[0043] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0046] See also Figures 1 to 8 The utility model provides a cleaning device, which is mainly used in cleaning equipment.

[0047] There is no restriction on the form of the cleaning equipment. In actual application, the cleaning equipment can be operated in a vertical state, in a horizontal state, or in a state that can switch between the vertical state and the horizontal state; the cleaning equipment can be operated by the user to achieve handheld walking, or can achieve autonomous walking on a planned path under the coordinated action of a pre-set control program and related drives.

[0048] Cleaning equipment is generally pre-set with cleaning parts, which are used to clean the surface to be cleaned. There is no restriction on the specific type of the surface to be cleaned, which can be but not limited to the ground, stairs, glass, etc.; there is no restriction on the cleaning method of the surface to be cleaned by the cleaning parts, which can be but not limited to sweeping, mopping, vacuuming, scraping, etc. As the cleaning method of the surface to be cleaned by the cleaning parts is different, the types of cleaning parts are also different, which can be but not limited to one or more of the side brush, roller brush, cleaning cloth, etc.

[0049] In view of the above, the cleaning equipment can be used alone or in conjunction with the base station. The cleaning equipment and the base station can be connected wirelessly or by wire, etc., without limitation. In actual application, the cleaning equipment can generally run automatically according to the instructions input by the user in real time or the pre-compiled program of the body, such as automatic planning of the forward trajectory, targeted start-up of the cleaning function, charging, water replenishment, sewage discharge, self-cleaning, etc. For this reason, it can be understood that the cleaning equipment and / or the base station used in conjunction with the cleaning equipment are generally equipped with a control device, and the control device includes, for example, a control chip that can compile a program, a control circuit composed of related electrical components, etc. The control device is used to electrically connect at least some of the functional components on the cleaning equipment and / or the base station, so as to be able to communicate with each other, such as detection signals, control instructions, etc., which will not be described in detail.

[0050] The following mainly takes the cleaning device as a sweeper, and the above-mentioned cleaning member as a roller brush as an example for explanation. For the convenience of explanation, in the following embodiments, the cleaning device has a substantially vertical up-down direction and a horizontal plane as an example for explanation, and the horizontal plane has a substantially vertical lateral and longitudinal direction. When the cleaning device is used to walk on the surface to be cleaned, at least the longitudinal direction can be set as the walking direction of the cleaning device.

[0051] Specifically, the cleaning device includes a base 100, a dust box 200, a roller brush module 300, an air duct housing 400, a cover plate 500 and a switching device 600. The base 100 is respectively provided with a first through hole 110 and a second through hole 120 in the up-down direction; the dust box 200 is provided on the base 100; at least a part of the roller brush module 300 is movably installed in the first through hole 110 in the up-down direction, and the roller brush module 300 is provided with a first air duct 313 connecting the first through hole 110 and the dust box 200; the air duct housing 400 is provided on the base 100, and the air duct housing 400 is provided with a second air duct 413 connecting the second through hole 120 and the dust box 200; the cover plate 500 is movably installed In the dust box 200, there is a first position that connects the first air duct 313 and blocks the second air duct 413, and a second position that blocks the first air duct 313 and connects the second air duct 413; the switching device 600 is respectively connected to the roller brush module 300 and the cover plate 500, and the switching device 600 is used to alternately switch between lifting and lowering the roller brush module 300, and when lifting the roller brush module 300, drives the cover plate 500 to move to the first position; and when lowering the roller brush module 300, drives the cover plate 500 to move to the second position.

[0052] In the technical solution provided by the present invention, when the switching device 600 drives the roller brush module 300 to descend to a position where it partially protrudes downward from the first through hole 110, on the one hand, the surface to be cleaned can be cleaned by rotating the roller brush in the roller brush module 300; on the other hand, since the first air duct 313 is connected, the roller brush can carry away the dirt on the surface to be cleaned together with the first air duct 313; when the switching device 600 drives the roller brush module 300 to be lifted to an angle away from the first through hole 110, the fluffy dirt on the surface to be cleaned can be directly sucked away through the connected second air duct 413. At this time, since the first air duct 313 is blocked and the roller brush is separated from the surface to be cleaned, the fluffy dirt will basically not be wrapped around the roller brush, thereby effectively solving the problem of hair entangled in the roller brush.

