In all the examples shown and discussed here, any specific value should be construed as merely exemplary and not as a limitation. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that: like reference numerals and letters denote like items in the following drawings, and thus, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0039] See Figures 1 to 9 As shown, according to an embodiment of the present application, a cleaning device is provided. The cleaning device includes a middle sweeping assembly 1, and the middle sweeping assembly 1 includes a housing 10, a cleaning member 20, and a driving member 30.

[0040] Wherein, an installation groove 101 is formed on the housing 10, the cleaning member 20 is rotatably arranged in the installation groove 101, the driving member 30 is directly connected to the cleaning member 20 to drive the cleaning member 20 to rotate in the installation groove 101, and the rotation axis of the cleaning member 20 is collinear with the axis of the driving end 31 of the driving member 30.

[0041] It is worth mentioning that the existing middle sweeping assembly 1 generally includes a housing 10, a cleaning member 20, a reduction gearbox, and a driving member 30. The cleaning member 20 is rotatably arranged on the housing 10, the driving member 30 is usually connected to the cleaning device, and the reduction gearbox is arranged between the driving member 30 and the cleaning member 20. In the existing middle sweeping assembly 1, due to the setting of the reduction gearbox, a relatively large noise will be generated when the reduction gearbox is working, thereby reducing the user experience.

[0042] Compared with the prior art, in this embodiment, the driving component 30 is directly connected to the cleaning component 20, that is, there is no need for a speed reducer transmission, which can reduce the noise generated by the middle sweeping component 1 to a certain extent; in addition, in this embodiment, the rotation axis of the cleaning component 20 is collinear with the axis of the driving end 31 of the driving component 30, which means that when the cleaning component 20 is directly driven by the driving component 30, the cleaning component 20 will not deflect, thus avoiding the increase in noise caused by the aggravated vibration of the cleaning component 20. On the other hand, since the middle sweeping component 1 of this embodiment does not need to use a speed reducer, the space utilization rate of the middle sweeping component 1 is improved to a certain extent.

[0043] Further, one end of the cleaning component 20 facing away from the driving component 30 is the first end 21, and a supporting portion 60 is provided on the inner wall of the mounting groove 101 opposite to the first end 21. The cleaning component 20 is rotatably sleeved on the supporting portion 60, and the center line of the supporting portion 60, the rotation axis of the cleaning component 20, and the axis of the driving end 31 are all located on the same straight line.

[0044] Specifically, the supporting portion 60 penetrates through the cleaning component 20. The supporting portion 60 is used to provide support for the first end 21 of the cleaning component 20, and the cleaning component 20 is rotatably arranged on the supporting portion 60. In addition, in this embodiment, the center line of the supporting portion 60, the rotation axis of the cleaning component 20, and the axis of the driving end 31 are all located on the same straight line; that is to say, after the driving component 30 drives the cleaning component 20, the first end 21 of the cleaning component 20 will not be affected by the supporting portion 60, resulting in the deflection of the first end 21 of the cleaning component 20, thereby avoiding the generation of more noise at the first end 21 of the cleaning component 20.

[0045] Further, the supporting portion 60 includes a support shaft 61. The support shaft 61 extends a predetermined length in the direction close to the cleaning component 20, and a first groove is formed in the first end 21. The support shaft 61 penetrates through the first groove.

[0046] In this embodiment, the cleaning component 20 can be a rotary brush or a combination of a roller and a mop. The support shaft 61 penetrates through the first groove, and the axis of the support shaft 61 is collinear with the rotation axis of the cleaning component 20. Since the first end 21 of the cleaning component 20 is supported by the support shaft 61, the first end 21 of the cleaning component 20 will not shift under the action of gravity. When the cleaning component 20 rotates, the first end 21 of the cleaning component 20 will not deflect, resulting in large vibrations and noises on the cleaning component 20.

[0047] In this embodiment, since the cleaning component 20 generates a certain amount of vibration when rotating, the vibration is transmitted to the support shaft 61. If the vibration of the support shaft 61 is too large, the support shaft 61 will be separated from the inner wall surface of the mounting groove 101 and a relatively large noise will be generated between the support shaft 61 and the inner wall surface of the mounting groove 101. To solve the above problems, the middle sweeping assembly 1 of this embodiment further includes a first flexible connecting member 40, and the first flexible connecting member 40 is arranged between the support portion 60 and the inner wall surface of the mounting groove 101.

