[0002] In family life, the tedious housework occupies a lot of time and energy, and the cleaning device emerges as the times require in such a background. In the existing cleaning device, the cleaning mechanism and the equipment main body of the cleaning device are connected in the way of a swing rod. In the working state, the cleaning mechanism is respectively abutted with the ground to be cleaned and the transmission slope under the action of gravity, so as to realize the cleaning of the ground to be cleaned and the transmission of the cleaning object to the storage box by the transmission slope. However, since the transmission slope supports the cleaning mechanism greatly, it greatly affects the dynamic pressure of the cleaning mechanism on the ground to be cleaned, resulting in poor cleaning ability of the cleaning device, which cannot meet the family cleaning demand.

[0014] The present application will be further described below in conjunction with the drawings and embodiments. It is particularly pointed out that the following embodiments are only for illustrating the present application, but not for limiting the scope of the present application. Similarly, the following embodiments are only part of the embodiments of the present application, but not all the embodiments of the present application, and all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0015] Reference to "embodiments" in this application means that the specific features, structures or characteristics described in conjunction with the embodiments can be included in at least one embodiment of the present application. It is explicitly and implicitly understood by those skilled in the art that the embodiments described in the present application can be combined with other embodiments.

[0016] The present application provides a cleaning device 1, as shown in Figure 1 and Figure 2 The cleaning device 1 includes a device body 20 and a cleaning mechanism 10, and the device body 20 is provided with a transmission slope 23. In some embodiments, the device body 20 is provided with a movement mechanism, such as a wheel body 30, etc., so that the cleaning device 1 as a whole can move on the cleaning area of the floor 2 to be cleaned, such as the living room floor, the guest room floor, the kitchen floor, etc. The cleaning mechanism 10 abuts against the floor 2 to be cleaned to clean the floor 2 to be cleaned, and the cleaning mechanism 10 also abuts against the front side of the transmission slope 23 to cooperate with the transmission slope 23 to transmit the cleaning objects such as garbage and stains on the floor to be cleaned to the rear side of the transmission slope 23, such as to the storage box 40 at the rear side of the transmission slope 23, so as to effectively simplify the overall structure of the cleaning device 1, and effectively improve the transmission efficiency of the cleaning device 1 for the cleaning objects such as garbage and stains. It should be noted that when the cleaning device 1 is placed on the floor 2 to be cleaned, the transmission slope 23 is inclined relative to the floor 2 to be cleaned, wherein the front side of the transmission slope 23 is defined as the side with a larger inclination angle of the transmission slope 23 relative to the floor 2 to be cleaned, and the rear side of the transmission slope 23 is defined as the side with a smaller inclination angle of the transmission slope 23 relative to the floor 2 to be cleaned.

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

[0018] Furthermore, in the working state (i.e., when the cleaning device 1 is cleaning the floor to be cleaned 2), the cleaning belt 13 exerts a first dynamic pressure on the floor to be cleaned 2, thereby enabling the cleaning belt 13 to clean the floor to be cleaned 2. Furthermore, in the working state, the cleaning belt 13 exerts a fourth dynamic pressure on the transmission ramp 23, thereby enabling the cleaning belt 13 to more efficiently cooperate with the transmission ramp 23 to transfer the object to be cleaned into the storage box 40, thereby effectively improving the efficiency of the cleaning belt 13 in transferring the object to be cleaned. The first dynamic pressure is the dynamic pressure exerted by the cleaning belt 13 on the floor to be cleaned 2, supported by the transmission ramp 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 exerted by the cleaning mechanism 10 on the transmission ramp 23 (i.e., the fourth dynamic pressure), and the dynamic force exerted by the cleaning mechanism 10 on the device body 20. Specifically, the force analysis of the cleaning mechanism 10 can be performed through theoretical mechanics, which will not be described in detail herein.

[0019] Specifically, if Figure 2 As shown, in this embodiment, the cleaning mechanism 10 is connected to the device body 20 in a swing arm manner. In other words, the cleaning mechanism 10 can swing relative to the device body 20 about the third axis z3. For example, in some embodiments, the cleaning mechanism 10 can be a cantilever structure, disposed on the device body 20, so that the cleaning mechanism 10 as a whole can swing about the third axis z3 toward the transmission ramp 23 under the action of its own gravity, thereby pressing the cleaning belt 13 against the floor 2 to be cleaned and the transmission ramp 23, thereby cleaning the floor 2 to be cleaned.

[0020] Alternatively, as Figure 2As shown, in some embodiments, the roller mechanism 15 comprises a first roller 11, a second roller 12 and a linkage assembly 14, the linkage assembly 14 comprises a first end and a second end arranged oppositely, the first roller 11 is rotatably supported at the first end of the linkage assembly 14 and can rotate around a first axis z1, the second roller 12 is rotatably supported at the second end of the linkage assembly 14 and can rotate around a second axis z2 which is parallel to the first axis z1, the linkage assembly 14 is rotatably supported on the device main body 20, so that the cleaning mechanism 10 is arranged on the device main body 20 in a swing rod manner. The cleaning belt 13 is arranged in a ring shape around the periphery of the first roller 11 and the second roller 12, and is pressed against the ground 2 to be cleaned by the second roller 12. The first axis z1 is arranged perpendicular to the advancing direction X1 of the cleaning device 1.

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

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

[0023] In optional embodiments, the distance between the third axis z3 and the first axis z1 is less than the radius of the first roller 11.

[0024] Optionally, as Figure 3As shown, in some embodiments, the first axis z1, the second axis z2 and the third axis z3 are spaced apart from each other, wherein the third axis z3 can be arranged in parallel with the first axis z1, or the third axis z3 can be arranged at an angle with the first axis z1. For example, in some embodiments, the roller mechanism 15 further comprises a connecting member 16, one end of the connecting member 16 is fixedly connected with the connecting rod assembly 14, and the other end of the connecting member 16 is rotatably connected with the device body 20, so that the cleaning mechanism 10 as a whole is connected with the device body 20 in a swing rod manner. In this way, the cleaning mechanism 10 as a whole is in a single cantilever structure and is suspended on the device body 20, so that the roller mechanism 15 as a whole can press and hold the cleaning belt 13 on the to-be-cleaned ground 2 and the transmission slope 23 by 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, 22 mm, 21 mm, 20 mm, or 19 mm, or any actual value less than or equal to 22 mm. Under the premise of meeting the structural strength, the structural size of the first roller 11 can be as small as possible, which is conducive to the miniaturization of the cleaning device. In some embodiments, the radial dimension of the second roller 12 is between 48 mm and 77 mm, for example, 48 mm, 49 mm, 50 mm, 55 mm, or 77 mm, or any actual value between 48 mm and 77 mm. In this way, the cleaning device 1 can clean to-be-cleaned objects with larger structural sizes, 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, 1600 g, 1650 g, 1750 g, or 2000 g, or any value between 1600 g and 2000 g. In this way, it can effectively ensure that the cleaning belt 13 has a large enough first dynamic pressure on the to-be-cleaned ground 2, while ensuring that the to-be-cleaned ground has a large enough dynamic pressure on the transmission slope 23, thereby effectively ensuring the cleaning efficiency and cleaning ability of the cleaning device 1.

