Description

Technical Field

[0001] The present application relates to the technical field of cleaning devices, and in particular to a cleaning module and a cleaning system. Background Art

[0002] Nowadays, people's pace of life is getting faster and faster, and more time needs to be devoted to busy activities such as work and study. As a result, the time available for cleaning living and working environments is decreasing. Therefore, when it is necessary to clean the work surface (especially in relatively narrow and difficult-to-clean areas), a relatively simple cleaning method is usually used: rotating between using a broom and a mop to manually sweep and mop the work surface. However, this traditional cleaning method not only consumes a lot of time and reduces cleaning efficiency, but also increases the user's labor intensity and poor user experience. In addition, the broom and mop are two different cleaning tools, resulting in a large number of cleaning tools, large size, and difficult storage and management. Utility Model Content

[0003] Based on this, it is necessary to provide a cleaning module and a cleaning system to address the problems of time-consuming and labor-intensive cleaning, low cleaning efficiency, and difficulty in storage and management.

[0004] In a first aspect of the present application, a cleaning module is provided, comprising:

[0005] A carrier shell, the carrier shell comprising a first surface and a second surface disposed opposite to each other;

[0006] a floor brushing assembly, the floor brushing assembly being arranged on the first surface and capable of performing a floor brushing operation when the floor brushing assembly contacts the working surface;

[0007] a sewage suction component, the sewage suction component being disposed on the second surface and being capable of performing sewage suction operations when the sewage suction component contacts the working surface; and

[0008] A rotating shaft assembly is movably connected to the carrier shell so that the carrier shell has rotational freedom. The cleaning module can be selectively used to perform floor brushing or dirt suction operations by contacting the working surface with the floor brushing assembly or the dirt suction assembly.

[0009] In the cleaning module of this solution, a brush assembly and a dirt suction assembly are integrated and installed on the first and second surfaces of the carrier shell respectively, and a rotating shaft assembly is also installed on the carrier shell. The rotating shaft assembly provides the carrier shell with rotational freedom. Therefore, when in use, the carrier shell is rotated by the rotating shaft assembly to make the brush assembly contact with the working surface and at the same time make the dirt suction assembly away from the working surface. At this time, the brush assembly moves back and forth to perform a brushing operation on the working surface to clean the stains on the working surface; then, the carrier shell is rotated by the rotating shaft assembly to adjust the dirt suction assembly to contact the working surface and make the brush assembly away from the working surface. At this time, the dirt suction assembly can remove sewage and other dirt on the working surface. The stains are sucked away, thereby completing the cleaning operation of the work surface; that is to say, the rotational freedom of the carrier shell is provided by the rotating shaft assembly, which enables the floor brushing assembly and the dirt suction assembly to be flexibly switched to meet the cleaning needs of brushing and sucking dirt on the work surface, and the floor brushing assembly and the dirt suction assembly are integrated into the carrier shell as one, so that the degree of integration of the cleaning module is high, and there is no need to frequently replace cleaning tools during cleaning operations, thereby saving cleaning time, improving cleaning efficiency, and reducing the labor intensity of the user. The floor brushing assembly and the dirt suction assembly are compactly and reasonably arranged on the carrier shell, which is convenient for storage and management, and is conducive to improving the user's sense of experience.

[0047] Figure 1 and Figure 2 This is a schematic diagram of a partial structure of a cleaning module 100 according to one embodiment of the present application. This cleaning module 100 can be connected as an accessory to cleaning equipment such as floor scrubbers and vacuum cleaners to perform cleaning operations such as scrubbing or vacuuming the work surface. It is understood that the work surface referred to in this application can include, but is not limited to, floors, walls, and windows to be cleaned. It can also include surfaces such as desktops and car windows.

[0048] Please continue reading Figure 1 and Figure 2 , and combined with Figure 3 For example, the cleaning module 100 includes a housing 10, a floor brush assembly 20, a dirt suction assembly 30, and a shaft assembly 40. The housing 10 is the main body of the cleaning module 100, used to support and fix the floor brush assembly 20, the dirt suction assembly 30, and the shaft assembly 40. The floor brush assembly 20 and the dirt suction assembly 30 are respectively mounted on the housing 10.

