[0030] The present invention solves the problem that cleaning equipment in the prior art is inconvenient to clean blind areas.

[0031] Example 1

[0032] This embodiment provides an auxiliary blind spot cleaning device for a cleaning device. The auxiliary blind spot cleaning device for a cleaning device is installed on the side of the transmission shaft of the cleaning device, such as Figures 1 to 3 As shown, the auxiliary blind spot cleaning device of the cleaning equipment includes a base 100, a driven component and a roller 700. The driven component is movably installed on the base 100, and the input end of the driven component is driven and connected to the transmission shaft; the output end of the driven component is driven and connected to the roller 700, and a cleaning part is provided on the roller 700.

[0033] Specifically, the cleaning device is installed on the side of the transmission shaft of the cleaning device and can rotate under the drive of the transmission shaft to clean the blind spot. The cleaning member is provided on the roller 700, and the transmission shaft drives the roller 700 to rotate through the driven component so that the cleaning member cleans the blind spot. During the rotation of the roller 700, the cleaning member contacts the garbage to be cleaned in the blind spot area and drives it to the front of the transmission shaft, so that the cleaned material enters the dust collection port of the cleaning device through the transmission shaft. The auxiliary blind spot cleaning device of the cleaning device effectively solves the problem that the current cleaning equipment is inconvenient to clean the blind spot.

[0034] Furthermore, the base 100 can be detachably mounted on the cleaning equipment to facilitate independent disassembly and assembly of the auxiliary blind spot cleaning device of the cleaning equipment. The base 100 can be mounted by snap-fitting or screw connection, depending on whether it can be detachable.

[0035] Furthermore, by setting a driven component, a preset transmission ratio can be achieved between the transmission shaft and the roller 700, and by replacing different driven components, different transmission ratios can be achieved between the transmission shaft and the roller 700. The specific transmission ratio can be set according to actual needs.

[0036] In this embodiment, the direction of the drum 700 can be changed by providing a driven component, that is, the rotation direction of the drum 700 can be opposite to the rotation direction of the transmission shaft through the driven component.

[0037] In this embodiment, the extending direction of the cleaning member is arranged toward a direction away from the input end, and the extending direction of the cleaning member forms a first angle with the axial direction of the transmission shaft.

[0038] Specifically, the inclined cleaning member can exert a force on the object to be cleaned when it rotates following the roller 700, so that the object to be cleaned moves toward the front area of the transmission shaft under the action of the cleaning member, that is, moves forward in the moving direction of the cleaning device. At this time, the rotation of the transmission shaft can bring the object to be cleaned into the dust collecting port of the cleaning device to achieve blind spot cleaning.

[0039] Furthermore, the first angle is greater than 0 degrees and less than 90 degrees. Of course, the specific angle can be adaptively set according to the specific size.

[0040] In this embodiment, a mounting hole 701 is provided on the drum 700 , at least a portion of the cleaning member is mounted inside the mounting hole 701 , and an extending direction of the mounting hole 701 forms a first angle with an axial direction of the drum 700 .

[0041] In this embodiment, the cleaning member is spaced apart from the base 100 to avoid the cleaning member from rubbing against the base 100 during rotation, thereby affecting the rotation efficiency of the cleaning member and further affecting the cleaning efficiency.

[0042] The cleaning member is provided on the outer peripheral surface of the drum 700 , and there may be one or more cleaning members. When there are multiple cleaning members, the cleaning members are spaced apart along the circumferential direction of the outer peripheral surface.

[0043] Specifically, a plurality of cleaning members are provided on the outer peripheral surface of the drum 700 so as to clean the objects to be cleaned in the blind area through the plurality of cleaning members, thereby enhancing the cleaning efficiency.

[0044] Of course, a cleaning member may be provided at the end of the drum 700 if necessary, specifically, the cleaning member can drive the object to be cleaned to the front area of the transmission shaft when the drum 700 drives the cleaning member to rotate.

[0045] In this embodiment, the transmission shaft is arranged parallel to the drum 700. Two different implementations are provided according to different installation positions of the drum 700, as follows.

