Description

Technical Field

[0002] With the continuous development of intelligent sweeping robots, intelligent base stations equipped with charging, vacuuming and cleaning functions have become a development trend of intelligent sweeping robots. There are already quite a few intelligent base stations that integrate charging and vacuuming functions, but low vacuuming efficiency is a common disadvantage of such base stations.

[0003] The connection device at the connection between the dust collection pipe and the dust bag in the dust collection device not only affects the dust collection efficiency of the base station, but also directly affects the user experience. If the dust collection pipe and the dust bag are not tightly connected, local air leakage and dust leakage will occur, and the reduction in air tightness will further affect the dust collection efficiency of the base station; at the same time, if the connection between the dust collection pipe and the dust bag adopts a fixed connection or a more complicated connection, it will make the dust bag difficult to install and remove, resulting in a poor user experience. The interface between the existing dust collection pipe and the dust bag generally adopts a simple connection.

[0063] The specific implementation of the present application is described below in conjunction with the accompanying drawings.

[0064] In this document, “upper”, “lower”, “front”, “back”, “left”, “right”, etc. are only used to indicate the relative position relationship between related parts, rather than to limit the absolute positions of these related parts.

[0065] In this article, "first", "second", etc. are only used to distinguish each other, and do not indicate the importance and order, or the premise of each other's existence.

[0066] In this document, “equal”, “same”, etc. are not strictly limited in a mathematical and / or geometric sense, but also include errors that can be understood by those skilled in the art and are allowed in manufacturing or use.

[0067] Unless otherwise stated, the numerical ranges herein include not only the entire range within its two endpoints but also include several sub-ranges contained therein.

[0068] First, the robot involved in this application is schematically explained. The robot mentioned in this application can be various intelligent devices with cleaning functions, such as a sweeping robot with both sweeping and cleaning functions, a cleaning robot with only cleaning functions, etc. The cleaning task described in this application refers to the cleaning task performed on the driving wheels of the robot.

[0069] In the present application, the various shapes of the robot are not limited, such as ellipse, circle, convex polygon, etc., and the robot can implement the logic of the robot control method of the present application by installing software or APP in a controller used with the robot or writing a program in a corresponding device inside the robot.

[0070] Next, the structures of the dust collecting device and the robot cleaning base station involved in this embodiment are described in detail.

[0071] The present application provides a dust collecting device, such as Figures 1 to 3 As shown, it includes a connecting piece 1 and a dust collecting bucket 4, a dust outlet 12 is formed at one end of the connecting piece 1, the other end of the connecting piece 1 is connected to the dust collection pipe, and a dust bag and the connecting piece 1 are installed in the dust collecting bucket 4, wherein, when the dust collecting bucket 4 is in a dust collecting state, the dust bag needs to collect dust in the dust-laden airflow from the dust collection pipe through the connecting piece, and at this time, the dust outlet 12 extends into the dust bag; when the dust collecting bucket 4 is in a cleaning state, relative movement occurs between the dust bag and the dust collecting bucket 4, thereby triggering relative movement between the connecting piece 1 and the dust collecting bucket 4, so that the dust outlet 12 is detached from the dust bag.

[0072] The present application arranges a connector 1 between the dust suction duct and the dust bag, so that the connector 1 serves as a connecting structure between the dust suction duct and the dust bag, and extends into the dust bag through the dust outlet of the connector, thereby greatly improving the air tightness of the overall device and avoiding local air leakage and dust leakage.

[0073] In an embodiment of the present application, the dust collecting device also includes an opening mechanism, which is transmission-connected to the connecting member 1 and monitors the state of the dust bag through a travel switch or sensor arranged in the dust bucket 4. For example, when relative movement occurs between the dust bag and the dust bucket 4, the travel switch or sensor is triggered, and the opening mechanism drives the connecting member 1 to swing, so that the dust outlet 12 moves out of the dust bag, wherein the opening mechanism can be a connecting rod mechanism or a cam mechanism, etc. After the dust bag is taken out, the connecting member 1 is reset under the drive of the opening mechanism.

[0074] In the embodiments of the present application, Figure 1 and Figure 2 As shown, the dust collecting device also includes an elastic element 2, which is located on the side wall of the connecting member 1 and is arranged opposite to the opening direction of the dust outlet 12. When the dust bag is taken out, the connecting member 1 swings under the action of the dust bag, so that the dust outlet 12 moves out of the dust bag, and the elastic element 2 is compressed and deformed. After the dust bag is taken out, the connecting member 1 is reset under the action of the elastic element 2. At the same time, when there is an opening mechanism in the dust bucket 4, the opening mechanism can simultaneously realize the telescopic function under the action of the elastic element 2.

