Description

Technical Field

[0001] This application relates to the field of electrical equipment technology, and in particular to a dust box housing, dust box structure, cleaning device, and cleaning system. Background Technology

[0002] With the advancement of technology and the improvement of living standards, cleaning devices such as sweepers are being used more and more widely in people's lives and production. These cleaning devices can automatically clean the ground and other surfaces that need cleaning, thereby freeing people from heavy housework and improving their living environment.

[0003] However, due to the limited space in the dustbin of the cleaning device, users need to manually clean it after a period of operation, which is inconvenient. To address this issue, base stations equipped with dust collection bins have emerged. After the cleaning device is connected to the base station, the base station can automatically collect the dust and debris temporarily stored in the dustbin, significantly reducing the frequency of manual cleaning and making the cleaning device more convenient to use.

[0004] However, when some existing cleaning devices perform self-cleaning by discharging waste, some oddly shaped waste (such as sunflower seed shells, hair clumps, small particles, etc.) can easily get stuck in the cleaning device, causing the cleaning device to malfunction. Utility Model Content

[0005] Therefore, it is necessary to provide a dust box housing, dust box structure, cleaning device, and cleaning system to address the problem of debris jamming during self-cleaning of cleaning devices.

[0006] A dustbin housing, comprising:

[0007] The main housing has an adjacently arranged receiving cavity and a dust exhaust duct, and a dust exhaust port connecting the receiving cavity and the dust exhaust duct; and

[0008] A dust exhaust cover includes a cover body and a windproof component. The cover body is installed on the main housing and located on the side of the dust exhaust port facing the dust exhaust duct. The windproof component protrudes from the side of the cover body facing away from the dust exhaust port.

[0009] The dust exhaust cover can switch between a first state of closing the dust exhaust port and a second state of opening the dust exhaust port, and when the dust exhaust cover is in the second state, the windproof member abuts against the duct wall of the dust exhaust duct.

[0010] When the dust discharge cover is in the second state, the windproof component of the dust box housing abuts against the duct wall of the dust discharge duct, thereby optimizing the airflow direction in the dust discharge duct and effectively preventing dust and debris from being trapped in the gap between the cover body and the duct wall of the dust discharge duct. This prevents the dust discharge cover from being stuck by debris and unable to return to the first state, thus ensuring the normal operation of the cleaning device.

[0011] In one embodiment, the main housing includes:

[0012] Bottom wall of the shell;

[0013] The housing sidewall extends from the edge of the housing bottom wall toward one side of the housing bottom wall;

[0014] The air duct sidewall extends from the edge of a portion of the housing sidewall away from the bottom wall of the housing toward the side where the bottom wall of the housing is located;

[0015] The bottom wall of the housing and the side wall of the housing together define the receiving cavity, and the side wall of the housing and the side wall of the air duct together define the dust exhaust air duct. The dust exhaust port is opened on the side wall of the housing that connects to the side wall of the air duct. When the dust exhaust cover is in the second state, the windproof member abuts against the side wall of the air duct.

[0016] Thus, the dust exhaust duct is located on one side of the receiving cavity and is connected to the receiving cavity through the dust exhaust port. The wind baffle abuts against the side wall of the duct, which can effectively prevent the airflow from the receiving cavity from flowing from both sides of the dust exhaust cover in the first direction to the back of the dust exhaust cover facing away from the dust exhaust port.

[0017] In one embodiment, the dust exhaust cover further includes a connecting shaft, which passes through one end of the cover body along a first direction and is installed at the connection between the housing sidewall and the air duct sidewall.

[0018] Thus, the cover body is rotatably connected to the main housing via a connecting shaft, allowing it to open and close automatically under negative pressure.

[0019] In one embodiment, the dust cover includes two wind deflectors located on opposite sides of the cover body in the first direction, and each wind deflector extends from one end of the cover body near the housing sidewall toward the other end of the cover body away from the housing sidewall.

[0020] In this way, the wind deflector can effectively prevent the airflow from the receiving cavity from flowing from both sides of the dust discharge cover in the first direction to the back of the dust discharge cover facing away from the dust discharge port. Instead, the airflow directly passes through the dust discharge cover towards the front of the dust discharge port and enters the base station. This effectively prevents the problem of garbage getting stuck when passing through both sides of the dust discharge cover, so that the dust discharge cover can switch normally between the first state and the second state, ensuring the normal operation of the cleaning device with the dust box housing.