[0046] like Figures 1 to 3 In the embodiment shown, the roller 700 is arranged coaxially with the transmission shaft.

[0047] Specifically, the input end of the driven component is drivingly connected to the transmission shaft, and both the input end and the output end of the driven component are coaxially arranged with the transmission shaft, so that the connection between the driven component and the transmission shaft is more stable and the transmission efficiency is enhanced.

[0048] In a specific embodiment not shown in the figures, the roller 700 and the transmission shaft are spaced apart along the forward direction of the cleaning device, and the axis of the roller 700 is located in front of the transmission shaft.

[0049] Specifically, the circumference of the drum 700 is located in front of the transmission shaft, so as to facilitate sweeping the objects to be cleaned in the blind area to the front of the transmission shaft, and avoid the phenomenon that the cleaning equipment moves too fast and the cleaning parts cannot completely drive the objects to be cleaned to the front of the transmission shaft.

[0050] like Figure 4 As shown, the base 100 has a mounting cavity 101, and the driven component includes an input shaft 200, an input transmission member, an output transmission member and an output shaft. The first end of the input shaft 200 is drive-connected to the transmission shaft, and the input transmission member is movably installed inside the mounting cavity 101. The second end of the input shaft 200 extends into the interior of the mounting cavity 101 and is drive-connected to the input transmission member. The output transmission member is movably installed inside the mounting cavity 101, and the output transmission member is rotationally connected to the input transmission member. One end of the output shaft is drive-connected to the output transmission member, and the other end of the output shaft extends to the outside of the mounting cavity 101 and is drive-connected to the roller 700.

[0051] Among them, the base 100 includes a first base 102, a second base 103 and a third base 104. The first base 102, the second base 103 and the third base 104 cooperate to form an installation cavity 101. The first base 102 is used to connect to the machine body. The second base 103 is an annular structure and one end is installed on the first base 102. The other end of the second base 103 is connected to the third base 104. The second end of the input shaft 200 passes through the first base 102 and extends into the interior of the installation cavity 101. The other end of the output shaft passes through the third base 104 and extends to the outside of the installation cavity 101 to be driven and connected to the roller 700.

[0052] Furthermore, the first base 102, the second base 103, and the third base 104 can be detachably connected or integrally connected. When the first base 102, the second base 103, and the third base 104 are detachably connected, the first base 102 and the third base 104 are connected via an axially arranged connecting member, and the second base 103 is limitedly disposed between the first base 102 and the third base 104.

[0053] Preferably, an annular opening is provided at one end of the third base portion 104 facing the second base portion 103 , and the end of the second base portion 103 away from the first base portion 102 abuts against or at least partially extends into the opening.

[0054] Of course, the first base 102 , the second base 103 and the third base 104 may also be connected in other ways, so long as they can achieve stable connection.

[0055] Specifically, the input transmission member includes a first external gear 300, and the output transmission member includes a second external gear 400 and an internal gear 600. The second external gear 400 is engaged with the first external gear 300, and the second external gear 400 is engaged with the internal gear 600. The end of the internal gear 600 away from the input shaft 200 is connected to the output shaft.

[0056] Furthermore, by having different numbers of teeth on the second external gear 400 and the internal gear 600, a transmission ratio is achieved between the second external gear 400 and the internal gear 600, and the transmission ratio can be adjusted by changing the numbers of teeth on the first external gear 300, the second external gear 400 and the internal gear 600.

[0057] It should be noted that the input shaft 200 drives the first external gear 300 to rotate in the same direction, and the first external gear 300 and the second external gear 400 are meshed to realize that the first external gear 300 drives the second external gear 400 to rotate. When the first external gear 300 and the second external gear 400 are meshed, the second external gear 400 and the first external gear 300 rotate in opposite directions. The second external gear 400 is meshed with the internal gear 600 to drive the internal gear 600 to rotate. At this time, the second external gear 400 and the internal gear 600 rotate in the same direction, and the first external gear 300 and the internal gear 600 rotate in opposite directions. The internal gear 600 drives the output shaft to rotate synchronously, and the output shaft drives the drum 700 to rotate, so that the drum 700 and the input shaft 200 rotate in opposite directions, that is, the transmission shaft and the drum 700 rotate in opposite directions.

