The integrated baffle has a first guiding surface and a second guiding surface both facing the air inlet of the dust collection box. The first guiding surface extends from the air inlet to the air outlet of the dust collection box and gradually approaches one side wall of the dust collection box. The second guiding surface extends from the air inlet to the air outlet of the dust collection box and gradually approaches the other side wall of the dust collection box. The part of the dust collection baffle close to the bottom wall of the dust collection box can be deformed under the action of air flow. For the dust collection baffle, the dust collection assembly and the sweeping robot provided by the present invention, the air flow will flow to the side wall of the dust collection box under the guiding action of the first guiding surface and the second guiding surface to clean the "dead corners" of the dust collection box. The part of the dust collection baffle close to the bottom wall of the dust collection box can be deformed under the action of air flow. Therefore, during dust collection, the gap between the bottom wall of the dust collection baffle and the bottom wall of the dust collection box will increase, thereby preventing the air duct from being blocked.

Description

Technical Field

[0001] The present invention belongs to the technical field of smart home, and more specifically, relates to a dust collection baffle, a dust collection assembly and a floor cleaning robot. Background Art

[0002] Floor cleaning robots are increasingly widely used in daily life, greatly reducing the burden of cleaning. When the floor cleaning robot works, it sweeps dust into the dust collection box. After a certain cleaning time, the floor cleaning robot docks with the dust collection base station for dust collection. The larger the volume of the dust collection box, the longer the single working time can be, the higher the cleaning efficiency, and the invalid power consumption can be reduced to a certain extent. However, the larger the dust collection box, the actual effective volume does not increase with the increase of the theoretical volume, and "dead corners" are likely to appear at the internal corners, that is, the invalid volume, which brings inconvenience to dust collection and automatic ash dumping.

[0003] In order to eliminate the "dead corners", a wind guiding plate can be arranged inside the dust collection box so that when the dust collection station collects dust, the air flow can be guided to the "dead corners" of the dust collection box. However, after the wind guiding plate is arranged, larger garbage is easily stuck by the wind guiding plate, and in severe cases, the air duct is even blocked. Summary of the Invention

[0004] The purpose of the embodiments of the present invention is to provide a dust collection baffle, a dust collection assembly and a floor cleaning robot to solve the technical problem that the wind guiding plate in the prior art easily causes the air duct to be blocked.

[0005] To achieve the above purpose, the technical solution adopted by the present invention is: to provide a dust collection baffle for installation inside a dust collection box. The two sides of the dust collection baffle are respectively arranged at intervals with the two side walls of the dust collection box, and the bottom wall of the dust collection baffle is arranged at intervals with the bottom wall of the dust collection box. The dust collection baffle has a first guiding surface and a second guiding surface both facing the air inlet of the dust collection box. The first guiding surface extends from the air inlet to the air outlet of the dust collection box and gradually approaches one side wall of the dust collection box, and the second guiding surface extends from the air inlet to the air outlet of the dust collection box and gradually approaches the other side wall of the dust collection box. The part of the dust collection baffle close to the bottom wall of the dust collection box can be deformed under the action of air flow.

[0006] In one embodiment, the hardness of the dust collection baffle gradually decreases from its top to its bottom.

[0007] In one embodiment, the thickness of the dust collection baffle gradually decreases from its top to its bottom.

[0008] In one embodiment, the dust collection baffle includes a mounting portion and a deformable portion that can be deformed under the action of air flow. The deformable portion is connected to the lower side of the mounting portion, and the first guiding surface and the second guiding surface are both located on the deformable portion.

[0009] In one embodiment, the deformation part includes a plurality of comb teeth parts which are arranged at intervals in sequence and are all connected to the installation part.

[0010] In one embodiment, the deformation part is made of rubber and / or silica gel.

[0011] In one embodiment, the first guiding surface and the second guiding surface are flat surfaces or arc surfaces.

[0012] In one embodiment, the first guiding surface and the second guiding surface are both flat surfaces, and one side of the dust collection baffle facing the air inlet of the dust collection box is in a flared shape; or, the first guiding surface and the second guiding surface are arc surfaces, and one side of the dust collection baffle facing the air inlet of the dust collection box is in an arc shape.

