DETAILED DESCRIPTION

[0055] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0056] It should be noted that in the embodiments of the present application, the orientations or positional relationships such as "upper" and "lower" are based on the orientations or positional relationships shown in the accompanying drawings. It should be understood that these orientation terms 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 cannot be understood as limiting the present application. The present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. In addition, the terms "first", "second", "third", etc. are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0057] In the description of the embodiments of this application, it should be noted that, unless otherwise specified or limited, the term "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of this application can be understood in specific circumstances.

[0058] In the description of this specification, the description with reference to the terms "some embodiments", "exemplarily", etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the embodiments of the present application. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art can combine different embodiments or examples described in this application and features of different embodiments or examples without contradiction.

[0059] In the related art, the interference amount between the long-time used and worn-out rolling brush of the cleaning device and the ground is reduced, resulting in a decrease in cleaning ability, and a new rolling brush needs to be replaced to maintain the cleaning effect of the cleaning device, which is costly in maintenance.

[0060] Therefore, in view of the above, Figures 1-6 The cleaning device 100 can maintain the interference amount between the rolling brush and the ground, prolong the service life of the rolling brush, and reduce the cost of the device. The cleaning device 100 comprises a device main body 10, a rolling brush assembly 20, a floating mechanism 30, a walking wheel assembly 40, and a connecting mechanism 50. The rolling brush assembly 20 is rotatably arranged on the device main body 10. The floating mechanism 30 is arranged on the device main body 10, and the floating mechanism 30 comprises an abutting piece 32 which can be kept in abutment with the rolling brush assembly 20. The connecting mechanism 50 is connected with the walking wheel assembly 40, and the connecting mechanism 50 can move with the abutting piece 32 to enable the walking wheel assembly 40 to move relative to the device main body 10.

[0061] The cleaning device comprises but is not limited to a scrubber, a sweeper, or a scrubbing and sweeping integrated machine. The device main body 10 is used to mount and support other components of the cleaning device 100. The rolling brush assembly 20 can be used to clean or sweep garbage, including but not limited to hair, dust, debris, etc. Exemplarily, the rolling brush assembly 20 comprises a rolling brush 21, and as the diameter of the rolling brush 21 changes, the abutting piece 32 moves, thereby driving the walking wheel assembly 40 to move in the vertical direction. The vertical direction is perpendicular to the surface to be cleaned. For example, after long-time use, the diameter of the rolling brush 21 becomes smaller, the abutting piece 32 moves towards the rolling brush 21, thereby driving the walking wheel assembly 40 to move upwards. The rolling brush 21 is used to clean or sweep dust, debris, hair, and other garbage on the surface to be cleaned. Exemplarily, the rolling brush assembly 20 comprises a driving assembly. Under the driving action of the driving assembly, the rolling brush 21 rolls relative to the ground to collect dust, debris, hair, and other garbage on the ground.

[0062] The walking wheel assembly 40 can be a driving wheel mechanism that provides power for the movement of the device, or a driven wheel mechanism that follows the rotation of the driving wheel, which is not limited in the present application. The walking wheel assembly 40 comprises a walking wheel 41, which can be a driving wheel or a driven wheel. By adjusting the height of the walking wheel 41 relative to the device main body 10, the interference amount between the rolling brush 21 and the ground can be adjusted. Exemplarily, the walking wheel 41 comprises but is not limited to a roller, a track wheel, a Mecanum wheel, etc.

[0063] In the present application, the walking wheel assembly 40 is taken as an example for illustration as a driven wheel. Exemplarily, please refer to Figure 1 and Figure 2The cleaning device 100 includes two driving wheels 80 located at the rear side of the cleaning device 100 in the advancing direction, and the roller brush assembly 20 is located at the front side of the cleaning device 100 in the advancing direction. The two driving wheels 80 and the two walking wheels 41 are arranged in a quadrilateral shape at the bottom of the device body 10. The two walking wheels 41 serve as driven wheels and are located between the roller brush assembly 20 and the driving wheels 80. The walking wheels 41 are arranged close to the roller brush assembly 20, and the interference amount of the roller brush 21 with the ground is adjusted by the two walking wheels 41.

