Dust box components and cleaning equipment

Abstract

This utility model relates to a dustbin assembly and a cleaning device, comprising a housing with an air inlet and an air outlet. A mounting base containing a filter is disposed within the housing, allowing suction airflow to be drawn into the housing through the air inlet, pass through the filter, and exit through the air outlet. A baffle is rotatably mounted on the inner side of the air inlet, and this baffle can rotate under the pressure difference between the inner and outer sides of the housing to open or close the air inlet. The mounting base and the filter are spaced apart from the baffle, allowing the baffle to rotate to fully open the air inlet without obstruction from the mounting base and the filter. Due to the gap between the baffle, the mounting base, and the filter, during the process of the baffle flipping up to open the air inlet, the filter and the mounting base do not obstruct the flipping of the baffle or cause any other form of interference, allowing the air inlet to be fully opened without obstruction of the suction airflow, thereby improving suction efficiency.

Description

Technical Field

[0001] This utility model relates to the field of household appliances, specifically to a dustbin assembly. Furthermore, it also relates to a cleaning device including this dustbin assembly. Background Technology

[0002] Various intelligent cleaning devices, such as robotic vacuum cleaners and cordless vacuum cleaners, have become indispensable automated cleaning tools in modern homes and offices. Among these devices, the dustbin assembly is one of the core components, specifically designed to hold sucked-in debris and filter the exhaust air. As a component that directly filters the sucked-in air, the design of the dustbin directly affects the overall cleaning efficiency, filtration performance, and user experience of the device.

[0003] When the dust box is working, the equipment fan generates negative pressure. Dust-laden air from outside is drawn into the dust box through the air inlet under the pressure difference. Large particles of garbage are intercepted and settle at the bottom of the dust box, while the airflow passes through the filter set inside the dust box. Tiny dust particles are blocked by the filter, and the clean air is finally discharged from the air outlet and returned to the environment.

[0004] In the design of cleaning equipment, especially robotic vacuum cleaners, dustbin designers need to ensure that the dustbin can not only suck up dust but also common lightweight debris such as hair and lint. Existing dustbin components generally have flawed air inlets, causing debris to accumulate at the inlet during suction. This prevents the full utilization of the dustbin's collection space, obstructs airflow, and ultimately reduces the cleaning efficiency of the equipment.

[0005] Therefore, how to provide a dustbin assembly that allows for smooth airflow and is less prone to clogging is an important technical challenge currently faced by those skilled in the art. Utility Model Content

[0006] The purpose of this invention is to overcome the problem in the existing technology of how to provide a dust box assembly with smooth airflow and less clogging by garbage.

[0007] The inventor of this utility model, after conducting in-depth analysis of the technical dilemma of the difficulty in balancing the air duct and the filter, creatively discovered that the reason for the abnormal increase in air resistance is that the baffle of the air inlet interferes with the filter in the dust box when it is opened, which prevents the air inlet from being fully opened. This not only reduces the air intake volume, but also increases the risk of garbage accumulating in the air inlet and causing blockage.

[0008] Therefore, to achieve the above objectives, it is necessary to solve the interference problem between the filter element and the baffle of the air inlet. To this end, the first aspect of this utility model provides a dust box assembly, which includes a box body with an air inlet and an air outlet that are interconnected. The box body includes a mounting base, in which a filter element is disposed. Suction airflow enters the box body through the air inlet, passes through the filter element, and exits the box body through the air outlet. A baffle is disposed on the inner side of the air inlet, which is rotatably fixed within the box body and is used to rotate to open or close the air inlet. The baffle has an open position, in which the bottom end of the baffle is higher than or flush with the top end of the air inlet.

[0009] In the technical solution proposed in this utility model, the dust box assembly is installed in the cleaning equipment. The air outlet is connected to the fan in the cleaning equipment, and the air inlet is exposed to the outside. When the fan of the cleaning equipment creates negative pressure and suction, negative pressure can be formed in the box through the air outlet, thereby creating a suction airflow between the air inlet and the air outlet, which sucks the dust and debris on the cleaning surface into the box. The suction airflow is filtered by the filter element, thereby adsorbing dust and preventing debris from entering the air duct of the cleaning equipment from the air outlet and causing malfunctions. When the cleaning equipment generates negative pressure to produce suction airflow, the movable end of the baffle at the air inlet can be driven to rotate to fully open under the negative pressure in the dust box. During the process of the baffle flipping to the open position to open the air inlet, the filter element and the mounting base will not obstruct the flipping of the baffle or interfere in any other way, so that the baffle 111 can rotate to its lowest position higher than or flush with the top of the air inlet 11, and the suction airflow is unobstructed, improving the suction efficiency.

[0010] In some embodiments, the mounting base and filter are disposed within the housing on the side away from the air inlet to prevent the baffle from contacting the mounting base and / or filter during rotation.

[0011] In some embodiments, the opening angle α of the baffle relative to the air inlet is 70° to 150°.

[0012] In some embodiments, the filter element has a first end and a second end that are far apart from each other, wherein the first end is closer to the air inlet than the second end, and the length of the air outlet is less than or equal to the distance between the first end and the second end in the horizontal direction, and the air outlet is located at a position corresponding to the second end of the filter element.

