In addition, the character "/" herein generally indicates that the former and latter related objects are in an "or" relationship.

Fig. 1 is a schematic structural diagram of a cleaning apparatus according to an embodiment of the present application; FIG. 2 is an exploded view of a portion of the structure of the dirt cup assembly of FIG. 1; FIG. 3a is a cross-sectional view of the dirt cup assembly of FIG. 1 in an initial state. Referring to fig. 1 to fig. 3a, the cleaning apparatus provided in this embodiment includes: a machine body 10, and a dust bucket assembly 20 provided to the machine 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 device provided in the present embodiment may include, but is not limited to, a hand-held cleaner, an upright cleaner, a canister cleaner, and the like. The cleaning device of the embodiment is mainly improved for the dust barrel assembly 20 on the machine body 10, so that the dust barrel can be cleaned more conveniently and conveniently.

Specifically, the dirt cup assembly 20 includes: a dust barrel 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 be communicated 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 main body 21. Specifically, the bottom cover 22 may be hinged to the dust bucket body 21 in a flip manner. Alternatively, the bottom cover 22 can be pivotally connected to the main body 21, the rotation axis can be parallel to the axis of the main body 21, and the bottom cover 22 can rotate along the plane of the cross section of the main body 21. Alternatively, the bottom cover 22 may be slidably disposed on the dust barrel body 21, and the bottom cover 22 may be slidable along the transverse direction of the dust barrel body 21. No matter what kind of mode swing joint is adopted with dirt bucket body 21 to bottom 22, as long as can realize bottom 22 for the motion of dirt bucket body 21 to can open or seal the dirt bucket can, this application embodiment does not do the restriction.

The filter 23 is provided in the dust bucket body 21. In an exemplary embodiment, the filter 23 may be detachably or non-detachably connected to an end of the dust bucket body 21 away from the bottom cover 22, and a power source may be provided above the filter 23, and the power source is operated to generate a negative pressure to suck the outside air with dust into the dust bucket body 21. The outer side wall of the filter 23 and the inner side wall of the dust barrel body 21 can form a dust collecting channel, the air flow with dust sucked from the dust suction port X enters the dust collecting channel, then the air flow can be adsorbed by the filter 23 to separate dust and air, and the clean air after dust and air separation can enter the power source through the inside of the filter 23.

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

Typically, the filter 23 includes a filter screen, and the filter screen can be designed to allow air to pass through and then prevent dust from passing through, so that dust and dirt can be adsorbed on the outer side wall of the filter 23. Since the airflow path passes through the filter, in order to prevent the dust and dirt on the filter 23 from being accumulated and affecting the dust collection effect, the dust and dirt on the filter 23 need to be cleaned, so that the dust collection effect is ensured to a certain extent.

In view of this, further, the filter 23 is subjected to an ash scraping operation by providing an ash scraping device 24. In particular, at least part of the ash scraping device 24 is intended to be in contact with the filter 23. More specifically, at least a portion of the dust scraping device 24 may be in contact with an outer sidewall of the filter 23. The ash scraping device 24 is movable along a predetermined trajectory to perform at least an ash scraping action on the filter 23. In the present embodiment, the filter 23 may be a cylindrical filter 23, and an outer peripheral side wall of the cylindrical filter 23 is used to block dust and dirt from passing through, so that the dust and dirt are adsorbed on the outer peripheral side wall of the cylindrical filter 23. In other embodiments, the filter screen portion of the filter 23 is not closed along the circumferential direction, for example, the filter screen in the filter 23 is only in a half-arc shape, or is only in a plane shape, and the shape of the filter 23 is not limited in the embodiments of the present application.

