Description

Technical Field

[0001] The present application relates to the field of cleaning technology, and particularly to a cleaning device. Background Art

[0002] In family life, tedious housework takes up a large amount of time and energy, and cleaning devices have emerged under such circumstances. In existing cleaning devices, the cleaning mechanism is connected to the main body of the cleaning device in a swing rod manner. In the working state, under the action of gravity, the cleaning mechanism is in contact with the ground to be cleaned and the transmission inclined plane respectively, so as to clean the ground to be cleaned and cooperate with the transmission inclined plane to transfer the object to be cleaned into the storage box. However, due to the large support of the transmission inclined plane for the cleaning mechanism, this greatly affects the dynamic pressure of the cleaning mechanism on the ground to be cleaned, resulting in poor cleaning ability of the cleaning device and unable to meet the family cleaning needs. Content of the Utility Model

[0003] The present application provides a cleaning device, which includes a main frame and a cleaning mechanism. The main frame is provided with a first transmission inclined plane, and the cleaning mechanism is arranged on the front side of the first transmission inclined plane. The cleaning mechanism includes a cleaning belt and a roller mechanism. The roller mechanism includes a first roller, a second roller and a connecting rod assembly. The connecting rod assembly includes a first end and a second end arranged oppositely. The first roller is rotatably supported at the first end of the connecting rod assembly and can rotate around a first axis. The second roller is rotatably supported at the second end of the connecting rod assembly and can rotate around a second axis parallel to the first axis. The connecting rod assembly is rotatably supported on the main frame. The cleaning belt is annularly arranged around the peripheries of the first roller and the second roller, and in the working state, is pressed against the ground to be cleaned and the first transmission inclined plane by the gravity of the roller mechanism through the second roller; wherein, the main frame is provided with a wheel body, and the wheel body is used to define a support surface in contact with the ground to be cleaned. In a reference cross-section perpendicular to the support surface and parallel to the traveling direction of the cleaning device, there is a first connection line between the lower end and the upper end of the first transmission inclined plane. On the side of the first roller and / or the second roller facing the first transmission inclined plane, there is a common tangent line between the first roller and the second roller.

[0004] Advantages of the present application: The present application provides a cleaning device which includes a main frame and a cleaning mechanism. The main frame is provided with a first transmission inclined plane, and the cleaning mechanism is arranged on the front side of the first transmission inclined plane. The cleaning mechanism includes a cleaning belt and a roller mechanism. The roller mechanism includes a first roller, a second roller and a connecting rod assembly. The connecting rod assembly includes a first end and a second end arranged oppositely. The first roller is rotatably supported at the first end of the connecting rod assembly and can rotate around a first axis. The second roller is rotatably supported at the second end of the connecting rod assembly and can rotate around a second axis parallel to the first axis. The connecting rod assembly is rotatably supported on the main frame. The cleaning belt is annularly arranged around the peripheries of the first roller and the second roller, and in the working state, the second roller presses the cleaning belt against the ground to be cleaned and the first transmission inclined plane by the gravity of the roller mechanism. Wherein, the main frame is provided with a wheel body, and the wheel body is used to define a supporting surface in contact with the ground to be cleaned. In a reference section perpendicular to the supporting surface and parallel to the traveling direction of the cleaning device, there is a first connecting line between the lower end and the upper end of the first transmission inclined plane. On one side of the first roller and / or the second roller facing the first transmission inclined plane, there is a common tangent line between the first roller and the second roller. When the cleaning belt contacts the first transmission inclined plane without deformation, along the extending direction of the second roller towards the first roller, the common tangent line gradually moves away from the first connecting line. In this way, the whole cleaning mechanism is in a single cantilever structure, suspended on the equipment main body, so that the whole roller mechanism can press the cleaning belt against the ground to be cleaned and the transmission inclined plane under the action of its own gravity, so that the cleaning device does not need to be equipped with an additional acting mechanism to hold the cleaning belt on the ground to be cleaned and the transmission inclined plane, thereby effectively improving the cleaning efficiency and cleaning ability of the cleaning device while effectively simplifying the structure of the cleaning device. Moreover, when the cleaning belt contacts the first transmission inclined plane, along the extending direction of the second roller towards the first roller, setting the common tangent line to gradually move away from the first connecting line can make the common tangent line gradually move away from the first connecting line along the extending direction in the working state, and further make the first transmission inclined plane have at least three contact relationships with the cleaning belt in sequence, which are respectively "the first transmission inclined plane contacts the cleaning belt, interferes with the cleaning belt, and supports the cleaning belt to support the cleaning mechanism", "the first transmission inclined plane contacts the cleaning belt, and there is no interference or less interference with the cleaning belt, and the first transmission inclined plane does not play a supporting role or has a small supporting role on the cleaning belt", and "the first transmission inclined plane and the cleaning belt are indirectly contacted through the vibration action of the cleaning belt". In this way, the supporting effect of the first transmission inclined plane on the cleaning mechanism in the working state can be effectively reduced, so that on the premise of ensuring the dynamic pressure of the cleaning belt on the first transmission inclined plane, the first dynamic pressure of the cleaning belt on the ground to be cleaned can be effectively increased, and the cleaning ability of the cleaning device can be effectively improved while the transmission efficiency of the cleaning belt cooperating with the transmission inclined plane to transport the object to be cleaned can be effectively improved.

[0014] The following will further describe the present application in detail in combination with the accompanying drawings and embodiments. It should be specifically pointed out that the following embodiments are only used to illustrate the present application, but do not limit the scope of the present application. Similarly, the following embodiments are only some embodiments of the present application rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

[0015] When the present application mentions "embodiment", it means that the specific features, structures or characteristics described in combination with the embodiment can be included in at least one embodiment of the present application. Those skilled in the art explicitly and implicitly understand that the embodiments described in the present application can be combined with other embodiments.

[0016] This application provides a cleaning device 1, as Figure 1 and Figure 2 shown. The cleaning device 1 includes a device main body 20 and a cleaning mechanism 10. The device main body 20 is provided with a transmission inclined surface 23. In some embodiments, the device main body 20 is provided with a motion mechanism, such as a wheel body 30, etc., so that the cleaning device 1 as a whole can move on the ground 2 to be cleaned, such as the living room floor, the guest room floor, the kitchen floor and other areas to be cleaned. The cleaning mechanism 10 abuts against the ground 2 to be cleaned to perform cleaning work on the ground 2 to be cleaned, and the cleaning mechanism 10 also abuts against the front side of the transmission inclined surface 23 to cooperate with the transmission inclined surface 23 to transfer the garbage, stains and other objects to be cleaned on the ground to be cleaned to the rear side of the transmission inclined surface 23, such as into the storage box 40 at the rear side of the transmission inclined surface 23, so as to effectively simplify the overall structure of the cleaning device 1 while effectively improving the transmission efficiency of the cleaning device 1 for the garbage, stains and other objects to be cleaned. It should be noted that when the cleaning device 1 is placed on the ground 2 to be cleaned, the transmission inclined surface 23 is inclined relative to the ground 2 to be cleaned. Among them, the front side of the transmission inclined surface 23 is defined as the side with a larger inclination angle of the transmission inclined surface 23 relative to the ground 2 to be cleaned, and the rear side of the transmission inclined surface 23 is defined as the side with a smaller inclination angle of the transmission inclined surface 23 relative to the ground 2 to be cleaned.

[0017] Optionally, as Figure 2 shown, in some embodiments, the cleaning mechanism 10 includes a roller mechanism 15 and a cleaning belt 13 wound around the outer periphery of the roller mechanism 15. The device main body 20 is provided with a transmission inclined surface 23. The roller mechanism 15 is located on the front side of the transmission inclined surface 23. The cleaning belt 13 is pressed by the roller mechanism 15 on the transmission inclined surface 23 and the ground 2 to be cleaned, and moves relative to the transmission inclined surface 23 and the ground 2 to be cleaned under the drive of the roller mechanism 15 to transfer the garbage, stains and other objects to be cleaned on the ground 2 to be cleaned from the lower end of the transmission inclined surface to the upper end of the transmission inclined surface, which can effectively improve the functional diversity of the cleaning belt 13 and effectively simplify the structure of the cleaning device 1.