[0048] That is to say, when the support shaft 61 vibrates, since the first flexible connecting member 40 is arranged between the support shaft 61 and the inner wall surface of the mounting groove 101, the vibration of the support shaft 61 is buffered by the first flexible connecting member 40, so that the vibration transmitted to the inner wall surface of the mounting groove 101 is greatly reduced, thereby avoiding excessive vibration of the inner wall surface of the mounting groove 101 and generating noise. On the other hand, since the support shaft 61 and the inner wall surface of the mounting groove 101 do not directly contact, it is prevented that the support shaft 61 vibrates too much, resulting in interference between the support shaft 61 and the inner wall surface of the mounting groove 101 and damage to the inner wall surface of the mounting groove 101 or the support shaft 61.

[0049] Further, a first connecting portion 33 is arranged on the driving seat 32 of the driving component 30, and a second connecting portion 12 is arranged on the outer housing 10; the middle sweeping assembly 1 further includes a fixing member and a second flexible connecting member 50, the second flexible connecting member 50 is arranged between the first connecting portion 33 and the second connecting portion 12, and the fixing member is used to fix the first connecting portion 33, the second flexible connecting member 50 and the second connecting portion 12.

[0050] In this embodiment, the driving component 30 is connected to the second connecting portion 12 on the outer housing 10 through the first connecting portion 33 on the driving seat 32, so that the driving component 30 is fixed on the outer housing 10. When the driving component 30 works, since the driving component 30 itself generates vibration, a relatively large noise may be generated between the first connecting portion 33 and the second connecting portion 12. Therefore, in this embodiment, the second flexible connecting member 50 is arranged between the first connecting portion 33 and the second connecting portion 12. Thanks to the buffering effect of the second flexible connecting member 50, the vibration transmitted from the first connecting portion 33 to the second connecting portion 12 is reduced, thereby avoiding a relatively large noise between the first connecting portion 33 and the second connecting portion 12.

[0051] Further, the first connecting portion 33 includes a connecting block 331, and a first connecting hole 332 is formed in the connecting block 331; the second connecting portion 12 includes a connecting protrusion 121, the connecting protrusion 121 passes through the first connecting hole 332, and a second connecting hole 122 is formed in the middle of the connecting protrusion 121; a third connecting hole 51 is formed through the second flexible connecting member 50, the second flexible connecting member 50 passes through the first connecting hole 332, and the connecting protrusion 121 is inserted into the third connecting hole 51, and a fixing member passes through the third connecting hole 51 and is connected in the second connecting hole 122.

[0052] Specifically, during actual assembly, first align the connecting hole with the connecting protrusion 121, and make the connecting protrusion 121 pass through the first connecting hole 332. Then, pass the second flexible connecting member 50 through the first connecting hole 332 and make the connecting protrusion 121 inserted into the third connecting hole 51. Finally, pass the fixing member through the third connecting hole 51 and make the fixing member connected in the second connecting hole 122, thereby fixing the connecting block 331, the second flexible connecting member 50 and the connecting protrusion 121 together.

[0053] In addition, in some embodiments, an avoidance opening 333 is provided on the outer periphery of the connecting block 331, and the avoidance opening 333 communicates with the first connecting hole 332. When assembling the second flexible connecting member 50, the second flexible connecting member 50 can be inserted into the first connecting hole 332 through the avoidance opening 333. Additionally, an annular groove 52 is provided on the outer periphery of the second flexible connecting member 50. When the second flexible connecting member 50 is located in the first connecting hole 332, the connecting block 331 is clamped in the annular groove 52, thereby improving the connection stability between the second flexible connecting member 50 and the connecting block 331.

[0054] In some embodiments, there are multiple first connecting portions 33, and the multiple first connecting portions 33 are arranged at intervals along the outer periphery of the driving seat 32. There are also multiple second connecting portions 12, and the multiple second connecting portions 12 are arranged at intervals along the circumferential direction of the outer housing 10. There are multiple fixing members and multiple second flexible connecting members 50, and each first connecting portion 33, each second connecting portion 12, each second flexible connecting member 50 and each fixing member are arranged in one-to-one correspondence, thereby improving the connection reliability between the driving component 30 and the outer housing 10. The fixing member includes a bolt.

[0055] Further, the driving end 31 includes a driving shaft 311 and an adapter 312, and the adapter 312 is arranged at one end of the driving shaft 311 close to the cleaning component 20; a second groove adapted to the adapter 312 is formed in the second end 22 of the cleaning component 20 close to the driving component 30, and the adapter 312 is embedded in the second groove.

