Description

Technical Field

[0001] This disclosure relates to the field of cleaning equipment technology, specifically to a dust collection device and a cleaning device. Background Technology

[0002] In existing cleaning equipment (such as vacuum cleaners and mite removers), a scraping mechanism is typically used in the dust collection system to clean the debris between the inner wall of the bin and the filter. Specifically, the scraping mechanism removes dust and debris adhering to the inner wall of the bin and the filter, pushing it to the bottom of the bin's interior and concentrating the debris at the bottom. In some designs, the user can further push the scraping mechanism to open the lid at the bottom of the bin, allowing for the emptying of the waste.

[0003] However, this design has significant drawbacks in practical applications: when the amount of garbage accumulated in the inner cavity of the bin is too large, the movement path of the scraping mechanism may be obstructed by the excessive garbage, and the scraping mechanism is prone to jamming due to a sudden increase in resistance, thus failing to complete the scraping action. In addition, for some dust collection devices with a design that links the scraping mechanism to the bottom cover, when the scraping mechanism is jammed, the unlocking mechanism of the bottom cover cannot be triggered normally, making it difficult for users to open the bin for cleaning through normal operation, resulting in a poor user experience. Utility Model Content

[0004] This disclosure provides a dust collection device and a cleaning equipment to address the problems existing in the prior art.

[0005] According to a first aspect of this disclosure, a dust collection device is provided, comprising:

[0006] A barrel body having an inner cavity, and a dust outlet communicating with the inner cavity is provided on the barrel body;

[0007] A cover, which is hinged to the barrel and configured to engage with the barrel via a locking part to seal the dust outlet;

[0008] The ash-scraping mechanism includes an ash-scraping part located in the inner cavity of the barrel, and an operating part movably disposed on the outer wall of the barrel; the operating part includes an operating button, which moves from an initial position along a first direction and has a first position that triggers the opening of the cover and a second position that triggers the movement of the ash-scraping part, wherein the first position is adjacent to the initial position along the first direction compared to the second position.

[0009] According to a second aspect of this disclosure, a dust collection device is also provided, comprising:

[0010] A barrel body having an inner cavity;

[0011] The ash-scraping mechanism includes an ash-scraping section located in the inner cavity, an operating section movably disposed outside the barrel body, and a transmission mechanism connected to the ash-scraping section; wherein, the transmission mechanism is provided with a mating section located in the movement path of the operating section along a first direction; the operating section includes an operating button, and when the operating button is in an initial position, there is a predetermined distance between the mating section and the operating button; the operating button is configured to have a degree of freedom of movement in the first direction relative to the mating section within the predetermined distance; the operating button moves from the initial position along the first direction and has a first position that triggers the opening of the cover and a second position that triggers the movement of the ash-scraping section, wherein the distance between the initial position and the second position is greater than the distance between the initial position and the first position.

[0012] According to a third aspect of this disclosure, a cleaning device is also provided, including a body and a dust collection device disposed on the body, the dust collection device being the dust collection device described in the first or second aspect of this disclosure.

[0013] One beneficial effect of this disclosure is that by optimizing the linkage design between the ash-scraping mechanism and the lid unlocking, it solves the jamming problem caused by the accumulation of garbage after ash scraping in the prior art. Specifically, the operation button moves in two stages along the first direction: the first stage triggers the lid to open, releasing the locking part from the lid, allowing the lid to separate from the bin and opening the dust outlet; the second stage, through the continuous movement of the operation button, drives the ash-scraping part to move within the bin. At this time, because the dust outlet is open, the garbage is more easily removed from the ash-scraping path by gravity, significantly reducing the risk of the ash-scraping part being stuck by garbage. Even in the case of excessive garbage accumulation within the bin, the user can still unlock and open the lid by operating the button, allowing some garbage to be discharged through the dust outlet, thus freeing up space for the ash-scraping mechanism to operate, ensuring that the ash-scraping mechanism can perform ash scraping normally, and improving the user experience.

Detailed Implementation

[0028] Various exemplary embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present disclosure.

[0029] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this disclosure or its application or use.

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

[0031] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0032] In this article, terms such as "up," "down," "front," "back," "left," and "right" are used only to indicate the relative positional relationship between related parts, rather than to define the absolute position of these related parts.

