[0030] Typical embodiments that embody the features and advantages of the present disclosure will be described in detail in the following description. It should be understood that the present disclosure can have various variations in different embodiments without departing from the scope of the present disclosure, and the description and drawings therein are essentially for illustrative purposes rather than for limiting the present disclosure.

[0031] In the following description of different exemplary embodiments of the present disclosure, reference is made to the accompanying drawings, which form a part of this disclosure and in which are shown by way of example different exemplary structures, systems and steps that may implement aspects of the present disclosure. It should be understood that other specific schemes of components, structures, exemplary devices, systems and steps may be used, and structural and functional modifications may be made without departing from the scope of the present disclosure. Moreover, although the terms "above", "between", "within", etc. may be used in this specification to describe different exemplary features and elements of the present disclosure, these terms are used herein for convenience only, such as according to the orientation of the examples in the accompanying drawings. Nothing in this specification should be construed as requiring a specific three-dimensional orientation of the structure to fall within the scope of the present disclosure.

[0032] An embodiment of the present disclosure provides a sweep and drag module, please refer to Figures 1 to 12The sweeping and mopping module includes: a fixed bracket 100; a rotating assembly 110, the rotating assembly 110 is arranged on the fixed bracket 100; a sweeping piece 120, the sweeping piece 120 is arranged on the rotating assembly 110; and a mopping piece 130, the mopping piece 130 is arranged on the rotating assembly 110; wherein the rotating assembly 110 is rotatably arranged on the fixed bracket 100 so that the sweeping piece 120 or the mopping piece 130 is in a working position.

[0033] The sweeping and mopping module of one embodiment of the present disclosure is configured such that the sweeping part 120 and the mopping part 130 are mounted on a rotating assembly 110, and the rotating assembly 110 is rotatably disposed on a fixed bracket 100, so that the sweeping part 120 or the mopping part 130 can be switched between working positions, thereby ensuring that the sweeping part 120 and the mopping part 130 can be used independently.

[0034] It should be noted that the sweeping element 120 and the mopping element 130 are used to clean the surface to be cleaned, such as the floor. When the sweeping element 120 is in contact with the surface to be cleaned and the mopping element 130 is separated from the surface to be cleaned, the sweeping element 120 is in the working position, such as Figure 5 Accordingly, when the sweeping member 120 is separated from the surface to be cleaned, and the mopping member 130 is in contact with the surface to be cleaned, the mopping member 130 is in the working position, as shown. Figure 6 The working position is a position indicating that cleaning can be achieved, that is, the sweeping element 120 or the mopping element 130 of the sweeping and mopping module can clean the surface to be cleaned.

[0035] In one embodiment, the sweeping element 120 is a sweeping roller brush, and the mopping element 130 is a mopping roller brush, and both the sweeping element 120 and the mopping element 130 are rotatably arranged relative to the rotating assembly 110. The sweeping roller brush can be a mechanism for sweeping, such as a brush, and the mopping roller brush can include a mopping component, such as a mop.

[0036] It should be noted that the center lines of the sweeping element 120 and the mopping element 130 may be on the same plane.

[0037] In one embodiment, the rotation of the rotating assembly 110 relative to the fixed bracket 100 can be driven by a driving mechanism in the related art. For example, the driving mechanism includes a telescopic rod connected to the rotating assembly 110, and the extension and retraction of the telescopic rod are used to drive the rotating assembly 110, thereby causing the rotating assembly 110 to rotate relative to the fixed bracket 100. Alternatively, the driving mechanism includes a drive shaft connected to the rotating assembly 110, and the forward and reverse rotation of the drive shaft can drive the rotating assembly 110, thereby causing the rotating assembly 110 to rotate relative to the fixed bracket 100.

[0038] In one embodiment, Figure 2As shown, the rotating assembly 110 has a first accommodating cavity 113 and a second accommodating cavity 114, the sweeping member 120 is arranged in the first accommodating cavity 113, and the mopping member 130 is arranged in the second accommodating cavity 114; wherein at least part of the first accommodating cavity 113 and the second accommodating cavity 114 are independently arranged, so as to prevent the sweeping member 120 and the mopping member 130 from interfering with each other and the like, and ensure normal work of the sweeping member 120 and the mopping member 130.

