Finally, the benefits of the dirt cup assembly 100 are briefly described.

According to the dust cup assembly 100 provided by the embodiment of the invention, the cup shell assembly 1 is matched with the cyclone cone assembly 2, so that a cyclone air channel can be formed in the cup shell 11, and the dust cup assembly 100 has a good dust-air separation effect and high efficiency. In addition, the first through hole 2111 and the second through hole 2121 are formed in the cyclone cone 21, so that the cyclone air duct is changed into a double-cyclone air duct positioned on the inner side and the outer side of the cyclone cone 21, dust with different weights and different volumes can be separated in different cyclone air ducts respectively, and the dust-air separation effect and efficiency are further improved. In addition, the dust cup assembly 100 is simple in structure, easy to assemble, high in assembly efficiency, high in accuracy and high in reliability.

Referring now to fig. 1-9, a dirt cup assembly 100 in accordance with an embodiment of the first aspect of the present invention is described.

A dirt cup assembly 100 according to an embodiment of the present invention includes: a cup housing 11, a cyclonic separating member (such as the cyclone cone 21 or multi-cone structure described herein, etc.) and a partition 22. As shown in fig. 3 and 4, the cup housing 11 is a hollow housing, the cyclone separating member is disposed in the cup housing 11 to divide the inner space of the cup housing 11 into an outer chamber 110 outside the cyclone separating member and an inner chamber 210 inside the cyclone separating member, wherein the partition 22 is disposed between the cup housing 11 and the cyclone separating member (i.e., disposed in the outer chamber 110) to divide the space between the cup housing 11 and the cyclone separating member into a cyclone chamber 1101 and a dust collecting chamber 1102 (i.e., the outer chamber 110 is divided into the cyclone chamber 1101 and the dust collecting chamber 1102), wherein the cyclone chamber 1101 is a location for cyclone separation, and the dust collecting chamber 1102 is a location for dust collection.

As shown in fig. 3 and 4, the cyclone chamber 1101 is an annular space surrounding the cyclone separating element, that is, the cyclone chamber 1101 is disposed around the cyclone separating element, and each cross section of the cyclone chamber 1101 is an annular (not limited to a circular ring, but may also be an elliptical ring) surface. Thus, airflow into the cyclone chamber 1101 (as shown by the arrow B in FIG. 3) can be cyclonic around the outer surface of the cyclonic separating member within the cyclone chamber 1101 (as shown by the arrow C in FIG. 3). Wherein "cyclonic separation" means: when the airflow moves rapidly along the circular or spiral path, the dust (i.e. the dirt particles) in the airflow can be thrown out of the airflow under the action of strong centrifugal force, so that the dust and the air are separated.

As shown in fig. 3 and 4, the cyclone chamber 1101 is located above the dust collection chamber 1102, the partition 22 has a dust discharge port 2201, and the cyclone chamber 1101 communicates with the dust collection chamber 1102 through the dust discharge port 2201, so that dust separated by cyclone in the cyclone chamber 1101 can fall into the dust collection chamber 1102 through the dust discharge port 2201. In short, after the airflow enters the cyclone chamber 1101 for cyclone separation, the centrifugally thrown-out dust can naturally fall into the dust collecting chamber 1102 through the dust discharge port 2201 under the action of gravity (as shown by arrows B to C to D in FIG. 3).

Here, it should be noted that the phrase "the cyclone chamber 1101 is located above the dust collection chamber 1102" means that at least a portion of the cyclone chamber 1101 opposite to the dust discharge port 2201 "is located above at least a portion of the dust collection chamber 1102 opposite to the dust discharge port 2201", so that the dust separated from the cyclone chamber 1101 can naturally fall into the dust collection chamber 1102 under the action of the height difference, thereby greatly reducing the structural complexity and making the dust cup assembly 100 more suitable for production and application.

According to the dust cup assembly 100 of the embodiment of the invention, the outer cavity 110 is divided into the cyclone chamber 1101 and the dust collecting chamber 1102 separated by the partition 22 arranged between the cup shell 11 and the cyclone separating piece, and the dust discharge port 2201 communicating the cyclone chamber 1101 and the dust collecting chamber 1102 is opened on the partition 22. Therefore, on one hand, dust can be more fully separated in the annular cyclone chamber 1101, and on the other hand, the dust separated by cyclone can be discharged into the dust collecting chamber 1102 below the cyclone chamber 1101 through the dust discharge port 2201, so that the problem that the dust is rolled up again by airflow flowing in cyclone is effectively avoided, and the cyclone separation effect is obviously improved. In summary, the dirt cup assembly 100 according to the embodiment of the present invention has a simple structure, is easy to process and implement, and can effectively achieve cyclone separation, thereby obtaining an excellent cyclone separation effect.