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

[0029] In particular, the dynamic pressure is the pressure of the cleaning device 1 acting on the ground 2 to be cleaned in the working state. During the working process, a larger dynamic pressure is beneficial to improve the cleaning efficiency and cleaning capacity of the cleaning belt 13 on the ground 2 to be cleaned. The second dynamic pressure is the dynamic pressure of the cleaning belt 13 acting directly on the ground 2 to be cleaned without the support of the transmission slope 23. Since the gravity of the cleaning mechanism 10 is constant, under the same conditions, the greater the support of the transmission slope 23 on the cleaning mechanism 10 (i.e., the greater the dynamic pressure of the cleaning mechanism 10 on the transmission slope 23), the smaller the force of the corresponding cleaning mechanism 10 on the ground 2 to be cleaned, i.e., the first dynamic pressure. On the contrary, the greater the support of the ground 2 to be cleaned on the cleaning mechanism 10 (i.e., the greater the first dynamic pressure of the cleaning mechanism 10 on the ground 2 to be cleaned), the smaller the dynamic pressure of the corresponding cleaning mechanism on the transmission slope 23. 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 slope 23 are negatively correlated. Under the same conditions, the first dynamic pressure is smaller 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 slope 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 capacity and cleaning efficiency of the cleaning belt 13 on 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 and the dynamic pressure of the cleaning belt 13 on the transmission slope 23 is small, which will affect the transmission efficiency of the cleaning belt 13 cooperating with the transmission slope 23 to transmit the cleaning object. Therefore, the ratio of the first dynamic pressure value to the second dynamic pressure value is set to be between 0.3 and 0.8, for example, the ratio can be 0.3, 0.4, 0.5, 0.55, 0.6, 0.7 or 0.8, etc. Any value between 0.3 and 0.8, so that the pressure distribution of the cleaning belt 13 on the ground 2 to be cleaned and on the transmission slope 23 is more reasonable, thereby effectively improving the cleaning capacity 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, which can effectively ensure the dynamic pressure of the cleaning belt 13 on the ground 2 to be cleaned (i.e., the first dynamic pressure), thereby effectively ensuring the cleaning capacity of the cleaning device 1.

[0032] Optionally, in some embodiments, the first dynamic pressure is between 300-700 grams, such as 300 grams, 310 grams, 350 grams, 400 grams, or 700 grams, and the like, so as to effectively ensure the cleaning ability of the cleaning belt 13 to the ground 2 to be cleaned, thereby effectively ensuring the cleaning ability of the cleaning device 1. It should be noted that in some embodiments herein, the commonly used weight unit, i.e. "grams, g", is used to represent the size of the dynamic pressure, which can be converted into Newton force unit through Newtonian mechanics formula, for example, 300g = 0.3kg x 9.8N / kg = 2.94N.

[0033] Optionally, in some embodiments, the size relationship between the first dynamic pressure and the dynamic pressure of the cleaning belt 13 to the transmission slope 23 can be adjusted by adjusting the proportion 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 slope 23, so as to ensure that the cleaning belt 13 has a large enough first dynamic pressure to the ground 2 to be cleaned, and at the same time, the cleaning ground has a large enough dynamic pressure to the transmission slope 23, thereby effectively ensuring the cleaning ability of the cleaning device 1, and at the same time, effectively improving the transmission efficiency of the cleaning belt 13 cooperating with the transmission slope 23 to transmit the cleaning object.

[0034] Specifically, as shown in Figure 2 In some embodiments, the device body 20 is provided with a wheel body 30, and in some embodiments, the device body 20 includes a main frame 21, and the wheel body 30 is arranged on the main frame 21. The wheel body 30 is used to define a support surface in contact with the ground 2 to be cleaned, and the device body 20 is supported on the ground 2 to be cleaned through the wheel body 30, so as to move along the direction of travel 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 surface of the bottom ends of the four wheel bodies 30. After the cleaning device 1 is placed on the ground 2 to be cleaned, the support surface will be in contact with or overlap with the ground 2 to be cleaned. Wherein, if the ground 2 to be cleaned is a plane, 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] Referring to Figure 4 to Figure 5In the reference section a-a perpendicular to the support surface and parallel to the advancing direction X1, the greater the width K1 of the contact surface formed by the cleaning belt 13 pressing against the ground 2 to be cleaned, the greater the area of the contact surface formed by the cleaning belt 13 pressing against the ground 2 to be cleaned, and the greater the width K2 of the transmission slope 23, and in order to ensure that the cleaning belt 13 can smoothly cooperate with the transmission slope 23 to transport the object to be cleaned, the greater the area of the contact surface of the cleaning belt 13 with the transmission slope 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 slope is too small in the reference section a-a perpendicular to the support surface, the area of the contact surface formed by the cleaning belt 13 pressing against the ground 2 to be cleaned is relatively small relative to the area of the contact surface of the cleaning belt 13 with the transmission slope 23, thereby resulting in that the first dynamic pressure is 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 slope is too large in the reference section a-a perpendicular to the support surface, the area of the contact surface formed by the cleaning belt 13 pressing against the ground 2 to be cleaned is relatively large relative to the area of the contact surface of the cleaning belt 13 with the transmission slope 23, thereby resulting in that the dynamic pressure of the cleaning belt 13 acting on the ground 2 to be cleaned per unit area is too small, which is not conducive to the cleaning of the ground 2 to be cleaned by the cleaning belt 13, and also results in that the fourth dynamic pressure of the cleaning belt 13 on the transmission slope 23 is too small, which is not conducive to the cooperation of the cleaning belt 13 with the transmission slope 23 to transport the object to be cleaned. Therefore, 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 slope is between 0.25 and 0.30, for example, 0.25, 0.26, 0.27, or 0.30, and other actual values between 0.25 and 0.30, which can make the distribution ratio of the first dynamic pressure and the fourth dynamic pressure more reasonable, and also effectively ensure the dynamic pressure of the cleaning belt 13 acting on the ground 2 to be cleaned per unit area, thereby effectively improving the cleaning ability of the cleaning device 1.

