Abstract
Description
Technical Field
[0001] This application relates to the field of cleaning equipment technology, and in particular to a cleaning system control method and a method for closing a water storage tank. Background Technology
[0002] With the development of technology and the improvement of people's living standards, shopping malls, train stations, hotels, and other commercial areas, as well as more and more families, are beginning to use various cleaning equipment to reduce labor intensity and improve labor efficiency. Among them, floor scrubbers, which combine washing, mopping, and vacuuming functions, can complete deep cleaning of target areas by simply pushing and pulling them by hand, and are widely welcomed by users.
[0003] Floor scrubbers are typically equipped with a base station, which enables automatic cleaning. When the wastewater tank of the floor scrubber needs cleaning, the base station first opens the drain cover of the wastewater tank to discharge the wastewater, then uses the rinsing device installed on the base station to rinse the inner wall of the wastewater tank, and closes the wastewater tank after the rinsing operation is completed.
[0004] However, existing base stations typically insert the flushing device into the wastewater tank through the drain outlet to perform the flushing operation. If the flushing device is not withdrawn from the wastewater tank when the drain outlet cover is closed, the drain outlet cover will be damaged due to severe collision and compression with the flushing device, rendering the entire floor scrubber unusable. Summary of the Invention
[0005] This application provides a base station, a cleaning system, and a control method thereof, which can solve the problem of damage to the opening cover of a water storage tank due to severe collision and compression with a flushing device. To achieve the above objective, the technical solution provided by this application is as follows:
[0006] In a first aspect, this application provides a control method for a cleaning system, the cleaning system including cleaning equipment and a base station; the cleaning equipment is equipped with a water storage tank, and an opening cover is provided on the opening of the water storage tank; the base station is equipped with a first shut-off device and a second shut-off device; the control method includes:
[0007] Control the first closing device to move toward the opening of the water storage tank until the first closing device abuts against the opening cover and pushes the opening cover to the first closed position;
[0008] Control the second closing device to move toward the opening of the water storage tank until the second closing device abuts against the opening cover plate and pushes the opening cover plate to the second closing position to close the water storage tank.
[0009] Secondly, this application provides a method for closing a water storage tank, applied to a base station, wherein the base station includes a first closing device and a second closing device; the method for closing the tank includes:
[0010] Control the first closing device to move toward the opening of the water storage tank until the first closing device abuts against the opening cover of the water storage tank and pushes the opening cover to the first closed position;
[0011] Control the second closing device to move toward the opening of the water storage tank until the second closing device abuts against the opening cover plate and pushes the opening cover plate to the second closing position to close the water storage tank.
[0012] Thirdly, this application provides a cleaning system, which includes cleaning equipment and a base station; the cleaning equipment is equipped with a water storage tank, and the base station is equipped with a switch auxiliary device, a rinsing device, a controller, and a memory; the memory is used to store a computer program, and the controller is coupled to the memory to execute the computer program to implement the method as described in the first aspect.
[0013] Fourthly, this application provides a base station for a cleaning device, the cleaning device being provided with a water storage tank; the base station includes: a switch auxiliary device, a rinsing device, a controller, and a memory, the memory being used to store a computer program, and the controller being coupled to the memory for executing the computer program to implement the method as described in the first or second aspect.
[0014] Fifthly, this application provides a computer-readable storage medium storing a plurality of instructions adapted for loading by a processor and executing the methods described in the first or second aspect.
[0015] As can be seen from the above, the technical solution provided in this application can decompose the operation of closing the water storage tank into two parts. The first part is executed by the first closing device, and the second part is executed by the second closing device. Compared with the technical solution of using the first closing device to directly close the opening cover of the water storage tank completely, the travel distance of the first closing device when closing the water storage tank is shortened. Specifically, the first closing device is first used to push the opening cover to the first closed position, so that the opening cover is in a half-closed state; then the second closing device is used to push the opening cover to the second closed position, so that the opening cover is in a fully closed state. In this way, before the second closing device pushes the opening cover, the opening cover will always be in a half-closed state because it is supported by the first closing device. If the second closing device on the base station fails to retract from the water storage tank in time for any reason, the half-closed opening cover will not jam the second closing device, thereby avoiding damage to the components at the opening of the water storage tank and ensuring that the cleaning equipment (e.g., a handheld floor scrubber) will not be damaged or affected by the abnormal operation of the base station.