[0013] In some embodiments, with the second end of the filter element as the starting point, the length of the air outlet in the horizontal direction is 1 / 3 to 1 / 4 of the length of the box body.

[0014] In some embodiments, the box body is also provided with a dust collection port, which can be closed to form a dust collection air duct between the air inlet and the air outlet, and can be opened to discharge the garbage deposited in the box body through the dust collection port.

[0015] In some embodiments, the bottom of the box includes a first slope and a second slope. One end of the first slope faces the air inlet and extends downward at an angle to one end of the second slope. Along the direction from the air inlet to the dust collection port, the second slope extends upward at an angle or parallel to the horizontal plane to form the lowest point of the bottom of the box at the junction of the first slope and the second slope.

[0016] In some embodiments, the second slope segment includes a second slope segment a and a second slope segment b connected to each other. The second slope segment a and the second slope segment b are arranged sequentially along the direction from the air inlet to the dust collection outlet. The second slope segment a extends upward at an angle along the direction from the air inlet to the dust collection outlet, and the second slope segment b is parallel to the horizontal plane and extends to the bottom of the dust collection outlet.

[0017] In some embodiments, the filter element includes a filter cartridge with a thickness of 1cm-2cm.

[0018] In some embodiments, a vibrating element is provided inside the housing, and the vibrating element is configured to be close to or in contact with the filter element so as to vibrate the filter element.

[0019] In some embodiments, the mounting base is provided with a mounting groove, and the vibrating element is fixedly disposed in the mounting groove so as to vibrate the filter element.

[0020] A second aspect of this invention also provides a cleaning device, which includes the aforementioned dust box assembly.

[0021] In the technical solution provided by this utility model, by clearly setting the mounting base and filter element and the baffle, sufficient and interference-free space is reserved for the rotation of the baffle, ensuring that the baffle can rotate to the fully open state in response to the airflow, thereby reducing the airflow resistance encountered when the suction airflow enters the box and improving the overall suction efficiency of the cleaning equipment.

[0030] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification.

[0031] To achieve the above objectives, the first aspect of this utility model provides a dustbin assembly, such as... Figures 1-5 As shown, it includes a box body 1, on which an air inlet 11 and an air outlet 12 are provided that are interconnected. The box body 1 includes a mounting base 14, in which a filter element 2 is provided. The airflow is drawn into the box body 1 through the air inlet 11, passes through the filter element 2, and flows out of the box body 1 through the air outlet 12. A baffle 111 is provided on the inner side of the air inlet 11. The baffle 111 is rotatably fixed in the box body 1 and is used to rotate to open or close the air inlet 11. The baffle 111 has an open position. In the open position, the bottom end of the baffle 111 is higher than or flush with the top end of the air inlet.

[0032] In the technical solution proposed by this utility model, the dust box assembly is installed in the cleaning equipment. The air outlet 12 is connected to the fan in the cleaning equipment, and the air inlet 11 is exposed to the outside. When the fan of the cleaning equipment creates negative pressure and suctions, negative pressure can be formed inside the box 1 through the air outlet 12, thereby forming a suction airflow between the air inlet 11 and the air outlet 12, which sucks the dust and debris on the cleaning surface into the box 1. The suction airflow is filtered by the filter element 2, thereby adsorbing dust and preventing debris from entering the air duct of the cleaning equipment from the air outlet 12 and causing malfunctions. When the cleaning equipment generates negative pressure to produce suction airflow, the movable end of the baffle 111 at the air inlet 11 can be driven to rotate to the open position under the negative pressure inside the dust box, so as to fully open the air inlet 11. During the process of flipping the baffle 111 to the open position to open the air inlet, the filter element 2 and the mounting base 14 will not obstruct or interfere with the flipping of the baffle 111, so that the baffle 111 can rotate to its lowest position higher than or flush with the top of the air inlet 11, and the suction airflow is unobstructed, thus improving the suction efficiency.

[0033] The aforementioned open position of the baffle 111 refers to the position where, under the negative pressure inside the housing 1, the baffle 111 is driven to fully open the air inlet 11, thereby preventing the baffle 111 from forming an obstruction in the suction duct inside the housing 1. That is, when the baffle 111 is rotated to the open position, the bottom end of the baffle 111 is higher than or flush with the top end of the air inlet 11.

[0034] In the above-described arrangement of the baffle 111, mounting base 14, and filter element 2, any position can be used to prevent the baffle 111 from contacting the mounting base 14 and filter element 2 when it moves to the open position. For example, the mounting base 14 and filter element 2 can be positioned at intervals from the rotation path of the baffle 111, so that the mounting base 14 and baffle 2 do not obstruct the rotation path of the baffle 111. Furthermore, by adjusting the thickness of the filter element 2 and mounting base 14 in the vertical direction, the baffle 111 can be positioned so that its lowest point after rotation is higher than or flush with the top of the air inlet 11 before contacting and abutting against the mounting base 14 and filter element 2.