[0036] In optional embodiments, due to the different materials of the ground 2 to be cleaned, the friction between the cleaning belt 13 and the ground to be cleaned is directly affected, and due to the cantilever structure of the cleaning mechanism 10, the dynamic pressure on the ground to be cleaned, i.e., the first dynamic pressure, is also affected.

[0037] Optionally, as Figure 6As shown, in some embodiments, on the side of the first roller 11 and / or the second roller 12 towards the conveying slope 23, the first roller 11 and the second roller 12 have a common tangent DE, specifically, the first roller 11 has a reference point D, and the second roller 12 has a reference point E, wherein 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] The positional relationship between the common tangent DE and the conveying slope 23 directly affects whether the cleaning mechanism 10 can better distribute the dynamic pressure of the cleaning belt 13 on the to-be-cleaned ground 2 and the conveying slope 23. Since the cleaning mechanism 10 is connected to the equipment main body 20 in a swing rod manner, the positional relationship between the cleaning mechanism 10 and the conveying slope 23 changes with the change of the spatial state of the cleaning device 1, thereby causing the positional relationship between the common tangent DE and the conveying slope 23 to change, and further causing the included angle J1 between the common tangent DE and the line connecting the upper end and the lower end of the conveying slope 23 to change. For example, when the cleaning device 1 is in a suspended state, at this time, the cleaning mechanism 10 is not supported by the to-be-cleaned ground 2, and the cleaning mechanism 10 is arranged closer to the conveying slope 23 under the action of gravity, at this time, the included angle J1 between the common tangent DE and the line connecting the upper end and the lower end of the conveying slope 23 is maximum, and for example, compared with the cleaning device 1 in the suspended state, when the cleaning device 1 is placed on the ground, the to-be-cleaned ground 2 supports the cleaning mechanism 10, so that the cleaning mechanism 10 swings in a direction away from the conveying slope 23 by a certain angle, thereby reducing the included angle J1 between the common tangent DE and the line connecting the upper end and the lower end of the conveying slope 23.

[0039] In addition, the cleaning belt 13 described in the present application can be in three states: one, a factory state, at this time, the cleaning belt 13 is in a factory state, and the cleaning belt 13 is not soaked by liquid, at this time, the wool layer 132 (as shown in Figure 8 ) is relatively fluffy, when it is pressed on the to-be-cleaned ground 2, there is a relatively large deformation; two, a running state, the running state is after 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 soaked by liquid, at this time, the wool layer 132 is relatively compacted, when the wool layer 132 is pressed on the to-be-cleaned ground 2, the degree of deformation is relatively reduced; three, a soaking state, the soaking state refers to a state that the cleaning belt 13 is soaked by liquid after moving in a fixed direction for at least 5 hours, at this time, when the wool layer 132 is pressed on the to-be-cleaned ground 2, the degree of deformation is further reduced.

[0040] Therefore, the included angle J1 between the common tangent DE and the line connecting the upper end and the lower end of the conveying slope 23 also changes with the change of the working state of the cleaning device 1.

[0041] Optionally, as shown in Figure 6As shown, in some embodiments, compared with the cleaning mechanism 10 being in a suspended state, when the cleaning belt 13 is pressed against the floor 2 to be cleaned, the angle J1 between the common tangent DE and the line connecting the upper and lower ends of the transmission slope 23 changes by 0.8° to 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 floor 2 to be cleaned, but there is a low-lying area on the floor 2 to be cleaned, resulting in the cleaning mechanism 10 being unable to contact the floor 2 to be cleaned. In this state, the cleaning belt 13 presses against the transmission ramp 23 but does not press against the floor 2 to be cleaned. The positional relationship between the cleaning mechanism 10 and the transmission ramp 23 is also referred to as the second positional relationship. When the cleaning mechanism 10 is in contact with the floor 2 to be cleaned, the cleaning belt 13 presses against the floor 2 to be cleaned. The positional relationship between the cleaning mechanism 10 and the transmission ramp 23 is also referred to as the third positional relationship.

[0043] like Figure 6 As shown, the upper end of the transmission slope 23 has a reference point F intersecting with the reference section aa, and the lower end of the transmission slope 23 has a reference point H intersecting with the reference section aa, wherein the line connecting the upper and lower ends of the transmission slope 23 described in this article is the line FH.

[0044] When the cleaning mechanism 10 is in a suspended state, the bottom of the cleaning belt 13 is located below the supporting surface. When the cleaning mechanism 10 is in contact with the floor 2 to be cleaned, the supporting surface contacts the floor 2 to be cleaned, and the floor 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 surface 23 around the first axis z1 (that is, causing the second roller 12 to be lifted a certain distance relative to the floor 2 to be cleaned), thereby causing the angle J1 to change. For example, in this embodiment, compared to when the cleaning mechanism 10 is in a suspended state, when the cleaning belt 13 presses against the floor 2 to be cleaned, the angle J1 decreases. Of course, when the cleaning device 1 is in an operating state, when the cleaning mechanism 10 cleans the object to be cleaned, it is pushed against the object to be cleaned, causing the cleaning mechanism 10 to swing a certain distance away from the transmission inclined surface 23 around the first axis z1, thereby causing the angle J1 to change. During this process, the angle J1 also tends to decrease.

[0045] When the cleaning belt 13 is pressed 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 slope 23 cannot be in good contact with the transmission slope 23, thereby affecting the transmission efficiency of the cleaning belt 13 cooperating with the transmission slope 23 to transmit the material 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 slope 23 is too large, thereby 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°, for example, 0.8°, 1.5°, 1.6°, 2°, 3° or 4°, which is an actual value between 0.8° and 4.0°. This can effectively ensure that the first dynamic pressure is large enough, and also effectively ensure that the cleaning belt 13 is in full contact with the transmission slope 23, thereby effectively improving the cleaning ability and cleaning efficiency of the cleaning device 1. It should be noted that in the scheme of the embodiment, no matter what state the cleaning belt 13 is in, compared with the cleaning mechanism 10 in the suspended state, when the cleaning belt 13 is pressed against the ground 2 to be cleaned, the angle change amount of the included angle J1 between the common tangent DE and the upper and lower ends of the transmission slope 23 is between 0.8° and 4.0°.

