[0026] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0027] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0028] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0029] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0030] The cleaning mode intelligent switching system and the cleaning robot of the present application are now described in detail with reference to the accompanying drawings.

[0031] Please refer to Figure 1 and Figure 2 The cleaning robot 200 provided in the embodiment of the present application includes a body 201, a driving wheel 202, and a cleaning mode intelligent switching system 100 applied to the cleaning robot 200. The driving wheel 202 is arranged at the bottom of the body 201 and is used to drive the body 201 to walk on the ground; the cleaning mode intelligent switching system 100 is used to automatically switch the cleaning mode when the body 201 is cleaning and walking, and can realize the automatic switching between the vacuuming mode of dry cleaning and the wet cleaning mode of adding water when the cleaning robot 200 encounters a carpet area and a non-carpet area.

[0032] like Figure 2As shown, the cleaning mode intelligent switching system 100 includes a main control board 10, a detection element 20 for detecting the properties of the ground, a wet cleaning unit 40, and a dust suction unit 30 for dust suction. The wet cleaning unit 40 includes a first liquid supply unit 50 for providing clean water, a second liquid supply unit 60 for providing cleaning liquid, and a brush unit 90, and the main control board 10 is connected to the detection element, the dust suction unit 30, the first liquid supply unit 50, the second liquid supply unit 60, and the brush unit 90. The main control board 10 is used to drive the dust suction unit 30 to work for dry cleaning when the detection element detects that the ground belongs to a carpeted ground, and is used to drive the wet cleaning unit 40 to work when the detection element detects that the ground belongs to a non-carpeted ground.

[0033] In one embodiment of the application, the detection element is an ultrasonic sensor detection device. The above-mentioned non-carpet area is a normal floor including smooth floors such as wooden floors, floor tiles, and ceramic tiles, and the carpet area is a non-smooth area formed by materials such as plush and wool on the floor. The ultrasonic sensor transmits an ultrasonic signal to the floor and receives an echo signal reflected by the floor. The ultrasonic sensor feeds the echo signal back to the main control board 10. Since the waveforms of the echo signals of the smooth floor and the non-smooth floor are different, the main control board 10 can analyze whether the floor is a non-smooth area of ​​the carpet or a smooth area of ​​the non-carpet according to the echo signal. The analysis method of the main control board 10 can be any existing method.

[0034] In the cleaning mode intelligent switching system 100, during the cleaning process, when the detection element 20 detects that the floor is a carpet area, the main control board 10 drives the vacuum module to work in the dry cleaning mode, and when the detection element 20 detects that the floor is a non-carpet area, the control board drives the unit that can provide clean water and cleaning liquid to work. In this way, the cleaning mode intelligent switching system 100 can automatically detect the floor properties and automatically switch the cleaning mode without manually adjusting the cleaning mode, which is beneficial to the user experience and also conducive to realizing unattended intelligent cleaning functions.

[0035] Combined with reference Figures 2 to 4 The dust collection unit 30 includes a fan 31, a hose 33, a cover shell 34, a dust collection roller brush 35, a dust collection motor 36 and a dust box 32 for placing garbage. The dust collection roller brush 35 is arranged in the accommodating chamber opened in the cover shell 34. One end of the hose 33 is connected to the dust collection port on the cover shell 34 that is connected to the accommodating chamber, and the other end of the hose 33 is connected to the dust box 32. The dust collection motor 36 and the fan 31 are both connected to the main control board 10. The fan 31 and the dust box 32 have airflow communication and are used to extract the air in the dust box 32 to generate negative pressure in the dust box 32. The dust collection motor 36 is connected to the dust collection roller brush 35 and is used to drive the dust collection roller brush 35 to rotate. When the dust collection roller brush 35 rotates, the dust brought up by it enters the dust box 32 from the dust collection port. Among them, Figure 3The arrows in the figure indicate the flow direction of dust following the gas during vacuuming when there is negative pressure.

[0036] In the dust collection module, the fan 31 generates negative pressure in the dust box 32, and when the dust collection motor 36 drives the dust collection roller brush 35 to rotate, the ground garbage brought up by the dust collection roller brush 35 is sucked into the dust box 32 from the dust collection port. The dust collection module cleans dust by negative pressure suction.

[0037] The fan 31 and the dust box 32 are arranged in the body 201 , and the cover shell 34 , the dust collection roller brush 35 arranged in the cover shell 34 , and the dust collection motor 36 are all arranged at the bottom of the body 201 .