[0035] The dust box assembly provided by this utility model is installed in a cleaning device to filter the suction airflow generated by the cleaning device. Therefore, without changing the positional relationship between the baffle 111, the mounting base 14, and the filter element 2, the shape of the box body 1 can be set to any shape that can adapt to the cleaning device. Those skilled in the art can also adjust the shape design of the box body 1 according to the actual shape of the cleaning device to obtain an aesthetically pleasing cleaning device.

[0036] The container 1 can be made of any material that can maintain the required structural strength. Under this premise, the container 1 can be made of transparent or translucent material so that the user can intuitively observe the amount of waste inside the container 1.

[0037] The aforementioned waste includes dust on the cleaned surface and lightweight foreign objects that can be drawn into the housing 1 by the suction airflow, such as shredded paper, hair, and debris.

[0038] Provided that an air duct can be formed between the air inlet 11 and the air outlet 12 and the housing 1, the air inlet 11 and the air outlet 12 can be positioned at any location on the housing 1, for example, on two opposite sides of the housing 1. Technicians can determine the positions of the air inlet 11 and the air outlet 12 based on the structure of the cleaning equipment, while ensuring the air duct between them is maintained. Figure 1 As shown, the air inlet 11 and the air outlet 12 may not be arranged opposite each other. Instead, the air outlet 12 may be arranged on both sides of the side opposite to the air inlet 11, so that the air can pass through the air outlet.

[0039] The mounting base 14 is used to define the position of the filter element 2 inside the housing 1. It can be integrally formed with the housing 1 or separately disposed inside the housing 1. The mounting base 14 is used to position the filter element 2 between the air inlet 11 and the air outlet 12, thereby ensuring that the suction airflow entering the housing 1 from the air inlet 11 can exit the housing 1 through the air outlet 12 only after passing through the filter element 2. The mounting base 14 can be formed in any shape that can confine the filter element 2 within the housing 1, for example, it can be formed as a bracket adapted to the shape of the filter element 2, such as... Figure 4 As shown, or multiple grooves that partially adapt to the filter element 2 are formed on the inner surface of the box body 1, so that when the filter element 2 is placed inside the box body 1, the various parts on the filter element 2 cooperate with the above-mentioned multiple grooves, thereby limiting the filter element 2.

[0040] The filter element 2 can be any component capable of filtering the airflow passing through it, such as a filter screen, a HEPA filter, or an activated carbon filter. A HEPA filter refers to a High-Efficiency Particulate Air filter, also known as "HEPA" in the relevant field. The filter element 2 can also be composed of one or more of the aforementioned filter components. All of the above-mentioned filter components are existing components with filtration functions in the prior art. Depending on the specific location and function of the dust box assembly in the cleaning equipment, technicians can select different filter elements 2 to meet corresponding needs.

[0041] The baffle 111 can be rotatably fixed inside the housing 1 in any manner, allowing it to be rotated upwards by negative pressure, thereby fully opening the air inlet 11. For example, the top end of the baffle 111 can be rotatably mounted to the inner surface of the housing 1 above the air inlet 11 using a pivot structure or hinge structure. When using a pivot structure, two symmetrical pivots are formed at each end of the top of the baffle 111. Correspondingly, two shaft grooves matching the pivots are provided on the inner surface of the housing 1 above the air inlet 11. These shaft grooves have semi-open recesses with their openings facing the mounting path of the baffle. During assembly, the pivots on both sides of the baffle 111 are pressed into and engaged with the shaft grooves on the inner wall of the housing 1. The pivots are limited by the shaft grooves, allowing the baffle 111 to rotate freely about the central axis of the pivot, thereby opening and closing the air inlet.

[0042] In some embodiments, the filter element 2 can be configured as a filter cartridge integrating multiple different types of filter elements. From upstream to downstream of the airflow, the filter cartridge may sequentially include a pre-filter layer made of sponge or similar material, a high-efficiency filter layer made of HEPA filter, and an odor-absorbing layer made of activated carbon. These three elements are integrated within a single frame, facilitating easy disassembly and replacement by the user.

[0043] In some embodiments, a specific limiting structure may be provided on the baffle 111 or the inner surface of the box 1 to limit the opening angle a of the baffle 111. For example, a limiting protrusion may be provided on the inner surface of the box 1. When the baffle 111 is flipped to a predetermined angle, the baffle 111 abuts against the limiting protrusion, thereby limiting the opening angle a of the baffle 111 to a predetermined size through the limiting protrusion.

[0044] In some embodiments, the portion of the housing 1 above the air inlet 11 may be angled to limit the baffle 111 when it is flipped upwards, thereby limiting the opening angle α of the baffle 111. When the baffle 111 is flipped upwards to a predetermined angle, the baffle 111 fits against the housing 1 at the angle and is thus limited by the housing 1. This limits the opening angle α of the baffle 111 to a predetermined size.

