Description

Technical Field

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

[0002] The sweeping robot cleans up the garbage on the ground by fitting the shovel bar to the ground. Currently, the shovel bar is fixed to the sweeping robot and is usually made of soft rubber. The deformation of the shovel bar itself is used to adapt to the ground of different heights so that the shovel bar and the ground are kept in close contact. However, the deformation of the soft rubber itself is not large enough to enable the sweeping robot to adapt to the ground environment with a large height difference. In addition, in order to make the shovel bar fit the ground more closely, there is a pre-pressure between the shovel bar and the ground, which makes the friction between the shovel bar and the ground larger, increases the moving resistance of the sweeping robot, and reduces the cleaning efficiency of the sweeping robot. Utility Model Content

[0003] In view of this, the present application provides a cleaning machine, which can adapt to cleaning surfaces with large height differences and has high cleaning efficiency.

[0004] The present application provides a cleaning machine, which includes: an outer shell, a cleaning roller and a shovel bar assembly, wherein the outer shell encloses a setting cavity; the cleaning roller is rotatably connected to the outer shell and is at least partially set in the setting cavity; the shovel bar assembly is located in the setting cavity and between the cleaning roller and the outer shell, the shovel bar assembly includes a first end and a second end that are set opposite to each other, the first end is rotatably connected to the outer shell, and the end of the second end away from the first end abuts against a cleaning surface, the shovel bar assembly has a first state and a second state relative to the cleaning roller, when the shovel bar assembly is in the first state, the second end is set close to the cleaning roller; when the shovel bar assembly is in the second state, the second end is set away from the cleaning roller.

[0005] Furthermore, the shovel bar assembly includes a rotating shaft, a shovel bar bracket and a shovel bar, the opposite ends of the rotating shaft are respectively connected to the outer shell, the shovel bar bracket has a first end, the first end is sleeved on the outer circumference of the rotating shaft, the shovel bar is arranged at the end of the shovel bar bracket away from the first end, and the end of the shovel bar away from the shovel bar bracket is the second end; when the cleaning machine is upright, the cleaning roller portion protrudes from the bottom surface of the outer shell.

[0006] Furthermore, the shovel bar bracket is bent toward a direction close to the cleaning roller, and when the shovel bar assembly is in a first state, the shovel bar bracket is at least partially arranged to fit the outer circumference of the cleaning roller.

[0007] Further, when the shovel bar assembly switches between the first state and the second state, in the height direction of the cleaning machine, the range of the difference h between the maximum distance and the minimum distance between the first end and the second end is: 0 < h ≤ 10 cm.

[0008] Further, when the shovel bar assembly is in the first state, the range of the angle α between the plane formed by the first end and the second end and the height direction of the cleaning machine is: 20° ≤ α ≤ 60°.

[0009] Further, the end of the shovel bar bracket away from the rotation axis has a mounting groove. The shovel bar includes a connected mounting portion and a soft rubber portion. The mounting portion is disposed in the mounting groove, and the soft rubber portion is located at one end of the mounting portion away from the shovel bar bracket.

[0010] Further, the shovel bar bracket and the mounting portion are rigid members, and the soft rubber portion is a flexible member.

[0011] Further, the mounting portion includes a connected first mounting sub-portion and a second mounting sub-portion. The mounting groove includes a first mounting sub-groove and a second mounting sub-groove that communicate with each other. The first mounting sub-portion is disposed in the first mounting sub-groove, and the second mounting sub-portion is disposed in the second mounting sub-groove. One end of the second mounting sub-portion away from the first mounting sub-portion is connected to the soft rubber portion, and the angle formed by the first mounting sub-portion and the second mounting sub-portion is an obtuse angle.

[0012] Further, the cleaning machine further includes a limiting member. The limiting member is disposed in the setting cavity and connected to the housing. The limiting member is located on the side of the shovel bar bracket away from the cleaning roller for limiting the shovel bar assembly. When the shovel bar assembly is in the second state, the shovel bar bracket abuts against the limiting member.

[0013] Further, the cleaning machine further includes a torsion spring member. The torsion spring member is disposed in the setting cavity. The torsion spring member includes a socket portion, a first torsion arm, and a second torsion arm. The first torsion arm and the second torsion arm are respectively connected to opposite ends of the socket portion. The socket portion is sleeved on the outer periphery of the rotation axis. The first torsion arm is connected to the shovel bar bracket, and the second torsion arm is connected to the housing.