[0064] The cleaning device 100 includes two driving wheels, which are located at the rear side of the cleaning device 100 in the advancing direction, and the roller brush assembly 20 is located at the front side of the cleaning device 100 in the advancing direction. The two driving wheels and one walking wheel 41 are arranged in a triangular shape at the bottom of the device body 10. The one walking wheel 41 serves as a driven wheel and is located between the roller brush assembly 20 and the driving wheels. The walking wheel 41 is arranged close to the roller brush assembly 20, and the interference amount of the roller brush with the ground is adjusted by the one walking wheel 41.

[0065] The connection mechanism 50 is connected to the abutting piece 32 in a manner that can move with the abutting piece 32. For example, referring to Figure 6 One end of the connection mechanism 50 is connected to the walking wheel assembly 40, for example, in a rotating manner, and the other end abuts against the abutting piece 32. When the roller brush 21 is worn out, the abutting piece 32 moves towards the roller brush 21. The connection mechanism 50 remains abutting against the abutting piece 32 under the gravity of the cleaning device, and can move with the abutting piece 32, thereby driving the walking wheel assembly 40 to move upwards relative to the device body 10. In this way, the interference amount of the roller brush 21 with the ground can be maintained.

[0066] In another embodiment not shown, one end of the connection mechanism 50 is connected to the walking wheel assembly 40, and the other end is connected to the abutting piece 32. The connection mechanism 50 can drive the walking wheel assembly 40 to move with the abutting piece 32. When the roller brush 21 is worn out, the abutting piece 32 moves towards the roller brush 21. The walking wheel assembly 40 can move upwards with the abutting piece 32. In this way, the interference amount of the roller brush 21 with the ground can be maintained.

[0067] The cleaning device 100 provided by the embodiments of the present application can maintain the interference amount of the roller brush 21 with the ground when the roller brush 21 is worn out and the diameter is reduced, the abutting piece 32 moves towards the roller brush 21, the connection mechanism 50 can move with the abutting piece 32, thereby driving the walking wheel assembly 40 to move upwards relative to the device body 10. In this way, the interference amount of the roller brush 21 with the ground can be maintained, the use time of the roller brush 21 is prolonged, the service life of the roller brush 21 is improved, and the use and maintenance costs of the cleaning device 100 are reduced.

[0068] In some embodiments, referring to Figure 5 and Figure 6The floating mechanism 30 comprises a tensioning member 31, which is drivingly connected with the abutting member 32 to enable the abutting member 32 to abut against the roller brush assembly 20.

[0069] The two ends of the tensioning member 31 are connected with the device main body 10 and the abutting member 32 respectively, and the tensioning member 31 is in a tensioned state to enable the abutting member 32 to abut against the roller brush assembly 20. Thus, when the roller brush 21 is worn, the abutting member 32 can move towards the roller brush assembly 20 and abut against the roller brush assembly 20 under the action of the tensioning member 31. Exemplarily, the tensioning member 31 can be an elastic member, an electric cylinder or a pneumatic cylinder, etc. The movement of the abutting member 32 can be rotation or translation.

[0070] In some embodiments, referring to Figure 6 The tensioning member 31 is a first elastic member, and the abutting member 32 is rotationally connected with the device main body 10, and the first elastic member is arranged between the device main body 10 and the abutting member 32.

[0071] One end of the abutting member 32 is rotatably mounted on the device main body 10, and the other end abuts against the roller brush assembly 20. Exemplarily, referring to Figure 6 The abutting member 32 comprises a rotating portion 323, and the floating mechanism 30 further comprises a pin shaft 33, the rotating portion 323 is formed with a first insertion hole, the device main body 10 is formed with a second insertion hole, and the pin shaft 33 is arranged in the first insertion hole and the second insertion hole to enable the abutting member 32 to rotate relative to the device main body 10 to abut against the roller brush assembly 20.