[0045] After the cleaning equipment finishes suctioning, there is no more suction airflow in the dust box. The baffle 111 falls under its own weight, switching the air inlet 11 from the open state to the closed state. However, if the baffle 111 rotates at too large an angle, it may be in a vertical or almost vertical position relative to the horizontal plane. In this case, the weight of the baffle 111 is insufficient to provide enough force to rotate it downwards, making it difficult for the baffle 111 to fall and keeping the air inlet 11 open. By setting a limiting structure, the baffle 111 can be prevented from rotating to the aforementioned angle, thus preventing it from rotating to a position where it cannot fall under its own weight and preventing the baffle 111 from failing to close the air inlet 11.

[0046] In some embodiments, the mounting base 14 and the filter element 2 are disposed inside the housing 1 on the side away from the air inlet 11 to prevent the baffle 111 from contacting the mounting base 14 and / or the filter element 2 during rotation.

[0047] In this embodiment, the mounting base 14 and the filter element 2 housed therein are integrally positioned outside the rotation path. More specifically, this arrangement ensures that when the baffle 111 is in its maximum open position, there is a predetermined gap between any part of its surface and any part of the mounting base 14 or the filter element 2, preventing the baffle 111 from contacting the mounting base 14 and / or the filter element 2. This completely contactless design eliminates the possibility of the baffle 111 colliding, scratching, or getting stuck with any component during opening and closing, ensuring smooth and reliable movement in response to airflow or gravity. Simultaneously, the absence of contact friction during movement avoids long-term wear on the baffle 111 or the filter element 2 frame, and also eliminates operating noise that may be caused by component scratching.

[0048] In some embodiments, such as Figure 4 As shown, the size of the baffle 111 is set to be larger than the size of the air inlet 11 so that it can be rotated to completely close the air inlet 11.

[0049] By setting a baffle 111 whose size is completely larger than that of the air inlet 11, the air inlet 11 can be completely blocked when the baffle 111 is rotated to close the air inlet 11, so as to completely isolate the air inlet 11 from the external environment and prevent dust and foreign objects collected inside the box 1 from falling into the external environment from the air inlet 11 as the cleaning equipment moves.

[0050] In some embodiments, such as Figure 5 As shown, the opening angle α of the baffle 111 relative to the air inlet 11 is 70° to 150°.

[0051] After testing, the inventors found that when the opening angle α is less than 70°, the projected area of ​​the baffle 111 on the air inlet 11 cross-section is large when it is open, which still obstructs the suction airflow and reduces the airflow volume and velocity. When the opening angle α is greater than 70°, the impact on the suction airflow is smaller, and the airflow velocity and volume can be guaranteed to meet the required standards. When the opening angle α exceeds 150°, the baffle 111 is nearly perpendicular to the horizontal plane. In this position, the baffle 111's own weight is insufficient to generate a sufficient rotational torque, which may prevent it from automatically falling back to close the air inlet 11 after cleaning, thus posing a risk of waste leakage. However, when the opening angle is less than 150°, the baffle 111 can automatically fall back and close the air inlet 11 after cleaning, relying on its own weight.

[0052] To achieve an opening angle α greater than or equal to 70°, the positions of the mounting base 14 and the filter element 2 within the housing 1 need to be adjusted to prevent interference between the baffle 111 and the mounting base 14 and the filter element 2 when the baffle 111 is rotated to a rotation angle greater than 70°. At the same time, the weight of the baffle 111 should be reasonably set according to the negative pressure generated by the fan of the cleaning equipment to prevent the negative pressure inside the housing 1 from failing to drive the baffle 111 to rotate to a rotation angle of 70°.

[0053] To achieve a flipping angle of less than or equal to 150 degrees, the aforementioned limiting structure can be set to limit the baffle 111 when it flips to 150 degrees, preventing the baffle 111 from flipping further upward.

[0054] In some embodiments, such as Figure 2 , Figure 4 and Figure 5 As shown, the air inlet 11 on the housing 1 can be set to be inclined to the horizontal plane. Specifically, in the flow direction, the top of the air inlet 11 is further back than the bottom, thereby forming an air inlet section inclined towards the ground at the air inlet 11.

[0055] By tilting the air inlet 11, the air inlet 11 can face the surface to be cleaned, which makes the suction force of the airflow on the surface to be cleaned stronger when the cleaning equipment is vacuuming, thereby improving the cleaning efficiency of the cleaning equipment.

[0056] Meanwhile, when the air inlet 11 is closed by the baffle 111, the baffle 111 falls onto the inclined air inlet 11. At this time, the weight of the baffle 111 itself presses it down onto the air inlet 111, thus covering the air inlet 111 and completely closing it. When the air inlet 11 is set perpendicular to the ground, when the baffle 111 falls back to close the air inlet 111, it may sway back and forth with the movement of the cleaning equipment at its bottom position, which may cause the air inlet 111 to not close completely, and dust and debris in the box 1 to leak out. However, when the baffle 111 falls back and presses on the inclined air inlet 11, due to the effect of the baffle 111's own weight, the baffle 111 is not easily affected by the movement of the cleaning equipment or other external forces to release the closed state of the air inlet 111, thus ensuring that dust and debris in the box 1 are not easily leaked into the external environment.

