Detailed Description

In order to make the technical solutions better understood by those skilled in the art, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.

In some of the flows described in the specification, claims, and above-described figures of the present application, a number of operations are included that occur in a particular order, and these operations may be performed out of order or in parallel as they occur herein. The sequence numbers of the operations, e.g., 101, 102, etc., are merely used to distinguish between the various operations, and the sequence numbers themselves do not represent any order of execution. Additionally, the flows may include more or fewer operations, and the operations may be performed sequentially or in parallel. It should be noted that, the descriptions of "first", "second", etc. in this document are used for distinguishing different structures, components, units, etc., and do not represent a sequential order, nor limit the types of "first" and "second" to be different. Moreover, the described embodiments are only some of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The application relates to a cleaning device is a device with a water storage barrel and capable of recycling cleaning sewage to the water storage barrel, such as a cleaning machine and a water-spraying type sweeping robot. The operating modes of this type of cleaning device are: spraying clean water to clean the ground, carpet or plane (such as table top), and recovering the sewage generated by cleaning with a cleaning device (such as a rolling brush) to the water storage barrel. Generally, such cleaning equipment has two water storage tanks, one for storing clean water or clean cleaning solution, which may be called a clean water tank; and the other is used for storing the recovered sewage and can be called a sewage bucket. In the working process, the clear water tank of the cleaning equipment cannot be automatically added with water, once the water in the clear water tank is used up, the cleaning equipment can interrupt the work and give an alarm to prompt a user to add water in time; similarly, when the sewage bucket of the cleaning device is full, the work can be interrupted and an alarm can be given to prompt a user to pour out sewage in time. And because of the design requirement of light weight of the cleaning machine, the capacity of the water storage barrel of the existing cleaning equipment cannot be designed to be large. This means that the user needs to frequently add water into the clean water tank and pour out the sewage in the sewage tank. The larger the cleaning area is, the more obvious the problems of frequent water adding and water pouring are. For example, a user uses a cleaning device to clean a place, the volume of the clean water barrel and the sewage barrel is small and the clean water barrel is half, the clean water barrel needs to be taken down to be added with water, and the user can pour the water in the sewage barrel along the belt in order to avoid running for a long time. If a place (such as a toilet) where water is added or poured needs to pass through a place which is just cleaned, the cleaned place may be stepped on due to unclean soles.

To this end, the present application provides the following embodiments to solve or improve the problems in the prior art.

Fig. 1 is a schematic structural diagram of a self-drawn water recycling system according to an embodiment of the present disclosure. As shown in fig. 1, the self-drawn water recycling system includes: a water storage barrel 1 and a self-water-drawing device 2. The self-water-drawing device 2 has the capability of drawing water and purifying water automatically; at least part of the water self-drawing device 2 is disposed in the water storage barrel 1, and actively draws, purifies the water in the water storage barrel 1 and discharges the water from the water outlet end 22 of the water self-drawing device 2, so as to be used when the cleaning device works. More specifically, as shown in fig. 1, the purified water discharged from the outlet end of the water scooping device 2 can be used by a cleaning device 3 of a cleaning apparatus. The cleaning device 3 may be a rag, a rolling brush, etc., and this embodiment is not particularly limited thereto.

The 'water drawing' is to absorb water and pump water from bottom to top. The autonomous water drawing in the embodiment can be understood as follows: and the water is actively absorbed without external force. Accordingly, the self-watering device in the present embodiment refers to a member or assembly having hydrophilicity and the ability to self-lubricate and self-lubricate, and is capable of self-watering and self-watering a liquid in contact therewith without external force or action.

In practice, as shown in the enlarged partial view of fig. 1, the water self-drawing device 2 may include a plurality of hollow capillary tubes. In fig. 1, a plurality of micropores are arranged in an array on the tube wall, and water enters the tube from the tube wall 21 of the hollow capillary tube and flows along the hollow capillary tube to the water outlet end 22.

The capillary tube is made of a hydrophilic material, and the hydrophilic material is not particularly limited herein. The plurality of capillary tubes may be in the form of a cylinder, a plate, an annular cylinder, or the like.

In other embodiments, the water self-drawing device 2 may be a sponge-like porous structure.

In practical implementation, the self-priming device in this embodiment may be made of a hydrophilic material in a capillary shape (specifically, for example, a hydrophilic hollow fiber membrane tube) to generate self-priming capability, and the material is made into a porous form to realize the capability of priming water from the outside of the capillary tube to the inside of the capillary tube, and the filtering effect of the self-priming device may be controlled by selecting porous materials with different pore sizes. As shown in fig. 1, after the hydrophilic and porous material of the self-watering device contacts with the sewage, impurities of the sewage are blocked outside the self-watering device due to the hydrophilic effect and the porosity of the self-watering device, clean water enters the self-watering device, and under the capillary action of the capillary tube of the self-watering device and the hydrophilic effect of the hydrophilic material, self-pressure fluidity is formed, so that the sewage is continuously changed into clear water and is pumped (overcoming gravity, from bottom to top).

In the present embodiment, the capillary phenomenon (also called capillary action) refers to a phenomenon that liquid rises inside a thin tubular object due to the difference between cohesion and adhesion to overcome gravity. The capillary tube is inserted into water, and the liquid level in the tube rises to be higher than that outside the tube. For example, the cotton threads in the wick are interwoven, the fibers in the paper towel are mutually staggered, the wood fibers in the trunk are densely developed, the materials or physiological structures form capillaries, and liquid such as water, oil and the like can overcome the gravity of the earth under the action of the capillaries and gradually rise along the materials.

The technical scheme that this embodiment provided adopts the water of swabbing oneself device can realize carrying out filterable effect to the water in the water storage bucket. The self-water-drawing device has a capillary phenomenon and a hydrophilic phenomenon, under the action of a capillary action force and a hydrophilic action force, water in the sewage at the outer side needs to pass through a plurality of tiny micropores on the self-water-drawing device, the tiny micropores only allow water and small molecular substances to pass through, and substances with the volume larger than the micropore diameter in the sewage are intercepted at the outer side of the self-water-drawing device, so that the purposes of purifying and separating the sewage and the like are achieved.

For example, the water self-drawing device comprises a hollow fiber membrane tube made of hydrophilic material, and the tube wall 21 of the hollow fiber membrane tube is provided with a large number of micropores (see the enlarged partial view in fig. 1) with the diameter less than 1 micron, and can filter fine suspended matters with the diameter more than 0.1 micron. The hollow fiber tubes can sieve solute molecules with the diameter smaller than the aperture from sewage, and separate particles with the molecular weight larger than 500 daltons and the particle size larger than 2-20 nanometers. The moisture drawn by the plurality of hollow fiber tubes may be provided to the cleaning device for use.

In this embodiment, the water self-pumping device 2 may be a flexible structure, as shown in fig. 1, the water self-pumping device 2 may be partially disposed in the water storage barrel 1, and the rest is disposed outside the water storage barrel 2. The self-water-drawing device 2 can be lapped on the wall of the water storage barrel 1. In this embodiment, the self-scooping device may be disposed in the water storage barrel in any one of the following manners.

In the first mode, the self-water-drawing device is connected with a barrel cover of the water storage barrel.

As shown in fig. 2, a mounting hole 102 is formed in a lid 101 of the water storage bucket 1, and the mounting hole 102 is adapted to a mounting portion of the self-watering device 2. The installation part of the water self-drawing device 2 can be fixed in the installation hole 102 by means of the thread or interference fit, so that the water self-drawing device 2 is arranged in the water storage barrel 1.

For example, as shown in fig. 2, the self-watering device 2 is a flexible structure, and naturally hangs down and is disposed at the bottom of the water storage barrel 1, and the redundant part is naturally disposed at the bottom of the water storage barrel 1. If the density of the material of the water self-drawing device 2 is less than that of water, the water self-drawing device 2 can be in a floating state in the water storage tank 1. Or, as shown in fig. 3, the water drawing device 2 vertically extends into the water storage barrel 1, and a certain gap D is formed between the bottom of the water drawing device 2 and the bottom of the water storage barrel 1. Because the large granule impurity of aquatic can automatic precipitation in the water storage bucket 1, if from swabbing

water device

2 and 1 bottom butt of water storage bucket, the large granule can remain the accumulation and 2 bottom surfaces at the device of swabbing water, and then leads to 2 bottoms of device of swabbing water to block up.

In another implementation, the water self-drawing device 2 may be integrated with the lid 101 of the water storage barrel 1.