[0018] Further, in the working state (i.e., in the state where the cleaning device 1 cleans the ground 2 to be cleaned), the cleaning belt 13 has a first dynamic pressure on the ground 2 to be cleaned, so that the cleaning belt 13 can clean the ground 2 to be cleaned. And, in the working state, the cleaning belt 13 has a fourth dynamic pressure on the transmission inclined plane 23, so that the cleaning belt 13 can cooperate with the transmission inclined plane 23 more efficiently to transport the object to be cleaned into the storage box 40, thereby effectively improving the transmission efficiency of the cleaning belt 13 for the object to be cleaned. Among them, the first dynamic pressure is the dynamic pressure exerted by the cleaning belt 13 on the ground 2 to be cleaned under the support of the transmission inclined plane 23. The magnitude of the first dynamic pressure is directly related to factors such as the gravity of the cleaning mechanism 10, the dynamic pressure of the cleaning mechanism 10 on the transmission inclined plane 23 (i.e., the fourth dynamic pressure), and the dynamic force of the cleaning mechanism 10 on the equipment main body 20. Specifically, the force analysis of the cleaning mechanism 10 can be carried out through theoretical mechanics, which will not be elaborated in detail here.

[0019] Specifically, as Figure 2 shown, in this embodiment, the cleaning mechanism 10 is connected to the equipment main body 20 in a swing rod manner. In other words, the cleaning mechanism 10 can swing relative to the equipment main body 20 around the third axis z3. For example, in some embodiments, the cleaning mechanism 10 can be in a cantilever structure and be arranged on the equipment main body 20, so that the whole cleaning mechanism 10 has a tendency to swing around the third axis z3 towards the transmission inclined plane 23 under the action of its own gravity, so as to press the cleaning belt 13 against the ground 2 to be cleaned and the transmission inclined plane 23, thereby realizing the cleaning of the ground 2 to be cleaned.

[0020] Optionally, as Figure 2 shown, in some embodiments, the roller mechanism 15 includes a first roller 11, a second roller 12 and a connecting rod assembly 14. The connecting rod assembly 14 includes a first end and a second end arranged oppositely. The first roller 11 is rotatably supported at the first end of the connecting rod assembly 14 and can rotate around the first axis z1. The second roller 12 is rotatably supported at the second end of the connecting rod assembly 14 and can rotate around the second axis z2 parallel to the first axis z1. The connecting rod assembly 14 is rotatably supported on the equipment main body 20, so that the whole cleaning mechanism 10 is arranged on the equipment main body 20 in a swing rod manner. Among them, the first axis z1 is perpendicular to the traveling direction X1 of the cleaning device 1.

[0021] Optionally, as Figure 2As shown, in some embodiments, the first axis z1 is the central axis of the first roller 11, and the second axis z2 is the central axis of the second roller 12. Among them, the third axis z3 is the rotation axis of the link assembly 14 relative to the device main body 20. Among them, the third axis z3 can be arranged to coincide with the first axis z1. That is, while taking the first axis z1 as the rotation axis of the roller 11, it is also used as the third axis z3 of the cleaning mechanism 10, so that the cleaning mechanism 10 as a whole has a single cantilever structure. For example, the first end of the link assembly 14 is rotatably connected to the first roller 11 and is also rotatably connected to the device main body 20. In this way, the cleaning mechanism 10 as a whole has a single cantilever structure and is suspended on the device main body 20, so that the roller mechanism 15 as a whole can press the cleaning belt 13 against the ground 2 to be cleaned and the transmission slope 23 under the action of its own gravity.

[0022] In an alternative embodiment, the third axis z3 and the first axis z1 can also be parallel to each other.

[0023] In an alternative embodiment, the distance between the third axis z3 and the first axis zl is less than the radius of the first roller 11.

[0024] Optionally, as Figure 3 As shown, in some embodiments, the first axis z1, the second axis z2 and the third axis z3 are spaced apart from each other. Among them, the third axis z3 can be arranged to be parallel to the first axis z1, or the third axis z3 can also be arranged to form a certain angle with the first axis z1. For example, in some embodiments, the roller mechanism 15 further includes a connecting member 16. One end of the connecting member 16 is fixedly connected to the link assembly 14, and the other end of the connecting member 16 is rotatably connected to the device main body 20, so that the cleaning mechanism 10 as a whole is connected to the device main body 20 in a swing rod manner. In this way, the cleaning mechanism 10 as a whole has a single cantilever structure and is suspended on the device main body 20, so that the roller mechanism 15 as a whole can press the cleaning belt 13 against the ground 2 to be cleaned and the transmission slope 23 under the action of its own gravity.

[0025] Optionally, in some embodiments, the radial dimension of the first roller 11 is smaller than the radial dimension of the second roller 12, and the ratio of the radial dimensions of the first roller 11 and the second roller 12 is between 0.4 and 0.6.

[0026] For example, in some embodiments, the radial dimension of the first roller 11 is less than or equal to 22 mm. For example, the actual values less than or equal to 22 mm such as 22 mm, 21 mm, 20 mm, or 19 mm, etc. On the premise of meeting the structural strength, the structural dimension of the first roller 11 can be as small as possible, which is beneficial to the miniaturization of the cleaning device. And, in some embodiments, the radial dimension of the second roller 12 is between 48 mm and 77 mm. For example, the actual values between 48 mm and 77 mm such as 48 mm, 49 mm, 50 mm, 55 mm, or 77 mm, etc. In this way, the cleaning device 1 can clean the object to be cleaned with a larger structural dimension, thereby effectively improving the cleaning ability of the cleaning device 1.

[0027] Optionally, in some embodiments, the weight of the cleaning mechanism 10 is between 1600 g and 2000 g. For example, any value between 1600 g and 2000 g such as 1600 g, 1650 g, 1750 g, or 2000 g, etc. In this way, while effectively ensuring that the cleaning belt 13 has a sufficiently large first dynamic pressure on the ground 2 to be cleaned, it also ensures that the ground to be cleaned has a sufficiently large dynamic pressure on the transmission inclined plane 23, thereby effectively ensuring the cleaning efficiency and cleaning ability of the cleaning device 1.

[0028] Optionally, in some embodiments, when the ground 2 to be cleaned is horizontally arranged, the ratio of the first dynamic pressure generated by the cleaning belt 13 on the ground 2 to be cleaned under the support of the transmission inclined plane 23 to the second dynamic pressure generated after the transmission inclined plane 23 is removed is between 0.3 and 0.8.

[0029] Specifically, the dynamic pressure is the pressure exerted by the cleaning device 1 on the ground 2 to be cleaned in the working state. During the working process, a larger dynamic pressure is beneficial to improving the cleaning efficiency and cleaning ability of the cleaning belt 13 on the ground 2 to be cleaned. The second dynamic pressure is the dynamic pressure when the cleaning belt 13 directly acts on the ground 2 to be cleaned without the support of the transmission inclined plane 23. Since the gravity of the cleaning mechanism 10 is constant, under the same other conditions, if the supporting effect of the transmission inclined plane 23 on the cleaning mechanism 10 is greater (that is, the dynamic pressure of the cleaning mechanism 10 on the transmission inclined plane 23 is greater), then the corresponding acting force of the cleaning mechanism 10 on the ground 2 to be cleaned, that is, the first dynamic pressure, is smaller. On the contrary, if the supporting effect of the ground 2 to be cleaned on the cleaning mechanism 10 is greater (that is, the first dynamic pressure of the cleaning mechanism 10 on the ground 2 to be cleaned is greater), then the dynamic pressure of the cleaning mechanism on the transmission inclined plane 23 is smaller. Therefore, the first dynamic pressure of the cleaning belt 13 on the ground 2 to be cleaned and the dynamic pressure of the cleaning belt 13 on the transmission inclined plane 23 are negatively correlated. Among them, under the same other conditions, the first dynamic pressure is less than the second dynamic pressure, and the difference between the second dynamic pressure and the first dynamic pressure is affected by the dynamic pressure of the cleaning belt 13 on the transmission inclined plane 23.

[0030] If the ratio of the first dynamic pressure to the second dynamic pressure is too small, it indicates that the first dynamic pressure is small, which affects the cleaning ability and efficiency of the cleaning belt 13 for the ground 2 to be cleaned. If the ratio of the first dynamic pressure to the second dynamic pressure is too large, it indicates that the first dynamic pressure is large while the dynamic pressure of the cleaning belt 13 on the transmission inclined plane 23 is small, which will affect the transmission efficiency of the cleaning belt 13 to cooperate with the transmission inclined plane 23 to transmit the object to be cleaned. Therefore, the ratio of the first dynamic pressure value to the second dynamic pressure value is set between 0.3 and 0.8. For example, the ratio can be any value between 0.3 and 0.8 such as 0.3, 0.4, 0.5, 0.55, 0.6, 0.7, or 0.8. In this way, the pressure distribution of the cleaning belt 13 on the ground 2 to be cleaned and on the transmission inclined plane 23 can be made more reasonable, thereby effectively improving the cleaning ability of the cleaning device 1.

