Description

Technical Field

[0001] The present application relates to the technical field of household appliances, and in particular to a dust collection box, a sweeping robot, and a cleaning system. Background Art

[0002] With the advancement of household appliance technology, cleaning systems capable of autonomous vacuuming, mopping, and dust collection are gradually replacing traditional manual cleaning tasks and are becoming increasingly commonplace. These cleaning systems consist of a dust collection system and a robot vacuum. When the robot vacuum is detached from the dust collection system, it can continue cleaning the surface. When connected to the dust collection system, the system collects waste from the robot vacuum.

[0003] A sweeping robot usually includes a dust box fan and a dust box. The dust box includes a dust box body and an air inlet baffle. The dust box body has a dust collecting cavity and a first air inlet and a first air outlet both connected to the dust collecting cavity. The air inlet baffle is used to close the first air inlet.

[0004] The dust collection pile includes a dust collection body, a dust collection fan mounted on the dust collection body, and a dust collection bag. The dust collection body is also equipped with an air outlet channel and an air inlet channel. When the robot vacuum is connected to the dust collection pile, the air outlet channel communicates with the first air inlet, and the air inlet channel communicates with the first air outlet. Under the action of the dust collection fan, external air flows into the dust collection chamber through the air outlet channel and the first air inlet, carrying the waste in the dust collection chamber through the first air outlet and the air inlet channel to be collected in the dust collection bag.

[0005] However, when there is a lot of garbage collected in the dust box, the garbage can easily press down the air intake baffle, causing the air intake baffle to be unable to open the first air inlet under the action of the external airflow. Furthermore, the external airflow cannot enter the dust collecting chamber and take away the garbage. This results in low dust collection reliability and efficiency of the cleaning system. Summary of the Invention

[0006] Based on this, it is necessary to provide a dust collection box, a sweeping robot and a cleaning system that can improve the dust collection reliability and dust collection efficiency in order to address the above-mentioned problems of low dust collection reliability and dust collection efficiency.

[0007] A dust collecting box, comprising:

[0008] A dust box body having a dust collecting cavity therein and a first air inlet in communication with the dust collecting cavity; and

[0009] An air inlet baffle, comprising at least two sub-baffles, each of which is rotatably connected to the dust box body;

[0010] When the air inlet baffle closes the first air inlet, each of the sub-baffles can rotate relative to the dust box body and open the first air inlet with the help of the force of the external airflow.

[0011] In one embodiment, at least two air intake shafts are further included, all of which correspond to all of the sub-baffles one by one, and each of the air intake shafts is rotatably disposed through the corresponding sub-baffle and fixedly connected to the wall edge of the first air inlet.

[0012] In one embodiment, the dust box body further includes at least two receiving ribs, and all the receiving ribs correspond to all the sub-baffles one by one;

[0013] Among them, each sub-baffle has a rotating end and a movable end arranged relatively to each other, the rotating end of each sub-baffle is rotatably connected to the dust box body, and when the air intake baffle closes the first air inlet, the movable end of each sub-baffle is supported by the corresponding supporting rib.

[0014] In one embodiment, a first air outlet communicating with the dust collecting chamber is provided on the dust box body, and all the connecting ribs and all the sub-baffles are arranged at intervals along a line connecting the first air outlet and the first air inlet.

[0015] When the air inlet baffle closes the first air inlet, the movable end of the sub-baffle farthest from the first air outlet is away from the first air outlet relative to the rotating end.

[0016] In one embodiment, when the air inlet baffle closes the first air inlet, the movable end of each sub-baffle is away from the first air outlet relative to the rotating end.

[0017] In one embodiment, at least two reset members are further included, all of which correspond to all of the sub-baffles one by one, and each of the reset members is transmission-connected between the corresponding sub-baffle and the dust box body, and is used to provide a reset force to drive the sub-baffle to cover the first air inlet.