[0033] In this article, "first," "second," etc., are used only to distinguish one another, and not to indicate degree of importance, order, or prerequisite for each other.

[0034] In this document, terms such as “equal” and “same” are not strict mathematical and / or geometric limitations, but also include errors that are understandable to those skilled in the art and permissible in manufacturing or use.

[0035] This disclosure provides a cleaning device, which can be a handheld vacuum cleaner, an upright vacuum cleaner, a robotic vacuum cleaner, a robot vacuum cleaner / mop combo, a mite remover, or other cleaning devices with dust collection functions. Furthermore, the cleaning device can also be a base station, such as a robotic vacuum cleaner base station or a vacuum cleaner base station, etc., with dust collection functions. The cleaning device includes a body and a dust collection device mounted on the body. See also... Figure 1 The dust collection device includes a barrel 1 and a cover 2. The barrel 1 has an inner cavity 10 and a dust outlet 11 that communicates with the inner cavity 10. The cover 2 is hinged to the barrel 1 and is configured to be fastened to the barrel 1 by a locking part 21 to seal the dust outlet 11.

[0036] In one specific embodiment of this disclosure, a locking mechanism 12 is provided on the barrel 1. When the lid 2 is closed, the locking part 21 can engage with the locking mechanism 12, thereby keeping the lid 2 closed without external force. When the lid 2 is closed, a closed space for dust collection is formed in the inner cavity 10; when the lid 2 is open, the dust outlet 11 is opened, allowing the garbage collected in the inner cavity 10 to be poured out.

[0037] The cleaning equipment also includes a negative pressure motor mounted on the main body and connected to the inner cavity 10 of the dust collection device. When the cleaning equipment is started, the impeller of the negative pressure motor rotates at high speed to create a negative pressure environment in the inner cavity 10 of the dust collection device. At this time, outside air, under atmospheric pressure, carries dust, debris, hair, and other waste into the equipment through the suction port (such as a vacuum cleaner suction port, floor brush suction port, mite remover brush head suction port, base station dust collection suction port, etc.), and is transported to the inner cavity 10 of the dust collection device through the pipeline. The magnitude of the negative pressure directly determines the dust collection capacity of the equipment, and the sealing of the dust collection device, such as the cover 2 locking with the body 1 through the locking part 21 to seal the dust outlet 11, ensures the stable maintenance of the negative pressure environment.

[0038] like Figure 1 As shown, the dust collection device also includes a filter assembly 8 located in the inner cavity 10. The filter assembly 8 is usually a multi-layer filter structure or a cyclone separator, and its function is to separate solid waste from gas in the air. Under negative pressure, the air drawn into the inner cavity 10 carries waste particles (including dust, hair, debris, etc.) which are first filtered by the filter assembly 8. Large particles of waste (such as debris and hair) are directly settled to the bottom of the barrel 1 or blocked by the inner wall of the barrel due to gravity and airflow impact, and are temporarily stored in the lower part of the inner cavity 10. Fine dust particles will move upward with the airflow and be adsorbed on the filter screen on the outer wall of the filter assembly 8. The cleaned air can be discharged through the pores or internal channels of the filter assembly 8, enter the negative pressure motor, and finally be discharged to the outside from the air outlet of the equipment.

[0039] To facilitate cleaning of the inner wall of the barrel and the outer wall of the filter assembly 8, the dust collection device of this disclosure also includes a dust scraping mechanism, such as... Figure 1 As shown, the dust scraping mechanism includes a dust scraping section 3 located in the inner cavity 10 of the barrel 1, and an operating section 4 movably disposed outside the barrel 1. In one embodiment of this disclosure, the dust scraping section 3 is configured to be sleeved on the outside of the filter assembly 8. The dust scraping section 3 has a first scraper 31 extending toward the filter assembly 8 and a second scraper 32 extending toward the inner wall of the barrel 1. During the movement of the dust scraping section 3, the first scraper 31 and the second scraper 32 are configured to maintain contact with the outer wall of the filter assembly 8 and the inner wall of the barrel 1, respectively. In this way, by providing a dust scraping section 3, dust and debris on the filter assembly 8 and the inner wall of the barrel 1 can be cleaned simultaneously, thereby improving the cleaning efficiency of the dust collection device.