[0021] In one embodiment, the dust cover is interference-fitted with the edge of the dust outlet.

[0022] Thus, when the dust exhaust cover is in the first state of closing the dust exhaust port, it can effectively prevent dust from leaking between the dust exhaust cover and the dust exhaust port.

[0023] In one embodiment, the edge of the dust outlet is provided with a circumferentially extending sealing rib, which is interference-fitted with the dust outlet cover; and / or

[0024] The dust discharge cover also includes a sealing element, which is disposed circumferentially on the edge of the cover body and is interference-fitted with the edge of the dust discharge port.

[0025] Thus, by using sealing ribs and / or seals to achieve a sealing fit between the dust outlet and the dust cover, dust leakage between the dust cover and the dust outlet can be effectively prevented.

[0026] In one embodiment, the dust cover further includes a reset member for applying a force to the cover body to switch from the second state to the first state.

[0027] Thus, under the negative pressure generated by the base station, the dust exhaust cover overcomes the force applied by the reset component and switches from the first state to the second state to open the dust exhaust port. When the negative pressure of the base station disappears, the dust exhaust cover switches from the second state to the first state under the action of the reset component to close the dust exhaust port.

[0028] In one embodiment, the cover body has a mounting groove corresponding to the reset member, and the mounting groove is located on the side of the cover body facing away from the dust outlet.

[0029] Thus, the reset component is installed on the cover body through the mounting groove. Since the mounting groove is located on the side of the cover body away from the dust outlet, it can effectively prevent dust and debris from entering the interior of the cover body through the mounting groove and affecting the normal operation of the cover body and the reset component.

[0030] A dust box structure includes the aforementioned dust box shell, the dust box structure further includes a dust box cover and a filter assembly, the dust box cover is closably mounted on one side of the dust box structure, and the filter assembly is located between the dust box structure and the dust box cover and communicates with the receiving cavity.

[0031] A cleaning device includes the aforementioned dust box housing, and the cleaning device also includes a main body, the dust box housing being mounted on the main body.

[0032] A cleaning system includes the aforementioned cleaning device, the cleaning system further includes a base station, the cleaning device is detachably connected to the base station, and the dust exhaust duct is connected to the base station. Attached Figure Description

[0050] See Figure 1 and Figure 2 This application provides a cleaning system 1000, including a cleaning device 100 and a base station 300. The cleaning device 100 can move on a ground surface waiting to be cleaned and collect dust and debris on the ground, and can be detachably connected to the base station 300 after cleaning is completed. The base station 300 can be used to charge the cleaning device 100, and the base station 300 is provided with a base station dust collection channel 300a communicating with the cleaning device 100. A negative pressure can be formed in the base station dust collection channel 300a to extract the dust and debris collected in the cleaning device 100, thereby giving the cleaning device 100 a self-cleaning function.

[0051] The following description uses a floor sweeper as an example to illustrate the construction of the dustbin structure 140 of the cleaning device 100. The following embodiments are for illustrative purposes only and do not limit the technical scope of this application. It is understood that in other embodiments, the cleaning device 100 may also be other equipment equipped with the dustbin structure 140, such as a vacuum cleaner or floor scrubber, and this is not limited thereto.

[0052] Please continue reading. Figure 1 and Figure 2 The cleaning device 100 includes a main body 120 and a dust box structure 140 mounted on the main body 120. The dust box structure 140 includes a dust box housing 142, a dust box cover 144, and a filter assembly 146. The dust box cover 144 is closably connected to the dust box housing 142 to close the dust box housing 142. The filter assembly 146 is located between the dust box housing 142 and the dust box cover and communicates with the receiving cavity 141a. In a preferred embodiment, the filter assembly 146 is detachably located between the dust box housing 142 and the dust box cover 144, thereby facilitating the cleaning and replacement of the filter assembly 146.

[0053] When the cleaning device 100 is in a cleaning state, the dust and debris collected by the cleaning device 100 can be contained in the dust box housing 142. The filter assembly 146 is used to filter the dust and debris to prevent them from entering the main body 120. When the cleaning device 100 is connected to the base station 300 for waste collection, the cleaning device 100 is connected to the base station dust collection channel 300a. The dust and debris stored in the dust box housing 142 can be extracted and recycled by the base station 300, thereby achieving self-cleaning of the cleaning device 100.

[0054] Please combine Figures 1 to 3 As shown, the dust box housing 142 includes a main housing 141 and a dust discharge cover 143 installed on the main housing 141.