[0039] Specifically, the first accommodating cavity 113 and the second accommodating cavity 114 are independently arranged, that is, the sweeping member 120 and the mopping member 130 do not affect each other, when the sweeping member 120 sweeps, dust will not enter the second accommodating cavity 114 in large quantities, and the mopping member 130 will not be dirty, and the mopping member 130 itself has a certain amount of water, so the water on the mopping member 130 can also be prevented from entering the first accommodating cavity 113.

[0040] In an embodiment, as shown in Figure 1 The rotating assembly 110 comprises: a floating support 111, which is rotatably arranged on the fixed support 100; and a cover plate 112, which is connected with the floating support 111 and forms the first accommodating cavity 113 and the second accommodating cavity 114 with the floating support 111, so as to not only ensure relative isolation of the sweeping member 120 and the mopping member 130, but also ensure installation stability of the sweeping member 120 and the mopping member 130.

[0041] Specifically, the sweeping member 120 and the mopping member 130 are rotatably arranged on the floating support 111, and the sweeping member 120 and the mopping member 130 are detachably mounted on the floating support 111, and the cover plate 112 is detachably connected with the floating support 111, that is, the sweeping member 120 and the mopping member 130 can be conveniently replaced.

[0042] It should be noted that the center line of the sweeping member 120 and the center line of the mopping member 130 can be parallel.

[0043] In the embodiment, the cover plate 112 is connected with the floating support 111 by clamping, bonding or fasteners, that is, on the basis of ensuring that the cover plate 112 and the floating support 111 are detachable, the connection mode of the cover plate 112 and the floating support 111 is not limited.

[0044] In an embodiment, the sweeping member 120 and the mopping member 130 are both detachably mounted on the floating support 111, and the cover plate 112 and the floating support 111 can also be detachably connected.

[0045] In an embodiment, as shown in Figure 2 and Figure 3As shown, the extension direction of the first accommodating cavity 113 is parallel to the extension direction of the second accommodating cavity 114, and the cover plate 112 is provided with anti-rolling teeth 1121, which are arranged toward the cavity opening of the first accommodating cavity 113, thereby preventing large objects from being rolled into the first accommodating cavity 113 by the sweeping component 120 when the sweeping component 120 is working.

[0046] Specifically, there can be multiple anti-curling teeth 1121, and multiple anti-curling teeth 1121 are arranged at intervals on the cover plate 112, that is, multiple anti-curling teeth 1121 are arranged in sequence along the extension direction of the first accommodating cavity 113, thereby ensuring that large objects will not be rolled into the first accommodating cavity 113 by the sweeping component 120.

[0047] It should be noted that the anti-roll teeth 1121 extend in an arc shape from the cover plate 112 toward the side of the sweeping element 120 , forming a form that substantially covers the sweeping element 120 .

[0048] In one embodiment, Figure 3 As shown, a scraping strip 1122 is provided on the cover member 112 . The scraping strip 1122 is provided on a side of the cover member 112 away from the second accommodating cavity 114 . The scraping strip 1122 can be used to scrape away garbage on the surface to be cleaned.

[0049] In one embodiment, Figure 3 and Figure 4 As shown, the sweeping and mopping module further includes a dust collection channel 160, one end of which is connected to the first accommodating chamber 113, and the other end of which is connected to the fixed bracket 100. The dust collection channel 160 is a flexible member, so that when the sweeping member 120 is in the working position, the dust collection channel 160 is in an open state. When the sweeping member 120 is working, the dust collection channel 160 is used to form an air duct to absorb dust. However, when the mopping member 130 is working, the dust collection channel 160 does not need to work, and the rotation of the rotating assembly 110 causes the dust collection channel 160 to deform. In this case, the dust collection channel 160 does not need to be used as an air duct and can be closed.

[0050] Specifically, the two ends of the dust collection channel 160 are respectively connected to the rotating component 110 and the fixed bracket 100. Therefore, when the rotating component 110 rotates relative to the fixed bracket 100, the sweeping component 120 and the mopping component 130 are switched in the working position. At this time, the dust collection channel 160 as a flexible component is deformed along with the rotating component 110, thereby ensuring that it will not hinder the normal rotation of the rotating component 110.

[0051] In one embodiment, when the mopping member 130 is in the working position, the dust collection channel 160 can be in a closed state. Alternatively, when the mopping member 130 is in the working position, the dust collection channel 160 can also be in an open state.

[0052] In one embodiment, the scraping bar 1122 is arranged adjacent to the dust suction channel 160, that is, the scraping bar 1122 is used to scrape away garbage on the surface to be cleaned, and can also form a better seal between the dust suction channel 160 and the first accommodating chamber 113, ensuring that the dust swept by the sweeping element 120 enters the dust suction channel 160 under the action of suction.

