The shell is rotatably connected with a rotating pin shaft at the bottom. The rolling brush is detachably connected to the rotating pin shaft. The shell is provided with a driving assembly for driving the rotating pin shaft to rotate. The rotating seat is rotatably connected in the shell. The rotating axis of the rotating seat is parallel to the axis of the rolling brush. The sliding seat is slidably connected to the rotating seat along the axis direction of the rolling brush.

[0008] By adopting the above technical scheme, the driving assembly drives the rotating pin shaft to rotate, and drives the rolling brush to rotate for ground cleaning. The dust suction unit sucks the dust and sundries on the ground into the dust collection unit through the second dust suction port facing the rolling brush. The moving assembly drives the sliding seat to reciprocate on the rotating seat along the rolling brush axis direction, so that the cleaning rake on the sliding seat is in abutment with the upper part of the rolling brush in the rapid rotating process, thereby enabling the cleaning rake to contact the hair and sundries on the rolling brush along the rolling brush axial direction and the circumferential direction, and further enabling the hair and sundries on the rolling brush to be completely removed and left on the cleaning rake. Then, the rotating assembly drives the rotating seat to rotate, thereby changing the position of the cleaning rake, so that the dust suction unit sucks the hair and sundries on the cleaning rake into the dust collection unit through the first dust suction port facing the cleaning brush, and the self-cleaning function of the rolling brush is realized.

[0020] By adopting the above technical scheme, when the cleaning rake is turned to the first dust collection port, the lifting assembly on the rotating seat starts to work, drives the baffle to move away from the first dust collection port in the vertical direction, and opens the first dust collection port, so that the hair and other impurities on the cleaning rake can be easily sucked, and the baffle shields the first dust collection port when the cleaning rake moves away from the first dust collection port, so that only the second dust collection port of the dust collection unit is opened at this time, and the loss of suction force of the dust collection unit is reduced.

[0026] In summary, the present application has at least one of the following beneficial technical effects:

[0027] 1. The moving assembly drives the sliding seat to reciprocate on the rotating seat along the rolling brush axis direction, so that the cleaning rake is in contact with the hair and other sundries on the rolling brush along the rolling brush axis and the circumferential direction, so that the hair and other sundries on the rolling brush can be completely removed and left on the cleaning rake; the rotating assembly drives the rotating seat to rotate, changing the position of the cleaning rake, so that the dust collection unit sucks the hair and other sundries on the cleaning rake into the dust collection unit through the first dust collection port facing the cleaning brush, realizing the self-cleaning function of the rolling brush.

[0029] 3. The first electric push rod is matched with the connecting rod, so that the extension of the first electric push rod can synchronously drive the push rod to move and the rotating seat to rotate. The movement of the push plate causes the hair on the cleaning rake to be removed, and the rotation of the rotating seat causes the cleaning rake to be close to the first dust collection port, so that the hair can be collected by the dust collection unit in time. The structure is simple and achieves two purposes at once, improving the cleaning efficiency of the hair on the cleaning rake. 4. The arrangement of the fixed cylinder, the movable rod and the return spring enables the rotating seat to drive the fixed cylinder and the movable rod to rotate when rotating, thereby synchronously driving the baffle to vertically ascend and descend, so as to realize the opening and closing of the first dust collection port.

DETAILED DESCRIPTION

[0035] The following will be described in detail in combination with the drawings. Figures 1-4 The present application will be further described in detail.

[0036] Embodiment 1

[0037] The embodiment of the present application discloses a cleaning mechanism, referring to Figures 1-3The cleaning mechanism comprises a housing 1, a rolling brush 2, a rotating seat 3, a sliding seat 4, a cleaning rake 5 and a dust suction unit 6. The housing 1 is divided into a bottom shell and an upper shell which is combined on the bottom shell. The bottom shell is integrally formed with fixed bases on the left end of the front and rear sides. Rotating pins 11 are rotatably connected to the fixed bases. The housing 1 is provided with a driving assembly for driving the rotating pins 11 to rotate. The rotating sleeves 111 are threadedly connected to the rotating pins 11. First internal threads are formed in the inner walls of the rotating sleeves 111. First external threads are formed in the two end shafts of the rolling brush 2. When the rolling brush 2 is installed, the rotating sleeves 111 on the two rotating pins 11 are threadedly connected to the first external threads on the two end shafts of the rolling brush 2.

[0038] With reference to Figure 2 The rotating seat 3 is rotatably connected to the bottom shell at the top. The rotating seat 3 is located above the rolling brush 2. The rotating axis direction of the rotating seat 3 is the same as that of the rotating pins 11. A first sliding groove is formed in the bottom of the rotating seat 3 along the rotating axis direction. The sliding seat 4 is slidingly connected in the first sliding groove. The cleaning rake 5 is fixedly arranged on the side of the sliding seat 4 close to the rolling brush 2. The cleaning rake 5 abuts against the upper part of the rolling brush 2. The rotating seat 3 is provided with a moving assembly for driving the sliding seat 4 to reciprocally move. The housing 1 is provided with a rotating assembly for driving the rotating seat 3 to rotate.

