Dust box shell, dust box structure, cleaning device and cleaning system

Abstract

This application relates to a dust box housing, a dust box structure, a cleaning device, and a cleaning system. The dust box housing includes a lower dust box shell, which includes a bottom wall and a side wall. The side wall surrounds the bottom wall circumferentially to form a receiving cavity with one end open in a first direction. A dust inlet is provided on one side of the side wall in a second direction, and a dust outlet is provided on one side of the side wall in a third direction. The dust inlet and the dust outlet are interconnected to form an airflow channel. The dust inlet is located away from the dust outlet in the third direction, and the first, second, and third directions intersect each other. Because the dust inlet is located away from the dust outlet, the dust box housing effectively prevents dead zones from forming within the dust box housing, reduces momentum loss of the airflow at the dust inlet, and significantly reduces the deposition of dust and debris in the dust box housing.

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 increasingly widely used in people's lives and production. However, due to the limited dustbin space of the sweeper itself, it is necessary to manually clean the sweeper after a period of operation. Therefore, base stations equipped with dust collection bins have emerged. The base station can automatically collect the dust and debris temporarily stored in the sweeper's dustbin, significantly reducing the frequency of manual cleaning and bringing convenience to the use of sweepers.

[0003] At that time, due to structural defects, the existing sweeping machines could not completely recycle the dust and debris in the dust box from the base station, resulting in residual dust and debris in the dust box. Utility Model Content

[0004] Therefore, it is necessary to provide a dust box shell, dust box structure, cleaning device and cleaning system to address the problem of dust and debris remaining in the dust box of a sweeping machine.

[0005] A dust box housing includes a lower dust box shell, the lower dust box shell includes a bottom wall and a side wall, the side wall surrounds the bottom wall in a circumferential direction to form a receiving cavity with one end open in a first direction, a dust inlet is provided on one side of the side wall in a second direction, and a dust outlet is provided on one side of the side wall in a third direction, the dust inlet and the dust outlet are interconnected to form an airflow channel;

[0006] Wherein, the dust inlet is located away from the dust outlet in the third direction, and the first direction, the second direction, and the third direction intersect each other.

[0007] The dust box housing described above, with the dust inlet located far from the dust outlet, effectively prevents the formation of dead zones in the airflow within the dust box housing, reducing momentum loss of the airflow at the dust inlet. At the same time, the stepped structure formed at the edge of the dust inlet transforms 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 and significantly reducing the deposition of dust and debris in the dust box housing.

[0008] In one embodiment, the distance H between the edge of the dust inlet away from the dust outlet and the side wall of the housing away from the dust outlet satisfies: 0 < H ≤ 1 mm.

[0009] In this way, the dust inlet is as close as possible to the side wall of the housing away from the dust outlet, thereby further reducing the momentum loss of the airflow at the dust inlet, more effectively preventing dust and debris from accumulating in the dead corners of the dust box housing, and further reducing the deposition of dust and debris.

[0010] In one embodiment, the housing sidewall has a guide surface extending along the first direction, the guide surface being located on the side of the housing sidewall away from the dust inlet in the second direction, and the guide surface being located on the side of the housing sidewall away from the dust outlet in the third direction;

[0011] The cross-section of the guide surface perpendicular to the first direction is arc-shaped.

[0012] In this way, the arc-shaped guide surface reduces the momentum loss of airflow during the flow process, which can effectively avoid the residue of dust and debris. At the same time, it realizes the control of airflow direction and guides the airflow to the dust discharge port, so that dust and debris can flow out smoothly from the dust discharge port.

[0013] In one embodiment, the housing sidewall is provided with multiple reinforcing ribs on the side facing the dust inlet in the third direction, and the reinforcing ribs are located on the side of the housing sidewall facing away from the receiving cavity, and multiple reinforcing cavities are defined between all the reinforcing ribs.

[0014] The formation of the reinforced cavity can improve the structural strength of the shell sidewall, prevent the lower shell of the dust box from deforming under high negative pressure, and thus ensure a good sealing effect.

[0015] In one embodiment, the dust box housing further includes a dust box upper shell, which is coupled to the end of the dust box lower shell away from the bottom wall;

[0016] The side wall of the housing away from the bottom wall is provided with a lower shell mounting groove adjacent to the reinforcing cavity, and the upper shell of the dust box is provided with a rotating shaft, which is located within the lower shell mounting groove.

