Description

Technical Field

[0001] This application relates to the field of floor cleaning technology, and more specifically, to a sweeping component and cleaning equipment. Background Technology

[0002] Cleaning equipment includes robotic vacuum cleaners, vacuum cleaners, and multi-functional cleaning base stations. Most cleaning equipment is often equipped with a central cleaning component, which is used to clean up external debris and collect it into the cleaning equipment.

[0003] Existing sweeping components have suction ports, which usually require scrapers to scoop up trash from the ground and suck it into the cleaning equipment. However, the suction force at the suction port is weak in the existing technology, resulting in low dust removal efficiency of the sweeping components. Utility Model Content

[0004] The main objective of this application is to provide a mid-sweeping component and cleaning equipment to at least solve the problem of low dust removal efficiency of mid-sweeping components in the prior art.

[0005] According to one aspect of this application, a mid-scan component is provided, comprising:

[0006] The outer casing has a mounting groove and a suction port, and the suction port is connected to the mounting groove.

[0007] A cleaning component, which is rotatably mounted in the mounting slot;

[0008] A scraping section is disposed on the outer periphery of the suction port;

[0009] A stop component is provided on the outer periphery of the suction port, and the scraping part and the stop component are arranged along the circumferential direction of the suction port, and the scraping part and the stop component surround each other to form a stop structure.

[0010] Furthermore, the stop component includes a blocking part and a stop part, the blocking part and the stop part are arranged along the circumferential direction of the suction port, and the blocking part, the stop part and the scraping part surround to form the stop structure.

[0011] Furthermore, the suction port includes a rectangular opening, the rectangular opening having a first side and a second side parallel to and opposite to the rotation axis of the cleaning component, the rectangular opening also having a third side connected to a first end of the first side and a first end of the second side, and a fourth side connected to a second end of the first side and a second end of the second side, one of the stop portion and the scraping portion being disposed on the first side, and the other being disposed on the second side;

[0012] The barrier portion includes at least two barrier members, at least one of the barrier members is disposed on the third side, and at least one of the barrier members is disposed on the fourth side.

[0013] Furthermore, the third side is provided with at least one first groove, the first groove extending from a first end near the first side to a first end near the second side, and each of the first grooves is provided with a corresponding barrier.

[0014] At least one second groove is provided on the fourth side, the second groove extending from the second end near the first side to the second end near the second side, and a barrier member is provided in each of the second grooves.

[0015] Furthermore, the stop portion includes a flexible baffle, which is disposed on the first side and is inclined in a direction close to the second side;

[0016] The scraping part includes a scraper, which is disposed on the second side and is inclined in a direction close to the first side.

[0017] Furthermore, the barrier portion includes a barrier member, which includes a brush member composed of multiple bristles.

[0018] Furthermore, the flexible baffle is a flat baffle.

[0019] Furthermore, the flexible baffle includes multiple sub-plates, which are spaced apart along the rotation axis of the cleaning component.

[0020] Furthermore, along the height direction of the middle sweeping assembly, the vertical distance L between the lowest point of the stop component and the lowest point of the scraping part satisfies the following relationship: 0.15mm≤L≤0.25mm.

[0021] On the other hand, this application also provides a cleaning device, which includes the above-described intermediate sweeping component.

[0022] Compared to existing technologies, this application includes a stop component located on the outer periphery of the suction port. The scraping part and the stop component are arranged along the circumferential direction of the suction port, forming a stop structure. This means that when the suction port is operating, the stop structure on its outer periphery reduces the gap area around the suction port, thereby improving the suction effect of the suction port. This makes it easier for debris on the ground to be sucked into the cleaning equipment, thus improving the dust removal efficiency of the sweeping component to a certain extent.

[0033] The background section mentions that the suction force at the suction port 101 in the prior art is relatively weak. This is because when the sweeping component 1 cleans the ground, there are many gaps around the suction port 101 during suction, which reduces the suction force of the suction port 101. When the suction force of the suction port 101 is low, it will be difficult for the suction port 101 to absorb the garbage on the ground into the cleaning equipment.

[0034] See Figures 1 to 4 As shown in the embodiment of this application, a cleaning device is provided, which includes a central sweeping assembly 1, wherein the central sweeping assembly 1 includes a housing 10, a cleaning component 20, a scraping part 30, and a stop component 40.