[0049] Specifically, the housing 10 includes a first surface and a second surface disposed opposite each other. The floor scrubbing assembly 20 is disposed on the first surface, and the dirt suction assembly 30 is disposed on the second surface. When the floor scrubbing assembly 20 contacts the work surface, it can be used to scrub the floor. When the dirt suction assembly 30 contacts the work surface, it can be used to suction dirt.

[0050] The rotating shaft assembly 40 is connected to the carrier shell 10 to provide the carrier shell 10 with rotational freedom, so that the cleaning module 100 can selectively contact the working surface through the floor brushing assembly 20 or the dirt suction assembly 30 and can be used to perform floor brushing or dirt suction operations.

[0051] Please continue reading Figure 3 In an optional embodiment of the present application, the carrier housing 10 includes a first shell 11 and a second shell 12 that are detachably connected. The detachable connection between the first shell 11 and the second shell 12 facilitates regular cleaning of the interior of the carrier housing 10, preventing the accumulation of dirt and grime. The first shell 11 and the second shell 12 can be made of any of plastic, sheet metal, or other materials. The connection between the first shell 11 and the second shell 12 can be, but is not limited to, at least one of a screw connection, a snap connection, and a magnetic connection, and can be flexibly selected based on actual needs.

[0052] For example, the surface of the first housing 11 facing away from the second housing 12 is defined as the first surface, and the floor brush assembly 20 is disposed on the surface of the first housing 11 facing away from the second housing 12. The surface of the second housing 12 facing away from the first housing 11 is defined as the second surface, and the dirt suction assembly 30 is disposed on the surface of the second housing 12 facing away from the first housing 11. This ensures that when one of the floor brush assembly 20 and the dirt suction assembly 30 contacts the work surface, the other can be more reliably kept away from the work surface, thereby preventing interference between the floor brush assembly 20 and the dirt suction assembly 30, or between the floor brush assembly 20 and objects in the work environment, or between the dirt suction assembly 30 and objects in the work environment. This ensures that the cleaning module 100 can fully exert its cleaning capabilities and improves the reliability of the cleaning operation. In addition, when one of the floor brushing assembly 20 and the dirt suction assembly 30 contacts the working surface, the other is stacked above the one contacting the working surface along the height direction of the cleaning module 100. Compared with the arrangement on one side, the floor brushing assembly 20 or the dirt suction assembly 30 on the top will not cause too much obstruction to the user's view of the working surface, which is more conducive to the user's visual judgment of the cleaning effect of the working surface, and can also more effectively drive the cleaning module 100 to move on the working surface, balance the cleaning effect and cleaning efficiency, and avoid the appearance of dead corners on the working surface that cannot be cleaned.

[0053] In summary, the implementation of the technical solution of this embodiment will achieve the following beneficial effects: in the cleaning module 100 of this solution, the first surface and the second surface of the carrier shell 10 are respectively integrated with the brush assembly 20 and the dirt suction assembly 30, and the carrier shell 10 is also installed with a rotating shaft assembly 40. The rotating shaft assembly 40 provides the carrier shell 10 with a degree of freedom of rotation. Therefore, when in use, the carrier shell 10 is rotated by the rotating shaft assembly 40 to make the brush assembly 20 contact with the working surface and at the same time make the dirt suction assembly 30 away from the working surface. At this time, the brush assembly 20 moves back and forth and can perform a brushing operation on the working surface to clean the stains on the working surface; thereafter, the carrier shell 10 is rotated by the rotating shaft assembly 40, and the dirt suction assembly 30 can be adjusted to contact the working surface and make the brush assembly 20 away from the working surface. At this time, the dirt suction component 30 can suck away the sewage and other stains on the working surface, thereby completing the cleaning operation of the working surface; that is, the rotational freedom of the carrier shell 10 is provided by the rotating shaft component 40, so that the floor brushing component 20 and the dirt suction component 30 can be flexibly switched to meet the cleaning needs of brushing and sucking dirt on the working surface, and the floor brushing component 20 and the dirt suction component 30 are integrated into the carrier shell 10 as a whole, so that the degree of integration of the cleaning module 100 is high, and there is no need to frequently replace cleaning tools during cleaning operations, thereby saving cleaning time, improving cleaning efficiency, and reducing the labor intensity of the user. The floor brushing component 20 and the dirt suction component 30 are compactly and reasonably arranged on the carrier shell 10, which is convenient for storage and management, and is conducive to improving the user's experience.