[0017] Since the rotating shaft is located in the mounting groove of the lower shell on one side of the reinforcing rib, the reinforcing rib can support the rotating shaft and prevent it from shifting, which would affect the connection stability and smoothness of opening and closing between the dust box shell and the dust box cover.

[0018] A dust box structure includes a dust box cover and a dust box housing, wherein the dust box housing is provided with a rotating shaft, and the dust box cover is rotatably connected to the dust box housing through the rotating shaft.

[0019] In one embodiment, the dust box structure further includes a filter assembly disposed between the dust box housing and the dust box cover.

[0020] Thus, the filter assembly is used to filter dust and debris to prevent them from entering the main unit.

[0021] A cleaning device includes the aforementioned dust box structure.

[0022] In one embodiment, the electrical device is a sweeping machine.

[0023] A cleaning system includes the cleaning device described above, and the cleaning system further includes a base station, the cleaning device being detachably connected to the base station. Attached Figure Description

Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0041] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0042] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0043] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0044] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0045] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0046] See Figure 1 and Figure 2 The embodiments of this application provide a cleaning system, including a cleaning device 1000 and a base station. The cleaning device 1000 is detachably connected to the base station, which can be used to charge the cleaning device 1000 and can form a negative pressure to extract dust and debris collected in the cleaning device 1000.

[0047] The following description uses a floor sweeper as an example to illustrate the construction of the dustbin structure 400 of the cleaning device 1000. 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 1000 may also be other equipment equipped with the dustbin structure 400, such as a vacuum cleaner or a floor scrubber, and this is not limited thereto.

[0048] Please continue reading. Figure 1 and Figure 2 The cleaning device 1000 includes a main body 200 and a dust box structure 400 installed on the main body 200. The dust box structure 400 includes a dust box housing 410, a dust box cover 430 and a filter assembly 450. The dust box cover 430 is detachably connected to the dust box housing 410 to close the dust box housing 410. The filter assembly 450 is detachably located between the dust box housing 410 and the dust box cover 434.

[0049] Thus, when the cleaning device 1000 is in a cleaning state, the dust and debris collected by the cleaning device 1000 can be contained in the dust box housing 410, and the filter assembly 450 is used to filter the dust and debris to prevent dust and debris from entering the main body 200. When the cleaning device 1000 is connected to the base station for debris collection, the dust and debris stored in the dust box housing 410 can be extracted and collected by the base station.

[0050] Please combine Figure 3 , Figure 4 as well as Figure 5 As shown, the dustbin housing 410 has a housing structure with one end open, including a lower dustbin shell 412 and an upper dustbin shell 414 connected to each other. In the following embodiments, the height direction of the dustbin housing 410 is defined as the first direction (i.e., Figure 3The width direction of the dust box housing 410 is the second direction (i.e., the Z direction in the middle). Figure 3 The length direction of the dust box housing 410 is the third direction (i.e., the X direction in the middle). Figure 3 In the Y 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.

[0051] Specifically, the dust box lower shell 412 has a shell structure with one end open, including a shell bottom wall 4121 and a shell side wall. The shell side wall surrounds the shell bottom wall 4121 in the circumferential direction to form a receiving cavity 412a with one end open in the first direction. The receiving cavity 412a is used to contain dust and debris collected by the cleaning device 1000 during the process.

[0052] Furthermore, a dust inlet 4122a is provided on one side of the housing sidewall in the second direction, and a dust outlet 4123a is provided on the other side of the housing sidewall in the third direction. The dust inlet 4122a and the dust outlet 4123a are interconnected to form an airflow channel. The dust inlet 4122a is located away from the dust outlet 4123a in the third direction.

[0053] In the aforementioned dust box housing 410, since the dust inlet 4122a is located far from the dust outlet 4123a, it can effectively prevent the formation of dead corners in the airflow within the dust box housing 410, reduce the momentum loss of the airflow at the dust inlet 4122a, and at the same time, the stepped structure formed at the edge of the dust inlet 4122a can transform the airflow into turbulent flow with higher momentum, thereby effectively preventing dust and debris from accumulating in the dead corners of the dust box housing 410, and significantly reducing the deposition of dust and debris in the dust box housing 410.

[0054] like Figure 4 As shown, the distance H between the edge of the dust inlet 4122a away from the dust outlet 4123a and the side wall of the housing away from the dust outlet 4123a satisfies: 0 < H ≤ 1 mm.

