Description

Technical Field

[0001] The present invention belongs to the technical field of household cleaning equipment, and particularly relates to a device equipped with a cyclone, and more particularly to a multi-cone cyclone cup structure, a vacuum cleaner and a using method thereof. Background Art

[0002] In the field of household cleaning equipment, cyclone separation technology is the core solution for bagless vacuum cleaners.

[0003] In related technologies, for example, a patent with the patent number CN219306606U provides a multi-cone cyclone dust-gas separation vacuum cleaner, which uses a multi-cone cyclone structure to separate particles of different particle sizes, and a filter assembly is arranged at the top of the multi-cone cyclone mechanism to filter particles with a particle size less than 50 μm, so as to avoid the discharged gas containing tiny particles. During actual use, it is found that the suction force of the vacuum cleaner is greatly reduced before the calibrated replacement time of the filter assembly, so the filter assembly in the vacuum cleaner needs to be replaced.

[0004] Therefore, how to reduce the replacement frequency of the filter assembly in the vacuum cleaner is an urgent problem to be solved at present.

[0005] It should be noted that the above information disclosed in this background art part is only used to understand the background art of the concept of this application. Therefore, the above description is not considered as information of the prior art. Summary of the Invention

[0043] In an alternative embodiment, a plurality of air channels communicating the groove with the annular groove are opened inside the bottom cover;

[0044] When opening the cover for the first time, the rubber plug remains inserted into the dust outlet of the dust cup, and a negative pressure is formed when the guide ring is separated from the plug post, so as to adsorb the sealing ring in the annular groove through the air channel.

[0045] In a second aspect, an embodiment of the present disclosure further provides a vacuum cleaner, including:

[0046] An air source and the multi-cone cyclone cup structure as described above;

[0047] The air source is arranged at the top of the multi-cone cyclone cup structure.

[0048] In a third aspect, an embodiment of the present disclosure further provides a method of using a vacuum cleaner applied to the vacuum cleaner as described above,

[0049] When the vacuum cleaner needs to be cleaned, the method of use includes:

[0050] Open the bottom cover to the first-level open state to clean the particles in the dust collection bucket;

[0051] After the particles in the dust collection bucket are cleaned, open the bottom cover to the second-level open state to clean the particles in the dust cup;

[0052] Among them, the particle size of the particles in the dust collection bucket is greater than 200 μm, and the particle size of the particles in the dust cup is between 50 μm and 200 μm.

[0053] The beneficial effect of the present invention is that the multi-cone cyclone cup structure, the vacuum cleaner and its use method adopt a two-stage opening method. When opening the cover for the first stage, the internal dust cup is blocked to complete the cleaning of the particles in the dust collection bucket, and then the cover is opened for the second stage to pull out the rubber plug from the dust cup to complete the cleaning of the particles in the dust collection bucket, thereby avoiding the dust in the dust collection bucket from entering the multi-cone cyclone cup separator through the dust cup when opening the cover, and further avoiding large-particle-size particles from entering the filter assembly, and prolonging the service life of the filter assembly.

Specific embodiments

[0065] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0066] In this document, when it is mentioned that the first component is located on the second component, this may mean that the first component can be directly formed on the second component, or a third component can be inserted between the first component and the second component. In addition, in the drawings, to effectively describe the technical content, the thickness of the components can be exaggerated or reduced.

[0067] In this document, when an element or layer is referred to as "being located on", "joined to", "connected to", "attached to", or "coupled to" another element or layer, it can be directly located on, joined, connected, attached, or coupled to another element or layer, or there may be intermediate elements or layers. In contrast, when an element is referred to as "directly on another element or layer", "directly joined to", "directly connected to", "directly attached to", or "directly coupled to" another element or layer, there may be no intermediate elements or layers. Other words used to describe the relationship between elements should be interpreted in a similar manner (for example, "between" versus "directly between", "adjacent" versus "directly adjacent", etc.). As used herein, the term "and / or" includes any and all combinations of one or more of the related listed items.

[0068] In this document, example embodiments of the present disclosure will be described in more detail with reference to the accompanying drawings. As used herein, expressions such as "at least one of..." modify the entire list of elements when following a list of elements, rather than modifying individual elements in the list. For example, the expression "at least one of a, b, and c" should be understood to include only a, only b, only c, both a and b, both a and c, both b and c, or all of a, b, and c.