[0039] With reference to Figure 3 The dust suction unit 6 is arranged in the housing 1. The dust suction unit 6 specifically comprises an air extractor 61, a dust suction pipe 62 and a dust collecting box 63. A dust suction chamber is formed in the middle of the upper shell. A cover 12 is rotatably connected to the opening at the top of the dust suction chamber. The cover 12 is used for opening and closing the dust suction chamber. The air extractor 61 is fixedly arranged on the cover 12. The air extractor 61 can be a centrifugal fan or an axial flow fan. The dust collecting box 63 is clamped in the dust suction chamber. The air inlet of the air extractor 61 is in communication with the dust collecting box 63. A gas permeable diaphragm 64 is arranged on the air inlet. The top of the dust suction pipe 62 is in communication with the bottom of the dust collecting box 63. A first dust suction port 621 is formed in the side wall of the dust suction pipe 62 and faces the cleaning rake 5. A second dust suction port 622 is formed in the bottom wall of the dust suction pipe 62 and faces the bottom of the rolling brush 2.

[0040] In use, the driving assembly drives the rotating pin shaft 11 to rotate to drive the rolling brush 2 to rotate for ground cleaning. At this time, the air extractor 61 is started to enable the garbage and sundries such as the ash layer cleaned by the rolling brush 2 to enter the dust collecting box 63 through the second dust suction port 622. During the cleaning process of the rolling brush 2, the moving assembly drives the sliding seat 4 to reciprocate on the rotating seat 3 along the axis direction of the rolling brush 2, so that the cleaning rake 5 provided on the sliding seat 4 is in abutment with the upper part of the rolling brush 2 in the rapid rotation process, thereby enabling the cleaning rake 5 to contact the hair and sundries on the rolling brush 2 along the axial and circumferential directions of the rolling brush 2, and further enabling the hair and sundries on the rolling brush 2 to be completely removed and left on the cleaning rake 5. Then, the rotating assembly drives the rotating seat 3 to rotate to change the position of the cleaning rake 5, so that the dust suction unit 6 sucks the hair and sundries on the cleaning rake 5 into the dust collecting box 63 through the first dust suction port 621 facing the cleaning brush, and realizes the self-cleaning function of the rolling brush 2. The sundries and ash layer in the dust collecting box 63 are blocked by the air-permeable diaphragm 64, and the air is discharged through the air outlet of the air extractor 61 to realize the collection of garbage. Compared with the prior art in which the cleaning brush and the entangled hair are in a parallel state and it is difficult to completely remove the hair, the moving assembly drives the sliding seat 4 to reciprocate on the rotating seat 3 along the axis direction of the rolling brush 2 to completely remove the hair and sundries on the rolling brush 2, thereby improving the cleaning effect of the equipment.

[0041] For example, referring to Figures 2-3 The moving assembly includes a first motor 31, a reciprocating screw 32 and a sliding block 33. The first motor 31 is fixedly installed on the rotating seat 3, and a battery module 7 for electrically connecting with the first motor 31 is arranged in the shell 1 to provide power for the first motor 31. The battery module 7 is installed at the right end of the bottom shell to balance the overall mass of the cleaning mechanism. The structure of the first motor 31 is usually a common electric rotating device, which can be replaced by other motors with similar rotating driving functions, such as a stepping motor. The reciprocating screw 32 is coaxially connected to the rotating shaft of the first motor 31, and drives the reciprocating screw 32 to rotate when the first motor 31 rotates. The sliding block 33 is slidably sleeved on the reciprocating screw 32, and the sliding seat 4 is provided with a first through hole, and the sliding block 33 is clamped in the first through hole. Thus, when the reciprocating screw 32 rotates, the sliding block 33 moves reciprocally on the reciprocating screw 32, thereby driving the sliding seat 4 to reciprocate on the rotating seat 3. The cooperation of the reciprocating screw 32 and the sliding block 33 is used to realize the reciprocating movement of the sliding block 33, which is known in the prior art and will not be described here.

