[0023] Please refer to Figure 1 , Figure 1 The schematic diagram of the blade module 100 shown in an exemplary embodiment of the application.
[0024] The application provides a blade module 100 which can be applied to a base station of a sweeping machine, for cutting the debris collected by the sweeping machine, including but not limited to hair.
[0025] The blade module 100 includes a first blade 10 and a second blade 20, the first blade 10 includes a first surface 11 and a plurality of opening portions 12 arranged on the first surface 11, each of the opening portions 12 is formed on the first surface 11, and at least part of the edges of the first surface 11 is arranged as a first blade portion 121. Figure 1 In the embodiment shown, the first blade 10 adopts a flat plate structure, which is convenient for opening a large number of opening portions 12. The opening portion 12 can be of any shape, including but not limited to a circular opening portion, a square opening portion, and an oval opening portion.
[0026] The second blade 20 is movably connected to the first blade 10, and the second blade 20 is connected to the side of the first blade 10 where the plurality of opening portions 12 are arranged. The second blade 20 is provided with a second blade portion 21, which cooperates with the first surface 11 to cut the debris extending from the opening portion 12. The first blade portion 121 is arranged within the movement range of the second blade portion 21. During the movement of the second blade 20 relative to the first blade 10, the first blade portion 121 cooperates with the second blade portion 21 to cut.
[0027] In one embodiment, the second blade 21 can be in contact with the first surface 11, that is, the second blade 21 is always in contact with the first surface 11 during the movement of the second blade 20, and the shearing of the debris can be achieved when the first blade 121 intersects with the second blade 21, but not limited thereto. In other embodiments, the second blade 21 can also be in contact with the first surface 11, that is, a gap is reserved between the second blade 21 and the first surface 11, and the shearing of the debris can be achieved when the first blade 121 intersects with the second blade 21, and the specific contact mode can be set according to the type of debris. According to the above description, when the debris such as hair is cut by the blade module 100, especially when there is too much debris, the opening portion 12 can provide a partial accommodation space for the debris, so as to avoid too much debris being clamped between the first blade 121 and the second blade 21 at the same time, so that part of the debris outside the opening portion 12 can be cut off first during the cutting process, and then the debris inside the opening portion 12 is cut off in turn, thereby reducing the risk of the blade module 100 being stuck. The opening portion 12 can be provided as an integral type opening portion with a large opening area, or can be provided as a plurality of opening portions with a small opening area.
[0028] In one embodiment, the first blade 10 further comprises a second surface 13 facing away from the first surface 11, and the opening portion 12 penetrates the second surface 13. That is, the opening portion 12 penetrates the first blade 10, and the opening portion 12 can also be used as a debris discharge channel, so that the cut debris can also be discharged through the opening portion 12, further reducing the risk of the blade module 100 being stuck.
[0029] The specific way in which the second blade 20 is movably connected to the first blade 10 is not limited, for example, the two can be arranged to move relative to each other, or the two can rotate relative to each other, and in the present embodiment, the latter is adopted. That is, the second blade 20 is rotationally connected to the first blade 10. The rotational arrangement of the two can achieve uniform cutting, and the movement mode is simple and easy to implement.
[0030] In Figure 1In the illustrated embodiment, the first blade 10 has a connecting portion (not shown) rotatably connected to the second blade. Multiple openings 12 are provided, distributed on both sides of the connecting portion. Each opening 12 has at least a portion of its edge formed on the first surface 11, which is configured as a first cutting edge 121. The second blade 20 includes a mating portion (not shown) rotatably engaged with the connecting portion, and a first blade portion 201 and a second blade portion 202 connected to both sides of the mating portion. Both the first blade portion 201 and the second blade portion 202 are provided with the second cutting edge 21. This configuration allows for the corresponding increase of multiple first cutting edges 121 across the multiple openings 12. Furthermore, the first blade portion 201 and the second blade portion 202 can respectively engage with the first cutting edge 121 at different positions, improving cutting efficiency and increasing the cutting range, thereby increasing the amount of debris cut in a single operation. For example, when the second blade 20 rotates one revolution, the second cutting edge 21 of the first blade part 201 can cooperate with each first cutting edge 121 on both sides of the connecting part, and the second cutting edge 21 of the second blade part 202 can also cooperate with each first cutting edge 121 on both sides of the connecting part, thus enabling more cooperation positions to cut debris.
