It should be further noted that, for the convenience of description, only some of the structures related to the present application are shown in the drawings, not all of the structures. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The terms "comprising" and "having," as well as any variations thereof, in this application are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements listed, but may alternatively include other steps or elements not listed, or inherent to such process, method, article, or apparatus.

Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.

Referring to fig. 1, in a preferred embodiment of the present application, a cleaning apparatus 100 is used for cleaning a surface 8 to be cleaned of a target to be cleaned, where the surface 8 to be cleaned may be a floor surface, a wall surface, or a dirty surface of another object, and the application target or application scenario of the cleaning apparatus 100 is not specifically limited in the present application. It should be noted that the cleaning device 100 of the present application has both a suction function and a mopping function, and the suction function and the mopping function can be activated simultaneously, or operated in steps according to actual needs, or operated independently. Wherein the suction function can be a dust suction function and/or a water suction function.

The cleaning device 100 may be a sweeping robot or a sweeping and mopping integrated robot 100, etc. Taking the integrated sweeping and mopping robot 100 as an example, the integrated sweeping and mopping robot 100 in the prior art generally includes a movable body and a cleaning assembly 22 connected to the movable body. When the movable body moves on the flat surface, the cleaning assembly 22 is in interference contact with the surface to be cleaned 8, so that the cleaning efficiency is improved. However, during the actual cleaning process, obstacles such as raised road marks, stones, steps or pits may be present on the surface 8 to be cleaned. When encountering the obstacle, the cleaning assembly 22 can move to the surface of the obstacle according to the friction force of the cleaning assembly 22, so that the movable body is in an inclined state as a whole, at this time, the cleaning assembly 22 cannot be in full contact with the surface of the obstacle, and cannot continuously maintain the interference between the cleaning assembly and the surface to be cleaned 8 on a flat surface, thereby reducing the cleaning effect of the cleaning device 100, and further leading to poor user experience.

In order to solve the above problem, the sweeping and mopping integrated robot 100 in the present application includes a moving mechanism 1 and a cleaning mechanism 2, and the moving mechanism 1 moves to drive the cleaning mechanism 2 to move, so as to clean the surface 8 to be cleaned. Meanwhile, the sweeping and mopping integrated robot 100 further includes a floating mechanism 3.

As the name implies, the floating mechanism 3 is a mechanism that enables one of the cleaning mechanism 2 and the moving mechanism 1 to float relative to the other, and thus can contact the surface to be cleaned 8 through the floating mechanism 3 when the cleaning mechanism 2 encounters an obstacle. In the present embodiment, the sweeping and mopping robot 100 is mainly used for cleaning, and therefore, the cleaning mechanism 2 is described as an example of being moved relative to the moving mechanism 1 by the floating mechanism 3.

Specifically, the moving mechanism 1 includes a first body 11 and a driving assembly 12 for driving the first body 11 to move. The driving assembly 12 includes a walking wheel 121 and a walking motor connected to the walking wheel 121, and the walking motor drives the walking wheel 121 to rotate so as to realize the movement of the first body 11. Wherein, the number of walking wheel 121 is provided with two at least, and the walking motor is provided with at least one.

The number of the walking motors is one, and at the moment, the walking motors can be connected with only one walking wheel 121 and can also be connected with two walking wheels 121 through connecting shafts. The number of the traveling motors is two, and the two traveling motors drive the two traveling wheels 121 respectively. At this moment, the walking motor can control the rotating direction and the rotating angle of the walking wheels 121 according to actual requirements, and flexible turning is realized. The number of the traveling motors may be set according to the actual number of the traveling wheels 121, and is not particularly limited herein.

The cleaning mechanism 2 includes a second body 21 and a cleaning assembly 22 connected to the second body 21. Wherein, cleaning assembly 22 includes driving motor, the clean annex of being connected with driving motor, and driving motor's output shaft is rotatory and then drives the rotation of clean annex. The cleaning accessory comprises a support body and a cleaning body which is arranged on the support body and is used for cleaning the surface 8 to be cleaned, the support body is a brush body, and the cleaning body is brush hair. The cleaning body may be fixedly connected to the supporting body by means of bonding, fastening, or the like, or detachably connected to the supporting body by means of engaging, or the like, which is not limited herein and is determined according to actual conditions.

The driving motor may be disposed at the rear side of the support body with the traveling direction of the sweeping and mopping integrated robot 100 being the front direction (indicated by the arrow a). At this time, the support body is connected with the driving motor through a transmission piece. The transmission member may be a gear transmission or a belt transmission, which is not limited herein and is determined according to the actual situation. The driving motor can also be arranged in the supporting body to be coaxially arranged with the supporting body, at the moment, the output shaft of the driving motor can be directly fixedly connected with the supporting body, and the effect of reducing the whole volume of the cleaning mechanism 2 is achieved.

