Embodiment one:

as shown in fig. 1 to 7, a cleaning device 100 according to a first embodiment of the present utility model includes a main cleaning belt member 10, where the main cleaning belt member 10 includes a first endless belt 11, a first roller 12, and at least one first guiding component 13, and the first endless belt 11 is rotatably wrapped around the first roller 12 and the first guiding component 13 for cleaning a surface 200 to be cleaned. The first roller 12 and the first guide member 13 may be used to support and tension the first endless belt 11 on the one hand so that the first endless belt 11 forms a predetermined endless structure, and on the other hand to guide the first endless belt 11 to rotate. In particular, when the first endless belt 11 is pressed against the surface to be cleaned 200 and rotated, the surface to be cleaned 200 can be cleaned and the garbage on the surface to be cleaned 200 can be conveyed to a predetermined position. In this embodiment, the cleaning surface 200 is cleaned by the first endless belt 11, so that the problem of secondary pollution caused by the winding of hair can be prevented, thereby improving the cleaning effect of the cleaning device 100.

It should be noted that the fact that the first endless belt 11 is rotatably wound around the first roller 12 and the first guide member 13 means that the first endless belt 11 is wound around not only the first roller 12 and the first guide member 13, but also the first endless belt 11 can be rotated with respect to the first roller 12 and the first guide member 13.

As an embodiment, the first rollers 12 and the at least one first guide member 13 are spaced apart in the height direction of the cleaning device 100, i.e., the first rollers 12 are disposed directly above or obliquely above or directly below or obliquely below the at least one first guide member 13. Specifically, the at least one first guide member 13 and the first roller 12 are disposed in a staggered manner along the height direction of the cleaning apparatus 100, that is, the height from the at least one first guide member 13 to the surface 200 to be cleaned is smaller or larger than the height from the first roller 12 to the surface 200 to be cleaned. In this embodiment, the first endless belt 11 may have a sufficiently large surface in the height direction, so that on one hand, the capability of the first endless belt 11 for conveying garbage can be improved, thereby facilitating the cleaning of garbage on the surface 200 to be cleaned under the driving of no wind force, and further facilitating the reduction of noise, power consumption and cost of the cleaning device 100; on the other hand, other functional components (such as a component for scraping garbage or a component for outputting cleaning liquid) are arranged in the height direction of the first annular belt 11 to treat the first annular belt 11, so that the first annular belt 11 can be ensured to have a good cleaning effect after continuously working.

As an embodiment, the surface 200 to be cleaned is a floor, i.e. the cleaning device 100 is used for cleaning floors. Of course, in specific applications, the surface 200 to be cleaned may also be a wall surface, a window, a ceiling, a glass surface, or other surfaces to be cleaned.

Specifically, the first roller 12 can freely rotate about its own center axis under the action of an external force. When the first roller 12 is driven to rotate by external force, the first annular belt 11 can be driven to rotate, so that the effects of cleaning the surface 200 to be cleaned and conveying garbage are achieved.

As an embodiment, the first roller 12 includes a rotating shaft 121, a bearing 122 and a roller body 123, the roller body 123 is rotatably mounted on the rotating shaft 121 through the bearing 122, and a part of the first endless belt 11 is wound around the roller body 123.

As an embodiment, the cleaning device 100 further includes a first motor 21, where the first motor 21 is in driving connection with the first roller 12, so as to drive the first roller 12 to rotate, thereby driving the first endless belt 11 to rotate. In this embodiment, the first roller 12 is driven to rotate by the first motor 21, which is simple in structure and easy to implement. Of course, in particular applications, the first roller 12 may be rotated by other power mechanisms or by manual force.

As an embodiment, the cleaning device 100 further includes a first transmission member 22, where the first transmission member 22 is drivingly connected between the first motor 21 and the first roller 12, and the first motor 21 drives the first roller 12 to rotate through the first transmission member 22. The disposing function of the first transmission member 22 may include at least one of the following functions: the rotation speed output by the first motor 21 is regulated to the rotation speed required by the design of the first roller 12; and the power transmission within a certain distance range is realized. The first transmission member 22 may include at least one of a belt transmission or a gear transmission or a chain transmission.

As one embodiment, the main cleaning belt member 10 may be maintained or replaced as a single module, which may be installed to the cleaning device 100 and removed from the cleaning device 100, thus allowing easy maintenance of the main cleaning belt member 10; alternatively, the main cleaning belt member 10 may be maintained or replaced as a separate module from the first motor 21 and mounted to the cleaning device 100 and removed from the cleaning device 100; alternatively, the main cleaning belt member 10 may not be designed as a separate module.

As an embodiment, the first motor 21 and the first transmission member 22 are both disposed outside the space enclosed by the first endless belt 11, and of course, in a specific application, at least part of the first motor 21 and the first transmission member 22 may be disposed inside the space enclosed by the first endless belt 11 as an alternative embodiment.

