[0002] As a product that can integrate functions of automatic floor sweeping, dust suction, and mopping, the cleaning robot has been widely used in domestic and commercial cleaning places due to its advantages such as high cleaning efficiency and good cleaning effect, effectively improving people's living environment by replacing manual labor. With the gradual increase of people's requirements, the intelligence of cleaning robots is also continuously improving, and a base station used in conjunction with the cleaning robot is derived to achieve functions such as automatic water replenishment. When the water in the cleaning water tank is exhausted, the cleaning robot can automatically return to the base station for water replenishment, and during the water replenishment process, it can automatically identify the water volume in the clean water tank and automatically stop water replenishment when the water is full.

[0003] However, the structure of the current water level recognition structure of the cleaning robot is still relatively complex, increasing the production cost of the cleaning robot while occupying the space of the fuselage, which is not conducive to the development of miniaturization of the cleaning robot. Summary of the Invention

[0004] In view of the problem that the structure of the water level recognition structure of the cleaning robot is relatively complex, this application provides a water supply module, a cleaning robot, and a cleaning robot system.

[0005] A cleaning device includes:

[0006] A cleaning component having a water inlet;

[0007] A clean water tank is provided above the cleaning component, and a water tank water outlet is provided at the bottom of the clean water tank close to the cleaning component;

[0008] A detection module is provided on one side of the top of the clean water tank away from the cleaning component.

[0011] In one embodiment, when the real-time water level in the detection channel reaches a preset water level, the detection unit sends a water full signal;

[0012] When the real-time water level in the detection channel is lower than the preset water level, the detection unit sends a water shortage signal.

[0015] In one embodiment, the channel wall of the detection channel has a reflect surface that extends in a zigzag manner. The detection unit is configured to emit detection light towards the reflect surface and receive the detection light reflected by the reflect surface.

[0016] In one embodiment, the reflect surface includes a first sub-reflect surface and a second sub-reflect surface arranged at an angle. The detection light emitted by the detection unit can return to the detection unit after being reflected by the first sub-reflect surface and the second sub-reflect surface in sequence.

The terms "vertical", "horizontal", "up", "down", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation.

[0047] An embodiment of this application provides a cleaning robot system (not shown in the figure), including a base station and a cleaning robot. The cleaning robot can move on the ground waiting to be cleaned to clean the ground, and the base station is used to dock with the cleaning robot to charge and replenish water for the cleaning robot.

[0048] As Figure 1As shown, the cleaning robot includes a main body (not shown in the figure) and a cleaning device 100, and the cleaning device 100 is installed in the main body. The cleaning robot has a cleaning mode and a water replenishment mode. When the cleaning robot is in the cleaning mode, the cleaning device 100 can use cleaning water to clean the surface to be cleaned. When the cleaning robot is in the water replenishment mode, the cleaning robot docks with the base station, and the base station replenishes cleaning water for the cleaning device 100.

[0049] As Figures 1 to 4 shown, the cleaning device 100 includes a cleaning assembly 10, a clean water tank 30, a detection module 50, a connecting pipe 70, and a water outlet pipeline 90.

[0050] The cleaning assembly 10 is used to clean the surface to be cleaned, and the cleaning assembly 10 has a water inlet 12a for water inlet. The clean water tank 30 is arranged above the cleaning assembly 10, and the cleaning water can be stored in the clean water tank 30. A water tank water outlet 30b for water outlet is arranged at the bottom of the clean water tank 30 close to the cleaning assembly 10. The detection module 50 is arranged on one side of the top of the clean water tank 30 far from the cleaning assembly 10. The detection module 50 includes a detection main body 52 and a detection unit 54 arranged on one side of the detection main body 52. The detection main body 52 has a detection channel 525, and the detection unit 54 is used to detect the real-time water level in the detection channel 525 and send a detection signal. One end of the connecting pipe 70 is connected to the water tank water outlet 30b, and the other end extends upward in a direction away from the cleaning assembly 10 to connect to the water inlet end of the detection channel 525. The water outlet pipeline 90 is connected between the water outlet end of the detection channel 525 and the water inlet 12a of the cleaning assembly 10.

[0051] When the cleaning robot is in the cleaning mode, the water in the clean water tank 30 sequentially passes through the water tank water outlet 30b, the connecting pipe 70, the detection channel 525 of the detection module 50, the water outlet pipeline 90, and finally enters the cleaning assembly 10 through the water inlet 12a to supply water to the cleaning assembly 10.