[0042] For example, referring to Figure 4The driving assembly comprises a first synchronous wheel 13, a second synchronous wheel 14, a third synchronous wheel 15, a fourth synchronous wheel 16, a first synchronous belt 17 and a second synchronous belt 18. The first synchronous wheel 13 is coaxially connected to the rotating shaft of the first motor 31 and rotates with the first motor 31. The second synchronous wheel 14 is rotationally connected to the bottom shell. The diameter of the second synchronous wheel 14 is smaller than that of the first synchronous wheel 13. The first synchronous belt 17 is arranged around the first synchronous wheel 13 and the second synchronous wheel 14. The rotation of the first synchronous wheel 13 is transmitted to the second synchronous wheel 14 through the first synchronous belt 17. Due to the difference in diameter, the rotation speed is accelerated. The third synchronous wheel 15 is coaxially connected to the second synchronous wheel 14. The diameter of the third synchronous wheel 15 is larger than that of the second synchronous wheel 14. The fourth synchronous wheel 16 is coaxially connected to the rotating pin shaft 11. The diameter of the fourth synchronous wheel 16 is smaller than that of the third synchronous wheel 15. The second synchronous belt 18 is arranged around the third synchronous wheel 15 and the fourth synchronous wheel 16. The rotation of the third synchronous wheel 15 is transmitted to the fourth synchronous wheel 16 through the second synchronous belt 18. The rotation speed is accelerated again. Finally, the rotating pin shaft 11 rotates at a faster speed. The rolling brush 2 realizes the cleaning of the ground. Through the cooperation of synchronous wheels with different diameters, the power of the first motor 31 can be effectively transmitted and accelerated to drive the rotating pin shaft 11 to rotate. The rolling brush 2 obtains a suitable rotation speed, thereby improving the cleaning efficiency. The first synchronous wheel 13, the second synchronous wheel 14, the third synchronous wheel 15 and the fourth synchronous wheel 16 are usually made of wear-resistant engineering plastics or metal materials. They can be replaced by other gears or pulleys with similar transmission functions.

[0043] Further, with reference to Figures 3-4In order to fully remove the hair and other sundries on the cleaning rake 5, the sliding seat 4 is provided with a push plate 41, the push plate 41 is slidably sleeved on the cleaning rake 5, a tension spring 42 is connected between the sliding seat 4 and the push plate 41, the tension spring 42 tends to make the push plate 41 close to the sliding seat 4, and the hair adhered on the cleaning rake 5 can be pushed out to realize cleaning by driving the push plate 41 to slide. In the application, the movement of the push plate 41 is realized synchronously in the process of driving the rotating assembly to rotate the rotating seat 3, and specifically, the rotating assembly includes a first electric push rod 43 and a connecting rod 44, one end of the first electric push rod 43 is rotatably connected with the bottom shell, the other end is rotatably connected with the connecting rod 44, a through hole is formed in the push plate 41 along the sliding direction of the sliding seat 4, and the connecting rod 44 is arranged in the through hole. When the first electric push rod 43 is extended and retracted, the push plate 41 is driven to move through the connecting rod 44, and the cleaning rake 5 is further rotated, so that the rotating seat 3 is rotated, and the cleaning rake 5 is directed to the first dust suction port 621. The first electric push rod 43 continues to be elongated to drive the push plate 41 to move away from the sliding seat 4, so that the push plate 41 pushes out the hair and other sundries scraped off from the self-rolling brush 2 on the cleaning rake 5, the pushed-out hair is sucked into the dust suction unit 6 from the first dust suction port 621, the cleaning of the hair and other sundries is realized, and the accumulation of too much hair on the cleaning rake 5 is avoided to affect the cleaning effect of the rolling brush 2. The first electric push rod 43 is a common linear driving device, which can be replaced by a hydraulic push rod or other devices with similar linear driving function.

[0044] In addition, the connecting rod 44 is provided with a travel switch 45, and the housing 1 is provided with a controller 8, the controller 8 is electrically connected with the travel switch 45 and the first electric push rod 43. When the push plate 41 moves to a certain position and touches the travel switch 45, the travel switch 45 transmits a signal to the controller 8, at this time, the controller 8 sends an instruction to the first electric push rod 43 to drive the first electric push rod 43 to complete an elongation and retraction action, so that the hair and other sundries remaining on the cleaning rake 5 can be periodically cleaned during the rapid rotation of the rolling brush 2, the accumulation of sundries on the cleaning rake 5 is reduced, and the cleaning effect of the rolling brush 2 is improved. The travel switch 45 can be a common mechanical travel switch 45 or a proximity travel switch 45.