[0031] Optionally, in some embodiments, the ratio of the first dynamic pressure to the second dynamic pressure is greater than or equal to 0.5. Such a setting can effectively ensure the dynamic pressure (i.e., the first dynamic pressure) of the cleaning belt 13 on the ground 2 to be cleaned, and thus effectively ensure the cleaning ability of the cleaning device 1.

[0032] Optionally, in some embodiments, the first dynamic pressure is between 300 and 700 grams-force, such as actual values between 300 grams-force and 700 grams-force like 300 grams-force, 310 grams-force, 350 grams-force, 400 grams-force, or 700 grams-force. In this way, the cleaning ability of the cleaning belt 13 on the ground 2 to be cleaned can be effectively ensured, and thus the cleaning ability of the cleaning device 1 can be effectively ensured. It should be noted that in some embodiments herein, the common weight unit, namely "grams-force, g", is used to represent the magnitude of the dynamic pressure, and the dynamic pressure can be converted to the Newton force unit through the Newtonian mechanics formula. For example, 300 g = 0.3 kg × 9.8 N / kg = 2.94 N.

[0033] Optionally, in some embodiments, the ratio of the contact surface between the cleaning belt 13 and the ground 2 to be cleaned and the contact surface between the cleaning belt 13 and the transmission inclined plane 23 can be adjusted to adjust the magnitude relationship between the first dynamic pressure and the dynamic pressure of the cleaning belt 13 on the transmission inclined plane 23, so as to ensure that the cleaning belt 13 has a sufficiently large first dynamic pressure on the ground 2 to be cleaned while ensuring that the cleaning ground has a sufficiently large dynamic pressure on the transmission inclined plane 23, thereby effectively ensuring the cleaning ability of the cleaning device 1 while effectively improving the transmission efficiency of the cleaning belt 13 to cooperate with the transmission inclined plane 23 to transmit the object to be cleaned.

[0034] Specifically, as Figure 2As shown, in some embodiments, the device body 20 is provided with a wheel body 30. In some embodiments, the device body 20 includes a main frame 21, and the wheel body 30 is disposed on the main frame 21. The wheel body 30 is used to define a support surface that contacts the ground 2 to be cleaned. The device body 20 is supported on the ground 2 to be cleaned through the wheel body 30 so as to travel along the traveling direction X1 through the wheel body 30. It should be noted that the support surface is a virtual surface defined by the wheel body 30. For example, in this embodiment, the device body 20 includes four wheel bodies 30, and the support surface is the common tangent plane at the bottoms of the four wheel bodies 30. After the cleaning device 1 is placed on the ground 2 to be cleaned, the support surface will contact or overlap with the ground 2 to be cleaned. Among them, if the ground 2 to be cleaned is a flat surface, then after the cleaning device 1 is placed on the ground 2 to be cleaned, the support surface overlaps with the ground 2 to be cleaned.

[0035] See Figures 4 to 5, in a reference cross-section a-a perpendicular to the support surface and parallel to the traveling direction X1, the larger the width K1 of the contact surface formed by the cleaning belt 13 and the ground 2 to be cleaned, the larger the area of the contact surface formed by the cleaning belt 13 and the ground 2 to be cleaned. And the larger the width K2 of the transmission inclined surface 23, in order to ensure that the cleaning belt 13 can smoothly cooperate with the transmission inclined surface 23 to transmit the object to be cleaned, the larger the area where the cleaning belt 13 needs to contact the transmission inclined surface 23. If the ratio between the width K1 of the contact surface formed by the cleaning belt 13 pressing against the ground 2 to be cleaned and the width K2 of the transmission inclined surface in the reference cross-section a-a perpendicular to the support surface is too small, it will result in the area of the contact surface formed by the cleaning belt 13 and the ground 2 to be cleaned being relatively small compared to the contact surface area between the cleaning belt 13 and the transmission inclined surface 23, thereby causing the first dynamic pressure to be too small, which is not conducive to the cleaning of the ground 2 to be cleaned by the cleaning belt 13. If the ratio between the width K1 of the contact surface formed by the cleaning belt 13 pressing against the ground 2 to be cleaned and the width K2 of the transmission inclined surface in the reference cross-section a-a perpendicular to the support surface is too large, it will result in the area of the contact surface formed by the cleaning belt 13 and the ground 2 to be cleaned being relatively large compared to the contact surface area between the cleaning belt 13 and the transmission inclined surface 23, thereby causing the dynamic pressure exerted by the cleaning belt 13 on the ground 2 to be cleaned per unit area to be too small, and further not conducive to the cleaning of the ground 2 to be cleaned by the cleaning belt 13. Moreover, this will also cause the fourth dynamic pressure of the cleaning belt 13 on the transmission inclined surface 23 to be too small, which is not conducive to the cleaning belt 13 cooperating with the transmission inclined surface 23 to transmit the object to be cleaned. Therefore, in the reference cross-section a-a perpendicular to the support surface, the ratio between the width K1 of the contact surface formed by the cleaning belt 13 pressing against the ground 2 to be cleaned and the width K2 of the transmission inclined surface is between 0.25 and 0.30. For example, the actual values between 0.25 and 0.30 such as 0.25, 0.26, 0.27, or 0.30, etc. In this way, the distribution ratio of the first dynamic pressure and the fourth dynamic pressure can be made more reasonable, and it can also effectively ensure the dynamic pressure exerted by the cleaning belt 13 on the ground 2 to be cleaned per unit area, thereby effectively improving the cleaning ability of the cleaning device 1.

[0036] In an alternative embodiment, due to the different materials of the ground 2 to be cleaned, it will also directly affect the friction between the cleaning belt 13 and the ground to be cleaned. Since the cleaning mechanism 10 is a cantilever structure, it will further affect the dynamic pressure on the ground to be cleaned, that is, the first dynamic pressure. Among them, in this article, the first dynamic pressure generally refers to the dynamic pressure when working on the ground to be cleaned such as wooden floors and ceramic tiles.

[0037] Optionally, as Figure 6As shown, in some embodiments, on the side of the first roller 11 and / or the second roller 12 facing the transfer inclined plane 23, there is a common tangent DE between the first roller 11 and the second roller 12. Specifically, the first roller 11 has a reference point D, and the second roller 12 has a reference point E. Among them, the line connecting the reference point D and the reference point E is the common tangent DE of the first roller 11 and the second roller 12.

[0038] Among them, the positional relationship between the common tangent DE and the transfer inclined plane 23 directly affects whether the cleaning mechanism 10 can better distribute the dynamic pressure of the cleaning belt 13 on the ground 2 to be cleaned and the transfer inclined plane 23. Among them, since the cleaning mechanism 10 is integrally connected to the equipment main body 20 in a swing rod manner, the positional relationship between the cleaning mechanism 10 and the transfer inclined plane 23 will change with the change of the spatial state of the cleaning device 1, resulting in a change in the positional relationship between the common tangent DE and the transfer inclined plane 23, and further causing the angle J1 between the common tangent DE and the connecting line of the upper and lower ends of the transfer inclined plane 23 to change accordingly. For example, when the cleaning device 1 is in a suspended state, at this time the cleaning mechanism 10 is not supported by the ground 2 to be cleaned, and the cleaning mechanism 10 is arranged closer to the transfer inclined plane 23 under the action of gravity. At this time, the angle J1 between the common tangent DE and the connecting line of the upper and lower ends of the transfer inclined plane 23 is the largest. Another example is that compared with the cleaning device 1 being in a suspended state, when the cleaning device 1 is placed on the ground, the ground 2 to be cleaned supports the cleaning mechanism 10, causing the entire cleaning mechanism 10 to swing a certain angle in the direction away from the transfer inclined plane 23, and further reducing the angle J1 between the common tangent DE and the connecting line of the upper and lower ends of the transfer inclined plane 23.

