The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure.

[0025] In the related art, the driving motor of the cleaning equipment uses a combination of a motor and a reduction gearbox. The motor is connected to the reduction gearbox, and the motor outputs power to the reduction gearbox. The reduction gearbox and other transmission devices transmit the power output by the motor to the corresponding moving parts such as the cleaning mop and driving wheels.

[0026] However, the reduction box is large in size, which will occupy more internal installation space, and the reduction box has more internal moving parts, and the reduction box will make a lot of noise during the operation of the cleaning equipment.

[0027] In order to solve the above technical problems, according to an embodiment of the present disclosure, a cleaning device is provided, which includes: a main body; a fixing member, which is fixed to the main body; a driving member, which includes a rotating part and a fixed shaft, and the fixed shaft is fixed to the main body through the fixing member, and the rotating part is rotatably connected to the fixed shaft, and the rotating part rotates around the fixed shaft as the rotating axis; a cleaning component, and the rotating part is fixedly connected to the cleaning component; wherein the fixing member is used to limit the fixed shaft from rotating relative to the main body.

[0028] The present invention is directly connected to the cleaning component through a rotating part, and the fixing part fixes the fixed shaft of the driving part to the main machine, restricting the driving part from rotating relative to the main machine, thereby allowing the rotating part to rotate relative to the main machine, so that the rotating part can directly drive the cleaning component and output a larger torque in a smaller space, thereby saving a reduction box and other transmission components, providing a larger installation space for the cleaning equipment, and reducing the operating noise of the cleaning equipment.

[0029] It is understandable that the cleaning equipment involved in the present disclosure may be a cleaning equipment with a dust box such as a sweeper, a scrubber, a mop, a sweeper and a mop-in-one. In the following description, a sweeper is used as an example for explanation, and it should be understood that the embodiments of the present disclosure do not limit the specific equipment form of the cleaning equipment.

[0030] Figure 1 The figure is a schematic structural diagram of a cleaning device with part of the main body structure removed according to an exemplary embodiment. Figure 2 is an exploded view of a cleaning device according to an exemplary embodiment. Figure 3 The figure is a schematic cross-sectional structure diagram of a cleaning device with part of the main body structure removed according to an exemplary embodiment. Figure 4 The figure is a schematic cross-sectional structure diagram of a cleaning device with part of the main body structure removed according to an exemplary embodiment.

[0031] In some embodiments, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the cleaning device includes: a main body 1, a fixing member 2, a driving member 3 and a cleaning component 4.

[0032] The host 1 may be a part of the cleaning device, providing installation space and a fixed position for other structures of the cleaning device. Exemplarily, the host 1 may include a housing of the cleaning device.

[0033] The driving member 3 may be a component that can output power. The driving member 3 may provide power for other moving parts in the cleaning device, thereby driving the moving parts to move and work normally.

[0034] The driving member 3 may include a rotating portion 34 and a fixed shaft 33 , and the rotating portion 34 may be rotatably connected to the fixed shaft 33 .

[0035] When the driving member 3 is running, the rotating portion 34 can rotate around the fixed shaft 33 with the fixed shaft 33 as the rotating axis, thereby driving other structures connected to the driving member 3 .

[0036] Cleaning component 4, cleaning component 4 can be a functional component in the cleaning equipment that completes the cleaning operation through its own movement. The rotating part 34 can be fixedly connected to the cleaning component 4, so that when the rotating part 34 rotates around the fixed axis 33, it can drive the cleaning component 4 to rotate around the fixed axis 33, thereby providing the necessary power for the cleaning component 4, so that the cleaning component 4 can complete the cleaning operation normally.

[0037] The fixing member 2 can be fixedly arranged on the main machine 1, and the fixing shaft 33 can be fixed to the main machine 1 through the fixing member 2. The fixing member 2 can limit the rotation of the fixing shaft 33 relative to the main machine 1 through the fixing effect, so that the fixing shaft 33 does not rotate relative to the main machine 1, and then the rotating part 34 rotating relative to the fixing shaft 33 can rotate relative to the main machine 1, which can make the cleaning component 4 connected to the rotating part 34 rotate relative to the main machine 1, so as to complete the cleaning operation.

[0038] Furthermore, since the size of the rotating portion 34 in the radial direction of the rotating shaft is larger than the size of the fixed shaft 33 in the radial direction of the rotating shaft, the rotating portion 34 can output a larger torque without a reduction gearbox.