[0056] It can be understood that the drive shaft 311 is cylindrical. If the drive shaft 311 is directly inserted into the second groove, the frictional force between the drive shaft 311 and the second groove may be too small, resulting in the inability of the drive shaft 311 to drive the cleaning component 20 to rotate when the drive shaft 311 rotates. Therefore, in this embodiment, an adapter 312 is provided at one end of the drive shaft 311 close to the cleaning component 20. The adapter 312 is used to increase the contact frictional force between the adapter 312 and the second groove, so that when the drive shaft 311 rotates, the adapter 312 can drive the cleaning component 20 to rotate. The adapter in this embodiment is a connector, and the connector is fixedly connected to the drive shaft 311 by bolts.

[0057] Furthermore, a protective groove 13 is formed on the outer housing 10, and a part of the drive seat 32 of the drive component 30 is located in the protective groove 13.

[0058] Specifically, after the drive component 30 is installed on the outer housing 10, a part of the drive seat 32 is located in the protective groove 13. The protective groove 13 can improve the waterproof and dustproof capabilities of the drive seat 32, preventing water stains or dust from entering the drive seat 32 when the middle sweeping assembly 1 is cleaning the ground, thereby affecting the drive component 30.

[0059] In some embodiments, a first arc surface is provided on the drive seat 32 located in the protective groove 13, and a second arc surface adapted to the first arc surface is provided on one side of the protective groove 13 close to the drive seat 32. The first arc surface and the second arc surface cooperate to prevent interference between the drive seat 32 and the protective groove 13.

[0060] In some embodiments, as shown in the attached Figure 7 figure, the outer housing 10 includes a shock-absorbing section 11. Shock-absorbing holes are formed in the shock-absorbing section 11, and the second connecting portion 12 is provided on the shock-absorbing section 11.

[0061] Specifically, when the second flexible connecting member 50 transmits the vibration on the drive component 30 to the second connecting portion 12, since the shock-absorbing holes are provided on the shock-absorbing section 11, the shock-absorbing holes weaken the vibration on the outer housing 10, thereby preventing excessive vibration on the outer housing 10 from causing excessive noise. On the other hand, the setting of the shock-absorbing holes can change the stiffness distribution of the outer housing 10 to a certain extent, thereby preventing resonance between the outer housing 10 and the drive component 30. In this embodiment, the first flexible connecting member 40 and the second flexible connecting member 50 can be silicone connecting members, thermoplastic polyurethane connecting members, and polyvinyl chloride connecting members.

[0062] In this embodiment, the drive component 30 includes a brushless motor. Specifically, the existing drive component 30 uses a brushed motor. Due to the continuous mechanical friction between the carbon brush and the commutator, the motor generates relatively large noise during operation. In this embodiment, a brushless motor is used to avoid excessive noise on the motor.

[0063] In addition, the cleaning device in this embodiment includes a main body. The middle sweeping component 1 is arranged at the bottom of the main body, and along the height direction of the main body, the middle sweeping component 1 can reciprocate along the height direction of the main body.

[0064] During actual operation, the middle sweeping component 1 will move downward a certain distance along the height direction of the main body under the action of gravity. When the middle sweeping component 1 comes into contact with the protrusion on the ground, the middle sweeping component 1 is affected by the protrusion, so that the middle sweeping component 1 moves upward a certain distance along the height direction of the main body, that is, the middle sweeping component 1 in this embodiment can float in the height direction of the main body according to different working conditions. At the same time, since the driving component 30 is directly connected to the cleaning component 20 in this embodiment, and the axis of the driving end 31 of the driving component 30 is collinear with the rotation axis of the cleaning component 20, this means that when the cleaning component 20 floats, the driving component 30 also floats accordingly, thereby avoiding the risk of damage to the driving component 30 caused by the driving component 30 not floating when the cleaning component 20 floats.

[0065] In summary, in the middle sweeping component 1 and the cleaning device of this application, the driving component 30 is directly connected to the cleaning component 20, and the axis of the driving end 31 of the driving component 30 is collinear with the rotation axis of the cleaning component 20, thereby avoiding the deflection of the cleaning component 20 during rotation and reducing the noise generated by the cleaning component 20. In addition, a support shaft 61 is provided on the inner wall surface of the installation groove 101. The support shaft 61 penetrates through the first end 21 of the cleaning component 20, and the axis of the support shaft 61, the rotation axis of the cleaning component 20, and the axis of the driving end 31 are collinear, preventing the first end 21 of the cleaning component 20 from deflecting during rotation. In addition, in this application, there is a first flexible connecting member 40 between the support shaft 61 and the outer housing 10, and there is a second flexible connecting member 50 between the second connecting portion 12 of the outer housing 10 and the first connecting portion 33 of the driving seat 32. Through the setting of the flexible connecting member, the generation of large vibrations between the support shaft 61 and the outer housing 10, and between the first connecting portion 33 and the second connecting portion 12 is avoided.