The floating mechanism 3 is connected to the first body 11 and the second body 21, and the floating of the second body 21 drives the cleaning assembly 22 to float. The floating mechanism 3 comprises at least one connecting rod 31, and two ends of the connecting rod 31 are movably connected with the first main body 11 and the second main body 21 respectively, so as to realize 'floating'. In order to make the second body 21 more stable during the floating process, in the present embodiment, two links 31 are provided. Indeed, in other embodiments, the number of the connecting rods 31 may also be three, four, etc., which is not specifically limited herein, depending on the actual situation.

Referring to fig. 1 and fig. 2, in detail, the first end 311 of the link 31 is rotatably connected to the first body 11, and the second end 312 of the link 31 is slidably connected to the second body 21. The purpose of this is to: when the second body 21 floats relative to the first body 11 through the link 31, the first end 311 of the link 31 rotates relative to the first body 11, and the second end 312 of the link 31 is slidably connected to the second body 21, so that the second end 312 of the link 31 does not rotate but only moves linearly. And in order to guarantee that the cleaning assembly 22 can always contact with the surface 8 to be cleaned, so as to guarantee cleaning efficiency, in this embodiment, the second end 312 of the connecting rod 31 and the sliding fit direction of the second main body 21 are arranged along the traveling direction of the sweeping and dragging integrated robot 100, so that the second main body 21 and the cleaning assembly 22 move along the height direction of the sweeping and dragging integrated robot 100 when floating through the connecting rod 31, thereby guaranteeing that the cleaning assembly 22 can always contact with the surface 8 to be cleaned under the driving of the second main body 21, increasing the magnitude of interference, and further guaranteeing the cleaning effect of the sweeping and dragging integrated robot 100.

Wherein, the first end 311 of the connecting rod 31 is rotatably connected with the first body 11 by means of a rotating shaft.

Preferably, the second end 312 of the link 31 is connected to the second body 21 by the slide assembly 52. The sliding assembly 52 includes a limiting groove 521 and a first sliding block 522 slidably engaged with the limiting groove 521, and the limiting groove 521 extends along the moving direction of the sweeping and mopping integrated robot 100. Wherein, the limit groove 521 is opened on one of the second body 21 and the connecting rod 31, and the first slider 522 is arranged on the other of the second body 21 and the connecting rod 31. In this embodiment, the limit groove 521 is opened on the connecting rod 31, and the first slider 522 is provided on the second body 21.

Moreover, in order to ensure that the interference of the cleaning assembly 22 with the surface to be cleaned 8 is consistent with or close to the interference on the flat surface when the cleaning assembly encounters an obstacle, the sweeping and mopping integrated robot 100 further comprises an elastic mechanism 4. The elastic mechanism 4 connects the first body 11 and the link 31, and is extended or compressed by the movement of the link 31. The elastic means 4 comprises at least one elastic member 41, and the elastic force of the at least one elastic member 41 is smaller than the gravity force of the cleaning means 2. The purpose of this is to: when the cleaning mechanism 2 encounters the pit, the cleaning mechanism 2 sinks under its gravity. At this time, if the elastic force of the elastic member 41 is greater than the gravity of the cleaning mechanism 2, the cleaning assembly 22 may not come into contact with the bottom of the pit, so that cleaning may not be performed, and the cleaning efficiency may be lowered, which is contrary. In the present embodiment, one elastic member 41 is provided in number, and one elastic member 41 is connected to the link 31 provided adjacent thereto. In other embodiments, there may be a plurality of elastic members 41, for example, two elastic members 41 may be connected to the connecting rod 31 disposed adjacent to the two elastic members 41, or two elastic members 41 may be connected to the two connecting rods 31 respectively, which is not limited herein.

The elastic member 41 may be a compression spring or a tension spring, depending on the actual situation. The elastic member 41 has a maximum elongation and a maximum compression. The maximum elongation is: the elastic member 41 cannot be further lengthened after being stretched to the longest length; accordingly, the maximum compression is: the elastic member 41 cannot be further shortened when compressed to an extreme extent.

The elastic member 41 is frequently expanded to the maximum elongation and the maximum compression by the external force, which results in gradual loss of the elastic force of the elastic member 41, thereby shortening the service life of the elastic member 41. Therefore, such problems should be avoided during the operation of the sweeping and mopping integrated robot 100.

Therefore, the sweeping and mopping integrated robot 100 further includes a limiting mechanism 5 for limiting the movement range of the floating mechanism 3 so that the amount of expansion and contraction of the elastic mechanism 4 is between the maximum amount of expansion and the maximum amount of compression. "between" is defined as: the elastic member 41 is not extended or compressed by the maximum amount, so that the elastic force of the elastic member 41 is ensured to extend the life span thereof.

