically include: pushing the sewage outlet cover to the second closed position so that the locking assembly locks the sewage outlet cover.

[0068] See also Figure 5-7 The sewage outlet 111 of the sewage bucket 11 may also be provided with a lock 1111 and a release link 1112, and the sewage outlet cover 112 has a protrusion 1121 (can be called a male buckle) for the lock 1111 (can be called a female buckle) to buckle. The release link 1112 extends from the position of the lock 1111 to the side of the sewage outlet 111 adjacent to the upper push rod 211.

[0069] See also Figure 5When the sewage outlet cover 112 is in the closed state, the upper push rod 211 can move laterally to abut against the release link 1112 provided on the sewage outlet 111. When the upper push rod 211 abuts against the action area of ​​the release link 1112, the release link 1112 can be moved (moving to the left in the embodiment shown in the attached figure). In this way, the release link 1112 will further push the lock buckle 1111 to move, so that the lock buckle 1111 and the protrusion 1121 are no longer buckled, and then the lock buckle 1111 is disengaged from the sewage outlet cover 112, and the sewage outlet cover 112 of the sewage bucket is opened. The schematic diagram of the sewage outlet cover 112 in the open state can be seen in Figure 6 .

[0070] Based on this embodiment, the drain outlet cover can be locked by the lock assembly, so that the sewage bucket of the floor scrubber can be kept in a closed state, and after the drain outlet cover is locked, the sewage bucket can be opened simply by pushing the release connecting rod. In other words, the cleaning system and control method provided by this application can ensure that the bucket is closed safely and reliably, and opened conveniently and quickly.

[0071] It is worth mentioning that the upper push rod 211 can move laterally away from the sewage outlet after the sewage outlet cover is opened, and the movement distance is at least enough for the upper push rod 211 to no longer abut against the release link 1112. Accordingly, the release link 1112 can move to the right under the action of the spring, thereby resetting the lock buckle 1111.

[0072] In one embodiment, to ensure that the drain outlet cover plate can move under the thrust of the opening and closing auxiliary device or the flushing device, one end of the drain outlet cover plate can be rotatably fixed to the drain outlet. In this way, the drain outlet cover plate can be rotatably opened or closed when the drain outlet cover plate is subjected to the thrust of the opening and closing auxiliary device or the flushing device.

[0073] In practice, one side of the drain outlet cover plate 112 can be rotatably connected to one side of the drain outlet through a C-shaped stopper. Of course, the drain outlet cover plate 112 and the drain outlet 111 can also be hinged, or other movable connection methods can be used, which is not limited in this application.

[0074] In one embodiment, after the floor scrubber performs certain cleaning tasks, it is not necessary to flush the sewage bucket, and only the sewage discharge operation is performed to discharge the dirt in the sewage bucket. Accordingly, after opening the sewage outlet cover of the sewage bucket and emptying the dirt in the bucket, the switch auxiliary device can be controlled to push the sewage outlet cover to the first closed position, and the flushing device can be controlled to push the sewage outlet cover located in the first closed position to the second closed position to close the sewage outlet cover of the sewage bucket. The schematic diagram of the sewage outlet cover 112 located in the first closed position (i.e., in a semi-closed state) can be seen in FIG. Figure 7 .

[0075] Based on the same technical concept, the embodiment of the present application also provides a new method for closing a sewage bucket, which can be applied to a base station matched with a cleaning device. The base station may include a switch auxiliary device and a flushing device; the method for closing the bucket may include:

[0076] After the dirt in the sewage bucket is emptied, the switch auxiliary device is controlled to move toward the sewage outlet of the sewage bucket until the switch auxiliary device abuts against the sewage outlet cover of the sewage bucket, and the sewage outlet cover is pushed to the first closed position;

[0077] The flushing device is controlled to move toward the sewage outlet until the flushing device abuts against the sewage outlet cover plate, and the sewage outlet cover plate is pushed to the second closing position to close the sewage bucket.

[0078] In practice, if there is a lot of dirt in the sewage bucket, the drainage outlet cover at the bottom of the sewage bucket can be opened first, and the sewage bucket can be drained and flushed in sequence, and then the drainage outlet cover at the bottom of the sewage bucket can be closed. In another embodiment, if there is less dirt in the sewage bucket, after opening the drainage outlet cover at the bottom of the sewage bucket, only the sewage bucket can be drained or flushed directly, and then the drainage outlet cover at the bottom of the sewage bucket can be closed. The specific steps of opening and closing the drainage outlet cover of the sewage bucket can be referred to the control method of the cleaning system mentioned above, and this application will not be repeated here.