[0013] In one embodiment, the parts of the dust collection baffle close to the two side walls of the dust collection box can be deformed under the action of air flow.

[0014] In one embodiment, the dust collection baffle includes a first baffle and a second baffle, the first guiding surface is located on the first baffle, and the second guiding surface is located on the second baffle.

[0015] In one embodiment, the parts of the first baffle and the second baffle far from the bottom wall of the dust collection box are connected to each other, and a notch is formed between the unconnected parts of the first baffle and the second baffle; or, the first baffle and the second baffle are integrally formed and arranged at intervals.

[0016] The present invention also provides a dust collection assembly, which includes the above-mentioned dust collection baffle and further includes a dust collection box, and the dust collection baffle is arranged in the dust collection box.

[0017] The present invention also provides a floor sweeping robot, which includes the above-mentioned dust collection assembly.

[0018] The beneficial effects of the dust collection baffle, the dust collection assembly and the floor sweeping robot provided by the present invention are as follows: Compared with the prior art, the dust collection baffle of the present invention has a first guiding surface and a second guiding surface. Since the first guiding surface and the second guiding surface both gradually extend towards the side wall of the dust collection box, when the dust collection assembly is cleaned by the dust collection station, the air flow will flow to the side wall of the dust collection box under the guiding action of the first guiding surface and the second guiding surface, so as to clean the "dead corner" of the dust collection box. The part of the dust collection baffle close to the bottom wall of the dust collection box can be deformed under the action of air flow. Therefore, during dust collection, the gap between the bottom wall of the dust collection baffle and the bottom wall of the dust collection box will increase, so that larger objects can enter the end of the dust collection box close to the air outlet from between the bottom wall of the dust collection baffle and the bottom wall of the dust collection box, thereby preventing the air duct from being blocked while cleaning the "dead corner" of the dust collection box.

[0037] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, "a plurality of" means two or more unless otherwise specifically defined.

[0038] Now, the dust collection baffle 1 provided by the embodiment of the present invention will be described. The dust collection baffle 1 is disposed in the dust collection box 2, and its function is to guide the airflow generated during dust collection to the inner wall of the dust collection box 2, clean the dust and garbage remaining on the inner wall and dead corners of the dust collection box 2, reduce the ineffective volume in the dust collection box 2, and make effective use of all the space in the dust collection box 2.

[0039] In one embodiment of the present invention, please refer to Figures 1 to 3 , Figure 1Cross-section when the dust collection component is not collecting dust Figure 1 and its cross-section is perpendicular to the air flow direction during dust collection Figure 2 Cross-section when the dust collection component is not collecting dust Figure 2 and its cross-section forms an acute angle with the air flow direction during dust collection Figure 3 Cross-section when the dust collection component is not collecting dust Figure 3 and its cross-section is parallel to the air flow direction during dust collection. The dust collection component includes a dust collection box 2 and a dust collection baffle 1. The dust collection baffle 1 is arranged inside the dust collection box 2 and functions to guide the air flow and clean the inner wall of the dust collection box 2

[0040] Please refer to Figures 1 to 3 , there is a dust collection cavity inside the dust collection box 2. During the long-term use of the dust collection box 2, dust is likely to deposit in dead corners such as the wall surface of the dust collection cavity and the corners of the dust collection cavity, which is not easy to clean. The longer the use time, the smaller the available space in the dust collection cavity will be. The dust collection box 2 has at least two side walls, a bottom wall, and a top wall. The two side walls are arranged opposite to each other and can be respectively named the first side wall 21 and the second side wall 22

[0041] When the dust collection baffle 1 is installed inside the dust collection box 2, there is a gap between one side wall of the dust collection baffle 1 and the first side wall 21 of the dust collection box 2, and there is a gap between the other side wall of the dust collection baffle 1 and the second side wall 22 of the dust collection box 2. There is a gap between the bottom wall of the dust collection baffle 1 and the bottom wall of the dust collection box 2. The channel formed by the above gaps is the air flow channel. When the dust collection component is collecting dust in the dust collection station 4, the air flow generated by dust collection enters the dust collection cavity through the air inlet 201 of the dust collection box 2, and then under the guidance of the dust collection baffle 1, gradually flows to the air outlet 202 of the dust collection box 2 through the air flow channel