[0018] In one embodiment, the air intake shaft further comprises at least two air intake shafts, all of which correspond to all of the sub-baffles one by one, and each of the air intake shafts is rotatably disposed through the corresponding sub-baffle and fixedly connected to the wall edge of the first air inlet;

[0019] The reset member is a torsion spring, and a relief opening is provided on one side of each sub-baffle connected to the air intake shaft. Each reset member is located in the relief opening, and each reset member is sleeved on the corresponding air intake shaft and abuts against the dust box body and the sub-baffle.

[0020] In one embodiment, an air outlet baffle is further included, and a first air outlet communicating with the dust collecting chamber is provided on the dust box body;

[0021] When the air inlet baffle closes the first air inlet, the air outlet baffle closes the first air outlet; when at least one of the sub-baffles rotates and partially opens the first air inlet, the air outlet baffle opens the first air outlet.

[0022] A sweeping robot comprises the dust collection box as described in any one of the above items.

[0023] A cleaning system comprising:

[0024] A dust collecting pile, comprising a dust collecting body and a dust collecting fan, wherein the dust collecting fan is connected to the dust collecting body, and the dust collecting body has an air outlet channel; and

[0025] As in the above-mentioned sweeping robot, when the sweeping robot is connected to the dust collecting pile, the first air inlet is connected between the air outlet channel and the dust collecting chamber;

[0026] The dust collecting fan is used to drive the external air flow through the air outlet channel and the first air inlet into the dust collecting chamber.

[0027] In the aforementioned dust box, sweeping robot, and cleaning system, the air intake baffle is divided into at least two sub-baffles. Since each sub-baffle is rotatably connected to the dust box body, when no trash is pressing on any of the sub-baffles, all of the sub-baffles can rotate with the help of external airflow and jointly open the first air inlet. When some of the sub-baffles are pressed by trash, the remaining unpressed sub-baffles can also open part of the first air inlet under the action of external airflow, thereby improving the dust collection reliability and dust collection efficiency of the dust box, sweeping robot, and cleaning system.

[0041] See also Figure 1 The present application provides a cleaning system, which includes a dust collection pile and a sweeping robot. The dust collection pile is fixed to the surface to be cleaned, and the sweeping robot is controlled to be separated from or connected to the dust collection pile. The cleaning system has a cleaning state in which the sweeping robot is separated from the dust collection pile, and a dust collection state in which the sweeping robot is connected to the dust collection pile. When the cleaning system is in the cleaning state, the sweeping robot independently walks on the surface to be cleaned and performs cleaning operations on the surface to be cleaned. When the cleaning system is in the dust collection state, the sweeping robot is connected to the dust collection pile, and the dust collection pile can collect garbage in the sweeping robot.

[0042] Specifically, the dust collection pile includes a dust collection body, a dust collection fan, and a dust collection bag. The dust collection fan and the dust collection bag are both connected to the dust collection body, and an air outlet channel and an air inlet channel are formed in the dust collection body, and the air inlet channel is connected to the dust collection bag. The sweeping robot includes a body, a dust collection box, and a dust box fan. The dust box fan and the dust collection box are both connected to the body. When the cleaning system is in the cleaning state, the sweeping robot is separated from the dust collection pile, the dust collection fan is turned off, and the dust box fan is turned on. The garbage on the surface to be cleaned is collected into the dust collection box by the action of the dust box fan. When the cleaning system is in the dust collection state, the body is connected to the dust collection body, and the dust collection box is connected between the air outlet channel and the air inlet channel. The dust box fan is turned off, and the dust collection fan is turned on. Under the action of the dust collection fan, the external air flows into the dust collection box through the air outlet channel, and carries the garbage in the dust collection box through the air inlet channel to flow into the dust collection bag for collection.

[0043] Please also refer to Figure 2 and Figure 3 The dust box 1 includes a dust box body 10 and an air inlet baffle 20. The dust box body 10 defines a dust collecting chamber 11. The dust box body 10 is provided with a first air inlet 13, a second air inlet, a first air outlet 15, and a second air outlet. The first air inlet 13, the second air inlet, the first air outlet 15, and the second air outlet are all in communication with the dust collecting chamber 11. The air inlet baffle 20 includes at least two sub-baffles 21, each of which is rotatably coupled to the dust box body 10. When the air inlet baffle 20 closes the first air inlet 13, each sub-baffle 21 can rotate relative to the dust box body 10 and open the first air inlet 13 due to the force of external airflow.

