Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cleaning products, and particularly relates to a cleaning device. BACKGROUND

[0002] Cleaning devices such as mite removal devices, vacuum cleaners and sweeping robots are commonly used cleaning devices in families. Vacuum cleaners and sweeping robots can clean the ground, and mite removal devices can remove dust and worms on the surface of a bed mattress or leather.

[0003] In the related art, a cleaning device generally comprises a shell and a fan unit arranged in the shell. Air flow generated by the fan unit generates suction at the air suction port of the shell. A roller brush can be arranged at a position corresponding to the air suction port. The roller brush rolls on the 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 air suction port to achieve the cleaning function.

[0004] However, in the current cleaning device, the air suction port is only opposite to a small local area on the roller brush assembly. The suction at the position of the roller brush away from the air suction port is weak, and the hair is easily entangled at the position of the roller brush away from the air suction port during the cleaning process and cannot be sucked into the device. Utility model content

[0005] The present application provides a cleaning device to solve the technical problem that the hair is easily entangled at the position of the roller brush away from the air suction port during the cleaning process in the current cleaning device.

[0006] The present application provides a cleaning device, which comprises a roller brush assembly and a device main body. The device main body has a roller brush cavity, and the roller brush assembly is rotationally arranged in the roller brush cavity.

[0007] The device main body has an air suction channel and an air suction port in communication with the air suction channel. The air suction port is in communication with the roller brush cavity. The roller brush cavity extends along a first direction, and the air suction port is arranged along the first direction. The length of the air suction port in the first direction is greater than or equal to two-thirds of the length of the roller brush cavity in the first direction.

[0008] The cleaning device provided by the present application designs the air suction port as a long strip structure along the axial direction of the roller brush assembly, so that the air suction port in the larger area in the length direction of the roller brush can generate uniform and strong negative pressure suction on the roller brush assembly. In the rotating cleaning process, the hair fibers rolled up at different positions in the length direction of the roller brush assembly can be sucked into the device by the sufficient suction, and the probability of the hair fibers entangled on the roller brush assembly is reduced.

[0009] As an optional implementation, the air suction port is located at the rear side of the roller brush assembly along the cleaning direction of the cleaning device. The air suction direction of the air suction port is inclined relative to the horizontal direction to the bottom of the cleaning device.

[0010] With this configuration, when the roller brush assembly is cleaning, the suction direction of the air inlet is the same as or nearly the same as the direction in which the roller brush assembly picks up hair and dust in the cleaning direction. This reduces suction loss and ensures that the long, narrow air inlet has sufficient suction for the hair fibers rolled up by the roller brush assembly, preventing hair from getting tangled on the roller brush assembly.

[0011] As an optional implementation, the width of the air intake is D, where 2mm≤D≤10mm.

[0012] This design avoids both the narrowness of the air intake opening hindering the intake of large debris and the wideness of the air intake opening reducing suction power and affecting cleaning performance.

[0013] As an optional implementation, the depth of the air intake along its air intake direction is H, where H ≥ 5 mm.

[0014] This configuration ensures a stable airflow throughout the entire length of the air intake, thereby maintaining a uniform and stable negative pressure suction.

[0015] As an alternative implementation, the air intake extends in a straight line, or at least a portion of the air intake in the first direction extends in an arc.

[0016] With this configuration, the air inlet can continuously generate uniform and stable suction at all axial positions of the roller brush assembly.

[0017] As an optional implementation, the air inlet of the air intake has multiple air intake sections, which are spaced apart along a first direction.

[0018] This design can improve the structural strength of the air intake.

[0019] As an optional implementation, adjacent suction sections can be staggered in the width direction of the suction inlet.

[0020] This configuration increases the effective coverage area of ​​the negative pressure suction at the air intake in the width direction, resulting in better cleaning performance from the cleaning equipment.

[0021] As an optional implementation, the ends of adjacent suction sections that are close to each other have a gap in a first direction; or,

[0022] The ends of adjacent suction sections are flush with each other in the first direction; or...