[0046] Optionally, as shown in some embodiments, Figure 2 and Figure 6 The device body 20 includes a main frame 21 and a guide 22 arranged on the main frame 21. The main frame 21 is formed with a first transmission slope 211, and the guide 22 is formed with a second transmission slope 221. The first transmission slope 211 and the second transmission slope 221 are connected to form a transmission slope 23. The guide 22 is arranged at the lower end of the first transmission slope 211 to guide the material to be cleaned on the ground 2 to be cleaned to the first transmission slope 211, thereby effectively ensuring that the cleaning belt 13 can efficiently guide the material to be cleaned into the first transmission slope 211. The first roller 11 and one end of the connecting rod assembly 14 are rotatably supported on the main frame 21, so that the cleaning mechanism 10 is connected to the device body 20 in a swing lever manner. In the working state, the cleaning belt 13 is pressed by the second roller 12 and the gravity of the roller mechanism 15 to the ground 2 to be cleaned, the first transmission slope 211 and the second transmission slope 221.

[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 slope 23 described in the content of the present document includes the dynamic pressure of the cleaning belt 13 (or the cleaning mechanism 10) on the first transmission slope 211 and the dynamic pressure on the second transmission slope 221.

[0048] Optionally, as shown in some embodiments, Figure 6As shown, in some embodiments, in the reference section a-a perpendicular to the support surface, the first transmission slope 211 has a first connecting line FG between the lower end of the first transmission slope 211 and the upper end of the first transmission slope 211, and the common tangent DE is also referred to as the common tangent DE between the first roller 11 and / or the second roller 12 towards the side of the first transmission slope 211, between the first roller 11 and the second roller 12. Specifically, the upper end of the first transmission slope 211, i.e. the upper end of the transmission slope 23, has a reference point F intersecting the reference section a-a, and the lower end of the first transmission slope 211 has a reference point G intersecting the reference section a-a, wherein the connecting line between the reference point F and the reference point G is the first connecting line FG.

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

[0050] Specifically, since the gravity of the cleaning mechanism 10 is certain, under the same conditions, the greater the supporting effect of the first transmission slope 211 on the cleaning mechanism 10 (i.e., the greater the dynamic pressure of the cleaning mechanism 10 on the first transmission slope 211), the smaller the corresponding force of the cleaning mechanism 10 on the to-be-cleaned ground 2, i.e., the first dynamic pressure, and vice versa. Therefore, the cleaning mechanism 10 needs not only to maintain abutment with the first transmission slope 211, but also to maintain abutment with the to-be-cleaned ground 2 in the working state, so as to ensure that the cleaning belt 12 cooperates with the first transmission slope 211 to transmit the to-be-cleaned object with high transmission efficiency, and at the same time, the to-be-cleaned ground 2 can be efficiently cleaned. When the cleaning belt 13 contacts the first transmission slope 211, the common tangent DE is gradually arranged away from the first line FG along the extension direction X2, so that in the working state, the common tangent DE is gradually arranged away from the first line FG along the extension direction X2, and then the first transmission slope 211 has at least three contact relationships with the cleaning belt 13 in turn, which are respectively "the first transmission slope 211 contacts the cleaning belt 13, and there is interference between the first transmission slope 211 and the cleaning belt 13, and the first transmission slope 211 supports the cleaning belt 13 to support the cleaning mechanism 10", "the first transmission slope 211 contacts the cleaning belt 13, and there is no interference or small interference between the first transmission slope 211 and the cleaning belt 13, and the first transmission slope 211 does not support the cleaning belt 13 or supports the cleaning belt 13 with small supporting effect", and "the first transmission slope 211 is arranged away from the cleaning belt 13, and indirectly contacts the cleaning belt 13 through the vibration effect of the cleaning belt 13 in operation", which can effectively reduce the contact area of the first transmission slope 211 on the cleaning mechanism 10 in the working state, thereby reducing the supporting effect, and thereby effectively improving the first dynamic pressure of the cleaning belt 13 on the to-be-cleaned ground 2 under the premise of ensuring the dynamic pressure of the cleaning belt 13 on the first transmission slope 211.

[0051] And, referring to Figure 2As shown, in some embodiments, the cleaning device 1 further comprises a receiving box 40, which is provided with a receiving space 41 for receiving the to-be-cleaned objects, and the receiving box 40 is detachably arranged on the main frame, and the receiving box 40 is arranged at the rear side of the first conveying slope 211 (the definition of the front side and the rear side of the first conveying slope 211 can refer to the definition of the front side and the rear side of the conveying slope 23 described above, which will not be described in detail here), and the upper end of the first conveying slope 211 and the cleaning belt form a flow outlet 231, and the flow outlet 231 is in communication with the receiving space 41, and the to-be-cleaned objects flowing from the to-be-cleaned ground 2 to the first conveying slope 211 can flow into the receiving space 41 along the flow outlet 231. Wherein, in the case that the distance between the first roller 11 and the second roller 12 is constant, the relative position relationship between the common tangent DE and the first line FG, that is, along the extension direction X2, the common tangent DE is gradually arranged away from the first line FG, so that the distance between the upper end of the first conveying slope 211 and the first roller 11 and the cleaning belt 13 is farther, thereby effectively improving the size of the flow outlet 231, so that the to-be-cleaned objects can be smoothly guided from the flow outlet 231 into the receiving box 40. It should be noted that in the scheme of the present embodiment, no matter what state the cleaning belt 13 is in, when the cleaning belt 13 is in contact with the first conveying slope 211, along the extension direction X2 of the second roller 12 towards the first roller 11, the common tangent DE is always arranged gradually away from the first line FG.

[0052] When the cleaning belt 13 is in contact with the first conveying slope 211, there is not necessarily a pressing between the cleaning belt 13 and the first conveying slope 211, that is, there is not necessarily an interaction force between the cleaning belt 13 and the first conveying slope 211. In other words, when the cleaning mechanism 10 is in contact with the first conveying slope 211 (that is, when the cleaning belt 13 is in contact with the first conveying slope 211), the relative position relationship between the cleaning mechanism 10 and the first conveying slope 211 includes at least three special position relationships.

[0053] The first position relationship is that the cleaning mechanism 10 is in contact with the first conveying slope 211, and the interaction force between the cleaning mechanism 10 and the first conveying slope 211 is not enough to make the cleaning belt 13 deform again (it should be noted that before the cleaning belt 13 is in contact with the first conveying 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 conveying slope 211, but is formed under the action of gravity), at this time the cleaning belt 13 contacts the first conveying slope 211 in a non-deformation manner, which may require external force to achieve this relationship.

