[0040] Please refer to the following: Figures 1 to 6The present invention proposes a liquid spraying structure 100, which is provided with a liquid inlet 110, a plurality of liquid spraying nozzles 120 and a flow guiding channel 130. The liquid inlet 110 is connected to a water source pipeline and the liquid outlet 110 is connected to the flow guiding channel 130. The liquid inlet 120 is connected to the flow guiding channel 130 and the liquid outlet 120 is used to spray cleaning liquid onto the cleaning component 300 of the cleaning robot 1000.

[0041] The spray structure 100 can have various shapes; it can be cylindrical, square, or other shapes, without specific limitations. The cleaning liquid sprayed by the spray structure 100 can be of various types; it can be water, disinfectant, or other liquids with cleaning effects, without specific limitations.

[0042] The inlet end of the liquid inlet 110 is connected to the water source pipeline, and the outlet end of the liquid inlet 110 is connected to the guide channel 130. The shape of the liquid inlet 110 can be various, including circular, square, or other shapes, without specific limitations. The water source can be cleaning fluid stored in the storage chamber formed by the spray structure 100, cleaning fluid stored in an external box, or cleaning fluid stored in other ways, without specific limitations.

[0043] There are many possible positions for the liquid inlet 110. The liquid inlet 110 can be located above the liquid spraying structure 100, below the liquid spraying structure 100, or on the side surface of the liquid spraying structure 100. No specific limitation is made here.

[0044] The inlet ends of multiple spray nozzles 120 are connected to the guide channel 130, and the outlet ends of multiple spray nozzles 120 are used to spray cleaning fluid onto the cleaning component 300 of the cleaning robot 1000. The shape of the spray nozzle 120 can be various, including circular, square, or other shapes, without any specific limitation.

[0045] Multiple spray nozzles 120 are arranged along the length of the spray structure 100. The amount of liquid sprayed per unit time at the outlet end of each spray nozzle 120 is equal. There are many ways to arrange the multiple spray nozzles 120 along the length of the spray structure 100. The multiple spray nozzles 120 can be arranged in a wave shape along the length of the spray structure 100, or they can be arranged in a straight line along the length of the spray structure 100. The multiple spray nozzles 120 can also be arranged in other shapes along the length of the spray structure 100. No specific limitation is made here.

[0046] The cross-sectional shape of the flow guide channel 130 can be various. It can be circular, square, or other shapes; no specific limitation is made here. The extension shape of the flow guide channel 130 can also be various. It can extend in a straight line, in a wavy shape, or in other shapes; no specific limitation is made here.

[0047] Both the outlet end of the inlet 110 and the inlet end of the spray nozzle 120 are connected to the guide channel 103. The positional relationship between the outlet end of the inlet 110 and the inlet end of the spray nozzle 120 within the guide channel 130 can vary. The outlet end of the inlet 110 can be positioned towards the inlet end of the spray nozzle 120, or it can be positioned away from the inlet end of the spray nozzle 120. No specific limitation is made here. Preferably, the outlet end of the inlet 110 is positioned towards the inlet end of the spray nozzle 120. This allows the cleaning fluid flowing out from the outlet end of the inlet 110 to have the maximum velocity in the direction towards the inlet end of the spray nozzle 120, which is beneficial for the spray nozzle 120 to spray out the cleaning fluid.

[0048] The spray structure 100 is also equipped with an adjustment structure, which is connected to the outlet end of the spray nozzle 120. The adjustment structure is used to adjust the orifice diameter of the spray nozzle 120. By controlling the orifice diameter of the spray nozzle 120, the amount of liquid sprayed per unit time at the outlet end of the spray nozzle 120 can be adjusted. When the cleaning liquid sprayed by the spray structure 100 has a good cleaning effect on the cleaning component 300, the orifice diameter of the spray nozzle 120 can be reduced by adjusting the structure to reduce the amount of cleaning liquid used per unit time and avoid waste. When the cleaning liquid sprayed by the spray structure 100 has a poor cleaning effect on the cleaning component 300, the orifice diameter of the spray nozzle 120 can be increased by adjusting the structure to increase the amount of cleaning liquid used per unit time and improve the cleaning effect.

[0049] The technical solution of the present invention ensures that the amount of liquid sprayed per unit time at the outlet end of each spray nozzle 120 is equal. With this configuration, the cleaning effect of the spray structure 100 on the cleaning parts 300 of the cleaning robot 1000 is consistent, thereby improving the cleaning efficiency of the spray structure 100 on the cleaning parts 300 of the cleaning robot 1000.