[0079] In one embodiment, the switch auxiliary device is arranged on the side of the sewage bucket to move laterally toward the sewage outlet; the flushing device is arranged under the sewage bucket to move longitudinally toward the sewage outlet.

[0080] In one embodiment, the switch auxiliary device includes an upper push rod and a lower push rod; controlling the switch auxiliary device to move toward the sewage outlet of the sewage bucket until the switch auxiliary device abuts against the sewage outlet cover of the sewage bucket, and pushing the sewage outlet cover to the first closed position, including:

[0081] The lower push rod is controlled to move toward the sewage outlet until the lower push rod abuts against the sewage outlet cover plate, and the sewage outlet cover plate is pushed to the first closed position.

[0082] In one embodiment, the switch auxiliary device includes a steering gear; controlling the switch auxiliary device to move toward the sewage outlet of the sewage bucket until the switch auxiliary device abuts against the sewage outlet cover of the sewage bucket, and pushing the sewage outlet cover to the first closed position, including:

[0083] The steering wheel of the steering gear is controlled to rotate toward the sewage outlet until the steering wheel abuts against the sewage outlet cover plate, and the sewage outlet cover plate is pushed to the first closing position.

[0084] In one embodiment, the sewage outlet of the sewage bucket is provided with a lock assembly; pushing the sewage outlet cover to the second closed position to close the sewage bucket includes:

[0085] Push the drain outlet cover to the second closed position so that the locking assembly can lock the drain outlet cover.

[0086] In one embodiment, one end of the drain outlet cover is rotatably fixed to the drain outlet, so that the drain outlet cover is rotatably closed when subjected to the thrust of the switch auxiliary device or the flushing device.

[0087] It should be noted that the method for closing the sewage bucket provided in this application can refer to the control method of the cleaning equipment mentioned above. The implementation principle and the technical effect to be achieved have been discussed above and will not be repeated here.

[0088] Based on the same technical concept, an embodiment of the present application also provides a cleaning system, characterized in that the cleaning system includes a cleaning device and a base station; the cleaning device is provided with a sewage bucket, and the base station is provided with a switch auxiliary device, a flushing device, a controller and a memory; the memory is used to store a computer program, and the controller is coupled to the memory for executing the computer program to implement the method described in any of the above embodiments.

[0089] Based on the same technical concept, an embodiment of the present application also provides a base station for a cleaning device, which is provided with a sewage bucket; the base station includes: a switch auxiliary device, a flushing device, a controller and a memory, the memory is used to store a computer program, and the controller is coupled to the memory for executing the computer program to implement the method described in any of the above embodiments.

[0090] Based on the same technical concept, an embodiment of the present application also provides a computer-readable storage medium, which can store multiple instructions, which are suitable for being loaded by a processor and executing the method described in any of the above embodiments.

[0091] As can be seen from the above, the various technical solutions provided by the present application can decompose the operation of closing the sewage bucket into two parts, the first half of which is performed by the switch auxiliary device, and the second half of which is performed by the flushing device. Compared with the technical solution of using the switch auxiliary device to directly completely close the sewage outlet cover, the travel of the switch auxiliary device when closing the sewage bucket is shortened. Specifically, the sewage outlet cover is first pushed to the first closed position by the switch auxiliary device, so that the sewage outlet cover is in a semi-closed state; and then the sewage outlet cover is pushed to the second closed position by the flushing device, so that the sewage outlet cover reaches a fully closed state. In this way, before the flushing device pushes the sewage outlet cover, the sewage outlet cover will always be in a semi-closed state due to the support of the switch auxiliary device. If the flushing device set on the base station fails to withdraw from the sewage bucket in time for some reason, the sewage outlet cover in a semi-closed state will not clamp the flushing device, thereby avoiding damage to the bottom component of the sewage bucket, ensuring that the cleaning equipment (for example, a handheld floor scrubber) will not be damaged or affected by abnormal operation of the base station.

[0092] Through the description of the above embodiments, those skilled in the art can clearly understand that each embodiment can be implemented by means of software plus a necessary general hardware platform, and of course can also be implemented by hardware. Based on this understanding, the above technical solution is essentially or the part that contributes to the prior art can be embodied in the form of a software product, and the software product of the control method of the cleaning system and / or the method for closing the sewage bucket can be stored in a computer-readable storage medium, such as ROM / RAM, a magnetic disk, an optical disk, etc., including storing a number of instructions for enabling an electronic device to execute the methods described in each embodiment or some parts of the embodiments.

[0093] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application should be included in the protection scope of the present application.