[0040] The operating part 4 is disposed on the outer wall of the barrel 1, allowing the user to control the movement of the scraper 3 by applying force to the operating part 4. In a specific embodiment of this disclosure, the operating part 4 includes an operating button 42, which protrudes from the outer wall of the barrel 1, facilitating the user to press and pull the operating button 42. The operating button 42 moves from an initial position along a first direction and has a first position that triggers the opening of the cover 2 and a second position that triggers the movement of the scraper 3, wherein the first position is closer to the initial position along the first direction than the second position. Specifically, during the movement of the operating button 42 along the first direction, it first reaches the first position and then the second position. During the movement of the operating button 42 from the initial position to the first position along the first direction, the operating part 4 can push the locking part 21 to unlock from the barrel 1 to open the cover 2; during the continued movement of the operating button 42 from the first position to the second position along the first direction, the operating part 4 can drive the scraper 3 to move along the first direction within the inner cavity 10 of the barrel 1.

[0041] In one specific embodiment of this disclosure, Figure 2 The direction indicated by the dashed arrow shown is the first direction. See also... Figure 1 and Figure 2 The first view direction is downward. The cover 2 can be located at the end of the bucket 1 away from the operation button 42, that is, at the bottom of the bucket 1, so that when the cover 2 is opened, some of the garbage in the inner cavity 10 can be discharged naturally from the dust outlet 11 under the action of gravity.

[0042] Furthermore, in one specific embodiment of this disclosure, see [link to specific embodiment]. Figure 2 , Figure 5 , Figure 6 and Figure 8 The operating unit 4 also includes a push rod 43 connected to the operating button 42 and extending along a first direction. The operating button 42 and the push rod 43 can be integrally formed to constitute the operating unit 4. When the operating button 42 moves to a first position along the first direction, the push rod 43 unlocks the locking part 21 from the barrel 1 to open the lid 2. This structural design allows the user to conveniently control the movement of the push rod 43 through the operating button 42, thereby unlocking and opening the lid 2.

[0043] In one specific embodiment of this disclosure, the locking part 21 is configured to be located on the movement path of the push rod 43. At this time, the bottom end of the push rod 43 can be aligned with the locking part 21, so that during the movement along the first direction, the bottom end of the push rod 43 can directly abut against the locking part 21 and disengage it from the locking mechanism 12. After unlocking, the cover 2 opens naturally under the action of gravity, thereby exposing the dust port 11.

[0044] In another specific embodiment of this disclosure, a transmission component can also be provided on the movement path of the push rod 43. The transmission component can further drive the locking part 21 to move and unlock. In this case, the bottom end of the push rod 43 can be configured to cooperate with the transmission component, so that during the movement along the first direction, the bottom end of the push rod 43 can trigger the transmission component, causing the transmission component to drive the locking part 21 to move to the position of disengaging from the locking mechanism 12. After unlocking, the cover 2 will naturally open under the action of gravity, thereby exposing the dust port 11.

[0045] This disclosure solves the problem of jamming caused by garbage accumulation after ash scraping in the prior art by optimizing the linkage design between the ash scraping mechanism and the unlocking of the cover 2. Specifically, the operation button 42 moves in two stages along the first direction: In the first stage, it triggers the cover to open, and the operation button 42 drives the push rod 43 to push the locking part 21, thereby releasing the lock on the cover 2, separating the cover 2 from the bucket 1 and opening the dust outlet; In the second stage, the continuous movement of the operation button 42 drives the ash scraping part 3 to move inside the bucket. At this time, because the dust outlet 11 is open, the garbage is more easily removed from the ash scraping path by gravity, significantly reducing the risk of the ash scraping part 3 being jammed by garbage. Even in the case of excessive garbage accumulation in the bucket 1, the user can still unlock and open the cover 2 by operating the operation button 42, and some garbage can be discharged through the dust outlet 11, thereby making room for the ash scraping mechanism to move, ensuring that the ash scraping mechanism can perform ash scraping normally, and improving the user experience.

