Description

Technical Field

[0001] This application relates to the field of cleaning devices, and more specifically to a cleaning device. Background Technology

[0002] In the cleaning devices of the related technologies, when the ground is uneven or there are steps, the shovel blade will not be in contact with the ground or will be blocked by the steps and unable to move normally; and when the garbage particles are large, the garbage cannot enter the garbage box through the gap between the cleaning roller and the dust inlet guide slope, which will block the dust inlet channel or jam the cleaning roller, causing the cleaning device to malfunction. Utility Model Content

[0003] The purpose of this application is to provide a cleaning device to solve the technical problems of poor obstacle crossing performance and easy blockage of the guide channel by garbage in related technologies.

[0004] In a first aspect, this application provides a cleaning device, comprising:

[0005] A housing that encloses and forms a receiving space;

[0006] A cleaning roller, which is disposed within the receiving space and rotatably connected to the housing;

[0007] A trash can, wherein the trash can is disposed within the receiving space and is located on one side of the cleaning roller; and

[0008] A shovel assembly is disposed within the receiving space and between the cleaning roller and the waste container. The shovel assembly is slidably connected to the housing and can reciprocate relative to the housing along a first direction, wherein the first direction has an angle with the cleaning surface.

[0009] The cleaning device provided in this application includes a housing, a cleaning roller, a waste container, and a shovel assembly. The housing encloses a receiving space, and the cleaning roller is disposed within the receiving space and rotatably connected to the housing. The waste container is disposed within the receiving space and on one side of the cleaning roller. The shovel assembly is disposed within the receiving space and between the cleaning roller and the waste container. The shovel assembly is slidably connected to the housing and can reciprocate relative to the housing along a first direction, wherein the first direction forms an angle with the cleaning surface. The shovels of the shovel assembly abut against the cleaning surface. When larger particles of waste are trapped between the cleaning roller and the shovels or guide members of the shovel assembly during the cleaning process, the rotation of the cleaning roller causes the waste to squeeze the shovels or guide members of the shovel assembly. The shovels or guide members of the shovel assembly are pushed and pushed backward, causing the shovel assembly to move along the first direction and increasing the size of the inlet channel between the shovels and the cleaning roller. This allows larger particles of waste to enter the waste container from the inlet channel and be collected, improving the waste recycling rate of the cleaning device. Furthermore, when the cleaning device encounters steps or other obstacles on the cleaning path, the blades of the blade assembly will be pushed and squeezed backward, so that the blade assembly moves along the first direction. The first direction has an angle with the cleaning surface. In other words, the blade assembly will move upward in the vertical direction so that the blades can cross steps, protrusions and other obstacles, improve the cleaning device's ability to overcome obstacles, and will not damage the cleaning surface.

[0010] The angle α between the first direction and the clean surface is in the range of 0° < α < 90°.

[0011] The cleaning device further includes an elastic element, one end of which is connected to the shovel assembly and the other end of which is connected to the side wall of the housing, for driving the shovel assembly to move in the opposite direction of the first direction.

[0012] The elastic element extends along the second direction, and the second direction and the first direction have an angle β, wherein β satisfies: 0° < β < 90°.

[0013] The shovel assembly has a first mating part on the side facing the housing, and the housing has a second mating part on the side facing the shovel assembly. One of the first mating part and the second mating part is a slider, and the other is a groove. The slider is disposed in the groove and can reciprocate relative to the groove along the first direction, so that the shovel assembly reciprocates relative to the housing along the first direction.

[0014] The housing is further provided with a fixing member on its side, and one end of the elastic member is sleeved on the outer periphery of the fixing member, and the other end is sleeved on the outer periphery of the slider.

[0015] The shovel assembly includes a guide member and a shovel blade connected in sequence. The guide member is located between the trash can and the cleaning roller and extends in the direction toward the cleaning surface. The shovel blade is located at the end of the guide member away from the trash can and is used to contact the cleaning surface.

