[0042] In the description of the present invention, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0043] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0044] As Figures 1-3 shown, it is a preferred embodiment of the filter assembly of the present invention. This filter assembly is applicable to cleaning devices such as mite removers and vacuum cleaners. The filter net in the filter assembly can filter the air twice, so that the utilization rate of the filter net is relatively high, the dust filtration efficiency is higher, the dust removal rate is high, the filtering effect is better, and the user experience is improved.

[0045] The filtering component includes a bracket 1, a filtering element 2, and a filter net 3. The bracket 1 is the supporting component of the whole filtering component, providing structural strength for the filtering component. Both the filtering element 2 and the filter net 3 are used to filter dust in the air. The filtering element 2 is arranged inside the bracket 1, and the filter net 3 is sleeved outside the bracket 1. Moreover, the axial length of the filter net 3 is greater than that of the filtering element 2, and the filtering element 2 and the filter net 3 are partially overlapped. That is to say, the whole filtering component is an axisymmetric structure.

[0046] Furthermore, overall, the bracket 1 includes a first bracket part 101 and a second bracket part 102. The first bracket part 101 and the second bracket part 102 are arranged axially and communicate with each other. Air can enter the inside of the second bracket part 102 from the inside of the first bracket part 101. The filter net 3 is sleeved outside the first bracket part 101 and the second bracket part 102, and the filtering element 2 is arranged inside the second bracket part 102. That is to say, the filtering element 2 and the filter net 3 are overlapped at the second bracket part 102. There is a single-layer filtering structure of the filter net 3 at the first bracket part 101, while there is a two-layer filtering structure of the filter net 3 and the filtering element 2 at the second bracket part 102. The filter net 3 can filter the air twice, thus making full use of the filter net and improving the dust filtering efficiency.

[0047] Furthermore, the first bracket part 101 includes a first connecting plate 104, a second connecting plate 105, and a plurality of first support columns 103. The two ends of the first support column 103 are respectively connected to the first connecting plate 104 and the second connecting plate 105. The first support columns 103 are arranged at intervals in the circumferential direction, and the outer wall of the first support column 103 is in contact with the inner wall of the filter net 3. Specifically, both the first connecting plate 104 and the second connecting plate 105 are arranged in a direction perpendicular to the axis of the bracket 1, and the first support column 103 is arranged parallel to the axis of the bracket 1. Preferably, there are three first support columns 103, and the three first support columns 103 are evenly arranged at intervals in the circumferential direction, so as to ensure the structural strength of the filtering component, make the filter net 3 not easily deformed, and the connection mode of the two ends of the first support column 103 to the first connecting plate 104 and the second connecting plate 105 can be welding or the like.

[0048] Further, the second bracket portion 102 includes a third connecting plate 106 and a plurality of second support columns 107. The two ends of the second support columns 107 are respectively connected to the second connecting plate 105 and the third connecting plate 106. The second support columns 107 are arranged at intervals in the circumferential direction. The outer wall of the second support columns 107 is attached to the inner wall of the filter net 3, and the inner wall of the second support columns 107 is attached to the outer wall of the filter element 2. Specifically, the third connecting plate 106 is arranged in a direction perpendicular to the axial direction of the bracket 1, and the second support columns 107 are arranged parallel to the axial direction of the bracket 1. Preferably, the second support columns 107 are also arranged in three, and the three second support columns 107 are evenly arranged at intervals in the circumferential direction, so as to further ensure the structural strength of the filter assembly and make the filter net 3 not easily deformed. The connection modes of the two ends of the second support columns 107 with the second connecting plate 105 and the third connecting plate 106 can be welding or the like. In this embodiment, for the convenience of structural arrangement, the length directions of the first support columns 103 and the second support columns 107 coincide.

[0049] Further, in this embodiment, the whole filter assembly is in a frustum shape to adapt to the installation space.

[0050] Preferably, the filter element 2 is made of a Hepa net; the filter net 3 is made of a metal filter net. Among them, the metal filter net can filter large particles of dust in the air, and the Hepa net can filter dust with a smaller diameter, thereby enhancing the filtering effect of the filter assembly. In addition, the filter element 2 is also in a frustum shape.

[0051] Preferably, the filter element 2 can be snap-fitted into the second bracket portion 102, and the filter net 3 can tightly wrap the first bracket portion 101 and the second bracket portion 102, so that the filter assembly becomes an integral structure, which is convenient for installation and disassembly.