[0044] Specifically, when the cleaning system is in the cleaning state, the first air inlet 13 and the first air outlet 15 are both closed, and the second air inlet and the second air outlet are both open. The dust collection fan is turned off, and the dust box fan is started. Under the action of the dust box fan, the garbage on the surface to be cleaned can follow the external air flow through the second air inlet into the dust collection chamber 11, and then be separated in the dust collection chamber 11. The separated external air flow is discharged to the outside of the sweeping robot through the second air outlet, and the separated garbage is concentrated in the dust collection chamber 11. After the cleaning state is completed, the sweeping robot returns to the dust collection pile, and the body is connected to the dust collection body, and the cleaning system switches to the dust collection state. When the cleaning system is in the dust collection state, the first air inlet 13 is connected between the air outlet channel and the dust collection chamber 11, and the air inlet channel is connected between the first air outlet 15 and the dust bag. At this time, the dust box fan is turned off, and external garbage cannot enter the dust collection chamber 11 through the second air inlet. The dust collection fan starts, driving the external airflow out through the air outlet channel and opening the air inlet baffle 20. The external airflow then flows into the dust collection chamber 11 through the first air inlet 13. The external airflow then carries the dust in the dust collection chamber 11 through the air inlet channel and into the dust collection bag, where the dust is collected.

[0045] In traditional sweeping robots, the air intake baffle 20 is a whole piece. When the air intake baffle 20 is pressed by garbage, the air intake baffle 20 cannot be rotated and open the first air inlet 13 with the help of the force of the external airflow. In the present application, the air intake baffle 20 is divided into at least two sub-baffles 21. Since each sub-baffle 21 is rotatably connected to the dust box body 10, when there is no garbage pressing on any sub-baffle 21, all the sub-baffles 21 can be rotated inward with the help of the external airflow and fully open the first air inlet 13 together. When part of the sub-baffles 21 are pressed by garbage, the remaining sub-baffles 21 that are not pressed can also open part of the first air inlet 13 under the action of the external airflow, thereby improving the dust collection reliability and dust collection efficiency of the cleaning system. Moreover, since the external air flow flows in from the first air inlet 13 and flows out from the first air outlet 15, and since the external air flow passes through the dust collecting chamber 11, compared with other methods of directly sucking away the garbage in the dust collecting chamber 11 through negative pressure, there is no dust collection dead corner, and it has a better dust collection effect.

[0046] As can be understood, since each sub-baffle 21 is smaller than a conventional air inlet baffle 20, external airflow more easily drives the individual sub-baffles 21 to rotate, allowing the first air inlet 13 to open more quickly and easily. Consequently, the dust box 1 has better dust collection efficiency. Furthermore, due to the smaller area of each sub-baffle 21, eddies are less likely to form on its leeward side during the flow of external air into the dust collection chamber 11, resulting in less wind loss.

[0047] It is worth mentioning that due to the provision of at least two sub-baffles 21, the external airflow can be blown into the dust collecting chamber 11 from multiple directions, thereby avoiding the occurrence of dust collection dead corners, and making the cleaning system have a better dust collection effect.

[0048] Specifically, there can be two or more sub-baffles 21, and multiple sub-baffles 21 can be arranged side by side along a fixed direction, or can be arranged at circumferential intervals along the first air inlet 13. It is only necessary to ensure that each sub-baffle 21 can rotate inward under the action of external airflow and open the first air inlet 13.