[0075] The dust outlet 12 extends into the dust bag under the action of the elastic element 2. When the dust bucket 4 is working, the dust-laden airflow passes through the multiple sections of the dust suction duct and enters the dust bag via the dust outlet 12 of the connecting piece 1, thereby realizing the dust collection function. When the dust bag is taken out from the dust bucket 4, the connecting piece 1 moves relative to the dust bag under the action of the dust bag, thereby being separated from the dust bag, and the connecting piece 1 is reset under the action of the elastic element 2, and restored to the original state in which the dust outlet 12 extends into the dust bag under the action of the elastic element 2.

[0076] The present application realizes the resetting function of the connector 1 through the elastic element 2, and has the advantages of being simple, practical and flexible in operation.

[0077] In the embodiments of the present application, Figure 1 and Figure 2 As shown, the dust collecting device also includes a rubber sleeve 3, one end of the rubber sleeve 3 is connected to the end of the connecting member 1 away from the dust outlet 12, and the other end of the rubber sleeve 3 is connected to the dust suction pipe, so that the dust suction pipe is connected to the connecting member 1.

[0078] The present application adopts a rubber sleeve 3 as a connecting transition structure between the dust collection duct and the connecting piece 1, which ensures the air tightness of the device while giving the device a certain degree of freedom, thereby facilitating the installation and removal of the dust bag.

[0079] In the embodiments of the present application, Figure 3 and Figure 4 As shown, the dust collecting bucket 4 includes a dust collecting chamber 41 for accommodating the dust collecting bag and an upper dust collecting chamber 42 for accommodating the connecting member 1, the dust collecting bag is arranged in the dust collecting chamber 41, and the upper dust collecting chamber 42 is arranged adjacent to the dust collecting chamber 41, and the elastic element 2 is abutted against the upper dust collecting chamber inner wall 45 of the upper dust collecting chamber 42, so that the connecting member 1 is tilted in the upper dust collecting chamber 42 under the action of elastic force, and the dust outlet 12 is located in the dust collecting chamber 41.

[0080] Compared with the existing dust collection duct dust bag connection method, the present application greatly reduces the risk of dust leakage and increases air tightness by extending the dust outlet 12 of the connecting member 1 into the dust bag.

[0081] In the above embodiment, the dust collecting bucket 4 also includes a dust bag fixing plate 43 and a dust bucket middle plate 44. The dust bag fixing plate 43 is arranged between the dust collecting chamber 41 and the upper dust bucket 42, so as to relatively seal and separate the dust collecting chamber 41 and the upper dust bucket 42. The dust outlet 12 passes through the dust bag fixing plate 43 and extends into the dust bag under the action of the elastic element 2. The dust bucket middle plate 44 is arranged at the bottom of the dust collecting chamber 41 and the upper dust bucket 42. One end of the rubber sleeve 3 is located in the upper dust bucket 42 and is connected to the connecting member 1. The other end of the rubber sleeve 3 passes through the dust bucket middle plate 44 and is connected to the dust suction duct.

[0082] In the above embodiment, the rubber sleeve 3 includes an annular reinforcing rib, which is arranged on the side wall of the rubber sleeve 3 at one end close to the dust bucket middle plate 44, and the annular reinforcing rib is limitedly cooperated with the annular limiting groove arranged on the dust bucket middle plate 44, so that the rubber sleeve 3 and the dust bucket middle plate 44 are limited and positioned through the bone position.

[0083] In the embodiments of the present application, Figure 5As shown, the connecting member 1 also includes a bone reinforcement rib 13 and a limiting boss 14. The bone reinforcement rib 13 is arranged on the side wall of the connecting member 1 close to one end of the rubber sleeve 3, and the bone reinforcement rib 13 cooperates with the bone limiting groove correspondingly arranged on the rubber sleeve 3. The limiting boss 14 is arranged on the side wall of the connecting member 1 close to one end of the rubber sleeve 3, and the limiting boss 14 cooperates with the limiting circular hole correspondingly arranged on the rubber sleeve 3, so as to prevent the connecting member 1 and the rubber sleeve 3 from falling off.