[0058] like Figure 4 As shown, the driven assembly further includes a connecting shaft 500 , which is disposed inside the mounting cavity 101 and fixedly connected to the base 100 , and the second external gear 400 is rotatably disposed on the connecting shaft 500 .

[0059] Specifically, by setting a connecting shaft 500 on the base 100, the second external gear 400 is installed on the connecting shaft 500 and can rotate on the connecting shaft 500, so that the second external gear 400 can be rotatably installed inside the mounting cavity 101, ensuring the stable operation of the driven component.

[0060] Example 2

[0061] This embodiment is different from Example 1 in that the driven component in this embodiment only has the function of providing a transmission ratio between the transmission shaft and the drum 700 and does not have the function of changing direction, that is, the transmission shaft and the drum 700 have the same direction of rotation.

[0062] Specifically, the input transmission member includes a first external gear 300 , and the output transmission member includes an internal gear 600 . The first external gear 300 is drivingly connected to the internal gear 600 , and one end of the internal gear 600 away from the input shaft 200 is connected to the output shaft.

[0063] The first external gear 300 is meshed with the internal gear 600 to enable the first external gear 300 to drive the internal gear 600 to rotate, and the first external gear 300 and the internal gear 600 have different numbers of teeth, so as to achieve a transmission ratio between the first external gear 300 and the internal gear 600, and the first external gear 300 and the internal gear 600 are directly driven and connected, thereby ensuring that the input shaft 200 and the output shaft rotate in the same direction, thereby achieving the same direction rotation of the transmission shaft and the drum 700.

[0064] Example 3

[0065] The difference between this embodiment and Example 1 is that different transmission parts are used to achieve the transmission effect in this embodiment.

[0066] Specifically, the input transmission member includes a first pulley, the output transmission member includes a second pulley, the output shaft is arranged on the second pulley, and the driven component further includes a connecting belt.

[0067] The connecting belt between the first pulley and the second pulley is cross-arranged so that the first pulley and the second pulley rotate in opposite directions, thereby realizing reverse rotation of the input shaft 200 and the output shaft.

[0068] Example 4

[0069] The difference between this embodiment and embodiment 3 is that in this embodiment the input shaft 200 and the output shaft rotate in the same direction.

[0070] Specifically, the input transmission member includes a first pulley, the output transmission member includes a second pulley, the output shaft is arranged on the second pulley, and the driven component also includes a connecting belt, which is arranged in parallel between the first pulley and the second pulley so that the first pulley and the second pulley rotate in the same way.

[0071] Example 5

[0072] This embodiment provides a cleaning device. The cleaning device includes a body, a driving member, a transmission shaft, and the auxiliary blind spot cleaning device of the cleaning device in Example 1. The driving member is disposed on the body, the transmission shaft is disposed on the body and is rotatably connected to the driving member, the axis of the transmission shaft is disposed parallel to the cleaning surface, and the auxiliary blind spot cleaning device of the cleaning device is drivingly connected to the transmission shaft.

[0073] Specifically, during the process of cleaning the cleaning surface, the transmission shaft drives the auxiliary blind spot cleaning devices on both sides to clean the blind spots, wherein the axis of the transmission shaft and the axis of the roller 700 of the auxiliary blind spot cleaning device are both arranged parallel to the cleaning surface.

[0074] Furthermore, auxiliary blind spot cleaning devices of the cleaning equipment are respectively provided at both ends of the transmission shaft to facilitate comprehensive cleaning of the blind spots at both ends of the robot.

[0075] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0076] 1. The roller 700 and the cleaning member are provided to sweep the objects to be cleaned in the blind area to the front of the transmission shaft, thereby cleaning the blind area.

[0077] 2. By setting a driven component to achieve a transmission ratio between the drum 700 and the transmission shaft, the cleaning efficiency of the blind area can be improved.

[0078] Obviously, the embodiments described above are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, those skilled in the art may make other different forms of changes or modifications without making any creative work, and all of these should fall within the scope of protection of the present invention.