[0054] The second position relationship is that the cleaning belt 13 is pressed against the first transmission slope 211, and the cleaning belt 13 is not pressed against the to-be-cleaned ground 2. In this position relationship, the cleaning mechanism 10 is in contact with the first transmission slope 211, and the interaction force between the cleaning mechanism 10 and the first transmission slope 211 causes the cleaning belt 13 to deform again. The second characteristic position relationship can be understood as a state in which the cleaning mechanism 10 is not supported by the to-be-cleaned ground 2, for example Figure 7 As shown in the figure, when the cleaning device 1 is placed on the to-be-cleaned ground, the cleaning mechanism 10 is in a suspended state, that is, a state in which the to-be-cleaned ground 2 does not support the cleaning mechanism 10. Of course, in some embodiments, this state can also be a state in which the entire cleaning device 1 is suspended, and the bottom of the cleaning device 1 is directed to the to-be-cleaned ground 2.

[0055] The third position relationship is that Figure 2 As shown in the figure, when the cleaning mechanism 10 is in contact with the to-be-cleaned ground, the cleaning mechanism 10 is pressed against the first transmission slope 211, and the cleaning mechanism 10 is pressed against the to-be-cleaned ground 2 (or in some embodiments, the cleaning belt 13 is pressed against the to-be-cleaned ground 2). At this time, the cleaning belt 13 is in contact with the to-be-cleaned ground 2 and the second transmission slope 211 respectively, and there is an interaction force, and the to-be-cleaned ground 2 and the second transmission slope 211 jointly support the cleaning mechanism 10.

[0056] In the working state of the cleaning device 1, the relative position relationship between the cleaning mechanism 10 and the first transmission slope 211 is in the third position relationship. Of course, in extreme working conditions, the third position relationship changes to the second position relationship. For example Figure 7 As shown in the figure, when the cleaning device 1 moves to a pothole, the cleaning mechanism 10 cannot be in contact with the to-be-cleaned ground 2. At this time, the cleaning mechanism 10 swings in the direction of the first transmission slope 211 around the first axis z1 under the action of gravity, so that the relative position relationship between the cleaning mechanism 10 and the first transmission slope 211 changes from the third position relationship to the second position relationship.

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

[0058] Alternatively, as Figure 6As shown, in some embodiments, when the cleaning belt 13 contacts the first transmission slope 211 in a non-deformation manner (that is, when the relative position relationship between the cleaning mechanism 10 and the first transmission slope 211 is in a first position relationship), along the extension direction X2, the common tangent DE is gradually set away from the first connecting line FG.

[0059] Specifically, when the relative position relationship between the relative cleaning mechanism 10 and the first transmission slope 211 is in the third position relationship, when the relative position relationship between the cleaning mechanism 10 and the first transmission slope 211 is in the first position relationship, the cleaning mechanism 10 is closer to the first transmission slope 211. Therefore, when the cleaning belt 13 contacts the first transmission slope 211 in a non-deformed manner, the common tangent line DE is gradually set away from the first connection line FG along the extension direction X2 of the second roller 12 toward the first roller 11, which can ensure that in the working state, along the extension direction X2, the common tangent line DE is gradually set away from the first connection line FG, thereby making the first transmission slope 211 have at least three contact relationships with the cleaning belt 13 in sequence, which are "first transmission slope 21 1 is in contact with 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 slope 211 is in contact with the cleaning belt 13, and does not interfere with the cleaning belt 13 or the interference is small, and the first transmission slope 211 does not support the cleaning belt 13 or the supporting effect is small", and "the first transmission slope 211 is in indirect contact with the cleaning belt 13 through the vibration of the cleaning belt 13". This can effectively reduce the supporting effect of the first transmission slope 211 on the cleaning mechanism 10 in the working state, thereby effectively improving the first dynamic pressure of the cleaning belt 13 on the ground surface 2 to be cleaned while ensuring the dynamic pressure of the cleaning belt 13 on the first transmission slope 211 and effective contact.

[0060] Alternatively, as Figure 6 As shown, in some embodiments, when the cleaning belt 13 contacts the first transmission slope 211 in a non-deformed manner, the first angle J2 between the first connecting line FG and the common tangent DE is between 2° and 13°, for example, 2°, 3°, 4°, 7°, 10° or 13°, etc., which are actual values ​​between 2° and 13°. Such a setting can ensure that when in the working state, the first angle J2 between the first connecting line FG and the common tangent DE is within a relatively reasonable range, so as to effectively reduce the supporting effect of the first transmission slope 211 on the cleaning mechanism 10 in the working state, thereby effectively increasing the first dynamic pressure of the cleaning belt 13 on the ground surface 2 to be cleaned while ensuring the dynamic pressure of the cleaning belt 13 on the first transmission slope 211.

[0061] Optionally, in some embodiments, compared to when the cleaning mechanism 10 is in the suspended state (the second positional relationship), when the cleaning belt 13 is pressed against the floor surface 2 to be cleaned, the angular change of the first angle J2 is between 0.5° and 3°. Specifically, the angular change of the first angle J2 when transitioning from the second positional relationship to the third positional relationship can indirectly affect the amount of interference between the cleaning belt 13 and the first transmission inclined surface 211 when the cleaning belt 13 is pressed against the first transmission inclined surface 211 and against the floor surface 2 to be cleaned. Among them, the angular change is positively correlated with the interference between the cleaning belt 13 and the first transmission inclined surface 211. If the interference between the cleaning belt 13 and the first transmission inclined surface 211 is too large, the first transmission inclined surface 211 will have an excessively large supporting effect on the cleaning mechanism 10, thereby weakening the first dynamic pressure of the cleaning belt 13 on the floor 2 to be cleaned, affecting the cleaning ability of the cleaning belt 13 on the floor 2 to be cleaned. If the interference between the cleaning belt 13 and the first transmission inclined surface 211 is too small, the dynamic pressure of the cleaning belt 13 on the first transmission inclined surface 211 will be too small, which is not conducive to the cleaning belt 13 cooperating with the first transmission inclined surface 211 to transport the object to be cleaned. Therefore, in some embodiments, the angular change of the first angle J2 when transitioning from the second positional relationship to the third positional relationship is between 0.5° and 3°, for example, 0.5°, 0.6°, 1°, or 3°, or other actual values ​​between 0.5° and 3°. This effectively ensures that the dynamic pressure of the cleaning belt 13 on the first transmission slope 211 is sufficiently large, thereby effectively ensuring the transmission efficiency of the cleaning belt 13 in cooperating with the first transmission slope 211 in transmitting the object to be cleaned. It can also effectively increase the first dynamic pressure of the cleaning belt 13 on the floor to be cleaned 2, 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 to the state in which the cleaning mechanism 10 is suspended, when the cleaning belt 13 is pressed against the floor to be cleaned 2, the angular change of the first angle J2 is always between 0.5° and 3°.