[0023] The ends of adjacent suction sections that are close to each other have at least partially overlapping areas in the first direction.

[0024] This setup allows for different suction section arrangements to be designed based on the specific structure and distribution of the cleaning components on the roller brush assembly, ensuring good cleaning results in different scenarios.

[0025] As an optional implementation, the main body of the device may include a first housing, a second housing, a cover plate, and an air duct housing; the first housing is connected above the second housing and forms an installation cavity, the cover plate is connected to the side of the second housing away from the first housing and forms a roller brush cavity with the second housing; the air duct housing is disposed in the installation cavity.

[0026] The air duct housing is configured to form an air intake channel and an air intake port, and the second housing has a ventilation port that connects to the roller brush cavity, with the air intake port and the ventilation port being connected.

[0027] This design allows for the separate processing and shaping of the long, narrow structure of the air intake, reducing production difficulty and costs.

[0028] As an alternative implementation, the outlines of the air intake and the air vent are matched; one of the air intake and the air vent has a sealing part on its circumferential edge, and the other of the air intake and the air vent has a sealing groove on its circumferential edge, with the sealing part inserted into the sealing groove.

[0029] This design improves the sealing of the connection between the air inlet and the air intake channel, preventing air leakage and reducing the negative pressure suction.

[0030] This application provides a cleaning device, which includes a roller brush assembly and a device body. The device body has a roller brush cavity, and the roller brush assembly is rotatably disposed within the roller brush cavity. The device body has a suction channel and a suction port communicating with the suction channel, and the suction port is communicating with the roller brush cavity. The roller brush cavity extends along a first direction, and the suction port is disposed along the first direction. The length dimension of the suction port in the first direction is greater than or equal to two-thirds of the length of the roller brush cavity along the first direction, so that the suction port can generate uniform and strong negative pressure suction on the roller brush assembly in a larger area along the length direction of the roller brush. As a result, during the rotation cleaning process of the roller brush assembly, the fibers and hairs rolled up at different positions along its length direction can be sucked into the device with sufficient suction, reducing the probability of hair fibers getting tangled on the roller brush assembly.

[0031] In addition to the technical problems solved by the embodiments of this application, the technical features constituting the technical solutions, and the beneficial effects brought about by the technical features of these technical solutions described above, other technical problems that the cleaning equipment provided by this application can solve, other technical features included in the technical solutions, and the beneficial effects brought about by these technical features will be further described in detail in the specific embodiments.

Detailed Implementation

[0047] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, an indirect connection through an intermediate medium, or the internal communication between two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0048] In the description of this application, it should be understood that the terms "upper", "lower", "front", "back", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0049] The terms "first," "second," and "third" (if any) in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a particular order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented, for example, in orders other than those illustrated or described herein.

[0050] Furthermore, the terms “comprising” and “having”, and any variations thereof, are intended to cover non-exclusive inclusion, such as a process, method, system, product, or maintenance tool that includes a series of steps or units, which is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or maintenance tool.

[0051] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0052] Cleaning equipment typically includes a housing and a fan unit installed inside the housing. The airflow generated by the fan unit creates suction at the air inlet of the housing. A roller brush can be installed at the corresponding position of the air inlet. The roller brush rolls on the surface to be cleaned, picking up dust and hair, and the suction from the air inlet draws the dust and hair into the equipment, thus achieving the cleaning function.

[0053] However, in current cleaning equipment, the air inlet is only opposite to a small local area on the roller brush assembly. The suction power is weaker at the part of the roller brush away from the air inlet. During the cleaning process, hair is easy to get tangled in the part of the roller brush away from the air inlet and cannot be sucked into the equipment. Furthermore, as the roller brush rolls, the tangled hair will get more and more tightly wrapped towards both ends of the roller brush and cannot be sucked away. This also makes cleaning the roller brush time-consuming and laborious.

