[0065] The disclosure below provides many different embodiments or examples for realizing different structures of the utility model. In order to simplify the disclosure of the utility model, the components and settings of specific examples are described below. Of course, they are merely examples, and the purpose is not to limit the utility model. In addition, the utility model may repeat reference numbers and / or reference letters in different examples, and such repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the utility model provides various specific examples of processes and materials, but those of ordinary skill in the art may be aware of the application of other processes and / or the use of other materials.

[0066] This embodiment provides a cleaning device, such as a vacuum cleaner, a mop, etc., which is used for cleaning cleaning surfaces such as the floor.

[0067] Taking a vacuum cleaner as an example, the cleaning device includes a cleaning device body 1, a connector 2, and a dust cup (not shown). The cleaning device body 1 is used to vacuum, scrub, and clean the floor, the dust cup is used to filter and collect debris collected by the cleaning device body 1, and the connector 2 is used to connect the cleaning device body 1 and the dust cup. Figure 1 Only the cleaning device body 1 and the joint 2 are shown, and the dust cup is omitted.

[0068] The cleaning device body 1 includes a suction port (not shown), a roller brush 200 and a mop assembly 400. The roller brush 200 is arranged at the suction port. The cleaning device body 1 also includes a fan (not shown). Under the action of the fan, dust, hair and other debris on the ground are sucked in through the suction port and enter the dust cup through the air duct inside the joint 2. The roller brush 200 cleans the ground and allows debris to enter the suction port more effectively. The mop assembly 400 is used to scrub the ground and mop the floor.

[0069] The cleaning device body 1 is provided with a roller brush 200 and a mop assembly 400, so as to take into account the dual functions of vacuuming and mopping, thereby improving the floor cleaning effect and efficiency of the cleaning device.

[0070] In the prior art, when the cleaning device body 1 moves along the ground for cleaning, the mop assembly 400 cannot be raised or lowered, so the roller brush 200 and the mop assembly 400 are always in contact with the ground. However, when the ground is dirty, sometimes it is not necessary to vacuum and mop at the same time, and since the roller brush 200 and the mop assembly 400 are always running, it will cause energy waste. In addition, when the ground is uneven, the mop assembly 400 cannot be in contact with the ground all the time, which reduces the floor scrubbing effect.

[0071] Based on this, this embodiment improves the cleaning device body 1 by arranging the mop assembly 400 to be able to rise and fall, so that the mop assembly 400 can reliably contact the ground, improve the ground scrubbing effect, and reduce energy consumption while ensuring the ground cleaning effect.

[0072] Figure 2 A bottom view of the cleaning device body 1 is shown. Figure 3 for Figure 2 AA section view, Figure 4 for Figure 3 Enlarged view of part B in the middle. Figure 5 and Figure 6 It is a structural diagram of the interior of the cleaning device body 1.

[0073] In some embodiments, reference Figure 2 The cleaning device body 1 includes a shell 100, a dust suction port is arranged at the bottom of the shell 100, and a roller brush 200 is rotatably arranged at the dust suction port.

[0074] An installation space is formed inside the housing 100. An air duct is arranged in the installation space, and the air duct is communicated with the dust suction port. Meanwhile, the air duct is communicated with the dust cup through the air duct in the joint 2.

[0075] When the cleaning device body 1 vacuums the floor, the fan is started, the roller brush 200 rotates, and the dust, hair and other debris on the floor enter the dust cup through the vacuum port, the air duct and the joint 2.

[0076] Reference Figure 5 The cleaning device body 1 includes a roller brush driving unit 300 , which is disposed in an installation space within the housing 100 and is configured to drive the roller brush 200 to rotate.

[0077] Reference Figure 3 and Figure 4 The cleaning device body 1 includes a mop assembly 400, the mop assembly 400 includes a mop body 410 and a connecting shaft 420, the mop body 410 is set at the first end of the connecting shaft 420, and the opposite second end extends into the installation space in the shell 100, and the mop body 410 is configured to scrub the floor.