[0014] In the present application, the scraper bar assembly is disposed on one side of the cleaning roller. During the movement of the cleaning machine, the scraper bar assembly shovels dust or garbage on the ground, and the cleaning roller cleans the dust or garbage on the ground. When the first end is rotatably connected to the housing, it drives the second end to be rotatably connected to the housing, so that the scraper bar assembly changes between a first state and a second state, that is, the second end changes between two states of approaching and moving away from the cleaning roller. When the first end is rotatably connected to the housing, in the height direction of the cleaning machine, the distance between the first end and the second end is also constantly changing. In other words, the height of the first end to the cleaning surface is constantly changing. In the present application, the end of the second end facing away from the first end abuts against the cleaning surface. Then, when the cleaning surface is uneven, such as having protrusions or depressions, the distance between the first end and the second end in the height direction of the cleaning machine can be adjusted by the rotational connection between the first end and the housing, so that the second end always abuts against the cleaning surface to clean the cleaning surface. Compared with the solution in which the scraper bar assembly is directly fixed to the housing, the scraper bar assembly of the present application is rotatably connected to the housing at the first end, so that the height of the first end to the cleaning surface is adjustable, and the end of the second end facing away from the first end always abuts against the cleaning surface, so that the cleaning machine can adapt to cleaning surfaces with large height differences and has a better cleaning effect on the ground. Specifically, when there is a protrusion on the cleaning surface, the distance between the first end and the second end in the height direction of the cleaning machine decreases, that is, the height of the first end to the cleaning surface decreases; when there is a depression on the cleaning surface, the distance between the first end and the second end in the height direction of the cleaning machine increases, that is, the height of the first end to the cleaning surface increases. Furthermore, in the present application, the scraper bar assembly has a certain gravity, and the second end droops under the action of gravity, and the second end has a good fit with the cleaning surface. Then, there is no need to directly set a large pre-pressure between the second end and the ground to adapt to the cleaning surface with a height difference. The abutting effect between the second end and the cleaning surface is within a reasonable range, which can not only ensure the cleaning of the cleaning surface, but also avoid excessive friction between the second end and the cleaning surface, which increases the forward resistance of the cleaning machine, and is beneficial to improving the cleaning efficiency of the cleaning machine.

Detailed implementation manners

[0027] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0028] The terms "first", "second", etc. in the description, claims and the above-mentioned drawings of this application are used to distinguish different objects, rather than to describe a specific order. 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 device that includes a series of steps or units is not limited to the listed steps or units, but may optionally further include steps or units not listed, or may optionally further include other steps or units inherent to these processes, methods, products or devices.

[0029] Reference to "embodiment" or "embodiment mode" in this context means that a particular feature, structure or characteristic described in connection with the embodiment or embodiment mode may be included in at least one embodiment of this application. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0030] The cleaning machine sweeps the garbage on the ground by means of a scraping strip fitting the ground. Currently, the scraping strip is fixedly arranged on the cleaning machine and is usually made of soft rubber. The deformation amount of the scraping strip itself is used to adapt to the ground with different heights, so that the scraping strip keeps close contact with the ground. However, the deformation amount of the soft rubber itself is not large enough to enable the cleaning machine to adapt to the ground environment with a large height difference. In addition, in order to make the scraping strip fit the ground better, there is a pre-pressure between the scraping strip and the ground, which makes the friction force between the scraping strip and the ground larger, increases the traveling resistance of the cleaning machine, and reduces the cleaning efficiency of the cleaning machine.

[0031] It can be understood that the meaning of there being a pre-pressure between the scraping strip and the ground is that there is a certain pre-applied pressure or force between the soft rubber and the ground to ensure close contact or fixation between the two. In some embodiments, in order to adapt to the ground with a height difference, the extrusion deformation amount of the soft rubber is large, and the ground is extruded through the extrusion deformation of the soft rubber, so that when encountering a lower ground, the soft rubber can still resist the ground. However, correspondingly, when encountering a higher ground, the extrusion deformation amount of the soft rubber is even larger, increasing the traveling resistance of the cleaning machine.