[0016] The trash can includes a first sidewall, a second sidewall, a third sidewall, and a fourth sidewall connected end to end. The first sidewall, the second sidewall, the third sidewall, and the fourth sidewall enclose a receiving cavity for containing trash. The first sidewall is close to the shovel assembly. The height of the guide member relative to the side away from the cleaning surface is greater than the height of the first sidewall.

[0017] The guide member has a bent portion on the side away from the shovel bar, and the bent portion extends in a direction close to the first sidewall.

[0018] The cleaning device further includes a brush roller, which is disposed within the receiving space and rotatably connected to the housing. The brush roller is located on the side of the trash box away from the cleaning surface, and is used to sweep the trash on the cleaning roller into the trash box. Attached Figure Description

[0034] This application provides a cleaning device 100 to solve the technical problems in the related art where the cleaning device has poor obstacle crossing performance and is easily blocked by garbage in the inlet channel.

[0035] Specifically, the cleaning device 100 includes a housing 10, a cleaning roller 20, a dustbin 30, and a shovel assembly 40. The housing 10 encloses a receiving space. The cleaning roller 20 is disposed within the receiving space and rotatably connected to the housing 10. The dustbin 30 is disposed within the receiving space and is located on one side of the cleaning roller 20. The shovel assembly 40 is disposed within the receiving space and is located between the cleaning roller 20 and the dustbin 30. The shovel assembly 40 is slidably connected to the housing 10 and can reciprocate relative to the housing 10 along a first direction D1, wherein the first direction D1 forms an angle with the cleaning surface.

[0036] It is understood that the cleaning device 100 in this application embodiment can be, but is not limited to, floor cleaning tools such as cleaning machines, sweeping robots, and floor scrubbers.

[0037] In this embodiment, the cleaning device 100 includes a housing 10, which encloses a receiving cavity. The receiving cavity is used to house the cleaning roller 20, the trash can 30, the shovel assembly 40, and other structural components of the cleaning device 100, which are not further limited in this application.

[0038] It should be noted that the housing 10 is the basic structural component of the cleaning device 100. The housing 10 includes structural components such as the outer shell and the support frame, which are not limited in this application. The housing 10 is used to support other structures inside the cleaning device 100, and the housing 10 has a certain strength and rigidity to withstand external impacts, compression, and other forces, protecting the internal components of the cleaning device 100 from physical damage from the external environment. Furthermore, the housing 10 is used to enclose the cleaning components and other parts inside the cleaning device 100, preventing the intrusion of external substances such as dust and water, avoiding damage or performance degradation of these components due to external factors, and extending the service life and operational stability of the cleaning device 100.

[0039] It should be noted that the housing 10, as a basic structural component of the cleaning device 100, comprises components such as the outer shell and support frame. The specific structural form can be determined according to design requirements, and this application does not limit it. The main function of the housing 10 is to provide load-bearing support for other internal structures of the cleaning device 100. Simultaneously, its inherent strength and rigidity effectively resist external impacts, compression, and other mechanical forces, thereby constructing a physical protective barrier for internal components and preventing damage from the external environment. Furthermore, the housing 10, through its enclosed structural design, isolates the cleaning components and other internal core components from the external environment, effectively preventing the intrusion of dust, liquids, and other external substances, preventing performance degradation or damage to these components due to external factors, thereby improving the service life and operational stability of the cleaning device 100.

[0040] In this embodiment, the cleaning device 100 further includes a cleaning roller 20, which is disposed in the receiving cavity and rotatably connected to the housing 10. The cleaning roller 20 contacts a cleaning surface, such as the ground, by rotating and removing stains and dust from the cleaning surface through physical friction; at the same time, it can carry the debris on the cleaning surface into the cleaning device 100 through physical friction and adhesion, so that it can be collected and processed by other structural components inside the device.

[0041] In this embodiment, the cleaning device 100 also includes a waste container 30 and a shovel assembly 40. The shovel assembly 40 is disposed between the cleaning roller 20 and the waste container 30, and is spaced apart from the cleaning roller 20 to form a waste inlet channel. This inlet channel serves as a waste transport path, guiding the waste carried by the cleaning roller 20 into the interior of the cleaning device 100, where it is finally collected by the waste container 30.