[0035] The outer casing 10 has a mounting groove 102 and a suction port 101. The suction port 101 is connected to the mounting groove 102. The cleaning component 20 is rotatably mounted in the mounting groove 102. The scraping part 30 is disposed on the outer periphery of the suction port 101. The stop component 40 is disposed on the outer periphery of the suction port 101. The scraping part 30 and the stop component 40 are arranged along the circumferential direction of the suction port 101. The scraping part 30 and the stop component 40 surround each other to form a stop structure.

[0036] In this embodiment, when the cleaning device cleans the floor, the scraper 30 contacts the floor, scraping up the debris. Then, the suction port 101 generates suction on the debris outside the sweeping assembly 1, causing the debris to be drawn into the cleaning device. Compared to the prior art, this embodiment includes a stop component 40, which is located on the outer periphery of the suction port 101. The scraper 30 and the stop component 40 are arranged along the circumferential direction of the suction port 101, forming a stop structure. This means that when the suction port 101 is working, the stop structure reduces the gap area around the suction port 101, thereby improving the suction effect of the suction port 101. This makes it easier for debris on the floor to be drawn into the cleaning device, thus improving the dust removal efficiency of the sweeping assembly 1 to a certain extent.

[0037] Furthermore, the stop component 40 includes a blocking part 42 and a stop part 41, which are arranged along the circumferential direction of the suction port 101, and the blocking part 42, the stop part 41 and the scraping part 30 surround each other to form a stop structure.

[0038] Specifically, in this embodiment, the stop part 41 is used to stop the garbage on the cleaning surface. That is, after the scraper part 30 scrapes up the garbage on the ground, the stop part 41 can limit the garbage and prevent it from splashing to other areas, so that the garbage scraped by the scraper part 30 can be sucked into the suction port 101. In addition, in this embodiment, the barrier part 42 plays a role in restricting the airflow. That is, when the suction port 101 is suctioning, because the barrier part 42 is provided around the suction port 101, the airflow around the suction port 101 is difficult to pass through the barrier part 42 and enter the suction port 101, thereby improving the suction capacity of the suction port 101. At the same time, in this embodiment, the barrier part 42, the stop part 41 and the scraper part 30 form a stop structure, which, while improving the suction capacity of the suction port 101, also ensures that the garbage scraped by the scraper part 30 can be accurately sucked into the suction port 101.

[0039] In some embodiments, the suction port 101 includes a rectangular opening having a first side 1011 and a second side 1012 parallel to and opposite to the rotation axis of the cleaning component 20. The rectangular opening also has a third side 1013 connected to the first end of the first side 1011 and the first end of the second side 1012, and a fourth side 1014 connected to the second end of the first side 1011 and the second end of the second side 1012. One of the stop portion 41 and the scraping portion 30 is disposed on the first side 1011, and the other is disposed on the second side 1012. The blocking portion 42 includes at least two blocking members 421, at least one blocking member 421 is disposed on the third side 1013, and at least one blocking member 421 is disposed on the fourth side 1014.

[0040] In one specific embodiment, as shown in the appendix Figure 3 As shown, a stop portion 41 is disposed on the first side 1011, a scraping portion 30 is disposed on the second side 1012, and a blocking member 421 is disposed on the third side 1013 and the fourth side 1014, respectively. The stop portion 41 of the first side 1011, the blocking member 421 of the third side 1013, the scraping portion 30 of the second side 1012, and the blocking member 421 of the fourth side 1014 form a stop structure, thereby restricting the airflow into the suction port 101 and thus improving the suction force of the suction port 101. Of course, in some other embodiments, the suction port 101 can also be a circular opening or an elliptical opening. It is only necessary to provide a stop structure around the outer perimeter of the circular or elliptical opening to improve the suction force of the suction port 101.

[0041] Furthermore, the third side 1013 is provided with at least one first groove 1015, the first groove 1015 extends from a first end near the first side 1011 to a first end near the second side 1012, and a barrier member 421 is provided in each first groove 1015; the fourth side 1014 is provided with at least one second groove 1016, the second groove 1016 extends from a second end near the first side 1011 to a second end near the second side 1012, and a barrier member 421 is provided in each second groove 1016.

