[0040] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they may refer to a fixed connection, an indirect connection via an intermediate medium, internal communication between two components, or an interaction between two components. Those skilled in the art will understand the specific meanings of these terms in this application based on specific circumstances.

[0041] In the description of this application, it should be understood that the terms "upper", "lower", "front", "back", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application.

[0042] The terms "first", "second", "third" (if any) in the description and claims of the present application and above drawings are used to distinguish similar objects, and do not necessarily indicate a specific order or sequence. It should be understood that the data thus used can be interchanged under appropriate circumstances, so that the embodiments of the present application described herein can be implemented in an order other than that illustrated or described herein.

[0043] In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion, for example, a process, method, system, product or maintenance tool including a series of steps or units does not have to be limited to those steps or units clearly listed, but can include other steps or units not clearly listed or inherent to these processes, methods, products or maintenance tools.

[0044] In order to make the purposes, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0045] The cleaning device generally comprises a housing and a fan unit arranged in the housing, and an airflow generated by the fan unit generates suction at a suction port of the housing, and a roller brush can be arranged at a position corresponding to the suction port, and the roller brush is rolled on a surface to be cleaned to bring up dust and hair, and the dust and hair are sucked into the device through the suction of the suction port to realize the cleaning function.

[0046] However, at present, during the cleaning process of the cleaning device, the hair is easy to be entangled on the roller brush, and cannot be sucked into the device. Taking a mite removal instrument as an example, the mite removal instrument can remove dust and worms on the surface of a bed quilt, a skin, etc. The hair adhered to the bed quilt is usually more, when the roller brush of the mite removal instrument is rolled on the surface of the bed quilt, the hair is easy to be entangled on the roller brush, and with the rolling of the roller brush, the entangled hair will be more and more tightly entangled to the two ends of the roller brush, and cannot be sucked away, which will also cause the cleaning of the roller brush to be time-consuming and laborious.

[0047] In order to solve the above technical problems, an embodiment of the present application provides a cleaning device, which designs the setting position and structure of the air suction port on the cleaning device, sets the air suction port in front of the roller brush assembly along the cleaning direction, and sets a blocking structure between the air suction port and the cavity where the roller brush assembly is located. Before the roller brush assembly contacts the hair fibers, the fiber hair on the surface to be cleaned is first sucked into the air duct through the air suction port, and the roller brush assembly rubs and slaps the surface to be cleaned to pick up dust and small particles of debris, and sucks them into the air suction port. In this way, the amount of hair entangled on the roller brush can be reduced, the cleaning efficiency can be improved, and the roller brush after cleaning is more convenient to clean.

[0048] The following first illustrates an example of the application scenario of the cleaning device provided in the embodiment of the present application.

[0049] The cleaning device provided in the embodiment of the present application is a cleaning tool with a roller brush structure. Specifically, the product types of the cleaning device in the embodiment of the present application may include but are not limited to a mite remover, a vacuum cleaner, a sweeper, a sweeping robot, etc. Depending on the product type, the cleaning device provided in the embodiment of the present application can be used to clean the floor, clothes, bedding, sofa furniture, etc., and the embodiment of the present application does not make specific limitations on this.

[0050] Figure 1 A front view of a cleaning device provided in an embodiment of the present application; Figure 2 for Figure 1 Cross-sectional view in the AA direction; Figure 3 for Figure 2 Partial view of the middle C position; Figure 4 for Figure 2 Cross-sectional view along the BB direction.

[0051] See also Figures 1 to 4 As shown, the present application provides a cleaning device 10 , which includes a roller brush assembly 100 and a device body 200 . The device body 200 has a roller brush cavity 203 , and the roller brush assembly 100 is rotatably disposed in the roller brush cavity 203 .

[0052] When the cleaning device 10 is cleaning the surface to be cleaned, the roller brush cavity 203 is set toward the surface to be cleaned, the roller brush assembly 100 is facing the surface to be cleaned, and the roller brush assembly 100 can contact the surface to be cleaned. As the device body 200 moves, the roller brush assembly 100 rolls on the surface to be cleaned. The roller brush assembly 100 can bring up dust, hair fibers and other debris on the surface to be cleaned, making it easier for dust, fiber hair, etc. adhered to the surface to be cleaned to be sucked into the inside of the device body 200.