[0053] Please combine Figures 1 to 3 , the base 100 can be set to any shape, size and material according to actual needs. For example, as shown in the figure, the base 100 is roughly rectangular. The base 100 can specifically include a bottom shell and a cover shell. The bottom shell and the cover shell are detachably connected, and when connected, the two together define a substantially closed (for example, the area other than the first through hole 110 and the second through hole 120 is closed) receiving cavity; and when detached, the receiving cavity is opened. In this way, the receiving cavity can be convenient for receiving and installing, for example, the above-mentioned dust box 200, roller brush module 300, air duct shell 400 and switching device 600.

[0054] The first through hole 110 and the second through hole 120 are respectively provided on the bottom shell in the up-down direction, that is, at least through the bottom of the base 100. The first through hole 110 and the second through hole 120 can be arranged in a horizontal or vertical interval, for example Figure 2 As shown, the first through hole 110 and the second through hole 120 may be arranged at intervals along the longitudinal direction, and each of the first through hole 110 and the second through hole 120 extends in an elongated shape along the transverse direction.

[0055] Please combine Figure 8 The dust box 200 is disposed on the base 100, and can be disposed on the upper surface of the bottom shell, that is, in the receiving cavity. The dust box 200 can be disposed at any position in the arrangement direction of the first through hole 110 and the second through hole 120, for example, on the side of the first through hole 110 away from the second through hole 120, on the side of the second through hole 120 away from the first through hole 110, or between the first through hole 110 and the second through hole 120. Figures 1 to 3 As shown, the first through hole 110 and the second through hole 120 are arranged adjacent to each other, and the dust box 200 is arranged on a side of the first through hole 110 away from the second through hole 120 .

[0056] The dust box 200 may include a detachably connected box body 210 and a box cover 220, and when connected, the box body 210 and the box cover 220 jointly enclose a dust outlet chamber 211, and the dust chamber 211 has a sewage inlet 213. The shell wall of the box body 210 with the sewage inlet 213 can be defined as a first shell wall 212. The first air duct 313 and the second air duct 413 are both connected to the sewage inlet 213. The dust chamber 211 is generally also provided with an air outlet.

[0057] To this end, the cleaning device may further include, for example, a fan, the air suction side of the fan being connected to the air outlet to drive the air flow carrying dirt into the dust chamber 211 through the first air duct 313 and the second air duct 413 .

[0058] The cleaning device may further include a dust shield 230, which is disposed in the dust chamber 211, and a movable cover is disposed at the dirt inlet 213, which can be flipped to cover the inside of the dirt inlet 213, and flipped to open the dirt inlet 213. In this way, the dust shield 230 is equivalent to driving the dust shield 230 to open only when an airflow is formed to enter the dust chamber 211 through the first air duct 313 and the second air duct 413; when on the contrary, an airflow is formed to enter the first air duct 313 or the second air duct 413 from the dust chamber 211, the dust shield 230 will not open, and maintain the state of covering the inside of the dirt inlet 213, so as to prevent the dirt in the dust box 200 from being discharged outward through the first air duct 313 and the second air duct 413 in the opposite direction.

[0059] The roller brush module 300 is installed at the first through hole 110. It can be understood that the roller brush module 300 includes a mounting shell 310 and a roller brush assembly. A first air duct 313 is formed inside the mounting shell 310, and the roller brush in the roller brush assembly is rotatably mounted in the first air duct 313 along the transverse axis, or in other chambers formed in the mounting shell 310 and connected to the first air duct 313, and at least partially exposed outside the mounting shell 310.

[0060] The roller brush module 300 can be installed in the first through hole 110 in a vertically movable manner as a whole, or only the roller brush assembly can be installed in the first through hole 110 in a vertically movable manner, so as to have a working state in which at least a part of the roller brush assembly protrudes downward from the first through hole 110, and a non-working state in which the roller brush assembly is upwardly away from the first through hole 110. It can be understood that when in the working state, the roller brush assembly can be close to the surface to be cleaned and wipe the surface to be cleaned; when in the non-working state, the roller brush assembly is sufficiently away from the surface to be cleaned and basically does not clean the surface to be cleaned.

[0061] In view of the above, it can be known that the installation shell 310 defines a first air duct 313, one air duct opening of the first air duct 313 is connected to the first through hole 110 to form a first dirt suction port 313a; another air duct opening of the first air duct 313 is connected to the dust box 200 to form a first connecting port 313b. Similarly, the air duct shell 400 defines a second air duct 413, one air duct opening of the second air duct 413 is connected to the second through hole 120 to form a second dirt suction port 413a; another air duct opening of the second air duct 413 is connected to the dust box 200 to form a second connecting port 413b.