[0049] Please also refer to Figure 4 In some embodiments, the dust box 1 further includes at least two air inlet shafts 30, each corresponding to each of the sub-baffles 21. Each air inlet shaft 30 is rotatably disposed through its corresponding sub-baffle 21 and is fixedly connected to the edge of the first air inlet 13. Under the influence of external airflow, each sub-baffle 21 can rotate inward about its corresponding air inlet shaft 30 to fully open the first air inlet 13. The rotational connection between each sub-baffle 21 and the dust box body 10 via its corresponding air inlet shaft 30 is relatively simple, thereby improving the assembly efficiency of the dust box 1.

[0050] Of course, in other embodiments, the manner in which each sub-baffle 21 is rotatably connected to the dust box body 10 is not limited to the above-mentioned one. For example, the sub-baffle 21 and the dust box body 10 may also be rotatably connected using a spherical pair, a hinge, or other means.

[0051] In some embodiments, the dust box body 10 further includes at least two connecting ribs 17, and all connecting ribs 17 correspond one-to-one with all sub-baffles 21. Each sub-baffle 21 has a rotating end and a movable end that are relatively disposed. The rotating end of each sub-baffle 21 is rotatably connected to the dust box body 10. When the air intake baffle 20 closes the first air inlet 13, the movable end of each sub-baffle 21 is connected to the corresponding connecting rib 17. In other words, when the air intake baffle 20 completely closes the first air inlet 13, the movable end of each sub-baffle 21 can be connected to the top of the corresponding connecting rib 17. Under the action of the connecting member and the air intake shaft 30, when the air intake baffle 20 closes the first air inlet 13, each sub-baffle 21 cannot rotate outside the dust collection chamber 11, thereby ensuring the reliability of the closure of the first air inlet 13. In this way, when the cleaning system is in the cleaning state, it helps to prevent the garbage in the dust collecting chamber 11 from leaking to the outside through the first air inlet 13, which may lead to poor cleaning effect.

[0052] Furthermore, the dust box body 10 is provided with a first air outlet 15 in communication with the dust collecting chamber 11, and all the supporting ribs 17 and all the sub-baffles 21 are spaced apart along the line connecting the first air outlet 15 and the first air inlet 13. Specifically, when the air inlet baffle 20 closes the first air inlet 13, the movable end of the sub-baffle 21 farthest from the first air outlet 15 is away from the first air outlet 15 relative to the rotating end. Therefore, when the cleaning system is in the dust collection state, the sub-baffle 21 farthest from the first air outlet 15 can rotate and open the first air inlet 13 under the action of external airflow. Moreover, under the guidance of the sub-baffle 21 farthest from the first air outlet 15, the external airflow can blow toward the end surface farthest from the first air outlet 15 in the direction of the line connecting the first air outlet 15 and the first air inlet 13. Furthermore, as the air flows, the garbage between the two oppositely arranged end surfaces in the direction of the line connecting the first air outlet 15 and the first air inlet 13 can be completely removed, so that the cleaning system has a better dust collection effect. Specifically, the path of the external air flow flowing in through the first air inlet 13 and flowing out of the first air outlet 15 through the dust collecting chamber 11 is as follows: Figure 2 and Figure 3 Direction indicated by the arrow.

[0053] Preferably, when the air inlet baffle 20 closes the first air inlet 13, the movable end of each sub-baffle 21 is farther away from the first air outlet 15 than the rotating end. Therefore, under the guidance of each sub-baffle 21, the external air flow can be blown toward the end surface farthest from the first air outlet 15 in the direction of the line connecting the first air outlet 15 and the first air inlet 13, thereby further improving the dust collection effect of the cleaning system.

[0054] Of course, in some other embodiments, when the air inlet baffle 20 closes the first air inlet 13, the rotating ends of some sub-baffles 21 may be arranged farther away from the first air outlet 15 than their respective movable ends, while the movable ends of the remaining sub-baffles 21 may be arranged farther away from the first air outlet 15 than their respective rotating ends.