[0054] Please refer again Figure 1 、 Figure 3 , and combined with Figure 4In another embodiment, the second shell 12 is provided with a shaft mounting position 13. The shaft assembly 40 includes a shaft body 41, which is rotatably disposed in the shaft mounting position 13. The first shell 11 is fixedly connected to the second shell 12, and the first shell 11 presses the shaft body 41 in the shaft mounting position 13. The provided shaft mounting position 13 can be installed and matched with the shaft body 41, and the shaft body 41 can rotate along its own axis in the shaft mounting position 13. When the user pushes and pulls the cleaning module 100 back and forth, the shaft assembly 40 can adapt to the push-pull movement and rotate up and down relative to the carrier shell 10, ensuring that the user controls the cleaning module 100 in a comfortable operating posture, reducing the user's workload, and improving the cleaning effect. During this process, the first shell 11 always presses the shaft body 41 in the shaft mounting position 13 to prevent the shaft body 41 from loosening and shifting, ensuring that the shaft assembly 40 and the carrier shell 10 rotate smoothly and reliably relative to each other. Alternatively, as an alternative to the above embodiment, in another optional embodiment, the first housing 11 is provided with a shaft mounting position 13, the shaft assembly 40 includes a shaft body 41, and the shaft body 41 is rotatably disposed within the shaft mounting position 13. The second housing 12 is fixedly connected to the first housing 11, and the second housing 12 presses the shaft body 41 to be retained in the shaft mounting position 13. This embodiment can achieve substantially the same technical effects as the above embodiment, and therefore will not be described in detail here.

[0055] In other words, a shaft mounting position 13 is provided on any one of the first shell 11 and the second shell 12 of the carrier shell 10; the shaft body 41 is rotatably disposed in the shaft mounting position 13, and the remaining one of the first shell 11 and the second shell 12 presses the shaft body 41 to be confined in the shaft mounting position 13.

[0056] It should be noted that the aforementioned shaft mounting position 13 can be specifically configured as an arcuate groove that mates with the cylindrical shaft body 41 in an arc-shaped manner to ensure normal rotation. Furthermore, the outer peripheral wall of the shaft body 41 is formed with multiple recessed holes, which significantly reduces the contact area between the shaft body 41 and the arcuate groove. This, in turn, reduces frictional resistance during relative rotation, improves the smoothness of relative rotation between the carrier housing 10 and the shaft assembly 40, and reduces the rotational force applied by the user.

[0057] Please continue reading Figure 4 Furthermore, based on the above embodiment, the rotating shaft assembly 40 further includes an intermediate connecting shaft 42. The intermediate connecting shaft 42 is connected to the rotating shaft body 41, and the axis of the intermediate connecting shaft 42 is arranged at an angle to the axis of the rotating shaft body 41. For example, in the embodiment of the present application, the intermediate connecting shaft 42 and the rotating shaft body 41 are integrally formed, and the axis of the intermediate connecting shaft 42 is perpendicular to the axis of the rotating shaft body 41. In this case, the intermediate connecting shaft 42 and the rotating shaft body 41 cooperate to form a T-shaped rotating shaft.