[0046] In one embodiment of this disclosure, reference is made to Figure 3 , Figure 4 and Figure 7 The dust collection device includes a transmission mechanism connected to the scraper 3. The transmission mechanism has a mating part 51 located along the movement path of the operation button 42 in a first direction. The operation button 42 is configured to engage with the mating part 51 during its movement from a first position to a second position in the first direction, and drive the scraper 3 to move along the first direction via the transmission mechanism. It should be noted that when the operation button 42 engages with the mating part 51, the operation part 4 can drive the scraper 3 to move via the mating part 51. In a specific embodiment of this disclosure, refer to... Figure 4 The operation button 42 and the mating part 51 can be arranged opposite to each other, and a first elastic device can be provided between the operation button 42 and the mating part 51. The two ends of the first elastic device can respectively abut against the operation button 42 and the mating part 51. When the operation button 42 has not yet moved to the first position under the action of external force, the operation button 42 is insufficient to push the mating part 51 through the first elastic device under the action of the elastic force, and the scraper part 3 remains stationary at this time; during the process of the operation button 42 moving from the first position to the second position, the operation button 42 can drive the mating part 51 to move through the first elastic device under the action of external force, thereby driving the scraper part 3 to move.

[0047] The transmission mechanism connects the operating part 4 and the scraping part 3. During the movement of the operating button 42 to the first position, a transmission relationship has not yet been formed between the operating button 42 and the mating part 51, therefore it does not drive the transmission mechanism or the scraping part 3 to move, and the scraping part 3 remains stationary during this process. When the operating button 42 moves to the first position, the push rod 43 pushes the locking part 21 to unlock from the barrel 1, thereby opening the cover 2. As the operating button 42 continues to move along the first direction from the first position to the second position, the operating button 42 can engage with the mating part 51 at a certain moment, thus forming a transmission relationship, and thereby driving the scraping part 3 to move along the first direction via the transmission mechanism.

[0048] Specifically, when the operation button 42 is in the initial position, the distance between the mating part 51 and the mating position of the operation button 42 is greater than the distance the operation button 42 travels from the initial position to the first position. Here, the mating position refers to the side of the operation button 42 corresponding to the mating part 51, such as... Figure 4 As shown, in this embodiment, the bottom surface of the operation button 42 can be engaged with the mating part 51. Figure 2 The diagram shows the state when the operation button 42 is in the first position, at which time the cover 2 is open and the scraper 3 remains in the initial position at the top. Figure 3 The distance between the mating part 51 and the operation button 42 is shown when the operation button 42 is in the first position. Figure 4 The distance between the mating part 51 and the operation button 42 when the operation button 42 is in its initial position is shown. In the initial position, the distance between the bottom surface of the operation button 42 and the mating part 51 is denoted as M. After the operation button 42 begins to move in the first direction, it gradually moves closer to the mating part 51, thereby reducing the distance between the bottom surface of the operation button 42 and the mating part 51. During this process, the scraper 3 does not move. This ensures that when the operation part 4 pushes the locking part 21 to unlock the cover 2, it does not cause the scraper 3 to move, avoiding unnecessary interference and allowing the unlocking and scraping actions to proceed in an orderly manner.

[0049] In one embodiment of this disclosure, reference is made to Figure 4A first elastic device is provided between the operation button 42 and the mating part 51. The operation button 42 is configured such that the distance between it and the mating part 51 is adjustable under the action of the first elastic device. Specifically, when subjected to an external force, the operation button 42 can shorten the distance between itself and the mating part 51 by compressing the first elastic device; when the external force on the operation button 42 is removed, the operation button 42 is configured to move away from the mating part 51 under the action of the first elastic device and can return to its initial position. Specifically, during the movement of the operation button 42 from the initial position to the first position, the resistance of the deformation of the first elastic device is less than the resistance of the scraper part 3 along the first direction. By providing the first elastic device, this disclosure creates an adjustable space between the operation button 42 and the mating part 51, and enables the operation button 42 to automatically and elastically return to its original position after the external force is removed. Furthermore, it ensures that when the operation button 42 pushes the locking part 21 to unlock the cover 2, it will not cause the scraper part 3 to move.