[0053] In one embodiment, the sweeping and mopping module further includes a power component, and the wind generated by the power component can suck the dust swept by the sweeping element 120 into the dust suction channel 160. The power component can be a fan.

[0054] In one embodiment, Figures 1 to 4 As shown, the sweeping and mopping module also includes: a side brush assembly 150, which is arranged on the rotating assembly 110 and / or the fixed bracket 100; wherein, when the sweeping element 120 is in the working position, the side brush assembly 150 is also in the working position, so that the side brush assembly 150 can be used to move dust outside the sweeping element 120 to the area of ​​the sweeping element 120 to ensure the cleaning range.

[0055] Specifically, the side brush assembly 150 is located on one side of the sweeping element 120, that is, the side brush assembly 150 and the sweeping element 120 occupy a first area of ​​the rotating assembly 110, while the mopping element 130 occupies a second area of ​​the rotating assembly 110. By rotating the rotating assembly 110 relative to the fixed bracket 100, the first area is arranged relative to the surface to be cleaned, that is, the side brush assembly 150 and the sweeping element 120 are in the working position and can be used to clean the surface to be cleaned. When the second area is arranged relative to the surface to be cleaned, that is, the mopping element 130 is in the working position, it can be used to mop the surface to be cleaned.

[0056] In one embodiment, the side brush assembly 150 includes a separate driving mechanism, which drives the brush to rotate to achieve cleaning. The driving mechanism includes a motor.

[0057] In one embodiment, Figure 1As shown, the cleaning robot also includes: a side brush plucking mechanism 151, which is rotatably arranged on the rotating component 110, and has a circular ring-shaped component roughly the same as the side brush component 150. The side brush plucking mechanism 151 can rotate away from the rotating component 110, and in this process, the side brush bristles of the side brush component 150 can be plucking along a direction roughly parallel to the axis of the side brush component 150; the purpose of doing this is to prevent the cover member 112 from interfering with the side brush bristles during the closing process after the cover member 112 is opened, thereby pressing the side brush bristles into the cover member 112. When closing the cover member 112, the cover member 112 will timely touch the interference protrusion on the top of the circular ring-shaped component on the side brush plucking mechanism 151, and further press the interference protrusion when closing the cover member 112, thereby driving the side brush plucking mechanism 151 to move along its rotating axis toward the plane where the rotating component 110 is located. In this process, the interference of the side brush plucking mechanism 151 on the plucking of the side brush bristles is further released. When the cover 112 is closed and locked, the side brush plucking mechanism 151 is fully engaged with the rotating assembly 110 , and the cover 112 does not press the side brush bristles.

[0058] The present disclosure also provides an embodiment, in which a tension spring and a ground pressure block assembly 115 installed thereon are provided between the fixed bracket 100 and the floating bracket 111, and the ground pressure block assembly 115 includes a tension spring bracket, one end of the tension spring bracket is fixed to the fixed bracket 100, and the tension spring is inserted into the tension spring bracket from the other end; a tension spring bracket sleeve is provided on the floating bracket 111, and the tension spring can provide a reverse force to the floating bracket 111, so that the cleaning assembly (i.e., the sweeping element 120 and the mopping element 130) installed on the floating bracket 111 can be pressed against the cleaning surface. By providing the ground pressure block assembly 115, the mass of the floating bracket 111 can be significantly reduced without affecting the bonding force between the cleaning assembly and the cleaning surface. In one embodiment, as Figure 1 and Figure 2 As shown, the sweeping and mopping module further includes a position adjustment mechanism 140 , which is connected to the rotating assembly 110 to drive the rotating assembly 110 to rotate.

[0059] Specifically, the position adjustment mechanism 140 is used to achieve rotation of the rotating assembly 110, that is, it can be a driving mechanism in the related art. For example, the position adjustment mechanism 140 includes a telescopic rod, which is connected to the rotating assembly 110. The extension and retraction of the telescopic rod drive the rotating assembly 110, thereby causing the rotating assembly 110 to rotate relative to the fixed bracket 100. Alternatively, the position adjustment mechanism 140 includes a drive shaft, which is connected to the rotating assembly 110. The forward and reverse rotation of the drive shaft can drive the rotating assembly 110, thereby causing the rotating assembly 110 to rotate relative to the fixed bracket 100.