[0072] The first elastic member can be a spring. Exemplarily, referring to Figure 6 The first elastic member is a compression spring, and the first elastic member is located on the side of the abutting member 32 away from the roller brush assembly 20, i.e. the first elastic member is located between the abutting member 32 and the roller brush assembly 20, and the first elastic member is compressed by the device main body 10 and the abutting member 32 to have elastic potential energy, and when the roller brush 21 is worn to reduce the diameter, the first elastic member releases the elastic potential energy to drive the abutting member 32 to move towards the roller brush assembly 20.

[0073] In some embodiments not shown, the first elastic member is a tension spring, and the first elastic member is located on the side of the abutting member 32 close to the roller brush assembly 20, i.e. the first elastic member is located between the abutting member 32 and the roller brush assembly 20, and the first elastic member is stretched by the device main body 10 and the abutting member 32 to have elastic potential energy, and when the roller brush 21 is worn to reduce the diameter, the first elastic member releases the elastic potential energy to drive the abutting member 32 to move towards the roller brush assembly 20.

[0074] In this embodiment, the spring is used as the first elastic member, which can reduce the space occupied by the first elastic member, reduce the weight of the device, and reduce the production and maintenance cost of the device.

[0075] In some embodiments, referring to Figure 7 and Figure 8The abutment member 32 includes a floating bracket 321 and a floating scraper 322 . The tensioning member 31 is drivingly connected to the floating bracket 321 . The floating scraper 322 is connected to the floating bracket 321 . The floating scraper 322 abuts against the roller brush assembly 20 .

[0076] The floating scraper bar 322 is mounted on the bottom of the floating bracket 321, near the roller brush assembly 20. One end of the floating bracket 321 is rotatably mounted on the device body 10. The floating scraper bar 322 is used to abut the roller brush assembly 20 and scrape away lint, particles, and other debris from the roller brush 21, thereby improving the cleaning effect of the roller brush 21.

[0077] For example, a receiving groove is formed on the bottom of the abutment member 32 near the side of the roller brush assembly 20, and the floating scraper strip 322 is inserted into the receiving groove. In this way, the floating scraper strip 322 can be easily installed and fixed.

[0078] For example, the floating bracket 321 and the floating scraper 322 are integrally formed, which means that the floating scraper 322 is eliminated and its function is replaced by the floating bracket 321, which directly contacts the roller brush 21. In this way, the structural strength of the abutment member 32 can be improved and the production cost can be reduced.

[0079] Exemplarily, the floating bracket 321 and the floating scraper 322 are manufactured separately, so that the floating bracket 321 and the floating scraper 322 can be made of different materials according to needs.

[0080] Exemplarily, the floating scraper strip 322 is made of a flexible material, so that the wear and tear caused by the floating scraper strip 322 to the roller brush 21 can be reduced.

[0081] In some embodiments, the connection mechanism 50 is a linkage mechanism.

[0082] In this embodiment, by changing the length and arrangement of the connecting rod in the connecting rod mechanism, the connecting mechanism 50 can achieve a predetermined motion trajectory, so that the walking wheel assembly 40 can stably abut against the abutment 32, and then the connecting mechanism 50 can drive the walking wheel assembly 40 to follow the movement of the abutment 32.

[0083] For some examples, see Figure 6 The connecting mechanism 50 includes a first connecting rod 51, a second connecting rod 52 and a connecting portion 53. The end of the first connecting rod 51 away from the second connecting rod 52 is connected to the walking wheel assembly 40, and the end of the second connecting rod 52 away from the first connecting rod 51 abuts against the abutment 32. The other end of the first connecting rod 51 and the other end of the second connecting rod 52 are both connected to the connecting portion 53, and the connecting portion 53 is rotatably connected to the device body 10.