[0031] It should be noted that the location of the second blade 21 can be selected according to the direction of rotation of the second blade 20. In one embodiment, the second blade 20 can be set to rotate clockwise or counterclockwise, wherein the second blade 21 of the first blade 201 and the second blade 21 of the second blade 202 can be set according to the rotation direction of the second blade 20, for example, both are set on the side of each blade facing the debris.
[0032] exist Figure 1 In the embodiment shown, the second blade 20 rotates clockwise ( Figure 1 (As indicated by the arrow in the image), the second cutting edge 21 of the first blade portion 201 is disposed on the right edge near the first surface 11, and the second cutting edge 21 of the second blade portion 202 is disposed on the left edge near the first surface 11.
[0033] In some other embodiments, when the second blade 20 rotates counterclockwise ( Figure 1 When the direction of the arrow in the image is opposite, the second cutting edge 21 of the first blade portion 201 is provided on the left edge near the first surface 11, and the second cutting edge 21 of the second blade portion 202 is provided on the right edge near the first surface 11.
[0034] Of course, the second blade 20 can also be configured to rotate both clockwise and counterclockwise. In this case, a second cutting edge 21 can be provided on both sides of each blade part to accommodate the situation where the second blade 20 can rotate in both directions. In this case, the second cutting edge 21 of the first blade part 201 can be provided on the left and right edges near the first surface 11, and the second cutting edge 21 of the second blade part 202 can be provided on the left and right edges near the first surface 11.
[0035] In one embodiment, the plurality of openings 12 includes a plurality of first openings 12' on one side of the connecting portion and a plurality of second openings 12' on the other side of the connecting portion. At least one of the first openings 12' forms a plurality of edges with different extending directions on the first surface 11, and at least two edges with different extending directions are configured as first cutting edges 121. With this configuration, each first opening 12' has multiple edges that can be configured as first cutting edges 121, which increases the number of first cutting edges 121 in different positions, thereby increasing the probability of cutting debris and improving cutting efficiency.
[0036] In an alternative embodiment, each of the first openings 12' forms multiple edges on the first surface 11. For example, for a square-shaped first opening 12', four edges can be formed on the first surface 11, and all of these edges are configured as the first cutting edge 121. This can further increase the number of first cutting edges 121 and further improve cutting efficiency.
[0037] This application does not limit the second opening 12”. For example, the second opening 12” can be set in a manner similar to the first opening 12’, but is not limited thereto.
[0038] In one embodiment, the plurality of first openings 12' are configured as square openings with unequal opening areas. For example, a larger first opening 12' can be provided in a larger space on the first blade 10, and a smaller first opening 12' can be provided in a smaller space on the first blade 10, which is beneficial for making reasonable use of the space on the first blade 10. The shape of the second opening 12" can refer to the shape of the first opening 12', and will not be described in detail here.
[0039] exist Figure 1In the illustrated embodiment, the plurality of first opening portions 12' are arranged in multiple rows, each row having a plurality of first opening portions 12', and the first opening portions 12' in any two adjacent rows are arranged in staggered manner. That is, between any two adjacent first opening portions 12' in the same row, one of the first opening portions 12' in the row above or below can be arranged to face the position, so that the debris can be cut at multiple different positions, and the cut debris is more fragmented and is easier to be discharged or not to be easily stuck in the blade module 100. Figure 1 In the illustrated embodiment, the plurality of first opening portions 12' are arranged in three rows, and the first opening portions 12' in any two adjacent rows are arranged in staggered manner.
[0040] In one embodiment, the plurality of first opening portions 12' and the plurality of second opening portions 12" are symmetrically distributed on both sides of the connecting portion. In this way, the same cutting efficiency can be maintained at the first opening portions 12' and the plurality of second opening portions 12".
[0041] Please refer to Figure 2 and Figure 3 , Figure 2 is a schematic view of a partial structure of a robot base station. Figure 3 is another schematic view of a partial structure of a robot base station.
[0042] The present application provides a robot base station 200 comprising the blade module 100 described above. The robot base station 200 is used to supply water, charge, and clean debris for a robot. The blade module 100 is used to cut the debris such as hair on the roller brush of the robot.
[0043] In one embodiment, the blade module 100 is movably arranged, for example, repeatedly moves along a predetermined track, but is not limited thereto. The robot base station 200 is provided with an unfolded state for the robot to stop in, and when the robot stops in the robot base station 200, the roller brush faces the blade module 100. When the robot is in a water supply or charging state, the blade module 100 can be shielded by the baffle 210 to protect the blade module 100.
[0044] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the scope of protection of the present application.