[0062] Alternatively, as Figure 6 As shown, in some embodiments, a second connecting line GH is defined between the lower end of the second transmission slope 221 and the upper end of the second transmission slope 221. A second angle J5 between the second connecting line GH and the first connecting line FG is between 3° and 11°. Specifically, the upper end of the second transmission slope 221 is connected to the lower end of the first transmission slope 211. Reference point F is the common reference point of the lower end of the first transmission slope 211 and the upper end of the second transmission slope 221. The lower end of the second transmission slope 221 is the lower end of the transmission slope 23. It has a reference point H that intersects with the reference section aa. The line connecting reference point G and reference point H is the second connecting line GH.

[0063] Furthermore, if Figure 4 and Figure 6As shown, the second transmission slope 221 is closer to the second roller 12 than the first transmission slope 211, and the cleaning belt 13 wound around the outer periphery of the second roller 12 is in the shape of a circular arc. Therefore, the second included angle J5 is set to be between 3° and 11°, for example, 3°, 4°, 4.5°, 6°, or 11°, or any actual value between 3° and 11°, so that the second transmission slope 221 is "bent" towards the cleaning belt 13 relative to the first transmission slope 211, so that the transmission slope 23 can better match the outer periphery profile of the cleaning belt 13, so that the cleaning belt 13 can more efficiently cooperate with the guide 22 to guide the to-be-cleaned object of the to-be-cleaned ground 2 to the transmission slope 23, thereby effectively improving the transmission efficiency of the cleaning belt 13 cooperating with the transmission slope 23 to transmit the to-be-cleaned object. Moreover, setting the second included angle J5 to be between 3° and 11° can also effectively ensure that there is a large enough inlet gap 3 between the lower end of the second transmission slope 221 and the cleaning belt 13, thereby ensuring that the cleaning belt 13 can efficiently transmit the to-be-cleaned object to the transmission slope 23 along the inlet gap 3, thereby effectively improving 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, the first reference line Iz2 passes through the second axis z2 and is perpendicular to the support surface at the reference section a-a, the second reference line Gz2 passes through the second axis z2 and the upper end of the second conveying slope 221, and the third reference line Hz2 passes through the second axis z2 and the lower end of the second conveying slope 221, when the cleaning belt 13 contacts the first conveying slope 211 in a non-deformation manner, the included angle J3 between the first reference line Iz2 and the second reference line Gz2 is between 43° and 51°, and the included angle J4 between the first reference line Iz2 and the third reference line Hz2 is between 22° and 27°. Specifically, the value of the included angle J4 will directly affect the size of the infeed gap 3 in the working state, wherein the smaller the included angle J4, the smaller the infeed gap 3, and the larger the included angle J4, the larger the infeed gap 3, and when the cleaning device 1 is placed on the ground relative to the cleaning belt 13 contacting the first conveying slope 211 in a non-deformation manner, the included angle J4 will be reduced to a certain extent, so the included angle J4 between the first reference line Iz2 and the third reference line Hz2 is set to be between 22° and 27°, for example, 22°, 23°, 24.5° or 27°, and other actual values between 22° and 27°, so as to effectively ensure that the included angle J4 can be within a more reasonable angle range when the cleaning device 1 is placed on the to-be-cleaned ground 2, thereby effectively ensuring that the size of the infeed gap 3 between the lower end of the second conveying 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 convey the to-be-cleaned objects to the conveying slope 23 along the infeed gap 3, thereby effectively improving the cleaning capacity of the cleaning device 1. Further, the upper end of the second conveying slope 221 is the connecting end of the first conveying slope 211, so the upper end of the second conveying slope 221 is one of the turning points of the conveying slope 23, under the condition that the second included angle J5 is constant, the included angle J3 will directly affect the matching degree of the conveying slope 23 and the outer contour of the cleaning belt 13 and the size of the infeed gap 3, thereby directly affecting the transmission efficiency of the cleaning belt 13 cooperating with the conveying slope 23 to convey the to-be-cleaned objects and the guiding efficiency of the cleaning belt to guide the to-be-cleaned objects to the conveying slope 23.

[0065] And, relative to the cleaning belt 13 contacts the first conveying slope 211 in a non-deformation manner, when the cleaning mechanism 10 is in abutment with the ground 2 to be cleaned, the included angle J3 will be reduced to a certain extent, and the included angle J3 is set to be between 43°-51° when the cleaning belt 13 contacts the first conveying slope 211 in a non-deformation manner, for example, 43°, 43.5°, 45°, 48° or 51°, etc. The actual value between 43°-51°, so as to effectively ensure that the cleaning device 1 placed on the ground 2 to be cleaned, the included angle J3 can be within a reasonable angle range, thereby effectively ensuring that the conveying slope 23 and the outer contour of the cleaning belt 13 have a higher matching degree and the size of the inlet gap 3 is more reasonable, thereby effectively improving the conveying efficiency of the cleaning belt 13 cooperating with the conveying slope 23 to convey the cleaning object, and also enabling the cleaning belt 13 to more efficiently guide the cleaning object to the conveying slope 23, thereby effectively improving the cleaning ability of the cleaning device 1.

[0066] Optionally, as shown in Figure 2 and Figure 6 shown, in some embodiments, when the cleaning belt 13 is pressed against the ground 2 to be cleaned, the vertical distance L1 between the upper end of the first conveying slope 211 and the common tangent DE is between 6.5mm-8.0mm, for example, 6.5mm, 7mm or 8.0mm, etc. The actual value between 6.5mm-8.0mm. Specifically, if the vertical distance L1 between the upper end of the first conveying slope 211 and the common tangent DE is too small, it will easily cause the cleaning object to be stuck between the upper end of the first conveying slope 211 and the cleaning belt 13, thereby causing the cleaning device 1 to not work normally, and if the vertical distance L1 is too large, it will easily cause the cleaning belt 13 to not contact the area near the upper end of the first conveying slope 211 in the working state, thereby causing the cleaning belt 13 to not efficiently guide the cleaning object into the receiving box 40 in cooperation with the first conveying slope 211. Therefore, the structure size of the flow outlet 231 between the upper end of the first conveying slope 211 and the cleaning belt 13 is more reasonable, so that the cleaning device 1 can clean larger cleaning objects, thereby effectively improving the cleaning ability of the cleaning device 1. And, this setting can also ensure that the cleaning belt 13 can maintain contact with the area near the upper end of the first conveying slope 211 in the working state, thereby effectively improving the conveying efficiency of the cleaning belt 13 cooperating with the conveying slope 23 to convey the cleaning object. It should be noted that when the cleaning belt 13 is pressed against the ground 2 to be cleaned, the cleaning device 1 is in a state of being placed on the ground 2 to be cleaned.