[0069] The terms used herein are only for describing specific exemplary configurations and are not intended to be limiting. As used herein, the singular articles "a", "an", and "the" may also be intended to include the plural forms, unless it is clearly stated otherwise in the context. The terms "comprising", "including", and "having" are inclusive and thus specify the presence of the specified features, steps, operations, elements, and / or components, but do not preclude the presence or addition of one or more other features, steps, operations, elements, components, and / or their combinations. The method steps, processes, and operations described herein should not be construed as necessarily requiring them to be performed in the specific order discussed or illustrated, unless specifically identified as an order of performance. Additional or alternative steps may be employed.

[0070] As used herein, phrases such as "in one embodiment", "according to one embodiment", "in some embodiments", etc. generally refer to the fact that the specific feature, structure, or characteristic after such phrase may be included in at least one embodiment of the present disclosure. Thus, the specific feature, structure, or characteristic may be included in more than one embodiment of the present disclosure, such that these phrases do not necessarily refer to the same embodiment. As used herein, the terms "example", "exemplary", etc. are used "as an example, instance, or illustration. Any embodiment, aspect, or design described herein as "example" or "exemplary" is not necessarily to be construed as preferred or superior to other embodiments, aspects, or designs. Instead, the use of the terms "example", "exemplary", etc. is intended to present concepts in a specific manner.

[0071] The filtering components in the related art generally adopt High Efficiency Particulate Air Filters (HEPA). Some of the particle sizes in the removed HEPA filter elements are larger than 200 μm. According to the design concept, the particles with a particle size of 200 μm should be present in the dust collection bucket. It has been found through research that when the bottom cover is opened at one time, all the dust of all particle sizes is poured out together, resulting in dust flying. The large-particle-size particles in the dust collection bucket enter the filtering component from the dust outlet of the dust cup, thus causing the filtering component to be blocked and shortening the service life of the filtering component.

[0072] Based on the above research, embodiments of the present disclosure provide a multi-cone cyclone cup structure, a vacuum cleaner, and a method of using the same. By providing a two-stage opening method, when cleaning the dust in the dust collection bucket 100, the dust cup 210 is not opened, thereby preventing large particles from entering the filter assembly 250 and extending the service life of the filter assembly 250.

[0073] Regarding the defects existing in the above solutions, they are all the results obtained by the inventors through practice and careful research. Therefore, the process of discovering the above problems and the solutions proposed by the present disclosure in this article for the above problems should all be the contributions made by the inventors to the present disclosure during the process of the present disclosure.

[0074] It should be noted that similar reference numerals and letters represent similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0075] The following will describe in detail some embodiments of the present invention with reference to the drawings. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0076] Please refer to Figure 1 and Figure 2 At least one embodiment provides a multi-cone cyclone cup structure, including: a dust collection bucket 100, a side wall of which is provided with an air inlet 110; a multi-cone cyclone separator 200, which is arranged in the dust collection bucket 100; a bottom cover 300, which is rotatably connected to the bottom of the dust collection bucket and is hermetically connected to the dust collection bucket 100; wherein, a groove 310 is formed in the middle of the bottom cover 300; a rubber plug 320 is arranged in the groove 310; the rubber plug 320 is connected to the bottom of the groove 310 through a return spring 330, and the rubber plug 320 is inserted into the dust outlet 211 of the dust cup 210 of the multi-cone cyclone separator 200 and is hermetically connected to the dust cup 210.

[0077] The bottom cover 300 is provided with a two-stage opening method; when opening at the first stage, the bottom cover 300 opens the bottom of the dust collection bucket 100. At this time, the rubber plug 320 is inserted into the dust outlet 211 of the dust cup 210; when opening at the second stage, the bottom cover 300 opens the bottom of the dust collection bucket 100, and at the same time, the rubber plug 320 is pulled out of the dust outlet 211 of the dust cup 210 by an external force.

[0078] It should be noted that when opening at the first stage, the opening state of the bottom cover 300 is as shown by the arrow a in Figure 2 ; when opening at the second stage, the opening state of the bottom cover 300 is as shown by the arrow b in Figure 2 .

