Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features.

[0035] An embodiment of the utility model provides a cleaning module, which is used for a cleaning robot. The cleaning robot is, for example, a sweeping robot, a mopping robot, or a sweeping and mopping robot. The cleaning robot includes a body and a cleaning module, and the cleaning module is mounted on the body. In some embodiments, the cleaning module includes a cleaning component for cleaning the floor, and the cleaning component is located at the bottom of the body of the body. The cleaning component can be a component for sweeping the floor, or a component for mopping the floor.

[0036] Figure 1 , Figure 2 The three-dimensional exploded schematic diagram and the three-dimensional half-section schematic diagram of an embodiment of the cleaning module of the utility model are respectively shown. The cleaning module includes a limiting sleeve 100, a cleaning assembly 200, a driving member 300, and a rotating lifting member 400. The limiting sleeve 100 is fixedly connected to the bottom of the body of the cleaning robot. Figure 3 , Figure 4 They are respectively a three-dimensional exploded schematic diagram and a three-dimensional exploded half-section schematic diagram of a limiting sleeve and a rotating lifting member in one embodiment of the cleaning module of the utility model. Figure 4 The inner circumference of the limiting sleeve 100 is provided with a spiral groove 110 and an annular groove 120 . The annular groove 120 is located at the bottom of the spiral groove 110 and communicates with the spiral groove 110 .

[0037] The cleaning assembly 200 is mounted on the rotating lifting member 400, and the driving member 300 can drive the rotating lifting member 400 to rotate inside the limiting sleeve 100. A limiting protrusion 410 is provided on the outer periphery of the rotating lifting member 400.

[0038] In this embodiment, the cleaning module is described by taking the cleaning component 200 as a mop component as an example. The mop component cleans the ground by rotating relative to the ground and mopping the ground.

[0039] The cleaning module has a lifting state and a working state. When the rotary lifting member 400 rotates forward, the limiting protrusion 410 spirally descends along the spiral groove 110 into the annular groove 120, and rotates around the annular groove 120, so that the cleaning module changes from the lifting state to the working state. When the rotary lifting member 400 is reversed, the limiting protrusion 410 enters the spiral groove 110 from the annular groove 120, and spirally rises along the spiral groove 110, so that the cleaning module changes from the working state to the lifting state. Herein, the forward rotation and reverse rotation of the rotary lifting member 400 are two oppositely set rotation directions. In one example, from a top-down angle, the rotary lifting member 400 rotates in a clockwise direction for forward rotation, and correspondingly, the rotary lifting member 400 rotates in a counterclockwise direction for reverse rotation.

[0040] According to the cleaning module of the embodiment of the utility model, the inner circumference of the limiting sleeve 100 is provided with a spiral groove 110 and an annular groove 120, and the annular groove 120 is located at the bottom of the spiral groove 110 and is connected with the spiral groove 110. The outer circumference of the rotary lifting member 400 is provided with a limiting protrusion 410, and the driving member 300 can drive the rotary lifting member 400 to rotate inside the limiting sleeve 100. When the cleaning module needs to be transformed into a working state, the rotary lifting member 400 rotates forward, and at this time the limiting protrusion 410 spirally descends along the spiral groove 110 into the annular groove 120, and rotates around the annular groove 120, that is, the driving member 300 drives the cleaning component 200 to first descend to the point where it can contact the ground, and then continues to drive the cleaning component 200 to rotate continuously, thereby cleaning the ground. When the cleaning module needs to be transformed into the lifting state, the rotary lifting member 400 is reversed, and the limiting protrusion 410 enters the spiral groove 110 from the annular groove 120 and spirally rises along the spiral groove 110, that is, the driving member 300 drives the cleaning component 200 to lift relative to the ground, so that the cleaning component 200 leaves the ground. In the above state switching process, only a single driving member 300 is required in each cleaning module to realize the driving of the cleaning component 200 to rise, descend and rotate for cleaning, which reduces the demand for the driving member 300 in the cleaning module, and the space occupied by the driving member 300 in the cleaning module is smaller, making the structure of the cleaning module more streamlined and reducing the manufacturing cost of the cleaning module.

[0041] In the related conventional technology, a separate driving device is used to drive the gear and the damping ring to rotate forward and reverse in sequence to realize the lifting and lowering of the cleaning component. According to the cleaning module of the above-mentioned embodiment of the utility model, the lifting and lowering of the cleaning component 200 is realized by the spiral cooperation between the rotating lifting member 400 and the limiting sleeve 100, and there is no need to set a damping ring, thereby avoiding the risk of the damping ring being easily ineffective.