[0055] Thus, the dust inlet 4122a is positioned as close as possible to the side wall of the housing away from the dust outlet 4123a, thereby further reducing the momentum loss of the airflow at the dust inlet 4122a and more effectively preventing dust and debris from accumulating in the dead corners of the dust box housing 410, further reducing the deposition of dust and debris. It can be understood that the specific value of the distance H can be set according to actual needs to achieve the best cleaning effect.

[0056] In some embodiments, the housing sidewall has a guide surface 4126 extending in a first direction, the guide surface 4126 being located in a second direction on the side of the housing sidewall away from the dust inlet 4122a, and the guide surface 4126 being located in a third direction on the side of the housing sidewall away from the dust outlet 4123a.

[0057] Thus, the arc-shaped guide surface 4126 reduces momentum loss during airflow, effectively preventing dust and debris residue. Simultaneously, it controls the airflow direction, guiding it towards the dust outlet 4123a, allowing dust and debris to flow smoothly out. It is understood that the bending radius and other dimensions of the guide surface 4126 can be set as needed to meet different airflow requirements.

[0058] In one specific embodiment, the lower shell 412 of the dust box has a cubic structure. The side wall of the shell includes a first side wall 4122, a second side wall 4123, a third side wall 4124 and a fourth side wall 4125 that are arranged sequentially and connected end to end along the circumference of the receiving cavity 412a. The first side wall 4122 and the third side wall 4124 are spaced apart in a second direction, and the second side wall 4123 and the fourth side wall 4125 are spaced apart in a third direction.

[0059] Furthermore, the first sidewall 4122 has a rectangular dust inlet 4122a near the fourth sidewall 4125, and the second sidewall 4123 has a rectangular dust outlet 4123a. The length direction of the dust inlet 4122a is parallel to the second direction, and the width direction of the dust inlet 4122a is parallel to the first direction. The distance H between the edge of the dust inlet 4122a near the fourth sidewall 4125 and the fourth sidewall 4125 satisfies: 0 < H ≤ 1 mm. The connection between the third sidewall 4124 and the fourth sidewall 4125 forms a guide surface 4126 extending along the first direction.

[0060] Please see Figure 6 In some embodiments, sufficient space is provided by reducing the distance between the edge of the dust inlet 4122a and the sidewall of the housing in the third direction away from the dust outlet 4123a. This allows for the protrusion of multiple reinforcing ribs 4125b along the second direction on the sidewall of the housing near the dust inlet 4122a in the third direction, with the reinforcing ribs 4125b located on the sidewall of the housing facing away from the receiving cavity 412a. The multiple reinforcing ribs 4125b are staggered, thereby defining and forming multiple reinforcing cavities 4125a spaced apart in a plane perpendicular to the third direction. The formation of the reinforcing cavities 4125a improves the structural strength of the housing sidewall, preventing deformation of the lower dust box 412 under high negative pressure, thus ensuring a good sealing effect.

[0061] In one specific embodiment, reinforcing ribs 4125b are disposed on the side of the fourth sidewall 4125 facing away from the receiving cavity 412a. Multiple reinforcing ribs 4125b form a honeycomb structure, and at least part of the reinforcing cavity 4125a has a hexagonal cross-section perpendicular to the third direction. It is understood that the shape of the reinforcing ribs 4125b is not limited to this. In other embodiments, the reinforcing ribs 4125b can be straight ribs, Z-shaped ribs, T-shaped ribs, grid ribs, or corrugated ribs. The shape of each reinforcing rib 4125b can be the same or different, thereby forming reinforcing cavities 4125a of different shapes to meet different structural needs.

[0062] In some embodiments, the side wall of the dust box lower shell 412 is provided with two lower shell mounting grooves 4125c on the side away from the bottom wall 4121. The two lower shell mounting grooves 4125c are arranged adjacent to the reinforcing cavity 4125a in a first direction, and the two lower shell mounting grooves 4125c are spaced apart along a second direction for mating with the upper shell 414 of the dust box. It is understood that the number of lower shell mounting grooves 4125c is not limited to this, and can be set as needed to meet different mating requirements. Specifically, in one embodiment, the lower shell mounting grooves 4125c are provided on the fourth side wall 4125.