[0079] By setting a two - stage opening method, when opening the cover at the first stage, the internal dust cup 210 is blocked to complete the cleaning of the particles in the dust collection bucket 100. Then, when opening the cover at the second stage, the rubber plug 320 is pulled out from the dust cup 210 to complete the cleaning of the particles in the dust collection bucket 100. Thus, when opening the cover, the dust raising in the dust collection bucket 100 is prevented from entering the multi - cone cyclone cup separator 200 from the dust cup 210, and further, large - particle - size particles are prevented from entering the filter assembly 250, extending the service life of the filter assembly 250.

[0080] Among them, the opening direction of the bottom cover 300 is as Figure 2 shown by F in

[0081] It should be noted that since the accumulation speed of particles in the dust collection bucket 100 is much greater than that in the dust cup 210, by adopting the two - stage opening method, the particles in the dust collection bucket 100 can be cleaned specifically, and then the opening times of the dust cup 210 can be reduced. Thus, the risk of small - particle - size particles in the dust cup entering the filter assembly 250 is reduced, and the service life of the filter assembly 250 is extended.

[0082] Please continue to refer to Figure 2 , the multi - cone cyclone cup separator 200 further includes: an inner cylinder 220; a separation cavity 230, in which a plurality of conical cavities are provided; an outer - layer filter cylinder 240, which is arranged between the inner cylinder 220 and the dust cup 210; a filter assembly 250, which is arranged at the top of the separation cavity 230 and is communicated with an external air source 400; among them, the dust cup 210 is in a horn shape, and the rubber plug 320 is inserted into the dust outlet 211 at the bottom of the dust cup 210.

[0083] The dust cup 210 collects the particles separated by the separation cavity 230. At the same time, the rubber plug 320 blocks the dust outlet 211 of the dust cup 210, thus preventing the particles in the dust collection bucket 100 from being mixed with the particles in the dust cup 210, and further preventing large - particle - size particles from entering the filter assembly 250, extending the service life of the filter assembly 250.

[0084] Please refer to Figure 2 and Figure 3 , a connecting ring 260 is arranged between the dust cup 210 and the outer - layer filter cylinder 240; the connecting ring 260 is made of an elastic material; when opening the cover at the second stage, when the rubber plug 320 is pulled out from the dust outlet 211 of the dust cup 210 by an external force, the connecting ring 260 is pulled to deform. After the rubber plug 320 is pulled out, the connecting ring 260 rebounds, driving the dust cup 210 to vibrate.

[0085] By pulling out the rubber plug 320, the connecting ring 260 is deformed. After the rubber plug 320 is completely pulled out, the connecting ring 260 rebounds, driving the dust cup 210 to vibrate, thereby accelerating the discharge of particles in the dust cup 210.

[0086] Please continue to refer to Figure 2 and Figure 3 The multi-cone cyclone cup separator 200 further includes: a backflow prevention cover 270; the backflow prevention cover 270 is disposed below the outer filter cartridge 240; and the backflow prevention cover 270 is connected to the outer side wall of the connecting ring 260. When the connecting ring 260 rebounds, it drives the backflow prevention cover 270 to vibrate, shaking off the particles attached to the lower part of the backflow prevention cover 270.

[0087] It should be noted that the dust collection bucket 100 is used to collect particles with a particle size greater than 200 μm; the dust cup 210 is used to collect particles with a particle size between 50 μm and 200 μm; when opening the cover at the first level, the particles in the dust collection bucket 100 are cleaned; when opening the cover at the second level, the particles in the dust cup 210 are cleaned.

[0088] Please refer to Figure 2 and Figure 3 The side wall of the groove 310 extends upward to form a guide ring 311; the rubber plug 320 includes: a piston body 321 and a plug post 322; the plug post 322 is disposed at the bottom of the piston body 321; the diameter of the piston body 321 is adapted to the diameter of the dust outlet 211 of the dust cup 210; the plug post 322 is connected to the bottom of the groove 310 through a return spring 330, and when the bottom cover 300 is closed on the bottom of the dust collection bucket 100, the plug post 322 is inserted into the guide ring 311.

[0089] By providing the guide ring 311, it assists the rubber plug 320 to be inserted into the dust outlet 211 of the dust cup 210. At the same time, the guide ring 311 blocks the particles in the dust collection bucket 100 to prevent the particles in the dust collection bucket 100 from entering the dust cup 210.

[0090] Please refer to Figure 3 and Figure 4 The edge of the bottom cover 300 is axially provided with a circular ring groove 340; a sealing ring 350 is disposed in the circular ring groove 340; when the bottom cover 300 is closed on the bottom of the dust collection bucket 100, the bottom of the dust collection bucket 100 is inserted into the circular ring groove 340, and the gap between the bottom cover 300 and the dust collection bucket 100 is sealed by the sealing ring 350.