In some embodiments, the predetermined trajectory may include a motion trajectory that moves along a length of the filter 23. When the filter 23 is a cylindrical filter, the filter screen thereon is annular, and the dust scraping component 241 of the dust scraping device 24 may include a dust scraping ring, the cross-sectional dimension of the dust scraping ring may match the cross-sectional dimension of the filter 23, and when the dust scraping action is performed by using the dust scraping ring, the dust scraping ring may move along the length direction of the filter 23 so as to scrape off dust and dirt on the filter 23 from top to bottom, or the dust scraping ring may move up and down along the length direction of the filter 23 to scrape the outer circumferential side wall of the filter 23 repeatedly so as to scrape off dust and dirt on the filter 23 as much as possible. Because the ash scraping ring surrounds the filter 23, the ash scraping ring only needs to move along the length direction of the filter 23 in the ash scraping process, and the ash scraping efficiency can be greatly improved. In addition, it can be understood that when the filter screen on the filter 23 is planar or semi-arc shaped, the ash scraping component can be only the ash scraping block, the width of the ash scraping block can be matched with the width of the filter screen, and when the ash scraping operation is performed, the ash scraping operation can be performed with the maximum efficiency by moving along the length direction of the filter 23.

Preferably, the cross-section of each longitudinal portion of the cylindrical filter 23 may be equal, so that the dust scraping ring can contact the outer circumferential side wall of the filter 23 to reliably scrape dust when moving in the longitudinal direction of the filter 23.

It will be understood that in other embodiments, the dust-scraping component of the dust-scraping device 24 may not be limited to a dust-scraping ring, and may be, for example, a dust-scraping block (not shown), the length of which may be equal to the length of the filter 23, and when the dust-scraping operation is required, the dust-scraping block may move in a circular motion around the filter 23 in the circumferential direction, so as to scrape off dust and dirt on the filter 23 in the circumferential direction.

Even, the length of the dust scraping block may be smaller than that of the filter 23, in which case the dust scraping block may move in the circumferential direction of the filter 23 and may move in the longitudinal direction of the filter 23 while moving in the circumferential direction, whereby the dust scraping block may move in a spiral motion around the outer circumferential side wall of the filter 23 to scrape off dust and dirt on the filter 23.

The cylindrical filter 23 is not limited to the cylindrical filter 23, and may be a square cylinder or other cylindrical filter in some embodiments, and the cross-sectional shape of the filter 23 is not limited. The dust bucket body 21 is not limited to a cylindrical shape, and the cross-sectional shape thereof is not limited. Also, the relative positional relationship of both the dust bucket body 21 and the filter 23 in the transverse direction is not limited. For example, in some embodiments, when the main body 21 is cylindrical, the filter 23 may also be cylindrical, and both may be disposed coaxially (i.e., with a common centerline). When the dust bucket body 21 has a square cylindrical shape, the filter 23 may have a square cylindrical shape, and the center lines of the filter and the filter may coincide with each other. 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 center line of the filter 23. When the dust bucket body 21 has a square cylindrical shape, the filter 23 may have a square cylindrical shape, and the axis of the dust bucket body 21 may coincide with the center line of the filter 23. Of course, in other embodiments, the center line of the filter 23 may not coincide with the center line of the dust bucket body 21, and the embodiment of the present application is not limited thereto.

In the embodiment of the present application, the dust scraper 24 includes a force application portion 242, and after the dust scraper 24 moves to reach the preset position, the force application portion 242 can apply a force to the bottom cover 22 to open the bottom cover 22.

In some embodiments, the ash scraping device 24 may continue to move in the direction defined by the predetermined trajectory to cause the force application portion 242 to apply a force to the bottom cover 22 to open the bottom cover 22. For example, the urging portion 242 moves in the longitudinal direction of the filter 23 to apply an urging 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, and when the bottom cover 22 is opened by the force application portion 242, the dust scraping device 24 may still move along the length direction of the filter 23 to open the bottom cover 22, so that the dust and dirt scraped from the dust bin are discharged out of the dust bin from the dust pouring port exposed by the opened bottom cover 22. Therefore, for the user side, the user only needs to drive the dust scraping device 24 to move along the preset track all the time to quickly scrape dust and pour the dust, and the cleaning efficiency of the dust barrel is effectively improved.

In other embodiments, the direction defined by the motion trajectory of the ash scraping device 24 for performing the ash scraping action may not coincide with the motion direction of the ash scraping device 24 for applying a force to the bottom cover 22 to open the bottom cover 22. For example, when the dust-scraping member of the dust-scraping device 24 is a dust-scraping block, the dust-scraping device 24 moves in a circular or spiral shape when performing the dust-scraping action, and the dust-scraping device 24 may move in a straight line when performing the action of opening the bottom cover 22.

