The intelligent window cleaning robot is a novel robot represented by the intelligent window cleaning robot, and not only can help people to clean indoor glass, but also can complete outdoor high-altitude operation with high difficulty. When the intelligent window cleaning robot cleans, the intelligent window cleaning robot is adsorbed on a window by using a vacuum fan, continuously moves on glass through a travelling wheel, sprays cleaning liquid to a working surface, and then wipes and cleans the glass by using a rag arranged at the bottom of the window cleaning robot.

The existing window cleaning robot generally utilizes a spray head to spray atomized water drops and adsorb the atomized water drops on glass, and the water mist can effectively dissolve dust on the glass, so that the dust is more easily wiped and cleaned by a rag arranged at the bottom of the window cleaning robot, and the cleaning effect is improved.

Currently, two single-hole spray nozzles are commonly used for cross arrangement and combination of a window cleaning robot on the market to achieve the effect of increasing the water spraying coverage rate of the machine in the advancing direction, but the window cleaning robot can bring a plurality of problems, such as excessive parts, greatly increased production cost and increased damage possibility. Because two shower nozzles are needed, when two shower nozzles set up along vertical direction, the water in the pipeline between top shower nozzle and below shower nozzle can receive gravity influence whereabouts, in order to avoid the water whereabouts in the pipeline, still need set up the check valve in the pipeline between top shower nozzle and the liquid supply device to further improved the complexity of structure. And the spraying directions of the two single-hole spray heads are mutually crossed to influence the spraying distance, so that the collision of atomized water drops is increased, the water spraying uniformity is reduced, the water spraying blind area is large, the water spraying coverage rate is low, the uniformity is poor, the cleaning effect of the cleaning robot is also poor, and the use experience of a user is influenced.

The present disclosure provides a cleaning robot, which may be a cleaning robot for cleaning a floor, such as a floor sweeping robot, a floor mopping robot, a floor sweeping and mopping robot, or a cleaning robot for cleaning a window or a glass curtain wall, such as a window cleaning robot.

The cleaning robot at least comprises a machine body and a liquid spraying component, wherein the machine body is configured to move on a working surface, and a liquid supply device is arranged in the machine body; the liquid supply device is configured to supply cleaning liquid to the liquid spraying assembly, and the liquid spraying assembly is arranged at the edge position of the machine body and is configured to spray the cleaning liquid on the working surface. At least two nozzles are arranged on the liquid spraying assembly along the extending direction of the side wall of the machine body, the spraying axes of the nozzles are configured to radiate outwards on the outer side of the machine body in a mutually distant mode, and the spraying ranges of the adjacent nozzles are partially overlapped.

Like this, in the working process of this disclosed cleaning robot, the confession liquid device can be continuously to the liquid spray subassembly provides the cleaning solution, and the liquid spray subassembly can be through setting up two at least spouts along the extending direction of organism lateral wall and spray the cleaning solution on the working face.

For ease of understanding, the specific structure of the cleaning robot of the present disclosure and its operation principle will be described in detail with reference to fig. 1 to 10 in conjunction with one embodiment. It should be noted that, in order to keep the text concise, the disclosure further provides a liquid spraying assembly, and the liquid spraying assembly is described together when describing the cleaning robot, and will not be separately described.

As shown in fig. 1 and 2, the present disclosure provides a cleaning robot, which may be a cleaning robot for cleaning the floor, such as a floor sweeping robot, a floor mopping robot, a floor sweeping and mopping robot, or a cleaning robot for cleaning a window or a glass curtain wall, such as a window cleaning robot.

The cleaning robot at least comprises a machine body 200 and a liquid spraying assembly 100, wherein the machine body 200 is configured to move on a working surface, and a liquid supply device is arranged in the machine body 200 and is configured to supply cleaning liquid to the liquid spraying assembly 100. Specifically, the travelling wheels can be arranged on the machine body 200, and not only can the travelling wheels drive the cleaning robot to translate on the working surface, but also can drive the cleaning robot to turn on the working surface, so that the cleaning robot can move to all parts of the working surface, and then the whole working surface is cleaned. It will be appreciated that the cleaning robot is also provided with a cleaning assembly in the form of a dishcloth tray or the like for cleaning the work surface. When the cleaning robot is a window cleaning robot, a vacuum assembly may be further provided on the body 200, and the vacuum assembly adsorbs the window cleaning robot to a window by forming a negative pressure.