[0032] Please refer to Figures 1 to 3, this application provides a cleaning machine 100, which includes: a housing 110, a cleaning roller 120, and a scraping bar assembly 130. The housing 110 encloses a setting cavity 111; the cleaning roller 120 is rotatably connected to the housing 110 and at least partially disposed in the setting cavity 111; the scraping bar assembly 130 is located in the setting cavity 111 and between the cleaning roller 120 and the housing 110. The scraping bar assembly 130 includes a first end 131 and a second end 132 disposed opposite to each other. The first end 131 is rotatably connected to the housing 110, and the end of the second end 132 facing away from the first end 131 abuts against a cleaning surface 200; the scraping bar assembly 130 has a first state and a second state relative to the cleaning roller 120. When the scraping bar assembly 130 is in the first state, the second end 132 is disposed close to the cleaning roller 120; when the scraping bar assembly 130 is in the second state, the second end 132 is disposed away from the cleaning roller 120.

[0033] It can be understood that the cleaning machine 100 of the embodiment of this application can be, but is not limited to, a floor cleaning tool such as a sweeping robot or a floor washer.

[0034] Among them, in Figure 1 the embodiment, the scraping bar assembly 130 is in the first state; in Figure 2 the embodiment, the scraping bar assembly 130 is in the second state; in Figure 3 the embodiment, the scraping bar assembly 130 is between the first state and the second state.

[0035] It can be understood that during the transition of the scraping bar assembly 130 between the first state and the second state, the end of the second end 132 facing away from the first end 131 abuts against the cleaning surface 200.

[0036] It can be understood that the cleaning surface 200 is the surface that the cleaning roller 120 approaches and the second end 132 abuts against when the cleaning machine 100 is upright.

[0037] In this embodiment, the shovel bar assembly 130 is disposed on one side of the cleaning roller 120. During the movement of the cleaning machine 100, the shovel bar assembly 130 shovels away dust or garbage on the ground, and the cleaning roller 120 cleans the dust or garbage on the ground. When the first end 131 is rotatably connected to the housing 110, the second end 132 is driven to be rotatably connected to the housing 110, so that the shovel bar assembly 130 is transformed between the first state and the second state, that is, the second end 132 is transformed between the two states of being close to the cleaning roller 120 and being away from the cleaning roller 120. When the first end 131 is rotatably connected to the housing 110, the distance between the first end 131 and the second end 132 is constantly changing along the height direction of the cleaning machine 100. In other words, the height from the first end 131 to the cleaning surface 200 is constantly changing. In this embodiment, the end of the second end 132 away from the first end 131 abuts against the cleaning surface 200. When the cleaning surface 200 is uneven, such as having protrusions or depressions, the first end 131 can be connected to the housing 110 by rotation, so that the distance between the first end 131 and the second end 132 in the height direction of the cleaning machine 100 is adjusted, so that the second end 132 always abuts against the cleaning surface 200 to clean the cleaning surface 200. Compared with the solution in which the shovel bar assembly 130 is directly fixed to the housing 110, the shovel bar assembly 130 of the embodiment of the present application is connected to the housing 110 by rotation through the first end 131, so that the height from the first end 131 to the cleaning surface 200 is adjustable, and the end of the second end 132 away from the first end 131 always abuts against the cleaning surface 200, so that the cleaning machine 100 can adapt to the cleaning surface 200 with a large height difference, and has a better cleaning effect on the ground. Specifically, when the cleaning surface 200 has a bulge, the distance between the first end 131 and the second end 132 in the height direction of the cleaning machine 100 is reduced, that is, the height from the first end 131 to the cleaning surface 200 is reduced; when the cleaning surface 200 has a depression, the distance between the first end 131 and the second end 132 in the height direction of the cleaning machine 100 is increased, that is, the height from the first end 131 to the cleaning surface 200 is increased. Furthermore, in the embodiment of the present application, the shovel bar assembly 130 has a certain gravity, and the second end 132 droops under the action of gravity. The second end 132 has a good fit with the cleaning surface 200, so there is no need to directly set a large pre-pressure between the second end 132 and the ground to adapt to the cleaning surface 200 with a height difference. The abutment between the second end 132 and the cleaning surface 200 is within a reasonable range, which can not only ensure the cleaning of the cleaning surface 200, but also avoid excessive friction between the second end 132 and the cleaning surface 200 to increase the forward resistance of the cleaning machine 100, which is beneficial to improving the cleaning efficiency of the cleaning machine 100.