In some embodiments of the present invention, referring to fig. 7-9 in combination with fig. 3 and 4, the cyclone separating element is a cyclone cone 21, the separating element 22 is an annular plate (for example, a closed annular plate, such as a circular annular plate, an elliptical annular plate, etc., and for example, a non-closed annular plate, such as a C-shaped plate, etc.) and is disposed between the outer circumferential surface of the cyclone cone 21 and the inner surface of the cup 11 (i.e., the inner annular wall of the separating element 22 is tightly attached to one (closed or non-closed) circumferential ring on the outer circumferential surface of the cyclone cone 21, the outer annular wall of the separating element 22 is tightly attached to one (closed or non-closed) circumferential ring on the inner surface of the cup 11, and the cyclone chamber 1101 and the dust collecting chamber 1102 are respectively located at two sides in the thickness direction of the separating element 22.

Here, it should be noted that the term "cyclone cone" refers to: cyclone separator with a cone-shaped outer shape, wherein the cone-shaped outer shape refers to that: a cylinder whose cross-sectional area is gradually reduced in the direction of its own axis (the cross-section is not limited to a circle, and may be, for example, an ellipse). In addition, it should be noted that "cyclone cone" is different from "multi-cone structure", and "cyclone cone" refers to only one conical cylinder, and the end areas of the two axial ends of the conical cylinder have a small difference, and "multi-cone structure" refers to a plurality of pointed small conical cylinders arranged in an annular array, wherein the end areas of the two axial ends of each pointed small conical cylinder have a large difference.

Therefore, the cyclone chamber 1101 surrounding the cyclone cone 21 can be simply and effectively defined by the matching of the cyclone cone 21 and the annular plate-shaped partition 22, so that the peripheral wall surface 211 of the cyclone cone 21 can be used as the inner annular wall of the cyclone chamber 1101, the cyclone separation effect of the cyclone chamber 1101 is improved, and the production and implementation difficulty of the dust cup assembly 100 is reduced. In addition, the inner cavity of the cyclone cone 21 is also formed into a frustum shape, so that the airflow entering the inner cavity of the cyclone cone 21 can be subjected to cyclone separation, and the overall dust removal effect of the dust cup assembly 100 is further improved.

In some preferred examples of the present invention, referring to fig. 5 and 6, the cup housing 11 may have a cylindrical shape, for example, the cup housing 11 may have a cylindrical or conical shape (but not limited to a cylindrical shape, a conical shape, and an elliptical cylindrical shape, for example), and at this time, the outer annular wall of the partition 22 may closely fit with a circumference on the inner circumferential surface of the cup housing 11. Therefore, the structure of the cyclone chamber 1101 is better, and the cyclone separation effect is more beneficial to improvement. Further preferably, the cup housing 11 may be arranged coaxially or substantially coaxially with the cyclone cone 21, i.e. the central axis of the cyclone cone 21 and the central axis of the cup housing 11 may coincide or be parallel, so as to facilitate the installation and processing, and the cyclone separation effect of the cyclone chamber 1101 is better.

In some preferred examples of the present invention, the central axis of the cyclone cone 21 is non-perpendicular to the plane of the partition 22, that is, the central axis of the cyclone cone 21 is disposed non-parallel to, i.e., at an angle to, the central axis of the inner ring of the partition 22. For example, when the central axis of the cyclone cone 21 is vertically disposed, the plane of the partition 22 is not horizontally disposed. Therefore, the layout of the cyclone chamber 1101 and the dust collecting chamber 1102 is better, and the cyclone separation effect is better. Preferably, the partition 22 has a slightly lower portion where the dust discharge port 2201 is formed, so that the dust can be discharged from the dust discharge port 2201 into the dust collection chamber 1102 more effectively, the dust discharge efficiency is high, and the dust discharge effect is reliable.

Of course, the present invention is not limited to this, and in some alternative examples of the present invention, the central axis of the cyclone cone 21 and the plane of the partition 22 may also be perpendicular, that is, the central axis of the cyclone cone 21 and the central axis of the inner ring of the partition 22 may coincide or be parallel. For example, when the central axis of the cyclone cone 21 is vertically disposed, the plane in which the partition 22 is located is horizontally disposed, thereby facilitating the processing and installation.

Preferably, the partition 22 is in one piece with the cyclone cone 21. That is, the partition 22 is not detachable from the cyclone cone 21. For example, the partition 22 and the cyclone cone 21 may be a single-piece molded article formed by injection molding at the same time, or a single-piece molded article formed by two-shot injection molding, or the like. Therefore, the assembly steps can be simplified, the subsequent assembly of the cup shell 11 and the cup shell is facilitated, and the production efficiency is improved. In addition, when the partition 22 and the cyclone cone 21 are an integral piece, the stability of the relative position relationship between the partition 22 and the cyclone cone 21 is stronger, so that the working effect of the dust cup assembly 100 is more reliable, effective and stable.