[0052] In this way, the clean water tank 30, the connecting pipe 70, and the detection channel 525 are interconnected to form a U-shaped channel (as shown by the dotted line in Figure 3 ), the water level in the detection channel 525 changes following the water level in the clean water tank 30. By detecting the real-time water level in the detection channel 525, the detection unit 54 can obtain the water level condition in the clean water tank 30, thereby realizing the functions of water shortage detection and water full detection through one detection unit 54, and accurately controlling the switching of the cleaning robot between the cleaning mode and the water replenishment mode. Through the setting of the U-shaped channel combined with the detection unit 54, the above-mentioned cleaning device 100 achieves the effect of low-cost liquid level detection of the cleaning robot, and the overall structure is simple, reducing the production cost of the cleaning device 100.

[0053] Specifically, when the cleaning robot is working properly in the cleaning mode, there is cleaning water in the water tank 30 at this time. Therefore, the water in the water tank 30 sequentially passes through the water tank outlet 30b, the connecting pipe 70, and the detection channel 525 and flows into the water outlet pipeline 90. At this time, the real-time water level in the detection channel 525 reaches the preset water level, and the detection unit 54 sends a water full signal to the main body of the machine. When the cleaning water in the water tank 30 is completely consumed and the real-time water level in the detection channel 525 is lower than the preset water level, the detection unit 54 sends a water shortage signal to the main body of the machine, and the cleaning robot switches to the water replenishment mode and moves to the base station for water replenishment. When the water tank 30 is refilled with cleaning water again and the real-time water level in the detection channel 525 reaches the preset water level again, the detection unit 54 sends a water full signal to the main body of the machine, and the cleaning robot switches to the cleaning module and stops water replenishment.

[0054] It can be understood that due to a slight delay in the transmission of the detection signal, after the detection unit 54 detects that the real-time water level in the detection channel 525 reaches the preset water level, the base station will continue to supplement a small amount of cleaning water to the water tank 30. Therefore, in some embodiments, when the highest water level of the connecting pipe 70 is not higher than the preset water level of the detection channel 525, the installation height of the detection module 50 needs to be set so that the preset water level of the detection channel 525 is lower than the highest water level of the water tank 30. In other embodiments, when the highest water level of the connecting pipe 70 is higher than the preset water level of the detection channel 525, the highest water level of the connecting pipe 70 is lower than the highest water level of the water tank 30, and the installation height of the detection module 50 does not need to be considered.

[0055] It can be understood that when comparing the water levels of the connecting pipe 70, the detection channel 525, and the water tank 30, the three water levels are the height differences relative to the same reference plane. For example, in Figure 4 , the height difference between the highest water level of the water tank 30 and the preset water level of the detection channel 525 is h.

[0056] Please refer to Figure 3 and Figure 5 shown. Specifically, in an embodiment, the connecting pipe 70 first extends horizontally from the water tank outlet 30b towards one side of the water tank 30, and then bends upwards until it is connected to the detection channel 525. At this time, the connecting pipe 70 is completely below the detection unit 54, the highest water level of the connecting pipe 70 is lower than the preset water level of the detection channel 525, and the preset water level of the detection channel 525 is lower than the highest water level of the water tank 30. In this embodiment, due to the requirements for the installation position of the detection module 50, higher requirements are put forward for the overall structural arrangement of the cleaning device 100, but the length of the connecting pipe 70 is shorter, saving production costs.

[0057] Please refer to Figure 3 and Figure 6As shown, in another embodiment, the connecting pipe 70 first extends horizontally from the water outlet 30b of the water tank towards one side of the clean water tank 30, then bends upwards and then bends horizontally until it is connected to the detection channel 525. At this time, the highest water level of the connecting pipe 70 is equal to the preset water level of the detection channel 525. In this embodiment, due to the requirements for the installation position of the detection module 50, higher requirements are put forward for the overall structural layout of the cleaning device 100, but the length of the connecting pipe 70 is shorter, thus saving production costs.

[0058] Please refer to Figure 3 and Figure 7 As shown, in another embodiment, the connecting pipe 70 first extends horizontally from the water outlet 30b of the water tank towards one side of the clean water tank 30, then bends upwards until it is higher than the detection channel 525 in the height direction but lower than the highest water level of the clean water tank 30, and then bends downwards until it is connected to the detection channel 525. At this time, the highest water level of the connecting pipe 70 is higher than the preset water level of the detection channel 525. In this embodiment, there are no requirements for the installation position of the detection module 50, but the length of the connecting pipe 70 is longer, thus increasing production costs.