[0057] It is understood that the specific tilt angle of the air inlet 11 can be adaptively adjusted according to factors such as the chassis height and roller brush design of the entire cleaning equipment, and this application does not impose a specific limitation on it. Those skilled in the art will understand that, without conflicting with other structures or functions of this utility model, setting the air inlet 11 to any tilt angle that helps improve cleaning efficiency and assists the baffle 111 in maintaining its position on the air inlet 11 should fall within the scope of this embodiment.

[0058] In some embodiments, such as Figure 1 , Figure 2 and Figure 4 As shown, the filter element 2 has a first end 21 and a second end 22 that are far apart from each other. The first end 21 is closer to the air inlet 11 than the second end 22. In the horizontal direction, the length of the air outlet 12 is less than or equal to the distance between the first end 21 and the second end 22. The air outlet 12 is located at a position corresponding to the second end 22.

[0059] In the above arrangement, the size of the air outlet 12 along the airflow direction is smaller than the overall size of the filter element 2 in the same direction. Furthermore, the air outlet 12 is located on the housing 1, and its position corresponds to the second end of the filter element 2, which serves as the air outlet.

[0060] The air outlet 12 serves as the airflow outlet and is the negative pressure concentration area within the entire dust box assembly. Positioning it at the second end of the filter element 2 ensures that the path of the suction airflow must cover most of the area of ​​the filter element 2 from the first end to the second end. This effectively avoids the problem of uneven utilization of the filter element 2 caused by the airflow only passing near the first end of the filter element 2.

[0061] This structure ensures that the airflow is more evenly distributed in the effective filtration area of ​​the filter element 2, improves the overall utilization rate of the filter element 2, delays the performance degradation caused by local blockage, and extends its service life.

[0062] In some embodiments, with the second end 22 of the filter element as the starting point, the length of the air outlet 12 in the horizontal direction is 1 / 4 to 1 / 3 of the length of the box body 1.

[0063] The air outlet 12 is located at the rear of the housing 1, specifically, its starting position in the horizontal direction is roughly aligned with the second end 22 of the filter element 2. Since the air outlet 12 is the only outlet with the most concentrated negative pressure inside the housing 1, and is located at the very end of the filter element 2, this forces the airflow to travel through most of the length of the filter element 2 before exiting. This ensures that the entire surface of the filter element 2 from the first end to the second end 22 is used evenly and fully, avoiding the waste of the front end being prematurely clogged while the rear end remains clean, thus extending the overall lifespan of the filter element. Simultaneously, this layout creates an airflow field inside the housing 1 that runs from the front air inlet 11 to the rear air outlet 12, penetrating the entire dust collection chamber. This actively transports the waste just sucked in from the air inlet 11 towards the depth and rear of the housing 1, effectively preventing all waste from accumulating in the area close to the air inlet 11. This not only prevents blockage at the inlet due to waste accumulation but also allows for more rational use of the entire dust collection chamber's storage space.

[0064] In some embodiments, such as Figure 4 and Figure 5 As shown, the box body 1 is also provided with a dust collection port 13. The dust collection port 13 can be closed to form a dust collection air duct between the air inlet 11 and the air outlet 12, and can be opened to discharge the garbage deposited in the box body 1 through the dust collection port 13.

[0065] The dust collection port 13 is provided with a sealing structure that can be selectively opened or closed in different working modes. The sealing structure can be set in a variety of known forms in the art, such as a snap-on cover, a magnetically adsorbed cover, a plug based on an elastomeric interference fit, or a linkage opening door driven by an external device.

[0066] When the cleaning equipment is operating normally and the debris on the surface to be cleaned is sucked into the dust box, the sealing structure of the dust collection port 13 is in the closed state, reliably sealing the dust collection port 13. At this time, a suction air duct is formed inside the box body 1, pointing from the air inlet 11 to the air outlet 12. The cleaning equipment's own fan operates, and the dusty air from outside is drawn in through the air inlet 11. After being filtered, the clean air is discharged through the air outlet 12, performing the normal floor cleaning task.

[0067] When the cleaning equipment collects dust, the sealing structure of the dust collection port 13 is opened, and the cleaning equipment connects to an external dust collection device through the dust collection port 13. This external dust collection device can be a base with automatic dust collection. The external dust collection device has a built-in device that can generate negative pressure, such as a suction fan. It generates negative pressure inside the dust box assembly through the dust collection port 13, at which time a suction air duct is formed inside the box 1, pointing from the air inlet 11 to the dust collection port 13. External air is drawn in through the air inlet 11, forming a suction airflow inside the box 1, which picks up the previously collected dust, hair, and other debris, and draws them into the external dust collection device through the dust collection port 13, thereby removing the debris collected in the box 1.

[0068] The power of the suction fan in the external dust collection device is matched to the dust collection requirements of the dust box. This ensures that, with both the air inlet 11 and outlet 12 connected to the box body 1, a sufficiently strong suction airflow is generated within the box body 1 to draw away debris through the dust collection port 13. Under negative pressure, the airflow preferentially follows the path of least resistance, primarily entering through the air inlet 11 with the largest flow area and directly impacting the position of highest negative pressure, i.e., the dust collection port 13. This creates a powerful purging effect inside the box body 1, sufficient to carry away all debris adhering to its inner walls and the surface of the filter element 2, thus achieving a highly efficient and reliable automatic dust collection function without the need for additional sealing of other air vents.