[0060] In one embodiment,Figures 7 to 12 As shown, the position adjustment mechanism 140 includes: a connecting shaft 10; a turntable 20, wherein the two ends of the connecting shaft 10 are respectively connected to the rotating component 110 and the turntable 20; a floating member 30, wherein the floating member 30 is movably arranged on the connecting shaft 10 to be connected to or separated from the turntable 20; a connecting rod shaft 40, wherein the two ends of the connecting rod shaft 40 are respectively connected to the fixed bracket 100 and the turntable 20, and the center line of the connecting shaft 10 does not coincide with the center line of the connecting rod shaft 40; wherein, when the floating member 30 is connected to the turntable 20 and the floating member 30 rotates, the turntable 20 rotates relative to the fixed bracket 100 with the connecting rod shaft 40 as the axis, so that the rotating component 110 rotates relative to the fixed bracket 100.

[0061] Specifically, the position adjustment mechanism 140 can enable the rotating component 110 to rotate relative to the fixed bracket 100 through the connecting shaft 10, the turntable 20, the floating component 30 and the connecting rod shaft 40, and before the rotating component 110 rotates relative to the fixed bracket 100, it is necessary to ensure that the floating component 30 is connected to the turntable 20, that is, the floating component 30 needs to be moved along the connecting shaft 10 to be connected to the turntable 20, so as to form a certain rotation start-up buffer.

[0062] It should be noted that since the floating member 30 and the turntable 20 have two states, connected and separated, when the floating member 30 and the turntable 20 are in the separated state, if it is necessary to drive the rotating assembly 110 to rotate relative to the fixed bracket 100 through the floating member 30, it is necessary to ensure that the floating member 30 and the turntable 20 move from the separated state to the connected state. At this time, the floating member 30 rotates, thereby driving the turntable 20 to rotate relative to the fixed bracket 100 with the connecting rod shaft 40 as the axis, and the floating member 30 and the turntable 20 are both connected to the connecting shaft 10, and the connecting shaft 10 is connected to the rotating assembly 110, so the connecting shaft 10 can drive the rotating assembly 110 to rotate.

[0063] Considering that when the floating member 30 rotates relative to the connecting shaft 10, the floating member 30 will drive the turntable 20 to rotate, and the turntable 20 is connected to the fixed bracket 100 through the connecting rod shaft 40, and the center line of the connecting shaft 10 does not coincide with the center line of the connecting rod shaft 40, therefore, under the driving force of the floating member 30, the turntable 20 rotates relative to the connecting shaft 10 while also rotating relative to the fixed bracket 100 with the connecting rod shaft 40 as the axis, that is, the turntable 20 and the floating member 30 complete self-rotation and revolution at the same time, thereby realizing the rotation of the rotating component 110 relative to the fixed bracket 100.

[0064] It should be noted that the floating member 30 can rotate relative to the connecting shaft 10 . Of course, the floating member 30 can also be circumferentially fixed to the connecting shaft 10 , that is, the floating member 30 can drive the connecting shaft 10 to rotate relative to the rotating assembly 110 .

[0065] In one embodiment, the floating member 30 can be driven by an external driving mechanism to realize the movement relative to the connecting shaft 10. For example, the external driving mechanism can include a telescopic rod connected with the floating member 30, and the extension and retraction of the telescopic rod can realize the movement of the floating member 30 along the connecting shaft 10. When the floating member 30 rotates, the external driving mechanism can rotate synchronously with the floating member 30.

[0066] For the rotation of the floating member 30, a transmission mechanism in the related art can be adopted to ensure that the floating member 30 can realize rotation. For example, a gear transmission mechanism, a chain transmission mechanism or a belt transmission mechanism can be adopted, which is not limited herein, as long as the transmission mechanism can drive the floating member 30 to realize rotation and can rotate relative to the connecting rod shaft 40 simultaneously with the floating member 30.

[0067] In one embodiment, the connecting rod shaft 40 can be directly connected with the rotating disc 20, that is, no adapter mechanism is needed between the connecting rod shaft 40 and the rotating disc 20, and only the center line of the connecting shaft 10 and the center line of the connecting rod shaft 40 need not coincide, so that the rotating disc 20 can rotate relative to the fixed support 100 with the connecting rod shaft 40 as the axis. For example, the connecting rod shaft 40 is fixedly connected with the rotating disc 20, that is, the connecting rod shaft 40 is arranged to deviate from the connecting shaft 10, and the connecting rod shaft 40 is rotatable relative to the fixed support 100, so that when the floating member 30 is connected with the rotating disc 20 and the floating member 30 rotates, the rotating disc 20 drives the connecting rod shaft 40 to rotate relative to the fixed support 100, and at this time, the rotating disc 20 is similar to an eccentric disc. Of course, the connecting rod shaft 40 can be rotatably connected with the rotating disc 20, and the connecting rod shaft 40 is fixedly connected with the fixed support 100.