[0078] The mop body 410 includes a mop mounting portion 411 and a mop 412. The mop 412 is detachably connected to the mop mounting portion 411 by means of Velcro, buckles, etc. The first end of the connecting shaft 420 is connected to the mop mounting portion 411. The mop 412 is used to scrub the floor. After the mop 412 becomes dirty after being used for a period of time, the mop 412 can be removed from the mop mounting portion 411 for cleaning.

[0079] The mop body 410 can rotate to perform friction scrubbing on the floor, thereby improving the floor scrubbing effect.

[0080] The mop body 410 can be raised and lowered. When the mop body 410 is not needed to scrub the ground, the mop body 410 rises and the mop body 410 is away from the ground. When the mop body 410 is needed to scrub the ground, the mop body 410 descends and the mop body 410 contacts the ground.

[0081] The cleaning device body 1 includes a rotation driving unit 800 , which is disposed in an installation space in the housing 100 and is configured to drive the connecting shaft 420 to rotate, thereby driving the mop body 410 to rotate.

[0082] The cleaning device body 1 includes a lifting drive unit, which is disposed in an installation space within the shell 100 and is configured to drive the connecting shaft 420 to move toward or away from the ground to drive the mop body 410 to rise and fall synchronously.

[0083] The cleaning device body 1 in this embodiment is provided with a lifting function of the mop body 410. The mop body 410 can scrub the floor or not according to the user's needs, thereby meeting the cleaning needs of different floors and saving energy.

[0084] Either or both of the roller brush 200 and the mop assembly 400 clean the floor. That is, according to different floor cleaning needs of users, the roller brush 200 is selected to vacuum the floor, or the mop assembly 400 is selected to scrub the floor, or the roller brush 200 and the mop assembly 400 are selected to vacuum and scrub the floor at the same time, thereby achieving the premise of ensuring the floor cleaning effect, avoiding the opening of unnecessary cleaning components and reducing energy consumption.

[0085] When the floor is uneven due to laying carpets or other reasons, the mop assembly 400 can be raised and lowered to ensure that the mop assembly 400 is always in contact with the floor, thereby ensuring a good floor scrubbing effect.

[0086] When the ground is uneven and the height difference between the high ground and the low ground creates steps, when the cleaning device body 1 moves from the low ground to the high ground, if the mop assembly 400 does not rise or fall, it is easy for the motor to be blocked by the mop assembly 400 due to the obstruction of the steps. However, by rising the mop assembly 400, the mop assembly 400 can move smoothly to the high ground and make reliable contact with the high ground.

[0087] In some embodiments, reference Figure 1 and Figure 2 , along the traveling direction of the cleaning device body 1 during cleaning, the roller brush 200 is arranged in front of the mop assembly 400. The roller brush 200 and the suction port are first used to suck away the dust, hair and other debris on the ground, and then the ground is scrubbed, which helps to improve the cleaning effect of the ground.

[0088] In some embodiments, a plurality of mop bodies 410 are provided, and each mop body 410 is configured with a corresponding connecting shaft 420. The plurality of mop bodies 410 are arranged at intervals along the length direction of the suction port to increase the floor scrubbing area and improve the scrubbing efficiency.

[0089] In this specific embodiment, two mop bodies 410 are provided, which are respectively recorded as a first mop body and a second mop body.

[0090] In some embodiments, the plurality of mop bodies 410 are driven by the same lifting drive unit. In other words, the same lifting drive unit drives the plurality of connecting shafts 420 to rotate simultaneously, thereby achieving synchronous lifting of the plurality of mop bodies 410.

[0091] In some embodiments, reference Fig. 9 The lifting driving part includes a slide part 700, and the slide part 700 is arranged in the installation space in the housing 100. The slide part 700 has a height difference along the height direction of the installation space.

[0092] Reference Figure 4 , Figure 6 as well as Figure 7The lifting driving part includes a rotating seat 600, and the rotating seat 600 is arranged in the installation space in the housing 100. The rotating seat 600 is connected to the second end of the connecting shaft 420. Figures 11 to 14 It is a structural diagram of the rotating seat 600.

