It should be noted that, in order to avoid obscuring the present invention with unnecessary details, only the structures and/or processing steps closely related to the aspects of the present invention are shown in the drawings, and other details not closely related to the present invention are omitted.

In addition, it should be further noted that the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.

As shown in fig. 1 to 22, the present invention discloses an automatic cleaning apparatus 100 which can move forward to perform an environmental cleaning work of a floor surface. The automatic cleaning apparatus 100 includes a first portion 101 and a second portion 102 detachably mounted on the first portion 101. The first portion 101 includes a main body 10, a traveling wheel 20 mounted on the main body 10, and a cleaning unit 30 disposed in front of the traveling wheel 20. At least one end of the cleaning unit 30 is beyond or flush with a corresponding end of the traveling wheel 20 in a lateral direction perpendicular to the forward direction, outside the lateral direction. Therefore, when the automatic cleaning device 100 performs a cleaning motion, the cleaning unit 30 cleans contaminants on the ground before the traveling wheel 20, so that secondary pollution to a cleaned area caused by the traveling wheel 20 sticking to the contaminants is avoided, and the automatic cleaning efficiency of the automatic cleaning device 100 is improved.

The bottom of the second part 102 is provided with a universal wheel 40, and the universal wheel 40 and the travelling wheel 20 jointly support the travelling of the automatic cleaning equipment 100 during automatic cleaning.

As shown in fig. 1 to 7, the first portion 101 includes a first top surface 1010, a first bottom surface 1011, and a first step surface 1012 between the first top surface 1010 and the first bottom surface 1011. The second portion 102 includes a second top surface 1020, a second bottom surface 1021, and a second step surface 1022 between the second top surface 1020 and the second bottom surface 1021. When the second portion 102 is mounted on the first portion 101, the first top surface 1010 is coplanar with the second top surface 1020, the first bottom surface 1011 is coplanar with the second bottom surface 1021, and the first step surface 1012 supports the second step surface 1022. Thus, the first portion 101 forms the automatic cleaning apparatus 100 with the second portion 102. The second portion 102 is a part of the outer contour of the automatic cleaning device 100, and the second portion 102 forms at least a part of the outer surface of the automatic cleaning device 100 in at least three directions. In particular, in the present embodiment, the second top surface 1020 of the second portion 102 forms a portion of the top surface of the automatic cleaning apparatus 100. The second bottom surface 1021 constitutes a portion of the bottom surface of the automatic cleaning apparatus 100. The side surface 1023 of the second portion 102 connecting the second top surface 1020 and the second bottom surface 1021 forms a part of the side surface of the automatic cleaning device 100. The rear face 1024 of the second portion 102, which connects the second top face 1020 and the second bottom face 1021, constitutes the entirety of the rear of the robotic cleaning device 100. Therefore, the automatic cleaning device 100 makes full use of the outline of the part, which is called as a part of the outline of the whole product, reduces the whole size of the product, production materials, molding and assembling processes, and has the advantages of small size, low cost and the like. Of course, the coplanarity described herein is not an absolute coplanarity in terms of data concept, and in the present invention, two coplanar surfaces are mainly used to form an integral surface of a product, which may be an arc, an uneven surface, a wavy surface, or the like.

As shown in fig. 2 and 3, in the present embodiment, the main body 10 is provided at the front end of the automatic cleaning apparatus 100. The traveling wheels 20 (only one example is shown in the drawings) include a pair and are provided at both sides of the main body 10 in a row interval in the lateral direction. The pair of traveling wheels 20 exposes the bottom side of the main body 10 so as to contact the ground to drive the automatic cleaning apparatus to travel automatically. The cleaning unit 30 is mounted on the main body 10 and exposes the bottom side of the main body 10 so as to be able to contact the floor for cleaning of the floor environment. The cleaning device includes a pair of cliff sensors 11 provided at a bottom side of the main body 10 with a gap therebetween, and the pair of cliff sensors 11 are provided on a front side of the cleaning unit 30. The cliff sensor 11 is used to detect a change in the floor environment, such as a change in the floor to a carpet, or a step on the floor that causes the automatic cleaning apparatus 100 to fall down. The number of cliff sensors 11 may be set as desired, and is not limited herein.

