Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cleaning appliances, in particular to a dust cup and a dust collector. BACKGROUND

[0002] The basic working principle of a dust collector is that dust is sucked in through a suction port and filtered through a filter to trap the dust, and the filtered gas is discharged. One type of filter includes a filter screen, so the mesh holes on the filter screen are prone to some degree of blockage, thereby affecting the performance of the dust collector. Therefore, the industry has researched how to clean the filter screen. The structure for cleaning the filter screen can be referred to as a dust scraping structure or a wiping structure. The current cleaning structure for cleaning the filter screen can be roughly divided into the following types:

[0003] 1. The cleaning structure designed for the filter screen of a cyclone separation filter. Since the structure of cyclone separation is considered, the current structure design mainly adopts the form of axial movement of the dust scraping member relative to the filter screen for dust scraping and cleaning. The differences between various parties mainly lie in the specific design of the dust scraping member, the design of the dust scraping operation structure, or further improvements and research made to adapt to the design of a handheld type. For example, the cleaning tool for sliding the filter to clean the filter (CN1313046C), the dirt separator (CN109984671A), the wiping assembly and dust cup (CN207666537U), the cleaning device for a dust collector and the dust collector having the same (CN211862694U), and the wiping assembly and dust cup (CN207666537U).

[0004] 2、Difference 1, although also cyclone separation, but set is the rotating cleaning structure, due to the involvement of cyclone separation and other factors, so increase the difficulty of setting rotating cleaning structure, so this kind of structure research is less, although there is a certain research, but the current scheme proposed, there are mainly two problems, one is the structure is very complex, the whole separator volume is larger, suitable for horizontal dust collector, when the filter screen is rotated, the transmission is realized through the through piece set in the inner circumferential filter screen, the transmission is complex, in addition, the transmission assembly occupies the space in the filter screen, if the cyclone separation outside the filter screen is used as the first separation, then there is not enough space in the filter screen to add the related components of the second separation, such as the dust collecting device and the electric dust collector with the dust collecting device disclosed in CN110236448A, the second is not the filter screen, but the grid for filtering, the grid has a relatively thick volume in the radial direction, the wiping element is located outside the grid, in the working state, the wiping element is stationary, the grid rotates continuously, the wiping element continuously rubs the grid, so an additional power mechanism is needed to make the grid rotate continuously, in addition, the wiping element is generally set to one, otherwise the number is too large, which is not conducive to continuous rotation, in addition, the wiping element is relatively thick due to the suspension of the lower end and the need to overcome the force of the grid, so it has an adverse effect on the cyclone of the cyclone separation chamber, such as the cyclone dust collecting device for vacuum cleaner disclosed in CN1462604A.

[0005] 3、Difference 1, 2, the third is mainly straight through the filter type, which separates dust by directly filtering through the filter, rather than using cyclone separation, the space on the inlet side of the filter is mainly used as a dust bin, not a cyclone chamber, the third is mainly used for simple dust collectors, small dust collectors, vehicle-mounted dust collectors, etc., such as the dust and gas separation device and the dust collector disclosed in CN110840331A, and the dust collector with convenient cleaning disclosed in CN212788395U.

[0060] The present application is further described in detail below:

[0061] It is particularly noted herein that "dust" is a common or general term for separated or filtered substances in the dust cup industry, not only referring to dust.

[0062] A dust cup includes a cup body 1, a cup cover 2, and a separation unit,

[0063] The cup body 1 is used to form a dust bin and can accommodate the separation unit, which includes both partial accommodation and full accommodation;

[0064] ​The cup cover 2 is openably connected to one end of the cup body 1, and is used for closing one end of the cup body 1 when being closed, and is used for opening one end of the cup body 1 for dust pouring operation when being opened.

[0065] The separating unit comprises a filter screen 3 for filtering.

[0066] The wiping member 8 is used for cleaning the filter screen 3.