[0039] The present invention directly connects the cleaning assembly 4 via the rotating part 34, and the fixing part 2 fixes the fixing shaft 33 of the driving member 3 to the main body 1, restricting the driving member 3 from rotating relative to the main body 1, thereby allowing the rotating part 34 to rotate relative to the main body 1. This enables the rotating part 34 to directly drive the cleaning assembly 4 and output a larger torque in a smaller space, thereby saving a reduction gearbox and other transmission components, providing a larger installation space for the cleaning device, and reducing the operating noise of the cleaning device.

[0040] In some embodiments, the driving member 3 may be a motor.

[0041] The rotating part 34 may include a rotor and a stator, the fixed shaft 33 may be a shaft connected to the rotor, and the wires arranged on the rotor and the stator may be connected to the outside of the driving member 3 through the inside of the fixed shaft 33 and connected to the host 1, so that the host 1 can supply power to the driving member 3.

[0042] Since the fixed shaft 33 is fixedly connected to the main machine 1 through the fixing member 2, the fixed shaft 33 will not rotate relative to the main machine 1, so that the rotating part 34 provided with the rotor and the stator can rotate relative to the main machine 1. This allows the cleaning component 4 connected to the rotating part 34 to rotate relative to the main machine 1, so that the cleaning component 4 can complete the cleaning operation through the rotational motion.

[0043] Furthermore, since the size of the rotating part 34 provided with the stator and the rotor in the radial direction of the rotating shaft is larger than the size of the fixed shaft 33 in the radial direction of the rotating shaft, the rotating part 34 can output a larger torque without a reduction gearbox.

[0044] The present invention directly connects the rotating part 34 provided with a rotor and a stator to the cleaning assembly 4, and fixes the fixed shaft 33 of the driving member 3 to the main machine 1 through the fixing member 2, restricting the driving member 3 from rotating relative to the main machine 1, thereby allowing the rotating part 34 to rotate relative to the main machine 1. This enables the rotating part 34 to directly drive the cleaning assembly 4 and output a larger torque in a smaller space, thereby saving a reduction box and other transmission components, providing a larger installation space for the cleaning device, and reducing the operating noise of the cleaning device.

[0045] In some embodiments, Figure 2 As shown, the fixing member 2 may include a clamping portion 21, and the host 1 may be provided with a first through hole, and the first through hole may include a hole wall. The fixed shaft 33 may be inserted into the first through hole, and the clamping portion 21 may be clamped between the fixed shaft 33 and the hole wall. By clamping the clamping portion 21 between the fixed shaft 33 and the hole wall, the pressure between the fixed shaft 33 and the first through hole of the host 1 can be increased, so that an interference connection is formed between the fixed shaft 33, the clamping portion 21 and the host 1, so that the fixing member 2 can strengthen the fixed connection effect between the fixed shaft 33 and the host 1, and the fixing member 2 can limit the rotation between the fixed shaft 33 and the host 1 through the friction between the fixing member 2, the fixed shaft 33 and the host 1, so that the fixed shaft 33 will not rotate relative to the host 1, and then the rotating portion 34 rotating relative to the fixed shaft 33 can rotate relative to the host 1, which can make the cleaning component 4 connected to the rotating portion 34 rotate relative to the host 1, so that the cleaning component 4 can complete the cleaning operation through the rotational motion.

[0046] Furthermore, since the size of the rotating portion 34 in the radial direction of the rotating shaft is larger than the size of the fixed shaft 33 in the radial direction of the rotating shaft, the rotating portion 34 can output a larger torque without a reduction gearbox.

[0047] The present invention directly connects the cleaning assembly 4 via the rotating part 34, and fixes the fixed shaft 33 of the driving member 3 to the main body 1 via the clamping part 21 of the fixing member 2, and restricts the driving member 3 from rotating relative to the main body 1, so that the rotating part 34 rotates relative to the main body 1. This enables the rotating part 34 to directly drive the cleaning assembly 4 and output a larger torque in a smaller space, thereby saving a reduction box and other transmission components, providing a larger installation space for the cleaning device, and reducing the operating noise of the cleaning device.

[0048] In some embodiments, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the cleaning device may include a lifting component 5, and the lifting component 5 may be arranged on the host 1. The lifting component 5 may enable other components connected to the lifting component 5 to move relative to the host 1.