[0054] To address the aforementioned technical problems, this application provides a cleaning device. Through the structural design of the air intake on the cleaning device, the air intake has a stable and uniform suction force at different positions along the length of the roller brush. Hair fibers rolled up at different positions along the length of the roller brush can be sucked into the device under sufficient suction force, reducing the amount of hair entangled on the roller brush, improving cleaning efficiency, and making it easier to clean the roller brush after cleaning.

[0055] The following is an example illustrating the application scenarios of the cleaning equipment provided in the embodiments of this application.

[0056] The cleaning equipment provided in this application embodiment is a cleaning tool with a roller brush structure. Specifically, the product type of the cleaning equipment in this application embodiment may include, but is not limited to, mite removers, vacuum cleaners, sweeping machines, and robotic vacuum cleaners. Depending on the product type, the cleaning equipment provided in this application embodiment can be used to clean floors, clothes, bedding, sofas, furniture, etc. This application embodiment does not make any specific limitations on this.

[0057] Figure 1 This is a schematic diagram of the structure of the cleaning equipment provided in the embodiments of this application; Figure 2 for Figure 1 A cross-sectional view along the AA direction; Figure 3 for Figure 2 A partial schematic diagram of position B in the middle; Figure 4 Cross-sectional view of the air intake location in the cleaning equipment provided in the embodiments of this application. Figure 1 ; Figure 5 Cross-sectional view of the air intake location in the cleaning equipment provided in the embodiments of this application. Figure 2 .

[0058] See Figures 1 to 5As shown, this 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 201, and the roller brush assembly 100 is rotatably disposed in the roller brush cavity 201.

[0059] The main body of the device 200 has a suction channel 202 and a suction port 203 connected to the suction channel 202. The suction port 203 is connected to the roller brush cavity 201. The suction port 203 can generate negative pressure suction to suck up dust, hair fibers and other debris.

[0060] Understandably, when the cleaning equipment 10 is performing a cleaning operation, the side of the equipment body 200 connected to the roller brush assembly 100 faces the surface to be cleaned. The roller brush assembly 100 can contact the surface to be cleaned. As the equipment body 200 moves, the roller brush assembly 100 rolls on the surface to be cleaned. The roller brush assembly 100 can pick up dust, fibers, hair and other impurities on the surface to be cleaned, making it easier for the dust, fibers and hair and other impurities to be sucked into the equipment body 200 through the air intake 203.

[0061] In some embodiments, the roller brush cavity 201 extends along a first direction, and the air intake 203 is disposed along the first direction. The length of the air intake 203 in the first direction is greater than or equal to two-thirds of the length of the roller brush cavity 201 in the first direction.

[0062] The first direction is defined as the X direction, meaning the roller brush cavity 201 is positioned along the X direction, which is also the width direction of the cleaning device 10. For example, the axial direction of the roller brush assembly 100 can be parallel to the X direction. During cleaning operations, the cleaning device 10 can move back and forth along the Y direction, which is perpendicular to the X direction. The suction port 203 can be positioned behind the roller brush assembly 100 along the Y direction, allowing dust, hair, and other debris stirred up by the rotation of the roller brush assembly 100 to be more easily drawn into the suction port 203.

[0063] Understandably, to ensure that the cleaning device 10 has a large cleaning area, the axial dimension of the roller brush assembly 100 matches the axial dimension of the roller brush cavity 201. For example, the length of the roller brush assembly 100 in the X direction can be equal to or slightly less than the length of the roller brush cavity 201 in the X direction, while the length of the roller brush cavity 201 in the X direction can be approximately or slightly less than the width of the cleaning device 10, thus allowing the roller brush assembly 100 to have a large coverage area in the X direction.