After a user uses a cleaning apparatus including the self-drawing water recycling system provided in this embodiment for a period of time, the user wants to clean the self-drawing water recycling system. A user can detach the water storage barrel 1 from the machine body of the cleaning equipment, then take down the barrel cover 101 of the water storage barrel 1, directly hold the barrel cover 101 and clean the self-watering device 2 under a faucet; the inside of the water storage barrel 1 can be cleaned. Of course, when the self-pumping device 2 is detachably connected to the barrel cover 101, the self-pumping device 2 may be detached from the barrel cover 101 and then separately flushed.

In the second mode, the self-water-drawing device is connected with the wall or the bottom of the water storage barrel.

As shown in fig. 4a and 4b, the bottom of the water storage barrel 1 is provided with a fixing base 300. The fixing base 300 can be integrated with the water storage barrel 1, for example, the water storage barrel 1 is a plastic barrel, and the water storage barrel 1 containing the fixing base 300 in the barrel can be obtained by one-time injection molding through an injection molding process. Alternatively, the fixing base 300 is fixed to the bottom of the water storage barrel 1 by an adhesive manner, or the fixing base 300 is connected to the bottom of the water storage barrel 1 by a fastening or other connecting structure, which is not limited in this embodiment.

As shown in fig. 4a and 4b, the fixing base 300 includes a supporting member 301 extending upward from the bottom of the tub, and a mounting base 302 at the top of the supporting member. The mounting base 302 is provided with a mounting hole 102, and the mounting hole 102 is adapted to the mounting portion of the self-watering device 2. The mounting portion of the water self-pumping device 2 may be connected to the mounting hole 102 by a thread or an interference fit.

A sealing ring can be arranged between the mounting part of the self-tapping device and the mounting hole 102.

Wherein, the supporting member 301 can be implemented by various structures. For example, support member 301 may include a plurality of posts; or the supporting member 301 is a supporting barrel (as shown in fig. 4a and 4b), the supporting barrel may be provided with a plurality of through holes, and the liquid in the water storage barrel 1 can enter the supporting barrel through the through holes, so as to draw the water from the water drawing device 2.

In specific implementation, the through hole on the supporting barrel can be properly reduced, so that the supporting barrel can be used as a filtering component, liquid in the water storage barrel 1 is filtered once through the supporting barrel, and then the water is sucked by the self-water sucking device 2.

Fig. 5 shows a scheme that the water self-drawing device 2 is connected with the wall of the water storage barrel 1. Referring to fig. 5, a through hole is formed in the wall 103 of the water storage bucket 1. The through hole is provided with a connecting structure 104 matched with the mounting part of the self-water-drawing device 2. Specifically, the connecting structure 104 protrudes outward from the barrel wall 103 to form a mounting opening matched with the mounting portion. The self-tapping device 2 can be installed at the installation opening through threads or interference fit and the like, and is sealed with the installation opening through a sealing ring 105.

In the solution shown in fig. 5, the installation position of the water self-scooping device 2 is relatively low, and in fact, the water self-scooping device 2 may also be installed at a higher position of the tub wall 103. The larger impurities in the water storage barrel 1 sink under the action of gravity, and the self-water-drawing device 2 is positioned on the upper clean layer to draw water.

If the self-watering device 2 is a flexible structure and the material density is less than the density of the liquid in the water storage tank, as shown in fig. 5, the flexible self-watering device 2 can float in the liquid in the water storage tank 1 under the action of buoyancy.

Still alternatively, as shown in fig. 6, in another implementation scheme, the fixing seat 300 is disposed on the wall 103 of the water storage bucket 1. The structure of the fixing base 300 is the same as that shown in fig. 4 b. The fixing base 300 and the barrel wall 103 can be integrated into a whole, for example, the water storage barrel 1 is made of plastic, and the water storage barrel 1 with the fixing base 300 on the barrel wall 103 can be directly injection molded in an injection molding process. In order to facilitate the installation of the self-pumping device 2, an extended installation opening is formed on the outer side of the barrel wall 103, and the installation opening is matched with the installation position of the self-pumping device 2.

The portion of the fixing base 300 in fig. 6, which is located inside the water storage tub, may be referred to as a supporting member. As described above, the supporting member may include a plurality of pillars, or the supporting member may be a supporting barrel, and the supporting barrel may be provided with a plurality of through holes, through which the liquid in the water storage barrel 1 can enter the supporting barrel, so that the self-pumping device 2 can pump and purify the water. In specific implementation, the through hole on the supporting barrel can be properly reduced, so that the supporting barrel can be used as a filtering component, liquid in the water storage barrel is filtered once through the supporting barrel, and then the water is sucked by the self-water sucking device 2.

In the solutions shown in fig. 5 and 6, the self-pumping device is installed in the water storage barrel from the outside, and the sealing ring is used for sealing at the installation opening, so that the installation is simple, reliable sealing can be realized, and the self-pumping device can be conveniently disassembled, cleaned and replaced. When a user uses the cleaning equipment comprising the self-pumping water recycling system shown in the figures 5 and 6, the user can directly take the self-pumping device from the wall of the water storage barrel for observation without dismounting the water storage barrel, and confirm whether the self-pumping device needs to be cleaned or replaced, so that the use efficiency of the cleaning equipment is improved.

The self-water-drawing device 2 is fixedly arranged in the water storage barrel 1 by adopting the modes of figures 2, 3, 4a, 4b, 5, 6 and the like, the structure is firmer, and the cleaning equipment cannot shake left and right in the operation process. When the water storage barrel 1 is cleaned, the self-pumping device 2 can be detached from the barrel cover 101, the fixing seat 300 or the barrel wall 103 for cleaning, so that the residue of stains and odor is reduced, the breeding of bacteria is reduced, and the service life can be effectively prolonged. When the service life of the self-pumping device 2 is reached, the self-pumping device 2 can be replaced through simple disassembly and assembly steps, and the use cost of a user is reduced.

In a third mode, the self-water-drawing device floats in the liquid in the water storage barrel.

The density of the material of the self-water-drawing device 2 is less than that of the liquid in the water storage barrel 1. As shown in fig. 7, the self-watering device 2 is directly placed in the water storage barrel 1, and due to the buoyancy, the self-watering device 2 can float in the liquid in the water storage barrel 1. After the self-water-drawing device 2 floats on the liquid in the water storage barrel 1, the self-water-drawing device 2 can still be contacted with the liquid in the water storage barrel. When the self-water-drawing device is partially contacted with water, the water can be automatically drawn from the contacted liquid. For the cleaning equipment with the posture of the cleaning equipment affecting the posture of the water storage barrel 1 due to the posture change, the self-water-drawing device 2 floats in the water storage barrel 1, so that the self-water-drawing device 2 can always be in contact with the liquid in the water storage barrel 1 when the posture of the water storage barrel 1 is changed.

Further, referring to fig. 1 to 8, the self-drawing water recycling system provided in this embodiment may further include a connector 4, where the connector 4 is used to mount the self-drawing water device 2 on a corresponding component or a mounting port, and may further be connected to a water outlet pipe, so as to guide the water discharged from the water outlet end 22 of the self-drawing water device 2 to a corresponding position, which is convenient for the cleaning device to use. The connector 4 may serve as a mounting site for the water self-pumping device 2 mentioned above. Specifically, referring to fig. 8, the connector 4 is provided with a water drawing cavity 203 and a water outlet pipe 204. The connecting member 4 is disposed at the water outlet end 22 of the water self-scooping device 2, the scooping chamber 203 is communicated with the water outlet end 22, and the liquid entering the scooping chamber 203 from the water outlet end 22 is discharged through the water outlet pipe 204.

Referring to fig. 5 and 6, in an example where a through hole is formed in the wall 103 of the water storage barrel 1, the self-pumping device 2 enters the barrel of the water storage barrel 1 through the through hole, and the connecting member 4 is located outside the water storage barrel 1 and sealed at the through hole. Referring to fig. 4a and 4b, an example of the structure of the fixing base 300 is provided in the water storage bucket 1, and the connecting piece 4 is sealed with the mounting base 302 on the fixing base 300.