As shown in fig. 3 and 10, the cleaning unit 30 is specifically a roll-and-drag module, but may be other suitable modules for floor cleaning, and is not limited thereto. The cleaning unit 30 includes a pair of rolling

brushes

31a and 31b arranged side by side, and the rotational axes of the rolling brushes 31a and 31b are parallel to the rotational axes of the pair of traveling wheels 20. The rotation axes of the pair of roll brushes 31a and 31b are parallel to the ground on which they are operated. Of the pair of roll brushes 31a and 31b, the roll brush 31a disposed on the front side has a diameter larger than that of the other roll brush 31 b. Accordingly, the thicker rolling brush 31a performs coarse cleaning, and the thinner rolling brush 31b performs fine cleaning. The axial dimension of the thicker roller brush 31a is smaller than the axial dimension of the thinner roller brush 31 b. One end of the thicker roll brush 31a is aligned with one end of the thinner roll brush 31b, and the other end is shorter than the other end of the thinner roll brush 31 b. Of course, it may be more specifically necessary to extend both ends of the thinner roller brush 31b beyond the corresponding ends of the thicker roller brush 31 a. The cleaning unit is provided with a recess 32.

As shown in fig. 4 and 5, a recess 12 for accommodating the cleaning unit 30 is recessed toward the inside of the main body 10 at the bottom of the main body 10, and the cleaning unit 30 is accommodated in the recess 12 and protrudes out of the bottom of the main body 10 to clean the floor. An unlocking mechanism 13 is included to take out the cleaning unit 30 from the main body 10 of the automatic cleaning apparatus 100. The unlocking mechanism 13 includes an actuating portion 130 protruding into the recessed portion 12 and acting on the groove 32 of the cleaning unit 30, a pressing portion 131 exposed on the surface of the main body 10 and pressed by a user to remove the cleaning unit 30, and a manipulating portion 132 for converting a pressing operation sensed by the pressing portion 131 into the actuating portion 130 so that the cleaning unit 30 can be removed.

The second portion 102 includes the water tank 50. The universal wheel 40 is disposed at the bottom of the water tank 50. The water tank 50 is detachably mounted to the main body 10. The universal wheel 40 is disposed at the rear side of the pair of road wheels 20 and is located on the centerline of the line connecting the pair of road wheels 20 in the transverse direction. The water tank 50 includes a foul water tank 51 at the bottom and a clean water tank 52 above the foul water tank 51. The clean water tank 52 is isolated from the dirty water tank 51. The water tank 50 includes a removable dirt box 53. The dust box 53 is received in the dirty water tank 51 through the clean water tank 52.

Specifically, the first air suction opening 14 and the second air suction opening 15 are both communicated to the first air duct 54. The opening size of the first suction opening 14 is larger than the opening size of the second suction opening 15.

As shown in fig. 3 and 9, in the present embodiment, the first air duct 54 is disposed in the water tank 50, the first air duct 54 is connected to the dust box 53, and the first air suction opening 14 and the second air suction opening 15 are communicated with the dust box 53. The main body part 10 is provided with the first air suction opening 14 and a second air suction opening 15 located behind the first air suction opening 14, the first air suction opening 14 and the second air suction opening 15 are communicated together in the main body part 10, and the first air suction opening 14 is arranged in the recessed part 12 to suck garbage generated by cleaning of the cleaning unit 30. The cleaning unit 30 includes a carrier 33 provided between the pair of roll brushes 31a and 31b and the recess 12 of the main body 10 to carry the pair of roll brushes, the carrier 33 being provided with an opening 330 corresponding to the first air suction opening 14. The opening 330 is provided closer to the roll brush of the pair of roll brushes 31a and 31b located on the rear side.

An included angle between a normal line of a plane where the first air suction opening 14 is located and an advancing direction of the automatic cleaning device 100 is an obtuse angle, that is, the first air suction opening 14 faces a floor surface where the automatic cleaning device 100 works obliquely, so that when the automatic cleaning device 100 moves forward for cleaning, it is easier to suck the garbage generated by cleaning of the cleaning unit 30. The first suction opening 14 is disposed in the recess 12 accommodating the cleaning unit 30. An included angle between a normal line of a plane where the second air suction opening 15 is located and the advancing direction of the automatic cleaning equipment 100 is a right angle, namely, the second air suction opening 15 is right opposite to or parallel to the ground where the automatic cleaning equipment 100 works, so that secondary pollution can be prevented, the ground can be further cleaned, and meanwhile, the ground can be dried more quickly by the second air suction opening 15. The first air suction opening 14 and the second air suction opening 15 are both communicated with the first air duct 54. The rear end of the first air duct 54 communicates with the dust box 53. The normal of the plane of the first air suction opening 14 and the normal of the plane of the second air suction opening 15 may intersect or be orthogonal.