[0049] The lifting component 5 can be fixedly connected to the fixing component 2 and the main unit 1, and through the connection relationship between the fixing component 2, the driving component 3 and the cleaning component 4, the fixing component 2, the driving component 3 and the cleaning component 4 are driven to move relative to the main unit 1, so that the lifting component 5 can control the position of the cleaning component 4 relative to the main unit 1 by controlling the movement of the cleaning component 4, and then the cleaning component 4 can match different working states of the cleaning equipment by changing its position relative to the main unit 1.

[0050] Exemplarily, the lifting assembly 5 can move the cleaning assembly 4 in a direction away from the main body 1 , so that the cleaning assembly 4 can contact the cleaning target.

[0051] The lifting assembly 5 can also move the cleaning assembly 4 toward the main body 1, thereby reducing the probability that the cleaning assembly 4 is contaminated by touching objects in the external environment when the cleaning operation is not being performed.

[0052] In some embodiments, the lifting assembly 5 may include a pneumatic cylinder, which may be connected to the cleaning assembly 4 and control the movement of the cleaning assembly 4. The pneumatic cylinder has a simple design structure, which reduces the structural design difficulty of the cleaning equipment, saves the internal space of the cleaning equipment, and improves the space utilization rate of the cleaning equipment.

[0053] In other embodiments, the lifting assembly 5 may also include a hydraulic cylinder connected to the cleaning assembly 4 , and the hydraulic cylinder may be used to control the movement of the cleaning assembly 4 .

[0054] In some embodiments, the lifting assembly 5 includes a cylinder 50 and a piston 52 .

[0055] The cylinder body 50 may be fixedly connected to the main machine 1 . The piston 52 may be disposed in the cylinder body 50 , and the piston 52 may be connected to the fixed shaft 33 .

[0056] The piston 52 can move in the cylinder 50 as the pressure in the cylinder 50 changes. When the piston 52 moves, it can drive the fixed shaft 33 to move relative to the main unit 1, so that the driving member 3 and the cleaning component 4 can move relative to the main unit 1, so that the cleaning component 4 can match different working states of the cleaning equipment by changing its position relative to the main unit 1.

[0057] Exemplarily, the lifting assembly 5 can move the cleaning assembly 4 in a direction away from the main body 1 , so that the cleaning assembly 4 can contact the cleaning target.

[0058] The lifting assembly 5 can also move the cleaning assembly 4 toward the main body 1, thereby reducing the probability that the cleaning assembly 4 is contaminated by touching objects in the external environment when the cleaning operation is not being performed.

[0059] In some embodiments. Figure 4 As shown, the lifting assembly 5 includes: a cylinder 50 is provided with an air flow channel 54;

[0060] Gas can enter the cylinder 50 from the air flow channel 54 to form a positive pressure in the cylinder 50, and the piston 52 can be moved in the first direction under the action of the gas pressure.

[0061] The gas may also leave the cylinder 50 from the air flow channel 54 to form a negative pressure in the cylinder 50 , and the piston 52 may be moved in a second direction under the action of the gas pressure, wherein the first direction and the second direction are two opposite directions.

[0062] By controlling the movement of the cleaning component 4 in the first direction or the second direction through the lifting component 5, the position of the cleaning component 4 relative to the host 1 can be controlled, so that the cleaning component 4 can match different working states of the cleaning device by changing its position relative to the host 1.

[0063] Exemplarily, the first direction may be a direction in which the cleaning component 4 moves away from the host 1 , so that the cleaning component 4 can contact the cleaning target.

[0064] The second direction may be a direction for moving the cleaning component 4 closer to the host 1 , thereby reducing the probability that the cleaning component 4 is contaminated by touching objects in the external environment when not performing a cleaning operation.

[0065] In some embodiments, Figure 4 As shown, the cylinder body 50 may be provided with a second through hole 53, and the wire required for the operation of the driving member 3, illustratively, the wire may be a power line, which may enter through the second through hole 53. The cylinder body 50 is connected to the driving member 3 so that the driving member 3 can operate normally.

[0066] In some embodiments, the second through hole 53 may be provided with a sealant, which may seal the gap between the second through hole and the wire, thereby allowing the wire to enter the cylinder 50 while ensuring the airtightness of the cylinder 50 .

[0067] Exemplarily, the sealing member may be a sealing member formed by dispensing glue.

[0068] Figure 5 It is a schematic structural diagram of a piston and a driving member according to an exemplary embodiment.