[0042] like Figure 2As shown, in some embodiments, the cleaning module further includes an elastic member 500, which is disposed between the cleaning assembly 200 and the rotating lifting member 400. In the working state, the elastic member 500 elastically presses the cleaning assembly 200 against the ground. When the rotating lifting member 400 is reversed, the limiting protrusion 410 can enter the spiral groove 110 from the annular groove 120 under the elastic force of the elastic member 500. In the working state, the elastic member 500 elastically presses the cleaning assembly 200 against the ground, which can improve the cleaning effect of the cleaning assembly 200 on the ground. When the driving member 300 is reversed, the elastic member 500 gives the limiting protrusion 410 an upward force, so that it can enter the spiral groove 110 from the annular groove 120 more conveniently and smoothly during the rotation process, thereby ensuring the smoothness of the cleaning module when switching from the working state to the lifting state. In this embodiment, the elastic member 500 is a coil spring, and both ends of the elastic member 500 are disposed between the cleaning component 200 and the rotating lifting component 400. In the working state, the elastic member 500 is in a compressed state. In some other embodiments, the elastic member 500 can also be an elastic sleeve, a spring, or other component that can provide elastic force between the cleaning component 200 and the rotating lifting component 400.

[0043] In some embodiments, the cleaning module further includes a transmission sleeve 600. The transmission sleeve 600 is sleeved between the rotating lifting member 400 and the limiting sleeve 100. The circumferential wall surface of the transmission sleeve 600 is penetrated with a guide opening 610 in a preset pattern, and the limiting protrusion 410 passes through the guide opening 610. The transmission sleeve 600 is transmission-connected to the driving member 300, and when the guide opening 610 and the limiting protrusion 410 are laterally opposed to each other, the transmission sleeve 600 can drive the rotating lifting member 400 to rotate. The guide opening 610 is used to fix the rotating lifting member 400 in place when the driving member 300 rotates forward or reversely. By providing the guide opening 610 in a preset pattern, a preset rotation virtual position exists between the transmission sleeve 600 and the rotating lifting member 400. When the transmission sleeve 600 starts to rotate forward in the lifting state, or when the transmission sleeve 600 starts to rotate reversely in the working state, the transmission sleeve 600 first rotates relative to the rotary lifting member 400 by a preset angle so that the guide opening 610 and the limiting protrusion 410 are laterally abutted against each other, and then drives the rotary lifting member 400 to rotate. The driving member 300 is in transmission connection with the transmission sleeve 600, and the driving member 300 drives the transmission sleeve 600 to rotate within the limiting sleeve 100 by a preset angle first, and then the transmission sleeve 600 drives the rotary lifting member 400 to rotate relative to the limiting sleeve 100.

[0044] like Figure 3As shown, in some embodiments, the guide opening 610 includes a longitudinal portion 611, a first transverse portion 612, and a second transverse portion 613. The longitudinal portion 611 extends in the longitudinal direction, the first transverse portion 612 extends transversely and communicates with the bottom of the longitudinal portion 611, and the second transverse portion 613 extends transversely and communicates with the top of the longitudinal portion 611. The longitudinal portion 611 is used to guide the up and down movement of the rotating lifting member 400. The first transverse portion 612 is used to fix the rotating lifting member 400 when the rotating lifting member 400 is separated from the spiral groove 110 and drive the rotating lifting member 400 to rotate continuously along the annular groove 120, thereby driving the cleaning assembly 200 to rotate continuously to clean the floor. The second transverse portion 613 is used to fix the rotating lifting member 400 in place when the driving member 300 is reversed, so as to prevent the rotating lifting member 400 from automatically descending under the action of gravity.