[0084] In this embodiment, by setting the lengths and relative angles of the first connecting rod 51 and the second connecting rod 52 , the second connecting rod 52 abuts against the abutting member 32 , thereby driving the traveling wheel assembly 40 to move upward.

[0085] Exemplarily, the first link 51 and the second link 52 are arranged along a straight line.

[0086] For example, see Figure 6 , the first connecting rod 51 and the second connecting rod 52 form an obtuse angle toward the roller brush assembly 20. In this way, the force applied to the second connecting rod 52 can be improved, and under the same conditions, the friction between the second connecting rod 52 and the abutment 32 can be increased, so that the second connecting rod 52 can stably abut against the abutment 32.

[0087] Exemplarily, the connecting mechanism 50 also includes a first fixed shaft, the adapter 53 is formed with a third socket, the device body 10 is formed with a fourth socket, and the first fixed shaft is passed through the third socket and the fourth socket so that the connecting mechanism 50 can rotate relative to the device body 10.

[0088] Exemplarily, the connecting mechanism 50 also includes a second fixed shaft, the end of the second connecting rod 52 connected to the walking wheel assembly 40 has a fifth socket, the end of the walking wheel assembly 40 connected to the second connecting rod 52 has a sixth socket, and the second fixed shaft is passed through the fifth socket and the sixth socket so that the connecting mechanism 50 can drive the walking wheel assembly 40 to move.

[0089] For example, the first connecting rod 51, the connecting portion 53 and the second connecting rod 52 are integrally formed, thereby increasing the structural strength of the connecting mechanism 50 and facilitating production.

[0090] In some embodiments not shown, the connecting mechanism 50 is a gear transmission mechanism.

[0091] Exemplarily, the gear transmission mechanism includes a rack and a transmission wheel set, and the transmission wheel set is composed of multiple transmission wheels, so that the walking wheel assembly 40 can abut against the abutment member 32 through the multiple transmission wheels. Among them, the transmission wheels can be gears or turbines, and the diameters of the transmission wheels can be the same or different.

[0092] For some examples, see Figure 5 The roller brush assembly 20 includes a roller brush 21, and the walking wheel assembly 40 includes a walking wheel 41; the rotation axis of the connecting mechanism 50 along the horizontal direction, that is, the rotation axis of the adapter portion 53 is located between the rotation axis of the roller brush 21 and the rotation axis of the walking wheel 41.

[0093] In this way, the upward force of the travel wheel assembly 40 can be transmitted to the abutment 32 through the connecting mechanism 50, so that the travel wheel assembly 40 moves upward following the connecting mechanism 50, and the roller brush assembly 20 maintains the interference amount with the ground.

[0094] For some examples, see Figures 3-9 The walking wheel assembly 40 includes a walking wheel 41, a wheel bracket 42 and a wheel axle 43. The wheel bracket 42 has a accommodating cavity 42a and a limiting groove 42b connected to the accommodating cavity 42a. The wheel bracket 42 is connected to the connecting mechanism 50; the walking wheel 41 is sleeved on the wheel axle 43 and is located in the accommodating cavity 42a. The wheel axle 43 is passed through the limiting groove 42b.

[0095] When the roller brush 21 is worn, the abutment 32 moves toward the roller brush assembly 20. Under the action of gravity, the walking wheel 41 moves upward relative to the equipment body 10. Since the wheel axle 43 is arranged in the limiting groove 42b, that is, the wheel axle 43 can drive the wheel bracket 42 to move upward, and then the connecting mechanism 50 rotates relative to the equipment body 10, abutting against the abutment 32, thereby maintaining the interference of the roller brush 21 on the ground.