Referring to the water storage barrel 1 with the structure shown in fig. 9a, the barrel bottom of the water storage barrel 1 is provided with a liquid inlet pipeline 6 for introducing liquid into the barrel. For a water storage bucket 1 of this type of structure; the water self-scooping apparatus 2 may be provided in two ways as shown in fig. 9a and 10 a. As shown in fig. 9a and 9b, the self-tapping device 2 is annular and surrounds the outer periphery of the liquid inlet pipe 6. Alternatively, as shown in fig. 10a and 10b, the number of the self-scooping devices 2 is plural, and the plural self-scooping devices 3 surround the outer periphery of the liquid inlet pipe 6. The two self-water-drawing devices are annularly arranged around the liquid inlet pipeline 6, so that the limited space between the liquid inlet pipeline 6 and the barrel wall 103 can be fully utilized, and the flow of self-water-drawing is obviously improved under the condition of not changing the volume of the water storage barrel 1.

The flow rate drawn by the self-water-drawing capability of the self-water-drawing device is relatively small, so that the self-water-drawing capability can be improved by increasing the amount of water-drawing material, such as the number of capillary tubes, in the specific implementation. Alternatively, a pressurizing device, such as the first pump 5 shown in fig. 1 to 6, is added to improve the self-pumping capability of the self-pumping device. The first pump 5 may be a water pump or an air pump. The first pump 5 is communicated with a water outlet end 22 of the water self-drawing device 2, and is used for assisting the water self-drawing device 2 to draw water in the water storage barrel 1.

In an achievable technical solution, as shown in fig. 11a and 11b, at least one partition plate 8 is arranged in the water storage barrel 1; the at least one partition 8 divides the water storage bucket 1 into at least two bucket zones 106. The bottoms of the barrel regions 106 are not in communication. The height of the at least one partition plate 8 is lower than the height of the wall of the water storage barrel 1. The at least two barrel zones include an upstream barrel zone and a downstream barrel zone. And the liquid in the upstream barrel area enters the downstream barrel area after exceeding the height of the partition plate. At least one midstream barrel zone can be arranged between the upstream barrel zone and the downstream barrel zone. The self-water-drawing device 2 is arranged in the downstream barrel area.

As shown in fig. 11a, the water storage tank 1 has two tank areas 106, the right tank area 106 in fig. 11a is provided with the self-pumping device 2, and the left tank area 106 is not provided with the self-pumping device 2. For convenience of description, a barrel region where the self-watering device 2 is not provided is referred to as an upstream barrel region (or a raw liquid barrel region); the barrel zone provided with the self-watering device 2 is referred to as a downstream barrel zone (or filter barrel zone). Get into the sewage of water storage bucket 1 can advance into upper reaches bucket district (or former liquid bucket district), and the bottom of upper reaches bucket district is deposited to the great granule in the sewage under the effect of gravity, and the upper strata surpasss the baffle is crossed from 8 tops of baffle to the liquid of 8 heights of baffle and is got into low reaches bucket district. Fig. 11b shows the case where two partitions 8 are provided in the water storage tub, and the two partitions 8 divide the water storage tub into three tub areas 106. Assuming that the sewage enters the left barrel region of the three barrel regions 106 in fig. 11b, the three barrel regions 106 can be respectively as follows from left to right according to the flowing direction of the liquid: an upstream barrel zone, a midstream barrel zone and a downstream barrel zone (i.e. the right barrel zone in fig. 11 b). The water self-drawing device 2 may be disposed in a downstream one of the three tub sections 106. In addition, it should be added that the height of the partition 8 can be gradually decreased in the upstream and downstream directions of the liquid flow in the specific implementation. As shown in fig. 11b, the height of the partition between the upstream barrel region and the midstream barrel region can be higher than that between the midstream barrel region and the downstream barrel region.

As can be seen from fig. 11a and 11b, the partition 8 performs a primary filtering function on the sewage, the liquid which does not contain larger impurities and whose upper layer exceeds the height of the partition 8 passes through the partition and enters the downstream barrel region, and the liquid entering the downstream barrel region is pumped by the self-pumping device 2 to purify the water. This helps to extend the life of the self-tapping device.

The self-sucking water recycling system provided by the embodiment can be used for robots with cleaning functions, vertical cleaning machines, handheld cleaning machines and the like, is provided with the water storage barrel, and can recycle sewage on the ground, a carpet or a table top to the water storage barrel. For example, the cleaning device shown in fig. 12a comprises a body 9, a cleaning device 3, and a self-watering device (not shown in fig. 12 a). Wherein the body 9 is provided with a water storage tub 1 and a vacuum source (not shown in fig. 12 a) for generating a suction force. The cleaning device 3 is arranged on the machine body 9, and under the action of the suction force, sewage generated when the cleaning device 3 executes a cleaning task is collected into the water storage barrel 1. Referring to the structure provided in any one of fig. 1 to 11b, the self-pumping device 2 has the capability of automatically pumping water and purifying water. At least part of the water self-drawing device 2 is arranged in the water storage barrel 1, and actively draws and purifies the water in the water storage barrel 1 and discharges the water from the water outlet end of the water self-drawing device 2, so that the water self-drawing device can be used when the cleaning device performs a cleaning task.

The specific implementation structure of the self-pumping device 2 and the manner of disposing the self-pumping device 2 on the water storage tank 1 can refer to the contents of the above embodiments and the illustrations shown in fig. 1 to 11b, which are not described herein again.

Fig. 12a shows an implementation scheme that only one water storage bucket 1 is arranged on the cleaning device, and the water storage bucket 1 is used for recovering sewage generated by cleaning of the cleaning device 3. The water self-sucking device in the water storage barrel 1 sucks water, and water discharged from the water outlet end of the water self-sucking device can be directly sprayed to cleaning surfaces such as the ground, a carpet, a table top and the like or a cleaning device (such as a cleaning head or a cleaning cloth). Specifically, the water outlet end of the water self-sucking device is communicated with the water spraying port through a water spraying pipeline so as to spray the water discharged by the water self-sucking device to the cleaning device or the cleaning surface.

Figures 13, 14 and 15 show another embodiment in which two tanks are provided on the cleaning device. Wherein, the water storage barrel 1 mentioned above is a sewage barrel; the machine body 9 is also provided with a clear water barrel 10. Water discharged from the water outlet end of the self-water drawing device can enter the clear water barrel 10; the clean water tub 10 communicates with a water spray opening to spray water in the clean water tub 10 to the cleaning device 3 or the floor through the water spray opening.

Further, one end of the machine body 9 can be rotatably connected with the cleaning device 3; namely, the other end of the machine body 9 is provided with a handle 91; the clean water barrel 10 and the sewage barrel (i.e., the water storage barrel 1) are located between the cleaning device 3 and the handle 91. More specifically, as shown in fig. 13, the slop pail is close to the cleaning device 3, and the clear pail 10 is close to the handle 91. Stated differently, when the cleaning device is in the working state, the cleaning device is in the upright state as shown in fig. 13, and the slop pail is located below the clean water pail 10. Still alternatively, as shown in fig. 14, the clean water tank 10 is located below the dirty water tank. As also shown in fig. 15, the slop bucket and the clean water bucket 10 are stacked in a direction perpendicular to the machine body. Fig. 15 shows a case where the slop pail is stacked above the clear water pail, and in fact, the clear water pail may also be stacked above the slop pail, which is not limited in this embodiment.

Further, the cleaning device 3 includes a base and a cleaning head. Wherein both the base and the cleaning head are not shown in the figures. The shape, structure, and the like of the base are not limited in this embodiment. The cleaning head may include, but is not limited to, at least one of the following: rolling brushes, rags, etc. The base can move on the surface to be cleaned and can rotate relative to the machine body. The cleaning head is arranged on the base, and the cleaning head is in contact with the surface to be cleaned to perform cleaning work. The base is provided with a suction port which is communicated with the water storage barrel through a suction pipeline, and the suction pipeline is internally provided with the suction force; under the action of the suction force, sewage generated when the cleaning head performs cleaning work enters the suction pipeline from the suction port into the water storage barrel.

The clear water barrel of the cleaning device can be connected with the input end of the liquid supply pump through an internal pipeline, and the output end of the liquid supply pump is communicated with the spray opening of the cleaning head through a hose and an outer pipe on the machine body. The handle can be provided with a handle with a holding through hole in the middle part, so that the holding operation is convenient. The suction port of the cleaning head enters a sewage bucket in the self-drawing water recycling system through a pipeline. The vacuum source can be arranged on the base or the machine body and used for generating vacuum airflow, and the vacuum source is connected with an air outlet on the self-drawing water recycling system.

The self-drawing water recycling system provided by the embodiment of the application is used for various types of equipment with liquid recovery, such as cleaning vehicles, handheld cleaning equipment, vertical cleaning equipment, cleaning robots and the like used indoors and outdoors, such as business supermarkets, hotels, squares and the like.