[0053] In this embodiment of the present application, the device body 200 has a suction channel 201 and a suction port 202 connected to the suction channel 201. The suction port 202 is located at the front end of the roller brush cavity 203 along a first direction. It will be understood that the first direction is the cleaning direction of the cleaning device 10. When the cleaning device 10 is moved forward along the first direction to clean the surface to be cleaned, the suction port 202 first passes through the area being cleaned, and then the roller brush passes through the area being cleaned. In this way, the suction port 202 can first suck away hair fibers, preventing them from becoming entangled in the roller brush.

[0054] In some embodiments, a blocking rib 210 is provided on one side of the roller brush cavity 203 near the air intake port 202. The blocking rib 210 has a connecting groove 212 that connects the roller brush cavity 203 and the air intake port 202. The airflow generated by the negative pressure suction of the air intake port 202, on the one hand, flows into the air intake port 202 from the area directly opposite it, and on the other hand, the airflow from the roller brush cavity 203 carries dust particles picked up by the roller brush assembly 100 and flows through the connecting groove 212 to the air intake port 202.

[0055] The first direction is defined as the X direction, that is, the cleaning direction of the cleaning device 10 is the X direction. Moving forward along the X direction, the suction port 202 passes through the cleaned area first, and the roller brush passes through the area later; and moving backward along the X direction, the roller brush passes through the cleaned area first, and the suction port 202 passes through the area later.

[0056] It is understandable that in actual application scenarios, the general cleaning operation is to push the cleaning device 10 forward along the X direction for cleaning, then lift the cleaning device 10, and then repeat the operation; or, push the cleaning device 10 forward along the X direction, and then pull the cleaning device 10 backward along the X direction, and so on.

[0057] It should be noted that in the cleaning device 10 provided in the embodiment of the present application, by setting the suction port 202 at the front end of the roller brush cavity 203, during the cleaning process, the suction port 202 can first suck the hair fibers and large particles of debris into the suction channel 201, and the blocking ribs 210 can block the fiber hair from entering the roller brush cavity 203, preventing the fiber hair from being entangled on the roller brush assembly 100 at the rear, and the roller brush assembly 100 can rub and pat the surface to be cleaned to bring up dust and fine particles and enter the suction port 202 through the connecting groove 212, thereby achieving a good cleaning effect.

[0058] First, the structure of the barrier rib 210 will be described in detail below.

[0059] Please continue to refer to Figures 1 to 4In one possible implementation, the blocking ribs 210 and the air intake port 202 both extend along the second direction, with the length of the blocking ribs 210 matching the length of the air intake port 202. The second direction is perpendicular to the first direction. Thus, as the air intake port 202 draws in hair fibers, the blocking ribs 210 can prevent hair fibers from entering the roller brush cavity 203 at different locations along the length of the roller brush cavity 203.

[0060] It can be understood that the blocking rib 210 separates the air suction port 202 and the roller brush cavity 203 to form two areas. The air flow can carry dust and small particles through the connecting groove 212 through the blocking rib 210 to ensure that the negative pressure suction generated by the air suction port 202 can act on the inside of the roller brush cavity 203. At the same time, during the forward movement of the cleaning device 10, when the air suction port 202 sucks up the hair fibers, the blocking rib 210 can prevent the limited hair from entering the roller brush cavity 203.

[0061] The second direction is defined as the Y direction. The rotation axis of the roller brush assembly 100 is parallel to the Y direction, and the length direction of the roller brush cavity 203 is parallel to the Y direction. The blocking rib 210 is provided along the Y direction on one side of the roller brush cavity 203 near the air inlet 202 .

[0062] Exemplarily, the distribution length of the blocking rib 210 may be equal to the length of the rolling brush cavity 203 , or the distribution length of the blocking rib 210 may be slightly greater than the length of the rolling brush cavity 203 .

[0063] In some embodiments, the blocking rib 210 may include a plurality of first tooth-shaped portions 211 spaced apart along the length direction of the air suction port 202, and a connecting groove 212 is formed between adjacent first tooth-shaped portions 211, thereby improving the efficiency of the airflow in driving the dust particles in the roller brush cavity 203 to pass through the blocking rib 210.