[0050] Please see Figure 2 In some embodiments of the present invention, the flow channel 130 extends along the length direction of the spray structure 100, the number of inlets 110 is one, the outlet end of the inlet 110 is connected to the middle part of the flow channel 130 along the length direction, and a plurality of spray nozzles 120 are arranged along the length direction of the flow channel 130. The aperture of the plurality of spray nozzles 120 is gradually increased from the middle part of the flow channel 130 to both ends. In this way, the aperture of the spray nozzle 120 closer to the outlet end of the inlet 110 is smaller than the aperture of the spray nozzle 120 farther from the outlet end of the inlet 110. By reasonably adjusting the aperture, the amount of sprayed liquid at the outlet end of each spray nozzle 120 per unit time is equivalent.

[0051] Please see Figures 3 to 4 In some embodiments of the present invention, the flow channel 130 extends along the length direction of the spray structure 100, and there are two inlets 110. The outlet end of each inlet 110 is connected to the corresponding end of the flow channel 130 along its length direction. A plurality of spray nozzles 120 are arranged along the length direction of the flow channel 130, and the orifice diameters of the plurality of spray nozzles 120 are equivalent. With this arrangement, the two ends of the flow channel 130 along its length direction are connected to the outlet ends of the two inlets 110, so that the hydraulic pressure at all points in the flow channel 130 is equivalent, thereby making the spray volume at the outlet end of each spray nozzle 120 equivalent per unit time.

[0052] Please see Figure 1 Multiple spray nozzles 120 are arranged in multiple rows. Each row of spray nozzles 120 extends along the length of the spray structure 100. The multiple rows of spray nozzles 120 are also spaced apart along the height of the spray structure 100. The spray nozzles 120 in adjacent rows are staggered in the length of the spray structure 100. This arrangement makes full use of the space in the height of the spray structure 100, and the two adjacent spray nozzles 120 do not affect each other in the length of the spray structure 100. This allows the cleaning liquid sprayed by the spray structure 100 to cover a larger area of ​​the cleaning component 300 of the cleaning robot 1000, thereby improving the cleaning efficiency of the spray structure 100.

[0053] Please refer to the following: Figures 5 to 7In some embodiments of the present invention, the plurality of spray nozzles 120 are arranged in multiple rows, each row of spray nozzles 120 extending along the length direction of the spray structure 100, and the multiple rows of spray nozzles 120 are also spaced apart along the height direction of the spray structure 100. There are multiple flow channels 130, each of which extends along the length direction of the spray structure 100 and is also spaced apart along the height direction of the spray structure 100. Each flow channel 130 is connected to the plurality of spray nozzles 120 in the corresponding row. There are multiple inlet ports 110, and the outlet end of each inlet port 110 is connected to the corresponding flow channel 130. With this arrangement, the plurality of spray nozzles 120 in each row are connected by the corresponding flow channel 130, so that the amount of sprayed liquid at the outlet end of the plurality of spray nozzles 120 in each row per unit time is not affected by the plurality of spray nozzles 120 in adjacent rows, thereby improving the spraying efficiency of the plurality of spray nozzles 120 in each row.

[0054] It should also be noted that when it is necessary to reduce the amount of cleaning fluid sprayed by the spray structure 100 onto the cleaning component 300 of the cleaning robot 1000, the flow channel 130 can be partially closed, so that the outlet ends of the multiple spray nozzles 120 corresponding to the closed flow channel 130 do not spray cleaning fluid, thereby reducing the amount of cleaning fluid sprayed by the spray structure 100 onto the cleaning component 300 of the cleaning robot 1000; when it is necessary to increase the amount of cleaning fluid sprayed by the spray structure 100 onto the cleaning component 300 of the cleaning robot 1000, the flow channel 130 can be partially opened, so that the outlet ends of the spray nozzles 120 corresponding to the opened flow channel 130 spray cleaning fluid, thereby increasing the amount of cleaning fluid sprayed by the spray structure 100 onto the cleaning component 300 of the cleaning robot 1000.