[0042] Please refer to Figures 1 to 6 Furthermore, in this embodiment, the shovel assembly 40 includes a guide 41 and a shovel 42 connected in sequence. The guide 41 is located between the trash can 30 and the cleaning roller 20 and extends in the direction toward the cleaning surface. The shovel 42 is located at the end of the guide 41 away from the trash can 30 and is used to contact the cleaning surface.

[0043] The scraper assembly 40 is capable of reciprocating along a first direction D1. When the scraper assembly 40 moves along the first direction D1, the size of the inlet channel between the guide member 41 of the scraper assembly 40 and the cleaning roller 20 increases, and the scraper assembly 40 moves upward in the vertical direction. When the scraper assembly 40 moves in the opposite direction of the first direction D1, the size of the inlet channel between the guide member 41 of the scraper assembly 40 and the cleaning roller 20 decreases, and the scraper assembly 40 moves downward in the vertical direction.

[0044] Furthermore, the shovel 42 of the shovel assembly 40 abuts against the cleaning surface. When the shovel 42 of the shovel assembly 40 abuts against the cleaning surface, if large particles of waste become stuck between the cleaning roller 20 and the shovel 42 during the operation of the cleaning device 100, the rotation of the cleaning roller 20 will cause the waste to exert a squeezing force on the shovel 42. Under this thrust, the shovel 42 moves backward and drives the shovel assembly 40 to move along the first direction D1, thereby expanding the size of the guide channel between the guide member 41 and the cleaning roller 20, so that larger particles of waste can enter the waste box 30 from the guide channel and be collected, improving the waste recycling rate of the cleaning device 100. When the cleaning device 100 travels to obstacles such as steps, the shovel 42 is pushed backward by the obstacle, driving the shovel assembly 40 to move along the first direction D1 at a certain angle to the cleaning surface. This movement causes the shovel assembly 40 to move upward in the vertical direction, ensuring that the shovel 42 can smoothly cross obstacles, thereby enhancing the cleaning device 100's ability to overcome obstacles while avoiding mechanical damage to the cleaning surface.

[0045] Further, in this embodiment, the angle α between the first direction D1 and the cleaning surface is 45°. Optionally, in other embodiments, the range of the angle α between the first direction D1 and the cleaning surface is: 0° < α < 90°. For example, in other embodiments, the angle α between the first direction D1 and the cleaning surface can also be 10°, or 15°, or 20°, or 25°, or 30°, or 35°, or 40°, or 45°, or 50°, or 55°, or 60°, or 65°, or 70°, or 75°, or 80°, or 85°, or 90°, or other values ​​between 0° and 90°, and this application does not limit this.

[0046] In this assembly, the scraper 42 of the scraper assembly 40 is at least partially a flexible component. The material of the scraper 42 includes, but is not limited to, soft rubber. The scraper 42 can adapt to cleaning surfaces of different heights through its own deformation, ensuring that the scraper 42 and the cleaning surface remain in close contact. To enhance the contact effect, an initial pressure is preset between the scraper 42 and the cleaning surface. This pre-pressure ensures that the scraper 42 maintains close contact with the cleaning surface in the initial standby state of the cleaning device 100. When the cleaning device 100 enters the mobile operation state, the scraper assembly 40 is displaced along the first direction D1. At this time, the pre-pressure between the scraper 42 and the cleaning surface dynamically decreases, which can reduce contact friction and form a small gap with the cleaning surface when necessary, providing structural adaptability for the cleaning device 100 to cross obstacles.

[0047] The guide component 41, acting as a rigid support structure, provides stable mechanical support for the scraper 42, ensuring a preset contact pressure between the scraper 42 and the cleaning surface. This rigid-flexible structural design has significant advantages: on the one hand, the flexible material (such as soft rubber) of the scraper 42 allows it to conform to the micro-undulations of the cleaning surface, achieving a close fit and improving its stain-grabbing ability; on the other hand, the rigidity of the guide component 41 can effectively resist the impact force when crossing obstacles or the squeezing force of large particles of debris, preventing structural bending or deformation failure, thereby continuously maintaining the preset contact state between the scraper 42 and the cleaning surface and ensuring the stability of the cleaning performance of the cleaning device 100.