[0093] The rotating seat 600 cooperates with the slide part 700, and the rotating seat 600 is configured to rotate and move along the slide part 700. In other words, the rotating seat 600 rotates and moves along the slide part 700. Since the slide part 700 has a height difference, the rotating seat 600 will rise and fall, and the rotating seat 600 drives the connecting shaft 420 to rise and fall synchronously, thereby realizing the rise and fall of the mop body 410.

[0094] The lifting drive unit includes a lifting drive assembly 500 , and the lifting drive assembly 500 is configured to drive the rotating seat 600 to rotate, so that the rotating seat 600 drives the connecting shaft 420 to move in a direction away from or close to the ground.

[0095] In other words, the lifting drive assembly 500 drives the rotating base 600 to rotate, and the lifting movement of the mop body 410 is achieved by the rotational movement of the rotating base 600 .

[0096] In this embodiment, through the cooperation between the slide part 700 and the rotating seat 600, the rotating seat 600 is rotated in the horizontal direction and lifted in the vertical direction at the same time, thereby realizing the lifting and lowering of the mop body 410. The lifting drive part only needs to be able to drive the rotating seat 600 to rotate, so there is no need to set up an additional driving mechanism for driving the rotating seat 600 to lift and lower. The cooperation between the rotating seat 600 and the slide part 700 occupies a small space, which helps to realize the compact structure and miniaturization design of the whole machine.

[0097] In some embodiments, reference Figure 5 The cleaning device body 1 includes a limit switch 550, which is configured to limit the rotation angle of the rotating seat 600, thereby controlling the lifting height of the rotating seat 600, and further realizing the control of the lifting height of the mop assembly 400.

[0098] By limiting the rotation angle of the rotating seat 600, the lifting height of the mop assembly 400 is limited, and the detection mechanism is simple and reliable.

[0099] In some embodiments, the limit switch 550 is disposed near the outer peripheral wall of the rotating base 600 , a limit portion 630 is disposed on the outer peripheral wall of the rotating base 600 , and the limit switch 550 is configured to sense the limit portion 630 to limit the rotation angle of the rotating base 600 .

[0100] The installation of the limit switch 550 fully utilizes the circumferential outer space of the rotating seat 600 to achieve limited space utilization.

[0101] When the rotating base 600 rotates until the limit portion 630 contacts the limit switch 550 , the rotating base 600 rotates to the position, the lifting drive motor 510 stops, and the rotating base 600 stops rotating.

[0102] In some embodiments, the limit switch 550 includes a first limit switch and a second limit switch, and the first limit switch and the second limit switch are arranged at intervals along the circumference of the rotating base 600 .

[0103] Correspondingly, a first limiting portion and a second limiting portion are arranged on the outer peripheral wall of the rotating seat 600 at intervals. The first limiting portion cooperates with the first limit switch, and the second limiting portion cooperates with the second limit switch.

[0104] The provision of two limit switches 550 helps to improve detection reliability.

[0105] In some embodiments, multiple mop bodies 410 are provided, each mop body 410 is configured with a connecting shaft 420 and a rotating seat 600 , the multiple rotating seats 600 are driven by the same driving mechanism, and any one of the multiple rotating seats 600 cooperates with the limit switch 550 .

[0106] In other words, when the cleaning device body 1 is provided with a plurality of mop bodies 410 , any one of the plurality of rotating seats 600 can be selected to cooperate with the limit switch 550 .