The following describes the scheme provided in this embodiment with reference to a specific application scenario. The cleaning device in this scenario is a vertical washer with a water storage tank as shown in fig. 12 a. The user holds the handle to push the cleaning machine to clean the ground. The user can press the water spray control on the handle to control the cleaning machine to spray water to the ground or the cleaning head from the water storage bucket. After a user presses the water spraying control on the handle, the self-water-drawing device in the water storage barrel automatically draws and purifies water in the water storage barrel and sprays the water to the ground or the cleaning head. The cleaning head is provided with a suction port, and sewage generated by cleaning the cleaning head on the ground enters the water storage barrel through a suction pipeline through the suction port. The liquid in the water storage barrel is recycled, the frequency of water replenishing or pouring of the water storage barrel is reduced, and the effects of water conservation and environmental protection are achieved.

In another scenario, a self-watering device floats within a water storage tank of the cleaning apparatus. The cleaning device may be an upright cleaning device as shown in figure 12a, the water storage tank 1 being arranged on the upright of the upright cleaning device. When a user holds the handle and cleans the ground by using the cleaning device, the user cleans the ground to the position of the table by using the cleaning device, and a gap below the table needs to be cleaned. The user holds the handle and rotates so that the pole setting is rotatory relative cleaning device of cleaning device, and the contained angle grow of pole setting and cleaning device is convenient for cleaning device stretches into the gap and cleans. As shown in fig. 12b, the change in the posture of the vertical rod causes the change of the liquid in the water storage tank 1. The liquid level of the liquid in the water storage tank 1 is always horizontal. Since the self-watering device 2 floats in the water storage tub 1, after the water storage tub 1 is changed from the posture of fig. 12a to the posture of fig. 12b, the self-watering device 2 can always contact with the liquid in the water storage tub 1, and cannot be separated from the water surface, and the cleaning work of the cleaning apparatus is not affected. That is, compared with the scheme that the self-drawing water device is fixedly arranged at a certain position of the water storage barrel, the scheme has the characteristic of self-adaption, and no matter how a user inclines or shakes the cleaning equipment, the normal work of the self-drawing water recycling system is not influenced.

In yet another scenario, the cleaning device is a self-moving device, such as a washing robot as shown in fig. 16. The cleaning robot can automatically plan a cleaning route and execute cleaning work according to the cleaning route. The cleaning robot is provided with two barrels, one is a sewage barrel 11, and the other is a clear water barrel 10. The slop water tank 11 is provided with a self-pumping device (not shown in fig. 16) to actively pump the water in the slop water tank 11 and discharge the pumped water into the clean water tank 10 for recycling. Under the action of the self-water-drawing device, water is continuously supplied to the clean water bucket 10, and water is continuously discharged to the outside from the sewage bucket 11, so that the cleaning robot can clean a larger area after water is supplied and poured once, and the cleaning efficiency is improved. Alternatively, the autonomous mobile device is a robot dedicated to collecting water accumulated on the ground. The robot is provided with a water storage barrel, and a self-water drawing device is arranged in the water storage barrel. The user can control or the robot can autonomously control the self-pumping device to work, for example, after the accumulated water collection work is completed or the water storage tank is full, the self-pumping device can be controlled to work so as to purify the liquid in the water storage tank, and the discharged purified water can be used by other equipment or personnel.

In a further scenario, the cleaning device is a washing robot, which is provided with only the slop pail 11, without a further clear water pail 10. The sewage bucket 11 is provided with a self-water-drawing device to actively draw the water in the sewage bucket 11 and directly discharge the drawn water to the surface to be cleaned or the roller brush. The suction port of the cleaning robot sucks sewage into the sewage bucket, and under the action of the self-water-sucking device, the sewage bucket 11 continuously discharges water outwards for cyclic utilization. Cleaning machines people can wash bigger area like this after moisturizing once, has improved and has washd the effect, and cleaning machines people goes up only to set up a bucket, has saved a lot of structural design spaces to make cleaning machines people more miniaturized, perhaps can hold more other components under the unchangeable condition in cleaning machines people structure space.

When the self-drawing water recycling system provided by the embodiment is implemented, the self-drawing water device 2 is directly placed in the sewage, and substances in the sewage are easy to adhere to the outer surface of the self-drawing water device 2 to block the porous structure of the self-drawing water device 2, so that the water drawing effect of the self-drawing water device 2 is affected, and the water purifying effect by using the self-drawing water device 2 is reduced. Therefore, a layer of filtering structure may be disposed at the periphery of the water self-drawing device 2 to filter the sewage once and then draw water from the water self-drawing device 2. Of course, a multi-layer filtering structure may be disposed on the periphery of the water self-drawing device 2, which is not limited in this embodiment, and the specific implementation may be determined according to the actual design requirement. As shown in fig. 17a, the filtering means 7 is provided at the periphery of the water self-drawing means 2. As shown in fig. 18, 19 and 20, the filtering device 7 is disposed in the water storage barrel 1 and is used for filtering the liquid in the water storage barrel 1 at least once to obtain a filtrate. The self-water-drawing device 2 has the capability of automatically drawing and purifying water, and actively draws and purifies the water in the filtrate and discharges the water from the water outlet end of the self-water-drawing device 2 for the use of the cleaning equipment during working. Fig. 18 and 19 are views each showing the self-watering device 2 placed in the water storage tub 1 from above. Fig. 20 shows a configuration in which the self-watering device 2 is fixed to the wall 103 of the water storage tub 1. Fig. 20 is different from fig. 5 in that a filter 7 is additionally provided outside the self-watering device 2 in fig. 20. Fig. 20 differs from fig. 6 in that the filter unit 7 in fig. 20 is attached to the attachment 4 of the self-tapping device 2; in fig. 6, a fixing base 300 (provided with a filtering hole, which may also be used as a filtering device) is integrated with the tub wall 103 or connected to the tub wall 103.

Wherein, the filtering device 7 can be realized by adopting porous materials such as active carbon, filter cloth, PP cotton, pore plates and the like. The fixing base 300 shown in fig. 4a, 4b and 6 can be provided with suitable filtering holes, or can be implemented by using porous filtering materials such as activated carbon, filtering cloth, PP cotton, and pore plates, and can also be used as a filtering device. Big granule filtration in the water storage bucket sewage of filter equipment is filtered, draws moisture by the water absorption device again, can effectual improvement water absorption device's live time and life-span.

With reference to fig. 17a, 18, 19 and 20, the filter device 7 is a filter cartridge; the filtering sleeve is provided with a plurality of filtering holes or is made of porous materials such as active carbon, filter cloth, PP cotton, pore plates and the like. The filtering sleeve is positioned at the periphery of the self-water-drawing device 2. Wherein, the arrangement mode of the filtering sleeve comprises any one of the following modes:

the setting method is as follows:

the filtering sleeve is fixedly connected with the inner wall of the water storage barrel 1. In particular, the structure of the filter cartridge may be the same as or similar to the structure of the holder 300 shown in fig. 4a, 4b and 6. The fixing seat 300 is provided with a plurality of filtering holes or is made of porous materials such as active carbon, filter cloth, PP cotton, pore plates and the like, the function of the fixing seat is the same as that of the filtering sleeve, liquid in the water storage barrel 1 can be filtered at one time, and filtered liquid entering the filtering sleeve is further sucked by the self-water-drawing device.

The setting mode is two:

the filtering sleeve and the water storage barrel 1 are of an integral structure, and as shown in fig. 6, the filtering sleeve and the barrel wall 103 of the water storage barrel 1 are of an integral structure. As shown in fig. 19, the filtering sleeve and the bottom of the water storage barrel 1 are of an integral structure.