[0050] In one embodiment of this disclosure, during the movement of the operation button 42 from the first position to the second position, the resistance to deformation of the first elastic device is greater than the resistance to movement of the scraper 3 along the first direction. It is understood that the compression deformation process of the first elastic device can have two stages. In the first stage, the resistance to deformation of the first elastic device is less than the resistance to movement of the scraper 3 along the first direction, at which time the scraper 3 and the transmission mechanism (including the mating part 51) can remain stationary. In the second stage, the resistance to deformation of the first elastic device is greater than the resistance to movement of the scraper 3 along the first direction, at which time the operation button 42 can push the mating part 51 to move along the first direction through the first elastic device, thereby driving the scraper 3 to move along the first direction. Specifically, in the first stage where the scraper 3 remains stationary, the operation button 42 can move to the first position, thereby opening the cover 2. This ensures that the cover 2 is opened first, followed by scraping, preventing the scraping mechanism from jamming.

[0051] In another embodiment of this disclosure, the resistance to deformation of the first elastic device is always less than the resistance to movement of the scraper part 3 along the first direction. When the operation button 42 moves to the first position, the first elastic device can reach its maximum deformation. For example, the first elastic device is a spring, and when the operation button 42 moves to the first position, the spring reaches a flattened state. During the movement of the operation button 42 from the first position to the second position, the user continues to push the operation button 42. Under the force applied by the user, the operation button 42 can push the mating part 51 to move along the first direction through the first elastic device, thereby driving the scraper part 3 to move along the first direction.

[0052] In one specific embodiment of this disclosure, reference is made to Figure 4 , Figure 6 and Figure 7A guide post 511 is provided on one of the mating part 51 and the operating button 42, and a guide hole 41 for mating with the guide post 511 is provided on the other. The first elastic device is a first spring 61 sleeved on the guide post 511, and the two ends of the first spring 61 abut against the corresponding end faces of the operating button 42 and the mating part 51, respectively. Specifically, as shown... Figure 3 As shown, the end face of the operation button 42 that is used to cooperate with the first spring 61 is the bottom surface of the operation button 42, and is denoted as the first end face 421; the end face of the mating part 51 that is used to abut against the other end of the first spring 61 is the upper end face of the mating part 51, and is denoted as the second end face 510.

[0053] In this embodiment, the guide post 511 is disposed on the mating part 51, and the operating part 4 passes through the guide post 511 via the guide hole 41; the first spring 61 is sleeved on the guide post 511 and pre-pressed between the first end face 421 of the operating button 42 and the second end face 510 of the mating part 51. Further, the top surface of the operating button 42 is designated as the third end face 422, and the top of the mating part 51 is also provided with a limiting block 514, the lower end face of which is designated as the fourth end face 5140. When the external force is removed, the third end face 422 abuts against the fourth end face 5140, and the limiting block 514 can limit the operating part 4, preventing it from dislodging under the elastic force of the first spring 61. The guide post 511 provides guidance and support for the first spring 61 and the operating part 4, ensuring stability and reliability during operation.

[0054] In one embodiment of this disclosure, reference is made to Figures 6 to 9 The transmission mechanism includes a U-shaped connecting rod 52, which is formed by a vertically extending first connecting rod 521, a second connecting rod 522, and a connecting section 523 for connecting the first connecting rod 521 and the second connecting rod 522. The first connecting rod 521, the second connecting rod 522, and the connecting section 523 can be integrally formed to form the U-shaped connecting rod 52. The first connecting rod 521 is connected to the mating part 51, and part of the first connecting rod 521 is located in the inner cavity 10 of the barrel body 1. The barrel body 1 is provided with a through hole for the first connecting rod 521 to extend out. The second connecting rod 522 is located in the inner cavity 10 of the barrel body 1. One end of its connecting rod is connected to the scraping part 3, and the other end is connected to the end of the first connecting rod 521 located in the inner cavity 10 through the connecting section 523.

[0055] like Figure 7As shown, an assembly hole 513 is provided on the mating part 51, and the first connecting rod 521 can be fixedly connected to the mating part 51 through the assembly hole 513. The U-shaped connecting rod 52 has a simple structure and can effectively transmit the movement of the operating part 4 to the scraping part 3 to realize the scraping function. The U-shaped connecting rod 52 connects the scraping part 3 inside the barrel 1 with the mating part 51 outside the barrel 1 through the through hole, so that the mating part 51, the U-shaped connecting rod 52 and the scraping part 3 form a whole. When the operating part 4 pushes the mating part 51 outside the barrel 1, the mating part 51 can drive the scraping part 3 to move together through the U-shaped connecting rod 52.

