[0026] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] See also Figure 1 and Figure 2As shown, the present invention discloses an intelligent sweeping cleaning device 100, which can automatically move along a working direction to clean the floor. The intelligent sweeping cleaning device 100 includes a housing 10, a walking wheel 20 mounted on the housing 10, a first cleaning unit 30 mounted on the housing 10, a second cleaning unit 40 mounted on the housing 10 and spaced apart from the first cleaning unit 30, and a dust box 50 mounted on the housing 10. In this embodiment, the dust box 50 is arranged between the first cleaning unit 30 and the second cleaning unit 40 along the working direction of the intelligent sweeping cleaning device 100; of course, in other embodiments, the intelligent sweeping cleaning device 100 may also be provided with only one cleaning unit.

[0028] The intelligent sweeping and cleaning device 100 of the present application is a robot that can clean independently. In the present embodiment, it is a sweeping and mopping robot. Of course, it can also be other suitable robots or equipment that automatically perform cleaning work, which is not limited here.

[0029] See also Figure 3 and Figure 4 Combined with Figure 2 As shown, the housing 10 includes a main body 11 disposed inside, a top housing 12 mounted on the upper part of the main body 11, a bottom housing 13 mounted on the lower part of the main body 11, and a front housing 14 mounted on the front part of the main body 11. The dust box 50 can be mounted to or removed from the housing 10 in the up and down directions. The intelligent sweeping cleaning device 100 further includes a water tank 60 mounted on the rear side of the main body 11. In this embodiment, the front housing 14 is movably mounted on the main body 11. Specifically, the front housing 14 can move relative to the main body 11 in the up and down directions. For example, when bumping, the front housing 14 can move up and down due to the influence of gravity.

[0030] The walking wheels 20 are provided in a pair, and the pair of walking wheels 20 are arranged at intervals in a transverse direction perpendicular to the working direction of the intelligent sweeping and cleaning device 100. Each walking wheel has an independent driving motor, so that the intelligent sweeping and cleaning device 100 can be driven to move in the working direction to clean the floor, and can also turn or retreat when encountering obstacles. The dust box 50 is arranged between the pair of walking wheels 20 in the transverse direction.

[0031] The first cleaning unit 30 is a sweeping roller brush, and the first cleaning unit 30 is arranged in front of the dust box 50 along the working direction. The first cleaning unit 30 can automatically rise and fall relative to the housing 10 in the up and down direction perpendicular to the working direction and the lateral direction, so that when the intelligent sweeping cleaning device 100 moves during work, if the working environment changes, such as the floor tiles become floors, carpets, etc., or when encountering obstacles, the corresponding sensing unit can sense the environmental changes, thereby triggering the corresponding driving unit, so that the first cleaning unit 30 can move up and down to adjust its position relationship with the working ground to adapt to the new working environment or turn to avoid obstacles. The intelligent sweeping cleaning device 100 further includes a front universal wheel 70 arranged on the housing 10, and the front universal wheel 70 can work with the walking wheel 20 to cooperate with the sweeping roller brush. The rear end of the sweeping roller brush is connected to the dust box 50, so that when the first cleaning unit 30 is working, the swept garbage can be stored in the dust box 50.

[0032] The second cleaning unit 40 is a floor-scrubbing roller brush, and the second cleaning unit 40 is arranged behind the dust box 50 along the working direction. The second cleaning unit 40 can automatically rise and fall relative to the housing 10 in the up and down direction, so that when the intelligent floor-sweeping cleaning device 100 moves during work, if the working environment changes, such as the floor tiles become floors, carpets, etc., or when encountering obstacles, the corresponding sensing unit can sense the environmental changes, thereby triggering the corresponding driving unit, so that the second cleaning unit 40 can move up and down to adjust its positional relationship with the working ground to adapt to the new working environment or turn to avoid obstacles. The intelligent floor-sweeping cleaning device 100 further includes a rear universal wheel 80 arranged on the housing 10, and the rear universal wheel 80 can work with the walking wheel 20 to cooperate with the second cleaning unit 40. The second cleaning unit 40 is to perform preliminary cleaning of the garbage that needs to be removed on the ground before the first cleaning unit 30 performs the next step of floor-scrubbing operation, avoiding the situation where it is difficult to scrub the floor when there is too much garbage, and improving the cleaning cleanliness and work efficiency of the intelligent floor-sweeping cleaning device 100.

[0033] The water tank 60 includes a clean water tank 61 and a wastewater collecting device 62 disposed behind the second cleaning unit 40. The clean water tank 61 is disposed above the wastewater collecting device 62. Clean water can be contained in the clean water tank 61 so that when the second cleaning unit 40 performs floor scrubbing, water can be supplied to the second cleaning unit 40, thereby enhancing the cleaning ability of the second cleaning unit 40. In addition, the clean water tank 61 is disposed above the wastewater collecting device 62 so that the clean water can be guided to the second cleaning unit 40 by gravity.