As shown in fig. 3, the spray assembly 100 is disposed at an edge position of the body 200 and is configured to spray the cleaning liquid onto the working surface. Specifically, taking the direction in fig. 1 as an example, the two sides of the machine body 200 are respectively provided with the liquid spraying assemblies 100, when the cleaning robot moves to the left in fig. 1, the liquid spraying assemblies 100 on the left can spray the cleaning liquid onto the working surface, when the cleaning robot moves to the right in fig. 1, the liquid spraying assemblies 100 on the right can spray the cleaning liquid onto the working surface, so that after the liquid spraying assemblies 100 spray the cleaning liquid onto the working surface to wet the working surface, the cleaning assemblies can clean the part of the working surface, and therefore dirt on the working surface is removed.

It will be appreciated that, as shown in fig. 4 and 5, both ends of the spray assembly 100 are provided with mounting holes 7, so that the spray assembly 100 can be fixed to the body 200 by a structure such as a bolt. Of course, in another embodiment of the present disclosure, other manners of fixing the spray assembly 100 may be adopted, and will not be described herein.

Wherein, as shown in fig. 4 and 5, at least two spouts 21 are provided on the spray assembly 100 along the extending direction of the side wall of the body 200, the spraying axes of the spouts 21 are configured to radiate outwardly away from each other outside the body 200, and the spraying ranges of the adjacent spouts 21 partially overlap.

Thus, in the operation of the cleaning robot of the present disclosure, the liquid supply device can continuously supply the cleaning liquid to the liquid spray assembly 100, and the liquid spray assembly 100 can spray the cleaning liquid onto the working surface by providing at least two spray nozzles 21 along the extending direction of the sidewall of the body 200.

Because the spraying axes of the spraying nozzles 21 radiate outwards in a mutually-far-away mode outside the machine body 200, the situation that the cleaning liquid mist sprayed by the spraying nozzles 21 is not mutually crossed and disturbed can be avoided, so that the spraying distance of the cleaning liquid flow can be effectively prolonged, the spraying blind area is reduced, and the cleaning liquid amount at the edge of the spraying range of the adjacent spraying nozzle 21 is basically consistent with the cleaning liquid amount at the center of the spraying range of each spraying nozzle 21 because the spraying ranges of the adjacent spraying nozzle 21 are partially overlapped, so that the coverage uniformity of the cleaning liquid mist sprayed by the spraying nozzle assembly 100 on the working surface is improved, the cleaning effect of the cleaning robot is further improved, and the use experience of a user is improved.

Moreover, the cleaning robot disclosed by the invention only adopts one liquid spraying component 100 to realize the liquid spraying function, so that the existing multiple spray heads can be integrated into a whole, the liquid supply device can be effectively communicated with the single liquid supply component, the number of connecting pipes between the spray heads is reduced, and the connecting pipes between the spray heads are not needed, so that a one-way valve is not needed, the whole structure is simpler, and the situation that water drops in a liquid supply pipeline fall to the ground after the cleaning robot stops can not be generated.

As shown in fig. 2 and 3, in one embodiment of the present disclosure, the liquid spray assembly 100 is provided at an edge position of the cleaning robot in a traveling direction thereof, and is configured to spray the cleaning liquid at least to the outside of the traveling direction of the cleaning robot; the cleaning robot's orthographic projection in its traveling direction is within the entire spray range of the spray assembly 100. Because the spray assembly 100 is disposed at the edge position of the cleaning robot in the traveling direction thereof, and sprays the cleaning liquid at least to the outer side of the traveling direction of the cleaning robot, the spray assembly 100 can be disposed at the edge position of the cleaning robot in the traveling direction thereof before the cleaning robot cleans, and sprays the cleaning liquid at least to the outer side of the traveling direction of the cleaning robot, so that the spray assembly 100 can wet the working surface before the cleaning robot cleans the working surface, and after the spray assembly 100 sprays the cleaning liquid to wet the working surface, the cleaning assembly can clean the working surface, thereby removing the dirt on the working surface. Since the orthographic projection of the cleaning robot in the traveling direction thereof is within the entire spray range of the spray assembly 100, it is ensured that the spray assembly 100 can wet all positions of the cleaning robot in the traveling direction thereof, avoiding omission.

In one embodiment of the present disclosure, the cleaning robot is configured to travel in a first direction, the spray assembly 100 is disposed at an edge position of the cleaning robot in the first direction thereof, and is configured to spray the cleaning liquid to the first direction when the cleaning robot travels in the first direction; and/or the cleaning robot is configured to travel in a second direction, the spray assembly 100 is disposed at an edge position of the cleaning robot in its second direction, and is configured to spray the cleaning liquid to the second direction when the cleaning robot travels in the second direction.