[0048] In terms of structural design, the guide component 41 adopts a concave bending structure. This geometry can guide and constrain the waste carried by the cleaning roller 20. Through the curved surface guidance, the waste moves along a specific trajectory towards the inlet channel, effectively reducing the probability of waste falling due to gravity or collision during transmission and improving waste collection efficiency. In terms of material selection, the guide component 41 can be made of rigid materials such as plastic and metal. Metal is suitable for high-load conditions and has excellent impact resistance; plastic combines lightweight and cost advantages, and can be selected specifically according to the usage scenario and performance requirements of the cleaning device 100.

[0049] The cleaning device 100 provided in this application includes a housing 10, a cleaning roller 20, a trash can 30, and a shovel assembly 40. The housing 10 encloses a receiving space, and the cleaning roller 20 is disposed within the receiving space and rotatably connected to the housing 10. The trash can 30 is disposed within the receiving space and is located on one side of the cleaning roller 20. The shovel assembly 40 is disposed within the receiving space and is located between the cleaning roller 20 and the trash can 30. The shovel assembly 40 is slidably connected to the housing 10 and can reciprocate relative to the housing 10 along a first direction D1, wherein the first direction D1 has an angle with the cleaning surface. The shovel 42 of the shovel assembly 40 abuts against the cleaning surface. When the cleaning device 100 is cleaning, if large particles of garbage are trapped between the cleaning roller 20 and the shovel 42 or guide member 41 of the shovel assembly 40, the rotation of the cleaning roller 20 causes the garbage to squeeze the shovel 42 or guide member 41 of the shovel assembly 40. The shovel 42 or guide member 41 of the shovel assembly 40 will be pushed and squeezed backward, so that the shovel assembly 40 moves along the first direction D1 and the size of the inlet channel between the shovel 42 and the cleaning roller 20 is increased, so that larger particles of garbage can enter the garbage box 30 from the inlet channel and be collected, thereby improving the garbage recycling rate of the cleaning device 100. Furthermore, when the cleaning device 100 encounters steps or other obstacles on the cleaning path, the shovel 42 of the trash box 30 will be pushed and squeezed backward, so that the shovel assembly 40 moves along the first direction D1. The first direction D1 has an angle with the cleaning surface. In other words, the shovel assembly 40 will move upward in the vertical direction so that the shovel 42 can cross steps, protrusions and other obstacles, improve the obstacle-crossing ability of the cleaning device 100, and will not damage the cleaning surface.

[0050] Please refer to Figures 1 to 6 In one embodiment, the cleaning device 100 further includes an elastic element 50, one end of which is connected to the shovel assembly 40 and the other end of which is connected to the side wall of the housing 10, for driving the shovel assembly 40 to move in the opposite direction of the first direction D1.

[0051] As an energy storage and transfer unit, the elastic element 50 possesses inherent elastic properties that enable it to undergo elastic deformation and store elastic potential energy. By applying a preload to the blade assembly 40, it provides a reset driving force for the blade assembly 40. Specifically, when the cleaning device 100 encounters a step obstacle or sucks in larger particles of waste, the blade assembly 40 moves along the first direction D1 under the action of external resistance. During this process, the elastic element 50 is forced to compress (or stretch), undergoes elastic deformation, and stores elastic potential energy, thereby providing a buffer space for the clearance movement of the blade assembly 40.

[0052] When an obstacle passes or large particles of waste enter the waste box 30 through the inlet channel, the elastic element 50 releases its stored elastic potential energy due to the elimination of the external load. It then generates a reverse thrust through its own deformation recovery, driving the shovel assembly 40 to move and reset in the opposite direction of the first direction D1. During this process, the pre-pressure between the shovel 42 and the cleaning surface gradually recovers as the shovel assembly 40 resets, ensuring that the shovel 42 re-adheres tightly against the cleaning surface, thus restoring the cleaning device 100 to its normal cleaning operation state.