[0034] The sewage collecting device 62 is arranged below the clean water tank 61, so as to be closer to the second cleaning unit 40, thereby facilitating the collection of sewage generated by the second cleaning unit 40 during floor washing, so that the floor can maintain a high degree of dryness after the second cleaning unit 40 completes the floor washing operation.

[0035] The water tank 60 is further provided with a clean water injection port 610 connected to the clean water tank 61, and a sewage pumping port 620 connected to the sewage collecting device 63, so that the intelligent sweeping and cleaning device 100 can be automatically connected to the corresponding base station, so that the base station can automatically inject clean water into the clean water tank 61 through the clean water injection port 610, and the base station can also automatically extract the sewage collected by the sewage collecting device 62 through the sewage pumping port 620, so that the intelligent sweeping and cleaning device 100 can work for a long time and repeatedly.

[0036] See also Figures 5 to 10 As shown, in this embodiment, the intelligent sweeping cleaning device 100 further includes a detection control module 90. The first cleaning unit 30 and the second cleaning unit 40 are both movably mounted on the housing 10, and the detection control module 90 is used to control the first cleaning unit 30 and / or the second cleaning unit 40 to move relative to the housing 10 to adjust to a suitable working position. The detection control module 90 includes a first driving structure 91 for controlling the first cleaning unit 30 to move relative to the housing 10 to adjust to a suitable working position, and a second driving structure 92 for controlling the second cleaning unit 40 to move relative to the housing 10 to adjust to a suitable working position.

[0037] The first cleaning unit 30 includes a first connecting rod 31 cantilevered forward from the middle area thereof. The first driving structure 91 includes a first eccentric wheel 910 connected to the first connecting rod 31 and capable of driving the first connecting rod 31 to move, and a first driving motor (not shown) that drives the first eccentric wheel 910 to work. The first cleaning unit 30 includes first extension parts 32 extending backward from both ends thereof, and the rear end of the first extension part 32 can be rotatably connected to the housing 10, thereby forming a fulcrum for the relative movement of the first cleaning unit 30 and the housing 10.

[0038] The detection control module 90 includes a first detection module 93, and the first detection module 93 includes a first upper touch switch 931 disposed on the upper side of the first connecting rod 31, and a first lower touch switch 932 disposed on the lower side of the first connecting rod 31. The first upper touch switch 931 and the first lower touch switch 932 are both stop switches. When the first eccentric wheel 910 drives the first connecting rod 31 to move up and down, it can touch the first upper touch switch 931 or the first lower touch switch 932 to trigger the first drive motor to stop working, thereby stopping the movement of the first cleaning unit 30. When it is necessary to rise, the first drive motor drives the first eccentric wheel 910 to rotate half a circle or other number of circles, so that the first connecting rod 31 is lifted to the highest point, triggering the first upper touch switch 931, and the first cleaning unit 30 completes the rise. When it is necessary to descend, the first drive motor drives the first eccentric wheel 910 to rotate, so that the first connecting rod 31 descends to the lowest point, triggering the first lower touch switch 932, and the first cleaning unit 30 completes the descent.

[0039] The second cleaning unit 40 includes a second connecting rod 41 cantilevered forward from the middle area thereof. The second driving structure 92 includes a slider 920 matched with the second connecting rod 41, a second eccentric wheel 921 connected to the slider 920 and capable of driving the slider 920 to move and thus drive the second connecting rod 41 to move, and a second driving motor (not shown) driving the second eccentric wheel 921 to work. A detection portion 922 extends from one side of the slider 920. The detection control module 90 also includes a second detection module 94, which includes a second upper touch switch 941 arranged on the upper side of the detection part 922, and a second lower touch switch 942 arranged on the lower side of the detection part 922. When the second eccentric wheel 921 drives the slider 920 to move up and down, the slider 920 drives the second connecting rod 41 to move, and at the same time drives the detection part 922 to move and can touch the second upper touch switch 941 or the second lower touch switch 942, thereby triggering the second driving motor to stop working, and then the second cleaning unit 40 stops moving.

[0040] When it is necessary to rise, the second driving motor drives the second eccentric wheel 921 to rotate, thereby driving the slider 920 and the second connecting rod 41 to move upward, so that the second connecting rod 41 is lifted to the highest point, the detection part 922 triggers the second upper touch switch 941, and the second cleaning unit 40 completes the rise. When it is necessary to descend, the second driving motor drives the second eccentric wheel 921 to rotate, thereby driving the slider 920 and the second connecting rod 41 to move downward, so that the second connecting rod 41 descends to the lowest point, the detection part 922 triggers the second lower touch switch 942, and the second cleaning unit 40 completes the descent. The second cleaning unit 40 also includes a plurality of telescopic hoses 44 connected between the second cleaning unit 40 and the water tank 60, so that when the second cleaning unit 40 moves relative to the housing 10, the water supply connection between the water tank 60 and the second cleaning unit 40 can be stable and reliable.