That is, taking the direction of fig. 1 as an example, when the body 200 moves only to the left in fig. 1, the spray assembly 100 may be disposed only at the left side of the body 200, that is, taking the direction of fig. 1 as an example, when the body 200 moves only to the right in fig. 1, the spray assembly 100 may be disposed only at the right side of the body 200, and when the body 200 may move to the left and right sides in fig. 1, the spray assembly 100 may be disposed at both the left and right sides of the body 200.

Of course, when the machine body 200 moves only to the left or right in fig. 1, the spray assemblies 100 may be disposed on both the left and right sides of the machine body 200, so that after the spray assemblies 100 located at the front side of the traveling direction of the cleaning robot spray the cleaning liquid onto the working surface to wet the working surface, the spray assemblies 100 located at the rear side of the traveling direction of the cleaning robot can continue to spray the cleaning liquid onto the working surface after the cleaning assemblies remove the dirt on the working surface, thereby facilitating the next cleaning to improve the cleaning effect.

As shown in fig. 1, in an embodiment of the present disclosure, in a cross section of the cleaning robot, an included angle between the injection axes of the respective nozzles 21 ranges from 20 ° to 40 °, and when an included angle a between the injection axes of the respective nozzles 21 ranges from 20 ° to 40 °, it is ensured that the included angles between the injection axes of the respective nozzles 21 are relatively average, and the overlapping ranges of the injection ranges of the adjacent nozzles 21 are relatively reasonable. Specifically, in one embodiment of the present disclosure, three nozzles 21 are disposed on the spray assembly 100 along the extending direction of the side wall of the machine body 200, and the included angle between the spraying axes of the nozzles 21 is 30 °, so that the arrangement can ensure that the included angle between the spraying axes of the nozzles 21 is even, and the overlapping range of the spraying ranges of the adjacent nozzles 21 is reasonable.

As shown in fig. 4, in one embodiment of the present disclosure, the diameter of the spout 21 is 0.2mm to 0.4mm. When the diameter of the nozzle 21 is 0.2mm to 0.4mm, each nozzle can cover a relatively proper spraying range, so that the range is not too small, too many nozzles 21 are required to be arranged, and the overlapping range of the spraying ranges of the nozzles 21 is too large. Specifically, in one embodiment of the present disclosure, the diameter of the spout 21 is 0.3mm. When the diameter of the nozzle 21 is 0.3mm, the spray range of each spray head is suitable.

As shown in fig. 2 and 3, in one embodiment of the present disclosure, the injection axis of each nozzle 21 is configured to be inclined toward the working surface outside the body 200, and the angle B between the injection axis of each nozzle 21 and the working surface ranges from 10 ° to 20 °. When the cleaning robot is a window cleaning robot, the spraying axes of the spraying nozzles 21 are inclined towards the direction of the working surface at the outer side of the machine body 200, and the included angle between the spraying axes and the working surface ranges from 10 degrees to 20 degrees, so that the proper amount of cleaning liquid flow sprayed onto the working surface by the liquid spraying assembly 100 can be ensured, the working surface cannot be wetted due to the fact that the cleaning liquid is not too small, and the cleaning liquid is accumulated to flow down along a window due to the fact that the cleaning liquid is too much.

Specifically, in one embodiment of the present disclosure, when three spray nozzles 21 are disposed on the spray assembly 100 along the extending direction of the side wall of the machine body 200, the included angle between the spray axes of the spray nozzles 21 located in the middle and the working surface is 17 °, and the included angle between the spray axes of the spray nozzles 21 located on both sides and the working surface is slightly smaller than 17 °. When the spraying axis of each spraying nozzle 21 is inclined towards the direction of the working surface at the outer side of the machine body 200, and the included angle between the spraying axis and the working surface is about 17 degrees, the cleaning liquid flow sprayed onto the working surface by the liquid spraying assembly 100 can be ensured to be more proper.

As shown in fig. 4 and 6, in one embodiment of the present disclosure, a spray assembly 100 includes a spray head base 10 with at least two spray orifices 21 disposed on the spray head base 10; at least two diversion trenches 3 are arranged in the nozzle base 10, and the at least two diversion trenches 3 are independent and jointly extend to a collecting area 4 corresponding to the position of the nozzle 21; the cleaning liquid is arranged to flow along the respective diversion trenches 3 to the collection area 4 and then to be ejected from the nozzle 21 after collision.