[0027] The terms used in this application, such as “above,” “over,” “below,” “under,” “first end,” “second end,” “one end,” and “other end,” indicating spatial relative position, are for illustrative purposes to describe the relationship of one unit or feature relative to another unit or feature as shown in the accompanying drawings. The terms of spatial relative position may be intended to include different orientations of the device in use or operation other than those shown in the figures. For example, if the device in the figures is flipped, a unit described as being “below” or “under” other units or features would be located “above” other units or features. Therefore, the exemplary term “below” can encompass both above and below orientations. The device may be oriented in other ways (rotated 90 degrees or otherwise) and the spatially related descriptive terms used herein shall be interpreted accordingly.
[0028] Furthermore, the terms "installation," "setup," "equipped with," "connection," "sliding connection," "fixed," and "sleeve connection" should be interpreted broadly. 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, components, or parts. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.
[0029] With the development of technology and the improvement of people's living standards, shopping malls, train stations, hotels, and other commercial areas, as well as more and more families, are beginning to use various cleaning equipment to reduce labor intensity and improve labor efficiency. Among them, floor scrubbers, which integrate washing, mopping, and vacuuming functions, can complete deep cleaning of target areas by simply pushing and pulling them by hand, and are widely welcomed by users. Floor scrubbers are generally equipped with a base station, which enables the floor scrubber to clean automatically. When it is necessary to clean the wastewater tank of the floor scrubber, the base station can first open the drain cover of the wastewater tank to discharge the wastewater, and then use the rinsing device set on the base station to rinse the inner wall of the wastewater tank, and close the wastewater tank after the rinsing operation is completed.
[0030] However, existing base stations typically require a flushing device to be inserted into the wastewater tank through its drain outlet for deep cleaning. This flushing operation can include: controlling the flushing device to move towards the drain outlet until it reaches a preset flushing position within the tank; controlling the flushing device to spray liquid to rinse the inner wall of the tank and then discharging the liquid from the drain outlet at the bottom; further controlling the flushing device to reciprocate within the tank for deeper rinsing; and finally, controlling the flushing device to move away from the drain outlet until it exits the tank.
[0031] If the flushing device fails to exit the wastewater tank for various reasons when the drain cover is closed, the drain cover will be damaged due to severe collision and squeezing with the flushing device, thus rendering the entire floor scrubber unusable.
[0032] For example, user Xiaoming used a floor scrubber to thoroughly clean his entire house. When returning the scrubber to the base station for automatic cleaning, due to improper operation and excessive force, the scrubber and base station did not connect accurately, resulting in a collision. This caused some components within the base station to malfunction. When the base station starts working, it controls the flushing device to extend into the wastewater tank and spray liquid to clean it. Normally, after rinsing the wastewater tank, the base station can control the flushing device to retract from the tank and then control the auxiliary device to close the drain outlet cover. However, because some components in the base station related to the flushing and / or tank-closing operations have failed, the flushing device cannot retract properly, and the base station continues to close the drain outlet cover according to a preset program. Shortly after, the drain outlet cover is damaged due to severe collision and compression with the flushing device. Then, the excessive force on the drain outlet cover presses down on the flushing device, jamming it between the drain outlet and the cover, causing the drain outlet to also be deformed.
[0033] Based on this, this application modifies the way the base station closes the wastewater tank of the cleaning equipment. By breaking down the operation of closing the wastewater tank into two parts, the first part uses a switch-assisted device to assist in closing the tank, and the second part uses a flushing device to dominate the closing operation. In this way, even if the flushing device does not exit the wastewater tank in time, the partially closed drain cover will not jam the flushing device, thereby avoiding damage to the bottom components of the wastewater tank.
[0034] The technical solutions in the embodiments of this application will now be clearly and completely described with reference to the accompanying drawings. Obviously, the embodiments described in this application are only a part of the embodiments, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.
[0035] See Figure 1 One embodiment of this application provides a cleaning system including a cleaning device 1 (e.g., a floor scrubber) and a base station 2; the cleaning device 1 is equipped with a water storage tank 11, and the base station 2 is equipped with a first shut-off device 21 and a second shut-off device 22. The control method of this cleaning system includes the following steps:
[0036] S102, control the first closing device to move toward the opening of the water storage tank until the first closing device abuts against the opening cover of the water storage tank and pushes the opening cover to the first closed position.