[0084] In the embodiments of the present application, Figure 2 and Figure 6 As shown, the connection between the elastic element 2 and the connecting member 1 is a fixed connection. The elastic element 2 is located on the side wall of the connecting member 1 on the side of the opening direction of the dust outlet 12. One end of the elastic element 2 is embedded in the connecting member 1, and the other end is against the inner wall 45 of the upper dust bucket. Specifically, the elastic element 2 includes a deformation end 21 and an embedding end 22. The deformation end 21 is located at the end of the elastic element 2 away from the connecting member 1 and is against the inner wall 45 of the upper dust bucket. The embedding end 22 is arranged in the embedding groove 15 located on the side wall of the connecting member 1. When the elastic element 2 is deformed under the action of the connecting member 1, the elastic element 2 is inclined so that the deformation end 21 is located below the embedding end 22. When the elastic element 2 is deformed, the embedding end 22 moves toward the deformation end 21.

[0085] In the embodiments of the present application, Figures 1 to 4 As shown, the connecting member 1 also includes a limiting arm 11, and relative movement occurs between the dust bag and the dust bucket 4, and the limiting arm 11 is arranged on the side wall of the connecting member 1 near the dust outlet 12 at one end; when the dust bucket 4 is in a cleaning state, due to the elasticity of the rubber sleeve 3, the limiting arm 11 interferes with the dust bag to drive the connecting member 1 to swing, so that the dust outlet 12 moves out of the dust bag, and at the same time, the elastic element 2 contacts and deforms with the inner wall 45 of the upper dust bucket. After the dust bag is taken out, the elastic element 2 resets and forces the connecting member 1 to return to its original position.

[0086] In the above embodiment, if Figures 7 to 9 As shown, the limiting arm 11 includes a protrusion 111, which is located on a side of the limiting arm 11 close to the dust outlet 12 and above the dust outlet 12, wherein the protrusion 111 has an angular protrusion, which is protruding along the opening direction of the dust outlet 12.

[0087] like Figure 7 and Figure 8As shown, when the dust bucket 4 is in the dust collecting state, the limiting arm 11 is abutted against the dust bag fixing plate 43 of the dust bucket 4 under the action of the elastic element 2, so that the protrusion 111 is located in the dust collecting cavity 41 of the dust bucket 4. That is, in order to ensure the smooth removal of the dust bag and the air tightness of the dust bucket 4 during operation, the present application has certain requirements on the protrusion 111 of the connecting member 1, the dust outlet 12 and its overall height. First, in order to meet the air tightness requirements during dust collection, the dust outlet 12 of the connecting member 1 must extend into the dust bag in the dust collecting state, and at the same time, it is necessary to ensure that the elastic element 2 is in contact with the inner wall 45 of the upper dust bucket, so that the connecting member 1 can abut against the dust bag fixing plate 43 without shaking.

[0088] like Figure 7 and Fig. 9 As shown, when the dust bucket 4 is in a cleaning state, the dust bag abuts against the protrusion 111 during the relative movement between the dust bucket 4, thereby driving the limiting arm 11 to move in a direction away from the dust collecting chamber 41 through the protrusion 111, and the limiting arm 11 drives the connecting member 1 as a whole to move in a direction away from the dust collecting chamber 41, that is, when the dust bag is extracted by pulling it out upward, the dust bag will press the protrusion 111, and the connecting member 1 will move in a direction away from the dust bag fixing plate 43, so that the dust bag can be smoothly extracted.

[0089] It should be noted that when the protrusion 111 moves to the vertical position where the dust bag fixing plate 43 of the dust collecting bucket 4 is located, the bottom end of the dust outlet 12 is flush with the protrusion 111 in the vertical direction, or the bottom end of the dust outlet 12 is located on the side of the protrusion 111 away from the dust bag fixing plate 43 in the vertical direction, that is, when the dust bag is taken out, the protrusion 111 of the connecting member 1 can be vertically consistent with the vertical direction of the bottom end of the dust outlet 12, or closer to the dust bag fixing plate 43, and the vertical position of the protrusion 111 cannot lag behind the vertical position of the bottom end of the dust outlet 12, otherwise the dust bag will be stuck in the dust outlet 12 when it is taken out.

[0090] Therefore, in order to avoid the dust bag being stuck in the dust outlet 12 when being taken out, the connector 1 should satisfy the following relationship:

[0091] like Figure 8As shown, assuming that the protrusion 111 is located at point A, the bottom end of the dust outlet 12 is located at point B, the theoretical rotation center point of the connecting member 1 is point O, assuming that the horizontal distance between point O and the vertical position of the dust bag fixing plate 43 is LO, the horizontal distance between point A and the dust bag fixing plate 43 is LA, and the straight-line distance between point O and point A is LOA, the rotation angle θ when the dust bag is taken out can be expressed by the following formula:

[0092] θ=arcos(LO / LOA)-arcos((LO+LA) / LOA);

[0093] Therefore, when designing the connecting member 1, it should be avoided that the rotation angle θ is too large to cause interference between the connecting member 1 and the inner wall of the upper dust bin, thereby making it difficult to remove the dust bag.