[0059] It should be noted that Figure 5 , Figure 6 and Figure 7 only reflect the relative height relationship between the detection module 50 and the clean water tank 30 and the general extension direction of the connecting pipe 70, rather than the actual structure of the cleaning device 100.

[0060] Please continue to refer to Figures 1 to 4 , the clean water tank 30 has a cubic shell structure. In the following embodiments, the length direction of the clean water tank 30 is defined as the first direction (i.e., the X direction in Figure 1 ), the width direction of the clean water tank 30 is defined as the second direction (i.e., the Y direction in Figure 1 ), and the height direction of the clean water tank 30 is defined as the third direction (i.e., the Z direction in Figure 1 ). The first direction, the second direction, and the third direction are perpendicular to each other in pairs, and the third direction extends vertically. In the following embodiments, the bottom and the top of the clean water tank 30 refer to the opposite ends of the clean water tank 30 in the third direction, and in the Z-axis direction in Figure 1 , the top of the clean water tank 30 is located above the bottom. It can be understood that the shape of the clean water tank 30 is not limited to this, and it can be set as needed to meet different requirements.

[0061] Furthermore, water tank inlets 30a and water tank outlets 30b are respectively provided on opposite sides of the clean water tank 30 in the first direction, and the water tank inlet 30a is located at the top of the clean water tank 30. In this way, the base station can inject water into the clean water tank 30 through the water tank inlet 30a.

[0062] The cleaning assembly 10 is located below the clean water tank 30 in the third direction, and includes a water circuit board 12, a dirt scraping plate 14, a dirt collection tank 16, and two cleaning members 18.

[0063] The water circuit board 12 has a long strip-shaped plate structure. The length direction of the water circuit board 12 extends along the first direction, the width direction of the water circuit board 12 extends along the second direction, and the thickness direction of the water circuit board 12 extends along the third direction. The water circuit board 12 is provided with a water inlet 12a and a first overflow port 12b on the upper surface facing the clean water tank 30 in the third direction, and a plurality of water distribution ports are provided on the lower surface of the water circuit board 12 facing away from the clean water tank 30.

[0064] The dirt scraping plate 14 is stacked on one side of the water circuit board 12 facing away from the clean water tank 30 in the third direction. The dirt scraping plate 14 has a long strip-shaped plate structure. The length direction of the dirt scraping plate 14 extends along the first direction, the width direction of the dirt scraping plate 14 extends along the second direction, and the thickness direction of the dirt scraping plate 14 extends along the third direction. The dirt scraping plate 14 is provided with a communicating second overflow port 14a, and the first overflow port 12b is correspondingly communicated with the second overflow port 14a to form an overflow port.

[0065] The dirt collection tank 16 is stacked on one side of the dirt scraping plate 14 facing away from the water circuit board 12 in the third direction. The dirt collection tank 16 has a long strip-shaped housing structure. The length direction of the dirt scraping plate 14 extends along the first direction, the width direction of the dirt scraping plate 14 extends along the second direction, and the thickness direction of the dirt scraping plate 14 extends along the third direction. One end of the dirt collection tank 16 facing the dirt scraping plate 14 is open, and the open end of the dirt collection tank 16 extends from one end of the dirt collection tank 16 to the other end along the length direction of the dirt collection tank 16.

[0066] The two cleaning members 18 are respectively rotatably provided on opposite sides in the width direction of the dirt collection tank 16, and the rotation axis of the cleaning member 18 extends along the first direction. When the cleaning robot is in the cleaning mode, the cleaning water can enter the water circuit board 12 through the water inlet 12a, and then flow into the cleaning member 18 through the water distribution ports. The two side edges of the dirt scraping plate 14 in the second direction are in contact with the outer circumferential surface of the cleaning member 18. The sewage generated during the cleaning process by the cleaning member 18 can be scraped off by the dirt scraping plate 14 and collected by the dirt collection tank 16. When the cleaning robot is in the water replenishing mode, the excess cleaning water can enter the dirt collection tank 16 through the first overflow port 12b and the second overflow port 14a.

[0067] It can be understood that the structure of the cleaning assembly 10 is not limited to this, and can be set as needed to meet different cleaning requirements of the cleaning robot.

[0068] Please refer to Figure 4 、 Figure 8 、 Figure 9 and Figure 10, the detection module 50 is located on one side of the water purification tank 30 in the first direction, and includes a detection main body 52 and a detection unit 54.