[0056] In one embodiment of this disclosure, such as Figure 6 and Figure 9 As shown, the wall of the barrel 1 has a stepped surface 13 that extends radially outward or inward. A through hole is provided on the stepped surface 13, and the first connecting rod 521 passes through the through hole at least partially. In this embodiment, the stepped surface 13 is set to extend radially outward, and a sealing element 14 is provided in the through hole. The sealing element 14 is sleeved on the first connecting rod 521. The sealing element 14 can have a certain elasticity, so that the first connecting rod 521 can move relative to the sealing element 14 under the action of external force, thereby realizing a dynamic sealing structure. This design not only ensures the smooth movement of the first connecting rod 521, but also effectively prevents dust leakage from the inner cavity 10 of the barrel 1, improving the sealing performance of the dust collection device.

[0057] In one embodiment of this disclosure, the dust collection device further includes a second elastic device, which is configured to reset the operating part 4, the transmission mechanism, and the dust scraping part 3 when the external force on the operating button 42 is removed. This allows the dust collection device to automatically reset after completing one dust scraping and emptying operation, facilitating the user's next operation and improving ease of use.

[0058] In one specific embodiment of this disclosure, reference is made to Figures 6 to 8 A guide rod 7 is provided on the outside of the barrel body 1, and a mounting hole 512 is provided on the mating part 51. The mating part 51 slides with the guide rod 7 through the mounting hole 512. The second elastic device is a second spring 62 sleeved on the guide rod 7. The second spring 62 is configured to drive the transmission mechanism, the ash scraping part 3, and the operating part 4 to reset through the mating part 51 after the external force on the operating button 42 is removed.

[0059] Specifically, the guide rod 7 passes through the mounting hole 512 on the mating part 51, and the mating part 51 can slide up and down along the guide rod 7 through the mounting hole 512. Figure 8As shown, the second spring 62, sleeved on the guide rod 7, can be pre-pressed below the mating part 51, thereby compressing the mating part 51 as it slides downwards. After the external force on the mating part 51 is removed, it provides a springback restoring force for the mating part 51, enabling the mating part 51 to drive the operating part 4, the U-shaped connecting rod 52, and the scraping part 3 to reset together. The cooperation between the guide rod 7 and the mounting hole 512 provides guidance for the reset of the transmission mechanism and the operating part 4, ensuring the accuracy and stability of the reset.

[0060] In one embodiment of this disclosure, reference is made to Figure 10 The push rod 43 is a telescopic rod, and a stop 15 is provided on the barrel 1 to restrict the degree of freedom of the telescopic rod's movement. During the movement of the operation button 42 along the first direction to the first position, the telescopic rod maintains its initial length to push the locking part 21. During the continued movement of the operation button 42 along the first direction from the first position to the second position, the telescopic rod is configured to retract under the restriction of the stop 15. In this embodiment, the push rod 43 can dynamically adjust its length at different stages of movement, ensuring smooth unlocking and dust scraping actions, while avoiding the overall structure and performance of the dust collection device being affected by the push rod 43 being too long.

[0061] Specifically, the telescopic rod includes a sleeve section 431, a telescopic section 432 fitted inside the sleeve section 431, and a third spring 433 pre-compressed between the sleeve section 431 and the telescopic section 432. A protrusion 434 may be provided on the telescopic section 432. During the movement of the operating button 42 along the first direction to the first position, the telescopic rod experiences no resistance, and the sleeve section 431 and the telescopic section 432 can move together, pushing the locking part 21 to open the cover 2. As the operating button 42 continues to move along the first direction from the first position to the second position, the protrusion 434 will abut against the blocking member 15, causing the telescopic section 432 to retract into the sleeve section 431, while simultaneously compressing and deforming the third spring 433. After the external force is removed, the telescopic section 432 can pop out under the elastic force of the third spring 433, allowing the telescopic rod to return to its original length.