[0068] In one embodiment, as shown in Figures 7 to 9 , the position adjusting mechanism further includes an adapter 50, two ends of the adapter 50 are connected with the rotating disc 20 and the connecting rod shaft 40 respectively, so that the connecting rod shaft 40 is connected with the rotating disc 20 through the adapter 50, thereby the positional relationship between the connecting rod shaft 40 and the rotating disc 20 is not particularly limited, and the reasonable layout between components is ensured.

[0069] Specifically, in combination with Figure 7 , the adapter 50 can be a connecting plate, and the connecting point of the adapter 50 and the rotating disc 20 is arranged to deviate from the center line of the rotating disc 20, that is, to deviate from the center line of the connecting shaft 10.

[0070] In one embodiment, the connecting rod shaft 40 is fixedly connected with the fixed support 100, and the two ends of the adapter 50 are hingedly connected with the rotating disc 20 and the connecting rod shaft 40 respectively, so that when the rotating disc 20 rotates, the adapter 50 can rotate relative to the rotating disc 20 and the connecting rod shaft 40, thereby preventing the jamming phenomenon.

[0071] Specifically, since the floating member 30 and the turntable 20 rotate and revolve simultaneously, it is necessary to ensure that the adapter 50 does not get stuck, so both ends of the adapter 50 need to be hinged ends.

[0072] In one embodiment, Figure 7 As shown, a first protrusion 21 is provided on the side of the turntable 20 facing the floating member 30, and a second protrusion 31 is provided on the side of the floating member 30 facing the turntable 20, so that when the floating member 30 is connected to the turntable 20, the first protrusion 21 and the second protrusion 31 are in limited contact, thereby ensuring that the floating member 30 can drive the turntable 20 to rotate.

[0073] Specifically, there may be multiple first protrusions 21, with the multiple first protrusions 21 being spaced apart along the circumferential direction of the floating member 30, and there may also be multiple second protrusions 31, with the multiple second protrusions 31 being spaced apart along the circumferential direction of the turntable 20. When the floating member 30 is connected to the turntable 20, the first protrusions 21 and the second protrusions 31 may be staggered to form a relatively fixed relationship. Alternatively, one of the first protrusions 21 and the second protrusions 31 may be formed with a groove, and the other may be inserted into the groove to form a relatively fixed relationship. There is no limitation on the position-limiting connection relationship between the first protrusions 21 and the second protrusions 31, as long as the position-limiting connection can be achieved and the separation can be guaranteed. In this embodiment, multiple first protrusions 21 can form a spiral external gear with the turntable 20, and multiple second protrusions 31 can form a spiral internal gear with the floating member 30, or, multiple first protrusions 21 can form a spiral internal gear with the turntable 20, and multiple second protrusions 31 can form a spiral external gear with the floating member 30, and the spiral external gear is meshed with the spiral internal gear.

[0074] In one embodiment, the floating member 30 is rotatable in both the first direction and the second direction; when the floating member 30 rotates in the first direction, the floating member 30 moves to connect with the turntable 20, and causes the rotating assembly 110 to rotate a preset angle relative to the fixed bracket 100, and the mopping member 130 is in the working position; when the floating member 30 rotates in the second direction, the floating member 30 moves to separate from the turntable 20, and the sweeping member 120 is in the working position.

[0075] Specifically, when the floating member 30 rotates in the first direction, the floating member 30 moves in a direction close to the turntable 20 and moves to be connected with the turntable 20, such as Figure 12As shown, at this time, the floating member 30 continues to rotate in the first direction, thereby driving the turntable 20 to rotate, so that the rotating assembly 110 rotates from the first position to the second position relative to the fixed bracket 100, the mopping member 130 switches from the non-working position to the working position, and the sweeping member 120 switches from the working position to the non-working position. When the floating member 30 rotates in the second direction, the floating member 30 drives the turntable 20 to rotate, and the rotating assembly 110 rotates from the second position to the first position relative to the fixed bracket 100, and the floating member 30 separates from the turntable 20, as shown in FIG. Figure 11 As shown, the sweeping element 120 is switched from the non-working position to the working position, and the mopping element 130 is switched from the working position to the non-working position.