[0067] Optionally, as shown in Figure 2 and Figure 6As shown, in some embodiments, the vertical projection of the upper end of the first transmission slope 211 to the common tangent DE is located between the upper end of the common tangent DE and the lower end of the common tangent DE, which is configured to make the first transmission slope 211 overlap the area between the upper end and the lower end of the common tangent DE as much as possible, so as to ensure that the cleaning belt 13 can be in contact with the first transmission slope 211 as much as possible (it should be noted that the contact here does not necessarily mean force, and the contact relationship between the first transmission slope 211 and the cleaning belt 13 can be referred to the above-mentioned embodiments), thereby effectively improving the efficiency of the cleaning belt 13 cooperating with the first transmission slope 211 to transport the to-be-cleaned objects.

[0068] Optionally, in some embodiments, the distance from the projection point T formed by the vertical projection of the upper end of the first transmission slope 211 to the common tangent DE to the upper end of the common tangent DE is between 0.40 and 0.49 times the length of the common tangent DE, for example, 0.40, 0.41, 0.42, or 0.49, and the like, which is configured to make the distance between the upper end of the first transmission slope 211 and the first roller 11 and the cleaning belt 13 more reasonable, so that the first transmission slope 211 can be in contact with the cleaning belt 13 as much as possible, while effectively reducing the interference of the first roller 11 to the flow outlet 231, thereby effectively improving the transmission efficiency of the cleaning belt 13 cooperating with the first transmission slope 211 to transport the to-be-cleaned objects, and effectively improving the cleaning capacity of the cleaning device 1.

[0069] Optionally, as Figure 8 As shown, in some embodiments, the cleaning belt 13 comprises a base layer 131 and a fluff layer 132 arranged on the outer circumferential surface of the base layer 131, and when the cleaning belt 13 is pressed against the to-be-cleaned ground 2, the ratio of the maximum interference amount of the transmission slope 23 to 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 the present application refers to the length of the fluff in the state of not being abraded and being naturally stretched. It should be noted that in the description of the present application, the interference amount of any component to the fluff layer 132 refers to the difference between the fluff length L2 of the fluff layer 132 and the distance between the component and the base layer 131. 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 to the fluff layer 132 is the difference between the fluff length L2 of the fluff layer 132 and the distance between the corresponding position of the component and the base layer 131. For example, the interference amount of the transmission slope 23 to the fluff layer 132 is the difference between the fluff length L2 of the fluff layer 132 and the distance between each position of the transmission slope 23 and the base layer 131.

[0071] The maximum interference of the transmission slope 23 to the pile layer 132 is the pile length L2 of the pile layer 132 minus the shortest distance corresponding to the shortest distance from the base layer 131 to the transmission slope 23.

[0072] In the embodiment, the shortest vertical distance between the base layer 131 and the transmission slope 23 is located at the area of the transmission slope 23 close to the ground 2 to be cleaned, for example, the area close to the junction of the first transmission slope 211 and the second transmission slope 221. In addition, the ratio of the maximum interference of the transmission slope 23 to the pile layer 132 to the pile length L2 directly affects the dynamic pressure (i.e., the fourth dynamic pressure) of the cleaning belt 13 to the transmission slope 23. If the ratio is too large, the dynamic pressure of the cleaning belt 13 to the transmission slope 23 will increase, thereby weakening the first dynamic pressure. If the ratio is too small, the dynamic pressure of the cleaning belt 13 to the transmission slope 23 will be affected, thereby affecting the transmission efficiency of the cleaning belt 13 in transporting the objects to be cleaned. Therefore, the ratio of the maximum interference of the transmission slope 23 to the pile layer 132 to the pile length L2 is set to be between 0.19 and 0.60, for example, 0.19, 0.20, 0.40, or 0.60, and the like. The pressure distribution of the cleaning belt 13 to the ground 2 to be cleaned and to the transmission slope 23 is more reasonable, thereby effectively improving the cleaning efficiency and cleaning capacity of the cleaning device 1.

[0073] It should be noted that the pile length L2 is constant regardless of the state of the cleaning belt 13. However, the interference of the transmission slope 23 to the pile layer 132 changes when the cleaning belt 13 is pressed against the ground 2 to be cleaned. Therefore, the ratio of the maximum interference of the transmission slope 23 to the pile layer 132 to the pile length L2 of the pile layer 132 also changes when the cleaning belt 13 is pressed against the ground 2 to be cleaned. However, in the embodiment, the ratio is always between 0.19 and 0.60 regardless of the state of the cleaning belt 13 when the cleaning belt 13 is pressed against the ground 2 to be cleaned.

[0074] Optionally, in some embodiments, the pile length L2 of the pile layer 132 is between 6 mm and 8 mm, for example, 6 mm, 6.5 mm, 7 mm, or 8 mm, and the like. Such a setting can effectively ensure the sweeping area of the cleaning belt 13, thereby effectively ensuring the transmission efficiency of the cleaning belt 13 in transporting the objects to be cleaned in cooperation with the transmission slope 23.

[0075] Optionally, in some embodiments, the pile weight of the pile layer 132 is 550-700 g / m2, for example, 550 g / m2, 560 g / m2, 600 g / m2, or 700 g / m2, or any actual value between 550 g / m2and 700 g / m2, which can effectively increase the kinetic energy of the rotating cleaning belt 13, thereby effectively improving the cleaning ability of the cleaning belt 13 on the to-be-cleaned ground 2 and the transmission ability of the cleaning belt 13 in cooperation with the transmission slope 23.

[0076] It should be noted that the pile length L2of the pile layer 132 and the pile weight of the pile layer 132 refer to the pile length and the pile weight of the pile layer 132 when the cleaning belt 13 is shipped.

[0077] Optionally, in some embodiments, when the cleaning belt 13 is pressed against the to-be-cleaned ground 2 and is in the rotating process (i.e., in the working state), the first transmission slope 211 interferes with the pile layer 132 between the lower end and the upper end of the first transmission slope 211, which can effectively improve the transmission efficiency of the cleaning belt 13 in cooperation with the first transmission slope 211.

