Fig. 1 is a schematic structural view of a cleaning device provided by an embodiment of the present application; Fig. 2 is an exploded schematic diagram of a part of the structure of the dust bucket assembly in Fig. 1; Fig. 3a is a dust scraping device of the dust bucket assembly in Fig. 1 in its initial state Sectional view below. Please refer to accompanying drawings 1 to 3 a , the cleaning equipment provided in this embodiment includes: a body 10 , and a dust bucket assembly 20 disposed on the body 10 . Wherein, the dust bucket assembly 20 may be detachably fixed to the machine body 10 , or may be non-detachably fixed to the machine body 10 . The cleaning equipment provided in this embodiment may include, but not limited to, a handheld vacuum cleaner, an upright vacuum cleaner, a canister vacuum cleaner, and the like. The cleaning device in this embodiment is mainly improved on the dust bucket assembly 20 on the body 10, so as to make cleaning the dust bucket more convenient and convenient.

Specifically, the dust bucket assembly 20 includes: a dust bucket body 21 , a bottom cover 22 , a filter 23 and a dust scraping device 24 .

Wherein, the dust bucket body 21 can be installed on the machine body 10, and one end of the dust bucket body 21 can communicate with the dust suction port X of the cleaning device, and the other end of the dust bucket body 21 can be provided with the bottom cover 22.

In this embodiment, the bottom cover 22 is movably connected to the dust bucket body 21 . Specifically, the bottom cover 22 may be hinged to the dust bucket body 21 in a flip-over manner. Alternatively, the bottom cover 22 can be pivotally connected to the dust bucket body 21 , the rotation axis can be parallel to the axis of the dust bucket body 21 , and the bottom cover 22 can rotate along the plane where the cross section of the dust bucket body 21 is located. Alternatively, the bottom cover 22 can be slidably disposed on the dust bucket body 21 , and the bottom cover 22 can slide along the transverse direction of the dust bucket body 21 . Regardless of the way the bottom cover 22 is movably connected to the dust bucket body 21 , as long as the bottom cover 22 can move relative to the dust bucket body 21 to open or close the dust bucket, this embodiment of the present application does not limit it.

The filter 23 is disposed in the dust bucket body 21 . In an exemplary embodiment, the filter 23 can be detachably or non-detachably connected to the end of the dust bucket body 21 away from the bottom cover 22, and a power source can be provided above the filter 23 for the power source. Negative pressure is generated during operation, and the air with dust in the outside world is sucked into the dust bucket body 21 . A dust collection channel can be formed between the outer side wall of the filter 23 and the inner side wall of the dust bucket body 21, and the airflow with dust inhaled from the dust suction port X enters the dust collection channel, and then can pass through the adsorption of the filter 23 to carry out dust collection. The dust and gas are separated, and the clean air after the dust and gas separation can enter the power source through the inside of the filter 23 .

In addition, in some other embodiments, the filter 23 and the dust bucket body 21 can be detachably connected to the body 10 respectively, and the user can disassemble the dust bucket body 21 and the filter 23 from the body 10 respectively.

Generally, the filter 23 includes a filter screen, and the mesh holes on the filter screen can be designed to allow air to pass through, but cannot allow dust to pass through, so that dust and dirt can be adsorbed on the outer wall of the filter 23 . And because the air flow path will pass through the filter, in order to prevent the accumulation of dust and dirt on the filter 23 and affect the dust collection effect, it is necessary to clean the dust and dirt on the filter 23, so that To a certain extent, the dust collection effect is guaranteed.

In view of this, further, a dust scraping operation is performed on the filter 23 by providing a dust scraping device 24 . Specifically, at least part of the dust scraping device 24 is used to contact the filter 23 . More specifically, at least part of the dust scraping device 24 may be in contact with the outer sidewall of the filter 23 . The dust-scraping device 24 can move along a predetermined trajectory to at least perform a dust-scraping action on the filter 23 . In the embodiment of the present application, the filter 23 can be a cylindrical filter 23, and the outer peripheral sidewall of the cylindrical filter 23 is used to prevent dust and dirt from passing through, so that the dust and dirt are adsorbed on the cylindrical filter. 23 peripheral sidewalls. In some other embodiments, the filter screen portion of the filter 23 is not closed in the circumferential direction, for example, the filter screen in the filter 23 is only in the shape of a semi-arc, or only in a plane shape, etc., the embodiment of the present application is for The shape of the filter 23 is not limited.