[0094] like Fig. 9 As shown, assuming that the horizontal distance between the protrusion 111 (i.e., point A) and the bottom end of the dust outlet 12 (i.e., point B) is L, and the vertical distance between the protrusion 111 (i.e., point A) and the bottom end of the dust outlet 12 (i.e., point B) is L1, the following relationship exists:

[0095] arctan(L / L1)>θ, that is, arctan(L / L1)>arcos(LO / LOA)-arcos((LO+LA) / LOA);

[0096] If the above relationship is not satisfied, when taking out the dust bag, when the protrusion 111 is pushed to the vertical position where the dust bag fixing plate 43 is located, the bottom end of the dust outlet 12 is not completely retracted to the side of the dust bag fixing plate 43 close to the upper dust bin inner wall 45, the dust bag will interfere with the dust outlet 12 when being pulled out, making it difficult to take out.

[0097] Optionally, the connecting member 1 includes two limiting arms 11, and the two limiting arms 11 are symmetrically arranged and extend to both sides of the dust outlet 12 to form a wing-shaped structure.

[0098] The present application also provides a robot cleaning base station, comprising: a base station body, on which a cleaning device and a dust collecting device are arranged, wherein the dust collecting device comprises a connecting piece 1, an elastic element 2 and a dust collecting bucket 4, a dust outlet 12 is formed at one end of the connecting piece 1, and the other end of the connecting piece 1 is connected to a dust suction pipe, the elastic element 2 is located on the side wall of the connecting piece 1 and is arranged opposite to the opening direction of the dust outlet 12, a dust collecting bag and the connecting piece 1 are installed in the dust collecting bucket 4, the dust outlet 12 extends into the dust collecting bag under the action of the elastic element 2, and when the dust collecting bag is taken out, the connecting piece 1 swings to be separated from the dust collecting bag, and is reset under the action of the elastic element 2.

[0099] Specific Example 1

[0100] At least one cleaning device and a dust collecting device are arranged on the base station body, and each cleaning device is docked with a sweeping robot respectively. The sweeping robot receives a return instruction during the execution of the cleaning task. In response to the return instruction, the sweeping robot receives a positioning signal sent by the base station body, and moves toward the cleaning device according to the positioning signal. After the cleaning device is docked with the sweeping robot, the cleaning device sucks out the dust in the sweeping robot and forms a dust-containing airflow. The dust-containing airflow passes through the multiple sections of the dust suction duct and enters the dust collecting bag via the dust outlet 12 of the connecting piece 1.

[0101] After cleaning, the sweeping robot leaves the base station body. When the user takes out the dust bag through the dust collection device, the dust bag triggers the travel switch or displacement sensor arranged in the dust bucket 4 during the movement, triggering the preset opening mechanism to act to make the connecting part 1 separate from the dust bag. After the dust bag is taken out, the opening mechanism is reset under the action of the elastic element 2, and at the same time drives the connecting part 1 to reset.

[0102] Specific Example 2

[0103] At least one cleaning device and a dust collecting device are arranged on the base station body, and each cleaning device is docked with a sweeping robot respectively. The sweeping robot receives a return instruction during the execution of the cleaning task. In response to the return instruction, the sweeping robot receives a positioning signal sent by the base station body, and moves toward the cleaning device according to the positioning signal. After the cleaning device is docked with the sweeping robot, the cleaning device sucks out the dust in the sweeping robot and forms a dust-containing airflow. The dust-containing airflow passes through the multiple sections of the dust suction duct and enters the dust collecting bag via the dust outlet 12 of the connecting piece 1.

[0104] After cleaning, the sweeping robot leaves the base station body. When the user takes out the dust bag through the dust collection device, the dust bag hits the protrusion 111 in the process of leaving the dust collecting chamber 41 of the dust bucket 4, thereby driving the limiting arm 11 to move away from the dust collecting chamber 41 through the protrusion 111, and the limiting arm 11 drives the connecting member 1 to move away from the dust collecting chamber 41 as a whole. After the dust bag is taken out, the connecting member 1 is reset under the action of the elastic element 2.