[0037] The storage tank can be a container that holds liquids, such as a clean water tank, a wastewater tank, or a detergent tank. The storage tank may have an opening, and this opening may be fitted with a cover. The following example uses a wastewater tank as an illustration. When the storage tank is a wastewater tank, the opening can be the wastewater tank's drain outlet, which can be located on the bottom of the wastewater tank to facilitate complete emptying of the wastewater.
[0038] In one embodiment, the first closing device may be an auxiliary device for opening and closing the lid of the water storage tank, such as a conventional lid opening and closing device, and the second closing device may be a rinsing device for rinsing the water storage tank. See also... Figure 2-3 The floor scrubber 1 may include a wastewater tank 11. Typically, users can hand-hold the floor scrubber to clean the target area. After cleaning, the scrubber can be placed at the base station for storage, water filling, wastewater discharge, automatic cleaning, drying, and charging. The base station 2 used in conjunction with the floor scrubber 1 may be equipped with a switch auxiliary device 21 for opening and closing the wastewater tank and a rinsing device 22 for rinsing the inner wall of the wastewater tank.
[0039] In practical applications, when a user uses a handheld floor scrubber to clean a target area, the scrubber draws dirt into a wastewater tank, at which point the wastewater tank's drain cover is fully closed. When it's necessary to drain or rinse the wastewater tank, the scrubber can be connected to a base station. Then, the switch auxiliary device 21 can move towards the wastewater tank's drain outlet. When the switch auxiliary device 21 moves a certain distance from its initial position, it comes into contact with the wastewater tank's drain outlet cover. Continuing to move towards the drain outlet pushes the drain outlet cover to the first closed position, placing it in a semi-closed state.
[0040] S104, control the second closing device to move toward the opening of the water storage tank until the second closing device abuts against the opening cover of the water storage tank, and push the opening cover to the second closed position to close the water storage tank.
[0041] In practical applications, the base station can control the auxiliary device 21 to push the sewage outlet cover to the first closed position. Afterwards, it can also control the flushing device 22 to move towards the sewage outlet. When the flushing device moves a certain distance from its initial position, it will come into contact with the sewage outlet cover. Continuing to move towards the sewage outlet will push the sewage outlet cover to the second closed position, thereby closing the sewage tank.
[0042] Based on this embodiment, this application decomposes the operation of closing the sewage tank into two parts. The first part is performed by the switch auxiliary device, and the second part is performed by the flushing device. Compared with the technical solution of directly closing the sewage outlet cover with the switch auxiliary device, the travel distance of the switch auxiliary device when closing the sewage tank is shortened. Specifically, the switch auxiliary device first pushes the sewage outlet cover to the first closed position, so that the sewage outlet cover is in a semi-closed state; then the flushing device pushes the sewage outlet cover to the second closed position, so that the sewage outlet cover is in 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 action of the switch auxiliary device. If the flushing device installed on the base station fails to withdraw from the sewage tank in time for any reason, the cover in the semi-closed state will not jam the flushing device, thereby avoiding damage to the bottom components of the sewage tank and ensuring that the cleaning equipment (e.g., a handheld floor scrubber) will not be damaged or affected by the 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 tank to a first closed position; the second closing device can move along a second direction to push the opening cover of the water storage tank to a second closed position; wherein the first direction and the second direction are different.
[0044] In implementation, the first and second closing devices can be positioned at different locations on the base station. Correspondingly, the first and second closing devices can move in different directions, cooperating to push the opening cover of the water storage tank to a designated position, completing the tank-closing operation. Thus, the second closing device must be located outside the water storage tank opening for the tank to close successfully. Compared to using a single first closing device to close the water storage tank, this embodiment avoids the second closing device getting stuck at the water storage tank opening during closure. Similarly, it also prevents damage to the equipment caused by various foreign objects, including parts of the cleaning equipment itself, getting stuck at the water storage tank opening during closure.
[0045] In one embodiment, the switch auxiliary device may be located on the side of the sewage tank to move laterally toward the sewage outlet; the flushing device may be located below the sewage tank to move longitudinally toward the sewage outlet.