In some embodiments, the predetermined trajectory may include a motion trajectory moving along the length of the filter 23 . When the filter 23 is a cylindrical filter, the filter screen on it is annular, and the dust-scraping part 241 of the dust-scraping device 24 can comprise a dust-scraping ring, and the cross-sectional size of the dust-scraping ring can be the same as that of the filter 23. Size matching, when using the dust scraping ring to perform the dust scraping action, the dust scraping ring can move along the length of the filter 23 to scrape off the dust and dirt on the filter 23 from top to bottom, or, the dust scraping ring Can move up and down along the length direction of the filter 23, and repeatedly scrape the peripheral side wall of the filter 23, so as to scrape off the dust and dirt on the filter 23 as much as possible. Since the dust-scraping ring surrounds the filter 23, the dust-scraping ring only needs to move along the length direction of the filter 23 during the dust-scraping process, which can greatly improve the dust-scraping efficiency. In addition, it can be understood that when the filter screen on the filter 23 is planar or semi-arc, the dust scraping component can only be a dust scraping block, and the width of the dust scraping block can match the width of the filter screen. During ash operation, move along the length direction of filter 23, all can reach the ash scraping operation of maximum efficiency.

Preferably, the cross-sections in the longitudinal direction of the cylindrical filter 23 can be equal, thus, when the scraping ring moves along the longitudinal direction of the filter 23, it can touch the outer peripheral side wall of the filter 23 and Reliable scraping operation.

It can be understood that, in some other embodiments, the dust-scraping part of the dust-scraping device 24 can not be limited to a dust-scraping ring, for example, can be a dust-scraping block (not shown in the figure), and the length of the dust-scraping block can be Equal to the length of the filter 23, when the dust scraping operation is required, the dust scraping block can move around the circumferential direction of the filter 23 in a circular motion, thereby scraping off the dust and dirt on the filter 23 along the circumferential direction .

Even, the length of the dust-scraping block can be less than the length of the filter 23. In this case, the dust-scraping block can move along the circumferential direction of the filter 23, and can move along the length direction of the filter 23 while moving along the circumferential direction. Move, thus, the dust scraping block can move around the outer peripheral side wall of the filter 23 in a spiral motion, and scrape off the dust and dirt on the filter 23 .

In addition, it should be noted that the cylindrical filter 23 does not limit the filter 23 to be cylindrical. In some embodiments, it can also be square or other cylindrical. The cross-sectional shape of the filter 23 is not limited. Do limited. The dust bucket body 21 is also not limited to a cylindrical shape, and its cross-sectional shape is also not limited. Moreover, the relative positional relationship between the dust bucket body 21 and the filter 23 in the lateral direction is not limited either. For example, in some embodiments, when the dust bucket body 21 is cylindrical, the filter 23 can also be cylindrical, and the two can be arranged coaxially (that is, the center line is coaxial). When the dust bucket body 21 is in the shape of a square cylinder, the filter 23 can also be in the shape of a square cylinder, and the centerlines of the two can coincide. When the dust bucket body 21 is cylindrical, the filter 23 may also be square cylindrical, and the axis of the dust bucket body 21 may coincide with the centerline of the filter 23 . When the dust bucket body 21 is a square cylinder, the filter 23 may also be a square cylinder, and the axis of the dust bucket body 21 may coincide with the centerline of the filter 23 . Of course, in some other embodiments, the centerline of the filter 23 may not coincide with the centerline of the dust bucket body 21, which is not limited in this embodiment of the present application.

In the embodiment of the present application, the dust scraping device 24 includes a force applying part 242 , and after the dust scraping device 24 moves to a preset position, the force applying part 242 can apply force to the bottom cover 22 to open the bottom cover 22 .

In some embodiments, the dust-scraping device 24 can continue to move along the direction defined by the above-mentioned predetermined trajectory so that the force application part 242 exerts force on the bottom cover 22 to open the bottom cover 22 . For example, the force applying part 242 moves along the length direction of the filter 23 to apply force to the bottom cover 22 to open the bottom cover 22 . In some embodiments, the dust scraping device 24 moves along the length direction of the filter 23 when performing the dust scraping action. Continue to move along the length direction of the bottom cover 22 to open the bottom cover 22, so that the dust and dirt scraped off in the dust bucket are discharged outside the dust bucket from the ash pouring port exposed by opening the bottom cover 22. Therefore, for the user side, the user only needs to drive the dust scraping device 24 to move along the predetermined trajectory to quickly realize the dust scraping and dust dumping operations, which effectively improves the cleaning efficiency of the dust bucket.

In some other embodiments, the direction defined by the movement trajectory of the dust scraping device 24 performing the dust scraping action may be different from the movement direction in which the dust scraping device 24 exerts force on the bottom cover 22 to open the bottom cover 22 . For example, when the dust-scraping component of the dust-scraping device 24 is a dust-scraping block, the dust-scraping device 24 moves circularly or spirally when performing the dust-scraping action, and when the action of opening the bottom cover 22 is performed, the dust-scraping device 24 Can move in a straight line.