[0096] For example, see Figure 8 The wheel bracket 42 forms a protective cover with a accommodating cavity 42a, the lower part of the accommodating cavity 42a is open, the walking wheel 41 is located in the accommodating cavity 42a of the protective cover, the protective cover forms a limiting hole 42c, the wheel axle 43 is passed through the limiting hole 42c, and the size of the limiting hole 42c in the up and down direction is larger than the diameter of the wheel axle 43, so that the wheel axle 43 can move in the up and down direction relative to the protective cover.

[0097] For some examples, see Figure 9 The traveling wheel assembly 40 further includes a buffer mechanism 44, which is used to buffer the movement of the wheel shaft 43 in the limiting groove 42b along the up and down directions.

[0098] When the traveling wheel 41 is impacted by an external force, the impact force on the roller brush 21 can be reduced by the buffer mechanism 44 .

[0099] For some examples, see Figure 9 The buffer mechanism 44 includes a pressure block 441, a second elastic member 442 and a guide column 443. One end of the guide column 443 has a limiting cap 4431. The other end of the guide column 443 away from the limiting cap 4431 is connected to the wheel bracket 42. The pressure block 441 can slide along the guide column 443. The second elastic member 442 is sleeved on the guide column 443 and is located between the pressure block 441 and the limiting cap 4431.

[0100] It is understandable that one end of the axle 43 passes through the pressing block 441 to drive the pressing block 441 to move upward, that is, to move toward the limiting cap 4431. The limiting cap 4431 and the pressing block 441 compress the second elastic member 442 to achieve buffering.

[0101] Exemplarily, the limiting cap 4431 of the guide column 443 can be the nut of a screw, that is, the body of the guide column 443 is a cylinder with a threaded hole formed at its top. After the second elastic member 442 is sleeved on the body of the guide column 443, the screw with the nut is screwed into the threaded hole at the top of the body of the guide column 443, and the nut limits the second elastic member 442.

[0102] Exemplarily, the limiting cap 4431 of the guide column 443 can be integrally formed with the guide column, and a threaded hole is formed at the bottom end of the guide column 443. After the second elastic member 442 is sleeved on the guide column 443, the screw is screwed from the wheel bracket 42 into the threaded hole at the bottom end of the guide column 443 to connect the guide column 443 to the wheel bracket 42.

[0103] For example, the pressing block 441 has an arcuate groove formed on the side facing the travel wheel 41. When the wheel axle 43 moves upward, it abuts against the wall of the arcuate groove, driving the pressing block 441 upward and squeezing the second elastic member 442 to achieve cushioning. After the wheel axle 43 moves upward and abuts against the upper end of the limiting hole 42c of the wheel bracket 42, the travel wheel 41, the wheel axle 43, the pressing block 441, the second elastic member 442, the guide post 443, and the wheel bracket 42 all move upward relative to the device body 10.

[0104] Illustratively, a groove is formed on one side of the pressing block 441 facing the second elastic member 442 , and at least a portion of the second elastic member 442 is located in the groove to limit the second elastic member 442 .

[0105] In some embodiments not shown, the buffer mechanism 44 includes a pressing block 441 and a second elastic member 442. The pressing block 441 is pressed on the wheel axle 43 corresponding to the position of the limiting groove 42b; the second elastic member 442 is disposed between the pressing block 441 and the wheel bracket 42.

[0106] When the running wheel 41 and the axle 43 move upward relative to the equipment body 10, the second elastic member 442 is compressed by the pressure block 441 and the wheel bracket 42 to achieve buffering. After the wheel axle 43 moves upward and abuts against the upper end of the wheel bracket 42, such as the protective cover limiting hole 42c, the running wheel 41, the axle 43, the pressure block 441, the second elastic member 442 and the wheel bracket 42 move upward together relative to the equipment body 10.

[0107] It can be understood that the upper end of the wheel bracket 42 extends toward the direction of the second elastic member 442 to form a limiting rod (not shown in the figure), and the second elastic member 442 is located between the limiting rod and the pressure block 441. When the walking wheel 41 and the wheel axle 43 move upward relative to the equipment body 10, the second elastic member 442 is compressed by the pressure block 441 and the limiting rod to achieve buffering.