The setting mode is three:

with reference to the structure shown in fig. 17a, the connection member 4 is disposed at the water outlet end of the self-tapping device 2, and the filter sleeve (i.e., the filter device 7) is connected to the connection member 4. The connecting piece 4 has two opposite ends, one end is used for connecting the water outlet pipe 204, and the other end is provided with a clamping groove 401 for clamping the filtering sleeve (i.e. the filtering device 7). As shown in the enlarged view of fig. 17b, the second end of the connecting member 4 is provided with a locking groove 401, and one end of the filter sleeve (i.e. the filter device 7) is provided with a locking buckle 121. When assembling, the user can hold the filter cartridge by hand and insert the catch 121 into the slot 401 to mount the filter cartridge on the connector 4. When the user wants to disassemble, e.g. unpick and wash, the filter device 7 and the self-watering device 2, the user can hold the connecting element 4 with one hand and the filter cartridge with the other hand, and pull the filter cartridge out of the connecting element 4 with the two hands in two opposite directions along the cartridge axis of the filter cartridge. In the structure shown in fig. 19, in the case that the filter sleeve and the bottom of the water storage barrel 1 are an integral structure, the top of the filter sleeve may be provided with a buckle 121, and the connector is provided with a slot 401, so that a user can insert the self-watering device 2 into the filter sleeve, align the slot 401 with the buckle 121, and press down the connector 4, thereby completing the connection between the self-watering device 2 and the filter sleeve, and simultaneously fixing the self-watering device 2 in the water storage barrel 1.

The above-mentioned structure of at least one partition plate 8 is provided in the water storage barrel 1, as shown in fig. 11a and 11 b. The partition 8 can actually perform a certain filtering function. Specifically, the at least one partition 8 divides the water storage bucket 1 into at least two bucket areas 106; the height of the at least one partition plate 8 is lower than the height of the wall of the water storage barrel 1; the self-scooping device 2 is disposed in a partial barrel region of the at least two barrel regions 106. Specifically, the at least two barrel areas 106 include an upstream barrel area and a downstream barrel area, the self-pumping device 2 is disposed in the downstream barrel area, and the liquid in the upstream barrel area exceeding the partition 8 enters the downstream barrel area, so that the self-pumping device 2 actively pumps and purifies the liquid entering the downstream barrel area. Reference may be made in particular to fig. 11a, 11b and the description of said fig. 11a and 11b (see above). Fig. 21 shows a solution based on fig. 11a, in which a part of the at least one partition 8 is provided with filtering holes, so that the filtering efficiency can be improved. Alternatively, the partition 8 is made of porous material such as activated carbon, filter cloth, PP cotton, and orifice plate. After the partition plate 8 plays a role of primary filtration, the filtering device 7 (such as a filtering sleeve) arranged at the periphery of the self-water-drawing device 2 can be used for secondary filtration, and after the secondary filtration by the partition plate and the filtering device 7, the water is drawn by the self-water-drawing device.

Fig. 21 shows an example in which a partition 8 is provided in the water storage tub 1 to divide the water storage tub into two parts, i.e., a left tub area and a right tub area in the drawing. If left bucket district is the upper reaches bucket district, after sewage got into left bucket district, the large granule can receive the action of gravity and deposit, and sewage gets into right side bucket district after filtering through the filtration hole on the baffle 8 or because of the filtration material of baffle. The right bucket zone is the lateral downstream bucket zone relative to the left bucket zone. The liquid entering the right barrel area is filtered by the filter 7, and finally is absorbed by the self-water-absorbing device 2 and discharged through the water outlet end. In practical implementation, the precision of the previous stage of filtration may be lower than that of the next stage of filtration, for example, as shown in fig. 21, the precision of the partition 8 may be lower than that of the filtration device 7, so that in a progressive manner, the pressure of each stage of filtration device may be reduced, and the probability of the filtration device being blocked may be reduced.

Fig. 22 shows another implementation of a filter device. As shown in fig. 22, the filter device 7 includes: a closed section 122 and a hydrophobic dust-removing filter screen section 123. Wherein the closed section 122 surrounds the upper portion of the water self-drawing device 2. A hydrophobic dust-repelling screen section 123 surrounds the lower portion of the self-watering apparatus 2. The liquid in the water storage tank 1 is filtered by the hydrophobic dust-removing filter network segment 123 and then enters the filter device 7, and the self-water-drawing device 2 enclosed therein draws water from the filtrate entering the filter device 7. In practical applications, the structures of the filtering device 7 and the self-water-drawing device 2 shown in fig. 22, the closed section 122 and the hydrophobic dust-removing filter segment 123 are combined to obtain a structure with a hollow inner cavity. The top end of the closed section 122 may be connected to the connector 4. The self-pumping device 2 is positioned in the hollow cavity. Because the closed section 122 isolates the liquid, the liquid cannot enter the hollow inner cavity through the closed section, and the liquid in the water storage barrel 1 enters the hollow inner cavity through the hydrophobic dust-removing filter screen segment 123, so that the self-watering device 2 can conveniently suck water from the filtrate entering the hollow inner cavity.

In a specific implementation, the hydrophobic dust filter segment 123 may be a PET xu chemical layer filter segment. Considering the problem that the service life of the self-pumping device 2 is shortened due to the fact that ultrafine particles such as colloidal fine particles of flour, clay and the like are easy to adhere to the surface of the self-pumping device 2, the scheme seals the periphery of the upper part of the self-pumping device 2, only a part of water inlet channels are left, a circle of PET (polyethylene terephthalate) Asahi layer filter screen (namely, only the filter section 123 in the figure 22 is left for water inlet) is arranged on the lower part of the self-pumping device 2, the filter screen has the characteristics of dewatering and dust removing, the filtering precision is high, the filter screen is not easy to block, and the service life and service life of the filter element can be effectively prolonged.

Alternatively, the filter device 7 may not be designed as a closed section, i.e. the filter device is surrounded by a ring of the filter device which is a layer of the filter cloth. In this case, due to the hydrophobic and dust-shedding characteristics of the Asahi layer screen, if the filter unit 7 is not fully submerged, the chamber of the filter unit will preferentially draw air from the non-submerged portion rather than liquid from the submerged portion under the negative pressure. This will result in the filter device 7 having to be fully submerged in use for a smooth flow of liquid into the filter chamber and further into the self-tapping device 2.

As can be seen from the above, the filter device 7 adopts the design of combining the sealing section 122 and the asahi-grade layer filter screen section 123, and the filter device also has usability while preventing clogging by the asahi-grade layer filter screen section (i.e. most of the upper part of the filter device 7 is sealed, and only the lower part needs to be immersed in water when in use). For example, the structure design can realize the anti-blocking performance and the usability in a floating state.

As shown in fig. 23, a liquid inlet pipeline 6 for introducing liquid into the water storage barrel 1 is arranged at the bottom of the water storage barrel; the filtering device 7 is arranged at the position, which is lower than the pipeline opening 61, outside the pipeline opening 61 of the liquid inlet pipeline 6. The filtering device 7 divides the water storage barrel 1 into an upper layer and a lower layer; the self-water-drawing device 2 is positioned below the filtering device 7; after the liquid flowing out from the pipe port 61 passes through the filtering device 7, the filtered impurities are left on the upper layer of the water storage barrel 1, the filtered liquid enters the lower layer of the water storage barrel 1, and then the liquid on the lower layer of the water storage barrel 1 is filtered by the self-water-drawing device 2. Specifically, in the implementation shown in fig. 23, the filtering device 7 may be a filtering plate, and the filtering plate is provided with a first through hole, so that a pipeline connected to the water outlet end of the self-watering device 2 can extend out of the water storage barrel 1 through the through hole. The filter plate is also provided with a second through hole, the liquid inlet pipeline 6 penetrates through the second through hole, and sealing measures such as adding a sealing ring and the like can be taken at the second through hole. In the solution shown in fig. 24a and 24b, the filtering device 7 and the water self-drawing device 2 are of an integral structure.

Referring to the embodiment shown in fig. 9a and 9b, the water self-drawing device 2 has a ring structure; correspondingly, the filtering device 7 comprises an outer ring sleeve and an inner ring sleeve; the method comprises the following steps of; the outer ring sleeve is positioned outside the annular structure, and the inner ring sleeve is positioned inside the annular structure. In specific implementation, the outer ring sleeve, the inner ring sleeve and the self-water-sucking device positioned between the inner ring sleeve and the outer ring sleeve can be connected with the barrel cover 101 of the water storage barrel 1; or the tub cover 103 may be of an integral structure.