[0064] It can be understood that the first tooth-shaped portions 211 arranged along the second direction form a linear array structure, that is, multiple first tooth-shaped portions 211 form multiple connecting grooves 212 to ensure that each position in the length direction of the roller brush cavity 203 can be connected with the air suction port 202 through the connecting grooves 212. In this way, the dust particles that are beaten and floated at each position in the length direction of the roller brush assembly 100 can be efficiently sucked into the air suction port 202.

[0065] Exemplarily, the first tooth-shaped portion 211 is provided with an arc chamfer structure at the top end facing the surface to be cleaned, so that the position where the first tooth-shaped portion 211 contacts the surface to be cleaned has an arc or a smooth surface, avoiding the appearance of a sharp chamfer structure. Since the first tooth-shaped portion 211 will contact the surface to be cleaned during the cleaning process, the structure of the first tooth-shaped portion 211 can avoid damage to the surface of the sheets and bedding to be cleaned.

[0066] For example, the first tooth-shaped portion 211 may be integrally formed with a structural component on the bottom side of the device body 200 .

[0067] It should be noted that the number of the first tooth-shaped portions 211 can be set according to the length of the roller brush cavity 203, and this embodiment of the present application does not specifically limit this.

[0068] In some embodiments, the bottom side of the device body 200 has a support surface 204, and the end of the first tooth-shaped portion 211 is flush with the support surface 204. The support surface 204 and the first tooth-shaped portion 211 can be located on both sides of the roller brush cavity 203 in the X direction, respectively. In this way, when the roller brush assembly 100 rotates, the cleaning member on the roller brush assembly 100 can hit the surface to be cleaned, thereby causing dust particles adhering to the surface to be cleaned to float away and be sucked into the air intake 202.

[0069] It is understandable that during the cleaning process, the first toothed portion 211 and the support surface 204 can both abut against the surface to be cleaned, avoiding gaps between the first toothed portion 211 and the surface to be cleaned that could cause fibers and hair to be missed, thereby better preventing fibers and hair from passing through.

[0070] In some embodiments, in the vertical direction, the lower edge of the suction port 202 on the side facing away from the roller brush cavity 203 is higher than the lower edge of the blocking rib 210, so that the front end of the suction port 202 can be spaced apart from the surface to be cleaned, so that fiber hair can smoothly enter the suction port 202.

[0071] It is understood that when the cleaning device 10 is performing a cleaning operation, the blocking ribs 210 and the support surface 204 on both sides of the roller brush cavity 203 are in contact with the surface to be cleaned, and the front edge of the air suction port 202 is positioned higher than the blocking ribs 210. Therefore, although the air suction port 202 is positioned toward the surface to be cleaned, the air suction port 202 does not directly press against the surface to be cleaned. In this way, under the negative pressure suction of the air suction port 202, external airflow can enter the air suction port 202, continuously producing a cleaning effect. In addition, a certain distance between the air suction port 202 and the surface to be cleaned can prevent the air suction port 202 from being blocked by flexible objects such as sheets and bedding.

[0072] Please continue to refer to Figures 1 to 4 In one possible implementation, an air inlet channel 205 is provided at the lower edge of the air suction port 202 away from the roller brush cavity 203. The air inlet channel 205 connects the inner and outer sides of the air suction port 202. When the air suction port 202 sucks air at a negative pressure, the air flow efficiency and smoothness can be improved.

[0073] It is understandable that when the cleaning device 10 cleans flexible objects such as bed sheets, as the cleaning device 10 moves, the cleaning device 10 will exert a pressing force on the flexible object, causing the flexible object to deform and become concave, which will cause the downward air suction port 202 to approach or even touch the surface to be cleaned. The setting of the air inlet channel 205 ensures that even if the air suction port 202 approaches or touches the object to be cleaned, the external airflow can still enter the air suction port 202 through the air inlet channel 205 along the lower edge of the front of the air suction port 202 in the X direction, so that the air suction port 202 can continue to generate suction and avoid the air suction port 202 being blocked.

[0074] In some embodiments, a plurality of second tooth-shaped portions 220 are provided on the lower edge of the air intake 202 on the side facing away from the roller brush cavity 203. The plurality of second tooth-shaped portions 220 are spaced apart along the length of the air intake 202, and an air inlet channel 205 is formed between adjacent second tooth-shaped portions 220. This can increase the airflow rate, thereby improving the efficiency of fibers, hair, and large particles entering the air intake 202.