[0064] For the air intake 203, the negative pressure suction is weaker at points farther away and stronger at points closer to it. Since the length of the air intake 203 in the X direction is greater than or equal to two-thirds of the length of the roller brush cavity 201 in the X direction, the air intake 203 can form a long, narrow strip structure, meaning its length in the X direction is much greater than its width. The negative pressure suction of the air intake 203 can have a larger effective coverage area in the X direction; the effective area of ​​the negative pressure suction is greater than the length of the air intake 203 in the X direction, allowing dust, hair, and other debris carried up by both ends of the roller brush assembly 100 to be sucked into the interior of the device body 200 by the air intake 203.

[0065] It should be noted that in the cleaning device 10 provided in this application embodiment, by designing the air inlet 203 as a long strip structure along the axial direction of the roller brush assembly 100, the negative pressure suction generated by the air inlet 203 on each position along the length of the roller brush assembly 100 is uniform and strong. As a result, during the rotation cleaning process of the roller brush assembly 100, the fibers and hairs rolled up at different positions along its length can be sucked into the device body 200 by a sufficiently large suction, reducing the probability of hair fibers getting tangled on the roller brush assembly 100.

[0066] The specific structure of the air intake 203 will be described in detail below.

[0067] Please continue to refer to Figures 1 to 5 In one possible implementation, the air intake 203 is located behind the roller brush assembly 100 along the cleaning direction of the cleaning device 10. The air intake direction of the air intake 203 is inclined towards the bottom of the cleaning device 10 relative to the horizontal direction. Dust and hair fibers carried by the roller brush assembly 100 are more easily drawn into the air intake 203 along the direction of airflow.

[0068] Understandably, when the roller brush assembly 100 is cleaning, the suction direction of the air inlet 203 is the same as or nearly the same as the direction in which the roller brush assembly 100 picks up hair and dust in the cleaning direction, reducing suction loss and ensuring that the elongated air inlet 203 has sufficient suction for the hair fibers rolled up by the roller brush assembly 100, preventing hair from getting tangled on the roller brush assembly 100.

[0069] In some embodiments, the width of the air intake 203 is D, where 2mm ≤ D ≤ 10mm. This controls the width of the air intake 203 within a reasonable range, preventing it from being too narrow and obstructing the intake of large debris, while also preventing it from being too wide and reducing suction power, thus affecting cleaning efficiency. In this embodiment, the air intake 203 provides uniform and strong suction at different positions in the X direction, ensuring that all dust, particles, and hair fibers can enter the suction channel 202 through the air intake 203.

[0070] For example, the width of the air intake 203 can be any value including but not limited to 2mm, 2.1mm, 3mm, 5mm, 7mm, 9mm, 9.9mm, 10mm, etc., and this application embodiment does not make any specific limitation on this.

[0071] It should be noted that the interior of the suction channel 202 can be a uniformly sized airflow channel to ensure good ventilation efficiency and facilitate docking with downstream components such as dust cups. The suction port 203 connects to the suction channel 202. Since the suction port 203 is relatively long, a gradually narrowing transition phase is required between it and the suction channel 202. In this embodiment, to ensure more uniform and powerful suction along the length of the suction port 203, the suction port 203 has a certain depth in the airflow intake direction. That is, within a certain distance in the airflow intake direction, the cross-sectional length of the suction port 203 remains constant or approximately constant. This prevents the suction force of the suction port 203 from becoming uneven and unstable due to changes in the ventilation area.

[0072] In some embodiments, the depth of the air intake 203 along its suction direction is H, where H ≥ 5 mm. This allows the air intake 203 to have a stable airflow along its entire length, thereby maintaining a uniform and stable negative pressure suction.

[0073] For example, the depth H of the air intake 203 along its air intake direction can be a specific value including but not limited to 5mm, 5.1mm, 6mm, 8mm, 10mm, 15mm, 20mm, etc., and this application embodiment does not make a specific limitation on this.