[0107] Since the multiple rotating seats 600 are driven by the same driving mechanism, when one of the rotating seats 600 stops rotating, the other rotating seats 600 will also be driven to stop rotating synchronously. Therefore, it is only necessary to set a limit portion 630 on one of the rotating seats 600. The rotating seat 600 cooperates with the limit switch 550, and the other rotating seats 600 do not need to be set with a limit portion 630. Fig.11 The rotating seat 600 shown is provided with a limiting portion 630. Fig.13 The rotating seat 600 shown does not have a limit portion 630. [Rotation drive unit]

[0108] In some embodiments, the plurality of mop bodies 410 are driven by the same rotation driving unit 800. In other words, the same rotation driving unit 800 drives the plurality of connecting shafts 420 to rotate simultaneously, thereby achieving synchronous rotation of the plurality of mop bodies 410.

[0109] In some embodiments, reference Figure 6 The rotation driving unit 800 includes a rotation driving motor 810, a power output end of the rotation driving motor 810 is connected to a screw 820, and the screw 820 is connected to a driven gear set. The driven gear set is configured to drive the connecting shaft 420 to rotate, thereby driving the mop body 410 to rotate.

[0110] In this specific embodiment, the driven gear set includes a first driven gear 831, a second driven gear 832, a third driven gear 833, a fourth driven gear 834 and a fifth driven gear 835. The five driven gears are meshed in sequence. The first driven gear 831 is meshed with the screw 820, the second driven gear 832 drives the first mop body to rotate, and the fifth driven gear 835 drives the second mop body to rotate.

[0111] The second driven gear 832 and the fifth driven gear 835 have the largest diameters, and the third driven gear 833 and the fourth driven gear 834 located therebetween have the smallest diameters, so as to achieve reliable force transmission, and the multiple driven gears are compactly arranged and occupy little space.

[0112] In some embodiments, a second mounting hole (not shown) is provided on the gear, and the connecting shaft 420 passes through the second mounting hole. The gear is configured to drive the connecting shaft 420 to rotate, thereby driving the mop body 410 to rotate.

[0113] In other words, the driven gear 830 connected to the connecting shaft 420 is provided with a second mounting hole, the connecting shaft 420 passes through the second mounting hole, and the driven gear 830 rotates, driving the connecting shaft 420 to rotate synchronously. In this specific embodiment, the second driven gear 832 and the fifth driven gear 835 are respectively provided with second mounting holes.

[0114] [Lifting drive unit]

[0115] In some embodiments, reference Figure 7 The lifting drive assembly 500 includes a lifting drive motor 510, the power output end of the lifting drive motor 510 is connected to the screw rod 520, the screw rod 520 extends along the length direction of the installation space, that is, the screw rod 520 is horizontally arranged, a moving part 530 is arranged on the screw rod 520, and a threaded hole 533 for the screw rod 520 to pass through is arranged on the moving part 530, and the rotating seat 600 is connected to the moving part 530. When the moving part 530 moves along the screw rod 520, it drives the rotating seat 600 to rotate.

[0116] The lifting drive motor 510 is started, driving the screw rod 520 to rotate, and the moving member 530 rotates along the screw rod 520 . The moving member 530 drives the rotating seat 600 to rotate, thereby realizing the lifting of the mop body 410 .

[0117] The rotation direction of the screw rod 520 is controlled by the forward and reverse rotation of the lifting drive motor 510, thereby controlling the movement direction of the moving member 530. For example, when the moving member 530 moves in the first direction, it drives the rotating seat 600 to rotate clockwise, and the rotating seat 600 drives the mop body 410 to move upward. When the moving member 530 moves in the second direction, it drives the rotating seat 600 to rotate counterclockwise, and the rotating seat 600 drives the mop body 410 to move downward. The first direction is opposite to the second direction.

[0118] The lifting drive assembly 500 is arranged horizontally to realize the rotation of the rotating seat 600, and then the rotation of the rotating seat 600 is converted into the lifting of the mop body 410 through the cooperation between the rotating seat 600 and the slide part 700. The lifting drive assembly 500 is arranged horizontally to make full use of the horizontal space in the cleaning device body, and will not cause the height change of the cleaning device body 1, which is conducive to realizing the compact and miniaturized design of the whole machine.