Fig. 10a and 10b provide a solution where a plurality of self-scooping devices are arranged around the water inlet line 6. The scheme is suitable for the water storage barrel with small diameter and high height. The liquid inlet pipeline 6 occupies a large volume in the water storage barrel, and the space around the liquid inlet pipeline 6 is narrow. A plurality of self-pumping devices 2 with smaller specifications (thin and long or thin and short) are connected in parallel, the number of the self-pumping devices 2 connected in parallel is selected according to the volume and flow requirements, the water outlet ends of the self-pumping devices 2 are combined into a path by a multi-way connecting structure, and a pressure source (such as a first pump) respectively provides pressure for the self-pumping devices 2 through a bus to work. In addition, the plurality of parallel self-pumping devices 2 can also have the advantage of increasing the flow rate, and can also avoid the problem that the single self-pumping device cannot work due to blockage, namely one or part of the self-pumping devices are blocked, and the rest of the self-pumping devices can work. In substance, in the solution shown in figures 10a and 10b, a filtering device 7 can also be provided. Namely, the filtering device 7 (such as the filtering sleeve is positioned at the periphery of the self-water-drawing device) and the self-water-drawing device 2 form a multi-stage filtering structure. A plurality of the multi-stage filtering structures are arranged around the periphery of the liquid inlet pipeline 6, for example, six multi-stage filtering structures are evenly distributed on the periphery of the liquid inlet pipeline 6 along the circumferential direction of the liquid inlet pipeline as shown in fig. 10a and 10 b. Or the multistage filtering structure is ring-shaped, as shown in fig. 9a and 9b, the filtering device 7 includes a ring-shaped filtering sleeve (i.e. the outer ring sleeve and the inner ring sleeve above), the self-pumping device 2 is ring-shaped, and the ring-shaped filtering sleeve is sleeved on the self-pumping device 2 of the ring-shaped structure, so as to obtain the ring-shaped multistage filtering structure; the annular multi-stage filtering structure surrounds the periphery of the liquid inlet pipeline.

The above-mentioned cleaning apparatus may also include the self-pumping water recycling system provided in this embodiment and having a filtering device added thereto. I.e. the cleaning device as provided in fig. 12a, 13, 14, 15 and 16, further comprises a filter means. Specifically, the cleaning apparatus includes:

the cleaning device is arranged on the machine body, and under the action of the suction force, sewage generated by the cleaning device executing a cleaning task is collected into the water storage barrel;

the self-water-drawing device is hydrophilic and has the capability of automatically drawing water;

the filtering device is arranged in the water storage barrel and is used for filtering the liquid in the water storage barrel at least once;

the self-water-drawing device is at least partially arranged in the water storage barrel, actively draws water in the liquid filtered by the filtering device and discharges the water from the water outlet end of the self-water-drawing device, so that the water can be used when the cleaning device performs a cleaning task. The structure and material of the filtering device, the position relationship between the filtering device and the water storage barrel and the self-watering device, etc. can be referred to the above, and are not described herein.

It is mentioned above that when the self-pumping device is placed in the sewage for a long time, substances in the sewage are easy to adhere to the outer surface of the self-pumping device to block the porous structure of the self-pumping device, thereby affecting the water pumping effect of the self-pumping device and reducing the water purification efficiency by using the self-pumping device. Therefore, a layer of filtering structure is arranged on the periphery of the self-water-drawing device to filter the sewage once and draw water by the self-water-drawing device. Although the structure protects the self-sucking water device from being blocked, the filtering device has the problems, and substances can be adhered to the filtering device to influence the filtering effect. Therefore, in addition to the above embodiments, a function of cleaning the self-watering device may be added.

Figures 25 to 32 show various self-watering device cleaning schemes. Referring to fig. 25 to 32, a self-drawn water recycling system includes: a water storage barrel 1, a self-water-drawing device 2, a cleaning component 20 and a control device 30. The self-water-drawing device 2 has the capability of drawing water and purifying water automatically, wherein at least part of the self-water-drawing device 2 is arranged in the water storage barrel 1, and when the cleaning equipment is in a working mode, water in the water storage barrel 1 is drawn and purified actively and is discharged from a water outlet end of the self-water-drawing device, so that the cleaning equipment can be used during working. A control device 30 for controlling the washing part 20 to work to wash the self-watering device 2 when the cleaning apparatus is in a self-cleaning mode.

In this embodiment, the filtering device 7 may be disposed on the periphery of the self-scooping device 2, and the content of the filtering device 7 can be referred to the corresponding content above.

In an implementation solution, the water storage tank 1 in the above-mentioned self-drawing water recycling system can be a sewage tank, and correspondingly, the self-drawing water recycling system also has a clear water tank 10. When the cleaning component 20 works, clean water is pumped from the clean water tank 10 to the sewage tank, so that the self-watering device 2 is cleaned by the clean water.

In specific implementation, the scheme of cleaning the self-drawing water device 2 by using the clean water in the clean water barrel 10 can be realized by adopting the following schemes:

the first scheme is as follows:

as shown in fig. 25, the cleaning part 20 includes a second pump 40; one end of the second pump 40 is communicated with the clear water barrel 10, and the other end is communicated with the water outlet end of the self-water-drawing device 2; the second pump 40 is used for pumping clean water from the clean water tank 10 to the water outlet end of the self-water-pumping device 2 when the cleaning device is in a self-cleaning mode, and entering the self-water-pumping device from the water outlet end so as to perform reverse cleaning on the self-water-pumping device. In the self-cleaning mode, the second pump 40 is activated under the control of the control device 30 to inject the clean water in the clean water tank 10 into the self-drawing device 2 from the water outlet end of the self-drawing device 2, and the clean water flows out from the self-drawing device 2, so that the impurities attached to the outer wall of the self-drawing device 2 can be washed away by the reverse water flow.

In an implementation, the second pump may be a water pump.

When the cleaning device is in the working mode, the second pump 40 is not operated, and at this time, the water actively drawn from the slop water tank (i.e. the water storage tank 1 in the figure) by the water drawing device 2 enters the cleaning device 3 through a pipeline from the water outlet end. Alternatively, as shown in fig. 25, the self-drawn water recycling system provided in this embodiment further includes a first pump 5. The first pump 5 is used for assisting the automatic water drawing and purifying amount of the self water drawing device 2. Specifically, one end of the first pump 5 is communicated with the clean water tank 10, and the other end is communicated with the water outlet end of the self-watering device 2, so as to pump the water filtered by the self-watering device 2 from the sewage tank to the clean water tank 10 when the cleaning device is in the working mode. Since the first pump 5 and the second pump 40 exist in the self-drawn water recycling system, a pipeline needs to be arranged. As shown in fig. 25, the first three-way port 60 includes a first port, a second port, and a third port. The first interface is communicated with the clear water barrel 10, the second interface is connected with one end of the first pump 5, and the third interface is connected with one end of the second pump 40. The second three-way port 61 includes a fourth port, a fifth port and a sixth port, the fourth port is communicated with the water outlet end of the self-tapping device 2, the fifth port is connected with the other end of the first pump 5, and the sixth port is connected with the other end of the second pump 40.

The process of filtering and cleaning with two water pumps is as follows: when the cleaning device is in the working mode, the control device 30 controls the first pump 5 to work and the second pump 40 to not work. The first pump 5 is used for conveying liquid discharged by the self-water-drawing device (or the self-water-drawing device and the filtering device act together) in the sewage bucket into the clean water bucket 10, and the other water outlet of the clean water bucket 10 is communicated with the cleaning device 3 to supply water for the cleaning device 3 so as to clean the ground, the carpet or the table top. When the cleaning device is in the washing mode, the control means 30 controls the first pump 5 not to be operated and the second pump 40 to be operated. The clean water in the clean water tank 10 is pumped by the second pump 40 and is transferred to the self-watering device in the dirty water tank (i.e. the water storage tank 1 in the figure), and the clean water is discharged from the interior of the self-watering device, i.e. the self-watering device is cleaned by the reverse water flow, so that the self-watering device (or the self-watering device and the filtering device) can be cleaned more thoroughly from the interior.

In practical implementation, a check valve may be further disposed between the first pump 5 and the clean water barrel 10 or the slop water barrel, and a check valve may be further disposed between the second pump 40 and the clean water barrel 10 or the slop water barrel. Thus, when one of the first pump and the second pump is operated, the liquid is prevented from circulating from the other pump which is not operated, and the operation efficiency of the pump is reduced.

Scheme II:

as shown in fig. 26, the second pump 40 has a forward and reverse bidirectional mode. When the cleaning device is in the working mode, the second pump 40 works in the forward mode, and the second pump 40 pumps the water filtered by the self-watering device 2 from the sewage bucket to the clean water bucket 10; when the cleaning apparatus is in the self-cleaning mode, the second pump 40 works in a negative mode, and the second pump 40 pumps the clean water from the clean water tank 10 to the water outlet end of the self-watering device 2, so as to enter the self-watering device from the water outlet end, thereby performing reverse cleaning on the self-watering device.

