Description

Technical Field

[0001] This utility model relates to the field of window cleaning machine technology, and in particular to a water spraying device for a window cleaning robot. Background Technology

[0002] Window cleaning robots are a type of smart home appliance. They can firmly adhere to glass using a vacuum pump or fan at their bottom, and then automatically detect the distance to the corners of the window and plan the cleaning path with the help of artificial intelligence. Window cleaning robots generally use the force of their adhesion to the glass to drive the cloth at the bottom of the machine to wipe away the dirt on the glass. In the current technology, window cleaning robots spray less water and have a narrower water coverage area, resulting in a longer cleaning time and affecting the cleaning efficiency of the window cleaning machine. Utility Model Content

[0003] To overcome the problems of insufficient water volume and narrow water coverage in window cleaning robots, resulting in long cleaning times and reduced cleaning efficiency, this utility model aims to provide a water spraying device for window cleaning robots. This utility model is achieved through the following technical solution:

[0004] A water spraying device for a window cleaning robot includes a support, on which a water spraying assembly capable of changing the spraying angle is mounted. The water spraying assembly includes a first water spraying structure, a second water spraying structure, and a third water spraying structure. By replacing one or more of the first, second, and third water spraying structures, the spraying angles between the first, second, and third water spraying structures and their individual spraying angles can be controlled, thereby enabling the water spraying assembly to expand the spraying range and increase the spraying volume.

[0005] As described above, the water spraying device of a window cleaning robot has an angle α between the first water spraying structure and the second water spraying structure. Adjusting the angle α increases the spraying area of ​​the first water spraying structure and the second water spraying structure.

[0006] As described above, in the water spraying device of a window cleaning robot, the angle between the second water spraying structure and the third water spraying structure is angle β. Adjusting angle β increases the spraying area of ​​the second and third water spraying structures.

[0007] As described above, in the water spraying device of a window cleaning robot, the angle between the first water spraying structure and the first direction is angle γ. By adjusting angle γ, the angle of water spraying by the first water spraying structure is changed, thereby changing the water spraying range of the first water spraying structure.

[0008] As described above, in the water spraying device of a window cleaning robot, the angle between the second water spraying structure and the first direction is angle δ. By adjusting angle δ, the angle of water spraying by the second water spraying structure is changed, thereby changing the water spraying range of the second water spraying structure.

[0009] As described above, in the water spraying device of a window cleaning robot, the angle between the third water spraying structure and the first direction is ε. By adjusting the angle ε, the angle of water sprayed by the third water spraying structure is changed, thereby changing the water spraying range of the third water spraying structure.

[0010] As described above, the water spraying device of a window cleaning robot includes a first spraying structure comprising a first nozzle for increasing water pressure to spray water flow, the first nozzle being connected to a first nozzle bracket for supporting the first nozzle, the first nozzle bracket being provided with a first nozzle mounting hole for mounting the first nozzle, a first spraying surface for spraying water flow in a predetermined area and a first connecting hole for connecting to a support being provided on the outer periphery of the first nozzle mounting hole.

[0011] As described above, the water spraying device of a window cleaning robot includes a second spraying structure comprising a second nozzle for increasing water pressure to spray water flow, the second nozzle being connected to a second nozzle bracket for supporting the second nozzle, the second nozzle bracket being provided with a second nozzle mounting hole for mounting the second nozzle, a second spraying surface being provided around the second nozzle mounting hole so that water flow is sprayed out in a predetermined area, and a second connecting hole for connecting to a support.

[0012] As described above, the water spraying device of a window cleaning robot includes a third spraying structure comprising a third nozzle for increasing water pressure and spraying water flow, the third nozzle being connected to a third nozzle bracket for supporting the third nozzle, the third nozzle bracket being provided with a third nozzle mounting hole for mounting the third nozzle, a third spraying surface for spraying water flow in a predetermined area and a third connecting hole for connecting to a support being provided on the outer periphery of the third nozzle mounting hole.

[0013] As described above, the water spraying device of a window cleaning robot includes a first mounting hole on the support for installing a first water spraying structure, a first support connecting hole on the outer periphery of the first mounting hole that mates with a first connecting hole, a second mounting hole on one side of the first mounting hole for installing a second water spraying structure, a second support connecting hole on the outer periphery of the second mounting hole that mates with a second connecting hole, a third mounting hole on one side of the second mounting hole for installing a third water spraying structure, and a third support connecting hole on the outer periphery of the third mounting hole that mates with a third connecting hole.