[0119] In some embodiments, the structure of the moving member 530 is as follows: Fig.15 As shown, combined with Figure 7 , a limiting groove 531 is provided on the moving member 530, and the limiting groove 531 extends along the height direction of the installation space, that is, the limiting groove 531 is vertically arranged. Figures 11 to 13 A first extension portion 610 is provided on the rotating seat 600 , and the first extension portion 610 is located in the limiting groove 531 , so as to realize the connection between the rotating seat 600 and the moving member 530 .

[0120] When the rotating seat 600 rotates, the first extension portion 610 rotates in the limiting groove 531. In other words, when the moving member 530 moves along the screw rod 520, the first extension portion 610 rotates in the limiting groove 531, and the moving member 530 pulls the rotating seat 600 to rotate.

[0121] When the rotating seat 600 is lifted or lowered, the first extension portion 610 moves along the height direction of the limiting groove 531. In other words, when the rotating seat 600 rotates, the rotating seat 600 is lifted or lowered along the slideway portion 700, and the first extension portion 610 is lifted or lowered along the limiting groove 531.

[0122] The movable cooperation between the limiting groove 531 and the first extension portion 610 can satisfy both the rotation of the rotating base 600 and the lifting and lowering of the rotating base 600 .

[0123] In some embodiments, a guide structure is provided in the installation space of the moving member 530, and the guide structure is used to guide the movement of the moving member 530, improve the movement stability of the moving member 530, and prevent the moving member 530 from tilting and affecting the movement transmission to the rotating seat 600.

[0124] Reference Figure 7 and Figure 8 A guide rail portion 141 is provided on the mounting surface of the screw rod 520, and the guide rail portion 141 extends along the length direction of the screw rod 520. Fig.15 A slot 532 is provided on the moving member 530 , and the guide rail portion 141 is located in the slot 532 . The moving member 530 moves along the guide rail portion 141 to achieve motion guidance.

[0125] The contact surface between the guide rail portion 141 and the slot 532 is a plane with a certain width, which can effectively prevent the moving member 530 from tilting.

[0126] In some embodiments, reference Fig.10 On the other side opposite to the guide rail portion 141, a limit strip 111 is provided. The limit strip 111 extends along the length direction of the screw rod 520. The limit strip 111 contacts the moving part 530. The contact surface between the two is a plane with a certain width. The limit strip 111 plays a role in limiting and preventing the moving part 530 from tilting.

[0127] In some embodiments, reference Figure 7 Any one of the plurality of rotating seats 600 is connected to the moving member 530 , and the lifting drive assembly 500 further includes a connecting rod 540 , which extends along the length direction of the lead screw 520 , and the connecting rod 540 connects the plurality of rotating seats 600 .

[0128] The multiple rotating seats 600 are connected together by the connecting rod 540 , and the synchronous rotation of the multiple rotating seats 600 can be achieved by the same moving member 530 , thereby achieving the synchronous lifting and lowering of the multiple mop bodies 410 .

[0129] The first extension portion 610 is provided with a mounting hole, which is referred to as the third mounting hole 611. The connecting rod 540 is provided with a vertical section 541, which penetrates the third mounting hole 611. When the rotating seat 600 rotates, the vertical section 541 rotates in the third mounting hole 611. When the moving member 530 drives the rotating seat 600 connected thereto to rotate, the rotating seat 600 drives other rotating seats 600 to rotate synchronously through the connecting rod 540.

[0130] In some embodiments, reference Figure 7 and Fig. 9 The slideway portion 700 is located on the outer peripheral side of the rotating seat 600, and the slideway portion 700 extends along the circumference of the rotating seat 600. Fig.11 A second extension portion 620 is disposed on the rotating seat 600 , and the second extension portion 620 cooperates with the slide portion 700 .

[0131] The second extension part 620 is disposed on the outer peripheral wall of the rotating seat 600 to facilitate the cooperation between the second extension part 620 and the slide part 700. The first extension part 610 is disposed on the outer end side of the second extension part 620 so as not to interfere with the cooperation between the first extension part 610 and the slide part 700.