In some embodiments of the invention, referring to fig. 4 and 9, the cyclone separator further has a first through hole 2111 communicating between the interior of the cyclone separator and the cyclone chamber 1101, so that the airflow separated in the cyclone chamber 1101 can directly enter the cyclone separator through the first through hole 2111 for re-cyclone separation. Therefore, the dust cup assembly 100 can simply, conveniently and quickly realize secondary cyclone separation, namely primary cyclone separation is carried out outside the cyclone separation piece, and secondary cyclone separation is carried out inside the cyclone separation piece, so that the dust removal effect of the dust cup assembly 100 is further improved.

Further, referring to fig. 4 and 9, the cyclone is further provided with a second through hole 2121 communicating between the inside of the cyclone and the dust collection chamber 1102, so that the dust re-cyclone separated in the cyclone is discharged into the dust collection chamber 1102 through the second through hole 2121. Therefore, the dust separated in the cyclone separating piece can be effectively prevented from being rewound by the airflow, so that the cyclone separating effect is further improved.

Moreover, in addition to the dust primarily separated in the cyclone chamber 1101 being discharged into the dust collecting chamber 1102 through the dust discharge port 2201, the dust secondarily separated in the cyclone separator may also be discharged into the dust collecting chamber 1102 through the second through hole 2121, that is, the dust separated in the dust cup assembly 100 may be accumulated in the dust collecting chamber 1102, so that the user may pour out all the dust by opening the dust collecting chamber 1102, thereby being very convenient to use.

Here, it should be noted that in the present embodiment, it is required that the inside of the cyclone separator has a place where the airflow can be provided for the cyclone separation, for example, the inside of the cyclone separator may have a cylindrical cavity, and the external shape thereof is not required. Preferably, as described above, when the cyclonic separating apparatus is a cyclone cone 21, there is a location within it which provides cyclonic separation of the airflow. Next, the cyclone separator will be described as an example of the cyclone cone 21.

Specifically, referring to fig. 8 and 9, a first through hole 2111 may be formed on a peripheral wall surface 211 of the cyclone cone 21 for defining the cyclone chamber 1101. Therefore, the first through hole 2111 is simple and convenient to process, has small through-flow resistance and good through-flow effect, and enables airflow subjected to primary cyclone separation in the cyclone cavity 1101 to smoothly and quickly enter the cyclone cone 21 for secondary cyclone separation, so that the dust removal effect and the dust removal efficiency are further improved.

The peripheral wall 211 of the cyclone cone 21 defining the cyclone chamber 1101 may include a first region and a second region which are continuous, that is, when the first region is divided into a plurality of first sub-regions, the plurality of first sub-regions are non-discretely distributed, and when the second region is divided into a plurality of second sub-regions, the plurality of second sub-regions are non-discretely distributed. In the flow direction of the airflow in the cyclone chamber 1101, the first region is located on the side of the second region far from the dust discharge port 2201, that is, after the airflow enters the cyclone chamber 1101, the airflow passes through the first region, then passes through the second region, and then reaches the dust discharge port 2201. Preferably, the first through holes 2111 are plural and are all located in the first region, that is, the plural first through holes 2111 are all accumulated in the first region and are located on the upstream side of the second region.

From this, the position overall arrangement of first through-hole 2111 accords with cyclone's principle more for the air current of separating can be more, better, more in time, less resistance gets into in cyclone cone 21 through first through-hole 2111, and make the dirt of separating can be better, discharge from dust exhaust port 2201 more fully, thereby not only improved the efficiency and the effect of separation gas, but also can avoid the air current of separating to curl up the dirt of separating once more, and then the phase change has improved separation effect and separation efficiency, with the dust removal effect of further improvement dirt cup subassembly 100.

Preferably, the area of the first region is larger than the area of the second region. Therefore, more and more densely arranged first through holes 2111 can be arranged, so that separated airflow can enter the cyclone cone 21 through the first through holes 2111 more, better, more timely and less in resistance, and the cyclone separation effect is further improved.

Further, referring to fig. 8 and 9, a second through hole 2121 may be formed on the bottom end wall surface 212 of the cyclone cone 21 for defining the dust collecting chamber 1102. Therefore, the second through holes 2121 are easy to machine, the through-flow resistance is small, the through-flow effect is good, dust separated by secondary cyclone in the cyclone cone 21 can smoothly and quickly enter the dust collection cavity 1102 under the action of gravity, the dust removal effect and the dust removal efficiency can be further improved, and the energy consumption can be reduced.

In addition, it should be noted that when the cyclone is not the cyclone cone 21, the specific arrangement positions of the first through holes 2111 and the second through holes 2121 can be adjusted according to the specific situation of the scheme. For example, when the cyclone separating member has a "multi-cone structure" as described above, the first through holes may be plural and formed on the outer circumferential surface of each of the tapered cones defining the cyclone chamber 1101, the tip portion of each of the tapered cones may extend downward into the dust collecting chamber 1102, and the bottom end of the tip portion may be cut open to serve as a second through hole communicating between the inside of each of the tapered cones and the dust collecting chamber 1102, so that the airflow once separated in the cyclone chamber 1101 may enter the plurality of tapered cones through holes for secondary cyclone separation, and the dust matter cyclone separated in each of the tapered cones may be discharged into the dust collecting chamber 1102 through the second through hole at the bottom of the corresponding tapered cone, to reliably perform secondary cyclone separation.