[0069] In some embodiments, Figure 2 and Figure 5 As shown, the piston 52 may be provided with a first threaded hole 51, and the first threaded hole 51 may be a through hole with threads provided on the inner wall of the piston 52. One end of the fixed shaft 33 close to the lifting assembly 5 may be provided with a threaded end 331, that is, one end of the fixed shaft 33 close to the lifting assembly 5 may be provided with threads.

[0070] The fixed shaft 33 is fixedly connected to the piston 52 of the lifting assembly 5 through the first threaded hole 51 and the threaded end 331, that is, the fixed shaft 33 and the lifting assembly 5 can be threadedly connected, so that the fixed shaft 33 and the lifting assembly 5 are firmly connected, and the lifting assembly 5 can stably drive the driving member 3 and the cleaning assembly 4 to move relative to the main machine through the fixed shaft 33. In addition, since the lifting assembly 5 is fixedly connected to the main machine, the fixed connection between the fixed shaft 33 and the main machine can be further strengthened through the fixed connection between the fixed shaft 33 and the lifting assembly 5, thereby limiting the relative rotation of the fixed shaft 33 and the main machine, so that the rotating part 34 rotating relative to the fixed shaft 33 can rotate relative to the main machine 1, which can make the cleaning assembly 4 connected to the rotating part 34 rotate relative to the main machine 1, so that the cleaning assembly 4 can complete the cleaning operation through the rotational movement.

[0071] Furthermore, since the size of the rotating portion 34 in the radial direction of the rotating shaft is larger than the size of the fixed shaft 33 in the radial direction of the rotating shaft, the rotating portion 34 can output a larger torque without a reduction gearbox.

[0072] The present invention directly connects the rotating part 34 to the cleaning component 4, and fixes the fixed shaft 33 of the driving member 3 to the main body 1 through the clamping part 21 of the fixing member 2, and the fixed connection relationship between the lifting component 5 and the fixed shaft 33, so as to limit the rotation of the driving member 3 relative to the main body 1, thereby making the rotating part 34 rotate relative to the main body 1. This enables the rotating part 34 to directly drive the cleaning component 4 and output a larger torque in a smaller space, thereby saving the reduction box and other transmission components, providing a larger installation space for the cleaning equipment, and reducing the operating noise of the cleaning equipment.

[0073] In some embodiments, Figure 2 and Figure 4 As shown, the first threaded hole 51 can be opposite to the first through hole, which can make the fixed shaft 33 passing through the first through hole directly opposite to the first threaded hole 51, so that the threaded portion of the fixed shaft 33 can pass through the first through hole and be threadedly connected to the first threaded hole 51. This can reduce the required length of the fixed shaft 33 while ensuring the connection relationship between the fixed shaft 33 of the driving member 3 and the lifting assembly 5, and make the fixed shaft 33 be set as a linear shaft, thereby reducing the volume of the driving member 3 and providing a larger installation space for the cleaning device.

[0074] In some embodiments, Figure 2 and Figure 4 As shown, the cleaning assembly 4 may include an interference connection 41 .

[0075] The rotating part 34 can be interference connected with the interference connection part 41, so that the rotating part 34 and the cleaning component 4 form a directly connected fixed connection relationship, and then when the rotating part 34 rotates relative to the main body and the fixed shaft 33, it can drive the cleaning component 4 to rotate relative to the main body and the fixed shaft 33, so that the cleaning component 4 can complete the cleaning operation through rotational motion.

[0076] The present disclosure enables the rotating part 34 to directly drive the cleaning assembly 4 and output a larger torque in a smaller space, thereby saving a reduction box and other transmission components, providing a larger installation space for the cleaning equipment and reducing the operating noise of the cleaning equipment.

[0077] For example, Figure 2 and Figure 4 As shown, the interference connection portion 41 can be an annular wall structure that matches the shape of the rotating portion 34. The rotating portion 34 can achieve an interference connection with the interference connection portion 41, so that the rotating portion 34 and the cleaning component 4 form a directly connected fixed connection relationship. When the rotating portion 34 rotates relative to the main body and the fixed shaft 33, the cleaning component 4 can be driven to rotate relative to the main body and the fixed shaft 33.

[0078] In some embodiments, Figure 2 and Figure 4 As shown, the fixing member 2 may include a fixing portion 22 connected to the clamping portion 21, and the fixing portion 22 may be disposed between the lifting assembly 5 and the host 1. The fixing member 2 may be fixedly connected to the lifting assembly 5 and the host 1 through the fixing portion 22.