In this embodiment, the clean water tank 52 includes a bottom wall 520 disposed at the top of the dirty water tank 51, and the bottom wall 520 includes a second groove wall 521 recessed into the clean water tank 52 from a lower surface thereof. The first air duct 54 includes a first slot wall 540 matching with the second slot wall 521, and the first slot wall 540 and the second slot wall 521 together form the first air duct 54. Of course, the bottom wall 520 of the water tank 52 may also be flat, and the first groove wall 540 and the flat bottom wall 520 together form the first air duct.

As shown in fig. 14 to 17, a second air duct 16 is further disposed in the main body 10, one end of the second air duct 16 is communicated with the first air duct 54, and the other end of the second air duct 16 opposite to the first air suction opening 14 is communicated with the second air suction opening 15. Specifically, in the present embodiment, the first air suction opening 14 is directly communicated with the other end of the second air duct 16. In this embodiment, the extending direction of the second air duct 16 is consistent with the normal direction of the plane where the first air suction opening 14 is located. A third air duct 17 is further arranged in the main body portion 10, the size of an opening of the third air duct 17 is smaller than that of an opening of the second air duct 16, and the second air suction opening 15 is communicated with the other end of the second air duct 16 through the third air duct 17. The extending direction of the third air duct 17 forms an acute angle with the advancing direction of the automatic cleaning apparatus 100. The extending direction of the third air duct 17 forms an included angle with the normal of the plane where the second air suction opening 15 is located, and the normal is perpendicular to the ground. The extending direction of the second air duct 16 forms an obtuse angle with the advancing direction of the automatic cleaning device 100. The automatic cleaning apparatus 100 is provided with the first air suction opening 14 and the second air suction opening 15, so that secondary pollution can be prevented and the ground drying speed can be accelerated, thereby improving the cleaning capability of the automatic cleaning apparatus 100. It should be noted that the third air duct 17 is mainly used for drying the ground, and because the opening of the third air duct 17 is small, a filtering structure needs to be arranged between the second air duct 16 and the third air duct 17 to prevent large garbage from entering the second air duct 16 along the third air duct 17, and further, the extending direction of the second air duct 16 is perpendicular to the extending direction of the third air duct 17.

As shown in fig. 18 to 22, the air duct structure or the water tank air duct in the water tank 50 further includes the first air duct 54, a filtering channel 55 communicated with the first air duct 54 for filtering the air transmitted from the first air duct 54, an air exhausting channel 56 communicated with the filtering channel 55 and capable of exhausting the air out of the water tank 50 to the outside, and an air duct control structure 57 for controlling the opening or closing of the air duct structure. The air duct control structure 57 includes a control member 570, an air intake baffle 571 disposed between the first air duct 54 and the filtering channel 55, an air exhaust baffle 572 disposed between the air exhaust channel 56 and the external environment, and a transmission mechanism 573 controlled by the control member 570 to change the states of the air intake baffle 571 and the air exhaust baffle 572. The air duct control structure 57 includes an intermediate transfer structure 574 acting between the transfer mechanism 573 and the intake baffle 571. The transmission mechanism 573 indirectly acts on the intake screen 571 through the intermediate transmission mechanism 574 to change its state. The transmission mechanism 573 directly acts on the exhaust damper 572 to change its state. The air duct control structure 57 includes a plurality of elastic members 575, and the elastic members 575 make the control member 570 not press the transmission mechanism 573, and the air inlet plate 571 and the air outlet plate 572 are in a closed state, at this time, the air duct structure is not through. When the control member 570 is compressed against the elastic force and presses against the transmission mechanism 573, the air inlet plate 571 and the air outlet plate 572 are opened against the elastic force, and the air duct structures are communicated.

In other embodiments of the present invention, because electronic control may exhibit hysteresis or sluggishness, the control member 570 can be controlled by the road wheel 20, specifically, the control member 570 partially extends above the housing 21 of the road wheel 20, when the automatic cleaning device 100 is positioned on the ground, the traveling wheel 20 is supported by the ground, so that the casing 21 triggers the control part 570, thereby driving the air inlet plate 571 and the air outlet plate 572 to open, and when the automatic cleaning device 100 is suspended or taken up by accident, the traveling wheel 20 drives the housing 21 to move downwards under the action of gravity, and is separated from the control member 570, the air inlet baffles 571 and the air outlet baffles 572 are closed under the left and right gravity, that is, the air inlet 571 and the air outlet 572 are linked with the traveling wheels 20.