[0046] In implementation, the switch auxiliary device can move laterally toward the drain outlet. This allows it to exert a lateral pushing force on the drain outlet cover when the tank is closed. During this lateral movement, the switch auxiliary device's trajectory intersects with the drain outlet cover in its first closed position. This ensures that the switch auxiliary device maintains continuous contact with the drain outlet cover and pushes it laterally during the tank-closing operation.
[0047] It is worth mentioning that when the drain cover moves to the first closed position, the switch auxiliary device no longer needs to move towards the drain. At this time, the switch auxiliary device can connect with the drain cover and support it.
[0048] In one embodiment, the first closed position can be determined based on the travel distance of the switch auxiliary device. For example, the switch auxiliary device can move laterally (to the left in the embodiment shown in the figure) about 23 cm toward the drain outlet, causing the drain outlet cover to move to the first closed position.
[0049] Furthermore, after the drain cover moves to the first closed position, the flushing device can move longitudinally toward the drain (upward in the embodiment shown in the attached figure). This allows the flushing device to exert a longitudinal pushing force on the drain cover when closing the tank. After moving approximately 6 centimeters, the flushing device pushes the drain cover to the second closed position. During the longitudinal movement of the flushing device toward the wastewater tank, its trajectory can intersect with the drain cover located in the first closed position. This ensures that the flushing device continuously contacts and longitudinally pushes the drain cover when performing the tank-closing operation.
[0050] It is understood that the dimensions of the floor scrubber, base station, and its various components can be configured according to actual needs. Therefore, the range of distances that the auxiliary switching device and the flushing device can move toward the drain outlet can also be set according to actual needs. This application does not impose any restrictions on this.
[0051] In one embodiment, the first closed position can also be determined based on its positional relationship with any component. For example, the angle between the first closed position and the plane of the sewage tank outlet can be approximately 90°. Of course, the dimensions, assembly positions, and relationships of the floor scrubber, base station, and their various components can be configured according to actual needs, so the angle between the first closed position and the plane of the sewage tank 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 of the flushing device can intersect the plane of the sewage outlet cover located in the first closed position. This ensures that the flushing device can abut against the sewage outlet cover and push the sewage outlet cover to close completely during its longitudinal movement toward the sewage outlet.
[0052] In one implementation, see [link to implementation details]. Figure 4 The switch auxiliary device 21 may include an upper push rod 211 and a lower push rod 212. The upper push rod 211 can be used to open the sewage outlet cover 112 of the sewage tank, and the lower push rod 212 can be used to close the sewage outlet cover 112 of the sewage tank. Based on this structure, step S102 may specifically include: controlling the lower push rod to move towards the sewage outlet until the lower push rod abuts against the sewage outlet cover, and pushing the sewage outlet cover to the first closed position.
[0053] In implementation, the switching auxiliary device may further include a gear 213 disposed between the upper push rod 211 and the lower push rod 212. The gear 213 can mesh with the gear 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 its built-in motor, the movements of the upper push rod 211 and the lower push rod 212 are exactly opposite. Based on this structure, during the tub closing operation, the movement of the switching auxiliary device toward the drain outlet can be understood as the lower push rod 212 moving toward the drain outlet 111. During the tub opening operation, the movement of the switching auxiliary device toward the drain outlet can be understood as the upper push rod 211 moving toward the drain outlet 111.
[0054] Based on this embodiment, the upper and lower push rods can be driven by a single gear, eliminating the need for two separate drive mechanisms. Therefore, the switch auxiliary device provided in this application has a simple structure and saves hardware costs.
[0055] In another embodiment, the switch auxiliary device may be a servo motor. Accordingly, step S102 may specifically include: controlling the servo motor's rudder to rotate toward the drain outlet until the rudder abuts against the drain outlet cover, and pushing the drain outlet cover to the first closed position.
[0056] See also Figure 8 The servo motor 21 typically includes a servo disc 212-1 and a rotating shaft 213-1. It is understood that the servo disc 212-1 can be used to abut against the drain cover 112 to push the drain cover 112. When controlling the servo motor 21 to close the sewage tank 11, i.e., to close the drain cover 112 of the sewage tank 11, the servo disc 212-1 can be rotated towards the drain outlet 111 of the sewage tank (shown as clockwise rotation in the diagram) by controlling the rotating shaft 213-1 of the servo motor until the servo disc 212-1 abuts against the drain cover 112, pushing the drain cover 112 to the first closed position.