As an embodiment, the at least one first guiding member 13 is a roller, which can freely rotate around its central axis under the action of an external force, and the specific structure of the roller is referred to as the first roller 12, which is not described in detail herein. Here, the roller is adopted for the first guiding component 13, so that the first guiding component 13 can support, tension and guide the first annular belt 11, and is also beneficial to reducing the resistance of the first guiding component 13 to the first annular belt 11 in the rotating process of the first annular belt 11, thereby being beneficial to improving the smoothness of the rotation of the first annular belt 11. Of course, the arrangement of the first guide member 13 is not limited thereto, and for example, as an alternative embodiment, the first guide member 13 is a rod body having at least a partial outer surface of a cylindrical shape, and the first endless belt 11 is in contact with the cylindrical outer surface of the first guide member 13; alternatively, as another alternative embodiment, the first guide member 13 is a non-circular member having a partial outer surface with an arc shape, such as a plate member or a semi-cylinder or other irregularly shaped body having a partial outer surface with an arc shape, wherein the first endless belt 11 is in contact with the arc-shaped outer surface of the first guide member 13.

As an embodiment, the central axis of the first roller 12 and the central axis of each first guide member 13 are perpendicular to the height direction of the cleaning device 100, and the central axis of the first roller 12 and the central axis of each first guide member 13 are perpendicular to the moving direction of the cleaning device 100 when moving on the surface 200 to be cleaned.

As an embodiment, at least one first guide member 13 is provided for pressing a partial portion of the first endless belt 11 against the surface 200 to be cleaned. Of course, in a specific application, as an alternative embodiment, the first roller 12 may be used to press a partial portion of the first endless belt 11 against the surface 200 to be cleaned, and in this alternative embodiment, each first guiding member 13 is disposed directly above or obliquely above the first roller 12.

As an embodiment, the main cleaning belt member 10 comprises at least two first guiding means 13, each first guiding means 13 being a roller. Of course, in a specific application, as an alternative embodiment, each first guiding component 13 for pressing a local portion of the first annular belt 11 against the surface 200 to be cleaned may be a roller, and the remaining first guiding components 13 may be a rod body with at least a local outer surface having a cylindrical shape or a non-circular component with a local outer surface having an arc shape or other components without an arc-shaped outer surface.

As an embodiment, at least two first guiding components 13 are used for pressing a local part of the first annular belt 11 against the surface 200 to be cleaned, and by adopting the arrangement scheme, the bottom of the first annular belt 11 can form a second plane 111 pressed against the surface 200 to be cleaned, namely, the contact between the first annular belt 11 and the surface 200 to be cleaned is surface contact, so that the contact area between the first annular belt 11 and the surface 200 to be cleaned can be increased, and the cleaning effect and efficiency of the first annular belt 11 for cleaning the surface 200 to be cleaned can be improved; particularly, for the stubborn stains (such as coffee stains) on the surface 200 to be cleaned, the embodiment can quickly drag the stains to be cleaned, so as to achieve the aim of remarkably improving the cleaning effect and efficiency of the cleaning device 100 for cleaning the surface 200 to be cleaned.

As an embodiment, the first roller 12 and the at least one first guiding member 13 form the inclined surface 112 for conveying the garbage on the front side of the first endless belt 11, and this arrangement can advantageously prevent the garbage from falling down when the first endless belt 11 conveys the garbage. Of course, in a specific application, it is also possible that the front side of the first endless belt 11 is arranged vertically as an alternative embodiment.

As an embodiment, the outer diameters of the first guide members 13 for pressing the partial portions of the first endless belt 11 against the surface 200 to be cleaned are the same, and this arrangement is advantageous in reducing the amount of material in the cleaning apparatus 100 on the premise that the first endless belt 11 can be formed into the second plane 111. The outer diameter of the first guide member 13 specifically refers to the outer diameter of the circular arc outer surface of the first guide member 13 for cooperation with the first endless belt 11. Of course, in a specific application, as an alternative embodiment, a partial portion of the first annular belt 11 is pressed against each of the first guiding members 13 of the surface 200 to be cleaned, and there may be at least two first guiding members 13 having different outer diameters.