[0062] This disclosure also provides a dust collection device, including a barrel 1 and a dust scraping mechanism. The barrel 1 has an inner cavity 10; the dust scraping mechanism includes a dust scraping part 3 located in the inner cavity 10, an operating part 4 movably disposed outside the barrel 1, and a transmission mechanism connected to the dust scraping part 3. The transmission mechanism is provided with a mating part 51 located in the movement path of the operating part 4 along a first direction; the operating part 4 includes an operating button 42, and when the operating button 42 is in an initial position, there is a predetermined distance between the mating part 51 and the operating button 42; the operating button 42 is configured to have a degree of freedom of movement in the first direction relative to the mating part 51 within the predetermined distance; the operating button 42 moves from the initial position along the first direction and has a first position that triggers the opening of the cover 2 and a second position that triggers the movement of the dust scraping part 3, wherein the distance between the initial position and the second position is greater than the distance between the initial position and the first position. After moving a predetermined distance along the first direction, the operating button 42 can engage with the mating part 51 to drive the dust scraping part 3 to move through the mating part 51 during continued movement in the first direction. The distance between the initial position and the first position can be set to be less than a predetermined distance, so that the operation button 42 can trigger the cover 2 to open as it moves from the initial position to the first position along the first direction, and drive the scraper 3 to move as it continues to move to the second position.

[0063] In one embodiment of this disclosure, a first elastic device is provided between the operation button 42 and the mating part 51. The operation button 42 is configured such that the distance between it and the mating part 51 is adjustable under the action of the first elastic device. When the external force on the operation button 42 is removed, the operation button 42 is configured to have a predetermined distance between it and the mating part 51 under the action of the first elastic device. During the process of the operation button 42 moving from the initial position to the first position, the resistance of the deformation of the first elastic device is less than the resistance of the scraper part 3 moving along the first direction.

[0064] The above structure sets a predetermined distance M between the mating part 51 and the operation button 42 in the first direction, and maintains the predetermined distance by the first elastic device, so that the scraper part 3 is not driven during the initial process of moving the operation button 42; until the predetermined distance is removed by the compression of the first elastic device, that is, during the process of the operation button 42 moving from the first position to the second position, the operation button 42 can drive the scraper part 3 to move, thereby realizing the scraping function.

[0065] Application scenarios

[0066] In household cleaning scenarios, the cleaning equipment is a vacuum cleaner, which includes a main body, a negative pressure motor, and a dust collection device installed on the main body. The negative pressure motor can create negative pressure in the inner cavity 10 of the dust collection device, thereby realizing the function of vacuuming.

[0067] The dust collection device also includes a filter assembly 8 located in the inner cavity 10. Under negative pressure, the garbage particles carried by the air drawn into the inner cavity 10 are first filtered by the filter assembly 8. Large garbage particles are directly settled to the bottom of the barrel 1 or blocked by the inner wall of the barrel due to gravity and airflow impact, and are temporarily stored in the lower part of the inner cavity 10. Fine dust particles will move upward with the airflow and be adsorbed on the filter screen on the outer wall of the filter assembly 8. The cleaned air can be discharged through the pores or internal channels of the filter assembly 8, enter the negative pressure motor, and finally be discharged to the outside from the air outlet of the equipment.

[0068] After using the vacuum cleaner, the dust collection device needs to be cleaned. The user can manually press the operation button 42. When the operation button 42 moves from its initial position to its first position along the first direction, the push rod 43 can push the locking part 21 to unlock from the barrel 1, thus opening the cover 2. The user then continues to press the operation button 42. During the movement from the first position to the second position along the first direction, the operation button 42 drives the mating part 51, the U-shaped connecting rod 52, and the dust scraper 3 to move together along the first direction. The dust scraper 3 can simultaneously clean the dust and debris on the filter assembly 8 and the inner wall of the barrel 1 during this movement.

[0069] The operating unit 4 moves in two stages along the first direction: In the first stage, it pushes the locking part 21 to release the lock on the cover 2, separating the cover 2 from the bucket 1 and opening the dust outlet; in the second stage, the continuous movement of the operating unit 4 drives the scraper 3 to move inside the bucket. At this time, because the dust outlet 11 is open, the garbage is more easily removed from the scraping path by gravity, significantly reducing the risk of the scraper 3 being stuck by garbage. Even if there is excessive accumulation of garbage inside the bucket 1, the user can still unlock and open the cover 2 through the operating unit 4, and some garbage can be discharged through the dust outlet 11, thereby making room for the scraper mechanism to move and ensuring that the scraper mechanism can scrape normally, improving the user experience.