[0057] See below Figure 9 The flushing rod 221 of the flushing device 22 can move toward the drain port 111 under the drive of the stepper motor until the flushing rod 221 abuts against the drain port cover 112 and pushes the drain port cover 112 to the second closed position to close the sewage tank 11.
[0058] In one embodiment, to reduce structural complexity and simplify the opening and closing of the sewage tank, both opening and closing operations can be performed by a single servo motor. Accordingly, Figure 5-7 The locking assembly on the drain outlet 111 of the sewage tank shown can be the female latch of a spring-loaded push-button switch, and the protrusion on the drain outlet cover 112 can be the male latch of a spring-loaded push-button switch. In this way, the drain outlet cover can be opened with a single press and locked with another press.
[0059] Based on this structure, when it is necessary to open or close the drain cover 112, the servo motor can be controlled to drive the servo disc to move towards the drain outlet of the sewage tank and abut against the drain cover 112. (See also...) Figure 10 The locked male and female latches (not shown in the figure) can be released by pressing. At this time, the servo motor can be reversed to reset them, thereby opening the drain cover 112. When it is necessary to close the opened drain cover 112, the servo motor can be controlled to drive the servo disk toward the drain and push the drain cover 112 to the first closed position. Then, the flushing rod 221 of the flushing device 22 is controlled to push the drain cover 112 to the second closed position. At this time, the separated male and female latches can be locked by pressing.
[0060] It is worth mentioning that, in order to ensure the airtightness of the sewage tank's discharge port, a sealing gasket can be installed on the discharge port or its cover, so that the discharge port cover can make tight contact with the discharge port when closed, preventing sewage leakage. Furthermore, in order to provide pressing space for the spring-loaded switch, the sealing gasket can be made of a compressible elastic material, such as rubber.
[0061] Based on this implementation method, the servo motor saves space and has a simpler structure compared to the laterally extended double push rod structure. Furthermore, a single servo motor can perform both the opening and closing operations of the bucket, reducing the complexity of the bucket opening and closing process.
[0062] It is worth mentioning that when the locking assembly uses a spring-loaded push switch, the flushing device can also press the closed drain cover upwards to open it. However, the wastewater tank of the floor scrubber typically only needs to have its drain cover opened for wastewater discharge and / or flushing operations when it is full of dirt. When there is a lot of dirt in the wastewater tank, the dirt will exert significant pressure on the drain cover at the bottom of the tank due to gravity. At this time, a large pushing force is required to open the drain cover to open the spring-loaded push switch. Therefore, if the flushing device is used to open the drain cover, it requires a high level of power. Insufficient power may prevent the drain cover from opening, or the drain cover may be damaged by the pressure of the dirt, causing it to suddenly strike the flushing device downwards. Therefore, in a preferred embodiment, a lateral pushing force can be applied to the drain cover to open it, or a suitable servo motor can be used to press and open the drain cover at the bottom of the wastewater tank. The model and specifications of the servo motor can be selected as needed, 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 tank is in the first closed position, the movement paths of the first closing device and the second closing device are separate.
[0064] In practice, when the first closing device pushes the opening cover of the water storage tank to the first closed position, the second closing device can begin the latter part of the tank-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 towards the opening of the water storage tank, which may damage the first closing device and other components. This embodiment controls the movement distance of the first closing device, ensuring that the second closing device can contact the drain cover during its movement towards the opening of the water storage tank, while ensuring that the position of the first closing device does not exceed the movement path of the second closing device when the opening cover of the water storage tank is pushed to the first closed position, thereby preventing the second closing device from colliding with the first closing device during its movement.
[0065] In one implementation, 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 move the flushing rod 221 toward the drain outlet 111 until the flushing rod 221 abuts against the drain outlet cover 112, and pushing the drain outlet cover 112 to the second closed position to close the sewage tank 11.
[0066] In practice, the sewage tank needs to be opened before flushing it. Accordingly, the control method of the above-mentioned cleaning system may also include a tank opening step, specifically: before performing the flushing operation on the sewage tank, control the upper push rod to move towards the drain outlet until the upper push rod abuts against the drain outlet cover to open the drain outlet cover.