[0038] Optionally, the cleaning surface 200 is a ground surface, a tabletop, etc.

[0039] Please refer to Figure 4 and Figure 5 , in some embodiments, the shovel bar assembly 130 includes a rotating shaft 133, a shovel bar bracket 134 and a shovel bar 135. Opposite ends of the rotating shaft 133 are respectively connected to the housing 110. The shovel bar bracket 134 has the first end 131, and the first end 131 is sleeved on the outer periphery of the rotating shaft 133. The shovel bar 135 is disposed at an end of the shovel bar bracket 134 away from the first end 131. An end of the shovel bar 135 away from the shovel bar bracket 134 is the second end 132; when the cleaning machine 100 is upright, a part of the cleaning roller 120 protrudes from the bottom surface of the housing 110.

[0040] It can be understood that when the cleaning machine 100 is upright, that is, when the cleaning machine 100 is working normally, an end of the cleaning roller 120 protruding from the bottom surface contacts the cleaning surface 200.

[0041] In this embodiment, opposite ends of the rotating shaft 133 are respectively connected to the housing 110. The first end 131 of the shovel bar bracket 134 is rotatably sleeved on the outer periphery of the rotating shaft 133. The shovel bar 135 is disposed at an end of the shovel bar bracket 134 away from the first end 131. Then when the first end 131 rotates relative to the rotating shaft 133 in a direction close to the cleaning roller 120 or away from the cleaning roller 120, it will drive the shovel bar 135 to rotate in a direction close to the cleaning roller 120 or away from the cleaning roller 120, so as to realize the transformation of the shovel bar assembly 130 between the first state and the second state. When the cleaning machine 100 is upright, a part of the cleaning roller 120 protrudes from the bottom surface of the housing 110. The shovel bar 135 shovels the garbage or dust on the cleaning surface 200. During the rotation of the cleaning roller 120, the part of it protruding from the housing 110 cleans the garbage or dust on the cleaning surface 200. When the shovel bar assembly 130 transforms between the first state and the second state, the second end 132 of the shovel bar 135 always abuts against the cleaning surface 200 to shovel the dust or garbage on the cleaning surface 200. During the rotation of the first end 131 of the shovel bar bracket 134 relative to the rotating shaft 133, it drives the shovel bar 135 to rotate relative to the rotating shaft 133, so as to change the distance between the first end 131 and the second end 132 of the shovel bar assembly 130 in the height direction of the cleaning machine 100, so that when the cleaning surface 200 is uneven, the second end 132 can always abut against the cleaning surface 200, improving the use performance of the cleaning machine 100.

[0042] Optionally, in some embodiments, the rotation axis 133 is fixedly disposed on the housing 110, and the first end 131 is rotatably sleeved on the outer periphery of the rotation axis 133. When the first end 131 rotates relative to the rotation axis 133, the rotational connection between the first end 131 and the housing 110 is achieved. In some other embodiments, the rotation axis 133 is rotatably connected to the housing 110, and the first end 131 is fixedly sleeved on the outer periphery of the rotation axis 133. When the rotation axis 133 rotates relative to the housing 110, the first end 131 is driven to rotate relative to the housing 110 to achieve the rotational connection between the first end 131 and the housing 110.

[0043] Optionally, in some embodiments, the opposite ends of the rotation axis 133 are fixedly disposed on the housing 110; in some other embodiments, the opposite ends of the rotation axis 133 penetrate through the housing 110; in still some other embodiments, the opposite ends of the rotation axis 133 are clamped between the housing 110.

[0044] Optionally, in some embodiments, the cleaning roller 120 is cylindrical, and the scraper bar bracket 134 is an arc-shaped structure.

[0045] In some embodiments, the scraper bar bracket 134 is bent towards the direction close to the cleaning roller 120. When the scraper bar assembly 130 is in the first state, at least a part of the scraper bar bracket 134 is arranged in a manner that fits the outer periphery of the cleaning roller 120.