As an embodiment, the outer diameter of each first guide member 13 for pressing a partial portion of the first endless belt 11 against the surface 200 to be cleaned is smaller than the outer diameter of the first roller 12. Since the first roller 12 is a driving member for driving the first endless belt 11 to rotate, the load performance of the first roller 12 has a certain requirement, and thus the outer diameter of the first roller 12 cannot be designed to be too small. In this embodiment, on the premise of ensuring that the outer diameter of the first roller 12 meets the load requirement, the outer diameter of each first guiding component 13 for pressing the local part of the first annular belt 11 against the surface 200 to be cleaned is smaller than the outer diameter of the first roller 12, so that on one hand, the first annular belt 11 can be formed into a second plane 111 with a larger area by using the first guiding component 13 with a smaller volume, thereby being beneficial to reducing the size of the main cleaning belt component 10 in the moving direction (a certain horizontal direction) of the cleaning device 100 and reducing the cost of the first roller 12 on the premise of increasing the contact area between the first annular belt 11 and the surface 200 to be cleaned; on the other hand, the gap formed between the front bottom of the first annular belt 11 and the surface 200 to be cleaned is smaller, so that garbage can be prevented from entering the gap between the front bottom of the first annular belt 11 and the surface 200 to be cleaned. Of course, in a specific application, in an alternative embodiment, the outer diameter of at least the first guiding member 13 may be set to be equal to or larger than the outer diameter of the first roller 12 for pressing a partial portion of the first endless belt 11 against each of the first guiding members 13 of the surface to be cleaned 200.

As an embodiment, the first roller 12 is provided directly above or obliquely above the at least one first guide member 13 in the height direction of the cleaning device 100. At least part of the top of the first endless belt 11 is formed by the first roller 12.

As an embodiment, the first rollers 12 are provided directly above or obliquely above the respective first guide members 13 in the height direction of the cleaning device 100. The top of the first endless belt 11 is entirely formed by the first roller 12, the first roller 12 and each first guide means 13 can make the first endless belt 11 form a triangular endless structure, the first endless belt 11 forms an endless structure having three corners, two of which are located at the front bottom and rear bottom of the main cleaning belt member 10, respectively, and the other corner is located at the top of the main cleaning belt member 10. The outer contour of the first endless belt 11 resembles a triangle with rounded corners.

As an embodiment, the number of the first guide members 13 is two, and the first roller 12 and the two first guide members 13 respectively form three corners of the first endless belt 11.

As an embodiment, the cleaning apparatus 100 further includes a main frame 30 and a first link frame 41, and both the first roller 12 and the first guide member 13 are connected to the first link frame 41, and the first link frame 41 is mounted on the main frame 30. The first roller 12 is mounted on the first connecting frame 41 specifically through a rotation shaft 121. When the first guide member 13 is a roller, the first guide member 13 is connected to the first connecting frame 41 in a similar manner to the first roller 12; when the first guide member 13 is a rod body having at least a partial outer surface of a cylinder shape, an end of the rod body is rotatably or non-rotatably connected to the first connection frame 41; when the first guide member 13 is a non-circular member, the end of the first guide member 13 is fixedly connected to the first connection frame 41, that is, the first guide member 13 is not rotatable after the first guide member 13 is mounted on the first connection frame 41. In this embodiment, the first roller 12 and the first guide member 13 are both indirectly connected to the main frame 30 via the first connecting frame 41; of course, in a specific application, the first connecting frame 41 may not be provided as an alternative embodiment, so that the first roller 12 and the first guiding member 13 are directly connected to the main frame 30.

As an embodiment, both ends of the first roller 12 and both ends of the first guide member 13 are connected to the first connection frame 41. The two ends of the first roller 12 and the two ends of the first guide member 13, specifically, the two ends of the first roller 12 and the two ends of the first guide member 13, that is, the left and right ends of the first roller 12 and the left and right ends of the first guide member 13. In this embodiment, both ends of the first roller 12 and both ends of the first guide member 13 are connected to the first connecting frame 41, so that neither the first roller 12 nor the first guide member 13 is cantilever-type mounted, thereby facilitating the assurance of the stability of the mounting of the first roller 12 and the first guide member 13 and the assurance of the levelness of the first roller 12 and the first guide member 13, and further facilitating the assurance of the stability of the mounting of the main cleaning belt member 10.

As an embodiment, the first coupling frame 41 includes two plates 411 respectively located at both left and right sides of the main cleaning belt member 10, both ends of the first roller 12 are respectively connected to the two plates 411, and both ends of the first guide part 13 are respectively connected to the two plates 411.

As an embodiment, both the first roller 12 and the first guide member 13 are detachably connected to the first coupling frame 41, and with this arrangement, the maintenance or replacement of the main cleaning belt member 10 can be facilitated in a later stage.