[0074] In this embodiment, the length of the air intake 203 along the X direction is greater than or equal to two-thirds of the length of the roller brush cavity 201 along the X direction. This means that the radiation range of the negative pressure suction of the air intake 203 can cover more than two-thirds of the length of the roller brush cavity 201. The specific length of the air intake 203 can be equal to two-thirds or three-quarters of the length of the roller brush cavity 201, or the length of the air intake 203 can be equal to the length of the roller brush cavity 201. This embodiment does not specifically limit this.

[0075] In this embodiment of the application, the air intake 203 being arranged along the first direction means that the air intake 203 has a general tendency to extend along the first direction, without limiting its specific posture to whether it is parallel to the X direction or has an angle with the X direction. The morphology and structure of the air intake 203 will be described below through different specific examples.

[0076] Figure 6 Schematic diagram of the structure of the air intake in the cleaning equipment provided in the embodiments of this application Figure 1 .

[0077] Please refer to Figure 6 and combined Figure 2 In one possible implementation, the air intake 203 extends along a straight line, with its long side parallel to the X-direction. This allows the air intake 203 to continuously generate uniform and stable suction at all axial positions of the roller brush assembly 100.

[0078] Figure 7 Schematic diagram of the structure of the air intake in the cleaning equipment provided in the embodiments of this application Figure 2 .

[0079] Please refer to Figure 7 and combined Figure 2 In another possible implementation, the air intake 203 extends along an arc in at least a portion of the first direction. For example, the middle portion of the air intake 203 may be recessed downwards, so that the area of ​​the air intake 203 corresponding to the middle portion of the roller brush assembly 100 is closer to the surface to be cleaned during the cleaning process, thereby making it easier for dust, hair fibers, and other debris to accumulate in the middle and be drawn into the air intake 203.

[0080] Figure 8 Schematic diagram of the structure of the air intake in the cleaning equipment provided in the embodiments of this application Figure 3 ; Figure 9 Schematic diagram of the structure of the air intake in the cleaning equipment provided in the embodiments of this application Figure 4 ; Figure 10 Schematic diagram of the structure of the air intake in the cleaning equipment provided in the embodiments of this application Figure 5 .

[0081] In some embodiments, the air inlet of the air inlet 203 has a plurality of air inlet sections 2031, which are spaced apart along a first direction, thereby improving the structural strength of the air inlet 203.

[0082] It is understandable that the partition wall between adjacent suction sections 2031 can support the suction port 203, making the elongated suction port 203 have a more stable structure during the suction process.

[0083] In some embodiments, adjacent suction sections 2031 may be staggered in the width direction of the suction port 203, thereby increasing the effective coverage area of ​​the negative pressure suction of the suction port 203 in the width direction of the suction port 203, so that the cleaning device 10 has a better cleaning effect.

[0084] For example, please refer to Figure 9 The adjacent suction sections 2031 have a gap at their closest ends in the first direction.

[0085] For example, please refer to Figure 10 The ends of adjacent suction sections 2031 that are close to each other are set flush with each other in the first direction.

[0086] For example, please refer to Figure 8 In this embodiment, the ends of adjacent suction sections 2031 that are close to each other have at least partially overlapping areas in the first direction. Different arrangement methods of the suction sections 2031 can be designed according to the specific structure and distribution of the cleaning components on the roller brush assembly 100 to ensure good cleaning performance in different scenarios.

[0087] In one possible implementation, the main body 200 may include a first housing 210, a second housing 220, a cover plate 230, and an air duct housing 240. The first housing 210 is connected above the second housing 220 and forms a mounting cavity 204. The cover plate 230 is connected to the side of the second housing 220 opposite to the first housing 210 and together with the second housing 220 forms a brush cavity 201. The air duct housing 240 is disposed within the mounting cavity 204.

[0088] The air duct housing 240 is configured to form an air intake channel 202 and an air intake port 203, and the second housing 220 has a vent 221 that communicates with the roller brush cavity 201, with the air intake port 203 connected to the vent 221.