[0046] In this embodiment, the scraper bar bracket 134 is an arc-shaped structure and the scraper bar bracket 134 is bent towards the direction close to the cleaning roller 120, such that when the scraper bar bracket 134 is in the first state, at least a part of the scraper bar bracket 134 is arranged in a manner that fits the outer periphery of the cleaning roller 120. The cleaning roller 120 plays a certain limiting role on the scraper bar bracket 134, which can prevent the first end 131 from continuing to rotate towards the direction close to the cleaning roller 120 relative to the rotation axis 133, so as to limit the rotation angle of the first end 131 relative to the housing 110 within a certain range, ensuring that the end of the second end 132 departing from the first end 131 can always abut against the cleaning surface 200, thereby enabling the cleaning machine 100 to have a better cleaning effect. In addition, the arc-shaped scraper bar bracket 134 has a higher degree of fit with the cleaning roller 120, which can prevent the cleaning roller 120 and the scraper bar bracket 134 from interfering with each other and avoid mutual wear between the cleaning roller 120 and the scraper bar bracket 134, thus being beneficial to extending the service life of the cleaning machine 100.

[0047] Optionally, in some embodiments, the cleaning roller 120 is coaxially arranged with the scraper bar bracket 134. In other words, the scraper bar bracket 134 is arranged around the outer periphery of the cleaning roller 120.

[0048] Please refer to Figure 6 , in some embodiments, when the scraper bar assembly 130 switches between the first state and the second state, along the height direction of the cleaning machine 100, the range of the difference h between the maximum distance and the minimum distance of the first end 131 and the second end 132 is: 0 < h ≤ 10 cm.

[0049] Specifically, the value of the difference h between the maximum distance and the minimum distance of the first end 131 and the second end 132 can be, but is not limited to, 0.5 cm, 2 cm, 3 cm, 4 cm, 5 cm, 6 cm, 7 cm, 8 cm, 9 cm, 10 cm, etc.

[0050] In Figure 6 the embodiment, the positions of the scraper bar assembly 130 in the first state and the second state are simulated respectively to facilitate marking the value of h, which should not be understood as the cleaning machine 100 having two scraper bar assemblies 130.

[0051] It can be understood that when the included angle between the plane formed by the first end 131 and the second end 132 and the height direction of the cleaning machine 100 is the smallest, the distance between the first end 131 and the second end 132 is the maximum distance.

[0052] It can be understood that when the included angle between the plane formed by the first end 131 and the second end 132 and the height direction of the cleaning machine 100 is the largest, the distance between the first end 131 and the second end 132 is the minimum distance.

[0053] In this embodiment, when the shovel bar assembly 130 switches between the first state and the second state, the first end 131 rotates relative to the rotating shaft 133 in a direction away from the cleaning roller 120, the second end 132 changes from a position close to the cleaning roller 120 to a position away from the cleaning roller 120, and the distance between the first end 131 and the second end 132 in the height direction of the cleaning machine 100 is also continuously adjusted. In this embodiment, during the process of the shovel bar assembly 130 switching between the first state and the second state, the difference between the maximum distance and the minimum distance of the first end 131 and the second end 132 is the height difference range of the cleaning surface 200 that the cleaning machine 100 can adapt to. When the range of the difference h between the maximum distance and the minimum distance of the first end 131 and the second end 132 is: 0 < h ≤ 10 cm, the cleaning machine 100 can adapt to a relatively large height difference of the cleaning surface 200, improving the performance of the cleaning machine 100. In addition, the end of the first end 131 facing away from the second end 132 can not only have a good degree of fitting with the cleaning surface 200, so that the cleaning machine 100 has a good cleaning effect, but also avoid excessive pressure between the first end 131 and the cleaning surface 200, which increases the traveling resistance of the cleaning machine 100, making the cleaning machine 100 have both a good cleaning effect and a high cleaning efficiency. When the difference h between the maximum distance and the minimum distance of the first end 131 and the second end 132 is too large, when the first end 131 and the second end 132 are at the maximum distance in the height direction of the cleaning machine 100, it is difficult to ensure that the end of the first end 131 facing away from the second end 132 abuts against the cleaning surface 200, resulting in a poor degree of fitting between the shovel bar 135 and the cleaning surface 200 and reducing the cleaning effect of the cleaning machine 100. When the first end 131 and the second end 132 are at the minimum distance in the height direction of the cleaning machine 100, the pressure of the end of the first end 131 facing away from the second end 132 against the cleaning surface 200 may be too large, thereby increasing the traveling resistance of the cleaning machine 100 and reducing the cleaning efficiency of the cleaning machine 100. When the difference h between the maximum distance and the minimum distance of the first end 131 and the second end 132 is too small, the height difference of the cleaning surface 200 that the cleaning machine 100 can adapt to is too small, reducing the performance of the cleaning machine 100.