[0058] Please continue reading Figure 5 In addition, the first housing 11 defines a first clearance recess 111, and the second housing 12 defines a second clearance recess 121. When the cleaning module 100 is used for suction operations, the suction assembly 30 contacts the work surface, and the first clearance recess 111 accommodates the intermediate connecting shaft 42 that rotates close to the first housing 11. When the cleaning module 100 is used for floor scrubbing operations, the floor scrubbing assembly 20 contacts the work surface, and the second clearance recess 121 accommodates the intermediate connecting shaft 42 that rotates close to the second housing 12.

[0059] For details, please refer to Figure 4 、 Figure 5 Combined with Figure 1 When the cleaning module 100 is being used for vacuuming, the first housing 11 and the floor scrubbing assembly 20 are positioned above the second housing 12. When the user pulls the intermediate connecting shaft 42 to move the carrier housing 10 backward, the intermediate connecting shaft 42 rotates upward relative to the second housing 12, bringing it closer to the first housing 11. When the intermediate connecting shaft 42 rotates upward to its maximum angle, the pre-set first clearance recess 111 can accommodate the intermediate connecting shaft 42. This arrangement prevents the first housing 11 from obstructing the intermediate connecting shaft 42 when the user pulls the cleaning module 100 backward. It also increases the maximum rearward travel of the suction assembly 30, increasing the suction area and improving cleaning efficiency.

[0060] For details, please refer to Figure 4 、 Figure 5 Combined with Figure 2 When the cleaning module 100 is used for floor scrubbing, the floor scrubbing assembly 20 contacts the work surface, and the second clearance recess 121 accommodates the intermediate connecting shaft 42, which rotates close to the second housing 12. Similarly, at this time, the second housing 12 and the dirt suction assembly 30 are located above the first housing 11. When the user pulls the intermediate connecting shaft 42 to drive the carrier housing 10 backward, the intermediate connecting shaft 42 rotates relative to the carrier housing 10 and approaches the second housing 12. When the intermediate connecting shaft 42 rotates upward to its maximum angle, the preset second clearance recess 121 can accommodate the intermediate connecting shaft 42. This arrangement can similarly prevent the second housing 12 from blocking the intermediate connecting shaft 42 when the user pulls the cleaning module 100 backward, while also increasing the maximum backward travel of the floor scrubbing assembly 20, increasing the floor scrubbing area and improving cleaning efficiency.

[0061] Further, please refer again to Figures 3 to 5 The cleaning module 100 further includes a switching assembly 50. One end of the switching assembly 50 is connected to the intermediate connecting shaft 42, and the other end of the switching assembly 50 is used to connect to the air circuit of the sewage suction system of the cleaning equipment.

[0062] Specifically, if Figure 4 and Figure 5 As shown, the adapter assembly 50 includes a hollow rotating sleeve 51. The rotating sleeve 51 is rotatably connected to the intermediate connecting shaft 42, with the axis of the rotating sleeve 51 coaxial with the axis of the intermediate connecting shaft 42. By rotating the intermediate connecting shaft 42 relative to the rotating sleeve 51, the user can switch between the floor scrubbing assembly 20 and the dirt suction assembly 30 in contact with the work surface. This simplifies switching between the cleaning modules 100, reduces user labor, and improves cleaning efficiency.

[0063] Also, please continue reading Figure 6 and Figure 7 , and combined with Figure 5 In addition to the above embodiment, the adapter assembly 50 further includes a positioning pin 52. The outer wall of the intermediate connecting shaft 42 defines an annular positioning groove 421 extending around its axis. The rotating sleeve 51 defines a positioning hole 511 extending through its sidewall. The rotating sleeve 51 is positioned over the exterior of the intermediate connecting shaft 42 so that the positioning hole 511 aligns with the annular positioning groove 421. The positioning pin 52 is inserted into the positioning hole 511, with one end extending into the annular positioning groove 421. With the positioning pin 52 inserted into both the positioning hole 511 and the annular positioning groove 421, when the intermediate connecting shaft 42 and the rotating sleeve 51 rotate relative to each other, the positioning pin 52 slides along the annular positioning groove 421, providing a rotational guide and limiter, thereby enhancing the smooth rotation of the adapter assembly 50 and the rotating shaft assembly 40. Furthermore, one end of the positioning pin 52, inserted into the annular positioning groove 421, also serves to axially limit the intermediate connecting shaft 42 and the rotating sleeve 51, preventing the adapter assembly 50 from loosening and separating from the rotating shaft assembly 40.