[0067] In one embodiment, a drain cover is rotatably fixed to one side of the sewage tank's drain outlet, and a locking assembly is correspondingly provided on the other side of the sewage tank's drain outlet. Accordingly, step S104 may specifically include: pushing the drain cover to a second closed position so that the locking assembly locks the drain cover.
[0068] See Figure 5-7 The sewage tank 11 may also be equipped with a latch 1111 and a release rod 1112 on the sewage outlet 111. The sewage outlet cover 112 has a protrusion 1121 (which may be called a male latch) for the latch 1111 (which may be called a female latch) to engage. The release rod 1112 extends from the position of the latch 1111 to the side of the sewage outlet 111 adjacent to the upper push rod 211.
[0069] See Figure 5When the drain cover 112 is closed, the upper push rod 211 can move laterally to abut against the release link 1112 provided on the drain 111. When the upper push rod 211 abuts against the action area of the release link 1112, it can cause the release link 1112 to move (moving to the left in the embodiment shown in the attached figure). In this way, the release link 1112 will further push the latch 1111 to move, so that the latch 1111 and the protrusion 1121 are no longer engaged, and the latch 1111 disengages from the drain cover 112, thus opening the drain cover 112 of the sewage tank. A schematic diagram of the open state of the drain cover 112 can be found in [reference needed]. Figure 6 .
[0070] Based on this embodiment, the drain cover can be locked using the locking assembly, keeping the wastewater tank of the floor scrubber in a closed state. Furthermore, once the drain cover is locked, the wastewater tank can be easily opened by pushing the release lever. In other words, the cleaning system and control method provided in this application ensure safe and reliable tank closure and convenient and quick tank opening.
[0071] It is worth mentioning that the upper push rod 211 can move laterally away from the drain outlet after the drain outlet cover is opened, and its movement distance is at least sufficient to ensure that the upper push rod 211 no longer abuts against the release link 1112. Correspondingly, the release link 1112 can move to the right under the action of the spring, thereby resetting the latch 1111.
[0072] In one embodiment, to ensure that the drain outlet cover can move under the thrust of the switching auxiliary device or the flushing device, one end of the drain outlet cover can be rotatably fixed to the drain outlet. This allows the drain outlet cover to rotate open or close when subjected to the thrust of the switching auxiliary device or the flushing device.
[0073] In practice, one side of the drain cover 112 can be rotatably connected to the drain outlet side via a C-shaped limiting member. Of course, the drain cover 112 and the drain outlet 111 can also be hinged, or other movable connection methods can be used, which are not limited in this application.
[0074] In one embodiment, after the floor scrubber performs certain cleaning tasks, there is no need to rinse the wastewater tank; only a drain operation is performed to remove the dirt from the tank. Accordingly, after opening the wastewater tank's drain cover and emptying the tank, the auxiliary switch can be controlled to push the drain cover to a first closed position, and the rinsing device can be controlled to push the drain cover from the first closed position to a second closed position to close the wastewater tank's drain cover. A schematic diagram of the drain cover 112 in the first closed position (i.e., in a semi-closed state) can be found [reference needed]. Figure 7 .
[0075] Based on the same inventive concept, an embodiment of the present application further provides a new method for closing a sewage bucket, which can be applied to a base station supporting a cleaning device. The base station may include a switch assisting device and a flushing device; the method for closing the bucket may include:
[0076] After the dirt in the sewage bucket is emptied, control the switch assisting device to move towards the sewage outlet of the sewage bucket until the switch assisting device abuts against the sewage outlet cover plate of the sewage bucket, and push the sewage outlet cover plate to the first closed position;
[0077] Control the flushing device to move towards the sewage outlet until the flushing device abuts against the sewage outlet cover plate, and push the sewage outlet cover plate to the second closed position to close the sewage bucket.