[0054] Please refer to Figure 7 , in some embodiments, when the shovel bar assembly 130 is in the first state, the range of the angle α between the plane formed by the first end 131 and the second end 132 and the height direction of the cleaning machine 100 is: 20° ≤ α ≤ 60°.

[0055] Specifically, the value of the included angle α between the plane formed by the first end 131 and the second end 132 and the height direction of the cleaning machine 100 can be, but is not limited to, 20°, 23°, 26°, 30°, 35°, 38°, 40°, 42°, 50°, 54°, 57°, 59°, 60°, etc.

[0056] In this embodiment, when the shovel bar assembly 130 is in the first state, the included angle between the plane formed by the first end 131 and the second end 132 and the height direction of the cleaning machine 100 is greater than the included angle between the plane formed by the first end 131 and the second end 132 and the height direction of the cleaning machine 100 when the shovel bar assembly 130 is in the second state. When the shovel bar assembly 130 is in the first state, the included angle between the plane formed by the first end 131 and the second end 132 and the height direction of the cleaning machine 100 can represent the maximum angle of rotation of the first end 131 relative to the rotation axis 133. That is, at this time, the distance between the first end 131 and the second end 132 in the height direction of the cleaning machine 100 is the minimum distance to adapt to the cleaning surface 200 with a higher height. When the range of the included angle α between the plane formed by the first end 131 and the second end 132 and the height direction of the cleaning machine 100 is 20° ≤ α ≤ 60°, the angle by which the first end 131 can rotate relative to the rotation axis 133 is within a reasonable range. Correspondingly, the adjustment range of the distance between the first end 131 and the second end 132 in the height direction of the cleaning machine 100 is reasonable. On the one hand, it can make the cleaning machine 100 adapt to the cleaning surface 200 with a large height difference. On the other hand, it can make the end of the second end 132 facing away from the first end 131 have a more appropriate adhesion force to the ground, so that the cleaning machine 100 has better use performance, cleaning effect, and higher cleaning efficiency. When the value of α is too large, the angle by which the first end 131 can rotate relative to the rotation axis 133 is too large. Correspondingly, the adjustment range of the distance between the first end 131 and the second end 132 in the height direction of the cleaning machine 100 is too large. Although it can make the cleaning machine 100 adapt to the cleaning surface 200 with a large height difference. However, it is difficult to ensure that the degree of adhesion of the end of the second end 132 facing away from the first end 131 to the cleaning surface 200 is within a reasonable range, thereby reducing the cleaning effect of the cleaning machine 100. When the value of α is too small, the angle by which the first end 131 can rotate relative to the rotation axis 133 is too small. Correspondingly, the adjustment range of the distance between the first end 131 and the second end 132 in the height direction of the cleaning machine 100 is too small, that is, the height difference of the cleaning surface 200 that the cleaning machine 100 can adapt to is too small, reducing the use performance of the cleaning machine 100.

[0057] In some embodiments, an end of the blade support 134 facing away from the rotation axis 133 has a mounting groove 1341. The blade 135 includes a connected mounting portion 1351 and a soft rubber portion 1352. The mounting portion 1351 is disposed in the mounting groove 1341, and the soft rubber portion 1352 is located at an end of the mounting portion 1351 facing away from the blade support 134.

[0058] In this embodiment, an end of the blade support 134 facing away from the rotation axis 133 has a mounting groove 1341 for mounting the blade 135. The mounting groove 1341 facilitates the installation and replacement of the blade 135 to improve the performance of the blade assembly 130. Among them, the blade 135 includes a mounting portion 1351 and a soft rubber portion 1352. The mounting portion 1351 is disposed in the mounting groove 1341 to assemble the blade support 134 and the soft rubber portion 1352 into an integral structure to improve the overall performance of the cleaning machine 100. The soft rubber portion 1352 is located at an end of the mounting portion 1351 facing away from the blade support 134. The soft rubber portion 1352 is the second end 132. When the cleaning machine 100 is upright, the soft rubber portion 1352 is disposed in contact with the cleaning surface 200, and the soft rubber portion 1352 has a certain deformation ability and sags under the action of gravity so that the adhesion force between the soft rubber portion 1352 and the cleaning surface 200 is within a reasonable range, which is beneficial to improving the cleaning effect of the cleaning machine 100. Furthermore, the friction between the soft rubber portion 1352 and the cleaning surface 200 is small, which is beneficial to reducing the traveling resistance of the cleaning machine 100, thereby improving the cleaning efficiency of the cleaning machine 100.