However, no matter which of the above methods is adopted, the dust scraping device 24 can realize the operation of dust scraping and dust dumping, and compared with the prior art, the cleaning efficiency of the dust bucket can be effectively improved.

In addition, before the dust scraping device 24 moves to the preset position, the dust scraping action of the dust scraping device 24 is completed. Or, when the dust scraping device 24 moves to reach the preset position, the dust scraping action of the dust scraping device 24 is completed. As long as the dust-scraping device 24 is opening the bottom cover 22, the operation of the dust-scraping device 24 to scrape the filter 23 has been completed. Thus, when the bottom cover 22 is opened, the dust on the filter 23 and The dirt has basically been cleaned up and discharged from the dust bucket. Try to avoid continuing to scrape the dust after the bottom cover 22 is opened, which will cause the dust to rise to the surroundings.

Of course, in some other embodiments, the dust scraping device 24 may apply force to the bottom cover 22 to open the bottom cover 22 during the dust scraping action on the filter 23 . That is to say, when the dust-scraping device 24 moves to the preset position, the dust-scraping parts of the dust-scraping device 24 are still in contact with the filter 23, and the force-applying part 242 on the dust-scraping device 24 is exerting pressure on the bottom cover 22. When the force is applied, the dust scraping parts of the dust scraping device 24 can also perform the dust scraping action on the filter 23 at the same time, even when the bottom cover 22 has been opened, the dust scraping parts can continue to perform the dust scraping action on the filter 23 , until the dust-scraping component scrapes the dust to the filter 23.

In the technical solution provided by the embodiment of the present application, by setting the dust scraping device, the dust scraping device can move along a predetermined trajectory to scrape off the dust on the filter inside the dust bucket, and then fall into the bottom of the dust bucket body. After the dust scraping device moves to After the preset position, the force application part on the dust scraping device can apply force to the bottom cover at the bottom of the dust bucket body to open the bottom cover, thereby pouring out the dust in the dust bucket. The ash scraping and ash pouring operations are realized through a dust scraping device, which has a simple structure and convenient operation, greatly improves the efficiency of the user in cleaning the dust bucket, and improves the user experience of the entire cleaning equipment.

In order to realize the opening of the bottom cover 22 by the force application part 242, specific methods may include but not limited to the following:

For example, the force applying portion 242 can be used to apply a thrust force to the bottom cover 22 along the opening direction of the bottom cover 22 to open the bottom cover 22 . When the bottom cover 22 is opened by applying a pushing force to the bottom cover 22 , the rigidity of the force applying portion 242 can be as good as possible, so as to avoid breaking or deforming the force applying portion 242 during the pushing process.

Fig. 3b is an enlarged view of A in Fig. 3a; Fig. 4a is a cross-sectional view of the state where the dust scraping device of the dust bucket assembly in Fig. 1 is against the dust bucket cover; Fig. 4b is an enlarged view of B in Fig. 4a; 5 is a cross-sectional view of the dust bucket assembly in FIG. 1 when the dust bucket cover is opened. In the exemplary embodiment shown in FIGS. 3 b to 5 , the bottom cover 22 can be reversibly connected to the dust bucket body 21 , and the force applying portion 242 is used to apply a thrust force to the bottom cover 22 to open the bottom cover 22 . It can be understood that the force applying portion 242 can apply a thrust force to a position on the bottom cover 22 away from the rotational connection as much as possible, so as to push the bottom cover 22 away with less effort.

More specifically, in order to improve the assembly reliability of the bottom cover 22 and the dust bucket body 21, as shown in Fig. 221 is engaged with the other side of the dust bucket body 21 . The force application portion 242 can be used to push the buckle 221 along the direction in which the bottom cover is disengaged, so as to open the bottom cover 22 . The rotating shaft and buckle between the bottom cover 22 and the dust bucket body 21 can be arranged oppositely on both sides of the dust bucket body 21, so that the locking force between the bottom cover 22 and the dust bucket body 21 can be evenly distributed as much as possible.

As for the specific location and shape of the buckle 221, in an exemplary embodiment, the buckle 221 can extend from the outer edge of the bottom cover 22 and extend toward the side wall of the dust bucket body 21 to form a barb. shape. There may be a protruding portion 211 on the outer wall of the dust bucket body 21 , and a barb-shaped buckle 221 may be hooked to the protruding portion 211 to lock the bottom cover 22 at the ash dump port P of the dust bucket body 21 . In this way, the force applying part 242 can move outside the dust bucket body 21, so as to be able to move outside to resist the buckle 221, so that the buckle 221 moves away from the protruding part 211 until the buckle 221 disengages from the protrusion. Out of the part 211, and then the bottom cover 22 is turned over to the normal state, and the ash dump port P of the dust bucket body 21 is exposed.