[0041] The second cleaning unit 40 includes protrusions 42 extending upward from both ends thereof, and the protrusions 42 are provided with first receiving grooves 420. The housing 10 is provided with corresponding second receiving grooves 101. The second cleaning unit 40 includes a second extension 43 connecting the corresponding first receiving grooves 420 and the second receiving grooves 101, so as to form a fulcrum for the relative movement of the second cleaning unit 40 and the housing 10. When the second cleaning unit 40 is adjusted, the second extension 43 rotates relative to the second cleaning unit 40 and the housing 10. In this embodiment, the second extensions 43 connecting each first receiving groove 420 and the corresponding second receiving groove 101 are spaced apart and arranged in pairs along the up-down direction.

[0042] The intelligent sweeping and cleaning device 100 further includes a detection member 102 installed between the main body 11 and the front shell 14. When the intelligent sweeping and cleaning device 100 hits an obstacle or bumps during automatic walking, the front shell 14 will deform or displace relative to the main body 11, thereby squeezing the detection member 102 to trigger the detection member 102 to work, and transmit a signal to one or both of the first drive motor and the second drive motor according to the situation, so as to drive one or both of the first cleaning unit 30 and the second cleaning unit 40 to start lifting and lowering movement, so that the intelligent sweeping and cleaning device 100 can avoid obstacles or adjust to a position that conforms to the changed environment.

[0043] Specifically, the working method of the intelligent sweeping cleaning device 100 includes: when the working environment of the intelligent sweeping cleaning device 100 changes so that the front shell 14 and the main body 11 generate relative movement, and the relative movement triggers the detection element 102, the intelligent sweeping cleaning device 100 controls the corresponding cleaning unit to adjust to a position suitable for working in the changed environment. The intelligent sweeping cleaning device 100 can adjust one of the first cleaning unit 30 and the second cleaning unit 40 to a working position and the other to a non-working position, or both the first cleaning unit 30 and the second cleaning unit 40 to a working position according to self-detection or manual setting.

[0044] After receiving the command, the first driving structure 91 drives the first eccentric wheel 910 to rotate and drives the first connecting rod 31 to move, thereby driving the first cleaning unit 30 to adjust its position. The first eccentric wheel 910 drives the first connecting rod 31 to move upward and touch the first upper touch switch 931, and then stops moving upward. When the first eccentric wheel 910 drives the first connecting rod 31 to move downward and touch the first lower touch switch 932, it stops moving downward.

[0045] After receiving the command, the second driving structure 92 will drive the second eccentric wheel 921 to rotate, drive the slider 920 to further drive the second connecting rod 41 to move, and then drive the second cleaning unit 40 to adjust its position. The second eccentric wheel 921 drives the detection part 922 to move upward until the second upper trigger switch 941 is triggered, and then the upward movement will stop. The second eccentric wheel 921 drives the detection part 922 to move downward until the second lower trigger switch 942 is triggered, and then the downward movement will stop.

[0046] See also Figure 3 and Figure 4 As shown, the intelligent sweeping cleaning device 100 further includes a plurality of elastic members 103 that elastically act on the front shell 14, so that after the intelligent sweeping cleaning device 100 avoids obstacles and the environment in which the intelligent sweeping cleaning device 100 is located is stable, the elastic member 103 will return the front shell 14 to its initial position. In this embodiment, the elastic member 103 is an elongated coil spring, and of course, it can also be other suitable springs or other parts that allow the front shell 14 to return to its initial position. In addition, when the intelligent sweeping cleaning device 100 detects that the working environment is a carpet based on its own detection, such as through a laser radar or other detection element, it can control the second cleaning unit 40 to rise and not work, and only allow the first cleaning unit 30 to descend to a suitable position to work; or the intelligent sweeping cleaning device 100 can be set to only allow the first cleaning unit 30 to work, or only allow the second cleaning unit 40 to work, or both to work at the same time through an electronic device such as a mobile phone.

[0047] To summarize, the intelligent sweeping and cleaning device 100 of the present invention is provided with a detection control module 90, and the first cleaning unit 30 and the second cleaning unit 40 are movably mounted on the housing 10, so that when the working environment of the intelligent sweeping and cleaning device 100 changes, the corresponding cleaning unit can be controlled to move relative to the housing 10 to adjust to a suitable working position, thereby enabling the intelligent sweeping and cleaning device 100 of the present invention to have a strong obstacle surmounting capability and to adapt to complex and changeable ground environments.