[0059] In some embodiments, the blade support 134 and the mounting portion 1351 are rigid members, and the soft rubber portion 1352 is a flexible member.

[0060] In this embodiment, the blade support 134 and the mounting portion 1351 are rigid members, and the soft rubber portion 1352 is a flexible member. The blade support 134 and the mounting portion 1351 provide rigid support for the soft rubber portion 1352. When the blade assembly 130 switches between the first state and the second state, the soft rubber portion 1352 is a flexible member and can have a good fitting effect with the cleaning surface 200. The blade support 134 and the mounting portion 1351 are rigid members and can avoid bending during the rotation relative to the rotation axis 133, thereby ensuring the fitting of the soft rubber portion 1352 to the cleaning surface 200, which is beneficial to improving the performance of the cleaning machine 100.

[0061] It is understandable that the second end 132 of the shovel bar 135 is a soft rubber portion 1352, and the cleaning roller 120 also has a certain flexibility. When the cleaning machine is upright, under the action of gravity, the soft rubber portion 1352 undergoes elastic deformation, and the cleaning roller 120 and the soft rubber portion 1352 both contact and abut the cleaning surface 200.

[0062] See also Figure 8 In some embodiments, the mounting portion 1351 includes a first mounting sub-portion 1353 and a second mounting sub-portion 1354 that are connected to each other, the mounting groove 1341 includes a first mounting sub-portion 1342 and a second mounting sub-portion 1343 that are connected to each other, the first mounting sub-portion 1353 is arranged in the first mounting sub-portion 1342, the second mounting sub-portion 1354 is arranged in the second mounting sub-portion 1343, and the end of the second mounting sub-portion 1354 that is away from the first mounting sub-portion 1353 is connected to the soft rubber portion 1352, and the angle formed by the first mounting sub-portion 1353 and the second mounting sub-portion 1354 is an obtuse angle.

[0063] It can be understood that, in the shovel strip 135 , the first mounting sub-portion 1353 , the second mounting sub-portion 1354 and the soft rubber portion 1352 are connected in sequence.

[0064] It can be understood that the first mounting sub-portion 1353 and the second mounting sub-portion 1354 are connected by bending.

[0065] In this embodiment, the first mounting sub - part 1353 is disposed in the first mounting sub - slot 1342, and the second mounting sub - part 1354 is disposed in the second mounting sub - slot 1343. The first mounting sub - part 1353 and the second mounting sub - part 1354 are bent and connected so that the mounting part 1351 can be stably disposed in the mounting slot 1341 to prevent the mounting part 1351 from falling out of the mounting slot 1341 during the use of the cleaning machine 100. When the included angle formed by the first mounting sub - part 1353 and the second mounting sub - part 1354 is an obtuse angle, the included angle between the first mounting sub - part 1353 and the second mounting sub - part 1354 is within a reasonable range. On the one hand, it is convenient to install the mounting part 1351 in the mounting slot 1341 for replacing the cleaning strip 135; on the other hand, during the switching process of the cleaning strip assembly 130 between the first state and the second state, the first mounting sub - part 1353 and the second mounting sub - part 1354 are bent and connected, which can prevent the second mounting sub - part 1354 from slipping out of the second mounting sub - slot 1343 driven by the soft rubber part 1352, so that the first mounting sub - part 1353 and the second mounting sub - part 1354 can be stably disposed in the mounting slot 1341, improving the assembly performance of the cleaning strip assembly 130. When the included angle formed by the first mounting sub - part 1353 and the second mounting sub - part 1354 is too large, that is, the included angle between the first mounting sub - part 1353 and the second mounting sub - part 1354 is a flat angle, during the use of the cleaning machine 100, when the cleaning strip assembly 130 switches between the first state and the second state, and the second end 132 always abuts against the cleaning surface 200, the friction between the second end 132 and the cleaning surface 200 may drive the mounting part 1351 to fall off from the mounting slot 1341, thus hindering the normal use of the cleaning machine 100 and reducing the use performance of the cleaning machine 100. When the included angle formed by the first mounting sub - part 1353 and the second mounting sub - part 1354 is too small, that is, the included angle formed by the first mounting sub - part 1353 and the second mounting sub - part 1354 is an acute angle or a right angle, it increases the difficulty of installing the mounting part 1351 in the mounting slot 1341, reduces the assembly difficulty of the cleaning strip assembly 130, and reduces the efficiency of replacing the cleaning strip 135.