[0132] The height difference of the slide portion 700 along the vertical direction is the lifting height range of the rotating seat 600 , that is, the lifting height range of the mop body 410 .

[0133] In some embodiments, a plurality of slide sections 700 are provided, and the plurality of slide sections 700 are arranged at intervals along the circumference of the rotating seat 600. Correspondingly, a plurality of second extension sections 620 are also provided, and the plurality of second extension sections 620 correspond one to one to the plurality of slide sections 700. The provision of the plurality of slide sections 700 helps to improve the rotation reliability of the rotating seat 600.

[0134] In this specific embodiment, two slideway portions 700 are provided, and the two slideway portions 700 are arranged at intervals along the circumference of the rotating seat 600. Correspondingly, two second extension portions 620 are provided.

[0135] In some embodiments, reference Fig. 9 The slideway portion 700 includes a first protruding portion 710 and a second protruding portion 720, the first protruding portion 710 and the second protruding portion 720 are arranged opposite to each other in the vertical direction, the first protruding portion 710 includes a first arcuate surface 711, the second protruding portion 720 includes a second arcuate surface 721, and an arcuate slideway 730 is formed between the first arcuate surface 711 and the second arcuate surface 721. The second extension portion 620 extends into the arcuate slideway 730.

[0136] When the rotating seat 600 rotates, the second extension portion 620 moves along the arc-shaped slideway 730 . Since the arc-shaped slideway 730 has a height difference in the vertical direction, the rotating seat 600 can be lifted or lowered.

[0137] In some embodiments, when the rotating seat 600 moves upward along the arc slide 730 , the arc surface below the arc slide 730 contacts the second extension portion 620 ; when the rotating seat 600 moves downward along the arc slide 730 , the arc surface above the arc slide 730 contacts the second extension portion 620 .

[0138] The clearance between the first arc surface 711, the second arc surface 721 and the second extension portion 620 is matched to avoid the clearance being too large or too small. If the clearance is too large, the rotating seat 600 may rotate a certain angle without moving up and down, while if the clearance is too small, rotation interference may occur.

[0139] In some embodiments, a first inserting portion 740 is disposed on either or both of the first arcuate surface 711 and the second arcuate surface 721, and the first inserting portion 740 extends along the arcuate slideway 730. A second inserting portion 680 is correspondingly disposed on the second extension portion 620, and the first inserting portion 740 is slidably connected with the second inserting portion 680. Through the insertion cooperation between the first inserting portion 740 and the second inserting portion 680, when the rotating seat 600 rotates, the first inserting portion 740 and the second inserting portion 680 slide relative to each other, thereby improving the sliding reliability of the second extension portion 620 along the arcuate slideway 730 and serving as a motion guide.

[0140] In this specific embodiment, refer to Figure 8 , the first insertion portion 740 is a groove, referring to Fig.12 The second inserting portion 680 is a protrusion, which is inserted into the groove. When the rotating seat 600 rotates, the protrusion moves along the groove.

[0142] In some embodiments, reference Figure 4 The housing 100 includes an upper housing 110 and a lower housing 120. An installation space is formed between the upper housing 110 and the lower housing 120. A dust suction port is provided on the lower housing 120. A water tank 130 is provided on the top of the upper housing 110. The water tank 130 supplies water to the mop 412 of the mop body 410 through a water pipeline to wet the mop 412 for mopping the floor.

[0143] A water pump 150 is provided in the installation space, see Figure 5 , the water pump 150 provides water circulation power.

[0144] In some embodiments, the cleaning device body 1 includes a mounting frame 140, which is disposed in a space enclosed by the upper shell 110 and the lower shell 120. Figure 5 , Figure 8 1 is a structural diagram of the mounting frame 140. An upper mounting space is formed between the mounting frame 140 and the upper shell 110, and a lower mounting space is formed between the mounting frame 140 and the lower shell 120. The mounting frame 140 serves as a mounting carrier for components such as the slideway 700, the rotating seat 600, the lifting drive unit, the water pump 150, and the limit switch 550, and also serves as a space separator.