[0014] Compared with the prior art, the present invention has the following advantages:

[0015] 1. By changing the water spray assembly, the spray angles between the first, second, and third water spray structures, as well as their independent spray angles, can be controlled. This allows the water spray assembly to expand its spray range and increase the water volume, improving its flexibility and enabling it to complete cleaning work on a larger area in a shorter time. This increases work efficiency, improves the cleaning efficiency of the window cleaning machine, and reduces window cleaning time.

[0016] 2. By adjusting the angles between the first and second water spray structures, and between the second and third water spray structures, the horizontal spray range of the water spray components is expanded, thus accelerating the cleaning time of the window cleaning machine.

[0017] 3. By adjusting the angles γ, δ, and ε of the first, second, and third water spray structures, the water spray range in the first direction of the water spray assembly is expanded, thereby increasing the cleaning speed of the window cleaning machine. Attached Figure Description

[0030] To make the technical problems solved by this application, the technical solutions, and the beneficial effects clearer, this application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.

[0031] Please see Figure 1-11 A water spraying device for a window cleaning robot includes a support 2. A water spraying assembly 1 capable of changing the spray angle is mounted on the support 2. The water spraying assembly 1 includes a first spraying structure 11, a second spraying structure 12, and a third spraying structure 13. By replacing one or more of the first, second, and third spraying structures 11, 12, and 13, the spray angles between and independently of the first, second, and third spraying structures 13 can be controlled, allowing the water spraying assembly 1 to expand its spray range and increase the water volume. This improves the cleaning efficiency of the window cleaning robot, reduces cleaning time, and increases the spray range of the water spraying assembly 1 by changing the first, second, and third spraying structures 11 and 12. This enhances the flexibility of the water spraying assembly, allowing for flexible adjustment of the spray direction according to the specific conditions of the window, thus more accurately covering the area to be cleaned and effectively increasing the total spray coverage. This allows for cleaning a larger area in a shorter time, improving work efficiency. Users can replace different types of spraying structures according to actual needs to achieve the best cleaning effect.

[0032] Furthermore, as a preferred embodiment of this solution and not a limitation, the included angle between the first water spray structure 11 and the second water spray structure 12 is angle α, which expands the spray area of ​​the first water spray structure 11 and the second water spray structure 12. The included angle between the second water spray structure 12 and the third water spray structure 13 is angle β, which expands the spray area of ​​the second water spray structure 12 and the third water spray structure 13. The overall coverage of the water spray assembly can be expanded by angles α and β. Preferably, α is 25° and β is 25°. By replacing the first water spray structure 11, the second water spray structure 12 and the third water spray structure 13, the angle between the first water spray structure and the second water spray structure, and between the second water spray structure and the third water spray structure can be adjusted, expanding the spray range in the lateral direction of the water spray assembly and speeding up the cleaning time of the window cleaning machine. This design can significantly increase the lateral coverage area of ​​the water spray assembly, and a wider area can be cleaned in one operation, thereby reducing the number of times the window cleaning machine needs to be moved or adjusted.

[0033] Furthermore, as a preferred embodiment of this solution and not a limitation, the first water spray structure 11 is provided with an angle γ, which is the angle between the spray angle of the first water spray structure 11 and the first direction D. Adjusting the angle γ changes the spray angle, thereby changing the spray range of the first water spray structure 11. The second water spray structure 12 is provided with an angle δ, which is the angle between the spray angle of the second water spray structure 12 and the first direction D. Adjusting the angle δ changes the spray angle, thereby changing the spray range of the second water spray structure 12. The third water spray structure 13 is provided with an angle ε, which is the angle between the spray angle of the third water spray structure 13 and the first direction D. Adjusting the angle γ changes the spray angle, thereby changing the spray range of the third water spray structure 13. The angle ε changes the angle of the water spray, thereby changing the spray range of the third water spray structure 13. As a result, the overall spray range of the water spray assembly 1 can be changed and expanded. Preferably, γ is 55°, δ is 55°, and ε is 55°. By adjusting the angles γ, δ, and ε of the first, second, and third water spray structures, the spray range in the longitudinal direction of the water spray assembly is expanded, improving the cleaning speed of the window cleaning machine. By precisely controlling the relative angles between each water spray structure, the water flow can be better dispersed, avoiding local over-wetting while other areas are dry. This not only improves the cleaning effect but also helps to evenly wet the glass surface, facilitating the subsequent cleaning process.