[0039] And, the cleaning belt 13 described in this application may be in three states: one, the factory state. At this time, the cleaning belt 13 is in the factory state and the cleaning belt 13 is not wetted by liquid. At this time, the fluff layer 132 (as Figure 8 shown) is relatively fluffy, and when it is pressed against the ground 2 to be cleaned, there will be a large deformation; two, the running state. The running state is when the cleaning belt 13 runs in a fixed direction for at least 5 hours and the cleaning belt 13 is in a state of not being wetted by liquid. At this time, the fluff layer 132 will be relatively compacted. When the fluff layer 132 is pressed against the ground 2 to be cleaned, the degree of deformation is relatively reduced; three, the wetting state. The wetting state means that the cleaning belt 13 moves in a fixed direction for at least 5 hours and the cleaning belt 13 is in a state of being wetted by liquid. At this time, when the fluff layer 132 is pressed against the ground 2 to be cleaned, the degree of deformation will be further reduced.

[0040] Therefore, the angle J1 between the common tangent DE and the connecting line of the upper and lower ends of the transfer inclined plane 23 will also change with the different wear states of the cleaning device 1.

[0041] Optionally, as Figure 6As shown, in some embodiments, compared with the cleaning mechanism 10 being in a suspended state, when the cleaning belt 13 presses against the ground 2 to be cleaned, the angle change amount of the angle J1 between the common tangent DE and the connecting line of the upper and lower ends of the transmission inclined plane 23 is between 0.8° and 4.0°.

[0042] Specifically, when the cleaning mechanism 10 is in a suspended state, for example, the cleaning device 1 is entirely suspended or the cleaning device 1 is placed on the ground 2 to be cleaned, but there are low-lying areas on the ground 2 to be cleaned, resulting in a state where the cleaning mechanism 10 cannot be in contact with the ground 2 to be cleaned. Among them, in this state, the cleaning belt 13 presses against the transmission inclined plane 23 but does not press against the ground 2 to be cleaned. The positional relationship between the cleaning mechanism 10 and the transmission inclined plane 23 is also called the second positional relationship. When the cleaning mechanism 10 is in contact with the ground 2 to be cleaned, the cleaning belt 13 presses against the ground 2 to be cleaned, and the positional relationship between the cleaning mechanism 10 and the transmission inclined plane 23 is also called the third positional relationship.

[0043] As Figure 6 shown, the upper end of the transmission inclined plane 23 has a reference point F intersecting with the reference section a-a, and the lower end of the transmission inclined plane 23 has a reference point H intersecting with the reference section a-a. Among them, the connecting line of the upper and lower ends of the transmission inclined plane 23 described in the content of this article is the connecting line FH.

[0044] When the cleaning mechanism 10 is in a suspended state, the bottom of the cleaning belt 13 is located below the support surface. When the cleaning mechanism 10 is in contact with the ground 2 to be cleaned, the support surface contacts the ground 2 to be cleaned, and the ground 2 to be cleaned supports the bottom of the cleaning belt 13, causing the cleaning mechanism 10 to swing a certain distance away from the transmission inclined plane 23 around the first axis z1 (that is, causing the second roller 12 to lift a certain distance relative to the ground 2 to be cleaned), thereby causing the angle of the angle J1 to change. For example, in this embodiment, compared with the cleaning mechanism 10 being in a suspended state, when the cleaning belt 13 presses against the ground 2 to be cleaned, the angle J1 decreases. Of course, when the cleaning device 1 is in a working state and the cleaning mechanism 10 is cleaning the object to be cleaned, it is pushed by the object to be cleaned, causing the cleaning mechanism 10 to swing a certain distance away from the transmission inclined plane 23 around the first axis z1, and further causing the angle J1 to change. During this process, the angle J1 also shows a decreasing trend.

[0045] Among them, when the cleaning belt 13 presses against the ground 2 to be cleaned, if the angle change amount of the included angle J1 is too large, the cleaning belt 13 and the transmission inclined plane 23 cannot contact the transmission inclined plane 23 well, which will affect the transmission efficiency of the cleaning belt 13 cooperating with the transmission inclined plane 23 to transmit the object to be cleaned. If the angle change amount of the included angle J1 is too small, the contact surface between the cleaning belt 13 and the transmission inclined plane 23 will be too large, thus weakening the first dynamic pressure. Therefore, the angle change amount of the included angle J1 is set to be between 0.8° and 4.0°, such as actual values between 0.8° and 4.0° like 0.8°, 1.5°, 1.6°, 2°, 3° or 4°, etc. This can effectively ensure that the first dynamic pressure is large enough, and at the same time, can effectively ensure that the cleaning belt 13 is in full contact with the transmission inclined plane 23, thereby effectively improving the cleaning ability and cleaning efficiency of the cleaning device 1. It should be noted that in the solution of this embodiment, regardless of the state of the cleaning belt 13, compared with the cleaning mechanism 10 being in a suspended state, when the cleaning belt 13 presses against the ground 2 to be cleaned, the angle change amount of the included angle J1 between the common tangent DE and the connection line of the upper and lower ends of the transmission inclined plane 23 is between 0.8° and 4.0°.

[0046] Optionally, as Figure 2 and Figure 6 shown, in some implementations, the device main body 20 includes a main frame 21 and a guiding member 22 disposed on the main frame 21. The main frame 21 forms a first transmission inclined plane 211, and the guiding member 22 forms a second transmission inclined plane 221. The first transmission inclined plane 211 and the second transmission inclined plane 221 are connected to form the transmission inclined plane 23. Among them, the guiding member 22 is disposed at the lower end of the first transmission inclined plane 211 to cooperate with the cleaning belt 13 to guide the object to be cleaned on the ground 2 to be cleaned to the first transmission inclined plane 211, thereby effectively ensuring that the cleaning belt 13 can efficiently introduce the object to be cleaned into the first transmission inclined plane 211. One end of the first roller 11 and the link assembly 14 is rotatably supported on the main frame 21, so that the cleaning mechanism 10 is integrally connected to the device main body 20 in a swing rod manner. In the working state, the cleaning belt 13 is pressed against the ground 2 to be cleaned, the first transmission inclined plane 211 and the second transmission inclined plane 221 by the gravity of the roller mechanism 15 through the second roller 12.

[0047] It should be noted that the dynamic pressure (the fourth dynamic pressure) of the cleaning belt 13 (or the cleaning mechanism 10) on the transmission inclined plane 23 described in the content of this article includes the dynamic pressure of the cleaning belt 13 (or the cleaning mechanism 10) on the first transmission inclined plane 211 and the dynamic pressure on the second transmission inclined plane 221.

[0048] Optionally, as Figure 6As shown, in some embodiments, within a reference cross-section a-a perpendicular to the support surface, there is a first connection line FG between the lower end and the upper end of the first transmission inclined surface 211. The common tangent line DE is also referred to as the common tangent line DE between the first roller 11 and the second roller 12 on the side of the first roller 11 and / or the second roller 12 facing the first transmission inclined surface 211. Specifically, the upper end of the first transmission inclined surface 211, which is also the upper end of the transmission inclined surface 23, has a reference point F intersecting with the reference cross-section a-a, and the lower end of the first transmission inclined surface 211 has a reference point G intersecting with the reference cross-section a-a. Among them, the connection line between the reference point F and the reference point G is the first connection line FG.

[0049] Optionally, as Figure 6 shown, in some embodiments, when the cleaning belt 13 contacts the first transmission inclined surface 211, along the extension direction X2 of the second roller 12 towards the first roller 11, the common tangent line DE is gradually arranged away from the first connection line FG.