[0042] Please refer to Figure 4 , the dust collection baffle 1 has a first guiding surface 101 and a second guiding surface 102. The first guiding surface 101 is used to guide the air flow to the first side wall 21, and the accumulated dust on the first side wall 21 is blown off by the air flow through the first guiding surface 101. The second guiding surface 102 is used to guide the air flow to the second side wall 22, and the accumulated dust on the second side wall 22 is blown off by the air flow through the second guiding surface 102. More specifically, the first guiding surface 101 gradually extends from the air inlet 201 of the dust collection box 2 to the air outlet 202 of the dust collection box 2 and gradually approaches the first side wall 21, so that the air flow also gradually approaches the first side wall 21 from the air inlet 201 of the dust collection box 2 to the air outlet 202 of the dust collection box 2, thereby blowing off the accumulated dust on the first side wall 21; the second guiding surface 102 gradually extends from the air inlet 201 of the dust collection box 2 to the air outlet 202 of the dust collection box 2 and gradually approaches the second side wall 22, so that the air flow also gradually approaches the second side wall 22 from the air inlet 201 of the dust collection box 2 to the air outlet 202 of the dust collection box 2, thereby blowing off the accumulated dust on the second side wall 22

[0043] Please refer to Figures 5 to 8 , the part of the dust collection baffle 1 close to the bottom wall of the dust collection box 2 can be deformed under the action of air flow. That is to say, the lower side of the dust collection baffle 1 can be deformed under the action of air flow. In this way, when the dust collection station 4 is collecting dust, the bottom of the dust collection baffle 1 will bend towards the air outlet 202 of the dust collection box 2, increasing the distance between the bottom wall of the dust collection baffle 1 and the bottom wall of the dust collection box 2, so that larger garbage can pass through from the bottom wall of the dust collection box 2, preventing the garbage from getting stuck in the air flow channel. Moreover, larger garbage generally has a greater weight. Therefore, most of the large-volume garbage will be located at the bottom wall of the dust collection box 2 during dust collection. When the dust collection baffle 1 is deformed, the large-volume garbage can smoothly pass through the air flow channel from the bottom wall of the dust collection box 2.

[0044] The dust collection baffle 1 in the above-mentioned embodiment has a first guiding surface 101 and a second guiding surface 102. Since both the first guiding surface 101 and the second guiding surface 102 gradually extend towards the side wall of the dust collection box 2, during dust collection, the air flow will flow to the side wall of the dust collection box 2 under the guiding action of the first guiding surface 101 and the second guiding surface 102, cleaning the "dead corners" of the dust collection box 2. The part of the dust collection baffle 1 close to the bottom wall of the dust collection box 2 can be deformed under the action of air flow. Therefore, during dust collection, the gap between the bottom wall of the dust collection baffle 1 and the bottom wall of the dust collection box 2 will increase, enabling larger objects to enter the end of the dust collection box 2 close to the air outlet 202 from between the bottom wall of the dust collection baffle 1 and the bottom wall of the dust collection box 2, so as to prevent the air duct from being blocked while cleaning the "dead corners" of the dust collection box 2.

[0045] Optionally, there may also be a gap between the top wall of the dust collection baffle 1 and the top wall of the dust collection box 2, and the space formed by this gap is also a part of the air flow channel.

[0046] In one embodiment of the present invention, the hardness of the dust collection baffle 1 gradually decreases from the top of the dust collection baffle 1 to the bottom of the dust collection baffle 1. That is to say, the closer the dust collection baffle 1 is to the bottom wall of the dust collection box 2, the softer it is. In this way, during dust collection, since the hardness of the bottom of the dust collection baffle 1 is relatively soft, under the impact of the dust collection air flow, the bottom of the dust collection baffle 1 will tilt towards the air outlet 202 of the dust collection box 2, enabling large-volume garbage to pass through.