As an embodiment, the first roller 12 is detachably connected to the first connecting frame 41 by a sliding snap connection, and the first guide member 13 is detachably connected to the first connecting frame 41 by a sliding snap connection. Specifically, the first roller 12 is slidably engaged with the first coupling frame 41 in the height direction of the cleaning device 100, and the first guide member 13 is slidably engaged with the first coupling frame 41 in the height direction of the cleaning device 100. With this arrangement, the main cleaning belt member 10 can be mounted and dismounted on the first connecting frame 41 in a sliding insertion and extraction manner as a whole as one module, so that the main cleaning belt member 10 can be mounted and dismounted on the first connecting frame 41 by hand by an operator, and the dismounting of the main cleaning belt member 10 becomes very easy. Since the first endless belt 11 is worn after long-term operation, it is necessary to remove and replace the first endless belt 11 periodically, in this embodiment, when the first endless belt 11 is required to be replaced, the entire main cleaning belt member 10 can be pulled out of the first connecting frame 41 by hand, the first endless belt 11 is removed and replaced, and the main cleaning belt member 10 is slid and clamped on the first connecting frame 41 after replacement. Of course, in specific applications, the connection manner of the first roller 12 and the first guide member 13 with the first connecting frame 41 is not limited thereto, and for example, as an alternative embodiment, the axial ends of the first roller 12 and the first guide member 13 may be locked and fixed by a screw or a pin or a clip spring, or, in the case that the first roller 12 and the first guide member 13 are detachably connected with the first connecting frame 41 by a sliding clip connection manner, at least one axial end of the first roller 12 and the first guide member 13 may be locked and fixed by a screw or a pin or a clip spring.

As an embodiment, the first connecting frame 41 is provided with a first latch (not shown) for limiting the first roller 12 and a second latch (not shown) for limiting the first guide member 13. The first elastic buckle is mainly used for limiting the displacement of the first roller 12 in the height direction of the cleaning device 100, and the second elastic buckle is mainly used for limiting the displacement of the first guide component 13 in the height direction of the cleaning device 100, so that the main cleaning belt component 10 can be inserted into and pulled out of the first connecting frame 41 under the action of external force on the premise of limiting the main cleaning belt component 10.

As an embodiment, the main cleaning belt member 10 further includes a supporting element 14, the supporting element 14 is disposed in a space formed by enclosing the first endless belt 11, and the supporting element 14 is connected to the first connecting frame 41. The provision of the support 14 may facilitate further strengthening of the stability of the connection of the main cleaning belt member 10 with the first connecting frame 41.

As an embodiment, the supporting member 14 is detachably connected to the first connecting frame 41 through a sliding card-inserting connection manner, and a third elastic buckle for limiting the supporting member 14 is arranged on the first connecting frame 41.

As an embodiment, the first connecting frame 41 is movably connected to the main frame 30, that is, after the first connecting frame 41 is connected to the main frame 30, the first connecting frame 41 can still be displaced relative to the main frame 30, when the main cleaning belt member 10 performs cleaning operation on the surface 200 to be cleaned, the main cleaning belt member 10 makes the main cleaning belt member 10 press against the surface 200 to be cleaned under the action of gravity of the main cleaning belt member 10 and the first connecting frame 41, so that the force acting on the surface 200 to be cleaned when the main cleaning belt member 10 cleans the surface 200 to be cleaned is increased, and the effect and efficiency of the main cleaning belt member 10 cleaning the surface 200 to be cleaned are improved.

As one embodiment, the cleaning device 100 further includes a pre-cleaning member 50, and the pre-cleaning member 50 is provided in front of the main cleaning belt member 10 in the moving direction of the cleaning device 100. The pre-cleaning member 50 is used to perform at least one of the following functions: the garbage on the surface to be cleaned 200 is guided to the main cleaning belt member 10, and the surface to be cleaned 200 is cleaned, and the garbage is transferred in cooperation with the main cleaning belt member 10.

It should be noted that, the moving direction may be understood as a forward direction of the cleaning device, for example, if the cleaning device needs to be pushed by a user, the moving direction may be understood as a corresponding direction when the user pushes the cleaning device forward; if the cleaning device is a self-moving device, the direction of movement is understood to be the direction of travel of the self-moving device, i.e. the main direction of travel when the cleaning device is cleaning a surface to be cleaned. Of course, the cleaning device may also back or turn in different situations, but in the embodiments of the present application, the moving direction of the cleaning device refers to the main running direction such as the advancing direction of the cleaning device, the advancing direction of the user, and so on.

In addition to the above differences, the cleaning device 100 according to the present embodiment may refer to the first, second, fourth, fifth and sixth embodiments, and will not be described in detail herein.

Example eight:

referring to fig. 1, 3, 6 and 14, the cleaning device 100 provided in this embodiment is different from the first embodiment mainly in the shaping manner of the first endless belt 11, and specifically includes: in the first embodiment, the first endless belt 11 is shaped by the first roller 12 and the first guide member 13; in this embodiment, the first endless belt 11 is shaped by the first roller 12, the first guide member 13 and the tension member.

Specifically, in the present embodiment, the main cleaning belt member 10 further includes a tensioning member that presses against the first endless belt 11 for tensioning the first endless belt 11. The tensioning part is arranged, so that the first annular belt 11 is always in a tensioning state, and the phenomenon that the first annular belt 11 influences the garbage conveying capacity due to looseness is avoided.