[0066] In some embodiments, the cleaning machine 100 further includes a limiting member 140. The limiting member 140 is disposed in the setting cavity 111 and connected to the housing 110. The limiting member 140 is located on the side of the cleaning strip bracket 134 away from the cleaning roller 120 and is used to limit the cleaning strip assembly 130. When the cleaning strip assembly 130 is in the second state, the cleaning strip bracket 134 abuts against the limiting member 140.

[0067] Understandably, the cleaning roller 120 and the limiting member 140 are respectively disposed on opposite sides of the scraping bar bracket 134.

[0068] In this embodiment, when the scraping bar assembly 130 is in the second state, the scraping bar bracket 134 abuts against the limiting member 140, and the limiting member 140 can limit the position of the scraping bar bracket 134 to prevent the first end 131 from further moving away from the cleaning roller 120 relative to the rotation axis 133, so that the rotation angle of the first end 131 relative to the housing 110 is limited within a reasonable range, ensuring that the end of the second end 132 facing away from the first end 131 can always abut against the cleaning surface 200, thereby enabling the cleaning machine 100 to have a better cleaning effect. In addition, it can prevent the scraping bar bracket 134 from interfering with other components in the cleaning machine 100, such as the trash box 160, etc., improving the overall performance of the cleaning machine 100.

[0069] Please refer to Figure 9 , in some embodiments, the cleaning machine 100 further includes a torsion spring member 150. The torsion spring member 150 is disposed in the setting cavity 111. The torsion spring member 150 includes a socket portion 151, a first torsion arm 152, and a second torsion arm 153. The first torsion arm 152 and the second torsion arm 153 are respectively connected to opposite ends of the socket portion 151. The socket portion 151 is sleeved on the outer periphery of the rotation axis 133. The first torsion arm 152 is connected to the scraping bar bracket 134, and the second torsion arm 153 is connected to the housing 110.

[0070] In this embodiment, the socket part 151 of the torsion spring member 150 is sleeved on the outer periphery of the rotating shaft 133. The first torsion arm 152 and the second torsion arm 153 are respectively connected to opposite ends of the socket part 151. When one of the first torsion arm 152 and the second torsion arm 153 moves, the included angle between the first torsion arm 152 and the second torsion arm 153 changes, so that the first torsion arm 152 and the second torsion arm 153 abut against each other. In this embodiment, the first torsion arm 152 is connected to the scraper bar bracket 134, and the second torsion arm 153 is connected to the housing 110. When the first end 131 of the scraper bar bracket 134 rotates relative to the rotating shaft 133, the included angle between the first torsion arm 152 and the second torsion arm 153 changes, and the first torsion arm 152 and the second torsion arm 153 abut against each other to drive the housing 110 to have a certain abutting force on the scraper bar bracket 134. The torsion spring member 150 increases the abutting effect of the scraper bar bracket 134 and the scraper bar 135 on the ground. In other words, under the action of the gravity of the scraper bar 135 and the torsion spring member 150, the second end 132 has a better degree of fitting with the ground, which can avoid a gap between the second end 132 and the cleaning surface 200, and is beneficial to further improving the cleaning effect of the cleaning machine 100.

[0071] Optionally, the cleaning machine 100 further includes a driving member (not shown in the figure). The driving member is disposed in the setting cavity 111 and is adjacent to the cleaning roller 120. The driving member is used to drive the cleaning roller 120 to rotate.

[0072] In this embodiment, the driving member provides power for the cleaning roller 120 to rotate the cleaning roller 120, so as to drive the cleaning machine 100 to clean the garbage or dust on the cleaning surface 200 during the forward movement.

[0073] Optionally, the cleaning machine 100 further includes a garbage box 160. The garbage box 160 is disposed in the setting cavity 111. The garbage box 160 is disposed on the side of the scraper bar assembly 130 away from the cleaning roller 120. The garbage box 160 is used to collect the garbage falling off from the cleaning roller 120.