[0055] Furthermore, the flow channel 130 is connected to the liquid outlet of the inlet 110 at its middle section along its length, and the orifice diameter of each spray nozzle 120 connected to the flow channel 130 gradually increases from the middle section to both ends along the length of the flow channel 130; or, the flow channel 130 is connected to the liquid outlet of the inlet 110 at both ends along its length, and the orifice diameter of each spray nozzle 120 connected to the flow channel 130 is equivalent. With this configuration, the flow channel 130 is connected to the outlet end of the inlet 110 at its middle length. The orifice diameter of the spray nozzle 120 closer to the outlet end of the inlet 110 is smaller than that of the spray nozzle 120 farther from the outlet end of the inlet 110, thereby making the spray volume at the outlet end of each spray nozzle 120 equivalent per unit time. Alternatively, the flow channel 130 is connected to the outlet end of the inlet 110 at both ends of its length. The connection between the two ends of the flow channel 130 and the outlet ends of the two inlets 110 makes the hydraulic pressure at all points within the flow channel 130 equivalent, thereby making the spray volume at the outlet end of each spray nozzle 120 equivalent per unit time.

[0056] It should be noted that each flow channel 130 can be connected to the liquid outlet of the inlet 110 at its middle part along its length, and each flow channel 130 can be connected to the liquid outlet of the inlet 110 at both ends along its length. Each flow channel 130 can also be partially connected to the liquid outlet of the inlet 110 at its middle part along its length, and the other part can be connected to the liquid outlet of the inlet 110 at both ends along its length. No specific limitation is made here.

[0057] Please see Figure 4 In some embodiments of the present invention, the spray structure 100 includes a main body 140 and a cover 150. The main body 140 is recessed with a guide groove 141 on the side facing the cover 150. A plurality of spray nozzles 120 are formed through the bottom of the guide groove 141. The cover 150 is connected to the main body 140 and seals the opening of the guide groove 141. The cover 150 and the main body 140 together form a guide channel 130. A liquid inlet 110 is formed through the cover 150. This arrangement facilitates the formation of the spray structure 100 and improves the alignment accuracy of the guide channel 130 with each liquid inlet 110 and each spray nozzle 120.

[0058] It should be noted that there are many ways to connect the main body 140 and the cover 150. The main body 140 and the cover 150 can be connected by ultrasonic welding, screws, or other methods. No specific limitation is made here. Preferably, the main body 140 and the cover 150 are connected by ultrasonic welding, which ensures the airtightness of the main body 140 and the cover 150 and prevents the cleaning fluid from leaking from the gap between them. The main body 140 and the cover 150 can be made of the same material, or they can be made of different materials. No specific limitation is made here. The main body 140 and the cover 150 can be made of metal, or they can be made of a relatively hard plastic, or they can be made of other materials. No specific limitation is made here.

[0059] It should also be noted that if the bottom of the guide channel 141 is provided with an inlet 110 and the cover 150 is provided with a spray nozzle 120, the cleaning liquid flowing out of the inlet 110 will hit the cover 150 and then be diverted to the connection between the main body 140 and the cover 150. This will cause the connection between the main body 140 and the cover 150 to be impacted by the water flow, which may easily lead to the cleaning liquid leaking out from the connection between the main body 140 and the cover 150. However, if the bottom of the guide channel 141 is provided with a spray nozzle 120 and the cover 150 is provided with an inlet 110, the cleaning liquid flowing out of the inlet 110 will hit the bottom of the guide channel 141 and then be diverted to the wall of the guide channel 141, thereby avoiding the impact of the cleaning liquid on the connection between the main body 140 and the cover 150, and thus preventing the cleaning liquid from leaking out from the connection between the main body 140 and the cover 150.

[0060] To ensure that the spray structure 100 can stably spray cleaning fluid, the connection between the main body 140 and the cover 150 needs to have a certain degree of sealing to prevent the cleaning fluid from leaking from the gap between the main body 140 and the cover 150. Therefore, the spray structure 1000 also includes a sealing ring, which is installed at the opening of the guide groove 141. When the cover 150 closes the opening of the guide groove 141, the sealing ring abuts against the surface of the cover 150 facing the main body. With this arrangement, the gap between the main body 140 and the cover 150 can be sealed under the action of the sealing ring, preventing the cleaning fluid from leaking from the gap.

[0061] It should be noted that there are many kinds of materials used to form the sealing ring. The sealing ring can be made of nitrile rubber, EPDM, or other rubber materials. No specific limitation is made here.

[0062] Please see Figure 4In some embodiments of the present invention, the spray structure 100 includes a plurality of nozzles 160, the inlet end of each nozzle 160 being connected to the outlet end of the corresponding spray port 120. The outlet end of each nozzle 160 sprays cleaning liquid onto the cleaning component 300 of the cleaning robot 1000, and the shape of the cleaning liquid sprayed from each nozzle 160 is fan-shaped in the length direction of the spray structure 100. This arrangement increases the coverage of the cleaning liquid sprayed from each spray port 120 of the spray structure 100 onto the cleaning component 300 of the cleaning robot 1000, thereby improving the cleaning efficiency of the spray structure 100.