[0062] When the air duct housing 400 is integrally formed with the base 100, the second through hole 120 directly constitutes the second dirt suction port 413a. When the mounting housing 310 and / or the air duct housing 400 is integrally formed with the dust box 200, the first connecting port 313b and / or the second connecting port 413b correspondingly constitute the above-mentioned dirt inlet 213. Figures 4 to 7 In the structure shown, the air duct housing 400, the base 100, the dust box 200 and the mounting housing 310 are all detachably connected.

[0063] Since the mounting shell 310 may be installed on the base 100 in a manner that it can be lifted and lowered in the vertical direction, in order to keep the connection between the air duct shell 400 and the dust box 200 tight:

[0064] In one embodiment, the dust box 200 may be fixedly connected to the mounting shell 310 , and the dust box 200 may be driven by the mounting shell 310 to move up and down.

[0065] Or in one embodiment, the mounting shell 310 defines a first air duct 313, and the mounting shell 310 is made of a flexible material at least at the connection between the first air duct 313 and the dust box 200. Specifically, the flexible material may be an elastic material that can be elastically deformed under the action of an external force and can be reset when the external force is removed. Thus, when the mounting shell 310 is driven by the switching device 600 to be lifted or lowered, the flexible material can adapt to the lifting and lowering movement of the mounting shell 310 through elastic deformation, but does not affect the fixed connection between the mounting shell 310 and the dust box 200.

[0066] Specifically, the mounting shell 310 includes a first rigid shell 311 and a first elastic shell 312, the first rigid shell 311 extends in a cylindrical shape in the transverse direction, the first elastic shell 312 extends from the radial side of the first rigid shell 311 toward the dust box 200, and is fixedly connected to the dust box 200, one of the connection points of the first rigid shell 311 and the first elastic shell 312 is provided with a card slot, and the other is provided with a card convex, which is fixed in the card slot; the roller brush module 300 also includes a roller brush assembly, which is rotatably mounted in the first rigid shell 311 along the transverse axis, and the first rigid shell 311 and the first elastic shell 312 jointly define a first air duct 313. It can be understood that the first rigid shell 311, that is, a shell structure made of rigid material, has sufficient structural strength, and basically will not be deformed under the action of external force, which helps to maintain the overall structural shape of the first rigid shell 311, so that the roller brush assembly is more stable when installed in the first rigid shell 311. The first elastic shell 312 is a shell structure made of elastic material, which can produce a certain elastic deformation under the action of external force.

[0067] And / or, for the air duct housing 400, similarly, the air duct housing 400 is made of a flexible material at least at the connection point between the second air duct 413 and the dust box 200. Specifically, the air duct housing 400 includes a second rigid shell 411 and a second elastic shell 412, the second rigid shell 411 is arranged on the upper side of the first rigid shell 311, and is suitable for the shape of the first rigid shell 311 to extend in an arc shape; the second elastic shell 412 continues to extend from the port of the second rigid shell 411 toward the dust box 200, and is fixedly connected to the dust box 200, one of the connection points of the second rigid shell 411 and the second elastic shell 412 is provided with a card slot, and the other is provided with a card convex, the card convex is fixed in the card slot, and the second rigid shell 411 and the second elastic shell 412 jointly define the second air duct 413.

[0068] In practical application, the first elastic shell 312 and the second elastic shell 412 can be separately provided and connected to the first shell wall 212 of the dust box 200. Alternatively, the first elastic shell 312 and the second elastic shell 412 can be integrally formed and connected to the first shell wall 212 of the dust box 200.

[0069] In actual application, the first connecting port 313b and the second connecting port 413b can be arranged in sequence on the first shell wall 212 in the up-down direction. Specifically, the first connecting port 313b can be arranged below the second connecting port 413b. Optionally, at least the air duct section of the second air duct 413 connected to the first shell wall 212 gradually extends downwardly in an inclined manner so that the fluffy dirt can fall down. The cover plate 500 is installed on the first shell wall 212 in a movably translatable manner in the up-down direction, which helps to simplify the movement of the cover plate 500 and also simplifies the structure of the cover plate 500 and the switching device 600.