[0076] In one embodiment, Figures 10 to 12 As shown, the position adjustment mechanism 140 also includes: a baffle 70, which is arranged on the fixed bracket 100, and a notch 71 is provided on the baffle 70; wherein, when the floating member 30 rotates along the first direction and causes the rotating assembly 110 to rotate a preset angle relative to the fixed bracket 100, the connecting shaft 10 is clamped in the notch 71; when the floating member 30 rotates along the second direction and causes the connecting shaft 10 to disengage from the notch 71, the floating member 30 moves to separate from the turntable 20. In certain extreme cases, the floating member 30 moves to separate from the turntable 20 and contacts the baffle 70 in a limiting manner.

[0077] Specifically, when the floating member 30 drives the turntable 20 to rotate, the connecting shaft 10 rotates accordingly, and thus enters the notch 71 from the end thereof until it contacts the bottom surface of the notch 71. At this point, the connecting shaft 10 cannot continue to rotate, and thus the relative relationship between the rotating assembly 110 and the fixed bracket 100 is determined, that is, the rotating assembly 110 rotates from the first position to the second position, and the floating member 30 stops rotating in the first direction. When the floating member 30 rotates in the second direction, the connecting shaft 10 may gradually disengage from the notch 71, and during this process, the floating member 30 can move along the connecting shaft 10. After the rotating assembly 110 rotates from the second position to the first position, the floating member 30 continues to rotate in the second direction and disengages from the turntable 20 until the floating member 30 contacts the end surface of the blocking rod 70. At this point, the floating member 30 stops moving along the connecting shaft 10, but can still rotate.

[0078] It should be noted that when the rotating assembly 110 is rotated from the first position to the second position, i.e., the mopping piece 130 is switched from the non-working position to the working position, the position can be determined at this time by the inductor 72, so as to effectively control the floating piece 30 to stop rotating, i.e., the mopping piece 130 is rotated to the working position by the inductor 72. After the rotating assembly 110 is rotated from the second position to the first position, the floating piece 30 has been separated from the rotating disc 20, so that the rotating assembly 110 will not continue to rotate relative to the fixed support 100. The inductor 72 can be a reach switch assembly, for example, an optical coupling switch, or a distance measuring sensor. In some embodiments, a buffer pad 116 is arranged on the rotating assembly 110, and the buffer pad 116 is arranged opposite to the inductor 72, so as to avoid hard contact of the inductor 72 after the inductor 72 is rotated to the position, thereby playing a protection role. When the rotating assembly 110 is rotated from the second position to the first position, i.e., the sweeping piece 120 is switched from the non-working position to the working position, at this time, the sweeping piece 120 can be grounded by relying on the counterweight on the floating support 111 and the tension spring pressure of the grounding block assembly 115, and then start sweeping.

[0079] In one embodiment, as shown in Figure 7 and Figure 8 The position adjusting mechanism 140 includes a first driving assembly 80 and a second driving assembly 60. The first driving assembly 80 is connected with the mopping piece 130, and drives the mopping piece 130 to work when the mopping piece 130 is in the working position. The second driving assembly 60 is connected with the sweeping piece 120, and drives the sweeping piece 120 to work when the sweeping piece 120 is in the working position.

[0080] In one embodiment, as shown in Figure 7 The position adjusting mechanism 140 includes a second driving assembly 60 connected with the floating piece 30 to drive the floating piece 30 to rotate while moving along the connecting rod shaft 40. The second driving assembly 60 is synchronously rotated with the rotating disc 20 relative to the fixed support 100, i.e., the second driving assembly 60 can keep the connection relationship with the floating piece 30, so as to ensure power transmission.

[0081] It should be noted that the floating piece 30 can move relative to the connecting shaft 10 while rotating, i.e., the second driving assembly 60 needs to provide axial direction force and circumferential direction force to the floating piece 30. Here, it is not excluded that the second driving assembly 60 includes two groups of relatively independent driving mechanisms to provide the two directions of force to the floating piece 30.

[0082] In one embodiment, as shown in Figure 9As shown, the floating member 30 includes a first bevel gear segment 32, and the second drive assembly 60 includes: a first transmission gear 61, the first transmission gear 61 includes a second bevel gear segment 611, the second bevel gear segment 611 is engaged with the first bevel gear segment 32 to drive the floating member 30 to rotate; wherein, the floating member 30 can be moved relative to the axial direction of the second bevel gear segment 611.