[0052] As Figures 4-8 shown, this embodiment also provides a dust cup assembly, including: a dust cup housing 4 and the filter assembly provided in this embodiment. A filter assembly installation cavity 401 and a dust collection cavity 402 that communicate with each other are formed in the dust cup housing 4. The dust collection cavity 402 is used to collect the dust separated from the air, and the filter assembly installation cavity 401 is used to install the filter assembly. Of course, a separation structure for separating the dust in the air is also provided in the filter assembly installation cavity 401. Since the present invention does not involve the specific separation structure, it will not be described in detail here.

[0053] The inner wall shape of the filter component installation cavity 401 matches the filter component. The filter component is installed in the filter component installation cavity 401. The dust cup housing 4 is provided with an air inlet channel and an air outlet channel. Part of the filter net 3 of the filter component is arranged in the air inlet channel, and the filter element 2 and the remaining part of the filter net 3 of the filter component are arranged in the air outlet channel. That is to say, during the air intake process, the filter net 3 filters the air once, and during the air outlet process, the filter net 3 also filters the air once, so as to realize the two - time filtration of the air by the filter net 3. During the air outlet process, the filter element 2 also filters the air once, so that the air entering the dust cup assembly can be filtered three times in total, and the filtering effect is good.

[0054] Specifically, the filter component installation cavity 401 and the dust collection cavity 402 are communicated through a notch 403. The notch 403 is arranged on the adjacent side walls of the filter component installation cavity 401 and the dust collection cavity 402. After the air is filtered and separated in the filter component installation cavity 401, the separated dust will enter the dust collection cavity 402 through the notch 403 for collection. After being filled with dust, it can be emptied manually.

[0055] Further, an air inlet 404 and an air outlet 405 are formed on the dust cup housing 4. The air inlet 404 is communicated with the air inlet channel, and the air outlet 405 is communicated with the air outlet channel. In this embodiment, the air inlet 404 and the air outlet 405 are arranged on the same side of the dust cup housing 4, and the air inlet 404 and the air outlet 405 are arranged in parallel to facilitate the structural layout.

[0056] Further, in the filter component installation cavity 401, the air inlet 404 and the air outlet 405 are separated by a partition plate 5. The inner side of the partition plate 5 has a through - hole suitable for installing the filter component. Preferably, the partition plate 5 is a spiral partition plate. After the air entering from the air inlet 404 is guided by the partition plate 5 and generates a fixed rotation direction, dust and other impurities in the air will be thrown into the dust collection cavity 402 through the notch 403 for collection.

[0057] In addition, the dust cup assembly of this embodiment further includes a cover body 6 for sealing the dust cup assembly. In this embodiment, there are two cover bodies 6, which are respectively covered at both ends of the dust cup housing 4.

[0058] The following describes the process of installing the filter component of this embodiment into the dust cup housing 4:

[0059] Insert the end with a smaller diameter of the filter component into the filter component installation cavity 401, and the installation direction is as shown by the arrow in Figure 6 When the filter component is completely inserted into the filter component installation cavity 401, cover the cover body 6 on the dust cup housing 4 to seal the dust cup assembly, and the cover body 6 can also be locked by structures such as a buckle to prevent it from falling off.

[0060] This embodiment also provides a cleaning device, including a main body and the dust cup assembly provided in this embodiment. The dust cup assembly is detachably mounted on the main body. The connection manner between the dust cup assembly and the main body can be snap connection or the like. Specifically, the cleaning device in this embodiment is a mite remover. Of course, the mite remover in this embodiment also includes other structures and components that existing mite removers all have. Since these structures and components are not involved in the present invention, they will not be described in detail here.

[0061] As Figure 9 shown, in order to further understand the working process of the filter assembly in this embodiment, the following describes the air filtration process of the filter assembly in this embodiment with reference to the accompanying drawings ( Figure 9 the arrow direction in is the air flow direction):

[0062] First, the outside air enters the intake passage from the air inlet 404. Since a part of the filter net 3 is arranged in the first support part 101, the filter net 3 will perform the first filtration on the entering air. Then the air enters the second support part 102. In the second support part 102, the air will flow in a rotating direction under the action of the spiral partition. And during this process, the air will be filtered again by the filter element 2 and the filter net 3 and discharged from the air outlet 405. The dust and other sundries filtered out will be thrown into the dust collection cavity 402 through the notch 403 for collection.

[0063] In the above process, the filter net 3 will filter the air twice, and the filter element 2 will filter the air once. That is to say, the air entering the dust cup assembly needs to be filtered three times in total. The utilization rate of the filter net is high, making the dust filtration effect better.

[0064] In other embodiments, the cleaning device can also be a vacuum cleaner.

[0065] Obviously, the above embodiments are only examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