[0055] The main housing 141 has a hollow shell structure, with adjacent receiving cavities 141a and dust exhaust duct 141b, and a dust exhaust port 1414a connecting the receiving cavity 141a and the dust exhaust duct 141b. The dust exhaust cover 143 includes a cover body 1431 and a wind baffle 1432. The cover body 1431 is installed on the main housing 141 and located on the side of the dust exhaust port 1414a facing the dust exhaust duct 141b. The wind baffle 1432 protrudes from the cover body 1431 on the side facing away from the dust exhaust port 1414a. The dust exhaust cover 143 can switch between a first state of closing the dust exhaust port 1414a and a second state of opening the dust exhaust port 1414a. When the dust exhaust cover 143 is in the second state, the wind baffle 1432 abuts against the duct wall of the dust exhaust duct 141b.

[0056] Thus, when the cleaning device 100 is in the normal cleaning process, the dust discharge cover 143 is in the first state of closing the dust discharge port 1414a. At this time, the receiving cavity 141a cannot be connected to the dust discharge duct 141b through the dust discharge port 1414a, and the dust discharge cover 143 can prevent dust and debris in the receiving cavity 141a from entering the dust discharge duct 141b.

[0057] When the cleaning device 100 is connected to the base station 300, the dust discharge cover 143 is in the second state with the dust discharge port 1414a open. The receiving cavity 141a is connected to the dust discharge duct 141b through the dust discharge port 1414a. Therefore, the negative pressure generated by the base station 300 can form an airflow that flows from the receiving cavity 141a through the dust discharge port 1414a and the dust discharge duct 141b into the base station 300. The airflow can carry the dust and debris in the receiving cavity 141a through the dust discharge port 1414a and the dust discharge duct 141b into the dust collection channel 300a of the base station, thereby realizing the self-cleaning of the cleaning device 100.

[0058] In the dust box housing 142, when the dust discharge cover 143 is in the second state, the wind deflector 1432 abuts against the duct wall of the dust discharge duct 141b, thereby optimizing the airflow direction in the dust discharge duct 141b and effectively preventing dust and debris from accumulating in the gap between the cover body 1431 and the duct wall of the dust discharge duct 141b. This prevents the dust discharge cover 143 from being stuck by debris and unable to return to the first state, thereby ensuring the normal operation of the cleaning device 100.

[0059] Please combine Figure 3 , Figure 4 as well as Figure 5 As shown, the main housing 141 has a hollow cubic structure. In the following embodiments, the width direction of the main housing 141 is defined as the first direction (i.e., Figure 4 The X direction in the middle), the length direction of the main shell 141 is the second direction (i.e., Figure 4 The Y direction of the main shell 141 is the height direction of the third direction (i.e., the height direction of the main shell 141 is the third direction). Figure 4 In the Z direction), the first direction, the second direction, and the third direction intersect each other, and in a preferred embodiment, the first direction, the second direction, and the third direction are perpendicular to each other.

[0060] The main housing 141 includes an integrally formed bottom wall 1412, side walls, and a duct side wall 1417. The bottom wall 1412 is a flat plate structure perpendicular to a third direction. The side walls extend from the edge of the bottom wall 1412 toward one side of the bottom wall 1412. The duct side wall 1417 extends from the edge of a portion of the side wall away from the bottom wall 1412 toward the side where the bottom wall 1412 is located. Thus, the bottom wall 1412 and the side walls together define a receiving cavity 141a, and the duct side wall 1417 and the side walls together define a dust exhaust duct 141b with one open end. The dust exhaust port 1414a is opened on the side wall of the housing that connects to the duct side wall 1417.

[0061] In one specific embodiment, the housing sidewall includes a first sidewall 1413, a second sidewall 1414, a third sidewall 1415, and a fourth sidewall 1416 arranged sequentially and connected end-to-end along the circumference of the receiving cavity 141a. The first sidewall 1413 and the third sidewall 1415 are spaced apart in a first direction, and the second sidewall 1414 and the fourth sidewall 1416 are spaced apart in a second direction. The first sidewall 1413, the third sidewall 1415, and the fourth sidewall 1416 all extend from the bottom wall 1412 of the housing along a third direction. The second sidewall 1414 extends outwardly at an angle from the bottom wall 1412 of the housing in a direction away from the fourth sidewall 1416. A dust discharge port 1414a is formed on the second sidewall 1414 and is rectangular in shape. The duct sidewall 1417 is connected to the side of the second sidewall 1414 away from the bottom wall 1412 of the housing, and extends from the second sidewall 1414 toward the bottom wall 1412 of the housing in a third direction. Therefore, a dust exhaust duct 141b is formed between the duct sidewall 1417 and the second sidewall 1414, and the opening end of the dust exhaust duct 141b is located on one side of the bottom wall 1412 of the housing in the second direction.