As an embodiment, the tensioning member is a third roller 15, and the third roller 15 can freely rotate around its central axis under the action of an external force, and the specific structure of the tensioning member may refer to the first roller 12, which is not described in detail herein. In this embodiment, the third roller 15 is used as the tensioning component, so that the tensioning component can tension and guide the first endless belt 11, and is further beneficial to reducing the resistance of the tensioning component to the first endless belt 11 in the process of rotating the first endless belt 11, thereby being beneficial to improving the smoothness of the rotation of the first endless belt 11.

As one embodiment, the tension member is provided outside the space enclosed by the first endless belt 11, and the tension member is positioned so that a recess is formed in a part of the first endless belt 11. In this embodiment, the tension member is provided on the outside of the first endless belt 11, and acts on the first endless belt 11 from the outside of the first endless belt 11, so that a part of the first endless belt 11 forms a recess that can be used to house other components of the cleaning device 100, thereby facilitating improvement in the structural compactness of the cleaning device 100.

As an embodiment, the first roller 12, the first guiding member 13 and the tensioning member are positioned such that the first endless belt 11 is L-shaped, thus facilitating both the formation of the second plane 111 at the bottom of the first endless belt 11 and the formation of a larger recess above the second plane 111 for receiving other components of the cleaning device 100.

In addition to the above differences, the cleaning device 100 according to the present embodiment may refer to the first, second and fourth to seventh embodiments, and will not be described in detail herein.

Example nine:

referring to fig. 1, 3, 14 and 15, the cleaning device 100 provided in this embodiment is different from the cleaning device 100 in the ninth embodiment mainly in the manner of setting the tensioning member, and specifically includes: in the eighth embodiment, the tension member is a member having a simple tension function; in the present embodiment, the tensioning member is a container in the cleaning device 100, and has a housing function in addition to the tensioning function.

Specifically, in the present embodiment, the tensioning member is a recovery container 73, and the recovery container 73 is used for recovering the refuse conveyed by the first endless belt 11 and for tensioning the first endless belt 11. Of course, in specific applications, the tensioning member may be other types of containers, such as a liquid storage container 72, where the liquid storage container 72 is used to store the liquid required for the operation of the cleaning device 100, i.e. to store the liquid required for the liquid outlet member 71 and to supply the liquid outlet member 71 with the liquid.

The tensioning member may be at least one of a rod body having a cylindrical shape at least in part and a non-circular member having an arc shape at least in part, that is, the third roller 17, the recovery container 73, the liquid storage container 72: the tensioning member is not limited to the third roller 17 or the recovery vessel 73 or the liquid storage vessel 72, but may be a rod body having at least a partial outer surface of a cylinder shape or a non-circular member having a partial outer surface of an arc shape; alternatively, the tension member may be at least two of a rod body having at least a partial outer surface of a cylinder shape and a non-circular member having a partial outer surface of an arc shape, including the third roller 17, the recovery vessel 73, the liquid storage vessel 72.

In addition to the above differences, the cleaning device 100 according to the present embodiment may refer to the first, second and fourth to eighth embodiments, and will not be described in detail herein.

In some embodiments, parameter settings are given for the relevant components and structures of the cleaning device 100. It should be noted that, the following embodiments provide a plurality of parameters, and the cleaning device may satisfy one parameter at a time, or may satisfy a plurality of parameters at the same time, which is not limited herein.

In some embodiments, as shown in fig. 16 and 17, the slope θ of the lead-in slope 54 may be set in order to clean various kinds of garbage to improve cleaning effect ₁ Greater than or equal to 10 degrees and less than or equal to 60 degrees. Wherein the gradient theta ₁ May also be referred to as the angle between the lead-in bevel 54 and the surface to be cleaned, i.e., the angle θ ₁ Greater than or equal to 10 degrees and less than or equal to 60 degrees. In other embodiments, the slope θ of the inclined lead-in surface may also be set ₁ 20 degrees or more and 40 degrees or less. In other embodiments, the slope of the inclined lead-in surface may also be set to be greater than or equal to 28 degreesLess than or equal to 32 degrees. Such a design may ensure that the cleaning device 100 more easily cleans the waste, i.e., may be understood as more easily "eating" the waste, thereby improving the cleaning effect.

In some embodiments, as shown in fig. 17, in order to clean various kinds of garbage, to enhance the cleaning effect of the cleaning device 100, the highest point of the introduction slope 54 may be set to be greater than or equal to 10mm and less than or equal to 100mm. The highest point of the lead-in slope 54 is in the range of 10mm-100mm, specifically, the distance d1 from the highest point of the lead-in slope 54 to the surface to be cleaned is in the range of 10mm-100 mm. The highest point may be a point corresponding to a maximum distance value from the leading-in inclined surface 54 to the surface to be cleaned, or may be a point corresponding to an intermediate distance value from the leading-in inclined surface 54 to the surface to be cleaned. Regardless of the point corresponding to the maximum distance value or the point corresponding to the intermediate distance value, the cleaning of the garbage with the corresponding size can be realized by selecting a proper value within the range of 10mm-100 mm.