[0091] In a preferred embodiment, a plurality of air channels 360 are provided inside the bottom cover 300 to communicate the groove 310 with the annular groove 340; when opening the cover for the first stage, the rubber plug 320 remains inserted into the dust outlet 211 of the dust cup 210, and a negative pressure is formed when the guiding ring 311 separates from the plug post 322, so as to adsorb the sealing ring 350 in the annular groove 340 through the air channels 360.

[0092] Due to the negative pressure formed when the guiding ring 311 separates from the plug post 322, the gas flow direction is as shown by F in Figure 4 , and the adsorption direction of the sealing ring 350 is as shown by F1 in Figure 4 , thus preventing the sealing ring 350 from separating from the annular groove 340 when the bottom cover 300 is opened.

[0093] Please refer to Figure 5 , in a preferred embodiment, the number of the air channels 360 is multiple.

[0094] Please refer to Figure 6 , at least one embodiment further provides a vacuum cleaner, including: an air source 400 and the multi-cone cyclone cup structure as described above; the air source 400 is arranged on the top of the multi-cone cyclone cup structure.

[0095] During operation, the air source 400 generates a negative pressure to suck gas from the air inlet of the dust collection barrel 100, and separates the particles in the gas through the multi-cone cyclone cup structure.

[0096] Please refer to Figure 7 , at least one embodiment further provides a usage method applied to the vacuum cleaner as described above. When the vacuum cleaner needs to be cleaned, the usage method includes:

[0097] Step S110, opening the bottom cover 300 to the first-stage cover-opening state to clean the particles in the dust collection barrel 100;

[0098] Step S120, after the particles in the dust collection barrel 100 are cleaned, opening the bottom cover 300 to the second-stage cover-opening state to clean the particles in the dust cup 210.

[0099] Among them, the particle size of the particles in the dust collection barrel 100 is greater than 200 μm, and the particle size of the particles in the dust cup 210 is between 50 μm and 200 μm.

[0100] It should be noted that since the accumulation speed of the particles in the dust collection barrel 100 is much greater than that of the particles in the dust cup 210, adopting the two-stage cover-opening method can specifically clean the particles in the dust collection barrel 100, thereby reducing the opening times of the dust cup 210, further reducing the risk of large-particle-size particles entering the filter assembly 250, and prolonging the service life of the filter assembly 250.

[0101] In summary, the present invention provides a multi-cone cyclone cup structure, a vacuum cleaner and a method of using the same. The multi-cone cyclone cup structure includes: a dust collection bucket 100, with an air inlet 110 provided on its side wall; a multi-cone cyclone cup separator 200, which is arranged inside the dust collection bucket 100; a bottom cover 300, rotatably connected to the bottom of the dust collection bucket and hermetically connected to the dust collection bucket 100. Among them, a groove 310 is provided in the middle of the bottom cover 300; a rubber plug 320 is arranged in the groove 310; the rubber plug 320 is connected to the bottom of the groove 310 through a return spring 330, and the rubber plug 320 is inserted into the dust outlet 211 of the dust cup 210 of the multi-cone cyclone cup separator 200 and is hermetically connected to the dust cup 210; the bottom cover 300 is provided with a two-stage opening method. When opening the cover at the first stage, the bottom cover 300 opens the bottom of the dust collection bucket 100. At this time, the rubber plug 320 is inserted into the dust outlet 211 of the dust cup 210. When opening the cover at the second stage, the bottom cover 300 opens the bottom of the dust collection bucket 100, and at the same time, the rubber plug 320 is pulled out of the dust outlet 211 of the dust cup 210 by an external force. By setting the two-stage opening method, when opening the cover at the first stage, the internal dust cup 210 is blocked to complete the cleaning of the particles in the dust collection bucket 100, and then the cover is opened at the second stage to pull the rubber plug 320 out of the dust cup 210 to complete the cleaning of the particles in the dust collection bucket 100, thereby avoiding the dust in the dust collection bucket 100 from entering the multi-cone cyclone cup separator 200 from the dust cup 210 when opening the cover, and further avoiding large-particle-size particles from entering the filter assembly 250, and prolonging the service life of the filter assembly 250.