In some other optional embodiments, the buckle 221 can be located on the bottom cover 22 and extend to the inside of the dust bucket body 21. There can be a protrusion (not shown) on the inner side wall of the dust bucket body 21. The bottom cover 22 can cooperate with the protruding part of the inner side wall of the dust bucket body 21 through the internal buckle 221, and also can lock the bottom cover 22 at the ash dump port P of the dust bucket body 21. However, in this embodiment, the force applying portion 242 moves inside the dust bucket body 21 to push against the buckle 221 .

In addition, in some embodiments, the protrusion can be replaced by other structures, as long as it can be hooked by the buckle 221 . For example, the outer wall or the inner wall of the dust bucket body 21 may have a recessed portion, and the buckle 221 is hooked into the recessed portion.

Specifically, in order to realize that the force applying part 242 unlocks the buckle 221 . In some embodiments, the movement of the dust scraping device 24 can drive the force application part 242 to move linearly in a direction away from the filter 23 . The force applying part 242 may have a first resisting surface C1, and the buckle 221 has a second resisting surface C2. The first resisting surface C1 and/or the second resisting surface C2 are inclined surfaces. During the linear movement in the direction of 22 , the first abutting surface C1 can abut against the second abutting surface C2 along the direction in which the bottom cover 22 is disengaged.

As shown in FIG. 4 a , when the first thrust surface C1 and/or the second thrust surface C2 are sloped surfaces, when the force applying portion 242 moves toward the bottom cover 22 , the first thrust surface C1 pushes toward the second thrust surface. The surface C2 exerts a laterally outward resisting force, and during the downward process of the force applying part 242, the greater the resisting force against the buckle 221, the closer the buckle 221 is to the disengaged state, until finally the buckle 221 is detached from the dust bucket body 21 The protrusion, the bottom cover 22 is opened.

Of course, in some other optional embodiments, the bottom cover 22 can also be magnetically engaged and locked with the dust bucket body 21 , and the force applying portion 242 pushes against the bottom cover 22 to overcome the connection between the bottom cover 22 and the dust bucket body 21 . The bottom cover 22 can be opened by the magnetic attraction force between them.

In some optional embodiments, the bottom cover 22 can be slidably connected to the dust bucket body 21 , and the sliding direction of the bottom cover 22 is the transverse direction of the dust bucket body 21 , and the force applying portion 242 is used to apply force to the bottom cover 22 along the transverse direction. The thrust force of sliding outwards in the direction to open the bottom cover 22. The so-called transverse direction of the dust bucket body 21 can be understood as any direction in the plane defined by the cross section of the dust bucket body 21. On the dust bucket body 21, there can be a slideway for the bottom cover 22 to slide. Sliding in the sliding path defined by the bucket body 21 is to open or close the ash dump port P of the dust bucket.

In a specific embodiment, when the bottom cover 22 is slid on the dust bucket body 21 along the lateral direction, and when the movement direction of the force application part 242 is along the length direction of the filter 23, the bottom cover 22 may have a The force-receiving part (not shown in the figure) that cooperates with the part 242. The contact surface of the force applying part 242 and/or the force receiving part can be a slope, so that when the force applying part 242 moves along the length direction of the filter 23 and pushes against the force receiving part, it can be decomposed into a lateral thrust on the force receiving part, Then push the bottom cover 22 to slide horizontally to open the bottom cover 22, exposing the ash pouring port P. As for how to convert the force of the force application part 242 in the vertical motion into the lateral motion of the bottom cover 22, there are many specific implementation methods, which are not limited to the above examples, and will not be repeated in the embodiment of the present application.

One end of the first sliding member 243 is connected to the dust scraping member 241 , and the other end extends away from the bottom cover 22 . The second sliding piece 244 is connected to the first sliding piece 243 through an intermediate transverse connecting piece 245 , and the second sliding piece 244 is drivingly connected to the force applying portion 242 .

It should be noted that, the second sliding piece 244 is drivingly connected with the force applying part 242, including the second sliding piece 244 is fixedly connected with the force applying part 242, and may also include the transmission of the second sliding piece 244 and the force applying part 242, such as the second The sliding member 244 applies force to the force applying portion 242 , so that the second sliding member 244 drives the force applying portion 242 to move.