[0083] Specifically, the second helical gear segment 611 and the first helical gear segment 32 are helical gears that cooperate with each other. Thus, when the second helical gear segment 611 rotates, the second helical gear segment 611 can provide force in two directions to the first helical gear segment 32, ensuring that the first helical gear segment 32 rotates and moves synchronously, thereby connecting the floating member 30 to the turntable 20. After the floating member 30 is connected to the turntable 20, due to the limitations of the turntable 20, the floating member 30 will not continue to move along the connecting shaft 10, but will continue to rotate under the drive of the second helical gear segment 611, thereby driving the turntable 20 to rotate.

[0084] In one embodiment, Figure 8 and Figure 9 As shown, the second drive assembly 60 further includes: a second transmission gear 62 , which is meshed with the first transmission gear 61 ; and a first power source 63 , which is connected to the second transmission gear 62 to drive the second transmission gear 62 to rotate.

[0085] Specifically, the first power source 63 can be a motor, which drives the second transmission gear 62 to rotate, thereby driving the first transmission gear 61 to rotate, thereby transmitting power to the floating member 30 through the first transmission gear 61. In this embodiment, the first power source 63 can be a motor, which can realize forward and reverse rotation.

[0086] In one embodiment, the first power source 63 may be directly connected to the first transmission gear 61 to drive the first transmission gear 61 to rotate. Alternatively, other transmission gears may be provided between the first power source 63 and the second transmission gear 62 to meet the transmission ratio requirements.

[0087] In one embodiment, Figure 8 and Figure 9 As shown, the floating member 30 also includes an output gear segment 33, and the second drive assembly 60 also includes: a first output gear 64, the first output gear 64 is used to connect the sweeping member 120, the output gear segment 33 is engaged with the first output gear 64 to drive the first output gear 64 to rotate; wherein, the floating member 30 can be moved relative to the axial direction of the first output gear 64.

[0088] Specifically, the floating member 30 can be used to drive the turntable 20 to rotate, that is, to realize the rotation of the rotating component 110 relative to the fixed bracket 100, and when the floating member 30 rotates, it can also be used to drive the sweeping member 120 to work, that is, one power member realizes two functions, which can reduce the setting of power components to a certain extent.

[0089] It should be noted that after the floating member 30 is connected to the turntable 20, the rotation of the floating member 30 causes the rotating assembly 110 to rotate relative to the fixed bracket 100. Therefore, after the floating member 30 is connected to the turntable 20, the rotation of the floating member 30 can also drive the sweeping member 120 to operate. After the floating member 30 is separated from the turntable 20, the rotation of the floating member 30 can also drive the sweeping member 120 to operate. In other words, the floating member 30 can rotate in two directions.

[0090] It should be noted that since the floating member 30 can move relative to the connecting shaft 10, the floating member 30 can move relative to the first transmission gear 61 and the first output gear 64 that are meshed with it, but the distance of movement has a fixed value, thereby ensuring that the floating member 30 is in a state of constant meshing with the first transmission gear 61, and the floating member 30 is also in a state of constant meshing with the first output gear 64.

[0091] In one embodiment, the floating member 30 includes a first helical gear segment 32 and an output gear segment 33. The second drive assembly 60 includes a first transmission gear 61 including a second helical gear segment 611 that meshes with the first helical gear segment 32 to drive the floating member 30 to rotate; and a first output gear 64 that is connected to the sweeping member 120 and meshes with the output gear segment 33 to drive the first output gear 64 to rotate. The floating member 30 is movably disposed along both the second helical gear segment 611 and the first output gear 64. The floating member 30 drives the rotating assembly 110 to rotate relative to the fixed bracket 100 via the turntable 20, thereby switching between the sweeping member 120 and the mopping member 130 in the working position. When the sweeping member 120 is in the working position, the floating member 30 can also drive the sweeping member 120 to operate via the first output gear 64.

[0092] In one embodiment, when the floating member 30 rotates along the second direction, the floating member 30 drives the sweeping member 120 to work, and the position adjustment mechanism 140 also includes: a first drive component 80, the first drive component 80 is connected to the mopping member 130 to drive the mopping member 130 to work, that is, after the mopping member 130 is switched to the working position, the first drive component 80 can drive the mopping member 130 to work.