Specifically, under the action of the cyclone centrifugal force, the dust with larger particles can be separated in the cyclone chamber 1101 and can move along the outer peripheral wall of the cyclone cone 21 to the dust discharge port 2201 to be discharged into the dust collection chamber 1102 through the dust discharge port 2201, while the dust with smaller particles can be sucked into the cyclone cone 21 through the first through hole 2111 along with the air flow to be separated again in a cyclone manner, and the fine dust separated in the cyclone cone 21 is discharged into the dust collection chamber 1102 through the second through hole 2121 under the action of gravity. Therefore, two kinds of cyclone separation air channels, namely a large-particle dust cyclone separation air channel outside the cyclone cone 21 and a small-particle dust cyclone separation channel inside the cyclone cone 21, are formed in the dust cup assembly 100, so that the cyclone separation effect and efficiency can be further improved.

In some embodiments of the present invention, referring to fig. 3 and 4, the partition 22 may have an inlet 2202 for supplying gas into the cyclone chamber 1101, that is, the gas flow to be cleaned may enter the cyclone chamber 1101 through the inlet 2202 on the partition 22, thereby achieving easy and convenient processing. Of course, the present invention is not limited thereto, and the air inlet 2202 may not be formed on the partition 22, and in this case, the air to be cleaned may enter the cyclone chamber 1101 from other positions, for example, the air inlet 2202 may be formed on a wall surface of the cup housing 11 defining the cyclone chamber 1101.

In some embodiments of the present invention, referring to fig. 3 and 4, the dirt cup assembly 100 further includes a flow splitter 101, at least a portion of the flow splitter 101 being located within the cyclone chamber 1101 and being sandwiched between an inner annular surface and an outer annular surface of the cyclone chamber 1101, and the portion being simultaneously intercepted between the air inlet 2202 and the dirt discharge port 2201, such that an air flow flowing from the air inlet 2202 into the cyclone chamber 1101 annularly circulates towards the dirt discharge port 2201 in a direction away from the flow splitter 101 (as shown by arrow flow direction B, C in fig. 3). Thus, by providing the flow splitter 101 intercepted between the air inlet 2202 and the air outlet in the cyclone chamber 1101, it is ensured that the airflow entering the cyclone chamber 1101 from the air inlet 2202 flows only in the same direction (as shown by the arrow flow direction B, C in fig. 3), i.e., in a direction away from the flow splitter 101, for cyclone separation, thereby effectively improving the cyclone separation effect.

In addition, by arranging the flow divider 101, the dust exhaust port 2201 can be arranged close to the air inlet 2202, so that the cyclone separation path of the air flow from the air inlet 2202 to the dust exhaust port 2201 is effectively prolonged, and the cyclone separation effect is more sufficient and better. Of course, the present invention is not so limited and in other embodiments of the present invention, the dirt cup assembly 100 may also not include the flow splitter 101, for example, where the dirt discharge port 2201 and the air inlet 2202 may be located remotely, and more specifically, the air inlet 2202 and the dirt discharge port 2201 may be located diametrically opposite to each other about the cyclone cone 21.

Referring to fig. 2 and 4, in a specific example of the present invention, the flow divider 101 may include a diversion rib 26 and a partition rib 121 that are abutted up and down, that is, the diversion rib 26 is located above the partition rib 121, the partition rib 121 is located below the diversion rib 26, and a lower end of the diversion rib 26 is opposite to and abutted against an upper end of the partition rib 121. Therefore, the flow divider 101 is ingenious in structure and can be simply realized. Here, "the a member and the B member abut" means that the a member applies a thrust to the B member, the B member applies a thrust to the a member, and the points of action of the applied thrust are the same.

Preferably, the diversion rib 26 and the cyclone cone 21 are an integral piece (i.e. the diversion rib 26 and the cyclone cone 21 are not detachable, for example, they may be an integral injection molding), and the partition rib 121 and the cup shell 11 are an integral piece (i.e. the partition rib 121 and the cup shell 11 are not detachable, for example, they may be an integral injection molding). Therefore, after the cyclone cone 21 is installed in the cup shell 11, the diversion rib 26 naturally offsets with the partition rib 121 to form the flow divider 101, so that the flow divider 101 is easily realized. In addition, through the butt joint and abutting cooperation of the partition ribs 121 and the diversion ribs 26, the assembly of the cyclone cone 21 and the cup shell 11 can be effectively positioned, the structural complexity and the assembly difficulty of the dust cup assembly 100 are reduced, the structure of the dust cup assembly 100 is simpler, the processing and the manufacturing are more convenient, the assembly efficiency is improved, and the production cost is reduced.