[0145] The lifting drive unit and the water pump 150 are arranged in the upper installation space, and the driven gear set is arranged in the lower installation space. The lifting drive unit and the rotating drive unit 800 are arranged in partitions, and the two do not interfere with each other, and the internal layout is compact.

[0146] A limit switch mounting seat 142 is disposed on the mounting frame 140 , and the limit switch 550 is disposed in the limit switch mounting seat 142 .

[0147] In some embodiments, the slide portion 700 is disposed in the upper installation space. Specifically, the first protrusion 710 constituting the slide portion 700 is disposed on the mounting frame 140. Figure 8 The second protrusion 720 is disposed on the inner wall of the upper shell 110, referring to Fig.10 .

[0148] In some embodiments, reference Figure 4 and Figure 8The rotating seat 600 is located in the upper installation space between the mounting frame 140 and the upper shell 110. The mounting frame 140 is provided with a fifth installation hole 143, and the second end of the connecting shaft 420 extends into the upper installation space through the fifth installation hole 143 to facilitate the connection of the rotating seat 600. At the same time, the fifth installation hole 143 also makes way for the lifting of the rotating seat 600.

[0149] In some embodiments, Figure 6 for Figure 5 A structural diagram after omitting the mounting frame 140, the lifting drive motor 510, the rotating drive motor 810, and the driven gear set are arranged on the lower shell 120, and an independent space for installing the driven gear set is enclosed between the mounting frame 140 and the lower shell 120, which plays an axial limiting role on the driven gear set and improves the installation reliability of the driven gear set.

[0150] [Installation of mop assembly]

[0151] In some embodiments, reference Figure 4 The lower shell 120 is provided with a first mounting hole (not shown), and a shaft sleeve 900 is provided in the first mounting hole. The first mounting hole on the lower shell 120, the shaft sleeve 900 and the second mounting hole (not shown) on the driven gear 830 are coaxially arranged, and the second end of the connecting shaft 420 passes through the shaft sleeve 900 and the driven gear 830 and extends into the upper mounting space.

[0152] When the driven gear 830 rotates, the connecting shaft 420 is driven to rotate, thereby realizing the rotation of the mop body 410. When the connecting shaft 420 rotates, the connecting shaft 420 rotates in the shaft sleeve 900.

[0153] When the rotating seat 600 rotates, the rotating seat 600 drives the connecting shaft 420 to rise and fall. At this time, the connecting shaft 420 moves along the axial direction of the shaft sleeve 900, so that the mop body 410 moves in a direction away from the ground.

[0154] In some embodiments, reference Fig.14 The cross-sectional shape of the shaft rod 421 of the connecting shaft 420 is non-circular, and correspondingly, the shape of the second mounting hole on the driven gear 830 is adapted to the cross-sectional shape of the shaft rod 421 .

[0155] By setting the cross-sectional shape of the shaft rod 421 to be non-circular, the connecting shaft 420 can achieve horizontal rotation and axial lifting.

[0156] In some embodiments, a plane 423 is disposed on the peripheral wall of the shaft 421 .

[0157] In some embodiments, reference Fig.14The connecting shaft 420 includes an integrally structured shaft rod 421 and a flange portion 422 , wherein the mop body 410 is disposed at one end of the shaft rod 421 , and the flange portion 422 is disposed at the other end of the shaft rod 421 .

[0158] The rotating seat 600 is provided with a mounting hole, which is recorded as the fourth mounting hole 651. The shaft 421 passes through the fourth mounting hole 651. The top of the rotating seat 600 is provided with a cover 660. Figure 4 The cover body 660 limits the flange portion 422 within the rotating seat 600 .