[0042] Specifically, the first groove 1015 and the second groove 1016 are used to fix the barrier 421, preventing the barrier 421 from falling off the mid-scan assembly 1 under external force. In this embodiment, the first groove 1015 extends from a first end near the first side 1011 to a first end near the second side 1012, and the second groove 1016 extends from a second end near the first side 1011 to a second end near the second side 1012, thereby limiting the length of the barrier 421 installed in the first groove 1015 and the second groove 1016, avoiding the barrier 421 from being too long and thus increasing the manufacturing cost of the mid-scan assembly 1. In some embodiments, the length of the barrier 421 is the same as the length of the first groove 1015 or the second groove 1016, thereby making the stop structure a relatively sealed structure, which to a certain extent improves the suction force of the suction port 101. Of course, in other embodiments, for example, when the suction port 101 is smaller, the suction force of the suction port 101 is relatively concentrated. In this case, the length of the barrier 421 can be relatively smaller, thereby saving the manufacturing cost of the intermediate scanning component 1 to a certain extent. In this embodiment, the barrier 421 is a flocked sheet. In some embodiments, the barrier 421 can also be a sealing silicone.

[0043] In some embodiments, the barrier 421 includes a brush component composed of multiple bristles. Specifically, the multiple bristles can be arranged sequentially or in an array along a predetermined direction to form the brush component. Due to the arrangement of multiple bristles, it is difficult for external airflow to pass through the multiple bristles and enter the suction port 101, thereby improving the suction force of the suction port 101 to a certain extent. At the same time, the brush component makes flexible contact with other objects, so the brush component is not easily damaged, thereby improving the service life of the intermediate sweeping assembly 1.

[0044] Furthermore, the stop portion 41 includes a flexible baffle 411, which is disposed on the first side 1011 and is inclined in a direction close to the second side 1012; the scraping portion 30 includes a scraper 31, which is disposed on the second side 1012 and is inclined in a direction close to the first side 1011.

[0045] It is clear that when the cleaning equipment cleans the floor, it moves along the direction from the second side 1012 to the first side 1011. Therefore, the scraper 31 is set to tilt towards the first side 1011 to facilitate scraping up the debris on the floor. The flexible baffle 411 is tilted towards the second side 1012 to block the debris lifted by the scraper 31, preventing debris from passing through the flexible baffle 411 and reducing the cleaning efficiency of the cleaning equipment. On the other hand, in this embodiment, the stop part 41 is made of a flexible baffle 411. Thanks to the flexibility and elasticity of the flexible baffle 411, the contact between the flexible baffle 411 and the debris is flexible, thereby improving the service life of the flexible baffle 411.

[0046] To prevent interference between the cleaning component 20 and the flexible baffle 411, which could lead to frictional damage between the flexible baffle 411 and the cleaning component 20, a first gap 103 is provided between the flexible baffle 411 and the cleaning component 20 in this embodiment.

[0047] Specifically, in this embodiment, the cleaning component 20 can be a roller brush or a combination of a roller and a mop. When the cleaning component 20 is a roller brush or a combination of a roller and a mop, no matter what position the cleaning component 20 rotates to, there is a first gap 103 between the cleaning component 20 and the flexible baffle 411, thereby preventing interference between the cleaning component 20 and the flexible baffle 411.

[0048] In some embodiments, the flexible baffle 411 is a flat baffle. Benefiting from the high impact resistance of flat baffles, they are less likely to detach from or be damaged by the central sweeping assembly 1 after being subjected to external forces, thus improving the service life of the flexible baffle 411 when blocking debris. Furthermore, flat baffles are easier to standardize and produce, resulting in lower production costs. In other embodiments, the flexible baffle 411 can be an arc-shaped baffle. The arc-shaped structure of the arc-shaped baffle reduces interference with gas flow, thereby reducing noise generated on the arc-shaped baffle. Additionally, due to the arc-shaped structure, the arc-shaped baffle has fewer right-angle gaps, which can, to some extent, prevent hair or cables from getting stuck on the arc-shaped baffle.

[0049] Furthermore, the flexible baffle 411 includes multiple sub-plates 4111, which are spaced apart along the rotation axis of the cleaning component 20.