[0050] Specifically, since the gravity of the cleaning mechanism 10 is constant, under the same other conditions, if the supporting effect of the first transmission inclined plane 211 on the cleaning mechanism 10 is greater (that is, the dynamic pressure of the cleaning mechanism 10 on the first transmission inclined plane 211 is greater), then the acting force of the corresponding cleaning mechanism 10 on the ground 2 to be cleaned, that is, the first dynamic pressure, will be smaller. On the contrary, if the supporting effect of the ground 2 to be cleaned on the cleaning mechanism 10 is greater (that is, the first dynamic pressure of the cleaning mechanism 10 on the ground 2 to be cleaned is greater), then the dynamic pressure of the cleaning mechanism on the first transmission inclined plane 211 will be smaller. Therefore, when the cleaning mechanism 10 is in the working state, it not only needs to keep in contact with the first transmission inclined plane 211, but also needs to keep in contact with the ground 2 to be cleaned, so as to ensure the transmission efficiency of the cleaning belt 12 cooperating with the first transmission inclined plane 211 to transmit the object to be cleaned, and at the same time, it can efficiently clean the ground 2 to be cleaned. Among them, when the cleaning belt 13 contacts the first transmission inclined plane 211, along the extension direction X2, setting the common tangent DE to gradually move away from the first connection line FG can make the common tangent DE gradually move away from the first connection line FG along the extension direction X2 in the working state. Furthermore, at least three contact relationships between the first transmission inclined plane 211 and the cleaning belt 13 are respectively as follows: "The first transmission inclined plane 211 contacts the cleaning belt 13, interferes with the cleaning belt 13, and supports the cleaning belt 13 to support the cleaning mechanism 10", "The first transmission inclined plane 211 contacts the cleaning belt 13, and there is no interference or the interference amount is small with the cleaning belt 13, and the first transmission inclined plane 211 does not support the cleaning belt 13 or the supporting effect is small", and "The first transmission inclined plane 211 is spaced from the cleaning belt 13 and is indirectly contacted through the vibration of the cleaning belt 13 during operation". In this way, the contact area between the first transmission inclined plane 211 and the cleaning mechanism 10 in the working state can be effectively reduced, thereby reducing its supporting effect, and on the premise of ensuring the dynamic pressure of the cleaning belt 13 on the first transmission inclined plane 211, the first dynamic pressure of the cleaning belt 13 on the ground 2 to be cleaned can be effectively increased.

[0051] And, referring to Figure 2As shown, in some embodiments, the cleaning device 1 further includes a storage box 40. The storage box 40 is provided with a storage space 41 for storing objects to be cleaned. The storage box 40 is detachably arranged on the main frame, and the storage box 40 is arranged at the rear side of the first transfer slope 211 (for the definitions of the front side and the rear side of the first transfer slope 211, reference can be made to the definitions of the front side and the rear side of the transfer slope 23 above, which will not be elaborated here in detail). An outflow port 231 is formed between the upper end of the first transfer slope 211 and the cleaning belt. The outflow port 231 is communicated with the storage space 41. The objects to be cleaned flowing from the ground 2 to be cleaned to the first transfer slope 211 can flow into the storage space 41 along the outflow port 231. Among them, when the distance between the first roller 11 and the second roller 12 is fixed, the relative positional relationship between the common tangent line DE and the first connection line FG, that is, along the extension direction X2, the common tangent line DE is gradually arranged farther away from the first connection line FG, which can make the distance between the upper end of the first transfer slope 211, the first roller 11 and the cleaning belt 13 farther, so as to effectively increase the size of the outflow port 231, so that the objects to be cleaned can smoothly flow into the storage box 40 from the outflow port 231. It should be noted that in the solution of this embodiment, no matter what state the cleaning belt 13 is in, when the cleaning belt 13 contacts the first transfer slope 211, along the extension direction X2 from the second roller 12 towards the first roller 11, the common tangent line DE is always arranged to gradually move away from the first connection line FG.

[0052] When the cleaning belt 13 contacts the first transfer slope 211, there is not necessarily pressure between the cleaning belt 13 and the first transfer slope 211, that is, there is not necessarily an interaction force between the cleaning belt 13 and the first transfer slope 211. In other words, when the cleaning mechanism 10 contacts the first transfer slope 211 (that is, when the cleaning belt 13 contacts the first transfer slope 211), the relative positional relationship between the cleaning mechanism 10 and the first transfer slope 211 includes at least three special positional relationships.

[0053] The first positional relationship is that the cleaning mechanism 10 contacts the first transfer slope 211, and the interaction force between the cleaning mechanism 10 and the first transfer slope 211 is not enough to cause the cleaning belt 13 to deform again (it should be noted that before the cleaning belt 13 contacts the first transfer slope 211, the cleaning belt 13 may also be deformed, but this deformation is not formed by the interaction force between the cleaning mechanism 10 and the first transfer slope 211, but is formed under the action of gravity). At this time, the cleaning belt 13 contacts the first transfer slope 211 in a non-deformed manner, and external force may be required to achieve this relationship.

[0054] The second positional relationship is that the cleaning belt 13 presses against the first transmission inclined surface 211, and the cleaning belt 13 does not press against the ground 2 to be cleaned. In this positional relationship, the cleaning mechanism 10 contacts the first transmission inclined surface 211, and the mutual force between the cleaning mechanism 10 and the first transmission inclined surface 211 causes the cleaning belt 13 to deform again. Among them, the second characteristic positional relationship can be understood as the state when the cleaning mechanism 10 is not supported by the ground 2 to be cleaned. For example Figure 7 As shown, when the cleaning device 1 is placed on the ground to be cleaned, the cleaning mechanism 10 is in a suspended state, which is the state when the ground 2 to be cleaned does not support the cleaning mechanism 10. Of course, in some embodiments, this state can also be the state when the entire cleaning device 1 is suspended and the bottom of the cleaning device 1 faces the ground 2 to be cleaned.

[0055] The third positional relationship is as Figure 2 shown. When the cleaning mechanism 10 abuts against the ground to be cleaned, the cleaning mechanism 10 presses against the first transmission inclined surface 211, and the cleaning mechanism 10 presses against the surface 2 to be cleaned (or in some embodiments, it is also called that the cleaning belt 13 presses against the ground 2 to be cleaned). At this time, the cleaning belt 13 contacts the ground 2 to be cleaned and the second transmission inclined surface 211 respectively, and there is a mutual force. The ground 2 to be cleaned and the second transmission inclined surface 211 jointly support the cleaning mechanism 10.

[0056] Among them, when the cleaning device 1 is in a working state, the relative positional relationship between the cleaning mechanism 10 and the first transmission inclined surface 211 is in the third positional relationship. Of course, in the face of extreme working conditions, it changes from the third positional relationship to the second positional relationship. For example Figure 7 as shown, when the cleaning device 1 moves to a pothole, the cleaning mechanism 10 cannot contact the ground 2 to be cleaned. At this time, under the action of gravity, the cleaning mechanism 10 swings around the first axis z1 in the direction towards the first transmission inclined surface 211, so that the relative positional relationship between the cleaning mechanism 10 and the first transmission inclined surface 211 changes from the third positional relationship to the second positional relationship.

[0057] Therefore, when the cleaning belt 13 contacts the first transmission inclined surface 211, along the extension direction X2, the common tangent DE gradually moves away from the first connection line FG. It should be understood that at least when the relative positional relationship between the cleaning mechanism 10 and the first transmission inclined surface 211 is in the third positional relationship, along the extension direction X2, the common tangent DE gradually moves away from the first connection line FG. Optionally, in the embodiments of the present application, when the relative positional relationship between the cleaning mechanism 10 and the first transmission inclined surface 211 is in any one of the first positional relationship, the second positional relationship, and the third positional relationship, along the extension direction X2, the common tangent DE gradually moves away from the first connection line FG.

[0058] Optionally, as Figure 6As shown, in some embodiments, when the cleaning belt 13 contacts the first transmission inclined plane 211 in a non-deformed manner (i.e., when the relative positional relationship between the cleaning mechanism 10 and the first transmission inclined plane 211 is in the first positional relationship), along the extension direction X2, the common tangent DE gradually moves away from the first connection line FG.

[0059] Specifically, when the relative positional relationship between the cleaning mechanism 10 and the first transmission inclined plane 211 is in the third positional relationship, when the relative positional relationship between the cleaning mechanism 10 and the first transmission inclined plane 211 is in the first positional relationship, the cleaning mechanism 10 is closer to the first transmission inclined plane 211. Therefore, when the cleaning belt 13 contacts the first transmission inclined plane 211 in a non-deformed manner, along the extension direction X2 of the second roller 12 towards the first roller 11, setting the common tangent DE to gradually move away from the first connection line FG can ensure that in the working state, along the extension direction X2, the common tangent DE gradually moves away from the first connection line FG, thereby enabling the first transmission inclined plane 211 to have at least three contact relationships with the cleaning belt 13 in sequence, which are respectively "the first transmission inclined plane 211 contacts the cleaning belt 13, interferes with the cleaning belt 13, and supports the cleaning belt 13 to support the cleaning mechanism 10", "the first transmission inclined plane 211 contacts the cleaning belt 13, and there is no interference or less interference with the cleaning belt 13, and the first transmission inclined plane 211 does not play a supporting role or has a small supporting role on the cleaning belt 13", and "the first transmission inclined plane 211 and the cleaning belt 13 are indirectly in contact through the vibration of the cleaning belt 13". In this way, the supporting effect of the first transmission inclined plane 211 on the cleaning mechanism 10 in the working state can be effectively reduced, so as to effectively increase the first dynamic pressure of the cleaning belt 13 on the ground 2 to be cleaned on the premise of ensuring the dynamic pressure of the cleaning belt 13 on the first transmission inclined plane 211 and effectively realizing the contact.