Alternatively, the highest point of the lead-in chamfer 54 is open to the surface to be cleaned for the introduction of refuse, such as in some situations (e.g., outdoors) where there is some large fluctuation in refuse height, so that the highest point of the lead-in chamfer 54 is in the range of 10mm-100mm to accommodate refuse of different sizes.

In other embodiments, the highest point of lead-in chamfer 54 may be greater than or equal to 25mm and less than or equal to 40mm. Alternatively, since the larger garbage height of some scenes is generally below 40mm, the cleaning device can be facilitated to eat most of the garbage corresponding to the scene by setting the highest point of the leading-in slope to be greater than or equal to 25mm and less than or equal to 40mm.

And optionally, the leading-in inclined surface 54 and the surface to be cleaned integrally form a waste's leading-in port, in the above embodiment, by setting a proper gradient and the height of the highest point, the extending length of the whole leading-in inclined surface 54 is not too long to occupy space under the condition of meeting the height of the highest point, and the running length of the waste when being ' eaten ' too long can be optimized, thereby facilitating better waste eating.

In some embodiments, referring to fig. 17, and referring to fig. 18 and 19, a line L1 between portions of the two first guide members 13 near the surface to be cleaned may be provided in parallel with the surface to be cleaned. The connecting line L1 is parallel to the surface to be cleaned, so that the cleaning belt can be ensured to be completely attached to the surface to be cleaned, and the cleaning effect of the cleaning device can be improved.

It should be noted that, no matter whether the diameter sizes of the two first guiding members 13 are the same, the corresponding effect can be achieved by ensuring that the connecting line L1 between the portions of the two first guiding members 13 close to the surface to be cleaned is parallel to the surface to be cleaned. Illustratively, as shown in fig. 18, the diameters of the two first guide members 13 are the same, and a line L2 connecting the centers of the two first guide members 13 is parallel to the surface to be cleaned; as shown in fig. 19, the diameters of the two first guiding members 13 are different, and the connecting line L1 between the portions of the two first guiding members 13 near the surface to be cleaned is parallel to the surface to be cleaned, so that the surface to be cleaned can be completely attached to the surface to be cleaned, and the cleaning effect can be improved.

It should be further noted that, for convenience of description, please refer to fig. 16-20, the two first guide parts 13 in the main cleaning belt member 10 are respectively referred to as a guide part 122a and a guide part 122b, wherein the guide part 122a is one first guide part close to the pre-cleaning member 50, and the guide part 122b is the other first guide part far from the pre-cleaning member 50; and the two second guide parts 53 in the pre-cleaning means 50 are referred to as a guide part 222a and a guide part 222b, respectively, wherein the guide part 222a is one second guide part close to the main cleaning belt member 10 and the guide part 222b is the other second guide part far from the main cleaning belt member 10.

Also, as shown in fig. 17, 18 and 19, a portion of the second guide part 53 (guide part 222 a) close to the surface to be cleaned of the main cleaning belt member 10 may be provided on the same horizontal line as a portion of the first guide part 13 (guide parts 122a and 122 b) close to the surface to be cleaned of the main cleaning belt member 10. That is, it can be understood that the bottom connecting lines L1 of the guide members 222a, 122a and 122b are parallel to the surface to be cleaned. Therefore, the part of the guiding component and the part of the main cleaning belt component can be completely attached to the surface to be cleaned, so that the cleaning effect is improved, and the garbage conveying effect is also improved.

Further, the second guide part 53 (guide part 222 a) near the main cleaning belt member 10 has the same diameter as the first guide part 13, and the line connecting the second guide part 53 (guide part 222 a) near the main cleaning belt member 10 and the center of the first guide part 13 is parallel to the surface to be cleaned, as shown in fig. 18, specifically, the line L2 is parallel to the surface to be cleaned.

In some embodiments, as shown in fig. 18, an angle θ between the line L3 between the two second guide members 53 (the guide member 222a and the guide member 222 b) and the surface to be cleaned may be set in order to improve the adaptation of the cleaning apparatus to various kinds of garbage ₂ Greater than 0 ° and less than 90 °. Further, an angle θ of the line L3 between the two second guide members 53 (the guide member 222a and the guide member 222 b) and the surface to be cleaned may also be provided ₂ Greater than or equal to 20 deg., and less than or equal to 40 deg.. By corresponding the angle theta to the two second guiding components ₂ To further enhance the effect of the cleaning device in cleaning the garbage.