Like this, in the working process of hydrojet subassembly 100, the cleaning solution can flow to the collection district 4 that corresponds to spout 21 position along two piece at least independent guiding gutter 3 each other to flow to collect district 4 collision, produce a large amount of clean liquid drops that are vaporific and spout from spout 21 after, thereby effectively improved hydrojet subassembly 100's atomization effect, and then can improve the wetting effect of cleaning solution to the dirty on the working face, in order to improve cleaning robot's cleaning effect.

In order to supply the cleaning liquid into the respective diversion trenches 3, as shown in fig. 6 to 10, in one embodiment of the present disclosure, the nozzle mount 10 includes a nozzle cap 1 provided with a flow-through duct 5, and a nozzle 2 located on the nozzle cap 1; the spout 21 is provided on the nozzle 2, and the flow guide groove 3 is provided between the nozzle cover 1 and the nozzle 2, and is configured to communicate with the flow passage 5. Thus, during operation of the spray assembly 100 of the present disclosure, the cleaning liquid flowing out of the flow conduit 5 enters each of the flow guide grooves 3, flows into the collection area 4, collides therewith, and is sprayed out of the spray nozzle 21 after a large number of atomized cleaning liquid droplets are generated.

As shown in fig. 9 and 10, in one embodiment of the present disclosure, the nozzle cover 1 further includes a joint chamber 14, and each of the flow conduits 5 communicates with the joint chamber 14, respectively; spray assembly 100 also includes a nipple 6 connected to nipple cavity 14. Thus, during operation of the spray assembly 100 of the present disclosure, cleaning liquid flows from the inlet of the adapter 6 into the adapter cavity 14 and from the adapter cavity 14 into the corresponding flow channel 5 of each nozzle 2, so as to flow out of each nozzle 21 after impinging and atomizing within each nozzle 2.

As shown in fig. 9 and 10, in one embodiment of the present disclosure, since the pipe joint 6 has a land portion 61 located in the joint chamber 14 and extending toward the direction of the flow-through pipe 5. In this way, it can be ensured that too much cleaning liquid cannot be accumulated in the joint cavity 14, so that a large amount of liquid cannot drop from the joint cavity 14 under the influence of gravity after the liquid spraying assembly 100 is stopped, and the use experience of a user is effectively improved.

As shown in fig. 6, in one embodiment of the present disclosure, the size of the channel 3 at a location remote from the collection area 4 is greater than its size at a location adjacent to the collection area 4. The size of the diversion trench 3 far away from the position of the collection area 4 is larger than the size of the position of the diversion trench adjacent to the collection area 4, so that cleaning liquid can be gathered continuously in the process of flowing through the diversion trench 3, the flow speed of the cleaning liquid can be accelerated, the flow speed of the cleaning liquid sprayed out of the liquid spraying assembly 100 is improved, and the atomization effect of the liquid spraying assembly 100 can be improved.

Further, as shown in fig. 6, in one embodiment of the present disclosure, the extending direction of each of the diversion trenches 3 is configured to deviate from the center of the collection area 4 to the same side, so that each of the diversion trenches 3 is configured to be spirally distributed in the circumferential direction of the collection area 4. It will be appreciated that, since the extending directions of the respective diversion trenches 3 are deviated from the center of the collecting area 4 toward the same side, the respective diversion trenches 3 are configured to be spirally distributed in the circumferential direction of the collecting area 4, so that the respective cleaning liquid does not collide at the center of the collecting area 4 but at the edge of the collecting area 4 after flowing out of the diversion trenches 3, the collision range of the respective cleaning liquid can be expanded, and thus the water mist can be generated in the whole collecting area 4, not only at the center of the collecting area 4.

Further, as shown in fig. 6, in one embodiment of the present disclosure, the opening position of the flow guide groove 3 has a proximal end 31 and a distal end 32 flowing toward the collecting region 4, and the distal end 32 of the flow guide groove 3 is formed with an arc-shaped guide surface 33 curved toward the collecting region 4, and the cleaning liquid flowing out of the flow guide groove 3 is configured to flow into the collecting region 4 via the guide surface 33.