[0047] In one embodiment, the material used for the dust collection baffle 1 in each part is the same, and by making the thickness of the dust collection baffle 1 gradually decrease from its top to its bottom, the hardness of the dust collection baffle 1 is gradually reduced from its top to its bottom.

[0048] In another embodiment, the material components of the dust collection baffle 1 are different at each of its parts. For example, more hard components are added to the top of the dust collection baffle 1, and fewer hard components are added to the bottom of the dust collection baffle 1. The more hard components the dust collection baffle 1 contains, the higher its hardness. The hard components can be fibers, nano glass powder, etc.

[0049] In one embodiment of the present invention, the thickness of the dust collection baffle 1 gradually decreases from the top of the dust collection baffle 1 to the bottom of the dust collection baffle 1. That is to say, the closer the dust collection baffle 1 is to the bottom wall of the dust collection box 2, the thinner its thickness. Due to the change in the thickness of the dust collection baffle 1, the closer the dust collection baffle 1 is to the bottom wall of the dust collection box 2, the softer it is and can deform during dust collection.

[0050] In one embodiment, the materials of each part of the dust collection baffle 1 can be the same, such as silicone material, rubber material, etc.

[0051] In another embodiment, a soft component can be added to the dust collection baffle 1 near the bottom wall of the dust collection box 2 to make the dust collection baffle 1 softer and more easily deformable near the bottom wall of the dust collection box 2. The soft component can be a plasticizer.

[0052] In one embodiment of the present invention, please refer to Figure 4 , the dust collection baffle 1 includes a mounting portion 11 and a deformation portion 12. The deformation portion 12 is connected to the lower side of the mounting portion 11. The deformation portion 12 can deform under the action of the airflow during dust collection, so that larger garbage can pass between the deformation portion 12 and the bottom wall of the dust collection box 2. Among them, the first guiding surface 101 and the second guiding surface 102 are both located on the side of the deformation portion 12 facing the air inlet of the dust collection box 2 to guide the airflow.

[0053] Optionally, the mounting portion 11 is made of a hard material and will not deform under the action of the airflow. In this way, the deformation amount of the entire dust collection baffle 1 can gradually decrease from its bottom to its top, and the entire dust collection baffle 1 will not be lifted, ensuring that part of the airflow is still guided by the first guiding surface 101 and the second guiding surface 102 to the side wall of the dust collection box 2.

[0054] Among them, the mounting portion 11 can be connected to the top wall of the dust collection box 2, such as being detachably mounted on the top wall of the dust collection box 2 by means of screw connection, snap connection, etc., which is convenient for installation after the dust collection baffle 1 and the dust collection box 2 are integrally formed.

[0055] In one embodiment, the mounting portion 11 is integrally formed with the dust collection box 2, and after the dust collection box 2 is processed, the deformation portion 12 is then mounted on the mounting portion 11.

[0056] In another embodiment of the present invention, the dust collection baffle 1 only includes the deformation portion 12, and the deformation portion 12 is directly mounted on the top wall of the dust collection box 2.

[0057] In one embodiment of the present invention, please refer to Figure 4 and Figure 8 , the deformation part 12 includes a plurality of comb teeth parts 121 arranged at intervals in sequence, making the dust collection baffle 1 similar to the shape of a comb. Since the deformation part 12 is composed of a plurality of comb teeth parts 121, it can also be deformed under the action of air flow.

[0058] In one embodiment, the deformation part 12 is installed on the installation part 11, and a plurality of comb teeth parts 121 are all connected to the installation part 11. The length direction of the comb teeth part 121 can be the vertical direction. In this embodiment, each comb teeth part 121 is cantilevered. One end of the comb teeth part 121 is fixed to the installation part 11, and the other end of the comb teeth part 121 is far from the installation part 11, so it is easy to be deformed by force.