[0079] The lifting assembly 5 may be provided with a first threaded portion 62, and the lifting assembly 5 may be fixedly connected to the fixing portion 22 through the first threaded portion 62. The first threaded portion 62 may be configured as a protruding structure having a screw hole inside. Since the thickness of the physical structure of the lifting assembly 5 and the fixing portion 22 is relatively small, in order to increase the path length of the thread, a protruding first threaded portion 62 is provided on the lifting assembly 5, so that the thickness of the physical structure where the thread can be provided is increased through the structural thickness of the protruding first threaded portion 62, thereby making the fixed connection between the lifting assembly 5 and the fixing member 2 more firm and reliable, improving the stability of the driving member 3 during operation, and enhancing the reliability of the cleaning device.

[0080] In some embodiments, Figure 1 , Figure 2 and Figure 3 As shown, there may be multiple first threaded portions 62. By providing multiple first threaded portions 62, the fixed connection relationship between the lifting component 5 and the fixing member 2 can be enhanced, thereby making the connection relationship between the lifting component 5 and the fixing member 2 more secure, thereby enhancing the reliability of the cleaning equipment.

[0081] In addition, multiple first threaded portions 62 can be arranged around the first threaded hole 51, which can make the fixed connection relationship between the lifting component 5 and the fixing portion 22 more uniform in all directions, thereby making the fixed connection relationship between the lifting component 5 and the fixing member 2 more stable, thereby improving the stability of the driving member 3 during operation and enhancing the reliability of the cleaning equipment.

[0082] In some embodiments, Figure 2 As shown, the lifting assembly 5 may include a third threaded portion 63 , and the lifting assembly 5 may be fixedly connected to the host 1 via the third threaded portion 63 .

[0083] The third threaded portion 63 can be configured as a raised structure with a screw hole inside. Since the physical structure thickness of the lifting component 5 and the main machine 1 part used to set the lifting component 5 is relatively small, in order to increase the path length of the thread, a raised third threaded portion 63 is provided on the lifting component 5, so that the thickness of the physical structure where the thread can be set is increased by the raised structural thickness of the third threaded portion 63, thereby making the fixed connection between the lifting component 5 and the main machine 1 more firm and reliable, improving the stability of the driving member 3 during operation, and enhancing the reliability of the cleaning device.

[0084] In some embodiments, Figure 1 , Figure 2 and Figure 3 As shown, there may be multiple third threaded portions 63. By providing multiple third threaded portions 63, the fixed connection relationship between the lifting assembly 5 and the host 1 can be enhanced, thereby making the connection relationship between the lifting assembly 5 and the host 1 more secure, thereby enhancing the reliability of the cleaning device.

[0085] In addition, multiple third threaded portions 63 can be arranged around the second threaded hole, which can make the fixed connection relationship between the lifting assembly 5 and the main unit 1 more uniform in all directions, thereby making the fixed connection relationship between the lifting assembly 5 and the main unit 1 more stable, improving the stability of the driving member 3 during operation, and enhancing the reliability of the cleaning equipment.

[0086] In some embodiments, the rotating portion 34 can be interference connected with the interference connection portion 41 of the cleaning component 4, so that the rotating portion 34 and the cleaning component 4 form a directly connected fixed connection relationship, and then when the rotating portion 34 rotates relative to the main body and the fixed shaft 33, it can drive the cleaning component 4 to rotate relative to the main body and the fixed shaft 33, so that the cleaning component 4 as a cleaning component can complete the cleaning operation of the cleaning target through its own rotational movement.

[0087] Exemplarily, the cleaning assembly may include cleaning parts such as a mop, a roller brush, and a sweeping brush.

[0088] The present invention is directly connected to the cleaning assembly 4 through the rotating part 34, and the fixed shaft 33 is limited to rotate relative to the main machine 1 through the fixing effect of the fixing member 2, so that the fixed shaft 33 will not rotate relative to the main machine 1, and then the rotating part 34 rotating relative to the fixed shaft 33 can rotate relative to the main machine 1, so as to drive the functional module to rotate and complete the cleaning operation. And because the radial size of the rotating part 34 in the rotating shaft is larger than the radial size of the fixed shaft 33 in the rotating shaft, the rotating part 34 can output a larger torque without a reduction box. By having a larger output torque in a smaller space, the reduction box and other transmission components are saved, a larger installation space is provided for the cleaning equipment, and the operating noise of the cleaning equipment is reduced.