[0063] Please combine Figure 2 , Figure 3 as well as Figure 7 As shown, the upper shell 414 of the dust box has a hollow rectangular frame structure. The upper shell 414 of the dust box is fixedly connected to the end of the lower shell 412 of the dust box away from the bottom wall 4121 of the shell by welding, bonding or other means.

[0064] Furthermore, the upper dustbin shell 414 has two rotating shafts 4141 at one end in the third direction. The two rotating shafts 4141 are arranged at a second interval, and each rotating shaft 4141 extends in the second direction. Each rotating shaft 4141 is respectively confined in a lower shell mounting groove 4125c of a lower dustbin shell 412. The upper dustbin cover 434 has two first snap-fit ​​parts 4143 at the other end in the third direction. The two first snap-fit ​​parts 4143 are arranged at intervals in the second direction. It can be understood that the number of rotating shafts 4141 and first snap-fit ​​parts 4143 is not limited and can be set as needed to meet different fitting requirements.

[0065] Thus, one end of the dust box cover 430 can be rotatably connected to the upper dust box shell 414 via the rotating shaft 4141, and the other end of the dust box cover 430 can be limited to the upper dust box shell 414 via the first snap-fit ​​part 4143. Since the rotating shaft 4141 is limited to the lower shell mounting groove 4125c, the rotating shaft 4141 is supported on the side of the lower dust box shell 412 where the reinforcing rib 4125b is provided. The reinforcing rib 4125b can support the rotating shaft 4141 and prevent the rotating shaft 4141 from shifting, which would affect the connection stability and opening and closing smoothness of the dust box shell 410 and the dust box cover 430.

[0066] Please see Figure 2 , Figures 8 to 10 As shown, the dust box cover 430 is generally a hollow shell structure, including a lower dust box cover 432 and an upper dust box cover 434.

[0067] The dust box lower cover 432 is roughly rectangular hollow frame structure. The dust box lower cover 432 has a connection hole at one end in the third direction that matches the rotating shaft 4141 of the dust box upper shell 414. The dust box lower cover 432 is rotatably connected to the rotating shaft 4141 through the connection hole, thereby realizing the rotatable connection between the dust box cover 430 and the dust box shell 410.

[0068] The dustbin lower cover 432 has a groove 432a and two second latching parts at one end in the third direction. The two second latching parts are located on opposite sides of the groove 432a in the second direction, and each second latching part is engaged with a first latching part 4143 of the dustbin upper shell 414. The dustbin lower cover 432 also has a dustbin spring clip 4321 on one side in the third direction. The dustbin spring clip 4321 is used to engage with the main body 200 so that the dustbin structure 400 is fixed relative to the main body 200.

[0069] The dust box cover 434 has a rectangular flat structure. The dust box cover 434 is fixedly connected to the dust box lower cover 432 on one side in the first direction by welding, bonding or other methods. The dust box cover 434 is provided with a dust box handle 4341, which allows the user to install and remove the dust box structure 400.

[0070] Thus, one end of the dustbin cover 430 is rotatably connected to one end of the dustbin housing 410 via a rotating shaft 4141, and the other end of the dustbin cover 430 is detachably engaged with the first snap-fit ​​portion 4143 of the dustbin housing 410 via a second snap-fit ​​portion. The user can apply force to the dustbin cover 430 through the groove 432a, causing it to rotate relative to the dustbin housing 410 to open or close, thereby removing or securing the filter assembly 450. It is understood that the engagement method between the dustbin cover 430 and the dustbin housing 410 is not limited to this and can be configured as needed to meet different installation requirements.

[0071] Please combine Figure 1 , Figure 11 as well as Figure 12 As shown, the main body 200 is provided with a sensing unit 210, and the filter assembly 450 is provided with a sensing unit 456. The sensing unit 210 is used to identify the sensing unit 456 and issue an alert signal. The alert signal includes, but is not limited to, at least one of light and sound.

[0072] Thus, when the sensing unit 210 detects the sensed unit 456, it indicates that both the dustbin structure 400 and the filter assembly 450 are installed on the main body 200, and the cleaning device 1000 can perform cleaning work normally. When the sensing unit 210 does not detect the sensed unit 456, it indicates that the dustbin structure 400 is not installed on the main body 200 or the filter assembly 450 is not installed on the dustbin structure 400. At this time, the sensing unit 210 can issue a reminder signal to remind the user to install the filter assembly 450 or the dustbin structure 400 in time, thereby realizing the presence detection of the filter assembly 450 and preventing the cleaning device 1000 from being used without the dustbin structure 400 or the filter assembly 450 installed, thereby preventing dust and debris in the dustbin structure 400 from entering the main body 200 and causing damage to the components inside the main body 200.

