In addition, the skilled in the art can combine and combine the different embodiments or examples described in the present application and the features of the different embodiments or examples without contradiction.

[0049] The present application is combined with Figures 1 to 10 The dust collection assembly and the dust collector are described. When the dust collection assembly is described, it is described in combination with the handheld dust collector. It can be understood that the dust collection assembly can also be applied to devices such as barrel-type dust collectors, central dust collectors, stand-type dust collectors or intelligent sweeping robots, which are not illustrated one by one here.

[0050] Please refer to Figures 1 to 4 The dust collection assembly according to the embodiments of the present application includes a dust collection component 100. It should be noted that in addition to including the dust collection component 100, the dust collection assembly can also include the cup seat 200 and the cup body 300 mentioned later (refer to Figure 1 ), of course, the dust collection assembly can only include the dust collection component 100, at this time the dust collection assembly and the dust collection component 100 refer to the same. Refer to Figures 2 to 4The dust collecting component 100 is provided with an air inlet 101 and an air outlet 102. The air inlet 101 is connected to the air supply duct in the vacuum cleaner body 400, and the air outlet 102 is connected to the exhaust duct of the vacuum cleaner body 400. The specific settings of the air supply duct and the exhaust duct are not limited. They can refer to any vacuum cleaner disclosed in the prior art and can be adaptively adjusted based on the dust collecting components in the previous embodiment. The dust collecting component 100 includes a accommodating component 103 and a first filter component 104 located in the accommodating component 103. An annular vortex space 107 is formed between the accommodating component 103 and the first filter component 104. The annular vortex space 107 is connected to the air inlet 101, and the air outlet 102 is formed at the end of the first filter component 104 along the airflow direction.

[0051] Among them, the air flow enters the air inlet 101 through the air supply duct, and enters the annular vortex space 107 through the air inlet 101. The air flow in the annular vortex space 107 carries the dust and continues to move toward the first filter component 104. After being filtered by the first filter component 104, the air flow finally flows from the air outlet 102 to the exhaust duct. During the movement, the dust collides with the first filter component 104 or the receiving component 103 and falls into the annular vortex space 107. Obviously, the inner surface of the receiving component 103 and the first filter component 104 can fully intercept the dust, thereby preventing the first filter component 104 or the air outlet 102 from being blocked. It should be noted that the cross-section of the annular vortex space 107 here can be a standard ring, such as a circular ring or a polygonal ring, or an irregular ring. The cross-section here is also a cross-section perpendicular to the central axis of the annular vortex space.

[0052] According to the dust collecting component 100 of the embodiment of the present application, an annular cyclone space 107 is formed between the receiving component 103 and the first filter component 104. After the airflow enters the annular cyclone space through the air inlet 101, it will perform a spiral motion or a quasi-spiral motion along the annular cyclone space 107, thereby separating the dust from the air within the annular cyclone space 107. Taking a vacuum cleaner as an example, even if the vacuum cleaner does not additionally include a multi-cone cyclone structure, the dust collecting capacity of the dust collecting component and the dust removal effect of the vacuum cleaner can still be maintained.

[0053] According to the embodiments of this application, see Figure 2The dust collecting component 100 includes a first support component 105 and a second support component 106 arranged opposite to each other, and the accommodating component 103 and the first filter component 104 are both flexible components, and the accommodating component 103 and the first filter component 104 are both connected between the first support component 105 and the second support component 106. In this case, since the accommodating component 103 and the first filter component 104 are flexible components, the entire dust collecting component 100 can be folded, and when the dust collecting component 100 is not in use, its placement space can be saved. When the dust collecting component 100 is needed, the first support component 105 and the second support component 106 can fix the shape of the dust collecting component 100 when it is opened to ensure that the dust collecting component 100 has enough space to collect dust. Alternatively, the accommodating component 103 and the first filter component 104 can also be configured in a foldable structure, and then the accommodating component 103 or the first filter component 104 can be folded to achieve the purpose of folding, and the accommodating component 103 or the first filter component 104 can be unfolded to form an annular vortex space 107.