Fig. 26 differs from fig. 25 in the type of the second pump, which in fig. 25 is a one-way pump, i.e. after the water circuit is connected, the second pump pumps water only from the clean water tank to the slop water tank. While the second pump in fig. 26 is a bi-directional pump, the direction of pumping water can be changed under the control of the control device 30.

Fig. 26 shows a configuration in which the liquid in clean water tank 10 is poured into self-watering device 2 to clean self-watering device 2 from the inside to the outside. On the basis, an external flushing mechanism can be added. Referring to fig. 27, the cleaning part 20 further includes a third pump 41. One end of the third pump 41 is communicated with the clean water barrel 10, the other end is connected with a spray pipe 42, and a nozzle of the spray pipe 42 faces to the outer wall of the self-water drawing device 2. The number of the spray pipes 42 may be plural, the plural spray pipes 42 may be uniformly distributed on the outer circumference of the water self-drawing device 2, and the nozzles of the spray pipes 42 face the upper portion of the water self-drawing device 2, so that the water flow sprayed from the nozzles flows down from the upper portion of the water self-drawing device 2, and the cleaning is more thorough. When the cleaning device is in the self-cleaning mode, the control device 30 controls the second pump 40 and the third pump 41 to work simultaneously, and the liquid pumped into the self-pumping device by the second pump 40 flows out from inside to outside to wash away impurities attached to or blocked on the self-pumping device 2. The liquid pumped by the third pump 41 from the clean water tank 10 is sprayed to the outer wall of the self-watering device 2 through the spray pipe 42 to wash away impurities and attached impurities, etc. flushed from the inside to the outside.

Or the second pump 40 in fig. 27 is a bidirectional adjustable pump, that is, when the cleaning device is in the operation mode, the control device 30 controls the second pump 40 to operate in the forward mode, the third pump 41 does not operate, and the second pump 40 in the forward mode assists the self-watering device to pump water from the sewage bucket and pump the pumped water into the clean water bucket 10. When the cleaning apparatus is in the self-cleaning mode, the control device 30 controls the second pump 40 to operate in the negative mode, and the third pump 41 operates simultaneously to clean the self-pumping device 2 from the inside to the outside and flush the self-pumping device 2 from the outside.

The above-mentioned solutions are to use the liquid in the clear water tank 10 to clean the self-watering device 2. The present embodiment also provides another solution for cleaning without the aid of liquid in the clear water tank 10. That is, the cleaning part 20 outputs power to drive the self-watering device 2 to move in the slop water bucket (i.e., the water storage bucket 1 in the figure). In a specific implementation, the power output by the cleaning component 20 may be a rotary power, a swing power, or the like. As shown in fig. 28, 29 and 30, the cleaning part 20 is a rotating device 43, and the rotating device 43 drives the water self-drawing device 2 to rotate in the slop pail; for another example, as shown in fig. 31, the cleaning component 20 is a swing device, and the swing device drives the water self-drawing device 2 to swing in the slop pail.

As shown in fig. 28 and 29, the rotating device 43 may be a motor outputting rotational power, and a speed reducing mechanism may be disposed between the output end of the motor and the water self-scooping device 2, and the water self-scooping device 2 may rotate in water under the driving of the rotational power. The motor can be arranged at the bottom of the sewage bucket, and a rotary power output shaft connected with the self-water-drawing device 2 can penetrate through the bottom of the bucket and extend into the bucket. When the cleaning device is in the self-cleaning mode, the control device 30 controls the motor to start so as to drive the self-water-drawing device 2 to rotate around the axis of the self-water-drawing device, and the self-water-drawing device and the sewage in the water storage barrel 1 move relatively to each other, so that stains attached to the self-water-drawing device 2 can be cleaned, and the cleaning effect is achieved. The power source of the rotating device may be an additional motor, or may be sequentially driven by a rolling brush motor of the cleaning device, which is not limited herein.

For the equipment with only the water storage barrel 1 and no clean water barrel 10, the self-pumping device 2 is suitable to be cleaned by adopting the scheme that the cleaning part 20 outputs power to drive the self-pumping device 2 to move in the water storage barrel 1. If the water storage barrel 1 (or the sewage barrel) and the clear water barrel 10 are arranged, the reverse cleaning can be started simultaneously during rotating cleaning, and a better cleaning effect can be achieved under the condition of double pipes. I.e. the washing unit 20 comprises, in addition to the rotating means, a second pump 40. When the cleaning device is in a self-cleaning mode, the control device 30 controls the second pump 40 and the rotating device 43 to work, the second pump 40 pumps liquid from the clean water tank 10 and injects the liquid from the water outlet end of the self-water-drawing device 2 into the self-water-drawing device 2, under the action of the water flow from inside to outside, impurities blocked or attached to the self-water-drawing device 2 are washed away, and meanwhile, the rotating device 43 drives the self-water-drawing device 2 to rotate in the liquid in the water storage tank 1, so that the impurities on the self-water-drawing device 2 are washed away.

Of course, the second pump 40 may be a bi-directionally adjustable pump, i.e. when the cleaning device is in the working mode, the control means 30 controls the second pump 40 to be in the forward mode and the rotating means 43 to be inactive; the second pump 40 assists the self-pumping device 2 to pump water from the water storage tank 1 (or the sewage tank) and to transfer the pumped water into the clean water tank 10. When the cleaning apparatus is in the self-cleaning mode, the control device 30 controls the second pump 40 to be in the negative mode, the rotating device 43 works, and the second pump 40 and the rotating device 43 are in double-pipe connection to clean the self-watering device 2.

In the embodiment shown in fig. 28, the second pump 40 is the first pump 5, and the first pump 5 is a one-way pump, and is operated only when the cleaning apparatus is in the operating mode, so as to assist the self-water-drawing device 2 in drawing water from the water storage tank 1 (or the sewage tank), purifying the water, and conveying the drawn water into the clean water tank 10. When the cleaning device is in the self-cleaning mode, the control device 30 can control the first pump 5 not to work and control the rotating device 43 to work.

In the example of fig. 29, a third pump 41 is added to the example of fig. 28. One end of the third pump 41 is communicated with the clean water tank 10, the other end is connected with a spray pipe 42, a nozzle of the spray pipe 42 faces the outer wall of the self-water-drawing device 2 and is used for leading out the clean water in the clean water tank 10 and spraying the clean water to the self-water-drawing device 2, and the self-water-drawing device 2 is cleaned by the clean water sprayed by the spray pipe 42 while rotating.

The rotating device 43 may be a motor, and may be configured as shown in fig. 30 to output the rotational power. As shown in fig. 30, the rotating device 43 includes: impeller 432 and impeller cavity 431. The impeller 432 has a rotation shaft connected to the self-watering device 2; the impeller 432 is disposed in the impeller cavity 431 and has an air inlet and an air outlet. An air inlet of the impeller cavity 431 is communicated with an air flow duct, and driving air flow in the air flow duct can be generated by a main motor of the cleaning equipment; under the action of the airflow in the airflow duct, the impeller 432 is driven to rotate, so as to drive the self-watering device 2 to rotate. I.e. when the cleaning apparatus is in the self-cleaning mode, said control means 30 controls the operation of said main motor, the air flow generated by the operation of said main motor is introduced into the impeller chamber 432, and the air flow introduction action can be performed by corresponding actuators in the cleaning apparatus, which actuators can be controlled by the control means 30. For example, when the cleaning apparatus is in a self-cleaning mode, the actuator acts to direct the flow of air generated by the main motor into the impeller chamber 432. When the cleaning device is in the working mode, the actuator is returned to cut off the air path of the air flow generated by the main motor into the impeller cavity 432. The specific implementation structure of the actuator is not specifically limited in this embodiment.

Further, as shown in fig. 31, the cleaning member 20 may be a swing mechanism 44. The swing mechanism 44 may be disposed in the water storage tank 1, for example, the swing mechanism 44 is fixed to an inner wall or an upper cover of the water storage tank 1. The swing mechanism 44 drives the water sucking device 2 to swing so that the water sucking device and the sewage in the water storage barrel 1 move relatively, and the dirt attached to the water sucking device 2 can be cleaned to achieve a cleaning effect. Specifically, as shown in fig. 31, the swing mechanism 44 has a swing arm, and an end of the swing arm may be hinged to the connecting member 4 of the water self-pumping device 2.

The cleaning scheme of the self-water-drawing device 2 can also utilize air flow for cleaning. For example, as shown in fig. 32, the cleaning member 20 is used to introduce an air flow into the water scooping device 2, and the water scooping device 2 is cleaned by ejecting the air flow from the water scooping device 2.