[0089] It is understandable that the vent 221 is opened on the inner wall of the roller brush cavity 201, and the air intake 203 is formed by the air duct shell 240. The long strip structure of the air intake 203 can be processed and formed separately, reducing production difficulty and cost.

[0090] In some embodiments, the outlines of the air intake 203 and the ventilation vent 221 are matched. One of the air intake 203 and the ventilation vent 221 has a sealing portion 241 on its circumferential edge, and the other of the air intake 203 and the ventilation vent 221 has a sealing groove 222 on its circumferential edge. The sealing portion 241 is inserted into the sealing groove 222, thereby improving the sealing performance at the docking position of the air intake 203 and the air intake channel 202, and preventing airflow leakage that would reduce the negative pressure suction.

[0091] For example, the sealing part 241 and the sealing groove 222 can be fixed by ultrasonic welding to achieve a better sealing effect. Alternatively, a rubber sealing ring can be provided in the sealing groove 222, the sealing part 241 presses the sealing ring, and the air duct housing 240 is fixed to the first housing 210 or the second housing 220 by fasteners such as screws.

[0092] In some embodiments, the outer wall of the second housing 220 facing the bottom of the cleaning device 10 forms a roller brush cavity 201. When the first housing 210 and the second housing 220 are connected, they can be fixed by screw connection or ultrasonic welding. The connection position can be positioned by a double stop structure with a protrusion and a groove.

[0093] The specific structure of the roller brush assembly 100 is described in detail below.

[0094] Please refer to Figures 1 to 6 As an optional implementation, the roller brush assembly 100 may include a roller 110 and a flexible cleaning element 120, the flexible cleaning element 120 being connected to the surface of the roller 110. When the cleaning device 10 performs a cleaning operation, the flexible cleaning element 120 can tap the surface to be cleaned as the roller 110 rotates.

[0095] For example, the flexible cleaning element 120 can be one or a combination of adhesive strips, brushes, etc. For instance, the flexible cleaning element 120 can be an adhesive strip. When an adhesive is used as the flexible cleaning element 120, the adhesive strip can pat the surface to be cleaned, and hair will not get tangled on the adhesive strip. The hair carried by the adhesive strip is more easily sucked into the interior of the cleaning device 10 along the outer edge of the adhesive.

[0096] For example, multiple flexible cleaning elements 120 can be arranged in parallel and all extend along the axial direction of the roller 110. In this way, flexible cleaning elements 120 can contact the surface being cleaned in the axial direction of the roller brush assembly 100, thereby increasing the cleaning range.

[0097] For example, multiple flexible cleaning elements 120 extend spirally along the circumferential outer wall of the roller 110. In this way, as the roller brush assembly 100 rolls along the cleaning direction of the cleaning device 10, different positions of the flexible cleaning elements 120 in the extension direction can sequentially contact the surface to be cleaned as the roller brush assembly 100 rolls, without obstructing the negative pressure airflow of the suction port 203, thereby improving the suction efficiency of dust and hair.

[0098] It should be noted that the number of flexible cleaning parts 120 can be two, three, four, five or more, and this application embodiment does not specifically limit this.

[0099] This application provides a cleaning device, which includes a roller brush assembly and a device body. The device body has a roller brush cavity, and the roller brush assembly is rotatably disposed within the roller brush cavity. The device body has a suction channel and a suction port communicating with the suction channel, and the suction port is communicating with the roller brush cavity. The roller brush cavity extends along a first direction, and the suction port is disposed along the first direction. The length dimension of the suction port in the first direction is greater than or equal to two-thirds of the length of the roller brush cavity along the first direction, so that the suction port can generate uniform and strong negative pressure suction on the roller brush assembly in a larger area along the length direction of the roller brush. As a result, during the rotation cleaning process of the roller brush assembly, the fibers and hairs rolled up at different positions along its length direction can be sucked into the device with sufficient suction, reducing the probability of hair fibers getting tangled on the roller brush assembly.

[0100] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