[0064] Please continue reading Figure 6 and Figure 7 Furthermore, the shaft assembly 40 further includes a second sewage suction channel 43. Specifically, the interconnected intermediate connecting shaft 42 and the shaft body 41 are configured as an internal hollow structure, and this hollow structure constitutes the second sewage suction channel 43.

[0065] See also Figure 8 Combined with Figure 5 The second housing 12 is provided with a first sewage suction port 122 and a first sewage suction channel 123. Specifically, the first sewage suction port 122 is provided on the bottom wall of the second housing 12; a curved double-layered enclosure structure 126 is provided on the top wall of the second housing 12. The space enclosed by the double-layered enclosure constitutes the first sewage suction channel 123. The first sewage suction port 122 is connected to the middle position of the first sewage suction channel 123. The dirt sucked in through the first sewage suction port 122 is diverted from both sides of the first sewage suction channel 123 and then passes through the second sewage suction channel 43 and the hollow rotating sleeve 51 of the adapter assembly 50.

[0066] In the embodiment illustrated in the drawings of this application, the floor brush assembly 20 is specifically configured as bristles. The bristles can be attached to the first surface of the carrier housing 10 through a process such as planting. In other embodiments not shown in the drawings, the floor brush assembly 20 can also be configured as a scouring pad, mop, etc., which can be secured to the first surface of the carrier housing 10 through Velcro, magnets, or a sleeve. The floor brush assembly 20 is used to clean stains on the work surface through friction with the work surface.

[0067] Please refer again Figure 4 、 Figure 5 , and combined with Figure 7 、 Figure 8 The dirt suction assembly 30 includes a first scraper 31 and a second scraper 32 that are spaced apart, and a first dirt suction port 122 located between the first scraper 31 and the second scraper 32. Specifically, the first scraper 31 and the second scraper 32 are fixed to the second shell 12 by a snap-fit method. That is, the second shell 12 is provided with a first buckle 124 and a second buckle 125, and the first buckle 124 and the second buckle 125 are arranged side by side and spaced apart along the front-back movement direction of the cleaning module 100; the first scraper 31 is provided with a first card body 311, and the first card body 311 is detachably connected to the first buckle 124 by snap-fitting; the second scraper 32 is provided with a second card body 321, and the second card body 321 is detachably connected to the second buckle 125. The first scraper 31 and the second scraper 32 are installed in a snap-fit manner, which is convenient for maintenance and replacement.

[0068] Furthermore, the first scraper 31 and the second scraper 32 are configured as soft rubber strips. When the cleaning module 100 is pushed or pulled on the working surface, the first scraper 31 and the second scraper 32 can bend in opposite directions of movement.

[0069] When the dirt suction component 30 of the cleaning module 100 contacts the working surface and is used for dirt suction operations, under the action of the cleaning module 100's own gravity and the downward pressure applied by the user, the first scraper 31 and the second scraper 32 contact the working surface. As the cleaning module 100 moves back and forth on the working surface, the first scraper 31 and the second scraper 32 bend in directions opposite to the direction of movement, and the stains are peeled off the working surface and gathered into the narrow semi-enclosed space surrounded by the first scraper 31 and the second scraper 32, and are recovered in sequence through the first dirt suction port 122, the first dirt suction channel 123, the second dirt suction channel 43 and the rotating sleeve 51.

[0070] Furthermore, the first scraper 31 and the second scraper 32 are serrated on the side away from the carrier housing 10. The serrated scraper is more conducive to the dirt passing through the serrated notch and being collected in the space enclosed by the first scraper 31 and the second scraper 32.