[0063] It should be noted that the nozzle 160 is only used to control the shape of the cleaning liquid sprayed from the spray nozzle 120, and does not affect the amount of liquid sprayed per unit time at the outlet end of the spray nozzle 120. The nozzle 160 can have many shapes; it can be a hollow cone, a solid cone, or directional. No specific limitations are made here. The nozzle 160 can be made of many materials; it can be made of metal, plastic, or ceramic. No specific limitations are made here.

[0064] Considering that the nozzle 160 needs to be set outwards, it is easy for dust to accumulate on the nozzle 160, causing it to become clogged. Therefore, the surface of the spray structure 100 facing the cleaning component 300 of the cleaning robot 1000 is provided with a protective groove 170. Multiple spray nozzles 120 are formed at the bottom of the protective groove 170. Multiple nozzles 160 are installed in the protective groove 170 and communicate with the corresponding spray nozzles 120. The distance between the end of the multiple nozzles 160 adjacent to the opening of the protective groove 170 and the bottom of the protective groove 170 is smaller than the distance between the bottom of the protective groove 170 and the opening of the protective groove 170. With this setting, the nozzle 160 has a protective groove 170 to block dust in the height direction of the spray structure 100, thereby avoiding dust accumulation on the nozzle 160 and causing it to become clogged.

[0065] Considering that the nozzle 160 needs to be positioned towards the cleaning component 300 of the cleaning robot 1000, the opening of the protective groove 170 also needs to be positioned towards the cleaning component 300 of the cleaning robot 1000. This makes it easy for dirt to accumulate at the bottom of the protective groove 170 during the operation of the cleaning component 300 of the cleaning robot 1000. Therefore, the bottom of the protective groove 170 between two adjacent nozzles 160 is provided with inclined surfaces that extend outward and intersect each other. The cleaning liquid sprayed by the nozzle 160 is at least partially sprayed onto the inclined surface to wash away the dirt adsorbed on the inclined surface.

[0066] This design allows dirt adhering to the inclined surface to be washed away, helping to keep the bottom of the protective tank 170 clean. It also reduces the likelihood of dirt accumulating on the bottom of the protective tank 170 after prolonged use and falling back onto the cleaning component 300 of the cleaning robot 1000, thus improving the cleaning effect of the water spray structure 100.

[0067] Please refer to the following: Figures 5 to 7 The present invention also proposes a cleaning robot 1000, which includes a machine body 200, a cleaning component 300, and a spray structure 100. The cleaning component 300 is installed at the bottom of the machine body 200, and the spray structure 100 is installed on the machine body 200. The spray nozzle 120 of the spray structure 100 is arranged facing the cleaning component 300. The specific structure of the spray structure 100 is as described in the above embodiments. Since the cleaning robot 1000 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0068] The machine body 200 also includes a housing, which is installed on the machine body 200 and is used to protect other structural components inside the machine body 200. Since the housing is located on the outside of the machine body 200 and is frequently bumped, the housing can be made of a harder material. The housing can be made of metal, hard plastic, or other materials, without specific limitations.

[0069] The machine body 200 also includes two walking modules and a control module. The two walking modules are installed in parallel at the bottom of the machine body 200 and are used to drive the shell movement. The control module is installed inside the shell and is connected to the two walking modules. It is used to control the two walking modules to move forward, backward, and turn on the ground.

[0070] The cleaning component 300 is installed on the machine body 200. There are many types of cleaning components 300; it can be a mop, a roller, or other objects used for cleaning floors. No specific limitations are made here. The cleaning component 300 can be installed on the machine body 200 in various ways, including by snap-fitting or by screw connection. No specific limitations are made here.

[0071] The cleaning robot 1000 also includes a baffle strip, which is installed at the bottom of the machine body 200 and located behind the cleaning component 300. The baffle strip extends along the length of the machine body 200 and is elastic. There is a certain gap between the baffle strip and the cleaning component 300. During the movement of the cleaning robot 1000, the baffle strip scrapes the surface to be cleaned to collect dirt on the surface to be cleaned. This design improves the cleaning effect of the cleaning robot 1000.

[0072] The spray structure 100 is installed on the machine body 200. The spray nozzle 120 of the spray structure 100 is oriented towards the cleaning component 300.

No specific limitation is made here.

Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