[0070] Based on one or more of the above embodiments, the switching device 600 first needs to drive the roller brush module 300 to move up and down. Specifically, it can be a combination of a motor and a gear rack mechanism, a combination of a motor and a lead screw nut mechanism, etc. In this embodiment, the switching device 600 includes an abutment block 610, a swing rod 620, a driver 630 and a cam 640. The abutment block 610 is arranged on one longitudinal side of the roller brush module 300; the swing rod 620 is arranged on one lateral side of the abutment block 610, one end of the swing rod 620 is rotatably mounted on the base 100 along the lateral axis, and the other end is fixedly connected to the roller brush module 300; the driver 630 includes a main body and an output shaft rotatably arranged along the lateral axis, and the main body is fixedly connected to the swing rod 620; the cam 640 is installed on the output shaft and rolls against the upper surface of the abutment block 610 to drive the roller brush module 300 to rise and fall during its rotation.

[0071] Specifically, since the roller brush module 300 extends in an elongated shape in the transverse direction, two rocker arms 620 can be provided and arranged at intervals in the transverse direction. One section of the rocker arm 620 can be integrally formed with, for example, the mounting shell 310 of the roller brush module 300, or can be detachably or non-detachably connected after split molding. Another section of the rocker arm 620 can be rotatably mounted on the base 100 via a rotating shaft structure. When the output shaft of the driver 630 rotates, the cam 640 is driven to roll and abut against the upper surface of the abutment block 610. When the outer convex periphery of the cam 640 abuts against the upper surface of the abutment block 610, the roller brush module 300 is driven to be lifted upward by the rocker arm 620; conversely, when the inner concave periphery of the cam 640 abuts against the upper surface of the abutment block 610, the roller brush module 300 is driven to drop downward by the rocker arm 620.

[0072] When the cover plate 500 is provided as described above, the switching device 600 further includes a wire reel 650 and a traction wire 660. The wire reel 650 is coaxially mounted on the output shaft, and a wire reel groove 651 is provided along the circumference of the output shaft; one section of the traction wire 660 is wound in the wire reel groove 651, so as to be driven by the wire reel 650 to perform a wire reeling stroke and a wire unwinding stroke, and the other section is connected to the cover plate 500 to drive the cover plate 500 to move up and down. By adjusting the winding direction of the traction wire 660 in the wire reel groove 651, it can adapt to the position of the first channel opening and the second channel opening, so as to achieve the above switching purpose. For example, the first channel opening is arranged below the second channel opening: when the outer convex periphery of the cam 640 abuts against the upper surface of the abutting block 610, the roller brush module 300 is driven to lift upwards through the swing rod 620; at the same time, the wire reel 650 drives the wire reeling groove 651 to perform a wire reeling stroke, drives the cover plate 500 to move upwards to cover the first channel opening, and opens the second channel opening. Conversely, when the inner concave periphery of the cam 640 abuts against the upper surface of the abutting block 610, the roller brush module 300 is driven to drop downwards through the swing rod 620; at the same time, the wire reel 650 drives the wire reeling groove 651 to perform a wire unwinding stroke, drives the cover plate 500 to move downwards to cover the second channel opening, and opens the first channel opening.

[0073] Next, the traction line 660 includes a main line segment 661 arranged near the winding groove 651, and at least two branch line segments 662 connected to the free end of the main line segment 661. Each branch line segment 662 is dispersedly connected to different parts of the cover plate 500. For example, each branch line segment 662 can be arranged along the lateral intervals and fixedly connected to the cover plate 500, which helps to improve the stability of the cover plate 500 when it moves up and down.

[0074] Furthermore, in one embodiment, the dust box 200 is provided with a slide groove 214 extending up and down on the side of the cover plate 500, and the cover plate 500 is provided with a sliding protrusion 510 protruding toward the inside of the slide groove 214, the sliding protrusion 510 is slidably connected to the slide groove 214, and the traction line 660 is connected and fixed to the sliding protrusion 510. The slide groove 214 can define an accurate sliding direction and sliding path for the sliding protrusion 510, which helps to further make the up and down movement of the cover plate 500 smoother and more stable.

[0075] Furthermore, in one embodiment, the switching device 600 further includes an elastic member 700, which is installed in the slide groove 214 and clamped between the slide groove 214 and the sliding protrusion 510. The elastic member 700 is deformed when the traction line 660 performs a winding stroke, and resets when the traction line 660 performs a releasing stroke, so as to drive the cover plate 500 to switch between the first position and the second position together with the traction line 660. The elastic member 700 is specifically, for example, a spring member, which can be sleeved on the outside of the traction line 660 and the sliding protrusion 510.

[0076] The above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the utility model.