For example, the cleaning device may satisfy one parameter at the same time, or may satisfy a plurality of parameters at the same time. For example, the cleaning device satisfies that the line L1 of the guide member 222a, the guide member 122a and the guide member 122b is parallel to the surface to be cleaned, and the line L3 of the guide member 222a and the guide member 222a forms an angle θ with the surface to be cleaned ₂ 20 ° or more and 40 ° or less. Therefore, the cleaning device has better cleaning effect.

In some embodiments, in order to further improve the cleaning effect of the cleaning device, as shown in fig. 18, a distance d2 between the two first guide members 13 (i.e., the guide members 122a and 122 b) may be further provided to be greater than or equal to 0mm and less than or equal to 200mm. In other embodiments, the distance between two first guide members 13 may be greater than or equal to 30mm and less than or equal to 60mm. The larger the distance d2 between the two first guide members, the larger the effective area for mopping, but the larger the occupied space. However, in combination with the factors such as the structure and weight of the main belt cleaning member 10 provided in the embodiment of the present application, and the cooperation with the front cleaning member 50, the distance between the two first guiding components is set to be 0-200mm, especially 30-60mm, so that a better cleaning effect can be obtained.

In some embodiments, in order to improve the capacity of the main cleaning belt member 10 and the pre-cleaning member 50 to transfer the garbage and further improve the cleaning effect of the cleaning apparatus 100, as shown in fig. 16, a line between the first driving roller 121 and the first guiding part 13 (guiding part 122 b) far from the pre-cleaning member 50 may be further provided, and an angle θ between the surface to be cleaned ₃ Not equal to 90 deg..

In other embodiments, θ ₃ Or may be 90 deg..

In some embodiments, in order to obtain a superior effect in the size of the cleaning device and the garbage transfer capacity selection, as shown in fig. 16, a distance d3 between the first roller 12 and the first guide part 13 (guide part 122 b) distant from the pre-cleaning member 50 may be set to be greater than or equal to 0mm and less than or equal to 400mm. In other embodiments, a distance d3 between the first roller 12 and the first guide part 13 (guide part 122 b) remote from the pre-cleaning member 50 may also be provided, greater than or equal to 100mm and less than or equal to 200mm. The greater the distance d3 between the first roller 12 and the guide member 122b, the greater the height at which the refuse is transported, the greater the height at which the recycling container needs to be designed, but the greater the space taken up. The smaller the distance d3 between the first roller 12 and the guide member 122b, the lower the height at which the refuse is transported, the lower the height the recycling container needs to be designed, but the smaller the space taken up. Therefore, in combining these two factors, the distance d3 between the first roller 12 and the guide member 122b is limited to 0-400mm, alternatively, may be 100-200mm, so that the cleaning effect of the cleaning device is improved due to the improvement of the garbage conveying capability while the size requirement is satisfied.

In some embodiments, to increase the capacity of transporting the waste and thus the cleaning effect of the cleaning device, as shown in fig. 20, a first roller 12 and a first guide member 13 adjacent to the pre-cleaning member 50 may be further providedThe line L4 between the guide members 122 a) and the surface to be cleaned forms an angle θ ₄ Less than or equal to 90 °. Preferably, the line L4 between the first roller 12 and the first guide part 13 (guide part 122 a) close to the front cleaning member 50 and the angle theta between the surface to be cleaned can also be set ₄ Greater than or equal to 35 deg., and less than or equal to 55 deg.. The more vertical the angle guide 122a formed by the line between the first roller 12 and the guide 122a and the surface to be cleaned (angle θ ₄ Greater) the difficulty of garbage transportation is greater, whereas the difficulty of garbage transportation is smaller, so that an included angle theta is set ₄ In the corresponding range, the garbage conveying capacity can be improved, and the cleaning effect of the cleaning device is further improved. In some embodiments, in order to improve the ability of the cleaning device to accommodate various types of garbage while improving the cleaning effect, as shown in fig. 18 and 19, a distance d4 between the second guide part 53 (guide part 222 b) remote from the main cleaning belt member 10 and the surface to be cleaned may be greater than 0mm and less than or equal to 100mm. In order to better enhance the cleaning effect of the cleaning device, it is further possible to provide a distance d4 between the second guide part 53 (guide part 222 b) distant from the main cleaning belt member 10 and the surface to be cleaned of 25mm or more and 40mm or less.

In some embodiments, referring to fig. 16, a line between the second roller 52 and the second guide part (guide part 222 a) near the main cleaning belt member 10 may also be provided in parallel with a line between the first roller 12 and the first guide part 13 (guide part 122 a) near the pre-cleaning member 50. The line connecting the second roller 52 and the guide member 222a, which is parallel to the line connecting the first roller 12 and the guide member 122a, forms a plane for transporting the garbage, can provide a more uniform clamping force, thereby improving the garbage transporting effect and further improving the cleaning effect of the cleaning device.