[0060] Optionally, as Figure 6 As shown, in some embodiments, when the cleaning belt 13 contacts the first transmission inclined plane 211 in a non-deformed manner, the first included angle J2 between the first connection line FG and the common tangent DE is between 2° and 13°. For example, actual values between 2° and 13° such as 2°, 3°, 4°, 7°, 10°, or 13°. Such a setting can make the first included angle J2 between the first connection line FG and the common tangent DE within a reasonable range in the working state, so as to effectively reduce the supporting effect of the first transmission inclined plane 211 on the cleaning mechanism 10 in the working state, and thus effectively increase the first dynamic pressure of the cleaning belt 13 on the ground 2 to be cleaned on the premise of ensuring the dynamic pressure of the cleaning belt 13 on the first transmission inclined plane 211.

[0061] Optionally, in some embodiments, compared with the cleaning mechanism 10 in a suspended state (second positional relationship), when the cleaning belt 13 presses against the ground 2 to be cleaned, the angular change amount of the first included angle J2 is between 0.5° and 3°. Specifically, the angular change amount of the first included angle J2 when changing from the second positional relationship to the third positional relationship can indirectly affect the interference amount between the cleaning belt 13 and the first transmission inclined plane 211 when the cleaning belt 13 presses against the first transmission inclined plane 211 and the ground 2 to be cleaned. Among them, the angular change amount is positively correlated with the interference amount between the cleaning belt 13 and the first transmission inclined plane 211. If the interference amount between the cleaning belt 13 and the first transmission inclined plane 211 is too large, the supporting effect of the first transmission inclined plane 211 on the cleaning mechanism 10 will be too large, thereby weakening the first dynamic pressure of the cleaning belt 13 on the ground 2 to be cleaned and affecting the cleaning ability of the cleaning belt 13 on the ground 2 to be cleaned. If the interference amount between the cleaning belt 13 and the first transmission inclined plane 211 is too small, the dynamic pressure of the cleaning belt 13 on the first transmission inclined plane 211 will be too small, which is not conducive to the cleaning belt 13 cooperating with the first transmission inclined plane 211 to transport the object to be cleaned. Therefore, in some embodiments, the angular change amount of the first included angle J2 when changing from the second positional relationship to the third positional relationship is between 0.5° and 3°. For example, the actual values between 0.5° and 3° such as 0.5°, 0.6°, 1° or 3°. In this way, it can effectively ensure that the dynamic pressure of the cleaning belt 13 on the first transmission inclined plane 211 is large enough to effectively ensure the transmission efficiency of the cleaning belt 13 cooperating with the first transmission inclined plane 211 to transport the object to be cleaned, and at the same time, it can effectively increase the first dynamic pressure of the cleaning belt 13 on the ground 2 to be cleaned, thereby effectively improving the cleaning ability of the cleaning device 1. It should be noted that in the solution of this embodiment, regardless of the state of the cleaning belt 13, compared with the cleaning mechanism 10 in a suspended state, when the cleaning belt 13 presses against the ground 2 to be cleaned, the angular change amount of the first included angle J2 is always between 0.5° and 3°.

[0062] Optionally, as Figure 6 shown, in some embodiments, there is a second connection line GH between the lower end and the upper end of the second transmission inclined plane 221. The second included angle J5 between the second connection line GH and the first connection line FG is between 3° and 11°. Specifically, the upper end of the second transmission inclined plane 221 is connected to the lower end of the first transmission inclined plane 211. The reference point F is the common reference point of the lower end of the first transmission inclined plane 211 and the upper end of the second transmission inclined plane 221. The lower end of the second transmission inclined plane 221 is the lower end of the transmission inclined plane 23, which has a reference point H intersecting with the reference section a-a. Among them, the connection line between the reference point G and the reference point H is the second connection line GH.

[0063] Furthermore, as Figure 4 and Figure 6As shown, the second transfer slope 221 is closer to the second roller 12 than the first transfer slope 211. The cleaning belt 13 wound around the outer circumference of the second roller 12 is arc-shaped. Therefore, the second included angle J5 is set to be between 3° and 11°. For example, the actual values between 3° and 11° such as 3°, 4°, 4.5°, 6°, or 11° can make the second transfer slope 221 "bend" towards the cleaning belt 13 relative to the first transfer slope 211, so that the transfer slope 23 can better match the outer contour of the cleaning belt 13, thereby enabling the cleaning belt 13 to more efficiently cooperate with the guide member 22 to guide the object to be cleaned on the ground 2 to the transfer slope 23, and then effectively improving the transfer efficiency of the cleaning belt 13 in cooperating with the transfer slope 23 to transfer the object to be cleaned. Moreover, setting the second included angle J5 to be between 3° and 11° can also effectively ensure that there is a sufficiently large object inlet gap 3 between the lower end of the second transfer slope 221 and the cleaning belt 13, so as to ensure that the cleaning belt 13 can efficiently transfer the object to be cleaned to the transfer slope 23 along the object inlet gap 3, and then effectively improve the cleaning ability of the cleaning device 1.

[0064] Optionally, as Figure 4 and Figure 6As shown, in some embodiments, the cleaning device 1 has a first reference line Iz2, a second reference line Gz2, and a third reference line Hz2. On the reference cross-section a-a, the first reference line Iz2 passes through the second axis z2 and is perpendicular to the support surface. The second reference line Gz2 passes through the second axis z2 and the upper end of the second transfer slope 221. The third reference line Hz2 passes through the second axis z2 and the lower end of the second transfer slope 221. When the cleaning belt 13 contacts the first transfer slope 211 in a non-deformed manner, the angle J3 between the first reference line Iz2 and the second reference line Gz2 is between 43° and 51°. The angle J4 between the first reference line Iz2 and the third reference line Hz2 is between 22° and 27°. Specifically, the value of the angle J4 directly affects the size of the material inlet gap 3 in the working state. Among them, the smaller the angle J4, the smaller the material inlet gap 3, and the larger the angle J4, the larger the material inlet gap 3. Relative to when the cleaning belt 13 contacts the first transfer slope 211 in a non-deformed manner, when the cleaning device 1 is placed on the ground, the angle J4 will be reduced to a certain extent. Therefore, when the cleaning belt 13 contacts the first transfer slope 211 in a non-deformed manner, the angle J4 between the first reference line Iz2 and the third reference line Hz2 is set between 22° and 27°. For example, the actual values between 22° and 27° such as 22°, 23°, 24.5°, or 27°. In this way, it can effectively ensure that when the cleaning device 1 is placed on the ground to be cleaned 2, the angle J4 can be within a relatively reasonable angle range, so as to effectively ensure that the size of the material inlet gap 3 between the lower end of the second transfer slope 221 and the cleaning belt 13 in the working state is more reasonable, so as to ensure that the cleaning belt 13 can efficiently transfer the object to be cleaned to the transfer slope 23 along the material inlet gap 3, and then effectively improve the cleaning ability of the cleaning device 1. Further, the upper end of the second transfer slope 221 is the connection end with the first transfer slope 211. Therefore, the upper end of the second transfer slope 221 is one of the turning points of the transfer slope 23. When the second angle J5 is certain, the angle J3 directly affects the matching degree between the transfer slope 23 and the outer peripheral contour of the cleaning belt 13 and the size of the material inlet gap 3, thereby directly affecting the transfer efficiency of the cleaning belt 13 in cooperating with the transfer slope 23 to transfer the object to be cleaned and the guiding efficiency of the cleaning belt to guide the object to be cleaned to the transfer slope 23.

[0065] Moreover, when the cleaning mechanism 10 abuts against the ground 2 to be cleaned while contacting the first transmission inclined plane 211 in a non-deformed manner with respect to the cleaning belt 13, the included angle J3 will be reduced to a certain extent. When the cleaning belt 13 contacts the first transmission inclined plane 211 in a non-deformed manner, the included angle J3 is set between 43° and 51°, for example, the actual values between 43° and 51° such as 43°, 43.5°, 45°, 48°, or 51°. In this way, it can effectively ensure that when the cleaning device 1 is placed on the ground 2 to be cleaned, the included angle J3 can be within a relatively reasonable angle range, thereby effectively ensuring a high degree of matching between the transmission inclined plane 23 and the outer peripheral contour of the cleaning belt 13 and ensuring that the size of the object inlet gap 3 is more reasonable. Thus, while effectively improving the transmission efficiency of the cleaning belt 13 in cooperating with the transmission inclined plane 23 to transmit the object to be cleaned, it can also enable the cleaning belt 13 to more efficiently guide the object to be cleaned to the transmission inclined plane 23, and further effectively improve the cleaning ability of the cleaning device 1.