In a preferred embodiment of the invention, the portion of the splitter 101 located within the cyclone chamber 1101 tapers in width in the circumferential direction of the cyclone chamber 1101 in a direction from the cyclone chamber 1101 to the dirt collection chamber 1102, for example in a direction from top to bottom as viewed in FIG. 2. For example, in one specific example of the present invention, referring to fig. 3 and 4 in combination with fig. 9, the flow guiding ribs 26 are sandwiched between the inner annular surface and the outer annular surface of the cyclone chamber 1101 and extend downward from the upper end surface 1201 of the cyclone chamber 1101, and the width (for example, H shown in fig. 9) of the flow guiding ribs 26 in the circumferential direction of the cyclone chamber 1101 is gradually reduced along the direction from top to bottom. Thus, two side walls of the splitter 101 in the circumferential direction of the cyclone chamber 1101 (for example, the left side wall and the right side wall of the splitter 101 shown in fig. 2) are more suitable for guiding the flow, one of the side walls (for example, the right side wall of the splitter 101 shown in fig. 2) can make the airflow entering the cyclone chamber 1101 from the air inlet 2202 better circulate along the cyclone chamber 1101 (as shown by the arrow flowing direction C in fig. 3), and the other side wall (for example, the left side wall of the splitter 101 shown in fig. 2) can make the dust separated in the cyclone chamber 1101 better discharged through the dust outlet 2201 (as shown by the arrow flowing direction D in fig. 4), so as to further improve the cyclone separation effect.

In a preferred embodiment of the present invention, referring to FIGS. 2 and 3, a side surface (e.g., a right side surface as viewed in FIG. 2) of the splitter 101 adjacent to the air inlet 2202 is configured as a streamlined curved surface that guides the airflow from the air inlet 2202 into the cyclone chamber 1101 smoothly. For example, in a specific example of the present invention, a side surface (e.g., a right side surface shown in fig. 2) of the flow guiding rib 26 adjacent to the air inlet 2202 is smoothly and transitionally connected with a side surface (e.g., a right side surface shown in fig. 2) of the blocking rib 121 adjacent to the air inlet 2202, and the side surface (e.g., the right side surface shown in fig. 2) of the flow guiding rib 26 adjacent to the air inlet 2202 and the side surface (e.g., the right side surface shown in fig. 2) of the blocking rib 121 adjacent to the air inlet 2202 together form a streamline curved surface guiding the airflow to smoothly flow from the air inlet 2202 to the cyclone chamber 1101. Therefore, the air inlet resistance can be reduced, the energy consumption is reduced, the air inlet efficiency is improved, and the dust removal efficiency is improved.

More specifically, a side surface (e.g., a right side surface as viewed in fig. 2) of the flow guide rib 26 near the air inlet 2202 is configured as a first flow guide curved surface 261 that is concave toward a direction away from the dust collection chamber 1102 and a direction near the dust discharge port 2201 (e.g., an upper left direction as viewed in fig. 2). Therefore, the air inlet resistance can be further reduced, the energy consumption is reduced, the air inlet efficiency is improved, and the dust removal efficiency is improved.

In a preferred embodiment of the present invention, referring to fig. 2 and 4, a side surface (e.g., a left side surface as viewed in fig. 2) of the flow splitter 101 adjacent to the dust discharge port 2201 is configured as a streamlined curved surface guiding the airflow smoothly flowing out from the cyclone chamber 1101 to the dust discharge port 2201. For example, in a specific example of the present invention, a side surface (for example, the left side surface shown in fig. 2) of the flow guide rib 26 adjacent to the dust discharge port 2201 is smoothly and transitionally connected with a side surface (for example, the left side surface shown in fig. 2) of the partition rib 121 adjacent to the dust discharge port 2201, and the side surface (for example, the left side surface shown in fig. 2) of the flow guide rib 26 adjacent to the dust discharge port 2201 and the side surface (for example, the left side surface shown in fig. 2) of the partition rib 121 adjacent to the dust discharge port 2201 together form a streamline curved surface guiding the airflow to smoothly flow out from the cyclone chamber 1101 to the dust discharge port 2201. Therefore, the air inlet resistance can be reduced, the energy consumption is reduced, the air inlet efficiency is improved, and the dust removal efficiency is improved.

More specifically, a side surface (e.g., a left side surface as viewed in fig. 2) of the flow guide rib 26 near the dust discharge port 2201 is configured as the second flow guide curved surface 262 recessed toward a direction away from the dust collecting chamber 1102 and toward a direction near the air inlet 2202 (e.g., an upper right direction as viewed in fig. 2). Therefore, the air inlet resistance can be further reduced, the energy consumption is reduced, the air inlet efficiency is improved, and the dust removal efficiency is improved.