The limiting mechanism 5 includes at least two limiting members 51, and in the height direction of the first main body 11, the at least two limiting members 51 are disposed on the first main body 11 and located at two sides of the floating mechanism 3 respectively. The at least two limiting members 51 may be limiting members or limiting posts, which are not specifically limited herein and are determined according to actual situations. The purpose of providing at least two stoppers 51 is: in the height direction of the first body 11, the upward rotation of the link 31 compresses the elastic member 41, the downward rotation of the link 31 elongates the elastic member 41, and the two directions are matched to ensure that the elastic member 41 is not stretched to the maximum elongation and the maximum compression.

As described above with reference to fig. 1 to fig. 3, the first end 311 of the link 31 is rotatably connected to the first body 11, so that a rotation center 313 is formed at the first end 311 of the link 31, and the rotation center 313 is a connection portion between the link 31 and the rotation shaft. It is noted that the first body 11 has an end surface disposed close to the second body 21, a first linear distance S1 is provided between the stopper and the end surface, a second linear distance S2 is provided between the rotation center 313 and the end surface, a third linear distance S3 is provided between the rotation center 313 and the second end 312 of the link 31, the first linear distance S1 is smaller than the second linear distance S2, and the second linear distance S2 is smaller than the third linear distance S3. Please refer to fig. 5 and fig. 6, the purpose of this arrangement is: the position of the limiting member 51 is located on the rotation track of the connecting rod 31, and ensures that when the sweeping and mopping integrated robot 100 climbs or descends, and the connecting rod 31 rotates upward or downward along with the climbing or descending of the second main body 21 and the cleaning assembly 22, the elastic member 41 does not deform to its maximum extension and maximum compression under the action of the connecting rod 31.

Referring to fig. 1, 3, 4 and 5, the sliding assembly 52 is also a part of the limiting mechanism 5, which actually limits the second body 21 and the cleaning assembly 22 to move only along the height direction of the sweeping and mopping integrated robot 100. Specifically, the first slider 522 has an initial position a and a dead center position B. When the first slider 522 is located at the initial position a, the elastic member 41 is in the original state; at the dead point position B, the elastic member 41 is in an extended or compressed state. When the connecting rod 31 abuts against the limiting mechanism 5, the first sliding block 522 is located between the initial position a and the dead point position B, or the first sliding block 522 is located at the dead point position B. The initial position a is located between the two end sides of the limiting groove 521, and the dead point position B is the two end sides of the limiting groove 521.

Referring to fig. 1, 5 and 6, since the chute assembly moves the second body 21 and the cleaning assembly 22 in the height direction, in order to make the cleaning assembly 22 and the second body 21 move more smoothly, the sweeping and mopping integrated robot 100 further includes a guiding mechanism 6 for guiding the moving direction of the second body 21, and the guiding mechanism 6 is connected to the first body 11 through the connecting body 7. The guide mechanism 6 comprises a guide rail 61 and a second slide block 62 in sliding fit with the guide rail 61, and the guide rail 61 is arranged along the height direction of the sweeping and mopping integrated robot 100; the guide rail 61 is connected to one of the second body 21 and the connecting body 7, and the second slider 62 is connected to the other of the second body 21 and the connecting body 7. In the present embodiment, the guide rail 61 is connected to the connecting body 7, and the second slider 62 is connected to the second body 21. The guide rails 61 may be integrally formed with the connecting body 7, or may be separately formed and then fixedly connected by bonding, welding or fastening. The connection between the second slider 62 and the second body 21 is the same as the connection between the guide rail 61 and the connecting body 7.

In summary, the following steps: by providing the floating mechanism 3, the cleaning assembly 22 connected with the second main body 21 can float relative to the first main body 11 through the floating mechanism 3 when encountering obstacles, and further contact with the surface to be cleaned 8; the elastic mechanism 4 connected with the floating mechanism 3 can stretch and retract when the floating mechanism 3 moves so as to apply elastic force to the cleaning assembly 22 and enable the cleaning assembly to be in contact fit with the surface 8 to be cleaned, and therefore cleaning efficiency is guaranteed; and the arrangement of the limiting mechanism 5 limits the movement range of the floating mechanism 3, and ensures that the deformation of the elastic mechanism 4 can be between the maximum elongation and the maximum compression, thereby prolonging the service life of the elastic mechanism 4 and further improving the cleaning efficiency.

The above is only one specific embodiment of the present application, and any other modifications based on the concept of the present application are considered as the protection scope of the present application.