[0062] In some embodiments, the first sidewall 1413 is further provided with a dust inlet 1413a, which is provided when the cleaning device 100 is connected to the base station 300, such as Figure 5 As shown, under the negative pressure of the base station 300, external airflow can enter the receiving cavity 141a through the dust inlet 1413a to form an airflow. In a preferred embodiment, the dust inlet 1413a is located close to the fourth side wall 1416, and the distance between the dust inlet 1413a and the fourth side wall 1416 is as small as possible. Specifically, in one embodiment, the distance between the dust inlet 1413a and the fourth side wall 1416 is greater than 0 and less than 1 mm.

[0063] Thus, by positioning the dust inlet 1413a as close as possible to the fourth side wall 1416, it can effectively prevent the formation of dead zones in the dust box housing 142 that are difficult to reach, reduce the momentum loss of the airflow in the dust inlet 1413a, and at the same time, the stepped structure formed at the edge of the dust inlet 1413a can transform the airflow into turbulent flow with higher momentum, thereby effectively preventing dust and debris from accumulating in the dead zones of the dust box housing 142 and significantly reducing the deposition of dust and debris in the dust box housing 142.

[0064] In some embodiments, a guide surface extending along a third direction is formed at the connection between the third sidewall 1415 and the fourth sidewall 1416. The cross-section of the guide surface perpendicular to the third direction is an inwardly concave arc shape. Thus, the arc-shaped guide surface reduces momentum loss during airflow, effectively preventing dust and debris residue, while simultaneously controlling the airflow direction to guide the airflow to the dust discharge port 1414a, allowing dust and debris to flow smoothly out of the dust discharge port 1414a. It is understood that the bending radius and other dimensions of the guide surface can be set as needed to meet different airflow requirements.

[0065] Please combine Figure 3 , Figure 6 as well as Figure 7 As shown, in some embodiments, the cover body 1431 has a rectangular flat plate structure. A connecting shaft 1433 is provided through one side edge of the cover body 1431. The two ends of the connecting shaft 1433 protrude from the opposite side edges of the cover body 1431. Therefore, the dust discharge cover 143 can be connected to the connection between the second side wall 1414 and the air duct side wall 1417 through the connecting shaft 1433. The central axis of the connecting shaft 1433 extends along the first direction, so that it can be switched between the first state of closing the dust discharge port 1414a and the second state of opening the dust discharge port 1414a.

[0066] As a preferred embodiment, the connecting shaft 1433 is made of a non-metallic material, thereby preventing dirt from corroding the connecting shaft 1433 and affecting the normal rotation of the cover body 1431.

[0067] Two wind baffles 1432 are protruding from the side surface of the cover body 1431 facing away from the dust discharge port 1414a. The two wind baffles 1432 are located on opposite sides of the dust discharge cover 143 in the first direction. Each wind baffle 1432 has a long strip structure and extends from the end of the dust discharge cover 143 near the second side wall 1414 to the end of the dust discharge cover 143 away from the second side wall 1414. The height of the wind baffle 1432 protruding from the cover body 1431 gradually increases from the end near the second side wall 1414 to the end away from the second side wall 1414, so that the side edge of the wind baffle 1432 away from the cover body 1431 can abut against the side wall 1417 of the air duct.

[0068] Thus, when the dust cover 143 is in the second state, the baffle 1432 abuts against the wall of the dust exhaust duct 141b, effectively preventing the airflow from the receiving cavity 141a from flowing from both sides of the dust cover 143 in the first direction to the back of the dust cover 143 facing the dust exhaust port 1414a. Instead, the airflow passes directly through the dust cover 143 towards the front of the dust exhaust port 1414a and enters the base station 300. This effectively prevents the problem of garbage getting stuck when passing through both sides of the dust cover 143, allowing the dust cover 143 to switch normally between the first and second states, ensuring the normal operation of the cleaning device 100 equipped with the dust box housing 142. It is understood that the shape, number, and position of the baffle 1432 are not limited to this and can be set as needed to meet different requirements.