[0054] According to an embodiment of the present application, the container 103 may be a dust bag. The dust bag may be a plastic bag, a cloth bag, or a bag made of other soft materials, as long as it is easily folded up. Similarly, the first filter component 104 may be a HEPA (High Efficiency Particulate Air) filter, which can also be folded up together with the container 103 to save storage space when the dust collection component 100 is not in use.

[0055] When storage space is not a concern, the container 103 and the first filter 104 of the dust collecting unit 100 can also be made of hard materials. For example, the container 103 can be made of plastic or cardboard, and the first filter 104 can be made of filter carbon or filter foam. In this case, the first support member 105 and the second support member 106 are not required to define the annular vortex space 107.

[0056] Furthermore, when the dust collecting component 100 is a disposable consumable, the cost of the dust collecting component 100 can be a key consideration. The container 103 and the first filter component 104 can be made of low-cost materials, such as a plastic bag for the container 103 and a HEPA filter or filter bag for the first filter component 104. Similarly, the first support component 105 and the second support component 106 can also be made of both low cost and high support strength, such as cardboard or foam. Of course, the dust collecting component 100 can also be reused multiple times.

[0057] According to an embodiment of the present application, at least one of the first support member 105 and the second support member 106 is provided with an air inlet 101. Since the first support member 105 and the second support member 106 have a certain structural strength, when the air inlet 101 is provided on the first support member 105 or the second support member 106, the reliability of the connection between the air inlet 101 and the air supply duct can be ensured.

[0058] According to the embodiments of the present application, Figure 4 The air inlet direction of air inlet 101 is tangential to annular vortex space 107, directing the airflow into annular vortex space 107 along the inner surface of containment member 103. When annular vortex space 107 has a rectangular cross-section, the tangential direction corresponds to the length of the corresponding side of air inlet 101. This prevents significant wind resistance at air inlet 101 and ensures sufficient airflow into annular vortex space 107.

[0059] See Figure 4 A baffle 108 is provided at the air inlet 101 to prevent dust from escaping. The baffle 108 prevents dust from being discharged from the air inlet 101 to the outside of the dust collecting unit 100, thereby ensuring the dust collection effect of the dust collecting unit 100. Even when the dust collecting unit 100 has completed its work and is detached from the vacuum cleaner, dust is not likely to escape.

[0060] According to the embodiments of this application, reference Figures 5 to 7 The dust collection assembly further includes a cup holder 200. The cup holder 200 is formed with a mounting position 201 for the dust collection component 100. The cup holder 200 is provided with a second filter component 202 and a first guide channel 203. The second filter component 202 is located in the first guide channel 203, and the first guide channel 203 is connected to the air outlet 102. The provision of the cup holder 200 facilitates the assembly and disassembly of the dust collection component 100.

[0061] According to an embodiment of the present application, the cup holder 200 is provided with a support rod 204. The support rod 204 extends along the central axis of the annular vortex space 107. The support rod 204 is used to open the dust collecting component 100. In other words, by providing the support rod 204 on the cup holder 200, the dust collecting component 100 can be automatically opened, which is convenient for use. Specifically, when the dust collecting component 100 is installed in the cup holder 200, the support rod 204 extends into the first filter component 104, thereby driving the second support component 106 to move away from the first support component 105, causing the accommodating component 103 and the second filter component 202 to expand.

[0062] The second filter component 202 is provided with a grille portion, which is positioned corresponding to the air outlet 102 to further filter the airflow entering the cup holder 200 from the air outlet 102. If the cup holder 200 is provided with a support rod 204, the support rod 204 can be connected to the grille portion. Furthermore, a filter hole is provided at the end of the first guide channel 203 to further prevent clogging.