[0053] Optionally, in this embodiment, the elastic element 50 is a cylindrical spring. In other embodiments, the elastic element 50 can also be a torsion spring, a leaf spring, a tower spring, or other elastic structural component; this application does not impose any limitations on this. Further, optionally, in this embodiment, the number of elastic elements 50 is two, and the two elastic elements 50 are respectively spaced apart on opposite sides of the housing 10. Having two elastic elements 50 can increase the reset speed of the shovel assembly 40, thereby improving the cleaning efficiency of the cleaning device 100. In other embodiments, the number of elastic elements 50 can also be one, three, four, or more than four; this application does not impose any limitations on this.

[0054] Please refer to Figures 1 to 6 In one embodiment, the elastic member 50 extends along a second direction, and the second direction and the first direction D1 have an included angle β, where β satisfies: 0° < β < 90°.

[0055] Further, in this embodiment, the angle α between the first direction D1 and the cleaning surface is 10°. Optionally, in other embodiments, the angle α between the first direction D1 and the second direction may also be 3°, 5°, 7°, 15°, 20°, 25°, 30°, 35°, 40°, 45°, 50°, 55°, 60°, 65°, 70°, 75°, 80°, 85°, 90°, or other values ​​between 0° and 90°, and this application does not limit this.

[0056] Please refer to Figures 1 to 6 In one embodiment, the shovel assembly 40 is provided with a first mating part 43 on the side facing the housing 10, and the housing 10 is provided with a second mating part 11 on the side facing the shovel assembly 40. One of the first mating part 43 and the second mating part 11 is a slider, and the other is a groove. The slider is disposed in the groove and can reciprocate relative to the groove along the first direction D1, so that the shovel assembly 40 reciprocates relative to the housing 10 along the first direction D1.

[0057] The groove provides precise path guidance for the sliding of the slider, ensuring that the blade assembly 40 can only move along the first direction D1 and its opposite direction, preventing the blade assembly 40 from deviating or wobbling during sliding. Furthermore, when the slider slides within the groove, it effectively transfers the weight of the blade assembly 40 to the housing 10, allowing the housing 10 to support the blade assembly 40. Simultaneously, the slider also provides lateral support to the groove, preventing the blade assembly 40 from tilting or falling off during sliding.

[0058] Furthermore, the slider is slightly smaller than the groove to ensure that it can slide freely within the groove. Additionally, the gap between the slider and the groove is small to prevent the shovel assembly 40 from wobbling during sliding, thus improving its stability.

[0059] In this application, the first mating part 43 is used as a slider and the second mating part 11 is used as a groove for illustration, which should not be construed as a limitation of this application.

[0060] Specifically, the shovel assembly 40 has a first side and a second side facing the side of the housing 10, which are arranged opposite to each other. Both the first and second sides are provided with sliders. Similarly, the housing 10 also has a third side and a fourth side, which are arranged opposite to each other. Both the third and fourth sides are provided with grooves. The first side corresponds to the third side, and the slider of the first side is located within the groove of the third side. The second side corresponds to the fourth side, and the slider of the second side is located within the groove of the fourth side. This allows both ends of the shovel assembly 40 to be slidably connected to the housing 10, thereby improving the sliding stability of the shovel assembly 40 and preventing it from detaching from the housing 10.

[0061] It should be noted that when there are multiple pairs of sliding pairs consisting of the sliding groove and the slider, each pair is parallel to each other so that the shovel assembly 40 can slide effectively relative to the housing 10. Specifically, if multiple sliding grooves are provided on the third and fourth sides of the housing 10, the multiple sliding grooves are parallel to each other, and the sliding grooves on the third side and the fourth side are also parallel to each other. Optionally, in this embodiment, there are two pairs of sliding pairs consisting of the slider on the first side and the sliding groove on the third side, and two pairs of sliding pairs consisting of the slider on the second side and the sliding groove on the fourth side. In other embodiments, the sliding pairs consisting of the slider on the first side and the sliding groove on the third side can be one pair, three pairs, four pairs, or more than four pairs, and the sliding pairs consisting of the slider on the second side and the sliding groove on the fourth side can be one pair, three pairs, four pairs, or more than four pairs. This application does not impose any restrictions on this.