[0045] In some embodiments, the cleaning module further includes a transmission assembly 700 . The transmission sleeve 600 is transmission-connected to the output shaft 750 via the transmission assembly 700 . In this embodiment, the transmission assembly 700 includes a gearbox 710, a worm 720, a secondary gear 730, an output gear 740, an output shaft 750, a first bearing 760 and a second bearing 770. The gearbox 710 includes a gearbox upper shell 711 and a gearbox lower shell 712. The gearbox upper shell 711 and the gearbox lower shell 712 enclose a receiving chamber. The gearbox 710 is fixedly connected to a limiting sleeve 100 and an output shaft 750. The limiting sleeve 100 is fixedly arranged at the bottom of the gearbox 710; the worm 720 is arranged in the receiving chamber, and the worm 720 is connected to the output shaft 750. The output shaft 750 can drive the worm 720 to rotate forward or reverse; the secondary gear 730 is installed in the receiving chamber through a bearing, and one end of the large gear of the secondary gear 730 is meshed with the worm 720, and the worm 720 can drive the secondary gear 730 to rotate forward or reverse; The output gear 740 is arranged in the accommodating cavity, and the output gear 740 is meshed with one end of the pinion of the secondary gear 730. The secondary gear 730 can drive the output gear 740 to rotate forward or reversely; the output shaft 750 is vertically arranged in the accommodating cavity, the output shaft 750 is passed through the axis of the output gear 740, and the lower end of the output shaft 750 is passed through the top of the output shaft 750; the first bearing 760 is fixedly arranged in the accommodating cavity, the first bearing 760 is sleeved on the upper end of the output shaft 750 for fixing the output shaft 750, the first bearing 760 is an oil-containing bearing, and a retaining spring 780 is arranged between the first bearing 760 and the output gear 740; the second bearing 770 is sleeved on the top of the output shaft 750 for fixing the output shaft 750, the second bearing 770 is a ball bearing, and the first bearing 760 and the second bearing 770 can also be interchangeable or other types of bearings can be selected.

[0046] In the above embodiment, when the driving member 300 is powered on, the driving member 300 drives the worm 720 in the gear box 710 to rotate, the worm 720 drives the secondary gear 730 to rotate, the secondary gear 730 drives the output gear 740 to rotate, the output gear 740 drives the transmission sleeve 600 to rotate through the output shaft 750, the transmission sleeve 600 drives the rotating lifting member 400 to rotate, the rotating lifting member 400 drives the cleaning component 200 to rotate, thereby completing the transmission of the driving member 300 and the cleaning component 200.

[0047] In some embodiments, the cleaning module also includes an in-place detection member 800, which is arranged on the inner circumferential surface of the limiting sleeve 100. The in-place detection member 800 is electrically connected to the driving member 300. When the cleaning module is converted into a lifting state, the rotating lifting member 400 triggers the in-place detection member 800. The driving member 300 can stop and drive the rotating lifting member 400 to reverse when the in-place detection member 800 is triggered.

[0048] In this embodiment, the in-place detection member 800 is a micro switch. In some embodiments, the in-place detection member 800 is at least partially disposed in the spiral groove 110, and the position-limiting protrusion 410 can trigger the in-place detection member 800 when it moves to the in-place detection member 800.

[0049] In some other embodiments, the in-place detection element 800 is not limited to a micro switch, but may also be other in-place detection elements such as a Hall element or a photoelectric switch.

[0050] In some embodiments, the cleaning component 200 is detachably connected to the rotating lifting member 400. The detachable cleaning component 200 is convenient for the user to clean the cleaning component 200 or replace the consumables.

[0051] In some embodiments, the cleaning assembly 200 includes a bracket 210 and a cleaning member 220, the bracket 210 includes a support plate 211 and a connecting column 212, the cleaning member 220 is installed on the support plate 211, and the connecting column 212 can extend into the rotating lifting member 400 to be detachably connected with the rotating lifting member 400. When the rotating lifting member 400 rotates, the connecting column 212 is driven to rotate, and the connecting column 212 drives the support plate 211 to rotate, and the cleaning member 220 on the support plate 211 performs a rotating cleaning on the ground. In this embodiment, a Velcro is fixedly provided on the support plate 211, and the Velcro adheres to the cleaning member 220 to fix the support plate 211 and the cleaning member 220. The cleaning member 220 can also be made into a shape that can be set on the support plate 211, or a fixed buckle is provided on the support plate 211, and the cleaning member 220 is clamped on the support plate 211. The cleaning member 220 can be a common reusable material such as a cleaning brush, a cleaning cloth or a cleaning sponge.

[0052] In some embodiments, a first magnetic member 910 is provided on the top of the rotating lifting member 400, and a second magnetic member 920 is provided on the top of the connecting column 212. In this embodiment, the first magnetic member 910 is an iron sheet fixedly disposed on the rotating lifting member 400, and the second magnetic member 920 is a magnet fixedly disposed on the top of the connecting column 212. The first magnetic member 910 and the second magnetic member 920 cooperate with each other to connect the rotating lifting member 400 and the cleaning component 200 in a magnetic manner, so that the user can disassemble the cleaning component 200 conveniently.