As shown in fig. 13, specifically, in the present embodiment, the water tank duct communicates with the dust box 53, and the filter passage 55 of the water tank duct is provided in the dust box 53. The filtering passage 55 can retain the sucked garbage in the dust box 53, and the sewage brought by the garbage is discharged into the sewage tank 51. The discharge passage 56 of the tank duct is provided in the foul water tank 51, and the wind discharged from the filtering passage 55 can be discharged to the outside of the water tank 50 through the discharge passage 56. The control member 570 extends beyond the bottom of the water tank 50, so that when the water tank 50 is mounted on the main body 10, the elastic force of the elastic member 575 at the control member 570 is overcome, so that the control member 570 is pressed into the water tank 50 to push the end of the transmission mechanism 573 upward, and the elastic member 575 at the position is an elongated coil spring, but may be other elastic members for realizing the function. The transmission mechanism 573 is a lever structure with a pivot point in the middle, so that the elasticity of an elastic member (not shown) at the transmission mechanism 573 is overcome and the opposite end moves downward. When the water tank 50 is removed from the body 10, the elastic member 575 at the check member 570 pushes the check member 570 outward, so that one end of the transmission mechanism 573 will not be pressed by the check member 570, and the elastic member at the transmission mechanism 573 will restore the transmission mechanism 573 to the original state.

The air inlet baffle 571 is arranged in the dust box 53, the air inlet baffle 571 is a lever structure with a middle pivot, the elastic member 575 at the air inlet baffle 571 makes the air inlet baffle 571 maintain a closed state when not being acted by the transmission mechanism 573, in this embodiment, the elastic member 575 here is a torsion spring, but may be other elastic members for realizing this function. The middle transmission structure 574 includes a first middle transmission structure 5741 disposed outside the dust box 53, and a second middle transmission structure 5742 disposed inside the dust box 53 and acting on the first middle transmission structure 5741 and the air intake baffle 571. The first intermediate transmission structure 5741 has a lever structure with a fulcrum in the middle. The second intermediate transmission structure 5742 is a resilient, axially moving structure. The elastic member 575 at the first intermediate transmission 5741 is a torsion spring, but may be other elastic members to perform this function. The elastic member 575 at the second intermediate transmission structure 5742 is an elongated coil spring, but may be other elastic members for performing this function. When the transmission mechanism 573 is not acting on the intermediate transmission structure 574, the first intermediate transmission structure 5741 will not act on the second intermediate transmission structure 5742, and the second intermediate transmission structure 5742 will not act on the intake screen 571 either. The downward movement of the other end of the transmission mechanism 573 acts on one end of the first intermediate transmission structure 5741 to overcome the elastic force of the elastic member 575 therein and move downward, so that the other end moves upward, thereby pushing the second intermediate transmission structure 5742 to overcome the elastic force of the elastic member 575 therein and move upward, and finally acts on one end of the air inlet barrier 571 to overcome the elastic force of the elastic member 575 therein and open the air inlet barrier 571, so that the first air duct 54 communicates with the filtering channel 55.

The ventilating flap 572 is a lever structure with a middle pivot, and the elastic member 575 at the ventilating flap 572 keeps the ventilating flap 572 in a closed state when the ventilating flap 572 is not acted by the transmission mechanism 573. The downward movement of the other end of the transmission mechanism 573 acts on the discharge damper 572 and causes it to open the discharge damper 572 against the elastic force of the elastic member 575. Thus, the exhaust duct 56 communicates with the outside of the water tank 50, and exhausts the wind to the outside environment. The air duct structure can be controlled to be opened or closed, so that the air duct structure can be prevented from being polluted by the external environment.

In summary, the automatic cleaning device 100 of the present invention is provided with the first air suction opening 14 and the second air suction opening 15, so as to prevent secondary pollution and accelerate the drying speed of the floor, thereby improving the cleaning capability of the automatic cleaning device 100.

Although the present invention has been described in detail with reference to the preferred embodiments, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the spirit and scope of the present invention.