[0069] The dust collection port 13 allows for timely emptying of the dustbin 1, preventing the cleaning equipment from being unable to perform its cleaning function once the dustbin 1 is full. Furthermore, by directly connecting the dustbin 1 to an external dust collection device, the dustbin 1 can be cleaned quickly and conveniently without having to remove the dustbin assembly from the cleaning equipment for manual cleaning, thus improving the user experience of the dustbin assembly.

[0070] In some embodiments, such as Figure 4 and Figure 5 As shown, the dust collection port 13 can be disposed on the side of the box body 1, directly opposite the air inlet 11.

[0071] With the dust collection port 13 configured as described above, in modes requiring dust evacuation, when the dust collection port 13 is opened and connected to an external dust collection device, air can enter from the air inlet 11, forming a straight suction duct that runs through the interior of the housing 1 and directly leads to the dust collection port 13. Because this straight suction duct has no corners, it is less prone to creating dead angles where debris can get stuck. At the same time, the air resistance of the duct is lower than other types of ducts, resulting in higher suction efficiency.

[0072] In some embodiments, the sealing structure on the dust collection port 13 can be a manually operable snap-fit ​​structure. This sealing structure includes a sealing door and a snap-fit ​​mechanism. The sealing door is rotatably connected to the edge of the dust collection port 13 on the housing 1 via a hinge or pin. The snap-fit ​​mechanism includes a hook disposed on the free end of the sealing door and a retaining portion molded at a corresponding position on the housing 1. The retaining portion has a snap-fit ​​surface that matches the hook. To ensure sealing, an elastic sealing ring is provided on the inner edge of the sealing door.

[0073] When it is necessary to close the dust collection port 13, the user manually flips the sealing door to the closed position and presses it towards the housing 1. Under the pressure, the hook slides along the latch and temporarily passes over the latch using the elastic deformation of the material, then springs back and forms a secure engagement. In this locked state, the elastic sealing ring is moderately compressed to form an airtight seal, preventing air or dust leakage during vacuuming.

[0074] When it is necessary to empty the dust box, the user can use their fingers to pull the hook or the protrusions nearby to disengage the hook from the latch, thereby unlocking it. Then, the sealed door can be opened to dump or suck up the garbage.

[0075] This manual snap-lock sealing structure has a mature design, few parts, requires no additional power source, and has extremely high reliability and cost advantages, making it particularly suitable for cleaning equipment with high requirements for cost control.

[0076] In some embodiments, such as Figure 3 , Figure 4 and Figure 5 As shown, the bottom of the box 1 includes a first slope 15 and a second slope 16. One end of the first slope 15 faces the air inlet 11 and extends downward at an angle to one end of the second slope 16. Along the direction from the air inlet to the dust collection port, the second slope 16 extends upward at an angle or parallel to the horizontal plane to form the lowest point of the bottom of the box 1 at the connection between the first slope 15 and the second slope 16.

[0077] With the above configuration, a low-lying area consisting of the first slope section 15 and the second slope section 16 can be formed at the bottom of the box 1. This low-lying area serves as the lowest point inside the box 1 and can collect the garbage that enters the box 1.

[0078] When the cleaning equipment is working, the dust, debris and other garbage sucked in enter the box 1. Under the action of gravity and the vibration generated by the operation of the equipment itself, they will naturally slide down along the first slope 15 and settle and accumulate in the aforementioned low-lying area away from the air inlet 11. This causes the garbage to accumulate in the low-lying area away from the air inlet 11, which greatly reduces the risk that the garbage in the box 1 will accidentally fall from the air inlet 11 due to its proximity to the baffle 111 when the equipment stops, is bumped or lifted, thus improving the reliability of garbage storage.

[0079] Furthermore, when used in conjunction with an external dust collection device that has an automatic dust collection function, the low-lying area concentrates the garbage at one point, allowing the external dust collection device to remove all the garbage more quickly, thereby improving the suction efficiency of the external dust collection device.

[0080] In some embodiments, the second slope 16 includes a second slope a segment and a second slope b segment connected to each other. The second slope a segment and the second slope b segment are arranged sequentially along the direction from the air inlet 11 to the dust collection port 13. The second slope a segment extends obliquely upward along the direction from the air inlet 11 to the dust collection port 13, and the second slope b segment 162 is parallel to the horizontal plane and extends to the bottom end of the dust collection port 13.

[0081] In this embodiment, the second slope section 16 is not a single inclined plane, but rather a smooth connection of two parts: second slope section a and second slope section b. These two sections are arranged sequentially from the air inlet 11 to the dust collection port 13. The upward inclination of the second slope section a, combined with the downward inclination of the first slope section 15, forms a deeper and more defined depression at their junction. This area, as the main waste settling zone, effectively collects the inhaled waste and reliably confines it away from the air inlet 11, preventing waste backflow. Simultaneously, the second slope section a gradually rises to approximately the same height as the bottom of the dust collection port 13 and connects with the second slope section b, thus forming a flat and unobstructed waste discharge channel through the second slope section b.