[0078] Optionally, in some embodiments, when the cleaning belt 13 is pressed against the to-be-cleaned ground 2 and is in the stationary state, the upper end of the first transmission slope 211 is spaced apart from the outer circumferential surface of the pile layer 132, and during the rotating process of the cleaning belt 13, the first transmission slope 211 interferes with the pile layer 132 through the vibration of the cleaning belt 13. Specifically, when the cleaning belt 13 is pressed against the to-be-cleaned ground 2 and is in the stationary state, the upper end of the first transmission slope 211 and the region of the first transmission slope 211 close to the upper end thereof can not interfere with or contact the pile layer 132, i.e., the upper end of the first transmission slope 211 is spaced apart from the outer circumferential surface of the pile layer 132. When the cleaning belt 13 rotates, the rotation of the cleaning belt 13 causes the pile layer 132 to vibrate or swing, thereby causing the pile layer 132 to interfere with the upper end and the lower end of the first transmission slope 211. This not only effectively improves the transmission efficiency of the cleaning belt 13 in cooperation with the first transmission slope 211, but also effectively reduces the support of the first transmission slope 211 on the cleaning mechanism 10, thereby effectively improving the first dynamic pressure, and thus effectively improving the cleaning ability of the cleaning belt 13 on the to-be-cleaned ground 2.

[0079] Optionally, in some embodiments, the base layer 131 is a flexible base layer, and at least part of the cleaning belt 13 between the first transmission slope 211 and the linkage assembly 14 is spaced apart from the linkage assembly 14 thereof, so that the cleaning belt 13 thereof can vibrate back and forth along a direction perpendicular to the cleaning belt 13 during the rotating process, thereby causing the pile layer 132 to interfere with the upper end of the first transmission slope 211.

[0080] In the optional embodiment, the interference between the fluff layer 132 and the lower end and the upper end of the first conveying slope 211 can also be realized by the direct pressing of the cleaning belt 13 onto the first conveying slope 211 and by the vibration of the cleaning belt 13, so as to ensure the contact of the cleaning belt 13 with the first conveying slope 211.

[0081] Optionally, in some embodiments, the ratio of the interference amount of the lower end of the first conveying slope 211 to the fluff layer 132 to the interference amount of the upper end of the first conveying slope 211 to 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 conveying slope 211 to the fluff layer 132 to the interference amount of the upper end of the first conveying slope 211 to the fluff layer 132 can indirectly affect the size of the area of the direct contact of the first conveying slope 211 with the cleaning belt 13, and then affect the first dynamic pressure of the cleaning belt 13 to the cleaning ground 2 and the dynamic pressure of the cleaning belt 13 to the first conveying slope 211, so the ratio is set to be between 1.5 and 10.0, for example, 1.5, 2.0, 8.0 or 10.0 and other actual values between 1.5 and 10.0, which can make the ratio between the first dynamic pressure and the dynamic pressure of the cleaning belt 13 to the first conveying slope 211 more reasonable, so as to effectively improve the cleaning ability of the cleaning belt 13 to the cleaning ground 2, so as to effectively improve the cleaning ability of the cleaning device 1, and also effectively improve the transmission efficiency of the cleaning belt 13 cooperating with the first conveying slope 211 to transmit the cleaning object. It should be noted that, as described above, when the cleaning belt 13 is in a static state, the interference amount of the upper end of the first conveying slope 211 to the fluff layer 132 can be 0, but when the cleaning belt 13 is in a rotating process, the rotation of the cleaning belt 13 causes the fluff layer 132 to vibrate or swing, so that the upper end of the first conveying slope 211 interferes with the fluff layer 132. It should be noted that the fluff length L2 does not change regardless of the state of the cleaning belt 13, but when the cleaning belt 13 is pressed against the cleaning ground 2, the interference amount of the conveying slope 23 to the fluff layer 132 changes under different states, so that when the cleaning belt 13 is pressed against the cleaning ground 2, the ratio of the maximum interference amount of the conveying slope 23 to the fluff layer 132 to the fluff length L2 of the fluff layer 132 also changes, but in the scheme of the embodiment, the ratio of the interference amount of the lower end of the first conveying slope 211 to the fluff layer 132 to the interference amount of the upper end of the first conveying slope 211 to the fluff layer 132 is always between 1.5 and 10.0.

[0082] Optionally, as Figure 2As shown, in some embodiments, the cleaning device 1 further comprises a scraping piece 50 fixedly arranged on the device body 20, wherein the scraping piece 50 is in abutment with the cleaning belt 13 for cleaning the cleaning belt 13 during the movement of the cleaning belt 13. Specifically, during the process that the cleaning belt 13 cleans the floor and cooperates with the transmission slope 23 to transport the to-be-cleaned objects, the cleaning liquid and the to-be-cleaned objects are adhered in the pile layer 132 of the cleaning belt 13, and therefore the scraping piece 50 is arranged so that the scraping piece 50 is in abutment with the cleaning belt 13, that is, the scraping piece 50 extends to the pile layer 132 of the cleaning belt 13, so that the scraping piece 50 can scrape off the cleaning liquid and the to-be-cleaned objects adhered in the pile layer 132 during the rotation of the cleaning belt 13, thereby effectively preventing the cleaning liquid and the to-be-cleaned objects adhered in the pile layer 132 from falling back to the to-be-cleaned floor 2 or splashing into the interior of the cleaning device 1, and further effectively improving the cleaning efficiency and the cleaning capacity of the cleaning device 1.

[0083] Optionally, in some embodiments, the first dynamic pressure and the second dynamic pressure are formed when the scraping piece 50 is in abutment with the cleaning belt 13, that is, the scraping piece 50 is in abutment with the cleaning belt 13 regardless of whether the cleaning mechanism 10 is in the state of being supported by the transmission slope 23 or in the state of not being supported by the transmission slope 23, so that it can be effectively ensured that the scraping piece 50 can still effectively abut against the cleaning belt 13 after the cleaning device 1 is placed on the to-be-cleaned floor, thereby effectively ensuring the cleaning function of the scraping piece 50 on the cleaning belt 13.

[0084] The scraping piece 50 provides certain support for the cleaning mechanism 10, and to some extent, affects the dynamic pressure of the cleaning belt 13 on the to-be-cleaned floor 2 and the transmission slope 23. Therefore, in some embodiments, the ratio of the third dynamic pressure generated by the cleaning belt 13 on the to-be-cleaned floor 2 when the cleaning belt 13 is supported by the transmission slope 23 and the scraping piece 50 is removed to the first dynamic pressure is between 1.07 and 1.80, for example, the ratio can be 1.07, 1.50 or 1.80, or other actual values between 1.07 and 1.80. In this way, when the cleaning device 1 is in the working state, the cleaning mechanism 10 can ensure that the scraping piece 50 has sufficient abutment force, and at the same time, can exert the force on the to-be-cleaned floor 2 and the transmission slope 23 as much as possible, thereby effectively improving the cleaning capacity and the cleaning efficiency of the cleaning mechanism 10.

[0085] The above only describes some embodiments of the present application, and does not limit the protection scope of the present application, and any equivalent device or equivalent process transformation using the content of the specification and the drawings, or direct or indirect application in other related technical fields, are also included in the patent protection scope of the present application.