[0067] The connecting part 4 is further included, the cup cover 2 comprises a rotating member 5, the rotating member 5 is rotatably connected with the cup cover 2, after the cup cover 2 is closed, the rotating member 5 is in transmission connection with the connecting part 4, the rotating member 5 drives the wiping member 8 to move in the circumferential direction of the filter screen 3 through the connecting part 4 by rotating, or the rotating member 5 drives the filter screen 3 to rotate by itself through the connecting part 4, and the wiping member 8 is located in the circumferential direction of the filter screen 3, or the rotating member 5 drives the filter screen 3 to rotate by itself through the connecting part 4, and drives the wiping member 8 to move in the circumferential direction of the filter screen 3 at the same time, the filter screen 3 and the wiping member 8 have the same rotating direction but have a speed difference, or the filter screen 3 and the wiping member 8 have opposite rotating directions.

[0068] The separating unit comprises a supporting part for supporting the filter screen 3, one end of the connecting part 4 is connected with the wiping member 8 or the supporting part, and the other end of the connecting part 4 is detachably connected with the cup cover 2. Thus, the structure is relatively simple.

[0069] The supporting part is connected with the end part of the filter screen 3, the supporting part can be connected with one end part of the filter screen 3, or can be connected with two end parts of the filter screen 3, or the supporting part is sleeved with the filter screen 3, the supporting part is inside, or the supporting part is sleeved with the filter screen 3, and the supporting part is connected with the end part of the filter screen 3, or the supporting part is integrated with the filter screen 3, or the connecting part 4, the supporting part and the filter screen 3 are integrated. Thus, the ventilation holes of the filter screen 3 are less shielded. The filter screen 3 mainly has two forms, one is a separate filter screen 3, and the other is an integrated filter screen 3. The separate filter screen 3 mainly refers to a metal filter screen 3, and the integrated filter screen 3 is formed by a plastic forming technology, for example, a first axial component or a second axial component provided with ventilation holes is integrally formed, and the filter screen 3 is also integrally formed at the same time. In this example, the separate filter screen 3 is described.

[0070] In the first embodiment, the rotating member 5 drives the filter screen 3 to rotate by itself through the connecting part 4, and the wiping member 8 is located in the circumferential direction of the filter screen 3, and the inner ring 6 is used as the supporting part.

[0071] For example, Figure 1As shown, a dust cup is disclosed, the dust cup comprises a front end and a rear end, the rear end is connected with a hepa filter 22, the dust cup is configured to suck dirty air into through an inlet 26, the dirty air is separated by a separation unit and then flows downstream to the hepa filter 22, and then is sucked into by a fan assembly 23 and finally discharged into the environment. The front end of the dust cup is provided with a cup cover 2 of the dust cup which can be opened, the cup cover 2 is rotatably connected with a cup body 1 of the dust cup at a lower end, and is provided with a torsion spring 28, so that once the front side of the cup cover 2 is released, the cup cover 2 can be automatically flipped open forward.

[0072] The separation unit comprises an inner ring 6 and an outer ring 7 which are relatively rotatable, the inner ring 6 is located inside the filter screen 3, and the outer ring 7 is located outside the filter screen 3, the outer ring 7 comprises connecting spokes which serve as wiping members 8, the filter screen 3 is connected with the inner ring 6, the rotating member 5 drives the inner ring 6 to rotate relative to the outer ring 7 through the connecting part 4, at the same time, the inner ring 6 drives the filter screen 3 to rotate together, the wiping members 8 are stationary, that is, the connecting spokes of the outer ring 7 are stationary, and the relative rotation between the aforementioned inner ring 6 and the outer ring 7 enables the connecting spokes of the outer ring 7 to clean the outer side surface of the filter screen 3.

[0073] The connecting spokes can be one or multiple, in this example, the connecting spokes are multiple and are uniformly arranged along the circumferential part of the outer ring 7, and the connecting spokes are arranged along the axial direction of the filter screen 3. The outer ring 7 is jointly constituted by the connecting spokes and the circumferential part.