[0066] Optionally, as Figure 2 and Figure 6 shown, in some embodiments, when the cleaning belt 13 presses against the ground 2 to be cleaned, the vertical distance L1 between the upper end of the first transmission inclined plane 211 and the common tangent line DE is between 6.5 mm and 8.0 mm, for example, the actual values between 6.5 mm and 8.0 mm such as 6.5 mm, 7 mm, or 8.0 mm. Specifically, if the vertical distance L1 between the upper end of the first transmission inclined plane 211 and the common tangent line DE is too small, it will easily cause the object to be cleaned to be stuck between the upper end of the first transmission inclined plane 211 and the cleaning belt 13, resulting in the cleaning device 1 being unable to work properly. If the vertical distance L1 is too large, it will easily cause the cleaning belt 13 to be unable to contact the area near the upper end of the first transmission inclined plane 211 during the working state, so that the cleaning belt 13 cannot cooperate with the first transmission inclined plane 211 to efficiently guide the object to be cleaned into the storage box 40. Therefore, such a setting makes the structural size of the outflow port 231 between the upper end of the first transmission inclined plane 211 and the cleaning belt 13 more reasonable, enabling the cleaning device 1 to clean objects to be cleaned with larger structural sizes, thereby effectively improving the cleaning ability of the cleaning device 1. Moreover, such a setting can also ensure that the cleaning belt 13 can maintain contact with the area near the upper end of the first transmission inclined plane 211 during the working state, thereby effectively improving the transmission efficiency of the cleaning belt 13 in cooperating with the transmission inclined plane 23 to transmit the object to be cleaned. It should be noted that when the cleaning belt 13 presses against the ground 2 to be cleaned, the cleaning device 1 is in the state of being placed on the ground 2 to be cleaned.

[0067] Optionally, as Figure 2 and Figure 6As shown, in some embodiments, the vertical projection of the upper end of the first transmission inclined surface 211 onto the common tangent line DE is located between the upper end and the lower end of the common tangent line DE. Such a setting enables the first transmission inclined surface 211 to overlap as much as possible with the area between the upper end and the lower end of the common tangent line DE, thereby ensuring that the cleaning belt 13 can contact the first transmission inclined surface 211 as much as possible (it should be noted that this contact does not necessarily involve force, and for the specific contact relationship between the first transmission inclined surface 211 and the cleaning belt 13, reference can be made to the description in the above embodiments). As a result, the efficiency of the cleaning belt 13 in cooperating with the first transmission inclined surface 211 to transport the object to be cleaned is effectively improved.

[0068] Optionally, in some embodiments, the ratio of the distance from the projection point T formed by the vertical projection of the upper end of the first transmission inclined surface 211 onto the common tangent line DE to the upper end of the common tangent line DE to the length of the common tangent line DE is between 0.40 and 0.49. For example, actual values between 0.40 and 0.49 such as 0.40, 0.41, 0.42, or 0.49, etc. Such a setting makes the distance between the upper end of the first transmission inclined surface 211, the first roller 11, and the cleaning belt 13 more reasonable. While enabling the first transmission inclined surface 211 to contact the cleaning belt 13 as much as possible, it can effectively reduce the interference of the first roller 11 on the flow outlet 231. Furthermore, while effectively improving the transmission efficiency of the cleaning belt 13 in cooperating with the first transmission inclined surface 211 to transport the object to be cleaned, the cleaning ability of the cleaning device 1 is effectively improved.

[0069] Optionally, as Figure 8 shown, in some embodiments, the cleaning belt 13 includes a base layer 131 and a fluff layer 132 provided on the outer peripheral surface of the base layer 131. When the cleaning belt 13 is pressed against the ground 2 to be cleaned, the ratio of the maximum interference amount of the transmission inclined surface 23 on the fluff layer 132 to the fluff length L2 is between 0.19 and 0.60.

[0070] Specifically, the "fluff length L2 of the fluff layer 132" described in this application refers to the length of the fluff when it is not worn and in a naturally stretched state. It should be noted that in the description of this application, the interference amount of any component on the fluff layer 132 refers to the difference obtained by subtracting the distance between the component and the base layer 131 from the fluff length L2 of the fluff layer 132. In addition, if the distance between the component and the base layer 131 is variable, the interference amount of the corresponding position of the component on the fluff layer 132 is the fluff length L2 of the fluff layer 132 minus the distance between the corresponding position of the component and the base layer 131. For example, the interference amount of the transmission inclined surface 23 on the fluff layer 132 is the difference obtained by subtracting the distance between each position of the transmission inclined surface 23 and the corresponding position of the base layer 131 from the fluff length L2 of the fluff layer 132.

[0071] For example, the maximum interference amount of the transmission inclined surface 23 on the fluff layer 132 is the difference obtained by subtracting the shortest distance from the fluff length L2 of the fluff layer 132 corresponding to the shortest distance from the base layer 131 on the transmission inclined surface 23.

[0072] Among them, when the cleaning belt 13 is pressed against the ground 2 to be cleaned and the cleaning belt 13 is in a stationary state, there is a shortest vertical distance between the base layer 131 and the transmission inclined surface 23. Correspondingly, the maximum interference amount of the transmission inclined surface 23 on the fluff layer 132 is the fluff length L2 of the fluff layer 132 minus the shortest vertical distance. Among them, the area where the shortest vertical distance exists between the base layer 131 and the transmission inclined surface 23 is located in the area of the transmission inclined surface 23 close to the ground 2 to be cleaned. For example, it is in the vicinity of the connection between the first transmission inclined surface 211 and the second transmission inclined surface 221. And, the ratio of the maximum interference amount of the transmission inclined surface 23 on the fluff layer 132 to the fluff length L2 directly affects the dynamic pressure of the cleaning belt 13 on the transmission inclined surface 23 (that is, the fourth dynamic pressure). If this ratio is too large, it will increase the dynamic pressure of the cleaning belt 13 on the transmission inclined surface 23, thereby weakening the first dynamic pressure. If this ratio is too small, it will affect the dynamic pressure of the cleaning belt 13 on the transmission inclined surface 23, thereby affecting the transmission efficiency of the cleaning belt 13 for transporting the object to be cleaned. Therefore, the ratio of the maximum interference amount of the transmission inclined surface 23 on the fluff layer 132 to the fluff length L2 is set to be between 0.19 and 0.60. For example, the actual values between 0.19 and 0.60 such as 0.19, 0.20, 0.40 or 0.60 can make the pressure distribution of the cleaning belt 13 on the ground 2 to be cleaned and on the transmission inclined surface 23 more reasonable, thereby effectively improving the cleaning efficiency and cleaning ability of the cleaning device 1.

[0073] It should be noted that regardless of the state of the cleaning belt 13, the fluff length L2 remains unchanged. However, in different states, when the cleaning belt 13 is pressed against the ground 2 to be cleaned, the interference amount of the transmission inclined surface 23 on the fluff layer 132 will change to a certain extent. Therefore, when the cleaning belt 13 is pressed against the ground 2 to be cleaned, the ratio of the maximum interference amount of the transmission inclined surface 23 on the fluff layer 132 to the fluff length L2 of the fluff layer 132 will also change to a certain extent. However, in the solution of this embodiment, regardless of the state of the cleaning belt 13, when the cleaning belt 13 is pressed against the ground to be cleaned, this ratio can always be between 0.19 and 0.60.

[0074] Optionally, in some embodiments, the fluff length L2 of the fluff layer 132 is between 6 mm and 8 mm. For example, the actual values between 6 mm and 8 mm such as 6 mm, 6.5 mm, 7 mm or 8 mm can effectively ensure the sweeping area of the cleaning belt 13, and further effectively ensure the transmission efficiency of the cleaning belt 13 for transporting the object to be cleaned in cooperation with the transmission inclined surface 23.