[0093] In one embodiment, Figure 10As shown, the position adjustment mechanism 140 also includes: a shell member 90, the shell member 90 is connected to the rotating component 110, the connecting shaft 10 is connected to the shell member 90, so that the connecting shaft 10 is connected to the rotating component 110 through the shell member 90, and the first drive component 80 is arranged on the shell member 90; wherein, after the connecting shaft 10 is clamped in the notch 71, the floating member 30 stops rotating, the first drive component 80 drives the mopping member 130 to work, and after the floating member 30 is limitedly contacted with the barrier rod 70, the floating member 30 can rotate in the second direction.

[0094] Specifically, when the floating member 30 rotates in the first direction, it drives the rotating assembly 110 to rotate relative to the fixed bracket 100, i.e., the rotating assembly 110 moves from the first position to the second position. When the floating member 30 rotates in the second direction, after the floating member 30 drives the rotating assembly 110 to move from the second position to the first position, the floating member 30 primarily drives the sweeping member 120 to operate. In this embodiment, when the rotating assembly 110 is in the first position, the sweeping member 120 is in the operating position, i.e., rotation of the floating member 30 in the second direction enables the sweeping member 120 to operate. When the rotating assembly 110 is in the second position, the mopping member 130 is in the operating position, and the mopping member 130 is driven to operate by the first drive assembly 80.

[0095] In one embodiment, the position adjustment mechanism includes a first drive assembly 80 and a second drive assembly 60. The second drive assembly 60 enables the rotation of the rotating assembly 110 relative to the fixed bracket 100 and can be used to drive the sweeping element 120. The first drive assembly 80 is used to drive the mopping element 130. Both the first drive assembly 80 and the second drive assembly 60 are disposed on the housing 90.

[0096] Specific, combined Figures 7 to 9 The first transmission gear 61 is composed of a second bevel gear segment 611 and a transmission gear segment 612, and the floating member 30 is composed of a first bevel gear segment 32 and an output gear segment 33. The second transmission gear 62 is engaged with the transmission gear segment 612 to realize the rotation of the first transmission gear 61, and the second bevel gear segment 611 is engaged with the first bevel gear segment 32 to drive the movement and rotation of the floating member 30. The output gear segment 33 is engaged with the first output gear 64, thereby driving the sweeping member 120 to work through the first output gear 64.

[0097] It should be noted that multiple output gears may be included between the first output gear 64 and the sweeping element 120 to meet the transmission ratio requirements. In this embodiment, the first output gear 64 meshes with the second output gear 65, the second output gear 65 meshes with the third output gear 66, and the third output gear 66 meshes with the fourth output gear 67. The fourth output gear 67 is connected to the sweeping element 120, thereby driving the sweeping element 120 to rotate.

[0098] In one embodiment, the first drive assembly 80 includes a second power source 85, which is drivably connected to the first gear 81, thereby driving the first gear 81 to rotate. The first gear 81 can be used to drive the mopping member 130, and multiple gears can be provided between the first gear 81 and the mopping member 130 to meet the transmission ratio. In this embodiment, the first gear 81 meshes with the second gear 82, the second gear 82 meshes with the third gear 83, the third gear 83 meshes with the fourth gear 84, and the fourth gear 84 is connected to the mopping member 130, thereby driving the mopping member 130 to rotate. The second power source 85 can be a motor. In this embodiment, the second power source 85 can be an electric motor that realizes forward and reverse rotation.

[0102] In one embodiment, the sweeping element 120 and the mopping element 130 can be in the working position at the same time, that is, sweeping and mopping are performed at the same time.

[0103] In some embodiments, the sweeping element 120 and the mopping element 130 can rotate synchronously, that is, the sweeping element 120 and the mopping element 130 can be driven to rotate simultaneously by a driving mechanism. For example, the synchronous driving of the sweeping element 120 and the mopping element 130 can be achieved by a gear transmission set.

[0104] In some embodiments, the sweeping element 120 and the mopping element 130 can be driven by two independent driving mechanisms to achieve independent rotation. For example, the two independent first driving assemblies 80 in the sweeping and mopping module can be used to drive the sweeping element 120 and the mopping element 130 to rotate respectively.

[0105] In another embodiment, the rotating assembly 110 is rotatably disposed on the fixed bracket 100 so that the sweeping element 120 or the mopping element 130 is in the working position, that is, the sweeping element 120 and the mopping element 130 cannot be in the working position at the same time.