[0073] In some embodiments, when the filter assembly 450 is mounted on the main body 200 via the dust box structure 400, the sensing unit 210 and the sensed unit 456 are arranged adjacent to each other, thus placing the sensed unit 456 within the recognition range of the sensing unit 210, and the sensing unit 210 can recognize the sensed unit 456. It is understood that the distance and relative positional relationship between the sensing unit 210 and the sensed unit 456 are not limited and can be configured as needed to meet different recognition requirements.

[0074] In some embodiments, the sensing unit 210 includes a Hall element, and the sensed unit 456 includes a magnet. The principle of the Hall element in identifying a magnet is based on the Hall effect, the core of which is to detect the presence of a magnet by detecting voltage changes caused by a magnetic field. Specifically, in one embodiment, the sensing unit 210 includes a switch-type Hall element, which can determine the presence of a magnet by detecting the magnetic field strength. It is understood that the identification of the sensing unit 210 and the sensed unit 456 is not limited to this and can be configured as needed to meet different identification requirements.

[0075] Specifically, in some embodiments, the filter assembly 450 is detachably located between the dust box housing 410 and the dust box cover 430. Therefore, the filter assembly 450 can be disassembled separately, thereby enabling individual cleaning and replacement of the filter assembly 450, which reduces the cost of consumables.

[0076] The filter assembly 450 includes a filter support 452 and a filter body 454. The filter support 452 has a rectangular hollow frame structure, including a support bottom wall 4521 and support side walls 4523 surrounding the support bottom wall 4521 in the circumferential direction. The support bottom wall 4521 has a communication port 4521a for connecting to the receiving cavity 412a of the dust box housing 410. The filter body 454 is formed of HEPA (High-Efficiency Particulate Air) filter paper. The filter body 454 has a cubic structure and is installed in the filter support 452. The filter body 454 is connected to the receiving cavity 412a through the communication port 4521a.

[0077] Furthermore, the bracket sidewall 4523 has an outwardly protruding bracket mounting groove 4523a on the third-direction upward side. The open end of the bracket mounting groove 4523a communicates with the inner surface of the bracket sidewall 4523, and the sensing unit 210 or the sensed unit 456 is at least partially housed within the bracket mounting groove 4523a. It is understood that the installation method and position of the sensing unit 210 or the sensed unit 456 are not limited and can be configured as needed to meet different requirements.

[0078] In some embodiments, the filter assembly 450 further includes a seal that contacts the dust box housing 410 and / or the dust box cover 430. The seal is used to close the gap between the filter assembly 450 and the dust box housing 410 or the dust box cover 430 to prevent dust from flowing out of the gap between the filter assembly 450 and the dust box housing 410 or the dust box cover 430. Specifically, the seal may be formed of a material that can undergo elastic deformation, such as rubber or foam, thereby achieving a good sealing effect.

[0079] In one specific embodiment, the filter assembly 450 includes a first seal 458 and a second seal 459. The first seal 458 is disposed on the lower surface of the support bottom wall 4521 and surrounds the communication opening 4521a circumferentially, while the second seal 459 surrounds the outer side of the support side wall 4523 circumferentially. Thus, when the filter assembly 450 is installed between the dust box housing 410 and the dust box cover 430, the first seal 458 abuts against the upper dust box housing 414, and the second seal 459 abuts against the lower dust box cover 432.

[0080] The aforementioned dust box structure 400, on the one hand, improves the dust box housing 410 by eliminating the four corners of the airflow inside the dust box housing 410, allowing the airflow generated by the base station to flow smoothly through the interior of the dust box housing 410 to remove dust and debris, significantly reducing dust and debris residue and improving the cleaning effect of the dust box structure 400. On the other hand, by detecting the presence of the filter assembly 450, it can automatically determine whether the filter assembly 450 is installed, thereby promptly reminding the user to install the filter assembly 450 and preventing the cleaning device 1000 from being damaged by operating without the filter assembly 450 or the dust box structure 400 installed.

[0081] 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.

[0082] 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.