[0063] According to the embodiments of this application, see Figures 8 to 10 The dust collecting assembly also includes a cup body 300, which is detachably mounted on the cup holder 200. The cup body 300 is provided with a accommodating cavity 301 and a second guide channel 302. The dust collecting component 100 is mounted in the accommodating cavity 301, and the second guide channel 302 is connected to the air inlet 101. By providing the cup body 300, the structural reliability of the dust collecting component 100 can be improved. Specifically, during operation, the dust collecting component 100 is mounted to the cup body 300, and the cup body 300 is mounted to the cup holder 200. At this time, the dust collecting component 100 is located between the cup body 300 and the cup holder 200, and the cup body 300 and the cup holder 200 can protect the dust collecting component 100 to prevent the possibility of dust leakage. When the vacuum cleaner is finished working, the cup body 300 is removed from the cup holder 200, and the dust collecting component 100 can be directly poured out of the cup body 300.

[0064] Combine Figure 9 For a vacuum cleaner, when the cup body 300 is installed to the vacuum cleaner, the opening of the accommodating cavity 301 faces downward, the first support component 105 is located below the second support component 106, and the air inlet 101 is arranged on the first support component 105. At this time, after the air flow passes through the air inlet 101 and enters the annular vortex space 107, it can more fully contact the first filter component 104 and extend the extension path of the air flow.

[0065] Combine Figure 9 The inner wall of the cup body 300 is provided with a positioning portion 303, and the dust collecting component 100 is provided with an abutting portion 1051 corresponding to the positioning portion 303, and the abutting portion 1051 is formed with an air inlet 101. Therefore, when the dust collecting component 100 is installed, the dust collecting component 100 can be quickly installed and positioned by the cooperation between the abutting portion 1051 and the positioning portion 303. Specifically, when the dust collecting component 100 includes a first support component 105 and a second support component 106, the first support component 105 is formed with the abutting portion 1051. After the dust collecting component 100 is installed in the accommodating cavity 301 of the cup body 300, the cup body 300 is inverted so that the opening of the accommodating cavity 301 faces downward, and on this basis, the cup body 300 is fixed to the cup holder 200. Of course, the cup body 300 and the cup holder 200 can also be fixedly connected first, and then the cup body 300 and the cup holder 200 are installed together to the vacuum cleaner body 400.

[0066] According to the embodiments of the present application, Figure 9 , the side wall of the cup body 300 is provided with a second guide channel 302, and the outlet end of the second guide channel 302 is provided with a sealing ring 304, and the abutting portion 1051 is sealed and connected to the second guide channel 302 through the sealing ring 304. In this case, since the second guide channel 302 is provided on the side wall of the cup body 300, there is no need to additionally provide a guide tube, which can reduce the difficulty of preparation and assembly. And by providing a sealing ring 304 at the outlet end of the second guide channel 302, when the abutting portion 1051 and the cup body 300 are fixed, it is possible to prevent the airflow from passing through the gap between the dust collecting component 100 and the cup body 300 and entering the accommodating cavity 301 of the cup body 300.

[0067] According to an embodiment of the present application, when the cup holder 200 is provided with a second guide channel 302, the second guide channel 302 and the abutment portion 1051 can also serve as fool-proof components to ensure that the dust collecting component 100 is quickly and accurately installed in the accommodating cavity 301 of the cup body 300.

[0068] According to an embodiment of the present application, the positioning portion 303 and the abutting portion 1051 are both annular. In this case, the inner walls of the dust collecting component 100 and the cup body 300 overlap, thereby better ensuring that the airflow enters the containing component 103 through the air inlet 101, and preventing the airflow from entering between the containing component 103 and the cup body 300 of the dust collecting component 100. Among them, the positioning portion 303 and the abutting portion 1051 can be made of elastic material, or a sealing member 307 with a certain elasticity can be provided between the positioning portion 303 and the abutting portion 1051 to ensure sealed contact between the dust collecting component 100 and the inner wall of the cup body 300.