[0062] Optionally, the slider may include, but is not limited to, structural components such as protrusions, shafts, and rollers that slide within a groove. Further, the slider may be an integral structure with the guide 41 of the shovel assembly 40, or the slider may be assembled onto the guide 41 of the shovel assembly 40; this application does not impose any limitations on this.

[0063] Optionally, the slide can be an integral structure with the housing 10, or the slide can be combined with other parts on the housing 10. The combination method can be fastening, threaded connection, etc., and this application does not limit this.

[0064] Furthermore, the side of the housing 10 is also provided with a fixing member 12, one end of the elastic member 50 is sleeved on the outer periphery of the fixing member 12, and the other end is sleeved on the outer periphery of the slider.

[0065] Please refer to Figures 1 to 6 Furthermore, the trash box 30 includes a first side wall 31, a second side wall, a third side wall, and a fourth side wall connected end to end in sequence. The first side wall 31, the second side wall, the third side wall, and the fourth side wall enclose a receiving cavity for containing trash. The first side wall 31 is close to the shovel assembly 40. The height of the guide member 41 on the side away from the cleaning surface is greater than the height of the first side wall 31.

[0066] The guide member 41 is positioned higher on the side facing away from the cleaning surface than the first sidewall 31. This height difference creates a flow-guiding slope that plays a crucial role in the cleaning process. When the waste carried by the cleaning roller 20 is conveyed to the waste container 30 through the inlet channel, the higher edge of the guide member 41 forms an upward blocking boundary, effectively suppressing upward splashing of waste due to inertia or collision, thus reducing the risk of spillage in physical space. Simultaneously, this height difference, combined with the geometry of the guide member 41, forms a sloping flow channel, allowing waste to slide more smoothly along a preset trajectory into the receiving cavity of the waste container 30 under the combined action of gravity and the rotational thrust of the cleaning roller 20, preventing accumulation or retention within the channel and significantly improving the efficiency and integrity of waste collection.

[0067] Furthermore, a bend 411 is provided on the side of the guide member 41 facing away from the shovel bar 42. This bend extends in an arc or zigzag shape along the direction towards the first sidewall 31, forming a guide surface at a specific angle. This structural design, through geometric optimization, constructs a secondary flow guiding mechanism on the waste transport path: on the one hand, the inward bending trajectory of the bend 411 can laterally constrain the moving waste, correcting its direction of movement to conform to the inlet of the receiving cavity of the waste box 30; on the other hand, the bend structure and the height difference of the guide member 41 create a synergistic effect, reducing unnecessary collisions between waste and the inner wall of the device through the double guiding boundary, and reducing the problem of transmission jamming caused by frictional resistance. Whether it is solid particles or fibrous debris, it can enter the receiving cavity more accurately under the guidance of the bend 411, avoiding collection failure caused by path deviation.

[0068] Please refer to Figures 1 to 6 Furthermore, the cleaning device 100 also includes a brush roller 60, which is disposed in the receiving space and rotatably connected to the housing 10. The brush roller 60 is located on the side of the trash box 30 away from the cleaning surface, and is used to sweep the trash on the cleaning roller 20 into the trash box 30.

[0069] Specifically, the brush roller 60 is positioned above the trash can 30. When rotating, the brush roller 60 abuts against the cleaning roller 20 and brushes away debris adhering to the outer surface of the cleaning roller 20 into the trash can 30. Specifically, after the cleaning roller 20 has cleaned the surface, larger debris such as hair may remain attached. When the brush roller 60 rotates, it abuts against the cleaning roller 20 and brushes this debris into the trash can 30, preventing further adhesion of debris to the cleaning roller 20 and improving the waste collection efficiency of the cleaning device 100.