Because the arc-shaped guide surface 33 which is bent towards the collecting area 4 is formed at the position of the distal end 32 of the guide groove 3, the cleaning liquid flowing out of the guide groove 3 flows into the collecting area 4 through the guide surface 33, so that when the cleaning liquid flowing into the collecting area 4 from the guide surface collides with the cleaning liquid flowing in the adjacent guide groove 3, the included angle between the cleaning liquid flowing into the collecting area 4 and the cleaning liquid flowing into the adjacent guide groove is not an obtuse angle, but an acute angle slightly smaller than 90 degrees, thus the relative impact between the cleaning liquid and the cleaning liquid can be avoided, the flow speed of the cleaning liquid is reduced, the flow speed of the cleaning liquid can be effectively improved, the flow speed of the cleaning liquid sprayed out of the liquid spraying assembly 100 is improved, and the atomization effect of the liquid spraying assembly 100 can be improved.

As shown in fig. 10, in one embodiment of the present disclosure, the collecting area 4 is a truncated cone-shaped opening, so that the cleaning solution flowing out of each diversion trench 3 can be sprayed out of the nozzle 21 after the collecting area 4 collides and atomizes, so as to increase the flow velocity of the cleaning solution sprayed out of the nozzle 21. As shown in fig. 10, in one embodiment of the present disclosure, the nozzle 21 is opened in a truncated cone shape, so that the cleaning liquid ejected from the nozzle 21 can spread onto the working surface through the truncated cone-shaped opening, thereby expanding the ejection range of the cleaning liquid ejected from the nozzle 21.

As shown in fig. 7 and 8, in one embodiment of the present disclosure, the spray head cap 1 includes an inner cavity 11, and a post 12 extending outwardly from the bottom of the inner cavity 11 of the spray head cap 1; the surface of the cylinder 12 and the surface of the cavity 11 enclose an annular channel 13, and the nozzle 2 is configured to be mounted in the position of the annular channel 13; the flow guide groove 3 is configured to be formed between the nozzle 2 and the cylinder 12, and an end of the flow guide groove 3 remote from the collecting region 4 is configured to communicate with the annular passage 13. The surface of the cylinder 12 of the nozzle cover 1 and the surface of the inner cavity 11 form the annular channel 13, the nozzle 2 is arranged at the position of the annular channel 13, the nozzle 2 can be fixed by utilizing the structure of the nozzle cover 1, and the nozzle 2 is not required to be arranged by other structures, so that the number of required parts of the liquid spraying assembly 100 is reduced. And the guide grooves 3 are formed between the nozzle 2 and the column 12, and the end of the guide groove 3 remote from the collecting area 4 is communicated with the annular channel 13, so that the cleaning liquid can be supplied into each guide groove 3 by using the annular channel 13.

As shown in fig. 10, in one embodiment of the present disclosure, the end surface of the nozzle 2 is in contact with the end surface of the cylinder 12, and the diversion trench 3 and the collection area 4 are opened on the end surface of the nozzle 2. The end face of the nozzle 2 is contacted and matched with the end face of the cylinder 12, so that the diversion trench 3 and the collection area 4 are formed, the diversion trench 3 and the collection area 4 are not processed on a single structure, the processing difficulty of the diversion trench 3 and the collection area 4 can be effectively reduced, and the whole structure is simpler. In another embodiment of the present disclosure, the diversion trench 3 and the collection area 4 are arranged on the end face of the cylinder 12 of the nozzle 2, and the principle is similar, and will not be repeated here.

Specifically, as shown in fig. 6 and 10, in one embodiment of the present disclosure, the nozzle 2 has an outer wall 22 extending into the annular channel 13, and at least two flow passages 24, which are independent from each other and respectively communicate with the annular channel 13 and the corresponding diversion trench 3, are formed between the inner wall of the nozzle 2 and the outer surface of the column 12. As shown in fig. 6, at least two extrusion parts 23 having a cut-round shape are formed in the inner wall of the nozzle 2, and these extrusion parts 23 are in contact fit with the outer surface of the cylinder 12, so that at least two flow passages 24 which are independent from each other and respectively communicate with the annular passage 13 and the corresponding diversion trench 3 can be formed. Thus, during operation of the liquid spraying assembly 100 of the present disclosure, the cleaning liquid flowing into the annular channel 13 from the flow channel 5 is split into the flow channels 24 and then flows into the corresponding diversion trenches 3, so as to achieve the purpose of dispersing the liquid into the diversion trenches 3.

As shown in fig. 7 and 8, in one embodiment of the present disclosure, the flow conduit 5 is configured to deviate from the cylinder 12 and is configured to communicate with one side of the annular channel 13. Since the flow conduit 5 is offset from the column 12 and is configured to communicate with one side of the annular channel 13, the size of the flow conduit 5 can be effectively reduced to save the internal space of the spray assembly 100.