However, no matter which way is adopted, the operation of scraping dust and pouring dust can be realized through the dust scraping device 24, and compared with the prior art, the cleaning efficiency of the dust barrel can be effectively improved.

In addition, before the ash scraping device 24 moves to reach the preset position, the ash scraping action of the ash scraping device 24 is finished. Alternatively, when the ash scraping device 24 moves to reach the preset position, the ash scraping action of the ash scraping device 24 is finished. As long as the dust scraping device 24 finishes the dust scraping operation of the filter 23 when the dust scraping device 24 performs the action of opening the bottom cover 22, it can be ensured that the dust and dirt on the filter 23 are basically cleaned and discharged out of the dust barrel when the bottom cover 22 is opened, and the dust is prevented from being raised to the surroundings as far as possible when the dust scraping device continues to perform the dust scraping operation after the bottom cover 22 is opened.

Of course, in other embodiments, the dust scraping device 24 may apply a force to the bottom cover 22 to open the bottom cover 22 during the dust scraping action performed on the filter 23. That is, when the dust scraper 24 moves to the preset position, the dust scraping component of the dust scraper 24 still contacts with the filter 23, and the force applying portion 242 on the dust scraper 24 applies a force to the bottom cover 22, the dust scraping component of the dust scraper 24 can also perform a dust scraping action on the filter 23 at the same time, and even in a state where the bottom cover 22 is already opened, the dust scraping component can continue to perform a dust scraping action on the filter 23 until the dust scraping component scrapes the filter 23.

To open the bottom cover 22 by the force application part 242, the following methods may be specifically included but not limited to:

for example, the urging portion 242 may be used to apply an urging force to the bottom cover 22 in the opening direction of the bottom cover 22 to open the bottom cover 22. When the bottom cover 22 is opened by applying the pushing force to the bottom cover 22, the rigidity of the force application portion 242 may be as good as possible to prevent the force application portion 242 from being broken or deformed during the pushing process.

FIG. 3b is an enlarged view of FIG. 3a at A; FIG. 4a is a cross-sectional view of the dirt cup assembly of FIG. 1 with the dirt cup scraping device positioned against the dirt cup lid; FIG. 4B is an enlarged view of the portion B in FIG. 4 a; FIG. 5 is a cross-sectional view of the dirt tray assembly of FIG. 1 with the dirt tray lid open. In the exemplary embodiment shown in fig. 3b to 5, the bottom cover 22 can be connected with the dust bucket body 21 in a reversible manner, and the force application part 242 is used for applying a pushing force to the bottom cover 22 to open the bottom cover 22. It can be understood that the urging portion 242 may urge 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 assembling reliability of the bottom cover 22 and the dust bucket body 21, as shown in fig. 3a to 4b, the bottom cover 22 and one side of the dust bucket body 21 can be connected in a reversible manner, and the bottom cover 22 can be connected with the other side of the dust bucket body 21 in a clamping manner through a fastener 221. The force application part 242 can be used to push the buckle 221 in the direction that the bottom cover is disengaged from the buckle, so as to open the bottom cover 22. The rotating shaft and the buckle between the bottom cover 22 and the dust bucket body 21 can be oppositely arranged on two sides of the dust bucket body 21, so that the locking force between the bottom cover 22 and the dust bucket body 21 is distributed uniformly as much as possible.

With respect to the specific arrangement position and the specific shape of the latch 221, in an exemplary embodiment, the latch 221 may extend from the outer edge of the bottom cover 22 and extend in a barb shape toward the side wall of the dust bucket body 21. A protrusion 211 may be formed on an outer sidewall of the dust bucket body 21, and a hook-shaped latch 221 may be hooked on the protrusion 211 to lock the bottom cover 22 at the dust dumping port P of the dust bucket body 21. In this manner, the force application portion 242 can move outside the dust bucket body 21 to move outside to push against the buckle 221, so that the buckle 221 moves away from the protrusion 211 until the buckle 221 disengages from the protrusion 211, and the bottom cover 22 is turned to the present state, and the dust pouring port P of the dust bucket body 21 is exposed.