[0038] Combined with reference Figure 2 and Figure 5 The first liquid supply unit 50 includes a clean water tank 51 for storing water, a water outlet pipe 52, and a diaphragm pump 53 arranged on the water outlet pipe 52 and connected to the main control board 10; the clean water in the clean water tank 51 is discharged through the water outlet pipe 52 and the main control board 10 is used to control the diaphragm pump 53 to switch the water outlet pipe 52.

[0039] Furthermore, the second liquid supply unit 60 includes a cleaning box 61 for storing cleaning liquid, a liquid outlet pipe 62, and a peristaltic pump 63 arranged on the liquid outlet pipe 62 and connected to the main control board 10.

The liquid treated by electrolysis is discharged through the water outlet 80 to the ground. The electrolysis module 70 is used to electrolyze water to produce chloride ions with a sterilizing effect, and the water with chloride ions is sprayed on the ground through the water outlet pipe so as to sterilize the ground during the cleaning module cleaning process. Among them, the electrolysis module 70 is any device in the prior art that can produce chloride ions by electrolyzing water. Among them, the clean water tank 51, the diaphragm pump 53, the cleaning box 61, the peristaltic pump 63, and the electrolysis module 70 are all arranged in the body 201.

[0041] Combined with reference Figure 2 , Figure 6 and Figure 8The brush assembly unit 90 includes a lifting drive device 91 connected to the main control board 10, a rotation drive device 92 connected to the main control board 10, a connecting rod assembly 93 connected to the lifting drive device 91, a cleaning brush 94 connected to the connecting rod assembly 93, and a garbage box 95 arranged on one side of the cleaning brush 94. The main control board 10 is used to control the lifting drive device 91 to drive the connecting rod assembly 93 to move so as to drive the cleaning brush 94 to move up and down relative to the ground. The rotation drive device 92 is connected to the cleaning brush 94 and is used to drive the cleaning brush 94 to rotate and clean the garbage into the garbage box 95.

[0042] In order to prevent unnecessary wear of the cleaning brush 94, when the brush set unit 90 is not needed for cleaning, the cleaning brush 94 should be kept out of contact with the ground, so the brush set unit 90 is not used. When the brush set unit 90 is needed, the main control board 10 controls the lifting drive device 91 to drive the connecting rod assembly 93 to move, so as to drive the cleaning brush 94 to move toward the ground, so that the cleaning brush 94 can contact the ground, and then the cleaning brush 94 cleans the garbage on the ground.

[0043] In one embodiment of the application, the rotation driving device 92 can be a motor, which drives the cleaning brush 94 to rotate and clean.

[0044] Combined with reference Figures 8 to 10 The connecting rod assembly 93 includes a fixed plate 931, a movable plate 932, a plurality of connecting rods 933, and a driving plate 934. Specifically, the fixed plate 931 is arranged at the bottom of the cleaning robot 200, specifically at the bottom of the body 201 of the cleaning robot 200; the movable plate 932 is arranged opposite to the fixed plate 931, and a cleaning brush 94 can be arranged on the movable plate 932 of a connecting rod assembly 93; the two ends of each connecting rod 933 are respectively connected to the fixed plate 931 and the movable plate 932; the driving plate 934 is arranged between the fixed plate 931 and the movable plate 932, and one side of the driving plate 934 is movably connected to the fixed plate 931 and the other side is connected to the movable plate 932.

[0046] It can be understood that the up and down directions are relative to the ground on which the cleaning robot 200 is placed, and the left and right directions intersect with the up and down directions. Further, the up and down directions can be understood as two directions on the Y-axis in a rectangular coordinate system, and the left and right directions are two directions on the X-axis in the rectangular coordinate system.

[0047] It is worth mentioning that when the cleaning brush 94 is needed, the electric cylinder 911 is used to drive the telescopic rod 912 to extend relative to the electric cylinder 911, and the connecting shaft acts on the driving plate 934 to rotate toward the ground with the connection between the driving plate 934 and the fixed plate 931 as a fulcrum, thereby driving the movable plate 932 connected to the drive to move downward toward the ground, thereby driving the cleaning brush 94 on the movable plate 932 to be pressed down; on the contrary, when the cleaning brush 94 is not needed to work, in order to prevent the squeegee assembly 30 and the cleaning assembly from still rubbing against the ground and causing unnecessary damage, the electric cylinder 911 is used to drive the telescopic rod 912 to retract relative to the electric cylinder 911, and the connecting shaft acts on the driving plate 934 to rotate away from the ground with the connection between the driving plate 934 and the fixed plate 931 as a fulcrum, thereby driving the movable plate 932 connected to the drive to move upward toward the ground, thereby driving the cleaning brush 94 on the movable plate 932 to be lifted.