[0075] Optionally, in some embodiments, the weight per unit area of the villus layer 132 is 550-700 g / m². For example, the actual values between 550-700 g / m² such as 550 g / m², 560 g / m², 600 g / m² or 700 g / m², etc. In this way, the kinetic energy of the cleaning belt 13 after rotation can be effectively improved, thereby effectively improving the cleaning ability of the cleaning belt 13 for the ground 2 to be cleaned and the transmission ability of cooperating with the transmission inclined plane 23 to transmit the object to be cleaned.

[0076] It should be noted that the villus length L2 of the villus layer 132 and the weight per unit area of the villus layer 132 should refer to the villus length and the weight per unit area of the villus layer 132 when the cleaning belt 13 leaves the factory.

[0077] Optionally, in some embodiments, when the cleaning belt 13 presses against the ground 2 to be cleaned and is in the process of rotation (i.e., in the working state), the first transmission inclined plane 211 forms an interference with the villus layer 132 between the lower end and the upper end of the first transmission inclined plane 211. In this way, the transmission efficiency of the cleaning belt 13 cooperating with the first transmission inclined plane 211 to transmit the object to be cleaned can be effectively improved.

[0078] Optionally, in some embodiments, when the cleaning belt 13 presses against the ground 2 to be cleaned and is stationary, the upper end of the first transmission inclined plane 211 is spaced from the outer peripheral surface of the villus layer 132, and during the rotation of the cleaning belt 13, an interference is formed with the villus layer 132 through the vibration of the cleaning belt 13. Specifically, when the cleaning belt 13 presses against the ground 2 to be cleaned and is stationary, the upper end of the first transmission inclined plane 211 and the area of the first transmission inclined plane 211 near its upper end may not form an interference or contact with the villus layer 132, that is, the upper end of the first transmission inclined plane 211 is spaced from the outer peripheral surface of the villus layer. When the cleaning belt 13 rotates, the rotation of the cleaning belt 13 causes the villus layer 132 to vibrate or swing, so that an interference is formed between the villus layer 132 and both the upper end and the lower end of the first transmission inclined plane 211. In this way, not only can the transmission efficiency of the cleaning belt 13 cooperating with the first transmission inclined plane 211 to transmit the object to be cleaned be effectively improved, but also the support of the first transmission inclined plane 211 for the cleaning mechanism 10 can be effectively reduced, thereby effectively increasing the first dynamic pressure, and thus effectively improving the cleaning ability of the cleaning belt 13 for the ground 2 to be cleaned.

[0079] Optionally, in some embodiments, the base layer 131 is a flexible base layer, and at least a part of the cleaning belt 13 located between the first transmission inclined plane 211 and the link assembly 14 is spaced from the link assembly 14, so that the cleaning belt 13 can vibrate back and forth in a direction perpendicular to the cleaning belt 13 during the rotation process, thereby realizing the interference between the villus layer 132 and the upper end of the first transmission inclined plane 211.

[0080] In an alternative embodiment, by directly pressing the cleaning belt 13 onto the first transfer inclined surface 211 and through the vibration of the cleaning belt 13, interference can also be achieved between the fluff layer 132 and the lower end and the upper end of the first transfer inclined surface 211, thereby ensuring the contact between the cleaning belt 13 and the first transfer inclined surface 211.

[0081] Optionally, in some embodiments, the ratio of the interference amount of the lower end of the first transfer inclined surface 211 on the fluff layer 132 to the interference amount of the upper end of the first transfer inclined surface 211 on the fluff layer 132 is between 1.5 and 10.0. Specifically, the ratio of the interference amount of the lower end of the first transfer inclined surface 211 on the fluff layer 132 to the interference amount of the upper end of the first transfer inclined surface 211 on the fluff layer 132 can indirectly affect the area of the region where the first transfer inclined surface 211 is in direct contact with the cleaning belt 13, and further affect the first dynamic pressure of the cleaning belt 13 on the ground 2 to be cleaned and the dynamic pressure of the cleaning belt 13 on the first transfer inclined surface 211. Therefore, setting this ratio between 1.5 and 10.0, for example, actual values between 1.5 and 10.0 such as 1.5, 2.0, 8.0, or 10.0, can make the ratio between the first dynamic pressure and the dynamic pressure of the cleaning belt 13 on the first transfer inclined surface 211 more reasonable, thereby effectively improving the cleaning ability of the cleaning belt 13 on the ground 2 to be cleaned. While effectively improving the cleaning ability of the cleaning device 1, it can also effectively improve the transmission efficiency of the cleaning belt 13 in cooperating with the first transfer inclined surface 211 to transmit the object to be cleaned. It should be noted that, as described above, when the cleaning belt 13 is in a stationary state, the interference amount of the upper end of the first transfer inclined surface 211 on the fluff layer 132 can be 0, but when the cleaning belt 13 is in the process of rotation, the rotation of the cleaning belt 13 causes the fluff layer 132 to vibrate or swing, which can make the upper end of the first transfer inclined surface 211 have an interference amount on the fluff layer 132. It should be noted that regardless of the state of the cleaning belt 13, the fluff length L2 remains unchanged, but in different states, when the cleaning belt 13 is pressed against the ground 2 to be cleaned, the interference amount of the transfer inclined surface 23 on the fluff layer 132 will change to a certain extent. Therefore, when the cleaning belt 13 is pressed against the ground 2 to be cleaned, the ratio of the maximum interference amount of the transfer inclined surface 23 on the fluff layer 132 to the fluff length L2 of the fluff layer 132 will also change to a certain extent, but in the solution of this embodiment, the ratio of the interference amount of the lower end of the first transfer inclined surface 211 on the fluff layer 132 to the interference amount of the upper end of the first transfer inclined surface 211 on the fluff layer 132 always remains between 1.5 and 10.0.

[0082] Optionally, as Figure 2As shown, in some embodiments, the cleaning device 1 further includes a wiper member 50 fixedly disposed on the device main body 20. The wiper member 50 abuts against the cleaning belt 13 and is configured to clean the cleaning belt 13 during the movement of the cleaning belt 13. Specifically, during the process that the cleaning belt 13 cleans the ground and cooperates with the transfer inclined plane 23 to transfer the object to be cleaned, the cleaning liquid and the object to be cleaned are adhered to the fluff layer 132 of the cleaning belt 13. Therefore, the wiper member 50 is provided such that the wiper member 50 abuts against the cleaning belt 13, that is, the wiper member 50 extends to the fluff layer 132 of the cleaning belt 13. In this way, the wiper member 50 can scrape off the cleaning liquid and the object to be cleaned adhered to the fluff layer 132 during the rotation of the cleaning belt 13, thereby effectively preventing the cleaning liquid and the object to be cleaned adhered to the fluff layer 132 from falling back onto the ground to be cleaned 2 again or splashing into the interior of the cleaning device 1, and further effectively improving the cleaning efficiency and cleaning ability of the cleaning device 1.

[0083] Optionally, in some embodiments, the first dynamic pressure and the second dynamic pressure are formed when the wiper member 50 and the cleaning belt 13 remain in an abutting state, that is, whether the cleaning mechanism 10 is in a state supported by the transfer inclined plane 23 or in a state without the support of the transfer inclined plane 23, the wiper member 50 abuts against the cleaning belt 13. In this way, it can be effectively ensured that after the cleaning device 1 is placed on the ground to be cleaned, the wiper member 50 can still effectively abut against the cleaning belt 13, thereby effectively ensuring the cleaning function of the wiper member 50 on the cleaning belt 13.

[0084] The wiper member 50 provides a certain support to the cleaning mechanism 10 and affects the dynamic pressure of the cleaning belt 13 on the ground to be cleaned 2 and the transfer inclined plane 23 to a certain extent. Therefore, in some embodiments, the ratio of the third dynamic pressure generated by the cleaning belt 13 on the ground to be cleaned 2 when the transfer inclined plane 23 supports the cleaning belt 13 and the wiper member 50 is removed to the first dynamic pressure is between 1.07 and 1.80. For example, the ratio can be an actual value between 1.07 and 1.80 such as 1.07, 1.50 or 1.80. With such a setting, when the cleaning device 1 is in a working state, on the premise that the cleaning mechanism 10 can ensure sufficient abutting force with the wiper member 50, the acting force can be applied to the ground to be cleaned 2 and the transfer inclined plane 23 as much as possible, thereby effectively improving the cleaning ability and cleaning efficiency of the cleaning mechanism 10.

Any equivalent device or equivalent process transformation made by using the content of the specification and drawings of the present application, or directly or indirectly applied to other related technical fields, shall be equally included in the patent protection scope of the present application.