[0074] The inner ring 6 and the outer ring 7 can adopt different shapes, and the circumferential part can be one or multiple, in this example, the inner ring 6 and the outer ring 7 are each provided with one circumferential part at both ends of the connecting spokes, that is, the inner ring 6 is provided with two circumferential parts, and the outer ring 7 is also provided with two circumferential parts.

[0075] In this example, the filter screen 3 is connected with the inner ring 6, the connecting part 4 is connected with the inner ring 6 to form a first axial assembly, and the first axial assembly carries the filter screen 3 to be axially connected with or separated from the outer ring 7 through a detachable axial sleeve, as Figure 8 shown, the filter screen 3 has also been removed, and only the connecting part 4 and the inner ring 6 are left. In this way, the filter screen 3 is conveniently detached, on the one hand, the filter screen 3 can be removed together with the first axial assembly by disassembling, and on the other hand, the space inside the filter screen 3 is exposed, which is convenient for cleaning the inside, especially when the space inside the filter screen 3 is provided with a separation structure, the aforementioned structure is particularly convenient for cleaning the separation structure. In summary, the axial separable design of the separation unit is realized, which is an additional feature of the present application and has the above additional technical effects.

[0076] As shown in Figure 3 , 5 , the connecting part 4 is provided as a connecting column 9 or a connecting pipe which is arranged separately from the inner space of the cup body 1 outside the filter screen 3. In this way, it is beneficial for hygiene, and the dust in the inner space of the cup body 1 outside the filter screen 3 cannot enter the connecting column 9 or the connecting pipe.

[0077] As shown in Figure 3 , 5 , the connecting part 4 is located between the cup cover 2 and the filter screen 3, and the connecting part 4 and the cup body 1 form an annular cavity 12, which is used to constitute a dust bin. In this way, on the one hand, the transmission distance is short, and on the other hand, the connecting part 4 is used as a part of the dust bin, which is conducive to simplifying the structure.

[0078] As shown in Figure 3 , 5 , it also includes a circumferential extension 13 as a dust blocking eave, which is located at the lower end or the lower side of the filter screen 3, and the circumferential extension 13 is provided with a gap 14 between the inner circumferential wall of the cup body 1 and the circumferential extension 13, and the circumferential extension 13 and the annular cavity 12 constitute a dust bin. In this way, the circumferential extension 13 and the connecting part 4 can form a dust bin structure with better performance. On the one hand, the performance is good, that is, it is not easy for the separated dust to rise again to the position of the filter screen 3, and on the other hand, because the rotating dust scraping structure is added, the foregoing design is conducive to simplifying the structure, and the connecting part 4 is used as a dust bin at the same time.

[0079] The outer circumferential surface of the connecting part 4 is arc-shaped. In this way, the dust is not easy to hang and is easy to pour out of the dust bin.

[0080] As shown in Figure 3 , one end of the connecting pipe is provided with an opening, and the one end of the connecting pipe is detachably and sealingly connected with the cup cover 2, and the sealing connection is realized through a sealing gasket 15, and the other end of the connecting pipe is in communication with the internal space of the filter screen 3. After the cup cover 2 is closed, the connecting pipe is used to store the dust in the filter screen 3, and when the cup cover 2 is opened, the one end of the connecting pipe is opened for dust pouring operation. In this way, the dust in the internal space of the filter screen 3 can be conveniently cleaned. In addition, by using the foregoing design, other separation structures can be further arranged in the filter screen 3 or in communication with the filter screen 3, so as to obtain better separation effect.

[0081] In this example, the cup body 1 is provided with a cyclone guiding structure, which forms a cyclone separation in the cup body 1. The air separated by the cyclone separation enters the internal space surrounded by the filter screen 3, and the separation structure formed in the cup body 1 is referred to as a first separation structure. The cyclone guiding structure realizes cyclone through the tangential inlet part 27 arranged in the cup body 1.