[0108] In the above embodiment, the buffer mechanism 44 further includes a guide post connected between the pressing block 441 and the wheel bracket 42 , and the second elastic member 442 is sleeved on the guide post.

[0109] The guide post 443 is used to guide and limit the movement of the second elastic member 442 to improve the stability of the second elastic member 442 .

[0110] Exemplarily, the second elastic member 442 is a spring, specifically a compression spring.

[0111] For some examples, see Figure 8 The cleaning device 100 further includes a sealing member 60 and a fixed scraper 70 . The fixed scraper 70 is disposed on the device body 10 . The sealing member 60 is disposed on the fixed scraper 70 and abuts against the abutting member 32 .

[0112] The abutment member 32 and the fixed scraper 70 are arranged in the vertical direction, and the seal 60 is provided on the top of the fixed scraper 70, at one end facing the roller brush assembly 20. The seal 60 can prevent debris and / or cleaning water generated by the roller brush assembly 20 from entering between the fixed scraper 70 and the abutment member 32, thereby protecting the electrical components within the device body 10.

[0113] For some examples, see Figure 10 The seal 60 has a sealing body 61, a lip 62 and a plurality of spaced-apart protrusions 63, the lip 62 and the plurality of protrusions 63 being respectively arranged on both sides of the sealing body 61; the fixed scraper 70 has a plurality of fixing holes corresponding to the plurality of protrusions 63, the protrusions 63 being inserted into the fixing holes so that the seal 60 is fixed to the fixed scraper 70, and the lip 62 abuts against the abutting member 32.

[0114] The raised portion 63 is the fixed end of the seal 60 and is inserted into the fixed hole of the fixed scraper 70. It can improve the fixing effect of the seal 60 and the fixed scraper 70 and facilitate installation and removal. The lip 62 is the free end of the seal 60 and is elastic. The abutment 32 is pressed against the free end of the seal 60 toward the fixed scraper 70. The lip 62 is deformed by pressure, which can improve the sealing performance. When the roller brush 21 is worn, the abutment 32 moves toward the roller brush 21, and the abutment 32 and the fixed scraper 70 produce relative displacement, which increases the pressing effect on the free end of the seal 60 and further improves the sealing effect.

[0115] Exemplarily, the sealing body 61 , the lip portion 62 and the raised portion 63 are integrally formed, which can increase the structural strength of the sealing body 61 and facilitate production and manufacturing.

[0116] Exemplarily, the sealing member 60 may be made of rubber, plastic or synthetic resin.

[0117] For example, see Figure 13 and Figure 14 The fixed scraper 70 includes scraping teeth 71, which are arranged toward the roller brush assembly 20 and can clean hair and other garbage entangled on the roller brush assembly 20.

[0118] For some examples, see Figures 11-14 The cleaning device 100 further includes a water tank. The abutment member 32 has a flow channel 324 and a nozzle 325 communicating with the flow channel. The flow channel 324 is communicated with the water tank. The nozzle 325 faces the roller brush assembly 20 .

[0119] The flow channel 324 and the nozzle 325 are located on both sides of the abutment member 32. The flow channel 324 guides the flow of cleaning water provided by the water tank, and then sprays it toward the roller brush 21 through the nozzle 325. Multiple nozzles 325 can be provided at intervals along the length of the abutment member 32. Specifically, the flow channel 324 and the nozzle 325 can be formed on the floating bracket 321.

[0120] A second aspect of the present invention further provides a cleaning system, comprising a base station and a cleaning device according to any one of the present invention embodiments. After docking with the base station, the cleaning device 100 can discharge dust, debris, hair, sewage, and other garbage into the base station.

[0121] The foregoing description is merely a preferred embodiment of the present application and is not intended to limit the present application. Persons skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