[0069] The detection main body 52 includes a first main body 521 and a second main body 523. The first main body 521 and the second main body 523 are mutually connected in the third direction to form a detection channel 525. The first main body 521 is installed on the water purification tank 30 through fasteners such as screws. The first main body 521 and the second main body 523 can be hermetically connected by ultrasonic welding, or a seal can be installed between the first main body 521 and the second main body 523. The seal is in interference fit with the first main body 521 and the second main body 523 to close the gap therebetween. It can be understood that the connection method between the first main body 521 and the second main body 523 is not limited. In some other embodiments, the first main body 521 and the second main body 523 can also be mutually connected by fasteners or buckles, as long as a sealed detection channel 525 is formed.

[0070] The detection channel 525 extends substantially along the second direction. The middle position of the detection unit 54 extends in a zigzag manner to form a "V" - shaped structure facing the water purification tank 30. The channel wall on the side of the detection channel 525 facing away from the water purification tank 30 has a reflecting surface 5252 extending in a zigzag manner. The detection unit 54 is used to emit detection light to the reflecting surface and receive the detection light reflected by the reflecting surface 5252. When the real - time water level in the detection channel 525 does not reach the preset water level, the light intensity of the detection light reflected by the reflecting surface 5252 to the detection unit 54 is relatively large, so the detection unit 54 emits a water - full signal. When the real - time water level in the detection channel 525 reaches the preset water level, the presence of water changes the reflectivity of the reflecting surface 5252, resulting in a significant decrease in the light intensity of the detection light reflected by the reflecting surface 5252 to the detection unit 54. Therefore, the detection unit 54 emits a water - shortage signal.

[0071] Furthermore, the reflecting surface 5252 includes a first sub - reflecting surface 5252a and a second sub - reflecting surface 5252b arranged at an angle. The acute - angle formed by the first sub - reflecting surface 5252a and the plane perpendicular to the second direction is 45°, and the acute - angle formed by the second sub - reflecting surface 5252b and the plane perpendicular to the second direction is 45°. The detection light emitted by the detection unit 54 can be reflected back to the detection unit 54 through the reflections of the first sub - reflecting surface 5252a and the second sub - reflecting surface 5252b in sequence.

[0072] On one side of the second main body 523 facing away from the first main body 521, there is an installation groove. The detection unit 54 includes a circuit board 541, a transmitter 543 and a receiver 545 installed on one side of the circuit board 541. The transmitter 543 and the receiver 545 are received in the installation groove of the second main body 523. The transmitter 543 and the receiver 545 are spaced apart in the second direction. The transmitter 543 is used to emit detection light into the detection channel 525, and the receiver 545 is used to receive the detection light reflected back from the detection channel 525.

[0073] In some embodiments, the detection module 50 further includes a light shielding member 56. The light shielding member 56 covers the outside of the transmitter 543 and the receiver 545 and separates the transmitter 543 and the receiver 545 from each other, thereby preventing the transmitter 543 and the receiver 545 from interfering with each other, and further improving the detection accuracy of the detection unit 54.

[0074] Please refer back to Figures 1 to 4 , the water outlet pipeline 90 includes a control valve 92 and a water pump 94. The control valve 92 includes a valve water inlet 92a, a first valve water outlet 92b and a second valve water outlet 92c. The valve water inlet 92a selectively communicates with the first valve water outlet 92b and the second valve water outlet 92c, and the valve water inlet 92a is connected to the water outlet end of the detection channel 525 through a pipeline. The water inlet end of the water pump 94 is connected to the first valve water outlet 92b through a pipeline, the water outlet end of the water pump 94 is connected to the water inlet 12a of the water circuit board 12 of the cleaning assembly 10 through a pipeline, and the second valve water outlet is connected to the overflow port of the cleaning assembly 10 through a pipeline.

[0075] In this way, as shown in combination with Figure 1 , Figure 3 and Figure 11 , when the floor cleaning robot is in the normal working state in the cleaning mode, under the suction action of the water pump 94, the water in the clean water tank 30 flows out from the water tank outlet 30b, passes through the connecting pipe 70, the detection channel 525 of the detection module 50, the valve water inlet 92a, and the first valve water outlet 92b in sequence and enters the water pump 94, and then flows into the water inlet 12a of the cleaning assembly 10 through the water outlet end of the water pump 94.

[0076] In combination with Figure 1 , Figure 3 and Figure 12 shown, when the floor cleaning robot is in the water replenishing mode, the excess water can flow out from the water tank outlet 30b, and pass through the connecting pipe 70, the detection channel 525 of the detection module 50, the valve water inlet 92a, and the second valve water outlet 92c in sequence and enter the overflow port of the cleaning assembly 10.