[0078] In practice, if there is a lot of dirt in the sewage bucket, the sewage outlet cover plate at the bottom of the sewage bucket can be opened first, and the sewage discharging operation and the flushing operation are sequentially performed on the sewage bucket, and then the sewage outlet cover plate at the bottom of the sewage bucket is closed. In another embodiment, if there is less dirt in the sewage bucket, after opening the sewage outlet cover plate at the bottom of the sewage bucket, only the sewage discharging operation or the flushing operation can be performed directly on the sewage bucket, and then the sewage outlet cover plate at the bottom of the sewage bucket is closed. The specific steps for opening and closing the sewage outlet cover plate of the sewage bucket can be referred to the control method of the cleaning system described above, and the present application will not elaborate here.
[0079] In one embodiment, the switch assisting device is arranged on the side of the sewage bucket to move horizontally towards the sewage outlet; the flushing device is arranged below the sewage bucket to move vertically towards the sewage outlet.
[0080] In one embodiment, the switch assisting device includes an upper ejector rod and a lower ejector rod; controlling the switch assisting device to move towards the sewage outlet of the sewage bucket until the switch assisting device abuts against the sewage outlet cover plate of the sewage bucket and pushing the sewage outlet cover plate to the first closed position includes:
[0081] Control the lower ejector rod to move towards the sewage outlet until the lower ejector rod abuts against the sewage outlet cover plate and push the sewage outlet cover plate to the first closed position.
[0082] In one embodiment, the switch assisting device includes a servo motor; controlling the switch assisting device to move towards the sewage outlet of the sewage bucket until the switch assisting device abuts against the sewage outlet cover plate of the sewage bucket and pushing the sewage outlet cover plate to the first closed position includes:
[0083] Control the steering wheel of the servo motor to rotate towards the sewage outlet until the steering wheel abuts against the sewage outlet cover plate and push the sewage outlet cover plate to the first closed position.
[0084] In one embodiment, a locking component is arranged at the sewage outlet of the sewage bucket; pushing the sewage outlet cover plate to the second closed position to close the sewage bucket includes:
[0085] Push the drain cover to the second closed position so that the locking assembly locks the drain cover.
[0086] In one embodiment, one end of the drain cover is rotatably fixed to the drain outlet, such that the drain cover rotates to close 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 tank provided in this application is similar to the control method of the cleaning equipment described above. The implementation principle and the desired technical effect have been discussed above and will not be repeated here.
[0088] Based on the same technical concept, this application also provides a cleaning system, characterized in that the cleaning system includes cleaning equipment and a base station; the cleaning equipment is equipped with a wastewater tank, and the base station is equipped 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 to execute the computer program to implement the method described in any of the above embodiments.
[0089] Based on the same technical concept, this application embodiment also provides a base station for a cleaning device, the cleaning device being equipped with a wastewater tank; the base station includes: a switch auxiliary device, a flushing device, a controller, and a memory, the memory being used to store a computer program, and the controller being 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, embodiments of this application also provide a computer-readable storage medium that can store multiple instructions adapted for loading by a processor and executing the methods described in any of the above embodiments.
[0091] As can be seen from the above, the technical solutions provided in this application can decompose the operation of closing the sewage tank into two parts: the first part is executed by the switch auxiliary device, and the second part is executed by the flushing device. Compared with the technical solution of directly closing the sewage outlet cover with the switch auxiliary device, the travel distance of the switch auxiliary device when closing the sewage tank 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; then the flushing device is used to push the sewage outlet cover to the second closed position, so that the sewage outlet cover is in 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 because it is supported by the switch auxiliary device. If the flushing device installed on the base station fails to withdraw from the sewage tank in time for any reason, the sewage outlet cover in the semi-closed state will not jam the flushing device, thereby avoiding damage to the bottom components of the sewage tank and ensuring that the cleaning equipment (e.g., a handheld floor scrubber) will not be damaged or affected by the abnormal operation of the base station.
[0092] Through the above description of the embodiments, those skilled in the art can clearly understand that each embodiment can be implemented by means of software plus necessary general-purpose hardware platforms, and of course, it can also be implemented by hardware. Based on this understanding, the above technical solutions, in essence or the parts that contribute to the prior art, can be embodied in the form of software products. The software products of the control method of the cleaning system and / or the method of closing the sewage tank can be stored in a computer-readable storage medium, such as ROM / RAM, magnetic disk, optical disk, etc., including storing several instructions to cause an electronic device to execute the methods described in various embodiments or some parts of the embodiments.
[0093] The above description is only a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