[0053] In the above embodiment, when the cleaning module is powered on and running, the driving member 300 drives the transmission sleeve 600 to rotate forward or reverse through the worm 720, the secondary gear 730, the output gear 740 and the output shaft 750 in the gear box 710. When the transmission sleeve 600 rotates forward, since the limiting sleeve 100 is fixed, the rotating lifting member 400 will move downward in the transmission sleeve 600 according to the trajectory of the guide opening 610 due to the restriction of the spiral groove 110 on the inner wall of the limiting sleeve 100, and will eventually be restricted by the first horizontal portion 612. At this time, the rotating lifting member 400 has fallen out of the restriction of the spiral groove 110 and entered the annular groove 120, and can continuously rotate at the bottom, thereby achieving the effect of cleaning the floor. When the rotary lifting member 400 descends, due to the effect of gravity, the elastic member 500 disposed between the rotary lifting member 400 and the cleaning assembly 200 is compressed by the rotary lifting member 400 and the ground, so that when the cleaning assembly 200 contacts the ground, there is an elastic force between the rotary lifting member 400 and the cleaning assembly 200. When the transmission sleeve 600 reverses, under the effect of the elastic force, the limiting protrusion 410 of the rotary lifting member 400 rises, rotates from the annular groove 120 into the spiral groove 110, and under the effect of the driving member 300, it continuously rises in the spiral groove 110 until it hits the in-place detection member 800 in the annular groove 120. When the in-place detection member 800 is triggered, the driving member 300 stops driving the rotary lifting member 400 to reverse, thereby completing the lifting process.

[0054] The utility model also provides a cleaning robot. The cleaning robot is, for example, a sweeping robot, a mopping robot, or a sweeping and mopping robot. The cleaning robot includes a body and a cleaning module of any of the aforementioned embodiments, the cleaning module being mounted on the body. In some embodiments, the cleaning assembly is located at the bottom of the body of the body.

[0055] The cleaning module includes a limiting sleeve 100, a cleaning assembly 200, a driving member 300, and a rotating lifting member 400. The limiting sleeve 100 is fixedly connected to the bottom of the body of the cleaning robot. The inner circumference of the limiting sleeve 100 is provided with a spiral groove 110 and an annular groove 120, and the annular groove 120 is located at the bottom of the spiral groove 110 and is connected to the spiral groove 110. The cleaning assembly 200 is installed on the rotating lifting member 400, and the driving member 300 can drive the rotating lifting member 400 to rotate inside the limiting sleeve 100. The outer periphery of the rotating lifting member 400 is provided with a limiting protrusion 410. The cleaning module has a lifting state and a working state. When the rotating lifting member 400 rotates forward, the limiting protrusion 410 spirally descends along the spiral groove 110 into the annular groove 120, and rotates around the annular groove 120, so that the cleaning module is changed from a lifting state to a working state. When the rotary lifting member 400 is reversed, the limiting protrusion 410 enters the spiral groove 110 from the annular groove 120 and spirally rises along the spiral groove 110 , so that the cleaning module is transformed from the working state to the lifting state.

The inner circumferential surface of the limiting sleeve 100 of the cleaning module is provided with a spiral groove 110 and an annular groove 120, and the annular groove 120 is located at the bottom of the spiral groove 110 and is connected with the spiral groove 110. The outer periphery of the rotating lifting member 400 is provided with a limiting protrusion 410, and the driving member 300 can drive the rotating lifting member 400 to rotate inside the limiting sleeve 100. When the cleaning module needs to be transformed into a working state, the rotating lifting member 400 rotates forward, and at this time the limiting protrusion 410 spirally descends along the spiral groove 110 into the annular groove 120, and rotates around the annular groove 120, that is, the driving member 300 drives the cleaning component 200 to first descend to the point where it can contact the ground, and then continues to drive the cleaning component 200 to rotate continuously, thereby cleaning the ground. When the cleaning module needs to be changed to the lifting state, the rotary lifting member 400 is reversed, and the limiting protrusion 410 enters the spiral groove 110 from the annular groove 120 and spirally rises along the spiral groove 110, that is, the driving member 300 drives the cleaning assembly 200 to lift relative to the ground, so that the cleaning assembly 200 leaves the ground. In the above state switching process, only a single driving member 300 is required in each cleaning module to realize the driving of the cleaning assembly 200 to rise, descend and rotate for cleaning, which reduces the demand for the driving member 300 in the cleaning module, and the space occupied by the driving member 300 in the cleaning module is smaller, making the structure of the cleaning module more streamlined, and reducing the manufacturing cost of the cleaning module and the cleaning robot.

[0057] The above are only preferred embodiments of the present invention, and do not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