[0069] In some embodiments, the dust discharge cover 143 is press-fitted with the edge of the dust discharge port 1414a, thus providing a good sealing effect. When the dust discharge cover 143 is in the first state of closing the dust discharge port 1414a, it can effectively prevent dust from leaking between the dust discharge cover 143 and the dust discharge port 1414a.

[0070] In one specific embodiment, a sealing rib 1414b protrudes from the edge of the dust discharge port 1414a toward the dust discharge duct 141b, and the sealing rib 1414b extends circumferentially along the dust discharge duct 141b. The dust discharge cover 143 also includes a sealing element 1434, which is preferably formed of a material that can undergo elastic deformation, such as rubber or sponge. The sealing element 1434 is circumferentially disposed on the edge of the cover body 1431, and the shape of the sealing element 1434 matches the shape of the dust discharge port 1414a. Therefore, the sealing rib 1414b and the sealing element 1434 are interference-fitted, thereby achieving a good sealing effect. In some other embodiments, the sealing rib 1414b extending circumferentially may only protrude from the edge of the dust discharge port 1414a, or the sealing element 1434 extending circumferentially may only be provided on the edge of the dust discharge cover 143, which can also achieve a certain sealing effect.

[0071] More specifically, in one embodiment, the cover body 1431 has a circumferentially extending limiting groove on one edge facing the dust discharge port 1414a. The shape of the sealing member 1434 matches the shape of the limiting groove, so the sealing member 1434 is embedded in the dust discharge cover 143. It is understood that the shape and installation method of the sealing member 1434 are not limited, and can be set as needed to meet different installation requirements.

[0072] In some embodiments, the dust extraction cover 143 further includes a reset member 1435, which is connected to the cover body 1431 and the connecting shaft 1433. The reset member 1435 can undergo recoverable deformation under external force, thereby applying a force to the cover body 1431 to switch from a second state to a first state. Specifically, in one embodiment, the reset member 1435 is a torsion spring sleeved on the connecting shaft 1433, and the two ends of the torsion spring are respectively fixed to the connecting shaft 1433 and the cover body 1431.

[0073] Thus, under the negative pressure generated by the base station 300, the cover body 1431 overcomes the force applied by the reset member 1435 and switches from the first state to the second state to open the dust exhaust port 1414a. When the negative pressure of the base station 300 disappears, the cover body 1431 switches from the second state to the first state under the action of the reset member 1435 to close the dust exhaust port 1414a.

[0074] Furthermore, the cover body 1431 has a mounting groove 1431a corresponding to the reset member 1435, and the mounting groove 1431a is located on the side of the cover body 1431 facing away from the dust discharge port 1414a. Thus, the reset member 1435 is mounted to the cover body 1431 through the mounting groove 1431a. Since the mounting groove 1431a is located on the side of the cover body 1431 facing away from the dust discharge port 1414a, it effectively prevents dust and debris from entering the interior of the cover body 1431 through the mounting groove 1431a and affecting the normal operation of the cover body 1431 and the reset member 1435.

[0075] In some embodiments, when the cleaning device 100 is in a cleaning state, the opening end of the dust exhaust duct 141b faces downward (i.e., towards the ground). When the cleaning device 100 is connected to the base station 300, the opening end of the dust exhaust duct 141b faces downward (i.e., towards the ground) to communicate with the base station 300. Dust and debris in the receiving cavity 141a flow out from the dust exhaust port 1414a and then pass downward through the dust exhaust duct 141b into the base station dust collection channel 300a.

[0076] The aforementioned dust box housing 142, cleaning device 100, and cleaning system 1000, through the windproof component 1432 on the dust discharge cover 143, can effectively prevent garbage from getting stuck between the dust discharge cover 143 and the duct wall of the dust discharge duct 141b, thereby ensuring that the dust discharge cover 143 can flexibly switch between the first and second states. Moreover, even if the dust discharge cover 143 gets stuck and cannot switch to the first state in an extreme situation, since the dust discharge cover 143 is located inside the dust discharge duct 141b and does not protrude from the main housing 141, the cleaning device 100 can be smoothly removed from the base station 300, and then the operator can manually remove the dust box structure 140 for maintenance. In addition, when the cleaning device 100 is in the cleaning state, since the dust discharge port 1414a and the dust discharge duct 141b face the ground, even if the dust discharge cover 143 gets stuck and cannot switch to the first state, the operator can also remove the dust box structure 140 upwards for maintenance.

[0077] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above 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.

[0078] The embodiments described above are merely illustrative of several implementation methods of this application, and 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 those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