[0050] Understandably, when the cleaning equipment is cleaning the ground, there may be large pieces of debris on the ground. These large pieces of debris cannot be sucked into the cleaning equipment, partly because the suction force of the suction port 101 is insufficient, and partly because if large pieces of debris are sucked into the cleaning equipment, the cleaning component 20 may get stuck. Therefore, in this embodiment, the flexible baffle 411 includes multiple sub-plates 4111, and the multiple sub-plates 4111 are spaced apart along the rotation axis of the cleaning component 20. This means that when there is large debris on the ground, the large debris can pass through the gap between two adjacent sub-plates 4111, or the large debris can cause the sub-plates 4111 to deform flexibly and pass through the sub-plates 4111, thereby preventing large debris from entering the mounting groove 102 and causing the cleaning component 20 to get stuck.

[0051] As attached Figure 4 As shown, along the height direction of the middle scanning component 1 (as shown in the attached diagram) Figure 4 In the Z direction, the vertical distance L between the lowest point of the stop component 40 and the lowest point of the scraping part 30 satisfies the following relationship: 0.15mm≤L≤0.25mm.

[0052] In actual operation of the cleaning component 1, the scraping part 30 needs to be in direct contact with the garbage on the ground. That is to say, the lowest point of the scraping part 30 needs to be in direct contact with the ground. The stop component 40, namely the stop part 41 and the barrier part 42, is only used to improve the suction force of the suction port 101. If the stop part 41 and the barrier part 42 are in contact with the ground, on the one hand, the stop part 41 and the barrier part 42 are easily damaged, and on the other hand, it will affect the smoothness of the movement of the cleaning equipment. Therefore, in this embodiment, there is a vertical distance L between the lowest point of the stop component 40 and the lowest point of the scraping part 30. In this embodiment, L satisfies the relationship: 0.15mm ≤ L ≤ 0.25mm. When L is within the above range, the vertical distance between the lowest point of the stop component 40 and the lowest point of the scraping part 30 will not be too large. Therefore, the stop structure formed by the stop component 40 and the scraping part 30 can effectively block the airflow and improve the adsorption capacity of the suction port 101 to a certain extent. At the same time, the vertical distance between the lowest point of the stop component 40 and the lowest point of the scraping part 30 will not be too small, thereby preventing the stop component 40 from easily colliding with the protruding garbage on the ground. However, when L is less than 0.15mm, the distance between the stop component 40 and the ground is too close, and the stop component 40 is prone to colliding with the protruding garbage on the ground, resulting in damage to the stop component 40. When L is greater than 0.25mm, the stop component 40 is too high above the ground. In this case, the stop structure formed by the stop component 40 and the scraping part 30 has poor ability to block the airflow around the suction port 101, which may prevent the suction port 101 from sucking up the debris scraped by the scraping part 30 into the cleaning device. The value of L can be 0.15mm, 0.16mm, 0.17mm, 0.18mm, 0.19mm, 0.20mm, 0.21mm, 0.22mm, 0.23mm, 0.24mm, and 0.25mm.

[0053] In summary, in the sweeping assembly 1 and cleaning equipment of this application, the scraping part 30 and the stop component 40 are arranged circumferentially along the suction port 101, and the scraping part 30 and the stop component 40 form a stop structure, so that when the suction port 101 is suctioning, the stop structure can prevent the airflow around the suction port 101 from entering the suction port 101, thereby improving the suction capacity of the suction port 101. On the other hand, the stop component 40 of this application includes a blocking part 42 and a stop part 41. The blocking part 42, the stop part 41 and the scraping part 30 surround to form a stop structure. The blocking part 42 is used to prevent the airflow around the suction port 101 from entering the suction port 101, and the stop part 41 is used to stop the garbage scraped up by the scraping part 30, so as to prevent the garbage from splashing to other areas and being sucked into the cleaning equipment by the suction port 101. In this application, the stop part 41 includes a flexible baffle 411, and a first gap 103 exists between the flexible baffle 411 and the cleaning component 20 to avoid interference between the flexible baffle 411 and the cleaning component 20. Furthermore, using the flexible baffle 411 can improve the service life of the stop part 41. Finally, there is a vertical distance L between the lowest point of the stop component 40 and the lowest point of the scraping part 30, and the vertical distance L satisfies the relationship: 0.15mm ≤ L ≤ 0.25mm. This not only improves the suction capacity of the suction port 101 but also prevents the stop component 40 from contacting protruding debris on the ground, thus avoiding damage to the stop component 40.