[0045] Further, the first suction port 621 of the dust suction pipe 62 is vertically slidably connected with a baffle 9 for shielding the first suction port 621, and the rotating seat 3 is provided with a lifting assembly for driving the baffle 9 away from the first suction port 621 when the cleaning rake 5 is turned to the first suction port 621. The lifting assembly comprises a fixed cylinder 91, a movable rod 92 and a return spring 93. One end of the fixed cylinder 91 is fixedly connected to the rotating seat 3, and the other end is provided with a sliding slot. The movable rod 92 is movably inserted into the sliding slot. One end of the movable rod 92 away from the fixed cylinder 91 is rotatably connected to the baffle 9. The two ends of the return spring 93 are respectively connected to the movable rod 92 and the bottom wall of the sliding slot. When the rotating seat 3 is rotated to make the cleaning rake 5 close to the first suction port 621, the movable rod 92 is rotated upward under the driving of the rotating seat 3. Since one end of the movable rod 92 away from the fixed cylinder 91 is rotatably connected to the baffle 9, the baffle 9 can be synchronously driven to vertically rise, so as to open the first suction port 621. When the rotating assembly drives the rotating seat 3 to rotate away from the first suction port 621, the fixed cylinder 91 is rotated, the return spring 93 pulls the movable rod 92 to retract, and the movable rod 92 is rotated with the fixed cylinder 91 in the retraction process, so that the baffle 9 is lowered to shield the first suction port 621 again. The lifting of the baffle 9 does not need an additional power source, which saves power cost. The fixed cylinder 91 and the movable rod 92 can be made of metal materials to ensure their strength and stability.

[0046] The implementation principle of the embodiment of the application is as follows: when the cleaning mechanism starts to work, the battery module 7 supplies power to the first motor 31, the first motor 31 rotates to drive the reciprocating screw rod 32 to rotate, the sliding block 33 moves reciprocatingly on the reciprocating screw rod 32, and then drives the sliding seat 4 to move reciprocatingly on the rotating seat 3 along the axis direction of the rolling brush 2. At the same time, the rotation of the first motor 31 also drives the first synchronous wheel 13 coaxially connected thereto to rotate, the first synchronous wheel 13 transmits the rotation to the second synchronous wheel 14 through the first synchronous belt 17, and the rotation speed is changed due to the different diameters of the two wheels; the third synchronous wheel 15 rotates with the second synchronous wheel 14 and transmits the rotation to the fourth synchronous wheel 16 through the second synchronous belt 18, and the rotation speed is changed again, finally driving the rotating pin shaft 11 to rotate, so that the rolling brush 2 rotates to clean the ground debris. During the cleaning process of the rolling brush 2, the cleaning rake 5 on the sliding seat 4 abuts against the upper part of the rolling brush 2, and with the reciprocating movement of the sliding seat 4, the cleaning rake 5 contacts the hair and other debris on the rolling brush 2 along the axial and circumferential directions of the rolling brush 2, so that the hair and other debris on the rolling brush 2 can be completely removed and left on the cleaning rake 5. When the push plate 41 moves to a certain position and touches the travel switch 45, the travel switch 45 transmits a signal to the controller 8, and the controller 8 sends an instruction to the first electric push rod 43 to drive the first electric push rod 43 to complete one extension and retraction action. The first electric push rod 43 extends and retracts to drive the push plate 41 to move through the connecting rod 44, so that the hair and other debris adhered to the cleaning rake 5 are pushed out. At the same time, the extension and retraction of the first electric push rod 43 drives the rotating seat 3 to rotate towards the first dust suction port 621, and the movable rod 92 rotates upwards under the drive of the rotating seat 3. Since the movable rod 92 is rotatably connected to the baffle 9 at the end away from the fixed cylinder 91, the baffle 9 can be synchronously driven to rise vertically, so as to open the first dust suction port 621. At this time, the air blower 61 works to generate suction in the dust suction pipe 62 to suck the hair pushed out of the cleaning rake 5 into the collection box for collection, finally completing the full cleaning and collection of the hair on the rolling brush 2, realizing the self-cleaning function of the rolling brush 2. Compared with the prior art, the cleaning brush and the entangled hair are in a parallel state, which is difficult to completely remove the hair. The application can completely remove the hair and other debris on the rolling brush 2 by moving the sliding seat 4 reciprocatingly on the rotating seat 3 along the axis direction of the rolling brush 2, thereby improving the cleaning effect of the device.

[0048] The application also provides a sweeping machine, which comprises the above cleaning mechanism and a traveling mechanism. The traveling mechanism can be of a wheel type or a track type, and is driven by a motor to rotate the wheels or tracks, so that the sweeping machine can move on the ground. The sweeping machine integrates the above cleaning mechanism, and can automatically move on the ground and perform cleaning work. The high-efficiency cleaning function of the cleaning mechanism enables the sweeping machine to more effectively clean dust, hair and other debris on the ground, and avoids the problem of hair entanglement on the rolling brush 2 of the cleaning mechanism, thereby improving the cleaning efficiency and use convenience of the sweeping machine.

[0049] The above are all optional embodiments of the present application, and do not limit the protection scope of the present application, so that: all equivalent changes made according to the structure, shape, principle of the present application should be covered within the protection scope of the present application.