[0059] In another embodiment, the deformation part 12 is directly installed on the top wall of the dust collection box 2, and a plurality of comb teeth parts 121 are all connected to the top wall of the dust collection box 2. The plurality of comb teeth parts 121 are arranged at intervals in sequence from the first side wall 21 to the second side wall 22 of the dust collection box 2. The length direction of the comb teeth part 121 can be the vertical direction. In this embodiment, each comb teeth part 121 is also cantilevered. One end of the comb teeth part 121 is fixed to the top wall of the dust collection box 2, and the other end of the comb teeth part 121 is far from the top wall of the dust collection box 2, so it is easy to be deformed by force.

[0060] In one embodiment of the present invention, the deformation part 12 is made of materials such as rubber, silica gel, and a mixture of rubber and silica gel, and can also make the deformation part 12 deform under the action of air flow. The upper end of the deformation part 12 is fixed by the installation part 11 or the top wall of the dust collection box 2, which can prevent the deformation amount of the deformation part 12 from being too large, resulting in an overly large air flow channel on the lower side of the deformation part 12, and further ensuring that the air flow can be guided towards the first side wall 21 and the second side wall 22 of the dust collection box 2.

[0061] Optionally, the hardness of the deformation part 12 gradually decreases from its top to its bottom, making the bottom of the deformation part 12 easier to deform.

[0062] Optionally, the thickness of the deformation part 12 gradually decreases from its top to its bottom, making the bottom of the deformation part 12 easier to deform.

[0063] In one embodiment of the present invention, when the dust collection baffle 1 is not deformed, the distance between the bottom wall of the dust collection baffle 1 and the bottom wall of the dust collection box 2 is greater than or equal to 2 mm, so that there is enough space between the bottom wall of the dust collection baffle 1 and the bottom wall of the dust collection box 2 for larger garbage to pass through.

[0064] In one embodiment of the present invention, the portions of the dust collection baffle 1 close to the first side wall 21 and the second side wall 22 of the dust collection box 2 can be deformed under the action of air flow. In this way, even when relatively large garbage is located on the side of the dust collection baffle 1, it can pass through between the side wall of the dust collection baffle 1 and the side wall of the dust collection box 2.

[0065] Optionally, both sides of the dust collection baffle 1 are made of soft materials, such as silicone, rubber, etc.

[0066] Optionally, the thickness of the dust collection baffle 1 gradually decreases from the center to both sides, so that both sides of the dust collection baffle 1 can be deformed under the action of air flow.

[0067] Optionally, a plurality of comb-shaped portions are arranged at intervals on both sides of the dust collection baffle 1. The comb-shaped portions are strip-shaped. When the floor sweeping robot 3 is placed normally, the length direction of the comb-shaped portions can be the horizontal direction or close to the horizontal direction. In this way, both sides of the dust collection baffle 1 can also be deformed under the action of air flow, so that the garbage can pass through between the side wall of the dust collection baffle 1 and the side wall of the dust collection box 2.

[0068] In one embodiment of the present invention, please refer to Figure 1 and Figure 4 , one side of the first guiding surface 101 is close to the center of the dust collection box 2, and the other side of the first guiding surface 101 is close to the first side wall 21 of the dust collection box 2. Moreover, the side of the first guiding surface 101 located at the center of the dust collection box 2 is closer to the air inlet 201 of the dust collection box 2. One side of the second guiding surface 102 is located at the center of the dust collection box 2, and the other side of the second guiding surface 102 is close to the second side wall 22 of the dust collection box 2. Moreover, the side of the second guiding surface 102 located at the center of the dust collection box 2 is closer to the air inlet 201 of the dust collection box 2.

[0069] In one embodiment, please refer to Figure 4 , both the first guiding surface 101 and the second guiding surface 102 are flat surfaces. After the air flow reaches the dust collection baffle 1, under the guidance of the dust collection baffle 1, it is respectively diverted to the left and right sides and flows along the first guiding surface 101 and the second guiding surface 102. The air flow direction is an inclined direction (inclined relative to the air flow direction at the air inlet 201).

[0070] Optionally, both the first guiding surface 101 and the second guiding surface 102 are flat surfaces, so that the side of the dust collection baffle 1 facing the air inlet 201 of the dust collection box 2 is in a flared shape, so that the air flow can be more quickly respectively guided to the first side wall 21 and the second side wall 22 of the dust collection box 2.