[0082] In some embodiments, such as Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the container 1 also includes an upper cover 17 and a lower container. The upper cover 17 is operably connected to the lower container to expose the space inside the container 1. The lower container constitutes the main space for containing waste, while the upper cover 17 covers the top opening of the lower container, forming a completely closed structure of the container 1.

[0083] The upper cover 17 can be detachably connected to the lower box body in a variety of ways known to those skilled in the art. For example, one side of the upper cover 17 can be pivotally connected to the lower box body via a pivot or hinge; or the upper cover 17 can also be detachably connected to the lower box body via a structure such as a snap-fit, slide rail or magnetic attraction.

[0084] When filter element 2 becomes clogged due to prolonged use and requires cleaning or replacement, the user can easily expose the internal space of housing 1 by simply opening or removing the top cover 17 without using any tools. At this time, the filter element 2 installed inside is clearly visible, and the user can easily remove it and replace it with a new filter element.

[0085] In addition, this large opening design also provides users with the convenience of manually emptying the garbage. When large foreign objects that cannot be discharged through the dust collection port 13 are sucked into the box 1, or in the absence of external dust collection equipment, users can quickly empty the internal garbage by opening the top cover 17.

[0086] In some embodiments, such as Figure 2 , Figure 4 and Figure 5 As shown, a vibrating element 3 is provided inside the box 1. The vibrating element 3 is positioned close to or in contact with the filter element 2 so as to vibrate the filter element 2.

[0087] The vibrating element 3 is fixedly installed near the filter element 2. Specifically, the vibrating element 3 can be installed on the rigid frame of the filter element 2 or on the inner wall of the housing 1 adjacent to the filter element 2, so as to ensure that the mechanical vibration it generates can be efficiently transmitted to the filter element 2.

[0088] The vibrating element 3 can be any existing device capable of generating high-frequency mechanical vibration, such as a linear vibration motor, an electromagnetic vibrator, or a piezoelectric ceramic vibrator.

[0089] The vibrating element 3 can be set as one or more, and the appropriate position can be selected for installation according to the size of the filter element 2, the size of the vibrating element 3 and the installation space in the box 1, so as to ensure that the entire filter element 2 can be vibrated.

[0090] To power the vibrating element 3 inside the housing 1, a detachable electrical connection needs to be established between the housing 1 and the main unit of the cleaning equipment. In embodiments of this application, this electrical connection can take various forms, such as contact electrodes, wireless power supply, or sealed pluggable connectors. When contact electrodes are used, electrode plates connected to the vibrating element 3 are provided on the outer wall of the housing 1, and elastic electrodes, such as spring pins, are provided at corresponding positions within the compartment of the main unit housing the housing 1. When the housing 1 is installed in place, the elastic electrodes on the main unit automatically press against the electrode plates of the housing 1, thereby establishing a stable electrical path to power the vibrating element 3.

[0091] When the vibrating element 3 is activated, it generates mechanical vibration. This vibration is transmitted to the filter element 2 through direct contact or structural conduction, causing dust particles attached to the surface of the filter element 2's fiber media to be shaken off due to the inertial force generated by the vibration exceeding their own adhesion force. The dislodged dust settles back to the bottom dust collection area of ​​the housing 1 under the action of gravity.

[0092] The working process of the vibrating element 3 can be configured as follows: after the cleaning equipment completes a cleaning task, or when the system detects an increase in the air resistance of the dust box through a sensor, its internal central processing unit can issue a command to start the vibrating element 3. Alternatively, it can be configured as follows: after the control module in the cleaning equipment receives a user command, a signal is connected to the control module of the vibrating element 3 to control the operation of the vibrating element 3.

[0093] By setting up the vibrating element 3, the micro-dust on the filter element 2 can be actively and automatically treated, thereby restoring the airflow performance of the filter element 2, avoiding the increase in wind resistance caused by blockage, and also extending the cycle of manual cleaning and replacement of the filter element 2 by the user, reducing the user's operating costs and improving the user experience.

[0094] In some embodiments, such as Figure 4 and Figure 5 As shown, the mounting base 14 is provided with a mounting groove 141, and the vibrating element 3 is fixedly installed in the mounting groove 141 so as to vibrate the filter element 2.

[0095] Specifically, the mounting base 14, used to accommodate and fix the filter element 2, has an integrally formed mounting groove 141. The shape and size of the mounting groove 141 match the shape of the vibrating element 3 in the aforementioned embodiment. The vibrating element 3 is embedded in the mounting groove 141 and is firmly fixed in the groove by means of adhesive, snap-fit, or heat fusion.

[0096] The mounting slot 141 provides a clear mounting reference, ensuring that the vibrator 3 can be precisely installed in the optimal position during assembly. Furthermore, when the vibrator 3 is a device with a specific vibration direction, such as a linear vibrating motor, the mounting slot 141 can strictly limit its vibration direction, ensuring that it strikes perpendicularly to the surface of the filter element 2, thereby guaranteeing the best dust removal effect.