[0034] Furthermore, as a preferred embodiment of this solution and not a limitation, the first spray structure 11 includes a first nozzle 111 for increasing water pressure and spraying water flow. The first nozzle 111 is connected to a first nozzle holder 112 for supporting the first nozzle 111. The first nozzle holder 112 is provided with a first nozzle mounting hole 1121 for mounting the first nozzle 111. A first spray surface 1122 for spraying water out in a predetermined area and a first connecting hole 1120 for connecting the support 2 are provided around the first nozzle mounting hole 1121. The first nozzle 111 effectively increases the water pressure. High-pressure water flow can more effectively remove stains and dust from the window surface. The first nozzle holder 112 provides stable support for the nozzle, ensuring its stability during operation. The first nozzle mounting hole 1121 allows the nozzle to be accurately positioned and fixed on the nozzle holder, which helps maintain consistency in the spray angle and direction, ensuring that the cleaning effect meets the expected standard each time it is used.

[0035] Furthermore, as a preferred embodiment of this solution and not a limitation, the second spray structure 12 includes a second nozzle 121 for increasing water pressure and spraying water. The second nozzle 121 is connected to a second nozzle holder 122 for supporting the second nozzle 121. The second nozzle holder 122 is provided with a second nozzle mounting hole 1221 for mounting the second nozzle 121. A second spray surface 1222 for spraying water in a predetermined area and a second connecting hole (1220) for connecting the support 2 are provided around the second nozzle mounting hole 1221. The second nozzle 121 effectively increases the water pressure. High-pressure water can more effectively remove stains and dust from the window surface. The second nozzle holder 122 provides stable support for the nozzle, ensuring its stability during operation. The second nozzle mounting hole 1221 allows the nozzle to be accurately positioned and fixed on the nozzle holder, which helps maintain consistency in the spray angle and direction, ensuring that the cleaning effect meets the expected standard each time it is used.

[0036] Furthermore, as a preferred embodiment of this solution and not a limitation, the third spray structure 13 includes a third nozzle 131 for increasing water pressure and spraying water. The third nozzle 131 is connected to a third nozzle holder 132 for supporting the third nozzle 131. The third nozzle holder 132 is provided with a third nozzle mounting hole 1321 for mounting the third nozzle 131. A third spray surface 1322 is provided around the third nozzle mounting hole 1321 to allow water to be sprayed out in a predetermined area, and a third connecting hole 1320 for connecting to the support 2. The third nozzle 131 effectively increases the water pressure. High-pressure water can more effectively remove stains and dust from the window surface. The third nozzle holder 132 provides stable support for the nozzle, ensuring its stability during operation. The third nozzle mounting hole 1321 allows the nozzle to be accurately positioned and fixed on the nozzle holder, which helps maintain consistency in the spray angle and direction, ensuring that the cleaning effect meets the expected standard each time it is used.

[0037] Furthermore, as a preferred embodiment of this solution and not a limitation, the support 2 is provided with a first mounting hole 21 for installing the first water spray structure 11. The outer periphery of the first mounting hole 21 is provided with a first support connecting hole 210 that mates with the first connecting hole 1120. One side of the first mounting hole 21 is provided with a second mounting hole 22 for installing the second water spray structure 12. The outer periphery of the second mounting hole 22 is provided with a second support connecting hole 220 that mates with the second connecting hole 1220. One side of the second mounting hole 22 is provided with a third mounting hole 23 for installing the third water spray structure 13. The outer periphery of the third mounting hole 23 is provided with a third connecting hole. The third support connection hole 230 of 1320 is used for connection. The first water spray structure can be replaced on the support by connecting the first connection hole to the first support connection hole. The second water spray structure can be replaced on the support by connecting the second connection hole to the second support connection hole. The third water spray structure can be replaced on the support by connecting the third connection hole to the third support connection hole. Each water spray structure can be installed independently in its own mounting hole, so that the three water spray structures form an optimal spatial relationship, which helps to expand the spray range and improve the uniformity of water flow distribution.

[0038] The working principle of this embodiment is as follows:

[0039] A water spraying device for a window cleaning robot is disclosed. The water spraying assembly can be prefabricated with a first water spraying structure at multiple angles γ, a second water spraying structure at multiple angles δ, and a second water spraying structure at multiple angles ε. Appropriate γ, δ, and ε can be selected and combined according to work requirements. Alternatively, a first and second water spraying structure at multiple angles α, and a third and second water spraying structure at multiple angles β can be prefabricated and combined to meet work requirements. The first, second, and third water spraying structures in the water spraying assembly can increase the water spray volume, change the water spraying range, and expand the water spraying area, thereby improving the cleaning efficiency of the window cleaning robot and reducing the window cleaning time. By adjusting the angles between the first and second water spraying structures, and between the second and third water spraying structures, the water spraying range in the lateral direction of the water spraying assembly can be expanded, accelerating the window cleaning time. By adjusting the first direction D angles γ, δ, and ε of the first, second, and third water spraying structures, the water spraying range in the first direction D of the water spraying assembly can be expanded, thereby increasing the cleaning speed of the window cleaning robot.