[0082] The second separation structure is arranged in communication with the filter screen 3, and the air entering the filter screen 3 is separated by the second separation structure, and the separated dust is collected by the connecting pipe. In this way, on the one hand, the separation is further carried out, and on the other hand, the foregoing design is conducive to simplifying the structure, and the connecting part 4 is used as a dust discharge pipe at the same time.

[0083] The second separation structure comprises one or more multi-cone separation structures, in this case two, a lower multi-cone separation structure 16 and an upper multi-cone separation structure 17, which are axially fitted together. As shown in Figure 9 , 10 The lower multi-cone separation structure 16 is connected to the upper end circumferential part of the outer ring 7 by a plurality of circumferentially arranged connecting ribs 30, thereby providing support for the lower multi-cone separation structure 16, and annular spaces are formed between the connecting ribs 30 and the connecting spokes of the outer ring 7, in which the inner ring 6 carrying the filter screen 3 is axially fitted, which can be understood with reference to Figure 4 , 6 , 9, 10.

[0084] The connecting pipe is provided with a receiving section for receiving the separation cones of the multi-cone separation structure. In this way, on the one hand, the axial length of the separation unit is reduced, and on the other hand, the structure is simplified, and the connecting part 4 is used as a separation cone receiving space of the multi-cone separation structure. In this case, the receiving section is used to receive the main part of the separation cone of the lower multi-cone separation structure 16, as shown in Figure 3 .

[0085] When there are multiple layers of multi-cone separation structures, the air inlet 21 of the separation cone of the lowermost multi-cone separation structure 16 is provided with a wind baffle 18, and the separation cones of the multi-cone separation structures of the adjacent upper layers of the lowermost layer are distributed on the front and back sides of the wind baffle 18, i.e. a front separation cone 19 and a rear separation cone 20 are arranged on the front and back sides of the wind baffle 18, as shown in Figure 12 , so that the wind baffle 18 only leaves an upper opening, which is higher than the lower end of the filter screen 3, and air enters the air inlet 21 through the upper opening. In this way, on the one hand, the air flow entering the filter screen 3 is better distributed, and on the other hand, the structure is simplified and compact.

[0086] The cup cover 2 limits the position of the axially fitted inner ring 6 and outer ring 7, or the cup cover 2 limits the position of the axially fitted inner ring 6 and outer ring 7 after being closed, and the inner ring 6 and the outer ring 7 are further connected by a detachable connection structure after being axially fitted, in this case, both the cup cover 2 and the detachable connection structure are provided. In this way, in the daily long-term use, on the one hand, the axial connection stability of the inner ring 6 and the outer ring 7 is good, and on the other hand, the rotating dust scraping structure can be better realized, and the rotation is not loose.

[0087] In this case, the detachable connecting structure includes a connecting column 9 extending axially to one side of the cup cover 2, the connecting column 9 is sleeved inside and outside the connecting part 4, one end of the connecting column 9 located on one side of the cup cover 2 is provided with a reverse buckle 10, the reverse buckle 10 can be folded transversely through the middle slot, so as to facilitate the separation operation of the detachable axial sleeve of the inner ring and the outer ring, the other end of the connecting column 9 is fixed, in this case, the other end of the connecting column 9 is connected and fixed with the outer ring 7, and the connecting part 4 is connected with the inner ring 6, the connecting part 4 is provided with a connecting hole 11 which can be detachably connected with the reverse buckle 10, and the connection between the reverse buckle 10 and the connecting hole 11 constitutes a limit for the position of the axial sleeve of the inner ring 6 and the outer ring 7. In this way, the structure is relatively simple, the first axial assembly carries the filter screen 3 together with the outer ring 7 to be axially sleeved and separated through the detachable axial sleeve, which is convenient. In addition, the connecting column 9 is sleeved inside and outside the connecting part 4, so that the connecting column 9 is hidden in the connecting part 4, the structure is compact, and there is no influence on the outer peripheral surface of the connecting part 4, which is beneficial to dust separation work.

[0088] In this case, an adaptive structure for adaptive plug-in connection is arranged between the rotating part 5 and the connecting part 4.