[0097] Furthermore, since the mounting base 14 is in direct contact with the filter element 2, the vibrating element 3 is directly fixed on the mounting base 14, thus creating the shortest and most direct vibration transmission path. This reduces the attenuation of vibration energy during transmission, allowing the vibrating element 3 to transmit energy to the filter element 2 more efficiently and improving the dust removal efficiency.

[0098] In some embodiments, the vibrating element 3 is fixedly installed in an external vibration device, such as a cleaning equipment base station equipped with the vibrating element 3, with its vibrating end extending out to abut against a pre-reserved mating structure on the housing 1 for power transmission to the external vibrating element 3, thereby vibrating and removing dust from the filter element 2.

[0099] The aforementioned mating structure can be configured as a through hole in the wall of the housing 1, with the through hole positioned directly opposite the frame of the filter element 2 installed inside the housing 1 or its nearby mounting base 14. Correspondingly, the vibrating end of the vibrating element 3 on the main unit can be configured as a vibrating arm or punch that can pass through the through hole. When the housing 1 is placed in contact with external vibration equipment, the vibrating end of the vibrating element 3 passes through the through hole and directly abuts against or approaches the filter element 2. The mechanical vibration generated by the vibrating element 3 is directly and efficiently transmitted to the filter element 2 through the vibrating end, causing it to vibrate, thereby reducing the distance of the vibration transmission path, reducing the transmission loss of vibration energy, and improving the efficiency of vibration dust removal.

[0100] The aforementioned mating structure can also be configured as a portion formed on the outer wall of the sealed box 1, corresponding to the vibrating end of the vibrating element 3. When the box 1 is placed in contact with an external vibration device, the vibrating end of the vibrating element 3 abuts against this mating portion, thereby indirectly transmitting the vibration to the filter element 2 inside the box 1 through the structure of the box 1, thus performing vibration dust removal on the filter element 2 while keeping the box 1 sealed.

[0101] In some embodiments, the filter element 2 includes a filter cartridge with a thickness of 1cm-2cm.

[0102] The filter element mentioned above refers to the part of filter element 2 used for filtering air. For example, when filter element 2 is a HEPA filter, the filter element refers to the part of the HEPA filter used for filtering air, excluding structures such as the filter frame.

[0103] In this application, to ensure unobstructed opening of the baffle 111, the installation positions of the mounting base 14 and the filter element 2 are adjusted compared to traditional designs, for example, they are moved further away from the air inlet 11. While this innovative layout perfectly solves the air resistance problem at the air inlet, it may also impose certain design constraints on the dimensions of the filter element 2 itself, especially its windward area. To compensate for the potential reduction in windward area due to the position adjustment and to ensure that the filter element 2 still has a sufficiently large dust holding capacity and a long service life, this embodiment has made compensatory optimizations to the thickness of the filter element 2. Specifically, the thickness of the filter element 2 is set to 1cm to 2cm.

[0104] The above thickness range represents a balanced interval that has been repeatedly tested and optimized. If the thickness is less than 1cm, the dust holding capacity of the filter element is limited. With a limited frontal area, it may quickly become clogged, leading to increased wind resistance and a shorter service life. If the thickness is greater than 2cm, although the dust holding capacity will increase further, the filter element itself will also significantly increase its obstruction to airflow. This will partially offset the low wind resistance advantage brought about by the baffle being fully open, affecting the overall energy efficiency of the machine.

[0105] Therefore, by setting the thickness of the filter element to 1cm to 2cm, the thickness of the filter element is used to increase the area, which ensures both smooth airflow and high performance and long life of the filtration system itself.

[0106] The dust box provided by this utility model solves the key technical problem of high wind resistance and low efficiency caused by incomplete opening of the baffle in the prior art by reasonably setting the interval between the filter element and the air inlet baffle. This ensures the smooth flow of air in the dust box and significantly improves the suction efficiency. In addition, the dust box assembly is also equipped with a box body 1 with a low-lying area to guide the sedimentation of waste, a vibrating element 3 to actively clean the filter element 2, and a dust collection port 13 for automatic emptying. These structures synergistically improve the reliability of waste storage, the long-term performance of the filtration system, and the automation level of the whole machine, bringing users an efficient, convenient, and low-maintenance user experience.

[0107] A second aspect of this invention provides a cleaning device that includes the dust box assembly described above.

[0108] The aforementioned cleaning equipment can be a device capable of cleaning the surface being cleaned by suction airflow, such as a vacuum cleaner or a robotic vacuum cleaner. The dustbin assembly provided by this invention is detachably installed in the path of the suction airflow of the cleaning equipment to filter the suction airflow and collect debris such as dust or lighter, liftable foreign objects brought in by the suction airflow. The dustbin assembly installed in this cleaning equipment includes a unique internal air duct design, which greatly reduces airflow resistance at the dustbin inlet, thus achieving higher cleaning efficiency. Furthermore, by integrating a vibrating element 3, the cleaning equipment or the dustbin therein can automatically remove dust from the filter element 2 through the vibration element 3, giving the cleaning equipment an automatic self-maintenance capability.

[0109] In summary, cleaning equipment equipped with the aforementioned dustbin components offers higher cleaning efficiency, better long-term performance stability, and a higher degree of automation.