[0069] According to an embodiment of the present application, both the container 103 and the cup 300 are transparent. In this case, the vortex within the container 103 can be directly observed, achieving a visual cyclonic separation effect. When the dust in the annular vortex space 107 reaches a certain amount, the user can promptly replace the dust collection component 100 to prevent the dust in the dust collection component 100 from entering the vacuum cleaner body 400.

[0070] According to the embodiments of the present application, Figure 8, the cup body 300 and the cup holder 200 are connected by a buckle 305. In this case, the dust collecting component 100 is first installed in the cup body 300. Of course, there is a certain pre-tightening force between the dust collecting component 100 and the cup body 300 to prevent the dust collecting component 100 from slipping out of the cup body 300. On this basis, the cup body 300 is turned upside down to the cup holder 200. At this time, the edge of the cup body 300 is pressed against the cup holder 200, and a seal 307 is provided between the cup body 300 and the cup holder 200 to form an enclosed space between the cup body 300 and the cup holder 200. In order to improve the elasticity of the seal 307, the cross-section of the seal 307 can adopt a special-shaped structure. In order to ensure reliable installation between the cup body 300 and the cup holder 200, a buckle 305 is provided on the cup holder 200 or the cup body 300, and then the cup body 300 is locked or unlocked by rotating the buckle 305. Of course, the connection method between the cup holder 200 and the cup body 300 is not limited to the examples given here. For example, the cup holder 200 and the cup body 300 can also be connected by a spiral connection, or by an interference fit.

[0071] According to an embodiment of the present application, when the cup holder 200 and the cup body 300 are connected using a buckle 305, the number of buckles 305 can be multiple and spaced apart along the circumference of the cup holder 200. In this case, the cup body 300 is provided with a circumferential slot that mates with the buckle 305, and the slot is provided with a snap-fitting protrusion that engages with the buckle 305. To ensure the structural strength of the cup body 300, an annular reinforcing rib 308 is provided corresponding to the slot.

[0072] According to one embodiment of the present application, when the dust needs to be poured out, the disposable dust collecting component 100 can be poured out directly from the cup body 300. At this time, there is no need to clean the cup body 300, and the hands do not need to touch the dust collecting component 100. Of course, in order to ensure that the dust collecting component 100 falls off from the cup body 300, a ejection component (not shown in the figure) can also be set at the bottom of the accommodating cavity 301 of the cup body 300, and then the ejection component can be pressed to prevent the dust collecting component 100 from being stuck in the accommodating cavity 301. And because the user only needs to discard the dust collecting component 100, secondary pollution will not be caused. Of course, when the cup body 300 is not set, but only the cup holder 200 is set, the dust collecting component 100 is directly connected to the cup holder 200, and then when the user needs to pour out the dust, there is no need to open the cup body 300, and the operation at this time is more convenient. The following table can be used to compare the effects of the dust collecting component of the present application and the original dust cup:

[0073] Indicator name Dust cup Dust collection assembly Is there secondary pollution when dust is poured out Yes No Is it necessary to clean the dust cup Yes No Filtering efficiency 90% 94% Suction force decay 80% 12%

[0074] According to an embodiment of the present application, a vacuum cleaner is provided, comprising a vacuum cleaner body 400 and the dust collecting assembly described above. The vacuum cleaner body 400 is provided with an air supply duct and an air exhaust duct; the air supply duct is connected to the air inlet 101 , and the air exhaust duct is connected to the air outlet 102 .

[0075] Among them, combined Figure 8 and Figure 9 A bayonet 306 is provided on the cup body 300 of the dust collecting assembly. After the dust collecting assembly is installed to the vacuum cleaner body 400, it is fixed by the bayonet 306 and the connecting piece on the vacuum cleaner body 400 to further ensure the installation reliability of the dust collecting assembly.

[0076] Finally, it should be noted that the above embodiments are intended only to illustrate the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art will appreciate that various combinations, modifications, or equivalent substitutions of the technical solutions of the present invention do not depart from the spirit and scope of the technical solutions of the present invention and are intended to be encompassed by the claims of the present invention.