[0159] During installation, the shaft rod 421 is passed through the rotating seat 600 from top to bottom, the flange portion 422 is abutted against the bottom wall 650 of the rotating seat 600, the shaft rod 421 is passed into place, and then the cover body 660 is fixed to the rotating seat 600 by screws or the like, and the flange portion 422 is limited in the gap between the cover body 660 and the bottom wall 650 of the rotating seat 600. In this way, the connecting shaft 420 and the rotating seat 600 are connected as a whole, and the connecting shaft 420 is driven by the rotating seat 600 to rise and fall synchronously.

[0160] It should be noted that the flange portion 422 is not tightly pressed against the cover body 660, so that when the connecting shaft 420 rotates, the connecting shaft 420 will not drive the rotating seat 600 to rotate synchronously, and similarly, when the rotating seat 600 rotates, it will not drive the connecting shaft 420 to rotate. In other words, the rotation of the connecting shaft 420 is only driven by the driven gear 830, and the rotation of the rotating seat 600 can only realize the lifting and lowering of the connecting shaft 420.

[0161] In some embodiments, reference Fig.11 The rotating seat 600 includes a bottom wall 650 and a circumferential wall 640. The bottom wall 650 is provided with a fourth mounting hole 651. The outer side and the inner side of the bottom wall 650 are provided with gaskets 670 respectively. The upper gasket 670 is located between the flange portion 422 and the bottom wall 650. The lower gasket 670 is located between the bottom wall 650 and the driven gear 830. The gasket 670 plays a role in preventing wear. Figure 4 shown.

[0162] [Roller brush drive unit]

[0163] In some embodiments, reference Figure 6 The roller brush driving unit 300 includes a roller brush driving motor 310, a gear is set at the power output end of the roller brush driving motor 310, another gear is set at the end of the roller brush 200, and a synchronous belt 320 is set between the two gears to drive the roller brush 200 to rotate.

[0164] In some embodiments, the rotating drive motor 810 and the roller brush drive motor 310 are located on the front side of the space inside the shell 100, close to the roller brush 200, and are spaced apart. The rotating drive motor 810 is set on one side, and the roller brush drive motor 310 is set on the other opposite side.

[0165] The lifting drive assembly 500 is arranged at the rear side of the installation space in the housing 100. The rotation drive motor 810, the roller brush drive motor 310 and the lifting drive assembly 500 fully utilize the three corners of the space in the housing 100, and the layout is compact.

[0166] [Working Mode]

[0167] In some embodiments, the cleaning device has a first cleaning mode, in which the roller brush 200 is in contact with the ground to vacuum the ground, and the mop body 410 is away from the ground, so there is no need to scrub the ground.

[0168] In other words, when the floor only needs to be vacuumed and not scrubbed, the cleaning device starts the first cleaning mode, the roller brush 200 contacts the floor, the roller brush 200 rotates under the drive of the roller brush drive unit 300, the mop body 410 rises to lift off the floor under the drive of the lifting drive unit, the lifting drive unit is turned off, and the rotating drive unit 800 is turned off.

[0169] In some embodiments, the cleaning device has a second cleaning mode, in which the roller brush 200 is away from the ground and there is no need to vacuum the ground, and the mop body 410 is in contact with the ground to scrub the ground.

[0170] In other words, when the floor does not need to be vacuumed but needs to be scrubbed, the cleaning device turns on the second cleaning mode, and the mop body 410 moves downward under the drive of the lifting drive unit to contact the floor, and the lowered position of the mop body 410 is lower than the position of the roller brush 200, so that the roller brush 200 can be lifted off the floor. After the mop body 410 is lowered into place, the lifting drive unit is closed, the rotating drive unit 800 is turned on, and the mop body 410 performs friction scrubbing on the floor.

[0171] In some embodiments, the cleaning device has a third cleaning mode, in which both the roller brush 200 and the mop body 410 are in contact with the ground.

[0172] In other words, when the floor needs both vacuuming and scrubbing, the roller brush 200 and the mop body 410 are in contact with the floor at the same time.

[0173] The above three working modes of the cleaning equipment can be selected by users according to the cleaning needs of the floor, providing users with different cleaning modes to ensure the floor cleaning effect while avoiding energy waste.