In other alternative embodiments, the fastener 221 can be located on the bottom cover 22 and extend into the dust bucket body 21, a protrusion (not shown) can be provided on the inner sidewall of the dust bucket body 21, and the bottom cover 22 can be engaged with the protrusion on the inner sidewall of the dust bucket body 21 through the internal fastener 221, and can also lock the base 22 at the dust pouring opening P of the dust bucket body 21. However, in this embodiment, the urging portion 242 moves inside the dust bucket body 21 to push the catch 221.

In addition, in some embodiments, the protrusion may be replaced by other structures as long as the catch 221 can be hooked. For example, the dust bucket body 21 may have a recess on an outer or inner side wall thereof, and the catch 221 may be hooked on the recess.

Specifically, the latch 221 is unlocked to realize the urging portion 242. In some embodiments, the movement of the ash scraping device 24 can drive the force application portion 242 to move linearly in a direction away from the filter 23. The force application portion 242 may have a first abutting surface C1, the buckle 221 has a second abutting surface C2, the first abutting surface C1 and/or the second abutting surface C2 are inclined surfaces, and the first abutting surface C1 can abut against the second abutting surface C2 along a direction in which the bottom cover 22 is disengaged during the process of the force application portion 242 moving linearly toward the bottom cover 22.

As shown in fig. 4a, when the first abutting surface C1 and/or the second abutting surface C2 are inclined surfaces, the first abutting surface C1 applies a laterally outward abutting force to the second abutting surface C2 during the movement of the force application portion 242 toward the bottom cover 22, and the greater the abutting force of the force application portion 242 on the latch 221 during the descending process, the closer the latch 221 is to the disengaged state, and finally, the bottom cover 22 is opened until the latch 221 disengages from the protrusion on the dust bucket body 21.

Of course, in some other alternative embodiments, the bottom cover 22 can also be magnetically attracted to and locked with the dust barrel body 21, and the force application portion 242 pushes the bottom cover 22 to overcome the magnetic attraction between the bottom cover 22 and the dust barrel body 21, so as to open the bottom cover 22.

In some alternative embodiments, the bottom cover 22 can be slidably connected to the dust bucket body 21, the sliding direction of the bottom cover 22 is a transverse direction of the dust bucket body 21, and the force application portion 242 is used for applying a pushing force to the bottom cover 22 to slide outwards in the transverse direction so as to open the bottom cover 22. The transverse direction of the dust bucket body 21 can be any direction in a plane defined by the cross section of the dust bucket body 21, and the dust bucket body 21 can be provided with a slide way for sliding the bottom cover 22, and the bottom cover 22 slides in the slide way defined by the dust bucket body 21 to open or close the dust pouring port P of the dust bucket.

In an embodiment, when the bottom cover 22 is slidably disposed on the dust barrel body 21 in the transverse direction, and when the movement direction of the force application portion 242 is along the length direction of the filter 23, the bottom cover 22 may have a force application portion (not shown) engaged with the force application portion 242. The contact surface of the force application portion 242 and/or the force receiving portion may be an inclined surface, so that when the force application portion 242 moves along the length direction of the filter 23 and pushes against the force receiving portion, the force can be decomposed into a thrust force in the transverse direction of the force receiving portion, and the bottom cover 22 is pushed to slide in the transverse direction to open the bottom cover 22, so as to expose the dust pouring port P. How to specifically realize that the acting force of the force application part 242 moving vertically is converted into the transverse movement of the bottom cover 22, there are many specific implementation manners, which are not limited to the foregoing exemplary manner, and details are not described in the embodiment of the present application.

In other embodiments, as shown in fig. 3a, 4a and 5, when the bottom cover 22 is connected with the dust barrel body 21 in a reversible manner, the bottom cover 22 may include a first side S1 and a second side S2 on both sides of the rotation axis, the first side S1 is used for closing the dust barrel body 21, and the second side S2 is connected with the force application part 242.

The urging portion 242 is used to pull the second side S2 in a direction toward the dust bucket body 21 so that the bottom cover 22 is turned over to open the bottom cover 22. To achieve that the force application portion 242 pulls the second side S2 towards the dust bucket body 21, in some embodiments, the force application portion 242 may be located on a different side of the dust bucket body 21 from the dust scraping component of the dust scraping device 24, the force application portion 242 itself may be a flexible connecting member, or the force application portion 242 may be a rigid member, and the force application portion 242 and the dust scraping device 24 may be connected by a flexible connecting member.