Here, it should be noted that the concept of "streamline curved surface" is well known to those skilled in the art, and specifically, "streamline curved surface" refers to: usually present as a smooth and regular surface, without large undulations and sharp corners, the flow is predominantly laminar over a streamlined surface, with little or no turbulence, to ensure that both the surface and the flow experience less resistance.

Preferably, with reference to fig. 4 and 8, the divider 22 has perforations 220 thereon. For example, in one specific example of the present invention, a portion may be cut out of the partitioning member 22 in a closed loop plate shape to change the partitioning member 22 into a C-shaped plate shape, and at this time, a through hole 220 may be defined between two side walls (simply referred to as a first cut wall 221 and a second cut wall 222) formed on the partitioning member 22 due to the cut-out portion and the outer surface of the cyclone cone 21, and the inner surface of the cup housing 11. Specifically, the through hole 220 and the flow divider 101 jointly define an air inlet 2202 and a dust outlet 2201, that is, a portion of the flow divider 101 extends into the through hole 220 to divide the through hole 220 into the air inlet 2202 and the dust outlet 2201 on both sides of the flow divider 101, and more specifically, the dust outlet 2201 is defined between one side wall surface (for example, a left side wall surface as shown in fig. 2) of the flow divider 101 and the first cut wall 221, and the air inlet 2202 is defined between the other side wall surface (for example, a right side wall surface as shown in fig. 2) of the flow divider 101 and the second cut wall 222.

Of course, the present invention is not limited thereto, and in other embodiments of the present invention, the air inlet 2202 and the dust exhaust port 2201 may be separate holes penetrating the partition 22, for example, two separate holes, i.e. not communicated with each other, may be formed on the partition 22 in the shape of a circular plate, and are the air inlet 2202 and the dust exhaust port 2201, respectively. Here, the description will be given only by taking the case where the air inlet 2202 and the dust outlet 2201 are defined by the through hole 220 and the flow divider 101 together.

For example, in one specific example of the present invention, as shown in fig. 2 and 4, a part (e.g., an upper part) of the partition rib 121 is sandwiched between an inner annular surface and an outer annular surface of the cyclone chamber 1101, an upper end of the partition rib abuts against a lower end of the flow guide rib 26, and the other part (e.g., a lower part) of the partition rib 121 passes through the through hole 220 downward to divide the through hole 220 into the air inlet 2202 and the dust exhaust port 2201 located at two sides of the partition rib 121. Therefore, the cyclone dust collector is extremely convenient to process, the air inlet 2202 and the dust exhaust port 2201 can be ensured to be very close, the cyclone separation path in the cyclone chamber 1101 is prolonged, and the cyclone separation effect is improved.

Of course, the structure of the flow divider is not limited thereto. For example, in other embodiments of the present invention, the splitter may be only disposed on the cyclone cone 21 and the upper end of the splitter may be flush with the upper end surface 1201 of the cyclone chamber 1101, and the lower end of the splitter passes through the through hole 220; as another example, the splitter may also be provided only on the cup 11 and the upper end of the splitter may extend to be flush with the upper end face 1201 of the cyclone chamber 1101. Therefore, the flow dividing piece is convenient to process and assemble. In addition, the splitter 101 may also be a separate component and fixed in the cyclone chamber 1101 by a subsequent assembly means, for example, by the fitting of a slot insert, which is not described herein again.

In a preferred example of the present invention, referring to fig. 6 and 8 in combination with fig. 2, the dirt cup assembly 100 further includes a position-retaining rib 122 and a position-limiting rib 23, wherein the position-retaining rib 122 and the partition rib 121 are both disposed on the cup housing 11 and spaced apart from each other in the circumferential direction of the cyclone chamber 1101, the position-limiting rib 23 and the partition 22 are both disposed on the cyclone cone 21, and the position-limiting rib 23 is disposed in the through hole 220 and abuts against both sides of the position-retaining rib 122 and the position-retaining rib 121 together with one circumferential side wall (e.g., the second cut wall 222 shown in fig. 2) of the through hole 220.

Specifically, the stopper rib 23 may extend from the first cut wall 221 in a direction toward the second cut wall 222 along the peripheral wall surface 211 of the cyclone cone 21, one end of the stopper rib 23 away from the first cut wall 221 may abut against one side surface of the blocking rib 121 away from the blocking rib 122 (e.g., on the left side surface of the blocking rib 121 shown in fig. 2), and the second cut wall 222 may abut against one side surface of the blocking rib 122 away from the blocking rib 121 (e.g., on the right side surface of the blocking rib 122 shown in fig. 2). Thus, the cyclone cone 21 can be stably and reliably assembled with the cup housing 11 by the engagement of the spacer 22, the stopper rib 23, the detent rib 122, and the partition rib 121.