[0055] In some embodiments, the dust box 1 further includes at least two reset members 40, all of which correspond one-to-one to all of the sub-baffles 21. Each reset member 40 is transmission-connected between the corresponding sub-baffle 21 and the dust box body 10, and is used to provide a reset force that drives the sub-baffle 21 to cover the first air inlet 13. When the dust collection blower stops working, each sub-baffle 21 can rotate under the action of the corresponding reset member 40 until the movable end of each sub-baffle 21 is supported on the corresponding supporting rib 17. In other words, the air inlet baffle can automatically close the first air inlet 13. In this way, when the cleaning system is in the cleaning state, it helps prevent garbage in the dust collection chamber 11 from leaking to the outside through the first air inlet 13, thereby ensuring a better cleaning effect of the cleaning system.

[0056] Preferably, the reset member 40 is a torsion spring. A clearance opening 212 is provided on one side of each sub-baffle 21 connected to the air inlet shaft 30. Each reset member 40 is located within the clearance opening 212, and each reset member 40 is sleeved on the corresponding air inlet shaft 30 and abuts against the dust box body 10 and the sub-baffle 21. Each sub-baffle 21 automatically covers the first air inlet 13 under the torsional force of the reset member 40. By arranging each reset member 40 within the corresponding clearance opening 212, each reset member 40 does not occupy additional space. On the one hand, it can reduce the obstruction of the external airflow by each reset member 40, allowing the external airflow to flow smoothly into the dust collection chamber 11 and take effect, thereby enabling the sweeping robot to have better dust collection efficiency and dust collection efficiency. On the other hand, it can also improve the aesthetics and compactness of the dust collection box 1.

[0057] Of course, in other embodiments, the specific structure of the reset member 40 is not limited to the above one. For example, the reset member 40 can also be a compression spring or a tension spring, and each sub-baffle 21 can automatically cover the first air inlet 13 under the action of the compression force or tension force of the reset member 40.

[0058] Please also refer to Figure 5 The dust box 1 also includes an air outlet baffle 50, and the dust box body 10 is provided with a first air outlet 15 connected to the dust collecting chamber 11. When the air inlet baffle 20 closes the first air inlet 13, the air outlet baffle 50 closes the first air outlet 15. When the cleaning system is in a cleaning state, it can prevent the garbage in the dust collecting chamber 11 from leaking to the outside through the first air outlet 15 and polluting the external environment again. Therefore, the sweeping robot has a better cleaning effect. When at least one sub-baffle 21 rotates and opens part of the first air inlet 13, the air outlet baffle 50 opens the first air outlet 15. Therefore, the garbage in the dust collecting chamber 11 can be collected in the dust bag under the action of the external airflow.

[0059] Preferably, the air outlet baffle 50 is rotatably connected to the dust box body 10. The air outlet baffle 50 opens or closes the dust removal port by rotating. Specifically, the air outlet baffle 50 can be rotatably connected to the dust box body 10 via an air outlet shaft 70, a spherical pair, a hinge, or other structure.

[0060] Preferably, the dust box 1 further includes an elastic member 60 for providing a driving force to drive the air outlet baffle 50 to close the first air outlet 15. When dust collection is completed, the dust collection fan stops operating, and the air outlet baffle 50 automatically closes the first air outlet 15 under the action of the elastic member 60. This prevents the dust in the dust collection chamber 11 from leaking to the outside through the first air outlet 15 when the cleaning system is in the cleaning state.

[0061] Specifically, the elastic member 60 may be a torsion spring, a compression spring, a tension spring, etc. It only needs to ensure that the elastic member 60 can drive the air outlet baffle 50 to automatically close the first air outlet 15 .

[0062] In the dust box 1, sweeping robot, and cleaning system described above, the air intake baffle 20 is divided into at least two sub-baffles 21. Since each sub-baffle 21 is rotatably connected to the dust box body 10, when no garbage is pressing on any of the sub-baffles 21, all of the sub-baffles 21 can rotate with the help of external airflow and jointly open the first air inlet 13. When some of the sub-baffles 21 are pressed by garbage, the remaining sub-baffles 21 that are not pressed can also open part of the first air inlet 13 under the action of external airflow, thereby improving the dust collection reliability and dust collection efficiency of the dust box 1, sweeping robot, and cleaning system.

[0063] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0064] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