For example, as shown in fig. 32, the cleaning member 20 includes: the valve 45 is controlled. Wherein, one end of the control valve 45 is communicated with the atmosphere or connected with a gas generator, and the other end is communicated with the water outlet end of the self-pumping device 2; when the pressure inside the water storage tank 1 is negative, the control valve 45 is in an open state, and the gas introduced through the control valve 45 enters the self-watering device 2 due to the pressure difference, so that an airflow flowing from the inside to the outside of the self-watering device 2 is generated, and substances attached to the surface of the self-watering device 2 loosen or fall off under the action of the airflow.

The control valve 45 is opened and closed under the control of the control device 30. Specifically, when the cleaning apparatus is in the working mode, the control device 30 controls the control valve 45 to be in the closed state; when the cleaning device is in the self-cleaning mode, the control device 30 controls the control valve 45 to be in an open state for introducing external atmosphere or gas generator. For example, the control device 30 may control the control valve 45 to open and control the gas generator to generate a gas flow with a suitable pressure based on the pressure of the water storage tank 1, so as to generate a gas flow that can be pumped into the self-watering device from the water outlet end of the self-watering device.

If the first pump 5 for assisting the water pumping device 2 to pump water exists in the self-pumping water recycling system, the self-pumping water recycling system provided by this embodiment may further include a third three-way port 62. One end of the first pump 5 is communicated with the clear water barrel 10; the third three-way port 62 includes a seventh port, an eighth port and a ninth port, the seventh port is communicated with the other end of the first pump 5, the eighth port is communicated with the control valve 45, and the ninth port is communicated with the water outlet end of the self-pumping device 2. When the cleaning device is in an operating mode, the first pump 5 is operated to pump the water filtered by the self-watering device 2 from the water storage bucket 1 (or a sewage bucket) to the clean water bucket 10; when the cleaning device is in a self-cleaning mode, the first pump 5 stops working, the water storage barrel 1 is in a negative pressure environment, the control valve 45 is in an open state, and gas introduced through the control valve 45 enters the self-water drawing device 2 from the water outlet end through the eighth interface and the ninth interface. Because the pressure in the water storage barrel 1 is less than the atmospheric pressure when the cleaning equipment works, the pipeline between the self-water-drawing device 2 and the control valve 45 can generate airflow flowing into the water storage barrel 1 due to the air pressure difference, and the airflow is sprayed out from the interior of the self-water-drawing device 2, so that dirt attached to the surface of the self-water-drawing device 2 can be loosened and fall off, and then is taken away by water, and the cleaning effect is achieved.

The scheme for cleaning the self-water-drawing device by utilizing the output power, the gas and the like is suitable for the condition that the cleaning equipment only has one water storage barrel and is also suitable for the condition that the cleaning equipment contains two barrels (the water storage barrel is a sewage barrel and also contains another clear water barrel).

What needs to be added here is: in the above, the self-watering device 2 is driven to rotate or swing, and if a filtering device is disposed outside the self-watering device 2, the rotating device 43 or the swinging device 44 can drive the self-watering device 2 and the filtering device 2 to rotate together.

Similarly, the self-cleaning self-pumping recycling system can be arranged on cleaning equipment with various types, structures and forms. The cleaning device may be a cleaning vehicle for a large-scale place such as a business super, a hotel, etc., a small handheld cleaning machine suitable for a home or an office, a vertical cleaning machine, or a cleaning robot, etc., which is not particularly limited in this embodiment. Based on the self-drawing water recycling system with the cleaning component, the application also provides cleaning equipment. The cleaning device has the self-pumping water recycling system provided in the above embodiments, and reference may be made to the above contents for the contents of the self-pumping water recycling system, which are not described herein again.

In addition, the present application also provides a cleaning apparatus based on the structure shown in fig. 12a to 15, which further includes a cleaning component and a control device in addition to the embodiment shown in fig. 12a to 15. Specifically, the cleaning apparatus includes:

a body 9 on which a water storage barrel 1, a vacuum source (not shown) and a handle 91 are arranged, the vacuum source being used for generating a suction force;

the cleaning device 3 is arranged on the machine body 8, and sewage generated by the cleaning device 3 in a cleaning task is collected into the water storage barrel 1 under the action of the suction force;

the self-water-drawing device has the capability of drawing water and purifying water automatically, wherein at least part of the self-water-drawing device is arranged in the water storage barrel, and when the cleaning equipment is in a working mode, water in the water storage barrel is drawn and purified actively and is discharged from a water outlet end of the self-water-drawing device so as to be used when the cleaning equipment works;

cleaning the component;

and the control device is used for controlling the cleaning component to work when the cleaning equipment is in a self-cleaning mode so as to clean the self-water-drawing device.

Wherein the control device may be the same device as a master controller (e.g. CPU) of the cleaning apparatus. That is, the cleaning component is controlled by a master controller of the cleaning device, and the master controller can also control the start and stop of other components in the cleaning device, operation parameters, and the like, such as the start and stop of the vacuum source, the power of the vacuum source, the start and stop of the ground brush driving motor, the rotation speed of the ground brush, the water spraying amount control, and the like, which are not exemplified herein.

The technical solution provided in this embodiment is described below with reference to specific usage scenarios.

After the user uses the cleaning device (such as the cleaning device shown in fig. 12 a) for a period of time, the user may feel that the self-watering device and/or the filtering device need to be cleaned, or see that the cleaning indicator light on the cleaning device is on. The user can touch a control or a touch screen on the cleaning equipment body, or send a cleaning instruction to the cleaning equipment by using a mobile phone, a tablet personal computer or intelligent wearable equipment; and after the control device of the cleaning equipment receives the cleaning instruction, the cleaning part is controlled to work. As shown in fig. 25 and 26, the second pump of the cleaning component is operated to pump the clean water in the clean water tank to the water outlet end of the self-watering device, so as to enter the self-watering device from the water outlet end, and the clean water flows from the interior of the self-watering device to the exterior under the action of pressure, so that the impurities on the self-watering device and/or the filtering device can be washed off, and the function of reversely cleaning the self-watering device by the clean water in the clean water tank is realized. Or as shown in fig. 27, in addition to the clean water being injected into the self-water-drawing device by the second pump for cleaning, the clean water in the clean water tank is pumped out by the third pump and is sprayed to the outer wall of the self-water-drawing device through the spray pipe, and the cleaning effect is good because the double pipes are arranged. As shown in fig. 28 to 32, the cleaning component, such as the rotating device, the swinging device, etc., drives the self-pumping device to move in the water storage barrel, so as to wash the self-pumping device in the water storage barrel; on the basis, if the second pump is connected to fill the clean water into the self-watering device, the cleaning effect is better. Alternatively, the self-watering device may be cleaned by using a pressure difference, as shown in fig. 32. After the washing, the user can continue to use or take off the water storage bucket and pour out or change the remaining liquid of washing in the water storage bucket for the clear water. By thus automatically self-cleaning the self-watering device and/or the filter device, the user can extend the length of time during which the self-watering device and/or the filter device is manually disassembled. For example, the specification suggests that the self-watering device and/or the filter device may be unpicked and washed for one or two weeks, etc., which may improve the filtering effect of the self-watering device and/or the filter device, so that the cleaning apparatus may reach a better working state. After the scheme provided by the embodiment is adopted, the specification can suggest that the user can disassemble and wash the self-pumping device and/or the filtering device for a longer time (such as one month), and a self-cleaning program is triggered after each or a plurality of uses (namely, the cleaning component is started to work so as to clean the self-pumping device and/or the filtering device); or the cleaning machine automatically triggers the self-cleaning program according to a preset period or program. Or after the user uses the cleaning equipment to trigger the shutdown control each time, the cleaning machine automatically triggers the self-cleaning program to clean the self-water-drawing device and/or the filtering device. And after 3 or 5 minutes of self-cleaning, stopping cleaning the self-water-drawing device and/or the filtering device, and shutting down the cleaning equipment. Wherein, the self-cleaning time length can be freely set or is a factory set value.

The cleaning equipment can judge whether to output a cleaning prompt or not by detecting the flow rate and the like of the water outlet end of the self-water-drawing device; the prompt may be a light prompt, a voice prompt, a shake prompt, or the like.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, and not to limit the same; although the present application has been described in detail with reference to the foregoing embodiments, it should be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions in the embodiments of the present application.