Preferably, the separating member 22 and the clamping rib 122 are both integrated with the cyclone cone 21 to form the cyclone cone assembly 2, and the separating rib 121, the clamping rib 122 and the cup shell 11 are integrated to form the cup shell assembly 1, so that the processing is convenient, and the assembly reliability is higher.

Preferably, as shown in fig. 2, the blocking rib 121 extends obliquely toward a direction away from the catching rib 122, and the catching rib 122 extends obliquely toward a direction away from the blocking rib 121 in a direction from the cyclone chamber 1101 to the dust collection chamber 1102. For example, in the example shown in fig. 1, the blocking rib 121 and the locking rib 122 are spaced apart in the left-right direction, and the blocking rib 121 is located on the left side of the locking rib 122, wherein the blocking rib 121 extends obliquely from top to bottom toward the left-lower direction, and the locking rib 122 extends obliquely from top to bottom toward the right-lower direction, so that the distance between the blocking rib 121 and the locking rib 122 can be gradually increased in the top-down direction. From this, at the in-process of assembly whirlwind awl subassembly 2 and cup shell subassembly 1, cut off muscle 121 and screens muscle 122 and can play the guide effect that slides for spacing muscle 23 can slide downwards along cutting off muscle 121, and/or, make the second cut wall 222 can slide downwards along screens muscle 122, thereby make whirlwind awl subassembly 2 and cup shell subassembly 1 can assemble in place simply and rapidly.

Further, the bottom of the limiting rib 23 is provided with a first guide block 24 which is located at the air inlet 2202 and is in sliding guiding fit with the blocking rib 121, one side surface of the first guide block 24 close to the blocking rib 121 extends obliquely from top to bottom towards the direction away from the blocking rib 121, for example, in the example shown in fig. 2 and 7, the first guide block 24 is arranged at the bottom of the limiting rib 23 and is located on the left side of the blocking rib 121, and the right side wall of the first guide block 24 extends obliquely towards the lower left side along the direction from top to bottom. Therefore, in the process of assembling the cyclone cone component 2 and the cup shell component 1, the first guide block 24 can smoothly slide down along the partition rib 121 and can adaptively rotate, so that the cyclone cone component 2 and the cup shell component 1 can be conveniently and rapidly assembled in place.

Further, the bottom of the partitioning member 22 has a second guide block 25 located at the air inlet 2202 and slidably and guide-engaged with the position-locking rib 122, and a side surface of the second guide block 25 close to the position-locking rib 122 is inclined and extended from top to bottom in a direction away from the position-locking rib 122, for example, in the example shown in fig. 2 and 7, the second guide block 25 is provided at the bottom of the partitioning member 22 and located on the right side of the position-locking rib 122, and a left side wall of the second guide block 25 is inclined and extended toward the lower right in the direction from top to bottom. Therefore, in the process of assembling the cyclone cone assembly 2 and the cup shell assembly 1, the second guide block 25 can adaptively rotate along the clamping rib 122, so that the cyclone cone assembly 2 and the cup shell assembly 1 are conveniently and rapidly assembled in place.

Specifically, when the cyclone cone assembly 2 and the cup shell assembly 1 are installed in place, the cyclone cone 21 can slightly rotate relative to the cup shell 11 to eliminate small installation dislocation under the guiding action of the first guide block 24 and the second guide block 25 and push the cyclone cone 21 downwards, so that the cyclone cone assembly 2 and the cup shell assembly 1 are completely matched in place, and the relative setting angle meets the design requirement.

Here, it should be noted that, because the cyclone cone assembly 2 and the cup shell assembly 1 can both be plastic parts with certain elasticity, and the shape of the cup shell assembly 1 can be irregular, thereby in the process of installing the cyclone cone assembly 2 and the cup shell assembly 1, the problem of installation dislocation can be generated, through the guide cooperation of the first guide block 24 and the partition rib 121 and the cooperation of the second guide block 25 and the clamping rib 122, the tiny installation dislocation can be effectively eliminated, the installation efficiency is improved, in short, through the arrangement of the first guide block 24 and the second guide block 25, the problem of inaccurate relative setting angle between the cyclone cone assembly 2 and the cup shell assembly 1 can be effectively avoided, the cyclone cone assembly 2 and the cup shell assembly 1 can be assembled in place, and the assembly efficiency and the assembly success rate are improved.

In some embodiments of the present invention, referring to FIGS. 2 and 3, the cup 11 has a flow-inducing path 120 therein, and both ends of the flow-inducing path 120 communicate with the interior of the cyclone chamber 1101 and the exterior of the cup 11, respectively, to induce the airflow outside the cup 11 into the cyclone chamber 1101. Therefore, by arranging the flow guide channel 120 in the cup shell 11, the flow direction of the dust and air can be adjusted in advance through the flow guide channel 120 and then enter the cyclone chamber 1101, so that the energy loss of the dust and air entering the cyclone chamber 1101 is effectively reduced, the energy consumption is reduced, and the cleaning efficiency is improved.