[0071] Furthermore, if Figure 4 and Figure 5As shown, two auxiliary wheels 33 are mounted at both ends of the space enclosed by the first scraper 31 and the second scraper 32. The height of the two auxiliary wheels 33 protruding from the second housing 12 is no greater than the height of the first scraper 31 and the second scraper 32 protruding from the second housing 12. This ensures smoother movement of the cleaning module 100 when vacuuming dirt from the work surface and prevents damage to the first scraper 31 and the second scraper 32 due to excessive bending and deformation caused by heavy pressure.

[0072] Please continue reading Figure 4 and Figure 5 Furthermore, at least one support wheel 127 is provided on the rear side of the second scraper 32 of the second housing 12. The support wheel 127 enables the cleaning module 100 to contact the working surface more balancedly when the dirt suction assembly 30 contacts the working surface, thereby reducing the difficulty of operation for the user. Figure 4 and Figure 5 In the illustrated embodiment, two support wheels 127 are symmetrically arranged. The two support wheels 127 ensure that the suction assembly 30 maintains consistent ground pressure on both ends when in contact with the work surface, preventing uneven suction at both ends. Furthermore, the arrangement of the two support wheels 127 and the two auxiliary wheels 33 creates a trapezoidal distribution of four wheels, providing stable support for the cleaning module 100, ensuring a stable posture and ensuring effective and efficient cleaning.

[0073] Furthermore, if Figure 9 As shown, the cleaning module 100 also includes a pipe assembly 60. One end of the pipe assembly 60 is connected to the rotating shaft assembly 40 via the adapter assembly 50, and the other end of the pipe assembly 60 can be used to connect to the air circuit of the sewage suction system of the cleaning equipment. It is understood that the sewage suction system of the cleaning equipment generally includes a sewage suction fan, a filter element, a sewage collection box, and a sewage inlet. When the cleaning module 100 is used as an accessory in conjunction with the cleaning equipment, the other end of the pipe assembly 60 of the cleaning module 100 is connected to the sewage inlet of the sewage suction system of the cleaning equipment, thereby forming the air circuit of the cleaning system.

[0074] Please continue to see Figure 9 Furthermore, the pipe assembly 60 also includes a hard tube 61 and a gripping member 62. One end of the hard tube 61 is connected to the rotating sleeve 51 via a pneumatic connection, and the other end of the hard tube 61 is connected to the gripping member 62 via a pneumatic connection. The gripping member 62 is conveniently held by the user. The gripping member 62 is connected to the rotating sleeve 51 via the hard tube 61, thereby achieving a rigid connection with the carrier housing 10. When the user grips the gripping member 62 and applies a pushing or pulling force to the carrier housing 10, the carrier housing 10 is pushed or pulled back and forth, enabling the floor scrubbing assembly 20 to scrub the work surface or the dirt suction assembly 30 to suck dirt from the work surface.

[0075] For example, the hard tube 61 can be any one of a hard plastic tube, a metal tube, etc. The hard tube 61 can be a single tube, or can be composed of two or more pipes, which can be selected according to actual needs.

[0076] The gripping member 62 can be any one of a rod, a ring, a plate, etc. In order to prevent slipping and affecting the operating experience, the outer wall of the gripping member 62 is provided with an anti-slip structure, such as anti-slip lines, an array of protrusions, etc.

[0077] Furthermore, the pipe assembly 60 includes a soft tube 63, one end of which is connected to the grip 62 for air communication, and the other end of which can be connected to the air communication of the sewage collection tank's sewage inlet. The soft tube 63 can optionally be, but is not limited to, a rubber tube or a corrugated tube. The provision of the soft tube 63 allows for flexible expansion of the cleaning module 100's operating range, freeing it from the constraints of rigid piping.

[0078] In addition, the present application also provides a cleaning system, which includes a cleaning device and a cleaning module 100 of any of the above embodiments. The cleaning module 100 can be connected to the air circuit of the sewage suction system of the cleaning device.

[0079] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0080] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