[0071] In another embodiment, both the first guiding surface 101 and the second guiding surface 102 are arc surfaces. After the air flow reaches the dust collection baffle 1, under the guidance of the dust collection baffle 1, it is respectively shunted to the left and right sides and flows along the first guiding surface 101 and the second guiding surface 102, and the air flow direction is the arc direction.

[0072] Optionally, both the first guiding surface 101 and the second guiding surface 102 are arc surfaces, and the centers and radii of the first guiding surface 101 and the second guiding surface 102 are the same. In this way, the first guiding surface 101 and the second guiding surface 102 can form a complete arc surface, which is more convenient for the processing of the dust collection baffle 1. The corresponding central angle of this arc surface can be between 90 degrees and 180 degrees. The first guiding surface 101 and the second guiding surface 102 can also be circular arcs with different radii, and the connection between the first guiding surface 101 and the second guiding surface 102 can be set to be tangent to prevent the generation of turbulent air flow at the connection of the first guiding surface 101 and the second guiding surface 102.

[0073] In yet another embodiment, the first guiding surface 101 is a plane and the second guiding surface 102 is an arc surface. After the air flow reaches the dust collection baffle 1, under the guidance of the dust collection baffle 1, it is respectively shunted to the left and right sides and flows along the first guiding surface 101 and the second guiding surface 102. The air flow direction along the first guiding surface 101 is an inclined direction (inclined relative to the air flow direction at the air inlet 201), and the air flow direction along the second guiding surface 102 is an arc direction. Or, the first guiding surface 101 is an arc surface and the second guiding surface 102 is a plane.

[0074] In one embodiment of the present invention, please refer to Figure 4 , the dust collection baffle 1 includes a first baffle 14 and a second baffle 15. The first guiding surface 101 is located on the first baffle 14, and the second guiding surface 102 is located on the second baffle 15. Both the first baffle 14 and the second baffle 15 can be deformed under the action of the air flow. Since the deformation directions of the first baffle 14 and the second baffle 15 are the same, the connection parts of the first baffle 14 and the second baffle 15 are deformed towards the end of the air outlet 202 of the dust collection box 2, which may cause interference between the connection parts of the first baffle 14 and the second baffle 15 during dust collection deformation. To prevent interference between the first baffle 14 and the second baffle 15, an avoidance opening can be provided at the connection of the first baffle 14 and the second baffle 15 so that the first baffle 14 and the second baffle 15 can deform freely.

[0075] Optionally, the first baffle 14 and the second baffle 15 are integrally formed and are respectively installed on the top wall of the dust collection box 2, and the first baffle 14 and the second baffle 15 are arranged at intervals, and the space formed by the intervals is the above-mentioned avoidance opening.

[0076] Optionally, please refer to Figure 4, the first baffle 14 and the second baffle 15 are integrally formed, and the first baffle 14 and the second baffle 15 are connected at one end away from the bottom wall of the dust collection box 2. In this way, a notch 16 is formed between the first baffle 14 and the second baffle 15, and this notch 16 is the above-mentioned avoidance opening.

[0077] In one embodiment of the present invention, please refer to Figure 1 and Figure 2 , both the first baffle 14 and the second baffle 15 include comb teeth portions 121, and the comb teeth portions 121 on the first baffle 14 and the second baffle 15 together form a deformation portion 12, so that the lower sides of the first baffle 14 and the second baffle 15 can be deformed under the action of air flow.

[0078] In another embodiment of the present invention, please refer to Figure 9 and Figure 10 , the first baffle 14 and the second baffle 15 are in the form of a complete plate. By setting the lower sides of the first baffle 14 and the second baffle 15 as soft materials, the lower sides of the first baffle 14 and the second baffle 15 can also be deformed under the action of air flow.