In some embodiments, as shown in fig. 20, a distance d5 between the first roller 12 and the second roller 52 may also be provided that is greater than or equal to 20mm and less than or equal to 150mm. Further, the distance d5 between the first roller 12 and the second roller 52 may be set to be greater than or equal to 40mm and less than or equal to 80mm. Since the larger the distance between the first roller 12 and the second roller 52, the larger the space occupied, the smaller the distance between the two, the smaller the space occupied. Therefore, in combining these two factors, the first roller 12 and the second roller 52 are selected to be 40-80mm, so that a better effect can be achieved, and meanwhile, the fact that other structures and the whole structure of the cleaning device are larger due to the factors of the arrangement of the first roller 12 and the second roller 52 can be avoided, and further waste of space and cost is caused.

In some embodiments, in order to avoid depositing refuse between the pre-cleaning member 50 and the main cleaning belt member 10, thereby affecting the cleaning effect of the cleaning device, it is also possible to provide the diameter of the first guide part 13 (guide part 122 a) close to the pre-cleaning member 50 to be greater than or equal to 10mm and less than or equal to 40mm; and a diameter of the second guide part 53 (guide part 222 a) provided close to the main cleaning belt member 10 is greater than or equal to 10mm and less than or equal to 40mm.

Further, the diameter of the first guide part 13 (guide part 122 a) near the pre-cleaning member 50 may be set to 15mm or more and 25mm or less; and a diameter of the second guide part 53 (guide part 222 a) provided close to the main cleaning belt member 10 is 15mm or more and 25mm or less. By the design, the gap formed by the guide-in component and the main cleaning belt component is smaller, and the space for storing garbage is smaller, so that garbage accumulation can be avoided, and the cleaning effect is improved. It should be noted that the structural design of the lead-in member and the main cleaning belt member of the present application makes the cleaning device not lose effective cleaning area even though the diameter of the guide members 122a and 222a is set smaller than that of the conventional cleaning member design such as the drum design. Therefore, the optimized setting of the parameters can avoid garbage accumulation while the effective cleaning area is not lost, so that the cleaning effect is improved, and the cleaning efficiency is also improved.

In some embodiments, as shown in FIG. 16, a ratio of the distance d5 between the first roller 12 and the second roller 52 to the distance d6 between the first guide component 13 (guide component 122 a) proximate the pre-cleaning member 50 and the second guide component (guide component 222 a) proximate the main cleaning belt member 10 may also be set to be greater than or equal to 1, i.e., d5/d6+.1. In other embodiments, as shown in FIGS. 17 and 20, the ratio of the distance d5 between the first roller 12 and the second roller 52 to the distance d1 between the highest point of the lead-in chamfer 54 and the surface to be cleaned may be set to be greater than or equal to 0.8 and less than or equal to 1.4, i.e., 1.4. Gtoreq.d5/d1. Gtoreq.0.8. Alternatively, the garbage enters from between the highest point of the leading-in inclined surface 54 and the surface to be cleaned, and passes between the first roller 12 and the second roller 52, and the size of the garbage is not changed during the conveying process, so that the distance d5 between the first roller 12 and the second roller 52 corresponds to the distance d1 between the highest point of the leading-in inclined surface 54 and the surface to be cleaned, and the distance d5 may be slightly smaller than d1 considering that the garbage may be compressed during the conveying process. And optionally, the ratio of d5 to d1 is set to be 1.4 to be more than or equal to d5/d1 to be more than or equal to 0.8, so that one size is prevented from being relatively oversized, and the situation of excessive redundancy of one size is avoided.

In some embodiments, it is also possible to provide a ratio of the distance between the first roller 12 and the first guide part 13 (guide part 122 b) remote from the pre-cleaning means 50 to the distance of the two first guide parts 13 (guide part 122a and guide part 122 b) that is greater than 1 or less than 10. In other embodiments, it is also possible to provide a ratio of the distance between the second roller 52 and the second guide part 53 (guide part 222 a) adjacent to the main cleaning belt member 10 to the distance between the two second guide parts 53 (guide part 222a and guide part 222 b) of more than 1 or less than 10.

It should be noted that, the distance between two components in the above embodiment may be the distance from the center of one component to the center of the other component, or may be the distance from the center of the other component (such as an edge) to the center of the other component, or the distance from the center of one component to the other position of the other component (such as an edge), so long as the relative positions are taken to determine the distance.

The foregoing description of the preferred embodiments of the present utility model should not be construed as limiting the scope of the utility model, but rather should be understood to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the utility model as defined by the following description and drawings or any application directly or indirectly to other relevant art(s).