For example, in some embodiments of the present invention, the flow-inducing channel 120 may be located in the dust collection chamber 1102 and/or the cyclone chamber 1101, and preferably, the flow-inducing channel 120 is located in the dust collection chamber 1102, so as to avoid the problem that the flow-inducing channel 120 occupies the space in the cyclone chamber 1101, ensure that the cyclone chamber 1101 has enough cyclone separation space, and improve the cyclone separation effect.

In some embodiments of the present invention, referring to fig. 2, 3 and 5, the dirt cup assembly 100 further comprises: drain tube 12, and a drain channel 120 is defined within drain tube 12. Thus, by providing a drain tube 12 that defines a drain channel 120, the configuration of the drain channel 120 is facilitated, improving the ease of implementation of the dirt cup assembly 100. Preferably, draft tube 12 is a unitary piece with cup housing 11, e.g., draft tube 12 is an integral injection molded piece with cup housing 11, thereby facilitating manufacturing and simplifying assembly and providing a reliable installation of draft tube 12.

Specifically, when the partition 22 has an air inlet 2202 thereon, and when the drainage passage 120 is located in the dust collecting chamber 1102, the drainage tube 12 may be disposed in the dust collecting chamber 1102, at which time one end (e.g., an upper end shown in fig. 2) of the drainage tube 12 communicates with the inside of the cyclone chamber 1101 through the air inlet 2202 and the other end (e.g., a lower end shown in fig. 2) of the drainage tube 12 communicates with the outside of the cup housing 11, so that the drainage tube 12 may introduce the airflow outside the cup housing 11 into the cyclone chamber 1101. In addition, it should be noted that, for the convenience of connection, the dust cup assembly 100 may further include an air inlet pipe 13, and the air inlet pipe 13 may be located outside the cup shell 11 and communicated with the drainage tube 12, which is not described herein again.

Further, a partial end surface of one end of the draft tube 12 is stopped against an end wall surface of the cyclone cone 21 for defining the dust collecting chamber 1102. For example, in the example shown in FIG. 3, the portion of upper end surface 1201 of draft tube 12 connected to inlet port 2202, which is close to the central axis of cup 11, abuts against bottom end wall surface 212 of cyclone cone 21. Therefore, when the drainage tube 12 is fixed on the cup shell 11, the drainage tube 12 can play a role in positioning the cyclone cone 21, and the reliability of relative positioning between the cyclone cone 21 and the cup shell 11 is ensured.

Preferably, the partition rib 121 and the blocking rib 122 may be formed by extending the upper end surface 1201 of the drainage tube 12 connected to the air inlet 2202 toward the direction of the cyclone chamber 1101, so that the upper end of the drainage tube 12 can be tightly communicated with the air inlet 2202 through the cooperation with the partition rib 121, the blocking rib 122, the cup shell 11 and the cyclone cone 21, thereby ensuring reliable drainage effect and convenient processing.

Here, it should be noted that the structural forms of the partition rib 121, the blocking rib 122, the first guide block 24 and the second guide block 25 may be as described above, but the present invention is not limited thereto, and the structural forms of the partition rib 121, the blocking rib 122, the first guide block 24 and the second guide block 25 may be adaptively adjusted and changed according to different specific embodiments. For example, the first guide block 24 may be provided on the top of the stopper rib 23, and the second guide block 25 may be provided on the top of the partitioning member 22.

In addition, the structure of the separating member is not limited to the annular plate, for example, in other embodiments of the present invention, the separating member may further include an annular flat plate and a sleeve, wherein the sleeve may be sleeved outside the cyclone separating member, and the annular flat plate may be sleeved between the sleeve and the cup housing 11, so that an annular cyclone chamber may be defined between the sleeve, the cup housing 11 and one side surface of the annular flat plate. In contrast to the embodiments shown in fig. 1-9, the axial height of the cyclone chamber may be greater than the axial height of the cyclonic separating member, since the cyclone chamber is directly surrounded outside the sleeve to indirectly surround the cyclonic separating member.

In addition, the structure of the cyclone separating member is not limited to the cyclone cone 21, for example, in other embodiments of the present invention, the cyclone separating member may also be the above-mentioned "multi-cone structure" (not shown), and the separating member 22 may be sleeved on the outer circumferential surface of the whole multi-cone structure (i.e. not on the outer circumferential surface of each pointed conical cylinder respectively).

In the following, a hand-held cleaner according to an embodiment of the second aspect of the present invention will be briefly described.

A hand-held cleaner in accordance with an embodiment of the second aspect of the invention includes a dirt cup assembly 100 in accordance with the above-described embodiment of the first aspect of the invention. Other constructions of the hand-held cleaner according to embodiments of the invention, such as the body, floor brush, etc., and operation are known to those of ordinary skill in the art and will not be described in detail herein.