[0079] In one embodiment of the present invention, please refer to Figure 4 , the dust collection baffle 1 further includes a mounting top plate 13. The first baffle 14 and the second baffle 15 are both connected to the lower side of the mounting top plate 13, and the mounting top plate 13 is used to be fixed on the top wall of the dust collection box 2. The mounting top plate 13 can be perpendicularly arranged with the first baffle 14 and the second baffle 15, making it easier to install the dust collection baffle 1.

[0080] Please refer to Figure 11 , the present invention also provides a dust collection assembly. The dust collection assembly includes the dust collection baffle 1 in any of the above embodiments. The dust collection assembly further includes a dust collection box 2. The dust collection box 2 has an air inlet 201 and an air outlet 202. The dust collection baffle 1 is arranged inside the dust collection box 2. There is a gap between one side wall of the dust collection baffle 1 and the first side wall 21 of the dust collection box 2, and there is a gap between the other side wall of the dust collection baffle 1 and the second side wall 22 of the dust collection box 2. There is a gap between the bottom wall of the dust collection baffle 1 and the bottom wall of the dust collection box 2. The channel formed by the above gaps is the air flow channel. When the dust collection assembly is collecting dust in the dust collection station 4, the air flow generated by dust collection enters the dust collection cavity through the air inlet 201 of the dust collection box 2, and then under the guidance of the dust collection baffle 1, gradually flows to the air outlet 202 of the dust collection box 2 through the air flow channel.

[0081] Among them, the dust collection baffle 1 is fixedly connected or detachably connected to the dust collection box 2.

[0082] The dust collection component provided by the present invention, the dust collection baffle 1 thereof has a first guiding surface 101 and a second guiding surface 102. Since both the first guiding surface 101 and the second guiding surface 102 gradually extend towards the side wall of the dust collection box 2, during dust collection, the air flow will flow to the side wall of the dust collection box 2 under the guiding action of the first guiding surface 101 and the second guiding surface 102, so as to clean the "dead corners" of the dust collection box 2. The bottom of the dust collection baffle 1 near the bottom wall of the dust collection box 2 can be deformed under the action of the air flow. Therefore, during dust collection, the gap between the bottom wall of the dust collection baffle 1 and the bottom wall of the dust collection box 2 will increase, so that larger objects can enter from between the bottom wall of the dust collection baffle 1 and the bottom wall of the dust collection box 2 to the end of the dust collection box 2 near the air outlet 202, thereby preventing the air duct from being blocked while cleaning the "dead corners" of the dust collection box 2.

[0083] Please refer to Figure 12 , the present invention also provides a floor cleaning robot 3. The floor cleaning robot 3 includes the dust collection component in any of the above embodiments. The dust collection component can be arranged at the bottom of the floor cleaning robot 3, that is, the dust collection box 2 is arranged at the bottom of the floor cleaning robot 3. The dust collection box 2 can be detachably connected to the main body of the floor cleaning robot, which is convenient for disassembling the dust collection component for cleaning. The dust collection station 4 includes an air circuit system, which can suck air and suck the garbage and dust collected in the dust collection box 2 into the interior of the dust collection station 4. The air inlet 201 of the air circuit system is communicated with the air outlet 202 of the dust collection box 2.

[0084] For the floor cleaning robot 3 provided by the present invention, the dust collection baffle 1 of its dust collection component has a first guiding surface 101 and a second guiding surface 102. Since both the first guiding surface 101 and the second guiding surface 102 gradually extend towards the side wall of the dust collection box 2, during dust collection, the air flow will flow to the side wall of the dust collection box 2 under the guiding action of the first guiding surface 101 and the second guiding surface 102, so as to clean the "dead corners" of the dust collection box 2. The bottom of the dust collection baffle 1 near the bottom wall of the dust collection box 2 can be deformed under the action of the air flow. Therefore, during dust collection, the gap between the bottom wall of the dust collection baffle 1 and the bottom wall of the dust collection box 2 will increase, so that larger objects can enter from between the bottom wall of the dust collection baffle 1 and the bottom wall of the dust collection box 2 to the end of the dust collection box 2 near the air outlet 202, thereby preventing the air duct from being blocked while cleaning the "dead corners" of the dust collection box 2.

[0085] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