[0075] It can be understood that the plurality of second tooth-shaped portions 220 are arranged along the Y direction, and the length of the second tooth-shaped portion 220 can be equal to or slightly greater than the length of the air suction port 202 along the Y direction.

[0076] In some embodiments, the device body 200 may include a shell 230 and a cover 240 . The cover 240 is covered on the bottom side of the shell 230 and is formed together with the shell 230 to form a roller brush cavity 203 . The cover 240 has an opening to expose the roller brush assembly 100 .

[0077] The blocking rib 210 is located at the front edge of the cover plate 240 along the first direction. When the roller brush assembly 100 is assembled, the cover plate 240 can be opened to avoid interference with the blocking rib 210.

[0078] For example, the blocking rib 210 can be integrally formed with the cover plate 240. The cover plate 240 and the housing 230 can be made of plastic or metal, or plastic-coated metal, which is not specifically limited in the present embodiment.

[0079] For example, the cover 240 and the housing 230 can be rotated to open and close, or the cover 240 and the housing 230 can be detachably connected by snapping.

[0080] In some embodiments, the housing 230 may include a first housing 231 and a second housing 232, wherein the first housing 231 is connected to the top of the second housing 232, and the cover 240 is connected to the bottom of the second housing 232. The first housing 231 is configured to form the air suction channel 201, and the second housing 232 is configured to form the air suction port 202.

[0081] It can be understood that by splicing the first shell 231 and the second shell 232, the internal space of the shell can be used to form an air suction channel 201, so that the position of the air suction channel 201 is close to the top to facilitate air outlet, and the position of the air suction port 202 can face downward to the cleaning surface, and the inhaled air flow can enter the air suction channel 201 from bottom to top, reducing the wind resistance during inhalation.

[0082] Illustratively, the edge shape profiles of the first shell 231 and the second shell 232 match each other, and the two can be fixedly connected by fasteners such as screws, or fixed by snaps, or connected and fixed by a combination of fasteners and snaps. The embodiments of the present application do not make specific limitations on this.

[0083] In some embodiments, the cleaning device 10 may also include a dust cup assembly 300 and a fan assembly 400. The dust cup assembly 300 and the fan assembly 400 are both arranged on the top of the device body 200. The dust cup assembly 300 is connected to the suction channel 201, and the fan assembly 400 is connected to the dust cup assembly 300.

[0084] It can be understood that the dust cup assembly 300 and the fan assembly 400 are both above the device body 200, forming an upper and lower distributed structure with the device body 200, so that the weight distribution of the whole machine is more balanced and it is convenient for the user to carry the cleaning device 10.

[0085] It should be noted that the hair fibers and dust debris sucked in by the air intake 202 can enter the dust cup assembly 300 for filtration. The dust cup assembly 300 is provided with a storage chamber and a filter element. The filtered clean airflow enters the fan assembly 400 and is then discharged. The fan assembly 400 provides power for the cleaning operation of the cleaning device 10. The airflow generated by the fan assembly 400 causes the air intake 202 to generate negative pressure suction.

[0086] As an optional embodiment, the roller brush assembly 100 may include a roller and a flexible cleaning member, wherein the flexible cleaning member is connected to the surface of the roller. When the cleaning device 10 performs a cleaning operation, as the roller rotates, the flexible cleaning member can slap the surface to be cleaned.

[0087] For example, the flexible cleaning member may be a rubber strip or a brush, etc., which is not specifically limited in the embodiments of the present application.

[0088] The present application provides a cleaning device comprising a roller brush assembly and a device body. The device body comprises a roller brush cavity, the roller brush assembly being rotatably disposed within the roller brush cavity, the device body comprising a suction channel and a suction port connected to the suction channel, the suction port being located at the front end of the roller brush cavity along a first direction; a blocking rib is provided on one side of the roller brush cavity near the suction port, the blocking rib comprising a connecting groove connecting the roller brush cavity and the suction port. During the cleaning process, the suction port can first draw hair fibers and large particles of debris into the suction channel to prevent fibers and hair from becoming entangled in the rear roller brush assembly, while the roller brush assembly can rub and tap the surface to be cleaned, lifting dust and fine particles and allowing them to enter the suction port through the connecting groove, thereby achieving a good cleaning effect.

[0089] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some or all of the technical features therein. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present application.
